[0031] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention.

[0032] like Figure 1 As shown, the present invention provides a connecting catheter coil device, comprising a frame 1, a grabbing mechanism 2 arranged above the frame 1, and a guide conveying mechanism 3 and a coiling mechanism 4 sequentially arranged on the frame 1 along the moving direction of the grabbing mechanism 2;

[0033] In this embodiment, the frame 1 is used to support each component. The frame 1 is made of square pipes welded together, and a foot pad for leveling is provided at the bottom. The grabbing mechanism 2 can be used to clamp the finished product after connecting the conduit or coiling and move it. The guiding conveying mechanism 3 can guide the pipe material entering the coiling mechanism 4 to maintain the stability of the material feeding. The coiling mechanism 4 is used to realize automatic coiling and improve the product quality. The specific structure of each component of the device is as follows:

[0034] like Figure 2As shown, the gripping mechanism 2 includes a straight-line moving assembly 21 arranged above the frame 1, and a pipe material clamping assembly 22 and a coil pipe clamping assembly 23 arranged at intervals, and the pipe material clamping assembly 22 and the coil pipe clamping assembly 23 are both connected to the straight-line moving assembly 21; wherein, the pipe material clamping assembly 22 includes a first lifting cylinder 221 connected to the straight-line moving assembly 21 and a pneumatic pipe material clamp 222 arranged below the first lifting cylinder 221; the coil pipe clamping assembly 23 includes a second lifting cylinder 231 connected to the straight-line moving assembly 21, a claw plate 232 arranged below the second lifting cylinder 231, and a plurality of pneumatic coil pipe clamps 233 uniformly distributed circumferentially below the claw plate 232, and the pneumatic coil pipe clamps 233 correspond one-to-one to the notches 44a.

[0035] The pneumatic pipe clamp 222 of the pipe material clamping assembly 22 is used to clamp the pipe head of the connecting conduit, and its height adjustment can be controlled by the first lifting cylinder 221 on the linear travel assembly 21. The pneumatic coil clamp 233 in the coil clamp assembly 23 is used to clamp the finished product of the connecting conduit after the coil. In this embodiment, there are four pneumatic coil clamps 233 to ensure the stability of the finished product during clamping and transportation. The height adjustment of the pneumatic coil clamp 233 is also controlled by the second lifting cylinder 231 on the linear travel assembly 21. Among them, the claw plate 232 and the second lifting cylinder 231 are detachably connected by an angle code. In addition, a tank chain is also provided on the linear travel assembly 21 to facilitate the operation of the pipe material clamp assembly 22 and the coil clamp assembly 23.

[0036] like Figure 3-4 As shown, the guide conveying mechanism 3 includes a servo linear module 31 vertically arranged on the frame 1, a T-shaped plate 32 horizontally arranged on the servo linear module 31 and a pipe guide assembly 33 arranged on the T-shaped plate 32; wherein, the pipe guide assembly 33 includes a guide groove 331 arranged above the T-shaped plate 32 and a guide wheel group 332 and a guide clamp 333 respectively arranged at both ends of the guide groove 331, an anti-slip unit 334 is arranged in the middle of the guide groove 331, the guide wheel group 332 can approach or move away from each other under the drive of the pneumatic finger 335 arranged on the T-shaped plate 32, the guide clamp 333 is provided with an arc-shaped opening facing the annular groove 44, and the guide clamp 333 can move along a direction perpendicular to the length of the guide groove 331.

[0037] The guide wheel group 332 is used to clamp the rear end of the connecting conduit. The spacing of the guide wheel group 332 can be adjusted by the pneumatic fingers 335 to adapt to the loading of connecting conduits with different diameters. The anti-slip unit 334 limits the jumping of the connecting conduit in the guide groove 331 from above. The arc-shaped mouth of the guide clamp 333 cooperates with the annular groove 44 to limit the front end of the connecting conduit, so that the pipe guide assembly 33 can stably transport the connecting conduit and prevent the jumping phenomenon during the loading process. During the coiling process, the connecting conduit on the coiling mechanism 4 will spiral up. To cooperate with this process, the servo linear module 31 can drive the pipe guide assembly 33 to rise stably through the T-plate 32, and the servo linear module 31 can accurately control the lifting height.

[0038] Preferably, the anti-slip unit 334 includes an aluminum profile 3341 fixed on the top of the servo linear module 31, a slider 3342 slidably set on the T-shaped plate 32, a tension spring 3343 connecting the slider 3342 and a pressure rod 3344 horizontally inserted into the guide groove 331. The aluminum profile 3341 includes a rectangular guide part and a triangular switch part from bottom to top. The sliding direction of the slider 3342 is perpendicular to the length direction of the guide groove 331. The slider 3342 is connected to a roller 3346 through a connecting piece 3345. Under the action of the tension spring 3343, the roller 3346 always slides close to one side of the aluminum profile 3341. The pressure rod 3344 is fixedly connected to the slider 3342, and a spacing is left between the pressure rod 3344 and the bottom of the guide groove 331.

[0039] As the roller 3346 rises along the guide portion, the pressure rod 3344 is always inserted into the guide groove 331 to press the connecting conduit in the groove. When the coil is nearly completed, the roller 3346 rises to the switch portion. Due to the structure of the switch portion itself, the slider 3342 is acted upon by the tension spring 3343, and the pressure rod 3344 is pulled out of the guide groove 331 and no longer presses the connecting conduit, which is beneficial to the smooth discharge of the tail of the connecting conduit.

[0040] like Figure 5-9As shown, the coil mechanism 4 includes a bottom plate 41 arranged above the frame 1, a steering motor 42 arranged below the bottom plate 41, and a turntable 43 arranged above the bottom plate 41. The output shaft of the steering motor 42 passes through the bottom plate 41 and is connected to the turntable 43 in a transmission manner. A circular groove 44 is arranged around the upper end of the turntable 43. A plurality of notches 44a that can cooperate with the grabbing mechanism 2 are opened around the circular groove 44. A pipe clamping assembly 45 for fixing the pipe material is arranged inside the circular groove 44. A pipe pushing assembly 46 for pushing the pipe material to the turntable 43 is arranged outside the turntable 43. The pipe clamping assembly 45 includes an L-shaped seesaw 451, an arc-shaped slot plate 452 and a spring 453. The seesaw 451 is turned to rotate. The corner is rotatably mounted on the lower end of the turntable 43 through a connecting seat 454, the rocker 451 has a vertical portion passing through the turntable 43 and a horizontal portion located below the turntable 43, the slot plate 452 is fixedly connected to the vertical portion and its arc opening faces the turntable 43, the two ends of the spring 453 are respectively connected to the turntable 43 and the horizontal portion, and the horizontal portion can be rotated under the drive of the opening and closing cylinder 455 arranged on the base plate 41; wherein, the push tube assembly 46 includes a translation cylinder 461 fixed on the base plate 41, a vertical rod 462 arranged on the translation cylinder 461 and a U-shaped push rod 463 arranged on the top of the vertical rod 462, and the translation cylinder 461 drives the U-shaped push rod 463 to move toward the annular groove 44 through the vertical rod 462.

[0041] After the steering motor 42 drives the turntable 43 to rotate to a suitable position, the opening and closing cylinder 455 lifts the seesaw 451 of the clamping tube assembly 45, and the seesaw 451 flips a certain angle to open the clamping slot plate 452, and the pipe material clamping assembly 22 clamps the head of the connecting pipe and puts it under the clamping slot plate 452, and the opening and closing cylinder 455 resets, and the seesaw 451 drives the clamping slot plate 452 to close and clamp the head of the connecting pipe under the action of the spring 453, and then the steering motor 42 drives the turntable 43 to rotate again, and the connecting pipe is automatically coiled. When the tail of the connecting pipe moves out of the guide conveying mechanism 3, the translation cylinder 461 of the push tube assembly 46 drives the U-shaped push rod 463 to push the tail of the connecting pipe into the annular groove 44, and wait for the coiling clamping assembly 23 to be taken out after the finished product is completed. Preferably, one of the rod end faces of the U-shaped push rod 463 is arc-shaped, so as to better fit the connecting pipe, and the other rod end face is L-shaped, and this design can ensure that it is fully pushed into place.

[0042] The working principle of this embodiment is as follows: when in use, the grabbing mechanism 2 is started, the pipe material clamping assembly 22 automatically clamps the head of the connecting conduit to be coiled, and moves to the coiling mechanism 4 under the drive of the linear travel assembly 21; the coiling mechanism 4 is started, the pipe material clamping assembly 22 puts the head of the connecting conduit to the clamping assembly 45, and the clamping assembly 45 fixes it, and then the steering motor 42 drives the turntable 43 to rotate, so that the connecting conduit is automatically coiled in the annular groove 44; at the same time, the guide conveying mechanism 3 is started, and the servo linear module 31 drives the pipe material guide assembly 33 to rise to cooperate with the coiling action to maintain stable feeding. When the coiling is nearly completed, the pipe pushing assembly 46 pushes the tail of the connecting conduit into place, and the coiling is completed to complete the finished product. Finally, the coiling clamping assembly 23 clamps the finished product and moves to the lower moving station under the drive of the linear travel assembly 21.

[0043] The present invention is not limited to the above-mentioned specific implementation modes. For ordinary technicians in this field, various changes made based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
