Description

Technical Field

[0001] The present invention relates to the technical field of marking equipment, and in particular to a guide wire synchronous feeding device and a feeding method. Background Art

[0002] With the continuous advancement of medical technology, guidewires are increasingly used in interventional procedures. As an important medical device, guidewires are commonly used in procedures such as vascular intervention and catheter insertion. During the guidewire production process, marking is required on the surface of the guidewire for identification or model identification.

[0003] At present, marking equipment is usually required for guide wire marking. During the marking process, the guide wire is loaded and unloaded by a robot or manually. Since the guide wire has a small diameter and a long length, multiple groups of robots may be required to cooperate with each other, resulting in a complex robot collaborative action path, which can easily cause the guide wire to deform or even break during loading and unloading. The robot or manual operation method can usually only process a single guide wire at a time. Some marking equipment in the existing technology also uses an automatic loading mechanism for loading. However, the automatic loading mechanism can only load a single wire. In addition, in order to ensure the accuracy of guide wire marking, it is necessary to make the initial position of the end of each guide wire the same when it is placed.

[0004] Therefore, in the existing marking and loading methods, the robot, operator or automatic loading mechanism needs to repeatedly perform a series of actions such as picking up materials, placing, positioning and aligning. The repetitive single-wire operation method will significantly prolong the guide wire marking time and reduce the overall operating efficiency. In addition, when loading a single wire, it is necessary to perform individual positioning and alignment, which often makes it difficult to ensure the accuracy and consistency of the alignment of different guide wires, and it is easy to introduce human errors, which may affect the reliability and accuracy of subsequent guide wire marking.

The feed mechanism causes the plurality of guide wires to sequentially fall into the plurality of conveyor troughs. The feed assembly is configured to allow the guide wires to enter the hopper assembly from the same position. As the guide wires slide from the hopper assembly toward the discharge hole, the alignment assembly is triggered to ensure that the ends of the guide wires are in the same position when they fall from the discharge hole.

[0057] A guide wire synchronous loading device provided by an embodiment of the present invention is arranged at the front end of the guide wire marking equipment. The guide wire is placed into the hopper assembly manually or by a robot. The guide wire can enter the conveying trough from the hopper assembly, with the tail end of the guide wire in the rear conveying trough and the head end of the guide wire in the front conveying trough. The hopper assembly is driven by the discharge drive part to align with multiple conveying troughs in sequence, and a guide wire can be placed in each conveying trough, so that multiple guide wires can be loaded simultaneously. Among them, the guide wire is first placed in the feeding assembly, and when the guide wire passes through the feeding assembly, multiple guide wires fall into the hopper assembly from the same position; then, the guide wire drives the alignment assembly to start while sliding toward the lower hole in the hopper assembly, and the alignment assembly is used to make the ends of multiple guide wires in the same position, and then they fall from the lower hole into the conveying trough; finally, the delivery drive unit drives the multiple guide wires to move back and forth in the first direction at the same time, so that the initial positions of the multiple guide wires can be kept consistent and after the ends extend out of the conveying rail, the multiple guide wires can be simultaneously conveyed to the guide wire marking equipment to complete the loading, which is beneficial to improving the loading and supply efficiency of the guide wire marking; at the same time, the positioning mechanism is used to keep the ends of the multiple guide wires aligned before being conveyed to the marking equipment, which can effectively avoid the problem of inconsistent alignment accuracy caused by separate positioning and alignment during single loading and delivery, which is beneficial to improving the accuracy of guide wire marking.

[0058] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0059] like Figures 1 to 8As shown, an embodiment of the present invention provides a guide wire synchronous feeding device, which is used in the scenario of guide wire feeding during automatic guide wire marking. Through structural improvements, the present invention can realize the loading of multiple guide wires at the same time, and at least has the advantages of improving operating efficiency and marking accuracy.

[0060] A guide wire synchronous feeding device provided in an embodiment of the present invention can be arranged at the feeding end of the guide wire marking equipment. A clamping feeding mechanism is arranged at the rear end of the guide wire synchronous feeding device. After the guide wire synchronous feeding device is used to align and position multiple guide wires, the clamping feeding mechanism is used to simultaneously feed the multiple guide wires into the guide wire marking equipment for marking. After the marking is completed, the clamping feeding mechanism then takes the multiple guide wires out of the guide wire marking equipment at the same time.

[0061] like Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, in this embodiment, the guide wire synchronous feeding device includes a mounting base plate 1, a conveyor rail 2, a feeding mechanism 3 and a delivery mechanism 4. The conveyor rail 2 is provided on the mounting base plate 1 and extends along the first direction. A plurality of conveying grooves 21 are provided on the conveyor rail 2 at intervals along the second direction. The conveying grooves 21 extend along the first direction, and the first direction is perpendicular to the second direction. The conveyor rail 2 includes a front conveyor rail 22 and a rear conveyor rail 23 provided on both sides of the mounting base plate 1; the feeding mechanism 3 includes at least a hopper assembly 31 provided above the conveyor rail 2 and a discharge drive unit 32 for driving the hopper assembly 31 to move along the second direction. The hopper assembly 31 has a discharge hole, and the guide wire falls from the discharge hole into the conveying groove 21; the delivery mechanism 4 is provided between the front conveyor rail 22 and the rear conveyor rail 23. The delivery mechanism 4 includes at least a delivery clamp 43. A plurality of delivery clamps 43 are provided at intervals along the first direction, and the plurality of delivery clamps 43 correspond one to one to the plurality of conveying grooves 21.

[0062] Specifically, the guide wire synchronous feeding device may include a frame, a mounting base 1 is fixed on the frame, the mounting base 1 may be a rectangular plate structure, the first direction is the length direction of the mounting base 1, the conveying rail 2 is fixed on the upper end surface of the mounting base 1 and extends along the first direction; a plurality of conveying grooves 21 are spaced apart on the conveying rail 2, the conveying groove 21 may be a V-shaped groove, which is convenient for the guide wire to enter the conveying groove 21, and the bottom of the conveying groove 21 may be a semicircular groove to prevent the guide wire from being stuck in the conveying groove 21; the feeding mechanism 3 is arranged just above the conveying rail 2, and the guide wire can be A robot or a person puts the guide wires into the hopper assembly 31, and then the guide wires enter the conveying trough 21 from the hopper assembly 31. The discharge drive unit 32 can drive the hopper assembly 31 to align with each conveying rail 2 in sequence, so that the guide wires can be placed in each conveying trough 21; multiple delivery clamps 43 can each clamp a guide wire, and then the delivery drive unit 42 drives the sliding seat 41 to move back and forth along the first direction, so that the ends of the multiple guide wires extend out of the conveying rail 2, and the clamping and loading mechanism at the rear end clamps the multiple guide wires for loading, so that multiple guide wires can be loaded at the same time.

[0063] At the same time, the conveying rail 2 can be divided into a front conveying rail 22 and a rear conveying rail 23. When the guide wire enters the conveying groove 21, the end of the guide wire is located at the rear conveying rail 23, which can avoid the rear end of the guide wire from being suspended in the air, making it easier for the guide wire to be delivered smoothly and complete loading.

[0064] Furthermore, the synchronous guide wire feeding device also includes a positioning mechanism 5. The positioning mechanism 5 is provided on the hopper assembly 31 and includes a feed assembly 51 and an alignment assembly 52. ​​The feeding mechanism 3 causes multiple guide wires to fall into the multiple conveying troughs 21 in sequence. The feed assembly 51 is used to allow the guide wires to enter the hopper assembly 31 from the same position. As the guide wires slide down from the hopper assembly 31 toward the lower feed hole, the alignment assembly 52 is triggered to ensure that the ends of the guide wires are in the same position when they fall from the lower feed hole.

[0065] For example, the guide wire is first placed in the feed assembly 51. When the guide wire passes through the feed assembly 51, multiple guide wires fall into the hopper assembly 31 from the same position. Afterwards, the guide wire drives the alignment assembly 52 to start while sliding down the feed hole in the hopper assembly 31. The alignment assembly 52 is used to make the ends of multiple guide wires in the same position before they fall from the feed hole into the conveying trough 21. The delivery drive 42 can drive multiple guide wires to move simultaneously in the first direction, so that the ends of multiple guide wires can extend out of the conveying rail 2. Afterwards, the rear-end clamping and loading mechanism clamps multiple guide wires for loading, thereby achieving simultaneous loading of multiple guide wires. Among them, the alignment mechanism 5 is used to keep the ends of multiple guide wires aligned before loading, which can effectively avoid the problem of inconsistent alignment accuracy caused by separate positioning and alignment when loading a single guide wire. There is no need to perform separate alignment during feeding, which greatly improves the feeding speed and is also conducive to improving the reliability and accuracy of the guide wire during marking.

[0066] like Figure 1 、 Figure 2 As shown, in this embodiment of the present invention, the discharge drive unit 32 is disposed on the mounting base 1, and the silo assembly 31 includes a silo seat 311, a fixed silo plate 312, and a movable silo plate 313. The silo seat 311 is connected to the driving end of the discharge drive unit 32; the fixed silo plate 312 is fixedly connected to the silo seat 311; and the movable silo plate 313 is movably connected to the silo seat 311. The fixed silo plate 312 and the movable silo plate 313 are both inclined and form an acute angle. The bottom of the movable silo plate 313, near the side of the fixed silo plate 312, is provided with an inclined surface. The inclined surface is parallel to the plate surface of the fixed silo plate 312, and there is a gap to form a discharge hole.

[0067] Specifically, the discharge drive unit 32 is used to drive the silo seat 311 to reciprocate along the second direction. The silo seat 311 is located above the conveyor rail 2 and can be connected to the mounting base 1 through the discharge drive unit 32. The discharge drive unit 32 is used to drive the silo seat 311 to move along the second direction. The silo seat 311 can be provided with mounting holes, and the fixed silo plate 312 and the movable silo plate 313 are provided in the mounting holes. The fixed silo plate 312 and the movable silo plate 313 are both connected to the silo seat 311. , and the fixed hopper plate 312 and the movable hopper plate 313 are arranged along the first direction; the fixed hopper plate 312 and the movable hopper plate 313 are symmetrically and inclined, forming a V-shaped space. The robot or operator can place the guide wire into the V-shaped space. The inclined surface at the bottom of the movable hopper plate 313 is parallel to the plate surface of the fixed hopper plate 312. Between the inclined surface and the plate surface of the fixed hopper plate 312 is a discharge hole. The width of the discharge hole can be greater than or equal to the diameter of the guide wire. The guide wire can fall from the discharge hole into the conveying trough 21. Among them, the discharge drive unit 32 can drive the hopper seat 311 to move along the second direction, so that the discharge hole can be located directly above each conveying trough 21 in turn, and then a guide wire can be placed in each conveying trough 21, which can reduce the burden on the operator.

[0068] Furthermore, the silo assembly 31 further includes a silo plate adjusting member 314 , which is connected to the silo seat 311 , and a driving end of the silo plate adjusting member 314 is connected to the movable silo plate 313 for driving the movable silo plate 313 to move along the second direction.

[0069] Specifically, the movable plate 313 is movably connected to the hopper base 311 via a plate adjustment member 314. The plate adjustment member 314 can move the movable plate 313 toward or away from the fixed plate 312. For example, in different interventional procedures, the guidewires used may have different diameters. Therefore, the plate adjustment member 314 can be used to move the movable plate 313 in the second direction, thereby adjusting the width of the feed hole to accommodate guidewires of varying diameters. The plate adjustment member 314 can be an electric push rod or a pneumatic cylinder, which is not specifically limited in the present invention.

[0070] Exemplarily, the discharge drive unit 32 may include a slide rail and a drive member. The slide rail is fixed to the mounting base 1 and extends in a first direction. The hopper seat 311 is slidably connected to the slide rail. The drive member is fixed to the mounting base 1, and the drive end of the drive member is connected to the hopper seat 311. The drive member can be a cylinder, a motor, etc. When the drive member is activated, it drives the hopper seat 311 to slide in a second direction, thereby aligning the discharge hole with each conveying trough 21 in sequence, facilitating the placement of guide wires in multiple conveying troughs 21.

[0071] like Figure 4 、 Figure 5 、 Figure 6 As shown, in an embodiment of the present invention, the feed assembly 51 is connected to the movable bin plate 313 , the alignment assembly 52 is connected to the fixed bin plate 312 , and the feed assembly 51 includes a discharge trough 511 , a limiting slide 512 and a feed roller 514 . The discharge chute 511 is connected to the movable storage plate 313. The discharge chute 511 has an inlet and an outlet. The discharge chute 511 is gradually tilted downward in the direction from the inlet to the outlet, and the outlet faces the fixed storage plate 312; the limiting slide 512 is slidably arranged in the discharge chute 511, and there are two limiting slides 512. The distance between the two limiting slides 512 gradually decreases in the direction from the inlet to the outlet; the feeding roller 514 is connected to the inner side of the limiting slide 512 through the fixed seat 513. The two limiting slides 512 are both connected to the feeding roller 514. The feeding roller 514 is rotatably connected to the fixed seat 513, and the axis of the feeding roller 514 is gradually tilted in the direction approaching the limiting slide 512.

[0072] Specifically, the discharge trough 511 can be a shell structure with two sides open, one end of the discharge trough 511 is open as the feed port, and the other end is open as the discharge port, the diameter of the feed port is larger than the diameter of the discharge port, and the thickness of the discharge trough 511 gradually decreases from one side of the discharge port and extends to the middle, and remains the same from the middle to the discharge port, the discharge trough 511 is gradually tilted downward from the feed port to the discharge port, the discharge port of the discharge trough 511 faces the fixed warehouse plate 312, the guide wire enters the discharge trough 511 from the discharge port, and falls from the discharge port to the surface of the fixed warehouse plate 312; two limiting slides 512 are slidably set in the discharge trough 511, and the position and spacing of the two limiting slides 512 can be adaptively adjusted according to the length and falling position of the guide wire. 12 is composed of an inclined section and a parallel section, the inclined section is located inside the discharge trough 511, the spacing between the two inclined sections gradually decreases, and the spacing between the two parallel sections may be greater than or equal to the length of the guide wire; each limiting slide 512 is connected to a fixed seat 513, the fixed seat 513 is located on the inner side of the limiting slide 512, and the feed roller 514 is rotatably connected to the fixed seat 513, the feed roller 514 is set from the feed port to the discharge port, and it gradually tilts toward the direction close to the limiting slide 512, that is, the spacing between the feed rollers 514 on both sides gradually increases from the feed port to the discharge port, the distance between the end face of the feed roller 514 and the bottom surface of the discharge trough 511 may be equal to the diameter of the guide wire, and a motor for driving the feed roller 514 to rotate may be provided on the fixed seat 513. When the guide wire is placed into the discharge trough 511 by a robot or manually, the guide wire slides from the inlet to the outlet. When the guide wire slides under the feed roller 514, the feed rollers 514 on both sides rotate. While driving the guide wire to move toward the outlet, the guide wire can be stretched toward both ends along the length direction, so as to straighten the bent guide wire. When the guide wire slides to the outlet, the two ends can be close to the limiting slides 512 on both sides, so that the position of the guide wire can be kept the same when it falls from the discharge hole.

[0073] It should be noted that the feed roller 514 can be a roller made of a soft material. The diameter of the feed roller 514 gradually increases from the feed inlet to the discharge outlet, then remains constant for a period of time before gradually decreasing. This can straighten a bent guide wire without exerting significant tension along the length of the guide wire, thereby ensuring the integrity of the guide wire.

[0074] like Figure 4 、 Figure 7As shown, in an embodiment of the present invention, a recess 3121 is formed at the bottom of the fixed hopper plate 312, and the alignment assembly 52 includes a blanking roller 521, an alignment drive roller 522, and a telescopic member 523. The blanking roller 521 is connected to the fixed hopper plate 312, and is tooth-shaped. A plurality of blanking rollers 521 are spaced apart along the first direction. The plurality of blanking rollers 521 are rotatably connected to the fixed hopper plate 312 via a rotating shaft; the alignment drive roller 522 is disposed in the recess 3121 and is connected to the fixed hopper plate 312 via a mounting seat; the telescopic member 523 is fixed to the fixed hopper plate 312, and the telescopic end of the telescopic member 523 is connected to the fixed hopper plate 312. When the guide wire slides down the surface of the fixed hopper plate 312, it is clamped into the blanking roller 521 and causes the blanking roller 521 to rotate. When the blanking roller 521 rotates, the telescopic member 523 is activated and the telescopic end extends, allowing the alignment drive roller 522 to drive the guide wire to move along the first direction.

[0075] Specifically, the blanking roller 521 can be gear-shaped, and a plurality of grooves can be spaced apart on the plate surface of the fixed warehouse plate 312 facing the warehouse plate, and a blanking roller 521 is rotatably connected in each groove. The multiple blanking rollers 521 are rotatably connected through the same rotating shaft, and the teeth of the blanking roller 521 protrude from the plate surface of the fixed warehouse plate 312. When the guide wire slides along the plate surface of the fixed warehouse plate 312, it can be stuck in the teeth of the blanking roller 521. The weight of the guide wire and the gravity of continuous sliding are superimposed, which can drive the blanking roller 521 to rotate. On the one hand, it cushions the sliding guide wire, and on the other hand, it facilitates the guide wire to slide horizontally; a plurality of recesses 3121 can be opened at the bottom of the fixed warehouse plate 312, and the mounting seat is set in the recesses 3121. A plurality of alignment drive rollers 522 are rotatably connected to the mounting seat, and the axis of the alignment drive roller 522 is parallel to the plate surface of the fixed warehouse plate 312; the telescopic member 523 can drive the mounting seat to move toward or away from the plate surface of the fixed warehouse plate 312. For example, when the guide wire slips, it falls into the teeth of the blanking roller 521, and the guide wire drives the blanking roller 521 to rotate. During the rotation of the blanking roller 521, the telescopic part 523 can be started by triggering the switch. At this time, the telescopic end of the telescopic part 523 is extended, so that the end face of the positioning drive roller 522 protrudes from the fixed warehouse plate 312, and the guide wire will be stuck between the positioning drive roller 522 and the inclined surface of the movable warehouse plate 313. Then the positioning drive roller 522 rotates, which can drive the guide wire to move in the first direction, so that the end of the guide wire can be aligned. Each time the guide wire falls, the end of the guide wire can be aligned, and the ends of the guide wire can be kept in the same position before falling, which can not only improve the operation and alignment efficiency, but also help to keep the ends of multiple guide wires aligned.

[0076] For example, a rotary potentiometer may be mounted on the rotating shaft of the plurality of blanking rollers 521. When the guide wire drives the blanking rollers 521 to rotate, the rotary potentiometer can trigger the activation switch of the telescopic member 523, thereby extending the telescopic member 523. Of course, the triggering method of the telescopic member 523 switch can also be achieved by providing a magnetic switch, a cam microswitch, or other methods on the rotating shaft. The present invention does not specifically limit this. Those skilled in the art can select a specific method based on actual factors such as the quality and length of the guide wire, and the damping of the rotation of the blanking rollers 521.

[0077] In addition, the diameter of the alignment driving roller 522 can gradually increase in the direction away from the blanking roller 521, so that the guide wire can be smoothly clamped between the alignment driving roller 522 and the inclined surface.

[0078] Furthermore, the alignment assembly 52 also includes a limit block 524 and a touch switch provided on the limit block 524. When the alignment drive roller 522 drives the guide wire to move along the first direction, the end of the guide wire contacts the limit block 524 and triggers the touch switch. When the touch switch is triggered, the telescopic member 523 is started and the telescopic end contracts.

[0079] Specifically, a limit block 524 can be provided on both the leading and trailing ends of the guide wire, and the limit blocks 524 are located in the feed hole. When the guide wire is clamped between the alignment drive roller 522 and the inclined surface, the alignment drive roller 522 rotates to drive the guide wire in a first direction. When the end of the guide wire contacts the limit block 524, a touch switch on the limit block 524 is triggered. After the touch switch is triggered, the telescopic member 523 is activated. At this time, the telescopic end of the telescopic member 523 contracts, thereby driving the alignment drive roller 522 to contract, allowing the telescopic member 523 to be triggered again when the next guide wire slides down, and then the guide wire can fall out of the feed hole. The touch switch can be a light switch.

[0080] It should be noted that after each guide wire falls from the discharge hole, the telescopic member 523 can drive the positioning drive roller 522 to reset, and the next guide wire can trigger the telescopic member 523 again by driving the discharge roller 521 to rotate, and make the end contact with the limit block 524 again; thereby, the ends of multiple guide wires can all contact with the limit block 524 and then fall into the conveying trough 21, so that the end positions of multiple guide wires remain consistent when they fall.

[0081] like Figure 3As shown, in one embodiment of the present invention, a delivery hole 11 is defined in a mounting base 1, with front and rear conveyor rails 22 and 23 located on either side of the delivery hole 11. A delivery mechanism 4 is disposed within the delivery hole 11 and further includes a sliding seat 41 and a delivery drive 42. The sliding seat 41 is movably connected to the mounting base 1 and positioned within the delivery hole 11. A delivery clamp 43 is disposed on the sliding seat 41. The delivery drive 42 is disposed below the mounting base 1 and is configured to drive the sliding seat 41 to reciprocate in a first direction.

[0082] Specifically, a delivery hole 11 is opened in the middle of the mounting base 1, and the sliding seat 41 can be set in the delivery hole 11. The delivery driving part 42 drives the sliding seat 41 to move in the delivery hole 11. After the delivery clamp 43 clamps the guide wire, the sliding seat 41 moves, thereby driving the guide wire to be delivered.

[0083] Exemplarily, both the front-end conveying rail 22 and the rear-end conveying rail 23 can be composed of multiple sections of sub-rails, and the sub-rails of the front-end conveying rail 22 and the sub-rails of the rear-end conveying rail 23 near the delivery hole 11 are slidably connected to the mounting base plate 1. Both the front-end conveying rail 22 and the rear-end conveying rail 23 are composed of multiple sections of sub-rails, and there may be a spacing between each section of the sub-rails, and the sub-rails located at both ends of the delivery hole 11 are slidably connected to the mounting base plate 1, and both ends of the sub-rails can be connected to a cylinder, which drives the two sections of the sub-rails to move in the first direction. The positions of the sub-rails at both ends are adaptively adjusted according to the length or falling position of the guide wire, so that when the guide wire just falls to the conveying rail 2, the head end and the tail end of the guide wire can be in the conveying groove 21, avoiding the head end of the guide wire from being suspended in the air, facilitating the delivery mechanism 4 to clamp the guide wire and move, and further keep the ends of the guide wire aligned.

[0084] In one embodiment of the present invention, the delivery clamp 43 includes a clamping seat 431 and a delivery roller 432. The clamping seat 431 is connected to the sliding seat 41, and two clamping seats 431 are symmetrically provided; the delivery roller 432 is rotatably connected to each of the two clamping seats 431, and the guide wire is clamped between the two delivery rollers 432.

[0085] Specifically, the two clamping seats 431 can move towards or away from each other under the drive of an electric push rod or a motor, so that the guide wire can be clamped by the delivery rollers 432 on both sides; in addition, the delivery rollers 432 on the two clamping seats 431 can rotate in opposite directions at the same speed at the same time under the drive of the motor, so as to further keep the ends of multiple guide wires aligned.

[0086] Furthermore, the opposite sides of the upper parts of the two clamping seats 431 are both inclined surfaces, and the distance between the two clamping seats 431 gradually decreases from the top to the middle, making it easier for the guide wire to enter between the two clamping seats 431.

[0087] In one embodiment of the present invention, the guide wire synchronous feeding device further includes a positioning mechanism 6, which is used to clamp and position the guide wires. In actual operation, the delivery mechanism 4 can sequentially drive each guide wire to move an appropriate distance, so that the end of the guide wire extends a certain distance from the conveyor rail 2. The positioning mechanism 6 then fixes the position of the guide wire so that it does not move during subsequent guide wire delivery. When multiple guide wires have reached the corresponding position, the positioning mechanism 6 releases the multiple guide wires, and the clamping and feeding mechanism simultaneously clamps the multiple guide wires and delivers them to the marking device.

[0088] For example, the positioning mechanism 6 may include a positioning seat, a clamping block sliding in the positioning seat, and a positioning cylinder connected to the positioning seat. The positioning seat is provided with a perforation through which the guide wire passes. The telescopic end of the positioning cylinder is connected to the clamping block to drive the clamping block to move radially along the perforation. Specifically, the perforation passes through the positioning seat, and a slot may be provided on the positioning seat. The bottom of the slot is flush with the wall of the perforation, and the clamping block is inserted into the slot. When the positioning cylinder is telescopic, it drives the clamping block to move radially along the perforation, thereby pressing the guide wire passing through the perforation and achieving positioning of the guide wire. At the same time, the diameter of the entrance of the perforation can gradually decrease inward to facilitate the entry of the end of the guide wire into the perforation.

[0089] An embodiment of the present invention further provides a feeding method, which uses the above-mentioned guide wire synchronous feeding device, and the feeding method includes the following steps:

[0090] S1. Use the discharge drive unit 32 to adjust the position of the silo assembly 31 so that the discharge hole is directly above one of the conveying troughs 21;

[0091] Specifically, before starting delivery, the width of the discharge hole can be adjusted by the hopper plate adjustment part 314 according to the diameter of the guide wire, so that the width of the discharge hole is greater than or equal to the diameter of the guide wire, so that the guide wire can smoothly fall into the conveying trough 21; at the same time, the hopper seat 311 is driven to move by the discharge drive part 32 to align the discharge hole with one of the conveying troughs 21; in addition, the position of the head end and the tail end of the guide wire when entering the conveying trough 21 is determined according to the length of the guide wire, and the front conveying rail 22 and the rear conveying rail 23 located at both ends of the delivery hole 11 are moved so that the head end or the tail end of the guide wire can be in the conveying trough 21.

[0092] S2. Place the guide wire into the feed assembly 51. The guide wire slides from the feed assembly 51 into the hopper assembly 31. After the alignment assembly 52 moves the ends of the multiple guide wires to the same position, the guide wire falls from the discharge hole into the conveying trough 21.

[0093] Specifically, the guide wire is placed into the discharge trough 511 by a robot or manually. The guide wire is limited by the limiting slide 512 and the feeding roller 514, and can slide out of the discharge port and fall onto the fixed warehouse plate 312. As the guide wire continues to slide, it drives the blanking roller 521 to rotate and activates the telescopic member 523. The alignment drive roller 522 drives the guide wire to move in the first direction, and the end of the guide wire abuts the limiting block 524. Then, the guide wire falls from the discharge hole into the conveying trough 21. There is no need to accurately locate the position of the guide wire during placement, which improves operational efficiency and reduces the burden on operators.

[0094] S3, the material bin assembly 31 is driven by the material discharge driving unit 32 to move in the second direction so that the material discharge holes are aligned with the remaining conveying troughs 21 in sequence, and S2 is repeated;

[0095] Specifically, the discharge driving unit 32 is used to align the discharge holes with the remaining conveying grooves 21 in sequence, and the guide wires are placed into the conveying grooves 21 during the alignment, so as to facilitate the subsequent delivery of multiple guide wires.

[0096] As described above, the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that the technical solutions described in the above embodiments can still be modified, or some of the technical features thereof can be replaced by equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
