The working principle of the fully-automatic flat wire horizontal winding inductance coil production equipment 100 in the embodiment is as follows: the flat wire enters the lower winding module 33 through the flat wire feeding module 31 and is clamped by the wire clamping assembly 337, then the winding shaft core 3210 in the upper winding module 32 descends and is inserted into the coil holder 336 to be aligned with the coil holder, the winding shaft core 3210 starts to rotate, meanwhile, the coil holder 336 rotates at twice of the rotating speed of the winding shaft core 3210 to wind the coil, and in the winding process, the hot air blowing module 34 blows out hot air to bond the wire to wind the wire; after winding, the wire cutting module 35 cuts the wire, the wire clamping assembly 337 is loosened, the upper winding module 33 places the coil in the jig 2, and the wire pins are primarily shaped at the coil loading station through the wire pin shaping unit 10, so that the subsequent pre-bending operation is facilitated; then the wire stand is rotated to the next work station, and the wire stand is bent into a vertical state through the wire stand pre-bending unit 4; then the next station is rotated, and the framework feeding unit 5 assembles the framework on the coil; then the coil is rotated to the next station, and the stitch bending and pressing unit 6 presses the stitch of the coil on the upper surface of the framework from the horizontal state to the reverse direction and completely presses the stitch in place; then the operation is rotated to the next station, and the stitch is welded on the framework through the welding unit 7, so that the connection and the assembly with the framework are realized; then rotate to the unloading station to detect through the CCD camera, detect qualified product and carry out the unloading through unloading unit 8, unqualified rotation is clear away to next station.

According to the full-automatic flat wire horizontal winding type inductance coil production equipment 100, a set of automatic winding, stitch pre-bending, framework loading and assembling, stitch attaching framework bending, coil framework welding, detection, automatic blanking and receiving and other automatic processing technologies are realized for a flat wire horizontal winding coil, and the production efficiency and the production quality of a flat wire horizontal winding type inductance coil are greatly improved; aiming at the automatic production of a miniature inductance coil, the production precision is greatly improved, and the product quality is guaranteed; the terminal is bent in place in two bending steps by arranging the terminal pre-bending unit and matching with the subsequent terminal bending pressing unit, so that the problem that the crushing framework is easy to occur when the flat wire is hard in bending is effectively solved; the coil pin shaping unit for shaping the coil pins is arranged at the coil loading station, so that the position uniformity of the coil pins before bending is ensured, the smooth bending and the bending quality of the subsequent coil pins are ensured, and the high-precision production of the micro-miniature coil is realized.

What has been described above are merely some of the embodiments of the present invention. It will be apparent to those skilled in the art that various changes and modifications can be made therein without departing from the spirit and scope of the utility model.
