Description

Technical Field

[0001] This utility model relates to the field of file box technology, specifically to a file box label recognition device that can be quickly located. Background Technology

[0002] With the development of information technology, the digitization of archival management has become an inevitable trend. Among the key steps in achieving rapid inventory, retrieval, and location of archives is the electronic labeling of physical archive boxes (such as affixing barcodes, QR codes, or RFID tags) and the collection of information through identification devices. Currently, the most common methods for identifying archive box tags are handheld scanning and fixed scanning. Handheld scanning relies on manual operation, which is inefficient and prone to errors. Fixed scanning requires placing the archive box into a specific identification device, where a built-in scanner or camera automatically completes the identification. However, existing fixed identification devices have significant structural defects, severely affecting their identification efficiency and reliability.

[0003] Traditional fixed identification devices typically employ a simple cavity structure, relying on the weight of the file box itself to rest at the bottom of the enclosure. Before identification, the lack of an effective positioning mechanism results in random placement of the file box within the enclosure. This leads to significant angular and distance deviations between the label surface of the file box and the camera or scanner, easily causing identification failures or misreadings. Repeated manual adjustments are required, further reducing the efficiency of file box label positioning and identification. Therefore, there is an urgent need in this field for a novel file box label identification device that can quickly and adaptively perform precise and gentle positioning of file boxes of different sizes and slightly tilted shapes, enhancing the stability of the file box during placement and ensuring accurate label identification at all times. Furthermore, it should possess the characteristics of simple structure, high reliability, and low cost. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a file box label recognition device that can quickly locate the label.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A file box label recognition device that can quickly locate files includes:

[0007] Box;

[0008] The label recognition mechanism, located on the inner wall of the box, is used to identify the labels on the file box;

[0009] An electric push rod is located at the top of the inner cavity of the box and has a connecting plate at its telescopic end;

[0010] Two sets of positioning mechanisms are symmetrically arranged on both sides of the inner cavity of the box via a linkage plate, and the label recognition mechanism is located on the vertical plane of the clamping space formed between the two sets of positioning mechanisms. The positioning mechanisms, from top to bottom, include:

[0011] A rotating plate is rotatably located in the upper part of the inner cavity of the box, and the middle of the long edge of the rotating plate is hinged to the connecting plate.

[0012] A flexible plate is movably located in the middle of the inner cavity of the box, and the end of the flexible plate away from the rotating plate has an arc-shaped protrusion.

[0013] The positioning plate is movably located at the bottom of the inner cavity of the box, and the side of the positioning plate facing the clamping space has an arc-shaped concave surface. When clamping the file box, the edge of the file box will slide along the arc-shaped concave surface until the file box is parallel to the length direction of the positioning plate.

[0014] The flexible rod can be bent under force, and the rotating plate and the positioning plate are fixed at both ends of the flexible plate respectively through the flexible rod;

[0015] The flexible plate abuts against the surface of the file box and bends and deforms itself, causing the arc-shaped protrusion of the flexible plate to elastically deform into a plane, forcing the positioning plate to apply a downward force to the file box.

[0016] Preferably, the length of the positioning plate is greater than the length of the flexible plate and the rotating plate, and the two ends of the positioning plate slide against the inner wall of the box.

[0017] Preferably, the positioning plate has multiple sets of reinforcing ribs along its width on the side facing away from the arc-shaped concave surface, and the axial direction of the reinforcing ribs is parallel to the length direction of the positioning plate. At the same time, the cross-sectional area of ​​the reinforcing ribs gradually decreases from the middle to both ends.

[0018] Preferably, the arc-shaped protrusion of the tough plate has multiple sets of closed deformation slots symmetrically opened on the side facing away from the clamping space, and the length direction of the deformation slots is parallel to the axis of the arc-shaped protrusion. At the same time, when the arc-shaped protrusion deforms, the opening of the deformation slots will expand into a V shape.

[0019] Preferably, the toughening rod at the end of the toughening plate near the rotating plate is thicker than the toughening rod at the end of the toughening plate near the positioning plate.

[0020] Preferably, the cross-sectional dimensions of the toughening rod gradually increase from the middle to both ends, and the side of the toughening rod closest to the toughening plate is in the same plane.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] By setting up two sets of symmetrical positioning mechanisms and utilizing the arc-shaped concave surface on the positioning plate, when the file box is placed in, its edges will automatically slide along the arc-shaped concave surface as it is clamped by the positioning plate until the length of the box is parallel to the positioning plate. This process can automatically compensate for the angular deviation that occurs during placement, achieving rapid and accurate centering of the file box in the horizontal plane, greatly reducing the requirements for initial placement accuracy. Furthermore, when the positioning mechanism clamps, the flexible plate will contact the side wall of the file box after the positioning plate and undergo controllable bending deformation, providing a good cushioning effect. It effectively prevents rigid impacts from damaging the file box. Moreover, as the clamping force increases, the arc-shaped protrusion at the end of the flexible plate will elastically deform from an arc to a plane, decomposing and converting the horizontal clamping force on the side of the file box into a vertically downward component force. This component force can press the file box against the placement point inside the box, eliminating the file box's vertical freedom and slight swaying, providing a stable platform for label recognition. Furthermore, through the deformation of the flexible plate, the device can also handle various file boxes within a certain size range without any mechanical adjustment, making it highly versatile.

Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0030] Example

[0031] like Figures 1 to 4 As shown, the file box label recognition device that can quickly locate the file includes:

[0032] Box 1;

[0033] The label recognition mechanism 5 is located on the inner wall of the box 1 and is used to recognize the labels on the file box.

[0034] Electric push rod 2, which is located at the top of the inner cavity of the box 1 and has a connecting plate 21 at the telescopic end;

[0035] Two sets of positioning mechanisms 4 are symmetrically arranged on both sides of the inner cavity of the box 1 via a connecting plate 21, and the label recognition mechanism 5 is located on the vertical plane of the clamping space formed between the two sets of positioning mechanisms 4. The positioning mechanisms 4, from top to bottom, include:

[0036] Rotating plate 41 is rotatably disposed on the upper part of the inner cavity of box 1, and the middle part of the long edge of rotating plate 41 is hinged to connecting plate 21.

[0037] The flexible plate 43 is movably disposed in the middle of the inner cavity of the box 1, and the end of the flexible plate 43 away from the rotating plate 41 is provided with an arc-shaped protrusion 431.

[0038] Positioning plate 44 is movably located at the bottom of the inner cavity of the box 1, and the positioning plate 44 has an arc-shaped concave surface on the side facing the clamping space. When clamping the file box, the edge of the file box will slide along the arc-shaped concave surface until the file box is parallel to the length direction of the positioning plate 44.

[0039] The flexible rod 42 can be bent under force, and the two ends of the flexible plate 43 are respectively fixed to the rotating plate 41 and the positioning plate 44 through the flexible rod 42;

[0040] The flexible plate 43 abuts against the surface of the file box and bends and deforms itself, causing the arc protrusion 431 of the flexible plate 43 to change from an arc surface to a plane, forcing the positioning plate 44 to apply a downward force to the file box.

[0041] Specifically, the file box to be identified is placed on the loading plate 11 inside the box 1 through the insertion opening in the box 1, with the label of the file box facing the label recognition mechanism 5. The switch of the electric push rod 2 is activated, and the telescopic end of the electric push rod 2 pushes the rotating plate 41 to rotate through the linkage plate 21. The rotating plate 41 pushes the positioning plate 44 closer to the file box through the flexible rod 42 and the flexible plate 43. When the two sets of positioning plates 44 abut against the sides of the file box, the edges of the file box will slide along the arc concave surface of the positioning plate 44, so that the file box can be parallel to the positioning plate 44 in the preset position, completing the initial horizontal and vertical dual positioning. Then, the label on the surface of the file box can be aligned with the label recognition mechanism 5. The label recognition mechanism 5 facilitates subsequent recognition. When the arc protrusion 431 of the flexible plate 43 abuts against the surface of the file box, the positioning plate 44 is also parallel to the surface of the file box when it is pressing the surface of the file box. The flexible rod 42 corresponding to the positioning plate 44 is bent into an obtuse angle. As the arc protrusion 431 of the flexible plate 43 is gradually flattened, the flexible plate 43 can apply a downward component force to the positioning plate 44. This component force can be applied to the file box through the positioning plate 44, forcing the file box to press against the preset position on the surface of the carrier plate 11, enhancing the stability of the file box when placed on the surface of the carrier plate 11, thereby improving the stability and accuracy of the device when recognizing the file box label.

[0042] The carrier plate 11 has a through slot in the middle, and a pressure sensor is installed in the through slot. Both the pressure sensor and the electric push rod 2 are electrically connected to the external PLC component. When the file box is placed in the preset position of the carrier plate 11, the file box will apply pressure to the pressure sensor, and the pressure sensor will transmit the pressure data to the PLC component. After receiving the data, the PLC component will automatically start the electric push rod 2, thereby improving the ease of operation and positioning recognition efficiency of the device.

[0043] The length of the positioning plate 44 is greater than the lengths of the flexible plate 43 and the rotating plate 41, and the two ends of the positioning plate 44 slide against the inner wall of the box 1.

[0044] Specifically, the extended positioning plate 44 is designed so that both ends can always maintain sliding contact with the inner wall of the box 1, forming a stable guiding structure. On the one hand, this ensures that the positioning plate 44 will not deflect or tilt during movement, and will always smoothly approach or move away from the file box along the preset path, ensuring the accuracy and repeatability of the clamping action. On the other hand, the extended plate has a larger contact area with the inner wall of the box 1, which effectively disperses the lateral force generated during clamping, improves the rigidity and stability of the entire positioning mechanism 4 during operation, and prevents the mechanism from deforming or shaking due to excessive local stress, thus providing a more stable platform for label recognition.

[0045] The positioning plate 44 has multiple sets of reinforcing ribs 441 arranged along the width direction on the side facing away from the arc-shaped concave surface. The axial direction of the reinforcing ribs 441 is parallel to the length direction of the positioning plate 44, and the cross-sectional area of ​​the reinforcing ribs 441 gradually decreases from the middle to both ends.

[0046] Specifically, a reinforcing rib 441 parallel to the length direction is provided on the back of the positioning plate 44. The core purpose is to significantly enhance its bending stiffness. When the positioning plate 44 receives the thrust from the top through the toughness rod 42 and squeezes the file box, the reinforcing rib 441 can effectively resist the bending deformation of the plate that may be caused by the reaction force of the file box, ensuring that the clamping force is evenly applied to the side of the file box, and avoiding inaccurate positioning or unstable clamping due to plate deformation.

[0047] The arc-shaped protrusion 431 of the resilient plate 43 has multiple sets of closed deformation slots symmetrically opened on the side facing away from the clamping space. The length direction of the deformation slot is parallel to the axis of the arc-shaped protrusion 431. At the same time, when the arc-shaped protrusion 431 deforms, the opening of the deformation slot will expand into a V shape.

[0048] Specifically, the pre-set deformation slots on the back of the arc-shaped protrusion 431 provide a clear "hinge" and guide for its controllable elastic deformation from the arc surface to the plane. These parallel slots divide the continuous arc surface into multiple independent micro-bending "rib" structures, which greatly reduces the force required for the arc surface to be flattened, making its deformation smoother and easier, and avoiding irreversible plastic deformation or fatigue damage. When deformation occurs, the slots expand into a V-shape, precisely releasing the compressive stress on the material surface, ensuring that the tough plate 43 can efficiently convert the horizontal thrust into a downward pressure component, while ensuring the high reversibility of deformation and the long life and high reliability of the mechanism.

[0049] The toughness rod 42 at the end of the toughness plate 43 near the rotating plate 41 is thicker than the toughness rod 42 at the end of the toughness plate 43 near the positioning plate 44.

[0050] Specifically, the upper and lower flexible rods 42 are designed with different thicknesses (i.e., different bending stiffnesses) based on their different roles in the force transmission chain. The upper flexible rod 42, which is closer to the rotating plate 41, is thicker and its primary task is to reliably transmit the main horizontal thrust brought by the connecting plate 21. Its greater stiffness ensures that the thrust can be transmitted downward efficiently and its own bending deformation is small. The lower flexible rod 42, which is closer to the positioning plate 44, is relatively thinner. Its design intention is to allow and control it to undergo the expected bending deformation, thereby converting the horizontal thrust into a component force that pushes the positioning plate 44 down. This differentiated stiffness design realizes the directional decomposition and transmission of force.

[0051] The cross-sectional dimensions of the toughness bar 42 gradually increase from the middle to both ends, and the side of the toughness bar 42 close to the toughness plate 43 is in the same plane.

[0052] Specifically, the toughness bar 42 adopts a gradually changing cross-section design that is thinner in the middle and gradually thickens towards both ends. This allows its bending stiffness to smoothly transition from the middle (where the bending moment is greatest) to both ends (where the bending moment is smaller and a firm connection with the rotating plate 41, toughness plate 43, and positioning plate 44 is required). This avoids stress concentration that may occur at the abrupt change in cross-section, thereby significantly improving the fatigue life and load-bearing capacity of the toughness bar 42 and preventing breakage after repeated bending. At the same time, it ensures that the sides of the toughness bar 42 connected to the toughness plate 43 are on the same plane, guaranteeing smooth force transmission and uniform contact stress distribution at the connection, thus enhancing the overall integrity and motion stability of the entire linkage mechanism.

[0053] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
