Automatic grade classification casing equipment for LCD screens

Abstract

The invention discloses automatic grade classification casing equipment for LCD screens. The automatic grade classification casing equipment for LCD screens comprises a screen conveyor line, an emptycase conveyor line, a full case conveyor line and a plurality of separation casing units. The classification casing units are arranged in parallel, and the screen conveyor line, the empty case conveyor line and the full case conveyor line are arranged in the separation casing units in a penetrating manner. Each classification casing unit comprises an adsorbing and carrying mechanism and a case body positioning mechanism. The adsorbing and carrying mechanism can adsorb and carry LCD screens conveyed by the screen conveyor line and separating cotton conveyed by the empty case conveyor line. Thecase body positioning mechanism can position empty cases and full cases on the empty case conveyor line and the full case conveyor line along a symmetrical line, separately. The adsorbing and carryingmechanism can adsorb LCD screens and separating cotton of different sizes and the LCD screens, the separating cotton, the empty cases and the full cases are symmetrically arranged along the same symmetrical line. The LCD screens change in size but the symmetrical line is not changed in position. The equipment can be used for classified packaging of the LCD screens of different grades.

Description

technical field [0001] The invention relates to the field of packaging equipment for display screens, in particular to an automatic grade classification packing equipment for LCD screens. Background technique [0002] Various processes are involved in the production of LCD screens. In the packaging process, it is necessary to absorb different grades of LCD screens from the screen conveying line, and classify and transfer them to packing boxes according to their grades, so as to proceed to the next step. Palletizing and warehousing, in the actual production of LCD screens, the handling manipulator, with the assistance of the CCD machine vision system, grabs the LCD screen and places the LCD screen in a packaging box. A box will contain multiple LCD screens of the same level. The two LCD screens are separated by cotton, and the boxes are transported out through the assembly line after they are filled. [0003] However, the LCD screens produced are of different grades, and the...

Problems solved by technology

[0003] However, the LCD screens produced are of different grades, and the LCD screens of different grades have different sizes. When the size of the LCD changes, the adsorption device on the manipulator also needs to be changed. After the adsorption device is changed, the alignment needs to be recalibrated, which is very time-consuming and laborious. If the size of the LCD screen is replaced by the adsorption and handling mechanism, the production efficiency will be reduced. If a production line is set up separately according to each size of the LCD screen, the cost will be increased and the space in the factory will be occupied.
