A stacked petri dish delivery system

Abstract

This invention discloses a stacked petri dish conveying system, belonging to the field of medical devices. During the movement of the receiving plate, it abuts against the actuating component, causing the actuating component to rotate relative to the upright plate, thereby pulling the traction rope. The traction rope pulls the main body of the chamber door to slide relative to the discharge port, opening the discharge port. The material located above the discharge port falls onto the receiving plate, and the receiving plate moves the material downward. During the movement, the material falls onto the platform assembly. Two driving components control two driving wheels to rotate in opposite directions, causing the platform assembly and the slide plate to move relative to the conveying frame. Two driving components control two driving wheels to rotate in the same direction, causing the platform assembly to rotate relative to the slide plate, thus rotating the material. Through a single discharge driving component, the receiving plate can be driven to move to receive the falling material, and the main body of the chamber door can be driven to slide to open the discharge port, allowing the material to fall one by one under the action of gravity. At the same time, the conveying structure can realize the rotation and linear movement of the petri dishes, making the liquid preparation process fully automated and the equipment small in size.

Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a stacked culture dish delivery system. Background Technology

[0002] Currently, in the field of assisted reproduction, the embryo culture process requires the prior preparation of culture dishes for embryo culture. This process is called solution preparation. The procedure involves using burette A to extract a certain amount of culture medium and burette B to extract a certain amount of mineral oil. Then, burette A is squeezed to drip the culture medium liquid into the culture dish in a specific arrangement. The amount of liquid dripped is determined by the number of squeezes, and the drip position is manually controlled. The size of the drip is also manually controlled by the operator through observation. Next, burette B is squeezed to drip a certain amount of mineral oil liquid, ensuring that the mineral oil completely covers the culture medium droplets to prevent water evaporation from the culture medium and affecting changes in the osmotic pressure. After dripping, the prepared culture dish is manually placed in a constant temperature and humidity incubator with a constant concentration of CO2. This allows the temperature of the culture medium in the dish to rise to the temperature of the incubator, and the pH value of the culture medium is adjusted to the optimal value using CO2 in the incubator.

[0003] In practice, this method of liquid preparation involves stacking empty culture dishes in the storage chamber. The empty culture dishes need to be manually removed one by one, and the liquid separator and mineral oil are dripped into the culture dishes separately. The culture dishes are then rotated and moved to facilitate the separation of the liquid separator and the coverage of the mineral oil, as well as to transport the culture dishes to the detection device. The entire process uses a combination of manual operation, rotating equipment, and moving equipment, resulting in low overall efficiency, large overall equipment size, and inconvenience in use. Summary of the Invention

[0004] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a stacked petri dish delivery system that is fully automated and has a small equipment size.

[0005] One of the objectives of this invention is achieved through the following technical solution:

[0006] A stackable petri dish conveying system includes a feeding structure and a conveying structure.

[0007] The feeding structure includes a storage bin, a support frame, a feeding drive assembly, and a bin door assembly. The storage bin includes a bottom plate and a receiving space above the bottom plate. The receiving space is used to receive stacked materials. The bottom plate has an opening communicating with the receiving space. The support frame has a discharge port. The bottom plate is installed on the support frame, and the discharge port is located below the opening. The bin door assembly includes a bin door body and a traction rope. The bin door body is slidably installed in the discharge port, and the traction rope is connected to the bin door body. The feeding drive assembly includes a feeding drive component, a vertical plate, a receiving plate, and a toggle component. The receiving plate is slidably installed on the vertical plate. The feeding drive component is drively connected to the receiving plate and drives the receiving plate to slide relative to the vertical plate to receive materials. The toggle component is rotatably installed on the vertical plate, and the traction rope is connected to the toggle component.

[0008] The conveying structure includes a conveyor frame, a slide plate slidably mounted on the conveyor frame, a platform assembly rotatably mounted on the slide plate, at least two drive wheels rotatably mounted on the conveyor frame, a first driven wheel rotatably mounted on the conveyor frame, a second driven wheel rotatably mounted on the slide plate, a drive member, and a conveyor belt. The conveyor frame extends below the support frame. The number of drive members is the same as the number of drive wheels. Each drive member is connected to a drive wheel and drives the drive wheel to rotate relative to the conveyor frame. The conveyor belt is sleeved on the drive wheel, the platform assembly, the first driven wheel, and the second driven wheel.

[0009] During the movement of the receiving plate, it abuts against the actuating member, causing the actuating member to rotate relative to the upright plate, thereby pulling the traction rope. The traction rope pulls the main body of the hopper door to slide relative to the discharge port, causing the discharge port to open. The material above the discharge port falls onto the receiving plate, and the receiving plate drives the material to move downward. During the movement, the material falls onto the platform assembly. The two driving members control the two driving wheels to rotate in opposite directions, causing the platform assembly and the slide plate to move relative to the conveyor frame. The two driving members control the two driving wheels to rotate in the same direction, causing the platform assembly to rotate relative to the slide plate, thus rotating the material.

[0010] Furthermore, the door assembly also includes a second elastic element and a guide rod. The guide rod is fixedly installed on the support frame and extends into the discharge port. The door body is slidably installed on the guide rod. The second elastic element is sleeved on the guide rod, and both ends of the second elastic element abut against the door body and the support frame, respectively. The elastic force of the second elastic element provides power for the door body to reset, thereby closing the discharge port.

[0011] Furthermore, the actuating component includes an actuating part and a traction part. The traction part extends from the actuating part and forms an acute angle with the actuating part. The intersection of the traction part and the actuating part is rotatably connected to the upright plate. The traction rope is connected to the end of the traction part, and the end of the actuating part abuts against the receiving plate.

[0012] Furthermore, the receiving plate includes a receiving portion, an extension portion, and an abutting portion. The extension portion is located between the receiving portion and the abutting portion. The receiving portion is parallel to the horizontal plane, the extension portion extends in a vertical direction, and the width of the abutting portion is greater than the width of the extension portion. When the receiving plate moves to a preset position, the abutting portion abuts against the actuating portion, causing the actuating element to rotate.

[0013] Furthermore, the unloading drive assembly also includes a transmission gear and a transmission rack. The transmission gear is fixed to the output end of the unloading drive component, and the transmission rack is fixed to the receiving plate. The transmission rack meshes with the transmission gear, and the unloading drive component drives the transmission gear to rotate, thereby driving the receiving plate to slide relative to the upright plate through the transmission rack.

[0014] Furthermore, there are two first driven wheels, with the two first driven wheels located on both sides of one end of the conveyor frame, and the two driving wheels located on both sides of the other end of the conveyor frame. The platform assembly is located in the area between the first driven wheels and the driving wheels.

[0015] Furthermore, the platform assembly is located on the side of the slide plate near the driving wheel, and the second driven wheel is located on the side of the slide plate near the first driven wheel.

[0016] Furthermore, there are two second driven wheels, the conveyor belt is a closed structure, and the conveyor belt sequentially passes through one driving wheel, one first driven wheel, one second driven wheel, another second driven wheel, another first driven wheel, another driving wheel, and the platform assembly returns to the initial driving wheel.

[0017] Furthermore, the platform assembly includes a bearing, a pulley, and a shelf. The bearing is rotatably mounted on the slide plate, the pulley is mounted on the bearing and cooperates with the conveyor belt, and the shelf is mounted on the pulley.

[0018] Furthermore, the platform assembly also includes a mounting plate, which includes a fixed end, an extension fixedly connected to the fixed end, and a bearing end fixedly connected to the extension. The fixed end is fixed to the upper surface of the pulley, the extension is located inside the pulley and extends vertically, and the bearing end is located inside the pulley and extends horizontally. The material falls inside the pulley and is located on the bearing end.

[0019] Compared to existing technologies, this invention, during the movement of the receiving plate, the actuating component causes the actuating component to rotate relative to the upright plate, thereby pulling the traction rope. The traction rope pulls the main body of the chamber door to slide relative to the discharge port, opening the discharge port. The material above the discharge port falls onto the receiving plate, and the receiving plate moves the material downward. During the movement, the material falls onto the platform assembly. The two driving components control the two drive wheels to rotate in opposite directions, causing the platform assembly and the slide plate to move relative to the conveyor frame. The two driving components also control the two drive wheels to rotate in the same direction, causing the platform assembly to rotate relative to the slide plate, thus rotating the material. Through the above design, a single feeding drive component can both drive the receiving plate to move upward to receive the falling material and simultaneously drive the main body of the chamber door to slide and open the discharge port, allowing the material to fall one by one under gravity. At the same time, the conveying structure can realize the rotation and linear movement of the culture dish, making the liquid preparation process fully automated and the equipment small in size.

[0037] like Figure 1 As shown, the stacked petri dish conveying system of the present invention includes a feeding structure 40 and a conveying structure 50. The stacked petri dish conveying system of the present invention feeds the stacked materials 300 one by one from the storage bin 42 onto the platform assembly 53 of the conveying structure 50, and the conveying structure 50 drives the materials 300 to move and rotate. In this embodiment, the materials 300 include petri dishes and a dish rack for placing multiple petri dishes.

[0038] Please continue reading. Figures 2 to 8 The feeding structure 40 includes a support frame 41, a storage bin 42, a feeding drive assembly 43, and a bin door assembly 44.

[0039] The support frame 41 includes a support plate 410 and multiple support rods 411. The support plate 410 is fixed to the top of the multiple support rods 411, forming an operating space at the bottom of the support plate 410. Specifically, the support plate 410 is parallel to the horizontal plane and has a material discharge port 4101. When the material discharge port 4101 is open, the material 300 above the material discharge port 4101 falls down. When the material discharge port 4101 is closed, the material 300 above the material discharge port 4101 is located in the storage bin 42 and cannot fall down. The support rods 411 are perpendicular to the support plate 410, and the multiple support rods 411 are evenly distributed.

[0040] The storage bin 42 is installed above the support frame 41 and is used to accommodate multiple materials 300. Specifically, the storage bin 42 includes a base plate 420, a handle 421, and limiting rods 422. The base plate 420 is detachably fixed above the support plate 410 and has an opening 4201 for the material 300 to pass through. The handle 421 is fixed to the upper surface of the base plate 420 for the user to grip when moving the storage bin 42. Specifically, there are two handles 421, which are symmetrically arranged about the opening 4201. There are multiple limiting rods 422, which are fixed to the base plate 420 and arranged around the opening 4201. The multiple limiting rods 422 form a receiving space 423, which extends vertically, and multiple materials 300 are stacked in the receiving space 423.

[0041] The unloading drive assembly 43 includes a vertical plate 430, an unloading drive component 431, a transmission gear 432, a transmission rack 433, a receiving plate 434, a connecting plate 435, a toggle component 436, a first elastic component 437, a first position detection component 438, and a second position detection component 439. The vertical plate 430 is located below the support frame 41, and the unloading drive component 431 is fixed to the vertical plate 430. In this embodiment, the unloading drive component 431 is a motor. The transmission gear 432 is fixed to the output end of the unloading drive component 431, and the transmission rack 433 is fixed to the receiving plate 434 through the plate body. The transmission rack 433 meshes with the transmission gear 432, and the unloading drive component 431 drives the transmission gear 432 to rotate, thereby driving the receiving plate 434 to slide relative to the vertical plate 430 through the transmission rack 433.

[0042] The receiving plate 434 includes a receiving portion 4340, an extension portion 4341, and an abutting portion 4342. The extension portion 4341 is located between the receiving portion 4340 and the abutting portion 4342. The receiving portion 4340, the extension portion 4341, and the abutting portion 4342 are integrally formed. The receiving portion 4340 is parallel to the horizontal plane, the extension portion 4341 extends vertically, and the width of the abutting portion 4342 is greater than the width of the extension portion 4341. The receiving portion 4340 is used to receive the material 300 falling from the discharge port 4101 and drive the material 300 to move vertically. The abutting portion 4342 is used to actuate the actuating members 436 on both sides. Specifically, when the receiving plate 434 moves to a preset position, the abutting portion 4342 abuts against the actuating portion 4360, causing the actuating member 436 to rotate.

[0043] The connecting plate 435 is fixed to the top of the upright plate 430.

[0044] There are two actuating elements 436, which are rotatably mounted on the connecting plate 435 and located on opposite sides of the receiving plate 434.

The traction part 4361 extends from the actuating part 4360, and the traction part 4361 forms an acute angle with the actuating part 4360. The intersection of the traction part 4361 and the actuating part 4360 is rotatably connected to the connecting plate 435. The traction rope 445 is connected to the end of the traction part 4361, and the end of the actuating part 4360 abuts against the receiving plate 434.

[0045] There are two first elastic elements 437. Each first elastic element 437 is connected at one end to the actuating part 4360 and at the other end to the connecting plate 435. The first elastic element 437 provides the spring force for the actuating part 436 to return to its original position. Specifically, the first elastic element 437 is a spring.

[0046] There are two actuating components 436, bin door body 440 and traction rope 445. The actuating components 436, bin door body 440 and traction rope 445 are symmetrically arranged. The two bin door bodies 440 move in opposite directions when closing and opening, so that the material discharge port 4101 opens and closes quickly.

[0047] The first position detection component 438 includes a first sensor 4380 and a first baffle 4381. The first baffle 4381 is fixed to the traction part 4361, and the first sensor 4380 is fixed to the upright plate 430. The first baffle 4381 rotates with the actuating member 436 to trigger the first sensor 4380. The first sensor 4381 senses the position of the traction part 4361 to determine the position of the hopper body 440 in the discharge port 4101.

[0048] The second position detection component 439 includes a second sensor 4390 and a second baffle 4391. The second sensor 4390 is fixed to the upright plate 430, and the second baffle 4391 is fixed to the receiving plate 434. The second baffle 4391 moves with the receiving plate 434. When the receiving plate 434 moves to a preset position, the second baffle 4391 triggers the second sensor 4390 to detect the position of the receiving plate 434.

[0049] The door assembly 44 includes a door body 440, a connecting block 441, a second elastic element 443, a guide rod 444, a traction rope 445, and a roller 446.

A guide rod 444 is fixedly installed on the support frame 41 and extends into the discharge port 4101. The door body 440 is slidably installed on the guide rod 444. A second elastic element 443 is sleeved on the guide rod 444 and located between the door body 440 and the support frame 41. The two ends of the second elastic element 443 abut against the door body 440 and the support frame 41, respectively. The elastic force of the second elastic element 443 provides power for the door body 440 to reset, causing the discharge port 4101 to close. Specifically, the second elastic element 443 is a spring.

[0051] Roller 446 is rotatably mounted on support frame 41, and traction rope 445 is wound around roller 446. Roller 446 changes the traction direction of traction rope 445. One end of traction rope 445 is connected to connecting block 441, and the other end is connected to traction part 4361 of actuating member 436.

[0053] The conveyor frame 51 includes uprights 511, extension plates 512, slide rails 513, and mounting bases 514. Multiple uprights 511 are evenly distributed and perpendicular to the horizontal plane. Extension plates 512 are fixedly mounted on the top of the uprights 511, and are straight, arranged along the conveying direction. Two slide rails 513 are fixed to both sides of the extension plate 512 and are parallel to each other.

Multiple mounting plates 533 are evenly mounted on the pulley 532 and extend into the interior of the pulley 532. Specifically, each mounting plate 533 includes a fixing part 5330, an extension section 5331, and a support part 5332. The fixing part 5330 is fixed to the top of the pulley 532, and the extension section 5331 extends from the fixing part 5330 and is perpendicular to the fixing part 5330. The extension section 5331 extends vertically, and the support part 5332 extends from the extension section 5331 and is perpendicular to the extension section 5331. The support part 5332 is located inside the pulley 532 and at its lowest point. The pulley 532 is generally annular.

[0056] The conveyor belt 54 is a tightly sealed structure with its ends connected. The conveyor belt 54 is fitted onto the drive wheel 56, the platform assembly 53, the first driven wheel 57, and the second driven wheel 58. The conveyor belt 54 plays the role of transmitting power.

[0057] There are two drive components 55, which are mounted on the extension plate 512. Each drive component 55 drives a drive wheel 56 to rotate relative to the extension plate 512. Specifically, each drive component 55 includes a motor and a reducer connected to the motor.

[0058] There are two drive wheels 56, each of which is connected to a drive component 55. The two drive wheels 56 are located on both sides of one end of the extension plate 512.

[0059] There are two first driven wheels 57, which are rotatably mounted on the conveyor frame 51 and located on both sides of the other end of the conveyor frame 51. The platform assembly 53 is located in the area between the first driven wheels 57 and the driving wheel 56. The platform assembly 53 is located on the side of the slide plate 52 near the driving wheel 56, and the second driven wheel 58 is located on the side of the slide plate 52 near the first driven wheel 57.

[0063] Please continue reading Figure 13 When using the stacked petri dish conveying system of the present invention, the material 300 is stacked vertically in the receiving space 423. In the initial state, the main body of the door 440 is in a closed state. When it is necessary to unload the material, the unloading drive 431 drives the transmission gear 432 to rotate. The transmission gear 432 meshes with the transmission rack 433, and the transmission rack 433 drives the receiving plate 434 to slide relative to the upright plate 430. During the movement of the receiving plate 434, it abuts against the actuating member 436, causing the actuating member 436 to rotate relative to the upright plate 430, thereby pulling the traction rope 445. The traction rope 445 pulls the main body of the silo door 440 to slide relative to the discharge port 4101, causing the discharge port 4101 to open. The material 300 located above the discharge port 4101 falls onto the receiving plate 434. The feeding drive member 431 rotates in the opposite direction, and the receiving plate 434 drives the material 300 to move down. During the movement, the material 300 falls onto the bearing end 5332 of the platform assembly 53. The elastic force of the first elastic member 437 causes the actuating member 436 to reverse, and the elastic force of the second elastic member 443 causes the main body of the silo door 440 to slide in the opposite direction relative to the discharge port 4101, closing the discharge port 4101. Two drive units 55 control two drive wheels 56 to rotate in opposite directions, causing the platform assembly 53 and slide plate 52 to move relative to the conveyor frame 51. A third position detection unit 59 detects the positions of the platform assembly 53 and slide plate 52. Alternatively, two drive units 55 can control two drive wheels 56 to rotate in the same direction, causing the platform assembly 53 to rotate relative to the slide plate 52. For detailed control specifications, please refer to the platform assembly motion table.

[0066] Through the above design, the present invention uses a feeding drive component 431 to drive the receiving plate 434 to move upward to receive the falling material 300, and at the same time drive the main body of the silo door 440 to slide so that the feeding port 4101 opens, so that the material 300 falls one by one onto the receiving plate 434 under the action of gravity and moves downward onto the bearing end 5332 of the platform assembly 53. At the same time, the conveying structure 50 can realize the rotation and linear movement of the culture dish, so that the liquid preparation process can be fully automated and the equipment is small in size.

The feeding drive assembly includes a feeding drive component, a vertical plate, a receiving plate, and a toggle component. The receiving plate is slidably installed on the vertical plate. The feeding drive component is drively connected to the receiving plate and drives the receiving plate to slide relative to the vertical plate to receive materials. The toggle component is rotatably installed on the vertical plate, and the traction rope is connected to the toggle component. The conveying structure includes a conveyor frame, a slide plate slidably mounted on the conveyor frame, a platform assembly rotatably mounted on the slide plate, at least two drive wheels rotatably mounted on the conveyor frame, a first driven wheel rotatably mounted on the conveyor frame, a second driven wheel rotatably mounted on the slide plate, a drive member, and a conveyor belt. The conveyor frame extends below the support frame. The number of drive members is the same as the number of drive wheels. Each drive member is connected to a drive wheel and drives the drive wheel to rotate relative to the conveyor frame. The conveyor belt is sleeved on the drive wheel, the platform assembly, the first driven wheel, and the second driven wheel. During the movement of the receiving plate, it abuts against the actuating member, causing the actuating member to rotate relative to the upright plate, thereby pulling the traction rope. The traction rope pulls the main body of the hopper door to slide relative to the discharge port, causing the discharge port to open. The material above the discharge port falls onto the receiving plate, and the receiving plate drives the material to move downward. During the movement, the material falls onto the platform assembly. The two driving members control the two driving wheels to rotate in opposite directions, causing the platform assembly and the slide plate to move relative to the conveyor frame. The two driving members control the two driving wheels to rotate in the same direction, causing the platform assembly to rotate relative to the slide plate, thus rotating the material.
