[0018] Exemplary embodiments of the present disclosure are described below with reference to the accompanying drawings, which include various details of the embodiments of the present disclosure to assist in understanding, and should be considered as merely exemplary. Therefore, those of ordinary skill in the art should recognize that various changes and modifications can be made to the embodiments described herein without departing from the scope of the present disclosure. Also, in order to be clear and concise, descriptions of well-known functions and structures are omitted in the following description.

[0019] As shown in Figure 1 , the present embodiment provides an impurity picking mechanism 100, comprising a rod body 1, a suction head 2, a vacuum tube 3 and a fixed part 4.

[0020] A conveying cavity 11 is formed inside the rod body 1, and the conveying cavity 11 communicates with a first end 12 and a second end 13 of the rod body 1. Among them, the first end 12 of the rod body 1 is the end close to the impurities when the impurity picking mechanism 100 works.

[0021] The suction head 2 is arranged at the first end 12 of the rod body 1, and the suction head 2 communicates with the conveying cavity 11.

[0022] The vacuum tube 3 communicates with the second end 13 of the rod body 1, and is used to provide suction force for the suction head 2. One end of the vacuum tube 3 communicates with the second end 13 of the rod body 1, and the other end of the vacuum tube 3 can communicate with a vacuum pump. The vacuum pump is used to drive the vacuum tube 3 to provide suction force for the suction head 2, so that the suction head 2 can use the vacuum force generated by high-speed airflow to suck the impurities into the conveying cavity 11 and then suck them out to the outside through the vacuum tube 3.

[0023] The fixed part 4 is arranged outside the suction head 2 and connected with the first end 12 of the rod body 1. A pressing plate 41 is arranged on the side of the fixed part 4 away from the first end 12 of the rod body 1. The pressing plate 41 is used to fix the impurities in the material to be picked, so as to prevent the impurities from being displaced by the force of the fixed part 4 or the picking part, and thus causing the picking part to fail to accurately pick the impurities. The pressing plate 41 is provided with a picking opening 42. The picking opening 42 is used to expose the impurities, so as to enable the suction head 2 to pick the impurities exposed in the picking opening 42. The side wall of the fixed part 4 is provided with at least one pressure relief opening 43. The pressure relief opening 43 is used to communicate the internal space of the fixed part 4 with the external space of the fixed part 4.

[0024] According to the embodiments of the present disclosure, it should be noted that:

[0025] As shown in Figure 1 and Figure 2 , the upper part of the structure shown in each figure is defined as the upper position, the lower part of the structure shown in each figure is defined as the lower position, the left side of the structure shown in each figure is defined as the left position, the right side of the structure shown in each figure is defined as the right position, the vertical direction between the upper part and the lower part of the structure shown in each figure is defined, and the horizontal direction between the left side and the right side of the structure shown in each figure is defined.

[0026] The material can be understood as bird's nest, tea, traditional Chinese medicine, tobacco or grain, etc., which is not limited here. The impurities can be understood as impurities in the material such as bird's nest, tea, traditional Chinese medicine, tobacco or grain, etc., which is not limited here.

[0027] The material, shape and size of the rod body 1 can be selected and adjusted as needed, which is not limited here. The conveying cavity 11 of the rod body 1 can be a straight line or a broken line cavity, which is not limited here. The first end 12 and the second end 13 of the rod body 1 can be two opposite ends, or two openings located in different spatial positions, which can be adjusted according to the shape of the rod body 1, which is not limited here.

[0028] The specific structure of the suction head 2 is not limited here, which can realize the suction of impurities from the material under the action of vacuum negative pressure.

[0029] The structure, material, shape and size of the fixed part 4 can be selected and adjusted as needed, which is not limited here. It can be realized that the impurities are pressed when picking the impurities, which can prevent the impurities from being displaced. The size of the pressing plate 41 and the caliber of the picking opening 42 can be selected and adjusted according to the size of the impurities. When the size of the impurities is large, the size of the pressing plate 41 and the caliber of the picking opening 42 can be increased correspondingly, so as to ensure that the impurities are picked out smoothly. When the size of the impurities is small, the size of the pressing plate 41 and the caliber of the picking opening 42 can be reduced correspondingly, so as to ensure that the impurities are picked out smoothly.

[0030] The vacuum pump can adopt any pump structure in the prior art, and no specific limitation is made herein. It is only required to provide suction force for the suction head 2 structure.

[0031] The shape, number, and arrangement position of the pressure relief port 43 on the fixed part 4 can be selected and adjusted as required, and no specific limitation is made herein. For example, the pressure relief port 43 can be provided as two, and the two pressure relief ports 43 are symmetrically arranged on the fixed part 4.

[0032] According to the technology of the embodiments of the present disclosure, the impurities in the material can be stably and further efficiently and accurately picked. The fine impurities floating in water are easy to drift with water. By arranging the fixed part 4, the impurities to be picked can be fixed, so that the impurities cannot be accurately picked when the impurities are displaced during picking in the picking part. The suction head 2 can quickly pick and suck out the impurities, which not only has high picking speed but also has high picking accuracy. In cooperation with the pressing plate 41 of the fixed part 4, the impurities fixed by the pressing plate 41 can be accurately picked out from the material. Since the pressure relief port 43 is arranged, when the impurities block the picking port 42 of the fixed part 4, the pressure relief port 43 can relieve the pressure in the internal space of the fixed part 4, thereby effectively preventing the suction head 2 from continuing to perform vacuum suction in the case that the impurities block the picking port 42, so that the fixed part 4 is not damaged due to excessive pressure.

[0033] In one example, the impurity picking mechanism 100 of the embodiments of the present disclosure can be applied to pick impurities in bird's nest. For example, fine impurities in the bird's nest silk after preliminary picking. Bird's nest is made of mixed down and saliva of silver-rimmed flying fox or the same species of swallow, and is considered as a high-grade tonic. High-quality bird's nest requires high cleanliness, and even clean bird's nest needs further cleaning. Bird's nest hair and various foreign matters need to be picked out from the bird's nest. Impurity picking of bird's nest is a necessary process before eating bird's nest with peace of mind. Before picking, the bird's nest needs to be divided into strips and scattered into silk, and soaked in water and laid on a carrier plate, so that various impurities can be picked out from the bird's nest by the suction head 2 of the impurity picking mechanism 100 of the embodiments of the present disclosure. The impurities that can be picked out from the bird's nest by the impurity picking mechanism 100 of the embodiments of the present disclosure include but are not limited to colored impurities such as bird's nest hair, small black particles, fibers, yellow silk, yellow bird's nest, wood chips, metal chips, stones, insects, and hair, and white impurities such as nails, paper scraps, plastic silk, plastic pieces, eggshells, egg whites, proteins, thread ends, foams, and bird's nest strips. In order to limit the loss of bird's nest silk caused by the vacuum suction of the suction head 2, the suction head 2 is provided with the fixed part 4 having the pressing plate 41, so that the bird's nest silk can be left on the carrier plate while the impurities are picked out.

[0034] In one example, the impurity picking mechanism 100 of the present disclosure can be a suction pen structure composed of a rod body 1 and a suction head 2. The rod body 1 serves as the pen barrel of the suction pen structure, and the suction head 2 serves as the pen head of the suction pen structure.

[0035] In one example, the outer edge of the suction head 2 can be circular. The pressing plate 41 can be in a ring structure.

[0036] In one embodiment, the impurity picking mechanism 100 further comprises a pressure sensor connected to the suction head 2 and / or the first end 12 of the rod body 1, for detecting the vacuum pressure value in the vacuum tube 3. When the pressure sensor detects that the vacuum pressure value is higher than the first pressure threshold, it indicates that the impurity picking mechanism 100 has a blockage of impurities. When the pressure sensor detects that the vacuum pressure value is lower than the second pressure threshold, it indicates that the vacuum tube 3 of the impurity picking mechanism 100 has a gas leakage.

[0037] According to the present disclosure, it should be noted that:

[0038] The pressure sensor can be any pressure detection device in the prior art, such as a vacuum negative pressure gauge, a differential pressure sensor, and an absolute pressure sensor.

[0039] According to the technology of the present disclosure, by setting the pressure sensor, the impurity picking mechanism 100 can be monitored in real time for blockage of impurities or damage and leakage of the vacuum tube 3, so that the impurity picking mechanism 100 can always operate in a good working state, and the efficiency of impurity picking is improved.

[0040] In one embodiment, the fixing part 4 is connected to the first end 12 of the rod body 1 through a first elastic member 44. The first elastic member 44 can adapt the fixing part 4 to the hardness of different materials, and at the same time, it can play a certain buffering role to prevent the fixing part 4 from damaging the materials.

[0041] Alternatively, the suction head 2 is connected to the first end 12 of the rod body 1 through a second elastic member 21. The second elastic member 21 can adapt the suction head 2 to the hardness of different materials, and at the same time, it can play a certain buffering role to prevent the suction head 2 from damaging the materials containing impurities when it suddenly extends through the picking port 42. For example, when the material is bird's nest, because the bird's nest is soft and fragile, if the suction head 2 moves too fast, the pressure when it contacts the bird's nest may crush or break the bird's nest, resulting in a decrease in the quality of the bird's nest.

[0042] According to the present disclosure, it should be noted that:

[0043] The first elastic member 44 and the second elastic member 21 can both be any component with deformation ability in the prior art, which is not limited here. For example, a spring, an elastic gasket, an elastic clasp, etc. can be used.

[0044] According to the technology of the embodiments of the present disclosure, by setting the first elastic member 44, the fixed part 4 can adapt to the hardness of different materials, and at the same time, play a certain buffering role to prevent the fixed part 4 from damaging the materials. By setting the second elastic member 21, the suction head 2 can be buffered, and the suction head 2 can adapt to materials of different hardness and texture when picking, so as to prevent the suction head 2 from damaging the integrity of the materials, and ensure that the suction head 2 can smoothly pick the impurities from the materials. At the same time, the setting of the second elastic member 21 can also avoid the damage of the suction head 2 caused by the unevenness of the tray on which the materials are placed.

[0045] In an embodiment, the suction head 2 is connected to the first end 12 of the rod body 1 through a first lifting mechanism, and the first lifting mechanism is used to drive the suction head 2 to reciprocate between a first direction and a second direction, wherein the first direction and the second direction are opposite.

[0046] When impurity picking is needed, the first lifting mechanism can be used to drive the suction head 2 to move along the first direction towards the picking port 42 of the fixed part 4, so that the suction head 2 picks the impurities from the picking port 42. When impurity picking is not needed, the first lifting mechanism can be used to drive the suction head 2 to move along the second direction towards the first end 12, so that the suction head 2 is away from the picking port 42.

[0047] According to the embodiments of the present disclosure, it should be noted that:

[0048] The first lifting mechanism can adopt any mechanism capable of driving the connected component (suction head 2) to reciprocate in the prior art, which is not limited here. For example, the first lifting mechanism can adopt a hydraulic rod, an air pressure rod, a gear and a rack, etc.

[0049] In order to ensure that the impurities can be picked cleanly, when the suction head 2 is controlled to move along the first direction towards the picking port 42, the pressing plate 41 of the fixed part 4 and the suction head 2 can be kept at a certain interval (2mm-4mm height difference), so that the impurities can smoothly enter the fixed part 4 through the picking port 42, and be smoothly transported to the outside through the vacuum pipe 3.

[0050] According to the technology of the embodiments of the present disclosure, by setting the first lifting mechanism, the position of the suction head 2 can be accurately controlled, and by changing the position of the suction head 2, the picking requirements of different picking modes and different types of impurities can be met. For example, when the picking mode is to suck the impurities, the first lifting mechanism can be used to control the suction head 2 to keep a certain interval with the picking port 42, so as to avoid that the suction force is too large to pick out the materials and impurities together.

[0051] In one example, the second elastic member 21 is arranged between the first lifting mechanism and the suction head 2.

[0052] In an embodiment, the suction head 2 is detachably arranged at the first end 12 of the rod body 1.

[0053] According to the technical solution of the embodiment of the present disclosure, since the suction head 2 is detachably connected with the first end 12 of the rod body 1, when impurities are blocked in the suction head 2, the suction head 2 can be replaced in time, so that the impurity picking work can continue to be carried out smoothly, and the picking efficiency of the impurities will not be affected due to the cleaning of the impurities in the suction head 2. In addition, different suction heads 2 can be replaced according to different sizes and types of impurities to meet the picking requirements of the impurities.

[0054] In an embodiment, the fixed part 4 is detachably arranged at the first end 12 of the rod body 1.

[0055] According to the technical solution of the embodiment of the present disclosure, since the fixed part 4 is detachably connected with the first end 12 of the rod body 1, when impurities are blocked in the picking port 42 of the fixed part 4 or inside the fixed part 4, the fixed part 4 can be replaced in time, so that the impurity picking work can continue to be carried out smoothly, and the picking efficiency of the impurities will not be affected due to the cleaning of the impurities in the fixed part 4. In addition, different fixed parts 4 can be replaced according to different sizes and types of impurities to meet the picking requirements of the impurities.

[0056] In an embodiment, the diameter of the pressing plate 41 is at least twice the caliber of the suction head 2, and / or the caliber of the suction head 2 is 1mm to 4mm.

[0057] As shown in Figure 2 and Figure 3 , the embodiment of the present disclosure provides an impurity picking device 200, which comprises a base 5 and an impurity picking mechanism 100.

[0058] At least two impurity picking mechanisms 100 of any embodiment of the present disclosure are slidably arranged on the base 5, and the at least two impurity picking mechanisms 100 reciprocate between a first direction and a second direction relative to the base 5. The caliber of the suction head 2 of each of the at least two impurity picking mechanisms 100 is different, and different sizes of impurities are picked by the suction heads 2 with different calibers.

[0059] According to the embodiment of the present disclosure, it should be noted that:

[0060] The first direction, as shown in Figure 2 , can be understood as the direction in which the suction head 2 moves vertically downward.

[0061] The second direction, as shown in Figure 2 , can be understood as the direction in which the suction head 2 moves vertically upward.

[0062] The base 5 is used to fix at least two impurity picking mechanisms 100. When the impurity picking device 200 needs to be used in cooperation with other equipment, the base 5 is also used to mount the at least two impurity picking mechanisms 100 on the corresponding matched equipment. The specific structure, shape, size and material of the base 5 can be selected and adjusted as needed, and are not specifically limited here.

[0063] The number of impurity picking mechanisms 100 can be selected and adjusted as needed, and is not specifically limited here. It mainly depends on the picking mode and the size requirement of the picked impurities. For example, when the impurities are classified into two size levels of large and small, the impurity picking mechanism 100 can be two. When the impurities are classified into three size levels of large, medium and small, the impurity picking mechanism 100 can be three.

[0064] The impurity picking mechanism 100 is slidably arranged on the base 5, which can be understood as that the impurity picking mechanism 100 can perform a sliding motion relative to the base 5. Each impurity picking mechanism 100 can be movable relative to the base 5 respectively, or can be linked together. For example, a plurality of impurity picking mechanisms 100 can perform impurity picking operations together. For another example, one impurity picking mechanism 100 performs an impurity picking operation, and the remaining impurity picking mechanisms 100 do not perform impurity picking operations.

[0065] According to the technology of the embodiments of the present disclosure, by arranging at least two impurity picking mechanisms 100, different suction heads 2 can be driven to pick impurities according to different impurity forms, so as to reduce picking loss. Different sizes of impurities are continuously picked in one impurity picking process, the machine downtime time of impurity picking is reduced, and the picking efficiency, continuous picking speed and picking precision of impurities are improved. Especially for materials with high impurity density, the arrangement of at least two impurity picking mechanisms 100 in the embodiments of the present disclosure can significantly improve the picking efficiency of impurities.

[0066] In one example, the number of impurities in 10g (grams) of bird's nest can be as high as several hundred. If the force is not controlled properly, single-point multiple picking will cause serious damage to the integrity of the bird's nest silk, and each picking may also take away a part of the bird's nest, resulting in large mechanical picking loss. This is the biggest pain point for bird's nest manufacturers to introduce large-scale mechanical picking. To solve the above problems, the embodiments of the present disclosure use suction pens with different small diameters for precise suction. Whether the impurities are free, attached to the bird's nest silk, or condensed inside the bird's nest silk, the impurity picking device 200 of the embodiments of the present disclosure can accurately and efficiently pick out the impurities. At the same time, under the action of the pressing plate 41, the suction head 2 can cause less damage to the bird's nest silk, and the picking rate is higher. Especially for cleaning various small impurities, the effect is remarkable, and it can completely replace manual operation.

[0067] In an embodiment, the impurity picking device 200 further comprises a water spraying mechanism 6, including a nozzle 61 and a pipeline 62, the nozzle 61 is connected with the base 5, the pipeline 62 is connected with the nozzle 61, and the pipeline 62 is used for conveying liquid to the nozzle 61. The nozzle 61 is used for spraying the liquid conveyed in the pipeline 62. The pipeline 62 can be connected with a water pump, and the liquid is conveyed to the nozzle 61 through the pipeline 62 by the water pump.

[0068] When the material is bird's nest or other material that needs to be picked in a wet state, in order to avoid the drift of the position of impurities caused by water replenishment, the nozzle 61 is used for water replenishment when the fixed part 4 is lowered. Before picking, the bird's nest is divided into 1mm-3mm thick bird's nest silk, which is wetted with water, and is evenly laid on the carrier disc in a single layer. The water depth of the carrier disc is appropriate to the bird's nest silk. The impurity picking mechanism 100 will take away part of the water each time, and the water replenishment of the water spraying mechanism 6 can maintain the humidity of the carrier disc, so as to facilitate the picking of impurities.

[0069] According to the technology of the embodiment of the present disclosure, by setting the water spraying mechanism 6, the water replenishment of the material can be timely, and the success rate of picking impurities in the material can be improved.

[0070] In an example, the type of nozzle 61 is not specifically limited here, and can be selected and adjusted as needed, for example, a water mist nozzle, a shower head, etc. can be used.

[0071] In an embodiment, the impurity picking device 200 further comprises a third elastic member 7, which is arranged at a position close to the second direction of the base 5. The third elastic member 7 corresponds to the positions of the at least two impurity picking mechanisms 100, and in the case that any of the at least two impurity picking mechanisms 100 moves towards the second direction, the third elastic member 7 is in contact with the any impurity picking mechanism 100.

[0072] According to the embodiment of the present disclosure, it should be noted that:

[0073] The third elastic member 7 can use any component with deformation ability in the prior art, which is not specifically limited here. For example, a spring, an elastic gasket, an elastic spring, etc. can be used.

[0074] According to the technology of the embodiment of the present disclosure, the third elastic member 7 can adapt the hardness of different materials to the impurity picking mechanism 100, and at the same time, it can play a certain buffering role. In addition, when the flatness of the carrier disc containing the material is poor, the third elastic member 7 can buffer the impact force of the carrier disc on the suction head 2, and avoid the passivation of the suction head 2.

[0075] In an embodiment, each of the at least two impurity picking mechanisms 100 is liftably connected to the base 5 through a transmission mechanism, which includes a slide rail 8 arranged on the base 5, and each of the impurity picking mechanisms 100 is slidably connected to the slide rail 8 to enable reciprocating movement of each of the impurity picking mechanisms 100 relative to the base 5. The slide rail 8 is used to guide the impurity picking mechanisms 100 to move in the vertical direction towards the first direction and the second direction.

[0076] According to the embodiments of the present disclosure, it should be noted that:

[0077] The impurity picking mechanisms 100 can be linked through the transmission mechanism, so that one of the at least two impurity picking mechanisms 100 moves in the first direction for impurity picking while the rest of the impurity picking mechanisms 100 moves in the second direction, wherein the first direction is opposite to the second direction.

[0078] The structure of the slide rail 8 can be selected and adjusted as needed. For example, the slide rail 8 can be a strip-shaped groove arranged on the base 5 and recessed in the base 5. For another example, the slide rail 8 can be a strip-shaped protrusion arranged on the base 5 and protruding from the base 5.

[0079] According to the technology of the embodiments of the present disclosure, the impurity picking mechanisms 100 are connected through the transmission mechanism, so that the impurity picking mechanisms 100 can be simultaneously linked to ensure that the impurity picking mechanism 100 performing the impurity picking action moves in the first direction towards the impurities while the rest of the impurity picking mechanisms 100 not performing the impurity picking action moves in the second direction away from the impurities to avoid interference of the impurity picking mechanism 100 not performing the impurity picking action on the impurity picking mechanism 100 performing the impurity picking action. By arranging the slide rail 8 on the base 5, the impurity picking mechanisms 100 driven by the transmission mechanism can be guided to accurately move to the position corresponding to the picking opening 42 of the fixed part 4, thereby achieving impurity picking.

[0080] In an embodiment, each of the impurity picking mechanisms 100 is connected to the slide rail 8 through a sliding piece 81, and a second lifting mechanism 82 is arranged between each of the impurity picking mechanisms 100 and the sliding piece 81, and the second lifting mechanism 82 is used to drive each of the impurity picking mechanisms 100 to reciprocate between the first direction and the second direction.

[0081] According to the embodiments of the present disclosure, it should be noted that:

[0082] The second lifting mechanism 82 can be any mechanism capable of driving the connected components to reciprocate in the prior art, which is not specifically limited here. For example, the second lifting mechanism 82 can be a hydraulic rod, a hydraulic cylinder, a pneumatic rod, a pneumatic cylinder, a gear and rack mechanism, etc.

[0083] According to the technology of the embodiments of the present disclosure, the position of the suction head 2 can be accurately controlled by setting the second lifting mechanism 82, and by changing the position of the suction head 2, the picking requirements of different picking modes and different types of impurities can be met. For example, when the picking mode is to suck the impurities, the suction head 2 can be controlled to maintain a certain interval from the picking port 42 by the second lifting mechanism 82, so as to avoid that the suction force is too large to pick out the material and the impurities together.

[0084] In an embodiment, the sliding piece 81 is connected with the motor 83, and the motor 83 is used to drive the sliding piece 81 to slide along the slide rail 8.

[0085] According to the embodiments of the present disclosure, it should be noted that:

[0086] The motor 83 can adopt any motor 83 structure in the prior art, which is not specifically limited here, and can drive the sliding piece 81 to slide along the slide rail 8. For example, the motor 83 can adopt a linear motor or a servo motor, etc.

[0087] According to the technology of the embodiments of the present disclosure, by driving with the motor 83, the impurity picking mechanism 100 can be driven at a very high acceleration to translate at a high speed, thereby improving the picking efficiency of a single impurity picking mechanism 100.

[0088] In an embodiment, as shown in Figure 2 The impurity picking device 200 further comprises an image acquisition device 9 arranged on the base 5 and used for acquiring images of the impurities in the material. The image acquisition device 9 can acquire images of the surrounding area of the picked impurities in real time during the picking of the impurities by the impurity picking mechanism 100, so as to better observe whether the impurity picking mechanism 100 accurately picks the impurities and whether the impurities are picked clean. The image acquisition device 9 can also be used before the impurity picking mechanism 100 picks the impurities, to pre-acquire images of the material to be picked, and then identify the impurities to be picked from the images, so that the impurity picking mechanism 100 can pick the identified impurities.

[0089] According to the embodiments of the present disclosure, it should be noted that:

[0090] The setting position of the image acquisition device 9 on the base 5 can be selected and adjusted as needed, as long as the acquisition field of view of the image acquisition device 9 is not interfered by the impurity picking mechanism 100. The image acquisition device 9 can adopt any shooting device in the prior art, which is not specifically limited here. For example, the image acquisition device 9 can adopt a camera, a camera, etc.

[0091] According to the technology of the embodiment of the present disclosure, by setting the image acquisition device 9, accurate identification of impurities in the material can be realized, and real-time observation of the picking of impurities can be realized when the impurity picking mechanism 100 picks the impurities.

[0092] In an embodiment, the image acquisition end of the image acquisition device 9 is externally provided with a protective cover. The protective cover is used to protect the image acquisition end, so as to avoid the image acquisition end from being blocked by impurities, liquid or dust to collect the field of view.

[0093] According to the embodiment of the present disclosure, it should be noted that:

[0094] The specific structure, shape and size of the protective cover can be adjusted according to the image acquisition end, which can ensure that the protective cover is arranged outside the image acquisition end and does not interfere with the image acquisition end.

[0095] According to the technology of the embodiment of the present disclosure, by setting the protective cover, the collection field of view of the image acquisition end of the image acquisition device 9 can be avoided to be blocked by impurities, liquid or dust from the outside, and the accuracy of image acquisition is improved.

[0096] In one example, the impurity picking mechanism 100 of the embodiment of the present disclosure can adopt a suction pen structure, the pen head (suction head 2) of the suction pen structure can be circular, the fixed part 4 at the periphery of the pen head is provided with a ring-shaped pressing plate 41 which does not contact the pen head, and the pen body (rod body 1) is connected with the vacuum pipe 3 to generate vacuum force by high-speed airflow to suck the impurities. The impurity picking mechanism 100 of the embodiment of the present disclosure is suitable for clean bees which have been preliminarily picked, and the main picking target is small impurities. The diameter of the suction pen head is 1-4 mm, and the outer diameter of the pressing plate 41 is about twice the diameter of the pen head. Since the same length of the pen head edge and the circular area are the largest, and the impurities in the bee nest are mostly black spots and bee hairs, the loss of the small hole diameter circular suction pen is the lowest. The design of the pressing plate 41 can fix the bee silk around the impurities when the suction pen contacts the vacuum suction plate to further reduce the loss. The pressure relief holes are left on the side edges of the pressing plate 41, which can balance the air pressure, effectively reduce the risk of suction pen blockage, and avoid the secondary pollution of the bee nest caused by the impurities remaining in the pen head.

[0097] In one example, the impurity picking device 200 of the present embodiment can be configured with two suction pen structures of the impurity picking mechanism 100. The pen head and the pressing plate 41 of the suction pen can be replaced according to the actual material to be picked. Two suction pen positions can be respectively installed with a large and a small pen head for picking impurities of different sizes. On the distribution density graph of impurity diameter, the positions corresponding to the diameters of the two suction pen openings are obviously different. Different suction pens are driven according to the size of the impurities to pick, which can better balance the success rate and loss rate of picking. At least one of the suction pen positions is equipped with a gas cylinder (second lifting mechanism 82). When on standby, the impurity picking mechanism 100 is kept at a high position, with the suction pen position with the gas cylinder on top and the other suction pen position on the bottom. When picking, the impurity picking mechanism 100 is lowered, and the suction pen with the gas cylinder is also lowered when the suction pen is working, the suction pen is on the bottom, and the suction pen without the gas cylinder is on the top. Conversely, when the suction pen without the gas cylinder is working, the gas cylinder remains contracted, the suction pen is on the bottom, and the suction pen with the gas cylinder is on the top. Only one suction pen contacts the impurities for picking operation each time. The third elastic member 7 is arranged at the upper end of the slide rail 8, which can buffer the impact force of the pen head on the load plate when the flatness of the load plate is poor, and avoid the dulling of the pen head. The impurity picking device 200 of the present embodiment adopts double suction pen alternating operation, one group is a large suction pen and the other group is a small suction pen. For example, when the pen head diameter of the small suction pen is 1.5 mm, if the diameter of the impurities is greater than 1.5 mm or the distance between two impurities is greater than 1.5 mm, a large suction pen will be used for suction. Conversely, if the diameter of a single impurity is less than 1.5 mm, a small suction pen will be used for suction. The two are used alternately according to the picking mode matched with the coordinates. According to the impurities identified in the image collected by the image acquisition device 9, high-speed continuous picking is performed. Compared with the ordinary single suction pen in the past, the loss can be reduced more, and various foreign matters can be adapted. According to the actual measurement, black spots, swallow feathers, fibers, hair, small stones, iron filings and other types of small impurities can be picked out.

[0098] In one example, the impurity picking mechanism 100 of the suction pen structure of the present disclosure can perform suction, blowing, and stopping. The airflow passes through the vacuum tube 3 at the tip of the suction pen at high speed. Compared with other types of vacuum equipment, the vacuum tube 3 is light, the vacuum response is fast, and it is easy to install and replace. The vacuum pressure of the structure can reach-90 KPa (kiloPascal), which is sufficient to ensure the suction force of the tip on the impurities. The tip tail end is equipped with a vacuum negative pressure table (pressure sensor) for real-time monitoring. If the negative pressure is out of limit, the tip is blocked. If the negative pressure is insufficient, the pipeline leaks. The impurity picking mechanism 100 of the present disclosure can realize vacuum suction. In order to generate sufficient negative pressure, the impurity picking mechanism 100 uses the vacuum tube 3 to generate sufficient suction force through a higher airflow. Compared with other types of vacuum equipment, the characteristics are: fast vacuum response, simple and light structure, vacuum pressure up to-90 KPa, direct piping, easy to install and replace. At the same time, real-time monitoring is performed by the vacuum negative pressure table (pressure sensor), which ensures that the suction head 2 is not blocked. In order to distinguish impurities of different sizes, each impurity picking mechanism 100 can be connected with a vacuum tube 3. The advantages of this method are that the two do not interfere with each other, there is no air leakage, and the impurities are easy to distinguish. The impurities sucked by the two groups of air paths are respectively recovered by the two groups of recovery devices.

[0099] In one example, the impurity picking device 200 of the present disclosure is configured with an automatic water replenishing device (water spraying mechanism 6) composed of a nozzle, a water pipe, and a pump body. In order to avoid water replenishment causing the position of impurities to drift, the automatic water replenishing device sprays water when the suction pen is descending. Before picking, the bird's nest is cut into 1-3 mm thick bird's nest silk, which is moistened with water and evenly laid in a single layer on the loading tray. The water depth of the loading tray is appropriate relative to the bird's nest silk. If the water is too much, the impurities near the periphery of the pressing plate 41 during the operation of the suction pen are easy to move horizontally. If the water is too little, the impurities, especially the bird's nest hair, are easy to adhere to the loading tray and not easy to be sucked away. The suction pen will take away part of the water each time it operates, and the automatic water replenishing device replenishes water to maintain the humidity of the loading tray. Since the water is added at a low height, the water mist is close to the bird's nest, so it will not affect the image acquisition of the image acquisition device 9.
