Description

Technical Field

[0001] The present invention relates to the technical field of flatness detection, and particularly to a flatness detection mechanism and a detection method thereof. Background Art

[0002] In the whole process of sheet production and processing, the flatness of the sheet surface has a crucial impact on product quality. From the sheets used as wall and floor bases in building construction, to the shell sheets in the precision manufacturing of electronic devices, and then to various shaped sheets in the furniture industry, once there is a deviation in flatness, problems will frequently occur in subsequent application links. For example, uneven building sheets may cause wall cracking and floor hollowing. Poor flatness of electronic device sheets will affect the installation accuracy of internal components and reduce product stability. If there are bumps or depressions on furniture sheets, it will directly damage the overall aesthetics and comfort of use. In terms of detection means, laser detection technology has gradually emerged in the field of sheet flatness detection due to its advantages such as high precision and non-contact. However, current laser detection still faces many challenges in actual applications. When traditional detection methods are combined with laser detection, serious connection problems are exposed. In the past, during the feeding process of manual detection or early automated equipment, there was a lack of precise positioning and stable conveying mechanisms. When the sheet enters the laser detection area, it often shows position deviation, which makes the laser detector unable to comprehensively and accurately scan the sheet surface according to the preset path, resulting in missing or incorrect detection data and unable to fully utilize the high-precision advantage of laser detection. When it comes to the detection of the flatness of both sides of the sheet, the problem is even more prominent. Most existing equipment cannot achieve seamless cooperation between automatic turning and laser detection, and manual turning of the sheet is still required. This not only seriously affects the detection efficiency and increases labor costs, but also easily causes damage such as scratches and collisions on the sheet surface during manual operation, thereby affecting product quality. In addition, the existing detection system is disconnected from the sheet production line, and it is difficult to achieve automated and coherent operation from sheet offline to laser detection and then to subsequent processes, unable to meet the requirements of high-speed, high-efficiency, and intelligent production in modern industry. Therefore, developing a sheet flatness detection mechanism that can accurately position the feeding, automatically turn the sheet, perfectly adapt to laser detection, and at the same time closely connect to the production line has extremely important practical significance for promoting the high-quality development of the sheet production industry. Summary of the Invention

A conveying motor is fixedly provided on the upper end of the mounting plate, and one end of the output shaft of the conveying motor is fixedly connected to the rotating shaft of the roller. A guide plate is fixedly provided on the upper surface of the middle section of the workbench, and a unloading motor is fixedly installed on the outer surface of the guide plate, and one end of the output shaft of the unloading motor is fixedly connected to the unloading plate.

[0005] Preferably, the four corners of the support plate are provided with L-shaped concave corners, and the vertical projection of the support plate does not overlap with the vertical projection of the limiting plate at all, and the outer edge of the vertical projection of the support plate is in contact with the inner edge of the vertical projection of the limiting plate.

[0006] The above technical solution allows the support plate to be accurately positioned under the limit of the limit plate, ensuring that the plate placed on the support plate is stable in position during transportation and inspection. At the same time, the L-shaped concave angle provides a structural basis for the subsequent rotation of the flip plate and for cooperating with the flip plate to achieve automatic unloading.

[0007] Preferably, the lower surface of the flap is in contact with the upper end surface of the limiting plate, and the portion where the vertical projection of the flap does not overlap with the vertical projection of the limiting plate is consistent with the shape of the L-shaped concave angle of the supporting plate.

[0008] By adopting the above technical solution, when the lifting electric push rod pushes the lifting plate to lift the supporting plate, the flap can be smoothly flipped to let the plate pass, and during the process of the supporting plate descending and discharging, the flap can accurately cooperate with the L-shaped concave corner of the supporting plate to stably support the plate, prevent the plate from falling, and realize smooth automatic unloading.

[0009] Preferably, one end of the lifting plate facing the support plate is in contact with the lower surface of the support plate, and the push plate and the push rod are designed as a whole with a C-shaped opening, and the C-shaped openings of the push plate and the push rod are arranged toward the support plate, and the push rod is arranged opposite to the clearance groove, and the upper surface of the push rod is flush with the upper surface of the support plate, and the lower surface of the push rod is flush with the inner bottom surface of the clearance groove.

[0010] By adopting the above technical solution, the lifting plate can stably lift the supporting plate to ensure the stable position of the plate during the inspection process. The C-shaped design of the push plate and the push rod facilitates the pushing of the plate. The precise coordination between the push rod and the give way groove ensures that the push rod does not affect the normal movement of the supporting plate when pushing the plate, ensuring the smooth progress of the turning and feeding process and avoiding position deviation of the plate during operation.

[0014] By adopting the above technical solution, when unloading the plates, the figure-eight guide plate can play a good guiding role for the plates, so that the plates can slide smoothly from the workbench to the conveyor belt, avoiding the plates from offsetting or getting stuck during the unloading process, ensuring the smooth unloading process and achieving close connection with the subsequent processes of the production line.

[0015] A method for detecting a flatness detection mechanism, the method comprising the following steps: S1. Loading and positioning: The plate is placed accurately on the support plate along the inner surface of the limit plate at the upper end of the column. The feeding linear module is started to drive the feeding base to move along the preset track. The magnetic column on the feeding base firmly absorbs the support plate and transports the support plate carrying the plate to the designated position. S2. Single-side detection: After the support plate reaches the designated position, the lifting electric push rod is activated to push the lifting plate up. The lifting plate lifts the support plate, and the linear module is switched to drive the switching seat and the laser detector to move, so that the laser detector is aimed at the plate to perform single-side flatness detection; S3. Plate transfer and preparation for flipping: After the single-side inspection is completed, the lifting electric push rod drives the lifting plate to descend, the support plate resumes adsorption with the magnetic column, the push linear module drives the push plate and push rod to move, the push rod is inserted into the clearance slot of the support plate, and then the push electric push rod drives the push rod to move the plate upward in preparation for flipping; S4, automatic flipping: When the plate is driven by the push rod to the same height as the electric chuck, the flipping linear module drives the flipping motor, flipping head and electric chuck to move toward the plate. The electric chuck clamps and holds both ends of the plate. The push rod descends, and the flipping motor starts to drive the electric chuck to rotate, flipping the plate. Then the push rod moves up to resume supporting the plate, the electric chuck is released, and the flipping linear module drives the relevant components to reset. S5. Re-inspection: The electric push rod is lifted to drive the lifting plate to rise, so that the support plate rises and stably supports the plate again. The linear push module drives the push plate and push rod to retract. The linear module is switched to drive the laser detector to inspect the turned plate. S6. Unloading operation: After the inspection is completed, the feeding linear module drives the plate to move between the middle columns, the lifting electric push rod pushes the lifting plate to rise and lift the supporting plate, the flap is pressed and rotates to let the plate pass, and when the plate is lifted to a certain height, the flap flips over and resets, the lifting electric push rod drives the lifting plate to descend, and the flap passes through the four concave corners of the supporting plate to let the plate pass and support the plate. At the same time, the conveying motor and the unloading motor are started, the unloading motor drives the unloading plate to rotate and lift the plate, so that it slides toward the conveyor belt, and the conveying motor drives the conveyor belt to rotate and transports the plate to the designated position to complete unloading.

[0016] Compared with the prior art, the present invention has the following beneficial effects: the flatness detection mechanism: 1. The combination of the linear feeding module and the feeding base, combined with the guidance of the plate by the limit plate, can accurately transport the support plate and the plate placed on it to the specified position, solving the problem of plate position offset in the traditional loading process, allowing the plate to accurately enter the detection area of the laser detector, ensuring that the laser detector can perform a comprehensive and accurate scan of the plate surface according to the preset path, giving full play to the high-precision advantage of laser detection. At the same time, the magnetic column stably adsorbs the support plate on the feeding base to prevent the support plate from shaking during transportation, further ensuring the stability of the plate position and improving the accuracy of the detection data.

[0017] 2. The limiting structure composed of the column and the limiting plate plays a limiting role on the plate on the supporting plate. In conjunction with the flip plate, when the lifting electric push rod pushes the lifting plate to lift the supporting plate, the flip plate can be flipped under pressure to let the plate pass and then flipped downward to ensure that the plate can be stably taken away during the subsequent lifting plate falling for unloading, thereby achieving the purpose of automatic unloading.

[0018] 3. The electric push rod, push linear module, push plate and push rod work together to accurately push the plate on the support plate to the specified position, preparing for the subsequent inspection process. At the same time, it also avoids the plate position deviation that may be caused by manual operation. The push rod is set directly opposite the clearance slot, which can smoothly support the plate without affecting the downward movement of the support plate, ensuring the smoothness of the turning process; 4. The turning linear module can accurately control the position of the turning motor and the turning head, so that the electric chuck can accurately clamp the plate. The turning motor drives the turning head to rotate, thereby realizing automatic turning of the plate. Compared with traditional manual turning, it greatly improves the detection efficiency and reduces labor costs. At the same time, it avoids scratches, collisions and other damages to the plate surface during manual operation, effectively ensuring product quality. 5. The unloading motor drives the unloading plate to rotate, which can realize automatic unloading of the plate after the inspection is completed. It is closely connected with the subsequent processes of the production line, solving the problem of disconnection between the existing inspection system and the plate production line, and realizing the automated and coherent operation from the plate unloading to laser inspection and then to the subsequent processes, meeting the needs of modern industrial high-speed, efficient and intelligent production.

Loading and positioning: the plate is accurately placed on the support plate (8) along the inner surface of the upper limit plate (11) of the column (10), the feeding linear module (5) is started, and the feeding seat (6) is driven to move along the preset track, and the magnetic column (7) on the feeding seat (6) firmly adsorbs the support plate (8), and the support plate (8) carrying the plate is transported to the designated position; S2, single-side detection: After the support plate (8) reaches the designated position, the lifting electric push rod (13) is started, pushing the lifting plate (14) upward, and the lifting plate (14) lifts the support plate (8), and the switching linear module (2) drives the switching seat (3) and the laser detector (4) to move, so that the laser detector (4) is aligned with the plate to perform single-side flatness detection; S3, plate transfer and preparation for flipping: after the single-side inspection is completed, the lifting electric push rod (13) drives the lifting plate (14) to descend, the support plate (8) resumes adsorption with the magnetic column (7), the push linear module (16) drives the push plate (17) and the push rod (18) to move, the push rod (18) is inserted into the clearance groove (9) of the support plate (8), and then the push electric push rod (15) drives the push rod (18) to move the plate upwards in preparation for flipping; S4, automatic flipping: When the plate is driven by the push rod (18) to the same height as the electric chuck (22), the flipping linear module (19) drives the flipping motor (20), the flipping head (21) and the electric chuck (22) to move toward the plate, and the electric chuck (22) clamps and holds both ends of the plate. The push rod (18) descends, and the flipping motor (20) starts to drive the electric chuck (22) to rotate, thereby flipping the plate. After that, the push rod (18) moves upward to resume supporting the plate, the electric chuck (22) is released, and the flipping linear module (19) drives the relevant components to reset; S5, re-test: lift the electric push rod (13) to drive the lifting plate (14) to rise, so that the support plate (8) rises and stably supports the plate again, the push linear module (16) drives the push plate (17) and the push rod (18) to retract, and the switch linear module (2) drives the laser detector (4) to detect the turned plate; S6, unloading operation: After the detection is completed, the feeding linear module (5) drives the plate to move between the middle columns (10), the lifting electric push rod (13) pushes the lifting plate (14) to rise and lift the supporting plate (8), the flip plate (12) is pressed and rotated to pass the plate, and when the plate is lifted to a certain height, the flip plate (12) flips and resets, the lifting electric push rod (13) drives the lifting plate (14) to descend, and the flip plate (12) passes through the supporting plate (8) through the four concave corners of the supporting plate (8) to support the plate. At the same time, the conveying motor (26) and the unloading motor (28) are started, and the unloading motor (28) drives the unloading plate (29) to rotate and lift the plate, so that it slides down to the conveyor belt (25), and the conveying motor (26) drives the conveyor belt (25) to rotate, and the plate is conveyed to the designated position to complete unloading.
