[0022] The detection system provided by the present invention is preferably equipped with a safety inspection machine and a performance test inspection machine, combined with an automatic loading and unloading system, to achieve fully automatic material circulation. The system has a high-precision automatic positioning function of ≤1mm, and can be seamlessly connected with a collaborative robot to ensure the accuracy and efficiency of material processing. The insulation and withstand voltage detection between the safety inspection machine and the production line are completely electrically isolated through the high-voltage output terminal to ensure the safety of electricity use and prevent the risk of current leakage or short circuit. The inspection machine is controlled by a programmable logic controller (PLC) and operates in conjunction with the loading and unloading robot.

Through the above design, the detection system provided by the present invention not only achieves a high degree of automation, but also greatly improves the detection accuracy and safety, while simplifying the processing process of unqualified products and improving the overall production efficiency.

[0023] Combine the following Figure 1 and Figure 2 The specific implementation manner of the detection system for the tilt sensor and the tilt sensor testing method of the present invention is described.

[0024] like Figure 1As shown, the present invention provides a detection system for an inclination sensor, including: a collaborative robot module, used to automatically transport the product to be tested to the detection station, and move the unqualified products to a temporary storage shelf; a safety inspection machine module, used to perform an insulation withstand voltage test on the product to be tested; a performance test machine module, used to perform a performance test on the product to be tested after the insulation withstand voltage test; a data management module, used to automatically save the detection data, and manage the transportation and storage of unqualified products; a visual system module, used to assist the precise operation of the collaborative robot.

[0025] Specifically, the detection system integrates automation and intelligent elements, with the collaborative robot module as the core, combined with the safety inspection machine, performance test machine, data management and vision system, to form a complete set of automated detection solutions. Through the automated handling operation of the collaborative robot, manual intervention is reduced and work efficiency is improved; the safety inspection machine ensures the electrical safety of the product; the performance test machine can accurately evaluate the key performance indicators of the inclination sensor; the data management module realizes the automated management of the detection data and the effective tracking of defective products; and the addition of the vision system further enhances the robot's operating accuracy and ensures the accuracy and reliability of the entire detection process.

[0026] In the actual operation of the detection system for inclination sensors, starting from the receipt of the products to be tested, the collaborative robot transports the samples to each inspection station in sequence according to the preset program. First, the safety inspection machine performs the insulation withstand voltage test to ensure that the product meets the safety standards. Subsequently, the performance test machine will conduct a more in-depth performance evaluation of these products that have passed the preliminary screening. During this period, all generated data will be recorded in real time and stored in the data management module for subsequent analysis and quality traceability. For products that fail to pass any test link, the system will automatically identify and classify them as unqualified products, and use collaborative robots to move them to temporary storage shelves for further processing. The entire process does not require a large amount of manual participation, which significantly reduces the risk of human error and improves the detection efficiency and reliability of the results.

[0027] According to the detection system for the inclination sensor of the present invention, the automatic loading and unloading of the products to be tested and the precise placement of unqualified products are realized through the cooperation of the collaborative robot and the visual system. The system integrates the insulation withstand voltage test with the electrical performance test, and can calibrate the inclination at different angles; the two test machines are efficiently connected with the help of the collaborative robot, and the flow of finished products is automatically completed after balancing the rhythm of each process. This system not only reduces manpower consumption, but also improves the finished product output and reduces the detection error rate through human-computer interaction, realizing a more intelligent operation process.

[0028] Preferably, according to a detection system for an inclination sensor of the present invention, the collaborative robot module includes: a transport unit for transporting the test products between different workstations; an operation unit for grabbing, placing and handling unqualified products; and a safety control unit for realizing collision detection and overload protection functions. The collaborative robot module realizes high-precision positioning and automated process management through an integrated visual system and intelligent algorithms.

[0029] Specifically, the collaborative robot module uses its transport unit to efficiently transport the products to be tested between the loading area, each test machine station and the temporary storage shelf, ensuring the smooth flow of materials. The operating unit is preferably equipped with an advanced end effector that can flexibly adapt to inclination sensors of different types and sizes, complete precise grasping and placement actions, and properly transport the identified defective products to the designated location. The safety control unit is preferably built-in with a variety of sensors and monitoring mechanisms, which can not only stop movement immediately in the event of an accidental collision to protect the safety of surrounding personnel and equipment, but also trigger protection measures in the event of an overload to prevent mechanical damage or performance degradation. In addition, the collaborative robot module preferably communicates with other components of the system. For example, the visual system provides it with real-time environmental information to help it perform precise operations, and the data management module is responsible for coordinating task scheduling to ensure the orderly progress of the entire detection process.

[0030] The transport unit may specifically include a rail system, a mobile platform, a conveyor belt, etc. These components ensure that the test items can be moved smoothly and efficiently between different workstations.

[0032] The safety control unit may specifically include collision sensors, torque sensors, emergency stop buttons, etc. The collision sensor can detect immediately when the robot makes accidental contact with the surrounding environment and trigger a stop command; the torque sensor is used to monitor the load borne by the robot arm or other moving parts, and once it exceeds the set threshold, the overload protection mechanism will be activated; the emergency stop button provides a quick response method for operators to quickly cut off the power supply or stop the operation of the robot in any emergency, thereby ensuring the safety of human-machine collaboration. In addition, it may also include software-level safety protocols and algorithms, such as speed limits, path planning optimization, etc., to further improve the safety of the system.

[0033] Furthermore, according to a detection system for a tilt sensor of the present invention, the collaborative robot module includes: an adjustment unit for fine-tuning the position of the object to be tested; and a positioning unit for positioning the object to be tested. Through the adjustment unit and the positioning unit, the collaborative robot module can ensure that the object to be tested maintains an optimal position in each test phase, thereby improving the accuracy and repeatability of the test.

[0034] Specifically, the adjustment unit can include micro-actuators, precision slides, rotating platforms, etc. These components allow for fine position and angle adjustments of the test object to meet the specific requirements of different inspection stations. For example, the micro-actuator can provide precise linear movement, while the rotating platform can adjust the angle of the inclinometer to ensure that it is in the best test posture.

[0035] The positioning unit may include a visual recognition device, a laser rangefinder, a mechanical limit device, etc. The visual recognition device uses a camera and image processing technology to identify the position and posture of the object to be tested, and provides feedback information to the adjustment unit to ensure that the object to be tested is placed correctly; the laser rangefinder can provide high-precision distance measurement to help determine the exact position of the object to be tested relative to the detection equipment; the mechanical limit device provides a physical reference point to ensure the consistency of each operation, especially in a test environment that requires high repeatability.

[0036] Preferably, according to a detection system for a tilt sensor of the present invention, the visual system module includes: an image acquisition unit for acquiring image information of the product to be tested; an analysis unit for analyzing the image information and providing a detection result; and a communication unit for communicating with the collaborative robot module to ensure synchronous operation. Through the image acquisition unit, the analysis unit, and the communication unit, the visual system module can achieve high-precision positioning and status monitoring of the tilt sensor, ensure accurate operation of the collaborative robot module, and provide real-time feedback of adjustment instructions to optimize the entire detection process.

[0037] Specifically, the image acquisition unit may include a high-resolution camera, an industrial camera, a light source system, etc. The high-resolution camera or industrial camera is used to capture clear images of the product to be tested, while the light source system provides stable lighting conditions to ensure that high-quality image information can be obtained in various environments. The analysis unit may include image processing software, machine learning algorithms, deep learning models, etc. The analysis unit can automatically identify and analyze feature points in the image, such as the shape contour and identification position of the tilt sensor, and then determine the position, posture and whether there are defects in the product to be tested. The communication unit may include a wireless network module (such as Wi-Fi, Bluetooth), a wired interface (such as Ethernet, USB), a PLC (programmable logic controller) interface, etc., to ensure fast and stable data exchange between the visual system module and the collaborative robot module, so that the results based on the image analysis can instantly guide the robot's actions, ensure the synchronization of operations between the two, and preferably support remote monitoring and data transmission, so as to facilitate integration into a wider range of automated detection systems.

[0038] Preferably, according to a detection system for an inclination sensor of the present invention, a special module for safety detection and a special module for performance test detection are integrated on the same platform or within the same work area; the high-voltage output terminal of the special module for safety detection is electrically isolated from the production line, and the production line is used for the human-machine collaborative assembly production of intrinsically safe inclination sensor products for mining. Specifically, by integrating the special module for safety detection and the special module for performance test detection on the same platform or within the same work area, the space occupied by the equipment can be significantly reduced, and the logistics path can be optimized. The electrical isolation between the high-voltage output terminal of the special module for safety detection and the production line is the key to ensuring operational safety. By using a dedicated isolation transformer, insulating materials and other electrical protection devices, it is possible to effectively prevent current leakage to the production line during high-voltage testing, protect the safety of operators, and also avoid electromagnetic interference to other equipment.

[0039] Further, according to a detection system for an inclination sensor of the present invention, a linkage mechanism is preferably provided between the safety detection machine module and the collaborative robot module, and the linkage mechanism includes: the safety detection machine module is embedded with a safety detection PLC, and the safety detection PLC has the function of insulation withstand voltage detection equipment failure and error alarm, and the collaborative robot module automatically adjusts the operation process according to the instructions issued by the safety detection PLC. Specifically, when any abnormal situation occurs during the safety detection process, such as voltage instability, test results exceeding the preset threshold or hardware failure, the safety detection PLC will immediately sound an alarm and transmit the error information to the collaborative robot module. After receiving these instructions, the collaborative robot module can automatically adjust the operation process, such as pausing the current operation, repositioning the product to be tested, or directly moving the problem product to a temporary storage shelf for subsequent processing.

[0040] On the other hand, a linkage mechanism is preferably provided between the performance test detection machine module and the collaborative robot module of the detection system, and the linkage mechanism includes: the performance test detection machine module is embedded with a performance test PLC, and the performance test PLC has the function of performance test equipment failure and error alarm, and the collaborative robot module automatically adjusts the operation process according to the instructions issued by the performance test PLC. Specifically, when any non-standard situation is found during the performance test, such as inaccurate output signal, long response time or other unqualified performance indicators, the performance test PLC will trigger an alarm and send relevant information to the collaborative robot module. Based on these instructions, the collaborative robot module can automatically take corresponding measures, such as marking and isolating defective products, adjusting test parameters for retesting, or notifying maintenance personnel to conduct inspections.

[0041] Through the above linkage mechanism, the detection system of the present invention realizes highly automated and intelligent management of the entire process from safety testing to performance testing, which not only improves the detection efficiency, but also enhances the system's flexibility and ability to cope with emergencies.

[0042] Preferably, according to a detection system for an inclination sensor of the present invention, the data management module includes a data storage unit and an alarm unit. The data storage unit is used to store the detection data, and may specifically include a database server, a cloud storage service, a local hard disk or a solid-state hard disk (SSD), and a backup system to achieve efficient management and long-term preservation of all detection records, operation logs and other information, and support subsequent data analysis and quality traceability. The alarm unit monitors the storage status of the temporary storage shelf according to the detection data, and sends an alarm signal when the goods are full. Specifically, it may include an audible and visual alarm, a text message or email notification system, a monitoring screen display, and a mobile application push notification to ensure that relevant personnel are notified in time to take action, to ensure the smooth operation of the production line and the effective management of defective products. Through the data storage unit, the data management module can not only ensure the integrity and availability of the detection data, but also improve the response speed of the system; and through the alarm unit, the data management module can immediately remind when the temporary storage shelf reaches the upper limit of capacity, enhance the real-time monitoring capability of the storage status, thereby effectively supporting the efficient operation and quality control of the entire detection system.

[0043] According to the detection system for inclination sensors of the preferred embodiment of the present invention, the system integrates a collaborative robot, a safety testing machine and a performance testing machine, aiming to realize the human-machine collaborative assembly production and multi-dimensional angle testing of mining intrinsically safe inclination sensor products.

[0044] Specifically, the system is equipped with an automatic loading and unloading system, including a safety test machine and a performance test machine, which can complete the automatic flow of materials. The collaborative robot is responsible for transporting the products to be tested from the loading area to each testing station, and automatically transports the unqualified products to the temporary storage shelf after the test is completed, ensuring that the entire process does not require human intervention.

[0045] Both the safety testing machine and the performance testing machine have automatic positioning function and can be efficiently connected with the collaborative robot. The positioning accuracy is controlled within 1mm, ensuring the position accuracy during the test process, thereby improving the reliability of the test results.

[0046] In order to ensure the safety of operators and avoid electromagnetic interference to other equipment, the high-voltage output end of the safety testing machine is completely electrically isolated from the production line. By using a dedicated isolation transformer and other electrical protection devices, a safe operating environment for the production line can be maintained even during high-voltage testing.

[0047] Each testing machine is controlled by an embedded PLC (Programmable Logic Controller) and has the function of detecting machine failure and error alarm. The collaborative robot module automatically adjusts the operation process according to the instructions issued by the PLC, such as pausing the current operation, relocating the product to be tested, or directly handling the problem product, ensuring the flexibility and response speed of the system.

[0048] All test data are automatically saved by the data management module to support subsequent data analysis and quality traceability. The data storage unit includes a database server, cloud storage service, local hard disk or solid-state drive (SSD), and a backup system to ensure data integrity and availability.

[0049] For products that fail the test, the collaborative robot will automatically move them to the temporary storage shelf for failed products. The temporary storage area is equipped with a full-stock alarm function. When the shelf reaches the upper limit of capacity, the alarm units such as the sound and light alarm, SMS or email notification system, monitoring screen display and mobile application push notification will promptly remind relevant personnel to take action to ensure the smooth operation of the production line.

[0050] The detection system for the inclination sensor of the above preferred embodiment not only improves the efficiency and accuracy of the detection of the intrinsically safe inclination sensor for mining, but also enhances the safety of operation and the intelligence level of the system, providing a solid technical guarantee for the production of high-quality products. In addition, the highly integrated and automated solution significantly reduces manual intervention, reduces the risk of human error, and improves the reliability and consistency of the overall production process.

[0051] The loading and unloading, and placement of defective products processes of the inclination sensor production line are realized by the cooperation of the collaborative robot and the visual system. The technical parameters of the collaborative robot are preferably shown in Table 1, and the machine vision technical parameters of the visual system are preferably shown in Table 2.

[0052] Table 1:

[0053] Table 2:

[0054] In actual applications, the collaborative robot transports the assembled products to be tested to the testing station, which is divided into two parts: insulation withstand voltage test and performance test.

[0055] The insulation and voltage withstand test is carried out on the product to be tested. The test machine completes the connection between the inclination sensor and the test machine through the movement of the electric cylinder and the plugging of the air cylinder. After the connection is completed, the test system is started and the insulation and voltage withstand test is carried out in accordance with the technical requirements of the inspection regulations. The test requirements for insulation resistance detection are shown in Table 3, and the test requirements for power frequency voltage withstand detection are shown in Table 4.

[0057] Table 4:

[0058] The collaborative robot will place the finished products that have passed the insulation and voltage withstand test on a special performance test machine and conduct testing in accordance with the technical requirements of the inspection procedures. The preferred test requirements for performance testing are shown in Table 5.

[0059] Table 5:

[0060] The tilt sensor testing method provided by the present invention is described below. The tilt sensor testing method described below and the detection system for the tilt sensor described above can be referred to each other.

[0061] The present invention also provides a tilt sensor testing method for controlling a detection system for a tilt sensor according to any one of the above embodiments. Figure 2 FIG. 1 is a flow chart of the tilt sensor testing method provided by the present invention, such as Figure 2 As shown, the method includes the following: Step 110: Transport the product to be tested to the insulation withstand voltage test station for insulation withstand voltage test. Specifically, the collaborative robot grabs the product to be tested from the loading area and places it precisely at the designated position of the safety inspection machine. The safety inspection machine automatically starts the insulation withstand voltage test through its built-in PLC control system to ensure that the high-voltage output end is completely electrically isolated from the production line to ensure safe operation.

[0062] Step 120: After the insulation withstand voltage test is completed, the tested product is moved to the performance test station. Specifically, once the insulation withstand voltage test is passed, the collaborative robot immediately moves the product to the corresponding station of the performance test machine according to the instructions issued by the PLC. During this process, the collaborative robot uses the visual system module for high-precision positioning to ensure that the product is accurately placed in the preset position for the next performance test.

[0063] Step 130, perform at least one of zero point calibration, parameter test and A-port test on the product to be tested according to the preset angle position. Specifically, the performance test detection machine connects to the product to be tested through electric cylinder movement and cylinder plug-in in accordance with the technical requirements of the inspection regulations, and then starts the test system. According to different test requirements, the system can perform zero point calibration (calibration of the initial position), parameter test (evaluation of various performance indicators of the sensor) or A-port test (checking the function of a specific interface) on the inclination sensor. These tests are designed to comprehensively evaluate the performance of the inclination sensor in an actual working environment.

[0064] Step 140: Save all test data. Specifically, all generated test data will be transmitted to the data management module in real time and stored in the data storage unit. The data storage unit may include a database server, a cloud storage service, a local hard disk or a solid-state drive (SSD), and a backup system to ensure data security and long-term availability. In addition, the data can also be used for subsequent quality analysis and traceability.

[0065] Step 150: For unqualified products to be tested, they are moved to the temporary storage shelf for unqualified products, and an alarm signal is issued when the temporary storage shelf is full. Specifically, if any unqualified products are found during the inspection process, the collaborative robot will automatically move these products to the temporary storage shelf for unqualified products according to the instructions of the PLC. At the same time, the alarm unit continuously monitors the storage status of the temporary storage shelf. When the shelf approaches or reaches the upper capacity limit, the alarm mechanism such as the sound and light alarm, SMS or email notification system, monitoring screen display and mobile application push notification will be triggered immediately to remind relevant personnel to deal with it in time to ensure the smooth operation of the production line.

[0066] Further, according to a tilt sensor testing method of the present invention, the steps of transporting the product to be tested to an insulation withstand voltage testing station and transferring it to a performance testing station include: Step 111, use the collaborative robot module to transport materials between different workstations. Specifically, the collaborative robot module is responsible for grabbing the test products from the loading area and accurately transporting them to the insulation withstand voltage test station where the safety testing machine is located. This process relies on the built-in transportation units of the collaborative robot, such as mobile platforms, guide rail systems or robotic arms, to ensure that the test products flow smoothly and efficiently between the various workstations. By working in collaboration with the visual system module, the collaborative robot can identify and avoid obstacles to ensure the safety and accuracy of the transportation path. In addition, the collaborative robot module is preferably equipped with an intelligent scheduling algorithm, which can optimize the transportation path according to real-time task requirements, reduce waiting time, and improve overall production efficiency.

[0067] Step 112, fine-tune the position of the product to be tested and position the product to be tested. Specifically, before placing the product to be tested at the inspection station, the collaborative robot will use its adjustment unit (such as micro-actuator, precision slide rail, rotating platform, etc.) to fine-tune the object to ensure that the product to be tested is in the best test position. Subsequently, the positioning unit (such as visual recognition system, laser rangefinder, mechanical limit device, etc.) intervenes to accurately position the product to be tested to meet the high-precision requirements required by the safety inspection machine and the performance test inspection machine. For example, the visual recognition system can capture the image of the product to be tested through a camera, and analyze its position and posture through image processing technology, and provide feedback information to the adjustment unit to ensure that the product to be tested is placed correctly. At the same time, the laser rangefinder can provide high-precision distance measurement to help confirm the exact position of the product to be tested relative to the inspection equipment, while the mechanical limit device provides a physical reference point to ensure the consistency of each operation.

[0068] Further, according to a tilt sensor testing method of the present invention, the step of saving all detection data includes: Step 141, save the test data through the data management module. Specifically, after receiving the test data transmitted from the safety test machine and the performance test test machine, the data management module immediately stores it in the data storage unit. The data storage unit may include a variety of storage media, such as database servers, cloud storage services, local hard disks or solid-state drives (SSDs), and backup systems to ensure the security, integrity and long-term availability of the data. The test records, operation logs and other information of each batch are recorded in detail to support subsequent data analysis and quality traceability. In addition, the data management module preferably also has real-time data processing capabilities, which can instantly analyze the test results, provide instant feedback, and provide suggestions for production line optimization.

[0069] Step 142, monitor the storage status of the temporary storage shelves according to the detection data. Specifically, the data management module is not only responsible for saving the detection data, but also monitors the storage status of the temporary storage shelves for defective products through a linkage mechanism with the alarm unit. The alarm unit continuously collects capacity information from the temporary storage shelves and compares it with the preset threshold. When the temporary storage shelves are close to or reach full load, the system will trigger an alarm signal, such as issuing a warning through an audible and visual alarm, or reminding relevant personnel to deal with it in time through text messages, emails, mobile application push notifications, etc. At the same time, the monitoring screen displays the usage of the temporary storage shelves to help managers understand the overall operation status in real time. This monitoring mechanism ensures that even under high-load production conditions, the storage of defective products can be effectively managed to avoid production line stagnation caused by full temporary storage shelves.
