Problems solved by technology
[0002] In the existing commercial vehicle assembly line, the wheel assembly is done by manually operating the manipulator to grab the wheel, install the wheel and nuts on the wheel hub, and then tighten the wheel bolts with a tightening machine to complete the assembly. This process requires many workers. Participation is a huge labor cost for enterprises
[0003] There are many difficulties in using wheel and tire automatic assembly robots (referred to as wheel assembly robots) instead of manual wheel assembly. One of them is that because the company currently uses a ground drag chain trolley line, the travel speed of the plate chain is nonlinear and the accuracy lower
The wheel assembly robot must require the frame to travel at a continuous speed and with high precision when assembling the wheel. If the drag chain travels at a non-linear speed, it is difficult for the wheel assembly robot to accurately position the wheel for assembly, and it is impossible to achieve automatic wheel assembly.

Embodiment Construction
[0047] The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments.
[0048] see figure 1 As shown, the present invention proposes a high-precision vehicle frame traveling system that cooperates with the wheel assembly robot 80, including the drag chain trolley subsystem, the monitoring device 70, and the trolley subsystem. The ground drag chain trolley subsystem includes a ground drag chain 30 and a plurality of trolleys 40 that are dynamically connected to the ground drag chain 30 through bolts. The ground drag chain 30 is used to drive the plurality of trolleys 40 to transport the vehicle frame 50 . The monitoring device 70 is arranged at a fixed position on one side of the ground drag chain 30 , and is used to output a position signal each time a vehicle 40 passes by. The trolley subsystem includes a control platform, a plurality of liftable trolleys 10 connected to the control platform, and a traveling aux...

The invention discloses a high-precision frame traveling system and method cooperating with a wheel assembly robot, and relates to the technical field of conveyor control, which includes a ground drag chain trolley subsystem, a monitoring device, and a trolley subsystem. Every time a position signal is output, each time a position signal is received, a liftable trolley will touch the pin of the corresponding trolley, and the control platform will control the ejector pins of all the liftable trolleys to pull out the pins of the corresponding trolley. All trolleys are separated from the power of the ground tow chain, and the traveling auxiliary trolley drives the frame to travel. In the present invention, when the vehicle frame travels to the tire assembly area, the trolley carrying the vehicle frame can be separated from the power of the ground drag chain, and after detachment, an external power source is introduced to drive the trolley to continue forward at a precise speed, so that the wheel assembly robot can Perform precise positioning and assembly to improve the efficiency of automatic assembly of wheels.
