Description

Technical Field

[0001] This invention relates to the field of welding technology, specifically to an ultrasonic welding device for collecting waste gas during power adapter production. Background Technology

[0002] Ultrasonic welding technology, as a highly efficient and clean connection process, has been widely used in the manufacturing of power adapters. As a key power supply component of electronic devices, the power adapter's housing, interfaces, and internal circuit board fixing structure all require welding for assembly. Ultrasonic welding, with its advantages of requiring no solder, short welding time, high joint strength, and minimal heat impact on the workpiece, has become a core process for connecting plastic housings to metal interfaces and splicing plastic components. With the large-scale development of the electronics manufacturing industry, power adapter production has formed an automated, assembly-line operation mode, and ultrasonic welding equipment is gradually being integrated into automated production lines. By equipping workpiece positioning fixtures, automatic feeding mechanisms, and welding parameter control systems, continuous and precise welding processes have been achieved.

[0003] Existing equipment has poor waste gas collection during welding, lacking an effective waste gas collection and purification system. Harmful gases and particles generated during welding are directly emitted into the workshop environment, posing a threat to the health of operators and potentially affecting welding quality, leading to defects on the product surface. Summary of the Invention

[0004] To solve the above technical problems, the present invention is implemented through the following technical solution: an ultrasonic welding device for collecting exhaust gas in power adapter production, comprising a workbench, a first support fixedly connected to the top of the workbench, an ultrasonic welding machine fixedly connected to the top of the first support, a welding head fixedly connected to the bottom of the ultrasonic welding machine, a protective device fixedly connected to the bottom of the ultrasonic welding machine, the welding head located inside the protective device, a first exhaust pipe connected to one side of the protective device, and an exhaust gas purification device fixedly connected to the portion of the top of the workbench located on one side of the first support. The end of the first exhaust pipe away from the protective device is connected to the exhaust gas purification device. A vacuum pump is fixedly connected to a portion of the exhaust gas purification device. A second vacuum pipe is connected to the top of the exhaust gas purification device, away from the first vacuum pipe. The end of the second vacuum pipe away from the exhaust gas purification device is connected to the air inlet of the vacuum pump. A clamping and fixing device is fixedly connected to the top of the workbench on one side of the first support. A vacuum tank is fixedly connected to the top of the workbench on one side of the clamping and fixing device. The outlets of the vacuum pump are connected to both sides of the vacuum tank. A connecting pipe is connected to the air inlet of the vacuum pump. The end of the connecting pipe away from the vacuum pump is connected to the clamping and fixing device. A second support is fixedly connected to the top of the workbench on one side of the clamping and fixing device. A high-pressure cooler is fixedly connected to the top of the second support.

[0005] Preferably, the clamping and fixing device includes a T-shaped base, a connecting frame fixedly connected to the top of the T-shaped base, two sets of T-shaped bases symmetrically distributed at the bottom of the connecting frame, a slide rail fixedly connected to the top of the connecting frame, a first sliding block and a second sliding block slidably connected to the inner wall of the slide rail, the first sliding block and the second sliding block being symmetrically arranged on the slide rail, a first clamping block fixedly connected to the top of the first sliding block, a second clamping block fixedly connected to the top of the second sliding block, a vacuum adsorption mechanism fixedly connected to the sides of both the first clamping block and the portion of the bottom of the connecting frame located between the two sets of T-shaped bases being rotatably connected to a gear, a first toothed rod meshing with the side of the gear, a second toothed rod meshing with the side of the gear away from the first toothed rod, the top of the first toothed rod being fixedly connected to the bottom of the first clamping block via a bracket, the top of the second toothed rod being fixedly connected to the bottom of the second clamping block via a bracket, a movable end of a hydraulic rod fixedly connected to one side of the second clamping block, the T-shaped base being fixedly connected to the top of the worktable, and the fixed end of the hydraulic rod being fixedly connected to the top of the worktable.

[0006] Preferably, the vacuum adsorption mechanism includes a vacuum adsorption clamping box, on which adsorption ports are evenly distributed on the side. A vacuum suction cup is fixedly connected to the inner wall of the adsorption port, and a first filter plate is fixedly connected to the side of the vacuum suction cup. The first filter plate has first filter holes evenly distributed on its side. The vacuum adsorption clamping box is fixedly connected to one side of a first clamping block and a second clamping block, respectively. The side of the vacuum adsorption clamping box is connected to a connecting pipe. After the clamping block fixes the adapter, the vacuum pump is started, and a negative pressure is formed in the vacuum adsorption clamping box through the connecting pipe. Under the action of negative pressure, the vacuum suction cup in the adsorption port tightly adsorbs the surface of the adapter, preventing it from shifting or shaking during welding. The first filter plate and filter holes can intercept small particles and exhaust gas generated during welding, preventing them from entering the vacuum system.

[0007] Preferably, the protective device includes a fixed protective cover with a telescopic groove at its bottom. A telescopic spring is fixedly connected to the top of the inner wall of the telescopic groove. The fixed end of an elastic telescopic rod is fixedly connected to the top of the inner wall of the telescopic groove, which is located inside the telescopic spring. A telescopic cover is fixedly connected to the movable end of the elastic telescopic rod. The top of the telescopic cover is fixedly connected to the telescopic spring. An annular inclined guide plate is fixedly connected to the inner wall of the fixed protective cover. The top of the fixed protective cover is fixedly connected to the bottom of the ultrasonic welding machine. The fixed protective cover is fitted over the welding head. The side of the fixed protective cover above the telescopic groove is connected to the first exhaust pipe. When the ultrasonic welding machine is started and the welding head is pressed down for welding, the telescopic cover is compressed by the reaction force of the adapter surface, compressing the telescopic spring and the elastic telescopic rod, and retracts upward into the telescopic groove. This adapts to different welding height requirements, ensuring that it always fits tightly against the working surface. The waste gas generated during welding is effectively collected. The annular inclined guide plate optimizes the waste gas path, allowing the waste gas to quickly enter the waste gas purification device through the first exhaust pipe.

[0008] Preferably, the exhaust gas purification device includes a third support, a purification cylinder is fixedly connected to the top of the third support, a drive motor is fixedly connected to one side of the purification cylinder, a rotating shaft is rotatably connected to the inner wall of the purification cylinder, the drive shaft of the drive motor passes through one side of the purification cylinder and is fixedly connected to the rotating shaft, a second filter plate is fixedly connected to the inner wall of the purification cylinder, second filter holes are evenly fixedly connected to the side of the second filter plate, the rotating shaft passes through the second filter plate and is rotatably connected to the second filter plate, a first connecting rod is evenly fixedly connected to the side of the rotating shaft located on one side of the second filter plate, a cleaning brush is evenly fixedly connected to the side of the first connecting rod, a recycling box is connected to the side of the purification cylinder located on one side of the second filter plate, activated carbon particles are evenly arranged on the inner wall of the purification cylinder located on one side of the second filter plate, a second connecting rod is evenly fixedly connected to the side of the rotating shaft located on one side of the second filter plate, and a stirring and lifting plate is evenly fixedly connected to the side of the second connecting rod.

[0009] Preferably, the third bracket is fixedly connected to the top of the workbench. The part of the top of the purification cylinder near the recovery box is connected to the first exhaust pipe, and the part of the top of the purification cylinder near the activated carbon particles is connected to the second exhaust pipe. When the exhaust pump is started, the exhaust gas enters the purification cylinder through the first exhaust pipe and is initially purified by the second filter plate. The drive motor drives the rotating shaft to rotate, and the cleaning brush on the first connecting rod cleans the surface of the second filter plate. Impurities fall into the recovery box. At the same time, the rotating shaft drives the second connecting rod to rotate, and the stirring plate agitates the activated carbon particles, so that they can fully contact the exhaust gas and adsorb harmful gases and small particles. The purified gas is discharged through the second exhaust pipe.

[0010] This invention provides an ultrasonic welding device for collecting waste gas during power adapter production. It has the following beneficial effects: 1. This power adapter manufacturing process utilizes an ultrasonic welding device that collects exhaust gas. Driven by a hydraulic rod and a gear and rack linkage structure, it can move the first and second clamping blocks synchronously in opposite directions. This allows it to adapt to power adapters of different specifications without changing the clamps, and eliminates the need to stop the machine to replace the clamping components, significantly saving changeover time and improving production efficiency.

[0011] 2. This power adapter manufacturing process incorporates an ultrasonic welding device capable of collecting exhaust gases. A vacuum pump creates negative pressure within the vacuum adsorption clamping box via a connecting pipe, causing the vacuum suction cup to tightly adhere to the power adapter surface. Compared to traditional mechanical clamping, the adsorption force is more uniform and acts on the entire contact surface, effectively preventing adapter displacement or shaking during welding and improving the accuracy of the weld point position. The first filter plate and first filter holes intercept tiny metal particles, welding slag, or exhaust gas impurities generated during welding, preventing them from entering the vacuum pipeline and causing blockages or damage to vacuum pump components, thus extending the service life of the vacuum system. Furthermore, the flexible clamping characteristics of vacuum adsorption do not leave clamp marks or scratches on the adapter surface, avoiding damage to the product's appearance and ensuring product quality.

[0012] 3. This power adapter is used in the production of ultrasonic welding devices that can collect waste gas. When the welding head is pressed down for welding, the telescopic cover will automatically retract into the telescopic groove due to the reaction force, compressing the telescopic spring and elastic telescopic rod. It can adapt to welding needs of different heights without manual adjustment, ensuring that the protective device is always in close contact with the working surface. This effectively blocks the sparks generated during welding, preventing burns to operators or ignition of surrounding materials. At the same time, it encloses the welding waste gas within the protective range, preventing the waste gas from escaping into the working environment. The annular inclined guide plate optimizes the waste gas flow path, guiding the waste gas into the first exhaust pipe quickly and smoothly, improving the waste gas collection efficiency, reducing the harm of waste gas to the operator's respiratory system, and maintaining a safe working environment.

[0013] 4. This power adapter manufactures an ultrasonic welding device for collecting waste gas. After the waste gas enters the purification cylinder, the second filter plate first intercepts larger particulate impurities, completing preliminary purification and preventing large particles from entering subsequent stages and affecting the activated carbon adsorption effect. The drive motor drives the rotating shaft to rotate, and the cleaning brush on the first connecting rod can clean the surface of the second filter plate in real time, brushing the attached impurities off into the collection box to prevent the filter plate from clogging and reduce maintenance downtime. At the same time, the stirring and lifting plate on the second connecting rod continuously stirs the activated carbon particles, breaking the static accumulation state of the activated carbon and allowing the waste gas to fully contact the activated carbon particles. Compared with static adsorption, this increases the contact area, significantly improving the adsorption efficiency for harmful gases and small particles, ensuring that the discharged gas meets the standards, further protecting the health of operators, and preventing waste gas from polluting the working environment.

The system includes a vacuum pump 10, and a second vacuum pipe 11 connected to the top of the exhaust gas purification device 9, away from the first vacuum pipe 8. One end of the second vacuum pipe 11, away from the exhaust gas purification device 9, is connected to the air inlet of the vacuum pump 10.

A second support 4 is fixedly connected to the top of the workbench 1, located on one side of the clamping and fixing device 12. The second bracket 4 has a high-pressure air cooler 5 fixedly connected to its top. The clamping and fixing device 12 includes a T-shaped base 121, with a connecting frame 122 fixedly connected to its top. Two sets of T-shaped bases 121 are symmetrically distributed at the bottom of the connecting frame 122. A slide rail 123 is fixedly connected to the top of the connecting frame 122. A first sliding block 124 and a second sliding block 125 are slidably connected to the inner wall of the slide rail 123. The first sliding block 124 and the second sliding block 125 are symmetrically arranged on the slide rail 123. A first clamping block 126 is fixedly connected to the top of the first sliding block 124, and a second clamping block 127 is fixedly connected to the top of the second sliding block 125. The first clamping block 126 and the second clamping block 127... Vacuum adsorption mechanisms 128 are fixedly connected to the sides. The bottom of the connecting frame 122, located between the two sets of T-shaped bases 121, is rotatably connected to a gear 129. A first toothed rod 1210 is meshed on the side of the gear 129. A second toothed rod 1211 is meshed on the side of the gear 129 away from the first toothed rod 1210.

[0018] In use, the power adapter is placed between the first clamping block 126 and the second clamping block 127 of the clamping and fixing device 12. The hydraulic rod 1212 is activated, and the movable end of the hydraulic rod 1212 pushes the second clamping block 127. The second clamping block 127 drives the gear 129 to rotate through the second rack 1211. The gear 129 then drives the first clamping block 126 through the first rack 1210, so that the first clamping block 126 and the second clamping block 127 move closer to each other. Due to the linkage of the gear 129, power adapters of different sizes can be clamped and fixed, improving the adaptability of the device.

[0019] For the second embodiment, please refer to... Figures 1-6 Based on the first embodiment, the present invention provides a technical solution: the vacuum adsorption mechanism 128 includes a vacuum adsorption clamping box 1281, the vacuum adsorption clamping box 1281 has adsorption ports 1282 evenly opened on its side, a vacuum suction cup 1283 is fixedly connected to the inner wall of the adsorption port 1282, a first filter plate 1284 is fixedly connected to the side of the vacuum suction cup 1283, a first filter hole 1285 is evenly opened on the side of the first filter plate 1284, the vacuum adsorption clamping box 1281 is fixedly connected to one side of the first clamping block 126 and the second clamping block 127 respectively, and the side of the vacuum adsorption clamping box 1281 is connected to the connecting pipe 15.

[0020] In use, after the first clamping block 126 and the second clamping block 127 clamp the power adapter, the vacuum pump 14 is started. Through the connecting pipe 15, a negative pressure environment is formed in the vacuum adsorption clamping box 1281 of the vacuum adsorption mechanism 128. At this time, the vacuum suction cup 1283 in the adsorption port 1282 will be tightly adsorbed on the surface of the power adapter, ensuring that there will be no displacement or shaking during the welding process.

At the same time, the vacuum adsorption method is gentler than the traditional mechanical clamping and will not damage the surface of the power adapter, ensuring the appearance quality of the product.

[0021] Third embodiment, please refer to Figures 1-7Based on the second embodiment, the present invention provides a technical solution: the protective device 7 includes a fixed protective cover 71, the bottom of the fixed protective cover 71 is provided with a telescopic groove 72, the top of the inner wall of the telescopic groove 72 is fixedly connected to a telescopic spring 73, the part of the top of the inner wall of the telescopic groove 72 located inside the telescopic spring 73 is fixedly connected to the fixed end of an elastic telescopic rod 74, the movable end of the elastic telescopic rod 74 is fixedly connected to a telescopic cover 75, the top of the telescopic cover 75 is fixedly connected to the telescopic spring 73, the inner wall of the fixed protective cover 71 is fixedly connected to an annular inclined guide plate 76, the top of the fixed protective cover 71 is fixedly connected to the bottom of the ultrasonic welding machine 3, the fixed protective cover 71 is sleeved on the outside of the welding head 6, and the part of the side of the fixed protective cover 71 located above the telescopic groove 72 is connected to the first exhaust pipe 8.

[0022] When the ultrasonic welding machine 3 is started and the welding head 6 is pressed down to perform welding operations, the telescopic cover 75 of the protective device 7 will compress the telescopic spring 73 and the elastic telescopic rod 74 due to the reaction force of the power adapter surface, and retract upward into the telescopic groove 72. This allows the protective device 7 to adapt to welding requirements at different heights, ensuring that the protective device 7 always fits tightly against the working surface, effectively collecting the exhaust gas generated during the welding process, and preventing the emission of fumes and the resulting sparks from causing injury to the operators. The annular inclined guide plate 76 further optimizes the exhaust gas collection path, allowing the exhaust gas to be guided more quickly and smoothly through the first exhaust pipe 8 to the exhaust gas purification device 9 for subsequent purification treatment, thereby maintaining the cleanliness and safety of the working environment.

[0023] For the fourth embodiment, please refer to [link / reference]. Figures 1-9Based on the third embodiment, the present invention provides a technical solution: the exhaust gas purification device 9 includes a third support 91, a purification cylinder 92 fixedly connected to the top of the third support 91, a drive motor 93 fixedly connected to one side of the purification cylinder 92, a rotating shaft 94 rotatably connected to the inner wall of the purification cylinder 92, the drive shaft of the drive motor 93 passing through one side of the purification cylinder 92 and fixedly connected to the rotating shaft 94, a second filter plate 95 fixedly connected to the inner wall of the purification cylinder 92, second filter holes 96 evenly fixedly connected to the side of the second filter plate 95, the rotating shaft 94 passing through the second filter plate 95 and rotatably connected to the second filter plate 95, and a first connecting rod evenly fixedly connected to the portion of the rotating shaft 94 located on one side of the second filter plate 95.

The side of the second connecting rod 910 is evenly fixedly connected to the stirring lifting plate 911. The third bracket 91 is fixedly connected to the top of the workbench 1. The part of the top of the purification cylinder 92 near the recovery box 98 is connected to the first exhaust pipe 8. The part of the top of the purification cylinder 92 near the activated carbon particles 99 is connected to the second exhaust pipe 11.

[0024] In use, the suction pump 10 is started. When the exhaust gas enters the purification cylinder 92 of the exhaust gas purification device 9 through the first suction pipe 8, it first passes through the second filter plate 95. The second filter holes 96 on the second filter plate 95 can effectively intercept larger particulate impurities in the exhaust gas, preventing them from entering subsequent purification stages and affecting the purification effect, thus performing preliminary cleaning treatment. Meanwhile, the rotating shaft 94 rotates continuously under the drive of the drive motor 93, and the cleaning brush 97 on the first connecting rod 912 continuously sweeps the surface of the second filter plate 95, promptly brushing off the impurities attached to it into the collection box 98 to prevent them from being discharged into the second filter plate 95. The second filter plate 95 is blocked to ensure its filtration function remains stable. At the same time, the rotating shaft 94 drives the second connecting rod 910 to rotate. The stirring and lifting plate 911 on the second connecting rod 910 continuously stirs the activated carbon particles 99 in the purification cylinder 92, so that the activated carbon particles 99 can fully contact the waste gas and more effectively adsorb harmful gases and fine particles in the waste gas, further purifying the waste gas. The gas purified by the activated carbon particles 99 is discharged through the second exhaust pipe 11, thereby achieving efficient purification of the waste gas generated during the welding process and ensuring the air quality of the working environment.

[0025] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention.
