Description

Technical Field

[0001] The present invention relates to the technical field of puncture needle grinding, and specifically to a puncture needle grinding device with finished product detection function and a processing method thereof. Background Art

[0002] Puncture needle grinding equipment plays a crucial role in the manufacturing of medical devices. Through high-precision grinding processes, it ensures that the tip of the puncture needle meets extremely high precision requirements, enabling precise control in terms of diameter, length, angle, curve trajectory, etc. The puncture grinding equipment grinds the surface of the puncture needle, improving the smoothness of the tip, reducing friction with tissues, and further reducing the pain of patients. At the same time, the equipment also features automated and intelligent production methods, significantly improving production efficiency, reducing production costs, and bringing a more efficient and economical production method to the medical device manufacturing industry.

[0003] However, there are still many deficiencies and defects in the current puncture needle grinding equipment. Most of the grinding equipment on the market has a low level of intelligence and can only grind a single group of puncture needles, resulting in low production efficiency. Although some equipment can grind multiple groups of puncture needles, the processing accuracy cannot be guaranteed, and the puncture needle grinding equipment on the market cannot detect the processed finished products, unable to ensure the yield rate of the finished puncture needles. Summary of the Invention

[0004] The purpose of the present invention is to provide a puncture needle grinding device with finished product detection function to solve the problems raised in the prior art.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A puncture needle grinding device with finished product detection function, including a support pedestal. A progressive component is installed on the support pedestal, an intelligent adjustment component is installed on the support pedestal, a grinding and detection component is installed at the top of the support pedestal, and a number of fixed detection components are slidably installed on the intelligent adjustment component. The fixed detection components are slidably connected to the progressive component; the progressive component includes a progressive motor and a progressive disk. The progressive motor is installed on the support pedestal, a progressive gear is installed on the output shaft of the progressive motor, the progressive disk is rotatably installed on the support pedestal, and the progressive gear is in meshing transmission with the progressive disk; a number of arc grooves and teeth are provided on the progressive disk. The progressive disk is slidably connected to the fixed detection components through the arc grooves, and the progressive disk is in meshing transmission with the progressive gear through the teeth. A control system is installed inside the support pedestal, and the control system is used to control the entire grinding device.

[0006] After the grinding angle of the puncture needle is adjusted, the control system activates the progressive motor. The progressive motor drives the progressive gear to rotate, the progressive gear drives the progressive disk to rotate, and the progressive disk drives the transmission column to rotate. Since the fixed frame is slidably installed in the sliding groove, the transmission column cannot drive the fixed frame to rotate. The fixed frame converts the rotation into sliding along the sliding groove. As the progressive disk rotates, the fixed frame drives the puncture needle to gradually approach the grinding roller.

[0007] The intelligent adjustment component includes a bottom tray and an adjustment motor. The bottom tray is installed on the support pedestal. An adjustment gear ring is rotatably installed at the bottom end of the bottom tray. The adjustment motor is installed on the support pedestal. An adjustment gear is installed on the output shaft of the adjustment motor. The adjustment gear meshes with the adjustment gear ring for transmission. An adjustment member is rotatably installed on the bottom tray. The adjustment member meshes with the adjustment gear ring for transmission. The fixed detection component is slidably installed on the adjustment member. A semi-circular groove is provided on the bottom tray; the adjustment gear ring is provided with internal teeth and external teeth. The adjustment gear ring meshes with the adjustment member through the internal teeth, and the adjustment gear ring meshes with the adjustment gear ring through the external teeth.

[0008] The adjustment member is provided with a sliding groove. The fixed detection component is slidably installed in the sliding groove. The adjustment member is provided with a tooth groove. The internal teeth mesh with the tooth groove for transmission. A sliding column is installed on the adjustment member. The sliding column is slidably connected to the semi-circular groove.

[0009] The fixed detection component includes a fixed frame. A detection hole is provided on the fixed frame. Fixed sliding rods are installed at both the bottom end and the top end of the fixed frame. A number of support rings are provided on the fixed frame. Holes are provided on the support rings. Bottom sliding holes are symmetrically provided at the bottom end of the fixed frame. A bottom rotating rod is installed at the bottom end of the fixed frame. A front support rod is installed on the fixed frame. A number of support grooves are provided on the front support rod. A transmission column is installed on the fixed frame. A bottom slider is provided at the bottom end of the fixed frame. The fixed frame is slidably installed on the sliding groove through the bottom slider.

[0010] The fixed detection component further includes a detector, a transmission component, a limit plate, and a clamping component. The detector is installed in the detection hole. The clamping component is installed on the fixed frame. The limit plate is slidably installed on the fixed sliding rod. A limit spring is installed between the limit plate and the fixed frame. A first spring is installed on the fixed frame. One end of the first spring is installed with a push head. A hole groove is provided in the center of the push head. The hole groove is used for fitting with the end of the puncture needle. The transmission component is rotatably installed on the bottom rotating rod. The transmission component is rotatably connected to the limit plate; the clamping component includes an electric telescopic rod. The output shaft of the electric telescopic rod penetrates through the fixed frame and is installed with a clamping block. The clamping block is slidably connected to the top end of the fixed frame. A transmission claw is installed at the bottom end of the clamping block. A transmission wheel is rotatably installed on the transmission claw.

[0011] The puncture needle is passed through the holes in the bracket and the support ring so that the end of the puncture needle is engaged with the hole groove at the center of the push head. The bracket lifts the front end of the puncture needle to prevent the front end of the puncture needle from being unstable due to being suspended in the air during grinding, and the support ring supports the rear end of the puncture needle. After the puncture needle is installed, the control system turns on the electric telescopic rod, and the output shaft of the electric telescopic rod drives the two clamping blocks to move closer together. The clamping blocks move closer together and clamp the puncture needle. When the clamping blocks are close to each other, they drive the transmission wheels on the bottom transmission claws to move closer together. When the transmission wheels are close, the slopes on both sides of the transmission slider are adjusted. When the cam is pressed against the locking plate, the locking plate is moved upwards, and the locking plate is engaged with the locking cam, and the locking cam is engaged with the locking cam, and the locking cam is engaged with the locking cam.

[0012] Under normal conditions, the upper and lower centers of the holes on the transmission column and the adjusting part are aligned, the control system turns on the adjusting motor, the adjusting motor output shaft drives the adjusting gear to rotate, the adjusting gear drives the adjusting gear ring to rotate, the adjusting gear ring drives the adjusting part to deflect, the adjusting part drives the entire fixed detection assembly to deflect around the center line of the transmission column, the puncture needle deflects along with the fixed detection assembly, and after the deflection, the angle between the puncture needle and the grinding roller is deflected. During grinding, due to the different angles between the puncture needle and the grinding roller, the angle of the needle tip bevel after grinding is also different. The control system deflects the adjusting part at a corresponding angle according to the processing requirements of the puncture needle tip angle, thereby achieving the purpose of multi-angle processing of the puncture needle tip.

[0013] A sliding hole is provided on the limit plate, and a sliding ring is provided on the limit plate. The limit plate is slidably installed on the fixed sliding rod through the sliding ring. A limiting rotating rod is provided at the bottom end of the limit plate, and the limit plate is rotatably connected to the transmission assembly through the limiting rotating rod; the transmission assembly includes a transmission slider and a transmission rotating rod. The transmission slider is rotatably connected to one end of the transmission rotating rod, and the transmission rotating rod is rotatably installed on the bottom rotating rod. The transmission slider is symmetrically provided with slopes, and the other end of the transmission rotating rod is rotatably connected to the limit plate through the limiting rotating rod. Sliding rods are symmetrically provided at the bottom end of the transmission slider, and the sliding rods are slidably installed in the bottom sliding hole.

[0014] The detector includes a detection shell, which is installed in the detection hole. A piezoelectric element is installed in the detection shell. An inner slider is slidably installed in the detection shell. An outer slider is slidably installed in the detection shell. A compression chamber is formed between the inner slider and the outer slider, and the compression chamber is filled with a compression medium.

[0015] The control system controls the clamping assembly to reset, the clamping blocks separate, and the clamping of the puncture needle is released, allowing the puncture needle to slide within the holes of the bracket and the support ring. Meanwhile, the transmission wheel follows the separation of the clamping blocks and no longer exerts extrusion on the transmission slider. The upward lifting force of the transmission assembly on the limit plate disappears. Under the action of the elastic force of the limit spring, the limit plate slides downward and resets, and the sliding hole aligns with the push head. The control system restarts the progressive assembly, and the progressive assembly drives the fixed frame to move. The fixed frame drives the puncture needle to approach the detection body and gradually penetrate into the detection body. When the needle tip enters the detection body, the detection body exerts damping on the needle tip. The needle tip experiences resistance and generates relative displacement with the fixed frame. The end of the puncture needle pushes the push head to slide. The push head overcomes the elastic force of the first spring and slides through the sliding hole. The push head pushes the outer slider, and the outer slider slides within the detection housing under extrusion. The sliding of the outer slider squeezes the compression medium in the compression chamber, increasing the pressure in the compression chamber. The inner slider slides under pressure and squeezes the piezoelectric element. The piezoelectric element generates charges under pressure, and the charges are transmitted to the control system through wires. When the puncture needle moves a preset distance, the progressive assembly is turned off. At this time, under the action of the pulling force of the first spring, the push head continues to squeeze the end of the puncture needle, and the puncture needle continues to slowly penetrate into the detection body. As the puncture needle further enters the detection body, the extrusion force of the push head on the outer slider gradually attenuates. The attenuation of the extrusion force causes the extrusion force on the piezoelectric element to decrease, resulting in a gradual weakening of the electrical signal received by the control system until it reaches zero. The sharper the puncture needle, the shorter the time it takes to penetrate the detection body, and the shorter the time for the corresponding electrical signal to attenuate to zero. The control system determines the sharpness of the puncture needle tip based on data such as the time of electrical signal attenuation and the initial speed at the time of attenuation, thereby realizing the finished product detection of the puncture needle. When it is unqualified, the previous operation is repeated to perform secondary grinding on the puncture needle, thereby realizing the secondary polishing of the unqualified puncture needle and improving the qualified rate of intelligent production of the puncture needle.

[0016] The grinding and detection assembly includes a cylinder, which is installed on the support pedestal. A driving motor is installed on the output shaft of the cylinder. A detection body is installed on the output shaft of the driving motor. A connecting piece is installed at the bottom end of the detection body, and a grinding roller is installed at the bottom end of the connecting piece. The detection body is made of a flexible material. The flexible material used for the detection body is a flexible damping material, which exerts damping on the needle tip when the needle tip penetrates the detection body.

[0017] The control system turns on the driving motor. The output shaft of the driving motor drives the grinding roller to rotate through the connecting piece. The grinding roller synchronously grinds multiple groups of puncture needles. During grinding, the setting of the bracket keeps the front end of the puncture needle stable and prevents excessive deformation and shaking due to contact with the grinding roller, improving the stability of grinding. After grinding, the control system controls the progressive assembly and the fixed detection assembly to reset, and then controls the intelligent adjustment assembly to reset the deflected adjustment part to make the puncture needle point to the center line of the detection body. The control system turns on the cylinder, and the output shaft of the cylinder drives the driving motor to descend. The driving motor drives the detection body to descend through the connecting piece until the detection body aligns with the puncture needle.

[0018] A processing method of a puncture needle with a finished product detection function includes the following steps:

[0019] S1. Fix the puncture needle;

[0020] S2. Adjust the angle of the puncture needle;

[0021] S3. Grind the puncture needle;

[0022] S4. Detect the quality of the finished product.

[0023] Step S1 includes the following specific steps:

[0024] S101. Place the puncture needle on the fixed detection component, and use the fixed detection component to clamp and fix the puncture needle;

[0025] Step S2 includes the following specific steps:

[0026] S201. Use the intelligent adjustment component to adjust the angle of the fixed detection component, and the fixed detection component drives the puncture needle to deflect at an angle;

[0027] Step S3 includes the following specific steps:

[0028] S301. Use the progressive component to drive the fixed detection component to move on the intelligent adjustment component, the fixed detection component drives the puncture needle to approach the grinding detection component, and use the grinding detection component to grind the puncture needle;

[0029] Step S4 includes the following specific steps:

[0030] S401. After grinding, reset the fixed detection component. Then, use the fixed detection component and the grinding detection component to cooperate with each other to detect the finished puncture needle. If the detection result is qualified, the grinding and finished product detection of the puncture needle are completed; if the detection result is unqualified, repeat the previous steps, and use the grinding detection component to perform secondary grinding on the unqualified puncture needle until the detection is qualified.

[0031] Compared with the prior art, the beneficial effects of the present invention are:

[0032] 1. Use the progressive disk to synchronously drive multiple groups of puncture needles to approach the grinding roller, ensuring the consistency when the puncture needles are fed, and guaranteeing the grinding accuracy; the control system can drive the fixed detection component to deflect at a corresponding angle through the adjustment component according to the processing requirements of the tip angle of the puncture needle, so as to achieve the purpose of multi-angle intelligent adjustment and processing of the tip of the puncture needle.

[0033] 2. The bracket is arranged to keep the front end of the puncture needle stable, preventing excessive deformation and vibration when contacting the grinding roller, thus improving the stability of grinding. A cylinder is used to switch the grinding or detection state of the grinding and detection assembly.

[0034] 3. The progressive component drives the puncture needle into the detection body, converting the resistance received by the needle tip into the sliding of the push head. Then, the push head triggers the detector, which converts the thrust of the push head into a change in pressure in the compression chamber, and further converts the change in pressure into the extrusion of the piezoelectric element, causing the piezoelectric element to generate an electrical signal. The control system determines the sharpness of the puncture needle tip based on data such as the decay time of the electrical signal and the initial velocity at the time of decay, thereby realizing the intelligent detection of the finished puncture needle. When it is unqualified, the puncture needle is ground for the second time, thus realizing the secondary processing of the unqualified puncture needle and improving the qualified product rate of the intelligent production of the puncture needle.

[0035] 4. A set of puncture needles can be installed on each fixing bracket. The arrangement of multiple fixing brackets enables the grinding of multiple sets of puncture needles simultaneously, increasing the processing quantity of the puncture needles and improving the production efficiency. The front bracket and the support ring are used to support the front and rear ends of the puncture needle, and the bracket holds up the front end of the puncture needle to prevent it from being unstable due to suspension during grinding. The clamping component is used to fixedly clamp multiple puncture needles. During the clamping process, the movement of the clamping block drives the transmission wheel to squeeze the transmission component, causing the transmission component to drive the limit plate to move upward to achieve the purpose of limiting the push head.

[0067] The working principle of the present invention is as follows: the puncture needle is passed through the holes in the bracket 416 and the supporting ring 414, so that the end of the puncture needle is engaged with the hole groove at the center of the push head 47, the bracket 416 lifts the front end of the puncture needle to prevent the front end of the puncture needle from being unstable due to being suspended in the air during grinding, and the supporting ring 414 supports the rear end of the puncture needle; after the puncture needle is installed, the control system turns on the electric telescopic rod 442, and the output shaft of the electric telescopic rod 442 drives the two clamping blocks 441 to move closer, the clamping blocks 441 move closer and clamp the puncture needle, and when the clamping blocks 441 are close to each other, they respectively drive the transmission wheels 444 on the bottom transmission claws 443 to move closer to each other, and when the transmission wheels 444 are close, the slopes on both sides of the transmission slider 431 are adjusted. The transmission bevel is squeezed and slides downward along the sliding rod 432 after being squeezed, and the transmission slider 431 drives the end of the transmission rod connected to it to move downward, so that the transmission rotating rod 433 rotates around the bottom rotating rod 419, and the end of the bottom rotating rod 419 connected to the limiting plate 45 is lifted upward, driving the limiting plate 45 to slide upward along the fixed sliding rod 413. In the initial state, the sliding hole 451 corresponds to the position of the push head 47, and the push head 47 can move and pass through the sliding hole 451. As the limiting plate 45 slides upward, the sliding hole 451 slides away from its original position, and the position of the push head 47 and the sliding hole 451 are offset. The limiting plate 45 resists the push head 47, so that the push head 47 cannot move backward, thereby realizing the limitation of the push head 47.

[0068] Under normal conditions, the transmission column 411 is aligned with the upper and lower centers of the holes on the adjustment member 55, the control system turns on the adjustment motor 52, the output shaft of the adjustment motor 52 drives the adjustment gear 53 to rotate, the adjustment gear 53 drives the adjustment gear ring 54 to rotate, the adjustment gear ring 54 drives the adjustment member 55 to deflect, the adjustment member 55 drives the entire fixed detection assembly 4 to deflect around the center line of the transmission column 411, the puncture needle deflects along with the fixed detection assembly 4, after the deflection, the angle between the puncture needle and the grinding roller 25 is deflected, during grinding, due to the different angles between the puncture needle and the grinding roller 25, the angle of the needle tip bevel after grinding is also different, the control system deflects the adjustment member 55 at a corresponding angle according to the processing requirements of the puncture needle tip angle, thereby achieving the purpose of multi-angle processing of the puncture needle tip.

[0069] After the grinding angle of the puncture needle is adjusted, the control system starts the progressive motor 31, the progressive motor drives the progressive gear 32 to rotate, the progressive gear 32 drives the progressive disk 33 to rotate, and the progressive disk 33 drives the transmission column 411 to rotate. Since the fixed frame 41 is slidably installed in the sliding groove 551, the transmission column 411 cannot drive the fixed frame 41 to rotate, and the fixed frame 41 converts the rotation into sliding along the sliding groove 551. As the progressive disk 33 rotates, the fixed frame 41 drives the puncture needle to gradually approach the grinding roller 25.

[0070] The control system activates the drive motor 22. The output shaft of the drive motor 22 drives the grinding roller 25 to rotate through the connecting member 24. The grinding roller 25 polishes multiple groups of puncture needles synchronously. During the polishing process, the setting of the bracket 416 enables the front end of the puncture needle to be stable and not to undergo excessive deformation and vibration due to contact with the grinding roller 25, improving the stability of grinding. After grinding, the control system controls the progressive component 3 and the fixed detection component 4 to reset, and then controls the intelligent adjustment component 5 to reset the deflected adjustment member 55, so that the puncture needle points to the center line of the detection body 23. The control system activates the cylinder 21, and the output shaft of the cylinder 21 drives the drive motor 22 to descend. The drive motor 22 drives the detection body 23 to descend through the connecting member 24 until the detection body 23 is aligned with the puncture needle.

[0071] The control system controls the clamping component 44 to reset, and the clamping block 441 separates, disconnecting the clamping of the puncture needle, enabling the puncture needle to slide within the holes of the bracket 416 and the retaining ring 414. At the same time, the transmission wheel 444 follows the separation of the clamping block 441 and no longer exerts pressure on the transmission slider 431. The upward lifting force of the transmission component 43 on the limiting plate 45 disappears. Under the elastic force of the limiting spring 48, the limiting plate 45 slides downward and resets, and the sliding hole 451 is aligned with the push head 47. The control system restarts the progressive component 3, and the progressive component 3 drives the fixed frame 41 to move. The fixed frame 41 drives the puncture needle to approach the detection body 23 and gradually penetrate into the detection body 23. When the needle tip enters the detection body 23, the detection body 23 exerts damping on the needle tip, and the needle tip is subjected to resistance and generates a relative displacement with the fixed frame 41. The end of the puncture needle pushes the push head 47 to slide. The push head 47 slides against the elastic force of the first spring 46 and passes through the sliding hole 451. The push head 47 pushes the outer slider 422. The outer slider 422 slides under extrusion within the detection housing 421. The sliding of the outer slider 422 causes the compressed medium in the compression chamber 423 to be extruded, increasing the pressure in the compression chamber 423. The inner slider 424 slides under pressure and squeezes the piezoelectric element 425. The piezoelectric element 425 generates charges under pressure, and the charges are transmitted to the control system through the wire. When the puncture needle moves a preset distance, the progressive component 3 is turned off. At this time, under the pulling force of the first spring 46, the push head 47 continues to squeeze the end of the puncture needle, and the puncture needle continues to slowly penetrate into the detection body 23. As the puncture needle further enters the detection body 23, the extrusion force of the push head 47 on the outer slider 422 gradually decays. The decay of the extrusion force causes the extrusion force on the piezoelectric element 425 to decrease, resulting in a gradual weakening of the electrical signal received by the control system until it reaches zero. The sharper the puncture needle, the shorter the time it takes to penetrate the detection body 23, and the shorter the time for the corresponding electrical signal to decay to zero. The control system determines the sharpness of the puncture needle tip based on data such as the decay time of the electrical signal and the initial speed at the time of decay, thereby realizing the finished product detection of the puncture needle. When it is unqualified, the previous operation is repeated to perform secondary grinding on the puncture needle, thereby realizing the secondary polishing of the unqualified puncture needle and improving the qualified rate of intelligent production of the puncture needle.
