What Are the Types of Industrial Robots?

 The industrial robots are firstly used in the car manufacturing industry, but now the application of industrial robots is not limited to a certain field. There are the presences of industrial robots in all aspects of modern industry. Today, let’s look at the different types of industrial robots.

If the industrial robots are classified according to their structure, they can be divided into multi-axis robots, SCARA robots, coordinate robots, tandem and parallel robots. As the industrial robots are widely used in the different fields in the industrial area, we can also divide it by the practical applications. There are mainly seven types:

 

1. Palletizing Robot

Palletizing robot is a type of industrial robot engaged in palletizing. Palletizing robot is an industrial robot engaged in palletizing. It puts the objects that have been loaded into containers on pallets and pallets (wood, plastic) in a certain arrangement, and performs automatic stacking. It can stack multiple layers and make it convenient for the forklift to move the layers to the warehouse for storage. Palletizing robots can be integrated into any production line to provide intelligence, robotics, and networking for the production site. It can realize robotic palletizing logistics for a variety of operations in the beer, beverage and food industries. It is widely used in cartons, plastic boxes, bottles, bags, barrels, film packaging products and filling products. It is matched with a three-in-one filling line, etc., to palletize various bottles, cans and bags. The automatic operation of the palletizer is divided into the steps of automatic loading, turning, sorting, stacking, shifting, lifting, loading, unloading and more procedures.

 

2. Welding Robot

Welding robots are one of the most commonly used industrial robots in the daily life. In order to meet the requirements of different applications in various fields, the mechanical interface of the last axis of the robot is usually connects a flange which can be connected to different tools or end effectors. By attaching welding tongs or welding guns to the final shaft flange of industrial robot, it enables the robot can perform automatic welding, cutting or thermal spraying processes.

The welding robots are mainly composed of three major parts and six subsystems. The three major parts are the mechanical part, the sensing part and the control part, and the six subsystems can be divided into mechanical structure system, drive system, perception system, robot-environment interaction system, human-computer interaction system and control system. Welding robots have been widely used in the automobile manufacturing industry, welding automobile chassis, seat frames, guide rails, mufflers, and torque converters, especially in the welding production of automobile chassis.

 

3. Assembly Robot

The assembly robot is used for robotic assembly process. The assembly robot is the important equipment of the flexible automated assembly system, which consists of a robot manipulator, a controller, an end effector and a sensor system. Commonly used assembly robots mainly include programmable universal assembly manipulators, PUMA robots (first appeared in 1978, the ancestor of industrial robots) and planar double-joint robots, SCARA robots. Compared with general industrial robots, assembly robots have the characteristics of high precision, good flexibility, small working range, and can be used with other systems. They are mainly used in the manufacturing industry of various electrical appliances.

 

4. Spraying Robot

Spraying robots, also called paint spraying robots, are industrial robots that can automatically spray paint or spray other paints. The painting robot is mainly composed of a robot body, a computer and a corresponding control system. The hydraulically driven painting robot also includes a hydraulic oil source, such as an oil pump, an oil tank, and a motor. 5 or 6-degree-of-freedom articulated structures are mostly used. The arm has a large space for movement and can do complex trajectory movements. The wrist generally has 2 to 3 degrees of freedom and can move flexibly. The wrist of the more advanced paint spraying robot adopts a flexible wrist, which can bend in all directions and rotate. Its action is similar to a human wrist, and it can be easily extended into the workpiece through a small hole to spray its inner surface. Painting robots are widely used in craft production departments such as automobiles, instruments, electrical appliances, and enamel.

 

5. Handling Robot

Handling robots are industrial robots that can carry out automated technology transportation work. The handling robot can be installed with different electric actuators at the end to carry out various different appearances and conditions of steel transportation work, which greatly relieves people's complicated physical work. Its advantage is that it can perform various estimated daily tasks according to the programming, and has the advantages of human and equipment in its structure and performance, especially in reflecting the artificial intelligence technology and adaptability.

 

6. Laser Processing Robot

Laser processing robots apply robotic technology to laser processing, and realize more flexible laser processing operations through high-precision industrial robots. The system is operated online through the teaching box, and can also be programmed offline. The system generates the model of the processed part through automatic detection of the processed workpiece, and then generates the processing curve. It can also be processed directly by using CAD data. It can be used for laser surface treatment, drilling, welding and mold repair of workpieces.

 

7. Vacuum Robot

A vacuum robot is a kind of robot that works in a vacuum environment. It is mainly used in the semiconductor industry to realize the transfer of wafers in a vacuum chamber. Vacuum manipulators are difficult to import, are restricted, have a large amount of use, and have strong versatility. They have become a key component that restricts the research and development progress of the semiconductor equipment and the competitiveness of the complete product.

 

8. Clean robot

A clean robot is an industrial robot used in a clean environment. As the level of production technology continues to improve, its requirements for the production environment are becoming increasingly demanding. Many modern industrial products are required to be produced in a clean environment. Clean robots are the key equipment required for production in a clean environment.
