Description

Technical Field

[0001] The present invention relates to the field of automated production technology, and in particular to an air-floating laminating mechanism for an OCA product. Background Art

[0002] Flat panel display devices are human-computer interaction carriers that realize the display of text and images. They are mainly composed of display modules, backlight modules and touch modules. The display module is composed of display panels, polarizers, driver chips (ICs), circuit boards (PCBs and FPCs) and other components. The production of flat panel display devices is divided into front-end arrays, box-making processes and back-end module assembly processes. The front-end process is used to produce display panels, and the back-end process is used to assemble components such as display panels, polarizers, backlight modules, and touch modules into flat panel display devices. The display panel is the main component for realizing the display function. In order to assemble it into a display device, polarizers need to be attached to both sides of the panel (LCD panels need to have a polarizer attached to the upper and lower sides, and OLED panels need to have a polarizer attached to the top) to achieve directional propagation of light.

[0003] To ensure the stability of the attachment between the polarizer and the OLED panel, the bonding process requires that transparent OCA glue be attached to the OLED panel first. The OCA glue can achieve adhesion to form an OCA product. After adhesion, the OCA product needs to be positioned corrected to facilitate the next step. Currently, the position correction of traditional OCA products is to lift the product up and move it to the correction mechanism through a mechanical claw for correction. This method can easily damage the product and cause scratches. Therefore, we have specially proposed an OCA product air flotation bonding mechanism to avoid the above problems.

[0027] The OCA product air-floating bonding mechanism of the preferred embodiment of the present invention is as follows: Figure 1-5 As shown, it includes a horizontally arranged air-floating plate group 1 and a support module 2 provided below the air-floating plate group 1; the air-floating plate group 1 includes an air-floating top plate 1a, an air-floating station 3 is provided on the upper surface of the air-floating top plate 1a, an air-floating cavity 4 is provided on the lower surface of the air-floating top plate 1a, an air port 5 communicating with the air-floating cavity 4 is provided on the air-floating station 3, and a plurality of air ports 5 are provided and evenly arranged on the air-floating station 3. The air-floating plate group 1 also includes an air-floating bottom plate 1b provided below the air-floating top plate 1a to seal the air-floating cavity 4, and an air nozzle 6 for supplying air is provided on the air-floating bottom plate 1b corresponding to the air-floating cavity 4; the air-floating station 3 and A first detection window 7 and a second detection window 8 are coaxially penetrated on the air-floating bottom plate 1b, and a sealing member 9 for simultaneously sealing the first detection window 7 and the second detection window 8 is further provided in the air-floating cavity 4. A detection channel 10 connecting the first detection window 7 and the second detection window 8 is penetrated on the sealing member 9; the overall structure of the present invention is simple, the structural design is optimized and reasonable, and it is convenient to be integrated into the production line. The air flow sprayed by the air port 5 on the air-floating station 3 can blow the workpiece upward to make it float in the air, thereby achieving the purpose of moving the workpiece upward and avoiding direct contact with the workpiece to cause it to be scratched.

[0028] Preferably, the first detection window 7 and the second detection window 8 are both long strips, and a plurality of detection positions 11 are provided on the lower surface of the air-floating bottom plate 1b along the length direction of the second detection window 8. A fixing seat 13 for installing a detector 12 can be removed from the detection position 11, which can facilitate the installation of an optical fiber probe to detect the position of the workpiece. Specifically, the detection position is a fixing screw hole, which is convenient for fixing the fixing seat 13 by screws.

[0029] Preferably, the blocking member 9 is integrally formed on the bottom surface of the air flotation cavity 4 and can be integrally machined by a lathe or integrally cast.

The amount can effectively keep the product in a horizontal, stable and static state, and avoid lateral displacement deviation caused by the force direction corresponding to the deformation part of the air-floating top plate being not perpendicular to the lower surface of the product after the product floats up. Specifically, the air outlets on both sides adjacent to the second detection window are generally arranged vertically, and the air outlet ends of the air outlets on the deformation area of ​​the air-floating top plate are inclined toward the second detection window, and the inclination angle gradually decreases in the direction away from the second detection window, thereby adapting to different deformation amounts of the air-floating top plate, further balancing the force conditions of the floating product, ensuring that all parts of the product are level, and greatly improving the correction accuracy of the correction mechanism.
