Shaking prevention charging mechanism of backlight machine

Abstract

The invention provides a shaking prevention charging mechanism of a backlight machine. The shaking prevention charging mechanism comprises a circulation belt, a conveying belt, suction nozzle structures, a correcting mechanism and an operating table; the correcting mechanism is located on the operating table; the circulation belt is annular; the conveying belt is in a ring-shaped straight edge ellipse shape; the suction nozzle structures are uniformly arranged at the lower part of the conveying belt; each suction nozzle structure comprises a suction nozzle, a guide rod, a metal sleeve and a fixing housing; the fixing housings are connected with the conveying belt; the suction nozzles are connected with the lower ends of the guide rods; the metal sleeves are arranged on the guide rods; andthe guide rods are in sliding fit with the fixing housings. Products are sucked circularly through the multiple suction nozzles arranged on the conveying belt, so that the charging efficiency is improved substantially; the guide rods of the suction nozzle structures can slide and can substantially buffer and suck inertia of the products, and the situation that the products are damaged or drop offdue to the fact that the guide rods quickly slide down after the guide rods slide to the highest points can be avoided through damping gears; and the metal sleeves have certain weight, so that the situation that the guide rods cannot slide down due to lack of weight can be avoided.

Description

technical field [0001] The invention relates to the structure of a backlight machine, in particular to an anti-shake feeding mechanism of the backlight machine. Background technique [0002] The backlight module is one of the key components of the LCD panel. Its function is to supply sufficient brightness and evenly distributed light source so that it can display images normally. Backlight modules are mostly assembled by backlight machines, and suction nozzles are often used to pick up products or mechanical claws to grab products during the feeding process of backlight machines. When the suction nozzle is used to suck the product, the suction and release of the suction nozzle is controlled by the controller. The principle is to start the vacuum pipeline instantly, so that the product at the suction nozzle moves up quickly and hits the suction nozzle to complete the suction of the product. During this process, due to the product It still has a high speed before touching the...

Problems solved by technology

Authorization number CN205820444U discloses an automatic feeding device for backlight film, which can transport products vertically through a vertical guide mechanism, but its structure is complex, it is highly dependent on servo motors, and its production cost is high

Authorization number CN205868825U discloses an automatic feeding detection system for backlight modules, which uses multiple servo motors at the same time, uses mechanical claws to grab products for transportation, and uses a correction plate to perform single-time calibration of products. There is some damage to the product when it is taken out, and the calibration board is only equipped with a single calibration, and the calibration effect is poor

[0005] Authorization number CN205916730U discloses a backlight feeding mechanism, which uses a single calibration device to calibrate the product. In actual use, the calibration effect is not ideal, and most products have not been accurately calibrated. If multiple calibration devices are used to correct a single product Continuous calibration can satisfy a better calibration effect, but it is necessary to prevent the product from colliding with the calibration baffle in front. At this time, an expensive servo motor is still required; and the product needs to be manually calibrated before calibration, otherwise the calibration baffle will be damaged. Crushing the product placed horizontally still requires a lot of manpower
