The system alarm will be automatically cancelled and will continue to run automatically.

[0037] 2. Automatic loading and unloading and long-face fine grinding process: When the first rough-ground lightweight refractory brick blank 4 placed on the four clamping positions of the pneumatic clamping turntable 115 of the long-face rough grinding brick machine 19 rotates to the loading and unloading position, the sensor will automatically feed back a signal to the control system. Under the precise control of the control system, the servo motor 113, RV reducer 114 and pneumatic clamping turntable 115 stop rotating. Then the control system controls the solenoid valve to drive the long-face pneumatic clamping cylinder 302 to move, which in turn pushes the long-face pneumatic clamping moving clamping plate to move backward, releasing the clamping plate and releasing the rough-ground lightweight refractory brick blank on the clamping position. Then the control system controls the narrow-face loading and unloading robot 2 8 and the narrow-face loading and unloading robot 1 7 to move, and at the same time starts the narrow-face pneumatic gripper 6 and the long-face fine grinding brick machine 18.

Under the precise control of the control system, the servo motor 113, RV reducer 114 and pneumatic clamping turntable 115 stop rotating. Then the control system controls the solenoid valve to drive the long-face pneumatic clamping cylinder 302 to move, which in turn pushes the long-face pneumatic clamping moving clamping plate to move backward, releasing the clamping plate and releasing the finely ground lightweight refractory brick on the clamping position. Then the control system controls the wide-face loading and unloading robot 11 and the narrow-face loading and unloading robot 28 to move, and at the same time starts the narrow-face pneumatic gripper 6, the wide-face pneumatic gripper 10 and the narrow-face grinding brick machine 17.

Then, the control system controls the servo motor 113, RV reducer 114, pneumatic clamping turntable 115 and grinding head drive motor 110 to drive the grinding head to start rotating and processing, and so on, to perform narrow-face grinding processing on the semi-finished lightweight refractory bricks.

Then, the control system controls the servo motor 113, RV reducer 114, pneumatic clamping turntable 115 and grinding head drive motor 110 to drive the grinding head to start rotating and processing. This cycle is repeated to perform fine grinding processing on the long surface of the lightweight refractory brick blank 4.

[0041] 4. Automatic loading and unloading and wide-face grinding process: When the first polished lightweight refractory brick semi-finished product placed on the four clamping positions of the pneumatic clamping turntable 115 of the narrow-face brick grinding machine 17 rotates to the loading and unloading position, the sensor will automatically feed back a signal to the control system.

Then the control system controls the solenoid valve to drive the narrow-face pneumatic clamping cylinder 202 to move with the narrow-face pneumatic clamping guide rod 203, which in turn pushes the narrow-face pneumatic clamping moving clamping plate to move backward, releasing the clamping plate and releasing the polished lightweight refractory brick semi-finished product from the clamping position. Then the control system controls the movement of the wide-face loading and unloading robot 2 12 and the wide-face loading and unloading robot 1 11, and simultaneously starts the wide-face pneumatic gripper 10 and the wide-face brick grinding machine 16. The wide-face loading and unloading robot 12 adjusts its posture to pick up the semi-finished lightweight refractory bricks ground on the narrow-face brick grinding machine 17 and place them into the clamping position of the pneumatic clamping turntable 115 of the wide-face brick grinding machine 16. Then, the control system controls the solenoid valve to drive the wide-face pneumatic clamping cylinder 104 to move the wide-face pneumatic clamping guide rod 105, which in turn pushes the narrow-face pneumatic clamping moving clamping plate forward, working together with the wide-face pneumatic clamping fixing clamping plate 108 to clamp the semi-finished lightweight refractory bricks in the clamping position. Then, the control system controls the servo motor 113, RV reducer 114, pneumatic clamping turntable 115 and grinding head drive motor 110 to drive the grinding head to start rotating and processing, and so on, to perform wide-face grinding processing on the semi-finished lightweight refractory bricks.

[0042] The wide-face loading and unloading robot 11 picks up the lightweight refractory brick semi-finished product, which has been finely ground by the long-face fine grinding brick machine 18, and places it into the clamping position of the pneumatic clamping turntable 115 of the narrow-face brick grinding machine 17. Then, it controls the solenoid valve to clamp the lightweight refractory brick semi-finished product in the clamping position. Then, the control system controls the servo motor 113, RV reducer 114, pneumatic clamping turntable 115, and grinding head drive motor 110 to drive the grinding head to start rotating and processing. This cycle is repeated to grind the narrow face of the lightweight refractory brick semi-finished product.

[0043] 5. Finished product unloading and automatic stacking process after grinding: When the first ground lightweight refractory brick semi-finished product placed on the four clamping positions of the pneumatic clamp turntable 115 of the wide-face brick grinding machine 16 rotates to the unloading position, the sensor will automatically send a feedback signal to the control system. Under the precise control of the control system, the servo motor 113, RV reducer 114 and pneumatic clamp turntable 115 stop rotating. Then the control system controls the solenoid valve to drive the wide-face pneumatic clamp cylinder 104 to move with the wide-face pneumatic clamp guide rod 105, which in turn pushes the wide-face pneumatic clamp moving clamp plate to move backward, releasing the clamp plate and releasing the ground lightweight refractory brick semi-finished product on the clamping position. Then the control system controls the long-face unloading robot 14 and the wide-face unloading robot 12 to move, and at the same time starts the wide-face pneumatic gripper 10 and the long-face pneumatic gripper 13. The long-face loading and unloading robot 14 adjusts its posture to pick up the finished lightweight refractory bricks 15, which have been ground on the wide-face brick grinding machine 16, and places them on the pallet 3 at the unloading position for automatic stacking. This cycle continues until a set number of layers are stacked, at which point the system automatically alarms, prompting the worker to transfer the stacked pallet away and replace it with an empty pallet. The alarm is automatically canceled after the system confirms the replacement of the empty pallet, and the automatic operation continues. The wide-face loading and unloading robot 12 picks up the semi-finished lightweight refractory bricks ground by the narrow-face brick grinding machine 17 and places them into the clamping position of the pneumatic clamping turntable 115 of the wide-face brick grinding machine 16. Then, it controls the solenoid valve to clamp the semi-finished lightweight refractory bricks in the clamping position. The control system then controls the servo motor 113, RV reducer 114, pneumatic clamping turntable 115, and grinding head drive motor 110 to rotate the grinding head for processing. This cycle repeats to perform wide-face grinding processing on the semi-finished lightweight refractory bricks.

[0044] This invention generates a large amount of dust during the grinding process. At this time, the dustproof rubber sheet 111 and the dust cover 112 of the grinding head on each brick grinding machine come into play. The dustproof rubber sheet 111 and the dust cover 112 of the grinding head form a closed environment. The dust cover 112 of the grinding head is connected to a large vacuum cleaner outside. In the closed environment, the dust is sucked away to the maximum extent. Large particles will automatically fall into the box 102. The box door 101 can be opened periodically for cleaning, thereby effectively preventing excessive dust in the workshop, greatly reducing environmental pollution, and improving the working environment.
