[0024] Example
[0025] An automatic label inspection device, such as Figure 1 As shown, the system includes a lifting mechanism 1, a feeding mechanism 2, a conveyor belt 3, a detection camera 4, a discharging mechanism 5, a qualified product box 6, and an NG product box 7. The lifting mechanism 1 and the front section of the conveyor belt 3 are arranged adjacent to each other, and the feeding mechanism 2 is located above the front section of the lifting mechanism 1 and the conveyor belt 3. The rear section of the conveyor belt 3 and the qualified product box 6 are arranged adjacent to each other, and the discharging mechanism 5 is located above the qualified product box 6 and the rear section of the conveyor belt 3. The NG product box 7 is located below the end of the conveyor belt 3. The detection camera 4, which can detect whether the label is qualified, is located between the feeding mechanism 2 and the discharging mechanism 5 and above the conveyor belt 3.
[0026] like Figure 2As shown, the lifting mechanism 1 includes a label placement station 1-1, a support frame 1-2, an electric lifting rod 1-3, a height sensor 1-4, and an antistatic device 1-5. The label placement station 1-1 is located in the middle of the support frame 1-2, and its bottom is connected to the electric lifting rod 1-3. The label placement station 1-1 can be raised and lowered along the contact area with the support frame 1-2. The height sensor 1-4 and the antistatic device 1-5 are both installed on the support frame 1-2. The height sensor 1-4 can detect the lifting position of the label in the label placement station 1-1, and the antistatic device 1-5 can remove static electricity from the label in the label placement station 1-1.
[0027] like Figure 3 As shown, the feeding mechanism 2 includes a first adsorption device 2-1, a first servo motor 2-2, a first connecting rod 2-3, and a needle cylinder 2-4. The first adsorption device 2-1 is connected to the first servo motor 2-2 via the first connecting rod 2-3. Driven by the first servo motor 2-2, the first adsorption device 2-1 can move up and down and laterally. The bottom of the first adsorption device 2-1 is provided with four first suction cups 2-1-1, arranged in two groups of symmetrically. One group is connected to the needle cylinder 2-4, and driven by the needle cylinder 2-4, this group can move horizontally closer to or away from the other group. This design allows the two groups of first suction cups 2-1-1 to approach each other when adsorbing the label 10, causing the label to bend slightly and separate from the label attached below, preventing label sticking.
[0028] like Figure 4 As shown, the feeding mechanism 2 is located above the lifting mechanism 1. The first suction cup 2-1-1 can pick up the label 10 in the label placement station 1-1. The output end housing of the first servo motor 2-2 is provided with a downward-opening arc-shaped track. The first connecting rod 2-3 is installed on the arc-shaped track. Under the drive of the first servo motor 2-2, the first connecting rod 2-3 can move along the arc-shaped track, that is, simultaneously lift and traverse, moving the first suction cup 2-1-1 onto the conveyor belt 3.
[0029] like Figure 5 As shown, the feeding mechanism 5 includes a second adsorption device 5-1, a second servo motor 5-2, and a second connecting rod 5-3. The second adsorption device 5-1 is connected to the second servo motor 5-2 via the second connecting rod 5-3. Driven by the second servo motor 5-2, the second adsorption device 5-1 can move up and down and laterally. A second suction cup 5-1-1 is provided at the bottom of the second adsorption device 5-1, with two suction cups 5-1-1 symmetrically arranged. The structure of the second servo motor 5-2 and the second connecting rod 5-3 is the same as that of the first servo motor 2-2 and the first connecting rod 2-3 described above. The second suction cup 5-1-1 can pick up the label 10 transported by the conveyor belt 3 and move it into the qualified product box 6 under the drive of the second servo motor 5-2.
[0030] Both the first suction cup 2-1-1 and the second suction cup 5-1-1 can adopt a vacuum suction cup structure, and the surface of the suction cup is covered with an antistatic coating.
[0031] like Figure 6 As shown, a first color sensor 8 and a second color sensor 9 are also provided above the conveyor belt 3. The first color sensor 8 is located near the detection camera 4. After the first color sensor 8 detects that the label 10 is in place, it triggers the detection camera 4 to take a picture. The second color sensor 9 is located near the unloading mechanism 5. After the second color sensor 9 detects the transmitted label and the system determines that the label is a qualified product, it triggers the unloading mechanism 5 to work.
[0032] The working process and principle of the above-mentioned automatic label inspection equipment are as follows:
[0033] The manual staff places approximately 500 stacked labels to be tested into the label placement station 1-1 on the label lifting mechanism 1. The electric lifting rod 1-3 automatically raises the height, and stops when the height sensor 1-4 detects that the label is in position. The static eliminator 1-5 is then activated to remove static electricity from the labels in the label placement station 1-1.
[0034] The feeding mechanism 2 moves above the lifting mechanism 1 and lowers the first adsorption device 2-1. The first suction cup 2-1-1 picks up a label 10. At the same time as it rises, the needle cylinder 2-4 pushes a set of first suction cups 2-1-1 to move horizontally, causing the label 10 to bend slightly, thereby separating it from the label that is tightly attached below and preventing the label from sticking.
[0035] The feeding mechanism 2 transfers the picked-up label 10 to the conveyor belt 3. The conveyor belt 3 transports the label 10 to the inspection camera 4 at a uniform speed. After the first color sensor 8 detects that the label 10 is in place, it triggers an image capture. The label 10 continues to be transported forward. After the second color sensor 9 detects the label 10 and the system determines that the label 10 is a qualified product, it triggers the unloading mechanism 5 to work. The second suction cup 5-1-1 at the bottom of the unloading mechanism 5 picks up the qualified label and moves it into the qualified product box 6. The defective label can flow directly into the NG product box 7, completing the automatic inspection of a label. The label to be inspected can be made of materials such as PET and coated paper.
[0036] The aforementioned automatic label inspection equipment can be set up in several groups in parallel to work simultaneously, thereby improving inspection efficiency.
[0037] In the aforementioned equipment, each mechanism can be mounted on a frame, with a control device installed next to it. The device has a built-in PLC control system to control the start, stop, and operation of each mechanism.
[0038] This utility model provides a general approach, and there are many ways to implement this technical solution. The above description is only a preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model. All components not explicitly stated in this embodiment can be implemented using existing technology.
