2, four shaft industrial robots start to automatically grab tyre surface, if detecting does not have tyre surface on current hinge, automatically Hinge is opened, next layer of tyre surface is grabbed.

3, robot catching robot is mounted with 14 groups of vacuum absorption devices, catches and tire is sucked using vacuum chuck after tyre surface It simultaneously lifts in face.

4, it using the multi-joint characteristic of industrial robot, is placed on the rack of turn-over rig, places after grabbing tyre surface Frame is driven by the rotation of shaft to realize tyre surface turn-over, is then put tyre surface to conveying device；

5, it is issued and is instructed by PLC, the first block roller mounting bar and the first block roller mounting bar close up, and makes during tyre surface returns.

6, tyre surface Gui Zhonghou, tyre surface head are forwarded to the first inspection positions, and the second detection support drives the second inspection It surveys sensor to start to move, detect the tail portion of tyre surface and records walking displacement, obtain the physical length of tyre surface.

7, during tyre surface is bonded, assembly drum fitting speed is adjusted according to the length of tyre surface in real time and tyre surface is fed speed Speed difference between degree realizes that tread joint correctly docks.

8, during being bonded, 16 pressure areas of pressure point of multi-disc pressure roll press tyre surface, according to the tyre surface of different size The pressure value for pre-setting each pressure area automatically switches as formula.Each of the binding face of realization tyre surface and lower Flour product Contact position perfect can be bonded.

It should be pointed out that above embodiments are only the representative examples of the utility model.The utility model can also there are many Deformation.All essence any simple modification, equivalent change and modification to the above embodiments according to the utility model, It is considered as belonging to the protection scope of the utility model.
