Description

Technical Field

[0001] The present application relates to the field of photovoltaic processing, and in particular to a carrier. Background Art

[0002] Photovoltaic cells are the core of solar photovoltaic power generation systems, and their performance plays a decisive role in the power generation efficiency of the entire system. In photovoltaic cells, welding strips and grid lines are two crucial components. Grid lines are located on the surface of the cells, and their main function is to collect and transmit photogenerated carriers. Photogenerated carriers are charges generated inside the cells through the photoelectric effect. They carry current and are the key to converting solar energy into electrical energy. The design and optimization of grid lines are crucial to improving the current collection efficiency of cells and reducing resistance losses. The welding strips are responsible for connecting the grid lines of each cell to achieve series and parallel output of current. Through precise alignment and welding, the welding strips ensure that the current can be smoothly exported from the cell, and through series and parallel combination, a larger current and voltage output is formed to meet the needs of the photovoltaic power generation system.

[0003] In the prior art, the precise alignment of the welding tape and the grid wire is crucial. Once the welding tape and the grid wire are not precisely aligned, the current transmission will be blocked, the resistance loss will increase, and the power generation efficiency and stability of the photovoltaic cell will be seriously affected. Generally, in the production process of solar cell drum winding welding tape, a carrier surface usually adsorbs multiple cells, and each cell has hundreds of grid wires. Especially in the processing of a large number of grid wires and welding tapes, it is difficult to align the grid wires on the cell with the welding tapes. Once the welding tape and the grid wire are not precisely aligned, the current transmission will be blocked, the resistance loss will increase, and the power generation efficiency and stability of the photovoltaic cell will be seriously affected.

[0004] Therefore, the technical problem of the prior art is that the quality of the battery cells is relatively poor. Utility Model Content

[0037] The embodiments of the present application provide a solution to the technical problem of poor quality of battery cells, thereby achieving a technical effect that is beneficial to improving the quality of battery cells.

[0038] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific embodiments described here are only used to explain the present application and are not used to limit the present application.

[0039] In the photovoltaic industry, the photovoltaic cell 100 is the core of the solar photovoltaic power generation system, and its performance plays a decisive role in the power generation efficiency of the entire system. In the production process of the photovoltaic cell 100, the precise alignment technology of the welding ribbon 120 and the grid line 110 is particularly important. This is not only related to the current collection efficiency and resistance loss of the cell 100, but also directly affects the overall performance and stability of the photovoltaic power generation system; Figure 1 As shown, the gate line 110 is located on the surface of the cell 100, and its main function is to collect and transmit photogenerated carriers. Photogenerated carriers are electric charges generated inside the cell 100 through the photoelectric effect. They carry current and are the key to converting solar energy into electrical energy. Therefore, the design and optimization of the gate line 110 is crucial to improving the current collection efficiency of the cell 100 and reducing resistance loss.

[0040] However, in the actual production process, the precise alignment of the welding strip 120 and the grid line 110 is a technical problem. Especially when a plurality of battery cells 100 are adsorbed on a carrier surface at the same time, and hundreds of grid lines 110 are distributed on each battery cell 100, the alignment of the welding strip 120 and the grid line 110 becomes particularly complicated and difficult. Although the general positioning mechanism drives the outlet guide wheel to run at a speed synchronized with the spacing of the grid lines 110 of the battery cell 100 through a linear motor, during the high-speed operation, due to the influence of various factors such as mechanical vibration and material properties, it is often difficult to ensure accurate alignment of the welding strip 120 and the grid line 110. In the processing of the round welding strip 120, the deviation phenomenon of the welding strip 120 is more serious, because the round welding strip 120 is welded along a certain curved path, and the welding strip 120 may be affected by various external forces during the process of traveling, causing it to deviate from the predetermined trajectory. This will not only affect the alignment accuracy of the welding strip 120 and the grid line 110, but may also cause inaccurate solder joint positions, thereby affecting the performance of the battery cell 100.

[0041] In order to solve this problem, the positioning mechanism and control system can be improved to improve their ability to perceive and adjust the positions of the welding strip 120 and the grid line 110. For example, a more accurate sensor and algorithm can be used to monitor the position information of the welding strip 120 and the grid line 110 in real time, and the running speed and position of the wire guide wheel can be adjusted through a feedback mechanism to achieve accurate alignment of the welding strip 120 and the grid line 110. Therefore, it is urgent to propose an effective method or structure to optimize or solve the problem of difficulty in aligning the welding strip 120 and the grid line 110, so as to improve the quality of the battery cell 100.

[0042] This application proposes a carrier, such as Figure 2 As shown, the processing of the welding strip 120 for the battery cell 100 includes a carrier body 200 and a limiting assembly 300 . The carrier body 200 is used to carry the battery cell 100 ; the limiting assembly 300 is used to limit the welding strip 120 .

[0043] The carrier body 200, such as Figure 2 , 3As shown, the carrier body 200 is used to carry the battery cell 100. A carrying area 210 is provided on the carrier body 200, and the carrying area 210 is used to carry the battery cell 100. Generally, the carrying area 210 temporarily fixes the battery cell 100 by adsorption, bonding, etc. The battery cell 100 is located on the carrying area 210 for processing the welding strip 120. After the welding strip 120 is processed, the battery cell 100 can be removed. It can be understood that the battery cell 100 is provided with a grid line 110, and the grid line 110 is used to overlap and connect with the welding strip 120 in a one-to-one correspondence. The current collected by the grid line 110 is derived through the welding strip 120; when the battery cell 100 is located on the carrying area 210, the direction or extension direction of the grid line 110 is defined as the first direction of the carrying area 210, that is, the width direction of the carrying area 210.

[0044] Further, such as Figure 3 , 4 As shown in Figures 5 and 6, the supporting area 210 can be arranged as a plane or a curved surface. When the supporting area 210 is a plane, the battery cell 100 located on the supporting area 210 also remains in a straight state. At this time, the direction or extension direction of the gate line 110 is a straight line arrangement, that is, the first direction is a straight line arrangement; when the supporting area 210 is a curved surface, the battery cell 100 located on the supporting area 210 presents a curved surface corresponding to the supporting area 210. At this time, the direction or extension direction of the gate line 110 is a curved line arrangement, that is, the first direction is a curved line arrangement.

[0045] Furthermore, if Figure 3 As shown, a plurality of carrying areas 210 are provided on the carrier body 200, and the plurality of carrying areas 210 are arranged along a first direction. The arrangement posture of each carrying area 210 is the same, in other words, the length and width of each carrying area 210 are arranged in the same direction, so that when the battery cell 100 is located on the carrying area 210, the gate lines 110 on each battery cell 100 are all along the first direction.

[0046] The limiting component 300, such as Figure 3 , 4 As shown in , 5, the limiting assembly 300 is used to limit the welding strip 120. The limiting assembly 300 is arranged on the carrier body 200, and the limiting assembly 300 is arranged at least on one side of the carrying area 210. In other words, the limiting assembly 300 can be arranged on one side or both sides of the carrying area 210; it is worth noting that the carrying area 210 has a first side 211 and a second side 212, and the first side 211 and the second side 212 are respectively two sides of the carrying area 210 in the first direction.

[0047] In one embodiment, Figure 3 , 45, the limiting component 300 is arranged on the first side 211 or the second side 212 of the carrying area 210, that is, when the battery cell 100 is located in the carrying area 210, the limiting component 300 is located on one side of the battery cell 100 to limit and guide the welding strip 120, so that the welding strip 120 is aligned and overlapped with the grid line 110 on the battery cell 100; in the second embodiment, the limiting component 300 is arranged on the first side 211 and the second side 212 of the carrying area 210, that is, when the battery cell 100 is located in the carrying area 210, the limiting component 300 is located on both sides of the battery cell 100 to limit and guide the welding strip 120 The limiting guide is performed to make the welding strip 120 more aligned and overlapped with the grid line 110 on the battery cell 100; in another embodiment, a plurality of carrying areas 210 are arranged on the carrier body 200, and the carrying areas 210 are arranged along the first direction, wherein the limiting components 300 and the carrying areas 210 are alternately arranged, that is, a limiting component 300 is arranged between every two adjacent carrying areas 210, so that a limiting component 300 is arranged on both sides of each carrying area 210, and each limiting component 300 can limit and guide the welding strip 120 of the battery cell 100 on the carrying areas 210 on both sides.

[0048] Further, such as Figure 6-9 As shown, the limiting component 300 includes a limiting member 310, and the limiting member 310 has at least two limiting parts 311, that is, the limiting part 311 has multiple limiting parts, and the multiple limiting parts 311 are arranged in parallel, so that a limiting area 3112 is formed between two adjacent limiting parts 311, and the limiting area 3112 accommodates the welding strip 120; multiple limiting parts 311 are provided, and a limiting area 3112 is formed between each two adjacent limiting parts 311, and each limiting area 3112 is limited and cooperated with a welding strip 120, so that the welding strip 120 is limited in the limiting area 3112, so as to prevent the welding strip 120 from shifting. In this way, the welding strip 120 is limited by the limiting part 311, and the welding strip 120 will not be offset relative to the grid line 110 of the battery cell 100, which is conducive to maintaining the one-to-one correspondence between the grid line 110 and the welding strip 120.

[0049] Furthermore, if Figure 6 , 7As shown, the limiting portions 311 are located on the first side 211 and / or the second side 212 of the bearing area 210 and are arranged in a directional manner. Specifically, a plurality of limiting portions 311 are arranged in a straight line, and the arrangement direction of the limiting portions 311 is along the second direction. There is an angle between the second direction and the first direction, that is, the second direction is different from the first direction; in one embodiment, the second direction and the first direction are arranged perpendicularly, that is, the limiting portions 311 are arranged along a direction perpendicular to the gate line 110. The spacing between two adjacent limiting areas 3112 is defined as L1; the spacing between two adjacent gate lines 110 on the battery cell 100 is defined as L2; ​​wherein, L1 is equal to or substantially equal to L2, so that the spacing between the welding strips 120 limited by the limited area 3112 is exactly equal to the spacing between the gate lines 110, thereby allowing the welding strips 120 to be aligned one by one with and overlapped with the gate lines 110 on the battery cell 100; preventing the welding strips 120 from shifting in the second direction, thereby improving the accuracy of alignment and overlap between the welding strips 120 and the gate lines 110; it can be understood that the width of the limiting area 3112 is equal to or substantially equal to the width of the welding strip 120, so that the welding strip 120 can just be accommodated in the limiting area 3112.

[0050] like Figure 8 As shown, a plurality of limiting portions 311 form a plurality of limiting areas 3112, and the sum of the lengths of the limiting areas 3112 in the second direction is defined as the limiting section 312. Since the spacing between two adjacent limiting areas 3112 is equal to or substantially equal to the spacing between two adjacent gate lines 110 on the battery cell 100, the welding strip 120 is located in the limiting section 312. The welding strip 120 can be limited correspondingly by the limiting area 3112 formed by the limiting portion 311, that is, each welding strip 120 is located in a limiting area 3112, so that the position of the welding strip 120 and the gate line 110 is limited, thereby preventing the welding strip 120 from being too loose, thereby ensuring that the welding strip 120 and the gate line 110 are aligned and overlapped.

[0051] Specifically, Fig. 9As shown, the limiting portion 311 includes a first portion 3111 and a second portion 3113, the first portion 3111 is used to limit the welding strip 120, and the second portion 3113 is used to guide the welding strip 120. The first portion 3111 is directly or indirectly connected to the carrier body 200, and a limiting area 3112 is formed between two adjacent portions, and the limiting area 3112 is the above-mentioned limiting area 3112 for accommodating the welding strip 120; the second portion 3113 is connected to the first portion 3111, and further, the second portion 3113 is connected to the end of the first portion 3111 away from the carrier body 200, and the second portion 3113 has a guiding surface 3114, and the guiding surface 3114 is arranged obliquely, and a guiding area 3115 is formed between the guiding surfaces 3114 of two adjacent second portions 3113, and the guiding area 3115 is connected to the limiting area 3112, and the guiding area 3115 is used to guide the welding strip 120; wherein, on the same guiding surface 31 A first position and a second position are defined on 14, the distance from the first position to the center of the guide area 3115 is larger than that of the second position, and the distance from the first position to the surface of the carrier body 200 is larger than that of the second position, that is, the guide surface 3114 is arranged obliquely, and the formed guide area 3115 gradually narrows from away from the surface of the carrier body 200 to close to the surface of the carrier body 200, so that the welding strip 120 enters from the guide area 3115, and the welding strip 120 can be directional and fall into the limiting area 3112 along the inclined guide surface 3114; it is worth noting that the center of the guide area 3115 is located on the center line between the two adjacent limiting portions 311, and the two adjacent limiting portions 311 are symmetrical or substantially symmetrical about the center line.

[0052] In one embodiment, Fig.10 , 11 As shown, the limiting member 310 is movable. The limiting member 310 is movably arranged on the side of the carrying area 210. Specifically, the limiting member 310 is arranged in the second direction, and the limiting member 310 has the freedom of movement to slide along the second direction. In other words, the limiting member 310 can move along the second direction on the side of the carrying area 210, that is, when the battery cell 100 is placed on the carrying area 210, the limiting portion 311, the limiting area 3112, and the limiting section 312 of the limiting member 310 can move on the side of the battery cell 100, which is adapted to battery cells 100 of different sizes, so that the limiting assembly 300 has compatibility with battery cells 100 of different sizes.

[0053] As an implementation method, Fig.10As shown, a slot 213 is provided on the carrier body 200. Specifically, the slot 213 is provided on the side of the bearing area 210, and the slot 213 is provided along the second direction. The limiter 310 is embedded in the slot 213, so that the limiter 310 can move in the slot 213 along the second direction to achieve the position movement of the limiter 310. The slot 213 can be provided on the first side 211 and / or the second side 212 of the bearing area 210. Further, as Fig.11 As shown, the position limiting assembly 300 also includes a fixing member 320, which is used to fix the movable position limiting member 310. When the position limiting member 310 is working to limit the welding strip 120, the fixing member 320 fixes the position limiting member 310 to prevent the position limiting member 310 from sliding. When the position limiting member 310 needs to be adjusted, the fixing of the position limiting member 310 can be cancelled by the fixing member 320, so as to achieve the position adjustment of the position limiting member 310. More specifically, the fixing member 320 includes a pressing block 321 and an adjusting portion 322, the pressing block 321 is fixedly connected to the carrier body 200, and the adjusting portion 322 is movably connected to the pressing block 321 and acts on the position limiting member 310, wherein the adjusting portion 322 can be selected as an adjusting screw, which is threadedly connected to the pressing block 321 and contacts the position limiting member 310.

[0054] In another embodiment, the position of the limiting member 310 is fixed. Specifically, the limiting member 310 is fixedly connected to the carrier body 200 or is integrally formed with the carrier body 200 .

[0055] Working principle / steps:

[0056] A limiting member 310 is arranged on the side of the bearing area 210 of the carrier body 200, and the limiting member 310 has a plurality of limiting portions 311, and a limiting area 3112 is formed between adjacent limiting portions 311. When the battery cell 100 is arranged on the bearing area 210, the limiting area 3112 is used to limit the welding strip 120, so that the welding strip 120 can be aligned and overlapped with the grid line 110 on the battery cell 100, thereby preventing the welding strip 120 from being offset relative to the grid line 110 on the battery cell 100; further, limiting members 310 are arranged on both sides of the bearing area, and the welding strip 120 can be limited and guided on both sides of the battery cell 100, thereby further improving the alignment accuracy of the grid line 110 and the welding strip 120 of the battery cell 100; the limiting member 310 is arranged in a movable form, and the position of the limiting member 310 is adjusted to adapt to battery cells 100 of different sizes.

[0057] Technical effect:

[0058] 1. The present application sets a limiting assembly 300 on the carrier body 200 for limiting the position of the welding strip 120. The limiting assembly 300 sets a limiting portion 311 on the side of the bearing area 210, and a limiting area 3112 for accommodating the welding strip 120 is formed between adjacent limiting portions 311. When the welding strip 120 is laid, the welding strip 120 will not be offset by the limiting area 3112, which is conducive to the fixation of the posture of the welding strip 120. The limiting area 3112 provides a clear positioning for the placement of the welding strip 120, so that the welding strip 120 can be accurately aligned to the grid line 110 on the battery cell 100, greatly improving the production efficiency and product quality, and reducing the loss caused by inaccurate alignment. The technical problem of poor quality of the battery cell 100 is solved, and the technical effect of improving the quality of the battery cell 100 is achieved.

[0059] 2. The stopper 310 is slidably disposed on the carrier body 200, and the position of the stopper 310 can be adjusted according to different processes to adapt to different sizes or arrangements of battery cells 100. This design makes the operation more flexible and convenient.

[0060] A guide area 3115 and a limit area 3112 are provided on the limit portion 311, and the welding strip 120 is guided into the limit area 3112 by the guide area 3115. The design of the guide surface 3114 enables the welding strip 120 to enter the limit area 3112 more smoothly, reducing deformation or displacement of the welding strip 120 caused by friction or resistance, thereby ensuring that the welding strip 120 is precisely aligned with the grid line 110 on the battery cell 100. The precise guidance reduces errors caused by human operation, improves the accuracy of welding, and ensures the stability of the relative position between the welding strip 120 and the grid line 110 before welding, laying a good foundation for the subsequent welding process.
