[0002] The chip and card in the IC card are usually pressed together by hot melt adhesive through a hot welding head packaging, especially used in embedded packaging of one card with four cores. The waste generated after the chip and card in the IC card are packaged is usually divided into two types: chip waste and card base waste. IC card waste needs to be classified by separating the chip from the card base.
[0003] In the prior art, the chip and the card base of the IC card waste are usually separated by a blade. This method of separating the card base and the chip is closely bonded to the card base by hot melt adhesive, and the blade is easy to slip when removing the core, which may cause safety hazards such as cutting fingers.
[0004] Therefore, it is necessary to develop a coring device to improve the convenience of coring and reduce safety hazards. Utility Model Content
[0005] The utility model aims to provide a core removal device to solve the problem of difficulty in separating a chip and a card base in an existing IC card, which poses a potential safety hazard.
[0006] In order to solve the above technical problems, the utility model provides a coring device, including a workbench and a coring assembly, wherein the coring assembly includes a heat welding positioning block arranged on the workbench, a heat welding head slidably connected to the heat welding positioning block, a driving member for driving the heat welding head to slide relative to the heat welding positioning block in a direction approaching and away from the workbench, and an elastic member with one end fixed on the heat welding positioning block, the other end of the elastic member is fixed on the heat welding head, and the axial direction of the elastic member is parallel to the moving direction of the heat welding head.
[0007] Optionally, a card positioning block is also included for limiting the position of the IC card on the workbench.
[0008] Optionally, the card positioning block includes a first limiting bar and a second limiting bar, the first limiting bar is perpendicular to the second limiting bar, and the first limiting bar and the second limiting bar are arranged on the workbench.
[0009] Optionally, the thermal welding head includes a welding head body and a heating tube, and the welding head body is covered on the heating tube.
[0010] Optionally, a thermocouple is also included, and the thermocouple is arranged on the welding head body.
[0011] Optionally, it also includes a temperature controller connected to the thermocouple and used to control the temperature of the heating tube according to temperature information measured by the thermocouple.
[0012] Optionally, the driving member includes a slide groove and a pin shaft, the driving member is rotatably connected to the heat welding positioning block, the pin shaft is connected to the heat welding head, and the pin shaft is slidably connected to the slide groove.
[0013] Optionally, the thermal welding positioning block includes a positioning body and a mounting plate, wherein the mounting plate is fixedly connected to the positioning body, and the mounting plate is fixedly connected to the workbench.
[0014] Optionally, the mounting plate has a cross groove.
[0015] Optionally, there are two coring assemblies, and the two coring assemblies are arranged opposite to each other.
[0016] The utility model provides a coring device, which has the following beneficial effects:
[0017] Since the heat welding positioning block is arranged on the workbench, the heat welding head is slidably connected with the heat welding positioning block, and the driving member is used to drive the heat welding head to slide relative to the heat welding positioning block in the direction of approaching and moving away from the workbench. Therefore, the heat welding head can be slid on the heat welding positioning block by operating the driving member, and the sliding direction is approaching or moving away from the workbench. In this way, when the heat welding head approaches the workbench under the drive of the driving member, part of the hot melt adhesive connecting the card base and the chip of the IC card arranged on the workbench can be melted off. When the heat welding head is driven away from the workbench by the driving member, the IC card can be held and the card base and the chip of the IC card can be separated, so as to achieve the purpose of convenient core removal and reduce safety hazards. Since one end of the elastic member is fixed on the heat welding positioning block and the other end is fixed on the heat welding head, the axial direction of the elastic member is parallel to the moving direction of the heat welding head. Therefore, when the driving member is not operated, the heat welding head can be kept at a certain distance from the workbench through the stretching or compression effect of the elastic member, thereby avoiding the heat welding head from damaging the workbench when coring is not required, and the safety of the coring device can be improved.
