Patent number: 11365062Abstract: There is provided a conveyance system that conveys a workpiece to each of plural processing apparatuses. The conveyance system includes a conveyance passage, an automated workpiece conveying vehicle that travels on the conveyance passage, a stock unit, and a control unit. The conveyance passage is set in a space directly above the processing apparatus across the plural processing apparatus. The stock unit includes a placement base on which a workpiece stocker capable of housing plural workpieces is placed, two temporary putting bases on which the workpiece carried out from the workpiece stocker on the placement base is temporarily put, a temporary putting base movement part that moves the two temporary putting bases in such a manner as to interchange the two temporary putting bases between a first position that faces the placement base and a second position adjacent to the first position.Type: GrantFiled: November 22, 2019Date of Patent: June 21, 2022Assignee: DISCO CORPORATIONInventor: Satoshi Ohkawara

Patent number: 10622237Abstract: A conveying mechanism for conveying a wafer unit having a wafer disposed inside of and supported on an annular frame by a holding tape includes a housing tray housing the wafer unit therein and a transport unit supporting and transporting the housing tray between wafer treating apparatus. The housing tray includes a ceiling plate and a bottom plate that are interconnected by a pair of side walls facing each other across an opening defined in a side through which the wafer unit can be taken into and out of the housing tray. An air flow generator is disposed on the ceiling plate for generating air downflows in the housing tray that are directed from the ceiling plate into the opening. The transport unit conveys wafer units, one by one, between the wafer treating apparatus.Type: GrantFiled: April 18, 2019Date of Patent: April 14, 2020Assignee: DISCO CORPORATIONInventors: Kazunari Tanaka, Satoshi Ohkawara

Patent number: 7644747Abstract: A rectangular substrate dividing apparatus, which can divide a rectangular substrate in a smaller space, accommodate devices, formed as individual pieces by the division, into device cases, and pick up the devices reliably and efficiently from a protective tape affixed to the back of the rectangular substrate, is provided. This apparatus separates a rectangular substrate, to whose back a protective tape is affixed and on which a plurality of devices are partitioned by a lattice of scheduled-separation lines, along the scheduled-separation lines to divide the rectangular substrate into the individual devices, and accommodates the devices in device cases. In a cutting-responsible region, the rectangular substrate is carried out of cassettes, cut by a cutter, and then cleaned by a cleaner. In a tape peeling-responsible region, the devices are picked up with the protective tape being peeled off. In a device accommodation-responsible region, the picked-up individual devices are accommodated into device cases.Type: GrantFiled: November 29, 2005Date of Patent: January 12, 2010Assignee: Disco CorporationInventors: Satoshi Ohkawara, Kuniharu Izumi, Shigeru Ishii, Ryu Komine
