Description

Technical Field

[0001] The invention belongs to the field of composite material processing and manufacturing, and in particular relates to an automated production line for photovoltaic composite material frames. Background Art

[0002] Photovoltaic composite frame is a frame structure material used to fix, seal and protect photovoltaic modules. It is composed of glass fiber, polyurethane and fluorocarbon coating. Compared with traditional aluminum alloy frames, photovoltaic composite frames have the advantages of low cost, strong weather resistance, insulation, light weight and beautiful appearance.

[0003] The composite frame has good resistance to moisture, heat, acid, alkali, salt spray, etc., and is suitable for various harsh environments, such as offshore photovoltaics, desert photovoltaics, etc. The composite frame is also sprayed with fluorocarbon paint to increase its anti-ultraviolet and anti-aging capabilities.

[0004] The composite frame has no galvanic corrosion and will not cause problems such as current leakage or potential difference induced degradation (PID), which improves the safety and reliability of system operation and maintenance. The composite frame system does not require grounding, which simplifies the installation process and cost.

[0005] The density of the composite frame is about 22% lower than that of the aluminum alloy frame, making it lighter and easier to transport and install.

[0006] At the same time, composite frames are available in a variety of colors and shapes, meeting the needs of application scenarios such as building-integrated photovoltaics (BIPV) or building-attached photovoltaics (BAPV) that require aesthetics.

[0007] The existing production process of composite frame is mainly pultrusion process. Pultrusion is a process that mixes polyurethane resin and glass fiber, and then forms a continuous profile with the required cross-sectional shape through heating, extrusion and cooling. The advantage of pultrusion is that it can produce high-strength, high-rigidity and high-precision frames.

[0008] Of course, photovoltaic composite material frames still have problems such as low technical maturity and lack of existing automated production lines. As a new type of material, photovoltaic composite material frames are still in the third-party certification and customer introduction stage and have not yet formed large-scale production and application.

[0009] Therefore, how to realize the modern production of composite material frames, improve the production efficiency of composite material frames, reduce the manufacturing cost and make them suitable for mass production is a technical problem that needs to be solved in modern manufacturing. Summary of the invention

[0010] The purpose of the present invention is to solve the deficiencies in the prior art and to provide an automated production line for photovoltaic composite material frames that can overcome the above-mentioned problems.

[0011] In order to solve the above technical problems, the technical method adopted by the present invention is as follows: the present invention discloses an automated production line for photovoltaic composite material frames, including a frame pultrusion production line, a semi-finished product processing production line, and an AGV robot charging area, a fiber raw material placement area, a resin reactor placement area, and a resin raw material placement area;

[0012] The semi-finished product processing production line includes an automated stacking area where workstations are arranged in sequence, a three-dimensional warehouse, a sawing center, a cutting buffer area, a machining center, a surface treatment area, a spraying production line, and a corner code installation area.

[0013] Furthermore, the frame pultrusion production line includes a fiber constant humidity zone and constant temperature zones arranged on both sides of the fiber constant humidity zone.

[0014] Furthermore, the frame pultrusion production line includes a yarn frame, a felt frame, a traction machine, a cutting machine and a straightness detector which are sequentially arranged at the workstations.

[0015] Furthermore, the creel includes a carbon fiber creel and a glass fiber creel.

[0016] Furthermore, the tractor is a double-traction double-output crawler tractor.

[0017] Furthermore, the cutting machine is a double-head ascending cutting machine, including a variable frequency motor and a high-strength steel saw blade.

[0018] Furthermore, the surface of the saw blade is sprayed with corundum.

[0019] Furthermore, the AGV robot charging area includes an AGV transfer robot and an AGV transfer robot charging pile.

[0020] Furthermore, it also includes an automatic packaging area for finished products.

[0021] Furthermore, the sawing center includes an automatic loading and unloading workbench and a robot for supplying materials to the automatic loading and unloading workbench. Beneficial Effects

[0022] Compared with the prior art, the present invention systematically transforms the frame pultrusion production line, adds a semi-finished product processing production line and an AGV robot charging area, a fiber raw material placement area, a resin reactor placement area, and a resin raw material placement area. By completing the transfer of each production station through the AGV robot, the intelligent production of photovoltaic composite material frames can be realized, solving the current integrated manufacturing of photovoltaic composite material frame blanks, semi-finished products, and finished products. At the same time, compared with the separate processing in the existing separate manufacturing and processing workshop, the photovoltaic composite material frame automated production line proposed by the present invention occupies a smaller area and has a higher site utilization rate.
