Description

Technical Field

[0001] The present invention relates to the technical field of access control card detection, in particular to a detection device applied to access control cards. Background Art

[0002] Access card is an identity verification device.

It is widely used in real life. In the production process of access card, it is usually necessary to print corresponding graphic information according to customer needs. In order to ensure the production quality of access card, it is necessary to inspect the access card through a visual inspection device; Existing access control card detection devices, such as the fault detection device for access control cards with publication number CN116720534B, include a frame, a conveyor belt, a code reader, a code reader detection component, an access control card pushing component, and a pushing detection component, wherein: the conveyor belt is arranged on the first side of the frame; the code reader is arranged on the first side of the conveyor belt, and is used to read the access control card to be detected conveyed by the conveyor belt; the code reader detection component is arranged on the third side of the code reader, and is used to perform status detection on the code reader; the access control card pushing component is arranged on the fifth side of the code reader detection component, and is used to push abnormal access control cards off the conveyor belt; the pushing detection component is arranged on the sixth side of the access control card pushing component, and is connected to the code reader detection component through a transmission member, and after the access control card pushing component has pushed the target number of times continuously, the code reader detection component detects the code reader. This implementation achieves effective detection of access control cards; In actual use, although the above-mentioned existing access control card detection device can realize the detection function of the access control card, it cannot realize the flipping function of the access control card, which results in the inability to synchronously detect both sides of the access control card during the detection process, thereby resulting in low detection efficiency. Therefore, in view of the above-mentioned problem, a detection device applied to the access control card is designed to better meet the actual use needs. Summary of the invention

Through the functions of the first material receiving box and the second material receiving box, qualified access control card bodies and defective access control card bodies can be classified and collected, and with the function of the access control card reader, it can be detected whether the access control card body can be used normally.

[0006] Preferably, the unloading mechanism includes a storage box, a convex strip, a movable rod, a rotating rod, a guide rod, a first spring and a rubber ball. The storage box is fixed on the mounting table, and the access control card body is placed in the storage box. The storage box and the push plate are slidably connected, and convex strips are fixed at equal intervals on the left side of the storage box. Through the above structure, a basic guarantee can be provided for the intermittent unloading of the access control card body.

[0007] Preferably, a movable rod is slidably connected to the left side of the storage box, and the movable rod is rotatably connected to one end of the rotating rod, and the other end of the rotating rod is rotatably connected to the fixed plate.

[0008] Preferably, the movable rod is slidably connected to the guide rod, and a first spring is fixed between the guide rod and the movable rod, and a rubber ball is fixed on the guide rod. When the movable rod drives the rubber ball to move up and down, the elastic action of the first spring and the sliding action between the rubber ball and the convex strip enable the rubber ball to knock on the storage box, thereby ensuring the normal unloading of the access control card body.

[0009] Preferably, the detection mechanism includes a support rod, a mounting plate and an industrial camera, the support rod is fixed on the mounting platform, and the mounting plate is fixed on the support rod, and the industrial camera is symmetrically fixed on the lower end surface of the mounting plate.

The second cylinder is fixed on the mounting table, and a blanking plate is fixed to the output end of the second cylinder, and a camera is fixed to the left side of the blanking plate. At the same time, a ramp block is fixed on the blanking plate. The height of the ramp block is greater than the thickness of the access control card body. The position of defective products of the access control card body can be detected by the camera. Through the action of the second cylinder and the blanking plate, the defective products of the access control card body can be sent to the second receiving box for collection for subsequent processing.

[0012] Preferably, the fixing frame is fixed on the mounting table, and a bracket is fixed on the fixing frame, and a vertical rod is slidably connected to the bracket, and a second spring is fixed between the vertical rod and the bracket.

[0013] Preferably, a baffle is fixed to the lower end of the vertical rod, and the distance between the lower end surface of the baffle and the upper end surface of the conveyor belt is equal to the height of the inclined block. A connecting rod is fixed on the vertical rod, and the connecting rod and the inclined block are slidably connected. Through the action of the baffle, the defective access control card body can be shielded to prevent the defective access control card body from mixing into the qualified access control card body, thereby effectively ensuring the production quality.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The detection device applied to the access card adopts a flipping mechanism and a linked feeding mechanism, which can not only realize the flipping of the access card body to ensure the double-sided detection of the access card body, but also realize the automatic loading and unloading of the access card body in the flipping mechanism to ensure the normal operation of the device. Specifically, the first cylinder extends to drive the fixed plate and the push plate to move, so that the access card body can be sent into the left card slot of the flip frame to realize the detection of one side of the access card body. When the first cylinder contracts to drive the fixed plate and the push plate to reset, the friction plate and the friction wheel are cooperated to make the flip frame rotate 180° to realize the detection of the other side of the access card body. When the first cylinder extends again to drive the fixed plate and the push plate to load, the access card body cooperates with the card slot, so that the top plate and the slide bar can be forced to move, so that the right access card body is automatically separated from the card slot, thereby realizing the automatic loading and unloading of the access card body in the flipping mechanism. 2. The detection device applied to the access card adopts a linked knocking mechanism, which can ensure the smooth unloading of the access card body and avoid the access card body from sliding in the storage box. Specifically, when the first cylinder drives the fixed plate and the push plate to move, the movable rod and the rubber ball can be moved in cooperation with the transmission effect of the rotating rod. In cooperation with the sliding effect between the rubber ball and the convex strip and the elastic effect of the first spring, the rubber ball can knock on the storage box, causing the storage box to produce a slight vibration, thereby ensuring the normal falling of the access card body in the storage box; 3. The detection device applied to the access control card adopts a pushing mechanism with a blocking structure, which can send the defective access control card body into the second receiving box for collection, so as to avoid the defective access control card body being mixed with the qualified access control card body. Specifically, when the camera detects the defective access control card body, the defective card body can be pushed into the second receiving box for collection through the second cylinder and the unloading plate, and the baffle moves down and contacts with the conveyor belt with the action of the inclined block, the connecting rod and the second spring, so as to shield the defective access control card body and avoid the defective access control card body being mixed into the first receiving box under the conveyance of the conveyor belt, causing confusion between the defective access control card body and the qualified access control card body.

[0018] See also Figure 1-Figure 6 The present invention provides a technical solution: a detection device for access control cards, comprising a mounting platform 1 and a conveyor belt 2, wherein the conveyor belt 2 is fixed on the right side of the mounting platform 1, and the upper end surface of the conveyor belt 2 is flush with the upper end surface of the mounting platform 1, a first cylinder 3 is fixed on the left side of the upper end surface of the mounting platform 1, a fixed plate 4 is fixed on the output end of the first cylinder 3, a push plate 5 is fixed on the right end of the fixed plate 4, a feeding mechanism 6 is fixed on the mounting platform 1, a detection mechanism 8 is arranged on the right side of the mounting platform 1, and a flipping mechanism 9 is connected to the mounting platform 1, and the flipping mechanism 9 comprises a flipping frame 901, a friction wheel 902, a friction plate 903, and a card slot 9 04, rubber pad 905, slide bar 906 and top plate 907, the flip frame 901 is connected to the mounting platform 1 through a one-way bearing, a friction wheel 902 is fixed on the flip frame 901, the friction wheel 902 is in contact with the friction plate 903, the friction plate 903 is fixed to the fixed plate 4, two card slots 904 are fixed on the flip frame 901, rubber pads 905 are fixed in the card slots 904, the rubber pads 905 are in contact with the access card body 7 to achieve position limiting, a slide bar 906 is slidably connected in the flip frame 901, a top plate 907 is symmetrically fixed on the slide bar 906, and a pushing mechanism 10 is installed on the mounting platform 1.

[0019] A first material receiving box 101 is arranged at the right end of the mounting platform 1, and a second material receiving box 102 is arranged at the rear side of the mounting platform 1, and an access control card reader 103 is installed on the mounting platform 1; the unloading mechanism 6 includes a storage box 601, a convex strip 602, a movable rod 603, a rotating rod 604, a guide rod 605, a first spring 606 and a rubber ball 607, the storage box 601 is fixed on the mounting platform 1, and an access control card body 7 is placed in the storage box 601, and the storage box 601 and the access control card body 7 are connected. The push plates 5 are slidably connected, and convex strips 602 are fixed at equal intervals on the left side of the storage box 601; the detection mechanism 8 includes a support rod 801, a mounting plate 802 and an industrial camera 803, the support rod 801 is fixed on the mounting platform 1, and the mounting plate 802 is fixed on the support rod 801, and the industrial camera 803 is fixed symmetrically on the lower end surface of the mounting plate 802; the flip frame 901 can only rotate clockwise, and the flip frame 901 rotates 180° each time; When using the detection device for access control cards, Figure 1-Figure 5 As shown, first put the access card body 7 to be tested into the storage box 601, at this time, the first cylinder 3 is in a retracted state, and the lowermost access card body 7 is in contact with the upper end surface of the mounting platform 1 and the right end surface of the push plate 5. When loading, the first cylinder 3 extends to drive the fixing plate 4 and the push plate 5 to move to the right, and the push plate 5 pushes the lowermost access card body 7 to move to the right. At this time, the push plate 5 blocks the lower opening of the storage box 601 until the access card body 7 is nested with the left card slot 904 of the flip frame 901, and the friction between the rubber pad 905 and the access card body 7 can ensure the stability of the access card body 7. When the access card body 7 is nested with the card slot 904, the access card body 7 exerts a force on the left top plate 907 on the flip frame 901, causing the top plate 907 and the slide bar 906 to move to the right. After the card body 7 and the left card slot 904 of the flip frame 901 are nested, the access card body 7 is located above the access card reader 103. The access card reader 103 can detect whether the access card body 7 can be used normally, and the left industrial camera 803 is used to detect the graphics printed on the front of the access card body 7. When the fixed plate 4 moves to the right, the friction plate 903 is synchronously driven to move to the right. At this time, due to the limitation of the one-way bearing, the flip frame 901 will not rotate. When the access card body 7 is detected by the left industrial camera 803, the first cylinder 3 contracts and drives the fixed plate 4 and the push plate 5 to move to the left and reset, and synchronously drives the friction plate 903 to move to the left, and cooperates with the friction between the friction plate 903 and the friction wheel 902 to make the flip frame 901 rotate 180° clockwise, thereby realizing the flipping of the access card body 7. Figure 4As shown, at this time, part of the access card body 7 is in contact with the conveyor belt 2. Due to the friction between the rubber pad 905 and the access card body 7, the conveyor belt 2 cannot convey the access card body 7 to the right. In conjunction with the right industrial camera 803, the graphics printed on the back of the access card body 7 can be detected. After the fixing plate 4 and the pushing plate 5 are reset, the blocking effect on the lower opening of the storage box 601 is released, so that the access card body 7 in the storage box 601 can fall normally. By extending the first cylinder 3 again, the loading effect of the second access card body 7 can be realized, so that the second access card body 7 and the card slot 904 are nested and matched. In the nesting of the second access card body 7 and the card slot 904, the top plate 907 can be forced to move to the right, so that the right top plate 907 pushes the first access card body 7 outward, so that the first access card body 7 is separated from the card slot 904 and falls onto the conveyor belt 2. Figure 5 As shown, the first access card body 7 that has been inspected can be conveyed to the right by the conveyor belt 2, thereby realizing the automatic flipping double-sided inspection and automatic loading and unloading of the access card body 7; The left side of the material storage box 601 is slidably connected with a movable rod 603, and the movable rod 603 is rotatably connected to one end of a rotating rod 604, and the other end of the rotating rod 604 is rotatably connected to the fixed plate 4; the movable rod 603 is slidably connected to a guide rod 605, and a first spring 606 is fixed between the guide rod 605 and the movable rod 603, and a rubber ball 607 is fixed to the guide rod 605; When the first cylinder 3 drives the fixed plate 4 and the push plate 5 to move to realize the intermittent feeding of the access card body 7, Figure 1-Figure 3 As shown, when the fixed plate 4 moves to the right, the transmission action of the rotating rod 604 is cooperated, so that the movable rod 603 is forced to move up, and when the fixed plate 4 moves to the left, the transmission action of the rotating rod 604 is cooperated, so that the movable rod 603 is forced to move down, so that the movable rod 603 can move up and down in an orderly manner. When the movable rod 603 moves, the rubber ball 607 is synchronously driven to move. When the rubber ball 607 contacts and slides with the convex strip 602, the rubber ball 607 is separated from the storage box 601. When the rubber ball 607 is separated from the convex strip 602, under the elastic action of the first spring 606, the rubber ball 607 is reset and contacts the storage box 601 for knocking. Through the knocking action of the rubber ball 607, the storage box 601 is slightly shaken, so that the access card body 7 in the storage box 601 can be smoothly dropped, and the access card body 7 is prevented from being stuck in the storage box 601 and affecting the normal unloading. The pushing mechanism 10 includes a second cylinder 1001, a blanking plate 1002, a camera 1003, an inclined block 1004, a fixing frame 1005, a bracket 1006, a vertical rod 1007, a second spring 1008, a baffle 1009 and a connecting rod 1010. The second cylinder 1001 is fixed on the mounting platform 1, and the output end of the second cylinder 1001 is fixed with a blanking plate 1002, and the camera 1003 is fixed on the left side of the blanking plate 1002. At the same time, an inclined block 1004 is fixed on the blanking plate 1002, and the height of the inclined block 1004 is greater than the height of the access card. The thickness of the body 7; the fixed frame 1005 is fixed on the mounting table 1, and the fixed frame 1005 is fixed with a bracket 1006, and the bracket 1006 is slidably connected with a vertical rod 1007, and a second spring 1008 is fixed between the vertical rod 1007 and the bracket 1006; a baffle 1009 is fixed to the lower end of the vertical rod 1007, and the distance between the lower end surface of the baffle 1009 and the upper end surface of the conveyor belt 2 is equal to the height of the inclined plane block 1004, and a connecting rod 1010 is fixed on the vertical rod 1007, and the connecting rod 1010 is slidably connected to the inclined plane block 1004; During the operation of the device, Figure 1-Figure 6As shown, when the access card reader 103 detects that the access card body 7 can be used normally, and the two industrial cameras 803 detect that the images and texts printed on the front and back of the access card body 7 are qualified, it indicates that the access card body 7 is a qualified product. At this time, the qualified products can be conveyed to the first receiving box 101 for collection through the conveyor belt 2. On the contrary, when there is a problem in one of the detections, it indicates that the access card body 7 is a defective product. When it is detected that the access card body 7 is a defective product, when the defective access card body 7 falls on the conveyor belt 2 and moves from left to right, when the defective access card body 7 is detected by the camera 1003, the second cylinder 1001 extends to drive the blanking plate 1002, the camera 1003 and the inclined block 1004 to move backward, and the conveyor belt 2 continues to drive the defective access card body 7 to move to the right. During the movement of the inclined block 1004, when the inclined block 1004 is separated from the connecting rod 1010, at this time, the second spring 1008 Under the action of the conveyor belt 2, the vertical rod 1007 and the baffle 1009 move downward until the baffle 1009 contacts the conveyor belt 2, thereby blocking the defective access card body 7 to prevent the defective access card body 7 from being mixed into the first receiving box 101 under the conveying action of the conveyor belt 2. When the lower plate 1002 moves backward and contacts the defective access card body 7, the defective access card body 7 is forced to move backward until the defective access card body 7 falls into the second receiving box 102. After the defective access control card body 7 is collected and falls into the second receiving box 102, the second cylinder 1001 contracts to drive the blanking plate 1002, the camera 1003 and the inclined block 1004 to reset, and the inclined block 1004 and the connecting rod 1010 are in contact and sliding action, so that the vertical rod 1007 and the baffle 1009 move up and reset. At this time, the second spring 1008 is stressed and is in a contracted state for next use. This is the working principle of the detection device applied to the access control card.
