Description

Technical Field

[0001] This utility model relates to a testing fixture for wired controllers. Background Technology

[0002] With the development of electronic equipment technology, wired controllers, as control components for various electrical appliances (such as air conditioners and home appliances), are becoming increasingly widely used. To ensure the quality of wired controllers before they leave the factory, they need to be tested in multiple dimensions, including power-on performance, button functions, display status, and program version.

[0003] Currently, wired controllers generally use quick-connect sockets for circuit connection. However, existing wired controller testing methods have obvious drawbacks: most testing fixtures require manual connection of the wired controller's circuit interface, which is not only cumbersome and time-consuming, resulting in low testing efficiency; moreover, the testing process can only test the power-on performance, making it difficult to simultaneously complete the testing of the wired controller's buttons, screen defects, and program version reading. Additional equipment or manual verification is required, further increasing testing costs and time, and failing to meet the rapid testing needs in the mass production of wired controllers.

[0004] Therefore, there is an urgent need for a tooling that is compatible with quick-connect socket wire controllers and can achieve multi-dimensional rapid testing to solve the problems of low efficiency and limited functionality of existing testing methods. Utility Model Content

[0005] To address the aforementioned issues, this utility model provides a wired controller testing fixture that enables rapid power-on and multi-dimensional synchronous testing of the wired controller, improving testing efficiency and comprehensiveness, and effectively solving the problems mentioned in the background art.

[0006] The technical solution adopted in this utility model is:

[0007] A wired controller testing fixture includes a fixture body, and a drive assembly, a detection assembly, and a clamping and positioning assembly disposed on the fixture body;

[0008] The drive assembly includes a cylinder, which is fixedly mounted on the top of the tooling body;

[0009] The clamping and positioning assembly includes a cover plate and a base plate. The cover plate is fixedly connected to the output end of a cylinder, and the cylinder can drive the cover plate to move up and down. The base plate is fixed on the tooling body and located directly below the cover plate, and positioning blocks are provided around the top of the base plate.

[0010] The detection component includes an ammeter and a pin. The ammeter is embedded in the fixture body, and the pin is vertically fixed to the base plate of the clamping and positioning component. The number and arrangement of the pins are adapted to the quick-connect socket on the wired controller.

[0011] Preferably, the system also includes a control component, which includes a controller, three jog buttons, and a main switch. The main switch and the three jog buttons are electrically connected to the controller, which is also electrically connected to the cylinder and an ammeter and voltmeter. Of the three jog buttons, the first is used to control the manual extension of the cylinder, the second is used to control the manual retraction of the cylinder, and the third is used to control the automatic retraction of the cylinder back to its initial state. The main switch is used to control the on / off state of the circuit.

[0012] Preferably, a flexible clamping block is provided at the bottom of each of the left and right sides of the cover plate, and the top of the flexible clamping block is fixedly connected to the cover plate through a base.

[0013] Preferably, the base of the flexible clamping block is fixedly connected to the cover plate by adjusting bolts, and the cover plate is provided with sliding holes that match the adjusting bolts, and the adjusting bolts can slide in the left and right directions within the sliding holes.

[0014] Preferably, the base plate is fixed with a transverse slide rail and a longitudinal slide rail. The transverse slide rail matches the positioning blocks on the left and right sides of the base plate, so that the positioning blocks on the left and right sides can slide left and right along the transverse slide rail. The longitudinal slide rail matches the positioning blocks on the front and rear sides of the base plate, so that the positioning blocks on the front and rear sides can slide back and forth along the longitudinal slide rail. The positioning blocks are fastened to the transverse slide rail or the longitudinal slide rail by fastening bolts.

[0015] Preferably, the flexible clamping block is made of sponge.

[0016] Preferably, the cover plate is provided with multiple guide holes, and the tooling body is fixed with guide posts that match the guide holes.

[0017] The innovative points of this utility model are as follows:

[0018] I. Automated and Precise Docking Design: Replacing manual operation and solving the pain point of "low efficiency of manual docking".

[0019] Existing testing fixtures require manual connection of the controller circuit interface, which is not only cumbersome and time-consuming, but also prone to poor contact due to human error. This solution achieves automation and precision in circuit connection through a combination design of "cylinder drive + precise positioning + pins compatible with quick-connect sockets", as detailed below:

[0020] 1. Power-driven automation: The drive component uses a cylinder (fixed to the top of the tooling body) to directly drive the cover plate of the clamping and positioning component to move up and down. During testing, the cylinder drives the cover plate to press down, which can automatically complete the clamping of the wire controller and the circuit connection. After the test is completed, the cylinder drives the cover plate to rise and reset. There is no need for manual pressing or plugging and unplugging of the interface, which completely replaces manual operation and reduces the single docking time from "tens of seconds for manual operation" to "seconds for cylinder drive", which greatly improves the testing efficiency.

[0021] 2. Precise positioning and docking: The base plate of the clamping and positioning component is fixed to the tooling body, and positioning blocks are set around the top, which can quickly limit the placement position of the wire controller and avoid misalignment caused by the wire controller shifting.

[0022] The pins of the detection component are vertically fixed to the base plate, and the number and arrangement of the pins are fully adapted to the pin layout of the quick-connect socket of the wired controller. When the cover plate is pressed down, the pins can be accurately inserted into the corresponding pins of the quick-connect socket, realizing the integrated automatic completion of "positioning-pressing-circuit connection". The docking accuracy error can be controlled within millimeters, avoiding the contact problems caused by manual docking.

[0023] II. Multi-dimensional Integrated Testing Design: Breaking through the limitations of "single power-on testing" to achieve "one-stop testing"

[0024] In the background technology, existing tooling can only test the power-on performance of the wired controller. Button functionality, screen defects, and program version verification require additional equipment or manual verification, resulting in a fragmented testing process and high costs. This solution integrates multi-dimensional testing functions into a single tooling through a "pin adapter + detection component linkage" design, as detailed below:

[0025] Full coverage of detection functions: The pin arrangement not only matches the "power-on pins" of the quick-connect socket, but also covers the "signal transmission pins" and "data reading pins".

[0026] Power-on performance test: The power pin of the quick-connect socket is connected to the pin. With the help of the current and voltage meters embedded in the tool body, the current and voltage parameters of the wired controller are detected in real time after power-on to determine whether the power-on is normal.

[0027] Button function test: The push pin connects to the button signal pin of the quick-connect socket. When the button of the wired controller is pressed, the signal is transmitted to the controller through the push pin. It can be used to simultaneously determine whether the button has triggered a valid signal (if there is no signal, the button is determined to be faulty).

[0028] Screen defect detection: The pin connects to the screen driver pin of the quick-connect socket - by detecting whether the signal of the screen driver circuit is normal, it can be indirectly determined whether there are defects such as black screen or screen distortion (no need for manual visual inspection).

[0029] Program version reading: The data transmission pin of the quick-connect socket connected to the pin can communicate with the chip of the controller and the wired controller to directly read the program version information (such as version number and production date) without the need for an additional computer or dedicated code reading device;

[0030] Synchronized testing: The above-mentioned "power-on - button-screen - program version" test can be completed synchronously after one cylinder press-down and circuit connection. The testing process is simplified from "multi-device / multi-step split testing" to "one-stop synchronous testing". The testing time of a single wired controller is reduced by more than 50%, and there is no need for manual transfer of wired controllers between different devices, reducing manual intervention and errors.

[0031] III. Adjustable Positioning Structure: Breaking through the limitations of "single-specification adaptation" and improving the versatility of tooling.

[0032] Existing testing fixtures are mostly designed with fixed dimensions, only compatible with a single type of wired controller. When the size of the wired controller or the position of the quick-connect socket changes, the entire fixture needs to be replaced, increasing equipment costs and changeover time. This solution uses a "slide rail + movable positioning block" design to achieve compatibility with different specifications of wired controllers, as detailed below:

[0033] 1. The positioning blocks are flexibly adjustable: The base plate is fixed with a horizontal slide rail (corresponding to the left and right dimensions of the wired controller) and a vertical slide rail (corresponding to the front and back dimensions of the wired controller), and the positioning blocks around the base plate are matched with the slide rails respectively.

[0034] The positioning blocks on the left and right sides can slide left and right along the horizontal slide rail to accommodate wired controllers of different widths.

[0035] The positioning blocks on the front and rear sides can slide back and forth along the longitudinal slide rail to accommodate wired controllers of different lengths.

[0036] 2. Stable locking after adjustment: After the positioning block slides to the target position, it can be fixed to the slide rail by fastening bolts to ensure that the positioning block does not shift during the test. No parts need to be replaced. By simply adjusting the position of the positioning block, it can be adapted to wired controllers within the predetermined size range. It is compatible with the test of wired controllers of various home appliances (air conditioners, refrigerators, washing machines, etc.) and the tooling reuse rate is increased by more than 80%.

[0037] IV. Flexible and Adjustable Compression Protection Design: Balancing Compression Stability with Controller Protection

[0038] Most wired controllers have plastic housings, with the display screen on the front. Using hard contact for clamping can easily cause deformation or scratches. Furthermore, the clamping positions of different sized wired controllers need to be compatible; otherwise, uneven force may lead to misalignment. This solution addresses these issues through a design using "flexible materials + adjustable clamping position," as detailed below:

[0039] 1. Flexible clamping to prevent damage: Flexible clamping blocks (made of sponge material) are set at the bottom of the left and right sides of the cover plate. The sponge has a certain elasticity. When the cover plate is pressed down, it can fit the top of the wired controller through elastic deformation, which not only ensures sufficient clamping force (to prevent the wired controller from shifting during testing), but also avoids hard contact that may cause scratches, indentations and other damage to the plastic shell, thus protecting the integrity of the wired controller's appearance.

[0040] 2. Adjustable clamping position: The top of the flexible clamping block is connected to the cover plate via the base, and the base is fixed to the cover plate via adjusting bolts. The cover plate has sliding holes (extending in the left and right direction) that match the adjusting bolts. After loosening the adjusting bolts, the base can be moved left and right along the sliding holes to adjust the position of the flexible clamping block, ensuring that the clamping block can accurately act on wire controllers of different widths.

[0041] 5. Dual-mode control: "Automatic + Manual" balancing "batch efficiency" and "operational flexibility"

[0042] Batch testing requires automation to improve efficiency, while tooling debugging and troubleshooting require manual control for ease of operation. Existing tooling often only supports a single mode, lacking flexibility. This solution achieves "automatic + manual" dual-mode compatibility through the logic design of the control components, as detailed below:

[0043] The control component features innovative logic: it includes a controller, three jog buttons, and a main switch. The electrical connections between these components are: main switch → controller → cylinder / ammeter / voltmeter. The three jog buttons are linked to the controller, with clearly defined functional divisions.

[0044] Button 1: Manually push out the cylinder (suitable for tooling debugging, wired controller placement and calibration, etc., the cover plate pressing stroke can be manually controlled).

[0045] Button 2: Manually retracts the cylinder (suitable for emergency situations, such as quickly lifting the cover plate if an abnormality is detected during testing);

[0046] Button 3: Controls the cylinder to automatically retract to its initial state (automatically resets after batch testing, no manual operation required).

[0047] VI. Guiding and Positioning Auxiliary Structure: Ensures docking accuracy and avoids "misalignment leading to detection failure".

[0048] When the cylinder drives the cover plate to move up and down, lateral deviation can easily cause the ejector pin to fail to accurately insert into the quick-connect socket, or even damage the ejector pin or the wired controller. This solution uses a "guide hole + guide post" design to ensure the stability of the cover plate's movement trajectory, as detailed below:

[0049] Multiple guide holes are provided on the cover plate, and guide posts that perfectly match the size and position of the guide holes are fixed on the tooling body. When the cylinder drives the cover plate to move up and down, the guide posts slide along the guide holes, forcibly limiting the cover plate to move only in the vertical direction, avoiding lateral offset, ensuring that the ejector pin can accurately align with the quick-connect socket every time, increasing the alignment success rate to over 99.9%, and reducing the need for retesting or component damage caused by offset.

[0050] This utility model achieves automated and precise circuit docking through "cylinder drive + precise positioning + compatible quick-connect socket pins". It integrates multi-dimensional synchronous detection of power performance, button function, screen defects, and program version. Furthermore, it relies on adjustable positioning blocks and flexible clamping blocks to adapt to different specifications of wired controllers and protect their appearance, which greatly improves detection efficiency and accuracy. It effectively solves the problems of cumbersome manual operation, low efficiency, single function, and poor adaptability in traditional detection. Attached Figure Description

[0061] The present invention will now be described in further detail with reference to specific embodiments and accompanying drawings.

[0062] like Figure 1-4 As shown, a wire controller testing fixture includes a fixture body 1, and a drive assembly, a detection assembly, a clamping and positioning assembly, and a control assembly disposed on the fixture body 1.

[0063] The drive assembly includes a cylinder 2, which is fixedly mounted on the top of the tooling body 1;

[0064] The clamping and positioning assembly includes a cover plate 3 and a base plate 4. The cover plate 3 is fixedly connected to the output end of the cylinder 2, and the cylinder 2 can drive the cover plate 3 to move up and down. The base plate 4 is fixed on the tooling body 1 and located directly below the cover plate 3. Positioning blocks 5 are provided around the top of the base plate 4.

[0065] The detection component includes an ammeter and a pin. The ammeter is embedded in the fixture body 1, and the pin is vertically fixed on the base plate 4 of the clamping and positioning component. The number and arrangement of the pins are adapted to the quick-connect socket on the wire controller 14.

[0066] The control component includes a controller, three jog buttons 6, and a main switch 7. The main switch 7 and the three jog buttons 6 are electrically connected to the controller. The controller is also electrically connected to the cylinder 2 and an ammeter and voltmeter. Of the three jog buttons 6, the first is used to control the manual extension of the cylinder 2, the second is used to control the manual retraction of the cylinder 2, and the third is used to control the automatic retraction of the cylinder 2 back to its initial state. The main switch 7 is used to control the on / off state of the circuit.

[0067] A flexible pressing block 8 is provided at the bottom of each of the left and right sides of the cover plate 3. The top of the flexible pressing block 8 is fixedly connected to the cover plate 3 through the base.

[0068] The base of the flexible clamping block 8 is fixedly connected to the cover plate 3 by adjusting bolts. The cover plate 3 has a sliding hole 9 that matches the adjusting bolts, and the adjusting bolts can slide in the left and right directions within the sliding hole 9.

[0069] The base plate 4 is fixed with a transverse slide rail 10 and a longitudinal slide rail 11. The transverse slide rail 10 matches the positioning blocks 5 on the left and right sides of the base plate 4, so that the positioning blocks 5 on the left and right sides can slide left and right along the transverse slide rail 10. The longitudinal slide rail 11 matches the positioning blocks 5 on the front and rear sides of the base plate 4, so that the positioning blocks 5 on the front and rear sides can slide back and forth along the longitudinal slide rail 11. The positioning blocks 5 are fastened to the transverse slide rail 10 or the longitudinal slide rail 11 by fastening bolts.

[0070] The flexible clamping block 8 is made of sponge.

[0071] The cover plate 3 has multiple guide holes 12, and the tooling body 1 has guide posts 13 that match the guide holes.

[0072] This utility model revolves around the entire process of "adaptation and adjustment - precise positioning - automated docking - multi-dimensional synchronous detection - flexible reset". Through the synergistic effect of four major components—drive, detection, clamping and positioning, and control—it achieves efficient and comprehensive detection of the wired controller, which can be divided into the following 6 core stages:

[0073] I. Initial Adaptation and Adjustment Phase: Adjust tooling as needed to adapt to different specifications of wired controllers.

[0074] Before testing, the fixture structure needs to be adjusted according to the size of the wired controller to be tested and the position of the quick-connect socket to ensure accurate fit. The core adjustment steps are as follows:

[0075] 1. Position adjustment of positioning block:

[0076] The base plate is fixed with a horizontal slide rail (corresponding to the width direction of the wired controller) and a vertical slide rail (corresponding to the length direction of the wired controller):

[0077] The positioning blocks on the left and right sides slide along the transverse slide rail until they match the width of the wired controller to be tested;

[0078] The positioning blocks on the front and rear sides slide along the longitudinal slide rail until they match the length of the wired controller to be tested;

[0079] After adjustment, tighten the fastening bolts on the positioning block to lock it on the slide rail, forming a dedicated positioning area for the wired controller of this specification, and preventing the wired controller from shifting during testing;

[0080] 2. Adjustment of the position of the flexible clamping block:

[0081] The flexible clamping blocks (made of sponge) on both sides of the cover plate are connected by an "adjusting bolt + sliding hole" structure.

[0082] Loosen the adjusting bolt and move the base of the clamping block along the left and right sliding holes on the cover plate so that the clamping block can be accurately aligned with the target area on the top of the wire controller.

[0083] After adjustment, tighten the adjusting bolts to ensure that stable pressure is provided during subsequent compression, while also protecting the wire controller housing through the elastic deformation of the sponge.

[0084] 3. Guide structure pre-fit:

[0085] The guide holes on the cover plate are pre-matched with the guide posts on the tooling body (the size and position are completely corresponding), and no additional adjustment is required. It is only necessary to confirm that the guide posts are not stuck, so as to ensure that the cover plate slides stably in the vertical direction when it moves laterally and avoids lateral deviation.

[0086] II. Wired controller positioning stage: rapid placement, relying on positioning blocks to define the position.

[0087] Place the wired controller to be tested in the positioning area of ​​the base plate: the wired controller will fit tightly with the positioning blocks that have been adjusted in advance. The positioning blocks directly limit the front, back, left and right positions of the wired controller, eliminating the need for repeated manual calibration and achieving "accurate placement". This ensures that the quick-connect socket of the wired controller and the pin on the base plate are on the same vertical axis (to prepare for subsequent precise docking).

[0088] III. Automated Drive and Circuit Interconnection Stage: Cylinder Drive, Achieving Integrated "Pressure-Interconnection"

[0089] This stage is the core of replacing manual docking, and it is completed collaboratively by the control component, drive component, and clamping and positioning component. The specific action logic is as follows:

[0090] 1. Start the driver system:

[0091] Turn on the main switch of the control unit. The controller is powered on and establishes a signal connection with the cylinder, ammeter, and voltmeter. Select the control mode according to your needs ("Manual Mode" for manual debugging, "Automatic Mode" for batch testing):

[0092] Manual mode: Press the "first jog button" and the controller sends an "eject command" to the cylinder;

[0093] Automatic mode: After the detection process is triggered, the controller automatically sends an "ejection command" to the cylinder;

[0094] 2. The cover plate moves vertically downwards, simultaneously completing the "pressing + docking":

[0095] After receiving the command, the cylinder (fixed to the top of the tooling body) drives the cover plate to move vertically downward along the defined trajectory of the guide post and guide hole:

[0096] Step 1: The flexible clamping block at the bottom of the cover plate first contacts the top of the wire controller. As the cover plate continues to move down, the sponge undergoes elastic deformation, gradually applying stable pressure to firmly press the wire controller onto the base plate (to prevent the wire controller from shifting during testing).

[0097] Step 2: The pins on the base plate (the number and arrangement of which are fully compatible with the pins of the quick-connect socket of the wired controller) are precisely inserted into the corresponding pins of the quick-connect socket as the cover plate is pressed, instantly completing the connection between the wired controller and the tooling detection circuit (the docking accuracy reaches the millimeter level, with no problem of poor human contact).

[0098] IV. Multi-dimensional synchronous detection stage: Relying on the multi-pin adapter of the probe, "one-stop" detection is achieved.

[0099] After the circuit connection is completed, the detection component and the control component work together to synchronously collect multi-dimensional information from the wired controller through the "power pins, signal pins, and data pins" covered by the pins. The specific detection logic is as follows:

[0100] Detection Dimensions Core principle (e.g., thimble + component collaboration) Judgment method Power-on performance testing The pin connects to the "power pin" of the quick-connect socket, and the current and voltage parameters of the wired controller are collected in real time by the ammeter and voltmeter (embedded in the fixture body). If the current / voltage is within the preset normal range, the power supply is considered normal; if it exceeds the range, a power supply fault is considered. Button function test The ejector pin connects to the "button signal pin" of the quick-connect socket. When the button of the wired controller is pressed, the trigger signal is transmitted to the controller through the ejector pin. If the controller receives a valid signal, the button is considered to be working properly; if no signal is received, the button is considered to have poor contact or be malfunctioning. Screen Defect Detection The pin connects to the "screen driver pin" of the quick-connect socket, and the controller monitors the signal stability of the screen driver circuit in real time. A continuous and uninterrupted drive signal indicates no blackouts or screen artifacts; an abnormal signal indicates a screen defect. Program version reading The pin connects to the "data transmission pin" of the quick-connect socket, through which the controller establishes communication with the wired controller chip. It can directly read information such as the program version number and production date from the chip, without the need for an additional computer or code reading device.

[0101] The above four tests are performed simultaneously, eliminating the need for manual transfer of the wired controller between different devices, and reducing the testing time per unit by more than 50% compared to the traditional method;

[0102] V. Post-test reset stage: Flexible control and quick replacement of the wired controller.

[0103] After the test is completed, select the reset method according to the control mode. The core actions are as follows:

[0104] 1. Manual reset (debugging / emergency scenarios):

[0105] Press the "second jog button", the controller sends a "retraction command" to the cylinder, the cylinder drives the cover plate to rise vertically, the ejector pin disengages from the quick connector, the flexible clamping block releases the wire controller, and the wire controller that has been tested can be manually removed.

[0106] 2. Automatic Reset (Batch Testing Scenarios)

[0107] Pressing the "third jog button" triggers the "automatic reset logic" of the controller. After the test is completed, the cylinder automatically drives the cover plate to rise and reset. No manual intervention is required, and the next wired controller to be tested can be placed directly, improving the efficiency of batch testing.

[0108] The entire workflow is structured around a controller as the central hub, cylinders as the power source, positioning blocks and guide structures as precision assurance, and ejector pins as the detection bridge. It addresses the pain points of traditional testing through four core logics:

[0109] 1. Replacing manual insertion and removal with "cylinder drive + precise docking" significantly improves docking efficiency;

[0110] 2. Integrating multi-dimensional detection with "multi-pin adapter for ejector pins" breaks through the limitations of single power-on detection;

[0111] 3. The "slide rail + adjustable structure" design is compatible with multiple specifications of wired controllers, reducing tooling replacement costs;

[0112] 4. The "flexible clamping + guiding positioning" method balances detection stability with protection of the wired controller, reducing the risk of damage;

[0113] Ultimately, this will enable "high efficiency, precision, versatility, and safety" in the batch testing of wired controllers.

[0114] Finally, it should be noted that the above examples are merely specific embodiments of this utility model. Obviously, this utility model is not limited to the above embodiments and can have many variations. All variations that can be directly derived or conceived by those skilled in the art from the disclosure of this utility model should be considered within the protection scope of this utility model.
