It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application.

[0028] In addition, if there are terms such as "first" and "second", these terms are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one such feature.

[0032] In recent years, with the in-depth development of industry, the degree of human development's dependence on energy has gradually increased. Due to the non-renewability of fossil energy and a series of environmental problems brought about by greenhouse gas emissions, all sectors of society have turned their attention to solar energy, which is efficient, sustainable and pollution-free. The degree of exploration and utilization of solar energy plays a crucial role in the structural adjustment of future energy development. At the same time, under the influence of the trend of the carbon neutral era, the photovoltaic industry is expected to lead the rapid development of renewable energy.

[0033] With the continuous development and improvement of the photovoltaic industry, in order to enhance the industry competitiveness, efficient and low-cost manufacturing methods have become an effective means for enterprises to improve their competitiveness. During the process of efficiency improvement and cost reduction, various tests will be carried out to verify improvements or changes; various tests will be conducted on the component test line, and these tests have different patterns, different main materials, etc., and in most cases, large-scale production will not be carried out for each test, which makes the equipment adjustment relatively frequent. Therefore, when making some small batches of components, manually opening holes in the backsheet and the encapsulant film is actually faster and more convenient than adjusting the punching position of the cutting machine.

[0034] Currently, manually opening holes in the backsheet and the encapsulant film mainly relies on a lamination template to determine the position, and then a small knife is used to cut circular or square holes. This manual hole-opening method is slow, prone to hole position deviation, and irregular hole openings will occur. At the same time, there is a risk of scratching the lower layer material during operation. The main current solution to this problem is to use a cutting machine to open holes while cutting the encapsulant film or the backsheet, but this method is cumbersome to debug and wastes materials, and is not suitable for the manufacture of experimental samples. The existing hole-opening structures have the following disadvantages:

[0035] 1. The switching of the existing machine hole-opening equipment is cumbersome, and it takes a long time for small-batch use;

[0036] 2. When manually using a utility knife to cut and open holes, the hole sizes will be inconsistent, consuming manpower and time.

[0037] 3. The existing hole openers use hard links to open holes, and in this case, it is impossible to open holes in the backsheet, which is a material that is far from the edge and cannot be folded.

[0038] To solve the above technical problems, the present application provides a backsheet hole opener, which avoids frequent equipment switching, reduces the manpower for hole opening, and at the same time uses magnetic connection to replace the conventional hard connection, and can open holes in the backsheet, which is a material that is far from the edge and cannot be folded.

[0039] As Figures 1 to 3 shown, the backsheet hole opener includes a first hole-opening structure 100 and a second hole-opening structure 200. The first hole-opening structure 100 includes a first base 110 and a hole-opening knife 120 connected to each other; the second hole-opening structure 200 includes a second base 210, and a knife groove 220 is provided on the second base 210. The first base 110 and the second base 210 can cooperate with each other to clamp the backsheet, and the hole-opening knife 120 is configured to move in the direction close to the second base 210 to pass through the backsheet and extend into the knife groove 220.

[0040] The above-mentioned backplane puncher clamps the backplane through the cooperation of the first base 110 of the first punching structure 100 and the second base 210 of the second punching structure 200. Then, the punching knife 120 is moved towards the second base 210, so that the punching knife 120 penetrates through the backplane and extends into the knife groove 220, thereby punching holes in the backplane. Moreover, the punching knife 120 finally extends into the knife groove 220, preventing the punching knife 120 from damaging the underlying material. The backplane puncher provided by this application speeds up the punching speed. When the punching knife 120 penetrates through the backplane, there will be no phenomenon of irregular punching, and the underlying material will not be scratched during operation.

[0041] In some embodiments, as Figure 1 shown, the backplane puncher further includes a positioning structure 300, and the positioning structure 300 is used to define the relative positions of the first base 110 and the second base 210. By setting the positioning structure 300 to position the relative positions of the first base 110 and the second base 210, the punching position of the punching knife 120 on the backplane becomes more accurate.

[0042] In some embodiments, the relative positions of the first base 110 and the second base 210 can be defined by using a mechanism of snap protrusion and snap groove connection.

[0043] In this embodiment, as Figure 1 shown, the positioning structure 300 includes a first magnet 310 provided on the first base 110 and a second magnet 320 provided on the second base 210, and the first magnet 310 and the second magnet 320 can adsorb each other. By providing the first magnet 310 on the first base 110 and the second magnet 320 on the second base 210, and the first magnet 310 and the second magnet 320 adsorb each other, the relative positions of the first base 110 and the second base 210 are defined. In this application, the relative positions of the first base 110 and the second base 210 are defined by the mutual adsorption of the first magnet 310 and the second magnet 320, which is convenient for punching holes in the backplane, a material that is far from the edge and cannot be folded, so as to achieve the effect of free punching positions.

[0044] Specifically, as Figure 1 shown, both the first magnet 310 and the second magnet 320 are provided with a plurality of them, and the plurality of first magnets 310 and the plurality of second magnets 320 are adsorbed in one-to-one correspondence. By providing a plurality of first magnets 310 and a plurality of second magnets 320, and the plurality of first magnets 310 and the plurality of second magnets 320 are adsorbed in one-to-one correspondence, the positioning accuracy of the first base 110 and the second base 210 is improved.

[0045] More specifically, as Figure 1As shown, a plurality of first magnets 310 are arranged circumferentially around the first base 110, and a plurality of second magnets 320 are arranged circumferentially around the second base 210. The plurality of first magnets 310 are arranged circumferentially around the first base 110, and the plurality of second magnets 320 are arranged circumferentially around the second base 210, so that the circumferences of the first base 110 and the second base 210 are aligned.

[0046] Further, as Figure 1 shown, the first punching layer structure includes an end cap 130. A through hole 111 for the punching knife 120 to pass through is provided on the first base 110. One end of the punching knife 120 facing away from the second base 210 is connected to the end cap 130. The punching knife 120 passes through the through hole 111 of the first base 110, and one end of the punching knife 120 facing away from the second base 210 is connected to the end cap 130. The end cap 130 drives the punching knife 120 to move along the axial direction of the through hole 111. When performing the punching operation, the operator holds the end cap 130 and presses the end cap 130, so that the punching knife sequentially passes through the through hole 111, the back plate, and the knife groove 220, thereby punching the back plate.

[0047] Specifically, as Figure 1 shown, the first punching structure 100 further includes an elastic member 140. The elastic member 140 is disposed between the end cap 130 and the first base 110. The elastic member 140 can push the end cap 130 to move away from the first base 110 through its own elastic force. By providing the elastic member 140, one end of the elastic member 140 abuts against the end cap 130, and the other end abuts against the first base 110. After the back plate punching is completed, without external force, the elastic member 140 resets, thereby pushing the end cap 130 to move away from the first base 110 through its own elastic force, driving the end cap 130 to reset, and the end cap 130 is connected to the punching knife 120, thereby driving the punching knife 120 to reset.

[0048] More specifically, the elastic member 140 is a spring, and the elastic member 140 is sleeved on the punching knife 120.

[0049] More specifically, as Figure 1 shown, a first receiving groove 131 is provided on the end cap 130. The punching knife 120 is connected to the groove wall of the first receiving groove 131. A second receiving groove 112 is provided on the side of the first base 110 facing away from the second base 210. Both ends of the elastic member 140 abut against the groove wall of the first receiving groove 131 and the groove wall of the second receiving groove 112. By providing the first receiving groove 131 on the end cap 130 and the second receiving groove 112 on the first base 110, both ends of the elastic member 140 abut against the groove wall of the first receiving groove 131 and the groove wall of the second receiving groove 112, so as to facilitate the accommodation of the elastic member 140.

[0050] More specifically, the size of the second receiving groove 112 is larger than the size of the first receiving groove 131.

[0051] Specifically, a first cushion block is arranged on one side of the first seat 110 close to the second seat 210. Arranging the first cushion block on the first seat 110 can prevent the first seat 110 and the second seat 210 from being damaged when they are in contact. More specifically, the first cushion block is a sponge body.

[0052] Specifically, a second cushion block is arranged on one side of the second seat 210 close to the first seat 110. Arranging the second cushion block on the second seat 210 can prevent the first seat 110 and the second seat 210 from being damaged when they are in contact. More specifically, the second cushion block is a sponge body.

[0053] In some embodiments, when the first seat 110 and the second seat 210 cooperate with each other to clamp the back plate, the first cushion block on the first seat 110 and the second cushion block on the second seat 210 can abut against each other.

[0054] In some embodiments, when the first seat 110 and the second seat 210 cooperate with each other to clamp the back plate, the first cushion block on the first seat 110 and the second cushion block on the second seat 210 are staggered, the first cushion block abuts against the second seat 210, and the second cushion block abuts against the first seat 110.

[0055] It can be understood that the relative positional relationship between the first cushion block and the second cushion block is set according to actual operation needs.

[0056] This application also provides a punching production line, including the back plate punching device of any one of the above. The back plate is punched by using the back plate punching device, so as to perform pipeline operation and improve the punching efficiency.

[0057] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0058] The above-described embodiments only represent several implementation manners of this application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of this application, several deformations and improvements can still be made, and these all belong to the protection scope of this application. Therefore, the protection scope of the patent of this application should be subject to the appended claims.
