[0044] Working principle: the conveyor belt 1 can be connected to an external clamp, the LED lamp driver board is placed on the conveyor belt 1 or on the top of the clamp connected to the conveyor belt 1, the welding rod is placed on the feed plate, the LED filament is manually clamped and fixed by the electric clamp 402, in the initial state, the first gear 413 and the third gear 431 are not in contact, the slide bar 445 is at the top of the vertical part of the "L"-shaped through groove 450, the cleaning plate 447 is inside the cleaning bin 45, the conveyor belt 1 is turned on, and when the conveyor belt 1 transports the LED lamp driver board to the processing device 4, the rotary drive component 411 is turned on to drive the rotating shaft 412 to rotate, the rotating shaft 412 rotates to drive the first gear 413 and the first movable wheel 414 to rotate, and the first movable wheel 414 rotates to drive the screw 415 to rotate. The screw rod 415 rotates, and the adjusting member 416 inside the adjusting chamber 410 moves downward. The adjusting member 416 moves downward, and the heating component 417 and the welding head 418 move downward until the welding head 418 moves downward to the welding point of the LED lamp driving board through the through slot 450. In this process, the second linear drive component 43 is turned on, and the second linear drive component 43 is turned on to drive the second output rod 430 and the third gear 431 to move downward until the third gear 431 is meshed and connected with the first gear 413. At this time, the sliding rod 445 moves downward to the bottom of the vertical part of the "L"-shaped through slot 450, and the cleaning plate 447 moves downward to the outside of the bottom of the cleaning chamber 45. The first gear 413 rotates to drive the second gear 4190 to rotate, and the second gear 4190 rotates through the second output rod 4 30. The second linear drive assembly 43 rotates, the second output rod 430 rotates to drive the through rod 44 to rotate, the through rod 44 rotates to drive the fixed rod 440 to rotate through the rotating disk 441, the fixed rod 440 rotates to drive the rotating arm 442 to make a circular motion with the fixed rod 440 as the center, the movement of the rotating arm 442 drives the rotating rod 443 to rotate, the rotating rod 443 rotates to drive the movable plate 444, the connecting plate 446, and the cleaning plate 447 to make a circular motion. Since the front end of the movable plate 444 is restricted by the horizontal part of the "L"-shaped through groove 450 and the sliding rod 445, the rotation of the rotating rod 443 will drive the movable plate 444, the connecting plate 446, and the cleaning plate 447 to make a linear reciprocating motion along the cleaning bin 45. At this time, the conveyor belt 1 is conveyed When the LED lamp driving board is cleaned, the cleaning plate 447 moves linearly back and forth to clean the welding points of the LED lamp driving board to prevent dust or other debris from sticking to it, which may cause the LED lamp driving board and the LED filament to be loosely welded and have many welds during subsequent welding, thereby reducing the welding quality of the LED lamp driving board and the LED filament. When the LED lamp driving board is transported to the welding head 418 and the welding head 418 moves down to the welding point, the cleaning plate 447 moves to the leftmost side of the horizontal part of the "L"-shaped through groove 450, and then the second linear drive component 43 is turned on to retract the second output rod 430 and move it upward so that the third gear 431 is no longer engaged with the first gear 413. At this time, the upward movement of the second output rod 430 can reset the cleaning plate 447 to the inside of the cleaning bin 45.When the cleaning plate 447 is reset to the inside of the cleaning chamber 45, it no longer contacts the LED lamp driver board. Then the first linear drive component 400 is turned on to drive the first output rod 401, the electric clamp 402 and the LED filament to move downward until the two joints of the LED filament are in contact with the welding points of the LED lamp driver board. At this time, the conveying head 30 on the top of the feeding device 3 moves the conveying plate 31 and the welding rod to the welding head 418. The welding head 418 can normally melt the welding rod through the heating component 417 and drip it on the welding point of the LED lamp driver board and the surface of the LED filament. Therefore, the device can clean the impurities on the welding point of the LED lamp driver board before welding, so as to avoid dust or other debris sticking to it, resulting in the situation that the LED lamp driver board and the LED filament are not firmly welded and there are many welds during subsequent welding, thereby improving the welding quality of the device and facilitating user use.

[0045] During the downward movement of the welding head 418, the first movable wheel 414 rotates through the movable belt 42 to drive the second movable wheel 419 to rotate, and the second movable wheel 419 rotates through the shaft 4191 to drive the second gear 4190 to rotate, and the second gear 4190 rotates to drive the tooth plate 461 to make a linear motion away from the air storage bin 46, and the movement of the tooth plate 461 drives the piston plate 460 to move inside the air storage bin 46. At this time, the air pressure change inside the air storage bin 46 draws the external gas into the air storage bin 46 through the blowing plate 470 and the air pipe 463, and the air storage bin 46 is turned off when the welding head 418 completes the downward movement. The gas filling is completed in the gas storage bin 46. After the welding head 418 completes welding, the rotating drive component 411 is reversed to drive the rotating shaft 412 to reverse so that each component is reset. The first movable wheel 414 is reversed through the rotating shaft 412. The first movable wheel 414 is reversed to drive the second movable wheel 419, the shaft 4191 and the second gear 4190 to reverse through the movable belt 42. The second gear 4190 is reversed to drive the tooth plate 461 to make a linear motion toward the gas pipe 463. The movement of the tooth plate 461 drives the piston plate 460 to make a linear motion toward the gas pipe 463 in the gas storage bin 46. The movement of the piston plate 460 increases the air pressure inside the air storage chamber 46, and the air inside the air storage chamber 46 is transported to the blowing plate 470 through the valve port 464 and the air delivery pipe 463, and then blown out by the blowing plate 470 to the welding point of the LED lamp driving board to assist the welding rod at the welding point of the LED lamp to quickly cool and solidify. In addition, since the forward movement distance of the piston plate 460 is in a certain proportion to the upward movement distance of the welding head 418, that is, the gas flow rate blown out by the blowing plate 470 is related to the upward movement speed of the welding head 418, and the upward movement speed of the welding head 418 is related to the rotation shaft 412 driven by the rotating drive assembly 411. The rotation speed is related, and the rotating drive component 411 maintains a uniform speed operation, that is, in the present application, the wind speed of the blowing plate 470 is kept constant to avoid the unsolidified welding rod being blown by the faster wind speed to other positions of the LED lamp driver board due to the faster blowing speed at the blowing plate, resulting in reduced welding firmness between the LED lamp driver board and the LED filament. The blowing of the blowing plate 470 assists the welding rod in cooling the welding rod to avoid the LED filament being skewed at the welding point of the LED lamp driver board due to the welding rod being transported away when the LED lamp driver board is not cooled, thereby improving the welding quality and welding efficiency of the device and facilitating user use.
