The invention discloses an identification device for air tightness detection of vehicle lamps, which comprises a worktable, an air source and an airtight machine. The worktable is provided with a bracket fixedly connected with an inflation cylinder for inflating into lamps, an airtight fixture positioned under the inflation cylinder and a first electromagnetic valve connected with the inflation cylinder, wherein the first electromagnetic valve is communicated with the air source through an air delivery pipe, the airtight machine is electrically connected with a time relay for setting inflation time, the first electromagnetic valve and a sensor for detecting gas pressure in the lamps, the worktable is also provided with a second electromagnetic valve electrically connected with the airtight machine, the second electromagnetic valve is communicated with the inflation cylinder through an air pipe, and a push rod of the cylinder is connected with an identification component for forming identification on the lamps. The qualification rate of the lamps in mass air tightness detection can reach 100 percent through the identification device.
Description
technical field [0001] The invention relates to a lamp for an automobile, in particular to an airtight detection and marking device for an automobile lamp. Background technique [0002] With the continuous improvement of people's living standards and quality, more and more people own cars. Therefore, the performance requirements for cars are also constantly improving. As one of the accessories of the car, lamps not only beautify the car, but the more important function of the lamp is to provide lighting for the driving car in the case of insufficient visible light, or provide warning signals for pedestrians or vehicles, so that The car achieves the purpose of safe driving, so lamps are an indispensable part of the car. In the manufacturing process of automobile lamps, in order to ensure their quality, airtight testing is usually required. Airtight qualified lamps can prevent rainwater and other objects from entering the interior of the lamps, and avoid damage to electrical ...
