Description

Technical Field

[0001] The invention relates to the field of cutting technology, in particular to laser seamless tracking cutting equipment and a cutting method thereof. Background Art

[0002] As a commonly used decoration material, decorative panels can be made by pasting fabrics on plywood. In order to improve the processing efficiency of decorative panels, currently, rolled fabrics are generally pasted on multiple plywoods in a production line continuously, so that every two adjacent plywoods are connected together by the fabrics, and in subsequent processing, the fabrics between the two plywoods need to be cut to separate the decorative panels.

[0003] At present, the fabric cutting generally adopts the suspended cutting scheme, that is, the cutting device is fixed at a certain position, and when the seam between two plywood boards just passes through the cutting device, the conveyor line stops running, and then the cutting device cuts the fabric on the seam to separate the decorative board. However, since the above cutting scheme requires the board to be suspended, its processing efficiency is low, and in order to reserve a certain cutting tolerance, the seam between the two plywood boards is larger, resulting in waste of fabric, resulting in the need for secondary trimming of the remaining material in subsequent processes. Summary of the invention

[0004] The invention aims to provide a laser seamless tracking cutting device to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0005] The laser seamless tracking cutting device according to the first embodiment of the present invention comprises:

[0006] A conveyor, which is provided with two mounting frames, and the conveyor is provided with a conveying line for forward conveying between the two mounting frames;

[0007] A laser tracking and cutting module is installed on the installation frame and is located above the conveyor line. The laser tracking and cutting module includes a front-to-back moving mechanism, a left-to-right moving mechanism and a laser cutting mechanism. The laser cutting mechanism is provided with a laser cutting head arranged downward. The front-to-back moving mechanism is electrically driven to have a first moving block that can move forward and backward. The left-to-right moving mechanism is installed on the first moving block. The left-to-right moving mechanism is electrically driven to have a second moving block that can move left-to-right. The laser cutting head is installed on the second moving block. The laser cutting head has a starting origin.

[0008] A detection switch is installed on the installation frame and located behind the starting origin. The detection switch is used to detect the plate seam between two adjacent plates on the conveyor line. The detection switch is connected to the laser tracking cutting module by electrical signals.

[0009] The laser seamless tracking cutting equipment according to the embodiment of the invention has at least the following beneficial effects: the conveyor line conveys the sheet material forward, and when the detection switch detects the plate seam between two adjacent sheets on the conveyor line, the detection switch activates the laser tracking cutting module. After a period of time, the laser cutting head can simultaneously move along the path of the plate seam and cut the fabric on the plate seam under the drive of the front and rear moving mechanism and the left and right moving mechanism. At this time, the laser cutting head moves along the oblique line to achieve tracking cutting of the plate seam fabric without stopping the conveyor line. The processing efficiency is much higher than that of the prior art solution. Moreover, since the laser cutting head can track the plate seam for cutting, every two adjacent sheets can be conveyed close to each other to achieve a seamless cutting effect, thereby reducing waste of fabric and eliminating the need for secondary trimming of excess material.

[0010] According to some embodiments created by the present invention, in order to ensure that the fabric can completely cover the sheet material, the size of the fabric is generally slightly larger than the size of the sheet material, which will cause part of the fabric to extend beyond the left and right edges of the sheet material. In order to cut off the left and right excess material of the sheet material, the laser seamless tracking cutting device also includes a trimming mechanism, which is installed on the installation frame and located behind the detection switch. The trimming mechanism is provided with a trimming part, which is located between the conveyor line and the installation frame to achieve the cutting of the left and right excess material of the sheet material. When the left and right excess material of the sheet material is removed, the detection switch will no longer be blocked by the excess material and affect its accuracy in detecting the plate seam, thereby effectively improving the cutting accuracy of the laser seamless tracking cutting device.

[0011] According to some embodiments created by the present invention, the trimming mechanism also includes a fixed plate, a movable frame and an elastic telescopic part, the fixed plate is fixedly connected to the mounting frame, the movable frame is slidably connected to the fixed plate left and right, the trimming part is installed on the movable frame, the movable frame and the fixed plate are elastically connected through the elastic telescopic part, so that the trimming part can cut the excess material along the left and right edges of the sheet material, thereby preventing the sheet material from being cut by the trimming part.

[0012] According to some embodiments of the present invention, the movable frame is also connected to a roller, and the roller is located between the conveyor line and the installation frame, and the roller is used to prevent the sheet material from deviating during the conveying process.

[0013] According to some embodiments of the present invention, the mounting frame is connected to a material receiving tray below the trimming portion, and the material receiving tray is used to collect the cut-off residual materials.

[0014] According to some embodiments of the invention, the laser tracking cutting module further includes a front fixing seat and a rear fixing seat, both of which are mounted on the two mounting frames and span the top of the conveyor line, and the laser cutting mechanism further includes a laser generator and a reflection component, the laser generator is mounted on any one of the front fixing seat and the rear fixing seat, and the reflection component is used to reflect the laser generated by the laser generator to the laser cutting head. Through the above arrangement, the laser generator can be fixed in a certain place to avoid damage due to bumps.

[0015] According to some embodiments created by the present invention, in order to realize the movement of the laser cutting head, the front-to-back moving mechanism includes a first motor, a transmission assembly and two first synchronous belt pulley transmission mechanisms, the first motor is connected to any one of the front fixed seat and the rear fixed seat, the two first synchronous belt pulley transmission mechanisms are respectively connected to the two mounting frames, the first motor and the two first synchronous belt pulley transmission mechanisms are connected through the transmission assembly, and each of the first synchronous belt pulley transmission mechanisms is connected to the first moving block; the left-right moving mechanism includes a second motor and a second synchronous belt pulley transmission mechanism, the left and right ends of the second synchronous belt pulley transmission mechanism are respectively connected to the two first moving blocks, the second motor is connected to the second synchronous belt pulley transmission mechanism, and the second synchronous belt pulley transmission mechanism is connected to the second moving block.

[0016] According to some embodiments of the invention, an exhaust pipe is connected between the front fixing seat and the rear fixing seat, and first flip doors are hinged on both sides of the exhaust pipe. The front fixing seat, the rear fixing seat, the exhaust pipe and the first flip door together form an outer cover, and the moving range of the laser cutting head is within the outer cover. When the exhaust pipe is connected to an exhaust fan, the exhaust fan can absorb the waste after cutting to prevent the waste from remaining on the decorative plate.

[0017] According to some embodiments of the present invention, since photoelectric switches have the advantages of wide detection range and high sensitivity, the detection switch is a photoelectric switch.

[0018] A cutting method according to a second aspect of an embodiment of the present invention includes the above-mentioned laser seamless tracking cutting device, and further includes the following steps:

[0019] S10, the laser cutting head moves to the starting origin driven by the front-back moving mechanism and the left-right moving mechanism;

[0020] S20, the conveyor line conveys the sheet material forward, and when the detection switch detects the plate seam between two adjacent sheets on the conveyor line, the detection switch feeds back a signal to the controller, and the controller obtains the time interval required for the plate seam to reach the starting origin by calculating relevant parameters. After the time interval, the controller controls the laser tracking and cutting module, so that the laser cutting head can simultaneously move along the path of the plate seam under the drive of the front-rear moving mechanism and the left-right moving mechanism and cut the fabric on the plate seam to separate the decorative panel;

[0021] S30, before the detection switch detects the next plate seam, the laser cutting head moves back to the starting origin driven by the front-back moving mechanism and the left-right moving mechanism.

[0022] A cutting method according to an embodiment of the present invention has at least the following beneficial effects: because the laser cutting head moves back to the starting origin driven by the front-rear moving mechanism and the left-right moving mechanism before the detection switch detects the next plate seam, the present invention can continuously cut the fabric on each plate seam while maintaining a certain conveying rhythm for the plate material.

[0035] like Figure 3 and Figure 4As shown, the laser seamless tracking cutting equipment according to the first embodiment of the invention includes a conveyor 100, a laser tracking cutting module 200 and a detection switch (not shown in the drawings). The conveyor 100 is a prior art, which is provided with a mounting frame 110. The left and right ends of the mounting frame 110 are both parallel mounting frames 111. The conveyor 100 is provided with a forward conveying conveying line 120 between the two mounting frames 111. The conveyor line 120 can be optionally a belt transmission mechanism driven by a conveying motor 121 to realize the forward conveying of multiple sheets 400.

[0036] In addition, the laser tracking cutting module 200 includes a front fixed seat 210, a rear fixed seat 220, a front and rear moving mechanism 230, a left and right moving mechanism 240 and a laser cutting mechanism 250. The front fixed seat 210 and the rear fixed seat 220 are both installed on the two installation frames 111 and span above the conveyor line 120. The front fixed seat 210 and the rear fixed seat 220 are arranged with a front and rear interval. The front fixed seat 210 and the rear fixed seat 220 are both provided with an installation chamber 211 and a second flip door 212 for closing the installation chamber 211. The front-to-back moving mechanism 230 includes a first motor 231, a transmission assembly 232, two first synchronous belt pulley transmission mechanisms 233 and two first moving blocks 234, the first motor 231 is connected to any one of the front fixed seat 210 and the rear fixed seat 220, the two first synchronous belt pulley transmission mechanisms 233 are respectively connected to the two mounting frames 111, the first motor 231 is located between the two first synchronous belt pulley transmission mechanisms 233, the first motor 231 and the two first synchronous belt pulley transmission mechanisms 233 are connected to each other through the transmission assembly 232, so that the first motor 231 can drive the two first synchronous belt pulley transmission mechanisms 233 at the same time, and each of the first synchronous belt pulley transmission mechanisms 233 is connected to the first moving block 234 to realize the front-to-back movement of the two first moving blocks 234. The left-right moving mechanism 240 includes a second motor (not shown in the drawings) and a second synchronous belt pulley transmission mechanism 242, the left and right ends of the second synchronous belt pulley transmission mechanism 242 are respectively connected to the two first moving blocks 234, the second motor is connected to the second synchronous belt pulley transmission mechanism 242, and the second synchronous belt pulley transmission mechanism 242 is connected to the second moving block 243 to realize the left-right movement of the second moving block 243.

[0037] At the same time, the laser cutting mechanism 250 includes a laser generator 251, a reflective component 252 and a laser cutting head 253. The laser cutting head 253 is arranged downward and is installed on the second moving block 243, so that the laser cutting head 253 can be translated along the plane under the drive of the front and rear moving mechanism 230 and the left and right moving mechanism 240. At this time, the laser cutting head 253 has a starting origin. In order to ensure the normal use of the laser generator 251, the laser generator 251 is installed in the installation chamber 211 of the front fixing seat 210 or the installation chamber 211 of the rear fixing seat 220. At this time, the position of the laser generator 251 is fixed and free from bumps. The reflective component 252 includes a plurality of reflectors, which are used to reflect the laser generated by the laser generator 251 to the laser cutting head 253, so that the laser cutting head 253 can emit the laser for cutting the fabric downward. It should be noted that the conveying motor 121, the first motor 231 and the second motor may be selected as servo motors to improve the cutting accuracy of the laser seamless tracking cutting equipment.

[0038] Furthermore, in order to prevent the laser cutting head 253 from overheating, the laser cutting head 253 is also connected to an air blowing pipe 254 to achieve air cooling.

[0039] In order to accurately cut the fabric on the board seam, the detection switch can be optionally a photoelectric switch, which is installed on the installation frame 111 and located behind the starting origin. The detection direction of the detection switch points to the left edge or right edge of the sheet 400. The detection switch is used to detect the board seam between two adjacent sheets 400 on the conveyor line 120. The detection switch is electrically connected to the laser tracking cutting module 200. The conveyor line 120 conveys the sheet material 400 forward. When the detection switch detects the plate seam between two adjacent sheets 400 on the conveyor line 120, the detection switch activates the laser tracking and cutting module 200. After a period of time, the laser cutting head 253 can move along the path of the plate seam and cut the fabric on the plate seam under the drive of the front and rear moving mechanism 230 and the left and right moving mechanism 240 at the same time. At this time, the laser cutting head 253 moves along the oblique line to achieve tracking cutting of the plate seam fabric without stopping the conveyor line 120. The processing efficiency is much higher than that of the existing technical solutions. Moreover, since the laser cutting head 253 can track the plate seam for cutting, every two adjacent sheets 400 can be conveyed closely to achieve a seamless cutting effect, thereby reducing the waste of fabric and eliminating the need for secondary trimming of excess material.

[0040] In order to ensure that the fabric can completely cover the panel 400, the size of the fabric is generally slightly larger than the size of the panel 400, which will cause part of the fabric to extend beyond the left and right edges of the panel 400. Figure 2 and Figure 5 As shown, in order to cut off the left and right excess materials of the sheet material 400, the laser seamless tracking cutting device also includes a trimming mechanism 300, which is installed on the installation frame 111 and is located behind the detection switch. The trimming mechanism 300 includes a fixed plate 310, a movable frame 320, an elastic telescopic portion 330, a trimming portion 340 and a roller 350. The fixed plate 310 is fixedly connected to the installation frame 111, the movable frame 320 is slidably connected to the fixed plate 310, and the trimming portion 340 and the roller 350 are connected to the fixed plate 310. The trimming part 340 and the roller 350 are both installed on the movable frame 320. At this time, the trimming part 340 and the roller 350 are both located between the conveying line 120 and the mounting frame 111. The movable frame 320 and the fixed plate 310 are elastically connected through the elastic telescopic part 330, so that the trimming part 340 can cut the residual material along the left and right edges of the sheet 400, thereby preventing the sheet 400 from being cut by the trimming part 340, and the roller 350 is used to abut against the sheet 400 to prevent the sheet 400 from deviating during the conveying process. In this embodiment, the elastic telescopic part 330 can be selected as a guide column with a spring, and the trimming part 340 can be selected as a cutting knife with a cutting edge facing backwards, but in other embodiments, the trimming part 340 can still be selected as a laser cutter. When the left and right excess materials of the plate 400 are removed, the detection switch will no longer be blocked by the excess materials and affect the accuracy of detecting the plate seam, thereby effectively improving the cutting accuracy of the laser seamless tracking cutting device.

[0041] Furthermore, in order to collect the cut-off residual materials, the mounting frame 111 is connected to a receiving tray 360 below the trimming portion 340 .

[0042] like Figure 1 As shown, in some embodiments of the invention, an exhaust pipe 260 is connected between the front fixing seat 210 and the rear fixing seat 220, and the left and right sides of the exhaust pipe 260 are hinged with first flip doors 270. The front fixing seat 210, the rear fixing seat 220, the exhaust pipe 260 and the first flip door 270 together form an outer cover 201, and the moving range of the laser cutting head 253 is within the outer cover 201. When the exhaust pipe 260 is connected to an exhaust fan (not shown in the drawings), the exhaust fan can absorb the waste after cutting to prevent the waste from remaining on the decorative plate.

[0043] Further, to facilitate the maintenance of the laser tracking cutting module 200, support rods 271 are connected to both the front fixing base 210 and the rear fixing base 220, and support holes (not shown in the drawings) through which the support rods 271 can pass are connected to both the first flip doors 270, so that when the first flip doors 270 are opened, they can maintain their open states under the action of the support rods 271 and the support holes.

[0044] A cutting method according to the second aspect embodiment of the present invention includes the laser seamless tracking cutting device according to the first aspect embodiment of the present invention, and further includes the following steps:

[0045] S10. The laser cutting head 253 moves to the starting origin under the drive of the front-back moving mechanism 230 and the left-right moving mechanism 240.

[0046] S20. The conveyor line 120 conveys the sheet material 400 forward. When the detection switch detects the seam between two adjacent sheet materials 400 on the conveyor line 120, the detection switch feeds back a signal to the controller (not shown in the drawings). After calculating relevant parameters, the controller obtains the time interval required for the seam to reach the starting origin. After this time interval, the controller controls the laser tracking cutting module 200, so that the laser cutting head 253 can move along the path of the seam and cut the fabric on the seam under the drive of the front-back moving mechanism 230 and the left-right moving mechanism 240 at the same time, so as to separate the decorative board.

[0047] S30. Before the detection switch detects the next seam, the laser cutting head 253 moves back to the starting origin under the drive of the front-back moving mechanism 230 and the left-right moving mechanism 240, so that the present invention can continuously cut the fabric on each seam while maintaining a certain conveying rhythm for the sheet material 400.

[0048] To quantify the moving speeds of the laser cutting head 253 in two directions, assume that the length of each sheet material 400 in the front-back direction and the length in the left-right direction are X meters and Y meters respectively, and the conveying speed of the conveyor line 120 is V1 meters per second. At this time, the conveying time T1 of each sheet material 400 = X / V1 seconds. Assume that the cutting time of the laser cutting head 253 is T2, and the moving distance of the first moving block 234 is S. Considering that the laser cutting head 253 needs to reset to the starting origin and perform the next cutting, so T2 < T1 / 2, and S < X / 2. At this time, the moving speed V2 of the second moving block 243 = Y / T2, and the moving speed V3 of the first moving block 234 = S / T2. In this embodiment, V3 = V1.

[0049] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
