Abstract
A system for manufacturing an antenna includes a first stamping station, a pressure sensitive adhesive (PSA) alignment station, a bonding station, a second stamping station, and a ferrite shield station. The first stamping station receives a sheet of metallic material and stamps the sheet to form an antenna including traces, contacts, a carrier connected to the traces, and a tie-bar connected between the traces. The PSA alignment station receives the stamped antenna and aligns a PSA area of a pad with the traces, the PSA area being substantially the same shape as the traces. The bonding station bonds the PSA area to the traces after it has been aligned with the traces. The second stamping station performs a second stamping of the antenna and the PSA area to remove the carrier and the tie-bar. The ferrite shield station bonds a ferrite shield to the antenna stamped for a second time.

DETAILED DESCRIPTION
(32) The present invention relates to a method of manufacturing a stamped antenna.
(33)
(34)
(35) At a third station 29, a pressure sensitive adhesive (PSA) pad 30 is placed onto a fixture 32 or jig.
(36)
(37)
(38) The antenna biscuit 16 is then transferred to the third station 29 to be aligned with the PSA pad 30 and the fixture 32.
(39) The fixture 32, PSA pad 30 and antenna biscuit 16 are transferred to a fourth station 44 for bonding the antenna biscuit 16 with the PSA pad 30. The fourth station 44 includes rollers that provide pressure for activating the PSA 30 and bonding the antenna biscuit 16 with the PSA pad 30. Once bonded, the antenna biscuit 16, now with a PSA layer 30, is advanced to a fifth station 46 that includes a second precision high-speed stamping press for performing a second antenna stamping. The second stamping press performs a second stamping operation on the antenna biscuit 16 wherein the tie bars 20 are stamped and removed from each antenna 18a-e. The second stamping press stamps through the foil that makes up the tie bars 20, the PSA bonded to the tie bars 20, and the release liner 34. The carriers 22 will fall away upon stamping of the tie bars 20 because the carriers 22 are generally outside the adhesive area 36 of the PSA pads 30. As such, the second stamping operation effectively removes each individual antenna 18a-e from the antenna biscuit 16 so that each antenna 18a-e is by itself, but supported by the PSA pad 30.
(40) Once the second stamping is complete the release liner 34 can be peeled away, as shown in
(41) In an alternative embodiment, the antenna biscuit 16 and PSA pad 30 of

(48) The assembly station 110 could include a robotic device 112, which could have 3-axis movement, an adhesive applicator 114, and a robotic cylinder 116. The assembly station 110 receives the antennas and attaches the ferrite shields 88. In preparation for applying the ferrite shields 88 to the antennas, the adhesive applicator 114 removes the bottom liner of the adhesive cards 92, rolls the removed bottom liner onto a scrap roller, and places each adhesive card 92 into a tray of the robotic cylinder 116. The robotic cylinder 116 transfers the adhesive cards 92 to the robotic device 112. The robot device 112 could be a robotic pick-up pad that could be a vacuum pad attached to the end of an arm of the robotic device 112 to pick up the adhesive cards 92. The robotic device 112 includes pilot pins that engage the alignment holes 98 of the adhesive cards 92 and locate/align the adhesive cards 92. Once the adhesive cards 92 are ready for transferring, the robotic device 112 moves the adhesive cards 92 into alignment over the antennas, which are transferred by the pallet 70. The robot 112 then stamps the adhesive cards 92 onto the antennas, such that the adhesive areas 96 engage the antennas, and picks the antennas up. Next, the robotic device 112 moves the adhesive card 92 and antenna sub-assembly over the first fixture 84 containing the ferrite shields 88, and stamps down on the ferrite shields 88 to bond the ferrite shields 88 to the antennas and the adhesive cards 92. The antennas, including adhesive cards 92 and ferrite shields 88, are then transferred along the conveyor belt to a pick-and-pack station 118 where the antennas are removed from the conveyor 104, scrap is removed, and the antennas are packaged.
(49) Having thus described the invention in detail, it is to be understood that the foregoing description is not intended to limit the spirit or scope thereof. What is desired to be protected is set forth in the following claims.
