Description

Technical Field

[0001] The utility model belongs to the technical field of winding machines, and particularly relates to an open-loop mechanism for a winding machine. Background Art

[0002] In the manufacturing process of inductance coils, a winding machine is a key technical device for winding a wire around an iron core according to specific rules to form an inductance coil. As one of the core components of the winding machine, the wire storage ring mainly functions to store the wire required for winding and control the regular winding of the wire onto the iron core, thereby ensuring the winding accuracy and consistency of the inductance coil.

[0003] Most of the wire storage rings used on winding machines are elastic annular structures with openings. The outer circumferential surface thereof is provided with grooves for winding, and wire holes or wire grooves are provided on the groove walls of the grooves so that the wire can pass through smoothly and be wound onto the iron core. During the winding process, the open-loop opening of the wire storage ring needs to be closed to form a complete annular structure to ensure the stability of the wire winding path; when the iron core is inserted, the open-loop opening of the wire storage ring needs to be opened for operation.

[0004] Patent document CN216004777U discloses an open-loop device, including: an open-loop guide wheel for opening the wire storage ring; a ring lifting device connected to the open-loop guide wheel for driving the open-loop guide wheel to pull open the wire storage ring; a side-pushing device connected to the ring lifting device for driving the open-loop guide wheel to drive the pulled-open part of the wire storage ring to shift to one side; and an open-loop groove for assisting in opening is provided on the open-loop guide wheel. When this open-loop device works, the ring lifting device drives the open-loop guide wheel to move upward to pull open the wire storage ring, and then the side-pushing device drives the open-loop guide wheel to move horizontally, thereby pushing the pulled-open part of the wire storage ring to one side. There are certain defects in the open-loop device in this patent document during actual use: the open-loop guide wheel can only move translationally and cannot deflect, resulting in a large torque between the wire storage ring and the open-loop groove during the pulling-open process. The wire storage ring is forced to bear additional torsional stress during the pulling-open process. The existence of this torque makes the contact between the wire storage ring and the open-loop groove unstable, thereby increasing the risk of the wire storage ring disengaging from the open-loop groove, further affecting the reliability of the open-loop operation of the wire storage ring, and also easily causing damage to the wire storage ring.

Detailed implementation manners

[0026] The embodiments of the technical solution of the present utility model will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to illustrate the technical solution of the present utility model more clearly, so they are only examples and cannot be used to limit the protection scope of the present utility model.

[0027] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meanings understood by those skilled in the field to which the present utility model belongs.

[0028] In the embodiment of the present utility model, the structure of the open-loop mechanism for a winding machine is as Figures 1 to 6As shown in the figure, it includes a mechanism frame 1, a guide wheel 2, a wire storage ring 3, and an open-loop drive module 4. The guide wheel 2 is installed on the mechanism frame 1 and is used to support and rotationally drive the wire storage ring 3. The wire storage ring 3 has an open-loop opening, and the open-loop drive module 4 is used to drive the open-loop opening of the wire storage ring 3 to open. The open-loop drive module 4 includes a drive unit 41 installed on the mechanism frame 1, a mounting block 42 driven by the drive unit 41 to move, an open-loop swing block 43 rotatably installed on the mounting block 42, and a limiting structure. The limiting structure is connected to the open-loop swing block 43, and the drive unit 41 is adapted to drive the mounting block 42 to perform lateral and lifting movements. When the mounting block 42 moves laterally, the open-loop swing block 43 is driven by the limiting structure to deflect relative to the mounting block 42. A card slot 431 adapted to be engaged with the wire storage ring 3 is provided on the open-loop swing block 43. During operation, the drive unit 41 drives the mounting block 42 to rise, the card slot 431 on the open-loop swing block 43 is clamped inside the wire storage ring 3 and pulls the open-loop opening of the wire storage ring 3 to be misaligned upward to open. Then, the drive unit 41 drives the mounting block 42 and the open-loop swing block 43 to move laterally and drives the open-loop opening of the wire storage ring 3 to be misaligned laterally. Moreover, during this lateral movement process, the open-loop swing block 43 is limited by the limiting structure to be able to deflect, and the deflection direction of the open-loop swing block 43 is adapted to the offset direction of the corresponding part of the wire storage ring 3. In this way, the wire storage ring 3 and the open-loop swing block 43 are kept stably connected, preventing the wire storage ring 3 from detaching from the open-loop swing block 43, ensuring the reliability of the open-loop operation of the wire storage ring 3, and effectively reducing damage to the wire storage ring 3.

[0029] See Figure 4 and Figure 5 As shown in the figure, the limiting structure includes a limiting rod 44 connected to the mechanism frame 1 and a swing rod 45 connected to the open-loop swing block 43. A limiting socket 451 is provided on the swing rod 45, and the limiting rod 44 is arranged in the up-down direction and inserted into the limiting socket 451, thus realizing the movable connection between the limiting rod 44 and the swing rod 45. With this structure, during the lateral movement of the open-loop swing block 43, the swing rod 45 rotates under the constraint of the limiting rod 44, thereby driving the open-loop swing block 43 to deflect. When the drive unit 41 drives the open-loop swing block 43 to move up and down, the limiting rod 45 does not interfere with the swing rod 45. Specifically, a mounting rod 10 is fixedly installed on the mechanism frame 1, and the limiting rod 44 is fixed on the mounting rod.

[0030] See Figure 6In order to stably install the open-loop pendulum block 43 on the mounting block 42, a supporting plane 421 is provided on the mounting block 42, and an abutting surface 430 is provided on the open-loop pendulum block 43, which is in contact with the supporting plane 421. The abutting surface 430 is in contact with the supporting plane 421, and a stable support can be formed for the open-loop pendulum block 43 through the contact between the abutting surface 430 and the supporting plane 421; a positioning pin 422 is fixed on the mounting block 42, and a positioning hole 432 is provided on the open-loop pendulum block 43, which cooperates with the positioning pin 422. The positioning pin 422 cooperates with the positioning hole 432 to enable the open-loop pendulum block 43 to rotate relative to the mounting block 42 to meet the deflection requirements of the open-loop pendulum block 43.

[0031] See also Figure 1 , Figure 2 and Figure 6 In order to ensure that the clamping groove 431 forms a stable and effective clamping connection with the wire storage ring 3, it is preferred to set the clamping groove 431 as an arc-shaped groove, the curvature of the arc-shaped groove is adapted to the curvature of the wire storage ring 3, so that the wire storage ring 3 can fit well with the arc-shaped groove, so as to effectively prevent the wire storage ring 3 from detaching from the arc-shaped groove during the opening process.

[0032] In this embodiment, the driving unit 41 includes a transverse driving unit 46 and a lifting driving unit 47. The transverse driving unit 46 is installed on the mechanism frame 1 to drive the mounting seat 48 to move transversely. The lifting driving unit 47 is installed on the mounting seat 48 to drive the mounting block 42 to move up and down. The mounting block 42 can be lifted and moved laterally through the coordinated work of the transverse driving unit 46 and the lifting driving unit 47.

[0033] See also Figure 5 The transverse drive unit 46 includes a transverse cylinder 461 fixedly connected to the mechanism frame 1, a connecting block 462 driven by the transverse cylinder 461 to move transversely, a linear bearing 463 fixed on the mechanism frame 1, and a transverse guide shaft 464 arranged to pass through the linear bearing 463; one end of the transverse guide shaft 464 is fixedly connected to the connecting block 462, and the other end is fixedly connected to the mounting seat 48; when the transverse cylinder 461 is extended or retracted, it drives the connecting block 462 to move transversely, and then drives the mounting seat 48 to move transversely through the transverse guide shaft 464, and then drives the lifting drive unit 47 to move transversely; in this solution, the transverse guide shaft 464 cooperates with the linear bearing 463 to accurately guide the mounting seat 48, ensuring that the mounting seat 48 remains stable during the transverse movement and reduces deviation or shaking.

[0034] See also Figure 5As shown, the lifting drive unit 47 includes a lifting drive member 471 fixed on the mounting base 48 and a lifting block 472 driven by the lifting drive member 471 to move up and down; the mounting block 42 is fixed on the lifting block 472; when the lifting drive member 471 expands and contracts, it drives the lifting block 472 to move up and down, and then drives the mounting base 48 to move up and down; in this embodiment, the lifting drive member 471 uses a cylinder; in actual operation, the lifting drive member 471 can also use a linear drive component such as an electric cylinder. In order to make the lifting movement of the lifting block 472 stable, a limiting guide post 481 is fixed on the mounting base 48, and a guiding sliding hole 473 matching the limiting guide post 481 is provided on the lifting block 472; the guiding sliding hole 473 is a strip-shaped hole arranged in the up and down direction; a limiting piece 475 for limiting the lifting block 472 is provided on the limiting guide post 481; the lifting block 472 can be resisted and limited by the limiting piece 475, so as to prevent the lifting block 472 from loosening.

[0035] Further, as shown in Figure 5 , a stop block A474 and a stop block B482 are respectively provided on the lifting block 472 and the mounting base 48, the stop block A474 and the stop block B482 are opposite to each other up and down, and a stop adjusting screw A49 is screwed on one of the stop block A474 and the stop block B482, by adjusting the position of the stop adjusting screw A49 in the up and down direction, the lifting stroke of the lifting block 472 can be controlled to prevent the lifting stroke of the lifting block 472 from being too large.

[0036] Continuing to refer to Figure 5 , a transverse adjusting block 483 is fixed on the mounting base 48, and a stop adjusting screw B484 is screwed on the transverse adjusting block 483; when the mounting block 42 moves transversely, it abuts against the mechanism frame 1 through the stop adjusting screw B484 to form a stop limit, so that the transverse movement stroke of the mounting base 48 can be limited; in actual application, the transverse movement stroke of the mounting base 48 can be adjusted by screwing the stop adjusting screw B44.

[0037] For those of ordinary skill in the art, other different forms of changes or variations can be made on the basis of the above description. It is not necessary and impossible to enumerate all the implementation manners here. And these obvious changes or variations derived from the essential spirit of the present invention still fall within the protection scope of the present invention.
