Description

Technical Field

[0001] This invention relates to the field of document scanning and sorting equipment, specifically to an automatic scanning, sorting, and sorting device for medical records. Background Technology

[0002] With the continuous improvement of hospital information technology infrastructure, medical institutions have gradually transitioned to full-process information management in areas such as outpatient services, inpatient care, laboratory testing, examinations, imaging, and medical record management. Most newly generated diagnostic and treatment data can be directly stored, retrieved, and archived within the medical information system. However, a large amount of paper-based medical records generated during past medical activities are still stored in the medical records room. To achieve unified management of historical medical records and the existing medical information system, hospitals often need to centrally scan and convert the paper-based data stored in the medical records room into electronic images for subsequent import into the medical system, enabling long-term preservation, rapid retrieval, remote access, and unified archiving. Therefore, continuous, efficient, and automated scanning of a large number of historical medical records is a crucial issue that hospitals need to address during the digitization migration of existing medical records.

[0003] Currently, when digitizing medical records, scanning equipment with automatic paper feeding is typically used. Stacked sheets of paper are fed into the scanning area one by one via friction conveying by paper feed rollers or negative pressure suction from paper separation nozzles. However, hospital medical records often consist of various types of paper, with differences in size, thickness, and paper material between different records and within the same record. Examples include A4 paper, A5 paper, examination reports, lab reports, and various non-standard sized documents. Existing automatic scanning equipment typically designs paper feed rollers or paper separation nozzles for fixed-size or regularly arranged papers. When different sizes of paper are mixed and stacked, especially when the upper layer is smaller, traditional paper separation nozzles, during the process of adsorbing the upper layer, often fail to provide effective separation space between adjacent sheets and cannot effectively align the paper ends. This can easily lead to the simultaneous adsorption or movement of lower-layer papers, resulting in consecutive, duplicate, or even multiple sheets entering the scanning area, affecting scan quality and data integrity. Furthermore, traditional paper feed rollers, due to contact with the lower-layer papers, can easily carry them out as well. To avoid the above problems, staff usually need to manually sort, classify, and separate the medical records page by page before scanning. This not only increases the cost of manual operation but also reduces the efficiency of continuous digitization of large amounts of medical records. Summary of the Invention

[0004] In view of the deficiencies in the prior art, the purpose of this invention is to provide an automatic scanning, classification and sorting device for medical records.

[0005] An automatic scanning, sorting, and classifying device for medical records according to the present invention includes a main housing and a secondary housing arranged opposite to each other. An embedded mounting plate is provided on the lower inner side of the secondary housing. The embedded mounting plate and the secondary housing together form a paper conveying channel. A paper separating mechanism is provided on the main housing and the secondary housing for storing paper and separating papers of different sizes one by one. An ADF scanner for scanning the paper passing through is horizontally arranged on the inner wall of the secondary housing. A detection unit for detecting paper size is provided on the embedded mounting plate and the lower inner wall of the secondary housing. An output archiving mechanism is provided below the main housing and the secondary housing for classifying and storing the scanned paper.

[0006] Preferably, the paper separating mechanism includes: A telescopic component is provided on one side of the bottom of the main housing, and the telescopic component is used to adjust the tilt angle of the entire automatic scanning, sorting and sorting device; The paper storage frame is movably mounted on the support platform inside the main housing. The paper storage frame has an open structure and its lower sidewall is slidably connected to the upper end of the embedded mounting plate. The inner side of the sub-housing is provided with an adsorption element for adsorbing the paper in the paper storage frame through an opening in the mounting groove. The adsorption end of the adsorption element is located on one side of the sub-housing and corresponds to the position where the paper is gathered. An auxiliary separation mechanism is provided on the main housing below the paper storage frame. The auxiliary separation mechanism drives the paper storage frame to vibrate at high frequency and simultaneously peels the adsorbed paper off the paper behind it. A horizontal adjustment element is provided, which is disposed in a mounting groove on the inner wall of the sub-housing to ensure that the peeled paper falls in an attitude parallel to the ADF scanner.

[0007] Preferably, the auxiliary separation mechanism includes a synchronous belt, which is disposed on the inner wall of the main housing below the paper storage frame. A matching accessory is fixedly disposed on the synchronous belt, and a sliding sleeve is rotatably connected to the end of the matching accessory. A page-separating scraper is slidably connected inside the sliding sleeve. The upper end of the page-separating scraper is also slidably connected to a horizontal groove at the top of the embedded mounting plate. The synchronous belt drives the page-separating scraper to reciprocate within the groove of the embedded mounting plate through the matching accessory and the sliding sleeve. Two vibrating wheels are symmetrically rotatably disposed on the inner wall of the main housing. The two vibrating wheels are meshed with transmission wheels on the axles at both ends of the synchronous belt. Vibrating connecting rods are eccentrically rotatably connected to the end faces of the two vibrating wheels. The vibrating connecting rods pass through the support platform inside the main housing and are rotatably connected to the lower end face of the paper storage frame. A driving component for driving the synchronous belt is also disposed on the outer wall of the main housing.

[0008] Preferably, guide rods are symmetrically arranged on the support platform inside the main housing. The guide rods are slidably connected to the guide holes at the lower end of the paper storage frame. A buffer spring is also sleeved on the outside of the guide rods. The outer wall of the paper storage frame is also slidably connected to the inner wall of the main housing by a sliding strip.

[0009] Preferably, the leveling member includes a sliding baffle, which is slidably connected to a groove on the sub-housing and located below the adsorption member. Magnetic elements are provided on the end of the sliding baffle and the inner wall of the groove to control the extension and retraction of the sliding baffle within the groove. A return spring is also provided on the end of the sliding baffle.

[0010] Preferably, the adsorption component includes an electric telescopic rod, a paper-separating nozzle, and a negative pressure pump. The electric telescopic rod and the negative pressure pump are disposed in the mounting groove inside the sub-housing housing. The paper-separating nozzle is installed at the output end of the electric telescopic rod and connected to the conduit of the negative pressure pump. An adjustable top plate is provided on the sub-housing housing through a sliding hole to prevent the paper from collapsing and to make it easier for the adsorbed edges to lift up and separate from the back paper.

[0011] Preferably, the detection unit includes two mounting strips, which are respectively attached to slots on the inner wall of the sub-housing along the horizontal and vertical directions. Several photoelectric sensors are arranged in an array on the two mounting strips. The mounting strip in the horizontal direction, near the lower end of the sub-housing, is used to detect the length of the paper, and the mounting strip in the vertical direction, located below the adsorption element, is used to detect the width of the paper. A light source matching the photoelectric sensors is provided in the slots on the inner wall of the main housing.

[0012] Preferably, the output archiving mechanism includes a multi-layer storage box, which is disposed at the lower end of the main housing. Sliding members are provided on both sides of the multi-layer storage box, and two retractable guide plates are rotatably connected between the sliding members. The other side of the two guide plates is rotatably connected to the embedded mounting plate and the lower end of the sub-housing, respectively, to guide the paper discharged from the conveying channel into the corresponding height of the multi-layer storage box.

[0013] Preferably, a controller is provided on the inner wall of the main housing, and the controller is electrically connected to the telescopic component, the adsorption component, the driving component, the magnetic component, the detection unit and the multi-layer storage box via wires.

[0014] Preferably, a set of conveying rollers is provided between the embedded mounting plate and the sub-shell and within the paper conveying channel for efficient paper transfer.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention, by setting up a paper-separating mechanism, enables various medical records documents in the paper storage frame to continuously move towards the lowest point of the collection position under the combined action of gravity and vibration, and complete edge alignment. Even if the paper has different lengths and widths, it can ensure that the ends to be absorbed are concentrated and exposed within the effective absorption range of the absorbent, thereby ensuring that the absorbent can stably absorb the local area of ​​the frontmost paper. After absorption, the absorbent is recycled, causing the absorbed end of the frontmost paper to lift up first, and then the auxiliary separation mechanism scrapes and separates the edge of the paper, forming a gap between it and the lower layer of paper and separating it from the paper stack. Throughout the process, the lower layer of paper will not be accidentally sucked out by the absorbent, thus ensuring that medical records documents of different sizes can be stably separated one by one, reducing the risk of consecutive sheets, duplicate sheets, and missed scans. It can also reduce the workload of manually picking up and putting in each page and sorting again after scanning when scanning a large number of various medical records documents, and improve the continuity and automation level of digital processing. 2. This invention, by setting up an auxiliary separation mechanism, utilizes the same driving component to simultaneously form the high-frequency micro-vibration of the paper storage frame and the reciprocating scraping of the paging scraper, so that pre-vibration alignment, single-sheet peeling, and next sheet replacement alignment can be continuously completed in the same mechanism. The integration and synchronization are high, ensuring the working efficiency of the entire device. The high-frequency micro-vibration is used to reduce the adhesion between papers and promote the paper stack to align towards the lower gathering position. The paging scraper is used to mechanically peel off the paper edge after the adsorption component forms a curled edge. The cooperation of the two consecutive actions further improves the adsorption success rate of papers of different sizes, and can also effectively reduce the problem of page contamination caused by old, damp, folded corners or static electricity in medical records. 3. By setting up a horizontal adjustment component, this invention effectively avoids the situation where the paper is attracted on one side and rotates on the other side due to gravity, and finally enters the conveyor channel for scanning in an inclined posture. The active correction of the falling posture improves the flatness and posture consistency of the paper when it enters the ADF scanner, thereby reducing the risk of skewed scanned images, missing edges and paper jams. 4. By setting up an adsorption component, the present invention uses a paper separation nozzle to accurately adsorb the corner of the foremost paper after the paper stack is pre-vibrated and aligned. When retracting, the paper twisting degree is significantly increased under the limitation of the top plate, which facilitates better separation from the paper behind, and further improves the reliability and stability of single-sheet separation of mixed medical records.

[0018] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0019] like Figure 1-13 As shown, an automatic scanning, sorting, and classifying device for medical records according to the present invention includes a main housing 1 and a secondary housing 2 arranged opposite to each other. The main housing 1 and the secondary housing 2 together constitute the main support structure of the device, forming an internal space between them for accommodating paper separation, scanning, detection, and output. An embedded mounting plate 3 is provided on the lower inner side of the secondary housing 2, with one side of the embedded mounting plate 3 arranged opposite to the inner wall of the secondary housing 2, forming a conveying channel for paper passage. This conveying channel can extend along the height direction of the device, or it can be configured with a channel structure having a certain guiding angle according to the position of the ADF scanner 5 and the output archiving mechanism 7, so that the paper stably passes through the scanning area under the combined action of its own weight, adsorption separation force, and conveying roller group 9.

[0020] Paper separating mechanisms 4 are installed on the main housing 1 and the sub-housing 2. These mechanisms carry the medical records to be scanned and separate sheets of paper that are stacked, have different sizes, thicknesses, or alignments. An ADF scanner 5 is horizontally mounted on the inner wall of the sub-housing 2 to scan the passing paper. The scanning window of the ADF scanner 5 faces the paper transport channel, allowing each sheet to be scanned as it passes through. A detection unit 6 is installed on the embedded mounting plate 3 and the lower inner wall of the sub-housing 2. This unit detects the size of the paper as it enters or passes through the transport channel. An output archiving mechanism 7 is located below the main housing 1 and the sub-housing 2. This mechanism receives the scanned paper and, based on the size information detected by the detection unit 6 or the classification logic of the controller 8, directs the paper to the corresponding storage location. A controller 8 is installed on the inner wall of the main housing 1. This controller 8 can be a microcontroller control board, a PLC control module, or other control devices capable of signal acquisition and execution control, receiving, judging, and controlling signals throughout the entire sorting and classification process.

[0021] Overall sorting and classification workflow: Staff place the medical records to be scanned into the paper sorting mechanism 4. The paper sorting mechanism 4 first supports and limits the paper stack, and then uses actions such as adsorption, vibration, scraping, and posture adjustment to peel the leading sheet of paper from the stack. The peeled paper enters the conveying channel formed by the embedded mounting plate 3 and the sub-housing 2, and then passes through the scanning area of ​​the ADF scanner 5 to complete image acquisition. As the paper continues to move downwards, the detection unit 6 reads the light-blocking status of the paper in the length and width directions, thereby obtaining paper size or category information. After scanning and size detection, the paper is discharged from the bottom of the conveying channel and guided by the output archiving mechanism 7 to the corresponding layer of the multi-layer storage box 701, realizing automatic sorting and storage after scanning.

[0022] The paper separating mechanism 4 includes a telescopic component 401, a paper storage frame 402, an auxiliary separating mechanism 404, and a horizontal adjustment component 405. The telescopic component 401 is located on one side of the bottom of the main housing 1. Figure 1 and Figure 2 As shown, the bottom of the main housing 1 includes a base plate, which is rotatably connected to one side of the main body of the main housing 1 via a hinge, and the other side is used to support the support foot of the telescopic component 401. When the telescopic component 401 extends, the entire automatic scanning and sorting device will rotate 2-5 degrees along the hinge. The telescopic component 401 can be an electro-hydraulic rod, a pneumatic-hydraulic support rod, or other actuators capable of telescopic support. One end of it is connected to the bottom of the device or the main housing 1, and the other end is connected to the support part of the main housing 1, used to change the tilt angle of the entire automatic scanning and sorting device relative to the horizontal plane.

[0023] The paper storage frame 402 is movably mounted on the support platform inside the main housing 1. The paper storage frame 402 has an open structure, allowing staff to place medical records into it from the top. The lower side wall of the paper storage frame 402 is slidably connected to the upper end of the embedded mounting plate 3. The inner side of the sub-housing 2 is provided with an adsorption element 403 for adsorbing the paper inside the paper storage frame 402 through an opening in the mounting groove. The adsorption end of the adsorption element 403 is located on one side of the sub-housing 2, corresponding to the gathering position of the paper. This gathering position refers to the point where, after the telescopic element 401 extends and drives the entire automatic scanning and sorting device to tilt, the paper will move towards the lower point under the action of gravity, in conjunction with the vibration generated by the auxiliary separation mechanism 404, until the bottom is in contact with the side and the paper storage frame 402.

[0024] The auxiliary separation mechanism 404 is mounted on the main housing 1 and located below the paper storage frame 402. The auxiliary separation mechanism 404 drives the paper storage frame 402 to vibrate at high frequency and simultaneously peels the adsorbed paper from the paper behind it. The horizontal adjustment component 405 is mounted in the mounting groove on the inner wall of the sub-housing 2 to guide the attitude of the peeled paper and ensure that the peeled paper falls in an attitude parallel to the ADF scanner 5.

[0025] The working principle of the paper separating mechanism 4: Before paper separation begins, the telescopic component 401 acts as a telescopic adjustment component, adjusting the tilt angle of the device according to the number of papers, paper thickness, or required paper feeding angle, so that the papers in the paper storage frame 402 naturally move towards the lower gathering position on the side of the adsorption component 403 under the action of gravity. At this time, the auxiliary separation mechanism 404 is activated first, causing the paper stack in the paper storage frame 402 to generate high-frequency micro-vibration. Since the device is in an inclined state, the papers that are not completely aligned with the lower gathering position will move downwards under the combined action of gravity and micro-vibration. In particular, the papers on the surface are less affected by the reaction force of the other papers, making it easier to complete edge alignment. Subsequently, the adsorption component 403 extends and adsorbs the corner of the lowest position of the foremost paper. Then, the adsorption component 403 retracts, causing the adsorbed end of the paper to tilt up, forming an initial separation gap between it and the paper behind it. Afterwards, the auxiliary separation mechanism 404 is activated again, scraping the lower edge of the adsorbed paper to create a gap between the adsorbed paper and the lower end of the paper behind it, gradually separating them completely. After the paper detaches from the paper stack, it falls onto the horizontal adjustment component 405. The horizontal adjustment component 405 is then opened, allowing the paper to enter the transport channel parallel to the ADF scanner 5, thus ensuring scanning quality. On the other hand, during the paper separation process by the auxiliary separation mechanism 404 and the resetting process of the page separating scraper 4044, the paper stack within the paper storage frame 402 continues to be subjected to high-frequency micro-vibration. This means that during and after the first sheet leaves the paper stack, the next sheet can synchronously align with the lower gathering position of the paper storage frame 402, preparing for the next paper separation. Once the first sheet has completely entered the transport channel, the suction component 403 can begin the suction operation for the next sheet.

[0026] By setting up the paper separation mechanism 4, various medical records documents in the paper storage frame 402 can continuously move towards the lowest point of the collection position under the combined action of gravity and vibration, and complete edge alignment. Even if the paper has different lengths and widths, the ends to be absorbed can be concentrated and exposed within the effective absorption range of the absorbent 403. This ensures that the absorbent 403 can stably absorb the local area of ​​the frontmost paper. After absorption, the absorbent 403 is recycled, causing the absorbed end of the frontmost paper to lift up first. Then, the auxiliary separation mechanism 404 scrapes and separates the edge of the paper, creating a gap between it and the lower layer of paper, and separating it from the paper stack separately. Throughout the process, the lower layer of paper will not be accidentally absorbed and carried out by the absorbent 403. This ensures that medical records documents of different sizes can be stably separated one by one, reducing the risk of consecutive sheets, duplicate sheets, and missed scans. It can also reduce the workload of manually picking up and putting in each page and sorting again after scanning when scanning a large number of various medical records documents, and improve the continuity and automation level of digital processing.

[0027] The auxiliary separation mechanism 404 includes a synchronous belt 4041, which is disposed on the inner wall of the main housing 1 below the paper storage frame 402. The synchronous belt 4041 can be supported by pulleys at both ends to form a closed-loop transmission path. The drive unit 4047 is disposed on the outer wall of the main housing 1 and can be a motor, a geared motor, or a servo motor. The output end of the drive unit 4047 is connected to the axle at one end of the synchronous belt 4041 to drive the synchronous belt 4041 to rotate cyclically.

[0028] A matching accessory 4042 is fixedly mounted on the synchronous belt 4041. The matching accessory 4042 can be a connecting block, a clamping block, or a fixing seat. A sliding sleeve 4043 is rotatably connected to the end of the matching accessory 4042 via a bearing. A piecing scraper 4044 is slidably connected inside the sliding sleeve 4043. The upper end of the piecing scraper 4044 is also slidably connected to a horizontal groove at the top of the embedded mounting plate 3. Thus, the upper end of the piecing scraper 4044 is constrained by the horizontal groove and can only reciprocate along a predetermined direction at the top of the embedded mounting plate 3; while its lower part is movably connected to the matching accessory 4042, which moves with the synchronous belt 4041, via the sliding sleeve 4043, allowing the cyclic motion of the synchronous belt 4041 to be converted into the reciprocating scraping motion of the piecing scraper 4044 along the horizontal groove.

[0029] Two vibrating wheels 4045 are symmetrically rotatably mounted on the inner wall of the main housing 1. These two vibrating wheels 4045 are meshed with transmission wheels on the axles at both ends of the synchronous belt 4041. Vibrating connecting rods 4046 are eccentrically rotatably connected to the end faces of the two vibrating wheels 4045. The vibrating connecting rods 4046 pass through the support platform inside the main housing 1 and are rotatably connected to the lower end face of the paper storage frame 402. When the synchronous belt 4041 rotates, its axles at both ends drive the vibrating wheels 4045 to rotate. The eccentric connection points on the vibrating wheels 4045 cause the vibrating connecting rods 4046 to periodically rise, fall, or swing, thereby causing the paper storage frame 402 to vibrate at high frequency. A touch switch can be installed at the end of the top groove of the embedded mounting plate 3 to determine whether the page divider 4044 has completed a single-stroke movement and to feed back the position signal to the controller 8, improving the accuracy of the entire control process.

[0030] The working principle of the auxiliary separation mechanism 404: The auxiliary separation mechanism 404 includes at least two working stages: pre-vibration alignment and scraping separation.

[0031] During the separation stage, once the adsorption element 403 has attracted the foremost paper and retracted it, causing the adsorbed end to tilt upwards, the drive element 4047 drives the synchronous belt 4041 to move. The matching accessory 4042 on the synchronous belt 4041 moves with the synchronous belt 4041 and pulls the piecing scraper 4044 along the horizontal groove at the top of the embedded mounting plate 3 via the sliding sleeve 4043. During the movement, the piecing scraper 4044 acts on the lower or side edge of the adsorbed paper, further widening the initial gap already opened by the adsorption element 403, so that the lower end of the paper gradually shifts away from the following paper and completely separates them.

[0032] Simultaneously, pre-vibration alignment is also performed. When the synchronous belt 4041 moves, the transmission wheels at both ends continue to drive the vibrating wheel 4045 to rotate. The eccentric connection point on the vibrating wheel 4045 drives the vibrating connecting rod 4046 to move periodically, thereby causing the paper storage frame 402 to generate high-frequency micro-vibration. This makes it easier for the paper stack, in an inclined state, to align with the lower gathering position on the side of the suction element 403. During the process of the paging scraper 4044 completing a single-pass scraping and resetting, the paper stack is still subjected to micro-vibration, allowing the next sheet of paper to smoothly align with the lower gathering position. The touch switch at the end of the chute can be used to determine whether the paging scraper 4044 has completed a single-pass movement and to send a scraping completion signal to the controller 8 for calibration.

[0033] By setting up an auxiliary separation mechanism 404, the same driving component 4047 simultaneously forms the high-frequency micro-vibration of the paper storage frame 402 and the reciprocating scraping of the paging scraper 4044, enabling pre-vibration alignment, single-sheet peeling, and next sheet replacement alignment to be completed continuously in the same mechanism. The integration and synchronization are high, ensuring the working efficiency of the entire equipment. The high-frequency micro-vibration is used to reduce paper adhesion and promote the paper stack to align towards the lower gathering position. The paging scraper 4044 is used to mechanically peel the paper edge after the adsorption component 403 forms a curled edge. The coordination of the two consecutive actions further improves the adsorption success rate of paper of different sizes and can also effectively reduce the problem of page separation caused by old, damp, folded, or static electricity in medical records.

[0034] like Figure 7 and Figure 8 As shown, guide rods 4048 are symmetrically arranged on the support platform inside the main housing 1. The guide rods 4048 are slidably connected to the guide holes opened at the lower end of the paper storage frame 402. A buffer spring 4049 is also sleeved on the outside of the guide rods 4048. The outer wall of the paper storage frame 402 is also slidably connected to the inner wall of the main housing 1 by a sliding strip. The sliding strip cooperates with the corresponding sliding groove on the inner wall of the main housing 1 to keep the paper storage frame 402 directionally stable during vibration. The stability of the paper storage frame 402 can also be further improved by setting guide rods 4048 and buffer springs 4049 at the upper connection between the main housing 1 and the paper storage frame 402.

[0035] The horizontal adjustment component 405 includes a sliding baffle 4051, which is slidably connected to a groove on the sub-housing 2 and located below the adsorption component 403. The sliding baffle 4051 can be a thin plate, a strip, or a plate with an arc-shaped guide surface, and its inclination direction corresponds to the direction in which the paper transitions from the paper storage frame 402 to the conveying channel. A magnetic attractor 4052 is provided at the end of the sliding baffle 4051 and on the inner wall of the groove. The magnetic attractor 4052 can be a combination of an electromagnet and a ferromagnetic attracting block, or a combination of an electromagnet and a permanent magnet, used to control the extension and retraction of the sliding baffle 4051 within the groove. A return spring 4053 is also provided at the end of the sliding baffle 4051 to reset the sliding baffle 4051 after the magnetic attractor 4052 is released or the power is cut off.

[0036] The working principle of the horizontal adjustment component 405 is as follows: When the suction component 403 suctions and retracts the paper, causing the paper to partially lift, and the pagination scraper 4044 of the auxiliary separation mechanism 404 completes edge scraping, the controller 8 should control the magnetic suction component 4052 to be energized, causing the sliding baffle 4051 to extend along the groove on the sub-housing 2 to the paper's falling path to receive the paper. After the paper has completely fallen onto the sliding baffle 4051, the controller 8 controls the magnetic suction component 4052 to be de-energized, and the sliding baffle 4051 is reset and retracted under the action of the reset spring 4053. After losing its support, the paper enters the transport channel in an orientation suitable for scanning by the ADF scanner 5, and moves under the drive of the transport roller group 9 to complete the scanning. After the paper has completely entered the transport channel, the controller 8 controls the magnetic suction component 4052 to be energized again to drive the sliding baffle 4051 to reset, ready to receive the next medical record paper.

[0037] By setting the horizontal adjustment component 405, the situation where the paper is attracted on one side and rotated on the other side due to gravity, and finally enters the conveyor channel for scanning in an inclined posture is effectively avoided. The active correction of the falling posture improves the flatness and posture consistency of the paper when it enters the ADF scanner 5, thereby reducing the risk of skewed scanned images, missing edges and paper jams.

[0038] like Figure 3-8 As shown, the suction component 403 includes an electric telescopic rod 4031, a paper-separating suction nozzle 4032, and a negative pressure pump 4033. The electric telescopic rod 4031 and the negative pressure pump 4033 are disposed in the mounting groove inside the sub-housing 2, with the output end of the electric telescopic rod 4031 facing the paper accumulation position in the paper storage frame 402. The paper-separating suction nozzle 4032 is installed at the output end of the electric telescopic rod 4031 and connected to the conduit of the negative pressure pump 4033. The paper-separating suction nozzle 4032 can be a flexible suction cup, a flat suction nozzle, or a multi-hole suction nozzle to adapt to situations where the surface of medical record documents is not completely flat. An adjustable top plate 4034 is provided on the sub-housing 2 through a sliding hole. Figure 7As shown, the upper and lower ends of the top plate 4034 are positioned with the sub-shell 2 by means of openable limiting members. The top plate 4034 limits the lower part of the paper. After the surface paper is adsorbed and pulled away, the limiting function of the top plate 4034 can increase the degree of twisting of the adsorbed paper, making it easier to separate from the lower layer of paper. At the same time, the top plate 4034 can also prevent the paper from collapsing. The contact surface between the top plate 4034 and the paper is provided with a sliding roller to reduce the impact of friction on the downward movement of the paper.

[0039] The working principle of the adsorption element 403 is as follows: After the auxiliary separation mechanism 404 completes the pre-vibration alignment, the electric telescopic rod 4031 extends and drives the paper separation nozzle 4032 to approach the edge of the foremost paper at the low-position gathering location. After the negative pressure pump 4033 starts, a negative pressure is formed at the paper separation nozzle 4032, causing the paper separation nozzle 4032 to suck up the edge of the paper. Subsequently, the electric telescopic rod 4031 retracts, pulling the edge of the adsorbed paper towards the sub-shell 2, causing the adsorbed end of the paper to tilt relative to the paper behind it, forming an initial separation gap between the two. The top plate 4034 supports and limits the paper stack, preventing the entire paper stack from collapsing towards the adsorption element 403. At the same time, it makes the local tilting angle of the adsorbed paper larger, which is convenient for separation from the paper behind it, and also facilitates the subsequent scraping of the lower end or edge of the paper by the piecing scraper 4044.

[0040] By setting up the adsorption component 403, a paper separation nozzle 4032 is used to precisely adsorb the corner of the foremost paper after the paper stack is pre-vibrated and aligned. When retracting, the paper twisting degree is significantly increased under the limit of the top plate 4034, which facilitates better separation from the paper behind, and further improves the reliability and stability of single-sheet separation of mixed medical records.

[0041] The detection unit 6 includes two mounting straps 601, which are respectively attached to slots on the inner wall of the sub-housing 2 in the horizontal and vertical directions. Several photoelectric sensors 602 are arrayed on the two mounting straps 601. The horizontal mounting strap 601, near the lower end of the sub-housing 2, is used to detect the obstruction range in the paper's length direction to determine the paper's length. The vertical mounting strap 601, located below the adsorption member 403, is used to detect the obstruction range in the paper's width direction. A light source 603, matching the photoelectric sensors 602, is installed in a slot on the inner wall of the main housing 1. Glass plates can be attached to both the sub-housing 2 and the main housing 1, located on either side of the paper conveying channel. The glass plates facilitate the passage of light emitted by the light source 603 and its reception by the photoelectric sensors 602, while also ensuring the smooth passage of the paper.

[0042] The working principle of detection unit 6: Before the scanned paper enters the detection area, the light source 603 emits a stable light signal to the corresponding photoelectric sensor 602, and the photoelectric sensor 602 is in receiving mode. When the paper passes through the conveyor channel, the paper will block part of the light path, causing the signal of the photoelectric sensor 602 at the corresponding position to change. The controller 8 determines the paper width based on the number, position, or combination of the blocked photoelectric sensors 602 on the vertical mounting belt 601; and determines the paper length based on the change in the number and position of the blocked photoelectric sensors 602 on the horizontal mounting belt 601. For medical records of different sizes, the controller 8 can identify the paper as A4, A5, long strip tickets, examination forms, or other custom categories according to a preset size threshold, and transmit this category information to the output archiving mechanism 7.

[0043] The function of the detection unit 6 is to determine the size of the paper in advance, so that the controller 8 can guide its output to the designated storage location in the multi-layer storage box 701. It is not for use with the ADF scanner 5, whose scanning area is fixed as long as it is larger than the width of the paper.

[0044] The output archiving mechanism 7 includes a multi-layer storage box 701, which is located at the lower end of the main housing 1 and is used to receive scanned paper discharged from the paper transport channel. The multi-layer storage box 701 can be configured as a multi-layer drawer structure, a partitioned slot structure, or a detachable box structure, with each layer corresponding to medical records of different sizes, categories, or processing states. Sliding members 702 are provided on both sides of the multi-layer storage box 701. The sliding members 702 are driven to rise and fall by drive devices on both sides of the multi-layer storage box 701. Two retractable guide plates 703 are rotatably connected between the sliding members 702. The other side of the two guide plates 703 is rotatably connected to the embedded mounting plate 3 and the lower end of the sub-housing 2, respectively, to guide the paper discharged from the transport channel into the multi-layer storage box 701 at the corresponding height. Drive rollers can be further provided at the entrance of each layer of the multi-layer storage box 701 to provide power for the paper to enter, ensuring that the paper can completely enter the multi-layer storage box 701.

[0045] The working principle of the output archiving mechanism 7 is as follows: After the paper is scanned and its size is detected, the controller 8 determines the target storage layer based on the paper type obtained by the detection unit 6. Then, the sliding members 702 on both sides of the multi-layer storage box 701 move to the corresponding storage height. The two retractable guide plates 703 extend, retract, and rotate with the position changes of the sliding members 702, creating a continuous transition surface between the conveyor channel outlet and the target storage layer inlet. After the paper is discharged from the conveyor channel, it rests against the guide surface formed by the guide plates 703 and slides along the guide surface into the target layer of the multi-layer storage box 701.

[0046] By setting up the output archiving mechanism 7, scanned papers can be directly imported into the corresponding layer, avoiding manual sorting by staff after scanning. Two retractable guide plates 703 and sliding parts 702 work together to allow the same conveyor outlet to accommodate storage layers of multiple heights. The structure is compact and the classification path is clear, which improves the archiving efficiency of scanned medical records and reduces sorting errors caused by mixing different sizes of paper.

[0047] The controller 8 is electrically connected to the telescopic component 401, the suction component 403, the driving component 4047, the magnetic suction component 4052, the detection unit 6, and the multi-layer storage box 701 via wires. The controller 8 can also be connected to the touch switch corresponding to the paging scraper 4044, the driving component of the conveyor roller group 9, the alarm, or the display panel to realize status feedback and human-machine interaction.

[0048] The entire control process of controller 8 is described as follows: After the device is started, controller 8 first controls the telescopic component 401 to adjust the device tilt angle according to the preset program, so that the paper in the paper storage frame 402 tends to move towards the lower gathering position on the side of the suction component 403. Then, controller 8 controls the drive component 4047 to start, so that the auxiliary separation mechanism 404 first performs a pre-vibration alignment action, using the high-frequency micro-vibration of the paper storage frame 402 and gravity to make the paper stack move closer to the lower gathering position. After alignment is completed, controller 8 controls the suction component 403 to perform extension, suction and retraction actions, so that the suction end of the frontmost paper is lifted. Then, controller 8 controls the drive component 4047 to make the page separation scraper 4044 scrape the edge of the suction paper, and continues to drive the paper storage frame 402 to vibrate micro-vibrate during the scraping and resetting process, so that the next paper is synchronously aligned, and the electrical signal emitted by the touch switch is used for calibration. After the paper enters the conveying channel, the controller 8 controls the magnetic suction component 4052 to drive the sliding baffle 4051 to extend and retract in a timely manner, and receives the size signal transmitted back by the detection unit 6. Finally, based on the detection result, the controller controls the multi-layer storage box 701 or the sliding component 702 to move so that the paper enters the corresponding storage layer.

[0049] A conveyor roller assembly 9 is installed between the embedded mounting plate 3 and the sub-housing 2, located within the paper transport channel, for efficient paper transfer. The conveyor roller assembly 9 consists of several conveyor rollers, providing active traction and speed control for the movement of paper within the transport channel, reducing the uncontrollable posture problems caused by free-falling paper. When this structure is used in conjunction with the ADF scanner 5, the detection unit 6, and the output archiving mechanism 7, it can improve the stability of scanned images and the efficiency of paper transfer, reducing the risk of thin paper, old paper, or small-sized documents getting stuck, shifted, or jammed in the channel.
