[0002] Direct-insert LEDs, also known as plug-in light-emitting diodes, are energy-saving and environmentally friendly lighting materials for visible light. They are solid-state semiconductor devices that can convert electrical energy into visible light. In the field of LED lighting and display equipment manufacturing, the welding quality of plug-in light-emitting diodes directly affects the reliability and service life of the product.

[0003] When welding high-density LED arrays on existing circular motherboards, the linear motion mechanism of existing equipment is difficult to adapt to the circular arrangement characteristics, resulting in large deviations in welding position. The asynchrony between flux precipitation and tin bar delivery will cause fluctuations in welding quality. The flux spraying uniformity of traditional equipment is low, which seriously affects the welding wettability. Pin trimming, solder joint finishing and cleaning require multiple devices to complete in steps, which not only occupies production line space, but also causes cumulative errors due to multiple positioning. These problems seriously restrict the production efficiency and yield rate of LED display screens. To this end, we propose a tinning device for semiconductor component production.

[0018] 3. Through the cooperation of the cutting plate and the grinding cylinder, the effect of efficient pin trimming and integrated post-processing of solder joints can be achieved. When the first electric telescopic movement is retracted, the cutting plate is driven by the connecting rod mechanism to shear excess pins, and at the same time the friction plate grinds the incision to make it smooth. Then the grinding cylinder rotates to remove burrs from the solder joints, and the brush bar cleans the residual welding slag, realizing the integrated operation of shearing, grinding and cleaning, ensuring the reliability of component assembly and reducing the risk of short circuit. The activated carbon in the intake and exhaust pipes can effectively remove heavy metal particles in welding fumes. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] In this embodiment, the welding mechanism 4 includes a connecting plate 41 fixedly connected to the output arm of the robot arm 3, two groups of symmetrical first fixed rods 42 are fixedly connected to one side of the connecting plate 41, the other ends of the two groups of first fixed rods 42 are commonly fixedly connected to an arc-shaped rack 43, the other side of the arc-shaped rack 43 is fixedly connected to an arc-shaped clamping strip 44, the outer side of the arc-shaped rack 43 is meshed with a first gear 45, one end of the first gear 45 is rotatably connected to a first mounting plate 46 through a rotating shaft, the other end of the first mounting plate 46 is installed with a first motor 47, the output shaft of the first motor 47 is fixedly connected to the first gear 45, and one side of the first mounting plate 46 is fixedly connected to the second mounting plate 410.

[0031] Specifically, the connecting plate 41 serves as a transition connection between the robot arm 3 and the welding mechanism 4, transmitting the positioning power of the robot arm 3. The first fixed rod 42 is symmetrically distributed, supporting and fixing the arc rack 43 to ensure the rigidity of the transmission structure. The arc rack 43 is meshed with the first gear 45 to convert the rotational motion into precise arc motion along the arc clip 44. The arc clip 44 provides a guide track to limit the motion trajectory of the first mounting plate 46. The first gear 45 converts the rotational power of the first motor 47 into linear displacement, driving part of the structure of the welding mechanism 4 to move along the arc path. The first motor 47 provides precise rotational power to control the arc motion accuracy of the welding head 416.

[0032] In this embodiment, two sets of symmetrical limit plates 48 are rotatably connected to one side of the first mounting plate 46 , and sliding grooves 49 are provided on both inner and outer sides of the arc-shaped clamping strip 44 . The two sets of limit plates 48 are slidably connected to the inner sides of the two sets of sliding grooves 49 .

[0033] Specifically, the limit plate 48 disperses the motion load through sliding contact, thereby reducing the friction resistance when the first mounting plate 46 moves; the slide groove 49 constrains the moving direction of the limit plate 48 on both sides to ensure the movement stability.

[0034] In this embodiment, a first electric telescopic rod 412 is installed on the inner side of the second mounting plate 410, and a first connecting block 413 is fixedly connected to the outer side of the output shaft of the first electric telescopic rod 412, and a friction plate 414 is fixedly connected to one side of the first connecting block 413, and the friction plate 414 is of arc design, and a second connecting block 415 is fixedly connected to the other side of the friction plate 414, and a welding head 416 is installed at the lower end of the second connecting block 415, and a three-hole sleeve 417 is fixedly connected to the outer side of the welding head 416, and a tin bar 418 is arranged in the through hole of the three-hole sleeve 417 close to one side, and an atomizing spray head 411 is arranged in the through hole of the three-hole sleeve 417 close to the other side.

[0035] Specifically, the first electric telescopic rod 412 provides a vertical linear driving force to control the downward pressure and retraction of the welding head 416. The arc-shaped design of the friction plate 414 fits the edge of the main board 8, offsets the welding vibration through friction, and improves the welding stability.

The front ends of the two groups of second gears 420 are fixedly connected to a discharge shaft 421, and the front ends of the discharge shaft 421 are rotatably connected to one of the two groups of fixed plates 419 through a rotating shaft. The second motor 422 is fixedly connected to one of the two groups of discharge shafts 421, and the outer side of the discharge shaft 421 is provided with friction patterns.

[0037] Specifically, the second gear 420 realizes the synchronous counter-rotation of the two sets of feed shafts 421 through meshing transmission. The friction pattern on the outer side of the feed shaft 421 clamps the tin bar 418 to accurately control the feeding speed. The second motor 422 provides power for conveying the tin bar 418 to ensure synchronization of the tin material and the welding action.

[0038] In this embodiment, a storage tank 423 is installed at the upper end of the second mounting plate 410, and flux is stored inside the storage tank 423. A rack gear 424 is fixedly connected to the inner side of the storage tank 423, and a third gear 425 is meshingly connected to the outer side of the rack gear 424. The front and rear ends of the third gear 425 are rotatably connected to a support frame 426 via a rotating shaft, and the front and rear ends of the third gear 425 are fixedly connected to blades 427 via a rotating shaft. A feed pipe 428 is fixedly connected to the lower end of the support frame 426, and a feed hole is provided on the outer side of the feed pipe 428. The outer side of the feed pipe 428 is slidably connected to the storage tank 423, and the lower end of the feed pipe 428 is fixedly connected to the atomizing spray head 411.

[0039] Specifically, the rack 424 meshes with the third gear 425 to convert the linear motion of the feed pipe 428 into gear rotation. The blade 427 stirs the flux to prevent precipitation and maintain viscosity consistency. The sliding connection design of the feed pipe 428 adapts to the lifting and lowering of the atomizing spray head 411 and quantitatively delivers the flux through the feed hole.

[0040] In this embodiment, the trimming mechanism 5 includes a first connecting rod 51 fixedly connected to the first connecting block 413, the lower end of the first connecting rod 51 is rotatably connected to two groups of cross-symmetrical first connecting rods 52 through a sleeve, the lower end of the first connecting rod 52 is rotatably connected to the second connecting rod 53 through a rotating shaft, the inner sides of the two groups of second connecting rods 53 are rotatably connected to a fixed rotating shaft 54, one end of the fixed rotating shaft 54 ​​is fixedly connected to a second fixed rod 55, the upper end of the second fixed rod 55 is fixedly connected to the second mounting plate 410, and the lower ends of the two groups of second connecting rods 53 are fixedly connected to a cutting plate 56.

[0041] Specifically, the first connecting rod 52 and the second connecting rod 53 convert the linear motion of the first electric telescopic rod 412 into a shearing motion of the cutting plate 56 .

[0042] In this embodiment, a friction plate 57 is fixedly connected to one side of one of the two groups of cutting plates 56 close to the main board 8 .

[0043] Specifically, the friction plate 57 is made of hard alloy, and the cut is polished twice.

[0044] In this embodiment, the grinding mechanism 6 includes a second electric telescopic rod 61 fixedly connected to the first mounting plate 46, the output shaft of the second electric telescopic rod 61 is fixedly connected to the third mounting plate 62, a third motor 63 is installed on one side of the third mounting plate 62, and the other side of the third mounting plate 62 is rotatably connected to the third electric telescopic rod 64, the output shaft of the third motor 63 is fixedly connected to the third electric telescopic rod 64, the output shaft of the third electric telescopic rod 64 is fixedly connected to the detection plate 65, one end of the detection plate 65 is fixedly connected to two groups of symmetrical second connecting rods 66, the same end of the two groups of second connecting rods 66 is commonly fixedly connected to a grinding cylinder 68, and brush strips 67 are provided on the outer sides of the two groups of second connecting rods 66.

[0045] Specifically, the output shaft of the second electric telescopic rod 61 pushes the third mounting plate 62 to move, so that the detection plate 65 is aligned with the plug-in light-emitting diode 9, and the output shaft of the third motor 63 drives the third electric telescopic rod 64 to rotate. The output shaft of the third electric telescopic rod 64 drives the detection plate 65 to approach the plug-in light-emitting diode 9, and the detection plate 65 drives the second connecting rod 66 to rotate. When the second connecting rod 66 is in contact with the plug-in light-emitting diode 9, the outer side of the plug-in light-emitting diode 9 is cleaned by the brush strip 67 to avoid residual welding slag. The second connecting rod 66 drives the grinding cylinder 68 to fit the tin point position and rotate under the kinetic energy of the third motor 63, so as to remove excess solder and reduce the risk of solder joint burrs or short circuits.

[0046] In this embodiment, the outer side of the second electric telescopic rod 61 is fixedly connected to an air pump 69 through a sleeve, the inner side of the air pump 69 is provided with activated carbon, the input port of the air pump 69 is fixedly connected to an air intake pipe 611, the output port of the air pump 69 is fixedly connected to an exhaust pipe 610, and the inner walls of the exhaust pipe 610 and the air intake pipe 611 are both provided with activated carbon.

[0047] Specifically, the air pump 69 absorbs harmful gases and particles generated by welding and grinding through the air inlet pipe 611, and after being filtered by activated carbon, outputs clean air flow from the exhaust pipe 610 to blow the surface of the mainboard 8 to accelerate the cooling of the solder joints.

[0048] Working principle: when in use, the main board 8 is clamped on the upper end of the mounting frame 7, and the plug-in light emitting diode 9 is inserted into the assembly groove of the main board 8, the mechanical arm 3 on one side of the bracket 2 is started, and the mechanical arm 3 is adjusted to the welding position through the connecting plate 41 and the first fixing rod 42, and the first motor 47 is started, and its output shaft drives the first gear 45 to rotate, and the first gear 45 is meshed with the arc-shaped rack 43, so that the first mounting plate 46 moves along the arc-shaped clamping strip 44, and the limit plate 48 slides in the slide groove 49, reducing the friction resistance of the first mounting plate 46 when it moves, ensuring that the second mounting plate 410 is accurately close to the welding point;

[0049] The first electric telescopic rod 412 is started, and its output shaft pushes the first connecting block 413 to move, which in turn drives the friction plate 414, the second connecting block 415 and the welding head 416 to move down to the welding position. The friction plate 414 is close to the edge of the main board 8 to ensure the stability of the welding head 416. When the welding head 416 moves down, the atomizing spray head 411 moves down through the three-hole sleeve 417, and the atomizing spray head 411 pulls the feeding pipe 428. The feeding pipe 428 drives the third gear 425 through the support frame 426. The third gear 425 rotates along the rack 424, driving the blades 427 to stir the soldering flux in the storage tank 423 to improve the uniformity of atomization. The atomizing spray head 411 sprays the soldering flux on the welding position of the plug-in light-emitting diode 9, and starts the second motor 422 on one side of the fixing plate 419 to drive a set of feed shafts 421 to rotate. Through the meshing of the two sets of second gears 420, the two sets of feed shafts 421 rotate in opposite directions, clamping and conveying the tin bar 418, ensuring that the tin bar 418 is always aligned with the welding head 416;

[0050] After the welding head 416 completes the spot soldering, the first electric telescopic rod 412 retracts, driving the first connecting block 413 to move upward, and sequentially links the first connecting rod 51, the first connecting rod 52 and the second connecting rod 53 to rotate around the fixed shaft 54, driving the cutting plate 56 to cut the redundant pins of the plug-in light-emitting diode 9. When the first mounting plate 46 moves, it drives the welding head 416 to move, thereby cleaning the burrs on the edge of the main board 8. When the cutting plate 56 moves, it rubs the incision of the pin through the friction plate 57 to make the incision smoother to avoid affecting the assembly. The second fixed rod 55 is connected to the second mounting plate 410 to keep the fixed shaft 54 ​​stable.

[0051] The second electric telescopic rod 61 is started, and its output shaft pushes the third mounting plate 62 to move, so that the detection plate 65 is aligned with the plug-in light emitting diode 9. The third motor 63 is started, and the output shaft of the third motor 63 drives the third electric telescopic rod 64 to rotate. The third electric telescopic rod 64 is started, and the output shaft of the third electric telescopic rod 64 drives the detection plate 65 to approach the plug-in light emitting diode 9. The detection plate 65 drives the second connecting rod 66 to rotate. When the second connecting rod 66 is fitted with the plug-in light emitting diode 9, the outer side of the plug-in light emitting diode 9 is cleaned by the brush strip 67 to avoid residual welding slag. The second connecting rod 66 drives the grinding cylinder 68 to fit the tin point position and rotate under the kinetic energy of the third motor 63, so as to remove excess solder and reduce the risk of solder joint burrs or short circuits.

[0052] The air pump 69 is started, and the air inlet pipe 611 absorbs harmful gases and particles generated by welding and grinding. After being filtered by activated carbon, a clean air flow is output through the exhaust pipe 610 to blow the surface of the mainboard 8 to accelerate the cooling of the solder joints.
