The air extraction pump 31 is located between the welded assembly 2 and the support rod 13 on the side adjacent to the support rod 13. The air extraction pump 31 is fixed on the top surface of the support plate 11. The air extraction pump 31 is provided with an air extraction port, and the air extraction pump 31 performs air extraction through the air extraction port, The air extraction port faces the side close to the welding assembly 2 to facilitate the absorption of waste generated during welding.
The two adsorption networks 32 are also located on both sides of the welding assembly 2, and are symmetrically distributed with the welding assembly 2 as the symmetrical center. The two adsorption networks 32 are arranged facing each other, and each adsorption network 32 is located between the welding assembly 2 and an air extraction pump 31; The longitudinal section of the adsorption network 32 is rectangular, the size of the adsorption network 32 is larger than the size of the air extraction pump 31, and the length direction of the adsorption network 32 is parallel to the length direction of the support plate 11; Through the arrangement of the adsorption network 32, air can pass through the adsorption network 32, and waste debris cannot pass through the adsorption network 32, thereby preventing waste debris from entering the air extraction pump 31 from the air extraction port, causing damage to the air extraction pump 31.
The storage plate 4 is also provided with two, which are also located on both sides 503844 of the welding assembly 2 and are symmetrically distributed with the welding assembly 2 as the symmetrical center; Each storage plate 4 is horizontally arranged and located on the side of one of the adsorption nets 32 adjacent to the air extraction pump 31.

Both sides of the mounting block 51 are provided with positioning slots 56, the depth direction of the positioning slot 56 is horizontal and perpendicular to the length direction of the adsorption plate. The size of the positioning block 52 and the size of the positioning slot 56 match each other, and the positioning block 52 is slidably arranged in the positioning slot 56 along the depth direction of the positioning slot 56; The spring 53 is also arranged in the positioning slot 56, and its length direction is the same as the depth direction of the positioning slot 56. The spring 53 is located between the positioning block 52 and the slot bottom of the positioning slot 56, with one end fixedly connected to the positioning block 52 and the other end fixedly connected to the slot bottom of the positioning slot 56. When the spring 53 is in a balanced state, the end of the positioning block 52 that is close to the spring 53 is located in the positioning slot 56, and the end that is away from the spring 53 is located outside the positioning slot 56.
The bottom of the end surface of the positioning block 52 away from the spring 33503844 is provided with a tilting surface. When the spring 53 is in equilibrium, the end of the tilting surface close to the spring 53 is located inside the positioning groove 56, and the end of the tilting surface away from the spring 53 is located outside the positioning groove 56;
When installing the storage plate 4, place the mounting block 51 above the mounting slot 14, and when placing the mounting block 51 downward in the vertical direction into the mounting slot 14, the inclined surface can abut with the side wall of the mounting slot 14, thereby enabling the positioning block 52 to enter the positioning slot 56, and the spring 53 is in a compressed state.
The side walls on both sides of the installation slot 14 are provided with a clamp slot symmetrically distributed with the installation slot 14 as the center of symmetry. The depth direction of the clamp slot 15 is parallel to the depth direction of the positioning slot 56, and the size of the clamp slot 15 and the size of the positioning block 52 are mutually compatible. When the installation block 51 is installed in the installation slot 14, the end of the positioning block 52 that is away from the spring 53 can be clamped in the clamp slot 15 under the action of the spring 53; A slider 54 is arranged in the card slot 15 along its depth direction. When the positioning block 52 is also located in the card slot 15, the slider 54 moves to the side in the card slot 15 that is far away from the installation slot 14 under the action of the positioning block 52.

The top end of the slide bar 55 is fixedly connected to the bottom surface of the slide 54, and the bottom end of the slide bar 55 is always located below the slide slot 16, Enabling the staff to operate the slide bar 55 under the support plate 11; And the width dimension of the slide slot 16 is smaller than the width dimension of the card slot 15, which can prevent the slide bar 55 from falling off from the slide slot 16; When the slide bar 55 is moved to the side near the installation slot 14 in the slide slot 16, the side near the installation slot 14 of the slide bar 54 is located at the junction of the installation slot 14 and the clamping slot 15. When the positioning block 52 is clamped in the clamping slot 15, the slide bar can be moved towards the direction near the installation slot 14 to drive the slide bar
54 to push the positioning block 52 into the positioning slot 56, and the installation block 503844 51 can be taken out of the installation slot 14.
Working principle: Before welding, first install the storage plate 4 onto the support plate 11, place the mounting block 51 above the mounting slot 14 and align it vertically with the mounting slot 14. Move the mounting block 51 downward until the mounting block 51 enters the mounting slot 14, and the inclined surface on the positioning block 52 abuts the side wall of the mounting slot 14. The positioning block 52 enters the positioning slot 56 to drive the spring 53 in a compressed state until the mounting block 51 is completely installed in the mounting slot 14, The positioning block 52 is aligned with the slot 15, and is clamped into the slot 15 under the action of the spring 53 to complete the installation of the storage plate 4. At this time, the workpiece to be welded can be placed under the welding head 23. The height of the welding head 23 can be adjusted through the electric telescopic rod 22 to facilitate welding of the workpiece. Then, the air extraction pump 31 and the welding head 23 are started to work, and the waste generated during welding can be adsorbed onto the adsorption network 32 under the action of the air extraction pump 31.
When the operation is stopped, the waste debris on the adsorption screen 32 can fall into the storage tank 41. At this time, move the slider 55 under the support plate 11 towards the direction close to the installation tank 14, drive the positioning block 52 to disengage from the card slot 15, and then pull out the storage plate 4 upward to facilitate cleaning of the waste debris in the storage tank 41.
The above is only a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any skilled person familiar with the technical field who, within the technical scope disclosed in this application, makes equivalent replacements or changes based on the technical solution of this application and its application concept should be covered by the scope of protection of this application.
