Problems solved by technology

The traditional washing method is continuous multi-stage countercurrent washing. When the board enters the liquid medicine tank, the control system will immediately open the overflow water device to replenish new water to the washing tank. After the board leaves the washing tank, the control system will control the overflow water supply device to stop replenishing water. This function of "replenishing water with the board and shutting down without the board" seems to achieve the purpose of saving water, but it is actually impossible to evaluate whether the board has been cleaned, and it is also impossible to evaluate whether the purpose of cleaning the board surface is achieved with the least amount of water. At present, There is no good solution in the industry

Abstract

The invention discloses a PCB washing cylinder overflow device which comprises a water inlet, an overflow port and a water inlet; the water inlet is connected with the water inlet system through a pipeline; the overflow port is connected with an external blow-off pipe through a pipeline; and the overflow port is formed in the washing cylinder and is lower than all washing nozzles; the water inletis formed in the washing cylinder and is lower than the overflow port; a water quality monitoring device is further included, and comprises a water quality monitoring sensor, an electromagnetic valveand an online control interface; and the electromagnetic valve is arranged on a connecting pipeline of the water inlet and the water inlet system, and the water quality monitoring device controls starting and stopping of the water inlet of an overflow device through the water quality monitoring sensor. A PCB washing device comprises the washing cylinder, a transmission device, a spraying device and any PCB washing cylinder overflow device, the conveying device is arranged in the washing cylinder, and the washing nozzle in the spraying device is arranged over the conveying device. The structureis simple, and water can be effectively saved.

Description

Technical field [0001] The present invention relates to the field of PCB board manufacturing, and more particularly, to a PCB board water washing tank overflow device and a PCB board water washing device composed of it. Background technique [0002] In the PCB production process, the horizontal line belongs to one of the most water-consuming sections. The biggest aspect of the horizontal line is the overflow of each washing tank every day. The purpose of washing is to dilute the potion and clean the board from the front potion tank. Board surface. The traditional water washing method is continuous multi-stage countercurrent washing. When the board enters the potion tank, the control system immediately turns on the overflow water device to start refilling the water washing tank. After the board leaves the water washing tank, the control system will control the overflow water replenishment device to stop refilling. This function of "replenish water with board and stop without boar...
