The role of lithium battery electrolyte is to conduct ions between the positive and negative electrodes and serve as a medium for charging and discharging.

[0019] The present invention aims to provide a post-battery filling process section for use in the field of new energy batteries. This section relates to a sealing machine for the battery after filling, which is used to automatically seal the battery filling port after the filling is completed. Due to the structural characteristics of the battery filling port, the material used in the sealing process is a rod-shaped sealing nail. Therefore, the present invention first needs to solve the problem of accurately inserting the sealing nail into the battery filling port, and secondly, solve the problem of welding and sealing the circular connection between the sealing nail and the battery filling port. Specifically, the present invention uses a horizontally arranged machine as a supporting structure as a whole, and a battery platform is provided in a straight line direction in the middle of the machine. The battery platform is used to carry batteries with seals and drive the batteries to move in a straight line; welding cavities are respectively provided on both sides of the battery platform, and more than two feed ports are provided on the cavity cover plate on the top of the welding cavity to simultaneously place and take out battery cells and sealing nails. The welding cavity is connected to an external vacuum generator. After the battery cells and sealing nails are placed in the welding cavity, the welding cavity is maintained in a vacuum state by vacuuming, and then the sealing nail is inserted into the battery filling port. The sealing nail is inserted in a vacuum environment, which can discharge the gas inside the battery before inserting the sealing nail, thereby avoiding the air inside the battery being squeezed when the sealing nail is inserted, causing the battery to deform.

[0020] Furthermore, the present invention is designed with a battery lifting arm for transferring batteries back and forth between the welding cavity and the battery platform. The battery lifting arm is arranged above the feed port at one end of the welding cavity. In order to facilitate the insertion of the sealing nail into the liquid filling port of the battery, the battery is required to be placed vertically with its liquid filling port facing upward. Based on this assembly requirement, the battery lifting arm of the present invention takes and places the battery in a side suction manner, and completes the battery taking and placing by adsorbing and fixing the side wall of the battery after approaching the side wall of the battery from the outside; specifically, the battery lifting arm uses a lifting arm bracket with a U-shaped frame structure as a bearing structure, and a lifting arm linear module is horizontally provided on the lifting arm bracket to provide horizontal movement power; a plurality of lifting arm slides are connected to the lifting arm linear module, and a lifting arm lifting module is vertically provided on the lifting arm slide, and the vertical movement power is provided by the lifting arm lifting module, and the lifting arm lifting module is provided with an lifting arm head for taking and placing batteries; in the present invention, two groups of lifting arm heads can be provided to transfer batteries from two welding cavities and the battery platform in the middle respectively.

The cam is secured to the side of the second support frame by means of a spring, and the cam is secured to the side of the second support frame by means of a spring.

[0021] Furthermore, the present invention also has a feeding mechanism on the side of the welding cavity, which is used to automatically supply sealing nails. The feeding mechanism is a feeder feeding mechanism, which automatically guides out the sealing nails and then takes them out through the loading mechanism erected above it and transports them into the welding cavity; the loading mechanism uses a loading bracket with a U-shaped frame structure as a bearing structure, and a group of feeding mechanisms are respectively arranged on both sides of the loading bracket, and the loading bracket is provided with two groups of first loading linear modules at intervals in the horizontal direction to respectively supply sealing nails to the two welding cavities; a second loading linear module is provided on the upper edge of the first loading linear module perpendicular to its power direction, and the two provide driving power in the longitudinal and transverse directions in the horizontal plane; the first A loading lifting module is vertically provided on the second loading linear module to provide driving power in the vertical direction to drive the loading assembly arranged thereon to lift and lower; the loading assembly is driven by the loading rotary motor to drive the rotating support and the material picking seat connected thereto to rotate, so as to adjust the angle in the horizontal plane when taking and placing the sealing nails. The material picking seat includes multiple, multiple material picking seats are arranged in parallel and spaced apart to realize the synchronous taking and placing of multiple sealing nails. An air path and a socket are provided inside the material picking seat. During the material picking process, the socket is inserted into the sealing nail, and the sealing nail is fixed in the socket by suctioning air inward. When discharging the material, the sealing nail is pushed outward by blowing air outward through the socket, thereby realizing automatic taking and placing of the sealing nail.

[0022] Furthermore, in response to the assembly process requirements of inserting the sealing nail into the battery filling port, the present invention designs a welding cavity. The welding cavity is a box-shaped structure as a whole, and its top cover is provided with a cavity cover plate. Two feed ports are provided on the cavity cover plate, which are used to take and place batteries and sealing nails respectively. When the batteries and sealing nails to be assembled are loaded into the welding cavity, the closed welding cavity is evacuated by an external vacuum generator, so that the batteries and sealing nails are automatically assembled under a vacuum environment; the special feature is that a transit assembly component and a transfer component are arranged in parallel and spaced apart inside the welding cavity, wherein the transfer component is used to carry multiple batteries at the same time, and the transit assembly component is used to carry multiple sealing nails at the same time, and the transfer component and the transit assembly component respectively drive the batteries and sealing nails to move in a straight line direction, so as to carry out material connection and assembly at different relatively straight line positions, respectively, to avoid motion interference.The side of the transfer assembly component is also provided with a material box, a material picking and turning component and a detection component. After the loading component takes out the sealing pin from the feeding mechanism, it moves to the top of the welding cavity feed port, and places the sealing pin into the material picking and turning component from the feed port. Since the loading component places the sealing pin, the sealing pin is in a vertical state, that is, the loading component places the sealing pin vertically into the material picking and turning component, and the sealing pin needs to be tested before assembly to ensure the sealing degree during subsequent assembly. During the testing process, it is necessary to ensure that the sealing pin is in a horizontal direction. After the testing is completed, the sealing pin is taken out from the material picking and turning component through the transfer assembly component. When assembling the sealing nails, they are in a vertical insertion state, so the sealing nails need to be rotated back to the vertical direction after inspection; based on the incoming direction of the sealing nails, the inspection direction requirements and the requirements of the transfer assembly component for taking the material, the pick-up and placement flipping component of the present invention has a direction flipping function; the special thing is that the material taking and flipping component of the present invention includes two groups of flipping parts. In the actual working process, one of the flipping components is used to receive the sealing nails transported by the feeding mechanism, and the other group of flipping mechanisms can be synchronously inspected by the inspection component. The inspected sealing nails are taken out through the transfer assembly component, that is, the two groups of flipping components complete the process at the same time. The material receiving and inspection material picking actions effectively reduce the workstation standby time and improve the material transfer efficiency; further, the two sets of flip parts adjust their relative positions in the horizontal direction by adjusting the limit parts, so as to align the detection components for detection one by one; the adjustment limit parts use the adjustment cylinder as the power output structure, and the adjustment cylinder is set on a flip slide, and its output end is connected to the other flip slide through the adjustment rod. When the adjustment cylinder outputs power to push the adjustment rod outward, the two flip slides are pushed outward in a straight line at the same time.

[0023] Furthermore, the transfer assembly component of the present invention is used to take out the tested sealing nails from the material picking and flipping component, and at the same time put the defective products into the material box set on the side, and assemble the tested good products into the liquid filling port of the battery; the transfer assembly component uses the first transfer linear module to output linear power to drive the first transfer slide to drive the second transfer linear module set thereon to move linearly, and the second linear module outputs linear power in a direction perpendicular to the first linear module to drive the second transfer slide and the transfer head set thereon to move linearly, thereby realizing the drive of the transfer head in the horizontal plane along the horizontal and longitudinal directions; in particular, the transfer head is connected to the output end of the second transfer linear module with a vertical support plate, and a rotating motor is set on the side wall of the vertical plate to drive the rotating seat of the Z-shaped structure connected to its output end to rotate, so as to connect When feeding, the rotating seat is rotated to the top to receive the material.

After the sealing nail is inserted into the air groove, the sealing nail is fixed by pumping air inward. When assembly is required, the sealing nail is pushed into the liquid filling port of the battery by blowing air outward to complete the automatic assembly of the sealing nail; at the same time, multiple air seats respectively arranged on the outside of the feeding sleeve use their air ports to blow high-pressure gas toward the feeding sleeve during the assembly process, so as to assist assembly and achieve surface cleaning before assembly.

[0024] Furthermore, the present invention is designed with a welding mechanism for welding and sealing the connection between the sealing pin inserted into the battery filling port and the battery.
