Description
Technical Field
The invention relates to a winding method of a miniature flat enameled wire coil, in particular to a winding method of a miniature flat enameled wire with the section size range of 0.025-0.1 mm in thickness and 0.19-0.35 mm in width, and belongs to the related technical field of winding methods which can obtain better product quality and improve the number of stacked layers and the winding speed.
Background
The winding method of the micro flat enamel wire with the sectional dimension range of 0.025 to 0.1mm in thickness, 0.19 to 0.35mm in width, and the difference of the thickness and the width being about 10 times is used in the prior art, which means that the micro flat enamel wire 14 (as shown in fig. 28 to 32) is wound around a central support 92 (as shown in fig. 28 to 32), and the following layer on the surface of the micro flat enamel wire 14 is heated by hot air, so that the shape of the coil 141 is fixed. The action is mainly that the wire feeding mechanism guides the micro flat enameled wire 14 to enter a winding jig 9 (as shown in fig. 28-32), the top end surface 91 of the winding jig 9 is in a planar shape (as shown in fig. 28-32), the micro flat enameled wire 14 is clamped at the periphery of the winding jig 9, the central top post 92 is driven by the motor driving unit to press the top end surface 91 of the winding jig 9 (as shown in fig. 20), the micro flat enameled wire 14 is leaned on the central top post 92, the outer ring 921 of the central top post 92 (as shown in fig. 30-32) presses the micro flat enameled wire 14 on the top end surface 91 of the winding jig 9, when the first layer and the second layer are overlapped, the outer ring 921 of the central top post 92 must be spaced apart by a certain distance (as shown in fig. 30), so as to avoid interference between the mechanism and the micro flat enameled wire 14, and abrasion of the enameled film surface caused by the interference, thereby affecting the quality of the product. The center post 92 and the outer ring 921 need to be pressed back to the coil 141 to maintain the outer dimension after winding the layer by the distance of the clearance, which prolongs the tact speed and productivity.
In the winding process, a gap is formed between the end of the first layer and the plane of the winding jig 9, and after the center of the coil is pressed back, the coil 141 is deformed to be inclined outward (as shown in fig. 30), so that after a certain number of turns, the winding jig 9 cannot maintain the shape of the coil 141, and a collapsed portion a (as shown in fig. 31) or an outward-turned portion B (as shown in fig. 32) is formed, and the defective product probability is high.
The product design end is therefore unable to design products beyond this physical limit, affecting the industry's trend and design limits are depressed.

the central jacking mechanism (4) is driven by the central jacking Z-axis servo linear module (40) to continuously move towards the Z-axis direction, so that the outer ring (45) of the central jacking mechanism compresses the miniature flat enameled wire (14);
a lower main shaft servo motor (33) of a main shaft mechanism (30) is controlled to start and rotate, and is linked with at least one transmission shaft (32) through a synchronous belt set (39) to drive a winding jig (3) combined above the transmission shaft (32) to rotate, a central top S shaft servo motor (42) is also started synchronously with the lower main shaft servo motor (33) to rotate synchronously, and then the miniature flat enameled wire (14) can be wound on a central top column (41);
an outer ring (45) of the central jacking mechanism (4) is driven by a central jacking S-axis servo motor (42), and the outer ring (45) rises by a width along the Z-axis direction every time the central jacking S-axis servo motor (42) rotates for one turn, wherein the width is larger than or equal to the thickness of the miniature flat enameled wire (14);
in the steps, the winding starts the hot air device (5) at the same time, and hot air is sprayed out from the hot air nozzle (51), so that the outer coating adhesion layer of the miniature flat enameled wire (14) generates viscosity, and a coil (140) formed by winding can be adhered and fixed;
in the above steps, after the preset coil number and the preset forming angle are reached, the lower main shaft servo motor (33) stops driving the transmission shaft (32) to rotate, and the center top S-axis servo motor (42) is also controlled to stop rotating;
the wire clamping mechanism (2) is driven by the first linear driving module (23) and the second linear driving module (24) to displace to the tangent line position of the right edge of the winding jig (3) along the Y-axis and Z-axis directions, and controls a pneumatic wire clamping pliers (25) to clamp the wire and cut off the miniature flat enameled wire (14);
the center top mechanism (4) is driven by a center top Y-axis linear module (43) and moves to the position above a cutting mechanism (6) along the Y-axis direction;
the center top Z-axis servo linear module (40) of the center top mechanism (4) drives the center top column (41) to be driven by a center top column Z-axis driving module (44) to move upwards and separate from the coil (140), so that the coil (140) falls on the cutting jig (61) of the cutting mechanism (6);
the center jacking mechanism (4) is driven by a center jacking Y-axis linear module (43) and a center jacking Z-axis servo linear module (40) to move back to the center position of the winding jig (3) along the directions of Y axis and Z axis;
controlling a front and rear cutting cylinder (62) of the cutting mechanism (6) to move the cutting jig (61) to the position of the upper and lower cutting cylinders (63), and controlling the upper and lower cutting cylinders (63) to act to cut off the redundant part (1401) of the miniature flat enameled wire of the coil (140) to obtain a coil finished product (140');
after the cutting in the previous step, the redundant waste wire is discharged to a waste wire box through a waste wire discharge pipeline (64), the cutting upper and lower cylinders (63) are controlled to return to the original position, the cutting front and rear cylinders (62) return to the original position, and the coil finished product (140') is withdrawn by the cutting demoulding cylinder (66) and is discharged to a material box through a finished product discharge pipeline (65).
2. The method for winding a miniature flat enameled wire coil according to claim 1, wherein: the spiral surface (351) above the winding die (35) of the winding jig (3) is based on the top end surface (350) of the winding die (35), the bottom (3511) of the spiral surface (351) is the lowest, the spiral surface is gradually lifted from bottom to top from the bottom (3511), and the upper end edge (3512) of the spiral surface (351) is connected with the top end surface (350) of the winding die (35).
