The first driving motor 43 is used for controlling the clamping frame 42 to move along the guide rail 40, so that the clamping and positioning mechanism 5 and the capacitance detection mechanism 6 which are arranged on the vertical frame 45 and the bent rod 46 are conveniently controlled to be close to the capacitor 2, and the capacitor 2 is detected. When the sliding sleeve 51 is driven by the driving assembly 50 to move towards the capacitor 2, the push-pull rod 52 on the sliding sleeve 51 is inserted into the rubber block 53, and the ends of the rubber block 53 are close to each other due to the movement of the push-pull rod 52 in the opening groove 530, so that the clamping heads 54 at the ends of the rubber block 53 are close to each other, and the capacitor 2 is clamped. The telescopic cylinder 500 controls the first ferrule 501 to move along the mounting post 507 to drive the gear ring 503 and the second ferrule 506 on two sides of the sliding sleeve 51 to move, and the positioning post 5010 is arranged on one side of the gear ring 503 and the second ferrule 506 towards the sliding sleeve 51, so that the sliding sleeve 51 moves along the mounting post 507 when the telescopic cylinder 500 performs telescopic movement, and then the push-pull rod 52 is controlled to move, so that clamping or loosening operation of the rubber block 53 is completed. The driving gear 66 is controlled by the driving motor II 60 to be meshed with the gear ring 503, so that the gear ring 503 drives the second ferrule 506 to rotate around the mounting post 507, and then drives the L-shaped frame 69 to rotate around the outer surface of the capacitor 2, thereby realizing the form detection and the temperature detection of the outer surface of the capacitor 2. More specifically, in order to avoid the influence of the first ferrule 501 on the rotation of the gear ring 503, by arranging the clamping ring 504 on the side edge of the gear ring 503, the first connecting post 502 on the first ferrule 501 is matched with the clamping ring 504 through the clamping wheel 5020, so that the gear ring 503, the second ferrule 506 and the sliding sleeve 51 are reliably driven to axially move, and meanwhile, the rotation of the gear ring 503 and the second ferrule 506 is ensured, and the capacitance detection mechanism 6 is driven to perform the detection operation.
