Technical Field

[0001] The utility model relates to the technical field of PCB cleaning equipment, in particular to a circulating water-saving device for horizontal electroplating of PCB boards. Background Art

[0002] The subtractive method of making PCBs is to use chemicals or machinery to remove the unnecessary areas on the blank PCB, and the remaining areas are the required circuits. During the production process of PCBs, the electroplating line requires a lot of water for cleaning. The liquid used in the electroplating and the impurities left on the PCB are removed from the PCB, which easily causes a lot of waste of water resources.

[0003] Chinese patent publication number CN210546650U discloses a circulating water-saving device for a horizontal electroplating line of a PCB board. The upper and lower surfaces of the PCB board can be rinsed by an upper nozzle and a lower nozzle, thereby completing the cleaning process. The cleaned PCB board is moved to the top of a drying plate. At this time, the hot air blower works to send hot air into the drying plate, and then the hot air comes out of the drying hole to dry the PCB board. Finally, the cleaned and dried PCB board is taken out by a robot.

[0004] However, the above patent has the following shortcomings:

[0005] The water-saving device only blows hot air from below the PCB board to dry the PCB board, and the moisture remaining on the PCB board can only be removed by evaporation, which has low drying efficiency and causes waste of water resources. Utility Model Content

[0006] The utility model aims to solve the problems existing in the background technology and proposes a circulating water-saving device for horizontal electroplating of PCB boards, which can quickly dry the cleaned PCB boards and reduce the loss of water resources.

[0008] Preferably, the drying mechanism further comprises a hot air blower arranged on the box frame and a ventilation duct for connecting the hot air blower and the air guide boxes on the two sets of drying components.

[0009] Preferably, the air outlet duct is inclined toward the cleaning mechanism and the placement assembly.

[0012] Preferably, the purification component includes a filter component and an activated carbon plate which are sequentially arranged on the box frame from top to bottom.

[0013] Preferably, the filter assembly includes a filter frame slidably arranged on the box frame, a filter plate arranged at the bottom of the filter frame, a connecting plate arranged at the side of the filter frame, and a handle arranged on the connecting plate.

The box frame 1 has a water storage space 101 inside and an opening on the top, and the water resources required for cleaning are stored in the water storage space 101, and the water after cleaning the PCB board flows back to the water storage space 101 through the opening for recycling; the purification component 2 is arranged in the water storage space 101 to purify the used water; the moving mechanism 3 is arranged on the box frame 1; the placement component 4 is arranged on the moving mechanism 3, and the placement component 4 is used to place the PCB board, and the PCB board is driven to move by the moving mechanism 3; the cleaning mechanism 5 is arranged on the box frame 1 and is connected with the water storage space 101, and the cleaning mechanism 5 is used to clean the PCB board;

[0023] The drying mechanism 6 is arranged on the box frame 1, and the drying mechanism 6 includes two groups of drying components 601 symmetrically arranged along the placement component 4. By arranging the upper and lower groups of drying components 601, the upper and lower surfaces of the PCB board can be dried simultaneously, thereby improving the drying efficiency.
