[0019] Industrial products, such as washing machines, need to undergo quality inspections after final assembly to ensure that all components are assembled correctly and that the products can operate normally and smoothly. In the prior art, when inspecting these assembled products, it is necessary to rely on artificial senses for inspection. For example, a skilled worker needs to lie on top of a drum washing machine and use his ears to listen to see if there is any abnormality during the operation of the washing machine to determine if there is any abnormality. Although the manual method is simple to implement, the inspection efficiency is low, and the inspection results are greatly affected by subjective factors. The inspection standards vary from person to person, and the inspection accuracy will decrease as the skilled worker becomes tired. In order to increase the detection rate of product abnormalities, skilled workers may adhere to the strategy of "better to kill by mistake than to let go", resulting in the rework and disassembly of many qualified products, increasing production costs and reducing efficiency.

[0020] In addition, in some product manufacturing factories, such as the final assembly lines of large home appliance factories, efficient production of one drum washing machine is achieved every 15 seconds. In order to conduct product quality inspections efficiently and accurately, a large number of skilled workers are required, and the labor costs are too high.

[0021] The embodiments of the present invention provide a product quality inspection method, device and medium based on the industrial Internet. By arranging parallel and synchronously running conveyor belts in the product quality inspection device, and arranging a test bench, a test result acquisition device and a placement tray for automatically testing the product on the conveyor belts, and using the product quality inspection device to perform product quality inspection, the process of product quality inspection does not need to rely on artificial senses, is not affected by subjective factors and personnel status, and can improve the inspection efficiency and the accuracy of the inspection results when inspecting the product at a lower cost, and improve the abnormal detection rate, thereby avoiding abnormal missed detection due to incorrect product quality inspection results, and further avoiding abnormal operation of the product during use, which affects the product's service life and user experience.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments of the present invention described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0026] The first conveyor belt 1 is arranged in parallel with the second conveyor belt 2;

[0027] A placing tray 101 is fixedly arranged on the first conveyor belt 1, and a test table 201 and a test result acquisition device 202 are fixedly arranged on the second conveyor belt 2;

[0028] When performing quality inspection on the target product, the conveyor belt control device 3 is used to control the synchronous operation of the first conveyor belt 1 and the second conveyor belt 2, the placement pallet 101 is used to place the target product, the test table 201 is used to drive the target product for testing, the test sensor 4 is used to collect the sensor signal corresponding to the target product during the test process, and the detection result acquisition device 202 is used to obtain and determine the abnormal detection result of the target product based on the sensor signal.

[0029] Optionally, the target product is a washing machine, specifically a drum washing machine.

[0030] Specifically, the target product may also be a dryer or a wall-breaking machine.

[0034] Specifically, the positions of the test bench 201 and the test result acquisition device 202 on the second conveyor belt 2 are arranged corresponding to the placement tray 101 .

[0035] Specifically, the test sensor 4 may be a vibration sensor or a temperature sensor.

[0036] Optionally, the test sensor 4 is a magnetic sensor.

[0037] It is understandable that many industrial products are made of magnetic materials, such as refrigerators, washing machines, etc. The test sensor 4 is a magnetic sensor, which can be adsorbed and fixed on the product when testing the target product, so that the test process can be carried out conveniently and quickly.

[0038] Specifically, the test sensor 4 may also be other forms of sensors that can be fixed on a product.

[0039] Optionally, the test bench 201 can be specifically used to drive the rotation speed of the washing machine to gradually increase from 0 r / min to the maximum rotation speed, and then gradually decrease to 0 r / min.

[0040] Specifically, the maximum speed of the above-mentioned maximum speed can be set based on the maximum speed of the target washing machine in a normal working scenario.

[0041] Specifically, the washing machine is driven to be tested by the test bench rather than by the working control module of the washing machine, which can help to complete the effective test of the washing machine in the shortest time.

[0042] Optionally, the test bench 201 further includes a power supply module for providing power for the process of testing the target product.

[0043] Optionally, the detection result acquisition device 202 in the embodiment of the present invention includes: a sensor signal acquisition module and an abnormality recognition module, wherein the sensor signal receiving module is used to receive and acquire the sensor signal corresponding to the target product collected by the test sensor 4 during the test process, and the abnormality recognition module is used to determine the abnormal detection result of the target product based on the sensor signal.

[0044] Optionally, the above-mentioned abnormality identification module can be specifically used to obtain the spectrum data corresponding to the sensor signal to obtain test spectrum data, and determine whether the target product is an abnormal product based on the test spectrum data, and when the target product is an abnormal product, identify the abnormal type of the abnormal product to obtain an abnormality detection result.

[0045] Optionally, the above-mentioned abnormality identification module can be specifically used to convert the sensor signal into a digital sensor signal, perform noise reduction filtering on the digital sensor signal to obtain a filtered digital signal, and perform time-frequency conversion on the filtered digital signal to obtain the above-mentioned test spectrum data.

[0046] Optionally, the above-mentioned abnormality identification module can be specifically used to determine whether the above-mentioned target product is an abnormal product based on whether the spectrum distribution pattern of the test spectrum data conforms to the spectrum distribution pattern of the spectrum data corresponding to the normal product.

[0047] Optionally, the above-mentioned abnormality identification module includes a pre-trained product abnormality type identification model, and the above-mentioned process of identifying the abnormal type of the abnormal product includes: inputting the test spectrum data corresponding to the abnormal product into the pre-trained product abnormality type identification model; and obtaining the abnormal type of the abnormal product based on the test spectrum data through the target product abnormality type identification model.

[0048] Optionally, a target product whose corresponding spectrum distribution law conforms to the spectrum distribution law of the spectrum data corresponding to a normal product is determined as a normal product, and a target product whose corresponding spectrum distribution law does not conform to the spectrum distribution law of the spectrum data corresponding to a normal product is determined as a suspected abnormal product. Then, a product abnormality type recognition model is used to try to determine the abnormality type of the suspected abnormal product. If the suspected abnormal product can be determined as one of the preset multiple abnormal types, the product is determined to be an abnormal product. Otherwise, the product is determined as a product to be verified, so that the product can be retested and verified.

[0049] Specifically, the above-mentioned abnormal type recognition model can be a machine learning model, for example, a support vector machine model and a convolutional neural network model.

[0050] Specifically, for a drum washing machine, the abnormal types of the above-mentioned abnormal products may be, for example, bolts not tightened properly, bolts not tightened properly, wiring harness not tightened properly, counterweight block falling off, reinforcement not tightened properly, screws not tightened properly, or screws not tightened properly, etc.

[0055] Specifically, by displaying the abnormal detection results of the target product, the staff can intuitively and quickly know whether the target product is an abnormal product and the type of abnormal product, so as to sort, disassemble and inspect, check the source of the abnormality and complete product repair.

[0056] Specifically, the anomaly detection result of the target product may be sent directly to a client for easy viewing by the user without displaying it. Specifically, for example, the anomaly detection result may be sent to a mobile application terminal of the user.

[0060] Figure 2 It is another structural schematic diagram of the product quality inspection device based on industrial Internet provided in an embodiment of the present invention.

[0061] Optional, such as Figure 2 As shown, there are multiple trays 101 placed on the first conveyor belt 1.

[0062] Specifically, the number of the plurality of placement trays 101 and the spacing distances between the placement trays 101 can be set based on the running speed of the first conveyor belt 1 , the length of the first conveyor belt 1 , and the time required for testing the target product.

[0063] Optional, such as Figure 2As shown, the number of the test stations 201 on the second conveyor belt 2 can be set to be multiple, and the multiple test stations 201 can be set in a one-to-one correspondence with the multiple placement trays 101.

[0070] Specifically, when the target product is not being tested, the test sensor 4 may also be stored in a corresponding storage structure pre-set on the test bench 201 .

[0071] The embodiment of the present invention can further improve the test efficiency of testing the target product by arranging multiple groups of test mechanisms including placement trays, test tables and test result acquisition devices on the conveyor belt to meet the production speed of the production line.

[0072] Those skilled in the art can clearly understand that for the convenience and simplicity of description, only the division of the above-mentioned functional modules is used as an example for illustration.

[0086] Optionally, a target product whose corresponding spectrum distribution law conforms to the spectrum distribution law of the spectrum data corresponding to a normal product is determined as a normal product, and a target product whose corresponding spectrum distribution law does not conform to the spectrum distribution law of the spectrum data corresponding to a normal product is determined as a suspected abnormal product. Then, a product abnormality type recognition model is used to try to determine the abnormality type of the suspected abnormal product. If the suspected abnormal product can be determined as one of the preset multiple abnormal types, the product is determined to be an abnormal product. Otherwise, the product is determined as a product to be verified, so that the product can be retested.
