Computer display assembly line
summary:
1. Automated conveying equipment
In the automated assembly line of computer display screens, double-speed chain conveyors, as the core conveying equipment, have become the core equipment in connection panel pretreatment, module assembly, final assembly inspection and other links with its characteristics of "precise positioning, flexible rhythm, and smooth transportation". Especially adapt to the transfer needs of high-precision and fragile parts such as displays. a. Panel pretreatment: precise transfer of glass substrates The cleaned and laser-cut glass substrate (only 0.5-1.1mm thick and easy to break) needs to be transported to the splitting table through a double-speed chain. The tooling board is made of anti-static acrylic material (surface resistance 10-10 Ω) to prevent static electricity from penetrating the panel circuit; during the transportation process, the speed of the double-speed chain is controlled by a servo motor (adjustable from 0.5-1m/min), and cooperates with the station stopper. Achieve precise pause (positioning error ≤±0.1mm), ensuring accurate alignment when the robot arm grasps the panel and reducing edge bumps. b. Backlight module assembly: Simultaneous connection of multiple processes After the light guide plate and the optical film are bonded, the double-speed chain transfers the semi-finished product to the LED light bar welding station. Because the laminating and welding processes take different times (laminating takes 15 seconds and welding takes 8 seconds), the double-speed chain supports "independent start and stop of stations". After the previous workstation is completed, the sensor signal triggers the subsequent transportation to avoid module accumulation or waiting. c. Final assembly: Carry the complete machine to complete multi-step integration After the panel and the backlight module are pressed together, the double-speed chain drives the whole machine through driving plate connection, shell assembly, screw tightening and other stations in turn. The load bearing of the tooling plate is designed to reach 30kg (meeting the weight of 27-inch display + fixture), and the chain is made of high-strength carburized carbon steel (tensile strength ≥800MPa) to ensure no deformation during long-term operation. d. Inspection link: stable support optical test At the display effect calibration station, the double-speed chain sends the display to the bottom of the color analyzer, and the mechanical lifting mechanism lifts the tooling plate by 5mm (away from the chain) to avoid the conveying vibration from affecting the detection accuracy of the luminometer (ensure that the reading error is ≤1cd/m2); After the test is completed, the qualified products are sent to the packaging area by the double-speed chain, and the unqualified products are diverted to the repair line through the side push mechanism. The diversion action is seamlessly connected with the chain operation (switching time ≤1 second).
2. Core advantages of computer display assembly line
a. Flexible production capacity：The double-speed chain track is adjustable (300-600mm width is adapted to 19-32-inch screens), realizing mixed-line production of different types of display screens such as LCD, OLED, Mini LED, etc., and the replacement time is shortened from manual line 4 hours to 15 minutes, making it easy to cope with personalized needs such as curved screens and full screens. b. Optimize comprehensive costs：For full-process automation equipment, only 8-10 operators are needed for a single line, the production capacity fluctuation error is ≤3%, and the production cycle efficiency is increased by more than 60%, which greatly reduces process jams caused by manual handling and waiting., can stably meet the needs of global customers for large quantities of orders.
