Description

Technical Field

[0001] This utility model relates to the field of wireless module testing, specifically to an automated wireless module testing device. Background Technology

[0002] Wireless modules are a crucial link connecting the sensing layer and network layer of the Internet of Things (IoT). As a low-level hardware component, they are irreplaceable and serve as the carrier for IoT smart terminals to connect to the network and be located. Wireless modules are categorized into communication modules and positioning modules based on their network connectivity and positioning capabilities. Positioning modules primarily utilize GNSS satellite positioning, while communication modules are classified into cellular and non-cellular types based on different communication technologies. Wireless modules must be tested before use, and only those that pass the tests can be deployed.

[0003] According to Chinese Patent No. CN219946111U, an automated wireless module testing device is disclosed. In this utility model, two connecting columns drive two sliding plates to move towards the center, which can effectively reduce the vibration generated during the test frame test. The two sliding columns further reinforce the fixing plate, which can effectively fix the wireless module, prevent vibration during the test, and also effectively reduce noise, which is beneficial to physical and mental health. The limiting seat prevents the sliding plate from sliding out of the first guide rail.

[0004] Regarding the aforementioned patent content, by setting up structures such as threaded rods and pressure plates, after the wireless module is placed on the test frame, the threaded rod is rotated to move downwards, causing the pressure plate to move downwards as well, so that the pressure plate presses down on the wireless module, thereby limiting the wireless module. However, when the pressure plate moves downwards excessively, the pressure plate will exert a large squeezing force on the wireless module for a long time, which can easily cause damage to the wireless module and reduce the pressing efficiency of the pressure plate on the wireless module. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide an automated wireless module testing device to solve the technical problem that excessive pressure on the wireless module when the pressure plate moves too much can easily damage the wireless module.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated wireless module testing device, comprising a workbench and a lifting plate. A display, a host computer, and a testing fixture are respectively placed on the top of the workbench. Frames are bolted to both sides of the top of the lifting plate. Springs are installed inside the frames, and the bottom ends of the springs are connected to movable blocks. A pressure rod penetrating the lifting plate is installed at the bottom of the movable block. A threaded hole is opened at the bottom end of the pressure rod, and a threaded post is threadedly connected inside the threaded hole. An installation plate is installed at the bottom end of the threaded post, and an anti-slip pad is installed at the bottom of the installation plate.

[0007] By adopting the above technical solution, the anti-slip pad prevents the bottom of the pressure rod from directly contacting the wireless module, thus protecting the wireless module. At the same time, the pressure rod can hold down the wireless module, improving its stability.

[0008] Furthermore, a test platform is mounted on the top of the test fixture, and two placement slots are provided on the top of the test platform. A support frame is also mounted on the top of the test fixture.

[0009] By adopting the above technical solution, the placement slot makes it convenient for staff to place the wireless module inside, thereby enabling the testing of the wireless module.

[0010] Furthermore, the support frame is provided with a threaded rod, and the bottom end of the threaded rod is connected to a lifting plate via a bearing.

[0011] By adopting the above technical solution, the movement of the threaded rod will drive the lifting plate to move, which in turn will drive the pressure rod to move, so as to adjust the height of the pressure rod.

[0012] Furthermore, a rotating handle is installed at the top of the threaded rod, and support seats are installed on both sides of the bottom of the worktable.

[0013] By adopting the above technical solution, it is convenient for workers to rotate the threaded rod through the handle, and the support seat can support the workbench.

[0014] Furthermore, a guide rod is installed between the support frame and the test fixture, the guide rod passes through the lifting plate, and the lifting plate is slidably connected to the guide rod.

[0015] By adopting the above technical solution, the guide rod can guide the lifting plate and improve the stability of the lifting plate when it moves.

[0016] Furthermore, the test fixture is connected to two first data lines, the host computer is connected to the test fixture via a second data line, and the display is connected to the host computer via a cable.

[0017] By adopting the above technical solution, it is convenient to test modules that do not need to be used.

[0018] Furthermore, the pressure bar is located directly above the placement slot.

[0019] By adopting the above technical solution, the wireless module placed in the placement slot can be pressed down when the pressure rod moves down.

[0020] Furthermore, the threaded rod is threadedly connected to the support frame.

[0021] By adopting the above technical solution, the threaded rod can move when rotated.

[0022] Furthermore, both the anti-slip pad and the mounting plate are detachably connected via threaded posts and threaded holes, and the anti-slip pad is made of rubber material.

[0023] By adopting the above technical solution, the anti-slip mat and the mounting plate can be disassembled and replaced.

[0024] Furthermore, the movable block is slidably connected to the frame, and the spring is made of stainless steel.

[0025] By adopting the above technical solution, the movable block can slide inside the frame, thereby improving the stability of the movable block when it moves.

[0026] In summary, the present invention has the following main advantages:

[0027] 1. This utility model, by setting up a frame, a movable block, a spring, and a pressure rod, allows the operator to rotate a threaded rod when the wireless module needs to be pressed and limited. This causes the threaded rod to move downward, which in turn moves the lifting plate downward, and then moves the pressure rod downward. The anti-slip pad first contacts the wireless module, and as the lifting plate continues to move downward, the anti-slip pad deforms while the movable block compresses the spring, thus providing cushioning and preventing the pressure rod from moving too downward and causing damage to the wireless module. This improves the protection of the wireless module, while the pressure rod can hold the wireless module in place, improving its stability.

[0028] 2. This utility model, by providing an anti-slip pad, avoids direct contact between the bottom end of the pressure rod and the wireless module, thereby protecting the wireless module and preventing wear on the pressing surface of the wireless module.

[0029] 3. This utility model is equipped with a threaded hole, a threaded post, and a mounting plate. When the anti-slip pad needs to be replaced, the operator can rotate the mounting plate. The rotation of the mounting plate drives the threaded post to rotate, causing the threaded post to unscrew out of the threaded hole, thereby removing the anti-slip pad for replacement.

Detailed Implementation

[0039] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0040] The embodiments of this utility model will be described below based on its overall structure.

[0041] Example 1:

[0042] An automated wireless module testing device, such as Figures 1-8 As shown, the device includes a workbench 1 and a lifting plate 16. A monitor 2, a host 3, and a test fixture 4 are placed on the top of the workbench 1. The mouse and keyboard are not shown in the figure, but they need to be placed on the workbench 1 and connected to the host 3 via cables when using the device. Frames 8 are installed on both sides of the top of the lifting plate 16 by bolts 18. Springs 9 are installed inside the frames 8, and movable blocks 10 are connected to the bottom of the springs 9. A pressure rod 21 that penetrates the lifting plate 16 is installed at the bottom of the movable block 10. A threaded hole 13 is opened at the bottom of the pressure rod 21, and a threaded post 14 is threaded inside the threaded hole 13. A mounting plate 22 is installed at the bottom of the threaded post 14, and an anti-slip pad 17 is installed at the bottom of the mounting plate 22. The anti-slip pad 17 prevents the bottom of the pressure rod 21 from directly contacting the wireless module, thus protecting the wireless module. At the same time, the pressure rod 21 can press down on the wireless module, improving the stability of the wireless module.

[0043] Specifically, a test platform 5 is installed on the top of the test fixture 4, and two placement slots 6 are opened on the top of the test platform 5. A support frame 7 is also installed on the top of the test fixture 4. The placement slots 6 are designed to facilitate the placement of wireless modules by the staff, so that the wireless modules can be tested. A threaded rod 11 is provided on the support frame 7. The bottom end of the threaded rod 11 is connected to a lifting plate 16 through a bearing. The movement of the threaded rod 11 will drive the lifting plate 16 to move, and then drive the pressure rod 21 to move, so as to adjust the height of the pressure rod 21. A handle 12 is installed on the top of the threaded rod 11. Support seats are installed on both sides of the bottom of the workbench 1, so that the staff can rotate the threaded rod 11 through the handle 12. The support seats can support the workbench 1.

[0044] See Figures 1-6 The threaded rod 11 is threadedly connected to the support frame 7, allowing the threaded rod 11 to move when rotated. The anti-slip pad 17 and the mounting plate 22 are detachably connected to the threaded hole 13 via the threaded post 14, allowing the anti-slip pad 17 and the mounting plate 22 to be disassembled and replaced. The movable block 10 is slidably connected to the frame 8. The spring 9 is made of stainless steel so that the movable block 10 can slide inside the frame 8, thereby improving the stability of the movable block 10 when it moves. Two first data lines 19 are connected to the test fixture 4. A second data line 20 is connected between the host 3 and the test fixture 4. The display 2 and the host 3 are connected by a cable, facilitating the testing of the non-functional module. The pressure rod 21 is located directly above the placement slot 6 so that when the pressure rod 21 moves down, it can press down the wireless module placed in the placement slot 6.

[0045] Example 2:

[0046] Based on the above embodiment 1, in order to improve the stability of the lifting plate 16 when it moves, it is necessary to guide the lifting plate 16, so the following structure will be set.

[0047] Specifically, a guide rod 15 is installed between the support frame 7 and the test fixture 4. The guide rod 15 passes through the lifting plate 16, and the lifting plate 16 is slidably connected to the guide rod 15. The guide rod 15 can guide the lifting plate 16 and improve the stability of the lifting plate 16 when it moves.

[0048] Example 3:

[0049] Based on the above embodiment one, in order to facilitate the protection of the wireless module, the following materials will be used to make the anti-slip mat.

[0050] See Figures 6-8 The anti-slip pad 17 is made of rubber material to prevent the bottom of the pressure rod 21 from directly contacting the wireless module, thereby protecting the wireless module.

[0051] The working principle of this utility model is as follows: First, in use, connect the keyboard and mouse to the host 3 via cables, then turn on the power and turn on the host 3 and monitor 2. Then, the operator can place the wireless module in the placement slot 6, and then insert the first data cable 19 into the interface of the wireless module. Next, the operator rotates the threaded rod 11 through the handle 12, causing the threaded rod 11 to move down and drive the lifting plate 16 down, and then drive the pressure rod 21 down. The anti-slip pad 17 first contacts the wireless module, and as the lifting plate 16 continues to move down, the anti-slip pad... 17 will deform and the movable block 10 will squeeze the spring 9, causing the spring 9 to be compressed to buffer and prevent the pressure rod 21 from moving too far down and causing damage to the wireless module. At the same time, the pressure rod 21 will be pressed down by the reaction force of the spring 9. Then the second data cable 20 is inserted into the interface of the host 3. Then the burning tool is opened, the parameters are adjusted, and the test program is set so that the wireless module can be tested. After the test, the test results are fed back to the display 2 so that the staff can intuitively view the test results.
