Description
本發明是有關於一種線性傳動裝置,且特別是有關於一種可即時監控潤滑油量的線性傳動裝置。The present invention relates to a linear transmission device, and in particular to a linear transmission device capable of real-time monitoring of lubricating oil quantity.
線性傳動裝置,例如滾珠螺桿或線性滑軌,因具有極佳的機械傳動效率,而被廣泛應用在各種需要精密移動的機具上。然而,線性傳動裝置的元件之間需要充分的潤滑,否則易因彼此摩擦而造成磨損,從而縮短其使用壽命。Linear actuators, such as ball screws or linear slides, are widely used in various machines that require precise movement due to their excellent mechanical transmission efficiency. However, sufficient lubrication is required between the components of the linear transmission, otherwise they are prone to wear due to friction with each other, thereby shortening their service life.
中華民國專利公告第I359237號專利案揭露一種滾珠螺桿潤滑感測裝置,其係在螺帽外接二電線,所述二電線構成導電迴路,且所述二電線透過螺帽、滾動元件及螺桿產生一接觸電阻,當附著於滾動元件表面的油膜消失時,導電迴路形成通路而啟動警示裝置,藉以提醒操作人員補充或更換潤滑油。然而,前述專利案的周邊設備較複雜,且其偵測機制易受工作環境如切削液、切屑之影響而不準確。The Republic of China Patent Publication No. I359237 discloses a ball screw lubrication sensing device, which is connected to two wires outside the nut. The two wires form a conductive circuit, and the two wires pass through the nut, the rolling element and the screw to generate a Contact resistance, when the oil film attached to the surface of the rolling element disappears, the conductive circuit forms a path and activates the warning device to remind the operator to replenish or replace the lubricating oil. However, the peripheral devices in the aforementioned patents are relatively complex, and their detection mechanism is easily affected by the working environment such as cutting fluid and chips and is inaccurate.
美國專利公告第US 6216821 B1號專利案揭露一種滾珠螺桿潤滑裝置,其係利用含有潤滑油的聚合物部件與螺桿的外徑部分可滑動地接觸,藉以防止附著在螺桿之螺紋槽的潤滑油被刮除,從而使潤滑油可維持在螺桿之螺紋槽。然而,前述專利案缺乏偵測及回饋潤滑油剩餘量的機制,當潤滑油剩餘量不足或耗盡時,使用者無法即時獲知,而不利於保養與維護。U.S. Patent No. US 6216821 B1 discloses a ball screw lubricating device, which uses a polymer part containing lubricating oil to slidably contact the outer diameter of the screw, so as to prevent the lubricating oil attached to the thread groove of the screw from being Scraping, so that the lubricating oil can be maintained in the thread groove of the screw. However, the aforementioned patents lack a mechanism for detecting and feeding back the remaining amount of lubricating oil. When the remaining amount of lubricating oil is insufficient or exhausted, the user cannot know immediately, which is not conducive to maintenance and maintenance.
隨著線性傳動裝置所應用的產業,如半導體或自動化產業,已進入或正邁向無人化工廠的規模,如何在無人環境下有效地監控線性傳動裝置的潤滑油量,以適時進行排程保養,避免線性傳動裝置因潤滑不足而縮短使用壽命,遂成為相關業者努力的目標。As the industries where linear actuators are applied, such as the semiconductor or automation industries, have entered or are approaching the scale of unmanned chemical factories, how to effectively monitor the amount of lubricating oil in linear actuators in an unmanned environment, so as to schedule maintenance in a timely manner , To avoid the shortened service life of the linear transmission device due to insufficient lubrication, it has become the goal of the relevant industry.

步驟311中,參考溫度可依據線性傳動裝置10的工作溫度範圍以及所欲達到的精準度進行選擇。例如,線性傳動裝置10的工作溫度範圍為30
oC~70
oC,可選擇此溫度範圍中每隔20度的溫度點做為參考溫度,即30
oC、50
oC、70
oC等3個溫度點作為參考溫度。又例如,可選擇此溫度範圍中每隔10度的溫度點做為參考溫度,即30
oC、40
oC、50
oC、60
oC、70
oC等5個溫度點作為參考溫度。參考溫度之間的溫度間隔越小,精確度越高。依據本發明一實施方式參考溫度之間的溫度間隔為10
oC。
In
關於步驟312,配合參照第8圖,其是依據本發明一實施方式之計算含油單元150對應各參考溫度於單位時間的釋油率的步驟流程圖,其包含步驟316~318。步驟316是量測含油單元150於各參考溫度的一初始重量;步驟317是經過一預定時間後量測含油單元150於各參考溫度的一釋油後重量;步驟318是依據初始重量、釋油後重量及預定時間計算得到各參考溫度於單位時間的釋油率。例如,步驟316中,量測含油單元150於30
oC的初始重量為Wi克,步驟317中,於30
oC經過1小時後量測含油單元150的釋油後重量為Wf克,步驟318中,含油單元150在30
oC於每分鐘的釋油率為(Wf-Wi)/60,單位為克/分鐘(g/min)。當含油單元150包含固體潤滑材151及導引部152時,由於潤滑油是由固體潤滑材151提供,導引部152本身不會消耗,含油單元150對應各參考溫度於單位時間的釋油率也可視為是固體潤滑材151對應各參考溫度於單位時間的釋油率。由前述計算方式可知,本發明之「釋油率」是指單位時間的釋油率,為簡明起見,有時簡稱為釋油率。藉由步驟312,可求出含油單元150對應不同參考溫度於單位時間的釋油率,亦即可建立含油單元150之參考溫度與釋油率的資料庫。

步驟313是將步驟312得到的數據進行進一步處理,以獲得擬合方程式。擬合方程式可依據多項式、最小平方法、回歸分析等原理進行計算。此外,擬合方程式可利用已知的計算軟體如Excel計算得到。Step 313 is to further process the data obtained in
換句話說,依據本發明的釋油模型,可以是步驟312所得到的參考溫度與釋油率的資料庫,也可以將資料庫的數據進行擬合而得到的擬合方程式。釋油模型可作為估算含油單元150中潤滑油的剩餘量的依據。In other words, the oil release model according to the present invention can be the database of reference temperature and oil release rate obtained in
請復參照第6圖,步驟330中,潤滑油的剩餘量的計算方式如下:假設潤滑油的剩餘量為W2、潤滑油的初始重量為W1,參考溫度t的釋油率為R
t,釋油時間為T,則可依據式(I)得到潤滑油的釋油量M,可依據式(II)得到潤滑油的剩餘量:
M = R
t×T …….(I);
W2 = (W1-M) …….(II);
其中W1、W2、M的單位可為重量單位,例如克(g);R
t的單位可為重量單位/時間單位,例如克/分鐘(g/min);T的單位可為時間單位,例如分鐘(min)。
Please refer to Fig. 6 again, in
以下將實際舉例說明步驟320、330。請參照表一,其係使用第1圖至第4圖之線性傳動裝置10、固體潤滑材151的黏度為68 cst,依據步驟311、312所得到的釋油模型,在此釋油模型為參考溫度與釋油率的資料庫。
假設第6圖的偵測頻率是1次/min,即控制單元220每分鐘進行一次步驟320,當步驟320的當下溫度是40
oC,則由表一可知,釋油率R
40為3.0141 × 10
-4g/min,以二次偵測的時間間隔作為釋油時間,在此為1 min,依據式(I)、(II)可得到潤滑油的釋油量M = 3.0141 × 10
-4g/min× 1 min、潤滑油的剩餘量W2 = W1-3.0141 × 10
-4g/min× 1 min。潤滑油最一開始的初始重量可預先量測得到,例如,可先量測全新未使用過之含油單元150的重量,再量測使用過且潤滑油皆已釋出之含油單元150的重量,二者的差值即為潤滑油最一開始的初始重量(即線性傳動裝置10運作0分鐘時潤滑油的重量),將其代入式(I)中的W1,則可計算出線性傳動裝置10運作1分鐘後潤滑油的剩餘量。進行第二次偵測時(即線性傳動裝置10運作第2分鐘的開始),以線性傳動裝置10運作1分鐘後的潤滑油的剩餘量作為第二次偵測時潤滑油的初始重量,再依據式(I)、(II)分別計算潤滑油於第2分鐘的釋油量及剩餘量,則可計算出線性傳動裝置10運作2分鐘後潤滑油的剩餘量,依此類推,可計算出線性傳動裝置10每多運作1分鐘其潤滑油的剩餘量。
Assuming that the detection frequency in Figure 6 is 1 time/min, that is, the
假設控制單元220所接收的當下溫度,資料庫中缺乏對應的釋油率,可利用內插法或外插法計算其對應釋油率。例如,步驟320的當下溫度是42.5

(IV)。
For another example, the current temperature in
計算出釋油率後,即可代入式(I)、(II)計算出潤滑油的剩餘量。After the oil release rate is calculated, it can be substituted into formulas (I) and (II) to calculate the remaining amount of lubricating oil.
請參照第9圖,其是依據本發明一實施方式之參考溫度與釋油率的關係圖,其係以表一之數據作圖而成,透過觀察法判定該釋油率與溫度曲線近似二次多項式,並可依據步驟313得到如式(V)的擬合方程式。先假設
,依序代入30、50、70度時之溫度點:
並解出a、b、c得擬合方程式如下:
y= 1.1451×10
-6x
2– 6.1049×10
-5x + 9.1827×10
-4…………(V);
式(V)中,y為釋油率,x為參考溫度/當下溫度。將步驟320得到的當下溫度代入式(V)中的x,即可得到對應當下溫度的釋油率,再代入式(I)、(II)可計算出潤滑油的剩餘量。依據本發明一實施例,依據式(V)的擬合方程式所計算的釋油率為1.502%,而實際釋油率為1.15%,二者差值為0.352%。顯示本發明可準確估計釋油率,進而可準確估算潤滑油的剩餘量,而可有效監控線性傳動裝置10的潤滑油量。

請復參照第6圖,步驟340是輸出剩餘量,即控制單元220將剩餘量傳送至訊號接收裝置230。步驟350是判斷剩餘量是否小於一閾值,閾值係預先設定,例如閥值可為0克或潤滑油最一開始的初始重量的10%。當剩餘量小於閾值時,表示潤滑油耗盡或即將耗盡,此時進行步驟360,控制單元220發出一警示訊號,警示訊號可為一聲音訊號及/或光訊號,此時,訊號接收裝置230可配置有聲音模組及/或光模組,以發出聲音訊號及/或光訊號;當剩餘量大於或等於閾值時,表示潤滑油足夠,回到步驟320,繼續進行偵測。步驟350及步驟360為選擇性地步驟,在其他實施方式中,當不包含步驟350、360,執行完步驟340即回到步驟320。另外,釋油模型可預先建立,一旦釋油模型建立好,之後的偵測可直接由步驟320開始進行。Please refer to FIG. 6 again, step 340 is to output the remaining amount, that is, the
