TECHNICAL FIELD

[0001] The application relates to a packaging device and a packaging method for producing a diffusion plate and belongs to the technical field of diffusion plate production and processing. BACKGROUND

[0002] The light diffusion plate is produced by using the physical phenomena of refraction, reflection and scattering of light when the light encounters two media with different refractive indexes in the path, by adding inorganic or organic light diffusion agents in the PMMA, PC, PS, PP or other base materials or by artificially adjusting the light by arranging the array of micro-features on the surface of the base material, so that the light is refracted, reflected and scattered in different directions, thereby changing the path of the light and realizing the effect of optical diffusion.

For those skilled in the art, the specific meaning of the above terms in the present application can be understood through specific circumstances.​ Example 1:

[0040] The packaging device for diffusion plate production provided in this embodiment of the invention is used for the production and packaging of diffusion plates. It can prepare adaptable packaging materials with a certain strength according to the specifications of different diffusion plates. The packaging has strong adaptability and can effectively ensure the packaging's shock resistance, bending resistance and other capabilities. To achieve the above functions, the device here includes a first support 1, a mounting plate 2, a lifting device and a pressing device.

[0041] Among them, such as Figure 1 As shown, the mounting plate 2 is installed above the first bracket 1. The mounting plate 2 has a groove for placing the diffuser plate, and multiple nozzles 3 are installed in the groove of the mounting plate 2. Several foaming filler gas cylinders 4 (which are foaming agents, a substance produced by combining polyurethane foam technology with aerosol technology. The components are very specialized, requiring polyurethane prepolymer, catalyst, and foaming agent. Currently, polyurethane foaming fillers are widely used in the market, and will not be discussed further here) are installed on the first bracket 1. The several foaming filler gas cylinders 4 are connected to the corresponding multiple nozzles 3. The foaming filler gas cylinders 4 are controlled by related solenoid valves and are used to fill the groove of the mounting plate 2 with foaming filler according to the instructions of the control unit. For some other materials that require hydration to expand and solidify rapidly, as another preferred method, a corresponding spraying device can also be set on the first bracket 1 to spray water mist into the groove of the mounting plate 2. When foaming and filling diffuser plates of different specifications, pay attention to using a holding device to ensure the limiting and fixing of the position of the diffuser plate to prevent the expanding material from pushing the diffuser plate off the mounting plate 2. Refer to Figure 1 As shown, the pressing device includes a pressure plate 17 and an actuating unit for driving the pressure plate 17 to rise and fall.

[0042] To remove the filled diffuser plate from the groove of the mounting plate 2, a lifting device is also provided. Specifically, a hollow opening is preferably provided on the mounting plate 2 away from the nozzle 3. The lifting device includes a lifting drive device 6 and a lifting plate 5 located at the output end of the lifting drive device 6 (the lifting drive device 6 can be a cylinder; the power source related to the drive device and the actuation device is already relatively existing technology, and will not be described in detail here). The lifting drive device 6 is used to drive the lifting plate 5 to rise and fall at the hollow opening. The size and specifications of the lifting plate 5 and the hollow opening are matched. The lifting plate 5 is as follows: Figure 1The plurality of shown can be connected with the output end of the jacking drive device 6 through the linkage 7 at the same time, the foaming filler is bonded with each other after solidification, the jacking plate 5 before solidification is located at the bottom of the groove, therefore the foaming filler after solidification and the diffusion plate can be directly jacked out through the jacking action, for the flat diffusion plate, the foaming filler after solidification has a certain thickness to support the strength of the packaged diffusion plate, has good anti-fracture and anti-seismic effect, for other special-shaped member diffusion plates, the pressing device should also be matched with the surface shape, the foaming filler can fill and solidify the space with gap position, has good anti-falling, anti-impact, anti-seismic and anti-crushing effect, can be directly packaged after solidification, and the foaming filler can be selected as an environmentally friendly material, has good application and market prospect.

[0043] The packaging device for diffusion plate production provided by the embodiment of the application prevents the foaming filler from being bonded with the bottom of the mounting disc 2 during solidification, and the device further comprises a foam cotton supply device. Figure 1 As shown, the foam cotton supply device comprises a second support 8 and a foam cotton roll 9 rotatably arranged on the second support 8, the foam cotton roll 9 is used to supply thin-layer foam cotton for cushioning the bottom of the mounting disc 2, in order to ensure that the foaming filler after solidification is not bonded with the mounting disc 2 to affect the removal of the foaming filler, the nozzle 3 is designed in a needle-sharp shape as a whole, the foam cotton roll 9 is used to lay a side of foam cotton material before the diffusion plate is placed in the groove of the mounting disc 2, and the pressing device is further used to press the foam cotton and be pierced by the plurality of nozzles 3, it should be noted that the process ensures that the nozzles 3 corresponding to the area all pierce the foam cotton, so as to avoid affecting the normal action surface of the foaming filler when the foaming filler is sprayed after the diffusion plate is placed. Through the above-mentioned mode, the foaming filler can push the foam cotton to the bottom layer of the mounting disc 2 after filling, which is beneficial to the jacking device to directly jack it out. As for the part of the lower surface of the diffusion plate in contact with the foaming filler, the foaming filler can be isolated through the film, and the film can be directly torn off during use.

[0044] The packaging device for diffusion plate production provided by the embodiment of the application, as Figure 3As shown, when the above-mentioned foam cotton application scheme is applied, since the pressing device needs to realize multiple functions, an optimized design is proposed here, specifically, the pressing device is provided with a plurality of pressing cylinders 18 installed on the bottom of the pressing plate 17, the number of the pressing cylinders 18 is the same as that of the nozzles 3, and each pressing cylinder 18 corresponds to the position of one nozzle 3, the pressing cylinder 18 is in a cylindrical shape and its inner diameter is greater than the outer diameter of the corresponding nozzle 3. When the foam cotton needs to be pierced, the pressing cylinder 18 acts on the surface of the foam cotton and is pressed downward along the piercing direction of the nozzle 3, and through the interaction of the array layout, it can be ensured that each pressing point is not affected by the deformation of the foam cotton, so as to ensure that the foam cotton can be pierced by the nozzle 3 and move downward by a certain amplitude. When the pressing device needs to press the diffusion plate, the corresponding nozzle 3 directly abuts against the upper surface of the diffusion plate, and it should be noted that the bottom of the nozzle 3 should have a certain size of contact surface to prevent local stress concentration and cause the diffusion plate to be damaged or the foam filler to be too strong to cause the diffusion plate to be broken. In order to prevent the installation precision of the individual pressing cylinder 18 or the precision of the action amplitude of the mechanism from causing uneven force of the individual pressing cylinder 18 on the diffusion plate, each pressing cylinder 18 is installed on the pressing plate 17 through an elastic element 19, so as to ensure that each pressing cylinder 18 can have a certain contact surface to make good contact with the diffusion plate and at the same time prevent the diffusion plate from being damaged.
