Description

Technical Field

[0001] The invention relates to the technical field of explosion-proof valve testing, and in particular to a lithium battery explosion-proof valve testing device. Background Art

[0002] The lithium battery explosion-proof valve is a key safety component of lithium batteries. It is in the form of a sheet. During normal use of the battery, if the internal pressure changes due to factors such as ambient temperature changes, short circuits, overcharging, etc., the explosion-proof valve can be opened in time to release the pressure to avoid battery explosion. The explosion-proof valve needs to be tested for good quality during production, and then the explosion-proof valve testing device needs to be used to prevent defective products from entering the market;

[0003] When using the explosion-proof valve test device, the explosion-proof valve needs to be fixed first, and then the two sides of the explosion-proof valve need to be inspected for defects. However, the existing explosion-proof valve test device is found to have no function of turning over the explosion-proof valve. After the defect inspection on one side is completed, it is necessary to manually release the fixation and then turn the explosion-proof valve over and then fix it again before the defect test can be performed on the other side. This seriously affects the test efficiency, so it needs to be improved.

[0055] The use process of the present invention is as follows: when the explosion-proof valve body 10 needs to be tested for good products, the explosion-proof valve body 10 is placed on the placement block 52 on the left, and then the motor 38 is controlled to rotate forward, and the forward rotation of the motor 38 drives the rotating shaft 3 40 to rotate. Since the bevel gear 1 41 and the sleeve 43 are connected to the rotating shaft 3 40 through a one-way bearing, the sleeve 43 rotates when the motor 38 rotates forward, and the bevel gear 1 41 does not rotate. The rotation of the sleeve 43 drives the chain 2 45 to rotate, and the rotation of the chain 2 45 drives the rotating block 4 to rotate, so that the bottom plate 5 and the two shells 6 can be rotated, so that the shell 6 on the left side moves to the right, and the shell 6 on the right side moves to the left, so that the two shells 6 are swapped, and then the explosion-proof valve body 10 just placed is moved to the right. While moving, the two pistons 1 9 will move toward the middle under the action of the auxiliary components, so that the two moving rods 1 12 and the two clamping blocks 11 can move toward the middle, so that when moving to the right, the two clamping blocks 11 just clamp and fix the explosion-proof valve body 10;

[0056] When the housing 6 on the left side moves to the right side, the second rotating shaft 17 on the housing 6 will also move accordingly. When the housing 6 moves to the right side, the pin block 15 is just located in the through slot 18 on the second rotating shaft 17. Figure 1 , 3 , as shown in 5;

[0057] Then control the motor 38 to reverse, the same principle is that the bevel gear 41 rotates, the sleeve 43 does not rotate, the rotation of the bevel gear 41 drives the bevel gear 2 42 to rotate, the rotation of the bevel gear 2 42 drives the reciprocating screw 24 to rotate, the rotation of the reciprocating screw 24 drives the sliding seat 25, the outer frame 26, the flaw detector 27 and the CCD high-definition camera 28 to move to the left first, and during the movement to the left, the flaw detector 27 can perform defect detection on one surface of the explosion-proof valve body 10, when the flaw detector 27 and the CCD high-definition camera 28 completely scan one surface of the explosion-proof valve body 10, the leftward movement of the sliding seat 25 ends, and then the sliding seat 25, the outer frame 26, the flaw detector 27 and the CCD high-definition camera 28 will move to the right, and when moving to the right, the outer frame 26 will contact with the protrusion 20, so that the push block 22, the push rod 19 and the protrusion 20 can be pushed to the right. Since the protrusion 20 is embedded in the spiral groove 21, when the protrusion 20 moves to the right, the shaft 14 can be rotated, and the rotation of the shaft 14 drives the pin block 15 to rotate, and the rotation of the pin block 15 drives the shaft 2 17 to rotate, and the rotation of the shaft 2 17 drives the two chains 1 33 to rotate, so that the two boxes 1 8 can be rotated, and the rotation of the two boxes 1 8 drives the two moving rods 12 and the two blocks 11 to rotate, thereby driving the explosion-proof valve body 10 to rotate, and when the sliding seat 1 25 and the outer frame 26 and other components move to the right after the stroke is completed, the explosion-proof valve body 10 just rotates half a circle, so that the explosion-proof valve body 10 can be turned over;

[0058] When the sliding seat 1 25 moves to the right, it will move to the left, and the outer frame 26, the flaw detector 27 and the CCD high-definition camera 28 will also move to the left. Then, the same principle can be used to detect defects on the other side of the explosion-proof valve body 10, thereby completing the good product test of the explosion-proof valve body 10;

[0059] Since a spring 23 is designed between the protrusion 20 and the support plate 2, the spring 23 is compressed when the push block 22, the push rod 19 and other components move to the right, so that when the sliding seat 25 and other components move to the left, the spring 23 rebounds and the push block 22, the push rod 19, the protrusion 20 and other components move to the left and reset, wherein the pin block 15 is connected to the rotating shaft 14 through a one-way bearing, so when the protrusion 20 moves to the left, the rotating shaft 14 rotates without causing the pin block 15 to rotate, thereby preventing the box body 8, the moving rod 12, the explosion-proof valve body 10 and other components from rotating;

[0060] The flaw detector 27, the CCD high-definition camera 28 and the buzzer 36 are all electrically connected to the central processor 35, and the CCD high-definition camera 28 is electrically connected to the display screen 37. When the flaw detector 27 detects that there is a defect on the surface of the explosion-proof valve body 10, the signal can be transmitted to the central processor 35, and then the central processor 35 can control the buzzer 36 to work, thereby reminding the staff to pay attention, so that the staff can know that the explosion-proof valve body 10 cannot pass the good product test. At the same time, the central processor 35 can also control the CCD high-definition camera 28 to work, so that when the flaw detector 27 detects a defect, the CCD high-definition camera 28 can immediately take a picture of the defective part, and then transmit it to the display screen 37 for display, so that the staff can view it conveniently;

[0061] When testing the first explosion-proof valve body 10, the explosion-proof valve body 10 can be manually placed on another placement block 52. When the test of the first explosion-proof valve body 10 is completed, the motor 38 is controlled to rotate forward to exchange the positions of the two shells 6, so that the second explosion-proof valve body 10 can be moved to the right side, and then the good product test and flipping are performed according to the same principle. Since there are auxiliary components in the two shells 6, the explosion-proof valve body 10 can be automatically fixed when the shell 6 moves from the left side to the right side, and can be automatically released when it moves from the right side to the left side. The following is a detailed description taking a single auxiliary component as an example;

[0062] In the process of moving from the left side to the right side, the first gear 68 will mesh with the gear ring 31, so that the first gear 68 can make the rotating shaft 4 67 and one of the reciprocating screws 2 62 rotate, and then under the action of the chain 3 66, the rotation of one of the reciprocating screws 2 62 can make the other reciprocating screw 2 62 rotate together, thereby realizing the simultaneous rotation of the two reciprocating screws 2 62, and the rotation of the two reciprocating screws 2 62 can make the two sliding seats 2 63 and the two pull rods 64 move downward first, and when moving downward, the disc 50 and the moving rod 2 49 can be pulled downward, so that the moving rod 2 49 can be moved away from the rubber pad 51, and the spring 2 53 is stretched, wherein the moving rod 2 49 moves downward and the piston 2 48 can also move downward, and then under the action of the two pipes 60, the downward movement of the piston 2 48 can make the air in the box body 2 46 enter the two box bodies 1 8, thereby making the two pistons 1 9 move toward the middle, so that When moving to the right side, the two clamping blocks 11 can just clamp and fix the explosion-proof valve body 10. Due to the design of magnet one 55 and magnet two 56, the placement block 52 will not move downward when the sliding seat two 63, the disc 50, the moving rod two 49, the piston two 48 and other components just move downward. When the two clamping blocks 11 contact and clamp the explosion-proof valve body 10, that is, when the downward movement of the sliding seat two 63 ends, the tension exerted on the spring two 53 reaches the maximum and is greater than the suction force between the magnet one 55 and the magnet two 56. In this way, when the two clamping blocks 11 just clamp and fix the explosion-proof valve body 10, the spring two 53 can pull the placement plate and the rubber pad 51 downward, so that the placement block 52 does not contact the explosion-proof valve body 10, and the magnet one 55 is separated from the magnet two 56. In this way, when the explosion-proof valve body 10 is turned over, the explosion-proof valve body 10 can be guaranteed to rotate normally.

[0063] When the second spring 53 pulls the placement plate and the rubber pad 51 downward, the rubber pad 51 will contact with the top of the second moving rod 49, which can reduce the impact force. At the same time, the placement block 52 moves downward, and the two limit rods 57 and the two iron blocks 58 also move downward, so that the iron blocks 58 can be close to the third magnet 59. Then, under the action of the suction force, the placement block 52 and the rubber pad 51 can be prevented from suddenly jumping upward when the rubber pad 51 just contacts the second moving rod 49.

[0064] In the process of moving from the right side to the left side, the first gear 68 meshes with the ring gear 31 again, so that the two reciprocating screws 62 continue to rotate, and then the two sliding seats 63 will move upward, so that the pull rod 64, the disc 50, the moving rod 49, the piston 48, the rubber pad 51, the placement block 52, the magnet 56 and other components can be moved upward and reset, wherein the piston 48 moves upward to suck back the air in the two boxes 8, and then the two pistons 48, the two moving rods 12 and the two blocks 11 move outward, thereby releasing the fixation of the explosion-proof valve body 10, so that the explosion-proof valve body 10 can fall on the placement block 52 during the movement to the left side, and then the explosion-proof valve body 10 can be caught, and when moving to the left side, the tested one can be manually removed and a new one can be placed, and then the test can be continued with the same principle.

[0065] The above are only preferred embodiments of the present invention. Any person skilled in the art may modify the present invention by using the above technical solutions or modify it into an equivalent technical solution. Therefore, any simple modification or equivalent replacement made according to the technical solution of the present invention belongs to the scope of protection claimed by the present invention.
