[0023] Example 1 Please see Figures 1-3 , Figure 1 This is a schematic diagram of the structure of a liquid crystal panel polarizer attachment mechanism according to an embodiment of the present invention; Figure 2 A side view of a liquid crystal panel polarizer attachment mechanism provided in an embodiment of the present invention; Figure 3 This is a top view schematic diagram of a liquid crystal panel polarizer attachment mechanism provided in an embodiment of the present invention.

[0024] As shown in the figure, the LCD panel polarizer attachment mechanism includes a frame 10, a panel stage 20, a polarizer stage 30, an attachment component 40, a first alignment component 50, and a second alignment component 60. Each component can be coordinated by a control system (not shown in the conventional figure) to achieve precise attachment of the LCD panel and the polarizer.

[0025] The rack 10, serving as the basic structure of the polarizer attachment mechanism for the LCD panel, can be made of metal, providing excellent structural stability. The rack 10 can be divided into three specific functional workstations: The LCD panel workstation is used for loading, carrying, conveying, and positioning LCD panels. The polarizer station is used for loading, carrying, conveying, and positioning polarizers. The attachment station is used to complete the final attachment work.

[0026] Preferably, the spacing between the three functional workstations can be customized according to actual production needs, and this application does not impose any restrictions on this.

[0027] The panel carrier 20 is movably mounted on the frame 10 and located within the LCD panel station. The panel carrier 20 is used to carry the LCD panels and transport them to the bonding station, facilitating subsequent bonding operations. Simultaneously, the first alignment component 50 can collect real-time position information of the LCD panels on the panel carrier 20, and perform alignment and correction on the panel carrier 20 to improve the accuracy of subsequent bonding.

[0028] In specific implementation, the first alignment component 50 includes a first alignment platform 51 and a first positioning module 52. The first alignment platform 51 is movably mounted on the frame 10 via a transmission structure (conventional component) such as a linear module and a sliding rail, facilitating the movement of the first alignment platform 51 relative to the frame 10 along the Y-axis. The panel carrier 20 is fixedly mounted on the bearing surface of the first alignment platform 51 to transport the LCD panel to the bonding station.

[0029] The first positioning module 52 is fixed on the frame 10 and located above the panel stage 20. Figure 3 Taking the direction shown as an example, the first positioning module 52 can collect the alignment position information of the LCD panel on the left and bottom of the panel stage 20 in real time, providing a data basis for the subsequent alignment and correction of the panel stage 20.

[0030] The polarizer stage 30 is movably mounted on the frame 10 and located within the polarizer station. The polarizer stage 30 is used to carry and transport polarizers, facilitating subsequent bonding operations. Simultaneously, the second alignment component 60 can collect real-time position information of the polarizers on the polarizer stage 30, correcting and adjusting the stage 30 to improve the accuracy of subsequent bonding.

[0031] In specific implementation, the second alignment component 60 includes a second alignment platform 61 and a second positioning module 52. The second alignment platform 61 is movably mounted on the frame 10 via a transmission structure (conventional component) such as a linear module and a sliding rail, facilitating the movement of the second alignment platform 61 relative to the frame 10 along the Y-axis. The polarizer stage 30 is fixedly mounted on the bearing surface of the second alignment platform 61 to realize the transport of the polarizer.

[0032] The second positioning module 62 is fixed on the frame 10 and located above the polarizer stage 30, so as to Figure 3 Taking the direction shown as an example, the second positioning module 62 can collect the alignment position information of the polarizer on the left and bottom sides of the polarizer stage 30 in real time. It works in conjunction with the first alignment platform 51 to perform translational adjustment of the panel stage 20 and / or Y-axis and / or rotational adjustment around the Z-axis on the polarizer stage 30, thereby improving the bonding accuracy of the LCD panel and the polarizer, increasing production efficiency and yield, and reducing production costs.

[0033] Preferably, in this embodiment, the first alignment platform 51 and the second alignment platform 61 are adopted from the XYR three-axis alignment platform of Beijing Zhuoli Hanguang Instrument Co., Ltd., which can realize translational adjustment in the X and Y axis directions and rotational adjustment around the Z axis.

[0034] Based on the above, the LCD panel polarizer attachment mechanism may further include a third positioning module 70. The third positioning module 70 is located below the attachment mechanism 40 and is used to perform secondary precision positioning of the polarizer picked up by the attachment mechanism 40, allowing the first alignment component 50 to perform secondary alignment and correction on the panel stage 20, further improving the attachment accuracy. Preferably, the first positioning module 52, the second positioning module 62, and the third positioning module 70 can all be vision cameras.

[0035] In some preferred embodiments, the attachment component 40 is movably mounted on the frame 10 and located within the attachment station, for picking up polarizers from the polarizer stage 30 and precisely attaching them to the liquid crystal panel on the panel stage 20.

[0036] In specific implementation, such as Figure 4 As shown, the attachment assembly 40 includes an attachment slide 41, an attachment slider 42, and an attachment lifting seat 43. The attachment slide 41 is movably mounted on the frame 10 via a transmission structure (conventional component) such as a linear module and a sliding rail, facilitating the movement of the attachment slide 41 relative to the frame 10 along the X and Z axes. The attachment slide 41 is provided with a steel strip 44, and the side of the steel strip 44 facing away from the attachment slide 41 has an adhesive layer (not shown), used to attach polarizers from the polarizer stage 30.

[0037] The attaching slider 42 is movably mounted on the attaching slide 41 and can move relative to the attaching slide 41 along the X-axis. One end of the attaching slider 42 is tumbled to the steel strip 44 via a roller 45. By moving the roller 45 along the X-axis, the attaching slider 42 compresses the steel strip 44 to adhere the polarizer or attach the polarizer to the LCD panel.

[0038] The attachment lifting seat 43 is movably mounted on the attachment slide 41 and can move relative to the attachment slide 41 along the Z-axis. One end of the steel belt 44 is connected to the attachment slide 41, and the other end is connected to the attachment lifting seat 43. The angle of the steel belt 44 can be adjusted by using the attachment lifting seat 43.

[0039] by Figure 3 , Figure 4 Taking the indicated direction as an example, the specific attachment process is as follows: The panel stage 20 carries the LCD panel and moves along the Y-axis to the bonding station. At the same time, the polarizer stage 30 carries the polarizer and moves along the Y-axis to feed the polarizer paper to the bonding assembly 40. During this process, the first alignment assembly 50 and the second alignment assembly 60 complete the alignment and correction of the panel stage 20 and the polarizer stage 30. The attached slide 41 descends along the Z-axis, and at the same time the attached lifting seat 43 descends along the Z-axis, so that the steel strip 44 is laid out horizontally in the transverse direction. Then the attaching slider 42 moves from left to right, the roller 45 squeezes the steel strip 44, and the polarizer is picked up through the adhesive layer on the steel strip 44. Then the attaching slide 41 rises to complete the polarizer pickup. After the polarizer is picked up, the attachment slide 41 rises along the Z-axis and moves to the left along the X-axis to above the panel stage 20. During this process, the panel stage 20 is repositioned and corrected by the third positioning module 70 and the first correction component 50 to further improve the attachment accuracy.

[0040] The attaching slide 41 descends along the Z-axis to bring the polarizer close to the LCD panel. At the same time, the attaching slider 42 drives the roller 45 to move from right to left to squeeze the steel strip 44. Meanwhile, the attaching lifting seat 43 rises along the Z-axis to lift the right end of the steel strip 44 and separate it from the polarizer. Through the coordinated action of the attaching slider 42 and the attaching lifting seat 43, the polarizer is accurately attached to the LCD panel, completing the attachment operation, and this process is repeated.

[0041] Preferably, the polarizer stage 30 may be provided with a vacuum adsorption area for adsorbing the polarizer, so as to prevent the polarizer from shifting or deviating during the movement of the polarizer stage 30.

[0042] In some preferred embodiments, the liquid crystal panel polarizer attachment mechanism further includes a loading gripper 80 and a polarizer tray 90. Specifically, the loading gripper 80 is movably mounted on the frame 10 and can move relative to the frame 10 along the Y-axis, used to grip polarizers from the polarizer tray 90 and transfer them to the polarizer stage 30. Preferably, the loading gripper 80 can be composed of multiple suction cups.

[0043] The polarizer box 90 is used to load polarizers and facilitates the gripping of the polarizers by the loading jaws 80. In specific implementations, such as... Figure 5 As shown, the polarizer cassette 90 includes a cassette body 91, a lifting base plate 92, and a height-finding sensor 93. The lifting base plate 92 is vertically and vertically mounted inside the cassette body 91 along the Z-axis.

[0044] A height-finding sensor 93 is mounted on the housing 91. The sensor detects the stacking height of the remaining polarizers in the housing 91 and forms a closed-loop control with the lifting base plate 92. The height of the lifting base plate 92 is adjusted according to the stacking height to keep the uppermost polarizer within the gripping height range of the feeding jaws 80. Preferably, the height-finding sensor 93 can be an infrared sensor.

[0045] Furthermore, the LCD panel polarizer attachment mechanism also includes a release film removal assembly 100. This assembly removes the release film from the polarizer after the attachment assembly 40 has picked it up, facilitating the attachment assembly to attach the polarizer to the LCD panel. In specific implementations, such as... Figure 6 , Figure 7 As shown, the film-tearing assembly 100 includes a film-tearing slide 101, a film-tearing roller 102, and a film-tearing gripper 103. The film-tearing slide 101 is movably mounted on the frame 10 and can move relative to the frame 10 along the X-axis. The film-tearing roller 102 and the film-tearing gripper 103 are movably mounted on the film-tearing slide 101 and can move synchronously relative to the film-tearing slide 101 along the Y-axis.

[0046] by Figure 3 , Figure 6 Taking the direction shown as an example, the specific film-peeling process is as follows: After the attachment assembly 40 completes the picking up of the polarizer, the polarizer stage 30 retracts downward along the Y-axis, and the film peeling assembly 100 moves along the X-axis to below the attachment assembly 40. At the same time, the film peeling roller 102 and the film peeling gripper 103 move synchronously along the Y-axis to the lower left corner of the polarizer. The surface of the film-peeling roller 102 has an adhesive layer (not shown). The film-peeling roller 103 picks up the release film from the lower left corner of the polarizer. The film-peeling claw 103 clamps the corner of the release film picked up by the film-peeling roller 102. Then, by moving the film-peeling slide 101 and the film-peeling claw 103, the release film is peeled off in a downward to upper right direction, which makes it easier for the attachment mechanism 40 to attach the polarizer to the liquid crystal panel.

[0047] The first alignment component 50 and the second alignment component 60 are used to align and correct the panel stage 20 and the polarizer stage 30, which makes it easier for the attachment mechanism 40 to pick up the polarizer and attach it accurately to the LCD panel, thereby improving production yield and efficiency and reducing production costs.

[0048] Example 2 This embodiment provides a polarizer attachment device, which includes the liquid crystal panel polarizer attachment mechanism described in the above embodiment, to improve the attachment accuracy between the liquid crystal panel and the polarizer.

[0049] In summary, the polarizer attachment mechanism and polarizer attachment equipment for liquid crystal panels provided by this utility model, compared with the prior art, are designed with a first alignment component and a second alignment component. The first alignment component collects the position information of the liquid crystal panel on the panel carrier and the position information of the polarizer on the polarizer carrier in real time, and performs alignment correction on the panel carrier and the polarizer carrier. This facilitates the attachment mechanism to pick up the polarizer and attach it accurately to the liquid crystal panel, thereby improving production yield and efficiency and reducing production costs.
