It can examine various types of documents and is used to assist in the investigation of document forgery or tampering. It can display a variety of security features of the document.

[0003] For example, utility model patent application number 202122623549.4 discloses an autofocus camera document inspection instrument, including a base, a chassis at the top of the base, a display screen hinged to the top of the chassis, a protective shell at the bottom of the chassis, a lifting plate slidably connected inside the protective shell, and a camera at the bottom of the lifting plate.

[0004] Based on existing technology, most document inspection instruments have limited functions and cannot automatically correct deviations after the documents to be inspected are placed, which easily leads to the documents being skewed and affects the normal progress of document inspection. In addition, manual operation is required to pick up and put down the documents for inspection, resulting in low automation and inconvenience. Therefore, this utility model proposes a multi-functional document inspection instrument to solve the problems existing in the prior art. Utility Model Content

[0005] To address the aforementioned problems, the purpose of this utility model is to propose a multifunctional document inspection instrument that solves the issues of existing document inspection instruments lacking automatic position correction for documents to be inspected and requiring manual operation for picking up and placing documents, resulting in a low degree of automation.

[0006] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a multifunctional document inspection instrument, including a base, an inspection box fixed at the top of the base, a camera and a light source fixed at the top of the inspection box, a document placement plate slidably disposed at the top of the base and driven to move by a gear drive mechanism, an inlet and outlet opening on the front of the inspection box, first correction plates driven to move by a longitudinal movement drive mechanism on both the front and rear sides of the top of the document placement plate, and second correction plates driven to move by a transverse movement drive mechanism on both the left and right sides of the top of the document placement plate, with sliders fixed at equal distances at the bottom of the first and second correction plates, and a sliding groove adapted to the sliders opening at the top of the document placement plate.

[0007] A further improvement is that the front side of the inspection box is equipped with a door that is driven to rise and fall by a cylinder and is adapted to the inlet and outlet. A display screen that is electrically connected to the camera is fixed on the front of the door.

[0008] A further improvement is that the gear drive mechanism includes a through slot located in the middle of the base and a gear rotatably connected inside the through slot and driven to rotate by a servo motor. A rack that meshes with the gear is fixed at the bottom of the document placement plate.

[0009] Further improvements include: limiting blocks are fixed to the rear of the outer walls on both sides of the document placement plate; limiting slide rails adapted to the limiting blocks are symmetrically fixed to the top of the base; limiting grooves adapted to the limiting blocks are opened on the side of the limiting slide rails near the document placement plate; and support rollers that abut against the bottom of the document placement plate are rotatably connected to both sides of the top of the base.

[0010] A further improvement is that the longitudinal movement drive mechanism includes a bidirectional lead screw that is rotatably connected inside the document placement plate and driven to rotate by a first rotary motor. Both sides of the bidirectional lead screw are threaded with threaded plates, and the top of the threaded plates slides through the document placement plate and is fixed to the bottom of the first correction plate.

[0011] A further improvement is that the transverse drive mechanism includes a frame fixed to the inner walls of both sides of the inspection box and a one-way lead screw rotatably connected inside the frame and driven to rotate by a second rotary motor. An L-shaped support plate fixedly connected to the second correction plate is threaded onto the one-way lead screw.

[0012] A further improvement is that threaded posts are fixed at the four corners of the bottom of the base, and threaded sleeves are threaded onto the threaded posts. A positioning suction cup is rotatably connected to the bottom of the threaded sleeves.

[0013] The beneficial effects of this utility model are as follows: This utility model includes a base, on which the document to be inspected is placed via a document placement plate at the top of the base.

[0018] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0019] according to Figure 1 , Figure 2 , Figure 3 As shown, this embodiment provides a multifunctional document inspection instrument, including a horizontally arranged base 1 and an inspection box 2 fixed to the top of the base 1 by bolts. The inspection box 2, together with the base 1, forms a relatively enclosed inspection space. A camera 3 for photographing inspection documents is fixed to the top of the inspection box 2 by bolts. Light sources 4 are provided on both sides of the camera 3, which are suspended from the top of the inspection box 2 and used to provide illumination for the shooting environment, so as to facilitate the camera 3 to take pictures. A document placement plate 5 for placing the document to be inspected is slidably provided on the top of the base 1, and the document placement plate 5 is driven by a gear drive mechanism inside the base 1 to move back and forth longitudinally. The bottom of the front side wall of the inspection box 2 has an inlet / outlet 6 adapted to the document placement plate 5 so that the document placement plate 5 can enter and exit the inspection box 2. The document to be inspected is placed through the document placement plate 5 at the top of the base 1, and the document placement plate 5 is driven by the gear drive mechanism to move back and forth longitudinally, so that the document to be inspected can be automatically put into or taken out of the inspection box 2.

[0020] The top front and rear sides of the document placement plate 5 are provided with first correction plates 7, and the two sets of first correction plates 7 are driven by the longitudinal movement drive mechanism inside the document placement plate 5 to move in opposite directions or towards each other. The top left and right sides of the document placement plate 5 are provided with second correction plates 8, and the two sets of second correction plates 8 are driven by the transverse movement drive mechanism on the inner walls of the left and right sides of the inspection box 2 to move in opposite directions or towards each other. The bottom ends of the first correction plates 7 and the second correction plates 8 are fixed with sliders 9 at equal intervals. The top of the document placement plate 5 is provided with a sliding groove adapted to the sliders 9. The sliders 9 slide in the sliding groove, which can prevent the document to be inspected from entering the gap between the first correction plates 7 and the second correction plates 8 and the document placement plate 5. This ensures that the first correction plates 7 and the second correction plates 8 move while driving the document to be inspected to move synchronously, thereby achieving position correction. The longitudinal movement drive mechanism and the transverse movement drive mechanism drive the two sets of first correction plates 7 and the two sets of second correction plates 8 to move in opposite directions, thereby achieving automatic correction of the document to be inspected and preventing it from becoming skewed during the inspection process.

[0021] The front of the inspection box 2 is equipped with two sets of cylinders 10 that are symmetrically distributed on the left and right. The output ends of the two sets of cylinders 10 are fixed to the box door 11 by bolts. The box door 11 is adapted to the inlet and outlet 6 and is used to close the inspection box 2. The front of the box door 11 is fixed to the display screen 12 by bolts. The camera 3 is connected to the PLC control system of the document inspection instrument and is used to transmit the captured inspection results to the display screen 12 for display.

[0022] The gear drive mechanism includes a through slot 13, a servo motor 14, and a rotating gear 15. The through slot 13 is located in the middle of the base 1. The rotating gear 15 is rotatably connected to the inside of the through slot 13 via a bearing and is driven to rotate by the servo motor 14 inside the base 1. A rack 16 is fixed to the bottom of the document placement plate 5 by bolts, and the rack 16 meshes with the gear 15. The servo motor 14 drives the rotating gear 15 to rotate. While the rotating gear 15 rotates, it drives the rack 16 to move longitudinally back and forth. The rack 16 moves synchronously, causing the document placement plate 5 to move synchronously.

[0023] Limiting blocks 17 are welded and fixed to the rear of the outer walls on both sides of the document placement plate 5. Limiting slide rails 18 are symmetrically fixed to the top of the base 1. The limiting slide rail 18 has a limiting groove that matches the limiting block 17 on the side near the document placement plate 5. The limiting block 17 extends into the limiting groove on the limiting slide rail 18 to limit the document placement plate 5. Support rollers 19 are rotatably connected to the left and right sides of the top of the base 1, and the support rollers 19 abut against the bottom of the document placement plate 5 to provide auxiliary support for the document placement plate 5.

[0024] The longitudinal movement drive mechanism includes a first rotary motor 20 and a bidirectional lead screw 21. The first rotary motor 20 is fixed to the outer rear wall of the document placement plate 5 by bolts. The bidirectional lead screw 21 is rotatably connected to the inside of the document placement plate 5 through bearings and is driven to rotate by the first rotary motor 20. Both sides of the bidirectional lead screw 21 are threaded with threaded plates 22 with opposite threading directions. The top of the threaded plate 22 slides through the document placement plate 5 and is fixed to the bottom of the first correction plate 7 by bolts. The top of the document placement plate 5 has a through groove for the threaded plate 22 to slide through. The first rotary motor 20 drives the bidirectional lead screw 21 to rotate, so that the threaded plates 22 threaded on both sides of the bidirectional lead screw 21 drive the two sets of first correction plates 7 to move in opposite directions or towards each other.

[0025] The lateral movement drive mechanism includes a frame 23, a second rotary motor 24, and a one-way lead screw 25. The frame 23 has two sets of screws that are fixed to the inner walls of the left and right sides of the inspection box 2. The second rotary motor 24 has two sets of screws that are fixed to the outer walls of the left and right sides of the inspection box 2. The one-way lead screw 25 is rotatably connected to the inside of the frame 23 through bearings and is driven to rotate by the second rotary motor 24. An L-shaped support plate 26 is threaded onto the one-way lead screw 25. The L-shaped support plate 26 slides against the inner wall of the frame 23. The bottom end of the L-shaped support plate 26 is bent at a 90-degree angle and is fixedly connected to the second correction plate 8 by bolts. The one-way lead screw 25 is rotated by the second rotary motor 24, causing the L-shaped support plate 26 threaded onto the one-way lead screw 25 to move laterally to the left and right sides.

[0026] Threaded posts 27 are fixed in the grooves at the four corners of the bottom of the base 1. Threaded sleeves 28 are threaded onto the threaded posts 27. The bottom of the threaded sleeves 28 is rotatably connected to a positioning suction cup 29. The positioning suction cup 29 provides support and positioning for the base 1. The threaded sleeves 28 can rotate and rise on the threaded posts 27, which can adjust the support height to a certain extent.

[0027] First, start the cylinder 10 to drive the box door 11 to rise until the inlet / outlet 6 is exposed. Then, use the gear drive mechanism to drive the document placement plate 5 to move from back to front until it is removed from the inspection box 2 (with the cooperation of the limit block 17 and the limit slide rail 18, the document placement plate 5 can be prevented from falling off). Then, the user places the document to be inspected on the surface of the document placement plate 5, between the two sets of first correction plates 7. Then, use the gear drive mechanism to drive the document placement plate 5 to move from front to back until it is moved into the inspection box 2. At this time, start the cylinder 10 to drive the box door 11 to descend until the inlet / outlet 6 is closed, thus realizing the automated picking and placing of inspection documents.

[0028] After the document to be inspected is moved into the inspection box 2, the longitudinal drive mechanism drives the two sets of first correction plates 7 to move towards each other to perform front-to-back position correction calibration on the document to be inspected. At the same time, the transverse drive mechanism drives the two sets of second correction plates 8 to move towards each other to perform left-to-right position correction calibration on the document to be inspected. Through the limiting in four directions, the document to be inspected is placed at the center position on the upper surface of the document placement plate 5, completing the automatic position correction. At this time, the document to be inspected is directly below the camera 3. Then, the light source 4 is turned on to illuminate the document to be inspected, and the camera 3 is turned on to take a picture of the document to be inspected and transmit the inspection result to the display screen 12 for display, thus completing the document inspection work.
