[0002] Materials refer to all kinds of raw materials required in the production, manufacturing, or service process. In the production of materials in the food category, cutting fruits in half and removing the pits is a common step, such as in betel nuts, dried apples, and dried apricots.

[0003] After the whole fruit is cut into two halves by a blade, the pit inside the fruit half is exposed, facilitating the subsequent pitting operation. In related technologies, a conveyor line is used to transport the fruit halves. When the fruit half on the conveyor line moves to the pitting station, a robotic arm removes the pit from the inside of the fruit half located at the pitting station.

[0004] In actual use, the fruit pits at the robotic arm's picking end may fall off during the above-mentioned pit removal method. The fallen pits may get stuck in the conveyor belt rollers or other transmission components, causing equipment downtime or mechanical failure, and affecting overall production efficiency. Summary of the Invention

[0005] To address the issue of fruit pits falling off the robotic arm during actual use of the aforementioned pitting method, which could become stuck in conveyor belt rollers or other transmission components, causing equipment downtime or mechanical failure and affecting overall production efficiency, this application provides a material pitting system with the following technical solution: It includes a first mounting frame and a second mounting frame. A turntable is rotatably connected to the first mounting frame, and a receiving mechanism is provided on the turntable. The first mounting frame also has a drive mechanism for rotating the turntable. The second mounting frame has a pitting mechanism, which is vertically offset from the receiving mechanism. The pitting mechanism removes the pit from the lower half of the fruit below the receiving mechanism.

[0006] In one specific implementation scheme, the receiving mechanism includes a positioning device and an opening device. The opening device has a receiving space. The positioning device pushes and positions the fruit half in the receiving space, and the opening device opens the inner cavity of the positioned fruit half.

[0007] In one specific implementation, the positioning device includes a push rod disposed on a turntable, and the turntable is provided with a first driving part that drives the push rod to move. The first driving part is activated to push and position the half of the fruit against the receiving space through the push rod.

[0008] In one specific implementation, the cavity-opening device includes an embedding unit, and the turntable is provided with a driving unit that drives the embedding unit to move. The embedding unit embeds into the fruit half and opens the inner cavity of the fruit half under the drive of the driving unit.

[0009] In one specific implementation, the embedding unit includes at least two embedding components disposed opposite to each other on the turntable. Each embedding component includes a connecting frame disposed on the drive unit. The connecting frame is provided with two protrusions, which are respectively embedded into the inner cavity of the half of the fruit. A pitting channel is provided between the two protrusions for the pitting end of the pitting mechanism to pass through.

[0010] In one specific implementation, the pitting mechanism includes a base mounted on a second mounting frame, a support frame rotatably connected to the base, a second driving part for driving the support frame to rotate, and a pitting device for removing the pit from the inner cavity of the half of the fruit on the support frame.

[0011] In one specific implementation, the pitting device includes a sliding frame slidably connected to a support frame, the sliding frame being provided with spikes that remove the pit from half of the fruit through a pitting channel.

[0012] In one specific implementation, the support frame is provided with a first linear module, the slide of the first linear module is provided with a connecting frame, the connecting frame is provided with a drive cylinder, and the sliding frame is arranged on the slide of the drive cylinder.

[0014] In one specific implementation scheme, a material identification method based on the above-described material identification system is characterized in that the method includes: The positioning device is activated to limit half of the fruit onto the receiving mechanism; Activate the cavity-opening device to open the inner cavity of half of the fruit; Start the drive mechanism to drive the turntable to rotate, and rotate the receiving mechanism on the turntable to the position corresponding to the de-core mechanism; The second drive unit is activated to rotate the support frame, so that the spikes on the support frame correspond to the pit in the inner cavity of the fruit half; The drive cylinder is activated to move the sliding frame, causing the spiked block to pierce the inner cavity of the fruit half from below the receiving mechanism through the pit removal channel; After the spikes have penetrated the inside of the fruit pit, the drive cylinder is activated again to reset the sliding frame and remove the fruit pit from the inner cavity of the fruit.

[0015] In summary, this application has the following beneficial technical effects: When it is necessary to remove the pit from the inner cavity of the fruit half, the receiving mechanism receives the fruit half, and the drive mechanism is activated to drive the turntable to rotate and transport the receiving mechanism to the position corresponding to the pitting mechanism.

Detailed Implementation

[0022] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0023] This application discloses a material retrieval system.

[0024] Example 1 Reference Figure 1 and Figure 2 The material handling system includes a first mounting frame 1 and a second mounting frame 2. The first mounting frame 1 and the second mounting frame 2 can be integrally formed as a whole frame, or they can be designed separately. In this embodiment, the separate design is used as an example. The first mounting frame 1 is located on top of the second mounting frame 2.

[0025] Reference Figure 1 and Figure 2 A turntable 3 is rotatably connected to the first mounting frame 1. The first mounting frame 1 is equipped with a loading station 30, a de-core station 31, and a unloading station 32, depending on the actual situation. A receiving mechanism 4 is mounted on the turntable 3. The first mounting frame 1 also has a drive mechanism that drives the turntable 3 to rotate, sequentially moving the receiving mechanism 4 to the loading station 30, the de-core station 31, and the unloading station 32. In this embodiment, the drive mechanism can be a drive motor, with the turntable 3 located at the output end of the drive motor. The turntable 3 adopts a circular layout, arranging the loading station 30, the de-core station 31, and the unloading station 32 in a ring around the turntable 3, highly integrating the space requirements of each process.

[0026] In this embodiment, the number of receiving mechanisms 4 is set to three as an example. The turntable 3 has six mounting surfaces 34 along its rotation direction, and the three receiving mechanisms 4 are spaced apart on three of these mounting surfaces 34. Operators can also adjust the number of mounting surfaces 34 and receiving mechanisms 4 according to the mechanical rhythm of material production on site. Through the design of six evenly distributed mounting surfaces 34 and three spaced receiving mechanisms 4, when the turntable 3 rotates, the three receiving mechanisms 4 can sequentially cover the feeding, kernel removal, and unloading stations, matching the process rhythm of areca nut production and achieving continuous cyclic operation. Simultaneously, it optimizes the center of gravity distribution of the turntable 3, improving rotational stability.

[0027] Therefore, the rotation of turntable 3 replaces the long-distance movement of the robotic arm, requiring material transfer only within a circular area. This significantly shortens the longitudinal length of the production line and, compared to the flat conveyor lines in related technologies, substantially reduces the space occupied in the factory and improves production efficiency per unit area. Using turntable 3 to transport the fruit halves improves space utilization. Simultaneously, the periodic rotation of turntable 3 ensures that the receiving mechanism 4 arrives at each workstation sequentially at a fixed pace, reducing the transfer time of the fruit halves on the circular path. Each workstation operates synchronously around turntable 3, eliminating the redundant time of the robotic arm's back-and-forth movement, achieving highly efficient "on-demand processing" and improving overall production efficiency.

[0028] Reference Figure 1 and Figure 2The second mounting frame 2 is equipped with a pitting mechanism 5. The pitting mechanism 5 and the receiving mechanism 4 are staggered in the vertical direction, and the pitting mechanism 5 removes the pit from the half of the fruit from below the receiving mechanism 4. In this embodiment, the material pitting system can be applied to food materials, such as yellow peaches and areca nuts. In this embodiment, areca nuts are cut into two areca nut pieces by a cutting process, and the areca nut pieces are set on the processing station of the turntable 3 as an example.

[0029] Therefore, when it is necessary to remove the pits from the inner cavity of the areca nut slices, the receiving mechanism 4 receives the fruit half. In this embodiment, a robotic arm drives a needle to pierce the areca nut slices and feed them to the receiving mechanism 4. The drive mechanism is activated to rotate the turntable 3 and transport the receiving mechanism 4 to the pit removal station 31. At this time, the pit removal mechanism 5 and the receiving mechanism 4 are staggered in the vertical direction. The pit removal mechanism 5 removes the pits from the fruit half from below the receiving mechanism 4. Even if the pits accidentally fall off, it will not affect the normal conveying of the turntable 3, reducing the possibility of contaminating the conveyor belt or affecting other transmission components, reducing the risk of equipment jamming, reducing mechanical failures and downtime, and improving production efficiency.

[0030] Reference Figure 1 and Figure 3 The receiving mechanism 4 includes a positioning device and a cavity-opening device. The cavity-opening device has a receiving space 6. The positioning device pushes and positions the fruit half within the receiving space 6, and the cavity-opening device opens the inner cavity of the positioned fruit half. The positioning device includes a push rod 7 mounted on a turntable 3. The turntable 3 has a first driving unit that drives the push rod 7 to move. The first driving unit, when activated, pushes and positions the fruit half within the receiving space 6 via the push rod 7. In this embodiment, the first driving unit can be a cylinder, and the push rod 7 is located at the output end of the cylinder. A groove 33 matching the size of the areca nut slice is provided on the end face of the push rod 7 away from the cylinder. The groove 33 can be set to an arc shape according to the shape of the areca nut. The arc-shaped groove 33 limits the position of the areca nut slice, reducing the possibility of positional deviation. At the same time, the arc-shaped groove 33 adapts to the shape of the areca nut slice, reducing the possibility of damaging the areca nut slice during the movement of the push rod 7.

[0031] Reference Figure 1 and Figure 3The cavity-opening device includes an embedding unit. A drive unit is provided on the turntable 3 to drive the embedding unit to move. The embedding unit embeds into the fruit half and opens the inner cavity of the fruit half under the drive of the drive unit. The embedding unit includes at least two embedding components arranged opposite to each other on the turntable 3. In this embodiment, the number of embedding components is set to two groups as an example. Each group of embedding components includes two connecting frames 8 arranged on the drive unit. Each connecting frame 8 is fixedly connected to a protrusion 9. The two protrusions 9 are embedded into the inner cavity of the fruit half, and a pitting channel 19 is provided between the two protrusions 9 for the pitting end of the pitting mechanism 5 to pass through. The pitting channel 19 provides a stable operating space for the pitting end of the pitting mechanism 5 and reduces the risk of interference between the tool and the fruit pulp. The four protrusions 9 in the same group of embedding components are arranged opposite to each other in pairs, and each areca nut slice is located between the four protrusions 9.

[0032] Therefore, after the areca nut pieces are conveyed to the connecting frame 8, the first drive unit is activated, causing the push rod 7 at the output end of the first drive unit to extend and push the areca nut pieces against the protrusion 9. At this time, the protrusion 9 is embedded in the inner cavity of the fruit half, which further fixes the position of the areca nut pieces, reduces the possibility of the position of the areca nut pieces shifting during the cavity opening process, and improves the stability of the position of the areca nut pieces. In this embodiment, the example of the protrusion 9 being embedded in the inner cavity of the fruit half is used for illustration. In addition, the protrusion 9 can also be set as a curved bending block according to the actual situation on site. By increasing the friction between the bending block and the inner cavity of the areca nut pieces, the cavity opening of the inner cavity of the areca nut pieces can be further realized.

[0033] Reference Figure 1 and Figure 3 The drive unit includes a first moving frame 23 and a second moving frame 24 mounted on a mounting surface 34 on the outer periphery of the turntable 3. Two embedded components are respectively mounted on the first moving frame 23 and the second moving frame 24, that is, the connecting frame 8 and the protrusion 9 on the same side are both located on the first moving frame 23, while the connecting frame 8 and the protrusion 9 on the other side are both located on the second connecting frame 8. A drive assembly is provided on the mounting surface 34 to drive the first moving frame 23 and the second moving frame 24 to move relative to or away from each other. The drive assembly includes a gear 22 mounted on the mounting surface 34, and a third drive part is provided on the mounting surface 34 to drive the gear 22 to rotate. The third drive part can be a motor. A first rack 20 is bolted to the first moving frame 23, and a second rack 21 is bolted to the second moving frame 24. The gear 22 is located between the first rack 20 and the second rack 21, and the gear 22 meshes with the first rack 20 and the second rack 21 respectively. In this embodiment, a guide rail is bolted to the mounting surface 34, and a slider is slidably connected to the guide rail. The first moving frame 23 is bolted to the slider. The guide rail limits the movement direction of the slider, thereby improving the stability of the first moving frame 23 during movement. The second moving frame 24 can be configured with a guide rail and slider structure corresponding to the first moving frame 23.

[0034] Therefore, the third drive unit is activated, causing the gear 22 of the third drive unit to rotate. The rotation of the gear 22 causes the first rack 20 and the second rack 21 to move relative to or away from each other, thereby causing the first moving frame 23 and the second moving frame 24 to move relative to or away from each other. When it is necessary to clamp the areca nut pieces, the first moving frame 23 and the second moving frame 24 drive the connecting frame 8 and the protrusion 9 to move relative to each other, so that the areca nut pieces are clamped between the two connecting frames 8 located in the same group of embedded components, forming a receiving space 6 between the two connecting frames 8 located in the same group of embedded components. When it is necessary to open the inner cavity of the areca nut pieces, the third drive unit is activated again, and the first moving frame 23 and the second moving frame 24 drive the connecting frame 8 and the protrusion 9 to move away from each other. Since the protrusion 9 is embedded in the inner cavity of the fruit half, the protrusion 9 applies a force to the inner cavity of the areca nut pieces during the movement, opening the inner cavity of the areca nut pieces.

[0035] In this embodiment, a buffer unit is also provided on the mounting surface 34, and at least one embedded component is mounted on the drive unit through the buffer unit. The buffer unit includes a telescopic cylinder 25 mounted on the drive unit, and the embedded component is located at the output end of the telescopic cylinder 25. In this embodiment, two telescopic cylinders 25 are provided on the mounting surface 34, and the output ends of the two telescopic cylinders 25 are respectively bolted to a connecting frame 8. Therefore, the flexible contact of the buffer unit reduces hard collisions and reduces the possibility of damage to the surface of the areca nut during clamping. After the areca nut pieces are fed, they press against the output end of the telescopic cylinder 25. When dealing with large areca nut pieces, the output end of the telescopic cylinder 25 will slightly retract under force, reducing the possibility of excessive compression of the areca nut.

[0036] In this embodiment, when the pitting mechanism 5 removes the pits from the inner cavity of the areca nut slice, the protrusion 9 keeps the inner cavity of the areca nut slice open, optimizing the pit removal path and reducing pit residue. After the protrusion 9 is embedded in the inner cavity of the areca nut slice, it forms a physical limit, ensuring that the pit is always exposed within the operating range of the pit removal mechanism, reducing the problem of missed or incomplete pit removal due to accidental displacement. The protrusion 9 limits the inner cavity of the areca nut slice, and during the opening process, the protrusion 9 applies a uniform lateral force to the areca nut slice, counteracting the reaction force of the pitting mechanism 5 and preventing the material from sliding or rotating during the pit removal process. The arc-shaped groove 33 of the push rod 7 and the protrusions 9 on both sides form a "three-point clamping" effect, further enhancing the positioning reliability.

[0037] Reference Figure 1 and Figure 4The core removal mechanism 5 includes a base 10 mounted on a second mounting bracket 2. A support frame 11 is rotatably connected to the base 10. A second drive unit 12, which drives the support frame 11 to rotate, is mounted on the base 10. In this embodiment, the second drive unit 12 is a servo motor, and a reducer is mounted on the output end of the servo motor. The support frame 11 is mounted on the output end of the reducer. Therefore, activating the second drive unit 12 drives the support frame 11 to rotate relative to the base 10, making the angle of the support frame 11 and the core removal device on the support frame adjustable, thus improving the flexibility of the support frame 11.

[0038] Reference Figure 1 and Figure 4 The support frame 11 is equipped with a pitting device for removing the pit from the inner cavity of the fruit half. The pitting device includes a sliding frame 13 slidably connected to the support frame 11. In this embodiment, a first linear module 18 is installed on the support frame 11, and a connecting frame 17 is installed on the slide of the first linear module 18. The sliding frame 13 is slidably connected to the connecting frame 17. A finger cylinder 27 is installed on the sliding frame 13. In this embodiment, the finger cylinder 27 can also be an electric gripper, which is not limited here. A material picking block is bolted to the two slides of the finger cylinder 27. The material picking block includes a bent plate 35 set on the finger cylinder 27. A spike block 14 is fixedly connected to the end of the bent plate 35 away from the finger cylinder 27. The spike block 14 removes the pit from the fruit half through the pitting channel 19, that is, the spike block 14 is the pitting end of the pitting device. Therefore, starting the finger cylinder 27 causes the material-picking blocks on the two slides of the finger cylinder 27 to move relative to each other, thereby moving the two spike blocks 14. This allows for adjustment of the distance between the two spike blocks 14 according to the specific production specifications of the fruit halves on site, facilitating the pitting operation of fruit halves of different specifications and improving the applicability of the pitting device.

[0039] Reference Figure 1 and Figure 4 A drive cylinder 15 is mounted on the connecting frame 17 of the support frame 11. A sliding frame 13 is mounted on the slide of the drive cylinder 15. In this embodiment, the drive cylinder 15 is a slide cylinder, and the sliding frame 13 is mounted on the slide of the slide cylinder. A drive slide 16 is mounted on the sliding frame 13. In this embodiment, the drive slide 16 is specifically an electric slide. The finger cylinder 27 and the spike 14 are mounted on the moving slide of the electric slide, and the sliding direction of the drive slide 16 is perpendicular to the sliding direction of the drive cylinder 15. Therefore, in this embodiment, the first linear module 18 and the drive cylinder 15 move in the same direction, forming a two-stage adjustment, which further improves the movement range of the spike 14.

[0040] In addition, the second drive unit 12 is activated to drive the support frame 11 to rotate relative to the base 10, thereby coarsely adjusting the angle of the support frame 11 and the pitting device on the support frame 11. In this embodiment, the support frame 11 is tilted towards the pitting station 31 of the turntable 3. Subsequently, by sliding the moving end of the drive slide 16, the angle of the piercing block 14 into the inner cavity of the areca nut slice can be finely adjusted by ±10°. This makes it easier for the piercing block 14 to adjust the piercing angle according to the different positions of the kernels in the inner cavity of the areca nut slice, making the pitting block 14 more flexible in removing kernels and improving the applicability of the piercing block 14 to remove kernels from different positions. In this embodiment, two types of adjustments, coarse adjustment and fine adjustment, are used to optimize the insertion path. The coarse adjustment sets the reference angle and quickly adjusts the relative angle between the pitting device and the pitting station 31 of the turntable 3 by rotating the support frame 11 as a whole. This adapts to the initial position differences of different batches of materials or to meet the macroscopic adjustment needs of the layout of the turntable 3 station. The fine adjustment dynamically corrects the path by driving the slide table 16 to drive the piercing block 14 to make a fine adjustment of ±10°, accurately matching the actual position of the pit in half of a single fruit, and reducing the possibility of pitting failure due to individual differences in materials.

[0041] Reference Figure 1 and Figure 4 A crash shield 29 is bolted to the connecting frame 17. The finger cylinder 27 is located on the inner edge of the crash shield 29, and the material picking block passes through the crash shield 29. The crash shield 29 protects the finger cylinder 27 on the inner edge, reducing the possibility of accidental injury to the finger cylinder 27. A stripping plate 26 is provided on the crash shield 29. The stripping plate 26 is located between the two spike blocks 14. The stripping plate 26 acts as a blocking and limiting device for the fruit pit, facilitating the removal of the fruit pit from the spike blocks 14.

[0042] Reference Figure 1 and Figure 2 In this embodiment, the end of the connecting frame 17 facing the turntable 3 is bolted with a feeding tray 28. The feeding tray 28 is made of food-grade stainless steel and corresponds to the clamping end of the pitting device. In this embodiment, the feeding tray 28 is located below the pitting device, and baffles are fixedly connected to both sides of the feeding tray 28. After the pitting device completes the pitting process, the feeding tray 28 forms a directional dropping area, allowing the separated pits to fall naturally into the collection box below the feeding tray 28, facilitating the collection of the pits. The feeding tray 28 forms a physical isolation between the pitting mechanism 5 and the turntable 3, guiding the direction of pit feeding and blocking accidentally falling and splashing pits, reducing the probability of pits falling into the pitting mechanism 5 in a splashing state, further controlling the direction of pit splashing, reducing mechanical failures and downtime, and improving production efficiency.

[0043] The implementation principle of this application embodiment is as follows: When it is necessary to remove the kernel from the inner cavity of the areca nut slice, two areca nut slices are respectively transported by the robot arm of the feeding process in the related technology to the mounting surface 34 of the turntable 3 located at the feeding station 30. In the related technology, the moving end of the robot arm of the feeding process uses a needle to pick up the areca nut slice for transportation. When it is necessary to clamp the areca nut slice, the third drive unit is activated, which drives the gear 22 of the third drive unit to rotate. The rotation of the gear 22 drives the first rack 20 and the second rack 21 to move relative to each other, thereby causing the first moving frame 23 and the second moving frame 24 to move relative to each other. The areca nut slice is clamped between the two connecting frames 8 located in the same group of embedded components, and a receiving space 6 is formed between the two connecting frames 8 located in the same group of embedded components. The robot arm in the feeding process drives the needle to pull out, leaving the areca nut slice in the receiving space 6 formed between the two connecting frames 8. The first drive unit is activated, causing the push rod 7 at the output end of the first drive unit to extend and push the areca nut slice against the protrusion 9. At this time, the protrusion 9 is embedded in the inner cavity of the areca nut slice, which further limits the position of the areca nut slice. Then the third drive unit is activated again, and the first shift frame 23 and the second shift frame 24 drive the protrusion 9 to move in opposite directions. Since the protrusion 9 is embedded in the inner cavity of the fruit half, the protrusion 9 applies a force to the inner cavity of the areca nut slice during the movement, which opens the inner cavity of the areca nut slice, realizing the automatic opening of the fruit half, which facilitates the subsequent pitting process, saves time and labor and improves production efficiency. At this time, a pitting channel 19 is formed between the two protrusions 9 for the pitting end of the pitting mechanism 5 to pass through. Then the turntable 3 is controlled by the drive motor to rotate in increments. During the rotation of the turntable 3, the areca nut slice is transported to the pitting station 31 in sequence. When the areca nut slices are conveyed to the pitting station 31, the second drive unit 12 is activated to drive the support frame 11 to rotate relative to the base 10, thereby coarsely adjusting the angle of the support frame 11 and the pitting device on the support frame 11. The first linear module 18 is activated to extend the connecting frame 17 on the slide of the first linear module 18. The drive cylinder 15 is activated to extend the sliding frame 13 on the slide of the drive cylinder 15, so that the spike 14 on the sliding frame 13 pierces into the pit in the inner cavity of the areca nut slice through the pitting channel 19. Then, the drive cylinder 15 and the first linear module 18 are activated again to reset the sliding frame 13. During the movement, the pit on the spike 14 comes into contact with the stripping plate 26. At this time, the pit is located at the top of the feeding tray 28. The stripping plate 26 acts as a blocking and limiting device for the pit, removing the pit from the spike 14. The removed pit falls into the feeding tray 28 for feeding. Since the pitting mechanism 5 and the receiving mechanism 4 are staggered in the vertical direction, the pitting mechanism 5 removes the pit from the half of the fruit from below the receiving mechanism 4. Even if the pit falls off accidentally, it will not affect the normal conveying of the turntable 3, reducing the possibility of contaminating the conveyor belt or affecting other transmission components, reducing the risk of equipment jamming, reducing mechanical failures and downtime, and improving production efficiency.

[0044] Example 2 A method for obtaining material cores based on the above-mentioned material core-obtaining system, characterized in that the method includes: Step 1: The areca nut pieces are conveyed from the feeding process to the receiving mechanism 4 located at the feeding station 30; Step 2: Start the third drive unit, drive the gear 22 at the output end of the third drive unit to rotate. The rotation of the gear 22 drives the first rack 20 and the second rack 21 to move relative to each other, thereby causing the first moving frame 23 and the second moving frame 24 to move relative to each other, and the areca nut slices are clamped between the two connecting frames 8 located in the same group of embedded components. Step 3: Start the first drive unit, which will cause the push rod 7 at the output end of the first drive unit to extend and push the areca nut pieces against the protrusion 9. At this time, the protrusion 9 is embedded in the inner cavity of the fruit half. Step 4: Restart the third drive unit. The first shift frame 23 and the second shift frame 24 drive the protrusion 9 to move in opposite directions. The protrusion 9 opens up the inner cavity of the areca nut slice. Step 5: Start the drive motor to drive the turntable 3 at the output end of the drive motor to rotate in increments. During the rotation of the turntable 3, the areca nut pieces are transported to the pitting station 31. Step 6: After the receiving mechanism 4 on the turntable 3 delivers the material to the core removal station 31, the second drive unit 12 is started to drive the support frame 11 to rotate relative to the base 10, so as to achieve coarse adjustment of the angle of the support frame 11 and the core removal device on the support frame 11. Step 7: Start the first linear module 18 to extend the connecting frame 17 on the slide of the first linear module 18, and then start the drive cylinder 15 to extend the sliding frame 13 on the slide of the drive cylinder 15, so that the spikes 14 on the sliding frame 13 move toward the inner cavity of the areca nut slice. It should be noted that in step 7, the first mounting frame 1 is equipped with an image device, which includes an image acquisition unit and a data processing unit. The image acquisition unit includes a camera mounted on the mounting frame and corresponding to the half of the fruit. The camera captures the image information of the kernel in the inner cavity of the half of the fruit and transmits it to the data processing unit. The data processing unit determines the position information of the kernel based on the image information. If the thorn 14 is aligned with the kernel at this time, the thorn 14 on the sliding frame 13 will directly pierce the kernel in the inner cavity of the areca nut slice through the kernel extraction channel 19. If the thorn 14 is not aligned with the kernel at this time, the drive slide 16 will be activated. By sliding the moving end of the drive slide 16, the angle of the thorn 14 piercing the inner cavity of the areca nut slice can be finely adjusted by ±10°. The piercing angle of the thorn 14 is adjusted according to the position information of the kernel, so that the thorn 14 accurately pierces the inside of the kernel through the kernel extraction channel 19. Step 8: After the spike 14 pierces into the fruit pit, the drive cylinder 15 and the first linear module 18 are started again to drive the sliding frame 13 to reset. During the movement, the fruit pit on the spike 14 comes into contact with the stripping plate 26. The stripping plate 26 acts as a blocking and limiting device for the fruit pit, removing the fruit pit from the spike 14. The removed fruit pit falls into the feeding tray 28 for feeding.
