Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic component lamination, in particular to a solar photovoltaic component laminating machine. Background Art

[0002] Photovoltaic modules are devices used to convert light energy into electrical energy. They have a multi-layer structure, including a window layer, an absorber layer, and a back electrode layer. During the production of photovoltaic modules, a laminator is used to laminate the multi-layered modules at a specific temperature. This lamination process firmly bonds the various layers of the module together, improving its structural stability and weather resistance.

[0003] The Chinese invention patent with authorization publication number "CN113895131B," specifically for a "photovoltaic module lamination device," states in its specification and detailed implementation method that "an embodiment of the present invention utilizes the temperature and time matching characteristics of the lamination process and the electrical injection process to integrate the power supply assembly into the lower pressing assembly of the lamination device, thereby achieving simultaneous lamination and electrical injection processes."

[0004] Although it saves space and heating components, reduces production costs, and also improves the processing efficiency of photovoltaic modules, it does not take into account the dust prevention work of photovoltaic modules during lamination. Dust and impurities are easily attached between the layers of materials of the photovoltaic modules, resulting in poor circuit connection of the laminated photovoltaic modules, reducing the quality of the finished product and affecting the subsequent use. In addition, the downward pressure component is inserted into the support component. Although it can ensure accurate lamination, it reduces the loading and unloading efficiency of the photovoltaic modules, resulting in a decrease in the overall lamination efficiency.

[0005] In view of the above-mentioned shortcomings of the prior art, the utility model provides a solar photovoltaic module laminating machine, which can effectively solve the problems of poor product quality and low lamination efficiency in the prior art.

[0006] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0007] The utility model provides a solar photovoltaic module laminating machine, comprising two machine bases arranged in parallel and a plurality of rotating rollers rotatably installed between the two machine bases, a laminating seat is commonly installed on the top ends of the two machine bases, a laminating cavity is penetrated at both ends of the laminating seat, a hot air blower whose output end is connected to the laminating cavity is installed on the top end of the laminating seat, a sealing component comprises a rotating column rotatably installed at the two cavity openings of the laminating cavity, a plurality of closed baffles are installed on the outer column wall of the rotating column, the two opposite closed baffles are rotated to a unified plane, and are completely blocked at the cavity openings of the corresponding laminating cavities, a laminating transmission component comprises a laminating cover which is telescopically slidably installed in the laminating cavity, and also comprises an extrusion plate which moves synchronously with the laminating cover and is telescopically slidably installed on the cavity wall of the laminating cavity.

[0008] Furthermore, a motor is installed on the outer wall of one of the machine bases, a first sprocket is installed on the output end of the motor, a second sprocket connected to the first sprocket is installed on the same end of several rotating rollers, two bases are commonly installed at the bottom ends of the two machine bases, and a closed cylinder is also installed between the two machine bases, and a closed bottom plate attached to the bottom of several rotating rollers is installed on the output end of the closed cylinder.

[0009] Furthermore, notches are provided at both cavity openings of the lamination cavity, and the four rotating columns are rotatably installed on the upper cavity top and lower cavity bottom corresponding to the notches, and sliding grooves and receiving grooves are provided on the two opposite inner cavity walls of the lamination cavity.

[0010] Furthermore, the lamination transmission assembly also includes a lifting cylinder fixedly installed on the top of the lamination seat, the output end of the lifting cylinder extends into the lamination cavity, and a lifting rod is installed between the lamination cover.

[0011] Furthermore, L-shaped racks are installed on both sides of the lifting rod and are slidably installed in corresponding slide grooves. The two L-shaped racks are meshed with a first gear on the side away from each other, and the two first gears are meshed with a second gear below each other.

[0013] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

In order to prevent dust from entering the lamination chamber at the inlet and outlet of photovoltaic modules, multiple sealing baffles are set at the two cavity openings of the lamination chamber. The two rotating sealing baffles can seal the lamination chamber without affecting the inlet and outlet of photovoltaic modules. In conjunction with the sealing of the sealing bottom plate, it ensures that the photovoltaic modules in the lamination chamber are laminated in a closed and dust-free environment, thereby improving product quality.

[0015] 2. A lamination cover that can be lifted and slid is set in the lamination chamber. When the lamination cover is lifted and lowered, the transmission structure drives the two extrusion plates set on both sides of the photovoltaic module to move in an extension and contraction manner, so that the extrusion plates can be placed in the center and aligned with the lamination cover above.

[0024] The present invention will be further described below with reference to the embodiments. Example 1

The lamination transmission assembly includes a lamination cover 32 that is telescopically and slidably installed in the lamination cavity 21. The lamination cover 32 is a four-sided pyramid structure with a large bottom opening and a small top opening, which is convenient for adjusting the position of the photovoltaic module with a position offset. It also includes an extrusion plate 37 that moves synchronously with the lamination cover 32 and is telescopically and slidably installed on the inner wall of the lamination cavity 21. Example 2

[0026] Reference Figure 1-5, which is the second embodiment of the present invention, which is different from the first embodiment in that: a motor 12 is installed on the outer wall of one of the machine bases 1, and a first sprocket is installed at the output end of the motor 12, and a second sprocket connected to the first sprocket is installed at the same end of the plurality of rotating rollers 11. Two bases 13 are installed together at the bottom ends of the two machine bases 1, and a closed air cylinder 14 is installed between the two machine bases 1. The output end of the closed air cylinder 14 is installed with a closed bottom plate 15 attached to the bottom of the plurality of rotating rollers 11. The closed bottom plate 15 can make the laminating chamber 21 completely closed, and cooperate with the hot air blower 4 to improve the laminating effect. Notches 22 are provided at the two cavity openings of the laminating chamber 21, and four rotating columns 23 are rotatably installed at the upper cavity top and lower cavity bottom corresponding to the notches 22 respectively. A slide groove 25 and a storage groove 26 are provided on the two opposite inner cavity walls of the laminating chamber 21. The laminating transmission assembly also includes a lifting cylinder 3 fixedly installed on the top of the laminating seat 2, and the output end of the lifting cylinder 3 extends through the laminating chamber 21, and A lifting rod 31 is installed between the laminate cover 32, and L-shaped racks 33 are installed on both sides of the lifting rod 31 for lifting and sliding in the corresponding slide groove 25.

[0027] The remaining structures are the same as those of Example 1.

[0028] The working principle of this utility model is as follows:

[0029] First, the laid photovoltaic modules are placed on the rotating rollers 11, and the motor 12 is started to drive the rotating rollers 11 to rotate, thereby feeding the photovoltaic modules into the lamination chamber 21. When the photovoltaic modules reach the opening of the lamination chamber 21, they touch the corresponding two closed baffles 24, thereby driving the rotating column 23 to rotate. When the photovoltaic modules are completely in the lamination chamber 21, the other closed baffle 24 on the outer wall of the two rotating columns 23 will also rotate to block the opening of the lamination chamber 21, thereby blocking the opening of the lamination chamber 21, making the interior of the lamination chamber 21 closed, preventing dust from entering, and improving the lamination quality of the photovoltaic modules.

[0030] Secondly, when the photovoltaic module enters under the laminating cover 32, the lifting cylinder 3 is started, and the laminating cover 32 is driven down through the lifting rod 31, and the two L-shaped racks 33 are driven down simultaneously, thereby driving the first gear 34 to engage and rotate, thereby driving the second gear 35 to engage and rotate, and also driving the telescopic rack 36 to slide in the corresponding transmission cavity, thereby pushing the corresponding extrusion plate 37 to extend into the laminating cavity 21 and squeeze and contact the photovoltaic module, so that the photovoltaic module is pushed to the center position, which is convenient for the position opposite to the laminating cover 32. Finally, the laminating cover 32 is completely stuck on the photovoltaic module, and the photovoltaic module is laminated by applying pressure;

[0031] Finally, while the lamination hood 32 is applying pressure to perform the lamination operation, the sealing cylinder 14 is started to drive the sealing bottom plate 15 to rise in height, thereby blocking the bottom of several rotating rollers 11, so that the lamination chamber 21 is completely closed, and then the hot air blower 4 is started to deliver hot air flow into the lamination chamber 21, increasing the stability of the lamination chamber 21, thereby improving the lamination efficiency.

[0032] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it.
