Visubit "ai+3d vision" product series | loading assembly workstation

Automobile manufacturing is one of the industries with the highest degree of Automation , But automobile OEMs 、 More than half of the loading and unloading of parts factories 、 The assembly process is manual , Work hard 、 High repeatability 、 Recruitment difficulties ; And because there are thousands of kinds of auto parts 、 The deviation of manual feeding leads to irregular incoming materials, which makes the traditional automation unable to cope with the flexible production mode , More and more automobile OEMs and parts manufacturers began to layout AI Visual intelligence loading and unloading 、 Assembly robots .

Loading and unloading of auto parts 、 assembly

Visual recognition pain points

In the actual production process , Auto parts include exterior parts 、 Interior trim 、 Engine accessories 、 Different types of power train accessories , Their shapes are different and their sizes vary greatly .

Loading and unloading of most auto parts 、 Manual operation is adopted for assembly , And rely on “AI Machine vision ” And “ Industrial robot ” Loading and unloading of parts in combination 、 The assembly has the following pain points ：

► There are many kinds of parts ： The wide variety of parts makes it impossible to grasp through simple suction cups and fixtures , It is not allowed to scratch or scratch the surface of parts during grasping , Therefore, it is necessary to specially design flexible fixtures and realize grasping with ultra-high visual recognition accuracy in a specific attitude ;

► Part reflection 、 Easy to deform ： The exterior decoration parts are mostly high reflective parts , Yes 3D Visual imaging and recognition are easy to cause interference , And it is easy to deform in the process of grasping , It is very difficult for robots to place fixtures or assemble ;

► The position of incoming materials is unstable ： Manual material placement deviation 、 Accuracy deviation of hopper car 、AGV Feeding deviation will lead to great changes in the incoming position and attitude of parts ,AI It is more difficult to locate parts by machine vision ;

► High placement accuracy is required ： After blanking, parts shall be subject to multiple assembly processes , It needs to be placed on the blanking fixture with a very accurate attitude , The deformation of parts leads to the error of robot placement .

Core strengths

► Initiate 3D Registration cloud algorithm

The first groundbreaking will Transformer The network is applied to 3D Point cloud processing , Realization Efficient real-time point cloud registration algorithm ; Through this registration algorithm , The accurate posture of the part to be grasped can be obtained , Provide high-precision grasping information and placement information for the robot ; Besides , Point cloud registration algorithm based on deep learning network , have Strong anti-interference ability 、 High stability 、 Strong real time Characteristics , And for the missing point cloud caused by part reflection , There is a certain degree of compatibility .

► be based on 3D High precision positioning and grabbing of point cloud

The 3D model of the part is accurately registered with the 3D point cloud photographed in real time , It can guide the robot to accurately grasp the highly reflective parts stacked in the material box ; Besides , The robot driver independently developed by visual bit can plan the robot trajectory in real time , In the deep 1.5m While grasping the parts in the material frame , Actively avoid the metal column fixing the workpiece and the four walls of the material box , In this process, the visual recognition accuracy can reach 0.1mm~0.2mm.

△ Point cloud imaging effect

△ Point cloud extraction effect

△ Point cloud matching effect

△ Accurately grasp the real object with deep frame

► be based on 3D High precision correction and placement of point cloud

utilize 3D The recognition and location algorithm realizes the inverse operation of the grasping process , The parts on the robot end fixture shall be installed according to the process requirements Place exactly In the fixture , And the parts are processed with high precision 3D rectifying , The visual recognition accuracy of this process can also reach 0.1mm~0.2mm.

The application case

Batch landed in a future factory of auto parts

In the black light factory of a leading auto parts enterprise , Dozens of them AGV、 Industrial robots work together to complete the exterior decoration of many models “ Automatic injection molding —AGV Transport — Set up a warehouse for temporary storage —AGV Transport — Visual loading and unloading — Automatic assembly — Quality testing — Packing ” Fully automated production . Most of the exterior ornaments are highly reflective 、 Deformable plastic parts , And the automatic production line must be compatible with the flexible production of parts of different specifications .

In the black light factory , Independent research and development workstation （SpeedLoader-M） It realizes the Multiple specifications 、 High reflection 、 Large deformation Accurately identify and grasp the exterior trim of the , Re pass 3D Visual finish with high accuracy 3D Place it in the secondary fixture after correction . Besides , Automated production lines can be based on MES Place orders and switch to automatic production and assembly of different products accurately and quickly , In a real sense Realize flexible production .
