Description

Linear motor guide device {Guide device of Linear Motor}

The present invention relates to a linear motor guide device applied to a working robot, and more specifically, the deflection of the linear motor stator, the linear motor mover, and the main cover coupled to the main base to protect the LM rail and the LM block. It is to provide a linear motor guide device that can provide a wide range of stroke and operation safety by providing a non-contact structure without any contact, and to provide lubricating oil to the LM rail and the LM block without removing the main cover.

Linear motor (LM) guide devices are widely used as devices that can be mounted on a working robot (not shown) to enable precise reciprocation.

However, the conventional LM guide device has a problem that sag due to the load of the device itself when a long distance is used, and there is also a problem that it is inconvenient to mount the LM guide device to the working robot.

In this regard, the present inventors have researched and developed a linear motor guide device capable of eliminating the above problems.

In other words, the linear motor guide device 100, which the inventors have previously applied for registration (Korean Utility Model Registration No. 0368400), can be easily mounted on an existing working robot, and the longitudinal section of the device is increased so that sag does not occur even during use. At the same time, the longitudinal stiffness has been strengthened to cope with torsion and warpage.

Looking at the configuration thereof, two or more LM block 190 is coupled to the main base 140 for supporting each component to be mounted as shown in Figure 1, and the LM rail 184 fixed to the main base 140 ) And a linear motor stator (182) symmetrically installed on the main base (140) and the sliding table (130) so as to transfer the reciprocating transfer means combined with the sliding table (130) coupled to the lower side. ) And a main cover having both ends supported by side covers 122 and 124 positioned above the reciprocating transfer means and coupled to both ends of the main base 140. 110, wherein the main base 140 has a symmetrical formation of the upper protrusion partition 142 when viewed in a cross-section to actively cope with torsion and bending phenomena, and the LM rail 184 Combined To prevent entry of foreign matter into the drive means from the side is provided on the center side of the main base 140 is able to provide a safety operation.

The pre-registered linear motor guide device 100 configured as described above exhibits excellent performance in strokes within 3M.

However, when the stroke is longer than 3M (for example, 4M or more and 50M), the main table 110 and the sliding table 130 carried by the reciprocating means are rubbed to cause abnormal noise, and the friction surface is shaved particles. When the main cover 110 is separated and configured, the joint part of the main cover 110 is not precise, so that the sliding table 130 is operated at a high speed (1M or more per second) and the sliding table 130 is separated. Friction of the main cover 110 may cause equipment damage.

In addition, since polluting the clean environment due to the friction caused by the friction between the main cover 110 and the sliding table 130, and has a large vulnerability in the clean environment, such as semiconductor equipment, LCD, PDP manufacturing equipment, long stroke At the distance (more than 3M), the above-mentioned content is not applicable, and even if applied, it does not have the above-mentioned problem.

Recently, the linear robot has been used a lot due to the trend toward larger home appliances, especially LCD and PDP. However, due to the problems described above, application is limited.

As a temporary measure, a block or roller made of Teflon material or MC material is attached to the contact surface of the main cover 110 and the sliding table 130, but it is also used as a contact structure without the above-mentioned fatal problem. It is only a temporary measure.

Meanwhile, the reciprocating means consisting of a combination of the LM rail 184 fixed to the main base 140 and the LM blocks 190 coupled to the lower side of the sliding table 130 is sealed by the main cover 110 and is lubricated. Since the oil supply nipple 250 is configured to inject the lubricating oil in a state in which the main cover 110 is completely removed when the lubricating oil is periodically supplied to the reciprocating transfer means in order to minimize the frictional force of the reciprocating transfer means. There was a hassle to supply.

The present inventors have devised the present invention in a non-contact manner to eliminate all the problems that the conventional linear motor guide device 100,

In the present invention, the lower side of the sliding table 130 is configured to be opened, and the main cover 110 is supported by supporting the lower side of the main cover 110 with the support 310 fixed to the main base 140 through the open side. The main cover 110 and the sliding table 130 is rubbed to cause abnormal noise by allowing the main base 140 to always maintain a predetermined distance irrespective of the sliding table 130 moved by the reciprocating means. Particles with friction surfaces are generated, and when the main cover 110 separated into several parts is used, the non-contact method of the conventional problems, such as inaccurate joints, causes equipment damage during high-speed driving (more than 1M per second). To the LM rail 184 and the LM block 190 constituting the reciprocating transfer means to the side of the sliding table 130, by configuring an oil supply nipple 250 The present invention has been completed with the technical problem of devising in order to easily supply lubricating oil when necessary without the separation of the main cover 110.

That is, in the present design, the main cover 110 supported by the side covers 122 and 124 coupled to both ends of the main base 140 is formed by forming the coupling space 300 inside the sliding table 130. In addition, an opening 301 is formed below the coupling space 300, and the upper cover of the support 310 having the lower side fixed to the main base 140 is inserted into the opening 301 to cover the main cover 110 and the bolt. Fix it with the fixing means of. The support 310 is preferably installed at approximately 1 ~ 2M intervals with the neighboring support 310.

The support 310 and the main cover 110 may be directly coupled to both members, but the support plate 302 is coupled to the lower side of the main cover 110 when considering the deflection or bending of the main cover 110. It is preferable to combine using.

The main cover 110 may be a long one, such as the main base 140, but may be divided into 2 to 3M in consideration of convenience, such as maintenance.

The upper side of the LM rail 184 is fixed to the main base 140 to supply lubricating oil to the LM rail 184 and the LM block 190 constituting the reciprocating transfer means on the side of the sliding table 130 and The oil supply nipple 250 is coupled to the oil passage 251 through the oil passage 251.
