[0002] When ceramic slabs emerge from the press production line, they are continuous blanks that need to be cut online into rectangular plates of specified sizes using cutting equipment. Current technology for cutting ceramic slabs using plate cutting devices suffers from long cutting times and low production efficiency. Summary of the Invention

[0003] The purpose of this invention is to disclose a double-beam cutting device and its cutting method to solve the technical problem of low cutting efficiency in the prior art.

[0004] To achieve the above objectives, a first aspect of the present invention discloses a cutting method based on a double-beam cutting device, comprising: The sheet material includes, along the X direction, a side-cutting section, a middle-cutting section, and another side-cutting section connected in sequence. The outer end of the side-cutting section away from the middle-cutting section is the edge of the sheet material. The X direction refers to the direction parallel to the plane in which the sheet material is located. The cutting method includes: The two edge cutting plate segments are cut by at least two cutting blades along the same cutting line in the X direction; The sheet material is cut by cutting it at the middle of the cutting plate segment. As an optional implementation, The step of cutting the two edge segments along the same cutting line in the X direction using at least two cutting blades includes: Both cutting blades are controlled to cut in opposite directions from the outer end of the edge cutting plate segment toward the middle cutting plate segment.

[0005] As an optional implementation method, The step of cutting the plate by the intermediate cutting segment of the plate includes: One of the two cutting blades used to cut the edge cutting plate segment is controlled to retreat after cutting the edge cutting plate segment, while the other blade continues to cut towards the middle cutting plate segment and cuts the plate.

[0006] As an optional implementation method, The step of cutting the two edge segments along the same cutting line in the X direction using at least two cutting blades includes: Control two cutting knives to perform cutting in the same direction. One of the cutting knives cuts from the outer end of one side cutting plate segment towards the middle cutting plate segment, and the other cutting knife cuts from the inner end of the other side cutting plate segment towards the outer end.

[0007] As an optional implementation manner, The step of cutting the sheet material at the middle cutting plate segment of the sheet material includes: Control the cutting knife that cuts from the outer end of the side cutting plate segment towards the middle cutting plate segment to continue cutting towards the middle cutting plate segment and cut off the sheet material. As an optional implementation manner, The length of the cutting line of the sheet material in the X direction is L; The relationship between the starting cutting position l1 of the cutting knife that cuts from the inner end of the side cutting plate segment towards the outer end and L is: 0.5L - R ≤ l1 ≤ 0.5L + R, where R is the radius size of the cutting knife.

[0008] As an optional implementation manner, Before the step of controlling the cutting knife that cuts from the outer end of the side cutting plate segment towards the middle cutting plate segment to continue cutting towards the middle cutting plate segment and cut off the sheet material, the cutting method further includes: Obtain the distance l2 between the cutting point where the cutting knife that cuts from the inner end of the side cutting plate segment towards the outer end is located relative to the sheet material in the X direction and the outer end of the other uncut side cutting plate segment; Determine that the distance l2 is within a preset range, where the relationship between the distance l2 and the preset range of L is: 0.5L ≤ l2 ≤ 0.5L + 2R; Start the other cutting knife to cut from the outer end of the other uncut side cutting plate segment towards the middle cutting plate segment and cut off the middle cutting plate segment.

[0009] The second aspect of the present invention discloses a double-beam cutting device, including: A frame; Two groups of cutting mechanisms, arranged in parallel along the X direction on the frame. Each cutting mechanism includes at least one cutting knife. The two cutting knives corresponding in the X direction are respectively used to walk in the same direction or in opposite directions along the X direction to cut the same cutting line of the sheet material in the X direction, and one of the cutting knives is used to cut the sheet material in the middle area of the sheet material to achieve cutting of the sheet material.

[0010] As an optional implementation, the double-beam cutting device further includes a conveying platform for conveying the sheet metal along the Y direction; And / or, The double-beam cutting device further includes a straightness detection sensor, which is installed on at least one of the cutting mechanisms along the X direction and is used to detect the straightness of the two cutting blades along the X direction.

[0011] As an optional implementation, the double-beam cutting device further includes a centering mechanism and a limiting mechanism; Along the X direction, a centering mechanism is provided on one side of the conveying platform, and a limiting mechanism is provided on the other side of the conveying platform. The centering mechanism is used to adjust the placement position of the plate along the X direction, and the limiting mechanism is used to abut against the plate.

[0012] As an optional implementation method, The cutting mechanism includes the cutting blade, crossbeam, cutting drive component, lifting drive component, walking drive component, first frame and second frame; The cutting drive is mounted on the first frame, and the cutting blade is located at the output end of the cutting drive. The lifting drive is installed on the second frame and connected to the first frame to drive the cutting drive and the cutting blade to move up and down. The walking drive component is installed on the crossbeam and connected to the second frame to drive the first frame, the cutting drive component, the lifting drive component, and the cutting blade to move along the X direction.

[0013] Compared with the prior art, the advantages of the double-beam cutting device and cutting method of the present invention are as follows: The double-beam cutting device of the present invention, by setting two cutting mechanisms, allows the cutting blade in each cutting mechanism to cut the plate simultaneously. Compared with the method of cutting the plate by a single cutting blade moving back and forth, it reduces the back-and-forth movement time of the cutting mechanism during the cutting process, resulting in higher cutting efficiency and thus improving enterprise benefits.

Unless otherwise stated, "a plurality of" means two or more.

[0022] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0023] In the existing technology, when cutting the board 200 (such as extra-large boards like foamed ceramic boards), the cutting blade cuts directly from one side of the foamed ceramic board to the other side, resulting in low production efficiency.

[0024] The inventors conducted in-depth research and practice, discovering that the existing cutting methods, besides being inefficient, are problematic for extra-large slabs like foamed ceramic panels. These panels are very wide, reaching over 1.8 meters, with some reaching 2.6 meters – significantly wider than large stone or ceramic slabs. Because the foamed ceramic panels are supported by a conveyor belt and fed under the cutting blade 300, and due to the brittle nature of the panels and the unevenness of the belt, they are prone to breakage. This breakage not only affects the yield rate but also further impacts production efficiency.

[0025] Therefore, when cutting the foamed ceramic board, the inventors attempted to start cutting from one side of the foamed ceramic board until they reached the middle area, so that the middle area was connected. For example... Figure 1 As shown by arrow a, the cutting blade 300 is then raised away from the foamed ceramic board and moved directly to the other side of the board 200. The cutting process begins from the other side, using a back-and-forth motion. Figure 2 As shown by arrow b, the cutting point of the foamed ceramic board can be located in the middle region c of the foamed ceramic board. In this way, the middle of the foamed ceramic board is the stress point, and the unevenness at both ends is distributed by cutting in the middle, which is equivalent to shortening the lever arm, thereby reducing the probability of the foamed ceramic board breaking and reducing the scrap rate.

[0026] However, the inventors further discovered that while this method of cutting foamed ceramic panels reduced the scrap rate, the entire cutting process was time-consuming and inefficient because each cutting blade 300 had to start cutting from one side of the foamed ceramic panel, then move to the other side and cut back and forth.

[0027] To address the aforementioned technical problems of low cutting efficiency and poor cutting quality in 200mm sheet metal cutting, please refer to [link / reference]. Figures 3 to 6 The double-beam cutting device 100 provided in the first embodiment of the present invention includes a frame 10, a support platform 20, and two sets of cutting mechanisms 30. Since the width of a single cutting mechanism 30 of the double-beam cutting device 100 is relatively large, greater than 0.7 meters to more than 0.9 meters, and some can approach 1 meter, the combined width of the two sets of cutting mechanisms 30 is close to 2 meters, which is suitable for cutting large plates such as foamed ceramic panels.

[0028] Please refer to Figure 3 The frame 10 has an installation space 11; two sets of cutting mechanisms 30 are arranged side by side along the X direction on the frame 10 and above the support platform 20. Each cutting mechanism 30 includes at least one cutting blade 31. The two corresponding cutting blades 31 along the X direction are used to move in the same direction or opposite directions along the X direction to cut the plate 200 along the same cutting line in the X direction. One of the cutting blades 31 is used to cut the plate 200 in the middle area of ​​the plate 200, thereby realizing the division of the plate 200. The X direction refers to the direction parallel to the plane of the plate, such as the width direction or length direction of the plate 200. The cutting line can be a straight line.

[0029] The aforementioned double-beam cutting device 100, by setting two cutting mechanisms 30, allows the cutting blades 31 in each cutting mechanism 30 to cut the plate 200 simultaneously. Compared to the method of cutting the plate 200 by using a single cutting blade 31 to move back and forth, this reduces the time for the cutting mechanism to move back and forth during the cutting process, resulting in higher cutting efficiency and thus improving the company's profitability.

[0030] In this embodiment, cutting refers to cutting the board 200 while the board 200 is still connected and not separated; slicing refers to cutting the board 200 along a straight line so that the board 200 is divided into two parts along a cutting line; and dividing refers to cutting the board 200 into at least two parts.

[0031] Understandably, each cutting mechanism 30 may include multiple cutting blades 31. When multiple cutting blades 31 are provided, they are spaced apart along the Y direction. Specifically, the cutting mechanism 30 also includes a crossbeam 32 extending along the Y direction, on which the multiple cutting blades 31 are spaced apart, so that they can be driven by a single crossbeam 32 to move synchronously along the X direction. When each cutting mechanism 30 is provided with multiple cutting blades 31, the multiple cutting blades 31 in the two cutting mechanisms 30 are arranged one-to-one along the X direction, so that every two corresponding cutting blades 31 can cut the plate 200 along the same cutting line in the X direction.

[0032] It should be noted that you should refer to [link / reference]. Figure 3 , Figure 4 and Figure 6 Since the cutting blade 31 needs to rotate to cut the plate 200, the cutting mechanism 30 also includes at least one cutting drive 33. The number of cutting drive 33 corresponds to the number of cutting blades 31, so that the cutting blade 31 can be driven to rotate by the cutting drive 33, thereby cutting the plate 200. For example, the cutting drive 33 can be configured to include a motor and a reducer, and the motor can drive the cutting blade 31 to rotate.

[0033] Furthermore, to improve production efficiency, the double-beam cutting device 100 in this embodiment also includes a conveying platform 40. The conveying platform 40 is used to convey the sheet metal 200 along the Y direction, thereby conveying the sheet metal 200 to the area below the cutting mechanism 30. After the cutting mechanism 30 completes the cutting of the sheet metal 200, the conveying platform 40 simultaneously sends away the cut sheet metal 200 and simultaneously sends in the sheet metal 200 to be cut, thereby synchronizing the conveying and cutting rhythm of the sheet metal 200 and improving production efficiency. In one embodiment, the conveying platform 40 can be configured as a conveyor belt.

[0034] In another embodiment, the double-beam cutting device 100 of this embodiment may further include a support platform 20, which is disposed in the installation space 11 and is used to support the plate 200, so that the plate can have a certain height to facilitate cutting by the cutting blade 31. At the same time, the conveying platform 40 may be disposed on top of the support platform 20; or in another embodiment, the support platform 20 may also be used as a conveyor.

[0035] Please see Figure 4 and Figure 5 In one embodiment of the present invention, in order to improve the cutting accuracy of the plate 200, the double beam cutting device 100 further includes a centering mechanism 50. Along the X direction, at least one side of the conveying platform 40 is provided with a centering mechanism 50. The centering mechanism 50 is used to adjust the placement position of the plate 200 along the X direction. For example, a centering mechanism 50 can be provided on one side of the plate 200 and a limiting plate can be provided on the other side. The limiting plate restricts the placement position of the plate 200 along the X direction. The centering mechanism 50 is used to drive the plate 200 to move along the X direction, thereby achieving the centering of the placement position of the plate 200 and corresponding to the placement position of the cutting mechanism 30, so as to improve the cutting accuracy.

[0036] Specifically, in this embodiment, when centering the plate 200, the double-beam cutting device 100 further includes a limiting mechanism 70. Along the X direction, a centering mechanism 50 is provided on one side of the conveying platform 40, and a limiting mechanism 70 is provided on the other side. Thus, when the position of the plate 200 along the X direction is adjusted by the centering mechanism 50, the limiting mechanism 70 on one side blocks the placement of the plate 200, ensuring the accuracy of the adjusted position of the plate 200. For example, the aforementioned limiting plate can be set as the limiting mechanism 70 in this embodiment; or in another embodiment, the limiting mechanism 70 can also be provided with a drive source that drives the limiting plate to move, so as to adjust the distance between it and the centering mechanism 50.

[0037] Specifically, in this embodiment, the centering mechanism 50 and the limiting mechanism 70 are located on opposite sides of the conveying platform 40 along the X direction.

[0038] Please refer to Figure 5The centering mechanism 50 in this embodiment includes a centering drive member 51, a mounting plate 52, and a first roller 53 mounted on the mounting plate 52. The mounting plate 52 is connected to the centering drive member 51. For example, the centering drive member 51 can be configured to have a drive cylinder along the X direction, and the movement of the first roller 53 along the X direction can be achieved by extending and retracting the piston shaft of the drive cylinder. Alternatively, it can be configured to be driven by a drive motor and a lead screw, and the rotation of the motor can drive the first roller 53 to move along the X direction. In this way, since the first roller 53 abuts against the plate 200, the plate 200 is driven to move along the X direction, thus centering the plate 200. At the same time, since the first roller 53 and the side of the plate 200 are subjected to rolling friction, the contact area between the two is small, avoiding scratches on the plate 200. Specifically, the centering drive member 51 in this embodiment is configured as a drive cylinder.

[0039] Understandably, since the plate 200 has a certain extension length along the Y direction, multiple centering mechanisms 50 and multiple limiting mechanisms 70 can be provided on each side of the plate 200.

[0040] The limiting mechanism 70 can be configured to include a positioning plate and a second roller. The positioning plate is installed on the support platform 20, and the second roller is installed on the side facing the positioning plate. The second roller contacts the plate 200 to reduce contact friction and avoid scratching the plate 200.

[0041] It should be noted that since the cutting mechanism 30 as a whole needs to move along the X direction, that is, it can move along the X direction under the drive of the crossbeam 32, the cutting mechanism 30 also includes a walking drive component 35. For example, the walking drive component 35 is set on the crossbeam 32 and is configured as a drive motor, a transmission shaft and a gear. The transmission shaft extends along the Y direction, one end of the transmission shaft is connected to the drive motor and the other end is connected to the gear. A rack 60 extending in the X direction is set on the frame 10. The gear and the rack mesh with each other, thereby driving the entire cutting mechanism 30 to move along the X direction.

[0042] Understandably, in order to ensure the stability of the cutting mechanism 30 moving in the X direction, a rack 60 is provided at both ends of the frame 10 in the Y direction.

[0043] Specifically, the two cutting blades 31 in the two cutting mechanisms 30, corresponding along the X direction, cut the sheet metal 200 in the following ways: Method 1: (1) Two cutting blades 31 are placed on the same side of the board 200. First, drive one cutting blade 31 to start cutting along the middle area of ​​the board 200 and cut to the edge of the board 200. (2) During the process of the first-started cutting blade 31 cutting the board 200, another cutting blade 31 is also started at the same time. It starts cutting from the edge of the board 200 and gradually moves towards the middle area, thereby cutting off the middle area of ​​the board 200, thus achieving the cutting of the entire board 200.

[0044] Method 2: (1) Place one cutting blade 31 in the middle area of ​​the board 200 and another cutting blade 31 on one side of the board 200; (2) The cutting blade 31 located in the middle area of ​​the board 200 first begins to cut the middle area of ​​the board 200; (3) During the cutting process of the first-started cutting blade 31, another cutting blade 31 is started simultaneously, starting from the edge of the board 200 and gradually moving towards the middle area, thereby cutting off the middle area of ​​the board 200.

[0045] Method 3: (1) Place the two cutting blades 31 on both sides of the board 200; (2) Simultaneously start two cutting blades 31 to cut from each side edge of the board 200, and both gradually move towards the middle area of ​​the board 200. (3) When the cutting gradually reaches the middle area, one of the cutting blades 31 retracts to the initial position and cuts the board 200 with one of the cutting blades 31.

[0046] Therefore, all three cutting methods described above can cut the middle area of ​​the board 200 to achieve the cutting of the board 200.

[0047] Understandably, since the cutting blade 31 needs to move up and down to get closer to or away from the plate 200, the cutting mechanism 30 also includes a lifting drive 34. The lifting drive 34 is used to drive the cutting blade 31 to move up and down. Thus, under the drive of the lifting drive 34, the cutting blade 31 can get closer to the plate 200 to cut the plate 200, and after the cutting is completed, it can be lifted relative to the plate 200 to get away from the plate 200.

[0048] Specifically, the cutting mechanism 30 in this embodiment includes a cutting blade 31, a crossbeam 32, a cutting drive component 33, a lifting drive component 34, a traveling drive component 35, a first frame 36, and a second frame 37. The cutting drive component 33 is mounted on the first frame 36, and the cutting blade 31 is located at the output end of the cutting drive component 33. The lifting drive component 34 is mounted on the second frame 37 and connected to the first frame 36 to drive the cutting drive component 33 and the cutting blade 31 to perform lifting movements. The traveling drive component 35 is mounted on the crossbeam 32 and connected to the second frame 37 to drive... The first frame 36, the cutting drive 33, the lifting drive 34, and the cutting blade 31 move along the X direction, thereby driving the cutting blade 31 to rotate and cut the plate 200. The first frame 36, the cutting drive 33, the lifting drive 34, and the cutting blade 31 move along the X direction, thereby cutting the plate 200 of a certain length along the X direction. The lifting drive 34 drives the cutting blade 31 to move up and down to move closer to or away from the plate 200.

[0049] In addition, please see Figure 6 Since the two cutting blades 31 along the X direction need to travel along the same cutting line, in order to ensure the straightness of the two cutting blades 31, the double beam cutting device 100 also includes a straightness detection sensor 80. The straightness detection sensor 80 can be installed on at least one cutting mechanism 30 along the X direction to detect the straightness of the two cutting blades 31 along the X direction. For example, the straightness detection sensor 80 can be set as an infrared sensor. When the infrared light emitted by the infrared sensor on one cutting mechanism 30 can always illuminate the other cutting mechanism 30, it can be ensured that the two cutting blades 31 in the two cutting mechanisms 30 are in a collinear state.

[0050] The aforementioned double-beam cutting device 100, by arranging two cutting mechanisms 30 along the X direction on the frame 10, allows the cutting blades 31 in the two cutting mechanisms 30 to simultaneously cut the same cutting line of the sheet 200, thereby improving the cutting efficiency of the sheet 200 and thus enhancing enterprise benefits; by setting up a conveyor platform 40, the cut sheet 200 can be transported away in a timely manner and the sheet 200 to be cut can be transported in, realizing the synchronization of cutting and feeding and improving productivity; by setting up a centering mechanism 50 and a limiting mechanism 70, the cutting position of the sheet 200 can be adjusted, improving cutting accuracy.

[0051] Please see Figures 7 to 11 The second embodiment of this application provides a cutting method based on a double-beam cutting device for cutting a plate 200.

[0052] Please refer to Figure 8The sheet material 200 includes, along the X direction, a sequentially connected edge-cut segment 210, a middle-cut segment 220, and another edge-cut segment 210. The outer end of the edge-cut segment 210 away from the middle-cut segment 220 forms the edge of the sheet material 220. The middle-cut segment 220 is located between the two edge-cut segments 210. The position of the middle-cut segment 220 is relative to the position of the edge-cut segments 210; that is, the middle-cut segment 220 does not include the edge of the sheet material 220. The X direction refers to the direction parallel to the plane containing the sheet material 220.

[0053] The cutting method 400 includes the following steps: S41, the two edge cutting plate segments 210 are cut along the same cutting line in the X direction by at least two cutting blades 31; Specifically, when two cutting blades 31 are provided, two cutting mechanisms 30 are mounted separately along the X direction on the frame 10, wherein each cutting mechanism 30 includes at least one cutting blade 31.

[0054] In this step, the cutting mechanism 30 is installed on the frame 10 to prepare for cutting.

[0055] It should be noted that each cutting mechanism 30 may include one cutting blade 31 or multiple cutting blades 31. When the cutting mechanism 30 includes multiple cutting blades 31, the multiple cutting blades 31 are distributed along the Y direction, and the multiple cutting blades 31 in the two cutting mechanisms 30 correspond one-to-one with each other along the X direction to form a group.

[0056] In this process, when cutting the sheet material 200, the cutting method is set to multiple cutting segments, with each cutting blade 31 having its own corresponding cutting segment. For example, each cutting blade 31 can cut from each edge of the sheet material 200 towards the middle cutting segment 220, or each cutting blade 31 can cut from the middle of the sheet material 200 towards the edge. Furthermore, when providing the sheet material 200, it can be supported by a support platform 20.

[0057] In this step, the plate 200 is prepared using the support platform 20.

[0058] In this embodiment, the edge-cutting segment 210 refers to a portion of the board 100 with a certain length along the X direction from the edge of the board 200 toward the middle position, and the middle-cutting segment 220 refers to a portion of the board 100 with a certain length located in the middle region of the board 200 along the two edges in the X direction away from the board 200.

[0059] Furthermore, in this embodiment, the total cutting length of the two edge cutting segments 210 and the middle cutting segment 220 along the X direction is L, that is, each edge cutting segment 210 and the middle cutting segment 220 has a certain length along the X direction. For example, in one embodiment, the length of the edge cutting segment 210 along the X direction can be set to 2 / 5L, and the length of the middle cutting segment 220 along the X direction can be set to 1 / 5L.

[0060] Understandably, the support platform 20, the frame 10, and the cutting mechanism 30 can all be part of the cutting equipment, and at least the three of them constitute the cutting equipment.

[0061] After completing the above preparations, the next step will be to cut the board 200, specifically: S42, the plate 200 is cut by cutting the plate segment 220 in the middle of the plate 200.

[0062] Thus, by simultaneously cutting the sheet material 200 with at least two cutting blades 31, each cutting blade 31 has its own cutting segment, cutting length, and cutting area. Compared to using a single cutting blade 31, it eliminates the need to drive the cutting blade 31 to reciprocate along a cutting line, improving cutting efficiency. Furthermore, since the cutting point of the sheet material 200 (i.e., the middle cutting segment 220) is still located at the center of the sheet material 200, cutting with at least one cutting blade 31 ensures that the middle cutting segment 220 is relatively flat compared to the edges. This avoids bouncing during cutting, ensuring cutting accuracy, reducing the production of defective products, and improving the company's efficiency.

[0063] The step of cutting the two edge cutting plate segments 210 along the same cutting line in the X direction using at least two cutting blades 31 includes: Two cutting blades 31 are controlled to cut in the same direction. One cutting blade 31 cuts from the outer end of the edge cutting plate segment 210 toward the middle cutting plate segment 220, and the other cutting blade 31 cuts from the inner end of the other edge cutting plate segment 220 toward the outer end.

[0064] Furthermore, the step of cutting the sheet 200 by cutting the sheet 200 in the middle of the cut section 220 includes: The cutting blade 31, which controls the cutting from the outer end of the edge cutting plate segment 210 toward the middle cutting plate segment 220, continues to cut toward the middle cutting plate segment 220 and cuts the plate 200.

[0065] Thus, one cutting blade 31 cuts from the outer end of one edge cutting segment 210 toward the middle cutting segment 220, while another cutting blade 31 cuts from the inner end of another edge cutting segment 220 toward the outer end. The cutting blade 31 cutting from the outer end of one edge cutting segment 210 toward the middle cutting segment 220 cuts the board 200. In this way, the board 200 is cut by the cooperation of the two cutting blades 31.

[0066] In this embodiment, the relationship between the starting cutting position l1 and L of the cutting blade 31, which cuts from the inner end to the outer end of the edge cutting plate segment 210, is: 0.5LR≤l1≤0.5L+R, where R is the radius of the cutting blade. The outer end of the other uncut edge cutting plate segment 210 is used as the calculation reference point.

[0067] This means that a cutting blade 31 can start cutting at approximately half the length L of the cutting line of the board 200. It can start cutting at a distance R from half the length L of the total cutting line. This avoids the situation where the remaining middle section 220 to be cut is too long after one cutting blade 31 has cut it first, which would affect the cutting effect of the other cutting blade 31 when cutting from the edge to the middle section 220.

[0068] For example, the cutting blade 31 can start cutting from the 0.5LR position, or from the 0.5L position, or from the 0.5L+R position.

[0069] It should be noted that when the board 200 is cut by the two cutting blades 31, the cutting blade 31 that cuts the middle cutting section 220 can start cutting first, and then the other blade can start cutting from the edge of the edge cutting section 210; or the two cutting blades 31 can start cutting at the same time.

[0070] Furthermore, before the step of controlling the cutting blade 31, which is cutting from the outer end of the edge cutting section 210 toward the middle cutting section 220, to continue cutting toward the middle cutting section 220 and cut off the plate 200, the cutting method 400 further includes: Obtain the distance l2 between the cutting point of the cutting blade 31 that cuts from the inner end to the outer end of one edge cutting plate segment 220 along the X direction relative to the cutting point of the plate 200 and the outer end of the other edge cutting plate segment 220 that has not been cut; The spacing l2 is determined to be within a preset range, wherein the preset range of spacing l2 and L is related as follows: 0.5L≤l2≤0.5L+2R; Start another cutting blade 31 to cut from the outer end of the other side cutting plate segment 220 that has not been cut towards the middle cutting plate segment 220, and cut the middle cutting plate segment 220.

[0071] Thus, after the first cutting blade 31 cuts the board 200, the travel position of the first cutting blade 31 is monitored in real time, and it is determined whether the distance between the cutting position of the first cutting blade 31 and the outer end of the uncut edge cutting board segment 220 is within the preset distance range. If so, the other cutting blade 31 is started in time to avoid the first cutting blade 31 cutting to the end point before the other cutting blade 31 is started, which would cause too much waiting time for the other cutting blade 31 and result in low overall productivity.

[0072] Specifically, in this embodiment, the preset range is 0.5L≤l2≤0.5L+2R, meaning that when the first cutting blade 31 travels to the range of 0.5L to 0.5L+2R on the board 200, another cutting blade 31 is started. For example, in one embodiment, when a cutting blade 31b starts cutting from a position close to 0.5LR on the board 200, after traveling a distance R, it reaches the 0.5L position, at which point another cutting blade 31 is started to cut from the outer end of a cutting segment 220 on one side; or in another embodiment, when the cutting blade 31 starts cutting from the 0.5L position on the board 200, after traveling a distance R, it reaches the 0.5L+R position, at which point another cutting blade 31 is started to cut from the outer end of another cutting segment 220 on one side.

[0073] Understandably, after the cutting method of this embodiment is used to cut the board 200, the two cutting blades 31 move to the other side of the board 200, and at this time, the two cutting blades 31 are on the same side of the board 200. At this time, the cutting blade 31 that cuts later can cut the board 200 as if it were the first cutting blade 31. This process is repeated, and the two cutting blades 31 can start the cutting mode on each side of the board 200, saving the time of returning to the initial position and improving the cutting efficiency.

[0074] It should be noted that since the cutting blade 31, which cuts first, starts cutting from the middle of the plate segment 220 of the plate 200, it is initially located above the plate 200 and gradually moves downwards towards the plate 200. Therefore, the cutting mechanism 30 includes not only the cutting drive component 33 that drives the cutting blade 31 to rotate, such as a drive method combining a motor and a reducer, but also the lifting drive component 34 that drives the cutting blade 31 to move up and down, such as using a motor and a lead screw pair to drive the cutting blade 31 to move up and down.

[0075] In another embodiment of the present invention, the step of cutting the two edge cutting plate segments 210 along the same cutting line in the X direction by at least two cutting blades 31 includes: Both cutting blades 31 are controlled to cut in opposite directions from the outer end of the edge cutting plate segment 210 toward the middle cutting plate segment 220.

[0076] In this embodiment, the cutting method involves two cutting blades 31 moving in the same direction to cut the plate 200, and both blades can be started simultaneously to ensure cutting efficiency.

[0077] Furthermore, when two cutting blades 31 are used to cut the plate 200 from the outer end of the edge cutting segment 210 toward the middle cutting segment 220, the step of cutting the plate 200 at the middle cutting segment 220 includes: One of the two cutting blades 31 that control the edge cutting plate segment 210 moves backward after cutting the edge cutting plate segment 210, while the other continues to cut towards the middle cutting plate segment 220 and cuts the plate 200.

[0078] Thus, as the two cutting blades 31 move closer to the middle cutting section 220, in order to avoid interference between the two cutting blades, one of the two cutting blades 31 that cut the edge cutting section 210 is controlled to retreat after cutting the edge cutting section 210, while the other continues to cut towards the middle cutting section 220 and cut the board 200, thereby achieving the effect of cutting the board.

[0079] Understandably, the cutting blade that cuts the board 200 also retracts to the other edge of the board 200 after cutting it, so that the two cutting blades 31 are ready for the next cut.

[0080] When the plate 200 is cut using the above-described cutting method, for ease of explanation, in this embodiment, two cutting blades 31 located on the same cutting line along the X direction are defined as the first cutting blade 31a and the second cutting blade 31b. The plate 200 has two edges of two edge cutting plate segments 210 along the X direction, and the edges of the two edge cutting plate segments 210 of the plate 200 are defined as the first edge 230 and the second edge 240.

[0081] Please see Figure 9 In one embodiment of unidirectional cutting, the first cutting blade 3a1 and the second cutting blade 31b are placed on the same edge of the plate 200, for example, they can be placed on the first edge 230 or the second edge 240; or see [link to relevant documentation]. Figure 10In another embodiment of unidirectional cutting, the first cutting blade 31b is placed corresponding to the middle cutting plate segment 220, and the second cutting blade 31a is placed on one edge of the plate 200, which can be located at the first edge 230 or the second edge 240.

[0082] Understandably, when a cutting blade 31 begins cutting from the middle of the plate 200, cutting segment 220, the cutting blade 31 must first be positioned above the plate 200 to avoid touching it. Once the plate 200 is in the correct position, the cutting blade 31 is gradually lowered and begins cutting from the middle of the plate 200, cutting segment 220. After cutting the plate 200, the blade remains at the same height. Therefore, the cutting mechanism 30 also includes a lifting drive 34 to drive the cutting blade 31 to move up and down.

[0083] In this way, by using two cutting blades 31 to cut the board 200 simultaneously, compared to using one cutting blade 31 to cut the board 200, the cutting method that requires one cutting blade 31 to move back and forth is avoided, thus improving the overall cutting efficiency of the board 200.

[0084] Please see Figure 11 In the same-direction cutting method, the first cutting blade 3a1 and the second cutting blade 31b are placed on the first edge 230 and the second edge 240 of the board 200, respectively. The two cutting blades 31 move towards each other. When they approach the middle cutting segment 220 of the board 200, one cutting blade 31 (for example, it can be the first cutting blade 3a1 or the second cutting blade 31b) retracts to the initial position, and the other cutting blade 31 cuts the middle cutting segment 220 of the board 200. In this way, the board 200 is cut.

[0085] Therefore, in this embodiment, by placing two cutting blades 31 on both sides of the plate 200 to cut the plate 200 simultaneously, the cutting method of this embodiment has higher cutting efficiency than the method of cutting the plate 200 by having one cutting blade 31 move back and forth.

[0086] It should be noted that, in order to ensure that the two cutting blades 31 are always in a collinear state, the straightness detection sensor 80 detects the straightness of the two cutting blades 31 in real time along the X direction during the cutting process. For example, the straightness detection sensor 80 can be set as an infrared sensor. When the infrared light emitted by the infrared sensor on one cutting mechanism 30 can always illuminate the other cutting mechanism 30, it can be ensured that the two cutting blades 31 in the two cutting mechanisms 30 are in a collinear state.

[0087] Optionally, the cutting method 400 further includes: The collinearity of the two cutting blades 31 is determined based on the collinearity signal from the straightness detection sensor 80. If it is determined that the two cutting blades 31 are not collinear, the cutting mechanism is controlled to stop and an alarm signal is issued, or the cutting mechanism is controlled to adjust its position according to the offset position.

[0088] The offset position can be obtained in various ways, such as by a visual recognition device or by setting up a light signal recognition device that can recognize the light signal offset of the straightness detection sensor 80.

[0089] Furthermore, regardless of whether the two cutting blades 31 are used in the same direction or in opposite directions as described above: The rotational speed of the cutting blade 31 is 2000-2400 r / s. This avoids insufficient cutting force due to excessively low rotational speed of the cutting blade 31, which could cause the blade to get stuck in the brick, and also avoids excessive wear on the cutting blade due to excessively high rotational speed.

[0090] The travel speed of the cutting blade 31 is in the range of 2.0-2.8m / min. The width of a piece of board 200 along the X direction is approximately 2.4-2.6m. The travel speed of the cutting blade 31 is equivalent to the width of the board 200, which means that the cutting is completed in 1 minute. This avoids the situation where the travel speed of the cutting blade 31 is too fast and the cutting accuracy of the board 200 is insufficient, which may easily produce rough cutting edges.

[0091] Taking a piece of board 200 with dimensions of 2440*3100*100mm as an example, in the prior art, when cutting with a single cutting blade 31, it can cut approximately 50 pieces per hour; in the two cutting methods described above in this embodiment, which use two cutting blades 31 to cut simultaneously, at least 75 pieces per hour can be cut; if the value of a piece of board 200 is 2000 yuan, the company will generate an additional revenue of 2000*24*(75-50)=1200000 yuan per day, thereby improving the company's efficiency.

[0092] The above-mentioned cutting method 400, by setting two cutting blades 31 to cut the board 200 simultaneously on the same side or both sides of the board 200, saves the time of the cutting blade 31's reciprocating movement compared to the method of using one cutting blade 31 to cut the board 200. More boards 200 can be cut in the same amount of time, resulting in higher production efficiency and improved enterprise benefits.

[0093] The technical means disclosed in this invention are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of this invention, and these improvements and modifications are also considered within the scope of protection of this invention.
