Description

Technical Field

[0001] This invention relates to the field of conveying equipment technology, specifically to a backlight display module anti-damage conveying device. Background Technology

[0002] Backlight display modules are an important component of displays, widely used in LCD monitors. Their main function is to provide uniform backlighting. A backlight display module typically consists of a steel casing, a light source, and an optical film assembly.

The magnetic attraction method facilitates the quick positioning of the backlight display module, avoiding the traditional method of relying on manual handling of the backlight display module. Manual handling of the backlight display module is prone to squeezing damage to the optical film group on the backlight display module, and it is also easy to cause contamination and impurities to adhere to the optical film group on the backlight display module. The transfer is more standardized. With the help of the pressure plate 504, a uniform pushing force can be applied to the backlight display module when it is removed, avoiding damage caused by excessive local force; the hook 203 can be used to collect and transport the used protective shell 501, realizing the recycling of the shell. The number of shells used can be configured according to actual needs.

[0035] The working principle of this embodiment is as follows: First, the conveyor frame 101 is placed on the ground, and the drive motor 103 is started to drive the roller 104 to rotate, which in turn drives the conveyor belt 201. At this time, the positioning frame 2011 on the conveyor belt 201 is also conveyed. The blower supplies air pressure to the hollow cavity on the side of the air supply plate 102 through the hose, and the air pressure is discharged through the exhaust groove 1021. During the displacement of the conveyor belt 201, the sweeping mounting shell 301 and the exhaust groove 1021 are aligned and connected in real time. The limiting pressure plate 105 limits the protrusion 202 and the sweeping mounting shell 301, so that the conveyor belt 201 always fits the air supply plate 102. The air pressure is delivered to the exhaust pipe 304 through the sweeping mounting shell 301 and the air guide pipe 302. And discharge outwards; insert the backlight display module into the protective shell 501, and magnetic installation can be achieved by magnetically attracting the steel shell of the backlight display module through the magnet 502; the protective shell 501 can be held and inserted into the positioning frame 2011;

[0036] The air outlet groove above the exhaust pipe 304 is used to sweep and blow the backlight display module inside the protective housing 501 when the protective housing 501 is brought close to the positioning frame 2011. At the same time, the air outlet groove at the bottom of the exhaust pipe 304 will discharge from a row of through grooves at the bottom of the positioning frame 2011 on the same side, assisting in sweeping and blowing the conveyor belt 201 for cleaning. This sweeping and blowing method can achieve continuous air supply without affecting the continuous conveying of the conveyor belt 201. When the operator holds the protective housing 501 and inserts it into the positioning frame 2011, the control switch 402 will be squeezed on both sides of the housing, controlling the solenoid valve 303 on the same side to close, thereby stopping the supply of air pressure and preventing the protective housing 501 from falling out of the positioning frame 2011 due to the wind force. The control is simple.

[0037] When the protective shell 501 needs to be removed for transport, simply hold the handle on the protective shell 501 and remove it from the positioning frame 2011 to perform quality inspection and other tasks on the backlight display module. When the backlight display module needs to be disassembled, press down on the hand lever 505 to drive the lower pressure shaft 503 to push the lower pressure plate 504 down, compressing the spring on the lower pressure shaft 503, and then push out the backlight display module to detach from the magnet 502. After use, the protective shell 501 can be directly hung on the hook 203 below the conveyor belt 201 by the staff to realize the recycling and reuse of the shell.
