借助 2D 摄像头进行取放作业

机器人辅助取放通常用于生产、组装和包装过程,在这些过程中,需要精确识别、抓取物体以供进一步加工,然后将物体放到另一位置。通过 2D 摄像头对物体进行定位,摄像头将位置数据直接发送给机器人。

使用机器视觉设备取放 – 优点

摄像头安装方式灵活

没有两个相同的应用!根据应用情况,可以将机器视觉硬件静态安装在抓取区域上方或直接安装在机械手臂上。摄像头的静态安装特别适用于空间紧张的应用或安装空间有限的小型机械手臂,将摄像头安放在机械手臂上可以提高应用的灵活性。

摄像头与机器人直接通信

2D 摄像头通过机器人视觉接口直接与制造商 UR、 KUKA 和 ABB 的机器人通信 – 无需开发自己的接口,也不必连接单独的硬件。每种类型的机器人都有示例程序或 UR 的 URCap 以供下载。这样可以非常简便快速地设置机器人视觉应用 – 无论是使用 B60 Smart Ca­me­ra 还是带有机器视觉照相机的机器视觉控制器。记录的 TCP/IP 通信可与其他制造商连接。
 

Seam­less In­te­gra­tion into the uni­Vi­sion Ecosys­tem

The wen­glor uni­Vi­sion 3 tool­box of­fers va­rious mo­du­les for ob­ject de­tec­tion, such as the mo­du­les for lo­ca­li­za­tion and pat­tern mat­ching. Both mo­du­les enable dif­fe­rent ob­ject types to be taught in, whe­reby se­ve­ral – even dif­fe­rent – ob­jects can be found in both mo­du­les and sor­ted, for exam­ple, by po­si­tion. Va­ria­ble off­sets in x and y can also be im­ple­men­ted, which in­crea­ses the fle­xi­bi­lity of the pick-​and-place ap­pli­ca­tion enor­mously: De­pen­ding on the ap­pli­ca­tion, it is thus pos­si­ble to spe­cify the exact point at which the robot should grab the ob­ject – at the tip, in the midd­le or rather at the rear. The re­sults, such as the grip­ping po­si­tion or the con­to­ur of the de­tec­ted ob­ject, can be dis­pla­yed in­di­vi­dually and fle­xibly in the web-​based vi­sua­li­za­tion.

Re­du­ced Cycle Times Thanks to Multi-​Object Re­cor­ding

In wen­glor uni­Vi­sion 3 soft­wa­re, se­ve­ral – even dif­fe­rent – ob­jects can be de­tec­ted with a sin­gle image cap­tu­re and their coor­di­na­tes can be pas­sed on to the robot con­trol sys­tem. This means that the robot can grip the ob­jects di­rectly one after the other without ha­ving to move to the de­tec­tion po­si­tion for ca­me­ra cap­tu­re again be­fo­re each grip. This re­du­ces cycle time and greatly in­crea­ses the ef­fi­ciency of the pick-​and-place ap­pli­ca­tion. 

Pre­ci­se Ca­li­bra­tion with Ac­cu­ra­te Ca­li­bra­tion Tar­gets

The 2D ca­me­ra and robot must initially be ca­li­bra­ted once. Highly ac­cu­ra­te ca­li­bra­tion tar­gets are avai­la­ble in va­rious sizes and ma­te­rials (glass for trans­mit­ted light ap­pli­ca­tions, car­bon fiber for in­ci­dent light ap­pli­ca­tions). The suc­cess­ful ca­li­bra­tion pro­cess can be chec­ked di­rectly via a ve­ri­fi­ca­tion step.

Pick and Place ver­sus Bin Pic­king – What is the Dif­fe­ren­ce?

Pick and Place: Pre­ci­se Lo­ca­li­za­tion and Pic­king

In pick-​and-place ap­pli­ca­tions, 2D ca­me­ras lo­ca­te the ob­jects to be pic­ked and pass their po­si­tion coor­di­na­tes on to the robot con­tro­ller. The robot can then pick the ob­jects pre­ci­sely and then place them in a dif­fe­rent po­si­tion.
Pick and place is sui­ted for sim­ple and quick ap­pli­ca­tions where the ob­jects are se­pa­ra­ted and on one level. 
 

Bin pic­king: Reaching into a Bin

Bin pic­king re­fers to an au­to­ma­ted ap­pli­ca­tion, where ro­bots pick ran­domly arran­ged ob­jects from con­tai­ners. This re­qui­res 3D sen­sors that de­tect the po­si­tion of the ob­jects in the space and pass the in­for­ma­tion to the robot.
Bin pic­king with 3D sen­sors is ideal if the ob­jects are not se­pa­ra­ted and are arran­ged in ran­dom po­si­tions.
