Description

TECHNICAL FIELD

[0001] The present application belongs to the field of glass processing, and relates to a glass door processing technology with a double-glass one-cavity and a light-emitting LOGO. BACKGROUND

[0002] At present, there are two conventional types of hollow glass according to the cavity for display cabinet glass doors: two-glass one-cavity and three-glass two-cavity, and a few three-glass one-cavity are used. The light-emitting effect of the LOGO in the inner cavity of the hollow glass of the display cabinet on the market is achieved by the following conventional structural devices:

[0003] 1. Two-glass one-cavity hollow glass: (1) One is to install a LOGO light-emitting lamp panel or a light-emitting device with a three-dimensional LOGO in the cavity of the hollow glass, which generally adopts a traditional wire connection mode. However, due to the transparent nature of the glass, the metal pipe or the whole injection pipe used for connecting the wire with the LOGO is present in the hollow cavity, and this phenomenon can be clearly seen by the naked eye, which cannot be avoided. Even if the LOGO is designed to be more attractive, there are still two metal pipes or one injection pipe supporting the LOGO above the LOGO and connected to the perforated partition strip, which directly affects the aesthetic appearance of the whole glass door body from the perspective of design professionals or consumers.

[0004] (2) One is to silk-screen light-emitting ink on the back glass (super white tempered glass) to make the LOGO have a light-emitting effect. Although the two-glass one-cavity structure achieves the ideal light-emitting effect, the super white glass only achieves the light-emitting effect of the LOGO. The heat transfer coefficient (i.e. U value) of the super white glass used in the configuration of the hollow glass does not meet the requirements of the configuration of the hollow glass, and the thermal insulation performance is affected, which is still unacceptable to customers.

[0005] 2. Three-glass two-cavity hollow glass: When processing the product with a silk-screen LOGO with a light-emitting effect, a three-glass two-cavity structure is usually used to achieve it. Since the three-glass two-cavity hollow glass is 7.5 kg heavier than the two-glass one-cavity per square, it leads to the increase of the weight of the whole door body, the bending deformation of the door frame profile, the sagging of the door body, and other adverse effects. Especially when making a hollow glass door body with a larger size, a lining iron needs to be inserted into the inner cavity of the PVC profile for reinforcement. After the lining iron is inserted into the inner cavity of the PVC profile, the weight of the glass door is increased, the process is complicated, the labor intensity is increased, and the final effect is not very ideal.

[0006] 3, three glass cavity hollow glass: in order to overcome the three glass two cavity with silk screen LOGO hollow glass bring the prior art of the deficiency, subsequently provided a kind of not only can effectively improve the glass appears condensation bad phenomenon, and can reduce the weight of the entire display cabinet door, simultaneously make glass silk screen LOGO with luminous effect is recognized by customer, the cost relative advantage of three glass cavity structure of hollow glass. With this three glass cavity structure (hollow cavity top suspension a piece of super white glass with silk screen luminous LOGO) processing, in process operation complex, low degree of automation, this also causes production limitation. Such production mode, not only increases the labor cost, also affects production efficiency, and the overall yield is difficult to have substantial improvement. SUMMARY

The process for manufacturing a double glass cavity door with a light-emitting logo according to claim 1, characterized in that: The specific steps of the step 4) of the front piece glass manufacturing are as follows: first, purchase the required glass, input the size and shape of the product into the numerical control cutting machine computer for optimized cutting of the glass, then place the cut glass on the machining center to process the C-shaped edge safety angle of the glass, ensure that the length and width size precision of the glass is controlled within ±0.2mm, clean the glass, and then perform appearance effect silk screen printing on the qualified glass, and detect the coated surface with a tin surface detector, place the glass with the coated surface upward on the workbench for printing, install the 300-mesh silk screen on the silk screen printing machine, adjust the size of the glass to be printed, print according to the requirements of the drawing, then move the printed semi-finished glass into a 170℃ tunnel furnace for 15-20 minutes of preheating and baking, and check whether the semi-finished silk screen printed glass has dew point and burr defects.

7. The process for manufacturing a double glass cavity door with a light-emitting logo according to claim 1, characterized in that: The specific steps of hollowing the piece in step 5) are as follows: firstly, the back piece glass with qualified silk screen printing is cleaned, after cleaning, the insulating spacer coated with butyl glue is placed on the super white glass with silk screen printing LOGO of the back piece, then the front piece glass with qualified silk screen printing is cleaned by the cleaning machine, the front piece glass with silk screen printing is combined with the back piece super white glass, the hollow glass cavity is clean and free of dirt, the hollow thickness error is controlled within ±0.5mm, and the glue is punched for secondary sealing, so as to produce the hollow glass with two glasses and one cavity.

8. The double glass one cavity glass door processing technology with a light-emitting LOGO according to claim 1, characterized in that: The step 6) is profile and aluminum alloy processing: firstly, the upper profile and the left and right PVC profiles are cut, drilled and drilled and milled according to requirements; similarly, the lower profile is sleeved with the lower aluminum alloy, and then cut and drilled.

9. The double glass single cavity glass door processing technology with a light-emitting LOGO according to claim 1, characterized in that: The step 8) is door body assembly: the whole door frame assembly is placed on the workbench to automatically glue the door frame in a whole circle, then the hollow glass is placed from top to bottom in the corresponding position of the door frame, the bent aluminum alloy U-shaped outer frame is fixed on both sides from the corresponding position of the two end profiles of the upper part of the door frame, and the handle is clamped on the hole of the left PVC profile and then solidified; After solidification, each accessory is installed, the door body is cleaned, packaged and stored.
