The optical counting device

Technical field

The utility model relates to a kind of optical devices, what be particularly related to is that a kind of line style light emitting source that relies on is from the bottom to top or from top to bottom or from left to right or from right to left, tabular assembly with incident angle irradiation inclination one angle, and rely on video camera to be taken to obtain the quantity that a reflected image is supplied with the tabular assembly of image identification unit judges, reach the efficient height, cost is low and the accurate purpose of number of computations.

Background technology

General printed circuit board (PCB) and tabular assemblies such as discs or other sheet products on the market all need number of computations in processing procedure or before dispatching from the factory, in order to the carrying out of successive process, or convenient tabular pack so that the quantity energy correct consign to manufacturer or client.

And the method major part of calculating tabular component count use at present is with manpower a slice a slice number of computations, or methods such as the weight of the tabular assembly of collocation measurement plural pieces or measurement stack height, and then learn behind the tabular assembly of plural pieces divided by monolithic weight or thickness, so convert and try to achieve the quantity of whole tabular assembly, and contrast mutually with measuring the quantity that weight or stack height tried to achieve, and then obtain a tabular component count after the contrast mutually with artificial calculating.

Yet, but there is the problem of makeing mistakes easily to produce with artificial number of computations, and with suitable slow of the speed of artificial number of computations, so efficient is poor; Moreover the suitable height of cost of labor does not quite meet the consideration of cost yet with artificial number of computations now.And each tabular assembly all has certain weight and thickness error, therefore it is also unreliable to measure the weight or the stack height of tabular assembly and the quantity Calculation method that converted, and how to develop the optical counting device that a kind of efficient height, the low and accurate number of computations of cost, be the ardent expectation of dealers in fact.

Have in view of that, the utility model designer is based on user and dealer's demand, is being engaged in the experience accumulation that this industry designs for many years, and creates a kind of optical counting device, for the industry utilization.

Summary of the invention

Prior art shortcoming in view of the above, fundamental purpose of the present utility model provides a kind of optical counting device, thereby reaches the efficient height, cost is low and the accurate purpose of number of computations.

For achieving the above object, the utility model provides a kind of optical counting device, is the counting that is applied in tabular assembly, includes:

At least one support body includes the base that at least one is put for tabular assembly, when described tabular assembly is seated in base, is to present to tilt an angle;

At least one line style light emitting source is seated in the tabular assembly of base with an incident angle in order to irradiation, and forms the space at tabular assembly lateral margin and arrange or jagged reflected light;

At least one video camera in order to the aforesaid reflected light of photographing, and obtains a reflected light image;

At least one image identification unit, include at least one main frame, be carried in image identification software in the main frame with at least one, described main frame is to electrically connect aforesaid video camera, and aforesaid reflected image is to input in the main frame, and relies on the image identification software to judge the quantity of tabular assembly;

At least one output unit is to electrically connect aforesaid image identification unit, in order to show quantity.

Advantage of the present utility model is, can improve existing defective, has the advantage of efficient height, the low and accurate number of computations of cost.

Embodiment

Relevant for technology, means that the utility model adopted and reach effect, lift preferred embodiment now and cooperate graphic detailed description as after, believe when can by must go deep into and concrete understanding.

Please cooperate and consult Fig. 1 to Fig. 2 and first embodiment shown in Figure 5, optical counting device of the present utility model is applied in the counting of tabular assembly 6, includes:

At least one support body 1, include a base 11 for tabular assembly 6 storings, with a back up pad 12 that extends up by base 11 1 lateral margins, described back up pad 12 is equipped with a spacing hole 121, back up pad 12 is to form an angle with base 11 in addition, when making tabular assembly 6 be seated in base 11, be to present the inclination certain angle.

At least one line style light emitting source 2, be with from the bottom to top an irradiating angle n towards 121 irradiations of aforesaid spacing hole, so irradiation is arranged in the tabular assembly 6 in the spacing hole 121, and forms first reflected light 21 that arrange the space at tabular assembly 6 lateral margins; And described irradiating angle n can be by between ° angle, 0 ° of angle to 90.

At least one video camera 3 is arranged on aforesaid spacing hole 121 the place aheads, in order to aforesaid first reflected light 21 of photographing, and obtains a reflected image 31.

At least one image identification unit 4 includes a main frame 41, with an image identification software 42 that is carried in the main frame 41; Described main frame 41 is to electrically connect aforesaid video camera 3, and video camera 3 to take the reflected image 31 that obtains be to input in the main frame 41, and rely on image identification software 42 to judge the quantity of above-mentioned first reflected light 21; In view of the above, obtain the quantity result 61 of a tabular assembly 6.

At least one output unit 5 is to electrically connect aforesaid image identification unit 4, and receives aforesaid quantity result 61, in order to present the quantity of tabular assembly 6.Its mode that presents quantity can present in order to modes such as demonstration, report and printings, and output unit 5 also can be made as devices such as display, printer and voice announcer.

See also Fig. 3 to second embodiment shown in Figure 5, second embodiment of optical counting device of the present utility model is identical with first example structure and array mode, and different being in first light emitting source of implementing 2 is that the tabular assembly in spacing hole 121 6 shines from the bottom to top, and the light emitting source 2 of second embodiment is by tabular assembly 6 irradiations of side in spacing hole 121, and form second reflected light 22 as shown in Figure 4, and rely on image identification software 42 to judge the quantity of second reflected light 22.

Special in addition one carry be, among first embodiment, light emitting source 2 is if be incident upon tabular assembly 6 sides in the mode that focuses on, and the light of reflection will have the dizzy phenomenon of opening and produce, this phenomenon when judging quantity, causes the computing machine misjudgment for image identification software 42 quite easily.Therefore line style light emitting source 2 of the present utility model is to use unfocused mode to be incident upon tabular assembly 6 in the spacing hole 121, the light of reflection is concentrated, not having the dizzy phenomenon of opening produces, make image identification software 42 more accurate when judging tabular assembly 6 quantity, also therefore be not easy to cause the erroneous judgement of computing machine; Among second embodiment, 2 of light emitting sources are with type of focusing polishing.

To sum up institute is old, and embodiment of the present utility model really can reach the use effect of expection, has really met the important document of patent defined, files an application in accordance with the law.

More than explanation is novel just illustrative for this; and it is nonrestrictive; those of ordinary skills understand; under the situation of the spirit and scope that do not break away from following claims and limited; can make many modifications; change, or equivalence, but all will fall in the protection domain of the present utility model.
