A fixing hole 14 and a limiting groove 13 are respectively provided on one side of the connecting seats 3 and one side of the support frames 4. A limiting tube 15 is fixedly installed on one side of the connecting seats 3. A limiting post 16 is movably connected to the inner circular wall of the limiting tube 15. A second spring 17 is movably connected to the outer circular wall of the limiting post 16. The limiting post 16 is movably connected to the fixing hole 14 and the limiting groove 13. Finally, a clamping assembly is used to clamp and position mobile phone back panels 2 of different sizes.

[0026] When in use, if the support frame 4 needs to be replaced to adapt to different sizes of mobile phone back panels 2, manually pull the limiting post 16 to disengage it from the limiting groove 13. The magnet 18 will no longer be attracted to the bottom of the support frame 4. Pull the support frame 4 upward to disengage it from the connecting seat 3 to complete modular disassembly, which is convenient for maintenance and adaptation to different sizes of mobile phone back panels 2.

[0027] In this embodiment, the clamping assembly includes: a positioning chamber 5, which is disposed on one side of the support frame 4. The support frame 4 and the positioning chamber 5 are connected by a hinge. Two support holes 6 are opened on one side of the positioning chamber 5. A pull rod frame 8 is movably sleeved inside the support holes 6. Two limiting plates 7 are fixedly installed on one side of the interior of the positioning chamber 5. The limiting plates 7 are movably sleeved with the pull rod frame 8. Two movable clamping plates 10 and two first springs 9 are fixedly sleeved on the exterior of the pull rod frame 8. The first springs 9 are fixedly installed on one side of the limiting plates 7. Two fixed clamping plates 12 are fixedly installed on one side of the interior of the positioning chamber 5.

[0028] In use, when clamping and fixing, manually move the fixing post 22 to drive the rotating connecting frame 20 to rotate, so that it is separated from the outside of the support frame 4. Then, rotate the positioning chamber 5 to a horizontal state through the hinge, pull the pull rod frame 8 to drive the two moving clamps 10 to move under the support of the limiting plate 7, and compress the first spring 9, placing the ceramic mobile phone back plate 2 between the fixed clamp 12 and the moving clamp 10. Slowly release the pull rod frame 8, and the first spring 9 pushes the moving clamp 10 to cooperate with the fixed clamp 12 to clamp the ceramic mobile phone back plate 2.

[0029] In this embodiment, elastic plates 11 are fixedly installed on one side of the fixed clamping plate 12 and the movable clamping plate 10 respectively. A support base 21 is fixedly installed on the top surface of the positioning chamber 5. A rotating connecting frame 20 is movably sleeved inside the support base 21. The rotating connecting frame 20 is movably sleeved with the support frame 4. A fixed column 22 is fixedly installed on one side of the rotating connecting frame 20. Several mounting holes 19 are opened on the top surface of the base 1. A rectangular groove is opened on the bottom surface of the connecting seat 3. A magnet 18 is fixedly sleeved inside the rectangular groove.

[0030] In use, the elastic sheet 11 can be bent to fit the shape of the ceramic phone back panel 2 to ensure the clamping effect. After clamping, the positioning chamber 5 is rotated back to its original position, and the rotating connecting frame 20 is rotated to hook onto the support frame 4 to keep the phone back panel 2 in a vertical position.

[0031] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0032] When the user needs to vertically sinter and position the mobile phone back panel 2 using the base 1, the base 1 is fixed to the conveyor platform through the mounting hole 19. The conveyor platform then sends the phone into the sintering furnace for baking and sintering. During clamping, the fixing column 22 is manually moved to rotate the rotating connecting frame 20, causing it to detach from the outside of the support frame 4. Then, the positioning chamber 5 is rotated to a horizontal position via the hinge. The pull rod 8 is pulled to move the two movable clamping plates 10 under the support of the limiting plate 7, compressing the first spring 9. The ceramic mobile phone back panel 2 is placed between the fixed clamping plate 12 and the movable clamping plate 10. The pull rod 8 is slowly released, and the first spring 9 pushes the movable clamping plate 10 to cooperate with the fixed clamping plate 12 to clamp the ceramic mobile phone back panel 2. The elastic sheet 11 can be bent to fit the shape of the ceramic phone back panel 2, ensuring the clamping effect. After clamping, the positioning chamber 5 is rotated back to its original position, and the rotating connecting frame 20 is rotated to hook onto the support frame 4, keeping the phone back panel 2 in a vertical position for conveying and sintering. When the support frame 4 needs to be replaced to accommodate different sizes of phone back panels 2, the limiting post 16 is manually pulled to disengage it from the limiting groove 13. The magnet 18 no longer adheres to the bottom of the support frame 4, and the support frame 4 is pulled upward to disengage it from the connecting seat 3, completing the modular disassembly. This facilitates maintenance and adaptation to different sizes of ceramic phone back panels 2, and allows for clamping, fixing, and vertical setting of several phone back panels 2 at once, improving operational efficiency and making it quite practical.
