Description

Technical Field

[0001] The present invention relates to the technical field of equipment for photovoltaic module production lines, and particularly to an EVA film laying device. Background Art

[0002] With the increasingly widespread application of solar power generation, the demand for photovoltaic modules is increasing. In order to improve the production capacity and equipment cost of solar photovoltaic modules, various new technologies have emerged continuously. EVA laying is an important process in the automatic production line of photovoltaic modules, and it has a very obvious impact on the production capacity of the production line.

[0003] The patent application document with the publication number CN113247624A discloses an automatic EVA laying device for photovoltaic modules. The automatic EVA laying device for photovoltaic modules discloses a laying table, an EVA feeding device arranged on both sides of the laying table, an EVA spreading device arranged above the laying table, and an EVA translation device. The EVA feeding device is used to convey the EVA material to the EVA spreading device. The EVA spreading device includes an automatic cutting mechanism for cutting the EVA material and an EVA spreading mechanism. The EVA translation device is used to adsorb and transport the cut EVA material on the laying table to the accompanying tooling plate.

[0004] When the above patent application document is used, it can automatically cut the EVA into small strip structures and transport them to the accompanying tooling plate. However, EVA films not only have small strips but also have small blocks. And with the increasingly widespread application of photovoltaic modules, there are more and more styles on the accompanying tooling plate. Usually, small strips and small materials need to be laid at the same time. However, the above patent application document can only lay small strips. When small materials and small strips need to be laid at the same time, another laying device needs to be set up or the small materials need to be laid manually, which increases the cost and it is easy for manual workers to miss placing. Summary of the Invention

[0005] The present invention provides an EVA film laying device to solve the technical problems of high cost and easy missing placement by manual workers in the existing EVA film laying.

[0006] To solve the above problems, an EVA film laying device provided by the present invention adopts the following technical solutions:

The strip-shaped film laying module and the block-shaped film laying module are respectively arranged on the left and right sides of the conveying mechanism and are arranged facing each other in the left-right direction. The strip-shaped film laying module includes a wide film feeding mechanism, a strip-shaped film cutting mechanism, and a strip-shaped film laying mechanism slidably assembled on the frame in the left-right direction. The wide film feeding mechanism is used for supplying wide films, the strip-shaped film cutting mechanism is used for cutting the wide films into strip-shaped films, and the strip-shaped film laying mechanism includes strip-shaped film suction cups for adsorbing strip-shaped films and placing the strip-shaped films on the photovoltaic panels when the strip-shaped film laying mechanism moves left and right. The block-shaped film laying module includes a strip-shaped film feeding and cutting mechanism and a block-shaped film laying mechanism slidably assembled on the frame in the left-right direction. The strip-shaped film feeding and cutting mechanism is used for conveying the rolled strip-shaped films to the right and cutting them into block-shaped films. The block-shaped film laying mechanism includes block-shaped film suction cups for adsorbing block-shaped films and placing the strip-shaped films on the photovoltaic panels when the block-shaped film laying mechanism moves left and right.

[0008] The beneficial effects are as follows: When the EVA film laying device of the present invention is in use, first start the conveying mechanism to convey the raw materials of the EVA to be laid into the frame, and then start the strip-shaped film laying mechanism according to requirements to suck and lay the cut small strips at the set positions on the conveying mechanism; at the same time, start the block-shaped film laying mechanism to suck and lay the cut small materials at the set positions on the conveying mechanism. When the EVA film laying device of the present invention is in use, according to different requirements, it can simultaneously realize the laying of EVA films in different styles such as "small strip, small strip, small strip", "small strip, small material, small strip", and "small material, small strip, small material".

Detailed implementation manners

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Those skilled in the art should know that the embodiments described below are part of the embodiments of the present disclosure, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present invention.

[0041] The number of any element in the drawings is for illustration rather than limitation, and any naming is only for distinction and does not have any limiting meaning.

[0042] Next, with reference to several representative embodiments of the present invention, the principles and spirits of the present invention will be elaborated in detail.

[0043] Embodiment 1 of an EVA film laying device provided by the present invention:

[0044] As Figures 1 to 11 shown, an EVA film laying device of the present invention includes a frame 1 and a conveying mechanism 2 provided on the frame 1 for conveying photovoltaic panels in the front-rear direction. The conveying mechanism 2 is provided in the middle of the frame 1 and conveys photovoltaic panels in the front-rear direction.

[0045] As Figure 1 and Figure 2 shown, a strip film laying module, a block film laying module, a block film track 3 extending in the left-right direction, and a strip film track 4 extending in the left-right direction are provided in the frame 1. The strip film laying module and the block film laying module are respectively arranged on the left and right sides of the conveying mechanism 2 and are arranged opposite to each other in the left-right direction. As Figure 1 shown, there are two block film tracks 3 and two strip film tracks 4, and they are respectively provided on the inner sides of the front and rear side walls of the frame 1. The block film track 3 is provided above the strip film track 4.

[0046] The strip film laying module is provided on the right side of the conveying mechanism 2 and includes a wide film feeding mechanism 5, a heavy hammer induction type tensioning mechanism 6, a strip film punching mechanism 7, a strip film feeding mechanism 8, a strip film cutting mechanism 9, a strip film distributing mechanism 10, and a strip film laying mechanism 11.

[0047] As Figure 1 and Figure 4As shown in the figure, the strip-shaped film feeding mechanism 5 is arranged at the right end of the frame 1. The strip-shaped film feeding mechanism 5 includes a block-shaped film raw material placing table 14, a welding part 15, a block-shaped film conveying power motor 16, and two transmission shafts arranged at intervals in the front-rear direction. During use, first place the EVA raw material on the block-shaped film raw material placing table 14 and push it to the position corresponding to the small strip conveying power transmission shaft. Then, clamp the EVA raw material between the two transmission shafts. Finally, start the block-shaped film conveying power motor 16 to drive the transmission shafts to rotate, so as to make the EVA raw material rotate and convey the EVA raw material to the left.

[0048] The welding part 15 is arranged above the transmission shaft, and the EVA raw material is conveyed to the left and passes through the welding part 15. The welding part 15 is a prior art, and its specific structure will not be described in detail here. The welding part 15 is used to weld the end of the used EVA raw material to the initial end of the newly loaded EVA raw material to improve the continuity of EVA raw material feeding.

[0049] As Figure 4 shown in the figure, the heavy hammer induction type tensioning mechanism 6 is arranged on the left side of the strip-shaped film feeding mechanism 5, and the EVA raw material passes through the heavy hammer induction type tensioning mechanism 6 and is conveyed to the left. The heavy hammer induction type tensioning mechanism 6 is a prior art, and its specific structure will not be described in detail here. The heavy hammer induction type tensioning mechanism 6 is used to tension the EVA raw material to improve the stability when the EVA raw material is conveyed to the left.

[0050] As Figure 5 shown in the figure, the strip-shaped film punching mechanism 7 is arranged on the left side of the heavy hammer induction type tensioning mechanism 6 to perform punching operations on the EVA film conveyed by the heavy hammer induction type tensioning mechanism 6. The strip-shaped film punching mechanism 7 is a prior art, and its specific structure will not be described in detail here. A waste material recovery pipe 17 is also connected below each punching station of the strip-shaped film punching mechanism 7.

[0051] As Figure 3 shown in the figure, the strip-shaped film feeding mechanism 8 is arranged on the left side of the strip-shaped film punching mechanism 7. The strip-shaped film feeding mechanism 8 includes a roller lifting cylinder, a lifting roller 18, a rotating roller 19, and a feeding motor. One end of the lifting roller 18 is connected to the telescopic end of the roller lifting cylinder. The rotating roller 19 is arranged at intervals in the up-down direction below the lifting roller 18. The output shaft of the feeding motor is coaxially fixed to the rotating roller 19. Striped deep grooves are provided on both the lifting roller 18 and the rotating roller 19. The deep grooves extend from the middle to the front and rear sides and are symmetrically arranged. During use, the lifting roller 18 descends under the drive of the roller lifting cylinder, so that the rotating roller 19 and the lifting roller 18 can clamp the EVA film. The feeding motor drives the rotating roller 19 to rotate to convey the EVA film to the left. At the same time, the striped deep grooves are provided so that when the EVA film is conveyed, the striped deep grooves can form opposite tensions on the EVA film in the front and rear directions, thereby ensuring the stability of the EVA film during conveyance and preventing the EVA film from bending.

[0052] As shown Figure 6 in FIG. 3, the strip film cutting mechanism 9 is disposed on the left side of the strip film feeding mechanism 8. The strip film cutting mechanism 9 includes a mounting plate 20, a plurality of cutting cylinders 21 disposed on the mounting plate 20, a cutting knife, and a strip film waiting-to-be-taken plate 22. The mounting plate 20 is fixedly mounted in the frame 1. There are two cutting cylinders 21, and both cutting cylinders 21 are fixed on the mounting plate 20 and the telescopic ends of the cutting cylinders 21 extend vertically downward. The cutting knife is connected to the telescopic ends of the respective cutting cylinders 21 and the cutting edge faces downward. The cutting knife is correspondingly arranged with the strip film waiting-to-be-taken plate 22 so that the cut small strips are all placed on the strip film waiting-to-be-taken plate 22.

There are three placing stations on the strip film placing plate 23. The distributing suction cup 27 is used to suck and place the small strips on the strip film waiting-to-be-taken plate 22 on the corresponding placing stations.

[0054] As shown Figure 9 in FIG. 6, the strip film laying mechanism 11 is disposed on the left side of the strip film distributing mechanism 10.

The strip film laying track 29 is slidably assembled on the strip film track 4 in the left-right direction.

[0055] The three groups of strip film suction cups 32 are correspondingly arranged with the three placing stations one by one, and the three groups of strip film suction cups 32 are controlled to operate independently, so that the strip film laying mechanism 11 can suck different numbers of small strips at different stations and place them at the conveying mechanism 2.

[0056] The block film laying module is disposed on the left side of the conveying mechanism 2, and the block film laying module includes a strip film feeding and cutting mechanism 12 and a block film laying mechanism 13

[0058] There are two small material placement plates, which are the first placement plate 36 and the second placement plate 37 respectively. The first placement plate 36 and the second placement plate 37 can reciprocate and alternate in the left-right direction. Specifically, as Figure 10 shown, the strip-shaped film feeding and cutting mechanism 12 further includes a first placement track 38, a second placement track 39, a carrier plate 40 slidably assembled on the second placement track 39, and a carrier cylinder 41 connected to the carrier plate 40. The second placement track 39 is located below the first placement track 38; the first placement plate 36 is slidably assembled on the first placement track 38, the second placement plate 37 is arranged at intervals in the up-down direction above the carrier plate 40, and the second placement plate 37 is connected to the telescopic end of the carrier cylinder 41; and when the carrier cylinder 41 is shortened to the shortest position, the second placement plate 37 is located below the first placement plate 36. There are three block-shaped film waiting-to-be-taken plates 42 on both the first placement plate 36 and the second placement plate 37.

[0059] As Figure 11 shown, the block-shaped film laying mechanism 13 is arranged on the right side of the strip-shaped film feeding and cutting mechanism 12. The block-shaped film laying mechanism 13 includes a block-shaped film laying track 43 extending in the front-rear direction, three block-shaped film lifting tracks 44 slidably assembled on the block-shaped film laying track 43, three block-shaped film suction cylinders 45 respectively slidably assembled on the three block-shaped film lifting tracks 44, and three block-shaped film suction cups 46 respectively installed at the telescopic ends of the three block-shaped film suction cylinders 45.

[0060] As Figure 1 and Figure 2 shown, the block-shaped film laying track 43 is slidably assembled on the block-shaped film track 3 in the left-right direction.

[0061] When the EVA film laying device of the present invention is in use, first start the conveying mechanism 2 to convey the raw material to be laid with EVA into the frame 1, and then start the strip-shaped film laying mechanism 11 according to the demand to suck and lay the cut small strips at the set positions on the conveying mechanism 2; at the same time, start the block-shaped film laying mechanism 13 to suck and lay the cut small materials at the set positions on the conveying mechanism 2.

[0062] When the EVA film laying device of the present invention is in use, according to different requirements, it can simultaneously achieve the laying of EVA films in different styles such as "strip, strip, strip", "strip, small piece, strip", and "small piece, strip, small piece". At the same time, it integrates the feeding, cutting, and laying of strips and the feeding, cutting, and laying of small pieces, improving production efficiency, reducing the occupied space, and reducing the manual labor, thereby reducing the cost of EVA film laying. At the same time, the mechanical automatic laying avoids the occurrence of accidents such as easy omission during manual laying.
