Abstract
Description
Technical Field
[0001] This utility model relates to the field of plating equipment technology, and in particular to vertical ultrasonic plating equipment. Background Technology
[0002] Currently, in the field of metal surface treatment, hot-dip tin plating is widely used in industries such as electronic components, hardware, and food packaging to improve the solderability, corrosion resistance, and appearance quality of products. Traditional hot-dip tin plating typically includes pretreatment (such as degreasing and pickling), flux coating, hot-dip tin plating, and post-treatment steps.
[0003] However, the existing traditional plating process has the following technical problems: the traditional plating process mostly involves pre-coating with flux and then tinning. The acidity not only causes strong pollution, but the tinning process can also cause certain harm to the operators. Furthermore, the flux residue on the workpiece is permanent, which can corrode the workpiece and affect its performance. Summary of the Invention
[0004] The main purpose of this utility model is to overcome the shortcomings of the existing technology and provide a vertical ultrasonic plating equipment.
[0005] The technical solution adopted by this utility model to achieve its technical purpose is: a vertical ultrasonic tinning device, including an ultrasonic transmitter, an ultrasonic amplitude transformer, an ultrasonic transducer and a tin furnace.
[0006] The ultrasonic transducer generates ultrasonic vibrations that are transmitted to the ultrasonic amplitude transformer, which then transmits the ultrasonic vibrations to the ultrasonic transmitter. The ultrasonic transmitter is located inside the tin furnace and is in direct contact with the molten tin, causing the molten tin to produce a cavitation effect.
[0007] Preferably, a heating plate is fixedly fitted on the outside of the tin furnace, and the ceramic heating plate is wrapped with heat-insulating cotton; wherein, the heating plate is a ceramic heating plate, which helps the tin in the tin furnace to melt; the heat-insulating cotton is aluminum silicate heat-insulating cotton, which mainly serves to insulate the temperature and to a certain extent prevent the temperature from being conducted to the transducer.
[0008] Preferably, the ultrasonic transmitter, ultrasonic amplitude transformer, ultrasonic transducer, and solder pot are all encased in a stainless steel shell. The stainless steel shell encloses the ultrasonic transmitter, ultrasonic amplitude transformer, ultrasonic transducer heating plate, insulation cotton, and solder pot, making the equipment integrated and easy to operate.
[0009] Preferably, it also includes a splash shield assembly, which includes an annular groove plate. Multiple shields are uniformly fixedly installed on the inner ring of the annular groove plate. The shields are made of wear-resistant fabrics such as sunshade cloth. When unfolded, they have an overall fan-shaped structure and can be folded for storage.
[0010] The annular groove plate has rectangular placement slots evenly distributed inside, corresponding to the number of shields. A gear rod is rotatably installed inside the placement slot. One end of the gear rod is extended, and its outer wall is threadedly connected to a bent rod frame. One end of the rod frame is slidably locked inside the rectangular placement slot by a fixed limiting plate, and the other end extends into the inner ring of the annular groove plate and is fixed to one end of the shield.
[0011] The gear rod is installed in the placement slot through a shaft seat. The simultaneous rotation of multiple gear rods can drive multiple rods and limiting plates to move simultaneously in the rectangular placement slot. One end of the rod passes through the placement slot and extends into the inner ring of the annular groove plate to be fixed to the shield. The other end of the shield is fixed to the inner side wall of the annular groove plate, so that the shield can be unfolded or retracted when the rod moves in extension and retraction.
[0012] Preferably, a drive ring plate is rotatably connected inside the annular groove plate, and a protruding annular toothed strip is integrally provided on the inner side of the drive ring plate, which meshes with the gear end of the gear rod.
[0013] The drive ring plate rotates to drive multiple gear rods to rotate simultaneously. One side of the gear end of each gear rod is exposed outside the placement groove, which facilitates its cooperation with the annular toothed strip of the drive ring plate.
[0014] Compared with the prior art, the beneficial effects of this utility model are:
[0015] This vertical ultrasonic soldering equipment uses ultrasonic waves to create cavitation in molten solder, breaking down and removing the oxide layer on the metal surface. This allows the solder to adhere more firmly and evenly to the metal surface, forming a corrosion-resistant solder layer. The entire process does not use flux, avoiding the generation of harmful gases and wastewater pollution, making it environmentally friendly. Furthermore, because no flux is used, no micropores or air bubbles are generated inside the solder joint, resulting in higher solder quality. It also simplifies the soldering process, improves production efficiency, and reduces production costs.
[0016] This vertical ultrasonic plating equipment, through the setting of anti-splash components, can avoid the molten solder being exposed to the air due to the open design of the traditional heating tank, and solves the problem that high-frequency vibration can easily cause molten solder to splash, affecting the welding quality.

However, it should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit its scope. Furthermore, descriptions of well-known structures and technologies are omitted in the following description to avoid unnecessarily obscuring the concept of the present utility model.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. "Several" means one or more, unless otherwise explicitly specified.
[0028] In the description of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances. Example 1
[0029] Please see Figure 1 The vertical ultrasonic tinning equipment includes an ultrasonic transmitter 1, an ultrasonic amplitude transformer 2, an ultrasonic transducer 3, and a tin furnace 6.
[0030] A heating plate 4 is fixedly fitted on the outside of the tin furnace 6, and the ceramic heating plate 4 is wrapped with heat insulation cotton 5. The heating plate 4 is a ceramic heating plate, which helps the tin in the tin furnace 6 to melt. The heat insulation cotton 5 is aluminum silicate heat insulation cotton, which mainly insulates the temperature and prevents the temperature from being conducted to the transducer to a certain extent.
[0031] The ultrasonic transducer 3 generates ultrasonic vibrations that are transmitted to the ultrasonic amplitude transformer 2, and then the ultrasonic amplitude transformer 2 transmits the ultrasonic vibrations to the ultrasonic transmitter 1. The ultrasonic transmitter 1 is located inside the tin furnace 6 and is in direct contact with the molten tin, causing the molten tin to produce a cavitation effect.
[0032] Furthermore, in this embodiment, the ultrasonic transmitter 1, ultrasonic amplitude transformer 2, ultrasonic transducer 3, and solder pot 6 are all externally encased in a stainless steel shell 7. Even further, the stainless steel shell 7 completely encloses the ultrasonic transmitter 1, ultrasonic amplitude transformer 2, ultrasonic transducer 3, heating plate 4, insulation cotton 5, and solder pot 6, making the equipment integrated and easy to operate. Example 2
[0033] Please see Figures 2-6 Based on the above embodiments, the vertical ultrasonic plating equipment also includes an anti-splashing component. The anti-splashing component includes an annular groove plate 9. The bottom of the annular groove plate 9 is fixed to the top of the plating furnace 6. Multiple shields 906 are evenly fixedly installed on the inner ring of the annular groove plate 9. The shields 906 are made of wear-resistant fabrics such as sunshade cloth. When unfolded, they have an overall fan-shaped structure and can be folded for storage.
[0034] It should be noted that when multiple shields 906 are deployed simultaneously, they can form a structure similar to a torus, which can shield the solder pot 6. An observation port is provided in the center of the torus structure for easy observation of the interior of the solder pot 6. Furthermore, since the shields 906 are made of cloth, gaps may inevitably exist between the multiple shields 906 in actual use, but this does not affect the overall anti-splashing effect on the solder pot 6.
[0035] The annular groove plate 9 has rectangular placement slots 901 evenly distributed inside, corresponding to the number of shields 906. A gear rod 903 is rotatably installed inside the placement slot 901. One end of the gear rod 903 is extended, and its outer wall is threadedly connected to a bent rod 904. One end of the rod 904 is slidably locked inside the rectangular placement slot 901 by a fixedly fitted limiting plate 905, and the other end extends into the inner ring of the annular groove plate 9 and is fixed to one end of the shield 906.
[0036] The gear rod 903 is installed in the placement groove 901 through the bearing 902. The simultaneous rotation of multiple gear rods 903 can drive multiple rods 904 and limiting plates 905 to move simultaneously in the rectangular placement groove 901. One end of the rod 904 passes through the placement groove and extends into the inner ring of the annular groove plate 9 to be fixed to the plastic rod at one end of the shield 906. The other end of the shield 906 is directly fixed to the inner ring side wall of the annular groove plate 9. Thus, when the rod moves in extension and retraction, it can drive the shield 906 to unfold or retract.
[0037] A drive ring plate 8 is rotatably connected inside the annular groove plate 9. A protruding annular toothed strip 801 is integrally formed on the inner side of the drive ring plate 8, and the annular toothed strip 801 meshes with the gear end of the gear rod 903. Rotating the drive ring plate 8 drives multiple gear rods 903 to rotate simultaneously. One side of the gear end of each gear rod 903 is exposed outside the placement groove 901, facilitating its engagement with the annular toothed strip 801 of the drive ring plate 8.
[0038] Specifically, in use, when the opening of the tin furnace 6 needs to be covered, the drive ring plate 8 is rotated to drive multiple gear rods 903 to rotate simultaneously. The simultaneous rotation of multiple gear rods 903 can drive multiple rods 904 and limiting plates 905 to move simultaneously within the rectangular placement slot 901. When the rods 904 extend and retract, they can drive the cover 906 to unfold or retract.
[0039] The solution in this embodiment can be selectively combined with solutions in other embodiments.
[0040] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural, procedural, or functional transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of protection of this utility model patent.
