The utility model discloses an LED
bulb testing device which comprises a conveying belt, a
workbench, a plc controller and a man-
machine interaction panel, the
workbench is provided with a testing device, the testing device comprises a supporting frame, a lifting cylinder, a rotating cylinder, a conductive cap, a photosensitive sensor, an
infrared sensor and a limiting
assembly, and the conveying belt drives a code disc to move in a stepping mode. The testing process is automatically started in cooperation with an
infrared sensor, efficient and
automatic testing is achieved, manual intervention is reduced, and
continuous operation can be achieved. The limiting
assembly adopts a bidirectional screw rod and other structures, the LED
bulb is bidirectionally and symmetrically fixed, and a spring rod and a rubber
gasket not only ensure
stable fixation, but also can protect the
bulb, adapt to different sizes, and prevent shaking during testing to ensure accurate results. The lifting cylinder, the rotating cylinder and the conductive cap cooperatively simulate real
assembly and
electrification, so that the test is closer to an
actual use scene.
