Description

Technical Field

[0001] This utility model relates to the field of tempered glass technology, specifically to a laminating device for tempered glass production. Background Technology

[0002] Laminated glass, especially tempered glass as the base material, is widely used in building curtain walls, doors and windows, car windshields, furniture, and various high-end equipment panels due to its excellent safety, sound insulation, heat insulation, and impact resistance. Its manufacturing process typically involves sandwiching one or more layers of tough polyvinyl butyral (PVB) or ethylene-vinyl acetate copolymer (EVA) interlayer between two or more sheets of tempered glass. Through processes such as heating, pressurizing, and vacuuming, the glass and interlayer are firmly bonded together.

[0003] In the production of laminated glass, lamination is a crucial step that connects the glass and the interlayer film. Its quality directly determines the bonding strength, optical properties (presence of bubbles and impurities), and yield of the finished glass. Currently, existing lamination equipment has limited automation and requires a significant amount of manual labor to laminate the glass with the interlayer film. Summary of the Invention

[0004] The purpose of this invention is to address the problem in the prior art that manual lamination of the intermediate film is required, and to provide a laminating device for tempered glass production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a laminating device for tempered glass production, comprising: Roller conveyors are used to transport glass substrates along the production line direction. An intermediate film unwinding mechanism is located above the roller conveyor and is used to carry the intermediate film roll and release the intermediate film. An alignment component is provided on the output side of the intermediate film unwinding mechanism to clamp the end of the intermediate film and adjust its position so that the intermediate film is aligned with the end of the glass substrate. A fixing component, disposed on the roller conveyor, is used to clamp and fix the intermediate film after it is aligned with the end of the glass substrate, and can move synchronously with the glass substrate.

[0006] Furthermore, the intermediate film unwinding mechanism includes two opposing mounting frames, with an intermediate film mounting roller for mounting the intermediate film roll rotatably disposed between the mounting frames. Two tensioning rollers are also rotatably disposed in the output direction of the intermediate film mounting roller, and the intermediate film extends to the alignment assembly after passing around the two tensioning rollers in sequence.

[0007] Furthermore, the alignment assembly includes a displacement mechanism and a clamping mechanism; the clamping mechanism is installed at the output end of the displacement mechanism and is used to clamp the free end of the intermediate film, and moves in a controlled manner under the drive of the displacement mechanism, thereby achieving alignment with the end of the glass substrate.

[0008] Furthermore, the clamping mechanism includes Drive components; A clamping arm is connected to the output end of the drive unit and performs clamping or releasing actions under its drive. The clamping surface of the clamping arm is provided with clamping rollers.

[0009] Furthermore, the fixing assembly includes a lateral movement mechanism, an extension drive member, and a fixing plate; the extension drive member is mounted on the lateral movement mechanism, and the extension drive member is used to drive the fixing plate to move to be flush with the end of the glass substrate. The lateral movement mechanism is used to drive the extension drive member and the fixing plate to move together, so that the fixing plate presses the intermediate film tightly to the end of the glass substrate and can move synchronously with the glass substrate.

[0010] Furthermore, the lateral movement mechanism includes Guide rails are provided on the roller conveyor along the conveying direction of the glass substrate; A slider is slidably engaged with the guide rail, and an extension drive component is mounted on the slider. A drive source, connected to the slider drive, is used to drive the slider to move along the guide rail.

[0011] The beneficial effects of this invention after adopting the above technical solution are as follows: the entire alignment, clamping, and initial lamination process is fully automated by mechanical mechanisms, replacing the traditional method of relying on manual film pulling and alignment. The device is seamlessly integrated with the production line (roller conveyor), enabling the initial lamination process to be completed during the continuous conveying of glass substrates, greatly improving production cycle time and overall efficiency.

[0015] See Figure 1-4 As shown, the technical solution adopted in this specific embodiment is: a laminating device for tempered glass production, which includes... Roller conveyor 1 is used to transport glass substrates along the production line direction; Intermediate film unwinding mechanism 2 is located above the roller conveyor 1 and is used to carry the intermediate film roll and release the intermediate film. The mechanism includes two oppositely arranged mounting frames 21, with an intermediate film mounting roller 22 for mounting the intermediate film roll rotatably arranged between the mounting frames 21. Two tensioning rollers 23 are also rotatably arranged in the output direction of the intermediate film mounting roller 22. The intermediate film extends to the downstream alignment assembly 3 after passing around the two tensioning rollers 23 in sequence. Alignment component 3 is disposed on the output side of the intermediate film unwinding mechanism 2, and is used to clamp the end of the intermediate film and adjust its position so that the intermediate film is aligned with the end of the glass substrate. This component includes a displacement mechanism 31 and a clamping mechanism 32. The clamping mechanism 32 is installed at the output end of the displacement mechanism 31 and is used to clamp the free end of the intermediate film and move in a controlled manner under the drive of the displacement mechanism 31, thereby achieving alignment with the end of the glass substrate. The clamping mechanism 32 includes a drive member 321 and a clamping arm 322. The clamping arm 322 is connected to the output end of the drive member 321 and performs clamping or releasing actions under its drive. The clamping surface of the clamping arm 322 is provided with clamping rollers 323. A fixing component 4, disposed on the roller conveyor 1, is used to clamp and fix the intermediate film after it is aligned with the end of the glass substrate, and can move synchronously with the glass substrate. The component includes a transverse mechanism 41, an extension drive 42, and a fixing plate 43. The extension drive 42 is mounted on the transverse mechanism 41 and is used to drive the fixing plate 43 to move until it is flush with the end of the glass substrate. The transverse mechanism 41 is used to drive the extension drive 42 and the fixing plate 43 to move together, so that the fixing plate 43 presses the intermediate film against the end of the glass substrate and can move synchronously with the glass substrate. The transverse mechanism 41 includes a guide rail 411 disposed on the side wall of the roller conveyor 1 along the glass substrate conveying direction, a slider 412 (the extension drive 42 is mounted on the slider 412) that slides with the guide rail 411, and a drive source 413 that is drivenly connected to the slider 412 for driving the slider 412 to move along the guide rail 411.

[0016] The working principle of this utility model: Although not shown in the figure, this device should actually be equipped with sensors and a vision system.

[0017] Step 1: Preparation Phase Glass substrate placement: The tempered glass substrate is conveyed from the upstream process (cleaning and preheating) to the dust-free working area of ​​the laminating device via roller conveyor 1.

[0018] Intermediate film unwinding: The intermediate film unwinding mechanism 2 starts working, and the intermediate film roll rotates on the intermediate film mounting roller 22 to release the film. The film first passes through two tension rollers 23. The function of these two tension rollers 23 is: Provide a certain tension to prevent the film from loosening and wrinkling.

[0019] Change the film path to guide it smoothly to the alignment component 3 below.

[0020] Step Two: Alignment Phase Capturing the membrane end: Alignment component 3 begins operation. Its clamping mechanism 32 moves to the waiting position under the drive of displacement mechanism 31 (in this example, displacement mechanism 31 is a motor-driven slide). Then, drive component 321 (in this example, drive component 321 is a cylinder) actuates, pushing clamping arm 322 to close, clamping the free end of the intermediate membrane through clamping roller 323 on it.

[0021] Precise positioning: After the clamping mechanism 32 clamps the film end, the displacement mechanism 31 drives the clamping mechanism 32 to move downward so that the intermediate film is aligned with the end of the glass substrate on the lower roller 1.

[0022] Step 3: Fixing and Initial Fitting Stage Fixing component 4 in place: After the alignment operation is completed, fixing component 4 begins to work. The extension drive component 42 (such as a cylinder) is activated first, pushing the fixing plate 43 forward so that its working surface is flush with the end of the glass substrate.

[0023] Pressing and Fixing: Next, the drive source 413 (such as a servo motor or cylinder) of the transverse mechanism 41 is activated, driving the slider 412 to move along the guide rail 411 toward the glass. The slider 412 drives the extended drive member 42 and the fixing plate 43 to move forward together, finally pressing the fixing plate 43 smoothly onto the aligned ends of the intermediate film and the glass substrate. At this time, the intermediate film is firmly "clamped" between the fixing plate 43 and the glass. Then the clamping arm 322 releases the clamp and resets.

[0024] Step 4: Synchronous Film Laying Stage Roller conveyor 1 continues to operate, conveying the glass substrate forward.

[0025] The drive source 413 of the transverse mechanism 41 receives a synchronization signal and drives the slider 412 and the fixed plate 43 assembly to move synchronously at the same speed as the roller conveyor 1.

[0026] During this process, the fixing plate 43 always presses down on the end of the interlayer film, moving forward with the glass. This action is equivalent to a "traction head," smoothly "pulling" the interlayer film out of the unwinding mechanism and continuously laying it on the surface of the forward-moving glass substrate.

[0027] Step 5: Completion and Reset Completed Lamination: After the glass substrate has completely passed through the station and the intermediate film has been completely laid on the glass, the fixing plate 43 releases the pressure on the film end, and the transverse mechanism 41 drives it to quickly return to the initial position, ready for the next cycle.

[0028] Step Six: Cutting and Bubble Detection The intermediate film is cut by staff (or the film cutting unit) and the presence of air bubbles between the intermediate film and the glass substrate is checked.

[0029] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
