[0001] The utility model relates to the technical field of photovoltaic adhesive films, and more specifically to a forming device for an EPE photovoltaic adhesive film. Background Art

[0002] With the continuous development of the solar energy industry, the current solar photovoltaic module packaging process is to stack glass, EPE photovoltaic film, battery, and backplane neatly, put them into a laminator, evacuate and heat them, melt the EPE photovoltaic film to cross-link, and solidify them after cooling to obtain photovoltaic modules. The solar cell module is composed of high-efficiency crystalline silicon solar cells, ultra-white cloth-textured tempered glass, EPE photovoltaic film, backplane, and aluminum alloy frame. It has the characteristics of long service life and strong mechanical resistance to external pressure.

[0003] At present, when producing and processing EPE photovoltaic film, since EPE photovoltaic film is in the shape of foam sponge, EPE photovoltaic film of different specifications is required during production, so EPE photovoltaic film needs to be cut, but the existing cutting method can only cut one specification of EPE photovoltaic film at a time. When two specifications of EPE photovoltaic film need to be processed on the same production line, two types of cutting devices are required for processing, which results in additional costs in actual production and increases the floor space of the production line.

[0034] In this embodiment, through the cooperation between the second motor 10, the third motor 19, the hydraulic rod 11, the lifting platform 12, the second gear 13, the rack 14, the electric push rod 15, the first screw rod 8 and the second screw rod 18, the device can adjust the position of the first cutting knife 16 and the second cutting knife 21 so that the device can cut the photovoltaic film into different sizes when cutting the photovoltaic film, so that the cut photovoltaic film can be formed into different scales, which effectively solves the problem of requiring different molding devices when cutting the photovoltaic film into different sizes, thereby increasing the cost.

[0035] Example 2

[0036] See also Figure 5-6This embodiment is further optimized on the basis of embodiment 1. Specifically, a transmission shaft 3 is rotatably connected between the inner walls on both sides of the support frame 2. The number of the transmission shafts 3 is four, and the four transmission shafts 3 are respectively located between the inner walls on both sides of the two support frames 2.

The rotating shafts of the two first gears 5 pass through the support frame 2 and are fixedly connected to the two transmission shafts 3 respectively. A first motor 6 is fixedly connected to the side of one of the support frames 2, and the output shaft of the first motor 6 passes through the support frame 2 and is fixedly connected to one of the transmission shafts 3.

[0037] In this embodiment, through the cooperation between the transmission shaft 3, the conveyor belt 4, the first gear 5 and the first motor 6, the device can compress the longer photovoltaic film when conveying the photovoltaic film to fix the position of the photovoltaic film, and then move the fixed photovoltaic film to perform subsequent molding of the photovoltaic film, thereby avoiding the problem of needing to move the photovoltaic film but not being able to effectively fix the photovoltaic film when cutting and molding the photovoltaic film.

[0038] Working principle: When in use, the staff places one side of the photovoltaic film that needs to be cut and formed between the two conveyor belts 4, and then starts the first motor 6. After the first motor 6 is started, one of the transmission shafts 3 is rotated. After one of the transmission shafts 3 is rotated, multiple conveyor belts 4 are moved together through the conveyor belt 4 and the first gear 5 to compress the photovoltaic film. Then the conveyor belt 4 clamps the photovoltaic film and allows the photovoltaic film to enter between the two conveyor belts 4 to move the photovoltaic film. Then the hydraulic rod 11 is started to lower the lifting platform 12 so that the first cutting knife 16 penetrates the photovoltaic film. Then the second motor 10 rotates the first screw rod 8. After the first screw rod 8 rotates, the first moving block 9 drives the lifting platform 12 to move so that the first cutting knife 16 cuts the photovoltaic film. After the photovoltaic film is cut, the hydraulic rod 11 raises the first cutting knife 16, and the conveyor belt 4 continues to convey the photovoltaic film so that the cut part of the photovoltaic film moves to the conveyor belt 4 On the outside, the hydraulic rod 11 then makes the first cutting knife 16 descend again to cut the subsequent photovoltaic film. At this time, the second moving block 20 follows the lifting platform 12 to descend through the support plate 22, and then the third motor 19 makes the second screw rod 18 rotate so that the second moving block 20 drives the second cutting knife 21 to move. Then the second cutting knife 21 separates the cut photovoltaic film from the subsequent photovoltaic film to complete the molding of the photovoltaic film. After that, the staff can collect the molded photovoltaic film and the waste cut from the photovoltaic film. When the molding size of the photovoltaic film is adjusted, the electric push rod 15 can be used to move the rack 14, so that the second gear 13 can be used to move another rack 14. After that, the distance between the two first cutting knives 16 is adjusted to adjust the width of the photovoltaic film cutting. Then, the moving distance of the conveyor belt 4 and the first moving block 9 is adjusted to complete the adjustment of the molding length of the photovoltaic film.

[0039] In summary: the utility model, through the cooperation among the second motor 10, the third motor 19, the hydraulic rod 11, the lifting platform 12, the second gear 13, the rack 14, the electric push rod 15, the first screw rod 8 and the second screw rod 18, can enable the device to adjust the position of the first cutting knife 16 and the second cutting knife 21 so that the device can cut the photovoltaic film into different sizes when cutting the photovoltaic film so that the cut photovoltaic film can be formed into different scales, effectively solving the problem of requiring different molding devices when cutting the photovoltaic film into different sizes, thereby increasing the cost. Through the cooperation among the transmission shaft 3, the conveyor belt 4, the first gear 5 and the first motor 6, the device can compress the longer photovoltaic film when conveying the photovoltaic film, thereby fixing the position of the photovoltaic film and then moving the fixed photovoltaic film to perform subsequent molding of the photovoltaic film, avoiding the problem that the photovoltaic film needs to be moved but cannot be effectively fixed when cutting and molding the photovoltaic film.
