一. Injection molding industry and development
With the development of China's plastics industry, the annual growth rate of China's plastic machinery industry has been around 30% in recent years, and the growth rate of profit margin is much higher than the growth of industrial output value. It is one of the fastest growing industries in China's machinery industry. . At present, the plastic processing machinery produced in China can meet the basic needs of the country, but with the world's advanced level i; BL匕, China's plastic processing machinery still has a certain gap in terms of quality stability, product accuracy and automation.
The status quo of China's plastic processing machinery: As an important technical equipment, plastic processing machinery is widely used in building materials industry, packaging industry, electrical and electronic information industry, agriculture, automobile and transportation, light industry, petrochemical industry, machinery industry, national defense industry, etc. The various sectors of the national economy and the various areas in which people live have increasingly shown an extremely important role in the national economy.
The injection molding machine is the largest variety of plastic machines in China with the largest output and application. It is also the main exporter of plastic presses in China. In the late 1950s, China produced the first injection molding machine. However, due to the low technical content of the equipment at that time, only general-purpose plastics could be used to produce daily necessities with lower technical requirements, such as plastic boxes, plastic drums, and plastics. Pots and so on. Injection molding technology is developing rapidly, and new technologies and new equipment are emerging one after another. High computerization, automation, single-machine multi-function, diversified auxiliary equipment, rapid combination and easy installation and maintenance will become a trend. All-electric injection molding machine, oil-electric composite injection molding machine, gas-assisted and water-assisted injection molding technology, and multi-layer injection molding technology. Special injection molding machines for preforms, optical discs, magnetic materials and thin-walled products for the production of special engineering plastics will become increasingly important. Large-scale, ultra-large injection molding machines for the development of heavy industries such as automobiles will also have greater demand.
With the rapid development of injection molding machine technology and technology, the factory automation level is getting higher and higher, so the injection molding robot will soon be popularized, mainly used for the injection molding of injection molding machine, which can reduce the workload of workers and improve the workload. Labor productivity and level of workshop automation. At present, the technology has just started in China, basically using imported equipment, thus limiting the development of domestic technology. The successful development and putting into use of the injection molding robot has promoted the localization of the automation equipment of the injection molding production line, enhanced the competitiveness of domestic enterprise products in the international market, and became the new economic growth point of the auxiliary machine industry of injection molding machines, through the continuous development of injection molding robots. It can drive the development of automated factory auxiliary equipment such as conveyor belts, thus forming a larger industrial chain and promoting the development of the entire injection molding industry.
Second, the application of the robot in the injection molding industry
With the rapid development of the plastics processing industry in China, the degree of automation of injection molding equipment is also increasing. Modern injection molding machines are often equipped with robots to increase production efficiency. The injection molding robot is an automated production equipment that can simulate some functions of the upper limbs of the human body and can be automatically controlled to transport the products or operate the tools according to predetermined requirements. The injection molding robot is specially equipped for the automation of injection molding production. It can reduce heavy manual labor, improve working conditions and safe production; improve the production efficiency of injection molding machines, stabilize product quality, reduce scrap rate, reduce production costs, and enhance enterprises. The competitiveness and other aspects play an important role.
The robots suitable for use in the injection molding industry can be classified into the following two types according to their intelligence level: 1. Basic injection molding robots, which generally include a fixed mode program and a teaching mode program according to the production process requirements. The fixed-mode program covers several standard processes for current injection molding, using industrial controllers for simple, regular and repetitive actions. The teaching mode program is specially designed for the injection molding machine with special production process, and achieves the purpose of successful material collection by orderly and safely arranging the basic movements. 2, intelligent injection molding robot, this type of robot generally includes multi-point memory placement, arbitrary point standby, more degrees of freedom and other functions, generally using servo drive, can carry out the most complex human-like execution of more complex operations, can also pass Equipped with advanced sensors, it has visual, tactile and thermal sensing capabilities, making it a highly intelligent injection molding robot.
The composition of an injection molding robot generally consists of an execution system, a drive system, a control system, and the like. The executive and drive system is designed primarily to perform the normal functioning of the arm, and to drive the mechanical components through pneumatic or hydraulic power to achieve the function of the object. The control system controls the drive system to operate the system according to a predetermined process, taking the control system of the simple robot as an example.
