Description

A jig for manufacturing display screen module and its using method Technical Field

[0001] The present application relates to the field of LED display screens, and in particular to an LED display screen. Background Art

[0002] With the continuous advancement of technology, display modules are playing an increasingly important role in electronic products. Producing high-quality display modules requires a series of specially designed processes and equipment. Among these, jigs used in display module production, as one of the key production tools, play a crucial role.

[0003] This type of jig is typically used to cure and process key components in display modules, ensuring stable performance and high quality. The design and use of the jig directly impacts the production efficiency and quality of the finished product. Therefore, jigs manufactured for display modules require precise structures and reliable processes to meet growing market demands.

[0004] The existing method for manufacturing a display screen is a four-sided curved display screen bonding process disclosed in application number 202011428757.2. This technology discloses "including attaching the two sides of the bonding glue to the flexible panel and the protective panel respectively to form a body to be cured, placing the body to be cured on a contoured jig with air holes, and blowing air to the body to be cured through the air holes during vacuum hot pressing to cure the body to be cured. In this application, before vacuum hot pressing, the body to be cured is placed on a contoured jig, and the bonding glue is converted into a molten state during vacuum hot pressing. By blowing air to the body to be cured, the flow of the bonding glue in the body to be cured is accelerated, so that the bonding glue fully fills the gap between the flexible panel and the protective panel, and fills all areas in the body to be cured."

[0005] Another example is the bonding process for small and medium-sized flat-panel display screens disclosed in application number 202011560359.6. This technology discloses "including attaching a display panel and a protective panel on both sides of a hot-melt optical adhesive film, cold pressing to form a body to be cured, pressurizing and degassing the body to be cured, and curing the body to be cured. The display screen bonding process in the embodiment of the present application is suitable for small and medium-sized flat-panel display screens. During the bonding process of the display screen, both the cold pressing and pressurizing and degassing steps can adopt a fast pressing method, without the need for heating, and the production time is greatly shortened. The hot-melt optical adhesive film will not be deformed due to heating, causing the film to rebound and affecting the bonding quality of the display screen."

[0006] In the above solution, the display screen manufacturing method used is difficult to ensure the accuracy and stability during the module bonding process, and its curing effect is poor and the efficiency is low.

[0036] Example 1

[0037] Referring to Figure 1, a jig for manufacturing a display screen module includes an upper jig 1, a lower jig 2 that is sealed to the edge of the upper jig 1, a receiving chamber 3 formed between the sealed upper jig 1 and the lower jig 2, a pneumatic rod installed on the upper jig 1 to drive the upper jig 1 to move, a module placement plate 4 arranged in the receiving chamber 3, and a module light board 5 installed on the upper jig 1. The bottom surface of the lower jig 2 is a transparent part 6 that can pass ultraviolet radiation, and a bottom sealed connection is formed between the transparent part 6 and the lower jig 2.

[0038] The upper jig 1 and the lower jig 2 are tightly connected by a fitting seal to form a accommodating chamber 3. This design can effectively prevent the glue from overflowing and ensure a clean and tidy fitting process; efficient pneumatic rod drive: The pneumatic rod installed on the upper jig 1 can accurately move and control the upper jig 1, improving the convenience and efficiency of operation; the bottom surface of the lower jig 2 adopts a transparent part 6 that can pass through ultraviolet radiation, and forms a bottom sealing connection with the lower jig 2 to ensure that the glue will not leak out, and it is also conducive to uniform ultraviolet radiation.

[0039] The upper fixture 1 and the lower fixture 2 need to have the required shape and size, and be able to fit tightly and seal. The module placement plate 4 is installed in the accommodating chamber 3, and the position of the module can be flexibly adjusted and arranged as needed.

[0040] A pneumatic rod is installed on the upper jig 1 to ensure that the upper jig 1 can be accurately moved and controlled. A module light board 5 is installed on the upper jig 1 to provide backlighting. A transparent part 6 that can pass through ultraviolet radiation is installed on the bottom surface of the lower jig 2 to form a bottom sealed connection with the lower jig 2.

[0041] Place the display screen module to be bonded in the jig. By moving the upper jig 1 and controlling the pneumatic rod, the module is tightly bonded to the upper jig 1, the lower jig 2 and the module placement plate 4. After bonding is completed, use ultraviolet light to cure the glue.

[0042] The transparent member 6 is a glass plate. Modified polyurethane 7 capable of submerging the module light board 5 is injected above the transparent member 6 . An ultraviolet irradiator is provided below the transparent member 6 .

[0043] The transparent glass plate allows ultraviolet rays to irradiate the module glue from below, ensuring sufficient ultraviolet radiation, which is conducive to curing the glue on the module light board 5. And because the ultraviolet irradiator is located below the transparent part 6, it can irradiate the entire module more evenly. The modified polyurethane 7 can be used as a glue, filled between the glass plate and the module light board 5, which helps to fix the position of the module light board 5 and improve the sealing. At the same time, it can also reduce the amount of glue used and improve the curing efficiency.

[0044] Select a glass plate of appropriate size and thickness, and ensure that the surface is flat and clean, inject the modified polyurethane 7 onto the top of the glass plate to form a uniform layer of glue on the glass plate, and then place the module light board 5 on the modified polyurethane 7 so that it is immersed in the modified polyurethane 7.

[0045] Install an ultraviolet irradiator under the glass plate to ensure that it can evenly irradiate the entire module. Place the module to be treated close to the glass plate so that the modified polyurethane 7 and the module light board 5 are immersed. Start the ultraviolet irradiator as needed to perform ultraviolet curing treatment on the module.

[0046] The upper fixture 1 is provided with a copper column for connecting with the module light board 5. The upper fixture 1 and the module light board 5 are connected by screws passing through the copper column. The upper fixture 1 is also provided with a vacuum hole. The conventional vacuum method is used to prevent bubbles in the glue from affecting the module display effect.

[0047] The connection method of copper columns and screws can ensure a firm connection between the module light board 5 and the upper fixture 1, avoiding displacement or loosening during the bonding process, thereby ensuring the accuracy and consistency of the bonding; through vacuuming, bubbles in the glue can be effectively removed, ensuring the purity and uniformity of the glue when the module is bonded, avoiding the influence of bubbles on the display effect, and improving the bonding quality.

[0048] Copper pillars for connecting with the module light board 5 are pre-set on the upper jig 1 to ensure that they are positioned accurately and can fully fit with the module light board 5; the module light board 5 is placed on the upper jig 1, and the module light board 5 is firmly connected to the upper jig 1 by screws passing through the copper pillars; according to the design requirements, vacuum holes are opened at appropriate positions, and a vacuum pump is connected to vacuum the accommodating chamber 3; the vacuum pump is started to vacuum the accommodating chamber 3 to ensure that the bubbles in the glue are effectively removed. After the vacuuming is completed, the module to be bonded is placed on the upper jig 1. Through bonding under vacuum, the purity and uniformity of the glue are ensured, and the generation of bubbles is avoided.

[0049] A method for using a jig for manufacturing a display module comprises the following steps:

[0050] Inject modified polyurethane 7 into the bottom surface of the lower fixture 2;

[0051] Fix the module light board 5 on the upper fixture 1;

[0052] The upper jig 1 is driven by the pneumatic rod, thereby driving the module light board 5 to approach the lower jig 2 through the upper jig 1, until the front of the module light board 5 is immersed in the modified polyurethane 7, and a fitting seal is formed between the upper jig 1 and the lower jig 2;

[0053] Ultraviolet light is used to illuminate the accommodating chamber 3 through the transparent member 6 for preliminary curing;

[0054] The module light board 5 that has been illuminated is moved out of the accommodating chamber 3 through the upper fixture 1 and sent into an oven for secondary curing to complete the sealing process of the electronic components on the module light board 5.

[0055] After forming a seal between the upper fixture 1 and the lower fixture 2, a vacuum operation is performed through the vacuum hole.

[0056] Through the structural design of the upper jig 1 and the lower jig 2, and the drive of the pneumatic rod, the module light board 5 can be precisely fitted to ensure the accuracy and consistency of the fit. By injecting modified polyurethane 7 from the bottom and immersing the module light board 5 therein, a sealed accommodating chamber 3 can be formed to protect the electronic components in the module from the influence of the external environment, thereby improving the reliability and durability of the module.

[0057] By irradiating the transparent part 6 with ultraviolet light for preliminary curing, the modified polyurethane 7 can be quickly cured, thereby improving production efficiency and process stability. The module light board 5 that has undergone preliminary curing is sent to the oven for secondary curing treatment to ensure that the glue is thoroughly cured, further enhancing the quality and reliability of the module.

[0058] The method of using ultraviolet rays to illuminate the accommodating chamber 3 through the transparent member 6 is as follows:

[0059] The ultraviolet irradiator under the transparent member 6 is turned on to irradiate the lower module position, thereby irradiating the module light board 5 immersed in the modified polyurethane 7 for 10-20 seconds.

[0060] Ultraviolet rays have the characteristic of rapid curing. Irradiating the module light board 5 immersed in the modified polyurethane 7 for 10-20 seconds can quickly achieve preliminary curing, thereby improving production efficiency. No heating is required during the ultraviolet curing process, so compared with traditional thermal curing methods, it can save energy and reduce the impact on the environment. Through rapid curing, the surface of the module light board 5 can be cured in a shorter time.

[0061] The method of sending the illuminated module light board 5 into the oven for secondary curing is as follows:

[0062] The module light board 5 is baked at a temperature range of 80 to 95° C. for 10 to 12 minutes until the glue is completely dry.

[0063] Assemble the sealed mold lamp panel and the lamp bottom shell.

[0064] Secondary curing in an oven ensures the glue is completely dry. This improves the sealing and stability of the module light board 5, ensuring effective protection of electronic components and long-term reliable operation. The oven provides precise temperature control and can perform curing within a range of 80-95°C, ensuring temperature stability during the curing process. Furthermore, the curing time is 10-12 minutes, which fully ensures the glue is dried and cured.

[0065] Through a unified oven curing process, the impact of human factors in the curing process can be reduced, the stability and consistency of the process can be improved, and thus the quality and reliability of the product can be improved; after the sealing process is completed, the mold lamp panel is assembled with the lamp base shell to ensure the durability and stability of the sealing effect, further improving the quality of the product.

[0067] Referring to Figures 2-3, a jig for manufacturing display screen modules includes an upper jig 1, a lower jig 2 that is sealed to the edge of the upper jig 1, a accommodating chamber 3 formed between the sealed upper jig 1 and the lower jig 2, a pneumatic rod installed on the upper jig 1 to drive the upper jig 1 to move, a module placement plate 4 arranged in the accommodating chamber 3, and a module light board 5 installed on the upper jig 1. The bottom surface of the lower jig 2 is a transparent part 6 that can pass ultraviolet radiation, and a bottom sealed connection is formed between the transparent part 6 and the lower jig 2.

[0068] The upper jig 1 and the lower jig 2 are tightly connected by a fitting seal to form a accommodating chamber 3. This design can effectively prevent the glue from overflowing and ensure a clean and tidy fitting process; efficient pneumatic rod drive: The pneumatic rod installed on the upper jig 1 can accurately move and control the upper jig 1, improving the convenience and efficiency of operation; the bottom surface of the lower jig 2 adopts a transparent part 6 that can pass through ultraviolet radiation, and forms a bottom sealing connection with the lower jig 2 to ensure that the glue will not leak out, and it is also conducive to uniform ultraviolet radiation.

[0069] The upper fixture 1 and the lower fixture 2 need to have the required shape and size, and be able to fit tightly and seal. The module placement plate 4 is installed in the accommodating chamber 3, and the position of the module can be flexibly adjusted and arranged as needed.

[0070] A pneumatic rod is installed on the upper jig 1 to ensure that the upper jig 1 can be accurately moved and controlled. A module light board 5 is installed on the upper jig 1 to provide backlighting. A transparent part 6 that can pass through ultraviolet radiation is installed on the bottom surface of the lower jig 2 to form a bottom sealed connection with the lower jig 2.

[0071] Place the display screen module to be bonded in the jig. By moving the upper jig 1 and controlling the pneumatic rod, the module is tightly bonded to the upper jig 1, the lower jig 2 and the module placement plate 4. After bonding is completed, use ultraviolet light to cure the glue.

[0072] The transparent member 6 is a glass plate. Modified polyurethane 7 capable of submerging the module light board 5 is injected above the transparent member 6 . An ultraviolet irradiator is provided below the transparent member 6 .

[0073] The transparent glass plate allows ultraviolet rays to irradiate the module glue from below, ensuring sufficient ultraviolet radiation, which is conducive to curing the glue on the module light board 5. And because the ultraviolet irradiator is located below the transparent part 6, it can irradiate the entire module more evenly. The modified polyurethane 7 can be used as a glue, filled between the glass plate and the module light board 5, which helps to fix the position of the module light board 5 and improve the sealing. At the same time, it can also reduce the amount of glue used and improve the curing efficiency.

[0074] Select a glass plate of appropriate size and thickness, and ensure that the surface is flat and clean, inject the modified polyurethane 7 onto the top of the glass plate to form a uniform layer of glue on the glass plate, and then place the module light board 5 on the modified polyurethane 7 so that it is immersed in the modified polyurethane 7.

[0075] Install an ultraviolet irradiator under the glass plate to ensure that it can evenly irradiate the entire module. Place the module to be treated close to the glass plate so that the modified polyurethane 7 and the module light board 5 are immersed. Start the ultraviolet irradiator as needed to perform ultraviolet curing treatment on the module.

[0076] The upper jig 1 is provided with a copper column for connecting with the module light board 5. The upper jig 1 and the module light board 5 are connected by screws passing through the copper column. A sealed connection position 8 is also provided between the upper jig 1 and the lower jig 2. A vacuum hole 9 is also provided on the upper jig 1. The sealed connection position 8 includes a lower concave position 81 provided on the lower jig 2, and an upper convex position 82 provided on the upper jig and cooperating with the lower concave position 81, and a sealed channel 83 provided on the lower jig 2 and connected between the two lower concave positions 81. The vacuum hole 9 is provided with two groups, and one group is located on one side of the sealed connection position 8, and the other group is connected to the sealed channel 83. The conventional vacuum method is to prevent bubbles in the glue from affecting the module display effect.

[0077] The connection method of copper columns and screws can ensure a firm connection between the module light board 5 and the upper fixture 1, avoiding displacement or loosening during the bonding process, thereby ensuring the accuracy and consistency of the bonding; through vacuuming, bubbles in the glue can be effectively removed, ensuring the purity and uniformity of the glue when the module is bonded, avoiding the influence of bubbles on the display effect, and improving the bonding quality.

[0078] Copper pillars for connecting with the module light board 5 are pre-set on the upper jig 1 to ensure that they are positioned accurately and can fully fit with the module light board 5; the module light board 5 is placed on the upper jig 1, and the module light board 5 is firmly connected to the upper jig 1 by screws passing through the copper pillars; according to the design requirements, vacuum holes 9 are opened at appropriate positions, and a vacuum pump is connected to vacuum the accommodating chamber 3. The cooperation between the vacuum hole 9 and the sealing connection position 8 can achieve a better vacuum sealing effect; start the vacuum pump and vacuum the accommodating chamber 3 to ensure that the bubbles in the glue are effectively removed. After the vacuuming is completed, the module to be bonded is placed on the upper jig 1. Through bonding under vacuum, the purity and uniformity of the glue are ensured, and the generation of bubbles is avoided.

[0083] Ultraviolet light is used to illuminate the accommodating chamber 3 through the transparent member 6 for preliminary curing;

[0084] The module light board 5 that has been illuminated is moved out of the accommodating chamber 3 through the upper fixture 1 and sent into an oven for secondary curing to complete the sealing process of the electronic components on the module light board 5.
