[0004] (1) Technical problems to be solved

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a multi-directional mobile phone cover edge grinding structure. This grinding structure aims to solve the technical problem that in the existing technology, after grinding one side of the mobile phone cover, it is necessary to remove and re-fix it in order to grind the other edge of the mobile phone cover. This process is time-consuming and results in low grinding efficiency of the mobile phone cover.

[0006] (2) Technical solution

[0007] To solve the above-mentioned technical problems, this utility model provides a multi-directional mobile phone cover edge grinding structure. The grinding structure includes a grinding table, a first drive motor, and a grinding wheel. The first drive motor is mounted on the upper surface of the grinding table, and the output end of the first drive motor is connected to the grinding wheel. A connecting block is connected to the upper surface of the grinding table, and a gantry slide is mounted on the side surface of the connecting block. A guide slider is connected to the side surface of the gantry slide, and a guide groove is formed on the side surface of the connecting block near the guide slider. The first drive motor is mounted on the surface of the gantry slide. A second telescopic rod is installed between the connecting block and the gantry slide. A bracket is connected to the upper surface of the grinding table, and a first bearing is fitted onto the surface of the bracket. A rotating rod is connected inside the first bearing, and a base is connected to the top of the rotating rod. A driven bevel gear is connected to the bottom of the rotating rod. A second drive motor is mounted on the side surface of the bracket, and the output end of the second drive motor is connected to a driving bevel gear. A second bearing is fitted onto the upper surface of the bracket, and a third telescopic rod is installed inside the second bearing. A pressure plate is connected to the telescopic end of the third telescopic rod.

[0008] When using the polishing structure of this technical solution, after the position of the phone cover is fixed, the second drive motor can drive the rotating rod to rotate through the active bevel gear and the driven bevel gear. The rotation of the rotating rod can drive the base to rotate, and the rotation of the base can drive the fixed phone cover to rotate. Through the pressure plate, the third telescopic rod rotates inside the second bearing. After the phone cover rotates 90°, the second telescopic rod controls the movement of the gantry slide to polish the other side.

[0009] Preferably, the guide slider is connected to the connecting block through the guide groove, and the gantry slide and the second telescopic rod form a lifting structure. The retraction of the second telescopic rod generates a pulling force on the gantry slide. The gantry slide being pulled can drive the guide slider to slide inside the guide groove, which can limit the movement direction of the gantry slide.

[0010] Furthermore, the rotating rod forms a rotating structure with the bracket through the first bearing, and the driving bevel gear and the driven bevel gear form a meshing structure. When the second drive motor runs, it can drive the driving bevel gear to rotate. The rotation of the driving bevel gear can drive the rotating rod to rotate through the driven bevel gear, and the rotation of the rotating rod can drive the base to rotate.

[0011] Furthermore, the third telescopic rod forms a rotating structure with the bracket through the second bearing, and a hydraulic lifting structure is formed between the pressure plate and the third telescopic rod. When the third telescopic rod is running, it can drive the pressure plate to move downward. When the pressure plate moves to the surface of the phone cover, the position of the phone cover can be fixed.

[0012] Furthermore, a machine tool gantry slide is installed on the upper surface of the grinding table, a vacuum suction cup is installed on the side surface of the machine tool gantry slide, a storage rack is connected to the upper surface of the grinding table, a guide rod is connected to the side surface of the storage rack, the guide rod passes through the inside of the side ear, a base plate is connected to the side surface of the side ear, a mobile phone cover plate is stacked on the upper surface of the base plate, and a first telescopic rod is connected between the base plate and the grinding table.

[0013] Furthermore, the guide rod and the side lug are symmetrically arranged on both sides of the base plate, and the guide rod and the side lug are slidably connected. When the base plate is subjected to force, the side lug can slide on the surface of the guide rod, which can limit the movement direction of the base plate.

[0014] Furthermore, a hydraulic lifting structure is formed between the base plate and the first telescopic rod. When the first telescopic rod extends, it can drive the base plate to move upward, and the upward movement of the base plate can drive the phone cover to move upward.

[0015] (3) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. In this utility model, when the third telescopic rod extends, it drives the pressure plate to move downward, thereby fixing the position of the phone cover. When the second drive motor runs, it can drive the active bevel gear to rotate. The rotation of the active bevel gear can drive the rotating rod to rotate through the driven bevel gear. The rotation of the rotating rod can drive the base to rotate. The rotation of the base can drive the fixed phone cover to rotate. Through the pressure plate, it drives the third telescopic rod to rotate inside the second bearing. After the phone cover rotates 90°, the second telescopic rod controls the movement of the gantry slide to polish the other side. This process is repeated to automatically polish the four edges, thereby achieving multi-directional edge polishing of the phone cover and improving polishing efficiency.

[0018] 2. In this utility model, the machine tool gantry slide moves the vacuum suction cup to the upper surface of the mobile phone cover. Then, the sliding seat of the machine tool gantry slide moves the vacuum suction cup downward and moves the hand on the top laterally. At this time, the first telescopic rod can be extended. When the first telescopic rod extends, it can drive the base plate to move upward. The upward movement of the base plate can drive the mobile phone cover to move upward. The height of the mobile phone cover is controlled by the thickness of the mobile phone cover. This makes it convenient to realize the loading operation of automatic grinding of the edge of the mobile phone cover. Attached Figure Description

The first drive motor 16 is mounted on the surface of the gantry carriage 12, and a second telescopic rod is installed between the connecting block 11 and the gantry carriage 12. 15. A bracket 17 is connected to the upper surface of the grinding table 1. A first bearing 18 is fitted onto the surface of the bracket 17. A rotating rod 19 is connected inside the first bearing 18. A base 20 is connected to the top of the rotating rod 19. A driven bevel gear 21 is connected to the bottom of the rotating rod 19. A second drive motor 22 is installed on the side surface of the bracket 17. A driving bevel gear 23 is connected to the output end of the second drive motor 22. A second bearing 24 is fitted onto the upper surface of the bracket 17. A third telescopic rod 25 is installed inside the second bearing 24. A pressure plate 26 is connected to the telescopic end of the third telescopic rod 25.

[0027] Among them, the guide slider 13 is connected to the connecting block 11 through the guide groove 14, the gantry carriage 12 and the second telescopic rod 15 form a lifting structure, the rotating rod 19 is connected to the bracket 17 through the first bearing 18 to form a rotating structure, the driving bevel gear 23 and the driven bevel gear 21 form a meshing structure, the third telescopic rod 25 is connected to the bracket 17 through the second bearing 24 to form a rotating structure, and the pressure plate 26 and the third telescopic rod 25 form a hydraulic lifting structure.

[0028] In addition, a machine tool gantry slide 2 is installed on the upper surface of the grinding table 1, a vacuum suction cup 3 is installed on the side surface of the machine tool gantry slide 2, a storage rack 5 is connected to the upper surface of the grinding table 1, a guide rod 6 is connected to the side surface of the storage rack 5, the guide rod 6 passes through the inside of the side ear 7, a base plate 8 is connected to the side surface of the side ear 7, a mobile phone cover plate 9 is stacked on the upper surface of the base plate 8, a first telescopic rod 10 is connected between the base plate 8 and the grinding table 1, the guide rod 6 and the side ear 7 are symmetrically arranged on both sides of the base plate 8, the guide rod 6 and the side ear 7 are slidably connected, and the base plate 8 and the first telescopic rod 10 form a hydraulic lifting structure.

[0029] Working principle: When using the device of this technical solution, the machine tool gantry slide 2 first drives the vacuum suction cup 3 to move to the upper surface of the mobile phone cover plate 9. Then, the sliding seat of the machine tool gantry slide 2 drives the vacuum suction cup 3 to move downward and move the hand on the top laterally. At this time, the first telescopic rod 10 can be extended. When the first telescopic rod 10 is extended, it can drive the base plate 8 to move upward. The upward movement of the base plate 8 can drive the mobile phone cover plate 9 to move upward, controlling the mobile phone cover plate 9 to move upward by a certain thickness.

[0030] When the sliding seat of the machine tool gantry slide 2 moves the phone cover 9 to the surface of the base 20 via the vacuum chuck 3, the vacuum chuck 3 can release the phone cover 9, allowing it to fall onto the surface of the base 20. When the sliding seat of the machine tool gantry slide 2 moves to the outside of the bracket 17, the third telescopic rod 25 moves and drives the pressure plate 26 downward. When the pressure plate 26 reaches the surface of the phone cover 9, the position of the phone cover 9 can be fixed. Then, the second telescopic rod 15 retracts, generating a pulling force on the gantry slide 12. The gantry slide 12, under this pulling force, can drive the guide slider 13 to slide inside the guide groove 14. When the sliding seat of the gantry slide 12 moves to the side surface of the phone cover 9 via the first drive motor 16, the first drive motor 16 drives the grinding wheel 4 to rotate, which can then grind the phone cover 9. The edges of the phone cover 9 are polished, and the sliding seat of the gantry slide 12 can drive the first drive motor 16 to move laterally, so that the edges of the phone cover 9 can be polished completely. Then, when the second telescopic rod 15 extends, it can drive the gantry slide 12 to reset. Then, the second drive motor 22 can be controlled to run. When the second drive motor 22 runs, it can drive the active bevel gear 23 to rotate. The rotation of the active bevel gear 23 can drive the rotating rod 19 to rotate through the driven bevel gear 21. The rotation of the rotating rod 19 can drive the base 20 to rotate. The rotation of the base 20 can drive the fixed phone cover 9 to rotate. Through the pressure plate 26, it drives the third telescopic rod 25 to rotate inside the second bearing 24. After the phone cover 9 rotates 90°, the second telescopic rod 15 controls the movement of the gantry slide 12 to polish the other side. In this way, the edges of all four sides can be automatically polished.
