However, the existing SIM card detection, identification and classification operations are all performed manually. In actual operation, the operator first inserts a single SIM card into the SIM card detection terminal. The SIM card detection terminal can read the information of the SIM card and determine whether the card functions normally. If the card functions normally, it is judged as a good card and is placed in the corresponding storage box. If the card is damaged and cannot be used, it is judged as a bad card and is placed in a storage box specially used for bad cards. The above operation methods all need to be completed manually.

[0049] In order to explain the technical content, structural features, achieved objectives and effects of the technical solution in detail, the following is a detailed description in conjunction with specific embodiments and accompanying drawings.

[0050] See also Fig.12 In this application, A of the SIM card is length and B is width.

[0051] See also Figures 1 to 12 The present application discloses a SIM card chain mechanism 10, comprising: a plurality of chain bins 11, a transmission member 12, a turntable 13, a driving shaft 14 and a driven shaft 15; each of the chain bins 11 is provided with a first cavity 111 for accommodating a SIM card, and the chain bin 11 is provided with two first SIM card ports 112, the two first SIM card ports 112 are arranged opposite to each other, and the two first SIM card ports 112 are connected to the first cavity 111; the driving shaft 14 is parallel to the driven shaft 15; a plurality of The chain bin 11 is placed on the transmission member 12, and the driving shaft 14 and the driven shaft 15 are respectively provided with a turntable 13, and the turntable 13 on the driving shaft 14 is transmission-connected with the turntable 13 on the driven shaft 15 through the transmission member 12; a reset detection mechanism is also provided on the chain mechanism; the reset detection mechanism includes: a circle counting device and a positioning device 161; the circle counting device is sleeved on the driving shaft, and the positioning device 161 is placed on the brackets of the chain bin and the chain mechanism.

[0052] It should be noted that the driving rotating shaft 14 and the driven rotating shaft 15 are at a certain distance from each other, and the two turntables 13 are on the same horizontal plane. The transmission member 12 is mounted on the two turntables 13, so that the transmission member 12 forms an oval shape, and the movement trajectory of the chain bin 11 is also an oval shape; a plurality of chain bins 11 are arranged along the outer edge of the transmission member 12, each of the chain bins 11 can only store one SIM card, and the chain bins 11 are used to transport SIM cards.

[0053] It should also be noted that the active shaft 14 is connected to the output end of the motor, that is, the active shaft 14 is sleeved on the output end of the motor, and the output end of the motor will drive the active shaft 14 to rotate, thereby driving the turntable 13 on the active shaft 14 to rotate, and further driving the transmission member 12 and the driven shaft 15 to rotate. It should also be further noted that in this embodiment, a positioning part is provided on one of the chain bins 11, preferably, the positioning part is a positioning hole, and a proximity sensor 1611 is provided above the motion trajectory of the chain bin 11, and the proximity sensor 1611 is used to sense the positioning part; specifically, when the proximity sensor senses the positioning part and the infrared sensor senses the gap, the chain bin is at an absolute zero point, that is, when it needs to be reset, the active shaft 14 drives the chain bin 11 to rotate, so that the chain bin 11 with the positioning part moves to below the proximity sensor 1611, so that the proximity sensor 1611 is directly opposite to the positioning part, and the gap is placed below the infrared sensor. Of course, the reset detection mechanism 16 can also play the role of recording the number of circles run by the chain mechanism 10. When the alignment device 161 and the circle counting device simultaneously sense a specific point, the reset operation is completed at this time. It should also be noted that the moving distance of the chain bin is related to the rotation angle of the active shaft, that is, the active shaft rotates a certain degree, and the chain bin moves a certain distance. However, the circle counting device only provides and records integer circles, and cannot provide and record half circles or other circles. At the same time, the length of the transmission member / the circumference of the turntable ≠ integer. Specifically, when restarting in the event of a fault, if it is an integer, no matter how many circles are rotated, it will be located at a certain point and the reset operation cannot be completed.

[0054] In actual operation, when the chain bin 11 in the chain mechanism 10 is out of position and cannot normally receive the SIM card, the active shaft 14 drives the chain bin 11 with the alignment portion to move to the absolute zero point, at which time the chain mechanism 10 is in the initial state, and the chain bin 11 can be used normally. When the device suddenly loses power and is restarted, the device can be reset to the initial state, and then the chain bin 11 can be moved to the operating position before the power failure through the operation record recorded in the control unit.

[0055] The above technical solution improves the transmission efficiency of the SIM card through the chain bin 11, the transmission member 12, the active shaft 14 and the driven shaft 15; at the same time, the reset detection mechanism 16 enables the card chain mechanism 10 to continue to complete the operation after a failure occurs.

[0056] See also Figure 4 and Figure 5, the reset detection mechanism also includes: a circle counting device; in this embodiment, a circle counting device 162 is provided on the active rotating shaft 14 or the driven rotating shaft 15, and the circle counting device 162 is used to record the number of circles rotated by the active rotating shaft 14 or the driven rotating shaft 15; the circle counting device 162 includes: a counting disk 1621 and an infrared sensor 1622; the counting disk 1621 is sleeved on the active rotating shaft 14 or the driven rotating shaft 15, and is located above the rotating disk 13; a notch is provided on the counting disk 1621, and the infrared sensor 1622 is used to detect the notch on the counting disk 1621. It should be noted that the notch is placed on the edge of the counting disk 1621, and the infrared sensor 1622 is placed on one side of the counting disk. The infrared sensor 1622 is used to sense the number of times the gap is passed and record it, and the counting disk 1621 rotates a number of times corresponding to the distance that the chain bin 11 travels one circle; of course, in some embodiments, the value of the transmission member length divided by the circumference of the turntable may not be an integer.

[0057] Specifically, when the chain mechanism 10 is in the initial state, the infrared sensor 1622 just shines into the gap. After the active shaft 14 starts to rotate, the chain bin 11 starts to move. Each time the infrared sensor 1622 detects the gap, that is, the active shaft 14 rotates one circle, the count of the counting disk 1621 changes, and the total number of circles recorded by the control unit will increase by one circle; of course, in some embodiments, if the rotation is forward, each time the infrared sensor 1622 detects the gap, the total number of circles recorded by the control unit will increase by one circle; if the rotation is reversed, each time the infrared sensor 1622 detects the gap, the total number of circles recorded by the control unit will decrease by one circle.

[0058] It should also be noted that the number of chain bin unit lengths that the chain bin moves is controlled by the angle of rotation of the active shaft. It should also be noted that when the infrared sensor faces the notch and the proximity sensor faces the alignment portion, the chain bin is at an absolute zero point, that is, in a reset state.

[0059] In actual operation, when the chain mechanism 10 fails and stops working, the chain mechanism 10 starts to perform a reset operation to put the chain mechanism 10 in an initial state. At this time, the proximity sensor 1611 senses the alignment part, and the infrared sensor senses the gap. Then, the control unit records the number of rotations of the counting disk 1621, so that the chain bin 11 moves to the operating position before the failure occurs. In some embodiments, during the operation of the chain mechanism 10, the control unit may also record the number of rotations of the counting disk. When the chain mechanism 10 fails, the control unit moves the chain bin 11 to the position before the failure according to the recorded number of rotations. It should also be noted that the number of rotations includes the number of forward rotations and the number of reverse rotations.

[0060] See also Figure 4 and Figure 5 In some embodiments, the reset detection mechanism also includes: the alignment device 161 includes: a proximity sensor and an alignment part; the alignment part is placed on the chain bin, and only one of the multiple chain bins has the alignment part; the proximity sensor is used to detect the alignment part.

[0061] See also Figure 1 , Figure 2 , Figure 3 and Figure 8 In this embodiment, a card slot structure 20 is provided on one side of the card chain mechanism 10. The card slot structure 20 is used to accommodate multiple SIM cards. A second SIM card port 21 is also provided on the card slot structure 20. The second SIM card port 21 is used for the SIM card to enter and exit. When the SIM card is moved from the card slot structure 20 to the chain slot 11 or when the SIM card is moved from the chain slot 11 to the card slot structure 20, the first SIM card port 112 is directly opposite to the second SIM card port 21, and the distance between the first SIM card port 112 and the second SIM card port 21 is less than the length or width of the SIM card. It should be noted that there are multiple card slot structures 20 provided on one side of the card chain mechanism 10, each of which is used to accommodate multiple SIM cards, and the multiple card slot structures 20 are divided into an archive area and an unarchived area, and the card chain device is used to move the SIM card in the unarchived area to the archive area. And the card slot structure 20 is placed above the card chain mechanism 10.

[0062] It should be noted that the unarchived area refers to the area where the SIM cards in the card compartment structure 20 have not been identified and classified, while the archived area refers to the area where the SIM cards in the card compartment structure 20 have been identified and classified, and the same type of SIM cards are placed in the same card compartment structure 20; specifically, the chain compartment 11 structure is used to move the SIM cards that have not been sorted to the corresponding card compartment structure 20 after identification and classification. It should also be noted that the chain compartment 11 has a detection mechanism 30 that can identify the SIM card; when the SIM card is located in the chain compartment 11, the detection mechanism 30 identifies the SIM card and transmits the identification data to the control unit in a wireless or wired manner, and the control unit drives the chain compartment 11 to move to the bottom of the corresponding card compartment structure 20, and moves the SIM card to the corresponding card compartment structure 20 through the pick-and-place structure 40.

[0063] It should be further explained that, in order to prevent the SIM card from falling when it is moved from the card compartment structure 20 to the chain compartment 11 or from the chain compartment 11 to the card compartment structure 20, the distance between the first SIM card port and the second SIM card port 21 is smaller than the length or width of the SIM card; that is, before the SIM card is completely out of the first SIM card port 112, the end of the SIM card that first exits the first SIM card port 112 enters the second SIM card port 21. The distance between the first SIM card port 112 and the second SIM card port 21 is very small, that is, when the SIM card is just pushed out of the second SIM card port 21, it immediately enters the first SIM card port 112.

[0064] In actual use, when the SIM card needs to be moved from the card compartment structure 20 in the unarchived area to the archived area, the active shaft 14 rotates and drives the transmission member 12 and the chain compartment 11 to move, and the chain compartment 11 will be placed below the second SIM card port 21. At this time, the first SIM card port 112 is facing the second SIM card port 21, and the SIM card will enter the chain compartment 11 through the second SIM card port 21 and the first SIM card port 112 in sequence; after identification and detection by the detection mechanism 30, the active shaft 14 will drive the chain compartment 11 to rotate again, and the chain compartment 11 will be moved to below the card compartment structure 20 in the archived area. At this time, the first SIM card port 112 is facing the second SIM card port 21, and the SIM card will enter the card compartment structure 20 through the first SIM card port 112 and the second SIM card port in sequence, completing the sorting and classification of the SIM cards.

[0065] See also Figure 5 and Figure 6In some embodiments, the transmission member 12 is a chain, and the turntables 13 on the driving shaft 14 and the driven shaft 15 are sprockets, and the sprockets are adapted to the chain. It should be noted that the adaptation of the sprockets to the chain can prevent the transmission member 12 and the turntable 13 from slipping during transmission, while improving the accuracy of the counting of the circle counting device 162. Of course, in some implementations, the transmission member 12 is a belt, and the turntables on the driving shaft 14 and the driven shaft 15 are used to drive the belt to rotate, and the sprockets are adapted to the chain.

[0066] See also Figures 5 to 7 In order to facilitate SIM card detection, a through hole 113 is further provided on the side wall of the chain compartment 11. The through hole 113 is connected to the first cavity 111. When the SIM card is in the chain compartment 11, the chip of the SIM card is exposed at the bottom of the through hole 113. Specifically, when the SIM card is placed in the chain compartment 11, the chip on the SIM card is exposed at the bottom of the through hole 113, which is convenient for detection. Please refer to Fig.10 In another embodiment, a detection mechanism 30 is further provided on one side of the through hole 113, and the detection mechanism 30 includes: a second driving device 31 and a probe module 32; the probe module 32 is connected to the second driving device 31, and the probe module 32 is aligned with the through hole 113, and the second driving device 31 is used to drive the probe module 32 to move toward or away from the SIM card.

[0067] It should be noted that the probe module 32 is in the same horizontal plane as the through hole 113, that is, the probe module 32 can detect and identify the chip on the SIM card only by horizontal movement. When the SIM card moves into the chain bin 11, the detection mechanism 30 will detect the SIM card in the chain bin 11; specifically, the second driving device 31 drives the probe module 32 to move toward the chip, and the probe on the probe module 32 passes through the through hole 113 and contacts the chip to start reading data.

[0068] See also Fig.11 In some embodiments, the width of the first SIM card port 112 is smaller than the width of the SIM card, and the lower card pin is adapted to the second SIM card port 21. When the SIM card is pushed into the chain compartment 11, the SIM card will be blocked by the first SIM card port 112. Of course, in some embodiments, a limit block is also provided in the chain compartment 11; that is, a limit block is provided below the preset position of the SIM card; the limit block prevents the SIM card from exceeding the preset position when moving downward; the limit block and the limitation of the width of the first SIM card are used to prevent the SIM card from being misplaced during the downward movement.

[0069] See also Fig. 9In some embodiments, a pick-and-place structure 40 is further provided on one side of the card chain mechanism 10; there are multiple pick-and-place structures, and the pick-and-place structures correspond to the card magazine structures one by one. The pick-and-place structure 40 includes: an upper push pin 41, a lower push pin 42 and a first drive device 43; the pick-and-place structure 40 is placed at the end of the card compartment structure 20 and is located at one end of the card compartment structure 20 close to the front cover; the upper push pin 41 faces one of the second SIM card ports 21, the lower push pin 42 faces another of the second SIM card ports 21, and the upper push pin 41 and the lower push pin 42 are used to load and eject the SIM card respectively; the upper push pin 41 and the lower push pin 42 are connected by a connecting rod 44, the first drive device 43 is connected to the connecting rod 44, and the first drive device 43 is used to drive the rod connection to move upward or downward; when the SIM card moves from the card compartment structure 20 to the chain compartment 11 or when the SIM card moves from the chain compartment 11 to the card compartment structure 20, the upper push pin 41 faces one of the first SIM card ports 112, and the lower push pin 42 faces another of the first SIM card ports 112. The first drive device 43 is a steering gear. It should be noted that the card compartment structure 20 is provided with two second SIM card ports 21, and the two second SIM card ports 21 are arranged opposite to each other, one of the second SIM card ports 21 is used for loading and ejecting the SIM card, that is, the SIM card enters and exits from the second SIM card port 21; the other second SIM card port 21 is used for the upper push pin 41 to enter and exit. When the SIM card needs to be moved from the card compartment structure 20 to the chain compartment 11, the upper push pin 41 will move downward to push out the SIM card in the card compartment structure 20. The lower push pin 42 is used to push the SIM card in the chain compartment 11 into the card compartment structure 20; when the SIM card needs to be moved from the chain compartment 11 to the card compartment structure 20, the first driving device drives the connecting rod 44 to move upward, and the lower push pin 42 will also move upward to push out the SIM card in the chain compartment 11. The size and shape of the upper push pin 41 and the lower push pin 42 are adapted to the first SIM card port 112 and the second SIM card port 21 , and the upper push pin 41 and the lower push pin 42 can both enter and exit from the first SIM card port 112 and the second SIM card port 21 .

[0070] The present application also provides a driving method for a SIM card chain mechanism, and the driving method for a SIM card chain mechanism 10 is applied to any embodiment of the SIM card chain mechanism 10; the SIM card chain mechanism 10 also includes a control unit, the control unit is electrically connected to the chain mechanism 10, the detection mechanism 30, the pick-and-place structure 40, the reset detection mechanism 16 and the circle counting device 162, and the control unit is used to drive the chain mechanism 10, the detection mechanism 30, the pick-and-place structure 40, the reset detection mechanism 16 and the circle counting device 162; comprising the steps of:

[0071] The driving unit drives the chain mechanism 10 to rotate, so that the chain bin 11 is placed below the bin structure 20;

[0072] The pick-and-place structure 40 is driven to move downward to push the SIM card in the card compartment structure 20 into the chain compartment 11;

[0073] The card chain mechanism 10 is driven to rotate, so that the chain bin 11 with the SIM card moves to the detection position;

[0074] The detection mechanism 30 is driven to move toward the direction close to the chain bin 11 to read the data on the SIM card, and after reading the data, the detection mechanism 30 is driven to move toward the direction away from the chain bin 11;

[0075] The card chain mechanism 10 is driven to rotate, so that the chain compartment 11 with the SIM card moves to the bottom of the corresponding card compartment structure 20;

[0076] The pick-and-place structure 40 is driven to move upward to push the SIM card in the chain bin 11 into the card bin structure 20 .

[0077] In some embodiments, the steps are further included:

[0078] When the chain mechanism 10 rotates, the control unit records the number of rotations of the chain mechanism 10 through the reset detection mechanism 16 and the rotation counting device 162 .

[0079] In actual use, when the SIM card needs to be moved from the card slot structure 20 in the unarchived area to the archived area, the active shaft 14 rotates and drives the transmission member 12 and the chain slot 11 to move, and the chain slot 11 will be placed below the second SIM card port 21. At this time, the first SIM card port 112 is directly opposite to the second SIM card port 21; at this time, the first driving device 43 drives the push pin 41 to move downward, so that the SIM card will pass through the second SIM card port 21 and the first SIM card port in turn and enter the chain slot 11; at this time, the second driving device 31 drives the probe module 31 to move downward. The block 32 moves toward the chip and identifies the chip located at the bottom of the through hole 113. After identification and detection by the detection mechanism 30, the active shaft 14 will drive the chain bin 11 to rotate again, and the chain bin 11 moves to below the card bin structure 20 in the filing area. At this time, the first SIM card port 112 is facing the second SIM card port 21. At this time, the first driving device 43 drives the push pin 42 to move upward, so that the SIM card will pass through the first SIM card port 112 and the second SIM card port 21 in turn into the card bin structure 20, completing the sorting and classification of the SIM cards.

[0080] In actual operation, when the chain bin 11 in the chain mechanism 10 is out of position and cannot normally receive the SIM card, the active shaft 14 drives the chain bin 11 with the alignment portion to move to the absolute zero point, at which time the chain mechanism 10 is in the initial state, and the chain bin 11 can be used. When the device suddenly loses power and is restarted, the device can be reset to the initial state, and then the chain bin 11 can be moved to the operating position when the power is lost by the number of step pulses recorded in the control unit.

[0081] It should be noted that when the chain mechanism 10 fails and stops working, the chain mechanism 10 starts to perform a reset operation to put the chain mechanism 10 in an initial state. At this time, the alignment portion is placed below the proximity sensor 1611, and the gap is located below the infrared sensor. Then, the number of step pulses recorded by the control unit moves the chain bin 11 to the working position before the failure occurs; specifically, during the operation of the chain mechanism 10, the control unit records the number of revolutions of the counting disk. When the chain mechanism 10 fails, the control unit moves the chain bin 11 to the position before the failure according to the recorded number of revolutions. It should also be noted that the number of revolutions includes the number of forward revolutions and the number of reverse revolutions.

[0082] It should be noted that, although the above embodiments have been described in this article, the patent protection scope of the present invention is not limited thereby. Therefore, based on the innovative concept of the present invention, changes and modifications made to the embodiments described herein, or equivalent structures or equivalent process changes made using the contents of the present invention specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included in the patent protection scope of the present invention.
