[0001] This utility model relates to the field of mobile phone glass cover processing, specifically a mobile phone glass cover processing fixture. Background Technology

[0002] The manufacturing process of mobile phone glass covers requires CNC precision carving, polishing, coating and other processes. During the polishing of the front and back of the mobile phone glass cover, a clamp is needed to hold and fix the mobile phone glass cover.

[0003] A Chinese patent with authorization announcement number CN 219275628 U discloses a fixture for processing mobile phone glass covers, belonging to the field of fixture technology. It includes a mounting box with multiple first and second electric telescopic rods symmetrically mounted on both sides. First and second connecting rods are respectively mounted on the output ends of the first and second electric telescopic rods. A sleeve is fixedly mounted on the top of each connecting rod, and a rotating shaft is rotatably mounted inside the sleeve. A locking screw is threaded onto the sleeve, and a pad is fixedly mounted on one end of the sleeve. This invention, through the arrangement of the sleeve, locking screw, and rotating shaft, allows the locking screw to be loosened and the rotating shaft rotated during use, thereby flipping the mobile phone glass cover clamped between two pads. During the flipping process, the mobile phone cover does not need to be removed and reinstalled, improving production efficiency. Furthermore, the multiple first and second electric telescopic rods allow for the simultaneous clamping of multiple mobile phone glass covers.

[0004] Existing fixtures, when used in auxiliary polishing devices to clamp and fix mobile phone glass covers, typically employ vacuum adsorption to hold and fix the thin glass covers, which makes it difficult to quickly unload the glass covers, resulting in low unloading efficiency. Therefore, a new mobile phone glass cover processing fixture is proposed to address this issue. Utility Model Content

A mobile phone glass cover is placed in the placement groove, and multiple suction holes are opened on the bottom plate of the placement groove. A cavity is opened inside the placement seat, and a filter screen is installed on the inner wall of the cavity. A feeding assembly is installed on the placement seat, and the feeding assembly includes a plate groove. A plate groove is opened on the placement seat, and a flipping plate is rotatably installed on the inner wall of the plate groove via a rotating shaft. A vacuum pump is mounted on the support frame via a base. The vacuum pump is equipped with a first exhaust pipe and a second exhaust pipe. The other end of the first exhaust pipe is connected to the placement seat and extends into the cavity. A vent pipe is installed on the side wall of the placement seat. Solenoid valves are installed on the vent pipe and the first exhaust pipe. By flipping the flip plate, the flip plate rotates around the pivot. During the flipping process, the mobile phone glass cover in the placement slot is lifted up, and then the mobile phone glass cover is removed, realizing the rapid unloading of the mobile phone glass cover. This structure ensures the positioning accuracy of the mobile phone glass cover by setting a placement slot adapted to the size of the mobile phone glass cover. At the same time, the unloading component is set to quickly unload the mobile phone glass cover, which is beneficial to improving the unloading efficiency of the mobile phone glass cover.

[0007] Preferably, two fixed plates are mounted on the polishing table, a guide rod is fixedly mounted between the two fixed plates, and a lead screw is rotatably mounted between the two fixed plates. A stepper motor is mounted on the side wall of one of the fixed plates via a base, and the output shaft of the stepper motor is fixedly connected to the lead screw.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0019] Please see Figure 1-3As shown, a mobile phone glass cover plate 6 processing fixture includes a polishing table 1, a support frame 2 mounted on the bottom side of the polishing table 1, a PLC controller 3 mounted on the side wall of the polishing table 1, and a clamping assembly mounted on the polishing table 1. The clamping assembly includes a placement seat 4, which is fixedly mounted on the polishing table 1 by a mounting plate. The placement seat 4 has a placement groove 401, in which a mobile phone glass cover plate 6 is placed. The bottom plate of the placement groove 401 has multiple adsorption holes 402. A cavity 403 is formed inside the placement seat 4, and a filter screen 404 is installed on the inner wall of the cavity 403. A feeding assembly is mounted on the placement seat 4, and the feeding assembly includes a plate groove 5. The placement seat 4 has a plate groove 5, and a flipping plate 501 is rotatably mounted on the inner wall of the plate groove 5 via a rotating shaft. A vacuum pump 405 is mounted on the support frame 2 via a base, and a first exhaust pipe 406 and a second exhaust pipe 405 are mounted on the vacuum pump 405. 7. The other end of the first exhaust pipe 406 is connected to the placement seat 4 and extends into the cavity 403. A vent pipe 408 is installed on the side wall of the placement seat 4. Solenoid valves are installed on the vent pipe 408 and the first exhaust pipe 406. During operation, the existing fixtures use vacuum adsorption to clamp and fix the mobile phone glass cover plate 6 in the process of the auxiliary polishing device. Because the mobile phone glass cover plate 6 is relatively thin, it is usually clamped and fixed by vacuum adsorption. However, it is difficult to quickly unload the mobile phone glass cover plate 6, resulting in low unloading efficiency. By placing the mobile phone glass cover plate 6 in the placement groove 401 of the placement seat 4, the placement groove 401 matches the size of the mobile phone glass cover plate 6. Therefore, this fixture is only suitable for one specification of mobile phone glass cover plate 6. Placing the mobile phone glass cover plate 6 in the placement groove 401 can ensure positioning accuracy. The upper surface of the mobile phone glass cover plate 6 is higher than the upper surface of the placement seat 4.

[0020] When clamping and fixing the mobile phone glass cover 6, the vacuum pump 405 is controlled by the PLC controller 3. The vacuum pump 405 is an Edwards nXDS15i. The vacuum pump 405 draws the cavity 403 into a vacuum through the first exhaust pipe 406, and a negative pressure is generated at the adsorption hole 402. There is a pressure difference with the outside. Under the action of the pressure difference, the multiple adsorption holes 402 adsorb and position the mobile phone glass cover 6, thereby achieving the clamping and fixing of the mobile phone glass cover 6 and ensuring that the mobile phone glass cover 6 does not shift during the polishing process.

[0021] During the polishing process of the mobile phone glass cover 6, the front is polished first, then the mobile phone glass cover 6 is flipped over, and then the back is polished. During the flipping and unloading process of the mobile phone glass cover 6, the vacuum pump 405 stops operating, and then the PLC controller 3 controls the solenoid valve on the vent pipe 408 to open, the vacuum in the cavity 403 is released, and the adsorption force at the adsorption hole 402 disappears, realizing the release of the mobile phone glass cover 6. Then the operator flips the flipping plate 501, which rotates around the pivot. During the flipping process, the flipping plate 501 lifts the mobile phone glass cover 6 in the placement slot 401, and then removes the mobile phone glass cover 6, realizing the rapid unloading of the mobile phone glass cover 6. This structure, by setting the placement slot 401 adapted to the size of the mobile phone glass cover 6, ensures the positioning accuracy of the mobile phone glass cover 6. At the same time, the unloading component is set up to quickly unload the mobile phone glass cover 6, which helps to improve the unloading efficiency of the mobile phone glass cover 6.

[0022] Please see Figure 4-5As shown, two fixed plates 7 are installed on the polishing table 1. A guide rod 701 is fixedly installed between the two fixed plates 7, and a lead screw is rotatably installed between the two fixed plates 7. A stepper motor 702 is installed on the side wall of one of the fixed plates 7 via a base. The output shaft of the stepper motor 702 is fixedly connected to the lead screw. A slider 703 is sleeved on the guide rod 701 and the lead screw. Two nylon telescopic sleeves 704 are installed around the lead screw. The nylon telescopic sleeves 704 are installed on the side wall of the slider 703 and the side wall of the fixed plate 7. A dust collection hopper 8 is installed on the slider 703, and a dust collection hose 801 is installed on the dust collection hopper 8. A dust collection box 802 is installed at the other end of 801. The dust collection box 802 is mounted on the support frame 2. A dust collection box 803 is placed inside the dust collection box 802. A handle is installed on the outer wall of the dust collection box 803. A filter plate is installed on the side wall of the dust collection box 803. An exhaust box 804 is installed on the side wall of the dust collection box 802. Exhaust slots 805 are opened on the two side walls of the exhaust box 804 and the side wall of the dust collection box 802. A drive motor 806 is installed inside the exhaust box 804 via a base. A rotor is installed on the output shaft of the drive motor 806. Fan blades 807 are installed on the rotor. During operation, the existing fixture is used with the auxiliary polishing device to handle... During the clamping and fixing of the glass cover plate 6, debris easily adheres to the clamp, making it difficult to clean quickly and resulting in poor cleanliness. After the upper surface of the glass cover plate 6 is polished by the polishing device, the dust collection bucket 8 performs dust collection on the entire placement base 4. Specifically, the PLC controller 3 controls the stepper motor 702 to operate, driving the lead screw to rotate. The lead screw drives the slider 703 on it to move horizontally on the lead screw and guide rod 701, and the slider 703 drives the dust collection bucket 8 to move horizontally. At the same time, the PLC controller 3 controls the drive motor 806 to operate, driving the rotor to rotate at high speed. The fan blades 807 rotate at high speed, causing the air inside the exhaust box 804, dust collection box 802, suction hose 801, and dust collection hopper 8 to be discharged from the exhaust channel 805. There is a pressure difference between the exhaust box 804, dust collection box 802, suction hose 801, and dust collection hopper 8 and the outside. Under the action of the pressure difference, the debris and air are sucked into the dust collection hopper 8 together, and then enter the dust collection box 803 of the dust collection box 802 from the suction hose 801. The debris is intercepted by the filter plate on the side wall of the dust collection box 803, and the clean air is discharged from the exhaust channel 805, thus cleaning the debris on the placement seat 4 and the mobile phone glass cover 6.

[0023] Afterwards, the phone glass cover 6 is removed, and the PLC controller 3 controls the stepper motor 702 to operate again, driving the dust collection bucket 8 to move horizontally in the opposite direction to clean the placement seat 4 and placement slot 401 again. The bottom of the suction hole 402 has a filter screen 404, so debris will not enter the cavity 403. After cleaning the placement seat 4 and placement slot 401, the phone glass cover 6 is put back into the placement slot 401. Then, the back of the phone glass cover 6 is polished. Then, the above steps are repeated to clean the debris on the placement seat 4 and phone glass cover 6. Afterwards, the phone glass cover 6 is removed, and the placement seat 4 and placement slot 401 are cleaned again. This structure can quickly clean the debris on the fixture, which helps to improve the cleanliness of the fixture.

[0024] Working principle: Existing fixtures, during the clamping and fixing of the mobile phone glass cover 6 by the auxiliary polishing device, typically use vacuum adsorption to clamp and fix the thin mobile phone glass cover 6. However, this makes it difficult to quickly unload the mobile phone glass cover 6, resulting in low unloading efficiency. By placing the mobile phone glass cover 6 into the placement groove 401 of the placement base 4, the placement groove 401 is matched to the size of the mobile phone glass cover 6. Therefore, this fixture is only suitable for one specification of mobile phone glass cover 6. Placing the mobile phone glass cover 6 in the placement groove 401 can ensure positioning accuracy. The upper surface of the mobile phone glass cover 6 is higher than the upper surface of the placement base 4. When clamping and fixing the mobile phone glass cover 6, the vacuum pump 405 is controlled by the PLC controller 3. The vacuum pump 405 is an Edwards model. In the nXDS15i, vacuum pump 405 evacuates cavity 403 to a vacuum level through first exhaust pipe 406, creating negative pressure at adsorption holes 402. This creates a pressure difference with the outside environment. Under this pressure difference, multiple adsorption holes 402 adsorb and position the mobile phone glass cover 6, achieving clamping and fixing, ensuring no displacement of the mobile phone glass cover 6 during polishing. During polishing, the front is polished first, then the back is polished after flipping the cover. During the flipping and unloading process, vacuum pump 405 stops operating, and PLC controller 3 opens the solenoid valve on vent pipe 408, releasing the vacuum in cavity 403. The adsorption force at adsorption holes 402 disappears, releasing the mobile phone glass cover 6. Then, the operator flips the flipping plate 501, which rotates around the axis. During the flipping process, the placement slot... The mobile phone glass cover 6 inside 401 is lifted up, and then the mobile phone glass cover 6 is removed, realizing the rapid unloading of the mobile phone glass cover 6. This structure ensures the positioning accuracy of the mobile phone glass cover 6 by setting a placement slot 401 that is adapted to the size of the mobile phone glass cover 6. At the same time, the unloading component is set to unload the mobile phone glass cover 6 quickly, which helps to improve the unloading efficiency of the mobile phone glass cover 6. During the process of clamping and fixing the mobile phone glass cover 6 by the auxiliary polishing device, the existing clamps are prone to the adhesion of debris, which is difficult to clean quickly, resulting in poor cleanliness of the clamps. After the upper surface of the mobile phone glass cover 6 is polished by the polishing device, the dust collection bucket 8 performs dust collection treatment on the entire placement seat 4. That is, the PLC controller 3 controls the stepper motor 702 to operate, which drives the lead screw to rotate. The lead screw drives the slider 703 on it to move horizontally on the lead screw and guide rod 701. The slider 703 drives the dust collection bucket 8 to move horizontally.Simultaneously, the PLC controller 3 controls the drive motor 806 to operate, driving the rotor to rotate at high speed. The rotor drives the fan blades 807 to rotate at high speed, causing the air inside the exhaust box 804, dust collection box 802, suction hose 801, and dust collection hopper 8 to be discharged from the exhaust channel 805. A pressure difference exists between the exhaust box 804, dust collection box 802, suction hose 801, and dust collection hopper 8 and the outside environment. Under the action of this pressure difference, debris and air are sucked into the dust collection hopper 8, and then enter the dust collection box 803 of the dust collection box 802 through the suction hose 801. The debris is intercepted by the filter plate on the side wall of the dust collection box 803, and clean air is discharged from the exhaust channel 805, thus cleaning the debris on the placement seat 4 and the mobile phone glass cover 6. Afterwards, the mobile phone glass cover 6 can be removed. The PLC controller 3 controls the stepper motor 702 to operate again, driving the dust collection bucket 8 to move horizontally in the opposite direction, and to clean the placement seat 4 and placement slot 401 again. The bottom of the suction hole 402 has a filter screen 404, so debris will not enter the cavity 403. After cleaning the placement seat 4 and placement slot 401, the mobile phone glass cover 6 is placed back into the placement slot 401. Then, the back of the mobile phone glass cover 6 is polished. The above steps are repeated to clean the debris on the placement seat 4 and mobile phone glass cover 6. Afterwards, the mobile phone glass cover 6 is removed, and the placement seat 4 and placement slot 401 are cleaned again. This structure can quickly clean debris from the fixture, improving the cleanliness of the fixture.
