[0020] The technical solution of the present invention will be further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0021] A tinning device for inductor production includes a tinning tank 1, with a liquid inlet pipe 2 and a liquid outlet pipe 3 provided at the upper and lower ends of the side walls of the tinning tank 1, respectively. A storage cavity 4 with a semicircular vertical cross-section is provided at the bottom of the tinning tank 1. A stirring mechanism 5 is provided in the storage cavity 4, one end of which extends above the storage cavity 4 into the tinning tank 1. A tinning mechanism 6 driven by the stirring mechanism 5 is provided at the top of the tinning tank 1.

[0022] The stirring mechanism 5 includes a rotating shaft 51 driven by a motor and located in the storage chamber 4, one end of the rotating shaft 51 extends into the cylinder 52 outside the tin immersion box 1, and a fan blade 53 is provided at the end of the rotating shaft 51 in the cylinder 52. Air holes 54 are evenly provided on the outer wall of the rotating shaft 51 in the cylinder 52, and an air channel 55 connected to the air hole 54 is also axially provided in the side wall of the rotating shaft 51. A one-way air outlet pipe 56 connected to the air channel 55 is evenly provided on the outer wall of the rotating shaft 51 in the storage chamber 4, and multiple groups of rectangular hole plates I57 are also axially provided on the outer wall of the rotating shaft 51 in the storage chamber 4. In this embodiment, the rotating shaft 51 and the storage chamber 4 are coaxially arranged, and one end of the lower rectangular hole plate I57 is set against the side wall of the storage chamber 4.

[0023] The tin dipping mechanism 6 includes a filter frame 61, a strip plate 62 is longitudinally arranged in the middle of the bottom of the filter frame 61, and a support shaft 63 with an end embedded in the side wall of the tin dipping box 1 is also longitudinally arranged in the middle of the top of the filter frame 61. A slot for accommodating the end of the support shaft 63 is provided on the inner wall of the tin dipping box 1, and the side wall of the filter frame 61 is fixedly connected to the support shaft 63. A sleeve 64 is provided on the outer sleeve of the support shaft 63 in the filter frame 61, and a hole-shaped cover plate 65 is provided on both sides of the sleeve 64. An arc-shaped orifice plate 66 is provided in the filter frame 61 below the cover plate 65. The cover plate 65 seals the top opening of the arc-shaped orifice plate 66, and a rectangular orifice plate II67 is radially provided on the outer wall of the bottom of the sleeve 64 to abut against the inner arc wall of the arc-shaped orifice plate 66.

[0024] In this embodiment, the vertical cross-section of the strip plate 62 is an isosceles trapezoidal structure, and the lower bottom end of the strip plate 62 is fixedly connected to the bottom end surface of the filter frame 61. The motor drives the rotating shaft 51 to drive the rectangular orifice plate I57 to rotate counterclockwise until the top of the rectangular orifice plate I57 at the top contacts an inclined end of the strip plate 62.

[0025] like Figure 2 As shown, the outer arc walls at both ends of the arc-shaped orifice plate 66 are fixedly connected to the corresponding inner side walls of the filter frame 61, and one end of the arc-shaped orifice plate 66 is lower than the horizontal plane of the other end. The ends of the two groups of cover plates 65 are both against the inner walls corresponding to the open ends of the arc-shaped orifice plate 66, and the end of one group of cover plates 65 is further provided with a magnetic strip 7 located above the top end of the arc-shaped orifice plate 66, and a handle is provided on the top of the cover plate 65.

[0026] like Figure 2 As shown, a limit rod 8 is installed in the tin immersion box 1 on the right side of the filter frame 61, which is against the outer wall of the filter frame 61. A spring 9 connected to the corresponding inner wall of the tin immersion box 1 is arranged on the outer wall of the filter frame 61 below the limit rod 8 and is tilted upward.

[0027] like Figure 2 、 3 As shown, the one-way air outlet pipe 56 and the rectangular orifice plate 157 are staggered, and the side wall at the edge of the rectangular orifice plate 157 is a solid structure.

[0028] When the inductor is placed in, the cover plate 65 drives the sleeve 64 to rotate clockwise on the support shaft 63, thereby separating the magnetic strip 7 from the top of the left end of the arc-shaped orifice plate 66. At this time, the right cover plate 65 and the rectangular orifice plate II67 rotate clockwise in the opening of the arc-shaped orifice plate 66, and the left cover plate 65 opens the top opening of the left side of the arc-shaped orifice plate 66. When the rectangular orifice plate II67 completely slides out of the opening of the arc-shaped orifice plate 66, part of the inductor can be placed in the top of the cover plate 65 on the left side. Then, the cover plate 65 is rotated counterclockwise to drive the sleeve 64 to support the magnetic strip 7. The shaft 63 rotates counterclockwise, and when a group of rectangular orifice plates II67 slides into the opening of the arc-shaped orifice plate 66, part of the inductance is placed above the rectangular orifice plate II67. Similarly, a number of inductors are evenly distributed above the arc-shaped orifice plates 66 on both sides of the rectangular orifice plate II67. Finally, the two groups of cover plates 65 seal the top opening of the arc-shaped orifice plate 66. At the same time, the left cover plate 65 drives the magnetic strip 7 to move to the top of the left end of the arc-shaped orifice plate 66 and fixes it magnetically, so that the cover plate 65 will not rotate without human intervention, thereby sealing the top opening of the arc-shaped orifice plate 66.

[0029] During the above process, the product is immersed in the tin liquid in the tin immersion box 1. At this time, the motor drives the rectangular orifice plate I57 to rotate in the storage chamber 4 by driving the rotating shaft 51, thereby mechanically stirring the liquid at the bottom of the storage chamber 4 to prevent the liquid from settling. At the same time, the aperture of the side wall of the rectangular orifice plate I57 facilitates the flow of liquid to reduce the resistance encountered when the rectangular orifice plate I57 rotates, and the rotating rotating shaft 51 drives the fan blades 53 to rotate so that negative pressure is generated in the cylinder 52, and then the outside air is drawn into the air channel 55 through the air vent 54, and then enters the storage chamber 4 through the one-way air outlet pipe 56 to pneumatically stir the liquid, so as to further reduce the problem of liquid precipitation in the storage chamber 4.

[0030] When the rotating shaft 51 in the stirring mechanism 5 drives the rectangular orifice plate I57 to rotate counterclockwise, when the rectangular orifice plate I57 rotates to the top of the driving shaft 51, the top of the rectangular orifice plate I57 will contact the inclined surface of one side of the strip plate 62, and then the rectangular orifice plate I57 continues to rotate, then its top will push the strip plate 62 and drive the support shaft 63 through the filter frame 61 to rotate clockwise in the slot in the side wall of the tin immersion box 1. At this time, the rotating filter frame 61 drives the product above the arc orifice plate 66 to rotate clockwise through the arc orifice plate 66, the cover plate 65 and the rectangular orifice plate II67, and the rotating filter frame 61 also pulls the spring 9 to stretch it. Figure 3As shown, when one group of rectangular orifice plates I57 is separated from the strip plate 62, and the other group of rectangular orifice plates I57 downstream has not yet rotated to the position directly above the rotating shaft 51, at this time, under the influence of the loss of the pushing effect of the rectangular orifice plate I57, the contraction of the spring 9 will pull the filter frame 61 to drive the support shaft 63 to rotate counterclockwise in the slot in the side wall of the tin immersion box 1. At this time, the rotating filter frame 61 drives the product above the arc orifice plate 66 to rotate counterclockwise through the arc orifice plate 66, the cover plate 65 and the rectangular orifice plate II67. When the filter frame 61 is reset, the limit rod 8 presses against its right side wall to limit its swing amplitude, and then repeats the above steps. In this way, the products on both sides of the rectangular orifice plate II67 above the arc orifice plate 66 are shaken, so that the products can fully contact with the liquid to improve the tin immersion effect and efficiency.

[0031] When the tin dipping is completed, it is taken out in the opposite way to the above-mentioned product placement, specifically: the cover plate 65 is moved by the handle, so that the sleeve 64 rotating clockwise on the support shaft 63 drives the cover plate 65 and the rectangular hole plate II67 to rotate. At this time, the rotating right cover plate 65 and the rectangular hole plate II67 can push the inductor located in the opening of the arc hole plate 66 to slowly slide out of the tin liquid, and when the rectangular hole plate II67 or the cover plate 65 pushes the product out of the tin liquid, the liquid on the surface of the product can be drained through the aperture of the side wall of the above-mentioned component, so as to facilitate people to take out the processed product. In the above process, part of the liquid in the tin dipping box 1 can be discharged to prevent the rotating cover plate 65 and the rectangular hole plate II67 from pushing the product to slide to the top opening of the arc hole plate 66 and being soaked in liquid.

[0032] The present invention uses a stirring mechanism 5 to simultaneously pneumatically and mechanically stir the liquid in the tin dipping box 1 to prevent the liquid from settling. The rotating stirring mechanism 5 also drives the product in the tin dipping mechanism 6 to shake, so that the product above the arc-shaped orifice plate 66 in the tin dipping mechanism 6 is fully in contact with the liquid to improve its tin dipping effect and efficiency. The rectangular orifice plate II67 in the tin dipping mechanism 6 separates the product in different areas on the top of the arc-shaped orifice plate 66 to prevent a large amount of product accumulation and affect the tin dipping work. At the same time, the movement range of the product can be limited to improve its safety. The cover plate 65 is rotated to drive the sleeve 64 to rotate on the support shaft 63, thereby driving the rectangular orifice plate II67 and the cover plate 65 to rotate above the arc-shaped orifice plate 66 and push the product out of the tin liquid, so as to facilitate people to take out the processed product.

[0033] The present invention has been described in detail above, but the contents described are only preferred embodiments of the present invention and should not be considered to limit the scope of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
