For the LCD module, it is composed of two parts, namely FPC and LCD. For LCD, according to different product requirements, LCD screen size is various, screen center position is indefinite; the FPC is a flexible circuit board made of flexible materials, has the characteristics of high wiring density, light weight, thin thickness and good flexibility, and meanwhile, the FPC has various sizes and forms are easy to change irregularly in the production process, so that after the connecting position of the FPC is pressed by the jig pressing head, the position of the LCD can change due to the deformation of the FPC; the above reasons are all that the screen center of the LCD is not at the center of the field of view of the AOI camera, thereby affecting the detection of the AOI camera. When the visual field center of the AOI camera cannot be adjusted along with the LCD size change, the automatic pressing mechanism is required to adjust the central position of the LCD screen, so in this embodiment, the first sliding device 11, the second sliding device 12 and the third sliding device 13 which are arranged side by side can respectively adjust the LCD module jigs on the three stations along the direction of the rotating shaft 8 (in this embodiment, the X-axis direction) and the adjusting slider assembly 3 can adjust the three stations along the direction perpendicular to the rotating shaft 8 (in this embodiment, the Y-axis direction), so that the automatic pressing mechanism can be adjusted in time when the LCD size and the length form of the FPC change, thereby ensuring the success rate of pressing.
The rotating shaft 8 connected with the plurality of sliding devices can rotate along the axis under the drive of the motor 6, and in the rotating process of the rotating shaft 8, the pressing roller assembly fixed on the rotating shaft can be driven to move towards the connection part of the FPC, and after the rotating shaft 8 rotates for a certain angle, the pressing roller assembly is attached to the FPC and is pressed tightly, so that the pressing action is completed; the rotatable angle range of the rotating shaft 8 is controlled by the sensor assembly 5 positioned at one side of the first sliding device 11, when the sensor assembly 5 receives a signal that the pressing roller assembly reaches the corresponding position, the motor 6 is controlled to stop rotating, and the pressing roller assembly does not move downwards any more.
Since the deformation of the FPC may cause the position of the LCD screen to be offset left and right, and the rotational offset, in this embodiment, the secondary alignment mechanism assembly 4 disposed on the opposite side of the rotating shaft 8 mainly corrects the shape of the LCD screen through the relative movement clamped on the two sides, so that the center of the screen is located at the center of the field of view of the AOI camera.
