[0002] With the rapid development of electric vehicles and new renewable energy sources, lithium batteries, as a high-performance, high-energy-density energy technology, are gradually replacing traditional nickel-metal hydride and lead-acid batteries and becoming the mainstream. As a key component of lithium-ion batteries, lithium-ion anode materials are facing higher requirements for quality and production capacity. Graphitization is a key process step in the production of anode materials.

[0003] During the graphitization process, a cover is typically installed on the feed box inside the graphitization furnace to separate the material (product material) from other materials. Installing and removing the cover is a key process step. Because the temperature of the cover can reach several hundred degrees Celsius during the graphitization process, manually removing the cover poses a significant safety hazard and can easily damage the cover. Therefore, the material is typically left to cool naturally to a lower temperature before manual removal. However, prolonged storage can expose the material to oxygen in the air, leading to oxidation and compromising material quality. Utility Model Content

[0027] The cover placing device 1 and the cover opening device 3 are staggered in a first direction X and a second direction Y. The first direction X and the second direction Y are perpendicular to each other on the same top projection plane.

[0028] The cover-lifting device 3 has an A end and a B end opposite to each other in the second direction Y. The A end is provided with a first feed port 31 and a first discharge port 32 , and the B end is provided with a second discharge port 33 .

[0029] like Figure 1 、 Figure 2 、 Figure 3 As shown, the cover placing device 1 and the cover opening device 3 both include a support frame 34 , a platform 35 , a gripping mechanism 38 , and a first conveyor 36 and a second conveyor 37 provided on the platform 35 .

[0030] The platform 35 is mounted on the upper end of the support frame 34, forming a gantry with the support frame 34 and the platform 35. The production line 10 passes through the lower portion of the gantry. The platform 35 and the first conveyor 36 both extend in the second direction Y. The second conveyor 37 extends in the first direction X and connects to the first conveyor 36. The first feed port 31 and the second discharge port 33 are connected via the first conveyor 36.

[0031] The first conveyor 36 can be a chain conveyor, and the second conveyor 37 can be a roller conveyor that can be assembled. The first conveyor 36 and the second conveyor 37 are both driven by the motor 310 (such as Figure 4 The motor 310 can rotate forward and reverse to change the transport direction of the tray 7.

[0032] The platform 35 is also provided with a vacuum pump 39 and a dust collector 8. The air outlet of the dust collector 8 is arranged outward, which is convenient for the manipulator 381 to grab the cover plate and place it beside it for dust removal.

[0033] like Figure 3As shown, the gripping mechanism 38 includes a manipulator 381, a fixture 382, an identification device 383 and a bracket 384. The manipulator 381 is a six-axis robotic arm, a purchased part, and its upper end is fixed to the platform 35 through a mounting base. The end of the manipulator 381 is installed with a fixture 382. The fixture 382 is a vacuum suction cup, which is connected to the vacuum pump 39 and adsorbs the cover plate through negative pressure. The identification device 383 is a camera, which is mounted on the platform 35 through a bracket 384, and the identification device 383 is located above the manipulator 381. The identification device 383, the manipulator 381 and the control center of the entire processing system are electrically connected to identify the integrity of the cover plate and output instructions for the manipulator 381 to act. The working range of the manipulator 381 may involve the entire platform 35.

[0034] The elevator 4 is located at the A end, the B end, the C end and the D end. If there is only one uncovering device 3, the elevator 4 at the D end is eliminated. The elevator 4 drives the lifting platform on it to move up and down through a chain, and the chain is driven by a motor. The side walls of the elevator 4 facing the A end, the B end, the C end and the D end are each provided with an opening, and the openings form the first feed port 31, the second discharge port 33, the second feed port 11 and the third feed port 12 respectively. Alternatively, the lifting platform protrudes to the outside of the elevator 4, and the first feed port 31, the second discharge port 33, the second feed port 11 and the third feed port 12 are correspondingly arranged at the end of the first conveyor 36. A second conveyor line 9 is provided next to the elevator 4 at the A end, and the lifting platform on the elevator 4 at the A end connects the second conveyor line 9 to the first conveyor 36. The lifting platforms on the elevators 4 between the B end, the C end and the D end connect the first conveyor line 2 to the first conveyor 36. The second conveying line 9 is used to supply materials to the capping device 1 .

[0035] The first conveyor line 2 comprises two lines, one connecting the elevator 4 between the B and C ends of one cover-lifting device 3 and the other connecting the elevator 4 between the B and D ends of the other cover-lifting device 3. The first conveyor line 2 is formed by splicing together multiple roller conveyors, assembled according to the length of the cover-lifting device 3 and the cover-placement device 1. The first conveyor line 2 not only transports the cover sheets on the tray 7 from the second discharge port 33 to the second feed port 11, but also serves as a buffer for the cover sheets. The first conveyor line 2 can be divided into upper and lower sides or multiple layers for buffering the cover sheets.

[0036] like Figure 1 As shown, the first discharge port 32 is connected to the material box 5 located on the ground through an inclined slide 6. The first discharge port 32 is used to remove incomplete cover plates and store them in the material box 5.

[0037] The pallet 7 moves back and forth between the first conveyor line 2, the first conveyor 36, the second conveyor 37, and the lift platform of the elevator 4. A tool for securing the cover plate is provided on the pallet 7. A transplanter 311 is provided between the first conveyor 36 and the second conveyor 37, capable of shifting the pallet 7 between the first direction X and the second direction Y.

[0038] The present invention further provides a graphitization furnace processing system, comprising three production lines 10 arranged in a second direction Y (the number of production lines 10 corresponds to the number of cover placement devices 1 and cover removal devices 3). Each production line 10 is provided with at least one graphitization furnace extending in a first direction X. The cover placement and removal device is mounted above the production lines 10.

[0039] The processing method of the graphitization furnace processing system of the utility model comprises the following steps:

[0040] S1, after the graphitization furnace on the production line 10 corresponding to the lid-lifting device 3 is processed, the graphitization furnace moves along the track line on the production line 10 to the lower end of the lid-lifting device 3.

[0041] S2, start the manipulator 381 of the cover-opening device 3, suck the cover plate through the clamp 382 and lift it into the working range of the identification device 383.

[0042] S3: The recognition device 383 is activated to check the integrity of the cover's appearance. If the cover is found to be complete, the robot 382 moves the cover to the dust collector 8 for dust removal. After dust removal, the robot 381 places the cover on the tray 7 of the second conveyor 37 and activates the clamp on the tray 7 to secure the cover. The second conveyor 37 is then activated to move to the transplanter 311. The transplanter 311 then transfers the cover to the first conveyor 36, moving the tray 7 and the cover toward the second discharge port 33. If the cover is found to be incomplete, the robot 381 directly places the cover at the first discharge port 32, whereupon the cover falls into the hopper 5 via the carriage 6.

[0043] S4, start the elevator 4 at the B end, so that the lifting platform rises to the second discharge port 33, the lifting platform is flush with and connected to the first conveyor 36 on the lid-lifting device 3, and the tray 7 is moved horizontally from the first conveyor 36 to the lifting platform. The lifting platform is provided with a blocking cylinder and a clamping cylinder to limit the position of the tray 7.

[0044] S5. Start the lift 4 at end B to lower the platform to the level of the first conveyor line 2. Release the blocking cylinder and clamping cylinder on the platform to move the tray 7 and cover plate on the platform to the first conveyor line 2. To ensure the connection between the actions of steps S4 and S5, a roller line with the same moving direction as the first conveyor 36 can be installed on the platform, and a push cylinder can be installed on the inner side of the platform to push the tray 7 onto the first conveyor line 2.

[0045] In step S6, the tray 7 drives the cover plate along the first conveyor line 2 from end B to end C (end D). The elevator 4 at end C (end D) is activated, raising the platform on the elevator 4 to the second feed port 11 (third feed port 12). The platform is aligned with and connected to the first conveyor 36 on the cover placement device 1. The tray moves from the platform to the first conveyor 36 and then, via the transplanter 311, onto the second conveyor 37.

[0046] S7, start the robot 381 on the cover placing device 1, grab the cover on the second conveyor 37, and place it on the graphitization furnace of the production line 10 of the cover placing device 1; complete one cover placing action.

[0047] S8: Because some incomplete caps are rejected, restocking is required. The second conveyor line 9 is activated, and new caps are transported from the second conveyor line 9 through the elevator 4 at end A, the first conveyor 36, the elevator 4 at end B, the first conveyor line 2, and the elevator 4 at end C or D, and then enter the first conveyor 36 of the cap placement device 1. The robot 381 of the cap placement device 1 then places the caps on the graphitization furnace of the production line 10 of the cap placement device 1, completing the restocking operation.

[0048] Repeat the above steps until all the cover plates on the cover-lifting device 3 are removed and the material is taken out.

[0049] The cover plate opening and releasing device provided by the utility model can realize automatic opening and releasing of the cover plate, thereby avoiding the risk of manual opening of the cover plate in a high temperature environment and the influence of long-term parking on material quality.
