Overview

　　The Guanshentai IVD Kit Automatic Assembly and Leak Testing Machine is an integrated system designed specifically for the automated assembly and seal integrity testing of in vitro diagnostic (IVD) kit components. The equipment combines base card feeding, test strip attachment, top cover snap-fitting and pressing, automatic leak testing, and the discharge of qualified products alongside the automatic rejection of defective ones. The entire line automates the complete process—from bulk components to finished kits—including assembly and airtightness testing. With a production speed of 1,200–2,400 kits per hour, it offers an efficient, high-precision, integrated solution for IVD kit manufacturers.

　　Key Advantages:

　　Integrated Design: Highly integrates assembly and leak testing functions. Efficient process flow is achieved via a synchronous rotary table or a multi-station linear platform, sequentially handling base card positioning, test strip attachment, top cover snap-fitting, press-fastening, airtightness testing, and automatic sorting. This eliminates the need for multiple separate machines, effectively reducing equipment investment and workshop floor space requirements.

　　High-Precision Leak Testing: Utilizes a differential pressure or flow-based airtightness testing system. A preset air pressure is applied to the finished kit's internal cavity, and precision pressure sensors monitor pressure decay. With a detection accuracy of ±0.1 kPa, the system effectively identifies micron-level leaks, ensuring seal integrity and preventing reagent failure due to moisture exposure.

　　Precision Assembly Mechanisms: Base cards and top covers are automatically fed via vibratory bowls or hoppers. Test strips are picked up by vacuum nozzles and precisely placed into designated grooves on the base cards (positional accuracy of ±0.2 mm). Top covers are snapped into place using a servo-driven press system at preset pressures, ensuring a tight fit, uniform gaps, and no misalignment or skewing.

　　Error Prevention and Rejection: Equipped with fiber-optic sensors and pressure-sensing devices, the system provides multiple error-prevention functions, including low-material alarms, detection of missing test strips, and verification of top cover placement. Defective units failing the leak test are automatically ejected into a separate waste bin, ensuring complete separation of qualified and defective products and eliminating the risk of mixed batches.

　　Broad Material Compatibility: Compatible with reagent kit casings made from various plastics such as PP, PS, and ABS. By swapping tracks, fixtures, and press-fitting molds, the system accommodates reagent kits of different specifications and sizes, ensuring rapid and flexible production changeovers.

　　Data Traceability and Management: Features an integrated industrial control system and data storage module that automatically records batch output, defect counts, and testing data. It supports historical data queries and exports, providing traceable evidence for production quality management.

　　User-Friendly Operation: Utilizes a PLC and touchscreen HMI for real-time monitoring of the entire production line. Key parameters—such as pressing force, dwell time, and press-fitting stroke—can be precisely configured; multiple product recipes can be saved and recalled with a single touch during changeovers.

　　Application Scenarios:

　　Widely applicable to automated assembly and leak testing for reagent kits in sectors such as In Vitro Diagnostics (IVD)—including kits for early pregnancy, infectious diseases, drug screening, tumor markers, and cardiac markers—as well as food safety testing (pesticide and veterinary drug residue cards) and animal disease testing (rapid diagnostic cards for pets and livestock). With its efficient, precise, and stable performance, the Guanshentai automated assembly and leak testing machine helps IVD manufacturers achieve a fully integrated, automated upgrade from assembly to leak testing, effectively ensuring product quality and reliability.
