[0047] For a better understanding of the present utility model, the following will, in conjunction with Figure 1 - Figure 9 describe in detail the working principle of the technical solution of the present utility model:

[0048] During use, the cold-shrinkable finger sleeve 1 is injection-molded through the injection molding unit 100. By controlling the first rotation driving member 150, the first rotation driving member 150 can drive the injection molding table 120 to rotate, so that the injection-molded cold-shrinkable finger sleeve 1 is rotated to the side of the upper mold 140. Then, by controlling the moving unit 300, the first clamping unit 400 is moved to directly above the injection-molded cold-shrinkable finger sleeve 1. Then, the sleeve 410 is sleeved on the cold-shrinkable finger sleeve 1, so that the three finger tubes of the cold-shrinkable finger sleeve 1 are respectively located in the corresponding second receiving cavities 412, and the sleeve of the cold-shrinkable finger sleeve 1 is located in the first receiving cavity 411. Then, by controlling the fastening driving assembly, the fastening driving assembly can drive the three fastening blocks 430 to move closer to each other, and the three fastening blocks 430 and the corresponding fixed shafts 420 clamp the three finger tubes of the cold-shrinkable finger sleeve 1 to fix the cold-shrinkable finger sleeve 1. Then, by controlling the moving unit 300, the first clamping unit 400 is moved to directly above the first camera 220, and the bottom surface of the cold-shrinkable finger sleeve 1 is photographed by the first camera 220. Then, by controlling the moving unit 300, the first clamping unit 400 is moved to directly above a certain placement table 240 and drives the cold-shrinkable finger sleeve 1 to move to directly above a certain placement table 240. The cold-shrinkable finger sleeve 1 is sleeved on the placement table 240. By controlling the clamping driving assembly 530, the clamping driving assembly 530 can drive one end of the two clamping claws 520 to rotate, so that the other ends of the two clamping claws 520 move closer to each other to clamp the cold-shrinkable finger sleeve 1. Then, by controlling the fastening driving assembly, the fastening driving assembly can drive the three fastening blocks 430 to separate from each other, and the three fastening blocks 430 and the corresponding fixed shafts 420 release the three finger tubes of the cold-shrinkable finger sleeve 1. By controlling the moving unit 300, the first clamping unit 400 moves upward, so that the cold-shrinkable finger sleeve 1 can be placed on the placement table 240. As the detection table 210 rotates, the cold-shrinkable finger sleeve 1 reaches the second camera 220. When the cold-shrinkable finger sleeve 1 rotates to the position of the second camera 220, the detection table 210 stops rotating. By controlling the second telescopic driving member 275, the second telescopic driving member 275 can drive the moving seat 272 to move towards the detection table 210 until the driving gear 273 meshes with the driven gear 271 that reaches the position of the second camera 220. Then, by controlling the third rotation driving member 274, the third rotation driving member 274 can drive the driving gear 273 to rotate, thereby driving the engaged driven gear 271 to rotate, and further driving the corresponding placement table 240 to rotate. The cold-shrinkable finger sleeve 1 will rotate accordingly, so that the second camera 220 can comprehensively photograph the side surface of the cold-shrinkable finger sleeve 1. When the second camera 220 finishes photographing the side surface of the cold-shrinkable finger sleeve 1,The driving gear 273 is separated from the driven gear 271 that reaches the second camera 220, and the inspection table 210 continues to rotate. The cold-shrinkable finger sleeve 1 reaches the third camera 220, and the top surface of the cold-shrinkable finger sleeve 1 can be photographed through the third camera 220. After the photographing is completed, if there are defects, the cold-shrinkable finger sleeve 1 is placed in the defective product recycling bin, and if there are no defects, the cold-shrinkable finger sleeve 1 is placed in the qualified product recycling bin. This cold-shrinkable finger sleeve production system integrates the injection molding, collection, and inspection of the cold-shrinkable finger sleeve 1, can realize the injection molding, collection, and inspection of the cold-shrinkable finger sleeve 1, and no longer requires manual inspection of the appearance of the injection-molded cold-shrinkable finger sleeve 1, reducing the labor intensity of workers.

[0050] (1) Cover the sleeve 410 on the cold-shrinkable finger sleeve 1, so that the three finger tubes of the cold-shrinkable finger sleeve 1 are respectively located in the corresponding second receiving cavities 412, and the sleeve of the cold-shrinkable finger sleeve 1 is located in the first receiving cavity 411. Then, by controlling the fastening drive assembly, the fastening drive assembly can drive the three fastening blocks 430 to close together, and the three fastening blocks 430 and the corresponding fixed shafts 420 clamp the three finger tubes of the cold-shrinkable finger sleeve 1 to realize the fixation of the cold-shrinkable finger sleeve 1;

[0051] (2) When the cold-shrinkable finger sleeve 1 rotates to the second camera 220, the inspection table 210 stops rotating. By controlling the second telescopic drive member 275, the second telescopic drive member 275 can drive the moving seat 272 to move towards the inspection table 210 until the driving gear 273 meshes with the driven gear 271 that reaches the second camera 220. Then, by controlling the third rotation drive member 274, the third rotation drive member 274 can drive the driving gear 273 to rotate, thereby driving the meshing driven gear 271 to rotate, and further driving the corresponding placement table 240 to rotate. The cold-shrinkable finger sleeve 1 will rotate accordingly, so that the second camera 220 can comprehensively photograph the side of the cold-shrinkable finger sleeve 1;

[0052] (3) This cold-shrinkable finger sleeve production system integrates the injection molding, collection, and inspection of the cold-shrinkable finger sleeve 1, can realize the injection molding, collection, and inspection of the cold-shrinkable finger sleeve 1, and no longer requires manual inspection of the appearance of the injection-molded cold-shrinkable finger sleeve 1, reducing the labor intensity of workers.
