[0039] Please refer to the attached document. Figures 1-5 This application provides a welding fixture 100, which is used to support the circuit board to be welded, ensuring that the pins of the circuit board to be welded are exposed.

[0040] Please refer to the attached document. Figures 1-5 In this embodiment, the welding fixture 100 includes a support base 10, a cover plate assembly 20, and a locking member 30. The support base 10 is provided with a receiving groove 10a and a plurality of clearance holes 10b. The receiving groove 10a is used to receive a circuit board. The plurality of clearance holes 10b are all connected to the same receiving groove 10a and exposed to the pins of the circuit board to be welded. The cover plate assembly 20 includes a cover plate 21 and a plurality of elastic pressing members 22. The cover plate 21 is rotatably connected to the support base 10. The plurality of elastic pressing members 22 are all connected to the same cover plate 21, and the plurality of elastic pressing members 22 that are far from the cover plate 21 are... One end serves as an elastic pressing end, elastically pressing against the circuit board located in the receiving groove 10a; multiple elastic pressing members 22 elastically press against different positions of the circuit board respectively; the engaging member 30 is swayably connected to the support base 10 and engages the cover plate 21 to maintain the state of the cover plate 21. By applying elastic force to multiple different positions of the circuit board through multiple elastic pressing members 22, it avoids engaging only one position of the circuit board, ensuring the stability of the circuit board relative to the support base 10, improving the stability of the circuit board of the welding fixture 100, and at the same time, improving the welding effect of the circuit board.

[0041] Please refer to the attached document. Figures 1-5 In this embodiment of the application, the support base 10 serves as a support component of the welding fixture 100, and the support base 10 is used to support the circuit board, the cover plate assembly 20 and the snap-fit ​​component 30.

[0042] The support base 10 is provided with a receiving groove 10a and a plurality of clearance holes 10b; the receiving groove 10a serves as the internal space of the support base 10 and is used to accommodate the circuit board so that the circuit board can be stored inside the support base 10 through the receiving groove 10a; the plurality of clearance holes 10b are provided on the lower side of the receiving groove 10a, and the plurality of clearance holes 10b are all connected to the same receiving groove 10a and exposed to the pins of the circuit board to be soldered so that the pins of the circuit board to be soldered can extend to the external environment through the plurality of clearance holes 10b.

[0043] The cover plate assembly 20 includes a cover plate 21 and multiple elastic pressing members 22. The cover plate 21 is disposed on the upper side of the support base 10 and is rotatably connected to the support base 10. The cover plate 21 is rotatable along the axial direction of the connection between the cover plate 21 and the support base 10 to facilitate adjustment of the position of the cover plate 21 relative to the support base 10. The multiple elastic pressing members 22 are all connected to the same cover plate 21. One end of the multiple elastic pressing members 22 away from the cover plate 21 serves as the elastic pressing end and elastically presses against the circuit board in the receiving groove 10a. The multiple elastic pressing members 22 elastically press against different positions of the circuit board. By applying elastic force to multiple different positions of the circuit board through the multiple elastic pressing members 22, the circuit board is prevented from being locked in only one position, ensuring the stability of the circuit board relative to the support base 10, improving the stability of the circuit board of the welding fixture 100, and improving the welding effect of the circuit board. Optionally, the cover plate 21 can swing relative to the support base 10 via a hinge.

[0044] The engaging member 30 is located between the support base 10 and the cover plate 21. The engaging member 30 is swayably connected to the support base 10. The engaging member 30 swings along the axial direction of the connection between the engaging member 30 and the support base 10 to adjust the position of the engaging member 30 relative to the support base 10. The engaging member 30 engages the cover plate 21 to maintain the state of the cover plate 21, ensuring that the position of the cover plate 21 relative to the support base 10 remains unchanged, thus improving the stability of the cover plate 21.

[0045] Please refer to the attached document. Figure 1 In this embodiment of the application, when the circuit board needs to be soldered, the surface of the cover plate 21 contacts the outer platform, and multiple elastic pressing members 22 apply an upward elastic force so that the elastic force of the multiple elastic pressing members 22 abuts against the circuit board, preventing the circuit board from being partially recessed. The pins of the circuit board to be soldered face upward and are exposed to the clearance hole 10b, which improves the soldering effect of the circuit board.

[0046] Please refer to the attached document. Figures 3-5In this embodiment, the elastic pressing member 22 includes a mounting post 221 and a pressing head 222. The mounting post 221 is arranged vertically and mounted on the cover plate 21 so that the elastic pressing member 22 can be connected to the cover plate 21 through the mounting post 221. The pressing head 222 is movably connected to the mounting post 221 and moves elastically relative to the mounting post 221 so as to adjust the position of the pressing head 222 relative to the mounting post 221. The pressing head 222 applies an elastic force to the circuit board so that the elastic pressing member 22 can apply an elastic force to the circuit board through the pressing head 222. By applying an elastic force to multiple different positions of the circuit board through multiple elastic pressing members 22, it is avoided that only one position of the circuit board is locked, thus ensuring the stability of the circuit board relative to the support base 10 and improving the stability of the circuit board of the welding fixture 100.

[0047] Please refer to the attached document. Figures 1-5 In this embodiment, the elastic pressing member 22 is mounted on the cover plate 21 and arranged relative to the clearance hole 10b; this facilitates the arrangement of the elastic pressing member 22 relative to the soldering pins of the circuit board, ensuring that the soldering pins of the circuit board are exposed to the clearance hole 10b. The elastic pressing member 22 also includes an elastic member 223, which passes through the mounting post 221. Both ends of the elastic member 223 elastically contact the cover plate 21 and the pressing head 222, respectively, to apply an elastic force to the pressing head 222, so that the pressing head 222 can apply an elastic force to the circuit board through the force of the elastic member 223. Optionally, the elastic member 223 is a spring; the pressing head 222 is a plastic part.

[0048] Please refer to the attached document. Figures 1-4 In this embodiment, the support base 10 is provided with a T-shaped boss 11; the engaging member 30 includes a main body 31 and an engaging part 32; the main body 31 is swayably connected to the T-shaped boss 11 and swings relative to the T-shaped boss 11 to adjust the position of the main body 31 relative to the T-shaped boss 11; the engaging part 32 is connected to the main body 31 and engages with the cover plate 21 as the main body 31 swings; the engaging part 32 and the T-shaped boss 11 are clamped in the cover plate 21 so that the engaging member 30 can engage the cover plate 21 through the engagement part 32 and the T-shaped boss 11, thereby facilitating the engagement part 32 and the T-shaped boss 11 to restrict the cover plate 21 from moving in the vertical direction; when the engaging part 32 disengages from the cover plate 21 under the action of external force, the cover plate 21 can swing relative to the support base 10. Optionally, the main body 31 swings relative to the T-shaped boss 11 through a rotating shaft.

[0049] Please refer to the attached document. Figures 1-4In this embodiment of the application, the T-shaped boss 11 is provided with a receiving groove 11a. Part of the main body 31 is received in the receiving groove 11a during the swinging process, so that the part of the main body 31 can make full use of the space of the receiving groove 11a. This allows the T-shaped boss 11 to avoid the part of the main body 31 through the receiving groove 11a, preventing the T-shaped boss 11 from interfering with the main body 31 and ensuring the swinging effect of the main body 31.

[0050] Please refer to the attached document. Figure 4 In this embodiment, the T-shaped boss 11 is detachably connected to the support base 10 and can be connected to or disconnected from the support base 10, which improves the ease of installation and removal of the T-shaped boss 11.

[0051] Please refer to the attached document. Figure 1 In this embodiment of the application, the welding fixture 100 also includes a plurality of feet 40, which are connected to the support base 10 and distributed at the corners of the support base 10, so that the support base 10 can increase the distance between itself and the external table surface by means of the plurality of feet 40. At the same time, the stability of the support base 10 relative to the external table surface is increased by arranging the plurality of feet 40.

[0052] Please refer to the attached document. Figure 1 In this embodiment of the application, a plurality of feet 40 and support base 10 form a relief groove 40a. The relief groove 40a is connected to the relief hole 10b and prevents the pin from contacting the platform. The space of the relief groove 40a prevents the pin from contacting the platform, avoids interference between the platform and the pin, and ensures the positional accuracy of the pin.
