[0002] An IC card, or integrated circuit card, is a card in which a microelectronic chip is embedded in a card base. Before leaving the factory, IC cards must undergo a mechanical strength test. A special instrument is used to perform 50 crush tests on each side of the chip, and then the chip's reset behavior is observed to see if there are any abnormalities.
[0003] Existing mechanical strength testing devices mostly use a single set of rollers, primarily for testing single-core cards. When testing multi-core cards, the position of the metal rollers is difficult to determine, making it impossible to ensure the rollers are centered and parallel to the chip, leading to inaccurate test results. Furthermore, for multi-core cards, completing single / double-sided testing requires numerous passes, making the operation cumbersome. Therefore, there is an urgent need for a mechanical strength testing device for multi-core cards to solve these problems. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

Additionally, features defined with "first" and "second" may explicitly or implicitly include one or more of that feature.
[0029] As per the instruction manual Figure 1 As shown, this utility model provides a multi-core card mechanical strength testing device, including a testing component 3, a positioning plate 4, and a clamping component 5 for holding the card 1 to be tested. The testing component 3 includes a set of testing rollers. The positioning plate 4 has multiple mounting positions. The clamping component 5 is selectively connected to one of the mounting positions so that a portion of the chip is located on the testing path. The positioning plate 4 is connected to a driving component 6 for driving it closer to or further away from the set of testing rollers. In this embodiment, the testing path is parallel to the movement path of the positioning plate 4. The testing path refers to the path along which the chip can be inserted into / removed from the set of testing rollers during the movement of the positioning plate 4. By adjusting the mounting position of the clamping component 5, at least a portion of the chip is located on the testing path each time for mechanical strength testing.
[0030] Specifically, the testing device can be used for testing multi-chip cards, which are cards integrating multiple chips. Mechanical strength testing requires testing both the front and back of the card. For multi-chip cards with misaligned chips, the clamping positions need to be adjusted multiple times to meet the testing requirements of each chip. The positioning plate 4 has multiple mounting positions, eliminating the need to replace the clamping component 5. Adjusting the position of the clamping component 5 on the positioning plate 4 allows for the adjustment of the chip positions to meet testing requirements. In this application, "multiple" refers to two or more chips.
[0031] Preferably, the testing device further includes a housing 2, and the testing component 3 and the driving component 6 are both disposed on the housing 2.
[0032] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 2As shown, the positioning plate 4 has two mounting positions, which are arranged longitudinally side by side. These two mounting positions are designated as the first mounting position 41 and the second mounting position 42. The first mounting position 41 is used for testing the front of the card under test 1, and the second mounting position 42 is used for testing the back of the card under test 1. Specifically, the card under test 1 is clamped onto the clamping assembly 5 with its front side facing up, and then the clamping assembly 5 is fixed to the first mounting position 41. At this time, part of the chip is located on the test path and can be used for testing. Similarly, the card under test 1 is clamped onto the clamping assembly 5 with its back side facing up, and then the clamping assembly 5 is fixed to the second mounting position 42. At this time, part of the chip is located on the test path and can be used for testing.
[0033] Preferably, the positioning plate 4 has a limiting groove 43, and the first mounting position 41 and the second mounting position 42 are located in the limiting groove 43. To facilitate the installation of the clamping assembly 5 on the positioning plate 4, positioning posts are provided on both the first mounting position 41 and the second mounting position 42.
[0034] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 3 As shown, the clamping assembly 5 includes a clamping body 51, on which a mounting part 52 is provided. The mounting part 52 is connected to the mounting position of the positioning plate 4. The clamping body 51 has a card slot 53, and the card slot 53 is provided with several fasteners 54 for fixing the card to be tested 1. The fasteners 54 are preferably threaded knobs, which are threadedly connected to the clamping body 51. The edge of the card to be tested 1 is inserted into the card slot 53, and the threaded knob is tightened. The front end of the threaded knob abuts against the card to be tested 1, thereby fixing the card to be tested 1 onto the clamping body 51. The clamping body 51 is placed into the limiting groove 43 of the positioning plate 4, and the mounting part 52 is aligned with one of the mounting positions and fixed, completing the installation of the card to be tested 1 on the positioning plate 4.
[0035] In an optimized implementation, the clamping body 51 is a U-shaped clamping body, with the open end of the U-shaped clamping body facing the test roller assembly. The card to be tested 1 is fixed on the positioning plate 4, and then, under the action of the driving component 6, moves closer to or further away from the test roller assembly, completing the insertion and removal of the card to be tested 1 from the test roller assembly.
[0036] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 4 As shown, the test roller group includes at least one set of lower roller groups 31 and at least one set of upper roller groups 32. The upper roller groups 32 and lower roller groups 31 are arranged in a one-to-one correspondence, and the distance between each upper roller group 32 and its corresponding lower roller group 31 is adjustable. In this embodiment, each lower roller group 31 includes two lower rollers, and each upper roller group 32 includes one upper roller. The upper roller is positioned between the two lower rollers and is higher than the lower rollers. The vertical distance between the upper rollers and the lower rollers is adjustable to meet different testing requirements.
[0037] Specifically, the test component 3 also includes a test base 33, which is disposed on the housing 1. The test base 33 has a groove for mounting a lower roller, and the lower roller is movably connected to the test base 33 via a rotating shaft.
[0038] Preferably, the testing assembly further includes a load-bearing component 34, weights 35, and a lifting mechanism. The load-bearing component 34 is disposed on the lifting mechanism, the weights 35 are disposed on the load-bearing component 34, and the upper roller assembly 32 is disposed at the bottom of the load-bearing component 34. The lifting mechanism is mounted on the testing base 33, and the upper roller assembly 32 is disposed on the load-bearing component 34 via a rotating shaft. The load-bearing component 34 can move up and down along the lifting mechanism. Weights 35 are disposed above the load-bearing component 34, and the testing parameters can be adjusted by setting different weights 35 to meet different testing requirements of the chip.
[0039] In this embodiment, the lifting mechanism includes a second slide rail 36 and a second sliding sleeve. The second slide rail is vertically arranged and mounted on the test base 33. The second sliding sleeve is mounted on the second slide rail 36 and can move up and down along the second slide rail 36. The load-bearing component 34 is mounted on the second sliding sleeve 36. During testing, the drive component 6 moves the card under test 1 toward the test roller group. Part of the chip is aligned with the test roller group. The card under test 1 is inserted into the test roller group. The card under test 1 pushes the upper roller to move upward along the second slide rail 36. The upper roller and the lower roller roll the chip. The drive component 6 moves the card under test 1 away from the test roller group, completing one mechanical strength test. The load-bearing component 34 moves downward along the second slide rail 36 under its own weight and the weight of the weight 35. The above insertion and removal operation is repeated until the set number of tests is completed.
[0040] In this embodiment, two sets of lower roller groups 31 and two sets of upper roller groups 32 are provided. The two sets of lower roller groups 31 are respectively arranged on the test base 33 and distributed longitudinally at intervals. The distance between them is determined according to the distance between the chips on the card to be tested. There are two load-bearing components 34, weights 35, and lifting mechanisms, which are used to adjust the two sets of upper roller groups respectively. The two weights 35 can be set as needed, and can be the same or different to meet different testing requirements. Of course, in some embodiments, the two sets of upper roller groups 32 can be set on one load-bearing component 34, and the two sets of upper roller groups 32 can be adjusted synchronously.
[0041] Of course, in some embodiments, three sets of lower roller groups 31 and three sets of upper roller groups 32 can be provided, and the number and position of the roller groups can be set as needed.
[0042] In an optimized implementation, the housing 2 is provided with a positioning groove 21. The length direction of the positioning groove 21 is parallel to the test path. The length of the positioning groove 21 is greater than the width of the test base 33. The test base 33 is installed on the positioning groove 21. The installation position of the test base 33 on the positioning groove 21 can be adjusted as needed, thereby coarsely adjusting the distance between the test roller group and the initial position of the positioning plate 4.
[0043] Optimized implementation methods, as shown in the appendix to the instruction manual. Figure 5 As shown, the driving assembly 6 includes a first slide rail 61, a first sliding sleeve, and a driving unit. The length direction of the first slide rail 61 is parallel to the test path. The first sliding sleeve is disposed on the first slide rail 61 and can move along the first slide rail 61. The positioning plate 4 is disposed on the first sliding sleeve and is connected to the output end of the driving unit. The first slide rail 61 is disposed on the housing 2, and the positioning plate 4 can move along the first slide rail 61 under the action of the driving unit, thereby realizing the insertion and removal of the card under test 1 on the test roller assembly.
[0044] In an optimized implementation, the drive unit includes a motor 62, a rotating wheel 63, a first connecting plate 64, and a second connecting plate 65. The rotating wheel 63 is connected to the output end of the motor 62 and rotates under the drive of the motor 62. The first end of the first connecting plate 64 is connected to the edge of the rotating wheel 63 through a linkage shaft 66, and the second end is movably connected to the second connecting plate 65 through the linkage shaft 66. The positioning plate 4 is disposed on the second connecting plate 65. That is, when the rotating wheel 63 rotates, the positioning plate can reciprocate left and right through the first connecting plate 64 and the second connecting plate 65.
[0045] The optimized implementation also includes a control panel 7, which includes a start button, a power button, and a test count controller. The motor is electrically connected to the control panel and can control the reciprocating motion of the card under test by setting the number of test counts.
[0046] This embodiment uses a four-core card as the test card 1 for detailed explanation, as shown in the attached instruction manual. Figure 6The diagram shows the structure of the card under test 1. The card under test 1 has four chips, labeled chip A, chip B, chip C, and chip D. Chips A and B are arranged longitudinally, as are chips C and D. The spacing between chips A and B is equal to the spacing between chips C and D. When the card under test is rotated horizontally by 180°, chip A falls to the original position of chip D, chip B falls to the original position of chip C, chip C falls to the original position of chip B, and chip D falls to the original position of chip A. The distance from chip A to the adjacent long side of the card is different from the distance from chip B to the adjacent long side of the card. Therefore, when the card under test 1 is flipped for back-side testing, the chips will deviate from the original test path. The clamping position of the card under test 1 needs to be adjusted to ensure the chip test path is consistent. The chips can be inserted / removed from the test roller assembly for mechanical strength testing.
[0047] The testing steps for the front of card 1 are as follows:
[0048] S1: Insert the card to be tested 1 into the card slot 53 and fix it with the fastener 54;
[0049] S2: The clamping assembly 5 containing the card to be tested 1 is installed on the first mounting position 41 of the positioning plate 4. At this time, the chip C and the chip D are close to the test roller group, and the distance between the two lower roller groups 31 is equal to the distance between the chip C and the chip D.
[0050] S3: Select the specified weight 35, set the number of tests, turn on the power switch and press the start button to test. The drive unit drives the card under test 1 to move back and forth left and right to test chip C and chip D.
[0051] S4: After completing the tests of chip C and chip D, remove the card to be tested 1 and rotate it horizontally by 180° so that chip A and chip B are close to the test roller group. Fix the chip to be tested 1 on the clamping assembly 5 and repeat operation S3 to test chip A and chip B.
[0052] After completing the front test of the chip under test, flip the chip under test so that the back side is facing up, install the clamping component 5 on the second mounting position 42 of the positioning plate 4, and repeat the above operation to complete the back test of the chip under test 1.
