Defective material throwing device of automatic screen assembling machine

Abstract

The invention discloses a defective material throwing device of an automatic screen assembling machine. The defective material throwing device comprises a defective material throwing fixing plate fixed on the table surface of a crate, wherein a defective material throwing initiative fixing base and a defective material throwing passive fixing base are arranged at the front and back ends of the defective material throwing fixing plate respectively, a defective material throwing initiative wheel set and a defective material throwing passive wheel set are arranged on the defective material throwing initiative fixing base and the defective material throwing passive fixing base respectively; a defective material throwing profile belt sleeves between the defective material throwing initiative wheel set and the defective material throwing passive wheel set; the defective material throwing initiative wheel set is driven through a defective material throwing motor; a protection frame is arranged between the defective material throwing initiative fixing base and the defective material throwing passive fixing base; defective material throwing detection openings are formed in the front and back ends of the protection frame; detectors are arranged on the defective material throwing fixing plates, corresponding to the positions of the defective material throwing detection openings. The mechanism of the defective material throwing device is smart in structure, easy to manufacture, simple to operate, high in assembly precision and good in uniformity, the labor intensity of an operator is alleviated, the personal safety of the operator is guaranteed and the production efficiency is improved.

Description

technical field [0001] The invention relates to the field of screen assembly, in particular to a defective throwing device of an automatic screen assembly machine. Background technique [0002] The assembly process of the liquid crystal screen is complicated. The liquid crystal screen is equipped with multiple precision electronic devices, and a circuit board needs to be provided on the back of the liquid crystal screen. The circuit board is usually pasted on the back of the liquid crystal screen by adhesive. To ensure a firm paste, a certain amount of pressure needs to be applied to the board. The amount of pressure applied needs to be accurately controlled to avoid excessive pressure from damaging the electronic devices inside the LCD screen. At present, the screen assembly platforms used by many electronics manufacturers are mainly manual assembly by operators. The labor intensity of employees is high, the proportion of misoperation is relatively high, and the assembly...

AI Technical Summary

Problems solved by technology

At present, the screen assembly platforms used by many electronics manufacturers are mainly manual assembly by operators. The labor intensity of employees is high, the proportion of misoperation is relatively high, and the assembly consistency and accuracy are not high, and the efficiency is low. Especially in the mass production stage, the above shortcomings more obvious

In addition, manual assembly by operators takes a long time and is inefficient, making it difficult to meet the needs of mass production
