Description

Technical Field

[0001] The present invention relates to the technical field of stamping equipment, in particular to a stamping machine with self-adaptation function and a control method of the stamping machine. Background Art

[0002] Manual stamping is slow and inefficient. When stamping large numbers of documents, this increases the workload and can easily lead to errors. Therefore, there is widespread demand for automatic stamping equipment to address this situation. Currently, automatic stamping equipment on the market primarily utilizes two methods: press-type and roller-type. The press-type method is similar to manual stamping, with a motor-driven seal pressing vertically down the paper to affix the stamp. The roller-type method requires a dedicated stamp that rotates during stamping, using a rolling action.

[0003] The existing solution uses a stamping method, which involves two actions: dipping the seal in oil and then stamping. One action is the up-and-down movement of the seal, which uses a rack-and-pinion mechanism, and the other is the transition between the dipping position and the stamping position. The seal is rigidly connected to the frame, and the pressure doesn't adapt to paper thickness, resulting in unclear printing. Summary of the Invention

[0069] The invention provides a stamping machine with a self-adaptive function.

[0070] In the embodiment of the present invention, Figures 1 to 9 As shown, the stamping machine with adaptive function includes a base 1, a frame 2, a controller 3, a driving module 4, a stamp device 5, a positioning laser 6, a paper position sensor assembly, and a stamp position sensor assembly. The base 1 has a stamping position 1a and an ink pad position 1b; the frame 2 is connected to the base 1; the driving module 4 is arranged on the frame 2 and electrically connected to the controller 3; the stamp device 5 is connected to the output end of the driving module 4; the driving module 4 drives the stamp device 5 to move to the ink pad position 1b to dip in oil, and drives the stamp device 5 after dipping in oil to move to the stamping position 1a to perform a stamping operation;

[0071] The seal device 5 includes a seal structure 51, a force sensor 52, a guide post 53 and a compression spring 54; the force sensor 52 is electrically connected to the controller 3; the force sensor 52 is used to detect the magnitude of the force applied to the seal structure 51; one end of the guide post 53 is connected to the output end of the drive module 4, and the other end is movably connected to the seal structure 51; the compression spring 54 is sleeved on the guide post 53, and the two ends of the compression spring 54 are respectively connected to the drive module 4 and the seal structure 51;

[0072] The positioning laser 6 is provided on the frame 2 and is located above the stamping position 1a; the positioning laser 6 is electrically connected to the controller 3;

[0073] The paper position sensor assembly includes a first position detection sensor 71 and a second position detection sensor 72 provided on the base 1. The first position detection sensor 71 and the second position detection sensor 72 are spaced apart along the feeding direction of the paper. The first position detection sensor 71 and the second position detection sensor 72 are used to detect the position of the paper. The first position detection sensor 71 and the second position detection sensor 72 are electrically connected to the controller 3 respectively.

[0074] The seal position sensor assembly includes a third position detection sensor 81 and a fourth position detection sensor 82 provided on the frame 2. The third position detection sensor 81 is used to detect whether the seal device 5 has moved to the ink pad position 1b, and the fourth position detection sensor 82 is used to detect whether the seal device 5 has moved to the stamping position 1a. The third position detection sensor 81 and the fourth position detection sensor 82 are electrically connected to the controller 3 respectively.

[0075] When the first position detection sensor 71 detects that the paper has reached the position above it, the controller 3 controls the positioning laser 6 to emit a laser beam 61 toward the center of the stamping position 1a, so that the center of the paper to be stamped corresponds to the center of the stamping position 1a.

[0076] After the second position detection sensor 72 detects that the paper has reached above it, the controller 3 controls the driving module 4 to drive the seal structure 51 to move toward the ink pad position 1b. After the third position detection sensor 81 detects that the seal structure 51 has reached above the ink pad position 1b, the controller 3 controls the seal structure 51 to move downward to perform the oil dipping operation.

[0077] The control driving module 4 drives the seal structure 51 that has completed the oil dipping operation to move. When the fourth position detection sensor 82 detects that the seal structure 51 has reached the upper part of the stamping position 1a, the control seal structure 51 moves downward to perform the stamping operation.

[0078] When performing a stamping operation, the stamp structure 51 presses the paper downward under the drive of the driving module 4. When the stamp structure 51 is subjected to the reaction force of the paper, the compression spring 54 is compressed upward. When the pressure value detected by the force sensor 52 reaches a preset value, the controller 3 controls the driving module 4 to stop pressing down.

[0079] It is understood that during the stamping operation, when the stamp structure 51 contacts the paper, the compression spring 54 is compressed. The force applied by the stamp structure 51 to the paper is detected by the force sensor 52. When the force sensor 52 reaches a preset value, the stamp structure 51 stops pressing down, thereby achieving a constant stamping pressure regardless of the thickness of the paper. At the same time, the stamping machine achieves the purpose of automatic oil dipping and stamping through the cooperation of the first position detection sensor 71, the second position detection sensor 72, the third position detection sensor 81, and the fourth position detection sensor 82, the drive module 4, and the controller 3, thereby reducing the workload of personnel and improving work efficiency.

[0080] The stamping machine provided by the present invention is self-adaptive to the thickness of paper. No matter what the thickness of the paper is, the force of stamping can be consistent each time through the detection of the force sensor 52 and the control of the driving module 4 by the controller 3.

[0081] At the same time, the automated program control can achieve precise control, so the time and quantity of stamping by the stamping machine of the present invention can be managed and controlled.

[0082] like Figure 9 As shown, the seal structure 51 is connected to a blocking piece 55. When the seal structure 51 presses the compression spring 54 upward, the seal structure 51 drives the blocking piece 55 to move upward to press the force sensor 52, and the force sensor 52 detects the magnitude of the force.

[0083] In one embodiment of the present invention, Figures 1 to 9 As shown, the stamping machine further includes a housing 9, the housing 9 is provided with a receiving cavity, the frame 2 is arranged in the receiving cavity, and a paper inlet 9a for feeding and exiting the paper to be stamped is formed between the housing 9 and the base 1;

[0084] The first position detection sensor 71, the stamping position 1a and the third position detection sensor 81 are arranged close to the paper inlet 9a, and the second position detection sensor 72 is located on the side of the first position detection sensor 71 away from the paper inlet 9a; the first position detection sensor 71 is located between the third position detection sensor 81 and the stamping position 1a, and the stamping position 1a is located between the first position detection sensor 71 and the second position detection sensor 72.

[0085] It is understandable that the housing 9 plays a protective role, and the paper to be stamped can be fed from the paper inlet 9a for stamping by manual or mechanical conveying.

[0086] like Figure 1As shown, the housing 9 is provided with a button 92 and an indicator light 93. A transparent door 91 is provided in the housing 9 corresponding to the paper inlet 9a, which facilitates observation of the oiling and stamping operations inside the housing 9. When manually feeding paper, the alignment of the center of the paper to be stamped with the center of the stamping position 1a can be observed with the naked eye.

[0087] In one embodiment of the present invention, Figures 1 to 9 As shown, the driving module 4 includes a horizontal driving component 41 and a vertical driving component 42. The horizontal driving component 41 includes a horizontal driving motor 411, a horizontal transmission member 412 and a sliding seat 413. The horizontal driving motor 411 is arranged on the frame 2, and the transmission member is arranged at the output end of the horizontal driving motor 411. The sliding seat 413 is arranged on the transmission member. The horizontal driving motor 411 drives the sliding seat 413 to move horizontally through the transmission member; the vertical driving component 42 includes a vertical driving motor 421 and a vertical transmission member 422. The vertical driving motor 421 is arranged on the sliding seat 413, and the vertical transmission member 422 is arranged at the output end of the vertical driving motor 421. The seal structure 51 is connected to the vertical transmission member 422.

[0088] It is understood that the horizontal drive motor 411 drives the sliding seat 413 for horizontal movement via a transmission member. The movement of the sliding seat 413 drives the entire vertical drive assembly 42 for horizontal movement. The vertical drive motor 421 drives the vertical transmission member 422 to cause the seal structure 51 to move vertically. This enables the seal structure 51 to move between the ink pad position 1b and the stamping position 1a, as well as to perform the ink dipping operation in the ink pad position 1b and the stamping operation in the stamping position 1a.

[0089] In one embodiment of the present invention, Figures 1 to 9 As shown, the horizontal transmission member 412 is a synchronous belt structure; the vertical transmission member 422 is a screw structure. It should be noted that the horizontal transmission member 412 and the vertical transmission member 422 can also adopt other transmission structure forms.

[0090] In one embodiment of the present invention, Figures 1 to 9 As shown, the seal structure 51 includes a fixed sleeve 511 and a chapter sleeve assembly 512. The peripheral wall of the fixed sleeve 511 is provided with a positioning groove 511a and a make way channel 511b communicated with the positioning groove 511a. The make way channel 511b extends to one end of the fixed sleeve 511, and the fixed sleeve 511 is connected to the output end of the driving module 4. The chapter sleeve assembly 512 is provided with a positioning pin 513. The chapter sleeve assembly 512 and the fixed sleeve 511 are detachably connected through the cooperation of the positioning pin 513 and the positioning groove 511a.

[0091] In which, the positioning pin 513 slides from the make way channel 511b into the positioning groove 511a to lock the fixing sleeve 511 and the chapter sleeve assembly 512, or the positioning pin 513 slides out from the positioning groove 511a along the make way channel 511b to unlock the fixing sleeve 511 and the chapter sleeve assembly 512.

[0092] It can be understood that, through the cooperation between the positioning groove 511 a and the positioning pin 513 , the chapter cover assembly 512 and the fixed cover 511 can be quickly separated, so that the chapter cover assembly 512 can be easily replaced.

[0093] In one embodiment of the present invention, Figures 6 to 9 As shown, the seal sleeve assembly 512 includes a connecting sleeve 5121 and a seal 5122. The connecting sleeve 5121 is provided with the positioning pin 513. The connecting sleeve 5121 is detachably connected to the fixed sleeve 511 through the cooperation of the positioning pin 513 and the positioning groove 511a; the seal is connected to the side of the connecting sleeve 5121 away from the fixed sleeve 511.

[0094] The connecting sleeve 5121 includes a quick-release part 51211 and a sleeve part 51212. The outer peripheral wall of the quick-release part 51211 is provided with the positioning pin 513, and the quick-release part 51211 is inserted into the fixed sleeve 511; the sleeve part 51212 is connected to the quick-release part 51211, and the sleeve part 51212 abuts against or is spaced apart from the end of the fixed sleeve 511; the sleeve part 51212 is threadedly connected to the seal and is fixed by a bolt 514.

[0095] In one embodiment of the present invention, Figures 6 to 9 As shown, the seal sleeve assembly 512 includes a quick-release part 51211, a sleeve part 51212 and a seal. The outer peripheral wall of the quick-release part 51211 is provided with the positioning pin 513, and the quick-release part 51211 is inserted into the fixed sleeve 511; the sleeve part 51212 is connected to the quick-release part 51211, and the sleeve part 51212 is abutted against or spaced apart from the end of the fixed sleeve 511; the sleeve part 51212 is threadedly connected to the seal and fixed by a bolt 514; the sleeve part 51212 is threadedly connected to the seal and fixed by a bolt 514.

[0096] An anti-slip portion 512121 is provided on the outer wall of the sleeve portion 51212 , which facilitates operation during installation and disassembly.

[0097] The end of the seal away from the connecting sleeve 5121 has a seal portion, and the end of the seal away from the seal portion is threadedly connected to the sleeve portion 51212 and fixed by a bolt 514; the axial direction of the bolt 514 is parallel to the axial direction of the sleeve portion 51212.

[0098] like Figures 6 to 9 As shown, the seal further includes an adjusting button 515. In this embodiment, the axis direction of the adjusting button 515 is perpendicular to the axis direction of the positioning pin 513.

[0099] In one embodiment of the present invention, Figures 6 to 9 As shown, the quick-release portion 51211 is provided with a positioning hole 51211 a , and the fixing sleeve 511 is provided with a bumper 5111 , and the bumper 5111 is adapted to the positioning hole 51211 a .

[0100] It can be understood that the positioning of the fixing sleeve 511 and the chapter sleeve assembly 512 can be achieved through the cooperation between the bumper 5111 and the positioning hole 51211a.

[0101] In one embodiment of the present invention, Figure 6 and Figure 7 As shown, the positioning groove 511a extends along the circumferential direction of the fixing sleeve 511, and the clearance channel 511b extends along the axial direction of the fixing sleeve 511, so that the positioning groove 511a and the clearance channel 511b are connected to form an L-shaped structure.

[0102] In one embodiment of the present invention, Figures 6 to 9 As shown, a side wall of the positioning groove 511a close to the chapter cover assembly 512 is defined as a positioning side wall 5112, and the positioning side wall 5112 has an arc-shaped concave positioning groove 5112a, and the positioning groove 5112a cooperates with the positioning pin 513. A side surface of the cavity wall of the yield channel 511b close to the positioning side wall 5112 is defined as a sliding wall surface 5113, and the sliding wall surface 5113 is an arc-shaped surface, and there is a smooth transition from the sliding wall surface 5113 to the positioning groove 5112a. It can be understood that the design of the positioning groove 5112a plays a limiting role on the positioning pin 513. The arc-shaped surface of the sliding wall surface 5113 can facilitate the sliding in and out of the positioning pin 513.

[0103] The present invention also provides a control method for a stamping machine, comprising the following steps:

[0104] After receiving the detection information from the first position detection sensor 71, the positioning laser 6 is controlled to emit a laser beam toward the center of the stamping position 1a;

[0105] After receiving the detection information from the second position detection sensor 72, the driving module 4 is controlled to work, so as to drive the seal structure 51 to move horizontally toward the ink pad position 1b;

[0106] After receiving the detection information from the third position detection sensor 81, the driving module 4 is controlled to drive the seal structure 51 to move vertically downward toward the ink pad position 1b to perform the oil dipping operation. After the oil dipping operation is completed, the driving module 4 drives the seal structure 51 to move vertically upward.

[0107] Control the driving module 4 to drive the seal structure 51 to move horizontally toward the stamping position 1a;

[0108] After receiving the detection information from the fourth position detection sensor 82, the driving module 4 is controlled to work to drive the seal structure 51 to move vertically downward toward the stamping position 1a;
