[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in 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.

[0021] like Figure 1-4 As shown, a lithium battery welding wire plate spot welding machine includes a workbench 1 and a lithium battery 17, a mounting plate 2 is slidably arranged on the upper surface of the workbench 1, a mounting side plate 3 is fixedly installed on the side of the mounting plate 2, and a fixing component for fixing the lithium battery 17 is arranged on the upper surfaces of the mounting plate 2 and the mounting side plate 3, an electric welder 4 is fixedly arranged on the upper surface of the workbench 1 and on the side of the mounting side plate 3, a placing plate 7 is slidably arranged on the upper surface of the workbench 1 and on the side of the mounting plate 2, and a moving component for driving the mounting plate 2 and the placing plate 7 to move is arranged on the side of the workbench 1.

[0022] The utility model places the lithium battery 17 inside the clamping plate 9, and then drives the rotating plate 14 to rotate through the operating rod 16, so that the rotating plate 14 contacts the outer arc surface of the lithium battery 17, thereby fixing the lithium battery 17 through the clamping plate 9 and the rotating plate 14, connecting the placement plate 7 with the mounting plate 2, and then welding the lithium battery 17 through the welding head 6, thereby avoiding the staff from holding the lithium battery 17 for spot welding, thereby protecting the staff and improving the spot welding efficiency.

[0023] Specifically, the fixing assembly includes a clamping plate 9, a connecting plate 13, a rotating plate 14 and an operating rod 16. The clamping plate 9 is fixedly mounted on the upper surface of the mounting plate 2, the connecting plate 13 is fixedly arranged on the upper surface of the mounting side plate 3, and the rotating plate 14 is rotatably arranged on the upper surface of the connecting plate 13, and the operating rod 16 is fixedly mounted on the upper surface of the rotating plate 14. In the above design, the clamping plate 9 and the connecting plate 13 are respectively fixed to the upper surfaces of the mounting plate 2 and the mounting side plate 3, and the clamping plate 9 and the connecting plate 13 are in contact. By operating the operating rod 16, the rotating plate 14 is driven to rotate on the upper surface of the connecting plate 13, so that the rotating plate 14 is in contact with the outer arc surface of the lithium battery 17 for clamping.

[0024] Specifically, the upper surface of the connecting plate 13 is set as an inclined surface, and the lower surface of the rotating plate 14 is set as an inclined surface corresponding to the upper surface of the connecting plate 13. The lithium battery 17 is set inside the clamping plate 9, and the rotating plate 14 contacts the outer arc surface of the lithium battery 17. The upper surface of the connecting plate 13 and the lower surface of the rotating plate 14 are both set as inclined surfaces inclined downward. With the above design, when the rotating plate 14 rotates from the side to the upper surface of the lithium battery 17, the rotating plate 14 will gradually contact the lithium battery 17 under the action of the inclined surface, so that the lithium battery 17 is clamped by the clamping plate 9 and the rotating plate 14, thereby achieving the effect of fixing the lithium battery 17.

[0025] Specifically, the moving assembly includes a servo motor 8, a screw rod 10 and a snap-on protrusion 12. There are two groups of snap-on protrusions 12, which are respectively fixedly mounted on the lower surface of the mounting plate 2 and the placement plate 7, and a snap-on groove 11 corresponding to the snap-on protrusion 12 is provided on the upper surface of the workbench 1. Both groups of snap-on protrusions 12 are configured as convex blocks. The above design ensures that the mounting plate 2 and the placement plate 7 can only move left and right along the snap-on groove 11 by snapping the two groups of snap-on protrusions 12 into the inside of the snap-on groove 11, thereby preventing the mounting plate 2 and the placement plate 7 from being separated from the inside of the snap-on groove 11.

[0026] Specifically, the servo motor 8 is bolted to the side of the workbench 1, and the screw 10 is keyed to the output end of the servo motor 8. The screw 10 is rotatably arranged inside the clamping groove 11, and the two sets of clamping protrusions 12 are both threadedly sleeved on the outer arc surface of the screw 10. In the above design, the servo motor 8 is started to drive the screw 10 to rotate, and the two sets of clamping protrusions 12 are threadedly connected to the screw 10. The screw 10 drives the two sets of clamping protrusions 12 to move inside the clamping groove 11 through the threads, thereby facilitating the fixed lithium battery 17 to be moved to the lower surface of the electric welding head 6.

[0027] Specifically, a support plate 18 is fixedly mounted on the side of the mounting plate 2, a spring plunger 19 is arranged inside the support plate 18, and a positioning hole 20 corresponding to the spring plunger 19 is opened on the side of the placement plate 7. The above design connects the placement plate 7 to the mounting plate 2 by inserting the spring plunger 19 into the positioning hole 20.

[0028] Specifically, a connecting hose 5 is provided on the side of the electric welder 4, and an electric welding head 6 is provided on the lower surface of the connecting hose 5, and a plurality of sets of plate placing grooves 15 are provided on the upper surface of the placing plate 7. The above design facilitates the staff to spot weld the plate placing groove 15 and the lithium battery 17 using the electric welding head 6 by placing the welding wire plate inside the plate placing groove 15, and the connecting hose 5 is set as a hose to facilitate the movement of the electric welding head 6.

[0029] Working principle: operate the operating lever 16 to rotate the rotating plate 14 to the side of the placement plate 7, then place the lithium battery 17 into the clamping plate 9, and then operate the operating lever 16 to drive the rotating plate 14 to rotate above the lithium battery 17, and the rotating plate 14 gradually contacts the upper surface of the lithium battery 17 during the rotation process, so that the lithium battery 17 is fixed by the clamping plate 9 and the rotating plate 14, and then the welding wire plate is placed in the corresponding plate placement slot 15, and the servo motor 8 drives the screw rod 10 to rotate to move the lithium battery 17 to the bottom of the electric welding head 6, and the staff then spot welds the lithium battery 17 through the electric welding head 6, so as to avoid the staff holding the lithium battery 17 for spot welding, thereby protecting the staff and improving the spot welding efficiency.
