[0036] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0037] Please see Figure 1-5 As shown, this embodiment provides a diamond laser cutting device. This application is an improvement based on the invention patent with publication number CN116100169A. The main improvement is in the fixture 1.

[0038] The patent documents disclosed above reveal the following technical features:

[0039] For ease of explanation, the technical solution in this application and the aforementioned disclosed patent documents both use the three axes of the spatial coordinate system, namely the X-axis, Y-axis, and Z-axis, as references for specific explanations. The Z-axis direction can also be understood as the vertical direction or the up-down direction.

[0040] The laser head 100 is used to emit laser along the X-axis direction, and the laser emitted by the laser head 100 cuts the diamond.

[0041] The linear module drives the laser head 100 to move linearly along the Y-axis, thus creating a cutting path. Specifically, during cutting, the laser head 100 reciprocates linearly along the Y-axis under the drive of the linear module, performing reciprocating cuts on the diamond. The cutting path of the laser head 100 (which can also be considered the travel path of the laser head 100, as shown in the reference) is... Figure 1 and Figure 5 This refers to the kerf position after the diamond is cut; specifically, a servo screw linear module is preferred for linear modules.

[0042] The truss is in the shape of a long beam, located in front of the laser head 100 and extending along the Y-axis.

[0043] The fixture 1 is sequentially arranged on the truss along the Y-axis, and each truss can move between a clearance position and a cutting position relative to the truss. The fixture 1 is rotatably arranged on the truss about a rotation axis extending along the Y-axis.

[0044] It is worth noting that in the cutting position, the fixture 1 is located in the cutting path to ensure that the laser head 100 can cut the diamond when it travels along the cutting path. At this time, the fixture 1 is in a vertical state. In the avoidance position, the fixture 1 is deviated from the cutting path so that the laser head 100 will not cut the fixture 1 when it travels along the cutting path. At this time, the fixture 1 is set along the X-axis.

[0045] The diamond is fixed on fixture 1 to facilitate diamond cutting.

[0046] In this embodiment, the main improvement is to the fixture 1 so that the fixture 1 can hold diamonds of different thicknesses. During the diamond cutting process, the laser head 100 needs to move back and forth along the cutting path. After the diamond is cut, the laser will pass through the diamond and irradiate the fixture 1. The fixture 1 is subjected to heat source impact, which can easily cause damage to the fixture 1.

[0047] Specifically, in this embodiment, such as Figure 1 As shown, in the cutting position, the jig 1 has a groove 10 on the side facing the laser head 100. The groove 10 has a carrier block 2 that slides along the X-axis. The carrier block 2 includes a carrier surface 21 for contacting the diamond. The jig 1 also has a fixing member 3 on the side facing the laser head 100. The diamond is fixed on the carrier surface 21 by the fixing member 3.

[0048] In order to enable the clamping of diamonds of different thicknesses, this embodiment also includes an adjustment mechanism 4. The adjustment mechanism 4 is installed on the fixture 1 or the carrier block 2. The adjustment mechanism 4 can adjust the distance between the fixing member 3 and the carrier surface 21 so as to enable the clamping of diamonds of different thicknesses.

[0049] Specifically, such as Figure 2 and Figure 3 As shown, the adjustment mechanism 4 includes a screw 41 and a screw hole 42. The screw hole 42 is located on the carrier block 2. It is worth noting that... Figure 1 To avoid the cutting position, the axis of the screw hole 42 is set along the X-axis direction, and the screw 41 is rotatably mounted on the fixture 1. The screw 41 extends into the screw hole 42 and is threadedly connected to the screw hole 42. The side wall of the carrier block 2 abuts against the inner wall of the slide groove 10 to limit the carrier block 2 from overturning during the sliding process.

[0050] With the above configuration, since the screw 41 is rotatably connected to the fixture 1, when the screw 41 rotates, the external thread on the screw 41 and the internal thread on the screw hole 42 cooperate with each other. In the cutting state, the carrier block 2 is pushed to slide along the X-axis direction, thereby changing the relative position between the cross surface 21 and the fixing member 3, so that it can be used to place diamonds of different thicknesses.

[0051] To limit the movement of the screw 41 along the axis of the screw hole 42 on the fixture 1, in this embodiment, as follows: Figure 3 As shown, it also includes a limiting frame 12 with a C-shaped cross section and fixed on the fixture 1. The fixture 1 inside the limiting frame 12 is provided with a through hole 11 for the screw 41 to pass through. The side wall of the limiting frame 12 is provided with a plug groove 121, and a plug plate 122 can be inserted into the plug groove 121.

[0052] When it is necessary to install the screw 41, the plug plate 122 is taken out from the plug slot 121, and then the screw 41 is passed through the through hole 11. Then the screw 41 is extended into the screw hole 42 and a threaded connection is formed to realize the connection between the screw 41 and the carrier block 2.

[0053] Then, the screw 41 is pushed inward so that the nut on the screw 41 abuts against the end face of the fixture 1. Then, the insertion plate 122 is inserted into the insertion slot 121. At this time, the side wall of the insertion plate 122 abuts against the end wall of the nut on the screw 41, thereby restricting the movement of the screw 41.

[0054] In order to rotate the screw 41, such as Figure 3 As shown, the plug plate 122 is provided with a clearance hole 123 that allows a wrench to pass through.

[0055] The distance between the fixing member 3 and the cross surface 21 can be adjusted by the screw 41, so that the diamond can be placed between the fixing member 3 and the cross surface 21.

[0056] In this embodiment, the fixing member 3 can be a plate fixed on the fixture 1. The diamond can be clamped by the cross surface 21 and the fixing member 3. It is worth noting that in order to detect whether the diamond has been completely cut, the fixing member 3 is located above the cutting path in the cutting state. It can also be understood that the fixing member 3 is located on the upper side of the cut. When the diamond is completely broken, the diamond on the lower side of the cut falls down under the action of the counterweight 5, thereby realizing the detection of the diamond cutting state. At this time, the fixing member 3 and the carrier block 2 will fix the diamond on the upper side of the cut.

[0057] It is worth noting here that Figure 5 The 'a' in the text refers to diamond.

[0058] Specifically, in this embodiment, the fixing member 3 includes a fixing screw hole 31 and a fixing bolt 32. The fixing screw hole 31 is set on the fixture 1, and the fixing bolt 32 is threadedly connected to the fixing screw hole 31. By rotating the fixing bolt 32, the end wall of the fixing bolt 32 abuts against the diamond, thereby fixing the diamond on the cross surface 21. At this time, a gap will be left between the diamond and the fixture 1 so that the diamond part below the cut can fall downward.

[0059] In order to provide counterweight for the diamond below the cut, such as Figure 2 and Figure 4 As shown, the carrier block 2 is provided with a sliding groove 23. In the avoidance position, the sliding groove 23 is set along the X-axis direction. In the cutting state, the sliding groove 23 is set along the Z-axis direction. The counterweight block 5 is slidably installed in the sliding groove 23.

[0060] To improve the stability of the sliding of counterweight 5, in this embodiment, as follows: Figure 4 As shown, a guide rod 231 is fixedly installed in the sliding groove 23 along the length of the sliding groove 23. The counterweight 5 is sleeved on the guide rod 231. The counterweight 5 is also provided with a bayonet 51 for diamond insertion and a locking member 52 for locking the diamond and the counterweight 5 on one side. In the cutting state, the bayonet 51 is locked at the lower edge of the diamond. The locking member 52 is a positioning bolt. The positioning bolt is threadedly connected to the counterweight 5. By rotating the positioning bolt, the end wall of the positioning bolt abuts against the diamond, thereby fixing the counterweight 5 on the diamond below the cut so that the diamond below the cut can fall downward.

[0061] When the diamond is cut, the laser emitted by the laser head 100 can easily damage the fixture 1 and the carrier block 2. In this embodiment, for example... Figure 4 and Figure 5 As shown, the carrier block 2 has a water storage cavity 24 for storing water, in which the water is cooling water. The cooling water is used to absorb the energy of the laser emitted by the laser head 100, reducing the risk of damage to the carrier block 2.

[0062] To achieve the loading of cooling water, in this embodiment, as follows: Figure 4 As shown, the carrier block 2 is provided with a water inlet 26 to allow for the filling of cooling water. It is worth noting that in other embodiments, a water supply system 27 connected to the water storage chamber 24 can also be provided. The water supply system 27 can provide a continuous supply of cooling water to the water storage chamber 24 to achieve heat exchange between the fixture 1 and the carrier block 2.

[0063] In order to enable water to better absorb laser energy, in this embodiment, such as Figure 4 As shown, when the fixture 1 is in the cutting position, the block 2 is provided with an opening at the position where it is aligned with the cutting path, and also includes an observation window 25 that seals the opening. The observation window 25 is made of transparent material so that the laser of the laser head 100 can be shone into the water. It is worth noting that the cross-section of the observation window 25 is C-shaped or U-shaped to reduce the risk of damage to the block 2.

[0064] Since the carrier block 2 is installed inside the slide groove 10, when the laser head 100 moves along the cutting path, the laser is likely to irradiate the fixture 1 on the side of the carrier block 2, which can easily damage the fixture 1. In order to solve this problem, in this embodiment, in the cutting position, the side of the fixture 1 facing the laser head 100 is provided with a cutting avoidance groove 13 arranged along the Y-axis direction. Specifically, the projection of the cutting path of the laser head 100 on the fixture 1 along the X-axis direction falls into the cutting avoidance groove 13. The side wall of the observation window 25 is fixedly provided with a sliding block 22 extending into the cutting avoidance groove 13. The side wall of the sliding block 22 is slidably connected to the side wall of the cutting avoidance groove 13, which further realizes the stable sliding of the carrier block 2. At the same time, in the cutting position, the sliding block 22 can slide along the X-axis direction in the cutting avoidance groove 13. The sliding block 22 blocks the side wall of the cutting avoidance groove 13 away from the laser head 100, reducing the risk of the laser damaging the fixture 1.

[0065] It is worth noting that since the sliding block 22 is installed on the observation window 25, which is in contact with the water in the water storage chamber 24, the heat of the sliding block 22 can be transferred to the water through the observation window 25, thus greatly reducing the risk of the sliding block 22 being damaged.

For example, the steps described in this disclosure can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
