[0026] The utility model will be further described in detail in combination with the embodiment of the drawings.

[0027] AsFigures 1-4 The diagram shows a preferred embodiment of the present invention. The diamond processing apparatus of this embodiment includes a base 1, a mounting base 2, a moving mechanism 4, and a cover 5. The base 1 has a fixed seat 11 for holding the diamond to be processed, such that the surface to be cut is positioned opposite the XY plane in the horizontal direction. The mounting base 2 is located on the base 1 and maintains a preset distance from it. The mounting base 2 has a focusing lens barrel 32 for mounting a focusing lens 31. After transmission, the laser beam used to process the diamond passes through the focusing lens 31 and is focused. The moving mechanism 4 is mounted on the base 1 and allows the fixed seat 11, along with the diamond to be processed, to move along the XY plane of the base 1, directing the laser beam vertically downwards along the Z-axis perpendicular to the XY plane to irradiate and cut the surface of the diamond. The cover 5 surrounds the dust particles generated during the cutting process.

[0028] Specifically, such as Figure 2 As shown, the bottom of the cover 5 has an opening 51 for the fixing seat 11 to pass through. The edge of the opening 51 of the cover 5 surrounds the fixing seat 11 and rests on the base 1. The top of the cover 5 has a first opening 52 for the focusing lens tube 32 to extend into. The cover 5 only surrounds the fixing seat 11 inside the cover 5, while other moving mechanisms 4, base 1, and mounting base 2 are all located outside the cover 5. This reduces the space inside the cover 5, limits the range of dust particles generated during the cutting process, and facilitates the discharge of dust particles from the discharge port 54, which can improve the dust particle removal efficiency to a certain extent. However, due to the reduced space of the cover 5, when the cover 5 is placed on the base 1, the cover 5 will move with the base 1 in the XY plane of the base 1. If the first opening 52 and the focusing lens tube 32 also move with the cover 5, it will change the focusing position of the laser beam and affect the processing of the diamond to be processed. Therefore, in this embodiment, the cover 5 is at least partially a flexible segment 53b. Specifically, the cover includes a peripheral wall 53 extending upward from its outer edge at the bottom. The peripheral wall 53 includes an upper segment and a lower segment 53a. The flexible segment 53b is located in the upper segment, and the first opening 52 is located above the flexible segment 53b. The flexible segment 53b converts the movement of the fixed seat 11 along the XY plane of the base 1 into the bending and / or stretching of the flexible segment 53b, thus keeping the position of the first opening 52 constant. The flexible segment 53b includes a plurality of continuous "V"-shaped folding grooves. The two ends of the "V"-shaped folding grooves can move closer or further apart, thereby realizing the stretching and / or bending of the flexible segment 53b. When the lower segment 53a of the peripheral wall 53 moves with the moving mechanism 4, the part of the flexible segment 53b connecting to the lower segment 53a also moves. At this time, the flexible segment 53b will bend and / or stretch, preventing the movement of the moving mechanism 4 from being transmitted to the top of the cover 5, thus keeping the position of the first opening 52 constant.

[0029] In order to expel dust particles from inside the enclosure 5, such as Figures 1-3 As shown, in this embodiment, the lower section 53a of the peripheral wall 53 is provided with an outlet 54 for discharging dust particles generated during the cutting process from the cover 5. The outlet 54 is connected to a dust collector located outside the cover 5. Furthermore, the lower section 53a of the peripheral wall 53, excluding the outlet 54, is provided with a second opening 55 for the operator to place and retrieve the diamond to be processed, and a switch 56 for opening and closing the second opening 55. (See Figure 53) Figure 4 In this embodiment, the switch 56 is plate-shaped. A handle 57 is provided adjacent to the flexible section 53b to facilitate opening or closing the second opening 55. When the switch 56 opens the second opening 55, the operator can place or remove the diamond; when the switch 56 closes the second opening 55, the cover 5 is in a closed state, thus enclosing the dust particles generated during the cutting process.

[0030] The diamond processing apparatus of this embodiment also includes an adjustment mechanism 6 for adjusting the focusing lens barrel 32, which is located outside the top of the housing 5. (See attached image) Figures 5-6 The focusing lens barrel 32 is connected to the mounting base 2 via a connecting seat 33. The connecting seat 33 includes an actuating part 331 for the adjustment mechanism 6 to operate. The adjustment mechanism 6 acts on the actuating part 331 to allow the focusing lens barrel 32 to move along the XY plane of the base 1, and the focusing lens barrel 32 can extend into the housing 5 through the first opening 52. In this embodiment, the adjustment mechanism 6 includes an elastic element and an adjusting screw 62. The elastic element is a compression spring 61, with its fixed end 61a fixed to the mounting base 2 and its free end 61b abutting against the actuating part 331. The compression spring 61 acts on the actuating part 331, causing the connecting base 33 to always have a tendency to move along the direction of the elastic force. The adjusting screw 62 also acts on the actuating part 331 and in the opposite direction to the action of the compression spring 61. The mounting base 2 is provided with a screw hole 21 through which the adjusting screw 62 passes. The adjusting screw 62 can move within the screw hole 21 and drive the connecting base 33 to move in the direction of the compression spring 61. When the adjusting screw 62 moves toward the compression spring 61, the connecting seat 33 also moves toward the compression spring 61 under the push of the adjusting screw 62; when the adjusting screw 62 is rotated in the opposite direction to move away from the compression spring 61, the connecting seat 33 also moves away from the compression spring 61 under the elastic force of the compression spring 61. In this embodiment, the adjusting mechanism 6 is provided in two sets, respectively arranged along the X-axis and Y-axis directions of the base 1, so as to realize that the focusing lens barrel 32 moves along the XY plane of the base 1 to adjust the focusing position of the laser beam before the diamond processing device starts processing.

[0031] In summary, the working process of the diamond processing apparatus in this embodiment is as follows:

[0032] The operator pulls the handle 57, the switch piece 56 rotates and opens the second opening 55, fixes the diamond to be processed on the fixing seat 11, rotates the switch piece 56 to close the second opening 55 after the fixing is completed, adjusts the adjusting mechanism 6 to make the focal point of the laser beam act on the diamond to be processed and then starts the processing. During the processing, the moving mechanism 4 controls the fixing seat 11 to move in the preset track, at the same time, the bottom of the cover body 5 also moves with the fixing seat 11, and since the upper section of the peripheral wall 53 of the cover body 5 is the flexible section 53b, when the moving motion of the moving mechanism 4 is transmitted to the flexible piece, it is converted into the bending and / or stretching of the flexible piece, and the first opening 52 above the flexible section 53b and the position of the focusing lens barrel 32 partially extending into the cover body 5 always remain unchanged during the processing, so that the laser beam vertically downward along the Z axis perpendicular to the XY plane to irradiate and cut the cutting surface of the diamond to be processed. After the cutting is completed, the second opening 55 is opened, the processed diamond is taken out and put into the next diamond to be processed, and the next processing is entered.
