Description

Technical Field

[0001] The present invention relates to the field of photovoltaics, and specifically to a method for applying glue to the four peripheral edges of a photovoltaic module. Background Art

[0002] Photovoltaic modules are important products in the field of photovoltaic power generation, and are used to convert solar energy into electrical energy. A photovoltaic module is composed of structures such as photovoltaic glass, solar cells disposed on the photovoltaic glass, and a glue film covering the solar cells. During the production process of the photovoltaic module, a glue application device is required to apply glue to the four sides of the photovoltaic module to coat a sealant on the four peripheral edges where the glue film contacts the photovoltaic glass. In the prior art for applying glue to photovoltaic modules, the photovoltaic glass is fixed on a suction pad plate through a suction cup, and then a single nozzle is used to apply glue around the four peripheral edges of the photovoltaic glass plate. During the entire glue application process, the glue application effect is achieved by the relative movement of the glue application head with respect to the four sides of the photovoltaic module, and the photovoltaic module remains stationary during this process. After the entire glue application process is completed, the photovoltaic module is then transported to the subsequent workstations, resulting in problems such as a relatively long coating time and a low transportation efficiency of the photovoltaic module.

[0010] Furthermore, the mobile transmission module further includes a first auxiliary handling module and a second auxiliary handling module that can move horizontally and vertically between the first transmission component and the second transmission component.

[0011] Further, the upper surfaces of the first handling module, the second handling module, the first auxiliary handling module, and the second auxiliary handling module are each provided with a plurality of suction cups arranged in sequence along their extending directions, so as to adsorb the photovoltaic module after contacting the photovoltaic module.

[0014] The beneficial effects of the present invention are as follows:

[0015] 1. The first glue application module and the second glue application module are used together to apply glue to the photovoltaic module, and the photovoltaic module itself remains in a moving state during the glue application process, so that during the glue application process, the two glue application modules are used to apply glue to the photovoltaic module, thereby shortening the glue application time, and during the glue application process, a long side, two short sides, and another long side are coated in sequence, thereby improving the utilization rate of the first glue application module and the second glue application module, reducing the idle time of the glue application module, thereby improving the glue application efficiency, and reducing the situation of unstable glue application caused by the first glue application module or the second glue application module stopping for too long.

[0016] 2. During the process of applying glue to multiple photovoltaic modules, different glue application steps can be simultaneously performed on adjacent photovoltaic modules, so as to achieve the effect of simultaneously applying glue to the four peripheral edges of adjacent photovoltaic modules, thereby improving the glue application efficiency of the photovoltaic modules.

[0017] 3. Position the photovoltaic module from both sides through the side pushing and correcting assembly, and cooperate with the blocking assembly and the rear correcting assembly to position the photovoltaic module in the conveying direction, so as to achieve the effect of correcting and positioning the photovoltaic module from both sides and front and back, so that different photovoltaic modules can have the same correcting and positioning effect, and interference with the photovoltaic module during the correcting and positioning process can be avoided, making the correcting and positioning process have high stability.

[0018] 4. The first side pushing and correcting module and the second side pushing and correcting module jointly position both sides of the photovoltaic module. During this process, the elastic roller module can buffer with the photovoltaic module when contacting, and thus play a role in protecting the photovoltaic module during the positioning process. In addition, it also enables the acting force to be dispersed when positioning both sides of the photovoltaic module, thereby avoiding the offset of the photovoltaic module during the positioning of both sides, and further improving the stability of the photovoltaic module.

[0019] 5. The front and rear ends of the photovoltaic module can be supported and adsorbed by the first lifting and adsorbing assembly and the second lifting and adsorbing assembly, so that during the process of applying glue to the short sides at both ends of the photovoltaic module, the photovoltaic module can have a better stable effect, and thus the glue application effect on the short sides of the photovoltaic module is better.

[0020] 6. During the coating process of the two long sides, the first glue applicator head and the second glue applicator head also remain stationary, while during the glue application process of the two short sides, the first glue applicator head and the second glue applicator head move relative to the first gantry and the second gantry respectively. Thus, by making the photovoltaic module move during the glue application process, it has a high transmission efficiency and improves the production efficiency.

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] As Figures 1 to 9 shown, a method for applying glue to the four peripheral edges of a photovoltaic module in this embodiment applies glue to the four peripheral edges of the photovoltaic module 20 through a coating device. The coating device includes a transmission unit 1 for transmitting the photovoltaic module 20 and a glue application unit 2 for applying glue to the photovoltaic module 20. The transmission unit 1 includes a correction and positioning module 3, a linear transmission module 4 extending horizontally along the conveying direction of the photovoltaic module 20, and a moving transmission module 5 capable of driving the photovoltaic module 20 to move in the horizontal and vertical directions. 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 along a straight line in the conveying direction. In this embodiment, the conveying direction of the photovoltaic module 20 is Figure 2 the width direction of the paper surface in []. 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 application unit 2 includes a first glue application module 21 and a second glue application module 22 arranged in sequence along the conveying direction of the photovoltaic module 20. Among them, the first glue application module 21 and the second glue application module 22 can apply glue to the photovoltaic module 20 respectively.

[0035] The glue application method includes the following steps:

[0036] S1: The current photovoltaic module 20 moves with the linear transmission module 4 and is completely placed on the linear transmission module 4, so that the current photovoltaic module 20 can gradually enter the linear transmission module 4 from the outside of the linear transmission module 4 through the conveying of the linear transmission module 4, so that the current photovoltaic module 20 can be gradually and completely conveyed onto the coating device.

[0037] S2: The correction and positioning module 3 performs visual inspection and correction and positioning on the current photovoltaic module 20. Through visual inspection, the actual state of the current photovoltaic module 20 can be obtained. Through correction and positioning, the position of the current photovoltaic module 20 can be corrected, so that different photovoltaic modules 20 can have the same position relative to the linear transmission module 4 after correction.

[0038] 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 glue - applying 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 longitudinally and transversely, so as to enable the mobile transmission module 5 to drive the current photovoltaic module 20 to change its position.

[0039] S4: The current photovoltaic module 20 moves transversely relative to the first glue - applying module 21 along with the mobile transmission module 5, so as to apply glue to one long side of the current photovoltaic module 20 and finally make the first glue - applying module 21 and the second glue - applying module 22 be located at both ends of this long side respectively. Thus, by making the first glue - applying module 21 move relative to the current photovoltaic module 20, the glue - applying to one long side of the photovoltaic module 20 is completed.

[0040] 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 the relative movement of the first glue - applying module 21 and the second glue - applying module 22 relative to the current photovoltaic module 20, the glue - applying to the two short sides of the photovoltaic module 20 is completed.

[0041] S6: The current photovoltaic module 20 moves transversely relative to the second glue - applying module 22 along with the mobile transmission module 5, so as to apply glue to the other long side of the current photovoltaic module 20 and finally make the other end of the rear edge of the current photovoltaic module 20 be located under the second glue - applying module 22, so as to complete the glue - applying to the current photovoltaic module 20. In this step, through the relative movement between the second glue - applying module 22 and the current photovoltaic module 20, and during this process, the glue - applying to the other long side of the current photovoltaic module 20 is completed, and finally making the other end of the rear edge of the current photovoltaic module 20 be located under the second glue - applying module 22 can facilitate the glue - applying to the next photovoltaic module 20.

[0042] By the above method, the first gluing module 21 and the second gluing module 22 are used together to glue the photovoltaic module 20, and the photovoltaic module 20 itself remains in a moving state during the gluing process, so that during the gluing process, the two gluing modules are used to glue the photovoltaic module 20, thereby shortening the gluing time. And during the gluing process, one long side, two short sides and the other 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, and then improving the gluing efficiency. And it can reduce the situation of unstable gluing caused by the first gluing module 21 or the second gluing module 22 due to too long stop time.

[0043] Specifically, the following steps are further included:

[0044] While the current photovoltaic module 20 is performing step S4, the next photovoltaic module 20 serves as the current photovoltaic module 20 to perform step S1, so that the two photovoltaic modules 20 can perform step S4 and step S1 respectively at the same time, so that two adjacent photovoltaic modules 20 can be located on the coating equipment at the same time. And during the process of coating the first long side of the current photovoltaic module 20, the next photovoltaic module 20 can be gradually and completely conveyed onto the coating equipment.

[0045] While the current photovoltaic module 20 is performing step S5, the next photovoltaic module 20 serves as the current photovoltaic module 20 to perform step S2, so that during the process of gluing the two short sides of the current photovoltaic module 20, the next photovoltaic module 20 can be corrected and positioned, so that the next photovoltaic module 20 can have the same position relative to the linear transmission module 4 as the current photovoltaic module 20.

[0046] While the current photovoltaic module 20 is performing step S6, the next photovoltaic module 20 serves as the current photovoltaic module 20 to perform step S3, so that during the process of gluing the other long side of the current photovoltaic module 20, the next photovoltaic module 20 can move relative to the linear transmission module under the drive of the moving transmission module 5 to prepare for subsequent gluing. After that, the next photovoltaic module 20 serves as the current photovoltaic module 20 to perform steps S4, S5 and S6 in sequence, so that the next photovoltaic module 20 can complete gluing. It should be noted that when the next photovoltaic module 20 serves as the current photovoltaic module 20 to perform steps S4, S5 and S6 in sequence, the next photovoltaic module 20 of this piece performs steps S1, S2 and S3 in sequence, so as to realize the simultaneous operation of any two adjacent photovoltaic modules 20.

[0047] By the above method, during the process of gluing multiple pieces of the photovoltaic module 20, different gluing steps can be simultaneously performed on adjacent photovoltaic modules 20, so that the effect of simultaneously gluing the four peripheries of adjacent photovoltaic modules 20 can be achieved, thereby improving the gluing efficiency of the photovoltaic module 20.

[0048] Specifically, the mobile transmission module 5 includes a first transmission component 41 located at the front end of the first gluing module 21 and a second transmission component 42 located at the rear end of the second gluing module 22 in the conveying direction of the photovoltaic module 20. Among them, the first transmission component 41 is used to convey the photovoltaic module 20 into the coating equipment, and the second transmission component 42 is used to convey the photovoltaic module 20 after gluing backward and gradually convey it outside the coating equipment.

[0049] In step S1, the first transmission component 41 drives the current photovoltaic module 20 to be conveyed forward in the transverse direction, so that the first transmission component 41 can drive the photovoltaic module 20 to be conveyed forward, and then the photovoltaic module 20 enters the coating equipment.

[0050] After step S6, the second transmission component 42 drives the current photovoltaic module 20 after gluing to be conveyed forward in the transverse direction, so that the second transmission component 42 can drive the photovoltaic module 20 to be conveyed forward, and then the photovoltaic module 20 is gradually conveyed outside the coating equipment.

[0051] By the above steps, the photovoltaic module 20 can be conveyed inside and outside the coating equipment, so that the photovoltaic module 20 before gluing is conveyed into the coating equipment, and the photovoltaic module 20 after gluing is conveyed outside the coating equipment.

[0052] Specifically, the correction and positioning module 3 includes side push correction components 31 located on both sides of the first transmission component 41, a blocking component 32 located above one end of the first transmission component 41 adjacent to the first glue application module 21, a rear correction component 33 located at one end of the first transmission component 41 away from the first glue application module 21, and a vision component 34 for detecting the photovoltaic module 20 on the first transmission component 41. Among them, the side push correction components 31 are used to position both 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. In the initial state, the distance between the side push correction components 31 is greater than the width of the photovoltaic module 20, so that the photovoltaic module 20 can pass through the area between the side push correction components 31 and be conveyed forward. The rear correction component 33 is located below the first transmission component 41, so that the photovoltaic module 20 can be conveyed above the rear correction component 33, avoiding interference of the rear correction component 33 with the photovoltaic module 20 during the conveying process. In step S2, the following steps are included:

[0053] The current photovoltaic module 20 moves forward with the first transmission component 41, and the vision component 34 performs incoming material detection on the photovoltaic module 20, so that the vision component 34 can perform incoming material detection on the photovoltaic module 20 located on the first transmission component 41, and then detect the position and state of the photovoltaic module 20.

[0054] After the current photovoltaic module 20 passes over the rear correction component 33, the rear correction component 33 jacks up and moves forward so that both ends of the current photovoltaic module 20 are respectively abutted against the blocking component 32 and the rear correction component 33, so that the photovoltaic module 20 is limited in the conveying direction of the photovoltaic module 20 by the blocking component 32 and the rear correction component 33.

[0055] The side push correction components 31 gradually approach the photovoltaic module 20 along both sides and finally abut against both sides of the current photovoltaic module 20, so that the photovoltaic module 20 is positioned from both sides by the side push correction components 31. It should be noted that the positioning steps of the photovoltaic module 20 from both sides and in the conveying direction can have a front-back sequence. Of course, they can also be completed simultaneously.

[0056] The side push correction components 31 and the rear correction component 33 move away from the current photovoltaic module 20 and return to the initial position, so that the corrected photovoltaic module 20 can be conveyed backward, while the side push correction components 31 and the rear correction component 33 can re-correct and position the next photovoltaic module 20.

[0057] By the above method, the photovoltaic module 20 is positioned from both sides by the side-pushing correction assembly 31, and is positioned from the conveying direction in cooperation with the blocking assembly 32 and the rear correction assembly 33, so as to achieve the correction and positioning effect on 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 the interference to the photovoltaic module 20 during the correction and positioning process can be avoided, making the correction and positioning process have high stability.

[0058] Specifically, the side-pushing correction assembly 31 includes one first side-pushing correction module 311 and two second side-pushing correction modules 312 respectively arranged on both sides of the first transmission assembly 41. Among them, the first side-pushing correction module 311 includes a first transverse movement module 3111 arranged perpendicular to the conveying direction of the photovoltaic module 20, and the first transverse movement module 3111 is connected with an elastic roller module 3112, so that the first transverse movement module 3111 can drive the elastic roller module 3112 to approach or move away from the photovoltaic module 20. The second side-pushing correction module 312 includes a second transverse movement module 3121 arranged perpendicular to the conveying direction of the photovoltaic module 20, and the second transverse movement module 3121 is connected with a rigid roller module 3122, so that the second transverse movement module 3121 can drive the rigid roller module 3122 to approach or move away from the photovoltaic module 20. Preferably, the first side-pushing correction module 311 and the second side-pushing correction module 312 are arranged in an interleaved manner, that is, the areas between the first side-pushing correction module 311 and the two second side-pushing correction modules 312 correspond. In the step "after the current photovoltaic module 20 passes over the rear correction assembly 33, the rear correction assembly 33 jacks up and moves forward so that both ends of the current photovoltaic module 20 are respectively abutted against the blocking assembly 32 and the rear correction assembly 33", specifically:

[0059] The first side-pushing correction module 311 and the second side-pushing correction module 312 move towards each other simultaneously, so that the first side-pushing correction module 311 and the second side-pushing correction module 312 are respectively abutted against both sides of the photovoltaic module 20. Preferably, the two second side-pushing correction modules 312 position the photovoltaic module 20 from one side, and the first side-pushing correction module 311 positions the photovoltaic module 20 from the middle area between the two second side-pushing correction modules 312 from the other side.

[0060] By the above method, the first side-pushing and correcting module 311 and the second side-pushing and correcting module 312 jointly position both sides of the photovoltaic module 20. During this process, the elastic roller module 3112 can buffer with the photovoltaic module 20 when in contact, thereby protecting the photovoltaic module 20 during the positioning process. In addition, it also enables the dispersion of the acting force when positioning both sides of the photovoltaic module 20, thereby avoiding the deviation of the photovoltaic module 20 during the positioning of both sides, and further improving the stability of the photovoltaic module 20.

[0061] Specifically, both the first transmission component 41 and the second transmission component 42 include a plurality of conveyor belts 43 arranged at intervals along a direction perpendicular to the conveying direction of the photovoltaic module 20. The plurality of conveyor belts 43 can simultaneously convey the photovoltaic module 20 located thereon. The mobile transmission module 5 includes a first handling module 51 and a second handling module 52 that can move horizontally and vertically between the first transmission component 41 and the second transmission component 42. In the initial state, both the first handling module 51 and the second handling module 52 are located below the first transmission component 41, so as to avoid the interference of the first handling module 51 and the second handling module 52 with the photovoltaic module 20 during the conveying process of the photovoltaic module 20. In steps S1 - S6, the following steps are included:

[0062] The first handling module 51 and the second handling module 52 respectively lift and adsorb the adjacent photovoltaic modules 20 and drive the adjacent two photovoltaic modules 20 to move, so as to achieve the effect that the first handling module 51 and the second handling module 52 respectively move the current and the next photovoltaic module 20.

[0063] After driving the correspondingly adsorbed photovoltaic module 20 to be located on the second transmission component 42, the first handling module 51 or the second handling module 52 disconnects the adsorption and returns to the initial position, so as to facilitate the continuous conveying of the subsequent photovoltaic modules 20.

[0064] In this embodiment, the current photovoltaic module 20 and the next photovoltaic module 20 sequentially enter the first handling module 51. The current photovoltaic module 20 is lifted and adsorbed by the first handling module 51, and the first handling module 51 drives the photovoltaic module 20 to move. Subsequently, the next photovoltaic module 20 is lifted and adsorbed by the second handling module 52. After the first handling module 51 drives the current photovoltaic module 20 to be located on the second transmission component 42, the first handling module 51 disconnects the adsorption and returns to the initial position. The current photovoltaic module 20 is conveyed backward by the second transmission component 42. At the same time, the next photovoltaic module 20 serves as the current photovoltaic module 20 for subsequent steps, and the first transmission component 41 then lifts and adsorbs the photovoltaic module 20 that serves as the next one at this time, and drives the photovoltaic module 20 to move, so that the first handling module 51 and the second handling module 52 complete the effect of driving two adjacent photovoltaic modules 20 to move respectively.

[0065] By means of the above method, by using the first handling module 51 or the second handling module 52 to lift and adsorb adjacent photovoltaic modules 20 respectively, and then driving the corresponding photovoltaic modules 20 to move, multiple photovoltaic modules 20 can be processed simultaneously, thereby improving the efficiency of processing the photovoltaic modules 20.

[0066] Specifically, the mobile transmission module 5 further includes a first auxiliary handling module 53 and a second auxiliary handling module 54 that can move horizontally and vertically between the first transmission component 41 and the second transmission component 42. The upper surfaces of the first auxiliary handling module 53 and the second auxiliary handling module 54 are respectively arranged corresponding to the two long sides of the photovoltaic module 20, so that the first auxiliary handling module 53 and the second auxiliary handling module 54 can support the long sides of the photovoltaic module 20 during the gluing process. Among them, the first auxiliary handling module 53 has a first adsorption and transmission component 531 and a second adsorption and transmission component 532 arranged in sequence from front to back, and the second auxiliary handling module 54 has a third adsorption and transmission component 541 and a fourth adsorption and transmission component 542 arranged in sequence from front to back. In the initial state, both the first adsorption and transmission component 531 and the third adsorption and transmission component 541 are located below the first transmission component 41, and both the second adsorption and transmission component 532 and the fourth adsorption and transmission component 542 are located below the gluing unit 2. That is, in the conveying direction of the photovoltaic module 20, the second adsorption and transmission component 532 is in front of the first adsorption and transmission component 531, and the fourth adsorption and transmission component 542 is in front of the third adsorption and transmission component 541. In steps S1 - S6, the following steps are included:

[0067] The first adsorption and transfer component 531 synchronously adsorbs and lifts with the first handling module 51 and drives the photovoltaic module 20 to move. During this process, the first adsorption and transfer component 531 adsorbs one long side of the photovoltaic module 20;

[0068] The first adsorption and transfer component 531 cuts off the vacuum and disengages from the photovoltaic module 20. The first adsorption and transfer component 531 returns to its initial state. The fourth adsorption and transfer component 542 jacks up and adsorbs the photovoltaic module 20. The fourth adsorption and transfer component 542 and the first handling module 51 drive the photovoltaic module 20 to move towards the second transfer component 42;

[0069] The fourth adsorption and transfer component 542 cuts off the vacuum and disengages from the photovoltaic module 20. The fourth adsorption and transfer component 542 returns to its initial state;

[0070] Or,

[0071] The third adsorption and transfer component 541 synchronously adsorbs and lifts the photovoltaic module 20 with the second handling module 52. During this process, the third adsorption and transfer component 541 adsorbs the other long side of the photovoltaic module 20;

[0072] The third adsorption and transfer component 541 cuts off the vacuum and disengages from the photovoltaic module 20. The third adsorption and transfer component 541 returns to its initial state. The second adsorption and transfer component 532 jacks up and adsorbs the photovoltaic module 20. The second adsorption and transfer component 532 and the second handling module 52 drive the photovoltaic module 20 to move towards the second transfer component 42;

[0073] The third adsorption and transfer component 541 cuts off the vacuum and disengages from the photovoltaic module 20. The third adsorption and transfer component 541 returns to its initial state.

[0074] It should be noted that since the first handling module 51 and the second handling module 52 drive the adjacent two photovoltaic modules 20 to move respectively, the above two steps are carried out in sequence one after another.

[0075] By means of 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, thereby driving the photovoltaic module 20 to move, and respectively playing a supporting role on the long side and the other long side of the photovoltaic module 20 during this process, so that the photovoltaic module 20 has good stability during both movement and gluing.

[0076] Specifically, the upper surfaces of the first handling module 51, the second handling module 52, the first auxiliary handling module 53, and the second auxiliary handling module 54 are each provided with a plurality of suction cups 55 arranged in sequence along their extending directions. After contacting the photovoltaic module 20, the suction cups 55 adsorb the photovoltaic module 20, so that there is a good connection effect between the first handling module 51, the second handling module 52, the first auxiliary handling module 53, the second auxiliary handling module 54 and the photovoltaic module 20. During the connection process, damage to the photovoltaic module 20 can be avoided, and there is a good driving and connection effect on the photovoltaic module 20.

[0077] Specifically, the transmission unit 1 further includes a first lifting and adsorbing assembly 6 and a second lifting and adsorbing assembly 7 respectively located below the first glue application module 21 and the second glue application module 22. The first lifting and adsorbing assembly 6 and the second lifting and adsorbing assembly 7 are used to jack up and adsorb the ends of the photovoltaic module 20, so as to support the short sides of the photovoltaic module 20. In the initial state, the first lifting and adsorbing assembly 6 and the second lifting and adsorbing assembly 7 are both located below the current photovoltaic module 20, so as to avoid interference during the conveying process of the photovoltaic module 20. In step S5, the following steps are included:

[0078] After the first glue application module 21 and the second glue application module 22 are respectively located at both ends of the long side, the first lifting and adsorbing assembly 6 and the second lifting and adsorbing assembly 7 are lifted synchronously to respectively contact and adsorb the front and rear ends of the current photovoltaic module 20;

[0079] During the process that the first glue application module 21 and the second glue application module 22 both apply glue to the two short sides of the current photovoltaic module 20 along the short side direction, the first lifting and adsorbing assembly 6 and the second lifting and adsorbing assembly 7 both maintain the contact and adsorption state with the photovoltaic module 20;

[0080] After the two short sides are finished applying glue, the first lifting and adsorbing assembly 6 and the second lifting and adsorbing assembly 7 move away from the current photovoltaic module 20 and return to the initial state.

[0081] By means of the above method, the front and rear ends of the photovoltaic module 20 can be supported and adsorbed by the first lifting and adsorbing assembly 6 and the second lifting and adsorbing assembly 7. Furthermore, during the process of applying glue to the two short sides of the photovoltaic module 20, the photovoltaic module 20 can have a good stability effect, and thus the glue application effect on the short sides of the photovoltaic module 20 is better.

[0082] Specifically, the first glue application module 21 includes a fixedly arranged first gantry 211 and a first glue applicator 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 glue applicator head 212 can complete the glue application effect on the short sides during the process of moving relative to the first gantry 211. The second glue application module 22 includes a second gantry 221 that can move horizontally in the conveying direction of the photovoltaic module 20 and a second glue applicator 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 in the moving direction of the photovoltaic module 20 can adapt to different lengths of the photovoltaic module 20. Furthermore, when the size of the photovoltaic module 20, especially the length, changes, by changing the position of the second gantry 221, the distance between the first gantry 211 and the second gantry 221 can be changed, so as to adapt to different specifications and sizes of the photovoltaic module 20, thereby improving the compatibility of the glue application unit 2 with different sizes of the photovoltaic module 20. During the glue application process on the four peripheral edges of the photovoltaic module 20, both the first gantry 211 and the second gantry 221 can remain stationary. During the coating process on the two long sides, the first glue applicator head 212 and the second glue applicator head 222 also remain stationary. However, during the glue application process on the two short sides, the first glue applicator head 212 and the second glue applicator head 222 move relative to the first gantry 211 and the second gantry 221 respectively. Thus, by moving the photovoltaic module 20 during the glue application process, it has a high transmission efficiency and improves the production efficiency.
