Description

Technical Field

[0001] This utility model relates to the field of parts inspection technology, specifically to a visual inspection device for automotive parts. Background Technology

[0002] In the production and processing of automotive parts, it is necessary to inspect the parts to determine whether they are qualified. After the inspection, the parts need to be automatically loaded and unloaded. In the automotive seat adjuster, there is a U-shaped part. After the processing is completed, it needs to be visually inspected for missing threads, plastic clips, incorrect spring installation, missing bushings, and missing welds. Because there are many types of inspections and they basically cover all angles of the parts, the existing inspection devices generally use multiple cameras set up around the parts for inspection. Before and after the inspection, manual loading and unloading are used, which is not only complex in structure but also time-consuming and labor-intensive. Utility Model Content

The conveying mechanism includes a gripper, a lifting assembly, a longitudinal moving assembly, and a lateral moving assembly. The gripper is connected to the lifting assembly, the lifting assembly is connected to the longitudinal moving assembly, and the longitudinal moving assembly is connected to the lateral moving assembly. The inspection mechanism includes an inspection camera, a fixing assembly, and a rotating assembly. The inspection camera is connected to the lifting assembly. The fixing assembly is used to fix the parts, and the rotating assembly is disposed on one side of the fixing assembly to drive the parts to rotate. The gripper and the inspection camera are movable above the fixing assembly.

[0004] Furthermore, the transverse component, the longitudinal component, and the lifting component all adopt linear slide modules.

[0005] Furthermore, the conveying mechanism also includes a crossbar connected to the lifting assembly, with gripper cylinders installed at both ends of the crossbar, and grippers installed at the output ends of the gripper cylinders.

[0006] Furthermore, the gripper includes two relatively movable clamping plates, and the clamping plates are provided with multiple clamping bosses.

[0007] Furthermore, the fixing component includes a support column, on which a positioning column is provided.

[0008] Furthermore, a clamping cylinder is provided on the side of the support column, and a pressure plate is provided at the output end of the clamping cylinder.

[0009] Furthermore, the rotating assembly includes a rotating motor, the output end of which is provided with a rotating plate, and the support column and the clamping cylinder are disposed on the rotating plate.

[0010] Furthermore, the detection camera is mounted on the crossbar.

[0011] The advantages of this application are: the provided automotive parts visual inspection device drives the inspection camera to move through the lifting component, longitudinal component and transverse component, and at the same time cooperates with the rotation of the parts, so as to realize the all-round inspection of the parts, such as whether there are missing threads, whether there are plastic clips, whether the springs are installed incorrectly, whether there are missing bushings, and whether there are missing welds; by setting two sets of grippers, one set of grippers completes the unloading while the other set of grippers completes the loading, the loading and unloading are automated, and the inspection efficiency is improved.

[0022] See Figures 1-3This embodiment provides a visual inspection device for automotive parts, including an inspection platform 10. The inspection platform 10 is equipped with a transport mechanism and an inspection mechanism. The transport mechanism includes a first linear slide module 11 arranged laterally, a second linear slide module 12 arranged longitudinally on the slider of the first linear slide module 11, a third linear slide module 13 arranged vertically on the slider of the second linear slide module 12, a crossbar 14 arranged laterally on the slider of the third linear slide module 13, and gripper cylinders 15 respectively arranged at both ends of the crossbar 14. Grippers 16 are arranged at the output end of the gripper cylinders 15.

[0023] Specifically, the grippers 16 at both ends of the crossbar are loading grippers and unloading grippers, respectively. The gripper cylinder 15 is a cylinder that outputs outwards from both ends. The gripper 16 includes a clamping plate 161 set at both output ends. Multiple clamping bosses 162 are set on the inner side of the clamping plate 161. The shape and number of clamping bosses 162 are determined according to the specifications of the parts, thereby achieving stable clamping of the parts.

[0024] The inspection mechanism includes an inspection camera 17, a fixing component 18, and a rotating component 19. The inspection camera 17 is positioned above the unloading gripper. The fixing component 18 includes two sets of spaced support columns 181, each support column 181 is provided with a positioning column 182, and the distance between the two support columns is determined according to the size of the part. An installation groove is opened in the support column, and an inspection sensor 183 is provided in the installation groove to detect whether the part is placed.

[0025] In order to fix the placed parts, clamping cylinders 184 are respectively installed on the sides of the two sets of support columns. The output end of the clamping cylinder 184 is rotatably equipped with a pressure plate 185 through a pin, which is used to press the parts onto the upper surface of the support column.

[0026] The rotating assembly 19 includes a rotating motor 191, a rotating plate 192 is provided at the output end of the rotating motor 191, two sets of support columns 181 and two sets of clamping cylinders 184 are all provided on the rotating plate 192, and the two ends of the rotating plate realize the rotation function through bearings.

[0027] The testing platform 10 is also equipped with a material slide 20, which is inclined downward along the end face of the testing platform 10, and a non-conforming parts frame 21 is set at its bottom.

[0028] Working principle: The first linear slide module 11 and the third linear slide module 13 drive the loading gripper (the gripper on the left in the figure) to grab the parts from the previous process onto the fixed assembly. Then, the clamping cylinder drives the pressure plate to press the parts. After that, the crossbar resets. The first linear slide module 11 and the second linear slide module 12 drive the inspection camera to take pictures of the parts. At the same time, the rotary motor 191 drives the parts to rotate. With the inspection camera taking pictures, the visual inspection of the parts is realized. After the inspection is completed, the unloading gripper grabs the qualified parts onto the conveyor belt on the inspection platform (not shown in the figure). At the same time, the loading gripper completes the loading. Unqualified parts fall into the unqualified parts frame through the material slide.

[0029] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
