Through the above process, the sorting of the guide needle 6 is completed, the guide needle 6 is sorted without damage through the effective combination of the guide needle sorting mechanism 1 and the exclusion mechanism 3, the rotating body 102 and the needle positioning groove 10511 are set to realize the single needle distribution and movement of each station, effectively avoiding the phenomenon of missing needle or multiple needles, the needle positioning groove 10511 and the adsorption body 10512 are set to avoid the contact and damage of the components to the guide needle 6, and the damage-free sorting is realized. The recess 3011 in the exclusion mechanism 3 is combined with the through hole to remove the risk of bent needle, multiple needle and inclined needle, and the precision of screening bad products is improved.

[0033] As shown in Figure 3 , Figure 6 , Figure 7 , the power mechanism 2 includes a power driver 201, a power connecting rod 202, a power guide wheel 203, and a power rod fixing frame 204; wherein the output end of the power driver 201 is connected with the power connecting rod 202; the power connecting rod 202 is slidingly installed on the power rod fixing frame 204; the power connecting rod 202 is provided with the power guide wheel 203 at the end away from the power driver 201.

[0034] Specifically, in this embodiment, the power driver 201 adopts a power cylinder, and in other embodiments, the power driver 201 can also adopt a motor or other power structure that can drive the power connecting rod 202 to perform up-down telescopic movement. The output end of the power driver 201 is connected with the power connecting rod 202, and the power connecting rod 202 is provided with the power guide wheel 203 at one point, and the power connecting rod 202 drives the power guide wheel 203 to move when the power driver 201 outputs power. More specifically, the power connecting rod 202 drives the power guide wheel 203 to slide in the power guide wheel vertical groove 1021 or the power guide wheel inclined groove 1022 in the rotating body 102, which plays a role in driving the rotating body 102 to rotate.

[0035] As shown in Figure 6 , Figure 9As shown, the excluding mechanism 3 comprises a pressing assembly 301; the pressing assembly 301 is fixedly connected with the power mechanism 2; the pressing assembly 301 is driven by the power mechanism 2 to make reciprocating motion close to and away from the guide needle sorting mechanism 1 and to exclude the bad guide needle 6.

[0036] Further, the lower end surface of the pressing assembly 301 comprises a groove 3011, an abutting surface 3012 and a through hole 3013; the top of the groove 3011 is the abutting surface 3012, and the through hole 3013 is arranged at the center of the abutting surface 3012 and used for passing the guide needle 6.

[0037] The rotating body fixing frame 101 comprises a rotating body top cover 1012, wherein the rotating body top cover is provided with a power rod guide hole 1013; one end of the power connecting rod 202 is slidably penetrated into the power rod guide hole 1013, and the part of the power connecting rod 202 penetrating through the power rod guide hole 1013 is matched and connected with the power guide wheel vertical slot 1021 in the rotating body 102; one side of the rotating body top cover 1012 is connected with the guide needle leading block 1011, and the needle leading block 1011 is fixedly connected with the flat conveying 402.

[0038] Specifically, the power of the excluding mechanism 3 is derived from the power mechanism 2, one side of the pressing assembly 301 is fixedly connected with the power connecting rod 202, and one end of the power connecting rod 202 is slidably penetrated into the power rod guide hole 1013 to play a guiding and positioning role. The pressing assembly 301 is provided with a tension spring positioning pin 206 on the outside; the tension spring positioning pin 206 is provided with a tension spring 205, which is used for the return of the pressing assembly 301.

[0039] The recess 3011 of the lower end surface of the pressing assembly 301 falls vertically into the minute needle positioning groove 10511 in the minute needle rotating disc 1051, wherein the through hole 3013 in the center of the abutting surface 3012 vertically projects and aligns with the guide needle 6 on the minute needle positioning groove 10511. A convex ring 3014 with the same center as the through hole 3013 is arranged outside the through hole 3013, and the convex ring 3014 is exposed on the abutting surface 3012. The convex ring 3014 is used to prevent the end of the inclined needle, the bent needle, and the disordered needle from being inserted into the through hole 3013, thereby improving the accuracy of screening. When the power mechanism 2 outputs power to drive the power connecting rod 202 to perform up-down telescopic movement, the power connecting rod 202 drives the pressing assembly 301 to approach or move away from the minute needle positioning groove 10511, thereby performing unqualified rejection on the guide needle 6 in the minute needle positioning groove 10511. When the pressing assembly 301 is pressed to the position where the top of the guide needle 6 in the minute needle positioning groove 10511 is in contact with the pressing assembly 301, if the top of the guide needle 6 can just pass through the through hole 3013 in the pressing assembly 301, it means that the guide needle 6 is not pushed away, indicating that the guide needle 6 is flawless and is a qualified product. If the top of the guide needle 6 cannot pass through the through hole 3013 in the pressing assembly 301, it means that the guide needle 6 is bent, inclined, or disordered, or has multiple needles. At this time, the defective guide needle 6 will be pressed by the abutting surface 3012 of the pressing assembly 301, forcing the defective guide needle 6 to fall from the minute needle positioning groove 10511, thereby excluding the defective product and preventing the defective product from entering the next station.

[0040] As shown in Figure 5 , Figure 7 , the rotating body 102 is internally provided with a rotating body 102; in this embodiment, the rotating body 102 is a columnar body structure, and the rotating body 102 is provided with a rotating shaft 104 for rotating the rotating body 102 around the axis; the rotating body 102 is provided with an axis hole, and the rotating shaft 104 is arranged in the axis hole. In this embodiment, the rotating body 102 rotates around the rotating shaft 104, and in other embodiments, the rotating body 102 and the rotating shaft 104 can also rotate together as a whole.

[0041] The rotating body 102 is sleeved with a rotating cylinder 105; a gap is reserved between the outer periphery of the rotating body 102 and the inner periphery of the rotating cylinder 105 for the movement of the power connecting rod 202 and the rotation of the rotating cylinder 105. The outer periphery of the rotating cylinder 105 is provided with a minute needle rotating disc 1051 for adsorbing the guide needle 6, wherein a plurality of minute needle positioning grooves 10511 are arranged at intervals in the circumferential direction outside the minute needle rotating disc 1051, and an adsorption body 10512 is arranged inside the minute needle positioning groove 10511 for adsorbing the guide needle 6.

[0042] Specifically as Figure 4As shown, the outer circumferential diameter of the minute hand rotating disc 1051 is greater than the diameter of the rotating cylinder 105, and the minute hand rotating disc 1051 forms a protruding structure outside the rotating cylinder 105. The minute hand rotating disc 1051 is provided with a plurality of minute needle positioning grooves 10511 outside the circumferential direction, wherein the shape and size of the minute needle positioning groove 10511 are matched with the shape of the guide needle 6, the minute needle positioning groove 10511 is used to accommodate the guide needle, the size of the minute needle positioning groove 10511 can be adjusted according to the size of the model to be sorted guide needle 6, and only one guide needle 6 can be accommodated in the minute needle positioning groove 10511 each time, avoiding the phenomenon of multiple needles or disorder, and playing a sorting role. In some other embodiments, a sensor can also be provided to detect whether the guide needle 6 is adsorbed in the minute needle positioning groove 10511, so as to avoid the phenomenon of missing needle, and the minute needle positioning groove 10511 is provided with an adsorbing body 10512 for sucking the guide needle 6, which is used to suck the guide needle 6, so that the guide needle 6 is fixed in the minute needle positioning groove 10511 and rotates with the minute hand rotating disc 1051. The type of adsorbing body 10512 is not limited, and in this embodiment, the adsorbing body 10512 adopts a magnet, and in other embodiments, the adsorbing body 10512 can also adopt a vacuum suction cup to suck the guide needle 6, so that the guide needle 6 is fixed in the minute needle positioning groove 10511.

[0043] The upper end of the rotating body 102 is rotatably connected with the rotating body fixing frame 101 through the rotating shaft 104; the rotating body 102 makes intermittent circumferential motion around the shaft under the driving of the power mechanism 2. The rotating body 102 drives the rotating cylinder 105 and the minute needle positioning groove 10511 to make intermittent rotation under the driving of the power mechanism 2, and the rotating cylinder 105 drives the guide needle 6 to advance one station each time.

[0044] As shown in Figure 5 , Figure 8 , a plurality of power guide wheel vertical grooves 1021 for vertical sliding of the power guide wheel 203 are formed on the outer circumferential side of the rotating body 102; a plurality of power guide wheel inclined grooves 1022 for transverse sliding of the power guide wheel 203 are formed on the outer circumferential side of the rotating body 102 close to the middle; the power guide wheel vertical grooves 1021 and the power guide wheel inclined grooves 1022 intersect and pass through to form a group.

[0045] Specifically, the number of the power guide wheel vertical grooves 1021 spaced apart on the outer circumferential side of the rotating body 102 is set according to actual needs, and the size of the power guide wheel vertical grooves 1021 is matched with the outer diameter of the power guide wheel 203. When the mechanism operates, the power guide wheel 203 is driven by the power connecting rod 202 to slide downward or upward along the power guide wheel vertical grooves 1021, and the power guide wheel vertical grooves 1021 play a guiding role for the power connecting rod 202 and the power guide wheel 203. The upper end of the rotating body 102 is provided with a power guide wheel return groove 1023, and the power guide wheel return groove 1023 is connected with the end of the power guide wheel vertical groove 1021. It is used for limiting and guiding the power guide wheel 203.

[0046] As Figure 7 , Figure 8 shown, the power guide wheel vertical groove 1021 on the outer circumferential side of the rotating body 102 intersects with the power guide wheel inclined groove 1022, and a guide block 103 is arranged at the intersection for guiding the travel direction of the power guide wheel 203.

[0047] Further, the guide block 103 comprises a return elastic member 1031, a pressing block 1032, a pin shaft 1033, and a wedge-shaped part 1034. The pressing block 1032 is in elastic contact with the return elastic member 1031. The wedge-shaped part 1034 swings up and down around the pin shaft 1033 as the fixed point to control the switching of the travel trajectory of the power guide wheel 203 in the power guide wheel vertical groove 1021 and the power guide wheel inclined groove 1022.

[0048] The power guide wheel inclined groove 1022 for the lateral sliding of the power guide wheel 203 is arranged near the middle of the outer circumferential side of the rotating body 102, and the power guide wheel vertical groove 1021 and the power guide wheel inclined groove 1022 intersect and pass through. When the mechanism is running, the power connecting rod 202 drives the power guide wheel 203 to slide downward along the power guide wheel vertical groove 1021, and when the power guide wheel 203 reaches the end of the downward sliding along the power guide wheel vertical groove 1021, the power connecting rod 202 drives the power guide wheel 203 to slide upward along the power guide wheel vertical groove 1021. Under the blocking and guiding action of the guide block 103, the sliding direction of the power guide wheel 203 changes, forcing the power guide wheel 203 to slide into the power guide wheel inclined groove 1022. Since the power guide wheel inclined groove 1022 is an inclined groove with an inclination angle, under the driving of the power mechanism 2, the power connecting rod 202 drives the power guide wheel 203 to slide along the power guide wheel inclined groove 1022, and under the interaction force, the rotating body 102 is forced to rotate around the axis, until the power guide wheel 203 slides out of the other end of the power guide wheel inclined groove 1022, and the rotating cylinder body 105 completes one rotation, and the minute hand positioning groove 10511 drives the guide needle 6 to advance one station each time the rotating cylinder body 105 rotates once. The above-mentioned actions will be repeated when the mechanism is running, realizing the sorting and transferring of the guide needle 6.

[0049] In cooperation with the ejection mechanism 3, the downward pressing assembly 301 ejects the defective guide needle 6 in the minute hand positioning groove 10511. The downward pressing assembly 301 follows the screening of the guide needle 6 in the minute hand positioning groove 10511 once each time the rotating cylinder body 105 rotates once. The sorting and ejection of the defective guide needle 6 are carried out simultaneously, improving the efficiency and realizing non-destructive sorting. The risk of ejecting the curved needle, multiple needles and inclined needles is eliminated, and the precision of screening the defective is improved.

[0050] As Figure 1 , Figure 2As shown, a feeding mechanism 4 is provided on one side of the needle sorting mechanism 1; the feeding mechanism 4 includes a vibratory plate 401 for loading the needles 6 to be sorted; a horizontal conveyor 402 for transferring the needles 6, wherein a vibrator 403 is provided below the horizontal conveyor 402; the output end of the horizontal conveyor 402 is connected to the needle sorting mechanism 1. The needles 6 to be sorted are supplied by the vibratory plate 401, and the needles 6 are conveyed to the needle sorting mechanism 1 by the horizontal conveyor 402, ensuring continuous feeding.

[0051] like Figure 1 , Figure 2 As shown, a guide needle transfer mechanism 5 is provided at the lower station on one side of the guide needle sorting mechanism 1; wherein the guide needle transfer mechanism 5 includes a needle suction head 5011 for picking up the guide needle 6 in the needle positioning groove 10511; a rotating arm 5012 for driving the needle suction head 5011 to rotate; and a needle support track 502 that matches and docks with the rotating arm 5012.

[0052] Specifically, after being sorted by the guide needle sorting mechanism 1 and the defective needles are removed by the rejection mechanism 3, the good single guide needle 6 will be picked up from the needle positioning groove 10511 by the needle suction head 5011 in the guide needle transfer mechanism 5, and then moved to the needle support track 502 by the rotating arm 5012. The guide needle 6 will then enter the next station for further processing.

[0053] It should be emphasized that the embodiments described in this invention are illustrative rather than limiting. Therefore, this invention is not limited to the embodiments described in the specific implementation. Any other implementation methods derived by those skilled in the art based on the technical solutions of this invention also fall within the scope of protection of this invention.
