Detailed Description
In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein, but rather construed as limited to the embodiments set forth herein.
The following describes an embodiment of the flexible solar member in detail based on the printing method of the flexible solar member provided by the present invention. In the following description, the respective steps of the method will be explained in detail. Fig. 1 is a flowchart illustrating a printing method of a flexible solar component according to an embodiment of the present invention.
Step S101, providing magnetic transparent ink to be printed and providing magnetic materials.
In the embodiment of the invention, in order to improve the printing effect of the flexible solar component, firstly, a magnetic transparent ink material and a magnetic material are obtained. The magnetic transparent ink material at least needs to be added with transparent ink and pearl powder pigment. The transparent ink is made of high-transparency resin materials such as epoxy, polyurethane, organic silicon and the like, and the light transmittance of a finished product can be ensured by adding a proper amount of transparent ink, so that the influence on the light power generation efficiency is reduced. Before adding the pearl essence pigment, ferroferric oxide is needed to be pretreated, so that the treated pearl essence has magnetism. The flexible solar component is a flexible material of the flexible solar module, and the flexible material may be an outer protective film of the flexible solar module or a water blocking material in the flexible solar module. The magnetic material can be a deformable metal coil with magnetism when being electrified, and can also be a magnetic substance with magnetism, such as: magnets, and the like.
Step S102, arranging the magnetic material according to a predetermined pattern shape.
In the embodiment of the present invention, if a predetermined pattern meeting the customer requirements is to be printed, the magnetic material needs to be arranged first, and there are two arrangement methods for the magnetic material, one of which is a magnet arrangement method: when the magnetic material is a magnet, a preset magnetic material mold as shown in fig. 7 is obtained, a plurality of fixing grooves 701 for inserting a magnetic substance are tightly arranged in the magnetic material mold, the fixing grooves 701 may be slots or grooves, the magnet may be placed at a position corresponding to the fixing grooves 701 of the magnetic material mold according to a predetermined pattern shape, and finally a magnet arrangement pattern shape identical to the predetermined pattern shape is obtained, thereby completing the magnetic printing operation. The other method is an electromagnet method: when the magnetic material is a deformable metal coil with electrification and magnetism, the deformable metal coil is deformed according to a preset pattern shape, the metal coil arrangement pattern shape identical to the preset pattern shape is finally obtained, after electrification, the deformable metal coil is made to adsorb and penetrate the magnetic transparent ink material sprayed on the penetrating device 502 on the upper portion of the front plate made of the non-flexible material, and then the magnetic printing operation is completed.
Step S103, placing the flexible material of the pattern to be printed on the arranged magnetic material.
And S104, presetting a temperature range threshold, coating the magnetic transparent ink on the flexible material of the pattern to be printed, and adjusting the current temperature value according to the preset temperature range threshold so that the magnetic material is quickly condensed on the surface of the flexible material to form the printed pattern.
In the embodiment of the invention, before coating the magnetic transparent ink on the flexible material of the pattern to be printed, the flexible material is required to be cleaned and dried in a cold mode, then the magnetic material is arranged according to the preset shape, so that the magnetic absorption area is determined, the magnetic transparent ink is coated on the leakage device corresponding to the magnetic absorption area in a spraying or scraping mode, the magnetic transparent ink is kept standing for the preset time, and the magnetic transparent ink coated on the leakage device corresponding to the magnetic absorption area is absorbed on the flexible material by utilizing the magnetic absorption force of the magnetic material on the magnetic transparent ink. It should be noted that the flexible material is mainly composed of polyvinyl chloride, polyethylene, polypropylene, polystyrene, and other resins, and thus, the requirements on temperature and light during printing the flexible material are relatively high. Meanwhile, since the flexible material is easily wrinkled and uneven during printing, after the magnetic transparent ink is coated on the flexible material, it needs to be quickly coagulated to form a printed pattern to prevent the occurrence of impregnation. The magnetic absorption area is an area under the action of magnetic material magnetic adsorption force, and the leakage device is a silk screen or other permeable films and the like, wherein the silk screen or other permeable films can permeate the magnetic transparent printing ink under the action of the magnetic material magnetic adsorption force.
In the embodiment of the invention, the magnetic transparent ink on the flexible material is cured through a low-temperature curing process according to a preset temperature range threshold, wherein the low-temperature curing process is specifically that after the magnetic transparent ink is adsorbed onto the flexible material, the temperature value is rapidly reduced within a preset time threshold (for example, 5 to 10 seconds), for example, when the ambient temperature of the magnetic transparent ink in the magnetic adsorption process is 30 ℃, after the magnetic transparent ink is adsorbed onto the flexible material, the ambient temperature needs to be rapidly reduced to about 0 ℃ within a very short time threshold, so that the magnetic material is rapidly condensed on the surface of the flexible material of the pattern to be printed, and the printed pattern is formed. .
The invention discloses a printing method of a flexible solar component, which can print patterns in various forms according to requirements, is simple to operate and effectively improves the printing efficiency. The printing method provided by the invention is preferably suitable for printing flexible solar components, and can also be suitable for printing inflexible solar components after a fixing device consisting of a clamp or a screw is converted into a limiting device consisting of a limiting strip or a limiting clamping groove.

The flexible substrate solar module in the embodiment of the present invention refers to a flexible solar module fabricated on a flexible material (such as a polymer film, a polyester film, etc.).
Step S204, sequentially placing the flexible material, the first adhesive film material, the water blocking material, the second adhesive film material, the flexible substrate material, the third adhesive film material and the back plate material from top to bottom to form a laminated structure.

When the common adhesive film material is used, the first adhesive film material 401 is melted to adhere the upper layer flexible material 302 and the lower layer water-blocking material 407 according to a preset temperature threshold (120-. When the PVD adhesive film material is used, a preset temperature threshold needs to be set to (140-. The flexible material can be an outer protective film of the flexible solar cell module, a water-blocking material or a non-flexible solar front panel of the non-flexible solar module. The upper side of the flexible substrate material 408 is also provided with a deposition layer for depositing the photovoltaic material of the solar cell. After the mutually bonded layered structure is obtained, a flexible solar part is obtained by applying a certain pressure to the mutually bonded layered structure. It should be noted that the above bonding process is performed in a vacuum insulation laminator. Of course, the flexible material needs to be cleaned and dried again before the bonding process is performed.
