Description

Technical Field

[0001] The utility model belongs to the technical field of animal frozen semen thawing, and particularly relates to an animal frozen semen thawing device. Background Art

[0002] Animal frozen semen includes pig semen, bovine semen, and chicken semen. In artificial insemination, there are two ways to store sperm: liquid storage and frozen storage. The limitation of liquid semen is its short shelf life of approximately seven days, while frozen sperm can last for decades. Cryopreservation is a fundamental and essential technology for both laboratory and field genetic optimization. The challenge with pig sperm cryopreservation is that, compared to other livestock sperm, such as bovine sperm and even human sperm, pig sperm has weaker freezing resistance. For example, the article "Bailey JL, Lessard C, Jacques J, Breque C, Dobrinski I, Zeng W, Galantino-Homer HL, 2008: Cryopreservation of boar semen and its future importance to the industry. Theriogenology 70, 1251-1259" emphasizes the importance of pig semen cryopreservation to the industry's future. Consequently, cryoprotectants and surgical protocols for pig sperm have been optimized year after year, leading the way in the United States, Europe, and Japan. To date, the commercial supply chain for cryopreserved boar semen consists of three work units in sequence: 1) at the boar stud, the semen is collected and cryopreserved; 2) logistics – the cold chain – transports the cryopreserved semen to the client’s breeding farm / factory; and 3) at the breeding farm / factory, the semen is thawed and the maternal insemination process is performed by trained breeding technicians.

[0003] The optimal thawing procedure is a two-step process, involving removal of the sample from liquid nitrogen, a shorter thawing period in a water bath at a high temperature, such as 50°C to 70°C, for 10-15 seconds, and then warming to 26°C or 37°C before artificial insemination for optimal sperm motility. Typically, animal sperm is thawed only at 37°C. Therefore, the 12-second step at 60°C is crucial for maintaining sperm motility. Under these conditions, the frozen semen is thawed in the straw, but the temperature does not exceed 26°C.

[0004] Currently, during the processing of porcine semen, suppliers of frozen boar sperm have no control over the subsequent thawing process. If the pig farm operates improperly, a large number of frozen sperm may not survive the thawing process. Furthermore, genetic screening requires rigorous data collection. Inadequately skilled labor not only damages samples but also compromises data reliability and the traceability of biological samples.

[0005] At the same time, pig semen freezing technology is essential for breeding high-quality pigs and ensuring biosafety and stability. However, due to the fragile freeze resistance of pig semen, the requirements for antifreeze agents and the freezing and thawing processes are more stringent. Therefore, it is necessary to develop a frozen semen thawing device. Utility Model Content

[0006] The purpose of the present utility model is to provide an animal frozen semen thawing device to solve the above technical problems. In the present technical solution, a picking mechanism is used to pick up and transfer the straw in the liquid nitrogen freezing tank, and the rapid thawing time in seconds is standardized. During the pushing process of the straw pushing mechanism, the inner surface of the guide hole contacts the outer surface of the straw, thereby completing the operation of wiping moisture from the surface of the straw. A first moving mechanism and a pushing needle are provided, so that the pushing needle can be moved by the first moving mechanism, thereby moving the pushing needle to the inside of the straw to extrude the animal frozen semen inside the straw. At the same time, the forward and reverse rotation of the pushing motor can be controlled to realize the reciprocating lifting and lowering of the pushing needle, thereby pushing out the animal frozen semen inside the straw. Thereby, the effect of squeezing out the animal frozen semen multiple times is achieved, so that the utilization rate of the animal frozen semen inside the straw is higher; this extrusion method can realize automated operation and standardized operation, avoid human errors or mistakes caused by manual operation that affect the survival rate of the animal frozen semen, and make up for the current labor shortage problem; at the same time, after cutting the A end and B end of the straw, the thawed animal frozen semen falls spontaneously under the action of gravity, but due to its certain viscosity, the thawed animal frozen semen cannot be completely transferred to the outside, so by knocking on the surface of the straw, the animal frozen semen inside the straw is more likely to fall off; or by setting an air supply mechanism at the B end, the thawed animal frozen semen inside the straw can be transferred to the outside by blowing air.

[0007] In the present technical solution, the straw is taken out of the liquid nitrogen in a standardized manner and transferred to a thawing tank for thawing, wherein the thawing temperature is, for example, 50 degrees Celsius and the thawing time is, for example, 12 seconds. After thawing, the thawed animal semen is quickly transferred to a dilution cylinder for dilution, which can effectively avoid damage to the thawed animal semen by the freezing liquid. This operation process can realize standardized operation in seconds for rapid thawing, which can achieve standardized process operation that is difficult to achieve through manual operation. At the same time, it can effectively avoid errors caused by human operation in the time control of the thawing process and the transfer of the thawed animal frozen semen, and realize a standardized operation process with a rapid thawing time in seconds.

A flipping motor is provided to flip the clamping mechanism so that when the clamping mechanism needs to assemble the thawed straw, the flipping motor drives the clamping mechanism to flip to a horizontal state, and cooperates with the straw pushing mechanism provided on one side of the clamping mechanism to push the thawed straw into the clamping hole.

[0052] The technical solution of the present utility model is described in detail below with reference to specific embodiments.

[0053] Reference Figures 1 to 20A frozen animal semen thawing device includes an animal frozen semen transfer mechanism 1, comprising a straw 10 for loading the frozen animal semen, a clamping mechanism 11 for clamping the straw 10, and a push transfer mechanism 12 vertically disposed above the straw 10. The push transfer mechanism 12 includes a first moving mechanism 121 and a push needle 122 connected to the first moving mechanism 121.

The first moving mechanism 121 includes a pushing motor 1211, a third slide rail 1212, a third slider 1213 movably connected to the third slide rail 1212, a third screw rod 1214 that is transmission-connected to the pushing motor 1211 and threadedly connected to the third slider 1213, the pushing needle 122 is fixedly connected to the third slider 1213 and arranged parallel to the third screw rod 1214, the pushing motor 1211 and the third slide rail 1212 are fixedly arranged on the first frame 13; the first moving mechanism 121 and the pushing needle 122 are arranged so that the pushing needle 122 can be moved by The first moving mechanism 121 is driven to move, so that the pushing needle 122 moves to the inside of the straw 10, and the animal frozen semen inside the straw 10 is squeezed out. At the same time, the forward and reverse rotation of the pushing motor 1211 can be controlled to realize the reciprocating lifting and lowering of the pushing needle 122, thereby achieving the effect of squeezing out the animal frozen semen multiple times, so that the utilization rate of the animal frozen semen inside the straw 10 is higher; this extrusion method can realize automated operation and standardized operation, avoid human errors or mistakes caused by manual operation that affect the survival rate of animal frozen semen, and can make up for the current labor shortage problem.

[0054] The outer diameter of the pushing needle 122 is smaller than the inner diameter of the straw 10. The pushing needle 122 can smoothly enter the interior of the straw 10 to squeeze out the frozen semen of the animal inside the straw 10, thereby avoiding errors caused by manual operation.

[0055] The clamping mechanism 11 includes a first carrier plate 111, a first motor 112 arranged on one side of the first carrier plate 111, a movable plate body 113 arranged on the other side of the first carrier plate 111 and movably connected to the movable end of the first motor 112, and a first guide column 114 fixedly arranged on the first carrier plate 111 and movably connected to the movable plate body 113. The first guide column 114 is provided with a clamping hole 1140 for cooperating with the movable plate body 113 to clamp the capillary tube 10. An arcuate groove surface 1130 is provided on one side of the movable plate body 113 to fit the outer surface of the capillary tube 10. The provision of the arcuate groove surface 1130 allows the movable block to fit a larger area of the capillary tube 10, making the state of clamping the capillary tube 10 more stable. The movable plate body 113 and the first guide column 114 are clearance-fitted; the movable plate body 113 and the movable end of the first motor 112 are threadedly connected. The first motor 112 is fixedly mounted on the first supporting plate 111 ; the movable plate 113 and the first guide column 114 are arranged in a group. In this embodiment, the number of movable plates 113 is 2, and the number of first guide columns 114 is 4, which are all symmetrically arranged. The first guide column 114 is arranged in two vertical groups to clamp the capillary 10 and keep the capillary 10 in a vertical state; the movable end of the first motor 112 is threadedly connected to the movable plate 113, and the forward and reverse rotation of the first motor 112 can be controlled, and under the guiding action of the first guide column 114, the movable plate 113 moves in the axial direction relative to the first motor 112. The movable plate 113 adjusts the size of the leakage area of the clamping hole 1140 during the movement. When the capillary 10 needs to be clamped, after the capillary 10 passes through the clamping hole 1140, the first motor 112 is controlled to rotate until the movable plate 113 contacts the surface of the capillary 10, forming a multiple fitting state in which the arc groove surface 1130 of the movable plate 113 fits the capillary 10 and the inner surface of one side of the clamping hole 1140 fits the capillary 10, thereby improving the fixing stability of the capillary 10.

[0056] A flip motor 15 is provided on one side of the clamping mechanism 11 to flip the entire mechanism. The first supporting plate 111 is fixedly connected to the movable end of the flip motor 15; the setting direction of the flip motor 15 is perpendicular to the plane projection direction of the first supporting plate 111. The first supporting plate 111 of the clamping mechanism 11 is hinged to the first frame 13, the flip motor 15 is fixedly connected to the first frame 13, and the movable end of the flip motor 15 is connected to the first supporting plate 111. The first frame 13 is provided with a connecting block 131, and the first supporting plate connection 111 is hinged to the connecting block 131 with a movable shaft 1311, and the movable shaft 1311 is fixedly connected to the movable end of the flip motor 15. A disk 1312 is provided on the side of the movable shaft 1311 away from the flip motor, and the disk 1312 is in contact with the surface of the connecting block 131. A flip motor 15 is provided to flip the clamping mechanism 11 so that when the clamping mechanism 11 needs to be equipped with the thawed straw 10, the flip motor 15 drives the clamping mechanism 11 to flip to a horizontal state, and cooperates with a straw pushing mechanism provided on one side of the clamping mechanism 11 to push the thawed straw 10 into the clamping hole 1140. After the clamping mechanism 11 clamps the straw 10 and shears the end B of the straw, the flip motor 15 can be controlled to drive the clamping mechanism 11 to flip to a vertical state, so as to facilitate the transfer of the frozen animal semen in the straw 10 into the dilution cylinder after shearing.

[0057] After the flipping motor 15 drives the clamping mechanism 11 to perform the flipping operation, the clamping mechanism forms a vertical state. At this time, the A end of the straw is not sheared. The push needle 122 only enters from the B end and pierces the A end of the straw vertically downward, so that the thawed animal semen inside is transferred to the outside.

[0058] Alternatively, the A and B ends of the straw can be cut, and the thawed animal semen will fall spontaneously under the action of gravity. However, due to its certain viscosity, the thawed animal semen cannot be completely transferred to the outside. Therefore, by knocking on the surface of the straw, the animal semen inside the straw can be made to fall more easily; or by setting an air supply mechanism at the B end, the thawed animal semen inside the straw can be transferred to the outside by blowing air.

[0059] The clamping mechanism 11, the pushing and transferring mechanism 12, and the flipping motor 15 are all arranged on the first frame 13, and the first frame 13 is movably connected to the second moving mechanism 14;

[0060] The second moving mechanism 14 includes a second motor 141, a first screw rod 142 drivingly connected to the second motor 141, a first slider 143 threadedly connected to the first screw rod 142 and fixedly disposed below the first frame 13, and a first slide rail 144 movably connected to the first slider 143. The second moving mechanism 14 is configured so that the first frame 13 can be driven to move by the rotation of the second motor 141, allowing the clamping mechanism 11 to be adjusted in position according to needs, such as the assembly position before clamping the straw 10, shearing the straw 10 after clamping the straw 10, and squeezing the frozen animal semen inside the straw 10 into the dilution cylinder after clamping the straw 10. This provides a high degree of automation and avoids errors caused by human intervention.

[0061] A shearing mechanism 2 is provided below the clamping mechanism 11, and the shearing mechanism 2 includes a turntable 21 and a third motor 22 that is transmission-connected to the turntable 21. The third motor 22 is transmission-connected to a third moving mechanism, and the third moving mechanism includes a second slider 231 fixedly connected to the third motor 22, a second slide rail 232 movably connected to the second slider 231, a second screw rod 233 threadedly connected to the second slider 231, and a fourth motor 234 transmission-connected to the second screw rod 233. The moving direction of the shearing mechanism is perpendicular to the moving direction of the first frame. The shearing mechanism 2 shears one or both ends of the straw 10 loaded with animal frozen semen, so that the pushing needle 122 is pushed into the interior of the straw 10 and the animal frozen semen loaded in the straw 10 is squeezed out. The third motor 22 drives the turntable to rotate to shear the straw 10, and the fourth motor 234 is provided to enable the shearing mechanism 2 to move. The moving path of the shearing mechanism 2 is perpendicular to the moving path of the first frame 13 and the moving path of the push needle 122. The shearing operation can be performed during the movement of the shearing mechanism 2. At the same time, the moving path has a large adjustable range and a high degree of automation, which is conducive to the transfer operation of animal frozen semen.

[0062] A capillary pushing mechanism 3 is provided on one side of the clamping mechanism 11 for pushing the capillary 10 to the clamping mechanism 11 for clamping;

[0063] The capillary pushing mechanism 3 includes a pushing portion 31, a guide groove 32 arranged on one side of the pushing portion 31, and a second guide column 33 arranged at the end of the guide groove 32 and used to wipe moisture off the surface of the capillary 10 during the pushing process; the second guide column 33 is arranged opposite to the clamping hole 1140.

[0064] A camera 30 for monitoring the process of assembling the capillary tubes is provided on one side of the capillary tube pushing mechanism 3. The camera 30 is used to check whether the capillary tubes have burst. Since some capillary tubes 10 may not be well packaged, liquid nitrogen may seep into the capillary tubes when they are stored in liquid nitrogen. When the capillary tubes 10 are taken out for thawing, the capillary tubes 10 may burst. Therefore, a camera 30 is provided on one side of the end of the second guide column 33; the capillary tubes 10 are checked for bursting during the transmission and assembly process of the capillary tube pushing mechanism 3, and the inspection is performed during the assembly process, so that the camera 30 can inspect the capillary tubes 10 from the B end to the A end during the passage of the capillary tubes 10.

Vertically, the side of the guide hole 331 facing away from the guide slot is higher than the guide slot 32. The guide hole 331 is arranged opposite the clamping hole 1140. The thawed straw 10 in the thawing tank is transferred to the guide groove 32 by a picking mechanism. The active end of the through-axis hybrid stepper motor pushes the straw end A, so that the straw end B is positioned and transferred to the clamping hole 1140 through the second guide post 33 until the straw end A passes through the second guide post 33. The second guide post 33 is arranged opposite the clamping hole 1140, so that the straw 10 can be accurately assembled into the clamping hole 1140, improving the stability of the operation and providing a good foundation for the subsequent shearing of the straw 10 and the transfer of frozen animal semen. The high degree of automation avoids the need for manual operation and experimental errors.
