Automatic cleaning device for needle head of display screen dispenser

Abstract

The invention provides an automatic cleaning device for a needle head of a display screen dispenser. The automatic cleaning device comprises a workbench, wherein an operation column is fixedly installed on the right side of the top of the workbench, and a cushion block is fixedly installed on the left side of the top of the workbench. According to the automatic cleaning device for the needle headof the display screen dispenser, an extendable column and a circular ring are arranged, whether a display screen exists at the top of the cushion block or not is sensed through the movement of the extendable column, and a transverse plate fixedly installed inside the extendable column is matched to drive a moving rod to move up and down, so that a switch is turned on, and different adjusting effects at different positions are used, so that an electric control rotating shaft is driven to rotate, the circular ring slides on the outer surface of a dispensing needle, glue leakage on the outer surface and the bottom of the dispensing needle is automatically cleaned while pearl wool inside the circular ring slides on the circular ring, compared with other cleaning modes, the automatic cleaning purpose is achieved by using the gravity of the display screen, and meanwhile, the pearl wool and the circular ring are matched, so that the cleaning effect is better.

Description

technical field [0001] The invention relates to the technical field of display devices, in particular to an automatic cleaning device for a needle of a display screen dispenser.

Problems solved by technology

[0003] Among them, display screens of various sizes and shapes are widely used in daily life, including electronic devices such as mobile phones, tablets, and computers. Since the display screens are assembled by bonding and superimposing multiple layers of materials, during the production process in the workshop, The display screen dispenser is an indispensable equipment, but during the long-term use of the dispenser, the needle of the dispenser needs to be wiped frequently due to glue and other reasons. However, the general factory uses manual wiping. While the wiping effect is poor, the needle is often bent and damaged due to excessive force, which not only increases the production cost, but also seriously affects the production efficiency of the product
