All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present disclosure should fall within the scope of protection of the embodiments in the present disclosure.

According to a first aspect of embodiments of the present disclosure, referring to fig. 1-5, embodiments of the present disclosure provide a sheet cutting system comprising: a cutting part 10, a transporting part 20, and a stage 30, the cutting part 10 and the transporting part 20 being disposed on the stage 30; the transportation part 20 comprises a conveying unit 21 and a first driving unit 22, wherein the conveying unit 21 is used for conveying a raw material plate, and the first driving unit 22 is connected with the conveying unit 21 and is used for driving the conveying unit 21 to move so that the conveying unit 21 drives the raw material plate to move along a first track when the raw material plate is arranged on the conveying unit 21; the cutting part 10 comprises a laser cutting knife 11 and a second driving unit 12, the second driving unit 12 is connected with the laser cutting knife 11, the laser cutting knife 11 is located above the conveying unit 21, and the second driving unit 12 is set to drive the laser cutting knife 11 to move along a second track based on the first track and a preset shape so as to cut the plate with the preset shape from the plate raw material.

In the plate cutting system of the embodiment of the present disclosure, because the second driving unit 12 of the cutting part 10 can drive the laser cutting knife 11 located above the conveying unit 21 to move along the second moving track based on the first moving track and the preset shape of the raw material plate driven by the conveying unit 21 of the transporting part 20, so as to cut the plate with the preset shape from the raw material of the plate, the plate cutting system in the embodiment of the present disclosure is no longer limited to only fixing the raw material plate when cutting the plate, and then the cutting knife is moved to cut the raw material plate, but can drive the laser cutting knife 11 to dynamically cut the plate with the preset shape along the second moving track based on the moving track of the raw material plate when the raw material plate moves along the first moving track, thereby completing the process of conveying the raw material plate and cutting the plate, therefore, the plate cutting system in the embodiment of the disclosure has better flexibility in plate cutting, and the efficiency of plate cutting is effectively improved.

In some possible embodiments, the plate cutting system in the embodiments of the present disclosure may be controlled by a numerical control device. The following is a detailed description of the plate cutting system according to the embodiment of the present disclosure, and it should be noted that the following description of the plate cutting system according to the embodiment of the present disclosure is not intended to limit the embodiment of the present disclosure.

In the disclosed embodiment, the platform 30 serves to support the cutting section 10 and the transportation section 20, and the platform 30 may be generally disposed on a support, for example, a floor, a roof, etc. Cutting portion 10 and transport portion 20 set up on the rack, conveniently guarantee that the panel cutting system in the embodiment of this disclosure can accomplish panel cutting work steadily.

In the embodiment of the present disclosure, the transportation portion 20 may be configured to transport a raw material plate, specifically, the raw material plate may be a raw material for plate cutting, and may be in a rectangular plane shape (of course, other shapes are also possible, and are not limited herein). When the raw material sheet is disposed on the conveying unit 21 of the transporting portion 20, the raw material sheet can be moved by the conveying unit 21, for example, along a first track when the conveying unit 21 is driven to move by the first driving unit 22. In the embodiment of the present disclosure, the first track may be a track with any shape, for example, the first track may be a straight track, that is, the raw material plate may be moved along a straight line by the conveying unit 21 when being disposed on the conveying unit 21, or in other possible embodiments, the first track may also be a curve, or another regular or irregular shape, which is not limited in this embodiment of the present disclosure.

In the embodiment of the present disclosure, cutting portion 10 can cut raw material plate, laser cutting knife 11 is located conveying unit 21 top, when needing to cut raw material plate, it can be to the laser beam of the surface emission high power density of raw material plate, the laser beam can heat raw material plate to thousands to tens of thousands degree centigrade in the very short time, this will make raw material plate and the position of laser contact take place to melt or gasify, blow away melting or gasification material from the joint-cutting utilizing high-pressure gas, thereby reach the purpose of cutting raw material plate.

In the embodiment of the present disclosure, the preset shape refers to a desired shape of the plate after the plate cutting system performs a cutting operation on the raw plate, and the preset shape can be reasonably set and changed by a worker according to actual needs. As an example for easy understanding, if the preset shape is a circular shape with a radius of 25 cm, the second driving unit 12 of the cutting part 10 may drive the laser cutting blade 11 to move along a second trajectory from above the raw material sheet based on the first trajectory and the preset shape to perform a cutting operation on the raw material sheet, and at the end of the movement of the laser cutting blade 11 along the second trajectory, a circular sheet with a radius of 25 cm may be obtained. It is to be understood that this is not intended to limit the disclosed embodiments, and the preset shape may be any other arbitrary shape, for example, a regular shape such as a triangle, a rectangle, etc., or other irregular shapes such as an airplane shape, a star shape, etc.

To be convenient to understand, when the plate cutting system in the embodiment of the present disclosure performs a plate cutting task, the raw plate is driven to move along the first track, the laser cutting knife 11 is driven to move along the second track, and when the laser cutting knife 11 moves along the second track, the laser cutting knife 11 moves along the track of the preset shape relative to the raw plate moving along the first track, so that the laser cutting knife 11 cuts the plate of the preset shape from the raw plate.

The specific structure of the second driving unit 12 in the embodiment of the present disclosure is not limited herein, and only needs to be able to fulfill the requirement and function of driving the conveying unit 21 to move so that the conveying unit 21 can drive the raw material sheet to move along the first track when the raw material sheet is disposed on the conveying unit 21. Since the first trajectory is a motion trajectory of the raw material plate when being driven by the conveying unit 21 to move, in some optional embodiments, the second driving unit 12 may drive the laser cutting knife 11 to move along the second trajectory based on a result of interpolating the first trajectory of the raw material plate according to the preset shape (that is, the second trajectory may be a motion trajectory of the laser cutting knife 11 after interpolating the first trajectory according to the preset shape, in some examples, interpolation may be linear interpolation or circular interpolation, which is determined according to actual conditions), when the laser cutting knife 11 moves along the second trajectory, since the raw material plate is moving at the same time, the laser cutting knife 11 after superimposing the motions of the raw material plate and the circular interpolation can cut along the preset shape from the raw material plate, so as to cut the plate with the preset shape, it can be seen that in the embodiment of the present disclosure, when the second driving unit 12 drives the laser cutting knife 11 to move along the second trajectory, the movement of the raw material plate driven by the conveying unit 21 is overlapped, so that the plate cutting operation can be performed more flexibly and more efficiently. Thereby panel cutting system in this embodiment of the disclosure also need not just confine to only fixed with raw materials panel like the panel cutting system among the prior art, remove the cutting knife again and cut raw materials panel, but can be when raw materials panel removes along first orbit, drive laser cutting knife 11 on the basis of raw materials panel's removal orbit and cut out the panel of predetermineeing the shape to raw materials panel along the second orbit dynamically, the process of carrying raw materials panel and carrying out panel cutting on one side has just so been accomplished, thereby make the flexibility of panel cutting system when panel cutting in this embodiment of the disclosure better, and effectively improved the efficiency of panel cutting.

In the embodiment of the present disclosure, specific structures of the conveying unit 21 and the first driving unit 22 are not limited as long as the respective functions can be satisfied. As an alternative example, referring to fig. 2, in the plate material cutting system, the first driving unit 22 includes a first motor 23 and a second motor 24, the first motor 23 includes a first transmission shaft 231, the second motor 24 includes a second transmission shaft 241, the first transmission shaft 231 is connected with the conveying unit 21, and the second transmission shaft 241 is connected with the conveying unit 21; when the first transmission shaft 231 and the second transmission shaft 241 rotate synchronously, the conveying unit 21 is driven to move, so that the conveying unit 21 drives the raw material plate to move along a first track on the first straight line when the raw material plate is arranged on the conveying unit 21.

Specifically, the first transmission shaft 231, i.e. the transmission shaft of the first motor 23, when the first motor 23 is operated, the first transmission shaft 231 rotates, and in the process, the first motor 23 can be controlled by a numerical control device through software to adjust the rotation speed of the first transmission shaft 231. Similarly, the second transmission shaft 241 is a transmission shaft of the second motor 24, and when the second motor 24 operates, the second transmission shaft 241 rotates, and in this process, the second motor 24 can be controlled by software to adjust the rotation speed of the second transmission shaft 241. The first transmission shaft 231 and the second transmission shaft 241 are connected with the conveying unit 21 of the conveying part 20, so that the first transmission shaft and the second transmission shaft cooperatively form a driving action on the conveying unit 21 when synchronously rotating, and the driving action is stable and reliable.

In addition, when the conveying unit 21 is driven, the raw material plate arranged on the conveying unit 21 is driven to move along the first track on the first straight line, so that the raw material plate can move towards two different directions on the same straight line according to an actual plate cutting task when moving, and the subsequent second driving unit 12 can drive the cutting part 10 to cut the raw material plate more flexibly according to the first track, so as to obtain the required plate with the preset shape.

Alternatively, the first line may be a line lying on a horizontal plane on which the stock sheet moves.

The specific arrangement positions of the first motor 23 and the second motor 24 are not limited herein, for example, in an alternative embodiment, the first transmission shaft 231 of the first motor 23 and the second transmission shaft 241 of the second motor 24 may be arranged in parallel at both ends of the conveying unit 21 and connected with the conveying unit 21, and may rotate synchronously.

In some alternative embodiments, a numerical control device may control the first transmission shaft 231 and the second transmission shaft 232 to rotate synchronously through electronic gear functions. For example, when the plate material cutting system is controlled by a numerical control device, the movements of the first transmission shaft 231 and the second transmission shaft 241 may be coupled (for example, through TRAILON command linkage), and then the electronic gear ratios of the first transmission shaft 231 and the second transmission shaft 241 are set, so that the first transmission shaft 231 and the second transmission shaft 241 complete synchronous rotation according to the set electronic gear ratio, so as to better drive the movement of the raw plate material to perform the interpolation movement in the plate material cutting system of the embodiment of the present disclosure (for example, the electronic gear ratio of the first transmission shaft 231 of the first motor 23 and the second transmission shaft 241 of the second motor 24 is set to be 1: 1, and the first transmission shaft 231 and the second transmission shaft 241 may move according to the set electronic gear ratio of 1: 1), after the electronic gear ratio is set, only the rotation of the first transmission shaft 231 may be programmed, the second transmission shaft 232 also moves synchronously with the first transmission shaft 231 according to the set electronic gear ratio (for example, in one example, the electronic gear ratio is 1: 1, the rotation speeds of the first transmission shaft 231 and the second transmission shaft 241 are both n, the rotation speed of the first transmission shaft 231 is increased to 2n, and the rotation speed of the second transmission shaft 241 is also automatically increased to 2n from n). Under the condition, the first transmission shaft 231 of the first motor 23 can be programmed and controlled, so that the first transmission shaft 231 and the second transmission shaft 241 can be controlled to move synchronously, and the raw material plate supported by the support assembly 25 can be driven to move along the first track in a coordinated manner, so that the technical difficulty of a worker using the plate cutting system in the embodiment of the disclosure is greatly reduced.

In the disclosed embodiment, the first transmission shaft 231 and the second transmission shaft 241 may be connected with the conveying unit 21 in any suitable manner, for example, without limitation, referring to fig. 3, in an alternative embodiment, the conveying unit 21 includes a support assembly 25, a transmission chain 26, a first sprocket 232 and a second sprocket 242, the support assembly 25 is connected to the transmission chain 26, the support assembly 25 is configured to support the raw material sheet when the raw material sheet is disposed on the conveying unit 21, the first sprocket 232 is fixedly connected to the first transmission shaft 231, the second sprocket 242 is fixedly connected to the second transmission shaft 241, the transmission chain 26 is connected with the first sprocket 232 in a matching manner, and the transmission chain 26 is connected with the second sprocket 242 in a matching manner; when the first transmission shaft 231 and the second transmission shaft 241 rotate synchronously, the first chain wheel 232 and the second chain wheel 242 are driven to rotate synchronously, and the first chain wheel 232 and the second chain wheel 242 drive the transmission chain 26 and the supporting component 25 to move, so that the raw material plate supported by the supporting component 25 moves along a first track on a first straight line.

Specifically, the first sprocket 232 of the conveying unit 21 of the embodiment of the present disclosure is connected to the first transmission shaft 231 through the transmission chain 26, the second sprocket 242 of the conveying unit 21 is connected to the second transmission shaft 241 through the transmission chain 26, and the transmission chain 26 and the support assembly 25 are driven to move by the first transmission shaft 231 and the second transmission shaft 241 which rotate synchronously, so that when a worker uses the plate cutting system to cut a plate with a preset shape, the worker can better drive the raw plate to move along the first straight line. In the disclosed embodiment, the first and

second sprockets

232, 242 can be identical in shape.

Since the first track is actually a motion track of the raw material plate when being moved by the first transmission shaft 231 of the conveying unit 21, and only the first transmission shaft 231 of the first motor 23 may be programmed and controlled at this time, in some optional embodiments, the second driving unit 12 may drive the laser cutting knife 11 to move along the second track based on a result of interpolating the first track of the raw material plate according to the preset shape (that is, the second track may be a motion track of the laser cutting knife 11 after interpolating the first track according to the preset shape), when the laser cutting knife 11 moves along the second track, since the raw material plate is also driven by the first transmission shaft 231 to move simultaneously, the laser cutting knife 11 can cut along the preset shape from the raw material plate after the superposition of the motions of the raw material plate and the second track, so as to cut the plate with the preset shape, it can be seen that in this embodiment, the second driving unit 12 drives the laser cutting knife 11 to move along the second track The movement of the raw material plate driven by the first transmission shaft 231 of the conveying unit 21 is equivalent to the superposition, so that the plate cutting operation can be performed more flexibly and efficiently.

Particularly, when supporting component 25 is connected on drive chain 26, can be driven synchronous motion by drive chain 26 to the raw materials panel that drives supporting component 25 and support removes, makes things convenient for laser cutting knife to cut raw materials panel along the second orbit in order to obtain the panel of predetermineeing the shape. The specific structure of the supporting assembly 25 is not limited in the embodiment of the present disclosure, and may be any optional structure capable of satisfying the requirement of supporting the raw material plate disposed on the conveying unit 21.

For example, in some of the alternative embodiments, referring to fig. 4, the support assembly 25 of the slab cutting system includes a plurality of support rods 251, the plurality of support rods 251 are connected to the driving chain 26 at intervals; at least two support bars 251 among the plurality of support bars 251 support the raw material sheet when the raw material sheet is set to the conveying unit 21.

Specifically, the plurality of support rods 251 may be connected to the drive chain 26 at different positions at the same distance, or may be connected to the drive chain 26 at different positions at different distances. And the support bar 251 may be connected by a vertical drive chain 26. When the plurality of supporting rods 251 are driven by the driving chain 26, at least two supporting rods 251 support the raw material plates, so as to ensure the stability of supporting the raw material plates, but it can be understood that how many supporting rods 251 support the raw material plates depends on the number of actual supporting rods, the spacing distance and the size of the raw material plates, and thus the embodiments of the present disclosure are not limited in any way. In the embodiment of the present disclosure, the supporting rod 251 may be made of a high temperature resistant material.

Because in this panel cutting system, laser cutting knife 11 can produce very big temperature when cutting raw materials panel, and the bracing piece 251 that sets up through the interval supports raw materials panel and can reduce the injury of high temperature to panel cutting system's conveying unit 21 when laser cutting knife 11 cuts.

The specific structure of the supporting rod 251 is also not particularly limited in the disclosed embodiment, and by way of example, referring to fig. 4, in some alternative embodiments, the supporting rod 251 includes a rod main body 252 and a plurality of supporting blocks 253, the plurality of supporting blocks 253 being disposed at intervals on the rod main body 252; when the raw material sheet is set to the conveying unit 21, at least a portion of the support blocks 253 of the at least two support bars 251 support the raw material sheet such that a space exists between the raw material sheet and the bar main body 252.

Specifically, the shape of the supporting block 253 may be set to any suitable shape, and the shapes of the supporting blocks 253 may be the same or different, which is not limited herein. Taking the plurality of supporting blocks 253 having the same shape as an example, the supporting blocks 253 may have a triangular shape, wherein two vertexes of the triangular plate are disposed on the rod main body 252 and the third vertexes of the triangular plate contact the raw material sheet, and the third vertexes of at least a portion of the supporting blocks 253 of the two supporting rods 251 contact the raw material sheet to support the raw material sheet, which is to be understood that the present disclosure is not limited thereto.

Obviously, since at least a portion of the support blocks 253 of at least two support rods 251 support the raw material plate in this alternative embodiment, so that there is a space between the raw material plate and the rod main body 252, the high temperature when the laser cutting knife 11 performs cutting can minimize damage to the rod main body 252 of the support rods 251.

Alternatively, the supporting block 253 may be detachably provided to the lever body 252, so that it can be easily removed and replaced after the supporting block 253 is damaged.

In some alternative embodiments, the plate cutting system in the embodiments of the present disclosure drives the laser cutting knife 11 to move along a second track on a first plane formed by a second straight line parallel to or coincident with the first straight line and a third straight line perpendicular to the second straight line based on the first track and the preset shape when the raw plate moves along the first track on the first straight line, so that the laser cutting knife 11 cuts the plate with the preset shape on the raw plate, wherein the first plane is parallel to the horizontal plane.

Specifically, when the plate material cutting system according to the embodiment of the present disclosure is operated, the raw plate material may be in a horizontal state when being disposed on the conveying unit 21, and when the raw plate material is carried by the conveying unit 21 driven by the first driving unit 22 to move along the first track of the first straight line, the raw plate material may move along the first track of the first straight line on a horizontal plane corresponding to the horizontal state of the raw plate material. It can be understood that the first plane formed by the second straight line and the third straight line is parallel to the horizontal plane of the raw material plate, in the embodiment of the present disclosure, the second driving unit 12 drives the laser cutting knife 11 to move along the second track on the first plane based on the first track and the second track, so that the laser cutting knife 11 can cut the raw material plate flexibly, so as to cut the plate with the preset shape from the raw material plate.

It can be understood that, if the second straight line coincides with the first straight line, the laser cutting knife 11 may be a plate that contacts the raw material plate and emits a laser beam to perform a cutting operation on the raw material plate to obtain a preset shape, if the second straight line is parallel to the first straight line, the laser cutting knife 11 may be a plate that emits a laser beam to perform a cutting operation on the raw material plate to obtain a preset shape under the condition of being apart from the raw material plate by a predetermined distance, and the predetermined distance may be set reasonably before the raw material plate is cut, so that the cutting operation may be performed, and no limitation is made herein.

Specifically, since the first track is actually a motion track of the raw material plate when being driven to move by the conveying unit 21, in some optional embodiments, the second driving unit 12 may drive the laser cutting knife 11 to move along the second track based on a result of interpolating the first track of the raw material plate according to the preset shape (that is, the second track may be a motion track of the laser cutting knife 11 after interpolating the first track according to the preset shape), when the laser cutting knife 11 moves along the second track, since the raw material plate is also moving at the same time, the laser cutting knife 11 after the superposition of the motions of the two is capable of cutting along the preset shape from the raw material plate, so as to cut the plate with the preset shape, it can be seen that, when the second driving unit 12 drives the laser cutting knife 11 to move along the second track, the motion of the raw material plate driven by the conveying unit 21 is equivalent to be superposed, therefore, the plate cutting operation can be carried out more flexibly and more efficiently.

Further, in the embodiment of the present disclosure, the second driving unit 12 is further configured to drive the laser cutting blade 11 to move along a fourth straight line perpendicular to the first plane during the movement of the laser cutting blade 11 along the second track on the first plane. Specifically, when laser cutting knife 11 is being driven by second drive unit 12 and is moving along the first plane that perpendicular to second straight line and third straight line formed, can be convenient for more nimble adjustment laser cutting knife 11 and the distance between the raw materials panel to make laser cutting knife 11 in this disclosed embodiment cut can be convenient more and nimble to the raw materials panel, thereby be convenient for further improve the efficiency of panel cutting.

In some more specific embodiments, the plate material cutting system in the embodiment of the present disclosure may be controlled by a numerical control device, and the numerical control device may be pre-established with a coordinate system of the operation of the laser cutting knife 11 driven by the second driving unit 12, wherein a cartesian rectangular coordinate system (for example, denoted as X-Y-Z coordinate system, where the X axis is perpendicular to the Y axis and the Z axis and the Y axis is perpendicular to the Z axis) may be established in space, for example, the X axis of the X-Y-Z coordinate system may be parallel to the second straight line, the Y axis may be parallel to the third straight line, and the Z axis may be parallel to the fourth straight line. The numerical control device can control the first driving unit 22 to drive the raw material plate on the conveying unit 21 to move along a first straight line (obviously, the first straight line can also be in an X-Y-Z coordinate system), and can also control the second driving unit 12 to move to drive the laser cutting knife 11 to move in the X-Y-Z coordinate system to cut the raw material plate. For example, when cutting a plate with a preset shape, the numerical control device controls the first driving unit 22 to move so as to drive the raw plate arranged on the conveying unit 21 to move along the positive direction of the X axis (i.e. one direction of the first straight line), and controls the second driving unit 12 to move to drive the laser cutting knife 11 to move, the movement of the raw material plate along the positive direction of the X axis (i.e. one direction of the first straight line) is superposed on the movement of the laser cutting knife 11 along the positive direction of the X axis (i.e. one direction of the second straight line), then the first track is interpolated into a second track based on the preset shape, when the laser cutting knife 11 moves along the second track, the movement of the raw material plate is superposed, and after the movement of the raw material plate is superposed to the movement of the laser cutting knife 11, the laser cutter 11 can finally cut the plate material along the preset shape from the raw plate material, so as to cut the plate material with the preset shape. Through such a mode, can guarantee effectively to carry out the precision of panel cutting to laser cutting knife 11. Of course, this example is not intended as a limitation on the disclosed embodiments.

For example, the first trajectory may be a unidirectional linear trajectory, the preset shape may be a circle, when the second driving unit 12 drives the laser cutting knife 11 to move along a curved second trajectory, which is equivalent to the movement of the raw material plate driven by the conveying unit 21, the laser cutting knife 11 can cut along the preset shape (for example, the aforementioned circle) from the raw material plate after the two move and overlap, so as to cut the plate (for example, a circular plate) with the preset shape, the flexibility is good, and the plate cutting efficiency is high.

In some alternative embodiments, the numerical control device may control the motion of the first transmission shaft 231 of the first motor 23 and the second transmission shaft 241 of the second motor 24 through an electronic gear function, specifically, by coupling the motion of the first transmission shaft 231 and the second transmission shaft 241 (for example, by a TRAILON command linkage), and then by setting the electronic gear ratio of the first transmission shaft 231 and the second transmission shaft 232, to make both the first transmission shaft 231 and the second transmission shaft 241 complete synchronous rotation according to a set electronic gear ratio, so as to better drive the movement of the raw sheet material to perform the interpolation motion in the sheet material cutting system in the embodiment of the present disclosure (for example, the electronic gear ratio of the first transmission shaft 231 of the first motor 23 and the second transmission shaft 241 of the second motor 24 is set to 1: 1, and the first transmission shaft 231 and the second transmission shaft 241 can move according to the set electronic gear ratio of 1: 1), after the electronic gear ratio is set, only the rotation of the first transmission shaft 231 can be programmed, and the second transmission shaft 232 can also move synchronously with the first transmission shaft 231 according to the set electronic gear ratio (for example, in one example, the electronic gear ratio is 1: 1, the rotation speeds of the first transmission shaft 231 and the second transmission shaft 241 are both n, the rotation speed of the first transmission shaft 231 is increased to 2n, and the rotation speed of the second transmission shaft 241 is also automatically increased to 2n from n). For example, the two are connected by first and second sprockets and a drive chain 26, such that a support assembly 25 attached to the drive chain 26 carries the sheet of stock material along a first path. Subsequently, the second driving unit 12 is controlled to drive the laser cutting knife 11 to move, and the movement of the raw material plate driven by the first transmission shaft 231 is superposed on the movement of the laser cutting knife 11, so that the laser cutting knife 11 moves along the second track, and the raw material plate moves along the track of the preset shape relative to the movement along the first track, so that the laser cutting knife 11 can finally cut the plate with the preset shape from the raw material plate.
