[0002] In the manufacturing process of the temperature equalizer, the diffusion welding method is often used. Diffusion welding is a kind of pressure welding. It refers to the process in which the surfaces in contact with each other are brought close to each other under the action of high temperature and pressure, and local plastic deformation occurs. After a certain period of time, the atoms in the bonding layer diffuse with each other, forming a new diffusion layer at the interface, thereby forming an overall reliable connection.

[0003] At present, graphite jigs are used for diffusion welding of temperature balancing plates. Graphite jigs are mostly used to manufacture a graphite disk that is compatible with the inner diameter of the diffusion welding furnace. During processing, the staff needs to place the temperature balancing plates. However, if one temperature balancing plate is not placed correctly, the welding process cannot be carried out intact, resulting in all the temperature balancing plates on the entire graphite disk being scrapped. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides a graphite jig for preparing ultra-thin temperature equalizing plates for mobile phones, which solves the problem that if the temperature equalizing plates are not placed correctly, they cannot be processed intact, thus causing all the temperature equalizing plates on the entire graphite disk to be scrapped.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a graphite jig for preparing an ultra-thin temperature equalizing plate for a mobile phone, comprising a fixing seat, a hollow plate is connected to the inner wall of one side of the fixing seat, a slide groove is provided on the fixing seat, a guide rod is connected to the fixing seat, the fixing seat is overlapped with the fixing plate through the guide rod, a connecting block is rotatably connected to one side of the fixing seat, a threaded rod is connected to the connecting block, a moving block is installed on the threaded rod, and a threaded sleeve is installed on the moving block;

[0023] A slide groove 3 is provided on the fixed seat 1, a guide rod 4 is connected to the fixed seat 1, a fixing plate 5 is overlapped on the fixed seat 1 through the guide rod 4, a connecting block 6 is rotatably connected to one side of the fixed seat 1, a hexagonal groove is provided on the side of the connecting block 6 away from the threaded rod 7, a friction ring 21 is sleeved on the connecting block 6, and anti-skid patterns are provided on the friction ring 21. The friction between the connecting block 6 and the inner wall of the fixed seat 1 is increased by the anti-skid patterns on the friction ring 21, so as to avoid accidental rotation of the connecting block 6 and reduce the fixing effect.

[0024] A threaded rod 7 is connected to the connecting block 6, a moving block 8 is installed on the threaded rod 7, a threaded sleeve 9 is installed on the moving block 8, the threaded rod 7 is rotatably connected in the slide groove 3, the moving block 8 slides in the slide groove 3, the threaded sleeve 9 is threadedly matched with the threaded rod 7, when the threaded rod 7 is rotated by the connecting block 6, the moving block 8 will move along the threaded rod 7 through the threaded match between the threaded sleeve 9 and the threaded rod 7, thereby driving the pressure plate 10 to press and fix the multiple fixed plates 5.

[0025] The moving block 8 is connected to a pressure plate 10, a second slot 22 is provided on the pressure plate 10, a sliding hole 23 is opened on the pressure plate 10, and the pressure plate 10 slides on the guide rod 4 through the sliding hole 23. When the moving block 8 drives the pressure plate 10 to move, the guide rod 4 will guide the movement of the pressure plate 10, so that the pressure plate 10 can move smoothly.

[0026] Grooves 11 are provided on both sides of the fixing plate 5, notch grooves 12 are provided on the fixing plate 5, hook grooves 13 are provided on both sides of the fixing plate 5, an insert plate 14 is connected to the fixing plate 5, a first slot 15 is provided on the fixing plate 5, first springs 16 are connected to the inside of the first slot 15 on both sides, a clamping block 17 is connected to one end of the first spring 16, the insert plate 14 is engaged with the first slot 15 and the second slot 22, clamping grooves 18 are provided on both sides of the insert plate 14, the clamping block 17 slides in the fixing plate 5 and is engaged with the clamping groove 18, and the insertion plate 14 is engaged with the first slot 15, so that the staff can quickly position the fixing plate 5 to reduce the misalignment and deflection of the temperature equalizing plate.

[0027] The working principle of the utility model is:

[0028] The staff inserts the plug board 14 into the first slot 15 so that the temperature equalizing plate can be located between the two fixed plates 5. As the plug board 14 is inserted, the plug board 14 pushes the block 17 into the fixed plate 5 to compress the first spring 16. After the plug board 14 is fully inserted into the first slot 15, the first spring 16 rebounds and pushes the block 17 into the slot 18, so that the block 17 and the slot 18 are interlocked, thereby fixing the two fixed plates 5 together. Then, the multiple fixed plates 5 are placed in the two guides through the hook slot 13. On the rod 4, the staff rotates the connecting block 6 with an Allen wrench, so that the connecting block 6 can drive the threaded rod 7 to rotate. At this time, the moving block 8 will drive the pressure plate 10 to move along the threaded rod 7 through the threaded sleeve 9, so that the pressure plate 10 pushes the multiple fixed plates 5, and the fixed plates 5 push and squeeze the movable plate 20, so that the movable plate 20 compresses the second spring 19, thereby pushing the movable plate 20 through the rebound of the second spring 19, so that the movable plate 20 cooperates with the pressure plate 10 to clamp and fix the multiple fixed plates 5, and finally sends them into the diffusion welding furnace for diffusion welding.
