Description

Technical Field

[0001] This application relates to the field of feeding in an egg embryo extraction device, and more particularly to an egg feeding mechanism for an egg embryo extraction device. Background Technology

[0002] Vaccine development often requires a large number of egg embryos. Egg embryos generally need to undergo a complicated cultivation process before they can be used in vaccine development experiments. After cultivation, an egg embryo extraction device is usually used to remove the egg embryos from the eggs.

[0003] Reference Figure 1 and Figure 2 The related technology relates to an egg embryo extraction device, including a worktable with a turntable horizontally mounted on it. The turntable rotates intermittently in the vertical direction. Multiple support components for placing and fixing eggs are evenly spaced along the sides of the turntable. Multiple workstations are arranged around the turntable on the worktable, and these workstations are sequentially designated as a feeding station, a hole-drilling station, an eggshell removal station, an egg embryo extraction station, and a residual eggshell removal station. Each workstation corresponds to one of the support components. In use, the operator takes an egg from the feeding station and places it on a support component there. The worktable then rotates, causing the egg to be transferred to the next workstation for further processing.

[0004] Regarding the aforementioned technologies, the inventors believe that the device operates continuously during operation, and manual feeding is required. The repeated feeding operation over a long period of time can easily cause muscle fatigue among the staff, which can lead to errors such as knocking or bumping the eggshell, damaging the egg embryo and affecting its activity. This, in turn, can adversely affect the accuracy of experimental results in vaccine development. Summary of the Invention

[0005] To improve the stability of the feeding operation, this application provides an egg feeding mechanism for an egg embryo extraction device.

[0006] The egg feeding mechanism for an egg embryo extraction device provided in this application adopts the following technical solution: An egg feeding mechanism for an egg embryo extraction device includes a feeding assembly and a picking assembly disposed at a feeding station. The picking assembly includes a body with a connecting plate rotatably mounted on it in a vertical direction. The connecting plate is also vertically mounted on the body. The body has a first driving component for rotating the connecting plate and a second driving component for lifting the connecting plate. Both ends of the connecting plate have picking components for picking up eggs from the feeding assembly and placing them on the station. The two picking components are symmetrically positioned along the rotation axis of the connecting plate. The picking components rotate with the connecting plate to a position directly above a supporting assembly at the feeding station. The feeding assembly includes a mounting plate that can be adjusted horizontally in multiple directions. An egg-holding frame is detachably mounted on the mounting plate. The egg-holding frame has a rectangular array of multiple egg-holding intervals. The eggs placed in the egg-holding frame are on the same horizontal plane as the eggs placed in the supporting assembly.

[0007] By adopting the above technical solution, when the egg embryo extraction device is running, the egg feeding mechanism cooperates in feeding. Before the feeding mechanism runs, the eggs are first placed in the egg holding compartment, and then the egg holding frame is installed on the mounting plate. At this time, a pneumatic clamp is positioned above the egg holding frame. Then, the second drive component drives the connecting plate to descend, and then the pneumatic clamp operates to clamp the egg. Then, the second drive component drives the connecting plate to rise, and the first drive component drives the connecting plate to rotate 180°. At this time, the positions of the two pneumatic clamps are exchanged, and the pneumatic clamp holding the egg is now located at the bearing at the feeding station. Above the egg-holding assembly, as the connecting plate rises and rotates, the mounting plate moves, causing another egg-holding compartment containing eggs to shift to the position where the previous egg was clamped. Then, the second drive unit drives the connecting plate downwards, and the pneumatic clamp holding the egg releases, allowing the egg to be placed into the supporting assembly at the loading station. Meanwhile, another pneumatic clamp, not holding an egg, holds the egg in the egg-holding compartment. This process is repeated, transferring the clamped eggs to the loading station. The turntable then rotates a short distance, positioning the next supporting assembly at the loading station. This setup, using an egg-loading mechanism instead of manual loading, avoids the fatigue of manually bumping the eggshells, thus maintaining the viability of the egg embryo and ensuring the accuracy of experimental results. Furthermore, the rotation of the connecting plate allows the two pneumatic clamps to alternately load at fixed points, resulting in faster loading speeds and improved overall efficiency of egg embryo extraction.

[0008] Optionally, the workbench is provided with a support plate at the location of the mounting plate. The support plate is provided with a third driving member for driving the mounting plate to move horizontally back and forth, and a fourth driving member for driving the mounting plate to move horizontally back and forth. The directions in which the third driving member and the fourth driving member drive the mounting plate to move are perpendicular to each other.

[0009] By adopting the above technical solution, when the mechanism is running, the mounting plate is driven to move horizontally by the third and fourth driving components, so that the egg-holding interval containing eggs is located below the pneumatic clamp that does not hold eggs. At this time, the pneumatic clamp holds the eggs in the egg-holding interval, and after the eggs are clamped and removed, the above operation is repeated, so that another egg-holding interval containing eggs moves to the position where the pneumatic clamp can hold the eggs. This setting allows the pneumatic clamp to clamp eggs at a fixed point for feeding. The pneumatic clamp has a short travel trajectory and the process of clamping and transferring eggs is short, which further improves the feeding speed. Moreover, the pneumatic clamp's running trajectory is simpler, the programming design of the mechanism control is easier, and the machine manufacturing design cost is saved.

[0010] Optionally, there are multiple material holding components and multiple material picking components.

[0011] By adopting the above technical solution, when all the eggs in one of the feeding components are removed, another feeding component takes eggs from another feeding component that already contains eggs. At this time, the prepared egg-holding basket is replaced in the previously used feeding component. Then, after all the eggs in the other feeding component are removed, feeding continues through the original feeding and receiving components. This setup, with multiple sets of feeding and receiving components used alternately, eliminates the need to stop the machine to replace the egg-holding baskets after they are used up, further improving the continuity of the overall feeding process and thus the overall operating efficiency of the device.

[0012] Optionally, the pickup component is a pneumatic clamp, which includes two symmetrical clamping plates. A first telescopic cylinder is provided with both ends of the connecting plate facing downwards. A mounting frame is fixedly provided on the cylinder body of the first telescopic cylinder. The clamping plates are rotatably mounted on the mounting frame. A transmission plate is provided on the piston rod of the first telescopic cylinder. Connecting blocks are rotatably provided on both ends of the transmission plate near the clamping plates. The connecting blocks are rotatably connected to the clamping plates, and the connection points between the connecting blocks and the clamping plates are located on the side of the clamping plates that are close to each other. The rotation axes of the clamping plates and the mounting frame, the clamping plates and the connecting blocks, and the connecting blocks and the transmission plate are all parallel to each other and perpendicular to the sliding direction of the piston rod of the first telescopic cylinder.

[0013] By adopting the above technical solution, when the pneumatic clamp picks up the egg, the piston rod of the first telescopic cylinder retracts, driving the transmission plate to move towards the first telescopic cylinder, which in turn drives the connecting block to move towards the first telescopic cylinder. This causes the ends of the two clamping plates that are close to each other and the ends that are close to the first telescopic cylinder to move towards the first telescopic cylinder, thus causing the two clamping plates to rotate closer to each other along the rotation axis between the clamping plates and the mounting bracket. Conversely, when the egg is placed down, the piston rod of the first telescopic cylinder extends, causing the two clamping plates to rotate away from each other. With this configuration, the rotation of the two clamping plates can be controlled by a single telescopic cylinder, making operation convenient and quick.

[0014] Optionally, the sidewalls of the clamping plates that are close to each other are provided with support members for supporting the eggs at the ends away from the first telescopic cylinder.

[0015] By adopting the above technical solution, when there are cracks on the surface of the egg, the egg is easily broken when the clamping plates rotate and move closer together to hold the egg, which will damage the egg embryo, waste experimental materials, and require shutdown for cleaning, which seriously affects the efficiency of the device. At this time, the egg is supported by the support components that move closer together, and the egg is supported and transported instead of clamped and transported, which reduces the lateral pressure on the egg and thus reduces the possibility of the egg breaking.

[0016] Optionally, the sidewalls of the clamps that are close to each other are provided with limiting members on the side away from the support member to limit the periphery of the egg.

[0017] By adopting the above technical solution, when the clamps rotate and move closer to each other towards the egg, the supporting component supports the egg, and the limiting component moves closer to each other and combines around the egg to limit the egg, reducing the possibility of the egg tipping over and falling during transportation, thereby further protecting the egg embryo.

[0018] Optionally, the support member is in the shape of an arc-shaped plate, and the limiting member is in the shape of an arc-shaped plate.

[0019] By adopting the above technical solution, when the supporting parts are close to each other to support the egg, and when the limiting parts are close to each other to support the egg, the arc-shaped supporting parts and the arc-shaped limiting parts make the egg more evenly stressed, further reducing the possibility of the egg breaking and making the egg less likely to fall.

[0020] Optionally, a second telescopic cylinder is horizontally arranged at both ends of the connecting plate. A mounting block is provided on the piston rod of the second telescopic cylinder, and a first rotating cylinder is provided on the mounting block. The output shaft of the first rotating cylinder is vertically downward, and the first telescopic cylinder is inclinedly connected to the output shaft of the first rotating cylinder through a bend plate.

[0021] By adopting the above technical solution, the pneumatic clamp needs to be calibrated and adjusted before the mechanism is used. This is achieved by adjusting the extension and retraction of the second telescopic cylinder, which moves the mounting block horizontally, thereby changing the distance between the pneumatic clamp and the rotation center of the connecting plate, and thus changing the rotation radius of the pneumatic clamp. During movement, the piston rods of the two second telescopic cylinders extend to the same length, ensuring a consistent rotation radius for the pneumatic clamp. Furthermore, the first rotary cylinder rotates the angle of the pneumatic clamp. This design makes the calibration and adjustment process of the pneumatic clamp convenient and quick, improving its adaptability in use.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. By setting up a feeding component and a feeding component, and having the feeding component rotate through two pneumatic clamps to complete alternating fixed-point feeding, it is beneficial to reduce eggshell collisions caused by manual feeding, and the fast fixed-point alternating feeding is beneficial to improve the efficiency of egg embryo extraction. 2. By setting up multiple sets of feeding components and multiple sets of dispensing components, when the eggs in one of the feeding components are all removed, another feeding component and dispensing component are run to feed the eggs. At this time, the egg-holding basket in the feeding component that has removed the eggs is replaced, and the egg-holding basket that is full of eggs is put back in. 3. By setting up a support component and placing it at the end of the side wall of the clamping plates that is close to each other and away from the first telescopic cylinder, the pneumatic clamping is changed to support by the support component, which reduces the lateral pressure on the egg and helps to reduce the possibility of the egg breaking.

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] This application discloses an egg feeding mechanism for an egg embryo extraction device.

[0032] Example 1 Reference Figure 1 and Figure 2 The egg embryo extraction device's egg feeding mechanism includes two sets of feeding and unloading components located at the feeding stations. There are two feeding stations on one side of the worktable 1, arranged sequentially along the rotation direction of the turntable 2. The feeding and unloading components are respectively located at each feeding station, with each feeding component corresponding to one side of each unloading component. Feeding is performed through the cooperation of the two feeding and unloading components. When one feeding component runs out of eggs, the other feeding and unloading component is activated to feed more eggs, improving the device's operating efficiency and saving time spent changing eggs.

[0033] Reference Figure 1 and Figure 3 The material handling assembly includes a body 4, with a lifting seat 5 vertically slidably mounted on a vertical side wall at the top of the body 4. A first driving component 6 is mounted on the top of the body 4. In this embodiment, the first driving component 6 can be a telescopic cylinder. The cylinder body of the telescopic cylinder is fixedly mounted on the top of the body 4 and vertically downwards. The bottom end of the piston rod of the telescopic cylinder is fixedly connected to the lifting seat 5. When the mechanism is running, the lifting seat 5 is driven to rise by the first driving component 6, making operation convenient and quick.

[0034] A second driving component 7 is provided on the lifting base 5. In this embodiment, the second driving component 7 can be a rotary cylinder. The output shaft of the rotary cylinder is vertically downward and rotates in the vertical direction. The cylinder body of the rotary cylinder is fixedly mounted on the lifting base 5, and a connecting plate 8 is fixedly mounted at the bottom of the output shaft of the rotary cylinder. The connecting plate 8 is horizontally positioned, and the output shaft of the rotary cylinder is connected to the center of the connecting plate 8. The connecting plate 8 rotates via the second driving component 7 and is raised and lowered via the lifting base 5, making operation convenient and quick.

[0035] Reference Figure 3 and Figure 4A second telescopic cylinder 9 is horizontally arranged at both ends of the connecting plate 8. The two second telescopic cylinders 9 are arranged opposite to each other and are symmetrically arranged around the center of the connecting plate 8. A mounting block 10 is fixedly installed on the end of the piston rod of the second telescopic cylinder 9 away from its own cylinder body. A first rotating cylinder 11 is fixedly installed at the bottom of the mounting block 10. The output shaft of the first rotating cylinder 11 is vertically downward and rotates in the vertical direction. A bend plate 12 is fixedly installed at the end of the output shaft of the first rotating cylinder 11 away from its own cylinder body. A picking device for picking up eggs from the material holding assembly and placing them on the work station is inclined at the bottom of the bend plate 12. The picking device is a pneumatic clamp 13. In other embodiments, the picking device can also be a vacuum suction cup. The two pneumatic clamps 13 are located at the same horizontal height and are symmetrically distributed around the center of the connecting plate 8. When the pneumatic clamps 13 rotate with the connecting plate 8, there is a moment when they are exactly above the supporting assembly 3 at the loading station. Before the mechanism is operated, the distance between the two pneumatic clamps 13 is adjusted by the second telescopic cylinder 9, and the angle of the pneumatic clamps 13 is adjusted by the first rotating cylinder 11, so that the pneumatic clamps 13 are more convenient to use and have a wider range of adaptability.

[0036] During operation, the two pneumatic clamps 13 are first positioned at the support assembly 3 and the material holding assembly, respectively. Then, the second drive component 7 drives the connecting plate 8 to descend, and the pneumatic clamps 13 clamp the eggs. Next, the second drive component 7 drives the pneumatic clamps 13 to rise, while the first drive component 6 drives the connecting plate 8 to rotate 180°, causing the positions of the two pneumatic clamps 13 to exchange. Then, the second drive component 7 drives the pneumatic clamps 13 to descend, and the pneumatic clamp 13 holding the eggs releases, while the pneumatic clamp 13 not holding eggs tightens to hold the eggs in the material holding assembly. The alternating feeding by the two pneumatic clamps 13 is stable and fast.

[0037] The pneumatic clamp 13 includes two symmetrically arranged clamping plates 131. A first telescopic cylinder 14 is inclinedly arranged at the bottom of the angle plate 12. The first telescopic cylinder 14 forms an angle of 30° with the vertical direction. A mounting bracket 15 is fixedly arranged on the cylinder body of the first telescopic cylinder 14, and the mounting bracket 15 is sleeved on the bottom of the cylinder body of the first telescopic cylinder. The clamping plates 131 are symmetrically arranged at both ends of the mounting bracket 15 perpendicular to the telescopic direction of the piston rod of the first telescopic cylinder 14. The tops of the two clamping plates 131 are connected to the mounting bracket 15 on opposite sides, and the clamping plates 131 are rotatably connected to the mounting bracket 15 along the telescopic direction perpendicular to the piston rod of the first telescopic cylinder 14. A transmission plate 16 is fixedly installed at the bottom of the piston rod of the first telescopic cylinder 14. Connecting blocks 17 are rotatably installed at both ends of the transmission plate 16 near the clamping plate 131. Each connecting block 17 is rotatably connected to a clamping plate 131 it is close to, with the connection point between the connecting block 17 and the clamping plate 131 located at the top of the side of the clamping plates 131 that are close to each other. The rotation axes of the clamping plate 131 and the mounting bracket 15, the clamping plate 131 and the connecting block 17, and the connecting block 17 and the transmission plate 16 are all parallel to each other and perpendicular to the sliding direction of the piston rod of the first telescopic cylinder 14. When the pneumatic clamp 13 clamps, the piston rod of the first telescopic cylinder 14 retracts, causing the connecting plate 8 to move towards the first telescopic cylinder 14, thereby causing the clamping plates 131 to rotate towards each other to complete the clamping. When the pneumatic clamp 13 releases, the piston rod of the first telescopic cylinder 14 extends, causing the connecting plate 8 to move away from the first telescopic cylinder 14, thereby causing the clamping plates 131 to rotate towards each other to complete the release.

[0038] Reference Figure 2 and Figure 5 The material holding assembly includes a mounting plate 18 with multi-directional horizontal movement adjustment. A rectangular support plate 19 is horizontally fixed on the worktable 1, located below the mounting plate 18. A third driving member 20 for driving the mounting plate 18 to move horizontally reciprocally is fixedly mounted on the top side wall of the support plate 19. In this embodiment, the third driving member 20 can be an electric slide table, and the slider of the electric slide table of the third driving member 20 slides along the length direction of the support plate 19. A fourth driving member 21 for driving the mounting plate 18 to move horizontally reciprocally is fixedly mounted on the slider of the third driving member 20. In this embodiment, the fourth driving member 21 can be an electric slide table, and the slider of the electric slide table of the fourth driving member 21 slides along the width direction of the support plate 19. The mounting plate 18 is fixedly mounted on the slider of the fourth driving member 21. By moving the sliders of the third driving member 20 and the fourth driving member 21 in mutually perpendicular directions, the mounting plate 18 has the ability to move along the horizontal XY axis.

[0039] An egg-holding frame 22 is detachably mounted on the top side wall of the mounting plate 18. Four guide rods 23 are vertically fixed on the top side wall of the mounting plate 18, evenly distributed on the mounting plate 18. The egg-holding frame 22 has four holes corresponding to the guide rods 23. The egg-holding frame 22 is fitted onto the guide rods 23 through these holes and placed onto the mounting plate 18. The egg-holding frame 22 has 36 egg-holding intervals 24 arranged in a 6x6 rectangular array. The eggs placed in the egg-holding frame 22 are on the same horizontal plane as the eggs placed in the support assembly 3. Installing the egg-holding frame 22 via the guide rods 23 is convenient and quick; and the fact that the eggs placed in the egg-holding frame 22 are on the same horizontal plane as the eggs placed in the support assembly 3 makes the pneumatic clamp 13 more stable in holding and placing the eggs.

[0040] When the mechanism is running, whenever an egg is picked out, the third drive component 20 drives the fourth drive component 21 to move the mounting plate 18 a distance of one egg-holding interval 24. After all the eggs in a row have been picked out, the fourth drive component 21 drives the mounting plate 18 to move a distance of one egg-holding interval 24. Then, after an egg is picked out, the third drive component 20 drives the fourth drive component 21 to move the mounting plate 18 in the opposite direction a distance of one egg-holding interval 24.

[0041] The implementation principle of Example 1 is as follows: When the egg embryo extraction device is running, the egg feeding mechanism is activated to feed the eggs. Before the feeding mechanism is activated, the eggs are placed in the egg holding interval 24, and then the egg holding frame 22 is installed on the mounting plate 18. Then, the distance between the two pneumatic clamps 13 is adjusted by the second telescopic cylinder 9, and the angle of the pneumatic clamps 13 is adjusted by the first rotating cylinder 11. One pneumatic clamp 13 is adjusted to be above the egg holding frame 22, and the other pneumatic clamp 13 is positioned above the support component 3 at the feeding station. Then, the mechanism is activated. At this time, the second driving component 7 drives the pneumatic clamp 13 to descend, and then the pneumatic clamp 13 clamps the eggs. Then, the second driving component 7 drives the pneumatic clamp 13 to rise, and the first driving component 6 drives the connecting plate 8 to rotate 180°. At this time, the two pneumatic clamps 13 are in a position to move. The positions of 3 are exchanged; and when the connecting plate 8 rises and rotates, the third drive member 20 and the fourth drive member 21 drive the mounting plate 18 to move so that the other egg-holding interval 24 containing eggs is moved to the position where the previous egg was clamped; then the second drive member 7 drives the pneumatic clamp 13 to descend, and the pneumatic clamp 13 holding the egg releases so that the egg is placed in the support component 3 at the loading station, and the other pneumatic clamp 13 that does not hold an egg holds the egg in the egg-holding interval 24; then the above operation is repeated so that the clamped egg is transferred to the loading station, and the turntable 2 rotates a distance so that the next idle support component 3 is located at the loading station; and after the eggs in one of the holding components are used up, the other holding component and the loading component are operated to load.

[0042] Example 2 Reference Figure 3 and Figure 6 The difference between this embodiment and Embodiment 1 is that each end of the sidewalls of the clamping plates 131 that are close to each other is provided with a support member 25 for supporting the egg. The support members 25 are symmetrically arranged and are arc-shaped plates. The two support members 25 are located on the same horizontal plane and their arc centers are close to each other. On the sidewalls of the clamping plates 131 that are close to each other, above the support members 25, there are spaced-apart limiting members 26 for limiting the periphery of the egg. The limiting members 26 are arc-shaped plates, located on the same horizontal plane and their arc centers are close to each other. By changing the clamping of the pneumatic clamp 13 to the support of the support members 25, the force on the egg is reduced, lowering the possibility of breakage of cracked eggs; and the limiting members 26 maintain the stability of the egg during transfer.

[0043] The implementation principle of Example 2 is as follows: the pneumatic clamp 13 is changed from the clamping of the support member 25 to the support. When transferring the egg with cracks, the clamp plate 131 moves closer and rotates, and the support member 25 supports the egg from the side and below, and then the egg is transferred; at this time, the limiting members 26 move closer to each other to limit the egg from the side and above.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
