Description

Technical Field

[0001] The present invention relates to the technical field of testing devices, and particularly to a guide wire performance detection device and a guide wire detection method. Background Art

[0002] After the production of the guide wire, it is also necessary to conduct spot checks and performance tests on the guide wire. There are various parameter indicators that affect the performance of the guide wire, such as friction force value, torque force value, and torque friction force value, etc. It is necessary to place the guide wire in different devices for testing. In this way, it is necessary to configure more testing devices, which increases the production cost. Moreover, the testing methods of the current testing devices are relatively simple. They can only tighten or twist the guide wire for testing and cannot simulate the internal environment of the human body, resulting in poor accuracy of the guide wire testing. Therefore, there is an urgent need for a guide wire detection device with richer functions and more accurate performance detection. Summary of the Invention

[0003] The purpose of the present invention is to provide a guide wire performance detection device and a guide wire detection method 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 of the present invention to solve its technical problems is as follows: A guide wire performance detection device, comprising: a rotating mechanism having a first wire clamp that can rotate along a horizontal axis; a straightening mechanism having a force tester that can move in a direction close to or away from the first wire clamp, and a second wire clamp is provided at the test end of the force tester; a pressing mechanism including a water tank, a base, a pressing plate, and a water supply joint. The water tank is located between the first wire clamp and the second wire clamp. The base is arranged in the water tank, a groove is provided on the top side of the base, the pressing plate is located above the base, the pressing plate can move downward close to the top side of the base or upward away from the base, the water supply joint is connected to the pressing plate, and a water outlet hole communicating with the water supply joint is provided on the bottom side of the pressing plate.

[0005] The technical solution has at least the following beneficial effects: The first wire clamp and the second wire clamp are used to clamp the end of the guide wire. The water supply joint can be connected to an external water supply device. When performance testing of the guide wire is required, the guide wire is placed on the base. One end of the guide wire can be clamped and fixed by the second wire clamp. Water at the required temperature, such as water close to body temperature, is input from the water supply joint, so that the water flows into the groove of the base from the water outlet hole. At this time, the water wets the surface of the guide wire, activating the hydrophilic coating on the surface of the guide wire, thereby simulating the wet environment of the guide wire in the human body. If the friction performance of the guide wire needs to be tested, at this time, the first wire clamp does not need to clamp the guide wire. The guide wire is pressed and positioned on the base by the pressing plate, and the force tester moves in a direction away from the base, pulling the guide wire taut. At this time, the force tester detects the pulling force on the guide wire, thereby testing the friction performance of the guide wire; if the torque performance of the guide wire needs to be tested, at this time, the first wire clamp clamps the other end of the guide wire, and then the first wire clamp rotates. The force tester measures the magnitude of the torque received by the guide wire, thereby testing the torque performance of the guide wire; if the torque friction performance of the guide wire needs to be tested, at this time, the first wire clamp clamps the other end of the guide wire, the pressing plate presses the guide wire and positions it on the base, and then the first wire clamp rotates. The force tester measures the magnitude of the torque received by the guide wire, thereby testing the torque friction performance of the guide wire. In this way, various parameter indicators of the guide wire can be measured in a simulated wet state of the guide wire, the overall use function is more abundant, and the accuracy of the measurement result of the guide wire is improved.

[0006] As a further improvement of the above technical solution, the pressing mechanism includes a fixing frame connected in the water tank, a lifting driving member connected to the fixing frame, the lifting driving member is drivingly connected to the pressing plate, and a pressure sensor is arranged on the pressing plate. The pressure sensor is used to detect the downward pressure of the pressing plate. The lifting driving member provides a driving force for the pressing plate to move in the up and down direction. When the guide wire needs to be pressed, the lifting driving member drives the pressing plate to move down until it abuts against the guide wire. At this time, the pressure sensor can detect the external force received by the pressing plate, so as to better control the pressure on the guide wire and improve the accuracy of the test on the guide wire. After the test on the guide wire is completed, the lifting driving member drives the pressing plate to move up and reset.

[0007] As a further improvement of the above technical solution, when the lifting drive member drives the pressing plate to abut against the base, the lifting drive member is configured to drive the pressing plate to move upward until the pressure value detected by the pressure sensor is 0, and then drive the pressing plate to move downward until the pressure sensor detects a preset pressure value. When the lifting drive member drives the pressing plate to abut against the base, the pressure value detected by the pressure sensor changes. At this time, the lifting drive member controls the pressing plate to move upward until the pressure value detected by the pressure sensor is 0, so that the pressing plate is in a state of approaching the guide wire, and then drives the pressing plate downward so that the pressing plate reaches the required downward pressure on the guide wire. In this way, the downward pressure of the pressing plate on the guide wire can be more accurately controlled, thereby meeting the performance test requirements for the guide wire.

[0008] As a further improvement of the above technical solution, a heater and a water pump are arranged in the water tank, the heater is used to heat the water in the water tank, and a water supply pipe is connected between the water pump and the water supply joint. The water tank is filled with water for wetting the guide wire, which is heated to a set temperature by the heater and then pumped to the water supply joint through the water supply pipe by the water pump, so that water flows from the water outlet into the groove, at which time the water supply to the groove can be continuously maintained, so that the water in the groove is full, so as to better wet the guide wire, and the water flowing out of the groove flows back into the water tank, so that water is circulated, which can reduce water waste and improve the wetting effect on the guide wire.

[0009] As a further improvement of the above technical solution, the rotating mechanism includes a motor and a three-jaw chuck, the motor is connected to the three-jaw chuck, the motor can drive the three-jaw chuck to rotate along the horizontal axis, and the three-jaw chuck clamps the first wire clamp. When it is necessary to clamp the end of the guide wire, the first wire clamp can be taken out first, and the end of the guide wire can be clamped and positioned by the first wire clamp, and then the first wire clamp can be installed in the three-jaw chuck and clamped and fixed, and then the motor provides a rotational driving force to the three-jaw chuck, and a torque is applied to the guide wire for performance testing.

[0010] As a further improvement of the above technical solution, the straightening mechanism includes a translational drive member, which drives and connects to the force tester, and the translational drive member can drive the force tester to approach or move away from the first wire clamp. The translational drive member can provide a driving force for the force tester to approach or move away from the first wire clamp. When the guide wire needs to be tested for performance, the translational drive member drives the force tester to move in a direction away from the first wire clamp, pulls the guide wire to a straight state, and then continues to move in a direction away from the first wire clamp to perform a performance test on the guide wire. After completion, the translational drive member drives the force tester to return to the direction close to the first wire clamp and reset.

[0011] As a further improvement of the above technical solution, a slide rail is slidably connected to the bottom side of the water tank, and the water tank can move and be locked between the first wire clamp and the second wire clamp. The water tank can slide on the slide rail, so as to adjust the position state of the water tank relative to the first wire clamp and the second wire clamp, which is convenient for performing performance tests on the guide wire at different positions. After completion, the water tank is locked on the slide rail.

[0013] This technical solution has at least the following beneficial effects: In this guide wire detection method, the friction performance of the guide wire is tested. At this time, the first wire clamp does not need to clamp the guide wire. The guide wire is guided to pass through the top side of the base, and one end of the guide wire is clamped and fixed by the second wire clamp. During the test, the guide wire is pressed and positioned on the base by the pressing plate, and the force tester moves away from the base to tighten the guide wire. At this time, the force tester measures the tensile force value of the guide wire, so as to test the friction performance of the guide wire.

[0026] Referring to Figure 1 and Figure 2 , a guide wire performance detection device, comprising a rotating mechanism, a straightening mechanism and a pressing mechanism. Among them, the rotating mechanism has a first wire clamp 110 that can rotate along a horizontal axis; the straightening mechanism has a force tester 210 that can move in a direction close to or away from the first wire clamp 110. A second wire clamp 220 is provided at the test end of the force tester 210. The force tester 210 is mainly used to measure tensile force and torsional force, and can be a torque sensor and a tensile force sensor, or a screw-type sensor; the pressing mechanism includes a water tank 310, a base 320, a pressing plate 330 and a water supply joint 340. The water tank 310 is located between the first wire clamp 110 and the second wire clamp 220. The base 320 is arranged in the water tank 310. A groove is provided on the top side of the base 320. The pressing plate 330 is located above the base 320. The pressing plate 330 can move downward close to the top side of the base 320 or upward away from the base 320. The water supply joint 340 is connected to the pressing plate 330. An outlet hole communicating with the water supply joint 340 is provided on the bottom side of the pressing plate 330.

[0027] As described above, the first wire clamp 110 and the second wire clamp 220 are used to clamp the end of the guide wire. The water supply joint 340 can be connected to an external water supply device. When performance testing of the guide wire is required, the guide wire is placed on the base 320. One end of the guide wire can be clamped and fixed by the second wire clamp 220. Water at the required temperature, such as water close to body temperature, is input from the water supply joint 340, so that the water flows into the groove of the base 320 from the water outlet holes. At this time, the water wets the surface of the guide wire, activating the hydrophilic coating on the surface of the guide wire, thereby simulating the wet environment of the guide wire in the human body. If the friction performance of the guide wire needs to be tested, at this time, the first wire clamp 110 does not need to clamp the guide wire. The pressure plate 330 presses the guide wire and positions it on the base 320, and the force tester 210 moves in a direction away from the base 320 to tension the guide wire. At this time, the force tester 210 detects the pulling force on the guide wire, thereby testing the friction performance of the guide wire; if the torque performance of the guide wire needs to be tested, at this time, the first wire clamp 110 clamps the other end of the guide wire, and then the first wire clamp 110 rotates. The force tester 210 tests the magnitude of the torque received by the guide wire, thereby testing the torque performance of the guide wire; if the torque friction performance of the guide wire needs to be tested, at this time, the first wire clamp 110 clamps the other end of the guide wire, the pressure plate 330 presses the guide wire and positions it on the base 320, and then the first wire clamp 110 is rotated. The force tester 210 tests the magnitude of the torque received by the guide wire, thereby testing the torque friction performance of the guide wire. In this way, various parameter indicators of the guide wire can be measured in a state where the guide wire is simulated to be wet, the overall use function is more abundant, and the accuracy of the measurement result of the guide wire is improved.

[0028] A driving source for driving the pressure plate 330 to move up and down is mainly formed in the pressing mechanism. In this embodiment, the pressing mechanism includes a fixing frame 350 connected in the water tank 310 and a lifting driving member 360 connected to the fixing frame 350. The lifting driving member 360 is drivingly connected to the pressure plate 330. The lifting driving member 360 can be a cylinder, a hydraulic cylinder or an electric screw cylinder, etc. A pressure sensor is arranged on the pressure plate 330. The pressure sensor is used to detect the downward pressure of the pressure plate 330. In practical applications, the pressure sensor can be arranged at the connection between the pressure plate 330 and the lifting driving member 360. At this time, the external force received by the pressure plate 330 can be completely transmitted to the pressure sensor. The lifting driving member 360 provides a driving force for the pressure plate 330 to move in the up and down direction. When the guide wire needs to be pressed, the lifting driving member 360 drives the pressure plate 330 to move down until it abuts against the guide wire. At this time, the pressure sensor can detect the external force received by the pressure plate 330, so as to better control the pressure on the guide wire and improve the accuracy of the test on the guide wire. After the test on the guide wire is completed, the lifting driving member 360 drives the pressure plate 330 to move up and reset.

[0029] To improve the effect of pressing and positioning the guide wire, the pressing plate 330 can be made of rubber material. Additionally, the base 320 itself can also be made of rubber material, or a rubber gasket is provided at the position around the groove on the top side of the base 320, thereby improving the stability of pressing and positioning the guide wire.

[0030] When the lifting drive member 360 drives the pressing plate 330 to move downward to the base 320, at this time, the pressing plate 330 can directly press and position the guide wire by driving the lifting drive member 360 according to the pressure value detected by the pressure sensor. In actual applications, in order to more accurately control the feed amount of the lifting drive member 360, when the pressing plate 330 approaches the guide wire, the control origin of the lifting drive member 360 can be repositioned to eliminate the cumulative stroke error. Specifically, when the lifting drive member 360 drives the pressing plate 330 to abut against the base 320, the lifting drive member 360 is configured to be able to drive the pressing plate 330 to move upward until the pressure value detected by the pressure sensor is 0, and then drive the pressing plate 330 to move downward until the pressure sensor detects a preset pressure value. When the lifting drive member 360 drives the pressing plate 330 to abut against the base 320, the pressure value detected by the pressure sensor changes. At this time, the lifting drive member 360 controls the pressing plate 330 to move upward until the pressure value detected by the pressure sensor is 0, so that the pressing plate 330 is in a state of approaching the guide wire, and then drives the pressing plate 330 to move downward, so that the pressing plate 330 exerts the required downward pressure on the guide wire. In this way, the downward pressure of the pressing plate 330 on the guide wire can be more accurately controlled, thereby meeting the performance test requirements of the guide wire.

[0031] In the above embodiment, the water supply pipe can be directly connected to an external water supply device. At this time, water can be added to the water tank 310 until it contacts the guide wire. In order to further improve the wetting effect on the guide wire, in this embodiment, a heater 370 and a water pump are provided in the water tank 310. The heater 370 is used to heat the water in the water tank 310, and a water supply pipe is connected between the water pump and the water supply joint 340. The water tank 310 is filled with water for wetting the guide wire. After being heated to the set temperature by the heater 370, the water is pumped by the water pump through the water supply pipe to the water supply joint 340, so that the water flows into the groove from the water outlet hole and is filled. At this time, the water supply to the groove can be continuously maintained, so that the water in the groove is in a full state, better wetting the guide wire. The water flowing out of the groove then flows back into the water tank 310. In this way, the water can be recycled, reducing water waste and improving the wetting effect on the guide wire.

[0032] A rotating driving source may be provided in the rotating mechanism to directly drive the first wire clamp 110 to rotate. In order to facilitate the replacement of the first wire clamp 110, in the present embodiment, the rotating mechanism includes a motor 120 and a three-jaw chuck 130. The motor 120 is connected to the three-jaw chuck 130 in a transmission manner. The motor 120 can drive the three-jaw chuck 130 to rotate along the axis in the horizontal direction, and the three-jaw chuck 130 clamps the first wire clamp 110. When it is necessary to clamp the end of the guide wire, the first wire clamp 110 can be taken out first, and after the first wire clamp 110 is used to clamp and position the end of the guide wire, the first wire clamp 110 is loaded into the three-jaw chuck 130 and clamped and fixed. Then, the motor 120 provides a rotational driving force to the three-jaw chuck 130, and a torque is applied to the guide wire for performance testing.

[0033] The first wire clamp 110 includes a clamp rod and a clamp cap. A channel is formed in the clamp rod for the guide wire to pass through. A plurality of slots are arranged around the channel at the end of the clamp rod, and the plurality of slots are respectively connected to the channel. The clamp cap is connected to the end of the clamp rod by a thread. A conical pressure section is arranged on the inner side of the clamp cap. When the clamp cap is tightened in the clamp rod, the pressure section presses against the outer position of the end of the clamp rod where the slot is arranged, and as the clamp cap is further tightened, the pressure of the pressure section on the end of the clamp rod gradually increases. The clamp rod is clamped and fixed by the three-jaw chuck 130. When the guide wire is clamped and positioned, the guide wire passes through the clamp cap and extends into the channel. The clamp cap is tightened on the clamp rod. At this time, the pressure of the pressure section on the end of the clamp rod gradually increases, so that the end of the clamp rod is elastically deformed toward the center of the channel, and the guide wire is clamped and positioned. Similarly, the second wire clamp 220 has the same structure as the first wire clamp 110.

[0034] As a specific embodiment of the straightening mechanism, the straightening mechanism includes a translation driver 230, the translation driver 230 drives and connects the force tester 210, the translation driver 230 can drive the force tester 210 to approach or move away from the first clamp 110, and the translation driver 230 can be a cylinder, an electric screw or a hydraulic cylinder. The translation driver 230 can provide a driving force for the force tester 210 to approach or move away from the first clamp 110. When the guide wire needs to be tested for performance, the translation driver 230 drives the force tester 210 to move in a direction away from the first clamp 110, pulls the guide wire to a straight state, and then continues to move in a direction away from the first clamp 110 to perform a performance test on the guide wire. After completion, the translation driver 230 drives the force tester 210 to return to the direction close to the first clamp 110 and reset.

[0035] In some embodiments, a slide rail 380 is slidably connected to the bottom side of the water tank 310. The water tank 310 can move and be locked between the first wire clamping device 110 and the second wire clamping device 220. In practical applications, a slider is provided at the bottom side position of the water tank 310. The slider is connected to the slide rail 380 in a mating manner. A locking screw can be passed through the slider, and the end of the locking screw is abutted against the slide rail 380, so as to lock the water tank 310 to the slide rail 380. When the locking screw leaves the slide rail 380, the water tank 310 can slide on the slide rail 380. The water tank 310 can slide on the slide rail 380, so as to adjust the position state of the water tank 310 relative to the first wire clamping device 110 and the second wire clamping device 220, which can facilitate the performance test of the guide wire at different positions. After completion, the water tank 310 is locked on the slide rail 380 again.

[0036] When detecting the guide wire, when the performance parameter indicators to be detected are different, the operation methods are also different. Therefore, one end of the guide wire is fixed in the second wire clamping device 220. According to the requirements of the performance detection of the guide wire, the guide wire is pressed by the pressing plate 330 and then pulled, or the other end of the guide wire is clamped and then rotated, or the other end of the guide wire is clamped, the pressing plate 330 presses the guide wire and then the guide wire is rotated.

[0037] As the first implementation manner of the guide wire detection method, using the above-mentioned guide wire performance detection device, includes but is not limited to the following steps: Step S110, the second wire clamping device 220 clamps one end of the guide wire and guides the guide wire to pass through the base 320. At this time, the guide wire extends along the direction away from the second wire clamping device 220 on the base 320, so that when the pressing plate 330 presses the guide wire, the guide wire is in a straightened state.

[0038] Step S120, water at a preset temperature is supplied to the water supply joint 340. The water enters the water tank 310 from the water outlet holes and wets the guide wire. The water supplied at the water supply joint 340 can be supplied from an external water supply device, or circulated from the water tank 310 to the water supply joint 340.

[0039] Step S130, the pressing plate 330 moves downward to press the guide wire against the base 320. The lifting driving member 360 provides a downward driving force for the pressing plate 330 to drive the pressing plate 330 to move downward onto the base 320. In actual tests, according to the requirements of the friction performance detection of the guide wire, the amount of downward movement of the pressing plate 330 driven by the lifting driving plate at this time can be controlled, so that the pressing plate 330 provides the required pressing force for the guide wire.

[0040] Step S140, the second wire clamp 220 moves away from the base 320, and the force tester 210 measures the tensile force value of the guide wire. As the second wire clamp 220 moves away from the base 320, the tensile force value measured by the force tester 210 for the guide wire also gradually increases in an upward trend until it reaches a peak value, at which point the tensile force peak value of the guide wire can be measured.

[0041] In this guide wire detection method, to test the frictional force performance of the guide wire, at this time, the first wire clamp 110 does not need to clamp the guide wire. The guide wire is fed through the top side of the base 320, and one end of the guide wire is clamped and fixed using the second wire clamp 220. During the test, the guide wire is pressed and positioned on the base 320 by the pressing plate 330, and the force tester 210 moves away from the base 320 to tighten the guide wire. At this time, the force tester 210 measures the tensile force value on the guide wire, thereby testing the frictional force performance of the guide wire.

[0042] As a second implementation manner of the guide wire detection method, using the above-mentioned guide wire performance detection device, it includes but is not limited to the following steps: Step S210, the first wire clamp 110 and the second wire clamp 220 respectively clamp both ends of the guide wire. When both ends of the guide wire are fixed and straightened by the first wire clamp 110 and the second wire clamp 220, the guide wire passes through the top side of the base 320.

[0043] Step S220, water at a preset temperature is supplied to the water supply joint 340. The water enters the water tank 310 from the water outlet holes and wets the guide wire. The water supplied at the water supply joint 340 can be supplied from an external water supply device, or can be circulated from the water tank 310 to the water supply joint 340.

[0044] Step S230, the first wire clamp 110 rotates, and the force tester 210 measures the torque value of the guide wire. The motor 120 provides a rotational driving force to the first wire clamp 110, and torque is provided from one end of the guide wire through the first wire clamp 110. At this time, the force tester 210 can measure the torque value received by the guide wire.

[0045] In this guide wire detection method, to test the torque performance of the guide wire, at this time, the first wire clamp 110 and the second wire clamp 220 respectively clamp both ends of the guide wire, and then the first wire clamp 110 rotates. The force tester 210 tests the torque value of the guide wire, thereby testing the torque performance of the guide wire.

[0046] As a third implementation manner of the guide wire detection method, using the above-mentioned guide wire performance detection device, it includes but is not limited to the following steps: Step S310, the first wire clamp 110 and the second wire clamp 220 clamp both ends of the wire respectively. After both ends of the wire are fixed and straightened by the first wire clamp 110 and the second wire clamp 220, the wire passes through the top side of the base 320.

[0047] Step S320, water at a preset temperature is supplied to the water supply joint 340. The water enters the water tank 310 from the water outlet holes and wets the wire. The water supplied at the water supply joint 340 can be supplied from an external water supply device, or can be circulated from the water tank 310 to the water supply joint 340.

[0048] Step S330, the pressing plate 330 moves downward to press the wire against the base 320. The lifting driving member 360 provides a downward driving force for the pressing plate 330 to drive the pressing plate 330 to move downward onto the base 320. In actual tests, according to the requirements for detecting the torque friction performance of the wire, the amount of downward movement of the pressing plate 330 driven by the lifting driving plate at this time can be controlled so that the pressing plate 330 provides the required pressing force for the wire.

[0049] Step S340, the first wire clamp 110 rotates, and the force tester 210 measures the torque friction value of the wire. The motor 120 provides a rotational driving force for the first wire clamp 110 to provide torque from one end of the wire through the first wire clamp 110. At this time, the force tester 210 can measure the torque friction value received by the wire.

[0050] In this wire detection method, the torque friction performance of the wire is tested. At this time, the first wire clamp 110 and the second wire clamp 220 clamp both ends of the wire respectively, the pressing plate 330 presses and positions the wire on the base 320, and then the first wire clamp 110 is rotated. The force tester 210 tests the torque friction of the wire, thereby testing the torque friction performance of the wire.

[0051] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the above embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of this application.
