Description

Technical Field

[0001] This invention belongs to the field of multilayer laminator technology, and particularly relates to a multilayer laminator and its silicone plate installation method. Background Technology

[0002] A photovoltaic (PV) module is a power generation device that produces direct current (DC) electricity when exposed to sunlight. It consists of thin, solid-state photovoltaic cells made almost entirely of semiconductor materials (such as silicon). The PV module laminator is a core piece of equipment in the PV module production process. Its function is to press tempered glass panels, EVA (Electrode Vapor Adhesive), solar cell strings, EVA, and a PV module backsheet, which are stacked sequentially, into a PV module using vacuum hot pressing. During vacuum hot pressing, the control of the heating process is extremely important. Therefore, the heating method of the laminator, the accuracy of temperature control during lamination, and the temperature uniformity directly determine the quality of the PV module.

[0003] In addition, in the multi-layer material pressing process, the multi-layer laminator is the core equipment. It achieves interlayer bonding of materials through the pressure of the pressing frame assembly and the heating of the heating plate. The silicone plate, as a buffer and heat conduction medium in the pressing process, needs to be tightly attached between the pressing frame and the material to be pressed. Its installation accuracy and tension directly affect the pressing quality.

[0004] Silicone sheets are consumables in laminating equipment. In current technology, the installation of silicone sheets largely relies on manual operation, requiring the disassembly of part of the frame structure. However, the following problems exist in actual operation: Cumbersome operation: Fixing and tensioning the silicone sheets requires multiple people working together and repeated adjustments, which is time-consuming. Moreover, replacing silicone sheets involves fixing the upper vacuum frame, usually using quick clamps and adapters to tighten screws for fixing and disassembly, which is time-consuming and labor-intensive. Difficult installation: In multi-layer laminators, the space for fixing the heating plate and the short side of the silicone sheet box to the frame is narrow, making it inconvenient to enter. The inability to manually install silicone sheets and fix the frame can easily lead to uneven tension, resulting in localized loosening or overstretching of the silicone sheets, affecting the consistency of lamination. Low adaptability: For silicone sheets of different sizes, multiple connectors need to be replaced, resulting in poor versatility.

[0005] Therefore, it is essential to invent a multi-layer laminator and a method for installing its silicone sheets. Summary of the Invention

[0006] To address the aforementioned technical problems, this invention provides a multilayer laminator and its silicone plate installation method, which enables rapid, uniform, and reliable installation and tensioning of the silicone plate, significantly improving maintenance efficiency and process stability.

[0007] The technical solution of the present invention is as follows: A multi-layer laminator includes a multi-layer laminator main frame stacked sequentially from bottom to top, and a lamination assembly is disposed in the laminator main frame; The laminated assembly includes a top plate and a bottom support plate. The top plate is located directly above the bottom support plate, and a pressure-relieving frame is connected to the bottom of the top plate. It also includes silicone sheet body mounting components symmetrically arranged on both sides of the rubber sheet box and pressure frame tensioning components symmetrically arranged, wherein the silicone sheet body mounting components are used to fix the silicone sheet body; The silicone sheet body mounting assembly includes a short-side pressure plate and a short-side tie rod, wherein the short-side pressure plate and the short-side tie rod cooperate to clamp the short-side edge of the silicone sheet body; The frame tensioning assembly includes a steel wire rope, a first tensioning screw, a traction guide tube, and a fixing base; The steel wire rope is threaded through the traction guide tube, the fixed seat is fixedly connected to the side wall of the rubber plate box, and the traction guide tube is fixedly connected to the fixed seat; tension plates are fixedly connected to both side walls of the force-releasing pressure frame, one end of the steel wire rope is connected to the tension plate, and the other end is connected to the first tension screw.

[0008] Preferably, a mounting plate is fixedly connected to the side wall of the box on the adhesive plate, and the first tensioning screw is threadedly connected to the mounting plate.

[0009] Furthermore, a support plate is fixedly connected to the side wall of the silicone sheet box. A second tensioning screw is threaded onto the support plate. The bottom end of the second tensioning screw is connected to the short side pull rod. By tightening the second tensioning screw, the short side pull rod is pulled upward, simultaneously stretching the silicone sheet body. By tensioning the first tensioning screw, the wire rope is tensioned and pulls the tensioning plate, causing the pressure relief frame to move upward and tighten. After the pressure relief frame is tightened and fixed, it is attached to the bottom wall of the silicone sheet body.

[0010] Furthermore, a connecting seat is fixedly connected to the pressure-relieving frame, and a tensioning screw is rotatably connected to the connecting seat. The tensioning screw is threadedly connected to the support plate.

[0011] Furthermore, a connecting rope clamp is fixedly connected to the wire rope. The wire rope passes through the connecting rope clamp and the tensioning plate in sequence. The connecting rope clamp is used to fix one end of the wire rope passing through the tensioning plate. The connecting rope clamp achieves a fixed connection between the wire rope and the tensioning plate by clamping the wire rope.

[0012] A method for installing silicone sheets in a multilayer laminator, specifically including the following steps: Step 1: Assemble the silicone sheet body and the silicone sheet body mounting components; Step 2: Position the silicone plate main unit; Step 3: Stretch and tighten the silicone sheet body; Step 4: Tighten the pressure relief frame and fix the silicone plate body.

[0013] Preferably, in step one, the two short edges of the silicone sheet body are placed between the two sets of short edge pressure plates and short edge tie rods, and the short edge pressure plates and short edge tie rods are connected using mounting screws.

[0014] Preferably, in step two, the silicone sheet main unit assembled in step one is transferred to the lamination assembly, so that the silicone sheet main unit is laid horizontally between the glue plate box and the pressure relief frame; at the same time, the position of the silicone sheet main unit is adjusted so that the short side tie rod is aligned with the second tensioning screw on the side wall support plate of the glue plate box, and then the assembled short side tie rod is connected to the second tensioning screw.

[0015] Preferably, in step three, the second tensioning screw on the support plate is tightened. Since the bottom end of the second tensioning screw is connected to the short side tie rod, the short side tie rod can be pulled upward during the tightening process. When the short side tie rod moves upward, it drives the short side edge of the silicone sheet body to move upward synchronously through the fixed clamping action with the short side pressure plate, thereby stretching the silicone sheet body in the vertical direction and ensuring that the silicone sheet body is in a flat and wrinkle-free state.

[0016] Preferably, in step four, the first tensioning screw on the mounting plate is tightened, so that the steel wire rope passing through the traction guide tube is tensioned synchronously. The tensioned steel wire rope pulls the tensioning plates on both sides of the stress-relieving pressure frame, causing the stress-relieving pressure frame to move upward and tighten. When the stress-relieving pressure frame is tightened until its top wall is tightly attached to the bottom wall of the silicone plate body, the stress-relieving pressure frame is fixed, thereby realizing the installation and fixation of the silicone plate body. After the stress-relieving pressure frame is initially fixed, the stress-relieving pressure frame is locked and reinforced by rotating the tensioning screw on the connecting seat and using the threaded engagement between the tensioning screw and the support plate.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention uses modular assembly and external operation to cooperate with the operation. The silicone plate body can be pre-assembled with the short side pressure plate and the pull rod into a unit, and then tensioned and fixed by the first and second external tensioning screws. There is no need to disassemble the equipment frame, and a single person can complete the operation, which effectively shortens the installation time.

[0018] 2. In this invention, the first tensioning screw, the second tensioning screw, and the tensioning screw are all arranged on the outside of the side wall of the box on the rubber plate, with a reasonable installation distance from the main frame of the multi-layer press. Personnel do not need to enter the main frame of the multi-layer press, effectively avoiding the risk of mechanical damage during equipment operation or adjustment.

[0019] 3. In this invention, the second tensioning screw acts directly on the short edge of the silicone sheet body by abutting against the short side tie rod. Combined with the synchronous tightening of the pressure frame under the traction of the steel wire rope, this achieves uniform stretching of the silicone sheet body along the short side, reducing pressing defects caused by localized loosening.

[0021] The present invention will be further described below with reference to the accompanying drawings: Example: As attached Figure 1 To be continued Figure 6 As shown, the present invention provides a multi-layer laminator, comprising a multi-layer laminator main frame 1 stacked sequentially from bottom to top, and a lamination assembly disposed within the laminator main frame 1; The laminated assembly includes a top box 2 and a bottom box 3. The top box 2 is located directly above the bottom box 3, and a pressure-relieving frame 4 is connected to the bottom of the top box 2. It also includes silicone plate main body mounting components symmetrically arranged on both sides of the rubber plate box 2 and pressure frame tensioning components symmetrically arranged. The silicone plate main body mounting components are used to fix the silicone plate main body 8. The silicone sheet body mounting assembly includes a short side pressure plate 5 and a short side tie rod 6. The short side pressure plate 5 and the short side tie rod 6 cooperate to clamp the short side edge of the silicone sheet body 8. The frame tensioning assembly includes a wire rope 701, a first tensioning screw 2021, a traction guide tube 7, and a fixing seat 201; The wire rope 701 is threaded inside the traction guide tube 7 and is parallel to the left and right sides of the rubber plate box 2. The fixing seat 201 is fixedly connected to the side wall of the rubber plate box 2, and the traction guide tube 7 is fixedly connected to the fixing seat 201. Tensioning plates 401 are fixedly connected to both sides of the pressure relief frame 4. One end of the wire rope 701 is connected to the tensioning plate 401, and the other end is connected to the first tensioning screw 2021.

[0022] Reference Figure 3 , Figure 4 It should be noted that the silicone sheet body 8 is a silicone sheet body material with a size similar to that of the silicone sheet box 2. Its left and right edges are folded upward along the side length to form two short sides that can be clamped, so that the silicone sheet body 8 is U-shaped, and the bottom of the silicone sheet body 8 is the long side, and the two sides of the silicone sheet body 8 are the short sides.

[0023] An installation plate 202 is fixedly connected to the side wall of the outer box 2 of the rubber plate, and the first tensioning screw 2021 is threadedly connected to the installation plate 202.

[0024] Reference Figure 2 , Figure 5 A support plate 203 perpendicular to the direction of the mounting plate 202 is fixedly connected to the far end of the side wall of the box 2 on the rubber plate. A second tensioning screw 2031 is threaded onto the support plate 203. The bottom end of the second tensioning screw 2031 is connected to the short side pull rod 6. By tightening the second tensioning screw 2031, the short side pull rod 6 is pulled upward, which simultaneously stretches the silicone plate body 8. By tensioning the first tensioning screw 2021, the steel wire rope 701 is tensioned and pulls the tensioning plate 401, which drives the pressure relief frame 4 to move upward and tighten. After the pressure relief frame 4 is tightened and fixed, it is attached to the bottom wall of the silicone plate body 8.

[0025] A connecting seat 402 is fixedly connected to the pressure relief frame 4, and a tensioning screw 9 is rotatably connected to the connecting seat 402. The tensioning screw 9 is threadedly connected to the support plate 203.

[0026] A connecting rope clamp 7011 is fixedly connected to the wire rope 701. The wire rope 701 passes through the connecting rope clamp 7011 and the tension plate 401 in sequence. The connecting rope clamp 7011 is used to fix one end of the wire rope 701 that passes through the tension plate 401. The connecting rope clamp 7011 achieves a fixed connection between the wire rope 701 and the tension plate 401 by clamping the wire rope 701.

[0027] Reference Figures 1-6In practical use, the silicone sheet body 8 is first pre-treated by folding its left and right edges upward along the side length to form short sides that can be clamped, so that the silicone sheet body 8 has a U-shaped structure. The short side edges of the silicone sheet body 8 are clamped between the short side pressure plate 5 and the short side pull rod 6, and the three are fixed together by fasteners such as screws to form a silicone sheet body 8 unit with installation components. The above assembly is completed on the left and right short sides of the silicone sheet body 8 respectively.

[0028] The assembled silicone sheet body 8 unit is then transferred to the lamination assembly of the multilayer laminator, so that the silicone sheet body 8 is laid horizontally on the rubber sheet box 2 and the pressure relief frame 4, ensuring that the position of the short side tie rod 6 is precisely aligned with the second tensioning screw 2031 on the side wall support plate 203 of the rubber sheet box 2. Then, the bottom end of the second tensioning screw 2031 is connected to the short side tie rod 6.

[0029] Reference Figure 3 , Figure 4 When tightening the silicone sheet body 8, the worker tightens the second tensioning screw 2031, which pulls the short side pull rod 6 upward. Using the clamping action of the short side pull rod 6 and the short side pressure plate 5, the short side edge of the silicone sheet body 8 moves upward synchronously, stretching the silicone sheet body 8 vertically until its surface is flat and wrinkle-free.

[0030] When the pressure relief frame 4 is tightened, the first tensioning screw 2021 on the mounting plate 202 is tightened. The tensioning plate 401 on the side wall of the pressure relief frame 4 is pulled by the steel wire rope 701 passing through the traction guide tube 7, which drives the pressure relief frame 4 to move closer to the rubber plate box 2 and tighten. After the top wall of the pressure relief frame 4 is in contact with the bottom wall of the silicone plate body 8, the tensioning screw 9 is tightened. The screw is used to lock and fix the pressure relief frame 4 by its threaded engagement with the support plate 203, thereby completing the installation and fixation of the silicone plate body 8 and the pressure relief frame 4.

[0031] This embodiment also provides a method for installing the silicone plate of the multilayer laminator, referring to... Figure 7 As shown, the specific steps include: Step 1: Assemble the silicone sheet body and the silicone sheet body mounting components: Place the two short edges of the silicone sheet body 8 between the two sets of short edge pressure plates 5 and short edge tie rods 6, and connect the short edge pressure plates 5 and short edge tie rods 6 with mounting screws; Step 2: Positioning the silicone sheet main unit: Transfer the silicone sheet main unit assembled in Step 1 into the lamination assembly, so that the silicone sheet main body 8 is laid horizontally between the outer box 2 of the outer box 2 and the pressure relief frame 4; at the same time, adjust the position of the silicone sheet main unit so that the short side tie rod 6 is aligned with the second tensioning screw 2031 on the side wall support plate 203 of the outer box 2 of the outer box 2, and then install and connect the assembled short side tie rod 6 to the second tensioning screw 2031; Step 3: Tighten the silicone sheet body: Tighten the second tensioning screw 2031 on the support plate 203. Since the bottom end of the second tensioning screw 2031 is connected to the short side tie rod 6, the short side tie rod 6 can be pulled upward during the tightening process. When the short side tie rod 6 moves upward, it drives the short side edge of the silicone sheet body 8 to move upward synchronously through the fixed clamping action with the short side pressure plate 5, thereby achieving the tightening of the silicone sheet body 8 in the vertical direction and ensuring that the silicone sheet body 8 is in a flat and wrinkle-free state.

[0032] Step 4: Tighten the pressure relief frame 4 and fix the silicone plate body 8: Tighten the first tensioning screw 2021 on the mounting plate 202 to simultaneously tension the steel wire rope 701 passing through the traction guide tube 7. The tensioned steel wire rope 701 pulls the tensioning plates 401 on both sides of the pressure relief frame 4, causing the pressure relief frame 4 to move upward and tighten. When the pressure relief frame 4 is tightened until its top wall is tightly attached to the bottom wall of the silicone plate body 8, the pressure relief frame 4 is fixed, thereby realizing the installation and fixation of the silicone plate body 8. After the pressure relief frame 4 is initially fixed, the tensioning screw 9 on the connecting seat 402 is rotated to lock and reinforce the pressure relief frame 4 by utilizing the threaded engagement between the tensioning screw 9 and the support plate 203.
