Quickly positionable FPC pad alignment structure

Abstract

This invention provides a rapidly positioning FPC pad alignment structure, comprising: a support frame, a positioning active component in the middle of the support frame, a compensation positioning component mounted on the top of the positioning active component, driven positioning components rotating at both ends of the bottom of the positioning active component, and position fine-tuning components mounted at both ends of the support frame. This invention provides a rapidly positioning FPC pad alignment structure. Through the coordinated use of the positioning active and driven positioning components, the elastic pressure of the active component synchronously drives the elastic movement of the driven component, allowing for adaptation to pad structures of different sizes without the need for subsequent mold changes. Furthermore, the compensation positioning component and position fine-tuning component on the inner wall absorb pad positional deviations, ensuring the pads are always centered and preventing poor soldering due to misalignment. Simultaneously, more precise positional adjustments can be made to the pad structure to reduce positioning errors.

The first elastic element 23 is used for the elastic reset of the positioning support structure 22.

[0026] When the structure is moved downward, the bottom positioning support structure 22 can move downward, and the first elastic element 23 on the inner wall can provide elastic support, reducing structural deviations during positioning.

[0027] The positioning active component 2 includes, but is not limited to, pneumatic pressing type and spring pressing type; in this embodiment, the positioning active component 2 is preferably spring pressing type.

[0028] The compensation positioning component 3 includes a positioning plate 31 and a slider structure 33. The positioning plate 31 has a sliding groove structure 32 at both ends, which is used for the sliding position of the slider structure 33. The slider structure 33 has telescopic support members 34 installed at both ends, and elastic support members 35 are installed on the side of the telescopic support members 34. The elastic support members 35 are used for elastic compensation of the slider structure 33.

[0029] When precisely positioning the internal pads, the bottom slider structure 33 slides inside the groove structure 32, and the slider structure 33 is elastically supported by the elastic support member 35 to ensure that the top positioning plate 31 is in a pre-accurate position.

[0030] Among them, the compensation positioning component 3 includes, but is not limited to, elastic buffer type and airbag buffer type; in this embodiment, the compensation positioning component 3 is preferably elastic buffer type.

[0031] The driven positioning component 4 includes a fixed slide groove 41, inside which a slider 42 slides.

[0037] The working principle of the FPC pad alignment structure with rapid positioning provided by this utility model is as follows:

[0038] When positioning the solder pads, the device first places solder pads of different sizes on the inner top of the compensation positioning component 3. After placement, the entire compensation positioning component 3 is moved downwards and pressed down. When the compensation positioning component 3 moves downwards, it will simultaneously drive the movement of the driven positioning components 4 at both ends, thereby elastically positioning the internal solder pads. Subsequently, the position fine-tuning components 5 at both ends are rotated to further adjust the solder pads. In conjunction with the compensation positioning component 3, the solder pads can be ensured to be in a good soldering position. At the same time, the internal structure of the position fine-tuning component 5 will slide and lock the compensation positioning component 3 to ensure accurate structural positioning.

[0039] Compared with related technologies, the FPC pad alignment structure with rapid positioning provided by this utility model has the following beneficial effects:

[0040] To improve ease of use when positioning the solder pads, the device employs a combination of an active positioning component 2 and a driven positioning component 4. This allows the driven component to move elastically in tandem with the active component's downward pressure, eliminating the need for mold replacements and adapting to solder pad structures of varying sizes, thus enhancing the device's practicality. Furthermore, during solder pad positioning, the compensation positioning component 3 and position fine-tuning component 5, located on the inner wall, absorb positional deviations, ensuring the solder pads remain centered and preventing soldering defects caused by misalignment. Simultaneously, more precise positional adjustments can be made to the solder pads to minimize positioning errors.
