Description

Technical Field

[0001] The present invention relates to the technical field of quality inspection, and in particular to a pressure-resistant testing device and method for producing and processing lithium battery shells. Background Art

[0002] The battery shell pressure test device is a device used to detect the battery shell's tolerance to external pressure or electrical pressure. It is mainly used to evaluate whether the battery shell can maintain structural integrity under extreme working conditions and prevent battery leakage or rupture caused by excessive pressure. The test device applies gas pressure or liquid pressure to simulate the mechanical or environmental pressure that the battery may encounter during use. Sensors or monitoring equipment collect real-time data such as deformation, stress, and pressure of the battery shell, and analyze it to determine whether the battery can withstand the predetermined maximum pressure.

[0003] With the existing pressure-resistant testing devices for the production and processing of lithium battery shells, when the lithium battery shells are tested, the lithium battery shells are mostly placed on a workbench for testing and processing. During the test, the lithium battery shells are easily affected by external forces and may be offset or fall off, affecting the processing stability. In addition, the lithium battery shells have different models and sizes, which makes it inconvenient to limit the installation of lithium battery shells of different sizes. At the same time, when the existing pressure-resistant testing devices are tested, in order to compare the test results, most of them need to conduct multiple material tests to facilitate data comparison. However, after a single test is completed, the staff needs to manually take the lithium battery shell for the next test. The work intensity is large, which affects the test efficiency and is inconvenient to perform automatic loading and unloading and alignment tests. Therefore, it is necessary to provide a pressure-resistant testing device and method for the production and processing of lithium battery shells to meet the needs of users. Summary of the invention

[0014] A pressure test method for lithium battery shell production and processing, comprising the following steps:

[0015] S1: Place the lithium battery shells to be tested in the material box, drive the connecting plate to rotate, and move the connecting plate to the left to push the lithium battery shells in the material box out through the push rack on the extension rod, and drop them to the shelf on the installation box on one side for automatic loading;

[0016] S2: Control the installation plate and the supporting plate to rotate.

[0017] S3: The hydraulic cylinder is used to drive the pressing plate to move downward, and the sealing gasket on the pressing plate can fit and press on the lithium battery shell to seal it.

When the moving block moves, it can be limited and moved by the guide block, and at the same time, the moving block can pull the second spring. When the fixed plates on both sides move inward, the installed clamping plates clamp the placed lithium battery shell left and right. When the clamping plates continue to move, they can move smoothly under the guidance of the first guide rod, and the inclined through grooves of the clamping plates can push the clamping blocks to move. The clamping blocks on both sides move inward at the same time, and the clamping blocks can move smoothly under the guidance of the supporting blocks, and the supporting blocks squeeze the third spring.

[0021] 2. When unloading, the lithium battery shell can be stored in the material box, and the second motor on the mounting frame is turned on. The second motor drives the connecting disk to rotate. When the connecting disk rotates, the connecting plate can be driven to move through the mounting rod.

[0022] 3. Turn on the first motor to drive the connecting shaft to rotate. The connecting shaft can drive the mounting plate and the supporting plate to rotate. The push rod on the mounting plate can push the rotating plate to rotate. The rotating plate can drive the turntable on the fixed shaft to rotate.

[0039] Example 2

[0040] like Figures 1 to 11As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment also proposes a pressure test device for the production and processing of lithium battery shells.

[0041] In this embodiment, the connecting shaft 4 is fixedly connected to the center part of the mounting plate 5 and the supporting plate 6, the side end surface of the supporting plate 6 is in contact with the side end surface of the rotating plate 8, the connecting plate 31 is fixedly connected to the mounting rod 32, the mounting rod 32 is rotatably connected to the connecting plate 33, the connecting plate 33 is rotatably connected to the extension rod 34, the rotating plate 8 is provided with grooves at equal angles, the bottom end surface of the rotating disk 10 is in contact with the top end surface of the load-bearing frame 2, which can ensure that the connecting shaft 4 can drive the mounting plate 5 and the supporting plate 6 to rotate smoothly.

The traction rope 18 can be guided and moved by the guide wheel 19 when reeling in. The traction rope 18 can drive the moving block 20 to move inward. The moving block 20 can be limited by the guide block 21 when moving. At the same time, the moving block 20 can pull the second spring 22. When the fixed plates 23 on both sides move inward, the installed clamping plates 27 clamp the placed lithium battery shells on the left and right.

[0043] In this embodiment, a hydraulic cylinder 40 is fixedly connected in the device housing 1, and a pressure plate 41 is fixedly connected at one end of the hydraulic cylinder 40, and a sealing gasket 42 is fixedly connected to the pressure plate 41. The third spring 24 is symmetrically distributed on the left and right sides of the fixed plate 23.

When moving, the moving block 20 can be limited and moved by the guide block 21. At the same time, the moving block 20 can pull the second spring 22. When the fixed plates 23 on both sides move inward, the mounting plate 23 on both sides moves inward. The installed clamping plate 27 clamps the placed lithium battery shell on the left and right. When the clamping plate 27 is driven by the fixed plate 23 to continue to move, the clamping plate 27 can move smoothly under the guidance of the first guide rod 28, and a through groove is provided on the clamping plate 27. The inner side of the through groove is inclined. Therefore, under the movement of the clamping plate 27, the clamping plate 27 can push the clamping block 26 to move through the inclined through groove. At this time, the clamping blocks 26 on both sides move inward at the same time. The clamping block 26 can move smoothly under the guidance of the supporting block 25, and the supporting block 25 squeezes the third spring 24. The clamping blocks 26 on both sides can clamp and limit the placed lithium battery shell front and back, thereby improving the stability of the clamping limit and avoiding offset during testing that affects the test effect.

When the unloading plate 36 moves, it can be guided by the second guide rod 38 in the material box 37 to move smoothly. The unloading plate 36 can push down the lithium battery shell after the test. Under the inclination of the guide plate 47, the falling material slides on the guide plate 47, which is convenient for subsequent collection and improves the loading and unloading effect.

[0047] When testing the lithium battery shell, the operation of the hydraulic cylinder 40 in the device housing 1 can be controlled through the control panel 39. The hydraulic cylinder 40 can drive the pressure plate 41 to move downward, and fit the sealing gasket 42 on the pressure plate 41 to the lithium battery shell. When pressing down, the turntable 10 can be lifted and supported under the support of the load-bearing frame 2, and the lithium battery shell is sealed and protected. Then the air pump 43 is controlled to run, and the gas delivery pipe 44 and the air intake pipe 45 are used to convey gas to the lithium battery shell. The air pressure is monitored by the installed air pressure sensor 46. The air pressure in the lithium battery shell is continuously increased by the pressure until the explosion-proof line on the surface of the lithium battery shell is broken, so that the lithium battery shell can be subjected to a pressure resistance test. After the pressure plate 41 moves up and resets, it drives the mounting block 13 and the storage rack 14 to reset under the push of the first spring 12, and can push out the tested lithium battery shell for subsequent unloading and removal.
