[0035] To make the objectives, technical solutions, and advantages of this application clearer, the embodiments of this application will be described in further detail below with reference to the accompanying drawings.

[0036] Figure 1 This is a schematic diagram of a welding equipment structure provided in an embodiment of this application. Please refer to it. Figure 1 One embodiment of this application provides a welding device 000, including: a base 010, a first carrier part 020, a second carrier part 030, and a welding component 040.

[0037] The first carrier part 020 is located on the base 010 and is slidably connected to the base 010.

[0038] The second carrier portion 030 is located on the side of the first carrier portion 020 away from the base 010 and is slidably connected to the first carrier portion 020. The side of the second carrier portion 030 away from the first carrier portion 020 is a bearing surface 031, which is used to support the part 100 to be welded.

[0039] The welding component 040 is connected to the base 010. The welding component 040 has a welding head 043, which is located on the side of the second carrier part 030 away from the first carrier part 020.

[0040] The first carrier portion 020 is slidable relative to the base 010 along a first direction, and the second carrier portion 030 is slidable relative to the first carrier portion 020 along a second direction. The first and second directions intersect, and both are parallel to the bearing surface 031.

[0041] In summary, since the first carrier portion can slide relative to the base along a first direction, and the second carrier portion can slide relative to the first carrier portion along a second direction, with the first and second directions intersecting and both parallel to the bearing surface supporting the part to be welded, when moving the part to be welded to align with the welding head, only the first and second carrier portions need to be moved, eliminating the need for manual movement of the part. This solves the safety hazard problem during welding. Furthermore, since the movement of both the first and second carrier portions is linear, it facilitates quick and accurate adjustment of the position of the part to be welded relative to the welding head, thus improving welding efficiency. It is understandable that when aligning the part to be welded 100 and the welding head 043, the positions of the first carrier part 020 and / or the second carrier part 030 can be adjusted according to the position of the part to be welded 100. That is, the position of the first carrier part 020 relative to the base 010 can be adjusted according to actual needs, while only the position of the second carrier part 030 relative to the first carrier part 020 can be adjusted, or the positions of the first carrier part 020 and the second carrier part 030 can be adjusted simultaneously to align the part to be welded 100 and the welding head 043, so that the welding head 043 can perform welding operations on the part to be welded 100.

[0042] Among them, the part to be welded 100 is the part that needs to be welded. For example, in the embodiment of this application, the part to be welded 100 is the data acquisition assembly (CCS) in the battery pack.

[0043] Figure 2 This is a schematic diagram of a CCS structure provided in an embodiment of this application. Please refer to [link / reference]. Figure 2 In one feasible embodiment, the CCS includes: an insulating protective plate 110, aluminum busbars 120, and conduits 130. The number of aluminum busbars 120 is at least one row, and each aluminum busbar 120 includes multiple aluminum sheets 121 arranged side-by-side. The number of conduits 130 corresponds one-to-one with the number of rows of aluminum busbars 120. Each conduit 130 includes: multiple pressure sampling wires 131, the ends of which extend from the conduit wall to facilitate subsequent welding with the corresponding aluminum sheets 121. The conduit 130 also includes: multiple temperature sampling wires 132, the ends of which also extend from the conduit wall. The end of the temperature sampling wire 132 located outside the conduit wall is connected to a temperature sensor 133. The temperature sensor 133 is connected to the corresponding aluminum sheet 121, for example, by temperature-sensitive adhesive.

[0044] The insulating plate 110 provides an installation surface for at least one row of aluminum bars 120, which facilitates the alignment and placement of multiple aluminum sheets 121 and multiple pressure lines 131 in the same aluminum bar 120. This frees up manpower, eliminates the need to press the pressure lines 131 with fingers, and effectively prevents finger injuries.

[0045] For example, the CCS includes: an insulating shield 110, two rows of aluminum bars 120 and two conduits 130, the arrangement direction of the two conduits 130 is parallel to the arrangement direction of the two rows of aluminum bars 120, and the two conduits 130 are located between the two rows of aluminum bars 120.

[0046] When welding the sampling lines 131 and corresponding aluminum sheets 121 on the CCS using the welding equipment 000 of this application, the CCS is fixed on the bearing surface 031 of the second carrier part 030. At this time, the arrangement direction of multiple aluminum sheets 121 in the same aluminum busbar 120 can be parallel to the second direction, and the arrangement direction of two rows of aluminum busbars 120 can be parallel to the first direction. In this way, when welding multiple aluminum sheets 121 in the CCS, by moving the first carrier part 020 to align the corresponding rows of aluminum busbars 120 and the welding head 043, it is only necessary to move the second carrier part 030 along the second direction to align the multiple aluminum sheets 121 in the same row with the welding head 043 respectively, so as to perform welding operations on the multiple aluminum sheets 121 and the corresponding sampling lines 131 in the same row of aluminum busbars 120 respectively.

[0047] When welding CCS using the welding equipment 000 of this application, the second carrier part 030, which moves along the second direction, can quickly perform welding operations on multiple aluminum sheets 121 and corresponding sampling lines 131 on the same row of aluminum bars 120 in the CCS. This improves welding efficiency and ensures the consistency of welding results, ensuring that multiple welding positions on the same aluminum bar 120 are aligned in a straight line. After welding one row of aluminum bars 120, the first carrier part 020 can be moved along the first direction to switch between different rows of aluminum bars 120 and the welding head 043 for alignment, facilitating welding of the next row of aluminum bars 120. This further improves the welding efficiency of CCS. Furthermore, during the welding process, there is no need for manual pressing of the sampling lines 131; only the corresponding first carrier part 020 and second carrier part 030 need to be moved, improving the safety of using the welding equipment 000.

[0048] Figure 3 This is a schematic diagram of another welding equipment structure provided in an embodiment of this application. Please refer to [link / reference]. Figure 3 In some feasible embodiments, the welding equipment 000 further includes a first guide structure 050. The first guide structure 050 is located between the first carrier portion 020 and the second carrier portion 030, and the second carrier portion 030 is used to slide relative to the first carrier portion 020 in a second direction via the first guide structure 050.

[0049] The first guide structure 050 can guide and limit the sliding of the second carrier part 030, ensuring the accuracy of the sliding direction of the second carrier part 030 relative to the first carrier part 020.

[0050] In one feasible implementation, the first guide structure 050 includes a slide rail 051 and a slider 052. The slide rail 051 is connected to either the first carrier portion 020 or the second carrier portion 030, and the slider 052 is connected to the other of the first carrier portion 020 and the second carrier portion 030. The slide rail 051 and the slider 052 are slidably connected.

[0051] Among them, the extension direction of slide rail 051 is parallel to the second direction.

[0052] For example, slide rail 051 is connected to first carrier part 020, and slider 052 is connected to second carrier part 030.

[0053] For example, in this embodiment of the application, the first direction may be perpendicular to the second direction to facilitate the movement of the welding equipment 000 carrying the part 100 to be welded. There may be two first guide structures 050, arranged along the first direction.

[0054] By using two first guide structures 050 arranged along the first direction, the smoothness of the sliding of the second carrier part 030 along the second direction and the accuracy of the direction can be ensured, thereby ensuring the precision of the welding position adjustment of the part to be welded 100.

[0055] In other feasible embodiments, the first guide structure 050 may further include: a slide groove and a slide bar, with a slide bar provided in either the first carrier portion 020 or the second carrier portion 030, and a slide groove provided in the other of the first carrier portion 020 and the second carrier portion 030. The slide groove and the slide bar cooperate with each other to guide and limit the movement of the second carrier portion 030.

[0056] This application does not impose any restrictions on the specific structural design of the first guide structure 050, as long as it can guide and limit the sliding of the second carrier part 030.

[0057] Figure 4 yes Figure 3 Please refer to the enlarged structural diagram at point A. Figure 4 In some feasible embodiments, the welding equipment 000 further includes a second guide structure 060. The first carrier portion 020 is connected to the base 010 via the second guide structure 060, and the first carrier portion 020 also slides relative to the base 010 in a first direction via the second guide structure 060.

[0058] The second guide structure 060 can guide and limit the sliding of the first carrier part 020, ensuring the accuracy of the sliding direction of the first carrier part 020 relative to the base 010.

[0059] Figure 5This is a schematic diagram of another welding equipment structure provided in the embodiments of this application. Please refer to [link / reference]. Figure 5 In one feasible implementation, the second guide structure 060 includes a guide member 061 and a guide groove 021. The guide groove 021 is located on the first carrier portion 020, and the extending direction of the guide groove 021 is parallel to the first direction. The guide member 061 is connected to the base 010, and at least a portion of the guide member 061 is located within the guide groove 021.

[0060] The guide member 061, which is at least partially located in the guide groove 021, together with the guide groove 021, can guide and limit the sliding of the first carrier part 020.

[0061] For example, at least two guide members 061 cooperate with the same guide groove 021, and the at least two guide members 061 are arranged in the first direction. In this way, the at least two guide members 061 located in the guide groove 021 can restrict the sliding direction of the first carrier part 020, ensuring that the first carrier part 020 can slide along the first direction, thereby ensuring the accuracy of the position adjustment of the part to be welded 100 carried on the second carrier part 030.

[0062] In one possible implementation, at least a portion of the guide member 061 passes through the guide groove 021 to be distributed between the first carrier portion 020 and the second carrier portion 030.

[0063] The welding equipment 000 also includes a locking member 070. The locking member 070 is used to connect with the portion of the guide member 061 that passes through the guide groove 021, to lock the first carrier portion 020 onto the base 010. To see more clearly... Figure 5 For the structure of the guide member 061 and the locking member 070, please refer to [link / reference]. Figure 6 , Figure 6 This is a schematic diagram of a guide and locking component structure provided in an embodiment of this application. For example, the locking component 070 is a nut, the guide component 061 is a column structure, and the guide component 061 has a stud section corresponding to the nut, so that the locking component 070 and the guide component 061 can be threadedly connected, thereby locking the first carrier part 020 onto the base 010.

[0064] The locking member 070 can accurately limit the position of the first carrier part 020 relative to the base 010 in the first direction, that is, limit the position of the second carrier part 030 and the part 100 to be welded thereon relative to the base 010 in the first direction. In this way, when the part 100 to be welded has multiple rows of welding positions, the position of the row of welding positions corresponding to the welding head 043 in the part 100 to be welded can be limited, so as to facilitate welding of multiple welding positions in that row.

[0065] Figure 7This is a schematic diagram of another welding equipment structure provided in the embodiments of this application. Please refer to [link / reference]. Figure 7 In some feasible embodiments, both the first carrier portion 020 and the second carrier portion 030 are plate-shaped structures.

[0066] The first carrier part 020 and the second carrier part 030 of the plate structure are simple in structure, easy to process, and can reduce the cost of welding equipment 000.

[0067] Figure 8 yes Figure 7 Please refer to the enlarged structural diagram at point B. Figure 8 In some feasible embodiments, the second carrier portion 030 has a positioning member 032 on the side opposite to the first carrier portion 020. The positioning member 032 is used to cooperate with the positioning hole on the part to be welded 100 to limit the part to be welded 100.

[0068] For example, the positioning element 032 is a positioning pin. The end of the positioning pin is pre-fixed to the side of the second carrier part 030 opposite to the first carrier part 020. When the part to be welded 100 is installed on the bearing surface 031, the part to be welded 100 can be limited and fixed by fitting the positioning hole on the part to be welded 100 onto the outside of the corresponding positioning element 032. After the welding operation of the part to be welded 100 is completed, the part to be welded 100 can be directly removed to proceed with the welding work of the next part to be welded 100.

[0069] By cooperating with the positioning hole in the positioning component 032 and the part to be welded 100, the part to be welded 100 can be quickly installed or removed on the bearing surface 031, which helps to improve the welding efficiency of multiple parts to be welded 100.

[0070] For example, there are four positioning members 032. Two positioning members 032 are respectively provided on both sides of the second carrier portion 030 along the second direction. The four positioning members 032 are used to securely fix the part to be welded 100 onto the bearing surface 031 of the second carrier portion 030.

[0071] Please see Figure 7 In some feasible embodiments, the welding equipment 000 further includes a lifting mechanism 080. One end of the lifting mechanism 080 is connected to the base 010, and the other end is connected to the welding component 040.

[0072] Among them, the lifting mechanism 080 is used to drive the welding component 040 to move upward in the third direction, which is perpendicular to the bearing surface 031.

[0073] When welding a row of welding positions in the part to be welded 100, the lifting mechanism 080 moves away from the second carrier part 030 to avoid the part to be welded 100. This allows the part to be welded 100 to be moved along the second direction by the second carrier part 030, so as to switch different welding positions and welding heads 043 for alignment.

[0074] Among them, welding head 043 is an ultrasonic welding head or a laser welding head.

[0075] For example, in this embodiment of the application, the welding head 043 is an ultrasonic welding head 043. See also... Figure 7 The welding equipment 000 also includes: an ultrasonic generator 041, a transducer 042, an amplitude transformer, and a welding head 043.

[0076] The ultrasonic generator 041, transducer 042, amplitude transformer and welding head 043 are arranged in sequence along the third direction. The ultrasonic generator 041 is located on the side away from the second carrier part 030, and the welding head 043 is located on the side close to the second carrier part 030.

[0077] One side of the ultrasonic generator 041 and the transducer 042 are connected, the other side of the transducer 042 is connected to one side of the amplitude transformer, the other side of the amplitude transformer is connected to one side of the welding head 043, and the other side of the welding head 043 is used to weld the part 100 to be welded.

[0078] The lifting mechanism 080 can be connected to the ultrasonic generator 041 at one end and the base 010 at the other end. The lifting mechanism 080 is, for example, a cylinder, to realize the lifting operation of the welding head 043.

[0079] Figure 9 This is an example diagram of a partial welding equipment structure provided in an embodiment of this application. Please refer to it. Figure 9 In one feasible implementation, the welding equipment 000 further includes a first displacement reference structure 090, which is used to assist the second carrier part 030 in sliding according to a preset distance.

[0080] Taking the part to be welded 100 as a CCS, including two rows of aluminum bars 120, each row of aluminum bars 120 having multiple aluminum sheets 121 as an example.

[0081] The preset distance can be the same as the distance between adjacent aluminum sheets 121.

[0082] In this way, when switching the aluminum sheet 121 corresponding to the welding head 043 in the same row, the aluminum sheet 121 corresponding to the welding head 043 can be quickly switched through the first displacement reference structure 090, thereby improving welding efficiency.

[0083] For example, the first displacement reference structure 090 includes a first scale 091 and a first positioning mark 092. The first scale 091 is distributed along a second direction, and the first scale 091 is set with corresponding graduations according to a preset distance. The first scale 091 is located on the edge of the first carrier portion 020 near the second carrier portion 030, and the first positioning mark 092 is located on the side of the second carrier portion 030 away from the first carrier portion 020 and near the edge of the first scale 091. Optionally, for example, the first positioning mark 092 is an arrow.

[0084] To facilitate alignment of the corresponding scale lines on the first positioning mark 092 and the first scale 091, the first carrier portion 020 and the second carrier portion 030 are staggered. For a clearer view of the distribution between the first carrier portion 020 and the second carrier portion 030, please refer to [link to relevant documentation]. Figure 10 , Figure 10 for Figure 9 A schematic diagram of the structure of a partial welding device from another perspective. Figure 10 In the middle, there is a staggered area with a distance of L between the left edges of the first carrier part 020 and the second carrier part 030. The first scale 091 is located on the first carrier part 020 within the staggered area so as to align the first positioning mark 092 and the first scale 091.

[0085] Please see Figure 10 The welding equipment 000 also includes a second displacement reference structure 0100, which is used to assist the first carrier part 020 in sliding according to a preset distance.

[0086] The second displacement reference structure 0100 includes a second scale 0101 and a second positioning mark 0102. The second scale 0101 is distributed along a first direction and can be located on the side wall of the base 010, while the second positioning mark 0102 can be located on the side wall of the first carrier part 020.

[0087] At this time, the preset distance can be set according to the spacing between adjacent rows of aluminum bars 120, so that the first carrier part 020 can be quickly moved by the second displacement reference structure 0100 to switch the aluminum bars 120 corresponding to the welding head 043.

[0088] In summary, since the first carrier portion can slide relative to the base along a first direction, and the second carrier portion can slide relative to the first carrier portion along a second direction, with the first and second directions intersecting and both parallel to the bearing surface supporting the part to be welded, when moving the part to be welded to align with the welding head, only the first and second carrier portions need to be moved, eliminating the need for manual movement of the part. This solves the safety hazard problem during welding. Furthermore, since the movement of both the first and second carrier portions is linear, it facilitates quick and accurate adjustment of the position of the part to be welded relative to the welding head, thus improving welding efficiency. It is understandable that when aligning the part to be welded 100 and the welding head 043, the positions of the first carrier part 020 and / or the second carrier part 030 can be adjusted according to the position of the part to be welded 100. That is, the position of the first carrier part 020 relative to the base 010 can be adjusted according to actual needs, while only the position of the second carrier part 030 relative to the first carrier part 020 can be adjusted, or the positions of the first carrier part 020 and the second carrier part 030 can be adjusted simultaneously to align the part to be welded 100 and the welding head 043, so that the welding head 043 can perform welding operations on the part to be welded 100.

[0089] In this application, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The term "multiple" refers to two or more unless otherwise expressly defined.

[0090] The above description is merely an optional embodiment of this application and is not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
