Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic cell manufacturing, and particularly relates to a novel glue coating device for battery chips. Background Art

[0002] In the production process of photovoltaic cells, a protective layer needs to be coated on the edges of the battery chips to prevent the sides of the battery chips from being electroplated. Generally, glue needs to be coated on the four sides and the chamfer edges in the length and width directions respectively. In the prior art, either single-sided coating is carried out, or it is divided into two steps, first coating the long sides and then the short sides, or first coating the short sides and then the long sides. If special chamfers are involved, the chamfers need to be coated separately. During this process, not only a rotating structure is required to change the direction of the battery chip, but also an expensive vision detection system or a robotic arm is needed to push the battery chip to the glue coating station, resulting in a long coating time and low efficiency. Therefore, a novel glue coating device for battery chips is needed to solve the above technical problems. Content of the Utility Model

[0003] The problem to be solved by the utility model is to provide a novel glue coating device for battery chips, which can coat the four sides of the battery chip simultaneously and can be actively adjusted according to the position of the battery chip, saving costs and improving efficiency.

[0004] To solve the above technical problems, the technical solution adopted by the utility model is: a novel glue coating device for battery chips, which can be in contact with the battery chip, includes a fixed frame and a glue coating mechanism slidably connected to the fixed frame. The glue coating mechanism encloses a space and can simultaneously contact the four side edges of the battery chip for glue coating.

[0005] Further, the glue coating mechanism includes a lifting plate, a first glue coating mechanism symmetrically arranged on both sides of the lifting plate and rotatably connected to the lifting plate, and a second glue coating mechanism symmetrically arranged on the other two sides of the lifting plate and rotatably connected to the lifting plate. Driving the lifting plate can simultaneously drive the first glue coating mechanism and the second glue coating mechanism to perform an opening and closing movement to form the space.

[0006] Further, a guide post perpendicular to the lifting plate is slidably arranged on the lifting plate to limit the lateral movement of the lifting plate.

[0007] Further, a lead screw is arranged at the center of the lifting plate. Driving the lead screw can drive the lifting plate to move up and down, and further drive the first glue coating mechanism and the second glue coating mechanism to perform an opening and closing movement.

[0008] Further, the first glue coating mechanism includes a first glue coating connecting rod, a first roller bracket and a first roller. One end of the first glue coating connecting rod is connected to the lifting plate, and the other end is connected to the first roller through the first roller bracket. The three form a first link mechanism with the lifting plate.

[0009] Further, the second glue - applying mechanism includes a second glue - applying connecting rod, a second roller bracket, and a second roller. One end of the second glue - applying connecting rod is connected to the lifting plate, and the other end is connected to the second roller through the second roller bracket. The three of them and the lifting plate form a second link mechanism.

[0010] Further, the first roller bracket is slidably connected to the fixed frame through a first slider, and the second roller bracket is slidably connected to the fixed frame through a second slider.

[0011] Further, the first roller is connected to the first roller bracket through a first scraper, and the second roller is connected to the second roller bracket through a second scraper. Adjusting the first scraper and the second scraper can change the thickness of the glue on the surfaces of the first roller and the second roller.

[0012] Further, the first roller and the second roller are immersed in the glue - applying tank to coat the glue in the glue - applying tank on their surfaces.

[0013] Further, a lifting mechanism is provided on the side of the fixed frame away from the lifting plate. Driving the lifting mechanism can move the battery cell from the conveying mechanism to the position of the center tangent of the first roller and the second roller.

[0014] With the above - mentioned technical solutions, a lifting plate and the first and second glue - applying mechanisms rotatably connected thereto are provided. The four glue - applying mechanisms and the lifting plate are combined into four link mechanisms, which drive the four rollers to perform an opening - and - closing movement simultaneously, enabling the rollers to actively contact the battery cell for coating without changing the existing transportation structure, reducing the equipment cost; by controlling the sizes of the four rollers and the thickness of the glue on them, the coating width and thickness of battery cells of different specifications can be achieved, improving the glue - applying efficiency and quality; through the cooperation of the lifting mechanism and the positions of the four rollers, the rollers can be quickly adjusted to actively contact the side of the battery cell, realizing the uniform thickness consistency during the glue - applying of the battery cell to ensure the glue - applying quality; the device can be matched according to the positions of the feeding, discharging, and conveying mechanisms, with more accurate positioning and higher automation.

[0024] It is easy to understand that according to the technical solution of the present utility model, without changing the essence of the present utility model, those of ordinary skill in the art can propose various interchangeable structural forms and implementation manners. Therefore, the following specific implementation manners and the accompanying drawings are only exemplary descriptions of the technical solution of the present utility model, and should not be regarded as the whole of the present utility model or as a limitation or restriction on the technical solution of the present utility model.

[0025] The orientation terms such as up, down, left, right, top, bottom, etc. mentioned or possibly mentioned in this specification are defined relative to the structures shown in the respective drawings. They are relative concepts, and thus may change accordingly depending on their different positions and different usage states. Therefore, these or other orientation terms should not be interpreted as restrictive terms.

[0026] As Figure 1 and Figure 2 shown, a new - type battery - cell glue - applying device can contact the battery cell 6, and includes a fixed frame 1 and a glue - applying mechanism 2 slidably connected to the fixed frame 1. The glue - applying mechanism 2 encloses a space and can simultaneously contact the four sides of the battery cell 6 for glue - applying.

[0027] Preferably, the glue - applying mechanism 2 includes a lifting plate 223, a first glue - applying mechanism 211 symmetrically arranged on both sides of the lifting plate 223 and rotatably connected to the lifting plate 223, and a second glue - applying mechanism 212 symmetrically arranged on the other two sides of the lifting plate 223 and rotatably connected to the lifting plate 223. Driving the lifting plate 223 can simultaneously drive the first glue - applying mechanism 211 and the second glue - applying mechanism 212 to perform an opening - and - closing movement to form a space. As Figure 3 shown, the first glue - applying mechanism 211 and the second glue - applying mechanism 212 are arranged at intervals in the circumferential direction of the lifting plate 223, and can approach or move away from the side of the battery cell 6 as the lifting plate 223 moves up and down.

[0028] Preferably, guide posts 224 perpendicular to it are slidably arranged on the lifting plate 223 to limit the lateral movement of the lifting plate 223. In this embodiment, a plurality of guide posts 224 are circumferentially arranged on the lifting plate 223, and they are all parallel to the lead screw 225, so that the lifting plate 223 can only move longitudinally and cannot move laterally. A driving motor is provided at the bottom of the lead screw 225.

[0029] Preferably, a lead screw 225 is provided at the center of the lifting plate 223. Driving the lead screw 225 can drive the lifting plate 223 to move up and down, and further drive the first glue - applying mechanism 211 and the second glue - applying mechanism 212 to perform an opening - and - closing movement.

[0030] Preferably, as Figure 4 shown, the first glue - applying mechanism 211 includes a first glue - applying connecting rod 2113, a first roller bracket 2111, and a first roller 2112. One end of the first glue - applying connecting rod 2113 is connected to the lifting plate 223, and the other end is connected to the first roller 2112 through the first roller bracket 2111. The three form a first link mechanism with the lifting plate 223.

[0031] Preferably, the second glue - applying mechanism 212 includes a second glue - applying connecting rod 2123, a second roller bracket 2121, and a second roller 2122. One end of the second glue - applying connecting rod 2123 is connected to the lifting plate 223, and the other end is connected to the second roller 2122 through the second roller bracket 2121. The three form a second link mechanism with the lifting plate 223.

[0032] Preferably, the first roller bracket 2121 is slidably connected to the fixed frame 1 through a first slider 112, and the second roller bracket 2121 is slidably connected to the fixed frame 1 through a second slider 113.

[0033] Preferably, the first roller 2112 is connected to the first roller bracket 2111 through a first scraper 227, and the second roller 2122 is connected to the second roller bracket 2121 through a second scraper 229. Adjusting the first scraper 227 and the second scraper 229 can change the thickness of the glue on the surfaces of the first roller 2112 and the second roller 2122.

[0034] Preferably, the first roller 2112 and the second roller 2122 are immersed in the glue coating tank 228 to coat the glue in the glue coating tank 228 on their surfaces. In this embodiment, by rotating the first roller 2112 and the second roller 2122, the glue in the glue coating tank 228 is coated on their surfaces. The squeegee contacts the surface of the roller and can be displaced along the length direction of the roller body. By moving the squeegee, the glue with an excessive thickness can be scraped off to meet the coating requirements of the battery wafers. It should be noted that the two squeegees are arranged on the corresponding roller brackets and are connected by a driving cylinder. As the telescopic rod of the driving cylinder extends and retracts, the squeegee is driven to displace along the length direction of the roller body, so that the excessive glue can be scraped off faster, improving the glue coating quality. At the same time, the excessive glue flows back into the glue coating tank 228, improving the utilization rate of the glue and saving resources.

[0035] Preferably, a lifting mechanism 4 is provided on the side of the fixing frame 1 away from the lifting plate 223. Driving the lifting mechanism 4 can move the battery wafer 6 from the conveying mechanism 3 to the position of the central tangent of the first roller 2112 and the second roller 2122. In this embodiment, the lifting mechanism 4 is arranged below the fixing frame 1 and distributed on the side of the conveying mechanism 3. The fixing frame 1 can be moved and adjusted to be fixed near the transportation route, which is more flexible and will not be further limited here. As Figure 5 and Figure 6 shown, the lifting mechanism 4 includes a motor fixing seat 413, a battery wafer lifting plate 411 and a battery wafer lifting motor 412. The battery wafer lifting motor 412 is fixed on the motor fixing seat 413 and connected to the battery wafer lifting plate 411. Driving the battery wafer lifting motor 412 can push the battery wafer lifting plate 411 to move upward, thereby pushing the battery wafer 6 away from the conveying mechanism 3. When the glue coating task is completed, the battery wafer lifting plate 411 can be driven to descend, driving the battery wafer 6 to descend and be placed on the conveying mechanism 3 again to continue the next process.

[0036] Embodiment 1:

[0037] This embodiment provides a new type of battery wafer glue coating device that can contact the battery wafer 6, including a fixing frame 1, a glue coating mechanism 2 slidably connected to the fixing frame 1, a conveying mechanism 3, and a lifting mechanism 4 connected to the conveying mechanism 3. The lifting mechanism 4 can lift the battery wafer 6 into the space surrounded by the glue coating mechanism 2 and make the glue coating mechanism 2 physically contact the side of the battery wafer 6 for glue coating.

[0038] As Figure 1As shown in the figure, the glue - applying mechanism 2 includes a lifting plate 223, a first glue - applying mechanism 211 symmetrically arranged on both sides of the lifting plate 223, and a second glue - applying mechanism 212 symmetrically arranged on the other two sides of the lifting plate 223. The first glue - applying mechanism 211 and the second glue - applying mechanism 212 enclose the battery cell 6 in sequence at intervals for glue - applying. Both the first glue - applying mechanism 211 and the second glue - applying mechanism 212 are rotatably connected to the lifting plate 223.

[0039] A lead screw 225 thread - connected to the middle of the lifting plate 223 is provided. The lead screw is connected to a driving motor 226. Guide columns 224 are circumferentially arranged on the lifting plate 223. The guide columns 224 are perpendicular to the lifting plate 223 and can slide relative to each other.

[0040] As Figure 2 shown, the first glue - applying mechanism 211 includes a first glue - applying connecting rod 2113, a first roller support 2111, and a first roller 2112. The lifting plate 223, the first glue - applying connecting rod 2113, the first roller support 2111, and the first roller 2112 are sequentially connected to form a first connecting rod mechanism, that is, a long - side connecting rod mechanism. As the lifting plate 223 moves up and down, the first rollers 2112 on both sides are driven to approach or move away from each other. Similarly, the second glue - applying mechanism 212 includes a second glue - applying connecting rod 2123, a second roller support 2121, and a second roller 2122. The lifting plate 223, the second glue - applying connecting rod 2123, the second roller support 2121, and the second roller 2122 are sequentially connected to form a second connecting rod mechanism, that is, a short - side connecting rod mechanism. As the lifting plate 223 moves up and down, the second rollers 2122 on both sides are driven to approach or move away from each other.

[0041] The fixing frame 1 is provided with a first through - hole. The first roller support 2111 passes through the first through - hole and is connected to the lifting plate 223 through the first glue - applying connecting rod 2113. The end of the first roller support 2111 away from the first through - hole is connected to the first roller 2112. As Figure 2 shown, a first guide rail 111 is provided at the bottom of the fixing frame 1. A first slider 112 is arranged in the first guide rail 111, and it is slidably connected to the first roller support 2111 through the first slider 112. As the first slider 112 slides in the first guide rail 111, the first rollers 2112 on both sides are driven to approach or move away from each other.

[0042] The fixing frame 1 is provided with a second through - hole. The second roller support 2121 passes through the second through - hole and is connected to the lifting plate 223 through the second glue - applying connecting rod 2123. The end of the second roller support 2121 away from the second through - hole is connected to the second roller 2122. As Figure 1As shown in the figure, the bottom of the fixing frame 1 is provided with a second guide rail 114. A second slider 113 is arranged in the second guide rail 114, and it is slidably connected with the second roller bracket 2121 through the second slider 113. As the second slider 113 slides in the second guide rail 114, the second rollers 2122 on both sides are driven to approach or move away from each other.

[0043] As Figure 4 shown in the figure, the driving motor 226 drives the lead screw 225 to rotate. Under the limiting action of the guide post 224, the lifting plate 223 moves up and down under the acting force. The first slider 112 slides along the first guide rail 111, and the second slider 113 slides along the second guide rail 114, so that the four rollers move in an opening and closing manner. When the driving motor 226 drives the lead screw 225 to rotate clockwise, the lifting plate 223 moves upward, driving the first roller brackets 2111 on both sides to approach each other through the first glue coating connecting rod 2113. At the same time, the second roller brackets 2121 on both sides are driven to approach each other through the second glue coating connecting rod 2123, so that the two first rollers 2112 and the two second rollers 2122 approach each other to contact the four sides of the battery sheet 6. When the lifting plate 223 moves downward, the same is true, driving the two first rollers 2112 and the two second rollers 2122 to move away from each other, which will not be repeated here.

[0044] During operation, the long-side electric rollers (i.e., the first rollers 2112) and the short-side electric rollers (i.e., the second rollers 2122) continuously rotate to adhere the glue in the glue coating tank 228 to their surfaces. At the same time, under the action of the scraper 227, the glue on the surfaces of the first rollers 2112 and the second rollers 2122 reaches the thickness required by the process.

[0045] When the battery sheet 6 reaches the predetermined position through the conveying mechanism 3, the first glue coating mechanism 211 and the second glue coating mechanism 212 stop operating. The battery sheet lifting motor 412 drives the battery sheet lifting plate 411 to rise, lifting the battery sheet 6 to the center tangent position of the first rollers 2112 and the second rollers 2122. When the driving motor 226 drives the lifting plate 223 to move up and down, it drives the first glue coating mechanism 211 and the second glue coating mechanism 212 to move in an opening and closing manner. When reaching the predetermined position, the battery sheet 6 physically contacts the sides of the battery sheet 6 through the surfaces of the first rollers 2112 and the second rollers 2122 for glue coating, so as to realize the function of simultaneous glue coating on the long side and the short side.

[0046] The beneficial effects of the present utility model are as follows: By providing a lifting plate and a first glue coating mechanism and a second glue coating mechanism rotatably connected thereto, the four glue coating mechanisms and the lifting plate are combined into four link mechanisms, which drive the four rollers to perform opening and closing movements simultaneously, enabling the rollers to actively contact the battery cells for coating without changing the existing transportation structure, thus reducing the equipment cost; By controlling the sizes of the four rollers and the thickness of the glue applied thereon, the coating width and thickness of battery cells of different specifications can be achieved, improving the glue coating efficiency and quality; Through the cooperation of the lifting mechanism and the positions of the four rollers, the rollers can be quickly adjusted to actively contact the sides of the battery cells, realizing uniform thickness consistency during the glue coating of the battery cells to ensure the glue coating quality; This device can be matched according to the positions of the loading, unloading, and conveying mechanisms, with more accurate positioning and improved automation level.

[0047] The above has described the embodiments of the present utility model in detail, but the content described is only the preferred embodiments of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made according to the scope of the application of the present utility model should still fall within the scope covered by the patent of the present utility model.
