Description

Technical Field

[0001] This utility model relates to processing equipment for lithium tantalate single crystal rods, specifically to a lithium tantalate single crystal rod cutting mechanism. Background Technology

[0002] After lithium tantalate single crystal rods are processed, they need to be cut to meet different reprocessing requirements. Existing lithium tantalate single crystal rod cutting equipment generally involves setting up a cutting machine on a processing platform. During cutting, the lithium tantalate single crystal rod is placed on the processing platform, and then the cutting machine cuts the lithium tantalate single crystal rod into circular pieces of a preset length. For example, Chinese utility model patent application number CN202323314435.7 discloses a single crystal rod cutting device, including a support column, a table, the table being fixedly set above the support column; a moving mechanism is set below the table; and a first sliding mechanism is fixedly set above the moving mechanism to reduce friction between the clamping mechanism and the table. This invention, by starting motor one, drives bolt one above the drive shaft of motor one to rotate, thus causing threaded barrel one and threaded barrel two to move towards each other. Compared with traditional devices, this device can move the first sliding mechanism by starting the moving mechanism, which in turn moves the clamping mechanism. By moving the clamping mechanism, the clamping length can be changed, avoiding the problem of unstable clamping of the single crystal rod due to insufficient clamping length, which could lead to damage to the single crystal rod. At the same time, it can also reduce the movement of the rod and improve work efficiency. Although the cutting equipment disclosed in the patent does have some advantages, the cutting blade in this cutting equipment is fixedly mounted on the fixed frame, which makes it impossible to adjust the position of the cutting blade. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing a lithium tantalate single crystal rod cutting mechanism.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a lithium tantalate single crystal rod cutting mechanism, comprising:

[0005] Cutting blade;

[0006] A power mechanism is provided to drive the cutting blade to rotate. The power mechanism includes a drive motor, a first pulley, a second pulley, a transmission belt, and a rotating rod. The first pulley is mounted on the drive motor, causing the drive motor to drive the first pulley to rotate. The second pulley is fixedly mounted on one end of the rotating rod. The transmission belt connects the first pulley and the second pulley, so that when the first pulley rotates, it drives the second pulley to rotate, and the second pulley drives the rotating rod to rotate. The cutting blade is fixedly mounted on the other end of the rotating rod, so that the drive motor drives the cutting blade to rotate.

[0007] The first position adjustment mechanism includes a connecting sleeve and a first hydraulic cylinder. The connecting sleeve has a rotating through hole that extends through the connecting sleeve along its axial direction. A rotating rod is inserted into and passes through the rotating through hole, and the rotating rod is rotatable within the rotating through hole. The first hydraulic cylinder and the connecting sleeve are fixedly connected, such that the first hydraulic cylinder drives the connecting sleeve to move, and the connecting sleeve drives the rotating rod to move, thereby driving the cutting blade to move.

[0008] In some embodiments of this application, a single crystal rod moving mechanism is also included. The single crystal rod moving mechanism includes a preset number of first rotating wheels, a preset number of second rotating wheels, and a preset number of pressing rotating wheels. The first rotating wheels and the second rotating wheels are located at the same height and are aligned, and there is a preset distance between the first rotating wheels and the second rotating wheels. The pressing rotating wheels are located above the first rotating wheels, and the lithium tantalate single crystal rod is placed on the first rotating wheels and the second rotating wheels. The pressing rotating wheels press the lithium tantalate single crystal rod.

[0009] In some embodiments of this application, the single crystal rod moving mechanism further includes a first mounting plate, a second mounting plate, and a third mounting plate. The first rotating wheel is fixedly mounted on the first mounting plate and is rotatable relative to the first mounting plate. The pressing rotating wheel is fixedly mounted on the second mounting plate and is rotatable relative to the second mounting plate. The second rotating wheel is fixedly mounted on the third mounting plate and is rotatable relative to the third mounting plate.

[0010] In some embodiments of this application, the first position adjustment mechanism further includes a connecting plate, which is fixedly connected to the connecting sleeve on one hand, and fixedly connected to the first hydraulic cylinder on the other hand, so that the first hydraulic cylinder and the connecting sleeve are fixedly connected together.

[0011] In some embodiments of this application, the first position adjustment mechanism further includes a support rod, which is fixedly installed together with the first hydraulic cylinder, so that the support rod is used to support the first hydraulic cylinder.

[0012] In some embodiments of this application, a second position adjustment mechanism is also included. The second position adjustment mechanism includes a second hydraulic cylinder, a connecting buckle, and a support plate. The drive motor is fixedly mounted on the support plate 4, and the support rod of the first position adjustment mechanism is fixedly connected to the support plate. The connecting buckle is fixedly engaged with the support platform on one hand, and fixedly connected to the second hydraulic cylinder on the other hand, so that the second hydraulic cylinder drives the support plate to move, thereby driving the cutting blade to move.

[0013] In some embodiments of this application, a support platform is also included, and the second position adjustment mechanism further includes a sliding rail and a slider. The sliding rail is fixedly installed on the support platform, and the slider is fixedly installed on the support plate and slidably connected to the sliding rail, so that when the second hydraulic cylinder pushes the support plate, the support plate moves relative to the support platform.

[0016] The beneficial effects of this application are as follows: The lithium tantalate single crystal rod cutting mechanism provided by this application has the advantages of simple structure and easy assembly and disassembly.

Through the cooperation of the first and second position adjustment mechanisms, the cutting blade is moved to a preset position. Thus, after the lithium tantalate single crystal rod is cut, a large number of lithium tantalate single crystal wafers accumulate on the support platform. At this time, moving the cutting blade to the preset position facilitates the arrangement and movement of these lithium tantalate single crystal wafers. Attached Figure Description

[0023] Please refer to Figure 1-3 This application provides a lithium tantalate single crystal rod cutting mechanism (hereinafter referred to as "the cutting mechanism"). The cutting mechanism can adjust the position of the cutting blade. After the cutting mechanism completes the cutting of the lithium tantalate single crystal rod, the position of the cutting blade is adjusted so that the cutting blade is far away from the lithium tantalate single crystal wafer that has been cut, thereby making it easier to collect the lithium tantalate single crystal wafer.

[0024] The cutting mechanism includes:

[0025] Cutting blade 1;

[0026] The power mechanism 2 drives the cutting blade 1 to rotate. The power mechanism 2 includes a drive motor 21, a first pulley 22, a second pulley 23, a transmission belt 24, and a rotating rod 25. The first pulley 22 is mounted on the drive motor 21, causing the drive motor 21 to drive the first pulley 22 to rotate. The second pulley 23 is fixedly mounted on one end of the rotating rod 25. The transmission belt 24 connects the first pulley 22 and the second pulley 23 together, so that when the first pulley 22 rotates, it drives the second pulley 23 to rotate, and the second pulley 23 drives the rotating rod 25 to rotate. The cutting blade 1 is fixedly mounted on the other end of the rotating rod 25, so that the drive motor 21 drives the cutting blade 1 to rotate.

[0027] The first position adjustment mechanism 3 includes a connecting sleeve 35 and a first hydraulic cylinder 32. The connecting sleeve 35 has a rotating through hole 350 that extends through the connecting sleeve 35 along its axial direction. A rotating rod 25 is inserted into and passes through the rotating through hole 350 and is rotatable within the rotating through hole 350. The first hydraulic cylinder 32 and the connecting sleeve 35 are fixedly connected, such that the first hydraulic cylinder 32 drives the connecting sleeve 35 to move, and the connecting sleeve 35 drives the rotating rod 25 to move, thereby driving the cutting blade 1 to move. In this application, when moving the cutting blade 1, the drive motor 21 is turned off first, and the rotating rod 25 will no longer rotate. Then, the first hydraulic cylinder 32 is turned on to push the connecting sleeve 35 to the preset position. At this time, the cutting blade 1 is also moved to the preset position. After the lithium tantalate single crystal wafer on the platform is completely transferred, the first hydraulic cylinder 32 is started to pull the connecting sleeve 35 to the initial position. Then, the drive motor 21 is turned on, and the drive motor 21 drives the cutting blade 1 to rotate.

[0036] The lithium tantalate single crystal rod cutting mechanism provided in this application has the advantages of simple structure and easy assembly and disassembly. Furthermore, given the inclusion of a first position adjustment mechanism and a second position adjustment mechanism, the first position adjustment mechanism can adjust the position of the cutting blade in the vertical direction, i.e., the cutting blade can move upwards or downwards; the second position adjustment mechanism can adjust the position of the cutting blade in the horizontal direction.
