Description
Technical field
The utility model relates to a kind of line wheel mechanism, particularly a kind of line wheel mechanism that is used for the semiconductor patent equipment.
Background technology
Semiconductor manufacturing equipment owing to will guarantee the retractable cable wheel speed and turn to consistently, makes the rotation of line wheel controlled to seem extremely important in the process with Buddha's warrior attendant line cutting crystal bar.Common Winder directly drives line storage wheel rotation by motor, has some problems like this, as poor sealing, poor stability, running accuracy is lower, the life-span is short etc.
Summary of the invention
Technical problem to be solved in the utility model provides the line wheel mechanism of a kind of easy to use, good airproof performance, positioning accuracy height, long service life.
The utility model adopts following technical scheme:
The right-hand member of a said line storage wheel left end of the utility model and a rotating shaft is fixed, be provided with two bearings between a rotating shaft and a bearing holder (housing, cover), be provided with inside and outside spacer ring between two bearings, the bearing gland of last item bearing outer-ring and bearing holder (housing, cover) left end are fixed, bearing holder (housing, cover) and drive motors are separately fixed at the two ends of base, establish shaft coupling between the left end of rotating shaft and the motor shaft of drive motors and be connected, last item holds that the retaining of inner ring is female to be threaded with rotating shaft.
The said line storage wheel right-hand member of the utility model flange is provided with the line wheel end cap for sealing.
The utility model said bearing holder (housing, cover) right side and its be concavo-convex ring-type labyrinth seal structure between the shaft shoulder side of right rotating shaft.
The said line storage wheel right-hand member of the utility model flange is provided with the elliptical hole that passes for the end of a thread.
The said bearing of the utility model is an angular contact ball bearing.
The beneficial effects of the utility model: line wheel mechanism provided by the utility model is a kind of simple in structure, easy to use and positioning accuracy is high and the matching used special mechanism of semiconductor manufacturing equipment, its line storage wheel right-hand member is taken turns end cap seal by line, left end is made labyrinth sealing, can prevent that dust, moisture and other impurity from entering bearing, improve the life-span of bearing.Two wing nuts that link to each other with standing screw have been installed on the right-hand member flange of line storage wheel, simultaneously two elliptical apertures have been processed in its vertical direction, when initial coiling, the end of a thread passed the elliptical aperture on the flange, after unclamping wing nut, be drawn to below the wing nut, the fixing the end of a thread of fastening nut so just can wind the line easily then.Bearing holder (housing, cover) and motor are installed on the same cast iron base, can be thereon processing mounting holes simultaneously, improve the axiality of device.Whole device is by the high-precision servo motor-driven, the rotating speed of control line wheel and turning to easily, and simultaneously simple and compact for structure, volume is little, has improved the reliability and stability of whole device.
