Description

Display Maintenance Tool

technical field

The utility model relates to the technical field of machine tools, in particular to a maintenance tool for a display screen.

Background technique

LED display has become the new darling of the display field today because of its ultra-high-definition display, high brightness, low power consumption, and long service life that cannot be compared with traditional display devices such as LCD screens and projectors. It has been widely used in meeting rooms, clubs, shopping malls, studios, monitoring halls and other places. Among them, because the front maintenance LED display has many advantages such as small space occupation, convenient maintenance, and strong environmental adaptability, it is more and more popular in the field of LED display. When maintaining this type of display screen, maintenance personnel usually need to remove the entire display unit including the LED module, power supply, etc. from the front of the display screen for maintenance.

For front-maintenance LED displays, the following two tools are currently used to achieve front-maintenance: one is to use a special barb tool. The mask at the four corners of the surface of the light board is torn off, and then use a special barb tool to hook out the LED light board through the square holes reserved on the four corners of the box for maintenance. The above-mentioned maintenance method is complex, difficult and expensive to maintain, and the display effect of the display screen will be adversely affected after the replacement of the mask. At the same time, it is easy to damage the mask in front of the display screen and the lamp beads on the display board by using a barb tool.

Another way is to use a simple strong magnetic tool. In this maintenance method, a piece of iron will be set behind each display unit to cooperate with the strong magnetic tool, and the magnetic force between the strong magnetic tool and the iron plate will be used The principle is greater than the magnetic force of the permanent magnet used to fix the display unit, and the LED display unit is pulled off from the frame structure for maintenance. This maintenance method is very easy to cause a series of problems such as the falling off of the LED lamp beads on the display unit, the damage of the mask, and the deformation of the PCB board. The maintenance cost is high and the maintenance efficiency is low.
