Technical Field

[0001] The utility model relates to the technical field of casing presses, in particular to an automatic casing press for lithium battery production. Background Technique

[0002] A lithium battery is a type of battery with a lithium metal or lithium alloy as the positive / negative electrode material and using a non-aqueous electrolyte solution. During the production of lithium batteries, a casing needs to be set up to protect the lithium batteries. Generally, the casing is divided into an upper casing and a lower casing. In order to lock the buckle between the upper casing and the lower casing, a casing press is generally used for auxiliary pressing.

[0003] The existing casing presses usually place the lower casing with the lithium battery fixed on the processing table, and join the upper casing and the lower casing together. Then, a hydraulic cylinder is used to drive the casing pressing plate to apply pressure to the upper casing, so that the buckle between the upper casing and the lower casing is locked. However, the existing casing presses are not convenient for quickly discharging the lithium batteries that have completed casing pressing during use, thus affecting the sustainable operation of the casing press.

[0004] Therefore, technical personnel in this field have proposed an automatic casing press for lithium battery production to solve the problems raised in the above background. Content of the Utility Model

Detailed Description of the Invention

[0019] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0020] Please refer to Figures 1-3, An automatic shell pressing machine for lithium battery production, including a processing table 1; brackets 3 are arranged on both sides of the processing table 1, a mounting plate 4 is installed on the brackets 3, a cylinder 5 is installed in the middle of the mounting plate 4, and a shell pressing plate 6 is installed at the bottom of the cylinder 5. A processing groove 7 is opened in the middle of the processing table 1, rotating seats 8 are arranged at both ends of the processing groove 7, the rotating seats 8 are hinged with rotating plates 9, and placing frames 10 that can be mutually attached are installed at the approaching ends of the two rotating plates 9. The placing frames 10 are used for placing the upper shell and the lower shell. A driving component for driving the rotating plate 9 to rotate is arranged at the bottom of the processing table 1. A bottom frame 2 is installed at the bottom of the processing table 1, a receiving frame 17 is installed at the bottom of the bottom frame 2, a limiting groove 18 is opened in the receiving frame 17, and a receiving cylinder 19 is placed in the limiting groove 18; by placing the spliced lower shell and upper shell in the placing frame 10, the cylinder 5 is pushed to lower the shell pressing plate 6 for pressing, so that the buckle between the upper shell and the lower shell is locked. After the shell pressing is completed, the driving component is used to make the rotating plate 9 rotate downward, so that the lower shell and the lower shell in the placing frame 10 fall into the receiving cylinder 19 placed in the receiving frame 17, thereby realizing automatic and convenient discharging.

[0021] The driving component includes fixing plates 12 installed on both sides of the bottom of the processing table 1. A bidirectional screw 13 is rotatably arranged between the two fixing plates 12. Moving frames 14 are threadedly connected to both sides of the bidirectional screw 13. One end of a connecting rod 15 is hinged to the moving frame 14, and the other end of the connecting rod 15 is hinged to the rotating plate 9. A motor 16 connected to the bidirectional screw 13 is installed on the fixing plate 12. After the shell pressing is completed, the motor 16 is started, and the motor 16 drives the bidirectional screw 13 to rotate, so that the two moving frames 14 move away from each other. The rotating plate 9 is driven to rotate downward through the connecting rod 15, and then the placing frames 10 on the two rotating plates 9 are separated. At this time, the lower shell and the upper shell originally located in the placing frame 10 will fall downward, and the falling upper shell and lower shell will fall into the receiving cylinder 19.

[0022] Limit blocks 11 are installed at both ends of the processing groove 7 for restricting the upward rotation of the rotating plate 9. When the rotating plate 9 contacts the limit blocks 11, the rotating plate 9 is in a horizontal position. At this time, the placing frames 10 on the two rotating plates 9 will be attached.

[0023] Through holes 20 are opened on both sides of the top of the receiving cylinder 19.

[0024] Infrared transmitters 21 and infrared receivers 22 are respectively arranged on both sides of the top of the receiving frame 17.

[0025] A controller 23 is installed on the inner wall of the bottom frame 2.

[0026] The infrared emitter 21, the infrared receiver 22, and the through hole 20 have the same height. The feeding situation in the feeding cylinder 19 can be detected through the infrared receiver 22, the infrared emitter 21, and the through hole 20. The infrared emitter 21 emits infrared rays, and the infrared receiver 22 receives signals. When the feeding cylinder 19 is filled with the lower and upper shells after the shell pressing is completed, the infrared receiver 22 cannot receive signals. At this time, the controller 23 will receive the signals and give a reminder through a warning light or making a sound, so as to let the worker replace the new feeding cylinder 19.

[0027] The working principle of the present utility model is as follows: When in use, in the initial state, the two rotating plates 9 in the processing groove 7 are horizontally arranged. At the same time, the placing racks 10 installed at the adjacent ends of the two rotating plates 9 are spliced together, and the feeding cylinder 19 is placed in the limiting groove 18 of the feeding rack 17. The lower shell with the fixed lithium battery is placed in the placing rack 10, and the upper shell is placed on the lower shell, so that the upper shell and the lower shell are spliced together. Then, the air cylinder 5 is started, and the air cylinder 5 drives the shell pressing plate 6 to descend. By applying a pressing force through the shell pressing plate 6, the buckle between the upper shell and the lower shell is locked, and the shell pressing operation is completed. After the shell pressing is completed, the motor 16 is started, and the motor 16 drives the bidirectional screw 13 to rotate, so that the two moving racks 14 move away from each other. The rotating plate 9 is driven to rotate downward through the connecting rod 15, and then the placing racks 10 on the two rotating plates 9 are separated. At this time, the lower shell and the upper shell originally located in the placing rack 10 will fall downward, and the falling upper shell and lower shell will fall into the feeding cylinder 19, thus realizing automatic and fast discharging. Further, the feeding situation in the feeding cylinder 19 can be detected through the infrared receiver 22, the infrared emitter 21, and the through hole 20. The infrared emitter 21 emits infrared rays, and the infrared receiver 22 receives signals. When the feeding cylinder 19 is filled with the lower and upper shells after the shell pressing is completed, the infrared receiver 22 cannot receive signals. At this time, the controller 23 will receive the signals and give a reminder through a warning light or making a sound, so as to let the worker replace the new feeding cylinder 19.

[0028] In the present utility model, the spliced lower shell and upper shell are placed in the placing rack 10, and the shell pressing plate 6 is pushed down by the air cylinder 5 for pressing, so that the buckle between the upper shell and the lower shell is locked. After the shell pressing is completed, the rotating plate 9 is driven to rotate downward through the driving component, so that the lower shell and the lower shell in the placing rack 10 fall into the feeding cylinder 19 placed in the feeding rack 17, thus realizing automatic and convenient discharging. Further, the feeding situation in the feeding cylinder 19 can be detected through the infrared receiver 22, the infrared emitter 21, and the through hole 20.
