Definitions

  • the invention relates to a method and an apparatus for inexpensive, low contamination, packaging of broken polysilicon.
  • Polysilicon fracture is used, for example, using the Siemens process deposited from trichlorosilane and then free of contamination crushed. It is usually used in the solar or semiconductor industry for example for the production of solar cells or high-purity silicon wafers. For these applications is as little contaminated polysilicon breakage as possible desired, so the material is for transportation too packaged for users. However, this packaging is done Previously rich in contamination and labor intensive manual.
  • the object of the invention is to provide a method provide an inexpensive low-contamination packaging of high-purity polysilicon fragments.
  • the problem is solved by a method which thereby is marked that the polysilicon break automatically is packed.
  • an automatic packaging machine is used Device used according to claim 1.
  • the inventive To reduce the risk of contamination of the polysilicon break avoid all are in contact with the polysilicon fracture Parts of the device according to the invention reinforced with silicon or with a highly wear-resistant Plastic clad. It is also particularly preferred to minimize puncture of the packaging, the inventive To design the device so that the polysilicon break packed by two sealed plastic bags is.
  • a packaging machine particularly preferably comprises therefore after the welding device for the with polysilicon break filled plastic bag another filling device, comprising a plastic bag and one Welding device for this plastic bag, the one contains plastic bag filled with broken polysilicon.
  • a device according to the invention preferably also enables the polysilicon break is also transported fully automatically and therefore also includes means to promote polysilicon breakage such as a conveyor trough, a conveyor pipe, a conveyor belt, or a brush belt.
  • Means for portioning the polysilicon fraction are, for example a time-controlled conveyor trough or a level determination of a storage container or a weighing device for the polysilicon break.
  • the filling device preferably forms the plastic bag from a preferably high-purity plastic film, for example by means of a filling and bag tube.
  • the Device also one above the filling device for the Polysilicon and the welding device attached air suction device (Flowbox), which is a particle contamination of the Polysilicon breakage prevented.
  • Flowbox air suction device
  • Figure 1 represents a particularly preferred embodiment of the Invention represents:
  • the device according to the invention preferably subsequently comprises a further filling device on the conveyor belt (12) (15), which from a high-purity plastic film (16) Plastic bag (17) forms a welding device (18) for this plastic bag (17) after being welded to the and plastic bags filled with broken polysilicon (14) is filled, and a conveyor belt (19) for in one Double bag packaging (21) located polysilicon break (2).
  • the filling device (6) preferably comprises a deionizer (9), which is a static charge and thus a particle contamination the plastic film (7) prevented.
  • the conveyor belt (12) and / or the conveyor belt preferably runs (19) by a magnetic inductive detector (13) or (20).
  • the plastic film (7, 16) is preferably around a PE film.
  • the plastic film preferably has one Thickness of> 200 ⁇ m, particularly preferably a thickness of 290 up to 350 ⁇ m.
  • the device according to the invention enables low-contamination Packaging without human contact. It also enables a consistent quality of the packaged product.
  • the polysilicon break (2) is on a silicon armored Conveyor trough (1) transported in a weighing device (3), wherein the weighing device with the filling level of a funnel (4) Polysilicon break (2) regulates itself and the polysilicon break (2) emptied from the funnel (4) into a plastic bag (8), if there is a predetermined filling quantity of broken polysilicon (2) located in the funnel (4), the drop height of the silicon is minimized with baffles (5), so that an undesired Post-comminution of the silicon does not take place and the plastic bag (8) after filling by means of a Welding device (10) welded and the so obtained plastic bag (14) filled with broken polysilicon via a Conveyor belt (12) through a magnetic inductive detector (13) is carried out in order to detect possible metal contamination.
  • the plastic film (7) is preferred in the filling device (6) formed into a plastic bag (8) in that the film (7) is pulled over a shoulder.
  • the shoulder is, in order not to contaminate the film surface, again made of highly wear-resistant plastic.
  • the neighboring ones Ends of the plastic film formed into a tube are welded, the hose is covered by a Welding device welded shut so that a fillable from above high purity plastic bag is present, which is preferred during the filling with the polysilicon break through further continuous welding of those forming a tube Plastic film is extended.
  • the single bag is particularly preferred in another Packed in a plastic bag. This is done by a second plastic bag analogous to the first plastic bag is generated and the single bag is introduced into the second bag and is welded. Preferably one brakes mechanical-pneumatic product brake the case of the first Plastic bag when inserted in the second plastic bag.
  • the polysilicon fragments packaged in this way can be transported again via conveyor belts guided by a magnetic inductive detector in order to detect possible metal contamination.
