The cutting position of the saw mechanism 2 is adjusted by controlling the lifting and lowering of the lifting mechanism 20 and the horizontal position of the translation assembly 30 to achieve fine cutting of the optical glass.

[0025] In this embodiment, a transverse base plate 35 is provided on one side of the translation assembly 30, and the transverse base plate 35 is fixedly connected to the outer frame 40 on the side of the saw mechanism 2 by screws; the slider base plate 31 on one side of the translation assembly 30 and the longitudinal base 28 on the side of the lifting mechanism 20 are fastened by screws, and the movable platform 3 is arranged vertically to the saw mechanism 2, ensuring that the saw blade 42 always maintains a vertical cutting state with the movable platform 3 during movement. The movable platform 3 includes a workbench 11 with an opening, and the opening on the workbench can completely accommodate the saw blade 42. The workbench 11 is used to support the surface of the optical glass.

[0026] The usage of this utility model is as follows:

[0027] 1. When in use, first place the optical glass plate to be cut on the workbench 11, and control the translation assembly 30 to move the saw blade 42 horizontally to the specified position through a predetermined program set by the control device 4;

[0028] 2. Control the lifting mechanism 20 through the control device 4 so that the translation assembly 30 drives the saw mechanism 2 to move downward, so that the saw blade 42 of the saw mechanism 2 is in close contact with the surface of the optical glass;

[0029] 3. Start the switch on the control device 4, the saw blade motor 41 starts to drive the saw blade 42 to rotate, and then pushes the movable platform 3 to drive the optical glass forward, and the optical glass cutting operation can be carried out normally;

[0030] 4. After the cutting is completed, turn off the switch of the saw blade motor 41 on the control device 4, and then reset the lifting mechanism 20 and the translation assembly 30.

[0031] Further, such as Figure 1-3As shown, the movable platform 3 also includes two linear guide rails 12 fixed on the base 1 and arranged in parallel, a slide 13 fixed to the bottom surface of the workbench 11, and a gas spring 14 fixedly connected to the workbench 11 for buffering. In this embodiment, the two linear guide rails 12 are parallel to the direction of the saw blade 42 and are used to control the workbench 11 to move forward in the direction of the saw blade 42; the movable end of the gas spring 14 is fixed to the bottom surface of the workbench 11 with bolts, and the fixed end is fixed to the base 1 with bolts, which is used to buffer the horizontal movement speed of the workbench 11, and ultimately can control the horizontal feed speed of the saw blade 42.

[0032] Further, such as Figure 4 As shown, the lifting mechanism 20 includes a Z-direction bracket 21 fixed above the base 1. In this embodiment, the bracket 21 is in the shape of a gate and includes four fixed rods arranged horizontally and vertically, of which two vertical fixed rods are fixedly connected to the base 1 by welding; four symmetrically arranged support seats 22 are fixed to the two horizontal fixed rods by threaded connections, which are used to support the guide shaft 25; two Z-direction slide rails 23 are arranged in parallel and fixed to the two vertical fixed rods of the Z-direction bracket 21 by threaded connections; the two end heads of the two guide shafts 25 are fixed between the four support seats 22 by adjustable fixing clamps, which are used to guide the vertical movement of the lifting mechanism 20.

[0033] Further, such as Figure 1-5 As shown, a Z-direction screw 24 and a Z-direction slide 26 slidably connected to the Z-direction screw 24 are provided between the two guide shafts 25. A threaded through hole is provided at the center of the slide 26, which is adapted to the Z-direction screw 24, and the Z-direction screw 24 passes through the threaded through hole and is connected to the Z-direction slide 26 to form a screw transmission structure; a Z-direction motor 27 for driving the lifting mechanism 20 to move is also threadedly fixedly connected to the top of the Z-direction screw 24; the lower end of the Z-direction motor 27 is practically threadedly fixedly connected to the top of the Z-direction screw 24. In this way, when the lifting mechanism 20 needs to slide, the Z-direction motor 27 is started, the Z-direction motor 27 drives the screw transmission structure to rotate, and the Z-direction screw 24 rotates to drive the Z-direction slide 26 to slide up and down along the two guide shafts 25; thereby realizing the vertical movement of the lifting mechanism 20 along the slide rail 23;

[0034] Furthermore, the top of the slider on one side of the Z-direction slide rail 23 is fixedly connected to a rectangular longitudinal base 28 by threads. The longitudinal base 28 is used to fix the translation assembly 30. The side of the Z-direction slide 26 is fixedly connected to the longitudinal base 28 by threads. The longitudinal base 28 is driven to move by the Z-direction motor 27, thereby driving the translation assembly 30 as a whole to move in the vertical direction.

[0035] Further, such as Figure 1-5As shown, the translation assembly 30 includes a slider base plate 31 which is fastened to the longitudinal base plate on the side of the lifting mechanism 20 by threads; two Y-axis slide rails 32 are parallel to each other and are fixed to the bottom surface of the slider base plate 31 by threads; a Y-axis screw 33 is rotatably connected to the slider base plate 31, and a threaded through hole is provided at the center position of the slider base plate 31. The Y-axis screw 33 passes through the threaded through hole and is connected to the slider base plate 31 to form a screw transmission structure; one end of the Y-axis screw 33 is connected to the output end of the Y-axis motor 34 by a coupling to drive the translation assembly 30 to reciprocate in the horizontal direction; the translation assembly 30 also includes a transverse base plate 35 for fixing the saw mechanism 2, and the base of the Y-axis motor 34 is fixed to the transverse base plate 35 by threads.

[0036] Furthermore, the saw mechanism 2 includes an outer frame 40 fixedly connected to the translation assembly 30. In this embodiment, the outer frame 40 is formed of four flat panels forming a square structure, which is used to accommodate a saw blade motor 41. The base of the saw blade motor 41 is bolted to the top of the bottom plate of the outer frame 40. A protective cover 43 is fixed to a side plate of the outer frame 40 via a threaded connection, at least partially covering the saw blade, for protecting the saw blade 42 located therein. The output end of the saw blade motor 41 is fixedly connected to the main shaft of the saw blade 42 via a coupling 44, for driving the saw blade 42 to rotate. The main shaft of the saw blade 42 is fixed to both sides of the protective cover 43 via bearings. The protective cover 43 is typically made of a metal material such as aluminum or cast iron to improve rigidity.

[0037] Furthermore, the optical glass cutting equipment also includes a control device 4 for controlling the movement of the saw mechanism 2. The control device 4 is fixed above the base 1. In this embodiment, the control device 4 is a single-chip microcomputer or a PLC. The control device 4 is electrically connected to the saw mechanism 2, the lifting mechanism 20 and the translation assembly 30. When the optical glass needs to be cut, the start and stop of the saw mechanism 2, the vertical lifting of the lifting mechanism 20 and the horizontal movement of the translation assembly 30 can be controlled by operating the program on the control device 4 to achieve precise cutting of the optical glass.
