Description

Technical Field

[0001] This utility model relates to the field of photovoltaic equipment, specifically a device for applying adhesive to the edges of photovoltaic modules. Background Technology

[0002] Photovoltaic modules are important products in the photovoltaic power generation field, used to convert solar energy into electrical energy. A photovoltaic module consists of photovoltaic glass, solar cells mounted on the photovoltaic glass, and an encapsulating film covering the solar cells. During the manufacturing process, an adhesive applicator is used to apply adhesive around the perimeter of the photovoltaic module to seal the edges where the encapsulating film contacts the photovoltaic glass. In existing technologies, the photovoltaic glass is fixed to a suction cup pad using suction cups, and then a single applicator head is used to apply adhesive around the perimeter of the photovoltaic glass. The adhesive application is achieved by moving the applicator head relative to the perimeter of the photovoltaic module, while the photovoltaic module remains stationary. After the adhesive application process is complete, the photovoltaic module is transported to the next workstation. This results in problems such as long application time and low photovoltaic module transport efficiency. Utility Model Content

[0005] Furthermore, the mobile transmission module includes a first transmission component located at the front end of the first coating module and a second transmission component located at the rear end of the second coating module, respectively, in the photovoltaic module conveying direction.

[0006] Furthermore, the correction and positioning module includes a side-pushing correction component located on both sides of the first transmission component, a blocking component located above the end of the first transmission component near the first adhesive coating module, a rear correction component located at the end of the first transmission component away from the first adhesive coating module, and a vision component for detecting the photovoltaic module on the first transmission component.

[0007] Furthermore, the side-pushing correction assembly includes a first side-pushing correction module and two second side-pushing correction modules respectively disposed on both sides of the first transmission assembly. The first side-pushing correction module includes a first lateral movement module disposed perpendicular to the photovoltaic module's conveying direction and is connected to an elastic roller module. The second side-pushing correction module includes a second lateral movement module disposed perpendicular to the photovoltaic module's conveying direction and is connected to a rigid roller module.

[0008] Furthermore, both the first transmission component and the second transmission component include multiple conveyor belts spaced apart along a direction perpendicular to the photovoltaic module's conveying direction, and the mobile transmission module includes a first handling module and a second handling module capable of moving laterally and longitudinally between the first transmission component and the second transmission component.

[0009] Furthermore, the mobile transmission module also includes a first auxiliary transport module and a second auxiliary transport module capable of moving laterally and longitudinally between the first transport module and the second transport module. The upper surfaces of the first auxiliary transport module and the second auxiliary transport module are respectively arranged corresponding to the two long sides of the photovoltaic module. The first auxiliary transport module has a first adsorption transport module and a second adsorption transport module arranged sequentially along the front and back, and the second auxiliary transport module has a third adsorption transport module and a fourth adsorption transport module arranged sequentially along the front and back.

[0010] Furthermore, the upper surfaces of the first transport module, the second transport module, the first auxiliary transport module, and the second auxiliary transport module each have a plurality of suction cups arranged sequentially along their extension direction to adsorb the photovoltaic module after contacting it.

[0011] Furthermore, the first transport module, the second transport module, the third transport module, and the fourth transport module each have a fixedly installed transverse rack extending laterally along the photovoltaic module conveying direction, a helical gear meshing with the transverse rack, and a transport structure connected to the helical gear. The transport structure includes: a base plate connected to the helical gear; a linear drive unit located on the base plate and extending in the same direction as the transverse rack; a guide rail unit located on the base plate and extending in the same direction as the transverse rack, the guide rail unit corresponding to the linear drive unit; a guide rail slider slidably connected to the guide rail unit and connected to the linear drive unit; a connecting rod unit, both ends of which are rotatably connected to the guide rail slider and the vacuum suction plate, respectively; and a linear guide unit extending longitudinally, both ends of which are connected to the base plate and the vacuum suction plate, respectively.

[0012] Furthermore, the transmission unit also includes a first lifting adsorption component and a second lifting adsorption component located below the first adhesive coating module and the second adhesive coating module, respectively.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. A first and second gluing module are used together to apply glue to the photovoltaic module, and the photovoltaic module itself remains in motion during the gluing process. This allows the gluing process to be carried out by two gluing modules, thereby shortening the gluing time. Furthermore, the gluing process involves sequentially coating one long side, two short sides, and the other long side, which improves the utilization rate of the first and second gluing modules, reduces the idle time of the gluing modules, and thus improves the gluing efficiency. It also reduces the possibility of gluing instability caused by excessive downtime of either the first or second gluing module.

[0016] 2. This allows the photovoltaic module to be transported to both the inside and outside of the coating equipment, such that the photovoltaic module before adhesive coating is transported to the inside of the coating equipment, and the photovoltaic module after adhesive coating is transported to the outside of the coating equipment.

[0017] 3. The photovoltaic module is positioned from both sides by the side-pushing correction component, and the photovoltaic module is positioned from the conveying direction by the blocking component and the rear correction component. This achieves the correction and positioning effect of the photovoltaic module from both sides and front and back, so that different photovoltaic modules can have the same correction and positioning effect, and can avoid interference with the photovoltaic module during the correction and positioning process, so that the correction and positioning process has high stability.

[0018] 4. By using the first or second transport module to lift and adsorb adjacent photovoltaic modules, thereby driving the corresponding photovoltaic modules to move, multiple photovoltaic modules can be processed simultaneously, thereby improving the efficiency of processing photovoltaic modules.

[0019] 5. The first auxiliary handling module and the second auxiliary handling module can cooperate with the first handling module and the second handling module to drive the photovoltaic module to move, and in the process, they respectively support the long side and the other long side of the photovoltaic module, so that the photovoltaic module has good stability during movement and coating.

[0020] 6. By rotating the helical gear relative to the transverse rack and driving the guide rail slider with the linear drive unit, the photovoltaic module located on the vacuum suction cup can achieve lateral and longitudinal movement, thereby ensuring that the photovoltaic module has a relatively stable movement effect and improving the stability of the entire structure.

[0021] 7. The first and second lifting adsorption components can support and adsorb the front and rear ends of the photovoltaic module, thereby enabling the photovoltaic module to have a better stability effect during the process of applying adhesive to the short sides of the two ends of the photovoltaic module, thus making the adhesive application effect of the short sides of the photovoltaic module better.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1 to 9As shown in this embodiment, a photovoltaic module edge coating device is used to coat the edges of a photovoltaic module 20 with adhesive. It includes a transmission unit 1 for transporting the photovoltaic module 20 and a coating unit 2 for coating the photovoltaic module 20. The transmission unit 1 includes a correction and positioning module 3, a linear transmission module 4 extending laterally along the transport direction of the photovoltaic module 20, and a moving transmission module 5 capable of driving the photovoltaic module 20 to move laterally and longitudinally. The linear transmission module 4 allows the correction and positioning module 3 to correct different photovoltaic modules 20 to a standard position during the transport process. The linear transmission module 4 is used to transport the photovoltaic module 20 in a straight line along the transport direction. In this embodiment, the transport direction of the photovoltaic module 20 is... Figure 2 The width direction of the paper is specified. Of course, in other optional embodiments, the conveying direction of the photovoltaic module 20 can also be adjusted according to actual needs. The moving transmission module 5 enables the photovoltaic module 20 to move relative to the linear transmission module 4 in the horizontal and vertical directions. The glue coating unit 2 includes a first glue coating module 21 and a second glue coating module 22 arranged sequentially along the conveying direction of the photovoltaic module 20, wherein the first glue coating module 21 and the second glue coating module 22 can respectively coat the photovoltaic module 20 with glue.

[0036] In this embodiment, the adhesive application is completed through the following steps:

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

[0038] S2: The correction and positioning module 3 performs visual detection and correction positioning on the current photovoltaic module 20. The actual state of the current photovoltaic module 20 can be obtained through visual detection, and the position of the current photovoltaic module 20 can be corrected through correction positioning, so that different photovoltaic modules 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 module 20 to move so that one end of the front edge of the current photovoltaic module 20 is located under the first adhesive coating module 21. During this process, the mobile transmission module 5 drives the current photovoltaic module 20 to move relative to the linear transmission module 4 in the longitudinal and transverse directions so that the mobile transmission module 5 drives the current photovoltaic module 20 to change its position.

[0040] S4: The photovoltaic module 20 moves laterally relative to the first adhesive application module 21 along the moving transmission module 5 to apply adhesive to one long side of the photovoltaic module 20 and finally position the first adhesive application module 21 and the second adhesive application module 22 at the two ends of the long side, so that the adhesive application to one long side of the photovoltaic module 20 is completed by moving the first adhesive application module 21 relative to the photovoltaic module 20.

[0041] S5: Both the first glue-applying module 21 and the second glue-applying module 22 apply glue to the two short sides of the current photovoltaic module 20 along the short side direction. Thus, by moving the first glue-applying module 21 and the second glue-applying module 22 relative to the current photovoltaic module 20, the glue application on the two short sides of the photovoltaic module 20 is completed.

[0042] S6: The current photovoltaic module 20 moves laterally relative to the second adhesive coating module 22 along the moving transmission module 5 to apply adhesive to the other long side of the current photovoltaic module 20, so that the other end of the rear edge of the current photovoltaic module 20 is located under the second adhesive coating module 22, thereby completing the adhesive application of the current photovoltaic module 20. In this step, through the relative movement between the second adhesive coating module 22 and the current photovoltaic module 20, the other long side of the current photovoltaic module 20 is applied adhesive, and the other end of the rear edge of the current photovoltaic module 20 is located under the second adhesive coating module 22, which facilitates the application of adhesive to the next photovoltaic module 20.

[0043] With the above structure, the first glue-applying module 21 and the second glue-applying module 22 are used together to apply glue to the photovoltaic module 20, and the photovoltaic module 20 itself remains in motion during the glue-applying process. This allows the photovoltaic module 20 to be glued by two glue-applying modules, thereby shortening the glue application time. Furthermore, the glue is applied sequentially along one long side, two short sides, and the other long side, which improves the utilization rate of the first glue-applying module 21 and the second glue-applying module 22, reduces the idle time of the glue-applying modules, and thus improves the glue-applying efficiency. It also reduces the instability of glue application caused by the first glue-applying module 21 or the second glue-applying module 22 due to excessive downtime.

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

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

[0046] 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 near the first adhesive application module 21, a rear correction component 33 located at the end of the first transmission component 41 away from the first adhesive application module 21, and a vision component 34 for detecting the photovoltaic module 20 on the first transmission component 41.

[0047] 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 near the first adhesive application module 21, a rear correction component 33 located at the end of the first transmission component 41 away from the first adhesive application module 21, and a vision component 34 for detecting the photovoltaic module 20 on the first transmission component 41. The side-push correction component 31 is used to position the sides of the photovoltaic module 20, the blocking component 32 is used to position the front end of the photovoltaic module 20, and the rear correction component 33 is used to position the rear end of the photovoltaic module 20. After the photovoltaic module 20 passes over the rear correction component 33, the rear correction component 33 rises and moves forward so that both ends of the current photovoltaic module 20 abut against the blocking component 32 and the rear correction component 33 respectively, thereby limiting the photovoltaic module 20 in the conveying direction by the blocking component 32 and the rear correction component 33. It is worth noting that the positioning steps of the photovoltaic module 20 from both sides and in the conveying direction can be performed sequentially, or they can be performed simultaneously.

[0048] In the initial state, the distance between the side-pushing correction components 31 is greater than the width of the photovoltaic module 20, allowing the photovoltaic module 20 to pass through the area between the side-pushing correction components 31 and be conveyed forward. The rear correction component 33 is located below the first transmission component 41, allowing the photovoltaic module 20 to be conveyed above the rear correction component 33, avoiding interference from the rear correction component 33 on the photovoltaic module 20 during the conveying process. The vision component 34 is used for incoming material detection of the photovoltaic module 20, enabling the vision component 34 to detect the position and state of the photovoltaic module 20 located on the first transmission component 41.

[0049] With the above structure, the photovoltaic module 20 is positioned from both sides by the side-pushing correction component 31, and the photovoltaic module 20 is positioned from the conveying direction by the blocking component 32 and the rear correction component 33. This achieves the correction and positioning effect of the photovoltaic module 20 from both sides and front and back, so that different photovoltaic modules 20 can have the same correction and positioning effect, and interference with the photovoltaic module 20 can be avoided during the correction and positioning process, so that the correction and positioning process has high 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 disposed on both sides of the first transmission component 41. The first side-push correction module 311 includes a first transverse module 3111 disposed perpendicular to the conveying direction of the photovoltaic module 20. The first transverse module 3111 is connected to an elastic roller module 3112, so that the first transverse module 3111 can drive the elastic roller module 3112 to move closer to or further away from the photovoltaic module 20. The second side-pushing correction module 312 includes a second lateral movement module 3121 arranged perpendicular to the conveying direction of the photovoltaic module 20. The second lateral movement module 3121 is connected to a rigid roller module 3122, so that the second lateral movement module 3121 can drive the rigid roller module 3122 to move closer to or further away from the photovoltaic module 20. Preferably, the first side-pushing correction module 311 and the second side-pushing correction module 312 are staggered, that is, the area between the first side-pushing correction module 311 and the two second side-pushing correction modules 312 corresponds.

[0051] With the above structure, the first side-pushing correction module 311 and the second side-pushing correction module 312 jointly position the two sides of the photovoltaic module 20. During this process, the elastic roller module 3112 can buffer the photovoltaic module 20 upon contact, thereby protecting the photovoltaic module 20 during the positioning process. In addition, it can also disperse the force when positioning the two sides of the photovoltaic module 20, thereby avoiding the offset of the photovoltaic module 20 during the positioning of the two sides, and thus improving the stability of the photovoltaic module 20.

[0052] Specifically, both the first transmission component 41 and the second transmission component 42 include multiple conveyor belts 43 spaced apart along a direction perpendicular to the conveying direction of the photovoltaic module 20. These multiple conveyor belts 43 can simultaneously convey the photovoltaic modules 20 located on them. The mobile transmission module 5 includes a first transport module 51 and a second transport module 52 capable of moving laterally and longitudinally between the first transmission component 41 and the second transmission component 42. Initially, both the first transport module 51 and the second transport module 52 are located below the first transmission component 41, thereby preventing interference between the first transport module 51 and the second transport module 52 and the photovoltaic module 20 during the conveying process. The first transport module 51 and the second transport module 52 can respectively lift and adsorb adjacent photovoltaic modules 20, and drive the movement of two adjacent photovoltaic modules 20, thereby achieving the effect of the first transport module 51 and the second transport module 52 moving the current and the next photovoltaic module 20 respectively.

[0053] After the photovoltaic module 20 that is adsorbed is located in the second transmission component 42, the first transport module 51 or the second transport module 52 disconnects the adsorption and returns to the initial position, thereby facilitating the continuous transport of subsequent photovoltaic modules 20.

[0054] In this embodiment, the current photovoltaic module 20 and the next photovoltaic module 20 sequentially enter the first transport module 51. The current photovoltaic module 20 is lifted and adsorbed by the first transport module 51, which then moves the photovoltaic module 20. Subsequently, the next photovoltaic module 20 is lifted and adsorbed by the second transport module 52. After the first transport module 51 has positioned the current photovoltaic module 20 on the second transmission component 42, the first transport module 51 disconnects and returns to its initial position. The current photovoltaic module 20 is then transported backward by the second transmission component 42. Simultaneously, the next photovoltaic module 20 is used as the current photovoltaic module 20 for subsequent steps, and the first transmission component 41 lifts and adsorbs this next photovoltaic module 20, moving it. This allows the first transport module 51 and the second transport module 52 to effectively move two adjacent photovoltaic modules 20 respectively.

[0055] By using the above method, the first transport module 51 or the second transport module 52 is used to lift and adsorb adjacent photovoltaic modules 20, thereby driving the corresponding photovoltaic modules 20 to move, so that multiple photovoltaic modules 20 can be processed at the same time, thereby improving the efficiency of processing photovoltaic modules 20.

[0056] Specifically, the mobile transmission module 5 further includes a first auxiliary transport module 53 and a second auxiliary transport module 54 that can move laterally 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 module 20, so that the first auxiliary transport module 53 and the second auxiliary transport module 54 can support the long sides of the photovoltaic module 20 during the adhesive application process. The first auxiliary transport module 53 has a first adsorption and transport component 531 and a second adsorption and transport component 532 arranged sequentially along the front and back. The second auxiliary transport module 54 has a third adsorption and transport component 541 and a fourth adsorption and transport component 542 arranged sequentially along the front and back. In the initial state, the first adsorption and transport component 531 and the third adsorption and transport component 541 are both located below the first transport component 41, and the second adsorption and transport component 532 and the fourth adsorption and transport component 542 are both located below the adhesive coating unit 2. That is, in the transport direction of the photovoltaic module 20, the second adsorption and transport component 532 is located in front of the first adsorption and transport component 531, and the fourth adsorption and transport component 542 is located in front of the third adsorption and transport component 541.

[0057] In an optional embodiment:

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

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

[0060] The fourth adsorption and transmission component 542 is de-vacuumed and disconnected from the photovoltaic module 20, and the fourth adsorption and transmission component 542 returns to its 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 module 20. During this process, the third adsorption and transmission component 541 adsorbs the other long side of the photovoltaic module 20.

[0063] The third adsorption and transmission component 541 disconnects the vacuum and detaches from the photovoltaic module 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 module 20. The second adsorption and transmission component 532 and the second transport module 52 drive the photovoltaic module 20 to move towards the second transmission component 42.

[0064] The third adsorption and transmission component 541 is de-vacuumed and disconnected from the photovoltaic module 20, and the third adsorption and transmission component 541 returns to its initial state.

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

[0066] Using the above method, the first auxiliary handling module 53 and the second auxiliary handling module 54 can cooperate with the first handling module 51 and the second handling module 52 to drive the photovoltaic module 20 to move. In this process, they respectively support the long side and the other long side of the photovoltaic module 20, thereby making the photovoltaic module 20 have good stability during movement and adhesive application.

[0067] Specifically, the upper surfaces of the first transport module 51, the second transport module 52, the first auxiliary transport module 53, and the second auxiliary transport module 54 each have a plurality of suction cups 55 arranged sequentially along their extension direction, so as to adsorb the photovoltaic module 20 after contacting it.

[0068] Specifically, the first transport module 51, the second transport module 52, the third transport module, and the fourth transport module each have a fixedly installed transverse rack 8 extending laterally along the transport direction of the photovoltaic module 20, a helical gear 9 meshing with the transverse rack 8, and a transport structure 10 connected to the helical gear 9. The transverse rack 8 serves to guide the helical gear 9 and the transport structure 10. The helical gear 9 drives the transport structure 10 to move relative to the transverse rack 8, and the transport structure 10 drives the photovoltaic module 20 on it to move. The transport structure 10 includes:

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

[0070] A 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 lead 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 103 is located on the base plate 101 and extends in the same direction as the transverse rack 8. The guide rail 103 is correspondingly arranged with the linear drive unit 102.

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

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

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

[0075] In this embodiment, when the photovoltaic module 20 is positioned behind the vacuum suction plate, the helical gear 9 rotates, thereby moving relative to the transverse rack 8. This causes the conveying structure 10 to move laterally along the direction of movement of the photovoltaic module 20, enabling the photovoltaic module 20 to move laterally. The linear drive unit 102 drives the guide rail slider 104 and the guide rail part 103 to move relative to each other, thereby causing the connecting rod part 105 to change its angle with the transverse direction. This changes the longitudinal distance between the guide rail slider 104 and the vacuum suction plate. During this process, the linear guide part 106 provides longitudinal guidance, preventing any movement between the base plate 101 and the vacuum suction plate other than longitudinal movement, thus enabling the photovoltaic module 20 to move longitudinally.

[0076] With the above structure, the photovoltaic module 20 located on the vacuum suction cup 55 can move laterally and longitudinally by the rotation of the helical gear 9 relative to the transverse rack 8 and the linear drive unit 102 driving the guide rail slider 104, thereby ensuring that the photovoltaic module 20 has a relatively stable movement effect and improving the stability of the entire structure.

[0077] Specifically, the upper surfaces of the first transport module 51, the second transport module 52, the first auxiliary transport module 53, and the second auxiliary transport module 54 each have a plurality of suction cups 55 arranged sequentially along their extension direction, so as to adsorb the photovoltaic module 20 after contacting it. This results in a better connection between the first transport module 51, the second transport module 52, the first auxiliary transport module 53, and the second auxiliary transport module 54 and the photovoltaic module 20, and avoids damage to the photovoltaic module 20 during the connection process, thus providing a better driving and connection effect for the photovoltaic module 20.

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

[0079] In this embodiment, after the first adhesive coating module 21 and the second adhesive coating module 22 are respectively located at both ends of the long side, the first lifting adsorption component 6 and the second lifting adsorption component 7 are simultaneously lifted to contact and adsorb the front and rear ends of the current photovoltaic module 20, respectively. During the process of the first adhesive coating module 21 and the second adhesive coating module 22 applying adhesive to the two short sides of the current photovoltaic module 20 along the short side direction, the first lifting adsorption component 6 and the second lifting adsorption component 7 maintain contact and adsorption with the photovoltaic module 20. After the adhesive is applied to the two short sides, the first lifting adsorption component 6 and the second lifting adsorption component 7 move away from the current photovoltaic module 20 and return to the initial state.

[0080] Using the above method, the first lifting adsorption component 6 and the second lifting adsorption component 7 can support and adsorb the front and rear ends of the photovoltaic module 20, thereby enabling the photovoltaic module 20 to have a better stability effect during the process of applying adhesive to the short sides of the two ends of the photovoltaic module 20, and thus making the adhesive application effect of the short sides of the photovoltaic module 20 better.

[0081] Specifically, the first adhesive coating module 21 includes a fixedly mounted first gantry 211 and a first adhesive coating head 212 that can move relative to the first gantry 211 along a direction perpendicular to the conveying direction of the photovoltaic module 20. This allows the first adhesive coating head 212 to complete the adhesive coating effect on the short side while moving relative to the first gantry 211. The second adhesive coating module 22 includes a second gantry 221 that can move laterally along the conveying direction of the photovoltaic module 20 and a second adhesive coating head 222 that can move relative to the second gantry 221 along a direction perpendicular to the conveying direction of the photovoltaic module 20. The movement of the second gantry 221 along the moving direction of the photovoltaic module 20 can adapt to photovoltaic modules 20 of different lengths. Therefore, when the size of the photovoltaic module 20, especially its length, 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, and improving the compatibility of the adhesive coating unit 2 with photovoltaic modules 20 of different sizes. Both the first gantry 211 and the second gantry 221 can remain stationary during the process of applying adhesive to the four edges of the photovoltaic module 20. During the application of adhesive to the two long sides, the first adhesive application head 212 and the second adhesive application head 222 also remain stationary. However, during the application of adhesive to the two short sides, the first adhesive application head 212 and the second adhesive application head 222 move relative to the first gantry 211 and the second gantry 221, respectively. Thus, by moving the photovoltaic module 20 during the adhesive application process, high transmission efficiency is achieved, and production efficiency is improved.

[0082] Specifically, the adhesive coating equipment in this embodiment may further include the following steps during the adhesive coating process:

[0083] While the current photovoltaic module 20 is performing step S4, the next photovoltaic module 20 is performed as the current photovoltaic module 20 in step S1, so that the two photovoltaic modules 20 can simultaneously perform steps S4 and S1 respectively, so that the two adjacent photovoltaic modules 20 can be located on the coating device at the same time, and while the first long side of the current photovoltaic module 20 is being coated, the next photovoltaic module 20 can be gradually and completely transported to the coating device.

[0084] While the current photovoltaic module 20 is performing step S5, the next photovoltaic module 20 is used as the current photovoltaic module 20 to perform step S2. This allows the next photovoltaic module 20 to be corrected and positioned during the process of applying adhesive to the two short sides of the current photovoltaic module 20, so that the next photovoltaic module 20 can have the same position as the current photovoltaic module 20 relative to the linear transmission module 4.

[0085] While the current photovoltaic module 20 is performing step S6, the next photovoltaic module 20, acting as the current photovoltaic module 20, is performing step S3. This allows the next photovoltaic module 20 to move relative to the linear transmission module 4 under the guidance of the moving transmission module 5 during the application of adhesive to the other long side of the current photovoltaic module 20, preparing for subsequent adhesive application. Then, the next photovoltaic module 20, acting as the current photovoltaic module 20, sequentially performs steps S4, S5, and S6, allowing it to complete the adhesive application. It is worth noting that while the next photovoltaic module 20 is acting as the current photovoltaic module 20, performing steps S4, S5, and S6, the photovoltaic module 20 following it sequentially performs steps S1, S2, and S3, thus enabling simultaneous operation of any two adjacent photovoltaic modules 20.

[0086] By means of the above method, during the process of applying adhesive to multiple photovoltaic modules 20, different adhesive application steps can be performed on adjacent photovoltaic modules 20 at the same time, thereby achieving the effect of applying adhesive to the four edges of adjacent photovoltaic modules 20 at the same time, thus improving the adhesive application efficiency of photovoltaic modules 20.
