Description

Technical Field

[0001] This invention relates to the field of performance testing technology, specifically to an automated testing method for the physical and mechanical properties of children's toys. Background Technology

[0002] Automated testing of the physical and mechanical properties of children's toys is a key step in ensuring the safety and reliability of toys. Through automated means such as sensors, machine vision, and robotics, multiple standard tests can be completed efficiently, reducing labor costs and improving testing accuracy.

[0003] However, existing technologies cannot perform structural analysis on toys, making it impossible to conduct targeted mechanical and physical performance analysis. This makes it impossible to guarantee that toys will have high performance when they leave the factory, and it is also impossible to trace and repair the actual production based on performance testing.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to solve the problems mentioned above by proposing an automated testing method for the physical and mechanical properties of children's toys.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] An automated testing method for the physical and mechanical properties of children's toys is described below.

[0008] Toy loading involves conveying children's toys undergoing performance testing to the production line and marking them as the testing subjects.

[0009] Initial visual inspection involves detecting any defects in the subject. A high-definition camera captures the subject from all angles, and the captured images are then used to detect defects. If defects are found, the subject is reworked and repaired; otherwise, it is transported to the adjacent performance testing station.

[0010] Performance parameter acquisition and analysis: After entering the performance testing station, the parameters of the test subject are acquired and analyzed.

[0011] Data aggregation and judgment: The performance of the tested object is judged based on the aggregated collected data. If it passes the test, it is packaged and shipped out. If it fails the test, it is repaired based on the abnormal collected data.

[0012] In a preferred embodiment of the present invention, the visual preliminary inspection process is as follows:

[0013] The processing parameters of each part of the testing entity are statistically analyzed based on the production process of the testing entity;

[0014] Image acquisition of the detection subject through a high-definition camera;

[0015] According to the continuous image acquisition of the detection subject, the processing parameters corresponding to the same part of the same type of detection subject are obtained, and the processing defects of the current batch of detection subjects are inferred according to the comparison. If there is a numerical deviation in the processing parameters, it is inferred that there is a processing deviation in the current batch of detection subjects; if there is no numerical deviation in the processing parameters, it is inferred that there is no processing deviation in the current batch of detection subjects.

[0016] As a preferred embodiment of the present application, the processing parameters of the real-time detection subject are compared with the processing parameters set during the corresponding production process. If the real-time processing parameters exceed the error range based on the set processing parameters, it is inferred that the current detection subject is unqualified and needs to be repaired by rework;

[0017] In this case, if the current batch of detection subjects has a processing deviation, the processing parameters of the detection subjects are screened according to the error range based on the set processing parameters, and the detection subjects not in the error range are uniformly repaired by rework; if the current batch of detection subjects has no processing deviation, the current batch of detection subjects are uniformly repaired by rework;

[0018] If the real-time processing parameters do not exceed the error range based on the set processing parameters, it is inferred that the current detection subject is qualified; in this case, if the current batch of detection subjects has a processing deviation, the processing parameters of the detection subjects are screened according to the error range based on the set processing parameters; if the current batch of detection subjects has no processing deviation, the current batch of detection subjects are visually inspected and qualified.

[0019] As a preferred embodiment of the present application, the performance parameter acquisition and analysis process is as follows:

[0020] The detection subjects that pass the visual preliminary inspection are collected, and the detection subjects are divided into connected parts and independent parts according to the structure of the detection subjects, wherein the connected parts represent the connection areas of the independent parts of the detection subjects, and the independent parts represent the independent parts in the detection subjects. The detection subjects are subjected to external force by an industrial robot to test the mechanical properties of the connected parts;

[0021] During the external force application stage, the gap distance generated by the connection displacement of the seamless connection of the connected parts of the detection subjects and the shaking frequency caused after the generation of the gap distance are obtained, and the gap distance generated by the connection displacement of the seamless connection of the connected parts of the detection subjects and the shaking frequency caused after the generation of the gap distance are analyzed.

[0022] As a preferred embodiment of the present application, if the gap distance generated by the connection displacement of the seamless joint of the corresponding connection part of the detection subject exceeds the gap distance threshold, or the shaking frequency caused by the generated gap distance exceeds the shaking frequency threshold, it is inferred that the external force affects the mechanical properties; in this case, the external force is controlled to be reduced, and after the control is completed, if the gap distance cannot be repaired or the shaking frequency cannot be reduced, the connection part of the current detection subject is marked as low anti-interference and irreversible characteristic; on the contrary, if the gap distance decreases and the shaking frequency decreases, the connection part of the current detection subject is marked as low anti-interference and reversible characteristic.

[0023] If the gap distance generated by the connection displacement of the seamless joint of the corresponding connection part of the detection subject does not exceed the gap distance threshold, and the shaking frequency caused by the generated gap distance does not exceed the shaking frequency threshold, it is inferred that the external force has no effect on the mechanical properties; in this case, the external force is controlled to be increased until the gap appears, and then the external force is controlled to be reduced, and after the control is completed, if the gap distance is generated and recovered and the shaking frequency is increased and recovered, the connection part of the current detection subject is marked as high anti-interference and reversible characteristic; if the gap distance is not recovered or the shaking frequency is not recovered, the connection part of the current detection subject is marked as high anti-interference and irreversible characteristic.

[0024] As a preferred embodiment of the present application, the detection subject is simulated by using an industrial robot;

[0025] In the simulation use stage, each type of detection subject is analyzed, and according to the simulated use operation, the frequency of the external force generated by the contact of each independent part of the detection subject with the ground is obtained; if in the actual simulation use operation stage, the frequency of the independent part is not zero before the number of uses is supported by data, the independent part is marked as an external force direct contact surface; otherwise, it is marked as an external force indirect contact surface.

[0026] The contact points of the external force direct contact surface contacting the ground are obtained, and according to the contact frequency, the high-frequency points and the low-frequency points are divided; the continuous contact bearing frequency peak value generated by the high-frequency points without deformation and the contact bearing external force peak value generated by the low-frequency points without deformation are collected.

[0027] As a preferred embodiment of the present application, if the continuous contact bearing frequency peak value generated by the high-frequency points without deformation and the contact bearing external force peak value generated by the low-frequency points without deformation both exceed the corresponding set threshold, it is inferred that the external force direct contact surface performance detection is qualified, and is marked as high toughness physical characteristic; if the continuous contact bearing frequency peak value generated by the high-frequency points without deformation and the contact bearing external force peak value generated by the low-frequency points without deformation do not all exceed the corresponding set threshold, it is inferred that the external force direct contact surface performance detection is unqualified, and is marked as low toughness physical characteristic.

[0028] After the external force directly contacts the surface bearing the external force, the surface deformation frequency of the indirect contact surface of the external force is obtained, if the generated frequency exceeds the generated frequency threshold, it is marked as internal easy deformation characteristic, if the generated frequency does not exceed the generated frequency threshold, it is marked as internal difficult deformation characteristic.

[0029] As a preferred embodiment of the present application, the data summary determination process is as follows:

[0030] The detection subjects of low anti-interference and irreversible characteristics and low anti-interference and reversible characteristics are repaired, and the connection part is connected and reinforced;

[0031] Meanwhile, the detection subjects of high anti-interference and irreversible characteristics and high anti-interference and reversible characteristics are packaged for delivery, and the use scenarios are limited, that is, the use scenario of high anti-interference and irreversible characteristics bears a lower external force peak value than the use scenario of high anti-interference and reversible characteristics;

[0032] The detection subjects of low toughness physical characteristics are repaired, the material type of the external force directly contacting surface is replaced, or the stress point is dispersed by changing the structure of the external force directly contacting surface to reduce the influence of external force; the material type of the detection subject of internal easy deformation characteristics is replaced or an anti-external force structure is added inside;

[0033] The detection subjects of high toughness physical characteristics and internal difficult deformation characteristics are packaged for delivery.

[0034] Compared with the prior art, the present application has the following advantages:

[0035] 1、In the present application, the surface shape defects of the detection subject are inferred by defect detection, so as to affect the use efficiency of the detection subject after being put into use, and the defect range can be narrowed by video defect detection, so as to trace the corresponding production line process of production and processing, facilitate timely adjustment of the production line process, reduce the risk of continuous defects of the detection subject in the subsequent detection subject, and improve the production efficiency of the detection subject.

[0036] 2、In the present application, the performance parameters of the detection subject detected by visual preliminary inspection are collected; the performance of the detection subject is analyzed by collecting the performance of the detection subject, the detection intensity of the physical and mechanical performance of the detection subject is strengthened, it is ensured that the performance of the detection subject before delivery can meet the actual use demand, the mechanical performance of the detection subject is avoided to be abnormal, and the physical performance cannot be adapted to the use environment, the overall average use period of the same type of detection subject is shortened. BRIEF DESCRIPTION OF DRAWINGS

[0037] In order to facilitate the understanding of those skilled in the art, the present application will be further described below with reference to the drawings.

[0039] Figure 2 The method flow chart of the performance parameter collection and analysis step of the present application. DETAILED DESCRIPTION

[0040] In order to enable persons skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by persons skilled in the art without creative labor fall within the scope of protection of the present application.

[0041] Reference herein to“an embodiment” means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of the application. The appearances of the phrase that the phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are they necessarily mutually exclusive of other embodiments. It is explicitly contemplated that embodiments described herein can be combined with each other.

[0042] Please refer to Figure 1 As shown in the figure, the automatic detection method based on the physical and mechanical properties of children's toys is as follows:

[0043] Toy feeding: children's toys to be tested for performance are conveyed on the production line to form performance testing on the production line, reduce the detection time of a large number of children's toys, and mark the detection main body;

[0044] Visual preliminary inspection: the detection main body is detected for defects by high-definition cameras for all-around recording, and the recorded pictures are detected for defects; if there are defects, the work is returned for repair, and if there are no defects, the detection main body is conveyed to the adjacent performance test station;

[0045] Performance parameter collection and analysis: the detection main body is collected and analyzed for parameters after entering the performance test station;

[0046] Data summary and judgment: the performance of the detection main body is judged according to the collected data, and if it is qualified, it is packed and shipped, and if it is unqualified, it is repaired according to the abnormal collected data;

[0047] Further, the visual preliminary inspection step is used for defect detection of the detection subject, and through the defect detection, it is inferred whether the detection subject has surface defects that affect the use efficiency of the detection subject after being put into use. At the same time, through the video defect detection, the defect range can be narrowed to trace the corresponding production line process, so as to adjust the production line process in time and reduce the risk of continuous defects of the detection subject, thereby improving the production efficiency of the detection subject.

[0048] According to the production process of the detection subject, the processing parameters of each part of the detection subject are counted, wherein the processing parameters include the level of the spliced part of the detection subject and the shape of the material; wherein the shape of the material can be evaluated by the area or the occupied space of the specific shape.

[0049] The high-definition camera is used for image acquisition of the detection subject. It should be noted that in this link, in order to avoid the existence of shielding area in image acquisition, the clamp clamping is performed during the loading stage of the detection subject.

[0050] According to the continuous image acquisition of the detection subject, the processing parameters of the same part of the same type of detection subject are obtained, and the processing defects of the current batch of detection subjects are inferred according to the comparison. If there is a numerical deviation in the processing parameters, it is inferred that there is a processing deviation in the current batch of detection subjects; if there is no numerical deviation in the processing parameters, it is inferred that there is no processing deviation in the current batch of detection subjects.

[0051] The real-time processing parameters of the detection subject are compared with the processing parameters set during the corresponding production process. If the real-time processing parameters exceed the error range based on the set processing parameters, it is inferred that the current detection subject is unqualified and needs to be repaired. In this case, if the current batch of detection subjects has a processing deviation, the processing parameters of the detection subjects are screened according to the error range based on the set processing parameters, and the detection subjects not in the error range are uniformly repaired. If the current batch of detection subjects has no processing deviation, the current batch of detection subjects are uniformly repaired.

[0052] If the real-time processing parameters do not exceed the error range based on the set processing parameters, it is inferred that the current detection subject is qualified. In this case, if the current batch of detection subjects has a processing deviation, the processing parameters of the detection subjects are screened according to the error range based on the set processing parameters. If the current batch of detection subjects has no processing deviation, the current batch of detection subjects are visually preliminarily inspected.

[0053] Please refer to Figure 2As shown, the performance parameter acquisition and analysis step is used to acquire performance parameters of the inspection subject that has passed the initial visual inspection; the performance of the inspection subject is analyzed through the performance acquisition of the inspection subject, and the detection of the physical and mechanical properties of the inspection subject is strengthened to ensure that the performance of the inspection subject can meet the actual use requirements before leaving the factory, avoid the mechanical performance abnormality of the inspection subject and the physical performance being unable to adapt to the use environment, and shorten the overall average service life of the same type of inspection subject.

[0054] The detection subject that passes the initial visual inspection is collected, and based on its own structure, the detection subject is divided into connected parts and independent parts. The connected parts refer to the connecting areas between the various independent parts of the detection subject, such as the connecting area between the car body and the wheels in a toy car; the independent parts refer to the various independent parts within the detection subject, such as the car body or wheels in a toy car.

[0055] An industrial robot applies external force to the testing object to perform mechanical performance testing on the connecting parts;

[0056] During the external force application phase, the gap distance caused by the seamless connection displacement of the corresponding connecting part of the detection body and the resulting shaking frequency are obtained, and the gap distance caused by the seamless connection displacement of the corresponding connecting part of the detection body and the resulting shaking frequency are analyzed:

[0057] If the gap distance caused by the seamless connection of the corresponding connecting part of the detection subject exceeds the gap distance threshold due to displacement, or if the resulting wobbling frequency exceeds the wobbling frequency, it is inferred that external force affects the mechanical performance. In this case, the external force is reduced. If the gap distance cannot be repaired or the wobbling frequency cannot be reduced after the control is completed, the connecting part of the current detection subject is marked as having low anti-interference and irreversible characteristics. Conversely, if the gap distance decreases and the wobbling frequency decreases, the connecting part of the current detection subject is marked as having low anti-interference and reversible characteristics.

[0058] If the gap distance caused by the seamless connection of the corresponding connecting part of the detection subject does not exceed the gap distance threshold, and the shaking frequency caused by the gap distance does not exceed the shaking frequency, it is inferred that the external force has no effect on the mechanical properties. In this case, the external force is increased until a gap appears, and then the external force is reduced. After the control is completed, if the gap distance is generated and then recovered, and the shaking frequency increases and then recovers, the connecting part of the current detection subject is marked as having high anti-interference and reversible characteristics. If the gap distance is generated but not recovered, or the shaking frequency increases but not recovered, the connecting part of the current detection subject is marked as having high anti-interference and irreversible characteristics.

[0059] The detection subject is simulated by using an industrial robot, that is, the toy is simulated in an actual use scenario, such as picking up and putting down the toy;

[0060] In the use simulation stage, the detection subject of each type is analyzed, and the frequency of the contact of each independent part of the detection subject with the ground to generate an external force is obtained according to the simulated use operation. If the frequency of the independent part is not zero under the premise of the number of uses supporting the data in the actual simulated use operation stage, the independent part is marked as an external force direct contact surface, such as the outer surface of the toy shell. Otherwise, it is marked as an external force indirect contact surface. In this case, only the inner surface of the toy shell is an external force direct contact surface.

[0061] The contact point of the external force direct contact surface with the ground is obtained, and the contact point is divided into a high-frequency point and a low-frequency point according to the contact frequency. The continuous contact bearing frequency peak generated by the high-frequency point without deformation and the contact bearing external force peak generated by the low-frequency point without deformation are collected. The external force peak can be evaluated by height or moving speed during actual detection, which reduces the stress calculation intensity of the object movement during actual simulation.

[0062] If the continuous contact bearing frequency peak generated by the high-frequency point without deformation and the contact bearing external force peak generated by the low-frequency point without deformation both exceed the corresponding set threshold, it is concluded that the external force direct contact surface performance detection is qualified, and is marked as a high-toughness physical property. If the continuous contact bearing frequency peak generated by the high-frequency point without deformation and the contact bearing external force peak generated by the low-frequency point without deformation do not both exceed the corresponding set threshold, it is concluded that the external force direct contact surface performance detection is unqualified, and is marked as a low-toughness physical property.

[0063] After the external force direct contact surface bears the external force, the surface deformation frequency of the external force indirect contact surface is obtained. If the generated frequency exceeds the generated frequency threshold, it is marked as an internal easy deformation property. If the generated frequency does not exceed the generated frequency threshold, it is marked as an internal difficult deformation property.

[0064] The data summary determination steps are as follows:

[0065] The detection subjects with low anti-interference and irreversible characteristics and low anti-interference and reversible characteristics are repaired, and the connection parts are connected and reinforced.

[0066] Meanwhile, the detection subjects with high anti-interference and irreversible characteristics and high anti-interference and reversible characteristics are packaged for delivery, and the use scenarios are limited, that is, the use scenario of the high anti-interference and irreversible characteristics bears an external force peak lower than that of the high anti-interference and reversible characteristics.

[0067] The detection main body with low toughness physical properties is repaired, the material type of the direct contact surface of external force is changed or the stress point is dispersed by changing the structure of the direct contact surface of external force, and the influence of external force is reduced; the detection main body with internal easy deformation properties is replaced by changing the material type or increasing the anti-external force structure inside;

[0068] The detection main body with high toughness physical properties and internal difficult deformation properties is packaged and shipped; it needs to be explained that the detection main body packaged and shipped has corresponding properties.

[0069] In use, the toy is loaded, the child toy to be tested is conveyed on the production line, and is marked as a detection main body; visual preliminary inspection is performed on the detection main body, the detection main body is recorded in all directions by a high-definition camera, and defect detection is performed on the recorded picture; if there is a defect, it is repaired; if there is no defect, it is conveyed to the adjacent performance test station; performance parameter collection and analysis are performed on the detection main body after entering the performance test station; data summary and judgment are performed on the detection main body according to the collected data; if it is qualified, it is packaged and shipped; if it is unqualified, it is repaired according to the abnormal collected data.

[0070] The threshold or the preset value, the preset range and the like are set for result comparison and analysis, so as to determine whether it is good or bad, and the size of the threshold is determined according to sample data large model analysis and artificial experience combination to set input storage, and can be adjusted appropriately through seasonal or common influence conditions;

[0071] And the weight proportion coefficient, the influence factor and the like are set according to the influence of each parameter on the result, to allocate specific values to finally reflect the influence on the result, and are set by sample data large model analysis and artificial experience combination to set input storage, and can be adjusted appropriately through seasonal or common influence conditions.

[0072] The preferred embodiments of the above disclosed application are only used to help explain the application. The preferred embodiments do not describe all the details, nor limit the application to the specific embodiments. Obviously, according to the content of the specification, many modifications and changes can be made. The specification selects and describes these embodiments in order to better explain the principles and practical applications of the application, so that those skilled in the art can well understand and utilize the application. The application is limited by the claims and their entire scope and equivalents.
