As shown in fig. 14, as a partial structure diagram of the first vibration plate 1, the vibration feeding track includes a horizontal clip feeding track and a vertical clip feeding track, the horizontal clip feeding track includes a supporting wall 407 and a side wall 404, in order to form a good supporting and limiting effect on the clip, a continuous supporting and limiting structure is provided on the supporting wall 407, the supporting and limiting structure in this embodiment is a supporting and limiting groove 401 provided on the supporting wall 407, the supporting and limiting groove 401 is V-shaped, and can support and limit the outer conical surface of the clip, so as to ensure that the clip can be stably conveyed forward, so that the clip is not easily vibrated off, and the clip which is not supported by the supporting and limiting groove 401 easily shakes off from the track and falls into the vibration plate again, and the extending directions of the supporting and limiting groove 401 and the supporting wall 407 are consistent, so that the big end or the small end of the clip can move forward.
Along the moving direction of the clamping piece 5, a blocking plate 402, a transition beam 403, a fixed baffle 405, a movable baffle 409 and a groove 406 are sequentially arranged on the horizontal clamping piece feeding track, wherein one end of the blocking plate 402 is fixed on the side wall 404, the other end of the blocking plate is overhanging, the blocking plate 402 is horizontally arranged, and the distance from the blocking plate 402 to the supporting wall 407 is smaller than the length of the clamping piece, so that the vertical clamping piece cannot pass through the blocking plate 402 and can only be blocked by the blocking plate 402 to fall into the vibration disk, as shown in fig. 22, or is blocked to be in a horizontal posture, and the horizontal clamping piece can be continuously conveyed forwards through the blocking plate 402. Thus, the vertical clamping piece is removed, or the horizontal clamping piece is screened out.
The transition beam 403 is disposed downstream of the blocking plate 402, and the transition beam 403 is a portion of the supporting wall 407, which has a width smaller than the groove width of the clip groove, and is equivalent to a section of relatively narrow supporting wall, and the length of the transition beam 403 is greater than the clip length L, so that when the clip with the internal thread facing upward passes through the transition beam 403, the clip can be supported and continuously transported under the action of the supporting and limiting groove 401, as shown in fig. 14. While the clip with the internal thread facing downwards passes through the transition beam 403, it initially "rides" on the transition beam 403, but easily rotates around the transition beam 403 to slide off under vibration, as shown in fig. 22. Even if individual clips can smoothly ride over the transition beam 403, they will collide with the end surface of the next support wall (i.e., the stop surface 408) and fall off as the forward motion continues. Thus, the clamping piece with the internal thread facing upwards is screened out.
One end of the fixed baffle 405 is fixed on the side wall 404, the other end is overhanging, the movable baffle 409 is mounted on the fixed baffle 405 in a guiding way along the up-down direction, and the fixed baffle 405 is provided with a guiding hole for guiding the movable baffle 409 up and down. As shown in fig. 23, in a matching manner of the fixed baffle and the movable baffle, the guide hole on the fixed baffle 405 is a blind hole with a downward hole, a spring 415 is disposed between the bottom of the guide hole and the movable baffle 409, one end of the spring 415 is fixed on the bottom of the guide hole, the other end of the spring 415 is fixed on the movable baffle 409, the movable baffle 409 is hoisted on the fixed baffle 405 through the spring 415, and when the movable baffle 409 receives an upward force, the spring 415 can be compressed to move upward.
The moving baffle 409 includes a material-facing surface 4091 that is obliquely disposed against the incoming material direction, and before the incoming material, the distance between the bottom end of the material-facing surface 4091 and the supporting wall 407 is smaller than the height h of the big end of the clamping piece, so that when the big end is forward of the clamping piece, the big end is higher and can collide with the obliquely disposed material-facing surface 4091, and then guided to slide from the feeding track under the vibration effect. Meanwhile, the distance between the bottom end of the material-facing surface 4091 and the supporting wall 407 is larger than the height of the small end of the clamping piece, so that when the small end faces forward, the clamping piece can drill into the lower part of the movable baffle 409 due to the fact that the small end is lower, and the section of the clamping piece is in an inclined state when the clamping piece lies flat, as the clamping piece continues to move forward, the section of the clamping piece can apply upward acting force to the movable baffle 409 to force the movable baffle 409 to compress the spring 415 to move upward, and finally the clamping piece can pass through the movable baffle 409 and then the movable baffle 409 is reset under the action of the spring reaction force.
In addition, the side face of the fixed baffle 405 facing the feeding direction is an inclined face 4051, the inclined face 4051 is parallel to the feeding face 4091, and a set distance is provided between the fixed baffle 405 and the supporting wall 407, so that a part of clips with front large ends and two sections not at the same height, namely clips with two sections with a high section and a low section and the whole large end with a higher section, directly collide on the inclined face 4051, and are guided down by the inclined face 4051 without guiding down by moving the baffle 409.
The arrangement of the inclined surface 4051 is equivalent to sharing a part of the responsibility of the movable baffle 409, so that the height of the fixed baffle 405 is not too high, and further, the length of the movable baffle 409 is not too long, otherwise, if the clamping piece is blocked by only the movable baffle 409, the fixed baffle 405 needs to be higher, and then the movable baffle 409 needs to be longer, so that the weight of the movable baffle 409 is increased, which is not beneficial to the upward movement of the movable baffle 409, and even the situation that the clamping piece cannot jack up the movable baffle 409 occurs.
With vibration dish self as the reference object, the clamping piece is the forward movement, then vertical clamping piece pay-off track setting just is parallel with it on horizontal clamping piece pay-off track's right side, as shown in fig. 21, vertical clamping piece pay-off track is including being used for supporting clamping piece big end terminal surface's holding surface 413, and two perpendicular to holding surface 413 setting are used for preventing vertical clamping piece pivoted spacing lateral wall, two spacing lateral walls are interior spacing lateral wall 412 and outer spacing lateral wall 411 respectively, spacing between interior spacing lateral wall 412 and the outer spacing lateral wall 411 and clamping piece big end's high phase-match.

The length of the groove 406 is smaller than the length L of the clip 12, and the front and rear sides of the groove 406 are provided with the supporting and limiting grooves 401, so when the clip with the small end forward moves to the position of the groove 406, as shown in fig. 16, the small end of the clip can cross the groove 406 due to the rear gravity center of the clip, and at a certain moment, the clip spans the groove, and the large end and the small end of the clip are both supported on the supporting and limiting grooves 401.
As shown in fig. 17, as the clip continues to move forward, its large end is suspended above the groove, and because of the unstable center of gravity, its large end falls into the groove to be in an inclined state, at this time, the large end of the clip is supported by the bottom support wall 4061, and the outer conical surface of the clip is supported by the side support wall 4062. The recess 406 also includes a stop wall 4063 opposite the side support wall 4062, the stop wall 4063 stopping the clip's butt end.
The bottom support wall 4061 is gradually inclined toward the support surface 413 from top to bottom and is connected to the support surface 413 such that the clip falling into the recess slides down the bottom support wall 4061 under its own weight. As shown in fig. 15, a transition guide wall 414 is disposed between the inner limiting side wall 412 and the side supporting wall 4062, and the transition guide wall 414 is an arc-shaped wall, and can guide the sliding clip to transition onto the supporting surface 413, as shown in fig. 14, which is equivalent to guiding the clip to turn.
The outer limiting side wall 411 and the stop wall 4063 are also in cambered surface transition, so that the transition of the clamping piece to the supporting surface 413 is facilitated, and in order to prevent the clamping piece from falling off the vertical clamping piece feeding track in the process of transition to the supporting surface 413, an upturning edge 410 which is turned upwards is arranged at the top of the position, opposite to the transition guide wall 414, of the outer limiting side wall 411, the upturning edge 410 extends towards the groove and is arc-shaped, the upturning edge 410 and the transition guide wall 414 are mutually matched, and the large end of the clamping piece can be prevented from falling off the vertical clamping piece feeding track in the turning process, as shown in fig. 18 and 19.
As the clip moves further, the clip gradually becomes a vertical posture on the support surface 413 due to the matching of the distance between the inner limit side wall 412 and the outer limit side wall 411 with the height of the clip large end, and the orientation of the notch is uniform as shown in fig. 20 and 21. It should be noted that, through the reasonable design of the vibrating disk structure, the notches of the clamping pieces output by the first vibrating disk 1 and the second vibrating disk 2 are arranged oppositely, and the structural principles of preventing the vertical clamping pieces from passing through, preventing the internal threads from passing through downwards, preventing the big end from passing through forwards and converting from horizontal to vertical are the same.
