Description

Technical Field

[0001] The present application belongs to the field of battery manufacturing technology, and specifically relates to a welding ribbon arrangement device, method and battery production line. Background Art

[0002] In the XBC battery module string welding process, the traditional battery string welding ribbons are prepared together with the battery string. A battery string has nearly a hundred welding ribbons. In most cases, a battery module is composed of 12 battery strings. The method of laying the welding ribbons one by one leads to low welding ribbon laying efficiency.

[0003] In the prior art, a plurality of welding ribbons are laid on a battery module at one time through a welding ribbon laying mechanism. However, since the positions and polarities of two adjacent welding ribbons on a battery module are usually different, the early cutting and distance adjustment of the welding ribbons are relatively complicated, resulting in that the overall laying efficiency of the welding ribbons is still not ideal.

[0004] In view of this, there is an urgent need for a device that can improve the efficiency of welding tape laying. Summary of the Invention

[0078] The following combination Figures 1-12 The present invention describes a device, method and battery production line for placing welding ribbons according to embodiments of the present application.

[0079] like Figures 1 to 12As shown, according to the first aspect of the present application, a welding strip arrangement device is provided, comprising: 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 the first side of the conveying mechanism 500 along the conveying direction (referring to the X direction in the drawings) of the conveying mechanism 500; the second module 200 and the fourth module 400 are sequentially arranged on the 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.

[0080] Specifically, in the present embodiment, the conveying mechanism 500 provided can be used to convey the battery component 600 and support the battery component 600. Based on the fact that the existing battery component 600 is usually provided with two battery groups 62, two workstations (i.e., a first workstation and a second workstation) can be arranged on the conveying mechanism 500, and the first module 100, the second module 200, the third module 300 and the fourth module 400 are arranged on the opposite sides of the conveying mechanism 500 along the conveying direction respectively, and the second module 200 is arranged opposite to the first module 100 on the two sides of the first workstation, and the fourth module is arranged opposite to the third module on the opposite sides of the second workstation, so that when the welding strip arrangement of the battery component 600 provided in the present application is performed, the first welding strip group and the second welding strip group can be placed on the two different battery groups 62 of the battery component 600 in the first workstation by the first module 100 and the second module 200 respectively, and the third welding strip group and the fourth welding strip group can be placed on the two battery groups 62 of the battery component 600 in the second workstation by the third module 300 and the fourth module 400 respectively, thereby improving the welding strip arrangement efficiency in terms of the number of battery components 600. Figure 1 And Figure 2 the conveying mechanism 500 can move the battery component 600, so that the welding strip arrangement device provided in the present application can directly and at one time complete the whole-page arrangement of the welding strip on the two battery groups of the battery component 600, thereby further improving the whole-page arrangement efficiency of the welding strip on the battery component 600.

[0081] Optionally, the first module 100 is used to arrange the first welding strip group at a first specified position of the conveying mechanism 500, the second module 200 is used to arrange the second welding strip group at a second specified position of the conveying mechanism 500, the third module 300 is used to arrange the third welding strip group at a third specified position of the conveying mechanism 500, and the fourth module 400 is used to arrange the fourth welding strip group at a fourth specified position of the conveying mechanism 500; the first welding strip group comprises a plurality of first welding strips, the second welding strip group comprises a plurality of second welding strips, the third welding strip group comprises a plurality of third welding strips, and the fourth welding strip group comprises a plurality of 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.

[0082] In practical applications, the battery component 600 generally includes a glass plate 61 and a plurality of battery cells 622 arranged on the glass plate 61, and a plurality of welding strips are generally required to be provided on the back of the plurality of battery cells 622. Figure 1 As shown, the battery component 600 is composed of 12 battery strings 621 and a glass plate 61, arranged in 2 columns and 6 rows, as shown in FIG. Figure 2 As shown, each battery string 621 consists of 12 half-cell batteries and 20 rows of welding ribbons, wherein odd-numbered rows have 6 welding ribbons and even-numbered rows have 5 welding ribbons (the number of half-cell batteries and welding ribbon rows of battery strings 621 of other types of battery components 600, as well as the number of welding ribbons in each row can be adjusted), and the position of the first welding ribbon group and the second welding ribbon group differs by 1 half-cell battery at the top.

[0083] In this embodiment, the first module 100 and the second module 200 are capable of stacking the first and second welding ribbon groups, respectively, at the first and second set positions of the conveyor mechanism 500 according to a predetermined method. When a battery assembly 600 is disposed on the conveyor mechanism 500, the first and second welding ribbon groups are stacked at the first and second set positions of the battery assembly 600, respectively. The first set position is typically located on one of the battery packs 62 on the battery assembly 600, and the second set position is typically located on another of the battery packs on the battery assembly 600. The number of first welding ribbons 63 and second welding ribbons 64 included in the first and second welding ribbon groups, respectively, can be adjusted based on the specific layout of the battery assembly 600. The polarity of the first and second welding ribbons is typically the same, but in some embodiments, can be different. Thus, the first module 100 and the second module 200 each place multiple first welding ribbons 63 and multiple second welding ribbons 64 on two battery packs 62 of the battery assembly 600, respectively. This improves the efficiency of the welding ribbon placement compared to the prior art method of placing the welding ribbons one by one.

[0084] Similarly, the third module 300 and the fourth module 400 can respectively stack the third welding ribbon group and the fourth welding ribbon group at the third set position and the fourth set position of the conveying mechanism 500 according to the set method. When the battery component 600 is placed on the conveying mechanism 500, the third welding ribbon group and the fourth welding ribbon group are respectively stacked at the third set position and the fourth set position of the battery component 600. The third set position is usually set on one of the battery groups 62 on the battery component 600, and the fourth set position is usually set on another of the battery groups 62 on the battery component 600. The number of third welding ribbons 63 and the number of fourth welding ribbons 64 that can be included in the third welding ribbon group and the fourth welding ribbon group respectively can be adjusted according to the specific version of the battery component 600. The polarities of the third welding ribbon and the fourth welding ribbon are usually the same. In some embodiments, they can also be different. The third module 100 and the fourth module 200 respectively place multiple third welding ribbons 63 and multiple fourth welding ribbons 64 on the two battery groups 62 of the battery component 600 each time. Compared with the method of placing the welding ribbons one by one in the prior art, the laying efficiency of the welding ribbons is improved.

[0085] The present application arranges 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 arranges the third and fourth solder ribbon groups through the third module and the fourth module respectively, so that the solder ribbon arrangement equipment can quickly complete the layout of the entire plate of solder ribbons on the battery component 600, thereby improving the efficiency of the entire plate of solder ribbon arrangement of the battery component 600.

[0086] In the above structure, the first module 100, the second module 200, the third module 300 and the fourth module 400 can generally include at least one group of adjustment mechanism, slitting mechanism and pick-up and placement mechanism respectively. The separate arrangement of the first welding tape group, the second welding tape group, the third welding tape group and the fourth welding tape group enables the slitting mechanism to cut out multiple first welding tapes 63 or multiple second welding tapes 64 or multiple third welding tapes or multiple fourth welding tapes of the same length at one time when slitting the welding tapes, and enables the pick-up and placement structure to clamp multiple first welding tapes 63 on the slitting mechanism at one time and directly place the multiple first welding tapes 63 at the first set position of the battery component 600 at the same time, or enables the pick-up and placement structure to clamp multiple second welding tapes 64 on the slitting mechanism at one time and directly place the multiple second welding tapes 64 at the second set position of the battery component 600 at the same time, which simplifies the adjustment process of the spacing or position between the welding tapes, and further improves the efficiency of the whole-plate welding tape arrangement of the battery component 600.

[0087] After the entire layout of the solder strips of the battery component 600 is completed by the solder strip arrangement equipment provided in this application, subsequent processes such as solder strip welding can be continued to meet the series or parallel connection between the battery cells 622 in the battery component 600.

[0088] Alternatively, as Figures 3 to 5 As shown, the welding tape arrangement equipment also includes a third module 300 and a fourth module 400, and the conveying mechanism 500 is also provided with a second workstation, and the third module 300 and the fourth module 400 are respectively arranged on opposite sides of the second workstation; the third module 300 can arrange the third welding tape group at the third set position of the second workstation, and the fourth module 400 can arrange the fourth welding tape group at the fourth set position of the second workstation; wherein, the third welding tape group includes multiple third welding tapes, and the fourth welding tape group includes multiple fourth welding tapes, and the third welding tape and the fourth welding tape are alternately and spaced apart in sequence at the third set position and the fourth set position.

[0089] Alternatively, as Figures 3 to 6 As shown, the conveying mechanism 500 is provided with a first workstation and a second workstation, and the first workstation and the second workstation are arranged in sequence along the conveying direction; the first module 100 and the second module 200 are arranged on opposite sides of the first workstation; the third module 300 and the fourth module 400 are arranged on opposite sides of the second workstation.

[0090] Specifically, in this embodiment, the first station and the second station are arranged along the conveying direction, so that the conveying mechanism 500 can convey the battery component 600 to the first station and the second station in sequence, so that after the first module 100 and the second module 200 complete the layout of the first welding tape group and the second welding tape group of the battery component 600 at the first station, it is convenient for the third module 300 and the fourth module 400 to continue to layout the third welding tape group and the fourth welding tape group of the battery component 600 moved to the second station, thereby improving the rationality of the position setting of each module, simplifying the structure of each mechanism, further improving the welding tape layout efficiency, and reducing the space occupation and equipment cost of the equipment.

[0091] In the above embodiment, the relative arrangement of the first module 100 and the second module 200, and the relative arrangement of the third module 300 and the fourth module 400 facilitate the placement of the first welding ribbon group and the second welding ribbon group on two different battery groups 62 of the battery component 600, as well as the placement of the third welding ribbon group and the fourth welding ribbon group on two different battery groups 62 of the battery component 600, while avoiding 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 of the equipment and improving the operating efficiency of the equipment.

[0092] Alternatively, 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.

[0093] Specifically, in actual applications, multiple electrode rows are usually arranged at intervals on the spliced ​​multiple battery cells 622, and each welding ribbon is stacked on a different electrode row. When the first welding ribbon 63 and the third welding ribbon 64 are alternately stacked on one of them (for example Figure 1 When the first welding strip 63 and the third welding strip 64 are connected to the plurality of electrode rows on the battery pack 62 (the right column in the middle), the polarity of the first welding strip 63 and the third welding strip 64 are opposite. At the same time, the second welding strip and the fourth welding strip are alternately stacked on another (for example Figure 1 When multiple electrode rows are arranged on a battery pack 62 (the left column in the middle), the second and fourth welding ribbons have opposite polarities, while the first welding ribbon and the second welding ribbon 64 generally have the same polarity, and the third and fourth welding ribbons 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 generally designed to be identical, simplifying the structure of the entire welding ribbon arrangement device without affecting the operation of the entire device.

[0094] Alternatively, as Figures 3 to 5 As shown, the first module 100 includes a first solder ribbon unwinding mechanism 11, a first solder ribbon buffer mechanism 12, a first solder ribbon clamping mechanism 13, a first solder ribbon pulling mechanism 14, a first solder ribbon slitting mechanism 15 and a first solder ribbon picking and placing mechanism 16; wherein, the first solder ribbon unwinding mechanism 11, the first solder ribbon buffer mechanism 12, the first solder ribbon clamping mechanism 13 and the first solder ribbon pulling mechanism 14 are arranged in sequence so that the first solder ribbon slitting mechanism 15 can cut out a first solder ribbon group, and the first solder ribbon picking and placing mechanism 16 is used to place the first solder ribbon group to a first set position.

[0095] The second module 200 includes a second solder ribbon unwinding mechanism 21, a second solder ribbon buffer mechanism 22, a second solder ribbon clamping mechanism 23, a second solder ribbon pulling mechanism 24, a second solder ribbon slitting mechanism 25 and a second solder ribbon picking and placing mechanism 26; wherein, the second solder ribbon unwinding mechanism 21, the second solder ribbon buffer mechanism 22, the second solder ribbon clamping mechanism 23 and the second solder ribbon pulling mechanism 24 are arranged in sequence so that the second solder ribbon slitting mechanism 25 can cut out a second solder ribbon group, and the second solder ribbon picking and placing mechanism 26 is used to place the second solder ribbon group to a second set position.

[0096] Specifically, in this embodiment, the first solder strip unwinding mechanism 11 in the first module 100 is used to unwind multiple solder strips. The number of solder strips unwound depends on the specific version of the battery component 600, for example. Figure 1In the battery component 600, the first ribbon unwinding mechanism 11 can unwind 20 ribbons. The 20 unwound ribbons pass through the first ribbon buffer mechanism 12 and enter the first ribbon clamping mechanism 13. The first ribbon pulling mechanism 14 clamps the 20 ribbons and moves them a specific distance. The first ribbon clamping mechanism 13 then clamps the ribbons, allowing the first ribbon slitting mechanism 15 to cut the 20 ribbons. The cut 20 ribbons form a first ribbon group. The first ribbon placement mechanism 16 then clamps or absorbs the cut first ribbon group, moves it above the battery component 600, and places the first ribbon group at the first set position of the battery component 600. After cutting the first ribbon group, the first ribbon slitting mechanism 15 can also adjust the spacing between the ribbons to meet the placement requirements of the first ribbon group.

[0097] In the above structure, the first ribbon clamping mechanism 13 can be equipped with multiple guide grooves to ensure the accurate positioning of the 20 ribbons. The specific distance moved by the first ribbon pulling mechanism 14 corresponds to the total length of the first ribbon group. After slitting the ribbons, the first ribbon slitting mechanism 15 can also adjust the distance between the individual ribbons to match the spacing of the electrode rows on the battery component 600. Furthermore, the sequential arrangement of the first ribbon unwinding mechanism 11, the first ribbon buffer mechanism 12, the first ribbon clamping mechanism 13, and the first ribbon pulling mechanism 14 facilitates the pulling of the ribbons by the first ribbon pulling mechanism 14, thereby improving the reliability of the first module 100.

[0098] Furthermore, the configuration and operation of the various mechanisms in the second module 200 are similar to those in the first module 100 and are not described in detail here. It should be noted that the positions of the first solder ribbon pick-up and placement mechanism 16 and the second solder ribbon pick-up and placement mechanism 26 at the first station can be staggered to avoid interference when placing the first and second solder ribbon groups, thereby improving the reliability of the entire device.

[0099] Alternatively, as Figures 3 to 5 As shown, the third module 300 includes a third welding ribbon unwinding mechanism 31, a third welding ribbon buffer mechanism 32, a third welding ribbon clamping mechanism 33, a third welding ribbon pulling mechanism 34, a third welding ribbon slitting mechanism 35 and a third welding ribbon taking and placing mechanism 36; wherein, the third welding ribbon unwinding mechanism 31, the third welding ribbon buffer mechanism 32, the third welding ribbon clamping mechanism 33 and the third welding ribbon pulling mechanism 34 are arranged in sequence so that the third welding ribbon slitting mechanism 35 can cut out a third welding ribbon group, and the third welding ribbon taking and placing mechanism 36 is used to place the third welding ribbon group to a third set position.

[0100] The fourth module 400 includes a fourth welding ribbon unwinding mechanism 41, a fourth welding ribbon buffer mechanism 42, a fourth welding ribbon clamping mechanism 43, a fourth welding ribbon pulling mechanism 44, a fourth welding ribbon slitting mechanism 45 and a fourth welding ribbon picking and placing mechanism 46; wherein, the fourth welding ribbon unwinding mechanism 41, the fourth welding ribbon buffer mechanism 42, the fourth welding ribbon clamping mechanism 43 and the fourth welding ribbon pulling mechanism 44 are arranged in sequence so that the fourth welding ribbon slitting mechanism 45 can cut out a fourth welding ribbon group, and the fourth welding ribbon picking and placing mechanism 46 is used to place the fourth welding ribbon group to a fourth set position.

[0101] Specifically, in this embodiment, the working mode and setting position 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 no further description is given. It should be noted that in order to ensure that the first welding ribbon group, the second welding ribbon group, the third welding ribbon group and the fourth welding ribbon group are accurately placed at the corresponding positions of the battery component 600, the setting position of each mechanism in each module can be matched according to actual needs, with reference to Figure 4 .

[0102] Alternatively, as Figures 3 to 5 As shown, the first welding ribbon unwinding mechanism 11, the first welding ribbon buffer mechanism 12, the first welding ribbon clamping mechanism 13, the first welding ribbon pulling mechanism 14, the third welding ribbon unwinding mechanism 31, the third welding ribbon buffer mechanism 32, the third welding ribbon clamping mechanism 33 and the third welding ribbon pulling mechanism 34 are arranged in sequence along the conveying direction; the fourth welding ribbon unwinding mechanism 41, the fourth welding ribbon buffer mechanism 42, the fourth welding ribbon clamping mechanism 43, the fourth welding ribbon pulling mechanism 44, the second welding ribbon unwinding mechanism 21, the second welding ribbon buffer mechanism 22, the second welding ribbon clamping mechanism 23 and the second welding ribbon pulling mechanism 24 are arranged in sequence along the opposite direction of the conveying direction.

[0103] Specifically, in this embodiment, based on Figure 1 The provided version of the battery component 600, corresponding to each mechanism of each module can be arranged according to the above-mentioned position, so that the first welding tape pulling mechanism 14 and the third welding tape pulling mechanism 34 can respectively smoothly pull the multiple welding tapes of the first welding tape unwinding mechanism 11 and the multiple welding tapes unwound by the third welding tape unwinding mechanism 31, and the second welding tape pulling mechanism 24 and the fourth welding tape pulling mechanism 44 can respectively smoothly pull the multiple welding tapes of the second welding tape unwinding mechanism 21 and the multiple welding tapes unwound by the fourth welding tape unwinding mechanism 41, and at the same time, each welding tape picking and placing mechanism can place the corresponding welding tape group at the corresponding position of the battery component 600, so as to realize the placement of the welding tape of the entire version of the battery component 600.

[0104] Alternatively, as Figure 7As shown, the first welding ribbon clamping mechanism 13, the second welding ribbon clamping mechanism 23, the third welding ribbon clamping mechanism 33 and the fourth welding ribbon clamping mechanism 43 respectively include a first pressing piece 131, a second pressing piece 132 and a clamping driving piece 133; a plurality of guide grooves 1321 arranged side by side are provided on the first pressing piece 131 or the second pressing piece 132, and the guide grooves 1321 are used to place the welding ribbons; the clamping driving piece 133 is connected to the first pressing piece 131, and is used to make the first pressing piece 131 close to or away from the second pressing piece 132.

[0105] Specifically, in this embodiment, the first soldering ribbon pressing mechanism 13, the second soldering ribbon pressing mechanism 23, the third soldering ribbon pressing mechanism 33, and the fourth soldering ribbon pressing mechanism 43 can be designed to have the same structure. When pressing the soldering ribbon, each soldering ribbon pressing mechanism can drive the first pressing member 131 toward the second pressing member 132 through the pressing driving member 133 to press the soldering ribbon in the guide groove 1321, thereby facilitating the subsequent slitting of the corresponding soldering ribbon by each soldering ribbon slitting mechanism.

[0106] After the ribbon is slit, the clamping driver 133 can loosen the ribbon 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, thereby facilitating the ribbon removal and placement mechanisms to grip the slit ribbon. When the ribbon groups extend in the first direction, the guide grooves 1321 also extend in the first direction. The clamping driver 133 can be a cylinder or a motor, and its connection to the first clamping member 131 can also be achieved through a transmission element, again without limitation.

[0107] Alternatively, as Figure 8 As shown, the first welding tape pulling mechanism 14, the second welding tape pulling mechanism 24, the third welding tape pulling mechanism 34 and the fourth welding tape pulling mechanism 44 respectively include a guide rail 141 and a clamp assembly 142 movably arranged 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 tape, and the clamp assembly 142 can approach or move away from the corresponding welding tape clamping mechanism along the guide rail 141.

[0108] Specifically, in this embodiment, the first, second, third, and fourth ribbon pulling mechanisms 14, 24, 34, and 44 can be designed to have identical structures. The clamp assembly 142 of each ribbon pulling mechanism can simultaneously clamp multiple ribbons entering the corresponding ribbon clamping mechanism using multiple chucks 1421 arranged side by side. Furthermore, by moving the clamp assembly 142 along the guide rail 141, the multiple ribbons are unwound from the corresponding ribbon unwinding mechanism to a specific length, facilitating slitting by the corresponding ribbon slitting mechanism. When the clamp assembly 142 is away from the corresponding ribbon clamping mechanism, the ribbon is being pulled. When it is closer to the corresponding ribbon clamping mechanism, the next set of ribbons can be pulled.

[0109] Alternatively, as Figures 10 and 11 As shown, the first welding ribbon slitting mechanism 15, the second welding ribbon slitting mechanism 25, the third welding ribbon slitting mechanism 35 and the fourth welding ribbon slitting mechanism 45 respectively include a multi-group slitting module 151 and a slitting drive, the slitting drive is connected to the multi-group slitting module 151, and the slitting drive is used to drive the multi-group slitting module 151 to move respectively.

[0110] Specifically, in this embodiment, the first ribbon slitting mechanism 15, the second ribbon slitting mechanism 25, the third ribbon slitting mechanism 35, and the fourth ribbon slitting mechanism 45 can be designed to have the same structure. After the corresponding ribbon pulling mechanism pulls a group of ribbons of a specific length, each ribbon slitting mechanism slits the ribbons to achieve slitting of the first ribbon group, the second ribbon group, the third ribbon group, or the fourth ribbon group.

[0111] In actual application, the slitting drive component drives the slitting module 151 to move separately to adjust the separation between each welding ribbon in each welding ribbon group and ensure the same spacing, and at the same time can move the corresponding welding ribbon to the position of the corresponding welding ribbon picking and placing mechanism to pick up the welding ribbon, thereby improving the reliability of each welding ribbon slitting mechanism for adjusting the distance between each welding ribbon in the corresponding welding ribbon group, so as to ensure that each welding ribbon group can be stacked on the electrode row of the battery component 600 by the corresponding welding ribbon picking and placing mechanism.

[0112] Alternatively, as Figure 12 As shown, the first solder tape picking and placing mechanism 16, the second solder tape picking and placing mechanism 26, the third solder tape picking and placing mechanism 36 and the fourth solder tape picking and placing mechanism 46 respectively include a hook clamp module 161 and a slide rail 162; the slide rail 162 is arranged between the solder tape slitting mechanism and the conveying mechanism 500, and the hook clamp module 161 is movably arranged on the slide rail 162 and can move along the slide rail 162 between the solder tape slitting mechanism and the conveying mechanism 500, and the hook clamp module 161 is used to clamp the first solder tape group, the second solder tape group, the third solder tape group or the fourth solder tape group.

[0113] Specifically, in this embodiment, the first ribbon pick-up and placement mechanism 16, the second ribbon pick-up and placement mechanism 26, the third ribbon pick-up and placement mechanism 36, and the fourth ribbon pick-up and placement mechanism 46 can be designed to have the same structure. Their locations can be adjusted according to actual needs and are not limited here. Each ribbon pick-up and placement mechanism uses a hook clamp module 161 to clamp the slit ribbon group and, by moving on the slide rail 162, allows the corresponding ribbon group to be moved to the corresponding position of the battery component 600, thereby achieving precise placement of each ribbon group.

[0114] Alternatively, as Figure 12As shown, the first module 100 also includes a first spare module, the first spare module includes a first spare unwinding mechanism 17, a first spare buffer mechanism 18 and a first spare pressing mechanism 19 arranged in sequence, and the first welding tape pulling mechanism 14 and the first welding tape slitting mechanism 15 can be applied to the first welding tape 63 spare module; and / or, the second module 200 also includes a second spare module, the second spare module includes a second spare unwinding mechanism 27, a second spare buffer mechanism 28 and a second spare pressing mechanism 29 arranged in sequence, the second welding tape pulling mechanism 24 and the second welding tape slitting mechanism 25 can be applied to the second welding tape 64 A backup module; and / or, the third module 300 also includes a third backup module, the third backup module includes 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 tape pulling mechanism 34 and the third welding tape slitting mechanism 35 can be applied to the third backup module; and / or, the fourth module also includes a fourth backup module, the fourth backup module includes a fourth backup unwinding mechanism 47, a fourth backup buffer mechanism 48 and a fourth backup clamping mechanism 49 arranged in sequence, and the fourth welding tape pulling mechanism 44 and the fourth welding tape slitting mechanism 45 can be applied to the fourth backup module.

[0115] Specifically, in the actual production process, after the soldering tape of each soldering tape unwinding mechanism is used up, the operator needs to replace the soldering tape, for example, Figure 1 The provided version of the battery component 600 requires each soldering ribbon unwinding mechanism to have 20 rolls of soldering ribbon and 4 locations. Replacing 80 rolls of soldering ribbon is very time-consuming and affects the production capacity of the equipment.

[0116] The present application sets a first backup module so that after the first ribbon unwinding mechanism 11 runs out of ribbon, the first backup unwinding mechanism 17, the first backup buffer mechanism 18 and the first backup clamping mechanism 19 can replace the first ribbon unwinding mechanism 11, the first ribbon buffer mechanism 12 and the first ribbon clamping mechanism 13, thereby ensuring that the ribbon placement can continue. At the same time, while ensuring the safety of the operator, a new ribbon roll can be replaced for the first ribbon unwinding mechanism 11. In addition, in the first module 100, the first ribbon pulling mechanism 14 and the first ribbon slitting mechanism 15, as well as the first ribbon taking and placing mechanism 16 can all be applied to the first backup module and the main module (i.e., the first ribbon unwinding mechanism 11, the first ribbon buffer mechanism 12 and the first ribbon clamping mechanism 13) at the same time, which not only reduces the number of mechanisms and the space occupied by equipment, but also ensures production efficiency.

[0117] At the same time, the second module 200, the third module 300, and the fourth module 400 can be respectively set up as the second backup module, the third backup module, and the fourth backup module at the same time. The alternation method is the same as that of the first backup module. Figure 12The provision of each spare module makes the production efficiency of the entire welding ribbon arrangement equipment higher and improves the safety of welding ribbon reel replacement.

[0118] Alternatively, as Figure 12 As shown, the first welding ribbon unwinding mechanism 11, the first welding ribbon buffer mechanism 12, the first welding ribbon clamping mechanism 13, the first standby clamping mechanism 19, the first standby buffer mechanism 18, and the first standby unwinding mechanism 17 are arranged in sequence along the conveying direction, and the first welding ribbon pulling mechanism 14 is located between the first welding ribbon clamping mechanism 13 and the first standby clamping mechanism 19; the first welding ribbon pulling mechanism 14 includes a clamp assembly 142, and the clamp assembly 142 can move back and forth along the conveying direction.

[0119] refer to Figure 9 The clamp assembly 142 includes a plurality of clamps 1421 arranged side by side, and each clamp 1421 is respectively provided with a first clamping portion 1422 and a spare clamping portion 1423 at both ends; wherein the spare clamping portion 1423 is used to pull the soldering ribbon unwound from the first spare unwinding mechanism 17, and the first clamping portion 1422 is used to pull the soldering ribbon unwound from the first soldering ribbon unwinding mechanism 11.

[0120] Specifically, in this embodiment, the positions of the various mechanisms in the first module 100 enable the first ribbon pulling mechanism 14 to switch between pulling the ribbon unwound from the first backup module or pulling the ribbon unwound from the main module, thereby achieving the reusability of some mechanisms and simplifying the number of mechanisms in the first module 100. Specifically, the clamping head 1421 of the clamp assembly 142 has been improved, such that both ends thereof have a first clamping portion 1422 and a backup clamping portion 1423 for clamping the ribbon, enabling the first ribbon pulling mechanism 14 to pull the ribbon from two directions.

[0121] In addition, reference 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 can be applied to the second backup module.

[0122] The third module 300 further includes a third backup module, which may include a third backup unwinding mechanism 37, a third backup buffer mechanism 38 and a third backup pressing mechanism 39 arranged in sequence, and the third welding strip pulling mechanism 34 may be applied to the third backup module.

[0123] 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, and the fourth welding strip pulling 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 adaptively adjusted, which will not be elaborated here.

[0124] Alternatively, as Figure 6 As shown, the conveying mechanism 500 includes a supporting platform, a straightening mechanism and a belt mechanism. The belt is used to convey materials to the supporting platform, and the straightening mechanism is used to straighten the materials.

[0125] Specifically, in this embodiment, after the belt mechanism transports the battery component 600 to the support platform, its position can be adjusted by the correction mechanism so that the battery component 600 is located in the first position, thereby improving the position accuracy of the subsequent placement of each welding ribbon group.

[0126] In another embodiment, Figure 6 As shown, the conveying mechanism 500 has a first workstation and a second workstation, and the conveying mechanism 500 may correspondingly include a first supporting platform 51, a first correcting mechanism 52, a first belt mechanism 53, a second supporting platform 54, a second correcting mechanism 55 and a second belt mechanism 56.

At the same time, the third welding strip group is stacked on each even electrode row (each odd electrode row) of the battery pack 62 by the third module 300, and the third welding strip group is located at the third set position. The battery component 600 can be conveyed to the set position by the conveying mechanism 500. The layout diagram of the battery component 600 is shown in Figures 1 to 2 The first welding strip 63 and the third welding strip are grouped and stacked on the battery pack 62 with opposite polarities, so that the first welding strip group and the third welding strip group can be individually cut and placed by different cutting mechanisms and taking and placing mechanisms, thereby improving the cutting and stacking efficiency of the welding strips. If the first welding strip 63 is a positive electrode welding strip, the third welding strip is a negative electrode welding strip.

[0132] Alternatively, the battery component 600 comprises two battery packs 60, and the first welding strip group and the third welding strip group are both stacked on one of the battery packs 62.

Figures 1 to 2 By grouping the second welding ribbon 64 and the fourth welding ribbon with opposite polarities and stacking them on the same battery pack 62, the second welding ribbon group and the fourth welding ribbon group can be separately cut and placed by different cutting mechanisms and placement mechanisms, thereby improving the efficiency of cutting and stacking the welding ribbons. Among them, if the second welding ribbon 64 is a positive electrode welding ribbon, the fourth welding ribbon is a negative electrode welding ribbon.

[0136] Specifically, a battery component 600 is provided and located at a first workstation. The battery component 600 may include a glass plate 61 and two battery groups 62 arranged on the glass plate 61. Each battery group 62 is provided with a plurality of electrode rows arranged at intervals along a second direction (refer to the Y direction in the accompanying drawing) and extending along a first direction (i.e., the conveying direction).
