[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0026] Refer to Figure 1 , a terminal welding auxiliary device, including a bottom plate 1. An air cushion mechanism 2 is arranged on the top of the bottom plate 1. The air cushion mechanism 2 includes an airbag 21 installed on the top of the bottom plate 1. A backing plate 22 is installed on the top of the airbag 21. An inner rubber plate 24 is installed on one side of the backing plate 22 inside the airbag 21. An electric telescopic rod 23 is connected between the outer side of the backing plate 22 and the outer side of the bottom plate 1. The electric telescopic rod 23 is used to squeeze the airbag 21, so that the gas inside the airbag 21 is compressed. The electric telescopic rod 23 is connected to a power supply. The electric telescopic rod 23 uses an existing micro electric telescopic rod 23 on the market. After the electric telescopic rod 23 is connected to the power supply, its length is shortened, so that the distance between the backing plate 22 and the bottom plate 1 is shortened, so that the gas inside the airbag 21 is squeezed, making the airbag 21 harden, further clamping the terminal, and preventing the terminal from falling off during welding.

[0027] Refer to Figure 3 , a clamping mechanism 3 is installed at the rear of the backing plate 22. The clamping mechanism 3 includes a mounting piece 31 installed on the top of the backing plate 22. An elastic strip 32 is connected to the top of the mounting piece 31. A first pressure wheel 33 is installed at the middle of the elastic strip 32. A second pressure wheel 34 is installed at the front section of the elastic strip 32. The long strip-shaped terminal is clamped, and the clamping mechanism 3 and the air cushion mechanism 2 are used together to clamp the terminal and the wire, facilitating welding. First, the long strip-shaped terminal is pushed from the front end of the elastic strip 32 to the top of the backing plate 22, so that the first pressure wheel 33 and the second pressure wheel 34 on the elastic strip 32 press on the top of the terminal, playing a role in fixing the position of the terminal.

[0028] Refer to Figure 2, a smoking mechanism 4 is installed on the outer side of the backing plate 22. The smoking mechanism 4 includes a fixing plate 41 installed on the top of the bottom plate 1. A micro air pump 42 is installed on the top of the fixing plate 41. The micro air pump 42 is connected to a smoking pipe 43. The top of the smoking pipe 43 is communicated with a smoking hood 44. The smoking hood 44 is a conical hopper for smoking. When the electric welding pen contacts the terminal and the wire, some smoke will appear. Inhaling this smoke will cause harm to the human body. The smoking mechanism 4 can be used to suck out the smoke and reduce the inhalation amount. When in use, turn on the power supply of the micro air pump 42. At this time, the micro air pump 42 sucks in the gas. The smoking hood 44 can expand the inhalation area and suck out the smoke as much as possible, playing a role in protecting the health of workers.

[0029] Working principle: When the device is in use, a long strip-shaped terminal can be clamped, and the clamping mechanism 3 and the air cushion mechanism 2 are used for clamping to clamp the terminal and the wire tightly, achieving the effect of facilitating welding. First, push the long strip-shaped terminal from the front end of the elastic strip 32 onto the top of the backing plate 22, so that the first pressing wheel 33 and the second pressing wheel 34 on the elastic strip 32 press on the top of the terminal, and the bottom of the terminal is closely attached to the top of the backing plate 22, making the welding end of the terminal face upward. At this time, connect the electric telescopic rod 23 to the power supply. The electric telescopic rod 23 uses an existing micro electric telescopic rod 23 on the market. After the electric telescopic rod 23 is connected to the power supply, its length is shortened, so that the distance between the backing plate 22 and the bottom plate 1 is shortened, and the gas inside the airbag 21 is squeezed, making the airbag 21 harden and further clamping the terminal, preventing the terminal from falling off during welding. Ensure that both ends of the long strip-shaped terminal are on the same horizontal plane during welding, and the situation of uneven solder joints may not occur during welding;

[0030] During the welding process, when the electric welding pen contacts the terminal and the wire, some smoke will appear. Inhaling this smoke will cause harm to the human body. The smoking mechanism 4 can be used to suck out the smoke and reduce the inhalation amount. When in use, turn on the power supply of the micro air pump 42. At this time, the micro air pump 42 sucks in the gas. The smoking hood 44 can expand the inhalation area and suck out the smoke as much as possible, playing a role in protecting the health of workers.

[0031] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
