Description

Technical Field

[0001] This utility model mainly relates to the technical field of glass deep processing equipment, specifically an automatic sealing strip machine. Background Technology

[0002] Laminated glass is a composite material made of glass or acrylic glass and high-quality engineering plastics through special processing. It is usually transparent and typically consists of polycarbonate fiber layers sandwiched between ordinary glass layers. Its engineering plastic inner layer can absorb some of the energy and shock wave pressure generated during impacts and explosions, preventing shattered glass from scattering. Laminated glass can be made from ordinary glass, tempered glass, or heat-strengthened glass, and can also be made into insulated glass units, depending on the specific needs. Laminated glass offers good safety, impact resistance, and penetration resistance, and provides anti-theft, laminated, and explosion-proof functions.

[0003] For laminated glass used in building doors and windows, precise and quickly adjustable pressure needs to be applied to the adhesive strip during the molding process to ensure that there are no air bubbles or wrinkles between the PVB film and the glass, and to achieve the ideal bonding effect. Existing adhesive strip pressing machines are insufficient in terms of the response speed and accuracy of pressure adjustment, as well as adaptability to glass of different sizes and shapes, resulting in low production efficiency and low product qualification rate.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] like Figure 1-4 The diagram shown is a schematic diagram of the relevant structure of an automatic adhesive strip machine provided in this embodiment.

[0023] like Figure 1 As shown, an automatic sealing strip pressing machine includes a frame 1, which supports the entire structure of the equipment, ensuring its stability and accuracy. A glass support platform 2 is located at the bottom of the frame 1 for placing semi-tempered laminated glass for architectural use to be formed. A slide rail bracket 7 is located at the top of the frame 1 for easy horizontal movement. A sliding platform 8 is mounted on the slide rail bracket 7, and a sealing mechanism 9 is located at the bottom of the sliding platform 8. The sealing mechanism 9 is positioned above the glass support platform 2 and applies pressure to the sealing strip at the edge of the glass. A control system 16 is located on one side of the frame 1.

[0024] The control system 16 includes a PLC (Programmable Logic Controller), an industrial computer, and a human-machine interface 26. The control system 16 is connected to the hydraulic lifting column 3. The control system 16 is responsible for receiving parameters such as glass size, adhesive strip type, and required pressure curve input by the operator. Based on the preset program and feedback from the high-precision pressure sensor 12, it calculates and outputs control signals to the fast-response proportional valve 14 in real time to achieve closed-loop pressure control. It controls the up-and-down movement of the adhesive pressing mechanism 9 and the lifting or tilting of the glass support platform 2. The control system 16 has fault diagnosis and alarm functions.

[0025] like Figure 2As shown, a hydraulic lifting column 3 is provided at the bottom of the glass support platform 2. The top of the hydraulic lifting column 3 is connected to the glass support platform 2 through a rotating joint 4. The rotating joint 4 is driven by a motor or cylinder to tilt. The glass support platform 2 can be designed to be liftable or tiltable to accommodate glass of different sizes and shapes and facilitate subsequent operations.

[0026] A vacuum suction cup 5 is provided on the upper surface of the glass support platform 2. When tilted, the glass is fixed by the vacuum suction cup 5 or a clamp to prevent it from slipping. An tilt sensor 25 is provided on the glass support platform 2. The tilt sensor 25 is connected to the control system 16. The tilt angle can be fed back to the control system 16 through the encoder or the tilt sensor 25. Mechanical stop blocks 6 are provided on the four sides of the glass support platform 2. The mechanical stop blocks 6 are equipped with a fall prevention device to prevent falling. A fixing screw 24 is provided on the mechanical stop block 6. A sliding groove 27 is provided between the fixing screw 24 and the glass support platform 2. The mechanical stop block 6 moves on the glass support platform 2 through the sliding groove 27 and is fixed in position by the fixing screw 24.

[0027] like Figure 3 As shown, the adhesive pressing mechanism 9 includes at least one adhesive pressing head 10, which is positioned above the glass support platform 2. The bottom of the adhesive pressing head 10 is provided with a flexible adhesive pressing pad 11 to accommodate minor unevenness at the edge of the glass. A high-precision pressure sensor 12 is provided on the adhesive pressing head 10 and installed in or near the adhesive pressing head 10 to facilitate real-time monitoring of the pressure applied by the adhesive pressing head 10 to the adhesive strip. A hydraulic drive rod 13 is provided on the top of the adhesive pressing head 10 and is fixed on the sliding platform 8. The adhesive pressing head 10 moves up and down through the hydraulic drive rod 13.

[0028] A fast-response proportional valve 14 is installed on the hydraulic drive rod 13. The fast-response proportional valve 14 is connected to the hydraulic power source of the hydraulic drive rod 13 and to the control system 16. It is convenient to quickly and accurately adjust the air pressure or hydraulic pressure according to the instructions of the control system 16, thereby controlling the force applied by the pressing head 10. A feedback control unit 15 is installed on the sliding platform 8. The feedback control unit 15 is connected to the high-precision pressure sensor 12 and to the control system 16. The feedback control unit 15 receives the data from the pressure sensor and compares it with the preset pressure value. It sends the deviation signal to the control system 16 to realize the rapid and accurate adjustment of the pressure applied to the pressing head 10.

[0029] like Figure 4As shown, the slide rail bracket 7 includes a transverse gear slide rail 17, a transverse sliding groove 18 is provided on the transverse gear slide rail 17, a transverse rack 19 is provided in the transverse sliding groove 18, a sliding platform 8 is provided in the transverse sliding groove 18, a transverse motor 22 is provided on the sliding platform 8, the transverse motor 22 is connected to the transverse rack 19 through gears to facilitate the transverse movement of the pressing head 10, longitudinal gear slide rails 20 are provided on both sides of the transverse gear slide rail 17, longitudinal racks 21 are provided on the longitudinal gear slide rails 20, and longitudinal motors 23 are provided at both ends of the transverse gear slide rail 17, the longitudinal motors 23 are connected to the longitudinal racks 21 through gears to facilitate the longitudinal movement of the pressing head 10.

[0030] The working principle of this embodiment is as follows: The semi-tempered laminated glass for architectural use, awaiting molding, is placed on the glass support platform 2. The control system 16 initiates the pressing process according to preset parameters. The hydraulic lifting column 3 controls the glass support platform 2 to rise or tilt; the tilt angle is fed back to the control system 16 via the tilt sensor 25. Then, the pressing mechanism 9 is adjusted to a designated position via the slide rail bracket 7. The pressing head 10 of the pressing mechanism 9 descends and contacts the adhesive strip at the edge of the glass. A high-precision pressure sensor 12 monitors the pressure applied by the pressing head 10 in real time and feeds the data back to the control system 16. Based on the feedback data, the control system 16 precisely adjusts the hydraulic pressure of the hydraulic drive rod 13 via the fast-response proportional valve 14, thereby achieving rapid and dynamic adjustment of the pressure on the pressing head 10. The entire process forms a closed-loop control, ensuring that the adhesive strip is always under optimal stress during molding, effectively preventing the generation of bubbles and wrinkles, and improving the yield and quality of the laminated glass.
