1) Do quality inspection of the "three hearts", "three diligence", "three no":
1. Three hearts: concentration, meditation and patience.
2. Three services: leg work, hand work, and mouth work.
3. Three nos: do not accept bad, do not make bad, and do not deliver bad.
2) Basis of quality inspection.
1. Inspection: Through observation and judgment, the conformity evaluation is carried out in combination with measurement and test when appropriate.
Quality inspection: a technical inspection activity that observes, measures, and tests one or more quality characteristics of a product, and compares the results with the specified quality requirements to determine the qualification of each quality characteristic.
2. Quality inspection basis: relevant laws and regulations, technical requirements and technical documents, contracts and processing agreements, etc.
3. The main functions of quality inspection: identification, checking, prevention and reporting.
Identification: Determine whether the product meets the requirements.
Check: no production, no reproduction, no release, no delivery.
4. Quality inspection steps.
Inspection Preparation Familiarize yourself with the requirements of the regulations. Determine the inspection method. Translation into technical documents (regulations, instructions);Measurement or test (equipment is normal, data is valid);
Record;Compare and judge;
Identification and disposition.
3) Different categories of product quality inspection.
1. Quality inspection of mechanical products.
Features: Parts are the basic units Mechanical products are composed of several units (parts) and are organically collected. The mechanical machine products are divided into two parts: fixed parts and moving parts.
The main technical performance characteristics.
Parts: chemical composition, microstructure, structural size, geometric parameters, shape and position tolerance, surface roughness, mechanical and mechanical properties, special requirements.
Components and Integrals: Flexibility of moving parts, firmness of fixed parts, interchangeability of mating parts, specifications and dimensions, etc.
Inspection and test methods for mechanical parts.
Chemical analysis, physical tests (mechanical properties, non-destructive testing, metallographic structure, geometric measurements).
Product performance test: function, structure, idling, load, human adaptability, safety, reliability, etc.
2. Electrical and electronic product quality inspection.
Features: Must use electrical energy Electrical insulation Circuit forms the core part A large number of insulation, conductive, magnetic and basic components are used Affected by environmental conditions.
The main content and method of inspection.
Type test (assessment of design conformity): structural requirements and performance requirements.
Routine test (to assess the conformity of batch products).
Sampling trials and investigational trials.
The inspection content of electrical products includes two parts: structural requirements and performance requirements.
4) Quality inspection agency.
1. Nature of quality inspection department:
It is an important part of QMS and independently exercises inspection authority.
Internally: quality control. Outside the organization: Provide evidence of product quality qualifications.
2. Status of quality inspection department:
Within the organization: the highest level is directly supervised, and the independent exercise of inspection authority is authorized. It is important to have an important responsibility for the products to fully meet the standard requirements. The results of the inspection are judged without any interference from the production organization or other departments.
Outside the organization: On behalf of the production organization, we provide product quality evidence to customers, consumers, and society, and the work is protected by law.
