Body-in-white workshop line fast-travel mechanism and its interaction method

Abstract

The invention discloses a rapid passing mechanism for a body-in-white workshop line body. The rapid passing mechanism for the body-in-white workshop line body is a passage arranged between two stations in the line body and allowing staffs to pass transversely, and comprises two safety doors arranged at the two ends of the passage respectively and capable of sealing the passage and two door boxes electrically connected to two door locks respectively; each safety door is provided with one door lock; unlocking buttons for controlling the door locks to be unlocked are arranged on the door boxes; the door boxes are connected to and interact with control terminals of the line body through logic circuits; each control terminal is provided with a human-computer interface; and PLC programs are arranged in the control terminals. The invention further discloses an interactive method for the passing mechanism. According to the rapid passing mechanism for the body-in-white workshop line body and the interactive method for the passing mechanism, through the passing mechanism, a maintenance responder can directly pass through the passage without bypassing the whole line body to reach the other side from one side of the line body; and switches of the safety doors and the state of car entering and exiting of the line body are correlated through the PLC programs of the control terminals, and safety accidents caused by the fact that the staffs enter the passage when a vehicle enters and leaves the passage can be avoided.

Description

technical field [0001] The invention belongs to the technical field of automobile production equipment, and in particular relates to a fast-moving mechanism for a body-in-white workshop line body and an interaction method thereof. Background technique [0002] Body in White (BW) refers to the body that has been welded but not painted, excluding moving parts such as four doors and two covers. It is the carrier of the entire auto parts and is mainly supported by "steel structures". The manufacturing cost of body-in-white accounts for about 40% of the total cost of a car, which shows its position in the auto industry. In order to improve welding production efficiency and reduce production costs to meet the requirements of large-scale production, most of the modern body-in-white welding adopts flow-through welding production lines. The advanced level of welding production lines directly determines the quality and efficiency of body-in-white welding production. The body-in-white...

Problems solved by technology

The body-in-white workshop line is relatively long, generally more than 100 meters, as shown in Figure 1A and Figure 1B Shown is a body-in-white welding line body 1, which is divided into a plurality of continuous stations, and each station performs different processing operations on the body-in-white 2, and in order to prevent production line operators from entering into the line body by mistake during production. Cause safety problems, the line body is continuous, there is no horizontal channel in the middle, when the equipment fails, the maintenance response personnel need to detour from one side of the line body to the other side, and the response efficiency is greatly reduced, especially when the fault occurs on the line body In the middle section, maintenance response personnel need to walk a long distance at one end, which is extremely inconvenient in actual production and seriously affects the production output of body-in-white
