[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: a tool magazine for use with an optical grinding machine, including a grinding machine 1 and a tool magazine rack 2 disposed next to the grinding machine 1. The tool magazine rack 2 holds several different types of tools. A first drive module 3 is installed at the bottom of the tool magazine rack 2. A second drive module 4 is installed at the drive end of the first drive module 3. A robot 5 is installed at the drive end of the second drive module 4. A camera 6 is installed on the robotic arm of the robot 5. (It should be noted that the grinding machine 1, the tool magazine rack 2, the robot 5 and the camera 6 all adopt existing technology. The specific structure and principle will not be described in detail here.)
[0024] The first drive module 3 and the second drive module 4 have the same structure. The first drive module 3 includes a base 31 mounted on the upper part of the grinding machine 1. Linear guide rails 32 are symmetrically mounted on the upper part of the base 31. A movable seat 33 is slidably connected to the upper part of the linear guide rails 32. Connectors 34 are mounted on both sides of the movable seat 33. The reciprocating movement of the movable seat 33 is driven by a servo module.
[0025] The servo module includes a drive motor 35 installed inside the base 31, a belt drive assembly 36 rotatably connected to the end of the base 31, and lead screws 37 rotatably connected to both sides of the base 31. The driven end of the belt drive assembly 36 is connected to the driving end of the drive motor 35, and the driven end of the lead screw 37 is connected to the driving end of the belt drive assembly 36. The lead screw 37 and the connector 34 are connected by threads.
[0026] The belt drive assembly 36 includes a drive pulley, a driven pulley, and a synchronous belt. The drive pulley is connected to the drive end of the drive motor 35, and the driven pulley is installed at the end of the lead screw 37. The drive pulley and the driven pulley are connected by a synchronous belt drive.
[0027] When the first drive module 3 and the second drive module 4 are working, the drive motor 35 drives the belt drive assembly 36 to rotate, thereby driving the two lead screws 37 to rotate. Because the lead screws 37 and the connecting piece 34 are threadedly connected, when the lead screws 37 rotate, the movable seat 33 will move along the direction of the linear guide rail 32. Since the drive motor 35 is set as a servo motor, the drive end can rotate forward and reverse, so the movable seat 33 will also move back and forth.
[0028] When in use, the tool magazine can adjust the position of the robot 5 through the first drive module 3 and the second drive module 4, so that the robot 5 can move between the grinding machine 1 and the tool magazine holder 2. Specifically, the position of the robot 5 is detected by sensors, and the first drive module 3 and the second drive module 4 work in an orderly manner according to the detected position. This is existing known technology and will not be described in detail here.
[0029] When grinding machine 1 needs a tool change, the first drive module 3 and the second drive module 4 jointly drive robot 5 to the location of the tool on grinding machine 1. Then, camera 6 identifies the tool's position, and robot 5 removes the tool and returns to the tool magazine 2, placing it on the magazine. Then, it retrieves a new tool and installs it onto the spindle of grinding machine 1. The linkage between camera 6 and robot 5 works by using sensors such as industrial cameras, LiDAR, and structured light / ToF sensors to collect environmental images or point cloud data. Image preprocessing includes noise reduction, distortion correction, contrast enhancement, and feature extraction such as edge detection, corner detection, and contour extraction. Deep learning feature extraction techniques, such as convolutional neural networks (CNNs), are used for target recognition and pose estimation. The system constructs a spatial model through 3D reconstruction and pose estimation to achieve 3D object perception and localization. The decision-making and control module plans paths or adjusts actions based on image analysis results, enabling autonomous decision-making and control of the robot. This is a very mature technology in the current automation field, and the specific principles will not be detailed here.
