Technical Field

[0002] In the field of plastic assembly welding, when multiple plastic parts need to be connected at interlocking points, the assembled plastic parts are placed on a mold, and then a servo electric cylinder or pneumatic cylinder drives the welding unit to perform one or more welding operations on the multiple points. Hot riveting welding machines account for more than half of the market share in plastic interlocking welding, but because they mostly use single-head heating pipes to provide heat, the requirements for temperature control are high. Furthermore, if operated manually, the requirements for human safety are relatively strict.

[0003] Furthermore, in existing technologies, hot riveting welding usually requires large equipment, is inconvenient to operate, and is difficult to weld in some confined spaces or specific locations. For the welding needs of some small workpieces, existing hot riveting welding equipment often cannot meet the requirements of flexibility and portability. Utility Model Content

[0033] Please refer to this as well. Figures 1-4 The present invention discloses a handheld hot riveting welding mechanism, including a handle 1, a heat-conducting riveting welder 2, an air guiding system 3, and a temperature controller 5. The temperature controller 5 is installed on the top of the handle 1. The handle 1 is equipped with an air guiding system 3, which can guide compressed air to the heat-conducting riveting welder 2, so that the heat-conducting riveting welder 2 does not decrease in hardness due to excessive temperature.

[0034] In this embodiment, a gas guiding system 3 is installed at the bottom of the heater 4, and is connected to the front end of the temperature controller 5. The temperature controller 5 detects the temperature of the heater 4 and adjusts the hot riveting temperature accordingly. Furthermore, the tail end of the heat-conducting riveting tool 2 is connected to the heater 4, allowing a rivet to be installed at the head end of the heat-conducting riveting tool 2 and heat to be transferred to the rivet.

[0035] In some embodiments, the air guiding system 3 includes an air blower switch 31 and a quick-connect fitting 33. The output end of the air blower switch 31 is connected to a blowpipe 34, which passes through the handle 1 and is fixed to the bottom of the heater 4, continuously cooling the exterior of the thermal riveting welder 2 to prevent overheating and damage. On the other hand, the air blower switch 31 is connected to the input end of the sleeve 32. The end of the quick-connect fitting 33 is installed at the tail end of the sleeve 32, allowing for quick connection and fixation with the air pump, thereby introducing compressed airflow into the thermal riveting mechanism.

[0036] In some embodiments, the temperature controller 5 includes a temperature measuring device 51 and a housing 52. The temperature measuring end of the temperature measuring device 51 is connected to the thermally conductive riveting device 2. A display screen 53 is provided on the back of the temperature measuring device 51, which can display the temperature value measured by the temperature measuring device 51. A temperature control fluctuation switch 54 is installed on the top of the housing 52, and the temperature control fluctuation switch 54 is electrically connected to the thermally conductive riveting device 2. In this embodiment, the temperature measuring device 51 includes a thermocouple temperature sensor and a microcontroller. The thermocouple temperature sensor can convert the physical temperature signal into an electrical signal, which is transmitted to the microcontroller via serial communication. The microcontroller performs logical operations through a program pre-programmed in the microcontroller. When the measured temperature is higher than a preset value, the microcontroller disconnects the circuit through a thyristor to lower the temperature. When the temperature is lower than the preset temperature value, the microcontroller conducts current through a thyristor, thereby forming a closed-loop negative feedback regulation mode to maintain a relatively stable welding temperature.

[0037] In some embodiments, the thermal riveting device 2 includes a thermal riveting head 21 and a heat sink 23. The end of the thermal riveting head 21 is connected to one end of the thermally conductive element 22, while the other end of the thermally conductive element 22 is installed inside the heater 4. The heat sink 23 is disposed outside the thermally conductive element 22. Meanwhile, the compressed air released by the blowpipe 34 acts on the heat sink 23. In this embodiment, the thermally conductive element 22 is a tungsten alloy rod, and the end of the thermally conductive element 22 is fixedly inserted into the thermal riveting head 21, thereby transferring heat through the thermally conductive element 22.

[0038] In this embodiment, the heat sink 23 is provided with several heat dissipation holes on the outside and reinforcing ribs on the inside to improve the structural strength of the heat sink 23 and facilitate heat dissipation.

[0039] In this embodiment, the heater 4 includes a high-frequency coil and a mounting housing. The heat-conducting element 22 is inserted into the high-frequency coil, and the high-frequency coil is fixed in the mounting housing. The high-frequency coil is adapted to carry a high-frequency current, thereby forming eddy currents on the heat-conducting element 22. The eddy currents act on the heat-conducting element 22, which can quickly generate heat.

[0040] Although the present invention has been described in detail above with general descriptions and specific embodiments, some modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, all such modifications or improvements made without departing from the spirit of the present invention fall within the scope of protection claimed by the present invention.
