Description
Technical Field
The invention relates to a winding machine 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 machines capable of obtaining better product quality and improving the number of stacked layers and the winding speed.
Background
According to the winding method of the micro flat enameled wire with the cross-sectional dimension range of 0.025-0.1 mm in thickness and 0.19-0.35 mm in width, and the difference between the thickness and the width being about 10 times, which is used in the prior art, the micro flat enameled wire 14 is wound on a central support 92 (as shown in fig. 22-26), and the bonding layer on the surface of the micro flat enameled wire 14 is heated by hot air, so that the coil 141 is fixed in shape. The action is mainly that the wire feeding mechanism guides the micro flat enameled wire 14 into a winding jig 9 (as shown in fig. 22-26), the top end surface 91 of the winding jig 9 is a planar shape, the micro flat enameled wire 14 is clamped at the periphery of the winding jig 9, the central top pillar 92 is driven by the motor driving unit to press down the top end face 91 of the winding jig 9, the micro flat enameled wire 14 is leaned on the central top pillar 92, the outer ring 921 of the central top pillar 92 (as shown in fig. 24-26) 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 pillar 92 must be spaced apart by a certain distance (as shown in fig. 24) to avoid interference between the mechanism and the micro flat enameled wire 14, which may cause abrasion of the surface of the enameled film during 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 planar top end surface 91 of the winding fixture 9, and after the center is pressed back, the coil 141 is deformed to be inclined outward (as shown in fig. 24), and therefore, after a certain number of turns, the winding fixture 9 cannot maintain the shape of the coil 141, and a collapse portion a (as shown in fig. 25) or an outward-turning portion B (as shown in fig. 26) of the micro flat enameled wire 14 is formed, so that the defective product probability is relatively 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.
