Fig. 1 diagrammatically illustrates the structure chart according to the present invention for inhaling vacuum spin chuck device.Fig. 2 diagrammatically illustrates basis
The sectional front view of suction vacuum spin chuck device of the invention.Fig. 3 diagrammatically illustrates suction vacuum spin chuck device according to the present invention
Lateral sectional view.As shown in Figure 1 to Figure 3, show suction vacuum spin chuck device according to the present invention include rotation main shaft 10,
Interface 20 and sleeve 30.
Wherein, rotation main shaft 10 can be formed by any appropriate rigid material, to form the rotational structure of rotating-table apparatus.
At least part of main shaft 10 is rotated, such as top is divided into hollow structure.Hollow structure may be, for example, the form of hollow hole 14.Turn
The end of dynamic main shaft 10 can be connected with the platform that workpiece is received in carrying.After being placed on platform to workpiece, rotation main shaft 10
Hollow hole 14 and workpiece can form confined space.In addition, offering annular groove 12 on the outer surface of rotation main shaft 10, and annular
There is the access being connected to hollow hole 14, access can be the form of such as through-hole 16 in slot 12.
Sleeve 30 can be formed by any appropriate rigid material, be mounted on the outside of rotation main shaft 10.Sleeve 30 must with turn
Dynamic main shaft is coupled, therefore the internal diameter of sleeve 30 is greater than the outer diameter of rotation main shaft 10.In addition, sleeve 30 and rotation main shaft 10 it
Between there are certain gap, and sleeve 30 is born against in external fixed plate 80 (as shown in Figure 3), therefore sleeve 30 is solid
Determine component, is not rotated with rotation main shaft 10.There is opening 32, the position of the opening 32 and annular groove 12 on the outer surface of sleeve 30
Position it is corresponding.In addition, the upper and lower sides of sleeve 30 are mounted on bearing 60, with support rotary main shaft 10 and its radially fortune is limited
It is dynamic.Bearing 60 can be such as thrust bearing.
One end of interface 20 is fixed in the opening 32 of sleeve, is connected to by opening 32 with annular groove 12.Interface 20 it is another
One end can be connect with tracheae, for example, the tracheae of vacuum pump.In embodiments, under the action of vacuum pump, rotation main shaft 10
Air-flow in hollow hole 14 can at least partly be siphoned away by interface 20, so that the pressure in confined space is less than external gas
Pressure.Air-flow when the leakproofness between workpiece and rotation main shaft 10 is good, under the action of vacuum pump continues, in hollow hole 14
It can be siphoned away by most, so that the environment in confined space is nearly or approximately in vacuum state.
As shown in Figure 1 to Figure 3, rotation main shaft 10 is connect by shaft coupling 50 with the rotor of driving motor 40.Rotate main shaft
10 can be rotated by the drive of driving motor 40.In addition, sleeve 30 is fixation member, do not rotated with rotation main shaft 10.Due to connecing
Mouth 20 is connected to by opening 32 with annular groove 12, therefore interface 20 will not be rotated with rotation main shaft 10, to avoid interface 20
The other end connection tracheae there is wrapping phenomena.
Made according to the suction vacuum spin chuck device of the application by opening up annular groove 12 on the outer surface of rotation main shaft 10
It obtains in the case where rotating the rotation of main shaft 10, interface 20 is connected to the cooperation of annular groove 12, is rather than directly to rotation main shaft
It 10 and rotates with, so that the tracheae for avoiding interface 20 from connecting rotates with the phenomenon that winding.Further, the disk of walking around
Function can also be achieved the function of inhaling vacuum, and the air-flow rotated in the hollow hole 14 of main shaft 10 is sucked away by the gas circuit that interface accesses
To form vacuum environment.
The function of inhaling vacuum and the winding of anti-tracheae due to realizing simultaneously according to the suction vacuum spin chuck device of the application, can have
It is widely applied.
For example, the camera lens of infrared optical system is mainly made of lens barrel, optical mirror slip and pressing ring at present.Optical mirror slip is packed into
In lens barrel, eyeglass is pressed with pressing ring, being fixed on it in lens barrel cannot shake.The dispensings works such as installation, the IR of the outer pressing ring of lens barrel
Position requires vacuum suction, makes it possible to be adsorbed on optical mirror slip in respective material hole, convenient for the installation or dispensing of pressing ring
The operation of device.Meanwhile the dispensings station such as installation, IR of the outer pressing ring of lens barrel also needs rotating function, and mounted camera lens is rotated
To next station, the test or operation of next step are carried out, to provide pipelining, improves working efficiency.According to the application's
It inhales vacuum spin chuck device and is applicable to such equipment.The eyeglass of infrared optical system can be placed on to the suction vacuum according to the application
The workpiece of turntable is received on platform, and the hollow structure of eyeglass and rotation main shaft 10 forms confined space, external by interface 20
The effect of vacuum air pump, the air-flow in the confined space is at least partly siphoned away, so that the pressure in the confined space is less than
External pressure adsorbs eyeglass nearly or approximately in vacuum state.
For another example can use cemented doublet in a large amount of on-vehicle lens, cemented doublet is for on-vehicle lens inside optical path
Control realization plays the role of vital.Eyeglass gluing is a highly important step in on-vehicle lens assembling, cemented doublet
There are the optical properties that quality problems will directly influence on-vehicle lens.Automatic glued automatic laminator is being carried out to eyeglass
In, work position rotation table needs high speed to circulate, so that eyeglass stands position, cemented doublet pressing position, glue in dispensing position, upper and lower lens set in succession
It closes between eyeglass solidifies the stations such as position and rotates, to complete the gluing of eyeglass.In general, all there is bubble phenomenon in each piece number of eyeglass, it can
Increase in the turntable station of automatic laminator and inhale vacuum rotary function, eyeglass is adsorbed in corresponding material hole, and is conducive to
The discharge of bubble.Such equipment is applicable to according to the suction vacuum spin chuck device of the application.It can will need one of them glued
Eyeglass is placed in the workpiece receiving platform according to the suction vacuum spin chuck of the application, the hollow structure of eyeglass and rotation main shaft 10
Confined space is formed, by the effect of the external vacuum air pump of interface 20, the air-flow in the confined space is at least partly inhaled
It walks, so that the pressure in the confined space is less than external pressure and adsorbs nearly or approximately in vacuum state to eyeglass.
Above description is only the better embodiment of the application and the explanation to institute's application technology principle.Art technology
Personnel should be appreciated that invention scope involved in the application, however it is not limited to skill made of the specific combination of above-mentioned technical characteristic
Art scheme, while should also cover in the case where not departing from the inventive concept, by above-mentioned technical characteristic or its equivalent feature into
Row any combination and the other technical solutions formed.Such as features described above and (but being not limited to) disclosed herein have it is similar
The technical characteristic of function is replaced mutually and the technical solution that is formed.
