Abstract

A welding device includes a frame body, a first movable module, a second movable module, a third movable module, and a welding module. The first movable module is installed on the frame body and movable in a first horizontal direction. The second movable module is installed on the first movable module and movable in a second horizontal direction perpendicular to the first horizontal direction. The third movable module is installed on the second movable module and movable in a vertical direction perpendicular to the first and second horizontal directions. The welding module is installed on the third movable module and movable together with the first, second, and third movable modules. The welding module is suspended outside the frame body, and the first movable module is provided in an inner chamber of the frame body to reduce the distance between the welding module and the frame body.

First claim

5 . The welding device according to claim 3 , wherein the second movable module comprises:
an installation frame; a second slide rail extending along the second horizontal direction and fixed to the installation frame; and a second slider slidably installed on the second slide rail and movable in the second horizontal direction, the installation frame is fixed to the horizontal mounting plate, so that the second movable module is movable along the first horizontal direction with the horizontal mounting plate.

6 . The welding device according to claim 5 , wherein the second movable module further comprises a second driving device installed on the installation frame and connected to the second slider, the second driving device is adapted to drive the second slider to move in the second horizontal direction.

7 . The welding device according to claim 6 , wherein the second driving device comprises:
a second lead screw rotatably installed on the installation frame; a second nut fixed to the second slider and threaded to the second lead screw; and a second motor installed on the installation frame and having an output shaft connected to the second lead screw, when the second motor drives the second lead screw to rotate, the second lead screw drives the second nut and the second slider to move together in the second horizontal direction.

8 . The welding device according to claim 1 , wherein when the welding device performs welding operations, the second movable module is partially or completely moved into the inner chamber of the frame body and further reduces the distance between the welding module and the frame body.

9 . The welding device according to claim 5 , wherein the third movable module comprises:
a vertical mounting plate; a third slide rail extending in the vertical direction and fixed to the vertical mounting plate; a third slider slidably installed on the third slide rail and movable in the vertical direction; and a mounting bracket fixed to the third slider and movable along the vertical direction with the third slider.

10 . The welding device according to claim 9 , wherein the welding module is installed on the mounting bracket and is movable along the vertical direction with the mounting bracket.

11 . The welding device according to claim 10 , wherein the vertical mounting plate is fixed to the second slider, so that the third movable module can move along the second horizontal direction with the second slider.

12 . The welding device according to claim 11 , wherein the third movable module further comprises a third driving device installed on the vertical mounting plate and connected to the third slider, the third driving device is adapted to drive the third slider to move in the vertical direction.

13 . The welding device according to claim 12 , wherein the third driving device comprises:
