Abstract
The utility model is related to LED chip production technical field, and especially a kind of LED grain selects special wand.A kind of LED grain selects special wand, including wand body, the wand body is hollow reducing pipe, the stage casing diameter of wand body is more than the diameter of end segments, the front and rear portions in stage casing are respectively provided with step surface, and one end of wand body is connected with vacuum hose, and the other end of wand body is connected with the wand syringe needle of circular tube shaped, the needle tip of the wand syringe needle has two sections of circular arcs, and the angle of the circular arc is 40 °~60 °.Compared to straight barrel type wand, wand body of the present utility model is hollow reducer pipe, is conveniently affectedly bashful；The needle tip of wand syringe needle has two sections of circular arcs, is easier when provoking the chip being bonded on blue film, more time saving, can improve the operating efficiency that chip picks 30%.
Description
Technical field
The utility model is related to LED chip production technical field, and especially a kind of LED grain selects special wand.
Background technology
In flip LED chips production, crystal grain sorting is arranged on blue film after completion, also needs Manual Visual Inspection, and with very
Suction pen chooses the crystal grain of abnormal appearance and malalignment.Wand is straight barrel type structure in original technique, as shown in figure 1, inhaling
One end connection vavuum pump, the other end is wand syringe needle, and the needle tip of wand syringe needle is flat side, operating efficiency when provoking chip
It is low, therefore need to improve the efficiency for picking crystal grain by changing the structure of wand and wand syringe needle.
Utility model content
The technical problems to be solved in the utility model is：Dedicated suction is selected there is provided a kind of LED grain based on above mentioned problem
Pen.
The utility model solves the technical scheme that its technical problem used：A kind of LED grain selects special wand, bag
Wand body is included, the wand body is hollow reducing pipe, and the stage casing diameter of wand body is more than the diameter of end segments, stage casing
Front and rear portions be respectively provided with step surface, one end of wand body is connected with vacuum hose, and the other end of wand body is connected with pipe
The wand syringe needle of shape, the needle tip of the wand syringe needle has two sections of circular arcs, and the angle of the circular arc is 40 °~60 °.
Further, the tail end of the wand syringe needle has the connector being connected with wand body, and the connector is with inhaling
Syringe needle is structure as a whole.
Further, the wand body uses stainless steel.
Further, the wand syringe needle is stainless steel syringe needle.
The beneficial effects of the utility model are：Compared to straight barrel type wand, wand body of the present utility model is hollow reducing
Pipe, is conveniently affectedly bashful；The needle tip of wand syringe needle has two sections of circular arcs, is easier, more saves when provoking the chip being bonded on blue film
When, the operating efficiency that chip picks 30% can be improved.
Brief description of the drawings
The utility model is further illustrated with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation that LED grain selects wand in the prior art.
Fig. 2 is structural representation of the present utility model.
In figure：1. wand body, 2. vacuum hoses, 3. wand syringe needles, 11. stage casings, 12. end segments, 13. step surfaces, 31.
Circular arc, 32. connectors.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
As shown in Fig. 2 a kind of LED grain selects special wand, including wand body 1, wand body 1 is justified for hollow reducing
Pipe, the diameter of stage casing 11 of wand body 1 is more than the diameter of end segments 12, and the front and rear portions in stage casing 11 are respectively provided with step surface 13, wand
One end of body 1 is connected with vacuum hose 2, and the other end of wand body 1 is connected with the wand syringe needle 3 of circular tube shaped, wand syringe needle 3
Needle tip there are two sections of circular arcs 31, the angle of circular arc 31 is 40 °~60 °, preferably, the angle of circular arc 31 is 55 °.
Using such scheme, the tail end of wand syringe needle 3 has a connector 32 be connected with wand body 1, connector 32 and
Wand syringe needle 3 is structure as a whole.
Using such scheme, wand body 1 uses stainless steel, can improve the service life of wand body 1.
Using such scheme, wand syringe needle 3 is stainless steel syringe needle, can improve the service life of wand syringe needle 3.Wand syringe needle
3 needle tip has two sections of circular arcs 31, is easier when provoking the chip being bonded on blue film, more time saving, can improve chip and choose
Pick 30% operating efficiency.
Using it is above-mentioned according to desirable embodiment of the present utility model as enlightenment, pass through above-mentioned description, related work people
Member can carry out various changes and amendments in the range of without departing from this utility model technological thought completely.This reality
The content on specification is not limited to new technical scope, it is necessary to its technology is determined according to right
Property scope.
