At present, there are many kinds of medical catheter winding equipment, but the core part, i.e. winding turntable, is similar. This kind of winding turntable can wind medical catheter around the support rod, and then separate the wound medical catheter from the support rod, so that the mechanical hand can take away the wound medical catheter for the next process.

[0046] As shown in Figures 1 to 6 , the present embodiment provides a catheter winding device, comprising a workbench 100, a pipe supply mechanism 200, a winding mechanism 300, a pipe clamping assembly 400, a pipe winding clamping assembly 500, a moving assembly 600, a support 700, wherein the pipe supply mechanism 200 is arranged on one side of the catheter output of the workbench 100. The pipe clamping assembly 400 and the pipe winding clamping assembly 500 are arranged above the winding mechanism 300, and the moving assembly 600 drives the pipe clamping assembly 400 and the pipe winding clamping assembly 500 to translate. The catheter is stretched out of the roll and is limited in direction by a plurality of rolling rods 215, is guided through a guide 201, and is then passed out of a pipe cutting guide 208. The moving assembly 600 drives the pipe clamping assembly 400 to translate and move close to the pipe supply mechanism 200. After the pipe clamping assembly 400 is translated to a position, a pipe clamping element 401 in the pipe clamping assembly 400 is lowered to be close to the catheter and clamps one end of the catheter exposed from the pipe cutting guide 208. The pipe clamping element 401 clamps the catheter, and the catheter is moved to the winding mechanism 300 under the drive of the moving assembly 600. At this time, a catheter finger clamp two 313 in the winding mechanism 300 is located on a side away from the pipe supply mechanism 200. The pipe clamping element 401 moves the catheter to the catheter finger clamp two 313, and the catheter finger clamp two 313 clamps the catheter, and then the pipe clamping element 401 is reset under the drive of a lifting pipe clamping cylinder 403. A rotating disc 301 starts to rotate under the drive of a rotating drive module 309, and the catheter is wound on a winding column 302. When the winding mechanism 300 rotates, a lifting drive element 207 synchronously drives the pipe cutting guide 208 to gradually lift, so that the catheter is uniformly wound layer by layer. Figure 1 When the catheter is wound to a predetermined number of turns, at this time, the catheter finger clamp two 313 rotates to a side close to the pipe supply mechanism 200. The lifting drive element 207 drives the pipe cutting guide 208 to descend again, so that another catheter finger clamp two 313 can clamp the catheter between the pipe supply mechanism 200 and the winding mechanism 300. The pipe cutting guide 208 moves away from the guide 201 under the drive of a pipe cutting translation cylinder 212. After the pipe cutting guide 208 moves to a position, a pipe cutting element 209 moves up to cut the catheter passing out of the pipe cutting guide 208. Thus, the winding mechanism 300 has a wound catheter, the catheter is wound on the winding column 302, and both ends of the catheter are clamped by the catheter finger clamp two 313. Figure 4 Figure 4 ​The guide tube is extended from the cutting guide 208 and exposed on the side of the cutting guide 208 away from the guide 201. The pipe clamping assembly 400 is driven by the transfer assembly 600 to move again close to the pipe supply mechanism 200 to repeat the above-mentioned action. The pipe clamping assembly 400 is driven by the transfer assembly 600 to move together with the pipe clamping assembly 400, and the pipe clamping assembly 500 is driven by the transfer assembly 600 to move close to the winding mechanism 300. After the pipe clamping assembly 500 is moved above the winding mechanism 300, the guide tube finger clamp three 501 and the type limiting clamp 502 in the pipe clamping assembly 500 are driven by the lifting pipe moving cylinder 505 to move downward, and the two guide tube finger clamps three 501 clamp the guide tubes at the two guide tube finger clamps two 313 respectively, and the type limiting clamp 502 clamps the guide tube wound on the winding column 302. After the guide tube finger clamp three 501 and the type limiting clamp 502 complete the clamping, the lifting plate two 305 is driven by the servo drive module 311 to move downward, and the winding column 302 on the sliding block two 303 is driven by the lifting plate two 305 through the connecting rod structure to move close to the other winding column 302. When the two winding columns 302 are close to each other, the guide tube wound on the winding column 302 loses the restraint. The guide tube finger clamp three 501 and the type limiting clamp 502 move upward under the drive of the lifting pipe moving cylinder 505 to move the wound guide tube out of the winding column 302. The pipe clamping assembly 500 moves the wound guide tube to the next process under the drive of the transfer assembly 600.

[0047] The pipe supply mechanism 200 realizes the cutting and continuous feeding of the guide tube through the guide 201, the guide tube finger clamp one 202 and the pipe cutting assembly. The pipe cutting translation cylinder 212 drives the cutting guide 208 to reset to ensure that the clamped length of the guide tube is retained after cutting. The winding mechanism 300 is composed of a rotating disc 301, two winding columns 302 and a stroke controller. The stroke controller precisely controls the lifting of the push rod 310 through the servo drive module 311, adjusts the distance between the winding columns 302 through the connecting rod 304, and realizes the adjustment of the winding specification at the millimeter level. The transfer assembly 600 drives the pipe clamping assembly 400 and the pipe clamping assembly 500 to move together. The pipe clamping assembly 400 is moved to the winding mechanism 300 by the lifting pipe clamping cylinder 403, and the pipe clamping assembly 500 limits the height of the guide tube by the pipe pressing element 503 and fixes the shape by the type limiting clamp 502 to ensure stable movement of the finished product. The device integrates automatic feeding, precise winding and loss prevention design, and significantly improves production flexibility and efficiency. The technical problem of automatic winding of the guide tube and precise adjustment of the winding specification is solved.

[0048] The structure of each part will be introduced in detail below with reference to the drawings.

[0049] As shown in the accompanying drawings Figure 2 And 3As shown, the second fixed plate 102 is fixedly installed on the workbench 100, and four through holes are arranged on the second fixed plate 102, four linear bearings are arranged on the second fixed plate 102 through the through holes, four guide rods 206 are arranged in the corresponding linear bearings, and the top ends of the four guide rods 206 are fixedly connected to the translation switching cylinder 204, which is guided by the guide rods 206 and can be lifted and lowered relative to the second fixed plate 102. The bottom of the second fixed plate 102 is also fixedly provided with a lifting driving member 207, the driving end of the lifting driving member 207 is connected to the lifting plate 205, and the lifting driving member 207 can drive the lifting plate 205 to move up and down. The translation switching cylinder 204 is fixedly arranged on the lifting plate 205, and a mounting bracket 203 is fixedly connected to the driving end of the translation switching cylinder 204. The guide member 201, the catheter finger clamp 202 and the pipe cutting translation cylinder 212 are all fixedly arranged on the mounting bracket 203. The pipe cutting assembly includes the pipe cutting translation cylinder 212, a connecting member 213, a pipe cutting guide member 208, a pipe cutting member 209 and a pipe cutting cylinder 211. The position at which the catheter finger clamp 202 clamps the catheter is arranged between the guide member 201 and the pipe cutting guide member 208. The guide member 201 has a through hole, the pipe cutting guide member 208 has a through hole, the axis of the through hole of the pipe cutting guide member 208 is collinear with the axis of the through hole of the guide member 201, the size of the through hole of the pipe cutting guide member 208 is adapted to the diameter of the catheter, and the catheter sequentially passes through the guide member 201 and the pipe cutting guide member 208 and then passes out of the pipe cutting guide member 208. The driving end of the pipe cutting translation cylinder 212 is connected to the connecting member 213, the pipe cutting guide member 208 is arranged on the connecting member 213, a sliding member 210 is also slidably arranged on the connecting member 213, the sliding member 210 is located below the pipe cutting guide member 208, the sliding member 210 slides in the vertical direction, the pipe cutting member 209 is fixedly arranged on the sliding member 210, the pipe cutting cylinder 211 is fixedly arranged on the connecting member 213, the sliding member 210 is connected to the driving end of the pipe cutting cylinder 211, and the pipe cutting cylinder 211 drives the sliding member 210 to move upward to cut the catheter passing through the pipe cutting guide member 208. When the catheter is completely wound, the pipe cutting translation cylinder 212 drives the connecting member 213 to move, so that the pipe cutting guide member 208 moves away from the guide member 201, and the catheter is clamped by the catheter finger clamp 202, after the pipe cutting guide member 208 moves into position, the connecting member 213 drives the pipe cutting member 209 to move upward to cut the catheter. After the catheter is cut, the pipe cutting translation cylinder 212 drives the pipe cutting guide member 208 to move close to the guide member 201, so that the catheter in the pipe cutting guide member 208 can pass through the pipe cutting guide member 208 and re-expose a section, and this section of the catheter is convenient for the pipe clamping assembly 400 to clamp and pull.The pipe cutting guide 208, the pipe cutting member 209, the sliding member 210, the pipe cutting cylinder 211 and the connecting member 213 constitute a pipe cutting assembly. Two pipe cutting assemblies, the guide member 201, the pipe finger clamp 202 and the pipe cutting translation cylinder 212 are arranged on the mounting frame 203 in parallel. The translation switching cylinder 204 drives the mounting frame 203 to translate and switch different pipe cutting guide 208 to align the winding mechanism 300, so as to achieve the effect of continuous feeding. Each pipe cutting assembly further comprises a pipe sensor 214 arranged on the connecting member 213. The pipe sensor 214 is used to sense whether the pipe is exposed from the pipe cutting guide 208. Whether the pipe on the pipe cutting assembly is out of stock is judged by the detection of the pipe sensor 214. When the pipe sensor 214 does not detect the pipe, the translation switching cylinder 204 drives the mounting frame 203 to translate and moves another pipe cutting assembly to the position aligning the winding mechanism 300.

[0050] As shown in the accompanying drawings Figure 4 and 5 The fixed plate 101 is fixedly installed on the workbench 100. A through hole is formed in the fixed plate 101. A rotating bearing seat is arranged in the through hole. A rotating shaft 308 is rotatably arranged in the rotating bearing seat and relative to the fixed plate 101. The upper end of the rotating shaft 308 is fixedly connected to the mounting plate 306. The lower end of the rotating shaft 308 is fixedly connected to the driving end of the rotating drive module 309. The rotating drive module 309 can be a motor-driven synchronous wheel combination. The rotating shaft 308 is fixedly connected to the synchronous wheel. The motor is a servo motor or a stepper motor, which can control the rotation angle, so as to ensure the accurate control and adjustment of the winding turns. The rotating drive module 309 drives the rotating shaft 308 to rotate, thereby driving the mounting plate 306 to rotate. Four support rods 307 are fixedly arranged on the mounting plate 306 in the vertical direction. The top ends of the four support rods 307 are fixedly connected to the rotating disc 301. The support rods 307 support the rotating disc 301 and have a guiding effect. A linear bearing is sleeved on each support rod 307. The lifting plate 305 is connected to the linear bearings on the four support rods 307, so that the lifting plate 305 slides on the support rods 307 through the linear bearings. The lifting plate 305 is driven to move up and down by the servo drive module 311. The rotating shaft 308 is hollow. A push rod 310 penetrates the hollow through hole of the rotating shaft 308. One end of the push rod 310 is connected to the lifting plate 305 and the other end is connected to the driving end of the servo drive module 311. The servo drive module 311 drives the push rod 310 to move upward, thereby pushing the lifting plate 305 to lift upward. The push rod 310 is connected to the lifting plate 305 and the servo drive module 311. The lifting plate 305 rotates with the rotating shaft 308. The servo drive module 311 is fixedly arranged on the fixed plate 101. Therefore, the push rod 310 needs to be rotatably arranged relative to one of the lifting plate 305 and the servo drive module 311. Figure 4The middle push rod 310 is provided with a rotating bearing 314 at the connection position with the servo drive module 311, and the push rod 310 is rotatable relative to the servo drive module 311. It can be understood that the rotating bearing 314 can also be arranged at the connection position of the push rod 310 and the lifting plate 305. The rotating disc 301 is provided with a winding column 302, and there is at least one winding column in a group. There are at least two groups of winding columns 302, and the distance between the two groups of winding columns 302 can be adjusted. At least one group of winding columns 302 is slidingly arranged on the rotating disc 301. The sliding member two 303 is slidingly arranged on the rotating disc 301 through a sliding rail sliding block assembly, and the sliding direction of the sliding member two 303 intersects with the axis of the rotating shaft 308 in space. One group of winding columns 302 is fixedly connected to the sliding member two 303, so that the distance between the two groups of winding columns 302 can be adjusted. The sliding member two 303 is hingedly connected with a connecting rod 304, and the other end of the connecting rod 304 is hingedly connected to the lifting plate two 305. When the lifting plate two 305 is pushed to move upwards, the sliding member two 303 is driven to move outward of the rotating disc 301 through the connection of the connecting rod 304, and the winding column 302 on the sliding member two 303 moves away from the other winding column 302. The lifting of the lifting plate two 305 drives the two groups of winding columns 302 to move away from each other, and when different winding sizes are needed, the lifting height of the lifting plate two 305 can be accurately adjusted by the servo drive module 311 to accurately adjust the distance between the two groups of winding columns 302. The servo drive module 311 feeds back the lifting displacement of the push rod 310 through the encoder, and combines the transmission ratio of the connecting rod 304 to realize millimeter-level precision adjustment of the distance between the two groups of winding columns 302, solves the problem of single winding specification of the two groups of winding columns 302, and realizes the technical effect of accurate adjustment of the winding specification. The connecting rod 304, the lifting plate two 305, the push rod 310 and the servo drive module 311 form a stroke controller which can accurately control the position of the sliding member two 303. When the pipe winding clamping assembly 500 clamps the wound catheter away from the winding column 302, the servo drive module 311 drives the lifting plate two 305 to move downward to make the distance between the two groups of winding columns 302 smaller. The rotating disc 301 is further provided with an elastic member 312, one end of the elastic member 312 is connected to the sliding member two 303 and the other end is connected to the rotating disc 301. When the servo drive module 311 drives the lifting plate two 305 to move downward, the elastic member 312 resets the sliding member two 303 through tension, and the two groups of winding columns 302 move close to each other. The elastic member 312 can be a spring, a tension spring, or other parts that can play a role in elastic reset.

[0051] It can be understood that the two groups of winding columns 302 can also be driven to move close to each other by lifting the lifting plate two 305, which only needs to change Figure 5The orientation of the connecting rod 304. Two guide tube clamps 313 are also provided on the edge of the rotating disk 301. The two guide tube clamps 313 are located on both sides of the line connecting the two sets of winding columns 302 and are symmetrically arranged along this line. One guide tube clamp 313 clamps one end of the guide tube before winding, and the other guide tube clamps the other end of the guide tube after winding is completed.

[0052] As attached Figure 6 As shown, the support 700 is fixedly mounted on the workbench 100. The tube-moving drive component 601 is fixedly mounted on the support 700, and the translation plate 602 can be horizontally slidably mounted on the support 700 via a slide rail slider assembly. The lifting tube-clamping cylinder 403 is fixedly connected to the translation plate 602, and the driving end of the lifting tube-clamping cylinder 403 is fixedly connected to a gripper cylinder 402. The driving end of the gripper cylinder 402 is provided with two tube-clamping components 401. The lifting tube-clamping cylinder 403 drives the gripper cylinder 402 to move up and down, and the gripper cylinder 402 can drive the two tube-clamping components 401 to move closer or further apart. The lifting and moving cylinder 505 is fixedly connected to the translation plate 602. The driving end of the lifting and moving cylinder 505 is fixedly connected to the lifting plate 504. The conduit finger clamp 501, the clamping component 503, and the limiting clamping cylinder 507 are all fixedly mounted on the lifting plate 504. One of the clamping components of the conduit finger clamp 501 is equipped with a clamping plate 506. Both the clamping plate 506 and the clamping component 503 are used for clamping the conduit. The function of the clamping plate 506 is to press the conduit clamped at the conduit finger clamp 313 to a horizontal position, so that the exposed part of the conduit after being clamped by the conduit finger clamp 501 remains in a horizontal state. The clamping component 503 restricts the wound conduit to a fixed height through a downward pressing action, ensuring that the limiting clamp 502 can accurately clamp the middle section of the wound conduit. The tube transfer drive 601 drives the translation plate 602 to move horizontally, thereby causing the tube clamping assembly 400 and the tube winding clamping assembly 500, which are mounted on the translation plate 602, to move horizontally. After the tube winding clamping assembly 500 transfers the tube, the transfer assembly 600 drives it back above the winding mechanism 300, and the lifting and lowering tube transfer cylinder 505 resets, waiting for the next winding to be completed.

[0053] The process of transferring the tube using the transfer assembly 600: Both the tube assembly 400 and the tube coiling clamping assembly 500 are fixed to the translation plate 602. When the clamping member 401 in the clamping assembly 400 is driven to move downward to clamp the conduit on the tube supply mechanism 200, the conduit finger clamp 501 and the limiting clamp 502 in the tube coiling clamping assembly 500 are simultaneously driven to move downward to clamp the conduit on the winding mechanism 300. The translation plate 602 is driven to move in two stages. The first stage of translation causes the clamping assembly 400 to transfer the unwound conduit to the winding mechanism 300, and the second stage of translation causes the tube coiling clamping assembly 400 to transfer the wound conduit to the next process.

[0054] It should be noted that the pipe finger clamp mentioned in the above text includes a clamp cylinder and two pipe clamping pieces arranged at the driving end of the clamp cylinder, and the clamp cylinder drives the two pipe clamping pieces to approach and clamp the pipe.
