Embodiment Construction

[0069] The existing micro-spot welding machines in the industry have precise control over the parameters of spot welding. The ultrasonic vibration required by ultrasonic resistance welding is only an auxiliary supplement to improve the quality of solder joints. That is to say, ultrasonic resistance welding does not require ultrasonic machines. It is high and easy to manufacture. The ultrasonic host can be incorporated into the chassis of the welding host to make it together, or it can be added to the existing welding host as a self-contained body.

[0070] The ultrasonic resistance welding machine of the present invention comprises an ultrasonic host, a machine head, an ultrasonic vibrator and an electric welding host.

[0071] The oscillating circuit of the ultrasonic host produces high-frequency oscillations of 10KHz-50KHz, and the ultrasonic power and waveform meet the requirements through the post-stage and shaping amplifier integrated circuit and shaping integrated circuit...

Abstract

An ultrasound electric resistance welding welder is characterized in that a welding head is used for overlapping ultrasonic shock energy onto welding points on the base of electric resistance welding at the time of electrified welding and a time interval around the electrified welding, namely formation of the welding points relies on current energy and ultrasonic wave shock energy together. Ultrasonic shock enables surfaces of objects to be welded to abraded mutually to effectively remove paint of enameled wires on the welding points, current passes through conductors to be welded which are extruded together to enable the conductor to be heated and bonded together even melted together. Therefore, circuit boards of electronic products and tinning face or non-tinning face can obtain reliable high-quality welding points. A machine head with pressure locking enables pressure to be accurately controlled and further improves welding quality. The ultrasonic shock is used for removing paint, prestress point electric welding electrodes is not required, and the ultrasonic shock removes paint and pollution, reduces manual repairing and polishing of electrodes, thereby improving working efficiency, saving labor and enabling the electrodes to be durable in use.

Description

technical field [0001] The invention belongs to the technical field of welding production equipment for electronic products. Background technique [0002] Resistance welding and ultrasonic vibration welding [0003] Most of the welding of electronic products now uses resistance welding, especially the spot welding technology that can directly spot weld enameled wires. [0004] For details, please refer to "Spot welding machine that can directly weld enameled wire", ZL patent number 01114785.7. Resistance welding is the current passing through the welded conductors that are squeezed together, so that the surface and interior of the conductors heat up at the same time, the temperature rises and softens and sticks together, or even fuses together. [0005] UNITEK MIYACHI and HUGHES are large companies that produce resistance welding machines in the world. Guangzhou Micro Spot Welding Equipment Co., Ltd. and Zhuhai Micro Spot Welding Electronic Industry Co., Ltd. are domestic...
