[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs, the terminology used in the description herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application, the use of the terms "and / or" herein is intended to include any and all combinations of one or more of the associated listed items.

[0036] The embodiment of the present application provides a high-transmittance OCA optical adhesive preparation device, and a high-transmittance OCA optical adhesive preparation device schematic diagram is shown in the figure. Figures 1-4 The high-transmittance OCA optical adhesive preparation device comprises a preparation tank 1, and a feeding mechanism 2 is connected to the upper surface of the tank body of the preparation tank 1, and the output end of the feeding mechanism 2 is connected with a stirring mechanism 3.

[0037] The feeding mechanism 2 comprises a first feeding pipe 21 which is inserted into the top end of the tank body of the preparation tank 1, and a multi-pipe head 22 which is connected to the top end of the first feeding pipe 21.

[0038] The stirring mechanism 3 comprises a stirring shaft 31 which is rotationally connected with the multi-pipe head 22, an L-shaped material pipe 32 which is externally connected to the top end of the shaft body of the stirring shaft 31, and the top end of the L-shaped material pipe 32 is inserted into the pipe body of the first feeding pipe 21.

[0039] The upper surface of the body of the preparation tank 1 is connected with an electric push rod 11, the execution end of the electric push rod 11 extends into the body of the preparation tank 1 and is connected with a lifting disc 12, the disc body of the lifting disc 12 is in sliding connection with the outer surface of the first feeding pipe 21, and the lower surface of the disc body of the lifting disc 12 is connected with a plurality of ultraviolet lamps 13.

[0040] It should be noted that in the present embodiment, the high-transmittance OCA optical adhesive preparation device, the raw materials enter the first feeding pipe 21 through the multi-tube head 22 of the feeding mechanism 2, and then are transported to the stirring mechanism 3. The stirring shaft 31 rotates at the multi-tube head 22, and the L-shaped material pipe 32 guides the raw materials from the first feeding pipe 21 to the vicinity of the stirring shaft 31, and the stirring shaft 31 rotates to stir and mix the raw materials. The electric push rod 11 drives the lifting disc 12 to rise and fall in the preparation tank 1, so that the multiple ultraviolet lamps 13 on the lower surface of the lifting disc 12 can irradiate the mixed materials at different heights. The lifting disc 12 is in sliding connection with the first feeding pipe 21, which ensures the stability of the lifting process.

[0041] The multi-tube head 22 is designed to realize simultaneous feeding of multiple raw materials, improving the feeding efficiency; the stirring mechanism 3 is combined with the feeding structure 2, so that the raw materials can be quickly stirred and mixed after entering, improving the mixing uniformity; the ultraviolet lamps 13 can adjust the height with the lifting disc 12, and for different types of raw materials, the light intensity and irradiation range can be adjusted by changing the height. For example, for raw materials with high sensitivity to ultraviolet light, the ultraviolet lamps 13 can be raised to reduce the light intensity and avoid excessive irradiation affecting their performance; for raw materials that require strong ultraviolet irradiation, the height of the ultraviolet lamps 13 can be lowered to enhance the light effect and ensure sufficient reaction of the raw materials. This flexible adjustment can achieve precise irradiation treatment according to the characteristics of different raw materials, ensuring that each part of the material can be properly irradiated, which is beneficial to improve the transmittance of OCA optical adhesive, and the overall structure is compact, and the components work together to improve the preparation effect.

[0042] Optionally, please refer to the attached Figure 2 The outer surface of the stirring shaft 31 is connected with a plurality of stirring blades 311 arranged from top to bottom.

[0043] In the present embodiment, the plurality of stirring blades 311 on the outer surface of the stirring shaft 31 are arranged from top to bottom, and the stirring blades 311 on the same horizontal plane are symmetrically distributed on the shaft body of the stirring shaft 31. When the stirring shaft 31 rotates, these stirring blades 311 rotate with it, stirring the materials at different heights in the preparation tank 1. The symmetrically arranged stirring blades 311 can form balanced stirring force when rotating, so that the materials are uniformly stressed in the horizontal direction.

[0044] Optionally, please refer to the attached Figure 2 The end of the stirring shaft 31 extending into the first feeding pipe 21 is externally connected with a spiral mixing blade 312.

[0045] In the embodiment, the end of the stirring shaft 31 extending to the outside of the first feeding pipe 21 is connected with a spiral mixing blade 312, which rotates synchronously when the stirring shaft 31 rotates. After the raw materials enter the first feeding pipe 21, they are first stirred and mixed by the spiral mixing blade 312, and then enter the preparation tank 1 through the L-shaped material pipe 32 and the first feeding pipe 21. The spiral mixing blade 312 preliminarily mixes the raw materials before they enter the preparation tank 1, breaks the stratification of the raw materials in advance, and reduces the working pressure of the subsequent stirring mechanism 3; after preliminary mixing, the raw materials can be more quickly mixed with other materials when they enter the preparation tank 1, improving the overall mixing efficiency and uniformity, and helping to improve the quality stability of the final product.

[0046] Optionally, please refer to the attached Figure 2 and 4 The plurality of feeding ends of the multi-tube head 22 are connected with the second feeding pipes 23, and the pipe bodies of the second feeding pipes 23 are connected with the valves 24.

[0047] In the embodiment, the second feeding pipes 23 connected to the plurality of feeding ends of the multi-tube head 22 can respectively access different raw materials, and by controlling the valves 24 on the second feeding pipes 23, the feeding amount and feeding timing of each raw material can be adjusted. When the valve 24 is closed, the corresponding raw material is blocked from being transported, and when the valve 24 is opened, the raw material is allowed to enter the multi-tube head 22 through the second feeding pipe 23. The arrangement of the valve 24 realizes precise control of the feeding of different raw materials, can flexibly adjust the proportion of each raw material according to the preparation requirements, ensures the accuracy of the raw material ratio, and at the same time can avoid leakage of the raw materials when they are not needed to be fed, reduces the waste of raw materials, improves the controllability of the preparation process, and is conducive to stabilizing the performance of the OCA optical adhesive.

[0048] Optionally, please refer to the attached Figure 1 and 2 The feeding mechanism 2 further includes a dustproof box 25 connected to the upper surface of the tank body of the preparation tank 1, the upper surface of the box body of the dustproof box 25 is connected with a motor 26, and the output shaft of the motor 26 is connected with the shaft body of the stirring shaft 31.

[0049] In the embodiment, the dustproof box 25 is installed on the upper surface of the preparation tank 1, covering the connection part of the multi-tube head 22 and the stirring shaft 31 and other structures, reducing the entry of external dust into the inside of the device. The motor 26 is fixed on the upper surface of the dustproof box 25, and the output shaft thereof is connected with the stirring shaft 31, providing power for the rotation of the stirring shaft 31 and driving the stirring shaft 31 and related components to rotate stably.

[0050] Optionally, please refer to the attached Figure 2 The end of the L-shaped material pipe 32 away from the first feeding pipe 21 is rotatably connected with a guide vane 321, and the blade body of the guide vane 321 is provided with a guide groove 322.

[0051] In this embodiment, a guide vane 321 rotatably connected to the end of the L-shaped material tube 32 away from the first feed tube 21 is provided with a guide groove 322. When the raw material flows out of the L-shaped material tube 32, it impacts the guide vane 321, causing it to rotate. At the same time, the guide groove 322 guides the raw material to flow in a specific direction. Under the action of the guide vane 321, the raw material is more evenly dispersed into the material in the preparation tank 1. The rotation of the guide vane 321 and the guiding effect of the guide groove 322 enable the raw material flowing out of the L-shaped material tube 32 to diffuse more evenly into the preparation tank 1, avoiding the raw material from concentrating in a certain area and causing insufficient mixing. This dispersion method enhances the contact area between the raw material and the existing material, speeds up the mixing speed, improves the mixing effect, and helps to ensure the uniformity of the OCA optical adhesive performance.

[0052] Optional, please refer to the appendix Figure 2 and 4 The outer surface of the L-shaped material tube 32 is connected to auxiliary dispersing blades 313, which are symmetrically arranged on the outside of the L-shaped material tube 32.

[0053] In this embodiment, symmetrically arranged auxiliary dispersing blades 313 are connected to the outer surface of the L-shaped material tube 32. When the stirring shaft 31 rotates, the L-shaped material tube 32 rotates accordingly, driving the auxiliary dispersing blades 313 to rotate. During rotation, the auxiliary dispersing blades 313 will beat and disperse any lumps or agglomerates that may appear in the preparation tank 1. The auxiliary dispersing blades 313 can effectively handle the agglomeration and aggregation of materials, breaking them down into small particles or a dispersed state, ensuring that the materials maintain good dispersion during the stirring process, and avoiding the impact of material aggregation on the mixing uniformity and the subsequent irradiation effect of the ultraviolet lamp 13.

[0054] Optional, please refer to the appendix Figure 2 The ultraviolet lamp 13 is tilted, and a support platform 14 is connected to one side surface of the ultraviolet lamp 13. The top of the support platform 14 is connected to the lower surface of the lifting plate 12.

[0055] In this embodiment, the ultraviolet lamp 13 is inclinedly disposed on the lower surface of the lifting plate 12, and one side of its surface is connected to the lifting plate 12 via a support platform 14. The support platform 14 ensures that the tilt angle of the ultraviolet lamp 13 is stable. When the lifting plate 12 is raised and lowered by the electric push rod 11, the inclined ultraviolet lamp 13 can irradiate the material in the preparation tank 1 from different angles, thus expanding the irradiation range.

[0056] Based on the same inventive concept, this embodiment also provides a method for preparing high-transmittance OCA optical adhesive, including the following steps:

[0057] Step one: multiple raw materials are respectively connected to the second feeding pipe 23 through different feeding ends of the multi-tube head 22, the valve 24 corresponding to the second feeding pipe 23 is opened, and the raw materials enter the first feeding pipe 21 through the multi-tube head 22;

[0058] Step two: the raw materials flow through the stirring shaft 31 extending to the spiral mixing blade 312 at one end inside the first feeding pipe 21, and the stirring shaft 31 rotates to drive the spiral mixing blade 312 to preliminarily mix the raw materials;

[0059] Step three: the preliminarily mixed raw materials are guided into the preparation tank 1 through the L-shaped pipe 32, the motor 26 drives the stirring shaft 31 to rotate, drives the stirring blade 311 and the auxiliary beating blade 313 to rotate, and fully stirs and mixes the raw materials, and the guide vane 321 at the end of the L-shaped pipe 32 rotates under the impact of the raw materials, and cooperates with the guide groove 322 to uniformly disperse the raw materials;

[0060] Step four: the electric push rod 11 is started to drive the lifting disc 12 to ascend and descend, the height of the ultraviolet lamp 13 is adjusted, the irradiation intensity and range of the ultraviolet lamp 13 are controlled according to the sensitivity of the raw materials to ultraviolet rays, and the mixed materials are irradiated and treated;

[0061] Step five: after stirring, mixing and ultraviolet irradiation treatment, high-transmittance OCA optical glue is obtained.

[0062] Based on the same inventive concept, the embodiment also provides that in step four, when the raw materials have high sensitivity to ultraviolet rays, the lifting disc 12 is raised by the electric push rod 11 to make the ultraviolet lamp 13 away from the materials to weaken the light intensity; when the raw materials need strong ultraviolet irradiation, the lifting disc 12 is lowered to make the ultraviolet lamp 13 close to the materials to enhance the light intensity.

[0063] The above describes the present application with reference to the drawings, and it is obvious that the specific implementation of the present application is not limited to the above manner, as long as the method concept and technical scheme of the present application are adopted for such non-essential improvement, or the concept and technical scheme of the present application are directly applied to other occasions without improvement, which are all within the protection scope of the present application.
