Description

Technical Field

[0001] The present application relates to the technical field of fan bone cutting, and in particular to a fan bone laser cutting device and method thereof. Background Art

[0002] In the traditional bamboo fan processing technology, the fan rib blank needs to be cut into the shape of the fan rib. At present, there are two main methods for cutting fan ribs. One is that the craftsman manually cuts the fan rib blank into the shape of the fan rib using tools such as knives, chisels, etc. However, manual cutting is not only inefficient and difficult to meet the needs of large-scale production, but also requires extremely high skills from the craftsmen, and the shape and quality of the fan ribs may be affected by the slightest carelessness. The other is to use fan rib laser cutting equipment to directly cut the fan rib blank. However, the existing fan rib laser cutting equipment cannot synchronously locate the processing position of the fan rib blank during the process of conveying the fan rib blank. Therefore, when position deviation occurs during the cutting process, it is easy to cause the fan rib shape to be irregular, or defects such as burrs and cracks to appear, affecting the overall quality and aesthetics of the bamboo fan.

[0003] In Chinese patent CN216858656U, a clamping device for a laser cutting machine tool is disclosed, comprising: a quadrilateral frame, grooves are provided on both sides of the inner wall of the quadrilateral frame, a first bidirectional ball screw is rotatably connected in the groove, a mounting shell is provided between the first bidirectional ball screws, two mounting shells are provided and arranged in parallel, a first thread block is fixedly connected at both ends of the mounting shell, the end of the first thread block away from the mounting shell is spirally connected to the first bidirectional ball screw, a guide rail is provided at the top of the mounting shell, and a sliding platform is slidably connected at both ends of the guide rail; a support frame is fixedly connected to the top of the sliding platform, and a clamping claw is rotatably connected between the vertical rods on both sides of the support frame. In the above scheme, although the problem of fixing the fan rib blank is solved to a certain extent; however, since its fixing method mainly focuses on fixing the edge of the bamboo board, the flatness control of the surface of the bamboo board during the cutting process is insufficient. Therefore, in the actual cutting process, due to the lack of stable support on the bottom surface of the bamboo board, the bamboo board may be unevenly bent and deformed under the action of the laser cutting force.

[0004] A laser cutting positioning tool is disclosed in Chinese patent CN11890546B, including: a connecting mechanism and a supporting part installed on a table, a pair of positioning mechanisms are symmetrically provided on the supporting part, the connecting mechanism is used for supporting, connecting and fixing the main components on the supporting part, the supporting part plays a supporting role on the circuit board when the circuit board is cut, and the circuit board can be stably and reliably positioned and clamped through the positioning mechanism, and the carbon powder generated by the cutting can be sucked during the cutting process, thereby improving the cutting effect of the circuit board, and secondly, the components in the supporting part used to support the circuit board can be matched and replaced according to the cutting size of the circuit board, and the setting of the connecting mechanism facilitates such replacement operation. In the above scheme, although the bottom surface of the bamboo board can be firmly supported by the pad in the support part to prevent uneven bending and deformation of the bamboo board under the action of the laser cutting force during the actual cutting process, and the edge of the bamboo board is clamped and fixed by the positioning mechanism; however, if the bamboo board shakes or tilts during the process of being transported by the conveyor belt to the laser cutting positioning tool, even if the bottom surface and edge of the bamboo board are supported and positioned respectively by the pad and the positioning mechanism, the position of the bamboo board before cutting may still be slightly offset due to unstable factors in the transportation process, resulting in irregular shape of the fan ribs, and even defects such as burrs and cracks.

[0005] Therefore, we propose a fan bone laser cutting device here. Summary of the invention

[0011] Preferably, the push assembly comprises a positioning push plate, and the positioning push plate is connected to an external linear drive device.

[0012] Preferably, a plurality of pre-positioning elastic sheets which are distributed at intervals and enable the sash blank to move toward the side of the backing plate are provided on the positioning vertical surface of the positioning push plate.

[0013] Preferably, the width clamping assembly comprises: The first jacking component is used to drive the jacking platform to move up and down; There are a plurality of material clamping fingers, and the material clamping fingers are paired together to form a width clamping space; some of the material clamping fingers are connected to a first translation drive device installed on the jacking platform, and the remaining material clamping fingers are connected to a second translation drive device installed on the jacking platform, and the driving direction of the first translation drive device is opposite to the driving direction of the second translation drive device.

[0015] Preferably, the fan bone laser cutting equipment also includes a stacking silo located on the feeding side of the material conveyor belt; and a fan bone picking robot located above the material positioning mechanism.

[0016] To achieve the above object, the present application also provides a fan bone laser cutting method, using the above fan bone laser cutting device, the fan bone laser cutting method comprises the following steps: S1, stacking the fan rib blanks in a stacking silo; S2, starting the material conveyor belt, and driving the material stoppers (201) evenly distributed on the material conveyor belt to push the fan rib blanks in the stacking bin out of the stacking bin through the forward movement of the material conveyor belt, so that there is one fan rib blank in each fan rib accommodating space; S3, when the sash blanks in S2 enter the laser cutting area, the material conveyor belt stops, and the lifting assembly lifts a number of the sash blanks upward and separates them from the material conveyor belt; the length positioning mechanism positions one end of the material lifted by the lifting assembly in the length direction; the width clamping assembly clamps the sash blanks positioned by the length positioning mechanism in the width direction; S4. A laser cutting mechanism performs laser cutting on the fan rib blank in S3 to obtain a fan rib.

[0017] The beneficial effects of the technical solution of the present invention are: The fan rib blanks are pushed out of the stacking bin by the material conveyor belt and accurately conveyed to the laser cutting area, realizing the automatic feeding process of the materials, improving production efficiency, and reducing the time of manual intervention and material loading and unloading.

[0020] The width clamping assembly uses material clamping fingers that are arranged opposite to each other in pairs, and realizes precise clamping of the fan rib blank in the width direction through the reverse movement of the first translation drive device and the second translation drive device. The stable movement of the material clamping fingers is driven by the translation drive, thereby ensuring the stability and uniformity of the clamping force, ensuring that the fan rib blank will not be displaced due to loose clamping during the cutting process, and improving the flatness and dimensional accuracy of the cutting edge.

[0021] The lifting assembly adopts a design of two parallel lifting plates moving synchronously, which can ensure that the fan rib blanks of different widths can be lifted smoothly. At the same time, the pusher assembly is connected to an external linear drive device, and the pusher speed and force can be adjusted as needed to adapt to fan rib blanks of different thicknesses and materials.

[0026] See also Figure 1-Figure 3 The present invention proposes a fan rib laser cutting device, comprising: a frame 100, a material conveyor belt 200 is fixedly arranged on the frame 100, a plurality of material blocks 201 are evenly distributed on the surface of the material conveyor belt 200, and every two adjacent material blocks 201 form a fan rib accommodating space, which is used to ensure that the fan rib blank is stably placed on the surface of the material conveyor belt 200 during its operation, and ensure that it does not shake or deviate due to the flexibility of the conveyor belt. The fan rib blank has a rectangular structure and is made of bamboo or wood.

[0027] A stacking silo 300 is provided on the feed side of the material conveyor belt 200, which is used to neatly stack the fan rib blanks to be cut on the feed side of the material conveyor belt 200. A dividing mechanism 400 is provided on the discharge side of the material conveyor belt 200. The dividing mechanism 400 has at least one product conveying part 401 and one waste conveying part 402. A material positioning mechanism 500 is provided between the dividing mechanism 400 and the material stacking mechanism 300. A laser cutting mechanism 600 and a fan rib picking robot 4012 are provided above the material positioning mechanism 500.

[0028] The material positioning mechanism 500 includes a lifting assembly 503 for lifting the scallop blanks in a plurality of scallop accommodating spaces upward and away from the material conveyor belt 200, a length positioning mechanism 800 for positioning one end of the scallop blanks lifted by the lifting assembly 503 in the length direction, and a width clamping assembly 502 for clamping the scallop blanks in the width direction after being positioned by the length positioning mechanism 800.

[0029] The laser cutting mechanism 600 comprises at least a plurality of laser cutting heads 6006 corresponding to the fan rib blanks clamped by the width clamping assembly 502. The laser cutting mechanism 600 moves in the XYZ three axes to form laser cutting of the fan rib blanks.

[0030] In this embodiment, the fan rib blanks are pushed out of the stacking bin 300 by the material conveyor belt 200 and accurately conveyed to the laser cutting area, thereby realizing the automatic feeding process of the material, improving the production efficiency, and reducing the time of manual intervention and material loading and unloading. At the same time, the material block 201 on the material conveyor belt 200 forms a fan rib accommodating space to form a stable conveyance for the fan rib blanks. Moreover, the length positioning mechanism 800 and the width clamping assembly 502 have a certain adjustment capability, which can adapt to fan rib blanks of different lengths and widths, and enhance the adaptability of the equipment to products of different specifications.

[0031] The material positioning mechanism quickly and accurately positions and clamps the fan rib blank in three dimensions through the setting of the lifting assembly 503, the length positioning mechanism 800 and the width clamping assembly 502, providing a stable working environment for laser cutting, so that the fan rib blank is firmly fixed in the specified position, reducing the impact of material shaking or vibration on the cutting accuracy. The relative position between the laser cutting head 6006 and the fan rib blank remains constant, so that the laser beam can accurately cut along a predetermined path, improving the cutting quality.

[0032] In summary, the fan rib laser cutting equipment in this embodiment can be closely connected with the upstream and downstream processes. A stacking bin 300 is provided on the feed side, which facilitates the stacking and storage of raw materials, and also facilitates the connection with the previous process (such as the production process of fan rib blanks). On the discharge side, the cut fan ribs can be classified and transported through the product conveying part 401 and the waste conveying part 402 of the sorting mechanism 400, and directly enter the next process (such as subsequent processing, assembly, etc.), realizing the smooth connection of the entire production process and improving the overall efficiency and coordination of the production process.

[0033] Specifically, the material positioning mechanism 500 includes: a first mounting bracket 501, which is fixed on the frame 100 and located below the material conveyor belt 200, and a width clamping assembly 502 and a lifting assembly 503 are fixed on the first mounting bracket 501, and the width clamping assembly 502 and the lifting assembly 503 are spaced apart.

[0034] The width clamping assembly 502 includes: a first lifting member 5021, the first lifting member 5021 is fixedly connected to the first mounting bracket 501, the driving end of the first lifting member 5021 is connected to a lifting platform 5022, and a first translation driving device 5028 and a second translation driving device 5029 are installed on the lifting platform 5022; the first translation driving device 5028 and the second translation driving device 5029 have the same structure, and the driving direction of the first translation driving device 5028 is opposite to the driving direction of the second translation driving device 5029, and the first translation driving device 5028 and the second translation driving device 5029 are connected to the first translation driving device 5028 and the second translation driving device 5029. A plurality of material clamping fingers 5027 are fixedly connected thereto, among which a part are fixedly connected to the first translation drive device 5028, and the remaining part are fixedly connected to the second translation drive device, and the material clamping fingers 5027 in the first translation drive device 5028 and the material clamping fingers 5027 in the second translation drive device are arranged adjacent to each other in pairs, and the material clamping fingers 5027 arranged adjacent to each other in pairs form a width clamping space, so that they move toward or in opposite directions under the drive of the first translation drive device 5028 and the second translation drive device 5029, so as to realize the clamping and fixation of fan rib blanks of different widths.

[0035] The first translation drive device 5028 includes: a translation drive 5023, a driving end of the translation drive 5023 is slidingly provided with a first clamp 5024 and a second clamp 5025, the first clamp 5024 and the second clamp 5025 are arranged opposite to each other, and the second clamp 5025 and the first clamp 5024 are provided with a support drive plate 5026 on the side away from each other, and the support drive plate 5026 is closely connected to the material clamping finger 5027 to provide stable support and precise guiding effect therefor.

[0036] Among them, the first lifting component 5021 can adopt driving components such as cylinders, motors, hydraulic cylinders, etc. to provide lifting force and realize the up and down movement function of the lifting platform 5022; the translation drive 5023 can adopt driving components such as finger cylinders and electric cylinders to adjust the relative positions of the first clamping block 5024 and the second clamping block 5025 to ensure that the fan frame blank is accurately positioned in the width direction.

[0037] Furthermore, when it is necessary to clamp and fix the fan frame blanks of different widths, the first lifting member 5021 moves upward under the action of the driving device, and drives the first translation driving device and the second translation driving device to rise to a suitable height as a whole through the lifting platform 5022.

[0038] As the lifting platform 5022 reaches the predetermined position, the first translation drive device 5028 and the second translation drive device 5029 start to work. Since the first translation drive device 5028 and the second translation drive device 5029 have the same structure but opposite driving directions, they will drive the first clamping block 5024 and the second clamping block 5025 connected thereto to move toward or in the opposite direction. In this process, the driving end of the translation drive 5023 will slide along a specific track, thereby driving the first clamping block 5024 and the second clamping block 5025 to make corresponding movements.

[0039] When the first clamping block 5024 and the second clamping block 5025 move toward each other under the drive of the translation driver 5023, the material clamping fingers 5027 fixed thereon will also move accordingly. Since these material clamping fingers 5027 are arranged along the support driving plate 5026, they will maintain accurate spacing and arrangement during the movement, thereby ensuring that the fan rib blanks of different widths can be evenly and firmly clamped.

[0040] Once the fan rib blank is clamped, the laser cutting mechanism 600 will start to perform precise cutting operations on the clamped fan rib blank. During the cutting process, since the material clamping fingers 5027 provide a stable and reliable clamping force, the fan rib blank will not move or shake, thereby ensuring the accuracy and quality of the cutting.

[0041] After cutting is completed, the first lifting member 5021 will drive the lifting platform 5022 to descend, and at the same time, the first translation drive device 5028 and the second translation drive device 5029 will drive the material clamping finger 5027 to move in the opposite direction, loosening the clamping of the fan rib blank, so as to remove the cut fan rib blank from the clamping assembly for subsequent processing or treatment.

[0042] In one embodiment, there are two material conveyor belts 200 which are parallel to each other, and a receiving space is formed between the two material conveyor belts 200 , and the width clamping assembly 502 is located in the receiving space.

[0043] In this embodiment, the width clamping assembly 502 is arranged reasonably in the accommodation space between the two parallel material conveyor belts 200, so that the structure of the equipment is more compact, thereby reducing the floor space of the equipment and improving the space utilization rate of the production workshop. At the same time, the material conveying, positioning and cutting processes are completed in a relatively concentrated area, which is convenient for operators to monitor and manage.

[0044] See also Figure 4In order to improve the processing efficiency of laser cutting, in another embodiment, one end of the support driving plate 5026 extends toward the side of the frame 100 close to the material dividing mechanism 400 to increase the number of fan rib blanks that the support driving plate 5026 can support at the same time, and a support mechanism 504 is arranged therebelow to ensure that the support driving plate 5026 always remains in a horizontal state during the upward movement.

[0045] The support mechanism 504 includes: a second mounting bracket 5041, the second mounting bracket 5041 is fixedly mounted on one side of the frame 100 close to the material distribution mechanism 400, a third lifting member 5042 is fixedly mounted on the second mounting bracket 5041, and the driving end of the third lifting member 5042 is connected to the support platform 5043, so that the support platform 5043 has the ability of axial lifting and lowering, and the upper surface of the support platform 5043 is provided with a plurality of positioning grooves 5044 corresponding to the support drive plate 5026, and the size and shape of the positioning grooves 5044 match the support drive plate 5026 to ensure that the support drive plate 5026 can be stably placed on the support platform 5043.

[0046] Specifically, when the first lifting member 5021 drives the support driving plate 5026 to rise or fall, the support platform 5043 adjusts its height through the third lifting member 5042 to keep the support driving plate 5026 in a horizontal state.

[0047] Furthermore, in order to ensure the stability of the fan frame blank during the rising process, the length of the support drive plate 5026 is equal to the length of the lifting plate 5033, and a fourth lifting member connected to the lifting plate 5033 is provided on the second mounting bracket 5041 to ensure that the lifting plate 5033 remains horizontal during the rising or falling process.

[0048] Among them, the third lifting component 5042 and the fourth lifting component can both use driving components such as cylinders, motors, hydraulic cylinders, etc. to provide lifting force to achieve the up and down movement function of the supporting platform 5043 and the lifting plate 5033.

[0049] See also Figure 5 In one embodiment, the initial plane of the lifting plate 5033 is higher than the initial plane of the supporting driving plate 5026, the upper end of the lifting plate 5033 is arranged in the form of an elastic cushion layer, and a groove 5045 matching the shape of the fan rib blank is arranged on the upper surface of the lifting plate 5033, and a plurality of suction cups 5046 are evenly distributed inside the groove 5045.

[0050] Specifically, when the fan rib blank is supported above the material conveyor belt 200 by the lifting plate 5033 and the support driving plate 5026, the two adjacent material clamping fingers 5027 are tightly attached to the two sides of the bamboo board under the drive of the translation driver 5023, and the weight of the bamboo board acts on the lifting plate 5033. Since the initial plane of the lifting plate 5033 is higher than the initial plane of the support driving plate 5026, in order to ensure that the lifting plate 5033 and the support driving plate 5026 are always in the same plane during the laser cutting process, thereby providing sufficient plane support for the bamboo board, at this time, the piston rod of the second lifting member 5031 will gradually shrink, thereby driving the lifting plate 5033 to continuously adjust its position in the vertical direction, so that the suction cup 5046 on the elastic cushion layer can be tightly adsorbed on the surface of the bamboo board, further fixing the position of the bamboo board to prevent it from displacement during subsequent processing.

[0051] In one embodiment, the lifting assembly 503 includes: the lifting assembly 503 includes two mutually parallel lifting plates 5033, the lifting plates 5033 are connected to a second lifting component 5031 that drives the lifting plates 5033 to move up and down between the non-lifting position and the lifting position, and the two lifting plates 5033 move synchronously.

[0052] The second lifting member 5031 may also be driven by a cylinder, a motor, a hydraulic cylinder or other driving components to provide a lifting force and realize the up and down movement function of the lifting plate 5033 .

[0053] Specifically, the second lifting member 5031 is fixedly connected to the first mounting bracket 501 and is parallel to the first lifting member 5021 . A connecting shaft 5032 is fixedly disposed at the driving end of the second lifting member 5031 , and a lifting plate 5033 is threadedly connected to the connecting shaft 5032 .

[0054] In another embodiment, the second lifting member 5031 is fixedly connected to the first mounting bracket 501 and is parallel to the first lifting member 5021 . A connecting shaft 5032 is fixedly disposed at the driving end of the second lifting member 5031 , and a lifting rod is threadedly sleeved on the connecting shaft 5032 .

[0055] This embodiment can ensure that the two lifting plates 5033 can maintain a strict parallel state during the movement. At the same time, the existence of the connecting shaft 5032 ensures the stability and synchronization of the lifting plates 5033 during the rising and falling processes, reducing the material shaking or uneven force caused by the tilting or asynchronous movement of the lifting plates. And when the driving end of the second lifting member 5031 drives the connecting shaft 5032, due to the parallel arrangement of the two lifting plates 5033, they can rise or fall simultaneously and evenly, ensuring the smooth lifting of the fan frame blank.

[0056] See also Figure 6-Figure 7In one embodiment, the length positioning mechanism 800 includes a backing plate 700 and a material pushing assembly 8000 that moves linearly on a horizontal plane relative to the backing plate 700, and a material conveying belt 200 is provided between the backing plate 700 and the material pushing assembly 8000. The backing plate 700 and the material pushing assembly 8000 are distributed in the width direction of the material conveying belt 200.

[0057] Specifically, the push assembly 8000 includes: a positioning push plate 8005, and the positioning push plate 8005 is connected to the linear drive device 8006.

[0058] The linear drive device 8006 includes: a frame 8001, which is fixedly arranged on a side of the frame 100 away from the backing plate 700, and a transmission screw 8002 is arranged on the frame 8001, one end of the transmission screw 8002 is rotatably connected to the side wall of the frame 100, and its axis is perpendicular to the material conveying direction, the other end of the transmission screw 8002 passes through the frame 8001 and extends outward, and the end of the transmission screw 8002 extending to the outside of the frame 8001 is transmission-connected with a driving mechanism for driving the transmission screw 8002 to rotate, and a screw nut 8003 is threadedly connected to the middle part of the transmission screw 8002, and a movable plate 8004 is fixedly arranged on the screw nut 8003, and the movable plate 8004 is fixedly connected to the positioning push plate 8005.

[0059] The driving mechanism may be a motor, which is connected to the transmission screw 8002 by a pulley drive or a direct drive to provide rotational power. When the fan rib blank needs to be fine-tuned in the length direction, the motor is started, and the screw nut 8003 is driven to move along the material conveying direction through the rotation of the transmission screw 8002, so that the positioning push plate 8005 fixed on the moving plate 8004 can accurately adjust the position of the bamboo board.

[0060] Furthermore, for those skilled in the art, the manner in which the motor drives the transmission screw 8002 to rotate is a conventional technique and is therefore not shown in the accompanying drawings.

[0061] In this embodiment, the backing plate 700 fixed on the side wall of the frame 100 is used as a reference surface on one side of the bamboo board to further ensure that the bamboo board is accurately positioned in the width direction and avoid its left and right deviation. Then, the driving mechanism in the length positioning mechanism 800, that is, the motor (not shown in the figure) is started. The motor is connected to the transmission screw 8002 by a pulley drive or a direct drive method to provide a rotational power for the transmission screw. At the same time, as the motor rotates, the transmission screw 8002 starts to rotate. Since one end of the transmission screw 8002 is rotatably connected to the side wall of the frame 100, and its axis is perpendicular to the material conveying direction, the rotation of the transmission screw will drive the screw nut 8003 at the other end thereof to move along the material conveying direction, and then the movement of the screw nut 8003 will drive the movable plate 8004 fixed thereon to move together. Since the positioning push plate 8005 is fixedly connected to the movable plate 8004, the positioning push plate will also move with the movable plate, thereby achieving fine-tuning of the fan rib blank in the length direction to ensure that the bamboo board will not affect the cutting accuracy due to shaking or deviation during the laser cutting process.

[0062] Furthermore, a guide rod (not shown in the figure) is provided inside the frame 8001. The guide rod is parallel to the transmission screw 8002, and its two ends are respectively fixedly connected to the two side walls of the frame 8001, and a through hole for the guide rod to pass through is provided on the screw nut 8003, so that the screw nut 8003 can always slide smoothly along the direction of the guide rod during the process of moving along the axial direction of the screw, thereby improving the stability and accuracy of the movement of the positioning push plate 8005 and ensuring the accuracy and reliability of length positioning.

[0063] In one of the embodiments, a plurality of pre-positioning elastic plates 8007 are provided on the positioning vertical surface of the positioning push plate 8005 and are distributed at intervals so as to move the sash blank toward the side of the backing plate 700.

[0064] Among them, the pre-positioning and shifting elastic piece 8007 is arranged in an arc-shaped structure, one end of the pre-positioning and shifting elastic piece 8007 is fixed on the inner wall of the frame 8001, and the other end extends slightly toward the direction of the material conveyor belt 200.

[0065] Specifically, when the fan rib blank is conveyed to the position of the pre-positioning and shifting elastic piece 8007 on the material conveyor belt 200, the pre-positioning and shifting elastic piece 8007 can smoothly contact the side of the bamboo board due to its arc-shaped structure design. At the same time, at the moment when the pre-positioning and shifting elastic piece 8007 contacts the bamboo board, the pre-positioning and shifting elastic piece 8007 is squeezed by the bamboo board and elastically deformed, thereby generating an elastic force pointing to the outside of the material conveyor belt 200, and the direction of the elastic force is perpendicular to the movement direction of the bamboo board on the material conveyor belt 200.

[0066] The setting of the pre-positioning and moving elastic sheet 8007 in the present embodiment can effectively reduce the shaking of the bamboo board during the conveying process, especially when the speed of the material conveyor belt 200 is fast or the bamboo board is heavy, the pre-positioning and moving elastic sheet 8007 can play a guiding and stabilizing role to prevent the bamboo board from colliding with other components or deviating from the conveying path due to shaking; and when the fan rib blank passes through the pre-positioning and moving elastic sheet 8007 during the conveying process, the pre-positioning and moving elastic sheet 8007 can gently move the bamboo board to ensure that it moves forward stably along the material conveying direction.

[0067] Furthermore, a sensor assembly is provided on the frame 100 between the backing plate 700 and the length positioning mechanism 800, and the sensor assembly includes: a laser displacement sensor and a proximity switch. The laser displacement sensor is installed on the frame 8001, and its transmitting end faces the upper surface of the fan rib blank, and is used to monitor the position information of the bamboo board in the height direction in real time; the proximity switch is installed on the frame 100, located below the material conveyor belt 200, and is used to detect whether the material has reached the processing area.

[0068] Specifically, when the fan rib blank is initially positioned and conveyed to the detection range of the proximity switch, the proximity switch sends a signal, triggering the control system to start the material positioning mechanism 500 to fine-tune the height of the bamboo board. At the same time, the laser displacement sensor transmits the real-time monitored bamboo board height data to the control system, and performs fine-tuning positioning operations by controlling the length positioning mechanism 800, further ensuring the precise positioning of the fan rib blank in three-dimensional space.

[0069] Among them, the laser displacement sensor can be set up with Omron ZX-LD60, which uses the reflection principle of the laser beam to analyze the time difference or phase difference of the reflected light to determine the distance of the object; the proximity switch can be set up with Autonics PR12-11DN. When the object blocks the light, the resistance value of the photosensitive element will change, thereby triggering the switch action.

[0070] Further, for those skilled in the art, using a sensor assembly to detect the position information of the bamboo board is a conventional technique, and therefore, it is not shown in the accompanying drawings.

[0071] In another embodiment, a camera assembly (not shown) may be provided on the frame 100, and the camera assembly works in conjunction with the sensor assembly to capture the position and state image of the fan rib blank in real time. Through image processing and analysis technology, the control system can be further assisted to realize the precise positioning and cutting operation of the fan rib blank.

[0072] Specifically, the camera assembly can be installed on the frame 8001 or the laser cutting mechanism 600, and its shooting direction is facing the fan rib blank on the material conveyor belt 200. When the fan rib blank is initially positioned and conveyed to the shooting range of the camera assembly, the camera assembly will capture the position and state images of the bamboo board in real time, and transmit these image data to the control system. The control system can accurately identify the position and posture information of the fan rib blank by processing and analyzing the image data, and fuse it with the data monitored by the sensor assembly, thereby further ensuring the precise positioning of the fan rib blank in three-dimensional space.

[0074] In this embodiment, by setting the cantilever 6002, the laser cutting head 6006 can be stably located above the material conveyor belt 200 and can be quickly and accurately moved to the desired cutting position, reducing the preparation work before cutting and the adjustment time during the cutting process, thereby improving the overall cutting efficiency.

[0075] The arrangement of the first moving part 6003 and the second moving part 6004 enables the third moving part 6005 and the laser cutting head 6006 to be precisely adjusted in the direction perpendicular to the material conveying direction (Y axis) and along the material conveying direction (X axis), so that the laser cutting head 6006 can be accurately aligned with different parts of the fan rib blank to meet the cutting requirements of different sizes and shapes. At the same time, the third moving part 6005 enables the laser cutting head 6006 to have the ability of axial lifting (Z axis), so that the focal length between the laser cutting head 6006 and the fan rib blank can be precisely adjusted according to different thicknesses and cutting requirements.

[0076] The first moving part 6003 and the second moving part 6004 can be provided by driving components such as a linear guide rail system, a ball screw pair, and a pneumatic slide; the third moving part 6005 can be provided by driving components such as a cylinder, a motor, and a hydraulic cylinder.

[0078] On the one hand, the present embodiment fixes the mounting frame 4011 above the cantilever 6002, providing a stable support structure for the rib picking manipulator 4012. At the same time, the product conveyor belt 4013 is provided so that after the rib suction cup 4016 grabs the bamboo board, the bamboo board can be stably conveyed to the cutting area through the operation of the conveyor belt, thereby reducing the shaking or deviation of the bamboo board caused by manual operation or unstable conveying; On the other hand, the fan rib picking robot 4012 adopts a design of sliding cooperation between the sliding plate 4014 and the mounting frame 4011, so that the fan rib suction cup 4016 can move quickly and accurately along the material conveying direction (i.e. the conveying direction of the fan rib blank), thereby ensuring that the fan rib suction cup 4016 can quickly and accurately locate and adsorb the bamboo board before the bamboo board reaches the cutting position, thereby improving the grasping efficiency and reducing scratches or damage to the surface of the bamboo board caused by collision or friction, thereby ensuring the quality of the bamboo board after cutting.

[0079] See also Fig. 9 In one embodiment, the waste conveying unit 402 includes: a waste collection box 4021, and the waste collection box 4021 is fixedly installed under the product conveyor belt 4013.

[0080] In this embodiment, the waste collection box 4021 is directly fixed under the product conveyor belt 4013, so that the waste generated during the bamboo board cutting process can fall directly and quickly into the collection box, utilizing the effect of gravity, simplifying the waste collection process and improving the efficiency of waste treatment.
