Description

Technical Field

[0001] This utility model relates to the field of photoresist dry film production technology, and in particular to a film surface pressing device under vacuum conditions. Background Technology

[0002] In the circuit board manufacturing industry, with the development of the electronics industry, the circuit lines of electronic circuits and chip circuits are becoming more and more refined, and the gaps between copper wires are becoming smaller and smaller, with micron-level and even nanometer-level lines. Especially in the manufacturing of chips, various functional films, such as solder resist films and insulating films, need to be attached to the gaps between copper wires.

[0003] The core of the vacuum laminator consists of two 500kg stainless steel laminating plates. The circuit board is laminated as it passes between the two platforms. The pressure during lamination reaches approximately 50 tons. Currently, an oil pump in conjunction with a hydraulic cylinder is used to support the lower laminating platform. However, the oil pump is noisy and causes oil mist pollution in the production environment, affecting production personnel and product yield. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a gas-liquid conversion booster system for vacuum film presses. The booster system achieves boosting through gas-liquid conversion, thereby solving the problems caused by the use of oil pumps in the prior art, such as high noise, easy generation of oil mist that pollutes the production space environment, and impacts production personnel and product yield. This system is conducive to stable and efficient production.

[0005] The objective of this utility model is achieved through the following technical solution:

[0006] This utility model provides a gas-liquid conversion booster system for a vacuum film press, including a booster, an oil storage chamber, a booster rod, a pressure reducing valve, a hydraulic cylinder, a pressure gauge, a booster control solenoid valve, a pre-pressure control solenoid valve, a booster rod retraction speed control valve, a pre-pressure exhaust speed control valve, and a hydraulic cylinder exhaust speed control valve.

[0007] The lower chamber of the booster is an oil reservoir for storing hydraulic oil. The booster rod is located in the upper chamber of the booster. The booster is provided with ports P1, P2, and P3 as inlet and outlet ports. Ports P1 and P2 are located above and below the booster rod, respectively, and port P3 is located above the oil reservoir.

[0008] The oil storage chamber is connected to the hydraulic cylinder via an oil pipe; the air source is connected to the boost control solenoid valve and the pre-pressure control solenoid valve via the main air circuit; the boost control solenoid valve is connected to the P1 port and P2 port of the booster 1 via pipelines; the pre-pressure control solenoid valve 8 is connected to the P3 port of the booster 1 and the inlet and outlet port P4 port of the hydraulic cylinder 5 via pipelines.

[0009] The pressure reducing valve is installed on the main air line; the pressure gauge is installed on the oil pipe; the booster rod retraction speed control valve, the pre-pressure exhaust speed control valve, and the hydraulic cylinder exhaust speed control valve are respectively installed on the pipelines of port P1, port P3, and port P4.

[0010] This utility model has the following beneficial effects:

[0011] (1) The gas-liquid conversion method provided by this utility model does not have high-speed rotating mechanical parts, and the hydraulic oil will not splash or overheat, thus eliminating the problem of oil mist generation; since the action is done by gas and liquid, there is no friction and vibration of high-power motor or high-speed rotating mechanical parts, and the lifting speed can be adjusted within an acceptable range, thus effectively solving the noise problem.

[0012] (2) This utility model can control the rapid lifting and lowering of the hydraulic cylinder, thereby supporting the lifting and lowering of a stainless steel pressing mold weighing 500kg, and can generate a supporting force of 50 tons. Attached Figure Description

[0016] Figure 1 The image shows an embodiment of a gas-liquid conversion booster system for a vacuum film press according to the present invention.

[0017] like Figure 1 As shown, the booster system includes a booster 1, an oil reservoir 2, a booster rod 3, a pressure reducing valve 4, a hydraulic cylinder 5, a pressure gauge 6, a booster control solenoid valve 7, a pre-pressure control solenoid valve 8, a booster rod retraction speed control valve 9, a pre-pressure exhaust speed control valve 10, a hydraulic cylinder exhaust speed control valve 11, and a solenoid valve base 12.

[0018] The lower chamber of the booster 1 is an oil reservoir 2 for storing hydraulic oil. The booster rod 3 is located in the upper chamber of the booster 1. The booster 1 is provided with ports P1, P2, and P3 as inlet and outlet ports. Ports P1 and P2 are located above and below the booster rod 3, respectively, and port P3 is located above the oil reservoir 2.

[0019] The oil reservoir 2 is connected to the hydraulic cylinder 5 via oil pipe 13; the air source is connected to the booster control solenoid valve 7 and the pre-pressure control solenoid valve 8, which are mounted on the solenoid valve base 12, via the main air passage 14; the booster control solenoid valve 7 is connected to the P1 port and P2 port of the booster 1 via the first pipeline 15-1 and the second pipeline 15-2, respectively; the pre-pressure control solenoid valve 8 is connected to the P3 port of the booster 1 and the inlet / outlet port P4 of the hydraulic cylinder 5 via the third pipeline 15-3 and the fourth pipeline 15-4, respectively. The pressure reducing valve 4 is mounted on the main air passage 14; the pressure gauge 6 is mounted on the oil pipe 13; the booster rod retraction speed control valve 9, the pre-pressure exhaust speed control valve 10, and the hydraulic cylinder exhaust speed control valve 11 are mounted on the first pipeline 15-1, the third pipeline 15-3, and the fourth pipeline 15-4, respectively.

[0020] Its working principle is as follows:

[0021] The upward stroke of hydraulic cylinder 5 is as follows: Compressed air enters from the main air passage 14, and through the pre-pressure control solenoid valve 8, it enters the booster 1 from port P3 via the third pipeline 15-3. The compressed air forces the hydraulic oil in the oil reservoir 2 into hydraulic cylinder 5 through oil pipe 13, achieving rapid upward movement of hydraulic cylinder 5. The upward speed can be controlled by hydraulic cylinder exhaust speed control valve 11. Then, the boost control solenoid valve 7 causes compressed air to enter from port P1 and exhaust from port P2 of booster 1, causing the booster rod 3 to descend, thereby increasing the pressure of the oil circuit.

[0022] The pressure boosting principle of the oil circuit is as follows: the upper force-bearing area S1 of the booster rod 3 is larger, and the lower area S2 is smaller. According to the relationship between pressure and force, F = PS (F is pressure, P is air pressure, and S is the force-bearing area), the pressure generated below the booster rod will be a multiple of S1 / S2. By adjusting the pressure of P1 entering the booster 1 through the pressure reducing valve 4, the oil circuit can obtain a corresponding multiple of pressure. The pressure in the oil pipe will be displayed in the pressure gauge 6.

[0023] The descent stroke of hydraulic cylinder 5 is as follows: by operating the booster control solenoid valve 7, compressed air is introduced through the second pipeline 15-2 from port P2 of booster 1 and exhausted through port P1, causing booster rod 3 to retract. The retraction speed can be controlled by booster rod retraction speed control valve 9. At the same time, by operating the pre-pressure control solenoid valve 8, compressed air is introduced through the fourth pipeline 15-4 from port P4 of hydraulic cylinder 5, causing hydraulic cylinder 5 to descend. Hydraulic oil is pressed into the oil storage chamber 2 of booster 1 through oil pipe 13. The descent speed of hydraulic cylinder 5 can be controlled by pre-pressure exhaust speed control valve 10.
