Description

Technical Field

[0001] The utility model relates to the technical field of sintering devices, in particular to a sintering device for battery positive electrode materials. Background Art

[0002] Battery positive electrode material refers to the positive electrode active substance used to manufacture lithium-ion batteries, nickel-hydrogen batteries, etc., usually including some metal oxides or phosphate compounds.

[0003] During the sintering process of the positive electrode material of the battery, a sintering furnace is usually used to mix the raw materials with the solvent to form a slurry. The slurry is coated on the conductive current collector aluminum foil by rolling, scraping and other techniques to form a thin film. The thin film coated on the current collector is dried in an oven to remove the solvent in the slurry, so that the positive electrode material adheres to the conductive current collector, and the dried positive electrode material is sintered. Sintering compacts the material particles, removes residual organic matter, and promotes the grain growth of the active material and the bonding between particles.

[0004] However, after the sintering process, the positive electrode material on the aluminum foil is hot as a whole, which can easily burn the staff. In addition, when the thin film positive electrode material is unloaded, it is easy to cause the thin film positive electrode material to slip, which is very inconvenient when unloading. For this reason, we propose a sintering device for battery positive electrode materials to solve the existing problems. Utility Model Content

The motor is fixed by the mounting column, and the screw is supported by the support plate for rotation.

[0008] Preferably, the upper end of the guide rod is slidably inserted into the threaded slider, and the outer wall of the lifting plate is slidably mounted on the outer wall of the mounting column. The guide rod guides the threaded slider for longitudinal sliding.

[0009] Preferably, an extrusion surface is provided at one end of the mounting column, and an inclined surface is provided between the extrusion surface and the transition surface of the mounting column. During the extrusion process of the passing ball, the extrusion surface reduces the travel resistance of the ball through the inclined surface.

[0010] Preferably, one end of the travel plate is connected to a hydraulic rod 1, the outer wall of the hydraulic rod 1 is sleeved with a mounting plate, and the mounting plate is sleeved on the outer wall of the support rod. The hydraulic rod 1 drives the travel plate to move, and the mounting plate is fixed to the hydraulic rod 1.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. The utility model sintered the dried material on the aluminum foil through a tunnel sintering furnace, and automatically outputted it through a conveyor. The support rollers and support blocks carried the thin film positive electrode material, and cooperated with the liftable stroke plate for secondary load pre-storage. The support rollers were able to move away from each other through a hydraulic rod. The stroke seat was forced to squeeze the spring when passing through the extrusion surface through the elastic member. The stroke seat moved away from each other, and the support blocks located at the four corners of the lower end of the thin film positive electrode material moved out from its lower end, ending the support for the thin film positive electrode material. When the stroke plate was below the support roller, the support roller moved out from below the thin film positive electrode material, and the stroke plate carried the thin film positive electrode material, thereby realizing convenient unloading of the positive electrode material.

Extrusion surface 17, the transition surface between extrusion surface 17 and mounting column 5 is provided with inclined surface, support rod 11 is provided at the upper end of travel seat 15, support block 21 is provided at the upper end of support rod 11, symmetrically distributed travel plate 7 is provided above mounting column 5, support roller 13 equidistantly distributed is rotatably installed at the opposite end of travel plate 7, one end of travel plate 7 is connected with hydraulic rod 12, the outer wall of hydraulic rod 12 is sleeved with mounting plate 14, mounting plate 14 is sleeved on the outer wall of support rod 11, travel rod 18 is provided at one end of travel seat 15, one end of travel rod 18 is slidably installed inside threaded slider 6, spring 19 is provided at one end of travel seat 15, one end of spring 19 is connected with threaded slider 6, and spring 19 is sleeved on the outside of travel rod 18, symmetrically distributed hydraulic rod 22 is provided at the upper end of bottom plate 3, lifting plate 4 is provided at the upper end of hydraulic rod 22, and the outer wall of lifting plate 4 is slidably installed on the outer wall of mounting column 5.

[0021] The implementation steps based on Example 1 are as follows: the conveyor belt in the conveyor 2 is a mesh belt, and the internal pores allow the heat to be effectively transferred to the material being conveyed at the upper end. After the sintering process, the conveyor 2 conveys the thin film positive electrode material to the support block 21, and the support roller 13 at the bottom is supported by rotation. When the four corners of the thin film positive electrode material are all located on the support block 21, the motor 9 drives the screw 10 to rotate, and the threaded slider 6 is guided by the guide rod 16 to slide, so that the threaded slider 6 descends. During this process, the hydraulic rod 22 drives the lifting plate 4 to lift, and stops operating when it is located below the support roller 13 and is about to contact the support roller 13. The hydraulic rod 22 drives the stroke plate 7 to move away from each other and move out the lower end of the thin film positive electrode material. The threaded slider 6 descends through the stroke seat 15. During this process, the ball 20 limits the extrusion surface 17, and the stroke seat 15 is forced to move outward, and then the support block 21 is driven to move outward through the support rod 11, so that the thin film positive electrode material falls onto the lifting plate 4, so that the thin film positive electrode material is conveniently unloaded;

[0022] In this process, the workers are prevented from being scalded by the high-temperature thin-film positive electrode materials. The thin-film positive electrode materials are pre-stored and transported after being piled up in a certain amount, which reduces the labor intensity of the workers. After the lifting plate 4 carries the thin-film positive electrode materials, the lifting plate 4 descends to a preset height, and then the travel seat 15 is reset to achieve continuous reception of the subsequent sintered thin-film positive electrode materials.
