Spray hanger attitude laser detector

Abstract

The invention discloses a spraying hanger attitude laser detector. The spraying hanger attitude laser detector comprises a testing frame, a spraying hanger and an electric cabinet component, wherein spraying workpieces needed to be sprayed are placed on the front of the spraying hanger and correspond to the positions of spray guns of a spraying robot; the testing frame is arranged on the back of the spraying hanger; and six laser sensors corresponding to the position of the spraying hanger are arranged on the testing frame. The laser sensors are used for detecting the attitude of the sprayinghanger, which is a non-contact measurement method; the spraying hanger attitude laser detector has fast detection speed and good data repeatability; compared with existing manners of using the robot for point-to-point and using a laser level meter for paying-off, the spraying hanger attitude laser detector has the advantages of no manual intervention or no manual adjustment of location, no manualjudgment of the degree of deviation and the like.

Description

technical field [0001] The invention relates to the field of spraying equipment, in particular to a spraying hanger attitude laser detector. Background technique [0002] Such as figure 1 As shown, the existing situation is that on the robot spraying line, the spraying workpiece 10 is hung on the spraying fixture, and then the spraying fixture is hung on the spraying bracket 10, and several spraying brackets 10 are driven by the conveyor chain and connected end to end. A closed-loop transmission system is formed. When the spraying bracket 10 passes through the robot 8 in sequence, the robot 8 uses the spray gun 9 to spray the workpiece 10. [0003] During the cyclic use of the spraying bracket, the paint layer on the surface becomes thicker and thicker. It must be removed regularly, transported to a designated cleaning unit, and removed by chemical or high temperature methods, and then transported back to the spraying line for reuse. Usually, two groups of spraying bracket...

Causes sprayed parts to fall or poor surface

When the posture of the spraying hanger changes, the relative distance and angle between the spraying part and the spray gun will change, resulting in spraying defects such as sagging and orange peel, seriously reducing product quality, causing batch scrapping, and wasting paint and materials

[0005] At present, there is no high-efficiency laser detection instrument or method for the attitude of spraying racks. It can only rely on placing a laser level to manually judge the degree of skew, and use this as a benchmark to correct it, which is time-consuming and laborious, and the repeatability is poor.

And without objective data, further analysis is impossible; the spraying production line needs regular inspection and correction, which greatly reduces the operating rate of the spraying line, and the success rate of inspection and correction is low, the rework rate is high, and the effect cannot be determined after correction
