Description

Technical Field

[0001] The utility model belongs to the technical field of diamond detection, and in particular relates to a finished product detection device used for diamond processing. Background Art

[0002] Diamond is known as the hardest substance in the world. It has very special and extraordinary physical, mechanical and optical properties. At the same time, diamond also has excellent thermal conductivity. Unlike metals that rely on peripheral electrons for heat transfer, diamond relies on phonons. When the composition of the material is simpler, the structure is simpler, and the impurities are fewer, the phonon movement is faster and the heat transfer rate is faster. The thermal conductivity of diamond is applied to material engineering: such as solar energy collection systems, air cleaning equipment, engine coolers, etc. Since the thermal conductivity of diamond is more than 1,000 times higher than that of steel, it has high plasticity and can be used to make efficient heat conduction materials to improve the efficiency of equipment. However, since artificial diamonds are doped with some impurities and metal particles during the early and synthetic process, the thermal conductivity of diamonds is reduced by the influence of impurities. At present, when testing the thermal conductivity of diamonds, they need to be placed and inspected manually one by one. The operation is complicated and time-consuming, resulting in low efficiency in the thermal conductivity detection of diamonds. Utility Model Content

DETAILED DESCRIPTION

[0016] See also Figure 1-Figure 4 The utility model provides the following technical solutions: it includes a rotating ring 1, a plurality of limit grooves 11 are opened on the top, a plurality of through holes 12 are opened in the rotating ring 1, the plurality of through holes 12 correspond to the plurality of limit grooves 11 in position, two bearing plates 2 for supporting diamonds are hingedly connected to the inner walls of the plurality of through holes 12, temperature sensors 21 for detecting diamonds are installed on the tops of the two bearing plates 2, a torsion spring 22 is arranged between the bearing plates 2 and the inner walls of the corresponding through holes 12, a bearing cover 3 is rotatably connected to the outer side of the rotating ring 1, two clearance holes 31 are arranged on the side wall of the bearing cover 3, and a heating plate 4 for heating diamonds is arranged on the top of the rotating ring 1.

[0017] In this embodiment: the rotating ring 1 is annular in design, and a plurality of limiting grooves 11 and a plurality of through holes 12 are evenly distributed on the rotating ring 1. The bearing cover 3 wraps and limits the bottom end and the side wall of the rotating ring 1, thereby realizing the protection of the rotating ring 1 and preventing the diamonds entering the rotating ring 1 from escaping during the rotation process. The bearing cover 3 drives the rotating ring 1 to rotate through the internal motor, and the bearing cover 3 remains in a fixed state, so that the positions of the plurality of limiting grooves 11 and the through holes 12 on the rotating ring 1 can be changed and adjusted. The bearing cover 3 transmits the diamonds through two transmission tracks, and passes the diamonds through the corresponding clearance holes 31 through one of the transmission tracks, and then guides them into one of the limiting grooves 11. At this time, the bearing plate 2 supports the bottom end of the diamond, and the torsion spring 22 pushes the corresponding bearing plate 2 to rotate, so that the bearing plate 2 can flip upward and maintain a vertical state with the inner wall of the through hole 12. The state is convenient for the carrier plate 2 to support the diamond. After the rotation of the rotating ring 1, the diamond in the limit groove 11 is moved to another corresponding transmission track position. At this time, the heating plate 4 is located at the top of the diamond. By controlling the heating plate 4 to contact with the top of the diamond, the heating plate 4 squeezes the diamond. The heating plate 4 outputs heat and outputs it for a fixed time. The high thermal conductivity of the diamond is used to transfer the temperature to the temperature sensor 21 above the carrier plate 2. The temperature sensor 21 detects the temperature of the diamond. When the detected temperature is lower than the set standard, the carrier plate 2 is controlled to flip downward to put the defective diamond into the collection device below. If the temperature reaches the standard, it means that the impurities in the diamond are less. Then the qualified diamond is transferred to the corresponding transmission track. There is no need to place and inspect them one by one manually. The operation is simple and time-consuming, thereby improving the efficiency of diamond thermal conductivity detection.

[0018] The top of the bearing cover 3 is fixedly connected to the limiting inner cover 32, and the limiting inner cover 32 is slidably connected to the inner wall of the rotating ring 1; the bearing cover 3 supports the limiting inner cover 32, and the limiting inner cover 32 blocks and limits the inner wall of the rotating ring 1 to prevent the diamond from escaping from the limiting inner cover 32 during rotation, causing the diamond to be missed.

[0019] A first telescopic rod 33 for pushing the diamond is installed in the bearing cover 3, and the first telescopic rod 33 does not contact the bearing plate 2; the first telescopic rod 33 pushes the diamond that has passed the inspection, and a through hole corresponding to the output end of the first telescopic rod 33 is opened on the limiting inner cover 32, so that the output end of the first telescopic rod 33 can enter the internal space of the limiting groove 11 to push the diamond, so that the diamond that has passed the inspection can enter the corresponding transmission track for the next process.

[0020] A second telescopic rod 41 is fixedly connected to the top of the heating disk 4, and a support plate 42 is fixedly connected to the top of the second telescopic rod 41, and the support plate 42 is fixedly connected to one side of the limiting inner cover 32; the limiting inner cover 32 supports the support plate 42, and the support plate 42 supports the second telescopic rod 41, and the second telescopic rod 41 supports and drives the heating disk 4. When the rotating ring 1 drives the diamond to rotate, the second telescopic rod 41 drives the heating disk 4 to shrink beyond the height of the rotating ring 1, thereby preventing the heating disk 4 from causing movement obstacles to the rotating ring 1. When the diamond detection is unqualified, the second telescopic rod 41 extends downward to drive the heating disk 4 to squeeze the diamond, and the diamond squeezes the corresponding two supporting plates 2 in the downward direction, so that the supporting plate 2 can be flipped downward. At this time, the supporting plate 2 no longer limits the diamond, so that the diamond enters the defective product collection device.

[0021] A plurality of feed tubes 5 are provided at the bottom end of the rotating ring 1, and the plurality of feed tubes 5 correspond to the plurality of through holes 12 one by one, and the plurality of feed tubes 5 are fixedly connected through a collecting bin 51; when defective diamonds enter the corresponding through holes 12, the diamonds then slide into the feed tubes 5, and the feed tubes 5 guide the unqualified diamonds into the collecting bin 51 for collection and storage, so that the defective diamonds can be distinguished and processed centrally.

[0022] The working principle and use process of the utility model are as follows: when the diamond is tested, the diamond is passed through the corresponding clearance hole 31 through one of the transmission tracks, and then guided into one of the limit grooves 11, the rotating ring 1 is controlled to rotate, and the rotating ring 1 drives the diamond to rotate, so that the diamond in the limit groove 11 is moved to the corresponding position of another transmission track. At this time, the heating plate 4 is located at the top of the diamond, and the second telescopic rod 41 is controlled to drive the heating plate 4 to move downward and contact the top of the diamond. The heating plate 4 is fixed to output heat and output time, and the high thermal conductivity of the diamond is used to transfer the temperature to the carrier. On the temperature sensor 21 above the plate 2, when the detected temperature is lower than the set standard, the second telescopic rod 41 extends downward to drive the heating plate 4 to squeeze the diamond, and the diamond squeezes the corresponding two supporting plates 2 in the downward direction, so that the supporting plate 2 can be flipped downward. At this time, the supporting plate 2 no longer limits the diamond, so that the diamond enters the defective collection device. If the temperature reaches the standard, the output end of the first telescopic rod 33 is controlled to enter the internal space of the limiting groove 11 to push the diamond, so that the qualified diamond can enter the corresponding transmission track for the next process.
