Abstract
The present invention discloses an integrated, non-blind zone automobile rear-view mirror welding method, characterized by: stacking together the primary visual area mirror and the vision blind zone mirror along the adjoining plane, heating the primary visual area mirror and the vision blind zone mirror, and applying appropriate pressure; welding and integrating the adjoining plane when the temperature reaches the welding state. The direct thermal welding is heating and pressurization without adding any medium to weld the adjoining plane to integrate the two parts. The indirect heat welding is adding beading medium at the adjoining plane, heating to the welding temperature of the medium, and integrating the primary visual area mirror and the vision blind zone mirror by the medium. The invention has beneficial effects of realizing the scale production of integrated non blind zone automobile rear-view mirror products, commendably welding together the primary visual area mirror and the vision blind zone mirror with two identical glass materials or different glass materials, to form integrated products. In this way, two components of the primary visual area mirror and the vision blind zone mirror can be processed separately, thereby reducing the processing difficulty.
Description
Technical field
The present invention and a kind of automobile rear view mirror without dead zone relate in particular to a kind of welding process of integrated welding automobile rear view mirror without dead zone.
Background technology
At present, traditional automobile outer rear-view mirror mainly is plane mirror or spherical reflector, and it is little all to exist vision area, the shortcoming that the blind area is big.There is data to show, many traffic accidents, special traffic accident when automobile turning, because the existence of backsight blind area is arranged, the officer can't observe that the car back car causes.Therefore how to eliminate the emphasis that the backsight blind area becomes the automobile rearview mirror design.The non-blind area mirror of mentioning in the patent of in the past announcing is to add ablepsia district mirror on the basis of primary vision area mirror, and its structure is divided into inserted, SMD and integrate shaped type.Wherein inserted and SMDly there is potential safety hazard, and the processing and assembling complexity.The processing method of the automobile rear view mirror without dead zone of existing integrate shaped type is, is the blank of desired shape and size with the compression molding of glass material one earlier, then blank is carried out optical surface polishing processing, plates reflectance coating again.The one mold pressing is very high to the requirement of mould pressing process, and follow-up optical surface is processed, the difficulty of plated film is very big, and manufacturing cost is very high.Such method can't be produced in enormous quantities, and when the material of primary vision area mirror and ablepsia district mirror is different, just can't adopt this method.
Summary of the invention
The objective of the invention is to overcome the difficulty of existing integral forming method processing, provide a kind of difficulty of processing little, can be the integrated welding automobile rear view mirror without dead zone welding process of the primary vision area mirror of same glass material or different glass material and ablepsia district mirror welding formation one.
The technical solution adopted for the present invention to solve the technical problems is: the primary vision area mirror of welding and ablepsia district mirror are stacked, put into process furnace and heat primary vision area mirror and ablepsia district mirror simultaneously, heat when glass is in as-welded, make the mutual welding in junction surface form one.
This patent also proposes, and adds more low-melting beading medium between the junction surface of primary vision area mirror and ablepsia district mirror, makes welding to carry out under lesser temps (200 ℃～600 ℃), reduces the difficulty and the cost of fusion process.
The invention has the beneficial effects as follows, the scale production of integrated automobile rear view mirror without dead zone product is achieved, the primary vision area mirror of two kinds of same glass materials or different glass material and ablepsia district mirror can be welded together well, form incorporate product.In this way, but primary vision area mirror and two parts separate machined of ablepsia district mirror have reduced difficulty of processing.

Label declaration: 1 primary vision area mirror, 2 ablepsia district mirrors, 3 welding medium layers.
Embodiment
The invention will be further described below in conjunction with accompanying drawing.
The first string as shown in Figure 1, be the direct heat burning-on method: do not add any beading medium between primary vision area mirror and the ablepsia district mirror, primary vision area mirror and ablepsia district mirror that optical polish is good are stacked along the junction surface, in order to reach better welding effect, apply suitable pressure (0kgf～10kgf) at the end face of ablepsia district mirror, heat primary vision area mirror 1 and ablepsia district mirror 2 simultaneously, heat when glass is in as-welded (400 ℃～800 ℃), keep constant temperature for some time to welding mutually, cooling then, when dropping to room temperature, can mutual welding become one.In technological process of the present invention, the force value arbitrarily in this pressure interval range and temperature range scope all can be mated use mutually with temperature value arbitrarily, reaches purpose of the present invention.
Second scheme as shown in Figure 2, be that the employing glass powder with low melting point is the indirect hot melting connection of welding medium, concrete grammar is as follows: get an amount of low melting point transparent glass powder earlier, add water furnishing scattered paste shape (ratio 1: 3～1: 10), evenly spread upon on the junction surface in primary vision area mirror and ablepsia district, both are stacked then, be positioned in the process furnace and heat, in order to reach better welding effect, apply suitable pressure (0kgf～10kgf) in the lower surface of the upper surface of ablepsia district mirror or primary vision area mirror or other place, the fusing point of this dielectric material is low than the fusing point of the glass material of primary vision area mirror and ablepsia district mirror, makes welding to carry out under lower Heating temperature; When temperature reaches (200 ℃～600 ℃) when making the transparent glass powder be in as-welded, constant temperature for some time makes the junction surface be in as-welded, and welding medium layer 3 mutually combines with primary vision area mirror 1 and ablepsia district mirror 2, when dropping to room temperature, can mutual welding become one.In this technological process, force value arbitrarily in this pressure interval range and temperature range scope all can be mated mutually with temperature value arbitrarily and be mated use mutually with the arbitrary proportion value in 1: 3～1: 10 the proportional range of transparent glass powder and water, reaches purpose of the present invention.
The 3rd scheme as shown in Figure 3, be that to adopt the low melting glass thin slice be the indirect hot melting method of welding medium: low melting glass thin slice or the thin slice (0.05mm～2mm) place between the junction surface in primary vision area mirror and ablepsia district that makes with low-melting transparent glass powder, three are stacked, be positioned in the process furnace and heat, apply suitable pressure (0kgf～10kgf) in the lower surface of the end face in ablepsia district or primary vision area mirror or other place, when temperature reaches when making thin slice be in as-welded (200C～600 ℃), constant temperature for some time, the welding medium layer 3 (glass flake) that is in the junction surface mutually combines with primary vision area mirror 1 and ablepsia district mirror 2, when dropping to room temperature, can mutual welding become one.In this technological process, force value arbitrarily in this pressure interval range and temperature range scope all can be mated mutually with temperature value arbitrarily and be mated use mutually with any thickness value of transparent glass in 0.05mm～2mm thickness range, reaches purpose of the present invention.
These three kinds of schemes can both guarantee enough heat seal strengths, satisfy service requirements, and primary vision area mirror 1 can be that identical material also can be a unlike material with ablepsia district mirror 2.
