[0039] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Fig.14 - Fig.15 As shown, a surface welding device for hardware processing includes: a welding mechanism, a displacement mechanism, a transmission mechanism, a clamping mechanism, a liquid spraying mechanism, a dust cleaning mechanism, a workbench 1, an upper frame 2, a first hardware 4 and a second hardware 10. A bottom through frame 21 is provided in the middle of the bottom end of the workbench 1, an upper frame 2 is provided at the top of the workbench 1, an electric control box board 3 is provided at the top of the upper frame 2, the second hardware 10 is provided on one side of the top of the workbench 1, and the first hardware 4 is provided on the other side of the top of the workbench 1;

[0041] The welding mechanism is used to perform welding processing on the connection between the first hardware part 4 and the second hardware part 10;

[0042] The displacement mechanism is used to move the positions of the first hardware component 4 and the second hardware component 10;

[0043] The transmission mechanism is used to provide power for the clamping mechanism, the liquid spraying mechanism and the dust cleaning mechanism;

[0044] The clamping mechanism is used to provide a resisting force to one side of the first hardware 4;

[0045] The liquid spraying mechanism is used for spraying the flux liquid;

[0046] The dust cleaning mechanism is used to remove dust on the surface of the first hardware component 4 and the second hardware component 10 .

[0047] The liquid spraying mechanism includes a spring 43, a movable block 42, a mounting rod 41, a liquid tank 40, an upper conduit 39, a push piece 38, a water spraying pipe 37, a rotating rod 36, a push rod 30, a vertical rod 29, a front frame 28 and a piston cylinder 22. The mounting rod 41 is arranged in the middle of the top of the upper frame 2, and the liquid tank 40 is arranged at one end of the mounting rod 41. The bottom end of the liquid tank 40 is arranged with the upper conduit 39, the bottom end of the upper conduit 39 is arranged with the piston cylinder 22, and the bottom end of the piston cylinder 22 is arranged with the water spraying pipe 37. The inside of the piston cylinder 22 A push piece 38 is provided on one side of the push piece 38, a push rod 30 is provided on one side of the push piece 38, a vertical rod 29 is provided on the bottom end of the push rod 30, a movable block 42 is provided on the bottom end of the vertical rod 29, a horizontal tube 44 is provided transversely through the middle of the movable block 42, a spring 43 is provided on one side of the outside of the horizontal tube 44, a front frame 28 is sleeved on the outside of the horizontal tube 44, a half gear 8 is provided on the bottom end of the movable block 42, an attached rotating rod 36 is provided on the back side of the half gear 8, and the attached rotating rod 36 and the half gear 8 are fixedly connected.

[0048] In addition, since the second motor assembly 16 can drive the main transmission gear 9 to rotate after being started, the auxiliary rotating rod 36 arranged at the front end of the main transmission gear 9 also rotates, and the half gear 8 arranged at the front end of the auxiliary rotating rod 36 also rotates synchronously, because the half gear 8 itself is a half wheel-shaped structure, and a sawtooth structure is arranged at the arc of the half gear 8, and the movable block 42 is placed at the upper end of the half gear 8, when the half gear 8 rotates, the sawtooth structure outside the half gear 8 will continuously drive the movable block 42 to move horizontally, and the movable block 42 simultaneously moves forward and backward outside the transverse tube 44 arranged horizontally inside the front frame 28, and the spring 43 helps the movable block 42 to reset after moving;

[0049] When the movable block 42 moves, the vertical rod 29 at the top of the movable block 42 drives the push rod 30 to reciprocate inside the piston cylinder 22. Due to the push piece 38 set at the front end of the push rod 30, the push piece 38 also performs synchronous reciprocating motion inside the piston cylinder 22 at this time. When the push piece 38 performs reciprocating motion, the flux liquid inside the liquid tank 40 is continuously introduced into the upper conduit 39 inside the piston cylinder 22. The upper conduit 39 introduces the flux liquid into the water spray pipe 37 when it moves to the rear side through the push piece 38. When the push piece 38 is pushed forward again, the liquid stored in the water spray pipe 37 will be pushed out by the gas generated by the push piece 38. The lead-out surface at the bottom of the water spray pipe 37 is placed at the upper end of the connection between the first hardware 4 and the second hardware 10, so the flux liquid sprayed from the water spray pipe 37 will be sprayed on the surface of the connection between the first hardware 4 and the second hardware 10, thereby providing a welding effect.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 - Fig. 9 As shown, a surface welding device for hardware processing, the clamping mechanism includes a pull plate 18, an upper rack 23, a slot 26 and an upper clamping column 27, upper clamping columns 27 are arranged on both sides of the bottom of the electric control box plate 3, and extensions are arranged on both sides of the bottom of the upper clamping column 27, and the outer side of the extension is provided with a slot 26, and the outer side of the slot 26 is provided with an upper rack 23, and the inner side of the slot 26 is clamped with a pull plate 18, the upper end of the pull plate 18 is a horizontal flat part, and the lower end of the pull plate 18 is a vertical wide part:

[0051] In addition, since the second motor assembly 16 drives the main transmission gear 9 to rotate, an upper rack 23 is placed on the top of the main transmission gear 9, and the sawtooth structure on the surface of the main transmission gear 9 meshes with the sawtooth structure at the bottom of the upper rack 23. A slot 26 is provided on the surface of the upper rack 23, and the pull plate 18 is composed of an upper transverse flat portion and a lower vertical wide portion. The transverse flat portion at the upper end of the pull plate 18 is inserted into the slot 26, and the lower vertical wide portion of the pull plate 18 is placed on the side of the first hardware 4. Therefore, when the main transmission gear 9 rotates, the upper rack 23 is horizontally moved by the rotational thrust of the main transmission gear 9, and the slot 26 on the surface of the upper rack 23 drives the pull plate 18 to move horizontally, and the vertical wide portion at the lower end of the pull plate 18 gradually approaches one side of the first hardware 4. When the vertical wide portion at the lower end of the pull plate 18 presses against one side of the first hardware 4, the first hardware 4 is moved by force;

[0052] The first hardware 4 is placed on the top of the positioning flap 17, and the two sides of the positioning flap 17 are provided with slide posts 35, which are inserted into the inner side of the side slide groove 34. Therefore, when the first hardware 4 moves, the positioning flap 17 at the bottom of the first hardware 4 will also move with the first hardware 4, and the side slide groove 34 and the slide posts 35 help the positioning flap 17 to move.

[0053] Because the first motor assembly 12 drives the ball screw 11 to rotate after starting, and the bearing block 20 sleeved on the outer side of the ball screw 11 moves horizontally, and the top of the bearing block 20 is connected to the moving plate 13, so the bearing block 20 drives the moving plate 13 to move horizontally, and because the second hardware 10 is placed on the top of the moving plate 13, the moving plate 13 drives the second hardware 10 to move horizontally;

[0054] In addition, when the second hardware 10 and the first hardware 4 gradually approach each other, the user directly starts the second motor assembly 16, the second motor assembly 16 drives the main transmission gear 9 to rotate, and the main transmission gear 9 drives the upper rack 23 to move horizontally, and the convex portion at the bottom end of the upper clamping column 27 is clamped in the inner side of the clamping groove 26 of the upper rack 23, so the upper rack 23 will move horizontally at a certain height position. After the upper rack 23 moves, the clamping groove 26 opened on the outside of the upper rack 23 clamps the upper horizontal flat portion of the pull plate 18. Therefore, when the upper rack 23 moves, the upper rack 23 will drive the pull plate 18 to gradually push the first hardware 4 close to one side of the second hardware 10, so that the welding connection between the first hardware 4 and the second hardware 10 is tightly pressed to prevent the first hardware 4 and the second hardware 10 from being misaligned when welding.

[0055] like Figure 1 - Fig.15 As shown, a surface welding device for hardware processing, the dust cleaning mechanism includes a cleaning structure 24 and an attached gear 25, the cleaning structure 24 is composed of a curved plate 241, a dust-absorbing roller 242, a convex column 243, a cylinder column 244 and a fixing plate 245, the attached gear 25 is arranged on one side of the main transmission gear 9, the convex column 243 is arranged in the middle of the front of the attached gear 25, the front end of the convex column 243 is arranged with a curved plate 241, the front side of the curved plate 241 is arranged with a dust-absorbing roller 242, the back side of the attached gear 25 is arranged with a cylinder column 244, one end of the cylinder column 244 is arranged with a fixing plate 245, the bottom of the fixing plate 245 is fixedly connected to the second slider 15;

[0056] In addition, since the second motor assembly 16 drives the main transmission gear 9 to rotate after starting, and the attached gear 25 is placed on one side of the main transmission gear 9, when the main transmission gear 9 rotates in one direction, the attached gear 25 rotates in the opposite direction. A protrusion 243 is fixedly provided at the front end of the attached gear 25. The front end of the protrusion 243 is engaged with the curved plate 241. A dust-absorbing roller 242 is fixedly provided at the front end of the curved plate 241. When the ball screw 11 is reversed, the first motor assembly 12 and the moving plate 13 reversely bring the finished welding product of the second hardware 10 and the first hardware 4 back. At this time, the second five The moving direction of the metal part 10 and the first hardware part 4 is toward the side of the first motor assembly 12, and then the attached gear 25 starts to rotate, and the attached gear 25 drives the protruding column 243 and the curved plate 241 to rotate, and at the same time the curved plate 241 drives the dust collecting roller 242 to rotate in a circle, and the surface of the dust collecting roller 242 continuously contacts the surface of the connection between the first hardware part 4 and the second hardware part 10. At this time, when the dust collecting roller 242 continuously contacts the surface of the connection between the first hardware part 4 and the second hardware part 10, the surface of the dust collecting roller 242 continuously removes the dust at the connection between the first hardware part 4 and the second hardware part 10;

[0057] In addition, the front end of the cylinder 244 is sleeve-connected with the attached gear 25, and the attached gear 25 can rotate on the outer side of the front end of the cylinder 244, and the cylinder 244 remains stationary. The fixing plate 245 is fixedly connected to the cylinder 244. At the same time, the fixing plate 245 limits the cylinder 244 and the attached gear 25 at the same height as the center of the main transmission gear 9, so as to ensure that the rotation plane of the attached gear 25 will not drop or rise.

[0058] Working principle: When using the surface welding device for hardware processing, first put the second hardware 10 and the first hardware 4 into the top of the moving plate 13 and the positioning flap 17 respectively, then start the first motor assembly 12, the first motor assembly 12 drives the ball screw 11 to rotate in the middle of the inner side of the bottom through frame 21 opened at the inner bottom end of the workbench 1, when the ball screw 11 rotates, the bearing block 20 on the outer side of the ball screw 11 drives the moving plate 13 to move horizontally, the second hardware 10 at the top of the moving plate 13 gradually approaches the first hardware 4 at the top of the positioning flap 17, and then start the second motor assembly 16, the second motor assembly 16 drives the main transmission gear 9 to rotate, the upper rack 23 at the top of the main transmission gear 9 is meshed with the sawtooth structure at the top of the main transmission gear 9, this When the main transmission gear 9 rotates, the upper rack 23 moves horizontally on the top of the main transmission gear 9. Since a slot 26 is provided on the surface of the upper rack 23, the elongated portion of the upper end of the pull plate 18 is inserted into the slot 26, and the upper clamping column 27 prevents the upper rack 23 from falling when it moves. Therefore, when the second motor assembly 16 drives the main transmission gear 9 to rotate, the upper rack 23 on the top of the main transmission gear 9 moves horizontally, and the upper rack 23 drives the pull plate 18 to approach one side of the first hardware 4. When the vertical surface of the pull plate 18 abuts against one side of the first hardware 4, the pull plate 18 moves with the upper rack 23, and at the same time, the vertical surface of the pull plate 18 pushes the first hardware 4 to approach one side of the second hardware 10, so that the first hardware 4 and the second hardware 10 are tightly attached without revealing a gap.

[0059] Since the top of the upper frame 2 is fixedly connected to the mounting rod 41, and the liquid tank 40 connected to one end of the mounting rod 41 provides flux liquid for the upper guide tube 39, when the main transmission gear 9 rotates, the main transmission gear 9 drives the auxiliary rotating rod 36 to rotate, and the half gear 8 at the front end of the auxiliary rotating rod 36 rotates, and the sawtooth structure of the half gear 8 continuously drives the movable block 42 to move horizontally, and the movable block 42 moves horizontally on the outside of the cross tube 44 at the same time, and the spring 43 helps the movable block 42 to reset after the horizontal movement, and the movable block 42 drives the vertical rod 29 and the push rod 30 to move when moving, and the push rod 30 drives the push piece 38 to move forward and backward inside the piston cylinder 22. When the push piece 38 moves, it continuously inflates and exhausts air inside the upper conduit 39 and the water spray pipe 37. When the upper conduit 39 is inflated for the first time, the liquid inside the liquid tank 40 does not flow in, and the water spray pipe 37 discharges the gas in the pipe. When the upper conduit 39 is exhausted for the first time, the solder flux liquid inside the liquid tank 40 enters the upper conduit 39 and then flows into the water spray pipe 37. When the push piece 38 performs the second inflation movement, the solder flux liquid stored in the water spray pipe 37 is quickly discharged to the surface of the connection between the first hardware 4 and the second hardware 10.

[0060] When the main transmission gear 9 rotates, the main transmission gear 9 drives the attached gear 25 to rotate, the attached gear 25 drives the protruding column 243 to rotate, the protruding column 243 drives the curved plate 241 to rotate, the curved plate 241 drives the dust collecting roller 242 to continuously perform circular motion, and the surface of the dust collecting roller 242 continuously removes dust contaminated at the connection between the first hardware 4 and the second hardware 10, and at the same time, the retaining plate 245 and the cylinder 244 help the center of the attached gear 25 and the center of the main transmission gear 9 to be on the same straight line;

[0061] When it is necessary to weld the connection between the first hardware 4 and the second hardware 10, the electric telescopic rod body 5 is started, and the electric telescopic rod body 5 pushes the rotating plate 7 to move forward and backward. When the rotating plate 7 moves forward, the bottom of the rotating plate 7 drives the pull tab 31 to move, and the pull tab 31 drives the sleeve frame 32 to deflect, and the sleeve frame 32 cooperates with the rotating shaft 33 to rotate, so as to adjust the position of the head of the welding gun head body 6. When the head position of the welding gun head body 6 is adjusted, the connection between the first hardware 4 and the second hardware 10 can be welded.

Many modifications and variations will be apparent to those of ordinary skill in the art.
