Description

Technical Field

[0001] This utility model relates to the field of industrial manufacturing technology, and in particular to an ultrasonic welding machine with a protective mechanism. Background Technology

[0002] In the automotive interior manufacturing industry, which involves a large number of plastic, fabric and composite material parts, the welding process has extremely stringent requirements. It is necessary to ensure that the weld is strong, beautiful and does not damage the materials. Traditional glue bonding is prone to problems such as weak bonding and glue volatilization polluting the in-vehicle environment. In contrast, ultrasonic welding has been gradually widely used in automotive interior manufacturing due to its advantages of non-contact, high efficiency and the ability to achieve bonding at the molecular level of materials.

[0003] An ultrasonic welding machine is a device that uses high-frequency ultrasonic vibration energy to weld materials. It mainly consists of an ultrasonic generator, a transducer, and a welding head. During operation, the ultrasonic generator produces a high-frequency electrical signal, which is converted into mechanical vibration of the same frequency by the transducer. The amplitude is then amplified by the amplitude transformer and transmitted to the welding head. When the welding head contacts the surface of the material to be welded, the high-frequency vibration causes frictional heat between the material molecules, which, under pressure, promotes the fusion and welding of the materials together.

[0004] Traditional ultrasonic welding machines typically rely on manual operation during the welding process. Operators must use their experience and skills to precisely place the workpiece directly under the welding head. However, traditional ultrasonic welding machines lack a systematic and effective anti-misoperation mechanism and protective structure. In actual production, operators are susceptible to various factors. When the welding head falls according to the predetermined program, operators may not be able to remove their hands from the danger zone in time, resulting in injury from being crushed by the high-speed falling welding head. This can lead to hand fractures, severe soft tissue contusions, and other physical traumas, causing significant physical pain and seriously affecting the operational safety and production stability of the ultrasonic welding machine. Therefore, an ultrasonic welding machine with a protective mechanism is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above deficiencies, this utility model provides an ultrasonic welding machine with a protective mechanism, aiming to improve the problem of high operational safety risks caused by the lack of anti-misoperation protective structures when manually placing workpieces in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An ultrasonic welding machine with a protective mechanism includes a base, a worktable fixedly connected to the top of the base, a frame positioned directly above the worktable, a protective door on one side of the frame, a drive assembly positioned in the middle of the frame, a generator positioned directly below the drive assembly, a transducer mounted on the bottom side of the generator, a welding head mounted on the bottom side of the transducer, a mounting base and a protective frame fixedly connected to the top side of the worktable, an electric actuator mounted in the middle of the mounting base, a protective block fixedly connected to the output end of the electric actuator, a control assembly positioned in the middle of the frame, and an odor removal assembly positioned on the side of the frame away from the protective door.

[0008] As a further description of the above technical solution:

[0009] The control component includes a PLC controller, which is located on the outside of the frame, and an infrared sensor is located on the bottom side of the transducer.

[0010] As a further description of the above technical solution:

[0012] As a further description of the above technical solution:

[0013] The drive assembly includes a hydraulic rod disposed on the top side of the frame, and a connecting block is fixedly connected to the output end of the hydraulic rod.

[0014] As a further description of the above technical solution:

[0015] The protective frame has a slot in the middle, and the protective block is slidably connected to the middle of the slot.

[0016] As a further description of the above technical solution:

[0017] The protective frame has a storage frame inside, and the welding head is located directly above the protective block and the storage frame.

[0018] As a further description of the above technical solution:

[0019] The top side of the frame is equipped with a photoelectric alarm, and the protective door is provided with sound insulation cotton on the side near the frame.

[0020] As a further description of the above technical solution:

[0021] The delivery pipe is located in the middle of the frame, and the filter box is fixedly connected to the output end of the suction pump.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the protective block is pushed along the slot by the electric push rod to close the middle of the protective frame, effectively preventing the welding head from falling accidentally and avoiding the risk of hand injury to the operator. The infrared sensor and PLC controller work together to monitor the objects below in real time during the descent of the welding head. Once a non-workpiece object is detected, the descent of the welding head is stopped immediately and an alarm is triggered, realizing a multi-protection mechanism for the ultrasonic welding machine and significantly improving the operational safety of the ultrasonic welding machine.

[0024] 2. In this utility model, the odor generated during welding is drawn into the filter box for filtration by an air pump and a delivery pipe, effectively removing harmful odors generated during the welding process, reducing the emission of harmful gases in the workshop, and providing a healthier working environment for operators. The sound insulation cotton effectively isolates the noise generated during welding inside the equipment, reducing noise pollution in the workshop and reducing the damage of noise to the hearing of operators.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0032] Reference Figure 2 and Figure 3 This utility model provides an embodiment of an ultrasonic welding machine with a protective mechanism, comprising a base 1, a worktable 2 fixedly connected to the top of the base 1, a frame 3 positioned directly above the worktable 2, a protective door 4 on one side of the frame 3, a drive assembly 5 positioned in the middle of the frame 3, a generator 8 positioned directly below the drive assembly 5, a transducer 9 mounted on the bottom side of the generator 8, a welding head 10 mounted on the bottom side of the transducer 9, a mounting base 11 and a protective frame 15 fixedly connected to the top side of the worktable 2, an electric actuator 12 mounted in the middle of the mounting base 11, a protective block 13 fixedly connected to the output end of the electric actuator 12, and a control mechanism in the middle of the frame 3. The control component 17 includes an odor removal component 21 on the side of the frame 3 away from the protective door 4. The control component 17 includes a PLC controller 18, which is located on the outside of the frame 3. An infrared sensor 19 is located on the bottom side of the transducer 9. The drive component 5 includes a hydraulic rod 6, which is located on the top side of the frame 3. A connecting block 7 is fixedly connected to the output end of the hydraulic rod 6.

[0033] Specifically, the PLC controller 18 controls the drive assembly 5, causing the hydraulic rod 6 to extend, which in turn drives the connecting block 7, generator 8, transducer 9, and welding head 10 to descend synchronously. When the welding head 10 descends to a certain height, the infrared sensor 19 detects objects below in real time. If the detected object is not a workpiece, the PLC controller 18 controls the hydraulic rod 6 to stop descending. Through safety monitoring and intelligent control, personnel injury caused by misoperation is avoided, ensuring the personal safety of operators and effectively reducing the accident rate caused by operational errors. This achieves efficient prevention and control of personnel safety risks during the production process. By activating the electric actuator 12, the hydraulic rod 6 is pushed... The movable protective block 13 slides along the protective frame 15, so that the protective block 13 is tightly engaged with the slot 14, completing the sealing of the middle part of the protective frame 15, thereby effectively protecting the area where the storage frame 16 is located and preventing the welding head 10 from falling accidentally and causing injury. After the operation is completed, the protective door 4 is closed, and the protective block 13 is reset under the action of the electric push rod 12, and the equipment can continue to carry out welding work. By combining physical protection with automated control, the safety of the equipment operation process is further enhanced, so that the operator can perform operations such as picking up and placing workpieces without any worries. It achieves all-round protection against potential dangers during operation and ensures the stable operation of the ultrasonic welding machine.

[0034] Reference Figure 4 The odor removal assembly 21 includes a filter box 22, which is located on the side of the frame 3 away from the protective door 4. An air pump 23 is located on the side of the frame 3 close to the filter box 22, and a delivery pipe 24 is fixedly connected to the input end of the air pump 23.

[0035] Specifically, by starting the air pump 23 and connecting it to the welding area inside the equipment through the delivery pipe 24, the odor generated by the heating reaction of the materials during the welding process is stably drawn into the filter box 22. The filter box 22 purifies the inhaled mixed gas, effectively trapping and decomposing the harmful gas components, creating a fresh and healthy working environment for the operators.

[0036] Reference Figure 2 and Figure 3 The top side of the frame 3 is equipped with a photoelectric alarm 20, the protective door 4 is provided with sound insulation cotton 25 on the side near the frame 3, the delivery pipe 24 is located in the middle of the frame 3, and the filter box 22 is fixedly connected to the output end of the air pump 23.

[0037] Specifically, by mounting the photoelectric alarm 20 on the top side of the frame 3, when the infrared sensor 19 detects a non-workpiece object, the photoelectric alarm 20 is triggered by the PLC controller 18, which can promptly attract the operator's attention and effectively improve the safety of ultrasonic welding machine operation. The filter medium in the filter box 22 adsorbs and decomposes harmful gases, effectively removing harmful components. The sound insulation cotton 25 helps to reduce the noise generated by the ultrasonic welding machine operation.

[0038] Working principle: First, place the workpiece to be welded in the storage frame 16, start the equipment, and the PLC controller 18 controls the drive component 5 to work. The hydraulic rod 6 extends, driving the connecting block 7, generator 8, transducer 9 and welding head 10 to descend. When the welding head 10 descends to a certain height, the infrared sensor 19 detects an object below. If the detected object is not the workpiece, the PLC controller 18 immediately controls the hydraulic rod 6 to stop descending and triggers the photoelectric alarm 20 to prevent personnel injury due to misoperation.

[0039] If the operator needs to put in or take out the workpiece, open the protective door 4. At this time, the electric push rod 12 is activated, pushing the protective block 13 to engage with the slot 14 along the protective frame 15, thus completing the sealing of the middle part of the protective frame 15 and protecting the area where the storage frame 16 is located, preventing the welding head 10 from falling accidentally and causing injury. After the operation is completed and the protective door 4 is closed, the protective block 13 is reset under the action of the electric push rod 12, and the welding work can continue.

[0040] During the welding process, generator 8 generates a high-frequency electrical signal, which is converted into mechanical vibration of the same frequency by transducer 9 and transmitted to the workpiece through welding head 10 to achieve welding. The internal noise is isolated by sound insulation cotton 25. At the same time, air pump 23 is started and the welding odor is drawn into filter box 22 for filtration through delivery pipe 24.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present 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 the present utility model should be included within the protection scope of the present utility model.
