Main improvement – X-Y
The assembly precision is
improved by obtaining
concentricity of X-motor and
b/screw.
Improved assembling ability by pin
assembly of X-Y assy. (Assembly
clearance by processing is obtained)
To prevent modification after assembling
in module unit, the structure is improved to
simply assemble Y-b/screw after
assembling X-Y body.
Improvement of grease application
method to Y driving part
(The difficulty of approach is solved
when applying grease to 2-gantry)

z Structure
• ENTRY SHUTTLE ASSY : Composed of front and rear moving rail. Performs width trimming and shuttle
movement with one ball screw and two motors.
• WORK ZONE ASSY : Composed of front and rear placement zone. Performs width trimming with lead
screw and motor and performs PCB settling function in relation with BUT.
• EXIT SHUTTLE ASSY : Composed of front and rear moving rail. Performs width trimming and shuttle
movement with one ball screw and two motors.
• Composed of dump box and cable wiring related parts.
