The resistance value continuous testing device includes base, conveyor belt, display device, gear, motor, bracket, fixing plate, movable plate and resistance measuring module. The display device, the motor, the conveyor belt, and the resistance measuring module are all arranged on the base, the fixed plate is arranged on the base through the bracket, the gear is connected with the fixed plate through the movable plate, and the motor is connected to the gear shaft of the gear. The gear is set above the conveyor belt. The metal contact plate is arranged in the gear groove, and the metal contact plate is arranged in pairs at both ends of the gear groove. The metal contact plate is electrically connected with the resistance measuring module, and the resistance measuring module 9 is electrically connected with the display device 3. The resistance measurement module includes a LM358 RV circuit, used to measure the resistance value.
The advantages of the resistance value continuous test device are obvious, and the resistance test equipment also comprises the key of on-off keying and measuring rotating speed key, which are connected to motor. The on-off keying controls the start and end of the device. Speed key regulates the rotating speed so as to control the test speed. These devices can be used to test large quantities of resistors effectively, which can provide more accuracy for resistance production and greatly improve the accuracy of resistance leaving the factory. These devices can be used to test large quantities of resistors effectively, which can improve the accuracy for resistance production and greatly upgrade the accuracy of resistance leaving the factory.
