[0035] Example 2
[0036] The label detection device in this embodiment is improved based on embodiment 1 as follows: Figure 1 , Figure 5 As shown, a telescopic rod 3 is installed on one outer wall of the base 1. A push plate 4 is fixed to the telescopic end of the telescopic rod 3. A discharge hopper 17 is provided on the side wall of the base 1, opposite to the telescopic rod 3. A guide frame 18 is provided on one side of the base 1. A movable disk 19 is slidably fitted on the inner wall of the guide frame 18.

A pressure sensor is installed on the inner wall of the movable disk 19, and its top contacts and cooperates with the placement plate 21.
[0037] When a problematic label is detected, the telescopic rod 3 pushes the product toward the discharge hopper 17 via the push plate 4. The product falls along the discharge hopper 17 into the collection basket located below the discharge hopper 17. The pressure detected by the pressure sensor increases. When the pressure reaches a certain value, the telescopic rod 20 drives the moving plate 19 to move along the guide frame 18, changing the collection basket located below the discharge hopper 17, thereby realizing the automatic replacement of the collection basket.
[0038] By incorporating a telescopic rod 3, a push plate 4, a discharge hopper 17, a guide frame 18, a moving tray 19, a second telescopic rod 20, and a placement plate 21, problematic labels can be collected individually. Furthermore, by detecting the weight of the products in the collection basket, automatic basket replacement can be achieved.
[0039] Working principle: when detecting, the product is conveyed along the conveying belt 2, and when passing under the detection camera 11, the detection camera 11 takes a picture of the product, which is conveyed to an external device for visual analysis to detect the label, when a problem label is detected, the telescopic rod one 3 pushes the product to the discharge hopper 17 through the push plate 4, and the product falls into the collection basket located below the discharge hopper 17, the pressure sensor detects the increase of pressure, when the pressure reaches a certain value, the telescopic rod two 20 drives the moving disc 19 to move along the guide frame 18, changes the collection basket located below the discharge hopper 17, realizes the automatic replacement of the collection basket; when the detection camera 11 needs to be adjusted, the electromagnet between the rotating cylinder 25 and the connecting frame 26 at one end of the hollow cylinder 23 changes to the same pole, pushes the connecting frame 26 to stretch out through repulsion, and the limiting slot is limited by the limiting spline 27, at this time, the motor can drive one hollow cylinder 23 to rotate through the transmission of the rotating shaft 22 and the rotating cylinder 25, and drive the threaded rod 7 or the rotating shaft 14 to rotate through the bevel gear transmission assembly 24, at this time, the electromagnet between the rotating cylinder 25 and the connecting frame 26 at one end of the other hollow cylinder 23 is different, so that the connecting frame 26 is retracted into the rotating cylinder 25 and does not contact with the limiting spline 27, if the threaded rod 7 is driven to rotate, the fixed frame 8 can be lifted along the threaded rod 7. Change the height of the detection camera 11, if the rotating shaft 14 is driven to rotate, the worm 16 can be driven to rotate. The rotating rod 10 is rotated through the transmission of the worm wheel 15 and the worm 16, and the angle of the detection camera 11 is changed; when the detection camera 11 needs to be repaired, pull down the plug rod 12 to make the plug rod 12 disengage from the through hole, so that the connection between the limiting block 13 and the rotating rod 10 is released, and the detection camera 11 is removed, which is convenient for disassembling and assembling the detection camera 11.
[0040] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the inventive concept of the present application within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
