Sorting machine and sorting method suitable for IC chip conveying device

Abstract

The invention discloses a sorting machine suitable for an IC chip conveying device, and the sorting machine comprises a feeding opening, a qualified material opening and a waste material opening, andfurther comprises a sorting area and a sorting block capable of containing IC chips. In the vertical direction of the sorting area, the sorting area, the feeding opening and the qualified material opening are located on the same track; the sorting area is communicated with a waste port in the horizontal direction; the sorting block can convey the IC chips from the sorting area to the waste material opening; and the qualified material opening is perpendicular to the blanking direction of the waste material opening. An existing IC chip conveying mode is changed, a material receiving table is removed, and the feeding opening and the qualified material opening are formed in the same track, so qualified IC chips can directly enter a material pipe through the qualified material opening, and theconveying efficiency is high; the qualified material opening is perpendicular to the blanking direction of the waste material opening, so the IC chips in the sorting area can be directly dragged to the waste material opening by directly adopting the sorting block; the whole separation process only needs the separation block to complete one-time action, and is efficient and convenient.

Description

technical field [0001] The invention relates to the field of IC chip manufacturing equipment, in particular to a sorting machine suitable for an IC chip conveying device. Background technique [0002] IC chip (Integrated Circuit Chip) is an integrated circuit formed by placing a large number of microelectronic components (transistors, resistors, capacitors, etc.) on a plastic base to make a chip. Integrated circuit (IC) chips must undergo strict testing after the packaging process to ensure product quality. [0003] In the existing IC chip detection, it is necessary to take out the chips in the material tube one by one for testing during the test, and then put the IC chip into the empty material tube after the test is completed. [0004] For example, the application number is: 201910012099.X, and the application name is: the patent application for automatic IC testing and sorting equipment. It can be seen that the action of the material receiving table is: after the IC chip...

Problems solved by technology

[0005] However, because the qualified rate of existing IC chips is much greater than the defective rate, the process of connecting the discharge end of the material receiving platform with the first material receiving mechanism by sliding each time will cause a loss of man-hours and affect the efficiency of production testing.

[0006] Secondly, the existing sorting machines suitable for IC chip conveying devices are all driven by servo motors and belts are used to transmit torque, so the mechanical utilization rate is low; Aging failure is very easy to occur, and the product replacement cycle is short; secondly, when the out-of-step problem occurs between the motor and the belt, it will directly cause the channel between the receiving end and the receiving mechanism to fail to align, resulting in transmission failure
