The specific meaning of the above terms in the present invention can be understood according to specific situations by those skilled in the art.

The photovoltaic module comprises a cell piece and an encapsulation layer, wherein the encapsulation layer is used for encapsulating and protecting the cell piece. The encapsulation layer generally refers to a back plate, a cover plate or an adhesive film between the battery piece and the back plate and between the battery piece and the cover plate.

In the production process of the photovoltaic module, the packaging layer is laid outside the cell slice to form a lamination part. After the laminating piece is heated by the laminating machine, the adhesive film is melted, so that the positions of the battery piece, the back plate and the cover plate are relatively fixed, and the photovoltaic module is difficult to disassemble. In other words, the photovoltaic module after lamination is difficult to perform the related repair operation of the cell. In view of this, before lamination, the to-be-laminated member needs to be subjected to strict quality control, and the to-be-laminated member with defects of the cell pieces is inspected and repaired to ensure the quality of the photovoltaic module.

The existing process repair comprises cell string repair and lamination repair, a welding belt and a cell sheet are welded by a stringer to form a cell string, and then the cell string is judged and detected by AI, a person skilled in the art generally refers to the substandard cell string as an NG string, the string repair is needed, the qualified cell string is referred as an OK string, and after the OK string is processed by a typesetter, a stitch welder, an adhesive tape pasting machine, secondary laying and other processes, if the process is poor, the cell string enters the lamination repair after the lamination EL and VI detection.

When the battery piece of the lamination piece is repaired, at least one packaging layer in the lamination piece needs to be lifted. For example, the back plate or the cover plate is lifted independently, or the back plate and the adhesive film are lifted synchronously, or the cover plate and the adhesive film are lifted synchronously. In the related art, the packaging layers are manually moved by workers, and due to manual uncontrollable factors, the problems of offset, poor string spacing, adhesive film turnover, bus bar turnover and the like are easily caused among the packaging layers or between the packaging layers and the battery pieces, so that the photovoltaic module is damaged or even scrapped. Moreover, the battery piece is very fragile, and improper operation of workers can cause additional breakage of the battery piece, so that the loss of the process fragment rate is increased. Moreover, the structure and the function of the existing repair workbench are simpler, a component for effectively fixing and synchronously lifting the back plate and the adhesive film is absent, two workers generally perform manual operation, uncontrollable factors are more, the repair success rate of the photovoltaic module is directly influenced, and the actual use effect is poor.

In order to solve the problems in the related art, as shown in fig. 1, an embodiment of the present invention provides a tool for repairing a laminate, including a bearing assembly 1, a lifting driving assembly 2 and a clamping assembly 3. Wherein, the bearing assembly 1 is provided with a bearing surface for bearing a to-be-laminated piece. The lifting driving assembly 2 is disposed on the bearing assembly 1, and the lifting driving assembly 2 has a lifting end capable of moving close to and away from the bearing surface. The clamping assembly 3 is arranged at the lifting end of the lifting driving assembly 2, and the clamping assembly 3 is used for clamping the outer edge of at least one packaging layer in the lamination part to be treated.

Adopt above-mentioned technical scheme under the circumstances, the embodiment of the utility model provides a treat that lamination piece reprocesses and use frock includes carrier assembly 1, lift drive assembly 2 and centre gripping subassembly 3, and carrier assembly 1 has and is used for bearing the loading end of treating the lamination piece, and lift drive assembly 2 has the lift end that the loading end is close to and keeps away from relatively. The clamping assembly 3 is arranged at the lifting end of the lifting driving assembly 2, the clamping assembly 3 can move towards the direction close to and away from the bearing surface under the driving of the lifting driving assembly 2, and the clamping assembly 3 is used for clamping the outer edge of at least one layer of packaging layer in the lamination piece. When the clamping assembly 3 clamps at least one layer of packaging layer in the lamination piece, the at least one layer of packaging layer in the lamination piece can move towards the direction close to and far away from the bearing surface under the driving of the lifting driving assembly 2. When at least one layer of packaging layer in the to-be-laminated part moves towards the direction far away from the bearing surface, at least one layer of packaging layer of the to-be-laminated part can be directly lifted, and a worker can conveniently maintain the battery piece of the to-be-laminated part. Need not the manual contact encapsulated layer, and need not to pull along the horizontal direction, when the encapsulated layer that is uplifted is more than the one deck, can not appear the relative movement phenomenon between the encapsulated layer that is uplifted, effectively avoid staff's improper operation to lead to by the skew appearing between the encapsulated layer that is uplifted, and then avoid the cluster interval bad, the glued membrane turns over a book, the busbar turns over a scheduling problem, promotes photovoltaic module's yield. Moreover, when the lifted packaging layer moves towards the direction close to the bearing surface, the lifted packaging layer descends according to the lifted route when descending, namely the lifted packaging layer returns to the original route, the lifted packaging layer can be accurately placed on the battery piece according to the original position, after the lifted packaging layer is re-laid on the battery piece, the phenomenon of left-right or front-back deviation with the battery piece cannot occur, and the re-lamination time after the laminated piece is maintained is saved. In addition, the cooperation of the bearing assembly 1, the lifting driving assembly 2 and the clamping assembly 3 is adopted to lift at least one packaging layer in the lamination piece, so that the labor force of workers can be saved.

It should be noted that, the clamping assembly 3 can clamp at least one packaging layer of the to-be-laminated member, and the clamped packaging layer is lifted under the driving of the lifting driving assembly 2, so that at least one packaging layer of the to-be-laminated member is far away from the battery piece, and an operator can conveniently maintain the to-be-laminated member comprehensively. The clamping assembly 3 is capable of clamping at least one encapsulation layer of the laminate to be laminated and lifting the clamped encapsulation layer. For example, when the back plate is placed on the bearing surface in an upward manner, the back plate can be lifted independently, or the back plate and the adhesive film in contact with the back plate can be lifted synchronously; when the cover plate is placed on the bearing surface upwards, the cover plate can be lifted independently or the cover plate and the adhesive film in contact with the cover plate can be lifted synchronously. Of course, when the clamping assembly 3 simultaneously lifts the cover plate and the adhesive film or the back plate and the adhesive film synchronously, the battery plate can be conveniently maintained by workers. When the clamping component 3 lifts the cover plate or the back plate, the worker can adjust the adhesive film so as to prevent the adhesive film from being folded. When the front side of the cell needs to be maintained, the photovoltaic module is placed on the bearing surface of the bearing module 1 with the front side facing upwards. The clamping assembly 3 simultaneously clamps the cover plate and the adhesive film and lifts the cover plate and the adhesive film under the driving of the lifting driving assembly 2. When the back of the cell needs to be maintained, the back of the photovoltaic module is placed upwards on the bearing surface of the bearing module 1. The clamping assembly 3 simultaneously clamps the back plate and the adhesive film and lifts the back plate and the adhesive film under the driving of the lifting driving assembly 2.

In the process of laminating and composing the battery piece, margins are reserved between the edge of the back plate and the edge of the adhesive film and between the edge of the adhesive film and the edge of the battery piece, the clamping component 3 supports and clamps the outer edge of at least one packaging layer in the to-be-laminated piece, and during actual clamping, the clamping component 3 clamps the four corners of the packaging layer at the margin positions. Need not the level and pull, need not to remove glued membrane or backplate alone, backplate and glued membrane do not have relative movement risk to produce skew, cluster interval is bad, the glued membrane turns over a book, the busbar turns over a scheduling problem between the encapsulation layer, makes photovoltaic module impaired even scrap. The damage of the battery piece caused by improper operation of workers can be effectively avoided, and the yield of the photovoltaic module is improved.

As a possible implementation manner, the clamping assembly 3 is rotatably connected to the lifting end of the lifting driving assembly 2, and the clamping assembly 3 has at least a clamping position and a releasing position relative to the bearing surface. In the clamping position, the clamping end of the clamping assembly 3 faces the center of the bearing surface, and the clamping assembly 3 is positioned right below or above the packaging layer to be clamped, so that the clamping end of the clamping assembly 3 can clamp at least one packaging layer of the packaging layer to be laminated. In the release position, the clamping ends of the clamping assemblies 3 are far away from the center of the carrying surface, and the packaging layer to be laminated can be released.

Therefore, the clamping assembly 3 is rotatably connected to the lifting end of the lifting driving assembly 2, so that the clamping assembly 3 can rotate from the clamping position to the releasing position relative to the bearing surface. As shown in fig. 6, the clamping assembly 3 is in the clamping position, and the clamping end of the clamping assembly 3 faces the center of the carrying surface, so that the clamping assembly 3 clamps at least one packaging layer to be laminated. After the clamping assembly 3 places the clamped packaging layer on the bearing surface, the clamping assembly 3 is rotated, so that the clamping end of the clamping assembly 3 is far away from the center of the bearing surface, the clamping assembly 3 is in a release position, and the packaging layer clamped by the clamping assembly 3 is placed on the bearing surface. It should be noted that the clamping end of the clamping assembly 3 is far away from the carrying surface, i.e. the clamping end is not located right above or right below the packaging layer after rotating a certain angle, as shown in fig. 7. When the clamping is needed, the clamping assembly 3 rotates to the clamping position around the lifting end of the lifting driving assembly 2, and when the clamping is not needed, the clamping assembly 3 rotates to the releasing position from the clamping position around the lifting end of the lifting driving assembly 2, so that the laminating work of the laminating piece is not influenced by the clamping assembly 3.

The holding end of the holding member 3 is an end of the holding member 3 capable of holding the package layer. The clamping end of the clamping assembly 3 faces the carrying surface, in particular, when the clamping assembly 3 is required to clamp the encapsulation layer, the clamping end of the clamping assembly 3 faces the to-be-laminated piece.
