[0002] With the development of technology, early magnetic cards have been gradually replaced by smart cards. At present, smart cards are widely used in transportation, shopping, identity recognition and other fields. Smart cards can be divided into contact smart cards and contactless smart cards; contact smart cards need to be in contact with the card reader when used, so that the contact smart card can communicate with the card reader; contactless smart cards can be kept at a certain distance from the card reader when used, so that the contactless smart card can communicate with the card reader.

[0003] In the production process of smart cards, corresponding testing equipment is needed to perform bending tests, induction tests and other tests on smart cards. For example, the invention patent with patent application number 201510256606.6 provides a smart card breaking detection mechanism and a smart card performance detection system, including a limit device, a fixing table, a lifting device, a holding device and a first contactless detection mechanism; not only can the conduction status of the smart card under different deformation states be tested, but also the detection process can be simplified and the detection efficiency can be improved; when multiple items are detected at the same time, the operation is convenient and the efficiency is high; however, in actual applications, the following deficiencies still exist: the lack of waterproof detection leads to unreliable test results; if the waterproof performance is poor, the internal circuit of the smart card is easily damaged when it is immersed in water or in a high humidity environment for a long time, and finally the smart card fails.

[0020] The beneficial effects of the present invention are:

[0021] 1. This kind of card detection device conveys cards through a negative pressure adsorption belt line, uses an induction test mechanism 1 to conduct induction tests before and after the bending test. At the same time, the vacuum adsorption part and the batch bending part are used in cooperation to complete the batch bending test of the cards. The control mechanism and the movable clamping mechanism used in cooperation are used to fix the cards, and the rotating conveyor mechanism is used to send the cards into the water for waterproof testing. Before and after entering the water, the induction test mechanism 2 is used to conduct induction tests. It can not only automate the performance detection process, but also conduct multiple item detections simultaneously, so the detection efficiency is high. It also combines induction testing, bending testing, and waterproof testing together to make the detection results more reliable.

[0022] 2. This kind of card detection device drives the control seat to move downward through a control cylinder. After the rotating plug enters the rotating socket, the 90° rotator drives the control seat to rotate 90°, so that the movable clamping plate can avoid the rotating pressure block and move upward or press the movable clamping plate by means of the rotating pressure block. At most, only two sets of control mechanisms are needed to meet the feeding and discharging requirements during the waterproof test. Compared with the situation in the prior art where each fixture needs to be driven by a separate power source, it can save the use cost, and the control mechanism is fixed, which can not only avoid the occurrence of wire winding, but also reduce the use of pipelines, making the site cleaner.

[0023] 3. This kind of card detection device controls the rotating pressure block to rotate 90° by the control mechanism, so that the movable clamping plate can avoid the rotating pressure block. The movable clamping plate moves upward by means of the movable connection component. After the card is in place, the control seat driven by the control cylinder will press down the movable clamping plate, and the card is clamped by the movable clamping plate and the clamping frame. The control mechanism controls the rotating pressure block to rotate 90° again, and the rotating pressure block is used to press the movable clamping plate to complete the fixation of the card. At the same time, the overall structure is simple, which can not only reduce the burden on the rotating conveyor chain, but also be easy to implement. In addition, since the length of the telescopic rod is adjustable, it is applicable to clamping cards of different thicknesses, and the applicable range is wider.

[0024] 4. This kind of card detection device drives the folding bracket through a position regulator, and cooperates with the test fixture to complete the clamping operation of multiple cards at one time. The folding motor drives the driving rod, and through the transmission shaft 1, the transmission gear meshes with the sector gear to drive the transmission shaft 2 to rotate. The transmission shaft 2 drives the connected C-shaped bracket to rotate at an appropriate angle, so that the card bends upward or downward, and it can perform bending tests on multiple cards at one time to achieve batch detection.

[0025] 5. This kind of card detection device controls the movement of the air box through the adjustment mechanism, and moves the card between the upper clamping member and the lower clamping member. Since a plurality of vacuum suction cups 1 are provided, multiple cards can be sucked at one time, and when used in cooperation with the test fixture, it is beneficial to the batch testing of the cards.

[0026] 6. The card detection device adopts the induction test mechanism 1 and the induction test mechanism 2, which can not only perform non-contact induction tests, but also complete contact induction tests. There are two sets of both the induction test mechanism 1 and the induction test mechanism 2, so that it can complete induction tests and, after bending tests and waterproof tests, determine whether the card is a qualified product by comparing data, making the test results more reliable.

[0040] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are only for the purpose of illustrating and explaining the present invention, and are not intended to limit the present invention.

[0041] Embodiment: As Figure 1 , Figure 2 , Figure 3 and Fig. 9 shown, a card detection device of the present invention includes a test chamber 1. On both sides of the test chamber 1, there is a first induction test mechanism 2 for testing whether a card responds normally. Inside the test chamber 1, there is also a vacuum adsorption section 8 for batch adsorbing cards. Outside the vacuum adsorption section 8, there is a batch bending section for performing batch bending tests. The batch bending section is composed of a folding mechanism 10 for controlling the bending direction of the card and a test fixture 9 driven by the folding mechanism 10;

[0042] A negative pressure adsorption belt line 4 is used to convey cards. The test chamber 1 is installed on the top of the negative pressure adsorption belt line 4 frame. The cards are conveyed by the negative pressure adsorption belt line 4, which can reduce the probability of the card position being offset during the conveying process.

[0043] The waterproof testing part 3 arranged on one side of the negative pressure adsorption belt line 4 is composed of an open water tank 33, a rotating conveying mechanism arranged in the open water tank 33, a movable clamping mechanism 32 for fixing the card, and a control mechanism 34 for controlling the movable clamping mechanism 32 to clamp the card;

[0044] The induction test mechanism 2 7 is arranged at both ends of the open water tank 33, and the induction test mechanism 2 7 is used to test whether the card responds normally;

[0045] A transfer part 5 for transferring cards is arranged on the other side of the negative pressure adsorption belt line 4, and a rejection part 6 is arranged between the open water tank 33 and one of the induction test mechanisms 2, and the rejection part 6 is used to reject unqualified cards.

[0046] Among them, Figure 1 and Figure 2 As shown, the transfer part 5 is composed of a lifting column 51, an X-axis module 1, a Y-axis module 1, a lifting cylinder 52 and a vacuum suction cup 2 53. The X-axis module 1 is installed on the side of the moving body of the lifting column 51 with the help of an X-axis bracket 1. The Y-axis module 1 is connected to the moving body of the X-axis module 1 with the help of a Y-axis bracket 1. The lifting column 51 is used to adjust the height of the X-axis module 1. The vacuum suction cup 2 53 is installed on the piston end of the lifting cylinder 52. After the vacuum suction cup 2 53 sucks the card, the movement of the vacuum suction cup 2 53 is controlled by the X-axis module 1, the Y-axis module 1 and the lifting cylinder 52 to realize the card transfer operation.

[0047] Among them, Figure 1 and Figure 2 As shown, the rejection part 6 is composed of two lifting columns, two Y-axis modules, two lifting cylinders and three vacuum suction cups installed on the piston end of the two lifting cylinders. The two Y-axis modules and the two lifting cylinders are used to control the movement of the three vacuum suction cups. After the three vacuum suction cups suck the unqualified cards, the two Y-axis modules and the two lifting cylinders control the three vacuum suction cups that suck the unqualified cards to move to the top of the unqualified card collection box. After the three vacuum suction cups stop sucking, the unqualified cards automatically fall into the unqualified card collection box. In this embodiment, the unqualified card collection box adopts the existing technology and is therefore not marked in the accompanying drawings.

[0048] It should be noted that the transfer part 5 and the removal part 6 in this embodiment are just one implementation mode, and other implementation modes may also be adopted.

[0049] Among them, Figure 1-3 and Figure 5-7As shown, the rotating conveying mechanism includes a conveying frame 31 installed in an open water tank 33 and protruding from the open water tank 33, and a rotating conveying chain 35 arranged inside the conveying frame 31 and driven by a driving mechanism. The rotating conveying chain 35 is provided with a plurality of connecting brackets 36 protruding from the conveying frame 31 and used to support the movable clamping mechanism 32. The connecting brackets 36 are slidably connected to the conveying frame 31. The rotating conveying chain 35 driven by the driving mechanism rotates and moves the rotating conveying chain 35, and the connecting brackets 36 connected to the rotating conveying chain 35 drive the movable clamping mechanism 32 to move, so that the card can enter the open water tank 33 and be soaked in water.

[0050] Specifically, the movable clamping mechanism 32 includes a clamping frame 321, a movable clamping plate 322 arranged at one end of the clamping frame 321, and a movable connection component for connecting the clamping frame 321 and the movable clamping plate 322. The other end of the clamping frame 321 is provided with a mounting base plate 323 for connecting with the connecting bracket 36. A telescopic rod 324 is provided on the inner side of the clamping frame 321. A through hole 3212 is provided on the clamping frame 321 for accommodating the moving end of the telescopic rod 324 to pass through. A mounting blind hole 3213 for mounting the movable connection component is also provided on the clamping frame 321. A limit ring 3214 is installed in the mounting blind hole 3213. After the moving end of the telescopic rod 324 passes through the through hole 3212, it is rotatably connected to a rotating pressure block 325. A rotating plug 326 is provided on one side of the rotating pressure block 325. A bar-shaped through hole 3221 is provided on the movable clamping plate 322 for accommodating the rotating pressure block 325 to pass through.

[0051] The movable connection assembly consists of a T-shaped movable rod 328 slidably arranged in the installation blind hole 3213 and a connecting spring 329 installed in the installation blind hole 3213. One end of the T-shaped movable rod 328 passes through the limiting ring 3214 and is screwed to the movable clamping plate 322, and the other end is connected to the connecting spring 329.

[0052] The control mechanism 34 controls the rotating pressure block 325 to rotate 90°, so that the movable clamping plate 322 can avoid the rotating pressure block 325, so that the T-shaped movable rod 328 can move upward with the movable clamping plate 322 avoiding the rotating pressure block 325 with the help of the elastic force of the connecting spring 329. After the transfer part 5 places the card on the raised part of the clamping frame 321, the control seat 343 driven by the control cylinder 345 will press down the movable clamping plate 322, so that the T-shaped movable rod 328 presses down the connecting spring 329. After the movable clamping plate 322 and the clamping frame 321 clamp the card, the control mechanism 34 controls the rotating pressure block 325 to rotate 90° again, and uses the rotating pressure block 325 to press the movable clamping plate 322 to complete the fixation of the card. In addition, since the length of the telescopic rod 324 is adjustable, it is suitable for clamping cards of different thicknesses.

[0053] Specifically, a weight-reducing hole 3211 is provided on the clamping frame 321 , and the weight-reducing hole 3211 can reduce the weight of the clamping frame 321 , thereby reducing the burden on the rotating conveyor chain 35 , and the setting of the weight-reducing hole 3211 can also facilitate workers to adjust the length of the telescopic rod 324 .

[0054] Specifically, both the clamping frame 321 and the movable clamping plate 322 are provided with a protrusion for clamping the card, and an anti-skid elastic pad 327 is provided on the outer side of the protrusion. The anti-skid elastic pad 327 can increase the friction between the card and reduce the probability of damage to the card surface.

[0055] Among them, Figure 2 , Figure 3 , Figure 5 and Figure 8 As shown, the control mechanism 34 includes a control cylinder 345 and a mounting bracket 341 for supporting the control cylinder 345. The mounting bracket 341 is installed on the top of the open water tank 33. The piston rod of the control cylinder 345 is connected to the control bracket 342. The upper and lower sides of the top plate of the control bracket 342 are respectively provided with a 90° rotator 344 and a control seat 343. The top of the control seat 343 is connected to the output end of the 90° rotator 344. The bottom of the control seat 343 is provided with a rotating hole 3431 matching the rotating pressure block 325. The top of the rotating hole 3431 is connected to a rotating jack matching the rotating plug 326. The cooperation between the rotating pressure block 325 and the rotating hole 3431 plays a positioning role.

[0056] The control seat 343 is driven to move downward by the control cylinder 345. After the rotating plug 326 enters the rotating socket, the 90° rotator 344 drives the control seat 343 to rotate 90°, so that the movable clamping plate 322 can avoid the rotating pressure block 325 and move upward, or use the rotating pressure block 325 to press the movable clamping plate 322. Only one set of common control mechanisms 34 is needed to complete the loading and unloading during the waterproof test. No other power source is needed, which can save the use cost.

[0057] In addition, in order to speed up the testing efficiency, a set of control mechanisms 34 can be flexibly added to separate loading and unloading. Only two sets are needed at most to meet the usage requirements. Compared with the prior art where each fixture requires a separate power source to drive, the usage cost can be saved. The control mechanism 34 is fixed, which can not only avoid the occurrence of wire winding, but also reduce the use of pipelines, making the site tidier.

[0058] Among them, Figure 1-4As shown, the inductive testing mechanism 2 7 is composed of a supporting column 71, a sliding seat 73 slidably mounted on the supporting column 71, a supporting frame 72 for supporting the supporting column 71, and an inductive tester 2 75 for detecting the card. The supporting frame 72 is installed on the top of the open water tank 33, and a test cylinder 74 is provided on the top of the sliding seat 73. The piston rod of the test cylinder 74 is connected to a supporting plate 76 for supporting the inductive tester 2 75.

[0059] After adjusting the height of the sliding seat 73 and the card is moved to one side of the inductive tester 75, the inductive tester 75 is driven by the test cylinder 74 to adjust the distance between the inductive tester 75 and the card, thereby not only non-contact inductive testing but also contact inductive testing can be performed.

[0060] In addition, the induction test mechanism 27 is provided with two groups, which can judge whether the waterproof performance of the card meets the requirements by comparing the data before and after entering the water, such as the response time of the card and whether the card responds.

[0061] It should be noted that the inductive tester 2 75 can be a card reader, which should be matched with the card to be tested and can work normally, that is, the inductive tester 2 75 should be able to read the card to be tested normally to improve the detection accuracy.

[0062] In addition, the sliding seat 73 is locked by a locking device, and the locking device can be a locking bolt, or other embodiments can be adopted.

[0063] Among them, Figure 9-11 As shown, the folding mechanism 10 includes a position regulator 108 installed inside the test chamber 1 via a supporting bracket and a folding bracket 103 connected to the moving end of the position regulator 108, a folding motor 101 is installed on the inner side of the folding bracket 103, the output shaft of the folding motor 101 is connected to the driving rod 102, and a transmission shaft 105 and a transmission shaft 2 104 are provided on the inner side of the folding bracket 103, which are connected to the driving rod 102 through a transmission belt, and both ends of the transmission shaft 105 and the transmission shaft 2 104 are connected to the folding bracket 103 through bearings, and transmission gears 107 are fixedly sleeved on the outer walls of both ends of the transmission shaft 105, and fan gears 106 meshingly connected to the transmission gear 107 are fixedly sleeved on the outer walls of both ends of the transmission shaft 104.

[0064] The folding bracket 103 is driven by the position regulator 108 to cooperate with the test fixture 9 to complete the clamping operation of the card. The folding motor 101 drives the driving rod 102, and the transmission belt is used to drive the first transmission shaft 105 to drive the transmission gear 107 to mesh with the sector gear 106 for transmission, so that the second transmission shaft 104 rotates. The second transmission shaft 104 is used to drive the connected C-shaped bracket 94 to rotate at an appropriate angle, so that the card bends upward or downward. At the same time, in cooperation with the test fixture 9, multiple cards can be bent and tested at one time, realizing batch detection.

[0065] Among them, as Figure 9-11 shown, the test fixture 9 includes two C-shaped brackets 94 arranged face to face, two clamping cylinders 97 installed on one side of the C-shaped bracket 94, a moving clamping plate 92 connected to the piston rod of the clamping cylinder 97, and two transmission parts 93 sleeved and fixed outside the second transmission shaft 104 and symmetrically distributed. The C-shaped bracket 94 and the moving clamping plate 92 are respectively provided with a lower clamping part 95 and an upper clamping part 96 for clamping the card. One side of one C-shaped bracket 94 is symmetrically provided with a fixed bracket 91, and the fixed bracket 91 is installed on the top of the frame of the negative pressure adsorption belt line 4. The other C-shaped bracket 94 is fixedly connected to the transmission part 93. Elastic pads are also provided at the positions where the lower clamping part 95 and the upper clamping part 96 clamp the card, which has the same function as the anti-slip elastic pad 327.

[0066] When the card is placed between the upper clamping part 96 and the lower clamping part 95, the moving clamping plate 92 is controlled to move downward by the clamping cylinder 97, and the card is clamped by the upper clamping part 96 and the lower clamping part 95. Since there are multiple upper clamping parts 96 and lower clamping parts 95, batch clamping of the cards can be completed.

[0067] Among them, as Fig. 9 shown, the first induction test mechanism 2 includes a picking mechanism 22 for picking up the card and an induction bin 21 for supporting the picking mechanism 22. The induction bin 21 is installed on the top of the frame of the negative pressure adsorption belt line 4. An induction tester 23 for detecting the card is installed in the induction bin 21. The picking mechanism 22 is used to pick up the card transported by the negative pressure adsorption belt line 4 and adjust the distance between the card and the induction tester 23 for non-contact induction testing or contact induction testing. Since two groups of the first induction test mechanisms 2 are provided, the test data of the two groups of the first induction test mechanisms 2, such as response time, whether to respond, etc., can also be compared to determine whether the card after bending is a qualified product.

[0068] It should be noted that while the picking mechanism 22 can pick up the card, it should also be able to adjust the angle of the card to facilitate the induction test of the card. The specific structure of the picking mechanism 22 is not limited here.

[0069] Among them, as Fig. 9As shown, the vacuum adsorption part 8 includes an air box 82 and an adjusting mechanism 81 installed inside the test chamber 1 and used to adjust the position of the air box 82. A plurality of shunt interfaces are communicated at the bottom of the air box 82, and a first vacuum suction cup 83 is screwed at the bottom of the shunt interface. After the first vacuum suction cup 83 sucks the card, the movement of the air box 82 is controlled by the adjusting mechanism 81 to move the card between the upper clamping member 96 and the lower clamping member 95. Since a plurality of first vacuum suction cups 83 are provided, multiple cards can be sucked at one time, and when used in cooperation with the test fixture 9, it is beneficial to perform batch testing of the cards.

[0070] In addition, the adjusting mechanism 81 can be a structure composed of an X-axis module, a Y-axis module, and a Z-axis module that can drive the air box 82, and finally drive the first vacuum suction cup 83, which is beneficial for the first vacuum suction cup 83 to suck the card. This is one implementation manner, and other implementation manners can also be adopted.

[0071] During operation, the card is conveyed by the negative pressure adsorption belt line 4. Before entering the test chamber 1, it is subjected to induction testing through the first induction testing mechanism 2. When the card enters the test chamber 1 and the first vacuum suction cup 83 sucks the card, the movement of the air box 82 is controlled by the adjusting mechanism 81 to move the card. The moving clamping plate 92 is controlled to move downward by the clamping cylinder 97, and the upper clamping member 96 and the lower clamping member 95 are used to clamp the card from one end. The folding bracket 103 is driven by the position adjuster 108 to approach the card. After the other end of the card is also clamped, the folding motor 101 is started, and the driving rod 102 drives the transmission shaft 105 through the transmission belt to drive the transmission gear 107 to mesh with the sector gear 106 for transmission, controlling the rotation of the transmission shaft 104. The transmission shaft 104 is used to drive the connected U-shaped bracket 94 to rotate by an appropriate angle to bend the card upward or downward for bending testing. After the testing is completed, the vacuum adsorption part 8 returns the card to the negative pressure adsorption belt line 4. When passing through another induction chamber 21, induction testing is performed again to detect whether the card fails. The failed card is removed by the removal part 6. The card passing the bending testing is transferred by the transfer part 5. The control mechanism 34 is used to control the movable clamping mechanism 32 to fix the card, and the rotating conveyor chain 35 driven by the driving mechanism is used to convey the card to make the card enter the water for waterproof testing. Before and after entering the water, induction testing is performed through the second induction testing mechanism 7 to detect whether the card fails. The failed card can be removed by the transfer part 5.
