The micro-beam plasma arc welding torch 534 is mounted at the bottom output end of the fine-tuning cylinder 5332. A gearbox 5333 is fixedly connected to one side of the angle-adjusting base 5331. A fourth motor 5334 is located on the outside of the gearbox 5333. The output end of the fourth motor 5334 drives the fine-tuning cylinder 5332 to adjust the angle through the gearbox 5333. During the application of this device, the lifting cylinder 531, the circumferential position adjustment group 532, and the angle adjustment group 533 work together to adjust the vertical working height of the micro-beam plasma arc welding torch 534 by means of the extension and retraction of the lifting cylinder 531. The vertical working range of the welding operation can be adjusted according to the actual placement position of the workpiece. The second motor 532 inside the circumferential position adjustment group 532... 2. The adjustment guide rail 5323 rotates as a whole, changing the position of the slider 5325 and thus switching the lateral working direction of the micro-beam plasma arc welding gun 534. The third motor 5326 drives the lead screw 5324 to rotate, driving the slider 5325 to slide inside the adjustment guide rail 5323. This allows for further fine-tuning of the horizontal working position of the micro-beam plasma arc welding gun 534.

During the application of this device, the fixing plate 31, mounting plate 32, bearing plate 33 and clamping electric cylinder 35 cooperate with each other, so that the device can be completed by relying on the screw assembly structure of the fixing plate 31. The entire fixture module 3 can be disassembled and replaced to adapt the clamping structure to different specifications of surface mount component terminals. The bearing plate 33 can stably place the workpiece to be processed.

[0024] Please refer to Figures 1-7The purification module 56 includes a purification component 561, a transmission component 562, and an anti-blocking component 563. The purification component 561 is installed on one side of the arc welding box 51, and its input end extends into both sides inside the arc welding box 51. The transmission component 562 is movably installed on the side of the arc welding box 51 away from the first motor 4. The anti-blocking component 563 is movably installed on the suction end of the purification component 561 and is connected to the end of a transmission shaft in the conveyor table 2 via the transmission component 562 to obtain power. The purification component 561 includes a purification box 5611, which is fixedly connected to the side of the arc welding box 51 away from the conveyor frame 1. A negative pressure fan 5612 is fixedly connected to one side of the purification box 5611. The input end of the negative pressure fan 5612 is connected to the inside of the purification box 5611.

An anti-clogging component 563 is rotatably connected to the arc-shaped filter screen 5615. A slot is provided on the outer side of the dust removal and receiving frame 5617. During the application of this device, it is constructed by setting up the purification component 561, the transmission component 562 and the anti-clogging component 563. The complete purification module 56 allows the power of the conveyor 2 to provide a driving force for the entire anti-clogging structure during use, eliminating the need for a separate drive structure to complete synchronous dust removal. It can continuously carry out fume purification and filter cleaning work in accordance with the welding process rhythm of the equipment. The negative pressure fan 5612 inside the purification module 561 generates negative pressure suction, which can uniformly draw the welding fumes generated by spot welding operations inside the arc welding box 51 into the purification box 5611. The suction hood 5614 can concentrate and gather the fume airflow, and together with the arc-shaped filter screen... The 5615 filter intercepts and filters particulate impurities inside the fumes. The purification core further purifies the filtered fumes, which are then transported through an external pipeline to an external purification system for further treatment. This system continuously handles pollutants generated during plasma arc welding. The transmission component 562 drives the transmission shaft of the conveyor 2 to continuously operate the anti-clogging component 563, which cleans the accumulated impurities on the surface of the arc-shaped filter screen 5615 in real time. The cleaned impurities fall directly into the cleaning and receiving frame 5617 below. Workers can remove the cleaning and receiving frame 5617 from the side slot 5616 using a slot to clean the waste residue. The detachable structure of the sealed maintenance cover 5613 allows workers to easily disassemble and replace the purification core, maintaining the permeability of the purification module 56 and preventing impurities from accumulating and causing blockages. This effectively reduces the frequency of equipment downtime for maintenance, ensuring continuous operation of automatic and semi-automatic electric arc and plasma arc welding machines, and effectively improving the fume treatment capacity and long-term operation effect of plasma arc welding equipment in the high-end intelligent manufacturing equipment industry. ;

[0025] Please refer to Figures 1-7The transmission assembly 562 includes a first synchronous pulley 5621, a second synchronous pulley 5622, and a third synchronous pulley 5623. The first synchronous pulley 5621 is rotatably connected to both ends of the arc welding box 51 on the side away from the negative pressure fan 5612. The two first synchronous pulleys 5621 are connected by a synchronous belt. The first synchronous pulley 5621 is connected to one end of the anti-blocking assembly 563 via a coupling. The second synchronous pulley 5622 is fixedly connected to the outside of one of the first synchronous pulleys 5621. The third synchronous pulley 5623 is rotatably connected to the side of the conveyor frame 1 away from the first motor 4. The third synchronous pulley 5623 is connected to the end of a transmission shaft inside the conveyor table 2 via a coupling. The third synchronous pulley 5623 and the second synchronous pulley 5622 are driven by a synchronous belt. The connection and anti-clogging component 563 includes a rotating main shaft 5631, which is rotatably connected to the inside of the arc-shaped filter screen 5615. A mounting side bracket 5632 is fixedly connected to the outer surface of the rotating main shaft 5631 in a ring at equal intervals. An anti-clogging cleaning brush plate 5633 is detachably mounted on the outer side of the mounting side bracket 5632 via screws. The cleaning end face of the anti-clogging cleaning brush plate 5633 is in contact with the filter surface of the arc-shaped filter screen 5615. The end of the rotating main shaft 5631 is connected to the first synchronous pulley 5621 via a coupling. During application, this device, by setting the first synchronous pulley 5621, the second synchronous pulley 5622, the third synchronous pulley 5623, and the synchronous belt, forms a complete transmission component 562, enabling it to be used... The power output from the drive shaft of the auxiliary conveyor 2 drives the third synchronous pulley 5623 to rotate. This, in turn, drives the second synchronous pulley 5622 and the first synchronous pulley 5621 to rotate together via a synchronous belt. This transmits the power generated during workpiece conveying to the anti-clogging component 563, eliminating the need for an additional power unit to drive the cleaning components. Power transmission between the first synchronous pulley 5621 and the rotating main shaft 5631 is achieved through a coupling. This allows the rotating main shaft 5631 to circulate within the arc-shaped filter screen 5615. Multiple sets of mounting side brackets 5632, attached to the surface of the rotating main shaft 5631, move in a circular motion, causing the outerly mounted anti-clogging cleaning brushes 5633 to continuously sweep back and forth against the filter surface of the arc-shaped filter screen 5615. The side frame 5632 uses a screw-fixed installation method to allow for the disassembly and replacement of the anti-clogging cleaning brush 5633. Once the brush is worn, it can be quickly replaced. The cleaned particles and impurities fall into the cleaning receiving frame 5617, continuously stripping the welding slag and metal dust accumulated on the surface of the filter screen, maintaining the smooth flow of flue gas, reducing the occurrence of blockages, and allowing the fume purification process to run synchronously with the workpiece conveyor 2. This reduces the number of times the equipment needs to stop for filter cleaning, ensuring that automatic and semi-automatic electric arc and plasma arc welding machines can carry out spot welding operations without interruption. It effectively improves the power linkage effect and fume filter cleaning capability of plasma arc welding equipment in the high-end intelligent manufacturing equipment industry, and can improve the work efficiency during equipment processing.

[0026] The implementation principle of the micro-arc spot welding device for surface mount component terminals in this application embodiment is as follows: During the application of this equipment, its PLC controller 55 is equipped with an intelligent welding system. During use, after the equipment is put into operation, the PLC controller 55 controls the start-up and shutdown sequence of all electrical components inside the device. The operator first places the surface mount component terminal to be processed onto the support plate 33 of the clamping module 3. The support plate 33 bears the load brought by the workpiece by the support shafts 37 connected at both ends, which can disperse the force generated by the weight of the workpiece. Then, the clamping cylinder 35 starts to operate. The output end of the clamping cylinder 35 pushes the clamping plate 36 to move towards the workpiece. The clamping plate 36 is supported by the linear anti-slip arrangement on its surface. Stripes 38 increase the friction between the contact surfaces, completing the clamping and fixing of the chip component terminals. The fixing plate 31 is assembled on the surface of the conveyor table 2 with screws. The operator can disassemble and replace the matching set of fixture modules 3 according to the specifications of the workpiece to be processed. The conveyor table 2 rotates cyclically inside the conveyor frame 1 under the power of the first motor 4. The conveyor table 2 drives each set of fixture modules 3 with the workpiece already loaded to move forward in sequence. The workpiece enters the corresponding processing area of ​​the automatic and semi-automatic electric arc plasma arc welding machine inside the box 51 through the inlet and outlet 52. This can effectively improve the workpiece adaptability and operation convenience of plasma arc welding equipment in the high-end intelligent manufacturing equipment industry.

[0027] After the workpiece arrives at the welding station, the arc welding mechanism 5 enters the workflow under the scheduling of the intelligent welding system. The lifting cylinder 531 extends and retracts to adjust the vertical height of the micro-beam plasma arc welding torch 534 inside the automatic / semi-automatic arc plasma arc welding machine. The bottom end of the lifting cylinder 531 connects to the mounting sleeve 5321. After the second motor 5322 installed inside the mounting sleeve 5321 starts running, it drives the adjusting guide rail 5323 to complete the circumferential rotation. The travel direction of the adjusting guide rail 5323 follows the direction of rotation. The rotation of the second motor 5322 is modified, allowing the slider 5325 to switch between multiple positions. The slider 5325 can then drive the entire angle adjustment assembly 533 connected to the rear end to achieve multi-directional lateral displacement. The bellows cover mounted at the bottom of the adjusting guide rail 5323 isolates metal debris splashed during spot welding, preventing debris from falling into the sliding area of ​​the lead screw 5324 and slider 5325 and causing jamming. The third motor 5326 outputs power to drive the lead screw 5324 to rotate. The lead screw 5324 relies on... The threaded drive drives the slider 5325 to slide along the inner cavity of the adjusting guide rail 5323. After the slider 5325 moves, the horizontal position of the micro-beam plasma arc welding gun 534 is finely adjusted again. The angle adjustment base 5331 receives the displacement transmitted from the slider 5325. The power output of the fourth motor 5334 is transmitted through the gearbox 5333 to drive the fine adjustment cylinder 5332 to swing, thereby changing the tilt angle of the micro-beam plasma arc welding gun 534. The fine adjustment cylinder 5332 itself can perform telescopic movement. The telescopic stroke of the fine adjustment cylinder 5332, together with the telescopic stroke of the lifting cylinder 531, forms a two-stage telescopic structure. After the vertical height, horizontal position, and tilt angle are all adjusted, the intelligent welding system controls the two-stage telescopic components to change the distance between the welding gun tip and the chip component terminal, thereby adapting to different spot welding positions on the surface of various chip component terminals. This can effectively improve the point adjustment coverage and actual welding operation effect of automatic and semi-automatic plasma arc welding equipment in the high-end intelligent manufacturing equipment industry.

[0028] When spot welding is running continuously, the purification module 56 starts its workflow synchronously with the intelligent welding system. After the negative pressure fan 5612 starts, it creates a negative pressure environment inside the purification box 5611. The welding fumes generated by the automatic and semi-automatic electric arc plasma arc welding machine performing micro-arc spot welding inside the arc welding box 51 are drawn by the negative pressure to the suction hood 5614. The arc-shaped filter screen 5615 intercepts the metal dust and welding slag particles mixed in the fumes. The fumes that have passed through the initial filtration pass through the purification core installed inside the purification box 5611 for secondary treatment. The processed fumes are then transported to the external purification system for further treatment through the external pipeline. When the conveyor 2 is running, the built-in drive shaft rotates synchronously. The drive shaft drives the third synchronous pulley 5623 to rotate. The synchronous belt receives the power from the third synchronous pulley 5623 and then drives the second synchronous pulley 5622 and the first synchronous pulley 562. 1. The first synchronous wheel 5621 drives the rotating main shaft 5631 to rotate continuously. The rotating main shaft 5631 drives all the mounting side frames 5632 to rotate cyclically. The anti-clogging cleaning brush plate 5633, which is fixed on the outside of the mounting side frame 5632, sweeps back and forth against the filter surface of the arc-shaped filter screen 5615. Every time the conveyor table 2 completes a rotation stroke for switching workpiece positions, the anti-clogging cleaning brush plate 5633 completes a round of cleaning process. The brushed-off particulate impurities fall down into the cleaning receiving frame 5617. The operator can pinch the slot to pull the cleaning receiving frame 5617 out from the side slot 5616 and pour out the accumulated waste residue. After the sealed maintenance cover plate 5613 is removed, the purification core inside the purification box 5611 can be taken out or replaced. This can continuously optimize the dust purification capacity and self-cleaning operation effect of the plasma arc welding equipment in the high-end intelligent manufacturing equipment industry.

[0029] After the spot welding process of a single set of surface mount component terminals is completed, the conveyor 2 continues to rotate. The currently processed workpiece leaves the arc welding box 51 along with the fixture module 3. The next set of fixture modules 3, carrying the workpiece to be processed, is then sent to the corresponding welding station of the automatic / semi-automatic arc plasma arc welding machine under the control of the intelligent welding system. The switching process between stations will not produce any interruptions, and the entire process can run continuously. This technical solution uses the power generated by the operation of the conveyor 2 to drive the entire transmission assembly 562 and the anti-clogging assembly 563. It does not require an additional independent drive component to drive the filter cleaning component. Each station switch of the conveyor 2 can trigger a round of cleaning operation on the surface of the arc-shaped filter 5615. The semi-automatic electric arc plasma arc welding machine performs welding and slag removal operations simultaneously. Particles accumulated on the filter surface can be immediately removed, preventing them from clogging the suction hood 5614. The purification core and purification pipes eliminate the need for frequent machine shutdowns for manual cleaning of the purification module 56. The screw-fixed mounting plate 31 allows for quick disassembly and replacement of the fixture module 3. The fixture module 3 can be replaced with the appropriate one for various shapes and sizes of surface mount components. The two-stage telescopic structure, consisting of the lifting cylinder 531 and the fine-tuning cylinder 5332, combined with the circumferential position adjustment group 532 and the angle adjustment group 533, allows for vertical height, multi-directional horizontal displacement, welding torch tilt angle, and welding torch tip extension / retraction. The micro-beam plasma arc welding torch 534, controlled by an intelligent welding system, is positioned in multiple dimensions. A bellows cover prevents metal debris from entering the transmission components inside the adjusting guide rail 5323, reducing the probability of jamming in sliding components. A dust collection frame 5617 centrally collects and cleans fallen waste, preventing it from scattering into the various cavities of the arc welding box 51 and interfering with the operation of other components. A sealed maintenance cover 5613 facilitates daily disassembly and assembly of the purification core. The interconnected structures ensure smooth workpiece transport. The entire process, including multi-dimensional torch position control, arc spot welding, fume purification, and real-time filter cleaning, reduces the daily maintenance requirements of the intelligent welding system and the automatic / semi-automatic arc plasma welding system. The processing time of the sub-arc welding machine can comprehensively improve the continuous operation efficiency and overall application level of intelligent plasma arc welding equipment in the high-end intelligent manufacturing equipment industry. During the application of this equipment, its intelligent welding system is the conventional PLC controller 55 programming control system in the existing high-end intelligent manufacturing equipment industry. It is an existing technology. Correspondingly, various moving control electronic components can be configured with corresponding sensors as needed, such as displacement sensors, angle sensors, encoders, pressure sensors, etc., to assist the intelligent welding system in controlling the existing PLC controller 55 programming control system in the high-end intelligent manufacturing equipment industry. It is an existing technology, so it will not be elaborated on here.

[0030] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
