Description

The invention relates to the manufacture of electronic products and can be used in technological equipment for monitoring and sorting semiconductor devices, boards, such as microcircuits. A device for sorting semiconductor devices, a semiconductor device feeding mechanism from cassettes, a semiconductor device sorting unit, and a semiconductor device loading mechanism into cassettes 1 are known. The disadvantage is that the known device does not automatically change cassettes in the feeding and loading mechanisms semiconductor. devices in cassettes, and also requires frequent cassette changes due to the small cassette capacity, which reduces the sorting performance of semiconductor devices. The closest to the present invention is a device for sorting semiconductor devices, which contains a mechanism for feeding semiconductor devices and a cassette, a sorting unit for semiconductor devices, and mechanisms for loading semiconductor devices into cassettes, and the feeding mechanism and loading mechanisms are designed with cassette guiding means. on rails 2il. This device allows the use of larger-capacity cassettes, but requires separate loading of the cassettes into the semiconductor feeding mechanism and mechanisms for loading semiconductor devices, and the cassettes are loaded at irregular intervals of random size, which requires the constant presence of the operator and reduces the sorting performance semiconductor devices. The purpose of the invention is to increase productivity in work. This goal is achieved by the fact that a device for sorting semiconductor devices, containing a semiconductor device feeding mechanism from cassettes, a semiconductor device sorting unit, and semiconductor device loading mechanisms into cassettes, the feeding mechanisms and loading mechanism being made with guides and means for moving the cassettes in directions gutter, provided with a chute and stops for the cash register, the gutter being installed under the guides of the semiconductor device feeder and zigzag-shaped Form with windows for cassettes located opposite the cassette guides for NuaxaHH3MOB cassette loading semiconductor devices, the groove surfaces located opposite the cassette windows are inclined towards the windows, and the cassette supports are mounted above the cassette guides facing the windows at a distance of shorter cassette lengths. FIG. 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in fig. 3 - BB in FIG. 1. The device contains a semiconductor device feeding mechanism 1 of multi-cassette 2, located in the upper part of the frame, which is made with guides 3 for cassettes 2 and means 4 for moving the cassettes along guides, the semiconductor device feeding mechanism 1 also contains ejecting semiconductor devices from the streams of the cassette 2, and a mechanism for loading the cassettes from the foot onto the guides 3. The block 6 for sorting semiconductor devices is connected to the mechanism for 1 seismic semiconductor supply by tray 7 for instruments and contains mechanisms for transporting and connecting semiconductor devices to a measuring unit. The device also contains mechanisms 8 for loading semiconductor devices into cassettes 2, the number of which corresponds to the number of devices sorting groups. Mechanisms 8 for the loading of electrically conductive devices are installed on a frame at different heights under the mechanism for feeding semiconductor devices from cassettes and a unit 6 for sorting devices and are connected to a unit 6 for sorting by trays 9 and 10 for semiconductor devices. and are made with guides 11 and. means for moving the cassettes along the guides 11 (not shown /. For transporting empty cassettes 2 of the semiconductor device feeding mechanism 1 to the semiconductor device loading mechanisms 8, a groove 12 is installed under the guides of the fur 3; the semiconductor device bottom 1 is zigzag-shaped , with windows 13 for cassettes located opposite guides 11 of mechanism 8 for loading semiconductor devices, g surfaces 14 of trough 12 are inclined toward windows 13. For fixing cassettes 2 rel respect to the guide mechanisms 11 8 semiconductor devices and load chute device 12 is provided with stops 15 for cassettes uStanoylennyh over naprggvl yuschimi 11 opposite the windows 13, at a distance less than the length of the tape. This arrangement permits the abutments 15 to fix the cassette 2 of the cassette protrudes from the

windows 13 in the groove 12. In the guides 3 for the cassettes of the mechanism for feeding semiconductor devices above the yellow boom 12 there is a cut-out 16 for the cassettes. Above the guides 11, strips 17 are installed to secure the cassette 2.

In addition, the device contains mechanisms 18 for stacking e-cassette cassettes from guides 11 mechanisms for loading semi-navigation devices (not shown).

The device works as follows; in a way.

The cassettes 2 are separated from the foot and laid on the guides 3 of the semiconductor device feeding mechanism 1.

The cassette means 4 is moved by a step equal to the distance between the strands of the cassette 2 and after the movement of each handle of the cassette by the mechanism 5, the semiconductor devices are pushed out of the cassette and along the tray 7 are moved to the semiconductor sorting unit 6, according to the measurement results from b block sorting, semiconductor devices by trays 9 or. 10 are fed to one of the mechanisms 8 for loading semiconductor devices into cassettes which, as their streams are filled, move a step equal to the distance between them by means of moving the cassettes along the guide- 11. Initially, before the empty cassettes 2 arrive from mechanism 1 for feeding semiconductor devices, devices are loaded into cassettes 2 in mechanisms 8 to load the remaining after the screening of the previous batch of devices.

As the semiconductor devices of the cassette 2 unloaded in the 3 directions of the semiconductor supply mechanism 1, the cassette is moved by means of 4 for moving the cassettes to the cut 16 of the guides 3. And after the cassette is completely unloaded, it is under the force of gravity feeds through the cutout 16 into the groove 12 and over the surfaces 14 of the groove 12 is fed into the windows 13 and through the windows 13 enters the guides 11 of one of the mechanisms 8 for loading semiconductor devices, if there is still an unloaded cartridge in the guides 11, then the trace The cassette tape is fixed above it by the stop 15 and the strips 17. If two cassettes are in the cassette loading mechanism 8, the next cassette moves along the groove 11 of the second cassette and slides down to the other (lower) mechanism 8 to load the semiconductor devices. As the cassette is loaded in mechanisms 8 for loading semiconductor devices, the lower cassette is displaced relative to the strips 17 and the upper cassette takes its place. Thus, along chute 12. The empty cassettes 2 are transported to the guideways 11 of the mechanisms 8 for loading semiconductor devices into the cassettes, i.e. the number of cassettes loaded with semiconductor devices in loading mechanisms 8 is equal to the number of unloaded cassettes in feed mechanisms .1, semiconductor devices.

If the device is turned on for the first time, then before starting work it is necessary to load several empty cassettes through the chute 12, then the cassettes are loaded automatically. .

The proposed device allows improving the sorting performance of semiconductor devices by automatically feeding cassettes into mechanisms for loading semiconductor devices.
