Description

Technical Field

[0001] This utility model relates to the field of electronic equipment testing technology, and specifically to a magnetic aging rack. Background Technology

[0002] Traditional aging racks typically employ fixed or bolted positioning structures, which are highly dependent on the size and model of the components under test. When testing components of different specifications, frequent disassembly and replacement of the positioning modules are required, which is cumbersome and time-consuming, especially in scenarios involving the testing of multiple component models, resulting in low efficiency. Utility Model Content

[0003] To overcome at least one of the aforementioned drawbacks, this utility model provides a magnetic aging rack. The objective of this utility model can be achieved by employing the following technical solution:

[0004] This application provides a magnetic aging rack, comprising:

[0005] A vertical frame, on which a magnetically conductive substrate is provided;

[0006] Multiple positioning modules are provided, which are detachably attached to the front and / or back of the magnetic substrate. Each positioning module is provided with multiple movable plug-in modules for fixing the component under test.

[0007] In one possible implementation, the plug-in modules are distributed in rows and columns on different positioning modules to form an array-type fixed structure that matches the component under test.

[0008] In one possible implementation, the positioning module includes:

[0009] guide;

[0010] A magnetic attraction element is disposed on the side of the guide rail facing the magnetically conductive substrate, for forming a detachable magnetic connection with the magnetically conductive substrate.

[0011] In one possible implementation, the plug-in module includes:

[0012] A plug-in base, which can slide along the length of the positioning module and can be fixed at a preset position of the positioning module;

[0013] A plug-in component is disposed on the side of the plug-in base opposite to the magnetic substrate, and is used to form an electrical connection with the component under test.

[0014] In one possible implementation, the orientation of the plug-in component is adjustable.

[0015] In one possible implementation, the back of the plug-in base is provided with a horizontal position positioning groove and a vertical position positioning groove, and the plug-in component is connected to the plug-in base by the horizontal position positioning groove and the vertical position positioning groove.

[0016] In one possible implementation, there are multiple horizontal pose positioning slots and multiple vertical pose positioning slots, with the multiple horizontal pose positioning slots arranged in the horizontal direction and the multiple vertical pose positioning slots arranged in the vertical direction.

[0017] In one possible implementation, the vertical frame is further provided with a power supply module and a signal module;

[0018] The number of plugs for forming an electrical connection with the device under test is at least two;

[0019] The power module is electrically connected to one of at least two of the plug-in components to provide power to the device under test.

[0020] The signal module is electrically connected to at least two of the plug-in components that are different from the one connected to the power module, for transmitting test signals to the device under test or receiving signals fed back by the device under test.

[0021] In one possible implementation, the bottom of the vertical frame is provided with sliding wheels to allow the magnetic aging rack to be moved.

[0022] In one possible implementation, the top of the vertical frame is provided with guide wheels, which are used to cooperate with guide strips to guide the movement direction of the magnetic aging rack.

[0023] The beneficial technical effects of this utility model are as follows: According to this disclosure, the positioning module in the magnetic aging rack is magnetically attached to the magnetic substrate, allowing for tool-free installation and removal. Compared to traditional bolt connections, this shortens the replacement time per cycle, making it particularly suitable for frequent adjustments required in scenarios involving mixed testing of multiple device-under-test (DUT) models. Furthermore, the positioning module can be attached to both the front and back of the magnetic substrate, enabling bidirectional utilization of the three-dimensional space. This allows for more testing stations to be accommodated within the same floor area, improving the efficiency of the aging rack. Additionally, the plug-in modules on the positioning module support position adjustment, allowing for flexible layout changes based on the size, pin spacing, and other parameters of the DUT. This eliminates the need to replace the entire positioning module, adapting to various component specifications and reducing hardware waste caused by model switching. Moreover, the detachable positioning module and its plug-in modules support standardized production, allowing users to pre-configure multiple sets of different types of modules for quick replacement during testing, enabling mixed testing of multiple DUT models.

[0029] In the following detailed disclosure, these embodiments are fully described with reference to the accompanying drawings. In order to enable those skilled in the art to understand and clarify the technical solution of this utility model more clearly, the embodiments described below are not limited thereto. The present utility model will be further described in detail below with reference to the embodiments and the accompanying drawings.

[0031] In the description of this utility model, it should be understood that the terms "upper", "lower", "left", "right", "front", "rear", etc., indicate the orientation or positional relationship based on the orientation or positional relationship 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 unit 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.

[0032] See Figure 1 and Figure 2 As shown, this application provides a magnetic aging rack, including a vertical frame 1 and multiple positioning modules 3; the vertical frame 1 is provided with a magnetic conductive substrate 2; the multiple positioning modules 3 are detachably adsorbed onto the front and / or back of the magnetic conductive substrate 2, and each positioning module 3 is provided with multiple movable plug-in modules 4, the plug-in modules 4 being used to fix the component under test 5.

[0033] The magnetic aging rack provided in this embodiment has a positioning module 3 that is magnetically attached to the magnetic substrate 2. It can be installed or disassembled without tools. Compared with the traditional bolt connection method, the time for a single replacement can be shortened by more than 80%, which is especially suitable for frequent adjustment needs in scenarios where multiple models of test components 5 are tested together.

[0034] The magnetic aging rack provided in this embodiment can have the positioning module 3 attached to both the front and back of the magnetic substrate 2, realizing bidirectional utilization of three-dimensional space. It can accommodate more test stations in the same floor area, improving the efficiency of the aging rack.

[0035] The magnetic aging rack provided in this embodiment has a plug-in module 4 on the positioning module 3 that supports position adjustment. The layout can be flexibly changed according to the size, pin spacing and other parameters of the component under test 5. It can adapt to various specifications of components without replacing the entire positioning module 3, reducing hardware waste caused by model switching.

[0036] The magnetic aging rack provided in this embodiment, with its detachable positioning module 3 and plug-in module 4, supports standardized production. Users can pre-configure multiple sets of different types of modules and quickly replace them as needed during testing to achieve mixed testing of multiple models of components under test 5.

[0037] The vertical frame 1 serves as the main support for the entire aging rack, providing mechanical structural stability. It is typically constructed by welding or assembling metal profiles (such as aluminum or steel). In this embodiment, the vertical frame 1 is a rectangular column structure, consisting of two vertical columns and two horizontal beams forming a "door frame" shape.

[0038] The magnetically conductive substrate 2 is fixed within the plane enclosed by two columns and two crossbeams. It can be made of a magnetically conductive material (such as iron, low-carbon steel, or silicon steel sheet) to ensure good magnetic permeability and guarantee that the positioning module 3 is firmly attracted by magnetic force. In some specific examples, the magnetically conductive substrate 2 is a single-plate structure, with the width matching the column spacing and the height matching the crossbeam spacing. In other specific examples, the magnetically conductive substrate 2 is a structure of multiple elongated strips, composed of parallel elongated magnetically conductive plates, with the direction of the strips aligned with the columns or crossbeams of the vertical frame 1. In this embodiment, the magnetically conductive substrate 2 is composed of parallel elongated magnetically conductive plates, with multiple elongated magnetically conductive plates spaced apart along the height direction of the columns.

[0039] The positioning module 3 serves as an intermediate carrier connecting the magnetic substrate 2 and the component under test 5, supporting the insertion module 4 to position and fix the component under test 5. In this embodiment, the positioning module 3 is magnetically attracted to the magnetic substrate 2. Furthermore, the magnetic force can be switched on and off via an electronic switch, further improving the ease of disassembly.

[0040] In this design, the plug-in module 4 directly contacts the component under test (DUT) 5, and uses a mechanical structure to fix the pins or body of the DUT 5, ensuring a stable electrical connection during testing. In some specific examples, the DUT 5 is a circuit board, which can be stably connected using a single plug-in module 4. In other specific examples, the DUT 5 is an LED display module, which needs to meet both power input and signal control requirements. Furthermore, some LED display modules are large in size and have widely distributed pins; therefore, two plug-in modules 4 are used for collaborative connection.

[0041] It is understandable that when the component under test (DUT) 5 needs to simultaneously meet power input and signal control requirements, and two plug-in modules 4 are used for collaborative connection, the two plug-in modules 4 connecting to the same DUT 5 are located on the same positioning module 3, or the two plug-in modules 4 connecting to the same DUT 5 are located on two adjacent positioning modules 3. In this embodiment, the DUT 5 is an LED display module, and the two plug-in modules 4 connecting to the same LED display module are located on two adjacent positioning modules 3. At this time, since the interval between the two adjacent positioning modules 3 is adjustable, and the position of the plug-in modules 4 on the positioning modules 3 is also adjustable, it can adapt to the interface spacing of LED display modules of different specifications.

[0042] In one possible implementation, see Figure 1 As shown, the plug-in module 4 is distributed in rows and columns on different positioning modules 3 to form an array-type fixed structure that matches the component under test 5.

[0043] The magnetic aging rack provided in this embodiment has a standardized layout of rows and columns. When the component under test 5 is connected by two plug-in modules 4, and the two plug-in modules 4 are located on two adjacent positioning modules 3, when the spacing of a certain group of plug-in modules 4 needs to be adjusted, the spacing of the other groups can be changed synchronously and regularly through the row and column array. There is no need to adjust each plug-in module 4 one by one, which improves the adjustment efficiency in multi-module collaborative testing scenarios. It is especially suitable for mixed testing needs that require frequent switching of the component under test 5 model and quick adaptation to different interface spacings.

[0044] In the horizontal direction (lateral direction), the plug-in modules 4 of different positioning modules 3 are aligned at the same height, forming a horizontally arranged "row".

[0045] In the vertical direction (longitudinal direction), the plug-in modules 4 of different positioning modules 3 are aligned at the same position to form a "column" arranged vertically.

[0046] It is understandable that the positions of all plug-in modules 4 follow a standardized row and column grid layout, the spacing between modules in the same row / column is consistent, and the plug-in modules 4 that cross positioning modules 3 (such as adjacent positioning modules 3) are aligned in the row and column directions.

[0047] In one possible implementation, see Figure 2 As shown, the positioning module 3 includes a guide rail 31 and a magnetic element 32; the magnetic element 32 is disposed on the side of the guide rail 31 facing the magnetic substrate 2, and is used to form a detachable magnetic connection with the magnetic substrate 2.

[0048] The guide rail 31 is generally a long strip structure (such as a metal slide rail, a plastic guide rail 31, etc.), and its surface is provided with a sliding groove or a slot for installing the plug-in module 4.

[0049] The magnetic element 32 is fixed to the back of the guide rail 31 (i.e., the side of the guide rail 31 that contacts the magnetic substrate 2). When the guide rail 31 approaches the magnetic substrate 2, the magnetic element 32 is magnetically attracted to the magnetic substrate 2, forming a strong mechanical connection. Furthermore, to improve connection stability, multiple magnetic elements 32 can be provided. In this embodiment, three magnetic elements 32 are provided, with the three magnetic units arranged along the length of the guide rail 31 and corresponding one-to-one with the three elongated magnetic plates constituting the magnetic substrate 2.

[0050] Understandably, in order to improve the adjustment efficiency of the positioning module 3, the magnetic element 32 can adopt a switchable magnetic base, which can instantly switch between adsorption and release states by means of the switch of the magnetic base (such as a knob or electronic control button).

[0051] In one possible implementation, see Figure 2 As shown, the plug-in module 4 includes a plug-in base 41 and a plug-in component 42; the plug-in base 41 can slide along the length direction of the positioning module 3 and can be fixed in a preset position of the positioning module 3; the plug-in component 42 is disposed on the side of the plug-in base 41 facing away from the magnetic substrate 2, and is used to form an electrical connection with the component under test 5.

[0052] The insertion base 41 can be a spring-loaded base consisting of a base body, a spring, and a latch (or claw). The base body supports the insertion component 42, and a spring and a latch are installed on the side that contacts the guide rail 31. The spring can be a compression spring, with one end fixed to the base body and the other end connected to the latch. The latch is the component that directly contacts the guide rail 31, and its surface can be provided with teeth or protrusions to increase friction. In practical applications, when the position of the insertion module 4 needs to be adjusted, the button or knob can be manually operated to compress the spring, causing the latch to separate from the guide rail 31, allowing the base body to move the insertion component 42 freely on the guide rail 31. When the insertion module 4 moves to the preset position, the button or knob is released, and the spring extends to push the latch to press against the surface of the guide rail 31, using static friction to lock the position and ensure no displacement during testing, thus achieving the purpose of fixing the insertion component in the preset position.

[0053] The connector can be a plug-type connection assembly, which achieves the fixation and electrical connection of the component under test 5 through the mechanical cooperation and electrical contact between the male and female ports.

[0054] It is understood that in this embodiment, the position adjustment method of the plug-in is as follows: the magnetic attraction position of the adjacent positioning module 3 can be moved up and down along the magnetic substrate 2 to adjust the horizontal spacing; the plug-in base 41 on each positioning module 3 slides along the guide rail 31 to adjust the vertical spacing; through the row and column array rules, it is ensured that the plug-in across modules is aligned in the horizontal / vertical direction, realizing "synchronous linkage adjustment" and avoiding the tediousness of debugging one by one.

[0055] In one possible implementation, see Figure 2 As shown, the orientation of the plug-in component 42 is adjustable.

[0056] The magnetic aging rack provided in this embodiment has an adjustable plug-in component 42, which can be precisely matched with the interface of the component under test 5, avoiding connection failure or poor contact caused by incompatible interface orientations, and expanding the aging rack's adaptability to different types of components under test 5.

[0057] In one possible implementation, see Figure 2 As shown, the back of the plug-in base 41 is provided with a horizontal position positioning groove 411 and a vertical position positioning groove 412. The plug-in component 42 is connected to the plug-in base 41 by the horizontal position positioning groove 411 and the vertical position positioning groove 412.

[0058] Among them, the horizontal pose positioning slot 411 is a transverse slot, and the vertical pose positioning slot 412 is a longitudinal slot. The transverse slot and the longitudinal slot are perpendicular to each other, forming a "cross-shaped" positioning structure.

[0059] The back of the plug-in component 42 (on the side connected to the plug-in base 41) is provided with a snap-fit ​​protrusion, which is usually a symmetrically distributed elastic claw or wedge-shaped protrusion, and can engage with the horizontal position positioning groove 411 or the vertical position positioning groove 412.

[0060] Understandably, the reversal steps of the plug-in component 42 are as follows: unlock the current posture, manually press the buckle protrusions on both sides of the plug-in component 42 to make it elastically deform and disengage from the current posture positioning groove; rotate the plug-in component 42 to rotate the entire plug-in component 42 by 90° so that the buckle protrusion in the original horizontal direction is aligned with the vertical posture positioning groove 412 (or vice versa); lock the new posture, push the plug-in component 42 to make the buckle protrusion engage with the positioning groove in the new direction, and use the mechanical limit of the groove to fix the posture.

[0061] In one possible implementation, see Figure 2As shown, there are multiple horizontal pose positioning slots 411 and multiple vertical pose positioning slots 412. The multiple horizontal pose positioning slots 411 are arranged in the horizontal direction, and the multiple vertical pose positioning slots 412 are arranged in the vertical direction.

[0062] Multiple horizontal positioning slots 411 are arranged at equal intervals along a direction perpendicular to the guide rail 31, forming multiple transverse slots. These transverse slots correspond to different installation positions of the plug-in component 42 in the horizontal direction (such as left, center, and right).

[0063] Multiple vertical positioning slots 412 are arranged at equal intervals along the extension direction of the guide rail 31, forming multiple longitudinal slots. The multiple longitudinal slots correspond to different installation positions of the plug-in component 42 in the vertical direction (such as upper, middle, and lower).

[0064] Understandably, by selecting different horizontal pose positioning slots 411, the lateral position of the plug-in component 42 can be finely adjusted to accommodate the horizontal spacing differences of the interface of the component under test 5. By selecting different vertical pose positioning slots 412, the longitudinal height of the plug-in component 42 can be finely adjusted to accommodate the vertical height differences of the interface of the component under test 5.

[0065] In one possible implementation, see Figure 1 As shown, the vertical frame 1 is also provided with a power supply module 6 and a signal module; there are at least two plug-in components 42 for forming an electrical connection with the device under test 5; the power supply module 6 is electrically connected to one of the at least two plug-in components 42 for providing power to the device under test 5; the signal module is electrically connected to another of the at least two plug-in components 42 that is not connected to the power supply module 6, for transmitting test signals to the device under test 5 or receiving signals fed back by the device under test 5.

[0066] In this embodiment, the power supply module 6 consists of sixteen power supply modules. When the vertical frame 1 is a "door frame" shaped frame composed of two vertical columns and two horizontal beams, multiple power supply modules are fixedly installed on the horizontal beam at the top of the vertical frame 1.

[0067] In this embodiment, the signal module includes a transmitting card and an adapter card. When the vertical frame 1 is a "door frame" shaped frame consisting of two vertical columns and two horizontal beams, multiple power supply modules are fixedly installed on the horizontal beams at the bottom of the vertical frame 1.

[0068] Understandably, for scenarios where the component under test 5 requires dual interfaces, such as an LED display module that needs to simultaneously meet the requirements of power input and signal control: one plug-in 42 connects to the power module 6 to provide power to the LED module; the other plug-in 42 connects to the signal module to transmit display signals (such as image data, brightness adjustment commands, etc.) or receive status feedback from the LED display module (such as fault signals).

[0069] In one possible implementation, see Figure 1 As shown, the bottom of the vertical frame 1 is equipped with sliding wheels 7, which are used to make the magnetic aging rack movable.

[0070] In this embodiment, when the vertical frame 1 is a "door frame" shaped frame consisting of two vertical columns and two horizontal beams, the bottom ends of the two vertical columns are connected to the horizontal beams, and then continue to extend downwards and connect to the sliding wheels 7. Thus, the aging rack can move between different areas according to testing needs (e.g., from test area A to test area B), avoiding space waste caused by fixed installation.

[0071] In one possible implementation, see Figure 1 As shown, the top of the vertical frame 1 is provided with guide wheels 8, which are used to cooperate with guide strips 9 to guide the movement direction of the magnetic aging rack.

[0072] In this embodiment, when the vertical frame 1 is a "door frame" shaped frame consisting of two vertical columns and two horizontal beams, the tops of the two vertical columns are connected to the horizontal beams and then continue to extend upwards and connect with the guide wheel 8.

[0073] The guide wheel 8 is mounted on the extension section at the top of the vertical frame 1 via bearings or pins, with the center of the wheel surface aligned with the central axis of the guide bar 9. The extension direction of the guide bar 9 is the preset movement path of the aging rack. The guide wheel 8 moves along the guide bar 9 through rolling friction, ensuring that the movement trajectory of the aging rack is completely consistent with that of the guide bar 9. When the guide wheel 8 moves along the guide bar 9, the wheel flange contacts the side wall of the groove in the guide bar 9.
