syringe.inspect – Inspection system for syringes in the pharmaceutical and medical technology industries

Piston rod assembly inspection

The correct assembly of the piston rod is a key quality factor in syringe manufacturing. syringe.inspect verifies whether the piston rod is correctly screwed into the stopper and whether the specified screw-in depth is maintained. Deviations can be detected early, and defective syringes can be reliably removed from the production process.

Inspected features:

• Screw-in depth of the piston rod into the stopper
• Correct fit of the piston rod
• Assembly deviations between the piston rod and the stopper

Benefits:

Defective assemblies are detected before subsequent process steps. This reduces follow-up costs and increases process reliability in syringe manufacturing.

LLA flap inspection

For syringes with Luer-Lock adapters, the adapter’s flaps must be complete and undamaged. syringe.inspect visually inspects the flap geometry and detects defects such as damage or breakage.

Inspected features:

• Damage to the LLA wings
• Chips
• Incomplete or deformed wing areas
• Deviations from the target geometry

Benefits:

Defects in the Luer-Lock adapter can impair the syringe’s function. The LLA wing inspection enhances safety in the assembly process and improves quality assurance prior to further processing.

Luer-Lock adapter inspection

The Luer-Lock adapter is a key connection point on the syringe. syringe.inspect inspects the adapter for correct assembly, orientation, and potential damage. This allows for the early detection of assembly errors and defective components.

Inspected features:

• Correct assembly of the Luer-Lock adapter
• Orientation of the Luer-Lock adapter
• Cracks in the Luer-Lock adapter
• Damage to the wings and connection geometry
• Defective or incomplete components

Benefits:

The inspection helps reliably detect function-critical defects in the syringe’s connection area and specifically weed out defective parts.

Silicone coating inspection

The silicone coating on the inner surface of a syringe affects the syringe’s function and performance characteristics. syringe.inspect checks whether the silicone coating is present and evenly applied. Additionally, it can detect anomalies such as streaks or droplets.

Inspected characteristics:

• Presence of silicone coating
• Uniformity of coating
• Streaking
• Droplet formation
• Uneven distribution on the inner surface of the syringe

Benefits:

Reliable inspection of the silicone coating ensures consistent syringe quality and helps detect deviations in the production process at an early stage.

Syringe tip assembly inspection

The syringe tip must be correctly assembled and present in its entirety. syringe.inspect checks the fit and presence of the syringe tip as part of automated quality control. The inspection can be used, in particular, prior to the packaging process.

Inspected characteristics:

• Presence of the syringe tip
• Correct fit
• Assembly defects
• Deviations prior to packaging

Benefits:

Missing or incorrectly assembled syringe tips are reliably detected. This prevents incomplete products from entering the packaging.

Count verification in the syringe nest or tray

During the packaging process, syringe.inspect verifies that the correct number of syringes is present in the syringe nest or tray. Missing syringes or incorrectly filled positions can be automatically detected.

Inspected characteristics:

• correct number of syringes per syringe nest
• completeness in the tray
• empty or incorrectly filled positions
• deviations in the packaging process

Benefits:

The completeness check prevents incomplete packaging units and increases safety prior to shipment or further processing.
