Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0017] The utility model provides a photovoltaic inverter welding point welding device with a structure as follows Figure 1 as well as Figure 2 As shown, it includes a carrier frame 1, and a lifting mechanism 2 is installed on the surface of the carrier frame 1. The lifting mechanism 2 is composed of a lifting screw module 21 and a servo motor 22. The lifting screw module 21 is fixedly connected to one side of the surface of the carrier frame 1, and the servo motor 22 is installed on the top of the lifting screw module 21, and the output end of the servo motor 22 is fixedly connected to the screw inside the lifting screw module 21, and a pressure sensing mechanism 3 is installed on the sliding seat of the lifting screw module 21, and the surface of the pressure sensing mechanism 3 is connected to a welding mechanism 4.

[0018] During implementation, the lifting mechanism 2 is driven to cooperate with the pressure sensing mechanism 3 to drive the welding mechanism 4 to move downward to press the welding point of the inverter substrate that needs to be heated.

[0019] Furthermore, if Figure 2 as well as Figure 3 As shown, the welding mechanism 4 is used for welding the welding points of the inverter substrate, and the pressure sensing mechanism 3 includes a fixed seat 31, a linear slide rail 32, a sensor support 33, a pressure sensor 34 and a connecting seat 35. The fixed seat 31 is fixedly connected to the sliding seat of the lifting screw module 21 by bolts, the linear slide rail 32 is fixed to the surface of the fixed seat 31, and the sliding end of the linear slide rail 32 is fixed to the connecting seat 35 by screws, the sensor support 33 is fixed to the surface of the top of the fixed seat 31 by bolts, and the pressure sensor 34 is fixed to the surface of the sensor support 33, and the bottom end of the pressure sensor 34 and the surface of the connecting seat 35 are fixedly connected to each other.

[0020] During implementation, the pressure of the electric iron 42 on the welding point is controlled by the pressure sensor 34 in the pressure sensing mechanism 3 to ensure that the pressure of each welding point is consistent. The electric iron 42 is heated for a certain period of time and rises rapidly.

[0021] Furthermore, if Figure 1 as well as Figure 3 As shown, the welding mechanism 4 is composed of a support frame 41, an electric iron 42 and a fixing block 43. The support frame 41 is fixedly connected to the surface of the connecting seat 35 by two bolts, the electric iron 42 is placed on the surface of the support frame 41, and the surface of the electric iron 42 is provided with a fixing block 43, and the fixing block 43 cooperates with the support frame 41 by two bolts to fix the electric iron 42.

[0022] During implementation, the pressure between the electric iron 42 and the welding point is sensed by the pressure sensor 34. When the pressure is too large, the servo motor 22 drives the screw of the lifting screw module 21 to rotate, so that the pressure sensing mechanism 3 drives the electric iron 42 to move upward. Similarly, when the pressure is too small, the servo motor 22 drives the screw of the lifting screw module 21 to rotate.

[0023] Working principle: When in use, first, under the drive of the lifting mechanism 2, the pressure sensing mechanism 3 drives the welding mechanism 4 to move down and press the soldering point that needs to be heated on the inverter substrate, and then the pressure sensor 34 in the pressure sensing mechanism 3 is used to control the pressure of the electric iron 42 on the soldering point to ensure that the pressure of each soldering point is consistent. The electric iron 42 is heated for a certain period of time and then rises quickly.

[0024] When the pressure sensing mechanism 3 is implemented, the pressure between the electric iron 42 and the welding point is sensed by the pressure sensor 34. When the pressure is too large, the servo motor 22 drives the screw of the lifting screw module 21 to rotate, so that the pressure sensing mechanism 3 drives the electric iron 42 to move upward. Similarly, when the pressure is too small, the servo motor 22 drives the screw of the lifting screw module 21 to rotate, so that the pressure sensing mechanism 3 drives the electric iron 42 to move downward, so that each pressure can be consistent.
