[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides an embodiment of a multifunctional clamp: such as Figure 1 As shown, the device includes a frame 1, with a connecting plate 8 on the upper part of the frame 1 for connection with palletizing equipment. Both sides of the frame 1 are provided with a plate gripping mechanism 2. The plate gripping mechanism 2 includes a gripping rod 201 and a suction cup 202. The gripping rod 201 is installed on the frame 1, and the suction cup 202 is installed at the end of the gripping rod 201. There are two gripping rods 201 and two suction cups 202 on each side. The two gripping rods 201 are arranged side by side, and the two suction cups 202 are respectively installed at the ends of the two gripping rods 201. Each suction cup 202 is connected to a vacuum generating device. The four gripping rods 201 on both sides are staggered.

[0028] The clamp is mounted on the palletizing equipment via the connecting plate 8 on the frame 1, and the initial state of the clamp is as follows: Figure 1As shown, when the stacking operation of the stacked products 9 needs to be carried out, first, the board grabbing mechanism 2 is used to lay a layer of the separator at the stacking position, at this time, the stacking equipment control frame 1 and the board grabbing mechanism 2 are moved to the separator storage place, and each suction cup 202 is abutted against the upper surface of the separator, then the vacuum generating equipment is used to draw the inside of the suction cup 202 to a negative pressure state, so that the separator can be sucked on the clamp by the suction cup 202, then the stacking equipment can move the separator to the stacking position by the board grabbing mechanism 2, at this time, the vacuum generating equipment is released, and the negative pressure state in the inside of the suction cup 202 is released, so that the separator can be placed at the stacking position, and the purpose of automatic laying of the separator is achieved.

[0029] As shown in Figure 1 , the adjusting assembly 7 is arranged between the grabbing rod 201 and the suction cup 202, the adjusting assembly 7 comprises a nut 701 and an adjusting bolt 702, the nut 701 is fixedly connected to the grabbing rod 201, the adjusting bolt 702 is threadedly connected to the nut 701, and the adjusting bolt 702 is connected to the suction cup 202.

[0030] By screwing the adjusting bolt 702 on the nut 701, the height of the adjusting bolt 702 can be adjusted, so that the height of the suction cup 202 is adjusted, and the height of the suction cup 202 on the clamp can be adjusted according to the use requirements of the operator, thereby improving the flexibility and practicality of the clamp.

[0031] As shown in Figure 1 and Figure 2 , the turnover mechanism 3 is connected between the board grabbing mechanism 2 and the frame 1 on both sides, and the product grabbing mechanism is arranged at the lower part of the frame 1, the product grabbing mechanism comprises a limiting assembly 4 and a supporting assembly 5 arranged side by side, the turnover mechanism 3 comprises a first air cylinder 301, a turnover shaft 302 and a pull plate 303, the turnover shaft 302 is rotationally connected to the connecting plate 8 about its axis and is connected to the grabbing rod 201, the pull plate 303 is fixedly connected to the turnover shaft 302, and the first air cylinder 301 is connected between the pull plate 303 and the frame 1, specifically, the extension end of the first air cylinder 301 is rotationally connected to the pull plate 303 through a pivot, and the other end of the first air cylinder 301 is connected to the frame 1 through a pivot.

[0032] After the separator is moved to the stacking position, the extension end of the first air cylinder 301 is retracted, at this time, the first air cylinder 301 can drive the turnover shaft 302 to rotate about its axis through the pull plate 303, the turnover shaft 302 drives the grabbing rod 201 connected thereto to rotate upward synchronously, and the grabbing rod 201 is folded upward, and the folded state is as shown in Figure 4 and Figure 5 , at this time, the product grabbing mechanism is exposed, and then the grabbing and stacking of the stacked products 9 can be carried out.

[0033] As shown in Figures 1 to 3as well as Figure 5 As shown, the support assembly 5 includes a support frame 501 and a support plate 502. The support frame 501 is connected to the linear sliding assembly 6, and the support plate 502 is horizontally arranged and fixedly connected to the lower part of the support frame 501.

[0034] The limiting component 4 includes a limiting frame 401 and a limiting plate 402. The limiting frame 401 is fixedly connected to the lower part of the frame 1 near the support plate 502, and the limiting plate 402 is installed on the limiting frame 401 on the side away from the support frame 501.

[0035] like Figure 3 As shown, the frame 1 is provided with a linear sliding component 6 connected to the support component 5. The linear sliding component 6 includes a second cylinder 601 and a guide rail 602, both of which are horizontally arranged. The second cylinder 601 and the guide rail 602 are both provided on the frame 1, and the telescopic end of the second cylinder 601 is connected to the support frame 501. A slider 603 is fixed on the upper part of the support frame 501, and the slider 603 is slidably connected to the guide rail 602.

[0036] When stacking product 9, the state of the fixture is as follows: Figure 5 As shown, at this time, the stacking equipment will move the clamp to the storage area of ​​the stacked product 9, and make the limiting frame 401 approach or contact one side of the stacked product 9, while making the limiting plate 402 approach the upper surface of the stacked product 9. Then, control the extension end of the second cylinder 601 to retract. During this process, controlling the extension end of the second cylinder 601 can pull the support frame 501 and the slider 603 to slide along the guide rail 602, thereby driving the support plate 502 to slide towards the limiting frame 401, and lifting the stacked product 9 through the support plate 502. At this time, the limiting plate 402 abuts against the upper surface of the stacked product 9. Therefore, the limiting plate 402 and the support frame 501 cooperate to clamp the stacked product 9 to a certain extent, as shown in the figure. Figure 6 As shown, the palletizing equipment then uses the support plate 502 to transfer the stacked product 9 to the partition that was previously placed at that position. During this process, the limiting plate 402 and the support frame 501 clamp the product 9 to prevent it from falling, thereby ensuring that the product 9 is not damaged by falling during the transfer process.

[0037] After the stacked product 9 is transferred to the stacking area, the telescopic end of the second cylinder 601 is extended outward to push the support frame 501, the slider 603 and the support plate 502 back to their original positions. During this process, the support plate 502 is pulled away from the bottom of the stacked product 9. Moreover, due to the blocking effect of the limit frame 401, the stacked product 9 is prevented from moving with the support plate 502, thereby ensuring that the stacked product 9 can be placed in the designated position on the partition.

[0038] After other products 9 to be stacked are placed on the partition plate in turn in this way, the extension end of the first cylinder 301 is controlled to extend to the original position, in the process, the extension end of the first cylinder 301 can push the turnover shaft 302 to rotate and reset through the pull plate 303, and the grabbing rod 201 and the suction cup 202 are restored to the original position, then another partition plate is grabbed and laid on the upper part of the products 9 to be stacked, then the grabbing rod 201 and the suction cup 202 are folded, and other products 9 to be stacked can be continued to be stacked upward through the limiting assembly 4 and the supporting assembly 5.

[0039] As can be seen, the clamp can not only grab and stack block-shaped products such as the products 9 to be stacked, but also grab and stack plate-shaped products, and therefore can achieve the purpose of cross-stacking block-shaped products and plate-shaped products, so that the clamp has multiple functions and has a positive effect on improving the stacking work efficiency.

[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 person skilled 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.
