Abstract
Description
Technical Field
[0001] This utility model relates to a guide wire production equipment, and more particularly to a guide wire dispensing machine. Background Technology
[0002] Medical guidewires are used to assist medical devices in passing through narrow or hard-to-reach areas. They consist of a core wire, a radiopaque spring fitted at the end of the core wire, and a sleeve fitted over both the core wire and the radiopaque spring. During production, adhesive is first applied to the end of the core wire, then the radiopaque spring is fitted over the end of the core wire and secured with adhesive. Next, adhesive is applied to the core wire, and the sleeve is fitted over the core wire for bonding and fixation. Currently, the entire production and assembly process of guidewires relies heavily on manual operation, resulting in low overall efficiency and difficulty in controlling production quality. Therefore, there is an urgent need for equipment that can improve the efficiency of guidewire production and assembly. Utility Model Content
[0003] The purpose of this utility model is to provide a wire guide dispensing machine to solve one or more technical problems existing in the prior art, and at least provide a beneficial option or create conditions.
[0004] The solution to the technical problem of this utility model is:
[0005] A wire guide dispensing machine includes: a positioning mechanism comprising a first fixture and a second fixture located behind the first fixture, the first fixture and the second fixture being movable in a front-rear direction respectively; a front glue groove and a rear glue groove being provided at intervals along the front-rear direction on the top side of the first fixture; a first limiting groove being provided on the top side of the first fixture at a position between the front glue groove and the rear glue groove; and a second limiting groove being provided on the top side of the second fixture at a position corresponding to the first limiting groove; a pressing mechanism having a pressure plate that can move downward toward or upward away from the second fixture; and a dispensing mechanism having a dispensing gun that can move downward toward or upward away from the first fixture.
[0006] This technical solution has at least the following beneficial effects: Before assembly, the sleeve used for assembling the guide wire is placed in the first limiting groove, and the two ends of the first limiting groove are used to limit the two ends of the sleeve. The core wire used for assembling the guide wire is placed in the second limiting groove, so that the front end of the core wire passes through the sleeve and over the front glue groove. The developing spring used for assembling the guide wire is sleeved on the front end of the guide wire that exits the sleeve, and the developing spring and the guide wire are placed together on the top side of the first fixture in front of the front glue groove. At this time, the rear end of the developing spring is suspended above the front glue groove, completing the loading of the guide wire, sleeve and developing spring. Then the first fixture and the second fixture move forward together, so that the developing spring moves to below the glue gun. The glue gun moves down and glue is applied to the rear end of the developing spring to bond the developing spring and the core wire. The glue overflowing during glue application can drip into the front glue groove. After the glue between the developing spring and the core wire has cured, the pressing mechanism... The inner pressure plate moves downwards towards the second fixture, pressing the core wire tightly into the second limiting groove. Then, the first fixture moves forward, using the limiting position of the second limiting groove end on the sleeve to move the sleeve forward, so that the sleeve is fitted outside the developing spring and extends forward beyond the front end of the core wire. At this point, the part of the core wire that needs to be bonded to the rear end of the sleeve is exposed above the rear adhesive groove. The dispensing gun moves downwards to dispense adhesive onto the core wire located above the rear adhesive groove. Then, the first fixture moves backwards, using the limiting position of the second limiting groove end on the sleeve to move the sleeve backwards, so that the position of the adhesive on the core wire reaches the rear end of the sleeve. At this point, the front end of the sleeve is also flush with the developing spring. After the adhesive cures, the assembly of the guide wire is completed. In this way, the dispensing and alignment of the developing spring, core wire, and sleeve during the assembly process are realized automatically by the machine, reducing manual operation and greatly improving the efficiency and quality of guide wire production.
[0007] As a further improvement to the above technical solution, the positioning mechanism includes a positioning translation drive, a tray, a guide rail, and a slide. The positioning translation drive is connected to the tray and can drive the tray to move back and forth. The first fixture is connected to the top side of the tray. The slide is slidably connected to the guide rail and can slide along the guide rail in the back and forth direction. The second fixture is connected to the top side of the slide. The rear side of the first fixture and the front side of the second fixture are magnetically connected. The positioning and translation drive provides a driving force to the tray to move in the front-to-back direction, thereby driving the first fixture to move back and forth. The second fixture is magnetically connected to the first fixture and can move along with the first fixture, thus ensuring that the core wire and the sleeve can be moved forward together. When the curing of the developing spring and the core wire is completed and the sleeve needs to be moved forward, the pressure plate presses down on the second fixture, pressing the guide wire downward. At this time, the slide is pressed against the guide rail, and the positioning and translation drive can drive the first fixture to move forward, so that the first fixture and the second fixture are separated from each other. By moving the sleeve back and forth, the relative position between the sleeve and the core wire can be adjusted. This simplifies the driving structure of the first and second fixtures, reduces production costs and energy consumption, and cleverly utilizes the magnetic connection between the first and second fixtures to achieve synchronous movement of the core wire and the sleeve, improving the quality of guide wire production and assembly.
[0008] As a further improvement to the above technical solution, a third limiting groove is provided on the top side of the first fixture at a position in front of the front glue groove, and the third limiting groove is connected to the front glue groove. The third limiting groove can be used to limit the horizontal position of the developing spring and to limit the position of the front end of the developing spring. In this way, the developing spring can be quickly positioned when placing it, improving the feeding efficiency.
[0009] As a further improvement to the above technical solution, the front and rear ends of the first limiting groove are respectively connected to the front glue groove and the rear glue groove. A front baffle is connected to the rear side of the front glue groove. The top side of the front baffle protrudes from the first limiting groove and is located below the top surface of the first fixture. A rear baffle is connected to the front side of the rear glue groove. The top side of the rear baffle protrudes from the first limiting groove and is located below the top surface of the second fixture. The first limiting groove extends from the top side of the first fixture to the front and rear rubber grooves. At this time, the front baffle on the rear side of the front rubber groove and the rear baffle on the front side of the rear rubber groove protrude from the front and rear ends of the first limiting groove, respectively, and abut against the bottom position of the sleeve end, thereby limiting the front and rear ends of the sleeve and preventing the sleeve from coming out of the first limiting groove. The core wire can pass through the top position of the front and rear baffles, which supports the core wire. In this way, the front and rear baffles block and limit the bottom position of the sleeve end without hindering the core wire from passing directly in the front and rear direction. This is conducive to the straight conveying of the core wire in the front and rear direction and improves the smoothness and stability of the sleeve relative to the core wire in the front and rear direction.
[0010] As a further improvement to the above technical solution, this utility model also includes a light curing lamp, which is located in front of the dispensing gun, and the first fixture can be moved to directly below the light curing lamp. After dispensing is completed at the bonding positions of the developing spring and the core wire, and at the bonding positions of the sleeve and the core wire, the first fixture can be moved forward to directly below the light curing lamp to increase the curing speed of the adhesive, thereby improving the overall dispensing efficiency.
[0011] As a further improvement to the above technical solution, this utility model also includes a light-blocking plate, which is vertically disposed between the dispensing gun and the UV curing lamp. The bottom side of the light-blocking plate has a clearance opening for avoiding the first fixture. The worker is positioned behind the positioning mechanism to replenish material. When it is necessary to cure the bonded and positioned guide wire, the first and second fixtures move forward, passing through the clearance opening on the bottom side of the light-blocking plate, and then move to below the UV curing lamp. At this time, UV curing is performed using the UV curing lamp, and the light-blocking plate effectively reduces the rearward illumination of the UV curing lamp, improving production safety.
[0012] As a further improvement to the above technical solution, the pressure plate is made of an elastic material. When the elastic pressure plate presses the guide wire tightly into the first limiting groove, it can improve the stability of pressing the guide wire and prevent the guide wire from deviating.
[0013] As a further improvement to the above technical solution, the pressing mechanism includes a pressing base, a pressing translation drive, and a pressing lifting drive. The pressing translation drive is connected to the pressing base, and the pressing lifting drive is connected to the pressing translation drive. The pressing translation drive can drive the pressing lifting drive to move left and right. The pressure plate is connected to the pressing lifting drive, and the pressing lifting drive can drive the pressure plate to move up and down. The pressing translation drive and the pressing lifting drive can respectively provide driving force to the pressure plate to move in the left-right and up-down directions. When it is necessary to press the guide wire, the pressing translation drive can drive the pressure plate to move horizontally above the first fixture, and then the pressing lifting drive provides power to drive the pressure plate to move downward to press the guide wire onto the first fixture. After the assembly of the guide wire is completed, the pressing lifting drive and the pressing translation drive drive the pressure plate to return to its original position.
[0014] As a further improvement to the above technical solution, the dispensing mechanism includes a dispensing base, a dispensing translation drive, and a dispensing lifting drive. The dispensing translation drive is connected to the dispensing base, and the dispensing lifting drive is connected to the dispensing translation drive. The dispensing translation drive can drive the dispensing lifting drive to move left and right. The dispensing gun is connected to the dispensing lifting drive, and the dispensing lifting drive can drive the dispensing gun to move up and down. The dispensing translation drive and the dispensing lifting drive can respectively provide driving force for the dispensing gun to move in the left-right and up-down directions. When it is necessary to press the guide wire, the dispensing translation drive can drive the dispensing gun to move horizontally above the first fixture, and then the dispensing lifting drive provides power to drive the dispensing gun to move down close to the guide wire bonding position for dispensing operation. When multiple guide wires are arranged side by side in the left-right direction, the dispensing translation drive can also drive the dispensing gun to move horizontally to dispense glue to multiple guide wires respectively. After completion, the dispensing lifting drive and the dispensing translation drive drive the dispensing gun to return to the reset position.
[0015] As a further improvement to the above technical solution, at least two positioning mechanisms are arranged along the left-right direction. During operation, one positioning mechanism feeds the guide wire, which is then assembled by the dispensing mechanism, while the other positioning mechanism can perform loading and unloading. This better coordinates the production cycle, reduces downtime, and further improves production efficiency. Attached Figure Description

[0029] Reference Figure 1A guide wire dispensing machine includes a positioning mechanism 100, a pressing mechanism 200, and a dispensing mechanism 300. The positioning mechanism 100 includes a first fixture 110 and a second fixture 120 located behind the first fixture 110. The first fixture 110 and the second fixture 120 are movable in a front-rear direction. A front adhesive groove 111 and a rear adhesive groove 112 are spaced apart on the top side of the first fixture 110 in the front-rear direction. A first limiting groove 113 is provided on the top side of the first fixture 110 at a position between the front adhesive groove 111 and the rear adhesive groove 112. The top side of the second fixture 120 corresponds to the first... The position of the limiting groove 113 is provided with a second limiting groove 121. In practical applications, one sleeve 530 is placed and positioned in one first limiting groove 113. In order to improve production efficiency, multiple first limiting grooves 113 can be provided in the left and right direction. Multiple sleeves 530 can be placed and positioned in multiple first limiting grooves 113 at the same time. Correspondingly, multiple second limiting grooves 121 are also provided on the top side of the second fixture 120. The pressing mechanism 200 has a pressure plate 210 that can move downward toward or upward away from the second fixture 120. The dispensing mechanism 300 has a dispensing gun 310 that can move downward toward or upward away from the first fixture 110.
[0030] As described above, before assembly, the sleeve 530 used for assembling the guidewire is placed in the first limiting groove 113, and the two ends of the first limiting groove 113 limit the two ends of the sleeve 530. The core wire 510 used for assembling the guidewire is placed in the second limiting groove 121, so that the front end of the core wire 510 passes through the sleeve 530 and over the front adhesive groove 111. The developing spring 520 used for assembling the guidewire is sleeved on the front end of the guidewire that exits the sleeve 530, and the developing spring is then applied. The spring 520, along with the guide wire, rests on the top side of the first fixture 110 in front of the front glue tank 111. At this time, the rear end of the developing spring 520 is suspended above the front glue tank 111, completing the loading of the guide wire, sleeve 530, and developing spring 520. Then, the first fixture 110 and the second fixture 120 move forward together, causing the developing spring 520 to move below the dispensing gun 310. The dispensing gun 310 moves downward, dispensing glue onto the rear end of the developing spring 520. Figure 7As shown, mark a to indicate the dispensing position. The developing spring 520 and the core wire 510 are bonded together. Excess adhesive during dispensing drips into the front adhesive groove 111. After the adhesive between the developing spring 520 and the core wire 510 cures, the pressure plate 210 in the pressing mechanism 200 moves downwards towards the second fixture 120, pressing the core wire 510 tightly into the second limiting groove 121. Then, the first fixture 110 moves forward. At this time, the second limiting groove 121 limits the sleeve 530, causing the sleeve 530 to move forward, so that the sleeve 530 is fitted onto the outside of the developing spring 520 and extends forward beyond the front end of the core wire 510. At this point, the portion of the core wire 510 that needs to be bonded to the rear end of the sleeve 530 is exposed. Above the glue tank 112, the glue gun 310 moves down to apply glue to the core wire 510 located above the glue tank 112. Mark b is the glue application position. Then, the first fixture 110 moves backward. At this time, the sleeve 530 is limited by the end of the second limiting groove 121, which drives the sleeve 530 to move backward, so that the glue application position on the core wire 510 reaches the rear end of the sleeve 530. At this time, the front end of the sleeve 530 is also flush with the developing spring 520. After the glue cures, the assembly of the guide wire is completed. In this way, the glue application and alignment of the developing spring 520, core wire 510 and sleeve 530 during the mutual assembly process are realized by mechanical automation, reducing manual operation and greatly improving the efficiency and quality of guide wire production.
[0031] In practical applications, the positioning mechanism 100, the pressing mechanism 200 and the dispensing mechanism 300 are respectively mounted on the frame, and the frame provides support and fixation for the whole.
[0032] In the positioning mechanism 100, two independent drive sources can be provided to drive the first fixture 110 and the second fixture 120 respectively. To reduce energy consumption and improve the synchronization of the movement of the core wire 510 and the sleeve, in this embodiment, as follows... Figure 2As shown, the positioning mechanism 100 includes a positioning translation drive 130, a support plate 140, a guide rail 150, and a slide 160. The positioning translation drive 130 is connected to the support plate 140 and can drive the support plate 140 to move back and forth. The positioning translation drive 130 can be an electric lead screw, thereby driving the first fixture 110 to move precisely. The first fixture 110 is connected to the top side of the support plate 140. The slide 160 is slidably connected to the guide rail 150 and can slide along the guide rail 150 in the back-and-forth direction. The second fixture 120 is connected to the top side of the slide 160. The rear side of the first fixture 110 is connected to the support plate 140. The front of the second fixture 120 is magnetically connected. In practical applications, the positioning and translation drive 130 and the guide rail 150 are respectively connected to the frame. The positioning and translation drive 130 can be installed on one side of the bottom of the tray 140 to provide driving force for the tray 140 to move back and forth. A movable seat is installed on the other side of the bottom of the tray 140. A slide rail is installed on the frame at the position corresponding to the movable seat. The movable seat is slidably connected to the slide rail. The slide 160 is located between the positioning and translation drive 130 and the movable seat. At this time, the second fixture 120 can also abut against the tray 140 to improve the stability of the second fixture 120. A clearance space is provided at the position of the movable seat corresponding to the tray 140 to avoid the movement of the slide 160.
[0033] In the positioning mechanism 100 employing a single drive source, the positioning translation drive 130 provides a driving force to the tray 140 to move in the front-to-back direction, thereby driving the first fixture 110 to move back and forth. The second fixture 120 is magnetically connected to the first fixture 110 and can move along with the first fixture 110, thus ensuring that the core wire 510 and the sleeve 530 can be moved forward together. When the curing of the developing spring 520 and the core wire 510 is completed and the sleeve 530 needs to be moved forward, the pressure plate 210 presses down onto the second fixture 120, pressing the guide wire downward. At this time, the slide 160 is pressed down. Tightly mounted on the guide rail 150, the positioning translation drive 130 can drive the first fixture 110 to move forward, so that the first fixture 110 and the second fixture 120 are separated from each other. By moving the sleeve 530 back and forth, the relative position between the sleeve 530 and the core wire 510 can be adjusted. This simplifies the driving structure of the first fixture 110 and the second fixture 120, reduces production costs and energy consumption, and cleverly utilizes the magnetic connection of the first fixture 110 and the second fixture 120 to achieve synchronous transfer of the core wire 510 and the sleeve 530, thereby improving the quality of guide wire production and assembly.
[0034] In the above embodiment, the developing spring 520, which is inserted into the end of the core wire 510, is only placed on the top side of the first fixture 110. However, to improve the stability of the developing spring 520's placement, in this embodiment, as... Figure 3As shown, a third limiting groove 114 is provided on the top side of the first fixture 110 at a position in front of the front glue tank 111, and the third limiting groove 114 is connected to the front glue tank 111. The third limiting groove 114 can be used to limit the horizontal position of the developing spring 520 and to limit the front end position of the developing spring 520. In this way, when placing the developing spring 520, it can be quickly placed and positioned, improving the loading efficiency.
[0035] In the above embodiment, when the first limiting groove 113 is opened on the top side of the first fixture 110, its front and rear ends may not be connected to the front glue groove 111 and the rear glue groove 112. In this case, the first limiting groove 113 needs to be set to a deeper depth to limit the sleeve 530, which may easily affect the straightness of the core wire 510 transfer. Therefore, in this embodiment, if... Figure 3 and Figure 4 As shown, the front and rear ends of the first limiting groove 113 are respectively connected to the front adhesive groove 111 and the rear adhesive groove 112. The rear side of the front adhesive groove 111 is connected to a front baffle 115. The top side of the front baffle 115 protrudes from the first limiting groove 113 and is located below the top surface of the first fixture 110. The front side of the rear adhesive groove 112 is connected to a rear baffle 116. The top side of the rear baffle 116 protrudes from the first limiting groove 113 and is located below the top surface of the second fixture 120. The first limiting groove 113 extends from the top side of the first fixture 110 to the front rubber groove 111 and the rear rubber groove 112. At this time, the front baffle 115 on the rear side of the front rubber groove 111 and the rear baffle 116 on the front side of the rear rubber groove 112 protrude from the front and rear ends of the first limiting groove 113 respectively, abutting against the bottom position of the end of the sleeve 530, thereby limiting the front and rear ends of the sleeve 530 and preventing the sleeve 530 from coming out of the first limiting groove 113. The core wire 510 can pass through the top position of the front baffle 115 and the rear baffle 116, which plays a supporting role for the core wire 510. In this way, the front baffle 115 and the rear baffle 116 block and limit the bottom position of the end of the sleeve 530 without hindering the core wire 510 from passing directly in the front and rear direction. This is conducive to the straight conveying of the core wire 510 in the front and rear direction and improves the smoothness and stability of the sleeve 530 relative to the core wire 510 in the front and rear direction.
[0036] After the guide wire is dispensing, the dispensing position can be allowed to cure naturally. To improve the curing efficiency of the adhesive, this invention also includes a light curing lamp in this embodiment. The light curing lamp is located in front of the dispensing gun 310, and the first fixture 110 can be moved directly below the light curing lamp. In practical applications, multiple light curing lamps can be arranged in the left-right direction to increase the illumination coverage. After dispensing is completed at the bonding positions of the developing spring 520 and the core wire 510, and at the bonding positions of the sleeve 530 and the core wire 510, the first fixture 110 can be moved forward to directly below the light curing lamp to increase the curing speed of the adhesive and thus improve the overall dispensing efficiency.
[0037] This utility model also includes a light-blocking plate 400, which is vertically disposed between the dispensing gun 310 and the UV curing lamp. The bottom side of the light-blocking plate 400 has a clearance opening 410 to allow the first fixture 110 to pass. In practical applications, the frame is equipped with door panels in front of and on both sides of the dispensing head. These door panels can surround and protect the dispensing mechanism 300 and the pressing mechanism 200, and further prevent the UV curing lamp from shining outwards. The worker is positioned behind the positioning mechanism 100 to replenish material. When it is necessary to cure the bonded and positioned guide wire, the first fixture 110 and the second fixture 120 move forward, passing through the clearance opening 410 on the bottom side of the light-blocking plate 400, and then move to below the UV curing lamp. At this time, UV curing is performed using the UV curing lamp, and the light-blocking plate 400 effectively reduces the rearward illumination of the UV curing lamp, improving production safety.
[0038] The pressure plate 210 can be made of a relatively hard material, such as metal or plastic. However, in order to improve the effect of pressing and positioning the guide wire, in this embodiment, the pressure plate 210 is made of an elastic material, such as rubber. When the elastic pressure plate 210 presses the guide wire tightly against the first limiting groove 113, it can improve the stability of pressing the guide wire and prevent the guide wire from deviating.
[0039] The pressing mechanism 200 may only have a drive source to move the pressure plate 210 downwards. However, to improve the flexibility of the pressing mechanism 200, especially when there are multiple positioning mechanisms 100, a single pressure plate 210 can be used to switch between different positioning mechanisms 100. Therefore, the pressing mechanism 200 may also include a drive source to move the pressure plate 210 horizontally. Specifically, for example... Figure 5As shown, the pressing mechanism 200 includes a pressing base 220, a pressing translation drive 230, and a pressing lifting drive 240. The pressing translation drive 230 is connected to the pressing base 220, and the pressing lifting drive 240 is connected to the pressing translation drive 230. The pressing translation drive 230 can drive the pressing lifting drive 240 to move left and right. The pressure plate 210 is connected to the pressing lifting drive 240, and the pressing lifting drive 240 can drive the pressure plate 210 to move up and down. The pressing translation drive 230 and the pressing lifting drive 240 are mainly used to provide driving force for reciprocating movement in a straight line. They have various structural forms, such as cylinders, electric lead screws, or hydraulic cylinders. The downward translation drive 230 and the downward lifting drive 240 can respectively provide driving force to the pressure plate 210 in the left-right and up-down directions. When it is necessary to press the guide wire, the downward translation drive 230 can drive the pressure plate 210 to move horizontally above the first fixture 110. Then, the downward lifting drive 240 provides power to drive the pressure plate 210 to move downward to press the guide wire onto the first fixture 110. After the assembly of the guide wire is completed, the downward lifting drive 240 and the downward translation drive 230 drive the pressure plate 210 to return to the reset position.
[0040] The dispensing mechanism 300 may only have a drive source to move the dispensing gun 310 downwards. However, to improve the flexibility of the dispensing mechanism 300, especially when there are multiple guide wires in each positioning mechanism 100, or when there are multiple positioning mechanisms 100, a single dispensing gun 310 can be used to switch between different positioning mechanisms 100. Therefore, the dispensing mechanism 300 may also include a drive source to move the dispensing gun 310 horizontally. Specifically, for example... Figure 6As shown, the dispensing mechanism 300 includes a dispensing base 320, a dispensing translation drive 330, and a dispensing lifting drive 340. The dispensing translation drive 330 is connected to the dispensing base 320, and the dispensing lifting drive 340 is connected to the dispensing translation drive 330. The dispensing translation drive 330 can drive the dispensing lifting drive 340 to move left and right. The dispensing gun 310 is connected to the dispensing lifting drive 340, and the dispensing lifting drive 340 can drive the dispensing gun 310 to move up and down. In practical applications, multiple dispensing guns 310 can be arranged at intervals along the left and right direction. The dispensing translation drive 330 and the dispensing lifting drive 340 are mainly used to provide driving force for reciprocating movement in a straight line direction. Their structural forms are various, such as cylinders, electric lead screws, or hydraulic cylinders. The dispensing translation drive 330 and the dispensing lifting drive 340 can respectively provide driving force for the dispensing gun 310 to move in the left-right and up-down directions. When it is necessary to press the guide wire, the dispensing translation drive 330 can drive the dispensing gun 310 to move above the first fixture 110. Then, the dispensing lifting drive 340 provides power to drive the dispensing gun 310 to move down close to the guide wire bonding position to perform the dispensing operation. When multiple guide wires are arranged side by side in the left-right direction, the dispensing translation drive 330 can also drive the dispensing gun 310 to move in a translational manner to dispense glue to multiple guide wires respectively. After completion, the dispensing lifting drive 340 and the dispensing translation drive 330 drive the dispensing gun 310 to return to the reset position.
[0041] There may be only one positioning mechanism 100. However, when one positioning mechanism 100 is loading or unloading, the entire machine needs to be stopped. Therefore, to increase the overall working capacity, in this embodiment, at least two positioning mechanisms 100 are arranged in the left-right direction. During operation, one positioning mechanism 100 loads guide wires, which are then glued and assembled by the dispensing mechanism 300, while the other positioning mechanism 100 can perform loading and unloading. This better coordinates the production cycle, reduces downtime, and further improves production efficiency.
[0042] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the embodiments described. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present invention. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
