Operation, and when the difference of cutter tooth parameter and master blade parameter is located at the predetermined threshold value, it indicates not block in the cutter tooth of break bar
There are impurity, central control machine structure to control break bar and execute cutting operation.In this, whether the present invention, which can detect to block in break bar cutter tooth, has
Impurity, be conducive to avoid to generate shell split, the cutting bad phenomenon such as protrusion, promote cutting quality, reduce the probability of product rejection.
Below for carrying out cutting this application scenarios to glass substrate in LCD industries, and in conjunction with attached drawing, to the present invention
The technical solution of each embodiment is clearly and completely described.In the absence of conflict, following embodiments and its technology are special
Sign can be combined with each other.
Fig. 2 is the structural schematic diagram of the break bar detection device of one embodiment of the invention.As shown in Fig. 2, the knife of the present embodiment
Wheel detection device 20 includes central control machine structure 21 and the photographic unit 22 being connect with the central control machine structure 21.In described
Entreat control mechanism 21 can in order to control break bar to glass substrate execute cutting operation central control board, that is, the knife of the present embodiment
Wheel detection device 20 can be multiplexed the central control board that control break bar executes cutting operation.Wherein, the break bar can be Fig. 1 institutes
The break bar 10 shown, structure can be shown refering to fig. 1.
Fig. 3 is the schematic diagram of a scenario that break bar detection device shown in Fig. 2 is installed on cutting equipment.Referring to Fig. 3, break bar is solid
Due in the mounting bracket 31 of cutting equipment 30, the photographic unit 22 is set to 31 side of the mounting bracket, neighbouring with this
Break bar is arranged, and the photographic unit 22 before break bar cuts glass substrate 32 to be cut for shooting working as break bar
Preceding image, such as picture or image.Central control machine structure 21 is used to obtain the cutter tooth parameter of break bar according to the present image of shooting,
And compare the cutter tooth parameter and preset master blade parameter, the preset master blade parameter, which can be considered, to be met
The cutter tooth parameter of split requirement, then central control machine structure 21 determine whether break bar executes cutting operation according to comparing result.
When the cutter tooth parameter is identical as master blade parameter, indicate that break bar currently meets split requirement, it is believed that knife
Not blocking in the cutter tooth of wheel has the impurity such as glass dust, and central control machine structure 21 can control break bar and execute cutting operation.And in institute
When stating cutter tooth parameter and master blade parameter and differing, indicate that break bar does not meet split requirement currently, it is believed that the cutter tooth of break bar
Middle card has the impurity such as glass dust, and central control machine structure 21, which must control break bar, to be stopped executing cutting operation.
Wherein, central control machine structure 21 is to obtain the mathematics measurement parameter of break bar according to obtained image is shot, this
Mode is substantially to be judged and calculated according to the grayscale value of captured image, and the variation of grayscale value is by photographic light sources
Intensity and angle influence.In practical application scene, the intensity and angle of light source are difficult to remain unchanged, that is, according to present image
It obtains cutter tooth parameter and inevitably there is error.In order to eliminate the error to ensure that precise control, the present invention can be based on the break bar
Detection device 20 realizes break bar detection method shown in Fig. 4.
As shown in figure 4, the break bar detection method includes：
S41：One break bar detection device is provided, the central control machine structure and photographic unit of connection are included.
S42：Photographic unit shoots the present image of break bar.
S43：Central control machine structure according to the present image obtain break bar cutter tooth parameter, and by the cutter tooth parameter with
Preset master blade parameter is compared.
S441：When the difference of the cutter tooth parameter and master blade parameter exceeds predetermined threshold value, central control machine structure control
Break bar processed stops cutting operation.
S442：When the difference of the cutter tooth parameter and master blade parameter is located at predetermined threshold value, central control machine structure control
Break bar processed executes cutting operation.
That is, the present embodiment can be with a preset predetermined threshold value, only in the cutter tooth parameter and master blade parameter
Difference when exceeding the predetermined threshold value, could assert that current break bar does not meet split requirement, blocking in the cutter tooth of break bar has glass powder
The impurity such as dirt, central control machine structure 21, which controls break bar, to be stopped executing cutting operation, and is joined in the cutter tooth parameter and master blade
When several differences is located at the predetermined threshold value, assert that current break bar meets split requirement, not blocking in the cutter tooth of break bar has glass dust
Equal impurity, central control machine structure 21 can control break bar and execute cutting operation.
In this, whether the break bar detection device 20 of the present embodiment, which can detect to block in the cutter tooth of break bar, impurity, is cutting
When glass substrate 32, be conducive to avoid glass substrate 32 generate shell split, the cutting bad phenomenon such as protrusion, to promote cutting product
Matter reduces the probability of product rejection.
In the present embodiment, the cutter tooth parameter includes but not limited to radian value, the number of teeth, tooth depth and the tooth for cutter tooth
At least one of angle.By taking the radian value of cutter tooth as an example, when new break bar is installed or before executing each cutting operation, inspection
The cutter tooth radian value X1 of break bar is surveyed and recorded, then shoots the image of break bar, and radian is carried out to the cutter tooth of break bar and is calculated
To obtain cutter tooth radian value Xn, then cutter tooth radian value X1 and cutter tooth radian value Xn are compared.If there is glass dust etc.
Impurity is caught in the unusual condition of cutter tooth, then the radian value of single or multiple cutters tooth can change, at this time Xn ≠ X1, you can assert
Break bar does not meet split requirement currently.
Please continue to refer to Fig. 2 and Fig. 3, the break bar detection device 20 can also include being connect with central control machine structure 21
Blowing mechanism 23.When assert that break bar does not meet split requirement, i.e. Xn ≠ X1 currently, central control machine structure 21 controls blowing mechanism
The cutter tooth of 23 pairs of break bars purges, and the impurity being caught in cutter tooth is removed with this.Then, above-mentioned steps S42 is continued to execute
And S43, until when the difference of the cutter tooth parameter and master blade parameter is located at predetermined threshold value, i.e. Xn=X1, central control machine
Structure 21 can just control break bar and execute cutting operation to glass substrate 32.
It should be understood that above-mentioned break bar detection device 20 is only to illustrate the goal of the invention schematic diagram of the present invention, on this basis, root
According to the demand of practical application scene, the present invention can design the shape of each structural detail of the break bar detection device 20, and select
Select suitable device.For example, the blowing mechanism 23 can be air blast (Air Blow).In another example the photographic unit 22 can
Think CCD (Charge Coupled Device, charge coupling device) camera.
Based on this, example, is not intended to limit the scope of the invention the above is only the implementation of the present invention, every profit
Technical characteristic between the equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content, such as each embodiment
Be combined with each other, be applied directly or indirectly in other relevant technical fields, similarly be included in the present invention patent protection
In range.
