4. The backlight module production system of liquid crystal display device as claimed in claim 3,
the telescopic link includes outer pole and carriage release lever, the one end of outer pole and one of them connecting piece fixed connection, the other pot head of outer pole is established the carriage release lever, the carriage release lever is kept away from the one end and another of outer pole connecting piece fixed connection.
5. The system for producing a backlight unit of a liquid crystal display device as claimed in claim 4,
the backlight module production system of the liquid crystal display equipment further comprises a gluing component and an attaching component, wherein the gluing component is fixedly connected with the conveying belt, and the attaching component is arranged on the gluing component.
6. The system for producing a backlight unit of a liquid crystal display device as claimed in claim 5,
the rubber coating subassembly includes support, spreading machine, two locating parts and smears even roller, the support with conveyer belt fixed connection, the spreading machine sets up on the support, two the locating part all with support fixed connection, smear even roller's both ends and two the locating part rotates and connects, attached subassembly includes second motor, extension board, cylinder and sucking disc, the second motor is installed on the support, the output of second motor runs through the support, and with extension board fixed connection, the cylinder sets up the extension board with between the sucking disc.
7. A process for producing a backlight module of a liquid crystal display device, which adopts the backlight module production system of the liquid crystal display device as claimed in claim 6, comprising the steps of:
firstly, a back plate is placed on the conveyor belt, the dust removal device is started, and the dust removal device removes dust on the back plate;
the conveying belt conveys the back plate between the two middle plates, the first motor is started, the output end of the first motor drives the elliptical plate to rotate, the elliptical plate is matched with the first spring to drive the two connecting pieces to move, and the two connecting pieces drive the two middle plates to center and position the back plate;
then the conveying belt conveys the back plate to the lower part of the glue spreader, the glue spreader spreads the glue on the back plate, the two limiting parts limit the back plate and prevent the glue from flowing to the two sides of the back plate, and the even roller evenly spreads the glue on the back plate when the back plate passes through the even roller;
then the conveying belt conveys the back plate to the attaching assembly, the second motor is turned on, the output end of the second motor drives the support plate to rotate, the air cylinder drives the sucking disc to adsorb the light-emitting unit, and then the output end of the second motor drives the support plate to rotate to the position above the back plate so as to attach the light-emitting unit to the back plate;
and then the liquid flows out through the conveyor belt, so that the assembly of the backlight module is completed.
