[0002] In the production process of acupuncture needles, the precision, quality, and consistency of the needle tip are important factors in ensuring their therapeutic effect. The spring-wound core wire of the acupuncture needle is a key part of the acupuncture needle structure. It is responsible for providing the necessary tension and elasticity to ensure that the acupuncture needle can stably and accurately transmit the therapeutic effect during treatment.

[0003] Dynamic balancing tests are used to check the balance of a spring in motion. Since the springs of acupuncture needles need to withstand a certain amount of tension and vibration, dynamic balancing tests are particularly important to ensure that the springs will not cause abnormal behavior due to imbalance during actual use. However, existing acupuncture needle spring testing devices are difficult to use core wires to tension the springs and cannot monitor the tension and strain of the springs in real time during the tensioning process, which needs further improvement.

[0004] Therefore, an acupuncture needle spring winding core wire linkage tensioning and stretching detection device is proposed, which can use the core wire tensioning spring to monitor the spring tension and tension in real time during the tensioning and stretching process. Utility Model Content

[0034] In use, the acupuncture needle body 10 is attached to the detection mechanism 9.

The rope 13 is tied to the through hole 507. The pull-down mechanism 3 is activated to pull down the first steel wire rope 303, and the pull-up mechanism 4 is activated to pull up the second steel wire rope 406. Then, the motor 501 is activated so that the lead screw body 502 rotates in both directions, which can drive the acupuncture needle body 10 to rotate in both directions. So that while the acupuncture needle body 10 is rotating, the gaps of the acupuncture needle spring 11 are pulled down and up by the pull-down mechanism 3 and the pull-up mechanism 4, respectively.

[0035] Please see Figure 1 and Figure 2 In this embodiment, support legs 101 are fixedly connected to the four corner edges of the lower end of the support plate 1, and the lower ends of the four support legs 101 are fixedly connected to the base plate 102, which facilitates the stable placement of the support plate 1.

[0036] Please see Figure 1 and Figure 6 In this embodiment, the limiting mechanism 8 includes a fourth electric cylinder 801, a pressure block 802, an outer ring 803, and an inner ring 804. The outer ring 803 and the inner ring 804 are placed on the upper end of the support plate 1. The outer ring 803 is located outside the inner ring 804. Two opposing fourth electric cylinders 801 are fixedly connected to the upper end of the support plate 1. A pressure block 802 is fixedly connected to the output shaft of the fourth electric cylinder 801. The ends of the two pressure blocks 802 that are close to each other are in contact with the side wall of the outer ring 803. Opening the two opposing fourth electric cylinders 801 makes the two pressure blocks 802 close to each other, which can squeeze and limit the outer ring 803.

[0037] Please see Figure 1 and Figure 6 In this embodiment, the inner diameter of the outer ring 803 is larger than the outer diameter of the inner ring 804, and the gap between the outer ring 803 and the inner ring 804 facilitates the limiting of the detection mechanism 9.

[0038] Please see Figure 1 and Figure 7In this embodiment, the detection mechanism 9 includes a fixed cylinder 901, a groove 902, a movable arm 903, a limiting post 904, an acceleration sensor 905, and a vibration sensor 906. The fixed cylinder 901 is positioned above the support plate 1. A groove 902 is formed at the upper end of the fixed cylinder 901. Two movable arms 903 are fixedly connected to the side wall of the fixed cylinder 901. A limiting post 904 is fixedly connected to the lower end of each movable arm 903. An acceleration sensor 905 is fixedly connected to one side of each movable arm 903, and a vibration sensor 906 is fixedly connected to the other side. The side wall of the limiting post 904 is located between the outer ring 803 and the inner ring 804. The lower end of arm 903 is attached to the upper end of outer ring 803 and inner ring 804 respectively. The side wall of acupuncture needle body 10 is attached to the inner wall of fixing cylinder 901. Acupuncture needle body 10 is placed on the inner wall of fixing cylinder 901. Strong adhesive is applied to the inner wall of groove 902 to bond acupuncture needle body 10 and fixing cylinder 901 together. Limiting post 904 can move stably along the inner wall of outer ring 803 and the outer wall of inner ring 804. When acupuncture needle body 10 rotates, the acceleration of moving arm 903 can be measured by acceleration sensor 905. When vibration sensor 906 is turned on, the vibration of acceleration sensor 905 can be measured.

[0039] Please see Figure 1 , Figure 6 and Figure 9 In this embodiment, the camera mechanism includes a display screen 601 and a camera 602; the camera 602 is fixedly connected to one end of the upright plate 6 near the connecting block 5, and the display screen 601 is fixedly connected to the other end of the upright plate 6 away from the connecting block 5. When the camera 602 is turned on, it can record the state of the acupuncture needle body 10 when it rotates.

[0040] Please see Figure 1 and Figure 9 In this embodiment, the extrusion mechanism 7 includes a third electric cylinder 701 and a second U-shaped block 702. The third electric cylinder 701 is fixedly connected to one end of the upright plate 6 near the connecting block 5. The second U-shaped block 702 is fixedly connected to the output shaft of the third electric cylinder 701. The inner wall of the second U-shaped block 702 is in contact with the side wall of the acupuncture needle body 10. Activating the third electric cylinder 701 causes the second U-shaped block 702 to move to the side wall of the acupuncture needle body 10, which can stably limit the position of the acupuncture needle body 10.

[0041] Example 2: Please refer to Figure 4 Based on Embodiment 1, this application provides a technical solution: the inner walls of both sides of the fixed wheel 506 are flush with the inner walls of both sides of the U-shaped seat 404.

[0042] One end of the second steel wire rope 406 is passed through one of the guide wheels 405 and fixed to the side wall of the fixed wheel 506. Since the first U-shaped block 505 will move in the vertical direction, when the first U-shaped block 505 moves upward, it can pull the second steel wire rope 406, thereby pulling the gap of the acupuncture needle spring 11 at an inclined angle, and the acceleration and vibration value of the detection mechanism 9 can be detected at this time.

[0043] Working principle: First, the acupuncture needle body 10 is placed on the inner wall of the fixed cylinder 901. Strong adhesive is applied to the inner wall of the groove 902 to bond the acupuncture needle body 10 and the fixed cylinder 901 together. The limiting post 904 can move stably along the inner wall of the outer ring 803 and the outer wall of the inner ring 804. When the acupuncture needle body 10 rotates, the acceleration of the movable arm 903 can be measured by the acceleration sensor 905. The vibration sensor 906 can be turned on to measure the vibration of the acceleration sensor 905.

[0044] Then, the two opposing fourth electric cylinders 801 are activated so that the two pressure blocks 802 are brought closer to each other, which can squeeze and limit the outer ring 803. The gap between the outer ring 803 and the inner ring 804 facilitates the limiting of the detection mechanism 9.

[0045] The opening limit mechanism 8 moves the outer ring 803, so that two of the gaps of the acupuncture needle spring 11 on the acupuncture needle body 10 are located on the side walls of the first steel wire rope 303 and the second steel wire rope 406, respectively.

[0046] Then, the cord 13 is tied to the through hole 507, the pull-down mechanism 3 is turned on to pull down the first wire rope 303, and the pull-up mechanism 4 is turned on to pull up the second wire rope 406. At the same time, the motor 501 is turned on to make the screw body 502 rotate forward and backward, which can drive the acupuncture needle body 10 to rotate forward and backward. This allows the acupuncture needle body 10 to rotate while the acupuncture needle spring 11 is being pulled down and up by the pull-down mechanism 3 and the pull-up mechanism 4, respectively.

[0047] By testing the acceleration and vibration state of the testing mechanism 9 at this time, the tension and strain of the acupuncture needle spring 11 can be monitored in real time.

[0048] Alternatively, one end of the second steel wire rope 406 can be passed through one of the guide wheels 405 and fixed to the side wall of the fixed wheel 506. Since the first U-shaped block 505 will move in the vertical direction, when the first U-shaped block 505 moves upward, the second steel wire rope 406 can be pulled, thereby pulling the gap of the acupuncture needle spring 11 at an inclined angle, and the acceleration and vibration value of the detection mechanism 9 can be detected at this time.

[0049] During the testing process, turning on the camera 602 can record the state of the acupuncture needle body 10 as it rotates, and turning on the third electric cylinder 701 can move the second U-shaped block 702 to the side wall of the acupuncture needle body 10, which can stably limit the position of the acupuncture needle body 10.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
