Description

Technical field

[0001] The utility model mainly relates to a double-sided vacuum picking palm of an industrial robot. [Background Technology]

[0002] With the continuous development of science and technology, the manual assembly line operations originally used in production and processing operations have gradually been replaced by fully mechanized automated production lines, thereby effectively saving labor costs. In particular, in standardized industrial production environments, high-tech industrial robot equipment has been used as processing nodes on the production line to replace manual operations. The advantages of industrial robots such as high stability, large load-bearing capacity and precise operation are used to carry out modern production and processing, which has gradually become popular in various large-scale fully mechanized automated production lines.

[0003] Existing industrial robots are generally equipped with traditional single-suction cup grippers to grasp workpieces. However, this single-suction cup gripper has few suction points and is prone to falling off. It also generally grasps parts on one side, so the number of workpieces grasped at a time is small, resulting in low production efficiency. In view of this, in order to improve production efficiency, we propose a new structural solution. [Utility Model Content]

[0004] In order to solve at least one of the above problems, the present invention proposes a new structural solution. The present industrial robot double-sided vacuum pickup palm adopts the following technical solutions:

[0006] The gas transmission plate is mounted at the end of the support arm, and the gas transmission plate and the support arm are detachably assembled. The gas transmission plate includes a first end face and a second end face, and the first end face and the second end face are respectively located on both sides of the gas transmission plate. The gas transmission plate is a hollow structure as a whole, and a plurality of gas outlets extend from the first end face and the second end face. The gas outlets and the gas nozzles are detachably assembled, and the gas nozzles are connected to the gas outlets so that the air flow in the gas transmission plate flows through the gas outlets to the gas nozzles.

[0007] The air nozzle and the air outlet are both provided with semicircular blocks, and the air flow is controlled by pairing the semicircular blocks of the air nozzle and the air outlet.

[0008] Preferably, an extension plate is installed at the head end of the support arm, a docking plate is provided at the end, and the gas transmission plate is installed on the extension plate.

[0009] Preferably, reinforcing ribs are provided between the extension plate and the support arm, and between the docking plate and the support arm.

[0013] Compared with the background technology, the utility model has the following beneficial effects:

[0014] To improve production efficiency, this utility model proposes a double-sided vacuum gripper for industrial robots. It utilizes an air supply plate connected to an air pump to provide air flow. The air supply plate is connected to the air nozzle via an air outlet. To accommodate different workpieces, the air outlet and air nozzle utilize a detachable assembly structure, allowing for replacement of the air nozzles. Furthermore, the air supply plate and support arm utilize a detachable assembly structure, allowing the air supply plate to be resized to meet specific needs. This gripper features air nozzles on both sides, enabling simultaneous suction of workpieces from both sides. This reduces the number of robot movements, speeds up the retrieval process, and improves overall production efficiency. Multiple air nozzles on a single side provide a greater contact area and greater suction force, facilitating stable grasping and handling of irregularly shaped or lightweight, slippery workpieces, reducing the risk of slippage during handling. Vacuum suction reduces safety incidents caused by improper gripping, providing a safer and more reliable method for retrieval, particularly in high-speed automated production. The gripper boasts a simple structure, compact fit, and rational design, resulting in a product with superior technical and economic performance.

[0025] The gas transmission plate 2 is mounted on the end of the support arm 1. The gas transmission plate 2 and the support arm 1 are assembled in a detachable manner. The gas transmission plate 2 includes a first end surface 21 and a second end surface 22, which are respectively located on either side of the gas transmission plate 2. The gas transmission plate 2 is a hollow structure as a whole. A plurality of gas outlets 23 extend from the first end surface 21 and the second end surface 22. The gas outlets 23 and the gas nozzles 3 are assembled in a detachable manner. The gas nozzles 3 are connected to the gas outlets 23 so that the air flow in the gas transmission plate 2 flows through the gas outlets 23 to the gas nozzles 3.

[0026] Both the air nozzle 3 and the air outlet 23 are equipped with semicircular blocks 24. The semicircular blocks 24 of the air nozzle 3 and the air outlet 23 are paired to control airflow. When the semicircular blocks 24 of the two overlap, the air nozzle and the air outlet are connected to allow air to flow. When the semicircular blocks 24 of the two are staggered to form a full circle, the two semicircular blocks 24 can be used to block the flow of air. The air nozzle can be rotated to control the flow of gas and can be opened and closed as needed. The air outlet 23 is equipped with a first annular groove 25, and the air nozzle 3 is equipped with a second annular groove 31. The second annular groove 31 is sleeved with a sealing ring 32. The air nozzle 3 is connected to the air outlet 23 so that the sealing ring 32 is embedded in the first annular groove 25 to prevent the air nozzle 3 from escaping from the air outlet 23. The second annular groove 31 is surrounded by a protrusion 33. The inner side of the sealing ring 32 is equipped with an interface 34. The protrusion 33 is connected to the interface 34 to prevent the sealing ring 32 from escaping from the second annular groove 31.

The gas supply plate 2 is mounted on the extension plate 4. The end of the support arm 1 is equipped with a docking plate 5. The cross-sectional area of the docking plate 5 and the extension plate 4 are both larger than that of the support arm 1. The support arm 1 is locked to the industrial robot via the docking plate 5. The industrial robot preferably uses existing industrial robot arm products. Reinforcing ribs 51 are installed between the extension plate 4 and the support arm 1, and between the docking plate 5 and the support arm 1 to enhance overall strength.

Screws simultaneously lock the flange 22 and the extension plate 4 to secure the gas supply plate 2 to the support arm 1. An air pipe is connected to the end of the rod 21 to supply air to the gas supply plate 2.

[0028] To improve production efficiency, this utility model proposes a double-sided vacuum gripper for industrial robots. It utilizes an air supply plate 2 connected to an air pump to provide air flow. The air supply plate 2 is connected to the air nozzle 3 via an air outlet 23. To accommodate different workpieces, the air outlet 23 and air nozzle 3 are assembled in a detachable structure, allowing the air nozzle 3 to be replaced according to the workpiece. Furthermore, the air supply plate 2 and the support arm 1 are assembled in a detachable structure, allowing the air supply plate 2 to be resized to meet specific needs. This gripper is equipped with air nozzles 3 on both sides, allowing it to simultaneously grip workpieces from both sides. This reduces the number of robot movements, speeds up the retrieval process, and improves overall production efficiency. Furthermore, multiple air nozzles 3 on a single side provide greater contact area and greater suction force, facilitating stable grasping and handling of irregularly shaped or lightweight, slippery workpieces, reducing the risk of slippage during handling. Vacuum suction can reduce safety incidents caused by improper gripping, providing a safer and more reliable method for retrieval, particularly in high-speed automated production.
