Description

The automatic Weighing device of TFT-LCD glass substrate
Technical field
The utility model relates to Weighing device, is specially a kind of automatic Weighing device of TFT-LCD glass substrate that is used on the liquid crystal glass base production line.
Background technology
Along with flat panel displays such as liquid crystal, PDP are more and more ripe, LCD replaces CRT monitor gradually, becomes the electronics main product.Because LCD has advantages such as frivolous, power saving, radiationless line, is applied in large quantities in the various electronic products such as notebook computer, digital camera, TV and mobile communication at present.The image effect of LCD directly affects the market share of product, and glass substrate is as one of most important parts of LCD, and its performance affects the product final mass to a great extent; In the production run of liquid crystal glass base, must the strict generation of controlling glass defect.
Because the moulding of liquid-crystalline glasses and after-processing technology process technology require the degree height, complex procedures, difficulty of processing is big, the manufacturer production cost drops into high, so need control product quality in elementary test as much as possible, avoids substandard product to finish too much technological process on production line, information by Quality Feedback is early to production equipment, technological equipment is made in good time adjustment, thereby guarantees product quality to a great extent, reduces and produces waste.In the glass production process of other types, there is not to adopt the method for weighing to come glass is carried out preliminary check, caused the product after the moulding all to change follow-up manufacturing procedure over to like this, to such an extent as to increased a lot of those underproof products of original processing that are processed into, caused very big waste aborning.
China begins to prepare to produce liquid-crystalline glasses at present, need aspect the control of product, accomplish in time, effectively, so the utility model is considered to design according to the actual needs of this production, this inspection technology is to use for reference on the external inspection technology means, adopt advanced moving-member, the novel checkout equipment of developing according to client's manufacturing process flow needs.
Summary of the invention
The purpose of this utility model mainly is the automatic Weighing device of LCD glass in a kind of LCD glass substrate production line is provided, it can be in the process of glass substrate, utilize the method for measuring weight to come the quality of glass is carried out preliminary check, utilize the detection of the utility model equipment, in time, accurately, low cost, test effect highly significant.
Goal of the invention of the present utility model is achieved through the following technical solutions: the automatic Weighing device of TFT-LCD glass substrate described in the utility model comprises, the bed frame of weighing, be provided in the vertical fastening bracket of the glass mechanism on the bed frame and the electronic balance of weighing from top to bottom successively, and the electric control system of the power system of supporting setting and each parts coordinate operation of control.
The vertical fastening bracket of glass described in the utility model mechanism comprises that mechanism is lifted in bracket base, Mobile Slide, clamping crossbeam, mobile scale, the clamp arm of weighing, the chuck of weighing, lifting location; Described bracket base is fixedly installed on the carriage of the electronic balance of weighing, on bracket base, be equipped with the clamping crossbeam of pair of parallel by Mobile Slide, the slide block of Mobile Slide seesaws with clamping crossbeam, and the guide rail of Mobile Slide is fixed on the bracket base; Pairing is provided with the clamp arm of weighing at a pair of clamping crossbeam two ends, supportingly on the paired clamp arm of weighing in carriage mechanism two ends be provided with the paired chuck of weighing, the lifting location is lifted mechanism and fixedly is provided on the bracket base, is equipped with mobile scale on the clamping crossbeam; The electronic balance of weighing is fixed on the bed frame.The described chuck of weighing adopts the silicon rubber chuck that can realize flexible contact, and the lifting location lifts the mechanism top and the glass contact position is provided with the silicon rubber pad.Preferably set Moving caster and adjust lower margin in the bed frame bottom of weighing.Described power system is an air-path control system.Mechanism is lifted in the location of lifting here
Liquid crystal glass base is after moulding in production process, through cutting action, by induction system with glass vertical transport in blocks to weighing station, clip position is at the coboundary of glass; Under off working state, two clamp arms of glass are releasing orientation under the thrust of cylinder, and the operation of weighing like this is in holding fix, and glass substrate can freely pass through; When glass be about to arrive the operation of weighing and enters duty, electric control system passes to the operation of weighing with detection signal and clamps on the operation valve of cylinder, control cylinder is got back to original position, the clamp arm that loses cylinder thrust is under the effect of extension spring, inwardly clamp simultaneously, jacking frame promotes the jacking axle and rises, both sides and lower limb with glass clamps respectively, the glass chuck of top induction system unclamps, this moment, the weight of glass and clamp arm all concentrated on the following electronic balance, according to the indication result of setting value, can grasp the weight information of product, realize measurement requirement to weighing; After measuring end, electrical control is passed to end signal on the operation valve that clamps cylinder, pass to the glass clamp device of induction system simultaneously, the glass chuck of top clamps glass, subsequently, the glass clamp arm of weighing-appliance unclamps, and detects the glass of finishing and delivers to next station by induction system, and the product of acceptance or rejection is realized processing or rejecting at follow-up station.
The beneficial effects of the utility model are: the utility model equipment is the equipment that is used for the elementary test of LCD liquid-crystalline glasses, and is very high to the accuracy requirement of equipment.Key position all adopts high-accuracy parts in design, and glass clamping and the sliding action that unclamps adopt the straight line slide unit to realize, can reach mobile synchronism and stability.Adopt special silicon rubber chuck with the point of glass contact, such clamping means are flexible, have avoided the damage to glass.The utility model has also solved the fixation problem of large-area ultra-thin glass the weighing time, because self is very unstable when weighing for the thin glass of large tracts of land, if bath of glass level state weighing, the amount of deflection of glass makes the distortion of self very big, not only bad fixing, the requirement on production process does not allow yet.Because the cycle that continuity is produced is limited, and the vitreousness that transports is a vertical direction, so the utility model has adopted the scheme of measuring under the glass plumbness, adopted special glass to fix to clamp method, make glass in the process of weighing, not produce vibration, the numerical value of measuring meets the requirement of user's manufacturing process accurately and reliably.The utility model has been realized glass substrate according to productive temp, carries out large batch of checking measurements on operation.The utility model adopts the electronic balance of most advanced big range of weighing on measuring key parts, the weighing Accuracy Error is presented at 0.2 gram, and special data presentation and output function, make production manager can accurately and timely grasp and control the quality situation of glass, efficiently solve the Preliminary detection problem of LCD glass, result of use is fine on rainbow LCD glass production line.
