[0041] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the embodiments in the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0042] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0043] like Figure 1 As shown, the present application provides a welding strip arrangement device, comprising:

[0044] A carrying module 100, the carrying module 100 is used to carry a substrate and a plurality of battery cells arranged on the substrate; the substrate generally includes a rigid board and a flexible layer located on the rigid board, the rigid board is, for example, glass, and the flexible layer is, for example, an EVA film or a POE film;

[0045] A solder strip processing module, the solder strip processing module includes a transfer table assembly 200 and a solder strip conveying assembly 300 located above the transfer table assembly;

[0046] Among them, the length direction of the contour of the carrying module 100 in the horizontal plane is the first direction, and the width direction is the second direction. Specifically, because the multiple battery cells arranged on the substrate are generally in the form of a rectangular matrix, that is, the outer contour of the multiple battery cells after being arranged in the horizontal plane is a rectangle with long sides and short sides. Correspondingly, in order to better carry the battery cells, the outer contour of the carrying module 100 in the horizontal plane can be regarded as a rectangle, also with long sides and short sides. The length direction of the carrying module 100 is the direction parallel to the direction in which the long side extends, and the width direction is the direction parallel to the direction in which the short side extends. The length direction of the carrying module 100 is parallel to the long side direction of the arranged multiple battery cells, and the width direction of the carrying module 100 is parallel to the short side direction of the arranged multiple battery cells. The length direction and width direction of the carrying module 100 are selected here as direction references, mainly to illustrate that the solder strip handling assembly 300 can carry multiple solder strips corresponding to at least one row of battery cells to the substrate at one time.

[0047] The transfer table assembly 200 is used to carry multiple solder strips arranged side by side. The solder strip transport assembly 300 includes a transport drive mechanism 310 and multiple transport parts arranged in a matrix and connected to the transport drive mechanism 310. The multiple transport parts arranged in a matrix are used to transport multiple solder strips of the required number corresponding to at least one row of battery cells to the carrier module 100, and when the transport drive mechanism 310 drives the multiple transport parts to move to the surface of the carrier module 100 at the same time, the row arrangement direction of the multiple transport parts arranged in a matrix is ​​parallel to the first direction.

[0048] In this patent, since the row arrangement direction of multiple transport members is parallel to the first direction when the multiple transport members move to the surface of the supporting module, the solder strips corresponding to a row of battery cells in the battery assembly can be arranged at one time, thereby greatly improving the solder strip arrangement capacity.

[0049] More specifically, the welding strips carried by the transfer table assembly 200 can extend along the first direction or along the second direction, preferably along the first direction, and the multiple welding strips are arranged along the second direction. Among them, the multiple welding strips carried by the transfer table assembly 200 can be pulled out from the welding strip feeding assembly 500 and not yet cut, or can be pulled out to the required length and cut, but the welding strip conveying assembly 300 conveys the already cut welding strips. After the welding strips are cut, it can be considered that the multiple welding strips carried by the transfer table assembly 200 include multiple welding strip groups extending along the first direction, and the multiple welding strips in each welding strip group are arranged side by side along the second direction. Generally, one welding strip group corresponds to the number of welding strips required for one battery cell.

[0050] More specifically, the structure of the supporting module 100 can at least support a substrate and a plurality of battery cells arranged in a matrix. As an example, it at least includes a supporting member. Preferably, the number of supporting members is multiple, and the multiple supporting members are arranged at intervals along the second direction. Each supporting member is in the shape of an elongated strip, and the extension direction is the first direction. The specific structure of the transfer table assembly 200 can be referred to the example below, which can support a plurality of welding strips required for at least one row of battery cells. Among them, the transport drive mechanism 310 can be a manipulator or a linear drive mechanism. The linear drive mechanism can include a motor or a cylinder, a gantry, and a slide rail, etc., so that the motor or cylinder drives multiple transport members to move along the slide rail in the horizontal direction or the height direction. The transport member can be a suction cup or a clamp.

[0051] As another embodiment, the transporting member is a suction cup or a clamping jaw 10. When a suction cup is used, the solder strip is taken and placed by adsorption force and breaking the vacuum; when the clamping jaw 10 is used, the solder strip is taken and placed by driving the clamping jaw 10 to open and close.

[0052] As another embodiment, the transfer table assembly 200 is located above the carrier module 100 or on the side of the long side of the carrier module 100. Preferably, the transfer table assembly 200 is located on the side of the long side of the carrier module 100 to facilitate operation and welding ribbon transportation. The transportation drive mechanism 310 is a robot or a linear drive mechanism.

[0053] As another embodiment, the transport drive mechanism 310 is a linear drive mechanism, which includes a lifting drive actuator and a horizontal drive actuator connected to the lifting drive actuator, and multiple transport members are simultaneously connected to the horizontal drive actuator or one of the lifting drive actuators. The lifting drive actuator and the horizontal drive actuator can both be linear motors, that is, when transporting the solder strip, the transport drive mechanism 310 can move the solder strip up and down, or can move the solder strip horizontally, according to Figure 1In the example shown, the horizontal driving actuator moves along the second direction with multiple transporting parts, so that it can go back and forth between the bearing module 100 and the transfer table assembly 200, and the lifting driving actuator moves multiple transporting parts close to or away from the transfer table assembly 200 or close to or away from the bearing module 100. Therefore, the transport driving mechanism 310 can carry multiple transporting parts down to the surface of the transfer table assembly 200 to obtain the cut solder strip, and then carry multiple transporting parts up and move along the second direction to the position where the solder strip needs to be placed on the bearing module 100, and then carry multiple transporting parts down to the surface of the bearing module 100 to place the solder strip on the battery cell on the substrate. Preferably, multiple transporting parts are connected to the lifting driving actuator, and the lifting driving actuator is connected to the horizontal driving actuator. Further, considering that the number of multiple transporting parts is large and the size is large, the transport driving mechanism 310 includes a gantry as a support and a slide rail in addition to the linear motor, which facilitates the installation and movement of the driving actuator and multiple transporting parts.

[0054] As another example, Figure 2 As shown, a plurality of transport members arranged in a matrix can be divided into at least one transport unit 20, and one transport unit 20 is used to transport a plurality of welding strips required for a row of battery cells; wherein the transport member is a clamp 10, and one transport unit 20 includes a plurality of clamp groups 30 arranged side by side, and the number of clamp groups 30 in the transport unit 20 is not greater than the number of battery cells in a row of battery cells, and one clamp group 30 is used to transport the number of welding strips required for one battery cell. That is to say, the number of clamp groups 30 can be equal to the number of battery cells in a row of battery cells, or less than the number of battery cells in a row of battery cells. When less than, the welding strips required for some battery assemblies can be placed first, and then the welding strips required for the remaining battery assemblies can be placed later, which is flexible.

[0055] Furthermore, the plurality of transport members arranged in a matrix can be further divided into at least two transport units 20, and the arrangement direction of the two transport units 20 is perpendicular to the arrangement direction of the plurality of side-by-side arranged clamping jaws 30 in one transport unit 20, for example Figure 2 As shown, the clamping jaws 30 are arranged side by side along the first direction, and at least two conveying units 20 are arranged side by side along the second direction. When there are multiple conveying units, the required number of solder strips for multiple rows of battery cells can be conveyed at one time, that is, the solder strips corresponding to multiple rows of battery cells can be arranged at the same time; further, when the carrier module 100 is provided with a transfer table assembly 200 and a solder strip conveying assembly 300 on both sides (both sides of the long side) along the second direction and the assemblies on both sides are respectively responsible for arranging half of the number of solder strips required for the entire battery assembly, only one solder strip arranging station is required for simultaneous arrangement, which saves the space occupied by the equipment and ensures production capacity because the solder strips corresponding to multiple rows of battery cells can be conveyed by multiple conveying units 20 at a time.

[0056] As another example, Figure 2 As shown, a plurality of clamping jaws 30 in a transport unit 20 are arranged side by side along a first direction, and the clamping jaws 30 include a plurality of clamping jaw units 40 arranged side by side along a second direction, and each clamping jaw unit 40 includes at least two clamping jaws 10 separately arranged along the first direction, and a clamping jaw unit 40 is used to clamp a welding strip extending along the first direction; wherein the clamping jaws 10 are opened and closed along the second direction to clamp the welding strip from both sides of the welding strip. When there are two clamping jaws 10, the two clamping jaws 10 clamp from both ends of the welding strip, and when there are more, such as three, there is another clamping jaw 10 that can also clamp from the middle position of the welding strip.

[0057] As another example, Figure 2 , Figure 3 As shown, the clamping jaw 10 includes a fixed jaw 101 and a movable jaw 102 which are relatively opened and closed, and the fixed jaw 101 is hinged to the movable jaw 102. The multiple clamping jaws 10 in the clamping jaw group 30 can also be divided into at least two rows of clamping jaw mechanisms 50 which are separately arranged along the first direction. The clamping jaw mechanism 50 includes multiple clamping jaws 10 arranged along the second direction, wherein the number of clamping jaw mechanisms 50 in a clamping jaw group 30 corresponds to the number of clamping jaws 10 in a clamping jaw unit 40; the welding strip handling assembly 300 also includes a base 330, and each clamping jaw group 30 also includes at least two clamping jaw plates 320 which are liftably connected to the base 330, at least two clamping jaw plates 330 are separately arranged along the first direction, and one clamping jaw plate 320 corresponds to one row of clamping jaw mechanisms 50, and the clamping jaw plate 320 includes multiple driving teeth arranged along the second direction, and the driving teeth are located on the side of the movable jaw 102, and one driving tooth corresponds to driving the movable jaw 102 in one or two clamping jaws 10 to open and close relative to the fixed jaw 101. By providing the clamping jaw insert plate 320, all the moving jaws 102 in a row of clamping jaw mechanisms 50 can move simultaneously, thereby improving work efficiency and improving the consistency of the clamping jaws' movements.

[0058] Specifically, the structure for opening and closing the movable claw 102 and the fixed claw 101 can be that the fixed claw 101 is connected to the base 330, and the fixed claw 101 and the movable claw 102 are hinged in, for example, that the fixed claw 101 and the movable claw 102 are connected by a cylindrical pin, and a spring is arranged between the fixed claw 101 and the movable claw 102 to facilitate clamping the welding strip after the clamp 10 is reset, wherein the fixed claw 101 and the cylindrical pin have a clearance fit, and the movable claw 102 and the cylindrical pin have an interference fit, and the spring is attached to the fixed claw 101 and the movable claw 102.

[0059] More specifically, the clamping jaw plate 320 can not only reciprocate and drive the moving jaw 102 to move along the second direction to realize the opening and closing of the fixed jaw 101 and the moving jaw 102, but also move up and down to realize the opening and closing of the fixed jaw 101 and the moving jaw 102. In this embodiment, the clamping jaw plate 320 preferably moves up and down, so that the operation is more flexible and the arrangement can be diversified. Furthermore, the clamping jaw plate 320 can be connected to the base 330 through a guide member (not shown in the figure), wherein the guide member can be slidably connected to the base 330 in the vertical direction, and the clamping jaw plate 320 is connected to the guide member, and the guide member can be used to limit the lifting movement of the clamping jaw plate 320 in the vertical direction, and make the movement of the clamping jaw plate 320 more stable. When the clamping jaw plate 320 drives the moving jaw 102 to move in the form of up and down movement, such as Figure 3 As shown, the protruding edge 321 of the driving tooth moves and contacts with the upper edge 111 of the moving claw 102. When the jaw plate 320 descends, the contour of the protruding edge 321 of the driving tooth drives the moving claw 102 to rotate slightly around the cylindrical pin, and the jaw 10 releases the welding strip; when the jaw plate 320 rises, the elastic force of the spring in the jaw 10 causes the moving claw 102 to rotate slightly in the opposite direction around the cylindrical pin, so that the upper edge 321 of the moving claw 102 fits with the protruding edge 321 of the driving tooth, limiting the swing stroke of the moving claw 102, and then the jaw 10 closes and clamps the welding strip. Of course, this is just one example, and any structure that can realize the jaw plate 320 to drive the moving claw 102 to open and close relative to the fixed claw 101 in the form of up and down movement is within the protection scope. Further, the driving mechanism that drives the jaw plate 320 to rise and fall is described in detail below.

[0060] also, Figure 3 It is just an example of a structural diagram in which a driving tooth drives a clamping jaw 10 to move. When one driving tooth drives two clamping jaws 10 at the same time, the moving claws 102 of the two adjacent clamping jaws 10 can be arranged adjacent to each other and each driving tooth is located between the moving claws 102 of the two adjacent clamping jaws 10.

[0061] As another example, Figure 4 As shown, the fixed claw 101 and the moving claw 102 are used to clamp the ends of the welding strip, respectively including a first reference surface 1011 and a second reference surface 1021. Both the first reference surface 1011 and the second reference surface 1021 are planes. The moving claw 102 moves toward the fixed claw 101. When clamping the welding strip, the first reference surface 1011 and the second reference surface 1021 are parallel to each other and both are perpendicular to the horizontal plane, so that all welding strips use the first reference surface 1011 as the positioning surface. At the same time, the first reference surface 1011 and the second reference surface 1021 clamp the welding strip from both sides of the welding strip to prevent the welding strip from moving in the horizontal direction. Since all welding strips in the welding strip handling assembly 300 use the same reference surface as the positioning surface, the position arrangement accuracy can be improved when the welding strips are arranged.

[0062] As another example, Figure 5 As shown, the welding ribbon handling assembly 300 also includes a first driving mechanism, which includes a first power actuator (not shown in the figure) and a first connecting driving member 340 connected to the first power actuator, and the first connecting driving member 340 drives the clamping plates 320 in all the clamping jaw groups 30 to rise or fall at the same time. Among them, the first power actuator can be a cylinder or a motor. The structure of the first connecting driving member 340 can be diversified. According to actual needs, the lifting and lowering movement of the clamping jaw plate 320 can be achieved by driving the first connecting driving member 340 to move up and down by the first power actuator, or by driving the first connecting driving member 340 to move horizontally (for example, a protruding structure is provided on the top of the clamping jaw plate 320 and a lifting guide is provided for the clamping jaw plate 320) to achieve the lifting and lowering movement of the clamping jaw plate 320. The lifting and lowering movement of the clamping jaw plate 320 can also be achieved by driving the pushing member in the first connecting driving member 340 that is in sliding contact with the clamping jaw plate 320 to rotate. As one example, Figure 5 As shown, the first connecting driving member 340 includes a driving frame 341 whose length covers the length of a transport unit 20, and a plurality of pushing members 342 connected to the driving frame 341, and the positions of the pushing members 342 correspond to the positions of the clamping jaws 30 one by one (for example Figure 5 The two pushing members 342 can also be connected as one to ensure that they correspond to two clamping plates at the same time, or one clamping jaw group 30 corresponds to, for example, four pushing members 342, and one clamping jaw plate 320 corresponds to two pushing members 342). Then, the pushing member 342 can simultaneously push at least two clamping jaw plates 320 in one clamping jaw group 30 to rise and fall at the same time. Moreover, because all pushing members 342 are connected to the driving frame 341, a power actuator drives the first connecting driving member 340 to move, which can simultaneously drive all the clamping jaw plates 320 in the welding strip handling assembly 300 to move at the same time, thereby driving all the clamping jaws 10 in the welding strip handling assembly 300 to open and close, clamp and release the welding strip, thereby improving the action consistency of the welding strip handling assembly 300, and the structure is simple, which is conducive to improving the welding strip arrangement accuracy.

[0063] As another example, Figure 6As shown, the solder tape transport assembly 300 also includes a first pressing mechanism, which is divided into a plurality of first pressing units 350, the same number as the clamping jaw group 30, and the plurality of first pressing units 350 are arranged along a first direction. The first pressing unit 350 is located between two columns of clamping jaw mechanisms 50 of the corresponding clamping jaw group 30, and is used to press down the solder tape before the clamping jaw 10 releases the solder tape, so that before releasing the solder tape, a downward pressure can be applied to the solder tape to pre-fix the solder tape on the battery cell and then release the solder tape. Therefore, the solder tape is not easily shifted during arrangement, and the arrangement accuracy is higher. At the same time, it can also avoid the solder tape being stuck to the adhesive on the clamping jaw 10.

[0064] As another example, Figure 7 As shown, the first pressing unit 350 includes a first pressing member 351 arranged along the second direction, and the first pressing member 351 can be a strip or a plurality of pressure pins arranged at intervals. Further, in order to avoid crushing the solder strip, the first pressing member 351 can be arranged in a form of flexible contact with the solder strip. The solder strip handling assembly 300 also includes a second driving mechanism, and the second driving mechanism includes a second power actuator and a second connecting driving member 352 connected to the second power actuator. The second connecting driving member 352 simultaneously drives the first pressing members 351 in all the first pressing units 350 to rise or fall at the same time. Among them, the second power actuator can also be a cylinder or a motor, and the structure of the second connecting driving member 352 can also be diversified, as long as it can achieve the simultaneous driving of the first pressing members 351 in all the first pressing units 350 to rise or fall at the same time. Similarly, since one power actuator can simultaneously drive all the first pressing units 350 in the solder strip handling assembly 300 to simultaneously press down all the solder strips before the clamp 10 releases the solder strip, the action consistency is improved, and the structure is simple.

[0065] As another example, Figure 1As shown, the solder strip processing module also includes a plurality of solder strip cutting assemblies 400 arranged along the first direction, the transfer table assembly 200 includes a plurality of workbenches 210 arranged in sequence along the first direction, and the plurality of solder strip cutting assemblies 400 are arranged between two adjacent workbenches 210 and one of the solder strip cutting assemblies 400 is arranged at the end of the transfer table assembly 200. The end of the transfer table assembly 200 here refers to a position close to the solder strip feeding assembly 500, so that the solder strip of the required length pulled out from the solder strip feeding assembly 500 is cut off and no longer connected to the solder strip feeding assembly 500. The solder strip released from the solder strip feeding assembly 500 is cut into multiple sections by the solder strip cutting assembly 400 at the same time, and the number of the multiple sections is the same as the number of battery cells in a row of battery cells, that is, the solder strip of the required number of battery cells in at least one row is cut at one time, thereby facilitating the subsequent solder strip handling assembly 300 to clamp the solder strip and arrange it on the carrying module 100. Among them, the structure of the solder strip cutting assembly 400 can be a conventional structure in the prior art, mainly including an upper cutting knife, a lower cutting knife and a driving part for driving the cutting knife. The solder strip cutting assembly 400 can cut multiple solder strips at a time. Since the structure of the solder strip cutting assembly 400 is not the focus of protection of this patent, it will not be repeated here.

[0066] As another embodiment, the solder tape processing module also includes a solder tape feeding assembly 500 and a solder tape traction assembly 220. The solder tape feeding assembly 500 and the transfer table assembly 200 are arranged in sequence along a first direction. The solder tape feeding assembly 500 includes multiple solder tape rolls for providing multiple solder tapes, preferably, released along the first direction; wherein the solder tape traction assembly 220 includes a traction drive mechanism and multiple traction clamps connected to the traction drive mechanism, one traction clamp tractions one solder tape, and multiple traction clamps are arranged side by side in sequence along a second direction and are located above the transfer table assembly 200. The traction drive mechanism drives the multiple traction clamps to move back and forth between the solder tape feeding assembly 500 and the tail end of the transfer table assembly 200, and the tail end of the transfer table assembly 200 is the end away from the solder tape feeding assembly 500. The solder tape traction assembly 220 is used to pull out the multiple solder tapes released by the solder tape feeding assembly 500 along the first direction to the tail end close to the transfer table assembly 200, and after fixing the pulled solder tape on the transfer table assembly 200, it is convenient for the solder tape cutting assembly 400 to simultaneously cut the multiple solder tapes, and the solder tape traction assembly 220 can return to the solder tape feeding assembly 500 to pull the next solder tape. Among them, the traction clamp generally includes an upper clamp and a lower clamp for clamping the solder tape from the upper and lower sides of the solder tape, and the traction drive mechanism can be a cylinder or a motor. In order to fix the solder tape on the transfer table assembly 200, a fixing mechanism can be set on the workbench 210, or the solder tape can be fixed in the form of a pressing mechanism, so as to facilitate the solder tape cutting and avoid the position of the solder tape from being offset when the solder tape conveying assembly 300 takes the solder tape.

[0067] As another embodiment, the transfer table assembly 200 further includes a separation and positioning mechanism, which is used by the welding strip cutting assembly 400 to separate the multiple workbenches 210 at a desired distance after the welding strip is cut. The specific structure of the separation and positioning mechanism can be in various forms, such as the spacing limit mechanism disclosed in patent CN218135343U, as long as it can separate the cut welding strips at a desired distance, and the desired distance is the distance between adjacent welding strips in the battery assembly. Since the specific structure of the separation and positioning mechanism is not the focus of this patent, it will not be described here.

[0068] As another embodiment, the bearing module 100 includes a feed conveyor belt 120, a bearing mechanism and a discharge conveyor belt 130, the bearing mechanism includes a bearing member 110 and / or a movable suction cup assembly 140, and the input end and the output end of the bearing mechanism are respectively connected to the output end of the feed conveyor belt 120 and the input end of the discharge conveyor belt 130. Specifically, the bearing module 100 can be a non-movable bearing module 100, in which case it can only include the bearing member 110; it can also be a movable bearing module 100, in which case it can include both the bearing member 110 and the movable suction cup assembly 140, or only include the movable suction cup assembly 140. Among them, as Figure 8 As shown, the feed conveyor belt 120 and the discharge conveyor belt 130 each include two conveyor belt lines spaced a certain distance apart, and at least part of the bearing mechanism is located between the two conveyor belts. The feed conveyor belt 120 is used to transfer the substrate from the previous station to the station where the solder strip arrangement device is located for solder strip arrangement, and the discharge conveyor belt 130 is used to transport the substrate with solder strips arranged from the solder strip arrangement station to the next station. Specifically, one of the bearing mechanism or the feed conveyor belt 120 can be raised or lowered, so that the substrate and battery cells on the feed conveyor belt 120 can be transferred to the bearing mechanism; one of the bearing mechanism or the discharge conveyor belt 130 can be raised or lowered, so that the substrate on the bearing mechanism can be transferred to the discharge conveyor belt 130.

[0069] Considering that the solder tape transport assembly 300 can transport the required number of solder tapes for at least one row of battery cells to the carrier module 100 at one time, during the arrangement of the solder tapes, the carrier mechanism can be non-mobile. At this time, the carrier mechanism can include a plurality of carriers 110, and the plurality of carriers 110 are arranged at intervals along the second direction, and each carrier 110 is in the shape of a long strip, and the extension direction is the first direction.

[0070] Of course, based on some requirements, during the process of ribbon arrangement, the carrying mechanism can also be non-movable. For example, when the ribbon arrangement device includes the visual positioning mechanism and the position adjustment mechanism described below and is located before the ribbon arrangement station, the carrying mechanism can be set to be movable. For example, the carrying mechanism includes both the carrying member 110 and the movable suction cup assembly 140 as an example. Figure 8 As shown, at this time, the carrier 110 and the movable suction cup assembly 140 are staggered in the second direction. Among them, the movable suction cup assembly 140 includes a slide rail extending along the first direction, a suction cup driving member (such as a motor or a cylinder) and a suction cup mechanism connected to the slide rail and driven by the suction cup driving member to reciprocate along the slide rail. As one of the specific working processes, the feed conveyor belt 120 conveys the substrate to the station where the visual positioning mechanism and the position adjustment mechanism are located, and then the feed conveyor belt 120 descends, and the substrate is placed on the suction cup mechanism that has been moved to the position in advance, and then the suction cup mechanism moves along the slide rail to the welding strip arrangement station, and the substrate is transferred to the carrier 110 (such as a carrier plate) fixedly set at the welding strip arrangement station, and the suction cup mechanism returns to the station where the visual positioning mechanism and the position adjustment mechanism are located to receive the next substrate, and at the same time, the substrate located on the carrier 110 is arranged with welding strips. After the welding strip arrangement is completed, the discharge conveyor belt 130 rises, catches the substrate with the arranged welding strips and transports it to the next station. This makes it possible to visually locate and correct the position of the next group of substrates while arranging the solder strips, helping to improve production capacity.

[0071] As another example, Figure 1 As shown, the solder strip arrangement device further includes a visual positioning mechanism 600 and a position adjustment mechanism (not marked in the figure), the visual positioning mechanism 600 and the position adjustment mechanism are located at the solder strip arrangement station where the carrier module 100 is located or at the previous station of the carrier module 100; the position adjustment mechanism adjusts the position of the substrate according to the position data of the substrate obtained by the visual positioning mechanism 600. By setting the visual positioning mechanism 600 and the position adjustment mechanism, the position of the substrate and the battery cell can be adjusted before the solder strip is arranged, so that the position of the solder strip on the battery cell is more accurate.

[0072] Specifically, the visual positioning mechanism 600 can be a CCD camera, and considering the large size of the substrate, four CCD cameras can be arranged around the carrier module; the position adjustment mechanism can be a conventional structure in the prior art, for example, four alignment components arranged around the two long sides of the carrier module 100. When the position adjustment is performed, the four alignment components simultaneously push the substrate from both sides of the second direction of the substrate for position adjustment. More specifically, the alignment component includes an alignment drive (motor or cylinder) and a driving wheel connected to the alignment drive. Among them, when the visual positioning mechanism 600 and the position adjustment mechanism are both located at the welding strip arrangement station, the space occupied by the equipment can be saved. At this time, the visual positioning mechanism 600 is arranged above the carrier module 100, and the position adjustment mechanism is located around the long side of the carrier module 100; when the visual positioning mechanism 600 and the position adjustment mechanism are located at the previous station of the carrier module 100, the visual positioning mechanism 600 and the position adjustment mechanism are arranged when the substrate passes through the station, the visual positioning mechanism 600 is located above the substrate, and the position adjustment mechanism is located around the long side of the substrate.

[0073] This patent also proposes a solder strip arrangement system, including the solder strip arrangement device described in any of the above embodiments, and transfer table assemblies 200 and solder strip handling assemblies are provided on both sides of the long side of the carrier module 100, so that two sets of transfer table assemblies 200 and solder strip handling assemblies can work simultaneously, thereby improving production capacity.

[0074] As another embodiment, in the above-mentioned solder strip arrangement system, the solder strip handling assembly on one side arranges the first part of the solder strip group, and the solder strip handling assembly on the other side arranges the second part of the solder strip group. The first part of the solder strip group and the second part of the solder strip group constitute all the solder strips required for a battery assembly. Thus, one solder strip arrangement station can complete the arrangement of the solder strips required for the entire battery assembly. Furthermore, in order to increase production capacity, the solder strip handling assemblies on both sides can also simultaneously arrange multiple solder strips required for at least two rows of battery cells onto the carrier module 100.

[0075] This patent also proposes a solder strip arrangement system, comprising two solder strip arrangement devices described in any of the above embodiments arranged along a first direction, wherein one solder strip arrangement device arranges a first portion of a solder strip group, and the other solder strip arrangement device arranges a second portion of a solder strip group, and the first portion of the solder strip group and the second portion of the solder strip group constitute all the solder strips required for a battery assembly. Setting the solder strip arrangement station at two stations can save space in the width direction.
