Description

Technical Field

[0001] The present invention relates to the technical field of graphite part surface coating formation equipment, and specifically to a surface composite coating equipment and method for graphite parts. Background Art

[0002] Graphite is an important non-metallic material with extremely high thermal conductivity and electrical conductivity, so it is widely used in the electronics industry and optoelectronics industry. However, due to the easy corrosion and wear of the graphite surface, it is easily damaged during use; to solve this problem, the graphite surface coating technology has emerged. The graphite surface coating technology refers to coating a special material on the graphite surface to enhance the surface hardness and corrosion resistance of the graphite;

[0003] According to a method for depositing a silicon carbide coating on the surface of a graphite part by using a solution method disclosed in the existing Chinese patent CN114292129B, the graphite part is ultrasonically cleaned and surface treated with oxygen plasma; Si and Cr are loaded into the crucible, and Cr is used as a metal auxiliary solution. The graphite part is fixed to the lifting rod and placed in a vacuum chamber. High-purity argon gas is filled into the furnace chamber and the heating system is turned on for heating. When the predetermined temperature is reached, the metal auxiliary solution is melted; the graphite part is lowered below the liquid level, and the graphite part moves at a rotation speed of 15-30 r / s and a lifting speed of 40-120 μm / h, and the crucible rotates in the opposite direction; during this process, the coating deposition of the graphite part is realized; after the deposition is completed, the graphite part is pulled out of the liquid level, and the growth process ends after slow cooling. The coating obtained by this method has higher density, higher purity, higher uniformity, stronger adhesion to graphite, the coating thickness can be between 1 μm and 500 μm, and the cost is lower;

[0004] The method provided by this patent for depositing a silicon carbide coating on the surface of a graphite part by using a solution method realizes the effect of forming a silicon carbide coating on the outer side of the graphite part by sinking the graphite part into the metal auxiliary solution in the kettle body and setting a specific environment. However, the equipment provided by this method cannot realize pipeline operation during use, the operation efficiency is low, it is not suitable for large-scale silicon carbide coating deposition work of graphite parts, and it needs to clean the graphite part by plasma outside the kettle body before working, and then load the graphite part into the kettle body after cleaning. However, the graphite part is easily contaminated again during the transfer process, thereby reducing the coating quality.

[0005] Therefore, it is necessary to provide a surface composite coating equipment and method for graphite parts to solve the above technical problems. Summary of the Invention

Detailed implementation manners

[0044] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0045] Please refer to the figures to the figures, and the present invention provides the following technical solutions:

[0046] Embodiment 1. This embodiment provides a surface composite coating device for graphite parts, including a conveying frame 1. A chain transmission assembly 2 is installed on the conveying frame 1. A number of load-bearing members 3 for carrying graphite parts are equidistantly installed on the chain transmission assembly 2. The chain transmission assembly 2 conveys the graphite parts by circularly conveying the load-bearing members 3. The lower kettle body 4 is fixed to the inner side of the upper end of the conveying frame 1, and the top surface height of the lower kettle body 4 is lower than the bottom surface height of the load-bearing member 3 at the upper end. The lower kettle body 4 is loaded with a metal auxiliary solution. The upper kettle body 5 is slidably arranged on the conveying frame 1 and is directly opposite to the lower kettle body 4. The upper kettle body 5 can slide down to press a load-bearing member 3 opposite to it against the lower kettle body 4, and form a sealed chamber with the load-bearing member 3 and the lower kettle body 4. A pushing assembly 6 is fixed to the inner wall of the upper kettle body 5, which can push the graphite part into the metal auxiliary solution in the lower kettle body 4 after the upper kettle body 5 presses a load-bearing member 3 to form a sealed chamber with the lower kettle body 4. An elevating mechanism 7 for driving the upper kettle body 5 to lift and lower is also fixed on the conveying frame 1. The upper kettle body 5 includes a vacuum pumping device installed on it and communicating with its inner cavity, a heating device fixed to its inner side, and a gas filling device communicating with its inner cavity. The vacuum pumping device is used to pump the air in the sealed chamber when the upper kettle body 5 presses the load-bearing member 3 against the lower kettle body 4 to form a sealed chamber. The heating device is used to increase the temperature inside the sealed chamber, and the gas filling device is used to fill high-purity argon gas into the sealed chamber. The heating device, the vacuum pumping device, and the gas filling device are all prior arts and are not shown in the figure, and their structures and working principles will not be elaborated here;

[0047] The upper kettle body 5 further includes a top frame 51 fixed to its top. Four corners of the bottom of the top frame 51 are respectively fixed with lifting slide rods 52. A first sliding sleeve 53 is slidably sleeved on the outer wall of the lower end of the lifting slide rod 52, and the first sliding sleeve 53 is fixed to the outer wall of the conveying frame 1. The elevating mechanism 7 includes first electric push rods 71 symmetrically fixed on the conveying frame 1. The extending end of the first electric push rod 71 is fixed to the bottom surface of the top frame 51. The upper kettle body 5 is slidably connected to the conveying frame 1 through the first sliding sleeve 53 and the lifting slide rods 52. By driving the first electric push rod 71 to contract or extend, the upper kettle body 5 can be driven to descend and ascend;

[0048] Two groups of synchronous cleaning assemblies 8 are provided. The two groups of synchronous cleaning assemblies 8 are symmetrically fixed on the top surface of the conveying frame 1 and are used to perform synchronous cleaning work on the graphite parts when conveying the graphite parts between the upper kettle body 5 and the lower kettle body 4;

[0049] When in use, a mechanical arm is provided at both the loading and unloading ends of the whole equipment, and the loading and unloading of graphite parts are performed by the mechanical arm. After the graphite parts are placed inside the carrier 3, they are transported to the upper kettle body 5 under the conveyance of the chain conveyor assembly 2 until they reach the synchronous cleaning assembly 8, and the cleaning work is performed while being transported. The conveying is stopped until the carrier 3 is facing the upper kettle body 5 and the lower kettle body 4, and then the upper kettle body 5 is driven down by the lifting mechanism 7 to press the carrier 3, and the carrier 3 is pressed against the top of the lower kettle body 4, so that the upper kettle body 5, the carrier 3 and the lower kettle body 4 form a sealed inner cavity, and the graphite parts are covered inside, and then vacuumized, heated and passed. High-purity argon gas then drives the push assembly 6 to move the graphite parts to the metal auxiliary solution in the lower kettle body 4 to generate the coating. After the generation is completed, the graphite parts are raised and reset, and then left to stand to drain the residual metal auxiliary solution and slowly cooled. Then the vacuum state in the inner cavity is released, and the upper kettle body 5 is raised to reset, and then the carrier 3 is continuously transported. At the unloading end, the mechanical arm unloads the graphite parts after the coating is generated into the cleaning equipment to clean the residual metal auxiliary solution, and the subsequent coating generation work of the graphite parts is continuously repeated, so that the coating generation work of the graphite parts can be realized in an assembly line manner, which greatly improves the production efficiency.

[0050] The chain conveying assembly 2 includes a rotating rod 201 symmetrically connected to the two ends of the conveying frame 1 through bearings, and sprockets 202 are symmetrically fixed at the two ends of the rotating rod 201. A chain 203 is connected between two corresponding sprockets 202 along the length direction of the conveying frame 1. When conveying graphite parts, the rotating rod 201 is driven to rotate by a rotating device such as a motor, which drives the sprocket 202 to rotate, so that the chain 203 is conveyed. The two chains 203 are conveyed in the same direction at the same time, so that the carrier 3 moves, thereby realizing the conveying of the graphite parts;

[0051] The bearing member 3 includes a bearing frame 301 arranged between the two chains 203, a connecting rod 302 is symmetrically fixed on the outer wall of the bearing frame 301 close to the chain 203, the end of the connecting rod 302 is connected to the chain 203, and a clamping frame 303 is slidably connected to the inner wall of the bearing frame 301, a first spring 304 is symmetrically fixed on the outer periphery of the upper end of the clamping frame 303, the bottom of the first spring 304 is fixed to the top surface of the bearing frame 301, a magnet ring 305 is also fixed on the inner wall of the upper end of the clamping frame 303, a bearing seat 306 is adsorbed on the bottom of the magnet ring 305, and the bearing seat 306 is nested in the clamping frame 303, a plurality of openings 307 are formed at equal intervals at the bottom of the bearing seat 306, and sealing gaskets 9 are fixed to the top and bottom surfaces of the clamping frame 303;

[0052] After the carrier 3 carrying the graphite piece is transported to a position directly opposite the upper kettle body 5 and the lower kettle body 4 and stops, the upper kettle body 5 is driven down by the lifting mechanism 7. After the bottom of the upper kettle body 5 contacts the sealing gasket 9 on the top surface of the pressing frame 303, the upper kettle body 5 pushes the pressing frame 303 to slide downward, and the pressing frame 303 slides to compress the first spring 304. Subsequently, the bottom of the pressing frame 303 contacts the top surface of the lower kettle body 4. Continuing to drive the upper kettle body 5 downward causes the upper kettle body 5 to press the pressing frame 303, and the pressing frame 303 is pressed against the top surface of the lower kettle body 4. The two sealing gaskets 9 improve the airtightness of the connection between the upper kettle body 5 and the pressing frame 303 and between the lower kettle body 4 and the pressing frame 303. The upper kettle body 5 and the pressing frame 303 and the lower kettle body 4 form a closed inner cavity to cover the graphite piece, and then the coating generation work can be carried out. During the rising process of the upper kettle body 5 after the generation is completed, the bottom of the pressing frame 303 is separated from the lower kettle body 4. As the upper kettle body 5 rises, the upper kettle body 5 is also separated from the pressing frame 303. Driven by the resilience of the first spring 304, the pressing frame 303 slides upward in the carrying frame 301 to reset;

[0053] The pushing assembly 6 includes a second electric push rod 61 fixed on the top inner wall of the upper kettle body 5, and four magnet push rods 62 are symmetrically fixed on the extending end of the second electric push rod 61;

[0054] When a carrier 3 faces the upper kettle body 5, the magnet ejector rod 62 faces the connecting ring 3061 fixed on the inner wall of the top surface of the carrier seat 306. After the upper kettle body 5 pushes the pressing frame 303 to press tightly against the lower kettle body 4, the pushing assembly 6 works. The second electric push rod 61 extends, causing the four magnet ejector rods 62 to move downward. The magnet ejector rods 62 move and insert into the connecting ring 3061. Both the connecting ring 3061 and the carrier seat 306 are made of iron. Therefore, when the pushing assembly 6 is not working, the carrier seat 306 is adsorbed on the magnet ring 305 by the adsorption of the magnet ring 305. It should be emphasized that after placing the upper graphite piece, the adsorption force of the magnet ring 305 on the carrier seat 306 can fully support the carrier seat 306 and the graphite piece, ensuring that the carrier seat 306 will not separate from the magnet ring 305 until the pushing assembly 6 works. The second electric push rod 61 extends, causing the magnet ejector rods 62 to insert into the connecting ring 3061 to adsorb the connecting ring 3061 and the carrier seat 306 until the bottom of the magnet ejector rod 62 contacts the carrier seat 306. Then, the second electric push rod 61 continues to extend, which can push the carrier seat 306 to separate from the magnet ring 305 and then move downward until the carrier seat 306 completely separates from the pressing frame 303. After that, the carrier seat 306 is adsorbed on the magnet ejector rod 62 by the adsorption of the magnet ejector rod 62. Then, the second electric push rod 61 continues to extend, causing the carrier seat 306 to descend and immerse the graphite piece into the metal auxiliary solution. After the reaction ends, the second electric push rod 61 contracts. The carrier seat 306 inserts into the pressing frame 303 and adsorbs to the magnet ring 305, and then the second electric push rod 61 continues to contract. The magnet ejector rod 62 continuously rises and separates from the carrier seat 306 until it resets. Then, the lifting mechanism 7 drives the upper kettle body 5 to rise, ending the coating generation work;

[0055] The synchronous cleaning assembly 8 includes a horizontally arranged sliding rod 81 fixed on the top surface of the conveying frame 1. A horizontally arranged sliding sleeve 82 is sleeved on the outer wall of the horizontally arranged sliding rod 81. A second spring 83 is also sleeved on the outer side of one end of the horizontally arranged sliding rod 81. One end of the second spring 83 is fixed to the outer wall of the conveying frame 1, and the other end is fixed to the end of the horizontally arranged sliding sleeve 82. The horizontally arranged sliding sleeve 82 is fixed to the emitting end 12 of the plasma device 10. The plasma device 10 is installed below the conveying frame 1 and there are two of them. The plasma devices are connected to the emitting end 12 through pipelines 11. The specific connection method and working principle of the plasma device 10, the pipeline 11, and the emitting end 12 are all prior arts and will not be elaborated here;

[0056] A follower assembly 84 is also provided on the outer wall of the sending end 12. The follower assembly 84 is used to make the sending end 12 move synchronously with the graphite piece when the graphite piece is transported to the top of the lower kettle body 4. The follower assembly 84 includes a locking assembly 841 fixed on the outer wall of the sending end 12 so that the sending end 12 can be connected with the carrier 3 and move synchronously, and an unlocking assembly 842 fixed on the outer wall of the upper kettle body 5 for releasing the connection between the sending end 12 and the carrier 3 so that it is reset by the rebound force of the second spring 83; the locking assembly 841 includes a sliding hole connected to the outer wall of the sending end 12 on the side close to the graphite piece conveying direction. The driven rod 8411 on the upper part, when the upper kettle body 5 does not descend to drive the unlocking assembly 842 to unlock, the lower end of the driven rod 8411 faces the bearing frame 301, and a through hole 8412 is provided at the upper end of the driven rod 8411. A lifting and flipping bar 8413 is rotatably connected to the outer wall of the issuing end 12 close to the driven rod 8411 through an axle pin, and one end of the lifting and flipping bar 8413 is inserted into the inner side of the through hole 8412; the unlocking assembly 842 includes an unlocking push rod 8421 symmetrically fixed on the outer wall of the upper kettle body 5, and the unlocking push rod 8421 faces the end of the lifting and flipping bar 8413 away from the through hole 8412;

[0057] During the conveying process of the carrier 3, when the carrier frame 301 abuts against the lower end of the connecting rod 302, the issuing end 12 is facing the inner side of the carrier seat 306. As the chain conveying assembly 2 continues to convey the carrier frame 301 to the side of the lower material end, the issuing end 12 is pushed to move together with the carrier frame 301. During the movement, the plasma equipment 10 works so that the issuing end 12 cleans the graphite parts inside the carrier seat 306, so that the graphite parts are cleaned while being conveyed. The driven rod 8411 is pushed by the carrier frame 301 to drive the issuing end 12 to slide along the horizontal sliding rod 81 to the side of the lower material end and compress the second spring 83 until the carrier frame 301 reaches the position facing the upper kettle body 5. At this time, the unlocking push rod 8421 is facing the end of the lifting and flipping bar 8413 away from the through hole 8412, and then the upper kettle body 5 is driven to descend, and the unlocking push rod 8421 is synchronously descended, and the unlocking push rod 8421 first abuts against the lifting and flipping bar 8413 The outer wall is then pushed to flip the lifting and flipping bar 8413, thereby pushing the driven rod 8411 to slide upward, so that the driven rod 8411 is staggered with the supporting frame 301, and then the second spring 83 is reset to push the issuing end 12 to slide along the horizontal slide bar 81 to the upward material end. During the sliding process, the lifting and flipping bar 8413 and the unlocking push rod 8421 are staggered, and the driven rod 8411 will drop to the supporting frame 301 under the action of gravity, and then continue to slide with the supporting frame. After 301 is separated, the driven rod 8411 will completely drop and reset, and then the output end 12 will reset, and then the upper kettle body 5 will be pressed against the pressing frame 303, and the pressing frame 303 will be pressed against the lower kettle body 4, and then the coating generation work will be carried out, until the coating is produced, the graphite piece is removed from the upper kettle body 5, and the next graphite piece continues to enter between the upper kettle body 5 and the lower kettle body 4, and the next graphite piece continues to be cleaned, and the cleaning and coating generation work of the graphite piece is carried out repeatedly;

[0058] At the end of the graphite parts being transported into the upper kettle body 5 and the lower kettle body 4, the graphite parts are cleaned until the upper and lower kettle bodies 4 are closed. Compared with the traditional equipment that uses cleaning equipment to clean the graphite parts and then transports them into the kettle body, the present invention can perform cleaning work during the process of transporting the graphite parts into the inner side of the kettle body, thereby reducing the probability of the graphite parts being contaminated again.
