Vacuum chuck 31 and vacuum spin chuck 32 are safeguarded, when hose aging, directly with a ring hose both can, it is at low cost.This implementation
Example is rotated using the driving methods such as motor, motor driving rotating disc 20, and rotating disc 20 drives vacuum chuck 31 to rotate, thus
Link vacuum spin chuck 32,31/ vacuum spin chuck 32 of vacuum chuck is avoided during rotation, because of 32/ vacuum chuck 31 of vacuum spin chuck
Motionless or asynchronous rotation and cause hose to knot, and damage or influence vacuum chuck 31 to the fixed effect of the absorption of glass pieces 1
Fruit.Certainly, the present embodiment can also be by the driving rotation of vacuum spin chuck 32 to drive vacuum chuck 31 to rotate, to drive rotation
Disk 20 rotate and realize circular grinding polish, herein not the driving method to the adsorbing mechanism of the present embodiment 30 and driving type into
Row limits.
It please refers to shown in Fig. 3, Fig. 4, Fig. 6 and Fig. 7, the polishing mechanism 40 of the present embodiment includes hairbrush 41 and is in horizontally disposed
The axis of rolling 42, hairbrush 41 is sheathed on the axis of rolling 42 and close to vacuum chuck 31, and hairbrush 41 is that axle center rolls with the axis of rolling 42, hair
Brush 41 is in rotary rolling, the glass pieces 1 of the corresponding vacuum chuck 31 of 41 grinding and polishing of hairbrush, since hairbrush 41 is rolled in rotation
During dynamic, the power stirred faced upward or downward can be generated, it is appropriate to reduce the distance between hairbrush 41 and vacuum chuck 31, make
Hairbrush 41 closes on glass pieces 1, hairbrush 41 face upward or downward stir when, hairbrush 41 both can grinding and polishing glass pieces 1
Surface and cambered surface.Preferably, the axis of rolling 42 is arranged along the radial direction of rotating disc 20, so that being sheathed on the axis of rolling 42
Hairbrush 41 can be polished directly glass pieces 1 along the rotation direction of rotating disc 20, since glass pieces 1 are doing circumference fortune
When dynamic, the angular speed of the every bit of glass pieces 1 can be had differences, and different grinding and polishing angles is easy so that under Circulated polishing
Glass pieces 1 every bit the grinding and polishing time it is different, the radial direction by the axis of rolling 42 along rotating disc 20 is arranged so that
The grinding and polishing time of the every bit of glass pieces 1 under Circulated polishing can be identical, has been effectively ensured polishing effect, and
In actual production process, glass pieces 1 are polished directly and can be reduced to greatest extent along the direction that rotating disc 20 rotates
Glass pieces 1 are scraped caused by grinding and polishing process is uneven because of grinding and polishing injures polishing unevenly.When glass pieces 1 are
When the glass cover-plate of 3D model, the cambered surfaces of glass pieces 1 it is as shown in Figure 7 towards hairbrush 41, since rotating disc 20 is opposite hair
41 rotation of brush, so hairbrush 41 can be with respect to glass pieces 1 along direction rotary rolling shown in arrow, hairbrush 41 is in rolling process
In completely at the shallow edge of grinding and polishing glass pieces 1 and cambered surface, to realize to the complete of the glass cover-plate of 3D model
Orientation grinding and polishing.Glass cover-plate grinding and polishing process and 3D model of the burnishing device 100 of the present embodiment to 2.5D model
Glass cover-plate process is similar, and details are not described herein.
Further, polishing mechanism 40 further includes fixed frame 43, and fixed frame 43 connects rack 10, and the pivot joint of the axis of rolling 42 is fixed
Frame 43.Preferably, fixed frame 43 is also connected with girder 50, further to promote the stability of fixed frame 43.Fixed frame 43 is to roll
Axis 42 provides independent rolling support, since rotating disc 20 inevitably generates mechanical shaking during rotation, and it is mechanical
Shake meeting is in horizontal position so that the axis of rolling 42 is not permanent, is avoided by way of adding fixed frame 43 and directly sets the axis of rolling 42
It is placed in rack 10, effectively prevents influence of the mechanical shaking to polishing mechanism 40, effectively promote the burnishing device of the present embodiment
100 grinding polishing effect.
Incorporated by reference to shown in Fig. 3-Fig. 7, the burnishing device 100 of the utility model includes adsorbing mechanism 30 and polishing mechanism 40,
Adsorbing mechanism 30 follows rotating disc 20 to rotate synchronously, and glass pieces 1 are adsorbed on adsorbing mechanism 30 in horizontal, to realize glass
Workpiece 1 follows rotating disc 20 to rotate synchronously, and structure is simple；Polishing mechanism 40 is set to the top of rotating disc 20, due to glazier
Part 1 is adsorbed on adsorbing mechanism 30 in horizontal, and when glass pieces 1 follow rotating disc 20 to rotate synchronously, polishing mechanism 40 can
Surface and cambered surface in horizontal grinding and polishing glass pieces 1, to realize the polishing to 1 surface of glass pieces and repair place
Reason；Multiple groups adsorbing mechanism 30 is set gradually on rotating disc 20, multiple groups adsorbing mechanism 30 rotates synchronously when rotating disc 20 rotates, water
When the flat glass pieces 1 for being adsorbed in different adsorbing mechanisms 30 follow rotating disc 20 to rotate synchronously, polishing mechanism 40 is in horizontal
The surface of grinding and polishing current glass workpiece 1 and cambered surface, greatly promote polishing efficiency, and the quantity of polishing mechanism 40 is rationally arranged,
So that glass pieces 1 can further promote polishing effect by different 40 grinding and polishings of polishing mechanism during synchronous rotation
Rate.
It above disclosure is merely preferred embodiments of the utility model, certainly cannot be practical new to limit this with this
The interest field of type, therefore equivalent variations made according to the patent scope of the utility model still belong to the utility model and are covered
Range.
