[0002] In modern manufacturing, the efficient operation and welding quality of spot welding machines not only depend on the welding process itself, but are also closely related to the accuracy of raw material pretreatment.

[0003] Problems such as oxidation, oil stains, rust spots on the surface of metal materials need to be solved through the pretreatment mechanism of the spot welding machine.

[0004] The patent with publication number CN116252104A discloses a thin-walled steel pipe welding forming process, which includes: step 1, steel plate pretreatment, selecting thin-walled steel plates according to process requirements, grinding the welding edges on both sides of the steel plates to form a slope surface, and polishing the entire surface to remove surface rust and ash after grinding; step 2, bending and sizing process, sending the pretreated steel plates into a bending mechanism, bending the thin-walled steel plates into a tube through the continuous action of multiple groups of rollers, and aligning the welding edges on both sides in parallel; step 3, heating and welding process, preheating the steel pipe after bending and sizing, and then entering the high-frequency induction welding area for welding; pretreating the steel strip to significantly reduce the height of the weld bulge.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] (1) The raw material pretreatment mechanism of the efficient and intelligent spot welding machine initially locates the end position of the metal pipe fitting. After the metal pipe fitting is wrapped with the binding belt, the inner frame slides along the moving frame to the other side, and the metal pipe fittings on both sides can be docked. During the process of placing the metal pipe fitting, the welding position of the metal pipe fitting is located, thereby improving the positioning and fixing performance.

[0030] (2) The raw material pretreatment mechanism of the efficient intelligent spot welding machine tightens the strap to make it adhere to the outside of the metal pipe to bind it. Through the binding and fixing of the strap, this fixing method can make the strap automatically adapt to the shape of the pipe for fixing, thereby improving the diversity of the fixing form, adapting to a variety of pipes, and increasing the scope of application.

[0031] (3) The raw material pretreatment mechanism of the efficient and intelligent spot welding machine can automatically drive the metal pipe to move to the center position of the frame component during the process of the binding tape gradually wrapping the metal pipe, so as to align the metal pipe during the clamping process and improve the accuracy of the pretreatment docking.

[0032] (4) The raw material pretreatment mechanism of the efficient and intelligent spot welding machine can avoid the hard contact between the pipe and the mechanism caused by the vibration generated during the processing through the retention of the straps, thereby improving the service life.

[0033] (5) The raw material pretreatment mechanism of the efficient and intelligent spot welding machine can evenly distribute the clamping force on the pipe on the outside of the pipe, thus evenly clamping the pipe to avoid deformation of the pipe and improve the safety of the workpiece.

[0034] (6) The raw material pretreatment mechanism of the efficient intelligent spot welding machine starts the brush roller, the second laser processing head and the second ultrasonic processing head. The second laser processing head performs laser crushing on the impurities on the inner wall of the pipe fitting, and then the second ultrasonic processing head ultrasonically peels off the impurities. The second ultrasonic processing head swings along the swing rail to peel off the impurities toward the position of the brush roller, and then the brush roller cleans the fallen impurities, thereby improving the comprehensiveness of the treatment inside the pipe fitting.

[0035] (7) The raw material pretreatment mechanism of the efficient and intelligent spot welding machine drives the brush roller to rotate clockwise through the contact between the friction roller and the brush roller. At the same time, the tooth plate inserted into the brush roller peels off the remaining debris in the brush roller. The fallen debris slides into the collection frame through the arc surface of the cleaning seat and is collected. The magnetic debris is adsorbed by the adsorption plate and cleaned regularly, thereby improving the automatic cleaning capability.

[0036] (8) The raw material pretreatment mechanism of the efficient intelligent spot welding machine slides the moving rod along the electric sleeve so that the adjustment beams on both sides fit the pipe from the side, which plays an auxiliary stabilizing role and further improves the stability during processing.

[0037] (9) The raw material pretreatment mechanism of the efficient intelligent spot welding machine directly feeds the pipe fittings into the welding equipment through the frame components, and continues to connect the pipe fittings on both sides through the inner frame, and then welds them through the welding equipment. By performing internal and external treatments on the welding ends of the pipe fittings before welding, the welding quality of the pipe fittings is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0077] The working principle of the present invention is as follows:

[0078] Initially, the two belt rollers 308 of the lower inner frame 305 are set far apart, and the two belt rollers 308 of the upper inner frame 305 are set close to each other. The band 313 is triangular in shape under the control of the band roller 308 and the band frame 312. The electric control shift rod 404 slides along the electric sleeve 403 to bring the two adjustment beams 405 closer together, and the metal pipe fittings are inserted into the band 313 and placed with the end faces against the frame plate component 4, i.e., the end positions of the metal pipe fittings are initially positioned. After the band 313 wraps the metal pipe fittings, the inner frame 305 slides to the other side along the shift frame 301, so that the metal pipe fittings on both sides can be docked. In the process of placing the metal pipe fittings, the welding positions of the metal pipe fittings are located, thereby improving the positioning and point fixing performance.

[0079] After the metal pipe is inserted into the band 313, the cylinder 310 is started to move the band frame 312 downward to fit the metal pipe, and the two band rollers 308 of the lower inner frame 305 are set close to each other, and the two band rollers 308 of the upper inner frame 305 are set far apart, thereby tightening the band 313 to make it adhere to the outside of the metal pipe to bind it. Through the binding and fixing of the band 313, this fixing method can make the band 313 automatically adapt to the shape of the pipe for fixing, thereby improving the diversity of fixing forms, adapting to a variety of pipes, and improving the scope of application.

[0080] The two belt rollers 308 slidingly connected on the inner frame 305 slide synchronously along the rail 307 through the slider 309. Through the symmetrical adjustment of the belt rollers 308, the metal pipe can be automatically moved to the center position of the frame component 3 during the process of the binding belt 313 gradually wrapping the metal pipe, so that the metal pipe can be positioned correctly during the process of clamping it, thereby improving the accuracy of pre-treatment docking.

[0081] After the frame component 3 fixes the metal pipe fittings, the metal pipe fittings will be pre-processed by the internal processing component and the external processing component respectively. The fixation of the binding belt 313 can avoid the hard contact between the pipe fittings and the mechanism caused by the vibration generated during the processing, thereby improving the service life.

[0082] The pipe is flexibly clamped by the binding band 313, and the pipe is wrapped and fixed by the binding band 313, so that the clamping force on the pipe is evenly distributed on the entire outside of the pipe, the pipe is clamped evenly, deformation of the pipe is avoided, and the safety of the workpiece is improved.

[0083] After the pipe is positioned and fixed in place, the two adjustment beams 405 are moved away from each other to expose the end of the pipe, and the processing head assembly is inserted into the pipe by adjusting the mechanical hinge arm 203, and the brush roller 205, the second laser processing head 208 and the second ultrasonic processing head 209 are started synchronously. The second laser processing head 208 laser-crushes the impurities on the inner wall of the pipe, and then the second ultrasonic processing head 209 ultrasonically peels off the impurities, and the second ultrasonic processing head 209 swings along the swing rail 207 to peel off the impurities toward the position of the brush roller 205, and then the brush roller 205 cleans the fallen impurities to improve the comprehensiveness of the processing inside the pipe.

[0084] The processing head assembly is retracted into the processing seat 201 in situ through the adjustment of the mechanical hinge arm 203. At this time, the processing head assembly is inserted into the cleaning assembly, and the motor 213 is started to drive the friction roller 214 to rotate. The contact between the friction roller 214 and the brush roller 205 drives the brush roller 205 to rotate clockwise. At the same time, the tooth plate 212 inserted into the brush roller 205 is used to peel off the remaining debris in the brush roller 205. The detached debris slides into the collection frame 216 through the curved surface of the cleaning seat 211 for collection. The magnetic debris is adsorbed by the adsorption plate 215 and cleaned regularly, thereby improving the automatic cleaning capability.

[0085] After the internal processing of the pipe is completed, the rail block 103 is slid along the shift rail 102 to slide the frame component 3, the frame plate component 4 and the pipe to be processed to the location of the external processing frame 104, and the inner frame 305 is slid along the shift frame 301 so that the pipes on both sides are abutted in the external processing frame 104. At this time, the shift rod 404 is slid along the electric sleeve 403 so that the adjustment beams 405 on both sides are abutted against the pipe from the side, which plays an auxiliary stabilizing role and further improves the stability during processing.

[0086] The first laser processing head 107 and the first ultrasonic processing head 108 slidingly arranged in the outer processing frame 104 pre-process the outer surface of the pipe in a circular motion. After the processing is completed, the pipes on both sides are separated again, and the shift rail 102 is docked with the track of the welding equipment, so that the frame component 3 directly sends the pipe into the welding equipment, and continues to dock the pipes on both sides through the inner frame 305, and then welded by the welding equipment. By performing internal and external processing on the welding ends of the pipe before welding, the welding quality of the pipe is assisted to be improved.

[0087] 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.
