Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device assembly technology, specifically to a needle assembly mechanism. Background Technology
[0002] In the field of medical devices, the use of acupuncture needles in conjunction with plastic tubing is very common. The plastic tubing is placed over the outside of the acupuncture needle, ensuring that the needle handle is exposed. This design aims to protect the needle body while facilitating the doctor's operation.
[0003] Currently, the assembly of plastic tubes and acupuncture needles is mostly carried out in specific grooves. After the plastic tubes are placed in the grooves, their positions deviate from each other. Specifically, the ends of the plastic tubes are often not parallel, resulting in inconsistent assembly with the corresponding acupuncture needles. This manifests as differences in the position of the acupuncture needles within the plastic tubes; for example, the handle of some acupuncture needles may be inside the plastic tube, leading to inconsistent assembly quality.
[0004] Furthermore, during assembly within the tank, the acupuncture needles and plastic tubes are prone to upward movement due to various external forces. Once they move upward, they will detach from their intended assembly positions, making assembly impossible. This not only reduces production efficiency but also increases production costs.
[0005] Therefore, how to overcome the shortcomings of the existing technology mentioned above has become the subject of this utility model. Utility Model Content
[0006] The purpose of this invention is to provide a needle assembly mechanism.
[0007] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0008] A needle assembly mechanism, characterized in that it comprises:
[0009] The transfer assembly, as a mechanism for synchronously transporting acupuncture needles and plastic tubes, has a plurality of positioning slots for positioning the acupuncture needles and plastic tubes; each of the positioning slots is parallel to each other and evenly arranged along a first predetermined path.
[0010] A plastic tube alignment assembly is disposed on one side of the transfer assembly and serves as a mechanism for aligning the plastic tubes.
[0011] A positioning component is disposed above the transfer component, serving as a mechanism to prevent the acupuncture needle from separating from the positioning groove during the assembly process;
[0012] A blow needle assembly, disposed on one side of the transfer assembly, serves as a mechanism for moving the acupuncture needle to assemble it with the plastic tube.
[0013] In some embodiments, the length direction of the positioning groove is perpendicular to the material conveying direction.
[0014] In some embodiments, the plastic tube alignment assembly is disposed on one side of the transfer assembly in a direction perpendicular to the material conveying direction.
[0015] In some implementations, the first predetermined path is a circular path, which can be referenced to the running path of the belt in a belt conveyor.
[0016] In the above scheme, during assembly, the acupuncture needle and the plastic tube are placed in the positioning groove. The positioning groove moves the acupuncture needle and the plastic tube along the first predetermined path. After the plastic tube enters the alignment area, the plastic tube alignment component causes each plastic tube to align. After the plastic tube enters the positioning area, the positioning component moves closer to the transfer component to limit the separation of the acupuncture needle and the plastic tube from the positioning groove during the assembly process. Then, the blow needle component causes the acupuncture needle to move to assemble with the plastic tube.
[0017] It should be noted that the above operating process can be adapted in practice. For example, when the needle blowing assembly is running, the transfer assembly can continue to run or stop running depending on the actual situation. Another example is that the positioning assembly can remain in this position after it moves closer to the transfer assembly.
[0018] It should also be noted that the material conveying direction in this application can be understood as the horizontal direction.
[0019] This application combines a transfer assembly, a plastic tube alignment assembly, a positioning assembly, and a blow needle assembly. During the transfer assembly's transport of the acupuncture needle and the plastic tube, the plastic tube alignment assembly moves the plastic tube into a predetermined area for alignment, preventing the inconsistent position of the plastic tube from affecting the subsequent assembly effect. At the same time, the positioning assembly works with the plastic tube alignment assembly to position the acupuncture needle and the plastic tube, further ensuring the assembly effect by preventing the acupuncture needle and the plastic tube from separating from the positioning groove during the assembly process.
[0020] In summary, this application, through the combination of the above structures, ensures production efficiency and finished product qualification rate, and avoids increasing additional production costs.
[0021] It should be emphasized that the structural support is a conventional setting, and the position of the structure can be adjusted according to the actual situation. Taking the plastic pipe alignment component as an example, the plastic pipe alignment component can be connected to the transfer component, and the transfer component supports the plastic pipe alignment component. Alternatively, a separate structure can be set to support the plastic pipe alignment component. A portion of the plastic pipe alignment component can be set above the transfer component, and the entire plastic pipe alignment component can also be set horizontally to the side of the transfer component.
[0022] In a further technical solution, the transfer assembly includes a drive mechanism, a conveyor belt, and several positioning plates connected in sequence;
[0023] The drive mechanism serves as a component for driving the conveyor belt to move cyclically along the first predetermined path;
[0024] Each of the positioning plates is sequentially fixed and attached to the surface of the conveyor belt along the first predetermined path;
[0025] Each of the aforementioned positioning plates is provided with at least one of the aforementioned positioning grooves.
[0026] The positioning plate is designed to accommodate the assembly of acupuncture needles and plastic tubes of different specifications. When in use, the positioning slot is compatible with the acupuncture needles and plastic tubes. When replacing acupuncture needles and plastic tubes of other specifications, only the positioning plate needs to be replaced.
[0027] In some embodiments, the positioning plate consists of a base structure and a plate-like structure. The base structure is fixed to the surface of the conveyor belt, and the plate-like structure is connected to the base structure. Positioning grooves are provided on the plate-like structure. When each plate-like structure moves in the horizontal direction, adjacent plate-like structures fit together. When the plate-like structures enter an arc-shaped path, they separate.
[0028] In a further technical solution, the bottom wall of the positioning groove is set as an arc surface;
[0029] And / or, at least a portion of the sidewall of the positioning groove is a vertical surface.
[0030] When the bottom wall of the positioning groove is set to be curved, taking an acupuncture needle as an example, the acupuncture needle will automatically align itself after entering the positioning groove, and accurately stop in the predetermined area. At this time, the size of the positioning groove can be slightly larger than the size of the acupuncture needle, so that the acupuncture needle can enter the predetermined area in the positioning groove without obstruction.
[0031] In a further technical solution, the positioning groove includes a first section for accommodating acupuncture needles and a second section for accommodating plastic tubes, wherein the longitudinal cross-sectional dimension of the first section is smaller than that of the second section.
[0032] For ease of understanding and explanation, the longitudinal sections of both the first and second segments are set to be circular, with the diameter of the first segment being half the diameter of the second segment. This allows the acupuncture needle to be inserted directly into the inside of the plastic tube without being obstructed by the end face of the plastic tube.
[0033] In some embodiments, the first segment and the second segment are coaxially arranged, which is suitable for situations where the first segment and the second segment are respectively adapted to the acupuncture needle and the plastic tube.
[0034] A single positioning slot can accommodate both acupuncture needles and plastic tubes simultaneously. In this case, only a single drive structure is needed to drive the positioning slot. That is, the acupuncture needles and plastic tubes are transported by the same conveying device, avoiding the need to set up two conveying devices and also avoiding the need to achieve precise synchronous operation of the two conveying devices.
[0035] In a further technical solution, the top surface of the positioning plate includes at least one inclined or curved surface for guiding the acupuncture needle and the plastic tube into the positioning groove.
[0036] The following explanation uses an inclined plane.
[0037] For ease of understanding and explanation, the positioning plate is set with only a single positioning slot, and the top surface of the positioning plate has two inclined surfaces. The two inclined surfaces are symmetrically arranged on both sides of the opening of the positioning slot to form an inverted V-shape. During operation, taking an acupuncture needle as an example, the acupuncture needle may fall directly into the positioning slot, or it may fall into the inclined surface first and then be guided into the positioning slot.
[0038] By setting the inclined plane, the probability of the acupuncture needle and the plastic tube entering the positioning groove can be increased, and the requirements for the matching accuracy of each driving structure in this application can be reduced.
[0039] In some embodiments, the top of the positioning plate is provided with one or more staggered teeth. The staggered teeth may be integrated with the positioning plate or considered as part of the positioning plate. The top surface of the staggered teeth is a sloped or curved surface. The staggered teeth are located at the edge of the positioning plate, mainly to prevent acupuncture needles from falling between the two positioning plates. In some embodiments, the top surface of the staggered teeth is considered as part of the top surface of the positioning plate.
[0040] In a further technical solution, the plastic tube alignment assembly includes a drive component and a push plate connected to each other;
[0041] The driving component serves as a part for driving the push plate to move along the length direction of the positioning groove;
[0042] Along the length of the positioning groove, at least a portion of the projection of the positioning groove coincides with the projection of the push plate.
[0043] Through the push plate as an intermediate structure, the driving component drives the plastic tube to move along the length of the positioning groove to achieve alignment of each plastic tube, thus avoiding inconsistent assembly results with the acupuncture needle due to different plastic tube positions.
[0044] It should be noted that in some cases, after the acupuncture needles are assembled with the plastic tube, the plastic tube still needs to be assembled with the insert. Before the insert is assembled with the plastic tube, the acupuncture needles are prone to relative movement with the plastic tube. Therefore, some embodiments also include a needle handle alignment assembly, which is used to align the handles of each acupuncture needle before the insert is assembled with the plastic tube. The specific configuration of the needle handle alignment assembly can refer to that of the plastic tube alignment assembly, as long as it meets the above requirements; no specific limitations are made here.
[0045] As for the push plate, on the one hand, it can realize the alignment of the plastic tube into the predetermined area, so as to avoid the relative position of the acupuncture needle and the plastic tube not being as expected. On the other hand, it can restrict the plastic tube and the acupuncture needle in the length direction of the positioning groove, such as preventing the acupuncture needle from completely passing through the plastic tube in case of accident (such as when a large force is applied to the acupuncture needle).
[0046] In a further technical solution, the positioning component includes a driver and a positioning element connected together;
[0047] The actuator serves as a component for vertically driving the positioning element to move.
[0048] The positioning element serves as a component used to prevent the acupuncture needle from separating from the positioning groove during the assembly process of the plastic tube.
[0049] Without considering the positioning groove's effect on the acupuncture needle and the plastic tube, during the assembly process, the acupuncture needle moves along the length of the positioning groove and needs to be restricted in directions other than this direction, while the plastic tube needs to remain stationary. Therefore, the positioning component does not have the same effect on the two.
[0050] Before assembling the acupuncture needle and the plastic tube, the driver moves the positioning component downward so that the positioning component covers at least part of the opening at the top of the positioning groove, thereby simultaneously preventing the acupuncture needle and the plastic tube from separating from the positioning groove during the assembly process, thus facilitating the assembly of the acupuncture needle and the plastic tube.
[0051] In a further technical solution, the blow-needle assembly includes at least one blowpipe for guiding gas towards the acupuncture needle.
[0052] It should be noted that the blowpipe only guides the gas, and the gas (or airflow or compressed gas) is generated by existing devices (such as blowers), which is well known to those skilled in the art and is not specifically limited here.
[0053] In a further technical solution, the blowpipe has an air outlet that is inclined toward the transfer assembly.
[0054] The tilt angle of the air outlet can be 45 degrees, and there is no specific limitation here.
[0055] With the configuration of this embodiment, even if the air outlet does not penetrate deep into the positioning groove, the gas can still be guided to blow the acupuncture needle, avoiding the blowpipe from affecting the movement of the positioning groove, and also avoiding the movement of the positioning groove from causing the blow needle assembly to move.
[0056] In a further technical solution, the longitudinal cross-sectional dimension of the air outlet is larger than the longitudinal cross-sectional dimension of the positioning groove.
[0057] To make it easier to understand, in the vertical direction, the length of the projection of the air outlet is greater than the length of the projection of the positioning groove, or in other words, the width of the air outlet is greater than the width of the positioning groove.
[0058] By setting up this embodiment, with a single air outlet guiding gas to a single positioning groove, even if the air outlet is not aligned with the positioning groove, it can avoid the air outlet failing to guide the gas to the positioning groove or having a poor guiding effect, ensuring that the acupuncture needle can move and connect to the plastic tube.

[0064] The working principle and advantages of this utility model are as follows:
[0065] During assembly, the acupuncture needle and the plastic tube are placed in the positioning groove. The positioning groove moves the acupuncture needle and the plastic tube along the first predetermined path. After the plastic tube enters the alignment area, the plastic tube alignment component causes each plastic tube to align. After the plastic tube enters the positioning area, the positioning component moves closer to the transfer component to prevent the acupuncture needle and the plastic tube from separating from the positioning groove during the assembly process. Then, the blow needle component causes the acupuncture needle to move to assemble with the plastic tube.
[0066] This application combines a transfer assembly, a plastic tube alignment assembly, a positioning assembly, and a blow needle assembly. During the transfer assembly's transport of the acupuncture needle and the plastic tube, the plastic tube alignment assembly moves the plastic tube into a predetermined area for alignment, preventing the inconsistent position of the plastic tube from affecting the subsequent assembly effect. At the same time, the positioning assembly works with the plastic tube alignment assembly to position the acupuncture needle and the plastic tube, further ensuring the assembly effect by preventing the acupuncture needle and the plastic tube from separating from the positioning groove during the assembly process.
[0067] In summary, this application, through the combination of the above structures, ensures production efficiency and finished product qualification rate during the plastic pipe assembly process, and avoids increasing additional production costs. Attached Figure Description

[0077] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0078] Example: The present invention will be clearly described below with illustrations and detailed description. Any person skilled in the art who understands the examples of the present invention can make changes and modifications based on the technology taught in the present invention without departing from the spirit and scope of the present invention.
[0079] The terminology used herein is for the purpose of describing specific embodiments only and is not intended to limit the scope of this work. Singular forms such as “a,” “this,” “this,” “the,” and “the” as used herein also include plural forms.
[0080] See Figures 1-8 A needle assembly mechanism, characterized in that it comprises:
[0081] The transfer assembly 1, as a mechanism for synchronously transporting acupuncture needles and plastic tubes, has a plurality of positioning grooves 11 for positioning acupuncture needles and plastic tubes; each of the positioning grooves 11 is parallel to each other and evenly arranged along a first predetermined path.
[0082] Plastic tube alignment component 2 is disposed on one side of the transfer component 1 and serves as a mechanism for aligning the plastic tubes.
[0083] Positioning component 3 is disposed above the transfer component 1 and serves as a mechanism to prevent the acupuncture needle from separating from the positioning groove 11 during the assembly process;
[0084] The blow needle assembly 4 is disposed on one side of the transfer assembly 1 and serves as a mechanism for moving the acupuncture needle to assemble with the plastic tube.
[0085] In some embodiments, the length direction of the positioning groove 11 is perpendicular to the material conveying direction.
[0086] In some embodiments, the plastic tube alignment assembly 2 is disposed on one side of the transfer assembly 1 in a direction perpendicular to the material conveying direction.
[0087] In some embodiments, the first predetermined path is a circular path, which can be referenced to the running path of the belt in a belt conveyor.
[0088] During assembly, the acupuncture needle and the plastic tube are placed in the positioning groove 11. The positioning groove 11 moves the acupuncture needle and the plastic tube along the first predetermined path. After the plastic tube enters the alignment area, the plastic tube alignment component 2 causes each plastic tube to align. After the plastic tube enters the positioning area, the positioning component 3 moves closer to the transfer component 1 to prevent the acupuncture needle and the plastic tube from separating from the positioning groove 11 during the assembly process. Then, the blow needle component 4 causes the acupuncture needle to move to assemble with the plastic tube.
[0089] It should be noted that the above operating process can be adapted in practice. For example, when the needle blowing assembly 4 is running, the transfer assembly 1 can continue to run or stop running according to the actual situation. Another example is that the positioning assembly 3 can stay in this position after it moves closer to the transfer assembly 1.
[0090] It should also be noted that the material conveying direction in this application can be understood as the horizontal direction.
[0091] This application combines a transfer assembly 1, a plastic tube alignment assembly 2, a positioning assembly 3, and a blow needle assembly 4. During the process of the transfer assembly 1 conveying the acupuncture needle and the plastic tube, the plastic tube alignment assembly 2 moves the plastic tube into a predetermined area for alignment, so as to avoid the subsequent assembly effect being affected by the inconsistent position of the plastic tube. At the same time, the positioning assembly 3 cooperates with the plastic tube alignment assembly 2 to position the acupuncture needle and the plastic tube, thereby preventing the acupuncture needle and the plastic tube from separating from the positioning groove 11 during the assembly process, so as to further ensure the assembly effect.
[0092] In summary, this application, through the combination of the above structures, ensures production efficiency and finished product qualification rate, and avoids increasing additional production costs.
[0093] It should be emphasized that the support of the structure is a conventional setting, and the position of the structure can be adjusted according to the actual situation. Taking the plastic pipe alignment component 2 as an example, the plastic pipe alignment component 2 can be connected to the transfer component 1, and the transfer component 1 supports the plastic pipe alignment component 2. A separate structure can also be set to support the plastic pipe alignment component 2. A part of the plastic pipe alignment component 2 can be set above the transfer component 1, and the entire plastic pipe alignment component 2 can also be set horizontally to the side of the transfer component 1.
[0094] See Figure 1 , Figure 8 In this embodiment, the transfer assembly 1 includes a drive mechanism 12, a conveyor belt 13 and a plurality of positioning plates 14 connected in sequence.
[0095] The drive mechanism 12 serves as a component for driving the conveyor belt 13 to move cyclically along the first predetermined path;
[0096] Each of the positioning plates 14 is sequentially fixed and attached to the surface of the conveyor belt 13 along the first predetermined path;
[0097] Each of the positioning plates 14 is provided with at least one positioning groove 11.
[0098] In some embodiments, the drive mechanism 12 and the conveyor belt 13 form a conventional single or two belt conveyors.
[0099] It should be noted that, taking the drive mechanism 12 as an example, it can adopt various existing devices for achieving the corresponding purpose. These are existing devices, and no specific restrictions are imposed here.
[0100] It should also be noted that, taking the drive mechanism 12 as an example, the support of the drive mechanism 12 is a conventional setting. Even if it is not explicitly stated, it should be known that some support columns or other structures can be set for support.
[0101] The positioning plate 14 is designed to accommodate the assembly of acupuncture needles and plastic tubes of different specifications. When in use, the positioning groove 11 is compatible with the acupuncture needles and plastic tubes. When replacing acupuncture needles and plastic tubes of other specifications, only the positioning plate 14 needs to be replaced.
[0102] In some embodiments, the positioning plate 14 consists of a base structure and a plate-like structure. The base structure is fixed to the surface of the conveyor belt 13, and the plate-like structure is connected to the base structure. The positioning groove 11 is provided on the plate-like structure. When each plate-like structure moves in the horizontal direction, adjacent plate-like structures fit together. When the plate-like structures enter the arc-shaped route, they separate.
[0103] See Figure 7 In this embodiment, the bottom wall of the positioning groove 11 is set as an arc surface;
[0104] And / or, at least a portion of the sidewall of the positioning groove 11 is a vertical surface.
[0105] When the bottom wall of the positioning groove 11 is set to be curved, taking an acupuncture needle as an example, the acupuncture needle will automatically align itself after entering the positioning groove 11, and accurately stop in the predetermined area. At this time, the size of the positioning groove 11 can be slightly larger than the size of the acupuncture needle, so that the acupuncture needle can enter the predetermined area in the positioning groove 11 without obstruction.
[0106] In some embodiments, at least a portion of the sidewall of the positioning groove 11 is a vertical surface to prevent the acupuncture needle from moving too much relative to the positioning groove 11 during its movement.
[0107] See Figure 6 , Figure 7 In this embodiment, the positioning groove 11 includes a first section 111 for accommodating acupuncture needles and a second section 112 for accommodating plastic tubes, wherein the longitudinal cross-sectional dimension of the first section 111 is smaller than the longitudinal cross-sectional dimension of the second section 112.
[0108] For ease of understanding and explanation, the longitudinal sections of both the first segment 111 and the second segment 112 are set to be circular. The diameter of the first segment 111 is half the diameter of the second segment 112, so that the acupuncture needle can be directly inserted into the inside of the plastic tube without being obstructed by the end face of the plastic tube.
[0109] In some embodiments, the first segment 111 and the second segment 112 are coaxially arranged, which is suitable for situations where the first segment 111 and the second segment 112 are respectively adapted to the acupuncture needle and the plastic tube.
[0110] A single positioning slot 11 can simultaneously accommodate acupuncture needles and plastic tubes. In this case, only a single drive structure is needed to drive the positioning slot 11. That is, the acupuncture needles and plastic tubes are transported by the same conveying device, avoiding the need to set up two conveying devices and also avoiding the need to achieve precise synchronous operation of the two conveying devices.
[0111] In some embodiments, the first segment 111 and the second segment 112 in the positioning groove 11 are independent of each other. In this case, the positioning groove 11 can be regarded as being composed of two positioning sub-grooves, that is, two of the above-mentioned conveying devices are used.
[0112] See Figure 7 In this embodiment, the top surface of the positioning plate 14 includes at least one inclined or curved surface for guiding the acupuncture needle and the plastic tube into the positioning groove 11.
[0113] The following explanation uses an inclined plane.
[0114] For ease of understanding and explanation, the positioning plate 14 is provided with only a single positioning groove 11, and the top surface of the positioning plate 14 has two inclined surfaces. The two inclined surfaces are symmetrically arranged on both sides of the opening of the positioning groove 11 to form an inverted V-shape. During operation, taking an acupuncture needle as an example, the acupuncture needle may fall directly into the positioning groove 11, or it may fall into the inclined surface first and then be guided into the positioning groove 11.
[0115] By setting the inclined surface, the probability of the acupuncture needle and the plastic tube entering the positioning groove 11 can be increased, and the requirements for the matching accuracy of each driving structure in this application can be reduced.
[0116] In some embodiments, the top of the positioning plate 14 is provided with one or more interlaced teeth 5. The interlaced teeth 5 may be integrated with the positioning plate 14 or considered as part of the positioning plate 14. The top surface of the interlaced teeth 5 is a sloped or curved surface. The interlaced teeth 5 are provided at the edge of the positioning plate 14, mainly to prevent acupuncture needles from falling between the two positioning plates 14. In some embodiments, the top surface of the interlaced teeth 5 is considered as part of the top surface of the positioning plate 14.
[0117] See Figures 2-5 In this embodiment, the plastic tube alignment assembly 2 includes a drive component 21 and a push plate 22 connected to each other;
[0118] The driving component 21 serves as a component for driving the push plate 22 to move along the length direction of the positioning groove 11;
[0119] Along the length of the positioning groove 11, at least a portion of the projection of the positioning groove 11 coincides with the projection of the push plate 22.
[0120] Through the intermediate structure of push plate 22, drive component 21 drives plastic tubes to move along the length of positioning groove 11 to achieve alignment of each plastic tube, thus avoiding inconsistent assembly effects with acupuncture needles due to different plastic tube positions.
[0121] It should be noted that in some cases, after the acupuncture needles are assembled with the plastic tube, the plastic tube still needs to be assembled with the insert. Before the insert is assembled with the plastic tube, the acupuncture needles are prone to relative movement with the plastic tube. Therefore, some embodiments also include a needle handle alignment component, which is used to align the handles of each acupuncture needle before the insert is assembled with the plastic tube. The specific configuration of the needle handle alignment component can refer to the plastic tube alignment component 2, as long as it meets the above requirements; no specific limitations are made here.
[0122] In some embodiments, the entire projection of the positioning groove 11 coincides with the projection of the push plate 22 along the length direction of the positioning groove 11.
[0123] In some embodiments, the plastic tube needs to be inserted deep into the positioning groove 11. In this case, the surface of the push plate 22 has a protrusion structure that can be inserted deep into the positioning groove 11.
[0124] In some embodiments, in the vertical direction, a portion of the plastic tube protrudes from the positioning groove 11, and in the length direction of the positioning groove 11, the entire projection of the positioning groove 11 is below the projection of the push plate 22. In this case, the push plate 22 directly pushes the protruding portion of the plastic tube, so that even if the plastic tube needs to go deep into the positioning groove 11, it can avoid the need for the push plate 22 to be precisely aligned with the positioning groove 11.
[0125] In some embodiments, the drive element 21 is configured as an existing drive structure such as a drive motor or an electric slide.
[0126] The drive unit 21 is a standard configuration, and its purpose is to drive the push plate 22 to move along a predetermined path, which will not be described in detail here.
[0127] As for the push plate 22, on the one hand, it can realize the alignment of the plastic tube into the predetermined area, so as to avoid the relative position of the acupuncture needle and the plastic tube not being as expected. On the other hand, it can restrict the plastic tube and the acupuncture needle in the length direction of the positioning groove 11, such as restricting the acupuncture needle from completely passing through the plastic tube in case of accident (such as when a large force is applied to the acupuncture needle).
[0128] See Figures 2-5 In this embodiment, the positioning component 3 includes a driver 31 and a positioning element 32 connected to each other;
[0129] The driver 31 serves as a component for vertically driving the positioning member 32 to move;
[0130] The positioning element 32 serves as a component to prevent the acupuncture needle from separating from the positioning groove 11 during the assembly process.
[0131] Without considering the positioning groove 11 driving the acupuncture needle and the plastic tube, during the assembly process, the acupuncture needle moves along the length direction of the positioning groove 11, and needs to be restricted in a direction other than this direction, while the plastic tube needs to remain stationary. Based on this, the positioning component 32 has a completely different effect on the two.
[0132] In some embodiments, the driver 31 is configured as an existing drive structure such as a drive motor or an electric slide.
[0133] In some embodiments, the driver 31 includes two driving structures and the positioning member 32 includes two positioning structures. In this case, the positioning component 3 includes two positioning mechanisms, which respectively position the acupuncture needle and the plastic tube.
[0134] In some embodiments, the positioning component 3 includes a positioning workpiece mounted on the positioning plate 14. The positioning workpiece has a plastic tube groove communicating with the positioning groove 11. It can be understood that the size of the plastic tube is smaller than the positioning groove 11 and is adapted to the plastic tube groove. The opening size of the positioning groove 11 facing upward can be set to be larger than the opening size of the plastic tube groove facing upward. When the plastic tube enters the plastic tube groove under the action of the plastic tube alignment component 2, it cannot move upward.
[0135] Before assembling the acupuncture needle and the plastic tube, the driver 31 drives the positioning member 32 to move downward, so that the positioning member 32 covers at least part of the top opening of the positioning groove 11, thereby simultaneously preventing the acupuncture needle and the plastic tube from separating from the positioning groove 11 during the assembly process, thus facilitating the assembly of the acupuncture needle and the plastic tube.
[0136] It should be noted that, since acupuncture needles are relatively light and small, and since the acupuncture needles move closer to the plastic tube, the positioning element 32 is mainly used to position the acupuncture needles.
[0137] It should also be noted that the specific settings such as the shape of the positioning component 32 can be adjusted according to the positioning groove 11. The positioning component 32 needs to restrict the acupuncture needle from separating from the positioning groove 11 during the assembly process by fitting the top surface of the positioning groove 11, while avoiding affecting the acupuncture needle's approach to the plastic tube. Based on this, the positioning component 32 can be adaptively adjusted through testing.
[0138] See Figure 1 In this embodiment, the blow-needle assembly 4 includes at least one blowpipe 41 for guiding gas to the acupuncture needle.
[0139] It should be noted that the blowpipe 41 only guides gas. The gas (or airflow or compressed gas) is generated by existing devices (such as blowers), which is well known to those skilled in the art and is not specifically limited here.
[0140] See Figure 5In this embodiment, the blowpipe 41 has an air outlet 411 that is inclined toward the transfer assembly 1.
[0141] The tilt angle of the air outlet 411 can be 45 degrees, and no specific limit is imposed here.
[0142] With the configuration of this embodiment, even if the air outlet 411 is not deeply inserted into the positioning groove 11, the gas can still be guided to blow the acupuncture needle, avoiding the blowpipe 41 from affecting the movement of the positioning groove 11, and also avoiding the movement of the positioning groove 11 from causing the blow needle assembly 4 to move.
[0143] See Figure 5 In this embodiment, the longitudinal cross-sectional dimension of the air outlet 411 is larger than the longitudinal cross-sectional dimension of the positioning groove 11.
[0144] To make it easier to understand, in the vertical direction, the projected length of the air outlet 411 is greater than the projected length of the positioning groove 11, or in other words, the width of the air outlet 411 is greater than the width of the positioning groove 11.
[0145] This embodiment is illustrated by showing that a single air outlet 411 guides gas to a single positioning groove 11. Even if the air outlet 411 is not aligned with the positioning groove 11, it can prevent the air outlet 411 from failing to guide the gas to the positioning groove 11 or having a poor guiding effect, thus ensuring that the acupuncture needle can be moved to connect with the plastic tube.
[0146] In some embodiments, a single air outlet 411 supplies air to at least two positioning slots 11, with corresponding dimensions adaptively adjusted.

They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
