[0003] The existing plate cutting device performs cutting operations through a cutter head or a saw blade. The cutter head method has higher flexibility and precision than the saw blade method, and can be used for curved contour cutting. However, the cutter head method has lower cutting efficiency than the saw blade method. In order to improve the cutter head method, the existing technology increases the number of cutter heads so that two cutter heads are simultaneously responsible for cutting a target plate to improve the cutting efficiency. Although this cutting method improves the cutting efficiency, in this cutting method, the two cutter heads are fixed with different beams.

In addition, the cutter head avoidance time of this cutting method is longer, which affects the further improvement of the cutting efficiency.

[0022] S53: When the second cutter head reaches the F section, the second cutter head is controlled to cut along the F section.

[0023] In combination with the third possible plate cutting method of the first aspect, in a fourth possible plate cutting method of the first aspect, the cutting time required for the C segment is longer than the cutting time required for the D segment;

[0024] The cutting time required for the F segment is longer than the cutting time required for the E segment.

[0039] It can be seen from the above technical solutions that the present invention has the following advantages:

[0040] The plate cutting method provided by the present invention first obtains the contour position of the target plate; then generates a corresponding tool moving track according to the contour position; then divides the tool moving track into segment A and segment B through the starting point and the end point, and the starting point and the end point are respectively located on two interval-relative straight track segments in the tool moving track; then controls the first cutter head to cut from the starting point along segment A to the end point; finally controls the second cutter head to cut from the starting point along segment B to the end point, the first cutter head and the second cutter head are arranged on the same slide rail, the slide rail extends along the X direction or the Y direction, the extension direction of the slide rail is parallel to the extension direction of the straight track segment, the X direction and the Y direction are perpendicular, and the plane is parallel to the plate surface.

[0041] In addition, when cutting is performed using the first cutter head and the second cutter head disposed on the same slide rail, only the first cutter head and the second cutter head need to avoid each other on the slide rail. The avoidance time required is shorter than that of the crossbeam, thereby further improving the cutting efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Embodiments of the present invention provide a plate cutting method, device, electronic device and computer-readable storage medium, which are used to solve the technical problem that the cutting accuracy of the plate cut by drilling in the prior art is low.

[0045] In order to make the purpose, features and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments.

For ordinary technicians in this field, the specific meanings of the above terms in the embodiments of the present application can be understood according to specific circumstances.

[0048] The existing plate cutting device performs cutting operations through a cutter head or a saw blade. The cutter head method has higher flexibility and precision than the saw blade method, and can be used for curved contour cutting. However, the cutter head method has lower cutting efficiency than the saw blade method. In order to improve the cutter head method, the existing technology increases the number of cutter heads so that two cutter heads are simultaneously responsible for cutting a target plate to improve the cutting efficiency. Although this cutting method improves the cutting efficiency, in this cutting method, the two cutter heads are fixed with different beams. The limit errors of different cutter heads are superimposed on the processing errors of the two cutter heads themselves, which makes the overall cutting error larger, resulting in a larger step at the interface, affecting the quality of the finished product. In addition, the cutter head avoidance time of this cutting method is longer, which affects the further improvement of the cutting efficiency.

[0049] Embodiment 1

[0050] See also Figure 1 , a plate cutting method provided by an embodiment of the present invention comprises:

[0051] S1: Get the contour position of the target plate.

[0052] Specifically, the target plate is a plate with a smaller area that needs to be cut from a plate with a larger area (ie, the plate to be cut), and the contour position of the target plate is the position of the contour of the target plate in the plate to be cut.

[0053] S2: Generate the corresponding tool movement trajectory according to the contour position.

[0054] Specifically, the tool path is the path that the cutting tool needs to take to cut the target plate. The shape outlined by the tool path is similar to the contour shape of the target plate and is larger than the contour shape of the target plate. For example, when the cutting tool is a circular cutting head, the tool path shape on the outside and the contour shape on the inside form a ring with a width equal to the radius of the head. The tool path is used to control the movement of the guide rail.

[0055] S3: Divide the tool moving trajectory into segment A and segment B through the starting point and the end point, wherein the starting point and the end point are respectively located on two straight line trajectory segments which are spaced opposite to each other in the tool moving trajectory.

[0056] Specifically, the target plate needs to be cut out from the plate to be cut, and the knife track needs to present a closed shape, such as a square, rectangle, circle, etc. In this step, the knife track is divided into two parts—segment A and segment B. The two intersection points of segment A and segment B are the starting point and the end point. The straight line track segment is a certain part of the knife track that appears as a straight line. The starting point and the end point are respectively located on two parallel straight line track segments in the knife track. That is, the shape outlined by the knife track needs to include at least two parallel straight lines in order to apply the following steps, which limits the applicable scenarios of the following steps.

[0057] S4: Control the first cutting head to cut along section A from the starting point to the end point.

[0058] S5: Control the second cutter head to cut along section B from the starting point to the end point. The first cutter head and the second cutter head are arranged on the same slide rail. The slide rail extends along the X direction or the Y direction. The extension direction of the slide rail is parallel to the extension direction of the straight track segment. The X direction and the Y direction are perpendicular, and the plane is parallel to the plate surface.

[0059] Specifically, because the first cutter head and the second cutter head are arranged on the same slide rail, when the first cutter head cuts at the position corresponding to the starting point, it will form an obstacle to the second cutter head. Therefore, when the first cutter head moves to a position that no longer forms an obstacle to the second cutter head, the second cutter head is controlled to enter the position corresponding to the starting point, and then cuts along section B to the end point. It should be noted that the specifications and models of the first cutter head and the second cutter head are consistent. In order to ensure that the initial positioning of the first cutter head and the second cutter head are consistent, the second cutter head is started to cut after the second cutter head enters the cutting gap corresponding to the starting point (the cutting gap is generated by the cutting of the first cutter head), that is, by ensuring that the second cutter head does not cut the plate when entering the cutting gap. Furthermore, a sensor can be set to detect the resistance encountered by the second cutter head when entering. When the resistance reaches a certain value, it is determined that the entry position is incorrect, and the entry position is recalibrated and adjusted.

[0060] The beneficial effects of this embodiment include:

[0061] ① By controlling the first cutter head and the second cutter head to cut the plate in different directions from the same starting point, the second cutter head that enters later can be limited by the trace of the previous cutting, thereby ensuring the consistency of the initial positioning of the first cutter head and the second cutter head and reducing the initial positioning error. At the same time, because the first cutter head and the second cutter head used for cutting are set on the same slide rail, the limit error is reduced, thereby improving the cutting accuracy and ensuring the cutting quality.

[0062] ② The first cutter head and the second cutter head disposed on the same slide rail are used for cutting. The first cutter head and the second cutter head only need to avoid each other on the slide rail. Compared with the avoidance of the crossbeam, the avoidance time required is shorter, thereby further improving the cutting efficiency.

[0063] Optimization of the plate cutting method: In order to further improve the cutting efficiency, the specific positions of the starting point and the end point are optimized and designed. Specifically, the starting point is used as the dividing point, and the straight track segment where the starting point is located is divided into segments C and D. The position of the starting point is determined based on the condition that the difference in the time of cutting between segments C and D is equal to the avoidance time S of the first cutter head and the second cutter head; the end point is used as the dividing point, and the straight track segment where the end point is located is divided into segments E and F. The position of the end point is determined based on the condition that the difference in the time of cutting between segments E and F is equal to the avoidance time S of the first cutter head and the second cutter head. According to the specific position of the starting point selected in this way, the second cutter head can be controlled to quickly enter the position corresponding to the starting point for cutting when the first cutter head no longer forms an obstacle to it. At the same time, the first cutter head and the second cutter head can reach the two ends of the straight track segment where the starting point is located at the same time, so that cutting can be performed in another direction at the same time, shortening the waiting time of the first cutter head and the second cutter head, thereby improving the cutting efficiency; according to the specific position of the end point selected in this way, the simultaneous operation time of the first cutter head and the second cutter head on the straight track segment where the end point is located is maximized, thereby improving the cutting efficiency. Accordingly, step S5 is optimized as follows: after a time period of S, the second cutter head is controlled to start cutting along segment B from the starting point to the end point, that is, when the first cutter head no longer hinders the second cutter head from entering the position corresponding to the starting point, the second cutter head is immediately controlled to enter the position to perform cutting operations. Furthermore, when the first cutter head and the second cutter head are performing cutting operations approaching the end point along the straight track segment where the end point is located, when the first cutter head and the second cutter head are about to touch each other, one of the two cutter heads is controlled to stop operating, and the other one is allowed to operate alone.

[0064] Exemplarily: the tool moving trajectory is divided into segment A and segment B by the starting point and the end point, segment A includes segment C, segment E and segment G, wherein segment C is a part of the straight line trajectory segment between the starting point and segment G, segment E is a part of the straight line trajectory segment between the end point and segment G, segment C and segment E are parallel to the X direction, segment G is opposite to the Y direction, that is, the projection length of segment G on the straight line in the Y direction is equal to the spacing between segment C and segment E; segment B includes segment D, segment F and segment H, wherein segment D is a part of the straight line trajectory segment between the starting point and segment H, segment F is a part of the straight line trajectory segment between the end point and segment H, segment D and segment F are parallel to the X direction, segment H is opposite to the Y direction, that is, the projection length of segment H on the straight line in the Y direction is equal to the spacing between segment D and segment F; step S5 is specifically:

[0065] S51: After the first cutter head starts cutting along segment C from the starting point for a period of time S, the second cutter head is controlled to start cutting along segment D from the starting point.

[0066] S52: When the first cutter head reaches the G section and the second cutter head reaches the H section, you can choose to control the plate to move along the Y direction, that is, keep the slide rails that limit the first cutter head and the second cutter head stationary, and then control the plate to move along the Y direction, so that the part of the plate that needs to be cut gradually approaches the first cutter head and the second cutter head. In this case, the first cutter head only needs to move along the X direction on the slide rail to ensure that it is always on the G section. Similarly, the second cutter head only needs to move along the X direction on the slide rail to ensure that it is always on the H section. You can also control the first cutter head and the second cutter head to cut along the G section and the H section respectively at the same time. In this case, the plate remains moving and the slide rail is controlled to move along the Y direction, that is, the first cutter head and the second cutter head actively approach the part of the plate that needs to be cut, and at the same time control the first cutter head and the second cutter head to move along the slide rail in the X direction to ensure that the first cutter head is always on the G section and the second cutter head is always on the H section.

[0067] S53: When the second cutter head reaches the F section, the second cutter head is controlled to cut along the F section toward the end point. At this time, the first cutter head has also reached the E section, so the first cutter head is controlled to cut along the E section toward the end point at the same time.

[0068] Further optimization of the plate cutting method: when the lengths of the E and F segments are equal, the cutting time required for the C segment is set to be longer than the cutting time required for the D segment, that is, the cutting time required for the C segment is equal to the cutting time required for the D segment plus the avoidance time S; the cutting time required for the F segment is set to be longer than the cutting time required for the E segment, that is, the cutting time required for the F segment is equal to the cutting time required for the D segment plus the avoidance time S. In this way, it can be ensured that the workload of the first cutter head and the second cutter head in a cutting operation is the same, so that the wear of the first cutter head and the second cutter head is basically the same, avoiding large cutting errors caused by different wear of the first cutter head and the second cutter head, and ensuring cutting accuracy. Based on the principle that the workload of the two cutter heads is the same or as close as possible, when the lengths of the E and F segments are not equal, the specific positions of the starting point and the end point can be adjusted according to the actual situation while ensuring that the efficiency remains unchanged. For example, when the F segment is significantly longer than the E segment, the starting point and the end point can be set at a position closer to the F segment, so that the workload of the first cutter head and the second cutter head is close.

[0069] Another optimization of the plate cutting method: The aforementioned cutting method is only applicable to the case where the tool moving track has two spaced parallel straight track segments, and is not universal. In order to make the method universal, the following steps are added after step S2 and before step S3:

[0070] S21: dividing the tool moving trajectory into a straight trajectory segment and a non-straight trajectory segment according to the coordinate information of the tool moving trajectory;

[0071] S22: Determine whether there are two parallel straight line track segments;

[0072] S23: In the following, the extension direction of the slide rail is parallel to the X direction. If there are two parallel linear track segments, the aforementioned cutting method is applicable, so step S3 is executed; if there are no two parallel linear track segments, the first cutter head or the second cutter head is controlled to cut along the portion of the tool moving track opposite to the X direction, that is, only one of the cutter heads is used to cut the portion opposite to the X direction. It should be understood that when cutting this portion, the plate or the slide rail should be controlled to move in the Y direction accordingly. Of course, when there is only one linear track segment, the knife moving method on the linear track segment where the starting point is located in the aforementioned method can also be used to control the first cutter head and the second cutter head to move on the linear track segment for cutting operation; when the first drill head (or the second cutter head) completes the cutting of the portion to be cut opposite to the X direction, the first cutter head and the second cutter head are controlled to cut along the portion of the tool moving track opposite to the Y direction. This portion is the same as the cutting of the G segment and the H segment in the aforementioned cutting method. The plate can also be controlled to move in the Y direction, which will not be repeated here.

Specifically, the slide rail includes a guide rail for guiding the first cutter head and the second cutter head to slide and a rack for driving the first cutter head and the second cutter head, and a rotating motor with a gear on a rotating shaft sleeve is fixed on the first cutter head and the second cutter head, and the gear is meshed with the rack, so that the rotating motor drives the gear to rotate so that the gear and the rack are continuously meshed, thereby driving the first cutter head to move along the X direction. The specific working process of the first cutter head and the second cutter head can refer to the corresponding process in the aforementioned method embodiment, and will not be repeated here.

[0075] In addition, in order to drive the plate to move in the Y direction, a plate moving unit is added to the plate cutting device. For example: the plate moving unit includes two clamps that can move along the Y direction, the clamps include a cylinder and two relative flat plates, the cylinder drives the two flat plates to approach each other to achieve clamping of the plate, and then the movement in the Y direction is achieved through the cooperation of a rotating motor with a gear on the rotating shaft sleeve and a rack.
