Abstract
Description
Technical Field
[0001] This utility model relates to a positioning device, specifically a positioning device for welding lithium battery terminals. Background Technology
[0002] During lithium battery manufacturing, adapter plates need to be welded to the lithium battery terminals. Before welding, a positioning device is required to hold both together to facilitate welding. Current welding equipment typically fixes the adapter plates and terminals by clamping or pressing. Once fixed, they cannot be adjusted. Furthermore, some adapter plates have irregular shapes. If the terminals directly contact the adapter plates, the contact will not be complete, resulting in an incomplete weld. This makes welding adapter plates with unusual shapes particularly inconvenient. Utility Model Content
[0003] The purpose of this utility model is to provide a positioning device for welding lithium battery terminals. By setting an adjustment component on the limiting ring, its angle can be finely adjusted according to actual needs. Adapters of different shapes can make close contact with the terminals, resulting in better subsequent welding effects.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a positioning device for welding lithium battery terminals, comprising a first positioning mechanism and a second positioning mechanism disposed on the first positioning mechanism.

[0008] Preferably, a gasket is fixedly bonded to one end of each of the two positioning seats facing each other; the gasket can be made of rubber or silicone and is used to buffer the adapter piece, so that the two positioning seats limit the adapter piece.
[0009] Preferably, a rotary knob is fixedly connected to the inner support shaft, and multiple toothed grooves are provided on the circumference of the rotary knob.
[0010] Preferably, a support is fixed to one end of the support arm near the limiting ring, and a fixing seat is fixed to the support.
[0011] Preferably, an elastic lever is provided at the end of the fixed seat away from the support; the elastic lever engages with the tooth groove, and the fixed seat is elastically designed on the support, so that the fixed seat can elastically deform within a certain range.

[0024] Please see Figure 1One embodiment of this utility model is a positioning device for welding lithium battery terminals, comprising a first positioning mechanism 1 and a second positioning mechanism 2 disposed on the first positioning mechanism 1.
[0025] Please see Figure 2 The first positioning mechanism 1 includes a welding table 11, and a material groove 12 and a lower extension groove 13 located below the material groove 12 are provided on the upper end surface of the welding table 11.
[0026] Please see Figure 3 Both sides of the lower extension groove 13 extend into the welding table 11. Bottom grooves 14 are provided on both sides of the lower end face of the welding table 11. Two servo motors 15 are mounted on the welding table 11, each fixed within a bottom groove 14, and both servo motors 15 are horizontal. Screws 16 are fixedly connected to the output ends of the servo motors 15. Two screws 16 are provided, and both screws 16 are rotatably connected to the welding table 11, allowing both screws 16 to operate stably. Threads are installed on the screws 16. The slider 17 fits against the inner wall of the lower extension groove 13, so that the screw 16 can drive the slider 17 to move along the inner wall of the lower extension groove 13 when it is running. A positioning seat 18 is fixedly connected to the end of the slider 17 away from the screw 16. There are two positioning seats 18, and both positioning seats 18 are U-shaped. A gasket 19 is fixedly glued to the opposite end of the two positioning seats 18. The gasket 19 can be made of rubber or silicone and is used to buffer the adapter piece, so that the two positioning seats 18 limit the adapter piece.
[0027] Please see Figure 4 The second positioning mechanism 2 includes a support arm 21 and a limiting ring 25 disposed on the support arm 21. A U-shaped storage seat 22 is disposed between the support arm 21 and the limiting ring 25. An inner support shaft 23 is rotatably connected inside the storage seat 22. A connecting block 24 is fixed on the inner support shaft 23. The limiting ring 25 is fixedly connected to the end of the connecting block 24 away from the inner support shaft 23. A rotary knob 26 is fixedly connected to the inner support shaft 23. A support 27 is fixed on the end face of the support arm 21 near the limiting ring 25.
[0028] Please see Figure 5 Multiple toothed grooves 261 are provided on the circumference of the rotary knob 26. A fixed seat 28 is fixed on the support 27. An elastic paddle 281 is provided at the end of the fixed seat 28 away from the support 27. The elastic paddle 281 is engaged with the toothed grooves 261. The fixed seat 28 is elastically designed on the support 27, so that the fixed seat 28 can be elastically deformed within a certain range. The fixed seat 28 can be made of plastic or metal, so that the elastic paddle 281 can be engaged in or disengaged from a designated toothed groove 261, thereby allowing the rotary knob 26 to rotate.
[0029] Please refer to the following: Figures 1 to 5 In this invention, the adapter piece is placed in the lower extension groove 13, driving two servo motors 15 to rotate two screws 16, causing two sliders 17 to move closer together, ultimately bringing two positioning seats 18 close to the adapter piece. Finally, the two gaskets 19 contact the adapter piece, thus limiting the adapter piece with the positioning seats 18. Then, the worker inserts the lithium battery terminal from top to bottom through the limiting ring 25, ensuring the bottom of the terminal contacts the area to be welded on the adapter piece. Welding can then be performed using welding equipment (the limiting ring 25 does not contact the terminal piece; it only provides a general limiting effect). If the contact position between the adapter piece and the terminal piece is not horizontal (this... In this state (the adapter cannot fully contact the pole), you can hold the limiting ring 25 and make it rotate within a certain angle with the inner support shaft 23. During the rotation of the inner support shaft 23, the rotating knob 26 will rotate, so that the elastic lever 281 will gradually pass over one or more toothed grooves 261 on the rotating knob 26. Finally, the elastic lever 281 will still be engaged in a toothed groove 261. This can ensure that the rotating knob 26 will not arbitrarily drive the inner support shaft 23, the connecting block 24 and the limiting ring 25 to rotate, and can also make fine adjustments to the angle of the limiting ring 25 and the pole inserted in it, which can meet the welding requirements of various complex-shaped adapters and poles.
[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
