Technical Field

The utility model belongs to the technical field of the material transport upset.

Background

The inner structure of the keyboard mainly comprises a control circuit board, keys, a bottom plate, a panel and the like. The bottom plate is usually made of a metal sheet through stamping, and the keyboard bottom plate needs to be turned over and the like in the stamping process; the traditional keyboard base plate overturning operation is carried out manually, so that the defects of low efficiency, easy error and inconvenience for organizing assembly line processing exist; therefore, it is an urgent need to solve the above-mentioned problems.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a keyboard floor turning device to solve the problem of the inefficiency of upset keyboard floor.

In order to achieve the above object, the utility model discloses a basic scheme provides a keyboard floor turning device, including pedestal and clamping mechanism, the pedestal includes protruding portion and horizontal part, offers the cavity in the pedestal, and in the cavity extended to protruding portion and horizontal part, telescopic cylinder about being equipped with in the cavity of pedestal horizontal part, telescopic cylinder's flexible end extended in the pedestal outside, and telescopic cylinder's flexible tip fixedly connected with brace table, protruding portion are close to horizontal part one side and rotate and are connected with clamping mechanism, and clamping mechanism locates the horizontal part top.

The principle of the basic scheme is as follows: the keyboard bottom plate is placed at a supporting table top surface, and the supporting table rises under the telescopic action of the telescopic cylinder until the supporting table top surface and the clamping mechanism are located at the same horizontal height. The clamping mechanism clamps the keyboard bottom plate. Considering that keyboard bottom plate length or width are great, for guaranteeing keyboard bottom plate upset smoothly, prevent that the keyboard bottom plate from touching the brace table among the upset process, consequently the brace table contracts and descends under telescopic cylinder drives after clamping mechanism presss from both sides tightly, and then makes the brace table descend to the direction of keeping away from clamping mechanism, avoids clamping mechanism to touch the brace table at the in-process of upset, rotates clamping mechanism at last and makes the keyboard bottom plate accomplish the upset. This technical scheme does not receive the hindrance of brace table for guaranteeing the keyboard bottom plate at the in-process of upset, and this technical scheme is before upset keyboard bottom plate, and the shrink of drive brace table of telescopic cylinder descends for the interval grow between brace table and the clamping mechanism, and then reach the technological effect of safe upset keyboard bottom plate.

The beneficial effect of this basic scheme lies in: compare in prior art's keyboard bottom plate device, this technical scheme has enlarged the interval between clamping mechanism and the brace table when the upset, has improved the security of the in-process of keyboard bottom plate upset, effectively avoids keyboard bottom plate to appear colliding the damage in the upset in-process.

Further, a slide bar is fixedly connected to the bottom of the support table, one end, far away from the support table, of the slide bar is connected to the seat body in a sliding mode, a rack with the length smaller than that of the slide bar is arranged on the outer wall, close to the support table, of the slide bar, the extending direction of the rack is parallel to the axial direction of the slide bar, a gear meshed with the rack is arranged in a cavity of the horizontal portion of the seat body, and the gear further comprises a transmission mechanism.

After the keyboard bottom plate at the top of the supporting table is clamped by the clamping mechanism, the supporting table can descend under the driving of the telescopic cylinder, and the sliding rod slides in the cavity of the seat body in the descending process of the supporting table. Since the length of the rack is shorter than that of the slide bar, the rack is not engaged with the gear during the initial lowering of the support platform.
