[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0029] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," "fixed," and "abutting" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0031] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0032] The following is based on the appendix Figure 1 To be continued Figure 2 This invention introduces the welding auxiliary device provided by this utility model.

[0033] like Figure 1 As shown, in this embodiment, the welding auxiliary device includes a battery positioning mechanism 1, a busbar fixing mechanism 2, and a mounting platform 3. The battery positioning mechanism 1 is used to fix the battery 100, and the busbar fixing mechanism 2 is used to fix the busbar 200. Both the battery positioning mechanism 1 and the busbar fixing mechanism 2 are connected to the mounting platform 3. By using the battery positioning mechanism 1 to fix the battery 100 and the busbar fixing mechanism 2 to fix the busbar 200, the battery 100 and the busbar 200 can be brought into contact and kept relatively fixed during welding, thus facilitating the welding process and effectively ensuring welding quality.

[0034] Specifically, refer to Figure 1As shown, the busbar fixing mechanism 2 includes a first base 21, which is connected to the mounting platform 3 and is fixedly arranged relative to the battery positioning mechanism 1 along a preset first direction (as shown by the X-axis in the figure) and a preset second direction (as shown by the Y-axis in the figure). Optionally, in this embodiment, the mounting platform 3 is arranged parallel to the horizontal plane, and the preset first direction and the preset second direction are two mutually perpendicular directions in the horizontal plane.

[0035] Continue to refer to Figure 1 As shown, the busbar fixing mechanism 2 also includes a second sliding connector 24, a first connecting arm 25, a first sliding connector 27, a second connecting arm 26, a rotating connector 28, and a fixing assembly 29. The fixing assembly 29 is used to fix the busbar 200, securing it to the pole post 101 during welding for easier welding. Furthermore, the fixing assembly 29 is rotatably connected to the second connecting arm 26 via the rotating connector 28. The second connecting arm 26 is slidably connected to the first connecting arm 25 via the first sliding connector 27, and the first connecting arm 25 is slidably connected to the first base 21 via the second sliding connector 24. This allows the fixing assembly 29 to be movably positioned relative to the first base 21, enabling it to change position and angle relative to the first base 21.

[0036] When welding the busbar 200 to batteries 100 of different sizes or with different terminal post 101 positions, the busbar 200 to be welded can be accurately moved to the terminal post 101 by adjusting the position between the fixing component 29 and the battery positioning mechanism 1. This allows the busbar 200 and the terminal post 101 to abut against each other along a preset third direction (as shown by the Z-axis in the figure), facilitating the welding process. When it is necessary to weld the busbar 200 and the terminal post 101 at different preset angles, the fixing component 29 can be rotated relative to the second connecting arm 26 to change the setting angle of the busbar 200, thereby ensuring that the included angle between the busbar 200 and the terminal post 101 meets the corresponding preset angle. Specifically, this preset third direction is perpendicular to the aforementioned preset first direction and preset second direction; that is, in this embodiment, the preset third direction is the vertical direction.

[0037] This welding auxiliary device allows for the separate fixing of the busbar 200 and the battery 100, eliminating the need for constant control of the busbar 200 during welding. This simplifies the welding process, improves efficiency, and prevents positional deviations caused by manual fixing of the busbar 200, thus ensuring welding quality. Furthermore, the device can adjust the distance between the fixing component 29 and the battery positioning mechanism 1, allowing the busbar 200 to be welded to the terminal post 101 at a preset angle. This adaptable device is suitable for batteries 100 of different sizes and different busbar 200 angles, meeting various electrical connection and welding requirements.

[0038] Specifically, in this embodiment, the end of the fixing component 29 away from the second connecting arm 26 is used to fix the busbar 200, and the end of the fixing component 29 close to the second connecting arm 26 is rotatably connected to the second connecting arm 26 via the rotating connector 28. By rotating the fixing component 29 around the rotating connector 28, the operator can change the relative angle between the busbar 200 and the terminal 101, thereby welding the busbar 200 and the terminal 101 at a preset angle.

[0039] For example, in this embodiment, the rotating connector 28 includes a rotating shaft mounted on the end of the second connecting arm 26 away from the first connecting arm 25. The fixing component 29 is connected to the rotating shaft to rotatably connect the fixing component 29 and the second connecting arm 26. The axial direction of the rotating shaft is parallel to a preset third direction, so that when the fixing component 29 is rotated, the relative angle between the busbar 200 and the pole post 101 about the preset third direction can change until the preset angle is reached.

[0040] It should be noted that in this embodiment, the preset angle can be a relative angle about a preset third direction, thus applicable to the common case where the top surface of the pole post 101 is horizontal. In other embodiments, by setting the axis of the rotating shaft parallel to a preset first direction or parallel to a preset second direction, the preset angle can also be a relative angle about the preset first or preset second direction, applicable to the inclined welding surface of the irregular pole post 101. Alternatively, in some other embodiments, by setting a more complex rotating connector 28, such as a rotating connector 28 with multiple rotating shafts connected in sequence, the relative angle between the busbar 200 and the pole post 101 can be adjusted simultaneously about the preset first direction, the preset second direction, and the preset third direction. Therefore, the preset angle is not specifically limited in this utility model, as long as it meets the welding requirements of the pole post 101 and the busbar 200.

[0041] More specifically, the fixing assembly 29 includes a lower clamping member 292 and an upper clamping member 291. The lower clamping member 292 is rotatably connected via a rotating connector 28 and a second connecting arm 26. The upper clamping member 291 is detachably connected to the lower clamping member 292, and the busbar 200 can be placed between the lower clamping member 292 and the upper clamping member 291, thereby being clamped and fixed by the lower clamping member 292 and the upper clamping member 291. Optionally, refer to Figure 1 As shown, both the upper clamping member 291 and the lower clamping member 292 are U-shaped to avoid obstructing the central welding area of ​​the busbar 200, thus improving welding efficiency. Of course, in some embodiments, the upper clamping member 291 can also be L-shaped, straight, or other shapes, as long as it works in conjunction with the lower clamping member 292 to fix the busbar 200, it falls within the scope of protection of this utility model.

[0042] Continue to refer to Figure 1 As shown, in this embodiment, both the first connecting arm 25 and the second connecting arm 26 have a first connecting groove 251. The first sliding connector 27 is disposed through the first connecting groove 251, thereby slidably connecting the first connecting arm 25 and the second connecting arm 26, so that the second connecting arm 26 moves relative to the first connecting arm 25 in a direction close to the battery positioning mechanism, thereby changing the distance between the busbar 200 and the terminal post 101 along a preset first direction.

[0043] Optionally, the first sliding connector 27 includes a bolt and a nut. The bolt passes through two first connecting slots 251 and connects with the nut, thereby connecting the first connecting arm 25 and the second connecting arm 26. When it is necessary to adjust the relative position between the first connecting arm 25 and the second connecting arm 26, by unscrewing the nut, the distance between the bolt and the nut is made greater than the sum of the thicknesses of the first connecting arm 25 and the second connecting arm 26. This allows the first connecting arm 25 and the second connecting arm 26 to slide relative to each other under manual adjustment, thereby adjusting the position of the second connecting arm 26. After the position is adjusted, by screwing in the nut, the nut and the bolt clamp and fix the first connecting arm 25 and the second connecting arm 26, ensuring that the first connecting arm 25 and the second connecting arm 26 maintain the adjusted relative positional relationship, thus ensuring the fixation of the busbar 200 during welding.

[0044] It should be noted that in some embodiments, the first connecting groove 251 may be provided only in one of the first connecting arm 25 and the second connecting arm 26, and a connector through hole may be provided in the other of the first connecting arm 25 and the second connecting arm 26. The first sliding connector 27 passes through the first connecting groove 251 and the connector through hole, which can also achieve the sliding connection between the first connecting arm 25 and the second connecting arm 26.

[0045] Meanwhile, the number of bolts passing through the first connecting groove 251 is not specifically limited in this utility model. For example, when only one bolt passes through the first connecting groove 251, the first connecting arm 25 and the second connecting arm 26 can adjust their relative positions and also adjust their relative angles around the bolt's axis. Optionally, in some embodiments, when the bolt's axis is parallel to a preset second direction, the relative angle between the first connecting arm 25 and the second connecting arm 26 around the preset second direction can be changed, thereby adjusting the distance between the fixing component 29 and the battery positioning mechanism 1 along a preset third direction, thus making the welding auxiliary device applicable to batteries 100 with poles 101 of different heights. Of course, in some embodiments, the axis of the aforementioned rotating shaft can also be set parallel to the preset second direction, thereby ensuring that the busbar 200 can be parallel to the top surface of the pole 101 by rotating the fixing component 29 around the preset second direction, reducing welding difficulty and ensuring welding quality.

[0046] Of course, in some embodiments, two or more bolts may be inserted into the first connecting groove 251, so that the first connecting arm 25 and the second connecting arm 26 can be connected more stably, which is also within the scope of protection of this utility model.

[0047] Continue to refer to Figure 1 As shown, in this embodiment, the adjusting member 23 has a second connecting groove 231, and a second sliding connector 24 is disposed through the second connecting groove 231. The end of the first connecting arm 25 away from the second connecting arm 26 is connected to the second sliding connector 24, thereby connecting the first connecting arm 25 and the adjusting member 23 via the second sliding connector 24. Furthermore, the second sliding connector 24 can slide along the second connecting groove 231, thereby moving the first connecting arm 25, the first sliding connector 27, the second connecting arm 26, the rotating connector 28, the fixing assembly 29, and the busbar 200 along the second connecting groove 231, so that the position of the busbar 200 matches the terminal post 101 of the battery 100. In this embodiment, the second connecting groove 231 is disposed along a preset second direction, so that by moving the second sliding connector 24 along the second connecting groove 231, the position of the busbar 200 can be changed along the preset second direction. In some other embodiments, the second connecting groove 231 may also be set along a preset first direction or other directions. As long as the position of the busbar 200 can be adjusted to meet the welding requirements, it falls within the scope of protection of this utility model.

[0048] Preferably, in this embodiment, the first base 21 is provided with a slide rail 22, which extends along a preset first direction. The adjusting member 23 is slidably connected to the first base 21 via the slide rail 22, so that the first connecting arm 25 can move relative to the first base 21 in a direction close to the battery positioning mechanism. In this way, in conjunction with the second connecting groove 231 provided along a preset second direction, the position adjustment of the busbar 200 along the preset first direction and the preset second direction can be achieved without adjusting the first connecting arm 25 and the second connecting arm 26.

[0049] For example, during welding, once the relative positions and angles between the fixing component 29, the second connecting arm 26, the first connecting arm 25, and the adjusting component 23 are all set in place, the battery 100 can be easily removed and placed into the battery positioning mechanism 1 by moving the adjusting component 23 along a preset first direction away from the battery 100. Simultaneously, the fixing component 29 can be easily moved along the preset first direction and approach the terminal post 101, thereby allowing the busbar 200 to abut against the terminal post 101, facilitating the welding process. Optionally, the adjusting component 23 is also provided with a handle 232, allowing the operator to easily adjust the position of the adjusting component 23 by gripping the handle 232.

[0050] Preferably, in this embodiment, the adjusting member 23 is slidably connected to two second sliding connectors 24. Each second sliding connector 24 is sequentially connected to a first connecting arm 25, a first sliding connector 27, a second connecting arm 26, a rotating connector 28, and a fixing component 29. The aforementioned second connecting groove 231 extends along a preset second direction, allowing the two second sliding connectors 24 to approach each other to reduce the distance between the two first connecting arms 25, and allowing the two second sliding connectors 24 to move away from each other to increase the distance between the two first connecting arms 25.

[0051] Reference Figure 1 As shown, the top of the battery 100 is provided with two terminals 101, and two fixing components 29 can respectively fix one busbar 200, thereby achieving simultaneous contact and welding of the two terminals 101 and the two busbars 200. When the distance between the two terminals 101 on the battery 100 is large, the two first connecting arms 25 can be moved away from each other by moving the two second sliding connectors 24 away from each other, thereby increasing the distance between the two fixing components 29, so that the distance between the two busbars 200 corresponds to the larger distance between the two terminals 101. When the distance between the two terminals 101 on the battery 100 is small, the two first connecting arms 25 can be moved towards each other by bringing the two second sliding connectors 24 closer together, thereby decreasing the distance between the two fixing components 29, so that the distance between the two busbars 200 corresponds to the smaller distance between the two terminals 101.

[0052] Optionally, in this embodiment, the second sliding connector 24 also includes a bolt and a nut. The first connecting arm 25 is provided with a mounting hole. The bolt passes through the second connecting groove 231 and the mounting hole and is connected to the nut. It can cooperate with the nut to clamp and fix the first connecting arm 25 and the adjusting member 23, thereby ensuring stability during welding. When it is necessary to adjust the position of the second sliding connector 24, by unscrewing the nut, the abutment pressure and friction between the first connecting arm 25 and the adjusting member 23 can be eliminated, thereby facilitating the movement of the first connecting arm 25 and the second sliding connector 24 to achieve position adjustment.

[0053] like Figure 1 , 2 As shown, in this embodiment, the battery positioning mechanism 1 includes a first limiting member 11, a second limiting member 12, and a third limiting member 13. The first limiting member 11 and the second limiting member 12 are movably disposed relative to each other along a preset second direction, allowing them to approach each other to clamp and fix the battery 100, and to move away from each other to release the battery 100. Along a preset first direction, the third limiting member 13 is disposed on the side of the first limiting member 11 and the second limiting member 12 away from the fixing component 29. A battery clamping space is defined between the first limiting member 11, the second limiting member 12, and the third limiting member 13, which can fix and limit the battery 100, thereby providing conditions for the implementation of the welding process. Optionally, the mounting platform 3 is also provided with a guide rail (not shown in the figure), which extends along a preset second direction. The first limiting member 11 and the second limiting member 12 are slidably mounted on the guide rail so that the first limiting member 11 and the second limiting member 12 can move towards each other and move away from each other, thereby realizing the clamping and release of the battery 100.

[0054] Reference Figure 2 As shown, the battery positioning mechanism 1 includes at least one replaceable pad 14. Along a preset third direction, the replaceable pad 14 can be disposed between the battery 100 and the mounting platform 3, and abuts against the side of the battery 100 away from the fixing component 29, thereby changing the distance between the fixing component 29 and the battery 100 along the preset third direction. For example, when the height of the battery 100 is small, by providing a thicker replaceable pad 14, the terminal 101 and the busbar 200 can abut against each other along the preset third direction. When the height of the battery 100 is large, by providing a thinner replaceable pad 14 or not providing a replaceable pad 14, the distance between the terminal 101 and the mounting platform 3 can be changed individually, ensuring that the terminal 101 and the busbar 200 abut against each other along the preset third direction for batteries 100 with different heights.

[0055] Optionally, in some embodiments, an elastic element, such as a spring or sheet, is connected to the side of the battery 100 away from the fixing component 29. During the welding process, the elastic element is in a deformed state and can apply a spring force to the battery 100 toward the busbar 200, thereby ensuring that the terminal post 101 and the busbar 200 abut against each other along a predetermined third direction. Specifically, when a spring is selected as the elastic element, multiple springs are arranged in an array between the first limiting member 11, the second limiting member 12, and the third limiting member 13, thereby applying a uniform and balanced spring force to the battery 100. When a sheet is selected as the elastic element, a wavy sheet can be used to achieve a similar effect and is also within the scope of protection of this utility model.

[0056] When using the aforementioned welding auxiliary device, for example, if it is necessary to match the positions of the busbar 200 and the terminal 101 along a preset first direction, the relative position between the first connecting arm 25 and the second connecting arm 26 can be changed by the first sliding connector 27, so that the second connecting arm 26 moves in a direction closer to or further away from the battery 100. If it is necessary to match the positions of the busbar 200 and the terminal 101 along a preset second direction, the relative position between the first connecting arm 25 and the adjusting member 23 can be changed by the second sliding connector 24, so that the first connecting arm 25 moves along the preset second direction. If it is necessary to match the positions of the busbar 200 and the terminal 101 along a preset third direction, the distance between the terminal 101 and the mounting platform 3 can be changed by setting replaceable shims 14 of different thicknesses. If it is necessary to change the relative angle between the busbar 200 and the terminal 101, the fixing component 29 can be rotated around the rotating connector 28 until the relative angle between the busbar 200 and the terminal 101 is a preset angle. After the aforementioned positional adjustments along the preset first, second, and third directions are completed, and the relative angle between the busbar 200 and the terminal post 101 is adjusted, the adjusting member 23 can be moved along the preset first direction by the handle 232, so that the busbar 200 approaches the battery positioning mechanism until it abuts against the terminal post 101, thereby achieving welding. Furthermore, by moving the adjusting member 23 away from the battery positioning mechanism, the busbar 200 can be moved away from the battery positioning mechanism to avoid interference or collision between the battery 100 and the busbar 200 and other structures during the removal and placement of the battery.

Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model.
