[0018] The following detailed, non-limiting description of the technical solution of the present invention, in conjunction with preferred embodiments and accompanying drawings, is provided. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0019] Please see Figure 1-10The present invention provides a technical solution including an operating table 1 and a controller on one side of the operating table 1. A conveying assembly 2 is provided on the top of the operating table 1. The conveying assembly 2 includes a first guide rail 201 and a second guide rail 202 fixedly installed on the top of the operating table 1. The first guide rail 201 and the second guide rail 202 are symmetrically arranged. A motor 203 is installed at one end of the first guide rail 201 and the second guide rail 202. A lead screw 204 is connected to the output end of the motor 203. A sliding block 205 is threadedly connected to the lead screw 204. A sliding groove 3 is opened on the top of the sliding block 205. A slider 4 is slidably connected to the top of the sliding groove 3. A hydraulic cylinder 5 is installed on the top of the sliding block 205. The output end of the hydraulic cylinder 5 is fixedly connected to the slider 4. A first electric push rod 6 is installed on the top of the slider 4. A connecting plate 7 is fixedly connected to the top of the first electric push rod 6. A rotating shaft 8 is connected to one side of the connecting plate 7 through a bearing. A clamping block 9 is fixedly connected to one side of the rotating shaft 8.

[0020] The controller controls the extension and retraction of the first electric push rod 6, adjusts the height of the connecting plate 7 and the clamping block 9 to fit the thickness of the material, and simultaneously controls the extension and retraction of the hydraulic cylinder 5 to push the slider 4 to move laterally along the slide groove 3, adjusting the distance between the two sets of symmetrically arranged clamping blocks 9 so as to match the size of the material and facilitate size adjustment according to the material size. The controller is electrically connected to the motor 203, and the motor 203 drives the lead screw 204 to rotate. Since the lead screw 204 is threadedly connected to the sliding block 205, and the sliding block 205 is guided and restricted by the first guide rail 201 and the second guide rail 202, the rotational motion of the lead screw 204 is converted into the linear motion of the sliding block 205 along the length of the guide rail, which can drive the upper rotating shaft 8 and the clamping block 9 to move horizontally.

[0021] A drive motor 10 is fixedly installed on the top of the connecting plate 7. The output end of the drive motor 10 is connected to a first pulley 11. One end of a belt body 12 is connected to the outside of the first pulley 11. The other end of the belt body 12 is connected to a second pulley 13. One end of the second pulley 13 is connected to the rotating shaft 8.

[0022] The controller is electrically connected to the drive motor 10. When the controller starts the drive motor 10, the drive motor 10 drives the first pulley 11 to rotate, which is transmitted to the second pulley 13 through the belt body 12. This drives the rotating shaft 8, which is fixedly connected to the second pulley 13, to rotate. The rotating shaft 8 is fixedly connected to the clamping block 9. When the rotating shaft 8 rotates, it drives the clamping block 9 and the clamped material to rotate synchronously.

[0023] A correction component 14 is provided on one side of the clamping block 9. The correction component 14 includes a hinge seat 1401 fixedly connected to the top of the inner side of the clamping block 9. A correction block 1402 is connected to one side of the hinge seat 1401 via a bearing. Two sets of second electric push rods 1403 are fixedly installed on the top of one side of the clamping block 9. The two sets of second electric push rods 1403 are hinged to the correction block 1402.

[0024] The controller is electrically connected to two sets of second electric push rods 1403. Since the second electric push rods 1403 are hinged to the straightening block 1402, and the straightening block 1402 is connected to the clamping block 9 through the hinge seat 1401, the extension and retraction of the second electric push rods 1403 causes the straightening block 1402 to swing horizontally around the hinge seat 1401. In the initial state, the straightening block 1402 is in a parallel state, and the inner side of the straightening block 1402 is in contact with the edge of the material. Through the differential extension and retraction of the two sets of second electric push rods 1403, the straightening block 1402 and the material are pushed to swing horizontally around the hinge seat 1401 until the material posture reaches the preset accuracy. The controller then stops the action of the second electric push rods 1403, thus completing the posture correction.

[0025] A first pressure sensor 15 is provided on the side of the straightening block 1402 away from the clamping block 9.

[0026] The correction block 1402 is attached to the surface of the material. The first pressure sensor 15 can collect the contact pressure data with the surface of the material in real time. After the clamping block 9 clamps the material, if the material has tilting, displacement or other posture deviations, the first pressure sensor 15 can detect the force.

[0027] An air pump 16 is fixedly installed on the side of the connecting plate 7 away from the clamping block 9. The air outlet of the air pump 16 is connected to a first central pipe 17. The first central pipe 17 is rotatably connected to the rotating shaft 8 through a bearing sleeve. An airflow channel 18 is opened inside the rotating shaft 8. The other end of the airflow channel 18 is connected to a first pipe 19.

[0028] The clamping block 9 has a placement groove 22 inside, and a cylinder 23 is installed inside the placement groove 22. The other end of the cylinder 23 is connected to a connecting rod 24. One end of the connecting rod 24 is fixedly connected to a top plate 25. A second pressure sensor 30 is installed at the bottom of the top plate 25.

[0029] The air pump 16 is electrically connected to the controller. After the sliding block 205 moves to the designated position, the controller starts the air pump 16. The high-pressure airflow generated by the air pump 16 is input to the airflow channel 18 of the clamping block 9 through the first central pipe 17. The airflow channel 18 diverts the high-pressure airflow to the first pipe 19, the second pipe 20 and the third pipe 21. The controller controls the cylinder 23 to start. The output end of the cylinder 23 generates a downward thrust that acts on the connecting rod 24, pushing the top plate 25 to move towards the material. The top plate 25 moves until it contacts the surface of the material and applies a clamping force to prevent the material from shifting in subsequent processing. The second pressure sensor 30 is used to detect the pressure contact data of the material being clamped.

[0030] A second pipe 20 is connected to the upper part of the first pipe 19. A first dust removal nozzle 26 is connected to one side of the second pipe 20. A third pipe 21 is connected to the lower part of the first pipe 19. A second dust removal nozzle 27 is connected to one side of the third pipe 21.

[0031] It should be noted that valves are installed on the outside of the first pipe 19, the second pipe 20, and the third pipe 21.

[0032] The second pipe 20 directs the airflow to the first dust removal nozzle 26, and the third pipe 21 directs the airflow to the second dust removal nozzle 27, thereby achieving simultaneous dust removal on the upper and lower surfaces and preventing impurities from affecting the clamping stability or subsequent detection accuracy.

[0033] A patch placement device 28 is installed above the operating table 1, and a vision inspection sensor 29 is fixedly installed on one side of the patch placement device 28.

[0034] The visual inspection sensor 29 can detect the front-side patching result and detect the cleanliness of the material surface. When the front side of the material is qualified, it can send a qualified signal to the controller. The controller can control the drive motor 10 to start and drive the material to rotate. After the rotation is completed, the visual inspection sensor 29 detects whether there is any material falling off during the flipping process, as well as the cleanliness of the back side of the material.

[0035] First, the controller adjusts the extension and retraction of the hydraulic cylinder 5 according to the material width, pushing the slider 4 to move laterally. Then, the conveying assembly 2 drives the sliding block 205 to move along the first guide rail 201 and the second guide rail 202, conveying the material to the designated workstation. The correction assembly 14 drives the correction block 1402 to correct the material posture through the differential extension and retraction of two sets of second electric push rods 1403. The first pressure sensor 15 synchronously feeds back the force to ensure accurate posture. Then, the air pump 16 is started. After the high-pressure airflow is split through the pipeline, it sprays dust onto the material surface through the first dust removal nozzle 26 and the second dust removal nozzle 27. Cleaning: The controller starts the cylinder 23, which pushes the top plate 25 to stably clamp the material. The vision inspection sensor 29 further detects the cleanliness of the material surface. After the cleaning is qualified, the patching equipment 28 is triggered to perform the front patching operation. At the same time, the patching result is detected. If the front patching and cleanliness are both qualified, the vision inspection sensor 29 sends a qualified signal to the controller. The controller starts the drive motor 10, which drives the material to rotate to the reverse side through belt transmission. After the rotation is completed, the vision inspection sensor 29 checks again whether the material has fallen off and the cleanliness of the reverse side. After confirming that there are no errors, the reverse patching or other subsequent processes can be performed.

[0036] The operating parameters are selected by the controller. The operating parameters include the initial pressure threshold P and the actual pressure threshold P1 set by the first pressure sensor 15, the amount of material after patching measured by the vision inspection sensor 29 as S and the actual measured amount of patching as S1, the standard amount of dust adhesion area C and the actual standard amount of area C1, the initial pressure threshold F and the actual pressure threshold F1 set by the second pressure sensor 30.

[0037] Example 1: The hydraulic cylinder 5 is controlled to extend and retract, pushing the slider 4 to move laterally along the slide groove 3, adjusting the distance between the two sets of symmetrically arranged clamping blocks 9 so as to match the size of the material. At the same time, the straightening block 1402 inside the clamping block 9 and the first pressure sensor 15 are in contact with the side of the material. If the actual value detected by the first pressure sensor 15 is P1>P at one end and P1<P at the other end, it means that the material is not in the center clamping position of the two sets of clamping blocks 9. At this time, the controller needs to first control the second electric push rod 1403 on the P1>P side to retract slightly, release the excessive pressure of the straightening block 1402 on the material on that side, and avoid the material deformation when pushing the material. Then, the controller controls the second electric push rod 1403 on the P1<P side to extend, driving the straightening block 1402 on that side to push towards the material, so that P1 on both sides is stably equal to the preset threshold P. Finally, the straightening block 1402 and the material are pushed to move synchronously until they are in a horizontal state. If the actual detected value of the first pressure sensor 15 shows that the pressure value P1 > P in some areas and the pressure value P1 < P in some areas, and the detected value is fluctuating, it can be determined that there are particulate impurities attached to the surface of the material, causing the actual detected value P1 to fluctuate. At this time, the air pump 16 is started and the valves at the second pipe 20 and the third pipe 21 are opened, so that the airflow can be output through the first dust removal nozzle 26 and the second dust removal nozzle 27 to clean the dust on the surface of the material.

[0038] If the actual measured value P1 equals P after dust removal, the judgment is correct. If P1 is still locally greater than P and locally less than P, the material itself is of substandard quality and needs to be replaced.

[0039] Example 2: When the actual detected value P1 of the first pressure sensor 15 is equal to P, it indicates that the material has not been displaced. Then, the controller controls the air pump 16 to start and opens the valves at the second pipe 20 and the third pipe 21, while closing the valve at the first pipe 19. This allows airflow to be output through the first dust removal nozzle 26 and the second dust removal nozzle 27, thereby cleaning the dust on the upper and lower surfaces of the material. After that, the valves at the second pipe 20 and the third pipe 21 can be closed, and the cylinder 23 is started. The output end of the cylinder 23 pushes the top plate 25 to stably clamp the material, and the extension distance of the output end of the cylinder 23 is fixed.

[0040] If the second pressure sensor 30 detects F1 < F, C1 > C, and S1 < S, it indicates that the thrust output by the cylinder 23 has not reached the preset value, resulting in insufficient tightness between the top plate 25 and the material surface. At this time, there is a small gap between the material and the top plate 25 and the clamping block 9, and they are not completely bonded. Furthermore, the dust cleanliness of the material surface is unqualified, and the number of materials mounted is low, with some missing. It can be determined that the sealing of the cylinder 23 has failed, resulting in insufficient material clamping stability. The unqualified cleanliness of the material surface leads to a reduction in the accuracy of the mounting process. At this time, the cylinder 23 can be repaired, and then the cylinder 23 can be re-supplied with air so that F1 reaches F. Finally, the controller controls the air pump 16 to start, generating a high-pressure airflow. The airflow can be output through the first dust removal nozzle 26 and the second dust removal nozzle 27, extending the dust removal time to twice the standard time. After the cleaning is qualified, a full-position mounting re-inspection is performed.

[0041] If the F1 detection data is still under-pressure after adjustment, check if the second pressure sensor 30 is worn. If the second pressure sensor 30 is faulty, it needs to be replaced.

[0042] If the second pressure sensor 30 detects that F1 equals F, C1 equals C, and S1 equals S, it indicates that the cleanliness of the front side of the material is qualified and the number of front-side patches is qualified. The drive motor 10 can then be started, causing its output to drive the belt drive assembly and the rotating shaft 8 to rotate, thereby flipping the material. After flipping, if C1 > C and S1 < S, it indicates that the patches were subjected to centrifugal force, friction, or collision force during the flipping process, causing some patches to fall off. Furthermore, during the flipping process, there are residual patch debris and dust from previous processes on the top of the operating table 1. The material makes slight contact with these areas during the flipping process, resulting in surface contamination. During the dyeing process, the reverse side process is paused. The controller controls the drive motor 10 to flip the material back to the front side. Only the first dust removal nozzle 26 is turned on to remove dust from the reverse side of the material. The cleanliness is detected by the visual inspection sensor 29 to ensure that C1 equals C. The material is then flipped back to the reverse side at low speed. After that, the visual inspection sensor 29 locates the position of the detached patch and controls the patching equipment 28 to perform precise patching. After patching, S1 is detected as S. The low-speed flipping is then started to complete the material flipping. After flipping, F1 is detected as F, C1 is detected as C, and S1 is detected as S. This indicates that the patching of the material on both sides is qualified and can proceed to the next step.
