Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention involves the flow of a plurality of products with different work process orders and contents, and the flow of information such as work conditions that are appropriately determined based on the work history up to that point. The present invention relates to a work progress instruction method and device suitable for improving production efficiency, work reliability, and quality in a production line.

[Background of the invention]

Various work progress/in-progress display devices have been developed and put into practice, but most of them are just in-progress display boards that display the amount of material and production amount for each work process that has been categorized in advance. . However, in the case of semiconductor manufacturing processes, for example, multiple types of manufacturing equipment are generally used in the required types, and the same type of equipment is installed in the required number and is repeatedly used in multiple work processes for multiple products. Because of this, there is a high likelihood of work waiting due to mechanical interference, and unless appropriate instructions are given as to which product and which work process should be performed with which equipment with priority, unnecessary stagnation or shortage of semi-finished products will occur. Moreover, even for the same type of product, the same work process, or the same equipment, the work conditions for each production unit may differ partially depending on the work results up to the previous work process, so the priority of work for each production unit In some cases, unnecessary setup work may be more likely to occur. In addition, with conventional work-in-progress display boards, there is no means to display the work status of each production unit in each work process or device (9 completed out of 9 unstarted tasks) or to record 2 the results of work in each production unit. Not only will setups be made due to inappropriate start instructions, but there is also the risk of delays in appropriately changing work conditions in consideration of previous work history, resulting in a high number of defective products and poor quality. It must also be taken into consideration that this may cause a decrease in

In addition, the progress and work-in-progress status of each production unit is managed by dividing the production unit itself using storage equipment installed in each work process (Japanese Patent Laid-Open No. 55-16170).
1 Publication), but even in this case, it is impossible to ensure quality unless you have an overview of the progress status and work results (number of good products, number of defective products, quality level) of each production unit for each product, work process, and equipment used in the entire production line. Not only will supervisors be delayed in giving instructions to change work conditions and equipment used, but it will also be difficult to optimally control work processes based on previous work results.

In addition, in the conventional work instruction method, for each production unit,
Since this is a method of instructing which work process is to be completed and by when, a worker or automatic device selects the desired production unit from the work in progress for that work process and assigns it to that production unit. From the attached work progress sheet (all work processes and their technical sequence), identify the work process to be performed this time, and also check the work conditions and equipment operating procedures corresponding to this work process in the work attached to each piece of equipment. It is necessary to proceed with the work by reading from the instruction sheet (in which standard conditions are filled in in advance). For this reason, it is important not only to reduce work efficiency or cause incorrect work due to misreading, but also to give optimal work instructions based on previous work results and taking into account the unique habits of the equipment and the worker. It was difficult.

As described above, although the conventional methods and devices are still in practical use, there is still considerable room for improvement.

[Purpose of the invention]

In view of these circumstances, an object of the present invention is to improve the production efficiency of the entire line in a production line in which the same type of equipment is repeatedly used in multiple work processes for multiple products, and in which work conditions need to be changed for each production unit. By providing an overview of unit work results and work progress status, it is possible to eliminate stagnation and shortages of unnecessary items and improve production efficiency, as well as to automate the setting of appropriate work conditions and instructions, and eliminate defects. An object of the present invention is to provide a work progress instruction method and its device that realize quality improvement.
