Problems solved by technology

However, how to control it to solve the problem of the uniformity and thickness of the adhesive layer requires a large number of experiments to explore and verify. In the existing automatic gluing process, the control of this link is relatively weak, and the uniformity of the adhesive layer is basically controlled by experience. The uniformity of sex and thickness makes it difficult to control and prone to large errors

Embodiment

[0058] Such as Figure 1-5 As shown, the present embodiment provides a process for automatic coating of sealants by robots on aircraft parts, comprising the following steps:

[0059] Step S1: Gluing robot preparation;

[0060] Step S2: gluing the aircraft parts skin;

[0061] In step S2, determine the theoretical ratio relational expression of the gluing process during gluing:

[0062]

[0063] In formula (1), V L is the linear velocity of the end effector of the robot, V S The moving speed of the push piston for the sealant rubber cartridge, L W is the width of the glue outlet, H 1 For sealant coating thickness, S 1 Push the cross-sectional area of ​​the piston for the rubber cartridge;

[0064] The key parameter configuration of the robot in the automatic coating process of aircraft component sealant is guided according to the theoretical ratio relational expression of the coating process.

[0065] In this embodiment, the theoretical ratio relational expression of...

Abstract

The invention discloses a robot automatic coating process of aircraft component sealant, relates to the technical field of aircraft component sealing technology, comprising the following steps: step S1: preparation of a glue coating robot; step S2: coating of aircraft component skin with glue; step S2 In the process of gluing, determine the theoretical ratio relationship of the gluing process: In the formula, V L is the linear velocity of the end effector of the robot, V S The moving speed of the push piston for the sealant rubber cartridge, L W is the width of the glue outlet, H 1 For sealant coating thickness, S 1 Push the cross-sectional area of ​​the piston for the rubber cartridge; guide the key parameter configuration of the robot in the automatic coating process of the aircraft component sealant according to the theoretical ratio relationship of the glue coating process, the present invention has the advantages of reducing the amount of testing, determining and adjusting The key process parameters can precisely control the advantages of the uniformity of the adhesive layer and the uniformity of thickness.

Description

technical field [0001] The invention relates to the technical field of aircraft component sealing technology, in particular to a robot automatic coating process of aircraft component sealant. Background technique [0002] At present, the current situation of sealant coating for aircraft parts is as follows: ① Operation method: manual coating by workers; The uniformity of the coating is poor, and the uniformity of the thickness of the adhesive layer fluctuates greatly; ③Glue application efficiency: the size of aircraft parts is large, and the accessibility of workers is poor, which in turn affects the application efficiency of sealant; ④Safety risks: for aircraft Where the sealant coating of components is not accessible, workers will step on the components. On the one hand, there is a risk of damaging the structure of the components, and on the other hand, there is a situation of falling redundant objects. [0003] In response to the above problems, automated equipment can b...
