[0007] Optionally, it further includes a camera; a camera is installed on the mounting plate.

[0008] Optionally, electric guide rails are opened on all the mounting plates, and a number of electric drive moving blocks are provided in all the electric guide rails. Both ends of the mounting rod are respectively connected to the electric drive moving blocks in the corresponding electric guide rails.

[0009] Optionally, it further includes a cleaning plate; a cleaning plate for cleaning welding slag is fixedly connected to the mounting plate where the electric fixator I is installed.

[0010] Optionally, a guiding part is provided on the arc-shaped plate, and a cover plate is detachably connected to the left part of the guiding part.

[0011] Optionally, a plurality of suction ports are formed on the arc-shaped plate, and sponge blocks for preventing welding slag from entering are provided on all the suction ports.

[0014] Optionally, a blowing pipe is further included; a plurality of blowing pipes are fixedly connected to the arc-shaped plate.

[0015] The beneficial effects of the present invention are as follows: By adding an arc-shaped plate to the mounting rod, the welding area of the automobile tail pipe is shielded by the arc-shaped plate, and the welding slag splashing to the periphery is restricted within the arc-shaped plate, preventing the welding slag from splashing onto the operator and causing harm to the operator.

[0016] By adding a sealing plate and a filter screen to the arc-shaped plate, the arc-shaped plate, the sealing plate, and the filter screen together form a collection space. When the welding slag splashes onto the filter screen, the filter screen restricts and collects the larger welding slag, while the smaller welding slag and debris pass through the filter screen and are collected by the arc-shaped plate, facilitating the collection of the welding slag.

[0017] The present invention captures the diffused flue gas through the suction force of the suction ports, preventing the flue gas from diffusing to the periphery and affecting the surrounding environment.

During the rotation of the mounting rod, the fixed plate, the arc-shaped plate, the sealing plate, and the filter screen, a cleaning plate is added to the mounting plate on the right. The cleaning plate contacts the filter screen. When the electric guide rail drives the mounting rod to rotate, the cleaning plate cleans the surface of the filter screen, removing the welding slag adhered to the surface of the filter screen, which is beneficial to the cleaning of the welding slag. Affected by gravity, the welding slag on the collection space and the filter screen gradually transfers to the guiding part. After the mounting rod completes the rotation, all the cleaned welding slag accumulates in the guiding part. At this time, only need to remove the cover plate on the guiding part, and the welding slag accumulated in the guiding part can be taken out, facilitating the transfer of the welding slag.

[0019] The present invention knocks on the filter screen through a cleaning rod, causing the entire filter screen to vibrate, making it easier for the fine welding slag on the filter screen to fall off, which is conducive to the cleaning of the welding slag. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] The following describes the embodiments of the present invention with reference to the accompanying drawings. Embodiment 1

[0023] A welding device for environmentally friendly automotive parts, as Figures 1-6 shown, includes a workbench 1 and a welding robot 2; the workbench 1 is equipped with the welding robot 2; It further includes a mounting plate 3, mounting rods 4, a fixing plate 5 and an arc plate 6; two mounting plates 3 are mounted on the workbench 1; two mounting rods 4 are mounted on the left mounting plate 3, and an electric fixator I 31 is provided on the right mounting plate 3; all the mounting rods 4 are commonly slidably connected with a fixing plate 5, an electric fixator II 51 is provided on the fixing plate 5, and a linear driver is provided on the fixing plate 5 for driving the fixing plate 5 to move on the mounting rods 4; driving motors are provided on both the right mounting plate 3 and the fixing plate 5; the output shaft of the driving motor on the right mounting plate 3 passes through the mounting plate 3 and is connected to the electric fixator I 31, and the output shaft of the driving motor on the fixing plate 5 passes through the fixing plate 5 and is connected to the electric fixator II 51; an arc plate 6 is commonly mounted on the right sides of all the mounting rods 4, the arc plate 6 is located between the right mounting plate 3 and the fixing plate 5, and the arc plate 6 is connected to the right mounting plate 3.

[0024] It further includes a sealing plate 7 and a filter screen 8; a sealing plate 7 is fixedly connected to the arc plate 6; a filter screen 8 is fixedly connected to the sealing plate 7, and anti-sticking coatings are provided on both the filter screen 8 and the arc plate 6; the arc plate 6, the sealing plate 7 and the filter screen 8 commonly form a collection space.

[0025] It further includes a camera 101; a camera 101 is mounted on the right mounting plate 3.

[0026] Electric guide rails 32 are opened on all the mounting plates 3, and two electric drive moving blocks are provided in all the electric guide rails 32, and both ends of the mounting rod 4 are respectively connected to the electric drive moving blocks in the corresponding electric guide rails 32.

[0027] It further includes a cleaning plate 102; a cleaning plate 102 is fixedly connected to the right mounting plate 3.

[0028] A guiding part 61 is provided at the rear of the arc plate 6, and a cover plate is detachably connected to the left part of the guiding part 61, which is convenient for collecting welding slag.

[0029] A plurality of suction ports 62 are opened on the arc plate 6, and sponge blocks are provided on all the suction ports 62, which is better for collecting welding slag and fumes.

[0030] The suction ports 62 of the arc plate 6 are higher than the inner ring surface of the arc plate 6, so that the welding slag will not pass through the suction ports 62 when moving on the arc plate 6, preventing the pores of the sponge blocks from being blocked by the welding slag.

[0031] Before welding the automobile tail pipe, the operator fixes the parts to be welded on the electric fixator I 31 and the electric fixator II 51 respectively. Then, the linear driver on the fixing plate 5 is started, and the fixing plate 5 drives the part fixed on the electric fixator II 51 to move towards the electric fixator I 31. After the parts on the electric fixator II 51 and the electric fixator I 31 are combined to form the prototype of the automobile tail pipe, the movement of the fixing plate 5 is stopped. Then, the workbench 1 is controlled to drive the welding robot 2 to move to the area where the automobile tail pipe needs to be welded. The driving motors on the welding robot 2, the electric fixator I 31 and the electric fixator II 51 are started, and the driving motors drive the automobile tail pipe fixed on the electric fixator I 31 and the electric fixator II 51 to rotate, so as to cooperate with the welding robot 2 to carry out the welding operation on the automobile tail pipe.

[0032] During the welding of the automobile tail pipe, the welding slag generated by welding will splash to the surrounding area, and the welding slag will splash onto the operator. Moreover, the temperature of the newly generated welding slag is relatively high. After the welding slag comes into contact with the operator's skin, the high-temperature welding slag will scald the operator's skin. By adding an arc-shaped plate 6 to the mounting rod 4, the arc-shaped plate 6 shields the welding area of the automobile tail pipe, restricts the welding slag splashing to the surrounding area within the arc-shaped plate 6, and prevents the welding slag from splashing onto the operator and causing harm to the operator.

[0033] By adding a sealing plate 7 and a filter screen 8 to the arc-shaped plate 6, the arc-shaped plate 6, the sealing plate 7 and the filter screen 8 jointly form a collection space. When the welding slag splashes onto the filter screen 8, the filter screen 8 restricts and collects the larger welding slag, while the smaller welding slag and debris pass through the filter screen 8 and are collected by the arc-shaped plate 6, which is convenient for the collection of welding slag.

[0034] During the welding of the automobile tail pipe, the welding fumes generated by welding diffuse to the surrounding area, affecting the surrounding environment. By adding a suction port 62 to the arc-shaped plate 6, before welding the automobile tail pipe, the arc-shaped plate 6 is connected to an external vacuum generator. When the welding fumes generated during the welding of the automobile tail pipe diffuse to the surrounding area, the external vacuum generator is started to provide suction force for the suction port 62, and the diffused welding fumes are captured by the suction force of the suction port 62, preventing the welding fumes from diffusing to the surrounding area and affecting the surrounding environment.

[0035] By adding a camera 101 to the mounting plate 3 on the right, the camera 101 is used to check the situation of the automobile tail pipe, providing the welding situation of the automobile tail pipe for the welding robot 2, so that the welding robot 2 can weld the automobile tail pipe better.

[0036] By opening an electric guide rail 32 on the mounting plate 3, the mounting rods 4 are made to slide within the electric guide rail 32. After the welding of the automobile tail pipe is completed and the operator removes the welded automobile tail pipe, it is necessary to clean the welding slag collected in the collection space. At this time, smaller welding slag and debris accumulate in the collection space, and larger welding slag accumulates on the filter screen 8. The electric guide rail 32 drives the mounting rod 4 to rotate counterclockwise by 180 degrees when viewed from left to right. The fixing plate 5, the arc plate 6, the sealing plate 7, and the filter screen 8 rotate accordingly. During the rotation of the mounting rod 4, the fixing plate 5, the arc plate 6, the sealing plate 7, and the filter screen 8, due to the influence of gravity, the smaller welding slag and debris collected by the arc plate 6 and the welding slag on the filter screen 8 fall to the ground, facilitating the cleaning of the welding slag in the collection space and on the filter screen 8.

[0037] It should be noted that when the larger welding slag directly falls on a flat surface, the welding slag still has a lot of heat, which will cause the welding slag to adhere to the flat surface. When the larger welding slag falls on the filter screen 8, due to the smaller contact area and the anti-adhesion coating provided on the filter screen 8, the adhesion force between the welding slag and the filter screen 8 is small. Additionally, by adding a cleaning plate 102 to the right mounting plate 3, the cleaning plate 102 contacts the filter screen 8. When the electric guide rail 32 drives the mounting rod 4 to rotate, the cleaning plate 102 cleans the surface of the filter screen 8, removing the welding slag adhered to the surface of the filter screen 8, which is conducive to the cleaning and collection of the welding slag.

[0038] By adding a guiding part 61 at the rear of the arc plate 6, during the process of the cleaning plate 102 cleaning the surface of the filter screen 8 and removing the welding slag on the surface of the filter screen 8, the cleaning plate 102 pushes the removed welding slag towards the rear of the arc plate 6. The removed welding slag gradually transfers into the guiding part 61. After the mounting rod 4 finishes rotating, all the removed welding slag accumulates in the guiding part 61. At this time, only need to remove the cover plate on the guiding part 61, and the welding slag accumulated in the guiding part 61 can be taken out, facilitating the transfer of the welding slag. Embodiment 2

[0039] On the basis of Embodiment 1, as Figure 3 、 Figure 4 and Figure 6 shown, it further includes a cleaning rod 103; several reinforcing ribs 81 are arranged on the filter screen 8 in a staggered manner; several cleaning rods 103 are slidably connected to the front side of the cleaning plate 102, and springs 1031 are provided at the connection positions of the cleaning plate 102 and all the cleaning rods 103.

[0040] It further includes a blowing pipe 110; two blowing pipes 110 are fixedly connected to the arc plate 6.

[0041] Taking into account that the cleaning plate 102 is unable to clean the fine welding slag on the filter screen 8 during the process of cleaning the welding slag on the filter screen 8, and the cleaning effect is poor, by adding a cleaning rod 103 in the cleaning plate 102, when the cleaning rod 103 contacts the reinforcing rib 81, the spring 1031 at the connection between the cleaning plate 102 and the cleaning rod 103 is in a state of force contraction. When the cleaning rod 103 is no longer in contact with the reinforcing rib 81, the spring 1031 at the connection between the cleaning plate 102 and the cleaning rod 103 is restored, and the spring 1031 pushes the cleaning rod 103 out of the cleaning plate 102. The pushed-out cleaning rod 103 knocks on the filter screen 8, causing the filter screen 8 to vibrate as a whole, thereby driving the arc plate 6 to vibrate, making it easier for the fine welding slag to fall off, which is beneficial to the cleaning of the welding slag.

[0042] By adding an air blowing pipe 110 to the curved plate 6, the air blowing pipe 110 is connected to an external air source before the welding operation of the automobile tail pipe is carried out. When the welding operation of the automobile tail pipe is started, the external air source is started to transport air into the air blowing pipe 110, and the air is ejected from the air blowing pipe 110. The ejected air forms an air curtain on the curved plate 6. The air curtain restricts the fume generated by welding, so that the fume generated by welding is better confined in the curved plate 6 and better captured by the suction port 62.

[0043] The technical principles of the embodiments of the present invention have been described above in conjunction with specific embodiments. These descriptions are intended solely to explain the principles of the embodiments of the present invention and should not be construed in any way as limiting the scope of protection of the embodiments of the present invention. Based on the explanations herein, those skilled in the art will be able to conceive of other specific implementations of the embodiments of the present invention without inventive effort, and such implementations will fall within the scope of protection of the embodiments of the present invention.
