Description

Technical Field

[0001] This application relates to the field of photovoltaic product processing equipment technology, and more specifically, to an apparatus and method for pre-preparing a combiner module. Background Technology

[0002] In the manufacturing process of photovoltaic modules, connecting solar cells into strings using solder ribbons is a crucial step. For back-contact (BC) cells, whose electrodes are all located on the back of the cell, series connection between cells is achieved using solder ribbons. In a conventional BC cell string structure, cells located in the middle of the string typically only need to be connected to adjacent cells before and after them using long solder ribbons; however, cells located at the beginning and end of the string, in addition to being connected to adjacent middle cells using long solder ribbons, also need to be connected to busbars for current collection using short solder ribbons to enable conduction between the string and external circuitry.

[0003] Currently, the typical process flow for manufacturing such BC battery strings in the industry is usually a step-by-step sequential operation: First, long solder strips are cut to a predetermined length and welded (or bonded with conductive adhesive) to the corresponding back electrodes of the middle and first and last battery cells to complete the interconnection between the battery cells; then, short solder strips are cut separately and welded to specific positions on the first and last battery cells; finally, after the above steps are completed, the busbars are transported to a designated station and aligned and welded with the short solder strips already fixed on the battery cells to form a complete battery string circuit path.

[0004] However, the existing process has significant shortcomings: First, the process involves numerous steps, including multiple independent feeding, positioning, and welding operations for long and short solder strips and busbars, resulting in a long production cycle and limiting overall production efficiency. Second, the welding between the short solder strips and busbars needs to be performed on the battery cells, where the operating space is limited and the positioning accuracy requirements are extremely high, increasing the process difficulty and the risk of alignment deviations, which may affect welding quality and reliability. Third, the multi-step operation also means more equipment stations and more complex mechanical structures, increasing equipment costs and maintenance difficulty.

[0005] Therefore, optimizing the BC battery string, especially the connection process between its first and last battery cells and busbars, simplifying the process, improving production efficiency and welding quality, has become a technical problem that urgently needs to be solved in this field.

[0033] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0034] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0035] 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 discussed further in subsequent figures.

[0036] Reference Figures 1a-2 As shown, according to one embodiment of this application, a device for pre-fabrication of a busbar component is provided. The device includes a support mechanism 1, which includes a feeding component 11, a platform 12, a pressure needle assembly 13, and a cutting assembly 14. The feeding component 11 is configured to provide solder strips. The platform 12 is disposed on one side of the loading component 11 along a first direction; the platform 12 is capable of supporting the busbar and the welding strip led out from the loading component 11; the pressure pin assembly 13 can be installed on the platform 12, or the pressure pin assembly 13 can be an independent component outside the platform, and the pressure pin assembly 13 is used to press the welding strip. The cutting component 14 can be installed on the platform 12, or the cutting component 14 can be a component independent of the platform, and the cutting component 14 is disposed between the pressure needle component 13 and the feeding component 11; the cutting component 14 is used to cut the welding strip led out from the feeding component 11; The equipment also includes a welding mechanism 2, which is used to weld the busbar and the welding strip.

[0037] The equipment for pre-fabrication of busbar components provided in this application embodiment can be applied to the production process of BC battery strings. Before welding short solder strips to the first and last cells of the battery string, the short solder strips are pre-welded to the busbars to form a busbar component, so that the busbar component can be transported to the first and last cells of the battery string in the next process.

[0038] Specifically, the equipment for prefabricating the busbar assembly includes a support mechanism 1 and a welding mechanism 2. The support mechanism 1 serves as a platform for carrying, positioning, and cutting short welding strips, and also as a platform for carrying the busbar. The welding mechanism 2 is used to weld and fix the short welding strips on the support mechanism 1 to the busbar.

[0039] More specifically, in the carrying mechanism 1, the welding strip roll is wound onto the feeding component 11. For example, the feeding component 11 may include multiple feeding guide rollers to guide the welding strip feeding. That is, the feeding component 11 is a welding strip unwinding device used to provide continuous welding strip rolls, and its output end is set towards the platform 12, which can continuously lead out the welding strip 011 and transport it to the surface of the platform 12.

[0040] The platform 12 is positioned beside the feeder 11 along a first direction, which is the conveying direction of the welding strip. The welding strip extends along the first direction and is supported on the platform 12 after being drawn out from the feed guide roller of the feeder 11. A pressure needle assembly 13 and a cutting assembly 14 are mounted on the platform 12. Specifically, the pressure needle assembly 13 can press the welding strip, and is used to press the welding strip after it has been conveyed to the correct position to prevent displacement of the welding strip during cutting or welding. The cutting assembly 14 is positioned between the pressure needle assembly 13 and the feeder 11, and is used to cut the welding strip drawn out from the feeder 11, cutting it to a preset length to form a short welding strip.

[0041] The device for pre-fabrication of the current collector assembly provided in this application embodiment achieves precise feeding, positioning, and cutting of the welding strip 011 through the carrying mechanism 1 to form a short welding strip of a preset length. The carrying mechanism 1 also simultaneously positions and places the current collector strip 012. Then, the welding mechanism 2 completes the welding of the short welding strip and the current collector strip to form an integrated current collector assembly 01. Then, the current collector assembly is transported as a whole to the first and last battery cells of the battery string in the next process and welded to the first and last battery cells. This avoids welding the short welding strip and the current collector strip on the battery cells, which helps to improve the welding quality and reduce the process difficulty. It can also save process steps, thereby shortening the production cycle and improving production efficiency.

[0042] Reference Figures 1c-1eAs shown, in one embodiment, the pressure needle assembly 13 includes a pressure needle body 131, a first driving member 132, and a second driving member 133. The first driving member 132 and the second driving member 133 are both connected to the pressure needle body 131. The first driving member 132 can drive the pressure needle body 131 to move along a second direction, and the second driving member 133 can drive the pressure needle body 131 to move downward to press the solder strip, or to move upward to release the solder strip.

[0043] In this specific example, the pressure pin assembly 13 includes a pressure pin body 131, a first driving member 132, and a second driving member 133. The first driving member 132 drives the pressure pin body 131 to move along a second direction, which forms a predetermined angle with the first direction, for example, a 90° angle. Before the solder strip is drawn from the feeder 11 and placed in position on the stage 12, the pressure pin body 131 moves along the second direction under the driving action of the first driving member 132 to move away from the placement path of the solder strip, thereby avoiding interference with the normal laying of the solder strip. After the solder strip is placed in position, the pressure pin body 131 first moves along the second direction under the driving action of the first driving member 132 to approach and align with the solder strip. Then, the pressure pin body 131 moves downward under the driving action of the second driving member 133 to press the solder strip, preventing the solder strip from warping or shifting during the welding process and improving the stability and consistency of the welding.

[0044] After the pre-fabrication of the busbar assembly is completed, the pressure pin body 131 first moves upward under the driving action of the second driving member 133 to release the solder strip, and then moves along the second direction under the driving action of the first driving member 132 to move away from the solder strip, so as to facilitate the unloading of the busbar assembly after welding.

[0045] Optionally, both the first drive component 132 and the second drive component 133 are cylinders. (Refer to...) Figure 1b , Figure 1c As shown, the first direction is the X direction, and the second direction is the Y direction.

[0046] Reference Figures 1c-1e As shown, in one embodiment, at least two pressure needle bodies 131 are provided, and the at least two pressure needle bodies 131 are arranged at intervals along the second direction; The pressure needle assembly 13 further includes a first mounting plate 134, at least two pressure needle bodies 131 are disposed on the first mounting plate 134, and the first driving member 132 and the second driving member 133 are both connected to the first mounting plate 134.

[0047] In this specific example, since a busbar is welded to multiple parallel-spaced solder strips in the busbar assembly, the stage 12 carries multiple parallel-spaced solder strips, and a pressure needle body 131 is provided for each solder strip. The multiple pressure needle bodies 131 are arranged at intervals along a second direction and are all mounted on a first mounting plate 134. The first drive member 132 and the second drive member 133 are both connected to the first mounting plate 134. For example, the second drive member 133 is located at the drive end of the first drive member 132, and the first mounting plate 134 is located at the drive end of the second drive member 133; or, the first drive member 132 is located at the drive end of the second drive member 133, and the first mounting plate 134 is located at the drive end of the first drive member 132.

[0048] By setting the first mounting plate 134, multiple pressure needle bodies 131 are integrated and installed, enabling the first driving component 132 and the second driving component 133 to synchronously drive all pressure needle bodies 131 to move, ensuring the consistency of movement of multiple pressure needle bodies 131, thereby achieving synchronous pressing of multiple welding strips and improving the processing efficiency of the equipment; at the same time, the multiple pressure needle bodies 131 are arranged at intervals along the second direction, which can accurately press multiple parallel welding strips, avoiding the problem of uneven force on the welding strip caused by the excessive pressing range of a single pressure needle body 131.

[0049] Reference Figures 1c-1e As shown, in one embodiment, the pressure needle assembly 13 further includes a first adapter plate 135 and a guide plate 136. The guide plate 136 is fixedly disposed, the first mounting plate 134 is horizontally slidably connected to the first adapter plate 135, and the first adapter plate 135 is vertically slidably connected to the guide plate 136. The driving end of the first driving component 132 is connected to the first mounting plate 134, and the driving end of the second driving component 133 is connected to the first adapter plate 135.

[0050] In this specific example, the pressure needle assembly 13 also includes a first adapter plate 135 and a guide plate 136. The guide plate 136 is a fixed component that can be bolted to a preset position on the platform 12, maintaining its fixed installation posture. The first mounting plate 134 and the first adapter plate 135 are horizontally slidably connected. Specifically, a slide rail extending in a second direction is provided on the first adapter plate 135, and a matching slider is provided at the bottom of the first mounting plate 134. The slider is embedded in the slide rail, allowing the first mounting plate 134 to slide relative to the first adapter plate 135 in the second direction. The first adapter plate 135 and the guide plate 136 are vertically slidably connected. Specifically, a vertical slide rail is provided on the guide plate 136, and a matching slider is provided on the side of the first adapter plate 135. The slider is embedded in the vertical slide rail, allowing the first adapter plate 135 to slide relative to the guide plate 136 in the vertical direction.

[0051] Furthermore, the driving end of the first driving member 132 is directly connected to the first mounting plate 134, and its driving force is used to drive the first mounting plate 134 and thereby drive the pressure needle body 131 to slide along the second direction; the driving end of the second driving member 133 is directly connected to the first adapter plate 135, and its driving force is used to drive the first adapter plate 135 and thereby drive the first mounting plate 134 and the pressure needle body 131 to slide along the vertical direction.

[0052] During equipment operation, when the welding strip is led out from the feeding component 11 and laid on the platform 12, the first driving component 132 drives the first mounting plate 134 to move along the second direction, thereby causing the pressure needle body 131 to move away from the laying path of the welding strip and achieve avoidance. After the welding strip is laid in place, the first driving component 132 first drives the first mounting plate 134 and then drives the pressure needle body 131 to move along the second direction to approach and align with the welding strip. Then, the second driving component 133 drives the first adapter plate 135 to descend in the vertical direction, causing the first mounting plate 134 and the pressure needle body 131 to descend synchronously. The pressure needle body 131 presses against the surface of the welding strip, achieving a tight fit between the welding strip and the busbar.

[0053] In this embodiment, by setting a first adapter plate 135 and a guide plate 136, the horizontal (second direction) and vertical movements of the pressure needle body 131 are separated and guided. The horizontal movement is guided by the sliding pair between the first mounting plate 134 and the first adapter plate 135, and the vertical movement is guided by the sliding pair between the first adapter plate 135 and the guide plate 136. This avoids interference between the two directions of movement, greatly improves the movement accuracy and positioning accuracy of the pressure needle body 131, and ensures that the pressure needle body 131 can be accurately pressed into the preset position of the welding strip.

[0054] Furthermore, the fixed configuration of the guide plate 136 provides a stable support foundation for the pressure needle assembly 13. Compared to the direct drive structure, the sliding pair connection method reduces swaying and deflection during movement, making the pressure of the pressure needle body 131 more uniform when pressing the welding strip, and avoiding deformation or displacement of the welding strip due to uneven pressure. Moreover, the driving objects of the first drive member 132 and the second drive member 133 are clearly separated. The horizontal avoidance action and the vertical pressing action can be independently controlled and precisely coordinated. This enables effective avoidance during welding strip laying and rapid response during pressing, improving the working cycle of the pressure needle assembly 13 and adapting to the high-efficiency production requirements of automated production lines.

[0055] Reference Figure 1b , Figure 1c , Figure 1f As shown, in one embodiment, the cutting assembly 14 includes a first cutter 141, a second cutter 142, a third drive member 143 and a fourth drive member 144, wherein the first cutter 141 is disposed on the platform 12 and is used to support the welding strip. The second cutter 142 is disposed above the first cutter 141. The third drive member 143 and the fourth drive member 144 are both connected to the second cutter 142. The third drive member 143 can drive the second cutter 142 to move along the second direction. The fourth drive member 144 can drive the second cutter 142 to move downward to cut the solder strip, or to move upward to release the solder strip.

[0056] In this specific example, the cutting assembly 14 includes a first cutter 141, a second cutter 142, a third drive member 143, and a fourth drive member 144. The first cutter 141 supports the welding strip and can be fixedly mounted on the platform 12; alternatively, it can be configured to move vertically. The third drive member 143 drives the second cutter 142 to move along a second direction. Before the welding strip is drawn from the loading member 11 and placed on the platform 12, the second cutter 142 moves along the second direction under the drive of the third drive member 143 to move away from the welding strip's placement path, thus avoiding interference with the normal laying of the welding strip. After the welding strip is placed, the second cutter 142 first moves along the second direction under the drive of the third drive member 143 to approach and align with the welding strip. Then, the second cutter 142 moves downward under the drive of the fourth drive member 144 to cooperate with the first cutter 141 in achieving precise cutting of the welding strip, ensuring the consistency of the length of the resulting short welding strips.

[0057] After the pre-fabrication of the combiner assembly is completed, the second cutter 142 first moves upward under the driving action of the fourth drive member 144 to release the solder strip, and then moves along the second direction under the driving action of the third drive member 143 to move away from the solder strip, so as to facilitate the unloading of the combiner assembly after welding.

[0058] Optionally, both the third drive component 143 and the fourth drive component 144 are cylinders.

[0059] Reference Figure 1a , Figure 1c , Figure 1f As shown, in one embodiment, the number of the second cutter 142 is at least two, and the at least two second cutters 142 are arranged at intervals along the second direction; The cutting assembly 14 further includes a second mounting plate 145, at least two second cutters 142 are disposed on the second mounting plate 145, and the third drive member 143 and the fourth drive member 144 are both connected to the second mounting plate 145.

[0060] In this specific example, a first cutter 141 and a second cutter 142 are provided for each solder strip; multiple second cutters 142 are arranged at intervals along a second direction and are all mounted on a second mounting plate 145; a third drive member 143 and a fourth drive member 144 are both connected to the second mounting plate 145. For example, the fourth drive member 144 is disposed at the drive end of the third drive member 143, and the first mounting plate 134 is disposed at the drive end of the fourth drive member 144; or, the third drive member 143 is disposed at the drive end of the fourth drive member 144, and the first mounting plate 134 is disposed at the drive end of the third drive member 143.

[0061] By setting the second mounting plate 145, multiple second cutters 142 are integrated and installed, enabling the third drive component 143 and the fourth drive component 144 to synchronously drive all the second cutters 142, ensuring the consistency of movement of multiple second cutters 142, thereby achieving synchronous cutting of multiple solder strips, greatly improving the preparation efficiency of short solder strips, and adapting to the needs of parallel processing of multiple solder strips in BC battery strings; at the same time, the one-to-one correspondence between the first cutter 141 and the second cutter 142 ensures the precise cutting position of each solder strip, avoiding the problem of some solder strips being cut too long or too short, and improving the dimensional consistency of short solder strips.

[0062] Reference Figure 1f As shown, in one embodiment, the cutting assembly 14 further includes a second adapter plate 146, the driving end of the third driving member 143 is connected to the second adapter plate 146, the fourth driving member 144 is mounted on the second adapter plate 146, and the driving end of the fourth driving member 144 is connected to the second mounting plate 145; and the second mounting plate 145 is vertically slidably connected to the second adapter plate 146.

[0063] In this specific example, the cutting assembly 14 also includes a second adapter plate 146, wherein the driving end of the third driving member 143 is directly connected to the second adapter plate 146, and the fourth driving member 144 is installed in a preset mounting position on the second adapter plate 146, and its driving end is directly connected to the second mounting plate 145.

[0064] The second mounting plate 145 and the second adapter plate 146 are vertically slidably connected. Specifically, a vertical slide rail can be provided on the second adapter plate 146, and a matching slider can be provided on the side of the second mounting plate 145. The slider is embedded in the vertical slide rail, so that the second mounting plate 145 can slide relative to the second adapter plate 146 in the vertical direction.

[0065] During equipment operation, the welding strip is drawn out from the feeding component 11 and passes above the first cutter 141. The third drive component 143 drives the second adapter plate 146 to move along the second direction, thereby driving the second mounting plate 145 and the second cutter 142 to move synchronously away from the conveying path of the welding strip, thus avoiding it. After the welding strip is pulled to a preset length by the clamping component 15, the third drive component 143 drives the second adapter plate 146 to reset, and the second cutter 142 moves to directly above the first cutter 141. Subsequently, the fourth drive component 144 drives the second mounting plate 145 to descend vertically, thereby driving the second cutter 142 to descend and cooperate with the first cutter 141 to cut the welding strip.

[0066] In this embodiment, by setting a second adapter plate 146, the horizontal avoidance action controlled by the third drive member 143 and the vertical cutting action controlled by the fourth drive member 144 are structurally separated. The horizontal avoidance movement will not affect the vertical cutting stroke, ensuring that the descent path of the second cutter 142 is consistent each time it cuts, improving the consistency of the welding strip cutting length, and avoiding cutter offset or cutting size deviation caused by motion interference.

[0067] Furthermore, the fourth drive component 144 is integrated and mounted on the second adapter plate 146, making the overall structure of the cutting assembly 14 more compact and reducing the space occupied on the platform 12, thus meeting the requirements of miniaturized equipment design. At the same time, the integrated structure reduces the length of pipelines and lowers the difficulty of equipment maintenance. In addition, the structural design of the vertical sliding pair makes the downward stroke of the second cutter 142 adjustable. By adjusting the drive stroke of the fourth drive component 144, it can adapt to the cutting requirements of welding strips of different thicknesses, improving the versatility of the cutting assembly 14 and meeting diverse production needs without replacing the cutter.

[0068] Optionally, the first cutter 141 can be configured as a separate structure, that is, multiple first cutters 141 are provided and each first cutter 141 is corresponding to a second cutter 142; or, the first cutter 141 can also be configured as an integral structure, that is, a larger first cutter 141 is provided and all the second cutters 142 are corresponding to it.

[0069] Furthermore, the first cutter 141 is mounted on the fourth mounting plate 147. Optionally, the fourth mounting plate 147 can be connected to the second adapter plate 146. Thus, while the third driving member 143 drives the second adapter plate 146, thereby causing the second mounting plate 145 and the second cutter 142 to move along the second direction, the second adapter plate 146 also drives the fourth mounting plate 147 and the first cutter 141 to move synchronously along the second direction.

[0070] Reference Figure 1cAs shown, in one embodiment, the stage 12 is provided with a guide groove 121 for positioning the welding strip at a position corresponding to the first cutter 141.

[0071] In this specific example, the guide groove 121 extends along the first direction, and its width is slightly larger than the width of the welding strip. After the welding strip is drawn out from the loading part 11, it is embedded in the guide groove 121 and extends along the guide groove 121 to the busbar placement area of ​​the carrier 12. The position of the guide groove 121 corresponds to the position of the first cutter 141. The welding strip is supported by the first cutter 141 in the guide groove 121. The guide groove 121 can guide and position the welding strip, ensuring that the welding strip always maintains the preset position during the conveying and cutting process, avoiding the problem of inaccurate cutting position caused by the welding strip deviating. At the same time, the guide groove 121 can limit the swing of the welding strip, making the contact between the welding strip and the first cutter 141 more stable, improving the stability of the cutting process, and reducing the risk of burrs after the welding strip is cut.

[0072] Reference Figure 1c As shown, in one embodiment, the platform 12 has a material-taking groove 123 at a position corresponding to the guide groove 121. The depth of the material-taking groove 123 is greater than the depth of the guide groove 121, the width of the material-taking groove 123 is greater than the width of the guide groove 121, and the length of the material-taking groove 123 is less than the length of the guide groove 121.

[0073] In this specific example, the stage 12 has a material-taking groove 123 at a position corresponding to the guide groove 121. The guide groove 121 guides and positions the welding strip, ensuring positional accuracy during welding strip transport and cutting. The width of the material-taking groove 123 is greater than the width of the guide groove 121, the length is less than the length of the guide groove 121, and the depth is greater than the depth of the guide groove 121. In specific implementation, the material-taking groove 123 can be located in the middle section of the guide groove 121, and the length direction of the material-taking groove 123 extends along the first direction, with both ends not exceeding the length range of the guide groove 121, ensuring that the guiding function of the guide groove 121 for the welding strip is not affected.

[0074] The material picking groove 123 is adapted to the subsequent busbar component handling equipment. After the busbar component is welded on the platform 12, the welding strip gripping component of the handling equipment can extend into the material picking groove 123 to support the welding strip from below, thereby achieving stable gripping of the busbar component.

[0075] The material-grabbing groove 123 facilitates precise gripping by the handling equipment. The width of the groove 123 is greater than the width of the guide groove 121, providing sufficient space for the gripping component of the handling equipment to reach the area beneath the welding strip. The length of the groove 123 is less than the length of the guide groove 121, ensuring that the guide groove 121 can still effectively position both ends of the welding strip, preventing the welding strip from shifting before gripping. This solves the problem of difficulty in gripping and easy damage to the welding strip caused by the structural limitations of traditional platforms. The depth of the groove 123 is greater than the depth of the guide groove 121, ensuring sufficient clearance between the welding strip and the bottom of the groove 123, allowing the gripping component of the handling equipment to extend into the groove 123 and reach the area beneath the welding strip.

[0076] The design of the material-grabbing groove 123 allows the prefabrication equipment for the combiner module to be structurally compatible with subsequent handling equipment, eliminating the need for additional lifting or pushing mechanisms on the platform 12 and simplifying the equipment structure. The handling equipment can directly grab the combiner module from the material-grabbing groove 123, shortening the material-grabbing stroke, improving the efficiency of process connections, and adapting to the continuous operation requirements of automated production lines. Furthermore, the depth of the material-grabbing groove 123 is greater than the depth of the guide groove 121, allowing the gripping components of the handling equipment to smoothly lift the welding strip from below, rather than squeezing or clamping it from above. This avoids deformation or surface damage to the welding strip during the gripping process, ensuring the quality of the combiner module and providing a good foundation for subsequent welding processes with battery cells.

[0077] Reference Figure 1a As shown, in one embodiment, the device further includes a clamping assembly 15, which is mounted on the stage 12 and is movable in a first direction. The clamping assembly 15 is used to clamp the end of the welding strip that is away from the feeder 11.

[0078] In this specific example, the clamping assembly 15 can be a pneumatic or electric clamping assembly, connected to a linear drive mechanism on the platform 12 to achieve movement along the first direction. During the feeding of the welding strip, the clamping assembly 15 first moves along the first direction toward the feeding component 11 to clamp the free end of the welding strip, and then moves along the first direction away from the feeding component 11 to smoothly pull the welding strip out of the feeding component 11 and stretch it to a preset length before laying it flat on the platform 12. By setting the clamping assembly 15, which can move along the first direction, the automatic feeding and tensioning of the welding strip is realized, replacing the manual pulling operation of the welding strip and improving the automation level of the equipment; at the same time, the pulling action of the clamping assembly 15 can ensure the consistency of the welding strip feeding length, avoid the deviation in the laying position caused by the loosening of the welding strip, and provide stable preconditions for subsequent pressing and welding processes.

[0079] Optionally, refer to Figure 5a As shown, the clamping assembly 15 can stretch the solder ribbon 011 to a first preset length, so that the solder ribbon 011 is located only on one side of the busbar 012. This busbar assembly 01 is suitable for connecting to the edge cells of the battery string. The clamping assembly 15 can also stretch the solder ribbon 011 to a second preset length, so that the solder ribbon 011 extends to both sides of the busbar 012. This busbar assembly 01 is suitable for connecting two adjacent battery strings. It is understood that the second preset length is greater than the first preset length.

[0080] Reference Figure 1a , Figure 1b , Figure 1e As shown, in one embodiment, the device further includes a support assembly 16, which is mounted on the platform 12 and located on the side of the pressure needle assembly 13 away from the cutting assembly 14; the support assembly 16 is used to support the manifold.

[0081] In this specific example, the support component 16 is positioned below the busbar placement area of ​​the platform 12. When the busbar is placed on the platform 12, the support component 16 supports the busbar from below, keeping it horizontal. When the solder ribbon is laid on top of the busbar, the support component 16, in conjunction with the pressure pin component 13, ensures a tight fit between the solder ribbon and the busbar. The support component 16 provides stable support for the busbar, preventing it from bending or deforming due to its own weight or external disturbances, and ensuring a uniform contact area between the busbar and the solder ribbon. Simultaneously, the support component 16, located outside the pressure pin component 13, supports the end of the solder ribbon, further enhancing the bonding effect between the solder ribbon and the busbar.

[0082] Reference Figure 1a , Figure 1c , Figure 1e As shown, in one embodiment, the support assembly 16 includes a support drive 160 and a support block 161, the first end of the support block 161 being used to support the busbar, and the second end of the support block 161 being connected to the support drive 160. The support drive 160 drives the support block 161 to move upward to move closer to the busbar, or the support drive 160 drives the support block 161 to move downward to move away from the busbar.

[0083] In this specific example, the support drive 160 can be, for example, a cylinder; it drives the support block 161 to rise and fall vertically. After the welding strip and busbar are laid, the support drive 160 drives the support block 161 to rise and lift the busbar, making the busbar in close contact with the welding strip; after welding, the support drive 160 drives the support block 161 to fall and release the busbar assembly for easy subsequent handling. The rising and falling movement of the support block 161 can flexibly adjust the height of the busbar, lifting it up before welding to ensure full contact with the welding strip and guaranteeing reliable contact before welding; after welding, it falls down to avoid the support block 161 interfering with the unloading of the busbar assembly, improving the smoothness of the equipment's process connections.

[0084] Reference Figure 1a , Figure 1c , Figure 1e As shown, in one embodiment, multiple support blocks 161 are spaced apart along a second direction, and the support assembly 16 further includes a third mounting plate 162, with the multiple support blocks 161 mounted on the third mounting plate 162, and the support drive member 160 connected to the third mounting plate 162.

[0085] In this specific example, multiple support blocks 161 are evenly spaced along the length direction (i.e., the second direction) of the third mounting plate 162; the support drive component 160 is connected to the third mounting plate 162, driving the third mounting plate 162 to synchronously raise and lower all support blocks 161. By integrating multiple support blocks 161 into the third mounting plate 162, synchronous raising and lowering of the multiple support blocks 161 is achieved, ensuring that the lifting height of each part of the busbar is consistent and preventing the busbar from tilting due to uneven force; at the same time, the multiple support blocks 161 are spaced along the second direction, which can accurately support multiple points of the busbar, further improving the uniformity of the adhesion between the busbar and the welding strip.

[0086] Reference Figure 1b As shown, in one embodiment, the support assembly 16 further includes an elastic element 163, and the second end of the support block 161 is connected to the support drive element 160 through the elastic element 163.

[0087] In this specific example, the elastic element 163 can be a spring. When the supporting drive 160 drives the supporting block 161 to rise and lift the busbar, the elastic element 163 is in a compressed state. Through its own elastic deformation, the elastic element 163 keeps the clamping force of the supporting block 161 on the busbar flexible. The setting of the elastic element 163 realizes the flexible support of the supporting block 161 on the busbar, avoiding deformation of the busbar or welding strip caused by rigid clamping. At the same time, the elastic force of the elastic element 163 can adaptively adjust the lifting height of the supporting block 161, so that each welding strip can fully contact the busbar, ensuring the reliability of the contact before welding and improving the welding quality.

[0088] Reference Figure 1g As shown, in one embodiment, the first end of the support block 161 includes a protrusion 1611 and a recess 1612, the protrusion 1611 and the recess 1612 being alternately arranged.

[0089] In this specific example, the first end surface of the support block 161 is machined with an alternating concave and convex structure. When the support block 161 supports the busbar, only the protrusion 1611 contacts the lower surface of the busbar, creating localized pressure at the intersection of the weld strip and the busbar. The alternating arrangement of the protrusion 1611 and the recess 1612 changes the support method of the support block 161 on the busbar from surface contact to point contact, creating localized pressure concentration at the intersection of the weld strip and the busbar, thus improving the tightness of the fit between the weld strip and the busbar. Because the intersection area of ​​the weld strip and the busbar is small, localized contact is more likely to increase welding strength than surface contact. At the same time, the localized contact method can reduce heat loss during the welding process, making the welding energy more concentrated in the connection area between the weld strip and the busbar, effectively improving the welding strength and solving the problem of insufficient welding strength caused by surface contact.

[0090] Reference Figure 1c As shown, in one embodiment, the platform 12 is provided with a vacuum suction hole 120 near the support block 161, the vacuum suction hole 120 being used to suction and fix the busbar.

[0091] In this specific example, the vacuum suction port 120 is connected to an external vacuum generator. When the manifold is placed on the stage 12, the vacuum generator is activated, and the vacuum suction port 120 generates negative pressure to adsorb and fix the manifold onto the surface of the stage 12. After welding is completed, the vacuum generator stops working, and the vacuum suction port 120 releases the manifold. The vacuum suction port 120 is designed to fix the manifold, preventing it from shifting and ensuring the accuracy of the welding position.

[0092] In addition, refer to Figure 1c As shown, a slot 122 can also be provided on the platform 12 to engage the busbar for auxiliary positioning.

[0093] Furthermore, the platform 12 is connected to the lifting mechanism 17, which can drive the platform 12 to move up and down as a whole to cooperate with the welding mechanism 2 to complete the welding operation.

[0094] Reference Figure 3 As shown, in one embodiment, the device further includes a feeding mechanism 3 for providing a busbar; The feeding mechanism 3 includes a feeding component 31, a clamping component 32 and a cutting component 33, wherein the cutting component 33 is disposed between the feeding component 31 and the clamping component 32; One end of the busbar extends from the feeder 31 and is clamped and fixed by the clamping member 32. The cutting member 33 is used to cut the busbar.

[0095] In this specific example, the busbar is wound onto the feeder 31 before entering the stage 12. The feeder 31 may include, for example, multiple guide wheels. The clamping member 32 may be a pneumatic gripper, which clamps the free end of the busbar to keep it taut. The cutting member 33 may be a cutting blade assembly, which cuts the busbar after it has been stretched to a preset length to obtain a busbar of the required length.

[0096] The feeding mechanism 3 enables automatic feeding and fixed-length cutting of the busbars, replacing manual cutting and improving the automation level of the equipment. At the same time, the tensioning effect of the clamping member 32 ensures that the cutting length of the busbars is consistent, avoiding dimensional deviations caused by busbar slack, and providing busbars with uniform specifications for subsequent welding strip welding.

[0097] Reference Figure 4 As shown, in one embodiment, the device further includes a conveying mechanism 4 having a vacuum nozzle 41 for attracting the manifold, and the conveying mechanism 4 is configured to convey the manifold from the feeding mechanism 3 to the platform 12.

[0098] In this specific example, the conveying mechanism 4 may be a multi-axis robotic arm, and the vacuum nozzle 41 is mounted on the end effector of the conveying mechanism 4. After the feeding mechanism 3 completes the cutting of the manifold, the conveying mechanism 4 drives the vacuum nozzle 41 to move above the cut manifold, the vacuum nozzle 41 generates negative pressure to adsorb the manifold, and then the manifold is transported to the preset position of the platform 12.

[0099] The conveying mechanism 4 enables the automatic transport of the busbar from the feeding mechanism 3 to the carrier 12, connecting the busbar cutting and welding process, and greatly improving the automation level of the equipment. At the same time, the vacuum nozzle 41 can smoothly grasp the busbar, avoiding deformation or damage to the busbar during the transport process, and ensuring the quality of the busbar.

[0100] According to another embodiment of this application, a method for pre-fabrication of a busbar component is provided, the method comprising: S101, control the feeding component 11 to provide welding strip, lead out the welding strip and convey it to the carrier; S102, control the pressure pin assembly 13 to press the welding strip, and then control the cutting assembly 14 to cut the welding strip to obtain a short welding strip of a predetermined length; S103. Place the busbar on the platform and pre-fit the busbar and short solder strip on the platform; S104. The welding mechanism 2 controls the welding of the busbar and the short welding strip to obtain the busbar assembly.

[0101] In the method for pre-preparing a busbar assembly provided in this application embodiment, in step S101, the welding strip is continuously released by the loading component 11 and pulled to the platform 12. The platform 12 provides a stable bearing base for the welding strip, ensuring the accurate conveying path of the welding strip and preparing for subsequent cutting and bonding. Specifically, the welding strip can be pulled by the clamping component 15.

[0102] In step S102, the welding strip conveyed to the stage 12 is first pressed by the pressure needle assembly 13 to fix the position of the welding strip and prevent it from shifting during cutting; then the cutting assembly 14 is controlled to cut the welding strip to accurately obtain a short welding strip of a predetermined length that meets production requirements. The pressing action precedes the cutting action, which is the key to ensuring the dimensional accuracy of the short welding strip.

[0103] In step S103, the busbar is placed on the platform 12. The platform 12 is used to support and position the busbar so that it is precisely aligned and initially bonded to the prepared short welding strip, providing a stable bonding foundation for subsequent welding and avoiding misalignment during welding. Specifically, the busbar is supplied by the feeding mechanism 3 and transported from the feeding mechanism 3 to the platform 12 by the transport mechanism 4.

[0104] In step S104, the welding mechanism 2 (such as a laser welding machine, ultrasonic welding machine, etc.) is controlled to weld the pre-bonded busbar and the short welding strip, so that the two form an integrated busbar assembly 01, completing the pre-preparation process.

[0105] The method for pre-fabrication of the busbar assembly provided in this application embodiment can obtain an integrated busbar assembly 01. Then, the busbar assembly as a whole is transferred to the first and last battery cells of the battery string in the next process and welded to the first and last battery cells. This avoids welding the short solder strips and busbars on the battery cells, which helps to improve the welding quality and reduce the process difficulty. It can also save process steps, thereby shortening the production cycle and improving production efficiency.

Those skilled in the art should understand that modifications can be made to the above embodiments without departing from the scope and spirit of this application.
