[0031] The position adjustment structure 3 includes a lifting seat 301, a scale plate 302, a worm 303, a first threaded screw 304, a translation platform 305, a second threaded screw 306 and a spring rod 307. The lifting seat 301 is slidably connected to the inner side of the guide frame 2, and a scale plate 302 is provided on the front side of the lifting seat 301. The lifting seat 301 is internally rotatably connected to the worm 303. Rotating the worm 303 drives the first threaded screw 304 to rotate. The lifting seat 301 is internally rotatably connected to the first threaded screw 304. The first threaded screw 304 is externally threadedly connected to the translation platform 305. The first threaded screw 304 drives the translation platform 305 to move left and right. The translation platform 305 is internally rotatably connected to the second threaded screw 306. When the second threaded screw 306 is rotated, the slide drives the punching head 6 to move forward and backward. The translation platform 305 is internally fixedly connected to the spring rod 307.
[0032] The positioning structure 4 includes a positioning plate 401, an eccentric wheel 402, a guide screw rod 403 and a clamp seat 404. The top of the punching table 1 is fixedly connected to the positioning plate 401, the top of the punching table 1 is rotatably connected to the eccentric wheel 402, the eccentric wheel 402 drives the connecting rod to eccentrically rotate, the top of the punching table 1 is fixedly connected to the guide screw rod 403, the connecting rod drives the clamp seat 404 to slide on the guide screw rod 403, the outside of the guide screw rod 403 is slidably connected to the clamp seat 404, and the connecting rod drives the clamp seat 404 to slide on the guide screw rod 403.
[0033] according to Figure 1 As shown, the guide frame 2 is composed of a top plate and four guide columns. The left and right sides of the lifting seat 301 slide up and down on the outside of the four guide columns through sliders. The four guide columns can play the role of guiding support. The hydraulic press 5 drives the hydraulic push rod at the bottom, and uses the hydraulic push rod to push the lifting seat 301 up and down to adjust the spacing height between the punching head 6 and the PCB board below.
[0034] according to Figure 3 and Figure 4 as well as Figure 5 As shown, the outer sides of the left ends of the two first threaded screws 304 are meshed with the outer sides of the worm 303 through the worm gear shaft, and the first hand wheel is rotated to drive the worm 303, so that the two first threaded screws 304 rotate synchronously, and the translation stage 305 is driven to move left and right. Since a pointer piece is fixed on the front side of the translation stage 305, the pointer piece slides on the front side of the scale plate 302, so that the moving distance of the translation stage 305 can be checked conveniently, and the position of the punching head 6 in the left and right direction can be adjusted.

[0036] according to Figure 1 and Figure 2 as well as Figure 8As shown, the reduction motor drives one of the sprocket rods, and the four sprocket rods are synchronously driven through the chain belts. The four sprocket rods synchronously drive four eccentric wheels 402, and the four eccentric wheels 402 respectively drive four connecting rods to rotate eccentrically, and one end of the four connecting rods is respectively rotatably connected to the top of four clamp seats 404. When the connecting rods rotate eccentrically, the four clamp seats 404 can be driven to slide and dock along the guide screw rod 403 to one side of the positioning disk 401. A damper and a rubber pad are fixed to the clamp seat 404 facing the side of the positioning disk 401, which can provide flexible support for the PCB board on the positioning disk 401.
[0037] according to Figure 1 and Figure 2 As shown, four groove structures are provided on the positioning plate 401, and the four grooves are distributed in a circular array and correspond one by one to the four clamp seats 404. The chip collecting box 7 is connected through the empty grooves, so that the dust generated by punching can be collected on the drawer plate through the empty grooves for easy removal and cleaning.
[0038] To summarize, the automated punching equipment first rotates the worm 303, and through the worm 303 engaging the worm wheel shaft, the two first threaded screws 304 synchronously drive the translation stage 305 to move left and right, and adjust the punching position in the left and right directions. Then, the second threaded screw 306 is rotated, and the slide table is used to drive the punching head 6 to move forward and backward, and adjust the punching position in the front and back directions. The sprocket rod is driven by the reduction motor, and the four sprocket rods synchronously drive the four eccentric wheels 402. The eccentric wheels 402 are connected to the top of the clamp seat 404 through the connecting rod. When the connecting rod rotates eccentrically, the four clamp seats 404 are respectively connected to the positioning disk 401 along the guide screw 403, so as to clamp and fix the PCB boards of different sizes on the positioning disk 401, thereby solving the problem that the automated punching equipment in the above-mentioned background technology is inconvenient to adjust the punching position and cannot adapt to clamping PCB boards of different sizes.
