TECHNICAL FIELD
[0001] The utility model relates to the technical field of electrochromic technology, especially relates to a packaging mould for electrochromic glass. BACKGROUND
[0002] The electrochromic glass is generally composed of a multilayer structure, at least including an upper substrate and a lower substrate, and an electrochromic layer sandwiched between the upper substrate and the lower substrate, which is generally formed by injecting an electrolyte solution into the cavity between the upper substrate and the lower substrate. The electrochromic glass packaging needs to be completed by a packaging mould. In the film cavity of the packaging mould, the electrolyte solution is injected between the upper and lower substrates and a certain pressure is applied to complete the packaging. During the packaging process, special attention should be paid to maintaining the balance of the pressure and the smoothness of the liquid injection channel. In the existing technology, during the packaging process of the electrochromic glass with an arc surface, a support air bag is generally used to support the lower substrate to ensure that the support body can be attached to the curved surface of the lower substrate and provide stable and uniform support force. However, the stability of the air bag pressure can cause problems in the packaging of the electrochromic glass with an arc surface. When the air bag pressure fluctuates and decreases, the support force of the air bag decreases, causing the liquid injection channel to be misaligned with the electrochromic layer of the electrochromic glass, resulting in poor packaging of the electrochromic glass. The electrolyte solution cannot be injected into the electrochromic layer through the liquid injection channel, which may also cause the electrolyte solution to leak, causing corrosion to the packaging mould.
