Description

Technical Field

[0001] The invention relates to the technical field of embryo egg inspection, and in particular to an embryo egg automatic inspection system and a control method thereof. Background Art

[0002] In the prior art, the allantoic fluid of the inoculated and cultured embryonated eggs needs to be extracted for vaccine production.

[0003] The embryo egg allantoic fluid collection device in the prior art still has the following defects and shortcomings in actual use: 1) The different sizes of embryo eggs make the embryo eggs placed at different heights on the egg tray, while the top limiting plate for the embryo eggs is at the same height, and the knife plate for shelling is also at the same height. This arrangement makes it possible that: when the heights of the top limiting plate and the shelling knife plate match the eggs with a higher height, the eggs with a higher height can be limited and shelled successfully, while the limiting pressing force on the eggs with a lower height is too small, so the shelling will fail during the shelling process; and when the heights of the top limiting plate and the shelling knife plate match the eggs with a lower height, the limiting pressing force and shelling force on the eggs with a higher height will be too large, which will cause the eggs with a higher height to be cut, crushed, collapsed, and other damages during the egg lifting process or the shelling process.

[0004] 2) In the prior art, it is necessary to manually check the embryo eggs after shelling, remove unqualified embryo eggs, and then replenish eggs to put qualified embryo eggs into the empty space in the egg tray, so as to facilitate the subsequent extraction of allantoic fluid.

[0005] 3) In addition, all existing harvesting heads adopt a unified rising or falling working mode to harvest all the allantoic fluid of all embryonic eggs entering the harvesting station. For unqualified embryonic eggs, the harvesting head will be contaminated after obtaining the allantoic fluid, which will affect the collection of the allantoic fluid of qualified embryonic eggs in the subsequent egg tray. In order to avoid this situation, it is necessary to remove the unqualified embryonic eggs after shelling in advance after detecting the unqualified embryonic eggs, and then fill the empty space in the egg tray. The complicated process affects the automation efficiency.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0034] [First embodiment] like Figure 1-8 FIG. 1 is a device for collecting allantoic fluid from embryonated eggs provided by the first embodiment of the present invention, Figure 1-2 As shown, it includes a tray feeding unit 1, an egg lifting unit 2, a shelling unit 3, a detection unit 4, a harvesting unit 5 and a tray discharging unit 6 which are sequentially arranged along the egg tray transmission direction, and the control system is respectively connected with the tray feeding unit 1, the egg lifting unit 2, the shelling unit 3, the detection unit 4, the harvesting unit 5 and the tray discharging unit 6 by signals so as to control the actions of each unit accordingly; The tray feeding unit 1 delivers the egg tray containing embryonated eggs horizontally to the position of the egg lifting unit 2; Figure 1-2 As shown, the tray-feeding unit 1 in this embodiment can be configured to include a tray-feeding bracket 11 and a tray-feeding platform 12 fixedly arranged on the top of the tray-feeding bracket 11, a roller is arranged at the bottom of the tray-feeding bracket 11 to facilitate the overall movement and transportation of the tray-feeding bracket 11, and a tray-feeding conveyor 13 is arranged on the top of the tray-feeding platform 12. The tray-feeding conveyor 13 can use a driving wheel driven by a power source and a driven wheel connected to the driving wheel through a conveyor belt wrapped around the outside, the power source drives the driving wheel to rotate and then drives the conveyor belt thereon to move to realize the transportation of the egg tray on its top, thereby horizontally delivering the egg tray containing embryonated eggs from the tray-feeding unit 1 to the egg lifting unit 2 position.

[0035] The egg lifting unit 2 lifts the embryo eggs in the egg tray at the current position to the working height of the shelling unit 3, and the shelling unit 3 shells the embryo eggs at the current working height position. After the shelling is completed, the egg lifting unit 2 falls back and drops the shelled embryo eggs back into the egg tray, and then the embryo egg tray is delivered to the position of the detection unit 4 by the intermediate transmission component.

[0036] like Figure 3-4 As shown, the egg lifting unit 2 in the present embodiment comprises a base plate 21 fixed to a frame, a lifting cylinder 22 is fixed on the top of the base plate 21, the output end of the lifting cylinder 22 is fixedly connected to the top top plate 23, the top plate 23 can move up and down relative to the base plate 21 along the guide assembly 24 under the driving of the lifting cylinder 22, the top of the top plate 23 is lifted by the egg lifting assembly 25 to the embryo eggs in the egg tray A, and the top plate 23 can realize lifting movement along a predetermined vertical direction relative to the base plate 21 by setting the guide assembly 24, so as to avoid unexpected deviation and thus have an adverse effect on the transportation of the top egg tray A; by being provided with the egg lifting assembly, the embryo eggs of different heights can be subjected to equal position limiting in the guide hole plate; the embryo eggs of different sizes and heights can be directly placed in the egg tray, and there is no need to pre-classify the embryo eggs entering the inoculator; there is no need to readjust the pressing force of the embryo eggs entering the harvester in advance because of the different heights of the embryo eggs.

[0037] like Figure 3As shown, the guide assembly 24 in this embodiment includes a guide rod 241 fixed to the top of the bottom plate 21, and a sleeve 242 is fixedly provided at the bottom of the top plate 23. The top plate 23 and the sleeve 242 are mounted on the outer periphery of the guide rod 241 in a liftable manner, and a limit piece 243 extending radially along the guide rod 241 is also fixed to the top of the guide rod 241. When the top plate 23 and the sleeve 232 are mounted on the outer periphery of the guide rod 241 and rise relative to the bottom plate 21 to the position of the limit piece 243, the top of the top plate 23 will touch the bottom of the limit piece 243 to limit the highest rising position of the top plate 23. Preferably, the limit piece 243 can be located at different height positions on the top of the guide rod 241 to achieve a limiting effect on the top plate 23 rising to different highest positions.

[0038] like Figure 4 As shown, the egg-top assembly 25 in the present embodiment comprises a pressure device 251, which is arranged on the top of the top plate 23 and corresponds to the position of each embryo egg in the egg tray A. The pressure device 251 can provide corresponding different lifting pressures for the difference in the height of each embryo egg B, so that each embryo egg can make the embryo egg top be located at the same height position in the guide hole plate 253 under the lifting effect of the pressure device 251. Preferably, in the present embodiment, the total pressure provided to all pressure devices 251 can be set to a constant value, and the required lifting strokes provided for the different heights of each embryo egg B are different from each other (the required lifting strokes for the higher embryo eggs are relatively small, while the required lifting strokes for the lower embryo eggs are larger), so the extra pressure at the higher embryo egg position can be distributed to the lower embryo egg position for use through the trachea, thereby further improving the working efficiency of the pressure device 251; as encountering a lot of situations of higher embryo eggs, the total pressure can be maintained constant by the mode of total gas path pressure relief (the situation of encountering a lot of lower embryo eggs is then adopted the supercharging mode).

[0039] The top extended end of the pressure device 251 is fixedly provided with an egg-supporting elastic member 252, which conflicts with the bottom of each embryo egg in the egg tray A. The egg-supporting elastic member 252 can be preferably an elastic member such as rubber, so as to reduce the possible extrusion damage to the embryo egg by the conflict between the egg-supporting elastic member 252 and the bottom of the embryo egg as much as possible; A guide hole plate 253 is also provided at the top of the egg tray A, and the internal through hole of the guide hole plate 253 corresponds to the position of each embryo egg in the egg tray A, so that the top of the embryo egg with different heights can be limited in the internal through hole of the guide hole plate 253 by arranging the guide hole plate 253, so that the top of the embryo egg with different heights is located at the same working plane, thereby facilitating the subsequent overall shelling action; As the further preferred embodiment of the present invention, the internal through hole of the guide hole plate 253 is set to a tapered hole with a small top and a large bottom, so as to adapt to the top structural shape of the embryo egg, thereby further improving the positioning stability of the embryo egg top in the guide hole plate 253 inside.

[0040] like Figure 5 As shown, the shelling unit 3 in this embodiment includes a shelling cylinder 31 fixed to one side of the frame, the protruding end of the shelling cylinder 31 is fixedly connected to the knife plate 32, and shelling tracks 33 are arranged on both sides of the top of the guide hole plate 253. The knife plate 32 moves along the shelling track 33 under the drive of the shelling cylinder 31 to realize the overall shelling action of the top of the embryo egg higher than the guide hole plate 253. The shelling cylinder 31 in this embodiment is preferably a two-way driving cylinder to realize the retraction of the knife plate 32 to the original position after the shelling action is completed.

[0041] In order to facilitate the collection of eggshells after shelling, a shell blowing assembly 26 is provided on the other side of the frame. The shell blowing assembly 26 includes a shell blowing device 261 connected to an external power source and a shell collecting pipe 262 extending to the outside of the frame. The shell blowing device 261 is connected to the inside of the shell collecting pipe 262. The eggshells that fall off after shelling enter the inside of the shell collecting pipe 262 under the blowing of the shell blowing device 261, and then the eggshells are uniformly discharged. Preferably, in this embodiment, the shell cutting unit 3 is arranged on one side of the frame, and the shell collecting pipe 262 is correspondingly arranged on one side of the frame near the position where the blade 32 extends out, so as to be as close as possible to the position where the eggshells remain after shelling, thereby improving the shell collecting efficiency; the shell blowing device 261 is arranged on the front and rear sides of the frame and near the position where the blade 32 is retracted, so that the wind force blown by the shell blowing device 261 can help drive the outer eggshells into the inside of the shell collecting pipe 262.

[0042] The detection unit 4 identifies the shelled embryo eggs through the detection model created by deep learning, and sends the identification result to the harvesting unit 5. After the detection is completed, the intermediate transmission component sends the egg tray to the location of the harvesting unit 5; in the present embodiment, the detection unit 4 obtains the image of the shelled embryo eggs in real time, and identifies the image of the shelled embryo eggs through the detection model created by deep learning, and sends the identification result to the harvesting unit 5, so as to replace the manual inspection of the embryo eggs, thereby avoiding the mistakes caused by human factors; at the same time, it can also avoid the contamination of the embryo eggs by the production personnel, and further improve the cleanliness of the embryo eggs; in addition, it can also avoid the risk of production personnel being infected by embryo egg viruses.

[0043] like Fig.10 As shown in the figure, some actual embryo eggs are identified as examples. In this embodiment, after the shelling is completed, the identification results show that the embryo eggs that are not unqualified include but are not limited to ( Fig.10 The embryo eggs at each position are numbered as follows: 1-6 rows vertically and 1-6 horizontally): 1) The eggshell of the embryo is not cut at the air chamber end, as shown in the figure, No. 1 in row 2 and No. 1 in row 4; 2) The eggshell at the air chamber end has been cut off and the embryo is small, such as No. 5 in row 1 and No. 6 in row 3 in the figure; 3) The cut eggshells fall into the embryonic eggs at the end of the air chamber, as shown in the figure, No. 1 in row 1 and No. 2 in row 4; 4) Broken and collapsed embryo eggs, such as No. 2 in row 3 and No. 6 in row 6; 5) There are no embryonated eggs in the egg cells of the egg tray, as shown in the picture, No. 6 in row 2 and No. 1 in row 3.

[0044] The harvesting unit 5 collects the allantoic fluid of the embryonated eggs that pass the test according to the identification result, and refuses to collect the embryonated eggs that fail the test. After the collection is completed, the intermediate conveying component sends the embryonated egg tray to the location of the tray output unit 6.

[0045] like Figure 6-8 As shown, the harvesting unit 5 in this embodiment includes a harvesting lifting cylinder 51 fixed to the top of the frame, and the bottom protruding end of the harvesting lifting cylinder 51 is fixedly connected to the harvesting action component 52, so that the overall lifting action of the bottom harvesting action component 52 is realized through the harvesting lifting cylinder 51.

[0046] The harvesting action assembly 52 includes a harvesting action cylinder 521, which is fixed to the bottom of the extended end of the harvesting lifting cylinder 51. The bottom end of the bottom telescopic shaft 522 of the harvesting action cylinder 521 is fixedly connected to the harvesting head 523. The harvesting head 523 can enter the embryo egg B to collect the allantoic fluid under the drive of the harvesting action cylinder 521. The harvesting head 523 can use a suction device to extract the allantoic fluid on the top of the embryo egg. Compared with the improvement of the prior art, in the present embodiment, a plurality of harvesting action cylinders 521 are evenly arranged at the bottom of the harvesting lifting cylinder 51 and correspond to the position of each embryo egg in the egg tray A, and each harvesting action cylinder 521 can act independently according to the detection result of the identification unit 4, so that only the allantoic fluid of qualified embryo eggs is collected, and the allantoic fluid of embryo eggs that fail the detection is refused to be collected, thereby reducing the possibility of the harvesting head being contaminated after obtaining the allantoic fluid, thereby affecting the collection of the allantoic fluid of qualified embryo eggs in the subsequent egg tray. At the same time, there is no need to remove the unqualified embryo eggs after shelling in advance and then fill the empty space in the egg tray, which saves working procedures and improves automation efficiency.

[0047] Finally, the egg tray containing the collected embryo eggs is sent out horizontally through the tray discharging unit 6. The tray discharging unit 6 can adopt the same internal structure and working principle as the tray feeding unit 1, which will not be repeated here.

[0048] [Second embodiment] The second embodiment of the present invention further provides a control method for the device for collecting allantoic fluid from embryonated eggs in the first embodiment, comprising the following steps: S1: The tray feeding unit 1 delivers the egg tray containing embryonated eggs horizontally to the position of the egg lifting unit 2; S2: The egg lifting unit 2 lifts the embryo eggs in the egg tray at the current position to the working height of the shell cutting unit 3, so as to facilitate the subsequent egg lifting action. In this process, the overall limiting effect of the lifting action is achieved through the guide component 24; S3: the egg lifting assembly 25 lifts the embryonated eggs B in the egg tray A to the guide hole plate, so that the embryonated eggs of different heights can be equally limited in the guide hole plate; the embryonated eggs of different sizes and heights can be directly placed in the egg tray, and there is no need to classify the embryonated eggs entering the harvester in advance; there is no need to readjust the pressing force and egg lifting height of the embryonated eggs entering the harvester in advance because the embryonated eggs are of different heights; S4: the shelling unit 3 performs shelling on the top of the embryo egg that is higher than the guide hole plate 253; S5: After the shelling is completed, the egg lifting unit 2 falls back, and the embryo eggs that have completed the shelling action fall back into the egg tray, and then the egg tray is sent to the location of the detection unit 4 by the intermediate transmission component; the egg shells produced after the shelling are collected by the shell blowing component 26 and then discharged uniformly; S6: The detection unit 4 identifies the embryo eggs after shelling through the detection model created by deep learning, and sends the identification result to the harvesting unit 5. After the detection is completed, the intermediate transmission component sends the embryo egg tray to the location of the harvesting unit 5; S7: The harvesting unit 5 collects the allantoic fluid of the embryonated eggs that have passed the detection according to the recognition result, and refuses to collect the embryonated eggs that have failed the detection. After the collection is completed, the intermediate transmission component sends the embryonated egg tray to the position of the tray output unit 6; S8: The tray discharging unit 6 delivers the egg tray containing the collected embryo eggs horizontally.

[0049] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention.
