In addition, in the following description, specific details are provided to facilitate a thorough understanding of the examples. However, it will be understood by those skilled in the art that the aspects may be practiced without these specific details.

First, referring to fig. 1, a page separation method according to an embodiment of the present application for separating a first scan object from a second scan object by an angle is described. In particular, for a book, the first scan object may be a page that currently needs to be flipped, and the second scan object may be a subsequent page.

Furthermore, the scanning object may be, for example, a carrier on which information is recorded, such as a book, a newspaper, a ticket, or the like, and may also contain other forms of objects that can be scanned. In the following description, a book is described as an example, and paper, pages, and the like appearing therein are examples of an object to be scanned.

In addition, in the embodiment of the present application, the first scanning object is rotatable about the first rotation axis with respect to the second scanning object. Specifically, in the case of a book, the current page and the following page may rotate around the spine of the book itself, or in the case where the pages are held, the current page and the following page may rotate around the holding portion. During the paging process, it is necessary to rotate the current page around the rotation axis to separate from the following page. That is, the method in the embodiments of the present application is particularly useful for scanning objects that are in or are held in a book.

As shown in fig. 1, in the embodiment of the present application, in order to improve the success rate of paging to improve the scanning efficiency, the page splitting method includes:

s100: and applying a first force to the first scanning object and driving the first scanning object to move a first distance in the direction of the first force, wherein the direction of the first force is intersected with the plane of the first scanning object, and the direction of the first force is towards the first rotating shaft.

Specifically, in separating a current first scan object and a subsequent second scan object, a force is first applied to the first scan object, so that the current scan object is moved by the applied force. The applied force may be provided, for example, by the suction force of the suction cup, thereby pulling the current scanning object to move.

Furthermore, in order to separate the first and second scan objects, a force is applied in a direction towards the first rotational axis of the first and second scan objects, and in order to achieve a better separation, instead of conventionally rotating the first scan object directly around the first rotational axis, in the present embodiment the direction of the applied force intersects the plane in which the first scan object (second scan object) lies.

As shown in fig. 2, it is particularly advantageous to make the direction of the applied force intersect the plane of the first scanning object and move the first distance L in the direction of the first force, because the distance L can be decomposed into a displacement L1 along the direction of the rotation axis and a displacement L2 in the lifting direction, wherein the displacement L1 makes the first scanning object and the second scanning object generate sliding friction, i.e., rubbing, so that the absorption force between the first scanning object and the second scanning object is more easily overcome, and in addition, the displacement L2 makes the first scanning object and the second scanning object separate, so that the first scanning object and the second scanning object are less likely to continue to stick together due to the sliding friction, and the first scanning object and the second scanning object generate a distance due to the separation in the vertical direction, so that they are more easily separated.

That is, unlike the conventional scheme of directly separating around the rotation shaft, in the embodiment of the present application, the current page and the following page are twisted, thereby increasing the success rate of separation. Through experimental verification, more than 80% of the pages stuck together can be separated by rubbing.

In the disclosed embodiment, the angle between the direction of the first force and the plane of the first scanning object may be 40 ° to 50 °, and is preferably 45 °, because 45 ° not only can ensure the distance separating the first scanning object and the second scanning object, but also can ensure the effectiveness of sliding friction (rubbing) between the first scanning object and the second scanning object. If the angle is too large, the friction force is too small, which may result in poor separation effect, and if the angle is too small, the rubbing effect is too large, which may damage the scanning object.

S200: rotating the first scanning object around a second axis of rotation, wherein the position of application of the first force is at a greater distance from the first axis of rotation than the second axis of rotation.

In an actual operation process, even if the current first page and the subsequent page are separated by the rubbing, there may be a case where the current first page and the subsequent page are stuck together, and in this case, it is necessary to separate the first scanning object and the second scanning object by bending the current first scanning object.

Specifically, since a force acts on the current first page, the current first scan object can be bent at a smaller bending radius by using the principle that the bending radius of the page is small and the bounce force is large, so that the bending force of the second scan object is greater than the adsorption force between the first scan object and the second scan object, and the first scan object and the second scan object are separated.

That is, after the rubbing is performed, the first scan object is rotated around the second rotation axis having a smaller radius of rotation to separate the two. In this case, the position of application of the first force is located at a greater distance from the first axis of rotation than the second axis of rotation, i.e., the second axis of rotation is located closer to the outside of the scanning object, i.e., closer to the position of application of the first force, so that a smaller bending radius can be provided. In this manner, compared with a case where the current first scanning object and the subsequent second scanning object are bent directly at the first rotation axis, since a bending force is provided to the subsequent second scanning object, the two objects tend to be separated.

Preferably, the distance between the second rotating shafts needs to be as small as possible, so that a larger bounce force can be provided for the second scanning object which is likely to be stuck during the bending process, but in the actual operation process, the too small bending radius may cause the current first scanning object not to be adsorbed, so that more than 95% of the stuck paper can be separated by generally setting the bending radius of the book paper to be 2cm-5 cm.

As shown in fig. 3, in a specific implementation manner of the embodiment of the present disclosure, after the step S200 of rotating the first scan object around the second rotation axis, the method further includes:

s300: applying a second force to the first scanned object and moving the first scanned object a second distance in a direction of the second force, wherein the second force intersects the plane of the first scanned object with a force, and the direction of the second force is towards the first axis of rotation.

Specifically, after the rubbing and bending operations, in order to image the first scan object and the second scan object, further force needs to be applied to the first scan object and the second scan object, so that the current first scan object and the current second scan object are not in an excessively curved state, thereby facilitating subsequent imaging and flattening. Thus, the already separated first and second scan objects may be further separated by a further force, which in the present embodiment may be directed in the same direction as the square of the first force, e.g. at 45 ° to the plane of the scan object and towards the first axis of rotation.

Preferably, in an embodiment of the application, the first scan object is just in a straightened state after being moved the second distance in the direction of the second force. In this regard, different values of the first distance and the second distance may be set for different sizes of paper so that the paper is just in a straightened state after moving the second distance.

For example, for a sheet of a4 size, a first distance of 5cm and a second distance of 8cm can be used to allow a sheet of a4 size to be just straightened. The moving distance of paper with other sizes can be obtained through experiments, so that the moving distance can be determined without additional detection.

Alternatively, the value of the second distance may be determined by a sensor, and specifically, for example, a photosensitive sensor may be provided at a suction cup that applies a force to the current first scanning object, and after the current first scanning object is moved by the first distance and the second distance by being sucked, after the paper is straightened, if the pulling is continued, the suction cup and the paper may slip relatively until the provided photosensitive sensor leaks out, and the paper may be judged to have been straightened by the triggering of the photosensitive sensor.

In the above, only two methods for determining the value of the second distance are listed, and it should be understood that the value of the second distance may be determined in other manners.

Referring to fig. 4, according to a specific implementation manner of the embodiment of the present disclosure, after the step of applying the second force to the first scanned object and moving the first scanned object by the second distance in the direction of the second force, that is, after determining that the current first scanned object is straightened, the method further includes a step S400 of detecting whether the scanned object applied with the second force is a single page in the step S400.

In the actual operation, even after the rubbing and bending operations as described above, there may be a case where a small portion of the sheets are stuck together, in which case, in order to avoid the image forming process being incomplete and the like occurring later, in the embodiment of the present disclosure, the step of single-double page detection is provided. Specifically, whether the sheet is a single page or not can be detected by, for example, an ultrasonic sensor because an ultrasonic signal is attenuated and reflected in the case where there are a plurality of pages, and whether it is a single page or not can be determined by detecting the attenuation or reflection.

In this case, in case that it is detected that the scan object applied with the second force is a single page, at least one side of the first scan object and/or the second scan object may be imaged. Specifically, at least one of the front side of the first scanning object, the back side of the first scanning object, the front side of the second scanning object, and the back side of the second scanning object may be imaged.

In contrast, in the case where it is detected that the scan object applied with the second force is a non-single page, an additional paging operation for making the scan object applied with the second force into a single page needs to be performed on the scan object applied with the second force. Specifically, the additional sorting operation may be, for example, performing a bending operation again, sucking a subsequent sheet from the other side by an additional sorting device, or blowing air to the sucked scanning object by an air blowing device to separate the stuck sheets.

In a specific implementation manner of the embodiment of the present disclosure, it may be detected whether the current scanning object is a single page after the current first scanning object is rotated around the second rotation axis instead of detecting whether the paper is a single page after the paper is straightened. In this case, the detection can still be performed using an ultrasonic sensor. The single-page and double-page detection operation is carried out after the bending operation, and the condition of multiple pages can be avoided in the early stage, so that an extra paging device is avoided being installed, the operation complexity of paging can be reduced, and the paging efficiency is improved. That is, the positions may be exchanged for steps S300 and S400 shown in fig. 4, thereby making the paging efficiency higher.

In the actual paging, page turning operation, for example, in the case where a plurality of sheets are present, after the current first scanning object and the subsequent second scanning object are separated by bending, there may be a case where the second scanning object is bent due to bending, or the second scanning object cannot be smoothly pressed due to warping occurring due to the paper itself, and in this case, if the image forming operation is directly performed, the image forming effect may be poor. Therefore, as shown in fig. 5, in the embodiment of the present application, after separating the current first scanning object and the subsequent second scanning object by bending, step S500 is further added, and in step S500, the first scanning object is moved in the direction opposite to the direction of the first force, so that by moving the current first scanning object in the opposite direction, the second scanning object which may be bent can also be flattened, so as to facilitate the subsequent imaging. More specifically, the second scan object may be pressed by the pressing block after the current first scan object and the second scan object are moved in opposite directions, which can make the second scan object more flat.

Preferably, in the embodiment of the present application, in the case where the presence of a plurality of pages is detected by single-double page detection, the current first scanning object is moved in the opposite direction, and the number of return presses can be reduced compared to moving in the opposite direction each time, thereby improving the scanning efficiency.

In a specific implementation manner of the embodiment of the present disclosure, for a paper with a relatively large hardness, direct bending may not be performed, and therefore, in this case, while the first scanning object is rotated around the second rotation axis, the first scanning object and the second scanning object may also be moved toward the direction of the first rotation axis, and by performing the bending operation and the horizontal moving operation as in the embodiment of the present disclosure, paging of the paper with a relatively large hardness can be facilitated, because by performing the bending operation and the horizontal moving operation at the same time, the bending degree of the paper with a relatively large hardness can be reduced, thereby avoiding the possibility of failure in adsorbing the current first scanning object.

Alternatively, the first and second scan subjects may be first moved toward the direction of the first rotation axis and then moved in the direction opposite to the direction of the first rotation axis while rotating the first scan subject around a second rotation axis.

By such reciprocating operation, the operation of turning the pages is coordinated with the movement of the scanning object, the situation that the harder paper falls due to bending can be prevented, and in addition, the final staying position of the scanning object such as a book can be fixed, thereby facilitating the subsequent imaging, because it is not necessary to further adjust the position of the camera.

Furthermore, by adding the pulling of the second force by the back motion, the current first scan object can be quickly brought into a straightened state, thereby improving the efficiency of the whole scan.

In the above, some of the embodiments of the present application are described, but it should be understood that the embodiments of the present application are not limited thereto.

In addition, fig. 6 shows a page separation apparatus 600 for separating a first scan object from a second scan object by an angle, wherein the first scan object is rotatable relative to the second scan object about a first rotation axis, the apparatus 600 comprising:
