AI Technical Summary
The existing battery cell classification machine cannot lock when the air source is cut off, resulting in insufficient air pressure in the jaw cylinder and unable to clamp the battery cell, which poses a risk of the battery cell falling.
A five-port, three-position solenoid valve is used to increase the central closing position, so that the clamping cylinder can still maintain air pressure when the air source is cut off, and the splint can continue to clamp the battery core.
This reduces the risk of the battery core falling off on the clamping jaw cylinder, ensuring that the battery core can be effectively clamped even if the air source is abnormal.

DETAILED DESCRIPTION
[0022] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0023] The following is combined with Figure 1-4 This application is described in further detail.
[0024] A battery cell grading machine includes a support frame 10 and a manipulator 3. The manipulator 3 is arranged on the support frame 10. A mounting frame 6 is fixedly provided on the manipulator 3. The mounting frame 6 is fixedly provided with a pneumatic cylinder 5. There are multiple pneumatic cylinders 5 arranged on the mounting frame 6.
[0025] The telescopic shaft of the pneumatic cylinder 5 is fixedly connected to the mounting plate 7, the mounting plate 7 is connected to the buffer assembly, the buffer assembly is connected to the fixing plate 13, the fixing plate 13 is fixedly connected to the clamping cylinder 8, the clamping cylinder 8 is fixedly connected to the clamping plate 16, the clamping plate 16 clamps the battery cell 9, and the inner side of the clamping plate 16 is fixedly provided with an anti-skid plate 15, the anti-skid plate 15 presses against the battery cell 9, and the anti-skid plate 15 has an anti-slip effect on the battery cell 9.
[0026] Two groups of buffer assemblies are provided on the mounting plate 7. The two groups of buffer assemblies are respectively provided on both sides of the mounting plate 7. The buffer assemblies include a guide rod 12 and a buffer pad 11. The mounting plate 7 is fixedly provided with a fixed tube 22. The guide rod 12 is inserted into the fixed tube 22. One end of the guide rod 12 is fixedly connected to the fixed plate 13. The buffer pad 11 is fixedly connected to the end of the guide rod 12 away from the fixed plate 13. The buffer pad 11 is pressed against the fixed tube 22. The guide rod 12 and the buffer pad 11 play a buffering role when the pneumatic cylinder 5 carries the clamping cylinder 8 up and down.
[0027] A mounting box 2 is fixedly provided on the manipulator 3, and a five-port, three-position solenoid valve 1 is provided in the mounting box 2. One end of the solenoid valve 1 is connected to an air pipe 4, and the other end is connected to an air source 19. The end of the air pipe 4 away from the solenoid valve 1 is connected to the clamping cylinder 8. When the air source 19 abnormally interrupts the air supply, the five-port, three-position solenoid valve 1 adds a middle closed position, so that the cylinder can still maintain air pressure when the air source 19 is shut off, and the clamp 16 continues to clamp the battery cell 9.
[0028] The cross section of the clamping plate 16 is in the shape of a "[" character, which facilitates the limited clamping of the battery cell 9. The clamping cylinder 8 is fixed with a buffer rod 14. There are multiple buffer rods 14 on the clamping cylinder 8. The clamping cylinder 8 is made of soft rubber. When the clamping cylinder 8 approaches the battery cell 9 and the clamping plate 16 clamps the battery cell 9, the buffer rod 14 can buffer the force between the top of the battery cell 9 and the clamping cylinder 8, thereby preventing the battery cell 9 from being damaged.
[0029] A connecting plate 17 is provided on the fixed plate 13, and a scanner 18 is fixedly provided on the connecting plate 17. The scanning head of the scanner 18 is facing the direction of the battery cell 9. The scanner 18 is electrically connected to the manipulator 3. When the gripper cylinder 8 clamps the battery cell 9, the scanner 18 scans the QR code information on the battery cell 9, and the manipulator 3 rotates to place the battery cells 9 on different trays according to safety level.
[0030] A sensor 21 is fixedly provided on the mounting plate 7, a fixing rod 20 is fixedly connected to a guide rod 12 in a group of buffer assemblies, the buffer pad 11 is between the guide rod 12 and the fixing rod 20, the fixing rod 20 is in front of the sensing head of the sensor 21, and the sensor 21 is electrically connected to the manipulator 3. When the manipulator 3 moves down and approaches the battery cell 9, the gripper cylinder 8 presses against the battery cell 9, the manipulator 3 continues to move down, the guide rod 12 moves in the fixing tube 22, and the fixing rod 20 approaches the sensor 21. When the fixing rod 20 moves in front of the sensing head of the sensor 21, the manipulator 3 stops moving down to prevent the battery 9 from being damaged by overvoltage.
[0031] The implementation principle of this embodiment is: when the air source 19 of the clamping cylinder 8 is cut off or in an abnormal situation, because a five-port three-position solenoid valve 1 is used, a middle closed position is added to the solenoid valve 1, so that the clamping cylinder 8 can still maintain the pressure of the clamping cylinder 8 when the air source 19 is cut off, and the clamping plate 16 continues to clamp the battery cell 9, thereby reducing the risk of the battery cell 9 on the clamping cylinder 8 falling off, thereby achieving the effect of reducing the risk of the battery cell 9 falling off.
