By installing the first detection lens 26 on the adjustment component 25, the lens height can be adjusted according to actual requirements, so that the first detection lens 26 can collect and focus images and project the image of the label product to the subsequent image sensor or image processing system. In addition, the selection of the first detection lens 26 should be determined according to the size of the label product, the detection requirements and the configuration of the visual system to ensure that a clear and high-quality image is obtained.

[0047] In a specific embodiment, the first detection component 21 and the second detection component 22 are visual detection components of the same structure, so as to facilitate the replacement, repair and maintenance of the visual detection components and reduce production costs.

Specifically, the flip device 3 is fixed to the side of the conveyor belt 11 through a bearing seat bracket. In this way, the flip motor 31 drives the flip shaft 32 to rotate and provide power, thereby driving the label on the conveyor belt 11 to complete the flip operation, so that the two sides of the label product can be detected in the subsequent processing process.

[0050] In one embodiment, the flip plate 33 includes a plate body 331 and a roller 332 rotatably connected to the plate body 331; the end of the plate body 331 away from the flip shaft 32 is a sharp end. Specifically, the end of the plate body 331 is designed with a sharp tip, and the middle part of the plate body 331 is provided with a roller 332, and the plate body 331 is connected to the flip shaft 32 through a fastener. In this way, when the conveyor belt 11 conveys the label product to the flip plate 33, the sharp end of the plate body 331 guides the label product to be pushed onto the plate surface of the plate body 331 by the conveyor belt 11, and the rolling of the roller 332 is used to avoid excessive friction between the label product and the plate surface and difficulty in moving, so as to ensure that the label product to be reversed can be smoothly moved to the plate body 331.

In this way, the first moving component 42 drives the second moving component 43 and the suction cup 44 to move horizontally, and the second moving component 43 drives the suction cup 44 to move vertically, so that the label product adsorbed by the suction cup 44 can move up, down, left, and right.

[0052] In a specific embodiment, the sorting device 4 further includes a waste box, and the suction cup member 44 absorbs defective label products and removes them into the waste box.

[0053] In one embodiment, the first movable component 42 includes a first cylinder 421 fixedly mounted on the gantry bracket 41, and a first movable seat 422 driven by the first cylinder 421; the second movable component 43 includes a second cylinder 431 fixedly mounted on the first movable seat 422, and a second movable seat 432 driven by the second cylinder 431, and the suction cup member 44 is fixedly mounted on the second movable seat 432.

[0054] In one embodiment, the first movable component 42 also includes a first guide unit 45, and the second movable component 43 also includes a second guide unit 46; the first guide unit 45 includes a guide rail member 451 arranged on the gantry bracket 41, and a guide rail seat 452 arranged on the first movable seat 422, and the guide rail seat 452 is adapted to the guide rail member 451; the second guide unit 46 includes a guide cylinder 461 arranged on the first movable seat 422, and a guide rod 462 arranged on the second movable seat 432, and the guide rod 462 is adapted to the guide cylinder 461.

[0055] In one embodiment, the first cylinder 421 is a rodless cylinder. Compared with ordinary cylinders, the rodless cylinder has the following characteristics: the installation device can be reduced under the same stroke, and no anti-rotation mechanism is required; the stroke range is large and the moving speed is stable and reliable.

[0056] In one embodiment, the first light source 24 is a ring light source, a strip light source or a rectangular light source. In this way, different light source shapes are selected according to different environmental requirements to ensure that the detected label product has sufficient brightness and contrast during shooting or image acquisition.

[0057] The working principle of this flip detection and sorting system is as follows Figure 8 As shown, the label product is conveyed by the conveyor belt 11 of the conveying device 1, and the first detection component 21 is used to perform defect detection on the first side of the label product. Then the conveyor belt 11 conveys the label product to the flipping device 3, the flipping device 3 flips the label product, and the conveyor belt 11 continues to convey the label product. The second detection component 22 performs defect detection on the second side of the label product, the conveyor belt 11 continues to convey the label product, and the sorting device 4 removes the label product with label defects on the first side or the second side from the conveyor belt 11.

[0058] In one embodiment, the flip detection and sorting system includes the following working steps:

[0059] Step 1: The conveyor belt 11 transmits the label image to be inspected to the first inspection component 21. According to the image quality, the illumination intensity of the first light source 24 is adaptively adjusted, and the relative position of the adjustment component 25 and the first inspection lens 26 is adjusted to adjust the shooting height. At the same time, the image information of the front of the label product is collected for defect detection to realize the defect detection of the front of the label. If defect information is identified, it is uploaded to the host computer system and saved in the database.

[0060] Step 2: The conveyor belt 11 transmits the label to the infrared sensor in front of the flipping device 3 to trigger the flipping device 3. When the label is transmitted to the label flipping device 3, the sharp end in front will lift the label product and transport it to the plate surface through the roller 332 on the plate body 331. Then the flipping motor 31 drives the flipping shaft 32 and the flipping plate 33 to rotate backward at a certain angle through the key connection to complete the flipping operation and realize the flipping of the label product. Then the flipping motor 31 reverses to reset the flipping shaft 32 and the flipping plate 33.

[0061] Step 3: Similar to step 1, the conveyor belt 11 conveys the flipped label product to the second detection component 22 to detect the image information on the back of the label product to achieve defect detection on the back of the label product. If defect information is identified, it is uploaded to the host computer system and saved in the database.

[0062] Step 4: If both the front and back sides of the label are inspected correctly, the label product will be transported to the finished product warehouse along the conveyor belt 11. If one of the first inspection component 21 and the second inspection component 22 identifies a defect, the sorting device 4 starts the first moving component 42 to move the second moving component 43 and the suction cup 44 to the top of the conveyor belt 11, and then the second cylinder 431 starts to release pressure, and moves the suction cup 44 down to the surface of the label product to be removed, and at the same time starts the suction cup 44 to absorb the label product. Then the first moving component 42 and the second moving component 43 are reset, and the suction cup 44 is moved to the top of the waste box. At this time, the suction cup 44 is closed, and the defective label product is placed in the waste box to realize the sorting operation of the label waste.

[0063] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
