Description
Technical field
The present invention relates to resistor, relate in particular to a kind of resistance wire winding method.
Background technology
Accurate wound potentiometer as the control device of a kind of signal controlling, transmission, needs very long useful life, very high electric property, linearity electric parameter index is wherein involving the series of process difficulty, and especially on the skeleton during around resistance wire, this difficulty just shows more outstandingly.
In the prior art, generally adopt following two kinds of technique for coiling:
1) first kind of process is: directly resistance wire is wound on the skeleton, the reliability of this method and useful life are very low, as shown in Figure 1, in use, because brush plate 7 constantly slidably reciprocates on resistance wire 30, then can cause part resistance wire 30 to produce and move, as shown in Figure 1, the normal separation of supposing resistance wire 30 is Lm, obviously, because resistance wire 30 mobile produced than bigger spacing Lp of Lm and the spacing Lq littler than Lm, thereby changes the original intrinsic linearity of potentiometer, make linearity variation, instability, serious even produce fracture of wire open circuit phenomenon, its reliability is very low.
2) second kind of process is: as shown in Figure 2, employing has the resistance wire of insulating barrier, critically be wound on the skeleton, again through after soaking the insulating varnish oven dry, with special customization grinding machine, the insulating barrier on resistance wire surface subtly rubbing down fall, make resistive element, at this moment resistance wire can not move left and right on skeleton, the potentiometer of making like this, moving brush sheet slides on the resistance skeleton, the resistance wire displacement has taken place never again, but existed many defectives in this technology: technology is quite complicated, rate of finished products and yielding poorly, especially in precise polished operation, adopt the specific customization precision grinder, cost price is high, the scrappage height, and can there be hidden danger such as resistance wire frays, the manufacturing cost height.
Summary of the invention
The object of the present invention is to provide a kind of reliability height and the low resistance wire winding method of cost, low to overcome in the prior art reliability, defect of high cost.
Resistance wire winding method of the present invention adopts following steps:
A, preparation plain resistance wire and skeleton;
B, setting add the glue point, and this adds the front end that the glue point is positioned at plain resistance wire;
When C, skeleton moving, add glue to the skeleton surface by adding the glue point, simultaneously, the plain resistance wire wire feed, and towards the skeleton surface coiling that is added glue.
Among the described step B, described front end is meant the anterior position of plain resistance wire along the axial moving direction of skeleton.
Also comprise among the described step B: the rear end at described plain resistance wire is provided with hot spot, also comprises the steps D after the described step C:
D, described hot spot are to being wound in the lip-deep plain resistance wire of glue skeleton and corresponding glue carries out heating, drying.
Among the described step B, described rear end is meant the rear position of plain resistance wire along the axial moving direction of skeleton.
Described plain resistance wire keeps synchronously to the wire feed point and the described hot spot of skeleton.
Described plain resistance wire keeps synchronously to the wire feed point and the described glue point that adds of skeleton.
Among the described step C, the described glue point that adds evenly adds glue to the skeleton surface.
Beneficial effect of the present invention is: in the present invention, add the glue point by setting, add the front end that the glue point is positioned at plain resistance wire, during the skeleton moving, add glue by adding the glue point to the skeleton surface, simultaneously, the plain resistance wire wire feed, and, like this, objectively just forming towards the skeleton surface coiling that is added glue, earlier add glue on the skeleton surface, then, plain resistance wire is adding coiling on the skeleton surface of glue, and added glue (adhesive) can be fixed on plain resistance wire on the skeleton surface firmly, make the present invention obtain higher linearity, simultaneously, plain resistance wire part does not outwardly then have glue (adhesive), can not influence plain resistance wire (with brush plate) and electrically contact conduction property, and, technology of the present invention is comparatively simple, does not have the demand of special (expensive) for operation, and cost is low.
In the present invention, rear end at plain resistance wire is provided with hot spot, carries out heating, drying to being wound in the lip-deep plain resistance wire of glue skeleton with corresponding glue by hot spot, can be so that glue (adhesive) flash baking, can enhance productivity, further improve practicality of the present invention.
Among the present invention, the wire feed point, add glue point and hot spot keeps synchronously in the course of the work, can make technological operation of the present invention, effect stability, enhanced process flow process reproducibility further improves practicality of the present invention and reliability.
