l) The issue of safety protection for injection molding machine manipulators. A robotic arm is not an independent machine device, it must cooperate with the injection molding machine to operate and communicate with the injection molding machine in real-time. In terms of safety protection, in-depth analysis and design concepts should be carried out. If safety issues are not solved properly, the logic of the injection molding machine's manual operation will be poor, and it is more likely to cause danger. Therefore, a comprehensive and in-depth analysis of the safety issues of the injection molding machine's robotic arm is necessary to make a safe and reliable injection molding machine robotic arm.
(2) The working efficiency of the injection molding machine manipulator: The working efficiency of the injection molding machine manipulator largely determines the working efficiency of the injection molding machine. Only by effectively shortening the time for the manipulator to perform the removal action can the opening and closing time of the injection molding machine be further shortened, thereby improving the working efficiency of the injection molding machine. Currently, the manipulator still occupies a long time in the injection molding machine, and repeated on-site tests are needed to find the most effective method.
(3) Mechanical structure issues of large injection molding machines. There are various specifications of injection molding machine manipulators, which need to be matched with the selected injection molding machine for operation. The larger the specification of the manipulator, the worse the stability of operation. How to improve the stability of the mechanism of large manipulators has always been a problem that troubles the entire industry. In the future, a comprehensive performance index analysis of large manipulators will be conducted to solve the stability problem of large manipulators.
(4) Reliability issues with injection molding machines. Although the control system for the injection molding machine manipulator has been developed, the performance indicators are not yet perfect, and the stability of the manipulator operation still needs to be improved. There are still many non-standard factors in the development of human-machine interface and control applications, which need to be repeatedly modified during the actual testing process in order to develop a stable and reliable robotic arm control system.
Injection molding machine manipulator is a development trend of specialized manipulator for injection molding machines, and the application field of injection molding machine manipulator will have broad development prospects.
