Description

Technical Field

[0001] The present invention relates to the technical field of PEEK tube production, in particular to a full-automatic medical PEEK tube diameter-changing stretching device. Background Art

[0002] Medical PEEK tubing is a material used specifically in the medical field and is made of polyetheretherketone (PEEK). It has advantages such as high temperature tolerance, high mechanical strength, and good biocompatibility, making it widely used in medical devices. PEEK tubing variable diameter stretching is a method of processing PEEK tubing. By stretching PEEK tubing, its diameter and wall thickness can be thinned or thickened, thereby changing the size of the tubing. This technology can customize the inner diameter, outer diameter, and wall thickness of the tubing to specific needs. The fully automatic medical PEEK variable diameter stretching device is a device specifically designed to achieve diameter changes in medical PEEK tubing. The device typically consists of a stretching machine, a heating system, a mold, and a control system.

[0003] During the operation of the fully automatic medical PEEK tube variable diameter stretching device, non-destructive testing methods such as ultrasonic testing and radiographic testing can be used to inspect the pipeline to identify possible defects or problems. This ensures that the pipeline quality meets requirements before stretching and avoids potential problems in subsequent processes. Generally speaking, fixed flaw detection equipment can detect any problems before the stretching device, allowing timely measures to ensure pipeline quality and safety.

[0004] However, the above flaw detection method has certain problems. The accuracy of flaw detection during the movement of PEEK pipelines is questionable. At the same time, if a defect is detected in the pipeline during transportation, the wound control system will control the equipment to stop conveying the pipeline. At this time, if there is enough PEEK tube in front of the defect location that meets the set processing parameters, it will cause a waste of resources. At this time, the fully automatic equipment will be in a shutdown state and the pipeline will need to be replaced, which will affect the processing efficiency.

[0005] At the same time, the dust on the surface of the PEEK tubing when it is stretched will also affect the processing accuracy. After stretching to a uniform specification and discharging, it needs to be disinfected and sterilized. Personnel are required to transfer the workpiece to other disinfection and sterilization equipment, which will increase the workload of personnel and affect efficiency. If the equipment is used for direct transportation, the cost will increase. Radiation sterilization may not be able to effectively sterilize the inner ring of the PEEK tubing, and there is a potential risk of microbial infection, which is more serious in the medical field.

[0019] Compared with the prior art, the advantages of the present invention are:

[0020] (1) The present invention arranges an industrial camera that can rotate around the PEEK pipeline between the guide rail clamp and the loading platform to capture images of the PEEK pipeline to check whether there are defective wounds in the PEEK pipeline, thereby preventing quality problems from occurring after the damaged PEEK pipeline is subjected to diameter-changing stretching. After the PEEK pipeline is clamped by the guide rail clamp, the PEEK pipeline remains stable and motionless. At this time, the electric guide rail drives the industrial camera to move horizontally to perform flaw detection on the stationary PEEK pipeline, which can improve accuracy. At the same time, it detects the part that needs to be cut off later. When a problem occurs, only the part of the PEEK pipeline on the left side of the guide rail clamp needs to be removed, which will not affect the stretching of the part of the PEEK pipeline after the initial cut-off, thereby improving the processing efficiency of the machine body. Compared with the previous flaw detection method, it can also avoid the shutdown of the entire equipment after the wound defect is detected, and the removal of the entire PEEK pipeline, resulting in the cost waste caused by the removal of part of the PEEK pipeline that is sufficient for the processing setting parameters. With the setting of the distance measuring sensor, the distance between the wound position and the cut-off point can be understood, so that the user can handle it in time.

[0021] (2) The present invention simultaneously sets the synchronization ring on the left side of the annular plate, and generates a heat flow that blows toward the surface of the PEEK pipeline when the PEEK pipeline penetrates. The heat flow can preheat the surface of the PEEK pipeline to a certain extent, and the heat flow can also blow off the attached dust. The exhaust seat and the air intake seat are correspondingly set. The air flow generated by the exhaust seat is blown out and contacts the PEEK pipeline, and then continues to move. The part affected by the suction force flows back to the interior of the synchronization ring through the air intake seat, thereby preheating and removing dust from the surface of the PEEK pipeline. The filter assembly can ensure that dust is prevented from spilling out in the rotating synchronization ring, and avoid the spilled dust from filling the interior of the synchronization ring and affecting the air intake, or even multiple groups of impacts causing damage or blockage to the filter assembly.

[0022] (3) The present invention can limit the stretched PEEK pipeline on the discharge conveyor belt through the limiting mechanism inside the limiting cylinder, thereby driving the PEEK pipeline to flip, and cooperate with the sterilization lamp on the top to complete the sterilization and disinfection of the outer ring of the PEEK pipeline. While the limiting cylinder limits the PEEK pipeline, heat flow is filled into the PEEK pipeline. Most of the heat flow has power and rushes into the PEEK pipeline. As the heat flow continues to be filled, the heat flow moves to the left until it is discharged from the PEEK pipeline. The heat flow can complete the disinfection operation inside the PEEK pipeline, thereby ensuring the sterility of the pipeline, eliminating potential microbial infection, and meeting medical requirements.

The limit plate 2205 is located outside the slide groove 2203. The control system 2 can control the parameters of the electromagnetic ring 2202. Two sterilization lamps 233 are fixedly installed on the inner wall of the annular plate 8. The two sterilization lamps 233 are respectively located on the front and back of the industrial camera 10. A nano pressure sensor 30 is installed on the limit plate 2205, and the nano pressure sensor 30 is connected to the control system 2 signal.

[0041] The body 1 in this application is a fully automatic medical PEEK reducer tube stretching device, which can automatically adjust parameters according to the raw material pipeline and required specifications. At the same time, the electronic components proposed in the application document are also connected to the control system 2, and the control system 2 can issue instructions or transmit signals to the control system 2.

[0042] When the PEEK pipeline needs to be stretched with a variable diameter, the user sets the parameters through the control system 2. After receiving the instructions, the components in the body 1 are adjusted to the corresponding positions. For example, after the initial pipeline cut-off length is set, the electric guide rail 6 cooperates with the parameter instructions to drive the support seat 7 to move back and forth horizontally, and the moving distance is the same as the set value.

[0043] The control system 2 controls the driving motor 11 to be powered on, and the driving motor 11 drives the gear fixedly connected to it to rotate synchronously, so that the gear ring 9 starts to rotate synchronously, and one side of the gears on both sides is always engaged with the gear ring 9, so that the gear ring 9 completes the cycle rotation, and the internal sterilization lamp 2 33 and the industrial camera 10 rotate accordingly, and the auxiliary mechanism 16 attached to the annular plate 8 rotates accordingly. The control system 2 will simultaneously control the induced draft fan 1604 and the heating wire 1605 to be powered on, and the airflow is sucked into the synchronizer ring 1601 through the air inlet seat 1603, and then moves along the inner cavity of the synchronizer ring 1601, penetrates the filter component 1606, and is heated by the heating wire 1605 to rise in temperature before being discharged through the exhaust seat 1602.

[0044] Initially, the new PEEK pipeline enters the loading table 3 and slowly penetrates the synchronization ring 1601 and the annular plate 8 before entering the guide rail clamp 4 for clamping. During the movement, the airflow is discharged through the exhaust seat 1602 and sprayed onto the surface of the PEEK pipeline. As the synchronization ring 1601 rotates, the airflow blows to different positions of the PEEK pipeline, and the heat flow can preheat the surface of the PEEK pipeline to a certain extent. The heat flow can also blow off the attached dust. The exhaust seat 1602 is corresponding to the air intake seat 1603. The airflow generated by the exhaust seat 1602 blows out and contacts the PEEK pipeline, then continues to move and the part affected by suction flows back to the inside of the synchronization ring 1601 through the air intake seat 1603, thereby preheating and removing dust from the surface of the PEEK pipeline.

[0045] At the same time, the rotating sterilization lamp 2 33 can perform preliminary sterilization on the surface of the PEEK pipeline. The industrial camera 10 revolves around the PEEK pipeline to collect images of its surface, and then collects the values ​​into the control system 2 to achieve uniform flaw detection on the surface of the PEEK pipeline. If there is a defective wound on the surface of the PEEK pipeline, the control system 2 will stop the pipeline transportation. At the same time, the processor 15 controls the buzzer 14 to operate and generate a buzzer, prompting the user for timely processing to prevent affecting the quality of the entire batch of PEEK reducers. At the same time, when the support seat 7 moves, the distance sensor 12 will measure the distance between the distance measuring plate 13 in real time. When there is a defective wound, the support seat 7 remains stable and the support seat 7 is at the defective part of the PEEK pipeline. At this time, the distance measuring sensor 12 transmits the value to the control system 2, and the control system 2 can analyze the distance between the defective part of the PEEK pipeline and the cut-off part.

[0046] During the air intake process of the synchronizer ring 1601, whether it is the dust in the air flow or the dust falling off the PEEK pipeline entering the interior of the synchronizer ring 1601, it will be blocked by the collecting filter cartridge 162. The air flow enters the interior of the collecting filter cartridge 162 through the through slot 163 on one side, and the dust cannot penetrate the collecting filter cartridge 162. During the rotation of the synchronizer ring 1601, the gravity block 164 at the bottom of the collecting filter cartridge 162 makes the collecting filter cartridge 162 always in the initial vertical state, and the through slot 163 on the side away from the induced draft fan 1604 is always blocked. Moreover, since the collecting filter cartridge 162 always maintains a vertical state, the dust in the air flow will not be discharged after entering the collecting filter cartridge 162, and can be subsequently processed by pulling out the mounting base 161.

[0047] Then the guide rail clamp 4 is released to allow the pipeline to move into the processing assembly 34. The moving distance is a fixed length and is set and controlled by the control system 2. After the guide rail clamp 4 completes the clamping of the initial end of the PEEK pipeline, the cylinder 3405 inside the processing assembly 34 drives the cutter 3406 to move upward, and at this time the electric clamp 3403 on the left moves to the left on the transverse guide rail 3402 to the right side of the cutter 3406, and then clamps the pipeline. At this time, the fixed-length portion of the pipeline is on the right side of the left electric clamp 3403, and the cutter 3406 After moving up to complete the cutting of the pipeline, it is reset. At this time, the cut PEEK tube part is in an independent state. The clamping electric clamp 3403 transports the pipeline to the right. The pipeline passes through the heating plate 3404 until the other end is clamped by the electric clamp 3403 on the right. The heating plate 3404 softens the PEEK pipeline. The electric clamps 3403 on both sides move away from each other to deform the PEEK pipeline, thereby completing the diameter-changing stretching of the PEEK pipeline. After forming, the PEEK pipeline is transported to the discharge conveyor belt 5 by the loading robot 3407.

[0048] During the above processing, the part on the left side of the guide rail clamp 4 is not inspected and pre-processed. At this time, the electric guide rail 6 drives the support seat 7 to move horizontally to inspect and pre-process the PEEK pipeline. If an appearance defect is detected in this part, an alarm will also be issued, and the user can remove the PEEK pipeline for replacement or cutting. At this time, the body 1 is stretching the previously cut PEEK pipeline, thereby improving the processing efficiency of the body 1. Similarly, compared with the previous situation where the flaw detection equipment performs flaw detection during the movement of the PEEK pipeline and controls the equipment to stop transportation when a problem occurs, costs can be reduced and processing efficiency can be improved.

[0049] During the operation of the discharge conveyor belt 5, since it takes a certain amount of time for the machine body 1 to process the PEEK pipeline, the discharge conveyor belt 5 is in intermittent motion, and the motion interval time can be adjusted according to the parameters set in the control system 2. When the PEEK pipeline on the discharge conveyor belt 5 moves to the left side of the movable groove 20, the push rod 27 follows the operation, and the push rod 27 drives the reciprocating plate 28 to move to the left, and the limiting cylinder 21 then passes through the movable groove 20 to the left, so that one end of part of the PEEK pipeline is inside the limiting cylinder 21, and the electromagnetic ring 2202 then works to change the direction of current, so that the electromagnetic ring 2202 generates the same magnetic field as the magnetic plate 2204. The magnetic plate 2204 is affected by the magnetic field and moves inside the slide groove 2203, and the limiting plate 2205 then moves to contact the PEEK pipeline to limit it, and the nano pressure sensor 30 triggers the control limiting mechanism 22 to stop.

[0050] And the external heat flow pipe 19 begins to enter the heat flow, and the servo motor 25 is energized to drive the driving gear 26 fixed to it to rotate synchronously, and the driven gear 24 rotates accordingly and drives the limiting cylinder 21 to rotate. One end of the PEEK pipeline is inside the limiting cylinder 21, so the PEEK pipeline rotates accordingly until the cycle rotation is completed. The sterilization lamp 29 at the top sterilizes and disinfects the surface of the PEEK pipeline evenly and comprehensively, and the heat flow will enter the limiting cylinder 21 through the conveying box 18 and the air pipe 23. Most of the heat flow has power to rush into the inside of the PEEK pipeline. As the heat flow continues to be charged, the heat flow moves to the left until it is discharged from the PEEK pipeline. The heat flow can complete the disinfection operation inside the PEEK pipeline.

[0051] Then, before the discharge conveyor belt 5 works again, the electromagnetic ring 2202 pulls the magnetic plate 2204 to reset, so that the limit plate 2205 is separated from the PEEK pipeline, and the push rod 27 drives the reciprocating plate 28 to move right so that the limit cylinder 21 enters the movable groove 20. The sterilized PEEK pipeline can continue to be conveyed until the subsequent PEEK pipeline moves to the left side of the limit cylinder 21, thereby completing the fully automatic variable diameter stretching for the medical PEEK pipeline.

[0052] In actual use, the limiting mechanism 22 can be set to clamp the rotating part of the PEEK pipeline and then release it. The servo motor 25 drives the limiting cylinder 21 to rotate a certain angle and then re-clamp it, so that the contact area between the limiting plate 2205 and the PEEK pipeline is exposed to complete more comprehensive disinfection and sterilization.

[0053] In the present invention, an industrial camera 10 that can rotate around the PEEK pipeline is set between the guide rail clamp 4 and the loading platform 3 to capture images of the PEEK pipeline to check whether there are defects in the PEEK pipeline, so as to prevent the damaged PEEK pipeline from having quality problems after being stretched. After the PEEK pipeline is clamped by the guide rail clamp 4, the PEEK pipeline remains stable and motionless. At this time, the electric guide rail 6 drives the industrial camera 10 to move horizontally to detect the static PEEK pipeline, which can improve accuracy and at the same time detect the parts that need to be cut off later. The inspection is performed separately. When a problem occurs, it is only necessary to remove the part of the PEEK pipeline on the left side of the guide rail clamp 4, which will not affect the stretching of the part of the PEEK pipeline after the initial cut-off, thereby improving the processing efficiency of the machine body 1. Compared with the previous flaw detection method, it can also avoid the overall equipment shutdown after the wound defect is detected, and the removal of the entire PEEK pipeline, which leads to the cost waste caused by the removal of part of the PEEK pipeline that is sufficient for the processing setting parameters. In conjunction with the setting of the distance measuring sensor 12, the distance between the wound position and the cut-off point can be understood, so that the user can handle it in time.

[0054] At the same time, by synchronously setting the synchronization ring 1601 on the left side of the annular plate 8, a heat flow is generated and blown toward the surface of the PEEK pipeline when the PEEK pipeline penetrates, and the heat flow can preheat the surface of the PEEK pipeline to a certain extent, and the heat flow can also blow off the attached dust. The exhaust seat 1602 is correspondingly set to the air intake seat 1603. The airflow generated by the exhaust seat 1602 is blown out and contacts the PEEK pipeline, and then continues to move. The part affected by the suction force flows back to the inside of the synchronization ring 1601 through the air intake seat 1603, thereby preheating and removing dust from the surface of the PEEK pipeline. The filter component 1606 can ensure that dust is prevented from spilling out in the rotating synchronization ring 1601, to avoid the spilled dust filling the inside of the synchronization ring 1601 and affecting the air intake, or even multiple groups of impacts causing damage or blockage to the filter component 1606.

[0055] The limiting mechanism 22 inside the limiting cylinder 21 can limit the stretched PEEK pipeline on the discharge conveyor belt 5, thereby driving the PEEK pipeline to flip, and cooperating with the sterilization lamp 29 on the top to complete the sterilization and disinfection of the outer ring of the PEEK pipeline. While the limiting cylinder 21 limits the PEEK pipeline, heat flow is filled into the PEEK pipeline. Most of the heat flow has power and rushes into the PEEK pipeline. As the heat flow continues to be filled, the heat flow moves to the left until it is discharged from the PEEK pipeline. The heat flow can complete the disinfection operation inside the PEEK pipeline, thereby ensuring the sterile state of the pipeline, eliminating potential microbial infection, and meeting medical requirements.

[0056] See also Figure 6 , wherein: a double-lip shaft seal 31 is installed on the delivery box 18, and a sliding seal is performed between the air delivery pipe 23 and the double-lip shaft seal 31.

[0057] In the present invention, the provision of the double-lip shaft seal 31 can improve the airtightness between the gas delivery pipe 23 and the delivery box 18, and prevent the heat flow from escaping through the gap.

[0058] See also Figure 6-8 , wherein: the outer ring of the limiting cylinder 21 is provided with two guide grooves 32 , and the driven gear 24 is slidably connected to the inner wall of the guide groove 32 .

[0059] In the present invention, the guide groove 32 can limit the limiting cylinder 21 so that the limiting cylinder 21 rotates when the driven gear 24 rotates, but the limiting cylinder 21 does not affect the driven gear 24 when it moves horizontally.

Any person skilled in the art who, within the technical scope disclosed by the present invention, makes equivalent substitutions or modifications based on the technical solutions and improved concepts of the present invention shall be covered by the scope of protection of the present invention.
