[0003] Among them, the automatic loading and unloading system plays an important role in automated production. Most of them are composed of industrial robots or gantry manipulators or suction cup devices. In the mechanical processing industry, the waste chips and residual coolant generated by machine tool processing often make the parts unable to be sucked by the suction cup, resulting in the interruption of automatic production and causing huge economic losses.

[0004] The current common treatment method is to add an air blow port on the workbench of the processing machine tool, which has the following problems: 1. Because it is necessary to consider that the air blow port cannot interfere with the tool and the Z-axis sheet metal of the machine tool during machine tool processing, the position of the air blow port cannot be adjusted at will; 2. Due to the limitation of the position of the air blow port, the air blow port cannot be adjusted to a suitable position, resulting in poor cleaning effect, and waste chips and residual coolant cannot be blown clean or cannot be blown away; 3. The cleaning efficiency is low, and it takes a relatively long time to blow to meet the cleaning requirements. Utility Model Content

The end of the gas-liquid nozzle seat connected to the gas-liquid nozzle is designed to be an inclined surface, so that the gas-liquid nozzle can have a larger pitch adjustment angle, and cooperate with the rotation of the gas-liquid nozzle seat itself to achieve a wider range of angle adjustment. The gas-liquid nozzle is more flexible to adjust and can adapt to workpieces of more shapes. When the suction cup device absorbs the parts, the waste chips and residual coolant generated by the machine tool processing can be quickly cleaned up. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The utility model has the following working principle:

[0031] When the workpiece needs to be transported to a processing machine, an industrial robot or a gantry manipulator controls the suction cup device to move above the workpiece to be processed. When the suction cup device passes over the workpiece to be processed, compressed air is sprayed out through the gas-liquid nozzle 05 on the suction cup device to clean the dust and foreign matter on the workpiece to be processed.

[0032] When the suction cup 07 contacts the workpiece to be processed, the vacuum generator is controlled to generate vacuum suction, so that the suction cup 07 adsorbs the workpiece to be processed.

[0033] The industrial robot or gantry manipulator controls the suction cup device to move the adsorbed workpiece to be processed and place it on the processing platform of the processing machine tool, controls the vacuum generator to disengage the suction cup 07 from the workpiece, and the industrial robot or gantry manipulator controls the suction cup device to move to the top of the next workpiece to be processed, repeats the above actions, adsorbs the workpiece to be processed, and waits for the workpiece to be processed by the processing machine tool.

[0034] When the workpiece is processed, the industrial robot or gantry manipulator controls the suction cup device to move above the workpiece processed by the machine tool. When the suction cup device passes above the processed workpiece, the coolant is sprayed through the suction cup device toward the front end (closer to the workpiece) of the main bracket 02 on one side of the processed workpiece to clean up the waste chips remaining on the processed workpiece. At the same time, compressed air is sprayed through the gas-liquid nozzle 05 at the rear end (farther away from the workpiece) of the suction cup device to clean up the coolant remaining on the processed workpiece (that is, the front end of the main bracket). Driven by an industrial robot or a gantry manipulator, the gas-liquid nozzle at the front end of the main bracket of the suction cup device of the utility model approaches the workpiece first, and the gas-liquid nozzle at the rear end approaches the workpiece later. In this way, the coolant is first sprayed out by the gas-liquid nozzle 05 at the front end to rinse the surface of the workpiece, and then the gas-liquid nozzle at the rear end can spray gas to blow away the coolant on the surface of the workpiece, making the cleaning of the workpiece faster and more efficient). The industrial robot or gantry manipulator controls the suction cup device to make the suction cup 07 come into contact with the processed workpiece, and controls the vacuum generator so that the suction cup 07 adsorbs the processed workpiece.

[0035] The industrial robot or the gantry manipulator controls the suction cup device to rotate, exchanges the positions of the unprocessed workpiece with the processed workpiece, and controls the vacuum generator to disengage the suction cup 07 from the workpiece to be processed.
