Conveyance apparatus including variable jig and driving method thereof

A conveyance apparatus including a variable jig, the conveyance apparatus comprising:

• a transport unit including a transfer belt extending from a loading position to an unloading position of works, the transport unit being a movement path for the works;
• a variable jig module disposed with respect to a position, where the works stop, in the movement path to support the works, the variable jig module being a variable jig that varies a supporting base, based on shapes of the works;
• a sensing unit disposed outside the transfer belt with respect to the variable jig module to measure a movement or position of the works;
• an image processing unit configured to perform image processing on the works transported by the transfer belt to generate image information;
• and
• a controller electrically connected to the variable jig module to control an operation of the variable jig module,
• wherein the controller controls an operation of a motor of the variable jig module to raise a plurality of support pin parts of the variable jig module with a driving force of the motor, and to stop the raising of the plurality of support pin parts according to a pressure measurement value of a pressure sensor of each of the plurality of support pin parts when each of the plurality of support pin parts contacts a bottom of the works, and
• wherein the controller checks whether the works are located at a predetermined position by matching-comparing a position of the works on the variable jig module with a position included in a design drawing by using the image information and previously prepared design drawing information about the works.
