具有自動對焦功能之攝影模組Photographic module with auto focus function

本發明係關於一種攝影模組，特別地，本發明關於一種攝影模組，其安裝於終端中且具有對物體自動對焦之功能。The present invention relates to a photographic module. In particular, the present invention relates to a photographic module that is mounted in a terminal and has a function of automatically focusing an object.

安裝於小型終端(例如數位相機或者可攜式電話)中的攝影模組採用電荷耦合器件(CCD)型或者互補金屬氧化物半導體(CMOS)型之影像感測器。攝影模組將光訊號轉換成電訊號以形成一影像。A photographic module mounted in a small terminal (such as a digital camera or a portable telephone) uses a charge coupled device (CCD) type or a complementary metal oxide semiconductor (CMOS) type image sensor. The photography module converts the optical signal into an electrical signal to form an image.

攝影模組具有對物體進行自動對焦之功能。為此，具有自動對焦功能之攝影模組包含有相對於影像感測器改變透鏡位置的自動對焦調節裝置。The photography module has the function of autofocusing objects. To this end, the photographic module with autofocus function includes an autofocus adjustment device that changes the position of the lens relative to the image sensor.

傳統的自動對焦調節裝置使得透鏡沿光軸方向直線運動，以使得一馬達之旋轉運動透過一轉換機構(例如齒輪)轉換為直線運動。然而，由於自動對焦調節裝置使用齒輪，所以難以精確地調節聚焦。進一步而言，由於馬達及齒輪佔據空間，所以對終端尺寸之減小產生限制。The conventional autofocus adjusting device linearly moves the lens in the optical axis direction so that the rotational motion of a motor is converted into a linear motion through a switching mechanism (for example, a gear). However, since the autofocus adjusting device uses a gear, it is difficult to precisely adjust the focus. Further, since the motor and the gear occupy a space, there is a limit to the reduction in the size of the terminal.

為了解決上述問題，提出音圈馬達(Voice Coil Motor,VCM)型的自動對焦調節裝置。在音圈馬達(VCM)型的自動對焦調節裝置中，產生磁力的永磁體與作用有電流的線圈相面對，並且透鏡的位置通過垂直於磁場及電流產生的羅倫茲力而改變。In order to solve the above problem, an automatic focus adjustment device of a voice coil motor (VCM) type has been proposed. In the voice coil motor (VCM) type of the autofocus adjusting device, the permanent magnet that generates the magnetic force faces the coil to which the current is applied, and the position of the lens is changed by the Lorentz force generated perpendicular to the magnetic field and the current.

在音圈馬達(VCM)型的自動對焦調節裝置中，線圈連接至一印刷電路板(PCB)上，以使得電流能夠供給至線圈。為此，線圈的配線端子固化至印刷電路板(PCB)的連接終端。In a voice coil motor (VCM) type of autofocus adjustment device, a coil is connected to a printed circuit board (PCB) to enable current to be supplied to the coil. To this end, the wiring terminals of the coil are cured to the connection terminals of the printed circuit board (PCB).

然而，在音圈馬達(VCM)型的自動對焦調節裝置中，存在透鏡之對焦應透過調零相對於印刷電路板(PCB)精確地調節之情況。當具有透鏡的鏡頭部份相對于印刷電路板(PCB)旋轉時，線圈的配線端子根據鏡頭部份的旋轉角度可不連接至印刷電路板(PCB)之連接終端上。為此，配線端子可不固化至連接終端。However, in the voice coil motor (VCM) type of autofocus adjustment device, there is a case where the focus of the lens should be accurately adjusted with respect to the printed circuit board (PCB) by zero adjustment. When the lens portion having the lens is rotated relative to the printed circuit board (PCB), the wiring terminal of the coil may not be connected to the connection terminal of the printed circuit board (PCB) according to the rotation angle of the lens portion. For this reason, the wiring terminal may not be cured to the connection terminal.

透過增加配線端子的長度可以解決此問題。然而，此種情況下，配線端子在固化至連接終端之後可不需要保留長度，這樣導致出現如何處理配線端子的問題。This problem can be solved by increasing the length of the wiring terminals. However, in this case, the wiring terminal does not need to retain the length after curing to the connection terminal, which causes a problem of how to handle the wiring terminal.

因此，鑒於上述問題，本發明之目的在於提供一種具有自動對焦功能之攝影模組，其中當為了精確的對焦調節而使鏡頭部份相對于印刷電路板(PCB)旋轉時，線圈部份之配線端子能夠容易地連接至印刷電路板(PCB)的連接終端上，而不管線圈部份的配線端子之位置如何。Therefore, in view of the above problems, an object of the present invention is to provide a photographing module having an autofocus function in which a coil portion is wired when a lens portion is rotated relative to a printed circuit board (PCB) for precise focus adjustment.

請參閱「第1圖」至「第5圖」，本發明之實施例的攝影模組1包含有一鏡頭部份11、一線圈部份12、一磁體部份13、一彈簧14、一基座16以及一端子延伸部份17。Referring to FIG. 1 to FIG. 5, the camera module 1 of the embodiment of the present invention includes a lens portion 11, a coil portion 12, a magnet portion 13, a spring 14, and a base. 16 and a terminal extension portion 17.

鏡頭部份11包含有至少一個透鏡112。透鏡112功能上用於形成一物體之一光學影像。鏡頭部份11包含有容納透鏡112的鏡筒111。鏡筒111之上部敞開，以使得光線能夠進入透鏡112。鏡筒111之下部敞開，以使得穿過透鏡112之光線能夠傳輸至安裝於透鏡112之下的一影像感測器183。The lens portion 11 includes at least one lens 112. Lens 112 is functionally used to form an optical image of an object. The lens portion 11 includes a lens barrel 111 that houses the lens 112. The upper portion of the lens barrel 111 is open to allow light to enter the lens 112. The lower portion of the lens barrel 111 is open so that light passing through the lens 112 can be transmitted to an image sensor 183 mounted under the lens 112.

線圈部份12圍繞鏡頭部份11，並且例如透過一黏合劑固定至鏡頭部份11。線圈部份12位於透過磁體部份13產生的磁場之中。當電流自印刷電路板(PCB)181供給時，磁體部份13通過洛倫茲力沿著光軸方向作直線運動。固定至線圈部份12的鏡頭部份11沿著光軸方向作直線運動。因此，透鏡112之位置相對於影像感測器183改變，使得能夠自動調節對焦。The coil portion 12 surrounds the lens portion 11 and is fixed to the lens portion 11 by, for example, an adhesive. The coil portion 12 is located in a magnetic field generated by the magnet portion 13. When current is supplied from the printed circuit board (PCB) 181, the magnet portion 13 linearly moves in the optical axis direction by the Lorentz force. The lens portion 11 fixed to the coil portion 12 linearly moves in the optical axis direction. Therefore, the position of the lens 112 is changed with respect to the image sensor 183, so that the focus can be automatically adjusted.

磁體部份13設置為使得磁場能夠作用於線圈部份12。磁體部份13透過基座16支撐。基座16具有一環形，並且外螺紋161形 成於外周表面上。The magnet portion 13 is disposed such that a magnetic field can act on the coil portion 12. The magnet portion 13 is supported by the base 16. The base 16 has an annular shape and an external thread 161 shape On the outer peripheral surface.

彈簧14位於鏡頭部份11與基座16之間，以彈性地抵靠基座16支撐鏡頭部份11。也就是說，當鏡頭部份11透過施加至鏡頭部份11上的力沿著光軸移動時，彈簧14彈性地變形。當作用至鏡頭部份11上的力去除時，透過彈簧14產生恢復力，並且因此鏡頭部份11通過恢復力返回初始位置。彈簧14可按照片簧的形式構造。The spring 14 is located between the lens portion 11 and the base 16 to elastically support the lens portion 11 against the base 16. That is, when the lens portion 11 is moved along the optical axis by the force applied to the lens portion 11, the spring 14 is elastically deformed. When the force applied to the lens portion 11 is removed, the restoring force is generated by the spring 14, and thus the lens portion 11 returns to the initial position by the restoring force. The spring 14 can be constructed in the form of a photo spring.

一上部彈簧15可更位於鏡頭部份11之上。一頭部19可位於上部彈簧15之上。上部彈簧15位於頭部19與鏡頭部份11之間，以抵靠頭部19彈性地支撐鏡頭部份11。An upper spring 15 can be located further above the lens portion 11. A head 19 can be located above the upper spring 15. The upper spring 15 is located between the head portion 19 and the lens portion 11 to elastically support the lens portion 11 against the head portion 19.

基座16螺紋結合至保持件18，保持件18例如透過黏合劑固定至印刷電路板(PCB)。也就是說，基座16之外螺紋161可螺紋結合至保持件18之內螺紋。當基座16在螺紋結合至保持件18上的狀態下正向或者反向旋轉時，鏡頭部份11向上或者向下運動。通過此過程，透鏡112的對焦能夠精確調節。影像感測器183位於印刷電路板(PCB)181之上，並且一通孔形成於保持件18之中心，以暴露影像感測器183之頂部。印刷電路板(PCB)181將用於透鏡112的對焦調節之控制電流作用至線圈部份12。影像感測器183將透過透鏡112形成之一光學影像轉換為一電訊號。影像感測器183可為一電荷耦合器件(CCD)型或者一互補金屬氧化物半導體(CMOS)型。The base 16 is threadedly coupled to a retainer 18 that is secured to a printed circuit board (PCB), such as by an adhesive. That is, the outer thread 161 of the base 16 can be threadedly coupled to the internal thread of the holder 18. When the base 16 is rotated in the forward or reverse direction in a state where the screw 16 is screwed to the holder 18, the lens portion 11 moves upward or downward. Through this process, the focus of the lens 112 can be precisely adjusted. The image sensor 183 is located above the printed circuit board (PCB) 181, and a through hole is formed in the center of the holder 18 to expose the top of the image sensor 183. A printed circuit board (PCB) 181 applies a control current for focus adjustment of the lens 112 to the coil portion 12. The image sensor 183 converts an optical image formed through the lens 112 into an electrical signal. The image sensor 183 can be a charge coupled device (CCD) type or a complementary metal oxide semiconductor (CMOS) type.

由於基座16與鏡頭部份11一起構成組件，並且與保持件18螺紋結合，所以能夠執行精確的對焦調節。鏡頭部份11之狀態在 精確對焦調節之後不改變，所以這種精確的對焦調節能容易地執行。進一步而言，由於在精確的對焦調節過程中沒有力作用至彈簧14及上部彈簧15，所以能夠降低彈簧14及上部彈簧15之損壞。Since the susceptor 16 constitutes an assembly together with the lens portion 11, and is threadedly coupled to the holder 18, accurate focus adjustment can be performed. The state of the lens portion 11 is This does not change after the precise focus adjustment, so this precise focus adjustment can be easily performed. Further, since no force acts on the spring 14 and the upper spring 15 during precise focus adjustment, damage of the spring 14 and the upper spring 15 can be reduced.

與配線端子7及8分別相連接的第一終端171及第二終端172形成於端子延伸部份17之中。端子延伸部份17形成為使得第一終端171及第二終端172即使在基座16相對於保持件18旋轉時，也能夠與印刷電路板(PCB)181之連接終端182相接觸。連接終端182包含有多個觸點，這些觸點分別與第一終端171及第二終端172相連接，並且形成於面對第一終端171及第二終端172之表面上。The first terminal 171 and the second terminal 172 which are connected to the wiring terminals 7 and 8, respectively, are formed in the terminal extension portion 17. The terminal extension portion 17 is formed such that the first terminal 171 and the second terminal 172 can be in contact with the connection terminal 182 of the printed circuit board (PCB) 181 even when the susceptor 16 is rotated relative to the holder 18. The connection terminal 182 includes a plurality of contacts that are respectively connected to the first terminal 171 and the second terminal 172 and formed on surfaces facing the first terminal 171 and the second terminal 172.

也就是說，對焦透過使得基座16相對於保持件18正向地或者反向地旋轉精確地調節，並且在這種狀態下，連接至配線端子7及8的第一終端171及第二終端172連接且固定至印刷電路板181之連接終端182。也就是說，在透過將基座16相對於保持件18正向或者反向旋轉來執行精確對焦調節的過程中，不管線圈部份12之配線端子7及8的位置如何，連接至配線端子7及8的第一終端171及第二終端172總是與印刷電路板181之連接終端182相接觸。因此，由於當鏡頭對焦時，第一終端171及第二終端172連接並固定至印刷電路板181之連接終端182，所以組裝過程得以簡化。That is, the focus transmission precisely adjusts the rotation of the susceptor 16 with respect to the holder 18 in the forward or reverse direction, and in this state, the first terminal 171 and the second terminal connected to the wiring terminals 7 and 8 172 is connected and fixed to the connection terminal 182 of the printed circuit board 181. That is, in the process of performing precise focus adjustment by rotating the susceptor 16 in the forward or reverse direction with respect to the holder 18, regardless of the position of the wiring terminals 7 and 8 of the coil portion 12, it is connected to the wiring terminal 7 The first terminal 171 and the second terminal 172 of the terminal 8 are always in contact with the connection terminal 182 of the printed circuit board 181. Therefore, since the first terminal 171 and the second terminal 172 are connected and fixed to the connection terminal 182 of the printed circuit board 181 when the lens is in focus, the assembly process is simplified.

第一終端171及第二終端172可形成於端子延伸部份17的一個表面上。端子延伸部份17可具有圍繞磁體部份13之外周表面的結構，使得第一終端171及第二終端172能夠暴露於外。The first terminal 171 and the second terminal 172 may be formed on one surface of the terminal extension portion 17. The terminal extension portion 17 may have a structure surrounding the outer peripheral surface of the magnet portion 13, so that the first terminal 171 and the second terminal 172 can be exposed to the outside.

端子延伸部份17可包含有一圓環構件173及一帶構件174。第一終端171及第二終端172可遍及圓環構件173及帶構件174上形成。圓環構件173位於彈簧14之上並且與基座16相結合。分別與第一終端171及第二終端172連接的觸點形成於圓環構件173之中，並且這些觸點分別與線圈部份12之配線端子7及8相連接。舉例而言，如「第3圖」所示，第一終端171可沿著圓環構件173之自觸點開始至帶構件174為止的一半延伸，此觸點形成於圓環構件中以與配線端子7相連接，第二終端172可沿著圓環構件173之自觸點開始至帶構件174為止的另一半延伸，此觸點形成於圓環構件中以與配線端子8相連接。The terminal extension portion 17 can include a ring member 173 and a strap member 174. The first terminal 171 and the second terminal 172 can be formed over the ring member 173 and the belt member 174. The ring member 173 is located above the spring 14 and is coupled to the base 16. Contacts respectively connected to the first terminal 171 and the second terminal 172 are formed in the ring member 173, and these contacts are respectively connected to the wiring terminals 7 and 8 of the coil portion 12. For example, as shown in FIG. 3, the first terminal 171 may extend along a half of the ring member 173 from the contact to the tape member 174, and the contact is formed in the ring member to be wired. The terminals 7 are connected, and the second terminal 172 may extend along the other half of the ring member 173 from the contact to the belt member 174, and the contact is formed in the ring member to be connected to the wiring terminal 8.

帶構件174與圓環構件173整體地形成，並且自圓環構件173延伸至基座16的外部。帶構件174可以由柔軟的可撓性材料製成。因此，帶構件174能夠彎曲以圍繞磁體部份13的外周表面。帶構件174可包含有形成於一表面上的黏附部份，該表面與形成有第一終端171及第二終端172的表面相面對。黏附部份可由具有黏合劑及一雙面膠帶的材料製成。帶構件174通過黏附部份固定至磁體部份13。The belt member 174 is integrally formed with the ring member 173 and extends from the ring member 173 to the outside of the base 16. The strap member 174 can be made of a soft, flexible material. Therefore, the belt member 174 can be bent to surround the outer peripheral surface of the magnet portion 13. The strap member 174 may include an adhesive portion formed on a surface that faces the surface on which the first terminal end 171 and the second terminal end 172 are formed. The adhesive portion can be made of a material having a binder and a double-sided tape. The belt member 174 is fixed to the magnet portion 13 by an adhesive portion.

當帶構件174圍繞磁體部份13之外周表面使得帶構件174的一個表面能夠透過黏附部份黏附至磁體部份13的外周表面上時，帶構件174之第一終端171及第二終端172暴露於外。因此，攝影模組之組裝過程簡單，從而使得生產率提高。When the belt member 174 surrounds the outer peripheral surface of the magnet portion 13 such that one surface of the belt member 174 can be adhered to the outer peripheral surface of the magnet portion 13 through the adhesive portion, the first terminal 171 and the second terminal 172 of the belt member 174 are exposed. Outside. Therefore, the assembly process of the photographic module is simple, resulting in an increase in productivity.

在帶構件174之第一終端171及第二終端172沿著磁體部份13的外周表面設置的狀態下，印刷電路板181之連接終端182對 應於帶構件174之外表面延伸，以接觸第一終端171及第二終端172。即使印刷電路板181的連接終端182相對於磁體部份13之位置根據基座16相對於保持件18的旋轉位置而改變，連接終端182總能夠與第一終端171及第二終端172相接觸。因此，當基座16相對於保持件18旋轉時，線圈部份12之配線端子7及8能夠與印刷電路板181之連接終端182電連接，而不管配線端子7及8之位置如何。In a state where the first terminal 171 and the second terminal 172 of the tape member 174 are disposed along the outer peripheral surface of the magnet portion 13, the connection terminal 182 of the printed circuit board 181 is paired The outer surface of the strap member 174 should extend to contact the first terminal 171 and the second terminal 172. Even if the position of the connection terminal 182 of the printed circuit board 181 with respect to the magnet portion 13 is changed according to the rotational position of the susceptor 16 with respect to the holder 18, the connection terminal 182 can always be in contact with the first terminal 171 and the second terminal 172. Therefore, when the susceptor 16 is rotated relative to the holder 18, the wiring terminals 7 and 8 of the coil portion 12 can be electrically connected to the connection terminal 182 of the printed circuit board 181 regardless of the positions of the wiring terminals 7 and 8.

磁體部份13可包含有一永磁體131、一內磁軛132以及一外磁軛133。永磁體131可具有圍繞鏡頭部份11的圓環形狀。內磁軛132透過例如黏結劑固定至永磁體131的兩個磁極中的一個並且設置於線圈部份12之內。外磁軛133透過例如黏結劑固定至永磁體131的兩個磁極中之另一個並且設置於線圈部份12之外部。The magnet portion 13 may include a permanent magnet 131, an inner yoke 132, and an outer yoke 133. The permanent magnet 131 may have a ring shape surrounding the lens portion 11. The inner yoke 132 is fixed to one of the two magnetic poles of the permanent magnet 131 by, for example, an adhesive and is disposed inside the coil portion 12. The outer yoke 133 is fixed to the other of the two magnetic poles of the permanent magnet 131 by, for example, a bonding agent and disposed outside the coil portion 12.

舉例而言，永磁體131可構造為使得其上端和下端具有彼此不同的磁極。內磁軛132固定至永磁體131之下端，以與永磁體131的下端具有相同的磁極。內磁軛132可形成為面對線圈部份12的內部向下彎曲。也就是說，內磁軛132可包含有支撐永磁體131的水平部份132a及自水平部份132a向下延伸面對線圈部份12的豎直部份132b。For example, the permanent magnet 131 may be configured such that its upper end and lower end have magnetic poles different from each other. The inner yoke 132 is fixed to the lower end of the permanent magnet 131 to have the same magnetic pole as the lower end of the permanent magnet 131. The inner yoke 132 may be formed to face downward toward the inside of the coil portion 12. That is, the inner yoke 132 may include a horizontal portion 132a supporting the permanent magnet 131 and a vertical portion 132b extending downward from the horizontal portion 132a facing the coil portion 12.

外磁軛133可彎曲以圍繞永磁體131的外部並向下延伸，並且外磁軛133之下端可例如透過黏結劑固定至基座16。也就是說，外磁軛133可包含有與內磁軛132一起支撐永磁體131的水平部份133a及自水平部份133a向下延伸面對線圈部份12的豎直部份133b。因此，由於外磁軛133覆蓋了攝影模組1的外遮蓋物， 並且防止外部雜質入侵，所以，外磁軛133具有覆蓋攝影模組1的外遮蓋物並保護攝影模組1之外罩的功能。因此，可減小攝影模組的尺寸。The outer yoke 133 may be bent to surround the outer portion of the permanent magnet 131 and extend downward, and the lower end of the outer yoke 133 may be fixed to the susceptor 16 by, for example, an adhesive. That is, the outer yoke 133 may include a horizontal portion 133a that supports the permanent magnet 131 together with the inner yoke 132 and a vertical portion 133b that extends downward from the horizontal portion 133a to face the coil portion 12. Therefore, since the outer yoke 133 covers the outer cover of the photographic module 1, Further, since the external foreign matter is prevented from intruding, the outer yoke 133 has a function of covering the outer cover of the photographing module 1 and protecting the outer cover of the photographing module 1. Therefore, the size of the photographic module can be reduced.

向下延伸的內磁軛132之豎直部份132b與向下延伸的外磁軛133之豎直部份133b相對於位於上述兩者之間的線圈部份12彼此面對地平行設置。因此，內磁軛132和外磁軛133感應磁力線的流動以水平地形成於其間並且穿過線圈部份12。The vertical portion 132b of the downwardly extending inner yoke 132 and the vertical portion 133b of the downwardly extending outer yoke 133 are disposed in parallel with each other with respect to the coil portion 12 located therebetween. Therefore, the inner yoke 132 and the outer yoke 133 sense the flow of magnetic lines of force to be horizontally formed therebetween and pass through the coil portion 12.

在上述線圈部份12的結構中，端子延伸部份17的帶構件174可固定至外磁軛133之外周表面上。當外磁軛133之下端固定至基座16之內部時，外磁軛133之外周表面自基座16的外周表面凹入。端子延伸部份17固定至凹入部份，因此，攝影模組1之結構能夠進一步緊湊。In the structure of the coil portion 12 described above, the belt member 174 of the terminal extending portion 17 can be fixed to the outer peripheral surface of the outer yoke 133. When the lower end of the outer yoke 133 is fixed to the inside of the susceptor 16, the outer peripheral surface of the outer yoke 133 is recessed from the outer peripheral surface of the susceptor 16. The terminal extension portion 17 is fixed to the recessed portion, so that the structure of the photographic module 1 can be further compact.

在外磁軛133之上，可組裝頭部19以侷部覆蓋外磁軛133之外周表面，在外磁軛133之下，可組裝基座16以侷部覆蓋外磁軛133之外周表面。頭部19之下端與基座16之上端彼此分隔開，以在二者之間形成凹入部份。端子延伸部份17位於凹入部份之上，並且固定至外磁軛133之外周表面。因此，攝影模組1之結構簡單，並攝影模組1的尺寸減小。Above the outer yoke 133, the head portion 19 can be assembled to partially cover the outer peripheral surface of the outer yoke 133, and under the outer yoke 133, the susceptor 16 can be assembled to partially cover the outer peripheral surface of the outer yoke 133. The lower end of the head 19 is spaced apart from the upper end of the base 16 to form a concave portion therebetween. The terminal extending portion 17 is located above the concave portion and is fixed to the outer peripheral surface of the outer yoke 133. Therefore, the structure of the photographic module 1 is simple, and the size of the photographic module 1 is reduced.
