Small inclined arm manipulator
A, the classification of injection molding manipulator
Manipulators suitable for injection molding industry can be divided into the following two types according to intelligence: 1 and basic injection molding manipulator: this kind of manipulator generally includes fixed mode program and teaching mode program according to production process requirements. Fixed mode program covers several standard processes of injection molding production at present, and uses industrial controller to do simple, regular and repetitive actions. The teaching mode program is especially suitable for injection molding machines with special production technology. By arranging basic actions in an orderly and safe way, the purpose of taking things smoothly can be achieved. 2. Intelligent injection manipulator: This kind of manipulator generally includes multi-point memory placement, standby at any point, more degrees of freedom and other functions. Generally, it adopts servo drive, which can simulate people to perform complex operations to the maximum extent, and can also be equipped with advanced sensors to make it have visual, tactile and thermal functions. It is a highly intelligent injection robot.
Second, the composition of injection molding manipulator
The composition of injection molding manipulator is generally composed of execution system, driving system and control system. The execution and driving system is mainly designed to complete the normal function of the arm, and the mechanical part is driven by pneumatic or hydraulic pressure to realize the function of taking things. The control system controls the drive system to make the execution system run according to the predetermined process. Take the control system of a simple manipulator as an example: the man-machine interface → the signal after the injection molding machine opens the mold → the signal of the single chip microcomputer → the signal of the injection molding machine manipulator → various valve signals ↓↓↓↓ The operator who executes the cylinder operates through the man-machine interface. When the manipulator receives the executable signal from the injection molding machine, the manipulator cuts off the clamping signal of the injection molding machine to ensure the safety of the manipulator to take things, and the manipulator resumes the action of the injection molding machine after taking things. The design difficulty of control system lies in the coordinated working relationship between manipulator and injection molding machine. Under the command of the control system, the manipulator completes various actions according to the predetermined working procedures, so as to take the products produced by injection molding out of the mold and transfer them to the designated place or the next production process. The control system should be determined according to the performance of the injection molding machine, the working conditions and requirements of the manipulator, the shape and weight of the product, etc.
Third, the application of manipulator in injection molding industry
Because the injection manipulator can greatly improve the productivity and reduce the production cost, it can stabilize and improve the quality of injection products and avoid the loss caused by human error. Therefore, the role of injection manipulator in injection molding production is becoming more and more important. At present, the types of domestic manipulators are relatively single, and most of them are used to pick up parts. With the development of injection molding industry, more and more robots will be used in various processes, such as feeding, mixing, automatic loading and unloading of molds, waste recycling and so on. And will develop in the direction of intelligence.
