Description

Plastic tray special for photovoltaic cell assembly

Technical Field

The application belongs to the technical field of plastic trays, and relates to a special plastic tray for photovoltaic cell assemblies.

Background

The packaging and transportation of the photovoltaic modules at home and abroad always adopts a wood tray, and almost no other substitute products exist. The wooden pallet is easy to crack or even break in the use process, so that the photovoltaic module is easy to damage during loading and unloading. The wooden tray is generally disposable, so that the wood dust is frequently removed in the use process, and the iron nails of the wooden tray are easy to rust, unhygienic and unfavorable for dust-free workshops. In addition, the wooden tray is afraid of moisture and is easy to rot during outdoor storage, and meanwhile, a large amount of wood is disposable, so that the wooden tray is not beneficial to low carbon and environmental protection.

The plastic tray is clean and sanitary, can be recycled and has light weight, and is an ideal substitute, but the plastic tray has some research and development difficulties at present. Mainly comprises the following aspects: first, photovoltaic cell assembly plastic pallet, it is with high costs, manufacturing risk is big. Firstly, the price of plastic is generally higher than that of wood, and large injection molding machines, large molds and the like are needed for manufacturing large-size plastic trays, so that the investment and the production cost are large. Secondly, the die Fei Gao is generally about 80-150 ten thousand because of the die for manufacturing the photovoltaic plastic tray. And a set of molds can only be produced in one size, if the photovoltaic module is changed in size, the molds are discarded. Therefore, the risk of manufacturing the tray mold is also very high. Secondly, the plastic tray is relatively soft and is easy to deform under stress. PP or PE is the main material used for plastic trays, but these plastic materials are generally softer than wood, so that plastic tray top plates are easily deformed when subjected to force. When the packing belt is used or hoisted, the stress points are easy to damage. Third, the production efficiency is low. During injection molding production, the production efficiency of the large plastic tray can be reduced due to the influence of factors such as cooling and core pulling. In addition, plastic trays are typically manufactured using molds that once set, are not easily changed in appearance and size, and thus are not suitable for users who require frequent changes in packaging. Fifth, the plastic pallet is smoother than the wood pallet, and is easy to slip during forking.

The light Fu Tuo disk module 1 is of a grid structure as a whole, and adjacent plane ribs forming the grid structure are arranged on the top surface and the bottom surface alternately, and are opposite in orientation, so that the strength of the grid structure can be effectively increased. As can be seen from fig. 3 and 5, the photovoltaic tray module 1 has wings on both sides, namely an upper wing 2 and a lower wing 8, respectively, which are provided at the upper and lower ends of the side fork 9. The upper flying wing 2 is provided with the packing belt opening 3, and the size and the position of the packing belt opening can be adjusted because the packing belt opening 3 can be opened when in use due to the soft plastic structure. For allowing the strap to enter this mouth 3 when it is being wrapped. The flying wings are designed on the periphery of the tray, and the design of the upper flying wing 2 can increase the supporting area of the plastic tray, shorten the span of the fork openings and improve the bearing strength. The lower flying wing 8 of the bottom plate increases the stress area of the tray bottom plate and also increases the strength of the bottom plate. A plurality of studs are arranged below the flying wing to support, so that the strength of the flying wing is improved. Referring to fig. 2 and 3, the light Fu Tuopan module is provided with a flat iron clamping groove 4 which spans over the side piers 5 on two sides, so that flat iron can be arranged in the photovoltaic tray to increase strength. And a flat iron clamping groove can be formed at the upper end or the lower end of the side fork opening so as to increase the strength of the photovoltaic tray module in the direction. The traditional plastic pallet has the advantages that the strength is increased, a steel pipe is added, a steel pipe orifice is designed on a die, but the die core pulling is required to be increased, the process is complex, the production efficiency is reduced, and the cost and the weight of the steel pipe are higher than those of flat iron. In this embodiment, a plurality of protrusions 18 are provided on the upper portion 4 of the flat iron clamping groove to prevent the flat iron from falling off, as shown in fig. 4, the protrusion angles inside the flat iron clamping groove 4 are different, and the protrusions, the grooves and the reverse protrusions are arranged in sequence along the direction of the flat iron clamping groove, so as to facilitate the placement of the flat iron. Fig. 4 shows one of the small projections 18 and grooves, followed by the reverse projections and grooves, and so on. After the flat iron is placed in the clamping groove, the bulges are arranged at the middle upper part of the flat iron clamping groove 4, and the bulge directions are staggered, so that the flat iron can be fixed in the flat iron clamping groove 4 after being placed, and cannot slide out, as shown in fig. 2 and 4. The flat iron clamping groove 4 is designed, so that flat iron can be vertically placed on the tray panel, and the flat iron cannot deform when being stressed. The strength of the tray can be greatly increased by placing the flat iron, and the tray is not easy to bend. As shown in fig. 5, above the middle pier 6, a central reserved opening 11 is designed, injection molding production of plastic trays, core pulling and product cooling are all needed for a long time, and production efficiency is reduced, and the design of the central reserved opening 11 in this embodiment can avoid core pulling design, increase cooling area and improve production efficiency. A plurality of half-through T-shaped grooves 12 and hooking grooves 13 are designed on the upper surface of the central reserved opening 11, and can be matched with an installation end cover 19. The bottom of the half-through T-shaped groove 12 is designed to be in a sealing state, and after the end cover 19 is installed in place, the end cover is fixed at the bottom of the half-through T-shaped groove 12 and cannot move downwards.
