The relay detection apparatus according to claim 1, wherein: the detection mechanism comprises a U-shaped fixing frame (26), a second electric cylinder (27) is connected to the bottom of the U-shaped fixing frame (26), a lifting plate (28) is fixedly connected to the bottom end of the second electric cylinder (27), a detector (29) is connected to the top of the lifting plate (28), a detection loop bar (30) electrically connected with the detector (29) is fixedly arranged at the bottom end of the lifting plate (28), and the detection loop bar (30) is used for being sleeved at the position of a connecting pin of a relay to detect, and a conical guide shell (31) is fixedly connected to the bottom end of each detection loop bar (30).
6. A relay detection method, applicable to the relay detection apparatus according to any one of claims 1 to 5, characterized in that: the method comprises the following specific steps:
step one: firstly, placing a relay on the top of a first conveyor belt (3), and clamping the relay by an elastic clamping mechanism;
step two: the relay is placed on the top of the first conveyor belt (3), and the elastic clamping mechanism clamps the relay;
step three: when the relay moves to the detection position, the first conveying belt (3) and the second conveying belt (5) stop driving, so that the relay is accurately stopped under the detection mechanism, the detection mechanism is started, the detection mechanism moves downwards to surround and connect the positions of connecting pins of the relay, and the relay is detected;
step four: after the detection is finished, the detection mechanism resets, and the pushing mechanism is controlled to distinguish the pass and the fail of the relay, so that the pass is left on the first conveyor belt (3) on the second conveyor belt (5) when the fail moves;
step five: after the pushing mechanism is reset, the first conveying belt (3) and the second conveying belt (5) are started, the second conveying belt (5) drives the unqualified relay to move leftwards, the detected relay is conveyed out, and detection is completed.
