[0022] As shown in Figure 3 Auxiliary assembly includes stop block 8, first screw 9, second motor 16, gear 17 and rack 18, the rightmost side of support frame 2 is threadedly connected with first screw 9, the top of first screw 9 is rotatably connected with stop block 8, stop block 8 is close to the right end of second track 4, and then blocks the channel mouth, the rear side of connecting frame 14 is installed with second motor 16, gear 17 is connected on the output shaft of second motor 16, rack 18 is welded on the rear side wall of second track 4, and gear 17 is engaged with rack 18.

[0023] AsFigures 1-2 As shown in the drawings, the first motor 5, the rollers 6 and the conveying belt 7 are further included. The rollers 6 are rotatably connected to the left side of the top of the support frame 2, and the conveying belt 7 is wound around the rollers 6 for conveying elements. The conveying belt 7 is located below the first track 3 and communicates with the passage of the first track 3. The first motor 5 is bolted to the right side of the front of the first track 3, and the output shaft of the first motor 5 is connected to the rollers 6.

[0024] As shown in the drawings, Figure 1 and Figure 4 The rotating frame 19 and the transparent plate 20 are further included. The rotating frame 19 is rotatably connected to the front side of the second track 4, and the transparent plate 20 for limiting elements is connected to the rotating frame 19. The transparent plate 20 covers the top surface of the second track 4. The transparent part of the transparent plate 20 is made of reinforced glass, which has high wear resistance and can avoid damage caused by friction with the original element.

[0025] When conveying electronic components, the channel of the second track 4 is cleaned first. When operating, the first screw rod 9 is rotated first to drive the stop block 8 to move downwards so that it no longer blocks the right end of the second track 4. Then the transparent plate 20 is rotated to open to drive the rotating frame 19 to rotate. Subsequently, the second motor 16 is started, the output shaft of the second motor 16 drives the gear 17 to rotate, the gear 17 drives the second motor 16, the connecting frame 14 and the cleaning brush 15 to move to the right side through the meshing of the gear 17 and the rack 18, and then drives the connecting block 13, the sliding frame 11 and the second screw rod 12 to move to the right side with the limiting frame 10. The second track 4 is cleaned by the cleaning brush 15. When moving to the rightmost side, the impurities and dust swept out are pushed out through the right end of the second track 4. The second motor 16 is reversely operated to drive the gear 17 to reverse along the rack 18 to move to the left side to reset, and then drive the cleaning brush 15 and other components to move to reset. After resetting, the second motor 16 is automatically turned off. Then the second screw rod 12 is rotated to move upwards to drive the connecting block 13 to move upwards, and then drive the connecting frame 14 and the cleaning brush 15 to move upwards to separate from the second track 4, so as to facilitate the feeding operation. Similarly, when cleaning is needed, the second screw rod 12 is reversed to drive the cleaning brush 15 to move downwards to reset in the second track 4. Then the transparent plate 20 is reversed to close, and the first screw rod 9 is reversed to drive the stop block 8 to move upwards to reset. After the cleaning work is completed, the electronic components are placed in the vibration disc 1. After the vibration disc 1 is started, vibration is generated to orderly arrange the small components in bulk, so as to be conveyed one by one to the first track 3, and then contact the conveying belt 7. The first motor 5 is started, the output shaft drives the roller 6 and the conveying belt 7 to rotate, which can quickly convey the components to the second track 4, and then slide along the second track 4. When moving to the inductor 41, the inductor 41 senses the components to light. At this time, the mechanical hand clamps the components to the machining area. The transparent plate 20 blocks the top surface of the second track 4. When the components enter the second track 4, the components can be prevented from being raised upwards due to the pushing force, so as to ensure the stability of the component conveying. After the work is completed, the related equipment can be turned off.
