Description
[technical field]
The present invention relates to a kind of LED encapsulation anchor clamps, refer in particular to a kind of anchor clamps that are used to make the LED silica-gel lens.
[background technology]
High-power LED illumination is energy-conservation with it, environmental protection, advantage that volume is little have begun to substitute traditional lighting source gradually; Led light source need carry out Reflow Soldering in integrated carrying out modularization; The temperature of Reflow Soldering is very high, and general PC lens can't adapt to the calcination of high temperature.People began to attempt adopting resistant to elevated temperatures silica gel to make the lens of LED afterwards, can not be through the technical problem of Reflow Soldering with this great power LED that solves employing PC material lens.
The processing and fabricating mode of the present industry of silica-gel lens has two kinds, and a kind of is that manual reverse mould is made, and promptly manual pick is made silica-gel lens with the reverse mould method for making; Another kind is to adopt full automatic silica gel casting (moulding) forming machine.Moulding machine acquisition cost is high, need the personnel of specialty to debug for a long time and can go into operation, and the stability of product is not high, and each switchgear all needs preheating and adjustment parameters, is not suitable for the production of many specifications, small lot.Obviously manually the convenience of encapsulation with and cheaply advantage under the overall background of current automated production, still occupy a tiny space.
Make LED silica-gel lens anchor clamps on the existing market; In its pressing process the panel of top board and lower platen directly with the support bar on led support and mould bar contact; Because the middle space that does not have buffering; Final lens products is owing to bad phenomenon such as coming off, break appear in unbalance stress, also causes the product glue that overflows simultaneously easily.In order to solve the technological deficiency of being brought that above-mentioned anchor clamps clamp owing to pure rigidity; The Chinese patent notification number is that the patent of CN201478343 discloses a kind of encapsulation anchor clamps that adopt the elastic buffer member, comprises the anchor clamps of being made up of top board and lower platen, and top board and lower platen are connected through the hinge and can fasten clamping; Place mould bar and support bar between top board and the lower platen from the bottom to top successively; Be furnished with hemispherical plastic cement mould grain with grid configuration on the mould bloom, the mould grain is nested in the nib of lower platen, and led support is arranged on the support bar with grid configuration; Its position is corresponding with the mould grain; Top board and lower platen are high temperature resistant hard material and process, and corresponding led support position is provided with storage tank on the top board, are provided with the buffer component that makes led support and the stressed mitigation of mould bar mould grain in the storage tank; The lower platen inner face is provided with groove in the nib outward flange around this nib.This pressing structure makes led support and the stressed mitigation of mould bar mould grain even, is difficult for dislocation, reaches the purpose of clamping, and mould grain difficult drop-off behind the high-temperature baking, breaks, and also can not cause the product glue that overflows.But the top board of these anchor clamps and lower platen link together through the hinge form, and clamping will be locked by locking nut.Well-known LED encapsulation workshop is a dust-free workshop, and in order to ensure the dustless grade in encapsulation workshop, each operation that requires LED to encapsulate is avoided the generation of various dust as far as possible, and the processing procedure of silica-gel lens also is like this.But the mode that adopts screw to lock owing to needs in the operation of above-mentioned making silica-gel lens; Must lock with electric screwdriver; Perhaps manually adopt screwdriver to lock, in this process of locking repeatedly, dismantling, between the nut of electric screwdriver head or driver bit and screw since rigidity contact and very easily produce iron filings; Cause the dust pollution in workshop, and the length consuming time that clamps, dismantles.Adopt this locking mode to lock, dismantle screw repeatedly simultaneously, the nut of screw is damaged, must the frequent change clamping screw.Bring inconvenience for thus whole machining process manufacturing process.
[summary of the invention]
To the dust pollution that exists in the aforementioned prior art, clamp technological deficiencies such as dismounting inconvenience, length consuming time, accessory is fragile, the object of the present invention is to provide and a kind ofly avoid dust pollution, clamp convenient disassembly, weak point consuming time, the non-damageable LED silica-gel lens making of accessory anchor clamps.
In order to reach above-mentioned technical purpose; The technological means that the present invention taked is a kind of anchor clamps that are used to make the LED silica-gel lens; Comprise top board and lower platen; Said top board and lower platen are that separate two-piece type divides body structure, place mould bar and support bar between said top board and the lower platen from the bottom to top successively; Said mould bar comprises support plate and is disposed in an evenly spaced relation in a plurality of lens die cavity bodies on the support plate; Offer first mounting groove that matees with said support plate on the said lower platen, be provided with the nib that matees with said a plurality of lens die cavity bodies in said first mounting groove, said support plate is installed in first mounting groove, and said lens die cavity body is embedded in the nib; The corresponding a plurality of lens die cavity bodies of said support bar are laid with the solid brilliant support of a plurality of LED, and said support bar is fixed on the mould bar; Said top board offers second mounting groove over against first mounting groove of lower platen; The solid brilliant support of corresponding a plurality of LED is provided with a plurality of flexible fastening posts in said second mounting groove; The both sides of said second mounting groove are respectively arranged with reference column; The corresponding reference column in the both sides of said first mounting groove offers location hole, and said top board is located on lower platen through reference column and location hole; Said lower platen both sides are hinged with fixedly buckle respectively; The back side of said top board offers and the fixing holddown groove that is complementary of buckle; Said top board and lower platen are clamped in the holddown groove both locking through fixing buckle, and said mould bar and support bar are fixed in first mounting groove through the flexible fastening post.
Technical scheme of the present invention adopts fully independently two-part construction, and through fixedly buckle on the lower platen and the chucking of the holddown groove elasticity on the top board, entire making process does not have dust to produce; Clamping, convenient disassembly; Weak point consuming time, accessory are not fragile, can obviously improve the dustless grade in LED encapsulation workshop; Enhance productivity, reduce production costs.
