However, existing binding tooling has the following problems: 1. Low positioning accuracy: During the assembly process of the glass and the canopy frame, the lack of a precise positioning device can easily lead to inaccurate fit between the glass and the frame, affecting the sealing and overall strength of the canopy; 2. Weak fixation: During the binding process, due to the unreasonable design of the fixing device, it is unable to provide sufficient pressure and stability, causing the glass to easily shift during the bonding process, affecting the binding quality; due to the difference between the fixing device and the fuselage contour, the canopy is deformed after binding, reducing the matching degree with the fuselage. 3.
