Inspection system and inspection module

An inspection system for inspecting a workpiece, comprising:

• a picking module, comprising a picking fixture, the picking fixture being configured to hold the workpiece;
• a top vision platform, configured to support the workpiece from the picking fixture, wherein the picking fixture is configured to place the workpiece on the top vision platform while the picking fixture is located within a safety zone;
• a top vision module, comprising a top-view camera, the top-view camera being configured to capture a top image of the workpiece carried on the top vision platform from above the workpiece;
• a receiving module, comprising a receiving fixture and a receiving rotation shaft, the receiving fixture being configured to acquire and hold the workpiece from the top vision platform, the receiving rotation shaft being coupled to the receiving fixture and configured to rotate the receiving fixture;
• a bottom vision module, comprising a bottom-view camera, the bottom-view camera being configured to capture a bottom image of the workpiece held by the receiving fixture from below the workpiece;
• and
• a side vision module, comprising a side-view camera, the side-view camera being configured to capture a side image of the workpiece held by the receiving fixture from a side of the workpiece;
• wherein:
• during a period in which the picking fixture places the workpiece on the top vision platform, the picking fixture enters the safety zone and the top vision module is retracted from the safety zone;
• and
• during a period in which the top vision module captures the top image of the workpiece, the top vision module enters the safety zone and the picking fixture is retracted from the safety zone.

• a bottom vision module, comprising a bottom-view camera, the bottom-view camera being configured to capture a bottom image of the workpiece held by the receiving fixture from below the workpiece;
• and
• a side vision module, comprising a pair of side-view cameras;
• wherein the receiving module is configured to:
• place the workpiece held by the receiving fixture between the pair of side-view cameras, allowing the pair of side-view cameras to capture a first pair of side images of the workpiece;
• rotate the workpiece held by the receiving fixture by an angle through the receiving rotation shaft, allowing the pair of side-view cameras to capture a second pair of side images of the workpiece;
• wherein the bottom image is captured simultaneously with the first pair of side images, and/or the bottom image is captured simultaneously with the second pair of side images.
