Problems solved by technology
[0003] However, the accuracy of assembly is not easy to control, especially when the lens module uses multiple lenses, aligning the centers of the lenses and coincident optical axes is a critical step
[0004] At the same time, one mold can only produce one kind of lens at a time, which increases the manufacturing cost of the lens module

Embodiment Construction
[0019] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0020] see figure 1 The composite lens 10 provided by the first embodiment of the present invention includes a first lens 102 and a second lens 104 opposite to the first lens 102 .
[0021] Wherein, the first lens 102 has a first optical zone 1021 and a first fixed zone 1022 , and the second lens 104 has a second optical zone 1041 and a second fixed zone 1042 .
[0022] The first lens 102 and the second lens 104 are connected as a whole through the first fixing zone 1022 and the second fixing zone 1042 , and the first optical zone 1021 and the second optical zone 1041 are opposite to each other.
[0023] see figure 2 , the combined lens 20 provided by the second embodiment of the present invention is basically the same as the combined lens 10 , the difference is that the combined lens 20 includes three lenses 201 , 202 and 203 . The three lenses are integ...

The invention discloses a combined lens comprising a first lens and a second lens, wherein, the first lens and the second lens respectively comprise an optic zone and a fixed zone surrounding the optic zone. The combined lens is an integrated whole, the optic zone of the first lens and the optic zone of the second lens are opposite and are provided with gap in between, and the fixed zone of the first lens is connected with the fixed zone of the second lens. The invention also relates to a mould device for manufacturing the combined lens and a manufacturing method. The manufacturing method comprises the following steps: die assembly is carried out on a first mould core and a second mould core, and a first semi-enclosed cavity is formed between the first mould core and the second mould core; according to optical design, at least one mould core is chosen, and is arranged on a first module; the gap between at least one mould core and the first mould core and the second mould core is adjusted; the first module is arranged in the first semi-enclosed cavity; lens molding material is injected into a molding cavity, cooled and demolded to obtain the combined lens.
Description
technical field [0001] The invention relates to an optical element and the manufacture of the optical element, in particular to a composite lens, mold equipment and a manufacturing method for manufacturing the composite lens, and also relates to a lens module using the composite lens. Background technique [0002] At present, lenses are mostly produced in the way of one mold with multiple cavities and injection molding. When assembling a lens module, multiple lenses, lens barrels, spacers, image sensors, etc. are placed on the assembly tray, and then placed in a certain order. It's assembled together. This type of assembly requires great precision. [0003] However, the accuracy of the assembly is not easy to control, especially when the lens module uses multiple lenses, aligning the centers of the lenses and coincident optical axes is a critical step. [0004] At the same time, one mold can only produce one kind of lens at a time, which increases the manufacturing cost of...
