Referring to fig. 1 and 2, an embodiment of the present application provides a detection method for weighing components of a package. The detection method mainly comprises the following steps:

s110, the number of the components of the packaging box is increased step by step and sequentially weighed.

S120, weighing the front component to form a front weight.

S130, adding a new component to the front component to form a rear component, weighing the rear component to form a rear weight, and subtracting the front weight from the rear weight to form a new weight of the new component.

And S140, forming the total weight of the packaging box by the sum of the weight of the component obtained by the first weighing and all the newly added weights, and judging that the packaging box is qualified when the previous weight and all the newly added weights meet the requirements.

The packing box mainly includes parts such as reagent bottle, inner liner, calibrator, outer box, lid and description, in the packaging box's equipment in-process, all places reagent bottle and calibrator on the inner liner generally, and reagent bottle and calibrator are the container both, and the reagent bottle is used for holding reagent, and the calibrator can be tubular structure and is used for depositing liquid. The amount of reagent in the reagent bottle must be accurate and the amount of liquid in the calibrator must be accurate, for example, in case the amount of reagent in the reagent bottle and the amount of liquid in the calibrator are low, this will not make the package put on the market, i.e. the package is a defective product. After placing both the reagent bottle and the calibrator on the inner liner, the inner liner carrying the reagent bottle and calibrator is then placed in the outer box, and then the cover and instructions are placed in the outer box and the outer box is capped, and finally assembled to form a complete package.

For the traditional detection method, a method for weighing the total weight of the packaging box is generally adopted, after the reagent bottle, the inner liner, the calibrator, the outer box, the cover body and the instruction book are all assembled to form the packaging box, the total weight of the packaging box is weighed, and when the total weight of the packaging box meets the design requirement, the packaging box is considered to be a qualified product. However, this method has the following drawbacks: on the one hand, when the weight of one part forming the packaging box is larger than that of the other parts under the condition that the part forming the packaging box is neglected, even if the total weight of the packaging box meets the design requirement, the packaging box is actually an unqualified product. On the other hand, in the case of a complete package, if some of the components are more heavy than the design requirements and some of the other components are less heavy than the design requirements, this will produce a counteracting effect, which will also make the total weight of the package meet the design requirements, but the package is also practically a reject product. For example, when the amount of the reagent or the liquid contained in the key components such as the reagent bottle and the calibrator is low relative to the design requirement, and the weight of the components such as the outer box, the cover body and the instruction book is high relative to the design requirement, the offset is formed, so that the total weight of the packaging box meets the design requirement, and obviously, the assembled packaging box is an unqualified product in view of the relatively low amount of the reagent or the liquid. Therefore, the detection accuracy of the detection method is low.

For the detection method in the above embodiment, in each weighing process, the new weight of the new component can be clearly known, so that the new weight meets the design requirement, that is, the weight of each component can meet the design requirement, and finally, the total weight of the packaging box formed by assembling the components with the weight meeting the design requirement meets the design requirement, so that the assembled packaging box is a qualified product. In other words, the total weight of the packing box meets the design requirement, and the weight of each part of the packing box also meets the design requirement, so that the detection precision of the detection method on the packing box is improved. The weight of the single component can not meet the design requirement on the premise that the total weight of the packaging box meets the design requirement.

The number of the newly added weights is at least two, for example, after the first part is weighed, a second part is newly added on the first part, and the weight of the first part is subtracted from the total weight obtained by weighing the first part and the second part, so that the newly added weight of the second part is obtained, and at the moment, the newly added weight is one. And then, adding a third component to the assembly formed by the first component and the second component, and subtracting the weight of the first component and the second component from the total weight obtained by weighing the assembly formed by the first component, the second component and the third component, thereby obtaining the new added weight of the third component, wherein the new added weight is two. By analogy, the number of newly added weights may also be increased depending on the number of parts comprised in the package.

After the front weight of the front part and the rear weight of the rear part are obtained, the difference between the front weight and the rear weight may be calculated by the PLC control program, thereby obtaining a value of the new added weight. Of course, when the preceding weight is acquired, the PLC control program may be made aware of the weight as the preceding weight of the preceding component by scanning the two-dimensional code on the preceding component. And the two-dimensional code on the rear part is scanned, so that the PLC control program knows that the weight is the rear weight of the rear part, and finally the PLC control program is convenient to calculate the value of the newly increased weight according to the difference between the front weight and the rear weight, thereby improving the calculation precision of the PLC control program and finally improving the detection precision of the packaging box.

During weighing, when the preceding weight is not satisfactory, this means that the preceding part is not satisfactory and the preceding part is removed. And when the newly added weight is not in accordance with the requirement, the rear part group is taken away. So effectively avoid there being unqualified part of weight in the packing carton, improve the detection precision of packing carton.

The number of the parts included in the front part is one or more, the number of the parts included in the rear part is one or more, and the number of the parts included in the newly added part is one or more. In view of the relatively large tolerance range of the weight of certain components, a plurality of components can be weighed together, so that the weighing times are reduced, and finally the weighing efficiency is improved on the basis of not affecting the detection precision.

Specifically, the detection method may be performed by the detection apparatus 20, and the detection apparatus 20 includes a first stage 211, a first weighing unit 212, a first output unit 213, a second stage 221, a second weighing unit 222, a second output unit 223, a third stage 231, a third weighing unit 251, a third output unit 252, and a discharging stage 260, which are sequentially disposed. The detection device 20 mainly performs the following steps:

in the first step, an inner liner is placed on the first stage 211, and a reagent bottle containing a reagent is placed on the inner liner. The inner liner carrying the reagent bottles is then input to a first weighing unit 212, and the first weighing unit 212 first weighs the reagent bottles and the inner liner to form a first weight. If the first weight meets the design requirement, the inner liner carrying the reagent bottle is input to the second stage 221. If the first weight does not meet the design requirement, the inner liner carrying the reagent bottles is input to the first output unit 213 to output the entire detecting device 20. Of course, during the weighing process, the first weighing unit 212 may scan the two-dimensional code on the inner liner, so that the PLC control program knows that the first weight is the weight of both the reagent bottle and the inner liner.

In the second step, when the inner pad carrying the reagent bottle is input to the second stage 221, three calibration samples containing liquid are put in different positions on the inner pad. The inner liner carrying the reagent bottle and the calibrator is then input to the second weighing unit 222, and the second weighing unit 222 performs a second weighing of the reagent bottle, the inner liner and the calibrator to form a second weight, and the PLC control program subtracts the first weight from the second weight to obtain the weight of the calibrator. If the new weight represented by the calibration material meets the design requirement, the inner liner carrying the reagent bottle and the calibration material is input to the third stage 231. If the new weight represented by the calibration material does not meet the design requirement, the inner liner carrying the reagent bottle and the calibration material is input to the second output unit 223 to output the whole detection device 20. Of course, in the weighing process, the second weighing unit 222 can scan the two-dimensional code on the inner liner, so that the PLC control program knows that the second weight is the weight of the reagent bottle, the calibrator and the inner liner. Obviously, for a first weight and a second weight, the first weight is the front weight and the second weight is the rear weight. The inner liner carrying the reagent bottles is the front part, while the inner liner carrying the reagent bottles and calibrator is the rear part.

Third, when the inner liner carrying the reagent bottle and the calibrator is input to the third stage 231, the inner liner carrying the reagent bottle and the calibrator is put into the outer box, and the cover and the instructions are put into the outer box. Then, the outer box containing the reagent bottle, the calibrator, the inner liner, the cover and the instruction book is input to the third weighing unit 251, and the third weighing unit 251 performs third weighing on the reagent bottle, the calibrator, the inner liner, the cover, the instruction book and the outer box to form a third weight, and the PLC control program subtracts the second weight from the third weight to obtain the weights of the cover, the instruction book and the outer box. If the new weight represented by the cover, the instruction sheet and the outer box meets the design requirement, the outer box containing the reagent bottle, the calibration material, the inner liner, the cover and the instruction sheet is input to the blanking table 260, so that the outer box is covered to be assembled into a qualified packing box. If the added weight represented by the cover, the instruction sheet and the outer case does not meet the design requirement, the outer case containing the reagent bottle, the calibrator, the inner pad, the cover and the instruction sheet is input to the third output unit 252 to output the whole detection device 20. Of course, in the weighing process, the third weighing unit 251 can scan the two-dimensional code on the outer box, so that the PLC control program knows that the third weight is the weight of the reagent bottle, the calibrator, the inner liner, the cover, the instruction book and the outer box. Obviously, for the second weight and the third weight, the second weight is the front weight and the third weight is the rear weight. The inner liner carrying the reagent bottle and the calibrator is the front part, and the outer box containing the reagent bottle, the calibrator, the inner liner, the cover and the instruction book is the rear part.

In another embodiment, the detection method further includes the step of performing image acquisition by the visual detection unit 240 to determine the number, color and position of the components included in the part of the newly added components. The viewing angle detection unit may be a CCD detection unit.

For the traditional detection method for the total weight of the packaging box, when the total weight of the packaging box meets the design requirement, the packaging box is considered as a qualified product, so that the detection precision of the detection method is affected. For example, in the case where a certain component constituting the packing box is neglected, the other component not belonging to the packing box is assembled instead of the component, and the weight of the other component not belonging to the packing box is just equal to the weight of the component, even if the total weight of the packing box meets the design requirements, the packing box is actually a defective product. For another example, in the case that the color, number and position of the component parts of the package are wrong, the package is usually observed by a manual method, but the error phenomenon is difficult to be effectively perceived by the manual method, and even if the total weight of the package meets the design requirement, the package is actually an unqualified product.

With the detection method of the above-mentioned another embodiment, in view of the fact that the visual detection unit 240 can perform image acquisition, the number, color and position of the components included in the part of the newly added components are accurately determined, so as to ensure that the formed package is a qualified product.

Specifically, the detection method of the other embodiment may be performed by the detection apparatus 20 of the other embodiment, and the detection apparatus 20 includes a first stage 211, a first weighing unit 212, a first output unit 213, a second stage 221, a second weighing unit 222, a second output unit 223, a third stage 231, a visual detection unit 240, a third weighing unit 251, a third output unit 252, and a blanking stage 260. The third object-carrying platform comprises a left object-carrying platform 2312 and a right object-carrying platform 2311. The first stage 211, the first weighing unit 212, the first output unit 213, the second stage 221, the second weighing unit 222, the second output unit 223, the right stage 2311, the visual detection unit 240, the left stage 2312, the third weighing unit 251, the third output unit 252, and the discharging stage 260 are sequentially disposed. The detection device 20 mainly performs the following steps:

Third, when the inner liner with the reagent bottles and the calibrator is loaded onto the right stage 2311, the inner liner with the reagent bottles and the calibrator is put into the outer box. The outer box containing the reagent bottle, the calibrator and the inner liner is input to the visual detection unit 240, and the visual detection unit 240 detects the placement positions of the calibrator and the reagent bottle, and when the positions are incorrect, the positions can be adjusted. The visual detection unit 240 can also detect the color and the number of the calibration standards, and can be replaced again when the color of the calibration standards does not meet the design requirements, and can be increased or decreased when the number of the calibration standards does not meet the design requirements.

Third, the outer case containing the reagent bottles, the calibrator and the inner pad is input from the visual inspection unit 240 to the left stage 2312, and then the cover and the instructions are put into the outer case. Then, the outer box containing the reagent bottle, the calibrator, the inner liner, the cover and the instruction book is input to the third weighing unit 251, and the third weighing unit 251 performs third weighing on the reagent bottle, the calibrator, the inner liner, the cover, the instruction book and the outer box to form a third weight, and the PLC control program subtracts the second weight from the third weight to obtain the weights of the cover, the instruction book and the outer box. If the new weight represented by the cover, the instruction sheet and the outer box meets the design requirement, the outer box containing the reagent bottle, the calibration material, the inner liner, the cover and the instruction sheet is input to the blanking table 260, so that the outer box is covered to be assembled into a qualified packing box. If the added weight represented by the cover, the instruction sheet and the outer case does not meet the design requirement, the outer case containing the reagent bottle, the calibrator, the inner pad, the cover and the instruction sheet is input to the third output unit 252 to output the whole detection device 20. Of course, in the weighing process, the third weighing unit 251 can scan the two-dimensional code on the outer box, so that the PLC control program knows that the third weight is the weight of the reagent bottle, the calibrator, the inner liner, the cover, the instruction book and the outer box. Obviously, for the second weight and the third weight, the second weight is the front weight and the third weight is the rear weight. The inner liner carrying the reagent bottle and the calibrator is the front part, and the outer box containing the reagent bottle, the calibrator, the inner liner, the cover and the instruction book is the rear part.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application.
