Specific embodiment
It is described in detail below in conjunction with specific embodiment of the attached drawing to the embodiment of the present invention.It should be understood that this
Locate described specific embodiment and be merely to illustrate and explain the present invention embodiment, is not intended to restrict the invention embodiment.
Fig. 1 is the knot for being applicable in the cutting equipment of the method and device of amendment glass substrate cutting track of the embodiment of the present invention
A kind of example of structure.It mainly include break bar as shown in Figure 1, being the cutting equipment that can be used for the scribing line cutting of TFT-LCD glass substrate
1, knife rest 2, guide rod 3, servo motor 4, portal frame 5, guide rail 6, the cutting equipment are mountable on Cutting platform 7 to cut and place
Glass substrate on Cutting platform 7.Longitudinal direction when AB line shows glass-cutting substrate in figure.Knife rest 2 and servo electricity
Machine 4 is mounted on portal frame 5, and servo motor 4 drives guide rod 3 to move, and can make knife rest 2 along portal frame 5 along vertical with cut direction
Transverse direction (i.e. the direction vertical with AB line) it is mobile.Portal frame 5 can be moved along guide rail 6, so as to move along the longitudinal direction,
So that break bar 1 prolongs straight line AB scribing line cutting on the glass substrate.Wherein, guide rail 6 is mounted on the two sides of Cutting platform 7.
Fig. 2 is the flow chart of the method for amendment glass substrate cutting track according to an embodiment of the invention.Such as Fig. 2 institute
Show, the method for the present invention includes the following steps:
Step S210, cutting track before obtaining expectation cutting track and correcting.It is expected that cutting track is in cut direction
Straight line, as shown in AB line in Fig. 4.But due to cutting equipment aging, Cutting platform vibration or the factors such as equipment is unstable, before amendment
Cutting track will be generally offset from desired cutting track.As described in Fig. 4 left-half, the one kind for showing cutting track before correcting is shown
Example, Fig. 4 broken line L1 indicate cutting track before correcting.
The transverse movement direction and longitudinal movement direction that drive module can be cut are that reference axis establishes coordinate system, it is expected that cutting
Cutting track can be inputted in the way of coordinate input before cutting track and correcting, or be stored in storage equipment with coordinate form.
Cutting track can also be obtained by the motion profile of record cutting drive module (for example, according to particular moment edge before correcting
The move distance of transverse direction and move distance along the longitudinal direction determine the coordinate of the point on particular moment cutting track).Example
Such as, since expectation cutting track is straight line, thus beginning and end (such as A point and the B of setting expectation cutting track can be passed through
Point) coordinate input desired cutting track, or the coordinate of beginning and end can also be stored in storage equipment, for
Control system is read.
For cutting track before correcting, for example, the motion profile of cutting drive module can be recorded in real time and stored it in
It stores in equipment, cutting track before correcting can also be determined according to the multiple motion profiles recorded in special time period.In practice
It may be arranged as optionally enabling or deactivating the debugging functions to cutting track.When the cutting track of discovering device cannot
When meeting straightness requirement, debugging functions can be enabled, so as to true according to the motion profile of the cutting drive module recorded institute
Cutting track and (or storage) expectation cutting track of input come to amendment cutting track before fixed amendment.
Step S220 is cut before determining the amendment according to cutting track before the expectation cutting track and the amendment
Deviate one or more deviation points of the expectation cutting track in track.Deviation point can be deviate part along offset direction
Vertex, as shown in figure 4, can be C1, D1, E1.The quantity of deviation point and position can be according to the deviation journeys of cutting track before correcting
Degree determines.
For example, deviation can therefrom be chosen according to the coordinate of cutting track before correcting in the coordinate system established as described above
Part is along the vertex of offset direction as deviation point.For example, can be using AB line as longitudinal coordinate axle, so as to cut rail before amendment
On mark, from the curve between the point that adjacent two longitudinal coordinate values are 0, the point for choosing the maximum absolute value of lateral coordinates value is made
For deviation point；Alternatively, can also be before amendment on cutting track, from curve of adjacent two longitudinal coordinate values between 0 point
In, equidistant several points are chosen using on the basis of fore-and-aft distance as deviation point.Deviation point can also side to be manually entered
Formula input, such as several points are therefrom chosen as deviation point after preceding cutting track being corrected by determination, and its coordinate is defeated
Enter in control system.
Step S230 corrects practical cutting track according to the bias that the deviation point deviates the expectation cutting track.
The cutting track for deviateing expectation cutting track can be compensated, such as it can reversely be corrected according to bias,
To make cutting track close to desired cutting track.
Fig. 3 is the flow chart of the method for amendment glass substrate cutting track according to another embodiment of the present invention.Such as Fig. 3 institute
Show, the amendment of cutting track can be realized preferably by following steps:
Step S330 deviates the bias of the expectation cutting track according to the deviation point, corrects the transverse movement
The movement velocity of axis and the longitudinal movement axis, to correct practical cutting track.Pass through the lateral fortune of control cutting drive module
The speed of moving axis and longitudinal movement axis can make up for it due to equipment or environmental factor bring inherent variability, so that controllable cut
Cut track.
Longitudinally perpendicular distance that the bias may include the deviation point apart from the expectation cutting track starting point and
The vertical range of the deviation point and the expectation cutting track.As shown in figure 4, showing the desired cutting track of deviation point distance
Longitudinally perpendicular distance M1 and deviation point and AB line vertical distance N1.

It states.
Thus, it is possible to correct the movement velocity of the transverse movement axis and the longitudinal movement axis according to following equation:
Wherein, MiFor since the starting point of the expectation cutting track to terminal i-th of deviation point on direction apart from institute
State the longitudinally perpendicular distance of desired cutting track starting point, NiFor i-th of deviation point hanging down apart from the expectation cutting track
Straight distance, Vi1Speed is moved after the amendment of longitudinal movement axis when to move from (i-1)-th deviation point to i-th of deviation point
Degree, Vi2Movement velocity after the amendment of transverse movement axis when to move from (i-1)-th deviation point to i-th of deviation point, V are to repair
The movement velocity of cutting drive module before just, i is natural number.Negative sign "-" in above formula indicates opposite direction, i.e., deviates with deviation point
The opposite direction in the direction of AB line.
Above-described embodiment be equivalent to by as shown in right half part in Fig. 4 with correct before cutting track symmetrical track, fold
Be added on amendment before cutting track, thus before compensating approach cutting track offset, comply with desired cutting track.As right
Above-described embodiment is suitably deformed, and deviation point can also be determined using AB line as the symmetrical of axis after determining the deviation point
Point is determined the longitudinally perpendicular distance of symmetric points distance A point and the vertical range of distance AB line, and then is repaired using above-mentioned equation
The speed of positive longitudinal movement axis and transverse movement axis, does not have negative sign among the above when correcting the speed of transverse movement axis at this time.
