Description

Technical Field

[0001] This utility model relates to the field of electronic product testing equipment technology, specifically to a test fixture for remote control testing equipment, and in particular a modular test fixture that integrates remote control positioning, electrical signal acquisition, and physical marker execution functions. Background Technology

[0002] During the remote control manufacturing process, multiple functional tests are required on the assembled remote control PCBA board and the complete device. These tests include parameter detection of components such as resistors, capacitors, and inductors on the circuit board, program programming, and static current testing. After testing, qualified products must be physically marked to enable product quality traceability. Traditionally, these testing and marking processes are performed by multiple independent workstations, which has the following shortcomings:

[0003] First, the separate workstations result in low production efficiency and a lack of unified data traceability. Component parameter testing, program programming, current testing, and marking are performed on different equipment or workstations, requiring products to be moved and transported between these workstations, which is cumbersome and slows down the production cycle. Each workstation operates independently, and test data is stored in a scattered manner, making unified quality analysis and full-process data traceability impossible.

[0004] Secondly, the positioning accuracy and contact reliability of the test fixtures are insufficient. Existing test fixtures typically use a fixed pin plate structure, where the remote control under test is placed and then directly pressed down for contact. Due to the dimensional tolerances of remote control products, improper control of the pressing stroke during the pressing process can easily lead to poor contact between the probe and the test point or over-pressure of the probe, damaging the PCBA board and affecting test accuracy and product yield.

[0005] Third, the integration of the shielded testing environment and the fixture structure needs to be improved. Remote control testing needs to be conducted in an environment shielded from external electromagnetic interference. In existing solutions, the shielding box and the internal fixture are usually designed separately, resulting in an overall structure that is not compact enough. Furthermore, the opening and closing of the shielding box and the pressing action of the fixture are mostly controlled independently, leading to low integration and automation.

[0006] Fourth, it lacks an instant marking function after testing. In traditional solutions, after the product passes the test, it needs to be moved to a separate grinding or marking station for marking. This not only increases the number of processes but may also lead to marking errors due to mixing of materials during the process.

[0007] Therefore, how to provide a test fixture that is highly integrated, accurately positioned, reliably contacted, and capable of simultaneously completing testing and marking has become a technical problem that urgently needs to be solved in this field. Utility Model Content

[0008] In view of the technical problems in the existing technology, such as the separation of multiple workstations in remote control testing, insufficient positioning accuracy and contact reliability of test fixtures, low integration of shielding environment and fixtures, and disconnect between testing and marking, this utility model aims to provide a test fixture for remote control testing equipment, which realizes the integration of remote control floating positioning, precise contact conduction and test marking, thereby improving testing efficiency and reliability.

[0009] To achieve the above objectives, the present invention provides the following technical solution:

[0010] A test fixture for a remote control testing device includes:

[0011] The shielding housing has a test chamber inside. The shielding housing includes a base part and a cover part. The cover part is movably connected to the base part and is driven to open or close by an opening and closing drive.

[0012] The support assembly is located inside the base. The support assembly includes a base plate, a detection base plate located above the base plate, and a support plate located above the detection base plate. The support plate is provided with a positioning area for placing the remote controller under test. The detection base plate is provided with multiple signal acquisition terminals. The support plate is provided with clearance holes for the signal acquisition terminals to pass through at the corresponding positions.

[0013] The carrier plate is supported on the base plate or detection base plate by an elastic reset member, so that the carrier plate can float downward when the remote control under test is pressed, until the remote control under test makes contact with the signal acquisition terminal and conducts.

[0014] The pressure-reducing component is located above the support component. The pressure-reducing component is connected to a linear drive device and moves downward under its drive to apply downward pressure to the remote control under test on the support plate.

[0015] By adopting the above technical solution, the shielding shell, the support component, and the pressure-blocking component are integrated into a single test fixture. The shielding shell directly serves as the external structure of the test fixture, while the support and pressure-blocking components are integrated internally, resulting in a compact overall structure. The support plate is floatingly supported on the base plate or detection base plate via an elastic reset component. When the pressure-blocking component applies downward pressure to the remote control under test (DUT) placed on the support plate, the support plate is compressed and floats downward, causing the DUT to gradually approach the signal acquisition terminal on the detection base plate until the two make contact and conduct. This floating support structure effectively absorbs the dimensional tolerances of the DUT, avoiding problems such as poor contact of the signal acquisition terminal or damage to the remote control due to improper control of the downward pressure stroke, thus ensuring the consistency and reliability of signal acquisition. Simultaneously, the cover of the shielding shell is automatically opened or closed by an opening / closing drive component, coordinating with the pressing action of the internal pressure-blocking component to automate the testing process and improve testing efficiency.

[0016] Preferably, the detection substrate is provided with an upwardly extending guide positioning member, which passes through the carrier plate and through the positioning hole on the remote controller under test to assist in positioning the remote controller under test.

[0017] By adopting the above technical solution, the guide positioning component plays a guiding role during the placement of the remote control under test, ensuring that the remote control is placed in the correct position and orientation within the positioning area, preventing the remote control from tilting or misaligning. During the testing process, the guide positioning component penetrates the positioning hole of the remote control, constraining the horizontal displacement of the remote control and ensuring that the test point of the remote control is precisely aligned with the signal acquisition terminal in the horizontal direction, thereby improving the repeatability and contact reliability of the test.

[0018] Preferably, the support plate is provided with multiple limiting members, which are arranged circumferentially and used to form a positioning area on the support plate.

[0019] By adopting the above technical solution, the remote control under test is placed within the space defined by the limiting component. The limiting component provides horizontal limitation and coarse positioning for the outer periphery of the remote control, enabling it to be placed quickly and accurately in the predetermined position. The circumferential limiting component, in conjunction with the guiding positioning component, forms a multi-layered positioning system combining coarse and fine positioning, further improving the accuracy and consistency of remote control placement.

[0020] Preferably, the detection substrate is provided with a limiting structure to limit the maximum downward movement of the carrier plate when the carrier plate floats downward. When the carrier plate abuts against the limiting structure, the remote controller under test and the signal acquisition terminal are in contact and conducting state.

[0021] By adopting the above technical solution, when the carrier plate is compressed and moves downward to abut against the limiting structure, the remote control under test and the signal acquisition terminal are exactly in the contact and conduction state required by the design. The limiting structure provides a rigid end point for the downward movement of the carrier plate, ensuring the consistency of the stroke of each downward press, preventing damage to the signal acquisition terminal due to excessive force caused by excessive pressing, and also preventing insufficient contact due to insufficient pressing, thus ensuring the stability and reliability of signal acquisition.

[0022] Preferably, the pressing component includes an upper fixing plate and an upper pressing base plate. The upper pressing base plate is fixed below the upper fixing plate. The upper pressing base plate is provided with at least one physical mark actuator and / or multiple pressing elements. The physical mark actuator and / or pressing elements extend downward and press against the upper surface of the remote controller under the drive of the linear drive device.

[0023] By adopting the above technical solution, the pressure-reducing assembly employs a double-layer structure consisting of an upper fixing plate and an upper pressure-reducing substrate. A physical marking actuator and / or a pressure-applying component are integrated onto the upper pressure-reducing substrate. The physical marking actuator can directly apply physical markings (such as grinding marks) to the surface of the remote control under test after testing, while the pressure-applying component evenly transmits the pressure to the upper surface of the remote control. This integrated design allows testing and marking to be completed simultaneously at the same station, eliminating the need to transfer the remote control to a separate marking station. This eliminates the risk of material mixing and wasted time caused by process flow, improving production efficiency and the reliability of product quality traceability.

[0024] Preferably, the lower end of the physical marker actuator is flush with the lower end face of the pressure-applying component, and simultaneously contacts the upper surface of the remote controller under test under the drive of the linear drive device.

[0025] By adopting the above technical solution, the pressure-applying component provides uniform clamping force to the remote control, ensuring stable contact at each test point. The physical marking actuator arrives at the remote control surface synchronously with the pressure-applying component, completing the marking during the pressing process. The coordinated actions ensure both the stability of the test contact and the accuracy of the marking position and the reliability of the marking action. The synchronization of the marking and pressing actions also avoids deviations that may occur during secondary positioning.

[0026] Preferably, the upper fixing plate is provided with a through clearance groove, the physical marking actuator is installed in the through clearance groove, the physical marking actuator extends downward to the lower part of the upper pressing base plate, and the pressure applying element is provided on the side of the physical marking actuator.

[0027] By adopting the above technical solution, the through-cut groove provides installation space for the physical marker actuator, allowing the main body of the physical marker actuator to be embedded inside the upper fixing plate without occupying too much space above the upper pressure plate, resulting in a more compact overall structure. The pressure-applying component is located on the side of the physical marker actuator, forming a spatially complementary layout with the physical marker actuator. The two are rationally arranged within a limited cross-section, without interfering with each other.

[0028] Preferably, the carrier assembly further includes a guide shaft and a bushing. The bushing is fixed to the detection substrate, the upper end of the guide shaft is fixed to the carrier plate, and the lower end of the guide shaft passes through the bushing and the detection substrate. The carrier plate floats vertically through the cooperation of the guide shaft and the bushing.

[0029] By adopting the above technical solution, when the carrier plate floats downward under the action of the elastic reset component, the guide shaft slides along the axial direction of the bushing, providing precise linear guidance for the floating movement of the carrier plate. The cooperation between the guide shaft and the bushing ensures that the carrier plate maintains a horizontal posture throughout the floating process, without tilting or shifting, thereby ensuring uniform contact between each test point on the remote control under test and the signal acquisition terminal, improving the consistency and accuracy of the test.

[0030] Preferably, the rear end of the cover portion is hinged to the rear end of the base portion, and the opening and closing drive member is connected between the cover portion and the base portion; the cover surface between the cover portion and the base portion is a contact slope that slopes upward from the front to the back.

[0031] By adopting the above technical solution, the rear end of the cover is hinged to the rear end of the base. An opening / closing drive is connected between the cover and the base, driving the cover to rotate around the hinge axis to open or close. The contact surface between the cover and the base adopts a contact slope design that slopes upwards from the front to the back, increasing the contact area and shielding sealing effect, effectively blocking interference from external high-frequency electromagnetic waves to the test signal. Simultaneously, this slope design makes the front area of ​​the cover larger than the back area, providing the operator with a better field of view from the front, and resulting in a more harmonious and aesthetically pleasing appearance.

[0032] Preferably, a guide rod is also connected between the pressing component and the support plate to guide the movement of the pressing component when it moves downward.

[0033] By adopting the above technical solution, a guide rod is connected between the pressing component and the support plate. When the linear drive device drives the pressing component to move downwards, the guide rod guides the pressing component to move smoothly in the vertical direction, preventing the pressing component from tilting or swaying during movement. The guiding effect of the guide rod ensures that the pressure-applying component and the physical marker actuator can be accurately aligned with the predetermined position of the remote control under test, improving the accuracy of the pressing action. The guide rod also enhances the structural connection rigidity between the pressing component and the support component, reducing vibration and impact during movement, which helps protect precision components such as the physical marker actuator and signal acquisition terminals.

[0034] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0035] 1. Floating support structure for precise and reliable contact: The support plate is floatingly supported by an elastic reset component. When the pressure component presses down on the remote control under test, the support plate is compressed and floats downwards. A limiting structure on the detection base plate limits the maximum downward movement of the support plate. When the support plate abuts against the limiting structure, the remote control under test and the signal acquisition terminal are in a stable contact and conductive state. This floating structure effectively absorbs product dimensional tolerances, prevents probe overpressure or poor contact, and ensures the consistency and reliability of signal acquisition.

[0036] 2. Integrated testing and marking with high process integration: The physical marking actuator and pressure application component are integrated on the pressure component. The physical marking of the remote control can be completed at the same time as the test is performed under pressure. The testing and marking are completed synchronously at the same station, eliminating the remote control transfer between testing and marking in the traditional solution, avoiding the risk of mixed materials, and improving production efficiency and the reliability of product quality traceability.

[0037] 3. Compact Integration of Shielding Environment and Fixture Structure: The shielding shell directly serves as the external structure of the test fixture, integrating load-bearing and pressure-resistant components internally, resulting in a compact overall structure. The mating surface between the cover and the base adopts a contact slope design that slopes upwards from the front to the back, increasing the contact area and shielding sealing effect. Simultaneously, it makes the front area of ​​the cover larger than the back area, resulting in a more aesthetically pleasing appearance and improved operational visibility.

[0038] 4. Multi-layer positioning structure for precise placement: The support plate is equipped with circumferential limiting components to form a positioning area, and the detection substrate is equipped with guide positioning components that pass through the positioning hole of the remote control for auxiliary positioning. Multiple positioning ensures the accuracy and consistency of remote control placement and improves the repeatability and accuracy of the test. Attached Figure Description

Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for explaining this utility model and are not intended to limit this utility model.

[0048] It should be noted that in the description of this utility model, the terms "upper," "lower," "front," "rear," "front," and "back," etc., indicate the orientation or positional relationship based on the operator's orientation when facing the test fixture. The side where the operator is located is "front," the side away from the operator is "back," the vertically upward direction is "upper," and the vertically downward direction is "lower." These terms are only for ease of description and simplification and should not be construed as limiting the scope of protection of this utility model.

[0049] The following is combined with Figures 1 to 7 The technical solution of this utility model will be described in further detail below.

[0050] This embodiment provides a test fixture for a remote control testing device. The test fixture is installed on the basic frame of the remote control testing device and is used to perform program burning, component parameter detection, static current testing, and physical marking of the remote control 100 under test.

[0051] The test fixture in this embodiment includes a shielding housing 1, a support component 2, and a pressure component 3. The shielding housing 1 provides an electromagnetically shielded test environment, the support component 2 is used to support and position the remote controller 100 under test, and the pressure component 3 is used to apply downward pressure to the remote controller 100 under test and perform electrical performance testing through the signal acquisition terminal 221.

[0052] The shielding housing 1 has a test chamber 11 inside, which is used to accommodate the bearing assembly 2 and the pressure-blocking assembly 3. The shielding housing 1 includes a base part 12 and a cover part 13. The base part 12 is a lower box structure, which is fixedly installed on the basic frame of the testing equipment. The cover part 13 is an upper cover structure, and the rear end of the cover part 13 is rotatably connected to the rear end of the base part 12 through a hinge shaft. An opening and closing drive member 14 is connected between the cover part 13 and the base part 12. In this embodiment, the opening and closing drive member 14 consists of two cylinders, which are symmetrically arranged on the left and right sides of the shielding housing 1. The cylinder body is hinged to the side of the base part 12, and the piston rod end of the cylinder is hinged to the side of the cover part 13. When the piston rod of the cylinder extends, it pushes the cover part 13 to flip upward around the hinge shaft to open; when the piston rod retracts, it pulls the cover part 13 to flip downward to close. The contact surface between the cover portion 13 and the base portion 12 is a contact slope 15 that slopes upward from the front to the back. That is, the front cover position of the cover portion 13 is lower than the rear cover position. This slope design increases the contact area of ​​the cover surface and enhances the shielding and sealing effect.

[0053] The back of the base 12 is provided with multiple electrical interfaces, which are used to make electrical connections with external test equipment (such as industrial control computer, I / O load board, LC bridge, programmer, digital multimeter, etc.) and to connect the test signals to the bearing component 2 and the pressure component 3 inside the shielding housing 1.

[0054] The support assembly 2 is located within the test chamber 11 of the base portion 12 and includes a base plate 21, a detection substrate 22, and a support plate 23. The base plate 21 is made of bakelite or insulating board and is fixedly mounted on the bottom surface of the base portion 12. Multiple support columns are provided on the base plate 21, and the detection substrate 22 is fixedly supported above the base plate 21 by the support columns. Multiple signal acquisition terminals 221 are provided on the detection substrate 22. Each signal acquisition terminal 221 is a metal probe with its tip extending upwards for making contact with the test contacts on the bottom surface of the remote control 100 under test. Each signal acquisition terminal 221 is connected to an electrical interface via wires to transmit the acquired electrical signals to external testing equipment.

[0055] A support plate 23 is disposed above the detection substrate 22, and the support plate 23 is supported on the detection substrate 22 by elastic reset members 233. In this embodiment, the elastic reset members 233 are four springs, which are respectively disposed below the four corners of the support plate 23. The upper end of the spring abuts against the bottom surface of the support plate 23, and the lower end of the spring abuts against the detection substrate 22. In its natural state, the springs support the support plate 23 upward, so that the lower surface of the support plate 23 and the upper surface of the detection substrate 22 maintain a certain distance. At this time, the top end of the signal acquisition terminal 221 is located below the support plate 23, and does not pass through the clearance hole 232 on the support plate 23 or only partially enters the clearance hole 232.

[0056] The support plate 23 has a positioning area 231 for placing the remote control 100 under test. Multiple limiting members 234 are arranged around the positioning area 231 on the support plate 23, forming the positioning area 231. The limiting members 234 are cylindrical or block-shaped structures, which horizontally limit the remote control 100 under test, allowing it to be placed quickly and accurately in the predetermined position.

[0057] The detection substrate 22 is provided with an upwardly extending guide positioning member 222, which is a cylindrical positioning pin. The top end of the guide positioning member 222 passes through a corresponding through hole on the support plate 23 and extends upward to a certain height from the upper surface of the support plate 23. When the remote control 100 under test is placed in the positioning area 231, the guide positioning member 222 passes through the positioning hole 101 on the remote control 100 under test to accurately assist in positioning the remote control 100 under test, ensuring that the test contacts on the bottom surface of the remote control are precisely aligned with the signal acquisition terminals 221 on the detection substrate 22 in the vertical direction.

[0058] The carrier plate 23 is provided with clearance holes 232 corresponding to the positions of each signal acquisition terminal 221. The clearance holes 232 are through holes that penetrate the upper and lower surfaces of the carrier plate 23. When the carrier plate 23 floats downward, the top of the signal acquisition terminal 221 can extend upward through the clearance holes 232 and make contact with the test contact on the bottom surface of the remote control under test 100.

[0059] The detection substrate 22 is also provided with a limiting structure 223, which is a cylindrical limiting block fixedly installed on the upper surface of the detection substrate 22. Its height is precisely determined according to the design contact stroke of the signal acquisition terminal 221. When the support plate 23 is compressed and floats downward until it abuts against the upper end surface of the limiting structure 223, the support plate 23 stops moving downward. At this time, the test contact on the bottom surface of the remote control under test 100 and the top of the signal acquisition terminal 221 are in a stable and reliable contact state. The limiting structure 223 provides a rigid end point for the downward movement of the support plate 23, ensuring the consistency of the stroke and the reliability of the contact each time it is pressed down.

[0060] The support assembly 2 also includes a guide shaft 24 and a bushing 25. The bushing 25 is fixedly mounted on the detection base plate 22, and its inner hole is a smooth cylindrical surface. The upper end of the guide shaft 24 is fixedly connected to the bottom surface of the support plate 23, and the lower end of the guide shaft 24 passes through the inner hole of the bushing 25 and extends downward through the detection base plate 22. The outer diameter of the guide shaft 24 and the inner diameter of the bushing 25 are clearance-fitted, allowing the guide shaft 24 to slide smoothly along the axial direction of the bushing 25. When the support plate 23 is compressed and floats downward, the guide shaft 24 slides downward along the bushing 25, providing precise linear guidance for the floating movement of the support plate 23, ensuring that the support plate 23 always maintains a horizontal posture during the floating process and does not tilt or deviate. Four guide shafts 24 and bushings 25 are correspondingly arranged, and four springs are sleeved on the outer periphery of the guide shaft 24.

[0061] The pressing component 3 is located above the supporting component 2 and is used to apply downward pressing force to the remote control 100 under test. The pressing component 3 includes an upper fixing plate 31 and an upper pressing base plate 32. A linear drive device 4 is provided above the upper fixing plate 31. In this embodiment, the linear drive device 4 is a cylinder. The cylinder body is fixedly installed on the top plate above the upper fixing plate 31. The top plate is fixedly installed on the inner top surface of the cover portion 13 and opens or closes together with the cover portion 13. The piston rod of the cylinder is connected to the upper fixing plate 31. The upper pressing base plate 32 is fixedly installed below the upper fixing plate 31 and moves up and down together with the upper fixing plate 31 under the drive of the linear drive device 4.

[0062] The upper pressure plate 32 is provided with multiple pressure-applying elements 34 and a physical marking actuator 33. The pressure-applying elements 34 are cylindrical pressure bars with a flat lower end surface, used to evenly transmit pressure to the upper surface of the remote control 100 under test. The physical marking actuator 33 is a polishing probe used to polish and mark the surface of the remote control 100 under test after the test is passed, enabling product quality traceability. The lower end of the physical marking actuator 33 is flush with the lower end surface of the pressure-applying elements 34, and simultaneously contacts the upper surface of the remote control 100 under test under the drive of the linear drive device 4.

[0063] The upper fixed plate 31 is provided with a through clearance groove 35, which is a through groove that penetrates the upper and lower surfaces of the upper fixed plate 31. The main body of the physical marking actuator 33 is installed in the through clearance groove 35, and its drive motor or clamping part is fixed above the upper fixed plate 31 or inside the groove. The grinding head at its lower end extends downward to below the upper pressing base plate 32. The pressure applying members 34 are provided on the side of the physical marking actuator 33, respectively arranged on the left and right sides or around the physical marking actuator 33, forming a spatially complementary layout with the physical marking actuator 33. The two are reasonably arranged within a limited cross-section and do not interfere with each other.

[0064] A guide rod 36 is also connected between the pressing component 3 and the support plate 23. The upper end of the guide rod 36 is fixed to the upper pressing base plate 32 or the upper fixed plate 31, and the lower end of the guide rod 36 passes through a corresponding guide hole on the support plate 23. When the linear drive device 4 drives the pressing component 3 to move downward, the guide rod 36 slides along the guide hole on the support plate 23, providing precise guidance for the downward pressing movement of the pressing component 3, preventing the pressing component 3 from deflecting or shaking during the movement, and ensuring that the pressure application component 34 and the physical marker actuator 33 can be accurately aligned with the predetermined position of the remote controller 100 under test.

[0065] The working process of this embodiment is as follows:

[0066] In the initial state, the opening and closing drive member 14 drives the cover part 13 to be in the open state, the pressing component 3 flips up with the cover part 13, and the support plate 23 is in the floating position under the support of the elastic reset member 233. There is a certain distance between the lower surface of the support plate 23 and the upper end surface of the limiting structure member 223.

[0067] The operator or robotic arm places the remote control 100 under test on the positioning area 231 of the support plate 23. The limiting member 234 performs coarse horizontal positioning of the outer periphery of the remote control, and the guide positioning member 222 passes through the positioning hole 101 on the remote control for precise positioning. After the remote control is placed in place, the test contact on the bottom surface of the remote control is located directly above the signal acquisition terminal 221, with a gap between them.

[0068] The opening and closing drive 14 drives the cover part 13 to flip downward and close, and the cover surface between the cover part 13 and the base part 12 fits tightly to form an electromagnetically shielded test cavity 11. The linear drive device 4 drives the pressing component 3 to move downward, and the pressing component 34 and the physical mark actuator 33 descend together with the upper pressing base plate 32 until they contact the upper surface of the remote controller 100 under test and push the remote controller downward.

[0069] The workpiece under test is subjected to a downward pressure, and the remote control 100 under test and the support plate 23 float downward synchronously against the elastic force of the elastic reset member 233. The guide shaft 24 slides along the bushing 25, and the support plate 23 moves downward steadily while maintaining a horizontal posture. The top of the signal acquisition terminal 221 extends upward through the clearance hole 232 on the support plate 23, gradually approaching and finally contacting the test contact on the bottom surface of the remote control. The support plate 23 continues to move downward until it abuts against the upper end surface of the limiting structure 223. At this time, the remote control 100 under test and the signal acquisition terminal 221 are in a stable contact and conduction state.

[0070] At this time, the external testing equipment performs the following tests on the remote control 100 under test through the signal acquisition terminal 221: LC bridge acquisition confirms whether the parameters of components such as resistors, capacitors, and inductors on the PCBA board meet the set requirements; the programmer programs the PCBA board; and after power-on, the static current is acquired through a digital multimeter. During the test, the pressing component 3 maintains a stable clamping force to ensure reliable contact between the signal acquisition terminal 221 and the test contact.

[0071] After the test is passed, the physical marking actuator 33 is activated to grind and mark the upper surface of the remote control 100 under test, fixing the test results on the product in the form of physical markings for easy quality traceability in the future.

[0072] After testing and marking are completed, the linear drive device 4 drives the pressure assembly 3 to reset upwards, and the pressure component 34 and the physical marking actuator 33 disengage from the remote controller 100 under test. The support plate 23 floats upwards and resets under the rebound force of the elastic reset component 233. The opening and closing drive component 14 drives the cover part 13 to flip upwards and open, allowing the operator or robot arm to remove the remote controller that has completed testing and marking, place the next remote controller 100 under test, and enter the next test cycle.

[0073] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
