[0034] like Figure 1-Figure 7 As shown, a riveting tool 20 according to an embodiment of the first aspect of the utility model comprises: a riveting nozzle 24 and a support member 21 .

[0035] The riveting nozzle 24 is disposed on the supporting member 21 .

[0036] A positioning portion is provided on the support member 21 , and the positioning portion is suitable for positioning and cooperating with the heating plate 10 , and the distance between the positioning portion and the riveting nozzle 24 is adjustable.

[0037] It should be noted that in actual applications, CCS (Cells Contact System, integrated busbar) is a wiring harness board integrated product, which is usually composed of FPC (Flexible Printed Circuit, flexible circuit board), plastic structural parts, copper and aluminum bars, etc., and is connected into a whole through riveting process to achieve high-voltage series and parallel connection of battery cells, as well as battery temperature sampling and battery cell voltage sampling functions.

[0038] In the related art, integrated busbar assembly riveting equipment is used for riveting. The integrated busbar assembly riveting equipment includes a heating plate 10, a riveting tool 20 and other related parts. The heating plate 10 is provided with a plurality of through holes 11, which are arranged in a rectangular array, and the distance between any two adjacent through holes 11 is a fixed value, which is L1.

[0039] The riveting tool 20 includes a riveting nozzle 24 and a support 21, and the riveting nozzle 24 is arranged on the support 21. The support 21 is provided with a positioning portion, which is used to position and cooperate with the through hole 11 of the heating plate 10, thereby limiting the position of the riveting nozzle 24 in the horizontal direction (X, Y direction).

[0040] like Figure 7As shown, an X, Y coordinate system is set on the heating plate 10. For example, the first position a on the heating plate 10 is selected for riveting, and the positioning portion is positioned and matched with the through hole 11 of the heating plate 10, so that the center of the riveting nozzle 24 is at point a under the X, Y coordinates. Alternatively, the second position b on the heating plate 10 is selected for riveting, and the positioning portion is positioned and matched with the through hole 11 of the heating plate 10, so that the center of the riveting nozzle 24 is at point b under the X, Y coordinates. This embodiment is not listed one by one. Those skilled in the art can select any point on the heating plate 10 as the riveting position according to needs.

[0041] Based on this, the distance between the positioning portion and the riveting nozzle 24 of this embodiment is adjustable, thereby greatly improving the probability that the positioning portion can be positioned and matched with the heating plate 10, so that any point on the heating plate 10 can be used as a riveting position, avoiding the need to replace the heating plate 10 for a specific CCS structure, and helping to reduce production costs.

[0042] In detail, in the first embodiment, the riveting tool 20 includes a riveting nozzle 24 , a supporting member 21 and a movable member 22 .

[0043] The movable member 22 is provided with a first positioning portion 221 . The riveting nozzle 24 is fixedly connected to the supporting member 21 , and a movable member mounting portion is provided on the supporting member 21 . The movable member 22 can move in the movable member mounting portion to adjust the distance between the first positioning portion 221 and the riveting nozzle 24 .

[0044] In a specific embodiment, Figure 3-Figure 5 As shown, a hollow area 211 is provided on the support member 21, and the hollow area 211 may be stepped, and may include a first circular hollow area 2111 and a second circular hollow area 2112 arranged up and down. Among them, the diameter of the first circular hollow area 2111 is greater than the diameter of the second circular hollow area 2112. The movable member 22 is cylindrical, and the outer contour of the movable member 22 matches the outer contour of the first circular hollow area 2111. The movable member 22 can be inserted and matched with the first circular hollow area 2111, and the movable member 22 can rotate in the first circular hollow area 2111. A first long hole is provided on the movable member 22, and the first long hole is the above-mentioned first positioning portion 221. The first long hole runs through the movable member 22, and the first long hole may be straight, arc-shaped, L-shaped, ...

[0045] like Figure 7As shown, a first straight-line elongated hole is provided on the movable part 22. The first position a on the heating plate 10 is selected for riveting, the movable part 22 is rotated, and the position of the first elongated hole relative to the riveting nozzle 24 is adjusted so that at least one of the multiple through holes 11 corresponding to the projection area of ​​the movable part 22 on the heating plate 10 matches the first elongated hole. The fastener can pass through the first elongated hole and the through hole 11 in sequence to achieve positioning and matching between the first elongated hole and the through hole 11 of the heating plate 10, so that the center of the riveting nozzle 24 coincides with point a on the heating plate 10.

[0046] like Figure 7 As shown, the second position b on the heating plate 10 is selected for riveting, the movable member 22 rotates, and the position of the first elongated hole relative to the riveting nozzle 24 is adjusted, so that at least one of the multiple through holes 11 corresponding to the projection area of ​​the movable member 22 on the heating plate 10 matches the first elongated hole, and the fastener can pass through the first elongated hole and the through hole 11 in sequence to achieve the positioning and matching of the first elongated hole and the through hole 11 of the heating plate 10, so that the center of the riveting nozzle 24 coincides with point b on the heating plate 10. Among them, the extension direction of the first elongated hole at the second position b is substantially perpendicular to the extension direction of the first elongated hole at the first position a.

[0047] like Figure 7 As shown, the third position c on the heating plate 10 is selected for riveting, the movable member 22 rotates, and the position of the first elongated hole relative to the riveting nozzle 24 is adjusted, so that at least one of the multiple through holes 11 corresponding to the projection area of ​​the movable member 22 on the heating plate 10 matches the first elongated hole, and the fastener can pass through the first elongated hole and the through hole 11 in sequence to achieve positioning and matching between the first elongated hole and the through hole 11 of the heating plate 10, so that the center of the riveting nozzle 24 coincides with point c on the heating plate 10. Among them, the extension direction of the first elongated hole at the third position c is different from the extension direction of the first elongated hole at the first position a or the second position b.

[0048] In this way, the movable member 22 can rotate in the hollow area 211, and the movable member 22 is provided with a first long hole, which can be matched with one of the plurality of through holes 11, and then the distance between the fastener passing through the first long hole and the riveting nozzle 24 can be adjusted, so that the riveting position corresponding to any position in the heating plate 10 can be met, and the replacement of the heating plate 10 can be avoided, which helps to reduce production costs. In addition, the operation is convenient and simple, which helps to reduce the complexity of the equipment.

[0049] It should be noted that the first positioning portion 221 may be other structures besides the first elongated hole, such as a first protrusion. At least one of the plurality of through holes 11 corresponding to the projection area of ​​the movable member 22 on the heating plate 10 is inserted and matched with the first protrusion, so that the first protrusion is positioned and matched with the through hole 11 of the heating plate 10.

[0050] The movable member installation portion may be other structures besides the circular hollow area 211, such as a guide slot, which passes through the support member 21. The movable member 22 may slide along the guide slot, which is not limited in this embodiment.

[0051] Of course, the movable member 22 may not be circular, and correspondingly, the first circular hollow area 2111 may not be compatible with the movable member 22. It is only necessary that the movable member 22 can be disposed in the first circular hollow area 2111 and the movable member 22 can rotate in the first circular hollow area 2111.

[0052] Alternatively, if Figure 4 or Figure 5 As shown, the length of the first long hole is L2, L2 ≥ L1. This arrangement can make one of the more through holes 11 match the first long hole, ensuring the probability of positioning and matching the first long hole with the heating plate 10, and thus can meet the riveting position corresponding to any position in the heating plate 10, so as to change the position of the riveting tool in the plane relative to the heating plate by adjusting the through hole position matched by the positioning part.

[0053] Optionally, at least two movable members 22 are provided, and the movable members 22 are arranged around the riveting nozzle 24 at equal intervals.

[0054] Specifically, Figure 4 or Figure 5 As shown, two circular hollow areas 211 are provided on the support member 21, and the two hollow areas 211 are arranged around the riveting nozzle 24 at equal intervals, that is, the two hollow areas 211 are arranged symmetrically about the riveting nozzle 24. Two movable parts 22 are respectively provided in the two hollow areas 211, and the movable parts 22 can rotate in the hollow areas 211. Each movable part 22 is provided with a first long strip hole. By increasing the number of movable parts 22, the connection strength between the riveting tool 20 and the heating plate 10 is improved, which helps to stably set the riveting nozzle 24 at the desired position.

[0055] In the second embodiment, the riveting tool 20 includes a riveting nozzle 24 and a supporting member 21 .

[0056] The support member 21 is provided with a second positioning portion 213 . The support member 21 is movably connected to the riveting nozzle 24 . The support member 21 can rotate around the riveting nozzle 24 to adjust the distance between the second positioning portion 213 and the riveting nozzle 24 .

[0057] In a specific embodiment, Figure 6As shown, the support member 21 has a connecting hole 214, and the riveting nozzle 24 is sleeved on the support member 21 through the connecting hole 214, wherein a bearing is provided between the support member 21 and the riveting nozzle 24, and the support member 21 can freely rotate around the riveting nozzle 24. Two second elongated holes are provided on the support member 21, and the two second elongated holes are arranged around the riveting nozzle 24 at equal intervals. The second elongated hole is the second positioning portion 213 mentioned above.

[0058] like Figure 7 As shown, the fourth position d on the heating plate 10 is selected for riveting, the support member 21 is rotated, and the position of the second elongated hole relative to the riveting nozzle 24 is adjusted so that at least one of the multiple through holes 11 corresponding to the projection area of ​​the support member 21 on the heating plate 10 matches the second elongated hole, and the fastener can pass through the second elongated hole and the through hole 11 in sequence to achieve positioning and matching of the second elongated hole and the through hole 11 of the heating plate 10, so that the center of the riveting nozzle 24 coincides with point d on the heating plate 10.

[0059] like Figure 7 As shown, the fifth position e on the heating plate 10 is selected for riveting, the support member 21 is rotated, and the position of the second long hole relative to the riveting nozzle 24 is adjusted so that at least one of the multiple through holes 11 corresponding to the projection area of ​​the support member 21 on the heating plate 10 matches the second long hole, and the fastener can pass through the second long hole and the through hole 11 in sequence to achieve positioning and matching between the second long hole and the through hole 11 of the heating plate 10, so that the center of the riveting nozzle 24 coincides with the point e on the heating plate 10. Among them, the extension direction of the second long hole at the fourth position d is different from the extension direction of the second long hole at the fifth position e.

[0060] like Figure 7 As shown, the sixth position f on the heating plate 10 is selected for riveting, the support member 21 is rotated, and the position of the second elongated hole relative to the riveting nozzle 24 is adjusted so that at least one of the multiple through holes 11 corresponding to the projection area of ​​the support member 21 on the heating plate 10 matches the second elongated hole, and the fastener can pass through the second elongated hole and the through hole 11 in sequence to achieve positioning and matching between the second elongated hole and the through hole 11 of the heating plate 10, so that the center of the riveting nozzle 24 coincides with the point f on the heating plate 10. Among them, the extension direction of the second elongated hole at the sixth position f is different from the extension direction of the second elongated hole at the fifth position e or the fourth position d.

[0061] In this way, the support member 21 can rotate around the riveting nozzle 24, and the support member 21 is provided with a second long hole, which can be matched with one of the plurality of through holes 11, and then the distance between the fastener passing through the second long hole and the riveting nozzle 24 can be adjusted, so that the riveting position corresponding to any position in the heating plate 10 can be met, and the replacement of the heating plate 10 can be avoided, which helps to reduce the production cost. In addition, the operation is convenient and simple, which helps to reduce the complexity of the equipment.

[0062] According to some embodiments of the present invention, the riveting nozzle 24 has a connecting end 241 and a riveting end 242 that are arranged opposite to each other, and the connecting end 241 is detachably connected to the support member 21 to adjust the distance between the riveting end 242 and the support member 21 .

[0063] It should be noted that if Figure 1 or Figure 2 As shown, a riveting protrusion 31 is provided on a workpiece 30 to be riveted. The length of the riveting protrusion 31 has various sizes. Based on the different lengths of the riveting protrusion 31, the position of the riveting nozzle 24 in the Z direction needs to be adjusted. In this way, the riveting nozzle 24 can adapt to riveting protrusions 31 of different lengths.

[0064] Specifically, Figure 4 or Figure 5 As shown, the riveting tool 20 includes a riveting nozzle 24, a support member 21 and an adjusting nut 23. A connecting tube 212 is provided on the support member 21, and the adjusting nut 23 is connected to the connecting tube 212.
