Description

An ultrasonic welding device with resistance heat assistance

Technical Field

The invention relates to the technical field of ultrasonic welding equipment, in particular to an ultrasonic welding equipment with resistance heat assistance.

Background Art

Ultrasonic welding equipment is an advanced device that uses high-frequency vibrations of tens of thousands of times per second to transmit ultrasonic energy to the welding area. In the welding area, that is, the interface between the two materials to be welded, local high temperature will be generated due to the large acoustic resistance. After applying appropriate pressure, the materials can be fused into one. When the effect of the ultrasound stops, the pressure needs to continue for several seconds to form a strong molecular chain structure, thereby achieving the purpose of welding. The strength after welding is almost comparable to the strength of the raw materials.

Patent document CN217290865U discloses an ultrasonic welding device, which belongs to the field of ultrasonic welding technology and includes a feeding mechanism; the feeding mechanism includes a positioning fixture for positioning a workpiece and a driving device for driving the positioning fixture to move from a first welding position to a second welding position along a preset path, and the distance between the first welding position and the second welding position is less than the length of the workpiece. This type of ultrasonic welding device can effectively improve the welding efficiency of workpieces.

Compared with the prior art, the beneficial effects achieved by the present invention are:

(1) The present invention ensures the perfect coordination between the equipment head, welding plate, shell structure, pressing plate, heat-conducting spring and electric heating element through a carefully designed auxiliary heating device. The electric heating element effectively transfers heat to the pressing plate with the help of the heat-conducting spring to maintain it at a constant temperature, thereby avoiding the problem of decreased welding efficiency caused by untimely temperature transfer during the welding process of wires. In addition, the synergistic effect of the electric heating element, pressing plate and heat-conducting spring further transfers heat to the pressing plate through the heat-conducting rod, thereby realizing secondary heating of the welding part and ensuring that the wire welding area is fully heated, thereby significantly improving the welding quality.

(2) The present invention realizes the precise matching of the connecting plate, the protective plate, the motor, the first belt, the double turntable, the first turntable and the circular bracket with the grinding rod through a carefully designed polishing component configuration. The grinding rod is used to finely grind the welded wires, effectively remove the burrs on the surface of the wires, ensure the neatness of the welding parts, and thus avoid the potential impact of the burrs at the welding parts of the wires on the performance of the wires. In addition, by pulling the welded wires to cooperate with the cylindrical connecting rod and utilizing the rotation mechanism of the spring sheet to move the wires, the wires are vibrated, thereby shaking off the burrs and impurities after removal. This process effectively prevents the impurity problems that may exist in the wires after welding, and ensures the optimization of the efficiency of wire use.

This measure significantly reduces the potential impact of impurities on the efficiency of wire use, thereby ensuring the performance and reliability of the wires.

(4) The present invention realizes the driving of the airflow by the rotating blades through the well-designed smoke exhaust mechanism, the coordinated work of the micro motor, the disc, the blades, the rotating rod and the square plate, and then effectively exhausts the smoke generated during the welding process through the opening of the shell. This significantly improves the welding environment for workers and effectively prevents the adverse effects of dust and smoke on work efficiency. At the same time, the close fit between the shell and the heat-insulating shell not only provides the necessary protection for the workers and avoids the risk of accidental pinching of fingers when welding wires, but also the internal heat circulation mechanism of the heat-insulating shell ensures that the wires are properly preheated during the welding process, thereby improving the welding quality and avoiding welding defects caused by rapid heating.

The smoke exhaust mechanism 3 includes a protection mechanism 4 and a micro motor 31. The protection mechanism 4 includes a shell 41. The inner wall surface of the shell 41 is provided with a heat insulating shell 42. The shell 41 protects the worker to avoid the problem of accidentally pinching the worker's hands when welding the wire. The heat insulating shell 42 circulates internal heat to keep the wire in a preheated state during welding, avoiding the problem of poor welding quality caused by rapid heating of the wire during welding. The top surface of the shell 41 is provided with an opening, and a short rod 34 is provided in the opening. The short rod 34 is rotatably installed inside the opening of the shell 41. The top and bottom surfaces of the outer wall of the short rod 34 are fixed with square plates 35.

The front of the micro motor 31 is fixed to the top of the inner wall of the insulation shell 42, the rotating shaft of the micro motor 31 is fixed with a disc 32, and the outer wall of the disc 32 is fixed with four blades 33. The rotating blades 33 blow the airflow to discharge the smoke generated during welding through the opening of the shell 41, so as to avoid the problem of low efficiency caused by the dust and smoke generated by the workers during welding.

When in use, the equipment is designed with full consideration of the safety of the staff and the welding efficiency. During the welding process, the staff needs to put two wires to be welded through the wire inlet of the shell 41. The design of the shell 41 is to provide the staff with necessary protection to prevent accidental pinching of fingers during welding. The shell structure 52 transfers heat to the heat-conducting spring 54 and the heat-conducting rod 56 by activating the electric heating element 55, thereby keeping the pressing plate 53 in a suitable heat-insulating state. This design effectively avoids the problem of reduced efficiency caused by slow temperature transfer during welding.

The function of the heat-insulating shell 42 is to circulate internal heat and ensure that the wire is in a preheated state before welding, thereby avoiding the degradation of welding quality due to rapid heating during welding. After starting the ultrasonic extrusion device of the main frame 1, the equipment head 8 will slide forward to the welding plate 51 and apply pressure to the welding area of the wire. At the same time, the kinetic energy will be transferred to the pressing plate 53, causing it to move forward and contact the heat-conducting rod 56, thereby realizing secondary heating of the welding part and further improving the welding quality.

While welding the wire, the micro motor 31 is started, and the air flow is blown out through a series of transmission components, such as the disc 32 and the blades 33, to effectively remove the smoke and dust generated during the welding process, thereby ensuring the health of the workers and the welding efficiency. After the welding is completed, the workers can easily pull the wire to the track of the shell 41 and pull it upwards. The design of the arc track can reduce the labor intensity of the workers and improve work efficiency.

In addition, after the motor 65 of the protective plate 62 is started, a series of transmission components, such as the double turntable 67, the first belt 66, the first turntable 68, etc., are used to drive the grinding rod 64 to rotate, so as to grind the welded wires and remove burrs to ensure the use effect of the wires. At the same time, the motor 65 also drives the second belt 71, the second turntable 72, the glue bracket 73 shaft and other components to achieve the attachment of the protective glue 74 to the welded wires to prevent impurities from entering and ensure the use efficiency of the wires.

After the welding process is completed, the square plate 35 is pressed down, and the square plate 35 is rotated and closed through the transmission of the short rod 34, which plays a role in protecting the machine and extending the service life of the equipment.
