[0024] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0025] like Figure 1 As shown, a plastic parts labeling device with label detection function includes a workbench 1, an electrical control box 13, and a conveyor belt 11 mounted on the workbench 1. The conveyor belt 11 is used to transport plastic parts. The device is characterized by further including a label feeding wheel 3, a film roll recovery wheel 2, a labeling component, and a label detection component. The labeling component includes a guide rail 4, a slider 14, a suction cup lifting mechanism 9, a cylinder 8, and a suction cup 10. The guide rail 4 is arranged horizontally, and the slider 14 is mounted on the guide rail 4. The slider 14 is driven by a driving component to reciprocate along the guide rail 4. The slider 14 is connected to the suction cup lifting mechanism 9. The suction cup lifting mechanism 9 lowers... The suction cup 10 is connected to the label feeding wheel 3, and the bottom film of the label feeding wheel 3 is wound around the film recovery wheel 2. The film recovery wheel 2 is located below the guide rail 4. The label detection component includes a first detection camera 5 and a second detection camera 6, which are arranged side by side. The first detection camera 5 is located above the guide rail 4 and is used to acquire label images. The second detection camera 6 is located above the conveyor belt 11 and is used to acquire position images of plastic parts.

[0026] A plastic part labeling device with label detection function mainly includes a label feeding roller 3, a film roll recovery roller 2, a labeling component, and a label detection component. The plastic part is transported to a position below a second detection camera 6 via a conveyor belt 11. The second detection camera 6 acquires a positional image of the plastic part. A first detection camera 5, located above a guide rail 4, is used to acquire label images and determine whether the label is defective based on the acquired image. The suction cup of the labeling component picks up the label from the label feeding roller, and based on the positional image of the plastic part, a slider is activated to move the suction cup along the guide rail to the corresponding position above the plastic part. The suction cup lifting mechanism 9 is then activated to lower the suction cup and attach the label to the corresponding position on the product. The labeled plastic part is then conveyed to a receiving box for collection.

The position of the conveyor belt 11 is adjusted by raising or lowering the workpiece lifting mechanism 12 to suit different types of plastic parts.

[0028] like Figure 3 As shown, the driving component includes a motor 22, a driving wheel 24, a driven wheel, and a transmission belt 23. The motor is connected to the driving wheel 24, and the transmission belt is mounted on both the driving wheel 24 and the driven wheel. The motor drives the driving wheel to rotate, which in turn drives the driven wheel to reciprocate along the guide rail via the transmission belt. The slider is connected to the driven wheel, enabling the slider 14 to reciprocate along the guide rail 4 via the driving component.

[0029] like Figure 1 As shown, the suction cup lifting mechanism 9 includes an electric lifting rod. The electrical control box 13 includes a PLC controller, which electrically controls the label feeding wheel 3, the film roll recovery wheel 2, the labeling component, and the label detection component. Specifically, the label feeding wheel 3 and the film roll recovery wheel 2 are respectively connected to the feeding wheel motor and the film roll motor, and the signal output terminals of the PLC controller are respectively connected to the feeding wheel motor and the film roll motor to realize automatic label feeding. The signal output terminals of the PLC controller are respectively connected to the suction cup lifting mechanism 9, the cylinder 8, and the motor of the drive component; the first detection camera 5 and the second detection camera 6 are connected to the signal input terminals of the PLC controller.
