Description
Technical field
The invention belongs to a kind of display floater manufacturing equipment, especially a kind of display panel thin grinder.
Background technology
Display floaters such as LCD Panel more and more are applied in the portable electronic equipment (as notebook computer, PDA etc.), and one of emphasis that weight is portable product to be paid close attention to, alleviating of each gram weight all is of great value.With approaching that the glass of LCDs is done as far as possible, be one of approach that reduces weight.Nowadays some finished fluid crystal display screen thickness of glass is reduced to 0.2 millimeter from general 0.9 millimeter.Reach such thickness of glass, need realize by grinding step.
At present, normally used display floater is carried out the milling apparatus of thinning can be with reference to shown in Figure 1, it includes overhead gravitation tank, lapping liquid holding vessel, grinding plate, the described lapping liquid holding vessel of connection and the lapping liquid pipeline of described overhead gravitation tank, many conduits that are connected described overhead gravitation tank and grinding plate etc.During use, (liquefied mixture of abrasive and water, abrasive itself is a solid state powder to lapping liquid, adopts as CeO usually
2) squeeze into overhead gravitation tank (head tank) by pump from lapping liquid holding vessel (slurry supply tank), the lapping liquid supply line is connected with overhead gravitation tank tank skin marginal position, after lapping liquid supplies to overhead gravitation tank inside, supply to grinding plate along the revolution of overhead gravitation tank inwall and through conduit again.
The shortcoming that the milling apparatus of this structure exists is: the flow distribution that lapping liquid is supplied with is inhomogeneous, thereby cause glass substrate zones of different grinding efficiency (polishing rate) inconsistent, activity duration (tack time) is promoted, increase and make production cost.
In addition, equipment in use needs water and feeds, and the effect of water mainly contains two: 1. in process of lapping, when needed, water can dilute lapping liquid; 2. owing to abrasive (as CeO2) easily the precipitation caking be attached in the board or on the polishing pad (Polish pad), at this moment need water to clean.In the prior art, some milling apparatus is connected a water pipe with the middle position stream of overhead gravitation tank, and its water pipe passes through solenoid control.
But, present this water pipe inserts and also has some shortcomings in structure: (1) is after magnetic valve stops to supply water, the residual one section water of meeting in the water pipe between magnetic valve and the overhead gravitation tank (head tank), the uncontrolled outflow of water meeting in the water pipe, when carrying out the polishing pad pressing, it is not firm that these water might cause polishing pad to attach, and in the reduction polishing pad life-span, increases cost.(polishing pad polish pad, significant feature is that cell glass is carried out rubbing, the effect of somewhat similar sand paper.Polishing pad itself has one deck gum, directly is attached on the board and coils, and the main material of polishing pad is a bipeltate.Glass substrate is to be adsorbed on the lower wall by vacuum suction pad (VAC pad), does not move when grinding.); (2) when carrying out the board cleaning, lapping liquid residual in the lapping liquid pipeline can't clean totally by water, if long-time the shutdown, lapping liquid can lump and be not easy to find, clean in pipeline; If can't cleaning totally, caking, foreign matter can cause pipeline blockage, and, in case lump can cause fragmentation among flowing into grinding system.
Summary of the invention
The objective of the invention is: a kind of display panel thin grinder is provided, can makes the flow distribution of lapping liquid feed system even, make glass substrate zones of different grinding efficiency unanimity; Simultaneously can clean lapping liquid residual in the lapping liquid pipeline better, avoid it to influence polishing pad and attach, reduce cost, the convenient cleaning saved the maintenance time, improves yield.
Technical scheme of the present invention is: a kind of display panel thin grinder, it comprises overhead gravitation tank, lapping liquid holding vessel, grinding plate, the described lapping liquid holding vessel of connection and the lapping liquid pipeline of described overhead gravitation tank, many conduits that are connected described overhead gravitation tank and described grinding plate, the connector of described conduit and described overhead gravitation tank is distributed in the bottom of described overhead gravitation tank, and described lapping liquid pipeline is inserted by overhead gravitation tank center of top position.
Below technique scheme is further explained:
Described display panel thin grinder also includes the water pipe of a transporting water, and water pipe is linked on the lapping liquid pipeline.
Described display panel thin grinder also includes one and carries compressed-air actuated compressed air tracheae, and the compressed air tracheae is linked on the lapping liquid pipeline.By adding the compressed air tracheae, can clean the lapping liquid pipeline better.
The lapping liquid tube control flap that described lapping liquid pipeline is provided with the input of control lapping liquid or closes.
The conduit control valve door that described water pipe is provided with the input of control water or closes.
The compressed air tracheae by-pass valve control that described compressed air tracheae is provided with the input of control compressed air or closes.
The lapping liquid tube control flap that is provided with the input of control lapping liquid or closes near lapping liquid holding vessel one end on the described lapping liquid pipeline.
Described water pipe inserts the on-position of lapping liquid pipeline between lapping liquid tube control flap and overhead gravitation tank, and as close as possible lapping liquid tube control flap.Factor that whole lapping liquid pipeline effectively cleaned has been considered in this on-position.
Described compressed air tracheae inserts the on-position of lapping liquid pipeline between lapping liquid tube control flap and overhead gravitation tank, and as close as possible lapping liquid tube control flap.Factor that whole lapping liquid pipeline effectively cleaned has been considered in this on-position.
Advantage of the present invention is:
1. display panel thin grinder of the present invention can make the flow distribution of lapping liquid feed system even, makes glass substrate zones of different grinding efficiency unanimity.Simultaneously, water pipe is linked on the lapping liquid pipeline and can cleans lapping liquid residual in the lapping liquid pipeline better.Because of the water pipe access point is lower than the overhead gravitation tank, avoid the uncontrolled inflow overhead of residual water gravitation tank in the water pipe, attach and influence polishing pad, can effectively reduce production costs, the convenient cleaning saved the maintenance time, improves yield.
2. display panel thin grinder of the present invention adds the compressed air tracheae, can clean the lapping liquid pipeline better.
3. display panel thin grinder of the present invention can be by realizing existing equipment transformation, and transform conveniently, is beneficial to popularization.
