Description

Technical Field

[0001] This utility model relates to the field of photovoltaic module coating technology, and more specifically, to a coating device and photovoltaic production equipment. Background Technology

[0002] With the rapid development of the photovoltaic industry, the production efficiency and product quality of photovoltaic modules have become crucial factors affecting their market competitiveness. In the photovoltaic module encapsulation process, the frame, as a vital structural component supporting and fixing the battery module, is typically bonded and sealed to the module using specialized silicone to improve structural stability and waterproofing. Currently, the adhesive coating process for photovoltaic frames mainly relies on automated adhesive coating equipment, where an adhesive applicator drives an applicator head to apply silicone to the frame slots. Traditional adhesive coating methods often use a single plastic flat applicator head for continuous coating. While this method achieves automation, it still has many shortcomings in practical applications.

[0003] Therefore, there is an urgent need to propose a new coating method to solve the technical problems of low coating efficiency and uneven coating in the existing technology, thereby improving the production efficiency and product quality of photovoltaic modules. Utility Model Content

[0004] This invention provides a coating device and photovoltaic production equipment, which can improve coating efficiency and make coating more uniform.

[0005] The embodiments of this utility model can be implemented as follows:

[0006] An embodiment of this utility model provides an adhesive application device, which includes:

[0007] First applicator head;

[0008] The second glue applicator is offset from the first glue applicator and is used to apply glue to the glue-applying surface of the frame, either separately or simultaneously.

[0009] Optionally, the first and second glue applicators are offset vertically.

[0010] Optionally, the first and second glue applicators are staggered in the horizontal direction.

[0011] Optionally, the adhesive application device further includes an adhesive applicator, which is connected to both the first adhesive applicator head and the second adhesive applicator head.

[0015] Optionally, the diameter of the first glue applicator and / or the second glue applicator is 1mm-5mm.

[0016] Optionally, the adhesive application device further includes a first adhesive dispensing control valve and a second adhesive dispensing control valve. The first adhesive dispensing control valve is disposed on the first adhesive application head, and the second adhesive dispensing control valve is disposed on the second adhesive application head.

[0018] The beneficial effects of the adhesive coating device and photovoltaic production equipment of this utility model include, for example:

[0019] This adhesive coating device includes a first coating head and a second coating head, which are staggered. The second and first coating heads are used to apply adhesive to the coating surface of the frame, either separately or simultaneously. In use, by setting up the first and second coating heads and spatially staggering them, adhesive application to the frame's coating surface can be performed separately or simultaneously. Through the coordinated operation of the first and second coating heads, more coating paths are completed per unit time, significantly improving coating efficiency and making it suitable for automated production of large-scale photovoltaic modules.

[0020] This photovoltaic production equipment includes a frame and an adhesive coating device, which is used to apply adhesive to the frame. In use, by setting up a first adhesive coating head and a second adhesive coating head, and arranging them in a staggered spatial configuration, adhesive can be applied to the adhesive-coating surface of the frame separately or simultaneously. The coordinated operation of the first and second adhesive coating heads completes more adhesive coating paths per unit time, significantly improving coating efficiency and making it suitable for automated production of large-scale photovoltaic modules. Furthermore, the first and second adhesive coating heads can be controlled separately in terms of adhesive dispensing volume and speed. Their staggered arrangement ensures a more uniform and consistent adhesive distribution, avoiding the uneven dispensing problem caused by pressure variations in traditional single-head adhesive coating.

[0032] It should be noted that, where there is no conflict, the features in the embodiments of this utility model can be combined with each other.

[0033] With the rapid development of the photovoltaic industry, the production efficiency and product quality of photovoltaic modules have become important factors affecting their market competitiveness. In the photovoltaic module encapsulation process, the frame, as a crucial structural component supporting and fixing the battery module, is typically sealed to the module by coating it with specialized silicone to improve the module's structural stability and waterproof performance.

[0034] Currently, the adhesive coating process for photovoltaic (PV) frames mainly relies on automated adhesive coating equipment. The adhesive coating machine drives an adhesive applicator to coat the frame grooves with silicone. Traditional adhesive coating methods often use a single plastic flat applicator for continuous coating. While this method achieves automation, it still has several shortcomings in practical applications: First, the traditional single applicator is subjected to significant pressure during the adhesive dispensing process, making it prone to deformation and resulting in uneven dispensing, affecting coating quality. Second, relying on only a single applicator to complete the entire coating process results in low coating efficiency, making it difficult to meet the cycle time requirements of large-scale production. Third, the flowability of the silicone is difficult to control during the coating process, easily leading to overflow or insufficient coating, affecting the sealing and bonding strength of the module. Furthermore, traditional adhesive coating methods have high silicone consumption per unit, increasing module manufacturing costs. Finally, existing adhesive coating methods suffer from limitations in coating position and insufficient bonding area when dealing with new A-side-less full-screen PV frames, making it difficult to meet the process requirements of new modules.

[0035] Therefore, there is an urgent need to propose a new coating method to solve the technical problems in the existing technology, such as low coating efficiency, uneven coating, poor control of glue overflow, high silicone consumption, and difficulty in adapting to new frame structures, so as to improve the production efficiency and product quality of photovoltaic modules.

[0036] Please refer to Figures 1-4This embodiment provides a photovoltaic production equipment 1000, including a frame 200 and an adhesive applicator 100. The adhesive applicator 100 is used to apply adhesive to the frame 200. This photovoltaic production equipment 1000 can effectively improve the technical problems mentioned above, improve adhesive application efficiency, and make the adhesive application more uniform.

[0037] Please refer to Figures 1-4 This embodiment provides an adhesive application device 100 including a first adhesive application head 10 and a second adhesive application head 20. The second adhesive application head 20 and the first adhesive application head 10 are staggered and are used to apply adhesive to the adhesive application surface of the frame 200, either separately or simultaneously.

[0038] In this embodiment, the adhesive applicator 100 is applicable to both conventional bezels and bezels of full-screen displays without an A-side. The first adhesive applicator 10 and the second adhesive applicator 20 are distributed at the bottom of the groove in the bezel 200 and near the C-side of the groove, facilitating control of adhesive overflow and improving process adaptability. Specifically, the distribution of the first adhesive applicator 10 and the second adhesive applicator 20 at the bottom of the groove in the bezel 200 and near the C-side helps control the direction and range of silicone flow, improving adhesive overflow control and meeting the sealing requirements of component encapsulation.

[0039] In this embodiment, the first glue applicator 10 and the second glue applicator 20 are staggered vertically. In other embodiments, the first glue applicator 10 and the second glue applicator 20 may also be staggered horizontally. This staggered arrangement allows for separate or simultaneous glue application to the glue-applying surface of the frame 200. The horizontally staggered arrangement of the first glue applicator 10 and the second glue applicator 20 also avoids mutual interference between the glue applicators, facilitating adjustments to the glue application effect.

[0040] Understandably, the first glue applicator 10 and the second glue applicator 20 can apply glue separately or simultaneously, thereby significantly improving glue application efficiency and thus improving work efficiency.

[0041] Specifically, the adhesive application device 100 also includes an adhesive applicator, which is connected to both the first adhesive application head 10 and the second adhesive application head 20. The adhesive applicator supplies adhesive to both the first adhesive application head 10 and the second adhesive application head 20.

[0042] Furthermore, the first applicator head 10 has a first inlet 11 and a first outlet 12 at its two ends, respectively, with the first inlet 11 connected to the sealant of the applicator. The second applicator head 20 has a second inlet and a second outlet at its two ends, respectively, with the second inlet connected to the sealant of the applicator.

[0043] In this embodiment, both the first glue applicator 10 and the second glue applicator 20 are made of stainless steel and manufactured by precision injection molding. This makes the strength of the first glue applicator 10 and the second glue applicator 20 superior to that of conventional chucks made of nylon, ensuring that the glue head will not deform due to excessive glue dispensing pressure and ensuring glue dispensing stability and uniformity.

[0044] Specifically, the first and second glue inlets 11 and 12 are cylindrical in shape, making them compatible with most current glue applicators and improving adaptability. The first and second glue outlets 12 and 12 are designed with pinhole structures to reduce the glue output of a single applicator head and effectively increase the applicator speed.

[0045] In this embodiment, the first adhesive applicator 10 and / or the second adhesive applicator 20 are cylindrical structures. Specifically, both the first adhesive applicator 10 and the second adhesive applicator 20 are cylindrical. In other embodiments, either the first adhesive applicator 10 or the second adhesive applicator 20 may be cylindrical; no specific limitation is made here.

[0046] Understandably, the first glue applicator 10 and the second glue applicator 20 are designed as syringe-shaped cylindrical structures, which can reduce the glue output of a single glue applicator, thereby effectively increasing the glue application speed, making the glue application surface more rounded, and the glue application effect better.

[0047] Furthermore, the diameter of the first adhesive applicator 10 and / or the second adhesive applicator 20 is 1mm-5mm. In this embodiment, the diameter of the first adhesive applicator 10 and the second adhesive applicator 20 is 1mm. In other embodiments, the diameter of the first adhesive applicator 10 and the second adhesive applicator 20 may also be 2mm, 3mm, 4mm or 5mm, and no specific limitation is made here.

[0048] In addition, the adhesive application device 100 also includes a first adhesive dispensing control valve and a second adhesive dispensing control valve. The first adhesive dispensing control valve is located at the first adhesive application head 10, and the second adhesive dispensing control valve is located at the second adhesive application head 20. The first adhesive dispensing control valve controls the amount of adhesive dispensed from the first adhesive application head 10, and the second adhesive dispensing control valve controls the amount of adhesive dispensed from the second adhesive application head 20. The first and second adhesive dispensing control valves can independently control the amount of adhesive applied to the first and second adhesive application heads 10 and 20 respectively. By coordinating adhesive dispensing at different positions between the heads, the final adhesive width, thickness, and application shape of the frame 200 can be precisely controlled, improving module reliability and ensuring a stronger bond between the frame 200 and the photovoltaic module.

[0049] In this embodiment, the adhesive type of the first adhesive applicator 10 and the second adhesive applicator 20 is adhesive block 101.

[0050] The adhesive application apparatus 100 provided in this embodiment has at least the following advantages:

[0051] The adhesive application device 100 is applicable to both conventional bezels and bezels of full-screen displays without an A-side. The first adhesive application head 10 and the second adhesive application head 20 are distributed at the bottom of the groove in the bezel 200 and near the C-side of the groove, facilitating control of adhesive overflow and improving process adaptability. Specifically, the distribution of the first adhesive application head 10 and the second adhesive application head 20 at the bottom of the groove in the bezel 200 and near the C-side helps control the direction and range of silicone flow, improving adhesive overflow control and meeting the sealing requirements of component encapsulation.

[0052] The first glue applicator 10 and the second glue applicator 20 provided in this embodiment are both made of stainless steel and manufactured by precision injection molding. This makes the strength of the first glue applicator 10 and the second glue applicator 20 superior to that of conventional chucks made of existing nylon material, ensuring that the glue head will not deform due to excessive glue dispensing pressure, and ensuring glue dispensing stability and uniformity.

[0053] In summary, this utility model provides a gluing device 100 and a photovoltaic production equipment 1000. The gluing device 100 includes a first gluing head 10 and a second gluing head 20, which are staggered. The second gluing head 20 and the first gluing head 10 are used to apply glue to the gluing surface of the frame 200, either separately or simultaneously. In use, by setting the first gluing head 10 and the second gluing head 20 and staggering them in space, gluing operations can be performed on the gluing surface of the frame 200, either separately or simultaneously. Through the coordinated operation of the first gluing head 10 and the second gluing head 20, more gluing paths can be completed per unit time, significantly improving gluing efficiency and making it suitable for the automated production of large-scale photovoltaic modules. Furthermore, the first gluing head 10 and the second gluing head 20 can be controlled separately for the glue dispensing amount and speed. Combined with the staggered arrangement, the glue distribution is more uniform and consistent, avoiding the problem of uneven glue dispensing caused by pressure changes in traditional single-head gluing.

[0054] The photovoltaic production equipment 1000 includes a frame 200 and an adhesive applicator 100, which is used to apply adhesive to the frame 200. In use, by setting a first adhesive applicator 10 and a second adhesive applicator 20, and arranging them in a staggered spatial configuration, adhesive can be applied to the adhesive surface of the frame 200 separately or simultaneously.
