Description

Technical Field

[0001] This invention relates to the technical field of laser cutting, specifically to a laser cutting device for diamond processing. Background Technology

[0002] When laser cutting machines are used for cutting diamond wafers, their core working principle involves using an ultrafast pulsed laser to convert electrical energy into a laser beam with extremely high instantaneous power. This beam is then focused into a micron-sized ultra-high peak energy spot by a precision optical system, acting on the diamond surface to cause instantaneous ablation or phase transformation. Simultaneously, a coaxially jetted inert auxiliary gas rapidly removes microscopic particles from the kerf. The entire process, under the precise motion control of a computer numerical control system, ultimately achieves micron-level precision cutting and shaping of the diamond wafer.

[0003] Existing equipment requires manual removal of the finished product from the platform and placement of the wafer to be processed after cutting. Due to the thinness of the wafer and its suspended bottom, gripping it is difficult. If the initial retrieval fails, the operating posture must be repeatedly adjusted, thus extending the material changeover time. Ultimately, the excessively high proportion of non-cutting time restricts overall production efficiency. Therefore, a laser cutting device for diamond processing that facilitates unloading and loading is proposed. Summary of the Invention

[0004] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a laser cutting device for diamond processing, which features rapid replacement of the processed discs, effectively solving the problem of inconvenient handling of the finished product after cutting.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the present invention provides the following technical solution: a laser cutting device for diamond processing, comprising a housing, a cover connected to the housing, a slide block slidably connected to the housing, a platform mounted on the top of the slide block, a clamping assembly mounted on the platform, and a displacement assembly mounted on the top of the housing. A loading and unloading assembly is mounted on the top of the slide block, comprising: a base, mounted on the top of the housing, with a motor mounted on the top of the base; a turntable, rotatably connected to the base, the outer wall of the turntable having a toothed structure, and the output shaft of the motor having a gear with a meshing toothed structure; a frame, mounted on the top of the turntable, with a plate mounted on the frame; and a second motor, mounted on the bottom of the plate, with a slider second threadedly connected to the output shaft of the second motor, the slider second being slidably connected to the plate, and a support plate mounted on the slider second. The rotation of the turntable is responsible for the workpiece's position switching, allowing it to switch between the processing position and the window position; while the vertical movement of the support plate enables precise positioning and transfer of the workpiece on the clamping assembly.

[0007] Furthermore, the frame includes: a support frame; the support frame is fixed to the top of the base; a crossbar; the crossbar is rotatably connected to the support frame, and support blocks are connected to both ends of the crossbar, with the support blocks fixedly connected to the plate. Furthermore, the clamping assembly is equipped with a transmission assembly, which, as the plate continues to rise and connects to the transmission assembly, converts the rising force into torque, thereby controlling the clamping assembly to release the workpiece.

[0008] Furthermore, the clamping assembly includes: a frame, which is fixed to the top of the platform, and a limit block is slidably connected to the inner side wall of the frame; and a screw, which is threadedly connected to the limit block.

[0009] Furthermore, the transmission assembly includes: a transmission box, which is fixed to the inner side wall of the frame; a rod body is sleeved on the outer side wall of the screw, and a gear is fixed on the outer side wall of the rod body; a rack, which is slidably connected to the transmission box and passes through the transmission box; a spring-loaded component is provided on the rack; a rod body is fixed to the bottom end of the rack; and the rack is meshed with the gear.

[0010] Furthermore, the rebound assembly includes: a spring, which is sleeved on the outer wall of the rack, and both ends of the spring are fixed with rings; a baffle plate, which is rotatably connected to the rings, and a screw rod is fixed to the top of the rack, which is threadedly connected to the baffle plate.

[0011] Furthermore, a protrusion is fixed to the outer wall of the screw, and a groove that matches the protrusion is provided on the rod body.

[0012] Furthermore, the displacement component includes: a gantry slide, which is fixed to the top of the housing, and a slider is slidably connected to the gantry slide; and a cylinder, which is fixed to the gantry slide, and a laser cutting head is fixed to the output end of the cylinder.

[0013] Furthermore, the bottom end of the plate is provided with two liquid inlet pipes, which are connected to the support plate. The support plate has a cavity inside, and the two support plates are connected by a connecting pipe, which is fixedly connected to the slider.

[0014] Furthermore, an air pipe is fixed to the bottom of the support plate, the air pipe passes through the support plate, and an adsorption port is opened at the top of the support plate, which is connected to the air pipe.

[0015] (III) Beneficial Effects

[0016] Compared with the prior art, the present invention provides a laser cutting device for diamond processing, which has the following advantages: 1. This laser cutting device for diamond processing, after the workpiece is laser-cut, drives a turntable to rotate via motor one, moving a support plate below the workpiece. Then, motor two starts, causing slider two and the support plate to rise vertically, bringing the support plate into contact with the bottom of the workpiece and providing stable support. At this point, the clamping assembly releases its grip on the workpiece. Supported by the support plate, the workpiece rotates with the turntable to the window position, allowing operators to quickly remove the finished product and place the wafers to be processed. The entire unloading and loading process eliminates the need for direct manual contact with the wafers, avoiding the difficulty of gripping due to the thinness and suspended bottom of the wafers, thus shortening the single material changeover time and improving overall production efficiency.

[0017] 2. In this laser cutting device for diamond processing, after the laser cutting of the workpiece is completed, the operator places the workpiece to be processed on the support plate at the window position. The frame structure causes the plate at the other end to rise. During the rise, the transmission component is activated, converting the lifting force into torque, which in turn controls the clamping component to release the workpiece. Supported by the support plate, the workpiece rotates with the turntable to the window position, allowing the operator to quickly remove the finished product.

[0018] 3. In this laser cutting device for diamond processing, after the workpiece is guided onto the support plate, the coolant is controlled to be introduced into the support plate. The coolant flows into the cavity of the support plate through the inlet pipe, which cools the workpiece and prevents the workpiece from deforming or being damaged due to the high temperature generated by laser cutting.

[0019] 4. This laser cutting device for diamond processing features an air pipe at the bottom of the support plate connected to the suction port, enabling vacuum suction. This makes the workpiece more stable on the support plate, preventing displacement during rotation or movement, thereby improving processing accuracy and stability. Cooling and fixing functions are integrated into one unit, simplifying the device's structure, reducing manufacturing costs, and facilitating unified control and adjustment by operators.

[0020] 5. In this laser cutting device for diamond processing, after the workpiece to be processed is inserted into one end of the frame, the other end can be filled with the workpiece to be processed using a robotic arm or manually. Because the processed workpiece is relatively lightweight, injecting cooling water into the support plate after processing balances both ends of the support frame, effectively preventing tilting or instability caused by weight differences, thus ensuring the stability and reliability of the device during continuous operation.

[0021] 6. The laser cutting device for diamond processing can be equipped with a waste collection box located between two plates on the frame. During workpiece processing, the collection box is rotated and placed below the processing area. Waste and debris generated during laser cutting can fall into the collection box for easy centralized cleaning and disposal. Attached Figure Description

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] As attached Figure 1 and 2As shown, this embodiment provides a laser cutting device for diamond processing, including a housing 100, a cover 110 connected to the housing 100, a slide 120 slidably connected to the housing 100, and a platform 130 disposed on the top of the slide 120, which is fixed by bolts or welding, for example; the platform 130 has a "U" shaped cross-section. It should be noted that the slide 120 is driven by a linear slide, such as a ball screw linear slide or a synchronous belt linear slide.

[0026] As attached Figure 1 and 2 As shown, observation windows are provided on both sides of the enclosure 110 for users to observe the internal situation. A window is also provided on one side of the enclosure 110 near the workpiece replacement area, and a protective door can be installed at the window. The window facilitates workpiece replacement for the user. Users can monitor the internal working status of the device at any time through the observation windows, promptly identifying potential problems such as cutting accuracy or the presence of abnormal sparks. They can also easily open the protective door when workpiece replacement is needed, quickly and safely completing the workpiece replacement operation, effectively improving work efficiency while ensuring the personal safety of operators and reducing the risks associated with direct contact with the device's interior. The protective door is not shown in the attached diagram and is considered prior art, so it will not be described further here.

[0027] As attached Figure 1 and 2 As shown, a displacement assembly 200 is provided on the top of the housing 100. The displacement assembly 200 includes a gantry slide 210 and a cylinder 230. The gantry slide 210 is fixed to the top of the housing 100, and a slider 220 is slidably connected to the gantry slide 210. The cylinder 230 is fixed to the gantry slide 210, and a laser cutting head 240 is fixed to the output end of the cylinder 230. The gantry slide 210 is the moving part for laser cutting. Its principle is: through a high-rigidity mechanical structure, a precision servo drive system, and closed-loop feedback control, high-precision synchronous movement of the laser cutting head 240 on the X / Y axes is achieved, ensuring the accuracy and stability of the cutting trajectory. The cylinder 230 can drive the laser cutting head 240 to move on the Y axis. In this embodiment, the gantry slide 210 is prior art and will not be described in detail here.

[0028] As attached Figure 2As shown, the clamping assembly 300 is provided on the platform 130. Multiple clamping assemblies 300 are set according to the user's site conditions and needs. The clamping assembly 300 includes a frame 310 and a screw 340. The frame 310 is fixed to the top of the platform 130. A through groove is opened on the top of the platform 130 in the clamping area of ​​the frame 310 to prevent the laser cutting head 240 from cutting the platform 130 during cutting. A limit block 320 is slidably connected to the inner side wall of the frame 310. The screw 340 is threadedly connected to the limit block 320. By rotating the screw 340, the limit block 320 can be driven to slide on the inner side wall of the frame 310. Thus, the position of the limit block 320 can be flexibly adjusted according to the diamond workpiece of different sizes to achieve effective clamping of the diamond workpiece. The inner wall of the frame 310 has two inclined surfaces that are tangent to the outer wall of the workpiece. One side of the limiting block 320 has an arc-shaped surface near the workpiece, which fits against the workpiece and can form a tighter fit with the workpiece, effectively increasing the contact area.

[0029] In use, the workpiece to be cut is placed on the inner wall of the frame 310. By rotating the screw 340, the limiting block 320 can slide on the inner wall of the frame 310, so that the limiting block 320 clamps the workpiece. The displacement component 200 is activated, and the cylinder 230 drives the laser cutting head 240 to move to a suitable position in the Y-axis direction. The gantry slide 210 drives the laser cutting head 240 to move in the X-axis direction, and performs laser cutting on the workpiece according to the preset cutting trajectory.

[0030] As attached Figure 2 , 3 As shown in Figure 5, a loading and unloading assembly 400 is provided on the top of the slide 120. The loading and unloading assembly 400 includes: a base 450, a turntable 460, a frame 410, and a second motor 480. The base 450 is located on the top of the housing 100, for example, by bolt fixing, welding fixing, or integral molding. A first motor 470 is provided on the top of the base 450. The turntable 460 is rotatably connected to the base 450, for example, by bearing connection. The outer wall of the turntable 460 has a toothed structure. It should be noted that the toothed structure is prior art and is not shown in the figure. The output shaft of the first motor 470 is provided with a gear with a meshing toothed structure. The gear is prior art and is not shown in the figure.

[0031] After cutting, the existing equipment requires manual removal of the finished product from the platform and placement of the wafers to be processed. Because the wafers are thin and their bottoms are suspended in the air, gripping them is difficult. If a wafer retrieval fails on the first attempt, the operating posture must be repeatedly adjusted, extending the time for each material change. Ultimately, the excessively high proportion of non-cutting time restricts overall production efficiency.

[0032] A frame 410 is positioned on top of a turntable 460, and two plates 420 are mounted on the frame 410. A second motor 480 is positioned at the bottom of the plates 420, and the output shaft of the second motor 480 is threadedly connected to a second slider 440. The output shaft is connected to a bearing in the plate 420, and the second slider 440 is slidably connected to the plate 420. A groove is provided on the plate 420 to accommodate the second slider 440. A support plate 430 is mounted on the second slider 440. A groove 422 is provided on the outer side of the plate 420 near the support plate 430, and the groove 422 is used to limit the position of the workpiece. The rotation of the turntable 460 is responsible for the workpiece's position switching, allowing it to switch between the processing position and the window position; while the vertical movement of the support plate 430 enables precise positioning and transfer of the workpiece on the clamping assembly.

[0033] Specifically, after the workpiece is cut, the rotation of the turntable 460 moves the support plate 430 below the workpiece. Then, motor 480 starts, driving slider 440 and support plate 430 to rise vertically, ensuring close contact between the support plate 430 and the bottom of the workpiece, providing stable and reliable support. At this point, the clamping assembly 300 releases the workpiece's restraints, and the support plate 430, holding the workpiece, accurately reaches the window position as the turntable 460 rotates. Operators can easily and quickly remove the finished product without directly touching the thin, bottom-suspended disc. Furthermore, before rotation, users can place the disc to be processed onto the support plate 430 at the window position. This significantly improves overall production efficiency.

[0034] As attached Figure 5 As shown, the frame 410 includes a support frame and a crossbar. The support frame is fixed to the top of the base 450; the crossbar is rotatably connected to the support frame, and support blocks are connected to both ends of the crossbar, with the support blocks fixedly connected to the plate 420. The entire frame 410 operates on the principle of leverage, relying on the balance of the fulcrum, lever arm, and force. When the weight at both ends and the lever arm length satisfy the balance condition, the crossbar remains horizontal; if the weight or lever arm at one end changes, the balance is broken, causing it to swing up and down. It should be noted that the specific balance condition is: effort × effort arm = resistance × resistance arm.

[0035] Specifically, when unloading the cut workpiece, the workpiece to be processed is placed on the support plate 430 at one end of the crossbar near the window position. Utilizing the lever principle, this causes the support plate 430 at the other end of the crossbar to rise. The clamping assembly 300 releases the workpiece from its restraints. Supported by the support plate 430, the processed workpiece reaches the window position as the turntable 460 rotates, allowing the operator to easily remove the finished product. By utilizing the lever principle, direct manual contact with the workpiece is eliminated, improving production efficiency and avoiding the difficulty of gripping thin workpieces with their bottoms suspended in the air.

[0036] As attached Figure 2-7As shown, the clamping assembly 300 is provided with a transmission assembly 500. The plate 420 continues to rise and is connected to the transmission assembly 500. The transmission assembly 500 converts the rising force into torque, thereby controlling the clamping assembly 300 to release the workpiece.

[0037] Specifically, the workpiece to be processed is placed on the support plate 430 at one end of the crossbar near the window. Using the lever principle, this causes the support plate 430 at the other end of the crossbar to rise. At this time, the plate 420 presses against the transmission component 500, which in turn drives the clamping component 300 to work. The clamping component 300 releases its grip on the workpiece. The processed workpiece, supported by the support plate 430, reaches the window position as the turntable 460 rotates, allowing the operator to easily remove the finished product. By using mechanical linkage to link the rising action with the clamping and releasing action, an automated operation process is achieved, reducing manual intervention, improving production efficiency, and also reducing the risk of human error.

[0038] As attached Figure 2-7 As shown, the transmission assembly 500 includes a transmission box 510 and a rack 560. The transmission box 510 is fixed to the inner side wall of the frame 310. The outer side wall of the screw 340 is fitted with a rod 330, and a gear 580 is fixed to the outer side wall of the rod 330. The rack 560 is slidably connected to the transmission box 510 and passes through the transmission box 510. A spring-loaded component is provided on the rack 560. The bottom end of the rack 560 is fixed with a rod 570, and the rack 560 is meshed with the gear 580.

[0039] Specifically, when the plate 420 rises and presses against the second rod 570, the rack 560 slides upward within the transmission box 510. Since the rack 560 is meshed with the gear 580, the rise of the rack 560 drives the gear 580 to rotate, which in turn drives the first rod 330 to rotate within the frame 310. This causes the limiting block 320 to move away from the workpiece, thereby releasing the clamping force on the workpiece. The springback assembly ensures that the rack 560 returns to its initial position when no external force is applied, ready for the next operation. A groove 421 for engaging the second rod 570 is provided on the top of the plate 420.

[0040] Specifically, the springback assembly includes a spring 550 and a retaining plate 530. The spring 550 is sleeved on the outer wall of the rack 560, and rings 540 are fixed to both ends of the spring 550. The retaining plate 530 is rotatably connected to the rings 540. A second screw 520 is fixed to the top of the rack 560, and the second screw 520 is threadedly connected to the retaining plate 530. By rotating the retaining plate 530, it can move on the second screw 520, thereby stretching or compressing the spring 550 and adjusting the initial elastic force of the spring 550 to accommodate workpieces of various sizes, ensuring that the transmission assembly 500 is both stable and reliable when releasing the clamp. The thread structure of the second screw 520 is not shown in the attached drawing, and the tooth structure of the rack 560 and the gear 580 is not shown.

[0041] As attached Figure 6 As shown, a protrusion 341 is fixed to the outer wall of the screw 340, and a groove for engaging the protrusion 341 is provided on the rod body 330. By pressing the rod body 330, the gear 580 is separated from the rack 560. In special operating scenarios where maintaining the workpiece clamping state is required, accidental release of clamping due to the linkage of the transmission component 500 can be avoided, enhancing the operational flexibility of the device and its adaptability to different working conditions. At the same time, when it is necessary to restore the normal function of the transmission component 500, simply pull out the rod body 330 to re-engage the gear 580 and rack 560.

[0042] As attached Figure 7 and 8 As shown, two liquid inlet pipes 610 are provided at the bottom of the plate 420. The liquid inlet pipes 610 are connected to the support plate 430. The support plate 430 has a cavity. The two support plates 430 are connected by a connecting pipe 620, which is fixedly connected to the slider 440. An air pipe 640 is fixed to the bottom of the support plate 430 and passes through the support plate 430. An adsorption port 630 is provided at the top of the support plate 430 and is connected to the air pipe 640.

[0043] Specifically, when workpieces need to be adsorbed and fixed, the relevant gas source equipment (not shown in the attached diagram, as it is existing technology and will not be described further) is activated. Gas flows through the gas pipe 640, generating adsorption force at the adsorption port 630, firmly adsorbing the workpiece placed on the support plate 430, ensuring the stability of the workpiece during transfer. Moreover, when removing the workpiece, simply turning off the gas source easily releases the adsorption, making it convenient and quick. Additionally, the liquid inlet pipe 610 provides a channel for the subsequent delivery of cooling liquid. After laser cutting, coolant is delivered to the cavity of the support plate 430 through the liquid inlet pipe 610. The coolant, via the connecting pipe 620, can simultaneously cool the workpieces on both support plates 430, effectively preventing workpiece deformation due to high temperatures and ensuring the processing quality of the workpieces. Furthermore, the injection of coolant ensures that the workpieces to be processed and the processed workpieces on the frame are in a balanced state. Utilizing the lever principle, the two ends of the frame are kept balanced, preventing tilting of the frame due to differences in workpiece weight, ensuring the stability and reliability of the entire loading and unloading process. It should be noted that the circulating pump and cooling equipment of the cooling cycle are not shown in the attached drawings, as they are existing technologies and will not be described in detail here.

[0044] In this embodiment, a stepper motor can be installed on the frame 310, and a trigger switch is installed on one side of the platform 130 near the plate 420. When one end of the frame 410 is tilted up, the trigger switch on the plate 420 is activated, and the stepper motor directly drives the screw 340 to control the position of the limit block 320. Neither the stepper motor nor the switch is shown in the attached drawings.

[0045] As attached Figure 9 As shown, the support blocks on the frame 410 are directly connected to the crossbar via friction, while the support blocks are connected to the turntable via vertical rods. When the weight of one support block increases, the support block rubs against the crossbar, causing the other end of the crossbar to lift and pull the support block on the other side. This method ensures that the plate 420 on the support block remains vertical. Whether placing the workpiece to be processed or unloading the processed workpiece, the support plate 430 on the plate 420 can accurately contact the workpiece, ensuring the stability of the workpiece during transfer.

[0046] Working principle: In the initial state, the diamond workpiece to be cut is placed on the inner wall of the frame 310 of the clamping assembly 300. By rotating the screw 340, the limiting block 320 slides on the inner wall of the frame 310. The position of the limiting block 320 can be flexibly adjusted according to the size of the workpiece to achieve effective clamping of the workpiece. The special inclined surface of the inner wall of the frame 310 and the arc-shaped surface design of the limiting block 320 increase the contact area with the workpiece, making the clamping more stable.

[0047] After the device is started, the displacement component 200 begins to operate. The cylinder 230 moves the laser cutting head 240 to a suitable position in the Y-axis direction, while the gantry slide 210 moves the laser cutting head 240 in the X-axis direction. The gantry slide 210, with its high-rigidity mechanical structure, precision servo drive system, and closed-loop feedback control, ensures that the laser cutting head 240 performs laser cutting on the workpiece according to the preset cutting trajectory.

[0048] After laser cutting, to prevent workpiece deformation due to high temperature and thus affecting processing quality, coolant is supplied to the cavity of the support plate 430 through the liquid inlet pipe 610. The coolant simultaneously cools the workpieces on both support plates 430 via the connecting pipe 620. At the same time, the injected coolant ensures that the workpieces to be processed and processed on the frame 410 are in a balanced state. The lever principle is used to maintain balance at both ends of the frame, ensuring a smooth and reliable loading and unloading process.

[0049] After the workpiece is cut, it enters the workpiece unloading stage. By controlling the rotation of the turntable 460, the support plate 430 is moved to below the workpiece. Then, the second motor 480 starts, driving the second slider 440 and the support plate 430 to rise vertically, so that the support plate 430 makes close contact with the bottom of the workpiece, providing stable support for the workpiece. At this time, if the clamping is released by mechanical linkage, the plate 420 rises and presses the second rod 570. The rack 560 slides upward in the transmission box 510. Since the rack 560 is meshed with the gear 580, the upward transmission gear 580 of the rack 560 rotates, which in turn drives the first rod 330 to rotate in the frame 310, causing the limit block 320 to move away from the workpiece, releasing the clamping of the workpiece. If other methods are used, such as setting a stepper motor on the frame 310 and setting a trigger switch on one side of the platform 130 near the plate 420, after one end of the frame 410 is tilted up, the stepper motor directly drives the screw 340 to control the position of the limit block 320.

[0050] After being released from the clamp, the processed workpiece, supported by the support plate 430, accurately reaches the window position as the turntable 460 rotates. Operators can easily and quickly remove the finished product without directly touching the thin, bottom-suspended disc. Furthermore, before rotation, the user can place the disc to be processed onto the support plate 430 at the window position. Through leverage, the other end of the crossbar, the support plate 430, rises, positioning the workpiece appropriately for the next cutting operation. The entire device, through the coordinated operation of its components, achieves efficient and precise cutting of diamond workpieces and convenient workpiece loading and unloading, improving production efficiency and reducing the risks associated with manual operation.

[0051] When loading the workpiece using the lever principle of the frame 410, the plate 420 applies pressure to the transmission component 500, controlling the clamping component 300 to open. At this time, the workpiece to be processed is located between the frame 310 and the limiting block 320. The control motor 480 then operates, driving the support plate 430 to rise to a certain height, thus raising the workpiece to be processed to a certain height. After the workpiece to be processed is placed at the other end of the frame 410, the plate 420 near the clamping component 300 separates from the transmission component 500 due to the lever principle. At this time, the transmission component 500 reverses the control of the limiting block 320, limiting the workpiece to be processed. This limiting method greatly improves the accuracy of workpiece placement and reduces errors caused by improper manual placement.
