Furthermore, video equipment is expensive, difficult to maintain, and has high environmental requirements. Some workshops operate in poor environments, with dust and lubricants on the equipment, significantly reducing visual quality over time.

DETAILED DESCRIPTION

[0023] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a simple pipe direction recognition device of the present invention in conjunction with the accompanying drawings.

[0024] like Figure 1-6 As shown, the utility model is a simple orientation recognition device for pipe fittings, comprising a workbench 1, with a material bin 2 at the front end of the workbench 1, a material feeding mechanism 3 below the material bin 2, material clamping and turning mechanisms 4 on both sides of the rear of the material feeding mechanism 3, an orientation recognition clamp mechanism 5 above the material clamping and turning mechanism 4, a material moving mechanism 6 below the material clamping and turning mechanism 4, and a punching mechanism 7 behind the material moving mechanism 6. All mechanisms are controlled by the device control system. Horizontally placed long square tube fittings 8 are stacked horizontally in the material bin 2, and the upper and lower surfaces of the square tube fittings 8 are different in width. The material feeding mechanism 3 is used to move the square tube fittings 8 one by one to the material clamping and turning mechanism 4. The material gripping and flipping mechanism 4 is used to grip the square tube 8 and move it to the upper orientation recognition clamp mechanism 5. This orientation recognition clamp mechanism 5 includes an orientation recognition die 51 that matches the smaller side of the square tube 8. The orientation of the square tube 8 is determined by whether the orientation recognition die 51 can hold the square tube 8 in place. If the square tube 8 is properly gripped, it is judged to be in the reverse direction. The material gripping and flipping mechanism 4 rotates the square tube 8 180 degrees to flip it. If the square tube 8 is not gripped in place, it is judged to be in the forward direction and no flipping is performed. Finally, the material moving mechanism 6 moves the square tube 8 to the bottom of the punching mechanism 7 for punching.

[0025] The material silo 2 includes a silo body 21 enclosed by baffles. A limit baffle 22 is located at the rear of the silo body 21, allowing only one row of pipes to pass through. A vertical chute 211 is located at the bottom of the silo body 21. The material feed mechanism 3 is located within the chute 211 and can move along the chute 211, driving the bottom row of square pipes 8 backward.

[0026] The material feeding mechanism 3 includes a screw 31, a slider 32, and a stop bar 33. The screw 31 is fixed below the bin body 21. The slider 32 is threadedly connected to the screw 31 and slides within the chute 211. The stop bar 33 is provided on the bottom surface of the bin body 21 and is fixedly connected to the slider 32. The screw 31 is driven by a motor to rotate, driving the slider 32 to move within the chute 211, thereby driving the stop bar 33 to push the square tube 8 backward and enter the material clamping and turning mechanism 4.

[0027] The material clamping and flipping mechanism 4 is fixedly mounted on the two side baffles. Both sides have the same structure and are used to symmetrically clamp the square tube fitting 8. Each side includes a Y-axis moving module 41, a Z-axis moving module 42, an X-axis moving module 43, a flipping module 44, a clamping mechanism 45, and an orientation sensor 46. The Y-axis moving module 41 is fixedly mounted on the two side baffles, the Z-axis moving module 42 is fixedly mounted on the Y-axis moving module 41, the X-axis moving module 43 is fixedly mounted on the Z-axis moving module 42, the flipping module 44 is fixedly mounted on the X-axis moving module 43, the clamping mechanism 45 is fixedly mounted on the flipping module 44, and the orientation sensor 46 is fixedly mounted on the flipping module 44, above the clamping mechanism 45. The clamping mechanism 45 is used to clamp the two ends of the square tube fitting 8. The clamping mechanism 45 preferably has two protruding columns that are used to insert into the hollow ends of the square tube fitting 8. Each module is controlled by a cylinder to extend or rotate. In the initial state, each moving module is in its initial position, and the clamping mechanism 45 is in a horizontal position. When the control system controls the material feeding mechanism 3 to move into position, the material clamping and flipping mechanism 4 is immediately activated. First, the X-axis moving module 43 is controlled to move, and the clamping mechanisms 45 at both ends are brought closer to clamp the square tube fitting 8. Then, the Z-axis moving module 42 is controlled to lift upward and approach the direction recognition clamping mechanism 5. Then, the flipping module 44 is controlled to flip 90 degrees. The direction recognition clamping mechanism 5 clamps the end face of the square tube fitting 8. The direction recognition sensor 46 identifies whether the direction recognition clamping mechanism 5 is clamped in place, thereby determining the front and back of the square tube fitting 8. If it is in the reverse direction, the flipping module 44 is controlled to rotate the square tube fitting 8 180 degrees to flip it. If it is in the forward direction, no flipping is performed. Finally, the Y-axis moving module 41 is controlled to move the square tube fitting 8 to the rear material moving mechanism 6. After completion, the material clamping and flipping mechanism 4 is reset.

[0028] The orientation recognition clamp mechanism 5 includes an orientation recognition mold 51 and an up-and-down moving module 52. The up-and-down moving module 52 is fixedly mounted on a side baffle and driven by a cylinder to move up and down. The orientation recognition mold 51 is fixedly mounted on the up-and-down moving module 52 and is driven to move up and down by the up-and-down moving module 52. The orientation recognition mold 51 has a clamping portion that matches the smaller side of the square tube fitting 8. When clamping the smaller side of the square tube fitting 8, it can clamp to the bottom, but cannot clamp to the bottom when clamping the larger side of the square tube fitting 8. When the material clamping and flipping mechanism 4 controls the square tube fitting 8 to move to the bottom of the orientation recognition mold 51, the up-and-down moving module 52 controls the orientation recognition mold 51 to move downward to clamp the square tube fitting 8. If the clamping is in place, the orientation recognition mold 51 can just move in front of the orientation recognition sensor 46. The orientation recognition sensor 46 sends a recognition signal, and the control system determines that it is reverse. If the clamping is not in place, the orientation-recognizing mold 51 cannot be moved to the front of the orientation-recognizing sensor 46, and the control system determines that it is in the positive direction. After completing one orientation recognition, the orientation-recognizing clamp mechanism 5 is reset.

[0029] The material movement mechanism 6 comprises a material placement seat 61, a lifting module 62, a translation module 63, and a material transfer bracket 64.

[0030] The jacking module 62 includes a jacking fixed base 621, a jacking cylinder 622, a vertical slide 623, and a jacking plate 624. The fixed base 621 is fixedly mounted on the workbench 1. The jacking cylinder 622 and the vertical slide 623 are vertically fixed to the jacking fixed base 621. The vertical slide 623 is fixed to both sides of the jacking cylinder 622. The middle of the jacking plate 624 is fixedly connected to the output end of the jacking cylinder 622, and the two ends are slidably connected to the vertical slide 623. The translation module 63 is fixedly mounted on the jacking plate 624. The jacking cylinder 622 rises and falls under the control of the control system, driving the translation module 63 to rise and fall.

[0031] The translation module 63 includes a translation mount 631, a translation cylinder 632, and horizontal slides 633. The translation mount 631 is fixedly mounted on the lifting plate 624, the translation cylinder 632 is fixedly mounted in the center of the translation mount 631, and the horizontal slides 633 are fixedly mounted on either side of the translation mount 631. The material transfer bracket 64 is fixedly connected to the output end of the translation cylinder 632 in the center and slidably connected to the horizontal slides 633 on either side. The translation cylinder 632 moves back and forth under the control of the control system, driving the material transfer bracket 64 back and forth.

[0032] The material transfer bracket 64 includes material clamping plates 641 on the left and right sides. The material clamping plates 641 have three groups of clamping parts, including clamping part 1 6411, clamping part 2 6412, and clamping part 3 6413. The three clamping parts are used to clamp the square tube fittings 8 to different workstations respectively.

[0033] After the square tube fitting 8 moves to the material placement seat 61, the control system controls the jacking module 62 to lift upward, the clamping part 6411 rises and holds the square tube fitting 8, and then controls the translation module 63 to move backward to move the square tube fitting 8 to the punching mechanism 7 at the rear.

[0034] The punching mechanism 7 comprises a punching device 71, a punching fixture 72, and a second material placement base 73. The punching device 71 is fixedly mounted on either side of the workbench 1 and punches holes at both ends of the square tube fitting 8. The punching fixture 72 comprises a punching fixture 721, a clamping cylinder 722, and a clamping block 723. The punching fixture 721 is fixedly mounted on either side of the workbench 1, below the punching device 71. The clamping cylinder 722 is fixedly mounted on the punching fixture 721. The clamping block 723 is fixedly mounted at the output end of the clamping cylinder 722, forming a clamping portion with the punching fixture 721. The second material placement base 73 is fixedly mounted on the workbench 1, behind the punching fixture 72. Driven by the material moving mechanism 6, the square tube fitting 8 moves to the punching fixture 72, where it is clamped and secured at both ends by the clamping cylinder 722. The control system then controls the punching device 71 to punch holes in the square tube fitting 8. After drilling is complete, the square tube 8 on the drilling fixture 72 is synchronously moved by the second clamping portion 6412 of the material transfer bracket 64 to the second material placement seat 73. A pipe guide rail 731 is fixedly mounted behind the second material placement seat 73. The square tube 8 on the second material placement seat 73 is synchronously moved by the third clamping portion 6413 to the guide rail 731. Driven by the material movement mechanism 6, the square tube 8 moves synchronously from the previous workstation to the next. After completing two steps, it slides down the guide rail 731 to the bottom of the workbench 1 for collection.
