AI Technical Summary
In existing technologies, thin phosphor films are prone to deformation and edge lifting when bonded to LED chips, resulting in incomplete bonding and affecting light conversion efficiency.
An LED multilayer fluorescent film manufacturing device is used. By using a main scraper and an auxiliary scraper, fluorescent adhesive and transparent adhesive are evenly laid on the base film. The film is then heated to semi-cur it, forming a double-layer fluorescent film. The addition of transparent adhesive increases the thickness and prevents the edges from curling.
The manufactured fluorescent film maintains a high light conversion efficiency while avoiding edge curling, ensuring good adhesion to the LED chip and improving light conversion efficiency.

[0017] The present invention will be further described in detail below with reference to specific embodiments.
[0018] like Figure 1 As shown, the fluorescent film manufacturing device has four support legs 9, and a base 90 is supported on the support legs 9. A laying platform 3 is provided on the base 90. Before manufacturing the fluorescent film, the operator first adjusts the four support legs 9 to adjust the laying platform 3 to a horizontal state. Correspondingly, the operator operates the horizontal adjustment mechanism on the main and auxiliary support frames 12 and 22, namely screws 13 and 23, to adjust the main and auxiliary scrapers 1 and 2 until their horizontal indicators 15 and 25 (in this embodiment, the horizontal indicator is a spirit level) show a horizontal state. Then, the base film is laid on the laying platform 3. Then, the negative pressure adsorption device is activated, and the base film is adsorbed onto the surface of the laying platform 3 by using the negative pressure adsorption holes 310 opened on the laying platform 3.
[0019] See Figure 1After the above preparation, the main glue injector 73 starts to inject fluorescent glue material to the back of the base film on the laying table 3. The main drive motor 74, as the glue injection driving mechanism, drives the main moving rod 72, together with the main glue injector 73 mounted on the main moving rod 72, to move left and right above the back of the laying table 3 along the main track 71, so that the fluorescent glue material is uniformly injected to the back of the base film laid on the laying table 3. See Figure 2 The main scraper 1 drive motor 14, as the main scraper 1 driving mechanism, drives the main scraper 1 screw rod 11 to rotate, so that the main support frame 12 sleeved on the main scraper 1 screw rod 11, together with the main scraper 1 mounted on the main support frame 12, moves forward along the main scraper 1 screw rod 11 in the longitudinal direction, so that the injected fluorescent glue material is scraped forward to be uniformly laid on the surface of the base film. Then, the heating unit 32 is started to heat the fluorescent glue material to semi-solidification. See Figure 1 The auxiliary glue injector 83 starts to inject transparent glue material to the back of the semi-solidified fluorescent glue material. The auxiliary drive motor 84, as the glue injection driving mechanism, drives the auxiliary moving rod 82, together with the auxiliary glue injector 83 mounted on the auxiliary moving rod 82, to move left and right, so that the transparent glue material is uniformly injected to the back of the semi-solidified fluorescent glue material. See Figure 2 The auxiliary scraper 2 is located behind the main scraper 1. The auxiliary scraper 2 drive motor 24, as the auxiliary scraper 2 driving mechanism, drives the auxiliary scraper 2 screw rod 21 to rotate, so that the auxiliary support frame 22, together with the auxiliary scraper 2 mounted on the auxiliary support frame 22, moves forward along the auxiliary scraper 1 screw rod 21, so that the transparent glue material is scraped forward to be uniformly laid on the semi-solidified fluorescent glue material. Finally, the base film, together with the fluorescent glue material and the transparent glue material, is put into an oven to be baked until the fluorescent glue material and the transparent glue material are completely solidified, that is, the double-layer fluorescent film is completed.
[0020] See Figure 1 and Figure 2 After the completion of the fluorescent film, the main scraper 1 and the auxiliary scraper 2 can be operated to move forward to above the cleaning box 5. The cleaning box 5 is lower than the main scraper 1 and the auxiliary scraper 2. The pushing motor 51 pushes the cleaning box 5 mounted on the support frame 52 to move upward until the main scraper 1 and the auxiliary scraper 2 are soaked in the medicine water in the cleaning box 5, so that the medicine water can clean the residual glue and fluorescent powder on the main scraper 1 and the auxiliary scraper 2.
[0021] The above description is only an embodiment of the present application, which does not limit the patent protection range. The person skilled in the art can make non-essential changes or substitutions on the basis of the present application, which still falls within the patent protection range.
