Apparatus for detection of multifunctional car light airtightness and bearing

Abstract

The invention discloses a multifunctional air-tightness and bearing testing device for automobile lamps, comprising a square main test cavity which is hollow and has an opening on the upper top surface. An air inlet and an air outlet arranged on the side face of the main test cavity can be respectively connected with a gas source and a display instrument, and the opening on the upper top surface of the main test cavity is provided with a sealing ring which is matched with a test template. Quick clamps for sealing are also arranged on the two opposite side walls of the main test cavity. The multifunctional air tightness and bearing testing device can quickly and effectively test the air tightness and bearing status of the automobile lamps with simple structure, convenient operation and a plurality of test functions.

Description

technical field [0001] The invention relates to a device for detecting the airtightness and safety of a car lamp, which belongs to the technical field of car lamp manufacturing. Background technique [0002] At present, during the use of automobile lamps, the phenomenon of poor air tightness and water leakage often occurs in the lamps. The reasons are: first, the rubber cups used for lamp sealing have poor pressure bearing performance, resulting in air leakage of the lamps. The sealing of the car lamp is usually achieved by the cooperation of a rubber cup and the lamp housing of the car lamp to prevent water from entering the interior of the lamp body. In the manufacturing process of car lights, the airtightness test of the car lights is carried out. In the conventional airtightness test process, in order to avoid the cup being ejected by the air pressure when inflated, it is necessary to apply external force to the rubber cup to complete the airtightness. sex test.

AI Technical Summary

Problems solved by technology

However, this operation can only detect the sealing performance of the lamp, and cannot detect the pressure state that the rubber cup used for sealing can withstand. It is difficult to eliminate the safety hazards existing in the use of the lamp and affect its normal service life. ; Second, the poor sealing of the light adjustment mechanism of the automobile lamps and lanterns, resulting in water leakage of the lamps

The reason is that the mechanism requires multiple parts to cooperate with each other. If the cooperation is not proper, the lamp body will leak air, causing water to enter the lamp body of the car lamp, which affects the normal light direction of the lamp.

In its conventional airtightness testing, the testing process is complex and lacks accurate testing data, which makes the product prone to potential safety hazards
