Description

Technical Field

[0001] This application relates to the field of fan rib cutting technology, and in particular to a fan rib laser cutting device and its processing method. Background Technology

[0002] In traditional bamboo fan manufacturing, the fan rib blank needs to be cut into the desired shape. Currently, there are two main methods for cutting fan ribs. One method involves craftsmen manually cutting the blank using tools such as knives and chisels. However, manual cutting is not only inefficient and difficult to meet the needs of large-scale production, but also requires extremely high skill levels from the craftsmen; even slight mistakes can affect the shape and quality of the fan ribs. The other method involves using laser cutting equipment to directly cut the fan rib blank. However, existing laser cutting equipment cannot simultaneously position the fan rib blank during the feeding process. Therefore, when positional deviations occur during cutting, it can easily lead to irregular fan rib shapes, or defects such as burrs and cracks, affecting the overall quality and aesthetics of the bamboo fan.

[0003] Chinese patent CN216858656U discloses a clamping device for a laser cutting machine tool, comprising: a quadrilateral frame, with grooves on both sides of the inner wall of the quadrilateral frame; a first bidirectional ball screw rotatably connected within the grooves; two mounting shells arranged parallel to each other between the first bidirectional ball screws; a first threaded block fixedly connected to each end of each mounting shell; the end of each threaded block furthest from the mounting shell being helically connected to the first bidirectional ball screw; a guide rail on the top of each mounting shell; a sliding platform slidably connected to each end of the guide rail; a support frame fixedly connected to the top of the sliding platform; and pawls rotatably connected between the vertical rods on both sides of the support frame. While this solution addresses the problem of fixing rectangular bamboo boards to some extent, its method primarily focuses on fixing the edges of the bamboo board, neglecting to adequately control the flatness of the bamboo board surface during cutting. Therefore, in actual cutting, the lack of stable support on the bottom surface of the bamboo board may lead to uneven bending and deformation under the laser cutting force.

[0004] Chinese patent CN202411398916.7 discloses a laser cutting positioning tool, comprising: a connecting mechanism and a support part mounted on a table; a pair of positioning mechanisms symmetrically arranged on the support part; the connecting mechanism for supporting and fixing the main components on the support part; the support part supports the circuit board during circuit board cutting; and the positioning mechanism can stably and reliably position and clamp the circuit board; during the cutting process, it can also suck up the carbon powder generated during cutting, thereby improving the cutting effect of the circuit board; furthermore, the components in the support part used to support the circuit board can be replaced according to the cutting size of the circuit board, and the setting of the connecting mechanism facilitates such replacement operation. In the above solution, although the bottom surface of the bamboo board can be stably supported by the pad in the support part to avoid uneven bending and deformation of the bamboo board under the action of laser cutting force during the actual cutting process, and the edge of the bamboo board can be clamped and fixed by the positioning mechanism, 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 by the pad and the positioning mechanism respectively, the unstable factors in the transportation process may still cause the position of the bamboo board to shift slightly before cutting, resulting in irregular fan rib shape, or even defects such as burrs and cracks.

[0005] Therefore, we propose a fan-shaped laser cutting device. Utility Model Content

[0006] The main objective of this application is to provide a fan rib laser cutting device, which aims to solve the problems in the prior art that it is impossible to simultaneously position the processing position of the fan rib blank during the feeding process; and that inaccurate positioning leads to positional deviations during the cutting process, resulting in an irregular shape of the fan rib.

[0007] To achieve the above objectives, this application provides a fan rib laser cutting device, comprising: a frame, and the fan rib laser cutting device further comprising:

[0008] A material conveyor belt is mounted on the frame. Several material blocks are evenly distributed on the surface of the material conveyor belt, and each pair of adjacent material blocks forms a fan-shaped rib receiving space.

[0009] A material positioning mechanism is provided on the frame; the material positioning mechanism includes a lifting assembly for lifting the fan bone blanks in the fan bone receiving space upward and separating them from the material conveyor belt, a length positioning mechanism for positioning one end of the fan bone blanks after being lifted by the lifting assembly in the length direction, and a width clamping assembly for clamping the fan bone blanks after being positioned by the length positioning mechanism in the width direction.

[0010] The laser cutting mechanism includes at least a plurality of laser cutting heads that correspond one-to-one with the fan-shaped blanks clamped by the width clamping assembly.

[0011] Preferably, there are two material conveyor belts that are parallel to each other, and a receiving space is formed between the two material conveyor belts, with the width clamping assembly located within the receiving space.

[0012] Preferably, the lifting assembly includes two parallel lifting plates, the lifting plates are connected to a second lifting member that drives the lifting plates to move up and down between the unlifted position and the lifted position, and the two lifting plates move synchronously.

[0013] Preferably, the length positioning mechanism includes a backing plate and a pushing assembly that moves linearly relative to the backing plate on a horizontal plane, and the material conveyor belt is provided between the backing plate and the pushing assembly.

[0014] Preferably, the pushing assembly includes a positioning pusher plate, which is connected to an external linear drive device.

[0015] Preferably, the positioning surface of the positioning push plate is provided with a plurality of pre-positioning actuating elastic pieces that are spaced apart and cause the fan rib blank to move toward the backing plate side.

[0016] Preferably, the width clamping assembly includes:

[0017] The first lifting component is used to drive the lifting platform to move up and down.

[0018] The material clamping fingers are a plurality of each other, and two of the material clamping fingers form a width clamping space; some of the material clamping fingers are connected to a first translation drive device installed on the lifting platform, and the remaining material clamping fingers are connected to a second translation drive device installed on the lifting platform, wherein the driving directions of the first translation drive device and the second translation drive device are opposite.

[0019] Preferably, the structure of the first translation drive device is the same as that of the second translation drive device, including a support drive plate, the material clamping finger is fixed on the corresponding support drive plate, and a translation driver connected to the support drive plate is provided on the lifting platform.

[0020] Preferably, the fan bone laser cutting equipment further includes a palletizing bin located on the feeding side of the material conveyor belt; and a fan bone picking robot located above the material positioning mechanism.

[0021] Preferably, one end of the prepositioning actuating elastic piece is fixed, while the other end is free.

[0022] To achieve the above objectives, this application also provides a processing method for a fan rib laser cutting device, using the aforementioned fan rib laser cutting device, the fan rib laser cutting method comprising the following steps:

[0023] S1. Stack the fan-shaped blanks in the stacking bin;

[0024] S2. Start the material conveyor belt. The forward movement of the material conveyor belt drives the material blocks (201) evenly distributed on it to push the fan bone blanks in the stacking bin out of the stacking bin, so that there is one fan bone blank in each fan bone accommodating space.

[0025] S3. When the fan-shaped blank in S2 enters the laser cutting area, the material conveyor belt stops, and the lifting assembly lifts several fan-shaped blanks upward and removes them from the material conveyor belt; the length positioning mechanism positions one end of the material after it has been lifted by the lifting assembly in the length direction; the width clamping assembly clamps the fan-shaped blank after it has been positioned by the length positioning mechanism in the width direction.

[0026] S4. The laser cutting mechanism performs laser cutting on the fan rib blank in S3 to obtain the fan rib.

[0027] The beneficial effects of this utility model's technical solution are as follows:

[0028] The fan-shaped blanks are pushed out of the palletizing hopper by a material conveyor belt and precisely transported to the laser cutting area, realizing an automated material feeding process, improving production efficiency, and reducing manual intervention and material loading and unloading time. Simultaneously, the material stops on the conveyor belt form a fan-shaped blank receiving space that can accommodate fan-shaped blanks of different widths. Furthermore, the length positioning mechanism and width clamping assembly have a certain degree of adjustability, accommodating fan-shaped blanks of different lengths and widths, enhancing the equipment's adaptability to different product specifications.

[0029] The material positioning mechanism, through the setup of lifting components, length positioning mechanisms, and width clamping components, quickly and accurately positions and clamps the fan rib blank in the X, Y, and Z three-dimensional directions. This provides a stable working environment for laser cutting, ensuring the fan rib blank is firmly fixed in the designated position and reducing the impact of material shaking or vibration on cutting accuracy. The relative position between the laser cutting head and the fan rib blank remains constant, allowing the laser beam to precisely cut along a predetermined path, thus improving cutting quality.

[0030] The length positioning mechanism, through the cooperation of the support plate and the pusher assembly, can accurately position one end of the fan rib blank along its length. The support plate provides a stable positioning reference, while the pusher assembly can be adjusted according to different specifications of fan rib blanks, ensuring the accuracy of the position of each fan rib blank along its length and guaranteeing that the dimensions of the cut fan ribs meet requirements, thus improving product precision.

[0031] The width clamping assembly employs two opposing material clamping fingers. Through the counter-movement of the first and second translational drive devices, precise clamping of the fan-shaped blank in the width direction is achieved. Furthermore, the translational actuator drives the stable movement of the material clamping fingers, ensuring the stability and uniformity of the clamping force. This prevents the fan-shaped blank from shifting due to insecure clamping during the cutting process, improving the flatness and dimensional accuracy of the cut edges.

[0032] The lifting assembly employs a design with two parallel lifting plates that move synchronously, ensuring stability when lifting fan rib blanks of varying widths. Simultaneously, the pushing assembly connects to an external linear drive device, allowing adjustment of the pushing speed and force to accommodate fan rib blanks of different thicknesses and materials.

[0045] See Figures 1-3 This utility model proposes a fan rib laser cutting device, comprising: a frame 100, on which a material conveyor belt 200 is fixedly mounted. The surface of the material conveyor belt 200 is evenly distributed with a plurality of material blocks 201, and each pair of adjacent material blocks 201 forms a fan rib receiving space. This ensures that the fan rib blank is stably placed on its surface during the operation of the material conveyor belt 200, and that it does not sway or shift due to the flexibility of the conveyor belt. The fan rib blank has a rectangular structure and is made of bamboo or wood.

[0046] The material conveyor belt 200 has a stacking bin 300 on the feeding side for neatly stacking the fan bone blanks to be cut on the feeding side of the material conveyor belt 200. The material conveyor belt 200 has a material distribution mechanism 400 on the discharging side. The material distribution 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 material distribution mechanism 400 and the material stacking mechanism 300. A laser cutting mechanism 600 and a fan bone picking robot 4012 are provided above the material positioning mechanism 500.

[0047] The material positioning mechanism 500 includes a lifting assembly 503 for lifting the fan blanks in a plurality of fan blank receiving spaces upward and detaching them from the material conveyor belt 200, a length positioning mechanism 800 for positioning one end of the fan blanks after being lifted by the lifting assembly 503 in the length direction, and a width clamping assembly 502 for clamping the fan blanks after being positioned by the length positioning mechanism 800 in the width direction.

[0048] The laser cutting mechanism 600 includes at least a plurality of laser cutting heads 6006 corresponding one-to-one with the fan rib blanks clamped by the width clamping assembly 502. The laser cutting mechanism 600 moves along the XYZ three axes to perform laser cutting on the fan rib blanks.

[0049] In this embodiment, the fan-shaped blanks are pushed out of the palletizing hopper 300 and precisely transported to the laser cutting area via the material conveyor belt 200, realizing an automated material feeding process, improving production efficiency, and reducing manual intervention and material loading and unloading time. Simultaneously, the material stops 201 on the material conveyor belt 200 form a fan-shaped blank receiving space to ensure stable transport of the blanks. Furthermore, the length positioning mechanism 800 and the width clamping assembly 502 have a certain degree of adjustability, accommodating fan-shaped blanks of different lengths and widths, enhancing the equipment's adaptability to different product specifications.

[0050] The material positioning mechanism, through the lifting assembly 503, length positioning mechanism 800, and width clamping assembly 502, quickly and accurately positions and clamps the fan rib blank in three dimensions, providing a stable working environment for laser cutting. This ensures the fan rib blank is firmly fixed in the designated position, reducing the impact of material shaking or vibration on cutting accuracy. Furthermore, the relative position between the laser cutting head 6006 and the fan rib blank remains constant, allowing the laser beam to precisely cut along a predetermined path, thus improving cutting quality.

[0051] In summary, the fan rib laser cutting equipment in this embodiment can be closely integrated with upstream and downstream processes. A stacking hopper 300 is provided on the feeding side, facilitating the stacking and storage of raw materials and also enabling connection with previous processes (such as the production of fan rib blanks). On the discharging side, the cut fan ribs can be classified and transported through the product conveying section 401 and waste conveying section 402 of the sorting mechanism 400, directly entering the next process (such as subsequent processing and assembly), achieving smooth connection of the entire production process and improving the overall efficiency and coordination of the production process.

[0052] 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. A width clamping component 502 and a lifting component 503 are fixed on the first mounting bracket 501, and the width clamping component 502 and the lifting component 503 are spaced apart.

[0053] The width clamping assembly 502 includes: a first lifting member 5021, which is fixedly connected to a first mounting bracket 501; a lifting platform 5022 is connected to the driving end of the first lifting member 5021; a first translation drive device 5028 and a second translation drive device 5029 are mounted on the lifting platform 5022; the first translation drive device 5028 and the second translation drive device 5029 have the same structure, but the driving direction of the first translation drive device 5028 is opposite to that of the second translation drive device 5029; the first translation drive device 5028 and the second translation drive device 5029 are mounted on... Each device is fixedly connected with a number of material clamping fingers 5027. Among these, a portion of the material clamping fingers 5027 is fixedly connected to the first translation drive device 5028, while the remaining portion is fixedly connected to the second translation drive device. 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 in pairs adjacent to each other. The pairs of adjacent material clamping fingers 5027 form a width clamping space, thereby moving towards or in opposite directions under the drive of the first translation drive device 5028 and the second translation drive device 5029 to clamp and fix fan rib blanks of different widths.

[0054] The first translation drive device 5028 includes: a translation driver 5023, a first clamping block 5024 and a second clamping block 5025 slidably provided on the drive end of the translation driver 5023, the first clamping block 5024 and the second clamping block 5025 are arranged opposite to each other, and a support drive plate 5026 is provided on the side of the second clamping block 5025 and the first clamping block 5024 that is away from each other, and the support drive plate 5026 is tightly connected to the material clamping finger 5027 to provide it with stable support and precise guidance.

[0055] The first lifting component 5021 can be driven by a cylinder, motor, hydraulic cylinder or other drive components to provide lifting force and realize the up and down movement function of the lifting platform 5022; the translation driver 5023 can be driven by a finger cylinder, electric cylinder or other drive components to adjust the relative position of the first clamping block 5024 and the second clamping block 5025 to ensure that the fan bone blank is accurately positioned in the width direction.

[0056] Furthermore, when it is necessary to clamp and fix fan-shaped blanks of different widths, the first lifting component 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.

[0057] As the lifting platform 5022 reaches the predetermined position, the first translation drive device 5028 and the second translation drive device 5029 begin to operate. Since the first translation drive device 5028 and the second translation drive device 5029 have the same structure but drive in opposite directions, they will respectively drive the first clamping block 5024 and the second clamping block 5025 connected to them to move towards each other or in opposite directions. During this process, the drive end of the translation actuator 5023 will slide along a specific track, thereby causing the first clamping block 5024 and the second clamping block 5025 to perform corresponding actions.

[0058] 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 on them also move accordingly. Since these material clamping fingers 5027 are arranged along the support drive plate 5026, they maintain accurate spacing and alignment during movement, thereby ensuring that fan-shaped blanks of different widths can be clamped evenly and firmly.

[0059] Once the fan rib blank is clamped, the laser cutting mechanism 600 starts to perform a precise cutting operation on the clamped fan rib blank. During the cutting process, because the material clamping finger 5027 provides a stable and reliable clamping force, the fan rib blank will not shift or shake, thus ensuring the accuracy and quality of the cutting.

[0060] After cutting, the first lifting component 5021 will drive the lifting platform 5022 to descend. 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 bone blank so that the cut fan bone blank can be taken out from the clamping assembly for subsequent processing or treatment.

[0061] In one embodiment, there are two material conveyor belts 200 that are parallel to each other, and a receiving space is formed between the two material conveyor belts 200, within which the width clamping assembly 502 is located.

[0062] In this embodiment, the width clamping assembly 502 is rationally arranged in the space between two parallel material conveyor belts 200, making the equipment structure more compact, thereby reducing the equipment's footprint and improving the space utilization rate of the production workshop. At the same time, it also allows material conveying, positioning, and cutting processes to be completed in a relatively centralized area, facilitating monitoring and management by operators.

[0063] See Figure 4 In order to improve the processing efficiency of laser cutting, in another embodiment, one end of the support drive plate 5026 extends toward the side of the frame 100 near the material distribution mechanism 400 to increase the number of fan-shaped blanks that the support drive plate 5026 can support at the same time, and a support mechanism 504 is provided below it to ensure that the support drive plate 5026 remains horizontal during the upward movement.

[0064] The support mechanism 504 includes: a second mounting bracket 5041, which is fixedly mounted on the side of the frame 100 near the material distribution mechanism 400. A third lifting member 5042 is fixedly mounted on the second mounting bracket 5041. The driving end of the third lifting member 5042 is connected to a support platform 5043, which enables the support platform 5043 to have axial lifting capability. The upper surface of the support platform 5043 is provided with a plurality of positioning grooves 5044 corresponding to the support drive plate 5026. 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.

[0065] Specifically, when the first lifting component 5021 drives the support drive plate 5026 to rise or fall, the support platform 5043 adjusts its height through the third lifting component 5042 to maintain the horizontal state of the support drive plate 5026.

[0066] Furthermore, in order to ensure the stability of the fan-shaped 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 component 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.

[0067] Both the third lifting component 5042 and the fourth lifting component can be driven by cylinders, motors, hydraulic cylinders, etc., to provide lifting force and realize the up-and-down movement of the support platform 5043 and the lifting plate 5033.

[0068] See Figure 5 In one embodiment, the initial plane of the lifting plate 5033 is higher than the initial plane of the support drive plate 5026. The upper end of the lifting plate 5033 is provided with an elastic pad, and a groove 5045 matching the shape of the fan rib blank is provided on the upper surface of the lifting plate 5033. A plurality of suction cups 5046 are evenly distributed inside the groove 5045.

[0069] Specifically, when the fan-shaped blank is supported above the material conveyor belt 200 by the lifting plate 5033 and the support drive plate 5026, the two adjacent material clamping fingers 5027 tightly adhere to the two sides of the bamboo board under the drive of the translation driver 5023. At this time, part of 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 drive plate 5026, in order to ensure that the lifting plate 5033 and the support drive plate 5026 are always in the same plane during the laser cutting process, so as to provide sufficient planar support for the bamboo board, the piston rod of the second lifting component 5031 will gradually retract, thereby driving the lifting plate 5033 to continuously adjust its position in the vertical direction, so that the suction cup 5046 on the elastic pad can tightly adhere to the surface of the bamboo board, further fixing the position of the bamboo board and preventing it from shifting during subsequent processing.

[0070] In one embodiment, the lifting assembly 503 includes two parallel lifting plates 5033, the lifting plates 5033 being connected to a second lifting member 5031 that drives the lifting plates 5033 to move up and down in the unlifted position and the lifted position, and the two lifting plates 5033 moving synchronously.

[0071] The second lifting component 5031 can also be driven by a cylinder, motor, hydraulic cylinder or other drive components to provide lifting force and realize the up and down movement function of the lifting plate 5033.

[0072] Specifically, the second lifting component 5031 is fixedly connected to the first mounting bracket 501 and is parallel to the first lifting component 5021. The driving end of the second lifting component 5031 is fixedly provided with a connecting shaft 5032, and a lifting plate 5033 is threadedly connected to the connecting shaft 5032.

[0073] In another embodiment, the second lifting member 5031 is fixedly connected to the first mounting bracket 501 and parallel to the first lifting member 5021. The driving end of the second lifting member 5031 is fixedly provided with a connecting shaft 5032, and a lifting rod is threaded onto the connecting shaft 5032.

[0074] This embodiment ensures that the two lifting plates 5033 maintain a strictly parallel state during movement. Simultaneously, the presence of the connecting shaft 5032 ensures the stability and synchronicity of the lifting plates 5033 during ascent and descent, reducing material swaying or uneven force distribution caused by tilting or asynchronous movement of the lifting plates. Furthermore, when the connecting shaft 5032 is driven by the drive end of the second lifting member 5031, the parallel arrangement of the two lifting plates 5033 allows them to rise or fall simultaneously and uniformly, ensuring smooth lifting of the fan-shaped blank.

[0075] See Figures 6-7In one embodiment, the length positioning mechanism 800 includes a backing plate 700 and a pushing assembly 8000 that moves linearly relative to the backing plate 700 on a horizontal plane, with a material conveyor belt 200 disposed between the backing plate 700 and the pushing assembly 8000. The backing plate 700 and the pushing assembly 8000 are distributed in the width direction of the material conveyor belt 200.

[0076] Specifically, the pusher assembly 8000 includes: a positioning pusher plate 8005, which is connected to a linear drive device 8006.

[0077] The linear drive device 8006 includes: a frame 8001, which is fixedly installed in the frame 100 on the side away from the backing plate 700. A transmission screw 8002 is provided 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. A drive mechanism is connected to the end of the transmission screw 8002 extending to the outside of the frame 8001 to drive the transmission screw 8002 to rotate. A screw nut 8003 is threadedly connected to the middle of the transmission screw 8002. A movable plate 8004 is fixed on the screw nut 8003. The movable plate 8004 is fixedly connected to the positioning push plate 8005.

[0078] The drive mechanism can be a motor, which is connected to the transmission screw 8002 via pulley transmission or direct drive to provide rotational power. When fine-tuning of the length of the fan-shaped blank is required, the motor is started, and the rotation of the transmission screw 8002 drives the screw nut 8003 to move along the material conveying direction, thereby enabling the positioning push plate 8005 fixed on the moving plate 8004 to accurately adjust the position of the bamboo board.

[0079] Furthermore, for those skilled in the art, the method of rotating the motor-driven lead screw 8002 is conventional technology. Therefore, it is not shown in the accompanying drawings.

[0080] In this embodiment, a backing plate 700 fixed to the side wall of the frame 100 serves as a reference surface for one side of the bamboo material board, further ensuring the accurate positioning of the bamboo material board in the width direction and preventing its lateral deviation. Then, the drive mechanism in the length positioning mechanism 800, i.e., a motor (not shown in the figure), is activated. The motor is connected to the transmission screw 8002 via pulley transmission or direct drive, providing rotational power to the transmission screw. Simultaneously, as the motor rotates, the transmission screw 8002 begins 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 its other end to move along the material conveying direction. The movement of the screw nut 8003 will then drive the movable plate 8004 fixed to it to move together. Since the positioning push plate 8005 is fixedly connected to the moving plate 8004, the positioning push plate will also move with the moving plate, thereby realizing the fine-tuning and positioning of the fan rib blank in the length direction, so as to ensure that the cutting accuracy of the bamboo board will not be affected by shaking or displacement during the laser cutting process.

[0081] Furthermore, a guide rod (not shown in the figure) is also provided inside the frame 8001. The guide rod is parallel to the transmission screw 8002, and its two ends are fixedly connected to the two side walls of the frame 8001 respectively. A through hole is provided on the screw nut 8003 for the guide rod to pass through, so that the screw nut 8003 can always slide smoothly along the direction of the guide rod when it moves along the screw axis, thereby improving the stability and accuracy of the positioning push plate 8005 movement and ensuring the accuracy and reliability of length positioning.

[0082] In one embodiment, a plurality of pre-positioning actuating elastic pieces 8007 are provided on the positioning surface of the positioning push plate 8005 at intervals, which cause the fan rib blank to move toward the back plate 700.

[0083] Among them, the pre-positioning actuating elastic plate 8007 adopts an arc (or arch) structure. One end of the pre-positioning actuating elastic plate 8007 is fixed on the inner side wall of the frame 8001, and the other end extends slightly towards the material conveyor belt 200, that is, it is in a free state.

[0084] Specifically, when the fan-shaped blank is conveyed on the material conveyor belt 200 to the position of the pre-positioning actuating elastic plate 8007, due to the arc-shaped structure design of the pre-positioning actuating elastic plate 8007, it can smoothly contact the side of the bamboo board. At the same time, at the instant the pre-positioning actuating elastic plate 8007 contacts the bamboo board, the pre-positioning actuating elastic plate 8007 will be squeezed by the bamboo board and undergo elastic deformation, thereby generating an elastic force pointing outward of the material conveyor belt 200, and the direction of this elastic force is perpendicular to the direction of movement of the bamboo board on the material conveyor belt 200.

[0085] The pre-positioning actuating elastic plate 8007 in this embodiment can effectively reduce the shaking of the bamboo board during the conveying process. Especially when the material conveyor belt 200 is fast or the bamboo board is heavy, the pre-positioning actuating elastic plate 8007 can play a guiding and stabilizing role, preventing the bamboo board from colliding with other components or deviating from the conveying path due to shaking. Furthermore, when the fan rib blank passes the pre-positioning actuating elastic plate 8007 during the conveying process, the pre-positioning actuating elastic plate 8007 can gently actuate the bamboo board to ensure that it moves steadily along the material conveying direction.

[0086] Furthermore, a sensor assembly is also installed on the frame 100 between the backing plate 700 and the length positioning mechanism 800. The sensor assembly includes a laser displacement sensor and a proximity switch. The laser displacement sensor is installed on the frame 8001, with its emitting end facing the upper surface of the fan-shaped 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 arrived at the processing area.

[0087] Specifically, when the fan rib blank is initially positioned and transported to the detection range of the proximity switch, the proximity switch sends a signal to trigger 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 height data of the bamboo board to the control system, and performs fine-tuning positioning operation through the control length positioning mechanism 800 to further ensure the accurate positioning of the fan rib blank in three-dimensional space.

[0088] Among them, the laser displacement sensor can be set to Omron ZX-LD60, which uses the reflection principle of laser beam to analyze the time difference or phase difference of reflected light to determine the distance of the object; the proximity switch can be set to Autonics PR12-11DN, which will cause the resistance value of the photosensitive element to change when the object blocks the light, thereby triggering the switch action.

[0089] Furthermore, for those skilled in the art, using sensor components to detect the position information of bamboo boards is a conventional technique. Therefore, it is not also shown in the accompanying drawings.

[0090] In another embodiment, a camera assembly (not shown) may also be installed on the frame 100. This camera assembly works in conjunction with the sensor assembly to capture real-time images of the position and status of the fan rib blank. Image processing and analysis techniques can further assist the control system in achieving precise positioning and cutting operations on the fan rib blank.

[0091] Specifically, the camera assembly can be mounted on the frame 8001 or the laser cutting mechanism 600, with its shooting direction facing the fan rib blank on the material conveyor belt 200. When the fan rib blank has been initially positioned and conveyed into the shooting range of the camera assembly, the camera assembly will capture the position and status images of the bamboo board in real time and transmit these image data to the control system. The control system, by processing and analyzing the image data, can accurately identify the position and orientation information of the fan rib blank 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.

[0092] See Figure 8 In one embodiment, the laser cutting mechanism 600 further includes: a laser generator 6001, which is fixed outside the frame 100. A cantilever 6002 is fixed on the side wall of the laser generator 6001 facing the material conveyor belt 200. A first moving part 6003 is fixed on the cantilever 6002, the axis of which is perpendicular to the material conveying direction. A second moving part 6004 is slidably mounted on the first moving part 6003. The second moving part 6004 is parallel to the material conveying direction. A plurality of third moving parts 6005 are slidably mounted on the second moving part 6004. A laser cutting head 6006 is connected to the third moving part 6005.

[0093] In this embodiment, by setting up the cantilever 6002, the laser cutting head 6006 can be stably positioned above the material conveyor belt 200 and can be moved quickly and accurately to the required cutting position, reducing the preparation work before cutting and the adjustment time during the cutting process, thereby improving the overall cutting efficiency.

[0094] The arrangement of the first moving part 6003 and the second moving part 6004 allows the third moving part 6005 and the laser cutting head 6006 to be precisely positioned perpendicular to the material conveying direction (Y-axis) and along the material conveying direction (X-axis). This enables the laser cutting head 6006 to accurately align with different parts of the fan-shaped blank to meet the cutting requirements of different sizes and shapes. Simultaneously, the third moving part 6005 provides the laser cutting head 6006 with axial lifting (Z-axis) capability, allowing for precise adjustment of the focal length between the laser cutting head 6006 and the fan-shaped blank according to different thicknesses and cutting requirements.

[0095] The first moving part 6003 and the second moving part 6004 can be equipped with driving components such as linear slide rail system, ball screw pair, pneumatic slide table, etc.; the third moving part 6005 can be equipped with driving components such as cylinder, motor, hydraulic cylinder, etc.

[0096] See Figure 9In one embodiment, the product conveying unit 401 includes: a mounting frame 4011, which is fixedly mounted above the cantilever 6002; a fan-shaped material handling robot 4012 is slidably mounted on the mounting frame 4011; and a product conveyor belt 4013 is fixedly mounted on the side of the mounting frame 4011 near the waste conveying unit 402.

[0097] The fan bone material handling robot 4012 includes: a sliding plate 4014, which is slidably mounted on the mounting frame 4011, enabling it to move along the material conveying direction, and a drive cylinder 4015 is fixedly mounted on the sliding plate 4014, with a fan bone suction cup 4016 mounted on the drive end of the drive cylinder 4015.

[0098] In this embodiment, the mounting frame 4011 is fixedly mounted above the cantilever 6002, providing a stable support structure for the fan rib material handling robot 4012. Simultaneously, the product conveyor belt 4013 ensures that after the fan rib suction cup 4016 grasps the bamboo slab, the conveyor belt can stably transport the bamboo slab to the cutting area, reducing the shaking or displacement of the bamboo slab caused by manual operation or unstable conveying.

[0099] On the other hand, the fan rib material handling robot 4012 adopts a sliding plate 4014 and mounting frame 4011 sliding cooperation design, which enables the fan rib suction cup 4016 to move quickly and accurately along the material conveying direction (i.e. the conveying direction of the fan rib blank). This ensures that the fan rib suction cup 4016 can quickly and accurately position and adsorb the bamboo board before it reaches the cutting position, improving the gripping efficiency and reducing scratches or damage to the surface of the bamboo board caused by collision or friction, thus ensuring the quality of the bamboo board after cutting.

[0100] See Figure 9 In one embodiment, the waste conveying unit 402 includes a waste collection box 4021, which is fixed below the product conveyor belt 4013.

[0101] In this embodiment, the waste collection box 4021 is directly fixed below 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. By utilizing gravity, the waste collection process is simplified and the efficiency of waste treatment is improved.

[0102] This application also provides a processing method for a fan rib laser cutting device, the fan rib laser cutting method comprising the following steps:

[0103] S1. Stack the fan-shaped blanks in the stacking silo 300;

[0104] S2. Start the material conveyor belt 200. The forward movement of the material conveyor belt 200 drives the evenly distributed material blocks 201 on it to push the fan bone blanks in the stacking bin 300 out of the stacking bin 300, so that there is one fan bone blank in each fan bone accommodating space.

[0105] S3. When the fan-shaped blanks in S2 enter the laser cutting area, the material conveyor belt 200 stops, and the lifting assembly 503 lifts several fan-shaped blanks upwards and removes them from the material conveyor belt 200; and

[0106] The length positioning mechanism 800 positions one end of the material lifted by the lifting assembly 503 along its length; and

[0107] The width clamping assembly 502 clamps the fan rib blank positioned by the length positioning mechanism 800 in its width direction.

[0108] S4, the laser cutting mechanism 600 performs laser cutting on the fan rib blank in S3 to obtain the fan rib.
