Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a waste cap collection device for a microbial sample processing system. Background Technology

[0002] To facilitate opening the dish caps before inoculation and prevent them from detaching from the loading seat after inoculation, the applicant has invented a microbial sample processing system. This system includes a workbench, a pushing device mounted on the workbench, a rotating loading turntable and a flow turntable on the workbench. The loading turntable has a dish cap loading position and a loader loading position. The dish cap loading position is for placing new dish caps, and the loader loading position is for placing loaders. The flow turntable has multiple spaced loader receiving positions and dish cap receiving positions. The pushing device is used to place new dish caps located at the dish cap loading position. The device pushes the old lid to the loader receiving position and also pushes the loader located at the loader receiving position to the loader receiving position. The worktable is also equipped with an opening lid module, a marking module and a closing lid module arranged in sequence along the rotation direction of the flow turntable. The opening lid module is used to remove the old lid of the loader located at the loader receiving position. The old lid is designed separately from the loader, that is, the old lid is simply placed on the loader and is not connected to the loader in any way. The closing lid module is used to install the new lid onto the loader. The new lid is locked into the loader and will not fall off the loader.

[0003] As the microbial sample processing system operates, the cap-opening module continuously opens the old plate caps. If the old plate caps are placed directly on the workbench, it will not only take up a lot of space, but also affect the operation of other modules.

[0004] Therefore, it is necessary to collect the old dish lids in a centralized manner. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a waste cap collection device for a microbial sample processing system that can centrally collect used dish caps.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A waste plate collection device for a microbial sample processing system includes a collection basket with a horizontal inlet on its lower side. The collection basket contains a vertically extending collection chamber, and the horizontal inlet communicates with the collection chamber. Below the horizontal inlet is a top plate for pushing old plate caps entering through the horizontal inlet upwards. The top plate is driven by a power structure. The collection basket has a receiving structure located above the horizontal inlet. The receiving structure has a receiving state and a yielding state. When the top plate pushes the old plate cap upwards, the receiving structure is in the yielding state. After the old plate cap passes the receiving structure, the receiving structure can return to the receiving state under its own gravity. The receiving structure in the receiving state can support the old plate cap.

[0008] After the lid is opened, the old lid is sent into the collection basket through the horizontal inlet by the lid opening module. Then the top plate rises, causing the old lid to move upward. During this process, the old lid gradually presses upward against the receiving structure, causing it to move to the yielding state. After the old lid passes the receiving structure, the receiving structure can return to the receiving state under its own gravity. Then the top plate descends, the old lid is supported on the receiving structure, and the top plate returns to its initial position.

[0009] When there is already an old lid on top of an old lid, the upward movement of the old lid under the action of the top plate will cause all the old lids located above the receiving structure to move upward together.

[0010] In the waste cap collection device of the aforementioned microbial sample processing system, the receiving structure includes a first block and a second block disposed opposite each other on the collection basket. The first block and the second block are set at the same height. A first limiting block is provided above the first block. Under the action of gravity, the first block abutting against the first limiting block is in a receiving state. A second limiting block is provided above the second block. Under the action of gravity, the second block abutting against the second limiting block is in a receiving state. The distance between the first block and the second block on the receiving turntable is less than the diameter of the old plate cap. The first block swinging upward is in a yielding state, and the second block swinging upward is in a yielding state. The distance between the first block and the second block in the yielding state is greater than the diameter of the old plate cap.

[0011] The top plate can be round, square, or other shapes. The top surface area of ​​the top plate should not be less than 1 / 3 of the end surface area of ​​the old lid, which is conducive to stably lifting the old lid upward. The width of the top plate should be less than the distance between the first and second blocks when it is in the receiving state, so as to facilitate the up and down movement of the top plate.

[0012] In the receiving state, the upper part of the first stop block away from the second stop block abuts against the first limiting block, and the upper part of the second stop block away from the first stop block abuts against the second limiting block. The old lid, fed in through the transverse inlet, is centered between and below the first and second stops. The top plate pushes the old lid upwards, during which the old lid presses against the first and second stops, causing them to swing upwards respectively. The old lid then passes over the first and second stops, and the first and second stops, under their own gravity, swing downwards to return to the receiving state. The top plate then descends, and the old lid is supported by the first and second stops. This repetitive motion can lift the old lids one by one and limit them with the first and second stops.

[0013] In the waste cap collection device of the above-mentioned microbial sample processing system, there are two first blocks with their rotation center lines coaxial, and two second blocks with their rotation center lines coaxial. The distance between the two first blocks is less than the diameter of the old plate cap, and the distance between the two second blocks is less than the diameter of the old plate cap.

[0014] The old dish lid, fed in through the horizontal inlet, is centered between the two first blocks and the two second blocks and is lower than the first and second blocks. The old dish lid is supported by the four blocks, which improves stability and support effect.

[0015] In the waste cap collection device of the aforementioned microbial sample processing system, the collection basket includes a base plate, a first side plate and a second side plate disposed opposite each other on the base plate, the lower surface of the transverse inlet being the upper surface of the base plate, the collection chamber being located between the first side plate and the second side plate, a first stop block and a first limiting block being disposed on the first side plate, and a second stop block and a second limiting block being disposed on the second side plate, and the base plate having a clearance opening for the top plate to pass through. The first stop block and the first limiting block are disposed on the side of the first side plate, and the second stop block and the second limiting block are disposed on the side of the second side plate, and the opening size of the clearance opening is smaller than the outer diameter of the used plate cap.

[0016] In the waste cap collection device of the above-mentioned microbial sample processing system, the minimum distance between the first side plate and the second side plate is less than the outer diameter of the old plate cap. The side of the first side plate facing the second side plate has a first concave surface that matches the outer ring surface of the old plate cap. The side of the second side plate facing the first side plate has a second concave surface that matches the outer ring surface of the old plate cap. The first concave surface and the second concave surface constitute the inner ring surface of the collection cavity.

[0017] By using the first concave surface and the second concave surface to limit the old dish lid, the old dish lid can be prevented from falling off from the space between the first side plate and the second side plate.

[0018] In the waste cap collection device of the above-mentioned microbial sample processing system, there are two first side plates arranged on the same plane, and two second side plates arranged on the same plane. Each first side plate is provided with a first stop block and a first limiting block, and each second side plate is provided with a second stop block and a second limiting block. There are two top plates.

[0019] One first side plate and its opposite second side plate form a collection basket, and the other first side plate and its opposite second side plate form another collection basket. Both collection baskets can collect old dish lids. There are two clearance openings on the bottom plate, which correspond one-to-one with the two top plates. Old dish lids entering the upper collection basket through the horizontal inlet can be pushed to the lower collection basket by old dish lids entering later, and can be lifted upward by the top plates.

[0020] In the waste cap collection device of the above-mentioned microbial sample processing system, an installation plate is provided below the base plate, a support plate is provided on the installation plate, the base plate is fixed on the support plate, and the power structure is set on the installation plate.

[0021] In the waste cap collection device of the above-mentioned microbial sample processing system, the power structure includes a mounting base on the mounting plate, a linear drive unit vertically mounted on the mounting base, and a connecting rod driven by the linear drive unit. The end of the connecting rod away from the linear drive unit has an upwardly extending connecting section, and the top plate is located at the upper end of the connecting section.

[0022] When the linear drive unit is working, it drives the connecting rod to move up and down, ultimately realizing the up and down movement of the top plate.

[0023] Compared with existing technologies, the waste cap collection device of this microbial sample processing system has the following advantages: This waste cap collection device is installed on the workbench of the microbial sample processing system and collects old plate caps from bottom to top. It occupies little horizontal space and will not affect other modules of the microbial sample processing system, thus improving the stability of system operation. The overall structure is reasonably designed, and the first / second stop can automatically reset to the receiving state under the action of gravity. The structure is simple and more stable and reliable. Attached Figure Description

Detailed Implementation

[0030] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0031] like Figure 1-3 The waste cap collection device of the microbial sample processing system shown is set on the workbench of the microbial sample processing system and includes, from bottom to top, an installation plate 12, a support plate 13 on the installation plate 12, and a collection basket 2 on the support plate 13.

[0032] The collection basket 2 has a vertically extending collection cavity. The lower side of the collection basket 2 has a horizontal inlet 1 that communicates with the collection cavity. Below the collection cavity is a top plate 3 for pushing the old dish lid a that enters through the horizontal inlet 1 upward. The top plate 3 is driven by a power structure, which is mounted on the mounting plate 12. The collection basket 2 has a receiving structure located above the horizontal inlet 1. The receiving structure has a receiving state and a yielding state. When the top plate 3 pushes the old dish lid a upward, the receiving structure is in the yielding state. When the old dish lid a passes the receiving structure, the receiving structure can return to the receiving state under its own gravity. The receiving structure in the receiving state can support the old dish lid a.

[0033] After being opened, the old lid a is fed into the collection basket 2 through the horizontal inlet 1 by the lid-opening module. Then, the top plate 3 rises, causing the old lid a to move upwards. During this process, the old lid a gradually presses against the receiving structure, moving it to a yielding state. Once the old lid a has passed the receiving structure, the receiving structure returns to its receiving state under its own gravity. Then, the top plate 3 descends, supporting the old lid a on the receiving structure, and the top plate 3 returns to its initial position. When there is already an old lid a on top of another old lid a, the upward movement of the old lid a under the action of the top plate 3 will cause all the old lids a located above the receiving structure to move upwards together.

[0034] like Figure 5As shown, the opening module includes a horizontally extending linear module 22, a second lead screw motor 23 mounted on and driven by the linear module 22, and a crossbar 24 mounted on the second lead screw motor 23. A suction cup 25 connected to a negative pressure source is provided on the lower side of the end of the crossbar 24.

[0035] The linear module 22 can drive the second lead screw motor 23 to move linearly. The second lead screw motor 23 can drive the crossbar 24 and the suction cup 25 to move up and down, thereby realizing the lateral and up and down movement of the old dish lid a held by the suction cup 25, so as to open the lid first and then send the old dish lid a into the lateral inlet 1.

[0036] like Figure 1-3 As shown, the collection basket 2 includes a base plate 8, a first side plate 9 and a second side plate 10 disposed opposite to each other on the base plate 8. The base plate 8 is fixed on the support plate 13. The lower surface of the transverse inlet 1 is the upper surface of the base plate 8. The collection chamber is located between the first side plate 9 and the second side plate 10. The base plate 8 is provided with a clearance opening 11 for the top plate 3 to pass through. The opening size of the clearance opening 11 is smaller than the outer diameter of the old dish lid a.

[0037] In this embodiment, the minimum distance between the first side plate 9 and the second side plate 10 is less than the outer diameter of the old dish lid a. The side of the first side plate 9 facing the second side plate 10 has a first concave surface that matches the outer circumferential surface of the old dish lid a. The side of the second side plate 10 facing the first side plate 9 has a second concave surface that matches the outer circumferential surface of the old dish lid a. The first and second concave surfaces form the inner circumferential surface of the collection cavity. By limiting the old dish lid a with the first and second concave surfaces, the old dish lid a can be prevented from falling out of the space between the first side plate 9 and the second side plate 10.

[0038] like Figure 1-3 As shown, there are two first side plates 9, which are coplanar, and two second side plates 10, which are coplanar. The upper ends of the two first side plates 9 and the two second side plates 10 are fixed together by a connecting frame 21. Each first side plate 9 is provided with a first stop block 4 and a first limiting block 6, and each second side plate 10 is provided with a second stop block 5 and a second limiting block 7. The top plate 3 is provided with two.

[0039] One first side plate 9 and its opposite second side plate 10 form a collection basket 2, and the other first side plate 9 and its opposite second side plate 10 form another collection basket 2. Both collection baskets 2 can collect old dish lids a. Two clearance openings 11 are provided on the bottom plate 8 and are respectively set one-to-one with the two top plates 3. Old dish lids a entering the upper collection basket 2 through the transverse inlet 1 can be pushed to the lower collection basket 2 by old dish lids a entering later, and can be pushed upward by the top plates 3 respectively.

[0040] like Figure 1-3As shown, the receiving structure includes a first stop 4 and a second stop 5 disposed opposite to each other on the collection basket 2. The first stop 4 and a first limiting block 6 are disposed on the first side plate 9, and the second stop 5 and the second limiting block 7 are disposed on the second side plate 10. The first stop 4 and the first limiting block 6 are disposed on the side of the first side plate 9, and the second stop 5 and the second limiting block 7 are disposed on the side of the second side plate 10. The first stop 4 and the second stop 5 are disposed at the same height. The first limiting block 6 is disposed above the first stop 4, and under the action of gravity, it abuts against... The first stop 4, which rests against the first limiting block 6, is in a receiving state. A second limiting block 7 is provided above the second stop 5. Under the action of gravity, the second stop 5, which rests against the second limiting block 7, is in a receiving state. The distance between the first stop 4 and the second stop 5 on the receiving turntable is less than the diameter of the old lid a. The first stop 4, which is swung upward, is in a yielding state. The second stop 5, which is swung upward, is in a yielding state. The distance between the first stop 4 and the second stop 5, which are in the yielding state, is greater than the diameter of the old lid a.

[0041] In this embodiment, the top plate 3 is circular, the top surface area of ​​the top plate 3 is not less than 1 / 3 of the end surface area of ​​the old lid a, and the diameter of the top plate 3 is less than the distance between the first stop 4 and the second stop 5 when it is in the receiving state, so as to facilitate the up and down movement of the top plate 3.

[0042] When in the receiving state, the upper part of the first stop 4, away from the second stop 5, abuts against the first limiting block 6, and the upper part of the second stop 5, away from the first stop 4, abuts against the second limiting block 7. The old dish lid a, fed in through the transverse inlet 1, is centered between and below the first stop 4 and the second stop 5. The top plate 3 pushes the old dish lid a upwards. During this process, the old dish lid a presses against the first stop 4 and the second stop 5, causing them to swing upwards respectively. Then, the old dish lid a passes over the first stop 4 and the second stop 5, and the first stop 4 and the second stop 5 swing downwards to return to the receiving state under their own gravity. Then, the top plate 3 descends, and the old dish lid a is supported by the first stop 4 and the second stop 5. This reciprocating action can lift the old dish lids a one by one and limit them with the first stop 4 and the second stop 5.

[0043] like Figure 1 and Figure 3 As shown, there are two first stops 4, both coaxial with their rotation center lines, and two second stops 5, also coaxial with their rotation center lines. The distance between the two first stops 4 is less than the diameter of the old lid a, and the distance between the two second stops 5 is also less than the diameter of the old lid a. The old lid a, fed in through the transverse inlet 1, is centered between the two first stops 4 and the two second stops 5, and is lower than the first stops 4 and the second stops 5. The four stops support the old lid a, improving its stability and support effect.

[0044] like Figure 1 , Figure 2 and Figure 4 As shown, the power structure includes a mounting base 14 on the mounting plate 12, a linear drive unit vertically mounted on the mounting base 14, and a connecting rod 17 driven by the linear drive unit. In this embodiment, the linear drive unit is a lead screw motor 15. The end of the connecting rod 17 away from the lead screw motor 15 has an upwardly extending connecting section 18, and the top plate 3 is located at the upper end of the connecting section 18. When the lead screw motor 15 is working, it drives the spline shaft 16 to move up and down, thereby driving the connecting rod 17 to move up and down, ultimately realizing the up and down movement of the top plate 3.

[0045] To improve stability, such as Figure 4 As shown, a vertically extending guide rail 19 is provided on the mounting base 14, and a slider 20 is slidably provided on the guide rail 19. The connecting rod 17 is fixed on the slider 20. When the second lead screw motor 23 works, it can drive the connecting rod 17 to move up and down. During the movement, it is guided by the slider 20 and the guide rail 19.

[0046] In other embodiments, the linear drive element may be a cylinder.

[0047] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model.
