[0019] Preferably, the leveling steps of the automatic leveling sheet material skew roller leveling machine are as follows:

[0020] S1. The material, initial bending state and thickness of the board are measured by using a camera and a laser displacement sensor, and the acquired data is sent to the data collection module. The data collection module then sends the data to the main processor module. The main processor module sends instructions to control the PLC controller to control the actuator based on the acquired data, and then controls the adjustment component to adjust the angle of the inclined roller.

[0024] S5. The arrangement of the first guide roller and the second guide roller helps to improve the stability of the plate during movement. The diameter of the first guide roller and the second guide roller, which guide the plate to move, is the same as the diameter of the inclined roller body, which helps to improve the leveling stability.

[0025] Preferably, step S1 further includes the following steps:

[0026] S11. By using a camera and a laser displacement sensor to measure the material, initial bending state, and thickness of the board, the main processor module automatically adjusts the extension and retraction of the hydraulic telescopic cylinder based on the acquired board data, thereby ensuring that the board receives uniform and stable pressure during the leveling process.

[0027] Compared with the prior art, the beneficial effects of the present invention are:

[0028] 1. This invention uses a camera and a laser displacement sensor to measure the material, initial bending state, and thickness of the board, and sends the acquired data to a data collection module, which then sends it to a main processor module. The main processor module sends instructions based on the acquired data to control the PLC controller to control the actuator, thereby controlling the adjustment component to adjust the angle of the inclined roller and improve the leveling effect.

[0029] 2. This invention uses a camera and a laser displacement sensor to measure the material, initial bending state, and thickness of the board material. The main processor module automatically controls the extension and retraction of the hydraulic telescopic cylinder based on the acquired board material data, thereby ensuring that the board material receives uniform and stable pressure during the leveling process and improving the leveling effect of the board material.

[0030] 3. The present invention uses a first servo motor to drive the threaded rod to rotate, which can adjust the position of the slider in the groove. The movement of the slider can drive the first rotating shaft to move. Through the setting of the through groove, the limiting block, the first connecting block and the second rotating shaft, the angle of the inclined roller body can be adjusted, thereby achieving different leveling effects and improving the practicality of the inclined roller leveling machine.

[0031] 4. By incorporating an arc-shaped groove, a fixed sleeve, and a fixed plate, this invention enables the fixed sleeve and fixed plate to move as the drive box moves with the angle of the inclined roller body. The second servo motor then drives the second transmission gear to rotate, which in turn drives the gear transmission chain and multiple first transmission gears to rotate. Furthermore, the second bearing, driven rod, and fixed sleeve ensure that the rotation of the first transmission gear drives the driven rod and the first helical gear to rotate, which in turn drives the second helical gear and the inclined roller body to rotate. This allows for the adjustment of the inclined roller body angle while maintaining the stability of the inclined roller rotation. Attached Figure Description

[0067] Working principle: Camera 1 and laser displacement sensor 2 measure the material, initial bending state, and thickness of the board material, respectively. The acquired data is sent to data collection module 4, which then transmits it to main processor module 5. Main processor module 5, based on the acquired data, sends instructions to PLC controller 7 to control actuator 8, which in turn controls the adjustment components to adjust the angle of the inclined roller, improving the leveling effect. Main processor module 5 automatically controls the extension and retraction of hydraulic telescopic cylinder 12 based on the acquired board material data, ensuring uniform and stable pressure on the board during leveling, thus improving the leveling effect. The first servo motor 14 drives the threaded rod 15 to rotate, adjusting the position of slider 16 within the groove 17. The movement of slider 16 drives the first rotating shaft 18. Through the through groove 20, limit block 21, first connecting block 19, and second rotating shaft 28, the angle of the inclined roller body 24 can be adjusted to achieve different leveling effects, improving the usability of the inclined roller leveling machine. The practicality of the system is achieved through the arrangement of the arc groove 30, the fixed sleeve 29, and the fixed plate 31. When the drive box 22 moves with the angle change of the inclined roller body 24, it can drive the fixed sleeve 29 and the fixed plate 31 to move. The second servo motor 37 drives the second transmission gear 36 to rotate, which in turn drives the gear transmission chain 35 and multiple first transmission gears 34 to rotate. Furthermore, through the arrangement of the second bearing 32, the driven rod 33, and the fixed sleeve 29, the rotation of the first transmission gear 34 can drive the driven rod 33 and the first helical gear 38 to rotate. The rotation of the first helical gear 38 can drive the second helical gear 39 and the inclined roller body 24 to rotate. Thus, while adjusting the angle of the inclined roller body 24, the stability of the inclined roller rotation can be ensured. The arrangement of the first guide roller 44 and the second guide roller 46 helps to improve the stability of the material movement. Moreover, the diameter of the first guide roller 44 and the second guide roller 46, which guide the material movement, is the same as the diameter of the inclined roller body 24, which helps to improve the leveling stability.

7. A leveling method for an automatic leveling sheet metal inclined roller leveling machine according to any one of claims 1-6, characterized in that, The leveling steps of this automatic leveling sheet metal inclined roller leveling machine are as follows: S1. The material, initial bending state and thickness of the board are measured by using a camera (1) and a laser displacement sensor (2), and the acquired data is sent to the data collection module (4), and then sent to the main processor module (5) through the data collection module (4). The main processor module (5) sends instructions to control the PLC controller (7) to control the actuator (8) according to the acquired data, and then controls the adjustment component to adjust the angle of the inclined roller. S2. The first servo motor (14) drives the threaded rod (15) to rotate, which can adjust the position of the slider (16) in the groove (17). The movement of the slider (16) can drive the first rotating shaft (18) to move. Through the setting of the through groove (20), the limiting block (21), the first connecting block (19), and the second rotating shaft (28), the angle of the inclined roller body (24) can be adjusted. S3. By setting up the arc groove (30), the fixed sleeve (29) and the fixed plate (31), when the drive box (22) moves with the angle change of the inclined roller body (24), it can drive the fixed sleeve (29) and the fixed plate (31) to move, thereby ensuring the stability of the inclined roller rotation while adjusting the angle of the inclined roller body (24). S4. The second servo motor (37) drives the second transmission gear (36) to rotate, which can drive the gear transmission chain (35) and multiple first transmission gears (34) to rotate. Then, through the setting of the second bearing (32), driven rod (33) and fixed sleeve (29), the rotation of the first transmission gear (34) can drive the driven rod (33) and the first helical gear (38) to rotate.
