Description

Technical Field

[0001] The utility model relates to the technical field of mobile phone middle frame processing jigs, in particular to a narrow space side wall spring piece welding jig. Background Art

[0002] like Figure 1 As shown, during the processing of the existing mobile phone middle frame, two spring clips 3 need to be inserted between the inner side wall 1 of the middle frame and the middle frame structure retaining wall 2 for positioning, and then welded at the welding point 4 of the two spring clips after being horizontally pressed. Due to the structural space limitation of the spring clip, for this narrow space spring clip welding process, it is necessary to consider both the structural fixation of the spring clip and the pressing structure of the spring clip, as well as the requirements of the light shielding and avoidance structure of the welding process, and also the operational convenience of the employees. The single pressure claw structure of the existing spring clip welding process is difficult to meet the requirements of this special narrow space spring clip welding process, and the existing automated process is also difficult to achieve production.

[0007] The spring clip clamping rotating rod structure includes an inclined angle support block, a clamping rotating rod fixing seat, a rotating shaft and a spring clip clamping rotating rod. The inclined angle support block is fixedly mounted with a clamping rotating rod fixing seat. The spring clip clamping rotating rod is rotatably connected to the clamping rotating rod fixing seat via a rotating shaft. The end of the spring clip clamping rotating rod is pressed down to compress the spring clip.

[0008] Preferably, a magnet is provided in the positioning rotating rod fixing seat, and the spring piece positioning rotating rod is a magnetic attraction rod.

[0009] Preferably, the pressing rotating rod fixing seat is provided with a magnet, and the spring piece pressing rotating rod is a magnetic attraction rod.

[0010] Preferably, the tilt angle bracket is a 65 degree tilt angle bracket.

[0011] Preferably, the inclined angle support block is a 45-degree angle support block.

[0012] Preferably, the spring sheet pressing rotating rod and the spring sheet positioning rotating rod are respectively provided with handles.

[0013] The beneficial effects of the utility model are as follows: (1) the spring piece positioning and fixing structure and the spring piece pressing and rotating rod structure of the fixture of the utility model are designed separately, making full use of the narrow structural space, effectively avoiding blocking the path of the welding laser, and solving the problem of spring piece welding process on the side wall of this narrow space; (2) the spring piece positioning and rotating rod is fixed on the positioning and rotating rod fixing seat under the magnetic force of the magnet, and the independent horizontal positioning structure plays a role in accurate positioning and convenient pick-up and placement operations. There are two groups of positioning columns of different sizes in front of the spring piece positioning and rotating rod, which play the role of foolproof positioning of the spring piece. At the same time, two welding spring pieces can be positioned on one positioning rod, saving design space and improving welding efficiency; (3) the spring piece pressing and rotating rod adopts a 45-degree pressing design to ensure the activity space of the spring piece pressing and rotating rod, and at the same time ensure that the spring piece to be welded is fully pressed under the magnetic force of the magnet, thereby ensuring the connection strength of the spring piece welding.
