Common Issues and Solutions

Lamination Alignment Deviation

Problem Description:Position deviation occurs in the lamination area, resulting in the failure of lamination precision between the product and the functional film (such as OCA/AB adhesive).

Standardized Solution:1. Incoming Material Quality Inspection: - Prioritize checking the incoming material inspection report to confirm that key indicators such as dimensional tolerance, positioning datum, and geometric tolerance of the substrate and functional film are normal, thereby eliminating precision defects of the incoming materials themselves.
2. Precise Alignment Correction: - On the premise of qualified incoming materials, use a 2D image measuring instrument to quantify the offset (including X/Y-axis linear deviation and angular deviation), and precisely adjust the positioning datum of the upper and lower molds based on the measurement results.
3. Closed-Loop Verification and Optimization: - Perform a test lamination after parameter adjustment, and recheck the lamination precision with a 2D image measuring instrument. If deviation still exists, repeat the above measurement-adjustment process until the alignment precision meets the process requirements.

Lamination Bubbles

Problem Description:After lamination, bubble-like appearance defects appear on the product interface, which are divided into two categories: front-end bubbles and middle-rear bubbles according to the location where bubbles are generated.

Front-End Bubble Elimination Solution:- Optimize Process: - Raise the height of the upper suction plate to ensure that a safety gap of 0~2mm is maintained between the front end of the product and the OCA/AB adhesive layer at the initial stage of lamination, avoiding premature air sealing at the front end.

Middle-Rear Bubble Elimination Solution:- Optimize Process: - Lower the height of the lamination roller to ensure uniform pressing force of the roller, providing sufficient channels for air exhaust and avoiding local premature pressing.

Surface Imprint Defects After Lamination

Problem Description:After lamination, indentation and imprint-like appearance defects appear on the product surface, affecting the product's appearance and performance.

Standardized Solution:- Optimize the Lamination Process: - Lower the height of the pressing wheel, strictly control the pressing force of the pressing wheel to avoid excessive pressure. The laminated product can smoothly pass through the pressing wheel with a light manual push and can drive the pressing wheel to rotate smoothly without jamming or hard pressing.

Case Studies

Case Study 1: Manufacturer Benefits from Regular Maintenance

A manufacturing company experienced significant improvements in production efficiency after implementing a regular maintenance schedule for their DGM-500 series machines. By conducting monthly inspections, quarterly check-ups, and annual deep inspections, the company was able to identify and resolve issues early on, reducing downtime by 20% and increasing output by 15%. Regular maintenance also helped in avoiding costly repairs and extending the lifespan of the machines.

Case Study 2: Real-Life Scenarios

A manufacturer noticed that their DGM-1000 series machines were experiencing frequent alignment issues. After implementing a preventive maintenance schedule, they conducted precise alignment corrections and closed-loop verification. This led to a significant reduction in alignment deviations and an overall improvement in lamination quality. The manufacturer also noted that the machines required fewer repairs and were less prone to breakdowns.
