[0056] As shown in the figure, the application provides a small hollow cylinder sorting device, which comprises a vibrating disc 1 and a buffer mechanism 2, the component discharge port of the vibrating disc 1 is connected with the receiving port of the buffer mechanism 2, wherein the vibrating disc 1 comprises a tray 11, a spiral track 12, a transfer bin 13, a sorting track 14 and an output track 16, the spiral track 12 is coiled in the tray 11 and is inclined upward along the inner wall of the tray 11, and the spiral track 12 realizes the orderly output of the material through the vibration of the vibrator, so that the hollow cylinder parts 100 at the bottom of the vibrating disc 1 are gradually conveyed to the transfer bin 13 at a high position, the transfer bin 13 is a bin body structure protruding outward from the side of the tray 11, the bottom of the transfer bin 13 is provided with an arc-shaped guide groove 131, the hollow cylinder parts 100 will gradually move into the guide groove 131, based on the low position of the guide groove 131 in the transfer bin 13, the hollow cylinder parts 100 gradually and automatically move to the guide groove 131 of the transfer bin 13, and the length direction of the hollow cylinder parts 100 will gradually and automatically be placed and sorted along the length direction of the groove body, the sorting track 14 is an arc-shaped guide rail, the sorting track 14 is gradually and inclined downward along the conveying direction, the end of the sorting track 14 is close to the input side of the sorting gear 15 and is located at the upper edge of the input side of the sorting gear 15, so that the components are more easily picked up by the sorting gear 15, the sorting track 14 is provided with a track groove for conveying components, the track groove is used for conveying the components in a specific placement direction, for example, the placement direction of the components is basically along the conveying direction of the track groove, therefore, the head end of the sorting track 14 is connected with the groove body structure of the transfer bin 13, the end of the sorting track 14 is connected with the sorting gear 15, the hollow cylinder parts 100 in the sorting track 14 are combined with the guiding effect of the sorting track 14 and the auxiliary effect of vibration, so that the hollow cylinder parts 100 are more easily picked up by the sorting gear 15 when the sorting gear 15 rotates, the side wall of the tray 11 is provided with a sorting motor 17, the output shaft of the sorting motor 17 is connected with the shaft center of the sorting gear 15, and the sorting motor 17 is used for driving the sorting gear 15 to rotate.When the sorting gear 15 rotates to a specific position on the input side, the length direction of the sorting teeth 152 on the outer edge of the sorting gear 15 can be opposite to the conveying direction of the end of the sorting track 14, so that the parts on the sorting track 14 that meet the placement direction (the large hole end 101 faces forward) can be smoothly screened out, and the parts that do not meet the placement direction will fall from the sorting track 14 back to the bottom of the vibration disc 1. Specifically, the sorting teeth 152 of the sorting gear 15 are arranged in width so that they can be smoothly inserted into the large hole end 101 of the hollow cylindrical part 100, but cannot be inserted into the small hole end 102. The sorting gear 15 rotates the sorted hollow cylindrical part 100 from one side to the other side, and the conveying direction of the hollow cylindrical part 100 is reversed. Then, the hollow cylindrical part 100 falls into the output track 16 through the sorting teeth 152 of the sorting gear 15. The input end of the output track 16 is located near the output side of the sorting gear 15 and is located below the edge of the output side of the sorting gear 15. At this time, the hollow cylindrical part 100 is reversed so that the small hole end 102 faces the same direction as the moving direction of the hollow cylindrical part 100 on the output track 16 (the small hole end 102 faces forward). The hollow cylindrical part 100 enters the guide pipe 21 through the output track 16, is sorted in sequence, and is temporarily stored.

The output track 16 is gradually inclined downward along the conveying direction. The hollow cylindrical part 100 will slide into the guide pipe 21 under the double action of its weight and vibration. The protective limiting teeth 153 and the sorting teeth 152 form a clamping gap 154 for the passage of the hollow cylindrical part 100.

The second detection station 52 is used to detect whether the hole in the large hole end 101 of the hollow cylindrical part 100 is deformed or has foreign matter. When the detection mechanism 5 detects the part with the size difference between the two end holes, the detection mechanism 5 combines the size difference between the two end holes of the part and designs different diameter sizes of the two detection station probes. The first detection station 51 is adapted to the size of the small hole end 102, and the second detection station 52 is adapted to the size of the large hole end 101. When the small hole end 102 is detected first, if the probe I 5411 head end of the first detection station 51 can enter the hole in the small hole end 102, it indicates that the hole in the small hole end 102 is not deformed or has no foreign matter. Otherwise, the probe I 5411 cannot enter the hole in the small hole end 102, and the probe I 5411 compresses the spring 542, so that the probe I 5411 is lowered to the quality detection optical fiber 55, and it is judged that the hole in this end is deformed or has foreign matter. After the detection of the small hole end 102 is completed, the rotating cylinder drives the handling clamping jaw 41 to rotate 180 degrees. The hollow cylindrical part 100 is transferred to above the second detection station 52 by the horizontal moving assembly 44. When the large hole end 101 is detected, if the probe II 5412 head end of the large hole end 101 can enter the hole in the large hole end 101, it indicates that the hole in the large hole end 101 is not deformed or has no foreign matter. Otherwise, the probe II 5412 compresses the spring 542, and the tail end of the probe II 5412 is lowered to the quality detection optical fiber 55, and it is judged that the hole in this end is deformed or has foreign matter.

[0067] When the hole end of the hollow cylindrical part 100 is not deformed and has no foreign matter, the vertical moving assembly 43 drives the hollow cylindrical part 100 to be pressed down, the probe 541 corresponds to the end hole of the hollow cylindrical part 100, the probe 541 can smoothly enter the detection hole of the product part, the probe 541 will not be pressed down and moved to the quality detection optical fiber 55, and it is judged that the product part is qualified. When the hollow cylindrical part 100 is deformed or has foreign matter blocking, the vertical moving assembly 43 drives the hollow cylindrical part 100 to be pressed down, the probe 541 corresponds to the end hole of the hollow cylindrical part 100, and the hollow cylindrical part 100 moves downward with the vertical moving assembly 43. If the probe 541 cannot enter the end hole of the product part, the probe 541 will be pressed down and moved to the detection cavity 532, and the spring 542 is also compressed. The quality detection optical fiber 55 detects the signal of the probe 541, and it is judged that the end of the part is unqualified. After detection, the hollow cylindrical part 100 moves upward with the vertical moving assembly 43 and rises. The spring 542 is also reset, and the probe 541 is reset to the original position for the next detection.

The two split boxes are driven to open and close by the buffer motor 67. The receiving box 61 is closed to realize the buffering and discharging of the hollow cylindrical part 100. The presence or absence of the detection optical fiber 68 is used to judge whether there is material in the receiving box 61. The detection optical fiber 68 is located on the inlet side of the receiving box 61. The receiving box 61 is opened to realize the unloading.
