Description

technical field [0001] The invention relates to an automatic laminating machine, which belongs to the technical field of semiconductor chip packaging. Background technique [0002] Photosensitive chips such as CMOS Image Sensor (CIS) have been widely used in many fields. For example, an optical mouse used in computer operation, the optical mouse has a light-emitting diode inside, and the light emitted by the light-emitting diode illuminates the bottom surface of the optical mouse, and then part of the light reflected back from the bottom surface of the optical mouse passes through a set of optical lenses , transferred to the micro-imager for imaging. In this way, when the optical mouse moves, its movement track will be recorded as a set of coherent images captured at high speed. Finally, the digital microprocessor inside the optical mouse is used to analyze and process a series of images captured on the moving track. By analyzing the changes in the position of the feature ...

Problems solved by technology

At present, most manufacturers still use manual methods to attach protective labels to the lens surface of the photosensitive chip one by one. The work efficiency is low and the position of the film is not accurate. Labor intensity has also been greatly increased

In order to solve the problem of manual film sticking, some manufacturers also use special automatic film laminating machines to arrange and attach the protective labels on the release film to form a conveying film, and then wrap the conveying film on the conveying film roller. It is necessary to make each protective label Align the lens surface of each photosensitive chip separately, so that the protective label is attached to the lens surface of the photosensitive chip, which can improve work efficiency to a certain extent; but such an automatic film laminating machine is not only complicated in overall structure, high in cost, but also accurate in pasting the film. degree is not high
