Definitions
- the present invention relates to a device for putting in storage element of slices of a sawn block attached by a heel to a cutting support (see e.g. JP-A-06-039 831).
- the block to be cut is generally mounted glued on a plate intended for use unique, if possible a material with characteristics approaching the material to be cut.
- This plate is mechanically mounted on a second support cutting which serves as a link with the cutting machine.
- the block of material will be cut completely and the cutting tool will open into the operating plate unique.
- the block will appear as a set of separate parallel slices from each other by the saw cut but attached at their base by a partially cut heel and always part of the single use plate mounted on a cutting support. It will then be necessary to separate the slices of the single use plate.
- the use of the slices thus obtained requires keep them separate and put them in items storage often called cassettes for processing subsequent such as for example washing, polishing or simply removing the remnants of glue.
- the setting up manual storage is long and tedious with in addition significant risks of breakage.
- the object of the present invention is to remedy to the aforementioned drawbacks and the device according to the invention is characterized, for this purpose, by the fact that it comprises a cutting mechanism comprising a cutting tool arranged to cut out said heel and a member displacement likely to produce relative displacement between all of the slices and the cutting tool to present the slices one by one to the cutting tool and to detach the slices one by one from the heel, and a recovery mechanism arranged to resume each detached slice and place it in an empty box of the storage element.
- the setting operation storage item is made easier and faster, reliable and streamlined. Slices, even thick very reduced, can be treated easily and without risk of being damaged.
- the operating device slice by slice is better suited and offers better performance, increased productivity and superior reliability.
- the device comprises a single use plate on which the block is fixed and which is mounted on the cutting support and the cutting mechanism is arranged to cut said heel or single use plate according to a direction substantially perpendicular to the edges for separate them one by one from the heel.
- the recovery mechanism comprises a conveyor belt for transferring the wafers separated from the heel towards the storage element.
- the device comprises an installation with one or more nozzles intended inject a pressurized fluid to facilitate detachment of the released tranche.
- the device for placing in cassette attached slices by a heel to a cutting support, object of the present invention therefore includes a table on which is fixed the cutting support with its cut block and stuck on the single use plate, a mechanism cutting allowing the cutting of the heel edge by slice consisting of a cutting tool, an element of relative displacement of all the slices allowing to present them one by one to the cutting tool, a slice and system recovery element carrier for subsequent storage item.
- Slice by slice can be cut either by moving the block, the cutting tool being fixed, either by advancing the tool, the block then being fixed. he however, it can happen that both movements are required.
- Figure 1 schematically illustrates the principle of application of the present invention.
- the edge 2 falls on the conveyor belt 9 which will deposit it in a ramp 10 on a cushion of water.
- the storage element 11 will receive the slice in one of its boxes empty 12 and then moves along column 13 thanks to the motor 14 in a substantially perpendicular direction on the plane of the ramp 10.
- the single use plate 4 advantageously consists of a material whose physical and / or chemical properties are close to those of block 1. This plate 4 is also partially sawn by wires or blades during training slices. Separation of slices 2 from heel 3 by the cutting tool 7 is therefore carried out at the single use plate 4 in a perpendicular direction slices 2.
- Figure 2 illustrates more particularly a solution cutting by a band saw 15 driven by wheels 16.
- the cut edge 2 is separated here by a jet liquid from nozzle 17.
- Figure 3 shows more particularly block 1 with its edges 2 partially supported by their heel 3 sawn in the single use plate 4 fixed on the cutting support 5.
- the cutting tool 7 could for example be constituted by a mechanical cutting tool, such than a milling cutter, disc saw, wire saw, band saw or ribbon, or any other cutting system, for example thermal such as laser, plasma, torch, etc., or even a liquid pressure attack or dissolving system chemical.
- the device according to the invention is advantageously used in the case of block of axial symmetry as by example of single crystals of silicon or semiconductor materials of great production. Any block of cut material by wire saws or multi-blades can however be processed by the device which is the subject of the present invention.
- the embodiments described above are in no way limiting and that they can receive any desirable changes to inside the frame as defined by claim 1.
- the cutting tool 7 could be arranged to move perpendicular to slices 2 compared to block 1 which would be stationary.
- Nozzle 17 could be replaced by an installation comprising several nozzles intended to inject a fluid under pressure to facilitate detachment of the last tranche released.
- the device could have a tank containing a liquid, for example water, in which all or part of the device is submerged to prevent drying of slices 2 during the procedure.
- the band conveyor 9 could be replaced by any other means of transport.
- Ramp 10 could be devoid of water cushion or even be removed.
