At the top end of the oven main body, there is an assembly seat. Inside one side of the assembly seat, there is a vacuum pump, and inside the other side of the assembly seat, there is a dry nitrogen gas box. The inner wall surface of the oven main body is provided with a heat preservation layer. On both sides of the inner wall of the heat preservation layer, two groups of moving seats are relatively arranged. The moving seats are long strips with an L-shaped cross-section. On the two sides of the two groups of moving seats close to each other, there are two groups of assembly grooves. Between the lower surfaces of the two groups of assembly grooves, there is a corrugated plate. Through holes are arranged through the inside of the corrugated plate. By setting the corrugated plate and the through holes, the bottom plane of the lithium battery does not fit the shape of the corrugated arc surface, realizing point-line support, reducing the contact area, increasing the evaporation area during the baking process of the lithium battery, and the through holes improve the circulation effect of water vapor, improving the baking efficiency and balance of the full-automatic lithium battery baking oven. However, for the operation of taking and placing lithium batteries into and out of the baking oven, all operations are carried out inside the baking oven, which is not convenient to use, affects the baking efficiency of lithium batteries, and the staff is easily scalded by high temperature, posing a safety hazard.

[0022] Please refer to Figures 1 to 4, in this practical embodiment, a fully automatic lithium battery baking oven includes a vacuum oven body 1, which is a vacuum baking oven for baking lithium batteries. The vacuum baking oven includes a vacuum chamber. There is a machine housing on the top of the vacuum chamber. In the machine housing, there is a vacuum pump for the vacuum chamber and a dry nitrogen tank. There is also a heater in the machine housing. Inside the vacuum chamber, there is a heating pipe electrically connected to the heater to achieve vacuum baking processing of lithium batteries. It also includes a control panel. All the electrical devices of this device are electrically connected to the control panel. The lithium battery vacuum oven body is a common technical device in this field, so no further explanation will be given here. A sealing frame 2 is fixedly connected to the front opening of the vacuum oven body 1. There is a lifting and adjusting mechanism on the outer side wall of the sealing frame 2. Both ends of the lifting and adjusting mechanism penetrate into the sealing frame 2 and are fixedly connected to a door 3. There is a sliding support mechanism on the inner bottom wall of the vacuum oven body 1. The upper end of the sliding support mechanism is fixedly connected to a moving platform 4. A lithium battery storage rack 5 is placed on the moving platform 4, which is prior art. On both sides of the rear end of the moving platform 4, there are two symmetrically arranged push rods 6 hinged. The upper ends of both push rods 6 are hinged to the inner side wall of the door 3.

[0023] The lifting and adjusting mechanism includes a concave housing 7 communicated with the outer side wall of the sealing frame 2. There is a driving mechanism at the lower part of one side of the concave housing 7. One end of the driving mechanism is fixedly connected to a rotating rod 8. The rotating rod 8 penetrates into the concave housing 7 and is fixedly connected to a first bevel gear 9 at both ends respectively. Both vertical inner walls of the concave housing 7 are rotatably connected to a lead screw 10 through bearing seats. The lower ends of both lead screws 10 are fixedly connected to a second bevel gear 11 meshed with the first bevel gear 9. There is a threaded block 12 threadedly connected to both lead screws 10. On the opposite sides of both threaded blocks 12, there is an adapter block 13 fixedly connected. The two adapter blocks 13 are respectively fixedly connected to both sides of the door 3. When the driving mechanism works, it drives the rotating rod 8 to rotate. Since the two first bevel gears 9 are respectively meshed with the two second bevel gears 11, it drives the two lead screws 10 to rotate simultaneously. Since the two lead screws 10 are respectively threadedly connected to the two threaded blocks 12, at this time, the two threaded blocks 12 move synchronously, which can drive the door 3 fixed to the two adapter blocks 13 to move upward to achieve the door opening action. At the same time, when the door 3 moves upward, it can drive the two push rods 6 to swing, and then drive the lithium battery storage rack 5 on the moving platform 4 to automatically move out of the vacuum oven body 1, so as to take and place the lithium battery from outside the vacuum oven body 1. The operation is more convenient, the work efficiency is improved, the degree of automation is high, and high-temperature scalding is avoided, improving the operation safety. On the contrary, when the door 3 moves downward for the door closing operation, it pushes the push rods 6 to swing, and then pushes the lithium battery storage rack 5 on the moving platform 4 to retract into the vacuum oven body 1 for baking processing, with a high degree of automation.

[0024] As Figure 4As shown in the figure: The driving mechanism includes a machine housing 14 fixed to the lower part of one side of the concave housing 7. One side of the machine housing 14 is fixedly connected with a stepping motor 15. The main shaft end of the stepping motor 15 penetrates into the machine housing 14 and is fixedly connected with a first gear 16. One end of the rotating rod 8 is fixedly connected with a second gear 17 meshed with the first gear 16. Starting the stepping motor 15 to work drives the first gear 16 to rotate. Since the first gear 16 is meshed with the second gear 17, the rotating rod 8 is driven to rotate, and the driving work is stable.

[0025] As Figure 4 shown in the figure: The diameter length of the first gear 16 is smaller than that of the second gear 17, which is more labor-saving and has a higher transmission efficiency.

[0026] As Figure 2 shown in the figure: The sliding support mechanism includes two symmetrically arranged chutes 18 opened on the inner bottom wall of the vacuum oven body 1. Slide bars 19 are slidably connected in both of the two chutes 18. The upper sides of the two slide bars 19 are fixedly connected with the moving table 4. When the moving table 4 is displaced, the slide bars 19 are driven to slide in the chutes 18, making the displacement of the moving table 4 more stable.

[0027] As Figure 2 shown in the figure: Positioning grooves 20 corresponding to the four legs of the lithium battery storage rack 5 are respectively opened at the four corners of the upper side wall of the moving table 4, which is convenient for positioning the lithium battery storage rack 5 and preventing deviation and shaking.

[0028] As Figure 1 shown in the figure: A glass window 21 is provided on the side wall of the box door 3 for observing the inside of the vacuum oven body 1. A sealing plate 22 is fixedly connected to the upper end of the box door 3 to ensure the sealing performance for vacuum baking.

[0029] As Figure 1 shown in the figure: Locking wheels 23 are fixedly connected to the four corners of the bottom of the vacuum oven body 1, which is convenient for the displacement or fixation of the device.

[0030] Working principle: When using this device to bake and process lithium batteries, start the stepper motor 15 to work, drive the first gear 16 to rotate. Since the first gear 16 meshes with the second gear 17, the rotating rod 8 is driven to rotate, ensuring stable operation. Since the two first bevel gears 9 respectively mesh with the two second bevel gears 11, the two lead screws 10 are driven to rotate simultaneously. Since the two lead screws 10 are respectively threadedly connected to the two threaded blocks 12, at this time, the two threaded blocks 12 are displaced synchronously, which can drive the door 3 fixed to the two connecting blocks 13 to move upward, realizing the door opening action. At the same time, when the door 3 moves upward, the two push rods 6 can be driven to swing, and then drive the lithium battery storage rack 5 on the moving platform 4 to automatically move out of the vacuum oven body 1, so as to take and place the lithium battery from the outside of the vacuum oven body 1. The operation is more convenient, the work efficiency is improved, the automation degree is high, and high-temperature scalding is avoided, improving the operation safety. On the contrary, when the door 3 moves downward for the closing operation, the push rod 6 is pushed to swing, and then the lithium battery storage rack 5 on the moving platform 4 is pushed to retract into the vacuum oven body 1 for baking and processing, with a high degree of automation.
