Description

Intelligent Control Method of Welding Robot

technical field

The invention relates to the field of robot welding, in particular to an intelligent control method for a welding robot.

Background technique

In the current welding production of automobiles and parts, a large number of robots are used for welding, and robot welding is mainly used in spot welding and arc welding. When using a robot for welding, first use tooling to position the auto parts together, and then the welding robot performs welding according to the position of the welding spot. Usually, a welding robot needs to work on several stations. This is because models often share a production line or weld in different procedures. These stations and this welding robot form a welding system.

In the actual welding process, the welding spots of some auto parts are not easy to be welded. At this time, it is necessary to rotate the welding tool through the turntable so that the welding robot can weld to the welding spots. The specific flow of the welding process is as follows: When a certain station puts the parts and requests welding, the welding robot goes to work, when the welding robot reaches the welding point that cannot be welded, it requests the rotation angle of the turntable, and the welding robot waits here, when the turntable rotates After it is in place, an instruction to continue is issued, and the welding robot continues welding to the end. After the welding robot completes the current station, it continues to weld other stations. There is a problem with this welding method, that is, when the turntable is rotating, the welding robot is in a waiting state. Generally, it takes about 8 seconds for the turntable to rotate. During this time, the welding robot is in a static state, without any action, and does not generate any value. , and the welding time is wasted, and the production efficiency is low.

Chinese invention patent 201410314887.1 discloses a robot welding system with continuous stations, which uses robots and three workbenches to save time. However, this welding system has the following disadvantages: firstly, the workbench can only place the welding spots that the welding robot can weld, and secondly, it is necessary to complete the welding of the current workbench before going to the next scheduled workbench, which cannot solve the problem of the welding robot when the turntable is rotating. Waiting, wasting welding time and productivity.

Contents of the invention

Aiming at the deficiencies of the above-mentioned prior art, the object of the present invention is to provide an intelligent control method for a welding robot that can effectively improve production efficiency.

In order to solve the problems of the technologies described above, the present invention adopts the following technical solutions:

An intelligent control method for a welding robot. The workstation where the welding robot is located has multiple welding stations. The welding robot performs welding operations at station A in the workstation. During the rotation of the turntable, if there is a station B in the workstation that needs to perform welding operations, the welding robot first moves to the station B to perform welding operations, and after the turntable is rotated in place, the welding robot returns to the station A. The station continues the welding operation of the station.

Preferably, when the welding robot performs the welding operation at station B and returns to station A, it is necessary to record the welding interruption position of station B. After the welding operation at station A is completed, the welding robot should return to station B to stop welding. position to continue welding operations.

The above-mentioned technical solution has the following beneficial effects: with the intelligent control method of the welding robot, when the turntable of the current working station of the welding robot needs to be rotated, the welding robot can first move to other stations for welding operations, so that the welding of the welding robot can Time is fully utilized, which can effectively improve production efficiency.

Description of drawings

Fig. 1 is a schematic flow chart of an embodiment of the present invention.

Detailed ways

Preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

As shown in Figure 1, the workstation where the welding robot is located has multiple welding stations, and the welding robot can perform welding operations at each station. When using the welding robot intelligent control method for welding operations, first place the parts to be welded on the tooling of station A for positioning, and then station A sends a request for welding instructions to the welding robot, and the welding robot moves to station A for processing Welding operation, during the welding operation, if all welding spots can be welded at station A without rotating the turntable, the welding robot will continue to weld at station A until the end.

For example, some solder joints at station A need to be rotated at a certain angle before welding, then the welding robot first stops welding and makes the turntable rotate. During the rotation of the turntable at station A, if there is no other station at the workstation where the welding robot is located to issue a welding operation instruction, the welding robot will stop working and wait for the turntable at station A to rotate in place before continuing to work at station A. Carry out the welding operation until the end. During the rotation of the A-station turntable, if there is a B-station in the workstation that needs to perform welding operations, the welding robot will first move to the B-station for welding operations. After the turntable is rotated in place, the welding robot will return to the A-station. Continue to carry out the welding operation of this station until the end. When the welding robot performs welding at station B and returns to station A, it is necessary to record the welding interruption position of station B. After the welding operation at station A is completed, the welding robot should return to station B to continue welding from the interrupted position . The above-mentioned A station and B station are only for distinguishing the stations, which have no practical significance, and should not be understood as limitations on the technical solution of the present invention.

With the intelligent control method of the welding robot, when the turntable of the current working station of the welding robot needs to be rotated, the welding robot can first move to other stations for welding operations, so that the welding time of the welding robot can be fully utilized, which can effectively Increase productivity.

The above is a detailed introduction to a welding robot intelligent control method provided by the embodiment of the present invention. For those of ordinary skill in the art, according to the idea of the embodiment of the present invention, there will be changes in the specific implementation and application range. In summary, the content of this specification should not be construed as limiting the present invention, and any changes made according to the design concept of the present invention are within the scope of protection of the present invention.
