Description

Technical Field

[0001] This utility model belongs to the field of ultrasonic welding machine technology, specifically relating to an ultrasonic welding machine with an adjustable multi-welding head structure. Background Technology

[0002] An ultrasonic welding machine is a device that uses high-frequency vibration waves to be transmitted to the surfaces of two objects to be welded. Under pressure, the surfaces of the two objects rub against each other to form a fusion between molecular layers.

[0003] Its core component, the transducer, converts electrical energy into high-frequency mechanical vibration. The amplitude is amplified by the amplitude transformer and then transmitted to the welding head. The welding head then transmits the vibration energy to the surface of the material to be welded, causing the material molecules to generate heat through high-speed friction, and welding is achieved under pressure.

[0004] In the plastics industry, ultrasonic welding machines are commonly used for welding plastic toys, plastic containers, and plastic stationery, enabling fast and strong connections. In the electronics and electrical appliance field, they can weld lithium battery tabs and plastic casings for electronic components, ensuring product sealing and stability. In automotive manufacturing, they are used to weld interior parts such as dashboards and door panels, as well as automotive wiring harnesses and headlights. In the medical device industry, they can weld plastic medical consumables, such as syringes and infusion tubing, meeting the stringent requirements for hygiene, safety, and sealing in medical products. Furthermore, ultrasonic welding machines also play an important role in the packaging and non-woven fabric industries, achieving efficient and high-quality welding processes.

[0005] Existing ultrasonic welding machines require manual operation of control buttons to start and stop the equipment. However, the control buttons are directly exposed at the front of the machine body, making them easy to accidentally touch when the object to be welded is fixed on the worktable. This can lead to malfunctions of the welding machine, affecting safe operation and causing improper handling of the materials to be welded, resulting in waste of resources. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4This utility model provides the following technical solution: an ultrasonic welding machine with an adjustable multi-welding head structure, comprising an ultrasonic welding machine body 1, a welding assembly 2 mounted on the surface of the ultrasonic welding machine body 1, a welding head 3 mounted on the bottom surface of the welding assembly 2, a fixing block 4 connected to the side surface of the control button at the front end of the ultrasonic welding machine body 1, a slot for inserting a plug 5 on the surface of the fixing block 4, the other side surface of the plug 5 connected to both sides of a protective cover 6, a limiting frame 7 connected to the inner wall surface of the protective cover 6, a baffle 8 movably inserted into the inner wall surface of the limiting frame 7, a limiting rod 9 movably inserted into the bottom of the baffle 8, the bottom surface of the limiting rod 9 connected to the bottom of the inner wall of the protective cover 6, and a first spring 10 connected to the bottom surface of the inner wall of the protective cover 6. The top surface is connected to the bottom groove surface of the baffle 8, the front surface of the protective cover 6 is connected to the limiting sleeve 11, the surface of the limiting sleeve 11 is movably inserted with the crossbar 12, one side surface of the crossbar 12 is connected to the connecting ear 13, the surface of the connecting ear 13 is elastically connected to the inner wall of the protective cover 6 by the second spring 14, the front end of the protective cover 6 is movably sleeved with the pressing block 15, one end surface of the pressing block 15 is symmetrically connected with the connecting ear 13. In this design scheme, the ultrasonic welding machine body 1, the welding component 2 and the welding head 3 constitute the main body of the ultrasonic welding machine, and a large number of related components are set in the main body of the ultrasonic welding machine. Since they are existing technologies and the core content of this technical solution is irrelevant to them, they will not be described in detail in this technical solution.

[0023] The main model of the ultrasonic welding machine in this solution is: HT-9030.

[0024] In use: First, the ultrasonic welding machine body adjusts the height and position of the welding head 3 at the bottom of the welding assembly 2 according to the material, shape, size, and welding requirements of the workpiece. This adjustment is achieved using the handwheel and other devices on one side of the welding assembly 2. If necessary, a suitable welding head 3 is replaced to ensure good contact between the welding head 3 and the workpiece to be welded. Next, the workpiece is placed on the worktable, and parameters such as welding time and welding energy are set via the control panel. Then, the machine is started using the control buttons installed on the surface of the ultrasonic welding machine body 1. The pneumatic system provides pressure, causing multiple welding heads 3 to press down simultaneously and tightly adhere to the workpiece. The transducer at the top of the welding assembly 2 converts electrical energy into high-frequency mechanical vibration energy, which is transmitted to the welding head 3 via the amplitude transformer. Multiple welding heads 3 simultaneously apply high-frequency vibration to their respective welding areas, causing material molecules to rub against each other and generate heat, achieving molecular fusion under pressure. After welding is completed, the welding head 3 is lifted, and the welded workpiece is removed, completing one welding operation.

[0025] Preferably, the insert 5 is an L-shaped integrated structure with a set of semi-circular grooves symmetrically opened on its surface, the shape and size of which are adapted to the circular rubber block on the surface of the slot of the fixing block 4.

[0026] In practical use, pull the protective cover 6 to move it away from the ultrasonic welding machine body 1, so that the insert 5 disengages from the rubber protrusion in the fixed block 4. Then, move the insert 5 upward in the slot on the surface of the fixed block 4 to remove the protective cover 6 inserted in the fixed block 4.

[0027] Preferably, three sets of limiting frames 7 are evenly distributed on the inner wall of the protective cover 6. The limiting frames 7 are two U-shaped frames set opposite each other, and their inner walls form a rectangular cavity that matches the baffle 8.

[0028] In actual use, release the hand that pulls the baffle 8 upward, so that it rebounds and moves downward through the first spring 10 connected to the bottom, thereby moving vertically under the limit of the limit frame 7, and blocking the three control buttons installed at the front of the ultrasonic welding machine body 1.

[0029] Preferably, a rectangular through groove is provided at the upper end of the intersection of the protective cover 6 and the limiting frame 7, and its shape and size are adapted to the baffle 8.

[0030] In practical use, the rectangular through slot on the top of the protective cover 6 allows the limit frame 7 to move on it, thereby blocking the control buttons at the front of the ultrasonic welding machine body 1.

[0031] Preferably, the protective cover 6, the baffle 8 and the first spring 10 form an elastic connection structure.

[0032] In actual use, release the hand that pulled the baffle 8 upward, so that it rebounds and moves downward through the first spring 10 connected to the bottom, thereby moving vertically under the limit of the limit frame 7.

[0033] Preferably, the front surface of the protective cover 6 has three sets of circular through grooves, the shape and size of which are adapted to the pressing block 15, and the pressing block 15 is located at the front of the control button on the surface of the ultrasonic welding machine body 1 and is parallel to it.

[0034] In actual use, by pressing the pressing block 15 in the direction of the start button, the rubber pad attached to the rear surface of the pressing block 15 abuts against the start button at the front of the ultrasonic welding machine body 1, thereby pressing the start button and controlling the ultrasonic welding machine body 1 to start operation.

[0035] Working principle: When welding workpieces using the ultrasonic welding machine body 1, the workpieces to be welded are fixed directly below the welding head 3. Then, the processing parameters are set using the control panel installed on the ultrasonic welding machine body 1. Then, according to the processing needs, the start button is operated by pulling the baffle 8 inserted into the protective cover 6 to expose the covered start button. Then, by pressing the pressing block 15 in the direction of the start button, the rubber pad adhered to the rear surface of the pressing block 15 abuts against the start button at the front of the ultrasonic welding machine body 1, thus pressing the start button and controlling the ultrasonic welding machine body 1 to start operation.

[0036] The ultrasonic welding machine body 1 is equipped with multiple welding heads 3 to weld the workpiece. After the operation is completed, the pressing block 15 is pushed back to its original position by the second spring 14. At the same time, the crossbar 12 on the connecting ears 13 on both sides of the pressing block 15 slides forward in the limiting sleeve 11 to limit the second spring 14 and prevent it from shifting laterally. Then, the hand that pulled the baffle 8 upward is released, and it is pushed back down by the first spring 10 connected at the bottom. It moves vertically under the limit of the limiting frame 7. At the same time, the limiting rod 9 inserted in the baffle 8 guides and limits the rebound of the first spring 10 to prevent it from shifting. When it is necessary to start and stop the ultrasonic welding machine body 1, the control buttons at the corresponding positions covered by the protective cover 6 can be precisely controlled.

[0037] After prolonged use, the protective cover 6 can be pulled away from the ultrasonic welding machine body 1 and moved to the side away from the body 1, so that the insert 5 disengages from the rubber protrusion in the fixed block 4. Then, the insert 5 moves upward in the slot on the surface of the fixed block 4 to remove the protective cover 6 inserted in the fixed block 4 for replacement. When using it, the protective cover 6 made of PC (polycarbonate) material can be selected according to actual needs. It has good light transmission, high strength, and impact resistance, and allows observation of the button status. At the same time, the first spring 10 and the second spring 14 can be made of stainless steel, which is rust-proof and corrosion-resistant, suitable for environments that may come into contact with water and chemicals, ensuring that the first spring 10 and the second spring 14 work stably for a long time and are not prone to rusting and failure.

[0038] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
