Description

Technical Field

[0001] This application relates to the field of robotics, and more particularly to a loading and unloading robot. Background Technology

[0002] Sheet metal stamping is a metal processing technique that primarily involves applying pressure to sheet metal to bend, shape, and cut parts of various shapes and sizes. Sheet metal stamping is widely used in the automotive, construction, electrical appliance, and furniture industries because this process can quickly and efficiently produce high-quality metal parts. In the sheet metal stamping process, the sheet metal is first fixed to a die, and then a stamping tool acts on the sheet metal, causing it to deform or cut.

[0003] Currently, many stamping production lines in China operate manually, and this manual operation does present several problems. Factors such as fatigue, operator skill, and experience limit the speed of operation, making it difficult to achieve high-speed, high-efficiency stamping. Errors during manual operation can lead to stamping failures and the creation of scrap. Furthermore, the operation carries inherent safety risks, as employees may become desensitized due to prolonged repetitive movements. In addition, this method makes it difficult to standardize and visualize the production process, hindering production management and optimization. Manual adjustment and adaptation to different models and specifications of sheet metal stamping equipment are also quite challenging.

[0004] Therefore, using loading and unloading robots for automated sheet metal stamping production lines is a better choice. Robots enable continuous and efficient stamping operations, reducing human error and safety risks, and improving product quality and production efficiency. Furthermore, integration with production management systems allows for visualization and controllability of the production process, facilitating production management and optimization. Moreover, robots can adapt to different models and specifications of sheet metal stamping equipment, meeting the needs of flexible production.

The rotary drive motor 18 installed on the rotary bearing 21 drives the rotary drive gear 22, thereby driving the rotary bearing 21 and realizing the overall rotation of the components installed at the bottom of the rotary bearing 21. Reference Appendix Figures 8 to 11In this embodiment, the end suction cup assembly 4 includes an end rotary table 23, an extension bracket 24, an end rotary drive motor 25, a fixing plate 26, a primary slider 27, two pressure plates 28, a double-speed synchronous belt 29, a primary linear guide rail 30, a shaft support seat 31, a double-speed synchronous belt pulley 32, a primary mounting plate 33, a secondary linear guide rail 34, a secondary slider 35, a secondary mounting bracket 36, an end rotating plate 37, a horizontal adjustment bar 38, a suction cup 39, a spring buffer 40, an extension drive motor 41, an extension motor mounting seat 42, an extension synchronous belt 43, an extension synchronous belt pulley 44, a lead screw 45, a nut seat 46, a bearing seat 47, a cylinder 48, a guide post 49, a linear bearing 50, a support shaft 51, a vertical adjustment bar 52, and a vision camera 54.The fixed plate 26 serves as the mounting base for the end suction cup assembly 4, mounted on the rotary support 21 within the end mounting bracket assembly 3. The primary mounting plate 33 is linearly connected to the fixed plate 26 via the primary linear guide 30 and the primary slider 27. The secondary mounting bracket 36 is linearly connected to the primary mounting plate 33 via the secondary linear guide 34 and the secondary slider 35. Shaft support seats 31 are mounted on both sides of the primary mounting plate 33 for mounting support shafts 51.

Between the secondary mounting brackets 36 on the same side, the displacement of the secondary mounting bracket 36 relative to the primary mounting plate 33 is achieved under the drive of the double-speed synchronous belt 29. Under the action of the synchronous belt, the linear displacement distances of the secondary mounting bracket 36, the primary mounting plate 33, and the fixed plate 26 are proportionally proportional. The extended drive motor 41 is mounted on the back of the secondary mounting bracket 36 through the extended motor mounting seat 42.

The lead screw 45 is installed between the bearing seats 47. The lead screw 45 is connected to the extended drive connection extended synchronous belt 43 through the extended synchronous pulley 44 installed at the end, realizing the power input. The nut seat 46 is threadedly mounted on the lead screw 45 and connected to the primary mounting plate 33. As the lead screw 45 rotates, the nut seat 46 moves back to its original position, causing the primary mounting plate 33 to move back to its original position, pulling the double-speed synchronous belt 29. The secondary mounting bracket 36 on the other side of the double-speed synchronous belt 29 also moves accordingly, achieving a linearly coupled motion relationship. The cylinder 48 is mounted on the front side of the secondary mounting bracket 36, with the end of the cylinder 48 connected to the extension bracket 24. Linear bearings 50 are mounted on both sides of the cylinder 48. Shaft supports 53 are mounted on both sides of the rear end of the extension bracket 24 to fix the guide post 49. The extension bracket 24 is connected to the linear bearings 50 through the guide post 49, achieving linear guidance of the extension bracket 24 relative to the secondary mounting bracket 36. The cylinder 48 pushes and the extension synchronous belt 43 drives the end suction cup assembly 4 to extend a long distance. The end rotary table 23 is mounted on the extension bracket 24. The rotary drive motor 18 is mounted on the end rotary table 23. The end rotating plate 37 is mounted on the end of the end rotary table 23. The rotary drive motor 18 realizes the rotation of the end. The horizontal adjustment bar 38 and the vertical adjustment bar 52 are mounted on the end rotating plate 37. The suction cup 39 is mounted on the vertical adjustment bar 52 and is used to pick up sheet metal materials. The suction range of the suction cup 39 is adjusted by adjusting the position between the horizontal adjustment bar 38 and the vertical adjustment bar. The vision camera is mounted at the front end of the extension bracket. Through the vision recognition of the vision camera, the loading and unloading robot realizes stable gripping of sheet metal materials on the conveyor belt.

[0024] The present invention uses a synchronous pulley pair consisting of a double-speed synchronous belt 29 and a double-speed synchronous pulley 32 in the end suction cup assembly 4 to install the synchronous pulley pair on the first-stage mounting plate 33. The upper side of the double-speed synchronous belt 29 is connected to the fixing plate 26, and the lower side is connected to the second-stage mounting bracket 36. This achieves a proportional relationship between the displacement distance of the first-stage mounting plate 33 and the displacement distance of the second-stage mounting bracket 36 while the fixing plate 26 remains stationary. Through the drive of the cylinder 48 and the linear guidance of the guide posts 49 on both sides, the long-distance displacement of the protruding bracket 24 is achieved. The device is connected to the end rotary plate via the end rotary table 23 mounted on the extension bracket 24. The rotation of the end rotary plate is achieved by the end rotary drive motor 25 mounted on the end rotary table 23, which facilitates coordinate position control in the program. Example 2

[0025] This application also discloses an embodiment of a sheet metal stamping production line, which includes a punch press and the aforementioned loading and unloading robots are installed on the punch press to achieve automated and efficient sheet metal stamping operations.

[0026] For specific usage, please refer to the attached document. Figure 12 ; The sheet metal stamping line has multiple punch presses (the rest are not shown) and a conveyor belt. The punch presses are arranged linearly and laterally, and the conveyor belt is arranged along the working opening of the punch presses. Operators only need to load sheet metal at the starting point of the production line. The conveyor belt automatically delivers the sheet metal to the designated gripping position. The loading and unloading robot in front of the punch press, driven by the vertical drive motor 13 and the horizontal drive motor 17, moves the end suction cup assembly 4 to the vision recognition position. After the vision camera 54 recognizes the sheet metal position, it moves the end suction cup 39 to the sheet metal gripping position through the vertical drive motor 13, the horizontal drive motor 17, and the end rotation drive motor 25. After the sheet metal is picked up by the suction cup 39, it is moved to a higher position and turned around under the drive of the rotation drive motor 18, delivering the sheet metal to the position pointing towards the punch press. The extension drive motor 41, through the extension timing pulley 44 and the extension... The synchronous belt 43 drives the lead screw 45 to rotate, the nut seat 46 moves and drives the first-stage mounting plate 33 to move, the pressure plate 28 drives the double-speed synchronous belt 29 to move, and the pressure plate 28 on the other side drives the second-stage mounting bracket 36 to move, realizing the stroke doubling displacement action. At the same time, the cylinder 48 pushes and extends under the guidance of the guide column 49 to realize the long-distance extension action, sending the sheet metal to the punching position. Then the loading and unloading robot exits to perform the stamping work. After the stamping work is completed, the loading and unloading robot grabs and takes it out and places it on the other side of the conveyor belt for the next stamping process. The subsequent loading and unloading robots are the same, with a total of five processes. After completion, the operator takes the sheet metal off the conveyor belt.

Therefore, the disclosed embodiments described above are merely illustrative in all respects and are not the only ones. All modifications within the scope of this application or equivalent to this application are included in this application.
