Truss manipulator is an initial industrial robot and also an initial modern robot. At present, domestic machinery is mainly used in machine tool processing, casting and forging, heat treatment, etc., and its quantity, variety and performance cannot meet the needs of industrial production development. According to the China Robotics Industry Alliance, the sales volume of industrial robots in China has reached 36560, up 60% year on year, and has surpassed Japan as a global robot power. Manipulators have many advantages, such as automatic loading and unloading instead of manual operation, which can well control the beat, avoid the impact of human factors on the production beat, and greatly improve the production efficiency. The production process can be changed quickly by modifying the program and the gripper fixture, and the debugging speed is fast, eliminating the time for staff to be trained, and the production can be put into production quickly. Robotic automatic production line, from feeding, clamping, blanking is completely completed by robots, reducing the intermediate links, greatly improving the quality of parts, especially the workpiece surface is more beautiful. Taking the extraction process of injection molding parts of injection molding machine as an example, the workshop truss manipulator can imitate some motion functions of human arm, which is an automatic operating device used to grasp and transport objects or operate tools according to fixed procedures. The use of mechanical arms can reduce the workload of workers, improve labor productivity and workshop automation.

Now let's introduce the truss manipulator:

Truss manipulator is also called rectangular coordinate robot or gantry robot. Truss manipulator and CNC machine tool closely cooperate to form an unmanned loading and unloading machine processing system, which can greatly improve work efficiency and reduce labor costs. It is widely used in CNC lathes, machining centers, grinders, gear shapers, cleaning machines and other equipment for automatic loading and unloading. It is built by multi-dimensional linear guide rail The linear guide rail is composed of refined aluminum profile, toothed belt, linear sliding guide rail or gear rack. As a moving frame and carrier, the section shape of refined aluminum profile is optimized by finite element analysis, and its strength and straightness are guaranteed by lean production. The bearing smooth bar and linear sliding guide rail are used as the motion guide rail. The motion transmission mechanism adopts tooth belt, rack or ball screw. After many years of application and continuous improvement in various industries, various guideways have reached the world's top selection in reliability, noise reduction, bearing capacity, maintenance free and other aspects as well as overall performance.

Truss manipulator is a multi-purpose manipulator that can realize automatic control, repeatable programming, multi-function, multiple degrees of freedom, and spatial right angle relationship between degrees of freedom in industrial applications. He can carry objects and operate tools to complete various operations. Common organic bed loading and unloading robots, stacking robots, gluing (dispensing) robots, inspection robots, polishing robots, assembly robots, medical robots, etc. Good truss manipulators focus on the development of casting and heat treatment manipulators to reduce labor intensity and improve working conditions. While applying special manipulators, general manipulators should be developed accordingly. Teaching manipulators, computer controlled manipulators and combined manipulators should also be developed if conditions permit.

The increase of raw material cost, the increase of labor cost and the decrease of product market unit price. The profits of enterprises are getting thinner and thinner. If enterprises want to seek higher profits in this increasingly competitive society, they must reduce their production costs and improve their production efficiency. Therefore, it is an inevitable result of the development of social productivity for enterprises to install truss manipulators. "Machine replacement" is the only way to revitalize the manufacturing blocky economy, and the inevitable choice to promote industrial transformation and upgrading under the new normal of economy.
