Problems solved by technology

However, the flexible wrist for robots designed with helical springs has the following disadvantages: due to the fixed structure of the helical springs, the flexible central position of the flexible wrist device formed by the helical springs is limited, and the linear displacement and angular error compensation capabilities are also very limited. Therefore, Difficult to appl

Example Embodiment

[0034] Below, in conjunction with accompanying drawing and specific embodiment, the present invention is described further:

[0035] like figure 1 The shown flexible unit for precision assembly of industrial robots includes a strip-shaped flexible body 11, and a plurality of slots 12 are opened on the side of the flexible body 11, and each slot 12 is along the length direction of the flexible body 11. interval distribution.

[0036] The flexible body 11 can be made of metal material, and the number of slots 12 and the extending directions of the slots 12 can be set correspondingly according to the design requirements of flexibility. In order to make the flexible unit 10 have uniform flexibility in all directions, the following settings can be made in this example:

[0037] The slots 12 are alternately distributed on opposite sides of the flexible body 11 . The distances between adjacent slots 12 are equal, the slot widths of each slot 12 are equal, and the slot depths of ea...

Abstract

The invention discloses a flexible unit for industrial robot precision assembly. The flexible unit comprises a strip-shaped flexible body. The side of the flexible body is provided with a plurality of cutting grooves. All the cutting grooves are distributed at intervals in the length direction of the flexible body. The invention further discloses a flexible wrist adopting the flexible unit and used for industrial robot precision assembly. By means of the flexible unit and the flexible wrist, larger flexible deformation can be provided in the linear displacement and angle direction, and therefore a large linear displacement and angle direction error is compensated for; the cost is low and the service life is long.

Description

technical field [0001] The invention relates to a mechanical wrist, in particular to a flexible unit for an industrial robot and a flexible wrist for compensating assembly errors for the precision assembly of an industrial robot. Background technique [0002] In the robot automatic assembly operation, due to the repeatable positioning accuracy error of the robot and the material delivery system, the tolerance of the fixture and the processing tolerance of the parts, etc., there will be assembly errors (including linear displacement direction and angular direction) between the parts to be assembled. , and the assembly accuracy between the parts to be assembled is generally high, especially in the fields that require precision assembly such as 3C (computer, and communication consumer electronics equipment), which makes the robot unable to complete the assembly task. Therefore, robotic automated precision assembly systems must include devices to eliminate assembly errors. [0...
