Embodiment 1

[0024] A punching device for smart card module manufacturing according to the present invention includes a base 2 for placing a smart card module 1 and a laser emitting device 3 above the base 2 .

[0025] The laser emitting device 3 is provided with a laser light source 31, the laser light source 31 is connected to a laser positioning adjustment device 32, and the laser positioning adjustment device 32 carries out continuous positioning adjustment to the focal point of the laser beam emitted by the laser light source 31, so that the laser light source 31 emits The focus point of the laser beam travels according to the specified path, completes the operation of punching all the short-circuit holes 15 on the smart card module 1 without interruption, and removes all the flashes within the range of the short-circuit holes 15, and all the flashes outside the range of the short-circuit holes 15. Overflow or partial overflow.

Embodiment 2

[0037] In order to further reduce the cost and improve the utilization rate, at least three smart card modules 1 can be placed side by side in the base 2. The width of the strip 11 of the original smart card module 1 is generally 35mm, so now the width of the strip 11 in the smart card module 1 is 10mm. The design is narrower. Simultaneously, at least one laser light source 31 is equipped in the laser emitting device 3 above the base 2, and there can be only one laser light source 31, and the short circuit hole 15 is punched for all smart card modules 1 by the laser light source 31, and the flashing material 14 is removed, and the molding is removed. The flange 131 on the edge of 13 and the engraved traceability and anti-counterfeiting information 17; each smart card module 1 can also be equipped with a laser light source 31 separately to punch the short circuit hole 15, remove the flash 14, and remove the flange 131 on the edge of the molding 13 And the operation of engraving...

Abstract

The invention discloses a punching device for manufacturing a smart card module in the field of smart card manufacturing. The punching device comprises a base for placing the smart card module and a laser emitting device above the base. The laser emitting device is provided with at least one laser light source, all the laser light sources are connected with a laser positioning and aligning device for positioning and aligning a focus point of laser beams emitted from the laser light sources, and the laser beams emitted from the laser light sources are controlled by the laser positioning and aligning device so as to punch short circuit holes in the smart card module. The punching device achieves the technical effects that the smart card module with the short circuit holes punched has few burrs and no noise and dust are generated in the process of punching the short circuit holes; in the process of punching the short circuit holes in the smart card, no stress is applied on the smart card module so that failure or deformation of the smart card module can be avoided.

Description

technical field [0001] The invention relates to a punching device for smart card module manufacturing in the field of smart card module manufacturing. Background technique [0002] Smart card modules, especially contactless smart card modules, are widely used in important fields such as traffic cards, access control cards, ID cards, electronic passports, and various contactless payment cards. The subsequent process of the smart card module is pressed into the thin card. Therefore, the total thickness of the smart card module is generally less than 0.40mm. The total thickness of most smart card modules is now within 0.30mm. [0003] After the smart card module has undergone chip welding, gold wire ball welding and mold packaging, in order to perform electrical performance tests, it is necessary to punch out short-circuit holes on the metals that are originally connected to each other—usually called the process of punching short-circuit holes, so that It is an essential and...
