The second rotating shaft 603 and the first rotating shaft 602 are rotatably connected on both sides of the rear side of the top of the bottom plate 601. The second rotating shaft 603 and the second rotating shaft are rotatably connected. The first gear 604 and the second gear 605 are fixedly sleeved on the upper part of 603, and the outer teeth of the first gear 604 are meshed with the outer teeth of the second gear 605. A rack 606 is fixedly installed on the rear side of the support seat 5, and the outer teeth of the rack 606 are meshed with the outer teeth of the second gear 605. A square socket 607 is opened on the Y-axis conveying mechanism 2, and a protective cover 608 is fixedly sleeved on the outer sides of the second rotating shaft 603 and the first rotating shaft 602, and a protective top 609 is fixedly installed on the top of the protective cover 608. A rack 606 is provided on the rear side of the support seat 5. When the welding rod 8 and the welding head 9 are not needed, the X-axis conveying mechanism 3 drives the support seat 5 to drive the rack 606 to move backward. Since the rack 606 is meshed with the second gear 605, and the second gear 605 is meshed and connected with the first gear 604, the first rotating shaft 602 and the second rotating shaft 603 are driven to rotate in opposite directions, so that the protective covers 608 on the second rotating shaft 603 and the first rotating shaft 602 rotate toward the direction of the rack 606 respectively. When the welding rod 8 and the welding head 9 move to above the bottom plate 601, the protective cover 608 is used to cover the welding rod 8 and the welding head 9 to protect the welding rod 8 and the welding head 9 and avoid damage to the welding rod 8 and the welding head 9 caused by foreign objects.

[0031] In one embodiment of the present invention, a wear display assembly 7 is provided on the top of the bottom plate 601. The wear display assembly 7 includes a telescopic rod 701, a spring 702, a pressure plate seat 703 and a display rod 704. The telescopic rod 701 is fixedly installed on one side of the top of the bottom plate 601. The pressure plate seat 703 is fixedly installed on the top of the telescopic rod 701. The spring 702 is movably sleeved on the outer side of the telescopic rod 701. The two ends of the spring 702 are respectively fixedly installed on the top of the bottom plate 601 and the bottom of the pressure plate seat 703. The display rod 704 is fixedly installed on the bottom of the pressure plate seat 703. By providing the wear display assembly 7 on the bottom plate 601, when the welding head 9 moves to a position in contact with the pressure plate seat 703, the pressure plate seat 703 is pressed downward, driving the display rod 704 and the scale 705 to move downward. By observing the length of the scale 705 extending from the bottom of the bottom plate 601, the length of the welding head 9 can be known. When the welding head 9 is worn and shortened, it can be found in time, so as to replace the welding head 9 that is worn and cannot be used in time.

[0032] In one embodiment of the present invention, the wear display assembly 7 further includes a scale 705, and the scale 705 is provided on the front side of the display rod 704. The scale 705 is provided on the display rod 704 to facilitate the staff to observe the remaining length of the welding head 9.

[0033] In one embodiment of the present invention, a square opening is provided on the bottom plate 601, and the inner cavity of the square opening is movably sleeved on the outer side of the display rod 704, and the bottom of the display rod 704 is located below the bottom of the bottom plate 601. The bottom plate 601 is connected to the display rod 704 through the square opening, so that the display rod 704 can be extended from the bottom of the bottom plate 601.

[0034] In one embodiment of the present invention, the pressure plate seat 703 and the spring 702 are inclined and consistent with the inclination angle and direction of the welding head 9 , and the top of the pressure plate seat 703 is located above the bottom of the welding head 9 .

[0035] In one embodiment of the present invention, a cleaning brush 10 is fixedly mounted on the top of the platen seat 703, and the cleaning brush 10 is in a U-shape. The cleaning brush 10 is provided on the top of the platen seat 703, and when the welding head 9 enters the top of the bottom plate 601 and contacts the cleaning brush 10 on the platen seat 703, the cleaning brush 10 is used to clean the welding residues remaining on the welding head 9, so as to facilitate the next use of the welding head 9.

[0036] In one embodiment of the present invention, the front side of the pressing plate seat 703 is in an arc shape, and the pressing plate seat 703 is located directly behind the welding head 9. The front side of the pressing plate seat 703 is in an arc shape, so that the welding head 9 is easy to contact with the front side of the pressing plate seat 703, and the pressing plate seat 703 is pressed downward, so that the length of the welding head 9 is easy to observe.

[0037] In one embodiment of the present invention, the height of the second gear 605 is twice the height of the first gear 604, the rack 606 is meshed with the lower part of the first rotating shaft 602, the rack 606 is located below between the second gear 605 and the first gear 604, and does not contact the first gear 604, and the square socket 607 is located behind the rack 606. Due to the size relationship between the first gear 604 and the second gear 605, when the rack 606 is meshed with the second gear 605, the meshing between the second gear 605 and the first gear 604 is not affected, so that the rack 606 moves to drive the second gear 605 and the first gear 604 to rotate.

[0038] In one embodiment of the present invention, the protective cover 608 is in an arc shape as a whole, and an arc groove is provided on the protective top 609. The shape characteristics of the protective cover 608 facilitate protection of the welding rod 8 and the welding head 9, and the arc groove is provided on the protective top 609, which facilitates the support seat 5 to enter the position of the protective top 609.

[0039] Working principle: When using the device, when the welding rod 8 and the welding head 9 are not needed, the X-axis conveying mechanism 3 drives the support seat 5 to drive the rack 606 to move backward. Since the rack 606 is meshed with the second gear 605, and the second gear 605 is meshed and connected with the first gear 604, the first rotating shaft 602 and the second rotating shaft 603 are driven to rotate in opposite directions, so that the protective covers 608 on the second rotating shaft 603 and the first rotating shaft 602 rotate toward the direction of the rack 606 respectively. When the welding rod 8 and the welding head 9 move to the top of the bottom plate 601, the protective cover 608 is used to cover the welding rod 8 and the welding head 9;

[0040] At this time, the welding head 9 moves to a position in contact with the front side of the pressing plate seat 703. The pressing plate seat 703 is pressed by utilizing the shape characteristics of the pressing plate seat 703, and the telescopic rod 701 and the spring 702 are compressed, so that the display rod 704 and the scale 705 move downward. By observing the height of the display rod 704, the remaining length of the welding head 9 can be known. When the welding head 9 is shorter, it can be replaced in time.

[0041] When the welding head 9 continues to move backward, it contacts the cleaning brush 10, and the cleaning brush 10 is used to clean the welding residues remaining on the welding head 9;

[0042] When the welding rod 8 and the welding head 9 are needed, the X-axis conveying mechanism 3 is used to drive the movable seat 4 to move forward. According to the same principle as above, the rack 606 is used to drive the protective cover 608 and the protective cover 608 on the second rotating shaft 603 and the first rotating shaft 602 to open outward, so that the welding rod 8 and the welding head 9 are moved away from the upper part of the base plate 601 without affecting the normal use of the welding rod 8 and the welding head 9.

[0043] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
