[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses an automatic cleaning mechanism for electronic circuit board mounting heads, comprising a housing 1 and an adjusting frame 5. One side of the housing 1 is provided with an air blowing channel 2, one end of which extends to the bottom of the housing 1. The adjusting frame 5 is fitted onto the outside of the housing 1. Positioning holes are provided on both sides of the adjusting frame 5, and positioning rods 4 are provided in each positioning hole. One end of each positioning rod 4 is mounted on the outer wall of the housing 1. One end of the adjusting frame 5 is provided with an mounting hole, in which a nozzle 6 is installed. One end of the nozzle 6 extends into the air blowing channel 2. An installation port is provided on the other side of the housing 1, in which a cleaning mechanism is installed. A drive mechanism is installed at one end of the housing 1 to rotate the housing 1, the cleaning mechanism, and the nozzle 6.

[0020] In this embodiment, the cleaning mechanism includes a mounting block 7 and a cleaning layer 9. The mounting block 7 is vertically inserted into the mounting opening. The cleaning layer 9 is installed on one side of the mounting block 7 and extends into the interior of the housing 1 on the other side. Positioning grooves are vertically provided on both sides of the mounting opening. Positioning parts 8 are protruded from both sides of the mounting block 7 and inserted into the positioning grooves.

[0021] In this embodiment, the drive mechanism includes a fixed frame 10, a grip 11, and a motor 12. One end of the grip 11 is provided with a groove, and the motor 12 is installed in the groove. The rotating shaft of the motor 12 extends to the outside through the opening of the groove and is fixedly connected to the fixed frame 10. The two sides of the fixed frame 10 are installed on the two sides of the housing 1. The grip is made of plastic material, which reduces its weight.

[0022] In this embodiment, wind deflectors 3 are installed on both sides of the air blowing channel 2 on the side of the housing 1. The wind deflectors 3 are all L-shaped structures. The wind deflectors increase the blocking effect, so that the gas generated by the nozzle can enter the housing more smoothly and clean it.

[0023] In this embodiment, a battery for powering the motor 12 is installed inside the grip 11, and a switch for controlling the start and stop of the motor 12 is installed on the outer wall of the grip 11. The switch, the battery, and the motor 12 are electrically connected. The grip is also equipped with a charging port for charging the battery, which facilitates charging. The start and stop of the motor can be controlled by the switch. The motor is a geared motor to reduce its rotation speed.

[0024] In this embodiment, the inner side of the adjustment frame 5 is in frictional contact with the outer surface of the housing 1, and the inner ring surface of the positioning hole is in frictional contact with the outer wall surface of the positioning rod 4. The rotating adjustment frame and the nozzle are positioned by friction, so that the nozzle can face various angles.

[0025] In this embodiment, the cleaning layer 9 is a cleaning cotton pad. The cleaning cotton pad can ensure the cleaning quality, and after pulling the mounting block upward, the mounting block can be pulled out from the mounting hole, which facilitates its disassembly and assembly, and also facilitates the replacement of the cleaning layer.

[0026] In use, the housing can be fitted over the nozzle patch head. One side of the cleaning layer can contact the outer surface of the nozzle patch head and rotate around the positioning rod to the adjustment frame. The movement of the adjustment frame drives the nozzle, allowing the nozzle to rotate along the air blowing channel until it is aligned with different positions on the nozzle patch head. The other end of the nozzle is connected to the air pump through a hose. The air generated by the air pump can enter the nozzle through the hose and blow onto the outer surface of the nozzle patch head. The motor can be started by a switch. The start of the motor drives the fixing frame and the housing. The rotation of the housing drives the mounting block, the cleaning layer and the nozzle, allowing the cleaning layer and the nozzle to rotate around the nozzle patch head, thus enabling a thorough cleaning. The adjustment frame can rotate around the shaft. After the motor is turned off, the position of the nozzle can be adjusted again to ensure the quality of cleaning. After the nozzle is vertically set below the housing, the gas generated by the nozzle can be blown into the interior of the suction nozzle patch head to clean its interior.

[0027] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
