Description

Technical Field

[0001] The present invention relates to the technical field of hair dryer testing equipment, and particularly relates to an integrated hair dryer aging testing machine. Background Art

[0002] As a commonly used household appliance, the safety, performance stability, and functional integrity of a hair dryer are directly related to the user experience and safety. Therefore, strict functional tests and aging verifications are required during the production process. With the continuous improvement of market requirements for product quality, many problems have gradually emerged in the traditional hair dryer testing methods.

[0003] In the prior art, the functional tests and aging tests of hair dryers are mostly carried out using decentralized equipment. Multiple functional tests require manual operations, which not only have low test efficiency, but also are prone to data errors due to fatigue or inconsistent operations, affecting the reliability of test results. At the same time, aging tests usually require a separate offline aging room to be set up. After the functional tests are completed, the hair dryers are manually transported to the aging room for long-term operation verification. This process not only occupies a large amount of factory space, but also causes the interruption of the test process due to the transportation link, making it difficult to achieve coherent analysis of functional parameters and aging data. Summary of the Invention

Multiple temperature sensors are evenly distributed in the support base, which can monitor the temperature distribution of the hair dryer in the low-speed cold air mode. The ion testing mechanism includes an ion tester and a sampling port. The sampling port is positioned near the air outlet of the hair dryer to accurately collect and detect the concentration of positive and negative ions generated by the hair dryer. The wind speed testing mechanism includes an anemometer and a wind speed probe.

An insulating mounting base is used to fix both the second and third lifting cylinders to the frame, thereby achieving insulation isolation between the high-voltage test circuit and the frame.

[0013] In one possible implementation, the aging test station group is further equipped with a red glow detection mechanism and a second temperature detection mechanism. The red glow detection mechanism includes a fourth lifting cylinder, a light-shielding heat dissipation shell fixedly connected to the lifting rod inside the fourth lifting cylinder, and a CCD image sensor disposed inside the light-shielding heat dissipation shell.

[0018] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0020] To address the problems in the background technology, the present invention proposes an integrated machine for testing the aging of hair dryers, including a frame 1, a loading station 11 and a unloading station 12 disposed at both ends of the frame 1, and a transmission component 13 disposed between the loading station 11 and the unloading station 12 and capable of circulation. The transmission component 13 is provided with a plurality of positioning fixtures 14 for supporting and fixing the hair dryer. Each positioning fixture 14 is provided with a power supply interface 141 for electrically connecting the hair dryer, and a functional test station group and an aging test station group are arranged along the circulation direction of the transmission component 13. The functional test station group includes at least one functional test station spaced apart along the direction of the transmission component 13. Each functional test station is provided with a first conductive contact component 2 fixedly connected to the frame 1. Each positioning fixture 14 has a conductive wheel 142 on its end face that contacts the first conductive contact component 2. The conductive wheel 142 is electrically connected to the power supply interface 141. The aging test station group includes at least one aging station 3 arranged continuously along the direction of the transmission component 13. The aging station 3 is provided with a second conductive contact component 31 fixedly connected to the frame 1. The second conductive contact component 31 extends along the direction of the transmission component 13. When the positioning fixture 14 flows through the aging station 3, its conductive wheel 142 maintains sliding electrical contact with the second conductive contact component 31 to realize continuous power supply to the positioning fixture 14. The transmission component 13 drives each of the positioning fixtures 14 to flow through the functional test station group and the aging test station group, so that the hair dryer on the positioning fixture 14 performs functional testing in the functional test station group and aging testing in the aging test station group.

[0021] Combined with reference Figures 1 to 6 As shown, in this embodiment, the integrated machine includes a frame 1, a loading station 11, a unloading station 12, a transmission component 13, multiple positioning fixtures 14, a functional testing station group, and an aging testing station group. The frame 1, serving as the overall support structure, is constructed using aluminum profiles or steel, possessing sufficient structural strength to support the various testing components. The loading station 11 and unloading station 12 are respectively located at both ends of the frame 1. A guide ramp is provided at the loading station 11 to facilitate the operator placing the hair dryer to be tested onto the positioning fixtures 14. A loading detection sensor can be installed at the loading station 11 to detect whether the hair dryer is correctly placed on the positioning fixture 14; an unloading detection sensor is installed at the unloading station 12 to detect whether the hair dryer has been removed. Both the loading and unloading detection sensors are connected to the integrated machine's control system signal. When an abnormality is detected, the control system can issue an alarm and stop the operation of the transmission component 13.

[0022] Figure 1The equipment presents a three-dimensional frame and internal workstation layout. A transmission component 13 is positioned between the loading station 11 and the unloading station 12 to drive the positioning fixtures 14 in a cyclical manner. This transmission component 13 is preferably a ring conveyor belt, which consists of a drive motor, transmission rollers, and a ring belt body. The drive motor drives the ring belt body to circulate via the transmission rollers. Each positioning fixture 14 is installed at equal intervals on the ring belt body, and the speed of the drive motor is adjustable to control the dwell time of the positioning fixture 14 at each test station. Alternatively, a chain transmission mechanism can be used, where a sprocket drives the chain in cyclical motion, and the positioning fixtures 14 are fixed to the chain and move synchronously with it. Both implementations can have their transmission speed adjusted by a PLC controller to ensure precise dwell time of the positioning fixtures 14 at each station. The positioning fixture 14 is used to support and fix the hair dryer. Its top is equipped with a power supply interface 141 adapted to the hair dryer's power plug. The power supply interface 141 is electrically connected to the conductive wheel 142 on the end face of the positioning fixture 14 via a wire. The positioning fixture 14 can be fixed in two ways: one is an elastic gripper structure, in which the gripper is driven by a spring to clamp the hair dryer handle, which is suitable for products of different sizes; the other is a magnetic fixing structure, in which a magnetic plate is set at the corresponding position of the hair dryer handle, and an electromagnet is provided on the positioning fixture 14. When energized, a magnetic force is generated to fix the handle, making it easy to pick up and put away.

[0023] The functional testing stations are spaced apart along the direction of the transmission component 13. The first conductive contact component 2 in each station makes corresponding contact with the conductive wheel 142 of the positioning fixture 14 to achieve power supply. The first conductive contact component 2 can adopt a brush 21 structure. The brush 21 is mounted on the frame 1 through the fixing seat 24 to achieve dynamic power supply. The functional testing station group can be set up with sub-stations such as high voltage test, wind speed test, and temperature test as needed to achieve comprehensive testing of various performance aspects of the hair dryer.

[0024] The aging test station group consists of continuously arranged aging stations 3. Its second conductive contact component 31 extends along the direction of the transmission component 13, ensuring that the conductive wheel 142 maintains sliding electrical contact with the positioning fixture 14 as it flows through. The second conductive contact component 31 can take two forms: one is a conductive rail structure made of silver-plated copper with a polished surface to reduce the coefficient of friction; the other is a conductive groove 311 structure, with conductive sheets 312 embedded in the groove, limiting protrusions on both sides to prevent the conductive wheel 142 from disengaging, and an insulating buffer layer at the bottom of the groove to reduce the impact of vibration. The long-term stability of the hair dryer is verified by continuously supplying power and running it in cycles at different speeds.

[0025] During operation, the operator fixes the hair dryer to the positioning fixture 14 at the loading station 11 and connects it to the power supply interface 141. The transmission component 13 drives the positioning fixture 14 to enter the functional test station group in sequence. Various performance tests are completed by power supply through the first conductive contact component 2. When entering the aging test station group, aging verification is carried out by continuous power supply through the second conductive contact component 31. Finally, it is transferred to the unloading station 12, where the operator removes the hair dryer after testing. The positioning fixture 14 returns to the loading station 11 with the transmission component 13, completing one test cycle.

[0026] The structure of this application has the following beneficial effects: First, it saves factory space. By integrating functional testing and aging verification into the same rack 1, it reduces the floor space required compared to traditional distributed equipment, solves the problem of large space occupation for aging testing, and improves the utilization rate of production sites. Second, it replaces manual testing of single items. High automation reduces manual operation, avoids human error, and effectively improves testing efficiency. Third, it realizes data-driven and intelligent management. All test data is uploaded in real time, automatically analyzed, and reports are generated, replacing traditional paper records and improving the accuracy of production control. Fourth, it enhances the corporate image. The integrated intelligent equipment can optimize the production process.

[0027] In one possible implementation, the first conductive contact component 2 includes: The brush 21 is fixedly mounted on the frame 1 via the mounting bracket 24; The conductive connection line 22 has one end electrically connected to the brush 21 and the other end connected to an external power source for transmitting current; and The elastic support component 23 is disposed between the brush 21 and the fixed base 24, and can provide a certain elastic pressure to the brush 21, so that the brush 21 and the conductive wheel 142 are kept in close contact.

[0028] Combined with reference Figure 2As shown, in this embodiment, the first conductive contact assembly 2 is used to achieve a reliable electrical connection between the functional testing station and the positioning fixture 14. It includes a brush 21, a conductive connection line 22, and an elastic support component 23. Specifically, the brush 21 is fixedly mounted on the frame 1 via a mounting base 24. The contact end of the brush 21 uses two optional materials: one is a graphite-copper composite material, which has good conductivity and wear resistance; the other is a silver alloy. One end of the conductive connection line 22 is electrically connected to the brush 21 by crimping or welding, while the other end is connected to an external power supply or testing equipment. It can use a multi-strand copper core cable or a shielded cable, which can effectively reduce electromagnetic interference and ensure signal stability in complex electromagnetic environments such as high-voltage testing stations. The elastic support component 23 is disposed between the brush 21 and the mounting base 24 and can be a disc spring assembly, which can provide stable contact pressure within a limited installation space. The first conductive contact component 2 can automatically compensate for the minor vibrations generated during the operation of the transmission component 13 and the positional deviation of the positioning fixture 14 through the elastic support component 23, ensuring that the brush 21 and the conductive wheel 142 always maintain a tight fit.

[0029] In one possible implementation, the second conductive contact assembly 31 includes multiple conductive grooves 311 arranged side by side in the aging station 3, with conductive sheets 312 snapped into the conductive grooves 311, and the conductive wheel 142 able to slide along the conductive grooves 311 and maintain good electrical contact, thereby realizing continuous power supply to the positioning fixture 14.

[0030] Combined with reference Figure 3 As shown, in this embodiment, the second conductive contact assembly 31 is used to continuously supply power from the aging station 3 to the positioning fixture 14. It includes multiple conductive grooves 311 arranged side-by-side and conductive plates 312 snapped into the grooves. Specifically, the conductive grooves 311 can be made of high-temperature resistant engineering plastics or ceramic materials. The conductive groove 311 has a U-shaped cross-section and a slot on its bottom wall for fixing the conductive plates 312. The length of the groove matches the continuous testing area of ​​the aging station 3. Each conductive groove 311 corresponds to a sub-unit of a conductive wheel 142. When the conductive wheel 142 slides along the conductive groove 311, the wheel surface remains in close contact with the conductive plate 312. This structure solves the problems of easy tangling and unstable contact of power supply lines in traditional aging tests. Continuous power supply is achieved through the sliding contact between the conductive wheel 142 and the conductive plate 312, ensuring the hair dryer operates continuously and stably during the aging process.

[0031] In one possible implementation, the functional test station group and the aging test station group are provided with an automatic shifting mechanism 4. The automatic shifting mechanism 4 includes a plurality of drive components 41 fixed to the frame 1 and a plurality of pressing actuators 42 connected to the drive components 41. The drive components 41 can drive the pressing actuators 42 to selectively press the function buttons of the hair dryer.

[0032] Combined with reference Figure 2 As shown, in this embodiment, the automatic gear-shifting mechanism 4 is used to simulate user operation in switching the function levels of a hair dryer, realizing performance testing in multiple modes. It includes multiple drive components 41 and corresponding pressing actuators 42. The drive components 41 are fixed to the corresponding workstations of the frame 1 by brackets, and adopt two optional structures: one is a pneumatic drive component 41, and the other is an electric drive component 41. The pressing actuator 42 is connected to the output end of the drive component 41, and its contact part adopts an elastic rubber head. The built-in metal skeleton ensures structural strength, and the rubber surface can be provided with fingerprint-like paths to avoid slippage when pressing. This structure solves the problems of low efficiency and poor operation consistency caused by relying on manual gear shifting in traditional testing. Through automated control, it achieves precise synchronization of gear switching at each workstation, ensuring the comparability of functional test data and the authenticity of aging tests.

[0033] In one possible implementation, the functional test station group includes a first functional test station 5 located within the rack 1, wherein a first power test mechanism 51, a first temperature test mechanism 52, an ion test mechanism 53, and a wind speed test mechanism 54 are provided in the first functional test station 5. The first power testing mechanism 51 includes a power tester 511 electrically connected to the power supply interface 141, used to detect the power consumption of the hair dryer in the low-speed mode of cold air. The first temperature testing mechanism 52 includes a support base 521 fixedly installed at the air outlet of the hair dryer. Multiple temperature sensors 522 are evenly distributed in the support base 521, which can monitor the temperature distribution of the hair dryer in the cold air low speed mode. The ion testing mechanism 53 includes an ion tester 531 and a sampling port 532. The sampling port 532 is positioned near the air outlet of the hair dryer to accurately collect and detect the concentration of positive and negative ions generated by the hair dryer. The wind speed testing mechanism 54 includes an anemometer 541 and a wind speed probe 542. The wind speed probe 542 is set at the center of the air outlet of the hair dryer and is used to accurately measure the speed of the airflow blown out by the hair dryer in the high-speed cold air mode.

[0034] Combined with reference Figure 1 and Figure 2As shown, in this embodiment, the functional testing station group includes a first functional testing station 5 located within the rack 1. This station integrates a first power testing mechanism 51, a first temperature testing mechanism 52, an ion testing mechanism 53, and a wind speed testing mechanism 54, used to comprehensively test the performance parameters of the hair dryer under specific modes. Specifically, the first power testing mechanism 51 is electrically connected to the power supply interface 141 of the positioning fixture 14 via wires. It includes a high-precision power tester 511, supporting real-time data upload. This mechanism is specifically designed to test the power consumption of the hair dryer in the low-speed cold air mode (only the fan is running and the speed is at the lowest setting), ensuring that the energy consumption under basic operating conditions meets the design standards. The first temperature testing mechanism 52 includes a support base 521 fixed to the rack 1. The support base 521 is made of heat-insulating material, and 4-6 temperature sensors 522 (such as thermocouples) are evenly distributed on its end face facing the hair dryer's air outlet, forming a ring detection array. In the low-speed cold air mode, the sensors collect the air outlet temperature in real time, which can effectively detect whether there is abnormal heating.

[0035] Furthermore, the ion testing mechanism 53 consists of an ion tester 531 and a sampling port 532. The sampling port 532 is fixed to the frame 1 via a metal tube, facing the center of the hair dryer's air outlet and maintaining a certain distance to ensure the accuracy of ion collection. The ion tester 531 can simultaneously detect the concentration of positive and negative ions to verify the effectiveness of the negative ion function. The wind speed testing mechanism 54 includes an anemometer 541 and a wind speed probe 542. The wind speed probe 542 is either a hot-wire type or an impeller type, fixed to the center of the hair dryer's air outlet via a bracket. During testing, the automatic shifting mechanism 4 switches the hair dryer to the high-speed cold air mode, and the anemometer 541 records the wind speed value in real time.

[0036] The first functional test station 5 integrates multiple functional testing mechanisms, solving the problems of cumbersome processes and low efficiency caused by individual testing of single parameters in traditional testing. It enables continuous testing of power, temperature, ion concentration, and wind speed in cold air mode, ensuring the correlation and accuracy of test data.

[0037] In one possible implementation, the functional test station group further includes a second functional test station 6 disposed within the rack 1, wherein a second power test mechanism 61 and an indicator light test mechanism 62 are disposed within the second functional test station 6. The second power testing mechanism 61 is used to detect the power consumption of the hair dryer in low temperature and low speed, low temperature and high speed, high temperature and low speed, high temperature and high speed and cold air high speed modes respectively. The indicator light testing mechanism 62 includes an image acquisition device 621 and an image analysis module 622 electrically connected thereto, wherein the image acquisition device 621 is aimed at the indicator light area of ​​the hair dryer.

[0038] Combined with reference Figure 1and Figure 2 As shown, in this embodiment, the functional test station group also includes a second functional test station 6 located within the frame 1. This station can test the multi-mode power and indicator lights of the hair dryer, and is equipped with a second power test mechanism 61 and an indicator light test mechanism 62. The second power test mechanism 61 has the same structure as the first power test mechanism 51 described above. When the hair dryer in the fixture enters the second functional test station 6, the automatic shift mechanism 4 sequentially switches the hair dryer to low temperature and low speed, low temperature and high speed, high temperature and low speed, high temperature and high speed, and cold air and high speed modes according to preset logic. The power tester 511 collects the power consumption data under the corresponding working conditions, and the data is transmitted to the control system for storage and analysis in real time to ensure that the power parameters of each gear meet the design standards.

[0039] The indicator light testing mechanism 62 consists of a high-definition image acquisition device 621 and an image analysis module 622. The image acquisition device 621 uses an industrial camera equipped with a ring light source to eliminate reflection interference, and the lens focal length is adapted to the size of the indicator light area to ensure clear capture of indicator light details. The image analysis module 622 has a built-in image recognition algorithm that can automatically identify the on / off state, color, and flashing frequency of the indicator light. During testing, the image acquisition device 621 captures images as the hair dryer mode changes, and the analysis module compares them with preset standards to determine whether the indicator light changes according to the specified response mode.

[0040] The second functional test station 6 solves the problems of cumbersome power detection in multiple modes and reliance on manual visual judgment of indicator light status in traditional testing. Through automatic mode switching and data acquisition, it achieves comprehensive detection of power parameters.

[0041] In one possible implementation, the functional test station group further includes a third functional test station 7 located within the rack 1. The third functional test station 7 is equipped with a third power test mechanism 71, which is used to detect the power consumption of the hair dryer in high temperature and high speed mode.

[0042] Combined with reference Figure 4 As shown, in this embodiment, the functional testing station group also includes a third functional testing station 7 located within the frame 1. This station is close to the unloading station 12 and located after the aging test station group. It is specifically used for retesting the power output of the hair dryer under high-temperature, high-speed mode after the aging test. During the test, the automatic shifting mechanism 4 precisely switches the hair dryer to the high-temperature, high-speed mode. The third power testing mechanism 71 continuously collects power data, takes the average value as the final test result, and compares and analyzes it with the initial power data before the aging test. This structure, located after the aging test and before the unloading, solves the problem of traditional testing where power testing is only performed once before aging, making it impossible to verify the impact of the aging process on power stability. The retest ensures that the hair dryer can maintain normal power output after long-term high-temperature, high-load operation.

[0043] In one possible implementation, a high-pressure resistance test station 8 is further provided inside the frame 1 near the unloading station 12, and the high-pressure resistance test station 8 is equipped with: The high voltage tester 81 is fixed inside the frame 1 and is used to output a preset high voltage test voltage; The second lifting cylinder 82 is fixedly installed below the high-pressure test station 8 corresponding to the frame 1; The first conductive foam 83 is fixedly connected to the lifting rod of the second lifting cylinder 82 and electrically connected to the high voltage tester 81. The second lifting cylinder 82 can drive the first conductive foam 83 to rise and abut against the metal shell at the air outlet of the hair dryer. The third lifting cylinder 84 is fixed above the high-pressure test station 8 corresponding to the frame 1; The second conductive foam is fixedly connected to the lifting rod of the third lifting cylinder 84 and electrically connected to the high voltage tester 81. The third lifting cylinder 84 can drive the second conductive foam to move horizontally and abut against the metal shell at the air inlet of the hair dryer. Insulating mounting base 85; second conductive foam; 86, the second lifting cylinder 82 and the third lifting cylinder 84 are both fixed to the frame 1 through the insulating mounting base 85; second conductive foam; 86 to achieve insulation isolation between the high voltage test circuit and the frame 1.

[0044] Combined with reference Figure 4 As shown, in this embodiment, a high-voltage test station 8 is provided on the side of the frame 1 near the unloading station 12. This station is located after the aging test station group and before the unloading station 12. It is used to perform the final insulation safety performance test on the hair dryer that has undergone the aging test. The station is equipped with a high-voltage tester 81, a second lifting cylinder 82, a first conductive foam 83, a fourth lifting cylinder 321, a second conductive foam and an insulating mounting base 85; the second conductive foam; 86.

[0045] Specifically, the high-voltage tester 81 is fixed in the mounting compartment at the top of the frame 1. The second lifting cylinder 82 is fixed to the bottom of the high-voltage testing station 8 via an insulating mounting base 85 and a second conductive foam 86. It is pneumatically or electrically driven, and an insulating gasket is provided between the cylinder body and the frame 1 to prevent high voltage conduction to the frame 1. The conductive foam is round or square, with an embedded metal mesh to ensure conductivity, and a conductive cloth covering the surface, ensuring reliable contact with the metal casing of the hair dryer while preventing scratches on the product surface. The first conductive foam 83 is fixedly connected to the lifting rod of the second lifting cylinder 82 via an insulating bracket; the second conductive foam is also fixedly connected to the lifting rod of the second lifting cylinder 82 via an insulating bracket. Both conductive foams are connected to the output terminal of the high-voltage tester 81 via high-voltage wires.

[0046] During testing, when the positioning fixture 14 moves the hair dryer into the workstation, the second lifting cylinder 82 drives the first conductive foam 83 to rise, making it tightly abut against the metal shell at the air inlet of the hair dryer. Meanwhile, the third lifting cylinder 84 drives the second conductive foam to move horizontally and fit against the metal shell at the air inlet. Simultaneously, the high-voltage tester 81 applies a preset high voltage through the power supply interface 141. This structure solves the problems of traditional high-voltage resistance testing requiring manual wiring, low efficiency, and safety hazards. It achieves unmanned operation of high-voltage testing through automated lifting contact and, being placed after aging testing, can effectively verify the insulation stability of the hair dryer after long-term use.

[0047] In one possible implementation, the aging test station group is further provided with a red glow detection mechanism 32 and a second temperature detection mechanism 33; The red glow detection mechanism 32 includes a fourth lifting cylinder 321, a light-shielding heat dissipation shell 322 fixedly connected to the lifting rod inside the fourth lifting cylinder 321, and a CCD image sensor 323 disposed inside the light-shielding heat dissipation shell 322. The fourth lifting cylinder 321 can push the CCD image sensor 323 close to the heating wire of the hair dryer to detect the red glow of the heating wire in the high temperature and high speed mode. The second temperature detection mechanism 33 is used to monitor the temperature distribution of the hair dryer in high temperature and high speed mode.

[0048] Combined with reference Figure 1 , Figure 3 and Figure 5 As shown, in this embodiment, the aging test station group is equipped with a red glow detection mechanism 32 and a second temperature detection mechanism 33, which are used to monitor the working status of the core components of the hair dryer in real time during the aging process to ensure its high-temperature operation stability. The red glow detection mechanism 32 includes a lifting cylinder, a light-shielding heat dissipation shell 322, and a CCD image sensor 323. The lifting cylinder is fixed to the top of the frame 1 and is driven by a servo motor. The detection distance can be adjusted according to the hair dryer model. The light-shielding heat dissipation shell 322 is fixedly connected to the lifting rod of the lifting cylinder. The shell is made of aluminum alloy and has heat dissipation fins. The inside is lined with black light-absorbing cotton, which can not only isolate external light interference, but also control the temperature inside the shell through a built-in micro fan to avoid high temperature affecting the accuracy of the sensor. The CCD image sensor 323 is fixed inside the light-shielding heat dissipation shell 322 and can clearly capture the red glow state of the heating wire in the high-temperature and high-speed mode. During the test, the lifting cylinder pushes the light-shielding heat dissipation shell 322 down so that the lens is aimed at the heating wire area of ​​the hair dryer. The image analysis is used to determine whether the red glow of the heating wire is uniform and whether there are any local overly bright or dark areas. The second temperature detection mechanism 33 has the same structure as the first temperature detection mechanism. During the high-temperature and high-speed aging process, the sensor collects the air outlet temperature and distribution data in real time.

[0049] This structure solves the problem of difficulty in intuitively monitoring the state and temperature distribution of the heating wire in traditional aging tests. The working state of the heating wire can be directly observed through the red glow detection mechanism 32. Combined with the multi-point temperature measurement of the second temperature detection mechanism 33, the core performance changes of the hair dryer during high temperature and high load aging process can be fully grasped, and potential risks such as local overheating and abnormal heating wire can be detected in time, effectively improving the pertinence and effectiveness of aging tests.

[0050] In summary, the technical solution of this invention integrates the functional testing station group and the aging testing station group into one unit, and uses a circulating transmission component to achieve continuous automated flow of the positioning fixture, significantly improving the synchronous production capacity between the hair dryer testing line and the assembly and packaging line. This integrated design not only saves a significant amount of factory space and reduces manual intervention and handling, but also ensures continuous and stable power supply for testing through the cooperation of conductive wheels and dynamic elastic contact structures, effectively avoiding the risks of cable entanglement and contact sparks, and substantially improving testing reliability. The system integrates multiple functional testing mechanisms and an automatic shifting unit, which can fully support the testing needs of products with multiple working modes, such as hair dryers, and achieve accurate acquisition and data processing of multiple test parameters. Test results are automatically saved and support integration with the MES system, realizing digital intelligent manufacturing and further enhancing market competitiveness.
