[0014] In summary, this application includes the following beneficial technical effects:

[0015] 1. By mounting a transfer frame on the machine body surface, an electric push rod is installed on the inner wall of the transfer frame via a connecting frame. A robotic arm is mounted on one end of the electric push rod via an adjusting frame, facilitating the transfer of workpieces via the transfer frame.

A support frame is mounted on the surface of the transfer frame, with rotating wheels rotatably connected to its inner wall. The top of the rotating wheels is slidably connected to the bottom of the adjusting frame, providing support for the adjusting frame and reducing friction between the adjusting frame and the support frame, making the adjustment frame easier to move. A camera is connected to the top of the transfer frame via a mounting frame, with one end of the camera connected to one end of the electric push rod. This allows the camera to capture images of the upper part of the transfer frame and control the electric push rod to move the adjusting frame, facilitating adjustments to the robotic arm's position based on the workpiece size. This avoids the robotic arm and adjusting frame interfering with the use of the transfer frame. Compared to existing technologies, this significantly improves the efficiency of automatic loading and unloading of machine tools.

[0016] 2. A control motor can also be installed on the surface of the mounting frame. The output end of the control motor is connected to one end of the camera, so that the camera angle can be adjusted after the control motor is started, effectively increasing the camera's shooting range. A slide rail is slidably connected to the bottom of the mounting frame, and the bottom end of the slide rail is connected to the top of the transmission frame, so that the position of the mounting frame can be easily adjusted using the slide rail, making it easy to install the camera in a suitable position according to the size of the processed material. A threaded rod is threadedly connected to the inner wall of the mounting frame, and one end of the threaded rod is rotatably installed on the surface of the transmission frame, so that the moving position of the mounting frame can be adjusted and fixed using the threaded rod.

Figure 1 - Figure 2The system includes a CNC engraving and milling machine body 1. During use, the workpiece is placed inside the body 1 and fixed. A spindle box 2 is slidably installed on the inner wall of the body 1. The engraving and milling head at the bottom of the spindle box 2 rotates at high speed to engrave and mill the workpiece. A shielding door 3 is installed on the surface of the body 1 to shield the debris generated during the engraving and milling process. A transfer frame 4 is installed on the surface of the body 1. An electric push rod 7 is installed on the inner wall of the transfer frame 4 via a connecting frame 8. A robotic arm 6 is installed at one end of the electric push rod 7 via an adjusting frame 5. The workpiece is transferred using the transfer frame 4. The movement of the adjusting frame 5 is controlled by adjusting the length of the electric push rod 7, thereby increasing the movement range of the robotic arm 6. This effectively improves the automatic loading and unloading effect of the machine tool and avoids the problem of the transfer frame 4 being too large and affecting the use of the robotic arm 6.

[0024] Reference Figure 2 - Figure 4 A support frame 9 is mounted on the surface of the transmission frame 4. A rotating wheel 10 is rotatably connected to the inner wall of the support frame 9. The top of the rotating wheel 10 is slidably connected to the bottom of the adjustment frame 5. The support frame 9 supports the adjustment frame 5, and the rotating wheel 10 reduces the friction between the adjustment frame 5 and the support frame 9, making it easier for the adjustment frame 5 to move. A camera 12 is connected to the top of the transmission frame 4 via a mounting bracket 11. One end of the camera 12 is connected to one end of the electric push rod 7. The camera 12 captures the image of the upper part of the transmission frame 4 and controls the electric push rod 7 to move the adjustment frame 5. This allows for easy adjustment of the position of the robotic arm 6 according to the processing material, avoiding any impact on the use of the transmission frame 4 caused by the robotic arm 6 and the adjustment frame 5.

[0025] Reference Figure 2 - Figure 4 A control motor 13 is installed on the surface of the mounting frame 11. The output end of the control motor 13 is connected to one end of the camera 12. After the control motor 13 is started, the camera 12 is controlled to adjust its angle, effectively increasing the shooting range of the camera 12. A slide rail 14 is slidably connected to the bottom end of the mounting frame 11. The bottom end of the slide rail 14 is connected to the top of the transmission frame 4.

A support frame 9 is installed on the surface of the transmission frame 4, and a rotating wheel 10 is rotatably connected to the inner wall of the support frame 9. The top of the 10 is slidably connected to the bottom of the adjustment frame 5 so as to support the adjustment frame 5 with the support frame 9. The rotating wheel 10 reduces the friction between the adjustment frame 5 and the support frame 9, making the adjustment frame 5 easier to move. The top of the transmission frame 4 is connected to the camera 12 by the mounting frame 11. One end of the camera 12 is connected to one end of the electric push rod 7 so as to capture the image of the upper part of the transmission frame 4 with the camera 12 and control the electric push rod 7 to move the adjustment frame 5. This makes it easy to adjust the position of the robotic arm 6 according to the processing material and avoid the robotic arm 6 and the adjustment frame 5 from affecting the use of the transmission frame 4.

[0027] A control motor 13 can also be installed on the surface of the mounting frame 11. The output end of the control motor 13 is connected to one end of the camera 12, so that the camera 12 can be adjusted by controlling it after the control motor 13 is started, effectively increasing the shooting range of the camera 12. A slide rail 14 is slidably connected to the bottom end of the mounting frame 11. The bottom end of the slide rail 14 is connected to the top of the transmission frame 4, so that the position of the mounting frame 11 can be easily adjusted by the slide rail 14, and the camera 12 can be installed in a suitable position according to the size of the processed material.
