[0037] The working principle and use process of the utility model are as follows: first, the left Z-axis base plate 4 is fixedly installed on the Z-axis drive system, and then the vacuum nozzle 9 material picking and unloading coordinates and the rotating nozzle 25 material swinging coordinates are set on the upper computer. After that, the Z-axis drive system works to make the left Z-axis base plate 4 slide to make the vacuum nozzle 9 reach the material picking position, and then the left material feeding clamp driven plate 16 is started to rotate to drive the driving wheel 21 to rotate, so that the main synchronous belt 2 is used to drive the idler wheel 1 to rotate. Because the first reverse buckle synchronous belt 27 and the second reverse buckle synchronous belt 30 are meshed with the main synchronous belt 2, the synchronous belt driving plate 26 and the synchronous belt pressing plate 29 are driven to slide, so that the first The sliding block 20 moves downward to drive the material picking bracket fixing block 8 to move downward, and the second sliding block 22 moves upward to drive the left material clamp driven plate 16 and the swing material bracket fixing block 13 to move upward. After approaching the device, the material picking air pipe joint 23 is opened to generate suction at the vacuum suction nozzle 9 to suck up the device, and then the second stepper motor 19 is started to make the main synchronous belt 2 rotate in the opposite direction. At this time, the material picking bracket fixing block 8 rises and the swing material bracket fixing block 13 slides downward to make the device move upward to the movement height. After that, the left Z-axis bottom plate 4 moves to the material discharge coordinate again, and the vacuum suction nozzle 9 is lowered by the above steps, and the material picking air pipe joint 23 is closed, so as to realize material discharge;
[0038] After the material discharge is completed, the vacuum suction nozzle 9 rises, and the left Z-axis bottom plate 4 moves so that the rotary suction nozzle 25 moves to the material picking coordinate, and then the second stepper motor 19 is started to rotate 90 degrees clockwise to rotate the swing material bracket fixing block 13 to drive the rotary suction cup bracket 15 to be vertical, and then repeat the above operation to move the rotary suction nozzle 25 downward to the material picking position, and then open the swing material air pipe joint 14 to make the rotary suction nozzle 25 generate suction to suck the device, and then the rotary suction nozzle 25 moves upward to the operating height, and the first stepper motor 18 rotates counterclockwise to make the rotary suction nozzle 25 drive the device to perform indexing motion and rotate 90 degrees, and then the left Z-axis bottom plate 4 moves to the swing material coordinate, and then repeat the above operation to put the device down to complete the swing material action;
[0039] At the same time, during the material picking and swinging process, the first photoelectric switch 5, the second photoelectric switch 6, the left upper material Z-axis light block 7, the left upper material detection light block 28 and the third photoelectric switch 11, the fourth photoelectric switch 12 and the left Z-axis rotation light block 24 are used to ensure the accuracy of the material picking and swinging positions, so as to realize the integrated structure of material picking and swinging.
[0040] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
