Abstract

The utility model discloses a crystalline grain packaging took and relates to a tool for finishing and packaging sorted chips in semiconductor chip processing, which can regularly arranging scattered crystalline grains in grooves and packaging the chips in a regulated state. The tool comprises a base plate, a lining plate and a sucking disc, wherein the horizontal cross section of the base plate is rectangular, raised frame bars are arranged on three edges of the base plate and the plate surface of the base plate among the raised frame bars forms a lining plate accommodating groove, and positioning pins are arranged on the opposite raised frame bars; a plurality of crystalline grain accommodating grooves are formed on the lining plate; the lining plate is positioned in the lining plate accommodating groove on the base plate with the crystalline grain accommodating grooves on the lining plate facing the ground; the disc surface of the sucking disc is provided with a plurality of crystalline grain sucking grooves, the sucking disc is provided with positioning pin holes corresponding to the positioning pins on the base plate, and the plurality of crystalline grain sucking grooves correspond to the crystalline grain accommodating grooves one by one; and negative pressure air duct is formed in the sucking disc, and the plurality of crystalline grain sucking grooves are communicated with the negative pressure air duct. In the utility model, in the whole process from scattered products to packaged products, the collision and extrusion among crystalline grains are prevented so as to avoid corner defects of crystalline grains, the number of the crystalline grains can be calculated accurately, and thus, the requirements of customers can be met.

Description

The crystal grain wrapping tool

Technical field

The utility model relates to the instrument that in the semiconductor wafer processing wafer is sorted back consolidation, packing.

Technical background

In semicon industry, often occur the situation of crystal grain according to different voltage class classification, need be when perhaps the packing requirements of customer requirement crystal grain employing lining dish packing or encapsulation bridge are right with crystal grain according to predetermined station, same angle, same face are put.Mostly adopt sucker screening crystal grain, play branch to the fixing purpose of crystal grain.

The application of crystal grain packing, the production scene is adopted plastic bottle packing crystal grain mostly, fills up cotton in the bottle and prevents that intercrystalline from rocking collision.But for big crystal grain, intercrystalline extruding still can cause phenomenons such as crystal grain unfilled corner.And adopt the method for crystal grain coefficient conversion, approximately calculate the quantity of crystal grain, tend to receive that the few visitor of quantity tells report.At this moment, have a kind of can accurate Calculation crystal grain quantity and can eliminate the crystal grain collision and the packing method of unfilled corner seems particularly important.

The utility model content

The utility model provides a kind of and crystal grain at random fitly " can have been returned groove " at above problem, and the crystal grain wrapping tool of packing under the consolidation state.

The technical solution of the utility model is: it comprises chassis, lining dish and sucker;

The horizontal section on described chassis is rectangular, and three limits on chassis are provided with protruding moulding, and the chassis card between the protruding moulding is a lining dish accommodating groove, is provided with positioning pin column on relative protruding moulding;

Described lining dish is provided with some crystal grain accommodating grooves, and the crystal grain accommodating groove places towards ground on the chassis in the lining dish accommodating groove on the described lining dish;

Described sucker card is provided with some crystal grain absorption cells, and the positioning pin column on the corresponding described chassis of described sucker is provided with dowel hole, makes described some crystal grain absorption cells corresponding one by one with the position of described crystal grain accommodating groove; Also be provided with the negative pressure air flue in the described sucker, described some crystal grain absorption cells are connected with described negative pressure air flue.

Four limits that described sucker is provided with are provided with moulding, and one of them moulding is provided with breach, are convenient to unnecessary crystal grain and discharge.

Sucker of the present utility model can with crystal grain consolidation at random collect, to receive the sucker of receiving crystal grain again, tip upside down on the chassis that accommodates the lining dish with facing down, close negative pressure, crystal grain falls into the accommodating groove on the lining dish under the effect of deadweight, shift out from one side (not having protruding moulding) of chassis upper shed again, carry out pile, promptly finish packing.The utility model is finished to packing from product at random, and overall process avoids intercrystalline collision extruding to cause crystal grain unfilled corner and energy accurate Calculation crystal grain quantity, thereby satisfies customer requirement.

The specific embodiment

The utility model is shown in Fig. 1-4, and it comprises chassis 1, lining dish 2 and sucker 3;

The horizontal section on described chassis 1 is rectangular, and three limits on chassis 1 are provided with protruding moulding 10, and the chassis card between the protruding moulding 10 is a lining dish accommodating groove 11, is provided with positioning pin column 12 on relative protruding moulding 10;

Described lining dish 2 is provided with some crystal grain accommodating grooves 22, and crystal grain accommodating groove 22 places towards ground on the chassis 1 in the lining dish accommodating groove 11 on the described lining dish 2; Cautious for ease of final products, the area relationship between lining dish 2 and the lining dish accommodating groove 11 can be selected as required, as being 2 * 3 selection mode, also can be 3 * 3,2 * 2,2 * 4 etc. among Fig. 2.

Described sucker 3 cards (driving surface 31) are provided with some crystal grain absorption cells 332, and described sucker 3 corresponding described The One On The Chassis positioning pin columns 12 are provided with dowel hole 32, make described some crystal grain absorption cells 332 corresponding one by one with the position of described crystal grain accommodating groove 22; Also be provided with negative pressure air flue 35 in the described sucker 3, described some crystal grain absorption cells 332 are connected by bottom land pore 331 with described negative pressure air flue 35.

Four limits that described sucker 3 is provided with are provided with moulding 30, and one of them moulding 30 is provided with breach 34, are convenient to unnecessary crystal grain 4 and discharge.

For ease of the location, can sucker unit 33 be set according to the proportion relation between aforementioned lining dish 2 and the lining dish accommodating groove 11 on the sucker 3, receive groove 332 to be located on the sucker unit 33.
