Description
Technical Field
The utility model relates to the technical field of resistor production, in particular to a resistor full-inspection machine.
Background
The resistor is a current limiting element that, when connected in a circuit, limits the amount of current that can pass through the branch to which it is connected. If a resistor has infinite or large resistance, the loop connecting the resistors in series can be regarded as an open circuit, and the current is zero; if the resistance of a resistor is close to zero ohms, the resistor has no blocking effect on the current, the loop parallel to such resistor is short-circuited, and the current is infinite. Both of these conditions lead to the fact that the resistor is difficult to perform and, in the severe case, can cause damage to the electrical equipment.
In order to avoid the loss of the resistor to the user, the resistor manufacturer can detect the resistance value of the resistor before the resistor leaves the factory, and the defective product detection is avoided. Because the resistors have large yield and small volume, in order to improve the detection efficiency and reduce the labor cost, generally, the resistors can only be subjected to sampling inspection, namely, some samples are extracted from a plurality of resistors of one batch for detection, if the sampling inspection result of the samples is normal, the batch is judged to be normal, and if the samples are subjected to sampling inspection to obtain defective products, the resistors of the batch are subjected to full inspection. Nevertheless, the objective existence of sampling errors may result in some defective products not being detected, thereby causing the defective products to flow to the market.
