Description

Technical Field

[0001] This application belongs to the field of battery manufacturing technology, specifically relating to a welding strip arrangement device and a battery production line. Background Technology

[0002] In the XBC battery module string welding process, the traditional battery string is prepared with the battery string. A battery string has nearly a hundred or so solder strips. However, a battery module is usually made up of 12 battery strings. The method of laying out the solder strips one by one results in low solder strip laying efficiency.

[0003] In existing technologies, multiple solder strips are laid on the battery module at one time using a solder strip laying mechanism. However, since the positions and polarities of two adjacent solder strips on the battery module are usually different, the initial cutting and distance adjustment of the solder strips are quite complicated, resulting in the overall laying efficiency of the solder strips still being unsatisfactory.

[0004] Therefore, there is an urgent need for equipment that can improve the efficiency of welding strip laying. Utility Model Content

[0029] The following is combined with Figures 1-12 This application describes a ribbon laying apparatus and a battery production line according to embodiments thereof.

[0030] like Figures 1 to 12 As shown, according to a first aspect of this application, a welding strip arrangement device is provided, including: a conveying mechanism 500, a first module 100, a second module 200, a third module 300, and a fourth module 400; the first module 100 and the third module 300 are sequentially arranged on a first side of the conveying mechanism 500 along the conveying direction (refer to the X direction in the figure); the second module 200 and the fourth module 400 are sequentially arranged on a second side of the conveying mechanism 500 along the conveying direction, and the second module 200 is arranged opposite to the first module 100, and the fourth module 400 is arranged opposite to the third module 300.

[0031] Specifically, in this embodiment, the provided conveying mechanism 500 can be used to convey and support the battery component 600. Since the existing battery component 600 typically has two battery packs 62, two workstations (i.e., a first workstation and a second workstation) can be provided on the conveying mechanism 500. The first module 100, the second module 200, the third module 300, and the fourth module 400 are respectively disposed on opposite sides of the conveying mechanism 500 along the conveying direction. The second module 200 is disposed opposite to the first module 100 on opposite sides of the first workstation, and the fourth module is disposed opposite to the third module on opposite sides of the second workstation, so that when performing... Figure 1 and Figure 2 When laying the solder ribbons on the battery component 600 provided in this application, the first solder ribbon group and the second solder ribbon group can be placed on two different battery packs 62 of the battery component 600 at the first station by the first module 100 and the second module 200, respectively. The third solder ribbon group and the fourth solder ribbon group can be placed on two battery packs 62 of the battery component 600 at the second station by the third module 300 and the fourth module 400, respectively. This improves the efficiency of solder ribbon laying in terms of the number of battery components 600. The conveying mechanism 500 can move the battery component 600, so that the solder ribbon laying equipment provided in this application can directly complete the whole-plate laying of solder ribbons on the two battery packs of the battery component 600 in one go, further improving the whole-plate laying efficiency of solder ribbons on the battery component 600.

[0032] Optionally, the first module 100 is used to arrange the first welding strip group at a first set position of the conveying mechanism 500, the second module 200 is used to arrange the second welding strip group at a second set position of the conveying mechanism 500, the third module 300 is used to arrange the third welding strip group at a third set position of the conveying mechanism 500, and the fourth module 400 is used to arrange the fourth welding strip group at a fourth set position of the conveying mechanism 500; the first welding strip group includes multiple first welding strips, the second welding strip group includes multiple second welding strips, the third welding strip group includes multiple third welding strips, and the fourth welding strip group includes multiple fourth welding strips, and the polarity of the first welding strip 63 is opposite to that of the third welding strip, and the polarity of the second welding strip 64 is opposite to that of the fourth welding strip.

[0033] In practical applications, the battery component 600 typically includes a glass plate 61 and multiple battery cells 622 spliced ​​and arranged on the glass plate 61, and multiple solder strips are usually required on the back of the multiple battery cells 622. For example... Figure 1 As shown, the battery component 600 consists of 12 battery strings 621 and a glass plate 61, arranged in 2 columns and 6 rows, as follows. Figure 2As shown, each battery string 621 consists of 12 half-cells and 20 rows of solder ribbons, with 6 solder ribbons in odd-numbered rows and 5 solder ribbons in even-numbered rows (the number of half-cells and solder ribbon rows, as well as the number of solder ribbons in each row, can be adjusted for other battery component 600 battery string 621). The first solder ribbon group and the second solder ribbon group are positioned one half-cell apart.

[0034] In this embodiment, the first module 100 and the second module 200 can stack the first and second solder ribbon groups onto the first and second predetermined positions of the conveying mechanism 500 according to a predetermined method. When the conveying mechanism 500 is equipped with a battery component 600, the first and second solder ribbon groups are stacked onto the first and second predetermined positions of the battery component 600, respectively. The first predetermined position is usually set on one of the battery packs 62 on the battery component 600, and the second predetermined position is usually set on the other battery pack on the battery component 600. The number of first solder ribbons 63 and the number of second solder ribbons 64 that the first and second solder ribbon groups can include can be adjusted according to the specific pattern of the battery component 600. The polarity of the first and second solder ribbons is usually the same, but in some embodiments, they can be different. By placing multiple first solder ribbons 63 and multiple second solder ribbons 64 on the two battery packs 62 of the battery component 600 each time, the first module 100 and the second module 200 improve the laying efficiency of the solder ribbons compared to the method of placing the solder ribbons one by one in the prior art.

[0035] Similarly, the third module 300 and the fourth module 400 can stack the third and fourth ribbon groups onto the third and fourth designated positions of the conveying mechanism 500 according to a set method. When the conveying mechanism 500 is equipped with a battery component 600, the third and fourth ribbon groups are stacked onto the third and fourth designated positions of the battery component 600, respectively. The third designated position is usually set on one of the battery groups 62 on the battery component 600, and the fourth designated position is usually set on the other battery group 62 on the battery component 600. The number of third solder ribbons 63 and fourth solder ribbons 64 that the third and fourth solder ribbon groups may include can be adjusted according to the specific design of the battery component 600. The polarities of the third and fourth solder ribbons are usually the same, but in some embodiments, they may be different. The third module 100 and the fourth module 200 place multiple third solder ribbons 63 and multiple fourth solder ribbons 64 on the two battery groups 62 of the battery component 600 each time, which improves the laying efficiency of the solder ribbons compared to the method of placing the solder ribbons one by one in the prior art.

[0036] This application improves the efficiency of the entire sheet of solder ribbons on the battery component 600 by arranging the first and second solder ribbon groups that need to be placed on the battery component 600 through the first module 100 and the second module 200, respectively, and arranging the third and fourth solder ribbon groups through the third module and the fourth module, respectively.

[0037] In the above structure, the first module 100, the second module 200, the third module 300, and the fourth module 400 typically each include at least one set of adjustment mechanism, slitting mechanism, and pick-and-place mechanism. The separate arrangement of the first, second, third, and fourth solder strip groups enables the slitting mechanism to cut multiple first solder strips 63, second solder strips 64, third solder strips, or fourth solder strips of the same length at one time when slitting the solder strips. It also enables the pick-and-place mechanism to clamp multiple first solder strips 63 from the slitting mechanism at one time and place them directly to the first set position of the battery component 600 simultaneously, or to clamp multiple second solder strips 64 from the slitting mechanism at one time and place them directly to the second set position of the battery component 600 simultaneously. This simplifies the adjustment process of the spacing or position between the solder strips and further improves the overall solder strip arrangement efficiency of the battery component 600.

[0038] After the welding ribbon of the battery component 600 is arranged on the whole plate by the welding ribbon arrangement equipment provided in this application, subsequent welding ribbon and other processes can be carried out to meet the series or parallel connection between the battery cells 622 in the battery component 600.

[0039] Optionally, such as Figures 3 to 5 As shown, the welding strip arrangement equipment also includes a third module 300 and a fourth module 400. The conveying mechanism 500 is also provided with a second station. The third module 300 and the fourth module 400 are respectively arranged on opposite sides of the second station. The third module 300 enables the third welding strip group to be arranged at the third set position of the second station, and the fourth module 400 enables the fourth welding strip group to be arranged at the fourth set position of the second station. The third welding strip group includes multiple third welding strips, and the fourth welding strip group includes multiple fourth welding strips. The third welding strips and the fourth welding strips are arranged alternately and at intervals at the third set position and the fourth set position.

[0040] Optionally, such as Figures 3 to 6 As shown, the conveying mechanism 500 is provided with a first station and a second station, which are arranged sequentially along the conveying direction; the first module 100 and the second module 200 are arranged opposite each other on opposite sides of the first station; the third module 300 and the fourth module 400 are arranged opposite each other on opposite sides of the second station.

[0041] Specifically, in this embodiment, the first and second workstations are arranged along the conveying direction, so that the conveying mechanism 500 can transport the battery component 600 to the first and second workstations in sequence. After the first module 100 and the second module 200 have laid out the first and second welding strip groups of the battery component 600 at the first workstation, it is convenient for the third module 300 and the fourth module 400 to continue laying out the third and fourth welding strip groups of the battery component 600 that have moved to the second workstation. This improves the rationality of the position setting of each module, simplifies the structure of each mechanism, further improves the welding strip laying efficiency, and reduces the space ratio and equipment cost of the equipment.

[0042] In the above embodiments, the first module 100 and the second module 200 are arranged opposite to each other, and the third module 300 and the fourth module 400 are arranged opposite to each other. This facilitates the placement of the first and second solder ribbon groups on the two different battery packs 62 of the battery component 600, and the placement of the third and fourth solder ribbon groups on the two different battery packs 62 of the battery component 600. At the same time, it can avoid interference between the first module 100 and the second module 200, and between the third module 300 and the fourth module 400, thereby improving the reliability and operating efficiency of the equipment.

[0043] Optionally, such as Figure 4 As shown, the first module 100 and the fourth module 400 have the same structure, and the second module 200 and the third module 300 have the same structure.

[0044] Specifically, in practical applications, multiple electrode rows are typically spaced apart on the spliced ​​battery cells 622, with each solder strip stacked on a different electrode row. When the first solder strip 63 and the third solder strip 64 are alternately stacked on one of them (for example...), Figure 1 When multiple electrode rows on the battery pack 62 (one row on the right side) are applied, the first solder strip 63 and the third solder strip 64 have opposite polarities. Simultaneously, the second and fourth solder strips are alternately stacked on another (e.g., on the right side). Figure 1 When multiple electrode rows are applied to the battery pack 62 (one row on the left), the second and fourth solder strips have opposite polarities, while the first solder strip usually has the same polarity as the second solder strip 64, and the third and fourth solder strips have the same polarity. In this embodiment, the structures of the first module 100 and the fourth module 400, as well as the structures of the second module 200 and the third module 300, are usually designed to be the same, simplifying the structure of the entire solder strip arrangement equipment without affecting the operation of the entire equipment.

[0045] Optionally, such as Figures 3 to 5As shown, the first module 100 includes a first welding strip unwinding mechanism 11, a first welding strip buffering mechanism 12, a first welding strip pressing mechanism 13, a first welding strip pulling mechanism 14, a first welding strip slitting mechanism 15, and a first welding strip picking and placing mechanism 16; wherein, the first welding strip unwinding mechanism 11, the first welding strip buffering mechanism 12, the first welding strip pressing mechanism 13, and the first welding strip pulling mechanism 14 are arranged sequentially so that the first welding strip slitting mechanism 15 can slit out the first welding strip group, and the first welding strip picking and placing mechanism 16 is used to place the first welding strip group to a first set position.

[0046] The second module 200 includes a second welding strip unwinding mechanism 21, a second welding strip buffering mechanism 22, a second welding strip pressing mechanism 23, a second welding strip pulling mechanism 24, a second welding strip slitting mechanism 25, and a second welding strip picking and placing mechanism 26; wherein, the second welding strip unwinding mechanism 21, the second welding strip buffering mechanism 22, the second welding strip pressing mechanism 23, and the second welding strip pulling mechanism 24 are arranged sequentially so that the second welding strip slitting mechanism 25 can cut out a second welding strip group, and the second welding strip picking and placing mechanism 26 is used to place the second welding strip group to a second set position.

[0047] Specifically, in this embodiment, the first unwinding mechanism 11 in the first module 100 is used to unwind multiple welding strips. The number of unwound welding strips depends on the specific design of the battery component 600, for example... Figure 1 In the battery component 600, the first welding strip unwinding mechanism 11 can unwind 20 welding strips. These 20 unwound welding strips pass through the first welding strip buffer mechanism 12 and then enter the first welding strip pressing mechanism 13. The first welding strip pulling mechanism 14 clamps the 20 welding strips and moves them a specific distance. The first welding strip pressing mechanism 13 then presses the welding strips, allowing the first welding strip slitting mechanism 15 to cut the 20 welding strips, forming a first welding strip group. The first welding strip picking and placing mechanism 16 then picks up or sucks up the cut first welding strip group, moves it above the battery component 600, and places it at a first predetermined position on the battery component 600. The first welding strip slitting mechanism 15 can also adjust the spacing between the welding strips after slitting the first welding strip group to meet the placement requirements of the first welding strip group.

[0048] In the above structure, the first welding strip pressing mechanism 13 can be equipped with multiple guide grooves to ensure the accurate positioning of the 20 welding strips; the specific distance that the first welding strip pulling mechanism 14 moves is the total length of the first welding strip group; after the first welding strip slitting mechanism 15 has slitted the welding strips, it can also adjust the distance between each welding strip so that it can match the spacing of the electrode rows on the battery component 600. In addition, the first welding strip unwinding mechanism 11, the first welding strip buffering mechanism 12, the first welding strip pressing mechanism 13 and the first welding strip pulling mechanism 14 are arranged in sequence, which facilitates the first welding strip pulling mechanism 14 to pull the welding strip and improves the reliability of the first module 100.

[0049] Furthermore, the arrangement and operation of the mechanisms in the second module 200 are similar to those in the first module 100, and will not be repeated here. It should be noted that the positions of the first welding strip picking and placing mechanism 16 and the second welding strip picking and placing mechanism 26 at the first station can be staggered to avoid interference when placing the first welding strip group and the second welding strip group, thereby improving the reliability of the entire equipment.

[0050] Optionally, such as Figures 3 to 5 As shown, the third module 300 includes a third welding strip unwinding mechanism 31, a third welding strip buffering mechanism 32, a third welding strip pressing mechanism 33, a third welding strip pulling mechanism 34, a third welding strip slitting mechanism 35, and a third welding strip picking and placing mechanism 36; wherein, the third welding strip unwinding mechanism 31, the third welding strip buffering mechanism 32, the third welding strip pressing mechanism 33, and the third welding strip pulling mechanism 34 are arranged sequentially so that the third welding strip slitting mechanism 35 can cut out the third welding strip group, and the third welding strip picking and placing mechanism 36 is used to place the third welding strip group to the third set position.

[0051] The fourth module 400 includes a fourth welding strip unwinding mechanism 41, a fourth welding strip buffering mechanism 42, a fourth welding strip pressing mechanism 43, a fourth welding strip pulling mechanism 44, a fourth welding strip slitting mechanism 45, and a fourth welding strip pick-and-place mechanism 46; wherein the fourth welding strip unwinding mechanism 41, the fourth welding strip buffering mechanism 42, the fourth welding strip pressing mechanism 43, and the fourth welding strip pulling mechanism 44 are arranged sequentially so that the fourth welding strip slitting mechanism 45 can slit out the fourth welding strip group, and the fourth welding strip pick-and-place mechanism 46 is used to place the fourth welding strip group to the fourth set position.

[0052] Specifically, in this embodiment, the operating modes and positions of the third module 300 and the fourth module 400 are similar to those of the first module 100 and the second module 200, and will not be described again. It should be noted that, in order to ensure that the first, second, third, and fourth solder strip groups are accurately placed in their respective positions on the battery component 600, the positions of each mechanism in each module can be customized according to actual needs, referring to... Figure 4 .

[0053] Optionally, such as Figures 3 to 5 As shown, the first welding strip unwinding mechanism 11, the first welding strip buffering mechanism 12, the first welding strip pressing mechanism 13, the first welding strip pulling mechanism 14, the third welding strip unwinding mechanism 31, the third welding strip buffering mechanism 32, the third welding strip pressing mechanism 33, and the third welding strip pulling mechanism 34 are arranged sequentially along the conveying direction; the fourth welding strip unwinding mechanism 41, the fourth welding strip buffering mechanism 42, the fourth welding strip pressing mechanism 43, the fourth welding strip pulling mechanism 44, the second welding strip unwinding mechanism 21, the second welding strip buffering mechanism 22, the second welding strip pressing mechanism 23, and the second welding strip pulling mechanism 24 are arranged sequentially in the opposite direction of the conveying direction.

[0054] Specifically, in this embodiment, based on Figure 1 The provided battery component 600 template allows the mechanisms of each module to be arranged in the aforementioned positions, enabling the first welding strip pulling mechanism 14 and the third welding strip pulling mechanism 34 to smoothly pull multiple welding strips from the first welding strip unwinding mechanism 11 and the third welding strip unwinding mechanism 31, respectively. Meanwhile, the second welding strip pulling mechanism 24 and the fourth welding strip pulling mechanism 44 can smoothly pull multiple welding strips from the second welding strip unwinding mechanism 21 and the fourth welding strip unwinding mechanism 41, respectively. At the same time, each welding strip picking and placing mechanism can place the corresponding welding strip group in the corresponding position of the battery component 600, thereby realizing the placement of the entire welding strip of the battery component 600.

[0055] Optionally, such as Figure 7 As shown, the first welding strip pressing mechanism 13, the second welding strip pressing mechanism 23, the third welding strip pressing mechanism 33 and the fourth welding strip pressing mechanism 43 respectively include a first pressing member 131, a second pressing member 132 and a pressing drive member 133; the first pressing member 131 or the second pressing member 132 is provided with a plurality of guide grooves 1321 arranged side by side, and the guide grooves 1321 are used to place the welding strip; the pressing drive member 133 is connected to the first pressing member 131 and is used to move the first pressing member 131 closer to or away from the second pressing member 132.

[0056] Specifically, in this embodiment, the first welding strip pressing mechanism 13, the second welding strip pressing mechanism 23, the third welding strip pressing mechanism 33, and the fourth welding strip pressing mechanism 43 can be designed with the same structure. When pressing the welding strip, each welding strip pressing mechanism can drive the first pressing member 131 to move closer to the second pressing member 132 through the pressing drive member 133 to press the welding strip in the guide groove 1321, which facilitates the subsequent cutting of the corresponding welding strip by each welding strip cutting mechanism.

[0057] After the welding strip is cut, the clamping drive 133 can loosen the welding strip by driving the first clamping member 131 away from the second clamping member 132, or by driving the second clamping member 132 away from the first clamping member 131, so that the welding strip can be easily picked up by each welding strip picking and placing mechanism. When each welding strip group extends along the first direction, each guide groove 1321 also extends accordingly along the first direction. The clamping drive 133 can be a cylinder or a motor, and its connection with the first clamping member 131 can also be achieved through a transmission component; there are no further restrictions.

[0058] Optionally, such as Figure 8As shown, the first welding strip pulling mechanism 14, the second welding strip pulling mechanism 24, the third welding strip pulling mechanism 34 and the fourth welding strip pulling mechanism 44 each include a guide rail 141 and a clamp assembly 142 movably disposed on the guide rail 141; the clamp assembly 142 includes a plurality of clamps 1421 arranged side by side, the clamps 1421 are used to clamp the welding strip, and the clamp assembly 142 can move closer to or away from the corresponding welding strip pressing mechanism along the guide rail 141.

[0059] Specifically, in this embodiment, the first welding strip pulling mechanism 14, the second welding strip pulling mechanism 24, the third welding strip pulling mechanism 34, and the fourth welding strip pulling mechanism 44 can be designed with the same structure. The clamping assembly 142 of each welding strip pulling mechanism can clamp multiple welding strips into the corresponding welding strip pressing mechanism at once using multiple clamps 1421 arranged side-by-side. Then, by moving the clamping assembly 142 on the guide rail 141, multiple welding strips are unwound from the corresponding welding strip unwinding mechanism for a specific length, facilitating slitting by the corresponding welding strip cutting mechanism. When the clamping assembly 142 is away from the corresponding welding strip pressing mechanism, it is for the welding strip pulling process; when it is close to the corresponding welding strip pressing mechanism, the next set of welding strips can be pulled.

[0060] Optionally, such as Figures 10 to 11 As shown, the first strip cutting mechanism 15, the second strip cutting mechanism 25, the third strip cutting mechanism 35 and the fourth strip cutting mechanism 45 each include a multi-group cutting module 151 and a cutting drive component. The cutting drive component is connected to the multi-group cutting module 151 and is used to drive the multi-group cutting module 151 to move respectively.

[0061] Specifically, in this embodiment, the first strip cutting mechanism 15, the second strip cutting mechanism 25, the third strip cutting mechanism 35, and the fourth strip cutting mechanism 45 can be designed with the same structure. After the corresponding strip pulling mechanism pulls a set of strips of a specific length, each strip cutting mechanism cuts the strips to achieve the cutting of the first strip group, the second strip group, the third strip group, or the fourth strip group.

[0062] In practical applications, the slitting drive unit moves through the slitting module 151 to adjust the separation of each solder strip in each solder strip group while ensuring the same spacing. At the same time, it can move the corresponding solder strip to the position of the corresponding solder strip picking and placing mechanism to pick up the solder strip, which improves the reliability of each solder strip slitting mechanism in adjusting the distance between each solder strip in the corresponding solder strip group, so as to ensure that each solder strip group can be stacked on the electrode row of the battery component 600 by the corresponding solder strip picking and placing mechanism.

[0063] Optionally, such as Figure 12As shown, the first welding strip picking and placing mechanism 16, the second welding strip picking and placing mechanism 26, the third welding strip picking and placing mechanism 36 and the fourth welding strip picking and placing mechanism 46 respectively include a hook clamp module 161 and a slide rail 162; the slide rail 162 spans between the welding strip cutting mechanism and the conveying mechanism 500, the hook clamp module 161 is movably disposed on the slide rail 162 and can move along the slide rail 162 between the welding strip cutting mechanism and the conveying mechanism 500, and the hook clamp module 161 is used to clamp the first welding strip group, the second welding strip group, the third welding strip group or the fourth welding strip group.

[0064] Specifically, in this embodiment, the first ribbon picking and placing mechanism 16, the second ribbon picking and placing mechanism 26, the third ribbon picking and placing mechanism 36, and the fourth ribbon picking and placing mechanism 46 can be designed with the same structure, and their positions can be adjusted according to actual needs, without limitation. Each ribbon picking and placing mechanism uses the hook clamp module 161 to clamp the cut ribbon group, and by moving on the slide rail 162, the corresponding ribbon group can be moved to the corresponding position of the battery component 600, achieving precise placement of each ribbon group.

[0065] Optionally, such as Figure 12 As shown, the first module 100 further includes a first backup module, which includes a first backup unwinding mechanism 17, a first backup buffer mechanism 18, and a first backup clamping mechanism 19 arranged sequentially. The first welding strip pulling mechanism 14 and the first welding strip slitting mechanism 15 can be applied to the first welding strip 63 backup module; and / or, the second module 200 further includes a second backup module, which includes a second backup unwinding mechanism 27, a second backup buffer mechanism 28, and a second backup clamping mechanism 29 arranged sequentially. The second welding strip pulling mechanism 24 and the second welding strip slitting mechanism 25 can be applied to the second welding strip 64. A backup module; and / or, the third module 300 further includes a third backup module, which includes a third backup unwinding mechanism 37, a third backup buffer mechanism 38, and a third backup pressing mechanism 39 arranged in sequence, and a third welding strip pulling mechanism 34 and a third welding strip slitting mechanism 35 that can be applied to the third backup module; and / or, the fourth module further includes a fourth backup module, which includes a fourth backup unwinding mechanism 47, a fourth backup buffer mechanism 48, and a fourth backup pressing mechanism 49 arranged in sequence, and a fourth welding strip pulling mechanism 44 and a fourth welding strip slitting mechanism 45 that can be applied to the fourth backup module.

[0066] Specifically, in actual production, after the welding strips in each welding strip unwinding mechanism are used up, operators need to replace them. For example, for... Figure 1 The provided battery component 600 requires 20 rolls of welding strip in each welding strip unwinding mechanism and 4 locations to replace 80 rolls of welding strip, which is very time-consuming and affects the equipment's production capacity.

[0067] This application, by setting up a first backup module, allows the first backup unwinding mechanism 17, the first backup buffer mechanism 18, and the first backup clamping mechanism 19 to replace the first welding strip unwinding mechanism 11, the first welding strip buffer mechanism 12, and the first welding strip clamping mechanism 13 after the welding strip in the first welding strip unwinding mechanism 11 is exhausted. This ensures continued welding strip placement while allowing for the replacement of the first welding strip unwinding mechanism 11 with a new welding strip roll, ensuring operator safety. Furthermore, in the first module 100, the first welding strip pulling mechanism 14, the first welding strip cutting mechanism 15, and the first welding strip picking and placing mechanism 16 can all be simultaneously applied to the first backup module and the main module (i.e., the first welding strip unwinding mechanism 11, the first welding strip buffer mechanism 12, and the first welding strip clamping mechanism 13), reducing the number of mechanisms and equipment space while ensuring production efficiency.

[0068] Meanwhile, the second module 200, the third module 300, and the fourth module 400 can be equipped with a second backup module, a third backup module, and a fourth backup module, respectively, and their alternation method is the same as that of the first backup module. (Refer to...) Figure 12 This will not be elaborated upon further. The inclusion of backup modules increases the overall production efficiency of the welding strip arrangement equipment and improves the safety of welding strip reel changing.

[0069] Optionally, such as Figure 12 As shown, the first welding strip unwinding mechanism 11, the first welding strip buffering mechanism 12, the first welding strip pressing mechanism 13, the first spare pressing mechanism 19, the first spare buffering mechanism 18, and the first spare unwinding mechanism 17 are arranged sequentially along the conveying direction. The first welding strip pulling mechanism 14 is located between the first welding strip pressing mechanism 13 and the first spare pressing mechanism 19. The first welding strip pulling mechanism 14 includes a clamp assembly 142, which can reciprocate along the conveying direction.

[0070] refer to Figure 9 The clamp assembly 142 includes a plurality of clamps 1421 arranged side by side. Each clamp 1421 has a first clamping part 1422 and a spare clamping part 1423 at both ends. The spare clamping part 1423 is used to pull the welding strip unwound from the first spare unwinding mechanism 17, and the first clamping part 1422 is used to pull the welding strip unwound from the first welding strip unwinding mechanism 11.

[0071] Specifically, in this embodiment, the positional arrangement of each mechanism in the first module 100 enables the first welding strip pulling mechanism 14 to switch between pulling the welding strip unwound from the first backup module or pulling the welding strip unwound from the main module, achieving the reusability of some mechanisms and simplifying the number of mechanisms in the first module 100. The clamping head 1421 of the clamp assembly 142 has been improved so that both ends have a first clamping part 1422 and a backup clamping part 1423 for clamping the welding strip, enabling the first welding strip pulling mechanism 14 to pull the welding strip from two directions respectively.

[0072] Additionally, refer to Figure 12 The second module 200 also includes a second backup module, which may include a second backup unwinding mechanism 27, a second backup buffer mechanism 28 and a second backup clamping mechanism 29 arranged in sequence, and the second welding strip pulling mechanism 24 may be applied to the second backup module.

[0073] The third module 300 also includes a third backup module, which may include a third backup unwinding mechanism 37, a third backup buffer mechanism 38 and a third backup clamping mechanism 39 arranged in sequence, and the third welding strip pulling mechanism 34 may be applied to the third backup module.

[0074] The fourth module 400 also includes a fourth backup module, which may include a fourth backup unwinding mechanism 47, a fourth backup buffer mechanism 48 and a fourth backup clamping mechanism 49 arranged in sequence. The fourth welding strip mechanism 44 can be applied to the fourth backup module. The settings of each mechanism in the second module 200, the third module 300 and the fourth module 400 can refer to the first module 100 and can be adjusted adaptively, which will not be described in detail here.

[0075] Optionally, such as Figure 6 As shown, the conveying mechanism 500 includes a support platform, a straightening mechanism, and a belt mechanism. The belt is used to convey materials to the support platform, and the straightening mechanism is used to straighten the materials.

[0076] Specifically, in this embodiment, after the belt mechanism transports the battery component 600 to the support platform, its position can be adjusted by the alignment mechanism so that the battery component 600 is in the first position, thereby improving the accuracy of the subsequent placement of each welding strip group.

[0077] In another embodiment, such as Figure 6 As shown, the conveying mechanism 500 has a first station and a second station, and the conveying mechanism 500 may include a first support platform 51, a first alignment mechanism 52, a first belt mechanism 53, a second support platform 54, a second alignment mechanism 55, and a second belt mechanism 56.

[0078] The first belt mechanism 53 is used to transport the battery component 600 to the first support platform 51, and the first alignment mechanism 52 is used to align the battery component 600 on the first support platform 51 to the first work station; while the second belt mechanism 56 is used to transport the battery component 600 to the second support platform 54, and the second alignment mechanism 55 is used to align the battery component 600 on the second support platform 54 to the second work station, so as to realize the full-plate welding strip arrangement of the battery component 600.

[0079] Further, refer to Figure 6 In some embodiments, the first alignment mechanism 52 and the second alignment mechanism 55 may each include four alignment modules. The four alignment modules are respectively disposed on the side of the support platform and are used to center the battery component 600 relative to the support platform along the first direction and the second direction, so that the battery component 600 is located at the center position of the support platform, i.e., the first station or the second station.

[0080] According to a second aspect of this application, a method for arranging solder ribbons is provided, applied to the solder ribbon arranging equipment of the first aspect. The method includes: providing a battery component 600 to a conveying mechanism 500, the battery component 600 including a battery pack 62; stacking a first solder ribbon group on the battery pack 62 via a first module 100, such that the first solder ribbon group is located at a first predetermined position; and stacking a third solder ribbon group on the battery pack 62 via a third module 300, such that the third solder ribbon group is located at a third predetermined position; wherein the polarities of the first solder ribbon group and the third solder ribbon group are opposite.

[0081] Specifically, a battery component 600 is provided, which may include a glass plate 61 and two battery packs 62 disposed on the glass plate 61. Each battery pack 62 is provided with multiple electrode rows that are spaced apart along a second direction (refer to the Y direction in the figure) and extend along a first direction (i.e., the transport direction).

[0082] The first module 100 stacks first solder ribbons on each odd-numbered electrode row (and even-numbered electrode row) of the battery pack 62, positioning the first solder ribbons at a first predetermined position. Simultaneously, the third module 300 stacks third solder ribbons on each even-numbered electrode row (and odd-numbered electrode row) of the battery pack 62, positioning the third solder ribbons at a third predetermined position. The battery component 600 can be conveyed to the predetermined position via the conveying mechanism 500. (See schematic diagram of the battery component 600 for reference.) Figures 1 to 2 By grouping and stacking the first and third solder strips with opposite polarities onto the battery pack 62, the first and third solder strip groups can be individually cut and placed by different cutting and picking mechanisms, which improves the cutting and stacking efficiency of the solder strips. If the first solder strip 63 is a positive electrode solder strip, then the third solder strip is a negative electrode solder strip.

[0083] Optionally, the battery component 600 includes two battery packs 60, with a first solder ribbon group and a third solder ribbon group both stacked on one of the battery packs 62; a second solder ribbon group is stacked on the other battery pack 62 by a second module 200, so that the second solder ribbon group is located in a second predetermined position; a fourth solder ribbon group is stacked on the other battery pack 62 by a fourth module 400, so that the fourth solder ribbon group is located in a fourth predetermined position; wherein the polarities of the second solder ribbon group and the fourth solder ribbon group are opposite.

[0084] Specifically, the second module 200 stacks a second solder ribbon group on each odd-numbered electrode row (and each even-numbered electrode row) of another battery pack 62, and positions the second solder ribbon group at a second predetermined position; simultaneously, the fourth module 400 stacks a fourth solder ribbon group on each even-numbered electrode row (and each odd-numbered electrode row) of another battery pack 62, and positions the fourth solder ribbon group at a fourth predetermined position. The battery component 600 can be transported to the predetermined position via the conveying mechanism 500.

[0085] Reference diagram of battery component 600 Figures 1 to 2 By grouping and stacking the second and fourth solder strips with opposite polarities onto the same battery pack 62, the second and fourth solder strip groups can be individually cut and placed by different cutting and picking mechanisms, which improves the cutting and stacking efficiency of the solder strips. If the second solder strip 64 is a positive electrode solder strip, then the fourth solder strip is a negative electrode solder strip.

[0086] Optionally, a battery component 600 is provided to a conveying mechanism 500. The battery component 600 includes two battery packs 62. The conveying mechanism 500 positions the battery component 600 at a first station, and a first solder ribbon group is stacked on the first battery pack 62 by a first module 100, placing the first solder ribbon group at a first set position. A second solder ribbon group is stacked on the second battery pack 62 by a second module 200, placing the second solder ribbon group at a second set position. The conveying mechanism 500 positions the battery component 600 at a second station, and a third solder ribbon group is stacked on the first battery pack by a third module 300, placing the third solder ribbon group at a third set position. A fourth solder ribbon group is stacked on the first battery pack 62 by a fourth module 400, placing the fourth solder ribbon group at a fourth set position. The first and third solder ribbon groups have opposite polarities, and the second and fourth solder ribbon groups have opposite polarities.

[0087] Specifically, a battery component 600 is provided and positioned at a first work station. The battery component 600 may include a glass plate 61 and two battery packs 62 disposed on the glass plate 61. Each battery pack 62 is provided with multiple electrode rows that are spaced apart along a second direction (refer to the Y direction in the attached figure) and extend along a first direction (i.e., the conveying direction).

[0088] A first solder ribbon group is stacked on each odd-numbered or even-numbered electrode row of a battery pack 62 by a first module 100, and the first solder ribbon group is positioned at a first predetermined position. Simultaneously, a second solder ribbon group is stacked on each even-numbered or odd-numbered electrode row of another battery pack 62 by a second module 200, and the first solder ribbon group is positioned at a second predetermined position. The battery component 600 can be conveyed to a first workstation via a conveying mechanism 500. The polarities of adjacent electrode rows on the battery component 600 are opposite. The battery pack 62 includes multiple battery strings 621 arranged side-by-side along a second direction, and each battery string 621 includes multiple battery cells 622 arranged side-by-side along a first direction, the second direction being perpendicular to the first direction.

[0089] Reference diagram of battery component 600 Figures 1 to 2 By grouping and stacking the first and second solder strips 63 and 64 with the same or opposite polarity onto the two battery packs 62, the first and second solder strip groups can be individually cut and placed using different cutting and placement mechanisms, improving the efficiency of solder strip cutting and stacking. The placement of the third and fourth solder strip groups is similar to that of the first and second groups, facilitating the arrangement of the entire solder strip on the battery component 600. Wherein, if the first and second solder strips 63 and 64 are positive electrode solder strips, then the third and fourth solder strips are negative electrode solder strips.

[0090] In addition, based on Figure 1 and Figure 2 The provided battery component 600 template, by setting a first station and a second station, allows a battery component 600 to place two types of solder ribbons of the same polarity on the first and second rows of battery packs 62 at the first station, and place solder ribbons of other two polarities on the first and second rows of battery packs 62 at the second station. This improves the efficiency of solder ribbon arrangement on the entire template of the battery component 600 and simplifies the process flow.

[0091] Optionally, multiple solder strips arranged at a first spacing interval are provided to form a first solder strip group; multiple solder strips arranged at a second spacing interval are provided to form a second solder strip group; multiple solder strips arranged at a third spacing interval are provided to form a third solder strip group; and multiple solder strips arranged at a fourth spacing interval are provided to form a fourth solder strip group. This eliminates the need to adjust the length of each solder strip when cutting the solder strips, as only one length dimension needs to be met. This simplifies the process and makes it easier for the solder strip picking and placing mechanism to place the solder strips at the set position on the battery component 600, thereby improving the reliability of the solder strip placement position.

[0092] According to a third aspect of this application, a battery production line is provided, characterized in that it includes: the welding strip arrangement equipment of the first aspect.

[0093] Specifically, in this embodiment, the battery production line includes the overall arrangement of solder strips, and the arranged solder strips need to be serially welded afterwards. The solder strip arrangement equipment provided in the first aspect of this application improves the efficiency of the overall solder strip arrangement, thereby improving the efficiency of the entire battery production line and reducing production costs.
