[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model.
[0025] Example:
[0026] like Figures 1 to 7As shown, this utility model provides a battery tab spot welding and fixing fixture for battery manufacturing, including a base plate 11. The base plate 11 provides basic support for the entire fixture and supports other components. The base plate 11 has a fixing assembly and a battery cell body 13. The fixing assembly includes multiple sets of fixing plates 12, which are slidably disposed on the base plate 11. The battery cell body 13 is fixedly connected to the base plate 11 through the multiple sets of fixing plates 12. The multiple sets of fixing plates 12 allow for position adjustment according to the size of the battery cell body 13, thereby fixing the battery cell body 13. The base plate 11 also has a welding seat 14 and a tab 15. The welding seat 14 has an adjustment assembly and two sets of limiting angles 18. The welding seat 14 provides a placement platform for the tab 15 and integrates the adjustment assembly and limiting angles 18 to achieve positioning and adjustment of the tab 15. The two sets of limiting angles 18 are slidably connected to the welding seat 14, allowing for adjustment according to the size and position of the tab 15. The adjustment assembly includes a telescopic component located below the welding base 14. This component allows for height adjustment of the welding base 14 to accommodate different welding requirements. The electrode tab 15 is located on the welding base 14, and its support structure ensures it has a designated position during welding. A mounting assembly is located at the bottom of the base plate 11. This assembly allows the fixture to be mounted on the worktable, preventing movement during spot welding.
[0027] like Figure 2 , 5 As shown, the fixing assembly also includes a spring plate 16, which is mounted on two of the fixing plates 12. The spring plate 16 secures the battery cell body 13. Multiple sets of sliding grooves 17 are formed on the base plate 11. One end of each fixing plate 12 passes through a sliding groove 17 and is fixedly connected to the base plate 11 by a first nut. The multiple sliding grooves 17 and the first nut allow the fixing plates 12 to slide on the sliding grooves 17 and be fixed in the desired position by the first nut, thus achieving the fixing of battery cell bodies 13 of different sizes.
[0028] like Figure 2 , 4 As shown, the welding base 14 is equipped with a slide rail 23, and a bidirectional lead screw 24 is installed inside the slide rail 23. Two sets of limiting angles 18 are located inside the slide rail 23 and are sleeved on the bidirectional lead screw 24. Through the arrangement of the slide rail 23 and the bidirectional lead screw 24, the two sets of limiting angles 18 can move in relative or opposite directions along the slide rail 23, adjusting the distance between the limiting angles 18 to accommodate pole lugs 15 of different widths. One end of the bidirectional lead screw 24 is equipped with an adjusting rod 25. The adjusting rod 25 allows the operator to easily rotate the bidirectional lead screw 24 to adjust the position of the limiting angles 18.
[0029] like Figure 2 ,3 As shown, the telescopic component includes an inner cylinder 19 and an outer cylinder 21. A fixing seat 22 is provided below the welding base 14. The fixing seat 22 provides fixed support for the outer cylinder 21, ensuring the stability of the telescopic component structure. One end of the outer cylinder 21 is fixed to the fixing seat 22, and the other end of the outer cylinder 21 passes through one set of sliding grooves 17 and is fixedly connected to the base plate 11 by a second nut. Through the outer cylinder 21, sliding grooves 17, and the second nut, the telescopic component can be connected to the base plate 11, and the outer cylinder 21 can be adjusted to a certain position within the sliding grooves 17 to meet different installation and adjustment requirements. One end of the inner cylinder 19 is connected to the welding base 14, and the other end passes through the outer cylinder 21. Through the sleeve connection between the inner cylinder 19 and the outer cylinder 21, the telescopic function of the telescopic component can be realized, thereby adjusting the height of the welding base 14.
[0030] like Figure 2 , 7 As shown, the adjustment assembly includes four sets of guide rods 26, one end of each guide rod 26 being fixed to the welding seat 14. The four sets of guide rods 26 provide guidance for the vertical movement of the welding seat 14. Two sets of guide grooves 27 are provided on the base plate 11, and the other end of each guide rod 26 extends through the fixing seat 22 into the guide groove 27. The guide grooves 27, in conjunction with the guide rods 26, further limit the movement trajectory of the welding seat 14, enhancing the stability and reliability of the adjustment assembly.
[0031] Each of the multiple sets of slides 17 has a scale line 28 on one side, and each of the multiple sets of fixing plates 12 and fixing seats 22 has an indicator needle 29. The scale line 28 and indicator needle 29 allow the operator to intuitively understand the positional changes of the fixing plate 12 and fixing seat 22.
[0032] like Figure 2 , 6 As shown, the mounting assembly includes a clamping plate 31. An adjustment groove 32 is provided on the base plate 11. One end of the clamping plate 31 is located within the adjustment groove 32. The clamping plate 31 and the adjustment groove 32 allow for position adjustment within the adjustment groove 32 to accommodate worktables of different thicknesses. A lead screw 33 is provided within the adjustment groove 32, and the clamping plate 31 is sleeved on the lead screw 33. One end of the lead screw 33 has an adjustment knob 34. By rotating the adjustment knob 34, the lead screw 33 can be rotated, thereby controlling the position of the clamping plate 31 within the adjustment groove 32 and achieving clamping between the fixture and the worktable.
[0033] The specific usage and function of this embodiment are as follows:
[0034] When using this battery manufacturing battery tab spot welding fixture, the base plate 11 is first placed on the worktable, which serves as the basic support to bear all the components of the fixture. Next, the battery cell body 13 is placed on the base plate 11. According to the size of the battery cell, multiple sets of fixing plates 12 are slid along the slide groove 17 of the base plate 11. There are three sets of fixing plates 12. After the spring plates 16 on two sets of fixing plates 12 contact the battery cell body 13, the remaining fixing plate 12 is located at the bottom of the battery cell body 13. The first nut is tightened to fix it. The fixing plates 12 and the spring plates 16 cooperate to adapt to the size of the battery cell, and can stably fix it without damaging the battery cell. Next, the electrode tab 15 is placed on the welding seat 14, and the adjusting rod 25 at one end of the bidirectional lead screw 24 is rotated to move the two sets of limiting angles 18 on the bidirectional lead screw 24 along the slide rail 23 to adjust to the appropriate position to limit the electrode tab 15. The welding seat 14 provides a placement platform, and the slide rail 23, bidirectional lead screw 24 and adjusting rod 25 cooperate to adjust the limiting angles 18 to accommodate the electrode tab 15. If the height of the welding seat 14 needs to be adjusted, the inner cylinder 19 will extend and retract within the outer cylinder 21. One end of the outer cylinder 21 is supported by the fixed seat 22, and the other end passes through the slide groove 17 and is connected to the substrate 11 through the second nut. The nut can be loosened as needed to adjust the position and then fixed again, so that the height of the welding seat 14 can adapt to different spot welding processes. At the same time, one end of the guide rod 26 is fixed to the welding seat 14, and the other end passes through the fixed seat 22 and extends into the guide groove 27 of the substrate 11. It plays a guiding role when the welding seat 14 is raised and lowered to ensure its stability and prevent deviation. When adjusting the fixed plate 12 and related operations with the fixed base 22, the operator controls the adjustment amount by observing the scale line 28 on one side of the slide groove 17 and the indicator needle 29 on the fixed plate 12 and the fixed base 22. Finally, using the mounting component fixing fixture, one end of the clamping plate 31 is placed in the adjustment groove 32, and the adjustment knob 34 is rotated to drive the lead screw 33, so that the clamping plate 31 moves in the adjustment groove 32 to abut against the worktable, thereby fixing the fixture, preventing movement during spot welding, ensuring the quality of spot welding, and the adjustment groove 32 can also adapt the clamping plate 31 to worktables of different thicknesses.
[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It is obvious to those skilled in the art that this utility model is not limited to the details of the above exemplary embodiments.
