Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and in no way limits the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0036] In order to solve the problems that the input material channel of the medical feeding device in the prior art usually only corresponds to one output channel, resulting in less material provided by the medical feeding device each time, greatly reducing the feeding efficiency of the medical feeding device, and being unable to ensure the economy of the medical feeding device, the present invention provides a medical feeding device and a design method for the medical feeding device. Among them, the design method is used to design the medical feeding device, and the medical feeding device is the medical feeding device described above and below, such as Figure 8The figure shows a flowchart of a design method for a medical feeding device. The design method includes the following steps: designing the pressing end of the calibration mechanism 20 so that the pressing end presses tightly on a part of the medical material 1 located in the pressing material channel 21 of the calibration mechanism 20; designing the picking end of the picking mechanism 30 so that the picking end picks up multiple medical materials 1 that are not pressed by the pressing end in the pressing material channel 21 at one time.

[0037] The design method includes the following steps:

[0038] Design multiple pressing ends, and arrange the multiple pressing ends at intervals. A picking space 100 for the picking end to pick up materials is formed between two adjacent pressing ends;

[0039] Design multiple picking ends, and arrange the multiple picking ends at intervals. Each picking end extends into the picking space 100 to pick up the medical material 1 in a state to be picked up located in the picking space 100.

[0040] The design method includes the following steps:

[0041] Design the number of pressing ends to be equal to the number of picking ends, and the sum of the number of pressing ends and the number of picking ends is equal to the pre-stored quantity of the medical material 1 in the pressing material channel 21;

[0042] Design the number of output channels to be equal to the number of picking ends, so that one picking end corresponds to one output channel.

[0043] As Figure 1 As shown, the medical feeding device includes a calibration mechanism 20 and a picking mechanism 30. Among them, the calibration mechanism 20 has a pressing material channel 21, and the pressing material channel 21 is used for placing the medical material 1 conveyed from the upstream; the picking mechanism 30 is arranged adjacent to the calibration mechanism 20, and the picking mechanism 30 has a picking end, and the picking end is used for picking up the medical material 1 located in the pressing material channel 21. Among them, the picking mechanism 30 can pick up multiple medical materials 1 at one time.

[0044] This application provides a medical feeding device with a calibration mechanism 20 and a picking mechanism 30, which not only ensures the feeding efficiency of the medical feeding device, but also avoids occupying a large space.

[0045] Specifically, by arranging the calibration mechanism 20 adjacent to the picking mechanism 30, in this way, when the medical material 1 conveyed from the upstream enters the pressing material channel 21, the medical material 1 can be temporarily stored, which provides convenience for the picking end of the subsequent picking mechanism 30 to pick up multiple medical materials 1 from the pressing material channel 21 at one time, thereby ensuring the picking reliability of the picking mechanism 30.

[0046] In addition, due to the compact structure of the above-mentioned medical feeding device, it avoids occupying a large space, and the above-mentioned medical feeding device has a simple structure, which is conducive to improving the economy of the medical feeding device.

[0047] It should be noted that in this application, the calibration mechanism 20 has a pressing end, and the pressing end is used to press a part of the medical material 1 located in the pressing material channel 21; the picking end is used to pick up the medical material 1 that is not pressed by the pressing end in the pressing material channel 21. In this way, by arranging the calibration mechanism 20 adjacent to the picking mechanism 30, when the medical material 1 conveyed upstream enters the pressing material channel 21, the pressing end of the calibration mechanism 20 presses a part of the medical material 1 located in the pressing material channel 21. On the one hand, it plays a role in accurately positioning each medical material 1, thereby minimizing the cumulative tolerance generated during the transportation of each medical material 1 as much as possible; on the other hand, the medical material 1 that is not pressed by the pressing end in the pressing material channel 21 is in a free state, so that when the picking end of the subsequent picking mechanism 30 picks up the medical material 1, other medical materials 1 will not interfere with the picking end, thereby ensuring the picking reliability of the picking mechanism 30.

[0048] As Figure 2 and Figure 3 shown, the medical materials 1 are placed in rows in the pressing material channel 21, there are multiple pressing ends, the multiple pressing ends are arranged at intervals, the multiple pressing ends have pressing positions for pressing the medical materials 1, and the multiple pressing ends have a first avoidance position away from the pressing material channel 21. A picking space 100 for the picking mechanism 30 is formed between two adjacent pressing ends. When all the multiple pressing ends are in the pressing positions, there is at least one medical material 1 between adjacent pressing ends in a state to be picked up. In this way, by setting the pressing ends in a structure including multiple ones, it is ensured that one pressing end corresponds to pressing one medical material 1, thereby ensuring the accuracy of the positioning of the medical materials 1 in the pressing material channel 21; in addition, since a picking space 100 for the picking mechanism 30 is formed between two adjacent pressing ends, it is ensured that the picking end of the picking mechanism 30 will not interfere with other medical materials 1 or the pressing ends.

[0049] It should be noted that in this application, when the multiple pressing ends are in the pressing positions, the picking mechanism 30 can pick up the medical materials 1 in the state to be picked up. In this way, on the one hand, it ensures that each medical material 1 to be picked can be located at a predetermined position, thereby ensuring the picking reliability of the picking mechanism 30; on the other hand, it avoids the picking end of the picking mechanism 30 interfering with other medical materials 1 and affecting the picking operation of the picking mechanism 30.

[0050] As Figure 2 and Figure 3As shown, the calibration mechanism 20 includes a first base body 22 and a plurality of positioning units 24. A positioning base 23 is provided on the first base body 22, and the positioning base 23 has a plurality of mounting grooves 231; the plurality of positioning units 24 are provided in one-to-one correspondence with the plurality of mounting grooves 231. Each positioning unit 24 includes a connecting arm 241 and a pressing arm 242. Among them, the first end of the connecting arm 241 is arranged in the mounting groove 231, the second end of the connecting arm 241 extends out of the mounting groove 231, the first end of the pressing arm 242 is connected to the second end of the connecting arm 241, and the second end of the pressing arm 242 forms a material pressing end. The plurality of positioning units 24 are arranged at intervals, and a material taking space 100 is formed between two adjacent positioning units 24; among them, the positioning base 23 is arranged relative to the first base body 22 to be liftable, so as to drive each positioning unit 24 to be in a pressing position or a first avoiding position, and the material taking end of the material taking mechanism 30 moves into the material taking space 100 to take away the medical material 1 in the state to be taken away. In this way, the setting of the plurality of mounting grooves 231 ensures the mounting reliability of the plurality of positioning units 24.

[0051] As Figure 3 shown, the pressing arm 242 includes a pressing arm body 2421, an elastic element 2422 and a pressing head 2423. Among them, the first end of the pressing arm body 2421 is connected to the connecting arm 241, and the second end of the pressing arm body 2421 is arranged in the vertical direction; the elastic element 2422 is sleeved on the outer peripheral side of the pressing arm body 2421; the pressing head 2423 is connected to the second end of the pressing arm body 2421, and the cross-sectional area of the pressing head 2423 is larger than the cross-sectional area of the pressing arm body 2421 and smaller than the cross-sectional area of the medical material 1. In this way, the contact area between the pressing head 2423 of the pressing arm 242 and the medical material 1 is increased as much as possible, so as to ensure the pressing reliability of the pressing head 2423.

[0052] It should be noted that in the present application, the surface of the pressing head 2423 facing the medical material 1 is adapted to the contact surface of the medical material 1. For example, the surface of the pressing head 2423 facing the medical material 1 is a part of a spherical surface, which is beneficial to increasing the contact area between the pressing head 2423 and the medical material 1.

[0053] As Figure 3As shown in the figure, the calibration mechanism 20 further includes a limit plate 25. The limit plate 25 is connected to the first base body 22 and is arranged along the horizontal direction. The limit plate 25 is movably arranged relative to the first base body 22 in the horizontal direction. The limit plate 25 includes a first limit plate 251 and a second limit plate 252. A plurality of first limit notches 2511 are formed at the edge position of the first limit plate 251; the second limit plate 252 is arranged opposite to the first limit plate 251, and a second limit notch 2521 is formed at the position of the second limit plate 252 opposite to the first limit notch 2511; wherein, both the first limit plate 251 and the second limit plate 252 have a working position above the material pressing channel 21, and both the first limit plate 251 and the second limit plate 252 have a second avoidance position away from the material pressing channel 21. When the medical material 1 enters the material pressing channel 21, the first limit plate 251 and the second limit plate 252 move towards the direction close to the material pressing channel 21 to the working position, and the first limit notch 2511 and the correspondingly second limit notch 2521 enclose an avoidance notch for avoiding the pressing arm 242. In this way, when the medical material 1 enters the material pressing channel 21, the first limit plate 251 and the second limit plate 252 are in the working position, playing a role of stopping and limiting the medical material 1 in the material pressing channel 21 and preventing the medical material 1 from falling off from the material pressing channel 21.

[0054] Specifically, when the quantity of the medical material 1 stored in the material pressing channel 21 reaches the preset quantity, each positioning unit 24 moves downward so that each material pressing end presses the medical material 1, and the first limit plate 251 and the second limit plate 252 move towards the direction away from the material pressing channel 21 to the second avoidance position. In this way, the pressing arm 242 of each positioning unit 24 passes through the avoidance notch and then presses the medical material 1, ensuring the pressing reliability of the pressing arm 242.

[0055] It should be noted that in the present application, the cross-sectional area of the avoidance notch is larger than the cross-sectional area of the pressing head 2423 and smaller than the cross-sectional area of the medical material 1. In this way, after the picking end of the picking mechanism 30 picks up the medical material 1 to be picked, the first limit plate 251 and the second limit plate 252 are switched from the second avoidance position to the working position, ensuring that the notch peripheries of the first limit notch 2511 on the first limit plate 251 and the second limit notch 2521 on the second limit plate 252 play a role of stopping and limiting the medical material 1 and preventing the material pressing end of the calibration mechanism 20 from driving the medical material 1 to move during the lifting process.

[0056] Such as Figure 4 and Figure 5As shown in the figure, the material taking mechanism 30 includes a second base body 31 and a plurality of material taking units 33. An installation beam 32 is arranged on the second base body 31. The plurality of material taking units 33 are arranged on the installation beam 32 at intervals. The first end of each material taking unit 33 is connected to the installation beam 32, and the second end of each material taking unit 33 forms a material taking end. The plurality of material taking ends have a material taking position extending into the material taking space 100, and the plurality of material taking ends have an exiting position exiting the material taking space 100. Wherein, the installation beam 32 can move relative to the second base body 31 in a direction close to the material taking space 100 to drive each material taking unit 33 to be in the material taking position, and the installation beam 32 can move relative to the second base body 31 in a direction away from the material taking space 100 to drive each material taking unit 33 to be in the exiting position. In this way, the reliability of the material taking operation of the plurality of material taking units 33 of the material taking mechanism 30 is ensured.

[0057] It should be noted that in the present application, the installation beam 32 is arranged relative to the second base body 31 so as to be liftable, to drive each material taking unit 33 to be in the material taking position or the exiting position. In this way, it is ensured that the installation beam 32 can drive each material taking unit 33 to move downward to pick up the medical material 1 to be picked up, and at the same time ensure that the installation beam 32 can drive each material taking unit 33 to move upward to exit the material taking space 100 and transfer the medical material 1 to the next process.

[0058] It should be noted that in the present application, the number of the positioning units 24 is equal to the number of the material taking units 33, and the sum of the number of the positioning units 24 and the number of the material taking units 33 is equal to the pre-stock quantity of the medical material 1 in the pressing material channel 21. In this way, the medical feeding device feeds in a staggered feeding manner, greatly improving the feeding efficiency of the medical feeding device.

[0059] It should be noted that in the present application, the number of the positioning units 24 is 12, the number of the material taking units 33 is 12, and the pre-stock quantity of the medical material 1 in the pressing material channel 21 is 24.

[0060] Optionally, the medical feeding device provided in the present application includes two calibration mechanisms 20 and two material taking mechanisms 30, and the two calibration mechanisms 20 and the two material taking mechanisms 30 are both symmetrically arranged. In this way, it is ensured that the medical feeding device can provide 24 medical materials 1 at a time, thus greatly improving the feeding efficiency of the medical feeding device.

[0061] Optionally, according to the feeding quantity of the required medical material 1, the number of the calibration mechanisms 20 and the material taking mechanisms 30 can be appropriately adjusted. At the same time, the number of the positioning units 24 of each calibration mechanism 20 and the number of the material taking units 33 of the material taking mechanism 30 can also be appropriately adjusted.

[0062] Such as Figure 1As shown, the medical feeding device further includes a feeding mechanism 10 and a material selection mechanism 40. Among them, the feeding mechanism 10 has an input material channel 11. The calibration mechanism 20 is arranged downstream of the feeding mechanism 10, and the pressing material channel 21 is communicated with the input material channel 11. The material selection mechanism 40 is arranged upstream of the feeding mechanism 10, and the material selection mechanism 40 has a discharge channel 41 communicated with the input material channel 11. Among them, the feeding mechanism 10 is a linear vibrating feeder, and the material selection mechanism 40 is a vibrating screen. In this way, the intelligent level of the medical feeding device is improved, which is beneficial to reducing labor force. In addition, the conveying reliability of the medical material 1 can be ensured.

[0063] It should be noted that in this application, the material taking mechanism 30 further includes a plurality of output material channels, and the plurality of output material channels are arranged in one-to-one correspondence with the plurality of material taking units 33. In this way, it is ensured that one output material channel corresponds to one medical material 1, thereby guaranteeing the feeding reliability of the medical feeding device, and enabling the medical feeding device provided in this application to realize one input material channel 11 corresponding to a plurality of output material channels.

[0064] It should be noted that in this application, the number of output material channels is 24.

[0065] Optionally, the medical material 1 is a blood collection needle connector.

[0066] As Figure 6 and Figure 7 shown, a guide rail 42 is arranged inside the discharge channel 41 of the material selection mechanism 40. The outer peripheral side of the medical material 1 has a hook structure, and the medical material 1 is hung on the guide rail 42 through the hook structure. While ensuring the conveying reliability of the medical material 1, it can also prevent the medical material 1 from jamming or reverse feeding in the discharge channel 41.

[0067] It should be noted that in this application, the material taking mode of the material taking unit 33 of the material taking mechanism 30 can be in the form of sucking materials, directly grasping, etc.

[0068] It should be noted that the terms used here are only for describing specific embodiments, rather than intending to limit the exemplary embodiments according to this application. As used here, unless the context clearly indicates otherwise, the singular form is also intended to include the plural form. In addition, it should also be understood that when the terms "comprising" and / or "including" are used in this specification, it indicates the presence of features, steps, operations, devices, components, and / or their combinations.

[0069] Unless otherwise specifically stated, the relative arrangements, numerical expressions, and numerical values of the components and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn in actual proportional relationships. Technologies, methods, and devices known to those of ordinary skill in the relevant art may not be discussed in detail, but where appropriate, the said technologies, methods, and devices should be regarded as part of the authorized specification. In all the examples shown and discussed here, any specific values should be construed as merely exemplary and not as a limitation. Thus, other examples of the exemplary embodiments may have different values. It should be noted that: like reference numerals and letters denote like items in the following drawings, and thus, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0070] For ease of description, spatial relative terms such as "above", "over", "on the upper surface", "upper", etc. may be used here to describe the spatial positional relationship of one device or feature to other devices or features as shown in the figures. It should be understood that the spatial relative terms are intended to encompass different orientations in use or operation in addition to the orientation depicted in the figures for the device. For example, if the device in the figure is inverted, the device described as "above" or "over" other devices or structures will then be positioned "below" or "beneath" other devices or structures.
