Description

Technical Field

[0001] The utility model relates to a lamination frame, in particular to a detachable modular lamination frame. Background Art

[0002] In the production process of photovoltaic modules, lamination is one of the key steps. First, the module undergoes a vacuum pumping stage. Under high temperature and vacuum conditions, the internal adhesive film melts and vacuum pumping is carried out. Then, the air bubbles in the adhesive film are discharged. Subsequently, the module enters the pressurization stage, and the pressure can reach up to 90 kPa at this time. Since the corners bear a relatively large pressure, the module often faces the risks of glass cracking or internal chip hidden cracking. To solve these problems, usually before the module enters the laminator, a pair of lamination frames are installed around it. These four frames are usually welded together and a layer of high-temperature resistant fabric is wound on the surface. The thickness of the frame usually matches the thickness of the target module or is slightly thicker. The existence of the lamination frame ensures uniform stress on the surface of the module and plays a role in protecting the processing surface.

[0003] The frame sizes of the above-mentioned modules usually need to be customized and cannot be universal or applied. Given that there are dozens of module versions and the size span is large, module manufacturers must customize a large number of lamination frames during the stocking process. Over time, this not only increases costs but also brings challenges in terms of storage. In addition, due to the fixed shape of the frame, during on-site use, operator errors often cause the frame to deform or crack, resulting in the scrapping of the entire frame and causing additional economic losses. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is to provide a detachable modular lamination frame, which can not only freely adjust the length of the frame as needed, significantly expand its application scenarios, but also greatly reduce the requirements for storage conditions and space, and is convenient for replacing damaged parts at any time.

[0005] The technical solution adopted by the utility model to solve the above technical problem is to provide a detachable modular lamination frame, which includes four right-angle connection modules and at least four main frame modules. Grooves are provided at both ends of the right-angle connection module and the main frame module. The right-angle connection module and the main frame module are connected by frame connection blocks, and adjacent two main frame modules are connected by frame connection blocks. The two ends of the frame connection block extend into the grooves of the right-angle connection module or the main frame module and are fixed by flat head screws.
