[0028] The stamping mechanism 5 includes a support plate 501 located on the upper rear side of the support platform 3. An upper L-shaped plate 502 is installed on the upper front side of the support plate 501. A motor 503 is installed on the upper end of the upper L-shaped plate 502. A lead screw 504 is connected to the output end of the motor 503. A platform seat 505 is threaded onto the external thread of the lead screw 504.

A stamping head 511 is connected to the output end of the stamping cylinder 510.

[0029] The upper end of the stamping base 6 is provided with a positioning groove 29 that matches the terminal. The positioning groove 29 at the upper end of the stamping base 6 matches the terminal, which can ensure the accurate positioning of the terminal during stamping and improve the stamping quality.

[0030] Working principle:

[0031] Release process of stamping seat 6:

[0032] When the lifting cylinder 26 extends upward, the support plate 27 is driven to move upward. The upward movement of the support plate 27 drives the second support seat 28 to move upward, which in turn pushes the V-shaped swing arm 20 upward. With the cooperation of the connecting shaft 19 and the V-groove 21, the V-shaped swing arm 20 drives the lower pressure block 24 to swing away from the stamping seat 6.

[0033] As the pallet 27 moves upward, it gradually contacts the contact block 15 and pushes the contact block 15 upward, thereby pushing the L-shaped swing arm 9 to rotate around the connection of the first support seat 8. At this time, the spring 18 is compressed and the side stop block 12 on the L-shaped swing arm 9 disengages from the side wall of the stamping seat 6.

[0034] By releasing the lower pressure block 24 from the upper end of the stamping seat 6 and the side stop block 12 from the side wall of the stamping seat 6, the fixing of the stamping seat 6 is released, thereby making it easy to remove and replace the stamping seat 6 with different positioning grooves 29.

[0035] The process of fixing the stamping base 6:

[0036] When the stamping seat 6 is replaced, the lifting cylinder 26 retracts downward and the support plate 27 moves downward. During the downward movement of the support plate 27, under the elastic force of the spring 18, the L-shaped swing arm 9 gradually swings back around the first support seat 8, so that the side block 12 abuts against the side wall of the stamping seat 6.

[0037] The pallet 27 continues to move downward, causing the second support seat 28 to move downward, which in turn causes the V-shaped swing arm 20 to swing back until one side of the V-shaped groove 21 is vertical. As the lifting cylinder 26 continues to retract, the V-shaped groove 21 moves vertically downward along the outside of the connecting shaft 19. At this time, the V-shaped swing arm 20 causes the lower pressure block 24 to press down and tighten the stamping seat 6, thus completing the fixing of the stamping seat 6.

[0038] Stamping process:

[0039] Height adjustment: The stamping mechanism 5 drives the lead screw 504 to rotate through the motor 503, thereby driving the platform base 505 to move up and down. The up and down movement of the platform base 505 is transmitted to the mounting plate 509 through the fixed plate 506 and the guide rod 507, thereby adjusting the position of the stamping cylinder 510. This design allows the stamping head 511 to be precisely adjusted according to the terminals of different heights, improving the versatility and flexibility of the equipment.

[0040] Stamping action: After the stamping head 511 is adjusted to the appropriate position, the output end of the stamping cylinder 510 pushes the stamping head 511 downward to perform a stamping operation on the terminal placed on the stamping seat 6. After the stamping is completed, the stamping cylinder 510 drives the stamping head 511 back to the initial position to complete one stamping cycle.
