Device and method for intelligently detecting wiring state of multi-gear rotary switch

Abstract

The invention discloses a device and a method for intelligently detecting the wiring state of a multi-gear rotary switch. The device is composed of a power module, a motion module, a detection controlmodule and an indication module, wherein the power module supplies power to all other modules; the motion module is connected with a rotary switch knob, free switching is gears is realized through motor motion, and the rotary switch returns to a neutral gear position after detection is over; the detection control module controls motion of a stepping motor in the motion module, after rotary switchinformation is detected, the rotary switch information is compared with the motion state of the stepping motor to judge whether the rotary switch has a problem or not, and obtained information is transmitted to the indication module; and the indication module outputs a result of whether the rotary switch condition is good or not through an indicator light and a buzzer. Through the device and themethod, the wiring state of the rotary switch can be automatically detected, and a quality inspector can be intelligently prompted of switch quality information; and the device and the method have theadvantages that reliability is high, operation is convenient, and cost is low.

Description

technical field [0001] The invention relates to a rotary switch detection technology, in particular to a device and method for intelligently detecting the wiring status of a multi-position rotary switch. Background technique [0002] At present, the application market of multi-position rotary switches is relatively broad, the market demand is also increasing, and the output of multi-position rotary switches continues to increase. At the same time of mass production, the number of defective products has also increased. The main problems of defective products of multi-position rotary switches are reflected in the two situations of wiring misalignment and disconnection. Undiscovered defective products have major safety hazards. , if it is not detected before leaving the factory, once it leaves the factory, it will be very dangerous to the user. [0003] At present, the detection of the rotary switch mainly relies on the quality inspector to connect all the outlets of the switc...

Problems solved by technology

At the same time of mass production, the number of defective products has also increased. The main problems of defective products of multi-position rotary switches are reflected in the two situations of wiring misalignment and disconnection. Undiscovered defective products have major safety hazards , if it is not detected before leaving the factory, once it leaves the factory, it will be very dangerous for the user

[0003] At present, the detection of the rotary switch mainly relies on the quality inspector to connect all the outlets of the switch to the LED display lights, and connect the DC power to the input of the switching power supply, rotate the switch in turn, and observe the brightness of the LED lights each time. This detection method is artificially leaked. It is more likely to be inspected, and each rotary switch has to be observed many times, which is not a small workload for quality inspectors
