Description

Technical Field

[0001] The invention relates to the field of automation, in particular to an acupuncture needle welding device. Background Art

[0002] Acupuncture needles are acupuncture instruments used in traditional Chinese medicine. In recent years, as traditional Chinese medicine treatment methods have gradually spread to the world, the use of acupuncture needles has also increased. Traditional acupuncture needles are made into a curved shape at one end, and then the other end of the needle is inserted into the spring handle and pulled out, leaving the curved end in the spring handle. Although this manufacturing method can fix the needle by forming resistance between the curved part and the spring handle, the contact and fixation of the needle and the spring handle only rely on the friction resistance generated by the two, so there is a risk that the needle and the spring handle will easily separate during use.

[0003] For this reason, a new type of acupuncture needle has emerged. It does not need to be bent, but is directly inserted into the spring handle, and then the end of the needle is welded to the spring handle by laser welding. This type of acupuncture needle effectively solves the problem of the loose connection between the needle and the spring handle of traditional acupuncture needles. However, the manufacturing process of this type of acupuncture needle is complicated, especially the welding step. It is necessary to manually send the acupuncture needles one by one to the bottom of the welding machine for welding one by one, and it is also necessary to manually perform self-inspection and screening. It is not only difficult, but also costly and difficult to mass produce. Summary of the invention

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0025] The present invention provides an acupuncture needle welding device, which realizes automatic welding, detection, kicking and loading and unloading of the needle body and the spring handle. The specific structure is as follows Figures 1 to 6 As shown, it includes a cabinet 1, a back panel 2 vertically installed on the cabinet, a turntable 3 fixed on the back panel for carrying and transporting acupuncture needles, a loading assembly 4 and a unloading assembly 5 fixed on the back panel on one side of the turntable, a kicking assembly 6 located on the other side of the turntable, a blocking assembly 7, a welding assembly 8 and a detection assembly 9 fixed on the back panel above the turntable, wherein the loading assembly is stacked with assembled acupuncture needles, and the blocking assembly is used to deliver the acupuncture needles one by one to the rotating turntable, and the acupuncture needles are rotated by the turntable to the welding assembly for welding, and then the welding quality is detected by the detection assembly, unqualified acupuncture needles are unloaded by the kicking assembly, and qualified acupuncture needles follow the turntable to rotate to the unloading assembly for automatic unloading.

[0026] Specifically, the turntable is fixed on the back plate with a servo motor. The turntable is a nested structure, the middle area is fixed, and the outer ring 31 is controlled to rotate by the servo motor. A plurality of arc grooves 32 for placing acupuncture needles are arranged at intervals on the outer wall of the ring. The arc groove is divided into two sections, front and back. The front section is used to clamp the needle body, and an outer expansion opening 33 is provided at the groove to facilitate the needle body to smoothly enter the outer expansion opening. The rear section of the arc groove is used to load the spring handle, and the welding point is located at the connection between the front and back sections. Since the front and rear positions of the acupuncture needle entering the arc groove are not consistent, there may be front and rear misalignment, and it is difficult to ensure the accuracy of the subsequent laser welding position. For this reason, a guide assembly 10 is arranged on the back plate, which is a guide block fixed on the back plate at the side edge of the turntable. The guide block is a wedge-shaped structure when viewed from above, and the side close to the feeding assembly is narrow, while the side close to the welding assembly is wide. The acupuncture needle entering the arc groove rotates with the turntable, and its tail end moves along the wedge-shaped guide block, thereby ensuring that the welding point position of each acupuncture needle entering the welding assembly is uniform.

[0027] The turntable is fixed on the vertically arranged back plate, that is to say, the turntable is also arranged vertically. Compared with the horizontally arranged turntable, the turntable with this layout does not need to additionally set up a matching fixture for clamping the acupuncture needles. It is only necessary to load the acupuncture needles from one side and rotate them to the highest position for welding. Since the loading and unloading are located on the same side, the welded acupuncture needles need to rotate one circle with the turntable. In order to prevent the acupuncture needles from falling when they rotate to the bottom, a bracket 11 is fixed on the back plate below the turntable. The upper surface of the bracket is a concave semicircular surface, which can wrap the entire lower half of the turntable and effectively prevent the acupuncture needles from falling from the bottom.

[0028] The feeding assembly is arranged on one side of the turntable to realize automatic feeding. Its structure includes a feeding plate 41 arranged obliquely, and a blocking plate 42 located above the feeding plate. The lower end of the feeding plate fits the side wall of the turntable so that the acupuncture needles can roll into the arc groove, and the higher end of the feeding plate is bent inward to form a blocking portion 43 to block the ends of the acupuncture needles piled up inside. The blocking plate is installed obliquely on the back plate in conjunction with a sliding bracket 44. A U-shaped groove for inserting the blocking plate is provided in the sliding bracket, and a plurality of plug holes 45 are provided at intervals on the surface of the blocking plate. The blocking plate is inserted into the U-shaped groove, and a spring latch (not shown) is inserted into different plug holes to limit the upper and lower positions of the blocking plate. When feeding, the blocking plate is lifted so that a gap is formed between its lower edge and the feeding plate to facilitate the passage of the acupuncture needles. When feeding is not required, the blocking plate is lowered so that its lower edge fits the feeding plate, thereby preventing the acupuncture needles from rolling into the turntable.

[0029] To ensure that there is only one acupuncture needle in each arc groove of the turntable, a blocking assembly is provided behind the loading assembly, which includes a blocking block 71 and a mounting frame 72. The lower end face of the blocking block is an arc surface 73 that fits the turntable. At the same time, a triangular bevel surface 74 is provided on the lower end of the side of the blocking block facing the loading assembly. The triangular bevel surface not only prevents multiple acupuncture needles from entering the same arc groove, but also can shovel up the acupuncture needles that are not loaded into place and are stuck at the entrance of the arc groove, thereby ensuring the continuity of the turntable rotation and subsequent welding.

[0030] The welding assembly includes a laser welding head (not shown) and a fixed bracket 81. The laser welding head is fixed to the back plate by the fixed bracket, and the laser welding head is located just above the highest point of the turntable to achieve laser welding of acupuncture needles. The detection assembly is located behind the laser assembly to detect the welding quality. It includes a CCD camera (not shown) and a mounting bracket 91. The CCD camera is used to capture images of welding points to judge the welding quality. If the welding is not in place, the material is removed by kicking out the scrap assembly, and if the welding is qualified, the material is removed by the material removal assembly. The laser welding head and CCD camera are existing equipment, so their structures are not shown in the figure, and only their installation positions are indicated.

[0031] The unloading assembly is located directly below the loading assembly, and its structure includes an unloading plate 51 and a needle shifting rod 52. The unloading plate is horizontally arranged, one end of which extends to the edge of the fixed bracket and fits the side wall of the turntable, and the other end is bent upward to form a blocking structure. The needle shifting rod is L-shaped, one end of which is fixed to the back plate, and the other end extends to the side of the turntable, blocking the acupuncture needle from continuing to rotate upward with the turntable from above, and instead entering the unloading plate along the shifting rod.

[0032] The kick-out assembly is used to remove unqualified acupuncture needles. During the removal process, it is necessary to prevent the acupuncture needles from falling vertically and damaging the needle tips. The structure is as follows Figure 5 As shown, it includes a waste needle blanking plate 61, a needle receiving member 62, a needle blowing tube 63 and a needle feeding roller group 64. The needle receiving member is tilted and fixed on the back plate, located above the waste needle blanking plate, and includes a matching needle receiving upper plate 621 and a needle receiving lower plate 622, and a channel 65 for the acupuncture needles to pass through is formed between the needle receiving upper plate and the needle receiving lower plate. The channel is a sawtooth corrugated structure, and the needle receiving upper plate at the entrance of the channel is an arc structure 651, which is opposite to the turntable. The needle blowing tube is fixed to the middle area of ​​the turntable through a bracket 66, and its end is connected to a compressed air device. The needle blowing tube is used to blow unqualified acupuncture needles into the channel. The arc structure can play a blocking and buffering role when the acupuncture needles are blown in, and then the acupuncture needles fall along the channel of the sawtooth corrugated structure to the waste needle blanking plate below. The design of the arc structure and the sawtooth corrugated structure can make the acupuncture needles always fall in a horizontal state, and there will be no problem of vertical sliding and damaging the needle tip.

[0033] A serrated conveyor belt (sawtooth conveyor belt) is provided on the waste needle blanking plate, and the fallen acupuncture needles are conveyed backwards by means of a conveying servo. The needle feeding roller assembly is provided at the end of the serrated conveyor belt, and includes an upper gear 641 and a lower gear 642 that mesh with each other. The lower gear is fixed on the conveying roller at the end of the serrated conveyor belt, and the upper gear cooperates with the roller shaft 643 to be mounted above the waste needle blanking plate, and the roller surface is in contact with the waste needle blanking plate. The upper and lower gears rotate relative to each other, so that the roller shaft rotates synchronously, and the friction between the roller shaft surface and the surface of the waste needle blanking plate is used to continue to convey the acupuncture needles at the end of the serrated conveyor belt backwards.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
