[0024] Referring to Figure 1 and Figure 2 , the present application provides a preparation system 10 of liquid crystal display film. The preparation system 10 provided by the present application realizes the preparation of the liquid crystal display film 300a by combining the sealing process and the cutting process, so as to avoid the technical problems such as burn, carbonization damage and a large amount of smoke which are prone to occur at the edge of the liquid crystal display film 300a in the laser cutting process adopted by the prior art for preparing the liquid crystal display film 300a, and pose a threat to the environment and the health of the operating personnel.

[0025] The preparation system 10 in the present application includes a conveying device 1, a sealing device 2 and a cutting device 3. The conveying device 1 is provided with an inlet 11 and an outlet 12. The conveying device 1 is used to convey the first display film 10a and the second display film 10b from the inlet 11 to the outlet 12. The sealing device 2 is used to perform the sealing process on the first display film 10a and the second display film 10b to form a liquid crystal display film area 300. The cutting device 3 is used to perform the cutting process on the liquid crystal display film area 300 to form an independent liquid crystal display film 300a. The first display film 10a and the second display film 10b are arranged oppositely, and there is a spacing between the first display film 10a and the second display film 10b to form an injection space 10c. The injection space 10c is used for the preparation system 10 to inject a specific material between the first display film 10a and the second display film 10b to complete the preparation of display films of different materials.

[0026] In the present embodiment, the conveying device 1 can be a device with several transmission mechanisms (such as transmission belts). The inlet 11 can be used by the user to prearrange the first display film 10a and the second display film 10b to be arranged oppositely and have a spacing, or the transmission mechanism can automatically arrange the first display film 10a and the second display film 10b to be arranged oppositely and have a spacing. The first display film 10a and the second display film 10b can be transported in the conveying direction X in parallel by different transmission mechanisms. For example, the different transmission mechanisms all move along the same conveying direction X, and the different transmission mechanisms have a spacing in the vertical direction, so as to transport the first display film 10a and the second display film 10b by the different transmission mechanisms respectively and form the injection space 10c.

[0027] Please refer to Figure 3 , which is a schematic view of a sealing equipment provided by an embodiment of the present application for forming liquid crystal display film regions. The sealing equipment 2 is located between the feeding port 11 and the discharging port 12, and stores adhesive material and liquid crystal material. The sealing equipment 2 is used to inject the adhesive material and the liquid crystal material into the injection space 10c to form a plurality of adhesive regions 100 and a plurality of liquid crystal regions 200, so as to bond the first display film 10a and the second display film 10b and form a plurality of liquid crystal display film regions 300 in the injection space 10c. Specifically, the sealing equipment 2 comprises a plurality of sealing devices 21. The plurality of sealing devices 21 are arranged side by side along the conveying direction X of the conveying equipment 1. Each sealing device 21 stores adhesive material and liquid crystal material.

[0028] As shown in Figure 5 , each sealing device 21 comprises a first adhesive container 211 and a second adhesive container 212 for storing adhesive material, and a liquid crystal container 213 for storing liquid crystal material. The liquid crystal container 213 is arranged between the first adhesive container 211 and the second adhesive container 212. In the present application, the adhesive material can be glue, and the liquid crystal material can be liquid crystal. The liquid crystal container 213, the first adhesive container 211 and the second adhesive container 212 can be droppers for storing different materials. In the present application, the different containers of each sealing device 21 can respectively cause the corresponding stored material to drip and be injected into the injection space 10c.

[0029] As shown in Figure 4 , and Figure 6- Figure 7 , each liquid crystal display film region 300 comprises one liquid crystal region 200 and an adhesive region 100 surrounding the corresponding liquid crystal region 200. Specifically, each adhesive region 100 comprises a plurality of first sealing edges 100a and a plurality of second sealing edges 100b connected in sequence. The plurality of first sealing edges 100a and the plurality of second sealing edges 100b are formed by the first adhesive container 211 and the second adhesive container 212 injecting the injection space 10c, respectively. In the present application, the adhesive region 100 is a closed region surrounded by the plurality of first sealing edges 100a and the plurality of second sealing edges 100b connected in sequence, so as to ensure that the liquid crystal material in the corresponding liquid crystal region 200 surrounded thereby does not leak out when being cut by the cutting equipment 3, thereby reducing the damage of the liquid crystal display film 300a.

[0030] In the present embodiment, the sealing devices 21 form a plurality of sealing areas between the feeding port 11 and the cutting device 3. Each sealing area includes a portion of the liquid crystal display film area 300. The sealing device 2 can be driven to move in the plurality of sealing areas to ensure that the adhesive material and the liquid crystal material can be accurately injected into the injection space 10c. Specifically, the sealing device 2 is provided with a driving assembly 20. The driving assembly 20 is used to drive the sealing device 2 to move between the feeding port 11 and the cutting device 3 to inject the adhesive material and the liquid crystal material into the injection space 10c. The driving assembly 20 includes a plurality of driving devices, each corresponding to a sealing device 21, for driving the corresponding sealing device 21 to move.

[0031] Further, the driving device can include a clamping device 20a for clamping the corresponding sealing device 21, and a control device 20b for controlling the clamping device 20a to operate. The control device 20b can be used by the user to control the clamping device 20a to perform corresponding operations, such as controlling the clamping device 20a to move in the sealing area, controlling the clamping device 20a to clamp the corresponding sealing device 21 to complete the pipette operation at a specific position in the sealing area, etc. Accordingly, the liquid crystal container 213, the first adhesive container 211 and the second adhesive container 212 can simultaneously inject the corresponding stored materials into the injection space 10c. In other embodiments, the liquid crystal container 213, the first adhesive container 211 and the second adhesive container 212 can sequentially inject the corresponding stored materials into the injection space 10c in a specific order.

[0032] It can be understood that the driving device can also be directly connected to the corresponding sealing device 21, as long as it can drive the sealing device 21 to move in the plurality of sealing areas. Preferably, each sealing area represents the range in which the sealing device 21 can move. The corresponding driving device can only drive the corresponding sealing device 21 to move in the corresponding sealing area.

[0033] Please refer to Figure 8 which is a schematic view of the cutting device cutting the liquid crystal display film area according to the present embodiment. The cutting device 3 is located between the sealing device 2 and the discharge port 12, and includes a die 31 and a cutter 32. The die 31 is provided with a plurality of cavities 311. Each cavity 311 corresponds to a liquid crystal display film area 300 of a predetermined shape. The cutter 32 is used to cut the liquid crystal display film area 300 in each cavity 311 to obtain a plurality of liquid crystal display films 300a. The plurality of liquid crystal display films 300a are transported to the discharge port 12 by the transportation device 1. The predetermined shape is the shape of the corresponding liquid crystal area 200. The shape of the corresponding liquid crystal area 200 is adjusted by adjusting the distance between the first adhesive container 211 and the second adhesive container 212 in the corresponding sealing device 21, so as to adjust the adhesive area 100, and further adjust the liquid crystal area 200 surrounded thereby.

[0034] Further, the shape of all the liquid crystal regions 200 in the same sealing region is the same, so that all the liquid crystal display film regions 300 in the same sealing region are transported to the corresponding acupoints 311 for being cut by the cutter 32 to obtain the partial liquid crystal display films 300a with the same shape.

[0035] Further, the cutter 32 is used to cut the partial adhesive regions 100 of each liquid crystal display film region 300, so that each liquid crystal display film 300a is surrounded by the cut partial adhesive regions 100. The thickness of the cut partial adhesive regions 100 is less than the thickness of the first sealing edge 100a and the second sealing edge 100b, so as to ensure that the obtained liquid crystal display film 300a does not leak liquid crystal material.

The specific features of the preparation system 10 of the liquid crystal display film have been described in detail above. The preparation method includes steps S101-S104.

[0037] In step S101, the first display film 10a and the second display film 10b are arranged oppositely with a spacing therebetween to form an injection space 10c.

[0038] In step S101, the first display film 10a and the second display film 10b are arranged oppositely with a spacing therebetween to form an injection space 10c. The injection space 10c is used for the preparation system 10 to inject a specific material between the first display film 10a and the second display film 10b to complete the preparation of the display film with different materials.
