Description

Technical Field

[0001] This invention relates to a testing device for an air conditioning control panel assembly, belonging to the field of automotive components. Background Technology

[0002] As the core control component of an air conditioning system, the air conditioning control panel assembly directly determines the user experience and reliability of the end product. This is due to factors such as the continuity of its internal circuits, the electrical performance of its electronic components, the mechanical transmission quality of its buttons and knobs, as well as the panel's appearance and indicator light brightness. On the production assembly line, the assembled air conditioning control panel assemblies undergo comprehensive performance testing to screen out defective products with circuit faults, stuck buttons, abnormal torque, or cosmetic defects.

[0003] Current testing methods mostly employ segmented or semi-manual approaches, where electrical performance testing, mechanical testing, and visual inspection are performed at different workstations or on separate instruments. This decentralized testing structure leads to frequent turnover of panel assemblies between different workstations, resulting in low testing efficiency, high labor intensity, and a high risk of secondary scratches on the panel surface during repeated clamping and handling. Furthermore, traditional testing equipment lacks precise real-time monitoring of stroke and torque when testing physical buttons and knobs, making it difficult to accurately detect subtle jamming issues in mechanical transmission. Additionally, appearance inspection is highly susceptible to interference from ambient light in the workshop, leading to inaccurate judgments of light brightness. Therefore, there is an urgent need to improve existing technologies to address the problems of low testing efficiency, poor functional integration, and susceptibility to external environmental interference in air conditioning control panel assembly testing. Summary of the Invention

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies of the existing technology and to provide an air conditioning control panel assembly testing device.

[0005] An air conditioner control panel assembly testing device includes a cabinet, on which a control system and a display component electrically connected to the control system are mounted, a first testing device, and a second testing device. The first testing device includes... The first test stand is used to fix the panel and form an electrical connection with the panel to detect the on / off state and electrical performance of the panel. A push-button assembly is used to press a panel button and to detect the pressing force and travel of the panel button. The second testing device includes a second testing platform, which is used to fix the panel and forms an electrical connection with the panel; A shape detection component is used to detect the integrity of the panel shape and the brightness of the panel buttons.

[0006] Furthermore, the first test stand includes a first mounting base, which is slidably mounted on a first guide rail via a chain drive component. The first mounting base is provided with a first pin that is electrically connected to the control system. The first pin is used to electrically connect to the panel and detect the on / off state and electrical performance of the panel through electrical signals.

[0007] Furthermore, the second test stand includes a second mounting base, which is slidably mounted on a second guide rail via a chain drive component. The second mounting base is provided with a second pin that is electrically connected to the control system, and the first pin is used to supply power to the panel.

[0008] Furthermore, locking components are provided on both sides of the first and second mounting bases. Each locking component includes a fixing base with a locking piece on it. The locking piece is used to limit the connection with both ends of the panel after the panel is installed in place.

[0009] Furthermore, the first testing device also includes a rotation component, which is used to rotate the panel knob and detect the torque of the panel knob. The rotation component includes a drive component and a torque sensor. The drive component is rotatably connected to a drive rod, and the drive rod is connected to a gripper. The gripper is used to engage with the panel knob to drive its rotation, thereby collecting torque data through the torque sensor and sending it to the control system.

[0010] Furthermore, the shape detection component includes a camera component and an image sensor. The camera component is used to collect shape information of the panel, and the image sensor is used to determine the integrity of the panel and the intensity of the button lights based on the shape information collected by the camera component.

[0011] Furthermore, the camera component is provided in two sets, located on the front and upper sides of the panel respectively, and the camera component includes a camera and a light mounted on the camera.

[0012] Furthermore, the shape detection component is located in a closed chamber, which includes an outer shell and a sliding door. The sliding door closes after the panel is moved into place under the control of the control system, thereby ensuring that the panel data being detected in the closed chamber is not affected by the external environment.

[0013] Furthermore, the cabinet is also equipped with a switch assembly electrically connected to the control system. The switch assembly includes a first switch electrically connected to the first testing device and a second switch electrically connected to the second testing device. There are two of each of the first and second switches, and both the first and second switches need to be pressed simultaneously when the first or second testing device is started.

[0014] Furthermore, the cabinet is also equipped with an emergency control component that is electrically connected to the control system. The emergency control component includes a key unlocking component and an automatic alarm component. The automatic alarm component is used to send a fault signal to the control system. The cabinet is also equipped with a sensor light grid component for detecting the position of a person's hand.

[0015] This invention offers significant advantages: by setting up a first testing device and a second testing device, multifunctional synchronous parallel testing is achieved. The first testing device integrates a first testing platform and a push-button assembly, which can simultaneously fix the panel and establish electrical connection continuity testing while using the push-button assembly to accurately quantify and measure the physical pressure and displacement of the button. The second testing device combines a second testing platform with a shape detection assembly, specifically for visual screening of image recognition, contour integrity, and light brightness. This dual-station independent yet interconnected layout completely changes the inefficient situation of multiple devices conducting separate testing and frequent manual transfers, significantly shortening the testing cycle of a single assembly and improving the efficiency of mass production testing on the assembly line.

[0016] Meanwhile, the combined design of the enclosed chamber and the two-way lighting camera assembly provides a constant and interference-free local optical environment for visual inspection, effectively eliminating the interference of stray light from the workshop on the button backlight intensity test, and significantly improving the accuracy of defect identification. Furthermore, the application of the two-hand linkage switch assembly and the sensor grating assembly constructs a dual safety barrier for operators, effectively eliminating the risk of mechanical injury due to accidental touches. The overall structure is scientifically designed and operates stably and reliably. Attached Figure Description

Detailed Implementation

[0024] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0026] The directional and positional terms used in this invention, such as "up," "down," "front," "back," "left," "right," "inner," "outer," "top," "bottom," and "side," are merely for reference to the accompanying drawings. Therefore, the directional and positional terms used are for illustrating and understanding this invention, and not for limiting the scope of protection of this invention.

[0027] This application provides an air conditioning control panel assembly testing device, such as... Figures 1 to 5 As shown: It includes a cabinet 1, on which a control system, a display component 3, a first testing device 4 and a second testing device 5 are installed.

[0028] The cabinet 1 serves as the mounting carrier for each testing component, forming an internal space for equipment installation. The control system can consist of an industrial controller, a testing module, and a data processing module, used to control the operation of each testing component and receive testing signals. The display component 3 is electrically connected to the control system 2 and is used to display parameter information and testing results during the testing process.

[0029] like Figure 1 and Figure 2As shown, the first testing device 4 includes a first testing platform 41 and a pressing component 42.

[0030] The first test bench 41 is used to fix the air conditioner control panel to be tested and to establish an electrical connection between the testing equipment and the panel. Specifically, the first test bench 41 can be set on a movable platform inside the cabinet 1, and the panel can be moved into the testing position. After the panel is installed on the first test bench 41, the control system 2 controls the first test bench 41 to start, so that the testing end contacts the corresponding connection position of the panel, thereby obtaining the testing signal of the internal circuit of the panel.

[0031] The push-button assembly 42 is positioned above or to the side of the first test platform 41 to simulate the action of manually pressing a panel button. In a specific implementation, the push-button assembly 42 may include a drive mechanism, a moving rod, and a pressure detection element. The drive mechanism pushes the moving rod to move, so that the end of the moving rod contacts the panel button and applies a pressing force. At the same time, the pressure detection element collects the change in the force applied to the button, and the position detection element collects the moving distance of the moving rod, thereby obtaining the button pressing force and pressing stroke data.

[0032] With the above structure, the first testing device 4 can complete electrical performance testing and button mechanical performance testing in a fixed panel state, reducing testing errors during manual operation.

[0033] The first test stand 41 includes a first mounting base 411, which is slidably mounted on a first guide rail 412 via a chain drive component 413. A first pin 414 is provided on the first mounting base 411.

[0034] The first guide rail 412 is fixedly installed inside the cabinet 1, the first mounting base 411 is used to support the panel to be tested, and the chain drive component 413 is connected to the control system 2 to drive the first mounting base 411 to move along the first guide rail 412. The chain drive component 413 may include a drive motor, a sprocket, and a transmission chain. The drive motor drives the sprocket to rotate, causing the chain to drive the first mounting base 411 to move.

[0035] The first pin 414 is electrically connected to the control system. When the panel is installed on the first mounting base 411, the first pin 414 contacts the corresponding interface of the panel, enabling the control system to detect the on / off state and electrical performance parameters of the panel through electrical signals.

[0036] In actual operation, the control system controls the chain drive component 413 to move the first mounting base 411 to the detection area. Then, the first pin 414 connects to the panel interface, the control system 2 inputs a detection signal to the panel, and judges the connection status of the panel circuit based on the return signal.

[0037] Optionally, in some embodiments, the first mounting base 411 may also be moved by a screw drive structure, with the screw driven by a motor to rotate, so that the mounting base moves along the guide rail direction.

[0038] Furthermore, such as Figure 4 As shown, the first testing device 4 also includes a rotating component 7, which is used to test the rotation performance of the panel knob.

[0039] The rotating assembly 7 includes a drive component 71, a torque sensor 72, a drive rod 73, and a gripper 74.

[0040] The drive component 71 is fixedly installed at the corresponding position of the first testing device 4. The output end of the drive component 71 is connected to the drive rod 73, which can rotate under the action of the drive component 71. The torque sensor 72 is disposed between the drive component 71 and the drive rod 73 to detect the torque change generated during the rotation of the knob.

[0041] The gripper 74 is located at the end of the drive rod 73. The gripper 74 is designed to fit the knob's external parts or the knob's connecting parts, according to the knob's structure. During testing, the gripper 74 connects to the knob, and the drive component 71 drives the drive rod 73 to rotate, thereby causing the knob to rotate synchronously. The torque sensor 72 collects the torque signal during the rotation process and sends it to the control system 2.

[0042] The above structure allows for the detection of the knob's rotation resistance and operating status.

[0043] As an alternative embodiment, those skilled in the art can also use a gear meshing structure, a friction wheel drive structure, or other methods to drive the knob to rotate, as long as the knob can be rotated and the rotational torque can be detected.

[0044] The second testing device 5 includes a second testing stand 51.

[0045] The second test stand 51 is used to fix the panel after the first stage of testing is completed and to form an electrical connection with the panel.

[0046] The second test stand 51 includes a second mounting base 511, which is slidably mounted on the second guide rail 512 via a chain drive component 413, and a second pin is provided on the second mounting base 511.

[0047] The second guide rail 512 is used to limit the movement direction of the second mounting base 511, and the chain drive component 413 drives the second mounting base 511 to move, so that the panel enters the second detection position. The second pin is electrically connected to the control system 2 and is used to supply power to the panel, so that the button indicator lights or display components on the panel are in working condition.

[0048] During the specific testing process, after the second pin is connected to the panel, the control system 2 supplies power to the panel, the panel button lights are activated, and then the appearance inspection process begins.

[0049] Optionally, in some embodiments, the second test station 51 may also share a moving mechanism with the first test station 41, and different detection functions may be achieved by switching detection modules.

[0050] Locking components 6 are provided on both sides of the first mounting base 411 and the second mounting base 511.

[0051] The locking assembly 6 includes a fixing base 61 and a locking piece 62.

[0052] The fixing base 61 is fixedly installed on the side of the mounting base, and the locking piece 62 is connected to the fixing base 61. When the panel is placed on the first mounting base 411 or the second mounting base 511, the locking piece 62 engages with the two ends of the panel to limit and fix the panel.

[0053] In practice, the locking piece 62 can adopt a rotating structure, which can be opened before the panel is placed and rotated to the locking position after the panel is installed to keep the panel stable.

[0054] By setting the locking component 6, panel movement during the detection process can be reduced, and the connection stability between the first pin 414, the second pin 513 and the panel interface can be improved.

[0055] As an alternative embodiment, those skilled in the art can also use structures such as elastic blocks or sliding buckles to achieve the panel fixing function.

[0056] The appearance detection component 8 is set at the corresponding position of the second testing device 5 and is used to detect the appearance status of the air conditioning control panel and the button display status.

[0057] The shape detection component 8 includes a camera component 81 and an image sensor.

[0058] The camera component 81 is used to collect image information of the outside of the panel. The image sensor is connected to the control system and is used to receive the image information collected by the camera component 81 and judge the integrity of the panel shape and the brightness of the buttons according to the preset detection program.

[0059] In practice, after the panel moves to the detection position via the second test bench 51, the control system activates the camera component 81 to acquire images of the panel surface. The acquired data is transmitted to the image sensor, which identifies the edge areas, button areas, and light-emitting areas on the panel. Based on the image information, it determines whether the panel has any defects such as shell damage, abnormal button installation, or abnormal light display.

[0060] The above structure allows for the use of visual inspection to detect the appearance of the panel, reducing the judgment differences caused by different viewing angles during manual observation.

[0061] As a specific implementation, the image sensor can establish multiple detection area models based on a preset detection area. For example, the panel can be divided into a shell detection area, a button detection area, and a display area. After the camera component 81 acquires images of the corresponding areas, the image sensor performs image comparison processing respectively to output the detection results.

[0062] The camera component 81 is provided in two sets, located on the front side and the top side of the panel respectively. The camera component 81 includes a camera 811 and a light 812 disposed on the camera 811.

[0063] The camera 811 located on the front of the panel is mainly used to capture information about the button area, display area, and surface structure of the front of the panel; the camera 811 located on the top of the panel is used to capture information about the top outline of the panel and some tilted areas. The two cameras 811 working together can acquire panel images from different angles.

[0064] The lighting lamp 812 is installed near the camera 811 to provide auxiliary light source to the detection area during the detection process, so that the camera 811 can obtain relatively stable image information.

[0065] In practice, the control system 2 can control different cameras 811 to start sequentially according to the detection process, and adjust the working status of the lighting lamps 812 when the detection environment changes, so as to keep the image acquisition process stable.

[0066] As an alternative embodiment, those skilled in the art can also add a side camera component 81 according to the panel structure, so that it can acquire panel images from multiple directions to meet the detection requirements of panels with different shapes.

[0067] The shape detection component 8 is located inside the enclosed chamber 9.

[0068] The enclosed chamber 9 includes an outer shell 91 and a sliding door 92.

[0069] The outer casing 91 encloses a testing space, within which the camera component 81 and a portion of the second test platform 51 are located. A sliding door 92 is mounted on the outer casing 91 and can be moved to open or close under the control of the control system.

[0070] When the second test stand 51 moves the panel to the detection position, the control system 2 controls the sliding door 92 to close, so that the panel is in a relatively closed detection environment, and then the camera component 81 is activated to acquire images.

[0071] By setting up a closed chamber 9, the impact of changes in external light on the visual inspection process can be reduced.

[0072] In practice, the sliding door 92 can be moved by a motor-driven rack and pinion mechanism, or it can be opened and closed by a synchronous belt drive.

[0073] As an alternative embodiment, those skilled in the art can also use a flip-door structure or a lifting door structure to form a closed testing space.

[0074] Furthermore, such as Figure 1 As shown, a switch assembly 10 is also installed inside the cabinet 1.

[0075] The switch assembly 10 includes a first switch 101 and a second switch 102.

[0076] The first switch 101 is electrically connected to the first test device 4 and is used to control the start of the first test device 4; the second switch 102 is electrically connected to the second test device 5 and is used to control the start of the second test device 5.

[0077] Two first switches 101 and two second switches 102 are provided. The control system 2 will only control the first test device 4 to run after both first switches 101 are pressed at the same time; the control system 2 will only control the second test device 5 to run after both second switches 102 are pressed at the same time.

[0078] In practice, the two switches can be set in positions that the operator can reach with both hands at the same time. When the operator needs to start the detection action, the two corresponding switches need to be operated at the same time.

[0079] This structure can prevent the testing mechanism from suddenly operating due to accidental activation of a single switch, or for a person to accidentally put their other hand into the testing equipment, thus affecting the testing process and test data.

[0080] As an alternative embodiment, those skilled in the art can also use a touch-screen dual-confirmation control method or a foot-operated start structure to achieve the same control function.

[0081] Emergency control components 11 are also installed inside cabinet 1.

[0082] The emergency control component 11 includes a key unlocking component 111 and an automatic alarm component.

[0083] The key unlocking component 111 is used to manage the control permissions of the device. When the device needs maintenance or adjustment, the device can be put into the corresponding control state by key operation.

[0084] The automatic alarm component is connected to the control system and is used to receive fault signals sent by the control system 2 when the equipment is malfunctioning, and to output alarm information.

[0085] The cabinet 1 is also equipped with a sensor light grid assembly 12.

[0086] The light sensor assembly 12 is used to detect whether a person's hand has entered the detection area of ​​the equipment. When a person is detected entering a dangerous area during the detection process, the light sensor assembly 12 sends a detection signal to the control system, and the control system stops the corresponding detection action based on the signal.

[0087] In practice, the sensor grating assembly 12 can be set at the operation opening of the cabinet 1, forming a detection area through the transmitter and receiver. When an object enters the detection area and blocks the light, the control system judges it as an abnormal state.

[0088] As an alternative embodiment, those skilled in the art can also use safety door switches, area sensors, or other methods to achieve personnel protection detection functions.

[0089] In use, the air conditioner control panel to be tested is first installed on the first test bench 41, and the panel is fixed in place by the locking component 6. The control system controls the first test bench 41 to move to the testing position, so that the first pin 414 is connected to the panel interface, and the on / off state and electrical performance of the internal circuit of the panel are detected by electrical signals.

[0090] Subsequently, the control system controls the operation of the push assembly 42, which drives the detection end to press the panel button through the drive structure, and simultaneously collects the pressure and movement distance data of the button. When the panel has a knob structure, the gripper 74 in the rotation assembly 7 is connected to the knob, the drive component 71 drives the knob to rotate, the torque sensor 72 collects the torque change during the knob rotation process, and sends the detection data to the control system.

[0091] After the first stage of testing is completed, the panel is transferred to the second test bench 51. The second pin 513 supplies power to the panel, activating the button indicator lights and other display components. The control system 2 controls the second test bench 51 to move into the enclosed chamber 9 and closes the sliding door 92. The camera component 81 acquires image information from the panel, and the image sensor 82 determines the integrity of the panel's shape and the brightness of the buttons based on the image information.

[0092] Throughout the testing process, display component 3 is used to display the testing status and results, switch component 10 is used to control the start of the testing, and emergency control component 11 is used to control the equipment and trigger alarms in abnormal conditions, thereby completing the comprehensive testing of the air conditioning control panel assembly.

[0093] The above description discloses only preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, equivalent variations made in accordance with the claims of the present invention are still within the scope of the present invention.

[0094] While the invention has been described with reference to several specific embodiments, it should be understood that the invention is not limited to the disclosed specific embodiments. The invention is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
