Welding information providing apparatus

1 . A welding information providing apparatus comprising:

a main body provided to be worn by a user;

a display unit arranged in the main body and including a display for displaying a welding image to the user;

a primary lens member arranged on a path through which the welding image provided from the display travels and including a convex surface for adjusting a size of the welding image to allow the welding image to reach both eyes of the user, wherein the primary lens member is rotatable about an axis located within the primary lens member and extending between a first end of the primary lens member and a second end of the primary lens member and wherein a surface of the primary lens member facing the display is adjustable in angle with respect to the display;

at least one camera mounted on an outer side of the main body and configured to obtain a welding image frame with respect to a welding operation;

a processor configured to control the display to display the welding image generated based on the welding image frame,

a front body protruding from the main body, in which the display unit and the primary lens member are arranged, wherein the front body is configured to maintain a state in which the display unit and the primary lens member are spaced apart from each other such that the display unit and the primary lens member are arranged along an imaginary center line passing through a center of the display unit, and

a lens frame coupled to the front body, wherein the lens frame is configured to support the primary lens member and rotate the primary lens member relative to the front body about the axis.

2 . The welding information providing apparatus of claim 1 , wherein

the imaginary center line is between both eyes of the user.

3 . The welding information providing apparatus of claim 2 , wherein

the imaginary center line passes through the primary lens member.

4 . The welding information providing apparatus of claim 2 , wherein

the primary lens member includes two convex surfaces corresponding to a left eye and a right eye of the user, respectively.

5 . The welding information providing apparatus of claim 4 , wherein,

when the primary lens member includes two convex surfaces, the primary lens member includes a left-eye lens corresponding to the left eye of the user and a right-eye lens corresponding to the right eye of the user, which are separable from each other.

6 . The welding information providing apparatus of claim 1 , wherein

the primary lens member is movable to adjust a distance between the primary lens member and the display.

7 . The welding information providing apparatus of claim 1 , wherein

the display unit is movable to adjust a distance between the primary lens member and the display.

8 . The welding information providing apparatus of claim 1 , wherein

an angle of the display unit is adjustable to cause the display to be inclined with respect to the primary lens member.

9 . The welding information providing apparatus of claim 1 , wherein

the front body is installed in the main body to open and close one region of the main body.

10 . The welding information providing apparatus of claim 9 ,

wherein the lens frame is installed in the front body to open and close one region of the front body.

11 . The welding information providing apparatus of claim 1 , wherein:

the path is defined from the display to an interior volume defined by the main body;

in a first state, the primary lens member is positioned along the path; and

in a second state, the path is unobstructed by the primary lens member.

12 . The welding information providing apparatus of claim 11 , wherein the primary lens member is movable between the first state and the second state.

13 . The welding information providing apparatus of claim 12 , wherein the primary lens member is rotatable between the first state and the second state.

14 . The welding information providing apparatus of claim 1 , wherein the display unit is rotatable about an axis between a first end of the display unit and a second end of the display unit.
