Technical Field
[0001] The utility model relates to the technical field of sapphire crystal rod detection, in particular to an auxiliary device for sapphire crystal rod defect detection. Background Art
[0002] Sapphire is gradually penetrating into high-end fields. As lighting sources develop towards the fourth-generation green new energy LED, lighting sources need to be more energy-saving, environmentally friendly and green. Sapphire, as a key base material for lighting sources, requires strict quality control. Its quality control becomes particularly important. However, artificial sapphire has deficiencies in production technology and processing technology, resulting in defects that cannot be completely eradicated. It is necessary to perform internal defect detection on the processed sapphire crystal rods.
[0003] The existing technology usually uses optical detection, using light to observe the state of the transmitted light to determine whether the crystal rod has defects. During the detection, the crystal rod needs to be rotated or moved, and the transmitted light needs to be accurately observed. Therefore, we propose an auxiliary device for sapphire crystal rod defect detection. Utility Model Content
[0004] The purpose of the utility model is to provide an auxiliary device for sapphire crystal rod defect detection. By arranging guide rollers and support rollers that can be driven to rise and fall on both sides above the base, the crystal rod can be driven to move left and right so that the area to be tested is placed above the regular hexagonal prism. The support rollers are used to support and drive the crystal rod to rotate, so that light can be transmitted through the crystal rod to illuminate downward, and color cards of different colors can be used for comparison, so that the transmitted light can be more accurately observed to determine whether the sapphire crystal rod has defects, thereby solving the problems raised in the background technology.
[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an auxiliary device for sapphire crystal rod defect detection, comprising a base, a first electric push rod and a second electric push rod, wherein the first electric push rod is provided with two and vertically installed on both sides of the middle position of the base, and the second electric push rod is provided with two installed above the base on the outside of the first electric push rod; a first lifting plate is fixed on the top of the first electric push rod, and support rollers are installed laterally and rotatably on the front and rear ends of the surface of the first lifting plate, and a second lifting plate is fixed on the top of the second electric push rod, and guide rollers are installed longitudinally and rotatably on the surface of the second lifting plate; a regular hexagonal prism is installed laterally and rotatably above the base between the first electric push rods through a fixed plate, and color cards of different colors are fixed on the six surfaces of the regular hexagonal prism.
[0006] By adopting the above technical solution, the sapphire crystal rod is first supported transversely and placed above the guide rollers. The guide rollers can drive the crystal rod to move so that the area to be tested is placed above the regular hexagonal prism. The crystal rod is then supported transversely above the support rollers at the front and rear ends on both sides. The crystal rod can rotate and allow light to pass through. By facing the color cards of different colors upward, accurate comparison is facilitated to determine whether the crystal rod has defects.
[0007] Optionally, the middle positions on both sides of the regular hexagonal prism are connected with rotating shafts, and the regular hexagonal prism is rotatably connected to the surface of the fixed plate through the rotating shafts on both sides.
[0008] By adopting the above technical solution, the rotatable installation of the regular hexagonal prism is achieved through the rotatable connection between the rotating shaft and the fixed plate.
[0009] Optionally, the rotating shaft on the side of the regular hexagonal prism is rotatably connected to the fixed plate via a damping bearing, and the damping bearing is embedded in the surface of the fixed plate.
[0010] By adopting the above technical solution, the damping bearing enables the regular hexagonal prism to be rotatably connected to the fixed plate through the rotating shaft. After it is driven to rotate, the damping bearing can lock the angle and it will not rotate.
[0011] Optionally, the outer ring of the guide roller is provided with an arc groove, and the arc groove surrounds the outer ring of the guide roller.
[0012] By adopting the above technical solution, the sapphire crystal rod support is placed in the arc groove of the outer ring of the guide roller and is stably supported.

[0014] By adopting the above technical solution, it is ensured that the supporting rollers on both sides can be raised and lowered synchronously, thereby ensuring the lateral state of the sapphire crystal rod during the process.
[0015] Optionally, the second electric push rods on both sides of the regular hexagonal prism have the same height, and the guide rollers on both sides have the same height.
[0016] By adopting the above technical solution, it can be ensured that the guide rollers on both sides can be raised and lowered synchronously, and the lateral state of the sapphire crystal rod can be guaranteed during the process.
[0017] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0018] 1. The technical solution of the present application is to arrange guide rollers and support rollers that can be driven to rise and fall on both sides of the upper part of the base, so as to drive the crystal rod to move left and right so that the area to be tested is placed above the regular hexagonal prism, and to support and drive the crystal rod to rotate by supporting the support rollers, so that light can pass through the crystal rod to shine downward, and color cards of different colors can be used for comparison, so as to more accurately observe the transmitted light and judge whether the sapphire crystal rod has defects.
[0019] 2. The technical solution of the present application enables a regular hexagonal prism to be rotatably mounted between the fixed plates on both sides by means of a damping bearing. After the regular hexagonal prism is rotated so that the required color card faces upward, the damping bearing can be used to prevent the regular hexagonal prism from rotating to achieve the purpose of locking the color card position.

[0025] See also Figure 1-3 The utility model provides a technical solution: an auxiliary device for sapphire crystal rod defect detection, comprising a base 1, a first electric push rod 2 and a second electric push rod 3, wherein two first electric push rods 2 are provided and vertically installed on both sides of the middle position of the base 1, and the first electric push rods 2 on both sides have the same height, and a first lifting plate 21 is fixed on the top of the first electric push rod 2, and support rollers 211 are installed laterally and rotatably on the front and rear ends of the surface of the first lifting plate 21, and the support rollers 211 on both sides have the same height, so that the crystal rod can be supported only between the support rollers 211 at the front and rear ends of both sides, and the rotation of the support rollers 211 can drive the sapphire crystal rod to rotate.
[0026] The second electric push rod 3 is provided with two bases 1 installed on the outside of the first electric push rod 2. The second electric push rods 3 on both sides have the same height. A second lifting plate 31 is fixed on the top of the second electric push rod 3. A guide roller 311 is longitudinally rotatably installed on the surface of the second lifting plate 31. The guide rollers 311 on both sides have the same height. Arc grooves 312 are provided on the outer rings of the guide rollers 311. The arc grooves 312 surround the outer rings of the guide rollers 311, so that the sapphire crystal rod can be laterally supported only in the arc grooves 312 of the guide rollers 311 on both sides. The rotation of the guide rollers 311 can move the crystal rod left and right in the lateral direction to adjust the position.
[0027] A regular hexagonal prism 4 is installed above the base 1 between the first electric push rods 2 on both sides in a horizontally rotatable manner through a fixed plate 11, and a rotating shaft is connected to the middle position of both sides of the regular hexagonal prism 4. The regular hexagonal prism 4 is rotatably connected to the surface of the fixed plate 11 through the rotating shafts on both sides, and the rotating shafts on the sides of the regular hexagonal prism 4 are rotatably connected to the fixed plate 11 through damping bearings 42, and the damping bearings 42 are embedded in the surface of the fixed plate 11. Color cards 41 are fitted and fixed on the six surfaces of the regular hexagonal prism 4, and each color card 41 has a different color, including at least a pure white color card 41, so that the area to be tested of the sapphire crystal rod is placed directly above the regular hexagonal prism 4, and then the regular hexagonal prism 4 is rotated so that the color card 41 to be compared faces directly upward and is locked by the damping bearings 42, so that the optical fiber that is irradiated can illuminate the surface of the color card 41, thereby comparing the colors to determine whether there are defects.
[0028] When in use, the first electric push rod 2 and the second electric push rod 3 are both connected to the control device and powered on. The first step: first, the first electric push rod 2 drives the first lifting plate 21 and the structure above it to descend, and the second electric push rod 3 drives the second lifting plate 31 and the structure above it to rise, so that the sapphire crystal rod can be supported horizontally above the guide rollers 311 on both sides and placed in the arc groove 312. The rotation of the guide rollers 311 can drive the crystal rod to move left and right, so that the position to be detected is placed above the regular hexagonal prism 4; the second step: then the second electric push rod 3 drives the second lifting plate 31 and the structure above it to descend, and the first electric push rod 2 drives the second lifting plate 31 and the structure above it to rise. The first lifting plate 21 and the structure above it are raised to a certain height. The crystal rod is supported between the support rollers 211 at the front and rear ends of both sides. Light can be irradiated from above. After the light passes through the crystal rod, it is printed on the color card 41 on the surface of the regular hexagonal prism 4. By observing the state of the light transmitted on the surface of the color card 41, it can be determined whether the crystal rod has defects. In the process, the crystal rod is rotated under the rotation and guidance of the support roller 211, and light transmission detection is performed at multiple angles. In order to obtain a more accurate detection effect, the regular hexagonal prism 4 can also be rotated so that the color cards 41 of other colors face upward and are observed. Under the comparison of multiple background colors, a more accurate result can be obtained. After that, the operation of the first step can be repeated to change the left and right position of the crystal rod above the regular hexagonal prism 4, and then the second step can be performed for detection.
