A third electrode strip 3b and a fourth electrode strip 3c are symmetrically arranged on the left and right sides of the second welding piece 3a. The third electrode strip 3b and the fourth electrode strip 3c are bent at the edge of the battery 1 and extend in a direction away from the battery 1.

[0058] The magnet 4 is disposed on the upper portion of the first pole piece 2, between the first pole band 2b and the second pole band 2c. The end of the magnet 4 having the north and south pole markings N is placed on the outside.

[0059] The first pole strip 2b, the second pole strip 2c, the third pole strip 3b and the fourth pole strip 3c extend out of the end surface of the heat shrink tube 5, which is convenient for connecting the PCB board.

[0060] A first PCB board 6 is arranged above the magnet 4 , a lens 7 is arranged on the first PCB board 6 , a second PCB board 8 is arranged below the battery 1 , and an antenna 9 is arranged at the lower portion of the second PCB board 8 .

[0061] like Figure 9 、 Figure 10 As shown, in this embodiment, the first PCB board 6 is provided with a first welding point hole 6a, and the second PCB board 8 is provided with a second welding point hole 8a.

[0062] The diameter of the clearance hole 101 is larger than the diameter of the lens 7, and the inner diameter of the positioning flange 202 is larger than the outer diameter of the antenna 9. This is beneficial for the assembly of the lens 7 and the antenna 9.

[0063] One side of the first PCB board 6 is connected to the third PCB board 10 , and the lower cover 200 is provided with a clearance position 203 corresponding to the third PCB board 10 .

[0064] A first paving flange 102 is provided on the upper portion of the upper cover 100 . When the upper cover 100 and the lower cover 200 are buckled together, the outer end of the lens of the capsule core is shorter than the end surface of the first paving flange 102 .

[0066] Under the combined force of the upper cover 100 and the lower cover 200, the assembly height of the capsule core is limited to the height X of the positioning hole 201, the height of the capsule core is ensured, and the capsule shell will not be inconvenient to assemble due to the excessive height of the capsule core, thereby improving production efficiency.

[0067] The above-mentioned magnetic control capsule core assembly tool can be applied to a method for manufacturing a magnetic control capsule core, which includes the following steps:

[0068] 1) Making a battery magnet assembly: making a battery magnet assembly by combining a first pole piece, a magnet, a battery, and a second pole piece;

[0069] In this embodiment, manufacturing the battery magnet assembly includes the following steps:

[0070] 1a) A first pole piece is provided. The first pole piece includes a first welding piece that can be welded to a battery. A first pole strip and a second pole strip are symmetrically provided on left and right sides of the first welding piece.

[0071] A second pole piece is provided, the second pole piece includes a second welding piece that can be welded to the battery, and a third pole band and a fourth pole band are symmetrically arranged on the left and right sides of the second welding piece.

[0072] 1b) If Figure 11 、 Figure 12 As shown, the first pole piece and the second pole piece are welded to the two poles of the battery respectively. The butt welding process is adopted during welding, which does not generate a new height and is conducive to controlling the total length of the capsule.

[0073] 1c) If Figure 13 、 Figure 14 As shown, a magnet is placed above the first pole piece, the first pole strip and the second pole strip are bent along the direction of the magnet, and the third pole strip and the fourth pole strip are bent in a direction away from the battery.

[0074] like Figure 15 、 Figure 16 As shown, the magnet is a cylindrical structure, and the symmetrical edges of the cylinder are trimmed so that the cross section of the magnet is a double D-shaped structure, with the first pole band and the second pole band closely attached to the plane of the trimmed edge.

[0075] Place the end of the magnet with the north and south poles marked N on the outside. This will help you know the north and south pole directions of the capsule when assembling it.

[0076] 1d) If Figure 17 As shown, the magnet, battery and first pole piece are sheathed in a heat shrink tube, so that the first pole piece, magnet, battery and second pole piece are integrated into a structure. Figure 3 shown.

[0077] 2) Molding the capsule core: Assemble a first PCB board above the magnet and a second PCB board below the battery; insert the end of the first pole piece into the first welding point hole of the first PCB board; insert the end of the second pole piece into the second welding point hole of the second PCB board.

[0078] like Figure 18 、 Figure 25 、 Figure 26 As shown, in this embodiment, when assembling the second PCB board, a support frame 11 is set between the battery and the second PCB board. The support frame includes a frame body whose lower surface corresponds to the contour of the second PCB board; and a battery supporting plane 11a is set on the upper surface of the frame body.

[0079] The support frame 11 is provided with a clearance space 11 b corresponding to the electronic components of the second PCB board.

[0080] The thickness of the support frame 11 is greater than the height of the electronic components on the second PCB board, which can effectively prevent the electronic components from being compressed.

[0081] The support frame 11 is provided with an antenna avoidance space 11c and two second pole piece avoidance spaces 11d. The setting of the avoidance spaces prevents the electronic components on the PCB from being pressed, thereby protecting the electronic components.

[0082] 3) Make an integral capsule core: Figure 18 As shown, the formed capsule core is placed into the magnetically controlled capsule core assembly tooling; Figure 19 As shown, after the capsule core is in place, rotate the upper cover; Figure 20 As shown, the upper cover and the lower cover are buckled together.

[0083] like Figure 21 、 Figure 22 As shown, a soldering iron tip L is used to pass through the soldering iron tip avoidance space 110 of the upper cover to weld the end of the first electrode piece and the first PCB board into one.

[0084] like Figure 23 、 Figure 24 As shown, the tooling is turned over so that the upper cover is placed on plane B, and a soldering iron tip L is used to pass through the soldering iron tip avoidance space 210 of the lower cover to solder the end of the second electrode to the second PCB board.
