Description

Technical Field

[0001] This utility model relates to the field of laser processing technology, and in particular to a follow-up clamping mechanism and welding equipment. Background Technology

[0002] In the prior art, laser welding is usually required for stacked plates, for example, application number 202210329699.0, patent title "A laser welding method for thin plate stacks and the longitudinal section weld contour shape thereof".

[0003] like Figure 1 As shown, the stacked plates themselves may undergo certain bending deformation. If the plates are metal sheets and the thickness is small, they may be dented or bent locally due to external forces. Furthermore, the bending deformation of the upper and lower plates is inconsistent. Therefore, after stacking, the upper and lower plates cannot fit tightly together, and a gap will form between them. This gap directly affects the quality of subsequent laser welding. Utility Model Content

[0004] The purpose of this utility model is to provide a follow-up pressing mechanism and welding equipment. The follow-up pressing mechanism can move synchronously with the laser processing components. By moving the follow-up pressing rollers in the Z direction, pressure is applied to the stacked plates to ensure the flatness of the stacked plates and further ensure welding accuracy and quality.

[0005] To achieve the above objectives, this application provides the following technical solution:

[0006] On the one hand, a follow-up clamping mechanism is provided, which includes:

[0007] Mounting bracket, which connects to the laser processing components;

[0008] A slide rail, which connects to the mounting bracket and extends along the Z direction;

[0011] In addition, a follow-up clamping roller is rotatably connected to the free end of the cantilever, and the rotation plane of the follow-up clamping roller is perpendicular to the X direction;

[0012] Wherein, X is the conveying direction of the laminated plate being welded by the laser processing component, Z is the height direction, and Y is the direction perpendicular to the XZ plane. When the laser processing component welds the laminated plate along the Y direction, the follower pressure roller rolls on the laminated plate and maintains pressure on the laminated plate.

[0013] Preferably, there are two sets of slide rails, cantilever arms, cylinders, and follow-up pressing rollers, and the extension and retraction power output ends of the two sets of cylinders extend or retract synchronously.

[0014] Preferably, both cantilevers are curved structures, and the bending directions of the two cantilevers are opposite.

[0015] Preferably, the follow-up clamping roller includes:

[0016] Roller body;

[0017] The bearing is disposed inside the roller body and is connected to the inner wall of the roller body;

[0018] In addition, the axle passes through the cantilever and the main body of the roller, and the positions of the two ends of the axle are respectively limited by the first limiting member and the second limiting member.

[0019] Preferably, the roller body and the bearing are arranged coaxially.

[0020] Preferably, the follow-up clamping mechanism further includes: a Y-axis driving component, which is used to drive the laser processing component;

[0021] On the other hand, a laminated plate welding equipment is also provided, characterized in that it includes: a gantry frame, a laser processing component, the above-mentioned follow-up clamping mechanism, a welding platform, a Y-axis drive component, and a Z-axis drive component;

[0022] The laser processing component is connected to the gantry frame; the laser processing component is used to output a laser beam and perform laser welding on the stacked plates on the welding platform through the laser beam; the Y-axis driving component is used to drive the laser processing component and the follow-up clamping mechanism to move synchronously along the Y-axis, and the Z-axis driving component is used to drive the laser processing component and the follow-up clamping mechanism to move synchronously along the Z-axis.

[0023] Preferably, the laminated plate welding equipment further includes: a loading platform for conveying the laminated plate P to the welding platform along the X direction; and a clamp for clamping and fixing the laminated plate.

[0024] The technical effects of this utility model are as follows:

[0025] The follow-up pressing mechanism in this invention can move synchronously with the laser processing components. It applies pressure to the stacked plates by moving the follow-up pressing rollers in the Z direction and rolls during the Y direction movement, maintaining pressure on the stacked plates to reduce or eliminate the gap between the first and second plates, ensuring the flatness of the stacked plates and further ensuring welding accuracy and quality.

[0033] To make the objectives, technical solutions and advantages of this utility model clearer, the embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0034] Example 1:

[0035] like Figures 2-3 As shown, this utility model provides a follow-up pressing mechanism 200, which includes:

[0036] Mounting bracket 1, which connects to laser processing assembly 100;

[0037] The slide rail 2 connects to the mounting bracket 1 and extends along the Z direction;

[0038] Cantilever 3, which is slidably engaged with slide rail 53;

[0039] Cylinder 4 is connected to the mounting bracket 1 and has a telescopic power output end 41 connected to the cantilever 3;

[0040] And, a follower pressure roller 5, which is rotatably connected to the free end of the cantilever 3, and the rotation plane of the follower pressure roller 5 is perpendicular to the X direction;

[0041] The follow-up clamping mechanism 200 and the laser processing component 100 are driven to move synchronously along the Y direction by the Y-direction driving component. When the laser processing component 100 welds the laminated plate P along the Y direction, the follow-up clamping roller 5 rolls on the laminated plate P and maintains pressure on the laminated plate P.

[0042] In this embodiment, X is the conveying direction of the laminated material P, Z is the height direction, and Y is the direction perpendicular to the XZ plane. Figure 4a As shown, the laminated board P includes a first board p1 and a second board p2 stacked from top to bottom.

[0043] For example, Figure 4b As shown, in this embodiment, the Y-axis driving component can be mounted on the gantry 6 to drive the entire follow-up pressing mechanism 200, the laser processing component 100, and the Z-axis driving component to move synchronously along the Y-axis. After moving into position, the Z-axis driving component drives the entire follow-up pressing mechanism 200 and the laser processing component 100 to move synchronously along the Z-axis, so that the follow-up pressing roller 5 applies pressure to the laminated plate P.

[0044] The working process of the follow-up clamping mechanism 200 in this embodiment is as follows:

[0045] The laminated sheet material P is conveyed to the welding platform 7 via the loading table 300, and the laminated sheet material P is clamped and fixed by the clamp 400.

[0046] The Z-axis drive assembly drives the laser processing assembly 100 and the follower clamping mechanism 200 to move synchronously along the Z-axis to a predetermined position. Then, the telescopic power output end 41 of the cylinder 4 extends to drive the cantilever 3 to move along the slide rail 2 toward the stacked plate P until the follower clamping roller 5 applies pressure to the stacked plate P. The Y-axis drive assembly and the Z-axis drive assembly can both drive the follower clamping mechanism 200 and the laser processing assembly 100 to move synchronously through motors, guide rails, gears, lead screws, etc. This is existing technology and will not be described in detail here.

[0047] The laser processing component 100 emits light, and the laser beam acts on the laminated material P. The Y-axis driving component drives the follower laser processing component 100 and the follower clamping mechanism 200 to move along the Y-axis to weld the laminated material P. During the welding process, the follower clamping roller 5 rolls on the laminated material P and always applies pressure to the laminated material P to reduce or eliminate the gap between the first laminated material p1 and the second laminated material p2, ensuring the flatness of the laminated material and further ensuring the welding accuracy and quality.

[0048] After the Y-axis welding is completed, the telescopic power output end 41 of the cylinder 4 retracts to drive the cantilever 3 to move along the slide rail 2 and away from the laminated plate P until the follower pressing roller 5 leaves the laminated plate P to release the pressure on the laminated plate P.

[0049] Therefore, in this embodiment, the follow-up clamping mechanism can move synchronously with the laser processing component. It applies pressure to the stacked plates by moving the follow-up clamping roller in the Z direction and rolls during the Y direction movement, maintaining pressure on the stacked plates to reduce or eliminate the gap between the first and second stacked plates, ensuring the flatness of the stacked plates and further ensuring welding accuracy and quality.

[0050] Example 2:

[0051] The only difference between this embodiment and embodiment 1 is that there are two sets of slide rail 2, cantilever 3, cylinder 4 and follow-up pressing roller 5, and the extension and retraction power output ends 41 of the two sets of cylinder 4 extend or retract synchronously to drive the two cantilever 3 to extend or retract synchronously.

[0052] Furthermore, in this embodiment, the cantilever 3 is a curved structure, and the bending directions of the two cantilever 3 are opposite, thereby shortening the distance between the two follower pressing rollers 5 to match the size of the welding area on the laminated plate P, and more effectively eliminating the gap between the first laminated plate p1 and the second laminated plate p2.

[0053] Example 3:

[0054] The only difference between this embodiment and Embodiment 1 or 2 is that, Figure 5 As shown, the follower clamping roller 5 includes:

[0055] Roller body 51;

[0056] The bearing 52 is disposed inside the roller body 51 and connected to the inner wall of the roller body 51. The roller body 51 and the bearing 52 are coaxially arranged.

[0057] In addition, the axle 53 passes through the cantilever 3 and the roller body 51, and the two ends of the axle 53 are respectively limited by the first limiting member 54 and the second limiting member 55 to prevent the axle 53 from coming out of the cantilever 3 and the roller body 51;

[0058] When the follow-up pressing roller 5 moves along the Y direction, the roller body 51 and bearing 52 rotate freely and synchronously around the wheel axle 53 to roll on the laminated plate P.

[0059] Example 4:

[0060] This embodiment provides a welding device for laminated plates, such as... Figure 6 As shown, it includes: a gantry frame 6, a laser processing component 100, a follow-up clamping mechanism 200 as described in any one of embodiments 1-3, a welding platform 7, a loading table 300, a Y-axis drive component, a Z-axis drive component, and a fixture 400;

[0061] The laser processing component 100 is connected to the gantry frame 6; the loading platform 300 is used to transport the stacked plate P to the welding platform 7 along the X direction; the clamp 400 is used to clamp and fix the stacked plate P; the laser processing component 100 is used to output a laser beam and perform laser welding on the stacked plate P on the welding platform 7 through the laser beam; the Y-direction driving component is used to drive the laser processing component 100 and the follower clamping mechanism 200 to move synchronously along the Y direction; and the Z-direction driving component is used to drive the laser processing component 100 and the follower clamping mechanism 200 to move synchronously along the Z direction.

[0062] In summary, the follow-up clamping mechanism in this application can move synchronously with the laser processing components. It applies pressure to the stacked plates by moving the follow-up clamping rollers in the Z direction and rolls during the Y direction movement, maintaining pressure on the stacked plates to reduce or eliminate the gap between the first and second plates, ensuring the flatness of the stacked plates and further ensuring welding accuracy and quality.

[0063] Where there is no conflict, the above embodiments and features described herein can be combined with each other.

[0064] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
