Description

Technical Field

[0001] The invention relates to an elastic ring feeding device and an elastic ring fitting system. Background Art

[0002] In current assembly line operations, materials are often loaded through a loading device so that the materials are neatly arranged and arrive at the assembly position, which is convenient for subsequent processes. Taking the anchor ring assembly process commonly used in the construction field as an example, the clips need to be matched to form a cone tube first, and then the elastic ring is inserted into the slot at the large diameter end of the cone tube, and the cone tube is tightened with the elastic ring. In the automated production process, the elastic ring needs to be transported to the assembly position in an orderly manner through an elastic ring loading device, and the shape of the elastic ring needs to be kept good so that the elastic ring can be smoothly assembled into the slot.

[0003] A Chinese utility model patent with the authorization announcement number CN208499517U discloses a sorting conveyor for deformable rubber ring parts, which conveys the rubber ring to the spiral material channel through a disc-shaped vibrating feeder. The disc-shaped vibrating feeder is a vibrating plate for vibrating the workpiece, and the workpiece enters the support plate of the conveying mechanism from the spiral material channel. The conveying mechanism is a step-by-step conveying mechanism, and multiple limit columns are equidistantly arranged on the pull plate, and the rubber ring is driven to move by the limit columns. The sorting conveyor can realize the orderly placement and conveying of rubber rings.

[0004] In the above-mentioned flexible rubber ring parts sorting conveyor, it is necessary to set a transmission cylinder to drive the limit column to move, and to set a longitudinal cylinder to realize the combination and separation of the limit column and the elastic ring. Each time the elastic ring moves forward to a standard position, the transmission cylinder and the longitudinal cylinder need to act twice each. The entire conveying mechanism has a complex structure and a relatively low conveying efficiency, which reduces the assembly efficiency of the entire elastic ring set system. Summary of the invention

[0005] The purpose of the present invention is to provide an elastic ring feeding device to solve the problem of complex structure of the elastic ring conveying mechanism in the prior art. At the same time, the present invention also provides an elastic ring assembly system to solve the problem of low assembly efficiency of the elastic ring assembly system caused by low conveying efficiency of the elastic ring conveying mechanism.

[0006] To achieve the above-mentioned purpose, the technical scheme of the elastic ring feeding device of the present invention is that the elastic ring feeding device comprises: an elastic ring vibrating plate for vibrating the elastic rings and arranging the elastic rings in an orderly manner; and further comprises:

[0007] The guide plate is arranged at the discharge port of the elastic ring vibration conveying plate and is arranged to be inclined downward from the discharge port to guide the elastic ring to move downward;

[0008] An elastic ring conveyor belt is arranged below the lower end of the guide plate to receive the elastic ring sent out by the elastic ring vibrating plate. A plurality of stoppers are arranged on the belt surface of the elastic ring conveyor belt to drive the elastic ring to move. The stoppers are push blocks arranged on the belt surface of the conveyor belt. The push blocks have an arc-shaped edge for matching with the inner edge of the elastic ring and driving the elastic ring to move. The distance between the arc edges of two adjacent push blocks is equal to the diameter size of the outer edge of the elastic ring.

[0009] The elastic ring feeding device of the present invention has the following beneficial effects: the elastic ring sent out through the elastic ring vibrating feeding plate falls on the elastic ring conveyor belt through the guide plate, moves toward the assembly position under the action of the stopper on the elastic ring conveyor belt, and drives the elastic ring to move through the stopper, which can meet the long-distance transportation of the elastic ring and realize the automatic feeding of the elastic ring. During the whole conveying process, the elastic ring is driven to move through the rotation of the elastic ring conveyor belt. Compared with the prior art that requires two cylinders to realize the step-by-step movement of the elastic ring, the structure is simpler and the conveying efficiency is also improved. During the conveying process, due to the action of the stopper, the elastic rings will not be squeezed and deformed by each other, so that the shape of the elastic ring is kept good, which is convenient for subsequent assembly. The push block has a simple structure and is easy to be fixed on the belt surface of the elastic ring conveyor belt. The arc edge of the push block forms a stopper with the inner edge of the elastic ring, which can drive the elastic ring to move and keep the elastic ring in good shape.

[0010] Furthermore, the end of the guide plate is provided with a semicircular end head extending perpendicular to the plate surface direction of the guide plate, the semicircular end head is used to position the elastic ring, the end of the guide plate is provided with a semicircular hole, the hole wall of the semicircular hole is provided with a semicircular support guide piece, the center of the circle corresponding to the semicircular hole is concentric with the center of the circle corresponding to the semicircular support piece, the semicircular support guide piece is inclined from top to bottom in the conveying direction of the elastic ring conveyor belt, the arc edge of the semicircular support guide piece and the arc wall of the semicircular hole form a rubber ring sliding-out gap for the elastic ring to slide out of the guide plate.

[0011] Beneficial effect: a semicircular end head is arranged to position the elastic ring so that the elastic ring is just above the semicircular support guide piece. When the elastic ring moves to the semicircular support guide piece, it slides downward under the action of gravity, and slides from the sliding gap between the semicircular support guide piece and the guide plate to the elastic ring conveyor belt, and is taken away by the stopper on the elastic ring conveyor belt. Such an arrangement ensures that each stopper can take away one elastic ring, thereby improving assembly efficiency.

[0012] The technical solution of the elastic ring set system of the present invention is that the elastic ring set system comprises:

[0013] The elastic ring fitting device is used to fit the elastic ring into the groove in the cone tube.

[0014] A clip feeding device is used to convey the clips to the elastic ring fitting device and form a cone tube;

[0015] The elastic ring set system also includes,

[0016] An elastic ring feeding device comprises an elastic ring vibrating and feeding disk, a guide plate and an elastic ring conveyor belt. The elastic ring vibrating and feeding disk is used to vibrate the elastic rings and arrange the elastic rings in an orderly manner. The guide plate is arranged at the discharge port of the elastic ring vibrating and feeding disk and is arranged to tilt downward from the discharge port to guide the elastic rings to move downward. The elastic ring conveyor belt is arranged below the lower end of the guide plate to receive the elastic rings delivered by the elastic ring vibrating and feeding disk. A plurality of stoppers are arranged on the belt surface of the elastic ring conveyor belt to drive the elastic rings to move. The stoppers are push blocks arranged on the belt surface of the conveyor belt. The push blocks have an arc-shaped edge for matching with the inner edge of the elastic ring and driving the elastic ring to move. The distance between the arc edges of two adjacent push blocks is equal to the diameter size of the outer edge of the elastic ring.

[0017] The elastic ring assembly system of the present invention has the following beneficial effects: the elastic ring delivered by the elastic ring vibration and delivery disk falls onto the elastic ring conveyor belt through the guide plate, and moves toward the assembly position under the action of the stopper on the elastic ring conveyor belt, and the elastic ring is driven to move by the stopper, which can meet the long-distance transportation of the elastic ring and realize the automatic loading of the elastic ring. During the whole conveying process, the movement of the elastic ring is driven by the rotation of the elastic ring conveyor belt. Compared with the prior art that needs to set two cylinders to realize the step-by-step movement of the elastic ring, the structure is simpler and the conveying efficiency is also improved. During the conveying process, due to the action of the stopper, the elastic rings will not be squeezed and deformed by each other, the pushing block has a simple structure and is easy to be fixed on the belt surface of the elastic ring conveyor belt, the arc-shaped edge of the pushing block forms a stopper with the inner edge of the elastic ring, which can drive the elastic ring to move, so that the shape of the elastic ring is kept good, and the clip is transported to the position corresponding to the elastic ring in the elastic ring assembly device through the clip feeding device, and is automatically assembled in the elastic ring assembly device, thereby improving the assembly efficiency.

[0018] Furthermore, the end of the guide plate is provided with a semicircular end head extending perpendicular to the plate surface direction of the guide plate, the semicircular end head is used to position the elastic ring, the end of the guide plate is provided with a semicircular hole, the hole wall of the semicircular hole is provided with a semicircular support guide piece, the center of the circle corresponding to the semicircular hole is concentric with the center of the circle corresponding to the semicircular support piece, the semicircular support guide piece is inclined from top to bottom in the conveying direction of the elastic ring conveyor belt, the arc edge of the semicircular support guide piece and the arc wall of the semicircular hole form a rubber ring sliding-out gap for the elastic ring to slide out of the guide plate.

[0019] Beneficial effect: a semicircular end head is arranged to position the elastic ring so that the elastic ring is just above the semicircular support guide piece. When the elastic ring moves to the semicircular support guide piece, it slides downward under the action of gravity, and slides from the sliding gap between the semicircular support guide piece and the guide plate to the elastic ring conveyor belt, and is taken away by the stopper on the elastic ring conveyor belt. Such an arrangement ensures that each stopper can take away one elastic ring, thereby improving assembly efficiency.

[0020] Furthermore, the elastic ring set device comprises:

[0021] Support frame: The support frame has a cone tube placement space for placing the cone tube to be assembled;

[0022] Hook slider: comprising a slider slidably assembled on a support frame and a hook arranged on the slider, the hook being used to hook the elastic ring, at least three hook sliders are provided and arranged at intervals along the circumference of the elastic ring, each slider being used to be arranged on the periphery of the elastic ring, the hook slider having an initial receiving position for receiving the elastic ring and an assembly position for making a part of the elastic ring be stuck in the clamping groove of the cone tube in the sliding stroke, the hook having a hooking state for hooking the elastic ring when the hook slider moves from the initial receiving position to the assembly position, and also having a disengaging state separated from the elastic ring;

[0023] The hook driving mechanism applies a driving force to the hook to swing toward the hooking state at the initial receiving position so that the hook hooks the elastic ring, and applies a restoring force to the hook to swing toward the unhooking state at the assembly position so that the hook swings toward the unhooking state;

[0024] The hook is fixed to the slider, and there is a swing gap between the slider and the support frame so that the slider can be swingably arranged on the support frame. Under the driving force of the hook driving mechanism, the slider swings forward to the positive limit position and cooperates with the support frame stop to put the hook in a hooking state; under the reset force of the hook driving mechanism, the slider swings backward to the reverse limit position and cooperates with the support frame stop to put the hook in a dehooking state; under the driving force of the hook driving mechanism, the hook slider moves from the initial receiving position to the assembly position; under the reset force of the hook driving mechanism, the hook slider moves from the assembly position to the initial receiving position;

[0025] Alternatively, the hook is swingably assembled on the slider, and the slider is guide-slidably assembled on the support frame, and when the hook is in the hooked state, it cooperates with the slider in the direction of the hook swinging toward the hooked state, so that the hook is kept in the hooked state under the driving force of the hook driving mechanism, and when the hook is in the hooked state, it moves from the initial receiving position to the assembly position under the driving force of the hook driving mechanism; when the hook is in the unhooked state, it cooperates with the slider in the direction of the hook swinging toward the unhooked state, so that the hook is kept in the unhooked state under the resetting force of the hook driving mechanism, and when the hook is in the unhooked state, it moves from the assembly position to the initial receiving position under the resetting force of the hook driving mechanism;

[0026] The spacing between adjacent hooks in the initial receiving position is smaller than that in the assembly position, so that the elastic ring is enlarged and sleeved on the cone tube.

[0027] Beneficial effect: the hook slider receives the elastic ring at the initial receiving position, and the hook rotates to the hooking state under the action of the driving force to hook the elastic ring. Under the action of the driving force, the hook slider drives the elastic ring to move toward the assembly position. When reaching the assembly position, the elastic ring is enlarged by the hook slider and partially stuck in the groove at the large diameter end of the tapered tube. At this time, under the action of the reset force, the hook rotates to the unhooking state, the hook slider is disengaged from the elastic ring, and the reset force drives the hook slider back to the initial receiving position, completing the installation of an elastic ring, and realizing automatic installation of the elastic ring; in the above-mentioned installation process, the elastic ring undergoes elastic deformation and gradually enlarges under the action of the hook, and the distance between the hooks also gradually increases. Under the action of the hook, the elastic ring will not separate from the hook slider, which can effectively prevent the elastic ring from falling off, and realize the automatic installation of the elastic ring.

[0028] Furthermore, the clip feeding device includes two clip vibrating discs, a clip conveying plate, a receiving plate at the end of the clip conveying plate for receiving the clip from the clip conveying plate with an opening opposite to the clip, and a pushing mechanism. The two clip vibrating discs are used to output the clips upright and the clip recesses output by the two clip vibrating discs are arranged relatively to each other. The discharge port of each clip vibrating disc is correspondingly connected to a clip conveying plate, and the clip conveying plates corresponding to the two clip vibrating discs are parallel; the pushing mechanism is arranged at the end of the two clip conveying plates, and is used to push the clips transported from the clip conveying plate to the receiving plate so that the clips are matched to form a conical tube and the conical tube pair is transported to the elastic ring set device. Both sides of the clip conveying plate have stop surfaces for limiting the rotation of the clips so that the clips on the two vibrating tracks remain in a relative state, so that the clips with opposite recesses are relatively matched under the action of the pushing mechanism after being transported to the slideway.

[0029] Beneficial effect: The clip is output upright through the clip vibrating plate, and the notches of the two clips are arranged relatively to each other, which is convenient for subsequent matching to directly form a conical tube. A receiving plate is provided at the end of the clip conveying plate. Two relatively arranged clips are matched on the receiving plate to form a conical tube, and the conical tube is pushed into the elastic ring set device through the pushing structure. The whole process can realize the automatic conveying and matching of the clips, which helps to improve work efficiency and save labor costs. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0054] The elastic ring feeding device of the present invention will be further described below in conjunction with the accompanying drawings.

[0055] The embodiment of the elastic ring feeding device of the present invention is as follows Figure 1 and Figure 2As shown, it includes an elastic ring vibration conveying plate 3 arranged on an operating table 6, the discharge port of the elastic ring vibration conveying plate 3 is connected to a downwardly inclined material guide plate 31, an elastic ring conveyor belt 29 is arranged below the lower end of the material guide plate 31, and the elastic ring conveyor belt 29 is driven by a conveyor belt motor 7. The elastic ring conveyor belt 29 can convey the elastic ring 4 to the assembly position, and the assembly position is inside the frame cover 14.

[0056] The elastic ring vibrating and delivering plate 3 can deliver the elastic ring 4 in an orderly manner. An inclined material guide plate 31 is connected to the discharge port of the elastic ring vibrating and delivering plate 3, so that the elastic ring 4 can slide down smoothly. Since the elastic ring conveyor belt 29 is below the lower end of the material guide plate 31, the elastic ring 4 delivered by the elastic ring vibrating and delivering plate 3 can slide along the material guide plate 31 to the belt surface of the elastic ring conveyor belt 29.

[0057] like Figure 3 and Figure 4 As shown, a semicircular end cap 39 is provided at the end of the guide plate 31 near one end of the elastic ring conveyor belt 29, and the semicircular end cap 39 is provided perpendicular to the plate surface of the guide plate 31. A semicircular hole is also provided on the plate surface of the guide plate 31 near the semicircular end cap 39, and a semicircular supporting guide piece 38 is provided on the hole wall of the semicircular hole. The center of the circle corresponding to the semicircular hole is concentric with the center of the circle corresponding to the semicircular supporting piece 38. The semicircular supporting guide piece 38 is inclined from top to bottom in the conveying direction of the elastic ring conveyor belt 29, and the arcuate edge of the semicircular supporting guide piece 38 and the arcuate hole wall of the semicircular hole form a rubber ring sliding-out gap for the elastic ring to slide out of the guide plate.

[0058] like Figure 1 , Figure 2 and Figure 5 As shown, when the elastic ring 4 moves to the end of the guide plate 31 close to one end of the elastic ring conveyor belt 29, it will not continue to move downward due to the blocking effect of the semicircular end head 39. At the same time, the semicircular edge of the semicircular end head 39 can position the elastic ring 4 so that the elastic ring 4 is just above the semicircular supporting guide plate 38. Under the action of gravity, the elastic ring 4 tilts toward the front end of the elastic ring conveyor belt 29 and gradually slides onto the belt surface of the elastic ring conveyor belt 29.

[0059] In order to better drive the elastic ring 4 that slides onto the elastic ring conveyor belt 29, a stopper for driving the elastic ring to move is provided on the belt surface of the elastic ring conveyor belt 29. The specific stopper is a crescent-shaped pushing block 21. The arc edge of the pushing block 21 is adapted to the inner edge shape of the elastic ring 4 and has a larger contact surface with the elastic ring 4. When driving the elastic ring 4 to move, the elastic ring 4 can maintain an intact shape and prevent the elastic ring 4 from being deformed easily.

[0060] A plurality of push blocks 21 are arranged on the belt surface of the elastic ring conveyor belt 29, and the distance between the arc edges of two adjacent push blocks 21 is equal to the diameter of the outer edge of the elastic ring 4, so that the elastic ring 4 can be hooked by one push block 21 when it falls on the elastic ring conveyor belt 29, and no mutual force is generated between the two adjacent elastic rings 4, thereby preventing the elastic rings 4 from being squeezed and deformed. The two adjacent elastic rings 4 are in contact with each other without a gap, so that the conveyor belt 2 can convey more elastic rings 4 at the same time, which helps to improve the feeding efficiency.

[0061] When the elastic ring 4 moves following the elastic ring conveyor belt 29, it is driven by the pushing block 21 arranged on the belt surface, and does not rely on the elastic ring 4 at the rear end in the moving direction of the elastic ring 4 to push the elastic ring 4 at the front end to move, thereby avoiding the elastic rings 4 from stacking on each other.

[0062] When the elastic ring conveyor belt 29 drives the elastic ring 4 to move to the front end in the assembly tube 6, the pushing block 21 will gradually separate from the elastic ring 4 at the front end. At this time, the elastic ring 4 at the rear end of the elastic ring conveyor belt 29 pushes the elastic ring 4 at the front end of the elastic ring conveyor belt 29, and pushes the elastic ring 4 to the assembly position in the frame cover 14, so as to facilitate the subsequent assembly with the cone tube in the frame cover 14.

[0063] In other embodiments, the material guide plate may not be provided, but the outlet of the elastic ring vibration conveying plate may be tilted, and the elastic ring vibration conveying plate may be directly placed above the elastic ring conveying belt.

[0064] In other embodiments, the material guide plate may also be arranged without being tilted.

[0065] In other embodiments, the stopper may also be a hook or a protrusion disposed on the belt surface of the conveyor belt, and the elastic ring is driven to move by the hook or the protrusion.

[0066] In other embodiments, the protrusion may also have an arc-shaped groove that matches the outer edge of the elastic ring. In this case, the outer edge of the elastic ring can be stuck in the arc-shaped groove, and the elastic ring is pushed to move by the protrusion.

[0067] In other embodiments, the end of the guide plate may not be provided with a semicircular end cap and a semicircular hole, but the end of the guide plate is directly above the elastic ring conveyor belt. When the elastic ring slides off the guide plate, it falls directly on the elastic ring conveyor belt and is transported to the assembly position by the elastic ring conveyor belt.

[0068] The embodiment of the elastic ring set system of the present invention is as follows Figure 6 and Figure 7As shown, the elastic ring fitting system includes an elastic ring feeding device, a clip feeding device and an elastic ring fitting device fixed on an operating table 6. The elastic ring feeding device can convey the elastic ring 4 to the assembly position in the elastic ring fitting device, the clip feeding device can convey the clip to the assembly position corresponding to the elastic ring 4 in the elastic ring fitting device and align to form a cone tube, and the elastic ring fitting device can fit the elastic ring 5 into the card slot at the large diameter end of the cone tube, so as to realize the automatic fitting of the elastic ring.

[0069] The structure of the elastic ring feeding device is the same as that of the above-mentioned elastic ring feeding device, and will not be described in detail here.

[0070] In this embodiment, a conical tube formed by two clamps is taken as an example to illustrate the loading process of the clamp loading device. The clamp loading device includes a clamp vibrating plate fixed on the operating table 6. Since the conical tube in this embodiment is formed by two clamps, two clamp vibrating plates are required to vibrate the two clamps respectively. The specific clamp vibrating plates are the first vibrating plate 1 and the second vibrating plate 2.

[0071] The first vibration feeding plate 1 and the second vibration feeding plate 2 have the same structure. The following description will be made by taking the first vibration feeding plate 1 as an example. The first vibration feeding plate 1 is provided with a spiral vibration feeding track, which is used to support the clip 5 and drive the clip 5 to move forward and spiral upward under the action of vibration. Fig.14 As shown, it is a partial structural diagram of the first vibration disk 1. The vibration feeding track includes a horizontal clip feeding track and a vertical clip feeding track. The horizontal clip feeding track includes a support wall 407 and a side wall 404. In order to form a good support and limiting effect for the clip, a continuous support and limiting structure is arranged on the support wall 407. The support and limiting structure in this embodiment is a support and limiting groove 401 opened on the support wall 407. The support and limiting groove 401 is V-shaped, which can support and limit the outer conical surface of the clip to ensure that the clip can be smoothly transported forward and the clip is not easily vibrated off. The clip that is not supported by the support and limiting groove 401 is easily vibrated off the track and falls back into the vibration disk. The extension direction of the support and limiting groove 401 and the support wall 407 is consistent, so the large end or small end of the clip can move forward.

[0072] Along the moving direction of the clip 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 clip feeding track, wherein one end of the blocking plate 402 is fixed on the side wall 404 and the other end is cantilevered, the blocking plate 402 is arranged horizontally, and the distance from the blocking plate 402 to the supporting wall 407 is less than the length of the clip, so the vertical clip cannot pass through the blocking plate 402 and can only be blocked by the blocking plate 402 and fall into the vibration plate, such as Fig. 22As shown, or blocked and in a horizontal posture, the horizontal clip can continue to be conveyed forward through the blocking plate 402. In this way, the vertical clip is rejected, or the horizontal clip is screened out.

[0073] The transition beam 403 is arranged downstream of the blocking plate 402. The transition beam 403 is a part of the support wall 407. Its width is smaller than the groove width of the clip groove, which is equivalent to a relatively narrow support wall. The length of the transition beam 403 is greater than the clip length L. In this way, when the clip with the internal thread facing upward passes through the transition beam 403, it can be supported and continued to be transported under the action of the support limit groove 401. Fig.14 When the clip with the internal thread facing downward passes through the transition beam 403, it "rides" on the transition beam 403 at first, but it can easily rotate around the transition beam 403 and slide down under the action of vibration, as shown in FIG. Fig. 22 Even if some clips can "ride" on the transition beam 403 steadily, when they continue to move forward, they will hit the end surface of the next support wall (i.e., the stop surface 408) and fall off. In this way, the clips with the internal threads facing upward are selected.

[0074] One end of the fixed baffle 405 is fixed to the side wall 404, and the other end is cantilevered. The movable baffle 409 is installed on the fixed baffle 405 to guide and move in the up and down direction. The fixed baffle 405 is provided with a guide hole for the movable baffle 409 to guide and move up and down. Fig.23 The figure shows a matching form of a fixed baffle and a movable baffle. The guide hole on the fixed baffle 405 is a blind hole with the hole opening facing downward. A spring 415 is arranged between the bottom of the guide hole and the movable baffle 409. One end of the spring 415 is fixed to the bottom of the guide hole and the other end is fixed to the movable baffle 409. The movable baffle 409 is equivalent to being suspended on the fixed baffle 405 by the spring 415. When the movable baffle 409 is subjected to an upward force, the spring 415 can be compressed to move upward.

[0075] The movable baffle 409 includes a material-facing surface 4091 which is tilted in the direction of the incoming material, and before the incoming material, the distance between the bottom end of the material-facing surface 4091 and the support wall 407 is less than the height h of the large end of the clip, so that when the clip with the large end facing forward is incoming, due to the high large end, it will hit the tilted material-facing surface 4091, and then be guided to slide off the feeding track under the action of vibration. At the same time, the distance between the bottom end of the material-facing surface 4091 and the support wall 407 is greater than the height of the small end of the clip, so that when the clip with the small end facing forward is incoming, due to the low small end, it can drill into the bottom of the movable baffle 409, and because the cross section of the clip is in a tilted state when the clip is lying flat, as the clip continues to move forward, the cross section of the clip will exert an upward force on the movable baffle 409, forcing the movable baffle 409 to compress the spring 415 and move upward, and finally the clip can pass through the movable baffle 409, and then the movable baffle 409 is reset under the reaction force of the spring.

[0076] In addition, the side surface of the fixed baffle 405 facing the incoming material direction is an inclined surface 4051, and the inclined surface 4051 is arranged parallel to the material facing surface 4091, and there is a set distance between the fixed baffle 405 and the support wall 407, so that a part of the clip with the big head facing forward and the two sections not at the same height, that is, the clip with one high and one low section and the big head end as a whole being higher, will directly contact the inclined surface 4051 and be guided down by the inclined surface 4051 without being guided down by the moving baffle 409.

[0077] The setting of the inclined surface 4051 is equivalent to sharing part of the responsibilities 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 only the movable baffle 409 is used to block the falling clip, the fixed baffle 405 needs to be set higher, and the movable baffle 409 needs to be set longer, which will cause the weight of the movable baffle 409 to increase, which is not conducive to its upward movement, and even the clip cannot lift it up.

[0078] Taking the vibration plate itself as the reference object, the clamp is moving forward, and the vertical clamp feeding track is set on the right side of the horizontal clamp feeding track and parallel to it. Fig.21 As shown, the vertical clip feeding track includes a supporting surface 413 for supporting the end face of the large end of the clip, and two limiting side walls arranged perpendicular to the supporting surface 413 for preventing the vertical clip from rotating, the two limiting side walls are an inner limiting side wall 412 and an outer limiting side wall 411, and the distance between the inner limiting side wall 412 and the outer limiting side wall 411 matches the height of the large end of the clip.

[0079] The groove 406 is arranged at the end of the horizontal clip feeding track, such as Fig.15As shown, the groove 406 includes a bottom support wall 4061 for supporting the large 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 support limit grooves 401, so as Fig.16 As shown, when the clip with the small head end facing forward moves to the position of the groove 406, since the center of gravity of the clip is backward, the small head end of the clip can pass over the groove 406. At a certain moment, the clip spans across the groove, and its large head end and small head end are both supported on the support limit groove 401.

[0080] like Fig.17 As shown, as the clip continues to move forward, its large head end will overhang above the groove, and due to the unstable center of gravity, its large head end will fall into the groove and become tilted, at which time the large head 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 groove 406 also includes a stop wall 4063 opposite to the side support wall 4062, and the stop wall 4063 stops the large head end of the clip.

[0081] The bottom support wall 4061 gradually tilts from top to bottom toward the support surface 413 and is connected to the support surface 413, so that under the action of its own weight, the clip falling into the groove will slide down along the bottom support wall 4061. Fig.15 As shown, a transition guide wall 414 is provided between the inner limit side wall 412 and the side support wall 4062. The transition guide wall 414 is an arc-shaped wall, which can guide the sliding clip to transition to the support surface 413. Fig.14 As shown, this is equivalent to guiding the clip to turn.

[0082] There is also an arc transition between the outer limit side wall 411 and the stop wall 4063, which helps the clip to transition to the support surface 413. In order to prevent the clip from escaping from the vertical clip feeding track during the transition to the support surface 413, an upwardly folded upper edge 410 is provided at the top of the outer limit 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 large end of the clip from escaping from the vertical clip feeding track during the turning process. Fig.18 and Fig.19 shown.

[0083] As the 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 large end of the clip, the clip gradually becomes a vertical posture on the support surface 413, and the orientation of the notches is consistent, such as Fig. 20 and Fig.21It should be noted that, through the reasonable design of the vibration plate structure, the notches of the clips output by the first vibration plate 1 and the second vibration plate 2 can be arranged relatively, and the structural principles adopted by each vibration plate to prevent the vertical clips from passing, prevent the clips with the internal threads facing downward from passing, prevent the clips with the large head facing forward from passing, and convert from horizontal to vertical are all the same.

[0084] The outlets of the first vibrating plate 1 and the second vibrating plate 2 are both connected to the clip conveying plate 18, the clips output through the first vibrating plate 1 and the second vibrating plate 2 are converted into vertical, and the openings are arranged relatively, and a partition 19 vertically supported on the clip conveying plate 18 is arranged in the middle of the clip conveying plate 18, and the partition 19 forms a stop surface for limiting the rotation of the clip, under the action of the first vibrating plate 1 and the second vibrating plate 2, the large diameter end of the clip is supported on the clip conveying plate 18, and the openings of the clip are facing the partition 19, and the openings of the clips delivered by the first vibrating plate 1 and the second vibrating plate 2 are arranged relatively.

[0085] The clip conveying plate 18 is not provided with a conveying device, and the clip is only conveyed by the first vibrating conveying plate 1 and the second vibrating conveying plate 2. The clip at the front end of the clip moving direction is pushed forward by the clip 5 at the rear end. Due to the limitation of the partition 19, the clip will not rotate circumferentially on the clip conveying plate 18, nor will it fall, so that the clip is matched at the end of the clip conveying plate 18 to form a cone. The clip conveying plate 18 in this embodiment has an inclined section arranged downwardly, which facilitates the clip to move toward the end of the clip conveying plate 18. The structure of the above-mentioned vibration feeding plate only gives a specific form. The vibration plate should include the following structures: a horizontal clip feeding track, which is used to transport the horizontal clip under the action of vibration. The horizontal clip feeding track is provided with a support and limiting structure for supporting the outer conical surface of the clip and enabling its end to move forward; a vertical clip feeding track, which is used to transport the vertical clip under the action of vibration. The vertical clip feeding track includes a supporting surface for supporting the end surface of the large end of the clip, and two limiting side walls arranged perpendicular to the supporting surface for preventing the vertical clip from rotating. The spacing between the two limiting side walls matches the height of the large end of the clip; wherein, the horizontal clip feeding track A groove is provided at the end of the material track, and the length of the groove is smaller than the length of the clip, so that the large end of the clip can fall into the groove and make the clip inclined. The groove includes a bottom support wall for supporting the large end of the clip and a side support wall for supporting the outer cone surface of the clip. The support surface is located on the left or right side of the bottom support wall, and the bottom support wall gradually tilts toward the support surface from top to bottom, so that the clip falling into the groove can slide down along the bottom support wall of the groove. The bottom support wall is connected to the support surface, and a transition guide wall is provided between the side support wall and the limiting side wall, so that the sliding clip can be guided to the support surface and become a vertical posture. For example: the outer limiting side wall may not be provided with an upward turning edge, in which case the outer limiting side wall itself may be used to limit the large end of the clip; the upward turning edge may not be arc-shaped, but straight; the vertical clip feeding track may be perpendicular to the horizontal clip feeding track, the extension direction of the support surface of the vertical clip feeding track is perpendicular to the support limiting groove, and the support surface may be located on the left side of the groove or on the right side of the groove. In this case, after the clip slides off the bottom support wall of the groove, it can directly slide onto the support surface of the vertical clip feeding track without turning, etc. Of course, in other embodiments, the vibrating feeding plate in the prior art may also be used.

[0086] The end of the clip conveying plate 18 is provided with a receiving plate for receiving the clip 5 opposite to the opening and a pushing cylinder 8. The pushing direction of the pushing cylinder 8 is perpendicular to the moving direction of the clip on the clip conveying plate 18, and is used to push the formed conical tube into the elastic ring set device. When the piston of the pushing cylinder 8 pushes the conical tube, the two clips forming the conical tube are arranged opposite to each other and will not be misaligned.

[0087] In this embodiment, the conical tube is transported to the assembly position at the bottom of the elastic ring set device, and the elastic ring 4 is transported to the assembly position corresponding to the conical tube at the top of the elastic ring set device. The elastic ring 4 is higher than the conical tube in the elastic ring set device, which is convenient for subsequent set.

[0088] Elastic ring set device such as Figure 8 As shown, it includes a shell frame cover 14, a support guide mold 15 arranged in the shell frame cover 14, and a push hook guide groove cone sleeve 32 is sleeved on the outside of the support guide mold 15.

[0089] The frame cover 14 is cylindrical as a whole, and has a flange at the bottom for fixing to the operating table 6. The bottom of the shell of the frame cover 14 is also provided with an inlet for the cone tube to enter the interior of the frame cover 14 and an outlet for the cone tube to be sent out from the interior of the frame cover 14. The top of the frame cover 14 is also provided with a top opening for inserting the push hook cover 16.

[0090] The push hook cover 16 is guided and moved in cooperation with the inner side wall of the top opening in the up-down direction; the push hook cover 16 also has openings corresponding to the inlet and outlet at the bottom of the frame cover 14 for the cone tube to pass through.

[0091] The support guide mold 15 is a cylindrical support fixed on the operating table 6, and its lower end is a tapered cylinder with gradually increasing radial dimensions from top to bottom. The tapered cylinder part has openings corresponding to the inlet and outlet at the bottom of the shell cover 14 for the conical tube to pass through. The outside of the support guide mold 15 is also covered with a push hook guide groove cone sleeve 32, which also has openings corresponding to the inlet and outlet at the bottom of the shell cover 14 for the conical tube to pass through; an annular gap is formed between the push hook guide groove cone sleeve 32 and the support guide mold 15, and the annular gap forms an inclined extending linear slideway 30. The push hook guide groove cone sleeve 32 in this embodiment is formed by two oppositely arranged parts, which is convenient for assembly with the support guide mold 15. The push hook guide groove cone sleeve 32 is configured as two parts mainly for the convenience of assembly. Since the size of the bracket guide mold 15 is relatively large, it is not easy to install if the push hook guide groove cone sleeve 32 is configured as an integral part. Of course, in other embodiments, when the size of the bracket guide mold is smaller, the push hook guide groove cone sleeve can also be configured as an integral part, so that the push hook guide groove cone sleeve has better structural strength.

[0092] The frame cover 14, the support guide mold 15, the push hook guide groove cone sleeve 32 and the side of the push hook cover 16 close to the elastic ring conveyor belt 29 are all provided with corresponding openings, so that the elastic ring conveyor belt 29 can be extended into the support guide mold 15 to convey the elastic ring to the assembly position inside the support guide mold 15. The opening on the push hook cover 16 is larger in the up and down direction, so that the push hook cover 16 can avoid the elastic ring conveyor belt 29 when moving up and down.

[0093] The elastic ring set device also includes a hook slider 12 for hooking the elastic ring 4. Fig.10 , Fig.11and Fig.12 As shown, the hook slider 12 has a slider 26 that is slidably matched with the linear slide 30 and a hook 25 that is fixedly connected to the slider 26. A hook groove for hooking the elastic ring 4 is provided at one end of the hook 25. The notch of the hook groove faces the elastic ring 4 at a predetermined position. An arc-shaped groove 28 is provided on the groove wall facing the center line of the bracket guide mold. The other end of the hook 25 has an extension section 27 that extends out of the cone. The groove 28 is recessed toward the center line of the bracket guide mold 15, which can prevent the elastic ring 4 hooked on the hook 25 from being disengaged from the hook 25.

[0094] The side wall of the push hook guide groove cone sleeve 32 is also provided with an extension section sliding groove for the extension section 27 to pass through. The extension section sliding groove extends in the up-down direction and penetrates the side wall of the push hook guide groove cone sleeve 32 from the inside to the outside. The extension section 27 and the extension section sliding groove are guided and moved in the extension direction of the side wall of the push hook guide groove cone sleeve 32; the conical cylinder part of the bracket guide mold 15 is also provided with a hook sliding groove corresponding to the extension section sliding groove 34. The extension hook sliding groove extends in the up-down direction and penetrates the cylinder wall of the bracket guide mold 15 from the inside to the outside. The hook 25 and the hook sliding groove are guided and moved in the extension direction of the conical cylinder side wall.

[0095] The width of the slider 26 is greater than the width of the extension section 27 and the hook, so that when the slider 26 slides in the linear slide, the slider 26 cannot pass through the hook sliding groove and the extension section sliding groove, so that the slider 26 can only move in the linear slide 30 along the extension direction of the main push.

[0096] like Figure 7 , Figure 8 , Fig.10 As shown, the slider 26 of the hook slider 12 is slidably assembled in the linear slide 30. The sliding stroke of the hook slider 12 has an initial receiving position for receiving the elastic ring 4 in a predetermined position, and an assembly position in which a part of the elastic ring 4 is inserted into the groove of the cone tube. The hook 25 has a hooking state in which the elastic ring 4 is hooked when the hook slider 12 moves from the initial receiving position to the assembly position, and also has a disengaging state separated from the elastic ring 4.

[0097] The slider 26 and the linear slide 30 are guided and matched in the extension direction of the cone of the bracket guide mold 15, and the slider 26 and the linear slide 30 are clearance matched in the radial direction of the bracket guide mold 15, so that there is a swing gap between the slider 26 and the bracket guide mold 15, and the slider 26 can be swingably configured on the bracket guide mold 15.

[0098] The linear slide 30 has a swinging fitting section that swings relative to the slider 26 when the hook slider 12 is in the assembly position and the initial receiving position. The size of the swinging fitting section of the guide groove is larger than the size of the slider 26 so that the slider 26 can swing, so that the hook slider 12 can be swingably configured on the bracket guide mold 15; the linear slide 30 also has a guiding fitting section that guides and slides with the slider 26, and the slider 26 and the linear slide 30 are guided and fitted in the extension direction of the cone of the bracket guide mold 15.

[0099] When the hook slider 12 is in the initial receiving position, the slider 26 cooperates with the swinging matching section of the linear slide 30, and can swing forward to the forward limit position to form a stopper match with the swinging matching section. During this process, the hook 25 moves toward the elastic ring 4, and the hook 25 is converted from the unhooked state to the hooked state of the elastic ring 4. When the hook slider 12 is in the assembly position, the slider 26 cooperates with the swinging matching section of the linear slide 30, and can swing backward to the reverse limit position to form a stopper match with the swinging matching section. During this process, the hook 25 is disengaged from the elastic ring 4, and the hook 25 is converted from the hooked state of the elastic ring 4 to the unhooked state.

[0100] The elastic ring mounting device also includes a hook driving mechanism for applying a force to the extension section 27 to drive the hook 25 to swing and move.

[0101] The hook driving mechanism in this embodiment includes a hook driving member for applying a driving force to the hook 25 and an elastic member for applying a restoring force to the hook.

[0102] A pulley 13 is provided on the end surface of the bottom of the push hook cover 16. When the push hook cover 16 moves downward, the pulley 13 presses on the extended section 27 of the hook slider 12 and pushes the hook slider 12 to move downward. A hook driving member is connected to the top of the push hook cover 16. Specifically, Fig.13 As shown, the hook driving member is a top pressure cylinder 17, which is fixed to the top of the bracket guide mold 15. The top pressure cylinder 17 and the bracket guide mold 15 are fixedly connected by flange bolts. A screw hole for installing the top pressure cylinder 17 is provided on the top of the push hook cover 16. Bolts are passed through the screw holes and fixedly connected to the piston rod 40 of the top pressure cylinder 17, so that the top pressure cylinder 17 can drive the push hook cover 16 to move up and down when it is active.

[0103] The elastic member is a spring 11 located between the push hook cover 16 and the bracket guide mold 15 , one end of the spring 11 is connected to the hanging hole 24 of the hook slider 12 , and the other end is connected to the bracket guide mold 15 above the hook slider 12 .

[0104] The hanging hole 24 is a reset point that bears the reset force, and the extended section 27 has a driving point that bears the driving force. The reset point is between the driving point and the hook groove, so that the driving point and the hook groove form a lever with the reset point as the fulcrum, which can more easily move the hook slider to the assembly position.

[0105] When assembling the elastic ring set device, first fix the bottom of the bracket guide mold 15 on the operating table 6, then insert the hook 25 of the hook slider 12 into the hook sliding groove, then buckle the two push hook guide groove cone sleeves 32 on the outside of the bracket guide mold 15 and make the extended section 27 in the extended section sliding groove, then fix the push hook guide groove cone sleeve 32 on the operating table 6, install the spring 11 on the bracket guide mold 15 and the hook slider 12, fix the top pressure cylinder 17 on the top of the bracket guide mold 15, use bolts to connect the piston rod 40 and the push hook cover 16, finally, the shell frame cover 14 is sleeved on the outside of the push hook guide groove cone sleeve 32 by the upper end of the push hook cover 16, and the bottom of the shell frame cover 14 is fixed to the operating table 6.

[0106] like Figure 5 and Figure 6 As shown, in the present embodiment, four hook sliders 12 are provided, and a supporting block 20 is provided on the cylinder wall of the bracket guide mold 15 between two adjacent hook sliders 12, for supporting the elastic ring 4 entering into the bracket guide mold 15, and the supporting block 20 has an arc-shaped side surface facing the axis of the bracket guide mold 15, so as to facilitate the separation of the elastic ring 4 from the supporting block 20.

[0107] The elastic ring 4 is conveyed to the bracket guide mold 15 by the elastic ring conveyor belt 29. During this process, the elastic ring 4 is partially separated from the elastic ring conveyor belt 29. The elastic ring 4 on the elastic ring conveyor belt 29 pushes the elastic ring 4 that is partially separated from the elastic ring conveyor belt 29 to push the elastic ring onto the supporting block 20. Due to the support of the supporting block 20 and the hook 25, and the elastic ring 4 has a certain anti-deformation ability, the elastic ring 4 has a certain movement speed during the conveying process and can reach the predetermined position.

[0108] When the hook slide block 12 is in the initial receiving position, the pressing oil cylinder 17 pushes the hook cover 16 downward, and the pulley 13 on the hook cover 16 presses the extension section 27. The extension section 27 swings downward with the hook fulcrum 22 as the fulcrum, driving the hook 25 to swing upward, hooking the elastic ring 4 at the predetermined position, and the hook 25 enters the hooking state from the unhooking state. In actual use, after the elastic ring reaches the predetermined position, the hook slide block 12 can move upward from the bottom to the bottom. Figure 8 position, at this time, in the initial state, the hook slider hooks the elastic ring.

[0109] The driving force is continuously applied to the extension section 27 by the push cylinder 17, and the hook slider 12 moves downward against the elastic force of the spring 11, and the slider forms a sliding fit with the linear slide 30. Since the lower end of the bracket guide mold 15 is a cone, the linear slide 30 inside it is also arranged obliquely. During the movement of the slider along the linear slide 30, the distance between adjacent hooks 25 gradually increases, thereby enlarging the elastic ring 4 and deforming the elastic ring 4. The edge of the elastic ring 4 gradually changes from a curved edge to a straight edge. The side of the support block 20 is an arc-shaped side. The elastic ring 4 gradually separates from the support block 20. At the same time, the hook 25 applies a downward force to the elastic ring 4, so that the elastic ring 4 is completely separated from the support block 20. The groove 28 on the hook 25 can ensure that the elastic ring 4 is prevented from being separated from the hook 25 during the movement of the hook 25.

[0110] In the process that the hook 25 drives the elastic ring 4 to continue to move downward to the assembly position, the spring 11 is also stretched, and the elastic ring 4 contacts the outer wall of the cone tube. When part of the elastic ring 4 is stuck in the groove of the cone tube, the push cylinder 17 cancels the driving force on the extension section 27. Under the action of the upward reset force provided by the spring 11, the extension section 27 of the hook 25 swings upward with the unhooking fulcrum 23 as the fulcrum, driving the hook 25 to swing downward, and the hook 25 is converted from the hooking state to the unhooking state. Due to the transition of the arc-shaped groove 28, the hook 25 is easily separated from the elastic ring 4 when swinging downward. At the same time, the groove on the cone tube also has a certain blocking effect on the elastic ring, so that the elastic ring 4 is separated from the hook and completely stuck in the groove of the cone tube. At the same time, the hook slider 12 moves upward to the initial receiving position under the action of the spring 11, completing the assembly of a cone tube.

[0111] After the assembly of a cone tube is completed, the assembled cone tube is pushed out of the support guide mold 15 by the unassembled cone tube under the action of the push cylinder 8, and enters the cone tube container 9 after being counted by the code counting device 10.

[0112] The elastic ring fitting system of the present invention also includes a numerical control intelligent control system for controlling the clip feeding device, the elastic ring conveying device and the elastic ring fitting device, so that the entire feeding and fitting can be performed automatically, saving labor costs.

[0113] The elastic ring assembly system of the present invention uses a hook to swing and hook the elastic ring at an initial receiving position. When the hook drives the elastic ring to move to an assembly position, the distance between two adjacent hooks becomes larger, and the elastic ring is stretched. The hook is separated from the elastic ring by swinging at the assembly position, so that the elastic ring is clamped in the clamping groove of the cone tube under the action of tensioning force to complete the assembly.

[0114] In the above-mentioned embodiment of the elastic ring set system, the hook is fixed to the slider, and there is a certain gap between the slider and the linear slide to realize the swing of the hook; in other embodiments, the hook can also be swingably assembled on the slider, and the slider guide sliding assembly is on the bracket guide mold, and when the hook is in the hooked state, it cooperates with the slider in the direction of the hook swinging toward the hooked state, so that the hook is kept in the hooked state under the driving force of the hook driving mechanism, and when the hook is in the hooked state, it moves from the initial receiving position to the assembly position under the driving force of the hook driving mechanism; when the hook is in the unhooked state, it cooperates with the slider in the direction of the hook swinging toward the unhooked state, so that the hook is kept in the unhooked state under the reset force of the hook driving mechanism, and when the hook is in the unhooked state, it moves from the assembly position to the initial receiving position under the reset force of the hook driving mechanism.

[0115] In the embodiment of the above-mentioned elastic ring set system, the lower end of the bracket guide mold is a tapered cylinder and the large diameter end support is set on the operating table. In other embodiments, the bracket guide mold can also be a straight cylinder with a thicker cylinder wall. An inclined linear slide is arranged inside the cylinder wall of the straight cylinder, so that the spacing between the hook sliders gradually increases during the movement of the slider.

[0116] In the above-mentioned embodiment of the elastic ring set system, the slideway that slides with the slider is a straight slideway. In other embodiments, it can also be an arc-shaped slideway, or two straight slideways are connected by a smooth transition section. However, no matter which type of slideway it is, it is necessary to ensure that the distance between two adjacent hooks in the assembly position is greater than the distance in the initial receiving position, so that the elastic ring can be stretched and enlarged.

[0117] In the above-mentioned embodiment of the elastic ring set system, the bracket guide mold is cylindrical; in other embodiments, the bracket guide mold can also be a frame structure, and a slideway that cooperates with the slider guide sliding is provided on the frame structure.

[0118] In the above-mentioned embodiment of the elastic ring set system, the linear slide is arranged inside the cylinder wall of the bracket guide mold; in other embodiments, the linear slide can also be arranged inside the cylinder wall of the bracket guide mold, in which case it is not necessary to arrange the extended section on the hook slider, but it is necessary to arrange a connecting section between the slider and the hook, and the hook driving mechanism applies driving force and reset force to the connecting section. Alternatively, two sliders are arranged, clamped on both sides of the cylinder wall, and form a guide match with the cylinder wall.

[0119] In the above-mentioned embodiment of the elastic ring set system, the hook driving mechanism includes a hook driving member and an elastic member. In other embodiments, only one driving member that can move back and forth may be provided. At the initial receiving position, the driving member applies a driving force to the hook slider to make the hook swing to the hooking state and move toward the assembly position; at the assembly position, the driving member applies a reset force to the hook slider to make the hook swing to the unhooking state and move to the initial receiving position.

[0120] In the above-mentioned embodiment of the elastic ring set system, a supporting block is provided on the bracket guide mold. In other embodiments, the supporting block may not be provided, and the elastic ring is supported only by the upper end surface of the hook. When the elastic ring falls completely into the hook groove, the hook swings to the hooking position.

[0121] In the above-mentioned embodiment of the elastic ring assembly system, the outlets of the first vibrating plate and the second vibrating plate are connected to the same clip conveying plate. In other embodiments, a clip conveying plate can be connected to the outlets of the first vibrating plate and the second vibrating plate respectively, and the two clip conveying plates are parallel to each other.
