Before the nailing and coiling process, the guide pins must be strictly sorted to eliminate defective products. However, the existing guide pin sorting mechanism does not have the function of automatically sorting and rejecting bent guide pins. It mainly uses steel sheet needle blocks and steel wires at the front end of the horizontal feeding track of the guide pin feeding mechanism to separate the needles.

"Part A" and "Part B" are industry-specific designations for the structural names of the leads, which are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention. Example

[0030] A guide needle non-destructive sorting mechanism, comprising a guide needle sorting mechanism 1, a power mechanism 2, and an exclusion mechanism 3; the exclusion mechanism 3 is arranged above the guide needle sorting mechanism 1; the power mechanism 2 is arranged above the exclusion mechanism 3; a feeding mechanism 4 is arranged on one side of the guide needle sorting mechanism 1; a rotating body 102 is arranged inside the guide needle sorting mechanism 1; a rotating shaft 104 for the rotating body 102 to rotate around the axis is arranged in the axial direction of the rotating body 102; a rotating cylinder 105 is sleeved on the outer periphery of the rotating body 102; the rotating cylinder 105 The outer side is provided with a minute hand turntable 1051 for adsorbing the guide needle 6; the upper end of the rotating body 102 is rotatably connected to the rotating body fixing frame 101 through the rotating shaft 104; the rotating body 102 performs intermittent circular motion around the axis driven by the power mechanism 2; the removal mechanism 3 includes a pressing component 301; the outer side of the pressing component 301 is fixedly connected to the power mechanism 2; the pressing component 301 is driven by the power mechanism 2 to perform reciprocating motion close to and away from the guide needle sorting mechanism 1 and remove the defective guide needle 6.

[0031] Specifically, an exclusion mechanism 3 is arranged above the guide needle sorting mechanism 1; a power mechanism 2 is arranged above the exclusion mechanism 3, and the operating power of the guide needle sorting mechanism 1 and the exclusion mechanism 3 is provided by the power mechanism 2. The guide needle 6 to be sorted is pushed to the guide needle sorting mechanism 1 through the horizontal feed 402, and the power mechanism 2 drives the rotating body 102 to rotate through the minute hand positioning groove 1051 on the minute hand turntable 1051 on the outer peripheral side of the rotating cylinder 105 to absorb a single guide needle 6 and then rotate. At the same time, the exclusion mechanism 3 is pressed down to exclude the defective guide needles through the pressing assembly 301. The qualified guide needles 6 will enter the needle suction station driven by the rotating cylinder 105, and the needle suction head 5011 sucks and transfers them to the needle support track 502 in the guide needle transfer mechanism 5. After the above process, the guide needle 6 is sorted. The guide needle sorting mechanism 1 and the exclusion mechanism 3 are effectively combined to sort the guide needle 6 without loss. The rotating body 102 and the minute hand positioning groove 10511 are set to rotate alternately in multiple stations to achieve the distribution and transfer of a single needle at each station, effectively avoiding the occurrence of missing needles or multiple needles. The minute hand positioning groove 10511 and the adsorbent 10512 are set to avoid contact between components. The guide needle 6 is damaged by collision and non-destructive sorting is achieved. The groove 3011 in the exclusion mechanism 3 is set in combination with the through hole to eliminate the risk of bent needles, multiple needles and oblique needles, thereby improving the accuracy of screening out poor quality.

[0032] like Figure 3 , Figure 6 , Figure 7 As shown, 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 to the power connecting rod 202; the power connecting rod 202 is slidably installed on the power rod fixing frame 204; and a power guide wheel 203 is provided at one end of the power connecting rod 202 away from the power driver 201.

[0033] Specifically, in this embodiment, the power driver 201 adopts a power cylinder. In other embodiments, the power driver 201 may also adopt a motor or other power structure that can drive the power connecting rod 202 to perform upward and downward telescopic movements. The output end of the power driver 201 is connected to the power connecting rod 202. A power guide wheel 203 is provided at one point of the power connecting rod 202. When the power driver 201 outputs power, the power connecting rod 202 drives the power guide wheel 203 to move. 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, thereby driving the rotating body 102 to rotate.

[0034] like Figure 6 , Fig. 9As shown, the removal mechanism 3 includes a pressing component 301; the outer side of the pressing component 301 is fixedly connected to the power mechanism 2; the pressing component 301 is driven by the power mechanism 2 to make a reciprocating motion close to and away from the guide needle sorting mechanism 1 and remove the defective guide needles 6.

[0035] Furthermore, the lower end surface of the pressing component 301 includes a groove 3011, an abutting surface 3012, and a through hole 3013; wherein the top of the groove 3011 is the abutting surface 3012, and a through hole 3013 for passing the guide needle 6 is opened at the center of the abutting surface 3012.

[0036] The rotating body fixing frame 101 includes a rotating body top cover 1012, in which a power rod guide hole 1013 is provided; wherein one end of the power connecting rod 202 slides through the power rod guide hole 1013, and the part of the power connecting rod 202 passing through the power rod guide hole 1013 matches and docks with the vertical groove 1021 of the power guide wheel in the rotating body 102; one side of the rotating body top cover 1012 is connected to the guide needle lead-out block 1011, and the needle lead-out block 1011 is fixedly connected to the horizontal feed 402.

[0037] Specifically, the power of the removal mechanism 3 comes from the power mechanism 2, one side of the pressing component 301 is fixedly connected to the power connecting rod 202, and one end of the power connecting rod 202 slides through the power rod guide hole 1013 to play a guiding and positioning role. A tension spring positioning pin 206 is arranged on the outside of the pressing component 301; a tension spring 205 is arranged in the tension spring positioning pin 206 to return the pressing component 301.

[0038] The vertical projection of the groove 3011 on the lower end surface of the pressing component 301 falls on the minute hand positioning groove 10511 in the minute hand rotating disk 1051, wherein the vertical projection of the through hole 3013 at the center of the abutting surface 3012 is aligned and overlapped with the guide pin 6 on the minute hand positioning groove 10511. A convex ring 3014 coaxial with the through hole 3013 is arranged on the outer side of 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 ends of oblique needles, bent needles, and disordered needles 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 upward and downward telescopic movement, the power connecting rod 202 drives the pressing component 301 to approach or move away from the minute hand positioning groove 10511, and the guide pin 6 in the minute hand positioning groove 10511 is rejected. When the pressing component 301 is pressed down to the position in contact with the top of the guide pin 6 in the minute hand positioning groove 10511, if the top of the guide pin 6 can just pass through the through hole 3013 in the pressing component 301, the guide pin 6 is not pushed away, indicating that the guide pin 6 is flawless and is a qualified product. If the top of the guide pin 6 fails to pass through the through hole 3013 in the pressing component 301, it means that the guide pin 6 is bent, tilted, or has disordered or multiple pins. At this time, the defective guide pin 6 will be squeezed by the abutting surface 3012 of the pressing component 301, forcing the defective guide pin 6 to fall from the minute hand positioning groove 10511, thereby eliminating the defective and preventing the defective product from entering the next station.

[0039] like Figure 5 , Figure 7 As shown, a rotating body 102 is arranged inside the guide needle sorting mechanism 1; in the present embodiment, the rotating body 102 is a columnar structure, and a rotating shaft 104 is arranged in the axial direction of the rotating body 102 for the rotating body 102 to rotate around the axis; the rotating body 102 is provided with an axial hole at the axis, and the rotating shaft 104 is arranged in the axial hole. In the present 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.

[0040] The outer periphery of 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 hand rotating disc 1051 for adsorbing the guide needle 6, wherein a plurality of minute hand positioning grooves 10511 are arranged at intervals on the outer side of the minute hand rotating disc 1051 in the circumferential direction, wherein an adsorbent 10512 for absorbing the guide needle 6 is arranged inside the minute hand positioning groove 10511.

[0041] Specific as Figure 4As shown, the outer diameter of the minute hand rotating disc 1051 is larger than the diameter of the rotating cylinder 105, and the minute hand rotating disc 1051 forms a convex structure on the outer side of the rotating cylinder 105. A plurality of minute hand positioning grooves 10511 are arranged at intervals on the outer side of the minute hand rotating disc 1051 in the circumferential direction, wherein the shape and size of the minute hand positioning grooves 10511 match the shape of the guide needle 6, and the minute hand positioning grooves 10511 are used to accommodate the guide needles. The size of the minute hand positioning grooves 10511 can be adjusted according to the size of the guide needles 6 to be sorted, and the minute hand positioning grooves 10511 can only accommodate one guide needle 6 at a time, so as to avoid the phenomenon of multiple needles or disordered needles and play a sorting role. In some other embodiments, a sensor may be provided to detect whether the guide needle 6 is adsorbed in the minute hand positioning groove 10511 to avoid the needle shortage phenomenon. In addition, an adsorbent 10512 for adsorbing the guide needle 6 is provided in the minute hand positioning groove 10511 to adsorb the guide needle 6 so that the guide needle 6 is fixed in the minute hand positioning groove 10511 and rotates with the minute hand rotating disk 1051. The type of the adsorbent 10512 is not limited. In this embodiment, the adsorbent 10512 is a magnet. In other embodiments, the adsorbent 10512 may also be adsorbed by a vacuum suction cup so that the guide needle 6 is fixed in the minute hand positioning groove 10511.

[0042] The upper end of the rotating body 102 is rotatably connected to the rotating body fixing frame 101 through the rotating shaft 104; the rotating body 102 performs intermittent circular motion around the axis driven by the power mechanism 2. The rotating body 102 drives the rotating cylinder 105 and the minute hand positioning groove 10511 to perform intermittent rotation under the drive of the power mechanism 2. Every time the rotating cylinder 105 rotates once, the minute hand positioning groove 10511 drives the guide needle 6 to move forward one station.

[0043] like Figure 5 , Figure 8 As shown, a plurality of power guide wheel vertical grooves 1021 for vertical sliding of the power guide wheel 203 are provided on the outer peripheral side surface of the rotating body 102; a plurality of power guide wheel inclined grooves 1022 for horizontal sliding of the power guide wheel 203 are provided near the middle of the outer peripheral side surface of the rotating body 102; the power guide wheel vertical grooves 1021 and the power guide wheel inclined grooves 1022 are cross-connected to form a group.

[0044] Specifically, the number of the power guide wheel vertical grooves 1021 spaced apart on the outer peripheral side of the rotating body 102 is set according to actual needs, and the size of the power guide wheel vertical grooves 1021 matches the outer diameter of the power guide wheel 203. When the mechanism is running, the power connecting rod 202 drives the power guide wheel 203 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, which is connected to the end of the power guide wheel vertical groove 1021. It is used for the limiting and guiding role of the power guide wheel 203.

[0045] like Figure 7 , Figure 8 As shown, a guide block 103 for guiding the travel direction of the power guide wheel 203 is provided at the intersection of the power guide wheel vertical groove 1021 and the power guide wheel inclined groove 1022 on the outer peripheral side of the rotating body 102.

[0046] Furthermore, the guide block 103 includes a return elastic member 1031, a pressure block 1032, a pin shaft 1033, and a wedge-shaped portion 1034; wherein the pressure block 1032 is in elastic contact with the return elastic member 1031; the wedge-shaped portion 1034 swings up and down with the pin shaft 1033 as a 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.

[0047] A power guide wheel inclined groove 1022 for the power guide wheel 203 to slide horizontally is provided near the middle of the outer peripheral side of the rotating body 102, and the power guide wheel vertical groove 1021 crosses and penetrates the power guide wheel inclined groove 1022. When the mechanism is running, the power connecting rod 202 drives the power guide wheel 203 to slide down along the power guide wheel vertical groove 1021. When the power guide wheel 203 finishes sliding down 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 bevel groove 1022 is an inclined groove with an inclined angle, under the drive of the power mechanism 2, the power connecting rod 202 drives the power guide wheel 203 to slide along the power guide wheel bevel groove 1022, and the rotating body 102 is forced to rotate around the axis under the interaction force until the power guide wheel 203 slides out from the other end of the power guide wheel bevel groove 1022, and the rotating body 102 and the rotating cylinder 105 complete a rotation. Every time the rotating cylinder 105 rotates once, the minute hand positioning groove 10511 drives the guide needle 6 to move forward one workstation. When the mechanism is operating, the above actions will be repeated to realize the sorting and transfer of the guide needle 6.

[0048] The pressing component 301 of the elimination mechanism 3 is used to remove the defective guide pins 6 in the minute hand positioning groove 10511. Each time the rotating cylinder 105 rotates, the pressing component 301 follows to screen the guide pins 6 in the minute hand positioning groove 10511. The selection and removal of the defective guide pins 6 are carried out simultaneously, which improves the efficiency and realizes non-destructive sorting. The risks of bent needles, multiple needles and oblique needles are eliminated, and the accuracy of screening out the defective ones is improved.

[0049] like Figure 1 , Figure 2As shown, a feeding mechanism 4 is provided on one side of the guide needle sorting mechanism 1; the feeding mechanism 4 includes a vibration plate 401 for loading the guide needles 6 to be sorted; a horizontal conveyor 402 for transferring the guide needles 6, wherein a vibrator 403 is provided below the horizontal conveyor 402; and the output end of the horizontal conveyor 402 is connected to the guide needle sorting mechanism 1. The guide needles 6 to be sorted are supplied by the vibration plate 401, and the guide needles 6 are transported to the guide needle sorting mechanism 1 by the horizontal conveyor 402 to ensure continuous feeding.

[0050] like Figure 1 , Figure 2 As shown, a guide needle transfer mechanism 5 is provided at the lower workstation on one side of the guide needle sorting mechanism 1; wherein the guide needle transfer mechanism 5 includes a needle suction head 5011 for sucking the guide needle 6 in the minute hand positioning groove 10511; and a rotating arm 5012 for driving the needle suction head 5011 to flip; and a needle support track 502 that matches and docks with the rotating arm 5012.

[0051] Specifically, the guide needle 6 is sorted by the guide needle sorting mechanism 1 and the defective ones are eliminated by the elimination mechanism 3, and finally a single good guide needle 6 is obtained, which will be sucked from the minute hand positioning groove 10511 by the suction head 5011 in the guide needle transfer mechanism 5, and transferred to the needle support track 502 under the drive of the rotating arm 5012, and the guide needle 6 will enter the next workstation for further processing.

[0052] It should be emphasized that the embodiments described in the present invention are illustrative rather than restrictive, and therefore the present invention is not limited to the embodiments described in the specific implementation manners. Any other implementation manners derived by those skilled in the art based on the technical solutions of the present invention also fall within the scope of protection of the present invention.
