Description

Technical Field

[0001] The utility model relates to the technical field of welding, in particular to an ultrasonic welding window structure which is convenient for observation. 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, obstructing viewing. Furthermore, if the seal between the frame and the window is not adequate, dust can enter the ultrasonic welding machine, potentially affecting weld quality. Utility Model Content

[0003] The purpose of the utility model is to provide an ultrasonic welding window structure that is easy to observe, so as 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 window structure for easy observation includes an ultrasonic welding machine body, and a plurality of observation windows are provided at the top of the ultrasonic welding machine body. The observation windows include a frame, a first fixing bar, a second fixing bar, a first window and a second window. The first fixing bar is fixedly installed on one side of the frame, and the second fixing bar is fixedly installed on the other side of the frame. The first fixing bar and the second fixing bar are arranged opposite to each other. The first window is hingedly fixed to the first fixing bar, and the second window is hingedly fixed to the second fixing bar. The first window and the second window cooperate with each other to completely enclose the interior of the frame, and the surfaces where the first window and the second window contact each other are provided with sealing strips that cooperate with each other.

[0006] By adopting the above technical solution, the hinged and fixed first window and the first fixing strip have sufficient connection strength and can be conveniently opened and closed when needed. However, correspondingly, their sealing performance is insufficient. By arranging a sealing strip on the contact surface of the first window and the second window, the overall sealing performance of the ultrasonic welding device can be further improved when the two windows are closed, thereby preventing dust and foreign matter from entering the interior of the machine and ensuring the welding quality.

[0007] In a further embodiment, a groove is provided on one side of the first window close to the second window, a buckle is provided in the groove, and a corresponding lock is provided on the second window, which is used to cooperate with the buckle to lock the first window and the second window.

[0008] By adopting the above technical solution, after the first window and the second window are closed, the first window and the second window can be locked by the buckle in the first window and the lock head of the corresponding buckle on the second window.

[0009] In a further embodiment, a cleaning device for cleaning the observation window is provided inside the ultrasonic welding machine body.

[0010] By adopting the above technical solution, due to long-term use and during the welding process, the observation window may be adsorbed by dust and other stains, thereby affecting the observation effect. If the lock and window are opened for manual cleaning, on the one hand, the efficiency is low because of the size of the window, which makes cleaning inconvenient. On the other hand, after the window is opened, more pollutants may enter the interior of the device. Therefore, a cleaning device is provided inside the welding machine body to ensure the cleanliness of the observation window and prevent the interior of the device from being contaminated.

[0011] In a further embodiment, the cleaning device includes a linear drive guide rail, a roller and a drive motor, the drive motor is fixedly mounted on a slider of the linear drive guide rail, the roller is fixedly connected to the output shaft of the drive motor via a coupling, a densely covered cleaning cloth strip is bonded and fixed to the surface of the roller, and a curled edge is provided on the end of the cleaning cloth strip away from the roller.

[0012] By adopting the above technical solution, the linear drive guide rail and the drive motor can cooperate with each other, so that the roller can reciprocate along the slider on the guide rail, and the output shaft of the drive motor is fixed to the roller through a coupling to drive the roller to rotate. The cleaning cloth strips on the surface of the roller can enhance its cleaning ability and make the cleaning effect better.

[0013] In a further embodiment, the sealing strip is made of PTET material.

[0014] By adopting the above technical solution, the PTET material has good elasticity, heat resistance and corrosion resistance, and can effectively complete sealing and fixation.

[0015] In a further embodiment, a water channel is provided inside the drum, and a plurality of water channel outlets are provided on the surface of the drum.

[0016] By adopting the above technical solution, the water outlets on the surface of the drum are evenly arranged, ensuring that the water content that can be dipped onto each cleaning cloth strip during rotation is similar, thereby making the cleaning effect stable and preventing the problem of any area being not clean enough, providing better visual conditions for observing welding.

[0017] Beneficial effects:

[0018] 1. The first window and the first fixing strip fixed by the hinge have sufficient connection strength and can be opened and closed conveniently when needed. However, their sealing performance is insufficient. By providing a sealing strip on the contact surface of the first window and the second window, the overall sealing performance of the ultrasonic welding device can be further improved when the two windows are closed, thereby preventing dust and foreign matter from entering the interior of the machine and ensuring the welding quality.
