[0052] A polarizing plate adjustment machine, as shown in Figure 1, includes...

[0053] Bottom frame 1, the top surface of bottom frame 1 is provided with,

[0054] The movable receiving platform 2 can be controlled to move on the top surface;

[0055] The sheet metal clamping module 3 can be controlled to rise and fall above the movable receiving platform 2;

[0056] Image acquisition module 4 is positioned at a first set distance from the top surface to acquire position images of the plate 9 to be adjusted;

[0057] The image processing module is connected to the mobile receiving station 2 and the image acquisition module 4. The image processing module receives the position image and outputs an adjustment signal to the mobile receiving station 2.

[0058] Specifically, this utility model provides a polarizing plate adjustment machine, which uses a movable receiving platform 2 to clamp the lower part of the plate to be adjusted 9, and a plate clamping module 3 to clamp the upper part of the plate to be adjusted 9. An image acquisition module 4 acquires the position deviation image of the plate to be adjusted 9, and cooperates with the image processing module to output an adjustment signal to the movable receiving platform 2 to accurately adjust the position of the plate to be adjusted 9. The adjustment accuracy is high, the operation speed is fast, and the labor intensity of manual labor is reduced.

[0059] In a preferred embodiment, referencing Figure 6 The material to be adjusted 9 includes a liquid crystal panel 91 and a polarizing plate 92 disposed above the liquid crystal panel 91.

[0060] Specifically, polarizing plate 92 is the upper part of the material 9 to be adjusted, and liquid crystal plate 91 is the lower part of the material 9 to be adjusted.

[0061] In a preferred embodiment, referencing Figure 2 Mobile receiver 2 includes,

[0062] The first gripper 21 is used to grip the LCD panel 91;

[0063] The first gripper cylinder 22 is connected to the first gripper 21 and is used to control the first gripper 21 to clamp the LCD panel 91;

[0064] The position adjustment component 23 is connected to the plate 9 to be adjusted and is used to adjust the X, Y, and θ positions of the LCD panel 91.

[0065] Specifically, this ensures that the combination of each polarizing plate 92 and liquid crystal panel 91 meets a high standard of installation accuracy, making the product quality more stable and consistent.

[0066] In a preferred embodiment, the position adjustment component 23 includes,

[0068] The second motor 232 is perpendicular to the first motor 231;

[0075] The second gripper cylinder 34 is located above the second gripper 33 and is used to drive the second gripper 33 to clamp the polarizing plate 92.

[0076] Specifically, the second gripper 33 can accurately reach the appropriate height under the drive of the first lifting electric cylinder 32, and then firmly clamp the polarizing plate 92 under the action of the second gripper cylinder 34, so as to prevent the polarizing plate 92 from shifting in subsequent adjustment operations (such as adjusting the position of the liquid crystal panel 91 by moving the receiving stage 2 or adjusting the angle of the entire plate), thereby ensuring the adjustment accuracy.

[0077] In a preferred embodiment, referencing Figure 4 The image acquisition module 4 includes,

[0078] Fixture 41;

[0079] Image acquisition device 42 is mounted on fixed base 41;

[0081] Specifically, the image acquisition unit 42 is a camera, which captures the positional deviation (number of pixels in the image) between the liquid crystal panel 91 and the polarizing plate 92.

[0082] In a preferred embodiment, referencing Figure 5 It also includes an ultraviolet irradiation module 5, which is positioned at a second predetermined distance from the top surface. The ultraviolet irradiation module 5 includes...

[0085] The third lifting cylinder 53 is connected to the illumination lamp 52 and is used to move the illumination lamp 52.

[0086] Specifically, the component is first placed on the movable receiving stage 2, the LCD panel 91 is clamped and fixed, the panel clamping module 3 is lowered to clamp the polarizing plate 92, and then the movable receiving stage 2 moves on the track to the illumination lamp 52. After the position of the polarizing plate 92 is determined, ultraviolet irradiation curing is performed, the image is confirmed, the receiving stage is withdrawn, and the operation is finally completed.

[0087] In a preferred embodiment, referencing Figure 1 It also includes multiple sequentially connected enclosure panels 6, located on the outer side of the top surface. The enclosure panels 6 are connected to the top surface to form a workspace, and the workspace contains...

[0088] 2. Mobile receiving platform, 3. Sheet clamping module, 4. Image acquisition module, 5. Image processing module, and 6. Ultraviolet irradiation module.

[0089] Specifically, above the bottom frame 1, the upper three sides of the bottom frame 1 are surrounded by the enclosure 6 to form a workspace. The sheet metal structure can effectively isolate the external environment and provide a clean working environment for the internal working parts.

[0090] Meanwhile, the sheet metal enclosure 6 can also provide some shielding and protection against potential electromagnetic interference or static electricity, ensuring the normal operation of internal electrical equipment.

[0091] In a preferred embodiment, the image processing module includes,

[0092] An image processor (specifically a computer) is connected to the image acquisition module 4 and is used to process the position image of the plate 9 to be adjusted.

[0093] The control panel (not shown in the figure, the control panel is laid flat inside the enclosure 6) is connected to the image processor and the moving receiving platform 2, and is used to control the operation and communication of the entire mechanism.

[0094] Specifically, the image processor calculates the movement distances corresponding to the X, Y, and θ motors, communicates with the control board via RS232, and controls the adjustment of the first motor 231, the second motor 232, and the third motor 233. Then, the image is captured and the motors are fine-tuned repeatedly until the specifications are met.

[0095] The design is based on a Microchip 32-bit control board, with a communication interface that connects to an image processing computer and a control interface that connects to the X, Y, and θ motors.

[0096] In a preferred embodiment, a button box 7 is provided on the first side of the bottom frame 1 for sending commands to open the LCD panel control box (driver box 8);

[0097] The second side of the bottom frame 1 is provided with a drive box 8, which is connected to the button box 7 and the plate to be adjusted 9. It is used to output the image to the LCD panel 91, light up the LCD panel 91, and serve as a reference point during image processing.

[0098] The first side is adjacent to the second side.

[0099] Specifically, this utility model uses a movable receiving platform 2 to fix the LCD panel 91. After the polarizing plate 92 is clamped by the plate clamping module 3, it rises. The button box 7 opens the drive box 8, and the drive box 8 lights up the LCD panel 91. The camera captures the position image and transmits it to the computer. The computer processes the image and outputs a signal to the MCU (microcontroller unit) control board. The control board then controls the three motors on the movable receiving platform 2 to adjust the position of the LCD panel 91 until it reaches the specified size, thus achieving automatic adjustment of the polarizing plate 92. Then, it is irradiated and cured by the ultraviolet irradiation module 5. Finally, the image is confirmed and the receiving platform is removed to complete the operation.

[0100] The original manual adjustment of polarizing plate 92 was replaced with automatic machine adjustment, reducing manual labor, maintaining stable quality, and improving production efficiency.

[0101] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
