Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and more specifically to a laminating device for producing laminated glass. Background Technology

[0002] The conventional production process of dry-laminated glass is as follows: Clean glass sheets are fed into the lamination chamber (a constant temperature and humidity environment). Workers wearing anti-static clothing and gloves operate the equipment. The glass conveyor conveys the bottom glass sheet, and then the film (PVB) is manually pulled from the roll and laid on the bottom glass. After cutting, the top glass sheet is placed manually or by a robot to form the initial laminated glass. The initial laminated glass is then transported to the pre-pressing equipment outside the lamination chamber by the glass conveyor to remove air and bond the film and glass together. After air removal, it is sent to the autoclave for heating and shaping. PVB film is a flexible polymer material. While it has slight adhesive strength at room temperature, it also possesses inherent flexibility. During installation, improper handling and film warping can easily lead to surface air residue, localized edge lifting, and slight wrinkles. If these issues are not addressed during the lamination stage, air will be trapped between the glass and the film after the subsequent glass layer is stacked. Even with subsequent pre-pressing and degassing processes, it's difficult to completely remove all trapped air, ultimately resulting in air bubbles in the finished product. Wrinkles and edge lifting cause discontinuous adhesion between the film and glass, leading to delamination and areas without adhesive after autoclaving. Pre-pressing and degassing after laying one layer of film can effectively solve these problems. However, currently, manual operation cannot effectively complete pre-pressing and degassing, hindering further improvements in product quality. Summary of the Invention

[0003] The purpose of this invention is to provide a lamination device for laminated glass production, which solves the product quality problem caused by the inability to effectively pre-press the film during the existing lamination process of laminated glass.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A laminating device for laminated glass production, comprising: Glass conveyor; The film holder includes two support frames located on both sides of the glass conveying table and a rotating roller detachably disposed between the support frames; An automatic film laying device includes a gantry frame that slides with the glass conveyor table along the conveying direction, a film clamping and pressing compounding mechanism mounted on the gantry frame, a film cutting mechanism mounted on the gantry frame, and a transverse drive mechanism mounted on the glass conveyor table and connected to the gantry frame for transmission; the gantry frame is located in front of the film conveyor in the film conveying direction, and the gantry frame spans across the glass conveyor table.

[0005] Furthermore, the film clamping and rolling laminating mechanism includes: The fixed roller frame includes two vertical plates arranged at intervals on the lower side of the portal frame crossbeam, a first roller shaft rotatably connected between the two vertical plates, and a rotary adjustment mechanism provided on the portal frame crossbeam and drivenly connected to the first roller shaft. The movable roller frame includes two connecting rods fixedly connected to a first roller shaft, a slider disposed on the connecting rods and elastically and slidably engaged along the length of the connecting rods, and a second roller shaft rotatably connected between the two sliders; the connecting rods are adjacent to the vertical plate; The elastic support mechanism is located on the underside of the crossbeam of the portal frame and elastically supports the slider.

[0006] Furthermore, the rotation adjustment mechanism includes: The first servo motor is mounted on the crossbeam of the gantry frame; The belt drive mechanism includes a first pulley on the output shaft of a first servo motor, a second pulley at one end of a first roller shaft, and a synchronous toothed belt connecting the first pulley and the second pulley.

[0007] Furthermore, a first spring is connected between the slider and the connecting rod, and the slider is sleeved on the sliding rod.

[0008] Furthermore, the elastic support mechanism includes: Two electric telescopic poles are provided and are vertically fixed on the crossbeam of the portal frame; The pressure block has a shaft hole in its middle and is sleeved on the output shaft of the electric telescopic rod. Its free end is provided with a U-shaped groove to hold the slider. The second spring is located inside the pressure block and is fixedly connected between the pressure block and the end of the output shaft of the electric telescopic rod.

[0009] Furthermore, the film cutting mechanism includes: The first linear guide rail is mounted on the portal frame; The first ball screw is rotatably connected to the portal frame via a bearing housing and is located above the first linear guide. The second servo motor is mounted on the gantry frame and is connected to the first ball screw drive. The tool holder includes a connecting seat that is connected to both a slide seat that is matched with the first linear guide and a nut seat that is matched with the first ball screw, a servo motor that is mounted on the connecting seat, and a cutting tool that is mounted on the output shaft of the servo motor.

[0010] Furthermore, the lateral movement drive mechanism includes: The second ball screw is rotatably connected to one side of the glass conveyor table via a bearing seat, and its matching screw nut seat is fixedly connected to the gantry frame. The third servo motor is fixed on the glass conveyor and connected to the second ball screw drive.

[0011] Furthermore, the glass conveying table is provided with second linear guide rails on both sides, and the slides of the two second linear guide rails are respectively connected and fixed to the two columns of the gantry frame.

[0012] Furthermore, a second linear guide rail is provided with two slidingly engaged limit seats, which are located on both sides of the portal frame along the moving direction of the portal frame.

The clamping function pulls the film to cover the glass sheet, and the rolling function presses the film flatly onto the glass sheet, improving the bonding tightness and achieving initial air release between the film and the underlying glass sheet, thus preventing wrinkles and warping. After the film is cut by the film cutting mechanism, it can cover the upper glass layer. Based on the rolling function of the film clamping and rolling laminating mechanism, rolling pressure can be applied again to increase the bonding tightness between the film and the glass sheet, ensuring effective adhesion between the film and the upper glass sheet. The addition and cutting of film during the lamination process can be completed automatically, improving automation and processing efficiency for the entire lamination process.

Detailed Implementation

[0016] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings.

[0017] like Figures 1 to 14 As shown, a laminating device for laminated glass production is disclosed. The device includes a glass conveyor table 1, a film holder, and an automatic film laying device. The automatic film laying device works in conjunction with the film holder to pull the film (PVB) from the film holder, simultaneously rolling and flattening the laid-up film and venting air. It can also roll the initially formed laminated glass, improving product quality; the mechanized film laying operation increases efficiency.

[0018] The glass conveyor table 1 is a commonly used piece of equipment in glass production and processing enterprises. It typically consists of a frame, a rotating shaft mounted on the frame, and conveyor rollers mounted on the rotating shaft, used to support and transport glass. This assembly device is an improved version of the glass conveyor table 1, requiring the glass conveyor table 1 to have a frame or fixed housing in the width direction for connecting guide rail components. If a suitable frame or housing does not exist, a suitable frame or housing can be added to the existing structure of the glass conveyor table 1 by welding.

[0019] The film holder is used to hold rolls of PVB film. The film holder includes two support frames 2 located on either side of the glass conveyor table 1 and a rotating roller 3 detachably positioned between the support frames 2. The support frames 2 are rod-shaped structures fixed to the floor of the assembly room by anchor bolts, or they can be fixed to both sides of the glass conveyor table 1 by bolt connections. The support frames 2 have multiple slot plates 4 evenly spaced along the longitudinal direction for engaging the rotating roller 3. The slot plates 4 have a U-shaped cross-section and are arranged at an angle. The rotating roller 3 has tapered shaft sections at both ends, with bearings mounted on the shaft sections. The bearings are engaged within the slot plates 4. This structure facilitates the disassembly of the rotating roller 3 for mounting the PVB film roll and provides good rotational characteristics.

[0020] The automatic film laying device semi-automatically completes the film laying operation. Based on its built-in roller pressing function, it ensures that the film is effectively flattened on the glass sheet and achieves pre-venting after laying. The automatic film laying device includes a gantry frame 5, a film clamping and roller pressing composite mechanism, a film cutting mechanism, and a transverse drive mechanism. The gantry frame 5 slides with the glass conveyor table 1 along the conveying direction. The movement distance of the gantry frame 5 is controlled by the transverse drive mechanism. The gantry frame 5 is located in front of the film conveyor in the film conveying direction and straddles the glass conveyor table 1. The film clamping and roller pressing composite mechanism integrated on the gantry frame 5 is used for both clamping and pulling the film after laying, and for roller pressing, flattening, and venting after laying. The film cutting mechanism moves along the gantry frame 5 to cut the film.

[0021] The gantry frame 5 consists of two uprights and a crossbeam connecting the uprights; the uprights are actually plate-like structures. Second linear guides 6 are provided on both sides of the glass conveying table 1, and the sliding seats of the two second linear guides 6 are respectively connected and fixed to the two uprights of the gantry frame 5. At this time, the gantry frame 5 can move along the conveying direction (length direction) of the glass conveying table 1.

[0022] The film clamping and rolling laminating mechanism can clamp films and, structurally, can also roll-press laid films or glass sheets. The film clamping and rolling laminating mechanism includes a fixed roller frame, a movable roller frame, and an elastic support mechanism. The fixed roller frame includes vertical plates 7, a first roller shaft 8, and a rotation adjustment mechanism. Two vertical plates 7 are provided and welded to the underside of the crossbeam of the portal frame 5, with the two vertical plates 7 spaced apart. The first roller shaft 8 is rotatably connected between the two vertical plates 7. The rotation adjustment mechanism is located on the crossbeam of the portal frame 5 and is drively connected to the first roller shaft 8; the rotation adjustment mechanism is used to control the rotation angle of the first roller shaft 8. The rotation adjustment mechanism specifically includes a first servo motor 9 fixedly connected to the crossbeam of the portal frame 5 and a belt drive mechanism connected between the first servo motor 9 and the first roller shaft 8. A vertically arranged, plate-shaped motor base is fixedly connected to the lower side of the crossbeam of the portal frame 5, and the first servo motor 9 is fixed to the motor base by bolt and nut connectors. The belt drive mechanism can also be replaced by a gear drive mechanism. If a belt drive mechanism is used, a first pulley 10 is installed on the output shaft of the first servo motor 9, a second pulley 11 is installed at one end of the first roller shaft 8, and a synchronous toothed belt 12 is installed between the first pulley 10 and the second pulley 11. The movable roller frame includes a connecting rod 13, a slider 14, and a second roller shaft 15. There are two connecting rods 13, which are fixedly connected to the first roller shaft 8. The connecting rods 13 are close to the vertical plate 7, and the connecting rods 13 rotate by means of the rotation of the first roller shaft 8. The slider 14 is annular and sleeved on the connecting rod 13, sliding along the length of the connecting rod 13. A first spring 16 connects the slider 14 and the connecting rod 13, providing elastic engagement between them. When the slider 14 is pressed, it automatically returns to its original position. A second roller 15 is rotatably connected between the two sliders 14. The first roller 8 and the second roller 15 are positioned opposite each other. When the slider 14 is pressed, a clamping gap is formed between the first roller 8 and the second roller 15 to hold the film. The pressing sections of both the first roller 8 and the second roller 15 are covered with a rubber layer (Shore hardness 60~80HA) to prevent damage to the film and glass sheet. The elastic support mechanism includes an electric telescopic rod 17, a pressure block 18, and a second spring 19. Two electric telescopic rods 17 are provided and vertically fixed on the crossbeam of the portal frame 5; a pressure block 18 has a shaft hole in its middle and is sleeved on the output shaft of the electric telescopic rod 17; the free end of the pressure block 18 has a U-shaped groove for holding the slider 14; a second spring 19 is located in the shaft hole of the pressure block 18 and is fixedly connected between the pressure block 18 and the end of the output shaft of the electric telescopic rod 17. The stiffness of the second spring 19 is greater than that of the first spring 16. The electric telescopic rod 17 can elastically press the slider 14 by the cooperation of the pressure block 18 and the second spring 19, so that the first roller shaft 8 and the second roller shaft 15 can be elastically clamped.

[0023] The film cutting mechanism is used to cut film from the film roll. The film cutting mechanism includes a first linear guide 20, a first ball screw 21, a second servo motor 22, and a cutter holder. The first linear guide 20 is fixed at both ends to two columns of the portal frame 5, aligned with the length direction of the crossbeam. The first ball screw 21 is rotatably connected to the portal frame 5 via bearing seats and is located above the first linear guide 20. The second servo motor 22 is mounted on the upper side of the portal frame 5 and is drive-connected to the first ball screw 21; the second servo motor 22 is driven via a synchronous belt drive structure, which is the same as the belt drive structure between the first servo motor 9 and the first roller shaft 8. The cutter holder includes a connecting seat 23 that connects to both the slide seat matching the first linear guide 20 and the nut seat matching the first ball screw 21, a servo motor 24 mounted on the connecting seat 23, and a cutter 25 mounted on the output shaft of the servo motor 24. A short screw and a nut are welded to the output shaft of the servo motor 24. The blade 25 has a hole and is fitted onto the short screw. The nut and bolt threads engage to lock the blade 25 in place. A serrated structure is not suitable for cutting the film to avoid generating debris that could get into the laminated glass layers.

[0024] The lateral movement drive mechanism includes a second ball screw 26 and a third servo motor 27. The second ball screw 26 is rotatably connected to one side of the glass conveyor table 1 via a bearing housing, and its corresponding nut is fixedly connected to the gantry frame 5. A plate-shaped motor mount is welded to the side of the frame of the glass conveyor table 1, and the third servo motor 27 is fixed to this mount and driven by the second ball screw 26. This drive connection can be achieved through a coupling or a synchronous belt drive structure. The third servo motor 27 drives the second ball screw 26 to rotate, thereby moving the gantry frame 5.

[0025] To facilitate initial positioning of the glass sheet, two slidingly engaged limit seats 28 are provided on a second linear guide rail 6. The limit seats 28 are located on both sides of the portal frame 5 along the direction of movement of the portal frame 5. The limit seats 28 are equipped with a distance sensor 29 that cooperates with the portal frame 5 and a set screw 30 for locking relative to the second linear guide rail 6. The set screw 30 is threadedly engaged with the limit seats 28. An L-shaped limit plate 31 is also rotatably connected to the limit seat 28 near the support frame 2. The L-shaped limit plate 31 forms a 90° angle and can be flipped up above the glass conveying table 1 to abut the edge of the glass sheet.

[0026] like Figure 15As shown, the assembling device is equipped with an electrical control box 32, which houses a PLC controller and is equipped with an electronic touch screen connected to the PLC controller. The PLC controller is electrically connected to the electric telescopic rod 17, the distance sensor 29, the first servo motor 9, the second servo motor 22, the third servo motor 27, and the servo motor 24, forming a PLC control system. The aforementioned execution and feedback components can also be connected to the control system of the glass conveying table 1 or to the control system of the assembling chamber.

[0027] When the laminating device is used : First, thread a film roll of the appropriate size onto the rotating roller 3, and then install the rotating roller 3 onto the support frame 2. Loosen the set screw 30 to adjust the limiting seat 28 with the L-shaped limiting plate 31, so that the L-shaped limiting plate 31 is located 20-30cm in front of the film roll, and tighten the set screw 30 to lock the limiting seat 28; flip the L-shaped limiting plate 31 onto the glass conveying table 1. Adjust the distance between the other limiting seat 28 and the corresponding edge of the glass according to the size of the glass sheet, maintaining a distance of 10-15cm, and lock the limiting seat 28.

[0028] A robotic arm can be installed in the lamination chamber to place glass sheets onto the glass conveyor table 1. Alternatively, based on flexible production needs and cost-saving requirements, workers can also place the glass sheets onto the glass conveyor table 1. After placement, the bottom glass sheet has a right-angled edge abutting against the L-shaped limiting plate 31 and maintaining a close fit, achieving initial positioning. Then, the L-shaped limiting plate 31 is flipped to the outside of the glass conveyor table 1. Initially, the first roller shaft 8 and the second roller shaft 15 are arranged laterally at intervals. The worker pulls down the free end of the film and places it between the first roller shaft 8 and the second roller shaft 15, so that the lower edge of the film extends 5-8 cm outward relative to the first roller shaft 8. Through system control, the first servo motor 9 rotates at a fixed angle, thereby driving the connecting rod 13 from a horizontal position to a vertically upward position via the first roller shaft 8. After the first servo motor 9 completes its rotation, the electric telescopic rod 17 moves down a fixed distance under system control, causing the pressure block 18 to press down on the slider 14, thereby causing the second roller shaft 15 to press against and clamp the film with the first roller shaft 8. After the film clamping action is completed, the system automatically controls the third servo motor 27 to run. The third servo motor 27 drives the gantry frame 5 to move via the second ball screw 26, thereby pulling out the film. When the moving gantry frame 5 reaches the set distance from the corresponding approaching distance sensor 29, the third servo motor 27 stops running. At this time, the film is located above the bottom glass sheet and is covered. After the third servo motor 27 stops running, the system automatically controls the electric telescopic rod 17 to retract, releasing the contact between the pressure block 18 and the slider 14; the slider 14 resets under the action of the first spring 16, releasing the clamping action on the film. After the electric telescopic rod 17 retracts and completes its retraction action, the system controls the first servo motor 9 to drive the first roller shaft 8 to rotate. The connecting rod 13 rotates one revolution under the influence of the first roller shaft 8, at which point the clamped film is completely detached from the two roller shafts. After the connecting rod 13 rotates one revolution, the system continues to control the connecting rod 13 to rotate at a certain angle. The specific angle is determined based on the thickness of the glass sheet, ensuring that the second roller shaft 15 can press against the upper side of the film after the connecting rod 13 rotates. At this point, the connecting rod 13 is in a downward-sloping position. After the connecting rod 13 continues to rotate at a certain angle, the system controls the third servo motor 27 to rotate in the opposite direction, driving the moving frame to reset and move in the opposite direction. During the movement, the second roller shaft 15 rolls the film in a single direction, ensuring the film adheres to the lower glass sheet, preventing wrinkles and warping, and allowing air bubbles to escape between the film and the glass sheet. During the resetting and movement of the gantry frame 5, after the distance to the corresponding approaching distance sensor 29 reaches the set value, the third servo motor 27 stops running. The system controls the servo motor 24 to rotate a certain angle, so that the blade 25 initially cuts the film. Then, the system controls the second servo motor 22 to rotate, and drives the connecting seat 23 to move through the first ball screw 21, so that the film is completely cut off from the film roll by the blade 25. After the cutting is completed, the system controls the connecting seat 23 to reset, and at the same time controls the output shaft of the servo motor 24 to reverse and reset.After the entire cutting operation is completed, the system controls the third servo motor 27 to run and continue moving in the reset direction until the distance feedback from the distance sensor 29 reaches the set requirement. Then, the system controls the third servo motor 27 to stop running, completing the reset operation. The second roller 15 is completely detached from the glass sheet. The operator can then cover the film with the upper glass sheet, aligning the edges to complete the lamination operation. To ensure lamination quality, and based on switch control, the third servo motor 27 is restarted. The second roller 15 elastically presses against the upper glass sheet, triggering the gantry 5 and the corresponding distance sensor 29 to reset. After reset, the system controls the first servo motor 9 to run, causing the connecting rod 13 to rotate to a horizontal position before stopping, completing the lamination operation. The processed laminated glass is then transported to the next process step via the glass conveyor 1. When processing the next piece of laminated glass, the operator pulls the film appropriately to position it between the first roller 8 and the second roller 15. The above process is then repeated for the next piece of laminated glass.
