Example Embodiment

[0005] Specific implementation mode one: refer to figure 1 , This embodiment is composed of a left linear guide 1, a right linear guide 5, a left mobile platform 2, a right mobile platform 6, a driving device, a left link 4, and a right link 8. The driving device is the left linear motor A and the right linear motor B arranged in parallel, and the stator guide rail A of the two linear motors 1 And B 1 That is, the left linear guide 1 and the right linear guide 5, the left mobile platform 2 and the right mobile platform 6 are respectively fixedly connected to the movers A of the two linear motors 2 And B 2 Up; one end of the left link 4 and the right link 8 are respectively connected to the left mobile platform 2 and the right mobile platform 6 through the first rotating pair 3 and the second rotating pair 7, and the other of the left link 4 and the right link 8 One end is connected to each other through the end rotating pair 9.

Example Embodiment

[0006] Specific implementation mode two: refer to figure 2 The difference between this embodiment and the first embodiment is that the driving device consists of a left screw C provided on the left linear guide rail 1 and the right linear guide rail 5. 1 And right screw C 2 , The left slider D matched with the left and right screws respectively 1 And the right slider D 2 , The left motor E that drives the left and right lead screws to rotate 1 And right motor E 2 Composition, the left mobile platform 2 and the right mobile platform 6 are respectively installed on the left slider D 1 And the right slider D 2 on. In this embodiment, the motor drives the lead screw to rotate, and the left and right platforms are linearly moved by the sliding block, and the linear motion of the platform is transformed into a two-dimensional plane motion at the end of the link. The other composition and connection relationship are the same as in the first embodiment.

It includes mutually parallelly-arranged left straight-line guideway and right straight-line guideway, left moving platform and right moving platform which are respectively arranged on the left straight-line guideway and right straight-line guideway and can make straight-line movement along the guideway, drive device for driving left moving platform and right moving platform and left link and right link, one end of left tank and right link can be respectively connected with left moving platform and right moving platform by means of first turning pair and second turning pair, and their another ends are mutually connected by means of tail end turning pair.

Description

technical field [0001] The invention relates to an industrial robot, in particular to a two-degree-of-freedom plane moving robot. Background technique [0002] Existing high-speed, high-precision robot mechanisms have the following motion forms: (1) XYTable workbench mode: due to the heavy load of the motor on the base, the linear motion inertia is large, so the speed and acceleration of the system are restricted; in addition, the effective load of the system and The total load ratio is low, resulting in a large waste of electric energy. (2) Multi-joint parallel linkage mechanism driven by a rotating motor: the inertia of the multi-link mechanism is large, which is not conducive to further improvement of the system speed; at the same time, it also brings large deformation of the joint bearing, which reduces the positioning accuracy of the entire mechanism. Contents of the invention [0003] In order to solve the problems existing in the prior art, the present invention pr...
