Description

A circuit board deglue spray water circulation system

technical field

The utility model relates to a circuit board deglue spray water circulation system.

Background technique

At present, when processing printed circuit boards, PTH (electroplating) process is required. Hole metallization is a key link in the production process of multilayer boards. It is related to the internal quality of multilayer boards. Hole metallization is divided into de-drilling Two processes of pollution and electroless copper deposition. Electroless copper is the process of interconnecting internal and external circuits, and desmearing is to remove the epoxy resin drilling smear (especially the drilling smear on the copper ring) caused by high temperature during the high-speed drilling process, so as to ensure the circuit connection after electroless copper deposition high reliability. Spraying water washing is required to clean the circuit boards to remove drill stains. In the existing spraying device, the spraying head sprays water continuously, even in the process of changing the circuit boards, it does not stop spraying water, wasting water resources, and The overflowing water in the washing tank is directly drained without recycling, and the utilization rate of water is low.

Utility model content

In order to overcome the deficiencies of the prior art, the utility model provides a circuit board deglue spray water circulation system, which circulates the overflow water and monitors the action of replacing the circuit board, automatically stops spraying, and saves water.

The technical scheme that the utility model solves its technical problem adopts is:

A circuit board deglue spraying water circulation system, including a water washing tank, the water washing tank is provided with a shower head and an overflow tank, a circulation pipeline is arranged between the spray head and the overflow tank, and the circulation pipe A water storage tank, a booster device and a water changing device are arranged in sequence on the road. A board frame for placing circuit boards is arranged in the water washing tank, and a sensor for detecting whether the board placing frame is installed in place is connected to the water washing tank. The inductor is electrically connected to the booster device and sends a signal to the booster device, and the booster device is turned on or off according to the received signal.

As an improvement of the above technical solution, the shower heads are arranged in a single row on the inner wall of the washing tank parallel to the plate placing frame, and the water spray of the shower heads is directed to the upper part of the plate placing frame.

As a further improvement of the above technical solution, the pressure boosting device is a water pump.

Further, the water changing device includes a discharge pipe located at the bottom of the water washing tank and a water supply pipe connected to the circulation pipeline.

The beneficial effects of the utility model are: the sensor detects that the plate frame is placed in place and sends a start signal to the booster device, and the booster device starts after receiving the start signal, and the pressure of the water in the circulation pipeline is raised to perform spraying; When the circuit board is replaced, the board frame is lifted. The sensor detects that the board frame is not placed in place and sends a stop signal to the booster device. The booster device stops after receiving the stop signal to stop spraying, reducing spraying water and saving water resources. ; The water overflowing from the washing tank is stored in the water storage tank as circulating water supply for spraying, which can not only save water resources, reduce dependence on the environment, but also minimize industrial emissions and protect the environment.

Description of drawings

Below in conjunction with accompanying drawing and embodiment the utility model is further described.

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

Detailed ways

Referring to Fig. 1, a circuit board deglue spray water circulation system includes a washing tank 1, the washing tank 1 is provided with a shower head 101 and an overflow tank, and the shower head 101 and the overflow tank are provided with Circulation pipeline 2, said circulation pipeline 2 is provided with water storage tank 3, booster device 4 and water changing device 5 in sequence, said water washing tank 1 is provided with a board frame 6 for placing circuit boards, said water washing The slot 1 is connected with an inductor 7 for detecting whether the board frame 6 is installed in place, the inductor 7 is electrically connected with the booster 4 and sends a signal to the booster 4, and the booster 4 receives The signal is turned on or off. With the above structure, the water overflowing from the washing tank 1 is stored in the water storage tank 3 through the circulation pipeline 2 and used as circulating spray water, which improves the utilization rate of water, reduces water consumption, reduces sewage discharge, and is energy-saving and environmentally friendly; 7. Monitor the state of the board frame 6 at any time. When the board frame 6 is hoisted to replace the circuit board, the sensor 7 sends a stop signal to the booster 4 to stop the boost, thereby stopping the spraying, reducing water and energy, Eliminate the waste caused by the uninterrupted water spraying of the existing sprinklers; on the contrary, when the plate frame 6 is placed in place, the sensor 7 sends a start signal to the booster 4, and the booster 4 starts boosting to spray.
