[0003] The existing steel plate shaping device is to put the steel plate in and then have multiple groups of rollers with preset heights to perform roller pressing correction. When a steel plate with a large deformation amount is put in, due to the high pressure roller pressing correction, cracks may appear at the deformation position of the steel plate during the correction process, and then the cracked steel plate will be directly transferred to the next process or directly used, which will cause quality problems or cause certain safety hazards. Summary of the invention

[0004] In view of the deficiencies in the prior art, the present invention provides a steel plate leveling device and a use method thereof.

[0006] Its beneficial effect is that when the steel plate is being shaped, the corresponding roller pressure is used for roller shaping according to the degree of deformation of the steel plate, thereby reducing the phenomenon of cracks in the steel plate due to excessive roller pressure, thereby improving the quality of the flattening of the steel plate.

[0007] In the above scheme, preferably, the detection element can be a displacement sensor that directly displaces the value, or a sliding resistor that converts the displacement value into resistance.

[0008] In the above scheme, preferably, the roller groups are at least provided with groups, and conveying lines are provided at the front and rear positions of the plurality of roller groups, and the detection device is provided in coordination with the conveying lines behind the plurality of roller groups.

[0010] In the above scheme, preferably, the scanning device includes an upper scanning piece and a lower scanning piece, and the steel plate passes between the upper scanning piece and the lower scanning piece, and both scan the front and back sides of the steel plate for cracks.

[0011] In the above scheme, preferably, both the lower roller assembly and the upper roller assembly include power rollers, the rotation speeds of the two power rollers are the same and in opposite directions, and a high-frequency vibrator is provided in the power roller to drive the power roller to vibrate.

[0012] In the above scheme, preferably, the greater the change in the value measured by the detection component is, the smaller the current initially controlled by the central control unit to be output to the electromagnetic adsorption component is, and at the same time, the vibration frequency of the high-frequency vibrator is controlled to be greater.

[0013] A method for using a steel plate leveling device: S1: Place the steel plate on the conveyor line, which drives the steel plate to move. The detection device initially detects the deformation height of the steel plate and transmits the measured value to the central control unit.

[0014] S2: According to the measured value, the central control unit controls the power supply to the electromagnetic adsorption component, and at the same time, the power roller starts to rotate. The conveyor line drives the steel plate into the roller group, and the upper roller assembly rolls on the steel plate.

[0015] S3: After the steel plate completely passes through the roller group from one side, the power roller reverses, and the steel plate enters the roller group again from the other side, reciprocating in and out of the roller group. At the same time, at the beginning of each reciprocating cycle, the central control unit controls to increase the current value output to the electromagnetic adsorption component.

[0016] S4: When the steel plate passes through the detection device and the value change is within the set range in the central control unit, the reciprocating movement of the steel plate ends and the leveling of the steel plate is completed.

[0017] In the above scheme, preferably, in S3, at the end of each reciprocating cycle, the steel plate will enter the detection device, and then the current value output to the electromagnetic adsorption component is determined by the height change value.

[0026] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Figure 1-Figure 5 A steel plate leveling device includes a platform frame 1, a roller group 2, a detection device 3, a scanning device 4 and a central control unit. The entire equipment is supported on the ground by the platform frame 1, and the roller group 2, the detection device 3, the scanning device 4 and the central control unit are all arranged on the platform frame 1.

[0027] Three conveyor lines 11 are arranged on the platform frame 1. The conveyor line 11 is a belt line, and a support plate is arranged under the belt. Therefore, the steel plate placed on the conveyor line 11 can support and drive the steel plate to move. The platform frame 1 is sequentially provided with multiple roller groups 2, and the multiple roller groups 2 are combined to form a leveling component, and the leveling component is located between the first and second conveyor lines 11.

[0028] The forward and reverse rotation of the conveyor line 11 allows the steel plate to enter the leveling assembly from two directions of the leveling assembly, thereby achieving reciprocating entry of the steel plate into the leveling assembly.

[0029] The roller group 2 includes an upper roller assembly 22 and a lower roller assembly 21, both of which include a rotatable power roller 211. The lower roller assembly 21 is fixedly arranged on the platform 1, and the height of the roller surface is consistent with the height of the transport surface of the conveyor line 11. A limiting guide rod 212 is also arranged on the lower roller assembly 21. The upper roller assembly 22 includes a sliding block 221. The power roller 211 is rotatably arranged on the left and right sliding blocks 221. The sliding block 221 guides the limiting sliding arrangement on the limiting guide rod 212 of the lower roller assembly 21, and one end of a first elastic member 222 is arranged under the sliding block 221, and the other end is in contact with the lower roller assembly 21, and on the lower roller assembly 21 An electromagnetic adsorption component 23 is also provided and is located below the sliding block 221. The sliding block 221 is made of magnetic material. When the electromagnetic adsorption component 23 is energized, it can give the sliding block 221 a downward suction force. At the same time, electromagnetic adsorption components 23 are provided below the left and right sliding blocks 221, so that the upper roller assembly 22 can move downward smoothly. The upper roller assembly 22 moves downward to compress the first elastic component 222, and at the same time, the power roller 211 can press against the power roller 211 of the lower roller assembly 21. At the same time, by changing the current of the electromagnetic adsorption component 23, the pressure of the upper roller assembly 22 on the lower roller assembly 21 is changed, and the pressure applied to the steel plate is changed when the steel plate passes by.

[0030] A high-frequency vibrator is arranged inside the power roller 211. When the electromagnetic adsorption part 23 is energized, the high-frequency vibrator is energized synchronously. Therefore, when the steel plate passes through, the power roller 211 not only exerts a downward pressure on the steel plate, but also vibrates downward pressure, thereby accelerating the shaping process of the steel plate.

[0031] In the initial state, under the action of the first elastic member 222, the upper roller assembly 22 is not in contact with the lower roller assembly 21, and the robot or operator places the steel plate on the first conveyor line 11. At this time, the conveyor line 11 and the power roller 211 rotate synchronously, so that the steel plate can directly pass through the leveling assembly and enter the second conveyor line 11.

[0032] The detection device 3 includes a pressure roller 31 and a detection member. A second guide slot 12 is provided on the platform frame 1. Both ends of the roller shaft of the pressure roller 31 are respectively guided and slidably arranged in the second guide slot 12 and are located above the second conveyor line 11. One end of the second elastic member 311 is pressed on the left and right ends of the roller shaft of the pressure roller 31, and the other end is pressed on the upper end surface of the second guide slot 12, so that the surface of the pressure roller 31 is elastically pressed on the second conveyor line 11, and the detection member is arranged on the slot wall of the second guide slot 12. The detection member can be a displacement sensor that directly detects the up and down movement of the roller shaft of the pressure roller 31, or it can be a sliding rheostat. When it is a sliding rheostat, the sliding head is arranged on the pressure roller 31, and the line group barrel is fixed on the side wall of the second guide slot 12. When the pressure roller 31 moves up and down, the resistance value on the sliding rheostat changes, thereby realizing the identification of the displacement change value of the pressure roller 31.

[0033] When the steel plate enters the second conveyor line 11, one end of the steel plate touches the circular surface of the pressure roller 31, thereby lifting the pressure roller 31 upward. The recording starts from the initial lifting until the steel plate completely passes through and the pressure roller 31 presses on the conveyor line 11 again, and the recording ends. The detection device 3 transmits the measured value to the central control unit, and the central control unit analyzes the height change value of the steel plate according to the value. The larger the height change value, the more serious the deformation of the steel plate, and the smaller the height change value, the smaller the deformation of the steel plate.

[0034] Its working principle or usage is as follows: The operator places the steel plate on the first conveyor line 11. At this time, the central control unit controls the rotation of the conveyor line 11 and the power roller 211, so that the steel plate can directly pass through the leveling assembly and enter the second conveyor line 11. After entering the second conveyor line 11, the steel plate passes through the detection device 3, so that the central control unit obtains the height change value of the entire steel plate.

[0035] The central control unit includes a database, and the height change value of the steel plate corresponds to the corresponding current value input to the electromagnetic adsorption component 23. After obtaining the height change value, the central control unit first controls the conveyor belt 11 and the power roller 211 to reverse, so that the steel plate moves in the opposite direction and enters the roller group 2 again. The central control unit simultaneously energizes the electromagnetic adsorption component 23 and the high-frequency vibrator, thereby causing the upper roller assembly 22 to descend and vibrate and roll the steel plate that enters again. When the steel plate is completely moved out of the roller group 2 and is located on the first conveyor line 11, the central control unit controls the conveyor belt 11 and the power roller 211 to reverse again, so that the steel plate enters the roller group 2 again. When the steel plate is located on the second conveyor belt 11, a reciprocating rolling shaping is completed. At this time, the steel plate enters the detection device 3 again, and the detection device 3 measures the height change value of the steel plate again. At this time, the height change value decreases, thereby increasing the current delivered to the electromagnetic adsorption component 23, so that the upper roller assembly 22 has a larger pressing force, and the conveyor belt 11 and the power roller 211 are reversed again for a second reciprocating rolling shaping.

[0036] After the reciprocating roller shaping, when the height change of the steel plate reaches the interval range within the central control unit, the shaping is completed and no reciprocating shaping is performed.

[0037] During the whole process, the pressure of the upper roller assembly 22 on the steel plate increases from small to large. When the deformation of the steel plate increases, a smaller force is used to deform the steel plate. After the deformation decreases, a larger force is used to perform the shaping work, thereby reducing the cracking of the steel plate during the shaping process.

[0038] At the same time, the rotation speed of the conveyor belt 11 and the power roller 211 can be controlled during the whole process. When the deformation amount is large, the rotation speed of the conveyor belt 11 and the power roller 211 is slow. After the deformation amount becomes smaller, the rotation speed of the conveyor belt 11 and the power roller 211 is accelerated, thereby further reducing the cracking of the steel plate during the shaping process. Example 2

[0039] This embodiment makes the following further improvements on the basis of embodiment 1: Figure 1-Figure 6 Specifically, it also includes a scanning device 4, which includes an upper scanning element 41, a lower scanning element 42 and a cleaning roller group 43. The scanning device 4 is located between the second conveyor line 11 and the third conveyor line 11. The cleaning roller group 43 includes an upper cleaning roller brush 431 and a lower cleaning roller brush 432 fixedly arranged on the platform frame 1. The upper cleaning roller brush 431 and the lower cleaning roller brush 432 are both electrically controlled to rotate, and negative pressure holes are opened on the roller surfaces of both. During the process of rotating to clean the steel plate, the dust and particulate matter generated by the cleaning are extracted. The upper scanning element 41 and the lower scanning element 42 are arranged on the platform frame 1 and are located behind the cleaning roller group 43.

[0040] After the detection device 3 detects that the steel plate meets the requirements, the second conveyor line 11 sends the steel plate into the cleaning roller group 43, and the upper cleaning roller brush 431 and the lower cleaning roller brush 432 roll and brush the upper and lower surfaces of the steel plate. The steel plate continues to move backward, and the steel plate enters between the upper scanning component 41 and the lower scanning component 42. The upper scanning component 41 and the lower scanning component 42 scan the passed position, and the second conveyor line 11 and the third conveyor line 11 cooperate to make the entire steel plate pass through the scanning device 4 and be located in the third conveyor line 11.

[0041] The upper scanning component 41 and the lower scanning component 42 can be visual cameras, which perform visual scanning on the passing steel plates to identify whether there are cracks, or they can be infrared scanning, which identifies cracks through the difference in reflected waves. The upper scanning component 41 and the lower scanning component 42 transmit the scanned structure to the central control unit. When encountering a cracked steel plate, the central control unit reports an error to the operator, who handles it, or controls the robot to stack the cracked steel plate at the place of unqualified products. Example 3

[0042] This embodiment makes the following further improvements on the basis of embodiment 2: Figure 1-Figure 6 Specifically, after cracks are detected during scanning, the database in the central control unit is iteratively modified, that is, the current value input to the electromagnetic adsorption component 23 corresponding to the height change value is reduced, so as to reduce the shaping pressure value corresponding to the height change value, so that the new database is used in the subsequent steel plate shaping process, thereby further reducing the cracking of the steel plate during the shaping process.
