Description

Technical Field

[0001] This application relates to the field of medicinal material component extraction technology, and more specifically, to a capping mechanism and a visual inspection device. Background Technology

[0002] The extraction and separation of medicinal components mainly relies on manual processing, which is complex, tedious, and difficult to control in terms of dosage accuracy. Customized extraction equipment can replace manual labor, ensuring the consistency of experiments. Current automated extraction equipment can achieve automated extraction of trace amounts of medicinal materials; the specific process includes the entire process of extracting and separating medicinal components, including adding extractant, acid-base adjustment, heating and shaking, centrifugation and layering, filtration extraction, reconstitution and collection.

[0003] Currently, after the medicinal herb solution undergoes layering, a visual inspection component is needed to photograph the side of the bottle to identify the position of each layer, facilitating the extraction of the corresponding components. The bottle containing the medicinal herb solution needs to be moved from the limiting component to the position of the visual inspection component. Since the limiting component obstructs the bottle, it needs to be perforated. However, the perforation range of the limiting component is limited, which can easily interfere with visual recognition.

[0004] Therefore, how to avoid the influence of the limiting component on the image capture of the vision inspection component is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] In view of this, the purpose of this application is to provide a cap screwing mechanism to avoid the influence of the limiting component on the image capture of the vision detection component;

[0006] Another objective of this application is to provide a visual inspection device having the aforementioned cap-tightening mechanism.

[0007] To achieve the above objectives, this application provides the following technical solution:

[0008] The first aspect of this application provides a cap screwing mechanism, comprising:

[0009] A limiting component is used to secure the bottle to be capped.

[0010] A screw cap assembly is used to screw caps onto the bottle body on the limiting assembly.

[0011] The lifting component includes a lifting device and a first clamping device disposed at the output end of the lifting device. The first clamping device is used to clamp the target position of the bottle. The lifting device is used to lift the bottle to a designated position through the first clamping device. The designated position is a position that enables the vision detection component to acquire a detection image of the position to be captured on the bottle.

[0012] In one possible implementation, the first clamping device includes a first clamping drive device and two first grippers for clamping the bottle at a target position;

[0013] The first clamping drive device includes two first output sections that move synchronously in opposite directions, and the two first grippers are respectively connected to the two first output sections.

[0014] In one possible implementation, the first gripper is provided with a first arc-shaped slot, which is configured to engage with a target position of the bottle.

[0015] In one possible implementation, the first arc-shaped slot is configured to engage with the bottle opening position of the bottle body, the target position of the bottle body being the bottle opening position.

[0016] In one possible implementation, the limiting component includes a receiving device and a second clamping device, the receiving device being located below the second clamping device;

[0017] The receiving device is used to position the bottle body, and the second clamping device is used to clamp and fix the bottle body and cooperate with the screw cap assembly to realize the screw cap operation on the bottle body.

[0018] In one possible implementation, the receiving device has a receiving groove that matches the outer contour of the bottle body, and the clamping part of the second clamping device is located above the receiving groove.

[0019] In one possible implementation, the second clamping device includes a second clamping drive and two second grippers for clamping the bottle body;

[0020] The second clamping drive device includes two second output sections that move synchronously in opposite directions, and two second grippers are respectively connected to the two second output sections.

[0021] In one possible implementation, the second gripper includes a gripper arm and a clamping portion disposed on the gripper arm. The gripper arm is connected to the second output portion, and the clamping portion is provided with a second arc-shaped slot, which is configured to cooperate with the bottle body.

[0022] In one possible implementation, a buffer layer is provided inside the second arc-shaped slot.

[0023] The capping mechanism provided in this application uses a limiting component to fix the bottle body, ensuring that the bottle body does not rotate when the capping component turns the cap, thus completing the capping operation and facilitating subsequent extraction of the corresponding components. During image capture and inspection using a visual inspection component, a lifting component raises the bottle to a certain height to prevent the limiting component from obstructing the area to be sampled. This allows the visual inspection component to acquire a complete image of the area to be sampled, identifying the position of each layer of components within the bottle. The extraction unit of the extraction component can then move to the appropriate height within the bottle to extract the corresponding component solution. The capping mechanism provided in this application incorporates a lifting component, which raises the bottle to a certain height when visual inspection is required, avoiding the influence of the limiting component on visual inspection and improving the accuracy of the inspection.

[0024] A second aspect of this application provides a visual inspection device, comprising:

[0025] Visual inspection components;

[0026] The screw cap mechanism as described in any of the preceding items

[0027] A linear module is provided, wherein the limiting component and the lifting component of the capping mechanism are disposed at the output end of the linear module, and the linear module is used to drive the limiting component and the lifting component to move between the capping position and the detection position. The capping component of the capping mechanism is disposed at the capping position, and the vision detection component is disposed at the detection position to obtain a detection image of the bottle that has moved to the detection position.

[0028] The visual inspection component provided in this application has the aforementioned cap-tightening mechanism, and therefore possesses all the technical effects of the aforementioned cap-tightening mechanism, which will not be elaborated upon here. Attached Figure Description

[0042] This application discloses a screw-on mechanism to avoid the influence of the limiting component on the image capture of the vision detection component;

[0043] This application also discloses a visual inspection device having the above-described cap-tightening mechanism.

[0044] Hereinafter, embodiments will be described with reference to the accompanying drawings. Furthermore, the embodiments shown below do not limit the scope of the application as described in the claims. Additionally, the complete composition represented in the embodiments below is not limited to what is necessary as the solution to the application described in the claims. It should be noted that, for ease of description, only the parts relevant to the application are shown in the drawings. Unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0045] like Figure 1 As shown in the figure, this application discloses a screw cap mechanism for screwing caps onto a bottle to facilitate the extraction of the corresponding components after layering by the extraction component.

[0046] The capping mechanism disclosed in this application includes a limiting component, a capping component, and a lifting component. The limiting component is used to fix the bottle 180 to be capped. The method by which the limiting component fixes the bottle 180 is not limited, as long as it can restrict the rotation of the bottle 180 during capping. The bottle 180 fixed by the limiting component is a bottle 180 that has undergone a layering process. After the component solution in the bottle 180 has undergone the layering process, different components are located at different heights in the bottle 180. Therefore, by drawing the solution from different heights, the component at the corresponding height can be obtained.

[0047] The capping assembly (not shown in the figure) is used to cap the bottle 180 on the limiting assembly, so that the bottle mouth of the bottle 180 is in an open state, so that the extraction part of the extraction assembly can be inserted into the bottle through the bottle mouth of the bottle 180 to draw the corresponding height of the component.

[0048] The lifting assembly includes a lifting device 150 and a first clamping device disposed at the output end of the lifting device 150. The first clamping device is used to clamp the bottle body 180 at a target position. The lifting device 150 is used to lift the bottle body 180 to a designated position through the first clamping device. The designated position is a position that allows the vision detection component (generally a vision camera) to acquire a detection image of the position to be captured on the bottle body 180. The lifting device 150 can be any device that can output linear displacement, such as a lifting cylinder, hydraulic cylinder, or linear motor. This embodiment does not limit the specific type of the lifting device 150.

[0049] The lifting component is used when visual acquisition is required. When visual image acquisition is required, the target position of the bottle 180 is first clamped by the first clamping device, and then the lifting device 150 drives the first clamping device to rise, thereby raising the bottle 180, so that the position to be acquired on the bottle 180 is not blocked by the limiting component, and the visual detection component can acquire the image of the position to be acquired on the bottle 180.

[0050] Because the different components in each layer of the bottle are different, their colors vary. After the visual inspection component acquires the image, it can identify the boundary position of each layer of components through color differences, and then obtain the height of each layer of components.

[0051] The capping mechanism disclosed in this application uses a limiting component to fix the bottle 180, ensuring that the bottle body does not rotate when the capping component rotates, thus completing the capping operation and enabling subsequent extraction of the corresponding components. During image capture by a visual inspection component, a lifting component raises the bottle 180 to a certain height to prevent the limiting component from obstructing the image of the area to be captured. This allows the visual inspection component to acquire a complete image of the area to be captured, identifying the positions of the components within the bottle 180. This allows the extraction unit of the extraction component to move to the corresponding height within the bottle 180 to extract the corresponding component solution. The capping mechanism provided in this application adds a lifting component, which can raise the bottle 180 to a certain height when visual inspection is required, avoiding the influence of the limiting component on visual inspection and improving the accuracy of the inspection.

[0052] After the lifting assembly raises the bottle 180 to a certain height, the vision inspection assembly can take a picture of the unobstructed bottle 180 from the corresponding position, obtaining a clearer and more complete image, providing a reliable basis for subsequent accurate measurements. After obtaining accurate height and position information of each layer of components through the vision inspection assembly, the control system can calculate the depth that the extraction part of the extraction assembly (such as a pipette) needs to penetrate, avoiding extraction errors (such as inserting it to the bottom of the bottle or extracting the wrong layer).

[0053] like Figure 3 As shown in a specific embodiment of this application, the first clamping device includes a first clamping drive device 160 and two first grippers 170 for clamping the bottle body 180 at a target position. The first clamping drive device 160 includes two first output sections 161 that move synchronously in opposite directions, and the two first grippers 170 are respectively connected to the two first output sections 161. Specifically, the first grippers 170 can be fixed to the first output sections 161 by fasteners so that they can be replaced after wear.

[0054] The first clamping drive device 160 can be a clamping cylinder, with its two first output parts 161 moving synchronously in opposite directions. For example, when the two first output parts 161 move toward each other, the clamping action of the two first grippers 170 can be realized; when the two first output parts 161 move toward each other, the releasing action of the two first grippers 170 can be realized.

[0055] To facilitate the first gripper 170 clamping the bottle 180 at the target position, in this embodiment, the first gripper 170 is provided with a first arc-shaped groove 171, which is configured to engage with the target position of the bottle 180. In this embodiment, by providing the first arc-shaped groove 171 on the first gripper 170 to engage with the target position of the bottle 180, the contact area between the first gripper 170 and the bottle 180 can be increased. Under the same pressure exerted by the first gripper 170 on the bottle 180, the frictional force between the first gripper 170 and the bottle 180 can be increased, thereby ensuring the stability of the first gripper 170 in clamping the bottle 180.

[0056] The target position of the bottle body 180 is the bottle opening (which can be the bottle opening after the cap is unscrewed, or the bottle opening with the cap on; when the cap is on, the first gripper 170 holds the cap). That is, the first arc-shaped groove 171 is configured to engage with the bottle opening of the bottle body 180. Taking the bottle opening after the cap is unscrewed as an example, the bottle opening has external threads that engage with the cap, thus generating greater friction and maintaining gripping stability. In this embodiment, the first gripper 170 holding the bottle opening of the bottle body 180 also avoids obstructing the bottle body, preventing the first gripper 170 from affecting visual inspection and improving inspection accuracy.

[0057] In one specific embodiment of this application, the lifting component is located on one side of the limiting component, that is, the lifting component is not located above the limiting component. The lifting component is located on the side of the limiting component and lifts the bottle 180 positioned by the limiting component to reduce the space occupied above the limiting component.

[0058] In this embodiment, the limiting component may include a receiving device 120 and a second clamping device. The receiving device 120 is located below the second clamping device. The receiving device 120 is used to position the bottle 180, and the second clamping device is used to clamp and fix the bottle 180, and cooperates with the capping assembly to realize the capping operation of the bottle 180. After the layering process is completed, the bottle 180 is transferred to the receiving device 120 and initially positioned by the receiving device 120. Then, the second clamping device clamps and fixes the bottle 180 above the receiving device 120. That is, the receiving device 120 is used to position the lower part of the bottle 180, while the second clamping device is used to fix the upper part of the bottle 180. This can ensure the stability of the bottle 180, so that when the cap is turned, the bottle 180 does not rotate with it, increasing the success rate of capping.

[0059] Furthermore, the receiving device 120 is provided with a receiving groove that matches the outer contour of the bottle body 180, and the clamping part 142 of the second clamping device is located above the receiving groove. The diameter of the receiving groove of the receiving device 120 may be slightly larger than the outer diameter of the bottle body 180 to facilitate the insertion of the bottom of the bottle body 180 into the receiving groove of the receiving device 120.

[0060] The depth of the receiving groove of the receiving device 120 can be designed by those skilled in the art based on the height of the bottle 180, as long as it can ensure that the bottle 180 can be positioned after being placed in the receiving groove to prevent the bottle 180 from tilting or falling over.

[0061] Furthermore, such as Figure 1 and Figure 2As shown, the second clamping device may include a second clamping drive device 130 and two second grippers 140 for clamping the bottle body 180. The second clamping drive device 130 includes two second output sections that move synchronously in opposite directions, and the two second grippers 140 are respectively connected to the two second output sections. Specifically, the second grippers 140 can be fixed to the second output sections by fasteners so that they can be replaced after wear.

[0062] The second clamping drive device 130 can be a clamping cylinder, whose two second output parts move synchronously in opposite directions. For example, when the two second output parts move towards each other, the clamping action of the two second grippers 140 can be realized; when the two second output parts move away from each other, the releasing action of the two second grippers 140 can be realized.

[0063] The movement direction of the second gripper 140 can be perpendicular to the shooting direction of the vision detection component, so that the vision detection component is located in the area between the two second grippers 140. When it is necessary to acquire a visual image, the lifting device 150 raises the bottle 180 above the receiving device 120, and the second clamping drive device 130 controls the second grippers 140 to open, allowing the vision detection component to take a picture. This configuration can reduce the height of the bottle 180 during shooting, thus reducing the space occupied above the bottle 180.

[0064] Furthermore, the second gripper 140 includes a gripper arm 141 and a gripping portion 142 disposed on the gripper arm 141, the gripper arm 141 being connected to the second output portion. Specifically, the gripper arm 141 can be fixed to the second output portion by fasteners, so that it can be replaced after wear. Correspondingly, the gripping portion 142 can be fixed to the gripper arm 141 by fasteners, so that it can be replaced after wear.

[0065] The clamping part 142 is provided with a second arc-shaped groove 1421, which is configured to cooperate with the bottle body 180. In this embodiment, by providing a second arc-shaped groove 1421 on the clamping part 142 to cooperate with the bottle body 180, the contact area between the clamping part 142 and the bottle body 180 can be increased. Under the same pressure exerted by the clamping part 142 on the bottle body 180, the friction between the clamping part 142 and the bottle body 180 can be increased, thereby ensuring the stability of the clamping part 142 in clamping the bottle body 180.

[0066] Because the second gripper 140 requires a large clamping force to hold the bottle 180, it is necessary to ensure that the bottle body 180 does not rotate when the cap is screwed on. However, the bottle body 180 is usually made of plastic or glass, and a large clamping force can easily cause the bottle body 180 to be deformed or broken.

[0067] Based on this, in a specific embodiment of this application, a buffer layer is provided inside the second arc-shaped slot 1421. The material of the buffer layer can be rubber, silicone, etc. When the second gripper 140 grips the bottle body 180, the part in contact with the bottle body 180 is the buffer layer. The buffer layer has a certain buffering function, which can reduce damage to the bottle body. In addition, the friction between the buffer layer and the bottle body is greater, thus reducing the clamping force required and ensuring that the bottle body 180 does not rotate when the cap is screwed on.

[0068] It should be noted that the clamping part 142 and the gripper arm 141 can also be designed to be made of different materials. For example, the gripper arm 141 can be made of a high-strength metal, while the clamping part 142 can be designed to be made of rubber or silicone, which has greater elasticity and a higher coefficient of friction. In this way, even without a buffer layer in the second arc-shaped groove 1421, the friction between the clamping part 142 and the bottle body can still be increased, thus reducing the clamping force required and ensuring that the bottle body 180 does not rotate when the cap is screwed on.

[0069] This application also discloses a visual inspection device, which includes a visual inspection component, a cap screwing mechanism, and a linear module.

[0070] The cap screwing mechanism is the same as the cap screwing mechanism disclosed in the above embodiment. The visual inspection device disclosed in this application embodiment has the above-mentioned cap screwing mechanism, and therefore has all the technical effects of the above-mentioned cap screwing mechanism. It will not be described again here.

[0071] The limiting component and lifting component of the cap-screwing mechanism are located at the output end of the linear module. To facilitate the connection between the limiting component and lifting component of the cap-screwing mechanism and the output end of the linear module, the cap-screwing mechanism may also include a base 110. The limiting component and lifting component can be fixed on the base 110, and then the base 110 can be fixed to the output end of the linear module, thereby realizing the connection between the limiting component and lifting component and the output end of the linear module.

[0072] The linear module is used to move the limiting component and the lifting component between the capping position and the detection position. Since the bottle 180 is in different positions during capping and detection, a linear module is needed to change the positions of the limiting component and the lifting component. The capping component of the capping mechanism is located at the capping position, and the vision detection component is located at the detection position to acquire a detection image of the bottle 180 as it moves to the detection position.

[0073] When the bottle 180 needs to be capped, the linear module can move the bottle 180 on the limiting component to the capping position, so that the capping component located at the capping position can perform the capping operation on the bottle 180 on the limiting component; when the bottle 180 needs to be image acquired, the linear module can move the bottle 180 on the limiting component to the detection position, so that the vision detection component located at the detection position can acquire the image of the bottle 180 on the limiting component.
