[0004] While the above documents can improve work efficiency to some extent, they still have the following shortcomings:

[0005] When the working rollers are used to level the mirror aluminum plate, the surface of the working rollers may be damaged, making the surface rough. As a result, the moving path of the mirror aluminum plate is not straight during the rotation of the working rollers, which leads to poor leveling effect and may also damage the surface of the mirror aluminum plate. Summary of the Invention

[0006] In view of the above situation and to overcome the defects of the prior art, the present invention provides a precision leveling device and leveling method for mirror aluminum plates, which effectively solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a precision leveling device for mirror aluminum plates, comprising two symmetrically arranged bodies, with an array of electric push rods distributed between the two bodies, the two ends of which are fixedly connected to opposite sides of the two bodies respectively.

[0008] The end of the machine body is rotatably connected to a working roller via a first rotating shaft. The end of the working roller is provided with a leveling gear. The outer side of the leveling gear is connected to an external drive device, which is located inside the machine body. A cleaning component is provided on the side of the working roller.

[0009] The cleaning assembly includes hollow cleaning rollers arranged in an array inside the machine body. Each cleaning roller has bristles on its surface and a detection and adjustment component on its surface. One end of each cleaning roller has an exhaust pipe extending through the machine body and connected to the cleaning roller. The exhaust pipe's end extending through the machine body has a suction component. The other end of each cleaning roller is fixedly connected to a limiting gear located inside the machine body. The machine body has a slot for the limiting gear to rotate. The end of the limiting gear near the cleaning roller is flush with the end of the slot near the cleaning roller. A fixed rotating shaft extending through the machine body is fixedly connected to the end of the fixed rotating shaft located on the side of the working roller, away from the limiting gear. A driven gear is meshed with the outer side of the driven gear. The driven gear is fixedly connected to a drive shaft on a motor fixedly connected to the outer wall of the machine body.

[0010] Preferably, a first sprocket and a second sprocket are fixedly connected to the outer wall of the fixed rotating shaft distributed on the machine body. The first sprocket and the second sprocket are both located at the end of the fixed rotating shaft that extends out of the machine body. The first sprockets are connected to each other by a first chain drive, and the second sprockets are connected to each other by a second chain drive.

[0011] Preferably, the air extraction assembly includes a side box fixedly connected to the side of the machine body. The side box has an array of insertion holes that are rotatably and sealed to the exhaust pipe. The side box has a filter screen located below the insertion holes inside. An air extraction pipe is fixedly connected to the bottom side of the side box. The top of the side box has a cleaning port, and a baffle is inserted into the cleaning port.

[0012] The surface of the cleaning roller is provided with an array of suction holes, which are connected to the side box.

[0013] Preferably, an exhaust fan is fixedly connected to the end of the exhaust pipe away from the side box, and the end of the exhaust fan is connected to the front box through a connecting pipe. The front box is fixedly connected to the end of the machine body, and an array of air nozzles is provided at the opposite ends of the two front boxes.

[0014] Preferably, the detection and adjustment assembly includes limiting grooves formed on the surface of the cleaning roller and arranged in an array, a limiting block is slidably connected inside the limiting groove, a top block is fixedly connected to the top of the limiting block, a magnetic block is provided inside the limiting block, and a detection device is provided at the bottom of the limiting block to drive the limiting block to move up and down along the limiting groove.

[0015] The air intake holes are located on the periphery of the top block.

[0016] Preferably, the detection device includes an electromagnet disposed at the bottom of the limiting groove, an elastic element fixedly connected to the top of the electromagnet, the top of the elastic element being fixedly connected to the bottom of the limiting block, and the height of the elastic element being less than the depth of the limiting groove.

[0017] Preferably, the control valve is located inside the air intake hole, and a suction cup is fixedly connected to the end of the air intake hole.

[0018] Preferably, the center of the cleaning roller and the center of the working roller are located on the same plane; after the limiting block contacts the top of the limiting groove, the top block on the cleaning roller located on the side of the working roller contacts the outer wall of the working roller.

[0019] Preferably, a pad block is fixedly connected to the end of the top block away from the limiting block.

[0020] The present invention also provides a method for leveling a mirror-finish aluminum plate, the leveling method being implemented using a precision leveling device for mirror-finish aluminum plates, the leveling method comprising:

[0021] Step 1: Control the electric push rod to retract, thereby adjusting the distance between the upper and lower parts of the machine body, so that the height of the space between the upper and lower parts matches the thickness of the mirror aluminum plate to be corrected.

[0022] Step 2: Push the mirror aluminum plate between the two machine bodies from the side closest to the front box. After the mirror aluminum plate comes into contact with the working rollers in the upper and lower machine bodies, the working rollers in the upper and lower machine bodies rotate in opposite directions. Thus, after the mirror aluminum plate is inserted between the two working rollers, the mirror aluminum plate is leveled under the pressure of the two working rollers.

[0023] Step 3: After the mirror aluminum plate enters the space between the upper and lower machine bodies, the cleaning roller continues to drive the mirror aluminum plate to run continuously. The cleaning roller cleans the stubborn impurities adhering to the surface of the mirror aluminum plate, keeping the mirror aluminum plate clean.

[0024] Step 4: The top block on the cleaning roller comes into contact with the outer surface of the mirror aluminum plate, so that while the cleaning roller is driving the mirror aluminum plate, the leveling results of the mirror aluminum plate after passing through the working roller are detected and corrected by the detection and adjustment components.

[0025] The technical effects and advantages of this invention are as follows:

[0026] 1. This invention, by setting up an elastic element and an electromagnet, allows the control system to obtain the state of the working roller by detecting the change in the contraction of the elastic element when the cleaning roller contacts the working roller. If the working roller is misaligned, the control valve in the suction hole is controlled to adjust it, so that when the working roller and the cleaning roller are transporting the aluminum plate, the suction hole generates a strong suction force to limit the transport direction of the aluminum plate. The control system obtains the result of the mirror aluminum plate after being leveled by the working roller by detecting the change in the contraction of the elastic element when the cleaning roller contacts the mirror aluminum plate, and controls the electromagnet and the control valve in the suction hole to make corresponding adjustments to the leveled mirror aluminum plate according to the detection results.

[0027] 2. This invention, by setting up an air extraction component, allows air to enter the cleaning roller through the air intake after the exhaust fan is turned on, carrying away the swept dust and preventing the dust from damaging the mirror aluminum plate, thus improving the leveling precision of the mirror aluminum plate. After being filtered by the filter screen, the dust is sprayed to the outside through the air nozzles. Because the air nozzles are tilted towards the side of the mirror aluminum plate that it enters, the air nozzles on both the upper and lower sides spray air at the mirror aluminum plate, blowing away the dust attached to the surface of the mirror aluminum plate, further preventing the dust from damaging the mirror aluminum plate and improving the leveling precision of the mirror aluminum plate.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0041] Reference Figures 1 to 10 As shown, a precision leveling device for mirror aluminum plates includes two symmetrically arranged machine bodies 1, with an array of electric push rods 2 distributed between the two machine bodies 1. The two ends of the electric push rods 2 are fixedly connected to the opposite sides of the two machine bodies 1, respectively.

[0042] The end of the machine body 1 is rotatably connected to a working roller 4 via a first rotating shaft 3. The end of the working roller 4 is provided with a leveling gear 5. The outer side of the leveling gear 5 is connected to an external drive device 9. The external drive device 9 is located inside the machine body 1. A cleaning component 6 is provided on the side of the working roller 4.

[0043] The cleaning assembly 6 includes hollow cleaning rollers 601 arranged in an array inside the machine body 1. Each cleaning roller 601 has bristles 602 on its surface. A detection and adjustment assembly 7 is provided on the surface of each cleaning roller 601. One end of each cleaning roller 601 has an exhaust pipe 603 that extends through the machine body 1 and is connected to the cleaning roller 601. An air extraction assembly 8 is provided at one end of the exhaust pipe 603 extending through the machine body 1. The other end of each cleaning roller 601 is fixedly connected to a limiting gear 604 located inside the machine body 1. The machine body 1 contains a mechanism for rotating the limiting gear 604. The end of the empty groove 605 near the cleaning roller 601 is flush with the end of the empty groove 605 near the cleaning roller 601. The end of the limiting gear 604 is fixedly connected to a fixed rotating shaft 606 that passes through the machine body 1. The end of the fixed rotating shaft 606 located on the side of the working roller 4 away from the limiting gear 604 is fixedly connected to a driven gear 611. The outer side of the driven gear 611 is meshed with a driving gear 612. The driving gear 612 is fixedly connected to the drive shaft of the motor 613 fixedly connected to the outer wall of the machine body 1.

[0044] Specifically, a first sprocket 607 and a second sprocket 608 are fixedly connected to the outer wall of the fixed rotating shaft 606 distributed on the body 1. The first sprocket 607 and the second sprocket 608 are both located at the end of the fixed rotating shaft 606 that protrudes from the body 1. The first sprockets 607 are connected to each other by a first chain 609, and the second sprockets 608 are connected to each other by a second chain 610.

[0045] Specifically, the air extraction assembly 8 includes a side box 801 fixedly connected to the side of the body 1. The side box 801 has an array of insertion holes 802 that are rotatably and sealed to the exhaust pipe 603. The side box 801 has a filter screen 803 located below the insertion holes 802 inside. The bottom side of the side box 801 is fixedly connected to an air extraction pipe 804. The top of the side box 801 has a cleaning port with a baffle inserted in it.

[0046] The surface of the cleaning roller 601 is provided with an array of suction holes 805, which are connected to the side box 801.

[0047] Specifically, an exhaust fan 806 is fixedly connected to the end of the exhaust pipe 804 away from the side box 801. The end of the exhaust fan 806 is connected to the front box 808 through a connecting pipe 807. The front box 808 is fixedly connected to the end of the body 1. Each of the two front boxes 808 has an array of air nozzles 809 at the opposite end.

[0048] Specifically, the detection and adjustment component 7 includes a limiting groove 701 formed on the surface of the cleaning roller 601 and arranged in an array. A limiting block 702 is slidably connected inside the limiting groove 701. A top block 703 is fixedly connected to the top of the limiting block 702. A magnetic block is provided inside the limiting block 702. A detection device is provided at the bottom of the limiting block 702 to drive the limiting block 702 to move up and down along the limiting groove 701.

[0049] The air intake 805 is located on the periphery of the top block 703.

[0050] Specifically, the detection device includes an electromagnet 704 set at the bottom of the limiting groove 701, an elastic element 705 fixedly connected to the top of the electromagnet 704, the top of the elastic element 705 fixedly connected to the bottom of the limiting block 702, and the height of the elastic element 705 being less than the depth of the limiting groove 701.

[0051] Specifically, the control valve inside the air intake 805 has a suction cup fixedly connected to its end.

[0052] Specifically, the center of the cleaning roller 601 and the center of the working roller 4 are located on the same plane; after the limiting block 702 contacts the top of the limiting groove 701, the top block 703 on the cleaning roller 601 located on the side of the working roller 4 contacts the outer wall of the working roller 4.

[0053] Specifically, a pad is fixedly connected to the end of the top block 703 that is away from the limit block 702.

[0054] This device has an internal control system that controls the operation of all electrical components within the device.

[0055] In the initial state, the control valve inside the intake port 805 is closed, meaning that the exhaust pipe 603 is connected to the outside through the intake port 805.

[0056] In use, the control system controls the electric push rod 2 to retract, thereby adjusting the distance between the upper body 1 and the lower body 1, so that the height of the space between the upper body 1 and the lower body 1 matches the thickness of the mirror aluminum plate to be corrected. Then, the control system activates the internal and external drive devices 9 and motor 613 of the upper and lower body 1. The external drive device 9 includes a motor fixedly installed inside the body 1. The output end of the motor is fixedly connected to a drive gear that meshes with the leveling gear 5. Both the drive gear and the leveling gear 5 are located in the groove opened inside the body 1. After the external drive device 9 is started, it drives the working roller 4 to rotate through the leveling gear 5.

[0057] After starting, motor 613 drives drive gear 612 to rotate. Drive gear 612 meshes with driven gear 611 on the cleaning roller 601 located on the side of working roller 4. Drive gear 612 drives fixed shaft 606 on cleaning roller 601 located on the side of working roller 4 to rotate via driven gear 611. During the rotation of fixed shaft 606, first sprocket 607 and second sprocket 608 are driven to rotate simultaneously. Since cleaning rollers 601 are arranged in an array inside the upper and lower machine bodies 1 respectively, and each cleaning roller 601 is provided with a fixed shaft 606, and each fixed shaft 606 is also provided with a first sprocket 607. The first sprocket 607 and the second sprocket 608 are connected by the first chain 609 and the second sprocket 608 are connected by the second chain 610. As the driving gear 612 drives the fixed shaft 606 on the side of the cleaning roller 601 of the working roller 4 to rotate through the driven gear 611, the first sprocket 607 and the second sprocket 608 on the fixed shaft 606 drive all the other fixed shafts 606 to rotate through the first chain 609 and the second chain 610 respectively. The fixed shafts 606 then drive all the cleaning rollers 601 to rotate synchronously.

[0058] It should be noted that the limiting gear 604 on the sweeping roller 601 is located inside the empty groove 605 and serves to limit rotation. The limiting gears 604 on each sweeping roller 601 are complementary and do not contact each other. The limiting gear 604 and the leveling gear 5 are also in a non-contact state. At the same time, the sweeping roller 601 located inside the lower body 1 has the same rotation direction as the working roller 4, and the sweeping roller 601 located inside the upper body 1 has the same rotation direction as the working roller 4. The rotation direction of the sweeping roller 601 located inside the lower body 1 and the working roller 4 is not the same as that of the sweeping roller 601 located inside the upper body 1 and the working roller 4.

[0059] During the process of the control system controlling the rotation of the external drive device 9 and the motor 613, the control system controls the electromagnet 704 to be energized. The electromagnet 704 generates magnetic poles that repel the magnetic block, thereby causing the electromagnet 704 to push the limiting block 702 to move towards the top of the limiting groove 701, and finally make the limiting block 702 contact the top of the limiting groove 701. At this time, the top block 703 extends out of the limiting groove 701, and the elastic element 705 is in a stretched state. The control system sets the deformation of the elastic element 705 at this time to a basic value.

[0060] During the rotation of the cleaning roller 601 and the working roller 4 located inside the same machine body 1, the outer wall of the working roller 4 contacts the end of the top block 703 away from the limiting block 702 (at this time, the electromagnet 704 is not energized). When the electromagnet 704 is energized, the length of the top block 703 extending out of the limiting groove 701 increases. Thus, during the rotation of the cleaning roller 601 and the working roller 4, after the top block 703 contacts the working roller 4, the working roller 4 exerts a hard squeeze on the top block 703. At this time, the control system can detect whether the working roller 4 has been deviated or damaged by detecting the deformation change of the elastic element 705 when the top block 703 contacts the working roller 4.

[0061] When the top block 703 contacts the working roller 4, the working roller 4 exerts a hard pressure on the top block 703. The top block 703, through the limiting block 702, presses the elastic element 705 towards the electromagnet 704, thereby causing the elastic element 705, which is stretched by the magnetic repulsion force, to be compressed and contracted. Since the top blocks 703 on the cleaning roller 601 are arranged in a rectangular array after the cleaning roller 601 is unfolded, the contact part between the cleaning roller 601 and the working roller 4 is a straight line.

[0062] The control system can determine the state of the working roller 4 by detecting the change in the amount of contraction of the elastic element 705 along a straight line when the cleaning roller 601 contacts the working roller 4. If the amount of contraction of the elastic element 705 along the straight line always changes within a stable range, it indicates that the surface of the working roller 4 is not damaged and there is no installation misalignment.

[0063] If the shrinkage of the elastic element 705 on the straight line remains within a proportionally varying range, it indicates that the working roller 4 is misaligned during installation with the machine body 1. By detecting the proportional range of the shrinkage of the elastic element 705, the tilt direction and tilt angle of the working roller 4 can be obtained. Assuming the tilt direction of the working roller 4 is from left to right, the shrinkage of the leftmost elastic element 705 on the straight line is the largest, while the shrinkage of the rightmost elastic element 705 is the smallest. By constructing a straight line with the shrinkage of the leftmost and rightmost elastic elements 705 as reference points, and then constructing a coordinate system with any point on this straight line, the offset angle of the working roller 4 can be calculated. After obtaining the offset angle and tilt direction of the working roller 4, the control system controls the suction hole 805 on the cleaning roller 601 to make... The corresponding adjustment involves partially opening the control valve inside the suction hole 805, effectively reducing the diameter of the suction port of the suction hole 805. Assuming the deflection direction of the working roller 4 is from left to right (lower on the left and higher on the right), the control system controls the opening degree of the control valve in the suction hole 805 on the cleaning roller 601 so that the suction port diameter of the left suction hole 805 on the cleaning roller 601 is the largest, and the suction port diameter of the right suction hole 805 on the cleaning roller 601 is the smallest. The suction port diameter of the suction hole 805 is adjusted based on the deflection degree of the working roller 4, thereby generating a strong suction force in the left suction hole 805 of the cleaning roller 601 when the working roller 4 and the cleaning roller 601 are transporting the aluminum plate. The suction cup on the suction hole 805 limits the transport direction of the aluminum plate. To prevent the aluminum plate from being tilted downwards by the working roller 4 due to the lower left end and higher right end of the working roller 4, which would cause the aluminum plate to be subjected to a tilting force to the right and thus shift to the right.

[0064] If the shrinkage of some elastic elements 705 on the straight line is in a stable range, while the shrinkage of other elastic elements 705 is in an unstable range, it indicates that the outer surface of the work roll 4 is damaged and needs to be stopped for maintenance. The location and depth of the damage on the surface of the work roll 4 can be obtained by the position of the elastic element 705 in the unstable range on the cleaning roll 601 and the deformation of the elastic element 705 in the unstable range.

[0065] After completing the status identification of the working roller 4, the control system controls the exhaust fan 806 to start. The exhaust fan 806 sucks the dust on the cleaning roller 601 inside the machine body 1 through the suction port 805. The exhaust fan 806 draws the dust on the cleaning roller 601 into the side box 801 through the exhaust pipe 603. The dust is filtered by the filter screen 803 and remains at the top of the filter screen 803. Air enters the front box 808 through the connecting pipe 807 and is sprayed to the outside through the air nozzle 809. The mirror aluminum plate to be straightened is inserted between the two machine bodies 1 from the side closest to the front box 808, so that the upper and lower surfaces of the mirror aluminum plate contact the working rollers 4 inside the upper and lower machine bodies 1 respectively. Since the air nozzles 809 are tilted towards the side where the mirror aluminum plate enters, the air nozzles 809 on the upper and lower sides spray air at the mirror aluminum plate, blowing away the dust attached to the surface of the mirror aluminum plate, thereby avoiding damage to the mirror aluminum plate by dust and improving the leveling precision of the mirror aluminum plate.

[0066] Then, the mirror aluminum plate is pushed into the space between the two machine bodies 1 from the side near the front box 808. After the mirror aluminum plate comes into contact with the working rollers 4 inside the upper and lower machine bodies 1, the working rollers 4 inside the upper and lower machine bodies 1 rotate in opposite directions. As the mirror aluminum plate is inserted between the two working rollers 4, it is leveled under the pressure of the two working rollers 4. While leveling the mirror aluminum plate, the two working rollers 4 drive the mirror aluminum plate to move into the space between the upper and lower machine bodies 1.

[0067] After the mirror aluminum plate enters the space between the upper and lower machine bodies 1, the cleaning rollers 601 inside the upper and lower machine bodies 1 continue to rotate, and the cleaning rollers 601 continue to drive the mirror aluminum plate to run continuously. The cleaning rollers 601 clean the stubborn impurities adhering to the surface of the mirror aluminum plate, keeping the mirror aluminum plate clean.

[0068] Since the top block 703 on the cleaning roller 601 is in contact with the outer surface of the mirror aluminum plate, the cleaning roller 601 can detect the leveling results of the mirror aluminum plate after passing through the working roller 4 through the detection and adjustment component 7 while driving the mirror aluminum plate.

[0069] The cleaning rollers 601 of the upper and lower machine bodies 1 are divided into four sections: section A, section B, section C and section D. After being leveled by the working roller 4, the mirror aluminum plate passes through section A, section B, section C and section D in sequence.

[0070] During the passage of the mirror aluminum plate through section A, since the top block 703 on the cleaning roller 601 is in an extended state, when the mirror aluminum plate passes through the cleaning roller 601 in section A, the upper and lower surfaces of the mirror aluminum plate respectively press the top block 703 on the cleaning roller 601 in the upper and lower machine bodies 1. The top block 703 presses the elastic element 705 through the limiting block 702, causing the top block 703 to move towards the bottom of the limiting groove 701. The control system detects the amount of contraction of the corresponding elastic elements 705 on the upper and lower cleaning rollers 601 when the top block 703 contacts the surface of the mirror aluminum plate (i.e., Figure 10 The amount of shrinkage of the top block 703 on the upper cleaning roller 601 and the corresponding top block 703 on the lower cleaning roller 601 can be used to obtain the result of the mirror aluminum plate after being leveled by the working roller 4.

[0071] If the amount of contraction of the elastic element 705 when the top block 703 on the upper cleaning roller 601 contacts the surface of the mirror aluminum plate is the same as the amount of contraction of the elastic element 705 when the top block 703 on the lower cleaning roller 601 contacts the surface of the mirror aluminum plate, it indicates that the section of mirror aluminum plate is in a stable state after being leveled by the working roller 4.

[0072] If the amount of contraction of the elastic element 705 when the top block 703 on the upper cleaning roller 601 contacts the surface of the mirror aluminum plate is inconsistent with the amount of contraction of the elastic element 705 when the top block 703 on the lower cleaning roller 601 contacts the surface of the mirror aluminum plate, it indicates that the section of the mirror aluminum plate is in an unstable state after being leveled by the working roller 4.

[0073] If the contraction of the elastic element 705 on the upper cleaning roller 601 and the contraction of the elastic element 705 on the lower cleaning roller 601 are both in a balanced and stable state, but the contraction of the elastic element 705 on the upper cleaning roller 601 is greater than that on the lower cleaning roller 601, it indicates that the mirror aluminum plate warps after being leveled by the working roller 4. At this time, the control system supplies a more appropriate current to the electromagnet 704 on the upper cleaning roller 601 located in section B. The current supply is based on the ratio of the contraction of the elastic element 705 on the upper cleaning roller 601 to the contraction of the elastic element 705 on the lower cleaning roller 601 in section A. This increases the repulsive force of the electromagnet 704 on the upper cleaning roller 601 on the magnetic block on the limiting block 702 in section B. As a result, when the mirror aluminum plate passes through section B, the top block 703 on the upper cleaning roller 601 exerts a strong pressure on the mirror aluminum plate, thereby correcting the warped part of the mirror aluminum plate.

[0074] If the shrinkage of the elastic element 705 on the upper part of the upper cleaning roller 601 is in a balanced and stable state with the shrinkage of the elastic element 705 on the upper part of the lower cleaning roller 601, while the shrinkage of the elastic element 705 on the upper part of the upper cleaning roller 601 is in a non-balanced and stable state, it indicates that after the mirror aluminum plate is leveled by the working roller 4, some areas of the mirror aluminum plate exhibit a phenomenon of one side being higher and the other side being lower.

[0075] Assuming the contraction of the elastic element 705 on the upper cleaning roller 601, which is in a non-equilibrium stable state, is greater than that on the lower cleaning roller 601, it indicates that after the mirror aluminum plate is leveled by the working roller 4, one area is in a stable state while another area is in a state where one side is higher than the other. At this time, the control system supplies a more appropriate current to the electromagnets 704 on the upper and lower cleaning rollers 601 and the corresponding elastic elements 705 in the B and A sections, so that the mirror aluminum plate, after entering the B section, is in a stable state corresponding to the A section, the top block 703 on the elastic element 705 is in a mirror-like state. The aluminum plate is clamped. For the cleaning roller 601 that has one side higher than the other, the control system controls the supply current to the electromagnet 704 on the upper cleaning roller 601 in section B. The supply reference is the ratio of the contraction amount of the elastic element 705 on the upper cleaning roller 601 in section A to the contraction amount of the elastic element 705 on the lower cleaning roller 601. This increases the repulsive force of the electromagnet 704 on the upper cleaning roller 601 in section B against the magnetic block on the limiting block 702. As a result, after the mirror aluminum plate passes through section B, the top block 703 on the upper cleaning roller 601 exerts a strong pressure on the mirror aluminum plate, thereby correcting the one-sided high and low part of the mirror aluminum plate.

[0076] After the mirror aluminum plate is corrected in section B, it enters section C. The cleaning roller 601 in section C has the same function as the cleaning roller 601 in section A, which is used to determine whether there is any deviation in the mirror aluminum plate after the correction in section B.

[0077] If the warping problem persists, assuming the mirror aluminum plate is warped towards the upper part of the machine body 1, when the mirror aluminum plate passes the cleaning roller 601 in section D, the control system controls the control valve in the suction hole 805 on the cleaning roller 601 of the lower part of the machine body 1 in section D to close, while the control valve in the suction hole 805 on the cleaning roller 601 in other areas opens to a certain extent. The degree of opening is based on the detected degree of warping, so that the suction hole 805 on the cleaning roller 601 in section D generates sufficient suction to correct the warping of the mirror aluminum plate through the suction cup on the suction hole 805.

[0078] If the problem persists where some parts are stable and others are uneven, then when the mirror aluminum plate passes through the cleaning roller 601 in section D, assuming the uneven part of the mirror aluminum plate is warped towards the upper body 1, the control system supplies more current to the electromagnets 704 on the elastic elements 705 of the corresponding upper and lower cleaning rollers 601 in sections D and C, ensuring the elasticity of the elements is in a balanced and stable state. This ensures that the top block 70 on the elastic element 705 is in a balanced and stable state after the mirror aluminum plate enters section D. 3. The mirror aluminum plate can be clamped. For the part that is higher on one side and lower on the other, the control system controls the control valve in the suction hole 805 on the cleaning roller 601 in the lower part of the machine body 1 to close, while the control valve in the suction hole 805 on the cleaning roller 601 in the other areas is opened to a certain extent. The degree of opening is based on the detected degree of one side being higher and lower on the other, so that the suction hole 805 on the cleaning roller 601 in the D section generates sufficient suction force to correct the warping of the mirror aluminum plate through the suction cup on the suction hole 805.

[0079] It should be noted that during the rotation of the cleaning roller 601, when the top block 703 on the cleaning roller 601 comes into contact with the surface of the mirror aluminum plate and the outer wall of the working roller 4, a pad is fixed at the end of the top block 703 away from the limiting block 702, so that it will not cause too much damage to the mirror aluminum plate and the working roller 4.

[0080] This invention also provides a method for leveling a mirror-finish aluminum plate. The leveling method utilizes a precision leveling device for mirror-finish aluminum plates and includes:

[0081] Step 1: Control the electric push rod 2 to retract, thereby adjusting the distance between the upper body 1 and the lower body 1, so that the height of the space between the upper body 1 and the lower body 1 matches the thickness of the mirror aluminum plate that needs to be corrected.

[0082] Step 2: Push the mirror aluminum plate between the two machine bodies 1 from the side near the front box 808. After the mirror aluminum plate comes into contact with the working rollers 4 inside the upper and lower machine bodies 1, the working rollers 4 inside the upper and lower machine bodies 1 rotate in opposite directions. As a result, after the mirror aluminum plate is inserted between the two working rollers 4, the mirror aluminum plate is leveled under the pressure of the two working rollers 4.

[0083] Step 3: After the mirror aluminum plate enters the space between the upper and lower machine bodies 1, the cleaning roller 601 continues to drive the mirror aluminum plate to run continuously. The cleaning roller 601 cleans the stubborn impurities adhering to the surface of the mirror aluminum plate and keeps the mirror aluminum plate clean.

[0084] Step 4: The top block 703 on the cleaning roller 601 comes into contact with the outer surface of the mirror aluminum plate, so that while the cleaning roller 601 drives the mirror aluminum plate to run, the detection and adjustment component 7 detects and corrects the leveling results of the mirror aluminum plate after passing through the working roller 4.

[0085] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
