Referring to fig. 2, fig. 2 is a flow chart of an exemplary embodiment of the product testing method of the present invention.
The product testing method provided in the embodiment is suitable for an automatic testing platform, and can automatically perform color detection when a product is tested, so as to confirm whether a product to be tested can normally operate in different operating states according to a color detection result, or check whether the appearance design of the product to be tested meets preset requirements or not according to the color detection result. Because the color detection is not required to be carried out manually, and the color detection is also not required to be carried out in a point-to-point mode by adopting the optical fiber, the automation level of the automatic test platform is improved, and the operation is more convenient when the automatic test platform is used for carrying out product test.
It should be noted that the automated testing platform to which the product testing method in this embodiment is applied includes not only the needle bed and the upper computer, but also the intelligent terminal. This intelligent terminal can be the terminal equipment that has the image acquisition function such as smart mobile phone or intelligent flat board, and in the application, can be connected with the host computer with wired or wireless mode and realize data communication, preferably connect through WIFI in this embodiment. The upper computer is used as a control end capable of directly sending a control command, can be communicated with the intelligent terminal, and can control the connection state of the needle bed and a product to be tested; the needle bed is used as a non-standard test auxiliary fixture which can test on-line components by utilizing electrical performance so as to check production defects and poor components, the connection state between a test probe on the needle bed and a test point on a product to be tested can be controlled by an upper computer, and then the product to be tested is switched to different running states by changing the connection state of different test points so as to test different running states of the product to be tested.
Specifically, in this embodiment, the product testing method includes the following steps:
step S10: when a product to be tested is connected with a needle bed of the automatic test platform, receiving a state setting instruction of the product to be tested sent by an upper computer;
when carrying out automated test to the product that awaits measuring, in order to realize the automated inspection to the product colour that awaits measuring, can be connected with the needle bed of automatic test platform with the product that awaits measuring earlier, there are a plurality of running state at the product that awaits measuring, and when there is the product that awaits measuring to have the change on some colours under the different states, need carry out the colour detection to the product that awaits measuring corresponding different running state to whether the product that detects can normal operating under the running state of difference. The product to be detected is a product needing color detection, and can be a product provided with an LED, such as: whether the on-off state of the LED lamp is abnormal or not can be analyzed by carrying out color detection on the LED lamp, and then whether the running state of a product to be tested is abnormal or not can be analyzed; or the product may be a product with a part having a combined color, for example, a red part of a certain product is on the left, a blue part of the certain product is on the right, whether the part is installed incorrectly can be determined by performing color detection on the product to be tested, and for example, color test can be performed on PCBA (Printed Circuit Board + Assembly) to determine whether there is a missing part or whether the wire rod is used incorrectly, etc. Moreover, the product to be tested may include only one product, or may include a plurality of products at the same time. For example, a preset number of PCBA boards with the same number can be spliced to form a PCBA jointed board, and thus, each PCBA board is provided with a power indicator light; during the test, power indicator on every PCBA board all needs to inspect the LED state, and the accessible intelligent terminal shoots the LED of predetermineeing the number simultaneously, carries out state detection to the LED of predetermineeing the number simultaneously, realizes automatic test.
On one hand, the color detection can realize the consideration of different running states of the product to be detected, and also can realize the detection of whether the appearance profile of the product is qualified (if the product is not detected, whether the position of the part is staggered, whether the wiring is wrong, and the like). Therefore, in an embodiment, before receiving a state setting instruction of a product to be detected sent by an upper computer, a detection item corresponding to the product to be detected needs to be determined, and targeted detection is performed according to an item type corresponding to the detection item. Therefore, the detection items of the product to be detected can be set according to the product type of the product to be detected, such as the product related to the running state change, the detection items can be set to be state detection, the product not related to the state change, and the detection items can be set to be contour detection.
When the detection item is contour detection, contour detection operation can be performed on the product to be detected. The specific process of performing the contour detection operation on the product to be detected may be: firstly, determining a test surface required to be detected of a product to be detected and contour areas corresponding to different test surfaces. Then, when different test surfaces are tested, the product to be tested can be automatically turned over according to the set test sequence, and color data of each test point in the corresponding outline area is collected. Because the state change is not involved, the acquired color data does not need to be dynamically acquired, and only one image needs to be acquired by different test surfaces, and a plurality of images can be acquired simultaneously for the sake of safety; in addition, the collected outline area can be the whole outline area of the product to be tested, or the outline area where one or more components on the product to be tested are located, that is, one test surface may correspond to a plurality of outline areas; and then, uploading the collected color data corresponding to the different contour areas to an upper computer, and comparing the color data corresponding to the different contour areas with the pre-stored color data by the upper computer to determine whether the appearance contour of the product to be detected meets the preset requirement or not. If so, testing the next contour region until the last contour region; and if not, marking the product to be detected as unqualified.
When the detection item is in state detection, different running states corresponding to the product to be detected can be switched by sending a state switching instruction through the upper computer. Therefore, after the product to be tested is connected with the needle bed of the automatic test platform, whether a state setting instruction sent by the upper computer is received or not needs to be detected in real time, so that the state setting instruction of the product to be tested sent by the upper computer is received, and the running state of the product to be tested is set or switched. The state setting instruction can automatically switch the running states of the products to be tested according to each running state corresponding to the products to be tested and the execution sequence of each running state which are preset; or after testing an operating state, setting a state parameter corresponding to the next operating state, that is, after testing an operating state, receiving a state setting instruction sent by the upper computer again. The state setting instruction can be set manually or by default, and different types of products to be tested are tested by different test platforms.
Step S20: setting the state information of the product to be detected in response to the state setting instruction, and determining a detection area corresponding to the state information;
after receiving a state setting instruction of a product to be tested sent by an upper computer, a state parameter corresponding to the state setting instruction may be determined, and the state parameter may include: the number information and the position information of the test points, and various test parameters such as voltage, current and load corresponding to different test points.
And if the product to be tested only has one running state, responding to the state setting instruction, and directly setting the state parameters corresponding to the state setting instruction as the running parameters of the product to be tested when the product to be tested is tested so as to set the state information of the product to be tested as the state information corresponding to the state setting instruction.
If the product to be tested has multiple operation states, the connection position of the test point corresponding to each operation state, the voltage, the current, the load and the like corresponding to different test points are different, so that the current state parameter of the product to be tested needs to be switched to the state parameter corresponding to the state setting instruction, at this time, the connection state of the test points (such as the position, the number and the like of the electrified test points) and the test parameters such as the voltage, the current, the load and the like connected with each test point can be changed in response to the state setting instruction, and the state information of the product to be tested is switched.
Before collecting color data, in order to ensure the validity of the collected color data, a detection area corresponding to different state information of a product to be detected needs to be determined so as to collect color data of each test point in the detection area. In an embodiment, a user may autonomously set the location information and the quantity information of the test points on the automatic test platform, and thus, the test area corresponding to the state information of the product to be tested may be determined according to the test point setting operation triggered by the user on the automatic test platform.
Specifically, the step of determining the detection area corresponding to the state information of the product to be detected may be: the method includes the steps that an operation instruction sent by an upper computer is detected in real time, if a test point setting operation which is sent by the upper computer and corresponds to the current state information of a product to be detected is received, the test point setting operation can be responded, the test point corresponding to the test point setting operation is set as a target test point corresponding to the current state information, and an area containing all target test points is used as a detection area corresponding to the state information.
Step S30: acquiring color data of each test point in the detection area, which is acquired by the intelligent terminal, and reporting the color data to an upper computer so that the upper computer can confirm a test result of a product to be tested according to the color data;
the intelligent terminal comprises an image acquisition device (such as a camera), has an image acquisition function, and can acquire color images of all test points in the detection area through the intelligent terminal. However, because different products that await measuring are under different state information, the detection area that needs the collection can be different, and the object that corresponds the collection also can be different, and intelligent terminal is when gathering the colour image in the detection area, and corresponding adjustment also need be made to the shooting parameter that corresponds the setting. Therefore, image acquisition parameters of the intelligent terminal can be determined according to the current state information of the product to be detected and the determined detection area; and then, adjusting the shooting parameters of the intelligent terminal according to the determined image acquisition parameters to acquire color data acquired by the intelligent terminal according to the adjusted shooting parameters. Such as: under the current state, when the detection area is small, the focal length can be properly adjusted to carry out amplification treatment; when the discrimination between the detected object and the background color in the detection area is not large, the contrast can be properly improved; when the detection environment is dark, the exposure level can be properly increased. The image acquisition parameters are image parameters which need to be adjusted when color data of a product to be detected under current state information are acquired, and can comprise focal length, brightness, exposure, contrast and the like, and the shooting parameters, particularly the image parameters when the intelligent terminal is used for shooting, at least comprise the image acquisition parameters.
On the other hand, because the test time and the test frequency corresponding to different states may be different, in order to ensure the validity of the collected color data, the test time of the product to be tested and the refresh frequency of the color data collected by the intelligent terminal need to be set, so as to avoid the lack of reliability of the collected color data due to insufficient test time or too high refresh frequency which cannot effectively capture the color change. Therefore, in an embodiment, the test time of the product to be tested and the refresh frequency of the intelligent terminal when collecting the color data are also set according to the current state information of the product to be tested, and further, the color data of each frame of image collected by the intelligent terminal according to the set refresh frequency is obtained within the set test time. Meanwhile, it is also required to ensure that the acquired color data of each frame image includes the color data of each test point in the detection area.
After color data acquired by the intelligent terminal are acquired, the acquired color data can be reported to an upper computer, the upper computer processes the reported color data, for example, if a product to be detected is a charging power panel, the charging power panel is provided with 1 LED, the LED is in long-light state to supply power to the outside, and is in flashing state (1 second is on and 1 second is off) to indicate charging, and is not in light state to indicate shutdown; the intelligent terminal continuously acquires the image of each frame, extracts color data of each frame corresponding to the LED position, immediately reports the extracted color data to the upper computer, and if the upper computer needs to know the LED state, the upper computer needs to analyze the color data reported in real time so as to analyze the LED state.
Here, when the intelligent terminal reports the color data, the color data can be reported in a plurality of data formats, such as RGB formats or HSV formats, so that the upper computer can analyze different applications conveniently, and the application expansion can be performed conveniently. Therefore, in an embodiment, before the color data is reported to the upper computer, a data format of the color data corresponding to the current state information is determined, then the intelligent device is controlled to collect the color data of each test point in the detection area, and the collected color data is reported to the upper computer in the determined data format, so that the upper computer can analyze the received color data normally, and misjudgment on a test result when the color data cannot be analyzed normally is avoided, and thus an automatic test effect is influenced.
In an embodiment, the process of processing the color data by the upper computer may be: the method comprises the steps of intercepting color data of corresponding points on a color picture through an image recognition and processing technology, then comparing the intercepted color data with corresponding color data in a database, or classifying the intercepted color data through a color analysis model which is trained in advance and corresponds to a product to be detected, and the like, and analyzing whether the product to be detected can normally run under the current state.

step S13: acquiring color data of each test point in the detection area, which is acquired by the intelligent terminal, and reporting the color data to an upper computer;
step S14: detecting whether a state switching instruction sent by an upper computer is received;
step S15: if so, responding to the state switching instruction, switching the state information of the product to be detected to the next state information, and executing the step of determining the detection area of the product to be detected corresponding to the state information;
step S16: and if not, executing the step of receiving the state setting instruction of the product to be tested sent by the upper computer when the next product to be tested is connected with the needle bed of the automatic test platform.
In this embodiment, when the product to be detected has a plurality of states, the upper computer may determine whether the next state is needed for detection. Therefore, after the color data of each test point in the detection area collected by the intelligent terminal is obtained and reported to the upper computer, whether a state switching instruction sent by the upper computer is received or not can be further detected. If a state switching instruction sent by an upper computer is received, switching the state information of the product to be detected to the next state in response to the state switching instruction, and continuously executing the step of determining the detection area of the product to be detected corresponding to the state information after the state switching; if the state switching instruction sent by the upper computer is not received, whether the next product to be tested exists or not can be further detected, and if the next product to be tested exists and is connected with the needle bed of the automatic test platform, the step of receiving the state setting instruction of the product to be tested sent by the upper computer is continuously executed.
In an embodiment, after the color data is reported to the upper computer, the upper computer can confirm the test result of the product to be tested according to the reported color data, and the upper computer can further feed back the test result to the intelligent terminal so as to prompt the test result at the intelligent terminal side. Therefore, after receiving the test result sent by the upper computer, if the received test result indicates that the product to be tested is abnormal in the current state, the intelligent terminal can be used to output a first prompt message to prompt that the current state information is abnormal and prompt the reason of the possible abnormality, such as the fact that the image acquisition parameters of the intelligent terminal are not correct, the fact that the data format is not correct, the fact that the test time is not enough, and the like, so as to timely perform corresponding abnormality processing according to the first prompt message; if the received test result indicates that the product to be tested can normally operate in the current state, the intelligent terminal can be used for outputting second prompt information to prompt that the product to be tested operates normally in the current state, so that whether a step of receiving a state switching instruction sent by the upper computer is received or not is further executed, and then when the state switching instruction sent by the upper computer is received, the state information of the product to be tested is switched.
Of course, when the test result is that the current state is abnormal, the current state can be selectively switched to the next state, and the next state is continuously detected, so that the abnormal state is specifically processed.
This embodiment carries out the state switching through the host computer to the product that awaits measuring for the user can independently select whether to need to detect next state based on the production demand, so, can only trigger state switching instruction when needs carry out the state switching, and when need not carrying out the state switching, directly detect next product of awaiting measuring, can save the detection of unnecessary state switching and unnecessary state, make the automated inspection process more nimble, can improve the production efficiency of producing the line.
