Description

Technical Field

[0001] The utility model belongs to the technical field of production and processing of wire harness terminals, and particularly relates to an airtight detection device for wire harness terminals. Background Technique

[0002] Some wire harness terminals need to be subjected to airtight detection at the time of leaving the factory to prevent water ingress. In the prior art, the airtight detection equipment for wire harness terminals generally consists of a positioning tooling for positioning and making the space to be detected of the wire harness terminal form a closed space, a fixing component for fixing the wire harness terminal in the positioning tooling, and an airtight detector. When in use, the wire harness terminal to be detected is placed on the positioning tooling and fixed by the fixing component, and then the airtight detector is started for detection.

[0003] The inventor found in daily production that for the airtight detection equipment of wire harness terminals with multiple positioning toolings, when picking up the wire harness terminals after the detection is completed, the common practice is to take down multiple at a time. In this way, because force is required in the process of taking down from the positioning tooling, the wire harness terminals in the hand are likely to fall off and land on the workbench. Then, due to the size of the workbench itself and the bounce of the wire harness terminals, etc., the wire harness terminals are likely to fall, either fall from a height and be damaged, or fall into the blind area of vision after falling.

Among them, the positioning block 2 is fixed on the upper layer of plate body, and the fixed mold group is fixed on the lower layer of plate body.

[0027] Among them, the fixed mold group includes a first lifting assembly 4 and a pressing block 6 arranged on the output end of the first lifting assembly 4. The first lifting assembly 4 can control the pressing block 6 to fix the wire harness terminal 3 on the positioning block 2.
