Description

Technical Field

[0001] The utility model relates to welding equipment, in particular to laser galvanometer scanning welding equipment. Background Art

[0002] Galvanometer-scanning laser welding technology is a new technology that has only emerged internationally in recent years and has rapidly become a research hotspot worldwide. It involves scanning the desired weld pattern through the deflection of a galvanometer, and then welding along the scanned trajectory. The galvanometer can achieve rapid adjustment and high-frequency scanning, allowing the laser beam to be precisely focused on the weld area. By finely adjusting the focal length and scanning speed, galvanometer-type laser welding machines can achieve high-speed and precise welding. This welding technology greatly shortens processing time and improves processing efficiency.

[0003] Among them, welding is achieved by heating the metal, applying pressure to melt the metal, and then solidifying it by cooling. During the welding process, workers usually use welding wire or welding rod as filler material. These filler materials contain some metal alloys and flux. When the filler material is heated and melted, a layer of copper shavings-like substance, namely welding slag, will form on its surface. With welding slag, welding slag splashing is inevitable. The melted metal particles or slag will fly around, which will affect the surrounding welding environment and safety, and even damage the welding equipment.

[0004] However, the existing galvanometer scanning laser welding equipment cannot effectively handle the splashing of welding slag during welding. Therefore, it is necessary to design a laser galvanometer scanning welding equipment. Utility Model Content

[0005] In order to overcome the shortcoming that the existing galvanometer scanning laser welding equipment cannot effectively handle the welding slag splash during welding, the technical problem is to provide a laser galvanometer scanning welding equipment.

[0006] The technical solution is as follows: A laser galvanometer scanning welding equipment, including a workbench, an electric slide, an electric slide, a laser galvanometer welder, a collecting tube, a guide rod, a first elastic member, a cleaning mechanism and a controller. An electric slide is provided on the top of the workbench, and an electric slide is slidably provided on the electric slide. A laser galvanometer welder is fixedly connected to the bottom of the electric slide. A collecting tube is placed on the top of the workbench, and guide rods are fixedly connected to the front and rear sides of the top of the collecting tube. Both guide rods are slidably connected to the electric slide. A first elastic member is connected between the two guide rods and the electric slide. A cleaning mechanism is provided inside the collecting tube, and a controller is provided on the right front side of the workbench. The controller is electrically connected to the electric slide and the laser galvanometer welder.

[0007] Optionally, the cleaning mechanism includes a fixed rod, a scraper block and a handle. Two fixed rods are fixed on the front and rear sides of the collecting tube. Scraper blocks are slidably connected between the four fixed rods. The scraper blocks fit into the inner wall of the collecting tube. Handles are slidably connected on the left and right sides of the front of the collecting tube. Both handles are fixed to the scraper blocks.

[0008] Optionally, a clamping member and a second elastic member are further included. Clamping members are symmetrically slidably provided on both the front and rear sides of the upper portion of the workbench, and a second elastic member is connected between the four clamping members and the workbench.

[0009] Optionally, a glass plate is further included, and a glass plate is provided on the front side of the collecting cylinder.

[0010] Optionally, foot pads are also included, with two foot pads being provided on the front and rear sides of the bottom of the workbench.

[0011] Optionally, heat dissipation holes are provided on both the left and right sides of the workbench.

[0012] Optionally, the middle portion of the collecting tube is hollowed out, and the collecting tube is located directly below the laser galvanometer welder.

[0021] To make the objectives, technical solutions, and advantages of the present invention more clearly apparent, the present invention will be further described in detail below with reference to the accompanying drawings. It is hereby stated that any directional terms such as "up," "down," "left," "right," "front," "back," "inside," and "outside" that appear or will appear in this document are based solely on the accompanying drawings and are not intended to limit the present invention.

[0022] Example: A laser galvanometer scanning welding device, such as Figure 1-Figure 5 As shown, it includes a workbench 1, an electric slide rail 2, an electric slide seat 3, a laser galvanometer welder 4, a collecting cylinder 5, a guide rod 6, a first elastic member 7, a cleaning mechanism, a glass plate 11, a controller 14 and a foot pad 15. The top of the workbench 1 is fixedly connected to the electric slide rail 2, and the electric slide rail 2 includes a transverse slide rail and a longitudinal slide rail. The longitudinal slide rail is connected to the top of the workbench 1, and a transverse slide rail is installed on the longitudinal slide rail. Heat dissipation holes are provided on both sides of the workbench 1. The transverse slide rail of the electric slide rail 2 is slidably connected to the electric slide seat 3. The transverse slide rail can move back and forth on the longitudinal slide rail. The bottom of the electric slide seat 3 is fixedly connected to the laser galvanometer welder 4 by bolts. Starting the electric slide 3 can drive the laser The laser galvanometer welder 4 moves left and right on the horizontal slide rail. A collecting cylinder 5 is placed on the top of the workbench 1. The middle part of the collecting cylinder 5 is hollow, and the collecting cylinder 5 is located directly below the laser galvanometer welder 4. Guide rods 6 are fixed to the front and back sides of the top of the collecting cylinder 5. The two guide rods 6 are slidably connected to the electric slide 3. A first elastic member 7 is connected between the two guide rods 6 and the electric slide 3. A cleaning mechanism is provided inside the collecting cylinder 5. A glass plate 11 for observing the inside of the collecting cylinder 5 is provided in the middle of the front side of the collecting cylinder 5. A controller 14 is provided on the right side of the front of the workbench 1. The controller 14 is electrically connected to the electric slide 3 and the laser galvanometer welder 4. Two foot pads 15 are provided on the front and back sides of the bottom of the workbench 1.

[0023] like Figure 1 and Figure 3 As shown, the cleaning mechanism includes a fixed rod 8, a scraper block 9 and a handle 10. Two fixed rods 8 are fixedly connected to the front and rear sides of the collecting tube 5. Scraper blocks 9 are slidably connected between the four fixed rods 8. The scraper blocks 9 fit together with the inner wall surface of the collecting tube 5. Vertical slide grooves are provided on the left and right sides of the front of the collecting tube 5. The collecting tube 5 is slidably connected to two handles 10 in the vertical slide grooves on both sides. Both handles 10 are fixed to the scraper blocks 9.

[0024] like Figure 1 、 Figure 2 、 Figure 4 and Figure 5 As shown, it also includes a clamping member 12 and a second elastic member 13. Guide grooves are symmetrically provided on the front and back sides of the upper part of the workbench 1. A clamping member 12 is slidably provided in each guide groove to fix the welding plate in the center. The shape of the clamping member 12 is L-shaped, and a second elastic member 13 is connected between the four clamping members 12 and the workbench 1.

[0025] This equipment can be used when galvanometer scanning laser welding is required. First, place the equipment horizontally, and then the staff will move the collecting tube 5 upward. While moving, the guide rod 6 also moves upward and the first elastic member 7 is compressed. After moving upward to a certain distance, this state is maintained. Then, the staff will place the plate to be welded between the four clamping members 12, and the second elastic member 13 will be compressed accordingly. After the plate is completely placed between the four clamping members 12, the second elastic member 13 will drive the plate to move to the middle of the workbench 1 under the action of reset and fix it in the center. Then the staff can stop moving the collecting tube 5 upward, and then the collecting tube 5 will fall to the top of the plate under the action of the reset of the first elastic member 7 and gravity.

[0026] Next, the staff needs to start the electric slide 3 and the laser galvanometer welder 4 through the controller 14 to work. When the laser galvanometer welder 4 is operating, the staff can observe the welding process inside the collecting tube 5 through the glass plate 11. During welding, some molten metal particles or slag will splash around. Some of these slags will fall on the plate or workbench 1, and some will splash and adhere to the inner wall of the collecting tube 5. The collecting tube 5 effectively limits the splash range of the slag and effectively prevents the impact of the slag splash on the safety of the surrounding environment. When the electric slide 3 drives the laser galvanometer welder When moving on the electric slide rail 2, the collecting cylinder 5 will also move along to isolate the splashing welding slag. This equipment is also suitable for plates of different thicknesses and shapes. Finally, after welding is completed, the collecting cylinder 5 is moved upward and the welded plate is taken out. Then the staff can move the scraper 9 by moving the handle 10 up and down to scrape the welding slag adhered to the inner wall of the collecting cylinder onto the workbench 1, and then clean the welding slag on the workbench 1. At this point, a round of galvanometer scanning laser welding is completed. Repeating the above steps can continuously perform galvanometer scanning laser welding.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
