Description

PCB board cleaning booster

technical field

The utility model relates to surface mount technology (SMT), in particular to a PCB board cleaning supercharger.

Background technique

At present, there are many foreign objects on the surface of the PCB board after patching, which needs to be cleaned. The cleaning machine in the prior art is mainly composed of the body of the cleaning machine and a rotating disk located on the upper part of the body. The slot, the PCB board can be installed in the slot, and a water spray pipe is arranged above the rotating disc. When the rotating disk rotates, it drives the PCB board inserted in the slot to rotate, and the water spray pipe sprays water to complete the cleaning work of the PCB board. Due to the relatively low water pressure design in the current water spray pipe, the foreign matter on the surface of the PCB cannot be completely removed during spraying, resulting in a decrease in the yield of the product.

Utility model content

The purpose of the utility model is to overcome the deficiencies of the above-mentioned technologies, and provide a PCB board cleaning supercharger, which can achieve the purpose of high-pressure cleaning of foreign matter on the PCB board by pressurizing the water in the water spray pipe.

In order to achieve the above object, the utility model adopts the following technical solutions: a PCB board cleaning supercharger, including a cleaning machine body with a rotating disc, above which a water spray pipe for cleaning the PCB board is arranged, and its features In that: the water outlet end of the water spray pipe is connected with a three-way joint, the water outlet end of the water spray pipe communicates with the middle interface in the three-way joint, and the other two ends of the three-way joint are respectively connected with an air pipe and a nozzle.

The trachea is provided with a regulating valve for adjusting the size of the airflow.

Beneficial effects: The utility model is simple in structure and easy to operate. By connecting an air pipe in parallel with the water spray pipe, the water pressure in the water spray pipe is increased, foreign matter on the PCB board can be effectively removed, and the qualified rate of the product is improved.

Description of drawings

Fig. 1 is a structural representation of the utility model.

Detailed ways

The specific implementation of the utility model will be described in detail below in conjunction with the accompanying drawings and preferred embodiments. As shown in the figure, a PCB board cleaning supercharger includes a cleaning machine body 1 with a rotating disk, and a water spray pipe 2 for cleaning the PCB board is arranged above the rotating disk. The water outlet end of the water spray pipe is connected with a tee joint 3, and in order to better achieve the spraying effect, the water outlet end of the water spray pipe communicates with the middle joint of the tee joint. One of the other two ports of the tee joint is connected to an air pipe 4 connected to an external air source, and the other port is connected to a spray head 5 . In order to control the water pressure in the water spray pipe, the air pipe is provided with a regulating valve 6 for adjusting the size of the airflow. The purpose of controlling the water pressure is achieved by indirectly controlling the airflow. The utility model has the advantages of simple structure and convenient operation. By connecting an air pipe in parallel with the water spray pipe, the water pressure in the water spray pipe is increased, the foreign matter on the PCB board can be effectively removed, and the qualified rate of the product is improved.

The above is only a preferred embodiment of the utility model, it should be pointed out that for those of ordinary skill in the art, without departing from the principle of the utility model, some improvements and modifications can also be made, these improvements and Retouching should also be regarded as the scope of protection of the present utility model.
