Description

Technical Field

[0001] The utility model relates to the technical field of automobile stamping parts appearance detection, in particular to a stamping parts appearance defect inspection instrument. Background Art

[0002] In the process of automobile design and manufacturing, the stamping of automobile outer covering parts is an important part of the whole vehicle manufacturing. In the stamping process, the appearance inspection of stamped parts is an important step to determine whether the stamping is qualified. Whether the stamped parts are qualified indicates whether the first step of the four major steps in automobile manufacturing has been successfully completed.

[0003] Inspection of stamped parts includes part size inspection and appearance inspection. Appearance inspection is to arrange multiple lamps in regular positions and use the regularity of their light emission to project the black and white stripes on the zebra board onto the surface of the stamped parts. The shape changes of the black and white stripes projected on the parts are used to check whether the stamped parts have defects. However, traditional zebra inspection equipment takes up a large area, and during inspection, it is necessary to adjust the light distribution by moving the parts and zebra boards, which is cumbersome and bulky to operate.

[0004] The existing zebra pattern generator is mainly divided into three parts.

[0005] In the first part, multiple light sources are regularly fixed on the wall or a special rack, and all the light sources are grouped. Each group is controlled to turn on and off separately, thereby controlling the position of the light and shadow of the light source in front of the parts and zebra board.

[0006] In the second part, a zebra board is placed on the side of the light source. The black and white stripes on the zebra board are projected onto the parts through the illumination of the light source, so as to inspect and judge the appearance defects.

[0007] The third part is to place a mobile storage table in front of the light source to facilitate the placement of the stamping parts to be tested. The storage table can be mobile to facilitate the position adjustment of the stamping parts and assist in the adjustment of the relative position between the stamping parts and the zebra plate.

[0008] By changing the position of the light source and adjusting the angle and height of the storage table and zebra board, the inspection of the appearance of stamping parts can be made more convenient and accurate.

[0009] In some special cases, such as when the parts are too large and difficult to move, the appearance inspection is not able to perform well. In the case of inconvenient operation, the appearance inspection results will be greatly affected. Moreover, because the parts are too large, it also means an increase in auxiliary personnel; for example, due to the characteristics of the parts themselves, the strength and rigidity of the parts are poor and it is not easy to move. Improper movement will cause new appearance defects on the stamping parts, or the original appearance defects will be transferred. In this case, the judgment of the appearance of the stamping parts will be greatly affected. Utility Model Content
