The method for verifying the attaching overlapping degree of the liquid crystal display screen of the mobile phone as claimed in claim 2, wherein the method comprises the following steps: b. the method comprises the steps of reading the attaching overlapping degree of a first mobile phone liquid crystal display and a second mobile phone liquid crystal display, adjusting the longitudinal displacement and the transverse displacement of a two-dimensional connecting plate through a first adjusting screw rod and a second adjusting screw rod by a first adjusting handle and a second adjusting handle respectively, enabling a check point on the second mobile phone liquid crystal display on a guide shaft connected with a guide key on a guide shaft through a guide groove in a second dovetail plate through hole to coincide with a corresponding check point on a first mobile phone liquid crystal display placed on the bottom surface of a shell, namely enabling a connecting line of two check points corresponding to the first mobile phone liquid crystal display and the second mobile phone liquid crystal display to be perpendicular to a horizontal plane, enabling two check points corresponding to the first mobile phone liquid crystal display and the second mobile phone liquid crystal display to be imaged into an image recognition mechanism respectively through two reflecting surfaces on a reflecting mirror and symmetrically through a top end connecting line of an included angle formed between the two reflecting surfaces in parallel mode, and enabling the image recognition mechanism to read the overlapping degree of the first mobile phone liquid crystal display and the second mobile phone liquid crystal display.
5. The method for verifying the attaching overlapping degree of the liquid crystal display screen of the mobile phone as claimed in claim 2, wherein the attaching overlapping degree of the liquid crystal display screen of the mobile phone is as follows: c. pasting the first mobile phone liquid crystal display and the second mobile phone liquid crystal display, in order to move out the supporting frame and the reflector on the supporting frame from the coverage area of the first mobile phone liquid crystal display and the second mobile phone liquid crystal display, loosening the lifting adjusting nut on the guide shaft, pressing the guide shaft, and driving the sucker to press the second mobile phone liquid crystal display to the first mobile phone liquid crystal display along the guide groove on the second dovetail plate under the guide of the guide key by the guide shaft.
6. The method for verifying the attaching overlapping degree of the liquid crystal display screen of the mobile phone as claimed in claim 2, wherein the attaching overlapping degree of the liquid crystal display screen of the mobile phone is as follows: d. and taking out the finished product for later use, namely opening the cover plate when the adhesive between the first mobile phone liquid crystal display and the second mobile phone liquid crystal display is cured and the adhesive viscosity is greater than the adsorption force of the sucker, and taking out the first mobile phone liquid crystal display and the second mobile phone liquid crystal display which are stuck together.
