Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of production and manufacturing of photovoltaic modules, and in particular to a fixing device and a cutting machine. BACKGROUND

[0002] In the production and manufacturing process of photovoltaic modules, it is usually necessary to go through multiple processes such as welding of cell pieces, application of adhesive film, lamination, inspection and lamination. In the adhesive film application process, it usually includes the steps of glass feeding and adhesive film application on the surface of the glass.

[0003] Currently, in the HJT module of the photovoltaic industry, the adhesive film needs to be precisely laid on the photovoltaic glass, and the precision requirement of the distance between the edge of the adhesive film and the edge of the glass is relatively high, and the adhesive film needs to be flat and cannot have a bulge phenomenon. After the adhesive film is applied on the glass, the adhesive film and the glass are relatively fixed through the static friction force between them, but when the adhesive film and the glass continue to move to the next process, the glass suddenly starts to move from static or suddenly changes from moving to stopping, under the action of inertia, the adhesive film will displace relative to the glass, causing the position deviation of the adhesive film and the glass, and further causing the edge position of the photovoltaic module to have bubbles due to lack of adhesive after the lamination process, resulting in degradation of the photovoltaic module and poor performance of the photovoltaic module.

DETAILED DESCRIPTION

[0039] In order to make the objects, technical solutions and advantages of the present application clearer, the present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be explained that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and embodiments.

[0040] It should be explained that the terms “first”, “second” and the like in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and do not have to be used to describe a specific order or sequence. It should be understood that the terms used in this way can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms “include” and “have” and any variations thereof are intended to cover non-exclusive inclusion, for example, a process, method, system, product or device including a series of steps or units does not have to be limited to the steps or units clearly listed, but can include other steps or units not clearly listed or inherent to these processes, methods, products or devices.

[0041] In the following, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments can be implemented in various different forms and should not be interpreted as being limited to the embodiments set forth herein.

[0042] As shown in FIG. 1, in a first aspect, the embodiments of the present application can provide a fixing device for fixing the adhesive film and the glass in a photovoltaic module, which can include: Figures 1-3 a body 1;

[0043] a fixing mechanism 2 arranged on the body 1;

[0044] The fixing mechanism 2 includes a mounting frame, and a smoothing assembly and a fixing assembly arranged on the mounting frame;

[0045] ​

[0046] The leveling component is used to level the adhesive film, and the fixing component fixes the adhesive film and glass by generating static electricity.

[0047] In this embodiment, after the adhesive film is laid on the glass, it is first smoothed by a leveling component, and then the adhesive film is fixed to the glass without damage by an electrostatic generation by a fixing component. Furthermore, the adhesive film and the glass have a strong adhesion, so that the adhesive film will not be displaced relative to the glass during subsequent high-speed movement or under the action of inertia, thereby reducing the problem of positional deviation between the adhesive film and the glass.

[0048] It should be noted that in traditional technology, the adhesive film is typically fixed to the glass using a spot-heating method. This involves a heating head using a heating element to heat the film and fix it to the glass. However, with this method, excessively high welding temperatures can easily burn through the adhesive film, leading to air bubbles after lamination. Conversely, excessively low welding temperatures result in long welding times, affecting production line speed and causing the film to shift during transport due to poor adhesion. The fixing device used in this embodiment of the application, however, provides high fixing efficiency, reduces impact on production line speed, and fixes the film to the glass without damage, thus preventing irreversible burns that could cause air bubbles after lamination. Furthermore, it reduces the likelihood of yellowing of the film after lamination.

[0049] In an optional embodiment, the mounting bracket includes a first mounting rod 21 and a second mounting rod 22; a first mounting block 211 is slidably disposed on the first mounting rod 21; a second mounting block 221 is slidably disposed on the second mounting rod 22; a first mounting plate 212 is movably connected to the first mounting block 211, and a second mounting plate 222 is movably connected to the second mounting block 221; the leveling assembly includes a smoothing part; the smoothing part includes a first connecting plate 23, a second connecting plate 24, and a smoothing plate 25, the first connecting plate 23 being rotatably connected to the first mounting plate 212, and the second connecting plate 24 being rotatably connected to the second mounting plate 222; one end of the smoothing plate 25 is connected to the first connecting plate 23, and the other end is connected to the second connecting plate 24; the side of the smoothing plate 25 facing the adhesive film has a brush 251; wherein, the brush 251 is used to smooth the adhesive film.

[0052] In the embodiment, the height of the blowing pipe 28 can be adjusted by adjusting the height of the first mounting block 211 and the second mounting block 221; since the first fixed plate 26 is rotatably arranged on the first mounting plate 212 and the second fixed plate 27 is rotatably arranged on the second mounting plate 222, the angle of the blowing pipe 28, i.e. the angle of the exhaust holes on the blowing pipe 28, can be adjusted according to actual needs, so as to blow the adhesive film.

[0053] In an optional embodiment, the exhaust holes comprise a plurality of spaced apart exhaust holes 281; wherein the plurality of exhaust holes 281 are uniformly arranged.

[0054] In the embodiment, the uniformly spaced exhaust holes 281 can achieve the effect of uniformly blowing the adhesive film, and the smoothing effect is better; in addition, the air flow of the exhaust holes 281 can be adjusted according to actual conditions.

[0058] In the embodiment, the first adjusting hole 291 and the second adjusting hole 301 can be in the shape of a strip, and mainly adjust the position of the fixer 31 along the transportation direction of the glue film and the glass.

[0059] In an optional embodiment, the number of the smoothing plates 25 is several, and the several smoothing plates 25 are arranged in parallel with each other.

After the adhesive film is precisely laid on the glass, the conveying mechanism 11 conveys the adhesive film and the glass from between the first installation rod 21 and the second installation rod 22.
