Description

Technical Field

[0001] The utility model belongs to the technical field of microbial cultivation and relates to an automatic inoculation loader. Background Art

[0002] Microbial sample cultivation is an important task in the fields of medical care, inspection and quarantine, disease control, and food safety. Currently, automatic inoculation loaders are commonly used in the inoculation, cultivation, separation, and detection and cultivation of microorganisms. For example, a Chinese patent discloses a microbial culture medium device [authorization announcement number is CN204474670U. The culture medium includes a box body, a box cover, a spring, a buckle, and a seat. The box body and the box cover are used in conjunction with each other and are hinged. A spring is installed at the hinge of the hinge connection. The spring keeps the box cover open when it is opened. The box body is also provided with a seat, and the box cover is also provided with a buckle. The buckle has a tooth. The buckle is engaged with the seat through the tooth, so that the box cover remains closed when it is closed.

[0003] The production of these culture media requires the box body and lid to be assembled together, resulting in a complex structural design, cumbersome assembly, and low assembly efficiency. Opening the lid requires a mechanical opening device, which is costly. During inoculation, the lid flips outward around the pivot axis, occupying a large space. If the lid and box body were separated, the contents could easily fall out during transport. Utility Model Content

[0004] The purpose of the utility model is to solve the above problems in the existing technology and to provide an automatic inoculation loader which is not easy for loaded articles to fall off and is easy to operate when opening the cover.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] An automatic inoculation loader includes a loading seat provided with a storage cavity and an upper cover separately provided from the loading seat, the loading seat having a first annular stop edge arranged around the storage cavity, the upper cover having a second annular stop edge, and when the upper cover is closed onto the loading seat, the second annular stop edge is located outside the first annular stop edge, the first annular stop edge has two oppositely arranged first openings, the second annular stop edge has two second openings respectively arranged opposite to the first openings, a spring connected to the upper cover is provided in the second opening, the loading seat is provided with a buckle that forms a snap-fitting action with the spring, and when the spring deforms inwardly, the spring can disengage from the snap-fitting of the buckle.

[0007] When the upper cover is positioned on the loading seat, the second annular retaining edge is positioned outside the first annular retaining edge. At this point, the first and second openings are positioned opposite each other, and the buckle and spring form a locking action to prevent the loaded items from falling. When the cover needs to be opened, the gripper of the robot simultaneously grasps the two opposing springs, causing them to elastically deform inward and disengage the buckle. The upper cover can then be further transferred by the robot.

[0008] The first opening provides clearance for the inward deformation of the spring. The first opening is connected to the second opening, forming a gas channel that provides air for the growth of microorganisms. Due to the presence of the spring and the buckle, the upper cover can be stably closed to the loading seat when the cover is not opened, and the loaded items are not likely to fall. When opening the cover, the grip of the robot's claws causes the two springs to elastically deform inward synchronously, disengaging the buckle from the engagement, and further transferring the upper cover through the robot. Compared to the traditional method of opening the cover first and then moving the cover, this method reduces the number of devices, saves costs, and eliminates the opening process, thereby improving opening efficiency.

[0009] In the above-mentioned automatic inoculation loader, a limiting step parallel to the upper surface of the loading seat is provided on the elastic piece, and when the upper cover is closed with the loading seat, the buckle is pressed on the limiting step.

[0010] When the buckle presses against the limiting step, the lower end of the second annular retaining edge abuts against the upper surface of the loader, and the first annular retaining edge radially limits the upper cover, ensuring the stability of the upper cover. Because the limiting step is parallel to the upper surface of the loading seat, the buckle can effectively disengage from the limiting step when the spring plate elastically deforms inward.

[0011] In the automatic inoculation loader, a notch is provided between the spring piece and the second annular retaining edge. Due to the presence of the notch, the second annular retaining edge will not block the spring piece from elastic deformation, thereby improving the elasticity of the spring piece.

[0012] In the above-mentioned automatic inoculation loader, a limiting groove is provided on the limiting step, and when the upper cover is closed with the loading seat, the buckle is pressed on the bottom surface of the limiting groove.

[0013] The cooperation between the limiting groove and the buckle can limit the circumferential position of the upper cover relative to the loading seat. The bottom surface of the limiting groove is parallel to the limiting step, which can facilitate the disengagement of the buckle.

[0014] In the above-mentioned automatic vaccination loader, a first guide slope is provided at the lower end of the spring piece, and the first guide slope is inclined from the inside to the outside and from the bottom to the top. The minimum distance between the two oppositely arranged first guide slopes on different spring pieces is smaller than the distance between the two oppositely arranged buckles, and the maximum distance between the two oppositely arranged first guide slopes is greater than the distance between the two oppositely arranged buckles.

[0015] The first guiding bevel is located just below the limiting groove. When the cover is closed, the first guiding bevel guides the buckle, making it convenient for the buckle to enter and press onto the bottom surface of the limiting groove.

[0016] In the above-mentioned automatic inoculation loader, a second guiding slope is provided on the buckle.

[0017] The inclination direction of the second guide bevel is the same as that of the first guide bevel. When closing the cover, the first guide bevel and the second guide bevel cooperate to guide the buckle, making it convenient for the buckle to enter and press onto the bottom surface of the limit groove.

[0018] In the above-mentioned automatic inoculation loader, the loading seat is provided with a mold opening located below the buckle. Since the buckle is L-shaped, in order to facilitate molding, the mold opening is provided at the lower part of the buckle.

[0019] In the above-mentioned automatic inoculation loader, a single or multiple clamping planes are provided on the outer side of the spring piece.

[0020] When opening the cover, the manipulator's grippers are located on the outside of the two gripping surfaces. When the grippers close, the two springs are elastically deformed inward. The gripping surfaces increase the contact surface between the grippers and the cover, making it difficult for the cover to escape from the grippers during transfer.

[0021] In the above automatic inoculation loader, a culture dish is provided in the storage cavity.

[0022] In the above automatic inoculation loader, a third annular retaining edge is provided on the outer periphery of the culture dish, and the height of the third annular retaining edge is higher than that of the first annular retaining edge.

[0023] The inner top surface of the upper cover is higher than the upper end surface of the third annular retaining edge, and a gap is formed between the two to facilitate airflow. The height of the third annular retaining edge is higher than that of the first annular retaining edge, making it easy to remove the culture dish from the loading seat.

[0024] In the above-mentioned automatic inoculation loader, the upper surface of the loader is provided with an adhesive area located on the side of the upper cover for attaching an information marking barcode.

[0025] Compared with the existing technology, this automatic inoculation loader has the following advantages:

[0026] The buckle and the spring form a locking action to prevent the loaded items from falling; when opening the cover, the two springs can be elastically deformed inward synchronously through the clamping of the robot claws, and simultaneously disengaged from the locking of the buckle, which is conducive to opening and closing the cover, and the transfer of the upper cover can be further realized through the robot. Compared with the traditional action of opening the cover first and then moving the cover, it reduces the production assembly parts and procedures, saves costs, and ensures stability in use.

DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figure 1-3 The automatic inoculation loader shown in the figure comprises a loading seat 1 with a storage cavity, a culture dish 3 arranged in the loading seat 1, and an upper cover 2 which is separated from the loading seat 1. The upper cover 2 can completely cover the culture dish 3. Figure 3 As shown, the loading base 1 has a first annular stop edge 11 arranged around the storage cavity, and the upper cover 2 is provided with a second annular stop edge 21. When the upper cover 2 is closed on the loading base 1, the second annular stop edge 21 is located outside the first annular stop edge 11. The outer periphery of the culture dish 3 is provided with a third annular stop edge 31. When the culture dish 3 is located in the storage cavity, the height of the third annular stop edge 31 is higher than the height of the first annular stop edge 11. When the box is closed, the inner top surface of the upper cover 2 is higher than the upper end surface of the third annular stop edge 31, and a gap is formed between the two to facilitate airflow.

[0035] like Figure 3As shown, the first annular retaining edge 11 has two first openings 12 arranged opposite to each other, and the second annular retaining edge 21 has two second openings arranged opposite to the first openings 12 respectively. A spring piece 22 connected to the upper cover 2 is provided in the second opening, and a notch 28 is provided between the spring piece 22 and the second annular retaining edge 21. A buckle 13 is provided on the loading seat 1 to form a snap connection with the spring piece 22. When the spring piece 22 is deformed inwardly, the spring piece 22 can be disengaged from the snap connection of the buckle 13.

[0036] When the upper cover 2 is placed on the loading base 1, the second annular retaining edge 21 is positioned around the outer periphery of the first annular retaining edge 11. At this point, the first opening 12 and the second opening are positioned one-on-one, and the latch 13 and the spring 22 engage to prevent the loaded items from falling. To open the cover, the gripper of the robot simultaneously grasps the two opposing springs 22, causing them to elastically deform inward and disengage from the latch 13. The upper cover 2 can then be further moved by the robot.

[0037] The first opening 12 provides clearance for the inward deformation of the spring 22. The first opening 12 is connected to the second opening to form an air passage, providing air for the growth of microorganisms. Due to the presence of the spring 22 and the buckle 13, the upper cover 2 can be stably closed to the loading seat 1 when the cover is not opened, ensuring that the loaded items are not easily dropped. When the cover is opened, the grip of the manipulator claws causes the two springs 22 to elastically deform inward synchronously, disengaging from the buckle 13, and further transferring the upper cover 2 through the manipulator. Compared with the traditional method of opening the cover first and then moving the cover, this method reduces the number of devices, saves costs, and eliminates the opening process, thereby improving the efficiency of opening the cover.

[0038] like Figure 4 and Figure 5 As shown, a limiting step 23 parallel to the upper surface of the loading seat 1 is provided on the elastic piece 22 , and the buckle 13 is pressed on the limiting step 23 when the upper cover 2 is closed with the loading seat 1 .

[0039] When the buckle 13 presses against the limiting step 23, the lower end of the second annular stop 21 abuts against the upper surface of the loader, and the first annular stop 11 radially limits the upper cover 2, ensuring the stability of the upper cover 2. Because the limiting step 23 is parallel to the upper surface of the loading base 1, the buckle 13 can effectively disengage from the limiting step 23 when the spring 22 elastically deforms inward.

[0040] like Figure 5 As shown, a limiting groove 24 is provided on the limiting step 23. When the upper cover 2 is closed over the loading seat 1, the buckle 13 is pressed against the bottom surface of the limiting groove 24. The cooperation between the limiting groove 24 and the buckle 13 can limit the circumferential position of the upper cover 2 relative to the loading seat 1. The bottom surface of the limiting groove 24 is parallel to the limiting step 23, which can facilitate the disengagement of the buckle 13.

[0041] In this embodiment, Figure 5 As shown, a first guide slope 25 is provided at the lower end of the spring piece 22. The first guide slope 25 slopes from the inside outward and from the bottom up. The minimum distance between two opposing first guide slopes 25 on different spring pieces 22 is less than the distance between two opposing buckles 13, and the maximum distance between two opposing first guide slopes 25 is greater than the distance between two opposing buckles 13. The first guide slope 25 is located directly below the retaining groove 24. When the lid is closed, the first guide slope 25 guides the buckle 13, facilitating the buckle 13 to enter and press against the bottom surface of the retaining groove 24.

[0042] like Figure 3 As shown, the buckle 13 is provided with a second guide slope 14. The inclination direction of the second guide slope 14 is the same as that of the first guide slope 25. When the lid is closed, the first guide slope 25 and the second guide slope 14 cooperate to guide the buckle 13, facilitating the buckle 13 to enter and press against the bottom surface of the limit groove 24. The loading base 1 is provided with a mold opening 15 below the buckle 13.

[0043] like Figure 4 and Figure 5 As shown, a clamping surface 26 is provided on the outer side of the spring piece 22. Two opposing clamping surfaces 26, located on different spring pieces 22, are arranged opposite each other. When opening the cover, the manipulator's gripping jaws are positioned on the outer sides of the two gripping surfaces 26. When the gripping jaws close, they elastically deform the two spring pieces 22 inward. The gripping surfaces 26 increase the contact surface between the gripping jaws and the upper cover 2, making it difficult for the upper cover 2 to escape from the gripping jaws during transfer.

[0044] like Figure 1 and Figure 3 As shown, the upper surface of the loader is provided with a pasting area 27 located on the side of the upper cover 2 for pasting information mark barcodes.

[0045] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope defined by the appended claims.
