The suction cup portable bracket is also called the suction cup manipulator, which is used to grab objects. The shapes of manipulators are various, including suction cup type, grab type, electromagnetic type, hook type and so on. Among them, the vacuum suction cup type is widely used in various fields because of its structure, simple control, and cleanliness. Suction cup manipulators are good at grabbing items with flat and regular surfaces, so they are used in logistics, production sorting, food industry, automobile production, glass handling, sheet metal parts handling and other fields. The number and types of them are the largest among grabbing manipulators.
Let's classify according to the purpose, and look at the application scenarios of the suction cup manipulator
1. Item grabbing
It is mostly used for lifting and transferring heavy objects. Such as carton palletizing and parcel grabbing in the logistics industry; such as lifting and grabbing of parts and products in the mechanical and chemical industry; grabbing and flipping of glass and sheet metal parts, such as airport luggage transfer and handling; such as lifting and transferring of large parts.
These mechanical arms have a simple structure, most of them are flexible arms with suction cups, and they are operated by humans to reach designated objects, and there is almost no control system. The price is cheap and the application is widely distributed. It is mainly to replace manual handling and lift heavy objects. A slightly more complicated machine with less degrees of freedom can realize the flipping of the grasped items.
2. Automatic palletizing
It is mostly used in logistics, warehousing, and ports. It is used for automatic grabbing of materials and fixed-point stacking functions, such as sorting and palletizing in the logistics industry and production enterprises;
This type of robot has a robotic arm that can move automatically, but most of them have low degrees of freedom and realize relatively simple movements. The requirements for positioning accuracy are not high, the program and control system are relatively simple, and the actuator is not a precision device.
3. Precise grasping and distribution
In some fields, manipulators are required to accurately grasp and place objects at fixed points, such as food, medical, and electronics industries. These industries have high requirements for cleanliness, and suction cup manipulators are widely used. In order to achieve precise positioning, multi-degree-of-freedom robotic arms are often used. The degrees of freedom and the structure of the robotic arm are also diverse.
Such as food industry, sorting, such as Festo's parallel robot, can be used in electronics industry, food industry, parts. This type of robotic arm is relatively complex, can realize multiple free movements, precise control, accurate positioning, high technical content, and relatively considerable profits.
The operating element of the suction cup manipulator is a vacuum suction cup, which can grab a wide range of objects. Vacuum suction cups have strong suction, clean and hygienic, and are favored by some industries that require cleanliness. The robotic arm can be equipped with various forms and structures. It can be an uncontrolled human-driven flexible arm, a series manipulator with a low degree of freedom, or a parallel manipulator with a high degree of freedom. Matching is more flexible. Based on the advantages of the suction cup manipulator, this type of manipulator accounts for a very large proportion in the manipulator market.
