[0009] By adopting the above technical solution, the workpiece is placed on the welding table to facilitate welding by the laser welding head. After welding, the electric push rod is activated to move the cleaning brush, which cleans the welding table and sweeps the debris to the collection port. This facilitates the collection of debris into the collection box. When the collection box has collected a lot of debris, the clamping plate is rotated to move it away from the fixed clamping part. At this time, the cover plate can be stretched to move the positioning slider, causing the positioning slider to disengage from the positioning groove. Then, the cover plate can be rotated to move it away from the discharge port, thereby cleaning the debris in the collection box. This avoids the need for frequent disassembly of the collection box, making it easier to clean the collected debris and improving work efficiency.

[0015] By adopting the above technical solution, when the cleaning brush cleans the debris, the first short plate, the long plate and the second short plate are rotated so that the first short plate and the second short plate are supported on both sides of the welding table, and the long plate covers the top of the welding table, thereby preventing the debris from flying.

[0016] Optionally, the connecting rod is rotatably connected to the support platform, and a protective cover is fitted on the laser welding head. Two limiting rods that are slidably connected to the top of the protective cover are fixedly connected to the top of the mounting plate.

[0017] By adopting the above technical solution, the protective cover is used to protect the workpiece when the laser welding head is welding the workpiece, so as to avoid the flying debris and injury to personnel.

[0018] Optionally, the mounting plate has a positioning slot at its bottom end, and a fixing cylinder is fixedly connected to the top end of the support platform. A positioning rod that mates with the positioning slot is slidably connected inside the fixing cylinder, and a spring is provided between the positioning rod and the fixing cylinder.

[0019] By adopting the above technical solution, the spring pushes the positioning rod to move, and one end of the positioning rod is inserted into the positioning slot to position the mounting plate, thereby keeping the laser welding head aligned with the welding table and improving the welding accuracy of the workpiece.

[0020] Optionally, two U-shaped frames are fixedly connected to the top of the support platform. The two U-shaped frames are located on both sides of the welding platform. Fixed rods are fixedly connected inside the two U-shaped frames. Limiting sliders are fixedly connected to both ends of the cleaning brush. The two limiting sliders are slidably connected to the two fixed rods respectively.

[0021] By adopting the above technical solution, the limiting slider and the fixed rod cooperate to limit the cleaning brush, thereby preventing the cleaning brush from deviating and thus improving the stability of the equipment.

[0023] In summary, this utility model has at least one of the following beneficial technical effects:

[0024] This dust removal device for laser welding places the workpiece on the welding table to facilitate welding by the laser welding head. After welding, an electric push rod is activated to move the cleaning brush, which cleans the welding table and sweeps the debris to the collection port. When the collection box has accumulated a lot of debris, the clamping plate is rotated to move away from the fixed clamp. At this time, the cover plate can be stretched to move the positioning slider, causing the positioning slider to disengage from the positioning groove. The cover plate can then be rotated to move away from the discharge port, thus cleaning the debris in the collection box. This avoids the need for frequent disassembly of the collection box, making it easier to clean the collected debris and improving work efficiency. Attached Figure Description

One end of the collection box 2 is fixedly connected to a fixing clip 13. A clamping plate 14 that cooperates with the fixing clip 13 is rotatably connected to the cover plate 10. The workpiece is placed on the welding table 3 to facilitate welding of the workpiece by the laser welding head 6. After welding, the electric push rod 7 is activated to drive the cleaning brush 8 to move, so that the cleaning brush 8 cleans the welding table 3, thereby sweeping the debris on the welding table 3 to the collection port, so that the debris can be swept into the collection box 2. When the collection box 2 has collected a lot of debris, the clamping plate 14 is rotated so that the clamping plate 14 is away from the fixing clip 13. At this time, the cover plate 10 can be stretched to drive the positioning slider 12 to move, so that the positioning slider 12 is disengaged from the positioning groove 11. At this time, the cover plate 10 can be rotated so that the cover plate 10 is away from the discharge port, thereby cleaning the debris in the collection box 2. This avoids the need to frequently disassemble the collection box 2, making it easier to clean the collected debris and improving work efficiency.

[0035] Reference Figure 2 and Figure 3 The collection box 2 is equipped with a transparent observation window 15, which is used to facilitate personnel to observe the debris in the collection box 2 and to facilitate timely discharge of the debris.

[0036] Reference Figure 4 and Figure 5 The lower inner side wall of the collection box 2 is provided with an inclined guide 16 that cooperates with the discharge port. When discharging debris, the inclined guide 16 is used to guide the debris to the position of the discharge port, thereby improving the discharge efficiency.

[0037] Reference Figure 1 and Figure 2One end of the support platform 1 is rotatably connected to a first short plate 17 near the top. One end of the first short plate 17 is rotatably connected to a long plate 18. One end of the long plate 18 is rotatably connected to a second short plate 19. When the cleaning brush 8 cleans the debris, the first short plate 17, the long plate 18 and the second short plate 19 are rotated so that the first short plate 17 and the second short plate 19 are respectively supported on both sides of the welding platform 3, and the long plate 18 covers the top of the welding platform 3, thereby preventing the debris from flying.

A positioning rod 23 that cooperates with the positioning slot is slidably connected inside the fixing cylinder 22. A spring 24 is provided between the positioning rod 23 and the fixing cylinder 22. The spring 24 pushes the positioning rod 23 to move, and one end of the positioning rod 23 is inserted into the positioning slot to position the mounting plate 5, thereby keeping the laser welding head 6 aligned with the welding table 3 and improving the welding accuracy of the workpiece.

Fixed rods 26 are fixedly connected inside the two U-shaped frames 25. Limiting sliders 27 are fixedly connected to both ends of the cleaning brush 8. The two limiting sliders 27 are slidably connected to the two fixed rods 26 respectively. The limiting sliders 27 cooperate with the fixed rods 26 to limit the cleaning brush 8, thereby preventing the cleaning brush 8 from tilting and thus improving the stability of the equipment.

[0041] In summary, the working principle and process of this dust removal device for laser welding are as follows: First, the workpiece is placed on the welding table 3 to facilitate welding by the laser welding head 6. After welding, the electric push rod 7 is activated to move the cleaning brush 8, which cleans the welding table 3, sweeping debris from the welding table 3 to the collection port. This facilitates the collection of debris into the collection box 2. When the collection box 2 has accumulated a large amount of debris, the clamping plate 14 is rotated away from the fixing clamp 13. At this time, the cover plate 10 can be stretched to move the positioning slider 12, disengaging it from the positioning groove 11. The cover plate 10 can then be rotated away from the discharge port to clean the debris in the collection box 2. This avoids the need for frequent disassembly of the collection box 2, facilitating the cleaning of collected debris and improving work efficiency. The transparent observation window 15 allows personnel to easily observe the debris in the collection box 2 for timely monitoring. The debris is discharged by an inclined guide 16, which guides the debris to the discharge port to improve discharge efficiency. When the cleaning brush 8 cleans the debris, the first short plate 17, the long plate 18, and the second short plate 19 are rotated, so that the first short plate 17 and the second short plate 19 are supported on both sides of the welding table 3, and the long plate 18 covers the top of the welding table 3 to prevent debris from flying. The protective cover 20 is used to protect the workpiece when the laser welding head 6 is welding it, to prevent debris from flying and causing injury. The spring 24 pushes the positioning rod 23 to move, and one end of the positioning rod 23 is inserted into the positioning slot to position the mounting plate 5, so that the laser welding head 6 is aligned with the welding table 3, thereby improving the welding accuracy of the workpiece. The limiting slider 27 cooperates with the fixing rod 26 to limit the cleaning brush 8, thereby preventing the cleaning brush 8 from tilting and improving the stability of the equipment.
