A GRINDING METHOD OF STRIP GLASS AND A VACUUM SUCTION PLATE USED IN THE SAME

Abstract

 A grinding method of a strip glass comprises: the strip glass to be ground is absorbed to a vacuum suction plate, then the strip glass is transferred to the glass edge chamfering apparatus by the vacuum suction plate. Grinding a side of the strip glass forms a predefined slant. Also, the strip glass is turned over and is absorbed to vacuum suction plate, then the strip glass is transferred to the glass edge chamfering apparatus and grinding the other side of strip glass forms a slant, which is the same as the predefined slant. This invention can grind a strip glass having a width of 10mm or great smaller. The present method prevents a waste of the strip glass.

Description

[Technical Field]

[0001] The present invention relates to a grinding method of strip glass and a vacuum suction plate used in the same, primarily used for grinding to form strip glass with single ridge and double slants having small width (generally smaller than 15mm) in glass edge chamfering apparatus.

[Background Art]

[0002] During the architecture and fitment, glass becomes more popular. Grinding glass edge is an important step in process of glass, but conventional glass edge chamfering apparatus cannot grid the glass having width smaller than 15mm to form strip glass with single ridge and double slants, since the conventional clamps cannot clamp the glass having width smaller than 15mm, so that a great number of glass material having width smaller than 15mm cannot be used and then be wasted to pollute our environment. In the meanwhile, it is highly difficult and dangerous as clamping the glass manually, so it is necessary to provide a glass edge chamfering apparatus to solve this technical problem.

[Content of invention]

[0003] The object of the present invention is to provide a grinding method of strip glass and a vacuum suction plate used in the same to overcome the problem in which the conventional technology cannot grind strip glass. The technical projects of the invention are as follows: a grinding method of a strip glass, in which firstly, the strip glass to be ground is absorbed to a vacuum suction plate; secondly, the strip glass is transferred to the glass edge chamfering apparatus by the vacuum suction plate and a side of the strip glass is grinded to form a predefined slant; finally, the strip glass is turned over and is absorbed to vacuum suction plate, and then the strip glass is transferred to the glass edge chamfering apparatus and the other side of strip glass is grinded to form a slant which is the same as the above said predefined slant.

[0004] A vacuum suction plate comprises base plate, on edge of one side of which is provided with a suction surface in which is provided with suction grooves for absorbing the strip glass; exhaust passages are disposed within the base plate, communicated on one end thereof with an exhaust port on one end of the base plate, and intercommunicated with the suction grooves through branch passages and groove branch passages: and the suction surface has thickness smaller than other sections of the base plate to form an obtuse angle concave section at the corner.

[0005] The suction surface is composed of a suction layer made of elastic material adhered onto the surface of the base plate.

[0006] The suction layer is made of rubber or plastic or other elastic materials.

[0007] The said base plate can be formed by means of two sections engaged and adhered with each other, and the said exhaust passages and branch passages are disposed between the engaged surfaces of the said two sections.

[0008] The said base plate is made of metal, glass, plastic or polymethyl methacrylate plastics.

[0009] The advantage of the invention lies in: by means of vacuum-pumping, let the strip glass tightly adsorb suction surface, and combine base plate with strip glass as a whole, then make use of base plate for carrying strip glass to process on glass edge chamfering apparatus, it could grind the strip glass in 10mm width, even less than 10mm width, thus effectively solve the issue that the present clamp could not clamp strip glass. Simple structure is easy to implement and convenient to use. By means of processing mentioned in the invention, many abandoned strip glass could be processed into useful finishing material, making full use of glass material and reducing the waste of resources.

[0010] The above and other advantages and characterizes of the invention will become more clear with reference to following detailed description accompany with figures.

[Best Mode]

[0012] Reference to figures 1 to 3, the vacuum suction plate of the present invention comprises a base plate 1. on edge of one side of which is provided with a suction surface 2 in which is provided with a suction groove 3. Exhaust passages 7 are disposed within the base plate 1, communicated on one end thereof with an exhaust port 5 on one end of the base plate 1, and intercommunicated with the suction grooves 3 through branch passages 6 and groove branch passages 4. The suction groove 3 has function of improving the area and force of suction and shape of random.

[0013] Reference to figures 2 and 3, the suction surface 2 has thickness smaller than other sections of the base plate 1 and form a slant which has maximal thickness at the joint to the base plate 1 forms an obtuse angle concave section (step).When processing the glass strip, the obtuse angle concave Section is employed as function of positive stop, that is, a side of the processed glass strip resists against the joint of the concave section to prevent moving during the process of glass strip.

[0014] As shown in figure 3, the suction surface 2 is composed of a suction layer 8 made of elastic material adhered onto the surface of the base plate 8. A groove 3 and groove branch passages 4 are provided on the suction layer 8. It is advantageous for absorbing the surface of glass onto the suction layer 8 as it is elastic. The suction layer 8 can be made of rubber, plastic or materials with similar performance.

[0015] Regarding the convenience of production, the said base plate 1 can be formed by means of two sections engaged and adhered with each other, so that the said exhaust passages 7 and branch passages 6 can be disposed between the engaged surfaces of the said two sections and easily processed.

[0016] The said base plate 1 can be made of metal, glass, plastic, polymethyl methacraylate plastics, toughened glass or other materials.

[0017] As implementing according to the present invention, a hose is connected between the exhaust port 5 and the air extracting port of vacuum pump. The glass strip to be processed is placed onto the suction surface 2 of the invention, and the vacuum pump is activated to extract air to form vacuum status so that the glass strip is absorbed onto the suction surface 2. Subsequently, the invention is placed onto the glass edge chamfering apparatus to grind external side of the glass strip to form a slant, and then the glass strip is turned over and grinded with the other side thereof so that the glass strip can be processed to obtain the shape of single ridge and double slants or the other similar shape.

[0018] The above described is only the preferred embodiments of the present invention, which is just illustration and not limitation to the invention. Those skilled in the art can understand that the invention may be modified and amended on many places without separating from the scope and spirit of the invention which are limited in the protective scope of this invention.
