It includes a sorting box 1, a protective cylinder 2 installed on one side of the sorting box 1, an inclined box 9 fixedly connected to the surface of the protective cylinder 2, a feeding cylinder 3 fixedly connected to the surface of the inclined box 9, a straight groove 5 opened on the upper surface of the sorting box 1, the upper surface of the sorting box 1 is set as an inclined surface 6, a plurality of discharge holes 7 opened on the upper surface of the sorting box 1, screws 13 rolling inside the straight groove 5, and an intermittent feeding screening mechanism provided on the surface of the feeding cylinder 3.

[0022] With the above structure, the protective cylinder 2 is set to protect the internally rotating drive disk 11, the straight groove 5 is set to guide the screw 13 to slide, the inclined surface 6 is set to facilitate the screw 13 to roll down under its own weight, and the intermittent feeding screening mechanism is set to perform intermittent feeding rolling operation.

[0023] Preferably, the intermittent feeding and screening mechanism includes a first motor 8 fixedly connected to the surface of the feeding cylinder 3, an inclined disk 17 rotatably connected to the output end of the first motor 8, a first moving rod 18 slidably connected to the surface of the feeding cylinder 3, a second moving rod 19 slidably connected to the inner surface of the inclined box 9, and a feeding hole 20 opened on the surface of the feeding cylinder 3.

[0024] The first motor 8 drives the inclined disc 17 to rotate. The inclined disc 17 drives the first moving rod 18 and the second moving rod 19 to move up and down reciprocally. The discharge hole 20 facilitates material discharge.

[0025] Preferably, the inner walls of the first moving rod 18 and the second moving rod 19 are fixedly connected with a first convex ball 21 and a second convex ball 22. The top end of the first convex ball 21 is in contact with the lower surface of the inclined disk 17, and the bottom end of the second convex ball 22 is in contact with the upper surface of the inclined disk 17.

[0026] By setting the first convex ball 21 and the second convex ball 22, the kinematic friction in contact with the inclined disk 17 is reduced.

[0027] Preferably, a second motor 10 is fixedly connected to the surface of the protective cylinder 2, and a drive disk 11 is fixedly connected to the output end of the second motor 10. The drive disk 11 is installed inside the protective cylinder 2, and the surface of the drive disk 11 is in contact with the inner wall of the protective cylinder 2. A discharge hole 12 is opened on the surface of the protective cylinder 2.

[0028] By setting a second motor 10, the drive disk 11 is driven to rotate, and the material is discharged through the discharge hole 12.

[0029] Preferably, the surface of the drive disk 11 is provided with a plurality of material slots 15, and color labels 16 are fixedly connected to the inner walls of the plurality of material slots 15. A color sensor 14 is fixedly connected to the inner wall of the inclined box 9, and the position of the color sensor 14 corresponds to the position of the color label 16.

[0030] By setting up a material trough 15 to place screws 13 and setting up a color label 16, when the color sensor 14 senses the color label 16, the first motor 8 is started to rotate through PLC control.

[0031] Preferably, a controller 4 is mounted on the surface of the sorting box 1, and the width of the inner wall of the multiple discharge holes 7 increases sequentially from top to bottom.

[0032] By setting multiple discharge holes 7 with the inner wall width increasing from top to bottom, the screws 13 fall into the discharge holes 7 of appropriate width under their own weight, thus achieving the sorting effect.

[0033] The working principle of this utility model is as follows: A precision metal parts sorting device for optical instruments, in use, starts the second motor 10, driving the drive disk 11 to rotate. When the color sensor 14 senses the color label 16, the first motor 8 is started via PLC control. The output of the first motor 8 drives the inclined disk 17 to rotate. The inclined disk 17 rotates and contacts the surfaces of the first convex ball 21 and the second convex ball 22, causing the first moving rod 18 and the second moving rod 19 to move up and down. When the first moving rod 18 descends, the second moving rod 19 slides upwards. When the first moving rod 18 rises, the second moving rod 19 slides down, thereby realizing the sequential conveying of screws 13 in the inclined box 9. The screws 13 located in the material trough 15 roll out of the discharge hole 12 under the action of gravity. One end of the screw 13 is stuck in the straight groove 5 and rolls down under the guidance of the straight groove 5. The width of the inner wall of the multiple discharge holes 7 increases from top to bottom, so that the screws 13 fall into the discharge holes 7 of appropriate width under their own gravity, realizing the sorting effect. With the above structure, screws 13 of different lengths can be sorted.
