Description

Technical Field

[0001] The invention relates to the field of graphite roasting, in particular to a continuous roasting device for isostatic graphite for semiconductors. Background Art

[0002] Semiconductor graphite materials are prepared by doping or modifying graphite. Doping refers to the introduction of some impurity atoms into the graphite lattice to change its electronic structure. Commonly used doping atoms are boron, phosphorus, nitrogen, etc. The doped graphite material has the characteristics of a semiconductor, that is, it can both conduct electricity and block current under certain conditions, which makes semiconductor graphite materials an ideal choice for manufacturing high-performance electronic devices.

[0003] Semiconductor graphite materials need to be roasted during production, specifically, graphite products are heat treated in a high temperature environment to remove impurities, optimize the crystal structure and improve the physical and chemical properties of the material. During the roasting process, impurities in the graphite blank are effectively removed. The existing Chinese public patent document: CN116296094A discloses a roasting device and a roasting method for graphite electrode production. By setting a roasting mechanism and using a feeding mechanism, multiple graphite electrode columns can be automatically indexed in sequence, and the graphite electrode columns can be automatically roasted in sequence. During the roasting process, there is no need to add fillers to the outside of the graphite electrode column to prevent the surface of the graphite electrode column from being covered with more fillers during subsequent roasting. Although continuous feeding of the graphite electrode column can be achieved, multiple heat pipes are in a sealed state, and it is difficult to replenish the graphite blank in the heat pipe. The graphite electrode column can only be repaired and reprocessed after the roasting is completed. Summary of the invention

The top of the mounting plate 10 is a cross-shaped structure, which is convenient for the sliding installation of the U-shaped plate 15.

[0034] When the mounting plate 10 moves, it can move along between the two guide frames 18, thereby improving the stability of the movement of the mounting plate 10, and the mounting plate 10 drives the U-shaped plate 15 to move synchronously. When the clamping plate 20 on the U-shaped plate 15 contacts the abutting plate 19 on the guide frame 18, the arc surface of the abutting plate 19 can contact the arc surface on the clamping plate 20, and the abutting plate 19 pushes the clamping plate 20 to move, so that the clamping plate 20 pushes the U-shaped plate 15 to move synchronously.

[0035] Working principle: First, the staff opens the feed valve 2, and puts the graphite blank into the roasting cylinder 4 located at the bottom of the feed valve 2, and enters between the two roasting covers 13. Then, the staff turns on the driving member 7, and the driving member 7 drives the two rotating rods 6 to rotate synchronously. The two rotating rods 6 drive the two toothed belts 8 to rotate synchronously through the two gears 9. The two toothed belts 8 drive the support rods 11 to move synchronously, so that the support rods 11 drive the mounting plate 10 to move between the two guide frames 18, and drive the four pulleys 12 to move along the outer side of the positioning block 3. At the same time, the mounting plate 10 drives the roasting The baking tube 4 moves along the inner side of the device shell 1, so that the baking tube 4 with the graphite blank is aligned with the first combustion nozzle 5. At this time, the combustion nozzle 5 processes the graphite blank between the two baking covers 13. At the same time, the toothed belt 8 drives another baking tube 4 to move to the bottom of the feed valve 2. Then, the staff loads the next graphite blank between the two baking covers 13 under the feed valve 2. Subsequently, the toothed belt 8 drives the baking tube 4 to move again, so that the baking tube 4 under the first combustion nozzle 5 is aligned with the bottom of the feed valve 14. At this time, the staff injects the filling material into the baking tube 4. The graphite blank is replenished in the baking tube 4, and then the toothed belt 8 moves the baking tube 4 after replenishment to the right below the second combustion nozzle 5, so that the combustion nozzle 5 processes the graphite blank again, and another baking tube 4 with graphite blank can be moved to the below of the first combustion nozzle 5, thereby realizing continuous baking and replenishment of the graphite blank. Finally, the graphite blank in the baking tube 4 is processed into a graphite product, and when the opening of the baking tube 4 is facing downward, the clamping plate 20 on the mounting plate 10 contacts the abutment plate 19 above the discharge port of the device housing 1, and the arc of the abutment plate 19 The U-shaped plate 15 is driven by the bracket 17 to move along the inner side of the roasting tube 4, and the roasting cover 13 drives the slider 30 to move along the outer side of the positioning rod 31, so that the two roasting covers 13 are separated from the graphite products stably, and the graphite products can be discharged downward through the discharge port, thereby achieving the effect of continuous roasting and automatic unloading, and facilitating timely feeding of graphite blanks, thereby improving the convenience of graphite blank processing.

[0037] In this embodiment: when the finished graphite product moves downward, it can contact the arc-shaped concave surface of the guide roller 24 on the U-shaped frame 22, so that the finished graphite product drives the guide roller 24 to rotate through the arc-shaped ribs 28 on the guide roller 24, so that the finished graphite product is supported in a vertical state and contacts with the guide roller 24 at the bottom of the U-shaped frame 22. Since the distance between the two guide rollers 24 at the bottom of the U-shaped frame 22 is smaller than the distance between the two guide rollers 24 at the top, the finished graphite product can push the two guide rollers 24 at the bottom away from each other, and drive the sleeve block 26 to move along the sliding cavity on the U-shaped frame 22 through the mounting rod 23, and use the elasticity of the spring 27 to press the guide roller 24 to position the finished graphite product, so that the staff can take the finished graphite product from the material trough between the two U-shaped frames 22, thereby achieving the effect of facilitating material taking.

Two symmetrically distributed moving blocks 34 are fixedly mounted on the outer side of the U-shaped frame 22.

One end of the adjusting handle 36 is fixedly connected to one end of the adjacent different-direction screw 33 to facilitate the rotation adjustment of the different-direction screw 33.

[0039] In this embodiment: when the size of the graphite product is large, the staff can rotate the adjustment handle 36 so that the adjustment handle 36 drives the corresponding counter-rotating screw 33 to rotate, and the counter-rotating screw 33 drives another counter-rotating screw 33 to rotate synchronously through the synchronous belt 35. The two counter-rotating screws 33 drive the two U-shaped frames 22 to move away from each other along the outer side of the mounting frame 21 through the moving block 34, so that the distance between the two guide rollers 24 can be adjusted according to the size of the graphite product, which is suitable for taking graphite products of various sizes.
