[0030] refer to Figures 1 to 3As shown, the utility model discloses a cleaning device for PCB boards, comprising:

[0031] A cleaning station 1, wherein a profiling mold 3 is provided on the cleaning station 1, and the profiling mold 3 is used to place a PCB board;

[0032] A dry ice blasting head 4, which is movably disposed above the cleaning station 1;

[0033] an ion generator 5, which is movably disposed above the cleaning station 1 and staggered with the dry ice spray head 4;

[0034] When cleaning the PCB board, the dry ice jet head 4 and the ion generator 5 respectively spray fluids to the PCB board.

[0035] Compared with the prior art, the utility model discloses a cleaning device for PCB boards, which innovatively simultaneously arranges a dry ice jet head 4 and an ion generator 5 to clean the PCB boards, uses the fixed carbon dioxide particles sprayed by the dry ice jet head 4 to clean the rosin, oil stains and solder on the PCB boards, uses the ion generator 5 to replace the brush, and uses the ionized gas sprayed by the ion generator 5 to remove static electricity, dust on the PCB boards, and moisture formed on the PCB boards due to the cold fluid sprayed by the dry ice jet head 4, so the cleaning quality is high.

[0036] In one embodiment, the cleaning equipment for PCB board includes a moving device 6, the dry ice blasting head 4 and the ion generator 5 are installed on the moving device 6, and the moving device 6 drives the dry ice blasting head 4 and the ion generator 5 to move, so as to control the position of the fluid sprayed by the dry ice blasting head 4 and the ion generator 5 during the cleaning process, so that the fluid sprayed by the dry ice blasting head 4 and the ion generator 5 can fully act on the surface of the PCB board, thereby comprehensively and effectively cleaning the surface of the PCB board.

[0037] In one embodiment, the moving device 6 has an X-axis linear module, which is arranged above the cleaning station 1. The X-axis linear module is connected to the dry ice blasting head 4 and the ion generator 5 at the same time to drive the dry ice blasting head 4 and the ion generator 5 to perform linear reciprocating motion in the horizontal direction to control the position of the dry ice blasting head 4 and the ion generator 5 spraying fluid along the X-axis direction.

[0038] In one embodiment, the moving device 6 also has a Z-axis linear module, which is installed on the driving end of the X-axis linear module. The dry ice spray head 4 and the ion generator 5 are fixedly installed on the driving end of the Z-axis linear module at the same time. The Z-axis linear module drives the dry ice spray head 4 and the ion generator 5 to perform linear reciprocating motion in the vertical direction to control the position of the dry ice spray head 4 and the ion generator 5 spraying fluid along the Z-axis direction.

[0039] After the X-axis linear module and the Y-axis linear module are used to drive the dry ice jet head 4 and the ion generator 5, the cleaning device for PCB boards can be applied to PCB boards of different specifications and has high versatility.

[0040] In addition, in addition to using the combination of the above-mentioned X-axis linear module and the Z-axis linear module to synchronously drive the dry ice blasting head 4 and the ion generator 5 to move, the moving device 6 can also use an industrial robot to drive the dry ice blasting head 4 and the ion generator 5 to move.

[0041] In one embodiment, the cleaning device for PCB boards further comprises a station to be cleaned 2 and a workpiece conveying device 7; the workpiece conveying device 7 drives the profiling mold 3 to reciprocate between the station to be cleaned 2 and the cleaning station 1. The employee places the PCB board at the station to be cleaned 2, and uses the workpiece conveying device 7 to move the PCB board to the cleaning station 1 for cleaning, thereby preventing the employee from directly placing the PCB board at the cleaning station 1, thereby effectively preventing the dry ice jet head 4 from being accidentally triggered and spraying cold carbon dioxide solid particles on the employee's hand to cause a safety accident.

[0042] Preferably, the workpiece conveying device 7 is a linear module, which drives the profiling die 3 to perform linear reciprocating motion along the Y-axis direction.

[0043] Furthermore, the number of the cleaning station 1, the station to be cleaned 2 and the workpiece conveying device 7 is two, so that continuous alternating cleaning work can be performed, effectively improving the cleaning efficiency.

[0044] Furthermore, the cleaning equipment for PCB boards also includes a protective cover 8, which is arranged on the outside of the dry ice blasting head 4 and the ion generator 5, and the lower side of the protective cover 8 is opened to protect the dry ice blasting head 4 and the ion generator 5, so as to prevent employees from placing other objects on the profiling mold 3 due to mistakes. After the workpiece conveying device 7 is started, when the object is conveyed from the pre-cleaning station 1 to the cleaning station 1, the object directly collides with the dry ice blasting head 4 and the ion generator 5, causing damage to the dry ice blasting head 4 and the ion generator 5. The protective cover 8 separates other objects from the dry ice blasting head 4 and the ion generator 5, and effectively protects the dry ice blasting head 4 and the ion generator 5 from damage.

[0045] Preferably, there is a space between the protective cover 8, the dry ice blasting head 4 and the ion generator 5 for the protective cover 8 to be recessed inward, so that even if the protective cover 8 is deformed by a collision, the deformed part of the protective cover 8 is unlikely to squeeze the dry ice blasting head 4 and the ion generator 5, thereby effectively protecting the dry ice blasting head 4 and the ion generator 5.

[0046] The 4-channel pipeline of the dry ice blasting head is connected to an external dry ice particle supply device.

[0047] The present invention is not limited to the above-mentioned embodiments. If various changes or modifications to the present invention do not depart from the spirit and scope of the present invention, and if these changes and modifications fall within the claims of the present invention and the scope of equivalent technologies, the present invention is also intended to include these changes and modifications.
