The present application will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present application more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art according to the specific circumstances.
In the description of the present specification, it should be understood that the terms "upper", "lower", and the like used in the embodiments of the present application are described in terms of the angles shown in the drawings, and should not be construed as limiting the embodiments of the present application. In the context of this document, it will also be understood that when an element is referred to as being "on" or "under" another element, it can be directly on the other element or be indirectly on the other element through intervening elements.
As shown in fig. 1 to 5, an embodiment of the present application provides a method for preparing a film, which includes the following steps:
s1, preparing a flat adhesive film.
The flat adhesive film can be obtained by the existing hot pressing mode and is generally formed by extrusion molding of a steel roller and a rubber roller.
And S2, forming more than two strip-shaped holes or strip-shaped grooves on the flat adhesive film to form the adhesive film with special lines.
It should be noted that in the prior art, a flat adhesive film is generally laminated on the battery pieces, and for stitch-welded battery pieces, part of the adjacent two battery pieces are in lamination welding connection, that is, part of the front surface of one battery piece and part of the back surface of the adjacent battery piece are in lamination welding connection, so that stitch-welded areas are formed at lamination welding positions. When the flat adhesive film is laminated on the back of the battery string, the adhesive film melts at high temperature and partially enters the gap between the two battery pieces in the stitch welding area, so that more height differences are generated between the adjacent two battery pieces at the stitch welding part due to the fusion of the adhesive film, and hidden cracks are generated.
Therefore, in this embodiment, after the flat adhesive film is formed, a bar-shaped groove or a bar-shaped hole is further processed on the flat adhesive film, and when the adhesive film is laid on the battery pieces, the bar-shaped groove or the bar-shaped hole is aligned with the stitch welding area between two adjacent battery pieces. In the lamination process, the adhesive film can be diffused in the strip-shaped groove or the strip-shaped hole after being melted, namely, the melted part of the adhesive film can be accommodated by the strip-shaped groove or the strip-shaped hole and can not be fused between two adjacent battery pieces in the stitch welding area, so that the expansion of the height difference between the battery pieces is avoided, and further, the hidden cracking phenomenon is avoided.
S3, detecting whether the distance between two adjacent strip-shaped holes or strip-shaped grooves accords with a set threshold value; if so, step S4 is entered.
Because the battery string is generally formed by stitch welding a plurality of battery pieces, namely, the battery string can be provided with a plurality of stitch welding areas, and the adhesive film is generally a complete adhesive film which can cover all the battery strings, more than two strip-shaped holes or strip-shaped grooves can be formed on the smooth adhesive film in order to prevent the adhesive film from entering between the battery pieces in any stitch welding area after being melted, so that the stitch welding area on each battery string can correspond to one strip-shaped groove or strip-shaped hole.
The positions of the stitch welding areas on each battery string are different due to the different sizes of the battery pieces and the battery strings, so that the positions of the strip-shaped holes or the strip-shaped grooves on the adhesive film can be designed according to the size specifications of the battery pieces and the battery strings to be processed. After the strip-shaped holes or the strip-shaped grooves are processed, the distance between two adjacent strip-shaped holes or strip-shaped grooves can be detected to judge whether the positions of the strip-shaped holes or the strip-shaped grooves meet the position requirement of the stitch welding area on the battery string.
And S4, taking the adhesive film with the special lines as a qualified product.
When the distance between two adjacent strip-shaped holes or strip-shaped grooves is detected to be in accordance with a set threshold value, the adhesive film can be put into assembly with a battery string and laminated. Wherein, the set threshold value can be 10 mm-15 mm. In this embodiment, the set threshold value is preferably 11mm, 12mm, 13mm, or 14mm. Of course, the threshold value may be another value, and specifically may be set according to the size specifications of the battery cell and the battery string.
Compared with the prior art, the adhesive film preparation method provided by the embodiment of the application solves the problem that the gap between the battery pieces is enlarged because the existing smooth adhesive film enters between two adjacent battery pieces in the stitch welding area after lamination and melting.
As a specific implementation, the scale 2 may be used to detect the distance between two adjacent strip-shaped holes 11 or strip-shaped grooves. Wherein, be provided with the position marking 23 more than two on the scale 2, the both sides of every position marking 23 all are provided with first error marking 24 and second error marking 25 respectively, form the detection zone between first error marking 24 and the second error marking 25, and the width of detection zone is greater than the width of bar hole 11 or bar groove.
The width of the detection area formed by the first error mark 24 and the second error mark 25 can measure whether the positions of the bar holes 11 or the bar grooves are qualified.
In detecting whether the distance between two adjacent strip-shaped holes 11 or strip-shaped grooves meets a set threshold, the following steps can be adopted to judge:
step S31, aligning the set detection area with the set bar hole 11 or bar groove.
Step S32, determining whether the edge of the set bar hole 11 or bar groove is located in the set detection area.
After the detection areas at the positions marked lines 23 on the scale are aligned with the bar holes 11 or the bar grooves, if the bar holes 11 or the bar grooves are in the corresponding detection areas, the adhesive film with special lines is qualified; if at least one bar hole 11 or bar groove is not located in the detection area at the corresponding position on the scale 2, the adhesive film with special lines is a defective product.
Wherein, because the width of the detection area is greater than the width of the bar hole 11 or the bar groove, the bar hole 11 or the bar groove can have a certain adjustment allowance in the detection area, and when each bar hole 11 or the bar groove is in the corresponding detection area and each bar hole 11 or each bar groove is not covered on the first error marking 24 or the second error marking 25, the adhesive film with special lines is qualified.
As a specific implementation, as shown in fig. 5, the scale 2 includes a first detection portion 21 and a second detection portion 22, and an end of the first detection portion 21 is rotatably connected to an end of the second detection portion 22.
Since the overall size of the adhesive film is generally longer and is generally greater than 2m, in order to facilitate the use of the scale, the first detecting portion 21 and the second detecting portion 22 which are rotatably connected may be provided, and the lengths of the first detecting portion 21 and the second detecting portion 22 may be greater than 1m, and in this embodiment, the lengths of the first detecting portion 21 and the second detecting portion 22 may be 1m.
When it is necessary to detect the strip-shaped hole 11 or the strip-shaped groove on the adhesive film, the first detecting portion 21 and the second detecting portion 22 may be unfolded by 180 ° so that the unfolded size of the scale 2 is 2m or more. When the detection is not required, the first detection portion 21 and the second detection portion 22 can be folded and combined to reduce the overall size of the scale 2, facilitating storage.
As a specific implementation manner, in order to facilitate the rotation connection of the first detection portion 21 and the second detection portion 22, one end of the first detection portion 21 is provided with a first shaft hole, one end of the second detection portion 22 is provided with a second shaft hole, and the first detection portion 21 and the second detection portion 22 are connected through the cooperation rotation of the first shaft hole, the second shaft hole and the pin shaft 26.
The strip-shaped holes 11 or the strip-shaped grooves may be formed by one-step molding in the process of molding the adhesive film by a hot-pressing method. Specifically, the raised stripes can be designed on the steel roller, and the strip-shaped holes 11 or the strip-shaped grooves can be formed in one step through the raised stripes when the adhesive film is extruded. However, due to the high temperature of the hot pressing method, the adhesive film can generate a certain deformation amount under the high temperature, so that the size of the strip-shaped groove or the strip-shaped hole in the molding process is unstable, and due to the difference between the sizes of the cell sheets with different sizes and the stitch welding areas of the cell strings, corresponding raised stripes are required to be designed on the steel roller, so that the manufacturing time and the manufacturing cost of the steel roller are greatly increased.
For this purpose, in a specific embodiment of the present application, when the strip-shaped holes 11 or the strip-shaped grooves are formed on the flat adhesive film 12, more than two strip-shaped holes 11 may be cut on the flat adhesive film by using a cutter. Wherein, the mode of cutter processing is cold pressing method, and the cutter can be controlled by automated equipment. The flat adhesive film 12 can be conveyed to a cutting station, after the strip-shaped holes 11 are cut, the adhesive film with special lines can be put into a station for assembling the battery strings for assembling, and after the assembling is completed, the adhesive film is input into a laminating machine for laminating, so that the photovoltaic module is formed.
In another specific embodiment, the strip-shaped holes 11 or the strip-shaped grooves can be formed on the flat adhesive film 12 by the following steps:
step S21, setting the laser emission frequency.
Step S22, more than two strip-shaped grooves are cut on the flat adhesive film 12 by laser.
Wherein, the depth of the strip-shaped groove formed on the adhesive film can be precisely controlled by setting the laser emission frequency. When the laser is used for processing the strip-shaped groove, the laser does not need to penetrate through the adhesive film, and the groove-shaped structure with the set depth can be formed on the adhesive film only.
It should be noted that, for processing the strip-shaped hole 11 on the adhesive film, the strip-shaped hole 11 needs to penetrate the adhesive film, and a larger deformation amount can be generated at the position of the strip-shaped hole 11 on the adhesive film, which is not beneficial to aligning the strip-shaped hole 11 with the stitch welding area on the battery string when the adhesive film is laid on the battery string.
Compared with the strip-shaped hole, the strip-shaped groove only has a certain depth on the adhesive film, and does not penetrate through the adhesive film, so that deformation of the adhesive film at the strip-shaped groove can be hardly generated, and the alignment of the strip-shaped groove and the position of the stitch welding area on the battery string is facilitated.
In addition, it should be noted that, the mode of processing the strip-shaped hole 11 by using the cutter or processing the strip-shaped groove by using the laser is to separately process the flat adhesive film 12, but not to process the flat adhesive film 12 after being laid on the battery piece in advance, otherwise, the risk of damaging the battery piece by using the cutter or the laser is easily caused, more importantly, each battery piece of the stitch welding battery piece is obliquely placed, the upper part of the formed battery string is not a plane, when the adhesive film is laid on the battery string, even supporting force is difficult to be provided for the adhesive film, and collapse of part of the position on the adhesive film is easily caused, which is unfavorable for processing the strip-shaped hole 11 or the strip-shaped groove.
Specifically, in a specific embodiment, the strip-shaped holes 11 or the strip-shaped grooves are provided in parallel in the length direction of the adhesive film, and the strip-shaped holes 11 or the strip-shaped grooves may be provided in plurality at intervals in the width direction of the adhesive film.
It can be appreciated that in a photovoltaic module, there may be a plurality of battery strings, each battery string may be laid parallel to each other, a certain distance is maintained between two adjacent battery strings, and the adhesive film with special lines may be laid on each battery string at the same time. Since the stitch bonding region is formed on the battery strings, the region between the respective battery strings may be laminated and packaged by the adhesive films on both sides of the battery strings, and thus, the interval between the bar holes 11 or the bar grooves in the width direction of the adhesive film may be not greater than the distance between the adjacent two battery strings.
In another specific embodiment, as shown in fig. 4, in order to facilitate the processing of the bar holes 11 and the bar grooves, the bar holes 11 or the bar grooves may be continuously extended in the width direction of the adhesive film.
The embodiment of the application also provides a glue film which can be manufactured by the glue film preparation method provided by any embodiment of the application. Wherein, the adhesive film 1 is provided with more than two strip-shaped holes 11 or strip-shaped grooves.
The above description is only of the preferred embodiments of the present application and is not intended to limit the present application, but various modifications and variations can be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
