The first clamping arm 3033 and the main body of the clamping cylinder 3031 are fixed by the first clamping connection block 3032, and the first clamping arm 3033 is in an L row, including the fixed end of the first clamping arm 3033 and the first clamping arm 3033 Clamping end, the fixed end of the first clamping arm 3033 is fixed on the first clamping connection block 3032, and the clamping end of the first clamping arm 3033 is perpendicular to the first clamping connection block 3032; the second The clamping arm 3035 and the second slider are fixed by the second clamping connection block 3034, and the second clamping arm 3035 is perpendicular to the second clamping connection block 3034 and clamped with the first clamping arm 3033 The holding ends are on the same vertical plane. The propelling cylinder 301 and the clamping cylinder 3031 are distributed on both sides of the propelling rail 302, wherein the first clamping arm 3033 and the second clamping arm 3035 are formed perpendicular to the propelling cylinder 301 and the clamping cylinder 3031 plane.

There is a certain gap between the first clamping arm 3033 and the second clamping arm 3035 , and the gap can be adjusted by expanding and contracting the clamping cylinder 3031 . Specifically, when the propelling cylinder 301 is fixed, since the second clamping arm 3035 is fixed on the second slider, and the second clamping arm 3035 and the clamping cylinder 3031 telescopic rod and the propelling cylinder 301 telescopic rods are fixedly connected, so the positions of the second push slider and the second clamping arm 3035 remain unchanged. At this time, if the clamping cylinder 3031 telescopic rod of the clamping cylinder 3031 stretches out, because the first clamping arm 3033 is fixed on On the first slider, and fixedly connected with the clamping cylinder 3031 body, it will push the first clamping arm 3033 and the first pushing slider upwards, so that the first clamping arm 3033 and the second clamping arm 3035 The gap between them widens.

The peeling mechanism 3 also includes a waste removal device and a waste box 308 for collecting the release paper 502, the waste box 308 is located at a position below the stripping station, and can surround the surroundings of the clamping device 303, the The waste removal device is used to push the stripped release paper 502 into the waste box 308 . The waste removal device is located above the lower limit position of the clamping mechanism. The waste removal device includes a waste removal cylinder 306 and a waste removal push block 307. The waste removal push block 307 covers a part of the peeled release paper 502.

The operating principle of stripping mechanism 3 is:

Under the initial conditions, the clamping device 303 is located between the initial bearing plate 304 and the receiving plate 305, more specifically, the first clamping arm 3033 and the second clamping arm 3035 of the clamping device 303 are located between the initial bearing plate 304 and the receiving plate 305, now the clamping cylinder 3031 telescopic rod of the clamping cylinder 3031 is in the state of stretching out, and the gap between the first clamping arm 3033 and the second clamping arm 3035 is large enough to make the release of the label 5 to be separated The paper 502 passes through the middle, and the suction cup 206 is carrying the label 5 to be separated. The label 5 to be separated passes above the primary bearing plate 304 and just extends into the gap between the first clamping arm 3033 and the second clamping arm 3035. The label 5 to be separated includes a sheet label 501 and a release paper 502 that are adhered to each other, wherein the area of the release paper 502 is greater than the area of the sheet label 501, and the edge of the release paper 502 protrudes from the edge of the sheet label 501, Therefore, in the process of preliminary debugging, the stop position of the suction cup 206 allows the release paper 502 of the label 5 to be separated to stretch into the gap between the first clamping arm 3033 and the second clamping arm 3035, while the sheet label 501 does not stretch out. enter. The suction cup 206 stops vacuuming, and when the separated label 5 falls onto the initial support plate 304, the clamping cylinder 3031 retracts, the first clamping arm 3033 and the second clamping arm 3035 clamp the release paper 502, and the pushing cylinder 301 stretches out, pushing The clamping device 303 descends. At this time, the first clamping arm 3033 and the second clamping arm 3035 clamp the release paper 502, so that the release paper 502 is peeled off from the sheet label 501, because in the process of peeling, under the condition of inertia, the release paper 502 A forward force is provided for the sheet label 501 , so when the release paper 502 is peeled off from the sheet label 501 , the sheet label 501 is driven forward into the receiving groove of the receiving plate 305 . When the release paper 502 is about to be completely peeled off, the release paper 502 is parallel to the push cylinder 301 and the push guide rail 302 and is in a state of approximately tension, the waste removal cylinder 306 stretches out, and the waste removal push block 307 pushes away The mold paper 502 falls off completely, the clamping cylinder 3031 stretches out, the first clamp arm 3033 and the second clamp arm 3035 are opened, and the release paper 502 falls into the waste box 308 .

In order to ensure the peeling effect, preferably, the positions of the first clamping arm 3033 and the second clamping arm 3035 are extremely close to the edge of the receiving plate 305 but they will not interfere during the process of rising and falling. When peeling off the release paper 502, you can Let the sheet label 501 be quickly pushed into the receiving groove, because the receiving plate 305 provides the receiving force, and the inside of the receiving groove is in a jagged shape, which reduces the contact area, prevents the sheet label 501 from transitionally sticking to the receiving groove, and ensures that the sheet label 501 Can continue to advance. Furthermore, the lower surface of the suction cup 206 is extremely close to the upper surface of the initial bearing plate 304, that is, the gap between the lower surface of the suction cup 206 and the upper surface of the initial bearing plate 304 is slightly larger than the thickness of a label 5 to be separated. When the release paper 502 is peeled off, due to the existence of the suction cup 206, a downward limiting force can be provided slightly to prevent the label 5 to be separated from lifting due to the peeling of the release paper 502, resulting in failure to enter the receiving plate 305 smoothly. Affect the peeling effect; at the same time, because the width of the receiving groove is slightly wider than the width of the sheet label 501, and the length is slightly longer than the length of the sheet label 501, the sheet label 501 itself has a certain viscosity, so when the sheet label 501 gradually enters the receiving groove At this time, the receiving groove itself will play a certain restrictive role to prevent the sheet label 501 from lifting or popping up.

The four-axis robotic arm removes the sheet label 501 from the receiving slot of the label tearing device, and then transports it to the top of the detection device 7. The detection camera detects whether the position of the sheet label 501 is in place. If the detection position is qualified, it is transported to the top of the product. Carry out labeling. If the detection is unqualified, position compensation will be performed according to the image taken by the detection camera. The end of the four-axis mechanical arm will adjust the position of the sheet label 501 until the detection is passed, and then the sheet label 501 will be transported to the top of the product. The shape label 501 is attached to the upper surface of the product.

At this time, because the four-axis mechanical arm only puts the sheet label 501 on the upper surface of the product, the degree of adhesion is the lowest, and it is easy to fall off. Therefore, a pressing device 8 is provided above the carrying device 9 for pressing the label. Labels on the top surface of the product.

The pressing roller 805 is higher than the upper surface of the product on the conveying device 9. When the pressing cylinder 804 pushes the fixed frame 806 down, the height of the pressing roller 805 is higher than the upper surface of the product and slightly lower than the sheet. The upper surface of the label 501, so the pressing roller 805 can exert a greater pressure on the label 501 during the return process of the product, so that the label 501 is tightly attached to the upper surface of the product.
