Description

Technical Field

[0001] The utility model relates to the technical field of laser welding, in particular to a laser welding device. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a laser beam with a high energy density as a heat source. That is, the laser radiation heats the surface of the workpiece, and the surface heat diffuses inward through heat conduction. By controlling parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the workpiece is melted to form a specific molten pool. Due to its unique advantages, it has been successfully applied to the precision welding of micro and small parts. For example, the Chinese patent document with the publication number CN220093458U discloses a galvanometer laser welding device. The galvanometer laser welding device includes a workbench. Two longitudinal guide rails are fixedly installed on the workbench. A transverse guide rail is slidably installed between the two longitudinal guide rails. A vertical guide rail is arranged on one side of the transverse guide rail. The vertical guide rail is slidably connected to the transverse guide rail through a slider. A connecting plate is slidably installed on the vertical guide rail. A welding main body is fixedly installed on one side of the connecting plate. A vertical plate is slidably installed on the connecting plate. A limiting plate is fixedly installed on the vertical plate. A fixing member is arranged between the limiting plates. A spring is arranged between the fixing member and the limiting plate. One end of the spring is fixedly connected to the limiting plate. In this way, it can be avoided that when the welding device is slightly collided, it is extremely easy to drive the workpiece to move along with it, resulting in the deviation of the workpiece, thereby affecting the welding efficiency.

[0003] The existing galvanometer laser welding device has the following deficiencies in actual use: When it is necessary to adjust the position of the welding main body and the workpiece, it is necessary to rotate the screw component to move the vertical plate, and at the same time drive the pressing plate to move along with it, so that the pressing plate can move along with the welding main body. In this way, during the process of the welding main body moving from one welding point to another welding point, the pressing plate cannot press down to fix the workpiece. When the device is slightly collided, it is easy to cause the deviation of the workpiece and affect the welding quality. In view of this, the laser welding device of the present application is proposed. Summary of the Utility Model

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the internal communication of two elements or the interaction relationship between two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0034] As Figures 1 to 2As shown, in one embodiment, a laser welding device 1 includes a frame body 10, a material fixing mechanism 20, and a laser mechanism 30. The material fixing mechanism 20 includes a pallet 21, a right-angle plate 22, a pressing member 23, a telescopic member 24, and two limiting blocks 25. The pallet 21 is slidably disposed on the frame body 10. The right-angle plate 22 is disposed at one of the four corners of the pallet 21. The two limiting blocks 25 are both slidably disposed on the pallet 21. The two limiting blocks 25 are used to push against two adjacent sides of the workpiece, so that the right-angle plate 22 abuts against the other two adjacent sides of the workpiece. The pressing member 23 is rotatably disposed on the right-angle plate 22 and is located above the workpiece. The telescopic member 24 is disposed on the right-angle plate 22. The output end of the telescopic member 24 is connected to the pressing member 23. The telescopic member 24 is used to drive the pressing member 23 to press or release the workpiece. The laser mechanism 30 is disposed on the frame body 10 and is used to weld the workpiece.

[0035] It should be noted that the pallet 21 is longitudinally slidably disposed on the frame body 10. For example, the pallet 21 slides on the frame body 10 through a slide rail. Further, the right-angle plate 22 is an L-shaped mechanism. The right-angle plate 22 is disposed at one of the four corners of the pallet 21, and the two inner sides of the lower end of the right-angle plate 22 are respectively connected to the two adjacent sides of one of the four corners of the pallet 21. And the heights of the two sides of the right-angle plate 22 are higher than the height of the workpiece. In this way, the right-angle plate 22 forms a similar right-angle enclosure relative to the pallet 21, so that the right-angle plate 22 abuts against the other two adjacent sides of the workpiece. Further, the limiting block 25 is also an L-shaped structure. One side of the limiting block 25 is slidably disposed on the pallet 21. For example, the limiting block 25 slides on the pallet 21 through a slider, so that the other side of the limiting block 25 pushes against the workpiece. The two limiting blocks 25 are respectively located at the other two ends of the pallet 21 away from the right-angle plate 22, so that the two limiting blocks 25 respectively push against the other two adjacent sides of the workpiece. In this way, when the workpiece is placed on the pallet 21, the two adjacent sides of the workpiece are respectively pushed by the two limiting members, so that the workpiece moves closer to the right-angle plate 22. When the other two adjacent sides of the workpiece are in contact with the two side edges of the inner side wall of the right-angle plate 22, the two inner sides of the right-angle plate 22 will respectively abut against the other two adjacent sides of the workpiece, so that the four sides of the workpiece are all in a state of being pushed, and further the workpiece can be firmly fixed on the pallet 21.

[0036] In one embodiment, the size of the pressing member 23 is the same as the size of the welding surface of the workpiece. The pressing member 23 is rotatably arranged on the top of the right-angle plate 22 and is located above the workpiece. Since the heights of the two sides of the right-angle plate 22 are greater than the height of the workpiece, the pressing member 23 can press the workpiece from top to bottom. Further, the telescopic member 24 is a cylinder structure, and there are two telescopic members 24. The two telescopic members 24 are respectively rotatably arranged on both sides of the right-angle plate 22, and the output ends of the two telescopic members 24 are respectively rotatably connected to both sides of the pressing member 23, so that the two telescopic members 24 drive the pressing member 23 to press or release the workpiece simultaneously. When the telescopic member 24 remains contracted, the pressing member 23 also remains in the state of pressing the workpiece. In this way, during the process of the laser mechanism 30 moving from one welding point to another welding point, the workpiece can also remain in the pressed state, so that the workpiece is fixed on the pallet 21 in the vertical direction, to prevent the equipment from being slightly collided during the welding of the workpiece, resulting in the offset of the workpiece and affecting the welding quality. Further, when the two limiting members push the workpiece to the right-angle plate 22, the workpiece is fixed on the horizontal plane of the pallet 21. In this way, the workpiece can be fixed on the pallet 21 more firmly.

[0037] As Figures 3 to 4 shown, in one embodiment, the pressing member 23 includes a pressing frame 231 and two connecting blocks 232. The two connecting blocks 232 are both arranged on the top of the right-angle plate 22, and the two connecting blocks 232 are both rotatably connected to the pressing frame 231. The output end of the telescopic member 24 is rotatably connected to the pressing frame 231.

[0038] It should be noted that the connecting block 232 includes a fixing piece 2321 and a connecting piece 2322. One end of the fixing piece 2321 is arranged on the top of the right-angle plate 22, and the other end of the fixing piece 2321 is connected to one end of the connecting piece 2322 through a pin, so that the fixing piece 2321 and the connecting piece 2322 can rotate relative to each other. The other end of the connecting piece 2322 is arranged at one end of the pressing frame 231, so that the pressing frame 231 can rotate relative to the right-angle plate 22. Further, the two telescopic members 24 are respectively rotatably arranged at both ends of the right-angle plate 22, and the output ends of the two telescopic members 24 are respectively rotatably connected to both sides of the pressing frame 231, so that the two telescopic members 24 drive the pressing frame 231 to press or release the workpiece simultaneously.

[0039] As Figures 3 to 6 shown, in one embodiment, the pressing member 23 further includes a plurality of ejector pins 2323. Each ejector pin 2323 is arranged on the pressing frame 231, and the pressing frame 231 is used to drive each ejector pin 2323 to press or release the workpiece.

[0040] It should be noted that each top column 2323 is arranged on the side of the pressing frame 231 facing the workpiece, and each top column 2323 corresponds to the non-welding point position on the workpiece. When the two telescopic members 24 drive the pressing frame 231 to press or release the workpiece simultaneously, the pressing frame 231 drives each top column 2323 to press or release the non-welding point position on the workpiece.

[0041] As Figures 3 to 6 shown, in one embodiment, a rubber head 2311 is provided at one end of the top column 2323 away from the pressing frame 231.

[0042] It should be noted that a rubber head 2311 is provided at one end of the top column 2323 away from the pressing frame 231. The purpose is that when the pressing frame 231 drives the top column 2323 to press the workpiece, it can increase the friction between the top column 2323 and the workpiece, avoid the sliding or shaking of the workpiece, so that the workpiece is more firmly fixed on the pallet 21. At the same time, since the rubber head 2311 is made of a soft material, it can avoid damaging the surface of the workpiece by the top column 2323.

[0043] As Figure 6 shown, in one embodiment, a plurality of welding holes 2312 are formed in the pressing frame 231, and each welding hole 2312 is used to clear the welding points on the workpiece.

[0044] It should be noted that a plurality of welding holes 2312 are formed in the pressing frame 231, making the pressing frame 231 in a grid shape. Each welding hole 2312 is used to clear the welding points on the workpiece. Each top column 2323 is arranged on the grid-shaped pressing frame 231, so that each top column 2323 presses the non-welding points on the workpiece. When the pressing frame 231 drives the top column 2323 to press the workpiece and fix the workpiece on the pallet 21, the laser mechanism 30 can also perform welding through the welding holes 2312. In this way, the pressing frame 231 can always maintain the state of pressing the workpiece during the welding process of the laser mechanism 30, avoiding the problem that when the laser mechanism 30 moves from one welding point to another welding point, the pressing frame 231 needs to follow the laser mechanism 30 to release from one welding point and then move to another welding point for downward pressing and fixing.

[0045] As Figure 1 、 Figure 7 shown, in one embodiment, two solid material mechanisms 20 are provided, and the laser welding device 1 further includes an alternating component 40. The alternating component 40 is arranged on the frame body 10, and both solid material mechanisms 20 are connected to the output end of the alternating component 40, so that the alternating component 40 drives the two solid material mechanisms 20 to slide alternately.

[0046] It should be noted that the alternating component 40 is arranged on the frame body 10, and both of the two solid material mechanisms 20 are arranged on the frame body 10, and the two solid material mechanisms 20 are respectively located on both sides of the alternating component 40. Both of the two solid material mechanisms 20 are connected to the output end of the alternating component 40, so that the alternating component 40 drives the two solid material components to slide alternately relative to the frame body 10. When the alternating component 40 drives one of the solid material components to slide out of the welding area, it drives the other solid material component to slide into the welding area at the same time.

[0047] As Figure 1 , Figure 7 shown, in one embodiment, the alternating component 40 includes a motor 41, a belt 42 and two belt pulleys 43. The motor 41 is arranged on the frame body 10. One of the belt pulleys 43 is arranged on the output end of the motor 41, and the other belt pulley 43 is rotatably arranged on the frame body 10. The belt 42 is sleeved on the two belt pulleys 43 respectively, and the belt 42 is connected to the two solid material mechanisms 20.

[0048] It should be noted that the motor 41 is arranged on the frame body 10. One of the belt pulleys 43 is arranged on the output end of the motor 41, and the other belt pulley 43 is rotatably arranged on the end of the frame body 10 far away from the motor 41. The belt 42 is sleeved on the two belt pulleys 43 respectively. Further, the alternating component 40 further includes two fixing blocks. Both of the two fixing blocks are arranged on the belt 42, and the two fixing blocks are respectively connected to the two solid material mechanisms 20. Since the two solid material components are both located on both sides of the alternating component 40, the motor 41 can drive the two solid material components to slide alternately.

[0049] As Figures 1 to 2 shown, in one embodiment, the laser welding device 1 further includes a loading rack 50. The loading rack 50 is arranged on one side surface of the frame body 10, and the pallet 21 slides reciprocally on the loading rack 50 and the frame body 10.

[0050] It should be noted that the loading rack 50 is arranged on one side surface of the frame body 10, and the height of the loading rack 50 is the same as that of the frame body 10. The pallet 21 slides reciprocally on the loading rack 50 and the frame body 10 through a slide rail. When the motor 41 drives the two pallets 21 to slide alternately, the workpieces on the pallets 21 can slide reciprocally and alternately on the loading rack 50 and the frame body 10. When the workpieces on the pallet 21 are welded, when the motor 41 drives the pallet 21 to slide from the frame body 10 to the loading rack 50, it also slides the workpiece on the other pallet 21 from the loading rack 50 to the frame body 10 for welding at the same time. When the workpiece on one of the pallets 21 is in the welding area, the operator can load and unload the other pallet 21. In this way, the loading and unloading work and the welding work can be carried out simultaneously to improve the production efficiency.

[0051] As Figures 1 to 2As shown, in one embodiment, the laser mechanism 30 includes a laser head 31, a transverse rail 32, and two longitudinal rails 33. The two longitudinal rails 33 are respectively arranged on the frame 10. The two ends of the transverse rail 32 are slidably arranged on the two longitudinal rails 33. The laser head 31 is slidably arranged on the transverse rail 32, and the laser head 31 vertically faces the pallet 21.

[0052] It should be noted that the laser mechanism 30 further includes a plurality of support columns 34. Each support column 34 is respectively arranged on the opposite sides of the frame 10. The two longitudinal rails 33 are respectively arranged on the support columns 34 on both sides of the frame 10, so that the two longitudinal rails 33 are higher than the solid material assembly. The two ends of the transverse rail 32 are respectively slidably arranged on the two longitudinal rails 33. The laser head 31 is slidably arranged on the transverse rail 32. The laser head 31 vertically faces the pallet 21, so that while the transverse rail 32 slides on the two longitudinal rails 33, the laser head 31 can also slide on the transverse rail 32. When the laser head 31 finishes welding the workpiece on one pallet 21, the laser head 31 can immediately move above another pallet 21 to weld the workpiece on the other pallet 21. In this way, the waiting time of the laser head 31 for the feeding of another workpiece after welding one workpiece is reduced, so as to improve the welding efficiency.

[0053] The above-described embodiments only represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
