Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of vehicle lamp detection, and in particular relates to a device for detecting the missing installation of a ventilation cap of a vehicle lamp. Background Art
[0002] Since the car lights are filled with inert gas, they need to be sealed. However, the gas inside the car lights will expand due to the heat radiation of the car lights, causing the air pressure inside the car lights to increase. Therefore, a breather cap needs to be installed on the car to ensure that the gas is discharged when the air pressure inside the car lights rises, so as to avoid excessive pressure inside the car lights.
[0003] The patent number is 201910711371.3, and a public specification published on February 2, 2021 discloses a vehicle lamp assembly missing assembly detection device, including a device body and a tooling fixture. The device body includes a cabinet and a display panel, a three-color light, a gas-electric interface, a starting switch, and an electrical cabinet arranged on the cabinet. The tooling fixture includes a fixed plate and a gas-electric connector, a clamping cylinder, a laser sensor, and a protective film affixing mechanism arranged on the fixed plate. The tooling fixture is fixed to the device body through the fixed plate, and the product to be inspected is fixed on the clamping cylinder. The laser sensor is arranged near the product to be inspected. The gas-electric connector of the tooling fixture is connected to the gas-electric interface of the device body. When in use, the product to be inspected is placed on the tooling fixture, the starting switch is pressed, and the clamping cylinder clamps the product on the tooling. The controller in the electrical cabinet outputs a detection signal to the laser sensor. The laser sensor detects whether the parts are missing. The entire detection process replaces manual inspection and improves the product's factory quality.
[0004] In the above-mentioned prior art, the vehicle lamp is fixed by a fixture, and the ventilation cap is detected by a three-color lamp and a laser sensor. However, the three-color lamp and the laser sensor cannot effectively distinguish the color difference between the ventilation cap and the lamp body, which may easily cause misjudgment.
