Description

Technical Field

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

[0002] In the production and processing of automotive parts, it is necessary to inspect the parts to determine their qualification. After inspection, the parts need to be automatically loaded and unloaded. In the automotive seat adjuster, there is a U-shaped part. After processing, it is necessary to inspect whether the inner hole diameter is missing, whether the concentricity of the inner hole is qualified, and whether the curvature of some structures meets the requirements. At the same time, visual inspections are also required, such as whether there are missing threads, plastic clips, whether the springs are installed incorrectly, whether there are missing bushings, and whether there are missing welds. Among these, the inspection of the inner hole is generally done manually, which is not only prone to errors but also inefficient. Since there are many types of visual 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 inspection, manual loading and unloading are used, which is not only complex in structure but also time-consuming and labor-intensive. Utility Model Content

This application will now be described in detail with reference to the accompanying drawings and embodiments. See also Figure 1 This embodiment provides a multifunctional inspection device, including an inspection platform 10. The inspection platform 10 is divided into two inspection areas: the left side is the mechanical inspection device area and the right side is the visual inspection device area. A conveying device is set between the two inspection areas to realize the transfer of parts from the mechanical inspection area to the visual inspection area, as well as the final automated unloading.

[0024] The conveying device includes a multi-axis moving platform, which can move in three directions: X, Y, and Z. Specifically, it 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 arranged at both ends of the crossbar 14. Grippers 16 are arranged at the output end of the gripper cylinders 15.

[0025] Specifically, the gripper on the left side of the crossbar is a loading gripper, and the gripper on the right side is a unloading gripper. 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.

[0026] The visual inspection device includes an inspection camera 17, a second fixing mechanism 18, and a rotating mechanism 19. The inspection camera 17 is mounted on a gripper cylinder above the unloading gripper. The second fixing mechanism 18 includes two sets of spaced support columns 181. Each support column 181 is equipped with a positioning column 182. 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 installed in the installation groove to detect whether the part is placed.

[0027] 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, which is used to press the parts onto the upper surface of the support column. The pressure plate 185 achieves the rotation function through multiple pins and connecting parts.

[0028] The rotating mechanism 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.

[0029] 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.

[0030] Specifically, the mechanical testing device includes a first fixing mechanism 22 and a first testing mechanism 23. The first fixing mechanism 22 and the second fixing mechanism 18 have the same structure, which will not be described in detail here. The first testing mechanism 23 includes a plurality of first cylinders 231 arranged circumferentially along the first fixing mechanism. The output ends of the plurality of first cylinders are respectively provided with inner hole testing rods 232. In this embodiment, according to the model of the part, four sets of first cylinders 231 are arranged, two sets on each side of the part, for testing whether the inner hole of the part is qualified and whether it meets the concentricity requirements.

[0031] In addition to inspecting the inner hole of the part, there is a connector at the lower end of the part that needs to be inspected for position and curvature. Therefore, a second cylinder 233 and a third cylinder 234 are also provided on the side of the part. The output end of the second cylinder 233 is provided with a curvature detection rod 235, and an arc-shaped detection groove 236 is opened on the arc-shaped detection rod 235. If the connector can be inserted into the arc-shaped detection groove, it is qualified. The output end of the third cylinder 234 is provided with a position detection rod 237. The position detection rod 237 is moved to the connection point to determine whether its position is qualified.

[0032] Working principle: The operator places the part to be inspected on the first fixed mechanism 22 and then presses it. The first cylinder 231, the second cylinder 232 and the third cylinder 233 drive the inspection rod to inspect the mechanical structure of the part. After the inspection is completed, the pressing cylinder is released, and the multi-axis moving platform drives the loading claw to pick up the part and move it to the second fixed mechanism 18, and then press it. Then the crossbar is reset, and the first linear slide module 11 and the second linear slide module 12 drive the inspection camera to take pictures of the part. At the same time, the rotary motor 191 drives the part to rotate, and together with the inspection camera to take pictures, the visual inspection of the part is realized. After the inspection is completed, the unloading claw grabs the qualified part to the conveyor belt on the inspection platform (not shown in the figure), and at the same time the loading claw completes the loading. The unqualified part falls into the unqualified part frame through the material slide.

[0033] 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.
