Description

Technical Field

[0001] This application relates to a document inspection system, and more specifically, to an automatic clamping mechanism applied to document inspection. Background Art

[0002] In customs clearance places such as security checks, it is necessary to inspect document files. During the document inspection process, operations such as document scanning, page turning, stamping, and labeling of documents are involved. In most cases, these operations are completed manually, which is not only time-consuming and laborious but also has low efficiency. Especially when dealing with the signing, stamping, and scanning of paper documents with a large number of pages, non-automated manual page turning increases the burden on staff.

[0003] If an automatic document inspection system is used to uniformly complete operations such as document page turning, stamping, and labeling, then the automatic document inspection system needs to have mechanisms for transporting and clamping documents to move them to the page turning station, stamping station, and labeling station. Some commonly used clamping mechanisms in the prior art, such as electric or pneumatic chucks, but this method requires the use of motors or air claws, resulting in the access of wire cables or air circuits. In this way, when the wire cables of the electric or pneumatic chucks are arranged and transported to different stations, the wire cables will inevitably affect the cyclic transport movement process. Summary of the Invention

[0004] In view of the prior art, the technical problem solved by this application is to provide an automatic clamping mechanism applied to a document inspection system that does not adopt an electrical cable structure, avoiding the phenomenon that the wire cables affect the cyclic transport movement process when the documents placed on the automatic clamping mechanism are transported to different stations.

[0005] To solve the above technical problem, in a first aspect, this application provides an automatic clamping mechanism applied to document inspection, which includes:

[0006] A substrate;

[0007] A supporting plate spaced from the substrate and sliding up and down relative to the substrate;

[0008] A first elastic member with two ends respectively connected to the substrate and the supporting plate;

[0009] A plurality of hooks rotatably connected to the substrate, each of the hooks rotatably clamping at the edge of the supporting plate;

[0010] A plurality of second elastic members arranged in one-to-one correspondence with the plurality of hooks, one end of each second elastic member connected to the hook and the other end connected to the substrate; and,

[0011] A plurality of rollers arranged in one-to-one correspondence with the plurality of hooks, each of the rollers fixedly arranged at the edge of the supporting plate and in sliding contact with one of the hooks.

[0012] In an embodiment of the application, the automatic clamping mechanism further includes a plurality of sliding rods fixedly arranged on the supporting plate; each of the sliding rods can slidably penetrate through the substrate, and a first elastic member is sleeved on each of the sliding rods.

[0013] In an embodiment of the application, the supporting plate includes two trays, and a plurality of the sliding rods slidably connected to the substrate are arranged on each of the trays.

[0014] In an embodiment of the application, two middle guiding columns are fixedly arranged on the substrate, the two middle guiding columns are respectively slidably connected to the middles of the two trays, and a plurality of the sliding rods on each of the trays are arranged around one of the middle guiding columns slidably connected to the tray.

[0015] In an embodiment of the application, a pin is arranged at the end of the sliding rod penetrating through the substrate.

[0016] In an embodiment of the application, clamping holes are formed at the opposite edges of each of the trays; a roller is located in one of the clamping holes, and a hook in sliding contact with the roller rotates at the clamping hole.

[0017] For the automatic clamping mechanism applied to the document verification system provided by the present application, when a document is placed on the supporting plate, since the document exerts a force on the supporting member, the supporting member moves downward towards the substrate, and the rollers on the supporting plate also move downward accordingly. The hook in contact with the roller will be pressed down by the roller, so that the hook clamped at the edge of the supporting plate has a tendency to open; at the same time, when the document on the supporting plate is taken away, the external force of the document is withdrawn. Under the action of the first elastic member, the supporting plate will move upward away from the substrate, and at the same time, under the action of the second elastic member, the hook will also reset; in this way, during the process of placing and removing external objects, the automatic clamping mechanism can automatically realize the opening and resetting of the hook, and the automatic clamping mechanism does not adopt an electrical cable structure, thus avoiding the phenomenon that the cable affects the circular conveying movement process when the document placed on the automatic clamping mechanism is conveyed to different workstations.

[0025] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present application, "a plurality" means two or more unless otherwise specifically defined.

[0026] The automatic clamping mechanism of the present application will be specifically described below with reference to the accompanying drawings.

[0027] The automatic clamping mechanism provided by the embodiment of the present application is applied to a document inspection system. There are multiple working stations in the multi-station document inspection system, including working stations such as a document page-turning station, a document scanning and recognition station, and a document stamping station. A document page-turning mechanism for turning the document is provided at the document page-turning station, an automatic stamping machine is provided at the document stamping station for automatically stamping the document, and a document OCR recognizer is provided at the document scanning and recognition station. The automatic clamping mechanism can move among the above-mentioned multiple working stations, and can be used to transport and clamp the document to each working station for related operations.

[0028] With reference to Figure 1 and Figure 2 , the automatic clamping mechanism 100 includes a substrate 10, a supporting plate 20, a first elastic member 30, a plurality of hooks 40, a plurality of second elastic members 50 provided in one-to-one correspondence with the plurality of hooks 40, and a plurality of rollers 60 provided in one-to-one correspondence with the plurality of hooks 40.

[0029] Among them, the supporting plate 20 is spaced from the substrate 10 and slides up and down relative to the substrate 10. Two ends of the first elastic member 30 are respectively connected to the substrate 10 and the supporting plate 20. Each hook 40 is rotatably connected to the substrate 10 and rotatably clamped to the edge of the supporting plate 20. One end of each second elastic member 50 is connected to the hook 40 and the other end is connected to the substrate 10. Each roller 60 is fixedly arranged at the upper edge of the supporting plate 20 and is in sliding contact with a hook 40.

[0030] In the above automatic clamping mechanism 100, when a document is placed on the supporting plate 20, since the document exerts a force on the supporting member, the supporting plate 20 moves downward towards the substrate 10, and the rollers 60 on the supporting plate 20 also move downward accordingly. The hook 40 in contact with the roller 60 will be pressed down by the roller 60, so that the hook 40 clamped to the edge of the supporting plate 20 has a tendency to open. At the same time, when the document on the supporting plate 20 is taken away, the external force of the document is withdrawn. Under the action of the first elastic member 30, the supporting plate 20 will move upward away from the substrate 10, and at the same time, under the action of the second elastic member 50, the hook 40 will also reset. In this way, during the process of placing and removing the external object, the automatic clamping mechanism 100 can automatically realize the opening and resetting of the hook 40, and the automatic clamping mechanism 100 does not adopt an electrical cable structure, so as to avoid the influence of the cable on the cyclic transmission movement process when the document placed on the automatic clamping mechanism 100 is transmitted to different stations.

[0031] As Figure 2As shown, the automatic clamping mechanism 100 further includes a plurality of sliding rods 70 fixedly disposed on the supporting plate 20; each sliding rod 70 can slide through the base plate 10, and each sliding rod 70 is sleeved with the aforementioned first elastic member 30. When the document is placed on the supporting plate 20 to cause the supporting plate 20 to move downward, the sliding rod 70 on the supporting plate 20 slides on the base plate 10.

[0032] Furthermore, a pin is provided on the end of the sliding rod 70 that passes through the base plate 10. The pin provided on the sliding rod 70 can limit the movement stroke of the supporting plate 20.

[0033] Furthermore, the supporting plate 20 includes two trays 21 , and each tray 21 is provided with a plurality of sliding rods 70 slidably connected to the base plate 10 .

[0034] Furthermore, each tray 21 has a clamping hole 211 at the opposite edge; a roller 60 is located in a clamping hole 211 and a hook 40 in sliding contact with the roller 60 rotates at the clamping hole 211. The hook 40 is bent and extended from the side of the support plate 20 facing the base plate 10 to the side of the support plate 20 facing away from the base plate 10, and after the hook 40 is opened due to the effect of the document, the hook 40 opens outward relative to the tray 21 at the clamping hole of the tray 21 but does not completely detach from the edge of the tray 21, so that after the document is placed, the hook 40 does not hinder the subsequent page turning operation of the document, and the multiple hooks 40 also play a role of enclosure at the edge of the support.

[0035] like Figure 2 and Figure 3 As shown, two middle guide posts 80 are fixedly arranged on the base plate 10, and the two middle guide posts 80 are respectively slidably connected to the middle parts of the two trays 21, and the plurality of sliding rods 70 on each tray 21 are arranged around a middle guide post 80 slidably connected to the tray 21. In this way, the cooperation between the middle guide post 80 and the plurality of sliding rods 70 arranged around the middle guide post 80 enables the support plate 20 to slide more smoothly.

[0036] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
