[0002] With the development of science and technology, the utilization of energy is gaining more and more attention. The role of photovoltaic power generation technology in our daily life is becoming more and more prominent. Photovoltaic power generation technology can convert light energy into electrical energy, making full use of natural energy.

[0003] At present, the process of opening holes in the second film in the photovoltaic module processing workshop is as follows: the operator places the hole-positioning small material behind the stack welding machine, and the photovoltaic module flows into the second laying machine. The laying machine pulls the film and pulls it to the set position (middle position). The circular hole knife perforates the film. Figure 1 As shown, the cut circular film falls into the machine. The machine then continues to pull the film, completing the second pass. This method requires the operator to clean up the waste material regularly. During this process, the operator needs to reach deep into the machine, which can easily lead to safety accidents. Furthermore, this method requires the operator to place the small pieces, which incurs additional labor costs and increases the cost of the small pieces. Utility Model Content

[0029] In order to make the technical solutions and advantages of the embodiments of the present application more clearly understood, the exemplary embodiments of the present application are further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present application, and are not an exhaustive list of all the embodiments. It should be noted that the embodiments and features in the embodiments of the present application can be combined with each other unless they conflict.

[0030] Example 1

[0031] like Figure 2 As described above, this embodiment provides a film hole-making device for making holes in the film of a photovoltaic module 13. The film hole-making device includes two opposed vertical plates 1, two crossbars disposed between the two vertical plates 1, and multiple blades 5 disposed on each of the two crossbars. The blades 5 cut the film pulled from the film roller 6 by the clamping jaws 10.

[0032] Specifically, in this embodiment, two uprights 1 are arranged opposite each other, and a wider base plate can be provided at the bottom of each upright 1 to form a more stable mounting structure. Two crossbars, namely a first crossbar 2 and a second crossbar 3, are provided between the two uprights 1. The first crossbar 2 and the second crossbar 3 are parallel. Both the first crossbar 2 and the second crossbar 3 can slide up and down between the two uprights 1. The specific sliding structure can be implemented using slide rails, which are achievable in the prior art and are not specifically limited in this embodiment.

[0033] Multiple fixing seats 4 are provided on both the first crossbar 2 and the second crossbar 3, and the positions of the fixing seats 4 on the first crossbar 2 correspond to the fixing seats 4 on the second crossbar 3. That is, when viewed from the side of the first crossbar 2 or the second crossbar 3, and the line of sight is at the same height as the first crossbar 2 or the second crossbar 3, the fixing seats 4 on the first crossbar 2 and the fixing seats 4 on the second crossbar 3 overlap.

[0034] A blade 5 is fixed at the bottom of each fixing seat 4 of the first crossbar 2 and the second crossbar 3, and the cutting direction of the blade 5 is downward. The blade surface of the blade 5 on the first crossbar 2 faces the first direction, and the blade surface of the blade 5 on the second crossbar 3 faces the second direction, and there is an angle between the first direction and the second direction, such as Figure 3 shown.

[0035] When the film reaches the position of the first crossbar 2, the first crossbar 2 is controlled to move downward, so that the blade 5 on the first crossbar 2 cuts the film for the first time. Then the film is pulled further until the position of the first cut reaches the position of the second crossbar 3, and the second crossbar 3 is controlled to move downward, so that the blade 5 on the second crossbar 3 cuts the film for the second time. Repeating the above process can realize the automatic film hole opening process. Since there is a certain angle between the blade 5 on the first crossbar 2 and the blade 5 on the second crossbar 3, the film can be formed as follows: Figure 4 The “×”-shaped hole shown, compared with the traditional circular hole, does not generate waste, and the operator does not need to place small materials in advance, reducing small materials and labor costs. At the same time, there is no need to clean the machine, reducing safety hazards.

[0036] In some optional embodiments, the plurality of fixing seats 4 of the first cross bar 2 and the second cross bar 3 are arranged at equal intervals, thereby ensuring the consistency of the openings of the adhesive film.

[0037] In some optional embodiments, for photovoltaic modules with special requirements or unusual dimensions, the film openings may not be evenly spaced. To address this, in this embodiment, the first and second crossbars 2 and 3 are slidably connected to the mounting base 4, allowing the film openings to be positioned differently depending on the application.

[0038] In some optional embodiments, the angle between the first and second directions is between 30° and 90°, thereby meeting the film opening size requirements for almost all photovoltaic modules 13. This angle can be set to 30°, 45°, 60°, 75°, or 90°, etc., and is not specifically limited in this embodiment. Generally speaking, a 45° angle between the first and second directions can meet the film opening requirements for most photovoltaic modules 13.

[0039] In some optional embodiments, to facilitate smoother film cutting by the blade 5 during the film perforation process, the width of the blade 5 gradually decreases from top to bottom. For example, the blade 5 may be designed in a triangular shape, with one side of the blade 5 fixedly connected to the fixing base 4. In this way, the end of the blade 5 is angled, facilitating film cutting.

[0040] Example 2

[0041] This embodiment provides a laying machine, which includes a film hole-making device. The film hole-making device can refer to the content described in Example 1 and will not be described in detail in this embodiment.

[0042] In this embodiment, the laying machine is further provided with a film roller 6, such as Figure 5 As shown. The film roller 6 is arranged on one side of the two vertical plates 1, and the film is wound on the film roller 6. Two vertical poles 7 are provided on the other side of the two vertical plates 1, and the two vertical poles 7 are in a one-to-one correspondence with the two vertical plates 1. A horizontal slide rail 8 is provided between each vertical pole 7 and the corresponding vertical plate 1. A crossbeam 9 is provided between the two slide rails 8. The crossbeam 9 can move back and forth through the two slide rails 8. A clamp 10 is provided on the crossbeam 9. The clamp 10 can be used to pull the film on the film roller 6 and pull the film from one side of the two vertical poles 7 to the other side through the bottom of the blade 5.

[0043] In order to facilitate the movement of the film while allowing it to pass under the blade 5, the clamping portion of the clamping jaws 10 needs to be flush with the top of the film roller 6, and the top of the film roller 6 needs to be lower than the end of the blade 5. That is, the film is below the end of the blade 5 from the starting position when it comes out of the film roller 6 to the position where it is finally pulled by the clamping jaws 10.

[0044] In this embodiment, before the film is opened, it is necessary to manually place the film on the film roller 6 on the clamping jaws 10 in advance, and pull a length of the film through the clamping jaws 10 so that the film is spread flat under the blade 5 to complete the initial preparation work. Before the film is officially opened, the length of the film pulled out by the film roller 6 to the first crossbar 2 can be calculated by the software algorithm. When the film pulled out by the film roller 6 reaches the position of the first crossbar 2, the first crossbar 2 is controlled to move downward, so that the blade 5 on the first crossbar 2 performs the first cut on the film. Then the clamping jaws 10 continue to pull the film so that the position of the first cut of the film reaches the position of the second crossbar 3, and the second crossbar 3 is controlled to move downward, so that the blade 5 on the second crossbar 3 performs the second cut on the film. Repeating the above process can realize the automated film opening process. Since there is a certain angle between the blade 5 on the first crossbar 2 and the blade 5 on the second crossbar 3, the final film can be formed as follows Figure 4 The “×”-shaped hole shown, compared with the traditional circular hole, does not generate waste, and the operator does not need to place small materials in advance, reducing small materials and labor costs. At the same time, there is no need to clean the machine, reducing safety hazards.

[0045] In some optional embodiments, there are multiple clamping jaws 10, and the multiple clamping jaws 10 are arranged on the beam 9 at equal intervals, which can ensure that the force on the film is more uniform and the pulling process of the film is smoother.

[0046] In some optional embodiments, connecting plates 11 are provided on both sides of the film roller 6. The film roller 6 and the connecting plates 11 are rotatably connected, that is, the film roller 6 can rotate between the two connecting plates 11. The two connecting plates 11 are respectively fixed to the sides of the two vertical plates 1.

[0047] In some optional embodiments, a guide platform 12 is further provided between the two vertical plates 1 and the film roller 6. This guide platform 12 is located above and in front of the film roller 6, with the tip of the blade 5 higher than the top plane of the guide platform 12. The film from the film roller 6 is pulled through the guide platform 12 to below the blade 5. The guide platform 12 guides the film after it is pulled from the film roller 6, ensuring a smoother film. When the guide platform 12 is provided above and in front of the film roller 6, the position of the clamping jaw 10 can be adaptively adjusted based on the position of the guide platform 12.

[0048] It should be noted that the sliding structures involved in this embodiment can all be implemented by means of slide rails, and the technical solution for implementing sliding by slide rails is very mature. Those skilled in the art can implement it through existing technology, and this embodiment will not be described in detail.

[0049] The laying machine of this embodiment realizes secondary cutting of the film by setting two blades 5, forming an "X"-shaped hole on the film. Compared with the traditional circular hole, no waste is generated, and the operator does not need to place small materials in advance, reducing small materials and labor costs. At the same time, there is no need to clean the machine, reducing safety hazards.

[0050] Example 3

[0051] This embodiment provides a photovoltaic module assembly system comprising a conveyor belt and a laying machine. The laying machine can be described in conjunction with Examples 1 and 2. The conveyor belt is positioned between two uprights 7 and two uprights of the film perforation device, and beneath two slide rails 8, for conveying photovoltaic modules 13. The conveyor belt's conveying direction is perpendicular to the longitudinal direction of the slide rails 8.

[0052] Specifically, the photovoltaic module assembly system proposed in this embodiment can be implemented as a photovoltaic module assembly line. The laying machine can be installed in a link of the assembly line. The conveyor belt is used to transport the photovoltaic modules 13 to the rear end of the blade 5. After the blade 5 creates holes in the film, the film can be directly laid flat on the surface of the photovoltaic modules 13 for subsequent assembly.

[0053] Obviously, those skilled in the art may make various changes and modifications to this application without departing from the spirit and scope of this application. Thus, if these modifications and variations of this application fall within the scope of the claims of this application and their equivalents, this application is intended to include these modifications and variations.
