Airtightness detection device for new energy battery shell

Abstract

The invention discloses an airtightness detection device for a new energy battery shell, and relates to the technical field of airtightness detection. The problem that the sealing performance is pooris solved. The airtightness detection device specifically comprises a shell body, four second electric telescopic rods are welded to the inner wall of the top of the shell body, a same adjusting frameis fixed to the outer walls of the bottoms of every two second electric telescopic rods through hinges, a sliding groove is formed in the inner wall of the bottom of each adjusting frame, two or moresliding rods are fixed to the inner wall of each sliding groove through screws, and the outer wall of each sliding rod is slidably connected with a sealing frame. According to the invention, the adjusting frame is arranged; a new energy battery shell is placed below the adjusting frame; and then the adjusting frame is moved downwards until the pressure detection heads make contact with the top ofthe new energy battery shell, the fifth electric telescopic rods are started to stretch out and draw back continuously until the pressure detection heads are inserted into the leakage holes in the new energy battery shell, then the two sixth electric telescopic rods are controlled to push the sealing rings to block the leakage holes, and sealing is completed.

Description

technical field [0001] The invention relates to the technical field of airtight detection, in particular to an airtight detection device for a new energy battery casing. Background technique [0002] With the continuous development of science and technology, people are investing more and more in environmental protection. A large number of new energy vehicles have been produced. The battery pack is an important part of new energy vehicles. It has a dedicated battery pack casing, so the safety of the battery pack casing Gradually highlighted, because it directly affects the safety of the whole vehicle; therefore, the design requirements for the strength, rigidity, heat dissipation, waterproof, insulation, etc. It is very important; in order to better protect the battery pack, an airtight detection device for the new energy battery casing is needed to detect the airtightness of the battery casing. [0003] After searching, the Chinese application publication number is CN108956...

AI Technical Summary

Problems solved by technology

The airtight detection device for new energy battery casings in the above-mentioned patents has the following disadvantages: the leak hole on the upper surface of the housing is pressed and sealed by the downward pressure cylinder and the second blocking block, but this is on the upper surface of the housing. Under the premise that the leakage hole is facing the second blocking block, if the leakage hole cannot be aligned with the second blocking block, the casing cannot be well sealed, so there is still a problem that the second blocking block can only move up and down. Can't plug the leak well
