Description
Technical Field
The invention relates to the technical field of resistance detection, in particular to a camera device for resistance appearance detection.
Background
In the six-side detection device of the chip resistor, a camera needs to capture images on a rotating disc running at high speed, and the imaging quality is greatly dependent on the type of a light source and the lighting mode.
Since the image taking and the detection must be performed in a short time due to the high-speed detection, the shorter the exposure time, the more advantageous the detection, and the shorter the exposure time, the darker the resistance image taken by the camera. If the brightness of the light source is enhanced in order to ensure the brightness of the image, the resistance image shot by the camera is different in brightness and different in brightness, and the resistance image is greatly different from the resistance image, so that misjudgment is easy to occur when the controller detects the resistance image.
Disclosure of Invention
In view of the defects of the background art, the invention provides an imaging device for detecting the appearance of a resistor, and aims to solve the technical problem that a resistor image shot by the imaging device of the conventional chip resistor six-surface detection equipment is greatly different from an actual resistor image, so that the high-speed detection of the appearance of the resistor is influenced.
In order to solve the technical problems, the invention provides the following technical scheme: the utility model provides a camera device for resistance outward appearance detects, includes the light source mounting panel and sets up the camera in light source mounting panel top, has seted up the light trap in the middle of the light source mounting panel, and the light trap runs through the light source mounting panel, and the camera is shot the resistance image through the light trap, and the recess of ring shape is seted up in the light source mounting panel bottom at the light trap periphery, and recess internally mounted has the light source, and the luminous direction of light source and the contained angle of horizontal plane are between 50 and 70.
Further, the light emitting direction of the light source is at an angle of 60 ° to the horizontal plane.
Further, the light transmission hole is cylindrical in shape, and the diameter of the light transmission hole is 15 mm.
Further, the diameter of the outer ring of the groove is 70-120 mm.
Further, a shading cloth is arranged below the light source mounting plate, and the resistor is placed between the shading cloth and the light source mounting plate for detection.
Compared with the prior art, the invention has the beneficial effects that: the light source shines to the resistance surface with certain angle, and the camera is even when shooing the light source, and the resistance image of the shooting of camera is clear like this, and the resistance is put and is detected on shading cloth in addition, can prevent that the background of the image that the camera was shot is too white, is convenient for detect.
Drawings
The invention has the following drawings:
fig. 1 is a schematic structural diagram of an image pickup apparatus in an embodiment;
fig. 2 is a schematic structural diagram of a bowl-shaped light source.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic views illustrating only the basic structure of the present invention in a schematic manner, and thus show only the constitution related to the present invention.
As shown in fig. 1, a camera device for resistance appearance detection, including light source mounting panel 1 and camera 2 of setting in light source mounting panel 1 top, light trap 3 has been seted up in the middle of light source mounting panel 1, light trap 3 runs through light source mounting panel 1, camera 2 shoots the resistance image through light trap 3, annular shape's recess 4 has been seted up at light trap 2 periphery to light source mounting panel 1 bottom, install light source 5 in the recess 4, the contained angle of the luminous direction of light source 5 and horizontal plane is between 50 and 70.
In this embodiment, lamp source 5 adopts LED lamp pearl, is covered with LED lamp pearl in the recess 4, designs recess 4 for the annular shape LED lamp pearl of being convenient for arranges in recess 4, and the luminous direction of light source 5 is 60 with the contained angle of horizontal plane, through this direction of illumination, the illumination zone of light source 5 can cover whole chip resistor 7, and then ensures that the resistance image that camera 2 was shot is clear.
In the embodiment, the diameter of the outer ring of the groove 4 is 70-120 mm, and the LED lamp beads arranged in the groove 4 are medium-sized ring lights. If the diameter of the outer ring of the groove 4 is larger than 120mm, the LED lamp beads arranged in the groove 4 are large-scale ring lights. If the diameter of the outer ring of the groove 4 is larger than or equal to 30mm and smaller than 70mm, the LED lamp bead arranged in the groove 4 is small-sized annular light.
If large-scale ring light is adopted, in order to avoid overhigh brightness of light irradiated to the surface of the resistor 7 by the LED lamp beads, the distance between the large-scale ring light and the resistor 7 needs to be increased during actual assembly, so that the object distance between the camera 2 and the resistor 7 during large-scale ring light is larger than the object distance between the camera 2 and the resistor 7 during medium-scale ring light, and when the object distance is lengthened, the size of a support required by fixing the light source mounting plate 1 is increased, namely more sectional materials and mounting space need to be used.
If use little type ring light, in order to guarantee that the illumination area of LED lamp pearl can cover resistance 7, need reduce the mounted position of small type ring light and camera 2, the altitude mixture control interval of little type ring light becomes littleer like this, is unfavorable for the outward appearance of large-scale resistance to be detected.
In addition, the thickness of the bowl-shaped light source in fig. 2 needs 48mm at least, while the thickness of the medium-sized ring light is 19mm, when the object distance of the camera 2 is fixed, the height adjusting interval of the bowl-shaped light source becomes smaller, and in addition, the closer the bowl-shaped light source is to the resistor 7, the more the bowl-shaped light source is, the darker the image shot by the camera 2 can be, which is not beneficial to detection.
In this embodiment, the light hole 3 is cylindrical, and the diameter of the light hole 3 is 15 mm.
In addition, in order to avoid the resistance image shot by the camera 2 from having too white background, a shading cloth 6 is arranged below the light source mounting plate 1, and a resistor 7 is arranged between the shading cloth 6 and the light source mounting plate 1 for detection.
In light of the foregoing, it is to be understood that various changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
