Because the injection manipulator can greatly improve the production efficiency, control the production cost, stabilize and improve the quality of injection molding products, avoid the loss caused by human errors; Therefore, the injection manipulator in injection molding production function is more and more important; At present, the type of domestic manipulator is relatively simple, most of which is used for picking up parts; With the development of China's injection molding industry, in the future there will be more and more manipulator can be used for loading and unloading, mixing, automatic loading and unloading mold, recycling waste and other processes, and will continue to develop towards more intelligent research direction; In the application research process of manipulator, our main work shows the following objectives:
1. The manipulator takes out the products in the mold and replaces the original semi-automatic production to full-automatic production.
2. Mechanical arm mold external products, embedded parts (labeling, embedded metal, secondary molding, etc.);
3. Automatic packaging and storage after the manipulator is taken out;
4. Forming material automatic feeding system and waste recovery system;
5. Manipulator manufacturer control system and so on;
Injection manipulator control management system:
1. The elements of manipulator control mainly include the management of work development sequence, arrival position, action time, movement speed, speed, etc.
2. Manipulator control system is divided into point control and continuous trajectory control.
3. The control management system can be designed according to the requirements of the action, and can use The Chinese digital sequence control; It must first program storage, and then in accordance with the provisions of the program, control manipulator work.
4. The storage and management modes of the program are separated storage and centralized data storage. Separate storage is to store the information of various control factors in two or more storage devices, such as the time sequence information stored in the latch plate, CAM drum, punch belt, position information stored in the time relay, equal-speed drum, etc. Centralized storage is to store all the information of various control factors in the storage device, such as magnetic tape, magnetic drum, etc. This method of use sequence, location, time, speed, etc. must be controlled at the same time, that is, continuous control of the case, in the case of the program needs to quickly replace the use of latch board; The same plugin can be used over and over again; The length of a program with perforated tape can be unlimited, but if there are errors, the program must be replaced, however, it is easily replaced and saved, and can be reused; Cores and drums are only suitable for mass storage; The choice of control elements should be based on the complex process and the correct operation process.
5. For the manipulator with complex action, the reappearance control system is adopted. A system controlled by a digital control system, minicomputer, or microprocessor.
