[0002] Natural rubber is known as one of the four major industrial raw materials along with steel, petroleum and coal. Due to its excellent wear resistance, impact resistance, elasticity and heat dissipation, especially in low temperature environments, the ductility and resilience of natural rubber are better than synthetic rubber. It is widely used in many fields such as military, aviation, medicine, industry and daily life.

[0003] In order to improve the collection efficiency of rubber, the prior art usually uses a rubber tapping machine to cut the bark of rubber trees so that latex can be collected later. In the research and development process of the rubber tapping machine, it is often necessary to test its rubber tapping accuracy and rubber tapping strength. However, due to the irregular growth of natural rubber trees, it is difficult to formulate a unified standard to measure the key indicators such as the positioning accuracy and rubber tapping strength of the rubber tapping machine, which causes the performance of the rubber tapping machine on different rubber trees to be difficult to verify.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0041] Combine the following Figures 1 to 6 The invention describes a rubber tree simulation experiment stand, a rubber tapping experiment system and a rubber tapping machine optimization method.

[0042] See also Figure 1 and Figure 2 As shown, the rubber tree simulation experiment stand 10 provided in the embodiment of the present invention includes: a flexible shell 110, a variable diameter driving device 120, a flexible display screen 130 and a matrix pressure sensor (not shown in the figure).

[0043] The first side and the second side of the flexible shell 110 are connected to form a column; the first side and the second side of the flexible shell 110 are both connected to the variable diameter driving device 120, and the variable diameter driving device 120 is used to drive the first side and the second side of the flexible shell 110 to move relative to each other to adjust the diameter of the flexible shell 110; the flexible display screen 130 is arranged on the shell, and the flexible display screen 130 is used to display the three-dimensional model of the rubber tree; the matrix pressure sensor is arranged on the flexible display screen 130 to sense the tapping pressure of the rubber tapping machine 20.

[0044] The rubber tree simulation experiment stand 10 provided by the present invention can display the three-dimensional model of the rubber tree by using the flexible display screen 130 fixed on the flexible shell 110, and drive the first side and the second side of the flexible shell 110 to move relative to each other through the variable diameter driving device 120, adjust the diameter of the flexible shell 110, simulate the rubber tree trunks of different breast diameters, realize the rubber tapping simulation experiment of the rubber tree trunks of different breast diameters, and improve the flexibility of the experimental stand. At the same time, the matrix pressure sensor can sense the rubber tapping pressure applied to the flexible display screen 130 by the rubber tapping machine 20, and can effectively carry out the rubber tapping simulation experiment.

[0045] Specifically, the flexible shell 110 is rectangular when unfolded, and its two lateral sides (the first side and the second side mentioned above) are connected to each other to form a cylindrical shape. Since the flexible shell 110 has elastic deformation ability, when the variable diameter driving device 120 drives the first side and the second side of the flexible shell 110 to move relative to each other (they can move closer to each other or away from each other), the diameter of the cylindrical simulated trunk structure formed by the flexible shell 110 can change, thereby changing the diameter.

[0046] The variable diameter driving device 120 is used to adjust the diameter of the flexible housing 110, and its working principle is as follows: the variable diameter driving device 120 includes a housing, a driving motor and a rotating shaft. The driving motor and the rotating shaft are both arranged in the housing, and the rotating shaft is rotatably connected to the housing. The upper and lower ends of the rotating shaft are provided with driving gears. The upper and lower ends of the flexible housing 110 are provided with a plurality of gear holes at intervals along the circumferential direction at the corresponding positions of the upper and lower ends, and the gear teeth of the driving gear are engaged with the corresponding gear holes. When adjusting, the driving motor drives the rotating shaft to rotate and drives the driving gear to rotate. The gear teeth of the driving gear drive the first side and the second side of the flexible housing 110 to move relative to each other in cooperation with the different gear holes, thereby realizing the diameter adjustment of the flexible housing 110.

[0047] The flexible display screen 130 is arranged on the outer wall of the flexible shell 110. When the diameter of the flexible shell 110 changes, the curvature of the flexible display screen 130 can adapt to the change of the flexible shell 110. The flexible display screen 130 can be used to display the three-dimensional model of the rubber tree, and because the flexible display screen 130 is provided with a matrix pressure sensor, when the floating tapping piece 210 of the tapping machine 20 moves on the flexible display screen 130 to simulate tapping, the flexible display screen 130 can display the current tapping track of the floating tapping piece 210 to determine whether the track deviates from the preset moving track, and collect the pressure applied by the floating tapping piece 210 to the flexible display screen 130 during tapping through the matrix pressure sensor to determine whether the tapping pressure applied by the floating tapping piece 210 exceeds the threshold.

[0048] See also Figure 2 As shown, according to some embodiments of the present invention, the rubber tree simulation experimental bench 10 also includes a support assembly 140, the support assembly 140 includes a push rod 141 and a support unit 142, the support unit 142 includes a support disk 1421 and a plurality of support arms 1422, the support disk 1421 is arranged on the push rod 141, and the plurality of support arms 1422 are arranged on the support disk 1421 at intervals along the circumferential direction, the first end of the support arm 1422 is hinged to the support disk 1421, and the second end of the support arm 1422 is hinged to the inner wall of the flexible shell 110.

[0049] By providing the support assembly 140, the flexible shell 110 can be supported from the inside, and the flexible shell 110 at the current diameter can be stabilized, thereby improving its stability during the experiment. The support assembly 140 can support and stabilize the flexible shell 110 when it is at different diameters.

[0050] Specifically, when the driving push rod 141 moves vertically, the first end of each support arm 1422 located on the support plate 1421 can move vertically. During the vertical movement of the first end of the support arm 1422, the inclination angle of the support arm 1422 changes (the length in the horizontal direction changes), so that the flexible shell 110 can be supported and stabilized when it is at different diameters.

[0051] It should be noted that the number of the support unit 142 on the push rod 141 is at least one, which may be single or multiple. The number of the support arms 1422 on the support plate 1421 is at least two, and three are used as an example in this embodiment.

[0052] Preferably, according to some embodiments of the present invention, the support assembly 140 includes a plurality of support units 142 , and the plurality of support units 142 are vertically spaced apart.

[0053] By vertically arranging a plurality of support units 142 at intervals on the push rod 141, different vertical positions of the flexible housing 110 can be supported and stabilized, further improving its stability. As an example, three support units 142 are vertically arranged at intervals on the push rod 141 in this embodiment to support and stabilize the upper, middle and lower parts of the flexible housing 110, respectively.

[0054] See also Figure 2 As shown, according to some embodiments of the present invention, the support assembly 140 further includes a plurality of connecting arms 143 , which are circumferentially spaced apart on the inner wall of the flexible shell 110 , and the second end of the support arm 1422 is hinged to the corresponding connecting arm 143 .

[0055] By setting up multiple connecting arms 143, firstly, a hinge seat can be set at the corresponding position on the connecting arm 143 to facilitate configuring the second end of the support arm 1422 and the corresponding connecting arm 143 to be hinged. Secondly, the connecting arm 143 can strengthen the structural strength of the flexible shell 110 and improve its deformation resistance.

[0056] As an example, the support assembly 140 in this embodiment includes three connecting arms 143 (corresponding one to one with the support arms 1422 on each of the above-mentioned support plates 1421), and the three connecting arms 143 are evenly arranged along the circumferential direction on the inner wall of the flexible shell 110, and are used to connect the corresponding connecting arms 143 of different support units 142 respectively.

[0057] See also Figure 1 and Figure 2 As shown, according to some embodiments of the present invention, the rubber tree simulation experimental bench 10 further includes a base 150 , and the flexible shell 110 is disposed on the base 150 .

[0058] By providing the base 150 , the flexible housing 110 and the driving components corresponding to the push rod 141 can be fixed, thereby improving the integrity of the device and making the device easier to transfer.

[0059] The rubber tapping experimental system provided by the present invention is described below. The rubber tapping experimental system described below and the rubber tree simulation experimental stand 10 described above can correspond to each other.

[0060] See also Figure 1 and Figure 3 and Figure 4As shown, the rubber tapping experiment system provided by the embodiment of the present invention includes a rubber tapping machine 20, a posture sensor 30, a control unit 40 and a rubber tree simulation experiment stand 10 as described in any of the above embodiments, the rubber tapping machine 20 includes a floating rubber tapping piece 210, the floating rubber tapping piece 210 can move along a set path on the flexible display screen 130 and apply pressure to the matrix pressure sensor, the posture sensor 30 is arranged on the rubber tapping machine 20, the posture sensor 30 is used to collect the position information and posture information of the floating rubber tapping piece 210, the rubber tapping machine 20, the posture sensor 30 and the flexible display screen 130 are all communicatively connected with the control unit 40.

[0061] The rubber tapping experimental system provided by the present invention can realize high-precision rubber tapping simulation, real-time posture adjustment, intelligent control and real-time data feedback by integrating a rubber tapping machine 20, a posture sensor 30, a control unit 40 and a rubber tree simulation experimental stand 10. It can not only accurately simulate the rubber tapping process, but also has strong adaptability and flexibility, providing an efficient and reliable experimental platform, which helps researchers optimize rubber tapping technology, increase rubber production, and promote technological progress in the rubber industry.

[0062] Specifically, the rubber tapping machine 20 includes a floating rubber tapping member 210, which can move along a set path relative to the flexible display screen 130 and apply pressure to the flexible display screen 130, thereby realizing simulated rubber tapping.

[0063] The attitude sensor 30 has a built-in three-axis gyroscope and a three-axis acceleration sensor. The three-axis gyroscope is used to detect the angle of the floating tapping piece 210 relative to the center line of the flexible display screen 130 in real time; the three-axis acceleration sensor is used to detect the three-dimensional distance of the floating tapping piece 210 relative to the center point of the flexible display screen 130 in real time.

[0064] The control unit 40 is used to control the operation of the system, receive and process sensor data, and adjust the angle and scale of the model on the flexible display screen 130. The control unit 40 can be a computer, a tablet computer, a smart phone, or a single-chip microcomputer with input and output functions.

[0065] In order to avoid damage to the flexible display screen 130 during the experiment, the tool portion of the floating rubber cutting member 210 can use a flexible cutting knife (such as a rubber cutting knife) to simulate a metal cutting knife.

[0066] See also Figure 3 and Figure 5 As shown, according to some embodiments of the present invention, the posture sensor 30 is disposed on the floating rubber tapping piece 210 , and a calibration hole 310 is provided on the posture sensor 30 . The calibration hole 310 is used to align with the marking point on the flexible display screen 130 to calibrate the position of the floating rubber tapping piece 210 .

[0067] By arranging the posture sensor 30 on the floating tapping piece 210, the posture sensor 30 can move synchronously with the floating tapping piece 210 when the floating tapping piece 210 moves, ensuring that the posture sensor 30 can continuously detect the relative position changes of the tapping piece without the need for an independent positioning system or complex external equipment, thereby simplifying the structure and reducing external error sources, thereby improving the detection accuracy of the posture sensor 30.

[0068] In addition, the posture sensor 30 is provided with a calibration hole 310, which can be used to calibrate the marking points on the flexible display screen 130, and can further improve the detection accuracy of the posture sensor 30. Figure 4 As shown, at the beginning of the experiment, the rubber tree simulation test bench 10 is set to the calibration mode, and the alignment disk ( Figure 4 As shown on the right side of the figure, adjust the position of the floating tapping member 210 until the center point of the alignment disk is just seen through the calibration hole 310 on the attitude sensor 30.

[0069] See also Figure 3 As shown, according to some embodiments of the present invention, the tapping machine 20 further includes a guide member 220 , and the floating tapping member 210 is disposed on the guide member 220 , and the floating tapping member 210 can move along the extension direction of the guide member 220 .

[0070] By providing the guide member 220, the floating rubber tapping member 210 can be guided, a fixed movement path can be provided, and the rubber tapping member can be ensured to move smoothly along a predetermined direction during operation. At the same time, during the experiment, it can also be verified whether the moving trajectory of the floating rubber tapping member 210 is offset under the guiding action of the guide member 220, and whether the pressure applied by the floating rubber tapping member 210 to the flexible display screen 130 under the guiding action of the guide member 220 is within the threshold range.

[0071] The following is a description of the tapping machine optimization method provided by the present invention. The tapping machine optimization method described below and the rubber tree simulation experiment stand 10 and the tapping experiment system described above can be referenced to each other.

[0072] See also Figure 6 As shown, the rubber tapping machine optimization method provided by the embodiment of the present invention is implemented based on the rubber tapping experimental system described in any of the above embodiments, and includes the following steps.

[0073] S610 , selecting rubber tree experimental parameters in the control unit 40 , the rubber tree experimental parameters including the diameter at breast height, epidermal texture and three-dimensional model of the rubber tree, and aligning the three-dimensional model with the rubber tree model on the flexible display screen 130 .

[0076] S640: Based on the position information and posture information of the floating tapping unit 210, adjust the angle and scale of the rubber tree model to simulate the motion trajectory of the floating tapping unit 210 on the rubber tree model.

[0077] S650, comparing the position information and posture information of the floating tapping unit 210 with the preset position information and the pre-examination posture information, and determining the horizontal offset, vertical offset and centerline inclination angle of the floating tapping unit 210.

[0078] S660: Optimize the design parameters of the rubber tapping machine 20 based on the horizontal offset, vertical offset and centerline inclination angle of the floating tapping member 210.

[0079] The rubber tapping machine optimization method provided by the present invention uses a rubber tapping experimental system to conduct experiments, which can accurately determine the position information and posture information of the rubber tapping machine 20 when conducting simulation tests on rubber trees with different breast diameters, and can further determine the horizontal offset, vertical offset and centerline inclination angle of the floating tapping part 210. Researchers can optimize the design parameters of the rubber tapping machine 20 based on the above data, thereby improving the tapping efficiency and quality of the rubber tapping machine 20.

[0080] According to some embodiments of the present invention, the rubber tapping machine optimization method further includes the following steps.

[0081] The pressure data of the floating tapping unit 210 during the simulation of tapping is obtained.

[0082] Based on the pressure data of the floating tapping member 210 during the simulated tapping, the design parameters of the tapping machine 20 are optimized.

[0083] By obtaining the pressure data of the floating tapping piece 210 during simulated tapping, combined with data analysis and design parameter optimization, the accuracy and stability of the tapping machine 20 during tapping can be effectively improved.

[0084] The following is a specific example of the rubber tapping machine optimization method provided by the present invention.

[0085] Before the experiment begins, the rubber tapping experiment system needs to be built. During the construction of the rubber tapping experiment system, the flexible display screen 130 and the matrix pressure sensor are tightly bonded and fixed to the flexible housing 110 by bolts. The attitude sensor 30 is installed on the floating rubber tapping part 210 of the rubber tapping machine 20, and it is ensured that the attitude sensor 30 can move synchronously with the floating rubber tapping part 210. The tool part of the floating rubber tapping part 210 can use a flexible cutting knife (such as a rubber cutting knife) to simulate a metal cutting knife.

[0086] After the rubber tapping experiment system is built, pre-experimental pre-processing work is required. First, the user can select the parameters of the rubber tree in the control unit 40, including the diameter at breast height, epidermal texture and three-dimensional model. Among them, the epidermal texture map and three-dimensional model of the rubber tree can be made using special tools such as 3D Max, Maya, Unity3D, and the control unit 40 can use tools such as three.js or Unity3D to display the virtual model of the rubber tree. In addition, if the rubber tapping machine 20 uses a semi-circular rubber tapping track mechanism (the above-mentioned guide member 220) pre-fixed on the rubber tree, it is also necessary to separately model the semi-circular rubber tapping track mechanism and fix it with the rubber tree model. Then, the three-dimensional model in the control unit 40 is aligned with the rubber tree model on the flexible display screen 130. Since the actual rubber tapping height may exceed the overall height of the experimental bench, the rubber tapping height and lifting speed can be input into the control unit 40, and the control unit 40 displays the corresponding height three-dimensional image of the rubber tree model on the flexible display screen 130 according to the height and speed.

[0087] After the above-mentioned pretreatment work is completed, it is necessary to calibrate the position of the floating rubber tapping part 210. During calibration, the rubber tree simulation experiment stand 10 is set to the calibration mode, and the alignment disk is displayed on the flexible display screen 130, and the position of the floating rubber tapping part 210 in the rubber tapping machine 20 is adjusted until the alignment disk center point is just seen through the calibration hole 310 on the attitude sensor 30. The distance between the calibration hole 310 of the attitude sensor 30 and the two ends of the fixed hole or the tool of the rubber tapping machine 20 is set on the rubber tree simulation experiment stand 10.

[0088] After calibration, the rubber tapping simulation experiment can be started. During the experiment, the main axis of the rubber tapping machine 20 is always parallel to the center line of the flexible display screen 130, and the attitude sensor 30 can collect the position information and attitude information of the floating rubber tapping piece 210 in real time. The control unit 40 receives the position information and attitude information of the floating rubber tapping piece 210 collected by the attitude sensor 30, and adjusts the model angle and scale on the flexible display screen 130 according to the position information and attitude information of the floating rubber tapping piece 210 to simulate the motion trajectory of the floating rubber tapping piece 210 on the rubber tree model. The matrix pressure sensor can obtain the pressure data of the floating rubber tapping piece 210 when simulating rubber tapping, and transmit the pressure data to the control unit 40, and the control unit 40 adjusts the rubber tapping trajectory of the floating rubber tapping piece 210 according to the pressure data to avoid excessive damage to the rubber tree.

[0089] After the rubber tapping simulation experiment is completed, the control unit 40 can compare the position information and posture information of the floating tapping unit 210 with the preset position information and the pre-examination posture information respectively, and determine the horizontal offset, vertical offset and centerline inclination angle of the floating tapping unit 210, and optimize the visual recognition algorithm, knife position, tapping force and disengagement position of the rubber tapping machine 20 according to the above-mentioned horizontal offset, vertical offset and centerline inclination angle, so as to improve the tapping efficiency and quality of the rubber tapping machine 20.
