Description
TECHNICAL FIELD
[0001] The utility model relates to the technical field of laser welding, especially relates to a laser circuit structure. BACKGROUND
[0002] Laser welding is a method that uses focused laser beam as energy to bombard the heat generated by welding parts. Because laser has refraction, focusing and other optical properties, laser welding is very suitable for welding of micro parts and poorly accessible parts.
[0003] The laser circuit box is a device capable of emitting laser beams to the welding parts. In order to record and observe the process of laser welding, a camera is arranged in the laser circuit box, which can record the welding process of the welding parts.
[0004] However, during the laser welding process of the welding parts, the laser displayed during welding on the welding parts will cause the video recorded by the camera to have dazzling laser, so that the welding process of the welding parts cannot be clearly seen on the video. UTILITY MODEL CONTENT
[0005] The utility model aims at solving one of the technical problems existing in the prior art. To this end, the utility model provides a laser circuit structure, which can filter laser on the camera shooting recording path, so that the recorded video has no laser display, and the welding process of the welding parts can be clearly seen.
[0006] According to the laser circuit structure of the utility model embodiment, which comprises:
[0007] The box body is defined with a first direction and a second direction perpendicular to each other, the box wall of the box body along the second direction has a laser output port, and the laser output port faces the welding parts;
[0008] The camera is located on the side of the laser output port away from the welding parts along the second direction, and is used for shooting and recording the welding process of the welding parts;
[0009] The laser generating device is located in the box body and is used for emitting laser beams;
[0010] The first beam splitter is located between the camera and the laser output port, and is used for reflecting the laser beams emitted by the laser generating device to the laser output port and allowing the dynamic image of the welding process to penetrate to the camera lens;
[0011] The optical filter is located between the camera and the first beam splitter, and is used for filtering the laser presented by the welding parts.
[0012] According to the laser circuit structure of the utility model embodiment, at least the following beneficial effects are obtained:
[0013] 1. This utility model provides a housing that defines a first direction and a second direction that are perpendicular to each other. The housing wall along the second direction has a laser output port that faces the weldment. This allows the housing to protect the laser circuit structure and prevent it from being affected or damaged by the external environment.
[0014] 2. This utility model incorporates a camera located on the side of the laser output port facing away from the workpiece in the second direction. The camera is used to capture and record the welding process of the workpiece, thereby facilitating the recording of the welding process and, consequently, the analysis of the causes of welding defects.
[0015] 3. This utility model provides a laser generating device inside the housing, which emits a laser beam, thereby facilitating laser welding of the workpiece by outputting the laser beam from the laser circuit structure.
[0016] 4. This utility model incorporates a first beam splitter located between the camera and the laser output port. The first beam splitter reflects the laser beam emitted by the laser generator to the laser output port and allows the dynamic image of the welding process to pass through the camera lens. This facilitates the guidance of the laser beam, enabling it to output from the laser output port. Simultaneously, by refraction and guiding the laser beam, the positions of the laser generator and the camera can be mutually avoided, preventing interference between the laser generator, the camera, and the weldment from being on the same straight line.
[0017] 5. This utility model sets a filter between the camera and the first beam splitter. The filter is used to filter the laser emitted during the welding of the workpiece, so that there is no laser display in the video after the camera captures the image. On the one hand, it can prevent the laser from harming people's eyes. On the other hand, it can make the entire welding process of the product clear in the video, which is conducive to the analysis of the causes of welding defects.
