Abstract
Description
Technical Field

[0002] LED display screens use different materials to create LED pixels of different colors to display text, graphics, images, animations, market information, videos, video signals and other information. LED display screens are widely used in stations, shopping malls, hospitals, hotels, banks, industrial enterprise management and other public places. They can be used not only in indoor environments, but also in outdoor environments. They have advantages that projectors, TV walls and LCD screens cannot match.
[0003] Through the automatic loading system, the raw materials are transported to the designated position of the production line, ready for subsequent processing. The LED chips, driver chips and other electronic components are accurately mounted on the circuit board using a high-precision automatic placement machine. After the placement is completed, the automatic welding equipment will weld the components on the circuit board. The circuit board, power supply, casing and other components are assembled into a complete LED display screen through automated equipment.
[0004] After soldering the circuit boards, it is often necessary to apply protective paint or glue on them to enhance the moisture and dust resistance of the display. However, manual dispensing is difficult to control in terms of dispensing amount, dispensing position and dispensing speed, and it is difficult to achieve high precision. In addition, the lack of an intermittent mechanism on the conveyor belt causes uneven and inaccurate dispensing. When the circuit boards encounter dust during transportation, these tiny dust particles may become an obstacle, causing the gap between the dispensing needle and the product surface to change, thereby affecting the overall quality and appearance of the product.
