Description

Technical Field

[0001] This invention belongs to the field of battery drying equipment, and particularly relates to a battery cell baking oven in which the opening and closing of the door is synchronized with the positioning of the battery cells. Background Technology

[0002] In existing battery production lines, the produced cells need to be pressurized and baked to remove moisture. Baking requires a sealed space for heating and insulation. However, in current technologies, the opening and closing of the oven door and the fixing of the cells are not synchronized. For example, in existing technologies, the opening and closing of the oven door is generally controlled manually or by electronic equipment. A robotic arm transports the cells into the oven, where a fixing device secures them. After fixing, the door is closed for baking. The lack of coordination between these two processes reduces the baking and drying efficiency of the oven, increases equipment costs, and ultimately affects the production efficiency of the cells, reducing the product's market competitiveness.

In addition, the first sliding sleeve 1313 and the second sliding sleeve 1323 slide on the door guide rod 16, restricting the movement direction of the first door 151 and the second door 152, so that the first door 151 and the second door 152 can move along the direction of the door guide rod 16. The staggered arrangement of the first door 151 and the second door 152 ensures that the first baking space 11 and the second baking space 12 do not interfere with each other when the battery cells are placed or removed.

[0078] During the operation of this cell baking oven, the fixing and removal of the cells in the first baking space 11 and the second baking space 12 are performed alternately, for example: When the battery cell is fixed in the first baking space 11, the first driving device 1215 drives the first lifting plate 1211 to descend, so that the first lower heating plate 12142 moves away from the first upper heating plate 12144, and the first door 151 opens (rises). After the robot arm places the battery cell on the first lifting shaft 12145, the first driving device 1215 drives the first lifting plate 1211 to rise, so that the first lower heating plate 12142 moves closer to the first upper heating plate 12144, and the first door 151 closes (descends) to carry out the heating process. After baking is completed, the first driving device 1215 drives the first lifting plate 1211 to descend, so that the first lower heating plate 12142 moves away from the first upper heating plate 12144, and the first door 151 opens (rises). The robot arm then moves the battery cell on the first lifting shaft 12145 out of the first baking space 11.

[0079] When the battery cell is fixed in the second baking space 12, the second drive device 1225 drives the second lifting plate 1221 to descend, so that the second lower heating plate 12242 moves away from the second upper heating plate 12244, and the second door 152 opens (rises). After the robot arm places the battery cell on the second lifting shaft 12245, the second drive device 1225 drives the second lifting plate 1221 to rise, so that the second lower heating plate 12242 moves closer to the second upper heating plate 12244, and the second door 152 closes (descends) to carry out the heating process. After baking is completed, the second drive device 1225 drives the second lifting plate 1221 to descend, so that the second lower heating plate 12242 moves away from the second upper heating plate 12244, and the second door 152 opens (rises). The robot arm then moves the battery cell on the second lifting shaft 12245 out of the second baking space 12.

[0080] In actual device operation, the first baking space 11 and the second baking space 12 operate alternately. For example, when the first door 151 is opened to place the battery cell, the second door 152 is closed; when the second door 152 is opened to place the battery cell, the first door 151 is closed. Since the first door 151 and the second door 152 are staggered when they open and close, they do not interfere with each other.
