Problems solved by technology

For example, U.S. Patent No. 7,178,981 uses sensors to sense the force change between the end cover and the slider, but because sensors are required at both ends, and the end cover itself has a certain rigidity, it is not practical. Easy and accurate sensing of problems with end caps

Embodiment Construction

[0029] The applicant first explains here that throughout the specification, including the embodiments described below and the claims, terms related to directions are based on the directions in the drawings. Secondly, in the embodiments to be described below and in the drawings, the same component numbers represent the same or similar components or their structural features.

[0030] see figure 1 , figure 2 and Figure 4 , The linear slide rail 10 of the first embodiment of the present invention includes a track 20 , a slider 30 , a first end cover 40 , a second end cover 50 , a plurality of balls 60 , and two force sensors 70 .

[0031] The two opposite sides of the rail 20 respectively have two vertically opposite outer rolling grooves 22 .

[0032] The slider 30 has a first end surface 31, a second end surface 32 opposite to the first end surface 31, and a chute 33 passing through the first end surface 31 and the second end surface 32. The slider 30 is provided on the ra...

Abstract

The present invention relates to a linear slide rail, which includes a track and a slider. The slider is arranged on the track and forms a load channel with the track. The slider itself has two non-load channels. In addition, the two sides of the slider The opposite end faces are respectively provided with a first end cover and a second end cover. The first end cover itself has two first return channels. The second end cover has a return assembly and a sealing piece. The return assembly has two second return channels. , The load passage, the non-load passage, the first return groove and the second return groove jointly form a circulation passage for the ball to run, and a force sensor is arranged between the return flow component and the sealing sheet. Therefore, the linear slide rail of the present invention utilizes the rigidity difference between the first end cover and the second end cover together with the force sensor to determine whether there is any abnormality in the running of the balls.

Description

technical field [0001] The invention relates to a linear slide rail, in particular to a linear slide rail capable of detecting abnormal backflow conditions. Background technique [0002] The traditional linear slideway includes a track and a slider sliding on the track, wherein an end cover is provided at the front and rear ends of the slider, so that the track, the slider and the two end covers jointly form a A pair of circulation channels for multiple balls to run. [0003] In order to ensure the smooth running of the balls, sensors have been used in the prior art to detect whether there is an abnormal backflow condition. For example, U.S. Patent No. 7,178,981 uses sensors to sense the force change between the end cover and the slider, but because sensors are required at both ends, and the end cover itself has a certain rigidity, it is not practical. Easy and accurate sensing of problems with end caps. In addition, the Japanese patent JPA_2012193803 places the sensor ou...
