[0035] The collecting mechanism includes a collecting box 45, which is located below the drill bit 40. An opening is provided at the upper end of the collecting box 45. A filter screen 46 is installed inside the collecting box 45. A scraper 47 is slidably installed on the collecting box 45.

Discharge troughs are provided on both sides of the collecting box 45, and waste boxes 52 are fixedly installed on both sides of the collecting box 45.

[0036] Working principle: fix the glass cover plate 3 to be processed on the support plate 4. Specifically, since a support tube 5 is installed on the support plate 4, the glass cover plate 3 is first placed on the support tube 5, so that there will be a gap between the glass cover plate 3 and the support plate 4. When the cam 7 is in the state of being moved, the cam 7 is in the state of being moved along the axis of the cam 7 and the cam 7 is in the state of being moved along the axis of the cam 7. When the cam 7 is in the state of being moved, the cam 7 is in the state of being moved along the axis of the cam 7 and the cam 7 is in the state of being moved along the axis of the cam 7.

[0037] After the glass cover plate 3 is fixed, the glass cover plate 3 can be transported to the bottom of the drill bit 40. Specifically, the extended end of the cylinder 37 is retracted, so that the motor seat and the lifting motor 36 on the motor seat move downward together, and the short rod 38 plays a guiding role. The lifting motor 36 moving downward moves downward together with the driving gear 29 fixed on the output shaft of the lifting motor 36, so that the driving gear 29 is meshed with the intermediate gear 28 rotatably mounted on the bottom plate 1. At this time, the driving gear 29 leaves the lifting gear 30, and the lifting motor 36 is started. The driving gear 29 is driven to rotate through the output shaft of the lifting motor 36, and the driving gear 29 is driven to rotate. The wheel 29 is meshed with the intermediate gear 28, so the intermediate gear 28 will rotate, and the intermediate gear 28 is meshed with the transposition gear 27 fixedly mounted on the rotating shaft 21, so the transposition gear 27 and the rotating shaft 21 will also rotate. The gear groove 20 provided on the support rod 19 provides an installation position for the transposition gear 27. The rotating rotating shaft 21 drives the rotating drum 17 to rotate relative to the fixed drum 18, so that the rotating drum 17 will move and rotate with the support plate 4. In this process, the guide wheel 16 slides along the lower end of the fixed drum 18. When the guide wheel 16 slides between the guide groove 25 and the limit frame 24, it is first located in the arc A guide wheel 16 on one side of the plate 15 will slide into between the limit frame 24 and the guide groove 25, and the other guide wheel 16 has not yet slid in. Then, the connecting frame 14 installed on the rotating drum 17 will turn over with the arc plate 15 and the guide wheel 16. The guide groove 25 and the connecting frame 14 are symmetrical structures, so the connecting frame 14 will turn over 180 degrees. In this way, after turning over, the support plate 4 is located above the glass cover plate 3, that is, the glass cover plate 3 is located between the support plate 4 and the bottom plate 1. At this time, the positioning hole 26 reserved on the support plate 4 will be located on the side close to the drill bit 40, and then the flipped support plate 4 and the glass cover plate 3 move It reaches directly below the drill bit 40, and the end of the support plate 4 away from the rotating cylinder 17 falls on two symmetrically arranged vertical plates 53. The function of the vertical plates 53 is to support the support plate 4 to prevent the glass cover plate 3 and the support plate 4 from being deformed due to pressure when the drill bit 40 is drilling. The pressure means that if there is no support at the end of the support plate 3 away from the rotating cylinder 17, then the support plate 4 will only have one supporting point at the connection with the rotating cylinder 17, and the support plate 4 will form a "cantilever beam". In this way, when the support plate 4 and the glass cover plate 3 are subjected to the pressure of the drill bit 40, the end of the support plate 4 away from the rotating cylinder 17 will be subjected to uneven force.

[0038] After the glass cover plate 3 and the support plate 4 are in place, the cylinder 37 is started again, so that the extended end of the cylinder 37 pushes the lifting motor 36 and the driving gear 29 upwards, and the driving gear 29 is meshed with the lifting gear 30, and the lifting motor 36 is started, so that the lifting motor 36 drives the driving gear 29 to rotate, and then the driving gear 29 will drive the lifting gear 30 to rotate, and the belt assembly 31 that forms a pulley with the lifting gear 30 will rotate together, so that the lead screw 32 rotates. It should be noted that the belt assembly 31 includes two pulleys and a belt, and the two pulleys are connected to the lifting gear 30 and the lead screw 32 respectively, and the two pulleys are connected by the belt. Since the lifting plate 33 is threadedly matched with the lead screw 32, and the lifting plate 33 is slidably matched with the vertical guide rod 34, the lifting plate 33 will slide downward along the vertical guide rod 34 during the rotation of the lead screw 32, and the vertical guide rod 34 is stretched at this time. The function of the vertical guide rod 34 is to assist the lifting plate 33 to reset.

[0039] When the lifting plate 33 moves downward, the drilling motor 39 will move downward. The drilling motor 39 will be started so that the output shaft of the drilling motor 39 will drive the drill bit 40 to rotate. The drill bit 40 moving downward will pass through the positioning hole 26 and start drilling the glass cover plate 3. The positioning hole 26 is used to limit the drill bit 40 to prevent the drill bit 40 from deflecting. In this way, the support plate 4 and the positioning hole 26 on the support plate 4 can effectively provide the drilling accuracy of the drill bit 40.

[0040] During the descent of the lifting plate 33, the lifting plate 33 moves downward together with the right-angle rod 41, and the right-angle rod 41 pushes the pressure plate 42 downward, causing the pressure plate 42 to move downward along the inner wall of the water tank 43. In this way, the cold water in the water tank 43 is pressed into the water pipe 54, so that the water is sprayed onto the drill bit 40 from the other end of the water pipe 54, thereby cooling the drill bit 40. It should be noted that since a one-way valve is provided at one end of the water pipe 55 close to the water tank 43, water can only flow into the water pipe 54 from the one-way valve provided on the water pipe 54 during the downward movement of the pressure plate 42.

[0041] During the rotation of the screw 32, the cylindrical gear 2 51 fixed on the screw 32 will also rotate, and then the cylindrical gear 1 50 meshing with the cylindrical gear 2 51 will rotate, so that the cylindrical gear 1 50 drives the connecting rod 2 49 to rotate, and the connecting rod 2 49 pulls the connecting rod 1 48, so that the connecting rod 1 48 pulls the scraper 47 to slide back and forth on the collecting box 45. The part of the scraper 47 extending into the collecting box 45 is located above the filter screen 46, so the moving scraper 47 will push the waste chips that fall on the filter screen 46 when the drill bit 40 drills a hole back and forth to the discharge trough on the collecting box 45, and fall from the discharge trough into the waste box 52. At the same time, the cooled water will also fall to the bottom of the collecting box 45. After the work is completed, the water collected in the collecting box 45 can be added to the water tank 2 44. Of course, the collecting box 45 and the water tank 2 44 can also be connected by a pipe so that the water flows into the water tank 2 44. This is conceivable for technicians in this field.

[0042] After the drilling of the glass cover plate 3 is completed, the lifting motor 36 is reversed to lift the lifting plate 33 upward and reset. During the upward movement of the lifting plate 33, the lifting plate 33 will move upward with the right-angle rod 41 and the pressure plate 42, so that the water in the water tank 2 44 can be pumped into the water tank 1 43 through the water pipe 2 55. Of course, the water in the water tank 2 44 can also be pumped into the water tank 1 43 by setting a water pump to supplement the water in the water tank 1 43. This is conceivable for those skilled in the art.

[0043] After the lifting plate 33 is reset, the cylinder 37 is started again, so that the lifting motor 36 drives the driving gear 29 to descend to mesh with the intermediate gear 28, and then the lifting motor 36 is started, so that the lifting motor 36 drives the driving gear 29 to rotate again, and the driving gear 29 rotates the intermediate gear 28 and the shifting gear 27, so that the glass cover plate 3 after drilling will continue to rotate with the supporting plate 4, and then pass through another guide groove 25 and the limit frame 24 provided on the fixing cylinder 18, so that it will turn over 180 degrees again, so that after the drilling is completed The glass cover plate 3 returns to the top of the support plate 4 again. The purpose of this is that the support plate 4 and the glass cover plate 3 installed on the support plate 4 undergo two flips through the set limit frame 24 and the guide groove 25. One is used to flip the glass cover plate 3 installed on the support plate 4 to the bottom of the support plate 4, so that when drilling, the drill bit 40 can be limited by the positioning hole 26 on the support plate 4, and the other is used to flip the processed glass cover plate 3 so that the processed glass cover plate 3 returns to the top of the support plate 4, which is convenient for disassembly and loading and unloading. Of course, the purpose of setting two guide grooves 25 and limit frames 24 is that when the glass cover plate 3 is installed on the first support plate 4, the glass cover plate 3 on the second support plate 4 passes through the guide groove 25 and the limit frame 24 and flips to reach the bottom of the drill bit 40; the glass cover plate 3 on the third support plate 4 has passed through the drilling of the drill bit 40 and another limit frame 24 and guide groove 25, and enters a detachable state. Such an intermittent setting can greatly improve work efficiency.
