Sorter pick-and-place device

Abstract

A pick-and-place device for a sorter includes a tray to be sorted and a tray to be sorted that move along a first direction and a second direction respectively, the sorted tray is arranged at intervals from the tray to be sorted along the first direction, and a pick-and-place arm set It is arranged in the middle of the tray to be sorted and the sorted tray along the first direction. The pick-and-place arm group includes two pick-and-place arms arranged at 180 degrees apart from each other. The placing arm is positioned above the sorted tray to place semiconductor components synchronously, effectively improving the efficiency of picking and placing semiconductor components.

Description

technical field [0001] The invention relates to a sorting machine for semiconductor components, in particular to a pick-and-place device for the sorting machine. Background technique [0002] refer to figure 1 , figure 2 and image 3 , a semiconductor component sorting machine 1 in the past, including a tray 11 to be sorted, a tray 12 that has been sorted, and a pick-and-place arm 13. Moving in a second direction Y, a wafer 14 is placed on the tray 11 to be sorted, and a plurality of semiconductor elements 15 are separated on the wafer 14, and the pick-and-place arm 13 is adjacent to the tray 11 to be sorted and the tray 12 that has been sorted Set, the pick-and-place arm 13 moves up and down along a third direction Z, the pick-and-place arm 13 is used to absorb the semiconductor element 15 that has passed the test on the tray 11 to be sorted, and rotates to the top of the sorted tray 12, and will pass through The inspected semiconductor element 15 is placed on the sort...

AI Technical Summary

Problems solved by technology

[0003] When the size of the wafer becomes larger, the length specification of the pick-and-place arm 13 must be lengthened to have enough freedom to rotate, and the setting position of the pick-and-place arm 13 must be further away from the to-be-sorted tray 11 and the sorted tray 12 , causing the disadvantage of increasing the overall volume of the sorter 1

[0004] In addition, the sorter 1 can only move one semiconductor element 15 at a time, and must stop when picking up and placing. Although the rotation angle is less than 180 degrees, the rotation speed of the pick-and-place arm 13 cannot be increased during the rotation. The aforementioned reasons are all The problem that the classification time increases and the classification efficiency cannot be improved
