Description

Technical Field

[0001] The utility model relates to a welding jig suitable for a moving iron unit sound tube. Background Art

[0002] Headphones are a common small electronic device that can convert the electrical signals it receives into audible audio signals. They allow users to listen to sounds alone without affecting others, while also isolating the user from the impact of surrounding sounds.

[0003] However, unlike the micro speakers in mobile phones, earphones are small in size and are generally separated from the audio player. The earphone body not only includes the speaker unit and the corresponding cavity structure that carries the speaker unit, but also includes a microphone for picking up sound, wires for transmitting audio signals, and integrated circuit boards for processing audio signals, etc. It can be considered a small audio electronic device with a very high degree of integration. For example, the highly integrated and intelligent TWS (True Wireless Stereo) earphones are also equipped with batteries, charging management circuits, numerous sensors, touch controllers, Bluetooth transmission chips, etc.

[0004] A search revealed the following patent: "A headset (CN202010544604.8) comprises a headset housing and a main housing, as well as earbuds, a wire, a bone conduction microphone, an integrated silicone sleeve, a balanced armature driver, and a pickup microphone module. The earbud sleeve is mounted on the sound outlet duct of the headset housing and is provided with an airbag for insertion into the human ear. The balanced armature driver and the bone conduction microphone are separately welded to the core wire of the wire, assembled within the integrated silicone sleeve, with the bone conduction microphone positioned above the balanced armature driver. The headset housing is assembled above the integrated silicone sleeve. The integrated silicone sleeve is provided with a microphone hole connected to the bone conduction microphone, the microphone hole facing the microphone hole on the headset housing, and the microphone hole is connected to the airbag. The integrated silicone sleeve is mounted within the sound outlet duct and is provided with a balanced armature sound outlet tube connected to the balanced armature driver, the balanced armature sound outlet tube facing the main sound outlet on the headset housing. The above structure utilizes integrated silicone for connection, resulting in poor installation stability.

[0005] In view of the above-mentioned defects, the designers have actively carried out research and innovation in order to create a new type of welding fixture suitable for the moving iron unit sound tube, making it more valuable for industrial use. Utility Model Content

[0023] Example

[0024] like Figure 1 As shown, a welding jig suitable for a moving-arm unit sound tube includes a first fixing base 1, to which a mounting base 2 is connected. One side of the mounting base 2 is connected to a positioning and fixing component 3 for positioning and fixing the product, and the other side of the mounting base 2 is connected to a welding component 4 for welding the product.

[0025] The positioning and fixing assembly 3 includes a second fixed base 31, which is connected to a fixed base 32. A sliding groove 33 is provided on the fixed base 32. A sliding push block 34 is connected to one side of the sliding groove 33. A push rod 35 is passed through one side of the fixed base 32. The push rod 35 passes through the fixed base 32 and is connected to the sliding push block 34. A positioning and fixing block 36 is connected to the other side of the sliding groove 33. A positioning groove is provided in the positioning and fixing block 36. A positioning block 37 is connected to the positioning groove. A product fixing block 38 is slidably connected to the positioning groove above the positioning block 37. The product fixing block 38 is arranged opposite to the sliding push block 34.

[0026] The welding assembly 4 includes a welding fixing seat 41, a vertical plate 42 is connected to the welding fixing seat 41, a welding connection frame 43 is connected to the vertical plate 42, a welding connection frame 43 is connected to a welding drive device 44, a connecting rod 45 is connected to the driving shaft of the welding drive device 44, a welding rod 46 is connected to the connecting rod 45, and a welding head 47 is connected to the welding rod 46.

[0027] In the present invention, the second fixed base 31 is connected to an auxiliary fixing column 39 , and the auxiliary fixing column 39 is connected to a rotatable auxiliary follower clip 310 , which can ensure stable movement of the product and guarantee the welding quality of the product.

[0028] In the present invention, the second fixed base 31 is connected to a positioning column 311, and the positioning column 311 is connected to a rotatable positioning clip 312 that is aligned with the position of the positioning push rod. Ensure that the push rod is pushed into place and will not affect the movement of the product.

[0029] The welding drive device 44 in the present invention is a cylinder.

[0030] In the present invention, the welding connection frame 43 is connected with a guide rod 48, and the guide rod 48 is connected to the driving shaft of the welding drive device 44 through a connecting block, so as to ensure the stability of the product.

[0031] The working principle of this utility model is as follows:

[0032] During specific work, the product is placed on the product fixing block and fixed by the auxiliary follow-up clip. Then the push rod is used to push the slider to make the product fixing block slide along the positioning groove to the specified position (that is, the position where the push rod is limited). Then the welding cylinder pneumatically drives the drive shaft to descend and drives the connecting rod to descend together. When the connecting rod descends, it also drives the welding head to descend and contact the product to achieve welding.

[0033] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0034] In the description of this application, it should be noted that the terms "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings, or are the orientations or positional relationships in which the product of this application is typically placed when in use. These terms are intended solely to facilitate the description of this application and simplify the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," etc., etc., are used solely to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0035] In addition, the terms "horizontal" and "vertical" do not mean that the components must be absolutely horizontal or vertical, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0036] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "disposed," "installed," "connected," and "connected" should be understood in a broad sense.
