[0038] The following will describe the embodiments of the present utility model in conjunction with Figures 1 to 3 , it should be understood that the following description is only an illustrative embodiment of the present utility model and does not constitute any limitation to the present utility model.

[0039] Referring to Figures 1 to 3 , an embodiment of the present utility model provides a hot riveting tooling for blister CCS. The tooling includes bolts 100, pins 200, a loading and unloading platform 300, a base 400, and a transfer plate 500.

[0040] Among them, multiple bolts 100 can be provided. For example, the number of bolts 100 is four; multiple pins 200 can also be provided. For example, the number of pins 200 is four. Both can be evenly distributed on both sides of the base 400, enabling the base 400 to be more balanced in force.

[0041] The loading and unloading platform 300 is detachably arranged on the hot riveting machine and can be controlled to move in and out by a servo motor or a cylinder.

[0042] Bolting holes 410 and pin holes 420 are provided on the base 400.

[0043] The bolts 100 are matched with the bolting holes 410, and the pins 200 are matched with the pin holes 420. The bolts 100 pass through the bolting holes 410 and are connected to the loading and unloading platform 300, and the pins 200 pass through the pin holes 420 and are connected to the loading and unloading platform 300, which can fix the base 400 to the loading and unloading platform 300.

[0044] The transfer plate 500 is provided with limit blocks 510, which can fix the blister separator and prevent the blister separator from loosening. The transfer plate 500 is detachably arranged on the base 400. Four limit blocks 510 can be provided, and each limit block 510 can be evenly distributed at the four corners of the transfer plate 500, making the force on the blister CCS more balanced and improving the stability of the transfer plate 500 in fixing the blister CCS.

[0045] It can be understood that the hot riveting tooling for thermoforming CCS provided by the embodiments of the present utility model fixes the base 400 on the feeding and discharging platform 300 by arranging bolt positioning holes 410 and pin positioning holes 420 on the base 400, passing bolts 100 through the bolt positioning holes 410 to connect with the feeding and discharging platform 300, and passing pins 200 through the pin positioning holes 420 to connect with the feeding and discharging platform 300. Thus, even if the threads are worn, the pins 200 can limit the position of the base 400, avoiding the phenomenon of hot riveting deviation due to insufficient limitation of the base 400. Moreover, a transfer plate 500 is arranged and a limiting block 510 is arranged on the transfer plate 500 to fix the thermoforming isolation plate, which is convenient for taking and placing the thermoforming CCS and is not easily bent and deformed during production handling. The transfer plate 500 can stack materials offline, improving the efficiency of manual material stacking.

[0046] Specifically, in some embodiments of the present utility model, the transfer plate 500 is provided with transfer plate positioning holes 520, and the base 400 is provided with transfer plate positioning posts 430, and the transfer plate positioning holes 520 match the transfer plate positioning posts 430. When the transfer plate 500 is placed on the base 400, the transfer plate positioning posts 430 can pass through the transfer plate positioning holes 520 to limit the position of the transfer plate 500 and prevent the transfer plate 500 from sliding during the hot riveting process. Of course, the transfer plate positioning holes 520 and the transfer plate positioning posts 430 can also be in interference fit to prevent the transfer plate 500 from loosening.

[0047] Furthermore, to simplify the structure of the base 400, the transfer plate positioning posts 430 can also be integrally formed with the base 400. Of course, the transfer plate positioning posts 430 and the base 400 can also be in interference fit. For example, positioning post holes matching the transfer plate positioning posts 430 are arranged on the base 400, and the transfer plate positioning posts 430 are in interference fit with the positioning post holes, and the transfer plate positioning posts 430 can be fixed by being installed into the positioning post holes, which is convenient and fast.

[0048] In some embodiments of the present utility model, the transfer plate 500 is further provided with a handle 530. The handle 530 can be arranged on one side of the transfer plate 500. When the transfer plate 500 is placed on the base 400, the handle 530 protrudes from the edge of the base 400, facilitating the taking and placing of the transfer plate 500. Of course, the handle 530 can be integrally formed with the transfer plate 500, which can simplify the structure of the transfer plate 500 and facilitate manufacturing.

[0049] In some embodiments of the present utility model, the transfer plate 500 is further provided with thermoforming isolation plate groove limiting holes 540, which can avoid the aluminum bar grooves on the thermoforming isolation plate and limit the thermoforming isolation plate to further fix the thermoforming CCS.
