[0025] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. Throughout the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0026] The lifting mechanism and the stamping machine of the present application are now described in detail with reference to the accompanying drawings.

[0027] Refer to Figure 1 and Figure 2 The lifting mechanism 100 of the stamping machine provided in the embodiment of the present application includes a base 10, a lifting drive mechanism 20 arranged on the base 10, a lifting member 30, a limit block 40 fixedly arranged on the lifting member 30 and in surface contact with the lifting drive mechanism 20, and a plurality of guide rods 50 arranged perpendicular to the lifting member 30. Specifically, one end of each of the guide rods 50 is fixedly arranged on the base 10 and the other end is slidably connected to the lifting member 30; the document 200 to be stamped is arranged on the lifting member 30, and the lifting drive mechanism 20 is used to drive the lifting member 30 fixedly connected to the limit block 40 to slide up and down along the plurality of guide rods 50, so as to drive the document 200 on the lifting member 30 to move up and down. The direction of the up and down sliding and the direction of the up and down movement are as shown in FIG. Figure 1 The arrow indicates the direction.

[0028] Further references Figure 1 The lifting drive mechanism 20 includes a motor 21 mounted on the base 10, a crankshaft 22 rotatably connected to the motor 21, and a bearing 23 fixedly connected to the crankshaft 22. The stopper 40 is in surface contact with the bearing 23; the motor 21 is used to drive the crankshaft 22 to rotate, thereby driving the stopper 40 in contact with the bearing 23 to move up and down.

[0029] In the jacking mechanism, the jacking drive mechanism is used to drive the jacking member fixedly connected to the limit block to slide up and down along the multiple guide rods, so as to drive the document on the jacking member to move up and down; the jacking mechanism can effectively and automatically drive the document on the jacking member to slide up and down, and can automatically lift the document to the stamping position, which is conducive to automatic stamping and reduces manual participation in the stamping process.

[0030] Combined with reference Figure 2 and Figure 3 The lifting member 30 includes a support plate 31, a lifting platform 32 stacked with the support plate 31, and a plurality of springs 33 corresponding to the plurality of guide rods 50. The limit block 40 is fixedly arranged on the support plate 31. One end of each guide rod 50 that is slidably connected to the lifting member 30 is used to penetrate and slidably connect to the support plate 31, and the side of the lifting platform 32 away from the support plate 31 is used to place the certificate 200 to be stamped. When the lifting drive mechanism 20 is used to drive the lifting member 30 to move, the plurality of guide rods 50 penetrate the support plate 31, and each spring 33 is used to be sleeved on the guide rod 50 corresponding to the spring 33.

[0031] When stamping the document 200 on the top delivery platform 32, the stamping mechanism is set on the side of the document 200 to be stamped away from the top delivery platform 32. Since the support plate 31 and the top delivery platform 32 are connected by an elastically deformable spring 33, the lifting mechanism 100 can adapt to documents 200 of different thicknesses.

[0032] It can be understood that during the movement of the lifting mechanism 100, the motor 21 drives the crankshaft 22 to rotate. During the rotation of the crankshaft 22, the bearing 23 rotates, thereby pushing the limit block 40 in contact with the bearing 23 to move up and down. When the limit block 40 moves, it drives the support plate 31 fixedly connected to it to move. Since the lifting platform 32 is connected to the support plate 31 by the spring 33, the lifting platform 32 also moves up and down with the support plate 31.

[0033] Further references Figure 3 The lifting platform 32 includes a lifting plane 321 for placing the document 200 to be stamped and multiple side surfaces 322 perpendicularly connected to the lifting plane 321; the multiple side surfaces 322 are connected end to end in sequence, the support plate 31 connects the multiple side surfaces 322 and the base 10 and the lifting plane 321 are arranged in parallel; the lifting drive mechanism 20, the support plate 31 and the multiple guide rods 50 are located between the lifting platform 32 and the base 10.

[0034] As can be understood, the lifting platform 32 is stacked with the base 10, with the lifting drive mechanism 20, support plate 31, and multiple guide rods 50 located between the lifting platform 32 and the base 10. The lifting platform 32 and the support plate 31 form a rectangular tabletop, with the multiple guide rods 50 serving as the tabletop's legs. The lifting mechanism 100 is located at the bottom of the tabletop. This stacked structure design reduces the floor space occupied by the lifting mechanism 100 and facilitates a compact structure.

[0035] Furthermore, the plurality of guide rods 50 are vertically slidably connected to the support plate 31 and are symmetrically distributed, which helps the plurality of guide rods 50 to more stably support the lifting member 30, so that the lifting member 30 can slide up and down stably.

[0036] Furthermore, the support plate 31 is a flat plate with a U-shaped opening 311. The U-shaped opening 311 is disposed toward the lifting drive mechanism 20. When the support plate 31 slides up and down through the lifting mechanism 20, the lifting drive mechanism 20 can be embedded in the U-shaped opening 311. This design ensures that the lifting drive mechanism 20 between the multiple guide rods 50 does not affect the up and down sliding of the support plate 31, that is, the various components of the lifting mechanism 100 are integrated into as small a space as possible.

[0037] Further references Figure 1 and Figure 3 The lifting mechanism 100 also includes two diffuse reflection sensors 60 fixed on the lifting plane 321. The two diffuse reflection sensors 60 are arranged diagonally and are used to detect whether the document 200 to be stamped is placed at a predetermined position on the lifting member 30.

[0038] As can be understood, to use the lifting mechanism 100 to lift the document 200 to be stamped, the document 200 often needs to be placed in a designated position. Random placement facilitates smooth subsequent stamping of the document 200. The document 200 to be stamped is placed on the lifting plane 321 for stamping. The predetermined position can be understood as a designated location suitable for stamping, and can be set so that the document 200 covers the two diffuse reflection sensors 60. The document 200 is often a regular rectangle, and the diagonal spacing between the two diffuse reflection sensors 60 is designed to be the length of the diagonal line of the document 200. When the document 200 to be stamped is not placed in the predetermined position, at least one of the diffuse reflection sensors 60 will generate a switching signal. Only when the document 200 covers both diffuse reflection sensors 60 will the document 200 reflect the light beams emitted by the two diffuse reflection sensors 60, causing both diffuse reflection sensors 60 to generate switching signals, indicating that the document 200 to be stamped has been placed in the predetermined position.

[0039] In this embodiment, the lifting mechanism 100 also includes a photoelectric switch assembly 80 for detecting whether the lifting member 30 has descended to the zero position. The photoelectric switch assembly 80 includes a photoelectric bracket 81 fixedly provided on the support plate 31 and a photoelectric switch 82 fixedly provided on the lifting drive mechanism 20. The photoelectric bracket 81 slides up and down with the lifting member 30. When the lifting member 30 descends to the zero position, the photoelectric bracket 81 is used to reflect the light beam emitted by the photoelectric switch 82.

[0040] The zero position can be understood as the lowest position at which the lifting member 30 slides down along the plurality of guide rods 50. When the lifting member 30 descends to this zero position, the lifting drive mechanism 20 no longer drives the lifting member 30 to descend. When the lifting member 30 descends, when the photoelectric bracket 81 is able to reflect the light beam emitted by the photoelectric switch 82 to the photoelectric switch 82 so that the photoelectric development generates a switch signal, it indicates that the lifting member 30 has descended to the zero position.

[0041] Further references Figure 2 The lifting mechanism 100 also includes at least one anti-slip assembly 70, each of the anti-slip assembly 70 includes a first fixing frame 71 fixedly connected to the support plate 31, a second fixing frame 72 fixedly connected to the lifting platform 32, and a connecting member 73 connecting the first fixing frame 71 and the second fixing frame 72, the second fixing frame 72 is provided with a sliding groove 721 extending along the sliding direction of the lifting member 30, and one end of the connecting member 73 connected to the second fixing frame 72 is slidably connected to the sliding groove 721.

[0042] In this embodiment, due to the elastic effect of the spring 33, the anti-slip assembly 70 is used to connect the support plate 31 and the lifting platform 32. The anti-slip assembly 70 can prevent the lifting platform 32 from separating from the support plate 31 during movement; at the same time, due to the design of the sliding groove 721 extending along the sliding direction of the lifting member 30, the connecting member 73 and the second fixed frame 72 are movably connected, so that relative movement can occur between the support plate 31 and the lifting platform 32; in this way, the anti-slip assembly 70 prevents the lifting platform 32 from separating from the support plate 31 during movement, and also ensures that the spring 33 realizes its elastic effect.

[0043] In one embodiment, the connecting member 73 is a pin.

[0044] Reference Figure 4 The embodiment of the present application also provides a stamping machine 300 using the above-mentioned lifting mechanism, and the stamping machine includes a housing 400 and the lifting mechanism arranged in the housing 400.

[0045] In the stamping machine, the lifting mechanism can effectively and automatically drive the document on the lifting member to slide up and down, and can automatically lift the document to the stamping position, which is conducive to automatic stamping and reduces manual participation in the stamping process.

[0046] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application should be included in the scope of protection of the present application.
