Embodiment 1

[0122] In this example, please refer to image 3 , the heat dissipation unit 300 is a metal heat dissipation block; the metal heat dissipation block is connected to the end of the wire gathering structure 100 and the wire pressing structure close to the welding workpiece, and the metal heat dissipation block is in contact with the workpiece to be welded.

[0123] It should be noted that, the heat dissipation unit 300 is set as the metal heat dissipation fast, because the thermal conductivity of the metal is high, in the welding application with large pressure, large amplitude and large cross-sectional area, using the metal heat dissipation block to contact the welding workpiece can quickly Take away the heat of the welding workpiece surface, thereby reducing the problem of discoloration of the welding workpiece surface during ultrasonic welding.

[0124] It can be understood that the metal heat dissipation block is connected to the wire gathering structure 100 and the end of t...

Embodiment 2

[0129] In this embodiment, the heat dissipating unit 300 may be a metal heat dissipating block, which is disposed on one end of the wire gathering structure 100 and the wire crimping structure close to the welding workpiece. Several through holes are opened on the metal heat dissipation block.

[0130] In the embodiment of the present invention, through holes are provided on the metal heat dissipation block, so that when the metal heat dissipation block is in close contact with the welded workpiece, heat dissipation can be effectively performed, so as to further improve the heat dissipation efficiency.

[0131] When this embodiment is used, a workpiece is positioned and welded by the wire-gathering structure 100 and the wire-pressing structure, and then the welding workpiece is pressed to start ultrasonic welding. During the ultrasonic welding process, the surface temperature of the welded workpiece increases continuously. At the same time, the heat dissipation unit 300 is al...

Embodiment 3

[0136] In this embodiment, the heat dissipation unit 300 may be a metal heat dissipation block, and a plurality of heat dissipation pipes are opened on the metal heat dissipation block, and the heat dissipation pipes pass through the pipes and the refrigerant storage mechanism (for example, the cold water storage tank) through the power source. (eg a pump). When in use, when the metal heat dissipation block is close to the welded workpiece, the staff can control to turn on the power source (such as a pump), so that the refrigerant in the refrigerant storage mechanism (such as a cold water storage tank) is driven into the heat dissipation pipe , so as to take away the heat on the metal heat sink and further improve the cooling efficiency.

[0137]In the embodiment of the present invention, a heat dissipation pipe is opened on the above-mentioned metal heat dissipation block, so that when the workpiece is close to the welded workpiece, the staff can operate the power source to p...

Abstract

The invention discloses a metal ultrasonic welding heat dissipation method and welding machine. The method comprises the following steps that first input is received under the condition of high-frequency vibration of a welding head of the metal ultrasonic welding machine; in response to the first input, the welding head of the metal ultrasonic welding machine stops high frequency vibration, and the welding head, a wire gathering structure and a wire pressing structure of the metal ultrasonic welding machine are closely attached to a welded workpiece to dissipate heat from the welded workpiece;second input is received; and in response to the second input, the wire gathering structure and the wire pressing structure move towards the direction away from the welded workpiece. According to themetal ultrasonic welding heat dissipation method and welding machine, the problems that the heat dissipation efficiency is poor, and the local discoloration, caused by heat dissipation, of the surface of the welded workpiece are solved.

Description

technical field [0001] The invention relates to the technical field of ultrasonic welding, in particular to a heat dissipation method for metal ultrasonic welding and a metal ultrasonic welding machine. Background technique [0002] At present, in the wire harness metal welding process, a metal ultrasonic welding machine is often used. When using a metal ultrasonic welding machine for welding, after the wire bundle is pressed into the specified shape by the wire gathering block, the wire crimping block and the welding head of the metal ultrasonic welding machine, the ultrasonic generator emits ultrasonic waves and passes the welding process while maintaining the set pressure. The head is transferred to the corresponding welding surface, and the ultrasonic welding is completed under the corresponding preset conditions. After the welding is completed, in order to ensure the process efficiency and heat dissipation efficiency, the metal ultrasonic welding machine immediately re...
