Description

Technical Field

[0001] This application relates to the field of circuit board lamination technology, and more specifically, to a water supply device for circuit board water-soluble lamination. Background Technology

[0002] As circuitry becomes increasingly dense with smaller spacing and pads, multi-layer circuitry is required. This necessitates multiple electroplating and lamination processes, which increase the complexity of the process and the greater the probability of surface dents and scratches. These dents and scratches directly impact the quality and yield of circuit boards, including open circuits and gaps. Lamination is a crucial step in the circuit pattern transfer process. Traditional lamination methods often result in gaps at dent / scratched locations, leading to open circuits and gaps during subsequent etching processes. Currently, wet lamination processes suffer from unstable water supply.

[0003] The current water-soluble membrane pressing water supply device uses a direct municipal water supply method, which is greatly affected by the water consumption of other equipment and the water pressure at the front end. If the water supply is too small, the amount of water applied will be insufficient, and the filling effect of replacing the dry membrane will not be achieved. If the water supply is too large, the water volume will increase, affecting the membrane pressing effect. At the same time, excess water may overflow into the equipment, causing damage to the equipment. Further improvements can be made.

[0004] To address the aforementioned issues, this application provides a water-soluble pressure film water supply device for circuit boards. Utility Model Content

[0005] The water-soluble pressure film water supply device for circuit boards provided in this application adopts the following technical solution:

[0006] A water-soluble pressure membrane water supply device for circuit boards includes a water supply tank and a pump box. The pump box is fixedly installed at one end of the water supply tank, and a constant pressure water pump is fixedly installed inside the pump box. The input end of the constant pressure water pump is connected to the bottom of the water supply tank through a water pumping pipe. The output end of the constant pressure water pump is connected to an outlet pipe, and the other end of the outlet pipe is connected to a diverter pipe. The other end of the diverter pipe is connected to a quick connector. The other end of the water supply tank is connected to an inlet pipe, and a solenoid valve is installed on the surface of the inlet pipe. A level switch is installed inside the water supply tank.

[0007] Through the above technical solution, the constant pressure water pump is an existing device that can be purchased on the market. The constant pressure water pump has a stable pressure output, which can ensure the stability of water pressure. Pure water is pumped to the water supply tank. The constant pressure water pump draws pure water from the water supply tank through the water pumping pipe and enters the distribution pipe through the water outlet pipe. The quick connector connects to the spray frame of the coating wheel through the connecting pipe. The constant pressure water supply stabilizes the water pressure, thereby stabilizing the spray water pressure, improving the stability of the water supply to the coating wheel, improving the stability of the coating wheel's work on the circuit board lamination, and improving work efficiency.

[0008] Furthermore, the output terminal of the liquid level switch is electrically connected to the input terminal of the solenoid valve, and one end of the water inlet pipe is connected through to the bottom of the water supply tank.

[0009] With the above technical solution, when the level switch detects that the pure water level inside the water supply tank is low, the solenoid valve opens, and pure water is replenished into the water supply tank. After reaching the set maximum level, the solenoid valve closes.

[0010] Furthermore, the other end of the water inlet pipe is connected to a pure water pumping device, and the input end of the pure water pumping device is electrically connected to the output end of the liquid level switch.

[0011] Through the above technical solution, the solenoid valve and the pure water pumping equipment open and close synchronously. When there is a water shortage, the pure water pumping equipment starts to pump water. After reaching the set maximum liquid level, the pure water pumping equipment shuts down. A liquid level switch is installed inside the water supply tank to control the liquid level inside the water supply tank, thereby controlling the water pressure inside the water supply tank, which further plays a role in stabilizing the pressure and further reduces the impact of water supply fluctuations on water pressure.

[0012] Furthermore, the diversion pipe adopts a Y-shaped structure, and the other end of the diversion pipe is connected to a connecting pipe through a quick connector, and the other end of the connecting pipe is connected to the sprinkler frame of the water wheel.

[0013] Through the above technical solution, the Y-shaped diversion pipe facilitates uniform diversion, thereby improving the consistency and stability of water pressure after diversion. The sprinkler frame connecting the pipe and the water wheel is a common structure in this field and will not be described in detail here.

[0014] Furthermore, the water supply tank has a door hinged to its front facade, and sound insulation cotton is adhered to both the inner wall of the water supply tank and the inner wall of the door.

[0015] Through the above technical solution, the sound insulation cotton is no less than 5cm thick, and the box door and pump box play a protective role, preventing non-staff members from accidentally operating the constant pressure water pump. At the same time, the sound insulation cotton pasted on the inner wall of the pump box plays a sound insulation role, resulting in less operating noise and greater ease of use.

[0016] Furthermore, the outlet pipe is connected to the diversion pipe via a flange, and the diversion pipe extends through and out of the pump box.

[0017] The above technical solution utilizes flanges, a common type of pipe connection, which facilitates the installation of distribution pipes.

[0018] Furthermore, the water supply tank has a sealed structure.

[0019] The above technical solution prevents impurities from entering the sealed water supply tank, thus avoiding contamination of the pure water.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] It adopts a constant pressure water pump and a water supply tank. The inlet pipe is connected to a pure water supply pump, which pumps pure water to the water supply tank. The constant pressure water pump draws pure water from the water supply tank through the pumping pipe, and the pure water enters the distribution pipe through the outlet pipe. The quick connector connects to the spray frame of the coating wheel through the connecting pipe. The constant pressure water supply stabilizes the water pressure, thereby stabilizing the spraying water pressure and improving the stability of the water supply to the coating wheel. This improves the stability of the coating wheel's work on the circuit board lamination and increases work efficiency. At the same time, a liquid level switch is installed inside the water supply tank to control the liquid level inside the tank, thereby controlling the water pressure inside the tank and further stabilizing the pressure. This further reduces the impact of water supply fluctuations on the water pressure. In addition, the inner wall of the pump box is lined with sound insulation cotton, which has a sound insulation effect, resulting in lower operating noise and greater ease of use.

A quick connector 10 is connected to the other end of the diverter pipe 9. An inlet pipe 3 is connected to the other end of the water supply tank 1, and a solenoid valve 4 is installed on the surface of the inlet pipe 3. A liquid... The position switch 2 and constant pressure water pump 6 are existing equipment and can be purchased on the market. The constant pressure water pump 6 has a stable pressure output, which can ensure the stability of water pressure. Pure water is pumped to the water supply tank 1. The constant pressure water pump 6 draws pure water from the water supply tank 1 through the water suction pipe 7, and enters the diversion pipe 9 through the water outlet pipe 8. The quick connector 10 connects to the spray frame of the water coating wheel through the connecting pipe. The constant pressure water supply stabilizes the water pressure, thereby stabilizing the spray water pressure, improving the stability of the water supply to the water coating wheel, improving the stability of the water coating wheel's work on the circuit board, and improving work efficiency.

[0033] Please see Figure 1 The output terminal of the level switch 2 is electrically connected to the input terminal of the solenoid valve 4. One end of the water inlet pipe 3 is connected to the bottom of the water supply tank 1. When the level switch 2 detects that the pure water level inside the water supply tank 1 is low, the solenoid valve 4 opens, and pure water is added into the water supply tank 1. After reaching the set maximum level, the solenoid valve 4 closes.

[0034] Please see Figure 1 The other end of the inlet pipe 3 is connected to the pure water pumping equipment, and the input end of the pure water pumping equipment is electrically connected to the output end of the level switch 2. The solenoid valve 4 opens and closes synchronously with the pure water pumping equipment. When there is a water shortage, the pure water pumping equipment starts to pump water. After reaching the set maximum level, the pure water pumping equipment closes. The level switch 2 is installed inside the water supply tank 1 to control the liquid level inside the water supply tank 1, thereby controlling the water pressure inside the water supply tank 1, which further plays a role in stabilizing the pressure and further reduces the impact of water supply fluctuations on the water pressure.

[0035] Please see Figure 1 and Figure 3 The diversion pipe 9 adopts a Y-shaped structure, and the other end of the diversion pipe 9 is connected to a connecting pipe through a quick connector 10.

The connecting pipe and the sprinkler frame of the water wheel are common structures in this field and will not be described in detail here.

[0036] Please see Figure 1 and Figure 2 The water supply tank 1 has a hinged door 12 on its front facade. Both the inner wall of the water supply tank 1 and the inner wall of the door 12 are covered with sound insulation cotton 11, which is at least 5cm thick. The door 12 and the pump box 5 serve a protective function to prevent unauthorized personnel from accidentally operating the constant pressure water pump 6. At the same time, the sound insulation cotton 11 attached to the inner wall of the pump box 5 provides sound insulation, resulting in lower operating noise and greater ease of use.

[0037] Please see Figure 1 and Figure 4 The outlet pipe 8 is connected to the diversion pipe 9 through the flange 13, and the diversion pipe 9 extends through the pump box 5. The flange 13 is a common pipe connection form, which facilitates the installation of the diversion pipe 9.

[0039] The implementation principle of this embodiment is as follows: During use, the inlet pipe 3 is connected to the pure water supply pump, and the pure water is pumped into the water supply tank 1. The constant pressure water pump 6 draws out the pure water from the water supply tank 1 through the pumping pipe 7, and enters the diversion pipe 9 through the outlet pipe 8. The quick connector 10 is connected to the spray frame of the coating wheel through the connecting pipe. The constant pressure water supply stabilizes the water pressure, thereby stabilizing the spraying water pressure, improving the stability of the water supply of the coating wheel, improving the stability of the coating wheel's work on the circuit board, and improving work efficiency. At the same time, a liquid level switch 2 is installed inside the water supply tank 1 to control the liquid level inside the water supply tank 1, thereby controlling the water pressure inside the water supply tank 1, which further plays a role in stabilizing the pressure and further reduces the impact of water supply fluctuations on the water pressure. In addition, the inner wall of the pump box 5 is pasted with sound insulation cotton 11, which plays a role in sound insulation, resulting in less operating noise and greater ease of use.
