Description

Technical Field

[0001] The utility model relates to the technical field of welding robots, in particular to a welding robot with a shielding mechanism. Background Technique

[0002] A welding robot is an industrial robot engaged in welding (including cutting and spraying). According to the definition of an industrial robot belonging to a standard welding robot by the International Organization for Standardization (ISO), an industrial robot is a multi-purpose, reprogrammable automatic control manipulator with three or more programmable axes and is used in the field of industrial automation. To adapt to different uses, the mechanical interface of the last axis of the robot is usually a connecting flange to which different tools or end effectors can be attached. A welding robot is one that has a welding torch or a welding (cutting) gun attached to the flange of the last axis of the industrial robot so that it can perform welding, cutting or thermal spraying.

[0003] During the use of the existing welding robot, the position of the laser welding head can be adjusted arbitrarily through the robotic arm, and then the laser welding head is used to perform laser welding on the sheet metal. During the above welding process, strong light will be generated. The strong light not only easily causes light pollution, but also easily causes discomfort to the eyes of the workers in the workshop, resulting in poor use effect. Therefore, there is an urgent need for a welding robot with a shielding mechanism to solve the above problems. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a welding robot with a shielding mechanism.

[0005] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0006] A welding robot with a shielding mechanism includes a robotic arm. An installation plate is fixed on the output end of the robotic arm. A laser welder is fixed in the middle of one side wall of the installation plate. A telescopic protective cover is arranged outside the laser welder. A lifting cavity is formed in the fixed part of the protective cover. Four groups of telescopic columns are circumferentially distributed in the lifting cavity. A spring is sleeved outside the telescopic column. An electromagnet is arranged on one side of the telescopic column. A magnetic block is fixed at a position corresponding to the electromagnet at the top of the movable arm of the protective cover.

[0007] Preferably, the installation plate is fixed to the output end of the robotic arm by bolts, and the laser welder is fixed to one side wall of the installation plate by bolts.

[0008] Preferably, the fixed part of the protective cover is connected to the installation plate by screws. The lifting cavity is formed in the fixed part of the protective cover. The inner lining of the protective cover is made of a flame-retardant and heat-resistant material.

[0009] Preferably, the fixed arm of the telescopic column is fixed in the lifting cavity, the spring is welded on the outer side wall of the telescopic column, and the movable end of the telescopic column is fixedly connected to the movable end of the protective cover.

[0010] Preferably, the electromagnet is fixed in the lifting cavity by screws, the magnetic block is fixed on the movable arm of the protective cover by screws, and both the electromagnet and the magnetic block are arc-shaped structures.

[0011] Preferably, multiple groups of ball bearings are circumferentially distributed on the bottom wall of the movable part of the protective cover.

[0012] Preferably, a mounting seat is welded to the bottom end of the robotic arm.

[0013] The beneficial technical effects of the present utility model are as follows:

[0014] The present utility model designs a shielding mechanism composed of a protective cover, a telescopic column, a spring, an electromagnet, and a magnetic block. During the welding process, the protective cover can hide the laser cutter, thereby blocking the strong optical fiber generated during the welding process, avoiding light pollution and discomfort to the eyes of the staff. At the same time, the combination of the telescopic column and the spring enables the protective cover to have a certain lifting buffering performance, ensuring the welding effect. When idle, the electromagnet can be energized to adsorb the magnetic block, making the protective cover in a compressed state, and the laser cutter can be exposed for easy maintenance and repair, with good use effects.
