The positioning clamping mechanism is installed on the rotating disk and is used to clamp the product on the circumferential surface inspection station. The rotating disk is used to drive the clamped product to rotate. The circumferential surface detection mechanism is arranged on one side of the rotating mechanism, and is used for visually detecting the circumferential surface of the product driven to rotate by the rotating disk after taking a photo; A conversion mechanism is provided between the qualified product discharge hopper and the unqualified product discharge pipe to realize corresponding receiving conversion when the qualified products and unqualified products are discharged.

[0017] like Figure 7 As shown, the product distribution and material distribution mechanism includes a distribution cylinder 16, a guide rail 14 and a distribution plate 15. The distribution plate is connected to the guide rail. The distribution cylinder drives the distribution plate to move forward and backward along the slide rail. Two product push grooves are correspondingly opened on the distribution plate. Before and after the distribution cylinder is extended and retracted, the two product push grooves are alternately connected to the output end of the vibration plate and the product, and the products after docking are pushed to the upper and lower surface detection stations of the double station line respectively. Sensors are set on the distribution plate corresponding to the two product push grooves. After the sensor senses the product, the distribution cylinder drives the distribution plate to move forward and backward to distribute the product to the front and rear two stations in turn.

[0018] The upper and lower surface inspection mechanism includes a transparent inspection platform, and an upper surface visual inspection mechanism and a lower surface visual inspection mechanism respectively arranged on and below the transparent inspection platform. The upper surface visual inspection mechanism and the lower surface visual inspection mechanism respectively include a lifting cylinder, a lifting platform driven by the lifting cylinder, and an industrial camera fixedly installed on the lifting platform. After the product arrives at the transparent inspection platform, the industrial camera in the upper and lower surface inspection mechanism starts to take pictures to detect defects on the upper and lower surfaces of the product. The product has two upper surfaces. When inspecting the upper surface of the product, the upper industrial camera needs to move up and down through the lifting platform.

[0019] The transverse movement manipulator comprises a transverse movement track, a transverse movement cylinder and a pneumatic clamping claw. The transverse movement cylinder drives the pneumatic clamping claw to move along the transverse movement track.

[0020] The circumferential surface detection mechanism includes a three-axis adjustment mechanism and an industrial camera. The industrial camera adjusts the position of the circumferential surface of the product for shooting by the industrial camera through the three-axis adjustment mechanism.

[0021] After the upper and lower surface defects of the product are detected, the transverse robot moves the product to the rotating mechanism. After the product is positioned and clamped, the rotating mechanism rotates, and the industrial camera of the circumferential surface detection mechanism detects the circumferential surface defects of the product. After the circumferential surface defect detection is completed, the transverse robot moves the product to the unloading position.

[0022] The qualified product discharge hopper and the unqualified product discharge pipe are correspondingly arranged below the discharge position. The qualified product discharge hopper is connected to the offset cylinder and driven to move in and out of the discharge position by the offset cylinder. A qualified product material frame 11 is arranged below the qualified product discharge hopper. If the product is a qualified product, the offset cylinder extends to guide the product into the qualified product material frame through the qualified product discharge hopper. If the product is an unqualified product, the product is dropped into the unqualified product discharge pipe by the transverse robot.

[0025] When the present invention is used, the vibrating plate is used for loading. The operator delivers the product to be tested to the vibrating plate, and at the same time takes away the qualified product in the qualified product frame at the lower material position and the unqualified product in the unqualified product frame after classification.

[0026] Connect the output end of the vibration plate to the product push slot on the dividing plate of the product dividing and material dividing mechanism. Sensors are set corresponding to the two product push slots on the dividing plate. After the sensors sense the products, the dividing cylinder drives the dividing plate to move forward and backward to divide the products into two front and rear workstations in turn.

[0027] After the product arrives at the transparent inspection table, the industrial cameras in the upper and lower surface inspection mechanisms begin to take pictures to detect defects on the upper and lower surfaces of the product. The product has two upper surfaces. When inspecting the upper surface of the product, the upper industrial camera needs to move up and down through the lifting platform.

[0028] After the upper and lower surface defects of the product are detected, the transverse robot moves the product to the rotating mechanism. After the product is positioned and clamped, the rotating mechanism rotates, and the industrial camera of the circumferential surface detection mechanism detects the circumferential surface defects of the product. After the circumferential surface defect detection is completed, the transverse robot moves the product to the unloading position.

[0029] If the product is a qualified product, the offset cylinder extends to guide the product to the qualified product material frame through the qualified product discharge hopper. If the product is an unqualified product, the product is dropped into the unqualified product discharge pipe by the transverse robot.

[0030] After the unqualified products fall, the rotating rack driven by the rotating cylinder drives the sorting and unloading tube to switch between the two unqualified product positions, and the two unqualified product frames are respectively set up corresponding to the two unqualified product frames. The two unqualified product frames correspond to two different types of unqualified products: those with defects on the upper and lower surfaces and those with defects on the circumferential surface.
