Description

Technical Field

[0001] This invention relates to the field of medical devices, and in particular to a stacking-type unloading structure. 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 placed into the pipetting structure. Then, the culture medium and mineral oil are dripped into the empty culture dishes. The whole process is inefficient. 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 stacking feeding structure that can store petri dishes, occupy little space, and enable the petri dishes to fall automatically one by one from the hopper.

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

[0006] A stacking-type unloading structure includes a storage bin, which includes a base plate and a receiving space above the base plate for receiving stacked materials. The base plate has an opening communicating with the receiving space. The stacking-type unloading structure also includes a support frame, a unloading drive assembly, and a bin door assembly. The support frame has a discharge port, the base plate is mounted 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 drive assembly includes a feeding drive component, a vertical plate, a receiving plate, and a toggle component. The receiving plate is slidably mounted 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 mounted on the vertical plate. The traction rope is connected to the toggle component. During the movement of the receiving plate, it abuts against the toggle component, causing the toggle component to rotate relative to the vertical plate, thereby pulling the traction rope. The traction rope pulls the hopper door body to slide relative to the discharge port, causing the discharge port to open, and the materials located above the discharge port fall onto the receiving plate.

[0007] Furthermore, the door assembly also includes a second elastic element, the two ends of which 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.

[0008] Furthermore, the hopper door assembly also includes a guide rod, which is fixedly installed on the support frame and extends into the discharge port. The hopper door body is slidably installed on the guide rod, and the second elastic element is sleeved on the guide rod and located between the hopper door body and the support frame.

[0009] Furthermore, the door assembly also includes a roller, which is rotatably mounted on the support frame, and the traction rope is wound around the roller, with the roller changing the traction direction of the traction rope.

[0010] 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.

[0011] 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.

[0012] Furthermore, the material feeding drive assembly also includes a first position detection assembly, which includes a first sensor and a first baffle. The first baffle is fixed to the traction part, and the first sensor is fixed to the upright plate. The first baffle rotates with the actuating member to trigger the first sensor. The first sensor senses the position of the traction part to determine the position of the hopper door body in the material feeding port.

[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, the feeding drive assembly also includes a second position detection assembly, which includes a second sensor and a second baffle. The second sensor is fixed to the upright plate, and the second baffle is fixed to the receiving plate. The second baffle moves with the receiving plate. When the receiving plate moves to a preset position, the second baffle triggers the second sensor to detect the position of the receiving plate.

[0015] Furthermore, there are two of the actuating element, the main body of the compartment door, and the traction rope, and the actuating element, the main body of the compartment door, and the traction rope are arranged symmetrically.

[0016] Compared to existing technologies, the storage bin of the stacked feeding structure of this invention has an opening on its bottom plate that communicates with the receiving space. The stacked feeding structure also includes a support frame, a feeding drive assembly, and a bin door assembly. The support frame has a discharge port, and the bottom plate is installed on the support frame. 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, and the feeding drive component is connected to the receiving plate in a transmission manner. The receiving plate slides relative to the upright plate to receive materials. The actuating component is rotatably mounted on the upright plate. The traction rope is connected to the actuating component. 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 hopper door to slide relative to the discharge port, causing the discharge port to open. The materials located above the discharge port fall onto the receiving plate. Through the above design, a single driving component can both drive the receiving plate to move upward to receive the falling materials and simultaneously drive the main body of the hopper door to slide and open the discharge port, allowing the materials to fall one by one under the action of gravity.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] like Figures 1 to 7 As shown, the stacking feeding structure of the present invention feeds the stacked materials 300 one by one. In this embodiment, the materials 300 include petri dishes and a rack for placing multiple petri dishes.

[0029] The stacking unloading structure includes a support frame 41, a storage bin 42, an unloading drive assembly 43, and a bin door assembly 44.

[0030] 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.

[0031] 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.

[0032] 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.

[0033] 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.

[0034] The connecting plate 435 is fixed to the top of the upright plate 430.

[0035] 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. Each actuating element 436 includes an actuating part 4360 and a traction part 4361. 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.

[0036] 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.

[0037] 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.

[0038] 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.

[0039] 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.

[0040] 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.

[0041] There are two door bodies 440, which are slidably installed inside the discharge port 4101. Each door body 440 is fixedly connected to a connecting block 441. 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.

[0042] 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.

[0043] When using a stacking-type unloading structure, 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 unloading is required, 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 downward. 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.

[0044] Through the above design, a single driving component can both drive the receiving plate 434 to move upward to receive the falling material 300 and simultaneously drive the main body of the silo door 440 to slide and open the discharge port 4101, allowing the material 300 to fall one by one under the action of gravity. The overall structure is simple, compact, and occupies little space.

[0045] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of the present invention, and all of these fall within the protection scope of the present invention.
