Abstract
Description
- This application claims the benefit of U.S. Provisional Application No. 60/335,560, filed Oct. 31, 2001.
- The invention relates to taper machines in which electronic parts are positioned within the compartments of a carrier tape, and in which a cover tape is laid over the carrier tape and sealed thereto to trap the parts within the compartments. More specifically, the invention relates to a method and apparatus for flattening the cover tape prior to the cover tape being sealed to the carrier tape.
- The present invention provides a flattening mechanism for flattening wrinkles out of cover tape prior to the cover tape being bonded to carrier tape. The flattening mechanism is biased against the cover tape and includes a leading edge that is angled with respect to the direction of travel of the cover tape. The leading edge may be defined by rollers or a plate. As the cover tape moves under the flattening mechanism, the wrinkles are flattened out to edge of the carrier tape sides. The cover tape is therefore substantially flat or planar as it is bonded to the carrier tape.
- Other features and advantages of the invention will become apparent to those skilled in the art upon review of the following detailed description, claims, and drawings.
- FIG. 1 is a side elevation view of a taper machine embodying the invention.
- FIG. 2 is a top plan view of the taper machine.
- FIG. 3 is a perspective view of a portion of carrier tape.
- FIG. 4 is a perspective view of the cover tape flattening assembly.
- FIG. 5 is a cross-section view taken along line5-5 in FIG. 2.
- FIG. 6 is a top view of the flattening mechanism in operation.
- FIG. 7 is a cross-section view taken along line7-7 in FIG. 2.
- FIG. 8 is a top plan view of an alternative flattening mechanism in operation.
- FIG. 9 is a bottom perspective view of the alternative flattening mechanism.
- Before one embodiment of the invention is explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and the arrangements of the components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being practiced or being carried out in various ways.

The use of “consisting of” and variations thereof herein is meant to encompass only the items listed thereafter. The use of letters to identify elements of a method or process is simply for identification and is not meant to indicate that the elements should be performed in a particular order.
- FIGS. 1 and 2 illustrate an inspection, handling, and
packaging apparatus 20 that includes asupport stand 24, an infeed carriertape drive wheel 26, a pick-and-place head ortransport 28, a carrier tape infeedreel 32 dispensingcarrier tape 34, a camera-over-tape or “COT”inspection module 36, acover tape reel 40 dispensingcover tape 41, a cover tape flattening, smoothing, orcombing mechanism 42, a sealingshoe 44, aresilient drive roller 48, abackup wheel 50, a camera-after-sealing inspection module or “CASI”module 52, and an outputreel packaging module 56. The support stand 24 supports a plurality of part input trays 60 that containparts 64 to be inspected and packaged. Thetransport 28 picks theparts 64 off the input trays 60, and transfers theparts 64 to thecarrier tape 34. Thetransport 28 is preferably a pick-and-place type transport utilizing a vacuum head. - The
carrier tape 34 is best illustrated in FIG. 3, and includes a pair offlanges 72 running along its length, andcompartments 76 formed between theflanges 72. One or both of theflanges 72 may includesprocket holes 80 to facilitate advancing thecarrier tape 34 through theapparatus 20 and/or other machinery. For example, the infeed carriertape drive wheel 26 may be a pinwheel having sprocket pins that engage thesprocket holes 80 of thecarrier tape 34. Thedrive wheel 26 may be driven under power by a motor (not illustrated) to pull thecarrier tape 34 off the infeedreel 32. Alternatively, thedrive wheel 26 may have a smooth or flat surface and/or be passive or not driven by a motor. - The
resilient drive roller 48 rotates under the power of a motor (not illustrated) to pull thecarrier tape 34 through theapparatus 20 in a downstream direction 82 (an upstream direction being opposite the downstream direction 82). Theflanges 72 of thecarrier tape 34 are pinched between thedrive roller 48 and thebackup wheel 50 to facilitate the advancement of thecarrier tape 34 under the influence of the rotatingdrive roller 48. Alternatively, thedrive roller 48 may include pins that engage thesprocket holes 80 in thetape flanges 72 to facilitate advancing thecarrier tape 34 through theapparatus 20. Thecarrier tape 34 is supported at itsflanges 72 by guide rails 84 (FIGS. 1, 5, and 7) that extend substantially the entire length of theapparatus 20. - Referring again to FIGS. 1 and 2, the
transport 28 places asingle part 64 into eachcompartment 76 of thecarrier tape 34. TheCOT inspection module 36 is downstream of thetransport 28, and includes a camera, which inspects theparts 64 in thecarrier tape compartments 76 as thecarrier tape 34 is advanced through theapparatus 20. - The
cover tape 41 is laid on top of thecarrier tape 34 downstream of theCOT inspection module 36, and is pulled through theapparatus 20 along with thecarrier tape 34. Thecover tape 41 is guided from thecover tape reel 40 to thecarrier tape 34 by a plurality oftensioning rollers 92. Thecover tape 41 extends between theflanges 72 and completely covers thecompartments 76. The adhesive, which is on thecover tape 41 surface, faces thecarrier tape 34. Heat activated cover tape has adhesive across the complete cover tape surface. Pressure sensitive activated cover tape has only twostrips 94 of adhesive (FIG. 4) that are located over theflanges 72 of thecarrier tape 34. The adhesive is used to seal thecover tape 41 to theflanges 72 of thecarrier tape 34. - Referring to FIGS. 1, 2, and4-6, the
flattening mechanism 42 is downstream 82 of thelast tension roller 92 such that both thecover tape 41 andcarrier tape 34 pass under theflattening mechanism 42. Theflattening mechanism 42 includes a length ofspring wire 96, a pair ofroller tubes 100, and a pair ofmounting clamps 104. To assemble theflattening mechanism 42, thespring wire 96 is extended longitudinally through theroller tubes 100, and thespring wire 96 is then bent into the shape illustrated. Themounting clamps 104 secure the ends of thespring wire 96 to asupport structure 106 alongside theguide rails 84. The resiliency of thespring wire 96 biases theroller tubes 100 downwardly against thecover tape 41. - The
spring wire 96 is bent at its center to define a peak that points in the upstream direction. Theroller tubes 100 are therefore angled or swept back from the center of thecover tape 41 in thedownstream direction 82 to the outer edges of thecarrier tape 34. Theroller tubes 100, which are preferably made of brass or any other suitable material, freely rotate about thespring wire 96 as thecarrier tape 34 andcover tape 41 pass under theflattening mechanism 42. The bottoms of theroller tubes 100 contact thecover tape 41 and define the leading edge of theflattening assembly 42. - Referring to FIG. 6, because the
roller tubes 100 are angled with respect to the longitudinal extent of thecover tape 41 andcarrier tape 34 and with respect to thedownstream direction 82, wrinkles in thecover tape 41 are flattened, smoothed, or combed to the edges of the carrier tape prior to thecover tape 41 andcarrier tape 34 moving under the sealing shoe 44 (i.e., thecover tape 41 is substantially free from wrinkles downstream 82 of the rollers 100). Theflattening mechanism 42 therefore helps to maintain thecover tape 41 in a substantially planar condition immediately prior to thecover tape 41 being bonded to thecarrier tape 34 by the sealingshoe 44. - Referring now to FIGS. 1 and 7, the
sealing shoe 44 is immediately downstream of, and should be as close as possible to, theflattening mechanism 42. The sealingshoe 44 includes asealing mechanism 108 that is either a spool-shaped wheel or longitudinal flat shoe. Thesealing mechanism 108 has flanges oredges 109 aligned over theflanges 72 of thecarrier tape 34, and in alignment with the lines ofadhesive 94 on thecover tape 41 if pressure sensitive adhesive is used. A downward force is applied to thesealing mechanism 108 to pinch thecover tape 41 andcarrier tape 34 together between the sealingflanges 109 and the guide rails 84. - If heat is required to activate the adhesive, heating elements110 (FIG. 7) may be inserted into the guide rails 84 under the sealing
shoe 44 for that purpose. Thus, as thecarrier tape 34 andcover tape 41 pass under the sealingshoe 44, the adhesive forms a bond (as at 112 in FIG. 6) between thecover tape 41 and thecarrier tape 34 to secure thecover tape 41 over thecompartments 76 of thecarrier tape 34 and thereby trap theparts 64 within thecompartments 76. - Referring back to FIGS. 1 and 2, the
CASI module 52 is downstream 82 of the sealingshoe 44 and includes a camera that looks down at thetape 34, 41 (substantially as seen in FIG. 6 downstream 82 of the rollers 100) and inspects the sealing bonding process for possible sealing shoe position errors or inconsistent sealing perimeters. By flattening thecover tape 41 prior to sealing it to thecarrier tape 34, theflattening mechanism 42 helps to reduce false rejections by theCASI module 52. Such false rejections may be caused by the camera of theCASI module 52 mistaking wrinkles in thecover tape 41 as flaws. - The loaded
carrier tape 34 is then wound onto the output reel-packagingmodule 56. Theapparatus 20 also includes a processor (not illustrated) that receives information from the COT andCASI modules parts 64 have been indicated by theinspection modules good parts 64 are taken from thecarrier tape 34 for their end use. - FIGS. 8 and 9 illustrate an alternative construction of the
flattening mechanism 42. Similar elements in these drawings are given the same reference numerals introduced above. In this construction, thespring wire 96 extends across thecover tape 41 andcarrier tape 34 substantially perpendicular to thedownstream direction 82 and to the longitudinal extent of thetapes rollers 100 are replaced with a flatteningplate 114 having angled edges. Thewire 96 extends through the flatteningplate 114, and the flatteningplate 114 is pivotal about thewire 96. A pair ofset collars 118 are mounted to thewire 96 on either side of the flatteningplate 114 to prevent theflattening plate 114 from sliding along thewire 96, and to maintain the flatteningplate 114 over thecover tape 41. - The
flattening plate 114 is angled or swept back from the center of thecover tape 41 in thedownstream direction 82 to the outer edges of thecarrier tape 34, substantially as therollers 100 in the above-described first construction are. Acavity 122 is provided in the bottom of the flatteningplate 114 to reduce the surface area of the flatteningplate 114 that is in contact with thecover tape 41. This in turn reduces the frictional forces applied to thecover tape 41 by the flatteningplate 114 and therefore reduces the pulling force required to move the cover andcarrier tapes apparatus 20. The flatteningplate 114 operates substantially as described above with respect to the first construction, except that the leading edge of the flatteningplate 114 slides (as opposed to rolling) over thecover tape 41 to flatten out wrinkles in the surface of thecover tape 41.
