Therefore, it cannot be understood as a limitation on the present invention.
[0030] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.
[0031] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.
[0032] Please refer to Figures 1 to 3 This embodiment provides a welding fixture 10 for welding a metal component 12 to a PCB 11. It should be noted that during the welding process, the welding fixture 10 provides a pressing force on the PCB 11, preventing deformation of the metal component 12. This improves the welding success rate and reduces the welding difficulty, thereby resolving the technical issue of the high difficulty in welding metal components 12 to the PCB 11 in the prior art.
[0033] In this embodiment, the welding tool 10 includes a base 100, a fixing member 200, a clamping plate 300 and a clamping assembly 400. A plurality of first through holes 101 are provided on the base 100; the provision of the plurality of first through holes 101 makes the base 100 as a whole mesh-shaped, which can facilitate the passage of high-temperature airflow through the first through holes 101. The fixing member 200 is provided on the base 100 and is used to fix the PCB board 11. The fixing member 200 can ensure the overall stability of the PCB board 11, thereby improving the welding stability and the success rate. The clamping plate 300 is used to press the metal part 12 onto the PCB board 11; a plurality of second through holes 310 are provided on the clamping plate 300. Similarly, the second through holes 310 are used for allowing high-temperature airflow to pass through, thereby achieving the purpose of improving welding stability and the success rate. The pressing assembly 400 includes a sliding body 410 and a pressing member 420; the sliding body 410 is slidably disposed on the base 100, and the sliding body 410 is located above the pressing plate 300; the pressing member 420 is movably disposed on the sliding body 410, and the pressing member 420 is used to move toward the pressing plate 300 to press the pressing plate 300, and is also used to move away from the pressing plate 300 to loosen the pressing plate 300.
[0034] As described above, when it is necessary to solder the metal part 12 to the PCB board 11, the PCB board 11 can be first fixed to the fixing member 200, and then the fixing member 200 can be placed on the base 100; after the solder is coated on the metal part 12, the metal part 12 is placed at a designated position on the PCB board 11; and then the pressing plate 300 is placed on the metal part 12. By sliding the sliding assembly relative to the base 100, the pressing member 420 in the sliding assembly can be moved to a designated position on the metal part 12, and can be pressed against the pressing plate 300 while moving toward the pressing plate 300, so that the pressing plate 300 presses the metal part 12 on the PCB board 11. Since the base 100 is provided with a first through hole 101 and the pressing plate 300 is provided with a second through hole 310, the pressed metal part 12 and PCB board 11 can be reflowed to achieve the welding of the metal part 12 on the PCB board 11. Among them, since the clamping plate 300 as a whole provides a clamping effect on the metal part 12, it can prevent the metal part 12 from deforming during the welding process, and thus avoid the problem of leakage after welding. Based on this, the difficulty of welding the metal part 12 on the PCB board 11 is reduced, thereby improving the technical problem of the difficulty of welding the metal part 12 on the PCB board 11 in the existing technology.
[0035] It is worth noting that, since the PCB board 11 is clamped by the clamping plate 300 and the fixing member 200 , the welding tool 10 can be adapted to PCB boards 11 of different thicknesses, thereby improving the versatility of the welding tool 10 .
[0036] Optionally, in this embodiment, the PCB board 11 is fixed to the fixing member 200 by screws. Fixing the PCB board 11 by screws not only facilitates assembly and disassembly, but also further improves the installation stability of the PCB board 11 on the fixing member 200 through the self-locking effect of the screws, thereby improving the welding success rate.
[0037] In this embodiment, the base 100 includes a carrier body 110 and two mounting bodies 120. The two mounting bodies 120 are disposed on either side of the carrier body 110, forming a U-shaped cross-section of the base 100. The fixing member 200 is positioned on the carrier body 110 and between the two mounting bodies 120. A first sliding groove 121 extending along a first horizontal direction is defined on the side of the mounting body 120 away from the carrier body 110. The two ends of the sliding body 410 slide in engagement with the two first sliding grooves 121, respectively. The sliding body 410 can slide in the first sliding grooves 121, thereby adjusting the position of the sliding body 410 in the base 100 and facilitating the movement of the pressing member 420 to a desired position, thereby compressing the desired position and preventing damage to the metal member 12. This also facilitates the compression of PCB boards 11 of various widths. The first horizontal direction can be considered the length of the mounting body 120.
[0038] Optionally, both ends of the sliding body 410 are provided with stoppers 411, which are provided outside the mounting body 120, and the width of the stoppers 411 is greater than the width of the first slide groove 121. Due to the wider width of the stoppers 411, the stoppers 411 cannot directly pass through the first slide groove 121, thereby improving the stability of the sliding body 410 sliding in the first slide groove 121.
[0039] It should be understood that in other embodiments, a groove may be provided on the sliding body 410 , and the sliding body 410 may be limited by cooperating with the mounting body 120 , thereby preventing the sliding body 410 from falling out.
[0040] In this embodiment, a mounting cavity 412 is defined in the sliding body 410. The mounting cavity 412 extends through the sliding body 410 from top to bottom, and a pressing member 420 is disposed within the mounting cavity 412. One end of the pressing member 420 passes through the mounting cavity 412 to press the pressing plate 300, while the other end of the pressing member 420 is located outside the top of the mounting cavity 412. This facilitates the operator's manipulation of the pressing member 420, improving operational convenience.
[0041] Optionally, second slots 413 extending along a second horizontal direction are further defined on both sides of the sliding body 410; sliders 421 are provided on both sides of the pressing member 420, engaging with the second slots 413. The engagement of the sliders 421 and the second slots 413 allows the pressing member 420 to slide on the sliding body 410, thereby adjusting the position of the pressing member 420 on the sliding body 410 and facilitating compression of a specific location on the metal member 12. The second horizontal direction can be considered the longitudinal direction of the sliding body 410, i.e., the direction from one mounting body 120 to the other.
[0042] It should be noted that in this embodiment, the first chute 121 is perpendicular to the second chute 413. Based on the sliding fit between the sliding body 410 and the first chute 121, and the sliding fit between the pressing member 420 and the second chute 413, the pressing member 420 can be adjusted to any position above the base 100, thereby being used to press metal parts 12 of any shape.
[0043] Furthermore, a plurality of pressing members 420 spaced apart along the second horizontal direction are provided in the mounting cavity 412. The plurality of pressing members 420 provide a pressing effect on the metal member 12, thereby ensuring the overall stability of the metal member 12 and preventing the metal member 12 from deforming during welding.
[0044] In this embodiment, the pressing member 420 includes a screwing body 422 and a screwing member 423. The screwing body 422 is connected to the sliding body 410 and has a threaded hole extending from top to bottom. The screwing member 423 cooperates with the threaded hole and is used to rotate in the threaded hole to move closer to or away from the pressing plate 300. The screwing member 423 can be moved up and down by screwing, thereby tightening or loosening the pressing plate 300.
[0045] Optionally, a flat pressing head 424 is provided at the end of the pressing member 420 near the pressing plate 300. The pressing head 424 compresses the metal plate by the pressing head 424, thereby preventing damage to the PCB 11. Furthermore, the surface-to-surface contact can be used to improve the stability of the metal plate.
[0046] In addition, in this embodiment, a plurality of pressing assemblies 400 spaced apart along the first horizontal direction are provided on the base 100. Based on this, multiple positions and various positions of the metal member 12 can be pressed, which can improve the pressing efficiency.
[0047] In summary, when it is necessary to solder the metal part 12 to the PCB board 11, the PCB board 11 can be first fixed to the fixing part 200, and then the fixing part 200 can be placed on the base 100; after the solder is coated on the metal part 12, the metal part 12 can be placed at a designated position on the PCB board 11; and then the clamping plate 300 can be placed on the metal part 12. By sliding the sliding assembly relative to the base 100, the clamping part 420 in the sliding assembly can be moved to a designated position on the metal part 12, and can be pressed against the clamping plate 300 while moving toward the clamping plate 300, so that the clamping plate 300 presses the metal part 12 on the PCB board 11. Since the base 100 is provided with a first through hole 101 and the clamping plate 300 is provided with a second through hole 310, the clamped metal part 12 and PCB board 11 can be reflowed to achieve the welding of the metal part 12 on the PCB board 11. Among them, since the clamping plate 300 as a whole provides a clamping effect on the metal part 12, it can prevent the metal part 12 from deforming during the welding process, and thus avoid the problem of leakage after welding. Based on this, the difficulty of welding the metal part 12 on the PCB board 11 is reduced, thereby improving the technical problem of the difficulty of welding the metal part 12 on the PCB board 11 in the existing technology.
[0048] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
