Abstract
The related crossing laser locator for liquid crystal substrate detection comprises: a base platform with a rectangular placing area for sample, two rotary swing assemblies on near corners by everyone with a connection block contained a laser source to be driven rotating given angle and up-down swing. Wherein, the laser rays cross in the placing area, as persistence of vision, it determines the crossed position as the target.
Description
Technical field
The present invention is relevant with the technology that positions mark for the specified point on the sheet material, is meant the cross type laser positioning apparatus that a kind of crystal liquid substrate detects especially.
Background technology
Press, in the mode of known detection crystal liquid substrate, normally shine on crystal liquid substrate to be detected, again with the reflection or the perspective state of operator's visual inspection light with a specific light source, find out the flaw point on the crystal liquid substrate, after finding out, traditional approach is to photograph with CCD (charge-coupled device (CCD)), and is shown on the screen, the operator need operate the CCD displacement, make the gauge point on the screen be aligned with the flaw point, and make pick-up unit remember the coordinate of this flaw point, and then for subsequent treatment.Only, in operation, may influence the precision of CCD displacement, also might shelter and a little cause temporal waste because of the user looks for the flaw on screen because of personnel's proficiency.
The applicant is in propose a kind of technology that the flaw point of crystal liquid substrate is indicated with laser light a few days ago, and got permission patent, it announces " the laser marker mechanism that crystal liquid substrate detects " utility model patent the 555th, No. 018 for Taiwan, has solved the disappearance of aforementioned known mark mode.
The applicant is in the process of using, find in the technology of above-mentioned laser labelling, because being two slide blocks, its structure cooperate the driving of two drivers to come slippage on two slideways, therefore its structure is comparatively complicated, and the time that displacement spent is longer, cause the specifically labelled time longer, and still have the space of improvement.
Summary of the invention
Fundamental purpose of the present invention is to provide a kind of cross type laser positioning apparatus of crystal liquid substrate detection, and its specifically labelled time is shorter, can orient the flaw point faster.
An of the present invention purpose is to provide a kind of cross type laser positioning apparatus of crystal liquid substrate detection, and it is simple that its structure is used always, and cost is lower.
For achieving the above object, the cross type laser positioning apparatus that a kind of crystal liquid substrate provided by the present invention detects includes:
One base station has a rectangular storing zone on it, can be for putting crystal liquid substrate to be detected;
Assembly is waved in two rotations, lay respectively at this and put extra-regional adjacent two corners, respectively this rotation is waved assembly and is had a contiguous block, can be driven and rotate predetermined angular and teeter, respectively has a LASER Light Source on this contiguous block, by the rotation respectively this contiguous block in a predetermined angular, the light that this dual-laser light source is sent intersects, and crossover location is positioned at this storing zone, again, shine back and forth in this storing zone by waving the light that this contiguous block respectively sends this dual-laser light source, utilize the persistence of vision effect of naked eyes and go up formation cognizable two straight lines that intersect in this storings zone, the position of intersection can be as the position location.
Wherein: respectively this rotation waves that assembly mainly waves driver by a rotating driver, a universal stage, one and a contiguous block is formed, this rotating driver is located at this base station, this universal stage is connected in this rotating driver, be subjected to the driving of this rotating driver and rotate predetermined angular, this waves driver and is positioned on this universal stage, this contiguous block is connected in this and waves driver, is subjected to this to wave the driving of driver and teeters.
Wherein: this waves driver and cooperates a cam to be formed by a motor, this motor is located on this universal stage, this contiguous block is articulated on this universal stage, and has an elongated hole and act on this cam, acts on this slotted hole during by this cam rotation and this contiguous block is waved.

Embodiment
As shown in Figures 1 to 4, the cross type laser positioning apparatus 10 that a kind of crystal liquid substrate that a preferred embodiment of the present invention provided detects mainly waves assembly 21 by a base station 11 and two rotations and is formed, wherein:
This base station 11 has a rectangular storing zone 12 on it, can be for putting crystal liquid substrate (not shown) to be detected;
As shown in Figure 1, when detecting crystal liquid substrate, earlier a crystal liquid substrate (not shown) to be detected is placed in the storing zone 12 on this base station 11, detect again, when finding out flaw point, can drive this two rotation and wave contiguous block 28 rotations of assembly 21, make the laser light of this dual-laser light source 29 intersect at the position of this flaw point, and teeter (its swinging condition as shown in Figure 5) by driving this two contiguous block 28, the light that this dual-laser light source 29 is sent shines back and forth in this crystal liquid substrate (not shown), utilize the persistence of vision effect of naked eyes and on this storing zone 12, form cognizable two straight lines that intersect, its crossing condition as shown in Figure 6, Figure 7 shows that the state that another flaw point is upward intersected by laser light, the operator can judge place, flaw point position on the crystal liquid substrate by each crossover location, thus, can reach the effect of mark location.
As from the foregoing, characteristics of the present invention are:
One, the location fast: the present invention waves assembly 21 by this two rotation of driving LASER Light Source 29 is intersected, and it only has spinning movement, can arrive the precalculated position at short notice, and compared to common technology, locating speed of the present invention is faster.
Two, simple in structure, with low cost: assembly 21 is waved in two rotations of the present invention, only is arranged at two corners outward, storing zone 12 of base station 11, does not need slipping mechanism, and structure is more simple than common technology, and manufacturing cost is more cheap.
