[0024] The PLC controller 12 is fixedly arranged on the side wall of the support 5, and the conveyor 2, the hydraulic cylinder 3, the pressure monitoring and dynamic compensation mechanism 9, the pressure abnormality counting mechanism 10 and the cooling mechanism 11 are electrically connected with the PLC controller 12.
[0025] The operating principle of the application is described as follows: first, the workers accurately place the lower glass, the film and the upper glass in the pressing box 6 in sequence, ensuring that the positions of the layers are aligned, then, through manual operation of the PLC controller 12, the conveyor 2 system is started, the conveyor belt of the conveyor 2 runs smoothly at a constant linear speed of 0.5 m / min, so that one of the pressing boxes 6 moves to the lower side of the pressing plate 4, and the other pressing box 6 moves outward until the sealing connection pipe 16 on the side wall of the pressing box 6 is sealingly connected with the second air pipe 113 at the corresponding position, at this time, the side wall of the pressing box 6 contacts the button of the travel switch 117 at the corresponding position, the travel switch 117 feeds back an electrical signal to the PLC controller 12, so that the PLC controller 12 immediately stops the conveyor 2, so that the pressing plate 4 and the pressing box 6 are automatically positioned, and the hydraulic cylinder 3 is controlled to extend, so that the piston rod of the hydraulic cylinder 3 vertically moves downward at a constant speed of 5 mm / s, driving the pressing plate 4 to synchronously descend to the inside of the pressing box 6, after the pressing plate 4 contacts the surface of the upper glass, the PLC controller 12 applies pressure according to the preset pressure curve (such as first pre-pressing at an initial pressure of 50 kN for 5 s, and then gradually increasing to 150 kN for 30 s) through a closed-loop control algorithm, to ensure that the lower glass, the film and the upper glass complete the pressing in a uniform pressure field; During the pressing process, the multiple trays 8 on the lower surface of the lower glass synchronously bear the extrusion force and displace downward, driving the corresponding supporting rods 92 to synchronously move downward, the lower end of the supporting rod 92 acts on the pressure sensor 93, the pressure sensor 93 compresses the first spring 96 through the permanent magnet block 94, to avoid damage to the pressure sensor 93 due to rigid force, this multi-point detection structure can collect the extrusion external force of each area of the glass pressing surface in real time, and each pressure sensor 93 transmits the detection signal to the PLC controller 12 to form a pressure data matrix; When the upper glass and the lower glass appear to be insufficiently stressed in some areas, the electrical signal value fed back by the corresponding position pressure sensor 93 decreases, the PLC controller 12 identifies the abnormal area through a preset threshold algorithm, and immediately sends a power-on instruction to the power-on permanent magnet block 95 at the area, the power-on permanent magnet block 95 generates an upward repulsive force with the permanent magnet block 94, driving the permanent magnet block 94 to move the push rod and the tray 8 upward, to apply supplemental external force to the insufficiently stressed area, during the dynamic compensation process, the pressure sensor 93 continuously feeds back the real-time pressure value until the pressure of the area and the global pressure are close, to ensure that the upper glass and the lower glass are uniformly stressed during the pressing process, promote the film to melt comprehensively, and improve the bonding strength of the upper glass and the lower glass to the process standard; In the pressing process, if the upper and lower layers of glass have local excessive force, the corresponding pressure sensor 93 detects a sudden increase in the value and transmits it to the PLC controller 12. The PLC controller 12 compares the pressure data of each area in real time, and when the pressure value of a single area exceeds the preset threshold, it immediately triggers the retraction command of the hydraulic cylinder 3, and simultaneously terminates the pressing action. At this time, the tray 8 in the area with excessive force is out of the normal range of downward distance, and its lower surface touches the touch head of the touch switch 105, triggering the touch switch 105 to send a pulse signal to the pulse counter 104, and at the same time pushing the moving rod 102 to compress the second spring 103 into the fixed sleeve 101. The second spring 103 deforms to absorb impact energy, achieving buffer protection for the touch switch 105 and the pulse counter 104. The pulse counter 104 completes counting once for every pulse signal received and feeds back the counting signal to the PLC controller 12, which synchronously updates the count on the display screen. When the count of a single position reaches the set value, the PLC controller 12 determines that there is a persistent pressure anomaly in that area and immediately activates the built-in alarm to issue an audible and visual alarm. At the same time, the corresponding energized magnetic block 95 is energized, generating a magnetic repulsive force to push the permanent magnet block 94, push rod, and tray 8 upwards. The protruding tray 8 directly indicates the fault position through mechanical markers, making it easy for workers to quickly locate and maintain. The entire process realizes immediate response to pressure overload, count tracing, and fault positioning, ensuring the safe and stable operation of the pressing device. In the pressing process, the workers simultaneously load another set of upper layer glass, film, and lower layer glass into the standby pressing box 6. When a set of pressing is completed, the operator operates the PLC controller 12 to start the conveyor 2, and the conveyor belt moves the pressed glass outwards at a constant speed while conveying the glass to be pressed under the pressing plate 4, realizing parallel operation of pressing and material taking, and greatly improving production efficiency. During the movement of the pressing box 6, the sealing connection pipe 16 on the side wall automatically completes the sealing insertion with the second air pipe 113, and at the same time, the pressing box 6 side wall triggers the travel switch 117, which feeds back an electrical signal to the PLC controller 12, causing the PLC controller 12 to immediately stop the operation of the conveyor 2, ensuring the accurate positioning of the pressing plate 4 and the new pressing box 6. At the same time, the PLC controller 12 starts the air blower 111 and opens the electromagnetic switch valve 115 of the corresponding second air pipe 113. The airflow generated by the air blower 111 enters the air cavity 13 in the side wall of the pressing box 6 through the first air pipe 112, the second air pipe 113, and the sealing connection pipe 16, and forms a laminar flow through the uniformly distributed air blowing holes 14, forcibly convecting the pressed glass. This process can accelerate the heat dissipation of the glass surface and the film layer, prevent the film from aging or the glass from stress concentration caused by high temperature, and at the same time, exhaust the hot and humid air in the box through the exhaust holes 15 to form a complete cooling airflow circulation. When the travel switch 117 is separated from the pressing box 6, the PLC controller 12 immediately stops the operation of the air blower 111 and closes the corresponding electromagnetic switch valve 115.
[0026] The above merely describes preferred embodiments of the present application and is not used to limit the present application, and any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
