Embodiment Construction

[0012] The inspection mechanism related to the present invention will be described in detail with reference to the drawings. Inspection agencies such as figure 1 with figure 2 As shown, it includes an electrode support 1, and a pair of sheet-shaped cantilever electrodes (positive motor and negative electrode) 5 fixed on the horizontal top surface of an insulating block 3 fixed on the electrode support 1 by screws 2 . The cantilever electrode 5 is preferably made of beryllium copper alloy with good elasticity and excellent conductivity, and its interval is the same as Figure 5 The pair of terminals 7 provided at the rear end of the light-emitting diode 6 shown in the example in FIG. The cantilever electrode 5 has a double fork 11, which is rotatably supported on the shaft 10, and the shaft 10 is fixed on the fixing seat 8 by a screw 9, and one side of the double fork is provided for the electrode support 1. A mechanism for rotation adjustment, which includes a protrusion 1...

Abstract

The invention provides a checking mechanism of electronic component classifier, which can be reliably in electrical contact with the terminal of tiny Light-emitting diode (LED). The checking mechanism in the electronic component classifier comprises a couple of elastic foliated cantilever-type electrodes (5) which are fixed at an interval with the terminal (7) of LED (6) on the top surface of theinsulation block (3) fixed on the electrode bracket (1). When the adsorbing end (15) pushes the absorbed LED onto the cantilever-type electrode, the cantilever-type electrode tilts and bends, therefore the edge of the LED terminal is in electrical contact with the cantilever-type electrode under the effect of friction.

Description

technical field [0001] The present invention relates to a sorting machine for inspecting the optical and electrical properties of electronic components, especially tiny light-emitting diodes (LEDs), and classifying the light-emitting diodes according to the same characteristics, and more particularly relates to the inspection mechanism of the sorting machine . Background technique [0002] Generally speaking, in the production of light-emitting diodes, their optical and electrical characteristics are uneven. In the application of mobile phones and small personal computers, multiple light-emitting diodes are often used as light sources in one unit, so the uneven characteristics of light-emitting diodes will affect the quality of products, and it is required to use light-emitting diodes with uniform optical and electrical characteristics. diode. Therefore, the optical and electrical characteristics of the light-emitting diodes are checked using a sorting machine, and the lig...
