Insertion machine quality appraisal

insertion machine is the core equipment in the field of electronic manufacturing. It realizes high-speed and high-precision insertion of electronic components (such as resistors, capacitors, and connectors) through automated mechanical systems. The insertion machine can complete the mixed installation of surface mount (SMD) and through-hole (THT) components in mobile phones and computer motherboards, with a placement accuracy of ±0.05mm; handle high-density insertion of vehicle sensors and control modules (such as the miniaturization insertion requirements of Tesla's battery management system); complete the sterile insertion of precision components such as pacemakers and ultrasound probes.

Compared with traditional manual operation, modern insertion machines can increase production efficiency by more than 80% with full-process digital control, multi-axis linkage collaboration and real-time defect detection capabilities. They are key equipment for the intelligent upgrading of the electronics industry and directly affect product reliability and corporate market competitiveness.

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

With the miniaturization and production scale-up of electronic components, inserter machine quality disputes occur frequently. The judicial dispute focuses on:

1, disputes over accuracy indicators: such as whether the component mounting position deviation meets the standard, whether the pad damage rate exceeds the limit;

2, material and process defects: degradation of the material of the robotic arm, Failure of guide rail lubrication leads to wear;

3. Failure of the control system: misjudgment of the visual recognition algorithm and lack of suction nozzle pressure adjustment function;

4. Contract performance issues: the delivered equipment does not match the technical agreement.

insertion machine quality identification technical methods include:

1, material performance testing

using a spectrometer to detect the material of the robotic arm and verifying the heat treatment process; detecting internal defects in the guide rail weld through ultrasonic flaw detection, and measuring the Ra value of the sliding surface with a surface roughness meter.

2, geometric accuracy verification

The laser interferometer measures the positioning accuracy and repeatability accuracy of the robotic arm; the three-coordinate measures the coaxiality between the center of the nozzle and the PCB pad.

0 Scanning electron microscope (SEM) was used to observe the damage morphology of the pad, and energy dispersive spectrometer (EDS) was used to detect the composition of the pad coating; the dynamic response of the robotic arm was analyzed based on finite element simulation, and the acceleration and deceleration parameters were optimized.

An electronics factory of the applicant signed a "High-speed Insertion Machine Purchase Contract" with an automation equipment company of the respondent, agreeing to purchase 5 pieces of equipment with model IP-2000 for 5G communication board insertion. After being put into production, the component mounting position deviation reached ±0.08mm, and the pad damage rate exceeded 0.5% (standard ≤0.1%), resulting in customer returns. The electronics factory believed that the equipment had design defects and demanded compensation for losses. The equipment company argued that the problem stemmed from improper operation, and both parties went to court.

Identification analysis results:

The quality analysis expert group discussed and comprehensively analyzed the relevant information of the "insertion machine", contract technical agreements, on-site investigation case materials and other data, and made the following quality analysis opinions:

1. The material of the mechanical arm of the insertion machine involved is ordinary aluminum alloy, and the yield strength is only 200MPa, resulting in deformation; the guide rail grease grade is inconsistent, and the wear amount reaches 0.1mm/thousand hours.

2, the mechanical arm transmission chain of the insertion machine involved in the case has insufficient stiffness, and the vibration amplitude reaches 0.05mm (standard ≤0.02mm) during insertion; the visual light source is not equipped with a diffuse reflective plate, and the failure rate of identifying reflective elements (such as tantalum capacitors) exceeds 5%.

insertion machine quality appraisal report should include the following content:

1. The purpose and basis of the appraisal.

2. Model, specification, manufacturer and other information of the equipment being identified.

3. Identification method.

4. Identification results (including whether there are quality problems, causes of problems, etc.).
