Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic cell string production equipment, and more particularly to a cell string bearing device. BACKGROUND

[0002] With the development of the photovoltaic industry, cell strings need to achieve higher precision and efficiency standards in the production process. The production of cell strings involves multiple processes, including the key step of stacking the solder strip group and the cell sheet according to a specific layout sequence. In this stringing process, the solder strip, as an important conductive component connecting the cell sheet, precise positioning plays a crucial role in ensuring the overall quality of the cell string.

[0003] For example, there is a stringing process route in the industry, which is to place the solder strip first, and then cover the cell sheet onto the solder strip. After placing the solder strip, the solder strip is usually fixed using suction holes. However, the suction effect of the suction hole is small, and the suction fixing effect is poor. When placing the cell sheet, the solder strip is prone to shift and deviate from the predetermined position, resulting in the solder strip not being in the predetermined position on the surface of the cell sheet after solidification, affecting the performance and reliability of the final product. CONTENT OF THE UTILITY MODEL

[0004] To solve the above technical problems, the present application provides a cell string bearing device, which adopts the following technical solutions:

[0009] The driving component is configured to drive the first comb plate and the second comb plate of each shaping component to move in opposite horizontal directions to reduce the width of each gap, and then the solder strip in each gap is shaped to a predetermined position.

[0010] In the process of making a battery string, a prepared welding strip group is first placed on the platform plate, the welding strip group comprising a plurality of welding strips extending along a first horizontal direction, at this time the upper ends of the first comb plate and the second comb plate protrude from the platform plate and form a wide gap; then, the battery sheet is placed on the platform plate, and the battery sheet is first supported by the top ends of the first comb plate and the second comb plate; then, the first comb plate and the second comb plate are lowered, and the first comb plate and the second comb plate are immersed into the platform plate while the welding strip is trimmed to complete the trimming, and the battery sheet and the welding strip accurately trimmed to the predetermined position are stacked.

[0011] The battery string carrying device provided by the application can realize the carrying and trimming of the welding strip through the combination of the platform support, the platform plate, the trimming assembly and the driving assembly. The platform plate is sequentially installed on the platform support along a first horizontal direction, and each platform plate is provided with a plurality of long waist holes extending along a second horizontal direction for accommodating the trimming assembly. This design ensures that the welding strip is stably carried on the platform plate and can be trimmed by the trimming assembly, avoiding the deviation of the welding strip caused by equipment vibration or external factors, and improving the stability and consistency of the production process. The first comb plate and the second comb plate in the trimming assembly are arranged side by side in the long waist hole, and the gap between the comb structures can be adjusted to trim the welding strip. The driving assembly can drive the first comb plate and the second comb plate to move in opposite horizontal directions to reduce the gap width, thereby realizing automatic trimming of the welding strip and improving production efficiency and product quality. By adjusting the gap width and the number of gaps between the comb structures, welding strips of different sizes and quantities can be adapted, so that the same equipment can serve multiple products, improving the flexibility and applicability of the equipment.

[0012] In some embodiments, the battery string carrying device further comprises a plurality of mounting seats corresponding to the platform plates, the mounting seats being located below the platform plates; each platform plate is provided with two long waist holes and two trimming assemblies, and the two trimming assemblies are respectively installed on the mounting seat corresponding to the platform plate, and the mounting seat is in transmission connection with the driving end of the driving assembly.

[0013] The mounting seat is located below the platform plate, and the trimming assembly is installed through the mounting seat to ensure the stability of the trimming assembly. During the operation of the equipment, the mounting seat can effectively reduce the shaking of the trimming assembly, improve the trimming accuracy, and avoid the misalignment of the welding strip caused by unstable components. Each platform plate corresponds to a mounting seat, and this modular design makes maintenance more convenient. When a trimming assembly needs to be repaired or replaced, only the corresponding mounting seat needs to be operated, without affecting the work of other components, improving the reliability of the equipment.

[0014] In some embodiments, the sizing assembly further comprises guide pins, at least two waist holes corresponding in position are formed on each of the first comb plate and the second comb plate, each waist hole extends in the horizontal direction, the number of guide pins is consistent with the number of waist holes on the first comb plate or the second comb plate; each guide pin is fixedly connected with the mounting seat after sequentially passing through the corresponding waist holes on the first comb plate and the second comb plate, so that the first comb plate and the second comb plate can move in the horizontal direction.

[0015] A plurality of waist holes corresponding in position are formed on each of the first comb plate and the second comb plate, and the guide pins sequentially pass through these waist holes and are fixed on the mounting seat. This design ensures that the translational motion of the comb plate in the horizontal direction will not be offset, improving the sizing accuracy. At the same time, the guide pins can provide stable support, making the movement of the comb plate more smooth during the movement process, further improving the reliability of the equipment. By adjusting the position of the guide pins, the movement range of the comb plate can be flexibly adjusted, improving the applicability and flexibility of the equipment.

[0016] In some embodiments, a guide block is installed on each side of the platform plate, the lower end of the guide block is lower than the platform plate, and first and second guide inclined surfaces are formed on the two side surfaces of the lower end of the guide block.

[0017] The sizing assembly further comprises a mounting frame, a first transmission module and a second transmission module, wherein:

[0018] The mounting frame is fixedly installed on the mounting seat, and the two ends of the mounting frame extend upward to form first and second mounting columns;

[0019] The first transmission module comprises a first connecting block, a first roller and a first elastic member, the first connecting block is fixedly connected with the first comb plate, the first roller is rotatably installed on the first connecting block, and the first elastic member is installed on the first mounting column and abuts against the first connecting block; the first elastic member is used to apply an elastic force to the first connecting block to move towards the first guide inclined surface, so that the first roller is pressed against the first guide inclined surface;

[0020] The second transmission module comprises a second connecting block, a second roller and a second elastic member, the second connecting block is fixedly connected with the second comb plate, the second roller is rotatably installed on the second connecting block, and the second elastic member is installed on the second mounting column and abuts against the second connecting block; the second elastic member is used to apply an elastic force to the second connecting block to move towards the second guide inclined surface, so that the second roller is pressed against the second guide inclined surface;

[0021] The driving assembly is arranged below the mounting seat and is configured to drive the mounting seat to vertically ascend and descend, the first roller and the second roller are configured to move along the first guide slope and the second guide slope respectively and approach each other when the mounting seat descends, thereby driving the first comb plate and the second comb plate to move in opposite horizontal directions and reducing the gap width of each gap; and increasing the gap width for the next time of placing the solder strip.

[0022] The driving assembly indirectly controls the horizontal movement of the first comb plate and the second comb plate by controlling the vertical ascent and descent of the mounting seat, thereby simplifying the structure of the equipment. This design reduces the complex transmission device and reduces the manufacturing and maintenance costs. The first guide slope and the second guide slope provide a stable guide path for the rollers, making the movement of the first comb plate and the second comb plate in the horizontal direction more smooth and accurate, improving the straightening effect and quality of the solder strip. When the rollers move along the guide slope, the elastic force of the first elastic member and the second elastic member ensures that the rollers always closely fit the guide slope, improving the stability of the equipment.

[0023] In some embodiments, the first elastic member includes a first spring and a first guide rod extending in the second horizontal direction;

[0024] One end of the first guide rod is fixedly installed on the first mounting column, a first through hole is formed in the first connecting block, and the other end of the first guide rod extends into the first through hole;

[0025] The first spring is sleeved on the first guide rod, and two ends of the first spring abut against the first mounting column and the first connecting block, respectively;

[0026] The second elastic member includes a second spring and a second guide rod extending in the second horizontal direction;

[0027] One end of the second guide rod is fixedly installed on the second mounting column, a second through hole is formed in the second connecting block, and the other end of the second guide rod extends into the second through hole;

[0028] The second spring is sleeved on the second guide rod, and two ends of the second spring abut against the second mounting column and the second connecting block, respectively.

[0029] The combination of the first spring and the first guide rod and the second spring and the second guide rod ensures that the first roller and the second roller can always receive stable thrust when moving along the guide slope, thereby closely fitting the guide slope. This design improves the motion stability and accuracy of the rollers and avoids the deviation of the rollers on the guide slope. The buffering effect of the first elastic member and the second elastic member can ensure that the solder strip receives uniform pressure during the straightening process, thereby improving the straightening effect and quality of the solder strip and providing a good foundation for subsequent processes.

[0030] In some embodiments, the driving assembly comprises a transmission beam extending along the first horizontal direction and a lifting motor;

[0031] Each mounting seat is arranged on the same transmission beam, and the lifting motor is fixedly arranged on the platform support. The lifting motor drives the transmission beam to lift or lower through a synchronous belt wheel structure and / or a lead screw module, so as to drive each mounting seat to lift or lower, and further drive the first comb plate and the second comb plate of each regularizing assembly to move along the opposite horizontal direction.

[0032] The lifting motor drives the transmission beam, which can simultaneously control the lifting of multiple mounting seats, and realizes the centralized control of the regularizing assembly. This design simplifies the operation process, improves the automation level of the equipment, and reduces the production cost. The design of the transmission beam ensures the synchronization of the movement of multiple regularizing assemblies, avoiding the misplacement of the solder ribbon caused by the asynchronous movement. The synchronous belt wheel structure or the lead screw module can provide precise transmission, ensuring that each regularizing assembly remains consistent during the lifting process, improving the production quality. The regularizing assemblies on multiple platform plates can work simultaneously, further improving the production efficiency and shortening the process time. This design is particularly important in mass production, which can significantly improve the production capacity of the production line; at the same time, it also reduces the cost of the driving parts.

[0033] In some embodiments, the battery string carrying device further comprises a ribbon placing assembly and a sheet placing assembly, wherein:

[0034] The ribbon placing assembly is used to place the solder ribbon on each platform plate;

[0035] The sheet placing assembly is used to place the battery sheet on the upper end of the first comb plate and the second comb plate in each regularizing assembly after the ribbon placing assembly places the solder ribbon;

[0036] After the lifting motor drives the transmission beam to lower, the upper end of the first comb plate and the second comb plate in each regularizing assembly sinks into the long waist hole, and the battery sheet is immediately pressed on the regularized solder ribbon.

[0037] The design of the ribbon placing assembly and the sheet placing assembly reduces the manual intervention link, reduces the production cost, and improves the production efficiency. Through the automatic equipment for placing the solder ribbon and positioning the battery sheet, the accuracy and consistency of each process can be ensured. First, the prepared solder ribbon group is placed on the platform plate, the solder ribbon group contains multiple solder ribbons extending along the first horizontal direction, at this time the upper end of the first comb plate and the second comb plate protrudes from the platform plate and forms a wide gap; then, the battery sheet is placed on the platform plate, which will be supported by the top end of the first comb plate and the second comb plate; then, the transmission beam is lowered by the lifting motor, so that the first comb plate and the second comb plate sink into the long waist hole while completing the regularizing of the solder ribbon, and the battery sheet is immediately stacked on the regularized solder ribbon, the whole process is smooth and fast, which improves the automation level of the equipment and ensures the continuity of the process.

[0038] In some embodiments, the middle part of the mounting frame extends upward to form a limiting column located between the first mounting column and the second mounting column.

[0039] A first support rod is installed on the side of the first connecting block facing the limiting column, and the end of the first support rod abuts against the limiting column when the first roller rolls along the first guide slope and lowers to the predetermined position.

[0040] A second support rod is installed on the side of the second connecting block facing the limiting column, and the end of the second support rod abuts against the limiting column when the second roller rolls along the second guide slope and lowers to the predetermined position.

[0041] The design of the limiting column and the support rod provides a clear travel limit for the rollers during the lowering process, avoiding damage to the welding strip caused by excessive movement, such as bending or flattening the welding strip. This design improves the safety of the equipment and ensures the integrity of the welding strip during the sizing process. By adjusting the length of the support rod, different sizes and thicknesses of the welding strip can be accommodated. This design makes the equipment more adaptable and flexible, capable of meeting diverse production needs. This design reduces the deformation or damage of the welding strip caused by improper clamping, improving the yield of the product.

[0042] In some embodiments, the surface of the platform plate is provided with a plurality of suction holes, each suction hole being connected to a negative pressure air source.

[0043] The suction holes connected to the negative pressure air source can effectively adsorb the welding strip, alleviating the movement of the welding strip caused by equipment vibration or external interference. This design ensures the stability and consistency of the welding strip to a certain extent during the sizing process, improving the sizing accuracy. Negative pressure adsorption can accommodate welding strips of different shapes and sizes, enhancing the versatility of the equipment. After the sizing of the welding strip is completed, the suction holes continue to adsorb, ensuring that the welding strip remains in place, reducing the need for secondary adjustment of the welding strip, and improving production efficiency and quality.

[0044] In some embodiments, at least two mounting through holes are formed on the first comb plate, and a corresponding number of rolling wheels are rotatably installed on the first comb plate along the vertical axis, and the circumferential wheel body of the rolling wheel abuts against the second comb plate through the mounting through hole.

[0045] The design of the rolling wheel allows the first comb plate and the second comb plate to move by rolling contact, reducing wear caused by hard friction. This design prolongs the service life of the equipment and reduces maintenance costs. The circumferential wheel body of the rolling wheel abuts against the second comb plate through the mounting through hole, which is a more uniform and smooth contact method, avoiding deformation or damage caused by local high stress.

[0046] Compared with the prior art, the beneficial effects of the technical solution of the present invention are:

[0047] This invention provides a battery string carrying device, in which a straightening component forms several gaps through the comb structure of a first comb plate and a second comb plate. A first transmission module and a second transmission module respectively drive the first and second comb plates to move in opposite horizontal directions to adjust the gap width, thereby straightening the solder strips in each gap to a predetermined position. This design not only improves the straightening efficiency of the solder strips and reduces the time and error of manual adjustment, but also adapts to the straightening requirements of solder strips of different specifications, providing greater flexibility for different production needs.

[0068] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application will be further described in detail below with reference to the drawings and specific embodiments.

[0069] As Figure 1 shown, the battery string bearing device in the embodiment of the present application includes a platform support 1, a platform plate 2, a regularizing assembly 4 and a driving assembly, wherein:

[0070] The platform plate 2 is provided with at least one, and each platform plate 2 is sequentially mounted on the platform support 1 along a first horizontal direction;

[0072] The regularizing assembly 4 includes a first comb plate 41 and a second comb plate 42, and the first comb plate 41 and the second comb plate 42 are arranged side by side in the long waist hole 21, and a plurality of gaps are formed between the comb structures of the upper ends of the first comb plate 41 and the second comb plate 42, and each gap is configured to fall into a solder strip when the platform plate 2 bears the solder strip;

[0073] The driving assembly is at least configured to drive the first comb plate 41 and the second comb plate 42 of each regularizing assembly 4 to move in opposite horizontal directions to reduce the width of each gap, so as to make the solder strip in each gap be regularized to a predetermined position; or, the first comb plate 41 and the second comb plate 42 move in opposite horizontal directions to increase the width of each gap, and prepare to regularize the next batch of solder strips.

[0074] Optionally, the platform support 1 can be made of metal materials such as aluminum alloy or stainless steel, and the height and width of the platform support 1 can be customized according to production needs to adapt to different scales of production lines. The length and width of the long waist hole 21 can be adjusted according to the size and arrangement density of the welding strip to ensure that the regular assembly 4 can adapt to welding strips of different specifications.

[0075] In the process of making a battery string, a prepared welding strip group containing a plurality of welding strips extending in the first horizontal direction is placed on the platform plate 2, and the upper ends of the first comb plate 41 and the second comb plate 42 protrude from the platform plate 2 and form a wider gap at this time; then, the battery sheet is placed on the platform plate 2, and the battery sheet is first supported by the top ends of the first comb plate 41 and the second comb plate 42; then, the first comb plate 41 and the second comb plate 42 are lowered, and the first comb plate 41 and the second comb plate 42 are immersed in the platform plate 2 while completing the regular welding strip, and the battery sheet and the welding strip form a stack.

[0076] The battery string carrying device provided by the application can realize the carrying and regularizing of the welding strip through the combination of the platform support 1, the platform plate 2, the regular assembly 4 and the driving assembly. The platform plate 2 is sequentially installed on the platform support 1 along the first horizontal direction, and each platform plate 2 is provided with a plurality of long waist holes 21 extending along the second horizontal direction for accommodating the regular assembly 4. This design ensures that the welding strip is stably carried on the platform plate 2 while being regularized by the regular assembly 4, avoiding the welding strip from deviating due to equipment vibration or external factors, and improving the stability and consistency of the production process. The first comb plate 41 and the second comb plate 42 in the regular assembly 4 are arranged side by side in the long waist hole 21, and the gap between the comb structures can be adjusted to regularize the welding strip. The driving assembly can drive the first comb plate 41 and the second comb plate 42 to move in opposite horizontal directions, reducing the gap width, thereby realizing automatic regularizing of the welding strip and improving production efficiency and product quality. By adjusting the gap width and the number of gaps between the comb structures, welding strips of different sizes and quantities can be accommodated, so that the same equipment can serve multiple products, improving the flexibility and applicability of the equipment.

[0077] Optionally, as shown in Figures 1-3 The battery string carrying device further comprises a plurality of mounting seats 5 corresponding to the platform plate 2, and the mounting seat 5 is located below the platform plate 2; each platform plate 2 is provided with two long waist holes 21 and two regular assemblies 4, and the two regular assemblies 4 are respectively installed on the mounting seat 5 corresponding to the platform plate 2, and the mounting seat 5 is in transmission connection with the driving end of the driving assembly.

[0078] The mounting seat 5 is located below the platform plate 2, and the regular assembly 4 is installed through the mounting seat 5, which ensures the stability of the regular assembly 4. During the operation of the device, the mounting seat 5 can effectively reduce the shaking of the regular assembly 4, improve the regularity precision, and avoid the misplacement of the solder strip caused by the instability of the assembly. Each platform plate 2 corresponds to one mounting seat 5, and this design makes it more convenient to maintain and replace the regular assembly 4. When a certain regular assembly 4 needs to be repaired or replaced, only the corresponding mounting seat 5 needs to be operated, which does not affect the work of other assemblies, thereby improving the maintainability and reliability of the device.

[0079] Optionally, referring to Figure 2 、 Figure 3 , the regular assembly 4 further comprises guide pins 44, and at least two waist holes 43 corresponding in position are formed in each of the first comb plate 41 and the second comb plate 42, each waist hole 43 extends in the horizontal direction, and the number of the guide pins 44 is consistent with the number of the waist holes 43 on the first comb plate 41 or the second comb plate 42; each guide pin 44 is fixedly connected with the mounting seat 5 after sequentially penetrating through the corresponding waist holes 43 on the first comb plate 41 and the second comb plate 42, so that the first comb plate 41 and the second comb plate 42 can move in the horizontal direction.

[0080] Optionally, the waist hole 43 extends in the horizontal direction and can be oval or rectangular in shape, and the specific shape is designed according to the diameter of the guide pin 44 and the movement range of the comb plate. The length and width of the waist hole 43 need to ensure that each comb plate can move freely in the horizontal direction and cannot produce vertical movement.

[0081] A plurality of waist holes 43 corresponding in position are formed in each of the first comb plate 41 and the second comb plate 42, and the guide pins 44 sequentially penetrate through these waist holes 43 and are fixed on the mounting seat 5. This design ensures that the translational motion of the comb plate in the horizontal direction will not be offset, thereby improving the regularity precision. At the same time, the guide pin 44 can provide stable support, so that the comb plate moves more smoothly during movement, thereby further improving the reliability of the device. By adjusting the position of the guide pin 44, the movement range of the comb plate can be flexibly adjusted, thereby improving the applicability and flexibility of the device.

[0082] Optionally, as shown in Figure 2 、 Figures 4-5 , one guide block 3 is installed on each side of the platform plate 2, and it can be seen that the height of the guide block 3 is fixed. The lower end of the guide block 3 is lower than the platform plate 2, and the lower end of the guide block 3 is formed with a first guide inclined surface 31 and a second guide inclined surface 32 on the two side surfaces thereof;

[0083] The regular assembly 4 further comprises a mounting frame 45, a first transmission module 46 and a second transmission module 47, wherein:

[0084] The mounting frame 45 is fixedly installed on the mounting seat 5, and two ends of the mounting frame 45 extend upward to form a first mounting column 451 and a second mounting column 452;

[0085] The first transmission module 46 includes a first connecting block 461, a first roller 462, and a first elastic member 463. The first connecting block 461 is fixedly connected with the first comb plate 41. The first roller 462 is rotatably installed on the first connecting block 461. The first elastic member 463 is installed on the first mounting column 451 and abuts against the first connecting block 461. The first elastic member 463 is configured to apply an elastic force to the first connecting block 461 to move toward the first guide slope 31, so that the first roller 462 continuously presses against the first guide slope 31.

[0086] The second transmission module 47 includes a second connecting block 471, a second roller 472, and a second elastic member 473. The second connecting block 471 is fixedly connected with the second comb plate 42. The second roller 472 is rotatably installed on the second connecting block 471.

The first roller 462 and the second roller 472 are configured to move along the first guide slope 31 and the second guide slope 32, respectively, and approach each other when the mounting seat 5 descends, so as to drive the first comb plate 41 and the second comb plate 42 to move in opposite horizontal directions and reduce the gap width of each gap.

[0088] The driving assembly indirectly controls the horizontal movement of the first comb plate 41 and the second comb plate 42 by controlling the vertical movement of the mounting seat 5, thereby simplifying the structure of the device. This design reduces complex transmission devices and reduces manufacturing and maintenance costs. The first guide slope 31 and the second guide slope 32 provide a stable guide path for the rollers, making the movement of the first comb plate 41 and the second comb plate 42 in the horizontal direction smoother and more accurate, thereby improving the straightening effect and quality of the solder strip. When the rollers move along the guide slopes, the elastic force of the first elastic member 463 and the second elastic member 473 ensures that the rollers are always tightly attached to the guide slopes, thereby improving the stability of the device.

This design improves the motion stability and accuracy of the roller, and avoids the deviation of the roller on the guide slope. The buffering effect of the first elastic member 463 and the second elastic member 473 can ensure that the welding strip receives uniform pressure during the sizing process, thereby improving the sizing effect and quality of the welding strip and providing a good foundation for subsequent processes.

[0100] Optionally, the first connecting block 461 comprises two fixedly connected parts, namely a first part of the first connecting block 461 and a second part of the first connecting block 461;

[0101] The first connecting block 461 is fixedly connected with the first comb plate 41, and the first roller 462 is rotatably installed on the first part of the first connecting block 461 and abuts against the first guide inclined surface 31 at the lower end of the guide block 3.

[0107] Optionally, the driving assembly includes a transmission beam 6 and a lifting motor, and the transmission beam 6 extends along the first horizontal direction.

[0108] Each mounting seat 5 is arranged on the same transmission beam 6, and the lifting motor is fixedly arranged on the platform support 1. The lifting motor drives the transmission beam 6 to lift through a synchronous belt wheel structure and / or a lead screw module, so as to drive each mounting seat 5 to lift, and then drive the first comb plate 41 and the second comb plate 42 of each regularizing assembly 4 to move along opposite horizontal directions.

[0109] The lifting motor drives the transmission beam 6, which can simultaneously control the lifting of multiple mounting seats 5, realizing centralized control of the regular assembly 4. This design simplifies the operation process, improves the automation level of the equipment, and reduces production costs. The design of the transmission beam 6 ensures the synchronization of the movement of multiple regular assemblies 4, avoiding misalignment of the solder strip caused by asynchronous movement. The synchronous belt wheel structure or lead screw module can provide precise transmission, ensuring that each regular assembly 4 remains consistent during the lifting process, improving production quality. Multiple regular assemblies 4 on the platform plate 2 can work simultaneously, further improving production efficiency and shortening process time. This design is particularly important in mass production, significantly improving the production capacity of the production line.

[0110] Optionally, the battery string carrying device further comprises a strip placing assembly and a sheet placing assembly, wherein:

[0111] The strip placing assembly is used to place the solder strip on each platform plate 2;

[0112] The sheet placing assembly is used to place the battery sheet on the upper end of the first comb plate 41 and the second comb plate 42 in each regular assembly 4 after the strip placing assembly places the solder strip;

[0113] After the lifting motor drives the transmission beam 6 to lower, the upper end of the first comb plate 41 and the second comb plate 42 in each regular assembly 4 sinks into the long waist hole 21, and the battery sheet is then pressed on the regularized solder strip.

[0114] The design of the strip placing assembly and the sheet placing assembly reduces the manual intervention link, reduces production costs, and improves production efficiency. Through the automatic placement of the solder strip and the positioning of the battery sheet, the accuracy and consistency of each process can be ensured. First, place the prepared solder strip group on the platform plate 2, which contains multiple solder strips extending in the first horizontal direction. At this time, the upper end of the first comb plate 41 and the second comb plate 42 protrudes from the platform plate 2 and forms a wide gap; then, place the battery sheet on the platform plate 2, which will be supported by the top end of the first comb plate 41 and the second comb plate 42; then, lower the transmission beam 6 by driving the lifting motor, so that the first comb plate 41 and the second comb plate 42 sink into the long waist hole 21 while completing the regularization of the solder strip, and the battery sheet is then pressed on the regularized solder strip to form a stack. The whole process is smooth and fast, which improves the automation level of the equipment and ensures the continuity of the process.

[0115] Optionally, continuing to refer to Figures 4-5 The middle part of the mounting bracket 45 extends upward to form a limiting column 453, which is located between the first mounting column 451 and the second mounting column 452;

[0116] The first connecting block 461 has a first support rod 7 installed on the side facing the limiting column 453. When the first roller 462 rolls along the first guide slope 31 and lowers to the predetermined position, the end of the first support rod 7 abuts against the limiting column 453.

[0117] The second connecting block 471 has a second support rod 8 installed on the side facing the limiting column 453. When the second roller 472 rolls along the second guide slope 32 and lowers to the predetermined position, the end of the second support rod 8 abuts against the limiting column 453.

[0118] The design of the limiting column 453 and the support rod provides a clear travel limit for the rollers during the lowering process, preventing excessive movement that may damage the welding strip, such as bending or flattening. This design improves the safety of the equipment and ensures the integrity of the welding strip during the sizing process. By adjusting the length of the support rod, it can accommodate welding strips of different sizes and thicknesses. This design makes the equipment more adaptable and flexible, capable of meeting diverse production needs. This design reduces the deformation or damage of the welding strip caused by improper clamping, improving the yield of the product.

[0119] Optionally, referring back to Figure 2 , the surface of the platform plate 2 is provided with a plurality of suction holes 22, each suction hole 22 being connected to a negative pressure source.

[0120] The suction holes 22 are connected to a negative pressure source, which can effectively adsorb the welding strip and alleviate the movement of the welding strip caused by equipment vibration or external interference. This design further ensures the stability and consistency of the welding strip during the sizing process to some extent, improving the sizing accuracy. Negative pressure adsorption can adapt to welding strips of different shapes and sizes, enhancing the versatility of the equipment. After the welding strip is sized, the suction holes 22 continue to adsorb, ensuring that the welding strip remains in place, reducing the need for secondary adjustment of the welding strip, and improving production efficiency and quality.

[0121] Optionally, referring back to Figure 3 , the first comb plate 41 is provided with at least two installation holes 411, and the first comb plate 41 is rotatably installed with rolling wheels 412 corresponding in number to the installation holes 411. The rolling wheels 412 rotate along the vertical axis, and the circumferential wheel body of the rolling wheels 412 abuts against the second comb plate 42 through the installation holes 411.

[0122] The design of the rolling wheels 412 allows the first comb plate 41 and the second comb plate 42 to move by rolling contact, reducing wear caused by hard friction between them. This design prolongs the service life of the equipment and reduces maintenance costs. The circumferential wheel body of the rolling wheels 412 abuts against the second comb plate 42 through the installation holes 411, which is a more uniform and smooth contact method that avoids deformation or damage caused by local high stress.

[0123] The application also provides a battery string production device, which comprises a string grouping mechanism, a welding mechanism, a platform driving mechanism and the aforementioned battery string carrying device, wherein:

[0124] The battery string production device is sequentially provided with a string grouping station and a string connecting station along a second direction, the driving end of the platform driving mechanism is connected to the platform support 1 in the battery string carrying device, and the platform driving mechanism is configured to drive the battery string carrying device to be alternately moved to the string grouping station and the string connecting station, the string grouping mechanism is arranged at the string grouping station, and the welding mechanism is arranged at the string connecting station;

[0125] When the platform driving mechanism drives the battery string carrying device to move to the string grouping station, the string grouping mechanism is configured to lay the welding strip on the battery string carrying device, and the welding strip falls into the corresponding gap, and the string grouping mechanism is further configured to lay a plurality of battery pieces on each platform plate 2 to implement string grouping;

[0126] When the platform driving mechanism drives the battery string carrying device to move to the string connecting station, the welding mechanism implements string connection on the welding strip and the battery pieces after the string grouping on the battery string carrying device.
