The background auxiliary detection device that the card outward appearance detects
Technical field
The utility model relates to the background auxiliary detection device that a kind of card outward appearance detects.
Background technology
The card pick-up unit is normally used for detecting the face shaping of card, is used for distinguishing underproof card goods, elects so that underproof product picked up.Although existing card pick-up unit is the difference of delimiter card outward appearance accurately, but for the card with chip, it can not detect the tangent line on chip three limits accurately, concrete is that positive light reflection is so that detection camera is difficult to around the accurate detection chip whether tangent line is arranged.
The utility model content
For the deficiencies in the prior art, the purpose of this utility model is intended to provide a kind of background auxiliary detection device of card outward appearance detection, and whether its chip that can detect accurately on the card has tangent line on every side.
For achieving the above object, the utility model adopts following technical scheme:
The background auxiliary detection device that the card outward appearance detects, comprise conveying belt for delivery of card, be positioned at the conveying belt top upper light source and detection camera, be positioned at the conveying belt below over against the background detection accessory plate of detection camera and the lower light source that is positioned at background detection accessory plate below, be provided with the through hole that can pass for the light that lower light source penetrates on the background detection accessory plate.
This pick-up unit also includes a underframe, and conveying belt is installed on the underframe, and this underframe provides one the basis is installed for conveying belt.
One vertical beam along the short transverse extension is installed on the underframe, the dismountable crossbeam that is equipped with in the upper end of vertical beam, upper light source and detection camera are fixed on the crossbeam, so that adjust the position of upper light source and detection camera.
The beneficial effects of the utility model are:
Than prior art, the utility model not only can be used for the detection of card outward appearance, can also detect accurately the quality of tangent line on the card, and the accuracy rate that detects is higher, easy to maintenance, can be applicable to the detection of most card tangent line.

Embodiment
Below, by reference to the accompanying drawings and embodiment, the utility model is described further:
As shown in Figure 1, 2, be the background auxiliary detection device that a kind of card outward appearance of the utility model detects, it comprises conveying belt 1, upper light source 2, detection camera 3 and background detection accessory plate 4; A plurality of card A are arranged in order at conveying belt 1, conveying belt 1 is used for card A is carried along X-direction, upper light source 2 and detection camera 3 are positioned at the top of conveying belt 1, want to guarantee that the light of light source 2 shines on the card A, and reflex in the camera lens of detection camera 3 through card A, thus, so that detection camera 3 can detect the shape of card A; Background detection accessory plate 4 is positioned at the below of conveying belt 1, and over against detection camera 3, below this background detection accessory plate 4, be provided with light source (not shown), offer a plurality of through holes 41 on the background detection accessory plate 4, the light that lower light source penetrates passes from through hole 41, and shines the lower surface of card A.
Conveying belt 1 is installed on the underframe 5, utilizes a driven by motor; One vertical beam 6 along the short transverse extension is installed on the underframe 5, the dismountable crossbeam 7 that is equipped with in the upper end of vertical beam 6, upper light source 2 and detection camera 3 are fixed on the crossbeam 7, so that adjust the position of upper light source 2 and detection camera 3, adapt to the detection of different cards.
In conjunction with shown in Figure 3, during work, by driven by motor conveying belt 1, conveying belt 1 is carried card A along X-direction, when card A is transported to background detection accessory plate 4 top, detection camera 3 begins card A outward appearance is detected, at this moment, the light of lower light source passes through hole 41, the tangent line center of the upper chip of the card A that just in time shines, by the light transmission of card A, the tangent line of the upper chip of card A can significantly be shown, thereby make detection camera 3 can detect accurately the quality of the tangent line of the chip edge on the card A.
For a person skilled in the art, can make other various corresponding changes and distortion according to technical scheme described above and design, and these all changes and distortion should belong within the protection domain of the utility model claim all.
