Description

Technical Field

[0001] This invention relates to the field of laminator pressing mechanism technology, specifically to a hard pressing mechanism and a soft pressing mechanism for a laminator. Background Technology

[0002] There are generally two types of laminating mechanisms: hard lamination and soft lamination. Currently, existing technologies are usually soft lamination. For example, CN114834138B discloses a lamination mechanism in which the lamination chamber is divided into an upper chamber and a lower chamber by a silicone pad. The shape of the silicone pad is changed by the change in air pressure vacuum between the upper and lower chambers (the air pressure in the upper chamber is controlled by the first air pumping and filling component, and the air pressure in the lower chamber is controlled accordingly by the second air pumping and filling component) to apply pressure to the solar cell module.

[0003] However, the existing technology has the following problems: 1) The flatness of the solar cell modules laminated by the soft pressing method is not high and the edge thickness is uneven; 2) Affected by the supply of vacuum and compressed air, once there are sudden factors such as vacuum depressurization or sudden interruption of compressed air, the lamination process cannot continue. After opening the cover, the silicone pad cannot be effectively separated from the solar cell module, making it impossible to repair the module in time, delaying the production progress and efficiency of enterprises, and increasing the cost of secondary repair of modules (materials, manpower, etc.); 3) It does not have the function of switching between soft pressing and hard pressing methods, that is, the existing structure is not universal, inconvenient to disassemble, replace and assemble, and has poor applicability.

[0004] Therefore, providing a high-quality and efficient hard pressing mechanism and soft pressing mechanism for a laminator is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0005] In view of this, the present invention provides a hard pressing mechanism and a soft pressing mechanism for a laminator, so as to at least solve one of the technical problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A laminator hard pressing mechanism includes an upper box, a pressure frame, and a quick clamp. The upper box and the pressure frame at its bottom are connected by the quick clamp. The mechanism also includes a sealing plate, a pressure plate frame, a hard pressure plate, a pressure frame flange, and a compression spring. The sealing plate is pressed between the upper box and the pressure frame, and has a through hole in its center. The pressure plate frame, the sealing plate, and the hard pressure plate are arranged from top to bottom and connected together by a first bolt. The pressure frame flange is located inside the bottom of the pressure frame and is connected by a second bolt. The compression spring is vertically installed between the hard pressure plate and the pressure frame flange.

[0008] By adopting the above technical solutions, the present invention produces the following beneficial effects:

[0009] By achieving hard pressing, the solar cell modules are subjected to more uniform stress, resulting in higher consistency in edge thickness after the solar cell modules are finished, and a higher yield rate in subsequent processes. At the same time, there is no need to replace the adhesive sheet, saving a lot of adhesive sheet consumables and labor costs, reducing downtime and improving equipment utilization.

[0010] Furthermore, the sealing plate has multiple round holes; the pressure plate frame has multiple countersunk holes corresponding to the positions of the round holes; the hard pressure plate has multiple threaded blind holes corresponding to the positions of the round holes; the first bolt is a countersunk bolt, which passes through the round hole and is threadedly connected to the threaded blind hole, such that the head of the countersunk bolt is located inside the countersunk hole.

[0011] The beneficial effect of adopting the above-mentioned further technical solution is to avoid the bolt head protruding from the pressure plate frame and occupying space.

[0012] Furthermore, the bottom of the pressure plate frame is provided with multiple arc-shaped sealing bosses; the outer perimeter of the pressure plate frame is covered with a silicone edging strip.

[0013] The beneficial effects of adopting the above-mentioned further technical solution are that the arc-shaped sealing boss facilitates sealing with the sealing plate, and the silicone edge strip serves as a secondary seal and protects the sealing plate from damage, extending its service life.

[0014] Furthermore, it also includes a low-profile bolt. The hard pressure plate includes a fixed frame and a hard pressure plate body that are distributed vertically and connected as a whole. The threaded blind hole is opened on the fixed frame. A limit groove is opened at the bottom of the fixed frame, and the top of the compression spring is located in the limit groove. The low-profile bolt is screwed on the flange of the pressure frame and extends into the compression spring.

[0015] The beneficial effect of adopting the above-mentioned further technical solution is that it limits the position of the compression spring, ensuring that it functions properly.

[0016] Furthermore, it also includes multiple vertically intersecting support beams, each of which is connected to the top surface of the rigid pressure plate body.

[0017] The beneficial effect of adopting the above-mentioned further technical solution is to improve the strength of the hard pressure plate body.

[0018] Furthermore, multiple rigid limiting strips are fixed to the periphery of the fixed frame.

[0019] The beneficial effect of adopting the above-mentioned further technical solution is that it provides a four-sided limit function to prevent deviation.

[0020] Furthermore, pneumatic silicone strips are installed in both the upper and lower sealing grooves of the pressure frame.

[0021] The beneficial effect of adopting the above-mentioned further technical solution is that by clamping the upper box and the pressure frame with a quick clamp, pressure is generated and applied to the gas rubber silicone strip. Since the gas rubber silicone strip has a coefficient of friction, the pressure applied to the gas rubber silicone strip can be converted into frictional force, thereby tightening the sealing plate.

[0022] Furthermore, a buffer plate is bonded to the bottom surface of the hard pressure plate body.

[0023] The beneficial effect of adopting the above-mentioned further technical solution is to provide a buffering effect when the rigid plate and the solar cell module come into contact.

[0024] Furthermore, both the sealing plate and the buffer plate are made of high-temperature resistant flexible material.

[0025] A soft pressing mechanism for a laminator replaces the sealing plate, the pressure plate frame, the hard pressure plate, and the compression spring as described above with a pressure frame angle buffer block and a rubber plate. The pressure frame angle buffer block is installed on the top of the pressure frame flange by the short-head bolts; the rubber plate is pressed between the upper box and the pressure frame.

[0026] By adopting the above technical solutions, the present invention produces the following beneficial effects:

[0027] It is easy to replace, meets the lamination process of single-glass and double-glass modules, effectively shortens the time for switching module types, reduces labor costs, and improves applicability. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] like Figure 1-2 As shown, this embodiment of the invention discloses a hard pressing mechanism for a laminator, including an upper box 1, a pressure frame 2, a quick clamp 3, a sealing plate 4, a pressure plate frame 5, a hard pressure plate 6, a pressure frame flange 7, and a compression spring 8. The upper box 1 and the pressure frame 2 at its bottom are connected by the quick clamp 3. The sealing plate 4 is pressed between the upper box 1 and the pressure frame 2. The sealing plate 4 has a through hole in the middle and is made of a high-temperature resistant flexible material. The pressure plate frame 5, the sealing plate 4, and the hard pressure plate 6 are arranged from top to bottom and connected together by a first bolt. The sealing plate 4, the pressure plate frame 5, and the hard pressure plate 6 divide the entire lamination chamber into an upper chamber and a lower chamber, retaining the characteristics of conventional sheet lamination. The pressure frame flange 7 is located on the inner side of the bottom of the pressure frame 2 and is connected by a second bolt 9. The compression spring 8 is vertically installed between the hard pressure plate 6 and the pressure frame flange 7. This invention achieves hard pressing, resulting in more uniform stress on the solar cell module, higher consistency in edge thickness after the solar cell module is finished, and higher yield in subsequent processes. At the same time, it eliminates the need to replace the adhesive sheet, saving a lot of adhesive sheet consumables and labor costs, reducing equipment downtime and improving equipment utilization.

[0035] Specifically, the sealing plate 4 has multiple round holes; the pressure plate frame 5 has multiple countersunk holes 51 corresponding to the positions of the round holes; the hard pressure plate 6 has multiple threaded blind holes 61 corresponding to the positions of the round holes; the first bolt is a countersunk bolt, which is threaded through the round hole and threaded blind hole 61, and the head of the countersunk bolt is located in the countersunk hole 51 to avoid the bolt head protruding from the pressure plate frame 5 and occupying space.

[0036] To further optimize the technical solution of the present invention, the bottom of the pressure plate frame 5 is provided with multiple arc-shaped sealing protrusions 52 to facilitate sealing with the sealing plate 4; the outer periphery of the pressure plate frame 5 is covered with a silicone edge strip 10 as a secondary seal and to protect the sealing plate 4 from damage, thereby extending its service life.

[0037] Specifically, it also includes a low-profile bolt 11, and a rigid pressure plate 6 including a fixed frame and a rigid pressure plate body that are distributed vertically and connected as one piece, with a threaded blind hole 61 opened on the fixed frame; a limit groove is opened at the bottom of the fixed frame, and the top of the compression spring 8 is located in the limit groove; the low-profile bolt 11 is screwed onto the pressure frame flange 7 and extends into the compression spring 8 to limit the position of the compression spring 8 and ensure that it plays its role.

[0038] To further optimize the technical solution of the present invention, multiple vertically intersecting support beams 12 are also included, each support beam 12 being connected to the top surface of the hard pressure plate body to improve the strength of the hard pressure plate body.

[0039] To further optimize the technical solution of the present invention, multiple rigid limiting strips 13 are fixed around the periphery of the fixed frame to limit movement around the perimeter and prevent displacement.

[0040] To further optimize the technical solution of the present invention, a gas rubber silicone strip 14 is installed in both the upper and lower sealing grooves of the pressure frame 2. In this way, the upper box 1 and the pressure frame 2 are clamped by the quick clamp 3, and pressure is applied to the gas rubber silicone strip 14. Since the gas rubber silicone strip 14 has a coefficient of friction, the pressure applied to the gas rubber silicone strip 14 can be converted into frictional force, thereby fastening the sealing plate 4.

[0041] To further optimize the technical solution of the present invention, a buffer plate 15 is bonded to the bottom plane of the rigid plate body. The buffer plate 15 is made of a high-temperature resistant flexible material to provide a buffering effect when the rigid plate 6 comes into contact with the solar cell module.

[0042] like Figure 3 , 4 As shown, this embodiment of the invention also discloses a soft pressing mechanism for a laminator, replacing the sealing plate 4, pressure plate frame 5, hard pressure plate 6, and compression spring 8 with a pressure frame angle buffer block 16 and a rubber sheet. The pressure frame angle buffer block 16 is installed on the top of the pressure frame flange 7 via low-head bolts 11; the rubber sheet is pressed between the upper box 1 and the pressure frame 2. This invention facilitates replacement, meets the lamination processes of single-glass and double-glass modules, effectively shortens the module panel switching time, reduces labor costs, and improves applicability.

[0043] Working principle of the invention:

[0044] During the lamination of the solar cell modules, the rigid pressure plate 6 moves towards the solar cell modules under the vacuum of the lower chamber until it presses the modules firmly. Simultaneously, compressed air enters the upper chamber through the air inlet, providing positive pressure and achieving a secondary pressurization function for the solar cell modules. Since the working surface of the rigid pressure plate 6 in contact with the solar cell modules is a single flat plate, it ensures that the entire plate completely adheres to the plane of the solar cell modules, guaranteeing uniform stress on all parts of the solar cell modules throughout the lamination process and maintaining consistent flatness. After lamination is completed, the upper chamber is depressurized through the air inlet, and the lower chamber is filled with atmosphere through the vacuum port on the heating plate (consistent with existing technology). The rigid pressure plate 6 returns to its original position under the traction of the compression spring 8, thus ensuring that the solar cell modules can smoothly proceed to the next process after lamination.

[0045] When sudden factors such as vacuum depressurization or sudden interruption of compressed air occur, the upper box 1 will open. At this time, the hard pressure plate 6 inside the cavity will open along with the upper box 1 under the action of the elastic force generated by the compression spring 8, so that the components can be repaired smoothly.

[0046] When laminated single-glass modules are required, the rigid pressing structure plate (sealing plate 4, pressing frame 5, rigid pressing plate 6) is transported out by tooling to the feeding table or discharging table for fixing. The pressing frame angle buffer block 16 is switched, and the glue plate is installed to realize the soft pressing function.

Similar or identical parts between embodiments can be referred to interchangeably.
