[0102] Working principle and usage:

[0103] The first step is pre-setting:

[0104] Press the start switch to debug the power supply of the device.

[0105] Adjust the control program according to the position of the workpiece hanging hole. Select the appropriate "J" shaped hook 407.

[0106] Step 2: Prepare the ingredients:

[0107] Press the material preparation switch, and the PLC controller starts electromagnet one and electromagnet three.

[0108] Electromagnet three attracts the "J" shaped hook 407.

[0109] The operator inserts the workpieces to be processed into the fixed frame 205 in order. The electromagnet 1 absorbs the lower end of the workpiece so that the hanging holes (or hanging rings) of the workpieces in the fixed frame 205 are all located at the same height, completing the material preparation.

[0110] Step 3: Loading:

[0111] Press the loading switch, and the PLC controller outputs signals to the electric lifting device 201, the screw stepping motor 202, the electromagnet 1, the electric lifting device 204, the electric lifting device 301, the push rod motor 302, the electromagnet 2, and the stepping motor 304.

[0112] The electric lifting device 201 drives the movable loading box to move up a certain distance, so that the workpiece hanging hole and the "J"-shaped hook 407 are at the same height.

[0113] The push rod motor 302 drives the electromagnet 2 to approach the workpiece, and the distance sensor module 1 outputs a signal to the PLC controller; the PLC controller outputs a signal to the electromagnet 2, the electric lifting device 204, the screw stepper motor 202, the push rod motor 1 302, the electric lifting device 301, and the stepper motor 1 304.

[0114] The second electromagnet is activated to absorb the workpiece, the first electromagnet is closed after a delay, and the second electric lifting device 204 drives the fixed frame 205 to move downward; the movable end of the first electric lifting device 201 moves downward after a delay, so that the fixed frame 205 is separated from the workpiece.

[0115] The screw stepper motor 202 drives the fixing mechanism to move to a side away from the push rod motor 302. The push rod motor 302 delays the transport of the workpiece to the "J"-shaped hook 407. The movable end of the push rod motor 302 is reset.

[0116] The electromagnet 2 is closed with a time delay, and the electric lifting device 301 drives the push rod motor 1 302 to move downward, thereby reducing the displacement of the "J"-shaped hook 407 when the movable end of the push rod motor 1 302 is reset.

[0117] The stepper motor 1 304 drives the fixed cylinder 306 to rotate a preset angle (the rotation angle is determined by the distance sensor module 3 auxiliary PLC controller), so that the unloaded "J"-shaped hook 407 is aligned with the movable end of the push rod motor 1 302.

[0118] Afterwards, repeat the above process of this step.

[0119] The third step is to transport materials:

[0120] When the material transport switch is pressed, the PLC controller outputs signals to the screw stepper motor 2 401, the electric lifting device 403, the stepper motor 2 404 and the electromagnet 3.

[0121] The electric lifting device four 403 drives the active end of the stepping motor two 404 to move down a certain distance, and the stepping motor two 404 drives the "cross" shaped positioning column to rotate until it is aligned with the "cross" shaped through groove; the distance sensor module two outputs a signal to the PLC controller, and the PLC controller controls the electric lifting device four 403 to move down, so that the "cross" shaped positioning column and the "cross" shaped through groove overlap, and the electromagnet three is started to complete the docking of the two.

[0122] The electric lifting device 403 drives the stepping motor 2 404 to reset.

[0123] The screw stepper motor 2 401 drives the mounting mechanism to move into the sandblasting seat 104, and the distance sensor module 4 outputs a signal to the PLC controller; the PLC controller outputs a signal to the sandblasting device, the push rod motor 2 501, and the electromagnet 4.

[0124] The push rod motor 501 drives the movable gate 502 to seal the rectangular through hole 2.

[0125] Electromagnet four starts.

[0126] The sandblasting device is started, and the stepper motor 2 404 drives the movable carrier plate 5 406 to rotate a fixed angle at a fixed time to complete the sandblasting process of the entire workpiece.

[0127] Embodiment 2, based on embodiment 1, a clamping claw motor is added to the "cross" shaped positioning column to further improve stability.
