When batch testing, the test process is controlled by human beings in sequence. Only one passenger special sender or receiver device can be tested at a time, and it takes about half an hour to test a single receiver device. When testing multiple devices in an order, multiple test systems are needed, and the simultaneous testing takes a long time and is low in efficiency.

[0003] At the same time, in order to improve the testing efficiency, some batch testing devices are provided in the prior art, which can test multiple products in batches, but most of them still need manual connection of the interfaces on the products and the test host. Some test devices set sockets matched with the product interfaces on the base station, and then connect the sockets to the test host, but such a method encounters some problems in actual process. First, it cannot be well confirmed whether the sockets have been inserted in place. In the case that it cannot be confirmed whether the sockets have been inserted in place, when there is no signal, it cannot be confirmed whether the connection problem is caused by the interface and the socket or the product itself.

DETAILED DESCRIPTION

[0052] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are part of, but not all of the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those of ordinary skill in the art without creative work should belong to the protection scope of the application.

[0053] The embodiment relates to an intelligent automatic test system for a passenger special sender and receiver, which comprises a control server 1, an automatic test subsystem 2, a robot subsystem 3, an information inputting subsystem 4 and a product frame 5 connected with the control server 1, and is used for realizing automatic test of the passenger special sender and receiver, detecting product performance indexes and determining whether the product is qualified. Figure 1 The robot subsystem 3 is also connected with the information inputting subsystem 4. The automatic test system is interacted with an external automatic transportation system (AGV automatic guided vehicle). Figure 2

[0054] The control server 1 runs a main control program and is communicatively connected with the automatic test subsystem 2, the robot subsystem 3, the information inputting subsystem 4, the product frame 5 and the AGV automatic guided vehicle. A database 11 is arranged on the control server 1 and is used for information interaction with other server data.

[0055] As shown in Figure 3 , the interaction of the control server 1 with other subsystems comprises the following.

[0056] The control server 1 sends a test request to the automatic test subsystem 2, the automatic test subsystem 2 uploads a test result to the control server 1 and stores the test result in the database 11.

[0057] The control server 1 sends a transportation request to the AGV automatic guided vehicle, and the AGV automatic guided vehicle uploads a transportation state to the control server 1.

[0058] The control server 1 sends an action instruction to the robot subsystem 3, and the robot subsystem 3 uploads an execution state to the control server 1.

[0059] The control server 1 sends an inputting instruction to the information inputting subsystem 4, and the information inputting subsystem 4 uploads identification information to the control server 1.

[0060] The system further comprises a user terminal communicatively connected with the control server 1, the control server 1 sends a detection application to the user terminal, and the user terminal feeds back a detection state to the user terminal.

[0061] The automatic test subsystem 2 of the track circuit product can automatically test at least ten passenger special senders and at least ten passenger special receivers at the same time, and the test efficiency is increased by more than 10 times compared with manual test. The automatic process eliminates human errors, and the standard deviation of test results is reduced to within 0.5%. Through cloud data analysis, the product yield is improved by 15%-20%. The whole process is unmanned, and more than 90% of manual intervention links are reduced. Test data are uploaded in real time during the test process, and a test report is automatically formed and output after the test is completed. Figure 9 ​, in the automatic test subsystem, around the robot subsystem 3, there are arranged receiver test equipment 21, receiver transfer platform 22, transmitter test equipment 23, transmitter transfer platform 24, test machine maintenance door 26, electrical control cabinet and its maintenance door 27, production line display screen 28, labeling machine and its material change door 29.

[0062] The assembled and debugged product 20 is placed on the product vehicle frame 5, and the product vehicle frame 5 is transported by an AGV automatic guided transport vehicle to a set position for the next inspection. According to the obtained product arrival information, it means that the robotic arm with appropriate load capacity in the robot subsystem 3 fixedly installs the bottom of the product 20 (transmitter, receiver) onto the detection base on the test equipment, and the robotic arm grabs the camera for information entry. Automated tests are carried out according to the set test items. During the test process, the socket test of the product is completed by the robotic arm, and the test results are stored in the control server 1. The robotic arm fixes and disassembles the detection base on the test equipment, meeting the requirement of testing ten products at a time. The principle block diagram of the automatic detection process of the track circuit product is as Figure 2 shown, and the actual on-site test layout is as Figure 8 shown.

[0063] The automatic test table subsystem 2 is responsible for completing all tests on product indicators, outputting a test report with a timestamp, and having the function of judging whether the product is qualified. The detection base of the test equipment is accessed, and after identifying the product barcode information, automatic tests are carried out to judge whether it is qualified and output the test report and results, as Figure 2 and Figure 4 shown.

[0064] The automatic test subsystem 2 includes transmitter test equipment 23 and receiver test equipment 21 (i.e., test bases), and each test base is independently designed with modular interfaces. The test base is built-in with a multi-channel signal acquisition module, supporting synchronous acquisition of parameters such as voltage, current, and frequency. There are detection bases deployed on the test equipment, and the number of detection bases is the same as the number of single trays on the product vehicle frame 5 to improve the detection efficiency. Optionally, the number of detection bases is not less than the number of single trays on the product vehicle frame 5.

[0065] The product to be tested 20 is grabbed onto the test equipment. Each detection base of the transmitter test equipment 23 and the dedicated passenger line receiver test equipment 21 is equipped with a position sensor, and the position sensor is connected to the control server 1 for detecting whether the dedicated passenger line transmitter and the dedicated passenger line receiver are inserted in place.

[0066] The automatic test subsystem 2 also includes a positioning and correction platform 25. After detecting the positioning pins of the product to be tested 20 on the positioning and correction platform, the positioning pin detection results are fed back to the control server 1. As Figure 7As shown, the bottom of the product base is provided with hooks 205, and the detection base 7 is provided with mounting holes 76 matched with the hooks 205, and the number of the mounting holes 76 is consistent with that of the hooks 205. Since the positions of the hooks 205 of the product to be tested may be slightly deviated, before the product to be tested is placed on the detection base of the test equipment, the positioning pins are positioned and corrected on the positioning and correction platform 25, and the specific process is as follows. Figure 9 As shown, the positioning and correction platform 25 is installed below a monocular camera for pin detection (i.e., detecting the positions of the hooks 205 at the bottom of the product). Before the product to be tested is tested, the monocular camera is used to detect the positioning pins of the product to be tested. The control server calculates the absolute coordinates of each hook 205 according to the detection result, and guides the robot to quickly adapt the hooks 205 at the bottom of the product to the mounting holes 76 on the detection base when the product to be tested is grabbed onto the test equipment. The pin detection improves the insertion accuracy of the product fixed to the test equipment, avoids multiple movements of the product to adapt the interface, and thus improves the automatic test efficiency. Preferably, the hooks 205 are L-shaped.

[0067] The traditional clamping jaw mechanism usually relies on rigid clamping force, which is easy to cause damage to the surface of the workpiece, and is difficult to adapt to the workpiece with uneven surface. Although the single suction cup device can adsorb the flat surface, the adsorption effect on the concave-convex surface is poor. The composite mechanism of the present application can combine flexible clamping, self-adaptive adsorption, self-adaptive pressure control clamping jaw and visual positioning, so that the clamping jaw and the suction cup work cooperatively to realize efficient, non-destructive and adaptive operation of grabbing the transmitter and the receiver, thereby improving the grabbing efficiency and applicability.

[0068] The robot subsystem 3 is a camera-jaw-suction cup composite grabbing mechanism based on visual assistance, which is responsible for fixing the product to the detection base, scanning and identifying the nameplate to obtain product information, pushing the detection base into the test equipment, and marking the tested product after testing. As shown in Figure 10 , the qualified certificate is automatically pasted to the corresponding position of the product after testing, and the warning label is pasted to the corresponding position of the unqualified product.

[0069] As shown in Figure 5 and Figure 6 , the robot subsystem 3 includes a visual positioning module, a clamping jaw mechanism, a suction cup mechanism and a cooperative control unit.

[0070] The visual positioning module includes an industrial camera and an image processing unit, which is used to identify the position of the workpiece in real time and feed back to the control server 1.

[0071] The clamping jaw mechanism adopts a self-adaptive pressure control device, and the clamping jaw is provided with a force sensor. The clamping force is monitored in real time through the force sensor, and the clamping pressure is dynamically adjusted according to the weight of the product to avoid surface damage.

[0072] Clamp jaw force calculation: according to the visual module to identify the workpiece weight (m), material friction coefficient (μ), safety factor (K), combined with the dynamic adjustment of the mechanical model.

[0073] Clamping force F = m g K1K2 / (2μ)

[0074] Where: K1 is the safety factor, usually 1.2-2.0; K2 is the working condition coefficient, considering the influence of acceleration.

[0075] Suction cup mechanism: configure vacuum suction device, suction port uses flexible material, which can fit the workpiece with low surface flatness.

[0076] Cooperative control unit: integrate visual data (workpiece parameters) and clamp jaw / suction cup control signal to realize multi-module cooperative action. If the workpiece surface is not flat enough to cause insufficient suction force of the suction cup, the clamp jaw auxiliary force is automatically increased; if the clamp jaw may damage the workpiece (such as thin-walled parts), the suction cup is preferentially used as the main force.

[0077] Test data is uploaded to the MES system (production information system) in real time, and AI algorithm is used to analyze historical data to generate equipment quality trend report.

[0078] Unqualified product data triggers early warning and feedback to the production end to optimize process parameters.

[0079] Based on historical test data, a fault prediction model of the repair transmitter or receiver is established to identify potential problems such as capacitor aging, optocoupler failure, and relay contact failure.

[0080] The system adopts intelligent automatic detection mode, follows unified control standards and detection standards, and uses a simpler and more convenient way to complete repeated and complex operations, while testing dozens of products, automatically storing backup test results, improving product detection efficiency, improving management benefits, and reducing the influence of human factors.

[0081] The automatic test of the system can meet the "black light workshop" requirements of the quality inspection department for such product testing and testing. All processes and procedures in the testing process are realized by unmanned, intelligent and automatic means. It can solve the problem of low consistency of manual testing, and can greatly improve the work efficiency of testing. Test data can also be shared with external systems to solve the "data island" formed after manual product testing. The large amount of data accumulated in the automatic testing process can be used for continuous optimization and improvement of product quality.

[0082] The system replaces traditional testing techniques and tools to realize automatic, information-based and intelligent testing capabilities and levels under new technical conditions, so as to improve enterprise operating efficiency and response ability to market demand and rapid changes.

[0092] 9. After the electrical test is completed (the receiver test time is about 2 hours, and the sender test time is about 1 hour), the base pneumatic device reversely pushes back the product;

[0093] 10. The automatic testing subsystem 2 transmits the test qualified or unqualified result to the control server 1.

[0094] After the test is completed, for qualified products, the control server 1 controls the labeling machine to print a qualified certificate (online printing) and paste the qualified certificate to the specified position on the product surface; the robot arm places the product with the pasted qualified certificate back to the original product rack 5, releases the AGV rack air clamp device, and sends a command to the AGV automatic guided vehicle to pick up; the product rack 5 loaded with the qualified product is transported to the finished product warehouse packaging line.
