Abstract
The invention discloses a focusing-free optical camera module which comprises a lens, an image chip and a lens outer cover. Lens elements are directly connected through adhesive layers in a bonding mode to form the lens. The last surface of the lens is in a panel shape and is integrally glued on the image chip. All the lens elements are adhered together through the adhesive layers to form the lens, and washers are eliminated. On the premise of ensuring high pixel, the height of the focusing-free optical cameral module is reduced. An additional structural area for assembling the lens elements and the washers in a traditional lens is eliminated. The size of the lens is decreased, and the number of focusing-free lens products obtained on one glass wafer is maximized. The cost of the focusing-free lens products is reduced. The last surface of the lens is sheet glass which is directly and tightly glued with protective glass of the image chip together through ultraviolet (UV) glue with several microns and high light transmittance. A traditional space ring or a traditional base is eliminated. The thickness tolerance caused by the space ring is avoided, the focusing-free effects are achieved, and high image quality of the focusing-free optical cameral module is guaranteed.
Description
Technical field
The invention belongs to the optical camera field, be specifically related to a kind of ultrathin type and exempt from the optical camera of focusing.
Background technology
Progressively to new material, high pixel, microminiaturized development, this just orders about traditional design needs further to improve in the development of camera module.
Conventional lenses needed to connect by packing ring between a plurality of eyeglasses in when assembling, and eyeglass for packing ring assembling need to separately to establish a segment structure regional, so just strengthened lens dimension, and then strengthen the module size, not only expend starting material, and be unfavorable for that product is to lightening development.
After having recorded and narrated machinery in patent documentation 1 (the open 201654308U patent gazette of China), Jiao foreshortens in 100 microns; save spacer ring camera lens directly is glued on the cover glass of image chip with glue, reduce with this method that manufacturing tolerance is made the high-quality optical camera module of exempting to focus.but in patent documentation 1, last surface of exempting from the focusing lens group is optical aspherical surface, can not be directly and the cover glass of image chip directly bonding, be used as the position bonding with the image chip cover glass and need to separately establish a segment structure zone beyond the optics effective diameter, so just increased the bore of exempting from focusing lens, make a slice glass wafer (diameter 200mm) upper obtain exempt from focusing lens product decreased number, thereby lifting exempt from the cost of products of focusing lens, and for the whole optical camera module of exempting to focus, exempt from focusing lens and image chip when bonding, only have the neighboring area bonding, and the centre is still separation, it is not very abundant causing bonded areas, product reliability can not optimization.
Summary of the invention
