LJTJ2540Automatic Vertical Insulating Glass Sealing Robot Machine

Product Description

  • Equipped with a high-resolution precision photoelectric switch sensor that can detect glass thickness and sealing depth; the glass coating width can be automatically adjusted according to the input parameters. It is equipped with a Siemens PLC control system to realize automated transmission through servo motors and high-precision racks to ensure improvement in the glue coating accuracy of the equipment.

  • It is equipped with an automatic glue replenishing function and adopts a unique pressure plate dual-channel sealing gasket structure to supply glue hydraulically to make up for the problem of glue overflow in the two-component glue barrel. Through the pressure control of the hydraulic station, the hydraulic station can meet the quantitative supply of oil to the driving cylinder, thereby controlling the quantitative supply of white glue A component, and then adjusting the proportion of B component glue through mechanical linkage to ensure a quantitative supply of black glue. ; It can automatically adjust the amount of glue output, greatly improving the sealing efficiency and saving the amount of sealant.

  • The glue head adopts a new front glue head and has a special floating structure to ensure that the glue head does not damage the glass while meeting the requirements of a close fit with the glass. It can also adapt to the insulating glass within a certain range. Misalignment error; equipped with a glass pressing device to ensure safer movement of glass during transmission and gluing.

  • The three-layer insulating glass can be sealed with glue. When sealing three-layer glass, first apply glue to the insulating glass of the first cavity. After the sealing process of the first cavity is completed, the glue head will automatically adjust the angle and then apply glue to the second cavity. The insulating glass is coated with glue.

  • The V-belt adjustment structure can adjust the V-belt according to the thickness of different glass; it adopts a transmission method that combines high-quality and precise multi-row roller chains and V-belts. The rollers are in contact with the processed surface of the beam, so the friction is small and the transmission is smooth. High power; the glued glass runs smoothly, ensuring a good glue coating effect.

  • Equipped with a rubber head pressing device, the pressure of the mobile cylinder of the rubber head can be adjusted through a precision electrical proportional valve to achieve compression of the rubber head, so that the rubber head adheres to the glass more smoothly.

  • Equipped with a glue head centering structure, the glue head can be adjusted according to different thicknesses of glass. No matter how thick the insulating glass needs to be sealed, the glue nozzle can always be aligned with the center of the cavity of the insulating glass, resulting in a better glue effect.

  • Equipped with a cleaning function, when the sealing equipment is not used for a long time, the glue supply pipeline needs to be cleaned (glue flushing) to prevent the glue supply pipeline from being solidified. When the cleaning function is performed, the mixed glue in the mixer pipe will be discharged, which can better protect the pipeline and prevent the rubber pipe from solidifying.

  • When sealing the four corners of the insulating glass, the micro-glue filling function is optional to ensure the quality of the glue at the corners; the sealing effect can ensure that the edges of the insulating glass are full and air-free, the corners are full, and the four sides of the insulating glass are smooth and The sealant surface is smooth and even, no need for secondary corner trimming.

  • Equipped with a "connection" function to the insulating glass production line, the sealing line also has the functions of unilateral gluing, alarm prompts, automatic hazard determination, and equipment locking.

  • Servo motors, PLC controllers, low-voltage electrical appliances, sensors, and photoelectric switches are all from well-known foreign brands to ensure safe and reliable operation of the equipment and long service life; the human-machine operation interface is friendly and simple, making it more convenient for users to operate.
