Description

Linear Guide Apparatus The present invention relates to a linear guide device, and more specifically, to a linear guide device that moves a transport object in a straight line to a specific position. Generally, a linear guide device is a device that moves a transport object in a straight line to a specific position, and consists of a guide rail and a guide block installed on the guide rail so as to be movable in the longitudinal direction of the guide rail. The above linear guide device can linearly transport the transport target to a specific position by coupling the transport target to the guide block and moving the guide block along the longitudinal direction of the guide rail. Korean Patent Publication No. 10-2428204 (August 4, 2022) (hereinafter referred to as the “prior art”) discloses a “linear motion guide device,” which is a linear guide device. The above-described prior art comprises a guide rail extending in one direction and having rail grooves formed on both sides along its length, a sliding block having a guide groove formed to be coupled to the guide rail and sliding grooves of a circulating structure formed on both sides forming the guide groove, and a plurality of balls that rotate and circulate while rolling by the sliding block installed in the sliding groove and moving along the guide rail, wherein when the sliding block is viewed from the axial cross-section of the guide rail, the sliding groove comprises a first passage formed at a position facing the rail groove and a second passage located above the first passage, so that the balls circulate in the vertical direction, wherein the first passage is open toward the rail groove and includes an inclined surface on the inside in which the width gradually decreases in the direction opposite to the direction toward the rail groove from the open outer side, thereby making two-point contact with the balls in the vertical direction, and the sliding block reciprocates along the guide rail and includes a main body that fixes and supports a transfer equipment, a pair of end covers coupled to both ends of the main body, and an elastic structure on the main body that wraps around the end covers. The elastic fixing clip is configured to form a connection, wherein the elastic fixing clip is characterized by being composed of an elastic body that wraps around all three sides in the circumferential direction of the end cover, and an elastic fastening part that extends from one bent side and the other end of the elastic body and forms an elastic locking part that is fastened to the main body. In a linear guide device including a plurality of balls as in the above-mentioned prior art, a large amount of heat is generated due to friction during the circulation of the plurality of balls. In this case, the movement of the sliding block must be stopped until the generated heat cools down in order to prevent damage to the linear guide device. However, the aforementioned conventional technology had a problem in that it was difficult to determine whether the heat was generated because a means for detecting the heat was not installed.
