Description

Technical Field

[0001] This utility model relates to the field of shell welding, and in particular to a welding positioning fixture for a connector plate shell with wire. Background Technology

[0002] When using an ultrasonic welding machine to weld the adapter plate shell of the external stimulator unit, the shell is difficult to lay flat due to the wires on both sides and their rigidity. Furthermore, the wires are connected to other structural components of the external stimulator, making the shell prone to rotation during the downward pressure of the welding arm. This can lead to welding failure and a low yield rate. Ensuring a high yield rate requires two people: one to restrain the wires and the other to adjust the position of the adapter plate shell and operate the ultrasonic welding machine. This results in higher production costs and lower welding efficiency.

[0003] Therefore, a welding and positioning fixture for a connector plate housing with wires is urgently needed in this field. Utility Model Content

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be further described in detail below with reference to specific examples and accompanying drawings.

[0024] To improve welding efficiency and yield, this utility model proposes a welding positioning fixture for a connector plate housing with wire, such as... Figure 1 As shown, its structure includes: a lower mold 10, the upper surface of which is provided with a lower positioning groove 11 adapted to the shape of the adapter plate shell to be welded, and is detachably connected to the base of the ultrasonic welding machine; an upper mold 20, the lower surface of which is provided with an upper positioning groove (not shown) adapted to the shape of the adapter plate shell, and is detachably connected to the welding arm of the ultrasonic welding machine; and left and right hanging ears 30, which are located on the left and right sides of the welding arm shell and are configured to constrain the wires on both sides of the adapter plate shell to be welded during the welding process, so that the wires on both sides, which have a certain hardness and weight, hang naturally when the adapter plate shell is to be welded and during the welding process, preventing the wires on both sides from tilting or twisting, and ensuring that the adapter plate shell matches the lower mold 10 stably in a natural state without external interference, without tilting, twisting or even flipping. The entire welding process does not require personnel to support the wires on both sides, and welding can be completed by only one person, significantly improving the welding efficiency of the adapter plate shell. Furthermore, it should be noted that the application of this utility model is not limited to the above-mentioned application scenarios. This utility model can be used to weld any housing with wires. In this case, it is only necessary to replace the upper mold and the lower mold with positioning grooves of corresponding shapes, such as welding the housings of wired headphones, wired hearing aids, wired headsets, etc.

[0025] In this embodiment, during use, the adapter plate housing to be welded can be first placed horizontally in the lower positioning groove 11 of the lower mold 10. Then, the wires on both sides or the wires and their end connectors are fixed to the left and right hanging ears 30, so that the wires on both sides hang naturally. The weight of the wires on both sides presses down on the adapter plate housing to be welded to keep it in close contact with the lower positioning groove 11. Then, pressing the start button causes the welding arm to move the upper mold 20 downward and cooperate with the lower mold 10 to press the adapter plate housing to be welded and apply ultrasonic vibration of a preset frequency to weld the two sections of the adapter plate housing together. The above solution improves welding efficiency and ensures welding quality.

[0026] In one embodiment, the sum of the depths of the lower positioning groove 11 and the upper positioning groove 21 is less than the thickness of the adapter plate housing to be welded. Specifically, ultrasonic welding relies on ultrasonic vibrations to generate heat through friction between the objects to be welded, thus achieving the welding purpose. Therefore, close contact between the objects to be welded is crucial. To ensure close contact between the two sections of the adapter plate housing to be welded, in this embodiment, the sum of the depths of the lower positioning groove 11 and the upper positioning groove is designed to be less than the thickness of the adapter plate housing to be welded, and pressure is applied accordingly.

[0027] In one embodiment, see Figure 2 The lower positioning groove 11 includes: a transition plate housing positioning groove 111 disposed at the center of the lower mold; and wire positioning grooves 112 extending from the transition plate housing positioning groove 111 to the opposite two side edges of the lower mold. Specifically, the wire positioning grooves 112 are used to ensure the stability of the wire in mates with the lower mold 10 in a predetermined direction, angle, and position during the pressing down of the welding arm.

[0028] In one embodiment, see Figure 3 The wire positioning groove 112 is equipped with a locking post 1121, which is fixed to one side wall of the wire positioning groove 112 and has a gap with the opposite side wall. The locking post 1121 can be either a rigid locking post or an elastic locking post. In use, the wire can be elastically inserted through the gap between the locking post 1121 and the opposite side wall. Subsequently, the locking post 1121 fixes the wire at the root of the adapter plate housing, preventing the adapter plate housing from deflecting during downward welding.

[0029] In one embodiment, see Figure 4The wire positioning groove 112 is further equipped with a retaining spring 1122 and an arc-shaped clip 1123. One end of the retaining spring 1122 is fixedly connected to the concave side of the arc-shaped clip 1123, and the other end is sleeved on a rigid clip post, with the convex side of the arc-shaped clip 1123 elastically abutting against the opposite side wall of the wire positioning groove 112. In use, the wire can be elastically inserted from one side of the arc-shaped clip 1123, and the clip post 1121 then fixes the wire at the root of the adapter plate housing, preventing the adapter plate housing from deflecting during downward welding. Compared to the aforementioned embodiment that only has a clip post 1121, this embodiment can further avoid damage to the wire.

[0030] In one embodiment, see Figure 5 The wire positioning groove 112 is further equipped with a retaining spring 1122 and an S-shaped clip 1124. One end of the retaining spring 1122 is fixedly connected to the concave side of the S-shaped clip 1124, and the other end is sleeved on a rigid clip post, with the convex side of the S-shaped clip 1124 elastically abutting against the opposite sidewall of the wire positioning groove 112. In use, the wire can be elastically inserted from one side of the S-shaped clip 1124, and the clip post 1121 then fixes the wire at the root of the adapter plate housing, preventing the adapter plate housing from deflecting during downward welding. Compared to the aforementioned embodiment that only has a clip post 1121, this embodiment can further avoid damage to the wire.

[0031] In one embodiment, the left and right ear loops 30 include: hooks (not shown) or T-shaped brackets (see [link]). Figure 1 ).

[0032] In one embodiment, see Figure 6 The cross arm of the T-shaped bracket 30 is also provided with multiple positioning magnetic blocks 31 and / or multiple positioning bevels 32. Specifically, the positioning magnetic blocks 31 are used to magnetically position wires with magnetic ends and adjust them according to the length of the wire; the positioning bevels 32 are used to engage and position wires with non-magnetic ends and adjust them according to the length of the wire.

[0033] In one embodiment, the welding positioning fixture for the adapter plate housing with wire of this utility model further includes: limiting posts (not shown), attached to the four side walls of the lower mold 10; and a buffer spring (not shown), disposed between the lower mold 10 and the base of the ultrasonic welding machine. The buffer spring is used to prevent excessive pressure from the welding arm from damaging the adapter plate housing to be welded, while the limiting posts are used to prevent the lower mold 10 from moving horizontally during the compression of the buffer spring.

[0034] The welding positioning fixture for the adapter plate housing with wires in this embodiment can simultaneously constrain the adapter plate housing to be welded and the wires on both sides, thereby greatly improving welding efficiency and welding quality and saving labor.
