[0030] The present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: Example 1

[0031] See also Figure 1-Figure 2, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments: an aluminum plate 5, with holes 51 formed on the aluminum plate 5, one end of an optical fiber 52 being fixed in each hole 51, a transparent curing coating being provided on the upper end surface of the aluminum plate 5, and one end of the optical fiber 52 being also fixed in the hole 51 through the transparent curing coating, a light source irradiates the front of the aluminum plate 5, irradiates one end of the optical fiber 52 located in the hole 51, then enters the optical fiber 52, and is emitted from the other end of the optical fiber 52, and then after the aluminum plate is loaded on the facade of the building, sunlight is introduced into the room through the optical fiber 52, providing light energy for the room, and at the same time can be reversed to display the light energy in the room on the aluminum plate 5. Example 2

[0032] This embodiment makes the following further improvements on the basis of embodiment 1, see Figure 1-Figure 6 : A surface treatment method and equipment for an aluminum plate. The aluminum plate needs to be pre-treated. After the aluminum plate is bent and welded, it is positioned by the bent edge, and a laser is used to drill holes on the surface of the aluminum plate. After the drilling is completed, a cleaning operation is performed to clean the surface of the aluminum plate.

[0033] After the pre-processing work is completed, the aluminum plate that has been pre-processed is placed on one side of the equipment.

[0034] The equipment includes a spraying station 1, a spraying unit 2 and a processing unit 3. The spraying station 1 is provided with a wire supply hole 11 adapted to the hole on the aluminum plate. The aluminum plate is positioned and buckled on the spraying station 1 by a robot. The positioning method here is consistent with the positioning of the bending edge during drilling, so that the hole on the aluminum plate is aligned with the wire supply hole 11. The spraying station 1 is provided with a negative pressure adsorption port. After the robot places the aluminum plate on the spraying station 1, the adsorption port adsorbs and fixes the aluminum plate on the spraying station 1.

[0035] A wire supply unit is arranged in the wire supply hole 11, and the wire supply unit is a roller friction type wire supply, that is, the roller is pressed on the optical fiber, and the roller rotates to carry the optical fiber and extend it upward along the wire supply hole 11. At the same time, the length of the wire delivery can be determined according to the number of circles of the roller rotation, and then the length of the optical fiber extension can be determined.

[0036] A detection unit is provided on the side wall at the upper end of the wire supply hole 11. The detection unit is a photoelectric switch. The optical fiber is made of opaque material. Therefore, the photoelectric switch is in a blocked state when the optical fiber is present. In the initial state, the wire supply unit supplies the wire upward, and one end of the optical fiber begins to move upward along the wire supply hole 11. When the optical fiber reaches the detection unit, the photoelectric switch is blocked, and the photoelectric switch controls the wire supply unit to stop supplying the wire. A detection unit is provided in each wire supply hole 11, so that the positions of one ends of the optical fibers in all the wire supply holes 11 can be basically consistent at the beginning, and the diameter of the hole on the aluminum plate is twice that of the optical fiber and is larger than the wire supply hole 11.

[0037] After the aluminum plate is adsorbed by the spraying station 1, the spraying station 1 first performs a self-check to see if each photoelectric switch is in a blocked state. After confirming that there is an optical fiber in each wire supply hole 11, the wire supply unit starts and the roller rotates a certain angle so that the upper end of the optical fiber is located in the hole of the aluminum plate. At this time, the wire supply unit stops supplying wires.

[0038] Track frames 4 are arranged on both sides of the spraying station 1. The spraying unit 2 and the processing unit 3 are both slidably arranged on the track frames 4 through a linear moving module. Through the linear moving module, the spraying unit 2 and the processing unit 3 can move freely on the track frames 4, including moving from one side of the aluminum plate to the other side. A spray head 21 is arranged on the spraying unit 2, and a UA lamp is arranged at the rear end of the spray head 21.

[0039] After one end of the optical fiber is inserted into the hole of the aluminum plate, the spray unit 2 starts to move on the track frame 4. During the movement, the spray head 21 sprays the UA curing coating on the upper end surface of the aluminum plate. The UA curing coating is fluid, and when spraying on the hole of the aluminum plate, the UA curing coating flows into the hole and fills the hole. A UA lamp is also provided on the spray unit 2. When spraying, the UA lamp is irradiated to quickly cure the UA curing coating, so that a layer of cured UA curing coating is formed on the surface of the aluminum plate. At the same time, the UA curing coating that flows into the hole also cures one end of the optical fiber in the hole, so that the optical fiber is cured and connected to the aluminum plate.

[0040] Since the UA cured coating at the holes flows into the holes, the UA cured coating on the surface of the aluminum plate is uneven. At the same time, due to the problem of line supply accuracy, one end of some optical fibers protrudes beyond the surface of the aluminum plate, so some optical fiber heads protrude beyond the cured layer, so the cured layer needs to be trimmed.

[0041] The UA cured coating is transparent, so it does not affect the introduction of light into the hole of the optical fiber.

[0042] The processing unit 3 includes a grinding roller 31, which is an inflatable grinding roller, that is, a flexible roller surface with abrasive grains attached to the roller surface. After the grinding roller 31 is inflated, the processing unit 3 moves along the track frame 4, and the roller surface elastically presses on the solidified layer on the surface of the aluminum plate. The grinding roller 31 rotates, and the solidified surface is polished and leveled during the movement of the processing unit 3. The processing unit 3 is also provided with a negative pressure dust suction device, and the negative pressure dust suction device 32 is arranged before and after the grinding roller 31. The dust suction work is continuously performed during the movement of the processing unit 3, thereby clearing the particles and dust during the grinding of the solidified layer, so that the solidified layer remains clean after the processing unit 3 passes.

[0043] A wiping sponge 33 is also provided at the front and rear ends of the processing unit 3. When the processing unit 3 moves back and forth, the surface of the solidified layer is polished to make the solidified layer flat, and the solidified surface is cleaned to keep the solidified surface clean.

[0044] At this time, the spraying unit 2 performs secondary spraying again, and then sprays a layer of transparent UA curing coating on the flat cured layer, and the UA lamp is used to cure it. After the secondary spraying and curing is completed, a layer of transparent UA curing coating is formed on the upper layer of the aluminum plate to protect the surface of the aluminum plate. At the same time, the optical fiber head is cured in the hole, making its UA curing coating transparent. Therefore, the optical fiber is irradiated on the aluminum plate, can enter one end of the optical fiber line, and be emitted from the other end of the optical fiber line.

[0045] A cutting device is also horizontally arranged in the spraying station 1. The cutting device is a cutting knife 12. A cutting cavity 13 is horizontally opened in the spraying station 1. The cutting cavity 13 is perpendicular to all the wire supply holes 11 and is located in the middle of the wire supply holes 11. The cutting knife is pulled by a hydraulic component or a starting component to move in the cutting cavity 13, and the passing optical fiber is cut off during the movement.

[0046] After the secondary spraying and curing of the aluminum plate surface is completed, the spraying unit 2 is reset, and the manipulator adsorbs the upper surface of the aluminum plate through the suction cup. At this time, the adsorption port on the spraying table 1 stops adsorption, and then the manipulator can lift the aluminum plate from the spraying table 1. During the lifting process, the wire supply unit works synchronously, and stops lifting after the manipulator is lifted to a certain height. At this time, the wire supply unit also stops working, and the cutting knife 12 starts to move to cut off the optical fiber lines in all the wire supply holes 11. At this time, the manipulator can remove the aluminum plate.

[0047] Surface treatment methods of aluminum plate: S1: The robot moves the cleaned aluminum plate placed on one side of the equipment to the spraying station 1 through the suction cup, and positions it, and the spraying station 1 absorbs and fixes the aluminum plate.

[0048] S2: The wire supply unit in the spraying station 1 works, and stops after delivering one end of the optical fiber to the detection unit position. After the optical fiber is delivered to the position, the wire supply unit works again to raise the optical fiber to a set height, that is, the upper end of the optical fiber is located in the hole of the aluminum plate.

[0049] S3: Spray the UA curing coating on the surface of the aluminum plate and irradiate it with a UA lamp to cure the UA curing coating and fix the optical fiber in the hole.

[0050] S4: The processing unit 3 processes the cured surface, flattens the cured surface and cleans the surface.

[0051] S5: Spray the aluminum plate with UA curing coating for the second time and use UA lamp to cure the coating at the same time.

[0052] S6: The robot lifts the aluminum plate upwards through the suction cup. During the lifting process, the wire supply unit works synchronously. After the robot is lifted to a certain height, it stops lifting and the wire supply unit also stops working. That is, after a certain length of optical fiber is reserved on the back of the aluminum plate, the cutting knife 12 starts to move and cuts off the optical fiber in all the wire supply holes 11. At this time, the robot can remove the aluminum plate.
