Description

Technical Field

[0001] The invention belongs to the technical field of photovoltaic assembly production, and in particular relates to a device and method for fully automatic bonding and glazing of reflective films between battery sheets. Background Art

[0002] As a clean and renewable energy source, solar energy can be efficiently converted into electrical energy, which not only reduces dependence on non-renewable energy sources such as oil and coal, but also reduces environmental pollution and ecological damage. Therefore, how to improve the power generation capacity of photovoltaic modules has always been the direction of continuous research in the photovoltaic industry.

[0003] In the existing photovoltaic module production, one method used during the second glass bonding is to screen print white porcelain strips on the glass. After the glass bonding, the white porcelain strips are located at the gaps between the cells and the cell strings, so that the light energy irradiated at the gaps between the cell modules is reflected to the glass plate, and then reflected to the cell modules through the glass plate, so as to fully utilize the light energy at the gaps between the cell modules and improve the power generation. However, screen printing white porcelain strips on the glass will make the glass easy to crack and will also easily cause the cell to crack.

[0004] Patent CN220744586U in the prior art discloses a high-beat flexible double-glass assembly laminating device, which includes a first conveyor line for conveying a glass assembly, a flipping station, an intermediate buffer station and a glass laminating station arranged in sequence along the first conveyor line, a second conveyor line located above the first conveyor line for conveying two glasses, a first conveying mechanism for conveying materials between the flipping station and the intermediate buffer station, and a second conveying mechanism for conveying materials between the intermediate buffer station and the glass laminating station; when laminating, a glass assembly moves to the glass laminating station with the first conveyor line, and the second glass moves with the second conveyor line through the gap film pasting device to complete the gap reflective film pasting after the previous process is completed. Then, it moves to the flipping station, and cooperates with the external flipping mechanism at the flipping station to perform a 180° flip, so that the surface of the side pasted with the gap film faces downward; then the first conveying mechanism conveys the second glass from the flipping station to the intermediate buffer station; and the second conveying mechanism conveys the second glass from the intermediate buffer station to the laminating station for laminating operation.

[0005] The gap film pasting equipment used in the above-mentioned laminating equipment, such as the patent CN117727818B in the prior art, discloses an automatic film pasting equipment for the gap reflective film of photovoltaic cell modules, which pastes a number of reflective films on the second glass of the glass to be combined corresponding to the gap position of the cell string, and then the second glass pasted with the reflective film is transported to the glass combining station, and then flipped 180° for glass combining operation. Although this equipment provides a new way to set the reflective film, avoiding the problem that the original screen printing method easily causes glass bursting, the second glass needs to be flipped 180° when the glass is combined. On the one hand, the flipping process requires a large space, and on the other hand, there is a large risk of falling during the flipping action. Therefore, the flipping process needs to be carried out slowly, which reduces the efficiency of the glass combining operation; in addition, there is a risk of the reflective film loosening, falling off or shifting during the flipping process of the second glass, which affects the product quality; this film pasting equipment can only paste the reflective film in one direction, and cannot fully cover all the gaps in the photovoltaic module, and there are process limitations.

[0006] Therefore, it is necessary to provide a new fully automatic bonding and glass bonding equipment and method for reflective film between battery cells to solve the above technical problems. Summary of the invention

[0078] Please refer to Figure 1-Figure 14The present embodiment further provides a fully automatic bonding and glazing device 100 for reflecting film between battery cells, which realizes the fully automatic bonding and glazing method for reflecting film between battery cells, and comprises two glass feeding stations 10 arranged side by side, a short side reflecting film bonding station 20 and a long side reflecting film bonding station 30, a glazing station 40 arranged beside the long side reflecting film bonding station 30, a short side reflecting film bonding unit 1 arranged at the short side reflecting film bonding station 20, a long side reflecting film bonding unit 2 arranged at the long side reflecting film bonding station 30, a short side reflecting film feeding unit 3 located beside the short side reflecting film bonding station 20, a long side reflecting film feeding unit 4 located beside the long side reflecting film bonding station 30, a first conveying mechanism 5 whose transfer range covers the section between the two glass feeding stations 10 and the long side reflecting film bonding station 30, and a second conveying mechanism 6 whose transfer range covers the section between the long side reflecting film bonding station 30 and the glazing station 40.

[0079] The second glass loading station 10, the short side reflective film pasting station 20 and the long side reflective film pasting station 30 are arranged in sequence from left to right, and the long side reflective film feeding unit 4 is arranged on the right side of the long side reflective film pasting station 30. In this embodiment, the glass joining station 40 is arranged at the rear side of the long side reflective film pasting station 30, the short side reflective film feeding unit 3 is arranged at the front side of the short side reflective film pasting station 20, and the supporting gantry of the first conveying mechanism 5 is arranged at the front side of the short side reflective film pasting station 20. In other embodiments, the glass joining station 40 can also be arranged at the front side of the long side reflective film pasting station 30, and the short side reflective film feeding unit 3 is arranged at the rear side of the short side reflective film pasting station 20, and the supporting gantry of the first conveying mechanism 5 is arranged at the rear side of the short side reflective film pasting station 20.

[0080] Since the short-side reflective film and the long-side reflective film are set in different directions and are distributed vertically and orthogonally, in order to prevent the glass from rotating as much as possible and improve the efficiency of glass transfer, the feeding direction of the short-side reflective film and the feeding direction of the long-side reflective film are distributed vertically, avoiding the adjustment of the direction of the reflective film while also avoiding the adjustment of the direction of the glass.

[0081] In addition, in other embodiments, the position of the glass joining station 40 can also be swapped with the second glass loading station 10, that is, the glass joining station 40, the short-side reflective film pasting station 20 and the long-side reflective film pasting station 30 are arranged in sequence from left to right, and the second glass loading station 10 is arranged at the front side or the rear side of the long-side reflective film pasting station 30. The second conveying mechanism 6 conveys the second glass at the second glass loading station 10 to the long-side reflective film pasting station 30. After the pasting of the long-side reflective film is completed, it is conveyed to the short-side reflective film pasting station 20 by the first conveying mechanism 5. After the pasting of the short-side reflective film is completed, it is conveyed to the glass joining station 40 by the first conveying mechanism 5 for glass joining.

[0082] In this embodiment, the film after the roll of reflective film is unfolded is called "reflective film", the sheet structure cut into a set length of "reflective film" is called "sheet reflective film", and the strip structure cut into a plurality of strips with a set width is called "strip reflective film".

[0083] The short-edge reflective film feeding unit 3 cuts the roll of reflective film into slender strips of reflective film of a set width, and includes a roll feeding mechanism 31, a film feeding mechanism 32, a first cutting mechanism 33 for cutting the reflective film output by the film feeding mechanism 32 into sheet-shaped reflective film, a receiving and conveying platform 34 located at the output side of the film feeding mechanism 32 and receiving the sheet-shaped reflective film, a strip-cutting receiving platform 35 located at the output side of the receiving and conveying platform 34, a first adsorption and conveying mechanism 36 for conveying the sheet-shaped reflective film from the receiving and conveying platform 34 to the strip-cutting receiving platform 35, a second cutting mechanism 37 for cutting the sheet-shaped reflective film on the strip-cutting receiving platform 35 into a plurality of strip-shaped reflective film, and a second adsorption and conveying mechanism 38 for adsorbing and conveying the plurality of strip-shaped reflective film to the short-edge reflective film pasting unit 1. Since the short-side reflective film located in the middle position needs to avoid the leads extending upward to facilitate the subsequent installation of the junction box, the reflective film corresponding to the lead extending position needs to be punched out with avoidance holes at the corresponding positions. Based on this requirement, the short-side reflective film feeding unit 3 of this embodiment also includes a punching mechanism 39, which is located between the coil feeding mechanism 31 and the film feeding mechanism 32.

[0084] The coil loading mechanism 31 is mainly used to realize the replacement and unwinding of the coil, and its structure can adopt the structure in the prior art, which will not be described in detail in this embodiment.

[0085] The film feeding mechanism 32 is mainly used for accurately conveying the reflective film to ensure the output length. Its structure can adopt the material roll feeding structure in the prior art, which will not be described in detail in this embodiment.

[0086] The first cutting mechanism 33 is arranged between the film feeding mechanism 32 and the material receiving and conveying platform 34, and includes a pressing module 331 for pressing the reflective film and a cutting module 332 for cutting the reflective film. The pressing module 331 includes a pair of pressure strips 3311 for pressing the two sides of the cutting line of the reflective film and a cylinder 3312 for driving the pair of pressure strips 3311 to move up and down. The cutting module 332 includes a first motor 3321, a first slide plate 3322 driven by the first motor 3321 to move horizontally perpendicular to the conveying direction of the reflective film, a second motor 3323 fixed on the first slide plate 3322, and a first blade 3324 driven by the second motor 3323 to rotate and extending between the two pressure strips 3311. The film feeding mechanism 32 outputs a reflective film of a set length, a pair of pressure strips 3311 presses the reflective film, the first motor 3321 drives the first blade 3324 to move from one end of the reflective film to the other end, and at the same time the second motor 3323 drives the first blade 3324 to rotate and roll cut, thereby cutting the reflective film into sheet-shaped reflective film.

[0087] The receiving and conveying platform 34 includes a first receiving plate 341 and a conveying module 342 embedded in the surface of the first receiving plate 341. In order to prevent the reflective film from being unevenly unfolded, a plurality of exhaust holes 3411 are provided on the first receiving plate 341 to improve the fit between the reflective film and the first receiving plate 341. The conveying module 342 is used to convey, unfold and flatten the reflective film output by the film feeding mechanism 32.

[0088] The strip cutting receiving platform 35 comprises a second receiving plate 351 , and a plurality of strip-shaped through grooves 352 are arranged on the second receiving plate 351 .

[0089] The second cutting mechanism 37 includes a third motor 371, a second slide plate 372 driven by the third motor 371 to move horizontally perpendicular to the conveying direction of the reflective film, a rotating shaft 373 rotatably arranged on the second slide plate 372, a plurality of second blades 374 fixed on the rotating shaft 373 and extending into the strip-shaped through groove 352, and a fourth motor 375 fixed on the second slide plate 372 and driving the rotating shaft 373 to rotate. When the sheet reflective film is placed on the second receiving plate 351, the second adsorption and conveying mechanism 38 is pressed against the sheet reflective film, and the third motor 371 drives the second blade 374 to move from one end of the sheet reflective film to the other end. At the same time, the fourth motor 375 drives the second blade 374 to roll and cut, so as to cut the sheet reflective film into a plurality of strip reflective films.

[0090] The transfer range of the first adsorption conveying mechanism 36 covers the material receiving and conveying platform 34 and the strip receiving and conveying platform 35, and includes a fifth motor 361, a first beam 362 driven by the fifth motor 361 to move parallel to the conveying direction of the reflective film, a sixth motor 363 fixed on the first beam 362, and an adsorption plate 364 driven by the sixth motor 363 to move up and down.

[0091] The second adsorption and conveying mechanism 38 includes a seventh motor 381, a second beam 382 driven by the seventh motor 381 to move parallel to the conveying direction of the reflective film, an eighth motor 383 fixed on the second beam 382, ​​a bracket 384 driven by the eighth motor 383 to move up and down, and a variable-distance adsorption module 385 arranged on the bracket 384.

[0092] After the sheet reflective film is cut into strip reflective film, the gap between two adjacent strip reflective film is very small, almost no gap, while there is a certain gap between the carrier strips used to receive the strip reflective film in the short-side reflective film pasting unit 1. Therefore, after a group of strip reflective film is sucked from the strip cutting and receiving platform 35, the spacing needs to be adjusted before it can be placed on the carrier strip of the short-side reflective film pasting unit 1.

[0093] In this embodiment, the variable pitch adsorption module 385 includes a ninth motor 3851 fixed on the bracket 384, and a plurality of adsorption strips 3852 driven by the ninth motor 3851 to achieve pitch change. There are many structures in the prior art that realize the variable pitch function, such as a magnetic suspension structure, a rotating rod structure with a threaded groove, a flexible connector sliding structure, or a movable connector sliding structure, etc., which are not limited in this embodiment. In this embodiment, the outermost adsorption strip 3852 is fixedly arranged, and the outermost adsorption strip 3852 is moved closer to or away from the fixed adsorption strip 3852 by the ninth motor 3851. A plurality of middle adsorption strips located between the outermost adsorption strips are slidably arranged on the slide rail, and two adjacent adsorption strips 3852 are connected together by a flexible connector. When the ninth motor 3851 drives the outermost adsorption strip on the other side to move closer to the outermost adsorption strip on the one side, it will squeeze the middle adsorption strips to move closer to each other at the same time, so that all the adsorption strips 3852 are in a close state, and there is an avoidance gap (not marked in the figure) between the lower surfaces of two adjacent adsorption strips 3852 for the second blade 374 to extend into. When all the adsorption strips 3852 are in a close state, they are pressed against the second receiving plate 351, and the avoidance gap corresponds to the position of the strip-shaped through groove 352. After the second blade 374 cuts the sheet-like reflective film into a plurality of strips of reflective film, a strip of reflective film is formed under each adsorption strip 3852, and then it is sucked out by the adsorption strip 3852; when the ninth motor 3851 drives the outermost adsorption strip on the other side to move away from the outermost adsorption strip in the opposite direction, under the joint action of the flexible connector, all the middle adsorption strips are pulled apart to a pulled apart state, and in this pulled apart state, all the strips of reflective film are placed on the carrier strip of the short-side reflective film pasting unit 1.

[0094] In the structural description of the short-edge reflective film feeding unit 3, "the conveying direction of the reflective film" refers to the conveying direction of the short-edge reflective film.

[0095] The short-side reflective film pasting unit 1 is mainly used to receive a plurality of reflective film strips at the material receiving position, and then spread them out in the short-side reflective film pasting station 20 area, and the unfolded reflective film strips correspond to the positions to be pasted on the second glass, and then pasted on the second glass. The short-side reflective film pasting unit 1 includes a reflective film receiving and transferring mechanism 11 and a hot spot mechanism 12.

[0096] The reflective film receiving and transferring mechanism 11 includes a plurality of carrier bars 111 and a driving module 112 for driving all the carrier bars 111 to switch between a closed state and an extended state. There are many structures for realizing the variable pitch function in the prior art, such as a magnetic suspension structure, a rotating rod structure with a threaded slide groove, a flexible connector sliding structure or a movable connector sliding structure, etc. This embodiment does not limit the mechanism of the driving module 112 driving the carrier bars 111 to realize the pitch change.

[0097] The hot stamping mechanism 12 includes a plurality of hot stamping components 121 located at the short-side reflective film pasting station 20 and below the carrier strip 111 , and a lifting mechanism 122 for driving the hot stamping components 121 to move up and down.

[0098] In this embodiment, the carrier bars 111 include a first carrier bar 1111 and a second carrier bar 1112 located at the outermost sides, and a plurality of third carrier bars 1113 located between the first carrier bar 1111 and the second carrier bar 1112. All the carrier bars 111 are slidably disposed on a plurality of pairs of slide rail modules 113, and the plurality of pairs of slide rail modules 113 are used to provide strong and reliable support to the two end positions and the middle section of the carrier bars 111. The driving module 112 drives the first carrier bar 1111 and the second carrier bar 1112 to move horizontally in parallel with the conveying direction of the short-side reflective film. A flexible connecting belt 114 is arranged between two adjacent carrier bars 111. When the first carrier bar 1111 and the second carrier bar 1112 are driven to move closer, the third carrier bar 1113 in the middle is compressed, so that all the carrier bars 111 are brought together and are in a close state; when the first carrier bar 1111 and the second carrier bar 1112 are driven to open, under the joint action of the flexible connecting belt 114, the third carrier bar 1113 in the middle is pulled together and is in an extended state.

[0099] The upper surface of the carrier strip 111 is provided with a bearing groove 1114 for bearing the strip reflective film, and the bottom of the bearing groove 1114 is provided with a plurality of through holes 1115 penetrating downward, and the plurality of through holes 1115 are spaced apart along the extending direction of the carrier strip 111. When the plurality of carrier strips 111 are unfolded, their upper surfaces jointly form a supporting platform for supporting the second glass. The hot-pressing assembly 121 is aligned with the through holes 1115, and the hot-pressing assembly 121 is driven by the lifting mechanism 122 to move upward through the through holes 1115 to paste the strip reflective film in the bearing groove 1114 to the lower surface of the second glass, thereby completing the automatic pasting of all the short-side reflective films.

[0100] Each short-side reflective film is a single-strip structure without interruption in the middle, but the long-side reflective film needs to avoid the bus bar and the junction box installation position in the middle area, so each long-side reflective film includes two collinear reflective films. Based on this, in this embodiment, the long-side reflective film feeding unit 4 includes two first submodules 41, and the structure of the first submodule 41 is basically the same as that of the short-side reflective film feeding unit 3, the difference is that: since the long-side reflective film does not need to avoid the extended lead, the first submodule 41 is not provided with a punching mechanism 39. In other embodiments, if the long-side reflective film needs to be punched, a punching mechanism 39 can also be configured, which is mainly flexibly configured according to functional requirements.

[0101] Correspondingly, the long side reflective film pasting unit 2 includes two second submodules 21, and the second submodule 21 has the same structure as the short side reflective film pasting unit 1. In order to be suitable for pasting long side reflective films with different intermediate spacings, the long side reflective film pasting unit 2 also includes a spacing adjustment mechanism 22 for driving the two second submodules 21 to adjust the spacing.

[0102] The first transport mechanism 5 includes a first gantry 51 and two first transport modules 52 movably arranged on the first gantry 51. The first transport module 52 can move left and right and up and down. The movable end of the first transport module 52 is provided with a first suction cup assembly, and the glass surface is adsorbed by the first suction cup assembly. The two first transport modules 52, one of which is responsible for the glass transport between the second glass feeding station 10 and the short side reflective film pasting station 20, and the other is responsible for the glass transport between the short side reflective film pasting station 20 and the long side reflective film pasting station 30.

[0103] The second transport mechanism 6 includes a second gantry 61 and a second transport module 62 movably arranged on the second gantry 61. The second transport module 62 is configured with forward and backward movement functions and up and down movement functions. A second suction cup assembly is arranged at the movable end of the second transport module 62, and the glass surface is adsorbed by the second suction cup assembly to perform glass closing operations.

[0104] The glass can be transported to the second glass loading station 10 through a glass conveyor line, and then the position is corrected by a surrounding correction mechanism.

[0105] The glass combining station 40 can be used to convey the laminated parts to the station through the glass conveyor line, and the glass can be corrected around the four sides by the four-side correction mechanism during the glass combining process to ensure the accuracy of the glass combining. The second suction cup assembly can also be equipped with a 360° adaptive fine-tuning function, such as the "second conveying mechanism" disclosed in the patent CN220744586U in the prior art and a conveying mechanism with a universal floating function disclosed in the patent CN220744585U.

[0106] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, all of which fall within the protection scope of the present invention.
