Description

Technical Field

[0001] The utility model belongs to the technical field of camera lens assembly equipment for electronic communication devices, and particularly relates to a mylar sheet flipping and assembling machine. Background Art

[0002] On existing communication and entertainment devices such as mobile phones, tablet computers, and smart watches, cameras are provided. Such components need to use mylar sheets for outer sealing or protection. This type of mylar sheet is made of polymer material, with a relatively thin and small volume. During assembly, it is first temporarily stored through a quantitative placement device, and then the mylar sheet is extracted through a negative pressure suction device. After extraction, the mylar sheet is placed on the lens.

[0003] The technical problems encountered in the prior art are:

[0004] Due to the thinness of the mylar sheet, during assembly, if the mylar sheets are offset and stacked, repeated picking of the mylar sheet often occurs, that is, one negative pressure tube adsorbs two or more stacked mylar sheets, resulting in two or more sheets being attached to the lens, causing problems in the lens area and affecting subsequent assembly.

[0005] In view of the above problems in the lens assembly process, the technical problem that needs to be urgently solved by those skilled in the art is to design a mylar sheet flipping and assembling machine that can achieve single-piece selection of the mylar sheet during assembly and avoid the stacking of more than two mylar sheets on the lens. Summary of the Invention

[0006] In view of the above-mentioned disadvantages of the prior art, the purpose of the present utility model is to provide a mylar sheet flipping and assembling machine, which is provided with a negative pressure flipping table on the workbench.
