The solar panel components that are tightly combined with cells and other materials through the lamination process form a complete solar panel. Among them, the trimming of laminated cells is an important step in the production process of solar cell components. When the photovoltaic laminate is laminated, due to the poor laying accuracy of the encapsulation film and the misalignment in the laminator cavity, residual film will be formed on the side and edge of the back panel of the photovoltaic laminate.

Brittle and hard residual adhesive film is difficult to cut directly, they are not easy to deform and are easy to break, which will not only affect the appearance quality of photovoltaic modules, but may also have a negative impact on the performance and reliability of the modules.

[0030] In summary, due to the use of the photovoltaic laminate trimming device of the above technology, the beneficial effects of the present invention are:

[0031] 1. Through the provided driving mechanism, cutting mechanism and reducing mechanism, when the rotating disk rotates, the rotating disk guides the adjusting rod to move under the guidance of the second guide groove through the first guide groove. Since the second guide groove is a straight groove and the outer wall of the adjusting rod is tightly fitted with the inner wall of the second guide groove, and the second slide rail restricts the moving direction of the slide table, the adjusting rod will not deflect during the movement, and the tool mounting seat can remain vertical during the movement, ensuring that the tip of the trimming knife can be vertically fitted on the surface of the residual glue of the film, and a cutting groove is left on the surface of the residual glue of the film as the trimming knife moves. Through the cutting groove, the force and accuracy required for cutting can be reduced, making the cutting process easier to control, and the cutting groove can guide the breaking process, making the fracture surface of the residual glue of the film smoother and more regular, which helps to reduce the debris and burrs generated during the cutting process and improve the smoothness and accuracy of the cutting surface;

[0032] 2. Through the transmission mechanism and the knocking mechanism, when the edge trimming knife moves for cutting, the knocking column knocks the outer edge of the residual adhesive film by reciprocating up and down, and fine cracks are generated in the cutting groove under the action of knocking, so that the stress in the cutting groove is further concentrated, and the brittle residual adhesive film can be broken more easily along the cutting groove, thereby achieving the purpose of reducing the generation of unstable fracture surfaces;

[0033] 3. Through the provided buckle and tooth groove, the first roller is pressed against the surface of the laminated battery cell and rotated clockwise. At this time, the vertical part of the tooth of the buckle is in contact with the vertical surface of the inner wall of the tooth groove. Since the tooth cannot be rotated out of the tooth groove as in counterclockwise rotation, the second roller drives the third shaft to rotate through the cooperation of the buckle and the tooth groove. The torque generated by the second roller can be transmitted to the third shaft. The third shaft can drive the knocking column to knock at this time. Since the cutting groove has been completely produced, knocking can normally produce fine cracks in the cutting groove. When the residual adhesive of the film is thin enough, the edge can be broken and detached directly by knocking and cooperating with its own gravity, eliminating the step of applying force to break it and detach it.

[0053] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technology of a photovoltaic laminate trimming device in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] In order to solve the problem that in the actual processing process, if the residual adhesive film is not cleaned in time and exposed to an adverse environment, its texture may become brittle and hard, and the brittle and hard residual adhesive film is difficult to cut directly, is not easy to deform and is easy to break, which not only affects the appearance quality of the photovoltaic module, but also may have a negative impact on the performance and reliability of the module, the present invention proposes a photovoltaic laminate trimming device, such as Figure 1 - Fig.12 As shown:

[0055] The trimming device body 10 includes a first slide rail 12 and a shell 11 arranged on the first slide rail 12, a cylinder 13 is installed on the shell 11, and two trimming knives 14 are installed at the end of the cylinder 13, a laminated battery sheet is placed between the two trimming knives 14, and there is adhesive film residue on the laminated battery sheet, the shell 11 can reciprocate on the first slide rail 12, a cutting mechanism 30 is installed at the end of the cylinder 13, and the cutting mechanism 30 includes an abutment plate 31 installed at the end of the cylinder 13 and two tool mounting seats 34 with variable spacing arranged on the abutment plate 31, by starting the cylinder 13, the two cylinders 13 are extended and drive the abutment plates 31 to fit on both sides of the laminated battery sheet, so as to adjust the position of the surface of the laminated battery sheet. Pre-limiting prevents it from shifting during the cutting process. A trimming knife 14 is mounted on the tool mounting seat 34. The trimming knife 14 changes distance with the two tool mounting seats 34 to fit the surface of the residual glue on the film. When the shell 11 moves horizontally along the length direction of the first slide rail 12, the trimming knife 14 can leave a cutting groove on the residual glue on the film. Through the cutting groove, the force and accuracy required for cutting can be reduced, making the cutting process easier to control, and the cutting groove can guide the breaking process, making the fracture surface of the laminated battery cell smoother and more regular, which helps to reduce the debris and burrs generated during the cutting process and improve the smoothness and accuracy of the cutting surface. At the same time, to ensure the uniformity of the cutting groove, the trimming knife 14 will move back and forth on the surface of the laminated battery cell.

[0056] like Figure 4 , Figure 5 and Figure 7 As shown, the cutting mechanism 30 further includes two second slide rails 32 mounted on the abutment plate 31, a first rotating shaft 341 and a second roller 36 disposed on a tool mounting seat 34, a slide table 33 is slidably disposed on the second slide rails 32, and the tool mounting seat 34 is mounted on the slide table 33;

[0057] A rotating table 342 is rotatably arranged on the first rotating shaft 341, and a first roller 35 symmetrical to the second roller 36 is arranged on the rotating table 342. After the two tool mounting seats 34 are changed in pitch, the first roller 35 and the second roller 36 are respectively attached to the top and bottom surfaces of the laminated battery sheet;

[0058] In the process of making the two trimming knives 14 fit on the surface of the laminated battery cell, the two slides 33 drive the tool mounting seat 34 to move under the guidance of the second slide rail 32, and the trimming knives 14 set on the tool mounting seat 34 move accordingly, and the distance between the two trimming knives 14 is shortened and fit on the surface of the residual adhesive film. At the same time, the tool mounting seat 34 drives the first roller 35 and the second roller 36 to fit on the surface of the laminated battery cell, thereby achieving the purpose of reinforcing the position of the laminated battery cell, so that it cannot be lifted or drooped during the cutting process, and avoiding uneven cutting grooves caused by changes in the position of the laminated battery cell;

[0059] In order to facilitate the replacement of the trimming knife 14, the rotating table 342 can be rotated so that the rotating table 342 rotates around the first rotating shaft 341. After the first roller 35 rotates and deviates, the trimming knife 14 will not be hindered by the first roller 35 during the process of installing it between the first roller 35 and the second roller 36.

[0060] like Figure 1 and Figure 6 The housing 11 is provided with a driving mechanism 20 and a reducing mechanism 40, and the position of the tool mounting seat 34 is adjusted by the reducing mechanism 40, wherein the reducing mechanism 40 comprises a rotating disk 41 rotatably arranged on the housing 11 and two axially symmetrical second guide grooves 44 provided on the abutting plate 31, an arc-shaped first guide groove 42 is provided on the surface of the rotating disk 41, and an adjusting rod 43 is slidably embedded inside the first guide groove 42, the adjusting rod 43 passes through the second guide groove 44 and is connected to the tool mounting seat 34, the adjusting rod 43 can move horizontally inside the first guide groove 42 as the cylinder 13 extends, the rotating disk 41 is driven to rotate by the driving mechanism 20, and the adjusting rod 43 drives the tool mounting seat 34 to move when the rotating disk 41 rotates;

[0061] When the rotating disk 41 rotates, the rotating disk 41 guides the adjustment rod 43 to move under the guidance of the second guide groove 44 through the first guide groove 42. Since the second guide groove 44 is a straight groove and the outer wall of the adjustment rod 43 is tightly fitted with the inner wall of the second guide groove 44, and the second slide rail 32 restricts the moving direction of the slide 33, the adjustment rod 43 will not deflect during the movement, and the tool mounting seat 34 can remain vertical during the movement, ensuring that the tip of the trimming knife 14 can be vertically fitted on the surface of the residual glue of the film, so as to achieve the purpose of making the cutting line distributed in a straight line and uniform in depth, avoiding the deviation or distortion of the cutting line caused by angle deviation. When the angle deviates, the stress generated by cutting may be concentrated in a certain area, causing the area to rupture first, and the vertical cutting angle can disperse the stress and reduce the risk of the residual glue of the film breaking.

[0062] The rotating disk 41 is driven to rotate by the driving mechanism 20. The driving mechanism 20 includes a servo motor 21 arranged on the shell 11. A first driving wheel 22 is arranged on the output end of the servo motor 21. A first driven wheel 23 is arranged on the rotating disk 41. The surfaces of the first driving wheel 22 and the first driven wheel 23 are sleeved with a first transmission belt 24 for transmission. When the position of the trimming knife 14 needs to be adjusted, the servo motor 21 is started so that the servo motor 21 drives the first driven wheel 23 to rotate through the first driving wheel 22 and the first transmission belt 24, so that the first driven wheel 23 can drive the rotating disk 41 to rotate to adjust the position of the trimming knife 14.

[0063] During the cutting process, even if the depth of the cutting groove is relatively uniform, an unstable fracture surface may still be generated during the fracture process. The reason for this is that the stress at the cutting groove is not enough to make it fracture easily. In order to avoid this situation, a knocking mechanism 60 is installed on the tool mounting seat 34. The knocking mechanism 60 includes a connecting member 65 arranged on the tool mounting seat 34, a slide groove 66 arranged on the connecting member 65, and a slider 67 slidably arranged inside the slide groove 66. A knocking column 68 is installed on the slider 67. When the trimming knife 14 moves for cutting, the knocking column 68 knocks the outer edge of the residual glue of the film by reciprocating up and down. Under the action of knocking, fine cracks are generated in the cutting groove, so that the stress in the cutting groove is further concentrated, and the brittle residual glue of the film can be more easily broken along the cutting groove, thereby achieving the purpose of reducing the generation of unstable fracture surfaces.

[0064] The knocking column 68 is driven by the transmission mechanism 50. Figure 8 As shown, the transmission mechanism 50 includes a third rotating shaft 51 rotatably disposed on the tool mounting seat 34 and a mounting frame 53 mounted on the tool mounting seat 34, and a fourth rotating shaft 54 ​​is rotatably disposed on the mounting frame 53;

[0065] The fourth rotating shaft 54 ​​and the third rotating shaft 51 are both rotatably provided with transmission wheels 52, and the surfaces of the plurality of transmission wheels 52 are sleeved with second transmission belts 56 for transmission. When the housing 11 moves, the housing 11 drives the second roller 36 to roll in contact with the laminated battery sheet through the tool mounting seat 34. When the second roller 36 rolls, the second transmission belt 56 is driven to move through the third rotating shaft 51, so that the second transmission belt 56 drives the fourth rotating shaft 54 ​​to rotate under the restriction of the mounting frame 53 through another transmission wheel 52. Fig.11 and Fig.12 As shown, the knocking mechanism 60 also includes an eccentric wheel 61 arranged on the fourth rotating shaft 54 ​​and a sixth rotating shaft 64 arranged on the slider 67, and a fifth rotating shaft 62 is arranged at the end of the eccentric wheel 61, and a push rod 63 is sleeved and installed on the surface of the fifth rotating shaft 62, and the other end of the push rod 63 is sleeved and installed on the sixth rotating shaft 64. When the fourth rotating shaft 54 ​​rotates, the fourth rotating shaft 54 ​​drives the fifth rotating shaft 62 to rotate through the eccentric wheel 61, and the fifth rotating shaft 62 pushes the push rod 63 when it rotates, so that the push rod 63 pushes the slider 67 to move vertically inside the slide groove 66 through the sixth rotating shaft 64, and drives the knocking column 68 to move up and down reciprocatingly through the slider 67 to knock the residual glue of the adhesive film, thereby achieving the purpose of deepening the stress concentration in the cutting groove on the residual glue of the adhesive film.

[0066] In an optional embodiment, in order to improve the knocking effect of the knocking column 68, a tensioning roller 55 is provided in the middle of the second roller 36, and mounting frames 53 are provided on both sides of the tool mounting seat 34. The second transmission belt 56 is simultaneously sleeved on the transmission wheels 52 provided on the surfaces of the two fourth rotating shafts 54, and is tightened by the tensioning roller 55. Through this design, the knocking columns 68 provided on both sides of the trimming knife 14 can knock on the residual glue of the film at the same time, so as to increase the knocking frequency, increase the generation of cracks and improve the continuity between the cracks.

[0067] In an optional embodiment, during the first cutting, the thinner adhesive film residue is struck before the cutting groove is completely opened, which may easily cause the adhesive film residue to break directly. Fig. 9 and Fig.10 As shown, the inner wall of the second roller 36 is provided with a mounting groove 361, and a second rotating shaft 362 is arranged inside the mounting groove 361. A buckle 363 is rotatably arranged on the surface of the second rotating shaft 362, and the teeth at the end of the buckle 363 are horizontal on one side and inclined on the other side.

[0068] The third rotating shaft 51 is provided with a plurality of tooth grooves 511 equidistantly arranged around the surface thereof, which are matched with the teeth of the buckle 363 . The buckle 363 can be inserted into the tooth grooves 511 .

[0069] With this design, during the reciprocating cutting process of the edge trimming knife 14, the first roller 35 first adheres to the surface of the laminated battery sheet and rotates counterclockwise. At this time, after the inclined portion of the teeth of the buckle 363 contacts the inclined surface of the inner wall of the tooth groove 511, the buckle 363 can rotate with the second shaft 362 as the axis under the push of the tooth groove 511, and drive the teeth to be retracted into the installation groove 361. At this time, the torque generated by the rotation of the second roller 36 cannot be transmitted to the third shaft 51, so the third shaft 51 cannot drive the knocking column 68 to knock, thereby preventing the residual glue of the film from being broken due to knocking before the cutting groove is completely opened;

[0070] When the trimming knife 14 reaches the end of the battery cell and returns for secondary cutting, the first roller 35 adheres to the surface of the laminated battery cell and rotates clockwise. At this time, the vertical part of the teeth of the buckle 363 is in contact with the vertical surface of the inner wall of the tooth groove 511. Since the teeth cannot be rotated out of the tooth groove 511 as when rotating counterclockwise, the second roller 36 drives the third rotating shaft 51 to rotate through the cooperation of the buckle 363 and the tooth groove 511. The torque generated by the second roller 36 can be transmitted to the third rotating shaft 51. The third rotating shaft 51 can drive the knocking column 68 to knock. Since the cutting groove has been completely generated, the knocking can normally generate fine cracks in the cutting groove. When the residual adhesive of the film is thin enough, it can also be directly knocked and its edge can be broken and detached by its own gravity, eliminating the step of applying force to break it.

[0071] In order to enable the buckle 363 to be embedded in the new tooth groove 511 in time when the second roller 36 rotates counterclockwise, so as to avoid the situation that the buckle 363 is not embedded in the tooth groove 511 when the second roller 36 rotates clockwise, a torsion spring 364 is wound around the two side surfaces of the second rotating shaft 362, and the two ends of the torsion spring 364 are respectively connected to the inner wall of the installation groove 361 and the outer wall of the buckle 363. When the buckle 363 rotates around the second rotating shaft 362, the torsion spring 364 can be pulled to cause it to produce elastic deformation, thereby achieving the purpose of using the elastic deformation recovery of the torsion spring 364 to quickly reset the buckle 363 and embed it into the new tooth groove 511.

[0072] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field within the technical scope disclosed by the present invention, according to the technology of the present invention a photovoltaic laminate trimming device and its inventive concept to make equivalent replacement or changes should be covered within the protection scope of the present invention.
