Jiangsu Tianqi Star robot to share: injection molding machine manipulator control system


Suzhou injection molding machine manipulator control system

The elements of manipulator control include work order, arrival position, action time, movement speed, acceleration and deceleration speed.

The control of the manipulator is divided into two kinds: point control and continuous trajectory control.

The control system can be designed using digital sequential control according to the requirements of the action. It must first prepare a program to be stored, and then according to the specified procedure, control the manipulator to work.

There are two ways of storing the program: separate storage and centralized storage. Separate storage is to store the information of various control factors in more than two kinds of storage devices, such as the sequence information stored in the latch plate, CAM drum, punch belt; Position information is stored in time relay, constant speed rotary drum, etc. Centralized storage is to store all the information of various control factors in a storage device, such as tape, magnetic drum, etc. This method is used in situations where sequence, position, time, speed, etc. must be controlled at the same time, that is, in the case of continuous control.

The latch plate is used in situations where a rapid change of program is required. Change a program only need to change a latch board limit, and the same plug-in can be used repeatedly; The program length of the perforated tape is not limited, but if an error occurs, it must be replaced entirely; The information capacity of the punch card is limited, but it is easy to replace, save and reuse; Magnetic cores and drums are only suitable for applications with large storage capacity. As for which control element to choose, it is determined according to the complex and precise procedures of the action.

For the manipulators with complex movements, a teaching-seeking and reproducible control system is adopted. More complex manipulators employ digital control systems, minicomputers, or microprocessor controlled systems. The control system is most used by the latch plate, followed by the CAM drum. It is equipped with a number of cams, each CAM assigned to a movement axis, rotating drum movement one week to complete a cycle.
