[0045] At present, phototherapy, as a method of treating the human body with light of a specific wavelength, has been widely used in the medical and cosmetic fields. Phototherapy can stimulate the energy metabolism of cells, improve cell vitality and function, improve skin condition, and reduce wrinkles, acne, spots and scars. It can also stimulate the production of collagen and elastic fibers and improve the firmness of the skin. Among them, phototherapy facial patches that can be applied to the face have been widely used.

[0046] In the related art, the phototherapy facial patch includes two parts: a control box and a patch. The control box includes a shell, a battery, a circuit board, etc. The patch includes a transparent outer layer, a light board, and an opaque outer layer, etc. The transparent outer layer, the opaque outer layer, the shell, etc. need to be manufactured by injection molding. After injection molding, they are assembled with batteries, circuit boards, light boards, etc. Therefore, multiple sets of injection molds are required. The number of molds is large and the structure is relatively complex. The mold processing cycle is long, which leads to an increase in the product production cycle and an increase in production costs.

[0047] Based on the above considerations, some embodiments of the present application provide a method for manufacturing a light therapy device 100, see Figures 1 to 8 The manufacturing method of the phototherapy device 100 comprises the following steps:

[0048] Material preparation step S10: preparing a forming mold 200 and a flexible light panel 110 for emitting light, wherein the forming mold 200 has a forming cavity.

[0049] The flexible light panel 110 can emit light having a phototherapy effect, see Figures 2 to 4The flexible light board 110 has a first surface 111 and a second surface 112 facing each other. The first surface 111 or the second surface 112 is provided with a light-emitting element 113, and the light-emitting element 113 is used to emit light with a phototherapy effect. A control element can be provided on the flexible light board 110, and the control element is in communication connection with the light-emitting element 113. The control element can control the time when the light-emitting element 113 emits light and the intensity of the emitted light. Among them, the light-emitting element 113 includes but is not limited to lamp posts, lamp beads and lamp tubes. Specifically, the light-emitting element 113 can adopt an LED lamp, which has the advantages of low power consumption, energy saving and high efficiency, can reduce the replacement frequency, and reduce maintenance costs.

[0050] A power supply element 114 can also be provided on the flexible light board 110, and the power supply element 114 can supply power to the flexible light board 110 so as to light up the light-emitting element 113 on the flexible light board 110. Optionally, the power supply element 114 can be provided on a surface opposite to the light-emitting element 113, for example, the light-emitting element 113 can be provided on the first surface 111 of the flexible light board 110, and the power supply element 114 is provided on the second surface 112, or the light-emitting element 113 can be provided on the second surface 112 of the flexible light board 110, and the power supply element 114 is provided on the first surface 111. Specifically, the power supply element 114 can be a button battery. For the convenience of description, the following description is based on the assumption that the power supply element 114 is provided on the first surface 111, and the light-emitting element 113 is provided on the second surface 112 of the flexible light board 110.

[0051] Material preparation step S20: preparing a transparent fluid material for wrapping the flexible light panel 110 .

[0052] The fluid material refers to a liquid used to form the coating structure 120 that wraps the flexible light board 110. The fluid material can be cured after heating to form a solid coating structure 120. The fluid material may include a material for providing light transmission performance to the coating structure 120, such as silica gel, etc.; the fluid material may also include a material for dissolving, such as water, etc.; the fluid material may also include a curing agent, such as hexamethylenetetramine, etc., so that the fluid material can form a solid coating structure 120. The fluid material may have a high viscosity so that the fluid material can better adhere to the surface of the flexible light board 110.

[0053] After the fluid material solidifies, a transparent coating structure 120 is formed. When the phototherapy device 100 is in use, the light emitted by the light-emitting element 113 can pass through the coating structure 120 and irradiate the user's skin, thereby playing a phototherapy role. In addition, the coating structure 120 makes the flexible light board 110 sealed, which can protect the electronic components such as the power supply element 114 and the light-emitting element 113 on the flexible light board 110.

[0054] The first encapsulation step S30 is to place the flexible light board 110 in the molding cavity and inject a fluid material to form a first encapsulation body 121 that encapsulates one side of the flexible light board 110 .

[0055] In this step, the fluid material can be automatically injected into the molding cavity through the injection structure. In some embodiments, the staff can operate the injection structure and inject the fluid material into the forming mold 200 through the injection structure. The injection structure can be an injection machine or other equipment; in other embodiments, an automatic injection device can be set, and through a program pre-set in the automatic injection device, the automatic injection device can automatically inject the fluid material into the forming mold 200 and control the amount of the fluid material injected.

[0056] The first encapsulating body 121 encapsulates one side of the flexible light panel 110 , that is, the first encapsulating body 121 may encapsulate the side where the first surface 111 is located or the side where the second surface 112 is located.

[0057] Secondary encapsulation step S40 : injecting fluid material into the molding cavity to form a second encapsulating body 122 encapsulating the other side of the flexible light panel 110 .

[0058] It can be understood that when the first encapsulating body 121 in step S30 covers the side where the first surface 111 is located, the second encapsulating body 122 formed in step S40 covers the side where the second surface 112 is located; when the first encapsulating body 121 in step S30 covers the side where the second surface 112 is located, the second encapsulating body 122 formed in step S40 covers the side where the first surface 111 is located. The first encapsulating body 121 and the second encapsulating body 122 are integrally formed to form the encapsulating structure 120, which wraps the flexible light board 110 and seals the flexible light board 110.

[0059] The manufacturing method of the phototherapy device 100 provided in the present application can coat the flexible light board 110 twice by injecting fluid material into the molding cavity where the flexible light board 110 is placed, and finally an integrally formed coating structure 120 that wraps the entire flexible light board 110 is formed. Only one mold is required, and the mold structure is simple and easy to process. The manufacturing time of the phototherapy device 100 can be greatly shortened, the production efficiency of the phototherapy device 100 can be improved, the production cost of the phototherapy device 100 can be reduced, and the integrity and consistency of the appearance of the phototherapy device 100 can be improved.

[0060] According to some embodiments of the present application, see Figures 5 to 8 , the molding cavity includes a first cavity 300 and a second cavity 400 that are spaced apart, and the primary coating step S30 includes:

[0061] In the first injection step S31 , the flexible light panel 110 is placed in the first cavity 300 , and a fluid material is injected into the first cavity 300 .

[0062] In this step, when the flexible light board 110 is placed in the first cavity 300, the flexible light board 110 can be placed in different states, that is, it may be a state where the first surface 111 is exposed, or it may be a state where the second surface 112 is exposed. If the first surface 111 of the flexible light board 110 is exposed in the first cavity 300, the liquid level of the fluid material entering the first cavity 300 will submerge the first surface 111, so that when the fluid material solidifies, a first encapsulation 121 covering the first surface 111 can be formed; similarly, if the second surface 112 of the flexible light board 110 is exposed in the first cavity 300, the liquid level of the fluid material entering the first cavity 300 will submerge the second surface 112, so that when the fluid material solidifies, a first encapsulation 121 covering the second surface 112 can be formed.

[0063] In the first heating step S32, the forming mold 200 is heated to a first preset temperature. Specifically, the heating can be performed by a mold temperature controller or the like.

[0064] Optionally, in this step, the first preset temperature is 65° C. to 88° C. Optionally, the first preset temperature is 80° C.

[0065] The first heat preservation step S33 is to keep the forming mold 200 warm for a first preset time. By heating and keeping the fluid material warm, the fluid material can be finally solidified into the first encapsulation body 121 .

[0066] Optionally, in this step, the first preset time is 1 min to 10 min. Optionally, the first preset time is 2 min.

[0067] It can be understood that in this step, the heating temperature and insulation time of the forming mold 200 can be flexibly set according to actual needs. For example, when the heating temperature is low, the insulation time can be extended to ensure the molding effect of the final product; conversely, when the heating temperature is high, the insulation time can be shortened to ensure the molding effect of the final product.

[0068] According to some embodiments of the present application, see Figures 5 to 8 The secondary coating step S40 includes:

[0069] In the second injection step S41 , the flexible lamp panel 110 and the first encapsulating body 121 are placed in the second cavity 400 , and a fluid material is injected into the second cavity 400 .

[0070] In this step, when the flexible light board 110 and the first covering body 121 are placed in the second cavity 400 as a whole, the surface of the flexible light board 110 not covered by the first covering body 121 will be exposed in the second cavity 400, so the liquid level of the fluid material entering the second cavity 400 will submerge the surface of the flexible light board 110 not covered by the first covering body 121, forming a second covering body 122.

[0071] The second heating step S42 is to heat the forming mold 200 to a second preset temperature. Specifically, the heating can be performed by a mold temperature controller or the like.

[0072] Optionally, in this step, the second preset temperature is 65° C. to 88° C. Optionally, the second preset temperature is 80° C.

[0073] The second heat preservation step S43 is to keep the forming mold 200 warm for a second preset time.

[0074] Optionally, in this step, the second preset time is 1 min to 10 min. Optionally, the second preset time is 2 min.

[0075] It can be understood that in this step, the heating temperature and insulation time of the forming mold 200 can be flexibly set according to actual needs. For example, when the heating temperature is low, the insulation time can be extended to ensure the molding effect of the final product; conversely, when the heating temperature is high, the insulation time can be shortened to ensure the molding effect of the final product.

[0076] By heating and keeping the fluid material warm in the second cavity 400, the fluid material can be finally solidified into the second coating 122. The second coating 122 is connected to the first coating 121 while being formed, thus avoiding gluing or suturing the structure. The process is reliable and stable and can adapt to automated operations. The manufactured phototherapy device 100 has a stable and reliable structure and a neat and beautiful appearance.

[0077] In some embodiments, see Figures 5 to 8 The forming mold 200 includes a lower mold 220 and an upper mold 210 cooperating with the lower mold 220, the upper mold 210 has a first groove 211, a second groove 212 and a glue inlet 213 connecting the first groove 211 and the second groove 212, the lower mold 220 has a third groove 221 for placing the flexible light board 110 and a fourth groove 222 for placing the flexible light board 110 and the first encapsulation body 121.

[0078] In the primary coating step S30 and the secondary coating step S40 , the upper mold 210 and the lower mold 220 can be stacked so that the first groove 211 connects with the third groove 221 to form a first cavity 300 , and the second groove 212 connects with the fourth groove 222 to form a second cavity 400 .

[0079] Taking the first encapsulating body 121 encapsulating the first surface 111 and the second encapsulating body 122 encapsulating the second surface 112 as an example, in step S30, the flexible light board 110 is placed in the third groove 221, and the second surface 112 of the flexible light board 110 is in contact with the bottom wall of the third groove 221. When the upper mold 210 and the lower mold 220 are molded together, the first surface 111 of the flexible light board 110 faces the first groove 211. When the fluid material enters the first cavity 300 from the glue inlet 213, the liquid level of the fluid material will submerge the first surface 111. Therefore, when the fluid material solidifies, the first encapsulating body 121 encapsulating the first surface 111 can be formed. Since the fluid material will not enter between the second surface 112 and the bottom wall of the third groove 221, the second surface 112 will not be encapsulated.

[0080] In step S40, the flexible light board 110 and the first encapsulating body 121 are placed as a whole in the fourth groove 222, with the first encapsulating body 121 facing downward and in contact with the bottom wall of the fourth groove 222. When the upper mold 210 and the lower mold 220 are closed, the second surface 112 of the flexible light board 110 faces the second groove 212. When the fluid material enters the second cavity 400 from the glue inlet 213, the liquid level of the fluid material will cover the second surface 112. Therefore, when the fluid material solidifies, the second encapsulating body 122 covering the second surface 112 can be formed. Since the fluid material will not enter between the first encapsulating body 121 and the bottom wall of the fourth groove 222, the first encapsulating body 121 will not be covered.

[0081] It can be understood that, since the flexible light board 110 has a thickness, the flexible light board 110 is formed with a side wall connecting the first surface 111 and the second surface 112. If the thickness of the flexible light board 110 is large, when the flexible light board 110 is placed in the third groove 221, the side wall of the flexible light board 110 can fit the peripheral wall of the third groove 221. Therefore, the fluid material entering the first cavity 300 will only cover the first surface 111, and will not flow into the gap between the side wall of the flexible light board 110 and the peripheral wall of the third groove 221. The finally formed first encapsulation body 121 will not cover the flexible light board 110. side wall; and when the integrated structure of the flexible light board 110 and the first encapsulating body 121 is placed in the fourth-type groove 222, there is a gap between the side wall of the flexible light board 110 and the peripheral wall of the fourth-type groove 222, so that the fluid material entering the second cavity 400 will flow into the gap between the side wall of the flexible light board 110 and the peripheral wall of the fourth-type groove 222, so that the finally formed second encapsulating body 122 will cover both the second surface 112 and the side wall of the flexible light board 110, so that the encapsulating structure 120 formed by connecting the first encapsulating body 121 and the second encapsulating body 122 can wrap the entire flexible light board 110.

[0082] In some embodiments, the first cavity 300 and the second cavity 400 are adapted to the appearance of the flexible light board 110. It can be understood that the first groove 211, the second groove 212, the third groove 221 and the fourth groove 222 are all adapted to the appearance of the flexible light board 110. Therefore, the third groove 221 and the fourth groove 222 can play a positioning role in the flexible light board 110 and the integrated structure of the flexible light board 110 and the first encapsulation body 121, so that the flexible light board 110 and the integrated structure of the flexible light board 110 and the first encapsulation body 121 are firmly positioned in the first cavity 300 and the second cavity 400, and the first groove 211 and the second groove 212 are also adapted to the appearance surface of the flexible light board 110, so that the manufactured first encapsulation body 121 and the second encapsulation body 122 can be adapted to the appearance surface of the flexible light board 110, thereby ensuring that the size of the manufactured encapsulation structure 120 is accurately controlled, avoiding material waste, saving costs, and also ensuring that the size and appearance of the encapsulation structure 120 have good consistency.

[0083] It can be understood that since the light-emitting element 113 and the power supply element 114 etc. will protrude from the first surface 111 or the second surface 112, the bottom walls of the third type groove 221 and the fourth type groove 222 can be provided with a recessed making way portion 223 to make way, thereby making the positioning effect of the third type groove 221 and the fourth type groove 222 better.

[0084] In some embodiments, the material preparation step S20 includes:

[0085] Prepare component A and component B, mix component A and component B according to a preset ratio to form liquid silicone, and perform vacuum treatment on the liquid silicone.

[0086] That is to say, the fluid material is liquid silicone. Liquid silicone is a transparent material. When the liquid silicone is heated, it can be vulcanized to become a solid structure. Liquid silicone has the advantages of good fluidity, fast vulcanization, safety and environmental protection, tear resistance, good resilience, and strong thermal stability. Liquid silicone also has good biocompatibility and non-toxic properties, and is suitable for the field of medical supplies. Since the coating structure 120 of the phototherapy device 100 is in direct contact with human skin, the coating structure 120 is made of liquid silicone, which can effectively reduce the harm to the human body. Of course, in other possible implementations, the fluid material can also be rubber, polyurethane glue or epoxy resin glue, etc. The embodiment of the present application does not make a sole limitation on the specific composition of the fluid material.

[0087] Specifically, component A and component B are mixed and stirred to make the mixture more uniform. Since bubbles will be generated when component A and component B are mixed and stirred, these bubbles will affect the smoothness and integrity of the final product, so vacuuming is required. Specifically, the mixed liquid silicone can be placed in a vacuum machine and vacuumed at a preset pressure.

[0088] By mixing component A and component B to form a two-component liquid silicone and performing a vacuum treatment, the silicone can be molded within a relatively low temperature range. The silicone can be covered on the surface of a heat-sensitive product under relatively low temperature conditions to prevent the coating structure 120 from damaging electronic components such as the power supply element 114 on the flexible light board 110 during the molding process.

[0089] Specifically, component A is the main body of silica gel, including organic liquid silica gel and a crosslinking agent, and component B includes a catalyst.
