Description

Technical Field

[0001] This utility model relates to the technical field of tempered glass film polishing machine equipment, and in particular to a turntable lifting mechanism for a microcrystalline tempered glass film polishing machine. Background Technology

[0002] Tempered glass screen protectors, as a type of mobile phone protective film, possess excellent wear resistance and are very hard, thus providing excellent protection for the phone screen. Tempered glass is actually a type of prestressed glass. To improve the strength of the glass, chemical or physical methods are typically used to create compressive stress on the glass surface. When the glass is subjected to external forces, this surface stress is first offset, thereby improving its load-bearing capacity and enhancing its resistance to wind pressure, temperature changes, and impacts.

[0003] To ensure a better fit between the microcrystalline tempered glass screen protector and the phone screen, a polishing machine is typically used during production to smooth out any burrs around the screen. Existing polishing machines on the market use a lifting cylinder to bring the microcrystalline tempered glass, fixed to a tray, into contact with a polishing disc. The disc then polishes the screen. However, the lifting cylinder struggles to precisely adjust the tray position according to the varying thickness of the microcrystalline tempered glass, leading to poor contact and insufficient polishing, thus affecting the overall production quality. Utility Model Content

However, when the lifting cylinder adjusts the position of the tray, it is difficult to make precise fine adjustments according to the different thicknesses of the microcrystalline tempered glass film, resulting in poor contact and insufficient polishing of the microcrystalline tempered glass film during polishing.

[0005] To achieve the above objectives, this application provides the following technical solution: a turntable lifting mechanism for a microcrystalline tempered glass film polishing machine, comprising a U-shaped base and a spring. Four guide rods are fixed between the upper and lower inner walls of the U-shaped base. A carrier is slidably sleeved on the outside of the four guide rods.

A negative pressure fixing component is provided on the carrier, which is used to hold the microcrystalline tempered glass film. An installation component is provided on the U-shaped seat, which is used to install and fix the U-shaped seat on the polishing machine.

[0006] Furthermore, the negative pressure fixing assembly includes a shaft, one end of which is mounted on a U-shaped seat, and the other end of which is fixed with an air cylinder. The bottom of the air cylinder is fixedly connected to a suction cup.

[0007] Furthermore, a fixing plate is fixed to the outer wall of the air cylinder, and a second electric push rod is provided on the top of the fixing plate.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Example: Reference Figure 1-5 The illustrated rotary table lifting mechanism for a microcrystalline tempered glass film polishing machine includes a U-shaped base 1 and a spring 6. Four guide rods 2 are fixed between the upper and lower inner walls of the U-shaped base 1. A carrier 3 is slidably sleeved on the outside of the four guide rods 2. A first electric push rod 4 is provided on the top of the guide rod 2. A carrier block 5 is fixedly installed at the output end of the first electric push rod 4. End plates 7 are fixed to both the upper and lower ends of the spring 6. A pressure sensor is provided between the carrier block 5 and the upper end plate 7. The lower end plate 7 is fixedly installed on the top of the carrier 3. A pressure sensor is fixed to the lower surface of the upper end plate 7. Positioning rod 8, with a limiting cylinder 9 fixed on the upper surface of the lower end plate 7. The bottom end of the limiting rod 8 is inserted into the interior of the limiting cylinder 9, and the limiting rod 8 slides against the inner wall of the limiting cylinder 9. Two sliding rods 10 are fixed on the limiting rod 8. The limiting cylinder 9 has a sliding groove 11 for sliding the sliding rods 10. The spring 6 is sleeved on the outside of the limiting cylinder 9. A negative pressure fixing component is provided on the carrier 3. The negative pressure fixing component is used to hold the microcrystalline tempered film. An installation component is provided on the U-shaped seat 1. The installation component is used to install and fix the U-shaped seat 1 on the polishing machine.

[0024] The first electric push rod 4 pushes the carrier 3 to pull the microcrystalline tempered glass film fixed on the negative pressure fixing component toward the grinding disc. The drive of the first electric push rod 4 can force the spring 6 into a compressed state. With the help of the pressure sensor and the controller, the pressure applied by the first electric push rod 4 to the carrier 3 can be controlled, so that the microcrystalline tempered glass film pushed by the first electric push rod 4 can make full contact with the grinding disc and better complete the grinding process. The four guide rods 2 can prevent the carrier 3 from shifting its position when moving longitudinally, and ensure the stability of the movement direction of the microcrystalline tempered glass film. With the cooperation of the slide rod 10 and the slide groove 11, the limit rod 8 and the limit cylinder 9 can be prevented from completely separating.

[0025] The negative pressure fixing assembly includes a shaft 12, one end of which is mounted on a U-shaped seat 1, and the other end of which is fixed to an air cylinder 13. A suction cup 14 is fixedly connected to the bottom of the air cylinder 13. A fixing plate 15 is fixed to the outer wall of the air cylinder 13. A second electric push rod 16 is mounted on the top of the fixing plate 15. A support rod 17 is fixedly installed at the output end of the second electric push rod 16. A piston 18 is fixed to the bottom end of the support rod 17. The piston 18 slides in cooperation with the inner wall of the air cylinder 13. A through hole for the support rod 17 to slide is opened at the top of the air cylinder 13.

[0026] With the help of the second electric push rod 16, the support rod 17 and the piston 18 at its bottom end are moved longitudinally, so that after the microcrystalline tempered glass film is attached to the bottom of the suction cup 14, the piston 18 can adjust the air pressure inside the suction cup 14 to achieve the adsorption and fixation of the microcrystalline tempered glass film by the suction cup 14.

[0027] The mounting assembly includes a mounting plate 19, which is fixedly mounted on a U-shaped base 1. A pre-reserved groove 20 is provided on the left side of the mounting plate 19. The front and rear inner walls of the pre-reserved groove 20 are rotatably connected to a lead screw 21 via bearings. A first bevel gear 22 is fixed to the other end of the lead screw 21. A clamping plate 23 is threaded onto the lead screw 21. The clamping plate 23 slides in contact with the inner wall of the pre-reserved groove 20. A rotating rod 24 is provided through the top of the mounting plate 19. The joint between the mounting plate 19 and the rotating rod 24 is rotatably connected via bearings. A second bevel gear 25 is fixed to the bottom end of the rotating rod 24. The second bevel gear 25 meshes with both first bevel gears 22. A hexagonal plate 26 is fixed to the top end of the rotating rod 24. A bolt 27 is threaded onto the hexagonal plate 26. The bolt 27 is used to lock the positions of the mounting plate 19 and the hexagonal plate 26.

[0028] Using a wrench to turn the hexagonal plate 26, the hexagonal plate 26 drives the second bevel gear 25 to rotate. The second bevel gear 25 meshes with the two first bevel gears 22, which can drive the two lead screws 21 to rotate. The two lead screws 21 adjust the distance between the two clamping plates 23 by lead screw transmission, so that the two clamping plates 23 and the mounting plate 19 can be fixed in the designated position on the polishing machine. Using a wrench to turn the bolt 27, it locks the mounting plate 19 and the hexagonal plate 26, preventing the hexagonal plate 26 from continuing to rotate, and ensuring the secure installation of the mounting plate 19 on the polishing machine.

[0029] The working principle of this practical application is as follows:

[0030] In use, the two clamping plates 23 are clamped onto the polishing machine, and the mounting plate 19 is tightly fitted to the polishing machine. The hexagonal plate 26 is turned with a wrench, so that the hexagonal plate 26 pulls the second bevel gear 25 to rotate via the rotating rod 24. The second bevel gear 25 meshes with the two first bevel gears 22, so it can drive the lead screw 21 on the first bevel gear 22 to rotate. The two lead screws 21 pull the two clamping plates 23 together in a lead screw drive manner, clamping the polishing machine to complete the fixation of this mechanism on the polishing machine. In order to ensure the stability of the distance between the two clamping plates 23, the bolt 27 can be turned with a wrench, so that the bolt 27 locks the position of the mounting plate 19 and the hexagonal plate 26, preventing the hexagonal plate 26 from continuing to rotate.

[0031] After the microcrystalline tempered glass film is attached to the bottom of the suction cup 14, the second electric push rod 16 is retracted, causing the second electric push rod 16 to pull the piston 18 upward with the support rod 17. After the piston 18 moves upward, it can force the air pressure inside the suction cup 14 to drop, so that the suction cup 14 can hold the microcrystalline tempered glass film. The first electric push rod 4 pushes the carrier 3 to pull the microcrystalline tempered glass film closer to the grinding disc. When the microcrystalline tempered glass film is attached to the grinding disc, the first electric push rod 4 continues to extend, which can force the spring 6 to be in a compressed state. With the help of a pressure sensor and a controller, the pressure applied by the first electric push rod 4 to the carrier 3 can be controlled within a suitable range, so that the microcrystalline tempered glass film pushed by the first electric push rod 4 can be in full contact with the grinding disc. In this way, the grinding disc can be used to effectively polish the microcrystalline tempered glass film.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
