Then the mechanical arm 562 moves the welding rod on the positioning head 565 to the welding position to perform welding operations on the street lamp.

[0036] The second embodiment is different from the first embodiment in that:

[0037] See also Figure 4In the embodiment of the present invention, the feeding mechanism 566 includes an annular sleeve 5661 rotatably arranged on the outside of the column 561, and a plurality of placement grooves 5662 are equidistantly arranged on the outer edge of the annular sleeve 5661. The upper ends of the placement grooves 5662 extend to the upper part of the annular sleeve 5661, and the welding rods can just be stuck into the placement grooves 5662. An external gear 5663 is arranged on the outside of the lower end of the annular sleeve 5661. A rotating motor 5664 is installed on one side of the column 561 below the annular sleeve 5661. The output shaft of the rotating motor 5664 is connected to a driving gear 5665, and the driving gear 5665 is meshed with the external gear 5663.

[0038] See also Figure 5 In the embodiment of the present invention, the positioning head 565 includes a limiting cylinder 5651, an annular cavity 5652 is arranged inside the limiting cylinder 5651, an annular electromagnetic plate 5653 is arranged inside the annular cavity 5652, a plurality of arc-shaped spring pieces 5654 are arranged equidistantly on the inner wall of the limiting cylinder 5651, and a notch 5655 is arranged on the inner wall of the limiting cylinder 5651 at the inner side of the arc-shaped spring piece 5654, a magnetic block 5656 corresponding to the notch 5655 is arranged on the inner side of the arc-shaped spring piece 5654, a conductive block 5657 is arranged on the innermost side of the limiting cylinder 5651, and the conductive block 5657 is connected to the welding box through a wire so that it can transmit current to the welding rod, and a miniature camera is arranged on one end of the robotic arm 562 to facilitate viewing the specific welding position and welding condition.

[0039] See also Figure 5 In the embodiment of the present invention, the suction force of the annular electromagnetic plate 5653 on the magnetic block 5656 is greater than the elastic force of the arc-shaped spring piece 5654. When the arc-shaped spring piece 5654 is in the reset state, the diameter of the space formed between each arc-shaped spring piece 5654 is smaller than the outer diameter of the welding rod, so that the welding rod can be inserted into the limiting tube 5651, and each arc-shaped spring piece 5654 will support the welding rod to limit and fix the welding rod.

[0040] In the above scheme: when the welding rod is used up, the rotating cylinder 563 drives the electric push rod 564 to rotate, and the electric push rod 564 drives the positioning head 565 to rotate so that it is vertically downward. At the same time, under the movement of the mechanical arm 562, the positioning head 565 is made to correspond to the welding rod on the annular sleeve 5661, and then the power of the annular electromagnetic plate 5653 is turned on, and the annular electromagnetic plate 5653 adsorbs the magnetic blocks 5656 in each arc-shaped spring piece 5654, so that the spacing between each arc-shaped spring piece 5654 becomes larger, and the used welding rod in the limiting cylinder 5651 will fall down. After the welding rod falls down, the rotating motor 5664 drives the driving gear 5665 to rotate, and the driving gear 5665 drives the outer gear 5663 meshing with it to rotate, and the outer gear 5663 drives the annular sleeve 5661 rotates to make the corresponding welding rod move to the bottom of the positioning head 565, and then the electric push rod 564 drives the positioning head 565 to move downward, so that the upper end of the welding rod is inserted into the limiting cylinder 5651 and contacts with the conductive block 5657. After the contact, the power of the annular electromagnetic plate 5653 is turned off, and the annular electromagnetic plate 5653 will not generate suction to the magnetic block 5656. Under the elasticity of the arc-shaped spring pieces 5654, each arc-shaped spring piece 5654 will reset to support the welding rod in the limiting cylinder 5651, thereby fixing the welding rod. Finally, the rotating cylinder 563 drives the electric push rod 564 to rotate, and the electric push rod 564 drives the positioning head 565 to rotate, so that the installed welding rod is separated from the placement groove 5662 on the annular sleeve 5661, so as to facilitate the welding operation of the smart street lamp.

[0041] Working principle: Combine the annular body 1 41 and the annular body 2 42, and put the street light pole on it to fix the base 1 on the ground, then use the screw to connect the annular body 1 41 and the annular body 2 42 together with the connecting block 43, then the lifting servo motor 2 drives the screw 3 to rotate, the screw 3 drives the threaded sleeve 44 to move, and then can drive the moving seat 4 to move longitudinally, the moving seat 4 drives the welding mechanism 5 to move to the welding height, after reaching the welding height, drive the servo motor 54 to drive the main gear 55 to rotate Since the main gear 55 is meshed with the arc-shaped rack 46, the main gear 55 rotates to make the welding mechanism 5 rotate around the moving seat 4, so that the welding machine 56 moves to the welding direction, and the displacement servo motor 512 drives the threaded rod 511 to rotate, and the threaded rod 511 drives the moving block 513 to move, and the convex shaft 514 on the moving block 513 drives the column 561 to move, and the position of the welding machine 56 is adjusted. Then, the mechanical arm 562 moves the welding rod on the positioning head 565 to the welding position, and the street lamp is welded;

[0042] When the welding rod is used up, the rotary cylinder 563 drives the electric push rod 564 to rotate, and the electric push rod 564 drives the positioning head 565 to rotate so that it is vertically downward. At the same time, under the movement of the mechanical arm 562, the positioning head 565 is aligned with the welding rod on the annular sleeve 5661, and then the power of the annular electromagnetic plate 5653 is turned on. The annular electromagnetic plate 5653 absorbs the magnetic blocks 5656 in each arc-shaped spring piece 5654, so that the distance between each arc-shaped spring piece 5654 becomes larger, and the used welding rod in the limiting cylinder 5651 will fall down;

[0043] After the welding rod falls, the rotating motor 5664 drives the driving gear 5665 to rotate, and the driving gear 5665 drives the outer gear 5663 meshing with it to rotate, and the outer gear 5663 drives the annular sleeve 5661 to rotate, so that the corresponding welding rod moves to the bottom of the positioning head 565, and then the electric push rod 564 drives the positioning head 565 to move downward, so that the upper end of the welding rod is inserted into the limiting cylinder 5651 and contacts the conductive block 5657. After the contact, the power supply of the annular electromagnetic plate 5653 is turned off. The annular electromagnetic plate 5653 will not generate suction to the magnetic block 5656. Under the elasticity of the arc-shaped spring pieces 5654, each arc-shaped spring piece 5654 will reset, and support the welding rod in the limiting cylinder 5651, thereby fixing the welding rod. Finally, the rotating cylinder 563 drives the electric push rod 564 to rotate, and the electric push rod 564 drives the positioning head 565 to rotate, so that the installed welding rod is separated from the placement groove 5662 on the annular sleeve 5661, so as to facilitate the welding operation of the smart street lamp.
