After battery assembly, the electrolyte is quantitatively injected into the battery. This process involves two steps: first, injecting the electrolyte into the battery; and second, ensuring the injected electrolyte thoroughly wets the internal electrodes and separator. The immersion time affects the production cost of lithium-ion batteries. After electrolyte injection, the injection port and battery surface must be cleaned to remove any residual electrolyte or other substances before proceeding to the next welding and sealing process to seal the injection port.

[0003] Based on the sealing process after battery liquid filling, the sealing pin needs to be inserted into the battery liquid filling port during the sealing process, and then the sealing pin is welded to the edge of the liquid filling port for sealing. In order to prevent the battery from deforming due to the compression of internal gas during the insertion of the sealing pin into the battery liquid filling port, a battery sealing pin assembly cavity that can provide a vacuum state needs to be designed.

[0014] A battery sealing machine that includes a battery sealing nail assembly cavity.

[0015] The beneficial effects of this utility model are as follows:

[0016] This utility model addresses the deficiencies and shortcomings of existing technologies by independently developing and designing a battery sealing nail assembly cavity and its battery sealing machine that enables the sealing nail to be inserted under vacuum, effectively reducing battery deformation caused by internal air pressure during insertion, and integrating automatic battery carrying, sealing nail transfer detection and insertion functions, thereby effectively improving the sealing nail insertion efficiency.

[0017] This utility model aims to provide a battery electrolyte filling process section applicable to the field of new energy batteries, belonging to the battery electrolyte filling port sealing mechanism. Its function is to insert sealing nails into the battery electrolyte filling port after electrolyte filling. The utility model has a box-shaped structure, with a cavity cover plate on the top. The cavity cover plate has two feeding ports, one for picking up and placing the battery and the other for placing the sealing nail. After the battery and sealing nail to be assembled are put into the welding cavity, the closed welding cavity is evacuated by an external vacuum generator, so that the battery and sealing nail are automatically assembled in a vacuum environment. The special feature is that the utility model has a transfer assembly component and a transfer component arranged in parallel at intervals inside. The transfer component is used to carry multiple batteries at the same time, and the transfer assembly component is used to carry multiple sealing nails at the same time. The transfer component and the transfer assembly component drive the battery and sealing nail to move in a straight line, so that they can be received and assembled at different relative straight positions, avoiding motion interference.The side of the transfer assembly component also features a material box, a material picking and flipping component, and a detection component. After the feeding component removes the sealing nail from the feeding mechanism, it moves to above the inlet of the welding cavity and places the sealing nail into the material picking and flipping component from the inlet. Since the feeding component places the sealing nail vertically, the sealing nail is placed vertically into the material picking and flipping component. Before assembly, the sealing nail needs to be detected to ensure the sealing performance during subsequent assembly. During the detection process, the sealing nail must be kept horizontal. After detection, the sealing nail is removed from the material picking and flipping component by the transfer assembly component. When installing the sealing nails, they are inserted vertically, so the inspected sealing nails need to be rotated back to a vertical position. Based on the requirements for the incoming and inspecting directions of the sealing nails, as well as the material handling direction of the transfer assembly component, the pick-up and flipping component of this invention has a direction flipping function. The key feature is that the pick-up and flipping component of this invention includes two sets of flipping parts. In actual operation, one set of flipping parts is used to receive the sealing nails transported by the feeding mechanism, while the other set of flipping parts can be simultaneously inspected by the inspection component. The inspected sealing nails are then removed by the transfer assembly component, meaning both sets of flipping parts operate simultaneously. The material receiving and inspection processes are completed, effectively reducing station standby time and improving material transfer efficiency. Furthermore, the two sets of tilting components adjust their horizontal relative positions via adjustable limit components to sequentially align with the inspection components. The adjustable limit components use an adjusting cylinder as the power output structure. The adjusting cylinder is mounted on one tilting slide, and its output end is connected to the other tilting slide via an adjusting rod. When the adjusting cylinder outputs power to push the adjusting rod outward, it simultaneously pushes both tilting slides outward in a linear motion. When the adjusting cylinder drives the adjusting rod to retract inward, the two tilting slides retract... The two slide blocks are brought closer together, and the position of the two slide blocks is adjusted by a single power output. At the same time, a first support is provided at the inner end of each of the two slide blocks, and a second support is provided at the outer end of each of the two slide blocks. A first limiting post and a second limiting post are provided on the side wall of the first support and the second support, respectively, to limit the inner and outer positions of the slide blocks. Two sets of flipping components are respectively set on the two slide blocks. The flipping components are powered by a flipping motor to rotate the first or second rotating material picking head in order to adjust the material picking and dispensing direction and the direction of the sealing nail, so as to facilitate material picking and dispensing and inspection.

Furthermore, the two sets of tilting components adjust their horizontal relative positions via adjustable limit components to sequentially align with the inspection components. The adjustable limit components use an adjusting cylinder as the power output structure. The adjusting cylinder is mounted on one tilting slide, and its output end is connected to the other tilting slide via an adjusting rod. When the adjusting cylinder outputs power to push the adjusting rod outward, it simultaneously pushes both tilting slides outward in a linear motion. When the adjusting cylinder drives the adjusting rod to retract inward, the two tilting slides retract... The two slide blocks are brought closer together, and the position of the two slide blocks is adjusted by a single power output. At the same time, a first support is provided at the inner end of each of the two slide blocks, and a second support is provided at the outer end of each of the two slide blocks. A first limiting post and a second limiting post are provided on the side wall of the first support and the second support, respectively, to limit the inner and outer positions of the slide blocks. Two sets of flipping components are respectively set on the two slide blocks. The flipping components are powered by a flipping motor to rotate the first or second rotating material picking head in order to adjust the material picking and dispensing direction and the direction of the sealing nail, so as to facilitate material picking and dispensing and inspection.
