Description

Technical Field

[0001] This invention relates to the field of card detection equipment technology, and in particular to a card detection device and its detection method. Background Technology

[0002] In existing technologies, after the identification cards are produced, they need to undergo multi-condition filtering of elements such as the overall image, conference logo, conference name, name and photo, work unit, one-dimensional barcode, two-dimensional barcode, and serial number. Furthermore, the chip number of the current identification card needs to be read and recorded. However, currently, the inspection of the appearance and code verification function of identification cards is mainly done manually, with some automated card issuing equipment used. Manual card placement is time-consuming and labor-intensive, significantly reducing inspection efficiency. Automated card issuing equipment has a complex structure and cannot adapt to various card sizes due to differences in card dimensions. Moreover, existing card issuing equipment is prone to card flipping during distribution, leading to subsequent false detections and greatly affecting the accuracy of the equipment's inspection. Therefore, there is an urgent need for a device that can reduce the false detection rate and simultaneously perform quality inspection and code verification functions for identification cards of different sizes. Summary of the Invention

[0003] This solution addresses the problems and needs raised above by proposing a card detection device and its detection method. Due to the adoption of the following technical features, it can achieve the above-mentioned technical objectives and bring about several other technical effects.

[0004] One object of the present invention is to provide a card detection device, comprising: A card issuing mechanism includes: a base frame and a hopper, a drive unit, and a conveying unit connected to the base frame. The hopper is configured to stack and store cards of different sizes to be tested. The drive unit is configured to drive the cards to be tested stacked in the hopper to the conveying unit one by one. The conveying unit is configured to convey the cards to be tested conveyed by the drive unit. A conveyor mechanism, located downstream of the conveyor section, is configured to receive the cards to be inspected from the conveyor section and continue to convey them to a designated location. The detection mechanism is located on one side of the conveyor line mechanism and is configured to detect whether the information of the card to be detected on the conveyor line mechanism is qualified, and to remove the card to be detected if it is unqualified.

Under the action of the adjustment assembly, at least one of the first side plate and the second side plate moves closer to or further away from the other.

[0006] In one example of the present invention, the adjustment assembly includes a first screw, a second screw, and a knob, the knob being fixedly connected to the first screw and the second screw; A first threaded hole is provided on the first side plate, and the first screw is engaged with the first threaded hole; A second threaded hole is provided on the second side plate, and the second screw is engaged with the second threaded hole; The first threaded hole and the second threaded hole have opposite thread directions, and the first screw and the second screw have opposite thread directions.

[0007] In one example of the present invention, In the first side plate and the adjustment assembly, one is provided with a first slide rail, and the other is provided with a first sliding rod, the first sliding rod moving along the first slide rail; In the second side plate and the adjustment assembly, one is provided with a second slide rail, and the other is provided with a second sliding rod, which moves along the second slide rail; The adjustment assembly further includes a first limiting component and a second limiting component. The first limiting component is used to limit the relative movement between the first sliding rod and the first slide rail, and the second limiting component is used to limit the relative movement between the second sliding rod and the second slide rail.

[0008] In one example of the present invention, The first sliding rod is provided with a first protrusion, and the first slide rail is provided with a plurality of first recesses. The first protrusion is engaged with any of the first recesses. The first limiting component includes the first protrusion and the first recesses. The second sliding rod is provided with a second protrusion, and the second slide rail is provided with a plurality of second recesses. The second protrusion is engaged with any of the second recesses, and the second limiting component includes the second protrusion and the second recesses.

[0009] In one example of the present invention, the drive unit includes: a guide plate and a conveyor belt assembly. The guide plate is connected to the bracket and is located at the upper end of the conveyor belt assembly; A cavity is formed between the conveyor belt assembly and the guide plate. Under the driving action of the conveyor belt assembly, the cards to be tested are guided into the cavity one by one by the guide plate. The span of the cavity is the same as the thickness of the card to be tested.

[0010] In one example of the present invention, the guide plate includes: a straight plate portion and an arcuate portion connected thereto, the straight plate portion being used to stop the cards to be tested stacked on the conveyor belt assembly, the arcuate portion being disposed opposite to the conveyor belt assembly, and its bending direction being consistent with the transmission direction of the conveyor belt assembly, configured to guide the cards to be tested one by one into the clamping cavity.

[0011] In one example of the present invention, the drive unit further includes a support wheel connected to the base frame and disposed on one side of the guide plate, wherein the outer contour curvature of the support wheel is consistent with the curvature of the arc-shaped portion.

[0012] In one example of the present invention, the conveying section includes: two guide wheel assemblies arranged in parallel on the base frame, with a conveying cavity for conveying the card to be tested formed between the two guide wheel assemblies; The guide wheel assembly includes: a drive motor, multiple rotating shafts, multiple rollers, and a belt.

[0013] Another object of the present invention is to provide a detection method for the card detection device described above, comprising the following steps: The cards to be tested are stacked in the hopper section. The drive unit drives the cards to be tested in the hopper section to the conveyor section. During this process, under the driving action of the conveyor belt assembly, the cards to be tested stacked in the hopper section are guided by the guide plate and enter the clamping cavity one by one from the bottom up. Then the conveyor section transports the cards to be tested to the conveyor line mechanism. The inspection agency checks the appearance and RFID code of the cards to be inspected on the conveyor line mechanism to determine whether they are qualified. If a card is unqualified, it is rejected. Qualified cards flow into the turnover box.

The card issuing mechanism of this invention has a simple structure and can adapt to issuing cards of different sizes. Furthermore, the initial arrangement of the cards to be inspected only requires stacking them flat to efficiently distribute them sequentially, greatly improving issuing efficiency and saving manpower and resources. The clamping and conveying cavities used in the card issuing mechanism effectively prevent cards from flipping during transport, thus effectively preventing subsequent inspection mechanisms from failing to identify the cards and causing mis-inspections. This card inspection device not only improves the quality inspection efficiency of the card production line but also reduces labor costs and error rates, bringing great convenience to production and management.

[0021] According to a first aspect of the present invention, a card detection device 1000, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7 As shown, it includes: The card issuing mechanism 100 includes: a base frame 40 and a hopper 10, a drive unit 20, and a conveying unit 30 connected to the base frame 40. The hopper 10 is configured to stack and store cards 200 of different sizes to be tested. The drive unit 20 is configured to drive the cards 200 stacked in the hopper 10 to the conveying unit 30 one by one. The conveying unit 30 is configured to convey the cards 200 conveyed by the drive unit 20. The conveyor mechanism 200 is located downstream of the conveyor section 30 and is configured to receive the card to be tested 200 from the conveyor section 30 and continue to convey it to a designated location. The detection mechanism 300 is located on one side of the conveyor line mechanism 200 and is configured to detect whether the information of the card to be tested 200 located on the conveyor line mechanism 200 is qualified, and to remove the card to be tested 200 if it is unqualified.

[0022] The working principle of the card detection device 1000 is as follows: The card to be detected 200 is placed in the hopper section 10. The drive section 20 drives the card to be detected 200 in the hopper section 10 to the conveyor section 30. During this process, under the driving action of the conveyor belt assembly 22, the cards to be detected 200 stacked in the hopper section 10 are guided by the guide plate 21 and enter the clamping cavity 23 one by one from the bottom up. Then, the conveyor section 30 conveys the card to be detected 200 to the conveyor line mechanism 200. The detection mechanism 300 detects whether the appearance and RFID code of the card to be detected 200 on the conveyor line mechanism 200 are qualified. If the card to be detected is unqualified, it is rejected. The qualified cards to be detected flow into the turnover box. The card inspection device 1000 achieves rapid sorting and rejection of cards 200 to be inspected by constructing a card issuing mechanism 100, a conveyor line mechanism 200, and an inspection mechanism 300, thus realizing efficient and accurate inspection of card quality. The card inspection device 1000 not only improves the quality inspection efficiency of the card production line, but also reduces labor costs and error rates, bringing great convenience to production and management.

[0023] This card inspection device uses a card issuing mechanism to sequentially distribute cards onto a conveyor line, where an inspection mechanism quickly sorts and rejects the cards, achieving efficient and accurate quality control. The card issuing mechanism is simple in structure and adaptable to different card sizes. Initially, the cards only need to be stacked flat to efficiently distribute them sequentially, significantly improving efficiency and saving manpower and resources. The clamping and conveying cavities effectively prevent cards from flipping during transport, thus avoiding misidentification by the subsequent inspection mechanism. This card inspection device not only improves the quality inspection efficiency of the card production line but also reduces labor costs and error rates, greatly facilitating production and management.

[0024] Preferably, the base frame 40 includes two longitudinal plates 41 arranged in parallel in the transverse direction H and a plurality of crossbars 42 connecting the two longitudinal plates 41. The longitudinal plates 41 have a wedge-shaped structure, which is formed by cutting out a triangular structure from a rectangular plate, thereby forming a slope 43 at the cut-out portion of the two longitudinal plates 41 for mounting the aforementioned conveying unit 30.

[0025] In one example of the present invention, such as Figure 4 , Figure 6 and Figure 7 As shown, the hopper section 10 includes: A support 11 is arranged along the transverse direction H of the base frame 40 and connected to the base frame 40; for example, the support 11 includes a support plate 111 and a connecting rod 112, wherein the support plate 111 is fixedly connected to both sides of the base frame 40, and the connecting rod 112 is fixedly connected to the support plates 111 on both sides to form a support 11 at the upper end of the base frame 40.

[0026] A baffle 12 is connected to the bracket 11 and configured to stop the card 200 to be tested. Specifically, the baffle 12 is fixedly connected to the bracket 11 near the middle position. For example, the baffle 12 is fixedly connected to the center position of the connecting rod 112, so that the card 200 to be tested can always be in the middle position of the hopper section 10, which facilitates the conveying of the card 200 to be tested.

[0027] The first side plate 13 and the second side plate 14 are respectively disposed on both sides of the baffle 12 and connected to the bracket 11 to form a storage cavity A, which is used to limit the degrees of freedom on both sides of the card to be tested 200. An adjustment component 15 is connected to the bracket 11 and to the first side plate 13 and the second side plate 14. Under the action of the adjustment component 15, at least one of the first side plate 13 and the second side plate 14 moves closer to or further away from the other.

[0028] Specifically, based on the width of the card to be tested 200, the distance between the two side plates is adjusted by the adjusting component 15 so that the spacing between the two side plates can be adapted to the card to be tested 200, thereby placing the card to be tested 200 in the storage cavity A defined by the two side plates and the baffle 12, thus preventing the position of the card to be tested 200 from being deflected and affecting its subsequent position on the conveying unit 30.

[0029] In one example of the present invention, such as Figure 8 As shown, the adjustment assembly 15 includes a first screw 151, a second screw 152, and a knob 153, wherein the knob 153 is fixedly connected to the first screw 151 and the second screw 152; A first threaded hole 131 is provided on the first side plate 13, and the first screw 151 is engaged with the first threaded hole 131. A second threaded hole 141 is provided on the second side plate 14, and the second screw 152 is engaged with the second threaded hole 141. The first threaded hole 131 and the second threaded hole 141 have opposite thread directions, and the first screw 151 and the second screw 152 have opposite thread directions.

[0030] Specifically, the adjusting assembly 15 includes a first screw 151 and a second screw 152. A first threaded hole 131 is provided at one end of the first side plate 13 near the second side plate 14. One end of the first screw 151 engages with the first threaded hole 131, and when the first screw 151 rotates within the first threaded hole 131, it can move relative to the first side plate 13. A schematic diagram of the engagement between the first screw 151 and the first threaded hole 131 is shown below. Figure 8 As shown; similarly, a second threaded hole 141 is provided at one end of the second side plate 14 near the first side. One end of the second screw 152 is engaged with the second threaded hole 141, and when the second screw 152 rotates within the second threaded hole 141, the second screw 152 can move relative to the second side plate 14. The schematic diagram of the engagement between the second screw 152 and the second threaded hole 141 is shown below. Figure 8 Similarly, but the second threaded hole 141 has the opposite thread direction to the first threaded hole 131, and the second screw 152 has the opposite thread direction to the first screw 151.

[0031] Meanwhile, the adjustment assembly 15 also includes a knob 153, which is fixedly connected to the first screw 151 and the second screw 152, or the first screw 151 and the second screw 152 are an integral structure, and the knob 153 is fixedly connected to both of them.

[0032] When the knob 153 is rotated, it can drive the first screw 151 and the second screw 152 to rotate. During the rotation, they respectively engage with the first threaded hole 131 and the second threaded hole 141, so that the first screw 151 moves axially relative to the first side plate 13 and the second screw 152 moves axially relative to the second side plate 14, thereby causing the first side plate 13 and the second side plate 14 to move closer to each other or further away from each other.

[0033] Understandably, the connecting rod 112 on the bracket 11 passes through the first side plate 13 and the second side plate 14, and is parallel to the first screw 151 and the second screw 152. The first side plate 13 has a first guide hole, and the second side plate 14 has a second guide hole. The first side plate 13 and the second side plate 14 can move on the connecting rod 112. When the knob 153 is rotated to make the first side plate 13 and the second side plate 14 move relative to each other, the connecting rod 112 can play a guiding role, improving the accuracy of their movement. At the same time, it can also make the first side plate 13 and the second side plate 14 move closer or further apart along the axis of the connecting rod 112, preventing the first side plate 13 and the second side plate 14 from twisting relative to each other.

[0034] In one example of the present invention, such as Figure 9 As shown, In the first side plate 13 and the adjustment assembly 15, one is provided with a first slide rail 132, and the other is provided with a first sliding rod 154, the first sliding rod 154 moving along the first slide rail 132; In the second side plate 14 and the adjustment assembly 15, one is provided with a second slide rail 142, and the other is provided with a second sliding rod 155, which moves along the second slide rail 142; The adjustment assembly 15 further includes a first limiting component 156 and a second limiting component 157. The first limiting component 156 is used to limit the relative movement between the first sliding rod 154 and the first slide rail 132, and the second limiting component 157 is used to limit the relative movement between the second sliding rod 155 and the second slide rail 142.

[0035] In the hopper section 10, the operator can adjust the distance between the first rod and the second rod by controlling the relative movement between the first sliding rod 154 and the first slide rail 132 and the relative movement between the second sliding rod 155 and the second slide rail 142, so that the first side plate 13 and the second side plate 14 can switch between the unfolded position and the retracted position. When the distance between the first rod and the second rod is adjusted to the correct position, the first limiting component 156 and the second limiting component 157 can fix the two in that position.

[0036] The positions of the first side plate 13 and the second side plate 14 can be adjusted respectively by adjusting the adjustment component 15, thereby allowing for more flexible adjustment of the span of the storage cavity in the lateral direction H.

[0037] In one example of the present invention, such as Figure 9 As shown, The first sliding rod 154 is provided with a first protrusion 1561, and the first slide rail 132 is provided with a plurality of first recesses 1562. The first protrusion 1561 is engaged with any of the first recesses 1562. The first limiting member 156 includes the first protrusion 1561 and the first recesses 1562. The second sliding rod 155 is provided with a second protrusion 1571, and the second slide rail 142 is provided with a plurality of second recesses 1572. The second protrusion 1571 is engaged with any of the second recesses 1572. The second limiting member 157 includes the second protrusion 1571 and the second recesses 1572.

[0038] Preferably, the first slide rail 132 is provided with a first spring piece inside, and the first spring piece is bent to form the first recess 1562; the second slide rail 142 is provided with a second spring piece inside, and the second spring piece is bent to form the second recess 1572.

[0039] Specifically, the first slide rail 132 has a first spring sheet inside, which is made of elastic material and is bent to form a plurality of the aforementioned first recesses 1562; similarly, the second slide rail 142 has a second spring sheet inside, which is made of elastic material and is bent to form the aforementioned second recesses 1572. Specifically, the first recesses 1562 can be formed by stamping the first spring sheet and the second recesses 1572 can be formed by stamping the second spring sheet.

[0040] In one example of the present invention, The first slide rail 132 is provided with a first spring piece inside, and the first spring piece is bent to form the first recess 1562; The second slide rail 142 is provided with a second spring piece inside, and the second spring piece is bent to form the second recess 1572.

[0041] In an embodiment of the present invention, when each of the first recesses 1562 and the second recesses 1572 is formed by a spring sheet, the spring sheet can be elastically deformed when subjected to force. Taking the first spring sheet and the first protrusion 1561 as an example, when the first sliding rod 154 slides in the first slide rail 132, the first protrusion 1561 moves along the surface of the first spring sheet and applies pressure to the first spring sheet. Under the action of this pressure, the first spring sheet is elastically deformed, so that the first protrusion 1561 can move with the first sliding rod 154.

[0042] Therefore, when the spring sheet is installed in the first slide rail 132 and the second slide rail 142, it can ensure that the sliding rod and the slide rail can move relative to each other, and can also limit their movement, and has the advantage of simple structure.

[0043] Furthermore, both the first protrusion 1561 and the second protrusion 1571 can be made of elastic material. When the sliding rod moves along the slide rail, both the protrusion and the spring can be elastically deformed, thereby reducing the resistance during the movement of the sliding rod and improving the reliability of the engagement between the protrusion and the recess.

[0044] The outer contours of the first protrusion 1561 and the second protrusion 1571 are both arc-shaped. Correspondingly, the outer contours of the first recess 1562 and the second recess 1572 are also arc-shaped, so that the protrusions and the spring sheet have a smooth transition, thereby further reducing the resistance during the relative movement of the sliding rod and the slide rail, and reducing the wear of the protrusions and the spring sheet, thus improving the service life.

[0045] In one example of the present invention, such as Figure 5 As shown, the drive unit 20 includes: a guide plate 21 and a conveyor belt assembly 22. The guide plate 21 is connected to the bracket 11 and is located at the upper end of the conveyor belt assembly 22; A clamping cavity 23 is formed between the conveyor belt assembly 22 and the guide plate 21. Under the driving action of the conveyor belt assembly 22, the cards to be tested 200 enter the clamping cavity 23 one by one under the guidance of the guide plate 21. The span D of the clamping cavity 23 is the same as the thickness of the card to be tested 200.

[0046] Specifically, such as Figure 10 and Figure 11As shown, when the card to be tested 200 needs to be transported from the storage section to the conveying section 30, the conveyor belt assembly 22 transports the card to be tested 200 located on it. Under the action of friction, the card to be tested 200 at the bottom of the stacked cards to be tested 200 in the storage cavity A is driven first by the conveyor belt assembly 22, while the card to be tested 200 located above it is stopped by the straight plate 211 of the guide plate 21 and the baffle 12. The card to be tested 200 is driven by the conveyor belt assembly 22 and guided by the guide plate 21 into the clamping cavity 23, and finally enters the conveying section 30. Then the next card to be tested 200 at the bottom repeats the above action and enters the clamping cavity 23 in sequence.

[0047] For example, the conveyor belt assembly 22 includes a conveyor motor 221, a conveyor shaft 222, a conveyor wheel 223, and a conveyor belt 224. The conveyor shaft 222 includes two shafts, which are connected parallel to each other on the base frame 40 in the transverse direction H. Each conveyor shaft 222 is fixedly connected to a conveyor wheel 223. Preferably, the conveyor wheel 223 can be positioned near the middle of the conveyor shaft 222. The conveyor belt 224 is sleeved on the two conveyor wheels 223. The conveyor motor 221 is connected to one of the two conveyor shafts 222, so that the conveyor motor 221 drives the conveyor shaft 222 to rotate, and the conveyor shaft 222 drives the conveyor wheel 223 to rotate, which in turn drives the conveyor belt 224 to rotate on the two conveyor wheels 223, and finally realizes that the conveyor belt 224 conveys the card to be tested 200.

[0048] It is understandable that since there is only one valid information side (the side for detecting appearance and RFID code) of the card to be tested 200, when stacking the cards to be tested 200, the valid information side needs to be set at the top so that the valid information side can be set at the top no matter which testing part the card to be tested 200 is transferred to.

[0049] In one example of the present invention, such as Figure 5 The guide plate 21 shown includes a straight plate portion 211 and an arc-shaped portion 212 connected thereto. The straight plate portion 211 is used to stop the cards 200 to be tested stacked on the conveyor belt assembly 22. The arc-shaped portion 212 is disposed opposite to the conveyor belt assembly 22, and its bending direction is consistent with the transmission direction of the conveyor belt assembly 22. It is configured to guide the cards 200 to be tested into the clamping cavity 23 one by one.

[0050] In other words, under the conveying action of the conveyor belt assembly 22, friction is generated between the conveyor belt 224 and the upright test card 200. Since the lower end of the guide plate 21 is an arc-shaped part 212, it is more convenient for the bottom one of the stacked test cards 200 to enter the clamping cavity 23 by the conveyor belt assembly 22.

[0051] In one example of the present invention, such as Figure 5 As shown, the drive unit 20 further includes a support wheel 24, which is connected to the base frame 40 and disposed on one side of the guide plate 21, and the outer contour arc of the support wheel 24 is consistent with the arc of the arc-shaped part 212. Specifically, it also includes: a support rod 25, which is fixed to the base frame 40 along the transverse direction H; a support wheel 24 is fixedly connected to the support rod 25, and the support wheel 24 is in contact with the arc-shaped portion 212 of the guide plate 21. So when the conveyor belt assembly 22 conveys the card to be tested 200, and the card to be tested 200 abuts against the arc-shaped portion 212, the support wheel 24 provides support for the arc-shaped portion 212, making the conveyor belt assembly 22 more stable and reliable when conveying the card to be tested 200.

[0052] In one example of the present invention, such as Figure 6 As shown, the conveying unit 30 includes two guide wheel assemblies 31 arranged in parallel on the base frame 40, and a conveying cavity 33 for conveying the card to be tested 200 is formed between the two guide wheel assemblies 31. It can be understood that the two parallel guide wheel assemblies 31 are installed on the slope 43 and located at the rear end of the clamping cavity 23, so that the card to be tested 200 enters the conveying cavity 33 immediately after entering the clamping cavity 23.

[0053] The guide wheel assembly 31 includes a drive motor 311, multiple rotating shafts 312, multiple rollers 313, and a belt 314. The drive motor 311 is connected to one of the multiple rotating shafts 312. The rotating shafts 312 are arranged along the transverse direction H and are pivotally connected to the base frame 40. The multiple rotating shafts 312 are arranged along the extension direction of the slope 43 of the base frame 40. Each roller 313 is fixedly connected to a corresponding rotating shaft 312, and the belt 314 is sequentially sleeved on the multiple rollers 313. For example, the rotating shafts 312 are pivotally connected to the longitudinal plate 41 via bearings.

[0054] Specifically, such as Figure 3As shown, the conveying unit 30 further includes a transmission mechanism 32, which includes a drive wheel 321, a first wheel 322, a first rotating gear 323, a second rotating gear 324, an auxiliary wheel 325, a tensioning wheel 326, and a transmission bar 327. The drive wheel 321 is fixed on the output shaft of the drive motor 311. The first wheel 322 and the first rotating gear 323 are fixedly connected to one of the rotating shafts 312 of one of the guide wheel assemblies 31. The second rotating gear 324 is fixedly connected to the rotating shaft 312 at the corresponding position on the other guide wheel assembly 31, and the second rotating gear 324 meshes with the first rotating gear 323. The transmission bar 327 is sleeved on the drive wheel 321 and the first wheel 322. The drive motor 311 drives the drive wheel 321 to rotate, thereby driving the first wheel 322 to rotate, which in turn causes the first wheel 322 to rotate. The rotation of the shaft 312 where 22 is located causes the first rotating gear 323 on it to rotate. The first rotating gear 323 drives the second rotating gear 324 meshing with it to rotate, and the second rotating gear 324 drives the shaft 312 connected to it to rotate. During the rotation of the first rotating gear 323, the multiple rotating shafts 312 of the guide wheel assembly 31 are connected by belts 314 to achieve synchronous rotation, thereby enabling the guide wheel assembly 31 to be driven as a whole. During the rotation of the second rotating gear 324, the multiple rotating shafts 312 of the guide wheel assembly 31 are connected by belts 314 to achieve synchronous rotation, thereby enabling the other guide wheel assembly 31 parallel to the above guide wheel assembly 31 to be driven as a whole. When the conveying cavity 33 formed between the two guide wheel assemblies 31 conveys the card to be tested 200, the guide wheel assemblies 31 located on the upper and lower sides of the card to be tested 200 also have the function of conveying the card to be tested 200.

[0055] Preferably, in order to improve the stability of the transmission, an auxiliary wheel 325 is provided on the rotating shaft 312 and sleeved inside the transmission bar 327, and a tensioning wheel 326 is also provided on the outside of the transmission bar 327, so as to adjust the tension of the transmission bar 327.

[0056] In short, the two guide wheel assemblies 31 are driven by the drive motor 311 through the transmission mechanism 32 to drive the rotating shaft 312 to rotate, thereby driving the roller 313 located on the rotating shaft 312 to rotate. Under the connection of the belt 314, multiple rotating shafts 312 rotate synchronously, and the synchronous rotation of the upper and lower guide wheel assemblies 31 forms the conveying cavity 33 to convey the card 200 to be tested.

[0057] It is understandable that the driving direction of the two guide wheel assemblies 31 is consistent with the conveying direction of the conveying cavity 33. For example, the guide wheel assembly 31 located at the lower end rotates counterclockwise, while the guide wheel assembly 31 located at the upper end rotates clockwise, thereby ensuring that the card to be tested 200 entering the conveying cavity 33 can move in the conveying cavity 33.

[0058] Preferably, the gap distance of the conveying cavity 33 formed between the two guide wheel assemblies 31 is the same as the thickness of the card to be tested 200. That is, the gap between the conveying cavity 33 and the clamping cavity is the same, so that the card to be tested 200 entering the conveying cavity 33 can always keep in contact with the belt 314 of the guide wheel assembly 31, thereby facilitating the movement of the card to be tested 200. It is worth noting that, since the upper and lower sides of the conveying cavity 33 are both guide wheel assemblies 31, the card to be tested 200 can be conveyed as long as at least one of the two guide wheel assemblies 31 is working. Therefore, the gap distance of the conveying cavity 33 can be greater than the thickness of the card to be tested 200.

[0059] Generally, different cards 200 to be tested may have different sizes, but the thickness of the substrate will be consistent. However, considering that the thickness may also vary, the card issuing mechanism of the present invention has been further improved and optimized on the original basis.

[0060] In one example of the present invention, the support 11 and the longitudinal plate 41 are connected at an adjustable height, so that the span of the clamping cavity between the guide plate 21 and the conveyor belt assembly 22 is adjustable, thereby enabling the clamping cavity to accommodate cards 200 of different thicknesses to be tested. For example, one of the support plate 111 and the longitudinal plate 41 has an elongated hole, and the other has a positioning hole. Bolts are passed through the elongated hole and the positioning hole in sequence to fix the relative positions of the support plate 111 and the longitudinal plate 41. Specifically, the structure of the elongated hole is formed by selecting two points on the same straight line on a circle or selecting the two ends of the circle that are symmetrical about the circle, and stretching the circle along the straight line or the arc. Designing it as an elongated hole allows the positioning hole to be moved to any position of the elongated hole for fixing, which greatly increases the range of relative movement between the support plate 111 and the longitudinal plate 41.

[0061] It is understandable that when it is necessary to adjust the spacing of the conveying cavities 33 formed between the guide wheel assemblies 31, one of the two guide wheel assemblies 31 can be fixed in one position, and the other can be adjusted using the connection method described above. For example, the guide wheel assembly 31 located at the upper end can be designed as an adjustable structure, with an elongated hole opened on the longitudinal plate 41, and the crossbar 42 fixedly connected to any position in the elongated hole by fasteners, thereby adjusting the spacing of the conveying cavities 33 formed by the guide wheel assemblies 31. It should be noted that in this embodiment, the connection method of the rotating shaft 312, roller 313 and longitudinal plate 41 in the guide wheel assembly 31 is adjusted. At this time, the roller is rotatably connected to the rotating shaft 312 through bearings, and the rotating shaft 312 is connected to the elongated hole on the longitudinal plate 41 by fasteners.

[0062] Preferably, the conveyor mechanism 200 is a belt conveyor, and its structure is similar to that of the conveyor belt assembly 22, which will not be described in detail here.

[0063] In one example of the present invention, the detection mechanism 300 includes: a vision module, an image processing module, a pattern recognition module, and an automated control module, wherein, The vision module is configured to capture card images using a high-precision camera, enabling comprehensive scanning and recognition of the card surface; this technology can simulate the human visual system to efficiently process and analyze images.

[0064] The image processing module is configured to perform a complex image processing workflow on captured images, including image enhancement, filtering and denoising, and edge detection, to improve image quality and highlight key features. This process helps to more accurately identify defects or anomalies on the cards later.

[0065] The pattern recognition module is configured to perform depth analysis of card images using pattern recognition algorithms, building upon image processing. These algorithms can identify elements such as text, patterns, and barcodes on the card and determine whether they conform to preset standards and specifications. Any discrepancies are identified as quality issues.

[0066] The automated control module is configured to trigger different electrical control actions based on card image pattern recognition. This determines whether an object is qualified, causing it to fall into either a "qualified" or "unqualified" conveyor path, thus achieving automatic continuous quality inspection. Unqualified products are automatically rejected. For example, a rejection mechanism, such as a pneumatic pusher, is used to remove unqualified products. When the rejection mechanism detects a non-qualified card, the pneumatic pusher extends to remove the card 200 into a non-qualified container. The pusher then retracts to its initial position. When the next non-qualified instruction is issued, the rejection mechanism repeats this process. It is understood that the rejection mechanism is located at the rear end of the conveyor line mechanism 200, behind the component that detects non-qualified products.

[0067] It is worth noting that the aforementioned testing agency 300 uses existing and mature technology, which will not be elaborated on here.

[0068] According to a second aspect of the present invention, a detection method for the card detection device 1000 described above includes the following steps: The cards 200 to be tested are stacked in the hopper section 10. The drive section 20 drives the cards 200 to be tested in the hopper section 10 to the conveyor section 30. During this process, under the driving action of the conveyor belt assembly 22, the cards 200 to be tested stacked in the hopper section 10 are guided by the guide plate 21 and enter the clamping cavity 23 one by one from the bottom up. Then the conveyor section 30 conveys the cards 200 to be tested to the conveyor line mechanism 200. The inspection agency 300 inspects the appearance and RFID code of the card to be inspected on the conveyor line mechanism 200 to determine whether it is qualified. If the card to be inspected is unqualified, it is rejected. The qualified card to be inspected flows into the turnover box.

[0069] This card inspection method utilizes a card-issuing mechanism to sequentially distribute cards onto a conveyor line, followed by rapid sorting and rejection by an inspection mechanism. This achieves efficient and accurate card quality inspection. The card-issuing mechanism of this invention has a simple structure, can adapt to issuing cards of different sizes, and only requires the cards to be stacked flat initially for efficient sequential distribution, greatly improving issuance efficiency and saving manpower and resources. The clamping and conveying cavities used in this mechanism effectively prevent cards from flipping during transport, thus preventing subsequent inspection mechanisms from failing to identify the cards and causing mis-detection. This card inspection device not only improves the quality inspection efficiency of the card production line but also reduces labor costs and error rates, bringing great convenience to production and management.

[0070] The foregoing has described in detail, with reference to preferred embodiments, exemplary implementations of the card detection device 1000 and its detection method proposed in this invention. However, those skilled in the art will understand that various modifications and alterations can be made to the above specific embodiments without departing from the concept of this invention, and various combinations can be made to the various technical features and structures proposed in this invention without exceeding the protection scope of this invention, which is determined by the appended claims.
