[0020] Next, the technical solutions in the embodiments of the present application will be clearly described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0021] Embodiment 1: This embodiment provides an acupuncture needle assembly production line, including: A frame 1, on which a conveyor guide rail 10 is installed, and a plurality of needle handle bases 2 are installed on the conveyor guide rail 10; A needle handle feeding mechanism, installed on the frame 1 and including a plurality of feeding devices 3; A needle handle alignment mechanism 4, installed on the frame 1 and used for aligning the needle handle; A needle body feeding mechanism 5, installed on the frame 1 and used for feeding the needle body; A needle body alignment mechanism 6, installed on the frame 1 and used for aligning the needle body; The welding mechanism 7 is installed on the frame 1 and is used for welding between the tail of the needle body and one end of the needle handle; The detection mechanism 8 is installed on the frame 1 and is used for detecting the welding between the needle body and the needle handle; The blanking mechanism 9 is installed on the frame 1 and is used for differentiating and blanking the products; Among them, the conveying guide rail 10, the way and specific structure for driving a plurality of needle handle seats 2 to move along the conveying guide rail 10 are all prior arts and will not be elaborated here.

[0022] It can be seen from this embodiment that by adopting laser welding between the needle body and the needle handle, the connection strength and stability between the needle body and the needle handle are effectively improved, the service life is effectively extended, and it is not necessary to bend the needle body. At the same time, the production and assembly are in a pipeline manner, effectively improving the production efficiency of the acupuncture needle.

[0023] Embodiment 2: This embodiment provides an acupuncture needle assembly production line. In addition to including the technical solutions of the above embodiment, it also has the following technical features. The needle handle seat 2 includes: A base 20, which is slidably connected to the conveying guide rail 10 and is provided with a first driving member 11 to drive it to move along the conveying guide rail 10; A support seat 21, which is installed on the base 20, and a first groove 22 adapted to the needle handle is equally spacedly opened at the top; A baffle 23, which is installed on the side of the support seat 21 away from each mechanism, and a needle hole 24 adapted to the needle body and coaxial with the needle handle is opened; Among them, the first driving member 11 can be connected to the base 20 by a belt, and the base 20 is provided with guide wheels to cooperate with the conveying guide rail 10, and is driven by a motor and a pulley to drive the belt transmission, which is a conventional setting and will not be elaborated here.

[0024] It can be seen from this embodiment that by arranging the baffle 23 on the support seat 21 and opening the needle hole 24 adapted to the needle body on the baffle 23, it is convenient to limit one end of the needle handle, so as to use the limited end of the needle handle as a reference point to correct and detect the needle handle and the needle body, effectively ensuring the accuracy of acupuncture needle production and the product quality; And by arranging the needle hole 24 on the baffle 23, the stability after the needle body is loaded can be improved, and the risk of the needle body and the needle handle falling off the support seat 21 due to the overlong and overweight needle body of the processed acupuncture needle or moving factors can be avoided.

[0025] Embodiment 3: This embodiment provides an acupuncture needle assembly production line. In addition to including the technical solutions of the above embodiment, it also has the following technical features. The feeding device 3 includes: The storage bin 30 is installed on the frame 1, and its outer side is a transparent panel; The top pusher plates 31 are vertically arranged in the storage bin 30, with a second groove 32 adapted to the needle handle opened at the top, and a second driving member 33 is provided to drive the lifting; The adsorption block 34 is provided with a plurality of adsorption protrusions 35 corresponding to the plurality of top pusher plates 31 on the bottom surface, and a third groove 36 adapted to the needle handle is opened on the adsorption protrusion 35, and a third driving member 37 is provided to drive the translation and lifting; Among them, a first chamber 38 connected to the air extraction device is opened in the adsorption block 34, and a first communication hole 39 communicating with the third groove 36 is opened on the inner wall of the first chamber 38; At the same time, the side of the storage bin 30 closest to the outer side is a transparent panel, and acrylic or glass materials can be used. The specific structure of the air extraction device, the connection and conduction between the air extraction device and the first chamber 38, and the start-stop control of the air extraction device are all prior arts and will not be elaborated here; Moreover, the distance between two adjacent top pusher plates 31 should be such that after the top pusher plate 31 is lifted, a needle handle can be clamped between two adjacent top pusher plates 31. If the distance between two adjacent top pusher plates 31 is too close, multiple needle handles may be clamped between them; The second driving member 33 can adopt a cylinder 41, and the third driving member 37 can adopt a combination of a lead screw transmission assembly and a cylinder 41, which are all conventional settings in the art and will not be elaborated here.

[0026] It can be seen from this embodiment that the top pusher plate 31 with the second groove 32 adapted to the needle handle can ensure that a single top pusher plate 31 only lifts a single needle handle, ensuring the feeding accuracy. And the adsorption block 34 adsorbs the needle handle by the air extraction of the air extraction device, and then moves it to the needle handle seat 2; Moreover, the transparent panel facilitates timely understanding of the stock of needle handles in the storage bin 30 and enables timely replenishment; For the needle handle feeding mechanism, multiple feeding devices 3 are adopted, which can ensure the distance between adjacent top pusher plates 31, prevent the needle handle from being stuck between two top pusher plates 31, and ensure the feeding efficiency. That is, by feeding the single needle handle seat 2 multiple times, it can effectively eliminate the problem of needle handle jamming caused by the too-close distance between two adjacent top pushers under the condition of ensuring the quantity requirement of the single processing amount (such as the needle handle gap on a single needle handle seat 2 is small).

[0027] Embodiment 4: This embodiment provides an acupuncture needle assembly production line. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The needle handle correction mechanism 4 includes: The first bracket 40 is installed on the frame 1 and is equipped with a cylinder 41; The push plate 42 is installed at the output end of the cylinder 41, and under the push of the cylinder 41, one end of the needle handle is abutted against the baffle 23; Among them, the specific structure of the cylinder 41 is the prior art and will not be elaborated here.

[0028] It can be seen from this embodiment that through the cooperation of the push plate 42 and the baffle 23, the two ends of the needle handle can be limited, so as to correct the needle handle, effectively ensuring the processing accuracy, and the structure is simple and the manufacturing cost is low.

[0029] Embodiment 5: This embodiment provides an acupuncture needle assembly production line. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The needle body feeding mechanism 5 includes: The feeding rack 50 is installed with a plurality of wire coils for supplying the needle body; The conveying assembly is installed on the frame 1 and includes a plurality of roller groups 51 for conveying the wire coils; The cutting assembly 52 is installed on the frame 1 and includes a second bracket 520, a guide block 521 and a fourth driving member 522 installed on the second bracket 520, a lower cutting knife 523 installed on the guide block 521, and an upper cutting knife 524 installed on the fourth driving member 522; The pressing assembly 525 is installed on the frame 1 and is used for pressing the needle handle on the support seat 21; Among them, the guide block 521 and the lower cutting knife 523 are both provided with guide holes 526 for the needle body to pass through; At the same time, the wire coil can be made of stainless steel, and the plurality of roller groups 51 and the fourth driving member 522 included in the conveying assembly can adopt the cylinder 41, which are all conventional selections in the prior art. And the plurality of roller groups 51 perform quantitative feeding on the wire, and its specific control is the prior art and will not be elaborated here; And the pressing assembly 525 includes a pressing plate and a cylinder 41 for driving the pressing plate to lift, which is also a conventional selection in the prior art and will not be elaborated here.

[0030] It can be seen from this embodiment that the needle body is fed through the feeding rack 50, and quantitative feeding is performed through the roller groups 51, and then the wire is cut by the cutting assembly 52 to form the needle body, avoiding the separate processing of the needle body and improving the processing efficiency; And the pressing assembly 525 can improve the stability of the needle handle when the needle body penetrates into the needle handle, and the guide block 521 and the provided guide holes 526 facilitate ensuring the stability and accuracy of the needle body feeding.

[0031] Embodiment 6: This embodiment provides an acupuncture needle assembly production line. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The needle body correction mechanism 6 includes: The third bracket 60 is installed on the frame 1; The guiding plates 61, two of which are symmetrically arranged and installed on the third bracket 60, and are provided with a fifth driving member 62 to drive the two guiding plates 61 to translate; The pressing rod 63 is installed on the third bracket 60 and is located above the loading seat, and is used to prevent the needle handle from disengaging from the third groove 36 when the supporting seat 21 moves; Wherein, one end of each of the two guiding plates 61 close to the needle body feeding mechanism 5 is bent away from each other to form a bending portion 64, and the pressing rod 63 extends to the welding mechanism 7; At the same time, the fifth driving member 62 can adopt a cylinder 41, which is a conventional choice in the art and will not be elaborated here.

[0032] It can be seen from this embodiment that through the arrangement of the two guiding plates 61 and in cooperation with the baffle 23, the axial positions of the needle handle and the needle body can be effectively corrected. Specifically, the two ends of the needle handle are limited by one side of the guiding plate 61 and the baffle 23, so as to ensure the position accuracy of the needle handle. And the two guiding plates 61 can limit the two ends of the needle body, so that one end of the needle body can be flush with the needle handle, and the needle body and the two ends of the needle handle on a single needle handle seat 2 are flush, thus effectively ensuring the correction of the needle body, making one end of it flush with one end of the needle handle, so as to ensure the subsequent laser welding between the two and ensure the product quality; And the pressing rod 63 can ensure the position accuracy in the radial direction of the needle body and the needle handle when correcting their axial positions, avoiding deviation and affecting the subsequent laser welding; At the same time, the structure is simple, and the correction of the needle body is completed during the movement of the needle handle seat 2, effectively ensuring the production efficiency and controlling the manufacturing cost.

[0033] Embodiment 7: This embodiment provides an acupuncture needle assembly production line. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The welding mechanism 7 includes: The fourth bracket 70 is installed on the frame 1, and a laser welding machine 71 is installed on the fourth bracket 70; The dust suction assembly 72 is installed on the frame 1, and includes an upper dust suction block 720, a lower dust suction block 721, and a sixth driving member 722 for driving the upper dust suction block 720 and the lower dust suction block 721 to approach or move away from each other; Wherein, one end of the needle handle away from the baffle 23 extends out of the first groove 22, and the upper dust suction block 720 and the lower dust suction block 721 are respectively provided with an upper suction port and a lower suction port 724 on the upper and lower sides of the needle handle extending out of the first groove 22, and a second chamber 725 connected to the air extraction device is opened inside, and second communication holes 726 for communicating the upper suction port and the lower suction port 724 are respectively opened on the inner wall of the second chamber 725; Meanwhile, the specific structure and welding operation principle of the laser welding machine 71 are both existing mature technologies, which can be known by those skilled in the art from the traditional laser welding machine 71, and will not be elaborated here. Moreover, the sixth driving member 722 can adopt the air cylinder 41. The specific structure of the air extraction device, the connection and conduction between the air extraction device and the first chamber 38, and the start-stop control of the air extraction device are all existing conventional selections, and will not be elaborated here.

[0034] As can be seen from this embodiment, through the dust suction assembly 72, it is convenient to suck the smoke and dust generated by laser welding, avoid remaining on the acupuncture needles or affecting the production line environment, ensure green environmental protection during the production process, and by setting the upper suction port and the lower suction port 724, it is ensured that both the floating flue gas and the falling dust can be effectively sucked away, effectively ensuring the treatment effect of the smoke and dust.

[0035] Embodiment 8: This embodiment provides an acupuncture needle assembly production line. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The detection mechanism 8 includes: The fifth support 80 is installed on the frame 1; The first clamping assembly 81 is installed on the fifth support 80, and is slidably connected to one side of the needle handle close to the baffle 23, and includes a first upper clamping plate 810, a first lower clamping plate 811, and a seventh driving member 812 for driving the first upper clamping plate 810 and the first lower clamping plate 811 to approach or separate from each other; The first blanking hopper 82 is installed below the first clamping assembly 81 and is used to collect the needle bodies clamped out by the first clamping assembly 81; Among them, the seventh driving member 812 can adopt the air cylinder 41, which is an existing conventional selection and will not be elaborated here; Meanwhile, in order to ensure that the needle bodies that are not firmly welded between the first upper clamping plate 810 and the first lower clamping plate 811 are pulled out, and to avoid affecting the needle bodies that are firmly welded, the clamping force between the two can be appropriately selected and set to avoid damage to the connection between the firmly welded needle bodies and the needle handle.

[0036] As can be seen from this embodiment, by adopting the method of clamping the needle body to detect whether the connection between the needle body and the needle handle is firm, the structure is simple, the detection effectiveness is high, it is avoided that unqualified products are mixed in, and the processing accuracy and product quality of the products are effectively guaranteed; Meanwhile, the first small hopper can recycle the needle bodies that are not firmly welded, avoid the needle bodies from scattering on the frame 1, and at the same time facilitate the continuous detection of the detection mechanism 8; Moreover, the baffle 23 and the pinholes 24 on the baffle 23 can ensure the limitation of the needle handle, so that the needle bodies that are not firmly welded can be clamped and pulled away by the first clamping assembly 81, while the acupuncture needles that are firmly welded cannot be clamped and pulled away by the first clamping assembly, ensuring that the subsequent blanking mechanism 9 blanks the acupuncture needles that are firmly welded.

The blanking mechanism 9 includes: The sixth bracket 90 is installed on the frame 1; The second clamping assembly 91 is installed on the sixth bracket 90 and is slidably connected to the side of the needle handle away from the baffle 23, and includes a second upper clamping plate 910, a second lower clamping plate 911, and an eighth driving member 912 for driving the second upper clamping plate 910 and the second lower clamping plate 911 to approach or separate from each other; The distinguishing assembly 92 is installed on the bracket and includes two conveyor belts 93 arranged in parallel, and a plurality of convex strips 94 are equidistantly arranged on the conveyor belt 93; The ninth driving member 95 is installed on the frame 1 and is used to drive the conveyor belt 93 to run in a cycle; The second hopper 96 is installed below the second clamping assembly 91 when it is above the distinguishing assembly 92, and is used to collect the needle handles without needle bodies welded; The collection box 97 is installed on one side of the two conveyor belts 93 away from the second hopper 96 and is used to collect the needle handles with needle bodies; Wherein, a fourth groove 98 adapted to the needle handle is formed between multiple adjacent convex strips 94; At the same time, the eighth driving member 912 can adopt a clamping cylinder 41, and the ninth driving member 95 can adopt a combination of a screw drive assembly and a cylinder 41, which are conventional choices in the art and will not be elaborated here; Moreover, one of the two parallel conveyor belts 93 can be slidably connected to the frame 1. Specifically, the two conveyor belts 93 are installed on two mounting brackets. One mounting bracket is fixedly connected to the frame 1, and the other end mounting bracket is connected to the frame 1 through a combination of a slide rail and a slider, and a lead screw drive assembly is provided to drive the mounting bracket to slide on the frame 1. The drive device for driving the two conveyor belts 93 includes a motor and two pulleys installed on the two mounting brackets and used to drive the two conveyor belts 93 to rotate. Non-circular through holes are axially formed in both pulleys, and a bearing bracket is installed on the frame 1, and a linkage shaft adapted to the through holes is provided to connect the two pulleys. The pulley installed on the mounting bracket slidably connected to the frame 1 is axially slidably connected to the linkage shaft. Finally, the motor drives the linkage shaft to rotate to drive the two pulleys to rotate, realizing synchronous conveyance of the two conveyor belts 93, and the two conveyor belts 93 can be adjusted to move closer to and away from each other.

[0038] As can be seen from this embodiment, the acupuncture needles are fed by the two conveyor belts 93. When cooperating with the detection, the needle bodies in the unqualified products are extracted, which causes the lengths of the needle handles with needle bodies and the needle handles without needle bodies to be different in the axial direction, enabling convenient distinction between them, improving the efficiency of differentiated feeding, and having no manual operation, with a simple structure and low manufacturing cost. The multiple convex strips 94 can improve the stability of the movement of the needle handle and ensure perpendicularity to the two conveyor belts 93 in the axial direction, thereby preventing the acupuncture needles with needle bodies from falling between the two conveyor belts 93 and ensuring the differentiation effect.

[0039] Embodiment 10: This embodiment provides a production process for an acupuncture needle assembly production line, including the following steps: S1: The equipment is started, and the conveying guide rail 10 conveys multiple needle handle seats 2. S2: The needle handle is lifted by the ejector plate 31, and the needle handle is adsorbed and placed on the needle handle seat 2 by the adsorption block 34. S3: The push plate 42 pushes the needle handle, and one end of the needle handle abuts against the baffle 23 for calibration and alignment. S4: The pressure component 525 presses the needle handle, and the conveying mechanism conveys the needle body to sequentially pass through the guide hole 526, the needle handle, and the needle hole 24, and the needle body is cut off by the cutting component 52. S5: Through the movement of the needle handle seat 2, the two guide plates 61 calibrate and align the two axial ends of the needle handle and the needle body, and the pressure rod 63 restricts the needle handle and the needle body in the first groove 22. S6: The needle handle and the needle body at one end are welded and connected by the laser welding machine 71, and the dust generated during welding is sucked away by the dust suction component 72. S7: Clamp the welded needle body with the first clamping component 81, and then pull it. The non-welded and fixed needle body is clamped and the clamped-out needle body is collected through the first hopper 82. The welded and fixed needle body is blocked by the baffle 23 due to the needle handle connected thereto and remains on the needle handle seat 2; S8: Clamp the needle handle on the needle handle seat 2 with the second clamping component 91, and place it on two conveyor belts 93. The needle handle without the needle body falls and is collected through the second hopper 96. The needle handle with the needle body is conveyed by the conveyor belt 93 into the collection frame 97; S9: Repeat S2 - S9.

[0040] It can be seen from this embodiment that through the above production process, the automatic assembly of the needle body and the needle handle is carried out in an assembly line manner, with high production efficiency, simple structure, and the detection after welding and the differentiation during blanking are implemented by mechanical structures, resulting in low manufacturing costs.
