The System Structure and Hardware Selection
The system is mainly composed of mechanical and electrical parts. The newly-added tray and Y-axis guide rail in the mechanical part are newly-added structures. As shown in Figure 1.
1. Support table
2. Guide support beam
4. Glue gun fixing column
5. X-axis guide rail
6. Y-axis guide rail
The electrical system includes the upper computer control part and the lower computer. The upper computer completes the real-time display and control of the glue application process information. The lower computer PLC accepts the signal from the field sensor, executes the program to process the data, and drives the execution unit. The selection of the main components is shown in Table 1.

The Servo Unit Parameter Setting
The normal operation of the servo unit requires the relevant parameters to be set as follows:
(1) Setting of speed control mode
When the glue output of the glue dispenser is constant, the glue can be applied even when the servo motor speed is stable, so set the servo unit to speed control mode, that is, Pn000.1=0. Use the proportional relationship between input voltage and speed to set the speed input command. When the set speed command input is +9V, the forward speed of the motor is 1500r/min, and when the input is +3V, the forward speed of the motor is 500r/min. Pn300=900, the "rEF_0" attribute of Fn009 is set to "donE".
(2) Setting of start and stop time
To get smoother constant acceleration and deceleration, it is necessary to set its soft-start function. as shown in picture 2. In the figure, Pn305 is the time required for the motor to reach the maximum speed from the stopped state, Pn306 is the time for the motor to reach the maximum speed from the maximum speed, ta is the actual acceleration, TB is the actual deceleration, nN is the maximum speed or rated speed, and n is the actual Operating speed.
The voltage U and speed n of the PLC analog output signal meet:
According to experience, adjust the acceleration and deceleration time setting ta=tb=100ms, nN=1500r/min, use the above formula to set Pn305 and Pn306.
(3) Setting of basic operating functions
Combined with the control requirements, the control of the servo unit needs to meet the servo ON always effective, the forward and reverse control of the guiding support beam and the tray; over-travel protection; motor free-running stop and emergency stop. The parameters are set as:
Pn50A.1=0, Pn000.0=0, Pn50A.3=2, Pn50B.0=3, Pn001.1=2, Pn001.0=2.
The Software Development
(1) PLC software design
The PLC program adopts a modular design method and is completed with function blocks. FC1 is initialized, and the tray is reset through the magnetic sensor; FC2 collects information from the host computer and selects the operating speed of the servo motor according to the glass specifications determined by the host computer; the initial position of the FC3 glass is confirmed, and the optical fiber sensor detects whether to enter the automatic four sides Gluing process; FC4 four-side gluing function, the gluing process has 4 sequential states, state 1 is the X-axis, state 2 is Y axis, state 3 is X-axis and state 4 is Y-axis; FC5 Detect the arrival of the next glass. If it is detected within the set time, the specifications of the glass will be confirmed. If the next glass is not detected, the control process will be completed.
(2) MCGS configuration software design
The main screen of the host computer monitoring system includes four sub-screens: user login, manual/automatic control, communication test, history query, and printing. Before performing control or parameter setting, the communication connection between the PLC and the host computer needs to be tested. The start, manual, and automatic detection of all motors, as well as the detection of sensors, use the Light control to display the detection status, and the connection status is distinguished by color. After entering the manual/automatic control mode, first, select the glass specifications, determine the amount of glue and the motor running speed, and then enter the control mode. Each servo motor can realize forward and reverse manual/automatic, and there is an interlock between the two. In addition, the specifications, processing time, and servo alarm conditions of the coated glass are displayed, and historical data conditions can be inquired and printed.
