Customer has issues:

On the engine assembly line, certain precision components (such as connecting rod bolts, valve springs, gasket sleeves, etc.) are assembled in multiple pieces and packed in special boxes or packaging boxes in fixed quantities before being sent to downstream assembly plants. In the past, in the high-speed packaging process, manual visual inspection or counting guns were mainly relied on for quantity verification. However, due to factors such as fatigue from continuous operations, small part sizes, and packaging visual blind spots, occasional missing parts problems were difficult to solve. Once the missing parts box flows into the customer's production line, it will cause engine assembly interruptions, line shutdowns for inspection, and may even lead to quality hazards due to incomplete parts, causing significant economic losses and reputation damage.

Solution: Integrated dynamic weight sorting system

To address this pain point, "Jinggong Power" has introduced a high-precision dynamic weight sorting scale system at the end of its key component packaging line. The core logic of this solution is to transform "quantity detection" into a more reliable and automated "weight detection".

Online high-speed detection and judgment: The packaged material box passes through the dynamic weighing platform at a constant speed and smoothly through the conveyor line. The precision sensors and high-speed processors inside the weighing platform can instantly capture the net weight of the material box during its movement (the system automatically removes the skin and deducts the known box weight). Real time comparison of weight data with preset standard values and tolerance zones.

Automatic sorting and exception handling:

Qualified products: Boxes with weight falling within the tolerance zone are determined by the system to have an accurate quantity and seamlessly transported to the next stage for palletizing and shipping.

Suspicious product: Once the weight is significantly lower than the standard value (deviation greater than 50% of the weight of a single part), the system will immediately determine it as a "suspected missing part". At this point, the sorting scale will trigger the downstream pneumatic push rod or steering device to automatically remove the material box from the main conveyor line and transfer it to an independent "re inspection station".

Re inspection and traceability: At the re inspection station, the operator opens the box for manual final confirmation. The system will record the ID, time, and weight deviation data of the abnormal box, and can be associated with the production batch for root cause analysis, tracing whether it is a malfunction in the feeding system, a missed grab by the robotic arm, or a problem in other links.
