Description

Technical Field

[0001] The present invention relates to the technical field of LED packaging, and in particular to a device and method for filling LED packaging glue. Background Art

[0002] LED (semiconductor light emitting diode) packaging refers to the packaging of light-emitting chips, which is quite different from integrated circuit packaging. LED packaging not only requires protection of the wick, but also requires light transmission. Therefore, LED packaging has special requirements for packaging materials. The domestic LED packaging industry is currently relatively mature and has formed a complete LED packaging industry chain.

[0003] After the LED encapsulation glue filling device completes the filling, the uncured glue is in liquid or semi-liquid state, which is easy to flow and deform. This may cause the glue to overflow the encapsulation area and stain the surface of the LED product, causing defects in the product appearance. If the encapsulation glue is not cured before the subsequent process is carried out, the glue will continue to be in an unstable state during the subsequent handling, assembly and other operations. Once the glue shape changes, it may need to be re-encapsulated, which increases the probability of rework, thereby extending the production cycle and reducing production efficiency. Summary of the invention

[0004] The present invention discloses an LED packaging glue filling device and method, aiming to solve the technical problems in the background technology that if the LED packaging glue is not cured after filling, the glue is in liquid state and is easy to flow and deform, causing it to overflow and contaminate the surface of the product, affecting the appearance, and the subsequent processes are carried out before curing. During transportation and assembly, the glue is unstable and needs to be re-packaged if the shape changes, which increases the probability of rework, prolongs the cycle, and reduces efficiency.

[0009] By providing a glue curing component, when the LED packaging glue filling is completed, the telescopic electric rod starts to extend, driving the connecting plate to move downward, and the telescopic rod plays an auxiliary guiding role to ensure that the connecting plate descends smoothly. At the same time, the sliding rod slides downward in the limit seat to further ensure that the connecting plate moves vertically downward. As the connecting plate descends, the fixed rod drives the rotating rod to rotate around the circular rod, and the rear end of the rotating rod moves along the front end of the movable rod. At this time, the L-shaped plate is acted on by the upward elastic force of the compression spring, and a relative displacement is generated between the L-shaped plate and the connecting plate.

Since the rotating screw is movably connected to the fixing part, and the fixing part is fixed on the filling table, it provides support and positioning for the rotating screw. The inner side of the sliding seat is movably connected to the rotating screw and the auxiliary round rod. When the rotating screw rotates, according to the screw transmission principle, the sliding seat moves linearly on the rotating screw along the direction of the auxiliary round rod. The auxiliary round rod plays a guiding role to ensure that the sliding seat moves smoothly. During the movement of the sliding seat, the scraper connected to its top is The scraper moves step by step to scrape off the excess glue on the surface of the LED product after curing.

Cleaning up the excess glue can ensure that the product meets the designed size standards, which is conducive to subsequent assembly and use.

[0013] A method for using an LED packaging glue filling device, using the LED packaging glue filling device as described above, comprises the following steps:

[0014] Step 1: Place the LED products to be packaged on the conveyor belt driven by the electric rotating rollers on both sides of the filling table.
