Background

Chip resistors are a commonly used resistive device in electronic components, and are usually made of a ceramic or dielectric substrate with a resistive layer, and have a rectangular shape, a flat surface and two electrode leads. The existing chip resistor is usually required to be tested by testing methods such as resistance, appearance, temperature measurement, withstand voltage and the like after production is finished, and can be applied to the production of electronic products after the test is qualified, however, when the existing chip resistor detection device is used for testing the resistor, the operation steps are complicated, the function of the test device is single, the detection efficiency of the chip resistor cannot be improved, and with the development of technology, a large amount of optimization is performed on the chip resistor detection device by technicians in related fields;

The Chinese patent publication No. CN216524061U discloses a bad particle detection device in a chip resistor: when the movable block is used, when the movable block is detected, the resistor is placed on the upper surface of the supporting plate, the rotating handle is rotated to drive the threaded rod to rotate in the groove, the movable block is driven to move through the threaded hole, the limiting rod limits the sliding direction of the movable block through the limiting hole, the movable block slides along the outer surfaces of two ends of the threaded rod to the middle position of the threaded rod, the movable block moves to drive the clamping plate to move, the connecting wire extends, meanwhile, the fixing frame and the detecting plate are driven to move, after the detecting plate contacts the chip resistor, the chip resistor is detected, the fixing frame is fixed, the fixing frame is close to the clamping plate, the fixing frame is aligned to the inside of the fixing block, then the fixing frame is moved, the fixing frame is sleeved on the outer surface of the clamping plate, meanwhile, after the fixing frame slides into the inside of the fixing block, the sliding direction of the fixing frame is limited, then the fixing bolt is screwed, the fixing bolt rotates on the outer surface of the fixing frame, after the fixing bolt rotates into the inside of the fixing hole, the fixing bolt is connected with the clamping plate, and the fixing frame is fixed at the same time, and the fixing frame is completed.

However, the poor particle detection device in the chip resistor has some disadvantages in the practical use process:

1. when the device detects the resistor, the resistor needs to be manually placed on the testing device, and when a plurality of resistors are tested, the testing efficiency of the resistor becomes very low.

2. According to the device, when the resistor is clamped, the resistor is fixed by manually screwing the bolt, after the test is finished, the resistor is taken down by manually screwing the bolt, the operation steps are complex, and the test efficiency is further reduced.

3. In the testing process of the resistor, the testing device has a single testing function, and can only test specific types of resistors, so that the applicability of the resistor is greatly reduced.

Therefore, under the above stated viewpoints, the conventional chip resistor detection device has room for improvement.
