Detailed Description

The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that the embodiments or technical features described below can be arbitrarily combined to form a new embodiment without conflict.

A fixing clamp 2 for a plate dividing machine is shown in figures 7-9 and comprises a fixing pressing block 24, a plurality of pressing strips 21 are arranged at the bottom of the fixing pressing block 24, the pressing strips 21 in the fixing pressing block 24 are hollowed out by taking the circle center of a light-emitting surface 14 as the middle point according to the pressing position of the pressing strips 21 in the process of fixing a substrate and the structure of a COB product, and the hollowing design can prevent the pressing strips 21 in the pressing blocks from pressing the light-emitting surface 14 and does not influence the plate dividing effect. Namely, the positioning groove 22 is arranged on the pressing bar 21, the positioning groove 22 takes the center of the circle of the light emitting surface 14 of the connected COB substrate as the middle point, and the diameter of the positioning groove 22 is larger than that of the light emitting surface 14. The design of the hollowed diameter is not strict, and preferably, the diameter of the positioning groove 22 is 4-6 mm larger than that of the light-emitting surface 14.

In one embodiment, the working principle of the board separator is as follows:

the first step is as follows: as shown in fig. 5, the COB continuous substrates 1 to be separated enter the apparatus track 6 from the material inlet 7 of the track 6, and after the COB continuous substrates 1 completely enter the track 6, as shown in fig. 4, the substrate fixing pressing block 24 of the separating apparatus is opened.

The second step is that: as shown in fig. 6, when the pushing device of the equipment rail 6 pushes the COB connecting piece substrates 1 to the tail end of the rail 6 along the limiting fixing groove 5, that is, the edge of the V-CUT line 12 in the COB connecting piece substrates 1 aligns with the tail end of the rail 6, the part of the substrate to be separated extends into the middle of the upper clamp 3 and the lower clamp 4 of the plate separator, and the pushing is stopped.

The third step: as shown in fig. 1, the substrate fixing press block 24 of the board separator is pressed downward, the edge of the COB connecting piece substrate 1 is provided with the margin 13, and the pressing strip 21 in the substrate fixing press block 24 of the board separator is pressed on the substrates at two sides of the hollow groove 11 of the COB connecting piece substrate 1 to fix the substrates. Preferably, the central axis of the positioning slot 22 does not coincide with the central axis of the fixed pressing block 24, in this embodiment, the length of the pressing strip 21 close to one side of the upper clamp 3 and the lower clamp 4 is smaller than the length of the pressing strip 21 far from one side of the upper clamp 3 and the lower clamp 4, so as to prevent the pressing strip 21 in the pressing block from pressing the light emitting surface 14. Preferably, a notch 23 is formed in one side, far away from the central axis of the positioning groove 22, of the bottom of the fixed pressing block 24, so that the pressing strip 21 in the pressing block is prevented from pressing the adjacent light-emitting surface 14, and the plate separating effect is not affected.

The fourth step: as shown in fig. 2-3, the upper clamp 3 and the lower clamp 4 of the board separator swing up and down simultaneously with the center of the V-CUT line 12 as the center. In this embodiment, the number of times of swinging is 6, and the angles are respectively: the swing times and angles are set according to the actual conditions of board separation, and the single COB product is separated from the connected substrate by 25 degrees, 30 degrees, 35 degrees, 40 degrees, 45 degrees and 50 degrees.

The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way; the utility model can be smoothly implemented by the ordinary technicians in the industry according to the drawings and the above description; however, those skilled in the art should understand that changes, modifications and variations made by the above-described technology can be made without departing from the scope of the present invention, and all such changes, modifications and variations are equivalent embodiments of the present invention; meanwhile, any changes, modifications, evolutions, etc. of the above embodiments, which are equivalent to the actual techniques of the present invention, still belong to the protection scope of the technical solution of the present invention.
