Detailed Implementation
[0028] In related technologies, a single-layer design can only process one silicon wafer at a time, resulting in low encapsulation efficiency and affecting the production efficiency of solar cells.
[0029] To address the aforementioned problems, this utility model provides a coating device and a coating system that can process multiple solar cells simultaneously, greatly improving coating efficiency and solar cell production efficiency.
[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0033] In the description of this utility model, it should be noted that if terms such as "upper," "lower," "inner," or "outer" are used to indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product is usually placed during use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.
[0034] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0035] 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.
[0036] The following describes in detail the overall structure, working principle, and technical effects of the coating device 10 and coating system provided by this utility model through embodiments and in conjunction with the accompanying drawings.
[0037] Please refer to Figure 1 and Figure 2 This utility model provides a coating device 10, applied to a coating system, capable of processing multiple solar cells simultaneously, greatly improving coating efficiency and solar cell production efficiency. The coating device 10 includes a first end cap 100, a second end cap 300, a separator component 200, and a glue dispensing component 400. The second end cap 300 and the first end cap 100 are disposed opposite each other in a predetermined direction, and the separator component 200 is located between the first end cap 100 and the second end cap 300.
[0038] Based on the above, the glue dispensing assembly 400 includes a first glue dispensing wheel 410 and a second glue dispensing wheel 420. The first glue dispensing wheel 410 connects to the separator assembly 200 and the first end cap 100, and together with the first end cap 100 and the separator assembly 200, forms a first glue dispensing chamber. Correspondingly, the second glue dispensing wheel 420 connects to the separator assembly 200 and the second end cap 300, and together with the second end cap 300 and the separator assembly 200, forms a second glue dispensing chamber.
[0039] In other words, based on the isolation configuration of the separator component 200, it is ensured that the first and second dispensing chambers can perform independent dispensing operations for different solar cells. Therefore, the dispensing apparatus 10 provided in this application allows for the simultaneous processing of multiple solar cells, significantly improving dispensing efficiency and overall production efficiency. Compared to traditional single-chamber equipment, it shortens the production cycle, reduces waiting time, and ensures continuous operation of the production line.
[0040] Furthermore, when the first and second dispensing chambers are interconnected, the first end cap 100 has a first opening 110 communicating with the first dispensing chamber, or the second end cap 300 has a second opening 310 communicating with the second dispensing chamber. Based on this, glue can be injected into both the first and second dispensing chambers through the first opening 110 / second opening 310. To facilitate the backflow of excess glue, the first end cap 100 may have a first opening 110 communicating with the first dispensing chamber, and the second end cap 300 may have a second opening 310 communicating with the second dispensing chamber. Based on this, one of the first opening 110 and the second opening 310 serves as a glue inlet, and the other as a glue outlet.
[0041] In addition, when the first dispensing chamber and the second dispensing chamber are independent of each other, the first end cap 100 is provided with a first opening 110 communicating with the first dispensing chamber, and the second end cap 300 is provided with a second opening 310 communicating with the second dispensing chamber, so as to ensure that glue is injected into both dispensing chambers.
[0042] To ensure the stable structural integrity of the entire coating device 10 during operation, the coating device 10 also includes fasteners. These fasteners sequentially connect the first end cap 100, the first dispensing wheel 410, the separator component 200, the second dispensing wheel 420, and the second end cap 300 along a predetermined direction. Optionally, the fasteners are screws, which pass through the corresponding screw locking holes provided on the aforementioned components to achieve the connection. Each component may have four screw locking holes, evenly spaced along the circumference.
[0043] In addition, it should be noted that fasteners can apply appropriate clamping force to ensure that the contact surfaces between the components fit tightly, thereby improving the sealing performance of the overall device, preventing glue leakage, and ensuring the smooth progress of the encapsulation process.
[0044] like Figure 2 As shown, in the coating device 10, the first dispensing roller 410 has at least two first dispensing holes 411 spaced apart circumferentially. In practical applications, multiple first dispensing holes 411 can dispense adhesive simultaneously, uniformly applying sufficient adhesive to the battery cells in a short time, thereby significantly shortening the coating time for each battery cell and improving overall production capacity. Correspondingly, the second dispensing roller 420 has at least two second dispensing holes 421 spaced apart circumferentially. The design principle and beneficial effects are similar to those described above and will not be repeated here.
[0045] Furthermore, the first dispensing hole 411 extends circumferentially along the first dispensing roller 410, and / or the second dispensing hole 421 extends circumferentially along the second dispensing roller 420. Taking the first dispensing hole 411 as an example, the first dispensing hole 411 extends circumferentially along the first dispensing roller 410 to form a linear dispensing channel, which can form a continuous and uniform glue flow on the surface of the solar cell. Compared with dot-shaped dispensing holes, linear dispensing can provide a wider coverage area, ensuring that the glue is evenly distributed on the solar cell.
[0046] Additionally, it should be noted that the first and second adhesive outlet holes 411 and 421 are designed to avoid interference with the screw locking holes in the aforementioned embodiments to prevent adhesive leakage from the screw locking holes. Furthermore, a certain height is reserved between the first and second adhesive outlet holes 411 and the bottom walls of the first and second adhesive outlet chambers, respectively, to ensure that a certain amount of adhesive remains in the first / second adhesive outlet chamber while the adhesive flows downwards, preventing adhesive breakage.
[0047] Please see Figures 2 to 4 The separating assembly 200 further includes at least one first separating disc 210 and at least one second separating disc 230, with the first separating disc 210 and the second separating disc 230 alternately arranged. Exemplarily, when there is only one first separating disc 210 and one second separating disc 230, one of the first separating disc 210 and the second separating disc 230 is connected to the first dispensing roller 410, and the other is connected to the second dispensing roller 420; when there are two first separating discs 210 and one second separating disc 230, the two first separating discs 210 are respectively connected to the first dispensing roller 410 and the second dispensing roller 420; when there is one first separating disc 210 and two second separating discs 230, the two second separating discs 230 are respectively connected to the first dispensing roller 410 and the second dispensing roller 420.
[0048] Based on the above, the dispensing assembly 400 further includes a third dispensing roller 430. The third dispensing roller 430 connects to adjacent first separators 210 and second separators 230, and together with the adjacent first separators 210 and second separators 230, forms a third dispensing chamber. Similar to the above, the third dispensing chamber can perform independent dispensing operations for different solar cells. Furthermore, depending on the number of first separators 210 and second separators 230, the third dispensing chamber can be one, two, or more, adapting to the production requirements of different solar cell production lines. In addition, the third dispensing roller 430 can, as in the aforementioned embodiment, be provided with a plurality of third dispensing holes 431 extending circumferentially at intervals.
[0049] Furthermore, the first partition plate 210 is provided with at least one first through hole 211, and the second partition plate 230 is provided with at least one second through hole 231. Based on this, the first dispensing chamber, the second dispensing chamber, and the third dispensing chamber are connected through the first through hole 211 and the second through hole 231. It is easy to understand that connecting multiple dispensing chambers through the through holes allows for coordinated glue flow between different chambers, ensuring that the entire system can perform the coating operation efficiently and synchronously.
[0050] With the first partition plate 210 and the second partition plate 230 alternately arranged, the projections of any first through hole 211 and second through hole 231 on a preset plane are staggered to effectively prevent glue from flowing directly from the upper layer to the lower layer, thus avoiding glue breakage. The preset plane is a plane perpendicular to a preset direction. Furthermore, the total area of all first through holes 211 is equal to the total area of all second through holes 231 to balance the glue flow between the glue outlet chambers of each layer, preventing excessive or insufficient flow in any one layer, which could lead to blockage or waste.
[0051] Alternatively, as an optional embodiment, the first dispensing roller 410, the second dispensing roller 420, and the third dispensing roller 430 have the same shape and structure, allowing for mass production and interchangeable use, thus reducing production costs. The diameters of the first end cap 100, the second end cap 300, the first spacer, and the second spacer can be different to accommodate different widths of edging requirements, improving the versatility of the device. Optionally, the ratio of the smaller diameter of the first spacer to the larger diameter of the second spacer ranges from 0.9 to 1.
[0052] In summary, this utility model provides a coating device 10, including a first end cap 100, a second end cap 300, a separator assembly 200, and a coating dispensing assembly 400. The coating dispensing assembly 400 includes a first dispensing wheel 410 and a second dispensing wheel 420. The first dispensing wheel 410 connects the separator assembly 200 and the first end cap 100, and together with the first end cap 100 and the separator assembly 200, forms a first dispensing chamber. Correspondingly, the second dispensing wheel 420 connects the separator assembly 200 and the second end cap 300, and together with the second end cap 300 and the separator assembly 200, forms a second dispensing chamber. Based on the isolation provided by the separator assembly 200, the first and second dispensing chambers can perform independent coating operations for different battery cells. Therefore, the coating device 10 provided by this application allows for the simultaneous processing of multiple battery cells, greatly improving coating efficiency and overall production efficiency. Compared to traditional single-chamber equipment, it shortens the production cycle, reduces waiting time, and ensures continuous operation of the production line.
[0053] In addition, this utility model also provides a coating system, which includes a glue dispensing device and the coating device 10 in the aforementioned embodiments. To provide a stable glue supply to each chamber, the glue dispensing device is connected to both the first and second glue dispensing chambers. It is readily understood that this coating system can also simultaneously process multiple solar cells, improving coating efficiency and solar cell production efficiency; further details will not be elaborated here.
[0054] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model.
