Description

Technical Field

[0001] The utility model relates to the technical field of ultrasonic welding devices, in particular to ultrasonic welding equipment for medical devices. Background Art

[0002] Ultrasonic welding uses an ultrasonic generator to convert 50 / 60 Hz current into 15, 20, 30, or 40 kHz electrical energy. This high-frequency electrical energy is converted back into mechanical motion at the same frequency by a transducer. This motion is then transmitted to the welding head via a variable-amplitude horn assembly. The welding head transmits the received vibration energy to the joint of the workpieces to be welded, where it is converted into heat through friction, melting the plastic. Ultrasonic welding can be used not only to weld hard thermoplastics but also to process fabrics and films. Ultrasonic plastic welding offers fast welding speeds, high weld strength, and excellent sealing properties. Compared to traditional welding or bonding processes, it is cost-effective, clean, pollution-free, and does not damage the workpiece. However, the viewing window on the top of the ultrasonic welding machine can become dirty over time due to dust and other issues, impairing viewing. If the seal between the frame and the window is not good enough, dust can enter the ultrasonic welding machine, potentially affecting weld quality. Therefore, regular disinfection and continuous monitoring of the internal environment of the ultrasonic welding machine are necessary. Utility Model Content

[0003] The purpose of the utility model is to provide an ultrasonic welding device for medical devices to solve the problems existing in the above-mentioned prior art.

[0004] The above technical objectives of the present invention are achieved through the following technical solutions:

[0005] An ultrasonic welding device for medical devices includes an ultrasonic welding machine body, wherein a disinfection unit is arranged inside the ultrasonic welding machine body, and the disinfection unit includes an ultraviolet disinfection device, a bacteria detection device, a gas composition detection device, a spray disinfection device and a temperature and humidity detection unit. The gas composition detection device includes a gas composition analyzer, a transmission hinge and a display panel. The gas composition analyzer is arranged in the middle position inside the ultrasonic welding machine body, and the transmission hinge is fixedly installed on one side of the gas composition analyzer. A plurality of gas collectors are arranged at equal intervals on the transmission hinge.

[0006] By adopting the above technical solution, the air inside the ultrasonic welding machine body is detected to determine the content of internal bacteria and dust, so as to avoid excessive dust, which may lead to unqualified quality of medical equipment after welding. The multiple gas collectors on the transmission hinge can collect the air inside the ultrasonic welding machine body.

[0007] In a further embodiment, the gas collector includes a collection pipe, a small exhaust fan and a ventilation valve. Both ends of the collection pipe are set as open structures. The small exhaust fan is installed inside one end of the collection pipe, and the ventilation valve is set inside the other end of the collection pipe. A one-way air intake valve is provided inside the collection pipe near the end of the small exhaust fan, and the valve stem of the ventilation valve is a push-type valve stem.

[0008] In a further embodiment, a blocking rod corresponding to the valve stem of the ventilation valve is provided at the air inlet of the gas composition detection device, and a pressing plate corresponding to the valve stem of the ventilation valve is provided at the inner bottom of the ultrasonic welding machine body.

[0009] By adopting the above technical solution, because the valve stem of the ventilation valve is press-type, it is pressed when the valve stem touches the barrier rod. At this time, the gas inside the collection tube can be blown into the gas composition detection device through the small exhaust fan. When the collected product is moved to the inner bottom end of the ultrasonic welding machine body, the inner bottom gas of the ultrasonic welding machine body can be collected in the collection tube through the linkage of the pressing plate and the small exhaust fan, thereby realizing the collection and detection of the internal gas components of the ultrasonic welding machine body.

[0010] In a further embodiment, the switch of the ultraviolet disinfection device is a cycle timing switch.

[0011] In a further embodiment, the pressing plate includes a return spring fixedly connected to the inner bottom of the ultrasonic welding machine body and a pressing block arranged on the top of the return spring.

[0012] In a further embodiment, one end of the blocking rod is hingedly fixed to the gas component detection device, and the other end of the blocking rod is connected to the housing of the gas component detection device via a spring.

[0013] In summary, the present invention has the following beneficial effects:

[0014] 1. Through the air detection inside the ultrasonic welding machine body, the content of internal bacteria and dust is judged to avoid excessive dust, which leads to substandard quality of medical equipment after welding. The multiple gas collectors on the transmission hinge can effectively reduce the air inside the ultrasonic welding machine body;

[0015] 2. Because the valve stem of the air exchange valve is press-type, it is pressed when the valve stem touches the stop lever. At this time, the gas inside the collection tube can be blown into the gas composition detection device through a small exhaust fan. When the collection is moved to the inner bottom end of the ultrasonic welding machine body, the inner bottom gas of the ultrasonic welding machine body can be collected in the collection tube through the linkage of the pressing plate and the small exhaust fan, thereby realizing the effect of collecting and detecting the internal gas components of the ultrasonic welding machine body.
