[0006] The present invention is further configured such that the length direction of the groove is arranged in the same direction as the length direction of the convex body, and the length of the groove is smaller than that of the convex body.

[0007] The present invention is further configured such that the protrusion passes through the sealing ring, and the inner peripheral wall surface of the sealing ring is in close contact with the outer peripheral wall surface of the protrusion.

[0008] The present invention is further configured such that the cushion layer is thermal insulation cotton.

[0009] The present invention is further configured such that the substrate further comprises an end face three on a side away from the end face one, and the end face three is flush with an end face of the insert plate on a side away from the end face one.

[0010] The present invention also adopts the following technical solution: a method for producing a D wood grain printed board, comprising the following production steps:

[0011] ① Install a sealing ring on the outer periphery of the bottom of the second tank;

[0012] ②Insert the plug-in board into the base plate, insert the protrusion into the second groove body, and make the inner wall of the sealing ring close to the outer wall of the protrusion to form a seal;

[0013] ③ Bond the cushion layer to the raised portion, with the top of the cushion layer extending beyond the end surface;

[0014] ④ After the end surface is coated with glue, the printed board layer is bonded, and the bottom surface of the printed board layer is bonded with the end surface. During the bonding process, the printed board layer presses the cushion layer, and the cushion layer is compressed;

[0015] ⑤ Insert pads on both sides of the trough body, and move the insert plate toward the end face three until the bottom plate is flush with the end face three, and the cushion layer rebounds to a free state.

When the excess glue cannot be squeezed out, it can be pressed into the groove, so that the entire printed board surface is flatter after molding. At the same time, since the cross-section of the convex body is an arc, the pressure difference on the two sides of the protrusion makes the protrusion have a tendency to shrink toward its arc circle, thereby reducing the occurrence of debonding between the two ends of the arc and the end face.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] like Figure 1 As shown, this embodiment discloses a 3D wood grain printing board, including a substrate 1 and a printing board layer 2, wherein the printing board layer 2 is a thin layer of aluminum plate. Figure 2 In the figure, the printing board layer 2 is located at the upper end of the substrate 1, and the printing board layer 2 includes a second end surface 22 located at the top, and the second end surface 22 is printed with 3D wood grain. A plurality of convex bodies 21 are arranged on the top of the printing board layer 2, and the cross section of the convex body 21 is arc-shaped, and the convex body 21 convexes upward along the second end surface 22, and the convex body 21 extends along the length direction of the second end surface 22 to form a long strip, and the convex body 21 is provided with a plurality of strips along the width direction of the second end surface 22, so that the wood grain on the second end surface 22 forms a more three-dimensional visual effect.

[0029] like Figure 2 As shown, a groove 211 is provided on the side of the printed board layer 2 away from the second end surface 22, and the groove 211 and the protrusion 21 are arranged correspondingly along the thickness direction of the printed board layer 2. Figure 2 In the figure, the groove 211 is located below the convex body 21, and the groove 211 extends upward along the bottom surface of the printing plate layer 2. The groove 211 is arranged one by one with the convex body 21, and the length direction of the groove 211 is arranged in the same direction as the length direction of the convex body 21. The length of the groove 211 is smaller than the convex body 21, and the two ends of the length direction of the groove 211 do not pass through the printing plate layer 2.

[0030] like Figure 2As shown, the substrate 1 includes an end face 12 at the upper end and an end face 3 13 at the lower end. The end face 12 is attached to and bonded to the bottom surface of the printed board layer 2. The substrate 1 is provided with a groove body 11, which is concave upward along the end face 3 13. The length direction of the groove body 11 is in the same direction as the length direction of the convex body 21. Both ends of the length direction of the groove body 11 pass through the substrate 1. The substrate 1 is also provided with a groove body 2 111, which is connected to the groove body 2 111, and is combined with the groove body 111. Figure 4 The groove body 11 includes a wall surface 112, which is the upper wall of the groove body 11. The groove body 111 extends upward along the groove body 11 and passes through the upper end of the substrate 1. The groove body 111 is connected to the groove 211. Figure 5 As shown, the second slot 111 is a rectangular slot.

[0031] like Figure 2 , Figure 3 , Figure 4 As shown, a sealing ring 6 is installed on the circumferential side wall of the second tank body 111 away from the groove 211. The sealing ring 6 is a rubber sealing ring and has a rectangular structure. Specifically, a sink groove is provided on the circumferential side wall of the second tank body 111, and the sealing ring 6 is inserted into the sink groove.

[0032] like Figure 2 As shown, a plug board 3 is installed on the side of the substrate 1 away from the printed board layer 2, the plug board 3 is inserted into the substrate 1, and the end face 3 13 is flush with the bottom surface of the plug board 3. Specifically, the plug board 3 includes a bottom plate 32 and a protrusion 31, the protrusion 31 protrudes upward and extends along the upper end of the bottom plate 32, the bottom plate 32 is inserted into the groove body 11, the protrusion 31 is inserted into the groove body 2 111, the protrusion 31 passes through the sealing ring 6, and the inner peripheral wall surface of the sealing ring 6 is tightly attached to the outer peripheral wall surface of the protrusion 31.

[0033] like Figure 2 As shown, a cushion layer 5 is installed on one side of the raised portion 31 close to the printed board layer 2, the bottom of the cushion layer 5 is bonded to the top of the raised portion 31, the cushion layer 5 is thermal insulation cotton, and plays a thermal insulation role, and the upper part of the cushion layer 5 is inserted into the groove 211 and fills the groove 211.

[0034] The groove body 11 is also inserted with a pad 4, which is located at both ends of the groove body 11 in the length direction. The groove body 11 includes a wall 112 located on the side close to the end face 12, and the plug plate 3 includes an end face 321 located at the upper end. The end faces on both sides of the pad 4 are respectively against the end face 321 and the wall 112.

[0035] The production method of the above 3D wood grain printed board comprises the following production steps:

[0036] ① A sealing ring 6 is installed on the outer periphery of the bottom of the second tank body 111.

[0037] ②Insert the plug board 3 from the bottom of the base plate 1, insert the bottom plate 32 into the groove body 11, insert the protrusion 31 into the groove body 2 111, the outer peripheral wall of the protrusion 31 fits with the circumferential wall of the groove body 2 111, and the inner peripheral wall of the sealing ring 6 fits tightly against the outer peripheral wall of the protrusion 31 to form a seal. Figure 4 , Figure 6 , the upper end surface of the bottom plate 32 (i.e., the end surface 321) is close to but not abutting against the upper wall surface of the trough body 11 (i.e., the wall surface 112). At this time, the lower end surface of the bottom plate 32 extends into the trough body 11.

[0038] ③ Bond the cushion layer 5 to the raised portion 31 , with the top of the cushion layer 5 extending out of the end surface 12 , and the height of the cushion layer 5 extending out of the end surface 12 being greater than the depth of the groove 211 .

[0039] ④ The end surface 12 is glued and bonded to the printed board layer 2, and the bottom surface of the printed board layer 2 is bonded to the end surface 12. During the bonding process, the bottom surface of the printed board layer 2 presses down the cushion layer 5. Since the cushion layer 5 is honeycomb-shaped inside, after the cushion layer 5 is squeezed by the printed board layer 2, part of the gas inside it is squeezed out from the upper end of the end surface 12, and the cushion layer 5 completely fills the groove 211. After the printed board layer 2 is bonded to the substrate 1, it needs to be leveled. Since the cushion layer 5 fills the groove 211, the cushion layer 5 supports the protrusion 21, so that the protrusion 21 can withstand a certain pressure and reduce the frequency of its deformation.

[0040] ⑤ If Figure 3 , Figure 4 As shown, the pad 4 is inserted into both sides of the groove body 11, and the end faces of the pad 4 on both sides are respectively against the end face 4 321 and the wall 112. During the insertion process, the pad 4 moves the plug 3 toward the end face 3 13 until the bottom plate 32 is flush with the end face 3 13. In this process, the spacing between the raised portion 31 and the printed board layer 2 increases, so that the cushion layer 5 that was originally squeezed expands and restores the free state (that is, the cushion layer 5 is in a state without pressure). Before the glue is completely cured, in order to prevent the glue from locally gathering and causing the printed board layer 2 to have local protrusions after curing, it is necessary to press the printed board layer 2 to make the glue evenly distributed and better bond the printed board layer 2 to the substrate 1. When pressing the printed board layer 2, since the internal air pressure of the cushion layer 5 is reduced after expansion, a pressure difference is generated on both sides of the raised portion 31, so that the printed board layer 2 and the substrate 1 are more closely combined to reduce the possibility that the printed board layer 2 and the substrate 1 are easily moved relative to each other. When the excess glue cannot be squeezed out, it can be pressed into the groove 211, so that the entire printed board layer 2 is flatter after molding. At the same time, since the cross-section of the protrusion 21 is arc-shaped, the two ends of the arc and the end face 12 are easy to debond. Through the pressure difference on the two sides of the protrusion 31, the protrusion 31 has a tendency to shrink toward its arc circle, thereby reducing the occurrence of debonding between the two ends of the arc and the end face 12.

All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
