Description

Technical Field

[0001] This utility model relates to the field of hot riveting machine technology, and in particular to an ultrasonic hot riveting machine for rapid assembly of washing machine control panels. Background Technology

[0002] An ultrasonic hot riveting machine is a device that uses ultrasonic vibration energy and hot riveting technology. It is mainly used for welding thermoplastic materials. It uses ultrasonic vibration to generate friction at the material contact surface. Due to the friction, heat is generated, which can soften or melt the plastic. Then, hot pressing and other operations are performed to shape the plastic, thereby achieving the purpose of riveting.

[0003] Ultrasonic hot riveting machines require very precise control of time and pressure during hot riveting. However, the actual processing is not always perfect. If the heating time is slightly longer or the pressure is too high, local high-temperature carbonization can occur on the plastic, which greatly affects the appearance and sealing performance, resulting in a decline in the overall quality of the hot riveting and, in severe cases, affecting subsequent use.

[0004] Therefore, how to provide an ultrasonic hot riveting machine for rapid assembly of washing machine control panels is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] One objective of this invention is to provide an ultrasonic hot riveting machine for rapid assembly of a washing machine control panel. This invention solves the problem in existing hot riveting technologies that if the heating time is slightly longer or the pressure is slightly higher, local high-temperature carbonization will occur on the plastic, affecting the aesthetics, sealing performance and quality.

[0006] An ultrasonic hot riveting machine for rapid assembly of a washing machine control panel according to an embodiment of the present invention includes a frame and a hot riveting frame. The hot riveting frame is disposed on the top of the frame, and a hot riveting assembly is disposed on the hot riveting frame. A cooling assembly for cooling the processed plastic parts is disposed on the surface of the hot riveting assembly near the end.

[0007] The cooling assembly includes an air nozzle, a first connecting pipe, a docking component, and a pressurizing air pump. The air nozzle is disposed on the docking component, the docking component is disposed on the first connecting pipe, the docking component is fixed to the surface of the heat riveting assembly, and the end of the first connecting pipe away from the docking component is disposed at the output port of the pressurizing air pump.

[0008] The docking component is an annular tube with four air nozzles, which are tilted downwards. The annular tube is placed on the surface of the hot riveting assembly, and the four air nozzles are arranged in a circular array with the center of the annular tube as the array center.

[0009] The cooling assembly also includes a water tank and an ultrasonic atomizer. The water tank is disposed on the surface of the heat-riveting assembly, and the ultrasonic atomizer is disposed on the surface of the water tank and communicates with the water tank. The output port of the ultrasonic atomizer is fixedly connected to the air inlet of the pressurized air pump.

[0010] The surface of the thermal riveting assembly is also provided with a filter assembly for filtering the gas.

[0011] The filter assembly includes a filter box, a suction fan, a duct, and an annular suction tube. The filter box and the annular suction tube are both disposed on the surface of the heat-riveting assembly, and the annular suction tube is disposed at the end of the heat-riveting assembly. The suction fan is disposed on one side of the filter box. The inlet of the filter box is fixedly connected to the duct, and the other end of the duct is fixedly connected to the annular suction tube.

[0012] The filter box includes a box body and a filter element, which is an activated carbon filter element.

[0013] The beneficial effects of this utility model are:

[0014] By incorporating a cooling component, during the heating and riveting process of the plastic workpiece by the hot riveting component, the cooling component blows air onto the plastic workpiece to improve the cooling of that location, preventing plastic carbonization. This solves the problem in existing hot riveting technologies where slightly longer heating times or slightly higher pressures can lead to localized high-temperature carbonization of the plastic, affecting aesthetics, sealing, and quality.

[0015] By setting up a cooling component and adding water mist to it, the gas and water mist work together to cool the plastic workpiece, greatly improving the cooling effect.

[0016] By setting up a filter component, some harmful gases are generated during the cooling process due to the high temperature of the plastic. These gases are condensed by the water mist during the cooling process and then absorbed and filtered by the filter component, thus preventing harmful substances from being directly released into the surrounding environment and causing health problems to the workers.

[0023] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0024] refer to Figure 1-4 In this embodiment, a frame 1 and a hot riveting frame 2 are included. The hot riveting frame 2 is disposed on the top of the frame 1. A hot riveting assembly 3 is disposed on the hot riveting frame 2. The hot riveting assembly 3 is a prior art assembly and will not be described in detail here.

[0025] A cooling component 4 for cooling the processed plastic part is provided near the end of the surface of the hot riveting assembly 3. The cooling component 4 includes air nozzles 5, a first connecting pipe 6, a connecting piece 7, and a pressurizing air pump 8. The air nozzles 5 are mounted on the connecting piece 7, which is mounted on the first connecting pipe 6 and fixed to the surface of the hot riveting assembly 3. The end of the first connecting pipe 6 away from the connecting piece 7 is located at the output port of the pressurizing air pump 8. The connecting piece 7 is an annular tube. There are four air nozzles 5, which are inclined downwards. The annular tube is located on the surface of the hot riveting assembly 3. The air nozzles 5 are arranged in a ring array with the center of the annular tube as the array center. This distribution can make the gas spray very evenly, so as to effectively cool down the high temperature position in the first time. During operation, the pressurized air pump 8 is started after the hot riveting. The pressurized air pump 8 will compress the gas to generate a high-speed airflow. After the high-speed airflow is generated, it enters the first connecting pipe 6, and then the high-speed airflow reaches the mating part 7 and the air nozzles 5 from the first connecting pipe 6. Finally, it is sprayed out through the air nozzles 5 to realize the first step of cooling down the plastic workpiece at the hot riveting position after the hot riveting work is completed.

[0026] refer to Figure 1-4In this embodiment, the cooling assembly 4 also includes a water tank 9 and an ultrasonic atomizer 10. The water tank 9 is disposed on the surface of the heat-riveting assembly 3, and the ultrasonic atomizer 10 is disposed on the surface of the water tank 9 and communicates with the water tank 9. The output port of the ultrasonic atomizer 10 is fixedly connected to the air inlet of the pressurized air pump 8. In order to achieve a better cooling effect, the ultrasonic atomizer 10 is provided here. When the ultrasonic atomizer 10 is activated, it generates water mist from the water in the water tank 9. The water mist enters the pressurized air pump 8 and mixes with the air. In this way, the mixed gas with water mist reaches the heat-riveting position for cooling treatment. It should be noted that the water mist can form a cooling effect while not easily causing water to enter the washing machine control panel. The amount of water mist is controlled by the ultrasonic atomizer 10.

[0027] refer to Figure 1-4 In this embodiment, the surface of the hot riveting assembly 3 is also provided with a filter assembly 11 for filtering gas. The filter assembly 11 includes a filter box 12, a suction fan 13, a conduit 14, and an annular suction tube 15. The filter box 12 and the annular suction tube 15 are both provided on the surface of the hot riveting assembly 3, and the annular suction tube 15 is provided at the end of the hot riveting assembly 3. The suction fan 13 is provided on one side of the filter box 12. The inlet of the filter box 12 is fixedly connected to the conduit 14, and the other end of the conduit 14 is fixedly connected to the annular suction tube 15. The filter box 12 includes a box body 16 and a filter element 17. The filter element 17 is an activated carbon filter element to achieve better adsorption and filtration effects. During operation, after cooling, the gas with water mist condenses the harmful gas generated by the high temperature of the plastic workpiece. Then, the suction fan 13 starts to suck up the gas. After condensation, the harmful gas passes through the annular suction tube 15 and the conduit 14 to reach the filter box 12 for filtration. The filtered gas is discharged through the suction fan 13, thus achieving the effect of filtering harmful gas.
