Technical Field
[0001] This utility model relates to the field of 5G testing technology, specifically a 5G test SIM card testing device. Background Technology
[0002] As the fifth generation of mobile communication network, 5G network has a peak theoretical transmission speed of tens of gigabytes per second, which is hundreds of times faster than the transmission speed of 4G network. The main goal of 5G network is to keep end users connected to the network at all times. When the network is transmitting data, it needs to use corresponding signal testing equipment. Usually, the testing equipment only has one SIM card slot, which can only hold one SIM card. Therefore, when conducting polling tests with multiple SIM cards, it is necessary to manually insert and remove SIM cards to perform card replacement tests.
[0003] Most of the small card testing equipment currently in use requires operators to manually insert the module into a fixed socket or connect it with a cable. This requires plugging and unplugging for each test, which is inefficient and the interfaces are prone to wear. Furthermore, the equipment lacks an automatic pressing mechanism driven by a cylinder, and the connection consistency depends entirely on the operator's manual operation. This can easily lead to poor contact due to uneven force, affecting the reliability of the test results. Utility Model Content
[0004] The purpose of this invention is to provide a 5G test card testing device to solve the problems raised in the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a 5G test SIM card testing device, comprising an operating platform, a test box, a filter, a universal pin module, and a carrier. The test box is positioned directly above the operating platform, and a cover plate is positioned directly above the test box. Locking buckles are rectangularly distributed on the outer side of the cover plate. An opening and closing mechanism is provided on the outer side of the test box. This mechanism uses a cylinder to move the test box at the top of the operating platform, and simultaneously uses an electric cylinder to vertically raise the cover plate, thereby opening the cover plate and test box. A filter is positioned on one side of the operating platform. A detection mechanism is located inside the test box. The detection mechanism uses an RF cable management block to fix the SIM card antenna area, and simultaneously uses the universal pin module to collect the SIM card's current and voltage to verify whether it meets specifications.

[0007] As a preferred technical solution, the electric cylinder is connected to the top of the guide rail via a slider seat at the bottom, and the guide rail and the cylinder are alternately distributed at the top of the operating platform.
[0008] As a preferred technical solution, the electric cylinder is connected to one side of the test box via a cable chain connected to its tail end.
[0009] As a preferred technical solution, the testing mechanism includes a pressing module, a floating pressure block, a tray, a universal needle module, guide posts, a second cylinder, a carrier, a spring, and an RF cable management block. The floating pressure block is located directly below the pressing module, and the tray is located below the floating pressure block.

[0011] As a preferred technical solution, the guide posts on both sides of the bottom of the floating pressure block are connected through the interior of the operating platform.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses a 5G SIM card testing device with an operating platform to provide basic support. The guide column, tray, and carrier enable precise positioning of the SIM card. The electric cylinder, pneumatic cylinder, and spring drive the pressing and feeding / unloading actions.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] Example: Figure 1 and Figure 2 As shown, this utility model provides the following technical solution: a 5G test SIM card testing device, including an operating platform 1, a test box 3, a filter 10, a universal pin module 16, and a carrier 19. The test box 3 is arranged directly above the operating platform 1, and a cover plate 4 is arranged directly above the test box 3. Locking buckles 6 are rectangularly distributed on the outer side of the cover plate 4. An opening and closing mechanism 7 is arranged on the outer side of the test box 3. The opening and closing mechanism 7 uses a cylinder 8 to move the test box 3 at the top of the operating platform 1, and simultaneously uses an electric cylinder 5 to vertically raise the cover plate 4, so that the cover plate 4 and the test box 3 are opened. A filter 10 is arranged on one side of the operating platform 1. A detection mechanism 15 is arranged inside the test box 3. The detection mechanism 15 fixes the SIM card antenna area through an RF cable clamping block 21, and simultaneously uses the universal pin module 16 to collect the current and voltage of the SIM card to verify whether it meets the specifications.
[0018] Among them, filter 10 is installed on the side of the operating platform 1 and connected to the AC220V power input terminal. It filters out the high-frequency electromagnetic interference generated during the 5G small card test through the LC filter circuit and smooths the power grid voltage fluctuations, providing a stable power supply environment for the electric cylinder 5 and the pneumatic cylinder 8 of the test equipment.
[0019] like Figure 1 , Figure 2 and Figure 3 As shown, the opening and closing mechanism 7 includes a cylinder 8, a cable chain 9, a guide rail 2, a test chamber 3, a cover plate 4, an electric cylinder 5, and a slider seat 14. The cylinder 8 is installed at the top of the operating platform 1. The test chamber 3 is located directly above the operating platform 1. Electric cylinders 5 are installed on both sides of the test chamber 3. The slider seat 14 is located at the bottom of the electric cylinder 5. The guide rail 2 is located at the top of the operating platform 1. The cover plate 4 is located at the top of the test chamber 3. The output end of the cylinder 8 is connected to one side of the test chamber 3. The electric cylinder 5 is connected to the top of the guide rail 2 through the slider seat 14 at its bottom. The guide rail 2 and the cylinder 8 are staggered at the top of the operating platform 1. The electric cylinder 5 is connected to one side of the test chamber 3 through the cable chain 9 connected to its tail end.
[0020] The guide rail 2 is installed at the top of the operating platform 1. The slider seat 14 is embedded in the guide rail 2 and fixedly connected to the bottom of the electric cylinder 5. The guide rail 2 guides the electric cylinder 5 to ensure horizontal movement without deviation, preventing the cover plate 4 from jamming due to tilting of the electric cylinder 5. The microcontroller controls the electric cylinder 5 to start vertically. The output shaft of the electric cylinder 5 pushes the cover plate 4 vertically upwards along the Z-axis until the cover plate 4 is completely detached from the top of the test chamber 3.
[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the testing mechanism 15 includes a pressing module 11, a floating pressure block 12, a support plate 13, a universal needle module 16, a guide post 17, a cylinder 18, a carrier 19, a spring 20, and an RF cable management block 21. The floating pressure block 12 is positioned directly below the pressing module 11, and the support plate 13 is positioned below the floating pressure block 12. The universal needle module 16 is positioned above one side of the support plate 13, and the carrier 19 is positioned directly below the universal needle module 16. The other side of the floating pressure block 12 is... There is a second cylinder 18, which is installed inside the test chamber 3. An RF cable management block 21 is installed above the floating block 12. The bottom end of the spring 20 is connected to the top end of the support plate 13. The guide posts 17 are installed on both sides of the bottom end of the floating block 12. The support plate 13 is connected to the bottom end of the carrier 19 through the springs 20 symmetrically arranged at the top end. The carrier 19 is parallel to the universal needle module 16. The guide posts 17 installed on both sides of the bottom end of the floating block 12 are connected through the interior of the operating platform 1.
[0022] Among them, the guide post 17 provides high-precision guidance for the vertical movement of the pressing module 11 to avoid deviation during the pressing process; the spring 20 absorbs the impact energy in the early stage of pressing through elastic deformation and assists the pressing module 11 to reset after the test is completed.
[0023] The working principle of this utility model is as follows: The control cylinder 8 is installed at the top of the operating platform 1 and starts. The output end of the cylinder 8 pushes the test box 3 to move horizontally away from the test area of the operating platform 1. Through the cooperation of the guide rail 2 and the slider seat 14, the slider seat 14 at the bottom of the electric cylinder 5 is embedded in the guide rail 2 to ensure that the horizontal movement of the test box 3 is without deviation. After the test box 3 is completely moved out, the microcontroller controls the electric cylinder 5 to be installed on both sides of the test box 3. The bottom end is connected to the guide rail 2 through the slider seat 14 and starts. The output shaft of the electric cylinder 5 pushes the cover plate 4 to rise vertically. The tail end of the electric cylinder 5 is connected to the side of the test box 3 via a cable chain 9. The power cable of the electric cylinder 5, the sensor circuit of the cover plate 4, and the signal line of the detection mechanism 15 are run through the inside of the cable chain 9 to prevent the circuit from being pulled and broken due to movement. After the test box 3 and the cover plate 4 are fully opened, the operator or robotic arm puts the 5G card to be tested into the carrier 19. The surface of the carrier 19 has a positioning reference groove that matches the notch angle of the card. The carrier 19 is mounted on the top of the tray 13. The tray 13 is connected to the guide rail 2 via the slider seat 14 at the bottom. Its surface has a positioning reference groove that matches the notch angle of the M.2 small card. The guide post 17 penetrates the interior of the operating platform 1. Its top end is fixedly connected to the bottom end of the pressing module 11, and its bottom end is fixed to the base of the operating platform 1 by a bearing. The microcontroller controls the electric cylinder 5 to retract, and the output shaft pulls the cover plate 4 vertically downward along the Z-axis until the rectangular distribution of the latches 6 on the cover plate 4 is aligned with the locking holes of the test box 3. After the latches 6 are locked, the test box 3 and the cover plate 4 form a closed test space. The floating pressure block 12 is installed at the bottom of the pressing module 11. Through the first-level double floating structure, it adapts to the edge height deviation of the small card and the thickness difference of different M.2 cards, ensuring uniform force during pressing. The cylinder 18 is horizontally driven and installed inside the test box 3. Its output end is connected to the side of the pressing module 11. It is driven by air pressure to push the pressing module 11 to descend vertically along the guide post 17 until the floating pressure block 12 completely presses the small card. The universal pin module 16 inside the test box 3 includes two sets of pin modules, Socket-A and Socket-B. When the card is pressed into place, the pins contact the gold fingers of the card one by one, realizing the electrical connection between the card and the test equipment. The RF cable management block 21 is installed on the other side of the floating block 12, corresponding to the RF antenna area of the card. It fixes the RF antenna of the card by elastic pressing, avoiding signal attenuation or interruption caused by antenna displacement during the test, and ensuring stable transmission of high-frequency signals (such as millimeter waves).
[0024] The general-purpose pin module 16 collects parameters such as standby current, transmit current, and operating voltage of the small card through pins and transmits them to the microcontroller to verify whether they meet the design specifications. The test equipment sends CMD commands to the small card through the general-purpose pin module 16 and transmits 5G test signals through the RF cable management block 21 to verify the throughput, latency, connection stability and other performance indicators of the small card.

Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description.
