Detailed Description
The technical solution of the present invention will be further described in more detail with reference to the following embodiments. It is to be understood that the described embodiments are merely a few embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Brittle materials are materials that break with only a small amount of deformation under an external force (e.g., tension, impact, etc.). The brittle materials commonly used are cast iron, ceramics, stone, glass, sapphire, etc. The brittle material has the characteristics of high compressive strength, difficult bearing of tensile force, no plastic deformation after stress and brittle fracture when being damaged. Based on the above characteristics, during the mechanical processing (such as polishing) of the brittle material by the prior art, the edge tends to form micro cracks, which may eventually cause damage and loss of the brittle material. It is therefore necessary to reduce the cracking of the edges of brittle materials by technical means.
Referring to fig. 1, fig. 1 is a schematic structural diagram of a brittle material edge thermal polishing apparatus according to the present invention. The brittle material edge thermal polishing apparatus 100 includes a heating fixture 110, a heat source generator 120 and a supporting base 130, and is used for polishing the edge surface of the brittle material 101.
The heating fixture 110 is a three-dimensional structure and includes at least one heating plane 111 and an accommodating groove 112. The accommodating groove 112 is used for accommodating a portion of the edge of the brittle material 101, and the heating fixture 110 can move relative to the edge of the brittle material 101. The thickness of the brittle material 101 is set to be smaller than the width of the accommodating groove 112, so that when part of the edge of the brittle material 101 is placed in the accommodating groove 112, the contact with the inside of the groove body of the accommodating groove 112 is avoided. The brittle material 101 is horizontally fixed on a supporting seat 130, and the supporting seat 130 provides a plane for supporting the brittle material 101. In this embodiment, the plane area of the support 130 for supporting the brittle material 101 is smaller than the area of the brittle material 101, so that the central portion of the brittle material is in contact with the support 130, the support 130 is a vacuum chuck, and the vacuum chuck adsorbs the central portion of the brittle material 110. The edge of the holding groove is in a suspended state and can be placed in the holding groove 112 without contacting with the groove body of the holding groove 112. The heat source generator 120 generates heat and applies the heat directly to the heating plane 111 to increase the temperature of the heating jig 110.

In the present embodiment, three adjacent surfaces of the cubic structure are provided inward of the receiving groove 112, and the remaining three surfaces are all the heating surfaces 111. A rectangular parallelepiped structure is cut from one surface of the heating fixture 110 to the opposite surface to form a receiving groove 112, and the cross-sectional structure of the heating fixture 110 is concave. The cut-out structure is not limited to a rectangular parallelepiped, and may be a circular arc shape or the like at the bottom of the accommodating groove 112, that is, the bottom of the accommodating groove 112 may be provided according to the structure of the edge of the brittle material 101, as shown in fig. 2 and 3. Taking the heating fixture 110 with the concave structure as an example, in the cubic structure, three surfaces which are not contacted when the cuboid structure is cut off are all heating planes 111, at this time, three heat source generators 120 are provided to heat the heating fixture 110 from three different directions by the three heating planes respectively.

A driving motor 150 is provided, and the driving motor 150 is connected to the heating fixture 110 to drive the heating fixture 110 to move along the edge of the brittle material 101. The heating fixture 110 is supported by other supporting structures, so that the distance between the interior of the groove body of the accommodating groove 112 and the surface of the brittle material 101 is always kept constant. The distance of the groove body 112 from the edge of the brittle material 101 may be in the order of micrometers, but it is necessary to ensure that there is no contact. The driving motor 150 controls the heating fixture 110 to stay at a certain position of the edge of the brittle material 101, the heat source generator 120 heats the heating plane 111 for a set time, and then the polishing process is completed at the position, at this time, the driving motor 150 controls the heating fixture 110 to move, and the operation is repeated when the unprocessed edge position is reached, until the thermal polishing process of the edge of the brittle material 101 is completed. The driving motor 150, the heat source controller 140, and the heat source generator 120 all generate electricity to operate by the same power source.
