[0046] Reference Figures 1 to 6 , a fully automatic sandblasting device, comprising a feeding device 100, a material moving device 200 and a plurality of sandblasting machine bodies 300;

[0047] The feeding device 100 is used to transport the roller to be sandblasted and the roller that has been sandblasted;

[0048] The sandblasting machine body 300 is arranged on the peripheral side of the feeding device 100, and a roller driving device 400 for clamping and driving the roller to rotate is arranged on the sandblasting machine body 300;

[0049] The material transfer device 200 is disposed between the material feeding device 100 and the sandblasting machine body 300, and is used to transfer the roller from the material feeding device 100 to the roller driving device 400 or to transfer the roller from the roller driving device 400 to the material feeding device 100;

[0050] The sandblasting machine body 300 is used to sandblast the workpiece placed in the drum on the drum driving device 400 .

[0051] ① In the present invention, the material moving device 200 is preferably a manipulator, and the controller is connected to the feeding device 100, the material moving device 200 and a plurality of sandblasting machine bodies 300, and performs corresponding control according to the feedback of each sensor data; specifically, when the fully automatic sandblasting machine system is working, the manipulator is first used to transfer the rollers 800 to be sandblasted on the loading station of the first conveyor frame 110 to the roller driving device 400 in the sandblasting machine body 300 one by one for sandblasting. After the sandblasting is completed, the manipulator takes the sandblasted roller 800 out of the sandblasting machine body 300 and places it on the unloading station of the second conveyor frame 120, re-grasps the roller 800 to be sandblasted on the loading station of the first conveyor frame 110 and places it in the roller driving device 400 in the sandblasting machine body 300, and repeats the cycle.

[0052] ② In the feeding device 100, the feeding device 100 includes a first conveying frame 110, a second conveying frame 120, a first conveying device 130, a second conveying device 140, a plurality of first detection devices 150 and a plurality of second detection devices 160; a plurality of loading stations are arranged on the first conveying frame 110 along its loading direction A; the second conveying frame 120 is arranged below the first conveying frame 110 and a plurality of unloading stations are arranged along its unloading direction B; the first conveying device 130 is arranged on the first conveying frame 110, and is used to convey the rollers 800 to be sandblasted to pass through the loading stations in sequence; the second conveying device 140 is arranged on the second conveying frame 120, and is used to convey the rollers 800 that have been sandblasted to pass through the unloading stations in sequence; the first detection device 150 is arranged at the loading station, and is used to detect whether there are rollers 800 to be sandblasted at the loading station; the second detection device 160 is arranged at the unloading station, and is used to detect whether there are rollers 800 that have been sandblasted at the unloading station.

[0053] Specifically, take the first conveyor frame 110 with three loading stations as an example: the worker first places the first roller 800 to be sandblasted on the first conveyor frame 110 one by one along the loading direction A. When the first detection device 150 on the first loading station detects that there is a roller 800 to be sandblasted on the first loading station, it sends a command to the controller, and the controller controls the first conveying device 30 to drive the roller 800 to be sandblasted to move to the second loading station; the worker then places the second roller 800 to be sandblasted on the first loading station. When the first detection device 150 on the first loading station detects again that there is a roller 800 to be sandblasted and there is also a roller 800 to be sandblasted on the second loading station, it sends a command to the controller, and the controller controls the first conveying device 30 to drive the first roller 800 to be sandblasted to move to the third loading station and drive the second roller 800 to be sandblasted to move to the third loading station. The second loading station moves; the worker then places the third roller 800 to be sandblasted on the first loading station. When the first detection devices 150 on the first loading station, the second loading station and the third loading station all detect the existence of the roller 800 to be sandblasted, a command is sent to the controller. The controller first controls the lifting device 60 to lift the first roller 800 to be sandblasted on the third loading station to separate from the first conveying device 30, and then controls the first conveying device 30 to drive the second roller 800 to be sandblasted to move toward the third loading station and drive the third roller 800 to move toward the second loading station, and finally controls the lifting device 500 to drop the first roller 800 to be sandblasted on the third loading station back to the third loading station, so as to avoid the first roller 800 to be sandblasted from rubbing against the first conveying device 130 at the third loading station.

[0054] Furthermore, the sandblasted drum 800 is placed on the second conveyor rack 120 under the grip of the robot. When the second detection device 160 detects the presence of the sandblasted drum 800 on the first unloading station, it sends an instruction to the controller, and the controller controls the second conveying device 140 to convey the sandblasted drum along the unloading direction B.

[0055] ③ In the roller driving device 400, the roller driving device 400 includes a base 410, a placement rack 420, a driving device 430, a third detection device 440 and a fourth detection device 450; a rotating shaft 460 is arranged on the base 410, and an axially penetrating detection groove 461 is arranged in the rotating shaft 460; the placement rack 420 is connected to the front end of the rotating shaft 460 for placing the roller; the driving device 430 is arranged on the base 410 and connected to the rotating shaft 460, and is used to drive the rotating shaft 460 to rotate; the third detection device 440 is arranged in the detection groove 461, and is used to detect whether there is a roller on the placement rack 420; the fourth detection device 450 is arranged on the base 410, and is used to detect the angle of the rotating shaft 460.

[0056] Specifically, the roller driving device 400 is installed in the sandblasting machine body 300, and the roller 800 in the feeding device 100 is transferred to the roller driving device 400 in the sandblasting machine body 300 by the manipulator. Specifically, the roller 800 is placed on the placement rack 420. Since the placement rack 420 is provided with a detection hole arranged opposite to the third detection device 440, the third detection device 440 can detect whether there is a roller 800 on the placement rack 420 through the detection hole; secondly, when the manipulator exits the sandblasting machine body 300, the driving device 430 is started to drive the rotating shaft 460 on the machine base 410 to rotate. , so that the rotating shaft 460 drives the third detection device 440 to rotate together, and the sandblasting gun is started to sandblast the workpiece in the drum 800; when the sandblasting is completed, the driving device 430 continues to operate until the second photoelectric sensor 452 detects the trigger sheet 451, thereby judging the angle of the rotating shaft 460 (the placement rack 420), and then feeding back to the controller, it can provide the manipulator with an accurate grasping position (avoiding the side ears on the drum 800). After the manipulator takes out the sandblasted drum 800 from the sandblasting machine body 300, it re-grasps another drum 800 to be sandblasted and places it in the drum driving device 400, and the cycle continues.

[0057] ④ The sandblasting machine system may preferably include 1 set of material moving devices 200, 3 sets of feeding devices 100 and 3 sets of sandblasting machine bodies 300.
