Description

Technical Field

[0001] The invention relates to the technical field of welding robots, in particular to a high-precision laser welding robot with a self-warning function. Background Art

[0002] Welding robots can automatically weld products. When welding plates, if an object accidentally collides with the welding gun, it is easy to cause damage to the welding gun and the plate. Some welding robots do not have a structure to warn of approaching objects and cannot respond effectively to approaching objects to avoid damage to the welding gun and the plate caused by collision.

[0003] The defects of existing welding robots are: 1. The prior art KR1020150086064A discloses a welding robot, which does not have the function of monitoring whether there are objects approaching the surroundings. When the welding robot is welding a plate, if an object approaches and collides with the welding gun, it is easy to cause damage to the welding gun and the plate. Therefore, a high-precision laser welding robot with a self-warning function that can monitor whether there are objects approaching the surroundings is needed to solve this problem.

[0004] 2. The prior art KR1020130026653A discloses a welding robot. This technology does not have a structure for shielding nearby objects. When an object collides with the welding gun, it is easy to affect the normal welding of the welding gun on the plate and the welding efficiency. Therefore, a high-precision laser welding robot with a self-warning function is needed to shield nearby objects to avoid affecting the welding process to solve this problem.

[0005] 3. The prior art KR1020120060659A discloses a welding robot, which does not have a structure for shielding approaching objects. When a downward-moving baffle mechanism is set to shield approaching objects, the lower baffle is easy to collide with the high-height products below, thereby causing the baffle and the product to be squeezed, and then causing damage to the product and the baffle. Therefore, a high-precision laser welding robot with a self-warning function is needed to solve this problem. It can shield approaching objects by moving downward and avoid squeezing and injury between the downward-moving baffle and the high-height objects below.

[0006] 4. The prior art CN104842103B discloses a welding robot, which does not have a structure for pushing away approaching objects. When objects approach the welding robot, it is easy to affect the observation of the welding process by personnel, and also affects the handling of the plates. Therefore, a high-precision laser welding robot with a self-warning function that can shield and push away approaching objects is needed to solve this problem. Summary of the invention

The high-precision laser welding robot with self-alarm function according to claim 1, characterized in that: A second rod body (31) is symmetrically mounted on the top of the bottom plate (1), and a plurality of rotating rods (32) are movably mounted through the inner side of the second rod body (31).

9. A method for using a high-precision laser welding robot with a self-alert function according to any one of claims 1 to 8, characterized in that: The method of using the high-precision laser welding robot with self-alert function is as follows: S1, placing the spliced ​​plates to be welded on the rotating rod (32), then pressing the plates downward with the pressing plate (29) to fix them, and then welding the plates with the welding gun (14); S2, when the radar (16) detects that an object is moving close to a set distance, the alarm (35) sounds an alarm, and at the same time the lifting plate (18) moves downward so that the movable baffle plate 1 (19) and the movable baffle plate 2 (25) block the moving object; S3. When there is an object under the movable baffle plate 1 (19) or the movable baffle plate 2 (25), the object lifts the movable baffle plate 1 (19) or the movable baffle plate 2 (25) to prevent the movable baffle plate 1 (19) or the movable baffle plate 2 (25) from being damaged due to excessive squeezing force between the movable baffle plate 1 (19) and the movable baffle plate 2 (25) and the object below, and also to prevent the object below from being damaged; S4, then the movable baffle plate 2 (25) moves outward to push away the approaching object.

10. The method for using a high-precision laser welding robot with a self-alert function according to claim 9, characterized in that: The S1 also includes the following steps: S11, using the laser rangefinder component 1 (33) to measure the distance between itself and the inner wall of one side of the frame component 1 (6), and using the laser rangefinder component 2 (34) to measure the distance between itself and the inner wall of the front side of the frame component 2 (10), so as to facilitate the controller component (3) to determine the position of the welding gun (14).
