Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaics, and in particular relates to a simple handheld edge trimming tool for photovoltaic components. Background Art

[0002] In the manufacturing process of photovoltaic modules, the laminated parts of photovoltaic modules are laminated by placing backboard (tempered glass), EVA / POE / PVB film, solar cell, EVA / POE / PVB film and tempered glass in sequence from bottom to top. After lamination, the excess EVA / POE / PVB film and backboard on the edge of the photovoltaic module need to be eliminated. At present, in the manual semi-automatic line workshop, only the commonly used edge trimming tools such as utility knife or self-made edge trimming tool are used for cutting. The existing edge trimming tool is a handle rod fixedly connected to the handle, and a handle head connected to the handle rod as a whole. The blade is detachably connected to the end of the handle head by at least two bolts. The opening direction of the V-shaped notch is parallel to the length direction of the handle head. It is not easy for the operator to grasp the cutting direction and cutting force, resulting in uneven cutting. When one side of the V-shaped notch is blunt, it is necessary to remove two bolts to adjust to the other V-shaped notch. The operation is cumbersome and affects the production rhythm. It will also scratch the glass surface and the backboard surface of the photovoltaic module during use and disassembly. It is also inconvenient for operators to use, and scratch accidents often occur.

[0003] When using a utility knife to trim the edges, firstly, the blade of the utility knife is easy to break, and the blade that flies out after breaking is easy to hurt people, and the amount of scrapped blades during use is too large, resulting in too high production costs; secondly, when the utility knife is used, the distance between the force point of the utility knife and the holdable part is small, that is, the force arm is too small, which increases the labor intensity of the operator. For some homemade trimming tools, since the EVA overflowing from the corners during the trimming of photovoltaic modules usually cannot be trimmed at one time, for the untrimmed parts at the four corners, the blade edge on the other side of the trimming tool is made close to the edge of the tempered glass, and the blade is pulled back. After trimming one side, the remaining three sides are eliminated in the same way. Pulling the blade back will bring great inconvenience to the operator's operation, which may cause uneven force on the excess EVA / POE / PVB film of the tempered glass, resulting in burrs, and the blade needs to be pulled back and forth, affecting production efficiency.

[0004] CN204566868U A photovoltaic module edge cutting tool, including a blade and a handle, the blade includes a blade body and two V-shaped notches on both sides of the blade body, and the bottom of any of the V-shaped notches is provided with an arc-shaped blade; the handle includes a handle, a handle rod fixedly connected to the handle, and a handle head connected to the handle rod as a whole; the angle between the handle head and the handle rod is an obtuse angle, the blade is detachably connected to the end of the handle head by at least two bolts, and the opening direction of the V-shaped notch is parallel to the length direction of the handle head. The above patent has the following defects and problems:

[0005] 1. Complexity of blade replacement: Although the blade is detachably connected to the handle head by bolts, frequent blade replacement may require some tools and time, which may reduce work efficiency. In addition, if the bolts are not tightened well, the blade may become loose, affecting the quality of edge cutting.

[0006] 2. Durability of the V-notch and blade: The V-notch and arc-shaped blade are the core parts of the tooling. Long-term use or improper use may cause wear of these parts, affecting the accuracy and effect of edge cutting.

[0007] 3. Limitations of tool handle design: The angle between the tool handle head and the tool handle rod is an obtuse angle. This design may limit the use of the tool in certain working environments with specific angles or limited space.

[0008] 4. Skill requirements for operators: Although the design of the tooling can simplify the operation process, the operator is still required to have certain skills and experience to ensure the quality and safety of edge cutting.

[0009] 5. Further improvement of safety: Although the tooling design has taken operational safety into consideration, the risk of accidental injury can be further reduced by adding protective devices or improving the design. Summary of the invention

[0010] The purpose of the utility model is to solve the problems of the above-mentioned background technology that the blade of the utility knife is easy to break and injure people, the force arm is too small to increase the labor intensity and the shortcomings of the above-mentioned patent CN204566868U, and to provide a simple handheld edge trimming tool for photovoltaic components. The handheld edge trimming tool of the utility model is effective in trimming the residual EVA / POE / PVB film on the edge of the glass, and will not cause inconvenience in operation due to adjusting the angle between the edge trimming tool and the edge of the component, thereby improving production efficiency and effectively reducing production costs.

[0011] The technical solution adopted by the utility model is:

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments to facilitate a clear understanding of the present invention, but they do not constitute a limitation on the present invention.

[0027] like Figure 1-3 As shown, the utility model is a simple hand-held edge trimming tool for photovoltaic modules, comprising a blade 1 and a handle 2. The blade 1 comprises a blade body 14 and two symmetrical V-shaped notches 11 formed in a W shape on the blade body 14, which is conducive to calibrating the cutting direction and position, and can change the edge trimming angle, making it more flexible and convenient to use; a circular arc-shaped blade 13 is provided at the bottom of each V-shaped notch 11, and a bolt fixing hole 12 is provided in the middle of the blade body 14; Figure 2As shown, the handle 2 includes a handle 22, a handle rod 25 fixedly connected to the handle 22, and a handle head 21 connected to the handle rod 25 as a whole. The blade force point and the handle are designed according to the principle of mechanics. There is a distance of the handle rod between the blade force point and the handle, that is, the force arm is longer, and the same operation effect is achieved with less effort; the handle head 21 and the handle rod 25 are parallel in the length direction, and a mounting groove 23 is provided on the handle head 21. A bolt nesting hole 24 is provided on the handle head 21 perpendicular to the direction of the mounting groove 23. The blade 1 is detachably connected to the mounting groove 23 at the end of the handle head 21 by a bolt 3, and there will be no shaking phenomenon, thereby increasing the safety of the operation. At the same time, since the blade is detachable, the blade can be replaced or processed at any time as needed, avoiding waste of resources; at this time, the direction of the V-shaped notch: the opening direction of the two V-shaped notches 11 of the blade 1 is parallel to the length direction of the handle head 21. This design allows the opening direction of the V-shaped notch to be intuitively judged according to the length direction of the handle head 21 during use, so that the edge cutting operation can be performed more conveniently. At the same time, it also ensures that the blade can maintain a stable posture during the edge cutting process, improving operation accuracy and efficiency.

[0028] The blade 1 of the utility model is made of high-quality stainless steel to ensure hardness and toughness. The handle head 21 and the handle rod 25 are integrally formed of ordinary stainless steel. The handle 22 is made of rubber material with a mesh pattern to increase friction. Of course, the handle 22 can be made of plastic material or wood material. The bolt 3 is a stainless steel M3 bolt.

[0029] Especially when the blade, handle head and handle body are set at an angle of 120°, such as Figure 4 As shown, the best effect is achieved in the process of removing the residual EVA / POE / PVB film on the edge of the glass. There is no inconvenience in the operation due to adjusting the angle between the edge trimming tooling and the edge of the component, which improves production efficiency and can effectively reduce production costs.
