Description

Technical Field

[0001] This invention relates to the field of electromechanical technology, and in particular to an automatic stamping device. Background Technology

[0002] As labor costs gradually increase, labor-intensive industries are increasingly being replaced by automated tools, thereby improving work efficiency and reducing labor costs. However, in some specialized departments or industries within enterprises, due to the complex nature of their work—such as corporate compliance departments or banking systems—a large number of highly skilled personnel are needed, while simultaneously handling some simple, repetitive tasks, such as stamping. Especially when the volume of stamps is high, this stamping work consumes a significant amount of employee time, hindering the efficiency of specialized personnel and potentially leading to a severe imbalance between company personnel costs and performance output. Therefore, specialized automated stamping tools are required for stamping operations.

[0003] Currently available stamping tools lack automation and cannot meet the needs of different types of stamping. Stamping equipment can only be equipped with one type of stamp and cannot change the stamp in time according to the stamping needs, resulting in time-consuming and complicated stamp disassembly and other problems, which is not conducive to improving work efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide an automatic stamping device to address the problems of low automation performance and inconvenience in stamp replacement.

[0005] An automatic stamping device includes a channel assembly comprising an upper channel assembly and a lower channel assembly, forming a conveying channel between the upper and lower channel assemblies; a stamping assembly disposed on the upper channel assembly, the stamping assembly including a stamp assembly and a drive assembly, the stamp assembly including a stamp head and a stamp head spring, the stamp head being pressed against the conveying channel by the stamp head spring, the drive assembly including a cam and a driver, the driver driving the cam to rotate, the cam rotating to move the stamp head away from the conveying channel; and a stamp changing assembly detachably connected to the stamp head, the stamp head being disposed at the end of the stamp assembly.

[0006] Furthermore, the stamp assembly also includes a stamp fixing seat and a stamp hook. The stamp fixing seat is movably disposed in the upper channel assembly, the stamp hook is disposed on the stamp fixing seat, and the stamp head is connected to the stamp hook.

[0007] Furthermore, the stamp head includes a stamp back seat and a sliding buckle. The sliding buckle is disposed in the stamp back seat and extends or retracts from the stamp back seat in the radial direction. The stamp hook connects to the sliding buckle.

[0008] Furthermore, the outer wall of the seal seat is provided with a seal head protrusion in the circumferential direction. The seal head protrusion is disposed between the sliding buckle and the seal hook, and the seal head protrusion is used to unload the seal head.

[0009] Furthermore, the stamp replacement assembly includes a stamp-retrieving outer cover, the inner wall of which is provided with a stamp head slot and a sliding buckle slot. The stamp head slot engages with the stamp head protrusion, and the sliding buckle slot abuts against the sliding buckle so that the sliding buckle retracts into the stamp seat.

[0010] Furthermore, the stamp head slot and the sliding buckle slot are arranged parallel to each other, and both the stamp head slot and the sliding buckle slot have an opening on the same side end.

[0011] Furthermore, the upper channel assembly is provided with a movable hole for the stamp assembly, and a stamp limiting groove is provided on the inner wall of the movable hole for the stamp assembly. The stamp limiting groove is provided along the axial direction of the movable hole for the stamp assembly, and a stamp guide boss is provided circumferentially on the stamp fixing seat. The stamp guide boss is connected to the stamp limiting groove.

[0012] Furthermore, the upper channel assembly and the lower channel assembly are rotatably connected on one side, a snap-fit ​​shaft is provided on the other side of the upper channel assembly, a snap-fit ​​fixing position is provided on the other side of the lower channel assembly, and the snap-fit ​​shaft is movably connected to the snap-fit ​​fixing position.

[0013] Furthermore, the channel assembly also includes conveyor wheels, which are disposed on both sides of the conveying channel and move to transport materials on the conveying channel.

[0014] Furthermore, it also includes a control system connected to the stamping assembly. The control system includes a detection plate and a sensor. The detection plate moves synchronously with the cam. The detection plate triggers the sensor to send a stop signal to the control system, and the control system controls the driver to stop rotating.

[0015] The automatic stamping device provided in this application consists of a channel assembly, a stamping assembly, and a stamp-changing assembly. The channel assembly has a conveyor channel for transporting papers, documents, etc., that require stamping. The stamping assembly is mounted on the channel assembly and can move closer to or away from the conveyor channel. The stamping assembly includes a stamp component and a drive assembly. The stamp component is pressed against the conveyor assembly, and its end has a stamp head. The stamp head directly presses the stamp onto the paper or document. The drive assembly drives the stamp component away from the conveyor assembly, thereby releasing the paper or document, which is then transported out on the conveyor channel. The stamp-changing assembly is detachably connected to the stamp head, allowing for quick removal and replacement of the stamp head from the stamp assembly. This automatic stamping device with this structure can achieve multiple functions, including rapid stamping and stamp changing, significantly improving work efficiency and reducing labor costs.

Therefore, they should not be construed as limitations on this invention.

[0033] 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 technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0034] In this invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly.

[0037] Figure 1 This invention illustrates the working principle of an automatic stamping device according to an embodiment of the present application, wherein... Figure 1 A represents the first state diagram, i.e., the stamped state. Figure 1B represents the second state diagram, i.e., the paper conveying state. The automatic stamping device provided in this application consists of a channel assembly 10, a stamping assembly 20, and a stamp changing assembly (not shown). The channel assembly 10 is composed of an upper channel assembly 11 and a lower channel assembly 12, which are rotatably connected. When the upper channel assembly 11 and the lower channel assembly 12 are engaged together, a transmission channel 13 is formed between them. The transmission channel 13 is used to place the paper 40 to be stamped.

[0038] The stamping assembly 20 is mounted on the upper channel assembly 11. The stamping assembly 20 includes a stamp assembly 21 and a drive assembly 22. The end of the stamp assembly 21 is provided with a stamp head 211. Normally, the stamp head 211 is in a raised state. The upper channel assembly 11 and the lower channel assembly 12 are engaged together. When the paper 40 reaches the stamping position, the drive assembly 22 drives the cam (not shown) to rotate. The stamp head 211 moves downward under the action of the stamp head spring 2114. When the stamp head 211 contacts the paper 40, the stamp head spring 2114 provides a stable pressure to the stamp head 211, thereby clearly imprinting the stamp on the paper 40.

[0039] The channel assembly 10 also includes conveyor wheels, including an upper channel assembly conveyor wheel 113 disposed on the upper channel assembly 11 and a lower channel assembly conveyor wheel 122 disposed on the lower channel assembly 12. The upper channel assembly conveyor wheel 113 and the lower channel assembly conveyor wheel 122 are respectively located on both sides of the conveying channel 13. The conveyor wheels (113, 122) roll to transport materials on the conveying channel 13. When the stamp assembly 21 moves away from the conveying channel 13 to release the paper 40, the paper 40 is output from the automatic stamping device under the action of the conveyor wheels (113, 122) on both sides of the conveying channel 13, thereby making room for the stamping action of the next paper.

[0040] Furthermore, the automatic stamping device provided in this application is suitable for multiple consecutive stamping actions. The operator needs to set the working cycle of the drive component to control the rotation cycle of the cam, and at the same time set the rolling cycle of the roller, so as to continuously achieve the working state of stamping and paper feeding.

[0041] Figure 2 This illustration shows a perspective view of an automatic stamping device in operation according to an embodiment of this application. Figure 3 A perspective view of the upper channel assembly of an automatic stamping device according to an embodiment of this application is shown. Figure 4 A perspective view of the lower channel assembly of an automatic stamping device according to an embodiment of this application is shown, in conjunction with... Figures 2-4As shown, the automatic stamping device provided in this application includes a channel assembly 10, a stamping assembly 20, and a stamp changing assembly 30. The channel assembly 10 consists of an upper channel assembly 11 and a lower channel assembly 12. The stamping assembly 20 is disposed on the upper channel assembly 11, and the stamp changing assembly 30 is integrated on the stamping assembly 20. The upper channel assembly 11 and the lower channel assembly 12 are rotatably connected on one side by a rotating shaft 14, forming a conveying channel 13 for conveying paper 40 between them.

[0042] Furthermore, the upper channel assembly 11 is provided with a stamp assembly movable hole 111 for placing the stamp assembly 21. The stamp assembly movable hole 111 is connected to the conveying channel 13, facilitating the stamp head 211 to act on the conveying channel 13. Multiple stamp limiting grooves 1111 are provided on the inner wall of the stamp assembly movable hole 111 along its axial direction. The stamp limiting grooves 1111 are used to engage the stamp assembly 21 and restrict the degree of freedom of the stamp assembly 21, thereby ensuring that the stamp assembly 21 can move in a direction perpendicular to the conveying channel 13 without rotating during movement, thus affecting the stamping effect.

[0043] Furthermore, a snap-fit ​​shaft 112 is provided on the other side of the upper channel assembly 11, and a snap-fit ​​fixing position 121 is provided on the other side of the lower channel assembly 12. A movable connection is formed between the snap-fit ​​shaft 112 and the snap-fit ​​fixing position 121, thereby assembling the upper channel assembly 11 and the lower channel assembly 12 together and ensuring the stability of the equipment during operation.

[0044] Furthermore, the upper channel assembly 11 is also provided with a buckle handle 114, which is connected to the buckle shaft 112. By pulling the buckle handle 114, the buckle shaft 112 is moved away from the buckle fixing position 121, thereby facilitating the opening of the upper channel assembly 11.

[0045] Furthermore, the snap-fit ​​fixing position 121 has an inclined surface 1211 on the side facing the upper channel assembly 11. The inclined surface 1211 is inclined away from the snap-fit ​​shaft 112. When the upper channel assembly 11 rotates to snap onto the lower channel assembly 12, the inclined surface on the snap-fit ​​fixing position 121 can facilitate the snap-fit ​​shaft 112 to slide down and snap onto the snap-fit ​​fixing position 121. At the same time, when the snap-fit ​​handle 114 is pulled to move the snap-fit ​​shaft 112 away from the snap-fit ​​fixing position 121 and the upper channel assembly 11 is reversed, the snap-fit ​​fixing position 121 will not restrict the movement of the snap-fit ​​shaft 112.

[0046] Figure 5 A perspective view of the stamping component of an automatic stamping device according to an embodiment of this application is shown. Figure 6 An exploded view of the stamping component of an automatic stamping device according to an embodiment of this application is shown, in conjunction with... Figure 5 , Figure 6As shown, the stamping assembly 20 provided in this application includes a stamp assembly 21 and a drive assembly 22. The drive assembly 22 is used to drive the stamp assembly 21 to lift and release the stamped paper 40. Further, the drive assembly 22 includes a cam 221, a driver 222, and a camshaft 223. A transmission system 224 is provided between the driver 222 and the cam 221. The transmission system 224 includes, but is not limited to, a gear set. The driver 222 drives the cam 221 to rotate via the transmission system 224. The stamp assembly 21 includes a stamp holder 214, and the drive assembly 22 moves the stamp 21 via the stamp holder 214. Figure 1 As shown, cam 221 is fixed on camshaft 223. When cam 221 rotates, when the outermost edge of cam 221 abuts against stamp holder 214, stamp holder 214 is lifted to drive stamp head 211 away from conveyor channel 13.

[0047] Furthermore, this application also includes a control system connected to the stamping assembly 20. The control system includes a detection plate 23 and a sensor 24. The detection plate 23 is mounted on the camshaft 223 and rotates synchronously with the cam 221. The sensor 24 is fixedly connected. During the rotation of the detection plate 23, the sensor 24 is intermittently triggered. After the sensor 24 is triggered, it sends a signal to the control system. The control system controls the operation of the driver 222 by receiving the signal. Optionally, when the user issues a stamping command, the detection piece 23 rotates together with the cam 221. In the initial state, the detection piece 23 is in the position of blocking the sensor 24. At this time, the cam 221 lifts the stamp assembly 21, and the paper 40 to be stamped is transported to the bottom of the stamp assembly 21. During the rotation, the detection piece 23 rotates from the blocked state to the unblocked state, and then rotates back to the state of blocking the sensor 24. At this time, the cam 221 has rotated one revolution, and the sensor 24 sends a stop signal to the control system. The control system controls the driver 222 to stop rotating. At this time, the stamp head 211 protrudes from the upper channel assembly 11 under the action of the stamp head spring 2114 and acts on the paper 40, thereby realizing the stamping. After the stamping is completed, the cam 221 rotates to lift the stamp head 211, so that the stamp head 211 returns to the initial state.

[0048] Furthermore, the stamp-changing component 30 is integrated into the stamping component 20. The stamp-changing component 30 includes a stamp-retrieving cover 31 and a stamp-retrieving latch 32, with the stamp-retrieving cover 31 fixedly connected via the stamp-retrieving latch 32. The stamp-retrieving cover 31 is used for quick disassembly of the stamping component 21; therefore, its specific structure will be described in detail below in conjunction with the structure of the stamping component 21. It should be noted that integrating the stamp-changing component 30 with the stamping component 20 is merely for the convenience of operators. The stamp-changing component 30 can also be set separately from the stamping component 20, or integrated with the channel component 10. Those skilled in the art can make reasonable designs according to actual needs.

[0049] Figure 7 A perspective view of the stamp assembly of an automatic stamping device according to an embodiment of this application is shown. Figure 8 An exploded view of the stamp head of an automatic stamping device according to an embodiment of this application is shown. The stamp assembly 21 includes a stamp head 211, a stamp fixing seat 212, and a stamp hook 213. The stamp fixing seat 212 is movably disposed in the upper channel assembly 11, and the stamp hook 213 is disposed on the stamp fixing seat 212. The stamp head 211 is connected to the stamp hook 213. Figure 3 As shown, a stamp limiting groove 1111 is provided on the inner wall of the movable hole 111 of the stamp assembly along its axial direction. A stamp guide boss 2121 is provided circumferentially on the stamp fixing seat 212. The stamp guide boss 2121 is connected to the stamp limiting groove 1111. The longitudinal movement of the stamp assembly 21 is limited by the cooperation between the stamp guide boss 2121 and the stamp limiting groove 1111.

[0050] Furthermore, the stamp head 211 includes a stamp back seat 2111 and a sliding buckle 2112. Optionally, the sliding buckles 2112 are arranged in pairs inside the stamp back seat 2111 and extend or retract into the stamp back seat 2111 in the radial direction of the stamp back seat 2111. The stamp hook 213 connects to the stamp head 211 by connecting with the sliding buckle 2112.

[0051] Figure 9 This invention illustrates the working principle of the stamp component of an automatic stamping device according to an embodiment of this application, in conjunction with... Figure 7 , Figure 8 As shown, a sliding buckle spring 2115 is provided between the paired sliding buckles 2112. The sliding buckle spring 2115 ensures that one end of the sliding buckle 2112 extends out of the stamp back seat 2111. At this time, the inner wall of the sliding buckle 2112 is provided with a sliding protrusion 2116. The sliding protrusion 2116 is hooked onto the stamp hook 213 under the action of the sliding buckle spring 2115, realizing the connection of the stamp head 211. Figure 9 As shown in Figure A; when it is necessary to disassemble the stamp head 211, push the sliding buckle 2112 to extend one end of the stamp back seat 2111, causing it to retract into the stamp back seat 2111. At this time, the sliding protrusion 2116 disengages from the stamp hook 213, thus facilitating the disassembly of the stamp head 211. Figure 9 As shown in B.

[0052] In summary, when disassembling the stamp head 211, the outer cover 31 needs to push the end of the sliding buckle 2112 to retract into the stamp back seat 2111, thereby disengaging the stamp head 211 from the stamp hook 213. When the outer cover 31 is inserted into the stamp head 211, rotating the outer cover 31 engages the stamp head slot 311 with the stamp head protrusion 2113, at which point the outer cover 31 and the stamp head 211 are fastened together. Simultaneously, when the outer cover 31 is inserted into the stamp head 211, rotating the outer cover 31 causes the sliding buckle slot 312 to abut against the sliding buckle 2112, causing the end of the sliding buckle 2112 to retract into the stamp back seat 2111, i.e., the sliding protrusion 2116 disengages from the stamp hook 213. At this point, removing the outer cover 31 will also remove the stamp head 211, thus completing the stamp removal action.

[0053] Figure 10 This illustration shows a perspective view of the outer cover of an automatic stamping device according to an embodiment of this application. The inner wall of the outer cover 31 is provided with a stamp head slot 311 and a sliding buckle slot 312. The stamp head slot 311 engages with a stamp head protrusion 2113, and the sliding buckle slot 312 abuts against a sliding buckle 2112 so that the end of the sliding buckle 2112 retracts into the stamp back seat 2111. The stamp head slot 311 and the sliding buckle slot 312 are arranged parallel to each other. Both the stamp head slot 311 and the sliding buckle slot 312 have openings on the same side, and the other end of the stamp head slot 311 is a blind end. Furthermore, to facilitate the engagement of the stamp head slot 311 with the stamp head protrusion 2113 and the sliding buckle slot 312 abutting against the sliding buckle 2112, the openings of both the stamp head slot 311 and the sliding buckle slot 312 are beveled.

[0054] Figure 11 This diagram illustrates the working principle of the automatic stamping device according to an embodiment of this application, specifically the outer cover for stamp collection. Figure 9 , Figure 10 As described above, when the outer cover 31 is fastened to the stamp head 211, rotating the outer cover 31 causes the stamp head slot 311 to rotate to the stamp head protrusion 2113, at which point the sliding buckle slot 312 is exactly at the sliding buckle 2112. Continuing to rotate the outer cover 31, since both the stamp head slot 311 and the sliding buckle slot 312 have beveled openings on one side, the stamp head protrusion 2113 and the sliding buckle 2112 can slide into the corresponding slots, thus combining the outer cover 31 and the stamp head 211. This method enables quick disassembly and replacement of the stamp head, expanding the product's application scope and improving the user experience.

[0055] The automatic stamping device provided in this application consists of a channel assembly, a stamping assembly, and a stamp-changing assembly. The channel assembly has a conveyor channel for transporting papers, documents, etc., that require stamping. The stamping assembly is mounted on the channel assembly and can move closer to or away from the conveyor channel. The stamping assembly includes a stamp component and a drive assembly. The stamp component is pressed against the conveyor assembly, and its end has a stamp head. The stamp head directly presses the stamp onto the paper or document. The drive assembly drives the stamp component away from the conveyor assembly, thereby releasing the paper or document. The released paper or document is then conveyed out on the conveyor channel. The stamp-changing assembly is detachably connected to the stamp head, allowing for quick removal of the stamp head from the stamp assembly for better processing. This automatic stamping device with this structure can achieve multiple functions, including rapid stamping and stamp changing, significantly improving work efficiency and reducing labor costs.
