Description
Technical Field
The utility model relates to the technical field of polishing equipment, in particular to equipment for polishing the surface of curved glass.
Background
The vehicle-mounted display panel comprises a central control display panel, an instrument display panel, a head-up display screen, an electronic rearview mirror display screen, a rear seat entertainment display screen and the like.
In recent years, the market of vehicle-mounted panels has developed in a large-screen development trend (as shown in fig. 5, a central control display panel, an instrument display panel and the like are integrated), so that an adaptive 3D glass panel (or called 3D large-curved glass or curved glass piece) is formed, and the 3D glass panel has the characteristics of light weight, thinness, fingerprint resistance, glare resistance, hanging damage resistance and the like, can realize the bending and folding of the surface of the vehicle-mounted display screen, can still realize a high-quality display effect after the edge bending, thereby realizing the seamless connection of the three-dimensional surface in an uneven instrument panel area, improving the degree of freedom of design and function integration, further providing man-machine interaction interface functions and entertainment carriers, and has become the main trend of future development of the vehicle-mounted panel.
The current 3D large curved glass is formed by processing the mold molding; in the molding process, when the mold is cleaned, the quality of the produced 3D large-curved glass is better (no tiny pits) in the first several batches; after a period of production, there is a small amount of material adhering to the mold due to the stripping, resulting in a decrease in production quality (insufficient surface smoothness). At present, a plurality of companies in the market directly use products formed by the mold on an automobile without subsequent treatment; although the basic requirements are met, it is somewhat rough for some high standard-requiring automobiles. Of course, some companies will polish the product before it is installed on the car.
However, at present, polishing and grinding processing for the vehicle-mounted display panel is very simple and is performed in a metal polishing manner, for example, coarse wax, a grinder, a yellow coarse sponge disc and the like are adopted, and polishing is performed manually or by means of a very simple mechanical structure. The polishing mode has low polishing efficiency on one hand and uncontrollable quality on the other hand, and the qualification rate is not particularly ideal.
Therefore, the company develops polishing equipment (abandons the current crude processing mode) for automatic production aiming at vehicle-mounted 3D large-curved-surface glass so as to improve the production efficiency and control the polishing quality.
Disclosure of utility model
The utility model aims to overcome the defects of the prior art, provides equipment for polishing the surface of curved glass, and solves the problems of poor polishing effect, low polishing efficiency, low polishing qualification rate and easiness in damaging the curved glass.
It should be noted that, the current vehicle-mounted display panel gradually adopts integrated 3D curved glass (for example, a hollow display panel and an instrument display panel are integrated), but the current market does not have industrial equipment for polishing curved glass, but only uses some simple mechanisms manufactured in a metal polishing manner, so that the requirements of mass industrialization, high efficiency and stable and controllable quality cannot be met.
For example, in the simple mechanism prepared by the existing metal polishing method, a fixed workpiece is ground and polished by a rotating member; the polishing may be performed with a chemically aggressive polishing solution or with a polishing slurry. However, the polishing solution and the polishing material can flow away quickly, and can be reused after being manually collected and filtered. Not only the polishing efficiency is low, but also the waste degree of polishing liquid and polishing material is high; the polishing solution and the polishing material are expensive, and the cost is increased in an intangible way. Therefore, the curved glass piece on the automobile is not polished and polished as much as possible in view of cost and efficiency.

(Seventh) on the basis of the first aspect, one or more of the first to fourth advantageous configurations can be arbitrarily selected; in addition, in each advantageous embodiment, one or more of the respective alternatives, or else, can also be selected at will. I.e. between the schemes, can be selected and then combined to form a new scheme. The combination of permutations is not described in detail herein.
To facilitate understanding, some core design points of the solution are described:
1. Can automatically polish, and the working efficiency is improved
In the polishing field, the adopted polishing mode mainly refers to a metal polishing method; two common metal polishing modes: one is to fix a single workpiece, grind and polish the workpiece by a rotating mechanical part (or the mechanical part is fixed and the workpiece rotates), and add polishing solution or abrasive with chemical corrosion during polishing; in another polishing mode, the small parts are mixed with the abrasive and stirred together, and then the polishing liquid is added. The former polishing mode has very strict requirements on the clearance between a workpiece and a mechanical part during polishing (the polishing result is quite different even if the clearance deviation is 1-2mm, the clearance is mainly influenced by the polishing effect), so that the workpiece is very slow to install and cannot be automatically placed and polished, and the efficiency is very low; the latter polishing mode is only suitable for deburring and polishing small-sized pieces, and cannot polish curved glass pieces.
In this scheme, through adsorbing I a plurality of curved surface glass pieces of disposable circumference hoist and mount of frock, polish through arranging polishing mechanism IV in the I center department of absorption frock. The polishing device can polish a plurality of workpieces at one time without seriously affecting the polishing effect, and is mainly because: ① The grabbing mechanical mechanism II and the adsorption tool I are arranged in a structure, so that when the grabbing mechanical mechanism II grabs the adsorption tool I to be placed in the polishing barrel III, the position of the adsorption tool I in the polishing barrel III is very accurate, and position deviation is not easy to occur; ② The polishing mechanism IV is arranged on the flexible lifting mechanism, the polishing mechanism IV slightly shakes during polishing, a gap between the polishing mechanism IV and a workpiece can be changed (the gap affects the polishing effect, and the main reason is that the gap affects the pressure of a mechanical part on the workpiece, so that friction force is affected, and polishing is further affected).
In a popular way, the scheme weakens the influence of the gap on the polishing effect in unit time by intermittently contacting the workpiece and the polishing mechanism IV. Although the grinding effect of the scheme is not good in a traditional mode in unit time, the scheme is not strict in clearance requirements, namely, the clearance requirements between the curved glass piece and the polishing mechanism IV are not strict, automatic installation and one-time installation of a plurality of workpieces (clearance errors are avoided during installation), production efficiency is greatly improved for mass production enterprises, and the scheme is suitable for industrial production.
2. The polishing process is more controllable, and the polishing effect is improved
In the polishing finishing field, the grinding and polishing process is very difficult to control, and as long as one factor fluctuates, the polishing effects are different, sometimes even the same equipment, the same worker, the same batch of workpieces and the same batch of polishing materials are different, and the polishing effects are different and have a small rejection rate; the reason for this is that the polishing effect is affected by too many factors, which are too uncontrollable (for example, when polishing materials are added, the amount of materials which remain in the processing gap after each addition cannot be guaranteed to be uniform, when chemical polishing liquid is added, the amount of materials which remain in the processing gap after each addition cannot be guaranteed to be uniform, and even slight fluctuation of the amount of materials affects the polishing effect).
If the polishing can be automated, the working efficiency is improved, and the conventional polishing mode mentioned in the paragraph has the following defects: when polishing, only the amount of polishing material and polishing liquid is reduced, quantitative material is added manually or intermittently mechanically, but the specific reduction is difficult to explain, and only experience is adopted; and the addition times are too large, so that the fluctuation of the material quantity at the gap is too large and the polishing is not facilitated.
In the scheme, as mentioned in the paragraph of 'one, can automatic polishing, the work efficiency is improved', the polishing mechanism IV is intermittently contacted with the workpiece to weaken the influence of the gap on polishing, so that the polishing process is better controlled.
In the scheme, more polishing materials are concentrated at the position to be polished by controlling the opening and closing of the corresponding electromagnetic units, so that the polishing effect is improved; namely, the polishing material is controlled, so that the polishing process is better controlled.
In the scheme, the polishing material has physical material and chemical material, and the electromagnetic unit guides the polishing material, so that the contact between the chemical material and a workpiece is indirectly guided; compared with the traditional polishing mode, the scheme has the advantages that chemical materials are more controllable, so that the polishing process is better controlled.
In the scheme, the polishing mechanism IV and the curved glass piece are immersed in polishing liquid of the polishing barrel III, polishing materials are arranged in the polishing liquid, the rotation directions of adjacent polishing balls in the polishing mechanism IV are opposite (clockwise/anticlockwise), an ultrasonic vibrator is further arranged, and the polishing mechanism IV can slightly shake to change a gap between the polishing mechanism IV and a workpiece. When in operation, the device comprises: ① The polishing material is guided to a certain key polishing position of the curved glass piece through the electromagnetic unit, polishing is carried out in a chemical corrosion mode, and when the polishing mechanism is close to a workpiece, the polishing mechanism IV generates pressure and friction force to the workpiece through the polishing material, so that physical polishing is realized; ② When the polishing mechanism IV is close to the workpiece and in the polishing process, some polishing materials and the residual materials after the workpiece is ground are thrown away, the thrown away polishing materials and residual materials roll in the polishing barrel III, but the polishing materials can be reused under the magnetic effect, and the residual materials sink; when the polishing mechanism IV is far away from the workpiece, the thrown polishing material can be reused, and the rest material at the gap is shaken off under the action of the ultrasonic vibrator.
As can be seen from the description in the previous section, in the scheme, the polishing material at the grinding gap is dynamically changed and can be thrown off and reused, and the rest material can be thrown off and settled; the method has the advantages that the influence of the residual materials on the workpiece at the grinding gap is avoided, and the polishing and grinding process is facilitated to be controlled. It can be seen from the description in the previous paragraph that the polishing material in the present embodiment is recycled in the polishing barrel iii, so that the polishing degree effect of each stage, for example, the polishing degree in the first 10min, the polishing degree in 10-20min, and the polishing degree in 20-30min, is convenient to properly design the whole polishing stage (the conventional polishing method is unfavorable for grasping the polishing process because the polishing material is continuously added, and the ratio of the new abrasive to the old abrasive at the gap after the new abrasive is added is not manually and accurately controlled).
3. The cost is reduced
If the polishing process is more controllable, the polishing effect is improved, the conventional polishing mode is to continuously add polishing materials and chemical polishing liquid, and the cost of the polishing materials and the chemical polishing liquid is very high, so that the mode without cost is unfavorable for industrial processing and production. Although the polishing solution can be recycled and filtered for reuse, the polishing solution can be precipitated and then reused, the quality of the recycled material is uncontrollable each time, and the time period for subsequent use cannot be determined; many times, it is not possible to continue the use even when it is used as a low-grade product.
In this scheme, polishing material, polishing solution itself just in polishing barrel III, in polishing process circulation use all the time, only need according to the polishing effect of different time periods design whole polishing process can. The polishing materials and the polishing liquid in each batch are fully utilized, the cost is obviously reduced, and the method is suitable for industrial production.
The utility model has the following advantages: (1) The automatic processing can be realized, a plurality of workpieces can be processed at one time, the polishing efficiency is obviously improved, and the polishing machine is suitable for industrial production; (2) The polishing process and polishing factors are controlled more accurately, so that the polishing effect can be remarkably improved by reasonable adjustment; and (3) the production cost is reduced, and the method is suitable for industrial production.
