The Process flow

The input conveyor is equipped with an automatic identification system for coated glass and Low-E glass, and has an automatic alarm and stop transmission functions when the film layer is wrong. The cleaning machine is equipped with an automatic switching cleaning function, Low-E glass cleaning frequency conversion function, oil-free lubrication transmission function in the cleaning machine, primary cleaning, secondary cleaning isolation function, water mist separation function in the splash drying area, cleaning outlet glass electrostatic Automatic release function (optional).

The process method

When producing equilateral-size glass, the first piece of glass after cleaning is parked on the upper frame machine, and the aluminum frame is accurately positioned on the X and Y axes by manually controlling the deceleration motor. The second piece of glass stops on the upper frame machine and waits for the positioning of the upper guide rod of the lamination machine, and then enters the lamination machine. The output conveyor is equipped with automatic stop and transmission functions, which can accurately judge whether the next stage of the turning table can be conveyed. The turning table is equipped with a stop-turning function. When the oversized glass cannot be manually transported, it can be instructed to automatically or manually turn over, and the oversized glass can be slid out of the turning table in parallel for the second seal.

The Air-floating Transmission Section

At present, with the development of technology and market demand, the insulating glass format of glass curtain wall buildings continues to expand and its thickness continues to become thinner. Therefore, the production technology of the automatic insulating glass production line is required to be higher. At present, large-sized hollow front flat glass is mostly transported by contact transmission rollers. These contact methods can easily cause scratches and contamination to the flat glass, and can easily cause the glass to break, thus seriously affecting the quality of the product and thus the production efficiency.

Figure 1 The Air-floating Transmission Section 1 Figure 1 The Air-floating Transmission Section 1 

Based on the phenomena of scratches and contamination that often occur among glass deep processing practitioners, LIJIANG Glass independently developed and produced an air-floating glass transmission section, which is used for air-floating transportation of large-scale glass, including a bracket and an air-floating transportation platform installed on the bracket. , the air flotation conveying platform is assembled and spliced by several air flotation conveying plates; several floating holes are distributed on the air flotation conveying plate, and a conveying channel is opened inside the air flotation conveying plate, and the conveying channel runs through the side of the air flotation conveying plate, Each of the floating holes is connected to a transportation channel inside the air flotation transport platform; the floating holes are in the shape of a funnel with an upward opening, and diversion grooves are evenly provided around the edges. The new air-floating glass transmission section has a simple structure, easy processing, and flexible operation. Through airflow control, specific airflow distribution can be achieved to achieve air-floating lifting with uniform lifting force, stable load-bearing of large glass, and convenient transportation.

The External Plate Pressing Structure Section

Most of the insulating glass plate pressing structures currently in use use ball screws and hydraulic pressure. In the actual production process, most of the production line equipment and transportation structures require the insulating glass to be transported at an angle, resulting in subsequent plate pressing. The structure is also tilted. After long-term use, the plate-pressed structure is prone to metal fatigue, causing the insulating glass to collide with the plate-pressed structure, causing fragmentation and delaying the production progress. Secondly, during the subsequent plate pressing process, the hydraulic pressure The mechanism and ball screw are easily prone to stroke deviation, resulting in uneven subsequent plate pressure, which may lead to loose sealing or fragmentation.

In response to this problem, LIJIANG Glass independently developed and produced an automated insulating glass outer sheet pressing production line using a plate pressing device. Through storage boxes, buffer rods, buffer springs, mounting blocks, balls and negative pressure suction cups, it can ensure During the process of extrusion and transportation, the insulating glass is in a relatively stable state and will not be dislocated, which avoids the problem of loose sealing and improves the quality stability of the product. Through the limiting frame, limiting rollers, plate surface and base, The working stroke of the limiting plate can be limited to avoid the problem of uneven force, which may lead to broken insulating glass or loose sealing.
