Needle aligning mechanism

Abstract

The invention discloses a needle aligning mechanism. The needle aligning mechanism comprises a base, and a CCD (charge coupled device), a first light source, a second light source and a prism which are arranged on the base; the first light source is over against a camera of the CCD; the second light source provides a light source for the prism; the incident angle of light rays along the camera of the CCD to the prism is an acute angle. The needle aligning mechanism detects the X, Y and Z positions of a dispensing needle by a CCD visual system, when the needle enters the CCD view range, the first light source and the CCD judge the X and Z axis positions of the needle, and the second light source judges the Y axis position of the needle by a reflection mirror and the CCD, so the position of the needle can be detected in an omnibearing mode, the position of the needle can be conveniently adjusted in time when the needle is deviated, and the dispensing precision is ensured.

Description

technical field [0001] The invention relates to a needle alignment mechanism, which is mainly used for detecting and correcting the position of the needle after the needle is replaced by a dispensing machine. Background technique [0002] Dispensing machine, also known as gluing machine, dispensing machine, gluing machine, etc., is an automatic machine that controls the fluid, and applies the fluid to the surface of the product or inside the product. It can realize three-dimensional and four-dimensional path dispensing , can quickly dot, draw lines, draw circles and various irregular figures on the surface of the product, the outer wall, the vertical surface, the gap, and the spherical surface. Therefore, glue dispensers have been widely used in various electronic products. [0003] The dispensing needle of the dispensing machine, that is, the needle, will be worn or damaged during use. In addition, to ensure the quality of the dispensing, the needle needs to be checked or ...

Problems solved by technology

[0003] The dispensing needle of the dispensing machine, that is, the needle, will be worn or damaged during use. In addition, to ensure the quality of the dispensing, the needle needs to be checked or replaced regularly, and the needle of the dispensing machine is generally small. At the same time, electronic products The requirements for the dispensing position are relatively strict, so the position of the needle will have an important impact on the accuracy and quality of the dispensing. At present, it is only possible to observe whether the needle is installed in place with the naked eye, and it is difficult to accurately control whether the installation of the needle is accurate after replacement.
