Description

The sandwich counting assembly

Technical field

The utility model relates to the technology of counting assembly, particularly relates to a kind of technology that adopts the optoelectronic scanning mode to add up the counting assembly of sandwich quantity.

Background technology

In the processing and manufacturing process, often need count sheet material materials such as paper, video disc, printed circuit board (PCB), sheet metals.Present this sheet material mostly adopts artificial counting or mechanical system counting, but adopts the cost of artificial counting very high, and spended time is many, and error is big.And adopt the speed of mechanical system counting slower, and can produce breakage when contacting with mechanical hook-up at a lot of sheet materials (as video disc), therefore also can't adopt the mechanical system counting.In addition, the method of counting of more existing employing visual pattern analytical technologies, owing to must use high-quality lighting device, high-precision video camera and image pick-up card, and complicated optical amplification system, therefore involve great expense, volume is bigger, is difficult in to be applied in neatly in the actual production to popularize on a large scale.

The utility model content

At the defective that exists in the above-mentioned prior art, technical problem to be solved in the utility model provides a kind of simple in structure, with low cost, adopt the optoelectronic scanning mode to its batch counting again after stacked sheet material, thereby can not damage measured object, and the sandwich counting assembly that counting rate is fast, counting precision is high.

In order to solve the problems of the technologies described above, a kind of sandwich counting assembly provided by the utility model is characterized in that: comprise the demonstration of optical sampling unit, the data processing that connects described optical sampling unit and control module, connection data processing and control module and the unit is set; Described optical sampling unit comprises light source, catoptron, camera lens, CCD element, the irradiate light that described light source penetrates is in the sandwich side, the reflected light of sandwich side is through being incident upon behind catoptron, the camera lens on the CCD element, data processing and control module comprise data collecting card and the control module that is connected described data collecting card, the electric signal that control module control data capture card produces after illumination the CCD element is sampled and is handled, and data result after treatment is resent to demonstration and the unit is set and shows.

Further, described Data Control module comprises single-chip microcomputer and control circuit.

Further, described demonstration and be provided with and be provided with the setting module that is used to be provided with working method in the unit, described control module is sampled to sandwich according to the set instruction control optical sampling of setting module unit.

The sandwich counting assembly that the utility model provides, owing to adopt the optical reflection principle, the optical sampling component structure is simple, compactness is easy to large-scale production, so its cost is lower; Owing to adopt the optoelectronic scanning mode that sandwich is carried out batch counting, so can not damage measured object; Because data processing and control module can be controlled the optical sampling unit same sandwich is repeatedly sampled in the short time at the utmost point, so its counting precision is also very high, its counting rate is also very fast.

Embodiment

Below in conjunction with description of drawings embodiment of the present utility model is described in further detail, but present embodiment is not limited to the utility model, every employing analog structure of the present utility model and similar variation thereof all should be listed protection domain of the present utility model in.

As shown in Figure 1 and Figure 2, a kind of sandwich counting assembly that the utility model embodiment is provided is characterized in that: comprise optical sampling unit 1, the data processing that connects described optical sampling unit 1 and control module 2, connect the demonstration of data processing and control module 2 and unit 3 is set; Described optical sampling unit 1 comprises linear light sorurce 4, catoptron 5, camera lens 6, linear CCD sense electronics optical element 7, the irradiate light that described light source 4 penetrates is in sandwich 8 sides, the reflected light of sandwich 8 sides is through catoptron 5, be incident upon behind the camera lens 6 on the CCD sense electronics optical element 7, data processing and control module 2 comprise data collecting card and the control module that is connected described data collecting card, the electric signal that control module control data capture card produces after illumination CCD sense electronics optical element 7 is sampled and is handled, and data result after treatment is resent to demonstration and unit 3 is set and shows.

Described Data Control module comprises single-chip microcomputer and control circuit.

Described demonstration and be provided with and be provided with the setting module that is used to be provided with working method in the unit, described control module is according to 8 samplings of the 1 pair of sandwich in the set instruction control optical sampling of setting module unit.

The utility model also comprises a platform that can move horizontally, can set move mode, the speed of platform by setting module, described control module moves according to the set instruction control platform of setting module, described optical sampling unit 1 is placed on the platform, and it can be moved horizontally with the tested relatively sandwich 8 of platform.

The utility model also can be placed on tested sandwich 8 on the platform, and optical sampling unit 1 is fixedly mounted in the cabinet, makes tested sandwich 8 to move horizontally with the relative optical sampling of platform unit 1.

During work, operating personnel set move mode, the speed of platform by setting module according to different situations, the data presentation mode, report to the police etc., control module moves according to the set definite value control of setting module platform, controlling the 1 pair of sandwich 8 in optical sampling unit simultaneously repeatedly samples, the electric signal that control module control data capture card produces after illumination CCD element 7 is sampled and is handled, after the data of repeatedly sampling are verified mutually, final count results delivered to show and unit 3 is set and show.

During sampling, the light that described linear light sorurce 4 sends is radiated at sandwich 8 sides equably, catoptron 5 is gathered behind the reflection ray of sandwich 8 sides a branch of very narrow light through projecting behind the camera lens 6 on the linear CCD element 7, because the end face of tablet is different with the light intensity that the slit between tablet is reflected, therefore on linear CCD element 7, produce different electric signal, control module control data capture card is sampled to the electric signal that CCD element 7 produces after illumination, again sampled data is handled the removal clutter, calculate the quantity of paper at last.

During data processing, with the height of stacked article as X-axis, its shading value is as Y-axis, the data that CCD gathered are plotted as a sinusoidal curve, its crest is a highlight regions, it is the end face of stacked article, trough is low bright area, it is the slit between stacked article, because the stain of stacked article end face, damaged, pile up a variety of causes such as influence of neat inadequately or material own to light, the resulting comparatively mixed and disorderly curve (as shown in Figure 3) that has a lot of interference noises often, therefore also must carry out Filtering Processing to data, such as carrying out repeatedly data acquisition (the per second kind can reach tens of to up to a hundred time) at same position,, calculate the crest quantity of the curve (as shown in Figure 4) that obtains after the Filtering Processing to obtain call parameter such as probability distribution density parameter or to adopt Kalman filtering method that the data curve is carried out Filtering Processing, can obtain the quantity of stacked article, because through repeatedly sampling and Filtering Processing, also through checking mutually, its computational solution precision is very high simultaneously.
