[0002] The phone cover is an important component of the phone casing. It usually refers to the plastic sheet covering the top of the phone. It not only protects the battery area from external scratches and damage, but also enhances the overall aesthetics of the phone.

[0003] During the polishing process of mobile phone cover plates, positioning fixtures are required to fix them in place. However, the vibration generated during polishing may cause the cover plates to shift. In addition, if the clamping strength is too high, it may damage the cover plates during the limiting process. Furthermore, a lot of debris is generated during the polishing process, which is difficult to clean up when it falls onto the worktable. Therefore, a positioning fixture for polishing mobile phone cover plates is needed. This fixture uses the displacement of a movable rod to create a negative pressure suction operation on the cover plates using suction cups. This can stabilize the cover plates, prevent them from shifting during polishing, and avoid damage caused by high-strength clamping. It also collects the debris generated during polishing, improving overall work efficiency. Utility Model Content

[0022] In the following description, embodiments of the positioning fixture for grinding mobile phone cover plates according to the present invention will be described with reference to the accompanying drawings.

[0023] Figure 1-6This invention illustrates a positioning fixture for grinding mobile phone cover plates according to an embodiment of the present invention. It includes a worktable 1, a positioning plate 2 fixedly mounted at one end of the worktable 1, and a drive box 3 fixedly mounted inside the positioning plate 2. A second pulley 23 is provided on one side of a first steel cable 8, and the second pulley 23 is rotatably connected to the positioning plate 2. A first pulley 20 is provided on one side of a second steel cable 10, and the first pulley 20 is rotatably connected to the positioning plate 2. By setting the second pulley 23 and the first pulley 20, the friction between the first steel cable 8 and the second steel cable 10 can be reduced during movement, and the direction of the force generated can be adjusted during the pulling process. The restrictions further facilitate smooth overall movement. A rotating shaft 4 is mounted on one side of the drive box 3, and a gear 5 is fixedly mounted on the other side of the rotating shaft 4. A placement groove 17 is opened at one end of the positioning plate 2, and a sealed hole 18 is opened at one end inside the placement groove 17. A suction cup 12 is fixedly installed inside the placement groove 17, and one end of the suction cup 12 communicates with the sealed hole 18. The suction cup 12 is made of rubber. By setting the suction cup 12, it can better fit the collection cover. At the same time, the rubber material can increase friction to prevent displacement, and the adsorption effect can be more effective. A movable rod 6 is movably installed inside the sealed hole 18. One end of the movable rod 6... A toothed plate 7 is fixedly installed. First baffles 9 are movably installed at both ends of the worktable 1, and a first steel cable 8 is installed on one side of each baffle 9. A collection groove 13 is provided inside the worktable 1, cooperating with the first baffle 9 and also with a second baffle 11. The collection groove 13 provides a space for storing grinding debris, preventing it from scattering randomly and making collection more convenient. The first baffle 9 is connected to the movable rod 6 via the first steel cable 8. Second baffles 11 are movably installed on both sides of the positioning plate 2, and a second steel cable 10 is installed on one side of each second baffle 11. The baffle 11 is connected to the movable rod 6 by a second steel cable 10, and a first spring 19 is installed on one side of the second baffle 11. The two sets of second baffles 11 are connected by the first spring 19. Limit blocks 21 are fixedly installed on both sides of the first baffle 9, and a second spring 22 is installed on one side of the limit block 21. Grooves that cooperate with the limit blocks 21 are opened on both sides of the worktable 1, and the limit blocks 21 are connected to the worktable 1 by the second spring 22. By setting the limit blocks 21, the movement of the first baffle 9 can be limited, ensuring that the first baffle 9 will not deviate during the movement, so that the overall device operates stably.

[0024] Working principle: When using this utility model, the user starts the drive box 3 to drive the rotating shaft 4 to rotate. When the rotating shaft 4 rotates, it drives the gear 5 to rotate, thereby causing the gear plate 7 to move down. When the gear plate 7 moves down, it drives the movable rod 6 to move down. When the movable rod 6 moves down, it pulls the second steel cable 10 and the first steel cable 8 down. At this time, the second baffle 11 and the first baffle 9 retract under the tension, so that the second baffle 11 and the first baffle 9, which were originally blocked, gradually open the collection groove 13. At the same time, when the movable rod 6 moves down, the mobile phone cover is placed above the positioning plate 2. At this time, the suction cup 12 and the mobile phone... With the cover plate in place, and the openings of the sealed hole 18 and the suction cup 12 at one end blocked by the phone cover plate, the downward movement of the movable rod 6 creates a negative pressure state inside the sealed hole 18. At the same time, the phone cover plate is attracted by the suction cup 12, allowing for polishing. The polishing debris falls into the collection groove 13, causing the rotating shaft 4 to reverse. The second baffle 11 resets under the action of the first spring 19, and the first baffle 9 resets under the action of the second spring 22. At this point, the collection groove 13 closes again. Starting the fan 14 drives the air duct 15 to evacuate the inside of the collection groove 13 to collect the debris.

[0025] In summary, this positioning fixture for polishing mobile phone covers utilizes a movable rod 6. When the movable rod 6 moves downward, it creates negative pressure inside the sealed hole 18, simultaneously facilitating suction from the suction cup 12. The downward movement of the movable rod 6 also causes the first baffle 9 and the second baffle 11 to retract, opening the collection groove 13. During polishing, debris falls into the collection groove 13, effectively securing the mobile phone cover using the suction cup. This method facilitates fixation while avoiding damage to the cover from clamping, and also allows for easy debris collection and cleaning.
