Description

Folding screen damping mechanism buckle righting device

Technical Field

The invention relates to the technical field of folding screen damping mechanisms, in particular to a buckle correcting device of a folding screen damping mechanism.

Background

The hinge rotating shaft of the folding screen is an important component of the folding screen mobile phone and generally comprises a shaft body, two wing plates, a damping component and a gear set; the two wing plates are rotatably connected to two opposite sides of the shaft body through the rotating shaft and used for being connected with two main bodies of the folding screen mobile phone, and the two main bodies of the folding screen realize reciprocating overturning through the two wing plates and the shaft body. In addition, the two wing plates can realize synchronous overturning through the gear set. The damping component is connected with the rotating shaft of the wing plate and is used for providing damping sense when the wing plate is overturned.

The damping component comprises a damping shaft, and a buckle, a gasket, an upper support plate, a spring and a lower support plate which are sequentially sleeved on the damping shaft from top to bottom. The clamping buckle is clamped at the top end of the damping shaft, the elastic force of the spring pushes the upper support plate and the gasket upwards to the clamping buckle, the clamping buckle limits the gasket, the gasket is prevented from continuously moving upwards, and therefore the gasket is limited on the damping shaft.

After the buckle is assembled on the damping shaft, the buckle is pushed to rotate around the damping shaft to a preset position, and the buckle can be clamped on the damping shaft more firmly at the preset position, so that the falling probability of the buckle is greatly reduced.

However, the hinge shaft of the folding screen belongs to a precise piece, and the volume of the hinge shaft is small. The buckle is one of the components in the hinge shaft of the folding screen, which belongs to the micro-component, the size is about 1cm, the small size of the buckle causes that the buckle is extremely difficult to be precisely pushed to rotate to a preset position in the process of assembling the buckle, and the periphery of the buckle cannot provide enough operation space for tools to push the buckle. In addition, under the action of the extrusion force of the spring, the gasket and the buckle are in close contact, so that the friction force between the buckle and the gasket is also promoted to be large, and the buckle is difficult to push to rotate around the damping shaft. The above factors are combined, so that the difficulty of the buckle assembly process is high.

Currently, the available assembly methods include: before assembling the buckle, adopting a visual detection system to assist in positioning, moving the buckle to a preset position, then directly pressing the buckle to the damping shaft, and assembling the buckle in place in one step. However, the buckle belongs to the micro-component, and although the position of the buckle is accurate before the buckle is pressed to the damping shaft, the buckle is easy to shift in position due to the stress of the buckle in the process of pressing the buckle, so that the problem that the buckle is not assembled in place or the assembly position is inaccurate is caused, and the assembly yield is low.

If adopt artifical assembly, it can be after the buckle is impressed the damping axle, reuse thimble or other instrument with buckle position fine setting, makes buckle assembly in place, and on the one hand, this kind of scheme cost of labor is high, and is inefficiency, on the other hand, and it still can't solve the problem of assembly precision, and the buckle still can't accurately rotate to preset the position.
