Description

Technical Field

[0001] This invention relates to the field of waterproof membrane production, and particularly to equipment and manufacturing process for rapidly forming waterproof membranes on the surface of circuit boards. Background Art

[0002] Waterproof membranes are mainly made of fluorides and have two processing methods: immersion and vacuum coating. Vacuum coating is the more common method. After the anti-reflective coating is completed, fluorides can be deposited onto the reflective film using an evaporation process. The anti-fouling film can cover the porous anti-reflective coating and reduce the contact area between water and oil and the lens, making it difficult for oil and water droplets to adhere to the lens surface. Therefore, it is also called a waterproof membrane.

[0003] Circuit boards are also known as ceramic circuit boards, alumina ceramic circuit boards, aluminum nitride ceramic circuit boards, circuit boards, PCB boards, aluminum substrates, high-frequency boards, thick copper boards, impedance boards, PCBs, ultra-thin circuit boards, ultra-thin circuit boards, printed circuit boards, etc. Circuit boards make circuits miniaturized and more intuitive, playing an important role in the mass production of fixed circuits and the optimization of electrical appliance layout. Circuit boards can also be called printed circuit boards or printed circuit boards. After the circuit board is produced, most of them need to be coated with a waterproof film. After the waterproof film is prepared, it needs to be collected and installed on the circuit board using other equipment, which is cumbersome and inefficient.

Specific Implementation Example 2:

[0035] like Figure 1 As shown, the manufacturing process for rapidly forming a waterproof film on the surface of a circuit board includes the following steps:

[0036] S1: Preparation of PVDF solution: Place the four-necked flask stably in the ring pad, tare and zero the precision electronic analytical balance, slowly pour in the solution using a guide rod, and finally add DMAc liquid to 82 grams using a dropper. Insert the stirrer, seal the four-necked flask with a glass stopper, and place it on the pre-set constant temperature oil bath heating equipment. Set the temperature of the oil bath to 70 degrees Celsius, turn on the stirring motor, and when the oil temperature reaches 70 degrees Celsius, weigh 18 grams of PVDF powder using weighing paper on the precision electronic analytical balance, add it to the four-necked flask through a funnel, and use a wash bottle to blow the PVDF powder adhering to the surface of the funnel into the four-necked flask. After six hours of vigorous stirring, a homogeneous, clear, pale yellow solution of 18% PVDF is prepared.

[0037] S2: Electrospinning preparation operation: 10 ml of PVDF solution is drawn into the injection syringe 10 and loaded into the spinning device 6. The solution injection speed of the micro-injection pump 7 is adjusted to 3 mL / h, the receiving distance is 24 cm, the rotation speed of the first roller 19 is 50 rpm, the moving speed of the spinning device 6 is set to 100 cm / min, and the receiving substrate is glossy paper.

One end of the waterproof membrane is fixed to the outer wall of the third roller 35. The two second mounting components 27 are separated, and the circuit board is placed between them. After releasing the second mounting components 27, the second spring 26 will spring the two second mounting components 27 towards both ends of the circuit board, thus achieving a clamping effect. The third servo motor 22 is activated, driving the second threaded rod 24 to move within the inner cavity of the second movable groove 23, allowing the bottoms of the two moving components 31 to be threadedly connected to the outer wall of the second threaded rod 24. This moves the second roller 32 to the left side of the top of the circuit board. The second bolt 34 is loosened, and the second roller 32 is moved to the bottom, allowing the bottom of the second roller 32 to adhere the waterproof membrane to the top of the circuit board. The third servo motor 22 is activated again, causing the moving components 31 to drive the second roller 32 to reciprocate, ensuring the waterproof membrane is completely adhered to the top of the circuit board. After adhesion, the waterproof membrane is cut off, and the process is repeated.

9. The manufacturing process of the waterproof membrane used in the equipment for rapidly forming a waterproof membrane on the surface of a circuit board according to claim 1, characterized in that: The following steps are included: S1: Preparation of PVDF solution: Place the four-necked flask stably in the ring pad, tare and zero the precision electronic analytical balance, slowly pour in the solution using a guide rod, and finally add DMAc liquid to 82 grams using a dropper. Insert the stirrer, seal the four-necked flask with a glass stopper, and place it on the pre-set constant temperature oil bath heating equipment. Set the temperature of the oil bath to 70 degrees Celsius, turn on the stirring motor, and when the oil temperature reaches 70 degrees Celsius, weigh 18 grams of PVDF powder using weighing paper on the precision electronic analytical balance, add it to the four-necked flask through a funnel, and use a wash bottle to blow the PVDF powder adhering to the surface of the funnel into the four-necked flask. After six hours of vigorous stirring, a homogeneous clear pale yellow solution of 18% PVDF is prepared. S2: Electrospinning preparation operation: The injection syringe (10) is used to draw 10 ml of PVDF solution and load it into the spinning equipment (6). The solution injection speed of the micro-injection pump (7) is adjusted to 3 mL / h, the receiving distance is 24 cm, the rotation speed of the first roller (19) is 50 rpm, the moving speed of the spinning equipment (6) is set to 100 cm / min, and the receiving substrate is glossy paper. When the ambient temperature is 23 ± 3℃ and the relative humidity is 45 ± 15%, the preparation can be carried out. Finally, the obtained PVDF nanofiber membrane is placed in a vacuum oven at 70℃ for 2 h to remove the residual organic solvent in the fiber membrane, thus completing the preparation.
