In order to be illustrated more clearly that the embodiment of the present application or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, the accompanying drawing that the following describes is only some embodiments recorded in the application, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.
The structural representation that Fig. 1 show in the specific embodiment of the invention light-collecting lens；
Fig. 2 show in the specific embodiment of the invention support bracket fastened structural representation.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is described in detail, it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, the every other embodiment that those of ordinary skill in the art obtain under the premise not making creative work, broadly fall into the scope of protection of the invention.
Shown in ginseng Fig. 1, light-collecting lens is mainly made up of ultra-thin mirror sheet 1, ultra-thin pressure sensitive adhesive 2, aluminium honeycomb core board component 3 and fixed support 4.
Different according to institute's application apparatus demand, plate face shape can be fabricated to single-curved surface light-collecting lens and hyperboloid light-collecting lens, thus getting linear concentrator band and point focusing tabula rasa.Specific embodiments is that big slot type single-curved surface group and butterfly hyperboloid component are slit into several sectional curve cambered surfaces.Vary in size according to separate unit condenser system watt level and opening radius, single-curved surface or parabolic reflector minute surface component can be segmented into inner panel, middle plate, outside plate.If curved surface opening radius I is to be fabricated to veneer, the bigger divisible inner panel of opening radius and outside plate, opening radius is especially big, may be partitioned into inner panel, middle plate, outside plate.The main making precision of consideration on the one hand provides high, consideration production cost reduction on the other hand, and stock utilization improves.But can not be too little, so can affect the progress that field adjustable is installed, whole engineering is brought bigger human cost.
Ultra-thin mirror sheet 1 is partitioned into some lens units 101 according to the required cross section of individual backboard, concrete partitioning layout is shown in accompanying drawing 1, adopts the silver-plated eyeglass made of float glass process ultra-thin glass to vary in size according to individual Lens assembly backboard and can be partitioned into 4～10 kinds of specifications on a backboard.The best decile of Cutting Length, one be consider attractive in appearance but consider transport with turnover time packing crates specification consistent.The eyeglass of cutting is belonging to super-thin plane glass lens.Selecting ultra-thin purpose is to have good pliability, meets when pasting on the backboard having with certain cambered surface the tension force of glue-line is little, very amiable bonding, does not produce stress concentration phenomenon, lightweight advantage.The purpose selecting flat lens is that silver coating is uniform, production technology is suitable for mass production, the advantage at the bottom of transport, cutting and production cost.Select the purpose of glass lens be silver coating in glass back, not with extraneous contact, effectively protect the aging of silver layer, dislike out of doors slightly under weather simultaneously, especially sand and dust, sleety weather glass can effectively protect the aging of mirror.Having the transparency and certain intensity, the hardness of light owing to float glass belongs to the relatively common plate glass of soda lime glass, its surface smoothness can match in excellence or beauty with mechanical polishing glassy phase.There is higher outdoor adaptive capacity and light transmission.
Ultra-thin pressure sensitive adhesive 2 is current automobile and the glue kind of the relatively broad application of advertising sector.Glue itself out of doors and the environment that variations in temperature is relatively big, ultraviolet is higher ensure that long-term reliable viscosity and ageing resistance.But with this brood lac between ultra-thin mirror sheet 1 and aluminium honeycomb core board component 3 its advantage bonding be that two kinds of glued object board surface quality are smooth, can large area 100% compound, integral vacuum curing process in combination with aluminium honeycomb core board component 3, make the performance of ultra-thin pressure sensitive adhesive 2 to optimum state, it is ensured that overall bonding firmness and persistency.
The production technology of traditional architecture cellular board has been used for reference in the design of aluminium honeycomb core board component 3 and making, but owing to requiring high product for optical accuracy, its inspection and examination aspect have employed unique optical reflection and cameras capture principle obtains accurately accuracy detection.In order to obtain high-precision optical reflection effect, make in cellular board process, first make the shaping dies of a set of consideration springback capacity.Mould is drawn fixing product and took turns boundary line, the panel 301 of aluminium honeycomb core board component 3, central layer 302, backboard 303 are laid on mould after carrying out gluing one by one.Ultra-thin mirror sheet 1 on panel, ultra-thin pressure sensitive adhesive 2 can before aluminium honeycomb core board component is formed on panel fixed bonding.Which enhance industrialization efficiency.Lens quality adopts schematic diagram in accompanying drawing 2 to carry out detection lens quality.
Shown in Fig. 2, fixed support 4 forms and is made up of fixing plate 401, fixing bar 402, fixing locking device 403.Fixing plate structure glue on m is bonded on the backboard 303 of aluminium honeycomb core board component, fixes with pulling rivet simultaneously.Fixing bar 402 packs in fixing plate 401 in advance, it is possible to swings flexibly in fixing plate 401, but can not rotate.Fixing locking device 403 is fixed on the steel construction piece to fix, is be inserted into fixing bar 402 in fixing locking device 403 to be locked when to install aluminum honeycomb panel assembly.Fixing locking device 403 can pass through artificial locking, fixing after debugging also by special automatic jig.It is suitable for production in enormous quantities, installation requirements.
It should be noted that, in this article, the relational terms of such as first and second or the like is used merely to separate an entity or operation with another entity or operating space, and not necessarily requires or imply the relation that there is any this reality between these entities or operation or sequentially.And, term " includes ", " comprising " or its any other variant are intended to comprising of nonexcludability, so that include the process of a series of key element, method, article or equipment not only include those key elements, but also include other key elements being not expressly set out, or also include the key element intrinsic for this process, method, article or equipment.When there is no more restriction, statement " including ... " key element limited, it is not excluded that there is also other identical element in including the process of described key element, method, article or equipment.
The above is only the detailed description of the invention of the application; it should be pointed out that, for those skilled in the art, under the premise without departing from the application principle; can also making some improvements and modifications, these improvements and modifications also should be regarded as the protection domain of the application.
