る。However, in the above-described conventional method for chamfering a glass member, the above-described polishing (grinding) tool 6 is required. Polishing (grinding) surface
6b gradually wears and changes its shape.
The grinding (grinding) action of the grinding (grinding) surface 6b on 5a changes, and as a result, the shape (chamfered shape) of each corner 5a after chamfering changes. Therefore, there is a problem that the polishing (grinding) tool 6 needs to be periodically replaced. Further, in the conventional glass member chamfering method, noise is generated when each corner 5a of the glass plate 5 is polished (ground) with the polishing (grinding) tool 6, or
There is a problem that polishing (grinding) powder of the glass is scattered, thereby deteriorating the working environment and soiling mechanical equipment. In the conventional method for chamfering a glass member, for example, when the glass member is a very thin glass plate, the polishing (grinding) tool 6 is provided at each corner of the glass plate.
There is a problem that the glass plate may be cracked or the glass plate may be broken due to the contact pressure applied to each corner when contacting the glass plate. Further, in the conventional glass member chamfering method, when the shape of the glass member is complicated, the tool 6 is moved along the shape of the glass member to chamfer the corner of the glass member. There is a problem that is difficult. The present invention has been made in view of the above-mentioned problems to solve these problems effectively. Therefore, the purpose is to eliminate the need for a grinding (grinding) tool for chamfering the corners of the glass member, generate noise, deteriorate the working environment, and contaminate mechanical equipment. Without, also, the glass member does not crack, or the glass member is not broken,
Even when the shape of the glass member is complicated and the glass member has a bent corner, the corner can be easily chamfered, and a stable chamfered shape can always be obtained. It is to provide a method for chamfering a glass member.

製品であってもよい。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the glass member chamfering method according to the present invention will be described below with reference to FIGS. 1 and 2. FIG. FIG. 1 is an explanatory view of a method of chamfering a glass member according to one embodiment of the present invention, and is a view as seen from a side surface of a flat raw glass plate 1 similar to FIG. 3 as a glass member. The glass member chamfering method according to the present embodiment is a CO 2 laser light generator (not shown) whose operation is controlled by a computer.
Is used to chamfer at least a part of the entire length of each corner 1a of the glass plate 1. The method for chamfering a glass member according to the present embodiment includes the above-described glass plate
A first step of heating the entire temperature from room temperature to a predetermined temperature, a second step of chamfering each corner 1a of the glass sheet 1, and returning the temperature of the entire glass sheet 1 from the predetermined temperature to room temperature. It consists of three stages, the third stage, which will be described in detail below. First, in the first stage, the entire glass plate 1 to be chamfered is gradually heated to a predetermined temperature lower than its softening temperature and maintained at the predetermined temperature using, for example, a heater (not shown). Next, in the second stage, the glass plate kept at the above-mentioned predetermined temperature is irradiated with the CO 2 laser beam 2 from the above-mentioned device. At this time, the irradiation spot 2a of the laser beam 2 is moved along, for example, the entire length of each corner 1a along each corner 1a while irradiating each corner 1a of the glass plate 1. At this time, for example, the laser irradiation conditions such as laser output, scanning speed, and focal position are such that the laser-irradiated corners 1a are heated to a high temperature and softened by the predetermined temperature and are rounded as shown in FIG. It is set appropriately so as to take on. Also,
During laser irradiation, the above laser irradiation conditions are kept constant. In the third stage, the entire glass plate 1 chamfered is gradually cooled from a predetermined temperature heated by the heater to a normal temperature. According to the glass member chamfering method according to the present embodiment, by irradiating the glass plate 1 with the laser beam 2,
Since chamfering can be performed over the entire length of each corner 1a, polishing (grinding) required in the conventional method is required.
No tools are required. Therefore, conventionally, the abrasion (grinding) tool is worn due to long-term use, and the chamfering action is changed. In order to prevent this, it has been necessary to replace the polishing (grinding) tool. Work becomes unnecessary. Further, according to the glass member chamfering method according to the present embodiment, each of the corners 1a is softened by heat and chamfered, and since there is no need to contact any tool with each of the corners 1a, No external force is applied to the glass plate 1. For this reason, when chamfering the corners 1a, no noise is generated, the working environment is not degraded, the mechanical equipment is not stained, and the glass plate 1 is cracked or The glass plate 1 is not damaged. Further, according to the glass member chamfering method according to the present embodiment, in the second stage, the laser beam 2 is applied to the corners 1a while maintaining the entire glass plate 1 at the predetermined temperature. Therefore, at that time, there is no sharp and large temperature rise from the predetermined temperature at each corner 1a. Therefore, cracking or breakage of the glass plate 1 due to a rapid and large temperature rise is effectively prevented. Further, according to the glass member chamfering method according to the present embodiment, the glass plate 1 is heated to a predetermined temperature by the heater until the third stage, and the glass plate 1 is gradually cooled in the third stage. Since the glass plate 1 is cooled, the glass plate 1 is effectively prevented from being cracked or damaged due to rapid cooling. Further, according to the glass member chamfering method according to the present embodiment, even when the shape of the glass member is complicated, the irradiation spot 2a can be easily formed in a corner of the glass member corresponding to the shape of the glass member. Since the glass member can be moved along the portion, the corner of the glass member can be easily chamfered. Further, according to the glass plate chamfering method according to the present embodiment, a stable chamfered shape can be always obtained by keeping the laser irradiation conditions constant. Further, according to the glass sheet chamfering method according to the present embodiment, since each of the corners 1a is formed into a rounded and curved surface,
The chamfered shape is smoother than with the conventional method. The present invention is not limited to the above-described embodiments, but may be embodied in various other forms. For example, in the above-described embodiment, the device that generates the CO 2 laser beam 2 is used to chamfer each corner 1 a of the glass plate 1. Other devices that generate laser light such that at least a portion of the energy is absorbed may be used. In the above-described embodiment, the heater is used to heat the entire glass plate 1 from room temperature to a predetermined temperature, or to return the temperature to room temperature, but the type of the heater is limited. Instead, any known type such as a nichrome wire heater and an infrared heater can be used. In the above-described embodiment, the irradiation spot 2a is moved with respect to the glass plate 1 when the glass plate 1 is irradiated with the laser beam 2. However, the irradiation spot 2a may be reversed. That is, the position of the irradiation spot 2a may be fixed, and the glass plate 1 may be moved with respect to the irradiation spot 2a. Further, in the above-described embodiment, the case where the glass member is the glass plate 1 as a material has been described, but the glass member may be a glass product manufactured based on the glass plate 1. .
