These holes are used to install brackets, hooks or other display accessories to ensure the functionality and aesthetics of the display rack. Compared with traditional drilling methods, laser drilling has higher precision and less material waste. According to the design requirements of the display rack, the hole diameter, hole position and depth of the punching system can be flexibly adjusted.

A liquid supply box 9 is fixedly connected to the upper end, a liquid guide tube 10 is fixedly connected between the auxiliary component 83 and the liquid supply box 9, and the collecting box 12 is fixedly installed in the processing table 1. A pair of dust removal grooves 11 are opened at the upper end of the processing table 1, and the dust removal grooves 11 are communicated with the collecting box 12. A pair of limiting slides are opened at the upper end of the processing table 1, and the pair of limiting slides are located outside the pair of dust removal grooves 11. The fixed component 13 is slidably connected in the pair of limiting slides. A plurality of control buttons 14 are fixedly connected to the front end of the processing table 1. A pair of load-bearing plates 4 are controlled by a pair of sizing screws 3, and the horizontal control plate 5 is moved up and down together, and the longitudinal control plate 6 drives the multi-functional drill bit 8 to move accordingly. The drilling position of the multi-functional drill bit 8 is controlled by the horizontal control plate 5 and the longitudinal control plate 6 respectively. Before drilling and grinding, the fixing component 13 is used to press and fix the plate, and the waste chips under drilling and grinding fall into the dust removal groove 11 and are recovered by the collecting box 12 for centralized treatment.

[0032] The detection assembly 82 includes a detection carrier ring 821, an annular groove is provided at the middle outer end of the metal drill bit 81, the detection carrier ring 821 is slidably connected in the annular groove, a plurality of marking blocks 822 are provided in the middle of the detection carrier ring 821, a liquid storage ring 823 is slidably connected to the inner end of the detection carrier ring 821 close to the annular groove, a receiving groove is provided at one end of the liquid storage ring 823 close to the marking block 822, an inflatable bag 824 is fixedly connected to the end of the liquid storage ring 823 away from the marking block 822, and the inflatable bag 824 is fixedly connected in the annular groove The inflatable bag 824 is fixedly connected to one end away from the liquid storage ring 823 with a magnetic sheet ring 825. After the detection carrier ring 821 is punched, the detection component 82 is moved to the hole position, and the marking block 822 is used to detect the uneven protrusions on the inner wall of the hole. The inflatable bag 824 is inflated to push the liquid storage ring 823 and drive the detection carrier ring 821 and the overall marking block 822 to fit tightly against the inner wall of the hole. The marking block 822 marks the uneven protrusions. Both the detection carrier ring 821 and the liquid storage ring 823 are easily deformed rubber plates.

[0033] The marking block 822 includes a hexagonal block 8221, which is arranged in the middle of the detection carrier ring 821. A through hole is opened in the middle of the hexagonal block 8221. A marking cotton 8222 is fixedly connected to one end of the hexagonal block 8221 away from the liquid storage ring 823.

[0034] The marking block 822 also includes a micro-rod 8223, which is fixedly connected to the inner wall of the accommodating groove. A sealing block 8224 is fixedly connected to one end of the micro-rod 8223 close to the hexagonal block 8221, and the sealing block 8224 is located in the perforation. The hexagonal block 8221 is pulled and supported by the micro-rod 8223 and the sealing block 8224 to prevent the marking block 8222 from being thrown out under the action of the centrifugal force of rotation. At the same time, the sealing block 8224 can be used to seal the side of the perforation away from the marking cotton 8222 to reduce liquid seepage from the perforation.

[0035] The marking block 822 also includes a same-sex magnetic ring piece 8225, which is embedded in the end of the hexagonal block 8221 away from the marking cotton 8222, and the same-sex magnetic ring piece 8225 matches the magnetic ring 825. When the marking block 822 approaches the magnetic ring 825, the repulsive force between them can be used to make the marking block 822 be squeezed and moved to the accommodating groove, and then it can be reset under the action of magnetic force, and the repulsive force can be used to make the sealing block 8224 press against the inner wall of the perforation for sealing.

[0036] The marking block 822 also includes an auxiliary rubber ring 8226, which is fixedly connected to the outer end of the hexagonal block 8221 away from the marking cotton 8222. The auxiliary rubber ring 8226 can seal the gaps between the multiple marking blocks 822 to reduce liquid leakage. At the same time, after the marking block 822 slides close to the receiving groove, the auxiliary rubber ring 8226 bulges to block the gap to reduce liquid leakage.

[0037] The marking block 822 also includes liquid-conducting cotton 8227, which is disposed in the perforation and abuts against the marking cotton 8222. The marking liquid can be effectively absorbed by the liquid-conducting cotton 8227 and guided to the marking cotton 8222 for easy marking.

[0038] The auxiliary component 83 includes a driven ring 831, an annular groove is provided at the upper outer end of the metal drill bit 81, and the driven ring 831 is rotatably connected in the annular groove. A plurality of connecting holes are provided in the middle of the metal drill bit 81, and the connecting holes are respectively connected with the annular groove and the annular groove. The driven ring 831 rotates in the annular groove, so that the catheter 10 can maintain a stable state to prevent it from being knotted, so that the liquid supply box 9 can drain the marking liquid from the catheter 10 to the inside of the annular groove, and the marking liquid flows from the connecting hole to the receiving groove.

[0039] The auxiliary component 83 also includes a pair of auxiliary arc rings 832, which are fixedly connected to the upper and lower ends of the driven ring 831. The inner wall of the annular slide groove is provided with a pair of grooves matching the auxiliary arc rings 832. The auxiliary arc rings 832 can not only assist the sliding of the driven ring 831, but also play an auxiliary sealing role to prevent liquid leakage.

[0040] The fixing assembly 13 includes a pair of lifting plates 131, and the pair of lifting plates 131 are respectively slidably connected in the limiting slide grooves, and a lower pressure plate 132 is fixedly connected between the pair of lifting plates 131. A plurality of anti-slip particles 133 are fixedly connected to the lower end of the lower pressure plate 132. The lifting plates 131 are contracted to drive the lower pressure plate 132 to press down to compact the plate, and under the action of the plurality of anti-slip particles 133, the friction between the lower pressure plate 132 and the plate can be effectively increased to improve the stability of the compaction.

[0041] Working principle:

[0042] Place the plate on the display rack on the upper end of the processing table 1, then move the fixing component 13 to a suitable position, control the lifting plate 131 to shrink so that the lower pressing plate 132 presses down to compact the plate, then control a pair of sizing screws 3 to rotate to move the multifunctional drill bit 8 downward, and control the horizontal control board 5 and the longitudinal control board 6 to adjust the position of the multifunctional drill bit 8 to punch holes. After the hole is punched by the metal drill bit 81, continue to move the multifunctional drill bit 8 downward so that the detection component 82 is located in the middle of the hole, and use the inflatable bag 824 to inflate and push the liquid storage ring 823 and the detection carrier ring 821, so that the marking block 822 is against the inner wall of the hole. If there is a bulge and unevenness, the bulge squeezes the single marking block 822 so that the marking block 8 22 slides to the receiving groove, and at the same time, the sealing block 8224 squeezes the liquid-conducting cotton 8227 to make room for the perforation, and the marking liquid flows from the liquid-conducting tube 10 into the annular slide groove, and then flows into the receiving groove from the connecting hole, and finally the marking liquid enters the perforation of the marking block 822 that slides into the receiving groove, so that the marking liquid is absorbed and guided by the liquid-conducting cotton 8227 and adsorbed in the marking cotton 8222, and then the marking cotton 8222 marks the protrusions. The staff can directly obtain the uneven position by observing the marks, and then perform secondary grinding. Subsequently, after the magnetic sheet ring 825 is deflated, the detection carrier ring 821 and the liquid storage ring 823 are reset, and at the same time, the sliding marking block 822 resets and slides under the magnetic repulsion of the magnetic sheet ring 825.

[0043] It can be seen from the above technical solutions that the present invention has the following beneficial effects:

[0044] After the multifunctional drill bit 8 is used to drill holes in the plate, the detection component 82 is used to detect and mark the holes. The inflatable bag 824 is inflated to push the liquid storage ring 823 and the detection carrier ring 821, so that the marking block 822 is against the inner wall of the hole. The marking block 822 is used to detect uneven protrusions in the hole. The single marking block 822 is squeezed at the protrusions to make the marking block 822 slide to the receiving groove, and the marking liquid enters the perforation of the marking block 822 and marks it, so that the staff can directly observe the uneven position, which is not only convenient for the grinding of the rounded inner angle, but also greatly improves the processing efficiency of the plate.
