Description

Technical Field

[0001] The utility model relates to a helium inspection technology, in particular to a helium inspection tool for a blade battery shell. Background Art

[0002] The blade battery shell is formed by bending thin aluminum plates and then welding them. Due to the limitations of the welding process, there are defects at the welds that may cause leakage. Therefore, after the blade battery shell is welded, the sealing of the welds needs to be tested. Figure 1 As shown, the weld of the entire blade battery occupies the entire length. Since the weld is relatively long and thin, in the prior art, a filling block is generally added inside the workpiece to prevent deformation, the workpiece is manually sealed, and then a manual helium spray test is used for sealing. The loading is complicated, the production cycle is slow, and it is difficult to meet production needs. Utility Model Content

[0003] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the utility model is to provide a helium inspection tool for blade battery housings, which has low cost and high detection efficiency and meets the needs of rapid leak detection in modern industrial production lines.

The helium cover is a hollow body adapted to the blade battery shell, so that when the blade battery shell is tested, the blade battery shell is sleeved outside the helium cover;

[0006] The evacuated base is connected and fixed to the first guide unit and the telescopic unit, so that the evacuated base is driven by the telescopic unit to move up and down along the first guide unit, the evacuated base and the helium cover are located in the same vertical plane, and a sealing ring is fixedly installed on the top surface of the evacuated base, so that after the evacuated base moves upward, a closed cavity is formed between the sealing ring and the blade battery housing;

[0007] The helium hood is connected to the helium filling mechanism, and a long strip opening is provided at the bottom of the helium hood, and the long strip opening is adapted to the weld of the blade battery shell. A plurality of evacuation channels are provided in the evacuation base, and the plurality of evacuation channels are connected to the vacuum pump through an evacuation interface.

[0008] Optionally, the first support frame and the second support frame are respectively fixedly mounted on both ends of the support base, and the second support frame is installed with a first stop block and a second stop block, the first stop block is arranged at the top of the second support frame, and the second stop block is arranged at the middle of the second support frame, and the distance between the first stop block and the second stop block is greater than the width of the helium hood.

[0009] Optionally, a third stop block is installed on the top of the first support frame.
