[0019] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: an auxiliary welding device for processing new energy lithium batteries, comprising a welding table 1, a groove 9 is provided on the welding table 1, and a plurality of guide rollers 10 are provided in the groove 9. Due to the guide rollers 10, the lithium battery can move on the guide rollers 10, thereby reducing friction and facilitating the movement of the lithium battery;

[0021] A welding bracket 2 is provided on the welding table 1, and a welding assembly 3 is installed on the welding bracket 2. Two sliding frames 4 are provided below the welding assembly 3. The two sliding frames 4 are respectively located on both sides of the welding table 1. A support assembly 7 is provided in the sliding frame 4. The support assembly 7 includes a sliding frame 701. A spring 703 is provided in the sliding frame 701. The other end of the spring 703 is fixedly connected to the inner wall of the sliding frame 4. Since the spring 703 is provided, the sliding frame 701 is supported by the elastic force of the spring 703, so that the sliding frame 701 drives the support roller 702 to extend outward. At the same time, the sliding frame 701 drives the gear 801 and the connecting plate 803 to rotate through the teeth 704, so that the support roller 702 and the pressure roller 804 can be quickly returned to their positions, so as to facilitate the re-fixation of the lithium battery;

[0022] The sliding frame 701 is disposed throughout the sliding frame 4. Two supporting rollers 702 are fixed on one side of the sliding frame 701. A plurality of teeth 704 are disposed on both sides of the sliding frame 701. The teeth 704 are meshedly connected with the side stopper assembly 8.

[0023] The side block assembly 8 includes a gear 801, which meshes with the teeth 704. A rotating shaft 802 is clamped in the middle of the gear 801. The rotating shaft 802 is arranged in the sliding frame 4. Connecting plates 803 are clamped on both sides of the rotating shaft 802. The other ends of the two connecting plates 803 are provided with pressure rollers 804. The connecting plates 803 are arc-shaped.

[0024] An adjustment assembly 6 is provided at the bottom of the two sliding frames 4, and the adjustment assembly 6 is installed in the welding table 1. The adjustment assembly 6 includes a multi-stage electric push rod 601, and the multi-stage electric push rod 601 is installed inside the welding table 1. Slide blocks 602 are fixed to both ends of the multi-stage electric push rod 601, and the slide blocks 602 are fixed to the bottom of the sliding frame 4. Because the multi-stage electric push rod 601 is provided, the multi-stage electric push rod 601 can drive the two sliding frames 4 to move through the slide blocks 602, so that the pressure roller 804 and the support roller 702 on the sliding frame 4 move synchronously, thereby improving the stability of the lithium battery clamping;

[0025] Slideways 5 are respectively provided on both sides of the welding table 1, and the slider 602 is slidably connected in the slideways 5. The slider 602 and the slideway 5 are both T-shaped. Because of the slideway 5, the slideway 5 supports and limits the slider 602, and the slider 602 will not separate from the slideway 5, thereby ensuring the stability of the movement of the sliding frame 4.

[0026] The working principle of the utility model is:

[0027] When in use, the lithium battery is mounted on the welding table 1 so that the lithium battery is located between the two sliding frames 4. The multi-stage electric push rod 601 is controlled to contract so that it drives the two sliding frames 4 to approach each other through the two sliders 602. When the support roller 702 contacts one side of the lithium battery, the support roller 702 is pressed to drive the sliding frame 701 to slide in the sliding frame 4. The teeth 704 drive the two connecting plates 803 to rotate through the gear 801, so that the pressure rollers 804 on the two connecting plates 803 on the same side approach each other until the pressure rollers 804 contact the front and rear sides of the lithium battery. At this time, the pressure rollers 804 can push the lithium battery for correction, and the control The welding assembly 3 is capable of welding lithium batteries. When the welding work is completed, the multi-stage electric push rod 601 drives the two sliding frames 4 to move away from each other through the two sliders 602, so that the support roller 702 and the pressure roller 804 gradually separate from the lithium battery. During this process, the sliding frame 701 is supported by the elastic force of the spring 703, so that the sliding frame 701 drives the support roller 702 to extend outward. At the same time, the sliding frame 701 drives the gear 801 and the connecting plate 803 to rotate through the teeth 704, so that the pressure roller 804 on the connecting plate 803 separates from the lithium battery, and the lithium battery is pushed to move on the guide roller 10 to be removed.
