Abstract

A mounter with an LED optical detection function comprises a suction nozzle and further comprises an optical detector. The suction nozzle comprises a first electrode, a second electrode and an insulating tape which isolates the first electrode from the second electrode, wherein the first electrode and the second electrode make contact with an LED and provide electric power for the LED when the LED to be mounted is picked up by the suction nozzle, and the working state of the LED is detected by the optical detector. In comparison with the traditional steps for mounting an LED, due to the fact that the optical detector is arranged on the suction nozzle of the mounter, optical detection can be conducted on the LED in the mounting process. The mounter with the optical detector is used for mounting the LED, on one hand, the LED testing procedures after the mount is completed are reduced, on the other hand, the light emitting state of the LED can be monitored in the mounting process, and labor cost and time cost are saved. The invention further provides a method for mounting the LED by using the mounter with the LED optical detection function.

Embodiment

Below with reference to the drawings, the present invention is described in further detail.

Please consult Fig. 1 and Fig. 2 simultaneously, show the schematic diagram of two angles of the chip mounter 100 of the LED of having optical detection function of the present invention.Wherein, shown in Fig. 1 be have LED optical detection function chip mounter 100 face cross-sectional schematic, Fig. 2 is the schematic top plan view with chip mounter 100 of LED optical detection function.

This chip mounter 100 comprises a suction nozzle 20 and a fluorescence detector 30.From the depression angle of Fig. 2, this suction nozzle 20 is one or four frame type structures, and it comprises one first electrode 21, one second electrode 22 and two insulating tapes 23.This first electrode 21 and this second electrode 22 are distributed in the opposite end of this four frame type, and connect it by this two insulating tape 23 and form four frame types of seeing from depression angle from beginning to end.Enclosed by this first electrode 21, second electrode 22 and two insulating tapes 23 and to form a vacuum 24 that is positioned in the middle of this suction nozzle 20.The insulating cylinder that this suction nozzle 20 also can be formed in one, its inboard corresponding both sides two conducting strips that separate that are sticked, sheet metal for example is as this first electrode 21 and second electrode 22.This vacuum 24 can produce a suction by utilizing its vacuum state, is used for drawing LED40 to be mounted.Be appreciated that ground, this suction nozzle 20 also can be designed to anchor clamps, namely first electrode 21 and second electrode 22 be for articulating or be movably connected on by other means on two insulating tapes 23, relatively moves to insert and put LED40 to be mounted by this first electrode 21, second electrode 22.This first electrode 21 and second electrode 22 are made by electric conducting material.In the present embodiment, this first electrode 21 and second electrode 22 are made by the copper surface gilding, can effectively strengthen the conduction quality.Fluorescence detector 30 is connected with this suction nozzle 20, and it is positioned at the top of this vacuum 24, between this first electrode 21, second electrode 22 and two insulating tapes 23.This fluorescence detector 30 is attached on the insulating tape 23, and is electrically connected with this first electrode 21, second electrode 22 by lead or other modes.This fluorescence detector 30 is its detection faces 31 towards the surface of this vacuum 24, and namely when light was injected into this detection faces 31,30 pairs of incident raies of this fluorescence detector detected.This fluorescence detector 30 can be arranged to detect the brightness of incident ray and the relative value of comparing brightness as required.If need more high-precision optical detection, also this fluorescence detector 30 can be connected to by optical fiber or other modes and make wavelength analysis on the spectrometer.
