Problems solved by technology

However, based on the traditional NC program operation control method, it only includes the laying path and the connecting path. For laying problems, the positioning and relaying of defective tows can only be manually intervened, manually stop and run to the starting point of laying defective tows laying, or directly relying on the equipment itself to automatically run to the starting point of laying the defective tow for relaying, which not only increases the difficulty of the equipment operator, reduces the laying efficiency, but also greatly increases the operation risk of the equipment, and cannot Adapt to the characteristics of automatic wire laying

Embodiment approach

[0035] This embodiment discloses an automatic silk laying program operation control method, as a basic implementation of the present invention, comprising the following steps:

[0036] Step S1: Plan the automatic wire laying trajectory of the composite material, and generate several strips 5 for each layer, such as figure 2 As shown, four strips 5 are set, and each strip 5 includes the laying path 1 that must be passed by the automatic wire laying equipment to complete the laying of the strip 5;

[0037] Step S2: Establish the relative positional relationship between the laying model and the automatic laying equipment model, and set a fixed point in the equipment coordinate system as the safe laying point 6;

[0038] Step S3: For each strip 5, generate three non-interfering motion paths;

[0039] Step S4: NC program is set based on the laying path 1 in step S1, the laying safety parking point 6 in step S2 and the motion path in step S3;

[0040] Step S5: Carry out automatic...

Embodiment 2

[0043]This embodiment discloses an automatic silk laying program operation control method, as a preferred embodiment of the present invention, that is, in Example 1, the laying and laying safety mooring point 6 is far away from the laying model to ensure that the automatic silk laying equipment There is no interference between the laying safety berth point 6 and the laying model when it moves; in step S3, the three non-interfering motion paths are respectively: the outbound path 2, the laying safety berth point 6 to the starting point of laying path 1 return path 4, the movement path between the end point of laying path 1 and the laying safety berth point 6; transition path, the path between the end point of the current strip 5 laying path 1 and the starting point of the next strip 5 laying path 1 connection path, such as figure 2 shown.

[0044] Further, in step S4, the setting of the NC program includes setting the wire laying program, and setting the wire laying program i...

Embodiment 3

[0054] This embodiment discloses a method for controlling the operation of an automatic wire laying program. As a preferred embodiment of the present invention, that is, in Example 2, setting the NC program also includes setting a fault reset program, and setting the fault reset program includes the following steps:

[0055] Step S42-1, edit the NC code based on laying the safe parking point 6 and the motion path, including jumping to the logical control code of the return path 4, the strip 5 return path 4 program segment code and the interrupt program code;

[0056] Step S42-2, based on the NC code, setting the start mark of the program segment of the strip 5 return path 4.

[0057] Further, in step S5, the automatic wire laying part placement based on the NC program includes: starting the wire laying program, and judging in real time whether there is a wire laying fault during the running of the wire laying program, including the blockage detected by the equipment If there i...

Abstract

The invention belongs to the technical field of prepreg tow automatic laying forming and particularly relates to an automatic tow laying program operation control method. The method comprises steps that an automatic composite material tow laying track is planned, a plurality of strips are generated for each laying layer, and each strip comprises a laying path through which automatic tow laying equipment must pass to complete strip laying; a relative position relation between the laying model and the automatic fiber laying equipment model is established, and a fixed point under an equipment coordinate system is set as a laying safety mooring point; for each strip, three motion paths without mutual interference are respectively generated; and an NC program is set, and automatic fiber placement parts are laid in the NC program. Compared with the prior art, according to the method, safe and automatic returning to a laying safety mooring point is achieved, then functions of automatic fiber laying problem automatic returning, rapid re-laying and the like are achieved, laying efficiency is improved, the manual participation amount in the laying process is further reduced, and the equipment operation risk is reduced.

Description

technical field [0001] The invention belongs to the technical field of automatic laying and forming of prepreg tow, and in particular relates to an automatic laying program operation control method. Background technique [0002] With the rapid development of composite material technology and its processing technology and inspection and maintenance technology, the amount of composite materials used in military and civilian aircraft is increasing significantly. The automatic production process of composite materials represented by automatic tape laying and tow laying has greatly improved. Application of composite materials in aircraft structures. The automatic laying technology uses a multi-axis linkage laying head to bundle multiple bundles of prepreg tows into a variable-width prepreg according to the path planned by the process through the functions of feeding, heating, laying, compacting, cutting, and restarting. The technique of laying down the tape after dipping it on t...
