The invention discloses a feeding device for the overload detection of a no-lead resistor, and the device comprises a support. The support comprises four symmetric supporting legs, and a first cross beam is connected between two supporting legs at one side of a table plate in the longitudinal direction. A second cross beam is connected between two supporting legs at the other side of the table plate in the longitudinal direction, and lateral guide rods are connected between two supporting legs of the table plate in the lateral direction. A transmission plate is connected between the two lateral guide rods, and is provided with a group of fixed plates, wherein each fixed plate is connected with a feeding pipe, and the feeding pipe is cooperatively connected with a feeding hopper. The transmission plate is also connected with a screw nut, and the first cross beam is provided with a motor. The motor is connected with the screw nut through a screw, and an end part of the screw is connectedto a second cross beam through a bearing. The advantages of the device are that the device can achieve the batch feeding of resistors, saves work and time, improves the production efficiency and machining quality, is convenient to use, is convenient to operate, and is suitable for batch production.
