Chip inspection system

Background introduction

In the line production process, the manipulator grabs 8 chips each time and accurately sticks them to the circuit board. The chips in the material tray may be placed on the reverse side due to manual reasons, or there are no products in the fixed grasping position, or even product defects. It is precisely because of these reasons that the finished products are unqualified, so the material tray is placed and needs to be carefully confirmed by manual. Correct before placing on the manipulator grasping platform. However, people always have the phenomenon of fatigue work, the appearance of the product is small, there are many missed inspections, and the production efficiency is low.






System performance

The Cognex In-Sight 7050 intelligent vision system, combined with the motion control system, can automatically identify the incoming product information In the 8 areas fixed by the manipulator, and accurately, stably and efficiently judge whether the product in the corresponding position exists, whether it is inverted, and whether it is defective. When the product is defective or reversed, the system sends a NG signal, the grasping manipulator will not grasp the product, the plate moving platform will automatically skip, the next cycle of 8 pieces of product moved to a fixed position If the product is NG, the manipulator will not grasp. If OK, the manipulator will grasp the action.

Detect whether the product in the material tray adopts the pattern matching principle;

The principle of area calculation is used to detect whether the product in the tray is inverted or whether the product is defective.

The missed detection rate is 0%.

Accuracy: 100%.

Detection method: automatic production line in motion detection

Working effect

The visual inspection system stably and efficiently detects unqualified information without affecting the production efficiency, solves the customer's on-site problems well, saves the labor cost and reduces the waste of raw materials.

Application field

Electronics, medicine and food.
