[0031] See also Figure 1 An embodiment of the present application provides a photovoltaic module edge trimming device, comprising an edge trimming mechanism 1 and a material tearing mechanism 2. The edge trimming mechanism 1 is used to trim excess adhesive film overflowing from the edge of the photovoltaic module. The material tearing mechanism 2 is used to tear off the trimmed adhesive film so that the trimmed adhesive film will not follow the movement of the photovoltaic module and cause the assembly line to get stuck.

[0032] In a specific configuration, the trimming mechanism 1 has a trimming knife 11, which can move along a first direction, wherein the first direction is parallel to the side of the photovoltaic module, and the blade of the trimming knife 11 is perpendicular to or inclined to the first direction, so that the trimming knife 11 can trim the overflowed excess glue at the side of the photovoltaic module when moving along the first direction.

[0033] The material pulling mechanism 2 is arranged on the edge trimming mechanism 1 and is spaced apart from the edge trimming knife 11 along a second direction, the second direction being perpendicular to the first direction, so that the film cut by the edge trimming knife 11 can fall onto the material pulling mechanism 2. The material pulling mechanism 2 is provided with an opening 3, the opening 3 faces the blade of the edge trimming knife 11, and the film can fall into the opening 3 when it falls and will not scatter.

[0034] See also Figure 1-Figure 2 The material-tearing mechanism 2 has a first anti-slip portion 31 and a second anti-slip portion 32. The first anti-slip portion 31 is located in the opening 3 and is arranged opposite to the blade of the trimming knife 11. The second anti-slip portion 32 is located in the opening 3 and is connected to the first anti-slip portion 31, and the extension direction of the first anti-slip portion 31 intersects with the extension direction of the second anti-slip portion 32. After falling into the opening 3, the rubber film can contact the first anti-slip portion 31 and the second anti-slip portion 32, thereby enhancing the friction between the rubber film and the material-tearing mechanism 2. While preventing the rubber film from being detached from the opening 3 when the material-tearing mechanism 2 moves with the trimming mechanism 1, the rubber film can be torn off when the material-tearing mechanism 2 moves with the trimming mechanism 1, thereby avoiding the collected residual rubber film from accumulating on the opening 3, thereby ensuring the material-tearing effect.

[0035] When the photovoltaic module edge trimming device of the present application is in use, the edge trimming mechanism 1 can be controlled to drive the edge trimming knife 11 and the material tearing mechanism 2 to move along a first direction parallel to the side of the photovoltaic module, and the excess adhesive film overflowing from the side of the photovoltaic module can be trimmed by the edge trimming knife 11, and the trimmed adhesive film can fall into the opening 3 of the material tearing mechanism 2, so that the trimmed adhesive film can be collected at the opening 3, and the friction between the adhesive film and the material tearing mechanism 2 is enhanced by the first anti-slip portion 31 and the second anti-slip portion 32, so that the adhesive film can be torn off when the material tearing mechanism 2 moves with the edge trimming mechanism 1, thereby avoiding the situation where the collected residual adhesive film accumulates on the opening 3, and by timely processing the trimmed residual adhesive film, the problem that the assembly line is easily stuck due to the residual adhesive film, causing equipment failure, is solved.

[0036] In one embodiment, the angle between the second anti-slip portion 32 and the first anti-slip portion 31 is less than or equal to 90°, so that the adhesive film can be better gathered in the opening 3 and is not easy to slip out, and is also easier to be torn off under the cooperation of the second anti-slip portion 32 and the first anti-slip portion 31. Specifically, the first anti-slip portion 31 is perpendicular to the first direction, and the second anti-slip portion 32 is parallel to the first direction. When the cut adhesive film falls onto the material tearing mechanism 2, the adhesive film first contacts the second anti-slip portion 32 in the opening 3, and then contacts the first anti-slip portion 31, and then is torn off by the cooperation of the second anti-slip portion 32 and the first anti-slip portion 31 during the movement of the material tearing mechanism 2.

[0037] See also Figure 2-Figure 3In one embodiment, the first anti-slip portion 31 has a sawtooth structure; and / or the second anti-slip portion 32 has a sawtooth structure, which can increase the friction between the adhesive film and the first anti-slip portion 31 or the second anti-slip portion 32, and make the adhesive film easier to be torn off under the cooperation of the second anti-slip portion 32 and the first anti-slip portion 31. Specifically, in one embodiment, the second anti-slip portion 32 has a sawtooth structure to ensure the stability of the adhesive film in the opening 3, and the first anti-slip portion 31 has a sawtooth structure or a cutting structure to enable the adhesive film to be torn off in the opening 3. In another embodiment, the second anti-slip portion 32 has an anti-slip pattern structure to ensure the stability of the adhesive film in the opening 3, and the first anti-slip portion 31 has a sawtooth structure to enable the adhesive film to be torn off or cut off in the opening 3.

[0038] In one embodiment, the sawtooth structure includes a plurality of sawteeth, and the distance between two adjacent sawteeth is 0.5mm-2.5mm. Specifically, along the first direction, the second anti-slip portion 32 is provided with a plurality of sawteeth with uniform spacing, and the distance between two adjacent sawteeth is 0.5mm-2.5mm. Along the second direction, the first anti-slip portion 31 is provided with a plurality of sawteeth with uniform spacing, and the distance between two adjacent sawteeth is 0.5mm-2.5mm. This spacing can not only prevent the contracted film from slipping and facilitate tearing of the film, but also prevent the film from getting stuck between two adjacent sawteeth and affecting the tearing effect.

[0039] See also Figure 1-Figure 3 In one embodiment, the material pulling mechanism 2 includes a fixing part 21, a connecting part 22 and a material pulling part 23. The fixing part 21, the connecting part 22 and the material pulling part 23 can all be made of a stainless steel plate with a thickness of 1mm-3mm to ensure the strength and toughness of the material pulling mechanism 2, so that the material pulling mechanism 2 is not easy to break or deform.

[0040] The fixing component 21 is provided with a fixing opening, and the fixing component 21 can be fixedly connected to the edge trimming mechanism 1 through the fixing opening with bolts, so as to fix the material pulling mechanism 2 to the edge trimming mechanism 1. The connecting component 22 is connected to the fixing component 21, and the material pulling component 23 is connected to the connecting component 22 and is spaced apart from the fixing component 21 along the second direction. An opening 3 is formed between one end of the material pulling component 23 away from the connecting component 22 and one end of the fixing component 21 away from the connecting component 22. The first anti-slip portion 31 is provided on the connecting component 22, and the second anti-slip portion 32 is provided on the material pulling component 23. Specifically, one side of the connecting component 22 is connected to the fixing component 21 and is perpendicular to the fixing component 21, and the other side of the connecting component 22 is connected to the material pulling component 23, and the material pulling component 23 is parallel to the fixing component 21. This structure can make the material pulling component 23 and the fixing component 21 have a certain distance in the direction perpendicular to the first direction and the second direction, so that the material pulling component 23 and the connecting component 22 can cooperate to form an opening 3. In addition, the distance between the fixing component 21 and the material-tearing component 23 is consistent with the length of the first anti-slip portion 31 to ensure the contact effect between the adhesive film and the first protective portion, thereby ensuring the material-tearing effect.

[0041] In one embodiment, the material tearing mechanism 2 further includes a guide component 24, which is disposed at one end of the material tearing component 23 away from the connecting component 22, and a guide surface 241 is disposed on the side of the guide component 24 close to the fixing component 21, and the guide surface 241 is an inclined surface inclined toward the side away from the fixing component 21. Through the provision of the guide component 24, the cut rubber film can first contact the guide component 24, and under the guidance of the guide surface 241, move to the material tearing component 23 and the opening 3 for collection and tearing operations.

[0042] Specifically, the guide component 24 is trapezoidal, and has a first side 242 and a second side 243 parallel to the second direction. The guide surface 241 is arranged between the first side 242 and the second side 243, and is inclined to the first direction. The second side 243 is connected to the material-tearing component 23, and along the second direction, the length of the first side 242 is shorter than the length of the second side 243. When the trimming mechanism 1 drives the trimming knife 11 and the material-tearing mechanism 2 to move, the trimming knife 11 can trim the excess film overflowing from the side of the photovoltaic module, and the trimmed film can be guided to the opening 3 of the material-tearing mechanism 2 through the guide surface 241, so that the trimmed film can be collected in the opening 3, so that the film can be torn off later through the cooperation of the first anti-slip part 31 and the second anti-slip part 32.

[0043] In one embodiment, along the first direction, the length ratio of the guide component 24 to the photovoltaic module edge trimming device is 3:5, and this size can ensure the guiding effect of the guide component 24 on the adhesive film, so that the adhesive film can be smoothly moved into the opening 3. Specifically, along the first direction, the length of the guide component 24 is 80mm-160mm, and the length of the photovoltaic module edge trimming device is 140mm-260mm. More specifically, in the present application, along the first direction, the length of the guide component 24 is 120mm, and the length of the photovoltaic module edge trimming device is 200mm. Along the second direction, the length of the photovoltaic module edge trimming device is 40mm, the length of the material pulling component 23 is 20mm, and the lengths of the first side 242 and the second side 243 are 9.5mm and 20mm, respectively. This size allows the guide component 24 to smoothly guide the adhesive film to the material pulling mechanism 2 when it moves with the material pulling mechanism 2 to guide and converge the adhesive film, so that the adhesive film can be collected and torn in the opening 3.

[0044] In one embodiment, along the second direction, the spacing between the fixing member 21 and the first anti-slip portion 31 is 10mm-30mm. Specifically, along the second direction, the spacing between the first anti-slip portion 31 and the edge trimming knife 11 is 10mm-30mm, and more specifically, along the second direction, the spacing between the first anti-slip portion 31 and the blade of the edge trimming knife 11 is 10mm-30mm. This spacing allows a certain clearance distance between the opening 3 and the edge trimming knife 11, so that the material pulling mechanism 2 will not interfere with the normal edge trimming effect of the edge trimming mechanism 1.

[0045] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0046] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
