When the flux tank 9 rises, the coil pin can be immersed in the stored flux, and when the tin liquid tank 10 rises, the coil pin can be immersed in the stored tin liquid. The depth of the coil pin immersed in the liquid is controlled by controlling the rising height of the tank body. A scraper 25 is slidably arranged in the tin liquid tank 10. The scraper can be inserted into the tin liquid. Before tinning, the scraper 25 can slide to scrape the film formed on the surface of the tin liquid due to cooling and solidification to one side, ensuring that the pin can contact the fully melted tin liquid and ensure the tinning effect.

[0015] See also Figure 3-Figure 4As an embodiment of the present invention, a slide groove 5 is provided on the side wall of the rotating drum 3, and the cross-section of the slide groove 5 is T-shaped. A slider 6 with a matching shape is slidably arranged in the slide groove 5, and one end of the pressure plate 7 is fixedly arranged on the slider 6. The movement trajectory of the pressure plate 7 can be limited by the cooperation between the slider 6 and the slide groove 5.

In a natural state, the slider 6 is pushed upward by the spring 28, and the pressure plate 7 can be kept away from the hanging rod 4, so that the coil can be installed on the hanging rod 4.

[0016] See also Figure 1-Figure 4 As an embodiment of the present invention, a semicircular limiting ring 11 is fixedly provided on the top of the center rod 2 near the flux tank 9 and the upper side of the tin liquid tank 10.

[0017] See also Figure 6-Figure 7 As an embodiment of the present invention, a mounting groove 15 is provided on the upper surface of the hanging rod 4, and a plurality of mounting shafts 16 are fixedly arranged in the mounting groove 15. A plurality of clamping blocks 17 are hinged on the plurality of mounting shafts 16. A circular arc portion 18 and a limiting portion 19 are respectively provided at both ends of each clamping block 17. The weight of one end of the limiting portion 19 is greater than the weight of one end of the circular arc portion 18.

When the coil moves to the top of the circular arc portion 18, the circular arc portion 18 can be pressed into the mounting groove 15 by the weight of the coil. At the same time, the limiting portion 19 Move out of the mounting groove 15, and the limiting portion 19 moved out of the mounting groove 15 can limit the coil so that the coil 30 is above the arc portion 18 at one end of the front block 17. In addition, since the arc portion 18 has an arc surface, when the coil 30 needs to pass through the arc portion 18, the arc portion 18 can be pressed down through the contact between the coil 30 and the arc surface of the arc portion 18, thereby ensuring that the coil 30 can move arbitrarily on the hanging rod 4. A protrusion 29 is fixedly provided on the outer side of one end of the mounting groove 15, and the protrusion 29 is used to limit the first coil 30 inserted into the hanging rod 4, so that the first coil 30 is above the arc portion 18 in the first block 17.

[0020] Through the personnel in this field, all the electrical components in this case are connected to their corresponding power supplies through wires, and a suitable controller should be selected according to the actual situation to meet the control requirements. The specific connection and control sequence should refer to the following working principle, and the electrical connection between the electrical components is completed in the order of working in sequence. The detailed connection means are well-known technologies in this field. The following mainly introduces the working principle and process, and no longer explains the electrical control.

[0021] The working principle and use process of the present invention are as follows: when in use, the coil 30 is inserted into the hanging rod 4 located in the loading area. When the first coil 30 contacts the protrusion 29, the limiting portion 19 of the first clamping block 17 can be moved out of the installation groove 15. When the inserted second coil 30 contacts the limiting portion 19 of the first clamping block 17, the arc portion 18 at one end of the second clamping block 17 can be pressed down by the second coil 30, so that the limiting portion 19 of the second clamping block 17 can be moved out of the installation groove 15. Similarly, multiple coils 30 are installed on the hanging rod 4. The length position of each coil 30 on the hanging rod 4 can be initially limited by the clamping block 17 to prevent the distance between two adjacent coils 30 from being too close or too far, and to avoid collision between the two coils 30. After the hanging rod 4 in the loading area is filled with coils 30, the motor 13 is started. The rotation angle of the rotating drum 3 can be controlled by controlling the number of rotations of the motor 13. The motor 13 drives the rotating drum 3 to rotate so that the hanging rod 4 moves to the top of the flux tank 9. After the movement is completed, the flux tank 9 can be pushed upward by the electric telescopic rod 27 under the flux tank 9, so that the pin 31 at the bottom of the coil 30 is immersed in the flux. After the immersion is completed, the flux tank 9 is controlled to descend by the electric telescopic rod 27, and the motor 13 is started again to move the coil 30 soaked in the flux to the top of the tin liquid tank 10, and the motor 26 is started to move the scraper 25. The scraper 25 can scrape the film formed on the upper surface of the tin liquid due to cooling to one side, and then the tin liquid tank 10 is pushed upward by the electric telescopic rod 27 under the tin liquid tank 10, so that the pin 31 of the coil 30 is immersed in the molten tin liquid to complete the tinning. After the tinning is completed, the tin liquid tank 10 moves downward, and the pin 31 of the coil 30 is exposed to the air for cooling, and the motor 13 is started again to move the tinned coil 30 to the unloading area to prepare for unloading, such as Figure 7As shown, when unloading, the coil 30 on the hanging rod 4 is removed in sequence from the outside to the inside. Since the arc portion 18 has an arc surface, when the coil 30 contacts the arc surface, the arc portion 18 can be pushed to move downward, ensuring that when the arc portion 18 protrudes out of the mounting groove 15, the coil 30 can also move freely on the hanging rod 4; by setting four hanging rods 4, four workstations can be formed, and the operations between the various workstations do not affect each other, so that loading, soaking flux, tinning, and unloading can be carried out simultaneously, thereby improving work efficiency; in addition, when the pressing plate 7 moves to the bottom of the semicircular limiting ring 11, the pulley 20 first contacts the inclined surface at the end of the semicircular limiting ring 11, and the pulley 20 can be moved to the bottom of the semicircular limiting ring 11 through the inclined surface. When the pulley 20 moves to the bottom of the semicircular limiting ring 11, the pressing plate 7 can be The plate 7 descends, and after the pressure plate 7 descends, the coil 30 can be fixed and limited by the limit strip 21 and the coil straightening rod 8, while ensuring that the pin 31 of the coil 30 is in a vertical state; since the semicircular limit ring 11 is arranged on the upper side close to the flux groove 9 and the tin liquid groove 10, when the pressure plate 7 moves to above the flux groove 9 and the tin liquid groove 10, the pressure plate 7 will be in a descending state, and when the pressure plate 7 moves out of the flux groove 9 and the tin liquid groove 10, the pulley 20 loses the constraint of the semicircular limit ring 11, and the spring 28 can push the slider 6 to rise, so that the pressure plate 7 is away from the hanging rod 4, and the coil 30 can be loaded on the hanging rod 4 or removed. Through this structure, the coil 30 on the hanging rod 4 can be automatically fixed without manual operation.
