An automatic workpiece placement system and an automatic placement method for taper sleeve clamping pieces

Abstract

The present invention provides an automatic workpiece placement system and an automatic placement method for taper sleeve clamping pieces. The automatic workpiece placement system includes a feeding mechanism and a receiving tray, and further includes an X-direction moving mechanism for driving the receiving tray to reciprocate in the X direction, and a Y-direction moving mechanism for supporting the receiving tray and driving the receiving tray to reciprocate in the Y direction. The X direction and the Y direction form an angle. By controlling the actions of the X-direction and Y-direction moving mechanisms, the receiving tray receives workpieces in one direction. As the relative movement between the receiving tray and the discharge port of the feeding mechanism occurs, the workpieces can be filled in this one direction. Then, through the control of another mechanism, the receiving tray is stepped a certain distance in the other direction, so that the idle area of the receiving tray is aligned with the discharge port of the feeding mechanism, and then the receiving can be continued in the previous direction again. By repeating this cycle until the receiving tray is filled with workpieces. The entire process only requires controlling the reciprocating movement of the receiving tray to fill the workpieces, eliminating the need for manual material placement and greatly reducing the labor intensity.

Description

Technical Field

[0001] The present invention relates to a workpiece automatic placement system and a method for automatically placing taper sleeve clamping pieces. Background Art

[0002] For railways, highways, municipal bridges, river dams and other buildings, in order to reduce their own weight and save steel, prestressed anchorages are required. The taper sleeve clamping piece type anchorage has unique advantages such as good self-anchoring performance, no need for a top press during tensioning, the prestressed steel strands can be stacked in coils, and can be arbitrarily cut according to the required length during on-site use, so it is used more and more widely in various prestressed applications.

[0003] The prestressed taper sleeve clamping piece type anchorage is usually a taper sleeve structure composed of two to three taper sleeve clamping pieces. The structure of the bisected taper sleeve clamping piece in the prior art is as Figure 1 shown. The taper sleeve clamping piece includes a small head end 1201, a large head end 1202, an outer conical surface 1203, an internal thread 1204 and a cross section 1205. As Figure 2 shown, when the taper sleeve clamping piece is "lying flat" and the internal thread is facing up, the length of the taper sleeve clamping piece is L. The internal thread of the taper sleeve clamping piece is processed in a groove, and the groove width is a (when the taper sleeve is bisected, the groove width is the aperture of the internal thread hole). The highest part of the taper sleeve clamping piece is located at the large head end, and the height of the large head end is h. Since two taper sleeve clamping pieces form a taper sleeve, the height h of the large head end = (large head end diameter Φ / 2) - 1.

[0004] During the manufacturing process of the taper sleeve clamping piece, multiple taper sleeve clamping pieces need to be placed on a tray for centralized heat treatment. At present, it depends on manual operation to pick up the taper sleeve clamping pieces one by one and then place them on the tray. Moreover, in order to improve the space utilization rate of the tray and also to ensure the placement stability of the taper sleeve clamping pieces, it is necessary to place the small head end of the taper sleeve clamping piece facing up. At present, this manual placement method has a relatively large labor intensity and a relatively low placement efficiency. Summary of the Invention

[0005] The purpose of the present invention is to provide a workpiece automatic placement system to solve the problem of large labor intensity caused by manual placement of workpieces in the prior art; the purpose of the present invention is also to provide a method for automatically placing taper sleeve clamping pieces that can reduce the manual labor intensity.

[0006] To achieve the above purpose, the following technical solutions are adopted for the workpiece automatic placement system in the present invention:

[0007] A workpiece automatic placement system, comprising:

[0008] A feeding mechanism for conveying workpieces;

[0009] A receiving tray arranged below the discharge port of the feeding mechanism for receiving workpieces;

[0010] A Y-direction moving mechanism for driving the material receiving tray to reciprocate in the Y direction;

[0011] An X-direction moving mechanism is arranged on the Y-direction moving mechanism to support the material receiving tray and drive the material receiving tray to reciprocate in the X direction;

[0012] There is an included angle between the X direction and the Y direction.

[0013] The beneficial effects of the technical solution of the above workpiece automatic placement system are as follows: The feeding mechanism is used to convey workpieces, which can eliminate manual conveying operations and reduce labor intensity; The X-direction moving mechanism and the Y-direction moving mechanism are adopted, and the material receiving tray is supported by the Y-direction moving mechanism. In this way, by controlling the actions of the X-direction moving mechanism and the Y-direction moving mechanism, the material receiving tray can receive workpieces in one direction driven by one of the mechanisms. Since the material receiving tray is arranged below the discharge port of the feeding mechanism, the workpieces will automatically fall into the material receiving tray. With the relative movement between the material receiving tray and the discharge port of the feeding mechanism, the workpieces can be filled in this one direction. Then, the other mechanism controls the material receiving tray to step a certain distance in the other direction, so that the idle area of the material receiving tray is aligned with the discharge port of the feeding mechanism, and the material receiving can be continued in the previous direction again. This cycle continues until the material receiving tray is filled with workpieces. The whole process only needs to control the reciprocating movement of the material receiving tray to fill the material receiving tray with workpieces, without manual material placement, greatly reducing labor intensity.

[0014] Further, in order to make the workpieces fall on the material receiving tray more smoothly, the distance between the discharge port of the feeding mechanism and the material receiving tray is less than the height of the workpieces.

[0015] Further, for the convenience of automatic control and to avoid the placed workpieces being pushed down to achieve smooth material receiving, the workpiece automatic placement system further includes a control device, and the control device is used to control the operation of the vibrating feeding mechanism, the X-direction moving mechanism and the Y-direction moving mechanism, so that the material receiving tray first fills with workpieces in one direction, then steps a certain distance in the other direction, then moves reversely to the initial position in the previous direction and then continues to receive materials.

[0016] Further, in order to improve the placement efficiency, there are at least two feeding mechanisms, and the feeding directions of the feeding mechanisms are arranged in parallel.

[0017] Further, in order to conveniently obtain the required output posture of the workpieces and facilitate the conveying of the workpieces, the feeding mechanism includes a vibrating bowl and a feeding trough connected to the discharge port of the vibrating bowl, and the end of the feeding trough far from the discharge port of the vibrating bowl is arranged to incline downward.

[0018] Further, to facilitate the configuration of the X-direction moving mechanism and the Y-direction moving mechanism and the placement of the receiving tray, the X-direction and the Y-direction are perpendicular to each other. The X-direction moving mechanism and the Y-direction moving mechanism form a cross slide, the receiving tray is a square or rectangular receiving tray, and the feeding direction of the feeding mechanism is perpendicular to the extending direction of one of the sides of the receiving tray.

[0019] To achieve the above object, the following technical solution is adopted for the automatic placement method of the taper sleeve clamping pieces in the present invention:

[0020] An automatic placement method for taper sleeve clamping pieces uses a Y-direction moving mechanism and an X-direction moving mechanism provided on the Y-direction moving mechanism for supporting the receiving tray, controls the receiving tray to move in one of the X-direction and the Y-direction to fill the taper sleeve clamping pieces falling from the discharge port of the feeding mechanism in this direction, and then controls the receiving tray to step a certain distance in the other direction, and then continues to receive materials in the previous direction. This cycle continues until the receiving tray is full of taper sleeve clamping pieces.

[0021] The beneficial effect of the technical solution of the above automatic placement method for taper sleeve clamping pieces is that by controlling the actions of the X-direction moving mechanism and the Y-direction moving mechanism, the receiving tray can be driven by one of the mechanisms to receive taper sleeve clamping pieces in one direction. As the relative movement between the receiving tray and the discharge port of the feeding mechanism, the taper sleeve clamping pieces automatically fall into the receiving tray and are filled in this direction. Then, the other mechanism controls the receiving tray to step a certain distance in the other direction to align the idle area of the receiving tray with the discharge port of the feeding mechanism, and then the receiving tray can continue to receive materials in the previous direction. This cycle continues until the receiving tray is full of taper sleeve clamping pieces. The whole process only controls the reciprocating movement of the receiving tray, so that the receiving tray can be filled with taper sleeve clamping pieces without manual placement, greatly reducing the labor intensity.

[0022] Further, to enable as many taper sleeve clamping pieces as possible to be placed on the receiving tray and improve the utilization rate of the receiving tray, the taper sleeve clamping pieces output by the feeding mechanism are in an upright posture with the small head facing up through a vibrating disk.

[0023] Further, to facilitate the righting of the workpiece once it is tilted, when each taper sleeve clamping piece falls from the discharge port of the feeding mechanism onto the receiving tray, the notches face in the same direction. It is defined that when the taper sleeve clamping piece falls from the discharge port of the feeding mechanism onto the receiving tray, the notch faces backward, and the receiving tray is gradually inclined downward from front to back.

[0024] Further, to enable the workpiece to fall on the receiving tray more smoothly, the distance between the discharge port of the feeding mechanism and the receiving tray is less than the height of the workpiece. The moving sequence of the receiving tray includes: first filling the workpiece in one direction, then stepping a certain distance in the other direction, and then moving backward to the initial position in the previous direction and continuing to receive materials.

[0048] In the first embodiment of the workpiece automatic placement system of the present invention, as Figures 3 to 5 shown, the workpiece in this embodiment is a bisected cone sleeve clip 12. The workpiece automatic placement system includes a feeding mechanism for conveying the cone sleeve clip. As Figure 4 shown, there are four feeding mechanisms in total, namely the first feeding mechanism composed of the first vibrating bowl 1 and the first feeding trough 5, the second feeding mechanism composed of the second vibrating bowl 2 and the second feeding trough 6, the third feeding mechanism composed of the third vibrating bowl 3 and the third feeding trough 7, and the fourth feeding mechanism composed of the fourth vibrating bowl 4 and the fourth feeding trough 8.

[0049] The first and third vibrating plates 1 and 3 are arranged front to back, and the second and fourth vibrating plates 2 and 4 are also arranged front to back, and the first and third vibrating plates 1 and 3 are respectively located on the left side of the second and fourth vibrating plates 2 and 4. Each feed trough is connected to the discharge port of the corresponding vibrating plate. The four feed troughs are arranged in parallel, with adjacent feed troughs tightly attached to each other, and each feed trough gradually tilts downward from left to right. In this way, as the vibrating plate continuously vibrates out the cone sleeve clip 12, each cone sleeve clip 12 automatically moves to the right under the action of the inclined surface.

[0050] The automatic workpiece placement system also includes a cross slide 11 arranged downstream of the four feeding troughs, and a receiving tray 10 for receiving and placing the taper sleeve clips is placed on the top of the cross slide 11. Figure 7 and Figure 8 As shown, the cross slide 11 includes a Y-direction moving mechanism 1101 and an X-direction moving mechanism 1109 arranged above the Y-direction moving mechanism 1101, wherein the X-direction is the left-right direction, the Y-direction is the front-back direction, and the X-direction and the Y-direction are perpendicular to each other.

[0051] Y-axis movement mechanism 1101 includes a frame-like base 1106, on which are mounted a Y-axis guide rod 1102 and a Y-axis motor mounting bracket 1104. The four uprights of base 1106 are of varying heights, causing Y-axis guide rod 1102 to gradually tilt downward from front to back. Y-axis motor mounting bracket 1104 is mounted a Y-axis motor 1105 and a Y-axis lead screw 1103, which is in transmission connection with Y-axis motor 1105. A Y-axis platform bracket 1107 is mounted on Y-axis lead screw 1103 and Y-axis guide rod 1102, with a Y-axis platform 1108 fixed to the top of Y-axis platform bracket 1107. The Y-axis platform bracket 1107 is in sliding cooperation with the Y-axis guide rod 1102 and is threadedly connected with the Y-axis lead screw 1103. Therefore, when the Y-axis motor 1105 drives the Y-axis lead screw 1103 to rotate, under the action of the lead screw nut principle, the Y-axis platform bracket 1107 slides back and forth along the Y-axis guide rod 1102, and then drives the Y-axis platform 1108 to move back and forth.

[0052] The X-direction moving mechanism 1109 includes an X-direction motor mounting bracket 1111 and an X-direction guide rod 1114 disposed on the Y-direction platform 1108. An X-direction motor 1115 and an X-direction lead screw 1113 drivingly connected to the X-direction motor 1115 are mounted on the X-direction motor mounting bracket 1111. An X-direction platform bracket 1112 is mounted on the X-direction guide rod 1114 and the X-direction lead screw 1113. The top of the X-direction platform bracket 1112 is fixed with an X-direction platform 1110. The X-direction platform bracket 1112 is in guiding and sliding fit with the X-direction guide rod 1114 and in threaded connection with the X-direction lead screw 1113. Therefore, when the X-direction motor 1115 drives the X-direction lead screw 1113 to rotate, under the action of the lead screw-nut principle, the X-direction platform bracket 1112 slides left and right along the X-direction guide rod 1114, thereby driving the X-direction platform 1110 to move left and right.

[0053] The material receiving tray 10 is placed on the X-direction platform 1110. When the X-direction motor 1115 and the Y-direction motor 1105 operate respectively, the material receiving tray 10 can move to receive materials in the left-right and front-back directions respectively. The material receiving tray 10 is square, and the feeding directions of the four feeding grooves are all in the left-right direction, that is, the extending directions of the four feeding grooves are all perpendicular to the extending direction of the left side of the material receiving tray 10. The material receiving tray 10 is always located below the discharge ports of the respective feeding grooves during the material receiving process. And preferably, in order to ensure smooth material dropping, the material receiving tray 10 is in contact with the discharge ports of the respective feeding grooves, and on the premise that the taper sleeve clamping pieces can meet the conveying requirements, the inclination angles of the respective feeding grooves are made as small as possible.

[0054] The workpiece automatic placement system further includes a control device 9 for controlling the operation of the first vibrating bowl 1, the second vibrating bowl 2, the third vibrating bowl 3, the fourth vibrating bowl 4, the X-direction servo motor, and the Y-direction servo motor, as Figure 6 shown. The control device 9 includes an operation panel 91. A controller (not shown in the figure) is provided inside the control device 9. In addition, cameras are installed near each vibrating bowl, near each feeding groove, and near the cross slide for collecting real-time video information of the conveying of the taper sleeve clamping pieces and transmitting it to the control device 9. Then, according to the real-time operation information, the control device 9 controls the start-stop and rotation directions of the above-mentioned respective components, that is, visual management is adopted.

[0055] In the workpiece automatic placement system of the present invention, through the structural design of the vibrating bowls, the taper sleeve clamping pieces 12 finally output by each vibrating bowl are all in an upright posture with the small head facing up and the concave notch facing backward. Taking the fourth vibrating bowl 4 as an example, a spiral vibrating feeding track is provided on the fourth vibrating bowl 4. The vibrating feeding track is used to support the taper sleeve clamping pieces 12 and drive the taper sleeve clamping pieces to move forward and spiral upward under the action of vibration.

[0056] As Figure 9As shown in the figure, it is a partial structural diagram of the fourth vibrating disk 4. The vibrating feeding track includes a horizontal tapered sleeve clip feeding track and a vertical tapered sleeve clip feeding track. The horizontal tapered sleeve clip feeding track includes a support wall 407 and a side wall 404. In order to form a good supporting and limiting effect on the tapered sleeve clip, a continuous supporting and limiting structure is provided on the support wall 407. The supporting and limiting structure is specifically a supporting and limiting groove 401 opened on the support wall 407. The supporting and limiting groove 401 is V-shaped, which can support and limit the outer conical surface of the tapered sleeve clip, ensure that the tapered sleeve clip can be smoothly conveyed forward, and make it not easy for the tapered sleeve clip to be shaken off. The tapered sleeve clip not supported by the supporting and limiting groove 401 is easy to be shaken off the track and fall back into the vibrating disk again. And the extending direction of the supporting and limiting groove 401 is the same as that of the support wall 407, so the large-end or small-end of the tapered sleeve clip can move forward.

[0057] Along the moving direction of the tapered sleeve clip 12, a blocking plate 402, a transition beam 403, a fixed baffle 405, a moving baffle 409 and a groove 406 are sequentially arranged on the horizontal tapered sleeve clip feeding track. Among them, one end of the blocking plate 402 is fixed on the side wall 404 and the other end extends. The blocking plate 402 is horizontally arranged, and the distance from the blocking plate 402 to the support wall 407 is less than the length L of the tapered sleeve clip. Therefore, the vertical tapered sleeve clip cannot pass through the blocking plate 402 and can only be blocked by the blocking plate 402 and fall into the vibrating disk, as Figure 18 shown. Or it is blocked and falls into a horizontal posture. The horizontal tapered sleeve clip can pass through the blocking plate 402 and continue to be conveyed forward. In this way, the vertical tapered sleeve clip is removed, or in other words, the horizontal tapered sleeve clip is screened out.

[0058] The transition beam 403 is arranged downstream of the blocking plate 402. The transition beam 403 is a part of the support wall 407, and its width is less than the groove width a of the tapered sleeve clip groove. It is equivalent to a relatively narrow support wall, and the length of the transition beam 403 is greater than the length L of the tapered sleeve clip. In this way, when the tapered sleeve clip with the internal thread facing up passes through the transition beam 403, under the action of the supporting and limiting groove 401, it can be supported and continue to be conveyed, as Figure 9 shown. When the tapered sleeve clip with the internal thread facing down passes through the transition beam 403, at first it "rides" on the transition beam 403, but it is very easy to rotate around the transition beam 403 and slide off under the vibration, as Figure 18 shown. Even if there are individual tapered sleeve clips that can stably "ride" on the transition beam 403, when they continue to move forward, they will touch the end face (i.e., the stop surface 408) of the next section of the support wall and fall off. In this way, the tapered sleeve clips with the internal thread facing up are screened out.

[0059] One end of the fixed baffle 405 is fixed on the side wall 404 and the other end extends. The movable baffle 409 is installed on the fixed baffle 405 in a guiding manner in the up and down direction, and the fixed baffle 405 is provided with a guiding hole for the up and down guiding movement of the movable baffle 409. As Figure 19 shown is a matching form of the fixed baffle and the movable baffle. The guiding hole on the fixed baffle 405 is a blind hole with the orifice facing downwards. A spring 415 is arranged between the bottom of the guiding hole and the movable baffle 409. One end of the spring 415 is fixed on the bottom of the guiding hole and the other end is fixed on the movable baffle 409. The movable baffle 409 is equivalent to being hoisted on the fixed baffle 405 through the spring 415. When an upward acting force is applied to the movable baffle 409, the spring 415 can be compressed and the movable baffle 409 moves upwards.

[0060] The movable baffle 409 includes a material receiving surface 4091 which is inclined in the direction of the incoming material. And before the incoming material, the distance between the bottom end of the material receiving surface 4091 and the support wall 407 is less than the height h of the large end of the taper sleeve clip. In this way, when the taper sleeve clip with the large end facing forward comes, due to the relatively high large end, it will contact the inclined material receiving surface 4091 and then be guided to slide off the feeding track under the vibration. At the same time, the distance between the bottom end of the material receiving surface 4091 and the support wall 407 is greater than the height of the small end of the taper sleeve clip. In this way, when the taper sleeve clip with the small end facing forward comes, due to the relatively low small end, it can drill under the movable baffle 409. And because the cross section of the taper sleeve clip is in an inclined state when the taper sleeve clip lies flat, so as the taper sleeve clip continues to move forward, the cross section 1205 of the taper sleeve clip will apply an upward acting force to the movable baffle 409, forcing the movable baffle 409 to compress the spring 415 and move upwards. Finally, the taper sleeve clip can pass through the movable baffle 409, and then the movable baffle 409 resets under the reaction force of the spring.

[0061] In addition, the side surface of the fixed baffle 405 facing the incoming material direction is an inclined surface 4051. The inclined surface 4051 is arranged parallel to the material receiving surface 4091, and there is a set distance between the fixed baffle 405 and the support wall 407. In this way, a part of the taper sleeve clips with the large end facing forward and the two cross sections 1205 not at the same height, that is, the taper sleeve clips with the two cross sections 1205 at different heights and the overall higher large end, will directly contact the inclined surface 4051 and be guided to fall by the inclined surface 4051 without being guided to fall by the movable baffle 409.

[0062] The setting of the inclined surface 4051 is equivalent to sharing part of the responsibility of the movable baffle 409. In this way, the height of the fixed baffle 405 is not too high, which in turn means that the length of the movable baffle 409 is not too long. Otherwise, if only the movable baffle 409 is used to block the tapered sleeve clamping piece, the fixed baffle 405 needs to be set higher, and then the movable baffle 409 needs to be set longer. This will cause the weight of the movable baffle 409 to increase, which is not conducive to its upward movement, and even the situation where the tapered sleeve clamping piece cannot lift it up may occur.

[0063] As Figure 20 shown is another matching form of the fixed baffle and the movable baffle. The cross-section of the movable baffle 409' is T-shaped, and the guiding hole on the fixed baffle 405' is a through hole. The movable baffle 409' is directly in guiding sliding fit with the fixed baffle 405'. At this time, the movable baffle 409' falls by its own weight after being lifted by the tapered sleeve clamping piece. And similarly, a material receiving surface 4091' is provided on the movable baffle 409', and an inclined surface 4051' is provided on the fixed baffle 405'. The principle is the same as above and will not be repeated here. In this way, the tapered sleeve clamping pieces passing through the fixed baffle and the movable baffle are all in the posture with the internal thread facing up and the small head end facing forward.

[0064] Taking the vibrating disk itself as the reference object, if the tapered sleeve clamping piece moves forward, the vertical tapered sleeve clamping piece feeding track is arranged on the right side of the horizontal tapered sleeve clamping piece feeding track and is parallel to it. As Figure 10 and Figure 17 shown, the vertical tapered sleeve clamping piece feeding track includes a supporting surface 413 for supporting the end face of the large head end of the tapered sleeve clamping piece, and two limiting side walls perpendicular to the supporting surface 413 for preventing the vertical tapered sleeve clamping piece from rotating. The two limiting side walls are the inner limiting side wall 412 and the outer limiting side wall 411 respectively. The distance between the inner limiting side wall 412 and the outer limiting side wall 411 matches the height of the large head end of the tapered sleeve clamping piece.

[0065] The groove 406 is arranged at the end of the horizontal tapered sleeve clamping piece feeding track. As Figure 11 shown, the groove 406 includes a bottom supporting wall 4061 for supporting the large head end of the tapered sleeve clamping piece and a side supporting wall 4062 for supporting the outer conical surface of the tapered sleeve clamping piece. The length of the groove 406 is less than the length L of the tapered sleeve clamping piece 12, and supporting limiting grooves 401 are arranged on both the front and rear sides of the groove 406. Therefore, as Figure 12 shown, when the tapered sleeve clamping piece with the small head end facing forward moves to the position of the groove 406, due to the center of gravity of the tapered sleeve clamping piece being behind, the small head end of the tapered sleeve clamping piece can cross over the groove 406. At a certain moment, the tapered sleeve clamping piece straddles the groove, and its large head end and small head end are both supported on the supporting limiting grooves 401.

[0066] As Figure 13As shown, as the drogue clip continues to move forward, its larger end overhangs the groove. Due to its unstable center of gravity, the larger end falls into the groove, becoming tilted. At this point, the larger end of the drogue clip is supported by the bottom support wall 4061, while the outer conical surface of the drogue clip is supported by the side support walls 4062. The groove 406 also includes a stop wall 4063 opposite the side support wall 4062, which stops the larger end of the drogue clip.

[0067] The bottom support wall 4061 gradually tilts from top to bottom toward the support surface 413 and contacts the support surface 413, so that under the action of its own weight, the cone sleeve clip falling into the groove will slide down along the bottom support wall 4061. Figure 11 As shown, a transition guide wall 414 is provided between the inner limiting side wall 412 and the side support wall 4062. The transition guide wall 414 is an arc-shaped wall that can guide the tapered sleeve clip to transition to the support surface 413 when it slides downward. Figure 14 As shown, this is equivalent to guiding the cone sleeve clip to turn.

[0068] There is also an arcuate transition between the outer limiting side wall 411 and the stop wall 4063, which helps the cone sleeve clip to transition to the support surface 413. In order to prevent the cone sleeve clip from escaping from the vertical cone sleeve clip feeding track during the transition to the support surface 413, an upward folded upper edge 410 is provided at the top of the outer limiting side wall 411 opposite to the transition guide wall 414. The upper edge 410 extends toward the groove and is arc-shaped. The upper edge 410 cooperates with the transition guide wall 414 to prevent the cone sleeve clip from escaping from the vertical cone sleeve clip feeding track during the turning process. Figure 14 and Figure 15 shown.

[0069] As the cone sleeve clip continues to move, since the distance between the inner limiting side wall 412 and the outer limiting side wall 411 matches the height of the cone sleeve clip's large end, the cone sleeve clip gradually becomes a vertical posture on the support surface 413, and the orientation of the notches is consistent, such as Figure 16 and Figure 17 It should be noted that, through the reasonable design of the vibration plate structure, the notches of the cone sleeve clips output by the four vibration plates can all face Figure 4 At the rear of the vibrating disk, the structural principles used to prevent the vertical cone sleeve clamp from passing through, the internal thread downward cone sleeve clamp from passing through, the large head end forward cone sleeve clamp from passing through, and the conversion from horizontal to vertical are all the same.

[0070] The working principle of the automatic workpiece placement system of the present invention, that is, the automatic placement method of the tapered sleeve clips of the present invention is:

[0071] During use, the control device 9 controls the start of the four vibrating bowls. The tapered sleeve clamping pieces 12 are output in a vertical posture with the small head facing up and the notch facing backward under the special design structure of the vibrating bowls. The groove widths of the four feeding grooves are not too large to prevent large deviations in the orientation of the notch of the tapered sleeve clamping pieces 12 during transportation. As the vibrating bowls continuously output the tapered sleeve clamping pieces 12, the tapered sleeve clamping pieces 12 move from left to right on the feeding grooves. To ensure smooth blanking, it is necessary to control the discharging speed of the four vibrating bowls and not make it too fast.

[0072] The initial orientation of the receiving tray 10 for receiving materials is that the right side is aligned with the discharge ports of the respective feeding grooves. When the tapered sleeve clamping pieces 12 are about to fall from the discharge ports, the X-axis servo motor (rotating forward) is started to make the receiving tray 10 also move from left to right, so that four tapered sleeve clamping pieces 12 will fall onto the receiving tray 10 at the same time.

[0073] As the receiving tray 10 continuously moves to the right, four rows of tapered sleeve clamping pieces will be filled on the receiving tray 10. Then, the four vibrating bowls are controlled to stop, so that the falling of the tapered sleeve clamping pieces 12 is paused. Next, the Y-axis servo motor is controlled to operate, making the receiving tray 10 move from front to back, so that the idle area of the receiving tray 10 is aligned with the discharge ports of the respective feeding grooves. Then, the X-axis servo motor is controlled to rotate in reverse, making the receiving tray 10 move from right to left and return to the initial orientation for receiving materials. Then, the four vibrating bowls are controlled to start, and at the same time, the X-axis servo motor is rotated forward, and the receiving tray 10 starts to move from left to right again for receiving materials. This cycle continues until the receiving tray is filled with tapered sleeve clamping pieces.

[0074] In this embodiment, the cross slide is inclined, making the receiving tray 10 slightly inclined downward from front to back. The significance of this setting is that since the notches of the respective tapered sleeve clamping pieces 12 all face backward, during the material receiving process, once the falling of the tapered sleeve clamping pieces 12 is unstable and they topple over, they will all topple backward uniformly. The notch of the latter tapered sleeve clamping piece rests on the outer tapered surface of the previous tapered sleeve clamping piece. In this way, when the receiving tray is returned to the upright position, under the action of inertia, the tapered sleeve clamping pieces will naturally tilt forward and become vertical. On the contrary, if the tapered sleeve clamping pieces tilt forward, it is very difficult to return to the vertical state and manual straightening is required.

[0075] Embodiment 2 of the workpiece automatic placement system in the present invention: The difference between this embodiment and Embodiment 1 lies in the local structure of the vibrating bowl, specifically, the structure for allowing the tapered sleeve clamping pieces with the small head end facing forward to pass through and blocking the falling of the tapered sleeve clamping pieces with the large head end facing forward is different, as Figure 21 and Figure 22As shown, a stop block 416 is provided downstream of the transition beam 403 on the horizontal tapered sleeve clamping piece feeding track. The stop block 416 is arranged on one side of the support limiting groove 401. A guiding inclined surface 417 is provided on the side of the stop block 416 facing the support limiting groove 401. The slope of the guiding inclined surface 417 matches the taper of the outer conical surface of the tapered sleeve clamping piece, and there is a set distance between the guiding inclined surface 417 and the support limiting groove 401, that is, the channel becomes narrower towards the front.

[0076] In this way, when the tapered sleeve clamping piece with the large head end facing forward comes in, the large head end quickly touches the guiding inclined surface 417 to produce a point contact. Due to the slope of the guiding inclined surface 417, as the tapered sleeve clamping piece continues to move forward, the guiding inclined surface 417 exerts a pushing effect on the large head end of the tapered sleeve clamping piece. Since the force application point is concentrated on the large head end, the overall force on the tapered sleeve clamping piece is uneven, and it will soon break away from the support limiting groove 401 and deflect until it slides off the vibrating feeding track.

[0077] When the tapered sleeve clamping piece with the small head end facing forward comes in, since the slope of the guiding inclined surface 417 matches the taper of the outer conical surface of the tapered sleeve clamping piece, the tapered sleeve clamping piece does not contact the guiding inclined surface 417 at the beginning. When the tapered sleeve clamping piece moves forward to a certain moment, a line contact is generated between the outer conical surface of the tapered sleeve clamping piece and the guiding inclined surface 417. As the tapered sleeve clamping piece continues to move forward, the guiding inclined surface 417 exerts a pushing effect on the outer conical surface of the tapered sleeve clamping piece. Since the force application parts are dispersed in a straight line on the outer conical surface of the tapered sleeve clamping piece, the overall force on the tapered sleeve clamping piece is relatively uniform. At this time, under the combined action of vibration and the limitation of the support limiting groove 401, the tapered sleeve clamping piece will not be pushed out of the support limiting groove 401. Instead, in order to continue moving forward, it continuously adjusts its own posture, producing an effect of rotating around its own axis, changing from lying flat to lying on its side and passing through the stop block. After passing through, due to the action of gravity and vibration, the tapered sleeve clamping piece slowly becomes lying flat again, so that the tapered sleeve clamping piece with the small head end facing forward is screened out.

[0078] In other embodiments of the workpiece automatic placement system, the workpiece automatically placed by the workpiece automatic placement system can also be a tapered sleeve clamping piece divided into three equal parts.

[0079] In other embodiments of the workpiece automatic placement system, the workpiece may not be a tapered sleeve clamping piece, but other workpieces that need to be neatly placed on the receiving tray.

[0080] In other embodiments of the workpiece automatic placement system, the notches of the tapered sleeve clamping pieces can also all face forward. This posture of the notch facing forward or backward is related to the conveying direction of the tapered sleeve clamping piece being in the left-right direction, which can make the tapered sleeve clamping piece fall more stably on the receiving tray and reduce the possibility of tipping over.

[0081] In other embodiments of the automatic workpiece placement system, the heights of the four columns of the Y-direction moving mechanism in the cross slide table can also be equal. At this time, the Y-direction platform is horizontal, so the receiving tray is also horizontally arranged.

[0082] In other embodiments of the automatic workpiece placement system, as long as the workpiece can stably land on the receiving tray, the distance between the discharge port of the feeding mechanism and the receiving tray can also be greater than the height of the workpiece.

[0083] In other embodiments of the automatic workpiece placement system, when the distance between the discharge port of the feeding chute and the receiving tray is greater than the height of the workpiece and does not affect the stable falling of the workpiece, the moving sequence of the receiving tray can be to first move from left to right to receive materials. After being full in the left-right direction, it moves from front to back, aligning the idle area of the receiving tray with the discharge port, and then directly moves from right to left to receive materials without returning to the initial receiving position. The entire route is a serpentine route.

[0084] In other embodiments of the automatic workpiece placement system, the placement orientation of the cross slide table can be adjusted so that the moving direction of the X-direction moving mechanism is the front-back direction. At this time, the moving direction of the Y-direction moving mechanism is the left-right direction. At this time, the Y-direction moving mechanism drives the receiving tray and the X-direction moving mechanism to move left and right as a whole. The X-direction moving mechanism can only control the receiving tray to move in the front-back direction. At this time, the receiving sequence is as follows: the receiving tray and the X-direction moving mechanism move from left to right to receive materials under the control of the Y-direction moving mechanism. After being full in the left-right direction, the X-direction moving mechanism alone controls the receiving tray to move from front to back, aligning the idle area of the receiving tray with the discharge port of the feeding chute. Then, the Y-direction moving mechanism controls the receiving tray and the X-direction moving mechanism to move from right to left to return to the initial receiving position, and then makes the receiving tray and the X-direction moving mechanism move from left to right to receive materials again. This cycle continues until the receiving tray is full of taper sleeve clips. Of course, in other embodiments, the moving route of the receiving tray is the serpentine route described in the previous embodiment.

[0085] In other embodiments of the automatic workpiece placement system, the receiving tray can also be a rectangular receiving tray.

[0086] In other embodiments of the automatic workpiece placement system, the X-direction and the Y-direction may not be perpendicular. For example, their included angle can be 60 degrees. At this time, the X-direction moving mechanism and the Y-direction moving mechanism are more suitable for a diamond-shaped receiving tray.

[0087] In other embodiments of the automatic workpiece placement system, the automatic workpiece placement system may not include a control device. At this time, an operator can work beside the machine and control the opening and closing of the machine by manually controlling the switch of the machine. Since the worker only needs to operate the switch button, the labor intensity is still greatly reduced compared to manually placing workpieces.

[0088] In other embodiments of the workpiece automatic placement system, the feeding chute may not be inclined but horizontal. In this case, a linear vibrating feeding chute can be used to move the workpiece to the right under the action of vibration.

[0089] In other embodiments of the workpiece automatic placement system, the tapered sleeve clamping piece output by the vibrating bowl can also be in a horizontal posture instead of a vertical one. The tapered sleeve clamping piece can be placed flat on the receiving tray. At this time, there may be no vertical tapered sleeve clamping piece feeding track on the vibrating bowl, and only a horizontal tapered sleeve clamping piece feeding track is needed.

[0090] In other embodiments of the workpiece automatic placement system, when there are no special requirements for the output posture of the workpiece, the feeding mechanism may not include a vibrating bowl, but only an ordinary belt conveyor or vibrating conveyor. At this time, the feeding mechanism is only responsible for automatically conveying the workpiece. Since the receiving tray can automatically receive the workpiece under the control of the X-direction moving mechanism and the Y-direction moving mechanism, the labor intensity can still be reduced.

[0091] In other embodiments of the workpiece automatic placement system, there may be two, three, five or more feeding mechanisms. Of course, there may also be only one feeding mechanism. When there is only one feeding mechanism, the feeding direction does not need to extend perpendicular to the side extension direction of the receiving tray, and the feeding direction can be any direction.

[0092] An embodiment of the method for automatically placing the tapered sleeve clamping piece in the present invention is as follows: The method for automatically placing the tapered sleeve clamping piece is the same as the method for automatically placing the tapered sleeve clamping piece included in the above embodiment, and will not be repeated here.
