Description

Automatic station type manual composite material laying workshop

Technical Field

The invention relates to an automatic station type manual composite material laying workshop, and belongs to the technical field of industrial building design.

Background

In the existing workshop for manufacturing the composite material parts, the manual laying process is an essential loop and is a core process for finishing the incremental forming of the appearance of the parts. The traditional station arrangement in the manual laying room adopts a single mould as a center to form a plurality of independent operation stations which are arranged in the manual laying room in a row for production and manufacturing. The conventional process is shown in fig. 1.

In the typical process flow in fig. 1, except the blanking process, the blanking process mainly depends on digital equipment for carrying out accidents, and other processes and material flows among the processes are all completed manually. According to the traditional compatible process layout scheme, the process materials are arranged to be bagged, sealed and combined into a station, and unit production is carried out. Each station needs to be completely configured (comprising a mold parking area, a personnel operation area, a material rack, a workbench, a laser projector, a comprehensive coiled pipe (comprising a vacuum interface and a power socket), an electronic billboard and the like), and because the material rack and the workbench of the traditional station need to store materials required by working for a whole day and need to be configured according to station standards, the occupied area of a single station is large, and the use efficiency of building space is reduced; because the stations are independent of each other, each worker needs to switch the work content at any time on the stations. The effective operation is to lay up layer by layer according to the rules and shapes, and the auxiliary operation also comprises the following steps: transporting materials, arranging materials, checking codes, transporting moulds, preparing moulds, bagging, sealing and the like. The auxiliary or repeated operation is excessive, the labor intensity of workers is increased, the operation complexity is increased, the risk of misoperation is higher, the production rhythm is not controlled, and the influence of the artificial factors of the yield is heavier, so that the production efficiency is reduced.

2. The station adopts a 'back-to-back' station arrangement scheme, the feasibility of combining two stations according to requirements is allowed, and the flexibility of part processing of a production line is realized.

3. Due to the adoption of an informatization means, the production line can more effectively adapt to a customized production mode of C2F (custom function).

4. The station type arrangement enables the manual laying procedure in the composite material forming process to be independent from the auxiliary procedure matched with the station type arrangement, is more suitable for the production line of a 'lightless factory' after the operation of the station type arrangement is replaced by a robot in the future, and the design of the composite material factory can be changed essentially.
