Description

Technical Field

[0001] This invention relates to the field of sweeper testing technology, and more specifically to an automated testing device for sweepers. Background Technology

[0002] A robotic vacuum cleaner typically includes multiple functional modules such as drive wheels, roller brush, mop assembly, downward-facing sensor, edge sensor, charging assembly, and voice control. After the robotic vacuum cleaner is manufactured and assembled, these functional modules usually need to be functionally tested and calibrated to determine whether the entire machine meets the factory requirements.

[0003] In existing robotic vacuum cleaner testing processes, some test items still rely on manual operation. However, manual operation is prone to errors in test results due to improper operation.

[0004] For example, color and distance calibration of downward-facing sensors typically requires testing with calibration components of different colors or heights. If testing is conducted manually or by changing calibration components, inconsistencies in placement position, height, or testing sequence can easily affect the consistency of test results. Similarly, drive wheel drop tests usually require simulating the triggering state of the drive wheel after an impact or drop. If testing is conducted manually with different fixtures, inconsistencies in the magnitude of the force, the stroke, and the position of impact can easily occur, leading to poor repeatability of the test results. Summary of the Invention

Detailed Implementation

[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0026] In this application, unless otherwise stated, directional terms such as "up," "down," "vertical," and "horizontal" are generally used based on the orientation of the automated testing equipment during normal placement and use; "below" refers to the direction towards the bottom of the main body of the machine, and "above" refers to the direction towards the top of the main body of the machine. "Connection" can be a direct connection or an indirect connection through an intermediate structure; "set to" can be a fixed setting or a detachable setting, as long as the installation, support, or mating relationship between the corresponding structures can be achieved.

[0027] As mentioned earlier, sweepers need to be tested to ensure all functions are working properly before leaving the factory. Currently, many tests require manual operation and need to be conducted at multiple workstations. This can lead to errors in test results due to improper operation by the testers, and the need to move the sweeper to multiple workstations for testing results in low efficiency.

[0028] Therefore, this invention proposes an automated testing device for sweeping machines. The following is a description of the device in conjunction with the appendix. Figures 1-4 This invention provides a detailed description of an automated testing device for a sweeping machine.

[0029] like Figure 1As shown, the present invention provides an automated testing device 100 for a sweeping machine. (As indicated...) Figures 1-4 As shown, the automated testing equipment 100 includes a machine body 1, a rotating platform 2, a first driving component 4, a functional testing mechanism, and an industrial control computer 7. The functional testing mechanism includes a downward calibration component 5 and / or a drop test component 6.

[0030] Optionally, the functional test mechanism may include only the downward calibration component 5, or only the drop test component 6. Of course, the functional test mechanism may also be an integrated mechanism of both the downward calibration component 5 and the drop test component 6.

[0031] Specifically, the main body 1 of the test platform serves as the basic load-bearing structure of the automated testing equipment 100, and can be used to install and support structures such as the rotating platform 2, the first drive component 4, the downward calibration component 5, the drop test component 6, and the industrial control computer 7. The main body 1 of the test platform can be a box, a frame, a platform, or a support structure formed by a combination of profiles and plates, as long as it can provide a stable mounting foundation for each testing component.

[0032] like Figures 2-3 As shown, the drive wheel detection of the sweeper is used to test whether the sweeper can identify a stable supporting plane when it is supported by a plane, and whether it can detect the drive wheel being suspended when it is not supported and is suspended, thus requiring the sweeper to stop moving.

[0033] Therefore, when the drop test component 6 impacts the drive wheel, it simulates the impact of the sweeper falling from a certain height. When the drop test component 6 disengages from the drive wheel and the drive wheel is suspended in the air, the sweeper can detect the current suspended state and needs to stop moving to prevent the sweeper from falling from this point.

[0034] like Figure 4 As shown, the opening 21 allows the drop test component 6, located below or to the side of the rotating platform 2, to act on the drive wheel of the sweeper through the opening 21, thereby completing the drive wheel drop test while the sweeper remains clamped and positioned. The rotating platform 2 can be configured as a disc-shaped, plate-shaped, or a support structure adapted to the shape of the bottom of the sweeper.

[0035] like Figure 3 As shown, the first driving component 4 is mounted on the main body 1 of the machine. The first driving component 4 can drive the rotating platform 2 to rotate around a rotation axis perpendicular to the horizontal plane, and can also stop the rotating platform 2 at a preset position. By driving the rotating platform 2 to rotate via the first driving component 4, the sweeper can switch test angles or test positions relative to the downward calibration component 5, the drop test component 6, and other test components in the same clamping state. Therefore, there is no need to transport the sweeper to multiple testing stations; multiple functions can be tested with a single clamping. The test results have small errors and high testing efficiency.

[0036] like Figure 3 As shown, the downward calibration component 5 is set on the main body of the machine tool 1 and includes multiple test color cards 51 with a height lower than the rotating stage 2.

[0037] Optionally, the multiple test color cards 51 can be black and white color cards. The multiple test color cards 51 can also include black, white, and gray color cards. Furthermore, test color cards of more colors can be set as needed. The first driving component 4 drives the rotating platform 2 and the sweeping machine to rotate, causing the sweeping machine's downward-facing sensor to sequentially pass through different test color cards 51, thereby completing the downward-facing calibration function test of the sweeping machine.

[0038] The multiple test color cards 51 can be at different heights, and the height of the multiple test color cards 51 is lower than that of the rotating platform 2. Thus, the multiple test color cards 51 can have different colors and different heights, so that the downward-facing sensor of the sweeping machine can complete the color calibration and distance calibration in the same device.

[0039] like Figures 2-4 As shown, the drop test assembly 6 is located below or to the side of the rotating platform 2 to perform drop tests on the drive wheels of the sweeper. The drop test assembly 6 can apply force to the drive wheels of the sweeper through the opening 21 or from the side of the rotating platform 2 to simulate the trigger state of the drive wheels when subjected to a drop impact.

[0040] The industrial control computer 7 is electrically connected to the first drive component 4 and the functional testing mechanism. The industrial control computer 7 can run testing software and control the actions of the first drive component 4, the downward calibration component 5, and the drop test component 6 according to a preset testing procedure, while simultaneously collecting relevant test data. The entire testing process is convenient and fast, with stable data transmission, small errors, and high efficiency.

[0041] According to an automated testing device 100 of the present invention, through the cooperation of the machine body 1, rotating platform 2, first drive component 4, downward calibration component 5, drop test component 6, and industrial control computer 7, a sweeping machine can complete rotational positioning, downward calibration, and drive wheel drop test under the same clamping and pressing state. This reduces the transfer and repetitive positioning between different testing stations, minimizes inconsistencies caused by manual placement of color cards, manual adjustment of positions, or manual impact on the drive wheels, and improves testing efficiency, repeatability, and reliability.

[0042] In some embodiments of the present invention, such as Figure 1 , Figure 3 and Figure 4 As shown, the rotating platform 2 is rotatably mounted on the machine body 1 to support the sweeper. The platform of the rotating platform 2 has an opening 21 corresponding to the drive wheel of the sweeper.

[0043] like Figure 4 As shown, the opening 21 allows the drop test component 6, located below or to the side of the rotating platform 2, to act on the drive wheel of the sweeper through the opening 21, thereby completing the drive wheel drop test while the sweeper remains clamped and positioned. The rotating platform 2 can be configured as a disc-shaped, plate-shaped, or a support structure adapted to the shape of the bottom of the sweeper.

[0044] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the automated testing equipment 100 also includes a limiting component 3, which is disposed on the rotating platform 2. After the sweeper is placed on the rotating platform 2, the limiting component 3 can position the sweeper on the rotating platform 2, making it less likely for the sweeper to shift relative to the rotating platform 2 during rotation, downward calibration, and drop testing. In one embodiment, the limiting component 3 can press and position the sweeper on the rotating platform 2, ensuring that the sweeper maintains a fixed relative position with the rotating platform during rotation and during the execution of testing actions by various testing components. This prevents displacement of the sweeper due to vibration or centrifugal force during testing, thereby ensuring the alignment accuracy between the downward sensor and the test color card, the positional accuracy between the drop test component and the drive wheel, and the test positional accuracy of other testing components. Furthermore, the pressing and positioning method can adapt to sweepers with different bottom structures or different models, eliminating the need for separate slots or contour positioning structures for each model, thus improving the equipment's versatility and compatibility.

[0045] In some embodiments of the present invention, such as Figures 3-4 As shown, the limiting component 3 includes a fixed end 31 and a limiting end 32. The fixed end 31 is disposed on the rotating platform 2, and the limiting end 32 is rotatably disposed on the fixed end 31. The fixed end 31 can serve as the mounting base for the limiting end 32, and the limiting end 32 can rotate relative to the fixed end 31 to switch between a released state and a clamping state. When clamping the sweeper is required, the sweeper is first placed on the rotating platform 2, and then the limiting end 32 is rotated to a position above the sweeper to clamp it. When the clamping function is not required, the limiting end 32 can be rotated to a position that does not obstruct the space above the rotating platform 2, thereby facilitating the placement or removal of the sweeper from the rotating platform 2 without interference from the limiting component 3.

[0046] In some embodiments of the present invention, such as Figure 4As shown, the automated testing equipment 100 also includes multiple positioning posts 22. All positioning posts 22 are disposed on the upper surface of the rotating platform 2. The multiple positioning posts 22 can cooperate with positioning holes, positioning grooves, edge structures, or other positioning parts on the bottom of the sweeper to confine the sweeper to the rotating platform 2. The positioning posts 22 can perform initial positioning of the sweeper during placement, keeping the sweeper fixed relative to the rotating platform 2.

[0047] Therefore, with the positioning column 22 and the limiting component 3 working together, the sweeper is less likely to deviate when rotating with the rotating platform 2, performing downward calibration and drop test, thereby improving the positional consistency between the sweeper and each test component and reducing test errors caused by loose clamping or positional deviation.

[0048] In some embodiments of the present invention, such as Figure 3 As shown, the first driving component 4 includes a servo motor. The output shaft of the servo motor is connected to the rotary platform 2 to drive the rotary platform 2 to rotate relative to the machine body 1. The servo motor can be directly connected to the rotary platform 2, or it can be connected to the rotary platform 2 through a transmission structure such as a reducer, coupling, synchronous belt, gear set, or hollow rotary platform.

[0049] Specifically, the industrial control computer 7 can send control commands to the servo motor, causing the servo motor to drive the rotating platform 2 to rotate to the corresponding test position. When the rotating platform 2 rotates, the sweeper mounted on the rotating platform 2 rotates synchronously, so that the sweeper's downward-looking sensor, edge sensor, IR communication component, or other parts under test can be sequentially matched with the corresponding test components.

[0050] Therefore, the servo motor, with its superior angle and speed control capabilities, improves the control accuracy of the rotating platform 2's rotation and stopping positions. Driving the rotating platform 2 with the servo motor allows the sweeper to rotate stably to the corresponding test position, facilitating the sequential passing of the downward-looking sensors through the test color chart 51. This also facilitates subsequent expansion into gyroscope dynamic testing, IR omnidirectional communication testing, or other tests requiring rotation, thereby improving the equipment's testing accuracy and expandability.

[0051] In some embodiments of the present invention, such as Figure 2 and Figure 4 As shown, the downward calibration component 5 also includes multiple lifting components 52. All lifting components 52 are mounted on the main body 1 of the machine, and their lifting ends are connected to corresponding test color cards 51. The lifting components 52 can be cylinders, electric push rods, lead screw lifting mechanisms, linear modules, or other structures capable of lifting the test color cards 51.

[0052] Specifically, multiple test color cards 51 can be installed on the lifting ends of corresponding lifting components 52. When the lifting components 52 are activated, they can move the corresponding test color cards 51 up or down in the vertical direction to adjust the distance between the test color cards 51 and the robot vacuum's downward-facing sensor. Different test color cards 51 can be set to different colors, such as black, white, gray, or other colors used for downward-facing recognition. Different test color cards 51 can also be positioned at different heights by the lifting components 52 for distance calibration by the robot vacuum's downward-facing sensor.

[0053] During the test, the industrial control computer 7 can control the first drive component 4 to drive the rotating platform 2 to rotate, so that the sweeper's downward-facing sensor passes through different test color cards 51 in sequence. At the same time, the industrial control computer 7 can control the lifting component 52 to adjust the height of the test color cards 51, so that the test color cards 51 are at different heights.

[0054] Therefore, the sweeper can complete downward calibration under different colors and height conditions in the same clamping state. Compared with manual placement or replacement of calibration parts, the lifting component 52 can improve the repeatability of the position and height of the test color card 51, reduce human operation errors, and make the downward calibration process more standardized and automated.

[0055] In some embodiments of the present invention, such as Figure 3 As shown, the drop test assembly 6 includes a second drive component 61 and a test end 62. The second drive component 61 is mounted to the main body 1 of the machine, and the test end 62 is connected to the power end of the second drive component 61. The second drive component 61 can be a cylinder, an electric push rod, a linear motor, or other drive structure capable of outputting linear motion. The test end 62 can be a push block, an impact head, a top block, a contact head, or other structure capable of acting on the drive wheel of the sweeper.

[0056] Specifically, the test end 62 can be positioned corresponding to the opening 21 of the rotating platform 2, or it can be located on the side of the rotating platform 2. During testing, the second drive unit 61 drives the test end 62 to move towards the drive wheel of the sweeper, simulating the trigger state when the drive wheel is subjected to a drop impact by colliding with the drive wheel. The industrial control computer 7 can control the timing of the action of the second drive unit 61 and read the feedback signal from the sweeper regarding the trigger state of the drive wheel.

[0057] Therefore, by driving the test end 62 through the second drive component 61 to act on the drive wheel of the sweeper, a drop test can be conducted with a relatively stable stroke, position, and force. Compared with manual operation through impact or manual lifting, this ensures that the drop test conditions of the drive wheel are the same, making the test results more reliable and reducing errors.

[0058] In some embodiments of the present invention, such as Figure 2 and Figure 3As shown, the automated testing equipment 100 also includes a cloth position testing component 8. The cloth position testing component 8 is mounted on the main body 1 of the machine. It includes a third driving component 81 and a magnetic component 82. The magnetic component 82 is mounted on the power end of the third driving component 81, so that it moves towards the cloth Hall sensor of the sweeping machine under the drive of the third driving component 81. The third driving component 81 can be a cylinder, an electric push rod, a linear module, or other similar structure. The magnetic component 82 can be a permanent magnet or other magnetic component that can trigger the cloth Hall sensor of the sweeping machine.

[0059] Specifically, the third driving component 81 drives the magnetic suction component 82 to approach the mop Hall sensor on the sweeper, causing the sweeper to recognize the mop as installed. The third driving component 81 also drives the magnetic suction component 82 away from the mop Hall sensor, causing the sweeper to recognize the mop as removed. The industrial control computer 7 can read the mop presence signal output by the sweeper or the feedback signal from the mop Hall sensor to determine whether the sweeper's mop presence detection function is working properly.

[0060] In some embodiments of the present invention, the industrial control computer 7 can also record the magnetic field strength or Gaussian value of the magnetic suction component 82, and save the recorded data in correspondence with the output signal of the cloth Hall sensor. Thus, the cloth position testing component 8 can automatically simulate the cloth installation and removal states without requiring repeated manual disassembly and reassembly of the cloth. Driving the magnetic suction component 82 with the third driving component 81 can improve the testing efficiency of the cloth position test.

[0061] In some embodiments of the present invention, such as Figure 3 As shown, the automated testing equipment 100 also includes an edge calibration component 9. The edge calibration component 9 is mounted on the main body 1 of the machine tool, and the edge calibration component 9 can be raised and lowered in the vertical direction.

[0062] Specifically, the edge calibration component 9 may include a black and white card, a calibration plate, or other calibration components that can be recognized by the edge sensor of the sweeping machine. When the edge calibration component 9 is raised or lowered, the calibration component can enter or exit the detection area of ​​the edge sensor of the sweeping machine to complete the edge color calibration or edge distance calibration.

[0063] In some embodiments of the present invention, such as Figure 2 As shown, the automated testing equipment 100 also includes an edge testing component 10, which is disposed on the main body 1 of the machine. The edge testing component 10 includes a fourth drive member 101, the telescopic end of which can extend with a predetermined stroke and impact the sweeper with a predetermined force.

[0064] In some embodiments of the present invention, the telescopic end of the fourth driving member 101 may be provided with a contact 102, which corresponds to the edge sensor area of ​​the sweeping machine. The fourth driving member 101 may be a cylinder, an electric push rod, a linear module, or other structures.

[0065] Specifically, the edge calibration component 9 can raise and lower the calibration element to a predetermined calibration position, allowing the edge sensor of the sweeper to be calibrated. The edge testing component 10 can drive the contact 102 to impact the edge sensor area of ​​the sweeper with a predetermined stroke and force via the fourth drive component 101. The industrial control computer 7 can collect the edge collision switch signal or the edge sensor trigger signal of the sweeper to determine whether the edge-related functions are normal.

[0066] Therefore, the edge calibration component 9 can provide stable calibration conditions for the edge sensors of the sweeper, and the edge testing component 10 can perform impact tests on the sweeper with a predetermined stroke and predetermined force. When the two work together, the automated testing equipment 100 can complete both edge color or distance calibration and edge triggering tests, improving the reliability of edge function test results and reducing errors.

[0067] In some embodiments of the present invention, such as Figure 3 As shown, the automated testing equipment 100 also includes a downward-looking testing component 11.

[0068] Specifically, the downward-facing testing component 11 is installed on the main body 1 of the robot vacuum. The downward-facing testing component 11 includes a floor module and a carpet module. The floor module can be used to simulate the robot vacuum's operation on hard surfaces in a home environment, and the carpet module can be used to simulate the robot vacuum's operation on carpets in a home environment. During the test, the robot vacuum can identify the floor module and carpet module through the downward-facing sensor or related detection module, thereby determining whether its floor type recognition function is normal.

[0069] Furthermore, the downward-looking testing component 11 can be an ultrasonic downward-looking testing component.

[0070] In some embodiments of the present invention, such as Figure 3 and Figure 4 As shown, the automated testing equipment 100 also includes a rechargeable auxiliary testing component 12. The rechargeable auxiliary testing component 12 is mounted on the rotating platform 2. The rechargeable auxiliary testing component 12 includes a charging connector that can be electrically connected to the charging port of the sweeper. After the sweeper is placed and firmly positioned on the rotating platform 2, the charging connector can mate with the sweeper's charging port to test the sweeper's charging function. Simultaneously, the industrial control computer 7 can collect data such as the sweeper's charging status, charging voltage, and charging current to determine whether the sweeper's rechargeable function meets the requirements.

[0071] In some embodiments of the present invention, the automated testing equipment 100 further includes a parameter measurement module. The parameter measurement module is integrated into the data acquisition card or dedicated measurement board of the industrial control computer 7. The parameter measurement module can be connected to the sweeper via test harnesses, terminals, communication interfaces, or other acquisition interfaces to collect the electrical parameters of the sweeper during the testing process.

[0072] The parameter measurement module can be used to measure the current and voltage of at least one of the following motors in the sweeper: LDS motor, drive wheel motor, roller brush motor, and mop motor. It can also measure at least one of the following parameters: battery voltage, charging voltage, charging current, WiFi signal strength, and WiFi signal frequency. The industrial computer 7 can use the data collected by the parameter measurement module to determine if there are any abnormalities in the sweeper's motor, battery, charging, or wireless communication.

[0073] In some embodiments of the present invention, the automated testing equipment 100 further includes a wireless communication board.

[0074] Specifically, a wireless communication board is installed on the main body 1 of the machine to connect to and bind with the sweeper via terminals for transmitting test commands, reading status data, and burning firmware. The wireless communication board is also connected to the industrial control computer 7. Thus, the industrial control computer 7 can interact with the sweeper via the wireless communication board.

[0075] In some embodiments of the present invention, the automated testing equipment 100 further includes a communication test board. The communication test board is mounted on the main body 1 of the testing platform to simulate the signal transmission and reception functions of a base station for the sweeper, enabling signal communication testing with the sweeper. The communication test board is connected to the industrial control computer 7. It is understood that the communication test board can send infrared signals to the sweeper and receive infrared signals emitted by the sweeper to verify the sweeper's signal communication function. When the rotating platform 2 rotates, the IR communication status of the sweeper can also be tested at different angles.

[0076] Optionally, the communication test board can be a 5G wireless communication board or an IR communication test board. The IR communication test board can simulate the infrared signal transmission and reception function of the robot vacuum cleaner's base station to conduct infrared signal communication tests with the robot vacuum cleaner.

[0077] In some embodiments of the present invention, the automated testing device 100 further includes a voice testing component 15, such as... Figure 4As shown, the voice testing component 15 is mounted on the rotating platform 2. The voice testing component 15 is used to collect audio data played by the sweeper and is connected to the industrial control computer 7. The voice testing component 15 may include a microphone or other sound acquisition devices. After the sweeper plays a preset audio, the voice testing component 15 collects the audio data and transmits it to the industrial control computer 7. The industrial control computer 7 can determine whether the sweeper's voice playback function is normal based on the audio data.

[0078] In other words, during the test, the robot vacuum plays audio, and the microphone of the voice test component 15 records the audio. The industrial control computer 7 then analyzes the audio's spectrum, total harmonic distortion (THD), signal-to-noise ratio (SNR), and other indicators to determine whether the robot vacuum's speaker has any distortion, noise, or other defects.

[0079] The wireless communication board, communication test board, and voice test component are all connected to the industrial control computer.

[0080] Therefore, the industrial control computer 7 can use testing software to summarize, judge, and store the status data read by the wireless communication board, the IR communication test data generated by the communication test board, the audio data collected by the voice test component 15, and other test data. In some embodiments, the industrial control computer 7 can also bind the test data with product identification information and upload it to the production management system for quality traceability. Furthermore, manual recording is eliminated, reducing the error rate.

[0081] The present invention is not limited thereto. The automated testing equipment 100 of the present invention may also be equipped with an LDS lifting detection component, thereby further detecting the LDS lifting function of the sweeper.

[0082] This integrates dozens of testing functions, including LDS, electrical, communication, mechanical, optical, acoustic, and magnetic testing, into a single machine, achieving the effect of "one-time setup, all-item testing." It solves the problems of fragmented testing and inefficient workflow in existing technologies.

[0083] In some embodiments of the present invention, such as Figure 1 As shown, the automated testing equipment 100 may also include a human-machine interface device 16. The human-machine interface device 16 can be a display screen. It can then be connected to the industrial control computer 7 to display test status, test results, and alarm information.

[0084] In summary, current robotic vacuum cleaner testing processes require testers to manually turn on the vacuum cleaner and observe its operating status, such as whether it moves and whether the side brushes rotate. Dedicated debugging software is then connected to read certain parameters, such as software version and battery level. Multimeters and other tools are also needed to test specific electrical parameters, such as charging voltage and current. Furthermore, the functionality of sensors, such as edge detection, drop detection, and gyroscope verification, is typically done by testers manually triggering or changing the vacuum cleaner's posture, such as lifting or tilting, to make a rough assessment.

[0085] If testing is conducted via artificial impact or with different tooling, inconsistencies in the magnitude of the force, the stroke, and the position of impact can easily arise, leading to poor repeatability of the test results. This results in the following problems: 1. Low test coverage and quality blind spots: Manual testing is limited by the testers' time. For example, it is impossible to accurately measure dynamic parameters such as real-time changes in drive wheel current and roller brush current, and it is also impossible to simulate complex home environment conditions, such as simultaneous rotation, impact, and communication interference of the robot vacuum. Core performance such as gyroscope accuracy, voice distortion, and IR communication error rate cannot be effectively tested manually, resulting in defective products being released.

[0086] 2. Poor test consistency and repeatability: Subjective differences exist in the operating methods and judgment standards of different testers. For example, in judging whether "edge impact triggers," some people stop with a light touch while others hit hard, leading to unreliable test results. This is due to the lack of standardized mechanical triggering and quantitative evaluation methods.

[0087] 3. Low testing efficiency and high labor costs: Manually testing dozens of functions one by one is extremely time-consuming per unit and prone to errors due to fatigue. To meet production capacity, a large number of testing personnel are required, resulting in high labor costs.

[0088] 4. Lack of data traceability: Manual test results are usually recorded in paper reports or Excel spreadsheets, which cannot be automatically and in real time linked to the product's unique serial number and uploaded to the Manufacturing Execution System (MES). When quality problems occur, it is difficult to quickly trace the specific test data and the product's status at the time, which is detrimental to quality analysis and process improvement.

[0089] 5. Some functions cannot be simulated: For example, "downward calibration" requires ground of different heights and colors, "mop Hall sensor" detection requires precise control of magnet distance, and "drop test" requires impact of specific force and speed. These cannot be completed stably and accurately by humans.

[0090] 6. Root cause analysis of defects: The functions of the sweeping robot are highly integrated, and the test items are numerous and involve a variety of physical quantities, such as electrical, optical, acoustic, magnetic and mechanical. The existing technology has not integrated all the test items into one, realizing a fully automatic, standardized and quantifiable comprehensive test platform.

[0091] The overall working principle and technical effects of the present invention will be described in detail below with reference to the above-described technical solutions.

[0092] like Figures 1 to 4As shown, when using the automated testing equipment 100, the sweeper can first be placed on the rotating platform 2 by a robotic arm. The robotic arm can be an independent robotic arm device, and its position can be arranged according to actual needs. The robotic arm realizes the automatic loading and unloading process, that is, automatic placement and automatic removal of the sweeper. After the sweeper is placed in place, the positioning column 22 limits the sweeper. The limiting end 32 of the limiting component 3 rotates relative to the fixed end 31 and presses the sweeper, so that the sweeper is stably positioned on the rotating platform 2. Subsequently, the industrial control computer 7 starts the testing process and controls the first driving component 4 to drive the rotating platform 2 to rotate.

[0093] The specific testing process is as follows: During the actual test, the robotic arm places the sweeper on the rotating platform 2, the positioning column 22 positions the sweeper, and the limiting component 3 presses the sweeper firmly onto the rotating platform 2. The 5G wireless communication board establishes communication with the sweeper, and the industrial control computer 7 reads the sweeper's software version, burns the firmware, and reads the voice version. The parameter measurement module measures the sweeper's static power and voltage. The industrial control computer 7 controls the first drive component 4 to start, causing the rotating platform 2 to rotate the sweeper for gyroscope testing, downward calibration of the downward calibration component 5, and IR omnidirectional communication testing of the IR communication test board. Subsequently, the industrial control computer 7 sequentially controls the drop test component 6, the edge test component 10, and the mop position test component 8 to perform drive wheel drop tests, edge tests, and mop position tests, respectively. During the test, the parameter measurement module collects the current, voltage, and WiFi signal of each motor of the sweeper in real time, and the voice test component 15 collects the audio data played by the sweeper and analyzes it by the industrial control computer 7. The industrial computer 7 uploads all test data to the MES system. After the test is completed, the limit component 3 releases the sweeper, and the robotic arm removes the sweeper from the rotating platform 2.

[0094] Specifically, during the downward-view calibration process, the industrial control computer 7 controls the first drive component 4 to rotate the rotating platform 2, causing the sweeper's downward-view sensor to sequentially pass through multiple test color cards 51 in the downward-view calibration assembly 5. These multiple test color cards 51 can have different colors and different heights, and the lifting component 52 can further adjust the height of the corresponding test color cards 51. Thus, the sweeper can complete the color calibration and distance calibration of the downward-view sensor in the same clamping state.

[0095] During the drive wheel drop test, the industrial control computer 7 controls the action of the drop test component 6. The second drive component 61 drives the test end 62 to act on the drive wheel of the sweeper to simulate the trigger state when the drive wheel is subjected to a drop impact. The industrial control computer 7 collects the corresponding test data to determine whether the drive wheel drop-related functions are normal.

[0096] During the mop position test, the third drive component 81 drives the magnetic suction component 82 to approach or move away from the mop Hall sensor on the robot vacuum to simulate the mop installation and removal states. During the edge-keeping test, the edge-keeping calibration component 9 provides edge-keeping calibration conditions through lifting and lowering movements, and the edge-keeping test component 10 drives the contact 102 to impact the robot vacuum with a predetermined stroke and predetermined force through the fourth drive component 101 to detect edge-keeping related functions. During the ground scene and recharging test, the downward-looking auxiliary test component 11 simulates different ground scenes through the floor module and carpet module, and the recharging auxiliary test component 12 connects to the charging port of the robot vacuum through the charging connector to detect the recharging function.

[0097] In addition, the parameter measurement module can collect parameters related to the robot vacuum's motor, battery, charging, and WiFi during the test. The 5G wireless communication board can transmit test commands, read status data, and burn firmware. The IR communication test board can perform IR communication tests with the robot vacuum. The voice test component 15 can collect audio data played by the robot vacuum. All the above test data can be transmitted to the industrial control computer 7, where the test software running on the industrial control computer 7 records the data. The human-machine interface device 16 can be connected to the industrial control computer 7 to display test status, test results, and alarm information.

[0098] In summary, the automated testing equipment 100 of the present invention, through the cooperation of the rotating platform 2, the limiting component 3, the first driving component 4, the downward calibration component 5, the drop test component 6, and the industrial control computer 7, realizes the rotational positioning, downward calibration, and drive wheel drop test of the sweeper in the same clamping state. Furthermore, the number of test items for the entire machine is further increased through the mop position test component 8, the edge calibration component 9, the edge test component 10, the downward auxiliary test component 11, the rear recharge auxiliary test component 12, the parameter measurement module, the 5G wireless communication board, the IR communication auxiliary test board, and the voice test component 15. This reduces manual intervention and repetitive clamping, improving the efficiency, consistency, reliability, and test coverage of the sweeper's functional testing.

[0099] The preferred embodiments of this application have been described in detail above with reference to the accompanying drawings; however, this application is not limited thereto. Within the scope of the technical concept of this application, the various specific technical features in the above embodiments can be appropriately combined, replaced, or adjusted. For example, the first driving component 4 is not limited to a servo motor, but can also be other driving structures capable of driving the rotating platform 2 to rotate. The second driving component 61, the third driving component 81, and the fourth driving component 101 are not limited to cylinders, but can also be electric push rods, linear motors, or other linear drive structures. The number, color, and height of the test color cards 51 can be adjusted according to the sweeper model and testing requirements. The installation position of each test component on the machine body 1 or the rotating platform 2 can be adaptively adjusted according to the structural dimensions of the sweeper. To avoid unnecessary repetition, this invention will not describe various possible combinations separately. However, these simple variations and combinations should also be considered as the content disclosed in this invention and are all within the protection scope of this invention.
