Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of sheet electronic component detection, in particular to a detection device for multi-layer laminated sheet electronic components. BACKGROUND

[0002] Sheet electronic components come in a variety of types. Some sheet electronic components have very thin films that need to be laminated together for bonding. The bonding insulating layer, protective layer sheet electronic component layer, and multi-layer sheet electronic component also need to be bonded before cutting and then used after cutting.

[0003] Such laminated and cut sheet electronic components are laminated and bonded together layer by layer as a whole. During lamination, the laminated sheet electronic components may be misaligned, causing the upper and lower layers of the laminated sheet electronic components to be skewed. The sheet electronic components also need to be pressed and bonded. During the pressing process, the originally laminated sheet electronic components may also have a certain inclination angle. If there is an inclination angle, the internal circuit and various insulating and protective patches of the sheet electronic components cannot operate optimally, and various uncontrollable situations may occur during operation, so the sheet electronic components cannot be used as good products and need to be recycled.

[0004] The inclination and deviation are very small and cannot be identified by the naked eye. The deviation is in microns, so it can only be detected by special equipment and requires high-precision focusing.
