Description

Technical Field

[0001] This utility model relates to the field of visual inspection equipment technology, and in particular to an automotive parts inspection equipment. Background Technology

[0002] With the rapid development of society and the economy, the ownership rate of automobiles is increasing, and the market demand for auto parts is also growing. During the production process, auto parts require extensive testing to ensure product quality. Previously, quality inspection was mainly conducted manually, which was slow and required a large amount of manpower.

[0003] Currently, most companies have made improvements to address this issue by using visual sensors for quality inspection, thus increasing inspection efficiency. However, most of the steps before and after inspection still rely on manual operation, resulting in low automation and slow production efficiency. Utility Model Content

[0004] To address the problems existing in the prior art, this utility model proposes an automotive parts testing device. The aim is to improve the automation level of the testing equipment, thereby increasing testing and production efficiency while ensuring product quality.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: an automotive parts testing equipment, comprising a frame, wherein a feeding device, a testing device, and a discharging device are sequentially arranged on the upper surface of the frame; the testing device includes a first testing station and a second testing station; the first testing station is provided with a rotary positioning mechanism, and optical fibers are arranged on both sides of the rotary positioning mechanism; the second testing station is provided with a vision testing device; a three-axis transfer robot is arranged between the feeding device and the first testing station; and a double-gripper robot is arranged between the first testing station and the discharging device, wherein the distance between the two grippers on the double-gripper robot is equal to the distance between the first testing station and the second testing station.

[0006] Based on the above, the coordination between the various devices in this utility model makes the product inspection process smoother, improves inspection and production efficiency, reduces manpower consumption, and enhances the overall automation level. When inspecting products, the loading device loads the product, the three-axis transfer robot transports the product to the first inspection station, and the through-beam fiber optic cable detects whether bidirectional drilling has been completed. Then, the dual-gripper robot transports the product to the second inspection station, where the vision inspection device inspects the product's appearance and dimensions. Finally, the dual-gripper robot transports the product to the unloading device. In the actual inspection process, the transfer of the product from the first inspection station to the second inspection station and from the second inspection station to the unloading device are performed simultaneously. This saves energy consumption and improves production efficiency. Finally, the unloading device classifies and collects the products based on the inspection results from the first and second inspection stations. The entire process requires minimal human intervention; only manual removal of the inspected products is necessary.

[0007] Furthermore, the rotary positioning mechanism includes a first rotary motor, a gripper cylinder, and a gripper disposed at the output end of the gripper cylinder. A rotating disk is fixedly mounted on the output shaft of the first rotary motor, and the gripper cylinder is fixedly mounted to the rotating disk.

[0008] Based on the above, the gripper cylinder controls the gripper to clamp the product, the first rotary motor drives the product to rotate through the rotary disk, and at the same time, the through-beam optical fiber performs hole detection to determine whether the holes on both sides are completed.

[0009] Furthermore, the visual inspection device includes a rotating frame, an upper camera, and a side camera. The upper camera is positioned directly above the rotating frame, and the side camera is positioned at the side end of the rotating frame and faces the rotating frame.

[0010] Based on the above, the product inspected at the first inspection station is transferred to the rotating frame by the dual-gripper robot arm. The rotating frame drives the product to rotate, and the upper camera and the side camera inspect the product's shape and size.

[0011] Furthermore, the dual-gripper manipulator is fixedly mounted on the frame via a mounting base, and the dual-gripper manipulator has a first gripper and a second gripper at both ends.

[0012] Based on the above, the first gripper is used to transfer the product on the first inspection station to the first inspection station, and the second gripper is used to transfer the product on the second inspection station to the unloading device.

[0013] Furthermore, the feeding device includes a vertically arranged NG buffer line and an OK conveyor line. The OK conveyor line is equipped with a rejection device, which is directly opposite the conveyor port of the NG buffer line. The rejection device includes a rejection cylinder and a rejection plate, and the rejection plate is fixedly engaged with the output shaft of the rejection cylinder.

[0014] Based on the above, when a product arrives at the unloading device, the rejection device reacts according to the detection results of the first detection station and the second detection station. When it is determined to be a defective product, the rejection cylinder pushes the rejection plate to push the product to the NG buffer line. If it is a qualified product, the product continues to be transported to the collection device by the OK conveyor line.

[0015] Furthermore, an upper light source is provided below the upper camera, and a side light source is provided in front of the side camera.

[0016] Based on the above, the upper light source and the side light source are used to provide supplementary lighting for the upper camera and the side camera, respectively, thereby improving the accuracy of information acquisition.

[0017] To more clearly illustrate the above-mentioned features of this utility model and the objectives it aims to achieve, the present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments. Attached Figure Description
