Technical Field

[0001] This invention relates to the field of testing equipment for communication products, and in particular to a simulated SIM card insertion and removal mechanism. Background Technology

[0002] In the fields of communication equipment testing, IoT terminal debugging, and smart card-related equipment R&D, the mechanism for simulating SIM card insertion and removal is a key device to ensure the normal operation and functional verification of the equipment. Currently, most technical solutions for simulating SIM card insertion and removal in the industry use cylinder drive to achieve the insertion and removal work. However, this method lacks precise control and cannot finely adjust the insertion and removal force and speed. Furthermore, when dealing with some precision equipment that requires high insertion and removal accuracy, it is easy to damage the slot due to excessive force or cause poor card contact due to insufficient force, thus affecting the test quality. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a simulated SIM card insertion and removal mechanism to address the above-mentioned technical deficiencies. By connecting the moving detection component and the pushing component with the floating component, the displacement accuracy and the control of the insertion and removal force can be effectively improved, thus ensuring the test quality.

[0005] Preferably, the motion detection component includes a lead screw motor and a photoelectric sensor; the lead screw motor is fixed below the base plate, and the lead screw portion is threadedly connected to the bracket; the photoelectric sensor is arranged on one side of the lead screw motor and connected to the base plate.

[0006] Preferably, a linear guide rail is provided between the seat plate and the bracket.

[0007] Preferably, the linear guides are arranged in pairs.

The floating member is provided with mounting posts symmetrically arranged to cooperate with the countersunk holes, and a spring is sleeved on the mounting posts. A guide post is provided in the middle area of ​​the two mounting posts to cooperate with the guide hole.

[0009] Preferably, a pressure-tension sensor is provided between the floating component and the fixed plate.

[0010] Preferably, the fixing plate is provided with a SIM card slot.

[0011] Preferably, a positioning fixture is provided at the fixed plate, and the positioning fixture is provided with a guide block connected to the fixed plate.

[0012] Preferably, clamping elements are provided at the two opposite corner positions of the positioning fixture.

[0013] Preferably, at least one stop is provided at the corner edge of the positioning fixture near the guide block.

[0014] Compared with the prior art, the present invention has the following advantages: 1. By driving the bracket displacement through a lead screw motor, precise displacement adjustment can be achieved during the testing process. In addition, with the photoelectric sensor for position detection, insertion and removal damage caused by position deviation can be effectively avoided. At the same time, the speed can be infinitely controlled and the force can be controlled, making the simulated SIM insertion process smooth and accurate. 2. The structural design of the pushing and floating components allows the SIM to have a floating amount during the insertion process. Combined with the real-time feedback of the force value by the pressure and pull sensor, the system can prevent damage to the product by setting the insertion and extraction force during the insertion and extraction process through closed-loop protection. 3. This device effectively improves product yield and production capacity during equipment testing by ensuring smooth and precise insertion and removal, and provides closed-loop protection for the product during the insertion and removal process, resulting in higher efficiency.

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments and the accompanying drawings. It should be understood that these descriptions are merely exemplary and not intended to limit the scope of the invention. Furthermore, descriptions of well-known structures and techniques are omitted in the following description to avoid unnecessarily obscuring the concept of the invention.

[0018] Specific implementation method one: Combining Figure 1-8 As shown, a simulated SIM card insertion and removal mechanism includes: a base plate 1, a bracket 2, and a floating component 3; a motion detection component 4 is provided below the base plate 1, the bracket 2 is connected to the motion detection component 4, and the bracket 2 and the base plate 1 are slidably connected. The motion detection component 4 can realize linear drive of the bracket 2 and detect the displacement distance. A pusher 5 connected to the floating component 3 is provided on one side of the bracket 2. A fixing plate 6 for card installation is provided on the floating component 3. The floating component 3 can move within a small range between the pusher 5 and can complete the detection of insertion and removal force.

[0019] Preferred embodiments, in combination Figure 2-3 As shown, the moving detection component 4 includes a lead screw motor 401 and a photoelectric sensor 402. The lead screw motor 401 is fixed below the base plate 1, and the lead screw part is threadedly connected to the bracket 2. A sensing plate is installed at the connection between the bracket 2 and the lead screw. The photoelectric sensor 402 is arranged on one side of the lead screw motor 401 and is fixedly connected to the base plate 1. During the displacement of the bracket 2, the photoelectric sensor 402 can detect the position of the sensing plate in real time and determine the position of the bracket 2, thereby achieving precise displacement control. Moreover, the lead screw structure has higher precision than the traditional pneumatic rod drive, and the speed can be adjusted by adjusting the motor speed, which is convenient for operation and adjustment.

[0020] Preferred embodiments, in combination Figure 2 As shown, a linear guide rail 101 is provided between the base plate 1 and the bracket 2. The connection between the two is realized through the linear guide rail 101, and it can provide linear guiding displacement function. Commercial products can be directly used, which is convenient for design and manufacturing.

[0021] In a preferred embodiment, in order to improve the stability of the displacement of the bracket 2, the linear guide rails 101 are arranged in pairs on both sides to form a stable support and improve the installation accuracy; the linear guide rails 101 can also be arranged individually, and in conjunction with the connection between the bracket 2 and the lead screw, the guiding displacement can also be achieved.

[0022] Preferred embodiments, in combination Figure 4-6 As shown, the pusher 5 is provided with a limiting groove 501, and countersunk holes 502 are symmetrically machined at the front of the limiting groove 501. The countersunk holes 502 are located near the lower edge, and a guide hole 503 is provided in the middle area of ​​the two countersunk holes 502, forming a three-point arrangement with the countersunk holes 502, which makes the support and guidance more stable and reliable. The floating part 3 is symmetrically provided with mounting posts 301 that cooperate with the countersunk holes 502. A spring 302 is sleeved on the mounting post 301. The two ends of the spring 302 are in contact with the countersunk holes 502 and the floating part 3, respectively. A guide post 303 that cooperates with the guide hole 503 is provided in the middle area of ​​the two mounting posts 301. Under normal conditions, the rear of the floating part 3 is in contact with the rear of the limiting groove 501, and the spring force of the spring 302 is used to realize the positioning of the floating part 3. The cooperation between the countersunk holes 502 and the mounting posts 301, as well as the guide holes 503 and the guide posts 303, realizes the support of the floating part 3 and provides guidance and positioning.

[0023] Preferred embodiments, in combination Figure 4 As shown, a pressure-tension sensor 304 is provided between the floating component 3 and the fixed plate 6, which can determine the magnitude of the force during the insertion and removal process.

[0024] Preferred embodiments, in combination Figure 4 As shown, the fixing plate 6 is provided with a SIM card slot 601, which provides a position for installing a SIM card.

[0025] A positioning fixture 7 is provided that can be used in conjunction with the insertion and removal mechanism. Figure 7 and Figure 8 As shown, a positioning fixture 7 is installed at the fixed plate 6. The positioning fixture 7 is provided with a guide block 701 connected to the fixed plate 6. The guide block 701 has a rectangular groove above it. The fixed plate 6 is inserted into the rectangular groove to form a coarse guiding function, which improves the stability of displacement. The positioning fixture 7 provides the installation position of the product.

[0026] Preferred embodiments, in combination Figure 7 As shown, clamping members 8 are provided at the two opposite corners of the positioning fixture 7. By pressing from top to bottom, the product is clamped and positioned.

[0027] Preferred embodiments, in combination Figure 1As shown, near the corner of the guide block 701, at least one stop block 702 is provided at each of the two corner edges of the positioning fixture 7. During product placement, this can assist in positioning the product, thereby improving installation efficiency. Since the left edge of the positioning fixture 7 is relatively long, two more stop block 702 structures can be added to increase the number of positioning points.

[0028] Preferred embodiments, in combination Figure 7 and Figure 8 As shown, the clamping component 8 includes a vertical plate, a cylinder, and a clamping arm; the vertical plate is connected to the frame, the air rod is fixed on the vertical plate, and the end of the push rod is connected to the clamping arm by a pivot. The clamping arm is close to the connection position with the push rod and is also connected to the vertical plate by a pivot. By pushing upward with the air rod, the clamping arm is moved towards the product direction, thereby completing the clamping operation.

[0029] The bracket 2, linear guide 101, pusher 5, etc. are all modularly designed and fixedly connected by screws, which facilitates the overall assembly and allows for replacement in case of partial damage, reducing maintenance costs.

[0030] The contact point between the clamping arm and the product can also be reinforced with a plastic or rubber block. The elasticity of the material itself can prevent damage to the product during clamping, and the elasticity can also prevent excessive clamping force.

[0031] Working principle: The lead screw motor 401 drives the SIM card to float and be inserted into the product. During the insertion process, the guide block 701 provides coarse guidance and positioning, and then the SIM card slot position is precisely guided for insertion. During the insertion process, the pressure and pull sensor 304 provides real-time feedback of the force value. When the force exceeds the set value of insertion and extraction, the lead screw motor 401 will stop driving and an alarm will be triggered, so that the entire insertion and extraction process forms a closed-loop protection for the product.

[0032] It should be understood that the specific embodiments described above are merely illustrative or explanatory of the principles of the invention and do not constitute a limitation thereof. Therefore, any modifications, equivalent substitutions, improvements, etc., made without departing from the spirit and scope of the invention should be included within the protection scope of the invention. Furthermore, the appended claims are intended to cover all variations and modifications falling within the scope and boundaries of the appended claims, or equivalent forms of such scope and boundaries.
