The placement table 7 is fixedly connected to the load-bearing base 8 through the frame assembly 9. The load-bearing base 8 bears the total weight of the entire device and the workpiece placed on the device. The larger bottom area can prevent the ground from being crushed due to excessive pressure after the device is placed. The placement table 7 The side of the placing table 7 is fixedly connected with a side guard plate 701, and the side guard plate 701 is fixedly connected to the load-bearing base 8 through the support frame 906 below. The lower surface of the placing table 7 is provided with criss-cross structural reinforcement plates 702, and the structural reinforcement plates 702 are located between the side guard plates 701. The structural reinforcement plates 702 are fixedly connected to the placing table 7 and the side guard plates 701. Because the placing table 7 does not need to be disassembled, it is usually fixed by welding, so that the placing table 7 becomes a structurally stable whole with a higher load-bearing capacity and can carry heavier processing objects.

[0044] The detection mechanism 1 and the moving mechanism 2 are located on the left and right sides of the placement table 7, and do not affect the structural form of the placement table 7. The placement table 7 can maintain its own structural strength. The detection mechanism 1 is used to detect the flatness of the component on the placement table 7. The detection mechanism 1 includes a lifting plate A105. A telescopic rod A106 is arranged between the lifting plate A105 and the load-bearing base 8. Generally, an electric telescopic rod is adopted to ensure the accuracy of height adjustment. An optical distance sensor 101 and a photosensitive element 102 are arranged on the lifting plate A105. The optical distance sensor 101 can emit and receive light waves of a specific frequency. The coordinates of the uneven parts on the component can be calculated by using the time interval between reflection and reception. The photosensitive element 102 is similar to the electronic film of a camera, and can receive the specific frequency light emitted by the optical distance sensor 101 to record the contour of the component, so as to determine whether the flatness of the component meets the standard. The optical distance sensor 10 1 is symmetrical with the photosensitive element 102 about the placement table 7, the transmitting end of the optical distance sensor 101 is directly opposite to the receiving end of the photosensitive element 102, the light source emitted by the optical distance sensor 101 is not a ray of light, but a light cone, the two cooperate with each other, the photosensitive element 102 determines whether the component is straight by judging whether the received light strip is connected, and the optical distance sensor 101 determines the position of the protrusion on the component by judging the reflection time of the light strip, the load-bearing base 8 is provided with guide rails A103 on the left and right sides of the lifting plate A105, the lifting plate A105 is provided with a slide groove A107 on the side of the guide rail A103, the slide groove A107 cooperates with the guide rail A103 to form a sliding pair, so that the height of the optical distance sensor 101 and the photosensitive element 102 relative to the placement table 7 can be smoothly and synchronously adaptively adjusted, and a limit plate A104 is provided on the upper end of the guide rail A103 to limit the maximum adjustment stroke.

[0045] The brake mechanism 5 is used to restrain the components on the placement table 7 when the pressure mechanism 6 is working. The frame assembly 9 includes a stand 901 fixedly connected to both sides of the placement table 7. The detection mechanism 1 is close to the front and rear sides of the stand 901. Usually, the detection mechanism 1 is set on the front and rear sides of the stand 901 to detect the straightness of the frame before correction and the straightness of the component after correction respectively. The upper end of the stand 901 is fixedly connected to the crossbeam 902, and the pressure mechanism 6 is movably connected to the crossbeam 902 to press the component to a straight state by applying pressure. The front and rear sides of the stand 901 are fixedly connected to the configuration frame 905. The brake mechanism 5 is set on the configuration frame 905. The brake mechanism 5 includes a fixed The brake rod 502 on the frame 905 is generally a cylinder. The movable end of the brake rod 502 points to the placement table 7 and is fixedly connected to the brake plate 501. The brake plate 501 can move up and down relative to the placement table 7 under the drive of the brake rod 502. When it is found that the straightness of the component is unqualified, the brake plate 501 will drop to press the component onto the placement table 7, which can effectively prevent the component from moving when the pressure mechanism 6 applies pressure to the component. The pressure mechanism 6 includes a hydraulic cylinder 601, which can generate a large pressure effect under the drive of a plunger pump. Two limit plates C602 are fixedly connected to the side of the cylinder of the hydraulic cylinder 601. The two limit plates C602 are respectively located above and below the crossbeam 902. The bottom is used to constrain the hydraulic cylinder 601 on the beam 902. The limit plate C602 located above the beam 902 is provided with a roller 609 in the rolling groove 608. The roller 609 is suitable for converting the sliding friction between the limit plate C602 and the beam 902 into rolling friction. The limit plate C602 located below the beam 902 will be in close contact with the beam 902 when the pressure mechanism 6 applies pressure. The strong friction force can effectively avoid the shaking of the pressure mechanism 6 and improve the working stability. The movable end of the hydraulic cylinder 601 points to the placement table 7 and is fixedly connected with the pressure head 604 through the nut 603. The pressure head 604 can be disassembled. The lower end of the pressure head 604 is pinned A pressure end 605 is fixedly connected to facilitate disassembly and installation of the pressure end 605, so as to flexibly cope with protrusions of different sizes on the component. The beam 902 has a sliding cavity 903 that passes through the upper and lower parts for the pressure mechanism 6 to move. The pressure mechanism 6 passes through the sliding cavity 903 and is slidably connected to the beam 902. The lower surface of the limit plate C602 below the beam 902 is fixedly connected to a driver 606, which has a motor and a reducer structure inside. The output end of the driver 606 is fixedly connected to a gear 607, and the lower surface of the beam 902 is fixedly connected to a spur rack 904, which meshes with the gear 607, and can well ensure the accuracy of position control.

[0046] The moving mechanism 2 is used to adjust the position of the component on the placement table 7. The moving mechanism 2 includes a linkage frame 210 to ensure that multiple migration components 220 rise and fall synchronously. A telescopic rod B211 is arranged between the linkage frame 210 and the load-bearing base 8. A cylinder is usually used to have a higher response speed. A migration component 220 is arranged on the linkage frame 210. There are two groups of migration components 220, each group has two, and the migration components 220 in each group are symmetrical about the placement table 7. The two groups of migration components 220 are respectively located in the front and rear of the stand 901 and around the placement table 7, which can well ensure the stability of the component when it is lifted. The optical distance sensor 101 and the photosensitive element 102 in the detection mechanism 1 are located between the stand 901 and the migration component 220, so that the detection mechanism 1 is closer to the working position of the pressure mechanism 6. In this way, when the detection mechanism 1 finds When there are uneven parts on the components, the position adjustment error of the components can be reduced to a smaller extent. The load-bearing base 8 is fixedly connected with a guide rail B213, which is located on the left and right sides of the linkage frame 210. A slide groove B214 is provided on the side of the guide rail B213 facing the migration component 220. The constraint plate 221 is fixedly connected with a slider 223 on the side of the guide rail B213 facing the slider 223 and the slide groove B214 form a sliding pair. Similarly, the synchronization and stability of the migration component 220 when rising and falling can be ensured. The upper end of the guide rail B213 is fixedly connected with a limiting plate B215, which also limits the maximum stroke of the migration component 220 moving up and down. The migration component 220 is provided with a crawler 222 for pushing the components on the placement table 7. When the migration component 220 is located at the lowest initial position, the crawler 222 does not contact the components.When the migration component 220 rises, the crawler 222 will contact the component and provide the component with an upward support force and a horizontal friction force, so that the component can be translated in the horizontal direction after leaving the upper surface of the placement table 7. The linkage frame 210 includes a pair of support frames 216, and the two support frames 216 are fixedly connected by a bridge frame 212 to form a linkage structure, which can rise and fall synchronously. The two ends of the telescopic rod B211 are respectively fixedly connected to the bridge frame 212 and the load-bearing base 8. The telescopic rod B211 does not require very high position control accuracy and generally uses a cylinder or hydraulic cylinder 601 to drive the linkage frame 210 to adjust up and down. The migration component 220 includes a lifting plate B226 fixedly connected to the support frame 216, and a pair of constraint plates 221 are fixedly connected to the lifting plate B226 to constrain the self-motion of the crawler 222. According to the degree, a smooth support plate 228 and a pair of rollers 230 are arranged between the two constraint plates 221. The smooth support plate 228 is located between the two rollers 230 and is used to provide a certain lifting force for the crawler 222. The two ends of the roller 230 are fixedly connected with a rotating shaft 232 through a limit ring 231. The constraint plate 221 is provided with an axial hole 227. The rotating shaft 232 and the axial hole 227 form a rotating pair. The outer side of the constraint plate 221 is fixedly connected with a servo motor 225 through a motor mounting plate 224. The rotating shaft 232 passes through the axial hole 227 and is fixedly connected to the output end of the servo motor 225 to provide rotational power for the roller 230. There is a through slot 229 between the smooth support plate 228 and the lifting plate B226. The crawler 222 passes through the through slot 229 and bypasses the two rollers 230. The roller 230 drives the crawler 222 to rotate synchronously. ;

[0047] The operating table 3 is used for manual operation and setting, such as setting the acceptable range of the flatness of the component, inputting the component thickness and the upper limit of the pressure of the pressure-applying mechanism 6. The distribution box 4 is provided with an electronic control system, a hydraulic system, and even a pneumatic system, which are used to provide motion control and power for the entire correction equipment. The electronic control system is used to be electrically connected to the optical distance sensor 101, the photosensitive element 102, the driver 606 and the electric telescopic rod to obtain detection signals and provide electrical energy, while the hydraulic system is mainly connected to the plunger pump and the hydraulic cylinder 601, and is configured with valve body structures such as a reversing valve and a relief valve, which control the hydraulic cylinder 601, the air cylinder and other moving parts in the correction equipment under the action of a manual or electric control valve.

[0048] The working principle of the component flatness correction device is as follows: when in use, the plate-shaped component is placed on the placement table 7, the migration component 220 rises, the track 222 contacts the lower surface of the component and lifts the component off the placement table 7, and then the component approaches the detection mechanism 1 at the entrance of the pressure mechanism 6 under the rotation of the track 222, and the optical distance sensor 101 generates light of a specific frequency band to scan the component and project the contour of the upper surface of the component onto the photosensitive element 102. If the protrusion on the component exceeds the flatness requirement, the photosensitive element 102 can be separated from the light source contour and simultaneously reflect the light back to the receiving end of the optical distance sensor 101. The time interval between emission and reception is used to calculate the coordinates of the protrusion on the component. Multiple uneven positions may be detected at one time, and these positions will be marked as coordinates that need to be corrected and sorted according to the time of discovery. In this way, the component continues to move under the pressure mechanism 6 Move forward, and at the same time, the pressure mechanism 6 will also move to the first target position driven by the driver 606 until the first marked protrusion on the component is located directly below the pressure mechanism 6, and the migration component 220 descends, and the component will naturally be placed flat on the placement table 7, and then the pressure head 604 will descend to apply pressure to the protrusion of the component to make it straight, and then, under the coordinated action of the migration component 220 and the driver 606, continue to correct the next coordinate point until all marks are fully pressed, the pressure head 604 rises to the initial position, and the migration component 220 rises again to lift the component from the placement table 7, and the corrected part will pass through the detection mechanism 1 between the pressure station exits and receive another flatness test. If it is qualified, it will pass. If there are still uneven parts due to obstruction, the coordinates of the uneven parts will be re-determined, and then return to the pressure position for correction again.
