[0029] In existing electron beam welders, the internal electronic components are usually soldered on the PCB circuit board. Since it is necessary to ensure the stable connection between the electronic components and the PCB circuit board and prevent loosening during later use, the welding requirements for the internal electronic components of the electron beam welder are relatively high, and it is not conducive to the maintenance and replacement of the internal electronic components of the electron beam welder, resulting in relatively high manufacturing and maintenance costs for the electron beam welder.

[0030] In view of this, the present application proposes an electron beam welder. By detachably and fixedly installing the electronic components inside the chassis, the installation positions of the various electronic components can be adjusted according to the actual situation, and it is convenient for the disassembly, installation, and replacement of the components of this device in the later stage.

[0031] Refer to Figures 1 to 4 , the present application proposes an electron beam welder, including: a chassis 1, electronic components, and control connectors.

The control connection parts are used to connect the electronic components with external components and control the electronic components.

[0033] In the embodiment of the present application, referring to Figures 1 to 3 , the above-mentioned electron beam welder includes a chassis 1. The chassis 1 includes an upper housing 101, a lower housing 102, a front box plate 103 and a rear box plate 104. The cross-sections of the upper housing 101 and the lower housing 102 are both U-shaped, and the openings of the upper housing 101 and the lower housing 102 are opposite to each other to form a housing with openings at the front and rear.

The two ends of the bearing plate 2 are respectively fixedly installed at the middle positions of the front box plate 103 and the rear box plate 104 by screws. The bearing plate 2 is used to bear and install the electronic components.

[0037] Referring to Figure 2 , a filter capacitor 3 and two single-tube IGBT modules 4 are arranged above the bearing plate 2. The filter capacitor 3 includes a large capacitor 301 and a small capacitor 302. The large capacitor 301 and the small capacitor 302 are two large-capacity energy storages with different withstand voltages. The filter capacitor 3 and the two single-tube IGBT modules 4 can both be detachably and fixedly installed on the top surface of the bearing plate 2.

[0038] Referring to Figure 2, below the carrier plate 2, there are provided a ring-shaped power supply transformer 5 capable of outputting two different voltages, a 18V regulated switching power supply module 6, two iron-chromium-aluminum resistance wires 7, and a high-voltage pulse arc starting transformer 8. The power supply transformer 5 is detachably and fixedly installed on the inner wall of the rear box plate 104, and the regulated switching power supply module 6 and the pulse arc starting transformer 8 can both be detachably and fixedly installed on the bottom surface of the carrier plate 2.

On the outer wall of the front box plate 103, near the above-mentioned control switches, interfaces and windows, there are all provided text labels, which are convenient for the staff to quickly master and operate this device.

[0042] Reference Figure 4 , on the top surface of the carrier plate 2, there are a plurality of mounting holes evenly distributed in a matrix, which are convenient for electronic components to be detachably installed on the carrier plate 2 through screws or snap structures, and each component can be installed at any position on the carrier plate.

[0043] The above-mentioned electronic components, such as the filter capacitor 3, two single-tube IGBT modules 4, the power supply transformer 5, the regulated switching power supply module 6, two resistance wires 7, the pulse arc starting transformer 8, two high-power rectifier bridges, the MCU control main board, as well as the power interface, the power display window, the power selection toggle switch, the power adjustment encoder, the power switch, the working indicator light, the switch control interface, and the voltage output insulating terminals, are all connected by wires.

[0044] When this device is in use, the external 220V AC power is input to the power supply transformer. The power supply transformer outputs 110V and 16V, which are respectively connected to two rectifier bridge stacks. After rectification by the rectifier bridge stacks, the two capacitors are filtered and energized to store energy, and 155V DC power and 23V working power are obtained. The 23V working power is supplied to the primary of the pulse arc ignition transformer through a single-tube IGBT module. The negative pole of the 155V DC power is connected to the secondary of the IGBT series pulse arc ignition transformer through a terminal as the negative charge of the welding working power supply. The positive pole of the 155V DC power is directly connected in series with the other terminal as the positive charge of the working power supply. The negative poles of the two groups of DC power are connected in parallel as the common GND. The MCU control main board outputs two-way pulses with adjustable duty cycles to control the operation of the two IGBT modules. The foot switch inputs and controls the working state of the main board. The power adjustment encoder inputs the command of the required power to the MCU.

[0045] The working principle of this device: The high-voltage pulse arc ignition transformer secondary generates 2000V high-voltage electricity to break down the air. The 155V energy storage power supply passes through the iron-chromium-aluminum resistance wire for step-down and current-limiting, and the positive and negative electron beams collide to generate high temperature to form a molten pool at the position where the jewelry workpiece needs to be welded, thus forming a weld.

[0046] The technical solution of this application detachably and fixedly installs the electronic components inside the chassis, and then connects the electronic components through wires and cables. On the premise of ensuring that each electronic component can be used normally and stably, the installation positions of the electronic components can be adjusted according to the actual situation, and it is convenient for the disassembly, installation and replacement of the components of this device in the later stage. Compared with the prior art, the electronic components in this solution are detachably installed at various positions inside the chassis through screws, snap structures, etc. Their installation positions are more flexible and the installation methods are more convenient and fast, so that the manufacturing efficiency of this device is higher, the manufacturing cost is lower, and it is also convenient for the maintenance and replacement of the electronic components in the later stage.
