Description

Technical Field

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

[0002] Existing ultrasonic welding is mainly spot welding, that is, the ultrasonic welding head contacts the workpiece and welds it, and then immediately loses contact with the workpiece. Its welding range is small and can only connect a small range, and it cannot achieve long-distance welding between workpieces.

[0003] Ultrasonic continuous welding requires the horn to maintain close contact with the workpiece while simultaneously moving relative to it without stopping. In existing continuous welding processes, the workpiece in contact with the horn can melt and deform, causing it to lift at the tip of the horn, affecting weldability. Furthermore, as the workpiece remains molten, continued pressure must be applied for a period of time while the horn passes through it to maintain cooling and maintain weld quality.

[0013] The lower part of the moving block is provided with a swing block via a rotating member 1, and the axial direction of the rotating member 1 is arranged along the front-back direction; the bottom surface of the moving block and the top surface of the swing block are matched with each other in a concave-convex structure.

[0037] The specific implementation of the present utility model will be described below with reference to the accompanying drawings.

[0038] like Figure 1 and Figure 2 As shown, a continuous welding execution device of this embodiment includes a back plate 1, and a lifting drive mechanism 2 is installed at intervals on the front and rear sides of the back plate 1. The bottom end of the lifting drive mechanism 2 is installed with an adjustment seat 4 through a front and rear moving adjustment mechanism 3, and the two adjustment seats 4 are respectively installed with a consolidation mechanism 5 and a pre-pressing mechanism 6; a welding head lifting mechanism 7 is installed on the back plate 1 located between the two groups of lifting drive mechanisms 2, and a welding head 8 is installed at the bottom end of the welding head lifting mechanism 7, and the welding head 8 is located between the consolidation mechanism 5 and the pre-pressing mechanism 6.

[0039] During welding, the pre-pressing mechanism 6 located in front of the welding head 8 can press down the workpiece to be welded, and the consolidation mechanism 5 located behind the welding head 8 can keep the molten part of the workpiece in a pressurized state, thereby effectively ensuring the welding quality of continuous welding.

[0040] In actual use, the distance between the consolidation mechanism 5 and the pre-pressing mechanism 6 and the welding head 8 can be adjusted through the forward and backward movement adjustment mechanism 3 according to actual use requirements to adapt to different continuous welding scenarios, thereby effectively improving the flexibility of welding use.

[0041] The bottom surface of the lifting seat 25 in the lifting drive mechanism 2 extends downward to form T-shaped ribs 31 arranged in the front and rear directions. The top surface of the adjustment seat 4 is provided with T-shaped slots 32 arranged along the front and rear directions. The T-shaped ribs 31 are fitted in the T-shaped slots 32 to form the front and rear movement adjustment mechanism 3; the threaded hole 41 passing through the adjustment seat 4 laterally is locked with a top screw, and the inner end of the top screw abuts against the T-shaped rib 31.

[0042] In actual use, loosen the top screw and apply force to the adjustment seat 4 to move it forward or backward relative to the lifting seat 25 to adjust the distance between the consolidation mechanism 5, the pre-pressing mechanism 6 and the welding head 8; after adjusting to the preset position, lock the top screw to fix the adjustment seat 4 relative to the lifting seat 25.

[0043] like Figure 3 As shown, the structure of the lifting drive mechanism 2 is as follows: it includes a lifting guide assembly 21 vertically mounted on the back plate 1, a sliding plate 23 is slidably mounted on the lifting guide assembly 21, and a lifting seat 25 is mounted on the bottom end of the sliding plate 23; it also includes a support 22 arranged across the sliding plate 23, a linear driving power 24 is mounted on the support 22, and the output end of the linear driving power 24 faces downward and is connected to the lifting seat 25.

[0044] In this embodiment, the overall structure of the lifting drive mechanism 2 is compact, ingenious and reasonable, and the mechanism layout for driving the lifting seat 25 to move up and down is realized within the limited space of the back plate 1.

[0045] In this embodiment, the lifting drive mechanism 2 can be installed on the back plate 1 via the side plate component, which is convenient for actual assembly, maintenance, and adjustment operations.

[0046] A rotating shaft 40 is installed at the lower edge of the adjustment seat 4 near the welding head 8. An arc-shaped hole 42 with the rotating shaft 40 as the center is opened on the adjustment seat 4, and a swing pin 43 is slidably fitted in the arc-shaped hole 42; the consolidation mechanism 5 and the pre-pressing mechanism 6 are respectively rotatably installed on the adjustment seat 4 by the rotating shaft 40, and the swing pin 43 is installed on the corresponding consolidation mechanism 5 or the pre-pressing mechanism 6 to form a swing limit.

[0047] In this embodiment, the adjustment seat 4 is rotatably installed via the rotating shaft 40 to install the consolidation mechanism 5 and the pre-pressing mechanism 6. Therefore, in actual welding, as the consolidation mechanism 5 and the pre-pressing mechanism 6 move down and contact the workpiece surface, they can swing toward the welding head 8 with the rotating shaft 40 as the center, thereby effectively reducing the distance between the welding head 8 and the welding head 8 during welding. This is especially suitable for situations where the upper size of the welding head 8 is larger, helping to ensure the welding quality; the assembly of the swing pin 43 and the arc-shaped hole 42 effectively limits the range of swinging of the consolidation mechanism 5 and the pre-pressing mechanism 6 toward the welding head 8.

[0048] like Figure 4As shown, the structure of the consolidation mechanism 5 is as follows: it includes a moving block 51, an upper rod 55 and a lower rod 56 are installed between the upper part of the moving block 51 and the adjustment seat 4 to rotate together, forming a parallelogram structure; the middle part of the upper rod 55 is rotatably installed on the adjustment seat 4 via the rotating shaft 40, and a swing pin 43 is installed on the upper part of the upper rod 55, and an arc-shaped hole 42 for the swing pin 43 to be equipped is provided on the adjustment seat 4; a swing block 53 is installed at the lower part of the moving block 51, and a consolidation block 54 is installed on the bottom surface of the swing block 53, and the bottom surface of the consolidation block 54 protrudes downward from the swing block 53.

[0049] In the consolidation mechanism 5 of this embodiment, the installation of the moving block 51 below the adjustment seat 4 is achieved through a parallelogram structure, which effectively ensures the levelness of the moving block 51, the swing block 53, and especially the bottom surface of the consolidation block 54, and ensures the surface-to-surface contact between the bottom surface of the consolidation block 54 and the surface of the workpiece.

[0050] A movable pin 59 is installed on the upper part of the lower rod 56, and a long hole 44 is opened on the adjustment seat 4 for the movable pin 59 to move back and forth; it also includes a V-shaped block 57, one end of the V-shaped block 57 is rotatably mounted on the adjustment seat 4 via a bolt 1 571, and the other end of the V-shaped block 57 is hung with an elastic member 58 via a bolt 2 572, and the upper end of the elastic member 58 is mounted on the adjustment seat 4; the movable pin 59 is located on the inner side of the V-shaped structure of the V-shaped block 57.

[0051] In this embodiment, by adjusting the arrangement of the long hole 44 on the seat 4 and the movable pin 59 on the lower rod 56, when a slope appears on the surface of the workpiece, Figure 5 As shown, the consolidation block 54 can be adaptively swung and adjusted in the front-to-back direction as the movable pin 59 moves in the long hole 44; through the arrangement of the V-shaped block 57 and the elastic member 58, the fit between the bottom surface of the consolidation block 54 and the slope surface of the workpiece is effectively ensured.

[0052] like Figure 6 As shown, the lower part of the moving block 51 is installed with the swing block 53 through the rotating member 1 52, and the axial direction of the rotating member 1 52 is arranged along the front-back direction; the bottom surface of the moving block 51 and the top surface of the swing block 53 are concave-convex structures and are assembled with each other.

[0053] In this embodiment, the moving block 51 is equipped with the swing block 53 via the rotating part 52 and the concave-convex structure, so that the swing block 53 can have an appropriate amount of swing margin in the left and right directions relative to the moving block 51 with the rotating part 52 as the center, so as to fit the surface of the workpiece.

[0054] The consolidation block 54 is embedded in the bottom surface of the swing block 53 , and a fastener is installed laterally through the swing block 53 , and the inner end of the fastener abuts against the consolidation block 54 .

[0055] In this embodiment, the consolidation block 54 is made of brass to ensure wear resistance.

[0056] exist Figure 1 In the embodiment shown, the consolidation mechanism 5 and the pre-pressing mechanism 6 have different structures. The consolidation mechanism 5 achieves surface contact and adhesion with the workpiece over a larger area via the bottom surface of the consolidation block 54, effectively ensuring the consolidation pressure on the workpiece.

[0057] exist Figure 2 In the embodiment shown, the consolidation mechanism 5 and the pre-pressing mechanism 6 have the same structure and are symmetrically arranged on the front and rear sides of the welding head 8. The consolidation mechanism 5 in this embodiment contacts and fits the workpiece surface via the pre-pressing roller 63.

[0058] like Figure 7 As shown, the structure of the pre-stressing mechanism 6 is as follows: it includes a swing arm 61 whose middle part is rotatably mounted on the adjustment seat 4 via the rotating shaft 40, the upper part of the swing arm 61 is mounted in the arc hole 42 of the adjustment seat 4 via the swing pin 43, and the lower part of the swing arm 61 is mounted with a roller seat 64 via the rotating part 2 62, and a pre-stressing roller 63 is rotatably mounted on the roller seat 64, and the axial direction of the pre-stressing roller 63 is arranged left and right.

[0059] In this embodiment, an elastic body, such as a torsion spring, can be installed on the rotating shaft 40. When no force is applied, the elastic body can be used to maintain the swing arm 61 at a preset angle relative to the adjustment seat 4. When force is applied, the elastic body is overcome, and the swing arm 61 swings relative to the adjustment seat 4 with the rotating shaft 40 as the center.

[0060] In this embodiment, the swing arm 61 uses a rotating part 2 62 to install the roller seat 64. The axial direction of the rotating part 2 62 is perpendicular to the axial direction of the rotating shaft 40. The rotating part 2 62 allows the roller seat 64 to have a certain rotation margin in the left and right directions relative to the swing arm 61 to adapt to the uneven surface of the welding workpiece and the fit between the pre-pressing roller 63 and the workpiece surface.

[0061] The usage of this utility model is:

[0062] Before welding, the consolidation mechanism 5, the welding head 8, and the pre-pressing mechanism 6 are all located above the workpiece 10 but not in contact with it. Figure 8 As shown, at this time, the consolidation mechanism 5 and the pre-pressing mechanism 6 are both far away from the welding head 8, so that the welding head 8 can move downward to the lowest end independently under the action of the welding head lifting mechanism 7, so that the welding head 8 can move downward to contact the workpiece for positioning.

[0063] The welding head 8 in this embodiment can be an existing standard product and matched with a standard welding machine to achieve welding. In actual application, the shape of the welding head 8 is usually larger at the top and smaller at the bottom. In order to ensure that the welding head 8 does not collide during the downward movement, the consolidation mechanism 5 and the pre-pressing mechanism 6 need to maintain a certain distance between the welding head 8.

[0064] During welding, the consolidation mechanism 5 and the pre-pressing mechanism 6 are driven by the lifting drive mechanism 2 to move downward and contact the surface of the workpiece 10. As the consolidation mechanism 5 and the pre-pressing mechanism 6 continue to move downward, the consolidation mechanism 5 and the pre-pressing mechanism 6 will be caused to rotate relative to the adjustment seat 4 toward the welding head 8 with the rotating shaft 40 as the center. Figure 9 As shown, the distance between the consolidation mechanism 5 and the pre-pressing mechanism 6 and the welding head 8 is effectively reduced, and the consolidation mechanism 5 and the pre-pressing mechanism 6 are ensured to fit and press the surface of the workpiece 10, thereby effectively ensuring the welding quality.

[0065] The utility model effectively ensures the welding quality of continuous welding; the distance between the consolidation mechanism and the pre-pressing mechanism and the welding head can be adjusted according to actual use requirements to adapt to different continuous welding scenarios, thereby effectively improving the flexibility of welding use.

[0066] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0067] The above description is an explanation of the utility model, not a limitation of the utility model. The scope of the utility model is defined by the claims. Any form of modification can be made within the scope of protection of the utility model.
