[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0031] The new energy vehicle battery pack liquid cooling plate assembly welding equipment includes a high-frequency welding host 1, a high-frequency welding extension 2, a water cooling device 3, a water inlet pipe 4, a water outlet pipe 5, an infrared thermometer 6, an induction heating coil 7, a fixture 8, and a workbench 9. The high-frequency welding host 1 and the high-frequency welding extension 2 are electrically connected through a cable, the induction heating coil 7 is electrically connected to the high-frequency welding extension 2, the induction heating coil 7 cooperates with the fixture 8, the infrared thermometer 6 is electrically connected to the high-frequency welding host 1 and corresponds to the fixture 8, the high-frequency welding extension 2 and the fixture 8 are both placed on the workbench 9, and the water inlet pipe 4 and the water outlet pipe 5 are both connected between the water cooling device 3 and the high-frequency welding host 1; the high-frequency welding host 1 includes a programmable logic controller, a foot switch 11 and an operation panel 12, and the foot switch 11, the operation panel 12, the induction heating coil 7 and the high-frequency welding extension 2 are all electrically connected to the programmable logic controller.

[0032] Welding equipment operation steps: Turn on the water cooling device 3, and the cooling water circulates and cools the high-frequency welding main unit 1 and the high-frequency welding extension unit 2 through the water inlet pipe 4. The cooling water after absorbing heat circulates again through the water outlet pipe 5 to return to the water cooling device 3, ensuring that the entire water cooling circuit is unobstructed;

[0033] Then turn on the power of the high-frequency welding host 1. When the cooling water circulation is unobstructed, the equipment enters the normal operation page. If there is a lack of water or the water pressure is weak, the equipment cannot be turned on normally, and the alarm light flashes, prompting the operator to check and deal with it. After the equipment is turned on normally, put the pre-installed product into the induction heating coil 7, and quickly clamp and fix the product with the fixture 8 to ensure that there is no shaking or deformation during the welding process of the product, and the welding distance size meets the conditions of the fixture design;

[0034] After the operation is completed, turn on the infrared thermometer 6 and set the temperature measuring point in the brazing heating area, and feed the monitoring data back to the high-frequency welding host 1 for real-time monitoring. After the adjustment is completed, start the production operation, step on the foot switch 11, and the equipment starts to run. When the infrared thermometer 6 receives the product welding melting temperature threshold, it sends a command to the high-frequency welding host 1 control system. When the system receives the signal, it stops heating and cools the pipeline. After the liquid brazing flux of the welded product cools and solidifies, release the tooling fixture 8 to take out the product and put it into the turnover vehicle to complete a product processing cycle.

[0035] Function description of the current equipment alarm system:

[0036] Overvoltage: The device allows an input voltage of 3*380V±10%. When the input voltage is too high, the device automatically stops heating and emits a continuous beep. The touch screen displays the corresponding overvoltage information.

[0037] Overcurrent: When overcurrent occurs in the high-frequency current conversion part of the equipment, the equipment automatically stops heating and emits a continuous beep, and the touch screen displays the corresponding overcurrent information; the alarm can be eliminated by turning off and then restarting the equipment (at an interval of more than 5 seconds).

[0038] Water shortage: The main components inside the equipment are cooled by water. When the cooling water pressure is insufficient, a continuous buzzing sound is emitted and the touch screen displays the corresponding water shortage information. After the water supply is improved, the alarm is naturally eliminated.

[0039] Overheating: A temperature switch is connected inside the machine to detect the water temperature. When the water temperature is too high, the temperature switch will be activated, causing the device to stop working and emit a continuous beep. The touch screen will display the corresponding overheating information.

[0040] The fixture 8 includes a first positioning mechanism 81 and a second positioning mechanism 82. The first positioning mechanism 81 includes a support frame 81a fixed on the workbench 9 and a positioning plate 81b movably connected to the support frame 81a.

At this time, the profile is pressed on the pipeline joint; the positioning hole 801 on the positioning plate 81b can be opened according to the size and shape of the profile. Similarly, the positioning groove 802 on the positioning seat 82b can also be opened according to the shape and size of the pipeline joint; the positioning plate 81b and the positioning seat 82b can be disassembled, and different types of positioning plates 81b and positioning seats 82b can be added to correspond to different types of liquid cooling plate processing.

[0042] The water inlet cooling device 3 includes a cooling water tank 31, a recovery water tank 32 and a water pump 33. The cooling water tank 31 is connected to the recovery water tank 32.
