Quality appraisal of automatic material distribution equipment

automatic material distribution equipment uses intelligent path planning and multi-machine collaborative control as its core principles. By optimizing navigation and positioning accuracy, transportation efficiency and system fault tolerance, it can achieve accurate material sorting, dynamic obstacle avoidance and multi-task parallel processing. It is widely used in fields such as intelligent warehousing, automobile manufacturing, electronic assembly and pharmaceutical logistics. In e-commerce warehousing, it is used for efficient order response in the "goods-to-person" picking system; in automobile production lines, it meets the demand for on-time distribution of parts; in the pharmaceutical industry, it ensures the sterile and accurate delivery of cold chain drugs. Compared with traditional conveying equipment, automatic material distribution equipment has the characteristics of flexible layout, excellent energy efficiency and digital twin synchronization, and is the core hub of intelligent manufacturing logistics systems.

Zhongke Testing is a product quality appraisal service organization registered with the court. It can provide quality appraisal services for automatic material distribution equipment. It has a professional appraisal team and advanced instruments and equipment to provide fair and accurate appraisal results for the quality appraisal of automatic material distribution equipment.

1. Appearance inspection

conducts a comprehensive inspection of the appearance of the device, including device model, nameplate logo, appearance damage, interface integrity, etc.

2. Functional test

conducts functional tests on the device in actual use environments, including positioning accuracy, receiving sensitivity, data transmission stability, etc.

3. Data analysis

The applicant, an automobile factory, and the respondent, an equipment manufacturer, signed an AGV Distribution System Procurement Contract, agreeing on a positioning accuracy of ±1mm. After the production was put into production, many collisions were stopped due to path deviation. The manufacturer argued that it was caused by the uneven floor of the workshop.

identification analysis results:

The quality analysis expert group discussed and comprehensively analyzed the relevant information of "automatic material distribution equipment", contract technical agreements, on-site inspection case materials and other data, and made the following quality analysis opinions:

The automatic material distribution equipment AGV inertial navigation module gyroscope bias stability involved in the case was >0.5°/h (protocol ≤0.1°/h), and the lidar calibration error was 1.2° (protocol ≤0.5°); the scheduling system task allocation logic was flawed, and the multi-machine avoidance response delay was 0.3s (protocol ≤0.1s).

The appraisal conclusion determined that defects in the navigation system and algorithm were the main cause of the operation failure.

The automatic material distribution equipment quality appraisal report should include:

1, the purpose of the appraisal (such as operational failure attribution, performance verification) and referenced standards (GB/T 20721, ISO 3691-4, etc.);

2, equipment model, software version, operation and maintenance records involved;

3, detection methods and equipment list (such as laser tracker, EMC tester);

4, detection data and failure correlation analysis (such as the impact of gyroscope error on positioning);
