Description of the embodiments
The invention provides an electronic component inspection apparatus. The following detailed description of the present invention is provided in connection with the accompanying drawings, so as to facilitate understanding and grasping thereof.
Electronic component check out test set, electronic component includes electric capacity, resistance, inductance, as shown in fig. 1 and 2, and check out test set includes: the device comprises a loading unit 1, a transmission unit 2, a detection unit 3 and a sorting unit 4.
The loading unit 1 is used for loading electronic components and discharging, and generally consists of a loading cabin, a vibration disc and a discharging guide rail.
The transmission unit 2 comprises a transparent transmission disc 21 for carrying the electronic components 5 and transmitting, a motor for driving the transparent transmission disc 21 to rotate, an encoder for controlling the rotation amount of the transparent transmission disc 21, and a start sensor 22 which is in communication connection with the encoder and is used for monitoring the start position of the electronic components 21.
Specifically, the encoder outputs an electric pulse, that is, controls the angle signal output of the transparent transmission disk 21, and triggers the detection unit 3 to respond. The transparent driving disc 21 is used for bearing the electronic components 5, the electronic components 5 are transported to the periphery of the transparent driving disc 21 from the discharging guide rail of the loading unit 1, and the detection positions are switched by the rotation of the transparent driving disc 21 and finally enter the sorting unit 4.
The detecting unit 3 is used for detecting six sides of the electronic component 5, and comprises at least eight detecting units 6, wherein six detecting units 6 are base detecting units 61, the base detecting units 61 correspond to six sides of the electronic component 5, and the other detecting units 6 are selective reinforcing units 62 with any surface.
Specifically, the conventional inspection unit 3 includes only six fixing positions at most, and can independently inspect six surfaces of the electronic component 5 at one time, so that all defects on one surface cannot be inspected accurately at one time no matter how precisely an image pickup mechanism is adopted.
The scheme adopts the selective reinforcement machine 62 to carry out supplementary accurate detection, can carry out secondary or even tertiary detection on certain surfaces with higher specific requirements, and accurately detects the conditions of breakage, crack, color, copper exposure and size. The detection precision of the equipment is improved, and the detection efficiency is not affected.
And the sorting unit 4 is used for sorting and collecting the electronic components 5 according to the detection condition of the detection unit 3.
The detector position 6 is described in detail, and comprises a camera shooting mechanism 7 and an angle adjusting mechanism 8 for adjusting a camera shooting angle, wherein the camera shooting mechanism 7 comprises a base 71 and a camera shooting module 72 arranged on the base 71, and the base 71 is provided with radial displacement along a transparent transmission disc, horizontal displacement vertical to the radial displacement and vertical lifting displacement.
The position of the camera module 72 can be adjusted through the base 71, so that the requirements of different types of product specifications can be met.
Furthermore, the detection station 6 comprises a detachable strobe light source 9 for camera operations. Namely, the light source is realized without natural light source and natural light interference.
In a specific embodiment, the base detector station 61 is different from the type of camera mechanism of the selectively enhanced station 62, the type of strobe light source or the illumination angle,
namely, the detection difference exists between the basic detection machine position 61 and the selective reinforcement machine position 62, and different test effects are obtained through different types of camera mechanisms and different types of stroboscopic light sources or different irradiation angles.
In one embodiment of the present disclosure, the imaging mechanism of the base detection camera 61 is a color imaging mechanism, and the imaging mechanism of the enhancement camera 62 is a black-and-white imaging mechanism.
The concrete principle is explained:
it is known that there are large differences in imaging by different imaging mechanisms, and that passive elements typically detect defects by means of surface inspection, i.e. 2D inspection.
In the aspect of forming and developing, the color and the black and white are different, the angle of the projection light source is different, the brightness of the light source is different, and the like.
Therefore, it is difficult to realize all defect detection on one side by one machine position and matching with a light source.
In the scheme, aiming at special surfaces, such as the top surface and the bottom surface with coils, detection and screening can be performed by adopting multiple machine positions.
For such a surface, various machine position detection can be adopted, for example, a high-definition color camera and an annular vertical light source are adopted as a basic detection machine position 61, and a high-definition black-and-white camera and a planar photometry light source are adopted as a selective enhancement machine position 62, wherein the two are focused for detection. The basic detection machine position 61 mainly detects the damage, crack depth, rust color, copper exposure and size, the selective reinforcement machine position 62 mainly detects the damage outer edge, crack transverse and longitudinal length and size, and the detection is carried out through multi-machine position combination.
Of course, in this example, a high-definition color camera and an annular cohesive light source can be added as the second selective reinforcement machine 62, so as to provide more accurate reference of broken outer edges, crack outer edges and exposed copper, and comprehensive detection.
The irradiation angles of the base detection machine position 61 and the stroboscopic light source 9 of the selective reinforcement machine position 62 are different, and different detection image data are obtained through different irradiation angles, so that comprehensive analysis and detection are easy.
The depth of field of any image capturing mechanism 7 is adjustable, which is the prior art and will not be described here.
The angle adjusting mechanism 8 includes a triaxial adjusting base 81, and a photographing angle adjusting member 82 is provided on the triaxial adjusting base 81. The imaging angle adjuster 82 is a mirror or a triangular prism.
So designed, the shooting angles of all the detecting machine positions 6 can be perpendicular to the transparent transmission disc 21, and the sight line of each surface is converted through the adjusting positions of the shooting angle adjusting pieces 82, so that the design of the detecting machine positions 6 is easy.
In addition, aiming at the unexpected effect of a special electronic component, an electronic contact is arranged on any surface of the special electronic component, and the shooting angle of any property can be adjusted through the shooting angle adjusting piece 82, so that the shooting angle is vertical to the irregular electronic contact, and the situation of the root of the electronic contact can be detected. Specifically speaking, the angle can be adjusted manually to some electronic contact, and because the manual operation can have the tired damage of electronic contact, traditional check out test set can't detect this condition at all, and the check out test set of present case can detect this minutiae through adjusting the angle of making a video recording, satisfies actual demand.
Through the description, the electronic component detection equipment provided by the invention is innovatively designed with a selectively enhanced machine position, can perform multi-machine position detection on one side, can obtain comprehensive detection data at one time, is more accurate in detection, and meets detection efficiency. The camera shooting mechanism, the angle adjusting mechanism and the stroboscopic light source are all multi-axis adjustable structures, can be adaptively adjusted according to different passive elements, and particularly have wider applicability for detecting unconventional six surfaces. The whole design of the equipment is strict, the detection process is smooth, and the equipment is suitable for popularization and application.
