A DEVICE TO ELEVATE LOADING PLATE IN THE HORIZONTAL-TYPE HANDLER

摘要

The present invention is based on the seating plate lifting device of the horizontal handler for lifting and lowering the seating plate exactly one step when classifying and unloading the defective product by the grade in the customer tray placed on the plurality of seating boards according to the test result after the completion of the device test. In this regard, the mechanical structure allows precise control of the position of the seat plate.;To this end, a plurality of cam grooves 3a are formed in the vertical direction in the same direction as the spacing between the plurality of seating plates 1, and the cam plate 3 fixed to the elevating plate 2 and an installation positioned close to the cam plate. It consists of a rotating plate (6) rotatably mounted on the plate (4), a cam rod (7) installed in the cam groove with a 180 ° phase difference on the rotating plate, and driving means for rotating the rotating plate at 180 ° intervals. By the mechanical operation according to the rotation of the rotating plate (6), the seating plate (1) fixed to the lifting plate (2) is lifted up by exactly one step, and the seating plate (1) falls even if a sudden power failure occurs during the operation of the equipment. This phenomenon is prevented beforehand.
