Abstract

The invention discloses an injector needle back-stitching detection method and device, and aims to provide an injector needle back-stitching detection method and device which are fast in detection speed and high in accuracy rate. In the technical scheme, a reflective quantity of a needle top is used to judge whether a back-stitching situation exists. When a tool clamp strip equipped with the injector needle is transferred to a detection station by a conveyor belt, a light emitter emits light to the detection station, and a light receiver detects light intensity of received light and transmits the light intensity to a control module; the control module detects the light intensity and compares the light intensity with a threshold; if the light intensity is more than the threshold, the needle at the current detection station is judged to be back-stitching; if the light intensity is smaller than the threshold, the needle is judged to be normal; and then a light-emitting diode is used for displaying and a needle unloading mechanism is used to unload a back-stitching needle. In the invention, the injector needle can be detected quickly, efficiently and accurately; the low cost and highly practical performance are realized; the product factory qualified rate can be effectively guaranteed; and the method and device of the invention can be applicable to all the injector needle manufacturers.

Description

technical field [0001] The invention relates to the technical field of fast detection by using a light reflection system, in particular to a method and a device for detecting the back needle of a syringe needle by using a light reflection system. Background technique [0002] In the syringe production line, it is necessary to carry out online detection of whether the needle is reversed. In the prior art, most of the online detection of the needle backwards is manually performed, and some of them are detected by image recognition technology. Manual inspection Set up a manual inspection station next to the production line, and completely rely on people to complete the detection of whether the product has back stitches. Image recognition requires multiple expensive high-definition cameras and complex computer systems. [0003] The main disadvantages of manual inspection are: the working environment of workers is harsh and the labor intensity is high; inspectors who observe movi...
