Two columns 201 are provided at both ends of the bottom of the cross beam 20. The cross beam 20 and the two columns 201 form an arch structure spanning above the steel pipe conveying device and the steel pipe clamping device. A horizontal guide rail 211 is provided horizontally between the mobile plate 21 and the cross beam 20, so that the mobile trolley drives the mechanical arm to move horizontally along the horizontal guide rail 211. A vertical guide rail 212 is provided vertically between the mobile plate 21 and the mechanical arm, so that the mechanical arm can move vertically along the vertical guide rail 212. The mechanical arm is driven to perform horizontal reciprocating motion along the horizontal guide rail 211 by the horizontal driving mechanism 22, and the mechanical arm is driven to perform vertical reciprocating motion along the vertical guide rail 212 by the vertical driving mechanism 23.

[0036] Specifically, the robot arm includes a robot arm body 24 and a support base 25 . The robot arm body 24 and the support base 25 are vertically arranged, and the vertical guide rail 212 is arranged between the moving plate 21 and the robot arm body 24 .

[0038] The steel pipe grabbing mechanism includes a flipping drive assembly 26, a grabbing assembly 28 and a flipping transmission assembly 27 arranged between the flipping drive assembly 26 and the grabbing assembly 28. The flipping drive assembly 26 cooperates with the flipping transmission assembly 27 to drive the grabbing assembly 28 to move.

[0039] The grabbing assembly 28 includes a rotating rod 280 and a plurality of clamping members arranged on the rotating rod 280. The plurality of clamping members are arranged on the rotating rod 280 at equal intervals along the length direction of the rotating rod 280. Each clamping member includes a lower clamping arm 281, an upper clamping arm 282, a clamping plate 283 arranged on the lower clamping arm 281, a clamping cylinder 284 fixed to the upper clamping arm 282 by screws, and an electromagnetic suction cup 285 connected to the clamping cylinder 284. One end of the lower clamp arm 281 and the upper clamp arm 282 are fixed to the rotating rod 280 by screw connection, the clamp plate 283 is fixed to the other end of the lower clamp arm 281 by screw connection, and the clamping oil cylinder 284 is fixed to the other end of the upper clamp arm 282 by screw connection. The clamping oil cylinder 284 has a telescopic rod, and the telescopic rod of the clamping oil cylinder 284 passes through the other end of the upper clamp arm 282 and is connected to the electromagnetic suction cup 285. The clamp plate 283 and the electromagnetic suction cup 285 are respectively located on the inner side of the lower clamp arm 281 and the upper clamp arm 282, and the clamp plate 283 and the electromagnetic suction cup 285 are opposite to each other. When the clamping oil cylinder 284 is working, the telescopic rod is extended; when the clamping oil cylinder 284 is not working, the telescopic rod is retracted. By driving the telescopic rod to extend through the clamping cylinder 284, the clamping plate 283 and the electromagnetic suction cup 285 are brought close to each other, so that the steel pipe 40 can be clamped between the clamping plate 283 and the electromagnetic suction cup 285. The clamping plate 283 can support the steel pipe 40, and the electromagnetic suction cup 285 provides magnetic force to adsorb the steel pipe 40.

[0040] Specifically, the flipping drive assembly 26 is a second drive motor, and the flipping transmission assembly 27 includes a gear box 271, two transmission plates 272, a pulley 1 273, a pulley 274 and a transmission belt 275. The flipping drive assembly 26 and the gear box 271 are installed on the mechanical arm by screws. The gear box 271 has a power input shaft and a power output shaft. The power input shaft is connected to the output shaft of the second drive motor. The two transmission plates 272 are arranged on opposite sides of the support seat 25. The power output shaft passes through the upper end of one of the transmission plates 272 and is connected to the pulley 1 273. The two ends of the rotating rod 280 are correspondingly rotatably connected to the lower end of the transmission plate 272. One end of the rotating rod 280 passes through the lower end of the transmission plate 272 and is connected to the pulley 2 274.

When the second drive motor is running, the power output by the second drive motor is transmitted to the rotating rod 280 through the gear box 271, the first pulley 273, the transmission belt 275, and the second pulley 274 in sequence, thereby driving the rotating rod 280 to rotate.

[0041] Preferably, the above-mentioned steel pipe baler also includes a controller, which realizes coordinated control of various mechanisms through the controller connected to the motor 13, the electric telescopic rod 36, the horizontal drive mechanism 22, the vertical drive mechanism 23, the flip drive assembly 26 and the clamping cylinder 284. The controller can be a commercially available PLC controller, which will not be described in detail here.

[0042] When the steel pipe baler of the utility model is used, the conveying roller 15 rotates under the drive of the motor 13 and conveys the steel pipe 40 to one side of the steel pipe clamping device; the horizontal driving mechanism 22 drives the mechanical arm to move horizontally along the horizontal guide rail 211 on the crossbeam 20, and after moving to the set position, the vertical driving mechanism 23 drives the mechanical arm to move vertically downward along the vertical guide rail 212, so that the grab assembly 28 falls. After the grab assembly 28 falls into place, the horizontal driving mechanism 22 continues to drive the grab assembly 28 to move forward, so that the steel pipe 40 on the conveying roller 15 enters between the lower clamping arm 281 and the upper clamping arm 282; then the clamping cylinder 284 works, the telescopic rod is extended, and the clamping plate 283 and the electromagnetic sucker 28 are clamped. 5 are close to each other, thereby clamping the steel pipe 40 between the clamping plate 283 and the electromagnetic suction cup 285; then the vertical drive mechanism 23 drives the mechanical arm to move upward along the vertical guide rail 212, and at the same time, the flip drive assembly 26 drives the rotating rod 280 to rotate 90 degrees, driving the lower clamping arm 281 and the upper clamping arm 282 of the grab assembly 28 to rotate 90 degrees to a vertical state; when the mechanical arm rises to the position, the horizontal drive mechanism 22 continues to drive the mechanical arm to move horizontally along the horizontal guide rail 211 on the crossbeam 20, and the mechanical arm stops moving after reaching the set position above the steel pipe platform 31. At this time, the telescopic rod of the clamping cylinder 284 shrinks, and the steel pipe 40 falls onto the steel pipe platform 31, thereby completing the transportation action of the steel pipe 40. Subsequently, the electric telescopic rod 36 on the steel pipe platform 31 is started, and the two clamping plates 32 are driven by the two electric telescopic rods 36 to move along the slide 34 to clamp the stacked steel pipes 40, and finally the staff can pack the steel pipes 40.
