Description
本發明係與捲線器有關,特別是指可確保長度計算正確的一種具有計算纜線使用長度功能之捲線器。 The present invention relates to a cord reel, and more particularly to a cord reel having the function of calculating the length of use of a cable to ensure correct length calculation.
按,習知之捲線器,大多僅提供捲線及放線的效果,並不提供拉出長度計算的功能。 According to the conventional reel, most of them only provide the effect of winding and unwinding, and do not provide the function of pulling out the length calculation.
我國公告第M409047號專利,即揭露了一種具有計算收放線長度的內視鏡,其主要是利用二個接收元件來對應設置於其支撐架上的支撐條,並在線輪之一側盤面上設置一發射元件,藉由線輪轉動時發射元件隨之轉動,在經過接收元件時使其接收到該發射元件所發射的訊號,藉以偵測轉動的圈數,並藉由兩個接收元件來判斷該線輪的轉動方向。 China Patent No. M409047 discloses an endoscope having a calculation length of a retractable wire, which mainly uses two receiving elements to correspond to a support bar disposed on a support frame thereof, and is disposed on one side of the wire wheel. a transmitting element, wherein the transmitting element rotates when the wire wheel rotates, and receives the signal emitted by the transmitting element when passing the receiving component, thereby detecting the number of revolutions and determining by the two receiving components The direction of rotation of the reel.
然而,前述的習知技術,在計算使用長度(例如伸出長度或縮回長度)時有著長度計算不正確或精準度不高的問題。在正常狀況下,收線或捲線是持續動作,此時發射元件會正常的通過該二接收元件而判斷圈數及方向。然而,當使用者在捲線及收線的動作之間猶豫時,其動作產生往復性時,即可能發生發射元件在線輪順時針轉動至使一個接收元件接收到信號後,線輪又逆時針轉動至使另一個接收元件收到信號,此時,系統即會誤判該線輪為順時針轉動,進而誤判圈數及方向。此外,由於前述的習知技術僅使用一個發射器,因此其長度的精準度而言只能計算出線輪轉 動的圈數,因此其計算的單位長度較大,無法計算較精準的長度。 However, the aforementioned prior art has a problem of incorrect length calculation or low precision when calculating the length of use (for example, the extension length or the retraction length). Under normal conditions, the take-up or winding is continuous, and the transmitting component will normally pass the two receiving components to determine the number of turns and direction. However, when the user hesitates between the winding and the take-up action, when the action is reciprocating, it may happen that the transmitting element rotates clockwise when the wire rotates clockwise until the receiving component receives the signal, and the wire wheel rotates counterclockwise. So that the other receiving component receives the signal, at this time, the system will misjudge the reel to rotate clockwise, and then misjudge the number of turns and direction. In addition, since the aforementioned prior art uses only one transmitter, the accuracy of the length can only calculate the line rotation. The number of laps is dynamic, so the unit length of the calculation is large, and the more accurate length cannot be calculated.
此外,依據前述習知技術之專利說明書可知,其顯示長度乃是藉由內視鏡之纜線連接於內視鏡本身之主機來提供顯示功能,捲線器本身並不具有顯示長度的功能。因此,習知技術必須選擇能配合顯示長度的內視鏡才能使用,其用途受到了極大的限制。 In addition, according to the patent specification of the prior art, the display length is a display function by connecting the cable of the endoscope to the host of the endoscope itself, and the cord reel itself does not have the function of displaying the length. Therefore, the prior art must select an endoscope that can match the display length to be used, and its use is greatly limited.
本發明之主要目的在於提供一種具有計算纜線使用長度功能之捲線器,其可準確的判斷使用長度。 SUMMARY OF THE INVENTION A primary object of the present invention is to provide a cord reel having a function of calculating the length of use of a cable, which can accurately determine the length of use.

The grounding is provided on the reel 21. In the present embodiment, the magnetic blocks 24 are exemplified by four.
該可撓纜線31,捲繞於該線輪21。為了圖式表示上的方便, 本發明僅於第1圖中顯示該可撓纜線31,於其他圖式中不予顯示。 The flexible cable 31 is wound around the reel 21. For the convenience of the graphical representation, The present invention only shows the flexible cable 31 in Fig. 1, which is not shown in other drawings.
該等霍爾元件41,係直接或間接設於該架體11,並且對應於該等磁性塊24隨著該線輪21轉動時之運動路線而等距排列,又該三霍爾元件41依其排列順序由第一個至第三個的距離係小於相鄰的二該磁性塊24的距離。於本實施例中,該等霍爾元件41係排列呈弧狀。 The Hall elements 41 are directly or indirectly disposed on the frame body 11 and are arranged equidistantly corresponding to the movement paths of the magnetic blocks 24 as the wire wheel 21 rotates, and the three Hall elements 41 are further The distance from the first to the third in the order of arrangement is smaller than the distance between the adjacent two of the magnetic blocks 24. In this embodiment, the Hall elements 41 are arranged in an arc shape.
該計算及顯示裝置51,設於該架體11且電性連接於該等霍爾元件41,該計算及顯示裝置51具有一顯示幕52朝向外側。於本實施例中,該計算及顯示裝置51具有一微控制單元54,電性連接於該等霍爾元件41以及該顯示幕52。此外,該計算及顯示裝置51具有複數按鍵56,電性連接於該微控制單元54,藉此可提供使用者輸入之介面,而可供使用者操作設定或歸零等基本控制動作。於本實施例中,該等霍爾元件41係設於該計算及顯示裝置51的內部,而間接地設於該架體11。 The computing and display device 51 is disposed on the frame 11 and electrically connected to the Hall elements 41. The computing and display device 51 has a display screen 52 facing outward. In the present embodiment, the computing and display device 51 has a micro control unit 54 electrically connected to the Hall elements 41 and the display screen 52. In addition, the computing and display device 51 has a plurality of buttons 56 electrically connected to the micro-control unit 54, thereby providing a user-input interface for the user to operate a basic control action such as setting or zeroing. In the present embodiment, the Hall elements 41 are disposed inside the computing and display device 51 and are indirectly disposed on the frame 11.
以上說明了本實施例之架構,接下來說明本實施例之操作狀態。 The architecture of this embodiment has been described above, and the operational state of this embodiment will be described next.
請參閱第1~3及5圖,由於該三霍爾元件41由第一個至第三個的距離係小於相鄰的二該磁性塊24的距離,因此可以確保不會同時有兩個磁性塊24對應於該等霍爾元件41。在使用時,使用者拉出或縮回該可撓纜線31時,即會帶動該線輪21轉動,進而使得該等磁性塊24不斷的經過該三霍爾元件41,進而測得該線輪21的轉動角度及方向。其中,由於本發明係設置複數磁性塊24(本實施例中以4個為例),因此每感測到一個磁性塊24,即代表轉動的角度為90度,換算為該可撓纜線31捲繞於該線輪21之單圈長度後即可獲得較習知技術更為精準的長度結果。而該微控制單元54即主要負責接收 該三霍爾元件41所感測到的訊號,在加以判斷及計算後將結果顯示於該顯示幕52上,藉以讓使用者判讀。又,使用者可以在該可撓纜線31拉出一段長度後,操作該計算及顯示裝置51使其歸零,之後再繼續使用該可撓纜線31,而可達到歸零後重新計算使用長度的效果。 Referring to FIGS. 1 to 3 and 5, since the first to third distances of the three Hall elements 41 are smaller than the distance between the adjacent two magnetic blocks 24, it is ensured that there is no two magnetic simultaneously. Block 24 corresponds to the Hall elements 41. When in use, when the user pulls out or retracts the flexible cable 31, the reel 21 is driven to rotate, so that the magnetic blocks 24 continuously pass through the three Hall elements 41, thereby measuring the line. The angle of rotation and direction of the wheel 21. Wherein, since the present invention is provided with a plurality of magnetic blocks 24 (four in the embodiment), each of the magnetic blocks 24 is sensed, that is, the angle of rotation is 90 degrees, which is converted into the flexible cable 31. Winding around the length of the single turn of the reel 21 results in a more accurate length result than conventional techniques. The micro control unit 54 is mainly responsible for receiving The signal sensed by the three Hall elements 41 is displayed on the display screen 52 after being judged and calculated, so that the user can interpret the signal. Moreover, the user can operate the computing and display device 51 to zero after the flexible cable 31 is pulled out for a length, and then continue to use the flexible cable 31, and can be recalculated after returning to zero. The effect of the length.
本發明所使用的三個霍爾元件41,可以確保方向的偵測不會錯誤。其原因在於,當只有兩個霍爾元件41感測到有磁性塊24時而另一個霍爾元件41沒有感測到磁性塊24時,即代表線輪21沒有旋轉或是正在往復運動,只有三個霍爾元件41均依序感測到磁性塊24時,才可以算得上是確定的動態,而可以做為計算長度的依據。藉此可以計算出正確的長度,亦改善了習知技術有可能誤算長度的缺失。 The three Hall elements 41 used in the present invention ensure that the direction detection is not erroneous. The reason is that when only two Hall elements 41 sense the magnetic block 24 and the other Hall element 41 does not sense the magnetic block 24, it means that the wire wheel 21 does not rotate or is reciprocating, only When the three Hall elements 41 sense the magnetic block 24 in sequence, it can be regarded as a certain dynamic, and can be used as a basis for calculating the length. By this, the correct length can be calculated, and the loss of the length of the miscalculated length of the prior art is also improved.
此外,藉由該計算及顯示裝置51設於該架體11上,可以達到讓使用者直接檢視使用長度的效果。由此可知本發明無須另行連接可以顯示長度的設備,應用的層面將可更為廣泛。 Moreover, by providing the calculation and display device 51 on the frame body 11, the effect of allowing the user to directly view the length of use can be achieved. It can be seen that the invention does not need to be connected to a device capable of displaying the length, and the application level can be more extensive.
值得一提的是,前揭實施例中的磁性塊24雖以間接設置於該線輪21為例說明,然而,該等磁性塊24亦可直接設置於該線輪21,而同樣具有隨著線輪之轉動而旋轉的效果。又,前揭實施例中的霍爾元件41雖以間接設置於該架體11為例說明,然而,該等霍爾元件41亦可以直接設置於該架體11,同樣可以具有偵測磁性塊24之效果。 It should be noted that the magnetic block 24 in the foregoing embodiment is illustrated by being indirectly disposed on the reel 21, however, the magnetic blocks 24 may be directly disposed on the reel 21, and have the same The effect of the rotation of the reel. Moreover, the Hall element 41 in the foregoing embodiment is described as being indirectly disposed on the frame body 11. However, the Hall element 41 may be directly disposed on the frame body 11, and may also have a detection magnetic block. 24 effect.
此外,還有需補充的一點是,如第6圖所示,該計算及顯示裝置51可更增加一無線傳輸模組58,而電性連接於該微控制單元54。藉此,可無線連接於其他主機,例如本發明配合使用於內視鏡時,即可無線連接於一內視鏡主機(圖中未示),藉以計算內視鏡纜線的使用長度,除了可在該 顯示幕52上顯示使用長度之外,也可將計算所得的結果經由該無線傳輸模組58傳送至該內視鏡主機,進而由該內視鏡主機來顯示長度。其中,該無線傳輸模組58之規格可為W-i-Fi、藍牙(Blue Tooth)或RF射頻。由此可知,藉由該無線傳輸模組58,可提供以無線方式將長度資訊向外傳送至配合之主機,而可達到除了在該計算及顯示裝置51本身顯示長度資訊之外,更可在其他主機上顯示長度資訊的效果,進而讓使用者在使用上更為方便。 In addition, it should be added that, as shown in FIG. 6, the computing and display device 51 can further add a wireless transmission module 58 and be electrically connected to the micro control unit 54. Thereby, it can be wirelessly connected to other hosts. For example, when the present invention is used together with an endoscope, it can be wirelessly connected to an endoscope main body (not shown) to calculate the length of use of the endoscope cable, in addition to Can be in In addition to the length of use displayed on the display screen 52, the calculated result may also be transmitted to the endoscope host via the wireless transmission module 58, and the length may be displayed by the endoscope host. The specification of the wireless transmission module 58 can be W-i-Fi, Bluetooth (Blue Tooth) or RF radio. It can be seen that, by the wireless transmission module 58, the length information can be wirelessly transmitted to the matching host, and the length information can be displayed in addition to the length information displayed in the computing and display device 51. The effect of length information is displayed on other hosts, which makes the user more convenient to use.
