Problems solved by technology

[0003] However, although friction at the screw-fastened portion can be suppressed by introducing a seal 4' such as fluorinated rubber between the robot arm 1' and the dust cover 3', the followability is low due to the high resilience of the fluorinated resin. , so when the mechanical arm 1' moves, due to the deformation of the mechanical arm 1', a gap G will be generated between the seal 4' and the mechanical arm 1' ( figure 1 The gap G in is shown enlarged for illustration only, and does not represent the actual size), thereby reducing the sealing effect and causing problems such as particle falling at the gap G

Abstract

A sealing structure includes: a mechanical arm of a robot; the dustproof cover covers the mechanical arm and is fastened on the mechanical arm through a fastener; the sealing piece is clamped between the mechanical arm and the dustproof cover, and comprises a low-resilience material, an elastic material and an elastic material; and a film surrounding at least the outer peripheral surface of the low-resilience material. According to the sealing structure provided by the invention, the sealing performance between the mechanical arm and the dustproof cover can be ensured even when the mechanical arm of the robot acts.

Description

technical field [0001] The invention relates to a sealing structure, in particular to a sealing structure for a robot. Background technique [0002] Such as figure 1 As shown, in a robot used for handling large-sized workpieces such as liquid crystal panels, a dust cover 3' made of aluminum or the like is usually covered on the hollowed-out mechanical arm 1' of the robot by fastening screws 2' to prevent The mechanical arm 1' is scratched by the workpiece, etc., while preventing dust and the like from entering the hollowed-out internal space of the mechanical arm 1'. In addition, in the prior art, a sealing member 4' such as fluorinated rubber is usually sandwiched between the mechanical arm 1' and the dust cover 3' to further improve the dustproof effect, and at the same time protect the parts where the screws are fastened . [0003] However, although the friction at the screw-fastened part can be suppressed by introducing a seal 4' such as fluorinated rubber between the...
