Some embodiments will be described below with reference to the accompanying drawings. The embodiments described below and the features of the embodiments can be combined with each other without conflict.

Referring to fig. 1, an embodiment of the present disclosure provides a gas control system 100, which includes a receiving chamber 10, a pressure increasing member 20, a gas storage tank 22, and a vacuum pumping unit 30. The pressurizing member 20 is connected to the air supply member 26 for pressurizing the air supply inputted from the air supply member 26. The air storage tank 22 is communicated with the pressurizing member 20 and the accommodating cavity 10 for storing the pressurized air source. The pressurizing part 20 is connected with the air storage tank 22 through an air pipe, and the air storage tank 22 is connected with the accommodating cavity 10 through an air pipe.

The accommodating chamber 10 includes a first chamber 11 and a second chamber 12. The first chamber 11 is in communication with the air reservoir 22, and the second chamber 12 is movable with respect to the first chamber 11 to close the first chamber 11 as a whole. The accommodating chamber 10 is divided into a first sealed chamber 111 and a second sealed chamber 121 by a diaphragm. The first sealed cavity 111 is a space formed between the first chamber 11 and the diaphragm 300, and the second sealed cavity 121 is a space formed between the second chamber 12 and the diaphragm 300.

The first chamber 11 is connected with the air storage tank 22 through an air pipe, and the air storage tank 22 is communicated with the first sealing cavity 111. The first chamber 11 is hollow and has an opening on the side facing the second chamber 12.

The second chamber 12 is hollow and has an opening on the side facing the first chamber 11. The first chamber 11 and the second chamber 12 are adapted in their contour so that the first chamber 11 and the second chamber 12 form a unitary structure when closed. The diaphragm 300 is disposed at a connection position of the first chamber 11 and the second chamber 12.

In one embodiment, the first chamber 11 and the second chamber 12 are hollow rectangular structures. It will be appreciated that the shape of the first chamber 11 and the second chamber 12 may be adapted, for example, to be cylindrical, in connection with different curved products. In one embodiment, the plenum 20 is a booster pump. It is understood that in other embodiments, the pressure increasing member 20 may be replaced with other structures having equivalent functions or effects, and may be replaced with a pressure increasing valve.

The air tank 22 is used for storing the pressurized air source. It will be appreciated that in other embodiments, the air storage tank 22 may be replaced by other equivalent structures such as an air storage cylinder.

Referring to fig. 1, in one embodiment, the gas control system 100 further includes a gas source supply 26. An air supply 26 is connected to the plenum 20 for supplying air to the plenum 20. Wherein, the 'air source' refers to air compressed by an air compressor. Further, the air supply 26 provides a positive pressure air supply to the pressure intensifier 20.

It will be appreciated that the air supply 26 may be an air compressor or other mechanism of equivalent efficacy or function.

Referring to fig. 1, in one embodiment, the gas control system 100 further includes a control member 24. The control member 24 is connected to the air storage tank 22 and connected to the first chamber 11 for controlling whether the air source in the air storage tank 22 flows into the first sealing chamber 111. The control element 24 is arranged to control the opening and closing of the air storage tank 22, and an air source can be input into the accommodating cavity 10 at any time according to requirements.

Preferably, the control member 24 is an on-off valve. The switch valve may be disposed between the gas storage tank 22 and the first chamber 11, or may be disposed on the gas storage tank 22 to control the opening and closing of the gas storage tank 22.

In one embodiment, the on-off valve may be connected to a control mechanism (not shown) for controlling the on-off valve. Alternatively, the on-off valve may be controlled by manual operation.

For example, booster pumps are commonly used to control the pressure within the chamber, where the booster pump is a step-wise raising the chamber pressure. In the process of gradually increasing the pressure inside the cavity, the reaction time is slow, and the preset pressure in the cavity can be reached in a longer time. Wherein, the method needs 20s to 30s and has low efficiency.

In this application, gas control system 100 will carry the positive pressure air supply to pressure intensifying piece 20 earlier and carry out the pressure boost, and the positive pressure air supply after being supercharged is carried to gas holder 22 in to store in gas holder 22. When the positive pressure gas needs to be used, the positive pressure gas source is released through the gas storage tank 22, the pressurized positive pressure gas source can be rapidly released into the sealed cavity, and the conversion of the gas pressure in the accommodating cavity 10 can be realized in a short time. This method requires 0.5s, which saves time. In addition, before the positive pressure air source is delivered to the first chamber 11 through the air storage tank 22, the air in the first sealing cavity 111 and the second sealing cavity 121 may be firstly pumped out through the vacuum pumping part 30, so that the inside of the accommodating cavity 10 is in a negative pressure state. At this time, a positive pressure air source is delivered into the first seal cavity 111 through the air storage tank 22, so that an air pressure difference is rapidly formed between the first seal cavity 111 and the second seal cavity 121.

Wherein the amount of pressure in the first chamber 11 may be controlled by adjusting the amount of pressure in the plenum 20. For example, when the control member 24 is closed, the pressure in the first chamber 11 is P0. When the control member 24 is open, the pressure in the first chamber 11 is P2. The pressure of the plenum 20 is P1. The volume of the reservoir 22 is V1 and the volume of the first chamber 11 and the conduit is V2. The final pressure P2= (V1 × P1+ V2 × P0)/(V1 + V2) of the accommodation chamber 10. The pressure in the first chamber 11 can be calculated by the calculation formula, and the pressure in the first chamber 11 can be indirectly controlled by the through hole pressurizing member 20.

Referring to fig. 1, the vacuum unit 30 includes a vacuum member 31 and a conducting member 32. The evacuation member 31 is connected to the second sealing chamber 121, and the conducting member 32 is connected to the first sealing chamber 111 and the evacuation member 31. Wherein, the vacuum-pumping member 31 and the conducting member 32, and the first chamber 11 and the second chamber 12 are connected through an air tube. Further, the vacuum-pumping member 31 is a vacuum pump, and the conducting member 32 is a conducting valve.

When the first sealing cavity 111 and the second sealing cavity 121 need to be simultaneously vacuumized, the vacuuming piece 31 and the conducting piece 32 are both in an open state, so that the first sealing cavity 111 and the second sealing cavity 121 are simultaneously vacuumized. At this time, the first and second

hermetic chambers

111 and 121 are in a vacuum equilibrium state. When the vacuumizing member 31 is turned on and the conducting member 32 is turned off, the first sealing chamber 111 is no longer vacuumized, and the second sealing chamber 121 continues to be vacuumized. When the evacuation member 31 and the conduction member 32 are both in the closed state, the first seal chamber 111 and the second seal chamber 121 are no longer subjected to the evacuation process.

The first chamber 11 and the second chamber 12 contain a large volume of air before the film is applied to the curved product. In the process of attaching, air exists between the curved surface product and the membrane, and air bubbles are easily formed between the curved surface product and the membrane after attaching. After the first chamber 11 and the second chamber 12 are vacuumized, air in the chambers can be pumped out, so that air in a sealed chamber formed between the first chamber 11 and the second chamber 12 is thin, and the condition of bubbles on a curved surface product in the attaching process is improved. In addition, when the second sealing chamber 121 is separately vacuumized, a pressure difference is formed between the first sealing chamber 111 and the second sealing chamber 121. When the storage mechanism is further combined to release the pressurized air pressure into the first sealed cavity 111, the pressure difference value between the first sealed cavity 111 and the second sealed cavity 121 is further increased, and the pressure difference value forms pressure to drive the membrane 300 to be attached to the curved surface product.

Referring to fig. 2, in one embodiment, the gas control system 100 further includes a fixing unit 40. The fixing unit 40 is disposed on the accommodating cavity 10, and further, the fixing unit 40 is disposed on the first chamber 11 and/or the second chamber 12 for fixing the membrane 300.

In one embodiment, the fixing unit 40 includes a suction member 41. The adsorbing member 41 is disposed on an end surface of the second chamber 12 to adsorb a diaphragm (not shown). Wherein the adsorbing member 41 is disposed on an end surface of the second chamber 12 facing the first chamber 11, and the adsorbing member 41 is circumferentially disposed around the second chamber 12.

Preferably, the adsorption member 41 is an adsorption hole. The adsorption holes are provided on the end face of the second chamber 12, and when the diaphragm is provided on the second chamber 12, the diaphragm is fixed at the adsorption hole positions. The adsorption holes are arranged along the circumferential direction of the second cavity 12, so that the adsorption area of the second cavity 12 is increased, and the membrane is better adsorbed.

It will be appreciated that in other embodiments, the suction member 41 may also be provided on the end face of the first chamber 11. Wherein the adsorbing member 41 is disposed on an end surface of the first chamber 11 facing the second chamber 12, and the adsorbing member 41 is circumferentially disposed around the first chamber 11. Further, the suction member 41 is a suction hole. The adsorption holes are arranged on the first chamber 11, and can also play a role in fixing the membrane.

Referring to fig. 2 and 3, the fixing unit 40 includes an adsorbing member 41 for adsorbing the membrane (not shown) and a pressing member 42 for pressing the membrane. The adsorbing member 41 is disposed on the end surface of the first chamber 11 facing the second chamber 12, the pressing member 42 is disposed on the end surface of the second chamber 12 facing the first chamber 11, and the adsorbing member 41 and the pressing member 42 are disposed oppositely. Alternatively, the adsorbing member 41 is disposed on the end surface of the second chamber 12 facing the first chamber 11, and the pressing member 42 is disposed on the end surface of the first chamber 11 facing the second chamber 12.

Wherein, the adsorption member 41 is an adsorption hole, and the adsorption hole is circumferentially arranged along the first chamber 11 or the second chamber 12. The pressing member 42 is a ram made of rubber, and is also disposed circumferentially along the first chamber 11 or the second chamber 12. Further, when the first chamber 11 or the second chamber 12 has a rectangular structure, the ram also has a rectangular structure. When the adsorbing member 41 adsorbs the diaphragm, the edge of the diaphragm is pressed by the pressing member 42, and when the diaphragm is reinforced, the rubber pressing member 42 can seal the connection position of the first chamber 11 and the second chamber 12, so that the air pressure leakage is improved.

It will be appreciated that in other embodiments, the suction member 41 may be replaced by other structures capable of fixing the diaphragm. For example, the suction member 41 may be replaced with a fixed post, and a through hole may be provided at a corresponding position of the diaphragm in order to be able to be engaged with the fixed post.

In the process of fixing the diaphragm by the fixing unit 40, after the diaphragm is disposed on the first chamber 11 and/or the second chamber 12, the diaphragm may divide the sealed chamber formed by the first chamber 11 and the second chamber 12 into a first sealed chamber 111 and a second sealed chamber 121. At this time, if the air pressure in the air container 22 is released, the air pressure exists mainly in the first seal chamber 111, so that a pressure difference is formed between the first seal chamber 111 and the second seal chamber 121. The membrane can be driven to be attached to the curved product in the second sealed cavity 121 under the pressure difference. The curved surface product is placed in second sealed chamber 121, and in-process with the diaphragm laminating on the curved surface product, the pressure that each position point of curved surface product received is balanced stable to and the pressure that each position point of diaphragm received is balanced stable, and the in-process curved surface product of laminating still can support through supporting component (not shown) structure, so that the difficult circumstances such as bubble that appear in the position of the contact point of laminating between the two.
