Then the adsorption platform 15 moves in the X-axis direction, and the soft support surface 22 moves in the Y-axis direction, so that the upper polarizer and the lower polarizer are vertically aligned; the detection camera 56 of the visual detection component 5 located between the upper bonding platform 1 and the lower bonding platform 2 moves in the Y-axis direction, the top camera 57 detects the upper polarizer, and the bottom camera 58 detects the lower polarizer downward. At the same time, the upper polarizer and the lower polarizer are detected. The offset angle and the X- and Y-axis offset distances, the upper bonding platform 1 and the lower bonding platform 2 are continuously corrected according to the detection offset data of the detection camera 56; until the error is less than the preset value, the upper polarizer and the lower polarizer are then accurately bonded; during the bonding process, the offset data is detected and automatically corrected for the offset data, which improves the bonding accuracy and ensures the bonding quality.

[0051] The upper bonding platform 1 includes a bonding gantry 11 arranged horizontally along the X-axis direction, the bonding gantry 11 is provided with a first X-axis linear module 12 along the X-axis direction, the first X-axis linear module 12 is provided with a first Z-axis linear module 13 arranged longitudinally, the first Z-axis linear module 13 is provided with a Z-axis sliding seat 14, a correction platform 16 is provided on the Z-axis sliding seat 14, and a plurality of adsorption holes for vacuum adsorption of the upper film are formed on the bottom surface of the adsorption platform 15; the upper polarizer is vacuum adsorbed through the adsorption holes and can be positioned on the bottom surface of the adsorption platform 15, so that the adsorption platform 15 can move in the X-axis direction of the bonding gantry 11 to adsorb the upper film to be bonded, and move it to the vicinity of the lower bonding platform 2.

When the difference in offset is small, the XYR alignment platform 19 is used to adjust the position, thereby ensuring that the deviation values ​​of the upper polarizer and the lower polarizer in the X, Y and R axis directions are less than the preset values.

[0053] Preferably, the XYR alignment platform 19 is an existing three-axis parallel alignment mechanism purchased from outside.

The rolling group 23 moves transversely to drive the lifting roller pressing wheel 24 to roll the lower polarizer onto the bottom surface of the upper polarizer. When the deviation value between the upper polarizer and the lower polarizer is less than the preset value, the adsorption platform 15 moves in the Z-axis direction to align and fit the upper polarizer and the lower polarizer with high precision.

The lifting roller pressure wheel 43 and the drive roller 42 roll together, and after the lifting roller pressure wheel 43 presses the lower diaphragm against the upper diaphragm, the lifting roller pressure wheel 43 will roll the lower diaphragm. At the same time, the drive roller 42 rolls at the same time to provide rolling support for the lifting roller pressure wheel 43, thereby improving the rolling stability of the lifting roller pressure wheel 43 and further improving the accuracy of the lamination.

[0061] Preferably, rolling vertical plates 44 are installed at both ends of the rolling drive plate 41, and the driving roller 42 can be rotatably installed between the two rolling vertical plates 44. A semicircular groove 45 is formed on the top of the rolling vertical plate 44 for installing the end of the lifting roller pressure wheel 43. The driving roller 42 is installed on the rolling vertical plate 44 through a bearing member, and both ends of the lifting roller pressure wheel 43 are installed in the semicircular groove 45 through bearing members. The design of the semicircular groove 45 allows the lifting roller pressure wheel 43 to be quickly replaced, so as to adapt to diaphragms of different sizes.

[0062] Furthermore, the rolling bottom plate 27 is installed with a bottom lifting cylinder 46, and the driving end of the bottom lifting cylinder 46 is connected to the rolling driving plate 41. Under the drive of the bottom lifting cylinder 46, the lifting roller 43 installed on the rolling driving plate 41 can push the lower diaphragm against the upper diaphragm, and roll the lower diaphragm to the bottom surface of the upper diaphragm for bonding and covering.
