Abstract

(57) [Summary] [Purpose] More panels can be cleaned quickly and efficiently, and even with complicated shapes, a high cleaning effect can be achieved with a small amount of cleaning water. To provide a washing and washing device. [Structure] The panel 3 is inserted into the cleaning tank 1 and immersed in cleaning water, and air is discharged from the air pipe 5 to perform cleaning while stirring. While the panel that has been cleaned is slowly pulled up from the cleaning tank, a predetermined amount of cleaning water is sprayed onto the panel from the cleaning water spray nozzles 4 arranged on both sides of the upper part of the cleaning tank to perform the final cleaning. At the same time that the cleaning water is sprayed from the nozzle, the drainage pipe 6 arranged at the bottom of the cleaning tank discharges a cleaning liquid of almost the same amount as the cleaning water sprayed from the nozzle to keep the liquid level in the cleaning tank constant.

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an apparatus for washing residual components such as a plating solution adhered on a treated work panel with water.

[0002]

[Prior art]

 Generally, when cleaning a work panel such as a plated PC board, the cleaning tanks are arranged in two stages and three stages, and clean water is supplied from the last stage, and the cleaning water is supplied as the work water. In contrast to the direction of the flannel treatment, the so-called countercurrent method is often used in which the second tank and the first tank are flowed in this order. As another method, there is a spray method in which cleaning water is sprayed from a nozzle and sprayed on a work panel for cleaning.

[0003]

[Problems to be solved by the device]

 The above-mentioned countercurrent cleaning is excellent as a method for efficiently cleaning a large amount of work panels in a short time, but a large amount of water must be countercurrently flowed in order to perform cleaning more completely. Therefore, the amount of water consumed increases and the amount of drainage increases accordingly. In addition, the equipment cost is increased because the washing tank is usually installed in two or three steps, and the installation area of the equipment increases.

On the other hand, the spray method is excellent as a method for performing stable cleaning and requires less installation space because it uses less water and is compact in equipment, but has the ability to highly clean the complicated shape in detail. Has a problem.

Therefore, it is an object of the present invention to treat more panels quickly and efficiently, and particularly to achieve a high cleaning effect with a small amount of cleaning water even with a complicated shape. It is possible to provide a washing and washing device which can be manufactured and requires a small installation area.

[0006]

[Means for Solving the Problems]

 The above purpose is a device for cleaning residual components such as plating solution adhered on the treated work panel by rinsing with water, and a cleaning tank filled with the minimum cleaning water necessary for cleaning the panel, A nozzle for spraying cleaning water arranged so that the panel is sandwiched from both sides without contacting the top of the cleaning tank, an air pipe for discharging stirring air arranged at the bottom of the cleaning tank, and a bottom portion of the cleaning tank. It also consists of a drainage pipe, and while washing the cleaned panel from the cleaning tank, it sprays fresh cleaning water from the above nozzle to clean both sides of the panel, and the same amount of sprayed cleaning water as the cleaning tank. It was achieved by a cleaning device characterized by discharging from a drainage pipe located at the bottom.

【Example】

 An embodiment of the washing and washing apparatus according to the present invention will be described below with reference to the drawings. FIG. 1 shows a cross section of the washing and washing apparatus according to the present invention. The apparatus includes a cleaning tank 1, an outer peripheral tank 2 surrounding the cleaning tank, a cleaning water jet nozzle 4 arranged so as to sandwich the work panel 3 on both sides of the cleaning tank without coming into contact with each other, and a lower portion of the cleaning tank. It is composed of an air pipe 5 for discharging stirring air and a drain pipe 6 arranged at the bottom of the cleaning tank. First, insert the panel 3 supported by the rack from the upper part of the cleaning tank 1 filled with the minimum amount of cleaning water necessary for cleaning the panel and immerse it in the cleaning water to increase the cleaning effect. Air is discharged from the air pipe 5 arranged at the lower part to wash with stirring. The panel that has been cleaned is slowly pulled up from the cleaning tank, and a predetermined amount of cleaning water is sprayed onto the panel from the cleaning water spray nozzles 4 arranged on both sides of the upper part of the cleaning tank to perform the final cleaning. At the same time as washing water is sprayed from the nozzle, the drain pipe 6 located at the bottom of the washing tank discharges approximately the same amount of washing liquid as the washing water sprayed from the nozzle to keep the level of the washing tank constant. To

[Effect of device]

 With the washing and cleaning apparatus of the present invention, more panels can be processed quickly and efficiently, and in particular, even with a complicated shape, a high washing effect can be achieved with a small amount of washing water. Further, since the device of the present invention is remarkably miniaturized, the installation area of the device is smaller than that of the conventional cleaning device. Another advantage is that the amount of cleaning liquid discharged is greatly reduced compared to the conventional method, so the cost of treating the waste liquid is small, and even when recovering the plating liquid, it is cheaper. Can be collected.

Claims (1)

[Scope of utility model registration request] 1. An apparatus for washing residual components such as a plating solution adhering to a treated work panel by washing with water.
A cleaning tank filled with the minimum amount of cleaning water required to clean the panel, a nozzle for spraying cleaning water arranged so as to sandwich the panel from both sides at the top of the cleaning tank, and at the bottom of the cleaning tank It consists of an air pipe that discharges agitation air and a drain pipe that is placed at the bottom of the cleaning tank. While pulling up the cleaned panel from the cleaning tank, spraying fresh cleaning water from the above nozzle to clean both sides of the panel. In addition, the cleaning device discharges the same amount of water as the sprayed cleaning water from the drain pipe arranged in the lower part of the cleaning tank.
