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

Embodiment
[0037]A feeding method for a backlight machine. When the feeding mechanism is started, the belt 11, the conveying plate 3, the endless belt 4 and the recovery belt 5 are started, and four telescopic rods 14 are started at the same time to alternately expand and contract to make the chain plate 13 swing in waves. , manually place the assembly side of the product on the endless belt 4 in a random direction, use the controller to control the suction and release of the suction nozzle 31, and control the suction nozzle 31 to suck when the suction nozzle 31 reaches the lowest point of the transfer tray 3 Products, when the suction nozzle 31 reaches the highest point of the conveying tray 3, control the suction nozzle 31 to release the product, the product falls into the guide seat 2, and then slides onto the belt 11, and the falling point of the product on the guide seat 2 is the highest point of the slope 21. point, and not the middle of the guide seat 2.

The invention provides a feeding mechanism of a backlight machine. The feeding mechanism comprises an operation table, a guiding base, a conveying disc and an annular belt; a belt is arranged on the surface of the operation table, wherein a baffle is arranged on one side of the belt, a correcting mechanism is arranged on the other side of the belt, and the guiding seat is arranged above the tail end of the belt; the annular belt is arranged on one side of the operation table, and the height of the annular belt is lower than that of the belt; the conveying disc comprises suction nozzles, a circular ring, supporting rods and a rotating shaft, and the conveying disc is obliquely arranged; bearings are uniformly arranged on the circular ring, the suction nozzles are connected with the bearings, the circular ring is fixedly connected with the rotating shaft through the supporting rods, and the rotating shaft is fixed on a machine frame of the backlight machine; and the higher end of the conveying disc is located above the guiding base, and the lower end of the conveying disc is located above the annular belt. According to the feeding mechanism and the feeding method of the backlight machine, vertical conveying of products is realized through the conveying disc which is obliquely arranged, the multiple suction nozzles arranged on the conveying disc are coordinated with the annular belt so that and the feeding mechanism can continuously circularly suck the products and convey the products to the guiding base, a large number of the products can be conveyed in a short time, and therefore the conveying efficiency is greatly improved.
Description
technical field [0001] The invention relates to the structure of a backlight machine, in particular to a feeding mechanism and a feeding method 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. The backlight module is mostly assembled by the backlight machine. The feeding system of the backlight machine is controlled by the general program of the backlight machine. There is a screen display at the assembly module of the backlight machine. When an abnormal situation occurs, the screen display will receive an error signal. The material automatically stops, and after the abnormal handling at the material loading place is completed, select to clear the error on the screen display, and then press the start button to continue the material loading operation. [0003] The feeding process...
