Description
本發明係一種整合對焦機構的分體式鏡頭及其組裝方法和攝像模組，尤其涉及整合對焦機構的鏡頭及其組裝方法和攝像模組。 The invention relates to a split lens integrating a focusing mechanism, an assembly method thereof, and a camera module, in particular to a lens integrating a focusing mechanism, an assembly method thereof, and a camera module.
隨著攝像頭模組市場競爭的日益激烈，攝像模組製造成本的下降、生產效率的提高及成像質量的提高是已成為攝像模組製造廠家不斷追逐的目標。 With the increasingly fierce competition in the camera module market, the decline in camera module manufacturing costs, the improvement of production efficiency and the improvement of imaging quality have become the goals that camera module manufacturers continue to pursue.
通常情況下，可調焦攝像模組由鏡頭、對焦機構、感光晶片等重要部件組成，可調焦攝像模組的製造通常也是這些部件之間的組裝，其中鏡頭與對焦機構的製造本身也是各個零部件的組裝，組裝完成後再將鏡頭成品與對焦機構進行組裝，進而完成攝像模組的組裝。這種方法有以下幾個問題：第一，組裝工藝比較重複繁瑣，導致攝像模組的生產效率較低；第二，鏡頭與對焦機構之間存在組裝公差，再加上鏡頭、對焦機構本身的組裝公差，使公差鏈過長，影響模組品質；第三，這種方式生產的模組在長寬方向上的尺寸較大，不利於攝像模組向輕薄化的方向發展；第四，鏡頭和對焦機構在裝配過程中極易進入灰塵，出現汙點不良現象，這是由於鏡頭和對焦機構之間的連接並沒有那麼緊密，有時候會有一些小的縫隙，使得灰塵會進入鏡頭和對焦機構之間，很難除去，而如果模組內部的灰塵長時間得不到除去，則會使鏡頭、對焦機構 以及整個模組受到污染，影響成像質量及使用壽命，最終會影響裝帶有攝像模組的整個產品的質量。 Normally, the adjustable focus camera module is composed of important components such as the lens, focusing mechanism, and photosensitive chip. The manufacture of the adjustable focus camera module is usually the assembly between these components. The manufacturing of the lens and the focusing mechanism itself After the assembly of the parts, the finished lens and the focusing mechanism are assembled to complete the assembly of the camera module. This method has the following problems: First, the assembly process is more repetitive and cumbersome, resulting in lower production efficiency of the camera module; second, there are assembly tolerances between the lens and the focusing mechanism, plus the lens and focusing mechanism itself Assembly tolerances make the tolerance chain too long and affect the quality of the module; third, the module produced in this way has a larger size in the length and width directions, which is not conducive to the development of the camera module in the direction of light and thin; fourth, the lens And the focusing mechanism is easy to get into dust during the assembly process, and the phenomenon of poor stains occurs. This is because the connection between the lens and the focusing mechanism is not so tight, sometimes there are some small gaps, so that dust will enter the lens and focusing mechanism It is difficult to remove the dust, and if the dust inside the module is not removed for a long time, it will make the lens and focusing mechanism And the entire module is contaminated, which affects the image quality and service life, and ultimately affects the quality of the entire product with the camera module.
此外，對於分體式鏡頭模組，在將各個鏡筒組裝形成攝像模組的過程中，各個鏡筒之間的組裝也存在組裝公差，傳統的分體式鏡頭的各個鏡頭固定到一起形成分體式鏡頭模組，而且已經生產完成的分體式鏡頭模組無法再進行校正，這些公差會導致鏡頭的光學品質不穩定，從而影響整個攝像模組的生產效率及成像質量。所以，在攝像模組的鏡頭模組的製造過程中，如何保分體式鏡頭在被製造後的成像品質也成為亟待解決的問題。 In addition, for split lens modules, in the process of assembling each lens barrel to form a camera module, there are assembly tolerances between the assembly of each lens barrel. The lenses of the traditional split lens are fixed together to form a split lens. Modules, and the split lens modules that have been produced cannot be corrected. These tolerances will cause the optical quality of the lens to be unstable, thereby affecting the production efficiency and imaging quality of the entire camera module. Therefore, in the manufacturing process of the lens module of the camera module, how to maintain the imaging quality of the split-body lens after being manufactured has also become an urgent problem to be solved.
綜上，在攝像模組的製造過程中，如何有效的解決上述問題是提高攝像模組製造良率與品質的關鍵。 In summary, in the manufacturing process of the camera module, how to effectively solve the above-mentioned problems is the key to improving the manufacturing yield and quality of the camera module.
