Description

Technical Field

[0001] This utility model relates to the technical field of workpiece testing, and in particular to a synchronous testing device and the resulting air conditioning cabinet indoor unit production system. Background Technology

[0002] In the current production process of air conditioner cabinet indoor units, product performance testing is a crucial step in ensuring product quality. Traditional testing methods for air conditioner cabinet indoor units require manual visual inspection or single-point testing equipment. These traditional testing methods have the following drawbacks:

[0003] 1. Production efficiency: The need for inspection of each unit during the production process leads to a longer production line cycle time, which cannot meet the needs of modern high-speed production.

[0004] 2. Poor adaptability: Difficult to adapt to rapid switching between testing of products of different specifications.

[0005] 3. Poor consistency of test results: The test process uses a board-chain power supply and manual clamp meter measurement of electrical parameters, resulting in poor consistency of test results.

[0006] 4. Insufficient dynamic control: Unable to dynamically adjust production line operating parameters such as production speed and handling of abnormal machine types based on real-time test results.

[0007] 5. High labor costs: To meet production demands and resolve production bottlenecks, up to 12 people working in two shifts are required to meet production needs.

[0008] To improve testing efficiency, patent CN112731032B discloses a safety testing system and method. The safety testing system includes: a first conveying structure and a second conveying structure. The first conveying structure is mounted on a frame for conveying connecting components, and the second conveying structure is used for conveying the indoor unit of an air conditioner; a robotic arm; when the second conveying structure conveys the indoor unit to a preset area, the robotic arm grips the power plug to insert it into a socket. In this technical solution, the safety testing instrument remains fixed in position, and the indoor unit is tested through the synchronous movement of the connecting components and the indoor unit. This technical solution enables automatic connection between the safety testing instrument and the indoor unit; however, there is only one safety testing instrument, and only one indoor unit can be tested at a time, severely limiting the testing efficiency. Furthermore, the movement of the connecting components extends the power supply lines, resulting in complex wiring layouts and affecting wiring efficiency. Utility Model Content

[0009] To overcome the problems existing in related technologies, one of the objectives of this utility model is to provide a synchronous testing device that ensures that the workpiece under test can be tested synchronously during the transmission of the workpiece along the first transmission line, thereby improving the testing efficiency of the workpiece under test. It does not require additional testing time or additional testing processes, thus improving both the testing efficiency and production efficiency of the workpiece under test.

[0010] A synchronous testing device, comprising:

[0011] The first transmission line is used to transmit the workpiece to be tested;

[0012] A second transmission line operates synchronously with the first transmission line, and the second transmission line is provided with a plurality of detectors at intervals; the detectors are slidably connected to the power supply line through power supply components, and the detectors are electrically connected to the workpiece to be tested through plug-in components.

[0013] This application ensures that the workpiece under test can be inspected simultaneously while it is being transported along the first transmission line, thus improving the inspection efficiency of the workpiece under test. It does not require additional inspection time or additional inspection processes, thereby improving both the inspection efficiency and production efficiency of the workpiece under test.

[0014] In a preferred embodiment of this invention, the synchronous testing device further includes a power supply rail, wherein the power supply rail, the power supply line, and the second transmission line are parallel to each other, and the power supply component is slidably connected to the power supply rail.

[0015] This application allows for the placement of detectors fixed within a second transmission line. This second transmission line drives several detectors to move synchronously. Since the detectors are connected to the power supply line via a sliding contact mechanism, and the power supply line is parallel to the second transmission line, the length of the power supply component is minimized, ensuring its adaptability to each detector and simplifying the overall device structure. To ensure the power supply component moves smoothly and synchronously during detector movement, this application places the power supply component in a power supply track, parallel to both the second transmission line and the power supply line. This ensures the power supply component can move synchronously with the detector along the power supply track. In this application, one end of the power supply component is fixedly connected to the detector, and the other end is slidably connected to the power supply line. Simultaneously, the middle position of the power supply component is slidably connected to the power supply track. The purpose of the power supply track is to ensure the power supply component can slide synchronously with the detector, preventing the power supply component from detaching from the detector due to insensitive contact between the power supply component and the power supply line.

[0016] In a preferred embodiment of this invention, the power supply component is connected to the power supply track via a guide component, the power supply component is fixedly connected to the guide component, and the guide component is slidably connected to the power supply track.

[0017] The guide is designed to connect the power supply component and the power supply track. The two ends of the power supply component are connected to the power supply line and the detector, respectively. The middle position needs to be fixed in the power supply track by the guide. The guide is fixedly connected to the power supply component and simultaneously slidably connected to the power supply track. As the second transmission line moves the detector, the power supply component and the guide move synchronously with the detector. The power supply track and the power supply line remain stationary, while the guide drives the power supply component to slide along the power supply track. This structural design ensures that the power supply component is always in sliding contact with the power supply line and always slidably connected to the power supply track, improving the stability of the power supply component's movement and ensuring stable power supply to the detector.

[0018] In a preferred embodiment of this invention, the guide includes at least two locking wheels, and the plurality of locking wheels are symmetrically arranged on both sides of the power supply track, and the locking wheels slide against the power supply track.

[0019] The guide component can be centered on the power supply rail, with two symmetrically arranged locking wheels on the upper and lower sides of the power supply rail. These two locking wheels slide against the upper and lower sides of the power supply rail respectively, ensuring that the guide component can engage with the power supply rail and slide relative to it via the locking wheels. In actual operation, two sets of symmetrically arranged locking wheels can be used to ensure a smooth and stable connection between the guide component and the power supply rail.

[0020] In a preferred embodiment of this invention, the second transmission line includes a suspension chain, the suspension chain includes a cyclically arranged suspension track, the suspension track is provided with suspension hangers at intervals, the top of the detector is provided with a snap-fit ​​hanger, and the suspension hangers and snap-fit ​​hangers are fixedly connected.

[0021] The suspension track is an elliptical ring structure to enable the cyclic movement of the detector. Suspension hangers are spaced along the track, and corresponding snap-fit ​​hangers are installed at the top of the detector. Connecting the suspension hangers and snap-fit ​​hangers together secures the detector to the suspension track. A tensioning mechanism is located on the outer side of the suspension track. The suspension track and tensioning mechanism form a chain motion track, in which a chain is fixed, and the suspension hangers are positioned within the chain. A motor drives the chain, enabling its movement along the chain motion track, and thus the movement of the detector within the chain. This second transmission line structure allows for cyclic detection, improving detection efficiency and detector utilization.

[0022] In a preferred embodiment of this invention, a support rail is provided on the side and / or bottom of the suspension rail, and a guide wheel is provided in the detector, the guide wheel being slidably connected to the support rail.

[0023] Since the detector in this application is suspended below the suspension track, in order to ensure the stability of the detector's movement, a support track is provided below the suspension track and connected to the support track through the guide wheels at the bottom of the detector. The support track provides support force for the detector, ensuring that the detector can move smoothly and steadily, and improving the service life of the detector.

[0024] In a preferred embodiment of this invention, the detector is equipped with a barcode scanner, and the workpiece to be tested is equipped with a marking code, which is used to indicate the information and test items corresponding to the workpiece to be tested.

[0025] When the workpiece under test moves to the position coinciding with the second transmission line, the barcode scanner in the detector scans the marking code on the workpiece to obtain the test program. The detector then starts the test based on this program. The combination of the barcode scanner and the marking code enables automatic detection of the workpiece, further improving detection efficiency and automation.

[0026] In a preferred embodiment of this invention, the detector includes at least one of an electrical safety testing component, a cooling performance testing component, an infrared thermal imaging testing component, a pressure detection component, a noise and vibration testing component, and a triaxial vibration sensor testing component.

[0027] The second objective of this application is to provide an air conditioner cabinet indoor unit production system, including a synchronous testing device as described above.

[0028] The aforementioned synchronous testing device can be installed at each stage of the production and transportation of the air conditioning unit, so as to ensure that the testing can be completed during the transmission or assembly of the air conditioning unit, thereby improving the testing and assembly efficiency of the air conditioning unit.

[0029] Because the first and second transmission lines operate synchronously, the workpiece under test can be tested during transportation, which improves the testing efficiency of the workpiece under test and does not affect the normal transmission of the workpiece under test.

[0030] The beneficial effects of this utility model are as follows:

[0031] This utility model provides a synchronous testing device, comprising a first transmission line and a second transmission line operating synchronously. The first transmission line is used to transport the workpiece to be tested. Multiple detectors are spaced apart on the second transmission line, and each detector is slidably connected to the power supply line via a power supply component. The detectors are electrically connected to the workpiece to be tested via connectors. When the workpiece to be tested moves along the first transmission line to the side of the second transmission line, the connectors electrically connect the workpiece to one of the detectors, thus establishing a signal connection between the detector and the workpiece. Simultaneously, the power supply line remains stationary, while the power supply component can slide relative to the power supply line to supply power to the detector. This ensures that the workpiece to be tested can be tested synchronously while it is being transported along the first transmission line, improving the testing efficiency of the workpiece without requiring additional testing time or additional testing processes, thereby increasing both the testing efficiency and production efficiency. In addition, the detector and the power supply line of this application are connected by a sliding power supply component, that is, one end of the power supply component is electrically connected to the detector, and the other end can slide relative to the power supply line to realize a sliding contact electrical connection. In this way, there is no need to set up extra wires, the wiring is simple and convenient, and the installation and wiring efficiency of the synchronous test device is improved.

[0032] This application also provides a production system for air conditioning cabinet indoor units, including the synchronous testing device described above. The synchronous testing device can be set up at each stage of the production and transportation of the air conditioning cabinet indoor unit to ensure that the testing can be completed during the transmission or assembly of the air conditioning cabinet indoor unit, thereby improving the testing efficiency and assembly efficiency of the air conditioning cabinet indoor unit.

For example, without departing from the scope of this invention, first information may also be referred to as second information, and similarly, second information may also be referred to as first information. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0045] Example 1

[0046] like Figures 1-7 As shown, the synchronous testing device provided in this application includes:

[0047] The first transmission line 11 is used to transmit the workpiece 12 to be tested;

[0048] A second transmission line 21 operates synchronously with the first transmission line 11. The second transmission line 21 is provided with a plurality of detectors 22 at intervals. The detectors 22 are slidably connected to the power supply line 24 through a power supply component. The detectors 22 are electrically connected to the workpiece 12 to be tested through a connector.

[0049] The purpose of synchronous operation of the first transmission line 11 and the second transmission line 21 in this application is to ensure that the workpiece 12 under test is tested during its transmission. Specifically, the transmission of the workpiece 12 can refer to any stage of the assembly and transportation process. An example is given below:

[0050] When the workpiece 12 to be tested is an indoor unit of an air conditioning cabinet, the indoor unit of the air conditioning cabinet is assembled in the assembly line from the first process until the assembly is completed. For this device, the indoor unit of the air conditioning cabinet needs to be transferred between various processes in the first transmission line 11. In the same process, it also needs to be transferred from the inlet to the outlet. In this application, the first transmission line 11 refers to any transmission line in the assembly process of the indoor unit of the air conditioning cabinet. It can be a transmission line between two processes, a transmission line in the same process, or the final warehousing and packaging transmission line, etc.

[0051] Correspondingly, the detector 22 can be designed according to the assembly requirements of the indoor unit of the air conditioning cabinet. It can be used to test the final product or to test the semi-finished product after one of the processes is completed. For example, after the heat exchanger in the indoor unit of the air conditioning cabinet is installed, it is necessary to test the cooling performance of the indoor unit. In this case, the corresponding detector 22 and the second transmission line 21 can be set inside the heat exchanger installation process, or on the transmission line between the heat exchanger installation process and the next process. When the second transmission line 21 is set inside the heat exchanger installation process, it needs to be specifically installed on the side of the transmission line after the heat exchanger is assembled to ensure that the cooling performance of the indoor unit of the air conditioning cabinet can be tested during the transmission process after the heat exchanger is installed.

[0052] It should be noted that in existing technologies, the indoor unit of the air conditioning cabinet needs to undergo corresponding process operations first, and then additional inspection processes are set up to test it. The purpose of this application is to merge the inspection process into the preceding assembly process, eliminating the need for additional inspection processes and tooling, thereby improving the assembly and inspection efficiency of the indoor unit of the air conditioning cabinet.

[0053] When the workpiece 12 to be tested in this application is another workpiece that needs to be assembled, the design concept is the same as described above, and will not be explained one by one.

[0054] The detector 22 and the component under test (DUT) are connected via a connector to enable signal transmission and feedback. Specifically, one end of the connector is plugged into the plug in the detector 22, and the other end is plugged into the plug in the DUT 12. In practice, it can be ensured that one end of the connector remains connected to the detector 22 at all times. When the DUT 12 moves to the side of the second transmission line 21 along the first transmission line 11, the connector in the detector 22 can be manually or robotically plugged into the DUT 12. Similarly, when the test is completed, the corresponding connector can be manually or robotically removed from the DUT 12.

[0055] In this application, detector 22 needs to be connected to a power source to ensure its normal operation. Since the component under test and detector 22 move synchronously, meaning detector 22 is in a moving state, directly connecting detector 22 to the power source via wires would require multiple detectors to move multiple wires, resulting in a cumbersome and messy wire layout and affecting detection efficiency. This application uses a fixed power supply line 24, and designs the detector 22 to slide relative to the power supply line 24 via a power supply component. Specifically, one end of the power supply component is electrically connected to the detector 22 (through a plug-in connection), and the other end is slidably connected to the power supply line 24. Power can be supplied to the external source from various positions on the power supply line 24. As the power supply component moves with the detector 22, it can slide relative to the power supply line 24. Thus, by ensuring that the power supply line 24 and the second transmission line 21 remain parallel, the detector 22 can be fixed while maintaining the fixed size of the power supply component. Furthermore, during the synchronous movement of multiple detectors 22, multiple power supply components make sliding contact with the power supply line 24, which not only ensures normal power supply to the detectors 22, but also avoids cumbersome wiring structures.

[0056] When the workpiece 12 under test moves along the first transmission line 11 to the side of the second transmission line 21, the workpiece 12 under test and one of the detectors 22 are electrically connected through a connector to realize the signal connection between the detector 22 and the workpiece 12 under test. At the same time, the power supply line 24 is fixed and the power supply component can slide relative to the power supply line 24 to supply power to the detector 22. This ensures that the workpiece 12 under test can be detected synchronously during the transmission of the workpiece 12 along the first transmission line 11, which improves the detection efficiency of the workpiece 12 under test. It does not require additional detection time or additional detection processes, thus improving the detection efficiency and production efficiency of the workpiece 12 under test.

[0057] In addition, the detector 22 and the power supply line 24 of this application are connected by a sliding power supply component. That is, one end of the power supply component is electrically connected to the detector 22, and the other end can slide relative to the power supply line 24 to achieve a sliding contact electrical connection. In this way, there is no need to set up extra wires, the wiring is simple and convenient, and the installation and wiring efficiency of the synchronous test device is improved.

[0058] Example 2

[0059] like Figures 1-7 As shown, the synchronous testing device provided in this application includes:

[0060] The first transmission line 11 is used to transmit the workpiece 12 to be tested;

[0061] A second transmission line 21 operates synchronously with the first transmission line 11. The second transmission line 21 is provided with a plurality of detectors 22 at intervals. The detectors 22 are slidably connected to the power supply line 24 through a power supply component. The detectors 22 are electrically connected to the workpiece 12 to be tested through a connector.

[0062] Furthermore, the synchronous testing device also includes a power supply rail 25, wherein the power supply rail 25, the power supply line 24, and the second transmission line 21 are parallel to each other, and the power supply component is slidably connected to the power supply rail 25.

[0063] This application allows for the detector 22 to be fixed within the second transmission line 21. The second transmission line 21 drives several detectors 22 to move synchronously. Since the detectors 22 are connected to the power supply line 24 via a sliding contact via a power supply component, and the power supply line 24 is positioned parallel to the second transmission line 21, the length of the power supply component is minimized, and its compatibility with each detector 22 is ensured, simplifying the overall device structure. To ensure that the power supply component moves synchronously and smoothly during the movement of the detectors 22, this application places the power supply component within a power supply track 25. The power supply track 25 is parallel to both the second transmission line 21 and the power supply line 24, ensuring that the power supply component can move synchronously with the detectors 22 along the power supply track.

[0064] Note: In this application, one end of the power supply component is fixedly connected to the detector 22, and the other end is slidably connected to the power supply line 24. At the same time, the middle position of the power supply component is slidably connected to the power supply slide rail. The purpose of setting the power supply slide rail is to ensure that the power supply component can slide synchronously with the detector 22 under the drive of the detector 22, and to avoid the power supply component and the power supply line 24 from being detached from the detector 22 due to insensitive sliding contact.

[0065] In this application, the side of the power supply component that connects to the detector 22 can be a plug structure, which is plugged into the socket in the detector 22. The side of the power supply component that connects to the power supply line 24 can be a conductive pulley or a wire post, which contacts the power supply line 24 and can slide relative to it.

[0066] Furthermore, in this application, the power supply component is connected to the power supply track 25 via the guide 226, the power supply component is fixedly connected to the guide 226, and the guide 226 is slidably connected to the power supply track 25.

[0067] The guide component 226 is provided to connect the power supply component and the power supply track 25. The two ends of the power supply component are connected to the power supply line 24 and the detector 22, respectively. The middle position needs to be fixed in the power supply track 25 by the guide component 226. The guide component 226 is fixedly connected to the power supply component and slidably connected to the power supply track 25. During the movement of the detector 22 driven by the second transmission line 21, the power supply component and the guide component 226 move synchronously with the detector 22. The power supply track 25 and the power supply line 24 remain stationary. The guide component 226 drives the power supply component to slide along the power supply track 25. Through this structural design, it can be ensured that the power supply component is always in sliding contact with the power supply line 24 and is always slidably connected to the power supply track 25, which improves the stability of the movement of the power supply component and ensures that the detector 22 is powered smoothly.

[0068] As a specific embodiment, the guide 226 in this application includes at least two locking wheels 2261, and the plurality of locking wheels 2261 are symmetrically arranged on both sides of the power supply track 25, and the locking wheels 2261 slide against the power supply track 25.

[0069] like Figure 6 and Figure 7 As shown, the guide member 226 can be symmetrically arranged with two engaging wheels 2261 on the upper and lower sides of the power supply rail 25, with the power supply rail 25 as the center. The two engaging wheels 2261 slide against the upper and lower sides of the power supply rail 25 respectively to ensure that the guide member 226 can engage with the power supply rail 25 and slide relative to it through the engaging wheels 2261. In actual operation, two sets of symmetrically arranged engaging wheels 2261 can be set to ensure that the guide member 226 can be stably connected to the power supply rail 25 and slide smoothly.

[0070] Furthermore, the detector 22 is provided with an adjusting rod 227. One end of the adjusting rod 227 is fixed in the detector 22, and the other end of the adjusting rod 227 extends toward the power supply rail 25, that is, the adjusting rod 227 is set perpendicular to the power supply rail 25. The guide member 226 is fixed in the adjusting rod 227 by a fastening assembly, and the position of the guide member 226 in the adjusting rod 227 is movable; when it is necessary to move the guide member 226, the fastening assembly is loosened and the position of the guide member 226 is moved; after the guide member 226 is moved into place, the fastening assembly is tightened to fix the guide member 226.

[0071] Since the power supply slide rail and the power supply line 24 are parallel, the guide member 226 is located in the power supply slide rail. One end of the power supply component is slidably connected to the power supply line 24, and the other end is fixedly connected to the detector 22. The guide member 226 is fixedly connected in the middle. In this application, the position of the power supply line 24 is fixed, while the position of the power supply track 25 can be moved closer to or further away from the second transmission line 21. By adjusting the position of the guide member 226 in the adjusting rod 227, the distance between the power supply track 25 and the second transmission line 21 can be adjusted to accommodate different models of power supply components and ensure smooth and stable movement of the power supply component.

[0072] Example 3

[0073] like Figures 1-7 As shown, the synchronous testing device provided in this application includes:

[0074] The first transmission line 11 is used to transmit the workpiece 12 to be tested; the first transmission line 11 is a transmission line extending in the horizontal direction.

[0075] A second transmission line 21 operates synchronously with the first transmission line 11. The second transmission line 21 is provided with a plurality of detectors 22 at intervals. The detectors 22 are slidably connected to the power supply line 24 through a power supply component. The detectors 22 are electrically connected to the workpiece 12 to be tested through a connector.

[0076] The second transmission line 21 is a cyclic transmission line, meaning it is driven by cyclic power to move the detector 22 within the annular space. Furthermore, the second transmission line 21 is located to the side of the first transmission line 11.

[0077] Specifically, the second transmission line 21 includes a suspension chain, the suspension chain includes a cyclically arranged suspension track, the suspension track is provided with suspension hangers at intervals, and the top of the detector 22 is provided with a snap-fit ​​hanger 228, the suspension hanger and the snap-fit ​​hanger 228 are fixedly connected.

[0078] like Figures 1-3 As shown, the suspension track is an elliptical ring structure to enable the cyclic movement of the detector 22. Suspension hangers are spaced along the suspension track, and a corresponding snap-fit ​​hanger 228 is installed at the top of the detector 22. By snapping the suspension hangers and snap-fit ​​hangers 228 together, a fixed connection between the detector 22 and the suspension track is achieved. A tensioning mechanism is installed on the outside of the suspension track. The suspension track and the tensioning mechanism form a chain motion track, in which a chain is fixed, and the suspension hangers are positioned within the chain. A motor drives the chain, enabling its movement within the chain motion track, thereby moving the detector 22 within the chain. This structure of the second transmission line 21 enables the cyclic movement and detection of the detector 22, improving detection efficiency and the utilization rate of the detector 22.

[0079] In this application, the first transmission line 11 is a horizontal transmission line, and the second transmission line 21 is a loop transmission line. To ensure the smooth progress of the detection process, the transmission speed of the first transmission line 11 and the second transmission line 21 can be determined by the detection time, ensuring that the workpiece 12 under test completes the detection within the area overlapping with the second transmission line 21. Taking the first transmission line 11 running from left to right as an example, when the first transmission line 11 moves the workpiece 12 under test to a position overlapping with the left side of the second transmission line 21, the detector 22 and the workpiece 12 under test are electrically connected, and monitoring begins; when the first transmission line 11 moves the workpiece 12 under test to a position overlapping with the right side of the second transmission line 21, the detection is completed, the detector 22 and the workpiece 12 under test are separated, and the first transmission line 11 moves the workpiece 12 under test to the next process.

[0080] The suspension track described in this application is provided with a support track 23 on its side and / or bottom, and the detector 22 is provided with a guide wheel 225, which is slidably connected to the support track 23.

[0081] Since the detector 22 is suspended below the suspension track in this application, in order to ensure the stability of the detector 22's movement, a support track 23 is provided below the suspension track, and the detector 22 is connected to the support track 23 through the guide wheel 225 at the bottom of the detector 22. The support track 23 provides support force for the detector 22, ensuring that the detector 22 can move smoothly and steadily, and improving the service life of the detector 22.

[0082] To ensure the stability of the suspension track, this application places the suspension track within a T-shaped support frame 31. The T-shaped support frame 31 provides support for the suspension track, ensuring its stability. Additionally, this application includes multiple support columns 32 on the inner side of the annular suspension track. These support columns 32 support the suspension track, giving it a certain height for easy connection to the workpiece 12 to be measured.

[0083] This application may also provide a support rail 23 on the side of the detector 22. Similarly, a guide wheel 225 is provided on the side of the detector 22. The guide wheel 225 is located in the support rail 23. The side support rail 23 is used to prevent the detector 22 from shaking in the suspension rail.

[0091] The power supply rail 25, power supply line 24, and second transmission line 21 are parallel to each other, and the power supply component is slidably connected to the power supply rail 25. The power supply component is connected to the power supply rail 25 via a guide 226, and the power supply component is fixedly connected to the guide 226, while the guide 226 is slidably connected to the power supply rail 25. The guide 226 includes at least two locking wheels 2261, and multiple locking wheels 2261 are symmetrically arranged on both sides of the power supply rail 25, with the locking wheels 2261 slidably abutting against the power supply rail 25.

[0093] The detector 22 is slidably connected to the power supply line 24 via a power supply component; wherein, the side of the power supply component connected to the detector 22 can be a plug structure, which is plugged into a socket in the detector 22. The side of the power supply component connected to the power supply line 24 can be a conductive pulley or a wire post, which is in contact with the power supply line 24 and can slide relative to it.

[0094] The first transmission line 11 transmits the workpiece 12 to be tested to the side position of the second transmission line 21; the barcode scanner in the detector 22 scans the marking code in the workpiece 12 to obtain the test program corresponding to the workpiece 12.

[0095] The workpiece 12 to be tested is electrically connected to one of the detectors 22 in the second transmission line 21; the detector 22 begins to test the workpiece 12 according to the acquired test program. During the testing process, the first transmission line 11 and the second transmission line 21 operate synchronously, allowing the workpiece 12 to complete the test during transportation. As the second transmission line 21 moves the detector 22, the power supply component and the guide component 226 move synchronously with the detector 22, while the power supply track 25 and the power supply line 24 remain stationary, and the guide component 226 drives the power supply component to slide along the power supply track 25. The top of the detector 22 moves with the second transmission line 21, and the bottom and side guide wheels 225 slide along the corresponding support tracks 23.

[0098] The system also includes a second transmission line 21, which comprises a suspension chain and a cyclically arranged suspension track. Suspension hangers are spaced apart along the suspension track, and a snap-fit ​​hanger 228 is fixedly connected to the top of each detector 22. Several detectors 22 are spaced apart along the suspension track. Each detector 22 is slidably connected to a power supply line 24 via a power supply component and is electrically connected to the indoor unit of the air conditioning unit via a connector. The system also includes a power supply track 25, which is parallel to the power supply line 24 and the second transmission line 21.
