Description

Technical Field

[0001] The utility model relates to the technical field of glass processing, in particular to a vacuum glass with a novel vacuum pumping structure. Background Art

[0002] Vacuum glass is a common environmentally friendly glass with good sound insulation and heat insulation effects. The vacuum glass processing method generally involves bonding two pieces of spaced glass together, leaving an exhaust hole for subsequent vacuuming, and then sealing the hole. It is generally processed in at least two steps.

[0003] In addition, the existing melt coating sealing method metallizes the edge of the glass to form a metallization layer, and then coats solder on the metallization layer and welds it at high temperature to seal and fix the metallization layers of the two glasses. Since this method needs to be applied by manual coating, the amount of solder is not convenient to control. Too much or too little solder will lead to insufficient stability after welding or partial welding leakage, which is time-consuming and troublesome. In addition, if the angle of the glass changes or the position moves during the processing, the solder is easy to shift in position due to the smoothness of the glass, resulting in uneven welding and vacuum leakage. Therefore, it is necessary to provide a vacuum glass with a new vacuum structure that is convenient to apply solder, stable and convenient to fix solder, and reduces the steps of vacuum glass processing. Utility Model Content

[0004] The utility model provides a vacuum glass with a novel vacuum pumping structure to solve the problems raised in the above background technology.

[0005] In order to solve the above problems, the technical solution adopted by the utility model is:

[0006] A vacuum glass with a novel vacuum structure comprises two pieces of glass of the same size and arranged at a relative interval, the surfaces of the opposite glasses are all provided with a metallized layer, a hot melt tape is provided between the metallized layers of the two glasses, the concave-convex pattern of the hot melt tape is a hot melt tape that can be deformed after being heated at a high temperature, and is completely bonded and sealed with the metallized layer, and the two glasses are sealed to form a vacuum sealed glass without a vacuum hole. The two pieces of glass can be two rectangular glasses of the same or different sizes, and the two pieces of glass are placed in an external vacuum furnace, and the glass and the hot melt tape are processed in the vacuum furnace by vacuum brazing. Vacuum brazing is a welding process in which a filler metal is heated to a temperature above the melting point but below the melting point of a base metal under a vacuum state, and a weld is formed by the wetting and flow of the filler metal to the base metal. Both vacuum furnaces and vacuum brazing are prior arts and will not be described in detail here. The hot melt tape has a strip-like structure, which is convenient for laying on the metallized layer. At the same time, the concave and convex patterns on the hot melt tape can increase the friction coefficient to prevent the sealing tape from shifting due to the discharge of internal air between the two glasses during vacuuming.

[0007] Preferably, the width of the hot melt tape is 3 mm to 15 mm, and the thickness is 0.2 mm to 2 mm. The width and thickness of the hot melt tape determine the amount of sealing solder, and the amount of solder required for different glass sealing can be precisely controlled by adjusting the width and thickness of the hot melt tape.

[0008] Preferably, the hot melt tape is fixed on the metallized layer by spot welding. The hot melt tape is fixed on the metallized layer in advance to facilitate subsequent assembly and prevent the hot melt tape from shifting during the processing.

[0009] Preferably, the outer surface of the hot melt tape is provided with concavo-convex patterns, which can be three-dimensional stripes or three-dimensional dot patterns, and the concavo-convex patterns of the hot melt tape form a number of fine gaps connected to the hollow space between the two glasses. The concavo-convex patterns on both sides of the hot melt tape are patterns of the same shape, and the three-dimensional dot patterns can increase friction. At the same time, when the hot melt tape is fixed at high temperature, the three-dimensional dot patterns form a multi-point fixed structure similar to spot welding, which has a good fixing effect. When the three-dimensional stripes and the glass are combined and vacuumed, the gas can be quickly exhausted through the channels between the cloth patterns, thereby increasing the vacuuming speed.

[0010] The hot melt tape is hot melt tin.

[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] The utility model puts two sheets of glass in a vacuum furnace, and while the hot melt tape is heated to seal the periphery of the two sheets of glass, due to the gaps between the concave and convex patterns arranged on the surface of the hot melt tape, vacuuming is achieved during heating and welding. When the glass sheets are vacuumed in the vacuum furnace, gas can pass through the gaps between the patterns to speed up the vacuuming speed, thereby achieving a one-step processing of vacuuming and sealing of vacuum glass without air extraction holes.

[0013] The hot melt tape is not limited to metal materials and can be selected according to needs. There is no need to coat solder, which reduces the processing difficulty. The hot melt tape can be pre-placed on the metallized layer, which greatly shortens the manufacturing steps and time. The amount of solder can be adjusted by adjusting the thickness and width of the hot melt tape to achieve precise solder amount control for different glass processing. When heating and sealing, the solder is not easy to move, making the welding more uniform and the sealing effect better. BRIEF DESCRIPTION OF THE DRAWINGS

The two pieces of glass 1 can be two rectangular glasses of the same or different sizes, and the two pieces of glass 1 are placed in an external vacuum furnace, and the glass 1 and the hot melt tape 3 are processed by vacuum brazing in the vacuum furnace. Vacuum brazing is a welding process in which a filler metal is heated to a temperature above the melting point but below the melting point of the base metal under a vacuum state, and a weld is formed by the wetting and flow of the filler metal to the base metal. Both vacuum furnaces and vacuum brazing are prior arts and will not be described here. The hot melt tape 3 is in a strip-like structure, which is convenient for laying on the metallized layer 2. At the same time, the concave-convex pattern on the hot melt tape 3 can increase the friction coefficient to prevent the sealing tape from shifting due to the discharge of internal air between the two glasses 1 during vacuuming.

[0018] The width of the hot melt tape 3 is 3 mm to 15 mm, and the thickness is 0.2 mm to 2 mm. The width and thickness of the hot melt tape 3 are the amount of sealing solder, and the amount of solder required for sealing different glasses 1 can be accurately controlled by adjusting the width and thickness of the hot melt tape 3.

[0019] The hot melt tape 3 is fixed on the metallized layer 2 by spot welding. The hot melt tape 3 is fixed on the metallized layer 2 in advance to facilitate subsequent assembly and prevent the hot melt tape 3 from shifting during the processing.

[0020] The outer surface of the hot melt tape 3 is provided with concavo-convex patterns, which can be three-dimensional stripes or three-dimensional dot patterns. The concavo-convex patterns of the hot melt tape 3 form a number of fine gaps connected with the hollow space between the two glasses 1. The concavo-convex patterns on both sides of the hot melt tape 3 are patterns of the same shape, and the three-dimensional dot patterns can increase the friction force. At the same time, when the hot melt tape 3 is fixed at high temperature, the three-dimensional dot patterns form a multi-point fixed structure similar to spot welding, and the fixing effect is good. When the three-dimensional stripes and the glass 1 are combined and vacuumed, the gas can be quickly exhausted through the channels between the cloth patterns, thereby increasing the vacuuming speed.

[0021] The hot melt tape 3 can be hot melt tin or other metal inorganic welding materials.

[0022] When the utility model is used, the required amount of solder is calculated according to the type and size of the glass 1, and then the hot melt tape 3 with the corresponding thickness and width is selected, and the hot melt tape 3 is fixed on the metallized layer 2 by spot welding to ensure that the solder surrounds the glass 1 to prevent leakage. The two pieces of glass 1 are combined and placed in a prepared vacuum device to vacuum the cavity between the two glasses 1. During the process, the gap between the concave and convex patterns can accelerate the extraction of air between the two glasses 1 and improve the vacuuming efficiency. After the vacuuming is completed, the position of the hot melt tape 3 is heated to weld and seal.

[0023] The utility model does not need to manually apply solder, the amount of solder can be accurately controlled, the solder will not move during welding, the welding effect is good, and the gaps between the concave and convex patterns during vacuuming can speed up the extraction of air in the vacuuming layer and speed up the vacuuming speed.
