Description

Technical Field

[0001] This utility model relates to the field of petri dish technology, and in particular to a petri dish feeding device. Background Technology

[0002] In biological experiments, microbial culture, and medical testing, petri dishes are the core equipment for holding culture media and culturing samples. A petri dish loading device is a means of collecting and storing petri dishes, providing a fundamental guarantee for subsequent centralized storage, transportation, or further processing. In existing technologies, petri dish loading devices typically include a frame and a pushing mechanism. The frame has a receiving cavity for collecting petri dishes, and the pushing mechanism pushes the petri dishes to be collected one by one into the receiving cavity on the frame. When the receiving cavity is full, the operator must stop the operation of the loading device, remove the full petri dishes, and transfer them, then restart the loading device to continue collecting petri dishes. This stop-and-remove method interrupts the loading and collection process, thus reducing the efficiency of petri dish loading and collection. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a petri dish feeding device, which is beneficial to improving the feeding and collection efficiency of petri dishes.

[0004] The culture dish feeding device according to an embodiment of the present invention includes a frame with a lifting station and a pushing station; a turntable disposed above the lifting station, the turntable having multiple receiving cavities distributed circumferentially around the axis of the turntable, the receiving cavities being used to collect culture dishes, the turntable being rotatably connected to the frame so that the multiple receiving cavities can sequentially rotate to the top of the lifting station; a pushing mechanism disposed on the frame, the pushing mechanism being used to push the culture dishes at the pushing station to the lifting station; and a lifting mechanism disposed on the frame, the lifting mechanism being used to push the culture dishes at the lifting station upward into the receiving cavities.

[0005] It has at least the following beneficial effects: When it is necessary to collect culture dishes, the turntable rotates, causing one of the multiple circumferentially distributed receiving cavities on the turntable to be positioned above the lifting station. Then, the pushing mechanism is activated, pushing the culture dishes placed at the pushing station to be collected to the lifting station. Next, the lifting mechanism is activated, pushing the culture dishes at the lifting station upwards, allowing them to enter the receiving cavity currently above the lifting station. The pushing and lifting mechanisms repeat the above actions, with the pushing mechanism continuously pushing the culture dishes at the pushing station to the lifting station, and the lifting mechanism simultaneously pushing the culture dishes at the lifting station upwards into the receiving cavity, allowing the culture dishes to be stacked one by one within the receiving cavity. When the receiving cavity above the lifting station is full, the turntable continues to rotate, moving the next empty receiving cavity above the lifting station, and the pushing and lifting process is repeated to achieve continuous culture dish collection. This petri dish loading device, with a turntable featuring multiple receiving cavities above the lifting station, along with a pushing mechanism and a lifting mechanism, allows petri dishes to be stacked and collected one by one within the receiving cavities. Once a cavity is full, the turntable rotates to move the empty cavity above the lifting station to continue loading and collecting petri dishes. Furthermore, during loading and collecting in one cavity, workers can remove and transfer the collected petri dishes without stopping the machine, effectively preventing interruptions in the loading and collecting process and thus improving the efficiency of petri dish loading and collecting.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0019] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0020] refer to Figures 1 to 3 This utility model discloses a petri dish feeding device, including a frame 500, a turntable 100, a pushing mechanism 200 and a lifting mechanism 300. The frame 500 is provided with a lifting station 530 and a pushing station 540; a turntable 100 is located above the lifting station 530, and the turntable 100 is provided with multiple receiving cavities 121, which are circumferentially distributed around the axis of the turntable 100. The receiving cavities 121 are used to collect the culture dishes 10. The turntable 100 is rotatably connected to the frame 500 so that the multiple receiving cavities 121 can rotate sequentially to the top of the lifting station 530; a pushing mechanism 200 is located on the frame 500 and is used to push the culture dishes 10 at the pushing station 540 to the lifting station 530; a lifting mechanism 300 is located on the frame 500 and is used to push the culture dishes 10 at the lifting station 530 upward into the receiving cavity 121.

[0021] Understandably, when it is necessary to collect the culture dish 10, the turntable 100 rotates, causing one of the multiple circumferentially distributed receiving cavities 121 on the turntable 100 to rotate above the lifting station 530; then the pushing mechanism 200 is activated, pushing the culture dish 10 to be collected placed at the pushing station 540 to the lifting station 530; next, the lifting mechanism 300 is activated, pushing the culture dish 10 at the lifting station 530 upwards, so that the culture dish 10 enters the receiving cavity 121 that is now above the lifting station 530; the pushing mechanism 200 and the lifting mechanism 300 repeat the process. In the aforementioned actions, the pushing mechanism 200 continuously pushes the culture dish 10 at the pushing station 540 to the lifting station 530, and the lifting mechanism 300 simultaneously pushes the culture dish 10 at the lifting station 530 upward into the receiving cavity 121, so that the culture dishes 10 are stacked one by one in the receiving cavity 121; when the culture dishes 10 stacked in the receiving cavity 121 above the lifting station 530 reach the full state, the turntable 100 continues to rotate, and rotates the next empty receiving cavity 121 above the lifting station 530, and repeats the steps of pushing and lifting to realize the stacking and collection of culture dishes 10, so as to realize the continuous feeding and collection of culture dishes 10. This petri dish loading device, by using a turntable 100 with multiple receiving cavities 121 above the lifting station 530, and in conjunction with a pushing mechanism 200 and a lifting mechanism 300, not only allows petri dishes 10 to be stacked and collected one by one in the receiving cavities 121 to complete the loading and collection of petri dishes 10, but also allows the empty receiving cavity 121 to be directly switched to the top of the lifting station 530 to continue loading and collecting petri dishes 10 after one receiving cavity 121 is full, via the rotation of the turntable 100. Furthermore, during the loading and collection process in one receiving cavity 121, the operator can remove and transfer the completed petri dish 10 from the receiving cavity 121 without stopping the machine, effectively avoiding interruptions in the loading and collection process of petri dishes 10, thus improving the loading and collection efficiency of petri dishes 10.

[0022] It should be explained that the culture dish feeding device of this utility model embodiment is used in conjunction with a handling robot. The handling robot can transport the culture dish 10 in the temporary storage area to the pushing station 540, so that the culture dish feeding device can collect the culture dish 10 in the temporary storage area.

[0023] refer to Figures 2 to 4The petri dish feeding device also includes multiple one-way passage components 400. The turntable 100 has multiple passage holes 110, each corresponding to a multiple receiving cavity 121 and communicating with it. The passage holes 110 allow the petri dish 10 to pass through and move into the receiving cavity 121. The multiple one-way passage components 400 are all located on the turntable 100 and correspond to the multiple passage holes 110. The one-way passage components 400 ensure that the petri dish 10 can only pass upwards through the passage holes 110. When the turntable 100 rotates, the corresponding passage holes 110 and receiving cavities 121 can sequentially rotate to the top of the lifting position 530.

[0024] Understandably, after the pushing mechanism 200 pushes the culture dish 10 to the lifting position 530, the lifting mechanism 300 pushes the culture dish 10 upward at the lifting position 530. Under the action of the lifting force, the culture dish 10 enters the feed hole 110 corresponding to the current receiving cavity 121. At this time, the one-way passage component 400 matching the feed hole 110 is in the open state due to the upward movement of the culture dish 10, allowing the one-way passage component 400 to allow the culture dish 10 to pass through the feed hole 110 and enter the receiving cavity 121. After the culture dish 10 enters the receiving cavity 121, the one-way passage component 400 can prevent the culture dish 10 in the receiving cavity 121 from falling downward through the feed hole 110, thus achieving stable collection of the culture dish 10 in the receiving cavity 121. The pushing mechanism 200 and the lifting mechanism 300 repeat the above actions, so that the receiving cavity 121 is stacked and collected with culture dishes 10, thereby completing the feeding and collection of culture dishes 10. The one-way passage component 400 only allows the culture dish 10 to pass upward through the feed hole 110 into the receiving cavity 121, preventing the culture dish 10 already collected in the receiving cavity 121 from falling out due to its own weight when passing through the feed hole 110. This ensures that the receiving cavity 121 can stably collect the culture dish 10, and ultimately achieves continuous and stable feeding and collection of the culture dish 10.

[0025] refer to Figure 4 and Figure 6 The one-way passage component 400 includes multiple limiting blocks 410. Multiple mounting grooves 111 are provided on the inner side wall of the upper end of the material passage 110. One end of each of the multiple limiting blocks 410 is hinged to the inner wall of the multiple mounting grooves 111. The other end of each of the multiple limiting blocks 410 extends into the material passage 110. The multiple limiting blocks 410 can abut against the inner bottom wall of the multiple mounting grooves 111 under their own weight. The other end of each of the multiple limiting blocks 410 can abut against the upwardly moving culture dish 10, so that the culture dish 10 passes upward through the material passage 110 and enters the receiving cavity 121. The multiple limiting blocks 410 abut against the inner bottom wall of the multiple mounting grooves 111, so that the other end of each of the multiple limiting blocks 410 can support the culture dish 10 in the receiving cavity 121.

[0026] Understandably, in the initial state, under the action of their own gravity, the multiple limit blocks 410 abut against the inner bottom wall of the multiple mounting grooves 111 respectively, and the other end of the multiple limit blocks 410 extends into the material passage hole 110. Subsequently, the pushing mechanism 200 is activated, pushing the culture dish 10 to be collected at the pushing station 540 to the lifting station 530; then the lifting mechanism 300 is activated, pushing the culture dish 10 at the lifting station 530 upward. When the culture dish 10 contacts the other end of the multiple limiting blocks 410 in the feed hole 110, with the continuous action of the lifting force of the lifting mechanism 300, the culture dish 10 abuts against the other end of the multiple limiting blocks 410 and generates an upward pushing force on the other end of the multiple limiting blocks 410, causing the other end of the multiple limiting blocks 410 to swing upward. At this time, the multiple limiting blocks 410 are in the open state, the feed hole 110 is opened, and the culture dish 10 passes upward through the feed hole 110 and the other end of the multiple limiting blocks 410 and enters the receiving cavity 121. Once the culture dish 10 has completely passed through the feed hole 110 and entered the receiving cavity 121, the upward pushing force of the culture dish 10 on the multiple limiting blocks 410 disappears. The other ends of the multiple limiting blocks 410 swing downward again under their own weight, causing the other ends of the multiple limiting blocks 410 to extend back into the feed hole 110. At this time, the other ends of the multiple limiting blocks 410 are located at the bottom of the receiving cavity 121. The culture dish 10 in the receiving cavity 121 falls onto the other ends of the multiple limiting blocks 410 under its own weight. At this time, the other ends of the multiple limiting blocks 410 support the culture dish 10 in the receiving cavity 121, and the multiple limiting blocks 410 abut against the inner bottom wall of the multiple mounting grooves 111 respectively, preventing the other ends of the multiple limiting blocks 410 from continuing to swing downward, thereby preventing the culture dish 10 in the receiving cavity 121 from falling into the feed hole 110. When the receiving cavity 121 is already filled with stacked culture dishes 10, as a new culture dish 10 enters the receiving cavity 121, the culture dish 10, under the action of the lifting force, pushes the other ends of multiple limiting blocks 410 upwards. At this time, the other ends of the multiple limiting blocks 410 push the stacked culture dishes 10 in the receiving cavity 121 to move upwards synchronously, making room for the newly entering culture dish 10. After the new culture dish 10 passes through the feed hole 110 and enters the receiving cavity 121, the lifting mechanism 300 continues to push the new culture dish 10 upwards, so that the new culture dish 10 abuts against the stacked culture dishes 10 in the receiving cavity 121. After the new culture dish 10 disengages from abutting against the other ends of the multiple limiting blocks 410, the other ends of the multiple limiting blocks 410 swing down to reset and abut against the inner bottom wall of the multiple mounting grooves 111 respectively. Then, the lifting mechanism 300 lowers the culture dishes 10 stacked in the receiving cavity 121. After the output end of the lifting mechanism 300 is pulled out from the receiving cavity 121 and the feed hole 110, the culture dishes 10 stacked in the receiving cavity 121 are supported by the other end of multiple limiting blocks 410 to prevent the stacked culture dishes 10 from entering the feed hole 110 and falling.

[0027] In this embodiment of the invention, a torsion spring is provided between the limiting block 410 and the inner wall of the mounting groove 111. The torsion spring is used to drive the other end of the limiting block 410 to swing downward. In this embodiment of the invention, torsion springs are provided between multiple limiting blocks 410 and the inner walls of multiple mounting grooves 111. It can be understood that when the new petri dish 10 is pushed upward by the lifting mechanism 300 and pushes the other end of the limiting block 410 to swing upward, the torsion spring undergoes torsional deformation and stores elastic potential energy; when the petri dish 10 completely passes through the feed hole 110 and enters the receiving cavity 121 and disengages from the limiting block 410, the torsion spring releases its elastic potential energy, and the torsion spring drives the other end of the limiting block 410 to swing downward, so that the other end of the limiting block 410 re-enters the feed hole 110 and keeps the limiting block 410 abutting against the inner bottom wall of the mounting groove 111, so as to quickly complete the reset of the limiting block 410. On the other hand, under the action of the torsion spring, the limiting block 410 can remain abutted against the inner bottom wall of the mounting groove 111, preventing the limiting block 410 from shaking during the operation of the culture dish feeding device. In this embodiment of the present invention, the limiting block 410 is hinged to the inner wall of the mounting groove 111 by a hinge shaft, and the torsion spring is sleeved on the hinge shaft. The two elastic arms of the torsion spring are respectively connected to the limiting block 410 and the inner wall of the mounting groove 111.

[0028] refer to Figure 6 and Figure 7The petri dish feeding device also includes a support platform 510, which is mounted on the frame 500. The support platform 510 is provided with a linear guide groove 520. A lifting station 530 and a pushing station 540 are respectively located at both ends of the linear guide groove 520. The linear guide groove 520 is used to move the petri dish 10. A guide hole 521 is provided on the inner bottom wall of the linear guide channel 520. The extension direction of the guide hole 521 is parallel to the extension direction of the linear guide channel 520. The guide hole 521 is used for the output end of the pushing mechanism 200 to pass through, so that the pushing mechanism 200 can push the culture dish 10 at the pushing station 540 to the lifting station 530. A clearance hole 522 is provided on the inner bottom wall of the linear guide channel 520 corresponding to the lifting station 530. The clearance hole 522 is used for the output end of the lifting mechanism 300 to extend into, so that the lifting mechanism 300 can push the culture dish 10 at the lifting station 530 upward into the receiving cavity 121. It can be understood that when the culture dish feeding device is running, the turntable 100 rotates, so that one of the empty receiving cavities 121 on the turntable 100 rotates to above the lifting station 530. The handling robot moves the culture dish 10 from the temporary storage area to the linear guide 520 at the pushing station 540. The output end of the pushing mechanism 200 passes through the guide hole 521 on the bottom wall of the linear guide 520, and pushes the culture dish 10 along the linear guide 520 to the lifting station 530 and then resets. Next, the output end of the lifting mechanism 300 extends into the clearance hole 522 on the bottom wall of the linear guide 520 and lifts the culture dish 10 at the lifting station 530 upward and sends it into the upper receiving cavity 121. After that, the lifting mechanism 300 resets. The pushing mechanism 200 and the lifting mechanism 300 repeat the above actions to complete the feeding and collection of the culture dish 10.

[0029] refer to Figure 6 and Figure 7The feeding mechanism 200 includes a linear drive assembly 210 and a push rod 220. The linear drive assembly 210 is mounted on the frame 500. The lower end of the push rod 220 is connected to the output end of the linear drive assembly 210. The push rod 220 passes through a guide hole 521, and the upper end of the push rod 220 extends out of the guide hole 521. The linear drive assembly 210 can drive the push rod 220 to move towards the lifting position 530, so that the push rod 220 pushes the culture dish 10 at the feeding position 540 to the lifting position 530. In this embodiment of the present invention, the lifting mechanism 300 includes a lead screw motor 310, which is mounted on the frame 500. The lead screw of the lead screw motor 310 can extend into the clearance hole 522 and push the culture dish 10 at the lifting position 530 upward. Understandably, after the culture dish 10 to be collected is placed in the linear guide groove 520 at the feeding station 540, the linear drive assembly 210 drives the push rod 220 to move along the guide hole 521 toward the lifting station 530. After the upper end of the push rod 220 pushes the culture dish 10 to slide along the linear guide groove 520 to the lifting station 530, the linear drive assembly 210 drives the push rod 220 to reset, that is, the linear drive assembly 210 drives the push rod 220 to move and reset along the guide hole 521 toward the feeding station 540. Then the lead screw motor 310 starts, and the lead screw of the lead screw motor 310 passes through the clearance hole 522 at the corresponding lifting station 530 in the linear guide groove 520, so that the lead screw of the lead screw motor 310 pushes the culture dish 10 at the lifting station 530 upward and makes the culture dish 10 enter the receiving cavity 121. After that, the lead screw motor 310 drives the lead screw to reset downward and exit the clearance hole 522. The feeding mechanism 200 and the lifting mechanism 300 repeat the above actions to complete the feeding and collection of the culture dish 10.

[0030] In this embodiment of the invention, the linear drive assembly 210 can be a common lead screw and nut motor drive assembly, and the lower end of the push rod 220 is connected to the nut in the lead screw and nut motor drive assembly; the lead screw motor 310 is a common linear drive component, whose lead screw converts rotation into linear motion, which can precisely control the lifting height and speed, ensuring that the culture dish 10 is smoothly lifted to the designated position in the receiving cavity 121, which will not be further described here. (Reference) Figure 7A pusher block 320 is rotatably connected to the upper end of the lead screw of the lead screw motor 310. The lead screw of the lead screw motor 310 pushes the culture dish 10 upward through the pusher block 320. It can be understood that during the process of the lead screw motor 310 pushing the culture dish 10 upward through the pusher block 320, since the pusher block 320 is rotatably connected to the lead screw of the lead screw motor 310, the pusher block 320 can remain stationary relative to the culture dish 10, while the lead screw motor 310 can rotate relative to the pusher block 320, thus allowing the lead screw motor 310 to smoothly push the culture dish 10 upward. On the other hand, the pusher block 320 increases the contact area between the lead screw motor 310 and the culture dish 10, allowing the culture dish 10 to rise more smoothly. In this embodiment of the present invention, the lifting mechanism 300 can also be a common cylinder. The cylinder body is mounted on the frame 500, and the piston rod of the cylinder can pass through the clearance hole 522 and push the culture dish 10 upward.

[0031] refer to Figure 2 , Figure 3 and Figure 5 The turntable 100 is provided with multiple limiting components 120, which respectively enclose multiple receiving cavities 121. Multiple baffles 130 are rotatably connected to the turntable 100. Each of the limiting components 120 has an opening 122 on its periphery, which communicates with the receiving cavity 121 and allows the culture dish 10 to pass through. The multiple baffles 130 are respectively positioned corresponding to the multiple openings 122, and can block a portion of the opening 122. It is understood that the multiple limiting components 120 enclosing the receiving cavity 121 provide stable circumferential support for the stacked culture dishes 10, preventing the culture dishes 10 within the receiving cavity 121 from shaking during the feeding and collection process. The opening 122 on the outer wall (peripheral side) of the limiting component 120 communicates with the receiving cavity 121. When the culture dishes 10 in the receiving cavity 121 are full, the operator can remove the stacked culture dishes 10 from the receiving cavity 121 through the opening 122. In this embodiment of the invention, the opening 122 extends vertically, and multiple baffles 130 are parallel to the vertical direction. When it is not necessary to remove the culture dishes 10 from the receiving cavity 121, the operator can rotate the baffles 130 to bring them closer to the opening 122, so that the baffles 130 block part of the opening 122, thereby preventing the culture dishes 10 from falling out of the receiving cavity 121 through the opening 122. When it is necessary to remove the culture dishes 10 from the receiving cavity 121, the operator can rotate the baffles 130 away from the opening 122.

[0032] In this embodiment of the utility model, the lower end of the baffle plate 130 is provided with a first magnetic suction member, and the turntable 100 is provided with a second magnetic suction member.
