Description

Technical Field

[0001] The utility model relates to the technical field of alternating detection, in particular to an alternating detection mechanism. Background Art

[0002] When it is necessary to perform appearance detection on products, multiple products are placed on a rack. Then, an imaging mechanism performs appearance detection on the products on the rack one by one. After the detection of multiple products is completed, after a stopping device, the tray containing multiple products is moved. Then, multiple products that have not been detected well are placed on the rack. During this process, it is necessary to stop the detection device for a period of time, resulting in too low work efficiency for detecting products.

[0003] The existing alternating detection mechanism can refer to the Chinese utility model patent with the authorization announcement number CN213658598U, which discloses an appearance detection device, "including a rack, support feet, a conveyor belt, vertical plates, a first lead screw, a first stepping motor, a moving block, a connecting plate, a second stepping motor, a second lead screw, a mounting frame, a detection camera, a lighting lamp, a fixing frame, an electric slide rail, a slider, a clamping cylinder, a piston rod, a sleeve, a buffer spring, a push plate, a push rod, a clamping plate, a slide rod, a protection pad, a fastening frame and a rotating motor. Support feet are welded at the four corners of the bottom of the rack. A conveyor belt is installed on the rack through conveyor wheels.

The utility model has good detection effect, good fixing effect on products, and is convenient for detecting different surfaces of products."
