[0026] See Figures 1 to 10 As shown, this embodiment of the invention provides a smart card testing insertion and removal device, including: a frame 1, a test station 2, a drive mechanism 3, and a connector 4; the test station 2 and the drive mechanism 3 are both mounted on the frame 1; the connector 4 is mounted on the end of the drive mechanism 3 near the test station 2; the test station 2 is used to access a smart card; the connector 4 is pluggably connected to the smart card on the test station 2; the drive mechanism 3 is used to drive the connector 4 to move back and forth along the insertion and removal direction.

[0027] Specifically, in this embodiment, the drive mechanism 3 drives the connector 4 to perform automatic insertion and removal operations, replacing the traditional manual insertion and removal method. This effectively improves the insertion and removal efficiency of smart card testing, while ensuring that the force and angle of each insertion and removal are consistent. This avoids damage to the smart card or test connector 42 caused by improper manual operation, and improves the stability of insertion and removal contact and the accuracy of test results.

[0028] See Figures 1 to 4 As shown, in one embodiment, the drive mechanism 3 includes a first guide component 31, a drive component 32, and a connecting seat 33. The first guide component 31 is connected to the frame 1, the drive component 32 is movably connected to the first guide component 31, and one end of the drive component 32 near the connector 4 is connected to the connecting seat 33. The connector 4 is mounted on the connecting seat 33.

[0029] Specifically, in this embodiment, the first guide component 31 provides guidance for the drive component 32, ensuring that the drive component 32 can move smoothly along the preset insertion and removal direction. At the same time, the power of the drive component 32 is transmitted to the connector 4 through the connector 33, making the movement of the connector 4 more stable and reliable, and further improving the accuracy and consistency of the insertion and removal operation.

[0030] In one embodiment, the drive assembly 32 is a quick clamp assembly and has a sliding shaft 321 that is slidably connected to the first guide assembly 31.

[0031] Specifically, this embodiment uses a quick-clamp assembly as the driving assembly 32, which features simple operation and rapid response, enabling the connector 4 to be inserted and removed quickly, further improving testing efficiency. Simultaneously, the sliding connection structure between the sliding shaft 321 and the first guide assembly 31 ensures that the sliding shaft 321 of the quick-clamp assembly can move smoothly in a straight line, preventing the connector 4 from shifting during insertion and removal, thus ensuring the accuracy of insertion and removal.

[0032] In one embodiment, the drive mechanism 3 further includes a second guide component 34, which is connected to the frame 1, and the connecting seat 33 is movably connected to the second guide component 34.

[0033] Specifically, this embodiment adds a second guide component 34 to provide additional guide support for the connector 33, making the connector 33 more stable during movement, effectively reducing the shaking and offset of the connector 33, thereby ensuring that the connector 4 installed on the connector 33 can accurately connect with the smart card on the test station 2, further improving the reliability and stability of the insertion and removal operation.

[0034] See Figure 5 As shown, in one embodiment, the connecting seat 33 is provided with a slider 331, the second guide component 34 includes an optical axis 341 and connecting blocks 342 respectively connected to both ends of the optical axis 341, the connecting blocks 342 are also connected to the frame 1, and the slider 331 is slidably connected to the optical axis 341.

[0035] Specifically, this embodiment uses the cooperative structure of optical axis 341 and slider 331 as the second guide component 34, which has the advantages of simple structure, high guiding accuracy and low frictional resistance. It enables the connector 33 to move smoothly along optical axis 341, further improving the stability of connector 4 movement and the accuracy of insertion and removal. At the same time, the structure of optical axis 341 and slider 331 is easy to install and maintain, reducing the production cost and maintenance cost of the device.

[0036] In one embodiment, the connector 33 is connected to a cable bundle 35 on the side near the frame 1. After passing through the frame 1, the cable 5 is constrained by the cable bundle 35 and the connector 33 and connected to the connector 4.

[0037] Specifically, in this embodiment, by setting a cable bundle 35 on the side of the connector 33 near the frame 1, the cable 5 connected to the connector 4 can be neatly arranged and fixed, preventing the cable 5 from getting tangled, pulled or displaced as the connector 33 moves during insertion and removal. This avoids damage to the cable 5 due to excessive bending or pulling, and also makes the wiring inside the device neater and more orderly, facilitating subsequent maintenance and repair, and improving the overall reliability and service life of the device.

[0038] See Figures 3 to 5 As shown, in one embodiment, the connector 33 is connected to a first positioning component 36, and the frame 1 is connected to a second positioning component 37; when the connector 4 moves to the insertion position, the second positioning component 37 is detachably connected to the first positioning component 36.

[0039] Specifically, this embodiment, by setting the first positioning component 36 and the second positioning component 37, can position and fix the connector 33 when the connector 4 moves to the insertion position, preventing the connector 4 from being displaced due to accidental vibration or external force during the test, ensuring stable contact between the connector 4 and the smart card, and thus ensuring the smooth progress of the test process and the accuracy of the test results.

[0040] See Figures 7 to 8 As shown, in one embodiment, the second positioning component 37 includes a connecting frame 371, an adjustable connector 372, and a pin 373. The pin 373 is connected to the connecting frame 371 through the adjustable connector 372. The first positioning component 36 is provided with a positioning hole 3641. The pin 373 is inserted into the positioning hole 3641.

[0041] Specifically, this embodiment employs a positioning method where the pin 373 engages with the positioning hole 3641. This method is simple, reliable, and easy to operate. Furthermore, the position of the pin 373 can be adjusted via the adjustable connector 372, ensuring precise insertion into the positioning hole 3641. This guarantees the accuracy and reliability of the positioning and adapts to positioning requirements under varying installation error conditions.

[0042] In one embodiment, the adjustable connector 372 includes a shaft sleeve 3721, a fixing bolt 3722, and a spring 3723; the spring 3723 is installed inside the shaft sleeve 3721 and is concentrically arranged with the shaft sleeve 3721; the shaft sleeve 3721 passes through the connecting bracket 371 and is threadedly connected to the fixing bolt 3722; the pin 373 extends into the shaft sleeve 3721 and is kinetically connected to the spring 3723; in the default state, the pin 373 extends out of the shaft sleeve 3721 to insert into the positioning hole 3641; by manipulating the pin 373, the pin 373 retracts to disengage from the positioning hole 3641.

[0043] Specifically, this embodiment achieves the automatic reset function of the pin 373 through the transmission connection between the spring 3723 and the pin 373. The pin 373 can be kept in the extended state without additional operation, simplifying the positioning operation steps. At the same time, the threaded connection structure between the shaft cylinder 3721 and the fixing bolt 3722 facilitates the adjustment of the installation position and extension length of the pin 373, further improving the flexibility and reliability of positioning.

[0044] See Figure 6 As shown, in one embodiment, the first positioning component 36 includes a first connecting plate 361, an isolation plate 362, a second connecting plate 363, and a positioning plate 364 connected in sequence. The first connecting plate 361 is installed on the end face of the connecting seat 33 away from the test station 2. The isolation plate 362 extends from the first connecting plate 361 to the end away from the test station 2, and the second connecting plate 363 extends from the isolation plate 362 to the side away from the connecting seat 33. The first connecting plate 361, the isolation plate 362, and the second connecting plate 363 are connected in a stepped shape, and the isolation plate 362, the second connecting plate 363, and the positioning plate 364 are connected in a Π shape. The positioning plate 364 is located on the side of the second connecting plate 363 away from the connecting seat 33, and the positioning hole 3641 is provided on the positioning plate 364.

[0045] Specifically, the first positioning component 36 in this embodiment adopts a structure combining a stepped shape and a Π shape, which effectively improves the overall structural strength and bending resistance of the first positioning component 36, enabling it to withstand greater positioning forces without easily deforming. Simultaneously, this structure keeps the positioning plate 364 away from the movement area of ​​the connecting seat 33, preventing interference between the positioning component and other structures, and also provides sufficient space for the insertion operation of the pin 373, improving the convenience and reliability of the positioning operation.

[0046] See Figure 4 , Figure 9 and Figure 10As shown, in one embodiment, the connector 4 is connected to the connector 33 by a floating screw 38, the length direction of which is the same as the insertion / removal direction of the connector 4.

[0047] Specifically, in this embodiment, the connector 4 and the connector 33 are connected in a floating manner by a floating screw 38, so that the connector 4 has a certain floating margin during the insertion process. This can automatically compensate for the positional deviation between the smart card and the connector 4, avoid insertion difficulties or damage to the connector 42 caused by positional deviation, and further improve the success rate of insertion and removal operations and the fault tolerance of the device.

[0048] See Figure 9 As shown, in one embodiment, the connector 4 includes a fixing component 41 and a connector 42. The two opposite ends of the fixing component 41 are respectively connected to the floating screw 38 and the connector 42. The cable 5 passes through the fixing component 41 and is connected to the connector 42.

[0049] Specifically, in this embodiment, the cable 5 and the connector 42 are fixedly connected by the fixing component 41, which can effectively protect the connection part between the cable 5 and the connector 42 and prevent the cable 5 from being damaged by pulling during insertion and removal. At the same time, the fixing component 41 also provides stable support for the connector 42, ensuring that the connector 42 can be accurately inserted into the smart card, thereby improving the overall structural strength and service life of the connector 4.

[0050] See Figure 10 As shown, in one embodiment, the fixing component 41 includes a support block 411, a buffer layer 412, and a fastener 413; the two opposite end faces of the support block 411 are respectively connected to the floating screw 38 and the buffer layer 412; the support block 411 also has an isolation portion 4111 extending toward the fastener 413; the isolation portion 4111 passes through the buffer layer 412 and is connected to the fastener 413; one end of the fastener 413 away from the isolation portion 4111 is connected to the connector 42; two bundles of cables 5 pass through the support block 411 and the buffer layer 412 and are connected to the connector 42, and the two bundles of cables 5 are respectively located on opposite sides of the isolation portion 4111.

[0051] Specifically, in this embodiment, the buffer layer 412 can absorb the impact force generated during the insertion process, protecting the connector 42 and the smart card from damage. At the same time, the isolation part 4111 separates the two bundles of cables 5, avoiding mutual interference between the cables 5 and ensuring the stability and accuracy of signal transmission.

[0052] See Figure 2 As shown, in one embodiment, the test station 2 has a shielded chamber 21 for inserting a smart card, and the connector 4 is provided with a clearance hole 22 communicating with the shielded chamber 21.

[0053] Specifically, in this embodiment, by setting a shielded chamber 21 at the test station 2, interference from external electromagnetic signals to the smart card testing process can be effectively shielded, ensuring the purity of the test signal and the accuracy of the test results. At the same time, the clearance hole 22 provides a channel for the connector 4 to be inserted, allowing the connector 4 to smoothly enter the shielded chamber 21 and connect to the smart card.

[0054] See Figures 1 to 10 As shown, in addition, this embodiment of the invention also provides a testing system, including a test fixture 6 and at least one insertion / removal device for smart card testing as described above. The test fixture 6 is connected to the rack 1, electrically connected to the test station 2, and connected to the connector 4 via a cable 5.

[0055] Specifically, the test fixture 6 integrates a motherboard, control board, fan and other structures. The test system of this embodiment adopts the above-mentioned insertion and removal device for smart card testing, which can realize automatic insertion and removal testing of smart cards, effectively improving test efficiency and accuracy of test results. At the same time, multiple insertion and removal devices can be set according to test requirements to realize multi-station simultaneous testing, further improving the production testing efficiency of smart cards.

[0056] The above embodiments are preferred implementations of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious substitutions without departing from the concept of the present technical solution are within the protection scope of the present invention.
