For example, CN114834138B discloses a laminating mechanism. The inside of the laminating cavity is divided into an upper chamber and a lower chamber by a silica gel pad. The shape change of the silica gel pad is realized by the change of the air pressure and vacuum in the upper chamber and the lower chamber (the air pressure of the upper chamber is controlled by the first air suction and charging assembly, and the air pressure of the lower chamber is controlled by the second air suction and charging assembly), so as to apply pressure to the solar cell module.

[0003] However, the existing technology has the following problems: 1) the flatness of the solar cell module laminated by the soft pressing form is not high, and the edge thickness is uneven; 2) affected by the supply of vacuum and compressed air, once sudden factors such as vacuum pressure relief and sudden air supply interruption occur, the laminating process cannot continue, the silica gel pad cannot be effectively separated from the solar cell module after the cover is opened, and the module cannot be repaired in the first time, which delays the production progress and efficiency of the enterprise and increases the secondary maintenance cost (materials, labor, etc.) of the enterprise; 3) it does not have the switching function of soft pressing form and hard pressing form, that is, the existing structure is not universal, it is not convenient to disassemble, replace and assemble, and the applicability is poor.

Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the protection scope of the present application.

[0034] As shown in the drawings, Figures 1-2 The embodiment of the present application discloses a hard pressing mechanism of laminating machine, which comprises an upper box 1, a pressing frame 2, a quick clamp 3, a sealing plate 4, a pressing plate frame 5, a hard pressing plate 6, a pressing frame flange 7 and a compression spring 8. The upper box 1 and the pressing frame 2 at the bottom thereof are connected through the quick clamp 3. The sealing plate 4 is pressed between the upper box 1 and the pressing frame 2. The sealing plate 4 has a through hole in the middle part thereof. The sealing plate 4 is made of high-temperature-resistant flexible material. The pressing plate frame 5, the sealing plate 4 and the hard pressing plate 6 are arranged from top to bottom and connected together through first bolts. The sealing plate 4, the pressing plate frame 5 and the hard pressing plate 6 divide the whole laminating chamber into two chambers, i.e. an upper chamber and a lower chamber, and retain the characteristics of conventional rubber plate laminating. The pressing frame flange 7 is located at the inner side of the bottom of the pressing frame 2 and is connected through a second bolt 9. The compression spring 8 is vertically installed between the hard pressing plate 6 and the pressing frame flange 7. The present application realizes hard pressing, the stress of the solar cell module is more uniform, the consistency of the thickness of the rear edge of the finished solar cell module is higher, the finished product rate of the subsequent link is higher, and meanwhile, the rubber plate does not need to be replaced, a large amount of rubber plate consumables and labor cost are saved, the equipment reduces downtime, and the utilization rate of the equipment is improved.

[0035] Specifically, the sealing plate 4 has a plurality of round holes; the pressing plate frame 5 has a plurality of countersunk holes 51 corresponding to the positions of the round holes; and the hard pressing plate 6 has a plurality of threaded blind holes 61 corresponding to the positions of the round holes. The first bolts are countersunk bolts. The countersunk bolts are screwed into the threaded blind holes 61 through the round holes and the heads of the countersunk bolts are located in the countersunk holes 51 so as to avoid the heads of the bolts protruding from the pressing plate frame 5 and occupying space.

[0036] In order to further optimize the technical scheme of the present application, the bottom of the pressing plate frame 5 is provided with a plurality of arc-shaped sealing bosses 52 for facilitating sealing with the sealing plate 4. The pressing plate frame 5 is wrapped with a silica gel edge strip 10 as secondary sealing and protection of the sealing plate 4 from damage, thereby prolonging the service life thereof.

[0037] Specifically, the hard pressing plate 6 comprises a fixed frame and a hard pressing plate body which are arranged in a top-down manner and connected into one body, and the threaded blind holes 61 are formed in the fixed frame. A limiting groove is formed in the bottom of the fixed frame, and the top end of the compression spring 8 is located in the limiting groove. The short head bolt 11 is screwed on the pressing frame flange 7 and extends into the compression spring 8 to limit the position of the compression spring 8 and ensure that the compression spring 8 functions.

[0038] In order to further optimize the technical scheme of the present application, a plurality of support beams 12 are arranged perpendicularly and cross each other, each of which is connected with the top surface of the hard pressing plate body, so as to improve the strength of the hard pressing plate body.

[0039] In order to further optimize the technical scheme of the present application, a plurality of hard limiting strips 13 are fixed on the periphery of the fixed frame, so as to limit the displacement.

[0040] In order to further optimize the technical scheme of the present application, a plurality of air silicone rubber strips 14 are installed in the upper sealing groove and the lower sealing groove of the pressing frame 2. When the upper box 1 and the pressing frame 2 are clamped by the quick clamp 3, the air silicone rubber strips 14 are pressed, and the pressure is converted into friction by the friction coefficient of the air silicone rubber strips 14, so as to fasten the sealing plate 4.

[0041] In order to further optimize the technical scheme of the present application, a buffer plate 15 is bonded to the bottom surface of the hard pressing plate body, which is made of flexible material with high temperature resistance, so as to provide a buffer effect when the hard pressing plate 6 contacts the solar cell assembly.

[0042] As shown in Figure 3 , 4 The present application also discloses a soft pressing mechanism of a laminating machine, in which the sealing plate 4, the pressing plate frame 5, the hard pressing plate 6 and the compression spring 8 are replaced by a pressing frame angle buffer block 16 and a rubber plate. The pressing frame angle buffer block 16 is installed on the top of the pressing frame flange 7 by means of a short head bolt 11. The rubber plate is pressed between the upper box 1 and the pressing frame 2. The present application is convenient to replace, satisfies the laminating process of single glass assembly and double glass assembly, effectively shortens the time for switching the assembly plate type, reduces the labor cost, and improves the applicability.

[0043] Working principle of the present application:

[0044] When the solar cell assembly is laminated, the hard pressing plate 6 moves towards the solar cell assembly under the action of the vacuum in the lower chamber until the solar cell assembly is pressed tightly. At the same time, the compressed air enters the upper chamber through the air inlet to provide positive pressure, so as to realize the secondary pressing function of the solar cell assembly. Since the working surface of the hard pressing plate 6 in contact with the solar cell assembly is a whole flat plate, the whole plate can be completely attached to the plane of the solar cell assembly, so as to ensure that the solar cell assembly is uniformly stressed in the whole laminating process and always maintains consistent flatness. When the laminating 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 (which is consistent with the prior art). The hard pressing plate 6 returns to the original position under the traction of the compression spring 8, so as to ensure that the solar cell assembly smoothly enters the next process after being laminated.

[0045] When the sudden factors such as vacuum pressure relief, compressed air suddenly off and the like occur, the upper box 1 performs the uncovering action, at this time the hard pressing plate 6 in the cavity is under the action of the elastic force generated by the compression spring 8, and performs the uncovering action together with the upper box 1, at this time the assembly can be smoothly repaired.

[0046] When the single glass assembly needs to be laminated, the hard pressing structure plate (the sealing plate 4, the pressing plate frame 5, the hard pressing plate 6) is transported out by the tool to the feeding table or the discharging table and fixed, the pressing frame angle buffer block 16 is switched, and the rubber plate is installed to realize the soft pressing function.

[0047] The various embodiments in the specification are described in a progressive manner, and each embodiment focuses on the difference from other embodiments, and the same or similar parts between various embodiments can be referred to each other. For the device disclosed by the embodiments, since it corresponds to the method disclosed by the embodiments, the description is relatively simple, and the related parts can be referred to the method part.

[0048] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present application. Various modifications to the embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application. Therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
