[0002] A battery is a device that contains a cup, tank, or other container or part of a composite container that contains an electrolyte solution and metal electrodes to generate an electric current. It is a device that can convert chemical energy into electrical energy. It has a positive electrode and a negative electrode. With the advancement of technology, batteries generally refer to small devices that can generate electrical energy. Using batteries as an energy source can produce an electric current with stable voltage, stable current, long-term stable power supply, and little external influence. It plays a great role in all aspects of modern social life.

[0003] Traditional square battery cutting machines have some shortcomings. When cutting square batteries, workers are required to cut the top cover and bottom cover separately to facilitate the removal of the electrode core. Traditional battery cutting machines need to be operated twice to cut the battery, which requires workers to repeat the cutting operation, making it inconvenient to cut the top cover and bottom cover of the battery.

The ball screw 21 is movably connected to the fixed upper knife seat 4. The lower end of the fixed upper knife seat 4 is fixedly connected to the fixed cutter 11. The outer side of the ball screw 21 is threadedly connected to the screw nut 22. The outer side of the screw nut 22 is fixedly connected to the movable upper knife seat 5. The lower end of the movable upper knife seat 5 is fixedly connected to the movable cutter 16. A downward pressure cylinder 6 is installed at one end of the No. 2 fixed plate 13, and a pressure plate 7 is slidably connected to the inner side of the No. 2 fixed plate 13.

[0021] In this embodiment, the upper end of the No. 3 fixed plate 19 is installed with a No. 2 guide slide 18 near the side of the No. 2 fixed plate 13, one end of the movable upper knife seat 5 is installed at one end of the No. 2 guide slide 18, the upper end of the No. 3 fixed plate 19 is installed with a movable lower knife seat 8 near the side of the No. 2 guide slide 18, the upper end of the No. 3 fixed plate 19 is installed with a fixed lower knife seat 9 near the rear side of the movable lower knife seat 8, the rear end of the fixed lower knife seat 9 is fixedly connected to the No. 1 knife seat adjustment plate 10, the front end of the cutting fixed plate 23 is installed with an electromagnetic brake 14, one end of the No. 2 fixed plate 13 is installed with a No. 1 guide slide 15, the front end of the movable lower knife seat 8 is installed with a No. 2 knife seat adjustment plate 17, the lower end of the downward pressure cylinder 6 is installed at the upper end of the pressure plate 7, the front end of the ball screw 21 is installed at the rear end of the electromagnetic brake 14, and the other end of the No. 1 guide slide 15 is installed at one end of the cutting fixed plate 23.

The movable upper cutter seat 5 can be moved under the guidance of the second guide rail 18 under the drive of the screw nut 22, thereby adjusting the distance between the fixed cutter 11 and the movable cutter 16. When cutting square batteries, the control system controls the hydraulic cylinder 1 to drive the joint 3 downward to extend. Under the connection of the joint 3, the cutting fixed plate 23 moves downward rapidly along the first guide rail 15. The fixed cutter 11 and the movable cutter 16 can cut the top cover and bottom shell of the square battery. By cutting the top cover and bottom cover of the square battery at the same time, the electrode core with recycling value inside the square battery can be easily removed. Compared with the traditional method of crushing the entire battery for recycling, removing the battery core for recycling alone greatly improves the purity of the recycled material, which is of great significance in the retired power battery recycling industry.

[0024] Specifically, the material receiving frame 20 can facilitate the collection of cut waste.

[0025] Working principle:

[0026] When in use, before the square battery is loaded, the height size of the square battery is input into the control system through manual or visual automatic recognition. The control system calculates the appropriate cutting distance between the fixed cutter 11 and the movable cutter 16 and converts it into the number of revolutions to be rotated by the servo motor 12, and drives the ball screw 21 to rotate and drive the screw nut 22 for precise movement. The movable upper knife seat 5 can move under the guidance of the second guide rail 18 under the drive of the screw nut 22, thereby realizing the distance adjustment between the fixed cutter 11 and the movable cutter 16. After the cutting distance is adjusted, the electromagnetic brake 14 is started to hold the ball screw 21 tightly so that it will not rotate during the cutting process to avoid affecting the accuracy of the cutting distance. After the square battery is loaded, the control system controls the downward pressure cylinder 6 to extend, and drives the pressure plate 7 to move down and press the surface of the square battery. When cutting the square battery, the control system controls the hydraulic cylinder 1 The joint 3 is driven downward to extend, and the cutting fixed plate 23 is quickly moved downward along the No. 1 guide rail 15 under the connection of the joint 3. The fixed cutter 11 and the movable cutter 16 can cut the top cover and the bottom shell of the square battery. After the cutting is completed, the control system controls the hydraulic cylinder 1 to drive the joint 3 upward to retract, and the cutting fixed plate 23 is moved upward along the No. 1 guide rail 15 under the connection of the joint 3 until it returns to the initial position. Finally, the control system controls the downward pressure cylinder 6 to retract and drives the pressure plate 7 to move up and away from the surface of the square battery. The cutting of the square battery is completed. The electrode core of the cut square battery is manually removed. By cutting the top cover and the bottom cover of the square battery at the same time, the electrode core with recycling value inside the square battery can be easily removed. Compared with the traditional method of crushing the entire battery for recycling, removing the battery core for recycling alone greatly improves the purity of the recycled material, which is of great significance in the retired power battery recycling industry.
