[0029] Please see attached Figure 1 and attached Figure 2 A plurality of partitions 105 are arranged inside the frame body 101, and the plurality of partitions 105 divide the frame body 101 into at least three layers of chambers, so that the welding controller 2, the high current welding tool 3 and the welding transformer 6 of the plurality of groups of automatic welding components are respectively located in the three layers of chambers.

[0030] The partition 105 is used to arrange the welding controller 2, the high current welding tool 3 and the welding transformer 6 of each group of automatic welding components in layers, which is convenient for operation and control and has higher safety. The partition 105 can be made of aluminum alloy plates, acrylic plates and other plates, and can be flexibly arranged as needed. If the chamber is large, it can also be separated again by the partition 105 to facilitate the placement and use of other equipment.

[0031] Please see attached Figure 1 and attached Figure 2 The welding controller 2 and the high-current welding tool 3 are respectively located in the two-layer chamber of the upper transparent box-type structure, and the front end of the two-layer chamber where the welding controller 2 and the high-current welding tool 3 are located is open, and the rear end of the two-layer chamber where the welding controller 2 and the high-current welding tool 3 are located is installed with a transparent rear door 106.

[0042] Please see attached Figure 1 and attached Figure 2 A control panel 108 is installed in a chamber where the welding controller 2 is located. A plurality of embedded hollow portions (not shown in the figure) are formed on the control panel 108, so that the touch screens 201 of the welding controllers 2 of the plurality of automatic welding components are respectively embedded in the plurality of embedded hollow portions.

[0043] The control panel 108 is used to embed the touch screen 201 of the welding controller 2 , so that the welding personnel can control the corresponding welding controller 2 through the touch screen 201 .

[0044] Please see attached Figure 1 The welding controller 2 is fixed on the partition 105 of the chamber where it is located by a fixing clamp 202, which can improve the setting stability of the welding controller 2.

[0047] Please see attached Figure 1 and attached Figure 2 , the method of using the utility model is:

[0048] According to the welding requirements of the coil terminals of the automobile solenoid valve, two sets of automatic welding components are configured. Each set of automatic welding components outputs a large DC current (low voltage) to the high-current welding tool 3 through the welding transformer 6, and uses the positive and negative electrodes of the high-current welding tool 3 to weld the coil terminals of the automobile solenoid valve, so that it is integrated with the enameled wire wound inside it to achieve welding. Compared with traditional tin immersion welding, it is more environmentally friendly and energy-saving. Two welding stations can be configured on each high-current welding tool 3, so as to meet the welding of the coil terminals of four automobile solenoid valves and improve welding efficiency.

[0049] According to the size and quantity of the automatic welding components, the frame body 101 of the corresponding size is made of aluminum alloy bars, and the frame body 101 is divided into three layers of chambers by partitions 105. Two welding controllers 2 are respectively fixed on the partitions 105 of the uppermost chamber through fixing clamps 202, two high-current welding tools 3 are respectively fixed on the partitions 105 of the middle chamber, and two welding transformers 6 are respectively fixed on the partitions 105 in the lowermost chamber.

[0050] The welding controller 2 is used to control the process parameters such as the welding pressure of the high-current welding tool 3 , and the welding pressure of the high-current welding tool 3 can be adjusted and set through the pressure switch 203 .

[0051] When the start button 302 is pressed, the high-current welding tool 3 starts and performs high-current welding on the coil terminal of the automobile solenoid valve at a specified welding pressure. The indicator light 5 corresponding to the high-current welding tool 3 lights up to display the working state of the automatic welding assembly. The cooling mechanism 4 can be a water cooler. When the high-current welding tool 3 is working, the cooling mechanism 4 provides circulating cooling water for the cooling water path of the high-current welding tool 3 through the cooling water pipe, cools the positive and negative electrodes of the high-current welding tool 3, thereby ensuring the safe and continuous operation of the high-current welding tool 3.

[0052] During the welding process of the high-current welding tool 3, if there are dangerous situations such as workpiece falling off or human error operation, the power supply of the automatic welding component can be cut off by pressing the emergency stop button 301, thereby ensuring the safety of human operation. At the same time, the safety gratings 303 on both sides of the middle layer chamber where the two high-current welding tools 3 are located detect whether the human body parts such as hands and heads are inserted into the chamber. If detected, the safety gratings 303 trigger the safety mechanism and cut off the power supply of the entire device to further ensure the safety of human operation.

[0053] The operator can observe the operating status of the welding controller 2 and the high-current welding tool 3 and the welding status of the automobile solenoid valve through the transparent baffle 102 and the transparent rear door 106 .

[0054] The above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
