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.

[0036] Embodiment 1:

[0037] like Figure 1 , Figure 2 As shown, this embodiment discloses a raindrop pattern color-coated aluminum plate, including an aluminum plate body 1, the aluminum plate body 1 is a rectangular parallelepiped structure, the aluminum plate body 1 has an I-shaped cross section, and the aluminum plate body 1 includes two end faces 11 arranged opposite to each other up and down and two end faces 12 arranged opposite to each other left and right. The end faces 11 and 12 are both covered with a film layer 2, the film layer 2 is a raindrop pattern color coating film, and the film layer 2 is bonded to the end faces 11 and 12 by glue.

[0038] like Figure 2 As shown, the aluminum plate body 1 is provided with a groove body 121, which is recessed toward the inner side of the aluminum plate body 1 along the end face 12, and the length direction of the groove body 121 runs through the aluminum plate body 1. The groove body 121 includes a wall surface 1211 and a wall surface 1212, the wall surface 1212 is perpendicular to the end face 12, the two wall surfaces 1212 are arranged face to face up and down, the wall surface 1211 is located on the side of the wall surface 1212 away from the end face 12, the wall surface 1211 is parallel to the end face 12, and the wall surface 1211 is located between the two wall surfaces 1212.

[0039] Two membrane layers 2 are symmetrically arranged along the symmetry lines of the two end surfaces 11, and the membrane layers 2 cover the inner wall surface of the groove body 121. The membrane layer 2 includes a bending portion 21 located at the end, the bending portion 21 is perpendicular to the wall surface 1211, and the bending portion 21 extends to the side away from the wall surface 1211. The bending portions 21 of the two membrane layers 2 are attached to the groove body 121 from top to bottom.

[0040] like Figure 2 As shown, the raindrop pattern color-coated aluminum plate also includes a plug plate 3, which is inserted into the groove body 121. Specifically, the plug plate 3 includes a plug plate 1 31 and a plug plate 2 32, and the plug plate 2 32 is inserted into the groove body 121. The plug plate 2 32 is a rectangular rod-shaped structure, and the plug plate 2 32 is made of elastic plastic material. The plug plate 2 32 is provided with a groove body 2 322, and the bending parts 1 21 of the two film layers 2 are inserted into the groove body 2 322. The outer wall surface of the plug plate 2 32 is in contact with the wall surface 1 1211 and the wall surface 2 1212.

[0041] The plug plate 2 32 is also provided with a groove body 4 321, which is located on both sides of the groove body 2 322, and the groove body 4 321 is located between the bending portion 1 21 and the wall surface 2 1212.

The protrusion 311 is inserted into and expands the groove body 4 321, so that the inner wall of the groove body 2 322 presses the two bending portions 1 21 tightly. At the same time, since the protrusion 311 opens the groove body four 321, the outer wall surface of the plug plate two 32 is pressed against the wall surface one 1211 and the wall surface two 1212, so that the film layer 2 between the outer wall surface of the plug plate two 32 and the wall surface one 1211 and the wall surface two 1212 is pressed, thereby achieving the purpose of preventing the film layer 2 from falling off.

[0042] Embodiment 2:

[0043] like Figure 3-Figure 12 As shown, a production process of a raindrop pattern color-coated aluminum plate is used to process the raindrop pattern color-coated aluminum plate of Example 1.

[0044] like Figure 3 , Figure 4 As shown, it includes a base 4, the base 4 includes a boss 41 located at the top, and a positioning groove 411 is provided on the top of the boss 41. The positioning groove 411 is used to place and position the aluminum plate body 1.

[0045] like Figure 3 , Figure 4 As shown, it includes a moving block 51, which is located on the left and right sides of the base 4. The moving block 51 can be moved left and right by being driven by a driving component 5. The moving block 51 includes a moving plate 511, which is located below the boss 41, and the upper plate surface of the moving plate 511 is set along a horizontal plane.

[0046] like Figure 3 , Figure 4 As shown, it includes a pressing plate 61, which is located on the left and right sides of the base 4. The pressing plate 61 can be moved left and right by the driving component 2 6, and the pressing plate 61 is located outside the boss 41. The bottom surface of the pressing plate 61 is at the same height as the top surface of the moving plate 1 511.

[0047] like Figure 3 , Figure 4 As shown, it includes a bending assembly 7, which is located on the left and right sides of the base 4. The bending assembly 7 includes a moving block 2 71 and a cylinder driving the moving block 2 71 to move left and right. The moving block 2 71 includes a moving plate 2 711, and the moving plate 2 711 can extend into the slot 1 121. The upper end of the moving plate 2 711 is slidably connected with a limit plate 72, and the limit plate 72 is connected with a rod body 73, and the rod body 73 is slidably connected and inserted into the moving block 2 71. A spring 1 74 is arranged between the limit plate 72 and the moving block 2 71, and the two ends of the spring 1 74 abut against the limit plate 72 and the moving block 2 71 respectively.

[0048] The specific processing steps are:

[0049] ① Insert the aluminum plate body 1 into the positioning groove 411.

[0050] ② If Figure 3 , Figure 4 As shown, the two sides of the film layer 2 are bent to form a second bending portion 22, the film layer 2 is inserted into the aluminum plate body 1, the bottom surface of the film layer 2 is attached to the end surface 11, and the second bending portion 22 is attached to the end surface 12. Before the film layer 2 is attached to the surface of the aluminum plate body 1, the aluminum plate body 1 is coated with glue.

[0051] ③ Such as Figure 5 As shown, the pressing plate 61 extends toward one side of the boss 41, the pressing plate 61 and the boss 41 press the film layer 2, and the moving plate 1 511 extends toward the side close to the pressing plate 61, so that the bending portion 22 is bent to form the bending portion 1 21;

[0052] ④ Such as Figure 6 , Figure 7 As shown, the pressure plate 61 moves away from the boss 41, the movable plate 511 moves away from the pressure plate 61, the movable block 71 moves toward the end surface 12, and the movable plate 711 extends into the groove body 121 to bend the bending portion 22, so that the film layer 2 fits the wall of the groove body 121.

[0053] When the movable plate 2 711 extends into the groove body 121, the pressure cover 8 is pressed down so that the film layer 2 is pressed up and down by the pressure cover 8 and the end face 11, and the limiting plate 72 abuts against the end face 2 12 so that the limiting plate 72 and the end face 2 12 press the bending part 22, thereby making the film layer 2 fit more closely with the wall surface of the aluminum plate body 1.

[0054] ⑤ Invert the aluminum plate body 1, insert one side of the aluminum plate body 1 to which the film layer 2 is adhered into the positioning groove 411, and repeat steps ②③④ to make both film layers 2 adhere to the aluminum plate body 1.

[0055] ⑥ Insert the plug plate 2 32 into the groove body 121, insert the bent portion 1 21 into the groove body 2 322, and insert the plug plate 1 31 into the plug plate 2 32, so that the protrusion 311 is inserted into and opens the groove body 4 321, so that the inner wall of the groove body 2 322 presses the two bent portions 1 21. At the same time, because the protrusion 311 opens the groove body 4 321, the outer wall surface of the plug plate 2 32 presses the wall surface 1 1211 and the wall surface 2 1212, so that the film layer 2 between the outer wall surface of the plug plate 2 32 and the wall surface 1 1211 and the wall surface 2 1212 is pressed, thereby achieving the purpose of preventing the film layer 2 from falling off.

[0056] like Figure 10-12 As shown, when the bending portion 1 21 is inserted into the groove body 2 322 , the two are not easy to align, and insertion is likely to be difficult, so an auxiliary tool rod 9 is used. Fig.12 In the embodiment, the inner wall of the sleeve rod 9 is slidably connected with a slide bar 91, which is in the shape of a long strip and has a length greater than that of the slot body 121. The inner wall of the slide bar 91 is slidably connected with a limit rod 92. Specifically, the limit rod 92 includes a convex ring 921, the outer diameter of which is greater than that of the limit rod 92. The two sides of the slide bar 91 are provided with slot bodies 3 911, the convex ring 921 is inserted into the slot bodies 3 911 and slidably connected, and the side of the limit rod 92 away from the convex ring 921 passes through the slide bar 91 and is fixed to the sleeve rod 9. The limit rod 92 is sleeved with a spring 2 93, which abuts against the outer wall of the slide bar 91 and the inner wall of the sleeve rod 9, respectively.

[0057] Insert the two sleeve rods 9 into the groove body 121. When inserting, the slide rod 91 and the sleeve rod 9 shrink and approach each other, and the spring 2 93 is compressed. After insertion, the two slide rods 91 extend in under the action of their respective springs 2 93, and the two slide rods 91 press the bending parts 1 21 on both sides. At the same time, the end surface of the sleeve rod 9 abuts against the wall 2 1212, so that the position of the bending part 1 21 can just meet the groove body 2 322 of the plug plate 2 32, so as to facilitate the alignment of the bending part 1 21 and the insertion of the groove body 2 322. After the bending part 1 21 is initially inserted into the groove body 2 322, take out the two sleeve rods 9, and then install the plug plate 2 32 in place.

[0058] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. 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.
