The LED block 1 is formed to have a size corresponding to the size of one LED substrate 60. Since the LED substrate 60 has a plurality of LEDs 61 mounted on its surface, the LED substrate 60 may be formed in various sizes according to the size and number of the LEDs 61. Accordingly, the LED block 1 may also be formed in various sizes according to the size of the LED substrate 60. However, the LED block 1 may have a size as small as possible so as to manufacture the cabinet 10 for an LED display device corresponding to the LED display device of various sizes and shapes.

The cabinet fixing jig 110 is formed to fix a plurality of LED blocks 1 at a predetermined interval, as shown in FIG. 6. On the bottom surface 111 of the cabinet fixing jig 110 shown in FIG. 6, 24 fixing protrusions 115 are provided in a 4×6 matrix shape so that 24 LED blocks 1 can be arranged in a 4×6 matrix shape.

Subsequently, a plurality of LED blocks 1 are disposed in the cabinet fixing jig 110 so as to be spaced apart from each other by a predetermined interval. When the opening 2 of the LED block 1 is inserted into the fixing protrusion 115 of the cabinet fixing jig 110, the LED block 1 is fixed. In the cabinet fixing jig 110 shown in FIG. 6, 24 LED blocks 1 may be arranged in a 4X6 matrix shape. Then, a cross (+)-shaped gap G is formed between the 24 LED blocks 1 fixed to the cabinet fixing jig 110.

Next, the binder 20 is injected into the gap G between the plurality of LED blocks 1 fixed to the cabinet fixing jig 110 using the 3D printer 120. For example, when the binder 20 is discharged while moving the nozzle 123 along the gap G between the plurality of LED blocks 1 with the traveling device 121 of the 3D printer 120, the nozzle 123 The binder 20 discharged from) is injected into the gap G between the plurality of LED blocks 1.

A plurality of control board fixing holes 33 for fixing the substrate may be formed. The power board and the control board are installed on the rear surface of the LED block 1 so as not to interfere with the LED board 60 installed on the front surface of the LED block 1. Accordingly, a plurality of power board fixing holes and a plurality of control board fixing holes may be formed on the rear surface of the LED block 1.

The plurality of power board fixing holes 32 and the plurality of control board fixing holes 33 have holes inside using the binder 20 discharged from the nozzle 123 in the same manner as the above-described LED board fixing holes 31. It can be formed with the protrusions (22, 23).
