The supporting mechanism 40 is disposed in the second cavity 30 for carrying the product 200 having a curved surface. The heating mechanism 60 is disposed in the first chamber 20 for heating the flexible substrate 300.
Referring to fig. 1 and 2, in one embodiment, the bonding apparatus 100 further includes a vacuum pumping mechanism 70. The vacuum pumping mechanism 70 is connected to the first chamber 20 and the second chamber 30, and is used for pumping vacuum to the first chamber 20 and the second chamber 30. Before the flexible substrate (not shown) is attached to the product (not shown), the interior of the first cavity 20 and the interior of the second cavity 30 are vacuumized, so as to improve the condition that air bubbles exist between the flexible substrate and the product during the attaching process.

In one embodiment, the flexible substrate 300 includes, but is not limited to, a protective film, a process film, a polarizer, and the like. The product 200 includes but is not limited to curved products such as spectacle lenses, curved cover plates, camera lenses, etc.
Fig. 3 shows a schematic connection diagram of a part of the mechanism in the attaching apparatus 100. Fig. 3 shows the connection of the storage mechanism 10, the first cavity 20, and the second cavity 30.
Referring to fig. 3, the storage mechanism 10 is used for storing the pressurized gas and providing the pressurized gas pressure into the first cavity 20, so that a gas pressure difference can be formed between the inside of the first cavity 20 and the inside of the second cavity 30. The air pressure difference is used to apply an external force to the flexible substrate 300, so that the flexible substrate 300 is attached to the curved surface of the product.
The reservoir mechanism 10 includes a gas source 11, a pressurizing member 12, and a reservoir tank 13. The pressurizing part 12 is connected to the gas source 11 and the storage tank 13 respectively, and is used for conveying other pressurized gas in the gas source 11 to the storage tank 13 for storage. Wherein, the pressurizing piece 12 is connected with the air source 11 and the storage tank 13 through air pipes. The gas source 11 is used for outputting positive pressure gas, and the positive pressure gas flows to the storage tank 13 for storage after being pressurized by the pressurizing member 12.
In one embodiment, the plenum 12 is a booster pump. It is understood that in other embodiments, the pressure increasing member 12 may be replaced with other structures having equivalent functions or effects, and may be replaced with a pressure increasing valve.
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 this method requires a time of 20s to 30 s.
The reservoir mechanism 10 first pressurizes the positive pressure gas and stores the positive pressure gas in the reservoir tank 13. When the positive pressure gas is required to be used, the conversion of the gas pressure can be achieved in a short time by releasing the positive pressure gas from the storage tank 13. Namely, the pressurized positive pressure gas can be rapidly released into the first cavity 20, which takes 0.5s. By storing the pressurized air pressure in the storage tank 13, the bonding efficiency of the flexible substrate 300 can be improved.
Referring to fig. 3, the first chamber 20 is connected to the storage tank 13 through an air pipe. The first chamber 20 is hollow and has an opening on a side facing the second chamber 30.
Referring to fig. 3, the second cavity 30 is hollow and has an opening on a side facing the first cavity 20. The first cavity 20 and the second cavity 30 are adapted in contour so that the first cavity 20 and the second cavity 30 can form a whole structure with a sealed cavity A after being closed. A flexible substrate is disposed at the connection location of the first and second cavities 20 and 30.
In one embodiment, the first and second cavities 20 and 30 are hollow rectangular structures. It will be appreciated that the shape of the first and second cavities 20, 30 may be adjusted, for example, arranged in a cylindrical shape, in connection with different products.
Fig. 4 is a schematic cross-sectional view of the bonding apparatus 100, in which the supporting mechanism 40 and the flexible substrate 300 are disposed in the first cavity 20 and the second cavity 30, and the product 200 is disposed on the supporting mechanism 40.
Referring to fig. 4, the supporting mechanism 40 is disposed in the second chamber 30. The supporting mechanism 40 includes a supporting fixture 41 and a driving member 42, the driving member 42 is connected to the supporting fixture 41 for driving the supporting fixture 41 to move, and the supporting fixture 41 is used for placing the product 200. Wherein the driving member 42 is installed on the bottom wall of the second cavity 30, and the supporting fixture 41 is installed on the driving member 42.
The supporting fixture 41 is used to place the product 200 near the end of the first cavity 20, and the supporting fixture 41 is a profiling structure to more stably support the product 200.
In one embodiment, the driver 42 is a drive cylinder. The driving cylinder is used for driving the supporting fixture 41 to move towards the direction close to the first cavity 20. By providing the driving member 42 on the supporting jig 41, the supporting mechanism 40 has a height-adjustable function. The height-adjustable supporting mechanism 40 can adapt to the deformation and position of the flexible substrate 300, for example, since the flexible substrate 300 has a certain ductility after being heated, in order to make the flexible substrate 300 fit on the product 200, the driving member 42 can drive the supporting fixture 41 to move toward the direction close to the flexible substrate 300, so that the product 200 and the flexible substrate 300 can fit conveniently.
It will be appreciated that in other embodiments, the drive member 42 may also be a motor or other structure having equivalent efficacy or function.
