LJTJ2030 Automatic Vertical Insulating Glass Sealing Robot Machine


LJTJ2030 Automatic Vertical Insulating Glass Sealing Robot Machine

Product Description

The automatic insulating glass sealing robot equipment adopts a large-screen touchscreen human-machine interface control system to realize automatic positioning of aluminum spacer frames for insulating glass, automatic pressing, conveying, automatic lifting and lowering of sealing, and automatic timing heating.

The use of advanced gas-liquid boosting technology makes the system pressure more stable and energy-saving. The system is equipped with an alarm system for running out of sealant, and a dual-group and dual-sealing supply configuration. Production will not be delayed during sealant replacement. The sealing head is adjustable within the range of 6-20mm and can be fine-tuned up and down.

The insulating glass sealing robot line is equipped with a thickness detection device and a depth detection device. The thickness and depth of the glass can be automatically detected through high-resolution precision sensors, thereby better saving raw materials. Coupled with the automatic sealaant replenishing function and automatic adjustment of glue output, the production efficiency can be greatly improved.

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, 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, and use the above formula to set Pn305 and Pn306.   

(3) Setting of basic operating functions  

Combined with the control requirements, the servo unit's control needs to always meet the servo ON 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, 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.
