Description

Technical Field

[0001] The utility model relates to the technical field of winding machines, in particular to a coil winding machine for medical equipment. Background Art

[0002] A coil winding machine for medical equipment is an automated or semi-automated mechanical device specifically used for manufacturing or repairing coils used in medical equipment.

[0003] Chinese Patent Publication No. CN218988446U, published on May 9, 2023, discloses a medical suture winding machine, which includes a base. The upper surface of the base is sequentially fixedly connected with a first support plate, a second support plate, and a third support plate. The outer surface of the first support plate is rotatably connected through a wire release roller, and a medical suture wire release disc is fixedly sleeved on the outer surface of the wire release roller. One side of the outer surface of the second support plate is symmetrically rotatably connected with two guide rollers. A tension automatic adjustment mechanism is fixedly installed on the upper surface of the base at a position between the two guide rollers. The outer surface of the third support plate is rotatably connected through a first support roller, and a second support roller is slidably connected to one end of the first support roller. A plurality of openings are sequentially formed on the outer surfaces of the first support roller and the second support roller.

[0004] In the process of guiding the wire core by the existing coil winding machines for medical equipment such as the above, a wire core tensioning mechanism is often added to avoid the wire core from being overly tightened or loose.

[0023] Please refer to Figures 1-4 , the present invention provides a technical solution:

[0024] A coil winding machine for medical equipment, including a frame 1, a three-jaw chuck 2 and a tailstock 3. A fixed seat 4 is fixedly connected to the top of the frame 1. A moving seat 6 is movably connected between the fixed seat 4 and the frame 1. A guide wheel 7 is rotatably integrated on one side of the moving seat 6. A vertical bar 10 is fixedly connected to the outer surface of the moving seat 6 through a cross bar 9. A top bin 11 is fixedly connected to the top of the vertical bar 10. A servo motor 12 is fixedly connected to the outer surface of the top bin 11. The output end of the servo motor 12 is integrated with a guiding component for guiding the wire core;

[0025] The core seat is connected between the three-jaw chuck 2 and the tailstock 3 of the center drill. The wire core passes through the wire arranging sleeve 16 and is connected to the core seat via the guide pulley 7. The three-jaw chuck 2 drives the core seat to rotate, thereby winding the wire core onto the core seat. During this process, the servo motor 12 drives the swing rod 15 to reciprocate and deflect at a specified angle. The swing rod 15 is linked to the wire arranging sleeve 16, and the wire arranging sleeve 16 will lift and reset the wire core locally. In this way, while the wire core is arranged on the core seat orderly, the tension of the wire core conveying is periodically realized, without the need for manual observation of the wire core conveying state, ensuring the stability of the use of the coil winding machine for medical equipment.

[0026] Specifically, as Figure 2 shown in Figure 4 , a connecting sleeve 13 is fixedly connected to the open end of the cross bar 9. The connecting sleeve 13 is sleeved on the outer wall of the vertical bar 10, and a positioning portion for positioning the vertical bar 10 is provided on the outer wall of the connecting sleeve 13.

When the vertical bar 10 is vertically moved, while the vertical bar 10 slides on the inner wall of the connecting sleeve 13, the vertical bar 10 is linked to the top bin 11 until the height of the top bin 11 reaches a suitable position. Then, the positioning rod 14 is rotated, and the outer wall of the positioning rod 14 is screwed with the inner wall of the connecting sleeve 13 until the open end of the connecting sleeve 13 abuts against the outer wall of the vertical bar 10, and the positioning of the vertical bar 10 is achieved through friction, so that the starting height of the top bin 11 can be conveniently adjusted according to the use requirements, thereby improving the convenience of the use of the coil winding machine for medical equipment.

[0027] Specifically, as Figure 2 shown in Figure 3 , a slide bar 5 is fixedly connected to the outer wall of the fixed seat 4.

A limiting frame 17 is fixedly connected to the outer wall of the top bin 11, and the limiting frame 17 is erected on the outer wall of the swing rod 15, so as to limit the swing angle of the swing rod 15 while improving the stability of the movement of the swing rod 15.

[0028] Working principle: The core seat is connected between the three-jaw chuck 2 and the tailstock 3 of the center. The wire core passes through the wire arranging sleeve 16 and is connected to the core seat via the guide pulley 7. The three-jaw chuck 2 drives the core seat to rotate, so as to wind the wire core onto the core seat. During this process, the servo motor 12 drives the swing rod 15 to reciprocally deflect at a specified angle. The swing rod 15 is linked with the wire arranging sleeve 16, and the wire arranging sleeve 16 will lift and reset the wire core locally. In this way, while the wire core is orderly arranged on the core seat, the tension of the wire core conveying is periodically realized, without the need for manual observation of the wire core conveying state, ensuring the stability of the coil winding machine for medical equipment. Vertically move the vertical rod 10. While the vertical rod 10 slides on the inner surface wall of the connecting sleeve 13, the vertical rod 10 is linked with the top bin 11 until the height of the top bin 11 reaches a suitable position. Then rotate the positioning rod 14. The outer surface wall of the positioning rod 14 is screwed with the inner surface wall of the connecting sleeve 13 until the open end of the connecting sleeve 13 abuts against the outer surface wall of the vertical rod 10, and the positioning of the vertical rod 10 is realized through friction, so that the starting height of the top bin 11 can be conveniently adjusted according to the use requirements, thereby improving the convenience of the coil winding machine for medical equipment.
