Description

Technical Field

[0001] This utility model relates to the field of automated testing technology, specifically to a controller testing device. Background Technology

[0002] During the production testing of controllers (such as industrial PLCs and automotive ECUs), it is necessary to test their power-on interfaces (such as power terminals and grounding terminals) and signal interfaces (such as CAN bus and digital I / O ports) one by one to verify the reliability of electrical connections and the accuracy of signal transmission.

[0003] Traditional testing methods primarily involve manual testing: operators hold the test terminals and sequentially insert them into each interface of the controller to perform power-on and signal detection. This method has significant drawbacks:

[0004] Low testing efficiency: Each controller has a large number of interfaces, and manually plugging and unplugging them one by one is time-consuming and labor-intensive for workers;

[0005] Risk of poor contact: Uneven manual insertion force can easily lead to poor contact between the test terminal and the interface, resulting in misjudgment;

[0006] Interface damage hazard: When operators apply excessive force, mechanical stress is generated between the test terminal and the interface metal spring, which can cause plastic deformation of the interface and damage to the controller. Utility Model Content

[0007] The purpose of this invention is to provide a controller testing device that can effectively solve the problems of existing controllers relying on manual testing, which is inefficient and prone to inaccurate testing and controller damage due to manual plugging and unplugging of terminals.

[0008] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0009] A controller testing device, comprising:

[0010] frame;

[0011] A replaceable mounting base is provided on the frame, the mounting base having a positioning groove adapted to the controller under test, and the mounting base is connected to the frame via a quick-change positioning assembly;

[0012] The clamping mechanism includes a power assembly fixed to the frame and a clamping member connected to the output end of the power assembly, wherein the clamping member is disposed above the positioning groove.

[0013] A sliding test mechanism includes a sliding seat, a test connector detachably mounted on the sliding seat, and a drive assembly. The sliding seat is slidably connected to the frame via a sliding guide assembly. The drive assembly is driven by the sliding seat and controls its movement so that the test connector is aligned and connected with the controller under test.

[0014] In the aforementioned controller testing device, the sliding guide assembly includes a combination structure of a slide rail and a slider. The slide rail is fixed to the frame, and the sliding seat slides in cooperation with the slide rail through the slider.

[0015] In the aforementioned controller testing device, the drive assembly includes a servo motor, a threaded lead screw, and a nut. The lead screw is rotatably connected to the frame, and the nut is fixedly connected to the bottom of the sliding seat. The servo motor drives the lead screw to rotate through a transmission component.

[0016] In the aforementioned controller testing device, the transmission component includes a synchronous belt and a synchronous pulley connected to a lead screw, and the servo motor drives the synchronous pulley to rotate via the synchronous belt.

[0017] In the aforementioned controller testing device, the quick-change positioning component includes a mutually interlocking positioning structure disposed between the frame and the fixed seat, wherein the mutually interlocking positioning structure constrains the displacement of the fixed seat in the horizontal direction.

[0018] In the aforementioned controller testing device, the interlocking positioning structure includes the cooperation of a protrusion and a recess, wherein the protrusion is any one of a columnar, conical, or blocky geometric shape, and the shape of the recess is adapted to the protrusion.

[0019] In the aforementioned controller testing device, the test connector and the sliding seat are connected by a plug-in quick-change structure. The plug-in quick-change structure includes corresponding sockets provided on the sliding seat and the test connector, as well as a connector that can be detachably inserted into the sockets.

[0020] In the aforementioned controller testing device, the sliding seat is provided with multiple sets of sockets, and the socket position of the test connector matches a specific set of sockets on the sliding seat.

[0021] In the aforementioned controller testing device, the power component includes a rotary clamping cylinder, the piston of which is fixedly connected to a clamping component.

[0022] In the controller testing device described above, the sliding seat is further provided with wiring terminals, which include a first wiring block and a second wiring block, and the first wiring block is electrically connected to the test connector.

[0023] Compared with the prior art, the advantages of this utility model are:

[0024] The mounting base features a positioning groove adapted to the controller under test (DUT), enabling rapid and accurate positioning of the controller and ensuring precise alignment between the test interface and the test connector. The quick-change positioning assembly allows for rapid replacement of the mounting base, meeting the testing needs of different controller models, reducing changeover time, and improving production line flexibility. The clamping mechanism, driven by a power component, automatically clamps and secures the controller above the positioning groove, ensuring stable controller position during testing and reducing the risk of poor contact. The sliding test mechanism, controlled by a drive component, moves the sliding seat, automatically aligning and connecting the test connector to the controller interface, replacing manual insertion and removal operations, significantly improving testing efficiency, reducing worker workload, and ensuring uniform and controllable force when the test connector is inserted into the DUT, preventing damage to the DUT. The sliding guide assembly ensures smooth and precise movement of the sliding seat, avoiding damage caused by collisions between the test connector and the interface, and improving test reliability.

[0025] Furthermore, the sliding guide assembly includes a combination structure of a slide rail and a slider. The slide rail is fixed to the frame, and the sliding seat slides in conjunction with the slide rail via the slider. This combination of slide rail and slider provides a clear linear motion guide path, ensuring that the sliding seat can only move along the slide rail direction during movement, avoiding lateral offset or wobbling. This structure ensures the alignment accuracy of the test connector and the controller interface, preventing poor contact or interface damage due to positional deviations, and improving the reliability of test results.

[0026] Furthermore, the drive assembly includes a servo motor, a threaded lead screw, and a nut. The lead screw is rotatably connected to the frame, and the nut is fixedly connected to the bottom of the sliding seat. The servo motor drives the lead screw to rotate through a transmission component. The threaded engagement between the lead screw and the nut provides precise transmission characteristics, and through the precise control of the servo motor, micron-level displacement accuracy of the sliding seat can be achieved. Compared to pneumatic or belt drives, the motion trajectory of the lead screw drive is easier to program precisely through a servo system, making it suitable for the automated control of complex testing processes (such as multi-stage step-by-step testing).

[0027] Furthermore, the transmission component includes a synchronous belt and a synchronous pulley connected to the lead screw, and the servo motor drives the synchronous pulley to rotate through the synchronous belt. The meshing transmission between the synchronous belt and the synchronous pulley achieves slip-free transmission through tooth profile matching, avoiding the slippage phenomenon of traditional belt drives, ensuring that the rotational speed of the servo motor is accurately transmitted to the lead screw, and maintaining the uniformity of the sliding seat's movement speed.

[0028] Furthermore, the quick-change positioning assembly includes an interlocking positioning structure disposed between the frame and the fixed seat, the interlocking positioning structure constraining the displacement of the fixed seat in the horizontal direction. The quick-change positioning assembly requires no screws, bolts, or other fasteners, and achieves the installation and removal of the fixed seat through the mechanical cooperation of the interlocking structure, supporting "plug and play" operation.

[0029] Furthermore, the interlocking positioning structure includes the cooperation of protrusions and recesses. The protrusions can be any of the following geometric shapes: columnar, conical, or blocky. The shapes of the recesses are adapted to the protrusions. The shape of the protrusions can be flexibly selected according to the size, weight, and positioning accuracy requirements of the fixing seat. Both the protrusions and recesses are regular geometric shapes, requiring no complex surface machining. High-precision manufacturing can be achieved through conventional machining processes such as milling and turning.

[0030] Furthermore, the test connector and the sliding seat are connected via a plug-in quick-change structure, which includes corresponding sockets on the sliding seat and the test connector, as well as detachable connectors that can be inserted into the sockets. The standardized socket design enables interchangeability of test connectors with different functions, adapting to the needs of multi-station parallel testing or rapid switching of test items on production lines, and is particularly suitable for the efficient operation of automated testing lines.

[0031] Furthermore, the sliding base is provided with multiple sets of sockets, and the socket position of the test connector matches a specific set of sockets on the sliding base. The same sliding base supports multiple installation positions for test connectors, and each test connector can find a corresponding set of sockets, realizing the matching and plugging of the test connector and the sliding base. This avoids designing a customized sliding base for each type of controller and reduces tooling development costs.

[0032] Furthermore, the power assembly includes a rotary clamping cylinder, the piston of which is fixedly connected to the clamping component. The rotary clamping cylinder integrates rotary and linear motion functions, eliminating the need for an additional rotary motor or reversing mechanism. Before clamping, the cylinder can drive the clamping component to rotate to a specific angle, avoiding the area above the positioning groove, facilitating the placement and removal of the controller under test. When testing is required, it can also control the clamping component to limit the vertical movement of the controller under test.

[0033] Furthermore, the sliding base is also equipped with wiring terminals, including a first wiring strip and a second wiring strip. The first wiring strip is electrically connected to the test connector. This connection allows electrical signals (such as power signals, CAN bus signals, etc.) collected by the test connector to be centrally transmitted to the second wiring strip via a fixed line, avoiding contact confusion or loosening caused by multiple cables directly connecting to the test connector. The second wiring strip supports direct plugging and unplugging or screw crimping of cables from external testing equipment (such as oscilloscopes and power modules), enabling wiring connections without soldering and significantly reducing pre-test wiring preparation time.

Detailed Implementation

[0040] A controller testing device, comprising:

[0041] 100 racks;

[0042] A mounting base 200 is replaceably mounted on the frame 100. The mounting base 200 is provided with a positioning groove 210 adapted to the controller under test 500. The mounting base 200 is connected to the frame 100 via a quick-change positioning assembly.

[0043] The clamping mechanism 300 includes a power assembly 310 fixed to the frame 100 and a clamping member 320 connected to the output end of the power assembly 310. The clamping member 320 is disposed above the positioning groove 210.

[0044] The sliding test mechanism 400 includes a sliding seat 410, a test connector 420 detachably mounted on the sliding seat 410, and a drive assembly 430. The sliding seat 410 is slidably connected to the frame 100 through a sliding guide assembly 440. The drive assembly 430 is drively connected to the sliding seat 410 and controls its movement so that the test connector 420 is aligned and connected with the controller under test 500.

[0045] The mounting base 200 is equipped with a positioning groove 210 adapted to the controller under test 500, enabling rapid and accurate positioning of the controller and ensuring the alignment accuracy between the test interface and the test connector 420. The quick-change positioning assembly supports rapid replacement of the mounting base 200, meeting the testing needs of different controller models, reducing changeover time, and improving production line flexibility. The clamping mechanism 300 drives the clamping component 320 via a power component 310. The clamping component 320 is positioned above the positioning groove 210, automatically clamping and fixing the controller, ensuring stable controller position during testing and reducing the risk of poor contact. The sliding test mechanism 400 controls the movement of the sliding base 410 via a drive component 430, achieving automatic alignment and connection between the test connector 420 and the controller interface, replacing manual insertion and removal operations, significantly improving testing efficiency, reducing worker workload, and ensuring that the force applied when the test connector 420 is inserted into the controller under test 500 is uniform and controllable, preventing damage to the controller under test 500 when the test probe is inserted. The sliding guide assembly 440 ensures that the sliding seat 410 moves smoothly and accurately, avoiding damage caused by collision between the test connector 420 and the interface, and improving test reliability.

[0046] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0048] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0050] See Figures 1 to 4 This invention provides an embodiment of a controller testing device. The device includes a frame 100, along whose length a sliding testing mechanism 400, a fixed base 200, and a clamping mechanism 300 are sequentially arranged. The sliding testing mechanism 400 mainly includes a sliding base 410, a driving assembly 430, and a test connector 420 detachably mounted on the sliding base 410. The driving assembly 430 drives the sliding base 410 to move with the test connector 420, facilitating the insertion or removal of the controller under test 500. A guide assembly is provided on the frame 100 to further improve the accuracy of the sliding direction of the sliding base 410, ensuring that the test connector 420 can be aligned with the test interface of the controller under test 500 for insertion. Since the test connector 420 is detachably mounted on the sliding base 410, the corresponding test connector 420 can be installed according to the model of the controller under test 500 without requiring major modifications to the overall structure of the controller testing device.

[0051] The mounting base 200 is replaceably mounted on the frame 100. The mounting base 200 has a positioning groove 210 adapted to the test controller. The opening of the positioning groove 210 faces upwards, and the controller under test 500 is installed from above within the positioning groove 210 of the mounting base 200. The positioning groove 210 can limit the horizontal movement of the controller under test 500. The mounting base 200 and the frame 100 are connected by a quick-change positioning assembly. This assembly not only fixes the relative position of the frame 100 and the mounting base 200 but also allows for quick replacement of the mounting base 200 to accommodate different controller models.

[0052] The clamping mechanism 300 is mainly used to limit the vertical direction of the controller 500 under test after it is placed in the positioning groove 210 of the fixing seat 200. The clamping mechanism 300 includes a power component 310 fixed to the frame 100 and a clamping member 320 connected to the output end of the power component 310. The clamping member 320 is disposed above the positioning groove 210. The power component 310 drives the clamping member 320 to move at least in the vertical direction, so that the clamping member 320 can limit the vertical direction of the controller 500 under test when testing is required.

[0053] Furthermore, the sliding guide assembly 440 includes a slide rail 441 and a slider 442. The slide rail 441 is fixed to the frame 100 and is arranged along the length direction. The sliding seat 410 slides in cooperation with the slide rail 441 through the slider 442, thereby ensuring that the sliding seat 410 can slide along the length direction of the frame 100. In this embodiment, two sets of sliding guide assemblies 440 are provided, located on the left and right sides of the sliding seat 410 respectively, which can completely eliminate the lateral offset of the sliding seat 410 and avoid tilting and misalignment when the sliding seat 410 is subjected to force on one side.

[0054] In this embodiment, the drive assembly 430 includes a servo motor 431, a threaded lead screw 432, and a nut 433. The lead screw 432 is rotatably connected to the frame 100. For example, bearing seats with bearings are connected to both ends of the lead screw 432, and the bearing seats are fixed to the frame 100. This ensures the stability of the lead screw 432 during rotation. The lead screw 432 is arranged along the length of the frame 100 and is threadedly engaged with the nut 433 fixed to the bottom of the sliding seat 410. The servo motor 431 drives the lead screw 432 to rotate through a transmission component. When the lead screw 432 rotates, the nut 433 can drive the sliding seat 410 to move along the length of the lead screw 432, thereby controlling the insertion or removal of the test connector 420 from the controller under test 500. The threaded engagement between the lead screw 432 and the nut 433 has precise transmission characteristics. Through the precise control of the servo motor 431, the displacement accuracy of the sliding seat 410 at the micrometer level can be achieved. For example, when the test connector 420 needs to be precisely aligned with the controller interface (such as when the spacing of the CAN bus interface is only in the millimeter range), the high positioning accuracy of the lead screw 432 drive can avoid contact deviations caused by overshoot or insufficient displacement, ensuring reliable electrical connection. The backlash of the threaded drive can be further eliminated through preload design (such as double nut 433 backlash elimination), reducing backlash error and improving the repeatability and stability of the test process.

[0055] The closed-loop control characteristics of the servo motor 431 can monitor and adjust the moving speed, acceleration, and position of the slide block 410 in real time. For example, when the test connector 420 approaches the controller interface, the moving speed can be reduced through program settings to achieve a "slow and light touch" flexible docking, avoiding rigid collisions that could damage the interface; it can also quickly retract upon disengagement, improving testing efficiency. Compared to pneumatic or belt drives, the motion trajectory of the lead screw 432 is easier to program precisely through a servo system, making it suitable for automated control of complex testing processes (such as multi-stage step-by-step testing).

[0056] Furthermore, the transmission components include a synchronous belt 434 and a synchronous pulley 435 connected to the lead screw 432. The servo motor 431 drives the synchronous pulley 435 to rotate via the synchronous belt 434. That is, synchronous pulleys 435 are provided at both the motor shaft of the servo motor 431 and the end of the lead screw 432. The two synchronous pulleys 435 are connected by the synchronous belt 434. The meshing transmission between the synchronous belt 434 and the synchronous pulley 435 achieves slip-free transmission through tooth profile matching, avoiding the slippage phenomenon of traditional belt drives. This ensures that the rotational speed of the servo motor 431 is accurately transmitted to the lead screw 432, maintaining the uniformity of the sliding seat 410's movement speed. For example, when the test connector 420 approaches the controller interface, the smooth transmission can avoid interface collisions caused by speed fluctuations, which is especially suitable for testing precision signal interfaces (such as high-frequency communication terminals) that are sensitive to impact. The elastic material (such as rubber or polyurethane) of the synchronous belt 434 can absorb minor vibrations during transmission, further reducing the vibration of the sliding seat 410 and improving the stability of the test docking.

[0057] Based on the above embodiments, the test connector 420 and the sliding seat 410 are connected by a plug-in quick-change structure. This plug-in quick-change structure includes corresponding insertion holes 450 on the sliding seat 410 and the test connector 420, and a connector 460 that can be detachably inserted into the insertion holes 450. Specifically, insertion holes 450 are provided at corresponding positions on both the test connector 420 and the sliding seat 410. The connector 460 is inserted into the insertion holes 450 to fix the relative positions of the test connector 420 and the sliding seat 410. The connector 460 can be a rod or a bolt. The insertion holes 450 are generally located symmetrically on the left and right sides of the test connector 420 along the sliding direction, which better fixes the positions of the sliding seat 410 and the test connector 420, preventing the test connector 420 from deflecting when subjected to the reaction force of the controller under test 500. The plug-in quick-change structure achieves fixation through direct insertion of the insertion holes 450 and the connector 460, eliminating the need for screwdrivers, wrenches, or other tools. Operators can complete the disassembly or installation of the test connector 420 within 10 seconds. For example, when switching between different types of controller interfaces or testing different models of the controller under test 500, the corresponding test connector 420 can be quickly replaced, avoiding the time-consuming problem of unscrewing and unscrewing screws one by one in the traditional screw fixing method. The standardized socket 450 design makes the test connectors 420 interchangeable for different functions or models, adapting to the needs of multi-station parallel testing or rapid switching of test items on the production line.

[0058] Furthermore, the slide base 410 is provided with multiple sets of sockets 450. The position of the socket 450 of the test connector 420 matches the specific set of sockets 450 on the slide base 410. That is, the sockets 450 on different models of test connectors 420 match the corresponding set of sockets 450 on the slide base 410, thereby allowing the slide base 410 to adapt to more different models of test connectors 420 and reduce tooling development costs.

[0059] Based on the above embodiments, the sliding base 410 is further provided with a terminal block 470, which includes a first terminal block and a second terminal block. The corresponding terminals on the first terminal block and the corresponding terminals on the second terminal block are electrically connected. The first terminal block is electrically connected to the test connector 420. Electrical signals (such as power signals, CAN bus signals, etc.) collected by the test connector 420 can be centrally transmitted to the second terminal block via a fixed line, avoiding contact confusion or loosening caused by multiple cables being directly connected to the test connector 420. The second terminal block supports direct plugging and unplugging or screw crimping of cables from external test equipment (such as oscilloscopes, power modules), completing the wiring connection without soldering, significantly shortening the wiring preparation time before testing.

[0060] Based on the above embodiments, the quick-change positioning assembly for the fixed base 200 and the frame 100 includes a mutually interlocking positioning structure disposed between the frame 100 and the fixed base 200. This mutually interlocking positioning structure constrains the displacement of the fixed base 200 in the horizontal direction, preventing the fixed base 200 from shifting horizontally relative to the frame 100. The mutually interlocking positioning structure achieves rapid alignment between the fixed base 200 and the frame 100 through the geometric constraints of the mechanical structure.

[0061] Specifically, the interlocking positioning structure includes the cooperation of a protrusion 110 and a recess 220. The protrusion 110 can be any of a cylindrical, conical, or blocky geometric shape, and the recess 220 is adapted to the shape of the protrusion 110. Cylindrical protrusions: suitable for circular positioning holes, providing stable circumferential constraints, commonly used for single-point positioning of small and medium-sized fixing seats 200; Conical protrusions: have an automatic centering function, and can quickly correct positional deviations through conical guidance during insertion, suitable for scenarios requiring rapid blind insertion; Blocky protrusions: have a large contact area and strong load-bearing capacity, can withstand large vertical loads, and prevent the interlocking structure from deforming due to overload. In this embodiment, the protrusion 110 is cylindrical and fixed on the frame 100, and the recess 220 is a circular hole located at the bottom of the fixing seat 200. During assembly, simply align the circular hole at the bottom of the fixing seat 200 with the cylinder on the frame 100 and insert it. By limiting the geometry of the interlocking structure, the quick-change positioning component can ensure structural strength and positioning accuracy while also being flexible and economical, making it particularly suitable for controller automation testing scenarios that require both "quick changeover" and "stable testing".

[0062] In this embodiment, the power component 310 of the clamping mechanism 300 includes a rotary clamping cylinder. The piston of the rotary clamping cylinder is fixedly connected to the clamping member 320. The rotary clamping cylinder can not only drive the clamping member 320 to move vertically up and down to limit the vertical movement of the controller under test 500 installed in the fixed base 200, but also rotate a certain angle in the horizontal plane. This allows the space above the controller under test 500 to be cleared when installing or removing the controller under test 500, making it easier to install and remove the controller under test 500. In fact, the movement trajectory of the clamping member 320 driven by the rotary clamping cylinder is spiral upward or spiral downward. The rotary clamping cylinder integrates rotary and linear motion functions, eliminating the need for an additional rotary motor or reversing mechanism. It occupies more than 50% less space than the traditional "motor + coupling + lead screw 432" clamping structure. This feature allows the clamping mechanism 300 to be compactly arranged on the top of the frame 100, making it particularly suitable for miniaturized testing devices or production lines with multiple workstations arranged in parallel, facilitating equipment miniaturization design.

[0063] When testing is required, select a suitable test connector 420 according to the model of the controller under test 500. Place the test connector 420 on the sliding base 410, aligning the socket 450 of the test connector 420 with the corresponding socket 450 on the sliding base 410. Insert the connector 460 through the socket 450 of the test connector 420 into the socket 450 of the sliding base 410 to complete the installation of the test connector 420. Then, connect the test leads of the test connector 420 to the first terminal block of the terminal block 470. The second terminal block of the terminal block 470 is connected to the testing instrument via connecting wires. Next, select a suitable mounting base 200. The mounting base 200 has a positioning groove 210 that matches the size of the controller under test 500. Place the mounting base 200 in the designated position on the frame 100, so that the recessed part 220 at the bottom of the mounting base 200 engages with the protrusion 110 on the frame 100, completing the quick positioning and installation of the mounting base. This completes the assembly of the entire control testing device. At the start of the test, the controller under test (DUT) 500 is placed in the positioning groove 210. The test device is activated, and the power component 310 drives the clamping component 320 to press down on the top surface of the DUT 500, thereby fixing the relative position of the DUT 500 and ensuring that the DUT 500 does not wobble. The servo motor 431 starts, driving the screw to rotate. The nut 433, which cooperates with the screw, drives the sliding seat 410 to move towards the DUT 500. Once the test connector 420 is inserted into the socket 450 of the DUT 500, the servo motor 431 stops running, and the test of the DUT 500 begins. After the test is completed, the above steps are reversed to remove the DUT 500 and insert a new DUT 500. This technical solution, through the deep integration of automated mechanical structure, precision transmission system, and modular quick-change design, systematically solves the problems of low efficiency, poor accuracy, and insufficient compatibility of traditional manual testing, while also achieving breakthroughs in cost control and maintenance convenience. Its core value lies in building a "highly efficient, flexible, accurate, reliable, and future-adaptable" controller testing platform, which can be widely used in controller mass production testing and R&D verification scenarios in fields such as automotive electronics, industrial automation, and aerospace.

[0064] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
