Device and method for isolating objects

Abstract

The invention relates to a device (10) used for isolating objects comprising a conveyor (11), a sensor (12), and a vacuum device. The vacuum device can be used to generate the reversible absorbing force on three points (1,2,3)to isolate a first object (10a) to remove the same. The absorbing force of the second point (2) can be reversed into the neutral or the positive pressure. According to the method provided by the invention, the reversible absorbing forces can be applied to the first object (10a) on two points (1,2), and the reversible absorbing force can be applied to the second object (10b) on the third point (3). During the removing of the first object (10a), the absorbing force of the first point (1) can be converted into the neutral force, and the absorbing force of the second point (2) can be converted into the positive pressure. The absorbing force of the first point (1) can be restored, and the absorbing forces of the second point and the third point (2,3) can be converted into the neutral force.

Description

technical field

[0001] This invention relates to apparatus and methods for uniformly isolating three-dimensional objects, and more particularly to the ability to singulate continuously conveyed objects. Background technique

[0002] Many items in industry need to be segregated for removal, especially those items that are shipped in large quantities. For example, electronic components such as integrated circuits need to be singulated for testing, packaging, or assembly. It would be desirable to have an efficient device and method for handling these items, especially those that are fragile.

[0003] There are many types of machines for singulation in the prior art. For example, a device is disclosed in patent document WO2008 / 148866A2, wherein electronic components are transported into the device along a track until the frontmost component to be removed reaches a sliding bracket. A motorized barrier then moves down to isolate the leading-end component from the other componen...

Examples

example

[0068] The following examples will work with Figures 1 to 4f Let's talk about it. Although item 10 can be any number, in figure 1 and Figures 4a-4f The present example shown in is describing a row of articles 10 comprising: a first article 10a located at the front end of the row of articles 10 closest to the receiving position; a second article 10b adjacent to and located at the rear of the first item 10a; and a third item 10c adjacent to and located behind the second item 10b. As used herein, the term "article" refers to any three-dimensional article.

[0069] Example device

[0070] refer to figure 1 , which shows a side view of a preferred embodiment of the device for insulating articles 10 of the present invention. The feeder 11 preferably includes a linear track 15 for feeding the articles 10 in a row to the receiving position. The receiving position is the position on the feeder 11 where the items 10 are to be removed. The linear track 15 and the articles 10 co...
