Description

Technical Field

[0001] This utility model relates to the field of mechanical gripper technology, and in particular to an easy-open lid stacking gripper. Background Technology

[0002] In the production process of easy-open lids, metal materials are first stamped into basic lids using a basic lid punch press. Then, these basic lids are processed by an edge rolling machine to curl the edges, and sealant is injected by a glue injection machine. After drying in a dryer, these lids are further shaped on a combination punch press, and the pull ring is riveted to the lid. Finally, the finished easy-open lids are packaged and stored in long cylindrical paper bags and stacked on pallets for stacking.

[0003] As disclosed in the existing Chinese utility model patent with publication number CN222906951U, "a palletizing and handling gripper for easy-open lids includes: a lid fixing mechanism, including an adsorption mechanism and a constraint mechanism, wherein the adsorption mechanism can be detachably fixed to the easy-open lid assembly, and the constraint mechanism can fix or release the easy-open lid assembly along a first direction; a pallet gripping mechanism, including a first clamping arm and a second clamping arm, wherein the first clamping arm and the second clamping arm are arranged opposite to each other, and the first clamping arm and the second clamping arm can move relative to each other to clamp and fix the pallet, or the first clamping arm and the second clamping arm can move in opposite directions to release the pallet." However, since the easy-open lid assembly is a columnar structure, without radial limiting of the easy-open lid assembly, the device is prone to rolling when gripping the easy-open lid assembly. This makes it difficult for the lid fixing mechanism to accurately adsorb from the top and apply uniform pressure from both ends to firmly clamp the easy-open lid assembly. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-open lid palletizing gripper in order to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A palletizing gripper for easy-open lids includes a top plate and a columnar easy-open lid assembly, and further includes:

This layout allows the limiting rods to effectively restrict the easy-open cover assembly radially from multiple directions, thereby effectively preventing the easy-open cover assembly from rolling during adsorption or transportation. Furthermore, since the limiting rods can directly participate in limiting the position of the easy-open cover assembly, even if the negative pressure adsorption force is insufficient or uneven, the easy-open cover assembly will not easily roll.

Detailed Implementation

[0041] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0042] Please see Figure 1-6 This utility model provides a technical solution: a palletizing gripper for easy-open lids, including a top plate 1 and a columnar easy-open lid assembly 14. A movable plate 3 is vertically slidably arranged below the top plate 1. A hydraulic rod 2 is fixedly installed on the top plate 1, driving the movable plate 3 to move up and down to grip or release the easy-open lid assembly 14. The free end of the hydraulic rod 2 is fixedly connected to the movable plate 3. A first guide rod 4 passes through the top plate 1 and is fixedly connected to the movable plate 3, serving as a guide to ensure the smooth vertical movement of the movable plate 3. An adsorption plate 13 is vertically slidably arranged below the movable plate 3, directly contacting and adsorbing the easy-open lid assembly 14. Limiting rods 10 are fixedly arranged in a rectangular array at the bottom of the movable plate 3. The easy-open lid assembly 14 is arranged between two adjacent rows of limiting rods 10. The free end of the limiting rod 10 passes through the adsorption plate 13, serving as a guide and limiting element. A compression spring is also included. The compression spring 11 is mounted on the limiting rod 10. The two ends of the compression spring 11 are fixedly connected to the movable plate 3 and the adsorption plate 13 respectively, providing buffer elasticity for the adsorption plate 13 to prevent excessive impact during adsorption. The bottom of the adsorption plate 13 is provided with an arc-shaped groove 131 that fits the shape of the easy-open cover assembly 14. The shape fits the outer contour of the easy-open cover assembly 14 to improve adsorption stability. The adsorption plate 13 has several negative pressure cavities 1301 located between adjacent columns of limiting rods 10 to form a vacuum adsorption space. The bottom of the adsorption plate 13 has several adsorption holes 1302 that communicate with the negative pressure cavities 1301 along the axial direction of the easy-open cover assembly 14 to adsorb the easy-open cover assembly 14. One end of the negative pressure tube 12 passes through the top plate 1 and the movable plate 3 and is fixedly connected to the negative pressure cavity 1301. The other end of the negative pressure tube 12 is fixedly connected to the negative pressure machine to provide a source of suction.

[0043] The limiting rods 10 are fixedly arranged in a rectangular array at the bottom of the movable plate 3, and the easy-open lid assembly 14 is arranged between two adjacent rows of limiting rods 10. This layout allows the limiting rods 10 to effectively restrict the easy-open lid assembly 14 radially from multiple directions, thereby effectively preventing the easy-open lid assembly 14 from rolling during adsorption or transportation. Furthermore, since the limiting rods 10 can directly participate in limiting the position of the easy-open lid assembly 14, even if the negative pressure adsorption force is insufficient or uneven, the easy-open lid assembly 14 will not easily roll.

[0044] Specifically, such as Figure 1 , Figure 3 and Figure 6As shown, the clamping plates 7 are slidably arranged on both sides of the movable plate 3, clamping the easy-open cover assembly 14 from the side to enhance the overall gripping stability. The cylinders 5 are fixedly installed on both sides of the movable plate 3 to drive the clamping plates 7 to open and close. The connecting seats 6 are fixedly connected to both sides of the clamping plates 7. The free end of the cylinder 5 is fixedly connected to a set of connecting seats 6. The fixing seat 9 is fixedly connected to both sides of the movable plate 3. The second guide rod 8 is fixedly connected to another set of connecting seats 6 and is linked with the clamping plates 7 to ensure the linear movement of the clamping plates 7 and improve the clamping accuracy. The free end of the second guide rod 8 passes through the fixing seat 9 and serves as the guide fulcrum of the second guide rod 8.

[0045] Working principle: During use, the gripper moves directly above the cylindrical easy-open lid assembly 14 to be gripped. The hydraulic rod 2 is in its initial position, and the movable plate 3 and the adsorption plate 13 are in a high position. The hydraulic rod 2 is activated, pushing the movable plate 3 downward. As the movable plate 3 moves downward, the adsorption plate 13, under the action of the compression spring 11, first contacts the surface of the easy-open lid assembly 14. The negative pressure machine is activated, supplying air to the negative pressure chamber 1301 through the negative pressure pipe 12. The adsorption hole 1302 generates suction, adsorbing the easy-open lid assembly 14 into the arc-shaped groove 131. After adsorption is completed, the cylinder 5 is activated, pushing the clamping plate 7 towards the center. The clamping plate is guided by the second guide rod 8. The easy-open lid assembly 14 is precisely clamped on both sides to further enhance gripping stability and prevent shaking or falling off during transportation. The hydraulic rod 2 moves in the opposite direction, driving the movable plate 3, the adsorption plate 13 and the clamping plate 7 to rise together, lifting the easy-open lid assembly 14 from the conveyor line. At this time, the easy-open lid assembly 14 is doubly fixed by adsorption and clamping, with extremely strong stability, suitable for long-distance transportation or stacking operations. After reaching the target position, the negative pressure machine is turned off first to release the adsorption force. Then, the cylinder 5 drives the clamping plate 7 to open outward, releasing the easy-open lid assembly 14. Finally, the adsorption plate is detached from the easy-open lid assembly 14, completing the action of placing the easy-open lid assembly 14 on the pallet.

[0046] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
