[0022] The present invention will now be further described in detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are simplified schematic diagrams that only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0023] Reference Figure 1 and Figure 2 As shown, the utility model provides a technical solution: a punching device for preparing high-precision multi-layer circuit boards, comprising an operating table 1, an extension plate 2 is fixedly connected to the top of the operating table 1, a punching body 3 is installed at the front end of the extension plate 2, two partitions 4 are fixedly connected to the top of the operating table 1, a cleaning plate 5 is installed on the top of the operating table 1, an embedded handle 6 is provided at the front end of the cleaning plate 5, a collecting groove 7 is provided on the top of the operating table 1, a through groove 8 is provided on the right side of the operating table 1, a collecting basket 9 is slidably connected inside the through groove 8, and a handle 10 is fixedly connected to the right side of the collecting basket 9. After the staff stops using the punching body 3, they move the cleaning plate 5 so that the cleaning plate 5 can clean the waste generated after the processing of the top of the operating table 1 is completed, so that the waste is put into the collecting groove 7 provided on the top of the operating table 1 under the push of the cleaning plate 5, so as to avoid the waste from accumulating in the punching area and affecting the subsequent punching operation.

[0024] Reference Figure 1 and Figure 3 As shown, in this embodiment: the front end of the operating table 1 is fixedly connected with a U-shaped block 11, the interior of the U-shaped block 11 is fixedly connected with a rotating shaft 12, the surface of the rotating shaft 12 is rotatably connected with a clamping plate 13, and a clamping groove 14 is provided on the top of the cleaning plate 5. The staff pushes the cleaning plate 5 to the rear end of the top of the operating table 1, and then pushes the clamping plate 13 downward to make the clamping plate 13 and the clamping groove 14 provided on the top of the cleaning plate 5 abut against each other, thereby fixing the cleaning plate 5 to prevent the punching machine body 3 from colliding with the cleaning plate 5 during operation.

[0025] Reference Figure 3As shown, in this embodiment: the rear end of the clamping plate 13 is fixedly connected with a tension spring 15, and the rear end of the tension spring 15 is fixedly connected to the inside of the U-shaped block 11. By setting the tension spring 15, the tension spring 15 will drive the clamping plate 13 to shrink toward the inside of the U-shaped block 11 through its own elastic force, so that the clamping plate 13 is more stable when it abuts against each other in the clamping groove 14.

[0026] Reference Figure 4 As shown, in the present embodiment: a slot 16 is provided on the inner wall of the partition 4, a limiting rod 17 is fixedly connected inside the slot 16, a limiting hole 18 is provided at one end of the cleaning plate 5, the inside of the limiting hole 18 is slidably connected to the surface of the limiting rod 17, and through the mutual cooperation between the limiting rod 17 and the limiting hole 18, the movement trajectory of the cleaning plate 5 can be guided to avoid deviation during the movement.

[0027] Reference Figure 1 As shown, in this embodiment: the cleaning plate 5 is made of polyurethane material, and the polyurethane material also has good wear resistance and corrosion resistance, which makes the polyurethane cleaning plate 5 not easy to wear during long-term use and can resist the erosion of various corrosive substances, thereby extending its service life.

[0028] Reference Figure 6 As shown, in this embodiment: an extension block 22 is fixedly connected to the right side of the operating table 1, a threaded hole 21 is provided at one end of the handle 10, a round hole 23 is provided at one end of the extension block 22, and a threaded rod 24 is slidably connected inside the round hole 23. The staff rotates the threaded rod 24 so that the threaded rod 24 passes through the extension block 22 and is twisted into the threaded hole 21 provided at one end of the handle 10 to fix the collection basket 9, thereby preventing the collection basket 9 from sliding or shaking during use.

[0029] Reference Figure 5 As shown, in this embodiment: both ends of the inner cavity of the collecting tank 7 are fixedly connected with sliders 20, and both ends of the collecting basket 9 are provided with slide grooves 19. By setting the slide grooves 19 and the sliders 20, the collecting basket 9 can be pulled out stably to avoid the internal waste from spilling due to shaking.

[0030] Working principle: After the staff stops using the punching machine body 3, they then move the cleaning plate 5 so that the cleaning plate 5 can clean the waste generated after the processing on the top of the operating table 1 is completed, and the waste is pushed by the cleaning plate 5 and placed in the collecting groove 7 opened on the top of the operating table 1 to avoid the waste from accumulating in the punching area and affecting the subsequent punching operation. The staff pushes the cleaning plate 5 to the rear end of the top of the operating table 1, and then pushes the clamping plate 13 downward so that the clamping plate 13 and the clamping groove 14 opened on the top of the cleaning plate 5 abut against each other, fixes the cleaning plate 5, and avoids the punching machine body 3 from colliding with the cleaning plate 5 during operation. By setting the tension spring 15, the tension spring 15 will drive the clamping plate 13 to retract toward the inside of the U-shaped block 11 through its own elastic force, so that the clamping plate 1 3 is that the card slots 14 are more stable when they abut against each other. Through the cooperation between the limiting rod 17 and the limiting hole 18, the movement trajectory of the cleaning plate 5 can be guided to avoid deviation during the movement. The polyurethane material also has good wear resistance and corrosion resistance, which makes the polyurethane cleaning plate 5 not easy to wear during long-term use and can resist the erosion of various corrosive substances, thereby extending its service life. The staff rotates the threaded rod 24 to make the threaded rod 24 pass through the extension block 22 and twist it into the threaded hole 21 opened at one end of the handle 10 to fix the collection basket 9. In case the collection basket 9 slides or shakes during use, the slide groove 19 and the slider 20 are provided to enable the collection basket 9 to be pulled out stably to avoid the internal waste from spilling due to shaking.
