[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0026] In the prior art, neither separating devices using a beveled tooth structure nor separating devices using magnetic materials can effectively separate and accurately feed the sheets. Therefore, to address the aforementioned technical issues, the present application provides a separating device that, by combining machine vision, automatic height measurement, and airflow separation, achieves single-sheet separation and precise feeding of the sheets. This significantly improves the automation level and accuracy of aluminum bright trim separation and feeding, reduces equipment failures and downtime, and improves overall production efficiency and product quality.

[0027] This application uses the application scenario of separating single sheets of aluminum bright trim strips as an example to introduce the structure and usage of the sheet separation device in this application. The sheet separation device provided in this application is not only suitable for separating sheets of aluminum bright trim strips, but can also adapt to the requirements of separating sheets of other similar non-magnetic materials, and has high versatility. Specifically:

[0028] A sheet separation device includes a bracket 1 and a suction cup 2, an air nozzle 3, and a distance measuring assembly 4 disposed on a first side of the bracket 1. The suction cup 2 forms a suction surface for adsorbing a sheet. The air nozzle 3 is disposed at the edge of the suction surface and at a lower level than the suction surface. The spacing between the air nozzle 3 and the suction surface is adjustable. The distance measuring assembly has a distance measuring end disposed at the edge and upper surface of the suction surface for measuring the thickness of a single sheet. By disposing the distance measuring end of the distance measuring assembly at the edge and upper surface of the suction surface, the height of a single sheet is determined based on the height difference between the edge and the upper surface. The height of the air nozzle 3 is then adjusted based on the height of the single sheet, allowing the air nozzle 3 to accurately blow a high-pressure airflow into the junction of two sheets, separating the sheets and thus achieving precise feeding.

[0029] In some embodiments, the distance measuring assembly 4 includes a first height sensor 41 and a second height sensor 42. The distance measuring end of the first height sensor 41 is disposed within the adsorption surface and is configured to abut the web; the distance measuring end of the second height sensor 42 is disposed at the edge of the adsorption surface. Specifically, the height of the web's upper surface can be measured by the first height sensor 41, and the height of its lower surface can be measured by the second height sensor 42. The web's height can then be determined based on the height difference between the first and second height sensors 41, 42. The height of the air nozzle 3 can then be adjusted based on the web's height, allowing the air nozzle 3 to accurately deliver the high-pressure airflow into the junction of the two webs.

[0030] In some embodiments, the device includes at least two suction cups 2 and at least two air nozzles 3. All suction cups 2 are arranged at the same height and together form a suction surface. All air nozzles 3 are sequentially arranged along the edge of the suction surface. Providing multiple suction cups 2 to form a suction surface improves the gripping effect on the web. Simultaneously, multiple air nozzles 3 can blow air from various directions, separating the web held by the suction cups 2 from other webs, thereby achieving web separation.

[0031] In some embodiments, each suction cup 2 is equipped with an air nozzle 3, which is located on the side of the suction cup 2 close to the suction surface. By providing a one-to-one correspondence between the suction cup 2 and the air nozzle 3, the suction cup 2 and the air nozzle 3 can be installed on the same mounting member, simplifying installation.

[0032] In some embodiments, the horizontal distance between the air nozzle 3 and the suction cup 2 is adjustable. Specifically, by adjusting the distance between the air nozzle 3 and the suction cup 2 according to the size of the web, the air nozzle 3 can be aligned with the edge of the web of different sizes, thereby meeting the requirements for separating webs of different sizes.

[0033] In some embodiments, a fixing member 5 is further included; the suction cup 2 is connected to the bracket 1 via the fixing member 5; the fixing member 5 is provided with a limiting groove 6, and the air nozzle 3 is movably disposed in the limiting groove 6. This allows the air nozzle 3 to slide in the limiting groove 6 according to the size of the sheet, thereby accommodating sheets of different sizes and effectively separating sheets of different sizes.

[0034] In some embodiments, a manipulator 8 is further included, wherein a control end of the manipulator 8 is connected to the second side of the bracket 1. The manipulator 8 can control the bracket 1 to move, thereby realizing the operation of moving the sheet.

[0035] In some embodiments, a quick-change tray 7 is provided on the second side of the bracket 1; the quick-change tray 7 is detachably connected to the bracket 1; and the end of the quick-change tray 7 away from the bracket 1 is connected to the control end of the robot 8. By connecting the robot 8 to the bracket 1 via the quick-change tray 7, when different sheet products need to be separated, the quick-change tray 7 can be replaced to meet the needs of multi-product production.

[0036] In some embodiments, a positioning assembly 9 is further provided on the first side of the bracket 1; the positioning end of the positioning assembly 9 faces the suction surface to obtain the position information of the web; the positioning assembly 9 is in communication with the robot 8, and based on the position information, the positioning assembly 9 instructs the robot 8 to move the bracket 1 to a specified position. By providing the positioning assembly 9 on the bracket 1, the positioning assembly 9 can be used to obtain the web's position information and instruct the robot 8 to automatically move the bracket 1 to the specified position, enabling the robot 8 to automatically identify the web's location and complete the automatic movement operation.

[0037] In some embodiments, the positioning assembly 9 includes a camera 91 and a distance sensor 92; the camera 91 is disposed on a first side of the bracket 1, with the lens of the camera 91 facing the adsorption surface; the distance sensor 92 is disposed on a first side of the bracket 1, with the distance end of the distance sensor 92 facing the adsorption surface. The camera 91 can capture an image of the sheet and determine the sheet's position based on the image; and the distance sensor 92 can capture the height difference between the sheet and the sheet. That is, the image recognition and distance sensor 92 can determine the sheet's position and height. Path planning and obstacle avoidance algorithms are combined to ensure that the robot arm 8 can safely move to the sheet's position. The intelligent gripper's feedback force is used to control the sheet's grasp and transport it to the mold area. Finally, the placement is confirmed to be complete, achieving the purpose of accurately grasping and releasing the sheet.
