Abstract

The invention discloses a welding airtightness detecting device of a battery box. The detecting device comprises a detection bench arranged on a rack; a plurality of detection stations are arranged onthe detection bench; and an elastic base plate is arranged on the surface of the detection bench. A battery box is arranged on the elastic base plate of the corresponding the detection station. A punching cylinder is arranged above each detection station; when the punching cylinder is pressed down, the battery box is buckled on the elastic base plate in an airtightness manner; a pressurization air pipe connected to the inner cavity of the battery box and a pressure sensor are arranged on the elastic base plate of each detection station; the pressurization air pipe is used for leading compressed gas in the battery box; and the pressure sensor is used for detecting the air pressure of the inner cavity of the battery box and a display terminal is connected to the output terminal of the pressure sensor. According to the invention, a test problem of airtightness of the battery box is solved. The welding airtightness detecting device having advantages of simple operation, quick detection and accurate determination is suitable for batched detection.

Description

technical field [0001] The invention relates to equipment for storing sheet metal in metal machining, in particular to a battery box welding air tightness detection device and a detection method thereof. Background technique [0002] At present, the use of lithium-ion batteries is becoming more and more widespread. It is well known that lithium-ion batteries in the field of electric vehicles are gradually replacing the leading position of lead-acid nickel-chromium batteries due to their advantages of small size, light weight, environmental protection and reusability. [0003] Traditional battery boxes do not meet airtight requirements, but some electric vehicles on the market, especially scooters, have airtight requirements for battery box shells, especially where the charging and discharging ports need to meet airtight requirements. At present, in more and more designs of battery case shells, the consideration of airtightness in the overall structure is added, and the optim...
