Detailed Implementation

[0017] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. The present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this utility model can be combined with each other.

[0018] It should be noted that the terms "first," "second," etc., in the specification, claims, and drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence.

[0019] This utility model provides a welding fixture 100 for welding electronic devices, specifically for welding electrical components to a substrate. It should be noted that in this utility model, the descriptions of orientation and direction apply only to the welding fixture 100 in its normal operating state, wherein the vertical direction is approximately parallel to the direction of gravity, and the horizontal and vertical directions are perpendicular to the vertical direction and mutually perpendicular.

[0020] Please see Figures 1 to 5 This embodiment provides a welding fixture 100, including a base 10 and a clamping mechanism 20. The upper side of the base 10 is provided with a mounting position 11 for placing a substrate. Guide members 12 are respectively provided on both sides of the base 10 in the transverse direction. The two guide members 12 extend longitudinally and are arranged side by side.

[0021] A clamping mechanism 20 is mounted on the base 10 for pre-fixing electrical components. Specifically, the clamping mechanism 20 includes a sliding frame 21 and multiple clamps 22, which are used to fix the electrical components. The shape and size of the clamps 22 are not limited and can be designed according to the specifications of the electrical components. It can be understood that small electrical components can be clamped using a single clamp 22, while large electrical components can be clamped using multiple clamps 22.

[0022] The sliding frame 21 extends laterally and can have various shapes. In this embodiment, the sliding frame 21 is a cylindrical tube extending laterally. Guide fittings 23 are provided at both ends of the sliding frame 21. These guide fittings 23 correspond one-to-one with the guides 12 on the base 10, allowing the sliding frame 21 to be slidably mounted on the base 10 in a longitudinal direction, adjusting to a suitable position according to the installation requirements of electrical components. Multiple clamps 22 are provided on the sliding frame 21, which are slidably and adjustablely mounted laterally to fix it at different positions in the lateral direction.

[0023] The welding fixture 100 provided in this embodiment can quickly and accurately adjust the position of the clamp 22 according to the specific positional requirements of the electrical components, thereby achieving effective fixation and precise welding of electrical components with special coordinates. The welding fixture 100 can adapt to electronic devices of different sizes and specifications, improving the versatility and flexibility of the welding fixture 100.

[0024] Based on the previous embodiment, the guide member 12 can have various specific shapes. For details, please refer to the relevant documentation. Figure 1 , Figure 2 and Figure 4Each of the guide members 12 includes a longitudinally extending guide rail 121, which protrudes from the upper side of the base 10 and has an upward-opening guide groove 122. Each of the guide mating members 23 includes a pulley 231 and a first limiting structure 232. Each pulley 231 is rotatably mounted in each of the guide grooves 122. The first limiting structure 232 acts on the corresponding guide rail 121 to limit the relative movement between the pulley 231 and the guide rail 121, thereby ensuring the stability of the sliding frame 21 after it slides into place. In this embodiment, the sliding of the sliding frame 21 is achieved by the cooperation of the pulley 231 and the guide groove, which is easy to operate and provides lateral limitation for the sliding frame 21.

[0025] For details, please continue reading Figure 2 Each of the first limiting structures 232 includes a stop 2321 and a first adjusting bolt 2322. The stop 2321 is disposed on the side of the pulley 231 near the mounting position 11 and is attached to the inner side of the corresponding guide rail 121. The sliding frame 21 has screw holes on its two end faces in the lateral direction. The first adjusting bolt 2322 is screwed into the corresponding screw holes and is disposed on the outer side of the corresponding guide rail 121 to abut against the guide rail 121. In this embodiment, when the sliding frame 21 needs to slide, the first adjusting bolt 2322 can be loosened. When it slides to the desired position, the first bolt can be tightened, so that the guide rail 121 is partially clamped between the first bolt and the stop, thereby achieving reliable positioning of the first sliding frame 21.

[0026] There are various ways to fix each clamp 22 to the sliding frame 21. In this embodiment, please refer to... Figures 1 to 3 The welding fixture 100 also includes multiple mounting components 30. Each clamp 22 is movably and adjustablely mounted to the sliding frame 21 via each mounting component 30. Each mounting component 30 includes a mounting block 31 with a through hole extending laterally, and a second limiting structure 32 disposed on the mounting block 31. The sliding frame 21 passes through the through hole. Each clamp 22 is disposed below each mounting block 31. The second limiting structure 32 acts on the sliding frame 21 to limit the relative movement between the mounting block 31 and the sliding frame 21. In this embodiment, when the position of the clamp 22 needs to be adjusted, the second limiting structure 32 can be operated first to move the mounting block 31, allowing it to slide laterally to the desired position, and then it can be fixed. This simplifies operation and improves welding efficiency.

[0027] Furthermore, each mounting block 31 has a screw hole on at least one end face in the longitudinal direction, and the second limiting structure 32 includes a second limiting bolt passing through each screw hole. The second limiting bolt is used to abut against the sliding frame 21. Preferably, each mounting block 31 has a screw hole on each of its two end faces in the longitudinal direction, and the second limiting structure 32 includes two second limiting bolts, which are respectively disposed on both sides of the sliding frame 21 in the longitudinal direction. In this way, the clamp 22 can be limited by the cooperation of the two limiting bolts. It can be understood that the through hole on the mounting block 31 is preferably slightly larger in the longitudinal direction than the sliding frame 21. Thus, by adjusting the tightening degree of the two second limiting bolts, the position of the clamp 22 in the longitudinal direction can also be finely adjusted, making the positioning of the clamp 22 more accurate and improving the clamping accuracy.

[0028] Based on the above embodiment, multiple sliding frames 21 are provided, and the multiple sliding frames 21 are arranged side by side in the longitudinal direction. In this way, the welding fixture 100 can simultaneously clamp and fix more electrical components, thereby improving welding efficiency.

[0029] Optionally, a mounting base 40 is provided on the upper side of the base 10. The mounting base 40 is detachably mounted on the upper side of the base 10 and inserted between the two guide members 12. The upper surface of the mounting base 40 is recessed with a mounting groove 41, which constitutes the mounting position 11. In this way, the substrate is fixed by the mounting groove 41, which is simple and reliable. Moreover, the mounting base 40 can be replaced with a suitable one according to the actual specifications of the substrate, further enhancing the versatility of the welding fixture 100.

[0030] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, those skilled in the art can make other variations or modifications without creative effort, and all such variations or modifications should fall within the protection scope of this utility model.
