Under the market demand, optical imaging modules have faced the dual requirements of higher quality and miniaturization. While using a handheld device for image capture, zooming and focusing of the lens are essential for each optical imaging module. The conventional design drives the zoom lens barrel and the focus lens group to drive and unfold the motion by different motors. This method has its own driving motor and mechanism for both the zoom lens barrel and the focus lens group. When the motor rotates too fast or too slow, the zoom lens barrel and the focus lens group collide with each other, and damage to the components occurs. SUMMARY OF THE INVENTION Therefore, one aspect of the present disclosure is to provide a lens linkage anti-collision device to overcome the above-mentioned zoom lens barrel and the focus lens group in the process of linkage, because any of the motor speeds are too fast or too slow And the problem of colliding with each other'. According to an embodiment of the present invention, a lens linkage anti-collision device is provided, which comprises an optical module, a driving module and a linkage controller. The 201250330 optical module consists of a 1 tube and a listening unit. For f, the mirror is located in the zoom barrel. The driving module is configured to drive the optical module to perform displacement, wherein the driving module comprises a first motor and a second motor. The first motor is used to drive the zoom lens barrel for axial telescopic displacement. The second motor is used to adjust the position of the pair in the zoom lens barrel. The linkage controller is configured to control the first motor and the second motor to interlock with each other, and control the rotation speed of the first motor to be proportional to the first rotation speed, so that the zoom lens barrel and the focus lens group do not collide during the interlocking process. mutual
更進一步的說，在本技術態樣其他實施方式中，第一 馬達之轉速與第二馬達之轉速可成直線正比關係。再者T 此直線正比關係的斜率可為0.793。另外，筮 » 1弗一馬達驅動縮 放鏡筒之步數範圍可由-876步至110步。第二馬達驅動對 焦鏡組之步數範圍可由-727步至512步。 依據本技術態樣另-實施方式，提出一種鏡頭連動防 撞裝置，其包含一縮放鏡筒、一對焦鏡組、一第一馬達、 一第二馬達及一連動控制器，對焦鏡組位於縮放鏡筒内， 第一馬達與縮放鏡筒連接，並驅動縮放鏡筒進行軸向伸縮 位移，第一馬達與對焦鏡組連接，並調整該對焦鏡組於縮 放鏡筒中的位置。其中，連動控制器用以控制第一馬達及 第二馬達彼此連動，並控制第一馬達之轉速正比於第二馬 達之轉速，使縮放鏡筒及對焦鏡組於連動過程中不會相互 碰撞。 更進一步的說，在本技術態樣其他實施方式中，第一 馬達之轉速與第二馬叙轉速可成直線正比_。此外， 前述直線正比關係的斜率可為0.793。 201250330 本揭示内容之另一技術態樣在於提供一種鏡頭連動防 撞方法，以克服上述縮放鏡筒及對焦鏡組在連動的過程 中’因其中任一馬達轉速過快或過慢，而發生相互碰撞的 問題。 依據本技術態樣一實施方式，提出一種鏡頭連動防撞 方法，至少包含下列步驟：選定一第一馬達以驅動—縮放 . 鏡筒進行軸向伸縮位移。選定一第二馬達以調整—對焦鏡 組於縮放鏡筒中的位置。計算縮放鏡筒追撞對焦鏡組日^二 第一馬達及第·一馬達兩者轉速的一第一斜率值。計算對焦 鏡組追撞縮放鏡筒時，第一馬達及第二馬達兩者轉速的二 第二斜率值。利用一連動控制器來控制第一馬達及第二馬 達，使兩者轉速的斜率值位於第一斜率值及第二斜率值之 間。 更進一步的說，在本技術態樣其他實施方式中，可再 包含下述步驟：控制第一馬達驅動縮放鏡筒之步數範圍為 -876步至11〇步，且控制第二馬達驅動對焦鏡組之步數範 圍為-727步至512步，進而使第一馬達及第二馬達兩者轉 速的斜率為0.793。 藉此，上述諸實施方式利用連動控制器以斜率連動的 方式，確保縮放鏡同及對焦鏡組在連動的過程中伴持一定 間隙，而不會有兩者碰撞的情形發生。 【實施方式】 第1圖繪示本揭示内容一實施方式之鏡頭連動防撞裝 置的功能方塊圖。如第1圖所示，鏡頭連動防撞裝置1〇〇 201250330 包含一光學模組110、一驅動模組120及一連動控制器 130。連動控制器130控制藉由斜率連動的方式，控制驅動 模組120,以避免光學模組110内部構件碰撞損壞的情形。 光學模組110包含一縮放鏡筒111及一對焦鏡組112。 對焦鏡組112位於縮放鏡筒111内，使用者可改變對焦鏡 組112於縮放鏡筒111内的位置，來改變焦距並達到對一 物體聚焦的功效。 驅動模組120用以驅動光學模組110進行位移，其中， 驅動模組120包含一第一馬達121及一第二馬達122。第 一馬達121用以驅動縮放鏡筒111進行軸向伸縮位移。第 二馬達122用以調整對焦鏡組112於縮放鏡筒111中的位 置。 連動控制器130用以控制第一馬達121及第二馬達122 彼此連動，並控制第一馬達121之轉速正比於第二馬達122 之轉速，在本實施方式中，第一馬達121及第二馬達122 的轉速成直線正比關係。如此一來，縮放鏡筒111及對焦 鏡組112於連動過程中，由於連動控制器130會隨著時間 對第一馬達121及第二馬達122的轉速進行調整，因此不 會有縮放鏡筒111及對焦鏡組112相互碰撞的情形發生。 至於連動控制器130如何對第一馬達121及第二馬達 122的轉速進行調整，這個部份的細部内容將於後續鏡頭 連動防撞方法300中作說明。 第2圖繪示本揭示内容一實施方式之鏡頭連動防撞裝 置的功能方塊圖。如第2圖所示，鏡頭連動防撞裝置200 包含一縮放鏡筒210、一對焦鏡組220、一第一馬達230、 201250330 一第二馬達240及一連動控制器250。連動控制器250控 制藉由斜率連動的方式，控制第一馬達230及第二馬達 240’進而避免縮放鏡筒210與對焦鏡組220發生碰撞損壞 的情形。 對焦鏡組220位於縮放鏡筒210内，第一馬達230與 縮放鏡筒210連接，並驅動縮放鏡筒21 〇進行軸向伸縮位 移’第二馬達240與對焦鏡組220連接，並調整該對焦鏡 組220於縮放鏡筒210中的位置。 連動控制器250用以控制第一馬達230及第二馬達240 彼此連動’並控制第一馬達230之轉速正比於第二馬達240 之轉速’在本實施方式中’第一馬達230及第二馬達240 的轉速成直線正比關係。如此一來，縮放鏡筒210及對焦 鏡組220於連動過程中’由於連動控制器250會隨著時間 對第一馬達230及第二馬達240的轉速進行調整，因此不 會有縮放鏡筒210及對焦鏡組220相互碰撞的情形發生。 至於連動控制器250如何對第一馬達230及第二馬達 240的轉速進行調整，這個部份的細部内容同樣將於後續 鏡頭連動防撞方法300中作說明。 第3圖繪示本揭示内容另一實施方式之鏡頭連動防撞 方法的步驟流程圖。如第3圖所示，本實施方式之鏡頭連 動防撞方法300，至少包含下列步驟：首先，如步驟31〇 所示’選定一第一馬達以驅動一縮放鏡筒進行軸向伸縮位 移。再者，如步驟320所示，選定一第二馬達以調整一對 焦鏡組於縮放鏡筒中的位置。然後，如步驟330所示，計 算縮放鏡筒追撞對焦鏡組時’第一馬達及第二馬達兩者轉 201250330 速的一第一斜率值。接下來，如步驟340所示，計算對焦 鏡組追撞縮放鏡筒時，第一馬達及第二馬達兩者轉速的一 第二斜率值。最後，如步驟350所示，利用一連動控制器 來控制第一馬達及第二馬達，使兩者轉速的斜率值位於第 一斜率值及第二斜率值之間。 簡而言之，連動控制器會隨著時間分別監控第一馬達 及第二馬達，隨時計算兩者轉速的斜率值，並依據算出的 斜率值落點來分別控制第一馬達及第二馬達的轉速。具體 來說，可將第一馬達及第二馬達驅動縮放鏡筒及對焦鏡組 由收納至展開的過程，分成以下三個情況：第一，當第一 馬達及第二馬達兩者轉速的斜率值大於第一斜率值時，代 表驅動縮放鏡筒的第一馬達轉速過快，此時，連動控制器 會控制第二馬達提升至最高速轉動，以避免縮放鏡筒及對 焦鏡組相互碰撞；第二，當第一馬達及第二馬達兩者轉速 的斜率值位於第一斜率值及第二斜率值之間時，則保持目 前連動狀態中第一馬達及第二馬達的轉速；第三，當第一 馬達及第二馬達兩者轉速的斜率值小於第二斜率值時，代 表驅動對焦鏡組的第二馬達轉速過快，此時，連動控制器 會控制第二馬達暫時停止，待第一馬達驅動縮放鏡筒使第 一馬達及第二馬達兩者轉速的斜率值介於第一斜率值及第 二斜率值時，再啟動第二馬達使對焦鏡組繼續進行位移。 另一方面，第一馬達及第二馬達驅動縮放鏡筒及對焦 鏡組由展開至收納的過程，連動控制器控制的方法則與上 述判斷條件相反，在此不予贅述。 以下將揭露本揭示内容之一實施例，藉此說明本揭示 201250330 内容上述實施方式之鏡頭連動防撞方法，確實具有所需要 的物理特性。應瞭解到，在以下敘述中，已經在上述實施 方式中提到的要件將不再重複贅述，僅就需進一步界定者 加以補充。 表一是本揭示内容一實施例的位移步數表。在此由表 一的左至右分別列出當中各字詞所代表之具體意義：pos 為縮放鏡筒的計算步數；+A為縮放鏡筒的控制步數； inf-stopper為遠端攝影機構的停止點；inf-limit為遠端攝影 機構作動的極限值；inf-position為對焦鏡組作動領域的中 心步數；建議曲線為規晝對焦鏡組的移動步數；near-limit 為近端攝影機構作動的極限值；near-stopper為近端攝影機 構的停止點。 NO zoom-pas AF棚領域 FOCUS 里動獅ϋ lable P〇S +A uxistoppei inf-limit Inf-Rasitinii 锂謀袖锘 jiBu-limit neu-stoppez 可觔範固 中心肪 1 LimitCNeax) -1447+A -1337 -662 -727 -727 -727 -727 -750 -66 -716 里觔 2 S •1315+A 4205 -&S2 •727 -72?

[Embodiment] FIG. 1 is a functional block diagram of a lens interlocking anti-collision device according to an embodiment of the present disclosure. As shown in FIG. 1, the lens linkage anti-collision device 1 201250330 includes an optical module 110, a driving module 120 and a linkage controller 130. The linkage controller 130 controls the driving module 120 to control the collision of the internal components of the optical module 110 by means of a slope linkage. The optical module 110 includes a zoom lens barrel 111 and a focus lens group 112. The focus lens group 112 is located in the zoom lens barrel 111, and the user can change the position of the focus lens group 112 in the zoom lens barrel 111 to change the focal length and achieve the effect of focusing on an object. The driving module 120 is configured to drive the optical module 110 to be displaced. The driving module 120 includes a first motor 121 and a second motor 122. The first motor 121 is used to drive the zoom lens barrel 111 to perform axial expansion and contraction. The second motor 122 is used to adjust the position of the focus lens group 112 in the zoom lens barrel 111. The linkage controller 130 is configured to control the first motor 121 and the second motor 122 to interlock with each other, and control the rotation speed of the first motor 121 to be proportional to the rotation speed of the second motor 122. In the present embodiment, the first motor 121 and the second motor The speed of 122 is proportional to the linear relationship. In this way, during the interlocking process of the zoom lens barrel 111 and the focus lens group 112, since the linkage controller 130 adjusts the rotation speeds of the first motor 121 and the second motor 122 with time, there is no zoom lens barrel 111. And the situation in which the focus lens group 112 collides with each other. As to how the linkage controller 130 adjusts the rotational speeds of the first motor 121 and the second motor 122, the details of this portion will be described in the subsequent lens linkage anti-collision method 300. FIG. 2 is a functional block diagram of a lens interlocking anti-collision device according to an embodiment of the present disclosure. As shown in FIG. 2, the lens linkage anti-collision device 200 includes a zoom lens barrel 210, a focus lens group 220, a first motor 230, a 201250330 second motor 240, and a linkage controller 250. The linkage controller 250 controls the first motor 230 and the second motor 240' to control the collision of the zoom lens barrel 210 with the focus lens group 220 by means of a slope linkage. The focusing lens group 220 is located in the zoom lens barrel 210, and the first motor 230 is connected to the zoom lens barrel 210, and drives the zoom lens barrel 21 to perform axial expansion and contraction displacement. The second motor 240 is connected to the focusing lens group 220, and the focus is adjusted. The mirror set 220 is in a position to zoom in the lens barrel 210. The linkage controller 250 is configured to control the first motor 230 and the second motor 240 to interlock with each other and control the rotation speed of the first motor 230 to be proportional to the rotation speed of the second motor 240. In the present embodiment, the first motor 230 and the second motor The speed of 240 is proportional to the linear relationship. In this way, the zoom lens barrel 210 and the focus lens group 220 are in the process of interlocking. Since the linkage controller 250 adjusts the rotational speeds of the first motor 230 and the second motor 240 over time, there is no zoom lens barrel 210. And the case where the focusing mirror group 220 collides with each other. As for how the linkage controller 250 adjusts the rotational speeds of the first motor 230 and the second motor 240, the details of this portion will also be described in the subsequent lens linkage anti-collision method 300. FIG. 3 is a flow chart showing the steps of the lens interlocking collision avoidance method according to another embodiment of the present disclosure. As shown in Fig. 3, the lens interlocking collision avoidance method 300 of the present embodiment includes at least the following steps: First, a first motor is selected as shown in step 31A to drive a zoom lens barrel for axial telescopic displacement. Further, as shown in step 320, a second motor is selected to adjust the position of the pair of focal lengths in the zoom barrel. Then, as shown in step 330, a first slope value of both the first motor and the second motor is converted to the 201250330 speed when the zoom lens barrel is chased by the focus lens group. Next, as shown in step 340, a second slope value of the rotational speeds of both the first motor and the second motor when the focusing lens group collides with the zoom lens barrel is calculated. Finally, as shown in step 350, the first motor and the second motor are controlled by a linkage controller such that the slope values of the two rotational speeds are between the first slope value and the second slope value. In short, the linkage controller monitors the first motor and the second motor separately with time, calculates the slope value of the two rotation speeds at any time, and controls the first motor and the second motor respectively according to the calculated slope value drop point. Rotating speed. Specifically, the first motor and the second motor can drive the zoom lens barrel and the focus lens group from the storage to the deployment process, and are divided into the following three cases: First, when the slopes of the first motor and the second motor are rotated When the value is greater than the first slope value, the first motor that drives the zoom lens barrel rotates too fast. At this time, the linkage controller controls the second motor to rise to the highest speed to avoid colliding the zoom lens barrel and the focus lens group; Secondly, when the slope values of the rotational speeds of the first motor and the second motor are between the first slope value and the second slope value, the rotational speeds of the first motor and the second motor in the current interlocking state are maintained; When the slope value of the rotational speeds of the first motor and the second motor is less than the second slope value, the second motor that drives the focus lens group rotates too fast. At this time, the linkage controller controls the second motor to temporarily stop. When the motor drives the zoom lens barrel so that the slope values of the rotational speeds of the first motor and the second motor are between the first slope value and the second slope value, the second motor is activated to continue to shift the focus group. On the other hand, the first motor and the second motor drive the zoom lens barrel and the focus lens group from the development to the storage process, and the method of controlling the interlocking controller is opposite to the above-described determination condition, and will not be described herein.

The scale of the zoom lens barrel in Table 1 ranges from -876 steps to 110 steps, and the step range of the focus mirror group ranges from -727 steps to 512 steps. The slope relationship diagram shown in Figure 3 can be drawn, and then Further calculated the slope to be 0.793. In the present embodiment, the focus lens group is driven by a stepping motor, and the zoom lens barrel is driven by a DC motor. The manner in which the number of steps is calculated and the difference therebetween will be described below. 201250330 First, the number of steps of the focusing mirror group is driven by a 1-2 phase method of 9 degrees per step. The so-called 1 step, that is, 1-2 phase driving is called a phase change; this stepping motor step feedback detection method is The number of steps sent internally by the FW is calculated. On the other hand, when the number of steps of the zoom lens barrel is driven by the DC motor, the light-shielding blade is rotated to allow the encoder to count the PI to quickly block the light, and the H/L waveform of the fast change is used as the step feedback detection, PI The waveform is triggered by a positive/negative edge of one cycle and is counted up to 2 steps. Figure 5 shows the _-series diagram of the zoom lens barrel and the focus lens group in Figure 4. As shown in Figure 5, the zoom lens barrel (3G, 5G) is a linkage mechanism. As long as the DC motor is driven, the zoom lens barrel (3G, 5G) will be linked to the fixed groove track on the lens' and the focus lens group (4G) ) It is driven by another stepping motor, so the control mechanism of the zoom lens barrel and the focus lens group are separated separately, and the focus lens group is in the middle of the zoom lens barrel. At the same time, the zoom lens barrel needs to be monitored at any time. And the speed of both the focus lens group to avoid the collision of the focus lens group (4G) and the zoom lens barrel (3G, 5G). In addition, during the process of driving the focal lens group and zooming the lens barrel, when the focusing lens group is driven too fast or the zoom lens barrel is driven too slowly, the zoom lens barrel (3 (}, 5g) tracking focus lens group will occur ( In the case of 4G); conversely, when the focus group is driven too slowly, or when the zoom mirror is driven too fast, the focus lens group (4g) will collide with the zoom lens barrel (3G, 5G). For the above reasons, In this embodiment, it is necessary to continuously calculate and monitor the slope of the zoom lens barrel and the focus lens group during driving. To calculate the design value of the zoom lens barrel (3G, 5G) in FIG. 5, calculate the focus mirror group (4G) for driving. The driving curve of the time and the reference slope of the linkage between the two, wherein the relationship between the slopes of the linked reference is as follows: Scale the number of steps of the lens barrel - zoom the lens barrel, start the snippet group § the number of steps - focus ^ 201250330 linkage reference slope = Then, after starting the drive, in order to avoid collision during the operation, the present embodiment performs real-time monitoring in the following relationship: 'the number of target steps of the shrink tube_the zoom lens barrel', the target number of steps of the focus mirror group- The current number of steps in the focus group will be detailed below. The method for maintaining the interlocking slope without colliding during the interlocking process in the embodiment is described in detail. The process of driving the zoom lens barrel from expansion to storage is taken as an example to illustrate: 1. Firstly formulate the upper and lower limit slopes: the present embodiment uses the reference slope + -10% as the upper and lower limits. 2. Processing method when the upper limit slope is greater than: The zoom lens is relatively slow at this time. 'First stop the focus group or increase the voltage of the drive lens to accelerate to avoid the focus lens. The group chasing the zoom lens tube occurs. 3. The processing mode below the lower limit slope: This means that the zoom lens barrel is faster, and the focus lens group can be accelerated or reduced by the zoom lens driving voltage to decelerate to avoid scaling. The case where the lens barrel collides with the focus lens group occurs. 4. The process of storing the lens barrel from the storage end to the unfolding process is the reverse of the above situation, and therefore the above calculation method may be reversely processed. In the example, the range of SOHP is the relevant mechanism position from the storage state to the power-on state. Because the zoom lens barrel (3G, 5G) shares the drive source and is synchronously driven, 3G (inf-limit) and 5G (near-limit) The block is the movable range of the focusing mirror group (4G), and the focusing mirror group (4〇) needs to be activated in this interval when it is turned on and cannot collide with the zooming lens barrel (3G, 5G). Because of the 4G (focusing lens group) active field center The number of steps is not a simple and single-slope line segment, so the single slope of the proposed curve (as shown in Figure 4) is used as the driving method to simplify the control method and achieve the collision prevention effect. The above embodiment shows that the application The lens linkage anti-collision device and the method thereof of the disclosure, the linkage controller ensures the gap between the zoom lens barrel and the focus lens group during the interlocking process by the slope linkage, and the linkage controller monitors and calculates the first motor at any time and The slope value of the rotation speed of the second motor prevents the rotation speed of any of the motors from being too fast or too slow, so that the situation that the zoom lens barrel and the focus mirror group collide with each other can be effectively avoided.
