Abstract

The utility model discloses a locating device for marking out TFT-LCD (Thin Film Transistor Liquid Crystal Display) glass, comprising a first knife rest, a second knife rest, a locating push plate, a locating block and a conveyor belt; and the first knife rest and the second knife rest are relatively vertically arranged, a glass plate is arranged between the first knife rest and the second knife rest, and two sides of the glass plate are symmetrically provided with the locating push plate and the locating block. The glass plate is suspended above the conveyor belt. On the premise of ensuring accurate location when the glass plate is marked out, the device provided by the utility model can be used for preventing causing scratches caused by hitching the edge of a product and polluting the conveyor belt when the locating push plate and the locating block return to original points; and finally, the loss of the product can be reduced.

Description

A kind of TFT-LCD of being used for glass localized device of ruling

Technical field:

The utility model relates to a kind of locating device, particularly a kind of TFT-LCD glass substrate line locating device that is used for.

Background technology:

The TFT-LCD thickness of glass substrate is all below 0.7mm, and is very easily broken, overall dimensions 1100X1300mm; Tolerance is positive and negative 0.5mm; Overall dimensions require high, and the singularity of production requires each operation to reduce sheet glass physical dimension deviation as far as possible, make the back engineering add the accurate positioning in man-hour; Reduce the incidence of slashings simultaneously, reduce production costs.

The utility model content:

The purpose of the utility model is to overcome the shortcoming of above-mentioned prior art; A kind of TFT-LCD of being used for glass localized device of ruling is provided; Slashings problem when separating decision bit under the prerequisite of the accurate positioning requirements of this device in satisfying TFT-LCD glass substrate scratching process provides a kind of simple in structure, economical and practical; Processing is simple, changes locating device easily.

In order to reach above purpose, the technical scheme that the utility model patent adopts is:

A kind of TFT-LCD of being used for glass localized device of ruling comprises first knife rest, second knife rest, location push pedal, preset pieces and travelling belt; Said first knife rest and the vertical relatively setting of second knife rest are provided with sheet glass between first knife rest and second knife rest.

Said sheet glass zygomorphy is provided with location push pedal and preset pieces.Said sheet glass is suspended in the travelling belt top.

Under the prerequisite of the device of the utility model accurate positioning when guaranteeing the sheet glass line, prevent when location push pedal and preset pieces recurrence initial point, to hang mashed product edge, pollute feed belt and cause scuffing, finally reduce product loss.

Description of drawings:

Fig. 1 is the apparatus structure synoptic diagram of the utility model;

Fig. 2 is the preceding synoptic diagram of the action of the utility model;

Synoptic diagram when Fig. 3 is the device work of the utility model;

Fig. 4 is a synoptic diagram in the device work of the utility model;

Fig. 5 is a synoptic diagram after the action of the utility model.

Wherein: 1 is the location push pedal; 2 is preset pieces; 3 is travelling belt; 4 is sheet glass; 5 is first knife rest; 6 is second knife rest.

Embodiment:

Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:

Referring to Fig. 1,2,3,4 and 5, a kind of TFT-LCD of being used for glass localized device of ruling comprises first knife rest, second knife rest, location push pedal, preset pieces and travelling belt; Said first knife rest and the vertical relatively setting of second knife rest are provided with sheet glass between first knife rest and second knife rest

Below in conjunction with accompanying drawing the structural principle and the principle of work of the utility model are done further explain.

After product was sent to the line belt, this moment, high-pressure air formed air supporting through the hole on the belt, blew afloat product, and sheet glass is suspended on the line belt (not contacting with belt);

At this moment the preset pieces of ruling rotates to line belt top (origin position is outside the line belt) along the W axle, and drops to the working position, location along the Z axle;

Line location push pedal descends along the Z axle; Move by (origin position is outside the line belt) along X axis line travelling belt direction, promote edge, the long limit of sheet glass, another edge, long limit of sheet glass is contacted with the line preset pieces; After locating device was accomplished the location, the pore on the line belt was become air-breathing by air blowing;

This moment, sheet glass was accomplished the location, carried out the line action on length limit;

After the line action was accomplished, the preset pieces of ruling rose along the Z axle with line location push pedal, and rotates, postpones to origin position separately along W, X axle respectively, and the line action of the location of one-period is accomplished;

The device of the utility model is through the improvement to location push pedal of second knife rest and preset pieces profile; When guaranteeing the sheet glass line under the prerequisite of accurate positioning; Prevent when location push pedal and preset pieces recurrence initial point, to hang mashed product edge, pollute feed belt and cause scuffing, finally reduce product loss.

The technical essential of the utility model:

Line location push pedal and line preset pieces shape such as Fig. 3 are as can beappreciated from fig. 3 before the utility model patent working; Since the rectangle that is shaped as in line location push pedal section and line locating wheel cross section, like this, after accomplishing the line action; They want to rise along the Z axle earlier; Step back and origin position is got back in rotation, this shape is prone to hang glass plate edge in uphill process, causes slashings again;

Fig. 4 is the synoptic diagram behind the utility model patent working; Its technical essential just is in uphill process, to be prone to hang glass plate edge soon for fear of line location push pedal and line location; Cause the phenomenon of slashings; The shaped design in line location push pedal section and line locating wheel cross section in echelon, such wedge configuration guarantees that there are certain clearance in location push pedal and preset pieces with glass plate edge in last process, thereby has solved the slashings problem that causes because of link plate.

Above content is to combine concrete preferred implementation to further explain that the present invention did; Can not assert that embodiment of the present invention only limits to this; Those of ordinary skill for technical field under the present invention; Under the prerequisite that does not break away from the present invention's design, can also make some simple deduction or replace, all should be regarded as belonging to the present invention and confirm scope of patent protection by claims of being submitted to.
