In S1, the glue filling fixture 100 is fixed on the lamp board 50 before glue filling, and the lamp bead group 60 is arranged in the first grid unit 111, so that the first grid unit 111 blocks the lamp pins.

In S2, a first glue layer (not shown in the figure) is poured integrally between the lamp board 50 and the glue potting jig 100, so that the contact part of the glue potting jig 100 and the light board 50 is sealed to ensure the first grid The inside and outside of the unit 111 are mutually independent spaces. Specifically, it is ensured that the first grid unit 111 and the second grid unit 21 are mutually independent spaces.

In S3, the first glue layer is dried and cured, a second glue layer (not shown in the figure) is poured into the first grid unit 111 to cover the lamp pins, and a third glue layer is poured into the second grid unit 21 (in the figure). not shown).

In S4, after drying and curing the second glue layer and the third glue layer, the glue filling is completed.

Specifically, in S1 , the glue-potting fixture 100 is first placed on the lamp board 50 , so that each lamp bead group 60 falls into each of the first grid units 111 in a one-to-one correspondence.

Specifically, in S3, after the first glue layer is dried and solidified, glue is poured into the first grid unit 111 and the second grid unit 21 respectively to form the second glue layer and the third glue layer. The height of the second glue layer may be slightly greater than or substantially equal to the height of the lamp pin, and the height of the third glue layer may be smaller than the height of the second glue layer. Specifically, the height of the second glue layer may be determined according to the height of the lamp pins in the first grid unit 111 . The second glue layer can just cover the entire lamp pin, so as to play a waterproof and anti-corrosion effect on the lamp pin. The height of the third glue layer may be substantially equal to the height of the second grid unit 21 . The height of the second grid unit 21 is slightly higher than the height of the electronic components on the lamp board 50 . Therefore, the third glue layer can just cover the electronic components in the second grid unit 21 . For example, the height of the third glue layer is slightly higher than the height of the electronic components on the light board 50, so as to play the functions of waterproof and anti-corrosion to the electronic components. After the second glue layer and the third glue layer are both dried and solidified, the entire glue filling process is completed.

The glue potting fixture 100 in the above embodiment has at least the following advantages:

1) The heights of the lamp pins of different lamp boards 50 are different, and the spacing between the lamp beads of different lamp boards 50 is also different. Compared with the traditional glue filling jig, the present application separately fills the first grid unit 111 and the second grid unit 21 with glue, which greatly reduces the amount of glue, thereby achieving weight reduction and cost reduction. Specifically, according to different lamp bead heights and different lamp bead spacings, the amount of glue can be reduced to a different degree, and can be reduced by more than 80% at most;

2) In the modular design of the glue filling fixture 100, the weight of the glue filling fixture 100 module is limited. The first grid unit 111 and the second grid unit 21 are independently filled with glue, which can greatly reduce the weight of the entire display module during the use of the glue filling fixture 100;

3) The structure is simple and easy to operate, and it can be widely applied to lamp panels 50 of different structures, and has a wider application range.

The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity, all possible combinations of the technical features in the above-described embodiments are not described. However, as long as there is no contradiction between the combinations of these technical features, All should be regarded as the scope described in this specification.
