Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a gripping component and medical device. Background Technology

[0002] Taking PCR experiments as an example, the experimental process requires the use of the PCR plate and its lid. The PCR plate contains the PCR reaction system, while the lid seals the plate to prevent liquid evaporation and cross-contamination during the reaction. The handling of the PCR plate and lid is a crucial step in the laboratory automation process.

[0003] Most existing gripping components only use grippers or similar structures to grasp PCR plates or caps, thus only performing a single gripping function. While this can meet the gripping needs for different PCR plates or caps, additional manual intervention is still required when stacking PCR plates or caps to count the number of plates or caps being placed and the number already gripped, increasing operation time and reducing work efficiency. Utility Model Content

[0004] The main purpose of this invention is to propose a gripping component and a medical device, which aims to realize the automatic counting function of the gripping component, so as to calculate the quantity of materials placed at the gripping component placement position and the quantity of materials already gripped during the gripping process, thereby improving work efficiency.

[0005] To achieve the above objectives, the present invention proposes a gripping component for gripping materials stacked at a placement position, comprising:

[0006] The mounting base is movably positioned above the placement location to be close to or away from the material;

[0007] A clamping structure is provided on the mounting base to clamp or release the material; and

[0008] A counting structure, located on the mounting base, is used to calculate the real-time quantity of the material placed at the placement position and the quantity of the material that has been grabbed.

[0009] In one embodiment, the counting structure includes:

[0010] Processing unit;

[0011] The detection element is disposed on the mounting base and electrically connected to the processing unit; and

[0012] The trigger element is vertically mounted on the mounting base. When the clamping structure grips the material, the material can drive the trigger element to move closer to the detection element.

[0013] In one embodiment, the detection element is configured as a slotted photoelectric switch, which is located above the trigger and the slot of the slotted photoelectric switch faces the trigger. When the trigger comes into contact with the material, it is driven by the reverse force of the material to move to the slot of the slotted photoelectric switch.

[0014] In one embodiment, the counting structure further includes:

[0015] The first elastic element elastically connects the trigger element and the mounting base.

[0016] In one embodiment, the counting structure further includes:

[0017] A baffle is provided on the mounting base and located between the detection element and the trigger. The baffle has a clearance opening opposite to the detection element. One end of the first elastic element is connected to the baffle, and the other end of the first elastic element is connected to the trigger. The trigger can squeeze the first elastic element and pass through the clearance opening.

[0018] In one embodiment, the counting structure further includes:

[0019] A fixed sleeve is disposed on the mounting base and located below the detection element. The fixed sleeve has a guide channel opposite to the clearance opening. The first elastic element is sleeved on the outer periphery of the trigger element and connected to the trigger element. The trigger element and the first elastic element are movably inserted through the guide channel.

[0020] In one embodiment, a limiting member protrudes from the outer side wall of the fixing sleeve, the limiting member being able to abut against the clamping structure to restrict the movement of the clamping structure.

[0021] In one embodiment, the counting structure further includes:

[0022] A limiting structure is provided between the trigger and the mounting base to limit the lifting stroke of the trigger.

[0023] In one embodiment, the material includes a first workpiece and a second workpiece. The clamping structure has a clamping portion at one end away from the mounting base. The clamping portion has a groove and a contact surface in sequence in the direction away from the mounting base. The groove is used to engage with the periphery of the first workpiece, and the contact surface is used to abut against the outer peripheral surface of the second workpiece.

[0024] This invention also proposes a medical device comprising a gripping component as described in any of the above embodiments.

[0025] The technical solution of this utility model incorporates a mounting base, a clamping structure, and a counting structure within the gripping component. The mounting base is movably positioned above the placement position to move closer to or away from the material. The clamping structure is located on the mounting base to clamp or release the material. The counting structure, also located on the mounting base, is used to calculate the real-time quantity of material placed at the placement position and the quantity of material already gripped. Compared to existing gripping components that rely solely on grippers to grasp material, this utility model incorporates a counting structure. This counting structure automatically calculates the quantity of material currently placed at the placement position and the quantity of material already gripped by the gripping component each time it grips material, eliminating manual calculations and improving work efficiency.

[0041] Taking PCR experiments as an example, the experimental process requires the use of the PCR plate and its lid. The PCR plate contains the PCR reaction system, while the lid seals the plate to prevent liquid evaporation and contamination during the reaction. The handling of the PCR plate and lid is a crucial step in the laboratory automation process.

[0042] Most existing gripping components only use grippers or similar structures to grasp PCR plates or caps, thus only performing a single gripping function. While this can meet the need for precise gripping of different PCR plates or caps, additional manual intervention is still required when stacking PCR plates or caps to count the number of plates or caps being placed and the number already gripped. This increases operation time and reduces work efficiency.

[0043] This invention proposes a gripping component to achieve an automatic counting function, which calculates the real-time quantity of materials placed at the placement position and the quantity of materials already gripped during the gripping process, thereby improving work efficiency.

[0044] Please see Figures 1 to 5 In one embodiment, the gripping component includes a mounting base 100, a clamping structure 200, and a counting structure 300. The mounting base 100 is movably disposed above the placement position to approach or move away from the material. The clamping structure 200 is disposed on the mounting base 100 to clamp or release the material. The counting structure 300 is disposed on the mounting base 100 and is used to calculate the real-time quantity of the material placed at the placement position and the quantity of the material that has been gripped.

[0045] The gripping component is mainly used to grip materials stacked in the placement position. The materials are stacked in the placement position, and the materials can be PCR plate body 01, PCR plate cover 02, or a combination of PCR plate body 01 and PCR plate cover 02. There are no restrictions here.

[0046] The mounting base 100 provides a mounting foundation for the gripping component. The mounting base 100 is arranged parallel to the placement position in the Z-axis direction, and has an initial position directly above the placement position. The mounting base 100 can move up and down relative to the placement position along the Z-axis to approach or move away from the material, thus gripping it. Furthermore, the mounting base 100 can also translate relative to the placement position in a direction perpendicular to the Z-axis to approach or move away from the placement position after gripping the material, thus transporting it. In other embodiments, the mounting base 100 can also rotate about the Z-axis to reverse direction when gripping or releasing the material. The lifting and translating movements of the mounting base 100 can be achieved using structures such as linear modules, and the rotational movement can be achieved using structures such as rotary motors; no limitations are imposed here.

[0047] The clamping structure 200 is used to clamp materials. Specifically, the clamping structure 200 includes a power component 220, a transmission component, and two grippers 210 disposed on the mounting base 100. The mounting base 100 has a receiving cavity inside, the transmission component is disposed in the receiving cavity, one end of each gripper 210 extends into the receiving cavity, and the power component 220 extends at least partially into the receiving cavity and is drivenly connected to the two grippers 210 through the transmission component. The transmission component includes a gear 232 and two racks 231. The two racks 231 are slidably disposed on two opposite cavity walls of the receiving cavity via linear guides 240 and are respectively connected to one gripper 210. The gear 232 is fixedly sleeved on the output shaft of the power component 220 and located between the two racks 231, and the gear 232 meshes with the two racks 231. When the output shaft of the power component 220 rotates, it can drive the gear 232 to rotate, thereby driving the two racks 231 to slide in a direction away from or towards each other, realizing that the two grippers 210 move away from or towards each other. Furthermore, the clamping structure 200 also includes a guide rod 250 disposed in the receiving cavity and two second elastic members 260 sleeved on the guide rod 250. The guide rod 250 is movably inserted through one end of the two grippers 210 that extends into the receiving cavity. The ends of the two second elastic members 260 that are close to each other abut against the opposite sides of the two grippers 210, and the ends of the two second elastic members 260 that are far apart from each other abut against the two opposite cavity walls of the receiving cavity, thereby driving the two grippers 210 to move closer to each other. This allows the two grippers 210 to remain clamped in the event of a malfunction or power outage of the power component 220, preventing the currently clamped material from falling. The power component 220 can be configured as a motor, etc., and the second elastic members 260 can be configured as springs or silicone sleeves, etc., without limitation.

[0048] The counting structure 300 is used to count the quantity of materials placed in the placement position and the quantity of materials already grasped in real time during the grasping process. The counting structure 300 is located in the mounting base 100 and between the two grippers 210. It can be triggered every time the grippers 210 grasp materials to calculate the quantity of materials placed in the placement position in real time and simultaneously calculate the quantity of materials already grasped.

[0049] The technical solution of this utility model includes a mounting base 100, a clamping structure 200, and a counting structure 300 in the gripping component. The mounting base 100 is movably positioned above the placement position to move closer to or further away from the material. The clamping structure 200 is located on the mounting base 100 to clamp or release the material. The counting structure 300 is located on the mounting base 100 and is used to calculate the real-time quantity of material placed in the placement position and the quantity of material already gripped. Compared to existing gripping components that only use the gripper 210 to grip material, the technical solution of this utility model includes a counting structure 300. The counting structure 300 automatically calculates the quantity of material placed in the current placement position and the quantity of material already gripped by the gripping component each time it grips material, avoiding manual calculation and improving work efficiency.

[0050] Please see Figures 2 to 4 In one embodiment, the counting structure 300 includes a processing unit, a detection element, and a trigger 320. The detection element is disposed on the mounting base 100 and electrically connected to the processing unit. The trigger 320 is vertically mounted on the mounting base 100. When the clamping structure 200 clamps the material, the material can drive the trigger 320 to move closer to the detection element.

[0051] Materials are stacked in the placement positions, and the processing unit will pre-store the total number of materials that can be stacked in each placement position and the height of each individual material in the stack in the Z-axis direction.

[0052] When material is first grasped at the placement position, the mounting base 100 moves downward along the Z-axis from its initial position until the trigger 320 comes into contact with the material and moves closer to the detection element under the reaction force, thus triggering the detection element. At this time, the detection element is triggered, indicating that there is material at the Z-axis position. The power unit 220 drives the two grippers 210 to grasp a single piece of material. The detection element outputs a real-time signal to the processing unit. The processing unit identifies the real-time position of the mounting base 100 in the Z-axis direction. The current real-time position is the initial stacking height of the material in the Z-axis direction. Alternatively, the processing unit calculates the initial stacking height of the material based on the difference between the travel distance of the mounting base 100 in the Z-axis direction and the initial position. The processing unit can calculate the actual quantity of material placed at the placement position based on the initial stacking height and the height of a single material.

[0053] The above steps are repeated each time material is grabbed from the placement position. When the detection element outputs a real-time signal to the processing unit, the processing unit identifies the real-time position of the mounting base 100 in the Z-axis direction. The current real-time position is the real-time stacking height of the material pile in the Z-axis direction. Alternatively, the processing unit calculates the real-time stacking height of the material pile based on the difference between the real-time movement distance of the mounting base 100 in the Z-axis direction and its initial position. The processing unit can calculate the actual quantity of material currently placed at the placement position based on the real-time stacking height and the height of individual materials. Simultaneously, the processing unit can calculate the real-time quantity of material grabbed based on the real-time stacking height, the initial stacking height, and the height of individual materials. Specifically, the difference between the initial stacking height and the real-time position is the total height of the grabbed material in the Z-axis direction. The quantity of grabbed material can be obtained by calculating the ratio of the total height to the height of individual materials. Furthermore, if the mounting base 100 moves downward along the Z-axis from its initial position while material is being grabbed, and the detection element is not triggered, it indicates that the placement position is short of material, allowing staff to replenish materials promptly.

[0054] The detection element and trigger 320 are located between the two grippers 210 to ensure that the trigger 320 can contact the material when the two grippers 210 grip the material; the processing unit can be configured as a processor, etc. The function of the processing unit is mainly implemented through logic algorithms, which are not limited here.

[0055] Please see Figures 2 to 4 In one embodiment, the detection element is configured as a slotted photoelectric switch 310, which is located above the trigger 320 and the slot of the slotted photoelectric switch 310 faces the trigger 320. When the trigger 320 comes into contact with the material, it is driven by the reverse force of the material to move to the slot of the slotted photoelectric switch 310.

[0056] The trigger element 320 has a rod-shaped structure. One end of the trigger element 320 faces the placement position and can abut against the material. The other end of the trigger element 320 can extend into the slot of the slot-shaped photoelectric switch 310 to block the light path of the slot-shaped photoelectric switch 310, thus triggering the slot-shaped photoelectric switch 310 to output a real-time signal to the processing unit. The top of the material has a detection surface for abutting against the trigger element 320. The length of the trigger element 320 can be flexibly set according to actual needs and is not limited here. Of course, in other embodiments, the detection element can also be a proximity switch, etc., as long as it can detect the position change of the trigger element 320 and output a real-time signal to the processing unit; this is not limited here. The slot-shaped photoelectric switch 310 has a long detection distance, fewer restrictions on the detected object, and a fast response speed. The slot-shaped photoelectric switch 310 is a preferred embodiment of the detection element. The following description uses the slot-shaped photoelectric switch 310 as the detection element.

[0057] In the technical solution of this utility model embodiment, by setting a detection element and a trigger 320, the trigger 320 can trigger the detection element in a timely manner to realize the detection of the position and trigger the counting action, so that the processing unit can calculate the real-time quantity of the material placed at the placement position and the quantity of the material already grasped in a timely and accurate manner during the grasping process, realizing automatic counting, avoiding the tediousness and error of manual calculation, and improving work efficiency and accuracy.

[0058] Please see Figure 3 and Figure 4 In one embodiment, the counting structure 300 further includes a first elastic member 330, an elastic connection trigger member 320, and a mounting base 100.

[0059] In the initial state, when the trigger 320 is not in contact with the material, under the driving force of the first elastic element 330 and its own gravity, the trigger 320 tends to move away from the detection element. When grasping the material, the trigger 320 comes into contact with the material and squeezes the first elastic element 330 under the reaction force. The trigger 320 moves closer to the slotted photoelectric switch 310 and triggers the slotted photoelectric switch 310. After the grasping is completed, the trigger 320 loses the reaction force from the material and resets under the driving force of the first elastic element 330 and the gravity of the trigger 320, so that the slotted photoelectric switch 310 can be triggered again in the next grasping.

[0060] Specifically, in one embodiment, the counting structure 300 further includes a baffle 340 disposed on the mounting base 100 and located between the detection element and the trigger 320. The baffle 340 has a clearance opening opposite to the detection element. One end of the first elastic member 330 is connected to the baffle 340, and the other end of the first elastic member 330 is connected to the trigger 320. The trigger 320 can squeeze the first elastic member 330 and pass through the clearance opening.

[0061] The baffle 340 is positioned close to the slotted photoelectric switch 310, with its clearance opening opposite the slot of the slotted photoelectric switch 310. One end of the first elastic member 330 is connected to the side of the baffle 340 facing away from the slotted photoelectric switch 310, and the other end of the first elastic member 330 is connected to the middle position of the trigger member 320. This allows the trigger member 320 to press against the first elastic member 330, and the end of the trigger member 320 near the slotted photoelectric switch 310 can pass through the clearance opening and trigger the slotted photoelectric switch 310. The first elastic member 330 can be configured as a spring, silicone, or rubber, etc., and there are no restrictions on its use.

[0062] Please see Figures 2 to 4In one embodiment, the counting structure 300 further includes a fixed sleeve 350, which is disposed on the mounting base 100 and located below the detection element. The fixed sleeve 350 is provided with a guide channel 351 opposite to the clearance opening. The first elastic member 330 is sleeved on the outer periphery of the trigger member 320 and connected to the trigger member 320. The trigger member 320 and the first elastic member 330 are movably inserted through the guide channel 351.

[0063] A fixed sleeve 350 is located between two grippers 210, and two extensions 352 are provided at intervals at one end of the fixed sleeve 350 facing the slotted photoelectric switch 310. The two extensions 352 are respectively connected to the mounting base 100 through a bracket 360. The slotted photoelectric switch 310 is fixed to the extensions 352 and located between the two brackets 360. A baffle 340 is located between the slotted photoelectric switch 310 and the fixed sleeve 350 and is connected to the fixed sleeve 350. A guide channel 351 extends along the Z-axis and is opposite to the clearance opening and the slot of the slotted photoelectric switch 310. A first elastic member 330 is sleeved on the outer periphery of the trigger member 320, and the end of the first elastic member 330 away from the baffle 340 is connected to the trigger member 320, so that the trigger member 320 can squeeze the first elastic member 330 when the guide channel 351 moves toward the slotted photoelectric switch 310, and the first elastic member 330 can drive the trigger member 320 to reset.

[0064] The technical solution of this utility model embodiment provides a stable and reliable guiding and resetting mechanism for the trigger 320 by setting a first elastic element 330, a baffle 340, and a fixed sleeve 350. This allows the trigger 320 to quickly reset after losing the material reaction force, preparing for the next gripping and ensuring that rapid and accurate counting can be achieved in each gripping. At the same time, it allows the trigger 320 to move accurately along the guide channel 351 of the fixed sleeve 350, ensuring stable contact with the material and improving the overall stability and reliability of the gripping component.

[0065] Please see Figure 3 and Figure 5 In one embodiment, a limiting member 353 protrudes from the outer side wall of the fixing sleeve 350, and the limiting member 353 can abut against the clamping structure 200 to restrict the movement of the clamping structure 200.

[0066] Specifically, each of the two opposite outer sidewalls of the fixed sleeve 350 is provided with a limiting member 353. Each limiting member 353 can abut against a gripper 210 to restrict the movement of the gripper 210 and prevent damage to the counting structure 300 when the grippers 210 come close together. The limiting member 353 can be configured as a protrusion, a limiting bolt, or a buffer pad, etc., and is not limited here. In this way, the limiting member 353 can provide protection for the main functional parts of the counting structure 300, ensuring the realization of the counting function.

[0067] Please see Figure 3 and Figure 4 In one embodiment, the counting structure 300 further includes a limiting structure disposed between the trigger 320 and the mounting base 100, for limiting the lifting stroke of the trigger 320.

[0068] Specifically, the limiting structure includes a first protrusion 371 and a second protrusion 372. The first protrusion 371 protrudes from the outer periphery of the trigger member 320 and is located in the middle of the trigger member 320. The second protrusion 372 protrudes from the inner wall of the guide channel 351. The first protrusion 371 can abut against the second protrusion 372 to limit the lifting stroke of the trigger member 320. The outer diameter of the first protrusion 371 is greater than or equal to the outer diameter of the first elastic member 330, so that the first elastic member 330 is always located between the first protrusion 371 and the baffle 340. The first elastic member 330 can be fixedly connected to or abut against the first protrusion 371 to ensure that when the trigger member 320 approaches the slotted photoelectric switch 310, it can squeeze the first elastic member 330, thereby enabling the first elastic member 330 to drive the trigger member 320 to reset. The second protrusion 372 enables the guide channel 351 to have a first channel and a second channel that are connected. The second channel is located at the end of the first channel away from the baffle 340. The inner diameter of the first channel is larger than the outer diameter of the first protrusion 371, and the first protrusion 371 can move within the first channel. The inner diameter of the second channel is smaller than the outer diameter of the first protrusion 371 to prevent the first protrusion 371 from entering the second channel.

[0069] In the initial state, the lower end face of the first protrusion 371 abuts against the upper end face of the second protrusion 372, and the trigger 320 approaches the clearance opening at one end toward the slotted photoelectric switch 310 to ensure that the trigger 320 can quickly penetrate the clearance opening to trigger the slotted photoelectric switch 310 when it comes into contact with the material. When the material drives the trigger 320 to move closer to the slotted photoelectric switch 310, the first protrusion 371 moves away from the second protrusion 372 simultaneously. In this way, the first protrusion 371 can cooperate with the second protrusion 372 to limit the travel of the trigger 320 in the direction away from the slotted photoelectric switch 310. Of course, in other embodiments, two second protrusions 372 may be provided, and the first protrusion 371 moves between the two second protrusions 372; the limiting structure may also include limiting grooves and protrusions, etc., which are not limited here.

[0070] The technical solution of this utility model embodiment limits the lifting stroke of the trigger 320 by setting a limiting structure, so that the trigger 320 can accurately and timely trigger the counting action in each grasping process; and the first protrusion 371 and the second protrusion 372 cooperate to limit the movement of the trigger 320 away from the slotted photoelectric switch 310, while preventing the trigger 320 from falling off the fixed sleeve 350, thereby ensuring the realization of the counting function.

[0071] Please see Figure 1 and Figure 5 In one embodiment, the material includes a first workpiece and a second workpiece. The clamping structure 200 is provided with a clamping part at one end away from the mounting base 100. The clamping part is provided with a groove 211 and a contact surface 212 in sequence in the direction away from the mounting base 100. The groove 211 is used to engage with the periphery of the first workpiece, and the contact surface 212 is used to abut against the outer peripheral surface of the second workpiece.

[0072] In one embodiment, the first workpiece is a PCR plate cover 02, and the second workpiece is a PCR plate body 01. The gripping component can grip the PCR plate body 01 and move it to the experimental position. After the experiment is completed, the gripping component can grip the PCR plate cover 02 and move it above the PCR plate body 01 to seal the PCR plate body 01. After the PCR plate cover 02 and the PCR plate body 01 are combined, the gripping component can grip the combination of the PCR plate cover 02 and the PCR plate body 01 to the amplification module for interpretation of the experimental results.

[0073] The groove 211 is slightly larger in the Z-axis direction than the PCR plate cover 02, allowing the periphery of the PCR plate cover 02 to engage with the groove 211, ensuring the stability of the gripping component in gripping the PCR plate cover 02. The contact surface 212 is located on the side of the groove 211 furthest from the mounting base 100, and can abut against the outer peripheral surface of the PCR plate body 01, ensuring the stability of the gripping component in gripping the PCR plate body 01. Furthermore, the contact surface 212 has serrated protrusions to increase the friction between the contact surface 212 and the PCR plate body 01, preventing slippage when the gripper 210 grips the PCR plate body 01. Of course, in other embodiments, anti-slip pads or similar materials can be provided on the contact surface 212; this is not a limitation.
