Abstract
Description
Technical Field
[0001] This utility model relates to the field of acupuncture needle processing technology, specifically to an automatic material feeding and threading mechanism for cutting wires. Background Technology
[0002] The specific composition and production methods of acupuncture needles vary. In one production method, the ends of rolled filaments are sequentially passed through multiple guide tubes (used to plan the movement path of the filaments), and a traction device pulls the ends of the filaments to move. Subsequently, the ends of the filaments need to be inserted into the tube structure (filament threading process) to form an acupuncture needle. Afterward, the filaments need to be cut to form new ends. This method has the following problems:
[0003] 1. The quality of the filament is unstable and it is easy to bend, which may increase the frequency of failures in the filament threading process and affect production capacity.
[0004] 2. The winding and coiling of the yarn makes it easy for the yarn to become tangled, further increasing the probability of malfunctions during the yarn threading process.
[0005] 3. Switching to coiled yarn takes longer and is less efficient, further impacting production capacity.
[0006] Therefore, how to solve the problem of increased frequency of failures in the threading process and insufficient production capacity in the existing technology has become the research topic to be solved by this utility model. Utility Model Content
[0007] The purpose of this invention is to provide an automatic wire cutting, feeding, and threading mechanism.
[0008] To achieve the above objectives, the technical solution adopted by this utility model is as follows:
[0009] The automatic wire cutting, feeding, and threading mechanism includes:
[0010] Processing table;
[0011] A feeding hopper, installed on the processing table, is used to store cut wires;
[0012] The material distribution assembly is installed on the processing table and has multiple material distribution slots with upward openings for accommodating cut wires. Each of the material distribution slots is spaced apart along a first direction and can move vertically relative to the processing table.
[0013] A fixing component, installed on the processing table, is used to fix the sleeve structure of the corresponding cutting wire;
[0014] A pushing component, installed on the processing table, is used to push a portion of the cut wire into the separation area into the sleeve structure along a second direction, wherein the second direction, the first direction, and the vertical direction are orthogonal to each other.
[0015] In the above-mentioned solution, the acupuncture needle of this utility model is composed of a cutting wire and a sleeve structure. The cutting wire serves as the needle body and its head can be processed to form a needle tip. The sleeve structure serves as the needle handle and is generally in the shape of a round tube.
[0016] The filaments are pre-cut and straightened to form cut filaments. The processing method is not limited here. The cut filaments are fed into the feeding hopper for storage. Then, the cut filaments in the feeding hopper are manually arranged onto the material distribution component. Some of the cut filaments fall into the material distribution trough. Then, the material distribution trough rises, causing the cut filaments in the material distribution trough to separate from other cut filaments. This completes the material distribution process. Next, the pushing component pushes the cut filaments in the material distribution trough so that some of them are inserted into the sleeve structure. The sleeve structure is then fixed by the fixing component. This completes the threading process.
[0017] The cut wire has been pre-cut and straightened, eliminating the problems of bending and tangled wires, thus reducing the probability of failure during the wire threading process. In addition, during the material change process, since there is no need to replace the entire spool of wire or perform operations such as pulling the ends of the spool, the material change speed is fast, the processing efficiency is high, and the production capacity is guaranteed.
[0018] In a further technical solution, the material distribution component includes a support base, a movable base, and a drive unit. The drive unit and the support base are both mounted on the processing table. The movable base is engaged with the support base. The material distribution groove is disposed on the movable base. The drive unit can drive the movable base to move vertically.
[0019] After the cutting wires in the feeding hopper are manually arranged onto the distribution assembly, several cutting wires are arranged on the top of the support base and the moving base. The top surfaces of the support base and the moving base are on the same plane. The distribution slots are set corresponding to the cutting wires, and each distribution slot can only hold one cutting wire. After the cutting wire enters the distribution slot, both ends of the cutting wire are outside the distribution slot. The drive unit can be set as an existing device such as a cylinder. The drive unit drives the moving base to rise, thereby separating the cutting wires in the distribution slot from other cutting wires.
[0020] A further technical solution includes a rejection component, disposed on one side of the material distribution component, used to reject cut wires that are close to and outside the material distribution trough after the material distribution trough enters the separation area. Generally, one material distribution trough can only accommodate one cut wire, but considering factors such as possible adhesion between cut wires, a rejection component is needed for processing.
[0021] A further technical solution includes a rejection assembly comprising a driving component and a rejection component connected together. The driving component can drive the rejection component to move along a first direction. The rejection component is used to reject cut wires that are close to and outside the material distribution trough after the material distribution trough enters the separation area. The portion of the rejection component that contacts the cut wire is flexible. The rejection component is an actual rejection structure, and the flexible portion of the rejection component that contacts the cut wire avoids damage to the cut wire and allows for sufficient contact with the cut wire.
[0022] A further technical solution also includes a limiting part disposed above the material distribution assembly to prevent the cut wire in the separation area from being tilted within the material distribution trough.
[0023] A further technical solution includes a fixing component comprising a mounting base, a pressing component, and an output component. The mounting base is mounted on the processing table, and the output component is connected to the pressing component and can vertically drive the pressing component to press the sleeve structure placed on top of the mounting base. The mounting base is placed on top of the processing table, and it cooperates with the pressing component to fix the sleeve structure; the two can be regarded as a lower mold and an upper mold.
[0024] A further technical solution involves providing multiple fixing grooves spaced apart along a first direction at the top of the mounting base, and / or providing multiple fixing grooves spaced apart along a first direction at the bottom of the pressing member. When the fixing grooves are located at the top of the mounting base, the sleeve structure can be pre-fixed before the pressing member presses it down, preventing the sleeve structure from leaving its predetermined position. The fixing grooves also indicate to the operator the correct placement of the sleeve structure. When the fixing grooves are located at the bottom of the pressing member, the pressing member can be lowered first, and then the end of the sleeve structure can be inserted into the fixing groove. The fixing grooves can also guide the cutting wire.
[0025] A further technical solution includes a pushing assembly comprising a traction mechanism and a threading mechanism connected together. The traction mechanism is mounted on the processing table and drives the threading mechanism to move along a second direction. The threading mechanism is slidably mounted on the processing table and pushes a portion of the cut wire into the sleeve structure along the second direction. The traction mechanism drives the threading mechanism to move along the second direction, and the threading mechanism gradually approaches each cut wire in the separation area. Then, the threading mechanism pushes these cut wires to partially insert them into the sleeve structure, thus realizing the threading process.
[0026] A further technical solution includes a wire threading mechanism comprising a sliding seat, an output section, and a clamping section connected in sequence. The sliding seat is slidably mounted on the processing table and connected to the traction mechanism. The clamping section has a first clamping end and a second clamping end. The output section can drive the first clamping end and the second clamping end to clamp the cut wire. After the output section drives the first clamping end and the second clamping end to clamp the cut wire, the material distribution groove is reset, and the support structure for the cut wire is replaced by the first clamping end and the second clamping end. This clamping method ensures the stability of the cut wire during subsequent movement, thereby ensuring the alignment of the cut wire with the sleeve structure.
[0027] In a further technical solution, the first clamping end is located below the second clamping end, and the end of the first clamping end near the fixing component is provided with an alignment groove. The sidewall of the alignment groove can push each cutting wire in the separation area to move so that its ends are aligned.
[0028] The second clamping end has a pressing protrusion corresponding to the alignment groove at its bottom end near the fixing component. In the first clamping end, the parts that actually contact the cutting wires are the sidewall and bottom wall of the alignment groove. The sidewall of the alignment groove contacts each cutting wire in the separation area at different time periods, ultimately achieving that each cutting wire in the separation area is aligned and set in the alignment groove, avoiding the distance of these cutting wires being inserted into the sleeve structure later from being inconsistent with the predetermined distance.

[0032] Unless otherwise specified, the terms used herein generally have their ordinary meaning in the context of the art, the subject matter, and the specific context. Certain terms used to describe this case will be discussed below or elsewhere in this specification to provide additional guidance to those skilled in the art in describing the case.

In this case, they are only used to describe the positional relationship between the structures and are not intended to limit the specific direction of the protection scheme or its actual implementation.
[0034] The working principle and advantages of this utility model are as follows: The filament is pre-cut and straightened to form cut filaments. The cut filaments are fed into the feeding hopper for storage, and then arranged on the material distribution assembly. Some of the cut filaments fall into the material distribution trough. Subsequently, the material distribution trough rises, separating the cut filaments in the trough from other cut filaments, thus completing the material distribution process. Next, the pushing assembly pushes the cut filaments in the material distribution trough to insert them partially into the sleeve structure, which is then fixed by the fixing assembly, thus completing the threading process. The pre-cut and straightened filaments eliminate the problems of bending and tangled wires, thereby reducing the probability of failure during the threading process. In addition, during the material change process, since it is not necessary to replace the entire spool of filament or perform operations such as pulling the ends of the filament, the material change speed is fast, the processing efficiency is high, and the production capacity is guaranteed.

[0045] The present invention will be further described below with reference to the accompanying drawings and embodiments:
[0046] 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.
[0047] 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.
[0048] See Figures 1-9 The automatic wire cutting, feeding, and threading mechanism includes:
[0049] Processing table 1;
[0050] The feeding bin 2 is installed on the processing table 1 and is used to store the cut wires 9;
[0051] The material distribution assembly 3 is installed on the processing table 1 and has a plurality of material distribution grooves 34 for accommodating the cut wires 9 with the openings facing upwards. Each of the material distribution grooves 34 is arranged at intervals along a first direction and can move vertically relative to the processing table 1.
[0052] Fixing component 4 is installed on the processing table 1 and is used to fix the sleeve structure 8 corresponding to the cutting wire 9;
[0053] The pushing component 5 is installed on the processing table 1 and is used to push a portion of the cutting wire 9 into the separation area into the sleeve structure 8 along the second direction. The second direction, the first direction, and the vertical direction are orthogonal to each other.
[0054] The first direction is parallel to Figure 1 In the X direction, the second direction is parallel to Figure 1 Center Y direction.
[0055] The processing table 1 is a standard setting and is not specifically limited here. The purpose of the processing table 1 is to support, fix and raise some structures in this application, and it is sufficient to achieve these effects.
[0056] The feeding bin 2 is used to store the cut wires 9. The storage operation is a conventional setting. Therefore, the feeding bin 2 is not specifically limited here and can be set as a conventional box-type structure.
[0057] The filaments are pre-cut and straightened to form cut filaments 9. The processing method is not limited here. The cut filaments 9 are fed into the feeding bin 2 for storage. Then, the cut filaments 9 in the feeding bin 2 can be manually arranged onto the material distribution component 3. Some of the cut filaments 9 fall into the material distribution groove 34. Then, the material distribution groove 34 rises to separate the cut filaments 9 in the material distribution groove 34 from other cut filaments 9, thus completing the material distribution process. Next, the pushing component 5 pushes the cut filaments 9 in the material distribution groove 34 so that some of them are inserted into the sleeve structure 8. The sleeve structure 8 is fixed by the fixing component 4, thus completing the wire threading process.
[0058] The cut wire 9 has been pre-cut and straightened, so there are no problems with bending or tangled wires, which reduces the probability of failure during the wire threading process. In addition, during the material change process, since there is no need to replace the whole spool of wire or perform operations such as pulling the ends of the spool, the material change speed is fast, the processing efficiency is high, and the production capacity is guaranteed.
[0059] Part of the cut wire 9 is inserted into the sleeve structure 8, and at this point, the acupuncture needle is formed. The cut wire 9 is the needle wire, and the sleeve structure 8 serves as the needle handle and is generally in the shape of a round tube.
[0060] See Figure 2 , Figure 4 , Figure 8 In this embodiment, the material distribution component 3 includes a support base 31, a movable base 32, and a drive unit 33. The drive unit 33 and the support base 31 are both installed on the processing table 1. The movable base 32 is engaged with the support base 31. The material distribution groove 34 is disposed on the movable base 32. The drive unit 33 can drive the movable base 32 to move vertically.
[0061] After the cutting wires 9 in the feeding bin 2 are manually arranged onto the material distribution assembly 3, several cutting wires 9 are arranged on the top of the support base 31 and the moving base 32. The top surfaces of the support base 31 and the moving base 32 are on the same plane. The material distribution groove 34 is set corresponding to the cutting wires 9. One material distribution groove 34 can only accommodate one cutting wire 9, and after the cutting wire 9 enters the material distribution groove 34, both ends of it are outside the material distribution groove 34.
[0062] The drive unit 33 can be configured as an existing device such as a cylinder. The drive unit 33 drives the movable seat 32 to rise, thereby separating the cutting wire 9 in the material distribution groove 34 from other cutting wires 9. The movable seat 32 is initially supported by the support seat 31, and in the above process, it is supported by the drive unit 33. The drive unit 33 does not need to be connected to the movable seat 32. In order to facilitate the drive unit 33 to drive the movable seat 32, the support seat 31 is generally provided with a through hole, and the movable seat 32 has a protruding structure. This protruding structure passes through the through hole on the support seat 31 and is used to contact the drive unit 33.
[0063] The movable seat 32 and the support seat 31 are engaged. For example, the support seat 31 has multiple grooves, and the movable seat 32 includes multiple plate-like structures. Each plate-like structure is initially inserted into its respective groove. A material distribution groove 34 is disposed at the top of each plate-like structure, and each plate-like structure is connected to the aforementioned protruding structure via a connecting structure. It should be emphasized that the support seat 31 is mainly used to support the movable seat 32, and its specific shape and other configurations can be chosen in several ways. The key structure of the movable seat 32 is the material distribution groove 34. The movable seat 32 needs to contact the support seat 31 or the drive unit 33 at different stages, and the specific structure can also be chosen in several ways; neither needs to be specifically limited.
[0064] See Figure 1 In this embodiment, a rejection component 6 is also included, which is disposed on one side of the material distribution component 3, and is used to reject the cut wires 9 that are close to the material distribution 34 and located outside the material distribution 34 after the material distribution trough 34 enters the separation area.
[0065] It should be noted that although it is mentioned above that a material distribution trough 34 can only accommodate one cutting wire 9, considering factors such as possible adhesion between cutting wires 9, a rejection component 6 needs to be set up for processing. Taking a single material distribution trough 34 as an example, when this material distribution trough 34 enters the separation area, there will be a cutting wire 9 inside. If there is a second cutting wire 9 at its opening, it will be rejected by the rejection component 6.
[0066] See Figure 2 In this embodiment, the rejection component 6 includes a drive member 61 and a rejection member 62 connected to each other. The drive member 61 can drive the rejection member 62 to move along a first direction. The rejection member 62 is used to reject the cut wire 9 that is close to the material distribution trough 34 and located outside the material distribution trough 34 after the material distribution trough 34 enters the separation area. The part of the rejection member 62 that is used to contact the cut wire 9 is flexible.
[0067] Optionally, the drive unit 61 can be set as an existing device such as an electric slide table. Here, the support problem is also explained using the drive unit 61 as an example. The support of the structure is a conventional setting. Therefore, even if it is not clear how the drive unit 61 is supported, it should not be denied that the drive unit 61 cannot operate stably. It is also mentioned here that the drive unit 61 can be connected to the processing table 1, or a support frame can be set to support it. Both are conventional settings and will not be described in detail. The connection method is also a conventional setting and will not be described in detail.
[0068] The rejecting component 62 is the actual rejecting structure, which can be set as a brush or a combination of a brush and a support rod. The part of the rejecting component 62 that is used to contact the cutting wire 9 is flexible, so the bristles of the brush are also flexible, avoiding damage to the cutting wire 9 and allowing full contact with the cutting wire 9.
[0069] See Figure 1 , Figure 3 In this embodiment, a limiting part 7 is also included, which is disposed above the material distribution component 3 to prevent the cut wire 9 in the separation area from being tilted in the material distribution groove 34.
[0070] Optionally, the limiting part 7 includes a limiting plate and may also include a structure supporting the limiting plate. The purpose of the limiting part 7 is to prevent the cut wire 9 in the separation area from being tilted in the material distribution groove 34. This structure may be omitted depending on actual needs.
[0071] See Figure 2 , Figure 4 , Figure 6 In this embodiment, the fixing component 4 includes a mounting base 41, a pressing component 42, and an output component 43. The mounting base 41 is mounted on the processing table 1, and the output component 43 is connected to the pressing component 42 and can drive the pressing component 42 vertically to press the sleeve structure 8 placed on top of the mounting base 41.
[0072] Mounting base 41 is placed on top of processing table 1, and it is fitted with pressing component 42 to fix structure 8. The two can be regarded as lower mold and upper mold. Output component 43 can be set as existing device such as cylinder. Mounting base 41 is a fixed structure, while pressing component 42 can move vertically driven by output component 43.
[0073] See Figure 6 In this embodiment, the top end of the mounting base 41 is provided with a plurality of fixing grooves 44 spaced apart along the first direction, and / or the bottom end of the pressing member 42 is provided with a plurality of fixing grooves 44 spaced apart along the first direction.
[0074] The loading and unloading of the sleeve structure 8 can be done manually. The sleeve structure 8 needs to be placed in a predetermined position to align with the cutting wire 9. When the fixing groove 44 is set at the top of the mounting base 41, the sleeve structure 8 is placed in the fixing groove 44. The size of the fixing groove 44 is set according to the size of the sleeve structure 8. This allows the sleeve structure 8 to be pre-fixed before the pressing part 42 presses it down, preventing the sleeve structure 8 from leaving the predetermined position before the pressing part 42 presses it down. The setting of the fixing groove 44 also reminds the operator of the required placement position of the sleeve structure 8. The number and size of the fixing groove 44 are set as standard and will not be elaborated here. When the fixing groove 44 is set at the bottom of the pressing part 42, the pressing part 42 can be lowered first and then the end of the sleeve structure 8 can be inserted into the fixing groove 44. The fixing groove 44 can also guide the cutting wire 9. The fixing groove 44 can be set at both the bottom of the pressing part 42 and the top of the mounting base 41.
[0075] See Figure 1 In this embodiment, the pushing component 5 includes a traction mechanism 51 and a threading mechanism 52 connected to each other. The traction mechanism 51 is installed on the processing table 1 and is used to drive the threading mechanism 52 to move in the second direction. The threading mechanism 52 is slidably installed on the processing table 1 and is used to push a portion of the cut wire 9 into the sleeve structure 8 in the second direction.
[0076] Optionally, the traction mechanism 51 can be configured with an existing servo drive device, such as a linear motor-driven conveyor belt system or a servo traction device (refer to a fully automatic roll wrapping machine). The purpose of the traction mechanism 51 is to drive the threading mechanism 52 to move in the second direction; therefore, linear drive devices such as electric slides or conveyors can also be used.
[0077] The traction mechanism 51 drives the threading mechanism 52 to move along the second direction. The threading mechanism 52 gradually approaches each cut wire 9 in the separation area. Then, the threading mechanism 52 pushes these cut wires 9 so that they are partially inserted into the sleeve structure 8 to realize the threading process.
[0078] See Figure 1 , Figure 4 , Figure 5 In this embodiment, the threading mechanism 52 includes a sliding seat 521, an output part 522, and a clamping part 523 connected in sequence. The sliding seat 521 is slidably mounted on the processing table 1 and connected to the traction mechanism 51. The clamping part 523 has a first clamping end 5231 and a second clamping end 5232. The output part 522 can drive the first clamping end 5231 and the second clamping end 5232 to clamp the cut wire 9.
[0079] The traction mechanism 51 drives the sliding seat 521 to move along the second direction. The sliding seat 521 then drives the output part 522 and the clamping part 523 to move along the second direction. The output part 522 can also drive the clamping part 523 to move relative to the sliding seat 521.
[0080] The output unit 522 can drive the first clamping end 5231 and the second clamping end 5232 to clamp the cutting wire 9. After that, the material distribution groove 34 is reset, and the support structure of the cutting wire 9 is replaced by the first clamping end 5231 and the second clamping end 5232. This clamping method can ensure the stability of the cutting wire 9 in the subsequent movement process, thereby ensuring that the cutting wire 9 is aligned with the sleeve structure 8.
[0081] Alternatively, the output unit 522 may be configured as a cylinder or a similar existing device.
[0082] Alternatively, the clamping part 523 may be configured as an electric clamp or a similar existing device.
[0083] Optionally, the processing table 1 is provided with a slide rail, and the sliding seat 521 is slidably connected to the processing table 1 through the slide rail.
[0084] See Figure 5 In this embodiment, the first clamping end 5231 is located below the second clamping end 5232. The end of the first clamping end 5231 near the fixed component 4 is provided with an alignment groove 5233. The sidewall of the alignment groove 5233 can push each cutting wire 9 in the separation area to move so that its ends are aligned.
[0085] The second clamping end 5232 has a pressing protrusion 5234 at the bottom of the end near the fixing component 4, corresponding to the alignment groove 5233.
[0086] It should be noted that the cutting wires 9 in the material distribution groove 34 are prone to being misaligned, which may cause some cutting wires 9 to be inserted into the sleeve structure 8 at a distance that does not match the predetermined distance.
[0087] The structure of the alignment groove 5233 can be referred to in the attached drawing. For ease of understanding, the alignment groove 5233 is also set as an L-shaped groove. In the first clamping end 5231, the parts that actually contact the cutting wire 9 are the side wall and bottom wall of the alignment groove 5233. The side wall of the alignment groove 5233 contacts each cutting wire 9 in the separation area at different time periods, and finally realizes that each cutting wire 9 in the separation area is aligned in the alignment groove 5233, so as to avoid the distance of these cutting wires 9 being inserted into the sleeve structure 8 later from not matching the predetermined distance. This alignment process occurs before the clamping process.
[0088] The shape of the pressing protrusion 5234 is adapted to the shape of the alignment groove 5233. For example, when the alignment groove 5233 is an L-shaped groove, the pressing protrusion 5234 is also L-shaped.
[0089] As mentioned above, the first clamping end 5231 and the second clamping end 5232 clamp the cutting wire 9. Specifically, the cutting wire 9 is clamped on the bottom surface of the pressing protrusion 5234 and the surface of the alignment groove 5233 that is directly opposite to the bottom surface of the pressing protrusion 5234 (i.e., the bottom wall of the alignment groove 5233).
[0090] The clamping part 523 is summarized here. On the one hand, the clamping part 523 aligns the ends of the multiple cutting wires 9; on the other hand, the clamping part 523 clamps and fixes the ends of the cutting wires 9 so that they are aligned with the sleeve structure 8; and on yet another hand, the clamping part 523 drives the cutting wires 9 to move and ensures their stability during the movement.
[0091] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. 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.
