Description

Technical Field

[0001] The present invention relates to the technical field of laser welding equipment, and in particular to a high-efficiency laser welding equipment and a use method thereof. Background Art

[0002] Door and window processing and welding equipment is one of the types of door and window equipment. It is the equipment that door and window companies need to use when producing doors and windows. Due to the different materials of doors and windows, the types of doors and windows are also different. The common doors and windows on the market are generally: wooden windows, steel windows, plastic steel windows, broken bridge aluminum doors and windows, high-end wood-clad aluminum doors and windows, etc. Regardless of the type of doors and windows, the processing equipment for doors and windows is generally divided into: cutting equipment, welding machine (corner assembly) equipment, corner cleaning equipment, milling equipment, stamping equipment, assembly equipment, etc. The existing door and window processing uses welding guns for welding.

[0003] Referring to the Chinese invention patent, the publication number is: CN115971658A, and the name is: A laser welding device. This invention patent can fix the aluminum alloy doors and windows when they are assembled at the corners and weld and fix the inner walls of the fixed aluminum alloy doors and windows, thereby achieving the purpose of assembling the corners of the aluminum alloy doors and windows; it overcomes the problem of obvious extrusion marks caused by the corner assembly method using the collision angle assembly method.

[0004] However, in actual use, the above technical solutions and related prior arts still have some problems:

[0005] 1. In the current welding process, after the welding operation is completed, the window strips need to be manually placed in the predetermined position and fixed by the corner clamp device. When welding to the third window strip, the four window strips are heavy to flip together. Manual flipping and switching of welding angles is time-consuming and laborious. If you are not careful, the welded corners may break, affecting product quality and reducing the automation and operation efficiency of the entire production line.

[0006] 2. During the welding process, after each welding operation of a window strip corner is completed, the process needs to be interrupted to manually remove the welded part, reposition the next window strip to be welded, and then perform subsequent welding operations. This single-shot, one-by-one welding method seriously restricts the improvement of production efficiency;

[0007] 3. Faced with the diverse requirements for window strip specifications, the current welding preparation stage requires operators to adjust the relative spacing between the corner clamp devices one by one according to the size differences of the window strips to ensure that the window strips can be clamped correctly and firmly. The manual adjustment process is cumbersome, which reduces the flexibility and adaptability of the operation process. Summary of the invention

[0026] 1. This high-efficiency laser welding equipment facilitates the window strip to be close to the conveyor belt through the fourth electric push rod.

At the same time, the window strip can be located in the middle position. When the vertical plate moves, the side panels are driven to slide, thereby facilitating the adaptation to window strips of different specifications and increasing practicality.

[0027] 2. For this high-efficiency laser welding equipment, when the bearing strip on the conveyor belt enters the protective shell, the size of the card slot between the card block and the bearing strip is convenient for the card connection of the window strip, and the slide bar is disengaged from the guide slot, which is convenient for fixing the window strip. When the conveyor belt is working, it drives the four window strips to rotate toward the inside of the machine body at the same time and splice them, forming a multi-layer spliced ​​window strip on the inside of the machine body, so as to facilitate welding layer by layer. When facing window strips of different specifications, the first electric push rod pushes the two pairs of moving blocks to move toward or away from each other, thereby driving the conveyor belt to move and the window strip to move, so as to facilitate the adjustment of the spacing between the adjacent window strips on both sides, and facilitate the splicing of window strips of different specifications. The welded window strip moves to the top of the conveyor belt, the control rod contacts the protrusion, and the card block extends outward, so as to facilitate the release of the welded window strip, so as to facilitate the removal of the welded window strip.

[0028] 3.

The dual laser heads work in a mirrored manner along the end block, thereby welding the window strips on both sides of the end block at the same time. Two spliced ​​window strips can be welded at one time, and the conveyor belt drives one unit of the window strip to move each time, which facilitates the welding of the unwelded bottom surface and the top surface of the next window strip, thereby improving work efficiency.

[0056] Embodiment 3: On the basis of Embodiment 2, with reference to Figure 4 , Figure 6 and Figure 7 , a feeding mechanism 4 is connected to the body 1. The feeding mechanism 4 includes a blanking plate 41. The body 1 is slidably connected with a blanking plate 41 on the outside of each moving block 23. The blanking plate 41 is fixedly connected to the moving block 23. Vertical plates 49 are slidably connected to the four corners of the body 1. A second telescopic rod 46 is installed between each moving block 23 and the vertical plates 49 on both sides. Side plates 45 are provided on both sides of the blanking plate 41. The side plates 45 are fixed to the vertical plates 49. The blanking plate 41 is used to place the window strips 5. A pushing assembly for pushing the window strips 5 to move is connected to the blanking plate 41, so as to facilitate the placement of new window strips 5 and adapt to different specifications of window strips 5.

[0057] In the present invention, the pushing assembly includes a fourth electric push rod 44. The fourth electric push rod 44 is fixedly connected to the surface of the blanking plate 41. The telescopic end of the fourth electric push rod 44 is fixedly connected to a pushing bar 7. A back plate 42 is fixedly connected to the protective shell 21. A "C"-shaped intercepting plate 43 is fixedly connected to the blanking plate 41. The window strip 5 is placed between the back plate 42 and the intercepting plate 43, so as to facilitate pushing the window strip 5 close to the conveyor belt 22. At the same time, with the cooperation of the back plate 42 and the intercepting plate 43, it is convenient to add multiple window strips 5 at one time, reducing the workload.

[0058] In the present invention, a pair of support rods 48 are rotatably connected to one end of the blanking plate 41 close to the conveyor belt 22. The support rods 48 are used to support the window strips 5. An "I"-shaped抵触杆47 is slidably connected to the bottom end of the blanking plate 41.

[0059] In the present invention, a balancing mechanism 6 is connected to the back panel 42, and the balancing mechanism 6 includes a third rack 61. A pair of third racks 61 are slidably connected inside the back panel 42. The back panel 42 is located between the pair of third racks 61 and is rotatably connected with a third gear 62. The third gear 62 is meshed with the third rack 61. The ends of the pair of third racks 61 on the back panel 42 are respectively fixed to the side panels 45 on both sides, so that the conveyor belt 22 is always kept in the center, which is convenient for clamping the middle of the window strip 5 and ensuring the quality of splicing.

[0060] Working principle: four window strips 5 are placed between the back plates 42 and the intercepting plates 43 on the four unloading plates 41 respectively, and the fourth electric push rod 44 is started. The fourth electric push rod 44 extends, thereby pushing the window strip 5 through the pushing strip 7, so that the window strip 5 is close to the conveyor belt 22. At the same time, the pushing strip 7 pushes the contact rod 47, and the contact rod 47 pushes the support rod 48 to rotate out in the direction of the conveyor belt 22. The upper surface of the support rod 48 is parallel to the surface of the unloading plate 41. When the window strip 5 is close to the conveyor belt 22, it is supported by the support rod 48. When pushing the window strip 5, the side plates 45 on both sides of the unloading plate 41 contact with the two ends of the window strip 5, thereby ensuring the stable sliding of the window strip 5 and enabling the window strip 5 to be located in the middle position. When the vertical plate 49 moves, the side plates 45 are driven to slide, so as to adapt to window strips 5 of different specifications and increase practicality.

[0061] The added window strip 5 is close to the conveyor belt 22, and the first telescopic rod 271 is used to support the protective shell 21 and the conveyor belt 22. When the conveyor belt 22 is started and the bearing strip 24 on the conveyor belt 22 enters the protective shell 21, the slide bar 254 on the bearing strip 24 enters the guide groove 256. The slide bar 254 slides outward through the push of the guide groove 256, pulling the block 251 to slide outward, and the first spring 252 is elongated to increase the size of the slot between the block 251 and the bearing strip 24. The block 251 moves downward with the bearing strip 24, thereby engaging the window strip 5. The window strip 5 enters between the block 251 and the bearing strip 24. When the window strip 5 is completely When entering, the slide bar 254 is disengaged from the guide groove 256, and the first spring 252 contracts, thereby pulling the block 251 to contact the window strip 5. The side of the block 251 that contacts the window strip 5 is in an inclined shape, which is convenient for pressing the window strip 5. At this time, the fourth electric push rod 44 is retracted, the contact rod 47 is disengaged from the support rod 48, and the support rod 48 rotates downward under its own gravity, so as to facilitate the transportation of the window strip 5 through the conveyor belt 22. When the conveyor belt 22 is working, it drives the four window strips 5 to rotate toward the inside of the machine body 1 at the same time and splice them, forming a multi-layer spliced ​​window strip 5 on the inside of the machine body 1, so as to facilitate welding layer by layer. At 5, the two pairs of first electric push rods 263 are started to control the sliding of the two pairs of first racks 261. Under the action of the first gear 262, each pair of moving blocks 23 moves toward or away from each other, thereby driving the conveyor belt 22 to move, and driving the window strips 5 to move, so as to facilitate the adjustment of the spacing between the adjacent window strips 5 on both sides, and facilitate the splicing of window strips 5 of different specifications. The second telescopic rod 46 facilitates the movement of the vertical plate 49, thereby facilitating the operation of the side plate 45 and the telescopic curtain 272. The telescopic curtain 272 can be extended or shortened to play a protective role, avoiding the splashing of sparks and the dazzling strong light during welding. The vertical plate 49 drives the side plate When the third rack 61 moves, the third gear 62 is located in the middle of the two side plates 45. Under the action of the third gear 62, the position of the conveyor belt 22 can be kept centered and immovable, so as to ensure that the middle position of the window strip 5 is clamped and its stability is ensured. The welded window strip 5 moves to the top of the conveyor belt 22, and the control rod 253 contacts the protrusion 255. The protrusion 255 is arc-shaped, pushing the control rod 253 to move outward. The control rod 253 pushes the sliding rod 254 to slide, and the clamping block 251 extends outward, so as to facilitate the release of the welded window strip 5, so as to facilitate the removal of the welded window strip 5.

[0062] During welding, the robot arm 31 drives the end block 32 to move so that the end block 32 is located between the two middle layers of spliced ​​window strips 5, and the end block 32 is located in the middle of the two layers of window strips 5. The robot arm 31 drives the end block 32 to move, and the laser head 33 welds the splicing gap of the window strip 5. The third electric push rod 38 controls the sliding of the second rack 37, thereby driving the two second gears 36 to rotate, driving the two laser heads 33 to deflect, and the second electric push rod 34 is used to control the extension and contraction of the laser head 33, so as to facilitate welding of the side splicing gap of the window strip 5. The dual laser heads 33 work in a mirrored manner along the end block 32, so as to weld the window strips 5 on both sides of the end block 32 at the same time, and two spliced ​​window strips 5 can be welded at one time. Each time, a unit of window strip 5 is driven to move by the conveyor belt 22, so as to facilitate welding of the unwelded bottom surface and the top surface of the next window strip 5, thereby improving work efficiency.

[0063] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
