Detailed Description

An embodiment of an automatic clip placing system of the invention is shown in fig. 3-5, the automatic clip placing system in the embodiment is used for placing halved clips, the placed clips are used for carrying out heat treatment in a centralized manner, the automatic clip placing system comprises a vibration feeding device for conveying the clips, the vibration feeding device in the embodiment is a vibration disk, the vibration disks are four in number, and are respectively a first vibration disk 1, a second vibration disk 2, a third vibration disk 3 and a fourth vibration disk 4, wherein the first vibration disk 1 and the third vibration disk 3 are arranged in the front-back direction, the second vibration disk 2 and the fourth vibration disk 4 are also arranged in the front-back direction, and the first vibration disk 1 and the third vibration disk 3 are respectively positioned at the left side of the second vibration disk 2 and the fourth vibration disk 4. Through the structural design of the vibration discs, the clamping pieces 12 finally output by each vibration disc are in a vertical posture that the small heads face upwards and the notches face backwards.

Taking the fourth vibration disk 4 as an example, a spiral vibration feeding track is arranged on the fourth vibration disk 4, and the vibration feeding track is used for supporting the clamping pieces 12 and driving the clamping pieces to move forwards and spirally rise under the vibration effect. As shown in fig. 9, which is a partial structure diagram of the fourth vibration tray 4, the vibration feeding rails include a horizontal clip feeding rail and a vertical clip feeding rail, the horizontal clip feeding rail includes a supporting wall 407 and a side wall 404, in order to form a good supporting and limiting effect for the clips, the supporting wall 407 is provided with a continuous supporting and limiting structure, the supporting and limiting structure in this embodiment is a supporting and limiting groove 401 formed 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 smoothly conveyed forward, so that the clip is not easily shaken off, the clamping pieces which are not supported by the supporting and limiting grooves 401 are easy to shake off the track and fall into the vibration disc again, and the extending directions of the supporting and limiting groove 401 and the supporting wall 407 are consistent, so that the large head end or the small head end of the clip can move forward.

Along the moving direction of the clips 12, 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 clip 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 suspended, the blocking plate 402 is horizontally arranged, and the distance from the blocking plate 402 to the supporting wall 407 is smaller than the clip length L, so that the vertical clips cannot pass through the blocking plate 402 and can only be blocked by the blocking plate 402 and fall into the vibration disc, as shown in fig. 18, or can be blocked and fall into a horizontal posture, and the horizontal clips can continue to be conveyed forwards through the blocking plate 402. Thus, the vertical clamping pieces are rejected, or the horizontal clamping pieces are screened out.

A transition beam 403 is arranged downstream of the stop plate 402, the transition beam 403 is part of a support wall 407, the width of the transition beam is smaller than the groove width a of the clip groove, corresponding to a section of a narrower support wall, and the length of the transition beam 403 is greater than the clip length L, so that when the clip with the upward internal thread passes through the transition beam 403, the clip can be supported and transported further under the action of the support and limit groove 401, as shown in fig. 9. The clip with the downward internal thread initially "rides" on the transition beam 403 as it passes over the transition beam 403, but is easily rotated around the transition beam 403 by vibration to slide off as shown in fig. 18. Even if there are individual clips that "ride" smoothly on the transition beam 403, they will collide with the end surface of the next section of support wall (i.e., stop surface 408) and fall out as the forward motion continues. Thus, the clamping piece with the upward internal thread is screened out.

One end of the fixed baffle 405 is fixed on the side wall 404, the other end of the fixed baffle is suspended, the movable baffle 409 is installed on the fixed baffle 405 in a vertically guiding and moving manner, and a guide hole for the movable baffle 409 to vertically guide and move is formed in the fixed baffle 405. As shown in fig. 19, a matching form of the fixed baffle and the movable baffle is shown, a guide hole on the fixed baffle 405 is a blind hole with a downward hole opening, a spring 415 is arranged between the hole bottom of the guide hole and the movable baffle 409, one end of the spring 415 is fixed on the hole bottom of the guide hole, the other end of the spring 415 is fixed on the movable baffle 409, the movable baffle 409 is equivalently hung on the fixed baffle 405 through the spring 415, and when the movable baffle 409 is subjected to an upward acting force, the spring 415 can be compressed to move upwards.

The movable baffle 409 comprises a material facing surface 4091 which is obliquely arranged facing the material feeding direction, and before the material is fed, 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 head end of the clamping piece, so that when the big head end of the clamping piece faces forwards, the big head end is higher and can abut against the material facing surface 4091 which is obliquely arranged, and then the clamping piece is guided to slide off 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 greater than the height of the small head end of the clip, so that when the clip with the small head end facing forward is fed, the small head end is lower and can be drilled below the moving baffle 409, and the section of the clip is in an inclined state when the clip lies flat, so that as the clip continues to move forward, the section 1205 of the clip can apply an upward acting force to the moving baffle 409 to force the moving baffle 409 to compress the spring 415 to move upward, and finally the clip can pass through the moving baffle 409 and then reset under the reaction force of the spring by the moving baffle 409.

In addition, the side of the fixed baffle 405 facing the incoming material direction is the inclined surface 4051, the inclined surface 4051 is parallel to the incoming material surface 4091, and a set distance is provided between the fixed baffle 405 and the supporting wall 407, so that a part of the big head end faces forward, and the two cross sections 1205 are clips not at the same height, that is, the clips with two cross sections 1205 one high and one low and the whole big head end higher will directly abut against the inclined surface 4051, and be guided down by the inclined surface 4051, without being guided down by the movable baffle 409.

The inclined surface 4051 is equivalent to share a part of the responsibility of the movable baffle 409, so that the height of the fixed baffle 405 is not too high, which means that the length of the movable baffle 409 is not too long, otherwise, if the clip is stopped by only the movable baffle 409, the fixed baffle 405 needs to be set to be higher, and then the movable baffle 409 needs to be set to be longer, which causes the weight of the movable baffle 409 to be increased, is not favorable for the upward movement of the movable baffle 409, and even causes the situation that the clip cannot jack the clip.

As shown in fig. 20, another form of the fixed baffle and the movable baffle is shown, the section of the movable baffle 409 ' is T-shaped, the guide hole on the fixed baffle 405 ' is a through hole, the movable baffle 409 ' is directly in guide sliding fit with the fixed baffle 405 ', and at this time, the movable baffle 409 ' falls down by self-weight after being jacked by the clamping piece. Similarly, the material receiving surface 4091 'is provided on the movable shutter 409' and the inclined surface 4051 'is provided on the fixed shutter 405', and the principle is the same as above, and will not be described again here. Therefore, the clamping pieces passing through the fixed baffle and the movable baffle are uniformly in a posture that the internal threads face upwards and the small head ends face forwards.

The vibration disc is used as a reference object, the clamping pieces move forwards, and the vertical clamping piece feeding rail is arranged on the right side of the horizontal clamping piece feeding rail and is parallel to the horizontal clamping piece feeding rail, as shown in fig. 10 and 17, the vertical clamping piece feeding rail comprises a supporting surface 413 for supporting the end surface of the big head end of the clamping piece and two limiting side walls perpendicular to the supporting surface 413 and used for preventing the vertical clamping piece from rotating, the two limiting side walls are an inner limiting side wall 412 and an outer limiting side wall 411 respectively, and the distance between the inner limiting side wall 412 and the outer limiting side wall 411 is matched with the height of the big head end of the clamping piece.

The groove 406 is provided at the end of the horizontal clip feed track, as shown in fig. 11, and the groove 406 includes a bottom support wall 4061 for supporting the big end of the clip and a side support wall 4062 for supporting the outer conical surface of the clip. The length of the groove 406 is less than the length L of the clip 12, and the front and rear sides of the groove 406 are both provided with the support limiting grooves 401, so as shown in fig. 12, when the clip with the small head end facing forward moves to the position of the groove 406, the small head end of the clip can cross over the groove 406 because the gravity center of the clip is back, at a certain moment, the clip spans over the groove, and the large head end and the small head end of the clip are both supported on the support limiting grooves 401.

As shown in fig. 13, as the clip continues to move forward, the big end of the clip will overhang the groove, and because the center of gravity is unstable, the big end of the clip will fall into the groove and be inclined, and at this time, the big 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 walls 4062. The recess 406 also includes a stop wall 4063 opposite the side support wall 4062, the stop wall 4063 stopping the large head end of the clip.

The bottom support wall 4061 is gradually inclined from top to bottom toward the support surface 413 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. 11, a transition guide wall 414 is disposed between the inner limiting sidewall 412 and the side supporting wall 4062, and the transition guide wall 414 is an arc-shaped wall and can guide the downward-sliding clip to transition to the supporting surface 413, which is equivalent to guiding the clip to turn as shown in fig. 14.

The outer limit side wall 411 and the stop wall 4063 are also in arc transition, so that the clip can be favorably transited to the supporting surface 413, and in order to prevent the clip from falling off the vertical clip feeding track in the process of transiting to the supporting surface 413, an upturned edge 410 which is turned upwards is arranged at the top of the outer limit side wall 411 opposite to the transition guide wall 414, the upturned edge 410 extends towards the groove and is in an arc shape, and the upturned edge 410 and the transition guide wall 414 are matched with each other, so that the large head end of the clip can be prevented from falling off the vertical clip feeding track in the turning process, as shown in fig. 14 and 15.

As the clip continues to move, the clip gradually assumes an upright position on the support surface 413 with the notches all facing in the same direction as shown in fig. 16 and 17, since the spacing between the inner and outer retaining

side walls

412, 411 matches the height of the larger end of the clip. It should be noted here that through reasonable design of the structure of the vibration discs, the notches of the clips output by the four vibration discs can all face to the rear side in fig. 4, and the structural principles adopted by each vibration disc for preventing vertical clips from passing through, preventing clips with internal threads facing downward from passing through, preventing clips with large head ends facing forward from passing through, and converting horizontal type to vertical type are the same.

The above is the feed principle of the vibrating disk and the following is a description of the components downstream of the vibrating disk.

The discharge port of each vibration disk is provided with a material conveying groove, namely a first material conveying groove 5 arranged at the discharge port of the first vibration disk 1, a second material conveying groove 6 arranged at the discharge port of the second vibration disk 2, a third material conveying groove 7 arranged at the discharge port of the third vibration disk 3 and a fourth material conveying groove 8 arranged at the discharge port of the fourth vibration disk 4. The four material conveying grooves are arranged in parallel, adjacent material conveying grooves are tightly attached to each other, and each material conveying groove is gradually inclined downwards from left to right, so that the clamping pieces 12 are continuously vibrated out by the vibration disc, and each clamping piece 12 automatically moves rightwards under the action of the inclined surface.

The automatic clamping piece placing system further comprises cross sliding tables 11 arranged at the downstream of the four material conveying grooves, and material receiving discs 10 used for receiving and placing the clamping pieces are placed at the tops of the cross sliding tables 11. As shown in fig. 7 and 8, the cross slide 11 includes a Y-direction moving mechanism 1101 and an X-direction moving mechanism 1109 provided above the Y-direction moving mechanism 1101, where the X-direction is a left-right direction, the Y-direction is a front-back direction, and the X-direction and the Y-direction are perpendicular to each other.

The Y-direction motor mounting frame 1104 is provided with a Y-direction motor 1105 and a Y-direction lead screw 1103 in transmission connection with the Y-direction motor 1105, the Y-direction lead screw 1103 and the Y-direction guide rod 1102 are provided with a Y-direction platform bracket 1107, and a Y-direction platform 1108 is fixed at the top of the Y-direction platform bracket 1107. The Y-direction platform bracket 1107 is slidably guided by the Y-direction guide rod 1102 and is in threaded connection with the Y-direction lead screw 1103, so that when the Y-direction motor 1105 drives the Y-direction lead screw 1103 to rotate, the Y-direction platform bracket 1107 slides back and forth along the Y-direction guide rod 1102 under the action of the lead screw nut principle, and further drives the Y-direction platform 1108 to move back and forth.

The receiving tray 10 is placed on the X-direction platform 1110, and when the X-direction motor 1115 and the Y-direction motor 1105 respectively operate, the receiving tray 10 can move in the left-right direction and the front-back direction respectively to receive materials. The receiving tray 10 is square, the feeding directions of the four material conveying grooves are left and right directions, namely the extending directions of the four material conveying grooves are perpendicular to the extending direction of the left side of the receiving tray 10. The receiving disc 10 is located below the discharge ports of the conveying troughs all the time in the receiving process, and preferably, in order to guarantee stable blanking, the receiving disc 10 is attached to the discharge ports of the conveying troughs, and the inclined angle of each conveying trough is made to be as small as possible on the premise that the clamping pieces can meet the conveying requirements.

The automatic clip placing system further comprises a control device 9 for controlling the operation of the first vibration disc 1, the second vibration disc 2, the third vibration disc 3, the fourth vibration disc 4, the servo motor in the X direction and the servo motor in the Y direction, as shown in fig. 6, the control device 9 comprises an operation panel 91, a controller (not shown in the figure) is arranged in the control device 9, in the embodiment, cameras are arranged near each vibration disc, near each material conveying groove and near the cross sliding table, and are used for collecting real-time video information conveyed by clips and transmitting the real-time video information to the control device 9, and then the control device 9 controls the starting, stopping and operation directions of the components according to the real-time operation information, namely, visual management is adopted.

The working principle of the automatic clamping piece placing system is as follows:

when the vertical type vibration disc conveying device is used, the control device 9 controls the four vibration discs to be started, the clamping pieces 12 are output in a vertical posture that small heads face upwards and notches face backwards under the special design structure of the vibration discs, the widths of the four conveying grooves are not too large, and the clamping pieces 12 are prevented from being greatly deviated in the orientation of the notches in the conveying process. Along with the continuous output clamping piece 12 of vibration dish, clamping piece 12 moves from left to right on defeated material groove, in order to guarantee steady blanking, need control the ejection of compact speed of four vibration dishes, can not be too fast.

The initial position of the receiving tray 10 is that the right side edge is aligned with the discharge ports of the conveying grooves, when the clamping pieces 12 fall down from the discharge ports, the X-direction servo motor (positive rotation) is started to enable the receiving tray 10 to move from left to right, and therefore four clamping pieces 12 fall down on the receiving tray 10 at the same time.

With the continuous rightward movement of the receiving tray 10, four rows of clamping pieces are fully arranged on the receiving tray 10, then the four vibrating trays are controlled to stop, so that the clamping pieces 12 are suspended and fall, then the Y-direction servo motor is controlled to operate, the receiving tray 10 moves from front to back, so that the free area of the receiving tray 10 is aligned with the discharge hole of each material conveying groove, and then the X-direction servo motor is controlled to rotate reversely, so that the receiving tray 10 moves from right to left and returns to the initial position of receiving. And then controlling the four vibrating trays to start, simultaneously enabling the X-direction servo motor to rotate forwards, and enabling the material receiving tray 10 to start moving from left to right to receive materials, and repeating the steps until the clamping pieces are fully placed on the material receiving tray.

The cross sliding table in the embodiment is obliquely arranged, so that the receiving tray 10 is slightly inclined downwards from front to back, and the significance of the arrangement is as follows: because the notches of the clamping pieces 12 face the rear side, in the material receiving process, once the clamping pieces 12 fall down unstably, the clamping pieces topple over uniformly and backwards, the notches of the latter clamping piece are lapped on the outer conical surface of the former clamping piece, and therefore when the material receiving disc is rightly returned, the clamping pieces naturally lean forwards under the action of inertia to be in a vertical state. Conversely, if the clip is tipped forward, it is difficult to tip back to the upright position and it must be manually straightened.

The second embodiment of the automatic clip placement system of the invention: the difference between this embodiment and the first embodiment is that the vibration plate has a local structure, specifically, the structure that a clip with a forward small head passes through and a clip with a forward large head is stopped is different, as shown in fig. 21 and 22, a stopper 416 is disposed on the horizontal clip feeding track downstream of the transition beam 403, the stopper 416 is disposed on one side of the support limiting groove 401, a guide inclined surface 417 is disposed on one side of the stopper 416 facing the support limiting groove 401, the slope of the guide inclined surface 417 matches the taper of the outer conical surface of the clip, and a set distance is provided between the guide inclined surface 417 and the support limiting groove 401, that is, the channel is narrower as going forward.

Thus, when the big head end of the clip is fed forward, the big head end of the clip quickly abuts against the guide inclined surface 417 to generate point contact, and the guide inclined surface 417 has an inclination, so that the guide inclined surface 417 pushes the big head end of the clip forward along with the continuous movement of the clip.

When the small head end of the clip is fed forward, the slope of the guide inclined plane 417 is matched with the taper of the outer conical surface of the clip, so that the clip does not contact the guide inclined plane 417 at the beginning, when the clip moves forward to a certain moment, the outer conical surface of the clip is in line contact with the guide inclined plane 417, as the clip continues to move forward, the guide inclined plane 417 pushes the outer conical surface of the clip, and as the stressed part is dispersed on the outer conical surface of the clip to form a straight line, the whole stress of the clip is relatively uniform, at the moment, under the combined action of vibration and the limit of the support limit groove 401, the clip is not extruded out of the support limit groove 401, but in order to continue to move forward, the posture of the clip is continuously adjusted, the effect of rotating around the axis of the clip is generated, the clip is changed from lying on the side to lying through the stop block, and the clip slowly changes to lying due to the, thus, the clamping piece with the small head end facing forwards is screened out.
