Production method for crossed flocking in camera area of automobile B upper column

Abstract

The invention discloses a production method for crossed flocking of a camera area of an automobile B upper column, which adopts a crossed flocking product, the reflection gloss of the crossed flocking product is 0 no matter from any angle of measurement and analysis, and the requirement that the gloss of the peripheral area of the camera is lower than 0.3 is completely met. A production method for automobile B upper column camera area cross flocking comprises the following steps that (1) the surface of a base material is treated, and low-temperature Plasma is adopted for treatment; (2) flocking glue is sprayed, and a layer of electrostatic flocking glue is sprayed to the surface of the base material; 3) flocking: using a flocking device; the glued base material is placed on a tool table on the lower portion, flocking equipment is started, and cross flocking is started; an angle of 35-75 degrees is formed between the outlet direction of the second down pipe and the flocking area, the second down pipe rotates, and the glue coating surface is flocked at a constant speed by the down flying out of the second down pipe at a certain angle; the method comprises the following steps: firstly, flocking on a base material from an angle, and then flocking at a symmetrical angle, so as to form crossed flocking; and stopping until the base material cannot be exposed in the flocking area.

Description

technical field [0001] The invention belongs to the technical field of flocking, and in particular relates to a production method for cross flocking in the area of ​​a camera head on a pillar of an automobile B. Background technique [0002] The principle of flocking is to use the physical characteristics of same-sex repulsion and opposite-sex attraction to make the fluff negatively charged, and put the object to be flocked under zero potential or grounding conditions, and the fluff is attracted by the plant body with different potential , accelerates to fly vertically to the surface of the object that needs to be flocked. Since the plant body is coated with adhesive, the fluff is vertically stuck to the plant body; [0003] Many parts of the car need to be flocked, such as the center console, armrest box, etc., especially the flocking in the area where the camera is installed on the upper pillar (vertical beam) of the car is required by the recent development of new energy ...

AI Technical Summary

Problems solved by technology

[0004] The surface treated with patterns has been cancelled, due to the limited reduction in gloss, which cannot meet the requirements; the use of specially treated fabric paint can be sprayed on the surface, and the gloss can be reduced to 0.3, but the scratch resistance of the surface is too poor, which makes subsequent processing difficult , and the cost is too high; using conventional electrostatic flocking equipment, there are still deviations when tested at certain angles, and the effect of eliminating gloss cannot be achieved, such as figure 1 ;Because the fluff stands upright on the glued surface, its emission point is on the top surface of the fluff, and the top surface is close to the plane, so that the reflective surface is basically close to the plane, so it will still reflect light when viewed from certain angles;
