Description

Technical Field

[0001] The utility model relates to the technical field of lithium batteries, in particular to a tab welding device. Background Art

[0002] Lithium metal batteries were first proposed and studied by Gilbert N. Lewis in 1912. In the 1970s, MS Whittingham proposed and began to study lithium-ion batteries. Due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements. Among power batteries, lithium batteries have many outstanding advantages over other batteries and are widely used. With the research on lithium batteries, people gradually understand the various characteristics of lithium batteries. Lithium batteries have the characteristics of high voltage, light weight, high energy density, etc., and can also be charged quickly. They have developed rapidly in modern society and have been applied in various fields of society.

[0003] Before the lithium battery test, the battery pole and the test pole ear need to be welded together by laser welding to achieve the purpose of testing. At present, the overall structure of the pole ear welding tool is relatively simple during use. During processing, it can only clamp batteries of a single specification. When the battery specifications are different, it cannot be positioned and processed, which causes a waste of resources and an increase in costs. Therefore, it needs to be improved.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in combination with the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0040] Embodiment 1:

[0041] like Figure 1-Figure 3As shown, the battery tab welding device includes a base 1, a guide rail 2, a telescopic mechanism 3, a slider 4, a clamping mechanism 5, and a receiving mechanism 6. The guide rail 2 is fixedly connected along the top surface of the base 1, the slider 4 is slidably connected to the guide rail 2, and the telescopic end of the telescopic mechanism 3 is connected to the slider 4 so that the slider 4 can move horizontally along the guide rail 2. The bottom of the clamping mechanism 5 is fixedly connected to the slider 4, and the clamping mechanism 5 is used to load the battery body 7. The clamping mechanism 5 can clamp the battery body 7 in the Y direction. The receiving mechanism 6 is connected to one end of the base 1 and can cooperate with the clamping mechanism 5 to clamp the battery body 7 in the X direction. The telescopic mechanism 3 and the receiving mechanism 6 are respectively located at the two ends of the guide rail 2.

[0042] Specifically, there are two guide rails 2, which are arranged in parallel. The guide rails 2 can be connected to the base 1 by bolts, and the base 1 is a long strip plate structure. The slider 4 and the guide rail 2 can be clamped with a convex or dovetail groove structure to improve the clamping and positioning stability during use.

[0043] The telescopic mechanism 3 is a cylinder, the fixed end of which is connected to the base 1 by bolts, welding, etc. and is located at one end of the guide rail 2. The telescopic end of the cylinder is connected to the slider 4, and the cylinder can provide power for the slider 4 to slide along the guide rail 2.

[0044] In this embodiment, the clamping mechanism 5 includes a square frame 51, an adjusting component 52, and a limiting component 53. The bottom of the square frame 51 is fixedly connected to the top of the slider 4, the adjusting component 52 is connected to the bottom of the square frame 51, and there are two limiting components 53. The two limiting components 53 are connected to the adjusting component 52 and can realize relative or opposite movement.

[0045] The top surface of the square frame 51 and the surface facing the receiving mechanism 6 are empty.

[0046] like Figure 2 As shown, the adjustment assembly 52 includes two chute 521, a screw rod 522, a knob 523, and a moving block 524. A partition plate is provided between the two chute 521. The chute 521 is provided on the bottom surface of the frame 51. The screw rod 522 passes through the two chute 521 and the partition plate. The two ends of the screw rod 522 can be rotatably connected to the wall of the frame 51. After one end of the screw rod 522 passes through the wall of the frame 51, a knob 523 is fixedly installed. The threads of the two sections of the screw rod located in the two chute 521 are rotated in opposite directions. The two sections of the screw rod 522 are connected to the moving block 524. The moving block 524 is limited in the chute 521 so that the moving block 524 can only move along the axial direction of the screw rod 522. The limiting method is that the length of the moving block 524 is slightly smaller than the width of the chute 521, so that the moving block 524 cannot be rotated by the screw rod 522 and can only move axially. The limiting assembly 53 is fixedly connected to the moving block 524 .

[0047] By turning the knob 523, the screw rod 522 is driven to rotate, and the screw rod 522 drives the two moving blocks 524 to slide against each other inside the slide groove 521, so that the distance between the two limit assemblies 53 can be adjusted, so as to facilitate adaptation to battery bodies 7 of different widths.

[0048] like Figure 4 As shown, in this embodiment, the limiting assembly 53 includes a limiting rail 531, a limiting bar 532, and a positioning bolt 533. The limiting rail 531 is fixedly connected to the top of the moving block 524, and the inner side of the limiting rail 531 is slidably connected to the limiting bar 532. The inner side of the limiting rail 531 is bent inward to form a notch, and the limiting bar 532 can slide along the length direction of the limiting rail 531. The outer right end of the limiting rail 531 is connected to the positioning bolt 533. After passing through the limiting rail 531, the positioning bolt 533 can abut on the limiting bar 532, and is used to tighten the limiting bar 532 through the positioning bolt 533 after the limiting bar 532 extends to a required length. In this embodiment, by setting a limiting track 531, during use, the screw rod 522 can be rotated to drive the relative movement of the moving block 524, and the limiting tracks 531 on both sides can move relative to each other to clamp and position the two sides of the battery body 7 in the Y direction. The limiting bar 532 can be adjusted to slide on the inner side of the limiting track 531, and then the limiting bar 532 can be extended to assist in limiting the batteries of different lengths or different numbers, thereby improving the positioning effect of the battery body 7.

[0049] like Figure 2 As shown, the receiving mechanism 6 of this embodiment includes a vertical plate 61, a collection frame 62, a slide plate 63, and a limit screw 64; the vertical plate 61 is fixedly installed on the top right end of the guide rail 2, the right side of the vertical plate 61 is connected to the collection frame 62, the collection frame 62 has a cavity, the internal cavity of the collection frame 62 is slidably connected with the slide plate 63, the left end of the slide plate 63 extends out after passing through the collection frame 62 and the vertical plate 61, the bottom left side of the collection frame 62 is connected to the limit screw 64, the top of the limit screw 64 passes through the collection frame 62, and the limit screw 64 can be locked after the slide plate 63 extends to the required length. By setting the receiving mechanism 6, during use of the device, the slide plate 63 in the collection frame 62 on the vertical plate 61 can be adjusted to slide, and then the vertical plate 61 can cooperate with the clamping mechanism 5 to clamp the battery body 7 in the Y direction. After the adjustment is completed, the slide plate 63 can be assisted in positioning by adjusting the rotation limit screw 64, thereby improving stability. The slide plate 63 is set to be adjustable in length, thereby facilitating the adjustment and positioning of battery bodies 7 of different lengths and different numbers, thereby improving the positioning flexibility and stability of the device. The bottom surface of the slide plate 63 is flush with the bottom surface of the frame 51, and together constitutes the bearing surface of the battery body 7.

[0050] During use of this embodiment, first adjust the slide plate 63 on the inner side of the collection frame 62 to slide to the left. At this time, the slide plate 63 slides to the left to adjust the receiving length of the top of the guide rail 2. Assuming that three battery bodies 7 with a width of A need to be clamped, the slide plate 63 needs to extend at least 2.6A (to ensure that the battery body 7 does not fall, and one or more battery bodies 7 can also be placed on the bottom surface of the frame 51). At this time, place the battery body 7 on the top of the slide plate 63, start the telescopic cylinder 3, and then push the slider 4 to slide on the inner side of the guide rail 2. At this time, the frame 51 can be driven to move to the right, and the frame 51 approaches the slide plate 63, forcing all the battery bodies 7 to move closer to the middle, and the battery bodies 7 are clamped and positioned. Then, the screw rod 522 is driven by adjusting the knob 523 to drive the moving block 524 to slide on the inner side of the guide rail 2, and then the moving block 524 drives the limit assembly 53 to move to limit the two sides of the battery body 7. At this time, the displacement of the limit assembly 53 can drive the limit assembly 53 to limit the battery body 7. At the same time, during use, the limit bar 532 on the inner side of the limit track 531 can be adjusted to slide. At this time, the limit assembly 53 can be assisted to extend, which is convenient for adjustment according to the number and length of the battery body 7, so that the device can position and weld the test pole ears 71 placed on battery bodies 7 of different lengths and numbers, effectively improving the practicality of the device.

[0051] Embodiment 2:

[0052] like Figure 4 As shown, in this embodiment, based on the first embodiment, the outer surface of the knob 523 is provided with anti-skid protrusions at equal intervals, so that it is not easy to slip when the knob 523 is turned.

[0053] This embodiment further adds a hand screw 525, which axially passes through the knob 523. After the knob 523 is screwed into place, the hand screw 525 can be twisted to press against the wall at the right end of the knob 523, so that the knob 523 is not easily reversed or moved. This improves the positioning stability of the device. The hand screw 525 is eccentric relative to the knob 523.

[0054] Embodiment three:

[0055] like Figure 4 As shown, on the basis of the above-mentioned embodiment 1 or embodiment 2, in this embodiment, a strip groove 534 is provided on the outer side of the limit strip 532, and the strip groove 534 is a rectangular notch, and anti-skid patterns 535 are provided at equal intervals in the strip groove 534, and the anti-skid patterns 535 can be vertical stripes. During use, the positioning bolt 533 can be inserted into the strip groove 534 by adjusting the twisting, and can be abutted between adjacent anti-skid patterns 535, thereby assisting in limiting the limit strip 532, thereby improving the stability of the device.

[0056] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that the technical solutions described in the aforementioned embodiments may still be modified, or some of the technical features may be replaced by equivalents.
