Description
Technical Field
The invention relates to the technical field of resistor production and manufacturing, in particular to full-automatic intelligent aging equipment for a resistor porcelain rod.
Background
A Resistor (Resistor) is commonly referred to as a Resistor and is a current limiting element. The resistance of the resistor is generally fixed, and the resistor is connected in a circuit to limit the current through the branch to which it is connected. The resistor is of various kinds and can be classified into:
a. wire wound resistor: the resistor is made up by winding a resistor wire on an insulating skeleton (porcelain rod, etc.), and is coated with a heat-resistant glaze insulating layer or insulating paint. The winding resistor has lower temperature coefficient, high resistance precision, good stability, heat resistance and corrosion resistance, is mainly used as a precise high-power resistor, and has the defects of large inductance and poor high-frequency performance.
b. Carbon synthesis resistor: is made up by pressing carbon and synthetic plastics.
c. Carbon film resistor: the ceramic tube is coated with a layer of carbon, and crystalline carbon is deposited on the ceramic rod framework to prepare the ceramic rod. The carbon film resistor has the advantages of low cost, stable performance, wide resistance range, low temperature coefficient and voltage coefficient, and is the most widely applied resistor at present.
d. Metal film resistor: the ceramic tube is coated with a layer of metal, and the alloy material is evaporated on the surface of the ceramic rod framework by a vacuum evaporation method. The metal film resistor has higher precision, better stability and less noise and temp coefficient than carbon film resistor. Is widely used in instruments and communication equipment.
e. Metal oxide film resistor: a layer of tin oxide is plated on the porcelain tube, and a layer of metal oxide is deposited on the insulating rod (porcelain rod, etc.). Since the catalyst is an oxide, the catalyst is stable at high temperature, resistant to thermal shock and strong in loading capacity.
The production process of the resistor generally comprises: pressing and forming a porcelain rod matrix, coating a porcelain rod film or winding, pressing a cap, sorting, grooving, welding a lead, coating, packaging and marking, and warehousing a product. In order to improve the quality of the product, aging treatment is carried out after the cap pressing process, and then sorting is carried out; the aging treatment comprises the processes of temperature circulation, short-time overload, power aging and the like, defective products can be removed, the stabilization time of the resistor is shortened, and the resistor with stability is further optimized. Taking the example of a precision foil resistor, the aging process contributes to its increased stability as follows: temperature circulation, namely, circulating exercise foil and contact points to release internal stress, and not reducing initial bonding strength; short-time overload, eliminating existing hot spots; and (3) power aging, loading power in a designated time period, and eliminating the active period of the change of the resistance value of the load curve.
