This can achieve a comprehensive scan of large-sized workpieces, avoid missed areas of the workpiece, and improve the accuracy of laser welding. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0033] The following describes an embodiment of the present invention based on its overall structure.

[0034] Example 1: A laser welding device for the production of new energy batteries, please refer to Figure 1-12 , including a laser welding head 1, the laser welding head 1 is installed at the end of a robotic arm 14, and a laser sensor 6 for scanning the geometric information of a workpiece is installed on one side. Specifically, the robotic arm 14 is installed at one end of a workbench 13. The combination of the robotic arm 14 and the workbench 13 is a mature laser welding robot in the prior art, and its working principle is not described here. The laser sensor 6 faces the end of the laser welding head 1 and is used to scan the geometric information of the weld seam of the workpiece to be welded during the movement of the robotic arm 14, so as to facilitate the planning of the subsequent movement trajectory of the laser welding head 1. Specifically, the laser sensor 6 can adopt a 3D scanner.

[0035] It also includes a rotating table 11, which is rotatably connected to the top surface of the workbench 13. When the size of the workpiece is large, the rotating table 11 can adjust the direction of the workpiece by rotating, so that the laser sensor 6 can easily scan the side of the workpiece that is originally away from the robot arm 14, which is convenient for scanning large-sized workpieces.

[0036] In the above embodiments, please refer to Figure 1-5 The laser welding head 1 is fixedly connected to a mounting plate 2. Specifically, the mounting plate 2 is fixedly connected to the middle position of the laser welding head 1 by a plurality of screws. The mounting plate 2 is connected to a connecting plate 4 by a connecting component. The connecting component specifically includes a driving box 3.

[0037] Furthermore, positioning holes 401 and adjustment holes 402 are arranged at intervals on the connecting plate 4, and the positioning holes 401 and the adjustment holes 402 of the connecting plate 4 are both penetrated by screws and connected to the adjustment plate 5, and an arc-shaped adjustment groove 501 is arranged on the top of the adjustment plate 5, and the screw corresponding to the adjustment hole 402 can slide in the adjustment groove 501, and the center of the adjustment groove 501 coincides with the positioning hole 401, and an installation groove 502 is arranged on the bottom of the adjustment plate 5 along the length direction, and the screw passing through the installation groove 502 is fixedly connected to the laser sensor 6. Specifically, the installation groove 502 is in the shape of a waist hole, which can conveniently connect laser sensors 6 of different sizes, and the adjustment plate 5 can be rotated to adjust the inclination angle around the axis of the positioning hole 401 before being fixed, so as to adjust the direction of the laser sensor 6.

[0038] In the above embodiments, please refer to Figure 1-5 The mounting plate 2 is rotatably connected to a driving box 3, the top of the driving box 3 is rotatably connected to the connecting plate 4, the axis of the connecting plate 4 rotating shaft and the axis of the mounting plate 2 rotating shaft are projected toward the side of the workbench 13 and are orthogonal to each other, and a driving mechanism for rotating the driving box 3 and the connecting plate 4 is installed in the driving box 3, which can avoid interference with the laser welding head 1 while flipping and folding the laser sensor 6. In the present embodiment, the driving mechanism is specifically a micro dual-axis motor 7. In other undisclosed embodiments, the driving mechanism can be hydraulically driven or pneumatic.

[0039] Specifically, a micro dual-axis motor 7 is installed in the drive box 3, and the bottom end of the micro dual-axis motor 7 is connected to a drive gear 8 through a coupling structure. The mounting plate 2 is fixedly connected to a fixed gear 207 at a position rotatably connected to the drive box 3. The fixed gear 207 is meshed with the drive gear 8, and the axis coincides with the axis of the rotating shaft of the mounting plate 2. Specifically, the drive gear 8 always maintains a meshing state with the fixed gear 207. An opening is provided at the bottom end of the drive box 3 for the edge of the drive gear 8 to pass through. When the drive gear 8 rotates, since the drive box 3 and the mounting plate 2 rotate relative to each other, and the mounting plate 2 is fixedly connected to the laser welding head 1, the drive box 3 rotates around the rotating shaft of the mounting plate 2 due to its own torque.

[0040] Furthermore, the top of the micro dual-axis motor 7 is connected to a worm 9 through a coupling structure, and the worm 9 cooperates with a worm wheel 10 that is rotatably connected to the inside of the drive box 3. The rotating shaft of the worm wheel 10 extends out of the drive box 3 and is fixedly connected to the top of the connecting plate 4. The micro dual-axis motor 7 is used to synchronously drive the connecting plate 4 and the drive box 3 to move.

[0041] Example 2: A laser welding device for the production of new energy batteries, please refer to Figure 1-12On the basis of the first embodiment, the difference from the first embodiment is that a mounting chamber 201 is provided at a position of the mounting plate 2 close to the drive box 3, an electromagnet 203 is fixedly connected in the mounting chamber 201, and plug blocks 205 that can extend out of the mounting chamber 201 are slidably connected on both sides of the electromagnet 203. Specifically, the two plug blocks 205 are respectively used to limit the drive box 3 in a non-rotating state and the drive box 3 after the rotation adjustment.

[0042] Furthermore, guide rods 204 are fixedly connected on both sides of the electromagnet 203 in the installation chamber 201, and an insert block 205 is slidably connected to the guide rods 204. A compression spring 206 is provided on the insert block 205 toward the direction of the electromagnet 203. The guide rods 204 guide the sliding of the insert block 205, and the compression spring 206 can reset the insert block 205 after the electromagnet 203 is powered off.

[0043] Furthermore, the end of the plug 205 can be inserted into the drive box 3, and the electromagnet 203 is in the same power-on state as the micro dual-axis motor 7. That is to say, when the micro dual-axis motor 7 is powered on to rotate the drive box 3, the plug 205 is attracted by the electromagnet 203 and retracts into the mounting chamber 201, compressing the compression spring 206. When the micro dual-axis motor 7 is powered off, the compression spring 206 releases its elastic potential energy to reset the plug 205 and insert it back between the drive box 3 and the side wall of the mounting chamber 201, thereby restoring the limiting state of the drive box 3. When the plug 205 passes through the drive box 3 and the side wall of the mounting chamber 201 at the same time, it can limit the relative rotation between the drive box 3 and the mounting plate 2, and at the same time, the worm gear 10 is synchronously locked through the rotating shaft of the micro dual-axis motor 7 to achieve accurate resetting of the laser sensor 6.

[0044] In the above embodiments, please refer to Figure 1-9 The mounting plate 2 is provided with a receiving groove 202 on one side of the mounting bin 201. The receiving groove 202 is used to receive the drive box 3. The receiving groove 202 can prevent the drive box 3 from interfering with the mounting plate 2 during the rotation process. Specifically, after the drive box 3 completes the rotation adjustment step, the receiving groove 202 can fit together with the side wall of the drive box 3 to prevent the drive box 3 from further rotating.

[0045] Furthermore, the rotation angle of the drive box 3 is twice the rotation angle of the connecting plate 4. By adjusting the ratio of the number of teeth of the fixed gear 207 and the drive gear 8, the multiple relationship of the rotation angle of the drive box 3 and the rotation angle of the connecting plate 4 can be easily achieved. When the laser sensor 6 is folded, the drive box 3 rotates one hundred and eighty degrees away from the laser welding head 1, and the connecting plate 4 flips upward ninety degrees while the drive box 3 rotates one hundred and eighty degrees. In the process of flipping and folding the laser sensor 6 to a safe position, the displacement of the wiring port is reduced as much as possible to prevent the wires at the wiring port from loosening due to frequent folding of the laser sensor 6.

[0046] Example 3: A laser welding device for the production of new energy batteries, please refer to Figure 1-12 On the basis of the second embodiment, the difference from the second embodiment is that the workbench 13 is equipped with a lifting mechanism 12 at the bottom end of the rotating table 11. Specifically, in this embodiment, the lifting mechanism 12 can specifically adopt an electric telescopic rod, and the bottom end of the electric telescopic rod is fixedly connected to the rotating seat. The rotating seat is controlled by a servo motor or a stepper motor to rotate a set angle. The specific working principle of the rotating seat and the telescopic rod is not repeated here. After the lifting mechanism 12 lifts the rotating table 11, the part of the workpiece scanned first uses the vertical plane at the center position of the rotating table 11 as the mirror plane, and mirrors the original coordinates in the direction away from the robot arm 14, so as to realize a comprehensive scan of large-size workpieces, avoid missed scan areas of the workpiece, and improve the accuracy of laser welding.

[0047] Specifically, the lifting mechanism 12 can lift the turntable 11 to a height exceeding the thickness of the turntable 11 itself. The top surface of the turntable 11 before being lifted is flush with the top surface of the workbench 13, so that the turntable 11 can maintain the same plane as the workbench 13 when not in use, which is convenient for carrying workpieces on the workbench 13 or cleaning debris on the surface of the workbench 13.

[0048] Furthermore, the edges of the bottom surface of the rotating table 11 are all provided with chamfers, and the top of the workbench 13 is provided with an inclined surface for matching the chamfer of the bottom surface of the rotating table 11, so that the rotating table 11 can be quickly reset after rotation, and the accuracy of the reset of the rotating table 11 can also be further improved.

[0049] When the present invention is working, the mechanical arm 14 moves to make the laser sensor 6 scan the weld of the workpiece to obtain the collective information of the workpiece, and provide corresponding parameters for the movement of the laser welding head 1. After the workpiece is scanned, the micro dual-axis motor 7 in the drive box 3 is powered on, and the electromagnet 203 is powered on synchronously to make the plug 205 retract, release the limit between the drive box 3 and the mounting plate 2, and rotate around the rotating shaft of the mounting plate 2 through the mutual meshing relationship between the drive gear 8 and the fixed gear 207. At the same time, the worm gear 10 and the worm 9 cooperate with each other to make the connecting plate 4 rotate at the same time. After the drive box 3 rotates 180 degrees, the connecting plate 4 rotates 90 degrees. At this time, the laser sensor 6 and its auxiliary connecting parts are away from the laser welding head 1 to avoid affecting the laser welding head 1 from entering a narrow space to weld the weld. When the drive box 3 rotates into place, the micro dual-axis motor 7 is powered off, the electromagnet 203 is powered off, and the plug block 205 resumes the extended state. The other plug block 205 is then inserted back between the installation compartment 201 and the drive box 3 to limit the drive box 3. At the same time, the rotation of the connecting plate 4 is limited by the rotating shaft of the micro dual-axis motor 7. When the laser sensor 6 is needed, the micro dual-axis motor 7 is powered on to reset the drive box 3 and the connecting plate 4. This reciprocating motion can achieve rapid scanning and laser welding of workpieces of different sizes, effectively improving the production efficiency of new energy batteries.

The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention.
