Description
Technical Field

[0002] In the manufacturing process of LCD displays, a glass cover (CG) needs to be bonded to a touch-enabled display panel using OCA optical adhesive to obtain a display module protected by the glass cover. In some existing touch displays, in addition to detecting touch position information, it is also necessary to detect the pressure applied during touch to enable richer interaction methods. This requires attaching a film sensor (FS) capable of detecting touch pressure to the surface of the glass cover facing the display panel.

The bonding process between the glass cover plate and the display panel includes the following steps: (1) attaching OCA optical adhesive to region I of the glass cover plate; (2) attaching a film sensor to region II of the glass cover plate; and (3) bonding the display panel with the OCA optical adhesive located in region I. In the prior art, the process of attaching the film sensor to the glass cover plate is usually carried out manually or semi-manually using auxiliary fixtures, which reduces production efficiency.

[0038] Specifically, the flexible bonding stage 31c includes a first support base 311, a flexible carrier belt 312, a reciprocating lateral movement drive module 313, and a rolling mechanism 314.

The flexible carrier belt 312 is used to carry a membrane sensor (such as...). Figure 6 The image shows a membrane sensor 200. When the bonding robot mechanism 32 bonds the glass cover plate to the membrane sensor located on the flexible carrier belt 312, the rolling mechanism 314 presses the flexible carrier belt 312 upward, and the reciprocating lateral drive module 313 drives the rolling mechanism 314 to reciprocate laterally to roll the membrane sensor, so that the membrane sensor is tightly bonded to the glass cover plate.
[0039] Specifically, the rolling mechanism 314 includes a second support base 314a, a lifting drive module 314b, and a rolling shaft assembly 314c. The second support base 314a is movably connected to the reciprocating lateral drive module 313, the lifting drive module 314b is connected to the second support base 314a, and the rolling shaft assembly 314c is vertically connected to the output end of the lifting drive module 314b. When the bonding robot mechanism 32 bonds the glass cover plate to the membrane sensor located on the flexible carrier belt 312, the lifting drive module 314b drives the rolling shaft assembly 314c to rise and press against the flexible carrier belt 312, and the reciprocating lateral drive module 313 drives the second support base 314a to move the lifting drive module 314b and the rolling shaft assembly 314c reciprocally laterally, thereby rolling the membrane sensor.
[0040] As a preferred embodiment, the rolling shaft assembly 314c includes a lifting connecting plate 3141, a rolling shaft connecting plate 3142, and a rolling shaft 3143. The lifting connecting plate 3141 is vertically connected to the output end of the lifting drive module 314b, the rolling shaft connecting plate 3142 is connected to the lifting connecting plate 3141, and bearings 3144 are respectively provided at both ends of the rolling shaft connecting plate 3142. The rolling shaft 3143 is rotatably inserted into the bearings 3144.
[0041] Furthermore, in this embodiment, the middle part of the rolling shaft connecting plate 3142 is rotatably connected to the lifting connecting plate 3141 via a rotating shaft 3145, and a balance adjustment mechanism 3146 is respectively provided between the two ends of the rolling shaft connecting plate 3142 and the lifting connecting plate 3141. The balance adjustment mechanism 3146 is used to adjust the tilt angle of the rolling shaft connecting plate 3142, thereby adjusting the tilt of the rolling shaft 3143.
[0042] In this embodiment, see Figure 8 and combined Figures 2 to 4 The bonding robot mechanism 32 includes a second linear drive assembly 321 and a bonding robot assembly 322. The second linear drive assembly 321 extends along the first direction and connects between the bonding lower platform 31 and the CG loading unit 1. The bonding robot assembly 322 is movably connected to the second linear drive assembly 321 and is configured to grasp and move the glass cover plate.
[0043] In this embodiment, see Figure 9 and combined Figures 2 to 4The FS transfer and film-tearing robot mechanism 33 includes a third linear drive assembly 331, a transfer robot assembly 332, and a film-tearing robot assembly 333. The third linear drive assembly 331 is a dual-actuator linear drive assembly, which extends along the first direction and connects between the bonding lower platform 31 and the FS loading unit 2. The transfer robot assembly 332 and the film-tearing robot assembly 333 are movably connected to the third linear drive assembly 331. The transfer robot assembly 332 is configured to grasp and move the film sensor, and the film-tearing robot assembly 333 is configured to tear off the protective film on the surface of the film sensor mounted on the bonding lower platform 31.
[0044] The bonding unit 3 described above operates by including the following steps:
[0045] (1) The flexible bonding platform 31c moves to the underside of the FS transfer and film-tearing robot mechanism 33. The transfer robot assembly 332 picks up the film sensor from the FS feeding unit 2 and places the film sensor on the flexible bonding platform 31c. Then, the film-tearing robot assembly 333 tears off the release protective film on the surface of the film sensor.
[0046] (2) After the film is peeled off, the flexible bonding stage 31c moves to the underside of the FS vision alignment component 35, and the FS vision alignment component 35 obtains the positioning information of the film sensor mounted on the flexible bonding stage 31c.
[0047] (3) The bonding robot assembly 322 picks up the glass cover plate from the CG loading unit 1 and moves the glass cover plate above the CG vision alignment assembly 34, so that the CG vision alignment assembly 34 can obtain the positioning information of the glass cover plate picked up on the bonding robot assembly 322.
[0048] (4) The flexible bonding stage 31c moves the membrane sensor below the bonding robot arm mechanism 32, and the bonding robot arm assembly 322 moves the glass cover plate above the bonding lower platform 31. Based on the positioning information obtained in steps (2) and (3), the membrane sensor and the glass cover plate are precisely aligned through the initial adjustment of the first linear drive assembly 31a and the second linear drive assembly 321, and through the precise adjustment of the UVW platform 31b.
[0049] (5) After precise alignment, the bonding robot assembly 322 presses the glass cover plate down onto the membrane sensor of the flexible bonding stage 31c. Specifically, the rolling mechanism 314 is first driven to press the flexible carrier tape 312 upwards, and then the rolling mechanism 314 is driven to reciprocate laterally to roll the membrane sensor, ensuring a tight fit between the membrane sensor and the glass cover plate.
[0050] (6) After bonding is completed, the bonding robot assembly 322 grabs the bonded product (the membrane sensor and the glass cover after bonding) and moves the bonded product outside the device to the next operation process.
[0051] In summary, the film sensor bonding device provided in this embodiment integrates the CG feeding unit for supplying the glass cover plate, the FS feeding unit for supplying the film sensor, and the bonding unit for bonding the film sensor and the glass cover plate into a single automatic bonding device. From the feeding and supply of the glass cover plate, to the feeding and supply of the film sensor and the film peeling process, to the visual alignment of the glass cover plate and the film sensor, and finally the bonding of the film sensor and the glass cover plate and unloading for the next process, all processes are automated, thereby improving the bonding efficiency of the film sensor and the glass cover plate, and thus improving the production efficiency of the LCD screen.
[0052] 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.
