Description

Method for improving product processing technology
Technical Field
The invention relates to the field of product process improvement, in particular to an improvement method of a product processing process.
Background
In production, rejects are often produced. Because of the many factors causing the product to be unqualified, it is difficult to determine which factors cause the product to be unqualified, which is not beneficial to the process improvement. Therefore, there is a need for an improved method for processing products to overcome the above difficulties and to improve the processing of products.
Disclosure of Invention
The invention aims to solve the technical problems that the factors causing the product to be unqualified are more, the specific factors causing the product to be unqualified are difficult to confirm, and the improvement of the process is not facilitated, and provides an improvement method of the product processing process.
In order to achieve the purpose, the invention adopts the following technical scheme:
an improved method for processing products, comprising the steps of:
A. determining the position with high product reject ratio, and recording as the position to be improved;
B. determining a process corresponding to a part to be improved, and recording as a problem process;
C. determining a problem procedure with high reject ratio, and recording as a procedure to be improved;
D. and improving the procedure to be improved.
Further, the step A comprises the following steps:
a1: collecting all unqualified products of the previous batch in groups according to the working procedures;
a2: detecting each part of all unqualified products; determining a part with high failure rate, and recording as a part to be improved;
further, the step C comprises the steps of:
c1: respectively collecting all unqualified products of the problem procedure;
c2: respectively detecting the product parts processed by the problem procedures; determining a problem procedure with high reject ratio, and recording as a procedure to be improved;
further, the step D includes the steps of:
d1: determining unqualified phenomena of the process to be improved;
d2: analyzing the existing process problems aiming at the unqualified phenomenon;
d3: aiming at the process problem, the procedure to be improved is improved.
Has the advantages that:
the invention determines the procedure to be improved by systematically detecting the unqualified products, further determines the main factors causing the products to be unqualified, further realizes the improvement of the process and reduces the unqualified products.
Detailed Description
An improved method for processing products, comprising the steps of:
a1: collecting all unqualified products of the previous batch in groups according to the working procedures;
a2: detecting each part of all unqualified products; determining a part with high failure rate, and recording as a part to be improved;
b: determining a process corresponding to a part to be improved, and recording as a problem process;
c1: respectively collecting all unqualified products of the problem procedure;
c2: respectively detecting the product parts processed by the problem procedures; determining a procedure with high reject ratio, and recording as a procedure to be improved;
d1: determining unqualified phenomena of the process to be improved;
d2: analyzing the existing process problems aiming at the unqualified phenomenon;
d3: aiming at the process problem, the procedure to be improved is improved.
Take the process improvement of scaffold product as an example.
Step A1: collecting all unqualified products of the previous batch in groups according to the working procedures;
the total number of unqualified products is 52, and the unqualified products are grouped according to the procedure.
Step A2: detecting each part of all unqualified products; determining a part with high failure rate, and recording as a part to be improved;
the scaffold product was divided into five sections, which were examined. The results showed that the B3 fraction was found to be highly unacceptable and the B3 fraction was the fraction to be improved.
Unqualified part B1 B2 B3 B4 B5 Total number of times
Number of misapprovals 3 1 36 4 8 52
Ratio of 6％ 2％ 69％ 8％ 15％ 100％
And B: the step corresponding to the site B3 is determined.
The procedures related to the part B3 are pipe cutting, punching and welding; these three steps are problematic steps.
Step C1: respectively collecting all unqualified products of the problem procedure;
and collecting unqualified products of the three procedures of pipe cutting, steel seal and welding according to groups, and recording the unqualified products as pipe cutting groups, punching groups and welding groups.
Step C2: respectively detecting the product parts processed by the problem procedures; and determining the process with high reject ratio, and recording as the process to be improved.
Detecting the position corresponding to the pipe cutting process of the pipe cutting group product;
detecting the part corresponding to the steel seal process of the punching group product;
detecting a part corresponding to a welding procedure of a welding group product;
the rejection rate of the punching part is higher, and the punching part is the part to be improved.
Step D1: determining unqualified phenomena of the process to be improved;
the unqualified phenomenon of the punched part is deviated hole.
Procedure (ii) Pipe cutting Punching hole Welding of Total failure of the product
Number of defective products 8 32 12 52
Ratio of 15％ 62％ 23％ 100％
Failure phenomenon Burrs of a ship Eccentric hole Welding offset
Step D2: analyzing the existing process problems aiming at the unqualified phenomenon;
the deviated holes may be caused by inaccurate position of the product during placement and failure of the positioning device;
step D3: aiming at the process problem, the procedure to be improved is improved.
Aiming at the problem of inaccurate position of the product during placement, measures such as adding a limiting device and the like are adopted to improve the process;
and aiming at the problem of failure of the positioning device, measures such as regular maintenance of the positioning device and the like are taken to improve the process.
