Description

A kind of rack of the iron hoop for carrying LED wafer

Technical field

This utility model relates to LED chip production technical field, in particular it relates to a kind of ferrum for carrying LED wafer The rack of ring.

Background technology

At present, domestic LED industry is the trend of fast development, and market the most gradually moves to maturity, and it mainly shows as LED The price of product is more and more lower, performance is become better and better, it is the most increasing to compete, and each large chip producer is all expanding the scale of production, Increase shipment amount, reduce cost by the advantage of scale and then seize the market share.In the second half section of chip production, need to use A kind of circular iron hoop, as carrying tool, will have sticking tunica albuginea and cover on iron hoop and by solid with tunica albuginea bonding for bulk wafer Fixed, move wafer by mobile iron hoop to carry out the operations such as follow-up cutting, splitting, owing to the tunica albuginea used is once Property, each iron hoop could again be covered with new film after must spending within least 2-3 hour, removed by old film and put into next time Use, remove the iron hoop after old film and be packed together stand-by.Along with the increase of yield, the iron hoop quantity that needs are used also can phase Should increase, substantial amounts of iron hoop is piled up and be there is the problem that floor space is big, transport difficulty, and is also easy in above process Occur colliding with, wearing and tearing and the situation of crimp, cause the increase of production cost, affect the production of wafer.

Utility model content

For overcoming the technical problem that above-mentioned iron hoop transport difficulty is big, deposit inconvenience, a kind of simple in construction of this utility model offer, It is easy to deposit and transport the rack of the iron hoop for carrying LED wafer.

The rack of a kind of iron hoop for carrying LED wafer, including cylindrical base, multiple is arranged under described base The universal wheel of bottom surface and the many location round bars being vertically installed in described base upper bottom surface, described location round bar sets equably Put in same circular lines, for insert iron hoop inside and with its inner ring clamping, the middle part of described location round bar also sets up There is height adjustment knob, the length of described location round bar can be regulated according to the particular number of placed iron hoop, it is simple to iron hoop Take out and be inserted in.

Described iron hoop produces for coordinating, and its profile and size are fixed, and its thickness is 1.2mm, and inner ring is the circle of radius 97mm, Outer ring is 114mm with the maximum distance in the center of circle, so the radius of described base is 120～130mm, and its height is 100～200mm.

In order to alleviate weight and be easy to stretch, described location round bar is hollow-core construction, and its radius is 10mm, and greatest length is 800～1200mm.

According to a preferred embodiment of the present utility model, the inside of described base hollows out and is filled with sand, both saved Material and cost, in turn ensure that steadily of centre of gravity.

According to a preferred embodiment of the present utility model, the quantity of described location round bar is four.

According to a preferred embodiment of the present utility model, the quantity of described universal wheel is four.

According to a preferred embodiment of the present utility model, the material of described rack is rustless steel.

The technical scheme that this utility model provides has the advantages that described rack has simple in construction, easy to use Feature, can make iron hoop deposit and transport becomes orderly, simple, also effectively prevent colliding with, wear and tear and squeezing between iron hoop The smooth production of the situations such as compressive strain, beneficially wafer.

Accompanying drawing explanation

In order to be illustrated more clearly that the technical scheme in this utility model embodiment, in embodiment being described below required for make Accompanying drawing be briefly described, it should be apparent that, drawings discussed below is only embodiments more of the present utility model, For those of ordinary skill in the art, on the premise of not paying creative work, it is also possible to obtain according to these accompanying drawings Other accompanying drawing, wherein:

Fig. 1 is the side structure schematic diagram of this utility model preferred embodiment；

Fig. 2 is the schematic top plan view of embodiment illustrated in fig. 1；

In figure: 01 iron hoop, 1 base, 2 universal wheels, 3 location round bars, 4 height adjustment knob.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is carried out clearly Chu, it is fully described by, it is clear that described embodiment is only a part of embodiment of the present utility model rather than whole Embodiment.Based on the embodiment in this utility model, those of ordinary skill in the art are not under making creative work premise The all other embodiments obtained, broadly fall into the scope of this utility model protection.

Seeing Fig. 1 and Fig. 2, the rack of a kind of iron hoop for carrying LED wafer, its material is rustless steel, including circle The base of cylindricality 1, four be uniformly arranged on the universal wheel 2 of described base 1 bottom surface and four be vertically installed in described The location round bar 3 of base 1 upper bottom surface, described location round bar 3 is evenly provided in same circular lines and symmetrical two-by-two, For insert iron hoop 01 inside and with its inner ring clamping, the middle part of described location round bar 4 is additionally provided with for regulating it The height adjustment knob 4 of body length.

The inside of described base 1 hollows out and is filled with sand, has both saved material and cost, in turn ensure that steadily of centre of gravity. In the present embodiment, the height of described base 1 be 150mm, radius be 122.5mm.

Described location round bar 3 is hollow-core construction, and in the present embodiment, and the radius of described location round bar 3 is 10mm, Long length is 1000mm, and the distance between its center of circle and described base 1 center of circle is 85mm so that described iron hoop 01 is being placed Time and described location round bar 3 between gap only have 2mm, play fixed position, prevent the effect collided with.

The foregoing is only preferred embodiment of the present utility model, not thereby limit scope of patent protection of the present utility model, For a person skilled in the art, this utility model can have various modifications and variations.In spirit of the present utility model and Within principle, every any improvement utilizing this utility model description and accompanying drawing content to be made or equivalent, directly or Connect and be used in other relevant technical field, all should be included in scope of patent protection of the present utility model.
