Abstract

The automated fluorocarbon spraying apparatus uses fluorocarbon spray under high pressure, i.e., between 800 and 1200 psi, to remove surface particles by the mechanism of momentum transfer. The automated fluorocarbon spraying apparatus finds particular utility for cleaning a device known as an autostacker which is used for transporting magnetic disks to, from and within the process during their manufacture. The process for manufacturing magnetic disks is subject to contamination problems and is performed in class 100 work areas. By automating the autostacker cleaning process, the cleaning time is reduced and there is little or no residual contamination. A plan view of the automated fluorocarbon spraying apparatus is shown in Fig.

Automated Fluorocarbon Spraying Apparatus

The automated fluorocarbon spraying apparatus uses fluorocarbon spray under high pressure, i.e., between 800 and 1200 psi, to remove surface particles by the mechanism of momentum transfer. The automated fluorocarbon spraying apparatus finds particular utility for cleaning a device known as an autostacker which is used for transporting magnetic disks to, from and within the process during their manufacture. The process for manufacturing magnetic disks is subject to contamination problems and is performed in class 100 work areas. By automating the autostacker cleaning process, the cleaning time is reduced and there is little or no residual contamination. A plan view of the automated fluorocarbon spraying apparatus is shown in Fig. 1, and it includes two stations where a first station 50 has a pair of doors 55 through which the autostacker enters and thereafter functions to enclose the station where the spray cleaning process occurs. A second station 100 functions as an interlock from the first station to the clean work area. An autostacker (not shown) is automatically conveyed to the first station 50 where a centrally located nozzle 60 having a circular configuration is located for cleaning the outer cylindrical cover of the autostacker. Two semi-circular nozzles 65 are movable in a vertical plane and function to spray the autostacker as they move. Cooling coils 70 (Fig. 2) facilitate distillation and recovery of the fluor...
