Abstract
Description
Technical Field

[0002] LCM displays are assemblies that combine liquid crystal display devices, connectors, peripheral circuits such as control and drive components, PCB circuit boards, backlights, and structural components. They are lightweight, thin, and consume little power, making them suitable for displaying various devices. In the production process of LCM displays, existing mixed liquid crystals are filled into the display area of the array substrate, then a border adhesive is applied to the display area of the color filter substrate. Finally, the array substrate and the color filter substrate are pressed together in a vacuum environment, and the mixed liquid crystals fill the display area to form a display cell.
[0003] In the existing technology, after a set of substrates is filled, the filling gun head will rise and wait for the next substrate to enter directly below the filling gun head. The liquid crystal filling liquid remaining inside the filling gun head will drip down. The dripping mixed liquid crystal may drip onto other areas of the substrate, making it difficult to scrape the already filled display module. This needs to be improved.

When the bonding plate 73 retracts, it can drive the first displacement plate 75 to retract inward, so that the first toothed plate 752 drives the reversing wheel 712 to rotate, so that the reversing wheel 712 drives the second toothed plate 782 to move, so that the first scraping plate 761 and the second scraping plate 791 move closer to each other at the same time, so as to perform scraping operation on the top edge of the filled display module, and can perform scraping operation on the open annular surface of the top edge of the filled display module.
[0090] Secondly, when the first scraping plate 761 and the second scraping plate 791 move to their limit positions, the first scraping pad 762 and the second scraping pad 792 seal the scraped display module to prevent the liquid crystal effluent in the filling member 5 from flowing into the scraped display module.
[0091] In some embodiments, in order to form a sealed area when the first scraping pad 762 is in contact with the second scraping pad 792, the size of the first scraping pad 762 is adapted to the size of the first scraping plate 761, and the size of the second scraping pad 792 is adapted to the size of the second scraping plate 791.

[0093] Another technical problem to be solved by the present invention is a method for using an automated liquid crystal filling device for an LCM display module.
[0094] S1. Conveying and gripping the display modules to be filled: Place multiple sets of display modules to be filled on the first belt conveyor 2, start the first belt conveyor 2 to convey the multiple sets of display modules to be filled, and start the first robotic arm 3 to grip the display modules to be filled onto the positioning and bearing member 6.
[0095] S2. Positioning operation of the display module to be filled: Activate the first electric cylinder 62 and the second electric cylinder 66 so that the output end of the first electric cylinder 62 and the output end of the second electric cylinder 66 are output to perform positioning operation of the display module to be filled on the second connecting substrate 61.
[0096] S3. Adjustment of the filling component 5 as a whole: Turn on the switches of the first electric cylinder 62 and the second electric cylinder 66 so that the output ends of the first electric cylinder 62 and the second electric cylinder 66 output to position the display module to be filled on the second connecting substrate 61.
[0097] S4. Filling operation of the display module to be filled: Turn on the third drive motor 52 so that the output end of the third drive motor 52 outputs to adjust the vertical position of the filling gun 57; then, turn on the filling gun 57 so that the output end of the filling gun 57 outputs to fill the display module to be filled in the positioning support member 6. When the filling gun 57 releases liquid crystal, it can be polymerized through the sealing ring 591 to enhance the filling effect of the liquid crystal.
[0098] S5. Perform a scraping operation to remove liquid crystal effluent from the filled display module: Activate the third electric cylinder 72 so that the output end of the third electric cylinder 72 outputs to stretch the bonding plate 73 to move, thereby driving the first scraping plate 761 and the second scraping plate 791 to move closer to each other simultaneously, for scraping the top edge of the filled display module; after the first scraping plate 761 and the second scraping plate 791 move to their limit positions, the first scraping pad 762 and the second scraping pad 792 seal the scraped display module to prevent the liquid crystal effluent in the filling member 5 from flowing into the scraped display module and affecting the scraped display module;
[0099] S6. Scraping operation of filling gun 57: While the scraping and cleaning component 7 scrapes the filled display module, the filling gun 57 can also be scraped by the moving gun nozzle cotton plate 764 to prevent liquid crystal effluent from dripping into the filled display module and to prevent liquid crystal effluent from forming beads at the tail of the filling gun 57.
[0100] S7. Grab and transfer the filled display module: Start the second belt conveyor 8 to grab the filled display module and place it on the second robot arm 9 to complete the transfer operation of the filled display module.
[0101] In summary, the positioning and supporting member 6 activates the first electric cylinder 62 and the second electric cylinder 66, causing their outputs to be used to position the display module to be filled on the second connecting substrate 61. The filling member 5 activates the third drive motor 52, causing its output to be used to adjust the vertical position of the filling gun 57. Subsequently, the filling gun 57 is activated, causing its output to be used to fill the display module to be filled within the positioning and supporting member 6. When the filling gun 57 releases liquid crystal, it can be polymerized by the sealing ring 591 to enhance the filling effect. The scraping and cleaning member 7 activates the third electric cylinder 72, allowing the third... The output of the electric cylinder 72 is used to stretch and move the bonding plate 73, thereby driving the first scraping plate 761 and the second scraping plate 791 to move closer to each other simultaneously, for scraping the top edge of the filled display module. When the first scraping plate 761 and the second scraping plate 791 move to their limit positions, the first scraping pad 762 and the second scraping pad 792 seal the scraped display module to prevent the liquid crystal effluent in the filling member 5 from flowing into the scraped display module and affecting it. While the scraping and cleaning member 7 is scraping the filled display module, the filling gun 57 can also be scraped by the moving gun nozzle cotton plate 764 to prevent the liquid crystal effluent from dripping into the filled display module and to prevent the liquid crystal effluent from forming beads at the tail of the filling gun 57.
