Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of auxiliary tools for welding and feeding of automobile parts, in particular to a visual inspection device for feeding of automobile parts. Background Art
[0002] Due to the large consumption of automobiles, automobile parts are usually processed and manufactured in an automated production and processing system. During the welding process of automobile parts, a conveyor line is usually used to transport the parts to the designated position, and then an automatic robot clamps the parts and places the parts on the workbench of the welding equipment. Before the automatic robot takes the parts out of the conveyor line, a detection device is required to detect the specific position of the parts. The detection device commonly used now is a visual inspection device. An industrial camera is set up above the conveyor line to determine the position of the parts. However, due to the unique shape of the parts, when the automatic robot clamps them, it is necessary to locate the clampable parts on the parts. A single industrial camera can accurately locate the clamping parts on the parts for parts neatly placed on the conveyor line. However, if the parts are tilted or offset when placed on the conveyor line, it is impossible to rely on a single industrial camera to accurately locate the clamping parts. Utility Model Content

Shooting from three angles ensures the position of the auto parts on the conveying equipment 1, as well as the inclination angle of the auto parts themselves, and thus accurately locates the clamping parts on the auto parts. Electric slide rails 12 and angle adjustment components 13 are set to adjust the position and angle of the mounting plate two 14, and then adjust the position and angle of the industrial camera three 15. For different types of auto parts, because their clamping parts are different, the position and angle of the industrial camera three 15 can be adjusted to ensure that the industrial camera three 15 can shoot the clamping parts;
[0020] A fill light 5 is fixedly installed at the bottom of the mounting base 3. There are two fill lights 5, which are symmetrically arranged on the left and right sides of the industrial camera 4 to assist the industrial camera 4 in shooting.

The second mounting plate 14 is fixedly mounted on the rear end of the rotating plate 1304. The rotating shaft 1303 is driven to rotate by the motor 1301, thereby driving the rotating plate 1304 to rotate, so as to adjust the position and angle of the second mounting plate 14.
[0024] A fill light 3 16 is fixedly installed on the bottom of the mounting plate 2 14 to assist the industrial camera 3 15 in shooting.
[0025] Working principle: When in use, the auto parts are placed on the conveying equipment 1 for transportation, and are photographed when passing through the shooting areas of industrial camera 1 4, industrial camera 2 9, and industrial camera 3 15. The three angles ensure that the clamping positions on the auto parts can be photographed, and then the clamping parts on the auto parts are accurately located, making it easier for the loading robot to load the auto parts.
[0026] Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of the present invention.
