Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a transformer turntable mechanism and a visual inspection device. Background Technology

[0002] A transformer is an electrical component assembled from an iron core and coil windings. After the transformer is manufactured, it is generally necessary to perform visual inspection and performance testing to determine whether the production meets the standards.

[0003] Regarding the transformer appearance inspection process, the existing technology generally adopts manual inspection or automated equipment inspection to inspect the appearance of transformers. Due to the defects of low efficiency, high labor intensity of workers, and large inspection error, this inspection method has been basically phased out.

[0004] Existing automated inspection equipment typically places the transformer on a rotating turntable to drive the transformer to rotate, and then uses a vision inspection mechanism to perform automated appearance inspection on the rotating transformer. Although this inspection method can effectively improve the efficiency and accuracy of transformer appearance inspection, the equipment still has a low appearance inspection efficiency because each transformer needs to be stopped for loading and unloading after appearance inspection.

Further, the first turntable drive assembly 130 includes a first turntable drive unit 131 for providing the rotational power source for the first turntable assembly 110, and a first turntable transmission unit 132 connected between the first turntable drive unit 131 and the first turntable linkage unit 112; wherein the first turntable transmission unit 132 drives the first turntable assembly 110 to rotate under the power of the first turntable drive unit 131.
