[0023] In order to facilitate the understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings.

[0024] This application proposes a welding positioning fixture 100, see Figure 1 and Figure 2, including: a handle 10 and a positioning part 30, the handle 10 is connected to the positioning part 30, the staff holds the handle 10, the positioning part 30 is provided with a flash slot 31 along its thickness direction, the positioning part 30 is used to align the welding position on the circuit board 41, and the flash slot 31 is used to limit the components to be welded. The flash slot 31 of the positioning part 30 is held on the position of the circuit board 41 to be welded, and solder paste is placed on the position of the circuit board 41 to be welded. When the temperature on the circuit board 41 rises to a specific temperature, the staff uses tweezers 42 to clamp the flash 43 and correctly put it into the flash slot 31, and then uses tweezers 42 to press down the top of the flash 43, thereby improving the welding efficiency and the success rate of manual welding.

[0025] Please refer again to Figure 1 Before work, the staff places the circuit board 41 on a hot plate 40 with a relatively high temperature, so that the temperature of the solder paste on the pad of the circuit board 41 increases until it is in a molten state. The positioning part 30 is set on the pad with the molten solder paste. The staff then uses tweezers 42 to clamp the flash 43 and correctly put it into the flash slot 31. After the temperature cools down, the flash 43 is electrically connected to the pad.

[0026] In one embodiment, the positioning portion 30 is provided with a first flash slot 31 and a second flash slot 31 along its thickness direction. The sizes of the first flash slot 31 and the second flash slot 31 are different, so that two different flashes 43 can be welded and positioned in one clamp, thereby improving the versatility of the clamp and being able to adapt to more work scenarios.

[0027] Furthermore, since the sizes of flash43 of different models are different, the handle 10 and the positioning portion 30 are detachably connected, so that the handle 10 can be replaced with positioning portions 30 of different sizes, that is, the sizes of the flash slots 31 are different, and then the clamp can weld and position different flash43, thereby improving the versatility of the clamp and saving the material of the handle 10.

[0028] In one embodiment, an anti-skid pad is provided on the working contact surface between the positioning portion 30 and the circuit board 41. The anti-skid pad can increase the maximum static friction between the bottom surface of the positioning portion 30 and the circuit board 41, making the positioning between the two more stable, thereby avoiding displacement and improving the accuracy of welding.

[0029] For further information, see Figure 1 The angle between the handle 10 and the positioning portion 30 is set to be an obtuse angle, so that the welding personnel can use tweezers 42 to put the flash 43 into the flash slot 31 for operation.

[0030] Preferably, the angle between the handle 10 and the positioning portion 30 is 135°.

[0031] In another embodiment, the working contact surface of the positioning portion 30 and the circuit board 41 is arranged parallel to the welding surface of the circuit board 41. When the flash 43 is placed in the flash slot 31 with solder paste, the welder can intuitively judge whether the flash 43 is placed in place when pressing down the flash 43 with tweezers 42.

[0032] Furthermore, the handle 10 and the positioning portion 30 are made of stainless steel, which prevents the handle 10 and the positioning portion 30 from being corroded in adverse environments, thereby extending the service life of the clamp.

[0033] Also, see Figure 1 The handle 10 includes a connecting member 11 and a grip plate 12. The grip plate 12 is connected to the positioning portion 30 through the connecting member 11. The grip plate 12 is designed according to the gripping posture of human hands to avoid discomfort in the hands when the clamp is used for a long time. The width of the connecting member 11 is smaller than the width of the grip plate 12, thereby reducing the material used to make the connecting member 11 and further reducing the production cost.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
