Description

Technical Field

[0001] This utility model relates to the field of smart card manufacturing technology, and in particular to a thrust testing machine for cards. Background Technology

[0002] Smart cards are cards with embedded chips that can interact with readers to exchange data. They are widely used in hotel management, the financial industry, access control systems, and other applications. In some scenarios, such as with phone cards, users need to eject the chip from the card before inserting it into smartphones or other electronic devices. To ensure a good user experience, the force required to eject the chip cannot be too great, otherwise it will be difficult for the user to eject; conversely, the force cannot be too small, otherwise the chip may accidentally detach. Therefore, after production, cards need to undergo a force test to ensure that the force meets expectations.

[0003] In related technologies, the card's pushing force test is performed manually. Specifically, a worker holds a force gauge and slowly pushes the chip, recording the force gauge's count as the chip is pushed out. During the test, the force gauge's movement speed is unstable, leading to inaccurate pushing force test results. Utility Model Content

[0024] Please see Figure 1 and Figure 3 , Figure 1 This is a schematic diagram of the thrust testing machine 100 according to one embodiment of the present invention; Figure 3 yes Figure 1 A schematic diagram of the structure of the fixing plate 30 and the card 200 in the thrust testing machine 100. This utility model embodiment provides a thrust testing machine 100 applied to a card 200. The thrust testing machine 100 includes a base 10 and a testing mechanism 20. The base 10 is used to support the card 200, which includes a frame 220 and a chip 210 embedded in the frame 220. The testing mechanism 20 includes a driver 21 and a thrust tester 22. The driver 21 is mounted on the base 10 and connected to the thrust tester 22. The driver 21 can drive the thrust tester 22 to move towards the chip 210 and push the chip 210 out of the frame 220. The thrust tester 22 is used to obtain the thrust experienced by the chip 210.

[0025] Specifically, the thrust tester 22 is an electronic force gauge, and the base 10 is used to place it on a supporting surface such as the ground. The actuator 21 drives the thrust tester 22 to move in a direction parallel to the vertical direction.

[0026] By setting up the test mechanism 20, the driver 21 in the test mechanism 20 can drive the thrust test gauge 22 to push the chip 210 out of the frame 220 at a slow and stable speed, thereby improving the accuracy of the thrust test results.

[0027] In one embodiment of this implementation, please refer to Figure 1 and Figure 3The thrust testing machine 100 includes a fixing plate 30, which is detachably mounted on the base 10 and used to support and position the card 200. It is understood that, to ensure consistent thrust testing standards, there are certain requirements for the point of application of the thrust test on the card 200. Specifically, the point of application of the thrust is required to be located on the chip 210 and at a certain distance from the frame 220, for example, 0.5 mm. To ensure that the point of application of the thrust test on different cards 200 meets this requirement, a detachable fixing plate 30 is provided on the base 10 to meet the positioning requirements of different cards 200, so that the desired point of application of the thrust on different cards 200 can be aligned with the thrust test gauge 22 during thrust testing.

[0028] Specifically, the fixing plate 30 can be detachably connected to the base 10 by means of clamping with clamping blocks, screw connection, etc.

[0029] In one embodiment of this implementation, please refer to Figure 1 and Figure 3 The fixing plate 30 is provided with a detachable first insert 31 and a second insert 32. The first insert 31 and the second insert 32 are used to abut against two adjacent sides of the card 200, and the fixing plate 30 is used to abut against the other two sides of the card 200. This arrangement allows the card 200 to be fixed in place by the first insert 31 and the second insert 32 in conjunction with the fixing plate 30, preventing displacement of the card 200 during thrust testing and improving testing accuracy. Furthermore, by replacing the first insert 31 and the second insert 32, positioning of cards 200 of different sizes can be achieved, improving the adaptability of the test.

[0030] Specifically, in order to facilitate contact with the card 200, both the first insert 31 and the second insert 32 are provided with pins 33, and the two pins 33 respectively contact the two adjacent sides of the card 200.

[0031] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 , Figure 2 yes Figure 1 A schematic diagram of the thrust testing machine 100 from another perspective. In order to improve the movement accuracy of the thrust tester 22 and ensure the accuracy of the test results, the testing mechanism 20 includes a lifting seat 23, which is slidably engaged with the base 10 and connected to the driver 21. The thrust tester 22 is mounted on the lifting seat 23.

[0032] In one embodiment of this implementation, please refer to Figure 2 and Figure 3The testing mechanism 20 includes a lead screw 24 and a nut 25. The lead screw 24 is connected to the output shaft 211 of the driver 21, and the nut 25 is located on the lifting seat 23 and is threadedly engaged with the lead screw 24. With this configuration, the driver 21 can drive the output shaft 211 to rotate, thereby raising and lowering the thrust tester 22. Simultaneously, the engagement of the lead screw 24 and the nut 25 achieves a certain reduction ratio, ensuring that the thrust tester 22 can slowly and smoothly contact the chip 210 and push the chip 210 out of the frame 220, thus improving the accuracy of the testing structure.

[0033] Specifically, the output shaft 211 of the driver 21 is circumferentially fixedly connected to the lead screw 24 via a coupling 212.

[0034] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 In order to achieve a sliding fit between the lifting seat 23 and the base 10, the lifting seat 23 is provided with a guide sleeve 231, and the base 10 is provided with a guide rod 11 that cooperates with the guide sleeve 231.

[0035] Specifically, in order to further improve the movement accuracy of the thrust tester 22, there are multiple guide sleeves 231 and guide rods 11, which are matched one-to-one.

[0036] In this embodiment, there are two guide sleeves 231 and two guide rods 11.

[0037] In one embodiment of this implementation, please refer to Figure 2 and Figure 3 One of the lifting seat 23 and the base 10 is provided with a first sensor 232, and the other is provided with a first sensing block 12. The first sensor 232 is electrically connected to the driver 21. When the lifting seat 23 slides relative to the base 10 to a first preset position (i.e., when...), Figure 1 and Figure 2 As shown in the figure, the first sensing block 12 is within the sensing range of the first sensor 232. The first sensor 232 controls the driver 21 to stop driving. When the lifting seat 23 is in the first preset position, the chip 210 is detached from the frame 220. This setting allows the thrust tester 22 to stop moving in time (i.e., to the lower limit position) after the chip 210 is pushed out, avoiding interference.

[0038] Specifically, in this embodiment, the first sensor 232 is disposed on the lifting base 23, and the first sensing block 12 is disposed on the base 10. In other embodiments, the first sensor 232 may also be disposed on the base 10, and the first sensing block 12 may also be disposed on the lifting base 23.

[0039] In one embodiment of this implementation, please refer to Figure 1 and Figure 2In order to facilitate the adjustment of the lower limit position of the thrust tester 22, the first sensing block 12 is slidably fitted onto the base 10.

[0040] Specifically, the first sensing block 12 is provided with a first screw 121, one end of which abuts against the base 10. The user can fix the relative position of the first sensing block 12 and the base 10 by tightening the first screw 121, and the user can also loosen the first screw 121 to allow the first sensing block 12 to slide relative to the base 10.

[0041] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 One of the lifting seat 23 and the base 10 is equipped with a second sensor 233, and the other is equipped with a second sensing block 13. The second sensor 233 is electrically connected to the driver 21. When the lifting seat 23 slides relative to the base 10 to a second preset position, the second sensing block 13 is within the sensing range of the second sensor 233, and the second sensor 233 controls the driver 21 to stop driving. When the lifting seat 23 is in the second preset position, the thrust tester 22 has a preset distance from the chip 210. This setting can prevent the thrust tester 22 from moving excessively away from the card 200, and the thrust tester 22 can stop in time at the upper limit position to avoid interference.

[0042] Specifically, in this embodiment, the second sensor 233 is disposed on the lifting base 23, and the second sensing block 13 is disposed on the base 10. In other embodiments, the second sensor 233 may also be disposed on the base 10, and the second sensing block 13 may also be disposed on the lifting base 23.

[0043] In one embodiment of this implementation, please refer to Figure 1 and Figure 2 In order to facilitate the adjustment of the upper limit position of the thrust tester 22, the second sensing block 13 is slidably fitted onto the base 10.

[0044] Specifically, the second sensing block 13 is provided with a second screw 131, one end of which abuts against the base 10. The user can fix the relative position of the second sensing block 13 and the base 10 by tightening the second screw 131, and the user can also loosen the second screw 131 to allow the second sensing block 13 to slide relative to the base 10.

[0045] Specifically, the first sensor 232 and the second sensor 233 can be selected as sensors of the type of photoelectric sensor, infrared sensor, etc.

[0046] Specifically, the base 10 is provided with a measuring scale 14, the scale direction of the measuring scale 14 is parallel to the sliding direction of the lifting seat 23, and the first sensing block 12 and the second sensing block 13 are provided on the adjacent side of the measuring scale 14.

[0047] Specifically, the base 10 is equipped with an origin switch 15, which is electrically connected to the driver 21 and is used to sense the position of the lifting seat 23. When the thrust test is completed, the driver 21 drives the thrust test gauge 22 away from the card 200 and reaches the origin position. At this point, the origin switch 15 senses the lifting seat 23 and controls the driver 21 to stop driving. In this embodiment, the origin position is located between the first preset position and the second preset position.

[0048] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
