Both ends of the positioning rod 507 penetrate through the positioning block 506 and are installed in the chute opened on the surface of the processing table 1. The push plate 501 is arranged in a T-shaped structure, so that it can facilitate the staff to take out the PCB board heat sink 7 after trimming and stamping, further improving the working efficiency of trimming and stamping of the PCB board heat sink 7, avoiding the need for manual operation to take out the PCB board heat sink 7 after trimming and stamping, improving the overall convenience of the device, and facilitating the staff to operate and use.

[0030] Embodiment 2:

[0031] Please refer to Figure 1-7, in this embodiment, the driving component 6 includes a foot pedal 601, a driving rod 602, a crank handle rod 603, a worm gear 604, a worm 605, a connecting rod 606, a synchronous pulley 607, and a synchronous belt 608. The surface of the processing table 1 is rotatably connected with the foot pedal 601. The surface of the foot pedal 601 is hinged with the driving rod 602. The surface of the processing table 1 is rotatably connected with the crank handle rod 603. The crank handle rod 603 is rotatably connected with the driving rod 602. The surface of the crank handle rod 603 is provided with the worm 605. The surface of the processing table 1 is rotatably connected with the connecting rod 606. The surface of the connecting rod 606 is provided with the worm gear 604. The worm 605 is meshed with the worm gear 604. The surfaces of the connecting rod 606 and the rotating rod 505 are both provided with the synchronous pulley 607. The synchronous belt 608 is wound between the two synchronous pulleys 607. The surface of one side of the foot pedal 601 is rotatably connected with a support rod 609. The support rod 609 is rotatably connected to the surface of the crank handle rod 603. Thus, it enables the staff to step on the foot pedal with one foot to take out the PCB heat sink 7, and prepare the next PCB heat sink 7 to be trimmed and stamped with the hand on the other side, avoiding manual removal of the PCB heat sink 7 after trimming and stamping by the staff, reducing the labor intensity of the staff, and further improving the work efficiency of the staff. Figure 7 The left side in shows the schematic diagram before processing the PCB heat sink 7. Figure 7 The right side in shows the schematic diagram after processing the PCB heat sink 7.

[0032] Workflow: When using the stamping mechanism 2, after the trimming of the PCB heat sink is completed, the operator steps on the foot pedal 601. At this time, the foot pedal 601 drives the drive rod 602 to move. During the movement of the drive rod 602, it pushes the crank handle rod 603 to rotate. The crank handle rod 603 and the foot pedal 601 are supported by the support rod 609, which can improve the connectivity between the crank handle rod 603 and the foot pedal 601 and prevent them from disengaging during use, affecting the normal operation of the device. During the rotation of the crank handle rod 603, it drives the worm 605 to rotate on the surface of the processing table 1. Since the worm 605 meshes with the worm gear 604, the worm 605 drives the worm gear 604 to rotate during its rotation. During the rotation of the worm gear 604, it drives the connecting rod 606 to rotate. Since the worm 605 and the worm gear 604 have a self-locking property, the foot pedal 601 can be self-locked to prevent the foot pedal 601 from moving when not in use. During the rotation of the connecting rod 606, it drives the synchronous pulley 607 to rotate. At this time, the synchronous pulley 607 drives the synchronous belt 608 to move, driving the rotating rod 505 to rotate. This enables the operator to step on the pedal with one foot to take out the PCB heat sink while preparing the next PCB heat sink 7 for trimming and stamping with the other hand, avoiding manual removal of the trimmed and stamped PCB heat sink 7 by the operator, reducing the labor intensity of the operator, and further improving the work efficiency of the operator.

[0033] When the rotating rod 505 rotates, the rotating rod 505 drives the connecting plate 504 to rotate. During the rotation of the connecting plate 504, it drives the adjusting knob 503 to rotate. At this time, the adjusting knob 503 slides inside the adjusting plate 502. During the sliding process of the adjusting knob 503 inside the adjusting plate 502, it pushes the adjusting plate 502 to move. At this time, the adjusting plate 502 drives the push plate 501 to move. During the movement of the push plate 501, the adjusting plate 502 drives the positioning block 506 to slide on the positioning rod 507 in the chute opened on the surface of the processing table 1. The positioning rod 507 and the positioning block 506 can position and guide the movement position of the push plate 501 to prevent the push plate 501 from shifting during movement. During the movement of the push plate 501, it pushes out the trimmed and stamped PCB heat sink 7 on the stamping lower plate 4, and then slides down along the slope on the processing table 1 and disengages, enabling the operator to conveniently take out the trimmed and stamped PCB heat sink 7, further improving the work efficiency of trimming and stamping the PCB heat sink 7, avoiding manual operation to take out the PCB heat sink 7 after trimming and stamping, improving the overall convenience of the device, and facilitating the operator's operation and use.

[0034] The embodiments of the present utility model have been described in detail above in conjunction with the accompanying drawings. However, the present utility model is not limited to the above embodiments, and various changes can be made without departing from the gist of the present utility model within the scope of knowledge possessed by those skilled in the art.
