Abstract
The utility model 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
The utility model relates to a kind of Dui Zhen mechanism, mainly in order to point gum machine, changes detection and the correction of needle position after syringe needle.
Background technology
Point gum machine claims again glue spreader, adhesive dripping machine, adhesive supplier etc., that special convection cell is controlled, and by fluid drop, be coated on the automatic machinery of product surface or interiors of products, can realize three-dimensional, four-dimensional path point glue, can be in product surface, outer wall, vertical plane, gap, sphere curved surface gets ready fast, setting-out, picture circle and various irregular figures.Therefore, point gum machine has been widely used on various electronic products.
Point gum machine drip a plastic pin mouth be syringe needle in use, can there are wearing and tearing or damage, for guarantee point colloid amount, also need regularly syringe needle checked or change in addition, and the syringe needle of point gum machine is generally less, electronic product is harsher to a glue status requirement simultaneously, therefore whether the position of syringe needle will put in place and can only lean at present artificial naked eyes to observe syringe needle installation to a glue precision and quality important, and whether the installation after the replacing of very difficult precisely control syringe needle is accurate.
Summary of the invention
Whether, in order to overcome above-mentioned defect, the utility model provides a kind of Dui Zhen mechanism, can automatic decision point gum machine syringe needle installation site accurate.
The utility model for the technical scheme that solves its technical problem and adopt is: a kind of Dui Zhen mechanism, comprise base and be placed in CCD on this base, light source, No. two light sources and prism, a described light source is over against the camera lens setting of described CCD, described No. two light sources provide light source for described prism, and the incidence angle along the light of the camera lens of described CCD to described prism is acute angle.
As further improvement of the utility model, the cross section of described prism is isosceles right triangle.
As further improvement of the utility model, the angle of described No. two light sources and described CCD camera lens place direction is 20 degree.
As further improvement of the utility model, on described base, be installed with CCD holder, this CCD holder is provided with U-lag, and can slide and be positioned in this U-lag in the bottom surface of described CCD.
As further improvement of the utility model, described No. two light sources are fixed on described base by light source holder.
As further improvement of the utility model, described prism is fixed on described base by prism holder.
As further improvement of the utility model, four side at described base is respectively equipped with front shroud, back shroud, left side cover plate and right side cover plate, the top of this front shroud, back shroud, left side cover plate and right side cover plate is provided with upper cover plate, described upper cover plate, front shroud, left side cover plate, right side cover plate and back shroud and described base are connected to form one described CCD, light source, No. two light sources and prism is coated in it, be provided with to detect and insert hole with syringe needle on described upper cover plate.
The beneficial effects of the utility model are: Gai Dui pin mechanism is by X, Y, the Z position of CCD vision system test point needle head, when syringe needle enters CCD within sweep of the eye time, light source and CCD judge the X of syringe needle, the position of Z axis, No. two light source is judged the Y-axis position of syringe needle by speculum and CCD, thereby position that can comprehensive detection syringe needle, be convenient to adjust in time when deviation appears in needle position, according to this guarantee point glue precision.
