4, when the output of the rubber magnet 6 formed on the surface of the encoder ring 4 is to be measured, the rubber magnet 6 is rotated in a state in which the encoder ring 4 is rotated, The output of the rubber magnet 6 is measured so that the output of the rubber magnet 6 is measured.

Korean Patent No. 10-0955630 (Mar. 23, 2010) discloses a method for automating encoder sealing, inspecting and assembling processes and an automation method for inspecting such conventional encoder ring rubber magnet output. The apparatus for automating the encoder seal magnetizing and inspecting and assembling process comprises an inner iron feeder and an outer iron feeder, wherein the inner iron feeder comprises an inner iron supply rotating plate, an inner iron supply lifter for supplying outer iron from the inner iron supplying rotary plate, And an inner iron inspection part for inspecting a magnetized state of an inferior rubber magnet which is transferred from the magnetized part and the magnetized part of the supplied rubber magnet to the inner iron, and the outer iron supply part comprises a outer iron supply rotating plate, A first balance for measuring the weight of the outer iron supplied by the outer iron supply lifter, a Christ aspirating the grease applied to the outer iron conveyed from the first balance, The second balance, the second balance, and the outer rail and the inner rail transferred from the inner rail inspection portion are assembled And an assembly inspection section for inspecting the assembly state of the inner and outer rings assembled in the assembly section and the assembly section.

However, in the above conventional technology, since the sensor for measuring the output of the rubber magnet formed on the surface of the base metal is formed as a single sensor, the measurement of the output of the rubber magnet is measured in a single channel, There is a difficult limit, and since the height adjustment of the sensor is impossible, there is a limit in which the difference in output according to the measurement distance can not be measured. As a result, it is difficult to precisely measure the rubber magnet output.
