Description

Technical Field

[0001] The present invention relates to the technical field related to vehicle lamp lens detection, and in particular to a method for detecting the surface finish of a vehicle lamp lens. Background Art

[0002] In the process of automobile headlight production, the surface finish of each headlight lens must be tested. The traditional method is to conduct a comprehensive inspection through manual visual inspection. This traditional quality inspection method is prone to deviation and false detection, and is extremely slow and inefficient, which is not conducive to the rapid development of the current automobile industry. In addition, the existing headlight lens surface finish detection method also has instrument detection, but the existing instrument detection only supports a single detection, and the headlight lens needs to be replaced continuously, and the detection efficiency is relatively low. In addition, most of the clamping components can only clamp headlight lenses of a single shape, which makes it inconvenient for the detection device to quickly compare the detection results of headlight lenses of different shapes, greatly reducing the practicality of the detection method. In addition, the existing headlight lens surface finish detection device will have a transmission structure such as a screw, and this structure is mostly used in the clamping component and will be frequently used. Therefore, the transmission structure of the existing detection device lacks a lubrication structure. In most cases, the staff needs to manually oil it, and manual oiling is time-consuming and labor-intensive, which will further reduce the detection efficiency of the headlight lens. At the same time, it also further reduces the staff's experience of using the detection method. Summary of the invention

Then the outer protective shell 219 can transport the fallen lubricating oil to the inner cavity of the oil delivery hole 309 through the lower delivery pipe 310, and the oil delivery hole 309 then transfers the lubricating oil to the surface of the horizontal adjustment screw 208, thereby improving the lubrication degree of the horizontal adjustment screw 208. After the oiling is completed, the outer drive ring 307 and the inner drive ring 308 are loosened. At this time, the elastic force of the support spring 303 can push the oil storage bottle 302 back to the initial position, so that the inner plug 305 can close the outlet below the oil storage bottle 302 again, thereby effectively avoiding the waste of lubricating oil.
