Description

Technical Field

[0001] The present application relates to the field of photovoltaic module production equipment, and more specifically to a busbar processing device and processing equipment. Background Art

[0002] During the production of solar cells, it is necessary to weld busbars to the long ribbons at the ends of the cell strings. A cell string is formed by a certain number of cell strings arranged according to the layout requirements of the photovoltaic module. A cell string is formed by a certain number of cell sheets connected in series via ribbons. Figure 1 The battery string 100 shown has three busbars 200 welded to the extended welding strips at each end. Because the busbars 200 are positioned outside the end cells 101 of the battery string 100 after welding, the area of ​​the battery string 100 where the busbars 200 are welded is relatively large, a problem that urgently needs to be addressed. Utility Model Content

[0003] In order to solve the above technical problems, the present application provides a busbar processing device, and its technical solution is as follows:

[0004] A busbar processing device is used to flip the busbar welded to the long welding strip at the end of the battery string upward to the upper side of the battery string. The busbar processing device includes a first base, a support platform, a flipping platform and a flipping drive mechanism, wherein:

[0005] The support platform is fixedly arranged on the first base and extends along the first horizontal direction;

[0006] The turning platform extends along a first horizontal direction and is rotatably arranged relative to the support platform, and the turning drive mechanism is configured to drive the turning platform to rotate vertically relative to the support platform;

[0007] When the turning platform is rotated away from the supporting platform to the supporting position, the bearing surface of the turning platform and the supporting surface of the supporting platform are located in the same horizontal plane, the supporting surface of the supporting platform is used to support the end of the battery string group, and the bearing surface of the turning platform is used to support the bus bar;

[0008] When the turning platform is rotated toward the supporting platform to the turning position, the bearing surface of the turning platform is located above the supporting surface of the supporting platform, and the busbar is turned to the upper side of the battery string group.

[0009] The busbar processing device of the present application can automatically flip the busbar located on the outside of the end battery cell of the battery string group toward the inside of the battery string group, thereby reducing the area of ​​the battery string group. Specifically, when it is necessary to perform a flipping operation on the busbar at the end of the battery string group, the flipping table is first rotated to the support position, so that the bearing surface of the flipping table and the supporting surface of the support table are located at the same horizontal plane; then, the first base is controlled to move closer to the end of the battery string group until the end of the battery string group is supported on the supporting surface of the support table, and the busbar at the end of the battery string group is supported on the bearing surface of the flipping table; finally, the flipping table is rotated toward the support table to the flipping position, and the busbar can be flipped to the upper side of the battery string group. It can be seen that through the cooperation of the support table and the flipping table, the busbar processing device of the present application can automatically flip the busbar at the end of the battery string group to the upper side of the battery string group, thereby reducing the area of ​​the battery string group.

[0010] In some embodiments, when the flip table is rotated to the flip position, the rotation angle of the flip table is 180°; or, when the flip table is rotated to the flip position, the rotation angle of the flip table is greater than 90° and less than 180°, and the bus bar processing device also includes a liftable pressure plate, which is used to press the bus bar rotated to the flip position down onto the battery string group.

[0011] By setting the turning table's rotation angle to 180°, the table can directly flip the busbar to the upper side of the battery string and parallel to the cells, facilitating the subsequent laying and lamination of the photovoltaic module backsheet. By setting the turning table's rotation angle to greater than 90° and less than 180°, and providing a pressure plate, the table first flips the busbar to a flip position above the battery string, and then the pressure plate presses the busbar down onto the battery string. This also allows the flipped busbar to be parallel to the cells, facilitating the subsequent laying and lamination of the photovoltaic module backsheet.

[0012] In some embodiments, the flipping drive mechanism includes a rotating shaft and a connecting rod assembly, wherein: the rotating shaft is rotatably mounted on the first base, one end of the connecting rod assembly is fixedly connected to the rotating shaft, and the other end of the connecting rod assembly is hinged on the flipping platform. When the rotating shaft rotates, the connecting rod assembly drives the flipping platform to rotate vertically relative to the support platform.

[0013] A turning drive mechanism with a simple structure is provided, which drives the connecting rod assembly to push the turning platform to rotate vertically relative to the supporting platform by controlling the rotation of the rotating shaft, thereby ensuring the rotation stability of the turning platform.

[0014] In some embodiments, the flip drive mechanism further includes a drive member disposed on the first base, the drive member being in transmission connection with the rotating shaft, and the drive member being configured to drive the rotating shaft to rotate; or, the flip drive mechanism further includes a rotating operating lever connected to the rotating shaft.

[0015] By providing a driving member connected to the rotating shaft, the rotating shaft can be driven to rotate automatically, thereby realizing automatic flipping of the flip table, improving the automation level of the present application. By providing a rotating operating lever on the rotating shaft, the rotating shaft can be driven to rotate by pushing and pulling the rotating operating lever, thereby realizing manual flipping of the flip table, reducing the equipment cost of the present application.

[0016] In some embodiments, the connecting rod assembly includes a crank connecting rod and an L-shaped connecting rod, wherein: the first end of the crank connecting rod is fixedly connected to the rotating shaft; the first end of the L-shaped connecting rod is hinged to the second end of the crank connecting rod, and the second end of the L-shaped connecting rod is hinged to the turning platform.

[0017] By using a crank connecting rod and an L-shaped connecting rod connected to each other as a connecting rod assembly, the rotational torque of the rotating shaft can be converted into a push-pull torque on the turning table, thereby realizing the turning drive of the turning table.

[0018] In some embodiments, the first base is further configured to be translatable toward or away from the battery string along a second horizontal direction, the second horizontal direction being perpendicular to the first horizontal direction.

[0019] By controlling the first base to translate toward or away from the battery string, the support surface of the support table can automatically move to the end of the battery string where the busbar flipping process is to be performed, and the bearing surface of the flipping table can automatically move to the position of the busbar at the end of the battery string. In addition, the end of the battery string that has completed the busbar flipping process can automatically separate from the support table.

[0020] In some embodiments, an adsorption component is provided on the support platform, and the adsorption component is a suction cup or an adsorption hole. The support platform adsorbs the end of the battery string group onto the support surface through the adsorption component.

[0021] The ends of the battery string group are adsorbed and fixed, preventing the ends of the battery string group from moving during the bus bar flipping process, thereby affecting the flipping effect.

[0022] In some embodiments, the bus bar processing device also includes a second base, a first pressure plate and a first driving mechanism, wherein: the second base is arranged above the first base; the first driving mechanism is arranged on the second base, the first pressure plate is connected to the movable part of the first driving mechanism, and the first pressure plate extends along the first horizontal direction; when the flip table is in the supporting position, the first driving mechanism is configured to drive the first pressure plate to move toward the supporting table so that the first edge of the first pressure plate extending along the first horizontal direction is close to the end edge of the battery string group; the first driving mechanism is also configured to drive the first pressure plate to move away from the support table after the flip table rotates toward the support table by a predetermined angle to avoid the flip table, and the predetermined angle is less than 180°.

[0023] By providing a first drive mechanism and a first pressure plate, before the flip table rotates toward the support table, the first edge of the first pressure plate is driven by the first drive mechanism to approach the end edge of the battery string group, thereby limiting the position of the extended welding ribbon on the end battery cell of the battery string group. In this way, after the flip table rotates toward the support table by a predetermined angle, the first edge of the first pressure plate can form a certain angle on the extended welding ribbon under the position limit of the first pressure plate, so that when the first pressure plate moves away from the support table and returns to its original position, the flip table continues to rotate to the flip position, and the extended welding ribbon can continue to bend around the angle, thereby preventing the extended welding ribbon from twisting during the flipping of the busbar, or even causing the welding ribbon to separate from the connection between the battery cell and the welding ribbon.

[0024] In some embodiments, the first pressure plate has a horizontal lower pressing surface and a first side surface, the first side surface is the side surface of the first pressure plate facing the flip table, and the lower pressing surface and the first side surface intersect to form a first edge; the lower pressing surface of the first pressure plate is used to approach or press the battery cells of the battery string group; when the flip table rotates toward the support table at a predetermined angle, the first side surface approaches the bus bar on the flip table or contacts the bus bar.

[0025] Before the turning table rotates toward the support table, when the first pressure plate moves into position toward the support table, the lower pressure surface of the first pressure plate approaches or presses the battery cells of the battery string group, so that the long welding strip can be better limited in the subsequent turning process. By rotating the turning table so that the bus bar approaches or contacts the first side surface of the first pressure plate, the folding angle on the long welding strip can be made as obvious as possible, which is conducive to the smooth bending of the long welding strip after the first pressure plate is withdrawn.

[0026] In some embodiments, the first side surface is an inclined surface, and an angle less than 90° is formed between the first side surface and the downward pressing surface; the predetermined angle is greater than or equal to 90° and less than 180°.

[0027] By setting the first side surface as a slope, the predetermined angle is greater than or equal to 90° and less than 180°, so that when the turning table is rotated toward the support table by a predetermined angle, a fold angle less than or equal to 90° can be formed on the long welding strip. This is more conducive to the bending of the long welding strip after the first pressure plate is withdrawn.

[0028] In some embodiments, downward-inclined guide waist holes are respectively provided on both side walls of the second base along the first horizontal direction; the first driving mechanism includes a first translation driving unit, a translation plate and a lifting plate, wherein: the first translation driving unit is arranged on the second base; the translation plate is slidably connected to the second base and is connected to the driving end of the first translation driving unit, and the first translation driving unit is configured to drive the translation plate to move along the second horizontal direction, and the second horizontal direction is perpendicular to the first horizontal direction; the lifting plate is slidably connected to the translation plate in the vertical direction, and guide wheels corresponding to the guide waist holes are installed on both sides of the lifting plate along the first horizontal direction, and the guide wheels are located in the corresponding guide waist holes and can slide along the guide waist holes; the first pressure plate is connected to the lower end of the lifting plate.

[0029] By providing downwardly inclined guide waist holes on both side walls of the second base along the first horizontal direction, and by configuring the first driving mechanism to include a first translation driving unit, a translation plate and a lifting plate. When the first translation driving unit drives the translation plate to move along the second horizontal direction, the lifting plate can drive the first pressure plate to tilt and lift toward or away from the support platform. Specifically, before the turning platform rotates toward the support platform, the first translation driving unit drives the translation plate to translate toward the support platform, and the first pressure plate is driven by the lifting plate to move obliquely downward toward the support platform until it approaches or presses against the battery cells (i.e., the end battery cells) of the battery string group, thereby avoiding the risk of scratching the battery cells. After the turning platform rotates toward the support platform by a predetermined angle, the first pressure plate moves obliquely upward to avoid the turning platform. During the oblique upward movement, the first pressure plate will not cause scratches to the end battery cells and the bus bars on the turning platform.

[0030] In some embodiments, the first base is configured to rotate in a horizontal plane so that the flip table is parallel to the end edge of the battery string group; the second base is configured to rotate in a horizontal plane so that the first pressure plate is parallel to the end edge of the battery string group.

[0031] The flip table and the first pressing plate are adjusted to be parallel to the end edges of the battery string group, which can prevent the flip table from colliding with the first pressing plate during the flipping process, and the flip table from colliding with the end battery cells, causing the battery cells to crack or break.

[0032] In some embodiments, the busbar processing device further includes a camera disposed above the first base, the camera being configured to photograph and locate the end of the battery string group, and the first base and the second base being configured to rotate in a horizontal plane based on the position information of the end of the battery string group.

[0033] By arranging a camera above the first base, the end edge of the battery string group can be positioned, so that the first base and the second base can be accurately adjusted in angle on the horizontal plane according to the position of the end edge of the battery string group, ultimately ensuring that the turning table and the first pressing plate are parallel to the end edge of the battery string group.

[0034] In some embodiments, the flip table includes a table body and a sliding plate, wherein the table body is rotatable relative to the support table, and the sliding plate is slidably connected to the table body along a first horizontal direction, and the sliding plate is used to support the bus bar; the bus bar processing device also includes a second pressure plate and a second driving mechanism, wherein: the second pressure plate is connected to the movable part of the second driving mechanism and is located above the sliding plate, and the second pressure plate extends along the first horizontal direction; when the flip table is in the supporting position, the second driving mechanism is configured to drive the second pressure plate to move toward the flip table to press the bus bar on the sliding plate, and is also configured to drive the second pressure plate to translate along the first horizontal direction to drive the pressed sliding plate to slide synchronously along the first horizontal direction, so that the pressed bus bar is misaligned in the first horizontal direction relative to the end of the battery string group.

[0035] Before the turning platform drives the busbar to turn toward the support platform, the second pressure plate and the sliding plate cooperate with each other to press the busbar and drive the busbar to move along the first horizontal direction, so that the busbar is misaligned in the first horizontal direction relative to the end of the battery string group. In this way, the extended welding strip on the busbar and the welding strip on the upper surface of the end battery cell are also misaligned. The final effect is that after the turning platform turns the busbar to the upper side of the battery string group, the extended welding strip will not be stacked on the welding strip on the upper surface of the end battery cell. This can prevent the battery string assembly from short-circuiting when it is powered on, and also avoid excessive stress at the welding strip stacking point when the battery string assembly is subsequently laminated, which may cause damage to the battery cell.

[0036] In some embodiments, a return spring is provided between the platform and the sliding plate, with both ends of the return spring connected to the platform and the sliding plate respectively, and the return spring can be telescopically deformed in a first horizontal direction.

[0037] When the second drive mechanism drives the second pressure plate to translate along the first horizontal direction, causing the sliding plate to slide synchronously along the first horizontal direction, the return spring is compressed and deforms. When the busbar is completely misaligned and the second drive mechanism drives the second pressure plate to rise and return to its original position, the return spring loses pressure and rebounds to its original position, thereby pushing the sliding plate to automatically slide and return to its original position along the first horizontal direction.

[0038] In some embodiments, the second driving mechanism includes a second translation driving unit and a lifting driving unit, wherein the lifting driving unit is connected to the driving end of the second translation driving unit, and the second pressure plate is connected to the driving end of the lifting driving unit; the lifting driving unit is configured to drive the second pressure plate to rise and fall, and the second translation driving unit is configured to drive the second pressure plate to translate along the first horizontal direction.

[0039] Through the coordinated driving of the second translation driving unit and the lifting driving unit, the second driving mechanism can drive the second pressing plate to move up and down in the vertical direction and to translate in the first horizontal direction.

[0040] The present application also provides a busbar processing device, which includes a component positioning device and a first set of busbar processing devices, wherein:

[0041] The component positioning device is configured to fix the battery string group, and at least one bus bar is welded to the extended welding strip at the first end portion of the battery string group;

[0042] The first set of busbar processing devices is disposed on the first side of the assembly positioning device, and includes at least one busbar processing device as described above, wherein each busbar processing device is configured to flip a busbar at the first end of the battery string.

[0043] After the assembly positioning device secures the battery string, the extended solder strip at the first end of the battery string and the busbar thereon are located on the first side of the assembly positioning device. This allows the first set of busbar handling devices located on the first side of the assembly positioning device to flip the busbars on the extended solder strip at the first end of the battery string, thereby flipping the busbars to the upper side of the battery string and reducing the area of ​​the battery string.

[0044] In some embodiments, the component positioning device includes a carrying mechanism and a picking mechanism, wherein: the carrying mechanism is used to carry the battery string group, the picking mechanism is located above the carrying mechanism, and the picking mechanism is configured to pick up the battery string group from the carrying mechanism, and lift and position the picked battery string group to a predetermined height; the picking mechanism is also configured to place the battery string group that has completed the bus bar flipping process back onto the carrying mechanism.

[0045] When the busbar needs to be flipped, the pickup mechanism first picks up the battery string from the supporting mechanism and lifts and positions the picked-up battery string to a predetermined height, so that the first end of the battery string is suspended. In this way, when the first set of busbar handling devices located on the first side of the assembly positioning device moves toward the first end of the battery string, the first end of the battery string and the busbar thereon can be supported on the support platform and flipping platform of the busbar handling devices, respectively, allowing the busbar handling devices to smoothly perform the busbar flipping operation.

[0046] In some embodiments, at least one bus bar is welded to the extended welding strip at the second end of the battery string group, and the picking mechanism is further configured to rotate the battery string group to rotate the bus bar at the second end of the battery string group to the first group of bus bar processing devices, and each bus bar processing device in the first group of bus bar processing devices is further configured to flip a bus bar at the second end of the battery string group.

[0047] Because the pick-up mechanism can rotate the battery string, after the first set of busbar handling devices located on the first side of the assembly positioning device completes the flipping operation on the busbar at the first end of the battery string, the pick-up mechanism can rotate the battery string 180°, thereby rotating the busbar at the second end of the battery string to the first side of the assembly positioning device, allowing the first set of busbar handling devices to complete the flipping operation on the busbar at the second end of the battery string. In other words, by only providing the busbar handling device on one side of the assembly positioning device, the flipping operation of the busbars at both ends of the battery string can be completed sequentially, thereby saving equipment costs.

[0048] In some embodiments, the bus bar processing equipment further includes a second group of bus bar processing devices arranged on a second side of the component positioning device, and at least one bus bar is welded to the extended welding strip at the second end of the battery string group; the second group of bus bar processing devices includes at least one bus bar processing device described in any one of the above items, wherein each bus bar processing device is configured to flip the bus bar at the second end of the battery string group.

[0049] By arranging a second set of bus bar processing devices on the second side of the component positioning device, the first set of bus bar processing devices and the second set of bus bar processing devices can simultaneously perform flipping operations on the bus bars at the first and second ends of the battery string group, thereby improving the bus bar flipping efficiency.

[0075] In order to make the above-mentioned purposes, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0076] As mentioned in the background art, since the busbars are located outside the end battery cells of the battery string after being welded, the area of ​​the battery string with the busbars welded thereto is relatively large.

[0077] In order to solve this problem, the present application provides a busbar processing device, which is used to flip the busbar on the long welding strip welded on the end of the battery string group (i.e., the end battery cell of the battery string group) upward to the upper side of the battery string group, thereby reducing the area of ​​the battery string group.

[0078] Figure 2 FIG. 1 shows two end battery cells 101 of a battery string after the busbars are welded. Figure 2 As shown, the busbar 200 is located outside the end battery cell 101. Figure 3 As shown, after being flipped by the busbar processing device of the present application, the busbar 200 is flipped upward to the upper side of the end battery cell 101 .

[0079] It should be noted that "extended solder strip" refers to the portion of the solder strip welded and / or bonded to the end battery cell 101 that extends outward from the end battery cell 101. The extended solder strip can be formed by the solder strip welded and / or bonded to the upper surface of the end battery cell 101 extending outward, or by the solder strip welded and / or bonded to the lower surface of the end battery cell 101 extending outward. Figure 2 Taking the two end battery cells 101 shown as an example, the end of the welding strip 300 welded and / or bonded to the upper surface of the end battery cell 101 extends outward from the end battery cell 101, forming an extended welding strip 301; the end of the welding strip welded and / or bonded to the lower surface of the end battery cell 101 extends outward from the end battery cell 101, forming an extended welding strip 301; the bus bar 200 is welded to the extended welding strips of the two end battery cells 101.

[0080] like Figures 4 to 6 As shown, the busbar processing device 10 in the embodiment of the present application includes a first base 1, a support platform 2, a turning platform 3 and a turning drive mechanism 4, wherein:

[0081] The support platform 2 is fixedly disposed on the first base 1 and extends along a first horizontal direction (eg, X direction).

[0082] The turning platform 3 extends along the first horizontal direction and is rotatable relative to the supporting platform 2 . The turning drive mechanism 4 is configured to drive the turning platform 3 to rotate vertically relative to the supporting platform 2 .

[0083] When the flip table 3 rotates away from the support table 2 to the supporting position, the supporting surface of the flip table 3 and the supporting surface of the support table 2 are located on the same horizontal plane, wherein the supporting surface of the support table 2 is used to support the end of the battery string group (that is, the end of the end battery cell 101), and the supporting surface of the flip table 3 is used to support the bus bar 200.

[0084] When the turning platform 3 rotates toward the supporting platform 2 to the turning position, the supporting surface of the turning platform 3 is located above the supporting surface of the supporting platform 2, and the busbar 200 is turned to the upper side of the battery string group.

[0085] The optional flipping process of the busbar at the end of the battery string by the busbar processing device 10 in the embodiment of the present application is as follows:

[0086] First, the turning drive mechanism 4 rotates the turning table 3 to the supporting position, so that the bearing surface of the turning table 3 and the supporting surface of the supporting table 2 are located at the same horizontal plane.

[0087] Then, if Figure 4 As shown, the busbar processing device 10 is controlled to translate toward the battery string group, or the battery string group is controlled to translate toward the busbar processing device 10, until the end of the battery string group (i.e., the end of the end battery cell 101) is supported on the support surface of the support table 2, and the busbar 200 at the end of the battery string group is supported on the bearing surface of the flip table 3.

[0088] Next, the turning drive mechanism 4 drives the turning platform 3 to rotate toward the support platform 2 to the turning position, so that the bus bar 200 can be turned to the upper side of the battery string group.

[0089] It can be seen that, through the cooperation of the support platform 2 and the flipping platform 3, the busbar processing device 10 of the embodiment of the present application can automatically flip the busbar at the end of the battery string group to the upper side of the battery string group, thereby reducing the area of ​​the battery string group.

[0090] Figures 4 to 6 In the embodiment shown, the support platform 2 is fixedly mounted on the first base 1, that is, the support platform 2 and the first base 1 are a split structure. In other embodiments, the support platform 2 can also be integrally formed on the first base 1, that is, the support platform 2 and the first base 1 are an integrated structure.

[0091] The turning platform 3 can be rotatably connected to the supporting platform 2 via a rotating connection member, and the turning platform 3 can also be rotatably connected to the first base 1 or a mounting frame provided on the first base 1 via a rotating connection member. The rotating connection member can be a hinge, a hinge, etc.

[0092] like Figures 4 to 6In the illustrated embodiment, when the turning platform 3 is rotated to the turning position, the turning platform 3 rotates 180 degrees. In other words, simply by turning itself, the turning platform 3 can directly and completely retract the busbar 200 to the upper side of the battery string group, so that the busbar 200 is close to and parallel to the upper surface of the battery string group, preventing the busbar 200 from tilting upward.

[0093] In other embodiments, the busbar processing device further includes a liftable pressure plate. When the turning platform 3 is rotated to the turning position, the turning platform 3 rotates at an angle greater than 90° and less than 180°, for example, the turning angle of the turning platform 3 is 95°, 100°, 120°, 135°, etc.

[0094] When the turning table 3 drives the bus bar 200 to rotate to the turning position, the turning table 3 rotates away from the support table 2 and returns to its original position. The pressure plate further presses the bus bar rotated to the turning position onto the battery string group, so that the bus bar 200 is close to the upper surface of the battery string group and parallel to the upper surface of the battery string group, preventing the bus bar 200 from tilting upward.

[0095] like Figures 4 to 6 As shown, optionally, the flipping drive mechanism 4 includes a rotating shaft 41 and a connecting rod assembly, wherein: the rotating shaft 41 is rotatably mounted on the first base 1, one end of the connecting rod assembly is fixedly connected to the rotating shaft 41, and the other end of the connecting rod assembly is hinged on the flipping table 3. When the rotating shaft 41 rotates, the connecting rod assembly drives the flipping table 3 to rotate vertically relative to the support platform 2.

[0096] In order to further improve the flipping stability of the flipping platform 3 and prevent the flipping platform 3 from moving or tilting during the flipping process, optionally, the connecting rod assembly is set to two groups. When the rotating shaft 41 rotates, the two groups of connecting rod assemblies drive the flipping platform 3 from two different positions, so that the flipping platform 3 rotates vertically relative to the support platform 2.

[0097] like Figure 4 As shown, the flip drive mechanism 4 optionally further includes a rotation operating lever 42 connected to the rotating shaft 41. By manually pushing and pulling the rotation operating lever 42, the rotating shaft 41 can be driven to automatically rotate, thereby achieving manual flipping of the flip table 3, reducing the equipment cost of the busbar processing device in the embodiment of the present application.

[0098] Of course, the flip drive mechanism 4 may further include a drive member disposed on the first base 1, the drive member being in transmission connection with the rotating shaft 41. The drive member is configured to drive the rotating shaft 41 to rotate, thereby achieving automatic flipping of the flip table 3 and improving the automation level of the busbar processing device of the present application. The drive member may be, for example, a drive motor, which is in transmission connection with the rotating shaft 41 via gears or belts.

[0099] like Figures 4 to 6As shown, the connecting rod assembly optionally includes a crank connecting rod 43 and an L-shaped connecting rod 44, wherein the first end of the crank connecting rod 43 is fixedly connected to the rotating shaft 41. The first end of the L-shaped connecting rod 44 is hinged to the second end of the crank connecting rod 43, and the second end of the L-shaped connecting rod 44 is hinged to the turning platform 3. When the rotating shaft 41 rotates, the crank connecting rod 43 rotates synchronously. When the crank connecting rod 43 rotates, it drives the second end of the L-shaped connecting rod 44 to push up or pull down the turning platform 3, thereby realizing the turning drive of the turning platform 3.

[0100] That is, by using the interconnected crank connecting rod 43 and the L-shaped connecting rod 44 as a connecting rod assembly, the rotational torque of the rotating shaft 41 can be converted into a push-pull torque on the turning table 3 to achieve turning drive of the turning table 3.

[0101] Of course, the turning drive mechanism 4 may also adopt existing drive mechanisms of other structures, as long as it can drive the turning table 3 to rotate vertically relative to the supporting table 2 .

[0102] Optionally, the first base 1 is further configured to be capable of translationally moving toward or away from the battery string group along a second horizontal direction (such as the Y direction), where the second horizontal direction is perpendicular to the first horizontal direction.

[0103] By controlling the first base 1 to translate toward or away from the battery string, the end of the battery string to be subjected to busbar flipping can automatically reach the support surface of the support table 2, and the busbar at the end of the battery string can automatically reach the support surface of the flipping table 3. In addition, the end of the battery string that has completed the busbar flipping process can automatically leave the support table 2.

[0104] For example, the first base 1 can be placed on a translation drive device, which drives the first base 1 to translate along the second horizontal direction toward or away from the battery string group. The translation drive device is, for example, a slide driven by a cylinder module or a screw module, and the first base 1 is mounted on the slide.

[0105] Optionally, an adsorption component is also provided on the support platform 2. The adsorption component can be, for example, a suction cup or an adsorption hole. The support platform 2 adsorbs the end of the battery string group on the support surface through the adsorption component, thereby achieving adsorption and fixation of the end of the battery string group, preventing the end of the battery string group from moving during the bus bar flipping process, affecting the flipping effect of the bus bar.

[0106] As described above, in some embodiments, the extended ribbon is the portion of the ribbon welded to the top surface of the end cell that extends outward from the end cell. That is, the extended ribbon and the ribbon on the top surface of the end cell are different portions of the same ribbon. In this case, when the turning table 3 drives the extended ribbon and the busbar to turn toward the support table 2, the extended ribbon will pull on the ribbon on the top surface of the end cell, potentially causing the ribbon on the top surface of the end cell to detach from the end cell, resulting in desoldering.

[0107] To solve this problem, Figures 4 to 6 As shown, optionally, the busbar processing device in the embodiment of the present application further includes a second base 5, a first pressure plate 6, and a first drive mechanism 7, wherein: the second base 5 is disposed above the first base 1. The first drive mechanism 7 is disposed on the second base 5, and the first pressure plate 6 is connected to the movable component of the first drive mechanism 7, and the first pressure plate 6 extends along a first horizontal direction (e.g., the X direction). When the flip table 3 is in the supporting position, the first drive mechanism 7 is configured to drive the first pressure plate 6 to move toward the support table 2 so that the first edge of the first pressure plate 6 extending along the first horizontal direction is close to the end edge of the battery string (i.e., the edge of the end battery cell). The first drive mechanism 7 is also configured to drive the first pressure plate 6 to move away from the support table 2 to avoid the flip table 3 after the flip table 3 rotates toward the support table 2 by a predetermined angle, wherein the predetermined angle is any angle less than 180°, for example, the predetermined angle is 60°, 90°, 120°, 135°, 150°, etc.

[0108] In order to enable those skilled in the art to more clearly understand the working process of the busbar processing device in the embodiment of the present application, the following will be combined with Figure 10 , the process of the support platform 2, the turning platform 3 and the first pressing plate 6 cooperating with each other to implement the busbar turning is described in detail.

[0109] like Figure 10 As shown in (a), first, the flip table 3 is driven to the support position by the flip drive mechanism 4, so that the supporting surface of the flip table 3 and the supporting surface of the support table 2 are located in the same horizontal plane. Then, by controlling the busbar processing device 10 to translate toward the battery string group, or controlling the battery string group to move toward the busbar processing device 10, the end of the battery string group (i.e., the end of the end battery cell 101) is supported on the supporting surface of the support table 2, and the busbar 200 at the end of the battery string group is supported on the supporting surface of the flip table 3. Subsequently, the first drive mechanism 7 drives the first pressure plate 6 to move toward the support table 2, so that the first edge of the first pressure plate 6 is close to the end edge of the end battery cell 101, thereby achieving the limitation of the root of the long welding strip.

[0110] like Figure 10As shown in (b) of FIG. 3 , the turning drive mechanism 4 drives the turning table 3 to rotate toward the supporting table 2. During the rotation, since the root of the extended welding ribbon has been positioned and fixed by the first pressing plate 6, the extended welding ribbon will bend around the portion supported by the first pressing plate 6.

[0111] like Figure 10 As shown in (c), after the turning table 3 rotates toward the support table 2 by a predetermined angle, the first drive mechanism 7 drives the first pressure plate 6 to move away from the support table 2 and return to its original position. At this point, since the extended solder strip 301 has formed an angle a with the end battery cell, the extended solder strip 301 can continue to bend around the angle as the turning table 3 continues to rotate toward the support table 2, thereby preventing the extended solder strip from twisting during the busbar flipping process, or even causing the solder strip to detach from the battery cell connection.

[0112] That is to say, after the flip table 3 rotates toward the support table 2 by a predetermined angle, the rotation of the flip table 3 can be avoided by controlling the first pressure plate 6 to move away from the support table 2 and return to its original position, so that the flip table 3 can continue to flip toward the support table 2, and the long solder strip will not be twisted or even the connection between the solder strip and the battery cell will not be separated because the first pressure plate 6 stops limiting the long solder strip.

[0113] like Figure 10 As shown in (d) in FIG. 1 , after the turning stage 3 completes the 180° turning, the bus bar 200 is turned over to the upper side of the end battery cell 101 .

[0114] It can be seen that through the cooperation of the support table 2, the turning table 3 and the first pressure plate 6, the busbar processing device in the embodiment of the present application can effectively prevent the long welding strip from being twisted, and prevent the welding strip on the upper surface of the end battery cell from being pulled and detached from the end battery cell 101, while ensuring that the busbar 200 is turned to the upper side of the end battery cell 101.

[0115] like Figure 6 As shown, the first pressing plate 6 optionally has a horizontal lower pressing surface 61 and a first side surface 62. The first side surface 62 is the side surface of the first pressing plate 6 facing the flip table 3. The lower pressing surface 61 and the first side surface 62 intersect to form a first edge. The lower pressing surface 61 of the first pressing plate 6 is used to approach or press the battery cells (i.e., the end battery cells 101) of the battery string. When the flip table 3 rotates toward the support table 2 by a predetermined angle, the first side surface 62 approaches or contacts the busbar on the flip table 3.

[0116] Before the flip table 3 rotates toward the support table 2, the lower pressing surface 61 of the first pressure plate 6 approaches or presses the battery cells of the battery string group, so that the extended welding strip can be better limited in the subsequent flipping process. By rotating the flip table 3 so that the bus bar approaches or contacts the first side surface 62 of the first pressure plate 6, the folding angle on the extended welding strip can be made as obvious as possible, which is conducive to the smooth bending of the extended welding strip after the first pressure plate 6 is withdrawn.

[0117] Optionally, the first side surface 62 is an inclined surface, and an angle less than 90° is formed between the first side surface 62 and the pressing surface 61. The predetermined angle is greater than or equal to 90° and less than 180°.

[0118] Continue to refer Figure 10 By setting the first side surface 62 as a slope, the predetermined angle is greater than or equal to 90° and less than 180°, so that when the turning table 3 is rotated toward the support table 2 by a predetermined angle, a fold angle less than or equal to 90° can be formed on the long welding strip. This is more conducive to the bending of the long welding strip after the first pressing plate 6 is withdrawn.

[0119] like Figures 8 and 9 As shown, optionally, downwardly inclined guide waist holes 51 are respectively provided on the side walls of the second base 5 along the first horizontal direction (such as the X direction). The first driving mechanism 7 includes a first translation driving unit 71, a translation plate 72 and a lifting plate 73, wherein: the first translation driving unit 71 is arranged on the second base 5. The translation plate 72 is slidably connected to the second base 5 and is connected to the driving end of the first translation driving unit 71. The first translation driving unit 71 is configured to drive the translation plate 72 to move along the second horizontal direction (such as the Y direction), and the second horizontal direction is perpendicular to the first horizontal direction. The lifting plate 73 is slidably connected to the translation plate 72 in the vertical direction. Guide wheels 74 corresponding to the guide waist holes are installed on both sides of the lifting plate 73 along the first horizontal direction. The guide wheels 74 are located in the corresponding guide waist holes 51 and can slide along the guide waist holes 51. The first pressing plate 6 is connected to the lower end of the lifting plate 73.

[0120] When the first translation drive unit 71 drives the translation plate 72 to move along the second horizontal direction, the lifting plate 73 can drive the first pressure plate 6 to move up and down obliquely toward or away from the support platform 2. Specifically: before the flip table 3 rotates toward the support platform 2, the first translation drive unit 71 drives the translation plate 72 to translate toward the support platform 2, and the first pressure plate 6 is driven by the lifting plate 73 to move obliquely downward toward the support platform 2, thereby approaching or pressing against the battery cells (i.e., the end battery cells) of the battery string group, avoiding the risk of scratching the battery cells. After the flip table 3 rotates toward the support platform 2 by a predetermined angle, the first translation drive unit 71 drives the translation plate 72 to translate away from the support platform 2, and the first pressure plate 6 moves obliquely upward to avoid the flip table 3. During the oblique upward movement, the first pressure plate 6 will not cause scratches to the end battery cells and the bus bars on the flip table 3.

[0121] Optionally, the second base 5 is provided with a first slide rail extending along the second horizontal direction, and the translation plate 72 is slidably connected to the first slide rail via a slider. The translation plate 72 is provided with a second slide rail extending along the vertical direction, and the lifting plate 73 is slidably connected to the second slide rail via a slider.

[0122] The first translation driving unit 71 can adopt various existing linear driving modules that can drive the translation plate 72 to translate along the second horizontal direction, such as a cylinder, a screw motor, etc.

[0123] Optionally, the first base 1 is configured to rotate in a horizontal plane so that the flip table 3 is parallel to the end edge of the battery string group (i.e., the edge of the end battery cell 101). The second base 5 is configured to rotate in a horizontal plane so that the first pressure plate 6 is parallel to the end edge of the battery string group. The flip table 3 and the first pressure plate 6 are both adjusted to be parallel to the end edge of the battery string group to prevent the flip table 3 from colliding with the first pressure plate 7 during the flipping process, and the flip table 3 from colliding with the end battery cell, which may cause the battery cell to crack or break.

[0124] Optionally, the busbar processing device in the embodiment of the present application further includes a camera disposed above the first base 5. The camera is configured to photograph and locate the end of the battery string, thereby obtaining positional information of the end of the battery string (i.e., the edge of the end battery cell 101). The first base 1 and the second base 5 are both configured to rotate within a horizontal plane based on the positional information of the end of the battery string to achieve precise adjustment of their angles within the horizontal plane, ultimately ensuring that the flip table 3 and the first pressing plate 5 are parallel to the end edge of the battery string.

[0125] Continue to refer Figures 4 to 7 As shown, the flip table 3 optionally includes a table body 31 and a sliding plate 32, wherein the table body 31 is rotatably arranged relative to the support table 2. For example, the table body 31 is rotatably connected to the support table 2 via a hinge or a hinge, or the table body 31 is rotatably connected to the first base 1 or a mounting frame provided on the first base 1 via a hinge or a hinge. The sliding plate 32 is slidably connected to the table body 31 along a first horizontal direction (e.g., the X direction) and is used to support the bus bar 200.

[0126] The busbar processing device in the embodiment of the present application further includes a second pressing plate 8 and a second driving mechanism 9 , wherein: the second pressing plate 8 is connected to the movable part of the second driving mechanism 9 and is located above the sliding plate 32 , and the second pressing plate 8 extends along the first horizontal direction.

[0127] When the flip table 3 is in the supporting position, the second driving mechanism 9 is configured to drive the second pressing plate 8 to move toward the flip table 3, so that the second pressing plate 8 presses the bus bar 200 located on the sliding plate 32. Subsequently, the second driving mechanism 9 is further configured to drive the second pressing plate 8 to translate along the first horizontal direction, thereby driving the pressed sliding plate 32 to slide synchronously along the first horizontal direction, ultimately causing the pressed bus bar 200 to be misaligned in the first horizontal direction relative to the end of the battery string group.

[0128] Because the busbar 200 is misaligned in the first horizontal direction relative to the end of the battery string assembly before the turning table 3 flips it, the excess solder ribbon on the busbar and the solder ribbon on the upper surface of the end battery cell are also misaligned accordingly. This results in the busbar 200 not being stacked on the solder ribbon on the upper surface of the end battery cell when the turning table 3 flips it to the upper side of the battery string assembly, thereby preventing a short circuit when the battery string assembly is powered on and also preventing excessive stress at the solder ribbon stacking point, which could cause damage to the battery cells during subsequent lamination of the battery string assembly.

[0129] Figures 4 to 7 In the illustrated embodiment, the second driving mechanism 9 is mounted on the second base 5. In other embodiments, the second driving mechanism 9 may also be provided separately.

[0130] Optionally, a third slide rail extending along the first horizontal direction is provided on the platform 31 , and the sliding plate 32 is slidably connected to the third slide rail via a slider.

[0131] Optionally, a return spring is provided between the platform 31 and the sliding plate 32 , with both ends of the return spring connected to the platform 31 and the sliding plate 32 respectively, and the return spring can be telescopically deformed in the first horizontal direction.

[0132] When the second drive mechanism 9 drives the second pressure plate 8 to translate along the first horizontal direction, causing the sliding plate 32 to slide synchronously along the first horizontal direction, the return spring is compressed and undergoes expansion and contraction deformation. When the busbars are completely dislocated and the second drive mechanism 9 drives the second pressure plate 8 upward and back to its original position, the return spring loses pressure and rebounds, pushing the sliding plate 32 to slide and return along the first horizontal direction. In other words, the provision of the return spring achieves automatic return of the sliding plate 32.

[0133] like Figure 7 As shown, optionally, a plurality of (eg Figure 7The bottom of the sliding plate 32 is provided with a plurality of limit blocks 34 corresponding to the limit slots 33. Each limit block 34 is located in a corresponding limit slot 33 and can slide in the corresponding limit slot 33 along the first horizontal direction. This arrangement limits the sliding travel of the sliding plate 32 in the first horizontal direction, preventing the sliding plate 32 from moving too far in translation and causing the welding ribbon to be stretched, deformed, or torn.

[0134] In addition, the limiting groove 33 provides an installation space for the return spring. For example, the return spring is installed in the limiting groove 33, one end of the return spring is connected to a side wall of the limiting groove 33, and the other end of the return spring is connected to the limiting block 34.

[0135] like Figure 8 As shown, optionally, the second driving mechanism 9 includes a second translation driving unit 91 and a lifting driving unit 92, wherein the lifting driving unit 92 is connected to the driving end of the second translation driving unit 91, and the second pressing plate 8 is connected to the driving end of the lifting driving unit 9. The lifting driving unit 92 is configured to drive the second pressing plate 8 to move up and down, and the second translation driving unit 91 is configured to drive the second pressing plate 8 to translate along the first horizontal direction.

[0136] Through the coordinated driving of the second translation drive unit 91 and the lifting drive unit 92, the second drive mechanism 9 realizes the position adjustment of the second pressure plate 8 in the vertical direction and the first horizontal direction, so that the second pressure plate 8 can press the bus bar 200 located on the sliding plate 32, and drive the pressed sliding plate 32 to slide synchronously along the first horizontal direction, thereby realizing the dislocation of the bus bar 200 in the first horizontal direction.

[0137] The second translation driving unit 91 and the lifting driving unit 92 can both adopt existing linear driving modules of various structures, such as cylinders, screw motors, etc.

[0138] Based on the same application concept, the present application also provides a busbar processing device, which can perform a flipping operation on the busbar on the long welding strip at the end of the battery string group, thereby flipping the busbar to the upper side of the battery string group and reducing the area of ​​the battery string group.

[0139] Figure 11 FIG. 1 shows a busbar processing device in one embodiment of the present application. Figure 12 FIG. 1 shows a busbar processing device in another embodiment of the present application. Figures 11 to 12 As shown, the busbar processing device in the embodiment of the present application includes a component positioning device 20 and a first group of busbar processing devices, wherein:

[0140] The assembly positioning device 20 is configured to fix the battery string group, and at least one bus bar is welded to the extended welding strip at the first end portion of the battery string group.

[0141] The first group of bus bar processing devices is arranged on the first side (such as side A) of the component positioning device 20, and includes at least one bus bar processing device 10 provided in any of the above embodiments, wherein each bus bar processing device 10 is configured to flip a bus bar at the first end of the battery string group, thereby flipping the bus bar to the upper side of the battery string group.

[0142] The number of bus bar handling devices 10 included in the first group of bus bar handling devices can be equal to the number of bus bars at the first end of the battery string. In this way, each bus bar handling device 10 in the first group of bus bar handling devices can synchronously complete the flipping of all bus bars at the first end of the battery string, thereby improving flipping efficiency. For example, if there are three bus bars at the first end of the battery string, the first group of bus bar handling devices will include three bus bar handling devices 10 accordingly.

[0143] Of course, the number of bus bar processing devices 10 included in the first group of bus bar processing devices may also be less than the number of bus bars on the first end of the battery string group. In this case, the first group of bus bar processing devices needs to complete the flipping operation of the bus bar on the first end of the battery string group in multiple times.

[0144] like Figures 11 to 12 As shown, the assembly positioning device 20 optionally includes a carrying mechanism 21 and a picking mechanism 22, wherein the carrying mechanism 21 is used to carry the battery string group, and the picking mechanism 22 is located above the carrying mechanism 21. The picking mechanism 22 is configured to pick up the battery string group from the carrying mechanism 21 and lift and position the picked battery string group to a predetermined height. The picking mechanism 22 is also configured to return the battery string group, after the busbar flipping process has been completed, to the carrying mechanism 21.

[0145] When the busbar needs to be flipped, the picking mechanism 22 first picks up the battery string from the supporting mechanism 21, lifts the picked battery string, and positions it to a predetermined height, so that the first end of the battery string is suspended. In this way, when the first set of busbar handling devices located on the first side of the assembly positioning device moves toward the first end of the battery string, the first end of the battery string and the busbar thereon can be supported on the support platform 2 and flipping platform 3 of the busbar handling device 10, respectively, allowing the busbar handling device 10 to smoothly perform the busbar flipping operation.

[0146] Optionally, the carrying mechanism 21 is a conveyor belt, which can carry and transport the battery string group. A busbar flipping station is provided on the conveying path of the conveyor belt. The first group of busbar processing devices is located on the first side of the busbar flipping station, and the picking mechanism 22 is located above the busbar flipping station. When the conveyor belt transports the battery string group to the busbar flipping station, the picking mechanism 22 lifts the battery string group, and the first group of busbar processing devices completes the flipping operation of the busbar at the first end of the battery string group. The picking mechanism 22 puts the battery string group that has completed the busbar flipping back to the busbar flipping station, and the conveyor belt continues to transport the battery string group to the downstream processing station.

[0147] Of course, the carrying mechanism 21 can also be a carrying platform with only a carrying function, and the battery string group is carried to the carrying platform by the carrying device. After the battery string group undergoes the bus bar flipping operation, the carrying device then moves the battery string group away from the carrying platform.

[0148] The picking mechanism 22 may use a suction cup assembly driven by a lifting drive unit, which drives the suction cup assembly to rise and fall, thereby driving the suction cup assembly to suck and lift the battery string group from the supporting mechanism 21 and place the battery string group back on the supporting mechanism 21.

[0149] In some application scenarios, at least one bus bar is also welded to the extended welding strip at the second end of the battery string. In order to be able to perform a flipping operation on the bus bar at the second end of the battery string. Figure 11 As shown, optionally, the picking mechanism 22 is further configured to rotate the battery string group to rotate the bus bar at the second end of the battery string group to the first group of bus bar processing devices, and each bus bar processing device 10 in the first group of bus bar processing devices is further configured to flip a bus bar at the second end of the battery string group.

[0150] Because the pick-up mechanism 22 is capable of rotating the battery string, once the first set of busbar handling devices located on the first side (e.g., side A) of the assembly positioning device completes the flipping operation on the busbar at the first end of the battery string, the pick-up mechanism can rotate the battery string 180°, thereby rotating the busbar at the second end of the battery string to the first side of the assembly positioning device. The first set of busbar handling devices then completes the flipping operation on the busbar at the second end of the battery string. In other words, by only providing the busbar handling device on one side of the assembly positioning device 20, the flipping operation on the busbars at both ends of the battery string can be completed sequentially, thereby saving equipment costs.

[0151] like Figure 12As shown, in another embodiment, the busbar processing equipment of the present application further includes a second group of busbar processing devices arranged on the second side (such as side B) of the component positioning device 20, and at least one busbar is welded to the extended welding strip at the second end of the battery string group. The second group of busbar processing devices 10 includes at least one busbar processing device 10 provided by any of the above embodiments, wherein each busbar processing device 10 is configured to flip the busbar at the second end of the battery string group. By arranging the second group of busbar processing devices on the second side of the component positioning device 20, the first group of busbar processing devices and the second group of busbar processing devices can simultaneously perform the flipping operation on the busbars at the first end and the second end of the battery string group, thereby improving the busbar flipping efficiency.

[0152] Similarly, the number of bus bar processing devices 10 included in the second group of bus bar processing devices can be equal to the number of bus bars on the second end of the battery string group, or the number of bus bar processing devices 10 included in the second group of bus bar processing devices can be less than the number of bus bars on the second end of the battery string group.

[0153] The above description of the present application is sufficiently detailed and has certain particularities. Those skilled in the art should understand that the descriptions in the embodiments are merely exemplary, and that all changes made without departing from the true spirit and scope of the present application should fall within the scope of protection of the present application.

Furthermore, the embodiments mentioned in the present application are not limited to being implemented individually, and some embodiments can also be implemented in combination.
