The invention provides a battery cover plate turnover and shell entering device in a first aspect. As shown in fig. 1 to 3, the apparatus 100 for turning a battery cover into a case according to the embodiment of the present invention includes a turning assembly 110, a connecting rod assembly 120 and a sliding assembly 130, wherein the turning assembly 110 includes a turning member 111 for fixing the battery cover 500 and a first fixing shaft 112 protruding outward from the turning member 111, the turning member 111 has a first state and a second state, and the second state is a state when the battery cover 500 is aligned with the battery case 400; the connecting rod assembly 120 is used for driving the turnover part 111 to rotate between a first state and a second state; the sliding assembly 130 is connected to the link assembly 120 and forms a track limiting groove 140 through which the first fixed shaft 112 passes, the link assembly 120 is hinged to a portion of the flip 111 passing through the track limiting groove 140, and the sliding assembly 130 is configured to drive the flip 111 to move towards the battery case 400 when the flip 111 rotates from the first state to the second state, so that the battery cover 500 is inserted into the battery case 400.
When assembling the battery cover plate 500 and the battery case 400, firstly, the tab connection piece 410 on the battery cell is in an upright state, the battery cover plate 500 is fixed to the battery cover plate turning-in-case device 100, the battery cover plate 500 is also in an upright state, then the battery cover plate 500 is moved to one side of the tab connection piece 410, the lithium ion battery cover plate 500 and the tab connection piece 410 on the battery cell are welded together, and at this time, the battery cover plate 500 is in a first state, namely, is welded with the tab connection piece 410 and is in an upright state along the vertical direction. Then, the link assembly 120 moves under the action of external force (for example, the driving of the driving mechanism 200) to drive the turnover part 111 to turn over, and in the process of turning over the turnover part 111, because the first fixed shaft 112 slides along the track limiting groove 140, the track limiting groove 140 limits the moving stroke and track of the turnover part 111, so that the turnover part 111 turns over 90 degrees counterclockwise and turns over to the second state, that is, the state when aligning with the battery case 400, the concentricity of the battery cover plate 500 and the battery case 400 is ensured, and accurate alignment of the battery cover plate 500 and the battery case 400 is realized.
As shown in fig. 9, the track-limiting groove 140 includes a first end 141 and a second end 142 extending along the extending direction thereof, and when the battery cover plate 500 is in the first state, the first fixing shaft 112 is located at the first end 141 of the track-limiting groove 140; when the battery cover 500 rotates to the second state, the first fixing shaft 112 slides to the second end 142 of the track-limiting groove 140, and the battery cover 500 is in the second state. After the first fixing shaft 112 slides to the second end 142, the connecting rod assembly 120 cannot move continuously, and at this time, the driving mechanism 200 continues to apply pressure to the connecting rod assembly 120, so that the sliding assembly 130 is driven to slide downwards, the battery cover plate 500 is inserted downwards into the battery shell 400, the battery cover plate 500 can be smoothly inserted into the battery shell 400, the force is easy to control, the battery cover plate 500 does not need to be manually pushed into the battery shell 400, and the success rate of inserting the battery cover plate 500 into the battery shell 400 is improved.
In the process that the battery cover plate 500 is turned over downwards, the battery cover plate 500 pulls the tab connection piece 410 backwards, that is, the battery cover plate 500 is withdrawn relative to the tab connection piece 410, and the tab connection piece 410 falls down towards the sliding assembly 130, so that when the battery cover plate 500 is aligned with the battery case 400, the tab connection piece 410 is in a horizontal state, and then when the battery cover plate 500 is inserted downwards into the battery case 400, the tab connection piece 410 can be clamped between the battery cover plate 500 and the battery case 400 in a horizontal state. In the process of pulling the tab connecting piece 410 by the battery cover plate 500, because the root of the tab connecting piece 410 is fragile, if the pulling direction and angle have deviation, the root of the tab connecting piece 410 is easy to break, so that the tab is torn, and the track limiting groove 140 of the embodiment of the invention limits the moving track of the battery cover plate 500, limits the angle and direction of pulling the tab connecting piece 410 by the battery cover plate 500, and avoids damaging the tab.
The embodiment of the invention completely avoids manual intervention, ensures the unification of standard actions of products in the production process, improves the product yield, is suitable for high-speed mass production equipment aiming at the laser welding and shell entering process of the battery cover plate 500 and the lug connecting sheet 410, realizes the rapid turnover and shell entering actions, and meets the standardized operation.

When the link assembly 120 is pressed downward by the driving mechanism 200, the link assembly 120 can rotate relative to the first connecting member 131 to turn the turnover member 111, and at this time, the sliding member 150 does not move and is limited to the rotation of the link assembly 120. When the first fixed shaft 112 slides to the second end 142 of the track-limiting groove 140, the turnover part 111 is limited from sliding continuously, and the connecting rod assembly 120 connected with the first fixed shaft 112 cannot move continuously. If the driving mechanism 200 continues to press the connecting rod assembly 120 downwards, the sliding member 150 is driven to slide downwards along the frame 160, and the turnover member 111 moves downwards along with the sliding member 130 and is inserted into the battery housing 400. The structural design of this embodiment is ingenious, and through the cooperation of upset subassembly 110, link assembly 120 and sliding component 130, the three actions of the upset of accomplishing battery apron 500, back-off, income shell are realized on a station, very big saving the cost, improved production efficiency, further promote the yields.
