This oscilloscope complicates the construction of the lubrication state detecting device. Even if you look at the waveform displayed on the oscilloscope, it is difficult to judge whether the lubrication state is good. = Most of the consoles are equipped with a plurality of motion guides, and the components of the obedience are also, and the ▲ has a number of moves. The screw skirt used for the screw is also assembled on the workbench. Since the lubrication states of the moving blocks or nuts are different, it is desirable to detect the lubrication state for each moving block or nut. SUMMARY OF THE INVENTION It is therefore an object of the present invention to provide a lubrication state detecting apparatus and method for visually and simply detecting the lubrication state of each moving block or nut. 97103659 200902869 In addition, the factor determining the life of the motion guiding device depends not only on whether there is metal contact between the rolling elements and the rolling contact surface of the body, but also the time during which the rolling elements and the rolling elements are in metal contact. The time accumulated by the metal contact has elements that determine the life of the motion guide. Accordingly, it is another object of the present invention to provide a lubrication state detecting apparatus and method which can detect the cumulative time during which the rolling elements form a metal contact with the rolling element rolling contact surfaces. More progress, § When using a liquid lubricant, the film becomes thicker when the speed of the moving block is large, and the film becomes thinner when the speed is small. The thickness of the oil film formed between the rolling elements and the rolling contact surface of the rolling body depends on the speed of the moving block. Further, the resistance value between the rolling body and the rolling contact surface of the rolling element also varies depending on the type of the liquid lubricant. When a solid lubricant is used as the lubricant, if the type of the solid lubricant/monthly agent or the film thickness is changed, the resistance value of the rolling elements and the rolling contact surface of the rolling elements also differs. Even with good lubrication, the resistance values will vary depending on the condition of the motion-guided farm or screw unit. A still further object of the present invention is to provide a lubrication state detecting device and method which can set an appropriate resistance limit value according to the speed of the motion guide and the screw device, and the condition of the fourth (4).

加電壓’電流會在工作台9或基座中流通。為防止此現 象，在移動塊1之上面與工作台9之間、或執道滑執2之 下面與基座之間設置絕緣片丨5，使運動導引裝置3絕緣 於工作台9或基座。 縱使藉由使絕緣片15移動塊丨及執道滑執2間絕緣， =若將移動塊1及軌道滑執2安裝於工作台9及基座的螺 柽未經絕緣，則移動塊1與工作台9、執道滑軌2與基座 間會透過螺栓而導通。為防止此種現象，如圖7所示，使 移動塊1的安裝孔1c之周圍由絕緣體丨6構成。而且，如 圖8所示，軌道滑軌2的安裝孔2b之周圍亦由絕緣體17 構成。 圖9表示在移動塊1之上面安裝工作台9的例子。於工 作台9加工沉頭孔9a。於沉頭孔9a中插入螺栓，藉由將 螺检螺合於移動塊1之安裝螺紋，而將工作台9安裝於移 動塊1。為防止螺栓與工作台g間之導通，於沉頭孔之座 面9c設置有絕緣墊圈18。其中，僅利用絕緣墊圈i 8即 可防止移動塊1與工作台9間經由螺栓之導通。然而，當 97103659 19 200902869 螺栓周圍與工作台9相接觸時，僅利用絕緣墊圈Μ便無 法充分絕緣。因此，有必要在移動塊丨的安裝螺紋1c : 周圍設置絕緣體16。 當使用液體狀之潤滑油作為潤滑劑之情況下，在移動塊 1停止時，滾動體12與滾動體滚走溝la、2a之間不會形 成油膜，滾動體12與滾動體滾走面之間形成金屬接^ / 因此，移動塊1與執道滑執2之間的電阻值成為零，移動 塊1發紅色光。當移動塊i產生動作而速度加快時，則在 滾動體12與滾動體滚走溝la、2a之間形成油膜，滾動體 12與滾動體滾走溝la、2a成為絕緣狀態。因&，移動塊 1與執道滑執2之間的電阻值大於極限值，移動塊！發綠 色光。發明者由實驗確認到若去除運動導引裝置3之全邻 潤滑油’則即便使移動塊！高速移動，移動塊i之m ^ 保持為紅色。亦即’可知並非因移動塊i之高速移動而使 滾動體12與滾動體滾走溝la、2“，成為絕緣狀態，而是 因滾動體12與滾動體滾走ha、2a之間存在有油膜而使 滾動體12與滾動體滾走溝la、2a間成為絕緣狀態。 當使用液體狀之潤滑油時，形成於滾動體12與滾動體 滾走溝la、2a之間的油膜厚度，依移動塊}之移動速度、 潤滑油之種類而異。最適當之油膜厚度亦依移動塊丨之移 動速度、潤滑油之種類而冑。由於不必切斷連接有可變雨 阻器之電路即可改變電阻之極限值，所以在實際使用運= 導引裝置3之狀況下可改變電阻之極限值。因此，可根據 移動塊1之移動速度、潤滑油之種類而設定最適當的極限 97103659 20 200902869 值。 亦有取代液體狀潤滑油而使用以二硫化鉬或ρπΕ為 $的固體财劑之情況。在真空環境等無法使用液體狀潤

The method for detecting the lubrication state of the invention according to the first aspect of the invention is that the moving block is movably assembled to the rail member through the rolling elements, and the rolling elements are rolled when the moving block relatively moves in the axial direction of the obstructing member. The moving motion guiding device or the nut is rotatably assembled to the screw device of the screw through the rolling element to detect the lubrication state thereof; the lubrication state detecting method includes the resistance value detecting step, and the obstructing member is Applying a voltage between the moving blocks or between the screw and the nut to detect a resistance value between the obstructing member and the moving block or between the screw and the nut; a limit value setting step by a variable resistor capable of changing a limit value of the resistor, setting a limit value of the resistor; and a comparing step of comparing the limit value set in the limit value setting step and the resistance value detected in the resistance value detecting step, generating The signal of the comparison result. (Effect of the invention) 97103659 12 200902869 According to the invention of the scope of the application of the patent application, the resistance value between the moving blocks of the obstructing member discs or between the screw and the nut is detected, and the detected resistance value is compared with the limit value. The hair element is illuminated according to the result of the comparison. The lubricating member is displayed by the moving member of the motion guiding device or the screw of the screw. The moving block or the nut can display the lubrication state during traveling. Therefore, 'the lubrication state of the moving block or nut can be easily judged by visual observation. According to the invention of claim 2, since the cumulative time of the metal contact between the rolling element and the rolling contact rolling surface can be detected, the life of the motion guiding device or the screw device can be accurately grasped. According to the invention of claim 3, since the limit value of the resistance is changed by the variable resistor, the optimum resistance value can be set in the case where the motion guiding device or the screw device is actually used. According to the invention of claim 4, the time at which the comparison means generates a signal can be accumulated. According to the invention of claim 5, it is possible to distinguish whether the detected resistance value is within the upper limit value and the lower limit value of the limit value.

According to the invention of claim 7, the lubrication state of the motion guiding device or the screw device can be detected. 97103659 13 200902869 According to the invention of claim 8 of the scope of the patent application, the resistance value between the obstructing member and the moving block or between the screw and the nut is detected, and the detected resistance value is compared with the limit value, according to the result of the comparison. The light emitting element is caused to emit light. Since the glazing element a is again a moving block of the motion guiding device or a nut of the screw device, the moving block or nut can display a lubrication state during travel. Therefore, the lubrication state of the moving block or the nut can be easily judged by visual observation. According to the invention of claim 9, the life of the motion guiding device or the screw device is detected due to the accumulation time of the metal contact between the rolling element and the rolling contact rolling surface. According to the invention of the first aspect of the patent application, since the limit value of the resistance is changed by the variable resistor, the most appropriate resistance value can be set in the actual use of the motion guiding device or the screw device. Hereinafter, an embodiment of the present invention will be described in detail with reference to the accompanying drawings, in which a resistance value detecting circuit for detecting a resistance value of a motion guiding device is shown. In the resistance value detecting circuit, a moving block of the motion guiding device 3 】 Applying a voltage between the obstructing member 2 to detect the resistance value between the moving block 1 and the obstructing member 2. A lubricant film is formed around the rolling member and the moving block. At the same time, the moving block and the obstructing member are insulated from each other. On the other hand, when no lubrication is formed around the rolling element, the rolling element forms a metal contact with the moving block i and the track member 2, so the resistance value is Zero. The resistor and the DC power supply are connected in series on the motion guiding device 3. The resistor R2 is connected in parallel on the motion guiding device 3. The detecting resistor R2 97103659 14 200902869 and the motion The electric power at both ends of the guiding device 3, as the motion guiding skirt 3, r=rR1, R2 and the direct current power source E constitute a resistance value detecting hand when a lubricant film is formed around the moving block 1 and the k-member The two are insulated, so the current does not flow into the motion guiding device 3. Therefore, the detected voltage VLM is a voltage generated only by the resistor R2. The voltage VLM is expressed by the following formula: (Formula 1) VLM = E1/( R1+R2)xR2 On the other hand, no lubrication is formed between the rolling elements and the rolling elements of the rolling elements, and the resistance of the motion guiding device disappears because the rolling elements form a metal connection with the moving block and the obstructing member 2. The detected voltage VLM is also zero. Depending on the formation of the lubricant film, the resistance value is accompanied by this, the voltage is changed from zero to the value calculated according to the formula i, the change of the VLM and the motion guiding device The change in the resistance value has a relative relationship. Therefore, the resistance value of the motion guiding device can be detected by the detection of the voltage. Fig. 2 and Fig. 3 show the circuit diagram of the lubrication state in the first embodiment of the present invention. A conceptual diagram representing the detection device, Figure 3 shows the details P circuit diagram. As described above, a resistor is connected in series with a resistor connected in series to the motion guiding device. The resistor R1 and the resistor R2 are connected in series with a DC power source, El. The motion guiding device 3 is connected. At both ends: the voltage signal is input as a comparison means comparator, 4. X, the limit value set by the variable resistor 5 as a limit value setting means is input to the comparator 97103659 15 200902869 4. The limit value is a voltage signal And is generated according to the resistance value set by the variable resistor 5. The comparator 4 compares the limit value set by the variable resistor 5 with the voltage of the motion guiding device 3, when the voltage signal of the motion guiding device 3 When it is greater than the limit value, a signal of the comparison result is generated. After the signal is inverted in the Ν〇τ circuit 6, the LEDs 7a and 7b (Ught emitting diodes) as light-emitting elements are input. The LEDs 7a, 7b are composed of, for example, a first LED 7b that emits green light [ribing and red light emission]. When the signal is generated by the comparator 4, that is, the detected voltage signal (resistance value) of the motion guiding device 3 is greater than the variable, the limit value set by the resistor 5, the green first LE]) 7a emits light, red The second LED 7b does not emit light. Conversely, when the comparator 4 does not generate a signal, that is, when the detected voltage signal (resistance value) of the motion director 3 is smaller than the limit value set by the variable resistor 5, the red second illumination *, , ' The green first LED 7a does not emit light. The end plate U including the LED 7a and the lubricating device embedded in the moving block i is simplified (refer to FIG. b) 〇=, and may be replaced by the first and second _& The red LED is illuminated, and the value is greater than the voltage signal of the field V (the resistance is reversed, the limit value set by the resistor 5 is not illuminated, the field is at the limit value. When the LED emits light, the red body of the S body 1 is red or green. When the lubrication state is good, the lubricant film is formed by the comparator 4 = 4 rolls. Therefore, the slip state is poor, and (4) the light is emitted. When the moving body forms a metal contact with the rolling contact rolling surface, the transmission value is zero. The comparator 4 does not generate a signal. Therefore, when the lubrication state is good, the moving block 1 moves when the sliding state is poor. Whether the lubrication state of the block 1 is good during the running is good. The moving block can easily determine that the signal generated by the comparator 4 can be output as a signal. The timing of the oil supply depends on the load condition of the motion guiding device 3. Different from the army. 'There is no direct relationship with the state of the lubricant film (oil film), therefore: there are too many or too little oil supply. In the current use of the motion guiding device 3, in order to prevent the oil film from being exhausted, the timing of the oil supply (four) will be moved. The shape is more practical and needs to be shorter. However, the use of the lubricant is increased, which is harmful to the environment. The oil supply pump is actuated by the signal generated by the comparator 4, and the oil supply pump is only used when the oil film is exhausted. Actuation or the like can be an oil supply method directly related to the state of the oil film. Therefore, an appropriate amount of the agent can be supplied at an appropriate timing. Fig. 4 shows a plurality of motion guiding device units mounted on the table 9. In this example, - Two roads 2 are arranged on the jade table 9 as the track member 2, and two moving blocks are assembled on each of the roads 2. Four moving blocks are mounted below the table 9 (4) The state varies depending on each moving block 1. Since the lubricating state detecting means 10 is provided in each moving block, each moving block 发 emits red or green light during traveling. Therefore, it can be judged separately for each moving block 1. Whether the lubrication state is good. Figure 5 A perspective view showing the motion guiding device 3. The motion guiding device 3 has a 97103659 17 200902869 long linear extending track rail 2, movably assembled to move: a moving block 1, and a rolling body interposed on the track rail 2 Rolling body...The rolling balls, rollers, etc. between the rolling elements of the rolling elements of the soil 1 are widely formed by a plurality of strips extending in the longitudinal direction, for example, four. The Annon hole 2b of the piece is moved by the counterbore. Block 1 is a saddle shape, which has a rolling body rolling groove la across the track, and the inner side shape of the disk block and the moving block 1 are opposite to each other. The rolling element in 9 is a moving body returning passage 1b, which is composed of two through-directions of the moving direction of the work 1; In the moving block direction conversion channel:: loading / end plate 11. The end plate 11 is provided with a U h and a rolling element returning passage lb=extending the rolling element rolling groove to return to the if lb, the direction/equal rolling body rolling groove 1a, and the rolling path. 11 Conversion track, which constitutes a cyclical rolling element cycle In the rolling element circulation path pinch, the moving body 12 can also be held by a plurality of rolling elements 12. Roll the string. When moving the block! When moving in a continuous direction with respect to the obstruction, the rolling element rolling on the axis rail 2 of the track slip 2 is moved, and the rolling element rolling the groove 1 a and the detour The rolling element of the sliding block 1 performs a rolling motion. Move to the top of the ball in the transition track, the ball in the direction of the end plate 11 97103659, and return from the opposite end 18 200902869 to the rolling element rolling surface of the moving block 1. Above the moving block 1, a mounting thread lc is machined for arranging the moving block into the table 9. Q 6 denotes a motion guiding device orthogonal to the axial direction of the track rail 2, and the table 9 is placed on the upper side of the moving block 1. The obstruction slide 1 is in contact with the base below. When the moving block 1 and the workbench 9, or the obedience (7) hold 2 and the base are turned on, if the block is moving! Applying a voltage 'current between the track slip 2 and the track slip 2 will flow through the table 9 or the pedestal. In order to prevent this, an insulating sheet 5 is disposed between the upper surface of the moving block 1 and the table 9, or between the underside of the obembark 2 and the base, so that the motion guiding device 3 is insulated from the table 9 or the base. seat. Even if the insulating sheet 15 is moved between the block 执 and the ruling slip 2, if the moving block 1 and the track slip 2 are attached to the table 9 and the shank is not insulated, the moving block 1 is The worktable 9, the rails 2 and the base are electrically connected by bolts. In order to prevent such a phenomenon, as shown in Fig. 7, the periphery of the mounting hole 1c of the moving block 1 is constituted by an insulator 丨6. Further, as shown in Fig. 8, the periphery of the mounting hole 2b of the rail slide 2 is also constituted by an insulator 17. FIG. 9 shows an example in which the table 9 is mounted on the moving block 1. The counterbore 9a is machined in the table 9. A bolt is inserted into the counterbore 9a, and the table 9 is attached to the moving block 1 by screwing the screw to the mounting thread of the moving block 1. In order to prevent conduction between the bolt and the table g, an insulating gasket 18 is provided on the seating surface 9c of the counterbore. Among them, the conduction between the moving block 1 and the table 9 via the bolt can be prevented only by the insulating spacer i8. However, when the bolt around 97103659 19 200902869 is in contact with the table 9, it is not possible to fully insulate it only by the insulating gasket. Therefore, it is necessary to provide the insulator 16 around the mounting thread 1c of the moving block. When a liquid lubricating oil is used as the lubricant, when the moving block 1 is stopped, an oil film is not formed between the rolling elements 12 and the rolling element rolling grooves la, 2a, and the rolling elements 12 and the rolling elements are rolled away. The metal connection is formed therebetween. Therefore, the resistance value between the moving block 1 and the ego lane 2 becomes zero, and the moving block 1 emits red light. When the moving block i is actuated and the speed is increased, an oil film is formed between the rolling elements 12 and the rolling element rolling grooves la and 2a, and the rolling elements 12 and the rolling element rolling grooves la and 2a are insulated. Because &, the resistance value between the moving block 1 and the embarrassing slip 2 is greater than the limit value, moving the block! Green light. The inventors have experimentally confirmed that even if the entire adjacent lubricating oil of the motion guiding device 3 is removed, even if the moving block is made! Moving at high speed, the m ^ of the moving block i remains red. In other words, it is understood that the rolling elements 12 and the rolling elements are not moved by the high-speed movement of the moving block i, and the rolling elements 12 and the rolling elements are in an insulated state, but there is a relationship between the rolling elements 12 and the rolling elements. The oil film is used to insulate between the rolling elements 12 and the rolling elements rolling grooves la and 2a. When a liquid lubricating oil is used, the thickness of the oil film formed between the rolling elements 12 and the rolling elements rolling grooves la and 2a is The moving speed of the moving block varies depending on the type of lubricating oil. The most suitable oil film thickness depends on the moving speed of the moving block and the type of the lubricating oil. Since it is not necessary to cut off the circuit to which the variable rain resistor is connected, The limit value of the resistance is changed, so that the limit value of the resistance can be changed in the actual use of the guide device 3. Therefore, the most appropriate limit can be set according to the moving speed of the moving block 1 and the type of the lubricating oil 97103659 20 200902869 There is also a case where a solid lubricant such as molybdenum disulfide or ρπΕ is used in place of a liquid lubricating oil, and a solid lubricant is used in a vacuum environment in which a liquid lubric/moon oil cannot be used. Solid run _ is covered by the rolling element 12 or the rolling element rolling grooves la, 2a by the scattering or the like. When the solid lubricating film is peeled off, it causes contact between the metals. The liquid lubricating oil can be replenished after the start of the operation, but the solid lubricant is It is impossible to re-coat. Since the solid lubricant is peeled off to reach the life of the motion guiding device, it is necessary to know the covering state of the solid lubricating film. The rolling guide 12 is covered with the solid lubricant. When the voltage is applied, the motion guiding device is insulated (ie, the green LED emits light) during the stop and movement of the moving block. After the solid lubricant is peeled off, the guiding device 3 is in the conducting state. The guiding device 3 is in an insulated state. The reason is that the solid lubricant has the function of an insulator. When the solid lubricant is peeled off, the motion guiding device 3 is turned on because the rolling body 12 and the rolling body roll away. 2a forms a metal contact. Therefore, the resistance value of the right detecting motion guiding device 3 is compared with the limit value, and it is also directly known whether the solid lubricant is peeled off. A circuit diagram of a lubrication state detecting device according to a second embodiment of the present invention. In the circuit towel of the present embodiment, time-dependent indicators of signals generated by the counting means 31, 32, and 33 are integrated, and when accumulated When the value is above the predetermined value, a signal is generated. The voltage signal at both ends of the motion guiding device 3 is input to the comparator 4. The comparator 4 compares the limit value set by the variable resistor 5 with the motion guiding device 3 97103659 21 200902869 The voltage signal 'when the voltage signal of the motion guiding device 3 is greater than the limit value, the signal of the comparison result is generated, and when the value is less than the limit value, no signal is generated. After the signal is inverted in the NOT circuit, the signal is input to the LED 7 and The AND circuit 32. When there is a signal input from the comparator 4, that is, when the comparator 4 determines that the lubrication is abnormal, the LED 7 emits red light. The photoelectric crystal outputs a signal to the outside when the lubrication is abnormal. The comparator 4 determines that the signal when the lubrication is abnormal is input to the aND circuit 32. Further, the pulse wave signal of a certain time interval generated by the pulse wave transmitter 33 and the external device synchronization signal are input to the AND circuit 32. The AND circuit 32 produces a pulse wave signal of the logical product of the signals. The pulse wave signal generated by the AND circuit 32 is input to the counter 31. The counter 31 outputs a lubrication abnormality warning signal when the count value reaches a predetermined value or more. The user of the motion guiding device 3 can confirm the lubrication state of the motion guiding device 3 after the lubrication state detecting device outputs the lubrication abnormality warning signal, supplying oil to the motion guiding device 3, supplying grease, or operating the fuel supply pump. Figure 11 shows a timing diagram of the signal. Comparator 4 produces the opposite comparator signal when the lubrication is abnormal and when the lubrication is normal. The pulse wave transmitter 33 generates a pulse wave signal for a certain time interval. The AND circuit 32 takes the logical product of the comparator signal and the pulse signal to produce a pulse signal to the counter. The counter 31 accumulates the pulse wave signal generated by the AND circuit 32 and sent to the counter, and outputs a warning signal when the accumulated value reaches a predetermined value (for example, 9) or more. Further, in the circuit diagram of the present embodiment, the time during which the signal of the lubrication abnormality is generated by the comparator 4 is replaced with a pulse wave signal, which is accumulated by the counter 31: 97103659 22 200902869, but the comparator 4 can be directly measured. The time to lubricate an abnormal signal. Further, during the period in which the comparator 4 generates a signal of the lubrication abnormality, that is, the signal indicating that the lubrication is normal is generated, the total time at which the lubrication abnormality signal is generated is accumulated. However, it is also possible to reset the accumulated value when the comparator 4 generates a signal indicating that the lubrication is normal. In this way, the motion guiding device with a higher stopping frequency can also correctly grasp the lubrication state. Fig. 12 is a circuit diagram showing the lubrication state detecting device according to the third embodiment of the present invention. In the circuit of the present embodiment, the first variable resistor 5-1 5 that sets the upper limit of the limit value and the second variable resistor 芎 5-2 ′ that sets the lower limit of the limit value are set as the limit value setting means. Further, the first comparator 4_丨 and the second comparator 4-2 are provided as comparison means. The voltage signals across the motion guiding device 3 are input to the first comparator 4-1 and the second comparator 4-2, respectively. The second comparator 4-2 compares the lower limit value of the limit value set by the second variable resistor 5_2 with the voltage signal of the motion guiding device 3, and generates a signal when the voltage signal is greater than the lower limit value of the limit value. When the voltage signal is less than the pole (the lower limit value is not generated, the signal is not generated. The first comparator 4-1 compares the upper limit value of the limit value set by the first variable resistor 5_丨 with the motion guiding device 3 The voltage signal generates a signal when the voltage signal is less than the upper limit value of the limit value, and vice versa, when the voltage signal is greater than the upper limit value of the limit value, the signal is not generated by the first comparator 4-1 and the second comparator 4_2, respectively. The generated signal is input to the AND circuit 19. The AND circuit 19 generates a signal when the first comparator 彳-丨 and the comparator 4-2 respectively generate a signal. After the signal is inverted in the NOT circuit 6, The LED 7a and the light-emitting element are input. 97103659 23 200902869 The LED is composed of a first LED 7a that emits green light and a second LED 7b that emits red light (a color different from the color emitted by the first LED 7a), and the first implementation described above. Form lubrication state detecting device phase In the lubrication state detecting device of the present embodiment, when the resistance of the motion guiding farm 3 is within the upper limit value and the lower limit value of the limit value, the green LED 7a having a good lubrication state is illuminated. When the resistance value of the lead device 3 is less than the lower limit value of the limit value or greater than the upper limit value, the red LEDn emits light. In order to make the lubrication state good, the film thickness of the lubricant also needs to be in the appropriate target circumference. The upper limit value and the lower limit value are used to determine whether or not the film is within an appropriate range.
