Description

Technical Field

[0001] The utility model relates to the technical field of chip inductor processing, in particular to a lead soldering fixture for chip inductors. Background Technique

[0002] The inductors in general electronic circuits are air-core coils or coils with magnetic cores, which can only pass a small current and withstand a low voltage; while chip inductors can be air-core coils or those with magnetic cores, and their main feature is that they are wound with thick wires and can withstand dozens of amperes, hundreds, thousands, and tens of thousands of amperes. Chip inductors are divided into two types: with magnetic shields and without magnetic shields, and are mainly composed of magnetic cores and copper wires, mainly playing the roles of filtering and oscillation in the circuit.

[0003] Soldering is an indispensable part of inductor soldering, and can also be said to be an indispensable part of electronic component soldering. Before soldering the chip inductor onto the PCB board, it is necessary to perform soldering treatment on the leads of the chip inductor to better solder with the PCB board. However, in the prior art, when manually soldering the chip inductor, it is necessary to place the chip inductor on a magnetic adsorption fixture and then perform soldering treatment. After soldering, it is necessary to manually remove a whole row of chip inductors from the fixture, which is rather troublesome. Content of the Utility Model

[0004] In order to overcome the shortcoming of the troublesome operation of manually removing the chip inductor after soldering, the purpose of the utility model is to provide a lead soldering fixture for chip inductors that does not require manual removal of the chip inductor.

[0005] A lead soldering fixture for chip inductors includes a long board, a connecting board, a magnetic board, a pulling block, a right sliding board, a left sliding board, a fixed shaft, a spiral spring, and a scraping plate. The magnetic board is slidably connected to the front side of the long board. The connecting board is fixedly connected to the top of the magnetic board, and the pulling block is fixedly connected to the top of the connecting board. The left sliding board is slidably connected to the left side of the long board, and the right sliding board is slidably connected to the right side of the long board. A fixed shaft is fixedly connected between the left sliding board and the right sliding board. The scraping plate is slidably connected to the fixed shaft, and a spiral spring is fixedly connected between the scraping plate and the right sliding board. A through hole is opened on the right sliding board.

[0006] In a preferred embodiment of the utility model, it further includes a positioning board. The positioning board is fixedly connected to the bottom of the front side of the long board, and at least one small hole is opened on the positioning board.

[0007] In a preferred embodiment of the utility model, it further includes a limiting rod. The limiting rod is fixedly connected to the bottom of the front side of the magnetic board.

[0008] In a preferred embodiment of the utility model, it further includes a covering frame. The covering frame is fixedly connected between the left sliding board and the right sliding board, and a long strip hole is opened in the middle of the covering frame.

[0009] In a preferred embodiment of the present utility model, an L-shaped block is further included, and L-shaped blocks are fixedly connected to both the left and right sides of the bottom of the long plate.

[0010] In a preferred embodiment of the present utility model, a stop block is further included, and stop blocks are fixedly connected to both the left and right sides of the top of the long plate.

[0011] The present utility model has the following advantages: The present utility model moves the patch inductor on the magnetic plate by moving the scraping plate, without manually taking out the patch inductor, improving the processing efficiency of the patch inductor. By setting the limiting rod, the coil of the patch inductor can be prevented from being contaminated with solder during soldering, ensuring the normal subsequent processing of the patch inductor. A shielding cover is also provided to prevent the patch inductor from falling out from the front side of the magnetic plate when the patch inductor moves to the right. Description of the Drawings

Detailed Embodiment

[0017] The present utility model will be specifically described below in conjunction with the drawings.

[0018] A lead tin soldering jig for patch inductors, as Figures 1 - 4As shown in the figure, it includes a long board 1, a connecting board 2, a magnetic board 3, a pulling block 4, a right sliding board 8, a left sliding board 9, a fixed shaft 10, a spiral spring 11 and a scraping board 12. A magnetic board 3 is slidably connected to the front side of the long board 1. A connecting board 2 is fixedly connected to the top of the magnetic board 3. A pulling block 4 is fixedly connected to the top of the connecting board 2. A left sliding board 9 is slidably connected to the left side of the long board 1. A right sliding board 8 is slidably connected to the right side of the long board 1. A fixed shaft 10 is fixedly connected between the left sliding board 9 and the right sliding board 8. A scraping board 12 is slidably connected to the fixed shaft 10. A spiral spring 11 is fixedly connected between the scraping board 12 and the right sliding board 8. The right sliding board 8 is provided with a through hole.

[0019] When performing soldering on the leads of the chip inductor 5, it is necessary to first load the chip inductor 5 into this fixture. Move the left sliding board 9 and the right sliding board 8 upward. The parts between the left sliding board 9 and the right sliding board 8 will also move upward away from the magnetic board 3, thus exposing the magnetic board 3. Place the chip inductor 5 in front of the magnetic board 3. The magnetic board 3 will adsorb the chip inductor 5 on the magnetic board 3 and make the lead end of the chip inductor 5 face downward. Move downward to reset the left sliding board 9 and the right sliding board 8. Then place this fixture on the soldering rack. By moving the pulling block 4 downward, the connecting board 2 and the magnetic board 3 move downward, so that the leads of the chip inductor 5 are exposed from this fixture. Then move this fixture downward to immerse the leads of the chip inductor 5 into the tin bath for soldering. The tin bath is filled with liquid tin. After the leads of the chip inductor 5 are completely in contact with the liquid tin, the soldering operation can be completed. After soldering, move the long board 1 upward. Then, by moving the pulling block 4 upward, the connecting board 2 and the magnetic board 3 move upward. Then pull the scraping board 12 to the right, and the scraping board 12 drives the chip inductor 5 on the magnetic board 3 to move to the right. Finally, the chip inductor 5 slides out from the through hole of the right sliding board 8. When the scraping board 12 moves to the right, the spiral spring 11 is compressed. When the scraping board 12 is released, the spiral spring 11 will return to its original state and make the scraping board 12 move to the left. Thus, the soldering process for the leads of the chip inductor 5 can be completed. When removing the chip inductor 5, there is no need to manually remove the chip inductor 5 by hand, which saves time and effort and improves the processing efficiency of the chip inductor 5.

[0020] As Figure 3 and Figure 4 shown in the figure, it further includes a positioning board 7. The positioning board 7 is fixedly connected to the bottom of the front side of the long board 1. The positioning board 7 is provided with small holes with the same number as the maximum number of chip inductors 5 placed. When performing soldering on the leads of the chip inductor 5, move the chip inductor 5 downward. The chip inductor 5 will contact the positioning board 7 and be blocked by the small holes of the positioning board 7, so that only the leads of the chip inductor 5 are exposed. The positioning board 7 can prevent the chip inductor 5 from moving downward too much, resulting in the coil of the chip inductor 5 coming into contact with the tin and preventing the subsequent processing of the chip inductor 5 from being affected.

[0021] As Figure 3 and Figure 4As shown, it further includes a limiting rod 6, and the limiting rod 6 is fixedly connected to the bottom of the front side of the magnetic plate 3. When it is necessary to fill the patch inductor 5 into this fixture, place the patch inductor 5 between the connecting plate 2 and the limiting rod 6. When taking out the patch inductor 5, move the scraping plate 12 to the right so that the patch inductor 5 moves to the right along the limiting rod 6 and then slides out from the through hole of the right sliding plate 8. The limiting rod 6 can play a limiting role when the patch inductor 5 moves to the right, and can prevent the patch inductor 5 from moving downward when the scraping plate 12 moves to the right and getting stuck in the small hole of the positioning plate 7, ensuring that the patch inductor 5 can normally slide out from the through hole of the right sliding plate 8.

[0022] As Figure 1 and Figure 4 shown, it further includes a covering frame 15, and a covering frame 15 is fixedly connected between the left sliding plate 9 and the right sliding plate 8. A long strip hole is opened in the middle of the covering frame 15. When it is necessary to take out the patch inductor 5 and move the scraping plate 12 to the right, the patch inductor 5 on the left side will move to the right and squeeze the patch inductor 5 on the right side, and then slide out from the through hole of the right sliding plate 8. The covering frame 15 can prevent the mutually squeezed patch inductors 5 from falling off from the front side of the magnetic plate 3, and can also observe the movement of the patch inductor 5 through the long strip hole of the covering frame 15. When the patch inductor 5 is stuck, it can be repaired through the long strip hole of the covering frame 15.

[0023] As Figure 1 and Figure 4 shown, it further includes L-shaped blocks 13. The number of L-shaped blocks 13 is two, and the L-shaped blocks 13 are fixedly connected to both the left and right sides of the bottom of the long plate 1. When this fixture is placed on the soldering rack to solder the patch inductor 5, the L-shaped blocks 13 can prevent the left sliding plate 9 and the right sliding plate 8 from sliding downward, and avoid the left sliding plate 9 and the right sliding plate 8 sliding downward and entering the tin bath.

[0024] As Figure 1 and Figure 4 shown, it further includes stoppers 14. The number of stoppers 14 is two, and the stoppers 14 are fixedly connected to both the left and right sides of the top of the long plate 1. When it is necessary to load the patch inductor 5 into this fixture, after laying the fixture flat, move the left sliding plate 9 and the right sliding plate 8 upward to expose the magnetic plate 3, place the patch inductor 5 on the magnetic plate 3, and finally move the left sliding plate 9 and the right sliding plate 8 back to their original positions to prevent the left sliding plate 9 and the right sliding plate 8 from sliding upward and detaching from the long plate 1, resulting in the inability to use the scraping plate 12 normally and avoiding the reduction of the processing efficiency of the patch inductor 5.
