A guide rod 14 penetrating the translation groove 7 and the arc groove 13 is installed at the bottom of the slide seat 8. A plurality of arc convex blocks 18 are arranged at equal angles on the outer side of the bottom of the turntable 6. The translation groove 7, the arc groove 13 and the arc convex block 18 correspond to each other. An inner tooth 15 is arranged on the inner side of the swivel 12. A first motor 16 is mounted on the turntable 6. A rotating tooth 17 is mounted on the output end of the first motor 16, and the rotating tooth 17 is meshed with the inner tooth 15. A cam divider 19 is mounted on the bottom side of the base 1, and the output end of the cam divider 19 is connected to one of the rotating shafts 5, and the input end of the cam divider 19 is connected to the output end of the second motor 20. Both are equipped with synchronous wheels 38, and the two synchronous wheels 38 are connected by synchronous belts 39. The slide 8 of the diode loading and unloading mechanism 2 and the diode discharge seat 9 are fixedly connected by the first bolt 10. The top side of the slide 8 of the resistor loading and unloading mechanism 3 is equipped with guide pillars 21 all around, and the guide pillars 21 penetrate the resistor discharge seat 11. A through hole is provided at the center of the resistor discharge seat 11, and the second bolt 23 penetrates the through hole and is connected to the slide 8. The outside of the guide pillar 21 and below the resistor discharge seat 11 are provided with a first spring 22. The second motor 20 is used to realize the rotation of the turntable 6 through the diode loading and unloading mechanism 2 and the resistor loading and unloading mechanism 3, and then during the rotation process, the diode on the diode discharge seat 9 and the diode on the resistor discharge seat 11 are connected. The resistors are automatically matched, which greatly improves the welding efficiency of diodes and resistors. The slide 8 and the diode discharge seat 9 are connected by the first bolt 10, and the slide 8 and the resistor discharge seat 11 are connected by the second bolt 23, which is convenient for disassembly, assembly and replacement of the diode discharge seat 9 and the resistor discharge seat 11. The rotation of the swivel 12 is realized by the first motor 16. The rotating swivel 12 acts on the guide rod 14 through the arc groove 13, driving the guide rod 14 and the slide 8 to move, so as to realize the movement and adjustment of all slides 8 on the turntable 6, and then adjust the position of the diode discharge seat 9 and the resistor discharge seat 11, and adjust the spacing between the two diode discharge seats 9 and the resistor discharge seat 11 when welding, so as to meet the welding requirements of diodes and resistors of different specifications.

[0021] The resistor loading and unloading mechanism 3 includes side columns 24 symmetrically arranged on both sides of the base 1. A lifting frame 25 is slidably installed between the two side columns 24. A welding head 26 is installed on the lifting frame 25. A second slide rail is provided inside the side column 24. A slider slidably installed with the second slide rail is installed on the welding auxiliary mechanism 4. A connecting seat 34 is installed on the bottom side of the lifting frame 25. Guide wheels 35 that roll along the bottom side of the rotating ring 12 and the arc-shaped protrusion 18 are installed at both ends of the connecting seat 34. Slide columns 36 penetrating the connecting seat 34 are symmetrically installed on the base 1. A stop block is installed at the top end of the connecting seat 34. A second spring 37 is sleeved outside the slide column 36 and below the connecting seat 34. As the turntable 6 rotates, at this time, the guide wheels 35 roll along the arc-shaped protrusion 18. Through the elastic deformation of the second spring 37, the lifting frame 25 is driven to reciprocally lift on the side column 24, thereby realizing the lifting movement of the welding head 26. Moreover, the lifting movement of the welding head 26 is matched with the rotation of the diode feeding seat 9 and the resistor feeding seat 11, so as to realize automatic welding when the diode and the resistor are matched, with a high degree of automation.

[0022] A limiting component for limiting the welded diode and a pressing component for separating the resistor feeding seat 11 from the resistor when it moves downward are installed on the side column 24. The limiting component includes a first mounting plate 27 installed on the side column 24. A first air cylinder 28 is installed on the first mounting plate 27. A ring-shaped wheel set 29 is installed at the telescopic end of the first air cylinder 28. A number of rotating rollers 30 are installed inside the ring-shaped wheel set 29. The pressing component includes a second mounting plate 31 installed on the side column 24. A second air cylinder 32 is installed on the second mounting plate 31. A ball 33 is installed at the telescopic end of the second air cylinder 32. After welding is completed, the resistor and the resistor feeding seat 11 are separated through the pressing component, facilitating the synchronous movement of the resistor with the diode. The welded diode is limited and guided through the limiting component to prevent the diode from falling off the diode feeding seat 9.

[0023] Working principle: The diode is placed on the diode feeding seat 9 by the manipulator, and the resistor is placed on the resistor feeding seat 11. At this time, the second motor 20 works, and the cam divider 19 drives the rotation of the rotating shaft 5. The synchronous pulley 38 and the synchronous belt 39 drive the two rotating shafts 5 and the two turntables 6 to rotate together. When the diode and the resistor rotate past the welding head 26, at this time, the pins of the diode and the resistor are matched, and the welding is completed by the descending welding head 26. After the welding is completed, the telescopic end of the second air cylinder 32 moves downward until the ball 33 contacts the resistor feeding seat 11, driving the resistor feeding seat 11 to move downward along the guide post 21, compressing the first spring 22. At this time, the resistor is separated from the resistor feeding seat 11. At this time, the turntable 6 continues to rotate, and the ball 33 rolls along the top side of the resistor feeding seat 11. When the ball 33 is separated from the resistor feeding seat 11, the compressed first spring 22 returns to its original state, driving the resistor feeding seat 11 to move upward. The diode on the diode feeding seat 9 moves at the bottom of the annular wheel group 29, and the diode is limited and guided by the roller 30. When the turntable 6 rotates until the welded diode breaks away from the bottom of the annular wheel group 29, at this time, the welded diode and resistor are taken off by the manipulator; The rotation of the turntable 6 drives the rotation of the arc-shaped convex block 18. At this time, the guide wheel 35 rolls along the arc-shaped convex block 18. When the guide wheel 35 rolls from the high point to the low point of the arc-shaped convex block 18, at this time, the connecting seat 34 moves downward along the guide wheel 35, compressing the second spring 37, realizing the downward movement of the lifting frame 25 and the welding head 26. When the guide wheel 35 rolls from the low point to the high point of the arc-shaped convex block 18, at this time, the compressed second spring 37 returns to its original state, realizing the upward movement of the lifting frame 25 and the welding head 26. The center of the bottom side of the arc-shaped convex block 18 corresponds to the centers of the diode feeding seat 9 and the resistor feeding seat 11, that is, when the welding head 26 descends to the lowest point, the diode and the resistor are in the matching stage; The sliding seat 8 and the diode feeding seat 9 are connected by the first bolt 10, and the sliding seat 8 and the resistor feeding seat 11 are connected by the second bolt 23, which is convenient for disassembling and replacing the diode feeding seat 9 and the resistor feeding seat 11. The first motor 16 works to drive the rotating gear 17 to rotate, and the rotating ring 12 is rotated in cooperation with the meshing internal gear 15. The rotating rotating ring 12 acts on the guide rod 14 through the arc-shaped groove 13, driving the guide rod 14 to move along the translation groove 7. At this time, the sliding seat 8 connected to the guide rod 14 moves on the first guide rail, realizing the simultaneous movement adjustment of the sliding seat 8 on the turntable 6, adjusting the distance between the two diode feeding seats 9 and the resistor feeding seat 11 during welding, and meeting the welding requirements of different specifications of diodes and resistors.
