[0022] like Figures 2 to 10 The speaker terminal wire soldering fixture shown includes a positioning bracket 1 and a wire clamping bracket 2. Please refer to the details. Figure 2 and Figure 3 In an embodiment of this utility model, the positioning bracket 1 has an inclined support portion 11 and a stop portion 12. The inclined support portion 11 extends to the top of the positioning bracket 1, and the stop portion 12 is disposed at the bottom of the inclined support portion 11. The included angle between the inclined support portion 11 and the stop portion 12 is configured to be the same as the included angle between the two sides of the speaker frame, so that one side wall of the frame can be placed in a horizontal state. It should be noted that, in an embodiment of this utility model, the speaker is used to represent the product body 02. By setting the stop portion 12 and the inclined support portion 11, when the speaker is placed on the inclined support portion 11, the front panel of the speaker fits against the inclined support portion 11, and the bottom of the speaker abuts against the stop portion 12. Through this structural form, the solder pad 021 on the speaker frame can be horizontally positioned above. Of course, it should be noted that the included angle between the inclined support portion 11 and the stop portion 12 is adapted to the included angle between the side wall of the speaker frame and the speaker panel. It can be as follows: Figure 3 The vertically arranged stop 12 shown can also be as follows: Figure 4 The inwardly inclined stop portion 12 shown in the diagram has an included angle that varies depending on the different structures of the speaker frame, in order to keep the side wall of the frame horizontal on the upper surface.

[0023] Please continue to refer to Figure 3In an embodiment of this utility model, the wire clamping bracket 2 has two parallel wire clamping portions 21, and the distance between the two wire clamping portions 21 matches the distance between the two solder pads 021 on the speaker. It should be noted that the wire clamping portions 21 can have various structural forms; for example, they can be fixed using clamps, or they can be other conventional structural forms in the art. In an embodiment of this utility model, such as... Figure 2 As shown, the inclined support 11 also has two vertically arranged connecting parts 13 on both sides. When the wire clamp bracket 2 is connected to the connecting parts 13, the stripper 011 on the clamped plug wire 01 is parallel to the solder pad 021. The connection between the wire clamp bracket 2 and the connecting parts 13 can also be of various forms, such as snap-fit ​​or magnetic connection.

[0024] When soldering the speaker's terminal wires, first, invert the speaker so that the speaker's sound-emitting panel is in contact with the inclined support 11. Then, rotate the speaker so that the solder pad 021 is in a horizontal position on its upper surface. Next, fix the plug wires 01 on the wire clamp bracket 2 so that the two plug wires 01 are parallel, and the distance from the stripper tip 011 protruding from the side of the wire clamp bracket 2 is the same as the distance from the wire clamp bracket 2 to the solder pad 021. Then, connect the wire clamp bracket 2 to the connecting part 13, as follows. Figure 5 As shown, the stripper head 011 is attached to the pad 021 and finally fixed by soldering with a soldering head. Furthermore, it should be noted that to further improve the connection reliability between the stripper head 011 and the pad 021, a groove adapted to the stripper head 011 can be formed on the pad 021, allowing the stripper head 011 to be pressed into the hole of the pad. This design can prevent the risk of floating wires during soldering.

[0025] In the above embodiment, by setting the inclined support part 11 and the stop part 12 on the positioning bracket 1, the solder pad 021 is in a horizontal state after the speaker is placed on the positioning bracket 1. By connecting the wire clamping bracket 2 that holds the plug wire 01 in parallel with the connecting part 13 on the positioning bracket 1, the stripper 011 on the plug wire 01 is parallel and attached to the solder pad 021. Compared with the prior art, the reliability of the welding between the stripper 011 and the solder pad 021 is guaranteed, the welding deviation, defects and errors are reduced, and the welding quality is improved.

[0026] Based on the above embodiments, in order to further improve the accuracy of speaker positioning, such as Figure 6 and Figure 7As shown, the support has a positioning groove 111 with a width adapted to the outer diameter of the speaker, and the bottom of the positioning groove 111 extends to the stop portion 12. With this structural configuration, the sound-emitting surface of the speaker is in contact with the bottom wall of the positioning groove 111, the two sides of the speaker are close to the two side walls of the positioning groove 111 respectively, and the bottom abuts against the stop portion 12, thereby preventing the speaker from wobbling left and right and improving welding stability.

[0027] In addition, please continue to refer to Figure 6 and Figure 7 In this embodiment of the invention, the included angle between the stop portion 12 and the positioning groove 111 enables the speaker to be positioned and pressed, preventing its bottom from shaking. To further improve the stability of the speaker positioning, a first magnet 112 is embedded in the side of the positioning groove 111 away from the stop portion 12. At least one first magnet 112 is provided, and the position of the first magnet 112 overlaps with the edge of the speaker. Through the attraction of the first magnet 112, the side of the speaker away from the stop portion 12 is also attracted to the positioning groove 111. Through the combination of the above structures, the speaker can be quickly positioned in the positioning groove 111.

[0028] In an embodiment of this utility model, in order to further achieve rapid speaker positioning and ensure that pad 021 is accurately positioned horizontally, please refer to... Figure 6 and Figure 7 The top of the stop portion 12 also has a protrusion 121, which extends toward the support portion, and the end face of the protrusion 121 toward the extension portion has a recessed groove 122, which is adapted to the support rib on the speaker frame. Figure 7 As shown, the speaker frame has four support ribs, and the solder pads 021 are fixed on the support ribs. The position of the positioning ribs is fixed by the setting of the slot 122, so that the solder pads 021 on the opposite positioning ribs are exactly opposite to the slot 122 without adjusting the speaker placement angle.

[0029] Please continue to refer to Figure 3 In embodiments of this utility model, the wire clamping bracket 2 has a strip-shaped structure, and the length of the wire clamping bracket 2 is not less than the farthest distance between the two connecting parts 13. The strip-shaped structure facilitates manufacturing and processing, and also facilitates connection with the connecting parts 13. In some embodiments of this utility model, the specific structure of the wire clamping bracket 2 is as follows: Figure 8As shown, the wire clamping part 21 is disposed on the upper surface of the wire clamping bracket 2, including a wire feeding groove 211 extending through the width of the wire clamping bracket 2, and two parallel wire clamping posts 212, the distance between the two wire clamping posts 212 being no greater than the outer diameter of the plug wire 01. The wire feeding groove 211 ensures that the wire harness remains horizontal when it is in contact with the bottom of the wire feeding groove 211, and the wire clamping posts 212 facilitate clamping the wire harness. Furthermore, in this embodiment of the invention, to avoid damage to the cable insulation during clamping, please refer to... Figure 8 At least one clamping post 212 is also fitted with a silicone sleeve 213. Since the silicone sleeve 213 is made of flexible material, it can not only avoid damage to the insulation, but also improve the clamping stability through the deformation of the silicone sleeve 213.

[0030] Please continue to refer to Figure 9 In an embodiment of this utility model, the lower surface of the cable clamp 2 also has a recessed groove 22, the shape of which is conformed to the side wall of the speaker frame. The cable clamp 2 also has a direction indicator mark 22a. Thus, through the conformed design of the groove 22, such as... Figure 2 As shown, the pressure groove 22 fits snugly against the speaker frame, and after the wire clamp bracket 2 is connected to the connecting part 13, the speaker can be further prevented from shaking during the movement of the entire fixture.

[0031] For details regarding the specific connection structure between the wire clamp bracket 2 and the connecting part 13 in the embodiments of this utility model, please refer to... Figure 9 and Figure 7 The lower surface of the wire clamp bracket 2 is also provided with two protruding first positioning posts 23. The positions of the two first positioning posts are respectively adapted to the two connecting parts 13. The connecting parts 13 are columnar, and the top of the connecting parts 13 has a magnetic groove 131 adapted to the first positioning posts 23. The magnetic groove 131 and the first positioning posts 23 are both embedded with second magnets 231. It should be noted that the two opposing second magnets 231 generate a magnetic attraction force, so that the wire clamp bracket 2 is connected to the connecting parts 13, and the protruding first positioning posts 23 can be precisely engaged in the magnetic groove 131. Through this structural design, not only is the positioning accurate, but the operation is also convenient.

[0032] In embodiments of this utility model, such as Figure 10 As shown, the fixture also includes a positioning base 3 detachably connected to the bottom of the positioning bracket 1. The positioning base 3 has a second positioning post 31 that mates with the bottom of the positioning bracket 1. The positioning base 3 is used to fix the fixture to the welding machine. In this embodiment of the invention, the second positioning post 31 is made of stainless steel SUS304 to improve wear resistance and avoid welding deviations caused by fixture wear. After assembly, the fixture can be picked up by a robotic arm and placed on the welding equipment for automated welding.
