Substrate pickup tool, substrate assembly station and substrate installation method

A substrate assembly station, used to install a substrate having a through hole onto an assembling part, the substrate assembly station comprising:

• a support device, comprising a support surface and a carrier, wherein the support surface and the carrier are used to support the substrate and the assembling part, respectively;
• a transfer mechanism, disposed on the support device and provided with a movable portion movable relative to the support device;
• and
• a substrate pickup tool, comprising:
• a gripper frame, disposed on the movable portion of the transfer mechanism;
• and
• a flexible gripper, comprising an annular mount portion and a plurality of claw portions, wherein the annular mount portion is mounted on the gripper frame, the plurality of claw portions are connected to the annular mount portion and each has an outer contact surface, the flexible gripper is used to correspond to the through hole of the substrate;
• wherein the flexible gripper is provided with a chamber which is surrounded and formed by an inner wall surface of the flexible gripper;
• a central axis of the flexible gripper passes through the chamber, the annular mount portion, and a pipe joint;
• and the chamber is configured for gas to pass therethrough to force the plurality of claw portions to move relative to the annular mount portion and press against an inner wall surface of the through hole via the outer contact surface of each of the plurality of claw portions for picking up the substrate and moving the substrate onto the assembling part via the transfer mechanism,
• wherein the annular mount portion has an end surface facing away from the chamber in an axial direction, and the plurality of claw portions are entirely located outside the chamber and connected to the end surface of the annular mount portion.

A substrate installation method, comprising:

• holding a substrate via at least one outer contact surface of a flexible gripper of a substrate pickup tool;
• lifting up the substrate pickup tool;
• and
• moving the substrate pickup tool to stack the substrate onto an assembling part;
• wherein the step of holding the substrate via the at least one outer contact surface of the flexible gripper of the substrate pickup tool comprises:
• inserting the flexible gripper of the substrate pickup tool into a through hole of the substrate;
• and
• allowing gas to pass through a chamber of the flexible gripper to expand a plurality of claw portions of the flexible gripper toward an inner wall surface of the through hole to press against the inner wall surface of the through hole via outer contact surfaces of the plurality of claw portions for holding the substrate, wherein a central axis of the flexible gripper passes through the chamber of the flexible gripper, an annular mount portion of the flexible gripper, and a pipe joint,
• wherein the annular mount portion has an end surface facing away from the chamber in an axial direction, and the plurality of claw portions are entirely located outside the chamber and connected to the end surface of the annular mount portion.
