Description

Electronically controlled front maintenance splicing frame

technical field

The invention relates to a splicing frame, in particular to a front maintenance type splicing frame operated in an electric mode.

background content

Existing large-scale LED screens are generally formed by splicing several display screens (LCD splicing screens/LED full-color screens) by splicing units. The traditional LCD splicing unit is fixed in one body, and the display can only be operated from the back of the LCD splicing unit when disassembling, replacing, and repairing the display. When the LCD splicing unit is installed on a carrier such as a wall, it cannot be operated from the back, and maintenance work becomes very difficult.

In this case, a splicing frame that can be stretched back and forth has become popular in the market in recent years. The front fixing seat used to fix the display screen on each splicing unit can be stretched back and forth. The front mount stretches forward into extension, eliminating the need to access it from the rear. At present, most of the existing splicing frames that can be stretched back and forth use hydraulic cylinders, and need to manually stretch or push the front fixing seat to achieve stretching or contraction. The weight of the front fixing seat of the splicing unit is usually relatively large, and this stretching method is very laborious. When multiple display screens need to be maintained, each splicing unit needs to be manually stretched and stretched, and the work intensity is very high.

Start working under the control of the device; the output shaft of the motor drives the screw to start rotating; one end of the telescopic rod that is nested with the screw moves backwards under the linkage with the screw, and the other end of the telescopic rod is at the end of the telescopic rod Driven by the rotation relative to the front fixed seat, the distance between the two ends of the telescopic rod becomes larger and larger, showing a stretched state, and generates a forward thrust to the front fixed seat; at this time, the telescopic bracket also stretches under the action of the thrust Finally, the front fixing seat moves forward, and then the installation, maintenance or replacement of the display screen begins;

After the installation, maintenance or replacement of the display screen is completed, a contraction control signal is sent to the motor controller of the electric linear drive device of the corresponding splicing screen through the general control system. Under the control of the motor controller, the motor output shaft and screw of the corresponding motor are both Reverse rotation, so that the telescopic rod drives one end of the electric telescopic support to move forward; the other end of the electric telescopic support rotates in the opposite direction accordingly, and the distance between the two ends of the electric telescopic support becomes smaller and smaller, showing contraction In this state, a backward pulling force is produced on the front fixing seat, and the telescopic bracket also shrinks thereupon, and finally the front fixing seat moves backward and is in a folded state again.
