Description

Technical Field

[0001] This utility model relates to the field of testing equipment technology, and in particular to a controller testing device equipped with a high-frequency receiving module. Background Technology

[0002] A controller equipped with a high-frequency receiver module is an embedded control system that integrates a radio frequency (RF) high-frequency receiver module. Its core function is to receive, demodulate, and decode wireless high-frequency signals (such as 315MHz / 433MHz / 2.4GHz) and execute corresponding control commands. The controller is the core of wireless control, enabling long-distance, low-power, and stable wireless communication through the high-frequency receiver module. It is widely used in smart homes, industry, automobiles, security, and other fields.

[0003] In existing technologies, when performing performance testing on a controller, it is placed inside a shielded enclosure. The shielded enclosure serves as a carrier for the controller under test and is designed to shield against external high-frequency electromagnetic interference. The existing shielded enclosure includes a body, a top cover, and a lifting device tilted between the body and the top cover. One side of the body and the top cover is rotatably connected by a hinge, allowing the top cover to rotate around this side to open or close the shielded enclosure. The body and the top cover are connected to opposite ends of the lifting device. The lifting device drives the top cover to rotate around the hinge, moving it closer to or away from the body, thus opening or closing the enclosure. The enclosure contains a clamp, which includes a carrier platform for loading the product under test, a first drive cylinder for driving the carrier platform vertically, and a second drive cylinder for driving the carrier platform horizontally, enabling the feeding and discharging of the product under test.

[0004] The aforementioned shielding box only has one loading platform, which can only test one type of product and cannot test products with different structures, thus its practicality is low. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art by providing a controller testing device equipped with a high-frequency receiving module. It is equipped with at least two sets of fixtures to test controllers with different structures, and is highly practical. The installation fixtures are selected according to the controller being tested.

[0006] The technical solution of this utility model is as follows: A controller testing device with a high-frequency receiving module includes an electrical control box and a shielding box disposed on the electrical control box. The shielding box includes a lower cover and an upper cover. One side of the upper cover is rotatably connected to the lower cover by a hinge, so that the upper cover rotates around one side of the lower cover to open or close. A lifting device is connected between the upper cover and the lower cover. The lifting device drives the upper cover to rotate around the hinge to move closer to or away from the lower cover, thereby realizing the opening and closing of the shielding box. The electrical control box is provided with an on / off switch and a control button for driving the lifting device. The lower cover is provided with a loading plate and a first driving component for driving the loading plate to slide horizontally within the shielding box. The loading plate is provided with a detachable first loading clamp or a second loading clamp. Both loading clamps include a tray and several positioning blocks disposed on the tray. The tray and the loading plate are detachably connected, and a positioning area is formed between each positioning block for the controller under test to be placed.

[0007] By adopting the above technical solution, and by setting replaceable first and second loading fixtures on the loading plate, compatible testing of controllers under test of different models and structures is achieved, avoiding the need for complete equipment replacement, greatly improving the equipment's versatility and adaptability, and reducing the equipment cost for multi-variety testing. The shielding box adopts a hinged opening and closing structure, which, together with the lifting device and the control buttons on the electrical control box, realizes the automatic opening and closing of the shielding box, replacing the traditional manual opening method. This makes operation convenient and labor-saving, while ensuring the rapid establishment of the shielding environment required for high-frequency testing. The positioning blocks on the tray form a positioning area, allowing the controller under test to be quickly placed and positioned, simplifying the clamping process, significantly improving the testing cycle time, and making it suitable for mass production testing scenarios.

[0008] A further feature of this invention is that the first loading fixture also includes a needle block mounting base, which is mounted on the loading plate. The needle block mounting base is provided with a first connector and a first probe block. The first probe block is provided with a plurality of first probes that contact the test points of the controller under test.

[0009] With the above-mentioned further configuration, the first loading fixture is equipped with a pin block mounting base and a first probe block, providing a dedicated probe contact interface for a specific model of controller under test, ensuring accurate alignment of the test point and the probe, effectively reducing the risk of poor contact. When the first driving component drives the loading plate to slide horizontally, the test point on the controller under test contacts and conducts with the first probe of the first probe block; the probe signal is centrally extracted through the first connector, providing a stable and low-loss signal transmission path for the high-frequency receiving module, reducing signal interference, and ensuring the accuracy and reliability of high-frequency signal testing.

[0010] A further feature of this invention is that the second loading fixture also includes a second connector and a second probe block mounted on a tray, the second probe block having a plurality of second probes that contact the test points of the controller under test.

[0011] By adopting the above-mentioned further settings, and by setting an independent second loading fixture, the device can be compatible with another model of controller under test, realizing the function of testing multiple products with one device, avoiding repeated investment in equipment, and improving equipment utilization. The second connector and the second probe block form an independent signal acquisition path, which can be individually adapted to the pin definitions and signal characteristics of different controller models, avoiding signal crosstalk between different products, and improving the versatility and stability of the test.

[0012] A further improvement of this invention is that each positioning block corresponds to one of the four corners of the controller under test, and a boss is provided on the inner side wall of the positioning block, on which the controller under test is mounted.

[0013] With the above-mentioned further design, the boss structure on the inner wall of the positioning block provides a stable support surface for the controller under test, avoiding scratches or wear caused by direct contact between the bottom surface of the controller and the tray, thus protecting the product's appearance. The boss structure ensures that the controller is only subjected to force at its four corners, with the sides completely open, facilitating quick handling by manual or robotic arms. At the same time, it forms a stable positioning reference, preventing horizontal displacement of the controller during the testing process and improving positioning accuracy.

[0014] A further feature of this invention is that the tray is provided with a positioning post for positioning the controller under test. When the controller under test is placed in the positioning area, the controller under test is snapped onto the positioning post.

[0015] With the above-mentioned further configuration, the positioning pins on the tray can cooperate with the corresponding holes on the controller under test to achieve foolproof snap-fit ​​positioning, effectively preventing the controller from being placed backwards or off-center, ensuring the accurate alignment of the probe and the test point, and avoiding test failure caused by mis-contact or contact deviation; the positioning pins and positioning blocks work together to form a dual positioning constraint, effectively limiting the horizontal and vertical displacement of the controller, preventing the controller from shifting due to vibration or pressure plate during the test, and improving the stability and consistency of the test.

[0016] A further feature of this invention is that the bottom of the tray is provided with a magnet, and the loading plate is provided with a magnetic induction device. When the tray is assembled on the loading plate, the magnet and the magnetic induction device are arranged in a corresponding manner.

[0017] With the above-mentioned further configuration, the magnet at the bottom of the tray cooperates with the magnetic induction on the loading plate to achieve rapid adsorption and positioning of the tray, eliminating the need for complex alignment actions, making loading and unloading convenient, and greatly improving the efficiency of fixture replacement; the magnetic attraction force can make the tray fit tightly with the loading plate, preventing the tray from moving during sliding or testing, ensuring the stability of the fixture installation, and indirectly improving the reliability of probe contact.

[0018] A further feature of this invention is that a pressure plate assembly is provided on the inner top wall of the upper cover. The pressure plate assembly includes a fixed plate, a pressure plate, and a second driving member that drives the pressure plate to move up and down. The fixed plate is detachably installed on the inner top wall of the upper cover. The second driving member is fixedly installed on the fixed plate. The pressure plate is directly or indirectly installed on the output shaft of the second driving member. When the upper cover is closed, the pressure plate is pressed onto the controller under test by the action of the second driving member.

[0019] With the above-mentioned further configuration, after the top cover is closed, the second cylinder operates, driving the pressure plate to move downwards. The pressure plate presses onto the upper surface of the controller under test, providing comprehensive positioning of the controller and preventing displacement from affecting the test. It also prevents poor probe contact caused by controller warping or gaps, ensuring stable contact at all test points. The pressure plate assembly can be adapted and adjusted according to the thickness and size of different controllers under test, and the pressure can be adjusted through the second drive component, avoiding hard contact that could damage the controller and improving compatibility with different products.

[0020] A further feature of this invention is that the tray is assembled onto the loading plate with screws, the loading plate is provided with four guide posts, and the tray is provided with corresponding guide holes. When the tray is installed with the loading plate, the guide posts are located in the guide holes, and guide sleeves are also provided in the guide holes.

[0021] By adopting the above-mentioned further settings, the tray is installed and positioned for quick installation, which also facilitates subsequent screw assembly. This ensures the consistency of the probe and test point positions after fixture replacement, eliminating the need for repeated calibration. The guide sleeve design prevents wear between the guide post and the guide hole.

[0022] A further feature of this invention is as follows: the shielding box is provided with a base plate and two support seats on the base plate. The first driving member is located between the two support seats. The output shaft of the first driving member is directly or indirectly connected to the loading plate. Both support seats are provided with slide rails. The loading plate is provided with a slider. The slider is guided and slidably cooperated with the slide rails.

[0023] Further design: Both support bases are equipped with stops at both ends of the slide rail to limit the movement of the slider.

[0024] By adopting the above-mentioned further settings, the sliding of the slider and the guide rail makes the structure stable when the loading plate slides, avoiding displacement of the controller under test on the fixture, which would affect the detection effect. When the first driving component drives the loading plate to slide, the stop can activate the limiting function to prevent the slider from sliding too far and detaching from the guide rail, causing the loading fixture to deviate and affecting the detection. After the slider contacts the stop, the slider can no longer slide and can only slide in the opposite direction. Attached Figure Description

[0039] like Figure 1-9As shown, a controller testing device equipped with a high-frequency receiving module includes an electrical control box 1 and a shielding box 2 mounted on the electrical control box 1. The shielding box 2 includes a lower cover 22 and an upper cover 21. One side of the upper cover 21 is rotatably connected to the lower cover 22 via a hinge 23, allowing the upper cover 21 to rotate around one side of the lower cover 22 to open or close. A lifting device 3 is connected between the upper cover 21 and the lower cover 22. The lifting device 3 drives the upper cover 21 to rotate around the hinge 23, moving it closer to or away from the lower cover 22, thereby opening and closing the shielding box 2. The lifting device 3 is equipped with a cylinder. Cylinders are located on both sides of the shielding box 2. The cylinder bodies are mounted on the lower cover 22, and the output shafts of the cylinders are connected to the upper cover 21. The electrical control box 1 is equipped with an on / off switch 11 and a control button 12 for driving the lifting device 3. The lower cover 22 contains a loading plate 4 and a first driving component 5 that drives the loading plate 4 to slide horizontally within the shielding box 2. The first driving component 5 and the second driving component 93 can be cylinders, electric cylinders, or motors, etc. In this invention, cylinders are preferred. The loading plate 4... The loading plate 4 is equipped with a detachable first loading fixture 6 or a second loading fixture 7. Both fixtures include a tray 101 and several positioning blocks 102 on the tray 101. The tray 101 is detachably connected to the loading plate 4. Positioning blocks 102 form a positioning area 103 for the controller under test (DUT) to be placed into. By providing replaceable first and second loading fixtures 7 on the loading plate 4, compatible testing of DUTs of different models and structures is achieved, avoiding the need for complete equipment replacement. This significantly improves the equipment's versatility and adaptability, and reduces costs. The equipment cost for multi-variety testing; the shielding box 2 adopts a hinge 23 type opening and closing structure, which, together with the lifting device 3 and the control button 12 on the electrical control box 1, realizes the automatic opening and closing of the shielding box 2, replacing the traditional manual opening method, which is convenient and labor-saving. At the same time, it ensures the rapid establishment of the shielding environment required for high-frequency testing. The positioning block 102 on the tray 101 forms a positioning area 103, and the controller under test can be quickly placed and positioned, which simplifies the clamping process, significantly improves the test cycle, and is suitable for mass production testing scenarios. The rear wall of the electrical control box 1 is equipped with an AC power interface with fuse, a control interface and a gas valve module. The electrical control box 1 is equipped with a circuit board. The AC power interface is connected to 220V mains power through the power cord to directly power the electrical control box 1. The control interface is connected to an external host computer or PLC through a serial cable. The signal cable is connected to the electrical control box 1. The rear wall of the shielding box 2 is equipped with a through-wall signal interface and a pneumatic connector.The through-wall signal interface has a male connector on the outside and a female connector on the inside, enabling signal transmission through the wall of the shielded box 2. Both are fixed by a flange on the box wall, allowing high-frequency / detection signals to penetrate both inside and outside while ensuring the electromagnetic seal of the shielded box 2. An external air source is connected to a pneumatic connector, controlled by a manual valve module, and connected to a cylinder via an air pipe to drive the mechanism. The female connector can be directly plugged into the connector of the first loading clamp 6 or the second loading clamp 7 via a cable / ribbon cable, introducing high-frequency / electrical signals from outside the box into the box in one go.

[0040] The testing device of this utility model can fix two controllers with different structures. The first loading fixture 6 fixes the long strip controller 200 and puts the long strip controller 200 into the positioning area 103 on the first loading fixture 6. The second loading fixture 7 fixes the rectangular controller 300 and puts the rectangular controller 300 into the positioning area 103 on the second loading fixture 7 from top to bottom. The long strip controller and the rectangular controller cannot be placed in the testing device at the same time for testing, but can only be placed separately. The high-frequency antenna extends from the side wall of the testing device into the inside of the testing device (not shown in the figure) and transmits the high-frequency signal to the controller under test.

[0041] Specifically, the first loading fixture 6 further includes a pin block mounting base 61, which is mounted on the loading plate. The pin block mounting base 61 is provided with a first connector 611 and a first probe block 612. The first probe block 612 is provided with a plurality of first probes that contact the test points of the controller under test. The addition of the pin block mounting base 61 and the first probe block 612 to the first loading fixture 6 provides a dedicated probe contact interface for a specific model of controller under test, ensuring accurate alignment of the test points and probes and effectively reducing the risk of poor contact. When the first driving component 5 drives the loading plate 4 to slide horizontally, the test points on the controller under test contact and conduct with the first probes of the first probe block 612. The probe signal is centrally extracted through the first connector 611, providing a stable and low-loss signal transmission path for the high-frequency receiving module, reducing signal interference, and ensuring the accuracy and reliability of high-frequency signal testing.

[0042] Specifically, the second loading fixture 7 also includes a second connector 71 and a second probe block 72 mounted on the tray 101. The second probe block 72 is provided with several second probes that contact the test points of the controller under test. By setting up an independent second loading fixture 7, the device can be compatible with another model of controller under test, realizing the function of testing multiple products with one device, avoiding repeated equipment investment and improving equipment utilization. The second connector 71 and the second probe block 72 form an independent signal acquisition path, which can be individually adapted to the pin definitions and signal characteristics of different models of controllers, avoiding signal crosstalk between different products and improving the universality and stability of the test.

[0043] Each positioning block 102 corresponds to one of the four corners of the controller under test. The inner wall of the positioning block 102 is provided with a boss 1021. The controller under test is mounted on the boss 1021. The boss 1021 structure on the inner wall of the positioning block 102 provides a stable support surface for the controller under test, avoiding scratches or wear caused by direct contact between the bottom surface of the controller and the tray 101, thus protecting the appearance of the product. The boss 1021 structure ensures that the controller is only subjected to force at the four corners, and the sides are completely open, which facilitates quick picking and placing by manual or robotic arms. At the same time, it forms a stable positioning reference, preventing the controller from undergoing horizontal displacement during the testing process and improving the positioning accuracy.

[0044] The tray 101 is equipped with positioning posts 1011 for positioning the controller under test (DUT). When the DUT is placed in the positioning area 103, it snaps into the positioning posts 1011. The positioning posts 1011 on the tray 101 can mate with corresponding holes on the DUT to achieve foolproof snap-in positioning, effectively preventing the controller from being placed backwards or off-center, ensuring accurate alignment of the probe and test point, and avoiding test failure caused by mis-contact or contact deviation. The positioning posts 1011 and the positioning block 102 work together to form a double positioning constraint, effectively limiting the horizontal and vertical displacement of the controller, preventing the controller from shifting due to vibration or pressure from the pressure plate 92 during the testing process, and improving accuracy. This improves the stability and consistency of the test. The tray 101 is assembled onto the loading plate 4 by screws 8, making the loading fixture and the loading plate 4 detachable. The loading plate 4 is provided with four guide posts 41, and the tray 101 is provided with corresponding guide holes 1012. When the tray 101 and the loading plate 4 are installed, the guide posts 41 are located in the guide holes 1012. The guide holes 1012 are also provided with guide sleeves to position the tray 101 for quick installation and facilitate subsequent screw assembly. This ensures the consistency of the probe and test point positions after fixture replacement, eliminating the need for repeated calibration. The guide sleeves prevent wear between the guide posts 41 and the guide holes 1012.

[0045] The bottom of the tray 101 is provided with a magnet 1013, and the loading plate 4 is provided with a magnetic induction device 42. When the tray 101 is assembled on the loading plate 4, the magnet 1013 and the magnetic induction device 42 are correspondingly arranged. The magnet 1013 at the bottom of the tray 101 cooperates with the magnetic induction device 42 on the loading plate 4 to achieve rapid adsorption and positioning of the tray 101 without complicated alignment actions, making loading and unloading convenient and greatly improving the efficiency of fixture replacement. The adsorption force of the magnet 1013 can make the tray 101 fit tightly with the loading plate 4, preventing the tray 101 from moving during sliding or detection, ensuring the stability of the fixture installation, and indirectly improving the reliability of probe contact.

[0046] The inner top wall of the upper cover 21 is provided with a pressure plate assembly 9. The pressure plate assembly 9 includes a fixed plate 91, a pressure plate 92, and a second driving member 93 that drives the pressure plate 92 to move up and down. The fixed plate 91 is detachably installed on the inner top wall of the upper cover 21. The second driving member 93 is fixedly installed on the fixed plate 91. The pressure plate 92 is directly or indirectly installed on the output shaft of the second driving member 93. When the upper cover 21 is closed, the pressure plate 92 is pressed onto the controller under test under the action of the second driving member 93. After the upper cover 21 is closed, the second cylinder works and drives the pressure plate 92 to move down. The pressure plate 92 is pressed onto the upper end face of the controller under test, which provides comprehensive positioning of the controller under test, avoids displacement affecting the test, and also prevents poor probe contact caused by controller warping or gaps. It ensures stable contact of all test points. The pressure plate assembly 9 can be adapted and adjusted according to the thickness and size of different controllers under test. The pressure can be adjusted by the second driving member 93, avoiding hard contact that could damage the controller and improving compatibility with different products.

[0047] The shielding box 2 contains a base plate 24 and two support seats 25 mounted on the base plate 24. The first driving member 5 is located between the two support seats 25, and its output shaft is directly or indirectly connected to the loading plate 4. Each support seat 25 is equipped with a slide rail 251, and the loading plate 4 is equipped with a slider 43. The slider 43 is guided and slidably engaged with the slide rail 251. Each support seat 25 has a stop block 252 at both ends of the slide rail 251 to limit the slider 43. Through the guided sliding engagement of the slider 43 and the slide rail 251, the loading plate 4 remains structurally stable during sliding, preventing displacement of the controller under test on the fixture and affecting the detection effect. When the first driving member 5 drives the loading plate 4 to slide, the stop block 252 can activate its limiting function to prevent the slider 43 from sliding over-prone. If the slider detaches from the guide rail, the loading fixture will deviate, affecting the detection. After the slider 43 contacts the stop 252, the slider 43 can no longer slide and can only slide in the opposite direction. The bottom of the shielding box 2 is equipped with a bakelite board, and the base plate 24 is mounted on the circuit board. Since the shielding box 2 is generally made of metal, the bakelite board has high insulation strength and is used to isolate the live parts from the metal frame to ensure accurate detection signals and prevent misjudgments. The controller has a high-frequency receiving module that is sensitive to electromagnetic interference. The bakelite board is non-conductive and non-magnetic, and will not reflect, absorb or interfere with high-frequency signals like metal. It can reduce noise interference and improve detection stability. During the test, instantaneous arcing, overcurrent and heat may occur. The bakelite board is heat-resistant, arc-resistant and not easily combustible, which can prevent instantaneous arcing of the probe from damaging the equipment or controller and improve safety.

[0048] At least one shielding groove 221 is provided adjacent to each other along the length direction on the mating surface of the lower cover 22 that fits with the upper cover 21. A shielding protrusion 211, matching each shielding groove 221, is provided adjacent to each other along the length direction on the mating surface of the upper cover 21 that fits with the lower cover 22. The height of the shielding protrusion 211 is equal to or less than the depth of the shielding groove 221, ensuring close contact between the shielding groove 221 and the shielding protrusion 211. Preferably, the lower cover 22 has one shielding groove 221, which is arranged circumferentially around the lower cover 22. The upper cover 21 has one shielding protrusion 211 corresponding to the shielding groove 221, ensuring an effective shielding space is achieved when the upper cover 21 and the lower cover 22 are fastened together.

[0049] Handles 13 are provided on both sides of the electrical control box 1 or the lower cover 22 for easy handling. The electrical control box 1 contains a circuit board, and the control button 12 is electrically connected to the circuit board. The control button 12 includes two green closing buttons and a red opening button. The two closing buttons are arranged parallel to each other at a certain distance. When the shielding box 2 is in the open state, if it is necessary to close the shielding box 2 for testing, both closing buttons must be pressed simultaneously with both hands to send a control signal to close the shielding box 2, causing the upper cover 21 to rotate and press down to close with the lower cover 22, which has a certain anti-pinch function. Specifically, pressing the two green closing buttons simultaneously will cause the two double-acting cylinders to be pneumatically driven to rotate and press down on the upper cover 21, and the upper cover 21 will close in the two double-acting cylinders. The opening button is located between the two closing buttons. When it is necessary to open the shielding box 2 in the closed state, press the red opening button to cause the upper cover 21 to press down and rotate to separate from the lower cover 22, thus opening the shielding box 2.
