Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of battery cell processing equipment, and more specifically, to a battery cell coating and edge-wrapping device. Background Technology
[0002] The coating and edge-wrapping processes are important steps in the processing of solar cells. The coating process involves applying adhesive to the surface of the solar cell, while the edge-wrapping process involves wrapping the edges of the solar cell with protective material to prevent damage.
[0003] For conventional rectangular solar cells, it is necessary to wrap the four edges in the length and width directions. However, the dimensions of conventional wrapping mechanisms are fixed, which means that different wrapping mechanisms are required when wrapping the long and wide edges of the solar cells. At the same time, the conventional wrapping process and the coating process need to be carried out in two workshops, which prolongs the production time of solar cells and results in low production efficiency. Utility Model Content
[0004] The purpose of this invention is to provide a battery cell coating and edge-wrapping device that can improve the production efficiency of battery cells.
[0005] The embodiments of this utility model can be implemented as follows: In a first aspect, this utility model provides a battery cell coating and edge-wrapping device, comprising: A printing platform used to carry and transport solar cells; Edge-binding fixtures are set on both sides of the printing platform to apply adhesive to the edges of the battery cells and form an adhesive application area on the edge of the battery cells. A telescopic component is disposed on the printing platform and connected to the edge-binding clamp, for driving the edge-binding clamps on both sides of the printing platform to move closer to each other or further apart; A coating assembly is disposed above the printing platform for coating the battery cells located on the printing platform.
[0006] In an optional embodiment, the edge-binding fixture includes a glue storage box and a glue receiving box.

[0010] In an optional embodiment, rollers are provided at both ends of the printing platform, and a table roll of paper is wound between the two rollers. The rollers drive the table roll of paper to wind, so as to move the battery cell.
[0011] In an optional embodiment, the coating equipment assembly includes a coating screen and a coating blade, the coating screen being raised and lowered above the printing platform, and the coating blade being adapted to the coating screen and slidably disposed along the coating screen.
[0012] In an optional embodiment, the coating and edge-sealing equipment further includes a basket for storing the coated and edge-sealed battery cells, and the basket is connected to the printing platform via a conveyor belt.
[0013] In an optional embodiment, the flower basket includes a frame body and a plurality of support members disposed on the frame body.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0022] Furthermore, the terms "first" and "second" are used only to distinguish descriptions and should not be interpreted as indicating or implying relative importance.
[0023] 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.
[0024] In the manufacturing process of photovoltaic cells, the coating process and the edge-wrapping process are key steps. The coating process involves applying specific functional materials to the surface of the cell using physical or chemical methods, while the edge-wrapping process involves wrapping protective materials around the edges of the cell to prevent current leakage or short circuits.
[0025] For conventional rectangular solar cells, the four edges in the length and width directions need to be edge-wrapped. However, the dimensions of conventional edge-wrapping mechanisms are fixed, requiring the use of different sized mechanisms for the length and width edges of the solar cell. Furthermore, both the conventional edge-wrapping and coating processes require drying the solar cells in an oven, and the drying conditions for both processes are roughly the same. The conventional practice of separating these two processes prolongs the solar cell production time, resulting in low production efficiency.
[0026] To address the problem of low production efficiency in current solar cell manufacturing, this invention provides a solar cell coating and edge-wrapping device. The overall structure, working principle, and technical effects of the solar cell coating and edge-wrapping device provided by this invention are described in detail through embodiments and accompanying drawings.
[0027] Please refer to Figures 1-3 This invention provides a solar cell coating and edge-wrapping device for photovoltaic cell production. Specifically, it integrates the coating and edge-wrapping processes into a single operation, completing the edge-wrapping while coating and printing the solar cells, thus shortening production time. It is also suitable for edge-wrapping solar cells of different sizes. Both the long and wide edges of the solar cells can be wrapped on the same device, making operation convenient and improving production efficiency.
[0028] For details, please refer to Figure 1 and Figure 2The battery cell coating and edge-wrapping equipment provided by this utility model includes a printing platform 100, edge-wrapping clamps 200, a telescopic component 300, and a coating component 400. The printing platform 100 is used to carry and transport the battery cells, and also serves as a support platform during the battery cell coating process. The edge-wrapping clamps 200 are disposed on both sides of the printing platform 100, and the telescopic component 300 is disposed on the printing platform 100 and connected to the edge-wrapping clamps 200. The telescopic component 300 is used to drive the edge-wrapping clamps 200 on both sides of the printing platform 100 to move closer or further apart. Thus, during the edge-wrapping process of the battery cells, the battery cells are transported through the printing platform 100 to between the two edge-wrapping clamps 200. The telescopic component 300 drives the two edge-wrapping clamps 200 to move closer together until they abut against the battery cells, and the edge-wrapping clamps 200 perform edge-wrapping processing on the edges of the battery cells. The coating assembly 400 is positioned above the printing platform 100. While the battery cell is being edge-wrapped on the printing platform 100, the coating assembly 400 coats the upper surface of the battery cell.
[0029] By setting the telescopic component 300 to drive the two edge-wrapping clamps 200 to move closer or further apart, the spacing between the two edge-wrapping clamps 200 can be adaptively adjusted, which can be applied to battery cells of different widths and to the long and wide edges of the same battery cell. At the same time, the coating component 400 is set above the printing platform 100, and the battery cell is coated while being edge-wrapped. There is no need to coat and edge-wrap the battery cells separately in different workshops, which shortens the production time of the battery cells and improves the production efficiency of the battery cells.
[0030] Please refer to Figure 1 and Figure 2 Specifically, in an optional embodiment, the edge-binding fixture 200 includes a glue storage box 210 and a glue receiving box 220. The glue storage box 210 is a rectangular box arranged along the length of the printing platform 100. A glue inlet 211 for glue injection is provided at the top of the glue storage box 210. Edge-binding glue grooves 212 are provided on opposite sides of the two glue storage boxes 210, wherein the length direction of the edge-binding glue grooves 212 is consistent with the length direction of the glue storage box 210. The glue receiving box 220 is a box with an open top, located below the glue storage box 210 and the printing platform 100. Glue leaking during the edge-binding process drips into the glue storage box 210 for collection and storage. The telescopic component 300 is connected to the glue storage box 210 and is used to drive the two glue storage boxes 210 closer together or further apart.
[0031] Understandably, during the edge-wrapping process of the solar cell, the solar cell is placed on the printing platform 100. The telescopic component 300 drives two glue storage boxes 210 to move closer together until the sides of the solar cell are placed into the edge-wrapping glue groove 212. The glue storage box 210 contains glue, and the glue overflows from the edge-wrapping glue groove 212. The width of the edge-wrapping glue groove 212 is set according to the edge-wrapping requirements, and the overflow rate of the glue is just right to meet the edge-wrapping requirements. The glue overflowing from the edge-wrapping glue groove 212 flows into the glue receiving box 220 below for storage.
[0032] Please refer to Figure 1 and Figure 2 In some optional embodiments, the telescopic assembly 300 includes a telescopic cylinder 310, which is provided on both sides of the printing platform 100. The cylinder body of the telescopic cylinder 310 is mounted on the printing platform 100, and the piston rod of the telescopic cylinder 310 extends away from the printing platform 100 and is connected to the glue storage box 210, thereby activating the telescopic cylinder 310. By controlling the extension or retraction of the piston rod of the telescopic cylinder 310, the glue storage boxes 210 on both sides of the printing platform 100 can be moved closer or further apart to accommodate battery cells of different sizes and to fit the long and wide edges of the battery cells. In other optional embodiments, the telescopic assembly 300 can also be a structure such as an electric push rod or a crank rocker that can drive the glue storage box 210 to perform linear reciprocating motion.
[0033] Please refer to Figure 1 and Figure 2 In some optional embodiments, a return port 221 is provided at the bottom of the glue receiving box 220. The return port 221 is connected to a return pipe for recycling the glue collected and stored in the glue receiving box 220, thereby saving costs and reducing waste.
[0034] Please refer to Figure 1 and Figure 2 When the battery cell is located on the printing platform 100, in order to facilitate the fixing of the battery cell and prevent the battery cell from shifting during the edge wrapping and coating process, in some optional embodiments, a plurality of vacuum holes 110 are provided on the printing platform 100. When the battery cell is located on the printing platform 100, the vacuum holes 110 adsorb and fix the battery cell, thereby achieving the effect of fixing the battery cell.
[0035] Furthermore, in order to drive the solar cells to move on the printing platform 100, so as to move the solar cells to the processing position and remove the processed solar cells from the printing platform 100, please refer to... Figure 1 and Figure 2In some optional embodiments, rollers 120 are provided at both ends of the printing platform 100, with the length direction of the rollers 120 along the width direction of the printing platform 100, and a table roll paper 130 is wound between the two rollers 120. By driving the two rollers 120 to rotate, the table roll paper 130 is driven to move while winding, thereby moving the battery cell located on the table roll. It is understood that the table roll paper 130 is attached to the printing platform 100, and because the table roll paper 130 itself has tiny gaps, when the battery cell is located on the printing platform 100, the adsorption force of the vacuum holes 110 can act on the battery cell through the table roll paper 130, and the table roll paper 130 does not affect the fixing effect of the vacuum holes 110 on the battery cell.
[0036] Please refer to Figure 1 and Figure 2 In some optional embodiments, the coating equipment includes a coating screen 410 and a coating blade 420. The coating screen 410 is located directly above the printing platform 100 and is vertically adjustable. The coating blade 420 is positioned on one side of the coating screen 410. When the battery cell to be processed is located on the printing platform 100, the coating screen 410 moves to fit against the battery cell, and the coating blade 420 slides along the coating screen 410 to coat the battery cell. The application of adhesive and printing operations on the coating screen 410 employ existing coating processes, which are not limited herein.
[0037] Please refer to Figure 3 The battery cell coating and edge-wrapping equipment provided by this utility model also includes a basket 500, which is used to store the coated and edge-wrapped battery cells. The battery cells are connected to the printing platform 100 by a conveyor belt. The battery cells that have undergone edge-wrapping and coating processing on the printing platform 100 are transported to the basket 500 by the conveyor belt and stored in the basket 500.
[0038] Please refer to Figure 3 In some optional embodiments, the edge of the battery cell has an adhesive coating area, which is the area where the edge-wrapping clamp 200 performs edge-wrapping adhesive processing on the edge of the battery cell. The flower basket 500 includes a frame body 510 and several support members 520 mounted on the frame body 510. Each support member 520 includes a connecting portion 521 and an abutting portion 522. One end of the connecting portion 521 is connected to the frame body 510, and the abutting portion 522 is connected to the other end of the connecting portion 521. When the battery cell is placed on the flower basket 500, the abutting portion 522 abuts and supports the battery cell. The distance between the abutting portion 522 and the frame body 510 is greater than the width of the edge-wrapping area of the battery cell, thereby preventing the edge-wrapping adhesive coating area of the battery cell from contacting the flower basket 500 when the battery cell is placed on it, which would result in missing adhesive in the edge-wrapping area and affect the performance of the battery cell.
[0039] In summary, the implementation principle of the battery cell coating and edge-wrapping equipment provided by this utility model is as follows: by setting the telescopic component 300 to drive the edge-wrapping clamps 200 on both sides to move closer or further apart, the spacing between the edge-wrapping clamps 200 on both sides can be adaptively adjusted, which can be applied to battery cells of different widths and to the long and wide edges of the same battery cell; at the same time, the coating component 400 is set above the printing platform 100, and the battery cell is coated while the edge-wrapping process is being performed; there is no need to perform coating and edge-wrapping processes on the battery cells in different workshops, which shortens the production time of the battery cells and improves the production efficiency of the battery cells.
[0040] The above description is only a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes 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.
