Technical Field

The invention relates to the field of Hunan embroidery robots, in particular to an embroidery needle for Hunan embroidery robots.

Background

Hunan embroidery is one of four famous embroideries in China, has a long history and extremely high cultural and artistic value, and is selected as the first national-grade non-material cultural heritage protection directory in 2006. The non-heritage protection of Hunan embroidery gradually develops from master identification, knowledge arrangement, cultivation of the embroidery woman and industry support to the current artificial intelligence stage, and the artificial intelligence technology is a necessary choice for promoting the non-heritage protection of Hunan embroidery and the industry development. In view of the uniqueness of Hunan embroidery thread, embroidery cloth and stitching, the development of high-quality Hunan embroidery cannot be completed on the existing computerized embroidery machine, various improvement measures cannot meet the requirements of thin Hunan embroidery thread, thin embroidery cloth and flexible stitching, and the finished Hunan embroidery cannot achieve the visual effects of neat, smooth, straight, even, thin, smooth and dense Hunan embroidery.

The embroidery needle of the existing computer embroidery machine is designed aiming at the traditional machine embroidery, has the advantages of simple structure and high efficiency, but the pulling force to the embroidery thread in the embroidery process is large, only single-side embroidery can be carried out, and the embroidery is thick and lack of luster, so the embroidery needle is not suitable for Hunan embroidery robots. In addition, the traditional machine embroidery has fixed embroidery needles, is difficult to realize the Hunan embroidery process and Hunan embroidery stitch method, and further cannot meet the requirement of Hunan embroidery robots on accurate detection of the positions of the embroidery needles and reduce the tension of the embroidery needles on embroidery threads.

Disclosure of Invention

In order to solve the technical problem, the invention provides an embroidery needle suitable for a Hunan embroidery robot. The invention can reduce the pulling force of the embroidery needle on the embroidery thread and provide the positioning mark to facilitate the Hunan embroidery robot to detect the position of the embroidery needle for real-time control.

The technical scheme for solving the technical problems is as follows: an embroidery needle suitable for a Hunan embroidery robot comprises an embroidery needle body, thread guide grooves, needle holes, positioning color rings and a needle point, wherein the needle point is arranged at two ends of the embroidery needle body (4), the thread guide grooves are formed in the embroidery needle body (4), the two needle holes are formed in the center of the thread guide grooves, and a plurality of groups of positioning color rings which are equidistant are arranged on two sides of the embroidery needle body.

In the embroidery needle for the Hunan embroidery robot, the thread guide grooves are arc-shaped and are arranged on two sides of the embroidery needle body.

In the embroidery needle for the Hunan embroidery robot, the positioning color rings are two groups of three color rings with equal intervals and are symmetrically arranged on two sides of the embroidery needle body respectively.

The invention has the technical effects that: the invention has the advantages that the thread guide groove on the embroidery needle can reduce the resistance of the needle in the running process of the needle with thread and simultaneously reduce the pulling force of the needle on the thread in the running process of the needle. The positioning color rings arranged on the two sides of the embroidery needle can facilitate a high-speed camera of the Hunan embroidery robot to acquire the position of the embroidery needle in the whole process of penetrating through embroidery cloth, so that the accuracy of the needle grasping process is improved, the relative position of the embroidery needle and the embroidery cloth can be acquired, and the accurate control of the needle application force of the embroidery needle is realized.

Detailed Description

The invention is described in further detail below with reference to the figures and the specific embodiments.

As shown in fig. 1, 2 and 3, the invention comprises an embroidery needle body 4, a thread guide groove 3, eyelets 1, positioning color rings 2 and a needle point 5, wherein the needle point 5 is arranged at two ends of the embroidery needle body 4, the thread guide groove 3 is arranged on the embroidery needle body 4, the thread guide groove 3 is arc-shaped and is arranged at two sides of the embroidery needle body 4, two eyelets 1 are arranged at the center part of the thread guide groove 3, and a plurality of groups of positioning color rings 2 with equal intervals are arranged at two sides of the embroidery needle body 4. The positioning color rings 2 are two groups of three color rings with equal intervals and are respectively and symmetrically arranged at two ends of the embroidery needle body 4.

The thread guide groove on the embroidery needle body can reduce the resistance of the needle in the running process of the needle with thread and simultaneously reduce the pulling force of the needle on the thread in the running process of the needle. The positioning color rings arranged on the two sides of the embroidery needle can facilitate a high-speed camera of the Hunan embroidery robot to acquire the position of the embroidery needle in the whole process of penetrating through embroidery cloth, so that the accuracy of the needle grasping process is improved, the relative position of the embroidery needle and the embroidery cloth can be acquired, and the accurate control of the needle application force of the embroidery needle is realized.
