If the reactor has cracks, the electrode material is prone to leakage after heat treatment, and even the reactor may burst and break, affecting the processing of the electrode material. Therefore, the reactor needs to be subjected to crack visual detection.

[0025] The working principle of the electrode material reactor crack visual detection device is as follows: first, the reactor 66 to be detected is clamped on the supporting seat 65 with the opening upward, then the servo motor 61 is controlled to start and drive the pinion 62 to rotate, the pinion 62 drives the lifting cylinder 64 and the supporting seat 65 on the large gear 63 to rotate linearly, the supporting seat 65 drives the reactor 66 to rotate linearly, at the same time, the large gear 63 drives the three sets of differential gears 112 on the reciprocating lead screws 113 to rotate synchronously, the three reciprocating lead screws 113 drive the connecting pieces 115 on the three sets of lead screw sleeves 114 to slide up and down in the vertical groove 111, the three sets of connecting pieces 115 drive the industrial cameras 4 in the ring design on the arc-shaped frame 116 to conduct comprehensive visual monitoring on the cracks of the reactor 66 in the linear rotary displacement state, after the reactor 66 completes the crack visual detection in the rotary displacement mode, the servo motor 61 is controlled to pause, the first electromagnet 75 is energized through the first circuit breaker 74 to electromagnetically adsorb the reactor 66 in the initial position on the first permanent magnet 76, then the lifting cylinder 64 drives the supporting seat 65 to move downward and separate from the bottom of the reactor 66, at this time, the servo motor 61 is controlled to restart and drive the pinion 62 to rotate through the main gear 72 on the rotating rod 71, the first electromagnet 75 and the first permanent magnet 76 are electromagnetically adsorbed to drive the reactor 66 to overturn, similarly, the large gear 63 drives the three sets of differential gears 112 on the reciprocating lead screws 113 to rotate synchronously again, then the industrial cameras 4 in the ring design conduct comprehensive visual monitoring on the cracks of the reactor 66 in the overturning displacement state; After the reactor 66 completes the crack visual detection in the rotary and overturning states, the servo motor 61 is controlled to pause, the lifting cylinder 64 drives the supporting seat 65 to move upward to limit the reactor 66 in the initial position, then the first electromagnet 75 is de-energized through the first circuit breaker 74 to release the electromagnetic adsorption of the reactor 66 on the first permanent magnet 76, at the same time, the second electromagnet 19 is de-energized through the second circuit breaker 18 to release the electromagnetic adsorption of the blocking cover 86 on the second permanent magnet 20, the electric push rod 14 is controlled to start and drive the pinion 62 to move downward and engage with the meshing part of the side gear 91 through the pinion 62, then the servo motor 61 is controlled to restart and drive the pinion 62, the pinion 62, the side gear 91 and the pinion 73 engaged in position to rotate successively, the pinion 62 drives the threaded cylinder 83 on the threaded rod 82 to move downward, the threaded cylinder 83 drives the blocking cover 86 on the damping sliding head 85 through the extrusion rod 84 to move downward toward the opening direction of the reactor 66 in the initial state, until the blocking cover 86 is clamped at the opening of the reactor 66, and the compression spring 17 is extruded, then the blocking cover 86 blocks the reactor 66 to maintain a sealed environment; Meanwhile, the side gear 91 drives the piston 94 on the connecting rod 93 to reciprocate in the piston cylinder 5 through the cam 92, and the heated oil in the oil storage pot 22 heated by the heating base 23 is extracted through the negative pressure pipe 96 on the five-way valve 95, and the oil temperature passing through the five-way valve 95 is monitored in real time by the temperature sensor 24, and then the extracted hot oil passes through the two groups of communication ports 101, the threaded hose 103 and the rotating port 102 in turn to reach the telescopic hose 104 pulled down by the two follow-up blocking covers 86, and then is uniformly injected into the reactor 66 in the blocking state through the fine hole 106 at the bottom of the extrusion seat 105 designed in a hollow structure, until the hot oil is filled in place, and the reactor 66 is blocked by the blocking cover 86, and at the same time that the extrusion seat 105 fills the hot oil through the fine hole 106, the threaded cylinder 83 also drives the extrusion seat 105 to continue to move downward into the reactor 66 through the extrusion rod 84, and applies a downward pressure to the filled hot oil, and at the same time that the hot oil conducts heat to the reactor 66, the extrusion stress generated by the downward pressure of the extrusion seat 105 forces the hot oil to extrude the reactor 66, expands the potential cracks in the reactor 66, and also rotates the reactor 66 in the blocking state at the rotating slot 21 in the blocking cover 86 through the support seat 65, and the industrial camera 4 designed in a ring type on the arc-shaped frame 116 is driven by the three groups of connecting pieces 115 to comprehensively monitor the cracks of the reactor 66 in the hot oil bath and the extrusion stress state, and the hot oil leaks through the expanded cracks, and if the reactor 66 still does not leak after the hot oil is extruded, and the above-mentioned transposition and visual detection of the turned cracks are all normal, then the reactor 66 is a qualified product.
