The utility model increases end cap at the two ends of magnetic core, and guide pin is welded on the end cap.Press-fit end cap and adopt automation pressure cap equipment, end cap is fitted in the two ends of FERRITE CORE or ceramic core.After end cap press-fits, adopt Special Automatic butt-joint equipment with the lead butt-joint on end cap.The utility model makes by the end cap structure that increases finishes welding sequence when can finish winding process by the automation professional equipment, for the axial production automation of wire wound inducer provides solution completely.
Description of drawings
Fig. 1 is the structural representation () of the axial wire wound inducer of the utility model;
Fig. 2 is the structural representation (two) of the axial wire wound inducer of the utility model.
Embodiment
Below in conjunction with accompanying drawing the axial wire wound inducer of the utility model is described in further detail.
As shown in Figure 1, axial wire wound inducer described in the utility model mainly is made up of with enamelled wire 2 magnetic core 1, end cap 3, guide pin 5, and concrete application product also has other surfaces, as colour loop inductance UV coating, topcoat and colour circle 4 is arranged.The two ends of magnetic core are cylinder, and end cap is a cylindrical shell, and the two ends of magnetic core and end cap inner chamber base angle are rounded down, and end cap is fitted on the two ends of magnetic core, and the guide pin butt-joint is on the end cap at two ends.Magnetic core is FERRITE CORE or aluminium oxide ceramics core (comprising exposed aluminium oxide ceramics core and the aluminium oxide ceramics core that coats with the soft magnetic ferrite slurry), magnetic core is cylindrical or be with the cylindrical I-shaped wire casing that has, guide pin is tinned wird or CP wire or copper tinned aluminum wire or aluminium alloy wire, perhaps other tinned conductor material.End cap adopts copper coin or steel plate or other sheet metal material to be stamped to form.The physical dimension of FERRITE CORE or aluminium oxide ceramics core, end cap physical dimension and the diameter dimension of selecting guide pin for use can be with reference to the dimensional requirements of colour loop inductance GB.The main manufacturing process of the axial plug-in unit inductor of the utility model is as follows:
Press-fit end cap: press-fit the end cap operation and adopt automation pressure cap equipment, end cap is fitted in the two ends of FERRITE CORE or ceramic core;
The butt-joint guide pin: after end cap press-fits, adopt Special Automatic butt-joint equipment with the lead butt-joint on end cap;
Soldering tip and coiling: spooling equipment and technology that the utility model is used for reference, transplanted ripe and the colour circle resistance that winds the line efficiently, maturation along with " enamelled wire spot-welding technology ", adopt FERRITE CORE or ceramic core that end cap is installed, with the enamelled wire automatic winding that winds the line, utilizing subsidiaryly has the special-purpose coil winding machine of the employing enamelled wire spot-welding equipment of braid mechanism after detachment feed and the coiling blanking to finish coiling and weld job and braid simultaneously, thereby realizes full-automatic soldering tip and coiling: workpiece in the detachment-initial line spot welding-coiling-take-up spot welding-following workpiece and braid.
The last colour loop inductance coating machine that utilizes one's own profession generally to adopt already again adds the mounting and dismounting band feeding machanism and carries out application, test, tape package.
The utlity model has following advantage: because the design of manufacturing equipment and flow process is " building block system ", rather than " continuous-flow type ", the coil winding machine single axle, when processing broken string, feed interruption and replacing product type etc. are unusual, and the maintenance, all can not cause big loss to output when safeguarding, the problem of having avoided output to decline to a great extent; Because the difference of method of clamping, the coil winding machine that the utility model adopts must not be changed anchor clamps when changing product type, need only call the winding former block instruction of corresponding product; The utility model adopts the welding of enamel-covered wire spot-welding technology, and quality of welding spot is high, need not scaling powder, so can not produce any dry joint or electric leakage situation; Solder joint tiny (about 0.5 square of mm), accurate welding control can heavily be overlying on each solder joint; Soldering tip pressure, weldingvoltage and weld interval that in advance adjustment is fit to store and lock, and prevent that the operator from changing because of false touch; Meet the RoHS requirement fully, because thoroughly stop to pollute without scolder and scaling powder; Welding process can not produce foreign matter and cause line short; Pad has high anti-ambient temperature and humidity and the shatter-proof characteristics of swinging, by the checking of U.S.'s military discipline; Not discarded enamel-covered wire is saved cost, need not scaling powder, so need not to wash material before application, saves and cleans cost; With supporting other equipment of coil winding machine, be resistance cap cap presser and lead-in wire butt-joint braider, all be the mature equipment of producing resistance, anchor clamps are changed slightly and are got final product, and equipment processing ability is very high; Compare with existing pin connecting machine, the high material of saving of first-pass yield, and exempt from can eat up part of even offset the cost that increases end cap with glue and economize on electricity; Lead welding machine design braid mechanism, coil winding machine design detachment, braid mechanism; Although multiplex braid material so that can a people many-valued, and also adopts detachment mechanism when application, need not special blanking personnel, and solve the paint line blanking problem that gets stuck, guaranteed the application peak efficiency; All realize automation and inter process with the handing-over of braid form because comprise the feed whole process, the fraction defective straight line descends.
The utility model can also apply to adopt identical structure, and adopts other applications or packaged type, such as only requiring what UV applied, such as the derived product of doing other shapings, braid.
Application and colour circle are only covered the part of magnetic core middle part coiling, and the terminal that the remaining end cap portion is installed as the surface is used SMD carrier band packing instead behind the excision lead-in wire, can develop is the SMD winding inductor of SMD.
