Description

Technical Field

[0001] This utility model relates to the field of quartz crucible crushing, and in particular to a quartz crucible crushing device. Background Technology

[0002] In the single crystal pulling process, the thermal field is the core component for single crystal growth. The correct use of the thermal field can effectively improve the crystal formation effect of the single crystal furnace. Because quartz crucibles may experience crystallization, local bulging, bending, and other deformation problems during use, in order to prevent leakage after prolonged crystal pulling, the quartz crucible inside the carbon-carbon crucible usually needs to be removed and replaced after one batch of single crystals is pulled.

[0003] During dismantling, the quartz crucible cannot be directly removed because it is in close contact with the carbon-carbon crucible. Typically, a hammer is used to manually break the quartz crucible. However, this method results in inconsistent striking force, easily damaging the carbon-carbon crucible. Furthermore, manual labor is physically demanding, inefficient, and poses safety hazards.

[0004] To reduce labor intensity, a type of crushing equipment has emerged. However, due to the uneven surface of the quartz crucible, the existing crushing equipment cannot cut according to the shape trajectory of the quartz crucible. That is, the cutting trajectory is the same from beginning to end. Either it cannot cut completely and the quartz crucible cannot be separated from the carbon crucible, or the cutting range is too large and damages the carbon crucible. It has poor adaptability, low cutting accuracy, and poor crushing effect. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a quartz crucible crushing device with high cutting accuracy and good crushing effect.

[0006] To address the aforementioned technical problems, this utility model provides a quartz crucible crushing device, comprising a frame and a crushing apparatus mounted on the frame. The crushing apparatus includes a cutting unit and a movement control unit, which are connected. The movement control unit controls the positional movement of the cutting unit. The cutting unit includes a drive mechanism, an angle grinder, and a trajectory sensing mechanism. The drive mechanism is connected to both the angle grinder and the trajectory sensing mechanism. The trajectory sensing mechanism detects the surface trajectory of the quartz crucible. The drive mechanism uses the detection of the trajectory sensing mechanism to enable the angle grinder to cut along the trajectory on the surface of the quartz crucible.

[0007] As an improvement to the above solution, the trajectory sensing mechanism includes a roller, an elastic element, and a displacement sensor. The roller and the elastic element are connected so that the roller abuts against the surface of the quartz crucible. The displacement sensor is used to detect changes in the displacement of the roller.

[0008] As an improvement to the above solution, the elastic element is a cylinder.

[0009] As an improvement to the above solution, the cutting unit further includes a movable base, on which the driving mechanism, angle grinder, and trajectory sensing mechanism are all mounted; The mobile control unit is connected to the mobile base to drive the cutting unit to move.

[0010] As an improvement to the above solution, the motion control unit includes a translation motor and a translation guide rail. The translation motor is connected to the moving seat to drive the moving seat to move along the translation guide rail.

[0011] As an improvement to the above solution, the drive mechanism further includes a drive motor and a transmission assembly, wherein the drive motor is connected to the angle grinder through the transmission assembly; The transmission assembly includes a ball screw, a screw nut, and a base, and the drive motor, ball screw, screw nut, base, and angle grinder are connected in sequence.

[0012] As an improvement to the above solution, the crushing device further includes a clamping mechanism for fixing the workpiece, the clamping mechanism being mounted on the frame; The clamping mechanism includes a clamp base and clamps, with the clamps mounted on the clamp base.

[0013] As an improvement to the above solution, the quartz crucible crushing equipment also includes a protective mechanism for isolating the crushing device from the outside world, the protective mechanism being mounted on the frame; The protective mechanism includes a protective cover that can be fitted over the crushing device.

[0014] As an improvement to the above solution, the protective mechanism further includes a slider and a slide rail, the slider and the slide rail being slidably connected, and the slider and the protective cover being fixedly connected; The protective cover is equipped with a dust removal port.

[0015] As an improvement to the above solution, the quartz crucible crushing equipment also includes a control device, which is mounted on the frame; The motion control unit, drive mechanism, angle grinder, and trajectory sensing mechanism are electrically connected to the control device.

[0016] The following are the beneficial effects of implementing this utility model: This utility model's quartz crucible crushing equipment uses a trajectory sensing mechanism to detect the surface trajectory of the quartz crucible, allowing the angle grinder to cut according to this trajectory. This results in strong adaptability, high cutting precision, and excellent cutting effect. Specifically, during the movement of the cutting unit driven by the motion control unit, the trajectory sensing mechanism detects the surface trajectory of the quartz crucible. The drive mechanism then drives the angle grinder to rise and fall based on this detected trajectory, allowing it to move along the surface trajectory of the quartz crucible and cut along its shape. This ensures complete cutting of the quartz crucible without damaging it, demonstrating strong adaptability, high cutting precision, and excellent cutting effect. Attached Figure Description

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the following will describe this utility model in further detail with reference to the accompanying drawings. It is hereby declared that the terms "up," "down," "left," "right," "front," "back," "inner," and "outer," etc., appearing or about to appear in this document, are based solely on the accompanying drawings and are not intended to specifically limit this utility model.

[0019] See Figure 1-4 This utility model discloses a quartz crucible crushing device, including a frame 1 and a crushing device 200 installed on the frame 1. The crushing device 200 includes a cutting unit and a movement control unit, which are connected. The movement control unit is used to control the position movement of the cutting unit. The cutting unit includes a driving mechanism, an angle grinder 3, and a trajectory sensing mechanism. The driving mechanism is connected to the angle grinder 3 and the trajectory sensing mechanism respectively. The trajectory sensing mechanism is used to detect the surface trajectory of the quartz crucible.

[0020] The drive mechanism uses the detection of the trajectory sensing mechanism to make the angle grinder 3 cut along the trajectory on the surface of the quartz crucible.

[0021] This utility model's quartz crucible crushing equipment uses a trajectory sensing mechanism to detect the surface trajectory of the quartz crucible, allowing the angle grinder to cut according to this trajectory. This results in strong adaptability, high cutting precision, and excellent cutting effect. Specifically, during the movement of the cutting unit driven by the motion control unit, the trajectory sensing mechanism detects the surface trajectory of the quartz crucible. The drive mechanism then drives the angle grinder to rise and fall based on this detected trajectory, allowing it to move along the surface trajectory of the quartz crucible and cut along its shape. This ensures complete cutting of the quartz crucible without damaging it, demonstrating strong adaptability, high cutting precision, and excellent cutting effect.

[0022] It should be noted that, as Figure 2 As shown, the quartz crucible crushing equipment also includes a control device 8, which is mounted on the frame 1; the motion control unit, drive mechanism, angle grinder 3 and trajectory sensing mechanism are electrically connected to the control device 8 respectively.

[0023] Specifically, such as Figure 4 As shown, the trajectory sensing mechanism includes a roller 41, an elastic element 42, and a displacement sensor 43. The roller 41 and the elastic element 42 are connected so that the roller 41 abuts against the surface of the quartz crucible. The displacement sensor 43 is used to detect the displacement change of the roller 41. The elastic element 42 is preferably a cylinder or a spring. The elastic element provides elastic force to the roller, keeping the roller in contact with the surface of the quartz crucible. Simultaneously, with the cooperation of the elastic element, the roller will change its position and distance from the displacement sensor according to the uneven trajectory of the quartz crucible surface. The displacement sensor converts this change into a signal and transmits it to the control device. The control device controls the drive mechanism according to the signal, causing the angle grinder and the roller to move synchronously.

[0024] In some embodiments, such as Figure 3 As shown, the cutting unit also includes a movable base 9, on which the driving mechanism, angle grinder 3 and trajectory sensing mechanism are all mounted; the moving control unit is connected to the movable base 9 to drive the cutting unit to move.

[0025] The motion control unit drives the motion base to translate, thereby driving the drive mechanism, angle grinder, and trajectory sensing mechanism to translate together. In other words, it drives the drive mechanism, angle grinder, and trajectory sensing mechanism to move synchronously along the axial direction of the quartz crucible, ensuring that the angle grinder can move synchronously with the roller along the trajectory on the surface of the quartz crucible under the drive of the drive mechanism.

[0026] In some embodiments, such as Figure 3As shown, the motion control unit includes a translation motor 51 and a translation guide rail 52. The translation motor 51 is connected to a moving base 9 to drive the moving base 9 to move along the translation guide rail 52. The moving base 9 and the translation guide rail 52 are slidably connected. A balancing motor drives the moving base to move, causing it to move under the guidance of the translation guide rail, ensuring that the cutting unit moves back and forth in a predetermined direction, thereby ensuring the accuracy of the trajectory sensing mechanism in detecting the surface trajectory of the quartz crucible.

[0027] In some embodiments, the driving mechanism further includes a drive motor 2 and a transmission assembly. The drive motor 2 is connected to the angle grinder 3 via the transmission assembly. The transmission assembly includes a ball screw 21, a screw nut (not shown), and a base 31. The drive motor 2, ball screw 21, screw nut, base 31, and angle grinder 3 are connected in sequence. The ball screw 21 and screw nut are connected, the base 31 is mounted on the screw nut, and the angle grinder 3 is mounted on the base 31.

[0028] The drive motor is connected to the ball screw through a coupling, driving the ball screw to rotate. This causes the screw nut to move back and forth along the ball screw, which in turn drives the machine base, i.e., the angle grinder, to move. This allows the angle grinder and the roller to move synchronously along the surface trajectory of the quartz crucible, enabling the angle grinder to cut along the surface trajectory of the quartz crucible.

[0029] In some embodiments, such as Figure 2 As shown, the crushing device 200 also includes a clamping mechanism for fixing the workpiece 100, which is mounted on the frame 1. The clamping mechanism includes a clamping base 61 and a clamp 62, with the clamp 62 mounted on the clamping base 61. The clamp is fixed to the frame via the clamping base, and the clamp clamps the workpiece, thereby fixing the workpiece on the frame and ensuring the reliability and stability of the cutting.

[0030] In some embodiments, such as Figure 1 As shown, the quartz crucible crushing equipment also includes a protective mechanism for isolating the crushing device 200 from the outside world. The protective mechanism is installed on the frame 1. The protective mechanism includes a protective cover 71, which can be fitted over the crushing device 200.

[0031] The protective cover is designed to prevent dust generated during the cutting process from flying outwards and causing environmental pollution, and also to prevent foreign objects from coming into contact with the cutting process and affecting it.

[0032] In some embodiments, the protective mechanism further includes a slider (not shown) and a slide rail 72, the slider and the slide rail 72 being slidably connected, and the slider and the protective cover 71 being fixedly connected. The slide rail 72 is mounted on the frame 1, and the protective cover can slide on the frame via the slider and the slide rail, saving manpower. Before cutting, the workpiece is first fixed on the clamp by clamps, and the protective cover is pushed along the slide rail to cover the workpiece and the crushing device and seal it, before the crushing device is started for cutting.

[0033] In some embodiments, such as Figure 1 As shown, the protective cover 71 is provided with a dust removal port 73. The dust removal port is connected to the pump body to suck away the dust inside the protective cover, so as to avoid affecting the cutting effect and the health of the workers.

[0034] In summary, this utility model provides a quartz crucible crushing device with high cutting precision and good crushing effect.

[0035] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
