Description

Optical detection device

The present invention relates to an optical detecting device, and more particularly to an optical detecting device capable of obtaining an accurate image in response to a small size of an object to be tested.

The optical detecting device is a non-contact surface detecting device applied to the production line, which adopts an optical principle to extract the surface image of the finished product, so that the inspector can confirm the defects and flaws on the surface of the finished product, thereby achieving the production line. Quality management and monitoring.

The prior art of the related optical detecting device, as disclosed in US Pat. No. 8,570,504 B2, the finished product carried on the conveyor belt, the image of each side of the finished product is projected to the beam splitter through a mirror group, and the image is transmitted through the beam splitter. Passing to a telecentric lens and a camera device, the surface states of the four sides of the object to be tested, such as a screw, are collected on a screen, as shown in FIG. 9, and the tester confirms the surface of the finished product. Defects; the camera device, such as a CCD camera, has a field of view (FOV) of 6.4 mm * 4.8 mm under the condition of using a 1/2 CCD.

However, when the size of the object to be tested changes, such as the need to detect a smaller screw, the prior art cannot maintain the original detection accuracy in the same manner; when the inspection personnel do not adjust the optical detection device, The image of the four side images of the object to be tested is taken as shown in FIG. 10, and the obtained image is also reduced with the object to be tested, so that the image cannot be clearly interpreted; if the inspector only adjusts the magnification of the telecentric lens, The image obtained is as shown in Fig. 11. Under the same field of view, although the image of the four sides of the screw can be slightly enlarged, it is still not enough to judge the surface state of the finished product; only the inspector needs to adjust the telecentric lens at the same time. The magnification and the angle and position of the mirror group can obtain an image of the finished product to be detected that is clear enough to discriminate the surface defect, as shown in FIG. 12, at this time, due to the relationship of the magnification adjustment of the telecentric lens, the imaging device will be made.

The operation.

The finishing mirror 41 of the finishing lens set 40, the raising frame of each mirror group of the receiving mirror group 50, and the first cone mounting seat 31 of the cone group 30 are such that the finishing mirror 44 and each The mirror and the first cone mirror 32 are at the same height as the conveyor belt 23 to facilitate image reflection on the surface of each side of the object to be tested 70.

When the inspector wants to perform the interpretation of the outer contour of the finished product, please refer to FIG. 2 and FIG. 5. The fourth embodiment of the present invention is further based on the first, second or third embodiment. The backlight is generated from the mounting side 622 of the fixing base 62 of the beam splitter group 60. At this time, the illumination group above the object to be tested 70 can be closed. When the backlight 90 is illuminated, the light will pass through the beam splitter 63. Reversely traveling along the first reflective path 81, the second reflective path 82, the third reflective path 83, and the fourth reflective path 84; backlight rays traveling along the first reflective path 81 are sequentially arranged The mirror 44 and the first mirror 510 are reflected, pass through the object 70 to be tested, and then travel along the third reflection path 83, and sequentially reflect to the third mirror 530 and the first cone mirror 32. Then, the spectroscope 63 is reflected to the telecentric lens group and the imaging device is imaged to form a background light of the third side edge 73 of the object to be tested 70. At this time, the surface state of the object to be tested 70 is dark, and the background phase It is relatively bright, so the outline of the object to be tested 70 is quite clear and sufficient for inspection. The measuring personnel determines whether the shape of the object to be tested 70 is damaged, as shown in FIG. 8; oppositely, the backlight light traveling along the third reflecting path 83 sequentially follows the first cone mirror 32 and the third mirror. The reflection at 530 passes through the object 70 to be tested, and then travels along the first reflection path 81, sequentially reflects to the first mirror 510 and the alignment mirror 44, and is reflected by the beam splitter 63 to the telecentric mirror. Forming and imaging the imaging device to form a background light of the first side edge 71 of the object to be tested 70; forming a background light of the second side edge 72 and the fourth side edge 74 of the object to be tested 70 is the same as the first The backlight of the one side edge 71 and the third side edge 73 will not be described herein.

The backlight source and the light source of the illumination group are not limited thereto, and the backlight source and the illumination group can simultaneously apply a light source to the object to be tested 70, so that the tester can simultaneously interpret the object to be tested 70. a surface state and a contour; in the fourth embodiment of the present invention, the first mirror 510, the second mirror 520, the third mirror 530, and the fourth mirror 540 are away from the end of the conveyor belt 23 The angle α of the moving direction of the conveyor belt 23 is 67.5 degrees.

The above description is only a preferred embodiment of the present invention, and does not impose any form limitation on the present invention. Although the present invention has been disclosed above in the preferred embodiment, it is not intended to limit the present creation, and has any technical field. A person skilled in the art can make some modifications or modifications to equivalent embodiments by using the above-disclosed technical contents without departing from the technical scope of the present invention.
