Display screen assembling screw locking mechanism and method

Abstract

The invention relates to the field of display screens, in particular to a display screen assembling screw locking mechanism and method. The mechanism comprises a locking rack, a locking driving assembly and a locking head. The locking rack is fixed to a workbench, and the locking driving assembly is fixed to the locking rack. The output end of the locking driving assembly is connected with the locking head; the output end of the locking head is connected with a jig carrying mechanism, and the output end of the locking head makes contact with a display screen end cover screw hole; the locking driving assembly is used for driving the locking head to move; and the locking head is used for screwing a screw into the display screen end cover screw hole. According to the mechanism, by arranging the locking head, abrasion of a screw bit rod is reduced, and the service life of the screw bit rod is prolonged.

Description

technical field [0001] The invention relates to the field of display screens, in particular to a display screen assembly screw locking mechanism and method. Background technique [0002] The display screen is a display tool that displays a certain electronic file on the screen through a specific transmission device and then reflects it to the human eye. According to the different manufacturing materials, it can be divided into: cathode ray tube display, plasma display, liquid crystal display and so on. The display screen includes a display screen end cover and a display screen shell. Various electrical components are installed inside the display screen shell. The display screen end cover is connected to the rear side of the display screen shell by a plurality of screws to fasten and seal it. The screw connection between the display screen end cover and the display case has an important influence on the performance of the display screen. Whether the screw connection between...

Problems solved by technology

[0004] The existing technology has the following disadvantages: when tightening the screws of the display screen end cover, the screw slider is fixed on the positioning bottom plate, and the screw feeding mechanism feeds the screw to the corresponding hole of the positioning chuck along the internal feeding channel of the screw slider Position the screw; then the tightening machine drives the screw bit through the inner hole of the positioning bottom plate and moves down to the position of the screw in the positioning chuck Drive the screw to move down to stretch the positioning chuck, and then tighten the screw into the screw hole of the display end cover ; and the screw slider is fixedly connected with the positioning base plate, that is, the screw feeding channel inside the screw slider is always connected with the downward movement channel of the screw batch head in the positioning base plate; when the screw feeding mechanism feeds multiple screws at a time due to feeding reasons, Only one screw falls into the position of the screw in the positioning chuck, and the rest of the screws are stuck in the screw feeding channel inside the screw slider; when the tightening machine drives the screw bit through the hole in the positioning bottom plate and communicates with the screw feeding channel, it moves down When the position of the screw in the positioning chuck drives the screw down, the screw bit rod will contact and rub against the remaining screws in the screw feeding channel; thus causing the wear of the screw bit rod, or even jamming the screw bit rod and causing the screw to move down. The screw bit rod is broken; at the same time, the remaining screws in the screw feeding channel cannot be discharged in time, and the next screw feeding will cause more than one screw to be fed; that is, there are always redundant screws and screws in the screw feeding channel. Screw bit shaft friction, which reduces the service life of the screw bit shaft
