Airtightness detection device and method for fixture of filling machine

Abstract

The invention relates to an airtightness detection method and system for a fixture of a filling machine. The system comprises a base and a bracket fixed on the base, the base is provided with an installation groove matched with the fixture in size, the bracket is provided with an airtightness detection device, a pressure regulation mechanism and a vacuum generation device, the airtightness detection device comprises a cylinder, an elastic air faucet connected with a piston end of the cylinder, and a control mechanism used for controlling the movement of the cylinder, the elastic air faucet is arranged opposite to an air faucet of the fixture, and the pressure regulation mechanism, the vacuum generation device and the airtightness detection device are mutually communicated through a tee joint and a pipeline. The airtightness detection device, the pressure regulation device and the vacuum generation device fixed on the base and the bracket achieve the airtightness detection of the fixture, air leakage in the detection process of the fixture is avoided, and the production efficiency of a battery is remarkably improved.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to an airtight detection device and a detection method for a fixture of a liquid injection machine. Background technique [0002] At present, during the use of the clamps of the liquid injection machine produced, it is easy to cause aging and damage of the seals, which in turn leads to poor sealing of the clamps, resulting in a series of problems of liquid leakage and non-injection. Since the airtightness of the fixture of the liquid injection machine is unknown during the maintenance process, it is generally necessary to use manual maintenance methods, that is, use tools such as wrench, diagonal pliers, flat-head screwdriver, scissors, and inner hexagon to seal all the seals on the fixture. All joints are tightened on one side. This method not only has a large workload, but also has low efficiency. It may also cause missed inspection due to negligence, so that the quality...

Since the airtightness of the fixture of the liquid injection machine is unknown during the maintenance process, it is generally necessary to use manual maintenance methods, that is, use tools such as wrench, diagonal pliers, flat-head screwdriver, scissors, and inner hexagon to seal all the seals on the fixture. The joints are all tight on one side. This method not only has a large workload, but also has low efficiency. It may also cause missed inspection due to negligence, so that the quality of spare parts cannot be guaranteed.
