[0029] The feeding mechanism comprises a feeding channel 1, the bottom of the feeding channel 1 is communicated with a discharge frame 27, the inner wall of the discharge frame 27 is fixedly connected with two rubber strips 28, the two rubber strips 28 are made of rubber material, the upper surface of the feeding channel 1 corresponding to the discharge frame 27 is slidingly installed with a stop plate 4 through a through slot, the upper surface of the feeding channel 1 is fixedly connected with two first electric telescopic rods 3 for driving the stop plate 4 to move up and down through a fixed frame 2, and the side wall of the base 23 corresponding to one end of the arc plate 10 is fixedly connected with a press switch 29 for controlling the operation of the first electric telescopic rod 3.

[0030] When the mounting plate 21 is deflected and swings to below the discharge frame 27, the press switch 29 is extruded, a signal is transmitted to the single-chip microcomputer, the single-chip microcomputer controls the first electric telescopic rod 3 to work, so as to drive the stop plate 4 to move downward and act on the upper surface of the metal pipe, at this time, the single metal pipe overcomes the resistance of the rubber strip 28 and makes the rubber strip 28 deform, so as to fall to the upper surface of the arc plate 10 through the discharge frame 27, when the press switch 29 loses the extrusion effect, the first electric telescopic rod 3 starts to drive the stop plate 4 to reset upward, at this time, the next metal pipe enters the inside of the discharge frame 27, and the cycle is repeated, so as to complete the single automatic feeding process and improve the work efficiency.

[0031] Further, the swing mechanism comprises two mounting plates 21, the two mounting plates 21 are rotatably installed on the side wall of the base 23 through mounting seats 35, the two mounting plates 21 are fixedly connected with the arc plate 10, the inside of each of the two mounting plates 21 is provided with a sliding groove 31, the sliding groove 31 is slidingly installed with a sliding block 32, the opposite surfaces of the two sliding blocks 32 are rotatably installed with a hinge rod 30, the side wall of the base 23 where the mounting plate 21 is located is fixedly connected with a fixed plate 22, and the fixed plate 22 is fixedly installed with a motor 24 for rotating the hinge rod 30.

[0032] When the motor 24 is turned on, the hinged rod 30 is further driven to rotate. Due to the limiting sliding action of the sliding groove 31 and the sliding block 32, the mounting plate 21 is further deflected as a whole when the hinged rod 30 rotates counterclockwise and drives the sliding block 32 to slide in the sliding groove 31.

[0033] Further, the top of each of the two fixed plates 22 is connected with a cleaning mechanism for removing dirt from the front surface of the robot metal pipe before spraying. Each cleaning mechanism includes a fixed part 26 fixedly connected to the top of the fixed plate 22, a first gear 8 rotatably mounted on the upper surface of the fixed part 26 through a mounting block, a first rack 11 fixedly connected to the two sides of an arc-shaped plate 10 and engaged with the first gear 8, cleaning cotton fixedly connected to the upper surface of the arc-shaped plate 10, a spline groove 6 formed in the middle of the first gear 8, a spline shaft 38 slidably mounted in the inner wall of the spline groove 6, a control mechanism for fixing the metal pipe provided at one end of the spline shaft 38 close to the arc-shaped plate 10, and a baffle mechanism for stopping the metal pipe provided on the upper surface of the fixed part 26.

[0034] Through the structure and the action of the baffle mechanism, the two damping plates 7 clamp and fix the two ends of the metal pipe. When the mounting plate 21 is deflected downward and the rotating shaft 19 enters the electrolytic tank 16, the first gear 8 rotates when the mounting plate 21 drives the first rack 11 to move in an arc shape due to the meshing action of the first gear 8 and the first rack 11. When the first gear 8 drives the metal pipe to rotate as a whole, the cleaning cotton provided on the upper surface of the arc-shaped plate 10 can clean the outer wall of the metal pipe through relative movement between the two, thereby further improving the spraying quality.

[0035] Further, the baffle mechanism includes a mounting part 40 fixedly connected to the upper surface of the fixed part 26, an active strip 39 slidably mounted in a through hole of the mounting part 40, a baffle plate 9 connected to one end of the active strip 39, a second electric telescopic rod 41 fixedly connected to the mounting part 40 for movement of the active strip 39, and a piston mechanism connected to the side wall of the fixed part 26.

[0036] Due to the blocking action of the baffle plate 9, the metal pipe can be stopped on the upper surface of the arc-shaped plate 10. At this time, the single-chip microcomputer controls the second electric telescopic rod 41 to work, and the second electric telescopic rod 41 drives the baffle plate 9 to separate to both sides, which makes the baffle plate 9 gradually separate from the wall of the metal pipe.

[0037] Further, the piston mechanism comprises a first piston sleeve 36 and a second piston sleeve 37, the first piston sleeve 36 and the second piston sleeve 37 are fixedly installed on the side wall of the fixed part 26, the second piston plate 43 is slidably installed in the first piston sleeve 36, the first piston plate 42 is slidably installed in the second piston sleeve 37, the first piston plate 42 is rotatably connected to the end of the spline shaft 38 away from the spline groove 6, and the other end of the movable strip 39 extends into the first piston sleeve 36 and is fixed to the side wall of the second piston plate 43.

[0038] When the shielding plate 9 gradually separates from the metal pipe wall, the second piston plate 43 is driven to move in the first piston sleeve 36, and the air in the first piston sleeve 36 is compressed to enter the second piston sleeve 37, and the second piston sleeve 37 further drives the spline shaft 38 to move towards one end of the spline groove 6, so that the two damping plates 7 clamp and fix the two ends of the metal pipe at this time, and the shielding plate 9 no longer hinders the metal pipe.

[0039] Further, the control mechanism comprises the damping plate 7 and two electromagnetic blocks 44, the two electromagnetic blocks 44 are arranged in the spline shaft 38 near the end of the spline groove 6 through the groove, one side wall of one of the two electromagnetic blocks 44 is fixedly connected with the damping plate 7, and the two electromagnetic blocks 44 repel each other magnetically.

[0040] When the single-chip microcomputer controls the two electromagnetic blocks 44 to be powered off, when the electromagnetic blocks 44 lose magnetism, at this time, the metal pipe loses the clamping action of the two damping plates 7, and falls to the bottom end of the mounting plate 21 and is soaked in the electrolytic tank 16.

[0041] Further, the upper surface of the arc-shaped plate 10 near one end of the discharging frame 27 is fixedly connected with the guide plate 5.

[0042] Through the arranged guide plate 5, the metal pipe can be conveniently rolled on the upper surface of the arc-shaped plate 10.

[0043] Further, the bottom of the base 23 is connected with a spraying mechanism for spraying the surface of the metal pipe of the robot, the spraying mechanism comprises the electrolytic tank 16 and two rotating shafts 19, the two rotating shafts 19 are rotatably installed on the side wall of the arc-shaped plate 10 through the mounting block, the two rotating shafts 19 are fixedly connected with the circular plates 15 on the opposite surfaces, the electrodes 12 are fixedly connected to the middle parts of the two circular plates 15, the supporting plates 13 are fixedly connected to the side walls of the two circular plates 15, the second gears 18 are fixedly connected to the opposite ends of the two rotating shafts 19, the electrolytic tank 16 is fixedly connected to the upper surface of the base 23, the two second racks 17 are fixedly connected to the side walls of the electrolytic tank 16, the two second racks 17 are respectively engaged with the two second gears 18, and the outer wall of one of the two rotating shafts 19 is connected with the trigger mechanism.

[0044] When the installation plate 21 is downwardly arc deflected, the second gear 18 can be driven along the second rack 17 to rotate the rotating shaft 19 due to the meshing of the second rack 17 and the second gear 18. When the articulated rod 30 moves to the side close to the receiving frame 20 and is horizontal, when the rotating shaft 19 reaches the lowest point, the supporting plate 13 is rotated to be perpendicular to the arc surface of the arc plate 10 at this time, at this time, the contact switch on one side of the sliding block 32 is contacted by the push rod 33, the control mechanism works to make the metal pipe lose the clamping effect of the two damping plates 7, so as to conveniently roll to the bottom end of the installation plate 21 and be soaked in the electrolytic tank 16, and be supported by the supporting plate 13 at this time, at this time, the spraying process can be completed by electrifying the electrodes 12 at both ends.

[0045] Further, the trigger mechanism comprises a push rod 33 and a fixed strip 34, the push rod 33 is fixedly connected to the outer wall of the rotating shaft 19, and the fixed strip 34 is fixedly installed on one of the installation blocks close to the push rod 33, and the side wall of the fixed strip 34 is provided with a contact switch.

[0046] When the rotating shaft 19 reaches the lowest point, the supporting plate 13 is rotated to be perpendicular to the arc surface of the arc plate 10 at this time, at this time, the contact switch on one side of the sliding block 32 is contacted by the push rod 33 on the rotating shaft 19, and the contact switch is extruded to start working.

[0047] Further, the upper surface of the base 23 is further fixed with a receiving frame 20 for collecting the metal pipes after spraying.

[0048] When the spraying is completed, the motor 24 is continuously driven to work, the rotation of the articulated rod 30 can further drive the installation plate 21 to move upwardly in an arc shape and restore to the original position, in the process, when the installation plate 21 gradually restores to the original position, the meshing of the second rack 17 and the second gear 18 can realize that the rotating shaft 19 drives the supporting plate 13 to rotate, when the supporting plate 13 rotates to the upper surface of the metal pipe, the metal pipe loses the supporting effect of the supporting plate 13 at this time, and can fall into the receiving frame 20, so that the automatic material collecting process can be completed.

[0049] Working principle: the robot metal pipe surface spraying equipment, in use, first, a plurality of metal pipes to be processed are placed in the feeding channel 1, like Figure 3As shown, in operation, the motor 24 is started to drive the articulated rod 30 to rotate. Due to the limiting sliding action of the sliding groove 31 and the sliding block 32, and the rotating connection of the mounting plate 21, when the articulated rod 30 rotates counterclockwise and drives the sliding block 32 to slide in the sliding groove 31, the mounting plate 21 can be further deflected as a whole. When the articulated rod 30 is in a horizontal state and close to one side of the discharge frame 27, the mounting plate 21 swings to below the discharge frame 27 and presses the push switch 29 through the guide plate 5. At this time, the push switch 29 signal is transmitted to the single-chip microcomputer, and the single-chip microcomputer controls the first electric telescopic rod 3 to work, thereby driving the stop plate 4 to move downward and act on the upper surface of the metal pipe. At this time, the metal pipe overcomes the resistance of the rubber strip 28 and makes the rubber strip 28 deform, so that it falls to the upper surface of the arc-shaped plate 10 through the discharge frame 27. Due to the blocking action of the shielding plate 9, the metal pipe can be stopped on the upper surface of the arc-shaped plate 10. When the metal pipe rolls to the position of the shielding plate 9, the second electric telescopic rod 41 is driven to work by the single-chip microcomputer, and the second electric telescopic rod 41 drives the shielding plate 9 to separate to both sides, on the one hand, the shielding plate 9 gradually separates from the metal pipe wall, and on the other hand, the second piston plate 43 moves in the first piston sleeve 36 and compresses the air in the first piston sleeve 36 to enter the second piston sleeve 37. The second piston sleeve 37 further drives the spline shaft 38 to move to one end of the spline groove 6, so that the two damping plates 7 clamp and fix the two ends of the metal pipe. At this time, the shielding plate 9 no longer hinders the metal pipe;

[0050] Then, the motor 24 is driven to work again, so that the articulated rod 30 drives the sliding block 32 to slide in the sliding groove 31. At this time, the downward arc-shaped deflection of the mounting plate 21 makes the rotating shaft 19 enter the electrolytic cell 16. In this process, on the one hand, the push switch 29 loses the extrusion action of the guide plate 5, and the first electric telescopic rod 3 starts to drive the stop plate 4 to reset upward. At this time, the next metal pipe enters the discharge frame 27, which is convenient for realizing the automatic feeding process. On the other hand, due to the meshing action of the first gear 8 and the first rack 11, when the mounting plate 21 drives the first rack 11 to move in an arc, the rotation of the first gear 8 can be realized. When the first gear 8 drives the metal pipe to rotate as a whole, the clean cotton is arranged on the upper surface of the arc-shaped plate 10. At this time, the relative movement between the two can clean the outer wall of the metal pipe, thereby further improving the spraying quality;

[0051] When the installation plate 21 is downwardly arc deflected, the second gear 18 can be driven along the second rack 17 and rotate the rotating shaft 19 due to the meshing of the second rack 17 and the second gear 18. When the articulated rod 30 moves to the side close to the receiving frame 20 and is horizontal, when the rotating shaft 19 reaches the lowest point, the support plate 13 is rotated and perpendicular to the arc surface of the arc plate 10 at this time, the contact switch on one side of the slide block 32 is contacted by the push rod 33 at this time, the single-chip microcomputer controls the two electromagnetic blocks 44 to be powered off, when the electromagnetic blocks 44 lose magnetism, the metal pipe loses the clamping action of the two damping plates 7, and falls to the bottom of the installation plate 21 and is soaked in the electrolytic tank 16, and is supported by the support plate 13, and the spraying process is completed by the power supply of the electrodes 12 at both ends.

[0052] When the spraying is completed, the motor 24 is continuously driven to work, the rotation of the articulated rod 30 can further drive the installation plate 21 to move upwardly and restore to the original position, in the process, the meshing of the second rack 17 and the second gear 18 can rotate the support plate 13 by the rotating shaft 19, when the support plate 13 is rotated to the upper surface of the metal pipe, the metal pipe loses the support of the support plate 13 and falls into the receiving frame 20, so that the automatic material collecting process is completed, the contact switch on one side of the slide block 32 is separated from the push rod 33 at this time, the single-chip microcomputer controls the two electromagnetic blocks 44 to be powered on, so that the next process is normally carried out.

[0053] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
