Description

Technical Field

[0001] This utility model relates to the field of acupuncture instrument manufacturing, and more specifically to a laser assembly and spot welding device for metal-handled acupuncture needles. Background Technology

[0002] With the continuous development and progress of medical technology, acupuncture is being used more and more in medical treatment and health preservation, and the demand for acupuncture needles is increasing accordingly.

[0003] Currently, there are various methods for connecting the handle and body of metal-handled acupuncture needles on the market. Among them, the traditional laser welding method requires moving the clamp during the spot welding process of acupuncture needles, and there is a servo system positioning time and cooling time, resulting in low welding efficiency.

[0004] For example, Chinese patent CN208214793U discloses an acupuncture needle laser welding machine, which includes a turntable mechanism, a feeding and needle-threading mechanism on the outer periphery of the turntable mechanism, and a laser transfer mechanism on the turntable. The feeding and needle-threading mechanism is used to feed the needle body and thread it into the spring handle. The laser transfer mechanism with a laser welder performs laser welding on the needle body and the spring handle after threading. However, it is difficult to ensure the accurate positioning of the laser welder and the spring handle during the movement of the laser transfer mechanism. Utility Model Content

[0005] 1. Technical problem to be solved by the utility model

[0006] To address the problem of inaccurate laser welding gun positioning during the welding of metal-handled acupuncture needles and needle bodies in existing technologies, this utility model provides a laser assembly and spot welding device for metal-handled acupuncture needles. The device uses a rotating upper needle wheel to sequentially transport the acupuncture needles to the welding station corresponding to the nozzle of the laser welding gun, while simultaneously cooperating with the laser welding gun for precise positioning welding, effectively improving welding efficiency and positioning stability.

[0007] 2. Technical Solution

[0008] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0009] A laser assembly and spot welding device for metal-handled acupuncture needles includes an upper needle wheel, a feeding plate, a laser welding gun, and a receiving bin. The upper needle wheel has parallel needle grooves arranged at equal intervals on its circumference. The lower end of the feeding plate faces the upward-opening needle groove opening. The laser welding gun is mounted on the side of the needle groove, with its nozzle facing a needle groove opening on the upper part of the upper needle wheel. The upper needle wheel and the laser welding gun are located on opposite sides of a mounting plate and are both fixedly connected to the same mounting plate. In practical use, the metal-handled acupuncture needles, already inserted, are fed onto the feeding plate. The grooved design of the upper needle wheel enables automatic feeding, and the rotating upper needle wheel sequentially transports the acupuncture needles to the welding station where the laser welding gun nozzle is located. Simultaneously, the laser welding gun performs precise positioning welding, effectively improving welding efficiency and stability.

[0010] The further spot welding device has a slot at the lower end of the feeding plate, with locking stops on both sides of the needle groove. This prevents the needle from tipping over when the needle body is tilted during feeding. The forward-extending part supports the needle body, preventing the needle from tipping over and falling.

[0011] The further spot welding device has a clamping component above the upper needle wheel to press the acupuncture needle into the needle groove, which facilitates spot welding with the laser welding gun.

[0012] The further spot welding device includes a clamping component comprising a pressure block. The bottom surface of the pressure block is an arc shape with the opening facing downwards, and its curvature is consistent with that of the upper needle wheel, so that the acupuncture needle will not shake in the needle groove, thereby ensuring the stability and precision of the welding process.

[0013] The further spot welding device has a material adjustment plate above the feeding plate near the slot. The bottom of the material adjustment plate and the feeding plate are reserved with a discharge adjustment gap, which can control the discharge amount of acupuncture needles. The larger the gap, the more needles are discharged.

[0014] The further spot welding device has an arc plate on the material dropping surface between the upper needle wheel and the receiving bin. The arc opening faces the material dropping surface, and the arc of the arc plate is consistent with the upper needle wheel, guiding the material to the receiving bin.

[0015] 3. Beneficial effects

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] The laser assembly and spot welding device for metal-handled acupuncture needles of this utility model has a high degree of automation, is easy to operate, and can achieve continuous welding, significantly improving production efficiency. When the upper needle wheel rotates, the movement position is precisely controllable, ensuring that each delivered acupuncture needle can accurately reach the welding position, avoiding offset or misalignment problems. The laser welding forms a hemispherical weld point at the tail end of the needle handle, improving the appearance of the product. Attached Figure Description

Detailed Implementation

[0021] To further understand the contents of this utility model, a detailed description of the utility model is provided in conjunction with the accompanying drawings.

[0022] Example 1

[0023] The laser assembly and spot welding device for the metal-handled acupuncture needles in this embodiment, such as... Figure 1 , 2 As shown, it includes an upper needle wheel 4, a feeding plate 2, a laser welding gun 10, and a receiving bin 3. The upper needle wheel 4 is precision machined, and its circumference surface has parallel needle grooves 41 arranged at equal intervals. The lower end of the feeding plate 2 is directly opposite the opening of the needle groove 41. The laser welding gun 10 is on the side of the needle groove 41, and its nozzle is directly opposite the needle groove 41 opening on the upper part of the upper needle wheel 4. The upper needle wheel 4 and the laser welding gun 10 are arranged on both sides of the mounting plate 1 and are both connected to the same mounting plate 1.

[0024] In this embodiment, the laser assembly and spot welding device for metal-handled acupuncture needles is used to automatically feed metal-handled acupuncture needles that have been inserted but not yet welded. The feeding plate 2 is used to feed the needles, and the slotted needle wheel 4 can automatically feed the needles. The rotating needle wheel 4 then transports the acupuncture needles to the welding station where the laser welding gun 10 is located. At the same time, the laser welding gun 10 is used to perform precise positioning welding, which effectively improves the welding efficiency and stability.

[0025] Example 2

[0026] The laser assembly and spot welding device for metal-handled acupuncture needles in this embodiment has the same basic structure and steps as in Embodiment 1, with the following differences or improvements: Figure 1 , 2 As shown, mounting plate 1 has mounting holes 12, and a fixing plate 11 is detachably connected to the back. A gap is reserved between the fixing plate 11 and the mounting holes 12 for the nozzle of the laser welding gun 10 to pass through. A motor 42 is fixed on the fixing plate 11. The output end of the motor 42 passes through the fixing plate 11 and the mounting plate 1 and is fixedly connected to the upper needle wheel 4 to drive the upper needle wheel 4 to rotate. The rear part of the laser welding gun 10 is detachably connected to the fixing plate 11.

[0027] A slot 21 is provided at the lower end of the feeding plate 2, which engages with the stops on both sides of the needle groove 41. This prevents the needle from tipping over when it is slightly tilted during feeding, and the forward-extending part supports the needle, preventing it from falling. A clamping component 5 is provided above the upper needle wheel 4 to press the acupuncture needle firmly into the needle groove 41, facilitating spot welding by the laser welding gun 10. The clamping component 5 includes a pressure block 51, the bottom surface of which is arc-shaped with the opening facing downwards. Its curvature matches that of the upper needle wheel 4, preventing the acupuncture needle from shaking within the needle groove 41, thus ensuring the stability and accuracy of the welding process. An adjusting plate 6 is provided above the feeding plate 2 near the slot 21. A discharge adjustment gap is reserved between the bottom end of the adjusting plate 6 and the feeding plate 2 to control the discharge amount of the acupuncture needle. The larger the gap, the more needles are discharged. An arc plate 7 is installed on the material dropping surface between the upper needle wheel 4 and the receiving bin 3. The arc opening faces the material dropping surface, and the curvature of the arc plate 7 is consistent with that of the upper needle wheel 4, guiding the material to the receiving bin 3. A sensor 8 for the needle body is installed between the nozzle of the laser welding gun 10 and the slot of the needle groove 41 to detect whether there is a needle in the needle groove 41. If there is no needle, the equipment automatically skips the needle groove 41 without needles to avoid empty welding. The clamping assembly 5 also includes an assembly plate 50, which is convex. Its fixed end is detachably connected to the top surface of the fixed plate 11, and its free end is fixedly connected to the pressure block 51 through a connecting rod. The adjusting plate 6 is fixedly connected to the mounting plate 1 through a clamping block. The arc plate 7 is also fixedly connected to the mounting plate 1.

[0028] The laser assembly and spot welding device for metal-handled acupuncture needles in this embodiment automatically feeds the needles sequentially after they are gathered by the feeding plate 2. The motor 42 drives the upper needle wheel 4 to rotate, and the movement position is precisely controllable. The acupuncture needles are fed sequentially to the welding station where the laser welding gun 10 is located. By simply setting the speed of the motor 42 to match the laser emission frequency of the laser welding gun 10, it can be ensured that each fed acupuncture needle accurately reaches the welding station, avoiding deviation or misalignment. The entire device has a high degree of automation, is easy to operate, and can achieve continuous welding, significantly improving production efficiency. Moreover, the laser welding forms a hemispherical weld point at the tail end of the needle handle, improving the appearance of the finished product.
