Clean Room Models YK120XC, YK150XC
Compared to standard YX120X and YK150X, clean room models differ in the following points.
1.Robot parameter has been changed. (See section 4 in chapter 2.)
The Z-axis speed is lowered to maintain the degree of cleanliness and the bellows durability. (This is preset prior to shipment.)
2.Suction couplers have been added. (See section 6 in chapter 3.)
For the suction amount versus degree of cleanliness, see "1-1 Basic specifications" in chapter 7. For the location of the suction couplers, see "1- 2 External view and dimensions" in chapter 7.
The suction amount for each suction coupler is very important to maintain the degree of cleanliness and the bellows durability, so always comply with the instruction.
3.R-axis machine reference adjustment is different. (See section 3-4-1-2 in chapter 4.)
The structure around the R-axis origin sensor differs from standard specifications, so the method for adjusting the machine reference is different. Since the Z-axis bellows type suction tube is attached to the R-axis, care must be taken when performing return-to-origin so that the suction tube will not entangle around the R-axis.
4.Different grease is used for the Z-axis drive mechanism. (See section 4 in chapter 5.)
LG2 grease (NSK) suitable for clean room is used for the Z-axis ball screw, ball spline and linear bushing shaft.
Use the LG2 clean room grease for periodic maintenance.
5.Specifications and external appearance are somewhat changed. (See sections 1-1 and 1-2 in chapter 7.)
The X- and Y-axis repeated positioning accuracy and Z-axis maximum speed are different from standard specifications.
The external appearance and dimensions are different in that the Z-axis bellows, flexible tube and suction couplers are added.
