Description
Technical field
The present invention relates to a kind of camera lens module and assemble method thereof.
Background technology
Compare with general optical instrument, the structure of camera lens is comparatively complicated, often is comprised of a considerable amount of eyeglass.When optical design, the relative position of these eyeglasses all is used as complete ideal situation and is designed, namely, picture element during design is to finish under the ideal conditions that overlaps fully of the optical axis at every eyeglass, every eyeglass does not exist with one heart with footpath degree error, and, also ignored the trueness error of lens barrel in the machine-building process, think that the setting of the relative position of every eyeglass in lens barrel also is absolute accurate.
But in view of the restriction of manufacturing technology, its optical axis all can have in various degree inclination or deviation when every eyeglass was packed lens barrel into, thereby produced concentric together footpath degree error, and this will inevitably affect the image quality of assembling rear lens.And because the lens barrel manufacturing accuracy is limit, eyeglass mutual spacing in vertical direction also exists certain error.
At present, for each eyeglass after guaranteeing to assemble and lens barrel have good with one heart with the footpath degree, normally eyeglass directly is placed in the lens barrel, and each eyeglass and lens barrel all is connected on the special-purpose assembling lathe, aim at by deciding China National Instruments Import ﹠ Export Corporation, guarantee in fixed each eyeglass with one heart with footpath degree requirement.But, needing in the said method to adopt special-purpose assembling lathe, cost is higher, and method also not easy to operate, and this can't be proofreaied and correct the error of relative spacing between the eyeglass.After lens module group assembling is finished, even defective products in test process, occurs, also can't carry out the heavy industry improvement to it, it can only be scrapped.
Summary of the invention
In view of this, be necessary to provide a kind of simple in structure and can also be to the camera lens module of finely tuning with footpath degree and relative spacing with one heart of lens set after assembling is finished, and the assemble method of this camera lens module.
A kind of camera lens module, comprise: the first lens barrel, it has a through hole, this through-hole wall is provided with a circular horizontal projection along its circumferencial direction, this circular horizontal projection is divided into the first through hole and the second through hole with this through hole, this circular horizontal projection has one first loading end, this first loading end formed by the some identical zone of continuous distribution along the circumferential direction and each adjacent area between seamlessly transit, this each zone is by the convex flat face that is higher than this first loading end, the plane that is lower than the concave plane of this first loading end and overlaps with this first loading end forms, and seamlessly transits between this each face; At least one first eyeglass, it is fixed in this second through hole; The second lens barrel, it has body, the first end face and the second end face, one third through-hole runs through this body, the first end face reaches the second end face towards the thing side, this second lens barrel is embedded in the first through hole of this first lens barrel, be provided with at least one groove or fin in the second end face of this second lens barrel, this groove or fin are used for cooperating a tool that this second lens barrel is rotated with respect to this first lens barrel; Second eyeglass, the non-optical division of this second eyeglass has a mating surface, this second eyeglass is fixed in the third through-hole of this second lens barrel, this mating surface is relative with the circular horizontal projection in this first lens barrel, in the mating surface of this second eyeglass, be provided with some boss, its position respectively with this some by convex flat face, concave plane and plane form the zone in same level corresponding.
And the assemble method of this camera lens module, its step comprises: at least one second lens set enters in the interior third through-hole of this second lens barrel with this, and some glue is fixed; At least one first lens set enters in the second through hole of this first lens barrel with this, and some glue is fixed; This second lens barrel group that assembles is entered in this first lens barrel first through hole, and this boss is born against on this circular horizontal projection; This camera lens module is tested, as tested undesirablely, then utilize a tool to rotate the second lens barrel by this groove or fin and finely tune, until the test result of camera lens module meets the requirements.
Compared with prior art, camera lens module provided by the present invention is individually fixed in the first eyeglass and the second eyeglass in this first lens barrel and the second lens barrel, this second lens barrel is embedded in this first lens barrel, in one end face of this second lens barrel some grooves are set, making this second lens barrel drive this second eyeglass with a tool by these some grooves rotates with respect to this first lens barrel, simultaneously, in on this second eyeglass and the mating surface that this first lens barrel matches some boss are set, the loading end that is used for carrying this second eyeglass on this first lens barrel is arranged to the convex-concave plane matches with this boss, and this boss can slide in this convex-concave plane.Both can also can finely tune the relative spacing between eyeglass simultaneously finely tuning with the footpath degree with one heart of lens set in the camera lens module by this structure, thereby in the lens module group assembling process or after assembling finishes, can finely tune to increase to underproof camera lens module the yield of product.
