Description

[Detailed description of the invention] [Industrial application field]

The present invention is aimed at the test section in IC Pandora.
This invention relates to a device feeding device for an IC handler that sequentially feeds devices one by one by sliding down the device under its own weight.

[Conventional technology]

The IC handler attaches the IC device to the test head in the test section, tests and measures the operation of the IC device in high- or low-temperature environments, and classifies the IC device according to quality based on the test results and stores it again. It is used for. This IC handler includes a device supply mechanism, a loader-side transport mechanism that separates IC devices supplied from the device supply mechanism one by one and transports them to the test section, and an unloader that transports the tested IC devices to the unloader section. It consists of a side conveyance mechanism. Here, a large number of IC devices are stored in a magazine, and by tilting this magazine, the IC devices are slid down by their own weight from inside the magazine, and are separated one by one and sent to the loader side transport mechanism. There is. For this purpose, a magazine stocker is provided in the device supply section, and a large number of magazines are stored in the magazine stocker in a stacked state. Moreover, in order to reduce the frequency of loading magazines, a magazine stocker is used that is configured to store magazines in a plurality of stacked rows. Conventionally, when storing multiple rows of magazines in a magazine stocker, the magazine is moved forward and downward. A magazine conveying means that performs a rectangular movement consisting of backward and upward movements was used. First, the magazines in each row are separated one by one from the lower end of the magazine stocker and transferred onto the magazine conveying means, and the magazine conveying means is moved in a rectangular manner to move the magazines away from the magazine stocker. By separating only one magazine from the others from the magazine transporting means and sending it to the magazine tilting means, the magazine is clamped by the magazine tilting means, and the magazine is tilted so as to lift its base end. Conventionally, a magazine has been used in which the IC devices in the magazine are slid down by their own weight to be taken out one by one and sent to the loader side transport path. [Problem to be Solved by the Invention] Incidentally, in the prior art device described above, in order to separate the plurality of magazines taken out from the magazine accommodating section one by one, the magazine conveying means has to perform a complicated operation of rectangular movement. Therefore, the configuration of the drive mechanism for the magazine conveying means in the magazine supply mechanism becomes complicated. After ejection of IC devices from the magazine is completed, the magazine tilting means is returned to the horizontal state, the clamping state is released, the empty magazine is ejected, and a new magazine is then positioned and the magazine tilted. It must be mounted on the means and placed in a tilted position. For this reason, it takes a lot of time to replace the magazines. Therefore, if the magazines are clamped and tilted one by one, the frequency of replacing the magazines increases, resulting in a problem that the time required to replace the magazines while the device is in operation becomes longer overall. The present invention has been made in view of the above points, and an object of the present invention is to provide a device supply device for an IC handler that has a simple configuration and can reduce the frequency of magazine replacement. It is about providing. [Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention provides
A magazine stocker that stacks multiple rows of magazines storing devices, and a magazine that clamps the same number of magazines as the number of rows of the magazine stocker and tilts them to allow IC devices to slide down into the chute part by their own weight. with a tilting means, reciprocating in the horizontal direction,

[Effect 1] By adopting such a configuration, multiple magazines supplied from multiple rows of magazine stockers can be tilted by a simple movement of horizontally conveying them, rather than a complicated movement of rectangular movements. The structure of the magazine conveying means for transferring the magazine from the magazine stocker to the magazine tilting means can be significantly simplified. In addition, since multiple magazines are configured to be clamped and tilted at the same time, it is only necessary to replace the magazines with new ones when all of the multiple magazines clamped by the magazine tilting means are empty. Therefore, the frequency of replacing the magazine is reduced, and the overall IC device supply time can be shortened.
