A tray transfer apparatus for test handlers is provided to reduce manufacturing cost by maintaining durability irrespective of conditions of a test chamber using an external cylinder and an external motor. A tray transfer apparatus for test handlers includes a moving member, a holding member(510), a first power source, a first power delivering member(530), a second power source, and a second power delivering member(550). The holding member moved with movement of the moving member includes a holding pin for holding a test tray based on the movement. The first power source implemented independently from the movement of the holding member supplies power for front and back movement of the holding member. The first power delivering member delivers power from the first power source to the moving member. The second power source supplies power for left and right movement of the holding member. The second power delivering member delivers power from the first power source to the moving member. The first power delivering member includes a rotation bar, which is rotated under control of the first power source, and link members for converting the rotation of the rotation bar into the movement of the holding member. |
