Wire stripping method and mechanism

The invention relates to a wire stripping method and a mechanism, in particular to a wire stripping method and a mechanism for removing a wire coating film wound on a core.

According to the general power inductor component, it is often required to wind a wire on a core. The core usually comprises: a first flange at the two ends, a second flange and a core portion located therebetween; No. 201445597, "Method and Apparatus for Manufacturing Coil and Coil", the method of winding a wire on a core is proposed, wherein when the core of the core is wound around the wire, the wire inlet end and the outlet end are respectively But in the same direction, the first flange is bent and fixed to the first flange, and the fixing manner is only fixed by the conductive material such as tin liquid without welding, and is on a machine. The winding and dip soldering process is completed by two intermittent rotating flow paths, wherein the wire cutting end and the outlet end cutting mode adopt a wire breaking device, which comprises a frame and can be subjected to the sliding rail of the frame. a knife seat driving member is configured to move the upper and lower sliding displacement seat, the upper end of the knife seat is provided with a cutting edge on one side, the knife seat is pivotally connected on both sides, and is connected by an indirect pulling drive driven by a second blade seat driving member. Piece action, and can be tilted to the blade side Oblique, the degree of inclination is limited by the connecting member with a side contact member against a limiting member, and the boring holder is provided with a boring hole; and by the initial step, the turning step, the squeegeing step, the pressing line Eight steps, such as a step, a turning step, a loosening step, and a scraping step, to complete the cutting of the wire inlet end and the outlet end of the wire; The applicant has proposed the publication No. 201521056 "Coil manufacturing method and device", which proposes a film removal module which is provided with a frame on which a moving seat is driven by an infeed drive member for up and down Displacement and displacement by a diaphragm drive member for front and rear displacement, a film tool; the film removing tool can perform an enamel film removing operation of the wound wire corresponding to the coil clamped on the jig; wherein the film removing tool on the moving block of the film removing module is a plurality of scraping blades or For the grinding wheel.

In the case of the prior art publication No. 201445597, when the wire core is wound by the core of the core, the wire end and the wire end are bent from the first flange side in the same direction and are respectively covered by the same. The first flange is fixed, and it has to undergo eight steps, such as an initial step, a turning step, a blade step, a crimping step, a turning step, a loosening step, and a scraping step, to complete the cutting of the wire inlet end and the outlet end of the wire. The efficiency of the cut line needs to be improved. Since the disconnection device is only a workstation in the intermittent rotary flow path, a single workstation is time consuming and will affect the output in the entire intermittent rotary flow path; The film removing tool in the technical publication No. 201521056 is a plurality of scraping blades or grinding wheels. Since the scraper itself is scraped by a single blade portion, the blade wear is easily passivated, and the grinding wheel itself is composed of fine sand particles, particles and particles. There is a gap between them, so the fine sand particles have to maintain a sharp grinding effect, but the fines of the lacquer that are removed by the wire will get stuck in the clearance of the fine sand particles, and the grinding wheel will be passivated after a period of use. In addition to the loss of sharp grinding effect, easily lead paint coated wire scraping effect of the poor! Moreover, the scraper and the grinding wheel are single straight blade portions or curved surface grinding surfaces, and it is not possible to apply a wire having parallel connection between the inlet end and the outlet end to perform scraping.

Therefore, an object of the present invention is to provide a wire stripping method which can be used for stripping a wire of a core winding.

Another object of the present invention is to provide a wire stripping mechanism that can be used to remove the enamel film of a wire.

The wire stripping method according to the object of the present invention comprises: stripping a wire for winding a core, the core comprising: a first flange at the two ends, a second flange, and the first a winding core portion between the flange and the second flange, the wire is wound around the core portion, and is folded to the first flange by an incoming end and an outgoing end; and includes: providing a roll that can be displaced a knife holder; a cutter provided on the cutter holder and rotatable by driving, the cutter comprising a first wheel cutter and a second wheel cutter spaced apart in the axial direction; the cutters are spaced apart The first round knife and the second round knife respectively correspond to the wire inlet end and the outlet end of the iron core, and perform the operation of rolling the paint coating on the wire inlet end and the outlet end of the first flange of the iron core.

According to another object of the present invention, a wire stripping mechanism includes: a hob holder that can be driven to be displaced; and a hob disposed on the hob holder for being driven to rotate, including a spacing in the axial direction. The first round of the knife and the second round of the knife.
