Description

Technical Field

[0001] The invention relates to the technical field of ceramic detection, in particular to a ceramic crack detection device. Background Art

[0002] The Chinese utility model patent with publication number CN221231085U discloses a device for automatically detecting the quality of ceramics. The front side of the ceramics is detected by a front visual detection mechanism, and the transfer mechanism moves the ceramics from the weighing mechanism to the top of the back visual detection mechanism. The back visual detection mechanism detects the back side of the ceramics. If the weight and visual detection are both qualified, the transfer mechanism moves the ceramics to the feed end of the qualified product conveying mechanism, otherwise, the transfer mechanism moves the ceramics to the feed end of the unqualified product conveying mechanism for conveying. The utility model can automatically detect the surface defects on the front and back sides of the product and the weight of the product according to the program settings, thereby improving the detection efficiency. At the same time, a transfer mechanism, an unqualified product conveying mechanism and a qualified product conveying mechanism are set to sort unqualified products in time, further improving the detection efficiency.

[0003] In the related art, after ceramic products are manufactured, their quality generally needs to be inspected, such as crack detection. Traditional inspection methods mostly use manual naked eye inspection. In order to improve its work efficiency and inspection effect, existing inspection methods usually use inspection equipment for inspection. For example, the Chinese utility model patent with publication number CN221231085U uses two sets of industrial cameras to inspect the top and bottom of the ceramic product, and then transfers and unloads the inspected product through a transfer mechanism. However, this inspection method has fewer inspection directions and lacks the function of all-round inspection, so it can only be applied to sheet or disc-shaped ceramic products, and cannot perform comprehensive inspection on cylindrical ceramic products. It lacks the function of inspecting cracks all over the ceramic product. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the deficiencies in the prior art, the present invention provides a ceramic crack inspection device, which drives a fixed ceramic product to be transported longitudinally through a longitudinal reciprocating component.

Through the setting of an adjustment component, the ceramic product during the transportation process can be tilted and rotated, which facilitates the second industrial vision camera group to detect cracks in different ranges and angles of the ceramic product, and fully utilizes the driving force for the transportation of the ceramic product. There is no need to additionally set up an electric rotating part to rotationally drive the ceramic product, thereby improving the energy saving and environmental protection of the inspection equipment, and solving the problem of lack of the function of inspecting the entire body of the ceramic product, thereby reducing the inspection effect of the ceramic product.

In conjunction with the second industrial vision camera group 72, the ceramic product can be visually inspected all over, thereby increasing the inspection range of the ceramic product and making full use of the driving force for the transportation of the ceramic product. There is no need to set up an additional electric rotating part to drive the ceramic product to rotate, thereby improving the energy saving and environmental protection of the inspection equipment.

The specific shape is shown in the attached Figure 7 and Fig. 9 As shown, the universal shaft in the prior art is adopted by the connecting shaft 752, so that when the vacuum suction cup 744 drives the ceramic product to adjust the angle, it can be synchronously driven to rotate, thereby improving the range and angle of subsequent detection;

[0057] The arrangement of the telescopic rod 757 facilitates the electric cylinder 745 in the mechanical arm 74 to better drive the vacuum suction cup 744 to move downward to pick up and place ceramic products.

[0058] The guide groove 7510 is arranged in a downward and upward tilted manner, so that when the protruding rod 759 moves downward along the guide groove 7510, it can drive the L-shaped telescopic plate 758 and the telescopic rod 757 to move downward in sequence, and then drive the driving plate 756 and the bottom end of the connecting shaft 752 to move in a fan shape, thereby driving the ceramic product fixed by the vacuum suction cup 744 to perform a tilting movement, so that the second industrial vision camera group 72 can visually detect cracks on the lower outer surface of the ceramic product and the ground. It not only has the function of detecting multiple surface cracks, but also can cooperate with the rotation of the ceramic product to form a wide range of tilt angle detection, further improving the detection effect, and fully utilizing the driving force for the transportation of ceramic products to form an automatic adjustment function.

[0061] The second motor 61 is connected to an external power source and a control switch, is a forward and reverse motor, and is configured using a connection method and an encoding method of the prior art, and is used to drive the first bevel gear 62 to rotate;

[0062] One of the transmission rollers of the two conveying assemblies is fixedly connected to a transmission shaft 63, and one end of the two transmission shafts 63 is fixedly connected to a second bevel gear 64 meshing with the outer surface of the first bevel gear 62, and the two second bevel gears 64 are symmetrical;

[0063] The two second bevel gears 64 are fixedly connected to one of the drive rollers in the two conveying assemblies through the transmission shaft 63, and the two second bevel gears 64 are symmetrically arranged, so that the rotation of the first bevel gear 62 can drive the two second bevel gears 64 to rotate synchronously and in opposite directions, and then can synchronously drive the two conveyor belts 2 to rotate in opposite directions, forming a loading and unloading movement during the ceramic product inspection process. It has a good linkage and combination function, and does not require an additional electric drive source for driving, thereby improving the energy saving and environmental protection of the equipment.
