Description

Technical Field

[0001] This invention relates to the field of automatic stamping, and more particularly to a self-identifying stamping machine. Background Technology

[0002] Currently, many places need to use automatic stamping machines. Patent publication document CN204774143U discloses an automatic stamping machine. This type of stamping machine has a problem: after the document to be stamped is placed below the stamp, the stamp is applied directly. Therefore, if the document is placed crookedly, the stamp (relative to the text) on the document will definitely be crooked. So, with this type of stamping machine, the document must be placed upright, otherwise the stamped stamp will definitely be crooked relative to the text. Summary of the Invention

[0003] To address the aforementioned problems, this invention proposes a self-identifying stamping machine.

[0004] The technical solution adopted in this invention is as follows:

[0005] A self-identifying stamping machine includes a support, a longitudinal and transverse moving assembly, a base, a mounting plate, a rotary adjustment motor, a recognition camera, a stamping assembly, and a rotation sensor. The longitudinal and transverse moving assembly is mounted on the support, the base is mounted on the longitudinal and transverse moving assembly, the rotary adjustment motor is mounted on the base, the mounting plate is coupled to the shaft of the rotary adjustment motor, the recognition camera is mounted on the support, and the rotation sensor is mounted on the base. The rotation sensor is used to monitor the amount of rotation of the mounting plate relative to the base. A lead screw is provided on the mounting plate, the stamping assembly is mounted on the moving block of the lead screw, and a support plate is provided on the support, the support plate being located below the stamping assembly.

[0006] The process of this stamping machine is as follows: First, the documents to be stamped (several A4 sheets of paper) are placed on the carrier plate. Then, the recognition camera takes a picture of the carrier plate and obtains the image information of the documents on the carrier plate. From the image information obtained by the recognition camera, the position to be stamped and the orientation of the documents are determined. Then, the longitudinal and transverse moving component moves the base above the stamping position. Then, the rotary adjustment motor starts to rotate, driving the mounting plate to rotate, thereby adjusting the orientation of the stamp on the stamping component on the mounting plate. Once the orientation of the stamp is adjusted to be in place (i.e., the orientation of the text on the stamp is consistent with the orientation of the text on the document), the lead screw rotates and drives the stamping component to move towards the carrier plate, thus completing the entire stamping process.

[0007] In summary, after the stamp is installed, this type of stamping machine can automatically adjust the position and angle of the stamp according to the placement of the document, thereby ensuring that the stamp on the document is not crooked and is accurately positioned.

[0008] In this stamping machine, a rotation sensor is used to monitor the amount of rotation of the mounting plate relative to the base. This allows for real-time monitoring of the stamp's rotation and provides real-time information on the stamp's angular position.

[0009] In this stamping machine, a control host is also provided to coordinate and control the operation of various electronic devices. The rotary adjustment motor, the identification camera, the rotation sensor, the motors on the longitudinal and transverse moving components, the motors on the lead screw, and the motors on the stamping components are all electrically connected to the control host, and the operating status is controlled by the control host.

[0010] In this stamping machine, position monitoring sensors are installed at two positions on the upper and lower parts of the mounting plate in order to monitor the position of the stamping component that moves up and down. When the stamping component passes the position monitoring sensor, it will be triggered by the position monitoring sensor.

[0011] Optionally, the longitudinal and transverse movement assembly includes a transverse motor, a longitudinal motor, a platform, a transverse belt, and a longitudinal belt. The support is provided with a guide rail, the platform is slidably engaged with the guide rail, the transverse belt is rotatably mounted on the support, the transverse motor is used to directly or indirectly drive the transverse belt to rotate, the platform is fixed to the transverse belt, the longitudinal belt is rotatably mounted on the platform, the base is slidably mounted on the platform, and the base is fixed to the longitudinal belt.

[0012] In the above components, when the transverse motor is running, it drives the transverse belt to rotate, and the platform moves relative to the support. When the longitudinal motor is running, it drives the longitudinal belt to move, and the base on the platform moves relative to the platform. The above longitudinal and transverse movement components can enable the base to move relative to the support in a two-dimensional plane, while the rotary adjustment motor can enable the mounting plate to rotate relative to the support in a plane. The rotation of the mounting plate can drive the adjustment of the angle of the adjustment plate.

[0013] Optionally, it also includes two transverse rotating wheels, both of which are rotatably mounted on the bracket. The transverse belt is sleeved on the transverse rotating wheels, and the transverse motor is engaged with the transverse rotating wheels.

[0014] Optionally, the platform is provided with a slide bar, and the base is slidably engaged with the slide bar.

[0015] Optionally, the base is provided with a sliding sleeve, which is slidably engaged with the sliding rod, and the sliding rod is a cylindrical sliding rod.

[0016] Optionally, the longitudinal transfer wheel is rotatably mounted on the platform. There are two longitudinal transfer wheels, the longitudinal transfer belt is sleeved on the longitudinal transfer wheel, and the longitudinal transfer motor is engaged with the longitudinal transfer wheel.

[0017] Optionally, there are two guide rails, and the two guide rails are in a parallel and non-contact state.

[0018] Optionally, the stamping assembly includes a first side plate, a second side plate, a clamp fixing seat, a partition, bolts, and springs. The first side plate and the second side plate are fixed together by the partition and are in a parallel state. The bolts are detachably engaged with the clamp fixing seat and are slidably engaged with through holes on the partition. There are four bolts between the partition and the clamp fixing seat, and each bolt is fitted with a spring. The springs are conical springs, with the wide end of the spring abutting against the partition and the narrow end of the spring abutting against the clamp fixing seat. There are multiple partitions between the first side plate and the second side plate, and each partition is fitted with a clamp fixing seat.

[0019] The function of this stamping assembly is as follows: First, the clamping base is used to clamp the stamp. When stamping, the partition and the clamping base are compressed, reducing the distance between them. The spring between them acts as a buffer and shock absorber. Since the spring in this assembly is a conical spring, with the wide end of the spring abutting against the partition, the conical spring provides a corrective function during the stamping operation, ensuring that there is no misalignment or jamming between the clamping base and the partition.

[0020] Specifically, in this stamping assembly, multiple partitions are provided between the first side plate and the second side plate. Each partition is equipped with a clamp fixing seat by bolts and springs. Each clamp fixing seat can be used to install a stamp, so multiple stamps can be fixed.

[0021] This type of stamping component uses a conical spring, which has good tilt self-adaptation ability, so it has better adaptability when stamping across the seam.

[0022] In summary, this stamping assembly has a conical spring between the clamp fixing seat and the partition, with the narrow end of the frustum-shaped spring abutting against the clamp fixing seat and the wide end of the spring abutting against the partition, ensuring that there is no misalignment or jamming between the clamp fixing seat and the partition.

[0023] Optionally, it also includes a mounting frame, a stamp-changing motor, a stamp-changing wheel, and a stamp-changing belt. A rotating shaft is provided on the first side plate and the second side plate. The two ends of the rotating shaft are respectively engaged with the mounting frame. The stamp-changing motor is mounted on the mounting frame. The stamp-changing wheel is provided on both the mounting frame and the stamp-changing motor. The stamp-changing belt is engaged with the stamp-changing wheel.

[0024] Specifically, the first side plate, the second side plate, and the partition are assembled together to form a stamp frame. Various stamps are installed on the various clamps of the stamp frame. The stamp frame is mounted on the mounting frame by rotating a shaft. When the stamp changing motor rotates, it drives the stamp frame to rotate on the mounting frame, thereby changing the position of each stamp relative to the mounting frame.

[0025] Optionally, it also includes a pressure wheel, which is rotatably mounted on the mounting frame and is in contact with the seal changing belt.

[0026] The function of the pressure roller is to ensure that the seal changing belt is always taut.

[0027] Optionally, the mounting bracket is equipped with an infrared beam sensor.

[0028] Specifically, the first or second side plate can block the light emitted by the infrared beam sensor, which can monitor the position of the frame after rotation by detecting changes in light. A contact piece is specifically provided on the first side plate, which can trigger the infrared beam sensor.

[0029] Optionally, a Hall plate is provided on the mounting bracket, and a magnet is provided on the first side plate.

[0030] The Hall plate and the magnet are used to record the initial position of the frame before it starts to rotate.

[0031] Optionally, six partitions are provided between the first side plate and the second side plate, and the six partitions are distributed in a hexagonal shape.

[0032] Optionally, the partition is perpendicular to the first side plate and the second side plate, and the bolt is perpendicular to the partition and the clamp fixing seat.

[0033] The beneficial effect of this invention is that after the stamp is installed, the position and angle of the stamp can be automatically adjusted according to the placement of the document, thereby ensuring that the stamp on the document is not crooked and is in an accurate position.

Detailed implementation method:

[0043] The present invention will now be described in detail with reference to the accompanying drawings.

[0044] As attached Figure 1 ~Attached Figure 8 As shown, a self-identifying stamping machine includes a support 1, a longitudinal and transverse moving assembly, a base 7, a mounting plate 9, a rotary adjustment motor 8, a recognition camera, a stamping assembly, and a rotation sensor 14. The longitudinal and transverse moving assembly is mounted on the support 1, the base 7 is mounted on the longitudinal and transverse moving assembly, the rotary adjustment motor 8 is mounted on the base 7, and the mounting plate 9 is coupled to the shaft of the rotary adjustment motor 8. The recognition camera 4 is mounted on the support 1, and the rotation sensor 14 is mounted on the base 7. The rotation sensor 14 is used to monitor the amount of rotation of the mounting plate 9 relative to the base 7. A lead screw 16 is provided on the mounting plate 9, and the stamping assembly is mounted on the moving block 1601 of the lead screw 16. A support plate 15 is provided on the support 1, and the support plate 15 is located below the stamping assembly.

[0045] The process of this stamping machine is as follows: First, the documents (several A4 sheets) to be stamped are placed on the carrier plate 15. Then, the recognition camera 4 takes a picture of the carrier plate 15 and obtains the image information of the documents on the carrier plate 15. From the image information obtained by the recognition camera, the position to be stamped and the orientation of the documents are determined. Then, the longitudinal and transverse moving component moves the base 7 above the stamping position. Then, the rotary adjustment motor 8 starts to rotate, driving the mounting plate 9 to rotate, thereby adjusting the orientation of the stamp on the stamping component on the mounting plate 9. Once the orientation of the stamp is adjusted to be in place (i.e., the orientation of the text on the stamp is consistent with the orientation of the text on the document), the lead screw 16 rotates and drives the stamping component to move towards the carrier plate 15, thus completing the entire stamping process.

[0046] In summary, after the stamp is installed, this type of stamping machine can automatically adjust the position and angle of the stamp according to the location of the document, thereby ensuring that the stamp on the document is not crooked and is accurately positioned.

[0047] In this stamping machine, the rotation sensor 14 is used to monitor the amount of rotation of the mounting plate 9 relative to the base 7, so that the rotation of the stamp can be monitored in real time and the angle position of the stamp can be known in real time.

[0048] In this stamping machine, a control host is also provided to coordinate and control the operation of various electronic devices. The rotary adjustment motor 8, the identification camera, the rotation sensor 14, the motors on the longitudinal and transverse moving components, the motors on the lead screw 16, and the motors on the stamping components are all electrically connected to the control host, and the operating status is controlled by the control host.

[0049] In this stamping machine, in order to monitor the position of the stamping component that moves up and down, position monitoring sensors 17 are installed at two positions on the mounting plate 9. When the stamping component passes by the position monitoring sensor 17, it will be triggered by the position monitoring sensor 17.

[0050] As attached Figure 1 ~Attached Figure 8 As shown, the longitudinal and transverse movement assembly includes a transverse motor 11, a longitudinal motor 10, a platform 2, a transverse belt, and a longitudinal belt. A guide rail 3 is provided on the support 1, and the platform 2 is slidably engaged with the guide rail 3. The transverse belt is rotatably mounted on the support 1. The transverse motor 11 is used to directly or indirectly drive the transverse belt to rotate. The platform 2 is fixed together with the transverse belt. The longitudinal belt is rotatably mounted on the platform 2. The base 7 is slidably mounted on the platform 2 and is fixed together with the longitudinal belt.

[0051] In the above components, when the transverse motor 11 is running, it drives the transverse belt to rotate, and the platform 2 moves relative to the support 1. When the longitudinal motor 10 is running, it drives the longitudinal belt to move, and the base 7 on the platform 2 moves relative to the platform 2. The above longitudinal and transverse movement components can enable the base 7 to move relative to the support 1 in a two-dimensional plane, while the rotary adjustment motor 8 can enable the mounting plate 9 to rotate relative to the support 1 in a plane. The rotation of the mounting plate 9 can drive the adjustment of the angle of the adjustment plate.

[0052] As attached Figure 1 ~Attached Figure 8 As shown, it also includes a transverse rotating wheel 12. There are two transverse rotating wheels 12, both of which are rotatably mounted on the bracket 1. A transverse belt is sleeved on the transverse rotating wheel 12, and the transverse motor 11 is engaged with the transverse rotating wheel 12.

[0053] As attached Figure 1 ~Attached Figure 8 As shown, a slide bar 6 is provided on the platform 2, and the base 7 is slidably engaged with the slide bar 6.

[0054] As attached Figure 1 ~Attached Figure 8 As shown, a sliding sleeve is provided on the base 7, and the sliding sleeve is slidably engaged with the sliding rod 6. The sliding rod 6 is a cylindrical sliding rod 6.

[0055] As attached Figure 1 ~Attached Figure 8 As shown, there are two longitudinal transfer wheels 13 rotatably mounted on the platform 2. A longitudinal transfer belt is sleeved on the longitudinal transfer wheel 13, and the longitudinal transfer motor 10 is engaged with the longitudinal transfer wheel 13.

[0056] As attached Figure 1 ~Attached Figure 8 As shown, there are two guide rails 3, and the two guide rails 3 are in a parallel and non-contact state.

[0057] As attached Figure 1 ~Attached Figure 8 As shown, the stamping assembly includes a first side plate 24, a second side plate 25, a clamp fixing seat 26, a partition 27, bolts 29, and springs 28. The first side plate 24 and the second side plate 25 are fixed together by the partition 27 and are in a parallel state. The bolts 29 are detachably engaged with the clamp fixing seat 26 and are slidably engaged with the through holes on the partition 27. There are four bolts 29 between the partition 27 and the clamp fixing seat 26. Each bolt 29 is fitted with a spring 28. The springs 28 are conical springs. The wide end of the spring 28 abuts against the partition 27, and the narrow end of the spring 28 abuts against the clamp fixing seat 26. There are multiple partitions 27 between the first side plate 24 and the second side plate 25, and each partition 27 is engaged with a clamp fixing seat 26.

[0058] The function of this stamping assembly is as follows: First, the clamping base 26 is used to clamp the stamp. When stamping, the partition 27 and the clamping base 26 are compressed, and the distance between them decreases. The spring 28 between them plays a role in buffering and shock absorption. Since the spring 28 in this assembly is a conical spring, the wide diameter end of the spring 28 abuts against the partition 27. During the stamping operation, the conical spring 28 gives the two a corrective function, ensuring that there is no misalignment or jamming between the clamping base 26 and the partition 27.

[0059] In this stamping assembly, multiple partitions 27 are provided between the first side plate 24 and the second side plate 25. Each partition 27 is equipped with a clamp fixing seat 26 by bolts 29 and springs 28. Each clamp fixing seat 26 can be used to install a stamp, so multiple stamps can be fixed.

[0060] This type of stamping assembly uses a conical spring 28, which has good tilt self-adaptation ability, so it has better adaptability when stamping across the seam.

[0061] In summary, this stamping assembly has a conical spring 28 between the clamp fixing seat 26 and the partition plate 27. The narrow diameter end of the frustum-shaped spring 28 abuts against the clamp fixing seat 26, and the wide diameter end of the spring 28 abuts against the partition plate 27, ensuring that there will be no misalignment or jamming between the clamp fixing seat 26 and the partition plate 27.

[0062] As attached Figure 1 ~Attached Figure 8 As shown, it also includes a mounting frame 19, a stamp-changing motor 18, a stamp-changing wheel 20, and a stamp-changing belt 22.

Various stamps are installed on the various clamp fixing seats 26 of the stamp frame. The stamp frame is rotatably mounted on the mounting frame 19 via the rotating shaft 13. When the stamp changing motor 18 rotates, the stamp changing motor 18 drives the stamp frame to rotate on the mounting frame 19, thereby changing the position of each stamp relative to the mounting frame 19.
