Problems solved by technology
On the one hand, interference between sheet metal parts and the robot body is prone to occur in certain postures; on the other hand, when bending sheet metal parts of different lengths (usually the length range is 400-2500mm), it is necessary to adjust the distance between the robot and the bending machine. position, distance, which necessitates the installation of additional travel axes
The solution of additional shaft increases the complexity of the system and increases the cost

Embodiment Construction
[0034] In order to make the object, technical solution and advantages of the present invention clearer, various embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.
[0035] A first embodiment of the present invention relates to a bending robot. The bending robot is used in conjunction with the bending machine 9 (bending knife 91) to bend the sheet metal part 8 to be bent, and its structure is as follows: figure 1 As shown, it specifically includes: a base 1 , a cantilever 2 , a big arm 3 , a forearm 4 ...

The invention relates to the industrial automation field, and discloses a bending robot. The bending robot is matched with a bending machine and used for bending a to-be-bent sheet metal component, and comprises a base, a cantilever, a big arm, a front arm, a wrist joint and a clamp, wherein the cantilever is connected with the base by use of a first shaft, and rotatably connected with the big arm by use of a second shaft; the big arm is rotatably connected with the front arm by use of a third shaft, and the front arm is rotatably connected with the clamp by use of the wrist joint; the size of the bending robot needs to satisfy a certain condition. The bending robot in the embodiment of the invention can realize the bending operation only needing five shafts; not only is the cost of the robot for the bending operation lowered, but also can be the operation finished more flexibly without any auxiliary facilities.
Description
technical field [0001] The invention relates to the field of industrial automation, in particular to a bending robot. Background technique [0002] Sheet metal bending operations are in great demand. Taking an elevator as an example, the length of the door panel is about 2200mm, the width is about 500-600mm, and the weight of the door panel is about 20kg. If it is manually fed, lifted, and unloaded, the labor intensity is very large. [0003] At present, there are already many plans to replace manual bending with general-purpose six-joint industrial robots. A robot with a load of 50kg is generally used. But the inventor of the present invention found that: since the general-purpose 50kg robot is mainly used for operations such as handling, assembly, and grinding, the design of its connecting rod parameters is not suitable for bending operations. On the one hand, interference between sheet metal parts and the robot body is prone to occur in certain postures; on the other h...
