[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] When welding rectangular plate-shaped workpieces, existing laser welding machines often require manual flipping and alignment of the workpieces, which invisibly increases safety hazards and reduces efficiency.

[0040] To this end, the present invention provides a laser welding machine that assists workpiece movement, see Figure 1 As shown, it includes a workbench 1, on which a first guide rail 2 is arranged, on which a laser welding mechanism 3 is slidably connected, the laser welding mechanism 3 includes a first mounting seat 31 slidably connected to the first guide rail 2, on which a third lifting rod 32 is fixedly connected, and on which a laser welding machine body 33 is fixedly mounted.

[0041] For details, see Figure 1 and Figure 2As shown, a rotating mechanism 4 is also provided on the workbench 1, a first lifting rod 5 is provided on the rotating mechanism 4, and a merging component 6 is provided on the first lifting rod 5 for placing and merging rectangular plate-like workpieces. The rotating mechanism 4 is used to drive the merging component 6 to rotate, and the first lifting rod 5 is used to provide lifting of the merging component 6.

[0042] Among them, Figure 2 , Figure 3 and Figure 4 As shown, the merging component 6 includes a mounting plate 61, which is fixedly connected to the top end of the first lifting rod 5. A slide groove 62 is radially provided on the mounting plate 61. Two groups of sliders 63 are symmetrically arranged around the center position in the slide groove 62. A ball 66 is rotatably connected to the bottom end of the slider 63. The slider 63 is slidably connected to the slide groove 62 through the ball 66. A support plate 64 is fixedly connected to the top end of the slider 63. Three electromagnetic suction cups 67 are evenly fixed on the support plate 64 in sequence to absorb rectangular plate-shaped workpieces. An electromagnetic block 65 corresponding to the slider 63 is fixedly connected to the center position of the slide groove 62 to absorb the slider 63 on the side corresponding to the electromagnetic block 65 and slide toward the electromagnetic block 65; as shown in FIG. Fig.12 As shown, when two rectangular plate-shaped workpieces are placed on the support plates 64 on both sides of the slide 62, it is difficult for a general person to do some straightening or other actions because they are heavy or large, and they can only be roughly placed on the support plates 64. At this time, according to the placement of the tilt angle (in Fig.12 As an example, other cases can be used as a reference), start the electromagnetic block 65 and the electromagnetic chuck 67 at b1 and the electromagnetic chuck 67 at a3 on the support plate 64, so that Fig.12 The workpiece on the right side of the middle uses the electromagnetic suction cup 67 at a3 as a support point, while there is no adsorption force at b2 and b3. In this way, when the two workpieces are close to each other, according to the principle of mechanics, it is more labor-saving and convenient for the entire electromagnetic system to assist in the alignment of the workpieces; after alignment, the remaining electromagnetic suction cups 67 can be started to adsorb the workpiece to fix it, and then the electromagnetic block 65 can adsorb the slider 63, causing the sliders 63 on both sides of the slide groove 62 to slide toward each other along the slide groove 62 until the two rectangular plate-shaped workpieces are merged and aligned, which is convenient for subsequent fixation and welding.

[0043] Further, such as Figure 1 and Figure 5As shown, two sets of second guide rails 7 are symmetrically arranged on both sides of the rotating mechanism 4 on the workbench 1, a second mounting seat 8 is arranged on the second guide rails 7, a second lifting rod 9 is arranged on the second mounting seat 8, a first installation box 10 is arranged on the second lifting rod 9, the second lifting rod 9 is used to provide lifting of the first installation box 10, a first servo motor 15 is arranged in the first installation box 10, a flip disk 11 is arranged at the output end of the first servo motor 15, the first servo motor 15 is used to drive the flip disk 11 to rotate, a driving component 13 is arranged in the flip disk 11, and the flip disk 11 is provided with a first servo motor 15. Four groups of clamping assemblies 14 are symmetrically arranged around the center of the circle 11, and the clamping assemblies 14 are connected to the driving assembly 13. The driving assembly 13 drives the two groups of clamping assemblies 14 on the same side to move toward each other to clamp the rectangular plate-shaped workpiece. In this way, after the driving assembly 13 clamps the workpiece, if it needs to be flipped, it is only necessary to release the electromagnetic suction cup 67 and the electromagnetic block 65 on the support plate 64, and then adjust the entire mounting plate 61 downward, and then drive the entire flipping plate 11 to rotate without blocking the flipping of the workpiece through the first servo motor 15, so as to complete the flipping of the entire workpiece.

[0044] It should also be added that the rotating mechanism 4 drives the mounting plate 61 to rotate. One of its main functions is to rotate the workpiece (after the clamping assembly 14 releases the workpiece) to adapt it to the welding requirements of other angles of the workpiece during welding, and secondly, to fine-tune the initial merging of the workpiece and its stage. By rotating the mounting plate 61, cooperating with the clamping of the workpiece by the clamping assembly 14, and the adsorption of the workpiece by the electromagnetic suction cup 67 and the electromagnetic block 65 on the support plate 64, the workpiece is gradually merged and aligned and adjusted parallel to the horizontal plane. It should also be noted that the worker has a button or tool to control the rotating mechanism 4, which can control the rotation angle and speed of the rotating mechanism 4, and cooperate with The clamping assembly 14 continuously adjusts the appropriate angle to finally achieve the alignment of the two rectangular plate-like workpieces and their parallelism with the horizontal plane; and there is one more point that needs to be supplemented. First, the adsorption force of the electromagnetic block 65 is large enough (emphasized below) to enable the two rectangular plate-like workpieces to move toward each other and merge. Second, the clamping assembly 14 can overcome the electromagnetic force of the electromagnetic suction cup 67 and the electromagnetic block 65. That is to say, when adjusting the two rectangular plate-like workpieces, even if the electromagnetic suction cup 67 adsorbs the workpieces and the electromagnetic block 65 also has a certain adsorption effect, the clamping assembly 14 and the second mounting seat 8 thereunder are greater than the electromagnetic force, which can ensure that it can achieve the alignment and adjustment of the workpieces.

[0045] Furthermore, Figure 2As shown, the merging component 6 mentioned above, wherein the mounting plate 61 is made of non-metallic material, so that the electromagnetic block 65 reduces the influence of the outside world when adsorbing the slider 63, and the electromagnetic block 65 is a double-sided electromagnet structure, which can ensure that both sides can adsorb the corresponding slider 63 with high magnetism to make them slide toward each other, and the adsorption force of the electromagnetic block 65 on the side opposite to the slider 63 meets the requirement of making it slide along the slide groove 62, and the electromagnetic suction cup 67 on the support plate 64 on one side of the electromagnetic block 65 and the slide groove 62 are both oppositely attracted, ensuring that while the slider 63 slides, the workpiece is adsorbed by the electromagnetic suction cup 67 on the support plate 64 and moves toward each other, thereby realizing the bonding of two rectangular plate-like workpieces.

[0046] It is also worth mentioning that a fixed plate 12 is fixedly connected to the central radial position of the flip disk 11 for pre-placing rectangular plate-like workpieces; in this way, when two rectangular plate-like workpieces are respectively placed on the support plates 64 on both sides of the slide 62, when the electromagnetic block 65 and the electromagnetic suction cup 67 on the support plate 64 are not started, the fixed plate 12 can pre-support the workpieces and ensure that the plates are in the central horizontal position of the flip disk 11, and then the rotating mechanism 4 rotates the mounting disk 61 and the adsorption effect of the electromagnetic block 65 and the electromagnetic suction cup 67, and cooperates with the clamping of the clamping assembly 14 to gradually make the two rectangular plate-like workpieces fit and align.

[0047] For details, see Figure 7 and Fig. 9 As shown, the driving assembly 13 includes a second mounting box 131 fixedly mounted in the flip disk 11, and a first mounting cavity 132 and a second mounting cavity 135 are opened in the second mounting box 131. Two second servo motors 133 are fixedly connected in the first mounting cavity 132, and the output ends of the two second servo motors 133 are fixedly connected with a first driving gear 134 and a second driving gear 136. The first driving gear 134 and the second driving gear 136 are rotatably connected in the second mounting cavity 135. The first driving gear 134 is also meshed with a first driven gear 137, and the first driven gear 137 is fixedly connected to a first mounting rod 138, and the first mounting rod 138 is rotatably connected in the second mounting cavity 135. The first driven gear 137 is meshed with a second driven gear 139, and the second driven gear 139 is fixedly connected to a second mounting rod 140, and the second mounting rod 140 is rotatably connected in the second mounting cavity 135.

[0048] like Fig. 9As shown in the rotation direction of the shear mark, one of the second servo motors 133 drives the first driving gear 134 to rotate, and then drives the first driven gear 137 to rotate, so that the first driven gear 137 rotates to drive the second driven gear 139 to rotate, and the rotation direction of the first driven gear 137 is opposite to that of the first driving gear 134, and the rotation direction of the second driven gear 139 is opposite to that of the first driven gear 137, thereby realizing the second mounting rod 140 and the clamping arm 141 on the first mounting rod 138 to move toward each other, thereby realizing the clamping action. Similarly, another second servo motor 133 drives the second driving gear 136 to rotate, and then the second driving gear 136 is used as a power source to drive the other two groups of clamping arms 141. The method is not repeated.

[0049] For further information, see Figure 8 , Fig.10 and Fig.11 As shown, the clamping assembly 14 includes a clamping arm 141, one end of the upper and lower clamping arms 141 located on the same side of the flip disk 11, and one end of the upper and lower clamping arms 141 are respectively fixedly connected to the second mounting rod 140 and the first mounting rod 138 located on the outside of the flip disk 11, and the other end of the clamping arm 141 is rotatably connected to a clamping plate 142, and a torsion spring 143 is provided at the connection between the clamping plate 142 and the clamping arm 141, one end of the torsion spring 143 is fixedly connected to the clamping plate 142, and the other end is fixedly connected to the clamping arm 141, and the torsion spring 143 always has a tendency to cause the clamping plate 142 to tend to be parallel to the horizontal plane. It should be added here that the reason why the torsion spring 143 is provided to always make the clamping plate 142 tend to be parallel to the horizontal plane is because the two corresponding clamping arms 141, during the clamping process, if the clamping plate 142 thereon is not rotatably connected to the clamping arm 141, then the angle of the clamping plate 142 should be set to the right position to be able to To ensure that it can fit with the rectangular plate-like workpiece every time it is clamped, but due to the different thicknesses of the rectangular plate-like workpieces, it is difficult to ensure that the clamping plate 142 is always completely in contact with the rectangular plate-like workpiece during the clamping process. The clamping plate 142 needs to be completely in contact with the rectangular plate-like workpiece in order to better clamp and ensure the levelness of the rectangular plate-like workpiece, which is convenient for subsequent welding work; and if the clamping plate 142 is rotatably connected to the clamping arm 141 as shown in the flip disk 11, it is necessary to ensure that the clamping plate 142 does not rotate to other angles during the clamping process of the clamping arm 141, which is inconvenient for clamping and ultimately achieving the fitting of the clamping plate 142 with the rectangular plate-like workpiece. Therefore, it is necessary to ensure that the clamping plate 142 is both rotatably connected to the clamping arm 141 and maintains a certain stable relationship with the clamping arm 141. Therefore, the design of the torsion spring 143 is added to ensure that the clamping plate 142 always tends to be parallel to the horizontal plane.

[0050] In addition, see Figure 7 and Fig. 9As shown, the other two groups of clamping arms 141 corresponding to the two groups of clamping arms 141 on the second mounting rod 140 and the first mounting rod 138 have the same driving mode as the two groups of clamping arms 141 on the second mounting rod 140 and the first mounting rod 138, and the driving source for the other two groups of clamping arms 141 to move toward each other is the second driving gear 136; it should be supplemented that the two groups of clamping arms 141 symmetrical on both sides of the flip plate 11 have a total of four clamping arms 141 in the rotating mechanism, and the clamping arms 141 on the second mounting rod 140 and the first mounting rod 138 marked in the figure have the same rotation mode and driving mode as the other two clamping arms 141 that are not marked in the figure and correspond to them, except that the power source of the unnumbered group of clamping arms 141 is the second driving gear 136, and the second driving gear 136 is driven by another second servo motor 133. Because they are both servo motors, the two groups of clamping arms 141 can move toward each other, thereby satisfying the simultaneous clamping work on both sides of the flip plate 11.

[0051] Furthermore, see Fig.10 and Fig.11 As shown, the clamping plate 142 has a T-shaped structure for clamping and straightening the plate. Due to its T-shaped structure, its bottom end can abut against the rectangular plate-like workpiece from both ends, while the horizontal end can achieve clamping, and the side in contact with the rectangular plate-like workpiece is provided with an anti-slip pad; and the bottom end of the T-shaped structure of the clamping plate 142 is made of compressible material to adapt to rectangular plate-like workpieces of lower thickness.

[0052] In addition, Figure 4 and Figure 5 As shown, slots 16 are provided on both ends of the fixed plate 12 for engaging the clamping plate 142, and the initial state of the flip disk 11 is that the fixed plate 12 is set parallel to the horizontal plane. In this way, after the rectangular plate-like workpiece is placed, it is necessary to start the clamping plate 142 to abut the two ends of the rectangular plate-like workpiece so that its side faces tend to be perpendicular to the radial direction of the flip disk 11, and then cooperate with the clamping plate 142 to continue to move towards each other to clamp the rectangular plate-like workpiece so that the rectangular plate-like workpiece tends to be parallel to the horizontal plane. In this process, if the thickness of the rectangular plate-like workpiece is relatively thin, the bottom end of the T-shaped structure of the clamping plate 142 will be inserted into the slot 16. In order to enable the horizontal end of the clamping plate 142 to clamp the workpiece, its bottom end, that is, the vertical end, can be squeezed against each other. Therefore, the bottom end of the T-shaped structure of the clamping plate 142 is made of compressible material, which is convenient for it to adapt to rectangular plate-like workpieces with lower thickness.

[0053] Working principle:

[0054] When used, two rectangular plate-shaped workpieces are placed on the support plate 64 respectively, and then pre-supported by the fixing plate 12, and then placed according to the placement conditions (refer to the above Fig.12The electromagnetic suction cup 67 and the electromagnetic block 65 on the support plate 64 are started, and then the two rectangular plate-like workpieces are adsorbed by the support plate 64, and then the electromagnetic block 65 adsorbs the slider 63, thereby driving the two rectangular plate-like workpieces to move toward each other to achieve bonding. However, although they are bonded at this time, their two ends are not necessarily aligned. At this time, the second mounting seats 8 at both ends of the workbench 1 are started to move toward each other, so that the bottom end of the T-shaped structure of the clamping plate 142, that is, the vertical end, is used to achieve the rectangular plate-like workpiece from both ends to be offset and aligned, and then the second mounting seats 8 are started. The servo motor 133 drives the clamping arms 141 on both sides to move toward each other, and the clamping arms 141 on both sides start to drive the clamping plates 142 to clamp the rectangular plate-shaped workpiece. At this time, the rotation of the rotating mechanism 4 can be coordinated to jointly limit the horizontal position of the rectangular plate-shaped workpiece, ensuring that the two workpieces are aligned and parallel to the horizontal plane. After that, the position of the rectangular plate-shaped workpiece is fixed, and the two rectangular plate-shaped workpieces are aligned and fitted. Then, the laser welding machine body 33 is welded to the rectangular plate-shaped workpiece by adjusting the first mounting seat 31 and the third lifting rod 32;

[0055] After that, it needs to be flipped. The first lifting rod 5 is adjusted to descend, and then the first servo motor 15 is started to drive the flipping disk 11 to rotate, so as to complete the flipping of the rectangular plate-like workpiece. After flipping, it is lifted back to the mounting disk 61 to fix the rectangular plate-like workpiece, and finally the welding and flipping of the rectangular plate-like workpiece are realized. If the angle of the rectangular plate-like workpiece needs to be adjusted, the clamping plate 142 can also be contacted to clamp it, and the rotating mechanism 4 can be started to drive the mounting disk 61 to rotate, so as to meet the welding requirements for adjusting the angle of the rectangular plate-like workpiece.

[0056] This effectively solves the problem that in the process of welding rectangular plate-shaped workpieces by existing laser welding machines, manual flipping and alignment of the workpieces is often required, which invisibly increases safety hazards and reduces efficiency.

[0057] The above shows and describes the basic principles, main features and advantages of the present invention.
