[0012] The automatic blowing device after cleaning of parts of the present invention has the following working principles: when parts arrive, the parts touch plate 1 is touched, and the parts arrival signal is transmitted to the PLC control system through the trigger mechanism rotating shaft 3 and the signal trigger plate 4, so as to start the automatic blowing program; four magnetic switches detect the position of the cylinder piston and transmit the signal to the PLC control system, so as to control the interval swing position of the air curtain and calculate the number of swings, and control the start and stop of the blow operation of the driven air pipe; the intermediate relay converts the control signal sent by the PLC into a signal for the action of the larger current air valve; The cylinder 12 drives the hinge 14 to control the master and slave air pipe welding assembly 6 to make a 90-degree rotational movement through telescoping; the hinge 8 connects the master and slave air pipe welding assembly 6 for rotational movement, driving the master and slave air pipe welding assembly 6 to make a 90-degree rotational movement; the four air pipe assemblies, namely the left and right active air pipe assemblies and the left and right slave air pipe assemblies, are respectively equipped with five direction-adjustable spherical clamp nozzles 7 in the upper and lower directions, and the high-pressure wind is blown to the water storage area of ​​the parts by adjusting the direction of the spherical clamp nozzles 7; four magnetic switches are installed on the control cylinder 12 to detect the cylinder piston position and return it to the electrical control system, dividing the cylinder movement into three areas, and according to the blowing control program, in each blowing operation cycle, the air pipe assembly is swung back and forth 2 to 3 times in the three areas, so that the 90-degree rotation angle of the pneumatic pipe assembly is divided into three areas, and it swings continuously in each area to form a swinging state of the wind curtain, causing disturbances in low-lying water storage areas, accelerating the blowing speed, and improving the blowing effect. The two air pipe outlets of the left and right active air pipe assemblies form a symmetrical shooting state, and the initial position of the nozzle faces the right end, that is, the direction of the parts, extending the blowing range to the right by 500mm. When the control system issues a blowing command, the left and right active air pipes operate in front of the parts. As the parts move forward, the active air pipes change their angles and swing under the drive of the cylinder 12, so that the position where the air curtain acts on the parts gradually moves backward, forming a 360-degree operation without dead angles; the two air pipe outlets of the left and right driven air pipe assemblies form a symmetrical shooting state, and the initial position of the nozzle faces the left end, that is, the direction of the parts. , extend the blowing range to the left by 500mm. When the left and right active air pipes are working, they move toward the parts under the action of the hinge 14. When the parts enter the middle position of the master and slave air pipes, that is, within the operating range of the left and right slave air pipes, the slave air pipe nozzle starts blowing and the active air pipe nozzle stops working. At this time, the control cylinder 12 reaches the terminal and reverses to return to the initial position, so that the position where the slave air pipe wind curtain acts on the parts gradually moves backward, forming a 360-degree no-dead-angle operation again. When the control cylinder reaches the initial position, the slave air pipe blowing operation is stopped, waiting for the next part to arrive.

[0013] The automatic blowing device for cleaning parts of the present invention can automatically reduce the number of swings when the parts are small and the spacing between them is small, and when the interval time for executing the standard program is insufficient, and operate as the parts move, thereby ensuring that no parts are missed and the blowing effect is guaranteed; the master and slave air pipe devices are switched on and off alternately according to the positions of the parts, thereby saving air sources.

[0014] The automatic blowing device for cleaning parts of the present invention adopts automatic touching, signal transmission, automatic air on and off, and automatic control mechanism of parts; compared with the traditional air curtain method of blowing, the number of air curtains can be reduced, space can be saved, investment costs can be reduced, existing hidden dangers can be eliminated, labor intensity can be reduced, and it is safer and more reliable, so that the process can be automated and unmanned, and comprehensive and multi-directional blowing of various parts of all products can be achieved, the potential hidden dangers of inadequate blowing and missed blowing can be avoided, the adverse effects of external factors can be completely eliminated, and a qualitative change from nothing to something can be achieved.
