Vehicle lamp air tightness detection system

Abstract

The invention discloses a vehicle lamp air tightness detection system. The vehicle lamp air tightness detection system comprises an air tightness detection machine and a fixing device; an air inlet gun is communicated with an air inlet of a vehicle lamp, and a pressure detector is communicated with a pressure detection port of the vehicle lamp; a spacer is arranged on a baseboard, the air inlet gun and the pressure detector are arranged on the periphery of the spacer, and a fixture and a plug are also arranged on the periphery of the spacer; the air inlet gun, the pressure detector, the fixture and the plug are each arranged on the corresponding support; a horizontal substrate of the supports is laid on the baseboard, and a vertical substrate of the supports is vertically arranged on the baseboard; one side edge of the horizontal substrate is closely attached to the bottom of the vertical substrate, and a first groove extending in the x axis direction is formed in the horizontal substrate; a second groove extending in the y axis direction is formed in the bottom of the vertical substrate, a second bolt is arranged on the side face, where the side edge is located, of the horizontal substrate, and the second bolt is arranged on the second groove in a penetrating mode; a third groove extending in the z axis direction is formed in the vertical substrate, and a third bolt is arranged in the third groove in a penetrating mode; an inserting hole matched with the first bolt is formed in the baseboard.

Description

technical field [0001] The invention relates to a vehicle lamp air tightness detection system. Background technique [0002] As an indispensable part of a car, car lights play the role of night lighting, traffic signals, and anti-collision in bad weather. However, due to factors such as materials and craftsmanship, car lights have airtightness problems such as gaps and leakage. Affect the function of the lights. To this end, we need to strengthen the detection of the airtightness of the lights. At present, many car lamp companies will use the air tightness testing machine to test the car lights. The air tightness testing machine will deliver gas to the car lights, and judge the airtightness of the car lights by detecting whether the car lights are leaking. However, the lamp needs to be fixed during the inspection. The air inlet gun and pressure gauge of the air tightness testing machine need to be aligned with the air inlet and pressure measuring port on the lamp respectiv...

AI Technical Summary

Problems solved by technology

However, the lamp needs to be fixed during the inspection. The air inlet gun and pressure gauge of the air tightness testing machine need to be aligned with the air inlet and pressure measuring port on the lamp respectively. Other air outlet holes on the lamp also need to be sealed. In order to ensure that the air intake gun will not leak air when it supplies air to the lights, but different types of lights have different shapes and sizes, and the positions of the air inlet, pressure measuring port and air outlet are also different, and the existing fixture , intake guns, pressure gauges or plugs are all set on fixed equipment, which can only be adapted to a certain type of car lights, so that each type of car lights must make new fixed equipment, which not only increases the investment and cost, not economical enough, a waste of resources, not environmentally friendly
