The angle of the hook is consistent with the angle of the hopper slope, so that the material can be automatically picked up and conveyed. The structure is simple and practical, and the continuity and stability of feeding are achieved. (3) In order to solve the problem that the material with oil is easy to stick to the hopper wall, we installed a silo wall vibrator (intermittent operation) on the outside of the hopper slope, and cleverly designed ribs on the inside of the slope. The spacing of each rib is greater than the thickness of the material and smaller than the diameter of the material, which reduces the contact area between the material and the hopper. (5) The material is driven to rotate by the rotation of the disc. After passing the first rib plate, it encounters a spring, so that the material is conveyed to the side under the action of the spring. After reaching the discharge part, under the action of the triangular block, the vertical material is forced to fall down and lie flat due to the distance between the triangular block and the disc, and then it is output from the discharge track to the next workstation in turn. The whole process is fully automated and controlled, and the operation is stable and reliable. No human intervention is required, which saves time and effort, improves work efficiency, and saves labor costs.

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.

[0027] like Figure 1-10 As shown, the wire drawing die automatic cleaning intelligent sorting production line of the present invention comprises an automatic feeder 1, a material cleaning mechanism 2, a turntable leveling conveyor 3, an online purge device 4 and an intelligent detection and sorting device 5,

[0028] The turntable leveling conveyor 3 includes a frame 6, a rotating disc mechanism arranged on the frame 6, and a leveling cylinder frame mounted on the rotating disc mechanism. The rotating disc mechanism includes a disc 7 and a power device 8 for driving the disc 7 to rotate. The leveling cylinder frame is divided into a feeding part 10, a material side part 11, a discharging part 12, and a return part 13 by four rib plates 9. The square in the middle is sealed with a cover plate. The four rib plates 9 have through holes 14 for allowing materials to pass through at one end away from the center of the leveling cylinder frame and close to the disc. A spring 15 is provided in the edge portion 11 of the material. Specifically, in order to be more stable, a single spring 15 is too thin. The spring 15 is a U-shaped compression spring. The closed end of the spring 15 is installed at the center of the leveling cylinder frame, and the open end is close to the edge of the leveling cylinder frame. A triangular block 16 and a discharging track 17 for leveling are provided near the edge in the discharging portion 12. The distance between the bottom surface of the triangular block 16 and the upper surface of the disc 7 is less than the diameter of the material and greater than the thickness of the material. The triangular block 16 requires a certain hardness and needs to be heat treated during manufacturing. An arc frame 43 is also provided between the triangular block 16 and the discharge track 17 for guiding the material that has not successfully entered the discharge track 17 to the return part 13. The distance between the bottom surface of the arc frame 43 and the upper surface of the disc 7 is less than the diameter of the material and greater than the thickness of the material. The angle formed by the rib plate between the discharge part 12 and the return part 13 and the surface of the triangular block 16 away from the discharge track 17 is smaller than the angle formed between the rib plate and the surface of the arc frame 43 away from the discharge track 17. Four supporting devices 44 are circumferentially provided on the lower surface of the disc 7. The supporting devices 44 are installed on the frame 6. The supporting devices 44 are frustum-shaped rollers for facilitating the rotation of the disc 7.

[0029] The automatic feeding machine 1 includes a hopper 18 and a chain conveyor. The hopper 18 has a first feed port 19 and a first discharge port 20. The hopper 18 also has a slope 21 for gathering the material in the hopper 18 to the first discharge port 20. The chain conveyor is provided with a plurality of conveying plates, each of which is provided with a hook 22. The chain conveyor includes a first conveying portion 23 in the vertical direction and a second conveying portion 24 on an uphill slope. The first conveying portion 23 is directly opposite to the first discharge port 20; the angle of the hook 22 is consistent with the angle of the slope 21; a silo wall type vibrator 25 is provided on the outer side of the slope 21 of the hopper 18; a plurality of ribs 26 are provided on the inner side of the slope 21 from top to bottom, and the distance between adjacent ribs 26 is greater than the thickness of the material and less than the radius of the material. The material is placed into the hopper 18 from the first feed port 19. Under the influence of gravity, the material gathers toward the bottom of the hopper 18 and toward the first discharge port 20 along the inclined surface 21. The material is squeezed onto the hook 22. Since the angle of the hook 22 is inclined upward, the material is not easy to fall. After the chain conveyor is turned on, the first conveying part 23 and the second conveying part 24 continuously transport the material on the hook 22 to the second feed port 27 of the material cleaning mechanism 2.

[0030] The material cleaning mechanism 2 includes a second feed port 27, an ultrasonic rough cleaning section 28, an ultrasonic fine cleaning section 29, an ultrasonic rinsing section 30, a drying section 31 and a second discharge port 32 in sequence, wherein the second feed port 27 is connected to the conveying end of the second conveying section 24, and the second discharge port 20 is opposite to the feed section 10 of the turntable leveling conveyor; the ultrasonic rough cleaning section 28, the ultrasonic fine cleaning section 29 and the ultrasonic rinsing section 30 here all adopt a rotating drum type cleaning method, and a spiral guide groove is provided in the rotating drum. While the drum rotates for cleaning, the material will be automatically transported forward, and the speed is adjustable and controllable. After multiple spraying, the material meets the cleanliness requirements. Therefore, the device is a purchased existing finished product technology, so it will not be elaborated in detail.

[0031] The online purge device includes a linear feed conveyor 33 and a purge mechanism. The conveying start end of the linear feed conveyor 33 is connected to the discharge track 17.

The second purge device 35 is arranged beside the first purge device 34. The second purge device 35 includes a fixed bracket and a second high-pressure nozzle 50. The nozzle of the second high-pressure nozzle faces the conveying surface of the linear feed conveyor 33. During the second purge, the first manipulator 46 grabs the material and then the second high-pressure nozzle 50 performs the purge. The purpose of using high-pressure air twice to blow the die holes of the material is to remove the residual water film and dirt in the die holes, reduce sorting errors, and ensure the accuracy of subsequent inspection and sorting work.

[0032] The intelligent detection and sorting device 5 includes a detection part and a sorting and packing part located on one side of the detection part. The detection part includes a detection point 36, a transfer point 37 and a first manipulator 46 that grabs the material from the second purge device 35 to the detection point 36 for detection and transfers it to the transfer point 37.

A trolley 42 with a plurality of material boxes 41 with different apertures is provided below the second linear guide 39. The trolley 42 is arranged between the two first linear guides 38 and can be pulled out from the two first linear guides 38. The transfer point 37 is located at the edge of the sorting and packing part and also between the two first linear guides 38. The second purge device 35, the detection point 36 and the transfer point 37 are successively on the same straight line and the straight line is parallel to the first linear guide rail 38. The detection part also includes a linear module 45, which is installed on one side of the second purge device 35, the detection point 36 and the transfer point 37. The first manipulator 46 is installed on the linear module 45 and slides along the linear module 45.

[0033] During operation, the first manipulator 46 grabs the material and performs the second purge in the second purge device 35. After the purge, it is transported to the detection point 36 to measure the diameter of the material using the diameter gauge and the information is fed back to the controller. After the diameter measurement, the material is transported to the transfer point 37 and put down. The first manipulator 46 returns to the starting point; at the same time, the second manipulator 40 grabs the material at the transfer point 37 and puts the material into the material box 41 of the corresponding aperture according to the execution instruction of the controller. This cycle repeats over and over again. The two groups of manipulators cooperate well and work efficiently. As for how the first manipulator 46 and the second manipulator 40 realize movement, it can be driven by a motor plus a lead screw or a synchronous belt, or by a cylinder. Since they are all existing conventional technologies, they will not be elaborated in detail. In addition, the material boxes 41 on the trolley 42 are pre-arranged according to the aperture size. From left to right, the aperture of the material box 7 is small to large, or from right to left, the aperture of the material box 7 is small to large. As long as the order is preset, the preset information is written into the control system, and it can be loaded once, and it does not need to be set every time.
