Alternatively, the camera 61 may employ a CCD high-speed video camera or a CMOS high-speed video camera.
The polishing principle is described below by taking a metal bar made of iron as an example, wherein the rust removing solution can be a dilute hydrochloric acid solution.
Firstly, a metal bar to be processed is placed in the buffer bin 51, then a negative pressure pump 533 is started to convey gas to the interior of a communicating pipe 532, a corrugated pipe 534 is extended under the stamping of the gas, a push plate 531 is driven to slide leftwards until the push plate 531 pushes the metal bar in the buffer bin 51 to lean against one side of a baffle 541, at this time, a pressure sensor 543 detects pressure change, a signal is transmitted to a controller 7, a hydraulic rod 623 is started by the controller 7 to drive a piston 622 to move downwards through a transmission rod 624, and therefore a dilute hydrochloric acid solution stored in the dropper 621 is enabled to drop from a proper amount of a drop nozzle 6211 of the dropper 621 to the surface of the metal bar under the action of the pressure. Then, the hydraulic rod 623 is activated again to drive the piston 622 to move upward through the transmission rod 624, so that the dilute hydrochloric acid solution inside the dropper 621 does not flow out under negative pressure.
Then, the dilute hydrochloric acid solution on the surface of the metal bar is subjected to chemical reaction with rust, and the rust degree of the metal bar is judged by observing the reaction speed. If the rust degree on the surface of the metal bar is slight, the reaction is relatively slow, the generated bubbles are less, and the reaction speed is relatively slow; when the surface of the metal bar is rusted more seriously, the reaction speed of the metal bar and the dilute hydrochloric acid solution is higher, the reaction is very rapid and severe, a large amount of bubbles are generated, the generated bubbles are higher in speed, and the phenomena such as hissing and the like can be generated. The camera 61 is used for photographing and recording the reaction condition between the dilute hydrochloric acid solution and the metal bar, wherein the camera 61 can record the reaction process at a very high frame rate, the controller 7 can determine the strength of the reaction by analyzing the information recorded by photographing, and the rust degree of the surface of the metal bar is analyzed by analyzing the strength of the reaction between the dilute hydrochloric acid solution and the rust on the surface of the metal bar, so that the time length of polishing the metal bar is determined.
The correspondence relationship among the reaction intensity, the rust degree, and the polishing time period may be obtained experimentally and set in the controller 7.
Then, the controller 7 controls the multi-stage electric telescopic rod 522 to be started to be shortened, and drives the buffer bin 51 to move downwards to a position close to the first driving roller assembly 3 and the second driving roller assembly 4; then the controller 7 controls the electric push rod 542 to drive the baffle 541 to move upwards to avoid the metal bar; continued actuation of the negative pressure pump 533 causes the bellows 534 to continue to extend, driving the pusher 531 to slide to the left until the metal bar is slid out of the interior of the buffer bin 51 into the trough between the first drive roller assembly 3 and the second drive roller assembly 4.
When the metal bar is conveyed into the trough, the first driving roller assembly 3, the second driving roller assembly 4 and the polishing module 2 are started at the same time, the rotation direction of the driving roller 33 driven by the first motor 34 is the same as that of the driving wheels 43 driven by the second motor 44, friction force is generated between the driving roller 33 and the driving wheels 43 and the surface of the metal bar, the friction force can enable the metal bar to rotate along with the driving roller 33 and the driving wheels 43, and by means of a rolling transmission mechanism, the friction force and rolling characteristics between the driving roller 33 and the driving wheels 43 rotating in the same direction can enable the metal bar to rotate and simultaneously realize left-right lateral movement. Meanwhile, the third motor 35 drives the screw rod 36 to rotate, drives the first driving roller assembly 3 to move towards the second driving roller assembly 4, lifts the metal bar in the trough, enables the metal bar to be in contact with the polishing wheel 22, and the polishing wheel 22 is driven by the fourth motor 21 to rotate so as to polish and remove rust on the surface of the metal bar.
When the metal bar moves to one end of the driving roller 33, the controller 7 controls the first motor 34 to drive the driving roller 33 to rotate reversely, and the second motor 44 drives the driving wheels 43 to rotate reversely to drive the metal bar to move transversely reversely, so that polishing is continuously performed on the surface of the metal bar until the time of polishing the metal bar set by the controller 7 is reached.
In addition, in order to realize the stability of horizontal movement of the metal bar while rotating, two pushing components can be installed on the polishing table 1, wherein one pushing component is responsible for pushing the metal bar leftwards, and the other pushing component is responsible for pushing the metal bar rightwards. The pushing component can be composed of a motor, a screw pair and a pushing rod, the pushing rod is fixedly connected with a screw nut in the screw pair, the pushing rod is arranged opposite to the end face of the metal bar in the trough, when the motor drives the screw in the screw pair to rotate, the pushing rod is driven to move horizontally, and then the metal bar is pushed to move horizontally, and under the matched use of the two pushing components, the metal bar is pushed to move horizontally at a constant speed. The ball can be arranged on the pushing rod so as to reduce the friction force with the end face of the metal bar and avoid scratches.
It will be appreciated that during the polishing of the metal bar, the next metal bar can be inspected to improve the efficiency of the operation.
Further, the guard 8 is activated at the same time as the metal bar is polished. A certain amount of water is injected into the water storage box 813 of the water rack 81 in advance, the controller 7 controls the water pump 82 to start, the water pump 82 can pump and convey water in the water storage box 813 to the water outlet box 811, the water flows downwards from the hollowed-out holes 812 in the bottom of the water outlet box 811 and forms a water curtain in an overhead area in the middle of the water rack 81, when splashed sparks pass through the water curtain, the sparks can be quickly extinguished by the water curtain, and the sparks are prevented from being splashed to hurt workers or cause fire. The water in the water outlet box 811 directly falls into the water storage box 813 after flowing out, so that the water can be recycled.
In summary, the rust removing and polishing device for the surface of the metal bar uses the visual detection assembly 6 to detect the rust degree of the surface of the metal bar blocked by the blocking assembly 54 in the buffer bin 51, and the controller 7 determines the time length of polishing the metal bar according to the detection signal so as to control the polishing module 2, the first driving roller assembly 3 and the second driving roller assembly 4 to polish the surface of the metal bar together according to the corresponding time length, thereby ensuring the polishing effect of each metal bar and solving the problem that the rust removing and polishing effect is poor due to the unified treatment of the metal bars with different rust degrees in the prior art; the first driving roller assembly 3 is driven by the gap adjusting mechanism to slide back and forth on the polishing table 1 so as to change the gap between the first driving roller assembly and the second driving roller assembly 4, namely the width of a trough, so that the polishing device is suitable for metal bars with different diameters, and the practicability of the rust removing and polishing device for the surfaces of the metal bars is improved; meanwhile, the metal bar in the trough can be lifted to be in contact with the polishing wheel 22 by utilizing the front-back sliding of the first driving roller assembly 3, so that the polishing module 2 can polish the metal bar; the top of the polishing table 1 is also provided with the protection device 8 which is arranged opposite to the polishing wheel 22, and the water in the water storage box 813 is conveyed into the water outlet box 811 by the water pump 82, so that the water flows downwards from the hollowed-out holes 812 of the water outlet box 811 and forms a water curtain in an overhead area in the middle of the water frame 81, and the protection device is used for extinguishing sparks generated during polishing and preventing sparks from splashing to injure workers or cause fire.
