Examples of these preferred embodiments are illustrated in the drawings. The embodiments of this utility model shown in and described with reference to the drawings are merely exemplary, and this utility model is not limited to these embodiments.

In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," and "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the accompanying drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0036] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the solution according to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0037] This utility model provides a bonding device for LCM modules and glass cover plates, used to bond two LCM modules to a glass cover plate to obtain a dual-screen display. (See also...) Figures 1 to 12 The bonding device mainly includes a bonding unit 1, an LCM module transfer mechanism 2, and a CG transfer and film-tearing mechanism 3 connected to the frame platform 100. The bonding unit 1 includes a lower bonding platform 11, an upper bonding platform 12, an LCM visual alignment component 13, and a CG visual alignment component 14.

[0038] The lower bonding platform 11 is located at the first end of the bonding unit 1, and is used to simultaneously load two LCM modules. The upper bonding platform 12 extends along a second direction (in this embodiment, the width direction of the frame platform 100) and is configured to reciprocate between the upper part of the lower bonding platform 11 and the second end of the bonding unit 1. The upper bonding platform 12 is used to load a glass cover and move the glass cover to the upper part of the lower bonding platform 11.

[0039] The LCM module transfer mechanism 2 is mounted transversely above the lower bonding platform 11 along a first direction (the length direction of the frame platform 100 in this embodiment). The LCM module transfer mechanism 2 is used to simultaneously pick up and transfer two LCM modules fed in from a previous process (e.g., the LCM module loading and cleaning process) to the lower bonding platform 11. The CG transfer and film-removing mechanism 3 is mounted transversely above the upper bonding platform 12 along the first direction. The CG transfer and film-removing mechanism 3 is used to pick up and transfer the glass cover plate fed in from a previous process (e.g., the bonding process of the glass cover plate and OCA optical adhesive) to the upper bonding platform 12, and to remove the OCA optical adhesive bonded to the glass cover plate.

[0040] The LCM visual alignment component 13 is disposed below the LCM module transfer mechanism 2, and is used to visually position the two LCM modules gripped on the LCM module transfer mechanism 2. The CG visual alignment component 14 is disposed below the bonding platform 12, and is used to visually position the glass cover plate mounted on the bonding platform 12.

[0041] The upper bonding platform 12 is configured to flip the loaded glass cover so that the OCA optical adhesive faces downwards before moving it above the lower bonding platform 11. The lower bonding platform 11 is configured to lift the two loaded LCM modules upwards so that the two LCM modules are bonded to the glass cover through the OCA optical adhesive to obtain a dual-screen display.

[0042] It should be noted that the glass cover plate described in this embodiment is a glass cover plate with OCA optical adhesive. When the CG transfer and film-removing mechanism 3 picks up and transfers the glass cover plate to the bonding upper platform 12, the OCA optical adhesive is facing upwards. At this time, the CG transfer and film-removing mechanism 3 removes the protective film on the surface of the OCA optical adhesive. Then, the bonding upper platform 12 flips the glass cover plate so that the OCA optical adhesive faces downwards. After that, the bonding upper platform 12 moves the glass cover plate above the bonding lower platform 11, where it is bonded to the two LCM modules on the bonding lower platform 11 through the OCA optical adhesive.

[0043] In this embodiment, see Figures 4 to 6 and combined Figures 1 to 3 The bonding platform 11 includes a vacuum generating mechanism 11a and two LCM support mechanisms 11b. The vacuum generating mechanism 11a includes a vacuum chamber assembly 111, a first lifting drive assembly 112 and a vacuum pumping assembly 113. Each LCM support mechanism 11b includes a UVW platform 114, a second lifting drive assembly 115 and an LCM support stage 116.

[0044] The vacuum chamber assembly 111 is vertically and flexibly connected to the frame platform 100 via the first lifting drive assembly 112. The vacuum pumping assembly 113 is connected to the vacuum chamber assembly 111. The vacuum chamber assembly 111 has an open upper receiving cavity 117. The vacuum chamber assembly 111 is configured to align with the upper platform 12 to close the receiving cavity 117. The UVW platform 114 is connected to the frame platform 100. The second lifting drive assembly 115 is movably connected to the UVW platform 114. The power output end of the second lifting drive assembly 115 extends through the bottom of the vacuum chamber assembly 111 into the receiving cavity 117. The LCM carrier platform 116 is located within the receiving cavity 117 and vertically and flexibly connected to the power output end of the second lifting drive assembly 115. The LCM carrier platform 116 is used to load LCM modules.

[0045] In this embodiment, see Figure 7 and combined Figures 1 to 3 The bonding platform 12 includes a first linear drive assembly 121, a flip drive assembly 122, and a CG adsorption stage 123. The first linear drive assembly 121 is connected to the frame platform 100 and extends along a second direction between the upper part of the bonding lower platform 11 and the second end of the bonding unit 1. The flip drive assembly 122 is movably connected to the first linear drive assembly 121. The CG adsorption stage 123 is rotatably connected to the flip drive assembly 122 and is used to load the glass cover plate.

[0046] It should be noted that, Figure 1 and Figure 3 The image shows the CG adsorption platform 123 flipped up so that the bearing surface is facing down. Figure 7 The image shows the CG adsorption stage 123 flipped up so that the bearing surface is facing upwards.

[0047] In this embodiment, see Figure 8 and Figure 10 The LCM visual alignment component 13 is disposed on the first side of the bonding platform 11 and located below the LCM module transfer mechanism 2. When the LCM module transfer mechanism 2 picks up and transfers two LCM modules above the LCM visual alignment component 13, the LCM visual alignment component 13 performs visual positioning on the two LCM modules picked up on the LCM module transfer mechanism 2.

[0048] In this embodiment, see Figure 9 and Figure 10The CG visual alignment component 14 is disposed on the second side of the bonding platform 11 and located below the first linear drive component 121. When the CG adsorption stage 123 moves above the CG visual alignment component 14 based on the drive of the first linear drive component 121, the CG visual alignment component 14 performs visual positioning of the glass cover plate mounted on the CG adsorption stage 123.

[0049] As a preferred embodiment, such as Figures 1 to 3 As shown, the bonding device in this embodiment is provided with two bonding units 1, which are arranged in parallel in the first direction and extend along the second direction respectively.

[0050] In this embodiment, see Figure 11 and combined Figures 1 to 3 The LCM module transfer mechanism 2 includes a second linear drive assembly 21, a first gripping robot assembly 22, and a second gripping robot assembly 23. The second linear drive assembly 21 is a dual-actuator linear drive assembly, which is mounted transversely above the bonding platform 11 along the first direction. The first gripping robot assembly 22 and the second gripping robot assembly 23 are movably connected to the second linear drive assembly 21. Specifically, the first gripping robot assembly 22 is configured to simultaneously grip and move two LCM modules, and the second gripping robot assembly 23 is configured to grip and move the dual-screen display obtained through bonding.

[0051] In this embodiment, see Figure 12 and combined Figures 1 to 3 The CG transfer and film-tearing mechanism 3 includes a third linear drive assembly 31, a third gripping robot assembly 32, and a film-tearing robot assembly 33. The third linear drive assembly 31 is a dual-actuator linear drive assembly, which is transversely mounted above the bonding platform 12 along the first direction. The third gripping robot assembly 32 and the film-tearing robot assembly 33 are movably connected to the third linear drive assembly 31. The third gripping robot assembly 32 is configured to grip and move the glass cover plate, and the film-tearing robot assembly 33 is configured to peel off the protective film on the surface of the OCA optical adhesive on the glass cover plate.

[0052] The bonding device described above operates by including the following steps:

[0053] (1) The first gripping robot component 22 in the LCM module transfer mechanism 2 grips two LCM modules sent from the previous process (such as the LCM module loading and cleaning process), and transfers the two LCM modules to the top of the LCM vision alignment component 13, so that the LCM vision alignment component 13 can obtain the positioning information of the two LCM modules.

[0054] (2) After visual positioning is completed, the first gripping robot arm assembly 22 sends the two LCM modules into the bonding platform 11, specifically by placing the two LCM modules on the two LCM carrier platforms 116 in the bonding platform 11.

[0055] (3) The third gripping robot component 32 in the CG transfer and film-tearing mechanism 3 grips the glass cover plate fed from the previous process (e.g., the bonding process of the glass cover plate and OCA optical adhesive) and transfers it to the bonding platform 12. Specifically, the glass cover plate is placed on the CG adsorption stage 123 with the OCA optical adhesive bonded to the glass cover plate facing upward. Then, the film-tearing robot component 33 in the CG transfer and film-tearing mechanism 3 peels off the protective film on the surface of the OCA optical adhesive.

[0056] (4) After the film is removed, the bonding platform 12 flips the glass cover plate so that the OCA optical adhesive faces downward. Specifically, the flipping drive component 122 in the bonding platform 12 drives the CG adsorption stage 123 to flip, thereby causing the glass cover plate loaded on the CG adsorption stage 123 to flip so that the OCA optical adhesive attached to the glass cover plate faces downward.

[0057] (5) In the upper bonding platform 12, based on the drive of the first linear drive component 121, the CG adsorption stage 123 first moves the loaded glass cover plate above the CG visual alignment component 14, and the CG visual alignment component 14 obtains the positioning information of the glass cover plate; after the positioning is completed, the CG adsorption stage 123 then moves the loaded glass cover plate above the lower bonding platform 11.

[0058] (6) Based on the positioning information obtained in steps (1) and (5), the two LCM modules are precisely aligned with the glass cover by the initial adjustment of the first linear drive component 121 in the upper bonding platform 12 and the precise adjustment of the UVW platform 114 in the lower bonding platform 11.

[0059] (7) After precise alignment, the second lifting drive component 115 in the LCM carrier mechanism 11b drives the LCM carrier platform 116 to rise, so that the LCM module mounted on the LCM carrier platform 116 is attached to the OCA optical adhesive in the glass cover plate; at the same time, the first lifting drive component 112 in the vacuum generating mechanism 11a drives the vacuum chamber component 111 to rise and align with the CG adsorption stage 123 to close the receiving cavity 117, and the vacuum pumping component 113 pumps a vacuum so that the receiving cavity 117 forms a vacuum chamber, thereby allowing the two LCM modules and the glass cover plate to be tightly attached in a vacuum environment to obtain a dual-screen display.

[0060] (8) After bonding is completed, the first lifting drive assembly 112 drives the vacuum chamber assembly 111 to descend, the second lifting drive assembly 115 drives the LCM carrier platform 116 to descend, and the first linear drive assembly 121 drives the CG adsorption platform 123 to return to the second end of the bonding unit 1. At this time, the second gripping robot assembly 23 in the LCM module transfer mechanism 2 grips the bonded dual-screen display from the bonding lower platform 11 and sends the dual-screen display outside the bonding device for unloading.

[0061] In summary, the LCM module and glass cover plate bonding device provided in this embodiment integrates the LCM module transfer mechanism, CG transfer and film removal mechanism, lower bonding platform, upper bonding platform, LCM visual alignment component, and CG visual alignment component into a single automatic bonding device. This device is used to bond two LCM modules to a glass cover plate to obtain a dual-screen display. During the bonding and assembly process of the dual-screen display, the entire process—from loading the two LCM modules and glass cover plate, removing the OCA optical adhesive from the glass cover plate, to visual alignment of the two LCM modules and glass cover plate, mutual pressing and bonding, and finally unloading the bonded dual-screen product—is automated, thus improving production efficiency.

[0062] The above description is only a specific embodiment of this application. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this application, and these improvements and modifications should also be considered within the scope of protection of this application.
