[0002] Photovoltaic modules are important products in the photovoltaic power generation field, used to convert solar energy into electrical energy. Photovoltaic modules are composed of photovoltaic glass, solar cells mounted on the photovoltaic glass, and a film covering the solar cells. During the production of photovoltaic modules, a gluing device is required to apply glue to the four sides of the photovoltaic module, thereby applying sealant to the edges where the film and photovoltaic glass come into contact. In the prior art, the photovoltaic module gluing process involves securing the photovoltaic glass to a suction cup pad using a suction cup, and then applying glue to the four edges of the photovoltaic glass using a single gun head. The gluing process is achieved by moving the gluing head relative to the four sides of the photovoltaic module. The photovoltaic module remains stationary during this process. After the entire gluing process is completed, the photovoltaic module is transported to the subsequent workstation.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. 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 making creative efforts are within the scope of protection of the present invention.

[0035] like Figures 1 to 9As shown, a photovoltaic module edge coating device of this embodiment is used for coating glue on the edges of the photovoltaic module 20, including a transmission unit 1 for transmitting the photovoltaic module 20 and a coating unit 2 for coating glue on the photovoltaic module 20, the transmission unit 1 includes a correction and positioning module 3, a linear transmission module 4 extending laterally along the conveying direction of the photovoltaic module 20 and a mobile transmission module 5 capable of driving the photovoltaic module 20 to move laterally and longitudinally, the linear transmission module 4 enables the correction and positioning module 3 to correct different photovoltaic modules 20 to a standard position during the conveying process of the photovoltaic module 20, the linear transmission module 4 is used to convey the photovoltaic module 20 in a straight line along the conveying direction. In this embodiment, the conveying direction of the photovoltaic module 20 is Figure 2 The width direction of the paper is shown in FIG. Of course, in other optional embodiments, the transport direction of the photovoltaic modules 20 can also be adjusted according to actual needs. The mobile transport module 5 enables the photovoltaic modules 20 to move in the transverse and longitudinal directions relative to the linear transport module 4. The gluing unit 2 includes a first gluing module 21 and a second gluing module 22, which are arranged in sequence along the transport direction of the photovoltaic modules 20. The first gluing module 21 and the second gluing module 22 can respectively apply glue to the photovoltaic modules 20.

[0036] In this embodiment, the gluing is completed by the following steps:

[0037] S1: The current photovoltaic component 20 moves with the linear transmission module 4 and is completely placed on the linear transmission module 4, so that the current photovoltaic component 20 can be gradually transported from the outside of the linear transmission module 4 to the linear transmission module 4, so that the current photovoltaic component 20 can be gradually and completely transported to the coating equipment.

[0038] S2: The correction positioning module 3 performs visual inspection and correction positioning on the current photovoltaic component 20. The actual state of the current photovoltaic component 20 can be obtained through visual inspection, and the position of the current photovoltaic component 20 can be corrected through correction positioning, so that different photovoltaic components 20 can have the same position relative to the linear transmission module 4 after correction.

[0039] S3: The mobile transmission module 5 drives the current photovoltaic component 20 to move so that one end of the front edge of the current photovoltaic component 20 is located under the first gluing module 21. During this process, the mobile transmission module 5 drives the current photovoltaic component 20 to move longitudinally and transversely relative to the linear transmission module 4, so that the mobile transmission module 5 drives the current photovoltaic component 20 to change position.

[0040] S4: The current photovoltaic component 20 moves laterally along with the mobile transmission module 5 relative to the first gluing module 21 to apply glue to one long side of the current photovoltaic component 20 and finally make the first gluing module 21 and the second gluing module 22 located at both ends of the long side respectively, so that the first gluing module 21 moves relative to the current photovoltaic component 20 to complete the gluing of one long side of the photovoltaic component 20.

[0041] S5: The first gluing module 21 and the second gluing module 22 both apply glue to the two short sides of the current photovoltaic component 20 along the short side direction, so that the first gluing module 21 and the second gluing module 22 move relative to the current photovoltaic component 20, thereby completing the gluing of the two short sides of the photovoltaic component 20.

[0042] S6: The current photovoltaic component 20 moves laterally with the mobile transmission module 5 relative to the second gluing module 22 to apply glue to the other long side of the current photovoltaic component 20 and finally make the other end of the rear edge of the current photovoltaic component 20 located under the second gluing module 22 to complete the gluing of the current photovoltaic component 20. In this step, the relative movement between the second gluing module 22 and the current photovoltaic component 20 is used, and the gluing of the other long side of the current photovoltaic component 20 is completed in the process, and finally the other end of the rear edge of the current photovoltaic component 20 is located under the second gluing module 22, which makes it easier to apply glue to the next photovoltaic component 20.

[0043] By means of the above structure, the first gluing module 21 and the second gluing module 22 are used to jointly gluing the photovoltaic component 20, and the photovoltaic component 20 itself remains in a moving state during the gluing process, so that during the gluing process, the photovoltaic component 20 is gluing through the two gluing modules, thereby shortening the gluing time, and during the gluing process, one long side, two short sides and another long side are coated in sequence, thereby improving the utilization rate of the first gluing module 21 and the second gluing module 22, reducing the idle time of the gluing module, thereby improving the gluing efficiency, and reducing the unstable gluing caused by the long stop time of the first gluing module 21 or the second gluing module 22.

[0044] Specifically, the mobile transport module 5 includes a first transport assembly 41 located at the front end of the first gluing module 21 and a second transport assembly 42 located at the rear end of the second gluing module 22 in the transport direction of the photovoltaic modules 20. The first transport assembly 41 is used to transport the photovoltaic modules 20 into the coating equipment, while the second transport assembly 42 is used to transport the photovoltaic modules 20 after gluing, and gradually transport them to the outside of the coating equipment.

[0045] Through the above steps, the photovoltaic component 20 can be transported to the inside and outside of the coating equipment, so that the photovoltaic component 20 before gluing is transported to the inside of the coating equipment, and the photovoltaic component 20 after gluing is transported to the outside of the coating equipment.

[0046] Specifically, the correction and positioning module 3 includes a side push correction component 31 located on both sides of the first transmission component 41, a blocking component 32 located above the end of the first transmission component 41 adjacent to the first gluing module 21, a rear correction component 33 located at the end of the first transmission component 41 away from the first gluing module 21, and a visual component 34 for detecting the photovoltaic component 20 on the first transmission component 41.

[0047] Specifically, the correction and positioning module 3 includes a side-pushing correction component 31 located on both sides of the first transmission component 41, a blocking component 32 located above the end of the first transmission component 41 adjacent to the first gluing module 21, a rear correction component 33 located at the end of the first transmission component 41 away from the first gluing module 21, and a visual component 34 for detecting the photovoltaic component 20 on the first transmission component 41. The side-pushing correction component 31 is used to position the two sides of the photovoltaic component 20, the blocking component 32 is used to position the front end of the photovoltaic component 20, and the rear correction component 33 is used to position the rear end of the photovoltaic component 20. After the photovoltaic component 20 passes over the rear correction component 33, the rear correction component 33 is lifted and moved forward so that the two ends of the current photovoltaic component 20 are respectively abutted against the blocking component 32 and the rear correction component 33, thereby limiting the position of the photovoltaic component 20 in the conveying direction of the photovoltaic component 20 by the blocking component 32 and the rear correction component 33. It is worth noting that the steps of positioning the photovoltaic assembly 20 from both sides and in the conveying direction can be performed in a sequential order, and of course, can also be completed simultaneously.

[0048] In the initial state, the distance between the side-pushing and straightening assemblies 31 is greater than the width of the photovoltaic assembly 20, allowing the photovoltaic assembly 20 to pass through the area between the side-pushing and straightening assemblies 31 and be transported forward. The rear straightening assembly 33 is located below the first transmission assembly 41, allowing the photovoltaic assembly 20 to be transported over the rear straightening assembly 33, avoiding interference with the photovoltaic assembly 20 during transportation. The visual assembly 34 is used to perform incoming material detection on the photovoltaic assembly 20, allowing the visual assembly 34 to detect the incoming material of the photovoltaic assembly 20 located on the first transmission assembly 41, thereby detecting the position and status of the photovoltaic assembly 20.

[0049] By means of the above structure, the photovoltaic component 20 is positioned from both sides by the side push correction component 31, and the photovoltaic component 20 is positioned from the conveying direction in cooperation with the blocking component 32 and the rear correction component 33, thereby achieving the correction and positioning effect of the photovoltaic component 20 from both sides and front and back, so that different photovoltaic components 20 can have the same correction and positioning effect, and can avoid interference with the photovoltaic component 20 during the correction and positioning process, so that the correction and positioning process has higher stability.

[0050] Specifically, the side push correction component 31 includes a first side push correction module 311 and two second side push correction modules 312 respectively arranged on both sides of the first transmission component 41, wherein the first side push correction module 311 includes a first transverse movement module 3111 arranged along a direction perpendicular to the conveying direction of the photovoltaic component 20, and the first transverse movement module 3111 is connected to an elastic roller module 3112, so that the first transverse movement module 3111 can drive the elastic roller module 3112 closer to or away from the photovoltaic component 20. The second side-push correction module 312 includes a second transverse movement module 3121 arranged perpendicular to the conveying direction of the photovoltaic component 20. The second transverse movement module 3121 is connected to a rigid roller module 3122, so that the second transverse movement module 3121 can drive the rigid roller module 3122 closer to or away from the photovoltaic component 20. Preferably, the first side-push correction module 311 and the second side-push correction module 312 are arranged in an staggered manner, that is, the first side-push correction module 311 corresponds to the area between the two second side-push correction modules 312.

[0051] With the above structure, the first side push correction module 311 and the second side push correction module 312 jointly position the two sides of the photovoltaic component 20. During this process, the elastic roller module 3112 can buffer the photovoltaic component 20 when in contact, thereby protecting the photovoltaic component 20 during the positioning process. In addition, it also allows the force to be dispersed when positioning the two sides of the photovoltaic component 20, thereby avoiding the offset of the photovoltaic component 20 when positioning the two sides, thereby improving the stability of the photovoltaic component 20.

[0052] Specifically, the first transmission assembly 41 and the second transmission assembly 42 each include a plurality of conveyor belts 43 spaced apart perpendicular to the direction of transport of the photovoltaic assemblies 20. The plurality of conveyor belts 43 can simultaneously transport the photovoltaic assemblies 20 located thereon. The mobile transmission module 5 includes a first transport module 51 and a second transport module 52 that can move laterally and longitudinally between the first transmission assembly 41 and the second transmission assembly 42. In an initial state, the first transport module 51 and the second transport module 52 are both located below the first transmission assembly 41, thereby preventing the first transport module 51 and the second transport module 52 from interfering with the photovoltaic assemblies 20 during transport of the photovoltaic assemblies 20. The first transport module 51 and the second transport module 52 can each lift and absorb adjacent photovoltaic assemblies 20 and drive two adjacent photovoltaic assemblies 20 to move, thereby achieving the effect of the first transport module 51 and the second transport module 52 moving the current and next photovoltaic assemblies 20, respectively.

[0053] After driving the corresponding adsorbed photovoltaic assembly 20 to be positioned at the second transmission assembly 42 , the first transport module 51 or the second transport module 52 disconnects adsorption and returns to the initial position, thereby facilitating continuous transportation of subsequent photovoltaic assemblies 20 .

[0054] In this embodiment, the current photovoltaic assembly 20 and the next photovoltaic assembly 20 sequentially enter the first transport module 51. The current photovoltaic assembly 20 is lifted and adsorbed by the first transport module 51, and the photovoltaic assembly 20 is driven to move. Afterwards, the next photovoltaic assembly 20 is lifted and adsorbed by the second transport module 52. After the first transport module 51 drives the current photovoltaic assembly 20 to be positioned on the second transmission assembly 42, the first transport module 51 disconnects adsorption and returns to its initial position. The current photovoltaic assembly 20 is transported backward by the second transmission assembly 42. At the same time, the next photovoltaic assembly 20 serves as the current photovoltaic assembly 20 for subsequent steps. The first transmission assembly 41 lifts and adsorbs the photovoltaic assembly 20, which is now the next one, and drives the photovoltaic assembly 20 to move. Thus, the first transport module 51 and the second transport module 52 respectively drive the two adjacent photovoltaic assemblies 20 to move.

[0055] By using the above method, the adjacent photovoltaic components 20 are lifted and adsorbed by using the first transport module 51 or the second transport module 52 respectively, thereby driving the corresponding photovoltaic components 20 to move, so that multiple photovoltaic components 20 can be processed at the same time, thereby improving the efficiency of processing the photovoltaic components 20.

[0056] Specifically, the mobile transmission module 5 also includes a first auxiliary transport module 53 and a second auxiliary transport module 54 that can move horizontally and longitudinally between the first transmission component 41 and the second transmission component 42. The upper surfaces of the first auxiliary transport module 53 and the second auxiliary transport module 54 are respectively arranged corresponding to the two long sides of the photovoltaic component 20, so that the first auxiliary transport module 53 and the second auxiliary transport module 54 can support the long sides of the photovoltaic component 20 during the gluing process. Among them, the first auxiliary transport module 53 has a first adsorption transmission component 531 and a second adsorption transmission component 532 arranged in sequence along the front and back, and the second auxiliary transport module 54 has a third adsorption transmission component 541 and a fourth adsorption transmission component 542 arranged in sequence along the front and back. In the initial state, the first adsorption transmission component 531 and the third adsorption transmission component 541 are both located below the first transmission component 41, and the second adsorption transmission component 532 and the fourth adsorption transmission component 542 are both located below the glue coating unit 2, that is, in the conveying direction of the photovoltaic component 20, the second adsorption transmission component 532 is located in front of the first adsorption transmission component 531, and the fourth adsorption transmission component 542 is located in front of the third adsorption transmission component 541.

[0057] In an alternative embodiment:

[0058] The first adsorption and transmission component 531 and the first transport module 51 synchronously adsorb and lift the photovoltaic component 20 and drive the photovoltaic component 20 to move. During this process, the first adsorption and transmission component 531 adsorbs one long side of the photovoltaic component 20;

[0059] The first adsorption and transmission component 531 breaks the vacuum and separates from the photovoltaic component 20. The first adsorption and transmission component 531 returns to the initial state. The fourth adsorption and transmission component 542 lifts and adsorbs the photovoltaic component 20. The fourth adsorption and transmission component 542 and the first transport module 51 drive the photovoltaic component 20 to move toward the second transmission component 42.

[0060] The fourth adsorption and transmission component 542 breaks the vacuum and separates from the photovoltaic component 20, and the fourth adsorption and transmission component 542 returns to the initial state;

[0061] In another alternative embodiment:

[0062] The third adsorption and transmission component 541 and the second transport module 52 simultaneously adsorb and lift the photovoltaic component 20. During this process, the third adsorption and transmission component 541 adsorbs the other long side of the photovoltaic component 20.

[0063] The third adsorption and transmission component 541 breaks the vacuum and detaches from the photovoltaic component 20. The third adsorption and transmission component 541 returns to its initial state. The second adsorption and transmission component 532 lifts and adsorbs the photovoltaic component 20. The second adsorption and transmission component 532 and the second transport module 52 drive the photovoltaic component 20 to move toward the second transmission component 42.

[0064] The third adsorption and transmission component 541 breaks the vacuum and separates from the photovoltaic component 20 , and the third adsorption and transmission component 541 returns to the initial state.

[0065] It is worth noting that, since the first transport module 51 and the second transport module 52 respectively drive the two adjacent photovoltaic modules 20 to move, the steps in the above two embodiments are performed in sequence.

[0066] By means of the above method, the first auxiliary transport module 53 and the second auxiliary transport module 54 can cooperate with the first transport module 51 and the second transport module 52 to drive the movement of the photovoltaic component 20, and in this process respectively support the long side and the other long side of the photovoltaic component 20, thereby making the photovoltaic component 20 have better stability during the movement and gluing process.

[0067] Specifically, the upper surfaces of the first conveying module 51, the second conveying module 52, the first auxiliary conveying module 53 and the second auxiliary conveying module 54 all have multiple suction cups 55 arranged in sequence along their extension direction to adsorb the photovoltaic component 20 after contacting the photovoltaic component 20.

[0068] Specifically, the first transport module 51, the second transport module 52, the third transport module, and the fourth transport module all have a transverse rack 8 that is fixed and extends laterally along the transport direction of the photovoltaic module 20, a bevel gear 9 that meshes with the transverse rack 8, and a transport structure 10 connected to the bevel gear 9. The transverse rack 8 is used to guide the bevel gear 9 and the transport structure 10. The bevel gear 9 is used to drive the transport structure 10 to move relative to the transverse rack 8. The transport structure 10 is used to drive the photovoltaic module 20 thereon to move. The transport structure 10 includes:

[0069] The bottom plate 101 is connected to the bevel gear 9 so that the bottom plate 101 can move laterally with the bevel gear 9 relative to the transverse rack 8.

[0070] The linear drive unit 102 is located on the base plate 101 and extends in the same direction as the transverse rack 8. In this embodiment, the linear drive unit 102 is a screw motor. Of course, in other optional embodiments, the actual structure of the eastern part of the linear area can be adjusted according to actual needs.

[0071] The guide rail portion 103 is located on the bottom plate 101 and extends in the same direction as the transverse rack 8 . The guide rail portion 103 is provided corresponding to the linear drive portion 102 .

[0072] The guide rail slider 104 is slidably connected to the guide rail portion 103, and the guide rail slider 104 is connected to the linear drive portion 102, so that the linear drive portion 102 can drive the guide rail slider 104 and the guide rail portion 103 to generate relative movement.

[0073] The connecting rod portion 105 has two ends rotatably connected to the guide rail slider 104 and the vacuum suction plate respectively. The connecting rod portion 105 can have an angle with the horizontal direction, so that the connecting rod portion 105 changes the longitudinal distance between the guide rail slider 104 and the vacuum suction plate during the process of changing the angle with the horizontal direction.

[0074] The linear guide portion 106 extends longitudinally, and the two ends of the linear guide portion 106 are respectively connected to the base plate 101 and the vacuum suction plate. In this embodiment, the linear guide portion 106 is a linear bearing. Of course, in other optional embodiments, the actual structure of the linear guide portion 106 can be adjusted according to actual needs.

[0075] In this embodiment, when the photovoltaic assembly 20 is located behind the vacuum suction plate, the bevel gear 9 rotates to move relative to the transverse rack 8, thereby driving the transport structure 10 to move transversely in the direction of movement of the photovoltaic assembly 20, so that the photovoltaic assembly 20 can achieve a transverse movement effect. The linear drive portion 102 drives the guide rail slider 104 and the guide rail portion 103 to produce relative movement, thereby causing the connecting rod portion 105 to change its angle with the transverse direction, thereby changing the longitudinal distance between the guide rail slider 104 and the vacuum suction plate. During this process, the linear guide portion 106 plays a longitudinal guiding role, thereby preventing movement other than the longitudinal direction between the bottom plate 101 and the vacuum suction plate, thereby achieving a longitudinal movement effect of the photovoltaic assembly 20.

[0076] By means of the above structure, the bevel gear 9 rotates relative to the transverse rack 8 and the linear drive part 102 drives the guide rail slider 104, so that the photovoltaic component 20 located on the vacuum suction cup 55 can achieve horizontal and vertical movement effects respectively, thereby ensuring that the photovoltaic component 20 has a relatively stable movement effect and improving the stability of the entire structure.

[0077] Specifically, the upper surfaces of the first conveying module 51, the second conveying module 52, the first auxiliary conveying module 53 and the second auxiliary conveying module 54 all have a plurality of suction cups 55 arranged in sequence along their extension direction, so as to adsorb the photovoltaic component 20 after contacting the photovoltaic component 20, so that the first conveying module 51, the second conveying module 52, the first auxiliary conveying module 53 and the second auxiliary conveying module 54 have a better connection effect with the photovoltaic component 20, and damage to the photovoltaic component 20 can be avoided during the connection process, and the photovoltaic component 20 has a better driving and connection effect.

[0078] Specifically, the transport unit 1 further includes a first lifting and adsorption assembly 6 and a second lifting and adsorption assembly 7, respectively located below the first gluing module 21 and the second gluing module 22. The first lifting and adsorption assembly 6 and the second lifting and adsorption assembly 7 are used to lift and adsorb the ends of the photovoltaic module 20, thereby providing support for the short sides of the photovoltaic module 20. Initially, the first lifting and adsorption assembly 6 and the second lifting and adsorption assembly 7 are both located below the current photovoltaic module 20, thereby avoiding interference during the transport of the photovoltaic module 20.

[0079] In this embodiment, after the first gluing module 21 and the second gluing module 22 are respectively located at the two ends of the long side, the first lifting and adsorption component 6 and the second lifting and adsorption component 7 are lifted synchronously to contact and adsorb the front and rear ends of the current photovoltaic component 20 respectively; while the first gluing module 21 and the second gluing module 22 are gluing the two short sides of the current photovoltaic component 20 along the short side direction, the first lifting and adsorption component 6 and the second lifting and adsorption component 7 both maintain a contact and adsorption state with the photovoltaic component 20; after the gluing of the two short sides is completed, the first lifting and adsorption component 6 and the second lifting and adsorption component 7 move away from the current photovoltaic component 20 and move to the initial state.

[0080] By means of the above method, the front and rear ends of the photovoltaic component 20 can be supported and adsorbed by the first lifting and adsorption component 6 and the second lifting and adsorption component 7, so that in the process of gluing the short sides of the two ends of the photovoltaic component 20, the photovoltaic component 20 can have a better stability effect, thereby making the gluing effect of the short sides of the photovoltaic component 20 better.

[0081] Specifically, the first gluing module 21 includes a fixed first gantry 211 and a first gluing head 212 that can move relative to the first gantry 211 in a direction perpendicular to the conveying direction of the photovoltaic module 20, so that the first gluing head 212 can complete the gluing effect on the short side during the movement relative to the first gantry 211. The second gluing module 22 includes a second gantry 221 that can move laterally along the conveying direction of the photovoltaic module 20 and a second gluing head 222 that can move relative to the second gantry 221 in a direction perpendicular to the conveying direction of the photovoltaic module 20. The movement effect of the second gantry 221 along the moving direction of the photovoltaic module 20 can adapt to photovoltaic modules 20 of different lengths. When the size, especially the length, of the photovoltaic module 20 changes, the distance between the first gantry 211 and the second gantry 221 can be changed by changing the position of the second gantry 221, thereby adapting to photovoltaic modules 20 of different specifications and sizes, thereby improving the compatibility of the gluing unit 2 with photovoltaic modules 20 of different sizes. The first gantry 211 and the second gantry 221 can remain stationary during the process of coating the edges of the photovoltaic module 20. During the coating of the two long sides, the first gluing head 212 and the second gluing head 222 also remain stationary. During the coating of the two short sides, the first gluing head 212 and the second gluing head 222 move relative to the first gantry 211 and the second gantry 221 respectively. Therefore, by moving the photovoltaic module 20 during the coating process, the transmission efficiency is higher, and the production efficiency is improved.

[0082] Specifically, the gluing device in this embodiment may further include the following steps during the gluing process:

[0083] While the current photovoltaic component 20 is performing step S4, the next photovoltaic component 20 is performing step S1 as the current photovoltaic component 20, so that the two photovoltaic components 20 can perform steps S4 and S1 respectively at the same time, so that the two adjacent photovoltaic components 20 can be located on the coating equipment at the same time, and in the process of coating the first long side of the current photovoltaic component 20, the next photovoltaic component 20 can be gradually and completely transported to the coating equipment.

[0084] While the current photovoltaic component 20 is performing step S5, the next photovoltaic component 20 performs step S2 as the current photovoltaic component 20, so that in the process of gluing the two short sides of the current photovoltaic component 20, the next photovoltaic component 20 can be corrected and positioned, so that the next photovoltaic component 20 can have the same position as the current photovoltaic component 20 relative to the linear transmission module 4.

[0085] While the current photovoltaic module 20 is performing step S6, the next photovoltaic module 20 is performing step S3 as the current photovoltaic module 20. This allows the next photovoltaic module 20 to move relative to the linear transmission module 4 under the drive of the mobile transmission module 5 during the process of gluing the other long side of the current photovoltaic module 20, so as to prepare for subsequent gluing. Afterwards, the next photovoltaic module 20 is performing steps S4, S5, and S6 in sequence as the current photovoltaic module 20, so that the next photovoltaic module 20 can complete the gluing. It is worth noting that while the next photovoltaic module 20 is performing steps S4, S5, and S6 in sequence as the current photovoltaic module 20, the next photovoltaic module 20 is also performing steps S1, S2, and S3 in sequence, thereby achieving simultaneous operation of any two adjacent photovoltaic modules 20.

[0086] By means of the above method, in the process of gluing multiple photovoltaic modules 20, different gluing steps can be performed simultaneously on adjacent photovoltaic modules 20, thereby achieving the effect of gluing the edges of adjacent photovoltaic modules 20 at the same time, thereby improving the gluing efficiency of the photovoltaic modules 20.

The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. At the same time, for those skilled in the art, according to the ideas of the present invention, there may be changes in the specific implementation methods and application scopes. In summary, the contents of this specification should not be understood as limiting the present invention.
