Description

Technical Field

[0001] This invention belongs to the field of electrical product testing technology, specifically relating to an integrated high-voltage switching machine. Background Technology

[0002] In the manufacturing process of various electrical products, continuity and high-voltage withstand performance are core indicators for measuring product quality and safety, directly affecting the reliability and stability of the product during subsequent use, as well as the personal and property safety of users. Therefore, continuity and high-voltage testing of electrical products is an indispensable and critical testing step in the production process.

[0003] Currently, the industry mostly uses separate testing equipment to address such testing needs. This means that continuity testing and high-voltage testing are performed by different dedicated devices. This testing mode requires multiple transfers, positioning, and clamping of the product to be tested between different devices. This not only increases the workload of operators, extends the overall testing cycle, and reduces production testing efficiency, but also easily leads to positioning deviations due to multiple clamping, affecting the accuracy of the test results. Furthermore, the operation process of traditional separate testing equipment is relatively cumbersome, requiring operators to have a high level of professional skill. Operators need to be proficient in the operating procedures and parameter settings of different devices; otherwise, operational errors are prone to occur, leading to incorrect test results, equipment failure, or even safety accidents. In addition, some traditional testing equipment lacks a comprehensive safety protection mechanism, making it difficult to provide full protection for the personal safety of operators in dangerous testing processes such as high-voltage testing, posing significant safety hazards. Moreover, traditional testing equipment has poor compatibility, usually only adapting to the testing of a single model or a few models of products. When dealing with products of various specifications and shapes, frequent changes of testing fixtures and adjustments to equipment parameters are required, further reducing testing efficiency and increasing production testing costs. At the same time, it is difficult to centrally record, store and view various information and results during the testing process, which is not conducive to subsequent quality traceability and data analysis, and is not conducive to the optimization of production processes and the improvement of product quality. Summary of the Invention

[0009] Preferably, the fixing base is connected with several copper positioning pins, and detection sensors for detecting the positioning of round and square products are respectively set in both ends of the fixing base, so as to realize the secondary accurate positioning of the product and detect the installation position of products with different shapes, thus avoiding detection errors.

[0010] Preferably, the probe holder is evenly distributed with a number of probe terminals and probes to realize the circuit connection between the probes and the detection and control module, ensure stable transmission of detection signals, and complete multi-point detection of the product.

[0011] Preferably, guide rails are installed on both sides of the chassis, and a protective cover is slidably connected between the two sets of guide rails. A stroke cylinder is installed inside the chassis and on both sides of the guide rails. The piston rod of the stroke cylinder is connected to the protective cover, which can realize the automatic lifting and lowering of the protective cover to form a closed protective space and ensure the safety of the operator during testing.

[0012] Preferably, the surface of the chassis is evenly distributed with two rows of test indicator lights, and the surface of the chassis is also equipped with a touch screen and a high-voltage tester, which are used to provide real-time feedback on the operation and testing status of the equipment, and to realize parameter setting, data display and high-voltage detection signal supply.

[0013] Preferably, a three-color alarm light is installed on the top of the chassis, and an emergency stop switch is provided at the front of the chassis, which can promptly report abnormal equipment status and can stop the machine in an emergency to ensure the safety of equipment and personnel.

[0014] Preferably, the bottom of the chassis is rotatably connected to several casters, which are used to enable flexible movement and stable parking of the equipment, facilitating equipment installation, debugging and workshop layout adjustment.

[0015] Compared with the prior art, the beneficial effects of the present invention are: (1) By integrating continuity testing (multimeter mode, ST-03 tester mode), high voltage testing, spline position detection, grounding resistance measurement and qualification mark printing / stamping functions into one unit, it replaces the traditional separate testing equipment. It eliminates the need to transfer products between multiple devices and clamp them multiple times, greatly reducing the workload of operators, shortening the testing cycle, and improving production testing efficiency. At the same time, the integration of the equipment reduces the space occupied by the equipment, lowers the equipment procurement, installation and maintenance costs, and adapts to the needs of large-scale production.

[0016] (2) A multi-positioning structure is set up, with copper positioning pins and arc / square auxiliary limit blocks to achieve precise product positioning. The three-jaw chuck and magnetic switch ensure reliable product clamping and avoid the impact of clamping deviation on the test results. It is equipped with a mistake-proof detection switch and a product positioning detection sensor, which can realize the mistake-proof identification of products with the same appearance but different specifications. At the same time, it can detect the product installation status, eliminate the detection error caused by the wrong placement or misplacement of the product, and improve the accuracy and consistency of the test results.

[0017] (3) The equipment is equipped with a comprehensive safety protection system, including a protective cover, a stroke cylinder, an emergency stop switch, and a high-voltage test. In dangerous situations, the protective cover is closed to form a closed protective space, and the safety light curtain monitors the dangerous area in real time.

Detailed Implementation

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0023] This invention provides, for example Figure 1-10The high-voltage switching integrated machine shown includes a chassis 1 for integrating and installing various functional modules, providing a stable installation foundation and ensuring the overall structural strength of the equipment, as well as a power source module and a positioning and clamping unit integrated inside the chassis 1 to realize the core functions of power supply and precise positioning and clamping of the product. The power source module, serving as the core power support for all components of the equipment, includes a power supply unit, a compressed air unit, and an air source treatment unit. The power supply unit provides continuous and stable power support to the various electrical components, detection modules, and control modules of the equipment, ensuring the precise and orderly operation of each electrical component. The compressed air unit provides sufficient and stable pneumatic power to all pneumatic actuators of the equipment, meeting the needs of various pneumatic actions such as clamping, lifting, and pushing. The air source treatment unit performs integrated processing on the compressed air output from the compressed air unit. It removes impurities from the air by filtering, adjusts the pressure to a level suitable for the working pressure of the pneumatic components by reducing pressure, and lubricates and protects the pneumatic components by treating them with oil mist. This ensures the cleanliness and pressure stability of the compressed air, preventing impurities and pressure fluctuations from damaging the pneumatic components, extending the service life of the pneumatic components, and ensuring the smoothness and reliability of pneumatic actions. The positioning and clamping unit is used to accurately position and firmly clamp products 11 of different shapes and specifications, providing a stable testing benchmark for subsequent on / off and high voltage testing. It includes a three-jaw chuck 2 for clamping and fixing the product, and a fixed base 3 for mounting the three-jaw chuck and auxiliary limiting components. The three-jaw chuck 2 is fixedly installed at the bottom of the fixed base 3, which can realize the quick clamping and releasing of the product and adapt to the clamping requirements of products with different diameters. The fixed base 3 has an arc-shaped auxiliary limiting block 4 and a square auxiliary limiting block 5 detachably connected to its two sides, which are used to adapt and switch according to the shape difference of the product 11 to realize the auxiliary limiting of round products and square products respectively, to prevent the product from shifting or shaking during clamping and improve the positioning and clamping accuracy. It also includes a support base 6 for mounting the load-bearing test execution component. The support base 6 is fixedly connected inside the chassis 1, serving as the installation reference for the pressure test component and ensuring structural stability during the test process. A pressure cylinder 7 for providing pressure power is fixedly mounted on the support base 6. A pressure seat 8 for mounting the probe seat is fixedly connected to the piston rod end of the pressure cylinder 7. The bottom of the pressure seat 8 is detachably connected to the probe seat 10 for mounting the test probe via a quick-change positioning pin 9. The extension and retraction of the pressure cylinder 7 drives the pressure seat 8 and the probe seat 10 to rise and fall synchronously, achieving precise contact or separation between the probe seat 10 and the product 11 to be tested, thereby completing the continuity and high-pressure withstand performance test of the product 11. The quick-change positioning pin 9 enables the quick disassembly and replacement of the probe seat 10, adapting to the testing needs of different product specifications and improving testing flexibility and efficiency.

[0024] The support base 6 also integrates a fault-prevention detection switch 12 and a resistance detection contact point 13. The fault-prevention detection switch 12 is used to identify products with the same appearance but different specifications, preventing the use of products with inconsistent specifications for testing, which could lead to testing errors or equipment malfunctions, thus improving the accuracy and safety of the testing. The resistance detection contact point 13 is used to make precise contact with the grounding terminal of the product, working with the testing module to complete the measurement of the product's grounding resistance, achieving comprehensive testing of the product's grounding performance. The fixing base 3 is rotatably connected to the inside of the chassis 1 via a rotating shaft, allowing for the rotation and adjustment of the fixing base 3 and the product it holds. The section facilitates comprehensive testing of different parts of the product by the testing module. Inside the housing 1, a servo motor 14 for providing rotational power is fixedly installed via a mounting base 16. The output shaft of the servo motor 14 is fixedly connected to the rotating shaft of the fixed base 3 via a coupling 17. The precise rotation of the servo motor 14 drives the coupling 17, the rotating shaft, and the fixed base 3 to rotate synchronously, realizing precise adjustment of the product testing angle, ensuring the comprehensiveness and accuracy of the testing points. The coupling 17 can buffer the impact force during the motor rotation process, protect the motor and the rotating shaft, and improve the stability and reliability of the transmission.

[0025] A push cylinder for providing pushing power is also fixedly installed on one side of the bottom of the fixed base 3. An automatic stamping assembly 15 is fixedly connected to the piston rod end of the push cylinder. The automatic stamping assembly 15 is used to automatically print or stamp a qualified mark on the designated position of the product after the product has passed the inspection, so as to realize the rapid marking of qualified products, which facilitates the subsequent sorting, circulation and quality traceability of products. There is no need for operators to manually mark, reducing the workload of manual labor, improving the efficiency of production and inspection, and ensuring the uniformity and standardization of the marking.

[0026] A magnetic switch 18 is fixedly installed on the surface of the three-jaw chuck 2. The magnetic switch 18 is used to detect the clamping status of the three-jaw chuck 2 in real time, accurately determine whether the product is firmly clamped and whether the clamping force meets the detection requirements. If the clamping is not in place or abnormal, a signal can be sent in time and the equipment alarm can be triggered to prohibit the subsequent detection process, so as to avoid detection deviation, product damage or safety accidents caused by loose clamping. A shaft positioning hole 19 is opened in the middle of the three-jaw chuck 2. The shaft positioning hole 19 is used to cooperate with the product shaft to achieve precise positioning, further improving the coaxiality and positioning accuracy of product clamping, and providing a guarantee for detection accuracy.

[0027] The fixed base 3 is fixedly connected with several copper positioning pins 20 for precise product positioning. The copper positioning pins 20 have good conductivity and wear resistance, and can accurately cooperate with the product positioning holes to achieve secondary positioning of the product, further eliminating the deviation during the product clamping process and ensuring the accurate alignment of the detection points. The fixed base 3 is equipped with detection sensors 21 embedded in its two ends. The two sets of detection sensors 21 are used to detect the installation status of round and square products, respectively, and can provide real-time feedback on whether the product is placed in place. If the product is not in place, the equipment is prohibited from entering the subsequent clamping and detection stages, avoiding detection errors, equipment failures or product damage due to product placement deviations, and improving the safety and accuracy of the detection.

[0028] The probe holder 10 is evenly distributed with a number of probe terminals 22 and probes 23. The probe terminals 22 are used to connect the probes 23 to the detection module and the control module to ensure stable transmission of detection signals. The probes 23 are used to make precise contact with the detection points of the product 11 to realize the transmission of on / off signals and high voltage signals. The evenly distributed arrangement of a number of probes 23 can realize the simultaneous detection of multiple detection points of the product, improve detection efficiency, and at the same time ensure the comprehensiveness of detection coverage, avoiding the omission of detection points and the resulting product quality risks.

[0029] The chassis 1 has symmetrically fixed guide rails 24 for guiding the protective cover inside both sides. A protective cover 25 for enclosing the test area is slidably connected between the two sets of guide rails 24. The protective cover 25 is used to form a closed safety protection space during product testing to prevent operators from accidentally contacting high-voltage components, moving parts or the test area, thus preventing safety accidents. The chassis 1 has symmetrically fixed stroke cylinders 26 for driving the lifting and lowering of the protective cover inside and on both sides of the guide rails 24. The piston rod end of the stroke cylinder 26 is fixedly connected to the protective cover 25. The extension and retraction of the stroke cylinder 26 drives the protective cover 25 to rise and fall smoothly along the guide rails 24, realizing the automatic opening and closing of the test area without the need for manual operation by the operator, improving the convenience and safety of operation. The setting of the guide rails 24 can ensure the stability of the lifting and lowering process of the protective cover 25 and avoid deviation and jamming.

[0030] The surface of the chassis 1 is evenly distributed with two rows of test indicator lights 27 for feedback on the testing status. The test indicator lights 27 can display the equipment operating status, testing progress and testing results in real time, making it easy for operators to intuitively view the equipment's working status and quickly identify abnormal states. The surface of the chassis 1 is also integrated with a touch screen 28 and a high-voltage tester 29. The touch screen 28 serves as the core of the equipment's human-machine interaction, used to set test parameters, display test data, provide feedback on equipment status and input operating commands. It can preset test parameters for different product models, enabling quick parameter recall and reducing human operation errors. The high-voltage tester 29 is used to provide high-voltage signals for testing the high-voltage withstand performance of the product, accurately output the high-voltage parameters required for testing, and collect high-voltage test data in real time, providing a basis for judging the high-voltage performance of the product.

[0031] The top of the chassis 1 is fixedly equipped with a three-color alarm light 30 for feedback on abnormal equipment status. The three-color alarm light 30 can emit different colored light signals according to different working states of the equipment (normal operation, abnormal alarm, standby). It can also be combined with an audible alarm to facilitate operators to quickly identify the equipment status and handle abnormal situations in a timely manner. An emergency stop switch 31 is set at an easily accessible position at the front of the chassis 1. The emergency stop switch 31 is used to deal with emergencies during the testing process. Operators can press the emergency stop switch 31 at any time to immediately stop all actions of the equipment and quickly cut off the power and air supply, so as to maximize the personal safety of operators and the safety of the equipment and prevent the malfunction from escalating.

[0032] The bottom of the chassis 1 is equipped with several casters 32 at each of the four corners for moving the equipment. The casters 32 are made of wear-resistant and non-slip material, which can enable flexible movement and stable parking of the equipment. This facilitates the installation, debugging, maintenance and adjustment of the workshop layout without the need for external hoisting equipment, reducing the difficulty of equipment handling and improving the flexibility and convenience of equipment use. At the same time, the casters 32 can be locked to ensure that the equipment will not move accidentally during operation and to ensure the stability of the testing process.

[0033] Before starting this integrated high-voltage switching unit, power and compressed air connections must be completed. The power source module then begins operation: the power unit provides stable and continuous power to all electrical components, ensuring their normal operation; the compressed air unit provides sufficient power to all pneumatic components to meet their operational needs; and the air source treatment unit comprehensively processes the incoming compressed air, sequentially performing filtration, pressure reduction, and oil mist lubrication. This removes impurities from the compressed air, adjusts it to a suitable pressure to ensure cleanliness and stability, and lubricates and protects the pneumatic components, reducing the risk of air leakage. When components wear out, the equipment will automatically enter self-test mode after power is connected and power input is completed. Led by the PLC (Programmable Logic Controller), it will perform self-tests on each probe circuit, high-voltage tester, servo motor, all pneumatic components and safety protection components one by one to check for faults in each component and whether the test path is unobstructed, and to ensure that each component is operating normally. If an abnormality is found during the self-test, the three-color alarm light will issue an alarm prompt in time, and the touch screen will simultaneously display the abnormal location and related prompts. The equipment will immediately stop the start-up process. The operator needs to check and eliminate the fault and restart the self-test until the self-test is qualified before proceeding to the next operation. After passing the self-inspection, the operator begins the product placement and positioning clamping operation. The product 11 to be tested is placed stably on the special fixture of the fixed base 3. Depending on the product's shape (round or square), the corresponding auxiliary limit block is selected for initial positioning. An arc-shaped auxiliary limit block 4 is used for round products, and a square auxiliary limit block 5 is used for square products. This initially limits the product's placement position and avoids significant deviations. Subsequently, the copper positioning pin 20 on the fixed base 3 further positions the product 11, ensuring that the product's installation position fully meets the testing requirements, thus guaranteeing the accuracy of subsequent testing. Targeted detection sensors 21 are set at both ends of the fixed base 3 to detect whether round and square products are installed correctly. At the same time, the error-proof detection switch 12 simultaneously completes the product error-proof identification, mainly for products with the same shape but different specifications. By detecting the positional difference of the proximity sensor, it avoids putting unqualified products into testing. Once the sensor 21 detects that the product is installed in place and the error-proof detection switch 12 does not detect any error-proofing abnormalities, the PLC will issue a clear control command to trigger the three-jaw chuck 2 to firmly clamp one end of the product shaft through the fixed base 3, ensuring that the product 11 will not loosen or shift during the test. The magnetic switch 18 installed on the surface of the three-jaw chuck 2 will detect the clamping status in real time to determine whether the clamping is reliable and whether the clamping force required for the test is reached. If the clamping is not in place or is unreliable, the equipment will immediately issue an alarm prompt and prohibit entry into the subsequent test stage until the operator adjusts the product position and ensures that the clamping is reliable before continuing the operation. After the product 11 is clamped, the stroke cylinder 26 will push the protective cover 25 to descend smoothly along the guide rail 24, sealing the test area and forming an independent safety protection space, effectively preventing the operator from accidentally contacting high-voltage components or moving parts during the test and ensuring the personal safety of the operator. After the product 11 is clamped and protected and closed, the test parameter setting stage begins. The operator inputs the specific model of the product to be tested through the touch screen 28 on the surface of the chassis. The system will automatically retrieve the complete set of test parameters corresponding to the product 11 model according to the preset program, without the need for the operator to manually set them one by one. This saves operation time and avoids parameter setting errors. The operator needs to carefully check the retrieved test parameters and confirm that all parameters meet the test requirements of the product model before pressing the equipment start button. The equipment then officially enters the full-process test stage. To deal with emergencies during the test, the equipment is equipped with an emergency stop switch 31, which is installed at the front of the chassis 1. If the operator finds any abnormality during the test, he / she can press the emergency stop switch at any time, and the equipment will immediately stop all operations to ensure the safety of the equipment and personnel. After the equipment starts up, it first enters the high-voltage testing phase. The PLC sends a control command to the intermediate relay to control all probe 23 circuits to conduct, integrating them into a single unified circuit to ensure that the high-voltage test can fully cover the product's testing points. Subsequently, the high-voltage tester 29 starts to perform a high-voltage withstand performance test on product 11. During the test, the PLC collects relevant high-voltage test data in real time and compares it with the test range preset for this product model on the touch screen 28 to determine whether the product's high-voltage withstand performance is qualified. If the test data is found to exceed the preset qualified range, it means that the product's high-voltage withstand performance is unqualified, and the equipment will immediately stop, stopping all test operations. The three-color alarm light 30 emits a red alarm signal, and the touch screen 28 simultaneously displays the "NG" mark and related abnormal prompts to remind the operator that the product is unqualified and the cause of the abnormality. If the test data is within the preset qualified range, it means that the product's high-voltage test is qualified, and the touch screen will display the "OK" mark. The equipment will automatically switch to the next testing phase without manual intervention from the operator. After all high-voltage tests are completed, to ensure the accuracy of subsequent tests and avoid interference between different test stages, the equipment will automatically switch test modes. This switching process is controlled by the PLC to activate intermediate relays. If continuity tests or grounding resistance measurements are required later, the intermediate relays will disconnect all previously connected common circuits of probes 23 according to the PLC's instructions, disconnecting each probe 23 circuit separately. This ensures that each probe 23 forms its own independent closed-loop circuit, allowing subsequent tests such as continuity tests and grounding resistance measurements to be performed independently without interference. This guarantees the accuracy of each test and avoids deviations in test results due to circuit interference. After the mode switch is complete, the equipment enters the continuity test stage. The continuity test is divided into two exclusive modes depending on the product model: multimeter testing and ST-03 tester testing. The equipment will automatically identify and switch to the corresponding test mode based on the product model entered by the operator, without manual switching, adapting to the testing needs of different product specifications. Multimeter Test Mode: When the device switches to multimeter test mode, the PLC will issue a control command to control the intermediate relay to disconnect the test fixture from the high voltage tester 29 and the ST-03 tester, so as to avoid interference from other test equipment to the multimeter test. At the same time, it will sequentially connect or disconnect the circuit between the multimeter and each contact of the product to ensure that the multimeter can accurately detect the on / off status of each switch of the product. Before formal testing, the equipment will first perform a self-test of probe 23 contact, focusing on the contact between each probe 23 and the product 11 terminal to determine whether the probe 23 is in good contact, whether there is poor contact or no contact. The self-test results will be displayed on the touch screen 28 in real time for easy viewing by the operator. If a probe 23 is found to be in poor contact during the self-test, the system will clearly indicate the specific location of the probe 23 with poor contact and trigger the three-color alarm light 30 to issue a prompt. The operator can adjust the position of the probe 23 according to the prompt until all probes 23 are in good contact. After the probe 23 contact self-test is qualified, the PLC controls the servo motor 14 to start. The servo motor drives the fixed base 3 and the product shaft to rotate slowly through the coupling 17, so that the multimeter can detect the continuity of each switch of the product in turn, ensuring that each switch can be accurately detected. During the test, the continuity test results of each switch will be displayed on the touch screen 28 simultaneously. Switches that pass the test will display a green "OK" mark, and switches that fail the test will display a red "NG" mark. At the same time, the equipment will trigger an alarm prompt to remind the operator of the non-conformity. ST-03 Tester Test Mode: When the equipment switches to the ST-03 tester test mode, the PLC will control the intermediate relay to disconnect the test fixture from the high-voltage tester 29 and the multimeter, preventing other test equipment from interfering with the ST-03 tester's detection accuracy. Subsequently, the circuit between the ST-03 tester and each contact of the product will be sequentially connected or disconnected to prepare for testing. The probe 23 contact self-test process in this mode is the same as in the multimeter test mode. The equipment will re-check the contact between each probe 23 and the product terminal 11 to ensure good contact and avoid deviations in test results due to probe 23 contact problems. After the probe 23 contacts and passes the self-test, the servo motor 14 starts and drives the product shaft to rotate, enabling the ST-03 tester to sequentially complete the on / off test of each switch of the product. During the test, the ST-03 tester will use a dedicated sensor to detect the on / off state of the product indicator light 27 or the external signals emitted by the product, and transmit the collected signals to the PLC in real time. The PLC analyzes and processes the signals to determine whether the on / off state of the product switches is qualified. Finally, the test results of all switches are displayed on the touch screen 28 and the relevant test data is automatically saved for subsequent query and traceability. After the continuity test is completed, the equipment automatically enters the spline position detection stage. This stage mainly checks whether the spline installation angle of the product meets the design requirements to ensure the product assembly accuracy. During the test, with the flat position of the product shaft as the 0-degree reference, the PLC issues a control command to control the servo motor 14 to drive the product shaft and move the proximity switch slowly to the product switch position. Before the formal precision test, a continuity self-test is performed to confirm that the continuity between the proximity switch and the product switch is normal, avoiding inaccurate test results due to continuity problems. After the continuity self-test passes, a second precision test is performed, and relevant test data is recorded to ensure the reliability of the test results. The test process for the second switch is as follows. Similar to the first switch, the system synchronously records the rotation angles of both switches and compares the recorded angle data with the preset acceptable angle range for this product model on the touchscreen to determine whether the spline installation angle is acceptable. If the rotation angle is within the preset acceptable range, the touchscreen 28 displays a green "OK" indicator and simultaneously displays the currently detected angle value. If the rotation angle exceeds the preset acceptable range, it indicates that the spline installation angle is unacceptable, and the touchscreen 28 displays a red "NG" indicator. The three-color alarm light 30 issues an alarm prompt, and the touchscreen 28 displays the currently detected angle value, clearly indicating to the operator that the spline installation angle is unacceptable, facilitating subsequent adjustments. After the spline position detection is completed, the equipment enters the grounding resistance measurement stage. This stage mainly checks whether the product's grounding performance is qualified, ensuring the safety of the product during use. During measurement, the PLC sends a control command to control the movement of the cylinder. The piston rod of the cylinder moves the resistance detection contact point 13 (i.e., the ground wire connection point) slowly, ensuring it makes tight contact with the product's grounding screw. This ensures a firm contact and good conductivity, providing a stable measurement circuit for the grounding resistance measurement. Before the formal measurement, the equipment performs a continuity self-test to check the contact status between the resistance detection contact point and the product's grounding screw, and whether the measurement circuit is unobstructed, avoiding measurement failures due to poor contact or a broken circuit. If the measurement result deviates, and the self-test is passed, the equipment will activate the grounding resistance measurement function to measure the relevant grounding resistance data of the product in real time. The measurement data will be transmitted to the PLC in real time, where the PLC will process and analyze the data. The processed measurement result will then be displayed on the touch screen 28 and automatically saved to the equipment's storage module for later query, verification, and quality traceability. If the measurement result exceeds the preset acceptable range, it indicates that the product's grounding performance is unqualified, and the equipment will immediately issue an alarm, clearly marking the product as unqualified and reminding the operator to handle it. If the measurement result is within the acceptable range, the grounding resistance measurement is qualified, and the equipment will automatically proceed to the next stage. After the grounding resistance measurement is completed, all tests are finished. The PLC will summarize and judge the results of all tests to comprehensively evaluate whether the product is qualified. If all tests are qualified and there are no unqualified items, the PLC will issue a control command to control the push cylinder at the bottom of the fixed base 3 to move the piston rod of the cylinder to move the automatic stamp assembly 15 to print or stamp a qualified stamp at the designated position on the product valve body, thus completing the identification operation of qualified products, which is convenient for subsequent sorting and circulation. If any test is found to be unqualified after the summary judgment, the equipment will not perform the identification operation. At the same time, the touch screen 28 will clearly display all unqualified items and related abnormal prompts, and the three-color alarm light 30 will continuously emit alarm signals to remind the operator to deal with unqualified products in a timely manner. After the qualified marking operation is completed, the stroke cylinder 26 actuates, causing the protective cover 25 to rise smoothly along the guide rail 24, opening the safety protection space. Then, the three-jaw chuck 2 releases, releasing the clamp on the product. The operator can then remove the tested product from the fixed base 3. After the product is removed, the equipment automatically resets, and all components return to their initial state, awaiting the operator to place the next batch of products to be tested, entering a new round of testing. Test records for all batches of products can be exported or viewed in real-time via the touchscreen, facilitating quality control and data traceability during production. Throughout the entire testing process, the safety protection unit remains operational, comprehensively protecting the personal safety of operators and the safety of the equipment. The safety light curtain integrated in the safety protection unit scans the test area in real-time, detecting whether any operator's limbs have accidentally entered the danger zone. Once a limb is detected approaching or entering, a signal is immediately sent to the PLC. The PLC quickly issues control commands, immediately stopping the equipment, cutting off power and gas, and halting all operations to prevent accidents. Meanwhile, all doors to the control panel are equipped with access control systems that are linked to the equipment's operating status. If anyone opens a door during testing, the equipment will immediately trigger shutdown, power cut-off, and gas cut-off commands to prevent any potential danger. Furthermore, the equipment is equipped with dual emergency stop switches 31, which are always ready to be triggered during testing. Regardless of the operator's location, if an anomaly is detected, the emergency stop switch can be pressed quickly, immediately halting all components and cutting off power and gas supplies. This maximizes the safety of both the operator and the equipment, preventing further escalation of the malfunction.
