Description

Technical Field

[0001] The utility model relates to the technical field of jigs, in particular to a flip welding jig. Background Art

[0002] With the rapid development of electronic products, the density of components and the complexity of soldering on printed circuit boards (PCBs) are increasing. Although traditional wave soldering equipment can meet the soldering needs of most components, it is difficult for wave soldering equipment to achieve ideal soldering results for some special soldering components, such as components with small size, position offset or complex structure. These components are prone to problems such as poor soldering and incomplete solder joints during the wave soldering process, affecting the overall quality and performance of the product.

[0003] In order to ensure the welding quality of these special components, subsequent manual welding is usually required. However, manual operation has obvious limitations when facing small and complex components. It is not only inefficient, but also difficult to ensure the welding effect. Especially in large-scale production, manual welding cannot meet the production requirements of high efficiency and high quality. Therefore, improving welding efficiency and quality has become a key issue that needs to be solved in the electronics manufacturing industry.

[0004] In response to this demand, a flip soldering jig came into being. This jig can replace manual operation and is specifically used for components that wave soldering equipment cannot meet the soldering requirements. By flipping the soldering jig, efficient and high-quality soldering of specific components can be achieved, thereby significantly improving production capacity, optimizing soldering effects, and ensuring product quality. The emergence of this innovative device has solved the soldering problem for the electronics manufacturing industry and provided reliable technical support. Utility Model Content

[0038] The present application proposes a flip welding jig, which is specifically as follows:

[0039] If you need to explain, please refer to Figure 1 , the device of the present application is introduced with one side where the front hook 3 is set as the front end and the other side as the rear end.

[0040] For reference Figure 1-2 The present application mainly consists of a stabilizing component 1 that plays a bottom supporting role, a soldering table 2 located on the upper side of the stabilizing component 1, a front hook 3 for connecting the stabilizing component 1 and the soldering table 2, a limiting component 4 located on the upper side of the soldering table, and a fixing block 5 that plays a connecting role. The present application device is mainly aimed at some soldering components on PCB boards that cannot meet the soldering requirements on wave soldering equipment and require post-processing soldering to complete the product soldering work; it can meet the drawbacks that (single) manual labor cannot complete, or even if the relevant actions are completed, the soldering effect and soldering efficiency are affected. Thereby achieving the advantages of excellent soldering effect and improved production capacity.

[0041] For reference Figure 1 In the present application, the bottom support is performed by a stabilizing component 1, wherein the stabilizing component 1 comprises a bottom plate 11, a support column 12 and a rotating shaft block 13; the bottom plate 11 is used for bottom support; four support columns 12 are provided, which are rectangularly distributed on the upper surface of the bottom plate 11; two rotating shaft blocks 13 are provided, which are symmetrically arranged on both sides of the upper surface of the bottom plate 11.

[0042] For reference Figure 1-2 , wherein the stabilizing assembly 1 is used to support the welding table 2, wherein the welding table 2 includes a welding plate 21, a front axle 22 and a rear axle 23; the welding plate 21 is parallel to the upper side of the bottom plate 11, and the front edge does not exceed the two support columns 12 at the front end of the bottom plate 11, and the rear lower surface thereof contacts the upper surface of the two support columns 12 at the rear end of the bottom plate 11; there are two front axles 22, which are symmetrically arranged on the front side of the upper surface of the welding plate 21, and are connected to the upper side of the surface of the rotating shaft block 13 through a rotating shaft; there are two rear axles 23, which are symmetrically arranged on the rear side of the upper surface of the welding plate 21, and are connected to the fixed block 5 through a rotating shaft. When the fixed block 5 is not connected to the limiting assembly 4, the welding table 2 can be driven to rotate together with the limiting assembly 4 as a whole, and due to the position setting of the support columns 12, after the rotation, the two support columns 12 located on the front side will play a supporting role, and because there is a distance between the support columns 12 on the front side and the front edge of the welding table 2 before the rotation, it will not affect the rotation process.

[0043] For reference Figure 1-2A limiting component 4 is arranged on the top of the welding table 2, and the rear end of the limiting component 4 is connected to the fixing block 5 by bolts, while the front end of the limiting component 4 is not connected to the structure of the welding table 2. When the front end of the limiting component 4 is horizontal, the support is located on the upper side of the front axle 22, and the front axle 22 keeps the surface of the limiting component 4 horizontal. At the same time, since the front side of the limiting component 4 has no connection relationship, the opening of the front side will be unstable. Therefore, a front hook 3 is arranged in the middle part of the front end of the limiting component 4 by a hinge, and the bottom of the front hook 3 is clamped on the lower surface of the welding plate 21 in the welding table 2.

[0044] For reference Figure 1-3 The limiting assembly 4 includes a connecting plate 41, a pressure plate fixing bayonet 42, a limiting block 43, an upper pressure plate 44, a lower pressure plate 45 and a positioning pressure block 46; the middle of the edge of one side of the upper surface of the connecting plate 41 is connected to the front hook 3 through a hinge, and there are two pressure plate fixing bayonet 42, which are symmetrically arranged on the side of the connecting plate 41 close to the front hook 3; there are two limiting blocks 43, which are symmetrically arranged on the side of the connecting plate 41 away from the pressure plate fixing bayonet 42, and the upper pressure plate 44 is located on the upper surface of the connecting plate 41, and is fixed with the limiting block 43 through the pressure plate fixing bayonet 42. The lower pressure plate 45 is arranged on the lower surface of the connecting plate 41. The structural design of the upper and lower pressure plates realizes multi-directional clamping of the workpiece, so that the workpiece can be effectively fixed in all directions, and the reliability of clamping is enhanced; the top of the positioning block 46 passes through the lower pressure plate 45 and is connected with the lower surface of the upper pressure plate 44, ensuring that the position of the workpiece is accurate during clamping, thereby improving the repeatability and consistency of the processing, and ensuring that each processing can meet the same high-precision requirements; the cooperation between the various structures can firmly fix the workpiece to prevent movement or loosening during the processing process.

[0045] For reference Figure 1-3 The two pressure plate fixing snap-ons 42 on the front side are used to clamp the front end of the upper pressure plate 44, and the two limit blocks 43 on the rear side are used to reduce the tilting of the rear end of the upper pressure plate 44 to increase stability. The surface of the connecting plate 41 is provided with a plurality of vertical bearings 47 for guiding the upper pressure plate 44, so as to increase stability when setting the upper pressure plate 44. Secondly, a lower pressure bearing 48 is fixedly connected to the bottom of the upper pressure plate 44, and the bottom of the lower pressure bearing 48 passes through the connecting plate 41 and the lower pressure plate 45 in turn, and the bottom of the lower pressure bearing 48 is exposed on the lower surface of the lower pressure plate 45. The overall stable and precise clamping can reduce the repositioning and adjustment time caused by the movement or loosening of the workpiece during the processing, thereby improving the overall processing efficiency.

[0046] In the utility model, the working steps of the device are as follows:

[0047] 1. First, place the welding product on the welding plate 21 and adjust the limit assembly 4 to stabilize the clamping;

[0048] 2. Secondly, if a single rotation limit assembly 4 is required, the front hook 3 can be disassembled to contact the two connections with the welding plate 21;

[0049] 3. Then, if the welding plate 21 needs to be turned over, the connection between the limit assembly 4 and the fixing block 5 can be removed first, and then the welding plate 21 can be rotated to support the welding plate 21 tightly against the support column 12 on the other side;

[0050] 4. Finally, make specific adjustments according to the actual usage.

[0051] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited to the above embodiments. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of protection claimed by the utility model.
