Description

Technical Field

[0001] The utility model relates to the technical field of bamboo product production and processing, in particular to a device that can facilitate the rotary cutting processing of bamboo tubes. Background Art

[0002] Bamboo is widely used in the fields of architecture, furniture, tableware, etc. As a renewable natural material, it has many advantages such as environmental protection, durability, and easy processing. Therefore, with the improvement of people's living standards and the enhancement of environmental awareness, the market demand for bamboo products has been increasing in recent years, and the production of bamboo products has gradually become an important industrial pillar in some regions.

[0003] In the production process of bamboo products, the bamboo tube rotary cutting equipment is a very important device. Currently, a common one is a bamboo tube rotary cutting device disclosed in CN217669942U. This type of bamboo tube rotary cutting device uses a lead screw to control two chuck assemblies to move away from or close to each other, so as to clamp bamboo tubes of different lengths from both ends, and then uses a tool to perform rotary cutting processing on the bamboo tubes.

[0004] However, this type of bamboo tube rotary cutting device still has the following defects in the use process: First, before clamping the bamboo tube with the chuck assembly, it is necessary to align the axis of the bamboo tube. This step is usually commonly known as "centering". Currently, this centering step is usually completed by the operator's visual inspection and manual adjustment, which not only has low efficiency but also has a large error, and is very likely to cause the bamboo tube to be eccentric during rotation, affecting the rotary cutting quality. Second, the diameters and wall thicknesses of different parts of the same bamboo tube are not the same. Therefore, the traditional bamboo tube rotary cutting device needs to cut more materials to process a bamboo tube with a uniform wall thickness, and the material yield is low. Therefore, it is necessary to further improve the existing bamboo tube rotary cutting device. Summary of the Utility Model

[0005] The first technical problem to be solved by the utility model is to provide a bamboo tube rotary cutting device that can improve the centering efficiency and accuracy in view of the above-mentioned prior art status.

[0006] The second technical problem to be solved by the utility model is to provide a bamboo tube rotary cutting device that can improve the material yield of bamboo in view of the above-mentioned prior art status.

[0007] The technical solution adopted by the utility model to solve the first technical problem is: A bamboo tube rotary cutting device, comprising:

[0008] A frame;

[0009] A clamping mechanism, arranged on the frame, for clamping the bamboo tube to be processed. The clamping mechanism includes two clamping members that can approach and move away from each other to clamp or loosen the bamboo tube to be processed;

[0010] A first driving source, connected to the clamping member, for driving the clamping member to rotate;

[0011] A cutting mechanism, located at the rear side of the clamping mechanism, for cutting a bamboo tube to be processed;

[0012] It is characterized in that:

[0013] A placement rack for placing the bamboo tube to be processed is also provided adjacent to the clamping mechanism. The bamboo tube rotary cutting device further includes a visual detection mechanism. The visual detection mechanism includes visual probes arranged on both sides of the placement rack to identify the axis of the bamboo tube to be processed. Correspondingly, the visual detection mechanism is also connected to the feeding mechanism in a controlled manner. Thus, when the bamboo tube to be processed is transferred from the placement rack to the clamping mechanism by the feeding mechanism, the axis of the bamboo tube to be processed is aligned with the axis of the clamping mechanism.

[0014] To solve the second technical problem, preferably, the visual detection mechanism further includes a processor signal-connected to the visual probes. The visual probes can obtain the perimeter and wall thickness data of both ends of the bamboo tube to be processed for the processor to analyze and obtain corresponding cutting data. The processor is also connected to the clamping mechanism and / or the cutting mechanism in a controlled manner to control the rotary cutting thickness of the bamboo tube to be processed. By the cooperation of the processor and the visual probes, the perimeter and wall thickness of both ends of the bamboo tube to be processed can be detected, and the external shape trend and required cutting allowance of the bamboo tube to be processed can be automatically calculated. Thus, the feeding amount is adaptively adjusted by controlling the clamping mechanism and / or the cutting mechanism according to the external contour structure of the bamboo tube to be processed for rotary cutting, which can effectively improve the yield rate of the bamboo tube to be processed.

[0015] To enable the processor to control the cutting feed amount of the cutting mechanism, preferably, the cutting mechanism includes a tool and a second driving source for controlling the tool to move towards or away from the bamboo tube to be processed, and the second driving source is connected to the processor in a controlled manner. The second driving source can be selected according to accuracy requirements, such as a servo motor, a stepping motor, and a linear motor, etc. Under the control connection of the processor, the cutting feed amount of the cutting mechanism can be controlled by the second driving source, and the adaptive adjustment according to the external contour structure of the bamboo tube to be processed can be realized.

[0016] To improve the rotary cutting accuracy of the bamboo tube rotary cutting device, preferably, the first driving source and the second driving source are servo motors. By setting both the first driving source and the second driving source as servo motors, it is convenient to synchronously and accurately control the rotary cutting size, enabling the first driving source and the second driving source to cooperate with each other and greatly improving the rotary cutting accuracy.

[0017] In order to transmit the power of the second drive source to the tool to control the cutting feed rate, preferably, the tool is connected to the power output shaft of the second drive source through a connecting member. The power output shaft is a lead screw structure, and the connecting member is provided with a mating portion through which the power output shaft passes and is in transmission cooperation, so as to convert the rotational power of the power output shaft into linear power along the length direction of the power output shaft. By means of the lead screw transmission structure in cooperation with the second drive source, the rotational power of the power output shaft can be converted into linear power with high precision and transmitted to the tool, enabling the tool to move forward and backward towards the clamping mechanism to adjust the cutting feed rate.

[0018] Furthermore, in order to improve the stability of the cutting mechanism, preferably, the second drive source is provided with two mutually parallel power output shafts. Correspondingly, the connecting member has two mating portions corresponding to the power output shafts. Compared with only having one power output shaft, adopting two lead screw structures can significantly increase the stability of the tool during the rotary cutting process, thereby reducing the errors generated by the cutting mechanism due to factors such as force and vibration.

[0019] In order to enable the loading mechanism to transfer the bamboo tube to be processed to the clamping mechanism, preferably, the loading mechanism includes a loading robotic arm for transferring the bamboo tube to be processed, and a clamping jaw is provided at the clamping end of the loading robotic arm. Using the loading robotic arm to transfer the bamboo tube to be processed takes into account its high precision and flexibility. After the visual detection mechanism obtains the axis position data of the bamboo tube to be processed through the visual probe, the loading robotic arm can quickly and accurately transfer the bamboo tube to be processed, aligning the axis of the bamboo tube to be processed with the axis of the clamping mechanism to complete the centering work. This solution has higher efficiency and precision compared to manual centering by operators.

[0020] In order to avoid interference between the placement rack and the clamping jaw, preferably, the placement rack is composed of two pedestal columns arranged on the machine frame. The upper end of the pedestal column has a placement portion, and the placement portion is provided with an arc-shaped placement surface for cooperating with the bamboo tube to be processed. A preset distance is maintained between the two pedestal columns to avoid interference with the clamping jaw. Such a design is to enable the clamping jaw to be placed between the two pedestal columns with a preset distance, thus reserving space to avoid interference between the clamping jaw and the placement rack during the transfer process.

[0021] In order to enable the visual probe to detect both ends of the bamboo tube to be processed, preferably, an installation bracket for installing the visual probe is further provided on the outer side of the pedestal column, and the visual probe is installed at the upper end of the installation bracket to align with the placement portion. Through the installation bracket, the visual probe can be fixed to both sides of the placement rack with a very simple structure, thereby detecting the data of both ends of the bamboo tube to be processed located on the placement rack.

[0022] To facilitate the transfer of the bamboo tube to be processed by the loading robotic arm, preferably, the clamping mechanism is located between the cutting mechanism and the placement rack, and the loading robotic arm is arranged on the front side of the placement rack. With this layout, the loading robotic arm can maintain a relatively short distance from the placement rack and the clamping mechanism for easy transfer work, and at the same time, it can avoid interference with the cutting mechanism.

[0023] Compared with the prior art, the advantages of the present utility model are as follows:

[0024] 1. The bamboo tube rotary cutting device includes a vision detection mechanism, and can identify the axis of the bamboo tube through the vision probes arranged on both sides of the placement rack by the vision detection mechanism. Subsequently, the vision detection mechanism can control the loading mechanism to align the axis of the bamboo tube with the axis of the clamping mechanism to complete the centering work, which can greatly improve the centering efficiency and accuracy, so as to improve the processing quality and yield of the bamboo tube;

[0025] 2. The vision detection mechanism also has a processor. By cooperating with the vision probes through the processor, it can detect the perimeter and wall thickness data of both ends of the bamboo tube, and can automatically calculate the external shape trend and the required cutting allowance of the bamboo tube, so as to control the clamping mechanism and / or the cutting mechanism to adaptively adjust the feed rate for rotary cutting along with the external contour structure of the bamboo tube, which can effectively improve the yield of the bamboo tube.

[0034] The following further describes the present utility model in detail with reference to specific embodiments.

[0035] As Figures 1 to 5 shown, it is a preferred embodiment of the present utility model. The bamboo tube rotary cutting device includes a frame 1, and a clamping mechanism 2 for clamping the bamboo tube B to be processed is arranged on the frame 1. The clamping mechanism 2 includes two clamping members 21 that can approach and separate from each other to clamp or release the bamboo tube B to be processed. It also includes a first driving source 22 connected to the clamping member 21 to drive the clamping member 21 to rotate. A cutting mechanism 3 for cutting the bamboo tube B to be processed is arranged at the rear side of the clamping mechanism 2. In this embodiment, the clamping member 21 is in a disc shape, and there are a plurality of convex portions on the clamping surface to increase the clamping force. This structure is safer compared to self-centering components such as three-jaw chucks and is not easy to pinch or even crack the bamboo tube B to be processed. One of the clamping members 21 is connected to the first driving source 22, and the other clamping member 21 can move to clamp or release the bamboo tube B to be processed. Refer to Figures 1 to 2 , a placement rack 4 for placing the bamboo tube B to be processed is arranged adjacent to the clamping mechanism 2. The bamboo tube rotary cutting device further includes a visual detection mechanism 5, and the visual detection mechanism 5 includes visual probes 51 arranged on both sides of the placement rack 4 to identify the axis of the bamboo tube B to be processed. Correspondingly, the visual detection mechanism 5 is also connected to the feeding mechanism 6 for control. Then, when the bamboo tube B to be processed is moved from the placement rack 4 to the clamping mechanism 2 by the feeding mechanism 6, the axis of the bamboo tube B to be processed is aligned with the axis of the clamping mechanism 2. Compared with the traditional manual centering method, the centering work by the visual detection mechanism 5 and the feeding mechanism 6 can greatly improve the centering efficiency and accuracy, and improve the processing quality and yield of the bamboo tube.

[0036] Regarding the function of the visual probe 51, it can not only be used for centering the bamboo tube B to be processed, but also for obtaining data such as the circumference and wall thickness of the bamboo tube B to be processed. Specifically, the visual detection mechanism 5 further includes a processor 52 signal-connected to the visual probe 51. The visual probe 51 is used to obtain the circumference and wall thickness data at both ends of the bamboo tube B to be processed for the processor 52 to analyze and obtain the corresponding cutting data. The processor 52 is also connected to the cutting mechanism 3 for control to control the rotary cutting thickness of the bamboo tube B to be processed. By cooperating the processor 52 with the visual probe 51, the circumference and wall thickness at both ends of the bamboo tube B to be processed can be detected, and the external shape trend and required cutting allowance of the bamboo tube B to be processed can be automatically calculated. Thus, the cutting mechanism 3 is controlled to adaptively adjust the feed amount according to the external contour structure of the bamboo tube B to be processed for rotary cutting, which can effectively improve the yield of the bamboo tube B to be processed. In addition, according to actual needs, the feed amount of rotary cutting can also be adjusted by setting a multi-dimensional displacement table on the clamping mechanism 2.

[0037] In terms of the structure of the cutting mechanism 3, as Figures 3 to 5 shown, the cutting mechanism 3 includes a cutter 31 and a second driving source 32 for controlling the movement of the cutter 31 towards or away from the bamboo tube B to be processed, and the second driving source 32 is connected to the processor 52 for control. In order to improve the cutting accuracy of the bamboo tube cutting device, the first driving source 22 and the second driving source 32 are selected as servo motors. Setting both the first driving source 22 and the second driving source 32 as servo motors can facilitate the synchronous and precise control of the cutting size, enabling the first driving source 22 and the second driving source 32 to cooperate with each other and greatly improving the cutting accuracy. In this embodiment, the cutter 31 is connected to the power output shaft 321 of the second driving source 32 through a connecting member 33. The power output shaft 321 is of a lead screw structure. The connecting member 33 is provided with a mating portion 331 through which the power output shaft 321 passes and is in transmission cooperation, so as to convert the rotational power of the power output shaft 321 into linear power along the length direction of the power output shaft 321, enabling the connecting member 33 to carry the cutter 31 to move axially forward and backward. In this embodiment, the connecting member is a plate-shaped member with an L-shaped cross-section. Its vertical upper end is connected with the cutter 31 and guide rails are also connected to both ends along the length direction of the cutter 31. The lower side of the horizontal end is provided with the mating portion 331 and guide rails are also connected to both ends. The mating portion 331 is a through hole for the power output shaft 321 to pass through, and is provided with a thread structure adapted to the lead screw of the power output shaft 321. Through the lead screw transmission structure in cooperation with the second driving source 32, the rotational power of the power output shaft 321 can be converted into linear power with high precision and transmitted to the cutter 31. Further, in order to improve the stability of the cutting mechanism 3, the second driving source 32 is provided with two mutually parallel power output shafts 321. Correspondingly, the connecting member 33 has two mating portions 331 corresponding to the power output shafts 321. Compared with only setting one power output shaft 321, using two lead screw structures can greatly increase the stability of the cutter 31 during the cutting process, thereby reducing the errors of the cutting mechanism 3 caused by factors such as force and vibration.

[0038] Finally, in order for the feeding mechanism 6 to transfer the bamboo tube B to be processed to the clamping mechanism 2, the feeding mechanism 6 includes a feeding robotic arm 61 for transferring the bamboo tube B to be processed, and a clamping end 62 of the feeding robotic arm 61 is provided with a clamping jaw 63. Using the feeding robotic arm 61 to transfer the bamboo tube B to be processed takes into account its high precision and flexibility. After the vision detection mechanism 5 obtains the axis position data of the bamboo tube B to be processed through the vision probe 51, the feeding robotic arm 61 can quickly and accurately transfer the bamboo tube B to be processed, aligning the axis of the bamboo tube B to be processed with the axis of the clamping mechanism 2 to complete the centering work. This solution has higher efficiency and precision compared to manual centering by operators. Since the bamboo tube B to be processed is transferred by the clamping jaw 63, the placement rack 4 is composed of two columnar supports 41 arranged on the frame 1. The upper end of the columnar support 41 has a placement portion 42, and the placement portion 42 is provided with an arc-shaped placement surface for cooperating with the bamboo tube B to be processed. A preset distance H is maintained between the two columnar supports 41. If the placement rack 4 does not reserve a certain space, interference may occur with the clamping jaw 63 during the transfer process. Therefore, a preset distance H is maintained between the two columnar supports 41 to avoid interference with the clamping jaw 63. An installation bracket 43 for installing the vision probe 51 is also provided on the outer side of the columnar support 41, and the vision probe 51 is installed at the upper end of the installation bracket 43 to align with the placement portion 42. Through the installation bracket 43, the vision probe 51 can be fixed to both sides of the placement rack 4 with a very simple structure, so as to detect both ends of the bamboo tube B to be processed placed on the placement rack 4. In addition, in this embodiment, the clamping mechanism 2 is located between the cutting mechanism 3 and the placement rack 4, and the feeding robotic arm 61 is arranged on the front side of the placement rack 4. Through this layout, the feeding robotic arm 61 can maintain a relatively short distance from the placement rack 4 and the clamping mechanism 2 for easy transfer work, and at the same time, it can avoid interference with the cutting mechanism 3.

[0039] The specific working process of the bamboo tube rotary cutting device in this embodiment is as follows:

[0040] As Figure 6 shown, at this time, the clamping jaw 63 of the feeding robotic arm 61 grabs the bamboo tube B to be processed and places it on the placement rack 4. The vision probes 51 on both sides of the placement rack 4 obtain the axis position data of the bamboo tube B to be processed, and at the same time, obtain the perimeter and wall thickness data of both ends of the bamboo tube B to be processed. The processor 52 then calculates the cutting data of the bamboo tube B to be processed; after the above work is completed, as Figure 7 shown, the clamping jaw 63 of the feeding robotic arm 61 transfers the bamboo tube B to be processed to the clamping mechanism 2, and at the same time aligns the axis of the bamboo tube B to be processed with the axis of the clamping mechanism 2. The two clamping members 21 approach each other to clamp the bamboo tube B to be processed to complete the centering and clamping work; finally, refer to Figure 8, the jaws 63 of the loading robot arm 61 release the bamboo tube B to be processed on the clamping mechanism 2, and start to grasp another bamboo tube B to be processed for centering work. At the same time, the first driving source 22 drives the clamping member 21 to rotate, and the second driving source 32 controls the cutting tool 31 to adaptively adjust the cutting feed amount according to the corresponding circumference and wall thickness characteristics and follow the edge shape of the bamboo tube B to be processed by following the data obtained by the vision detection mechanism 5 to complete the rotary cutting work.
