[0002] Sodium-ion batteries are widely used in energy storage, low-speed new energy vehicles, and backup power supplies due to their advantages such as abundant resources, low cost, high safety, and excellent low-temperature performance. Welding is a core process in the production and processing of sodium-ion batteries. It is mainly used for the fixed connection between battery tabs and current collectors, battery caps and casings, and cell connectors. The quality of welding directly determines the battery's conductivity, sealing performance, and service life.

Furthermore, the welding process generates welding fumes and harmful gases. The main component of welding fumes is particulate matter, with the possibility of small amounts of organic waste gas. If these welding fumes are emitted directly without treatment, they not only pollute the workshop environment and endanger the health of operators but may also affect the cleanliness of the welding area, thereby reducing welding quality.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-6 The present invention provides the following technical solution: a welding device for processing sodium-ion batteries, comprising a welding device body 1, a support frame 2 fixedly connected above the welding device body 1, a lifting electric telescopic rod 3 fixedly connected in the middle of the support frame 2, a longitudinal electric slide 4 fixedly connected at the output end of the lifting electric telescopic rod 3 for adjusting the longitudinal position of the welding head 7, a transverse electric slide 5 fixedly connected at the sliding end of the longitudinal electric slide 4 for adjusting the transverse position of the welding head 7, a connecting block 6 fixedly connected at the sliding end of the transverse electric slide 5, a welding head 7 fixedly connected below the connecting block 6, a purification component 8 provided at one end above the support frame 2 for purifying the welding exhaust gas, and a limit component 9 provided in the middle above the welding device body 1 for limiting the sodium-ion batteries of different specifications.

[0029] Please see Figure 3The purification assembly 8 includes a purification box 81 with a purification chamber inside. The purification box 81 is fixedly connected to the top of the support frame 2. One end of the purification box 81 is fixedly connected to a connecting pipe 82, and one end of the connecting pipe 82 is fixedly connected to an exhaust fan 84 to generate suction. The other end of the purification box 81 is fixedly connected to a suction pipe 83, one end of the suction pipe 83 is fixedly connected to a flexible hose 85, and one end of the flexible hose 85 is fixedly connected to a suction hood 86. The suction hood 86 facilitates the suction of exhaust gas, which then enters the purification box 81 through the flexible hose 85 and the suction pipe 83. Purification is carried out in the process. A connecting rod 87 is fixedly connected to the top of the suction hood 86. The top of the connecting rod 87 is fixedly connected to the connecting block 6. The interior of the purification box 81 is equipped with multi-stage purification components 88, which facilitates multi-stage purification of exhaust gas and makes the purification effect better. A disassembly cover 80 is provided on the top of the purification box 81 to facilitate sealing the top of the purification box 81. A rubber sealing gasket is fixedly connected to the bottom of the disassembly cover 80 to seal the mounting surface. The disassembly cover 80 and the purification box 81 are limited by the fixing component 89, which makes it easy to disassemble and assemble the disassembly cover 80.

[0030] Please see Figure 3 The two ends of the disassembly cover 80 are symmetrically and fixedly connected with positioning rods. The upper part of the purification box 81 is symmetrically provided with positioning holes that are adapted to the positioning rods. The positioning rods and positioning holes are tightly inserted to facilitate positioning when the disassembly cover 80 is installed.

[0031] Please see Figure 3 A handle is fixedly connected in the middle above the disassembly cover 80, making it easy to take off and put on the disassembly cover 80.

[0032] Please see Figure 4 The multi-stage purification component 88 includes a positioning seat 881, which is symmetrically and fixedly connected inside the multi-stage purification component 88. Inside the purification box 81, a primary filter cotton 882, a high-efficiency activated carbon filter 883, and a HEPA high-efficiency filter 884 are sequentially inserted through the positioning seat 881. The primary filter cotton 882 facilitates the filtration of large particulate dust in the exhaust gas. The high-efficiency activated carbon filter 883 and the HEPA high-efficiency filter 884 work together to facilitate the adsorption of harmful gases and the precise interception of ultrafine dust, respectively.

[0033] Please see Figure 4 A flow guide plate 885 is distributed between the primary filter cotton 882 and the high-efficiency activated carbon filter 883. The flow guide plate 885 is distributed in an alternating manner, and one end of the flow guide plate 885 is fixedly connected to the purification box 81 to facilitate the flow of exhaust gas. UV lamp tubes 886 are distributed and fixedly connected on both sides of the flow guide plate 885 to facilitate photolysis of waste.

[0034] Please see Figure 4The purification box 81 is equipped with plasma generators 887 symmetrically installed at one end, which effectively settles trace suspended particles in the airflow, neutralizes static electricity in the flue gas, eliminates residual odors, and achieves fresh and purified air.

[0035] Please see Figure 5 The fixing assembly 89 includes a fixed electric telescopic rod 891, which is fixedly connected to both sides of the purification box 81. The output end of the fixed electric telescopic rod 891 is rotatably connected to a rotating seat 892. One end of the rotating seat 892 is fixedly connected to a fixing plate 893. The lower part of the fixing plate 893 is rotatably connected to a rotating seat 894, and the lower end of the rotating seat 894 is fixedly connected to the fixed electric telescopic rod 891. In use, the telescopic end of the fixed electric telescopic rod 891 rises, thereby driving the fixing plate 893 to open under the action of the rotating seat 892 and the rotating seat 894, releasing the restriction on the disassembly cover 80, so that the disassembly cover 80 can be removed to clean and maintain the internal multi-stage purification components 88.

[0036] Please see Figure 6 The limiting component 9 includes a support base 91 with a square groove inside. The support base 91 is fixedly connected to the middle of the upper part of the welding device body 1. A bidirectional trapezoidal lead screw 93 is rotatably connected to the inside of the support base 91 via a bearing. A servo motor 92 is fixedly connected to one end of the bidirectional trapezoidal lead screw 93. The surface of the bidirectional trapezoidal lead screw 93 is symmetrical and threaded with transverse square sliders 94. When the servo motor 92 is working, it drives the bidirectional trapezoidal lead screw 93 to rotate, which facilitates the movement of the two transverse square sliders 94. A limiting seat 95 is fixedly connected above the transverse square sliders 94, so that the movement of the transverse square sliders 94 drives the limiting seat 95 to adjust its position. The limiting seat 95 and the support base 91 are slidably connected. The inside of the limiting seat 95... The device features a square sliding groove. Inside the limiting seat 95, a bidirectional trapezoidal lead screw 97 is rotatably connected via bearings. One end of the bidirectional trapezoidal lead screw 97 is fixedly connected to a servo motor 96, which is a forward and reverse motor. The surface of the limiting seat 95 is symmetrically connected to a longitudinal square slider 98 via threads. One end of the longitudinal square slider 98 is fixedly connected to a limiting plate 99. The servo motor 96 drives the bidirectional trapezoidal lead screw 97 to rotate, facilitating the movement of the longitudinal square slider 98, which in turn moves the limiting plate 99. This allows the device to accommodate sodium-ion batteries of different lengths and widths for fixation. In use, the sodium-ion battery placed in the frame is placed on the support base 91, and then the limiting groove formed by the limiting seat 95 and the limiting plate 99 limits the sodium-ion battery.

[0037] Please see Figure 6The horizontal square slider 94 and the support base 91 are fitted together and slidably connected, and the vertical square slider 98 and the limiting base 95 are fitted together and slidably connected, which facilitates the guidance and limiting of the movement of the horizontal square slider 94 and the vertical square slider 98.

[0038] Please see Figure 6 A stop block is fixedly connected in the middle of the two-way trapezoidal lead screw 97 to facilitate limiting the movement range of the longitudinal square slider 98 on the two-way trapezoidal lead screw 97.

[0039] The working principle and usage process of this invention are as follows: In use, the sodium-ion battery to be welded is placed on the support base 91. The servo motor 92 is started, driving the bidirectional trapezoidal lead screw 93 to rotate. The positive and negative threads on the surface of the bidirectional trapezoidal lead screw 93 drive two transverse square sliders 94 to slide towards or away from each other along the support base 91, thereby causing the limiting seat 95 to move laterally to accommodate the width of the battery. Simultaneously, the servo motor 96 is started, driving the bidirectional trapezoidal lead screw 97 to rotate. The bidirectional trapezoidal lead screw 97 drives two longitudinal square sliders 98 to slide towards or away from each other along the limiting seat 95, thereby causing the limiting plate 99 to move longitudinally to accommodate the length of the battery. Through bidirectional adjustment in both the transverse and longitudinal directions, the limiting seat 95 and the limiting plate 99 together form a limiting groove that matches the shape of the battery, achieving precise positioning and clamping of sodium-ion batteries of different lengths and widths.

[0040] During welding, the lifting electric telescopic rod 3 drives the welding head 7 to rise and fall to adjust the welding height. The longitudinal electric slide 4 and the transverse electric slide 5 drive the welding head 7 to move longitudinally and laterally, respectively, so as to achieve precise positioning and movement of the welding head 7 at any position in the plane, thereby meeting the needs of different welding trajectories and multi-point welding.

[0041] During the welding process, the exhaust fan 84 generates negative pressure suction, which draws in the exhaust gas generated in the welding area through the suction hood 86. The suction hood 86 is fixedly connected to the connecting block 6 via the connecting rod 87, so the suction hood 86 can move synchronously with the welding head 7, always facing the welding position, ensuring the immediate and accurate collection of welding exhaust gas.

[0042] The collected exhaust gas enters the purification chamber 81 sequentially through hose 85 and suction pipe 83. Inside the purification chamber 81, the exhaust gas first passes through primary filter cotton 882 to remove large dust particles; then it enters the guide plate area 885, where the staggered distribution of the guide plates 885 extends the flow path of the exhaust gas, increasing the contact time between the exhaust gas and the UV lamp tube 886, which performs photolysis treatment on the organic pollutants in the exhaust gas. Next, the exhaust gas passes sequentially through high-efficiency activated carbon filter 883 and HEPA high-efficiency filter 884, respectively adsorbing harmful gases and precisely trapping ultrafine dust. Finally, the plasma generator 887 further purifies the treated gas, effectively settling trace suspended particles in the airflow, neutralizing static electricity in the flue gas, and eliminating residual odors. The purified clean gas is discharged through connecting pipe 82.

[0043] When it is necessary to clean or replace the multi-stage purification components 88, the fixed electric telescopic rod 891 is activated, and its telescopic end rises. Through the linkage of rotating seat one 892 and rotating seat two 894, the fixed plate 893 is opened, releasing the restriction on the disassembly cover 80. The operator can then remove the disassembly cover 80 using the handle to clean or replace the pre-filter cotton 882, high-efficiency activated carbon filter 883, and HEPA high-efficiency filter 884 inside the purification box 81, making maintenance convenient.

[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
