[0034] S4, pressing, the pressing assembly heat-presses the first film 210, the light strip body 100 and the second film 220, so that the first film 210 and the second film 220 fit and wrap the light strip body 100;

[0035] S5, output light strip.

[0036] In S3, the first film 210, the light strip body 100 and the second film 220 are arranged in sequence from top to bottom in the vertical direction to ensure that the light strip body 100 is located between the first film 210 and the second film 220 to ensure that the first film 210 and the second film 220 can wrap the light strip body 100 during pressing, and avoid the light strip body 100 from being misaligned relative to the first film 210 and the second film 220. In S4, the pressing assembly heat-presses the first film 210, the light strip body 100 and the second film 220 to make the first film 210 and the second film 220 fit and wrap the light strip body 100; the pressing assembly heat-presses so that the surfaces of the first film 210 and the second film 220 can be bonded to each other at high temperature and can be bonded to the light strip body 100. Under the pressure of the pressing assembly, the first diaphragm 210 and the second diaphragm 220 are tightly bonded to form a closed space that wraps the light strip body 100, and the first diaphragm 210 is in contact with the light-emitting side of the light strip body 100, and the second diaphragm 220 is in contact with the bottom side of the light strip body 100, forming a good waterproof barrier to ensure the safe use of the light strip body 100. This manufacturing method is simple and easy to operate. In addition, the first diaphragm 210 is provided with a light-transmitting structure to ensure that the light emitted by the light strip body 100 can pass through the first diaphragm 210, thereby ensuring its normal lighting function.

[0037] In this embodiment, refer to Figure 2 The pressing assembly includes: a first roller 310 and a second roller 320, wherein the first roller 310 and the second roller 320 are located on the same vertical line and are assembled up and down. When feeding, the first diaphragm 210, the second diaphragm 220 and the light strip body 100 are all fed toward the abutment between the first roller 310 and the second roller 320, and the first roller 310 and the second roller 320 rotate to make the first diaphragm 210, the second diaphragm 220 and the light strip body 100 fit tightly. In this embodiment, specifically, the first roller 310 is located on one side of the top surface of the first membrane 210, and the second roller 320 is located on one side of the bottom surface of the second membrane 220. In S4, when the first membrane 210, the second membrane 220 and the light strip body 100 are hot-pressed together, the first roller 310 rotates counterclockwise along the axis, and the second roller 320 rotates clockwise along the axis. The first roller 310 and the second roller 320 rotate in coordination to press the first membrane 210 and the second membrane 220 toward the light strip body 100 respectively.

[0038] Further, the pressing assembly is provided with one or more groups. In the present embodiment, the pressing assembly is provided with one group. In other embodiments, the pressing assembly may also be provided with several groups. According to the bonding strength requirements of the first diaphragm 210 and the second diaphragm 220, several groups of one-to-one corresponding first rollers 310 and second rollers 320 are provided so as to make the pressing of the first diaphragm 210 and the second diaphragm 220 and the light strip body 100 more closely fit. Specifically, refer to Figure 3 , the pressing assembly can be provided with two groups. In some embodiments, the pressing assembly can also be provided with three groups, four groups, etc.

[0039] In addition, in some embodiments, reference Figure 4 The pressing assembly may further include: a fixed operating device 410 and a third roller 420. The fixed operating device 410 is fixedly arranged on one side of the bottom surface of the second diaphragm 220, and the third roller 420 is arranged on one side of the top surface of the first diaphragm 210; the side of the fixed operating device 410 facing the third roller 420 is set as a fixed operating surface 411, which serves as a supporting surface, and the third roller 420 abuts against the fixed operating surface 411 of the fixed operating device 410. In S4, the third roller 420 rotates along the axis and cooperates with the fixed operating device 410 to press the first diaphragm 210 and the light strip body 100 toward the second diaphragm 220, so as to wrap the light strip body 100 between the first diaphragm 210 and the second diaphragm 220. The third roller 420 is provided with one, and the fixed operating device 410 is also provided with one, and the fixed operating device 410 is set as a fixed operating table. In other embodiments, according to the bonding strength requirement of the first diaphragm 210 and the second diaphragm 220, a plurality of third rollers 420 may be provided, and a plurality of fixed operating devices 410 may be provided correspondingly, one to one corresponding to the third rollers 420; Figure 5 The fixed operating device 410 may also be provided with a device whose length is greater than the sum of the diameters of the plurality of third rollers 420 and is pressed together with the plurality of third rollers 420 .

[0040] In this embodiment, the first diaphragm 210 and the second diaphragm 220 are both flexible diaphragms to ensure the flexibility of the manufactured light strip, increase its convenience of use and broaden its scope of application, and avoid the poor flexibility caused by the curing of the colloid in the conventional light strip and the hardness problem of the sleeve itself. In this embodiment, the material of the first diaphragm 210 and the second diaphragm 220 is TPU, which has excellent characteristics such as high tension, high tensile force, strong toughness, aging resistance and high waterproof and moisture permeability. The use of TPU ensures the high flexibility of the first diaphragm 210 and the second diaphragm 220. In addition, in this embodiment, the thickness of the first diaphragm 210 with a light-transmitting structure is 0.1 mm, which ensures that the thickness of the light-transmitting film surface is thin enough to ensure that it has strong light transmittance, further ensure that the light color and light effect emitted by the light strip body 100 are not affected, avoid the problem of color deviation and light effect reduction, and ensure the high light efficiency characteristics of the entire light strip. In this embodiment, the first diaphragm 210 is provided with a transparent structure so that the light emitted by the light strip body 100 can pass through. In this embodiment, the thickness of the second diaphragm 220 can be adjusted according to actual needs, and no specific limitation is made here. In some embodiments, the thickness of the first diaphragm 210 is 0.2 mm or 0.3 mm. In some embodiments, the material of the first diaphragm 210 and the second diaphragm 220 can also be silicone, PE glue, ABS glue, etc.

[0041] In this embodiment, refer to Figure 1, before S3, the following steps are also included: S2, preheating. Specifically, before feeding, the first roller 310 and the second roller 320 are preheated to ensure that the contact surfaces of the first and second diaphragms 210 and 220 can maintain high temperatures, so as to ensure that the surfaces of the first and second diaphragms 210 and 220 can be bonded, so that the two can be bonded under the pressure of the first and second rollers 310 and 320. Among them, the preheating temperature is set to 150℃-160℃. In this embodiment, the preheating temperature is set to 160℃. In other embodiments, the preheating temperature can also be set to 150℃, 151℃, 152℃, 153℃, 154℃, 155℃, 156℃, 157℃, 158℃, and 159℃. It is sufficient that the preheating temperature range is 150℃-160℃, and no specific limitation is made here. When the first roller 310 and the second roller 320 are preheated to a temperature at which the surfaces of the first film 210 and the second film 220 can be bonded, a temperature control device is used to keep the first roller 310 and the second roller 320 at a constant temperature to ensure that during the lamination process, the first film 210 and the second film 220 can be bonded to each other or to the light strip body 100. When the pressing assembly is provided with multiple groups, that is, multiple groups of rollers are provided, the rollers close to the feed side can be preheated in advance, and the rollers away from the feed side can be heated later. The rollers close to the feed side are preheated to the set temperature and maintained at a constant temperature, and then the material can be fed for pressing, and the rollers away from the feed side continue to be heated to the set temperature and maintained at a constant temperature after being heated to the set temperature. This can save time without waiting for all rollers to be preheated to the set temperature before starting feeding, and can also ensure that the surfaces of the first diaphragm 210 and the second diaphragm 220 can be bonded during pressing, so as to facilitate mutual bonding or respectively bonding to the light strip body 100.

[0042] It should be noted that the thickness selection of the first diaphragm 210 and the preheating temperature setting of the first roller 310 are determined according to the material of the first diaphragm 210 and are adaptively modified, and the preheating temperature setting of the second roller 320 is determined according to the material of the second diaphragm 220 and is adaptively modified.
