Automatic film sticking machine

Abstract

The invention relates to an automatic film sticking machine. The automatic film sticking machine is characterized by comprising a feeding assembly and a film pressing assembly, wherein the feeding assembly comprises a feeding bottom plate; the feeding bottom plate is provided with a material filling region; a hoisting machine for driving a material box to hoist is mounted on the feeding bottom plate; a groove for storing a chip framework is formed in an inner wall of the material box; material moving holes are formed in two sides of the chip framework; a discharging hole is formed in one end part of the material filling region, and a material pushing device is mounted at the other end of the material filling region; a film pressing region is provided with a material moving channel and the film pressing assembly; a material moving assembly is mounted one side of the material moving channel; the material moving assembly comprises a sliding material moving platform capable of moving horizontally; a material moving claw capable of hoisting is mounted on the sliding material moving platform; the film pressing assembly comprises a film pressing air cylinder; a stretching-out end of the film pressing air cylinder is connected with a punching rod; an upper pressing block sleeves the punching rod; a lower pressing block is mounted below the upper pressing block; a round cutting edge is arranged on the lower pressing block; and a film belt penetrates through the upper pressing block and the lower pressing block. The film sticking machine provided by the invention can be used for accurately sticking a film and has high working efficiency.

Description

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

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
