In order to prevent problems during welding from affecting the quality and efficiency of welding, a welding mistake proofing device is often used during welding.

[0040] As a further improvement of the invention, as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the cleaning smearing mechanism 1 comprises a connecting frame 101 fixedly connected with the moving rod 206, the inner wall of the connecting frame 101 is fixedly connected with brush hairs 102, the material of the brush hairs 102 is high-temperature-resistant steel wire brush, the bottom end inner side of the connecting frame 101 is fixedly connected with a guide shaft 103, the vertical center line of the guide shaft 103 is slidably connected with a liquid passing shell 106 at both ends, the inner side of the liquid passing shell 106 is fixedly connected with a smearing plate 105, the smearing plate 105 is made of ceramic fiber sponge, so that the protective liquid flowing out of the liquid passing shell 106 can enter the inner side of the smearing plate 105, and then can be smeared on the surface of the nozzle 5 through the smearing plate 105, the vertical center line of the guide shaft 103 is provided with a first spring 104 at both ends, and the two ends of the first spring 104 are fixedly connected with the liquid passing shell 106 and the connecting frame 101 respectively, one end of the liquid passing shell 106 is communicated with a liquid delivery assembly, the first spring 104 provides a pulling force to the liquid passing shell 106, when the brush hairs 102 normally clean the splashes on the surface of the nozzle 5, the first spring 104 moves the liquid passing shell 106 and the smearing plate 105 away from the vertical center line of the connecting frame 101 under the condition that the liquid passing shell 106 is not subjected to other external forces, so that the end of the brush hairs 102 leaks out, when the connecting frame 101 is sleeved on the inner side of the nozzle 5 on both sides, the brush hairs 102 on the inner wall of the connecting frame 101 can be in contact with the inner wall and the outer surface of the nozzle 5, so that the brush hairs 102 can clean the splashes on the inner wall and the outer surface of the nozzle 5 at the same time, ensure that the splashes are cleaned in time, avoid the decrease of the heat dissipation efficiency of the nozzle 5 or the deterioration of the gas protection effect caused by the accumulation of residual materials, and effectively prevent the quality problems such as welding seam porosity and incomplete fusion caused by splashes by actively intervening in the potential defect causes in the welding process, realize closed-loop error-proof control from monitoring to processing;

[0041] At the same time, under the action of the motor 9, the second gear 10, the gear ring 11, the guide frame 13, the adjusting mechanism 2 and the connecting frame 101, the brush hairs 102 can rotate around the nozzle 5, so as to clean the splashes attached to the nozzle 5.

[0042] As a further improvement of the application, as Figure 4 、 Figure 5 and Figure 6As shown, the infusion assembly comprises a telescopic pipe 108 in communication with the liquid passage shell 106, which can be a high-temperature-resistant metal corrugated telescopic pipe to ensure normal movement of the liquid passage shell 106, and the outlet end of the telescopic pipe 108 is in communication with a first one-way valve 109, and the first liquid guide pipe 107 is in communication between adjacent telescopic pipes 108, which is a high-temperature-resistant hose, such as a high-temperature-resistant metal hose, to ensure normal movement of the liquid passage shell 106, and the inlet end of the first liquid guide pipe 107 is in communication with a connecting block 110, which is made of iron, and the inner side of the connecting block 110 is provided with a liquid guide block 111, the outer side of the liquid guide block 111 is fixedly connected with a sealing ring 117, and the liquid guide block 111 is slidably connected with the connecting block 110 through the sealing ring 117, and the inner side of the liquid guide block 111 is provided with a first liquid guide hole 114 and a second liquid guide hole 115 in communication with each other, and the inner side of the connecting block 110 is provided with a transition hole 116, the diameter of the transition hole 116 is larger than that of the second liquid guide hole 115, so that the protective liquid flowing out of the second liquid guide hole 115 can flow to the inner side of the connecting block 110 through the transition hole 116.When the protective liquid needs to be introduced into the inside of the liquid passage shell 106 and the inside of the smearing plate 105, the liquid guide rod 306 in the inside of the pressing mechanism 3 is inserted into the first liquid guide hole 114, and the liquid guide block 111 is pressed downward by the liquid guide rod 306, so that the second liquid guide hole 115 in the inside of the liquid guide block 111 is aligned with the transition hole 116, and the protective liquid flowing out of the second liquid guide hole 115 flows into the inside of the connecting block 110 through the transition hole 116, and then flows into the inside of the telescopic tube 108 through the first liquid guide tube 107. Due to the action of the first one-way valve 109, the protective liquid first fills the telescopic tube 108, so that the telescopic tube 108 is first elongated, and the telescopic tube 108 will slide along the guide shaft 103 with the liquid passage shell 106 and the smearing plate 105 overcoming the pulling force of the first spring 104 until the smearing plate 105 is attached to the nozzle 5. At this time, the liquid passage shell 106 and the smearing plate 105 stop moving. Due to the continuous introduction of the protective liquid into the inside of the telescopic tube 108, the pressure in the inside of the telescopic tube 108 increases, and the first one-way valve 109 is opened at this time, so that the protective liquid enters the inside of the smearing plate 105 through the liquid passage shell 106. The first one-way valve 109 is a trace one-way valve, and after the first one-way valve 109 is opened, the liquid flowing out through the first one-way valve 109 is much smaller than the liquid introduced into the inside of the telescopic tube 108 through the first liquid guide tube 107, so that the pressure in the inside of the telescopic tube 108 can always be attached to the nozzle 5 with the smearing plate 105 through the liquid passage shell 106. After the protective liquid enters the inside of the smearing plate 105, the first liquid guide tube 107 stops introducing liquid into the inside of the telescopic tube 108, and then the liquid guide block 111 is quickly separated from the transition hole 116 under the elastic force of the second spring 113, and the first one-way valve 109 is also reset, so that the pressure in the inside of the first liquid guide tube 107 and the telescopic tube 108 is unchanged, and the smearing plate 105 is attached to the nozzle 5. When the smearing plate 105 rotates along the nozzle 5, the protective liquid can be uniformly smeared on the inner wall and the outer surface of the nozzle 5.

[0043] After smearing is completed, the liquid guide rod 306 is re-inserted into the first liquid guide hole 114, and at this time the liquid guide rod 306 does not introduce the protective liquid into the inside of the first liquid guide hole 114. At this time, the first spring 104 moves the liquid passage shell 106 and the smearing plate 105 away from the vertical center line of the connecting frame 101, and the telescopic tube 108 is also reset. The excess gas in the inside of the first liquid guide tube 107 and the telescopic tube 108 flows back to the inside of the liquid guide rod 306. After the smearing plate 105 is separated from the nozzle 5, the connecting frame 101 can be moved from the lower side of the nozzle 5 to the side of the nozzle 5.

[0044] As a further improvement of the present application, as Figure 6As shown in the figure, the inner side of the liquid guide block 111 is slidingly connected with a guide rod 112, the outer side of the guide rod 112 is provided with a second spring 113, and the two ends of the second spring 113 are fixedly connected with the liquid guide block 111 and the connecting block 110 respectively, the second spring 113 provides an upward thrust force to the liquid guide block 111, and the thrust force can overcome the friction between the sealing ring 117 and the connecting block 110 to move the liquid guide block 111 upward, and the top end of the guide rod 112 is provided with a limiting protrusion to prevent the liquid guide block 111 from separating from the guide rod 112.

[0045] As a further improvement of the present application, as shown in the figure, Figure 7 、 Figure 8 、 Figure 9 and Figure 10 As shown in the figure, the adjusting mechanism 2 comprises a fixed frame 201 fixedly connected with the welding gun head 4, the inner side of the fixed frame 201 is provided with a first rotating shaft 203, the outer side of the first rotating shaft 203 is fixedly connected with a limiting sleeve 204, the first rotating shaft 203 is rotatably connected with the fixed frame 201 through the limiting sleeve 204, the material of the limiting sleeve 204 is anti-skid wear-resistant rubber, and through the friction between the limiting sleeve 204 and the fixed frame 201, when the cleaning and coating mechanism 1 is rotated to one side of the nozzle 5, the cleaning and coating mechanism 1 remains in position, ensuring that the normal welding work of the nozzle 5 is not affected; one end of the first rotating shaft 203 is fixedly connected with a first gear 202, the bottom end of the first gear 202 is fixedly connected with a fixed frame 205, the inner side of the fixed frame 205 is slidingly connected with a moving rod 206, one end of the moving rod 206 is provided with a clamping groove 208, one end of the moving rod 206 is provided with a pushing assembly, one end of the fixed frame 201 is fixedly connected with a limiting cylinder 213, the first liquid guide pipe 107 can pass through the inner side of the limiting cylinder 213, and the limiting cylinder 213 is used for limiting the first liquid guide pipe 107, ensuring the normal work of the first liquid guide pipe 107;
