[0038] See Figure 1 As shown, the present application proposes a motor performance testing device 100. The motor performance testing device 100 includes a testing conveyor line 10, an abnormal sound tester 20, and a load tester 30. The testing conveyor line 10 is used to convey motors, and multiple test stations are set along one side of the testing conveyor line 10, each test station is used to arrange operator operations. The abnormal sound tester 20 is set corresponding to the test station upstream of the testing conveyor line 10 and is installed above the testing conveyor line 10. The load tester 30 is set corresponding to the test station downstream of the testing conveyor line 10 and is located on one side of the testing conveyor line 10.

[0039] In this application, the inspection conveyor line 10 is responsible for transporting the motors to be inspected from one end to the other, along a predetermined conveying path, ensuring that each motor passes through each test station in order. Each test station is equipped with corresponding testing equipment based on the test requirements, so that the operator can perform specific inspection operations.

[0040] Among them, the testing equipment includes an abnormal noise tester 20 and a load tester 30 for testing the motor. The abnormal noise tester 20 is used to detect whether the motor generates abnormal noise during operation. Abnormal noise may be caused by bearing damage, rotor imbalance or other mechanical failures. The abnormal noise tester 20 will start the motor and record its running sound. Then, by comparing with the preset noise standard or using the sound analysis algorithm, it is determined whether the motor has an abnormal noise problem. The load tester 30 is used to simulate the load conditions of the motor under actual working conditions to evaluate its key performance indicators such as output power, efficiency, stability and durability. By connecting the motor and applying a certain load, the operating parameters of the motor under different load conditions are observed and recorded to reflect the performance level of the motor.

[0041] The present invention integrates the motor noise tester 20 and the load tester 30 onto the same conveyor line. After the motor noise test is complete, the motor can be transported via the conveyor line to the load tester 30 for testing. By replacing manual transport with a conveyor line, the present invention improves the integration of the production line, enhances transport efficiency, reduces production costs, and improves product quality.

[0042] See Figure 1 As shown, in some embodiments, the test station includes a first station 11, a second station 12 and a third station 13 arranged along the extension direction of the detection conveyor line 10, the first station 11 is correspondingly provided with an abnormal sound testing machine 20, and the second station 12 and the third station 13 are correspondingly provided with a load testing machine 30.

[0043] In this embodiment, the number of tests of each type is rationally allocated based on the noise test time and the load test time. Relatively speaking, the load test takes longer, so more stations are used for motor load testing to ensure that more motors can be tested simultaneously, thereby improving the efficiency of motor performance testing.

[0044] See Figure 1 As shown, in some embodiments, there are two abnormal sound testing machines 20 , and the two abnormal sound testing machines 20 are respectively located on both sides of the first workstation 11 .

[0045] This allows two motors to be tested for abnormal noise simultaneously at the first workstation 11, completing more motor inspections in the same amount of time and significantly improving overall testing efficiency. Placing two abnormal noise testers 20 on either side of the first workstation 11 fully utilizes the workstation space and avoids interference between the devices. This layout also facilitates operator observation and operation during the test, improving work convenience and safety.

[0046] See Figure 1As shown, in some embodiments, the first workstation 11 is further provided with a corresponding load testing machine 30 .

[0047] It is worth noting that the premise for setting up the load testing machine 30 corresponding to the first workstation 11 is that the operator has spare time to operate the load testing machine 30 while operating the two abnormal sound testing machines 20 at the same time, thereby fully optimizing resource utilization.

[0048] Among them, the operator of the first workstation 11 can directly place the motor that has completed the abnormal sound detection on the load testing machine 30 for testing, which reduces the transportation time and waiting time of the motor at different workstations, improves the detection efficiency, and detects more motors faster.

[0049] See Figure 2 As shown, in some embodiments, the noise tester 20 includes a frame 21 and a soundproof box 22. The frame 21 is erected on the ground and has an escape passage 211 formed thereon for avoiding the inspection conveyor line 10. A mounting platform 212 is provided on the top of the frame 21. The soundproof box 22 is mounted on the mounting platform 212 and contains a decibel meter 221 for volume detection.

[0050] In this embodiment, the frame 21 is securely mounted on the ground, providing a stable support base for the entire testing machine and preventing testing errors caused by equipment shaking or instability. The avoidance passage 211 formed on the frame 21 allows the conveyor line to pass smoothly, allowing the frame 21 to be installed in the appropriate position. After the soundproof box 22 is installed on the mounting platform 212 of the frame 21, the soundproof box 22 can be positioned above the test conveyor line 10.

[0051] The soundproofing box 22 is a core component of the noise tester 20, used to isolate external noise interference and ensure test accuracy. A decibel meter 221 within the box accurately measures and records the noise level of the motor during operation. The measurement results from the decibel meter 221 can be used to determine whether the motor is experiencing noise issues, thereby ensuring that the motor's sound quality meets relevant standards and requirements.

[0052] See Figure 3 As shown, in some embodiments, a load testing machine 30 includes a test bench 31, a pressing member 32, and an oscilloscope 33. The test bench 31 is used to place and drive the motor to rotate and provide a braking load. The pressing member 32 is disposed above the test bench 31 and is pressed against the motor to maintain a stable state during motor rotation. The oscilloscope 33 is connected to the test bench 31 and is used to display and record real-time information about the motor's operating status.

[0053] In this embodiment, the main function of the test bench 31 is to place the motor and drive the motor to rotate through an internal mechanism. In addition to driving the motor to rotate, the test bench 31 can also provide a braking load. The braking load simulates the load conditions that the motor may encounter in actual applications, which helps to evaluate the working performance of the motor under different load conditions. The pressing member 32 is arranged above the test bench 31 and is used to be pressed above the motor when it rotates. The pressing member 32 is intended to maintain the stable state of the motor during rotation and prevent test errors caused by vibration or instability. The oscilloscope 33 is connected to the test bench 31 through an appropriate interface, and is used to display and record the working status information of the motor in real time, thereby providing detailed performance data.

[0054] Oscilloscope 33 can include a Hall effect waveform display and a dual-trace oscilloscope. Both these devices play an irreplaceable role in motor load testing. Together, they provide comprehensive data support and visual analysis tools for the testing process, helping engineers more accurately understand the motor's operating status and performance, thereby ensuring product quality and reliability.

[0055] See Figure 1 as well as Figure 4 As shown, in some embodiments, the motor performance testing equipment 100 also includes a material receiving and unloading device 40; the material receiving and unloading device 40 includes a unloading conveyor line 41 and a packaging conveying component 42; the unloading conveyor line 41 is arranged side by side with the testing conveyor line 10 and is located on the side of the testing conveyor line 10 away from the testing station, and is used to convey motors that have passed the performance test; the packaging conveying component 42 includes a packaging table 421 and a material frame conveying mechanism 422, the packaging table 421 is correspondingly arranged at the tail end of the unloading conveyor line 41, and is used to supply a motor packaging platform, and the material frame conveying mechanism 422 is arranged on one side of the packaging table 421, and is used to complete the unloading and conveying of the packaged material frame.

[0056] In this embodiment, the unloading conveyor line 41 is arranged side by side with the inspection conveyor line 10, and is located on the side of the inspection conveyor line 10 away from the testing station. This arrangement allows operators to smoothly transfer qualified motors from the inspection conveyor line 10 to the unloading conveyor line 41, while avoiding congestion and confusion caused by crossing or overlapping conveyor lines.

[0057] The packaging and conveying component 42 further includes a packaging table 421 and a material frame conveying mechanism 422. The packaging table 421 is correspondingly arranged at the tail end of the unloading conveying line 41, providing a stable platform for the packaging process of the motor. On the packaging table 421, staff can organize and pack the motors to ensure that the motors can be stored and transported safely and orderly. The material frame conveying mechanism 422 is arranged on one side of the packaging table 421, and its main function is to complete the unloading and conveying of the packaged material frame. After the motor is packaged, the material frame can be manually transferred to the material frame conveying mechanism 422 and transported to a designated storage area or transport vehicle. The automated unloading and conveying method not only improves work efficiency, but also reduces the labor intensity of manual handling.

[0058] See Figure 5 As shown, in some embodiments, a flexible blocking block 411 is provided at the tail end of the unloading conveyor line 41 . The flexible blocking block 411 is semi-frame-shaped with its opening facing the feed end of the unloading conveyor line 41 .

[0059] In this embodiment, the opening of the flexible blocking block 411 faces the feeding end of the unloading conveyor line 41, so that when the motor moves from the unloading conveyor line 41 to the flexible blocking block 411, the motor will enter the semi-frame-shaped opening and be effectively blocked, thereby preventing the motor from rushing out of the unloading conveyor line 41 and causing damage.

[0060] Furthermore, the blocking block is made of a flexible material, which can reduce impact force and vibration when blocking the motor, thereby protecting the motor.

[0061] See Figure 4 As shown, in some embodiments, the material frame conveying mechanism 422 is a roller conveying mechanism, and the roller conveying mechanism has a plurality of rollers arranged at intervals, and the plurality of rollers are driven to rotate by a motor.

[0062] The roller conveyor mechanism can quickly and stably transport the material frame, improving the overall efficiency of the production line. In the motor performance testing equipment, the roller conveyor mechanism serves as the material frame conveyor mechanism 422, which can quickly and accurately transport qualified motors to the docking area for subsequent processing, thereby improving the overall efficiency and automation level of the production line.

[0063] See Figure 4 As shown, in some embodiments, the material receiving and unloading device 40 also includes a code scanning component 423 arranged at the tail end of the unloading conveyor line 41 adjacent to the packaging table 421; the code scanning component 423 includes a code scanning table 424 and a code scanner 425; the code scanning table 424 is used to place the motor; the code scanner 425 is correspondingly arranged above the code scanning table 424, and is used to scan the motor on the code scanning table 424.

[0064] In this embodiment, by further setting up a code scanning component 423, key information such as the production information, test data, and packaging time of each motor can be recorded. This facilitates product traceability, quality management, and after-sales service. A code scanning process is:

[0065] Motors that have passed performance testing are transported from the unloading conveyor line 41 and manually placed on a barcode scanning station 424. A barcode scanner 425 then automatically scans the motors on the station. The scanner captures the QR code or barcode image on the motors and decodes it using an internal algorithm, extracting the information. The decoded information is then transmitted to the production line's control system or database. This information is used for motor tracking, management, and statistical analysis.

[0066] The above description is only a partial or preferred embodiment of the present application. Neither the text nor the drawings can limit the scope of protection of the present application. Any equivalent structural transformation made by using the contents of the present application specification and drawings under the overall concept of the present application, or direct / indirect application in other related technical fields, is included in the scope of protection of the present application.
