Description
Technical Field
[0001] This utility model relates to the field of wave soldering nozzle technology, specifically to a wave soldering nozzle mechanism. Background Technology
[0002] In the electronics manufacturing industry, wave soldering, as a highly efficient and stable welding technology, is widely used in the large-scale soldering production of various electronic components and printed circuit boards (PCBs). The wave soldering nozzle mechanism, as one of the core components of wave soldering equipment, precisely controls the flow direction, speed, and shape of the solder to form a stable solder wave that meets the welding process requirements. The nozzle orifice on the nozzle body is the key channel for solder flow; its unobstructed flow directly determines the quality of the solder wave and the welding effect. Existing wave soldering nozzles have always had open nozzles, which exposes many drawbacks. On the one hand, dust, impurities, and other foreign objects from the surrounding environment can easily enter the nozzle body through the nozzle. These dust and foreign objects gradually accumulate inside the nozzle, altering the original size and shape of the nozzle, affecting the normal flow of solder and the formation of the wave peak. This leads to welding defects such as uneven solder distribution, cold solder joints, and missed solder joints, reducing welding quality and affecting the reliability and stability of electronic products. On the other hand, the accumulation of foreign objects and dust can also cause nozzle blockage, preventing solder from flowing smoothly. In severe cases, it can even cause the entire wave soldering process to stop, forcing production interruptions and increasing equipment maintenance costs and production delay losses. Therefore, we propose a new wave soldering nozzle mechanism. Utility Model Content
[0003] The purpose of this invention is to provide a wave soldering nozzle mechanism that solves the problems in the background art.

[0005] Preferably, a connecting shaft is fixedly installed on the inner wall of the hinge seat, and a connecting plate is fixedly installed on the bottom end of the cover plate. A shaft hole is provided on the connecting plate. The connecting plate is movably sleeved on the outer wall of the connecting shaft through the shaft hole. A torsion spring is fixedly connected between the outer wall of the connecting shaft and the inner wall of the shaft hole. By providing the torsion spring, the connecting plate can drive the cover plate to rotate and reset under the reset force of the torsion spring.
[0006] Preferably, the hanging rope is made of silicone rubber, and the top of the cover plate has a groove. By setting the groove, it is easy for personnel to pull the cover plate, thereby facilitating personnel operation.

The limiting plate is engaged with one end of the fastening bolt. By setting the limiting plate, the fastening bolt can be limited and fixed, thereby improving the stability of the fastening bolt.
[0008] Preferably, the limiting plate has a second shaft hole near one end, and the limiting plate is movably sleeved on the outer wall of the fixed shaft through the second shaft hole. A second torsion spring is fixedly connected between the inner wall of the second shaft hole and the outer wall of the fixed shaft.

It is highly practical. Attached Figure Description

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0015] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0016] like Figure 1-5As shown, this utility model provides a technical solution: a wave soldering nozzle mechanism, including a nozzle body 1, an angle adjustment knob 3 connected to the back of the nozzle body 1, a flow adjustment knob 2 connected to the bottom of the nozzle body 1, a liquid inlet pipe 21 and an air inlet pipe 22 connected to one side of the nozzle body 1, a fixing block 4 fixedly installed on the other side of the nozzle body 1, a fastening bolt 5 threadedly connected to a threaded hole at one end of the fixing block 4, a hinge seat 7 fixedly installed near one side of the top of the nozzle body 1, a cover plate 6 hinged to the hinge seat 7, a hanging rope 13 fixedly installed on the outside of the cover plate 6, and a hook 12 fixedly installed on the outer wall of the nozzle body 1 near the top.
[0017] Furthermore, a connecting shaft 9 is fixedly installed on the inner wall of the hinge seat 7, and a connecting plate 8 is fixedly installed on the bottom end of the cover plate 6. A shaft hole 10 is opened on the connecting plate 8. The connecting plate 8 is movably sleeved on the outer wall of the connecting shaft 9 through the shaft hole 10. A torsion spring 11 is fixedly connected between the outer wall of the connecting shaft 9 and the inner wall of the shaft hole 10. Among them, by setting a torsion spring 11, the connecting plate 8 can drive the cover plate 6 to rotate and reset under the reset force of the torsion spring 11.
[0018] Furthermore, the hanging rope 13 is made of silicone rubber, and the top of the cover plate 6 has a groove 14. The groove 14 allows personnel to pull the cover plate 6, making operation easier.
[0019] Furthermore, a fixed shaft 16 is fixedly installed at one end of the fixed block 4, and a limiting plate 15 is movably sleeved near one end of the fixed shaft 16. The limiting plate 15 is snapped into one end of the fastening bolt 5. The limiting plate 15 can be set to limit and fix the fastening bolt 5, thereby improving the stability of the fastening bolt 5.
[0020] Furthermore, a shaft hole 19 is provided near one end of the limiting plate 15. The limiting plate 15 is movably sleeved on the outer wall of the fixed shaft 16 through the shaft hole 19. A torsion spring 20 is fixedly connected between the inner wall of the shaft hole 19 and the outer wall of the fixed shaft 16. In this design, a second torsion spring 20 is provided so that the limiting plate 15 can be reset and rotated under the reset force of the second torsion spring 20.
[0021] Furthermore, a baffle 17 is fixedly installed at one end of the fixed shaft 16, and a baffle 2 18 is slidably connected to the inner side of the limiting plate 15. The baffle 2 18 is fixedly sleeved on the outer wall of the fixed shaft 16. By setting baffle 17 and baffle 2 18, the limiting plate 15 can be limited to ensure the stability of the limiting plate 15 on the fixed shaft 16.
[0022] Specifically, in the above technical solution, when the wave soldering nozzle mechanism is in use, the cover plate 6 is pulled up by the slot 14, causing the cover plate 6 to drive the connecting plate 8 to twist the torsion spring 11, so that the cover plate 6 no longer covers the nozzle body 1. Then, the hanging rope 13 on the cover plate 6 is hung on the hook 12 to fix the cover plate 6. When the nozzle body 1 is not used for a long time, the hanging rope 13 can be removed from the hook 12. At this time, the connecting plate 8 will drive the cover plate 6 to rotate and reset under the reset force of the torsion spring 11, so that the cover plate 6 covers and protects the nozzle body 1, thereby preventing dust or foreign objects from entering the nozzle body 1 and causing blockage of the nozzle, which would affect the nozzle body 1. Normal use of the nozzle body 1 is affected, which may affect the normal welding process and increase the service life of the nozzle. The fixing block 4 is installed in a fixed position by fastening bolts 5. Before tightening the fastening bolts 5, the limiting plate 15 is rotated so that the limiting plate 15 twists the torsion spring 20, so that the limiting plate 15 is not on the side of the threaded hole opened at one end of the fixing block 4. After the fastening bolts 5 are tightened, the limiting plate 15 can be loosened, so that the limiting plate 15 rotates under the reset action of the torsion spring 20 until it is locked into the head of the fastening bolt 5, thereby limiting the fastening bolt 5, thereby improving the stability of the fastening bolt 5 during use, preventing the fastening bolt 5 from loosening due to the vibration generated during welding, and thus improving the stability of the nozzle body 1 during installation and use. It is highly practical.
