Description

Technical Field

[0001] The present invention mainly relates to the technical field of display auxiliary processing equipment, and in particular to a universal device and method for laminating LCM screen light-shielding adhesive. Background Art

[0002] During the production of LCM screen modules, high-precision templates and substrates require relatively high alignment accuracy to ensure the accuracy of circuit connections. If light-shielding glue is not used, the glue may be accidentally applied to the circuit, causing a short circuit or other adverse consequences. In addition, light-shielding glue can also protect the glass substrate and other components from damage. During the production process, the LCD module needs to meet certain brightness requirements. Using light-shielding glue can reflect light back, thereby increasing brightness and improving product quality.

[0003] The light shielding glue needs to be attached to the side of the display module and the back of the display module, and the light shielding glue cannot touch the CG board, otherwise it will cause debonding. Pure manual operation requires a lot of time for alignment or a lot of work experience; the existing auxiliary device will be constantly debugged due to processing accuracy issues, and the operation requires a microscope, the device cost, and the design cost are high but the benefits are low. Summary of the invention

[0011] Furthermore, in the present invention, the vertical cross-section of the slide rail is a T-shaped structure.

[0012] Furthermore, in the present invention, a plurality of rows of threaded holes are arranged at equal distances on the base.

[0013] Furthermore, in the present invention, the bonding method used by any of the above-mentioned general devices capable of bonding LCM screen shading adhesive comprises the following steps:

[0014] Step 1: Perform debugging, place and fix the product screen on the product board, and then adjust the positions of the bottom limit block, side limit block, and top limit block, and then expose the display module on the top of the LCM screen to block the CG board;

DETAILED DESCRIPTION

[0028] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings, but the present invention can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the content disclosed in the present invention more thorough and comprehensive.

[0029] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. The terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs. The terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0031] For examples, please refer to the attached Figure 1-4 A universal device and method for laminating LCM screen shading glue, comprising a base 9, a three-axis displacement platform 4 and a slide table 6 are installed on the top of the base 9, a product board 3 is installed on the top of the three-axis displacement platform 4, a slide assembly 8 is installed on the top of the slide table 6, the slide assembly 8 includes a slide bar 10 fixedly connected to the slide table 6 and a slider 11 sliding on the slide bar 10, a shading glue carrier 7 of the slider 11, and two positioning columns 12 are arranged on both sides of the top of the shading glue carrier 7 close to the product board 3.

[0032] It should be noted that the three-axis displacement platform 4 can adopt a three-axis displacement platform of model NT305WM, so that the product and the product plate 3 have three degrees of freedom of translation in three directions.

[0033] For details, please refer to the attached Figure 1 , two side limit blocks 2 are installed on both sides of the top of the product plate 3, and a bottom limit block 1 is installed on the top of the end of the product plate 3 away from the slide rail platform 6;

[0034] Furthermore, two first mounting grooves 14 are provided on the side limit block 2 and the bottom limit block 1, and the side limit block 2 and the bottom limit block 1 are fixedly connected to the product plate 3 by installing fixing bolts in the first mounting grooves 14;

[0035] In this embodiment, it should be noted that both the side limit block 2 and the bottom limit block 1 can limit the LCM screen, and the positions of the side limit block 2 and the bottom limit block 1 can be adjusted to limit the LCM screens of different sizes.

[0036] For details, please refer to the attached Figure 1 and attached Figure 3 A top limit block 5 is installed on the top of the side of one end of the product plate 3 close to the slide rail platform 6, and two second installation grooves 15 are arranged on the top limit block 5. The top limit block 5 is fixedly connected to the product plate 3 by installing fixing bolts in the second installation grooves 15;

[0037] In this embodiment, it should be noted that the top limit block 5 is also used to limit the LCM screen. At the same time, the top limit block 5 is fixed to the side of the product board 3 and can be adjusted up and down. This design is because the height of the top limit block 5 cannot be higher than the thickness of the CG board, otherwise the fitting action will cause interference.

[0038] For details, please refer to the attached Figure 2 The light shielding adhesive carrier 7 is provided with a notch at the bottom of one side close to the product plate 3, a pressing adhesive pad 13 is installed in the middle of the notch of the light shielding adhesive carrier 7, and an outward bevel is provided at the bottom of one side of the outer side of the pressing adhesive pad 13;

[0039] In this embodiment, it should be noted that the positioning column 12 is used to position the light-shielding glue, and the pressing glue pad 13 can press the light-shielding glue more tightly on the side end of the screen when in use.

[0040] For details, please refer to the attached Figure 4 , the vertical section of the slide rail 10 is a T-shaped structure;

[0041] In this embodiment, it should be noted that the slider 11 is stably positioned on the slide rail 10 for sliding, and the slide rail assembly 8 is used to fix the movement direction of the light-shielding adhesive relative to the product, thereby reducing manual laminating actions.

[0042] For details, please refer to the attached Figure 1 , the base 9 is provided with multiple rows of threaded holes at equal distances;

[0043] In this embodiment, it should be noted that the base 9 is mainly used to fix the initial relative position range of the product and the light-shielding adhesive, while the threaded hole is used to achieve a universal effect.

[0044] Furthermore, the bonding method used by any of the above-mentioned general devices capable of bonding LCM screen shading adhesive comprises the following steps:

[0045] Step 1: Perform debugging, place and fix the product screen on the product board 3, then adjust the positions of the bottom limit block 1, the side limit block 2, and the top limit block 5, and then expose the display module on the top of the LCM screen to block the CG board;

[0046] Step 2: Put the positioning hole of the light-shielding glue on the positioning column 12, adjust the relative position of the slider 11 and the top of the product, and then observe the position difference between the light-shielding glue and the light-shielding glue limit line, and adjust the three-axis displacement platform 4 until the position is accurate. After successful calibration, fix the parameters of the three-axis displacement platform 4;

[0047] Step 3: After adjustment, push the slider 11 on the slide rail 10 to allow the light-shielding glue carrier 7 to drive the light-shielding glue to move toward the product on the product plate 3 to complete the light-shielding glue bonding.

[0048] In this embodiment, the existing technology has high precision requirements for the shading glue, and the processing precision does not meet the requirements, so the previous device needs to be manually adjusted on site, and the debugging time is too long, usually about 3 hours, and the debugging time is long;

[0049] At the same time, the wearing of the bonding parts exceeds the precision and needs to be readjusted, which has high maintenance costs. Moreover, it is not universal and needs to be redesigned every time, which has high design and production costs. For all the above reasons, the investment rate of the previous equipment is low, and most employees choose to manually perform the light shielding glue bonding process, and generally perform the light shielding glue bonding from the top of the product, which will lead to a decrease in production rate and yield rate;

[0050] This method standardizes the actions of the process, reduces the risk of defective products due to human errors, improves production rate and yield, and is compatible with the shading glue bonding process of all small-size (mobile phone) screens.

[0051] The above is an exemplary description of the present invention in combination with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as such non-substantial improvements are made by adopting the method concept and technical solution of the present invention, or the concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
