Description
Technical field
The present invention relates to Electrooptical devices detection field, be specifically related to pick-up unit and the method for etched pattern in a kind of soft printing opacity object.
Background technology
For the detection of the upper etched pattern of printing opacity object (as the film etc.), the checkout equipment shown in Fig. 1 is usually adopted to detect.This checkout equipment comprises the back light 01, glass support plate 02 and the image capture device 03 that are arranged at fixed position.Detected material 04 lies against the upper surface of glass supports.The scattered light that back light 01 sends is through glass vertical irradiation detected material.Light is absorbed when arriving the figure place detected on thing, when arriving the blank space beyond figure, penetrates through after detected material, and therefore the figure detected on thing can imaging in image capture device.
When softer detected material is flat on glass support plate, its surrounding or other parts easily there will be warpage, and then affect the image acquisition of pattern on detected material.For avoiding softer detected material to occur warpage in glass support plane, realize the flattening of detected material by fluting on glass support plate.Fig. 2 shows the checkout equipment figure with fluting on glass support plate.As shown in Figure 2, the upper surface of glass support plate 02 has many grooves be interconnected 05.After detected material 04 lies against the upper surface of glass support plate 02, the air between detected material 04 and glass support plate 02 upper surface is taken away by the space in groove 05 by blower fan, and detected material 04 will be inhaled and be posted on glass support plate 02 upper surface, realizes flattening.
The present inventor finds, glass support plate is offered the flattening that groove can realize detected material preferably, but the groove simultaneously on glass support plate brings other problems again.As shown in Figure 3, the angle of the incident ray and normal of vertically injecting glass support plate is a, and because light injects air by glass, refraction angle b is greater than incident angle, and emergent ray changes transmission direction and cannot enter the shooting area of image capture device.And the shooting area of image capture device can be entered without the light at fluting position after glass support plate, therefore formed by being recessed in image capture device, image is black lines compared to the image of other parts of glass support plate, if the picture registration of pattern in image capture device that this black lines and detected material etch, then cannot judge that whether the pattern that detected material etches is qualified.Intersect if the image of pattern in image capture device that this black lines and detected material etch has or partially overlap, then determine that detected material is substandard product, thus cause a large amount of flase drops.
