Vision for tray inspection
optics
Points to watch
- Lidding film: transparency, non-flatness, glossiness. Characteristics that require specific lighting.
- Tray: sometimes tilted. Some defects are not visible from the top view.
- Contents: variable color. The arrival of a new color, very different from previous ones, will require a training phase.
integration
Station integration
- After the tray has been filled and sealed. Top view with low-angle lighting for defects on the lidding film.
- 360° side view with 4 cameras for defects on the tray body.
- Make sure the lighting height can be adjusted and the camera moved if the station has to handle very different tray heights.
- Inspection of multiple defects, at a rate of 10 products per second, with Psycle Assistant Production (PAP).

Foreign body detection
Psycle machine vision systems detect metal, plastic or bone fragments in real time on your food production lines, before they reach the consumer or damage your equipment.

Leak detection on pouches
Pressure, deformation, fill level: machine vision detects leaks and sealing defects on food pouches at the end of the line, to reject non-compliant units before packaging and protect product traceability.

Go to the FAQSealed trayWhat lidding defects does vision detect on a tray?
It detects product in the seal, seal defects and channel leaks, among others. These defects are numerous and varied: the AI learns from the specific characteristics of each one rather than applying a single threshold.
Sealed trayCan a seal defect be detected before it causes a leak?
Yes. A poorly sealed lid is visible in the image as soon as it leaves the tray sealer, before it shows up in a leak test or at the customer's site. Every tray is inspected at line speed, not just a sample.
Sealed trayDoes vision detect a foreign body under the lidding film?
Yes, under the lidding film as well as on the surface of the product. A foreign body can be recognized by a different shade or shape, which lighting reveals down to four hundredths of a millimeter. Detection remains limited to visible bodies: what is detectable on your products is confirmed during the feasibility study.
Sealed trayHow can a defect on the wall of a tray be spotted?
Marks, dents and clouding stand out when the lighting sweeps across the tray wall. The optical setup is therefore designed to bring out these surface features rather than simply illuminate the part.
Sealed trayCan product outside the tray be detected?
Yes, it is a filling defect. The system must recognize the different planes of the image to distinguish product that overflows from product that is properly inside the tray. It learns this difference from images of your production.
Sealed trayCan a single station handle multiple tray formats and designs?
Yes, that is one of the goals of the solution: inspecting a wide variety of formats and designs at high speed with minimal camera adjustments. The model learns what is normal for each product reference, and your teams can add a new one using the PAQ quality platform.
