[0001] This invention relates to the field of automatic welding machines, and in particular to an automatic welding machine for aluminum-cased lithium batteries. Background Technology

[0002] Aluminum-cased lithium batteries are currently the mainstream type of liquid lithium batteries and are used in almost all fields related to lithium batteries. During the production of aluminum-cased lithium batteries, the outer shell is made of aluminum. During manufacturing, the outer shell of the aluminum shell needs to be sealed and welded to prevent water from soaking into the internal lithium battery. An automatic welding machine is required when sealing and welding the outer shell of the aluminum-cased lithium battery.

[0003] During use, existing automatic welding machines can move the welding torch automatically to achieve automated welding. However, most of these machines cannot handle welding slag, which splashes onto the work area, causing clutter. Additionally, when welding aluminum shells, the welding torch cannot clean the weld seam dust, affecting the welding effect. Summary of the Invention

This prevents dust or particles from affecting the welding quality, thus solving the problem that most automatic welding machines cannot effectively handle welding slag, which splatters in the work area, causing clutter and potentially falling into the welding gaps of the workpiece, impacting the welding result. This system integrates welding fume and slag treatment, preventing slag splatter and blockages in the fume duct. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Example 1, referring to Figures 1 to 8This is the first embodiment of the present invention, which provides an automatic welding machine for aluminum-cased lithium batteries. It effectively prevents welding slag from splashing, prevents fumes from escaping, and prevents welding slag from entering the negative pressure pipe 212 and causing blockage. The machine includes a support mechanism comprising a multi-directional moving platform 110, a welding torch 120 mounted on the multi-directional moving platform 110, a mounting cover 130 mounted outside the welding torch 120, a bearing groove on the mounting cover 130, a lifting ring 140 within the bearing groove, and a telescopic spring 150 mounted on the lifting ring; and a fume and slag treatment unit. The components include a negative pressure assembly 210 disposed within the mounting cover 130, a filter assembly 220 disposed on the negative pressure assembly 210, a cleaning assembly 230 disposed within the mounting cover 130, and a disassembly assembly 240 disposed on the cleaning assembly 230; the anti-clogging component includes a guide assembly 310 disposed on the mounting cover 130, a magnetic suction assembly 320 disposed on the guide assembly 310, and a hole cleaning assembly 330 disposed on the guide assembly 310; the crevice cleaning component includes an adjustment assembly 410 disposed on the mounting cover 130, and a cleaning assembly 420 disposed on the adjustment assembly 410.

[0029] Specifically, the multi-directional moving platform 110 here can be a robotic arm or a combination of multiple electric slide rails 411. The method is not unique, as long as it meets the requirements of multi-directional movement during welding by the welding torch 120. The inner and outer walls of the lifting ring 140 are provided with arc edges. When it abuts against the welded protrusion, the lifting ring 140 can move upward, causing the telescopic spring 150 to compress. Thus, when the mounting cover 130 moves, the movement of the mounting cover 130 will not be affected by the welded protrusion. The welding torch 120 here can be a laser welding torch 120 or a regular welding torch 120.

[0030] Furthermore, the negative pressure assembly 210 includes an installation cavity 211 disposed within the installation cover 130, and a negative pressure pipe 212 is connected to the installation cavity 211; the filter assembly 220 includes a plurality of openings 221 disposed on the inner wall of the installation cavity 211, and a circular frame is fixedly connected to each of the plurality of openings 221, and a metal filter screen 222 is disposed in each of the plurality of circular frames.

[0031] The negative pressure pipe 212 is connected to a negative pressure fan, which can provide sufficient air pressure for the extraction of smoke and dust. The outlet of the negative pressure fan can be connected to a flue gas treatment device for centralized treatment of the flue gas. The treatment of the exhaust gas here is existing technology and will not be described in detail here.

[0032] Preferably, the cleaning component 230 includes a micro motor 231 fixedly connected to the mounting cover 130. The mounting cover 130 has a T-shaped annular groove 232. A ring is rotatably connected to the annular groove 232. A gear ring 233 is fixedly connected to the ring. An extension groove 234 is provided on the inner wall of the annular groove 232. The mounting cover 130 has a vertical groove communicating with the extension groove 234. The output shaft of the micro motor 231 passes through the vertical groove and is fixedly connected to a gear 235 that meshes with the gear ring 233. An adapter block 236 is fixedly connected to the ring. A U-shaped scraper 237 for scraping the inner wall of the mounting cover 130 is fixedly connected to the adapter block 236. The disassembly component 240 includes a stop ring 241 fixedly connected to the mounting cover 130. The stop ring 241 has a notch 242 that mates with the U-shaped scraper 237.

[0033] It should be noted that the annular groove 232 is designed to guide the toothed ring 233 and prevent it from shifting. The U-shaped scraper 237 has an inclined surface to scrape the welding slag on the inner wall of the mounting cover 130. The stop ring 241 is designed to cooperate with the U-shaped scraper 237 to form a storage area for storing some of the welding slag.

[0034] During use, welding produces slag and fumes. The negative pressure pipe 212 generates negative pressure, creating negative pressure within the mounting cavity 211. This negative pressure, combined with multiple openings 221, allows for the absorption of fumes. Welding slag splashes during welding are also deflected towards the openings 221 under the negative pressure. Due to the metal filter 222, welding slag does not enter the negative pressure pipe 212, preventing blockage. The welding slag adheres to the side wall of the mounting cover 130 or the metal filter 222, preventing it from splashing onto the welding area and maintaining its cleanliness. When cleaning the inner wall of the mounting cover 130 is required, simply start the micro motor 231. The output shaft of the micro motor 231 rotates, driving the gear 235 to rotate, which in turn drives the gear ring 233 to rotate. This rotation is achieved through the adapter block 236. The U-shaped scraper 237 rotates to scrape the inner wall of the mounting cover 130 and the metal filter screen 222. At this time, the upper part of the welding slag on the inner wall of the mounting cover 130 falls vertically. It is worth noting that when cleaning welding slag, a collection tray can be placed at the lower end of the mounting cover 130 to collect the welding slag. The adapter block 236, U-shaped scraper 237 and stop ring 241 are combined to form a storage area. A small part of the welding slag can enter the storage area, and some welding slag falls directly into the stop ring 241. Then, with the push of the U-shaped scraper 237, it moves towards the notch 242. When it rotates one revolution, the U-shaped scraper 237 and the notch 242 are directly opposite each other. At this time, the lower end of the U-shaped scraper 237 is open, which allows some of the scraped welding slag to fall off, thereby cleaning the welding slag.

[0035] In summary, the fume and slag treatment components can treat welding fumes during the welding process, while also preventing welding slag from splashing into the processing area. Furthermore, during the fume treatment process, welding slag can be prevented from entering the negative pressure pipe 212, thus avoiding blockage of the negative pressure pipe 212.

[0036] Example 2, refer to Figures 1 to 8 This is the second embodiment of the present invention. Unlike the previous embodiment, this embodiment provides an anti-clogging component for an automatic welding machine for aluminum-cased lithium batteries, solving the problem of how to prevent the metal filter screen 222 from clogging and affecting the dust treatment. Its guide component 310 includes multiple cylinders 311 fixedly connected in the mounting cavity 211. A cylinder 312 is slidably connected in the cylinder 311. The cylinder 312 is elastically connected to the inner wall of the cylinder 312 by a spring 313. The magnetic suction component 320 includes a first magnet 321 fixedly connected to the cylinder 312. Multiple second magnets 322 that attract each other to the first magnet 321 are fixedly connected to the U-shaped scraper 237. The hole cleaning component 330 includes a disc 331 disposed in the mounting cavity 211. A connecting post 332 fixed to the cylinder 312 is fixedly connected to the disc 331. The disc 331 is provided with multiple hole cleaning needles 333 that cooperate with the metal filter screen 222.

[0037] Specifically, the attraction between the first magnet 321 and the second magnet 322 is greater than the elasticity of the spring 313. The cylinder 312 slides inside the cylinder 311 to guide the cylinder 312. The cleaning needle 333 pushes against the filter holes of the metal filter screen 222 in the opposite direction to clean the filter holes of the metal filter screen 222.

[0038] During use, when the U-shaped scraper 237 rotates around the inner wall of the mounting cover 130, the first magnet 321 and the second magnet 322 on the U-shaped scraper 237 attract each other, causing the cylinder 312 to move towards the first magnet 321, thereby causing the connecting column 332 to move towards the first magnet 321, and then the disc 331 to move towards the metal filter screen 222, thereby causing the cleaning needle 333 to move towards the metal filter screen 222 to clean the metal filter screen 222, preventing the metal filter screen 222 from becoming clogged and affecting the extraction of flue gas. It should be noted that the disc 331 is designed to block small particles of welding slag when they pass through the metal filter screen 222, preventing welding slag from entering the negative pressure pipe 212, and further preventing the negative pressure pipe 212 from becoming clogged.

[0039] In summary, by setting up anti-clogging components, when the U-shaped scraper 237 rotates around the inner wall of the mounting cover 130 to clean the inner wall of the mounting cover 130, the first magnet 321 and the second magnet 322 can also cooperate to drive the cleaning hole to cooperate with the filter hole of the metal filter screen 222 to clean the metal filter screen 222.

[0040] Example 3, referring to Figures 1-9 This is the third embodiment of the present invention. Unlike the previous embodiment, this embodiment provides a gap cleaning component for an automatic welding machine for aluminum-cased lithium batteries, which solves the problem of how to clean gaps during welding. It includes an adjustment component 410, which includes an annular electric slide rail 411 fixedly connected to the mounting cover 130. An extension plate 412 is slidably connected to the electric slide rail 411. The extension plate 412 has a through-hole, and a vertical plate 413 is slidably connected inside the through-hole. A fastening bolt 414 that cooperates with the vertical plate 413 is threadedly connected to the extension plate 412. The cleaning component 420 includes a horizontal plate 421 fixedly connected to the vertical plate 413. A brush 422 is provided on the horizontal plate 421. A dust suction pipe 423 that communicates with the negative pressure pipe 212 is fixedly connected to the horizontal plate 421.

[0041] Specifically, the electric slide rail 411 allows the extension plate 412 to rotate for cleaning at different angles, and the fastening bolt 414 secures the vertical plate 413 to prevent it from loosening.

[0042] During use, the welding torch 120 can move. Rotating the fastening bolt 414 loosens the vertical plate 413, allowing it to move up and down. This causes the brush 422 to move up and down, adjusting it to the desired position. As the welding torch 120 moves, the brush 422 contacts the gaps in the workpiece and the weld surface, loosening particles in the gaps and cleaning them from left to right. Then, the suction pipe 423 sucks away the particles or dust from above, preventing them from escaping from the gaps in the workpiece. Dust or foreign objects can affect the welding quality. It is worth noting that the workpiece to be processed here is the outer shell of an aluminum-cased lithium battery. Therefore, the welding torch 120 moves horizontally back and forth and left and right, so that the welding seam is curved and the brush 422 will not get stuck in the welding seam. This avoids the welding torch 120 from getting stuck. There is a gap between the dust suction pipe 423 and the lower end face of the horizontal plate 421 to avoid wear between the dust suction pipe 423 and the workpiece to be processed. The dust suction pipe 423 is connected to the negative pressure pipe 212 to ensure that there is enough suction to pick up foreign objects or dust in the gap and ensure the welding quality.

[0043] In summary, by setting up a gap cleaning component, the brush 422 on the outside of the mounting cover 130 can also clean the welding gap and suck up the welding dust during the welding process of the welding torch 120, thereby ensuring the cleanliness of the welding seam and preventing dust and other particles from affecting the welding quality.

[0044] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
