Gantry motion platform

A gantry motion platform, comprising:

• a base;
• a first transmission mechanism mounted on the base, wherein the first transmission mechanism comprises two first sliding rails, at least one first sliding block, and a first driving member, and the two first sliding rails extend along a first direction and are mounted on the base at intervals in a second direction, the at least one first sliding block is slidably disposed on the two first sliding rails;
• a second transmission mechanism mounted on the at least one first sliding block, the first driving member being capable of driving the second transmission mechanism to move along the first direction;
• and
• a working platform mounted on the second transmission mechanism, the second transmission mechanism being capable of driving the working platform to move along the second direction,
• wherein an included angle is defined between the first direction and the second direction,
• the second transmission mechanism comprises a support beam, a second sliding rail, a second sliding block, and a second driving member;
• the support beam is fixed to the first sliding block;
• the second sliding rail is fixed to the support beam;
• the second sliding block is slidably connected to the second sliding rail;
• and
• the second driving member is fixed to the support beam and configured to drive the second sliding block to move along the second direction,
• wherein the first driving member comprises a seat, a ball screw, a ball screw nut, and a driving source;
• the seat is directly disposed on the base and located at a center position between the two first sliding rails;
• the driving source is in transmission connection with the ball screw nut and is configured for driving the ball screw nut to rotate;
• the ball screw nut is disposed on the seat and screwed to one end of the ball screw;
• another end of the ball screw is directly connected and directly fixed to the supporting beam of the second transmission mechanism, the ball screw is parallel to the two first sliding rails, and when the screw nut rotates, the ball screw is driven to move along the first direction, so that the second transmission mechanism is capable of driving the working platform to move along the first direction.
