Description

Technical Field

[0001] This utility model discloses an applicable ultrasonic welding and cutting mechanism, belonging to the technical field of welding equipment. Background Technology

[0002] Ultrasonic welding is a joining technology that uses high-frequency vibration waves transmitted to the surfaces of two objects to be welded. Under pressure, the contact surfaces rub against each other, thereby achieving interlayer fusion. Existing ultrasonic welding machines are usually equipped with a simple cutting device. The cutter presses the material onto the ultrasonic mold, cutting it off while it is fusing, effectively completing the integrated operation of welding and cutting.

[0003] However, this technology has obvious limitations. It has certain requirements on the hardness of the material surface. When the material hardness is low, the cutting blade will cause the material to deform significantly when it is pressed down. This will significantly reduce the actual contact area between the part pressed down by the cutting blade and the ultrasonic mold. In this case, the material may be cut off before it is fully fused, resulting in welding failure and affecting product quality and production efficiency. Therefore, a new solution is needed to solve this problem. Utility Model Content

[0004] The purpose of this invention is to provide a suitable ultrasonic welding and cutting mechanism to solve the above-mentioned problems.

[0005] This utility model achieves the above-mentioned objective through the following technical solution: an applicable ultrasonic welding and cutting mechanism, comprising an ultrasonic mold and a cutting assembly, wherein the cutting assembly is disposed on a support, and a driving assembly for driving the cutting assembly is disposed on the support, the cutting assembly comprising a cutting blade, a connecting seat, a sliding rod and a pressing member, the cutting blade being connected to the driving assembly, the connecting seat being fixed to one side of the cutting blade, the sliding rod being fixed to the connecting seat, the pressing member being disposed below the cutting blade and slidably connected to the sliding rod, and the ultrasonic mold being disposed below the pressing member and aligned with the pressing member.

[0006] Preferably, a spring is fitted onto the slide rod, and the two ends of the spring abut against the connecting seat and the pressing member, respectively.

[0007] Preferably, the bottom of the pressing member is provided with a pressing protrusion, and a cutting opening is provided at the center of the pressing protrusion.

[0008] Preferably, the drive assembly includes a drive cylinder and a connecting block. The drive cylinder is fixed on the bracket, the connecting block is fixed on the output end of the drive cylinder, and the cutter is connected to the connecting block by bolts.

[0009] Preferably, the bracket includes a side support frame and a top support frame. The side support frame is vertically mounted on the platform of the equipment, the top support frame is fixed to the top of the side support frame, the drive cylinder is fixed to the top support frame, and the output end of the drive cylinder extends to the bottom of the top support frame.

[0010] Preferably, the bottom of the slide bar is provided with a limiting foot block for limiting the pressing member.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] By adding a top-pressing component structure with spring buffer to the cutting assembly, the top-pressing component pre-presses the soft material before the cutter cuts, and the pressing protrusion ensures the contact area. After the ultrasonic mold fully fuses the material, the cutter completes the cutting. This effectively solves the problem of insufficient fusion of soft materials due to insufficient contact area caused by the direct pressing of the cutter in traditional technology, and significantly improves welding quality, production efficiency and quality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. In the description of the present utility model, it should be understood that the terms "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing the present utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0019] An applicable ultrasonic welding and cutting mechanism, such as Figure 1 As shown, the device includes an ultrasonic mold 1 and a cutting component 2. The cutting component 2 is mounted on a support 3. The ultrasonic mold 1 can be positioned below the processing platform of the equipment, with its top end face aligned with the platform for easy processing. The support 3 can be positioned above the processing platform of the equipment. The support 3 is equipped with a driving component 4 for driving the cutting component 2. The driving component 4 drives the cutting component 2 to move downward and press the material towards the ultrasonic mold 1, thereby performing ultrasonic fusion and cutting.

[0020] like Figure 2 As shown, the cutting assembly 2 includes a cutter 5, a connecting seat 6, a sliding rod 7, and a pressing member 8. The cutter 5 is connected to the drive assembly 4. The connecting seat 6 is fixed to one side of the cutter 5, and the sliding rod 7 is fixed to the connecting seat 6. The pressing member 8 is located below the cutter 5 and is slidably connected to the sliding rod 7. The ultrasonic mold 1 is located below the pressing member 8 and is aligned with it. Therefore, the cutter 5 will move downward under the drive of the drive assembly 4, allowing the pressing member 8 to contact the material first, press down the material to make it fully contact the ultrasonic mold 1, and fully fuse the material. Then the cutter 5 will continue to move downward and cut the material, thus ensuring that the soft material can be fused before being cut, avoiding the problem in traditional equipment where the fusion is incomplete due to the deformation of the soft material before it is cut.

[0021] like Figure 2As shown, a spring 9 is sleeved on the slide rod 7. The two ends of the spring 9 abut against the connecting seat 6 and the pressing member 8, respectively. Therefore, under the action of the spring 9, when the pressing member 8 is pressed down to contact the material, it can provide sufficient pressure to press the material. At the same time, the spring 9 can also buffer the connecting seat 6, giving the ultrasonic mold 1 enough time to fuse the material, and also protect the pressing member 8 to prevent it from colliding directly with the connecting seat 6 during the pressing process. The bottom of the slide rod 7 is provided with a limiting foot block 16 for limiting the pressing member 8. It can limit the connecting seat 6 to prevent it from detaching from the slide rod 7. At the same time, silicone or other buffer materials can be used to ensure the stability of the pressing member 8 when it contacts the material with the cutter 5.

[0022] like Figure 3 As shown, the bottom of the top pressing member 8 is provided with a pressing protrusion 10, and a cutting opening 11 is provided at the center of the pressing protrusion 10. The pressing protrusion 10 can ensure the pressing surface of the material, so that the material and the ultrasonic mold 1 have sufficient contact area, thereby ensuring the fusion of the material. The cutting opening 11 allows the cutter 5 to pass through the top pressing member 8 and cut the material. The fact that it is located at the center of the pressing protrusion 10 can also ensure that the material on both sides of the cutter 5 has sufficient fusion area.

[0023] like Figure 4 As shown, the drive assembly 4 includes a drive cylinder 12 and a connecting block 13. The drive cylinder 12 is fixed on the bracket 3, and the connecting block 13 is fixed on the output end of the drive cylinder 12. The cutter 5 is connected to the connecting block 13 by bolts. The drive cylinder 12 is set vertically and the output end faces downward, so it can control the cutter 5 to move upward or downward, thereby driving the cutter 5 to operate.

[0024] like Figure 4 As shown, the bracket 3 includes a side support frame 14 and a top support frame 15. The side support frame 14 is vertically mounted on the table of the equipment. The top support frame 15 is fixed to the top of the side support frame 14. The drive cylinder 12 is fixed to the top support frame 15. The output end of the drive cylinder 12 extends to the bottom of the top support frame 15. This structure is simple and easy to install, and can be adapted to be installed on most equipment that requires ultrasonic welding.

[0025] The ultrasonic welding and cutting mechanism of this invention adds a top pressure member 8 with a spring 9 for buffering to the cutting component 2. Before the cutting blade 5 cuts, the top pressure member 8 pre-presses the material, and the pressing protrusion 10 on it ensures the contact area of ​​the material. During the buffering compression process of the spring 9, the ultrasonic mold 1 makes the material fully fused. Thus, when the cutting blade 5 finishes cutting, the material has already been bonded and fused. Therefore, it can be adapted to a wider variety of materials and effectively solves the problem of insufficient contact area and incomplete fusion of soft materials due to direct pressure from the cutting blade in traditional technology. It significantly improves welding quality and production efficiency.
