The touch screen 4 displays the status of the tooling fixture cylinder and the sensor, which is convenient for the operator to judge the clamping situation. A pair of safety light curtains are installed on both sides of the station. When the mold enters the working area, the safety light curtain gives a signal to the PLC control system. After the upper limit sensor of the line body triggers the in-place signal, the robot body 1 starts to run the program. The touch screen 4 sets the management authority. Different operation authorities set different management modes. Each management authority sets a management password. Only with the password of the corresponding management authority can the corresponding operation mode be entered. The PLC communicates with the slave station through the bus network, collects the status information of each sensor and proximity switch, performs logical processing, and then transmits it to the output devices such as the solenoid valve and the indicator light for the control of the fixture, the display of the indicator light and other operations. The control system is equipped with a reserved MES interface, and the equipment control system reserves one or more free Ethernet interfaces for the MES manufacturing execution system equipment information integration; through the MES system data acquisition interface, the MES system can collect real-time data information of the overall equipment control system; the data collected by the MES system includes: single-day production data information for more than half a year, single-piece processing time within a quarter, real-time processing data parameter extraction, equipment maintenance data, equipment early warning data, lubrication reminders and maintenance records, fault frequency and processing records, real-time working condition data, auxiliary parts consumption data, energy consumption data and quality management data, etc.

[0029] In this embodiment, when in use, the actions of all the moving parts of this unit are based on the database data provided by the production factory to manually select the mold code or the code data is read by the code reader. When the mold is placed on the line, the code reader reads the data and sends the data to the product database in the PLC control system. The control system compares the collected data with the data in the database, and then the line transports it to the specified position. At the same time, the robot selects the corresponding subroutine according to the product data. The robot starts to move and outputs a signal to the PLC at the same time. The PLC controls the operation of the dust collection system; after cleaning is completed, a signal is output to the PLC, the PLC controls the dust collection system to stop, the line limit is opened, and the mold enters the next sequence of processing.

[0030] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
