[0011] The protection piece in the utility model can be used for tin soldering operation of throttle PCB, and during the operation process, the protection piece is shielded on the dust cover assembly, and the welding point is located in the positioning through slot or below. During the tin soldering operation, since other areas of the dust cover assembly are covered by the protection piece body, the splashed solder during the tin soldering process cannot splash into the covered areas.

[0012] Meanwhile, the positioning through groove is located at the bottom of the sunken part, the upper periphery of the positioning through groove is surrounded by the side end face of the sunken part, the depth between the upper end face of the protector body and the positioning through groove is deepened, and the shielding is formed on the upper ring side face of the positioning through groove.

DETAILED DESCRIPTION

[0023] The technical scheme in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Apparently, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without creative labor belong to the protection scope of the utility model.

[0024] As Figures 1-6 shown, the utility model provides a protection piece and tin soldering tool for throttle valve tin soldering.

[0025] Among them, as Figure 4 , 5 shown, it is an embodiment of tin soldering tool, and the tin soldering tool includes a protection piece for throttle valve tin soldering, dust cover limiting block 2 and tin soldering machine 3. Figures 1-3 It is structural diagram of the protection piece for throttle valve tin soldering.

[0026] As Figure 4 , 5 shown, in tin soldering tool, tin soldering machine 3 is a kind of automatic tin soldering machine, and tin soldering machine 3 includes soldering gun 31, and the lower portion of soldering gun 31 is equipped with slide rail 32, and the upper end of slide rail 32 is connected with the slide block 33 that can slide forwards and backwards, and the upper end of slide block 33 is placed with dust cover limiting block 2, and dust cover limiting block 2 can move in the front and rear direction under the drive of slide block 33. When operating, soldering gun 31 moves to the upper portion of dust cover limiting block 2 and then moves downwards, and is aligned with the welding point 41 below to carry out tin soldering operation.

[0027] Dust cover limiting block 2 is equipped with limiting groove for placing dust cover assembly 4. The limiting groove is upwardly open, and when operating, dust cover assembly 4 is placed in the limiting groove, and welding point 41 faces upwards. The welding point 41 is located on the PCB board in dust cover assembly 4.

[0028] And, the protection piece covers the upper portion of dust cover assembly 4 in limiting groove, as Figure 5 , 6 shown.

[0029] As Figures 1-3 shown, the protection piece in the embodiment includes protection piece body 1, and the bottom of sunken part 11 is equipped with positioning through slot 12 that penetrates upwards and downwards, and the protection piece body 1 is also equipped with insertion slot 13 that penetrates upwards and downwards.

[0030] Specifically, in the embodiment, the lower groove of positioning through slot 12 is located at the lowest point of the entire protection piece body 1. As Figure 3 shown, sealing member 14 is additionally arranged at the lower end of protection piece body 1, and sealing member 14 is distributed along the outer edge of the lower groove of positioning through slot 12, and is used for filling the gap between protection piece body 1 and PCB board during operation. When placing the protection piece on the upper end of dust cover assembly 4, sealing member 14 will be attached to the PCB, and is used for blocking the gap between the lower end of protection piece body and PCB board, so as to prevent liquid solder from passing through the gap.

[0031] The sealing member 14 in this embodiment is a ring-shaped silica gel ring connected to the outer edge of the lower slot of the positioning slot 12.

[0032] Meanwhile, the positioning slot 12 is located at the bottom of the lower recess 11, and the upper outer periphery of the positioning slot 12 is surrounded by the side end surface of the lower recess 11, deepening the depth between the upper end surface of the protective member body 1 and the positioning slot 12, and forming a shield on the side surface of the outer periphery of the positioning slot 12.

[0033] Preferably, a plurality of upper and lower through insertion slots 13 are also provided on the protective member body 1. These insertion slots 13 are upper and lower through, and can be inserted by the protruding end in the dust cover assembly 4, playing a positioning and limiting role. Figure 6 As shown, the insertion piece fixing column 42 is a protruding end for fixing the insertion piece, and the upper end is higher than the upper end surface of the PCB board.

[0034] In the process of covering the protective member on the dust cover assembly 4, the insertion slot 13 on the protective member can be aligned with the corresponding protruding end, and the protective member can be quickly aligned with the dust cover assembly 4, and when the protruding end is inserted into the insertion slot 13, the transverse displacement of the protective member can also be limited.

[0035] The protective member in this embodiment can be used for the soldering operation of the throttle PCB board. In the operation process, the protective member is shielded on the upper end of the dust cover assembly 4, and the soldering point 41 is located below the positioning slot 12 and is not shielded. During soldering operation, since the other areas of the dust cover assembly 4 around the positioning slot 12 are covered by the protective member body 1, the solder splashed during soldering process cannot splash into the covered area.

[0036] In addition, the positioning slot 12 is located at the bottom of the lower recess 11, and also deepens the depth between the upper end surface of the protective member body 1 and the positioning slot 12, forming an inclined surface on the outer periphery side surface of the positioning slot 12, which is the upper end surface of the lower recess 11, and can form a better shield on the side surface of the positioning slot 12; meanwhile, the space above the lower recess 11 with an inclined upper end is larger, and can better adapt to the soldering gun 31 to perform soldering operation on the soldering point 41 at an inclined angle.

[0037] In the soldering process of the PBC board, the protective member described in this embodiment is used to cover the dust cover assembly 4, which can effectively shield the solder splashed during soldering.
