DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] Embodiment 1:

[0034] like Figure 1-Figure 9As shown, the graphite electrode automatic detection and packaging device includes a feeding guide rail 1, a bottom supporting mechanism 3, a PLC controller 8, a first laser rangefinder 81, a second laser rangefinder 82 and a third laser rangefinder 83; the feeding guide rail 1 is arranged along the material conveying direction, the bottom supporting mechanism 3 is arranged below the feeding guide rail 1, and the first limiter 21 is arranged at the feeding end of the bottom supporting mechanism 3; the bottom supporting mechanism 3 includes a weighing platform 31, a second bearing plate 32, a third bearing plate 33, a second lifting member 34, a third driving motor 37, a roller 38 and a second fixed rod 39; a second bearing plate 32 is arranged above the weighing platform 31, a second lifting member 34 is arranged on the second bearing plate 32, the second lifting member 34 is arranged in a vertical direction, a third bearing plate 33 is arranged above the second lifting member 34, a second fixed rod 39 is arranged on the third bearing plate 33, and a second fixed rod 39 is arranged on the second fixed rod 39. Roller 38, the axis of roller 38 is arranged in the horizontal direction and perpendicular to the feeding direction, and the third drive motor 37 is connected to the roller 38 in transmission; first laser rangefinders 81 are respectively arranged on both sides of the feeding guide rail 1, and the detection ends of the two first laser rangefinders 81 are arranged facing each other; a second laser rangefinder 84 is arranged on the third bearing plate 33, and the detection end of the second laser rangefinder 84 is arranged vertically upward; the detection end of the second laser rangefinder 84 is located in the middle of the two groups of rollers 38; a third laser rangefinder 85 is arranged above the second laser rangefinder 84, and the detection end of the third laser rangefinder 85 is arranged vertically downward; the third drive motor 37 is electrically connected to the output control end of the PLC controller 8, and the weighing platform 31, the first laser rangefinder 81, the second laser rangefinder 84 and the third laser rangefinder 85 are electrically connected to the signal input end of the PLC controller 8 respectively.

[0035] The two ends of the large graphite electrode rod are respectively a threaded protrusion end and a threaded groove end, which are convenient for threaded splicing and connection in the later stage. Therefore, although the graphite electrode rod is an irregular cylindrical structure in shape, in fact, the threaded protrusion end can be just stuck into the threaded groove end. Therefore, its volume can be measured according to the approximate cylinder.

[0036] The graphite electrode rod is placed on the feeding guide rail 1. When the electrode rod passes through the two sets of first laser rangefinders 81, the two sets of first laser rangefinders 81 feed back the detection data to the PLC controller 8 for receiving and processing, and calculates the column height of the electrode rod (measures the edge height of the regular column); after that, when the electrode rod moves to the top of the bottom support mechanism 3, the PLC controller 8 outputs and controls the second lifting member 34 to extend upward, and the two sets of rollers 38 lift the electrode rod from the feeding guide rail 1. At this time, the cross-sectional center of the electrode rod body is aligned with the second laser rangefinder 84 and the third laser rangefinder 8. 5 are located on the same straight line, so the diameter of the cross-section circle of the electrode rod body can be detected by the second laser rangefinder 84 and the third laser rangefinder 85, and after being transmitted to the PLC controller 8 for receiving and processing, the volume of the electrode rod can be calculated; when the second lifting member 34 rises to the maximum position and stabilizes, the PLC controller 8 reads the weight signal of the weighing platform 31, records the weight of the electrode rod, and thus the density of the electrode rod body can be calculated and recorded; the density of a large electrode rod body can be measured quickly and conveniently, continuous work can be carried out, and the detection is convenient and fast with high accuracy.

[0037] The second lifting member 34 may be an electric telescopic rod or a hydraulic telescopic rod.

In the initial operation, the first limiter 21 is in the lifting state, and when the electrode rod moves to the first limiter 21, the first limiter 21 limits the electrode rod and stops moving; when the bottom support mechanism 3 is in the "no-load" state, the third limiter 23 is in the lifting state, the first limiter 21 slowly descends, and the electrode rod slowly rolls to the third limiter 23, and then the first limiter 21 is lifted again, and the bottom support mechanism 3 lifts the electrode rod again to perform the measurement operation; thereby realizing the continuous measurement operation of a single electrode rod body to prevent mutual interference.

The third lifting member 43 and the fourth telescopic member 44 can be an electric telescopic rod, a hydraulic telescopic rod or a pneumatic telescopic rod; when the bottom supporting mechanism 3 lifts the electrode rod body and completes the density measurement operation, the fourth telescopic member 44 extends, pushes the end power supply head 42 to the end of the electrode rod body and maintains contact, the third lifting member 43 extends, pushes the voltage measuring head 41 downward to the top of the electrode rod body and maintains contact, the PLC controller 8 outputs control power supply, and records the stable voltage difference between the two groups of voltage measuring heads 41, and then calculates the local resistance of the electrode rod body according to the distance between the two groups of voltage measuring heads 41, and then the PLC controller 8 outputs control to cut off the power supply, the fourth telescopic member 44 and the third lifting member 43 retract, the resistance measurement operation is completed, the bottom supporting mechanism 3 descends, and the electrode rod is transported to the next process.

[0048] Preferably, a second bidirectional lead screw 451, a fifth bearing plate 452 and a driving motor are arranged on the fixed crossbeam 45, and the driving motor is connected to the second bidirectional lead screw 451 in transmission. Two groups of third lifting members 43 are fixedly connected to the two nut seats of the second bidirectional lead screw 451 through the fifth bearing plate 452, respectively, so that the two groups of voltage measuring heads 41 can move toward or away from each other; thereby, resistance measurement can be performed on different points of the same electrode rod body, and the position of the voltage measuring head can be adjusted according to the actual size of the electrode rod body, thereby improving the use effect of the measuring mechanism.

[0049] Preferably, the roller 38 is an insulating roller.

[0053] The output of the PLC controller 8 controls the operation of the second driving motor 352 to adjust the distance between the two sets of rollers 38, thereby adjusting the size between the rollers according to the actual size of the electrode rod body to improve the adaptability of the mechanism.

[0054] Embodiment 6:

[0055] like Figure 1-Figure 9 As shown, with respect to the above embodiments, this embodiment optimizes the rope wrapping packaging structure.

[0056] In the graphite electrode automatic detection and packaging device, a first rope winding mechanism 5 is respectively arranged on both sides of the base support mechanism 3 and the feeding guide rail 1, and the first rope winding mechanism 5 includes a circular plate 51, a circular turntable 52, a second limit rod 53, a manipulator 54, a third clamping roller 56 and a sixth telescopic member 57; a sixth telescopic member 57 is arranged beside the base support mechanism 3, and the telescopic end of the sixth telescopic member 57 points to the upper side of the base support mechanism 3, and a circular plate 51 is fixedly arranged at the telescopic end of the sixth telescopic member 57.

The sixth telescopic member 57 can be an electric telescopic rod or a hydraulic telescopic rod.

[0057] The annular plate 51 and the annular turntable 52 are both hollow structures in the middle, leaving a channel for the electrode rod to enter and exit; the annular turntable 52 can be driven to rotate by the driving motor to drive the gear turntable; when the bottom support mechanism 3 holds up the electrode rod and completes the density and resistance measurement operation, the PLC controller 8 outputs and controls the sixth telescopic member 57 to extend, pushing the annular plate 51 toward the electrode rod, and the electrode rod passes through the annular plate 51, as shown in FIG. Figure 6After that, one end of the straw rope of the straw rope roll 91 passes through the third clamping roller 56 and is clamped by the manipulator 54; when the annular plate 51 moves to a suitable position, the manipulator 54 pulls the straw rope so that one end of the straw rope is located between the annular turntable 52 and the electrode rod body, and then drives the annular turntable 52 to rotate so that the second limit rod 53 contacts the straw rope, and under the traction of the second limit rod 53, the straw rope roll 91 is unwound, and after the annular turntable 52 has continuously rotated around the electrode rod body for more than 2 weeks, the manipulator 54 loosens one end of the straw rope and moves it to the outside of the annular turntable 52 (without affecting the movement of the second limit rod 53 and the traction of the straw rope); the straw rope initially wound on the electrode rod body is driven by the third drive motor 37 to drive the roller 3 8 rotates, thereby driving the electrode rod body to rotate, and the electrode rod body is continuously wound around the motor rod body under the continuous rotation, and during the rotation of the electrode rod body, the sixth telescopic member 57 slowly extends or contracts, so that the grass rope is wound around the electrode rod body; when the winding is completed, the manipulator 54 moves to the discharge end close to the third clamping roller 56, clamps the grass rope, and cuts the grass rope thereafter (at this time, the manipulator re-clamps one end of the grass rope, thereby providing a guarantee for the subsequent continuous grass rope winding operation); the sixth telescopic member 57 retracts to the initial state, and the bottom support mechanism 3 descends to transport the electrode rod after the grass rope is wound to the next process; and then the grass rope winding operation of the next electrode rod body is carried out, which is convenient and quick, and basically no manual operation is required.

[0058] Preferably, the second limiting rod 53 is a roller structure with a groove, and the roller can rotate around its axis, so that the second limiting rod 53 can reduce the friction with the straw rope when pulling the straw rope, thereby reducing the phenomenon of the straw rope being broken.

After the grass rope winding operation of an electrode rod is completed, the mechanical gripper 541 clamps the grass rope. In this process, the third position sensor 83 is used to detect the position of the grass rope. When the mechanical shear 542 cuts the grass rope, the third position sensor 83 detects that the grass rope is in a cut state, which is convenient for the PLC controller to output and control the first rope winding mechanism 5 to move to the side of the feeding guide rail.

[0062] Preferably, Figure 7 As shown in the figure, in the initial stage of winding of the straw rope, when the manipulator 54 clamps one end of the straw rope and moves to the inner side of the circular turntable 52, the clamping end of the manipulator 54 is in a "tilted downward" state, and a part of the straw rope can overlap with the movement path of the second limiting rod 53, so that when the second limiting member 53 forms traction on the straw rope and is wound on the electrode rod body, the straw rope is not entangled on the manipulator 54 as much as possible; or even if it is wrapped around the manipulator 54, since the clamping end of the manipulator 54 is set to be tilted downward, it is also convenient for the clamping end of the manipulator to be "pulled out" smoothly without affecting the subsequent operation of the manipulator.

[0072] Embodiment 10:

[0073] like Figure 1-Figure 9 As shown, for the above embodiments, this embodiment optimizes the laser marking structure.

[0074] In the present graphite electrode automatic detection and packaging device, a laser marking component 7 is arranged next to the base mechanism 3, and the laser marking component 7 includes a fourth drive motor 71, a fourth lead screw 72, a fourth fixed plate 73, a fourth limit rod 74 and a marking head 75; the fourth drive motor 71 is fixedly arranged, and the fourth drive motor 71 is drivingly connected to the lead screw nut of the fourth lead screw 72; the fourth fixed plate 73 is arranged parallel to the fourth lead screw 72, one end of the fourth limit rod 74 is fixedly connected to the fourth lead screw 72, and the other end is slidably connected to the fourth fixed plate 73; the fourth drive motor 71 is electrically connected to the output control end of the PLC controller 8.

[0075] During operation, after the bottom supporting mechanism 3 lifts the electrode rod body, the fourth driving motor 71 drives the nut seat of the fourth lead screw 72 to rotate, and the fourth lead screw 72 cannot rotate under the limitation of the fourth limiting rod 74 (a slide rail or a groove is provided on the fourth fixing plate 73, and the fourth limiting rod 74 is slidably connected to the slide rail or the groove), so it can only move laterally, and the fourth lead screw 72 pushes the marking head 75 to the vicinity of the electrode rod body, and the marking head 75 performs laser marking on the surface of the electrode (during the marking process, the third driving motor 37 drives the roller 38 to drive the electrode rod body to rotate, so as to facilitate the marking operation). After the marking operation, the fourth lead screw 72 retracts to complete the marking.

[0076] Preferably, a sixth bearing plate 76 is arranged at one end of the fourth lead screw 72 close to the base support mechanism 3, and a fifth lead screw 77 and a fifth drive motor 78 are arranged on the sixth bearing plate. The fifth drive motor 78 is transmission-connected to the fifth lead screw 77. The marking head 75 is arranged on the nut seat of the fifth lead screw 77. The fifth lead screw 77 is arranged along the vertical direction.
