Microscopic Resistance Welding Spot Welding Machine

Abstract

The invention discloses a microscopic resistance welding spot welder, which comprises a spot welding head and a spot welding machine host, wherein the spot welding head includes a head frame with a front sliding shaft and a middle shaft, a front sliding shaft The lower end is provided with a welding head clamp for installing parallel electrode welding heads, and the central axis is provided with a compression spring that can be used for pre-pressurizing the electrode force. The head frame is equipped with an electrode force detection and display circuit and a preset electrode force display circuit. The force detection and display circuit is electrically connected to the preset electrode force display circuit, and the display of the detection and correction of the preset electrode force is realized through an external pressure sensor. In addition, the present invention also proposes to set the high-power consumption electronic components on the spot welding machine host, including high-power consumption electronic components, semiconductor cooling chips, heat dissipation brackets, heat dissipation fans, temperature control switches and power supplies with intelligent heat dissipation and high power consumption. Electronic components assembly.

Description

technical field [0001] The invention belongs to the field of resistance welding spot welding, and more particularly, the invention relates to a microscopic resistance welding spot welding machine. Background technique [0002] The electronic industry usually uses micro-resistance welding spot welding machines to spot welding enameled electronic components. For example, Chinese invention patent 01114785.7 discloses a "spot welding machine that can directly weld enameled wires". [0003] The prior art micro-resistance spot welding head does not have a device for detecting and correcting the force of the pre-pressurized electrode, and the pre-pressurized electrode force cannot be accurate and consistent. Furthermore, the welding head clamp in the prior art is only fixed on one front sliding shaft, the parallelism and stability are poor, the movement stroke is very small, and the tip of the welding head is likely to slip on the welding piece. In addition, due to the large amoun...

Problems solved by technology

[0003] The prior art microscopic resistance welding spot welding head does not have a device for detecting and correcting the pre-pressurized electrode force, and the pre-pressurized electrode force cannot be accurate and consistent

Furthermore, the welding head clamp in the prior art is only fixed on a front sliding shaft, the parallelism and stability are poor, the movable stroke is very small, and it is easy to cause the tip of the welding head to slip on the weldment

In addition, due to the large amount of electronic components with enameled wires, fast welding speed and long continuous working time are required, which can easily cause damage to high-power electronic components on the spot welding machine host due to poor heat dissipation
