The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present invention, and should not be construed as limiting the present invention.

[0026] The lithium battery assembly workbench according to an embodiment of the present invention will be described below with reference to the accompanying drawings.

[0027] like Figure 1 and Figure 2 As shown, the lithium battery assembly workbench of the embodiment of the present invention may include a workbench 100 , a bracket 200 , a driving cylinder 300 , a spot welder 400 , a rotating table 500 and a positioning device 600 .

[0028] Among them, the bracket 200 is mounted on the workbench 100, the driving cylinder 300 and the spot welder 400 are respectively arranged on the bracket 200, the telescopic end of the driving cylinder 300 extends vertically downward, and the working end of the spot welder 400 is arranged on the telescopic end of the driving cylinder 300.

[0029] The rotating table 500 is rotatably disposed on the working table 100 .

[0030] As a possible scenario, a groove is provided on the workbench 100 , and the rotating platform 500 can be rotatably disposed in the groove, and the top of the rotating platform 500 is slightly higher than the table surface of the workbench 100 .

[0031] The two positioning ends of the positioning device 600 are movably arranged on both sides of the workbench 100 to position the lithium battery 700 on the rotating table 500. Figure 3 As shown, the positioning device 600 includes a bidirectional screw 610 , a screw slider 620 , a limiting structure 630 and a drive motor 640 .

[0032] Among them, the bidirectional screw 610 is arranged at the bottom of the workbench 100, and the two screw sliders 620 are respectively arranged at the two ends of the bidirectional screw 610. Slide grooves 101 are respectively opened on both sides of the workbench 100. The two limiting structures 630 are respectively connected to the corresponding screw sliders 620, and extend through the slide grooves 101 to the workbench 100. The output end of the drive motor 640 is connected to the bidirectional screw 610.

[0033] It should be noted that a fixing frame 601 is provided at the bottom of the workbench 100 , a bidirectional lead screw 610 is rotatably provided on the fixing frame 601 , and a driving motor 640 is provided outside the fixing frame 601 and connected to the bidirectional lead screw 610 .

[0034] To clearly illustrate the above embodiment, in one embodiment of the present invention, Figure 4 As shown, the limiting structure 630 includes a sliding plate 631 , an extension rod 632 , a longitudinal plate 633 , a transverse plate 634 and a limiting plate 635 .

[0035] Among them, the sliding plate 631 is connected to the screw slider 620, and vertically extends upward through the slide groove 101, the extension rod 632 is set on the extended end of the sliding plate 631, the longitudinal plate 633 is fixed on the extension rod 632, and the transverse plate 634 can be rotatably set on the longitudinal plate 633 and limited by the limiting plate 635. Among them, the longitudinal plate 633 and the transverse plate 634 in the two limiting structures 630 jointly limit the lithium battery 700.

[0036] As a possible scenario, Figure 5As shown, a first magnetic block 6341 is embedded in the transverse plate 634, and a second magnetic block 6351 is embedded in the limiting plate 635. When the transverse plate 634 is limited by the limiting plate 635, the first magnetic block 6341 and the second magnetic block 6351 are magnetically connected.

[0037] It should be noted that when positioning the lithium battery 700, the relevant staff rotates the horizontal plate 634 to be magnetically attracted to the limit plate 635, so that the horizontal plate 634 and the longitudinal plate 633 are perpendicular. After the positioning device 600 is reset, the relevant staff rotates the horizontal plate 634 to be disengaged from the limit plate 635 and fit it with the longitudinal plate 633 to reduce space occupancy and provide more operating space for subsequent operations.

[0038] Specifically, if Figures 1 to 6 As shown, when the relevant staff assembles the lithium battery 700, first, the relevant staff rotates the horizontal plate 634 to the position where it is aligned with the limit plate 635, so that the horizontal plate 634 and the longitudinal plate 633 are perpendicular to each other.

[0039] Then the positioning device 600 is controlled to turn on, that is, by turning on the drive motor 640, the bidirectional screw 610 is rotated, and the two screw sliders 620 approach each other and drive the respective connected limiting structures 630 to approach. Then, the relevant staff arranges the lithium battery 700 between the two limiting structures 630, and after the arrangement is completed, the two positioning ends of the positioning device 600 are brought closer again to make the lithium battery 700 more compact.

[0040] Then the relevant staff performs preliminary winding on the upper area of ​​the lithium battery 700 to fix the multiple lithium batteries 700. Then the relevant staff resets the positioning device 600 and continues to wind the multiple lithium batteries 700. In the subsequent winding, the relevant staff can rotate the lithium battery 700 to make the rotating table 500 rotate accordingly, and after the winding is completed, the lithium battery 700 is pushed to the bottom of the working end of the spot welding machine 400.

[0041] Then, the relevant staff controls the driving cylinder 300 so that the driving cylinder 300 drives the working end of the spot welder 400 to perform spot welding operations on the lithium battery 700. The relevant staff displaces the lithium battery 700 so that the spot welder 400 performs spot welding on different positions of the lithium battery 700.

[0042] In one embodiment of the present invention, a slidable mounting bracket 301 is provided on the bracket 200 and is locked by a damping knob, wherein the driving cylinder 300 is provided on the mounting bracket 301 to facilitate adjustment of the electric welding position of the driving cylinder 300 and the spot welder 400.

[0043] In addition, a foot switch 302 is provided at the bottom of the workbench 100, and the foot switch 302 is connected to the driving cylinder 300 through a controller.

[0044] It should be noted that the relevant staff can use the foot switch 302 to drive the cylinder 300 to drive the working end of the spot welding machine 400 to descend and perform spot welding operations on the lithium battery 700, thereby allowing the relevant staff to use their hands and feet and improve work efficiency.

[0045] In one embodiment of the present invention, the rotating table 500 is arranged on the central axis of the workbench 100, and the two slide grooves 101 are symmetrically arranged on both sides of the rotating table 500, so that the operating space on both sides is the same when the lithium battery 700 is assembled.

[0046] In addition, an emergency stop switch is provided on the workbench 100, which is connected to the drive cylinder 300 and the drive motor 640 through a controller. Relevant staff can use the emergency stop switch to quickly shut down the drive cylinder 300 and the drive motor 640 to deal with emergencies.

[0047] In summary, according to the lithium battery assembly workbench of the embodiment of the present invention, the lithium battery 700 can be conveniently positioned and initially wound through the two positioning ends of the positioning device 600 to ensure the neatness and stability of the initial winding. After the initial winding is completed, the positioning device 600 is reset to make room for subsequent operations; the combined use of the driving cylinder 300 and the spot welding machine 400 not only reduces the subsequent transportation operations, but also ensures the stability and consistency during the welding process, thereby improving the work efficiency of the lithium battery 700 assembly.
