Below the present invention is described in detail by the specific embodiment conjunction with figs., when the effect that is easier to understand purpose of the present invention, technology contents, characteristics and reaches, wherein:
Fig. 1 a to Fig. 1 e is for showing the synoptic diagram of existing combined frame.
Fig. 2 is the synoptic diagram of the automatic optical detecting system of demonstration one embodiment of the invention.
Fig. 3 is the synoptic diagram of the relative position of the image capture unit of the automatic optical detecting system that shows another embodiment of the present invention and combined frame.
Embodiment
Please refer to Fig. 2, the automatic optical detecting system of one embodiment of the invention comprises one first image capture unit 21a, a database 22 and a comparing unit 23.The first image capture unit 21a is in order to capture a pick-up image of a combined frame 1.Pick-up image comprises the engaging zones of combined frame 1.Combined frame 1 is to be applied to a flat display apparatus, and it can be made up of L type member, long strip type member, U-shaped member or above combination, as Fig. 1 a to Fig. 1 e.In an embodiment, first image capture unit can be a charge coupled cell (Charge Coupled Device, CCD), CMOS (Complementary Metal Oxide Semiconductor) (Complementary Metal-Oxide-Semiconductor, CMOS) sensor or contact image sensor (Contact Image Sensor, CIS).Database 22 is at least one with reference to image in order to store.Comparing unit 23 and the first image capture unit 21a and database 22 electrically connect.Stored reference image in the pick-up image that the comparing unit 23 comparisons first image capture unit 21a captures and the database 22, and judge whether the engaging zones of combined frame 1 exists defective.
In an embodiment, stored reference image can be the pick-up image of the combined frame with defective in the database 22.Therefore, the pick-up image that captures as the first image capture unit 21a can be judged that combined frame has defective and must reject when identical with reference to image.When pick-up image with reference to image not simultaneously, combined frame namely is judged to be certified products.The person of noting is judged to be the defective that may comprise new kenel in the qualified combined frame, that is its pick-up image is neither identical with reference image in the database 22.At this moment, the pick-up image that will comprise new kenel defective is stored in the reference image that namely can be used as in the database when detecting next time.
In another embodiment, stored reference image can be the pick-up image of qualified combined frame in the database 22.Therefore, the pick-up image that captures as the first image capture unit 21a is when identical with reference to image, and combined frame namely is judged to be certified products.When pick-up image with reference to image not simultaneously, can judge that combined frame has defective and must reject.
Referring again to Fig. 2, in an embodiment, automatic optical detecting system of the present invention comprises a caution unit 24, and itself and comparing unit 23 electrically connect.Suitable processing can be done in order to warn an operator when comparing unit 23 detects the combined frame with defective in caution unit 24.For example, caution unit 24 can be an indication cresset or shows suitable information warning in a display device.
Please refer to Fig. 3, in an embodiment, automatic optical detecting system of the present invention comprises one second image capture unit 21b.The second image capture unit 21b also is in order to capturing the pick-up image of combined frame, for comparing unit 23 with its with compare with reference to image.In an embodiment, the second image capture unit 21b can be a charge coupled cell, CMOS semiconductor sensor or contact image sensor.As shown in Figure 3, the first image capture unit 21a is the top that is arranged at combined frame, that is the pick-up image direction of the first image capture unit 21a is vertical with the plane at combined frame place.The first image capture unit 21a can be in order to capture the image of overlooking of combined frame.The second image capture unit 21b then is arranged at the oblique upper of combined frame, that is the plane at the pick-up image direction of the second image capture unit 21b and combined frame place has an angle.The second image capture unit 21b can be in order to capture the stravismus image of combined frame.The first image capture unit 21a captures overlook image can be in order to judge inclined weld, defective such as the complete or welding bead breakage of weldering, welding bead partially.The stravismus image that the second image capture unit 21b captures can be in order to judge the not coplanar defective of member that constitutes combined frame, and for example member 11a, 11b have difference in height at engaging zones, as shown in Figure 3.
Referring again to Fig. 3, in an embodiment, automatic optical detecting system of the present invention comprises one first light source 25a, and it is arranged at the upper surface side of combined frame.The first light source 25a is in order to the illumination of upper surface that combined frame is provided, so that the first image capture unit 21a and/or the second image capture unit 21b fechtable are to pick-up image comparatively clearly.In an embodiment, the first light source 25a can be an annular light source, and the first image capture unit 21a then captures the image of combined frames by the medium pore 251 of annular light source, so that the upper surface of combined frame does not have the dead angle of illumination and pick-up image.Be noted that, a plurality of first light source 25a be set also can reach the effect identical with annular light source.In addition, in an embodiment, automatic optical detecting system of the present invention also comprises a secondary light source 25b, and it is arranged at the lower face side of combined frame.So, when complete or welding bead is damaged when welding bead, the light that secondary light source 25b sends namely can see through the defective of welding bead, and is captured and be presented on the pick-up image by the first image capture unit 21a, makes comparing unit 25 be easy to judge defectives such as the complete or welding bead breakage of welding bead.Be noted that the first light source 25a and/or secondary light source 25b can comprise multiple luminous colour system.According to the material behavior of combined frame, operator selectable makes combined frame produce suitable reflection, for the image capture unit pick-up image with the light source that is fit to colour system.
Comprehensively above-mentioned, automatic optical detecting system of the present invention can capture the image of combined frame in the mode of robotization, and institute's picked image is compared to confirm the quality that engages of combined frame with one with reference to image.Therefore, automatic optical detecting system of the present invention can significantly shorten the time of detecting and producing combined frame, and saves the human cost of the joint quality that detects combined frame.
Above-described embodiment only is for technological thought of the present invention and characteristics are described, its purpose makes the personage who is familiar with this technology can understand content of the present invention and is implementing according to this, when not limiting claim of the present invention with it, be that every equalization of doing according to disclosed spirit changes or modification, must be encompassed in the claim of the present invention.
