Description

Technical Field

[0001] This application relates to the field of photovoltaic cells, and in particular to a cell welding strip processing apparatus and method. Background Technology

[0002] With the development of photovoltaic technology, in order to improve the power conversion efficiency of solar cells, multiple solar cells are welded together by welding strips to form a solar cell string. Therefore, in order to meet the above process requirements, welding equipment for welding solar cells to form solar cell strings has been developed.

[0003] In existing technologies, solar cells are interconnected by welding ribbons. First, welding ribbons need to be welded onto the flat solar cells. Therefore, the welding ribbons need to be placed on the surface of the solar cells and then heated and cured to complete the welding between the welding ribbons and the solar cells. The welding ribbon welding process includes pulling the welding ribbon, cutting the welding ribbon, transferring the welding ribbon, arranging and placing the welding ribbon, and welding the welding ribbon. The welding ribbon itself is flexible and has a small diameter. After the welding ribbon is cut, it is transferred and arranged by a robot. Therefore, the robot that grips the welding ribbon needs to be equipped with multiple gripping structures to grip multiple sets of welding ribbons, resulting in a bulky and complex welding equipment structure and low welding efficiency.

[0004] Therefore, the technical problem with existing technologies is that welding efficiency is low. Summary of the Invention

[0005] This application provides a battery cell welding strip processing apparatus and method, which solves the technical problems of complex welding equipment structure and low welding efficiency, and achieves the technical effect of simplifying the welding equipment structure and improving welding efficiency.

[0006] On the one hand, the battery cell welding strip processing apparatus provided in this application adopts the following technical solution:

[0007] A battery cell welding strip processing apparatus includes: a first carrier for carrying and transferring adhesive components and battery cells; a second carrier disposed below the first carrier, the second carrier including a plurality of movable seats having degrees of freedom of movement along a first direction, the first direction being the arrangement direction of the movable seats; the movable seats having an adsorption function, the plurality of movable seats being used to jointly carry long welding strips, receive adhesive components and battery cells transferred from the first carrier and adsorb and fix them; and a cutting mechanism disposed between any two adjacent initial positions of the movable seats for cutting the welding strip located between the initial positions of two adjacent movable seats.

[0008] Preferably, the first carrier is in the shape of a roller, has a rotational degree of freedom to rotate about an axis, has a rotating circumferential side surface, and has a plurality of operating surfaces on the rotating circumferential side surface, the operating surfaces having an adsorption function.

[0009] Preferably, the first carrier is a triangular, quadrilateral, pentagonal, hexagonal, ..., or N-sided roller.

[0010] Preferably, the top of the movable seat has a bearing surface with adsorption holes for adsorbing welding strips, adhesive parts, and battery cells.

[0011] Preferably, the bearing surface is provided with a groove, the groove is arranged along a first direction, and the depth of the groove is less than the width of the welding strip so that the welding strip is higher than the groove.

[0012] Preferably, the second carrier further includes a guide rail, which is arranged along a first direction and disposed at the bottom of the movable seat, and the movable seat is slidably connected to the guide rail.

[0013] Preferably, the cutting mechanism includes a cutting element disposed between the initial positions of the movable seat, the cutting element having a degree of freedom of movement along a second direction, the second direction being perpendicular or substantially perpendicular to the first direction.

[0014] Preferably, the movable seat is provided with a preheating component, which is disposed on the bearing surface and is used to preheat the viscous component.

[0015] On the other hand, the battery cell welding strip processing method provided in this application adopts the following technical solution:

[0016] A method for processing solar cell welding strips includes: arranging adhesive components on a first carrier; arranging movable seats based on the spacing between the first carrier and arranging the same set of long welding strips on multiple movable seats; driving the first carrier to rotate and move along a first direction, transferring the adhesive components one by one to the movable seats; arranging solar cells on the first carrier; driving the first carrier to rotate and move along the first direction, transferring the solar cells one by one to the movable seats; simultaneously cutting the welding strips between the current movable seat and adjacent movable seats while the solar cells are being transferred; cutting the welding strips between each movable seat; and driving the movable seats after the welding strips have been cut to a heating zone to weld the solar cells and welding strips.

[0017] Preferably, two sets of first carriers are arranged, which are used to carry and transfer the adhesive component and the battery cell, respectively.

[0018] In summary, this application includes at least one of the following beneficial technical effects:

[0019] 1. In this application, battery cells are arranged on a first carrier and welding ribbons are arranged on a second carrier. By rotating and moving the first carrier, adhesive components and battery cells are arranged sequentially on the welding ribbons of the second carrier. During the battery cell arrangement process, the welding ribbon between the current moving seat and the adjacent moving seat can be cut while waiting for one battery cell to be transferred, so that it can enter the heating zone for heating and curing, without having to wait for all battery cells to be transferred before overall transfer and curing. This improves the welding cycle time, solves the technical problems of complex welding equipment structure and low welding efficiency, and achieves the technical effect of simplifying the welding equipment structure and improving welding efficiency.

[0020] 2. The movable seat provided in this application is movable, and the initial position spacing of the movable seat can be adjusted based on the shape of the first carrier, so that the first carrier can rotate and transfer the adhesive component and the battery sheet to the movable seat accurately. The shape of the first carrier can be replaced and the spacing between the movable seats can be adjusted according to different quantity requirements, thereby increasing the scope of application.

[0021] 3. The preheating component on the moving base provides initial heating to the adhesive component, giving it a certain degree of stickiness. This allows for initial fixation of the welding strip, preventing issues such as skewing or slippage, and improving the welding quality of the battery cells.

[0022] 4. A cutting component is set between the initial positions of the moving parts. When the adhesive part is transferred from the first carrier to the moving seat, the cutting component between the current moving seat and the adjacent moving seat can cut the welding strip. Or when the battery cell is transferred from the first carrier to the moving seat, the cutting component between the current moving seat and the adjacent moving seat can cut the welding strip. In this way, the equipment structure is simplified, structural space is saved, and there is no need to set up a separate cutting structure station. At the same time, after cutting, the current moving seat can slide to enter or wait to enter the next process, thus speeding up the overall processing cycle. Attached Figure Description

[0030] This application provides a battery cell welding strip processing apparatus and method, which solves the technical problems of complex welding equipment structure and low welding efficiency, and achieves the technical effect of simplifying the welding equipment structure and improving welding efficiency.

[0031] To better understand the above technical solutions, a detailed description of the technical solutions will be provided below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application.

[0032] To achieve shingled production of 700 solar cells, welding strips 500 need to be welded onto the 700 cells. Therefore, welding equipment for the welding strips 500, or auxiliary equipment to assist in welding the welding strips 500, has emerged. Current mainstream welding strip 500 placement technology involves the following steps: pulling the welding strip 500, cutting the welding strip 500, transferring the welding strip 500, arranging and placing the welding strip 500, and welding the welding strip 500. For example, Ningxia Xiaoniu Automation Equipment Co., Ltd. designed an automatic welding strip 500 placement device and string welding machine. The automatic welding strip 500 placement device includes a welding strip 500 cutting device, a welding strip 500 placement device, a welding table, and a traction table. It utilizes the welding strip 500 placement device that can be perpendicular to the welding strip 500 lines... A grasping and placing mechanism with a translational misalignment action grasps and places the welding strip 500, and a cutting mechanism is used to cut the entire welding strip 500 into multiple segments to achieve accurate arrangement of the welding strip 500 on the grid lines of the battery cell 700; Zhongnengchuang Optoelectronic Technology (Changzhou) Co., Ltd. proposed a multi-busbar series device and a battery string series method for multiple wiring. The multi-busbar series device includes a series worktable and a main grid line wiring mechanism. The main grid line wiring mechanism is used to wire the main grid lines in a first direction. It also includes a movable wiring preparation table, an auxiliary line wiring mechanism and an auxiliary line connection mechanism. The movable wiring preparation table can move along a second direction perpendicular to the first direction under the drive of the drive mechanism. Multiple wiring is achieved by moving the movable wiring preparation table.

[0033] The above equipment and methods are all used for welding the 500 solder strips of the 700 solar cell. The problems with this process are: 1. The wiring mechanism of the 500 solder strips has poor scalability and cannot meet the increasing demand for the number of multi-wire solder strips 500; 2. For the solder strips 500 of multi-gate solar cells 700, the existing solder strip 500 technology requires a corresponding number of solder strip 500 feeding carriers, which not only makes it difficult to replace the solder strips 500, but also occupies a lot of equipment space and is costly.

[0034] Therefore, this application addresses the shortcomings of existing technologies by proposing a patent application that solves the aforementioned problems. The application number is 202211546400.3, and the patent title is "A Simple and Efficient Welding Strip 500 Carrier, Welding Strip 500 Carrier Assembly, Welding Equipment, and Welding Method." This patent relates to the field of photovoltaic technology, and particularly to a welding strip 500 carrier, welding strip 500 carrier assembly, welding equipment, and welding method. The carrier includes: a carrier body for winding the welding strip 500, the carrier body having rotational freedom, and at least one operating surface 111 on the carrier body. The operating surface 111 is planar, and the welding strip 500 is laid across the operating surface 111. The operating surface 111 has several adsorption holes, and the welding strip 500 is adsorbed and fixed by forming a negative pressure within the adsorption holes. This solves the technical problem of complex welding equipment structures in existing technologies, achieving the technical effect of simplifying the structure of welding equipment.

[0035] However, the aforementioned patent, by winding the welding ribbon 500 around the carrier body to bind and tighten the battery cells 700, suffers from several drawbacks. First, because the welding ribbon 500 is supported by metal, the deformation caused by the winding results in poor contact between the welding ribbon 500 and the battery cells 700, easily leading to incomplete welds and reducing the quality and power generation efficiency of the battery cells 700. The applicant, through multiple experiments, has demonstrated that the likelihood of incomplete welds caused by a linear layout of the welding ribbon 500 is significantly lower than that caused by a winding layout. Second, the battery cells 700 bound by the welding ribbon 500 require rotation of a roller for processing. The roller must rotate one full revolution to complete the current workstation's operation. Thus, battery cells 700 on the same roller must wait for the other battery cells 700 to be processed before the roller can proceed to the next process, greatly reducing the processing cycle time and production efficiency.

[0036] Therefore, this application provides another battery cell welding strip processing apparatus and method, which solves the technical problems of complex welding equipment structure and low welding efficiency, and achieves the technical effect of simplifying the welding equipment structure and improving welding efficiency.

[0037] A battery cell welding strip processing device, such as Figure 1 As shown, a welding strip 500 is used to process the battery cell 700, resulting in the surface of the battery cell 700 having the welding strip 500. It includes a first carrier 100, a second carrier 200, and a cutting mechanism 300. The first carrier 100 is used to carry and transfer the adhesive component 600 and the battery cell 700; the second carrier 200 is used to carry the long welding strip 500; and the cutting mechanism 300 is used to cut the welding strip 500.

[0038] First carrier 100, such as Figure 1 As shown, the first carrier 100 is used to carry and transfer the adhesive component 600 and the battery cell 700. The first carrier 100 is arranged in a roller configuration and has a rotational degree of freedom to rotate around an axis, that is, the first carrier 100 can rotate around an axis. The first carrier 100 has a rotating circumferential side surface 110, on which a plurality of operating surfaces 111 are provided. The operating surfaces 111 have an adsorption function and are used to adsorb and fix the adhesive component 600 and the battery cell 700. Specifically, the operating surfaces 111 can be provided with adsorption holes, and a negative pressure is formed in the adsorption holes, so that the adhesive component 600 and the battery cell 700 can be adsorbed and fixed on the operating surfaces 111. It is worth noting that the adsorption function on each operating surface 111 is relatively independent. In other words, the vacuum level of each operating surface 111 can be controlled individually to adsorb or release the adhesive component 600 or the battery cell 700.

[0039] In one embodiment, the first carrier 100 may be a triangular, quadrilateral, pentagonal, hexagonal, ..., or N-sided roller. Correspondingly, three, four, five, six, ..., or N adhesive components 600 or battery cells 700 may be adsorbed and fixed on the first carrier 100. In other words, a ring of adhesive components 600 or battery cells 700 may be adsorbed and fixed on the peripheral side of the first carrier 100. Thus, by controlling the vacuum level on each operating surface 111 and coordinating with the rotation of the first carrier 100 around its axis, the adhesive components 600 or battery cells 700 on the first carrier 100 can be transferred one by one to the second carrier 200.

[0040] It is worth noting that the first carrier 100 can be driven by a motor to rotate around an axis; furthermore, the first carrier 100 also needs to have a degree of freedom of movement in the first direction. In one embodiment, a drive source such as a cylinder, a track, or a linear motor can be provided on the first carrier 100 to enable the first carrier 100 to move in the first direction.

[0041] Furthermore, the first carrier 100 may be provided in two sets, one set for carrying and transferring the adhesive component 600, and the other set for carrying and transferring the battery cell 700, so as to improve the transfer efficiency.

[0042] The second carrier 200, such as Figure 1 , 2 As shown in Figure 3, the second carrier 200 is used to support the long welding ribbon 500. The second carrier 200 is positioned below the first carrier 100, serving to support the welding ribbon 500 and also to receive the adhesive component 600 and the battery cell 700 transferred from the first carrier 100. The long welding ribbon 500 supported by the second carrier 200 refers to a relatively long, uncut welding ribbon 500. There are multiple welding ribbons 500, ranging from 50 to 100. These groups of long welding ribbons 500 are placed on the second carrier 200. After the adhesive component 600 and the battery cell 700 are transferred, they are heated and cured to complete the welding of the welding ribbon 500 onto the battery cell 700. Specifically, the second carrier 200 includes several movable seats 210. These multiple movable seats 210 are arranged along a first direction. It is worth noting that the movable seats 210 have a degree of freedom of movement along the first direction, thus allowing the movable seats 210 to move the battery cell 700 in the first direction.

[0043] Furthermore, such as Figure 1 , 2As shown, each movable seat 210 has a bearing surface 211 on its top surface. The bearing surface 211 is used to bear the welding strip 500, the adhesive part 600 and the battery cell 700. It can be understood that the long welding strip 500 is supported by multiple movable seats 210. That is, the bearing surfaces 211 of multiple movable seats 210 jointly bear the same set of long welding strips 500. The movable seats 210 can only move freely after being cut into short welding strips 500. The bearing surface 211 is provided with adsorption holes. By forming a negative pressure in the adsorption holes, the welding ribbon 500, the adhesive component 600 and the battery cell 700 can be stably adsorbed. It is worth noting that since the adhesive component 600 and the battery cell 700 need to be placed on the welding ribbon 500 in sequence, so that the battery cell 700 is connected to the welding ribbon 500 through the adhesive component 600, in order to ensure that the battery cell 700 is stably adsorbed, the area of ​​the adhesive component 600 can be smaller than the area of ​​the battery cell 700. In this way, the adsorption holes will not be completely covered by the adhesive component 600, and the battery cell 700 can also be adsorbed by the adsorption holes.

[0044] In one embodiment, such as Figure 2 , 3 As shown, a groove 212 is provided on the bearing surface 211. Multiple sets of grooves 212 are provided. The grooves 212 are used to accommodate and fix the welding ribbon 500. In other words, when the welding ribbon 500 is placed on the bearing surface 211, it is also accommodated within the groove 212. Both the welding ribbon 500 and the groove 212 are arranged along a first direction, and the depth of the groove 212 is less than the width of the welding ribbon 500. This ensures that the welding ribbon 500 does not fall entirely into the groove 212; that is, the welding ribbon 500 extends above the groove 212 to contact the adhesive component 600 and the battery cell 700. It is understood that adsorption holes are provided both inside and outside the groove 212.

[0045] The second carrier 200 also includes a guide rail 213, such as Figure 1 , 2 As shown, the guide rail 213 is disposed below the movable seat 210. The guide rail 213 is arranged along the first direction. The movable seat 210 and the guide rail 213 slide together, so that the movable seat 210 can move along the first direction under the action of external drive. In one embodiment, the drive method can be a linear motor or a cylinder.

[0046] In the second carrier 200, each movable seat 210 is movable. Before processing, the initial state of the movable seat 210 needs to be arranged based on the first carrier 100. In the initial state, the long welding strip 500 is arranged on the movable seat 210. Before the welding strip 500 is cut, the movable seats 210 are mutually restrained by the long welding strip 500 and cannot move independently.

[0047] Furthermore, a preheating element is also provided on the bearing surface 211 of each movable seat 210. The preheating element is used to preheat the adhesive component 600, so that the adhesive component 600 initially melts. Even if the adhesive component 600 has a certain degree of stickiness, it can initially fix the welding strip 500, preventing problems such as skewing or slippage of the welding strip 500, and improving the welding quality of the battery cell 700. Specifically, the preheating element adopts an electric heating wire embedded in the bearing surface 211. By energizing the electric heating wire, the bearing surface 211 is heated, thereby preheating the adhesive component 600.

[0048] It is understandable that, such as Figure 3 As shown, in order to prevent the sticky part 600 from sticking to the bearing surface 211 during preheating or heating and curing, an anti-sticking liquid can be sprayed onto the bearing surface 211 before processing; in order to prevent the sticky part 600 from melting and flowing into the adsorption holes on the bearing surface 211, air can also be blown into the adsorption holes to remove the sticky liquid flowing into the adsorption holes.

[0049] Cutting mechanism 300, such as Figure 1 , 2 As shown, the cutting mechanism 300 is used to cut the welding strip 500. Multiple sets of cutting mechanisms 300 are arranged between the initial positions of every two adjacent movable seats 210. Thus, the cutting mechanism 300 can cut the welding strip 500 upwards, causing the welding strip 500 located between the movable seats 210 to break. In this case, the movable seats 210 can move away from their initial positions. In one embodiment, the cutting mechanism 300 includes a cutting element 310, which has a degree of freedom of movement along a second direction, which is perpendicular or substantially perpendicular to the first direction. During its movement along the second direction, the cutting element 310 cuts the upper set of long welding strips 500, causing the welding strip 500 to break. After cutting, the movable seats 210 immediately move to the heating zone 400 for heating and curing. In one embodiment, the cutting element 310 can be driven by a linear motor or a cylinder.

[0050] This application also proposes a method for processing solar cell welding strips, such as... Figure 1 , 4 As shown, based on the above-described apparatus, it includes:

[0051] S1: Adhesive components 600 are arranged on the first carrier 100: the first carrier 100 is driven to rotate, and the adhesive components 600 are sequentially adsorbed on each operating surface 111 by negative pressure.

[0052] S2: Based on the shape and position of the first carrier 100, the spacing between the initial positions of the moving seats 210 is set so that during the rotation and movement of the first carrier 100, the operating surface 111 of the first carrier 100 and the bearing surface 211 of the second carrier 200 correspond to each other, so that the adhesive 600 (or battery sheet 700) falls accurately onto the bearing surface 211.

[0053] S3: Arrange the same set of long welding strips 500 on the bearing surface 211 of multiple movable seats 210, and fix the welding strips 500 by adsorption through the adsorption holes on the bearing surface 211.

[0054] S4: Drive the first carrier 100 to rotate and move along the first direction, transferring the adhesive parts 600 one by one to the movable seat 210;

[0055] S5: Battery cells 700 are arranged on the first carrier 100; drive the first carrier 100 to rotate, and the battery cells 700 are sequentially adsorbed on each operating surface 111 by negative pressure.

[0056] S6: Drive the first carrier 100 to rotate and move along the first direction, transferring the battery cells 700 one by one to the movable seat 210;

[0057] S7: While transferring the battery cell 700 or the adhesive part 600, the solder strip 500 between the current moving seat 210 and the adjacent moving seat 210 is cut.

[0058] S8: Cut the welding strip 500 between each movable seat 210;

[0059] S9: Drive the movable seat 210, after the welding strip 500 has been cut, to the heating zone 400 to weld the battery cell 700 to the welding strip 500.

[0060] It is worth noting that, in order to improve cycle efficiency, when the first carrier 100 transfers the adhesive 600 to the current moving seat 210, the cutting part 310 between the current moving seat 210 and the adjacent moving seat 210 responds and cuts the corresponding upper welding strip 500. After the first carrier 100 transfers the battery cell 700 to the moving seat 210, the moving seat 210 can slide into the next process without waiting for all the battery cells 700 to be transferred.

[0061] Furthermore, it can also be configured such that after the first carrier 100 transfers the adhesive 600 to the current moving seat 210, and after the first carrier 100 transfers the battery cell 700 to the moving seat 210, the cutting component 310 between the current moving seat 210 and the adjacent moving seat 210 responds, and the cutting component 310 cuts off the corresponding upper welding strip 500, so that the moving seat 210 can slide into the next process without waiting for all the battery cells 700 to be transferred.

[0062] In one embodiment, the first carrier 100 may be arranged in two groups, one group of first carrier 100 for carrying and transferring the adhesive component 600, and the other group of first carrier 100 for carrying and transferring the battery cell 700.

[0063] Working principle / steps:

[0064] Adhesive components 600 are arranged on the first carrier 100; movable seats 210 are arranged based on the spacing of the first carrier 100, and the same set of long welding strips 500 are arranged on multiple movable seats 210; the first carrier 100 is driven to rotate and move along the first direction, transferring the adhesive components 600 one by one to the movable seats 210; battery cells 700 are arranged on the first carrier 100; the first carrier 100 is driven to rotate and move along the first direction, transferring the battery cells 700 one by one to the movable seats 210; while the battery cells 700 or adhesive components 600 are transferred, the welding strips 500 between the current movable seat 210 and the adjacent movable seat 210 are cut; the welding strips 500 between the movable seats 210 are cut one by one; the movable seats 210 after the welding strips 500 are cut are driven to move to the heating zone 400 to weld the battery cells 700 and the welding strips 500.

[0065] Technical effects:

[0066] 1. In this application, battery cells 700 are arranged on a first carrier 100 and welding ribbons 500 are arranged on a second carrier 200. By rotating and moving the first carrier 100, adhesive parts 600 and battery cells 700 are arranged sequentially on the welding ribbons 500 of the second carrier 200. During the arrangement of battery cells 700, the welding ribbons 500 between the current moving seat 210 and the adjacent moving seat 210 can be cut while waiting for one battery cell 700 to be transferred. Then, the battery cells 700 can enter the heating zone 400 for heating and curing. This eliminates the need to wait for all battery cells 700 to be transferred before the overall transfer and curing, thereby improving the welding cycle time and solving the technical problems of complex welding equipment structure and low welding efficiency. This achieves the technical effect of simplifying the welding equipment structure and improving welding efficiency.

[0067] 2. The movable seat 210 provided in this application is movable, and the initial position spacing of the movable seat 210 can be adjusted based on the shape of the first carrier 100, so that the first carrier 100 can rotate and transfer the adhesive 600 and the battery sheet 700 to the movable seat 210 accurately. Based on different quantity requirements, the shape of the first carrier 100 can be replaced and the spacing between the movable seats 210 can be adjusted to increase the scope of application.

[0068] 3. The preheating component on the movable seat 210 preheats the adhesive component 600, giving it a certain degree of stickiness. This allows for the initial fixation of the welding strip 500, preventing problems such as skewing or slippage of the welding strip 500 and improving the welding quality of the battery cell 700.

[0069] 4. A cutting element 310 is set between the initial positions of the moving parts. When the adhesive part 600 is transferred from the first carrier 100 to the moving seat 210, the cutting element 310 between the current moving seat 210 and the adjacent moving seat 210 can cut the welding strip 500. Or when the battery cell 700 is transferred from the first carrier 100 to the moving seat 210, the cutting element 310 between the current moving seat 210 and the adjacent moving seat 210 can cut the welding strip 500. In this way, the equipment structure is simplified, structural space is saved, and there is no need to set up a separate cutting structure station.
