Description

Technical Field

[0001] This invention relates to the field of window manufacturing technology, specifically to a processing device and method for plastic optical windows with stable clamping. Background Technology

[0002] An optical window is a transparent element used in an optical system. It allows visible light or other electromagnetic radiation within a specific wavelength range to pass through while protecting the system's interior from external environmental influences. Optical windows are typically made of highly transparent materials that allow light to propagate through the optical system with minimal attenuation, scattering, or absorption. They have numerous applications in optical instruments, laser systems, optical communications, space exploration, industrial applications, and the medical field. Some common optical window materials include glass (such as borosilicate glass and quartz glass), transparent ceramics (such as alumina ceramics), resins, and plastics. During the manufacturing process, these windows need to be processed into specific sizes to meet the needs of different scenarios. Generally, when cutting optical window materials, specialized fixtures designed according to the shape are required to ensure balanced force during the cutting process and prevent breakage. The edges of the cut optical windows are sharp and can easily scratch operators, requiring specialized machines for chamfering and edge grinding. Summary of the Invention

[0003] The purpose of this invention is to provide a processing apparatus and method for plastic optical windows with stable clamping, so as to solve the problems mentioned in the background art.

[0004] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a processing device for a plastic optical window with stable clamping, comprising a support frame, a moving module, a window plate to be cut, a material conveyor, a cutting wire, and two sets of drive motors for driving the cutting wire to cut. The moving module is located on one side of the support frame, and the material conveyor is located on the side of the moving module away from the base. The support frame is provided with a base and a first drive device. The hydraulic cylinder is located below the base, and the window plate is located on the base. The base is provided with a feeding roller and an auxiliary gripper. A second drive device for driving rotation is provided on one side of the material pressure roller. A cutting frame is provided on the moving module. The cutting frame is provided with a cutting mechanism, an upper clamping group, a lower clamping group, and an edge grinding mechanism. The upper clamping group and the lower clamping group have the same structure and are arranged symmetrically above and below each other. The first drive device is a hydraulic cylinder, and the second drive device is a motor. The window plate to be cut is placed on the base. The control system drives the feeding pressure roller to rotate by controlling the motor. The feeding pressure roller pushes the window plate out of the base. The auxiliary gripper clamps hold and fix the window plate that extends out of the base.

[0005] Furthermore, the cutting frame is U-shaped and hollow inside. The cutting mechanism includes an upper synchronous rotating block and a lower synchronous rotating block, which are rotatably connected to the cutting frame. The upper and lower synchronous rotating blocks are symmetrically installed. A driven sprocket is connected to the side of the upper and lower synchronous rotating blocks that contacts the cutting frame. The driven sprocket is located inside the cutting frame.

[0006] Furthermore, the cutting mechanism includes a first motor and a rotating shaft. The rotating shaft is installed inside the cutting frame and connected to the first motor. A drive sprocket is provided on the rotating shaft at a position corresponding to the height of two driven sprockets. Each drive sprocket is connected to a driven sprocket at the same height by a chain. The moving module drives the cutting frame to move and change position. Under the action of the control system, the first motor drives the rotating shaft to rotate. The two drive sprockets on the rotating shaft rotate synchronously. The drive sprockets drive the two driven sprockets to rotate through the chain. The upper synchronous rotating block and the lower synchronous rotating block can rotate synchronously at the same time.

[0007] Furthermore, both the upper and lower synchronous rotating blocks are equipped with a slide rail and a lead screw. A first servo motor is installed inside the upper and lower synchronous rotating blocks at the position corresponding to the lead screw. Two first servo motors are connected to two lead screws respectively. Two sets of drive motors are slidably mounted on the two slide rails. Each drive motor has a threaded hole that engages with the lead screw, and the threaded hole is threadedly connected to the lead screw. The two sets of drive motors are installed vertically opposite each other. The cutting wire is installed between the two sets of drive motors. While the upper and lower synchronous rotating blocks rotate, the control system simultaneously powers on the two first servo motors. The first servo motors drive the lead screws to rotate, and the lead screws, through threaded transmission, cause the two sets of drive motors to slide along the slide rails. The rotation of the upper and lower synchronous rotating blocks causes the area covered by the slide rails to form a circular region. The first servo motors control the movement of the drive motors, allowing the cutting wire to follow any trajectory on the viewing window. Through the coordination of the rotation of the upper and lower synchronous rotating blocks and the sliding movement of the drive motors, cutting of any shape within the circular region can be achieved.

[0008] Furthermore, the upper clamping assembly includes an electric push rod and an integrated compartment. The push rod piston of the electric push rod passes through the cutting mechanism. The integrated compartment is mounted on the electric push rod. A first clamping arm and a second clamping arm are rotatably arranged inside the integrated compartment. The first clamping arm is located on the side where the upper clamping assembly and the lower clamping assembly are close to each other, and the second clamping arm is located on the side where the upper clamping assembly and the lower clamping assembly are far apart from each other. A rubber pad is connected to both ends of the first clamping arm and the second clamping arm, and the four rubber pads are located on the same plane.

[0009] Furthermore, a second servo motor is installed on the outer side of the integrated compartment. A driven bevel gear is installed at the end of both the first and second clamping arms that are close to each other. The driven bevel gear is located at the rotatable connection between the first and second clamping arms and the integrated compartment. A driving bevel gear is mounted on the second servo motor. The driving bevel gear meshes with the two driven bevel gears. Before cutting, if the viewing window to be cut is rectangular, the second servo motor drives the driving bevel gear to rotate. The driving bevel gear drives the two driven bevel gears to rotate, and the two driven bevel gears respectively drive the first and second clamping arms. The reverse motion causes the four rubber pads on the first and second clamping arms to approach the four corners of the rectangle. If the window panel to be cut is circular, the second servo motor drives the first and second clamping arms to rotate into a perpendicular state, and the four rubber pads approach the four quadrants of the circle. The electric push rod pushes the integrated chamber to move, so that the rubber pads on the upper and lower clamping groups contact the window panel and clamp it. Depending on the shape of the window panel to be cut, the clamping method between the rubber pads and the unloading area is changed so that the clamping point is close to the stress point of the cutting edge, which is more conducive to maintaining stability when the window panel is cut.

[0010] Furthermore, the edge grinding mechanism is mounted on the lower synchronous rotating block. The edge grinding mechanism includes a grinding rail and a slider. The grinding rail is located on the lower synchronous rotating block, and the slider is slidably mounted in the grinding rail. An electromagnetic spring is provided between the slider and the lower synchronous rotating block. A spline shaft is mounted on the slider. Baffles are provided at the upper and middle parts of the spline shaft. A small motor is installed inside the slider. The small motor is connected to the spline shaft. An upper chamfering wheel, a contact wheel, and a lower chamfering wheel are arranged sequentially from top to bottom between the two baffles of the spline shaft.

[0011] The upper and lower chamfering wheels are slidably installed on the spline shaft, and the edge-contacting wheel is sleeved on the spline shaft. Small springs are respectively installed between the upper and lower chamfering wheels and the two baffles. After the window is cut and the material is cut, the upper and lower clamping groups lower the window. After it is lowered to the height of the edge-grinding mechanism, the first motor continues to drive the upper and lower synchronous rotating blocks to rotate. At the same time, the electromagnetic spring is energized. Under the action of electromagnetic force, the electromagnetic spring begins to tighten. The edge-contacting wheel contacts the edge of the window, and the small motor drives the spline shaft to rotate quickly. The spline shaft causes the upper and lower chamfering wheels to rotate. The rotation of the grinding rail causes the edge-contacting wheel to roll along the contour of the window under the action of the component force. The upper and lower chamfering wheels chamfer and grind the edge of the window. After grinding, the hydraulic cylinder pushes the window onto the material conveyor, completing the cutting of one window.

[0012] Processing method for a processing apparatus for a plastic optical window with stable clamping:

[0013] S1: The viewing window is set on the base, the feeding roller pushes the viewing window to extend out of the base, and the auxiliary gripper clamps the part of the viewing window that extends out of the base for stability.

[0014] S2: The moving module drives the cutting frame to move, and the upper clamping group and the lower clamping group adjust the state of the first clamping arm and the second clamping arm according to the size of the cutting shape in the window and clamp the cutting part.

[0015] S3: The cutting mechanism uses a cutting wire to cut the viewing window panel;

[0016] S4: After the cutting is completed, the upper clamping group and the lower clamping group drive the unloading part to descend, and the hydraulic cylinder pushes the viewing window onto the material conveyor.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] 1. While the upper and lower synchronous rotating blocks rotate, the first servo motor drives two sets of drive motors to slide along the slide rail. The rotation of the upper and lower synchronous rotating blocks causes the area covered by the slide rail to form a circular area. The first servo motor controls the movement of the drive motors so that the cutting wire can walk on any trajectory on the viewing window. Through the coordination of the rotation of the upper and lower synchronous rotating blocks and the sliding movement of the drive motors, cutting of any shape within the circular area can be achieved.

[0019] 2. Based on the different shapes of the window panel cutting, the clamping method between the rubber pad and the material feeding area is changed so that the clamping point is close to the stress point of the cutting edge, which is more conducive to maintaining stability during window panel cutting. The rotation of the grinding rail causes the edge wheel to roll in line with the outline of the window under the action of the component force. The upper chamfering wheel and the lower chamfering wheel chamfer and grind the edge of the window, realizing automated production of cutting and chamfering. Attached Figure Description

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.

[0031] Please see Figures 1-8This invention provides a technical solution: a processing device for plastic optical windows with stable clamping, comprising a support frame, a moving module 3, a window plate to be cut, a material conveyor, a cutting wire 13, and two sets of drive motors 12 for driving the cutting wire 13 to cut. The moving module 3 is located on one side of the support frame, and the material conveyor is located on the side of the moving module 3 away from the base 1. The support frame is provided with the base 1 and a hydraulic cylinder (not shown in the figure), the hydraulic cylinder is located below the base 1, the window plate is located on the base 1, and the base 1 is provided with a feeding roller 2 and auxiliary grippers (Figure 1). (Not shown in the drawing), a motor for driving rotation is provided on one side of the feeding roller 2. A cutting frame 4 is provided on the moving module 3. The cutting frame 4 is provided with a cutting mechanism, an upper clamping group 14, a lower clamping group 15, and an edge grinding mechanism. The upper clamping group 14 and the lower clamping group 15 have the same structure and are arranged symmetrically above and below. The window plate to be cut is placed on the base 1. The control system drives the feeding roller 2 to rotate by controlling the motor. The feeding roller 2 pushes the window plate out of the base 1. The auxiliary gripper clamps hold and fix the window plate that extends out of the base 1.

[0032] The cutting frame 4 is U-shaped and hollow inside. The cutting mechanism includes an upper synchronous rotating block 901 and a lower synchronous rotating block 902, which are rotatably connected to the cutting frame 4. The upper and lower synchronous rotating blocks 901 and 902 are symmetrically installed vertically. A driven sprocket is connected to the side of each of the upper and lower synchronous rotating blocks 901 and 902 that contacts the cutting frame 4. The driven sprockets are located inside the cutting frame 4. The cutting mechanism includes a first motor 5 and a rotating shaft 6, which is mounted on the cutting frame 4. Inside, the rotating shaft 6 is connected to the first motor 5. A drive sprocket 7 is set on the rotating shaft 6 at a position corresponding to the height of the two driven sprockets. Each drive sprocket 7 is connected to a driven sprocket at the same height by a chain 8. The moving module 3 drives the cutting frame 4 to move and change position. Under the action of the control system, the first motor 5 drives the rotating shaft 6 to rotate. The two drive sprockets 7 on the rotating shaft 6 rotate synchronously. The drive sprockets 7 drive the two driven sprockets to rotate through the chain 8. The upper synchronous rotating block 901 and the lower synchronous rotating block 902 can rotate synchronously at the same time.

[0033] Both the upper synchronous rotating block 901 and the lower synchronous rotating block 902 are equipped with a slide rail 10 and a lead screw 11. Inside the upper synchronous rotating block 901 and the lower synchronous rotating block 902, corresponding to the position of the lead screw 11, a first servo motor is installed. Two first servo motors are respectively connected to the two lead screws 11. Two sets of drive motors 12 are slidably mounted on the two slide rails 10. Each drive motor 12 has a threaded hole that mates with the lead screw 11, and the threaded hole is threadedly connected to the lead screw 11. The two sets of drive motors 12 are installed vertically and vertically. A cutting wire 13 is installed between the two sets of drive motors 12. The upper synchronous rotating block 901 and the lower synchronous rotating block 902... While rotating, the control system simultaneously powers on the two first servo motors. The first servo motors drive the lead screw 11 to rotate, and the lead screw 11 causes the two sets of drive motors 12 to slide along the slide rail 10 through threaded transmission. The rotation of the upper synchronous rotating block 901 and the lower synchronous rotating block 902 causes the area covered by the slide rail 10 to form a circular area. The first servo motors control the movement of the drive motors 12 so that the cutting wire 13 can follow any trajectory on the viewing window. Through the coordination of the rotation of the upper synchronous rotating block 901 and the lower synchronous rotating block 902 and the sliding movement of the drive motor 12, cutting of any shape within the circular area can be achieved.

[0034] The upper clamping assembly 14 includes an electric actuator 16 and an integrated chamber 17. The piston of the electric actuator 16 passes through the cutting mechanism. The integrated chamber 17 is mounted on the electric actuator 16. A first clamping arm 181 and a second clamping arm 182 are rotatably arranged inside the integrated chamber 17. The first clamping arm 181 is located on the side where the upper clamping assembly 14 and the lower clamping assembly 15 are close to each other, and the second clamping arm 182 is located on the side where the upper clamping assembly 14 and the lower clamping assembly 15 are far apart from each other. Each end is connected to a rubber pad 19, and the four rubber pads 19 are located on the same plane. A second servo motor 20 is provided on the outside of the integrated compartment 17. A driven bevel gear is provided at the end of the first clamping arm 181 and the second clamping arm 182 that are close to each other. The driven bevel gear is located at the rotational connection between the first clamping arm 181 and the second clamping arm 182 and the integrated compartment 17. A driving bevel gear 21 is mounted on the second servo motor 20. The driving bevel gear 21 meshes with the two driven bevel gears. Before cutting, if the window panel to be cut is rectangular, the second servo motor 20 drives the active bevel gear 21 to rotate. The active bevel gear 21 drives two driven bevel gears to rotate, and the two driven bevel gears drive the first clamping arm 181 and the second clamping arm 182 to move in opposite directions, so that the four rubber pads 19 on the first clamping arm 181 and the second clamping arm 182 are close to the four corners of the rectangle. If the window panel to be cut is circular, the second servo motor 20 drives the first clamping arm 181 and the second clamping arm 182 to rotate into a perpendicular state, and the four rubber pads 19 are close to the four quadrants of the circle. The electric push rod 16 pushes the integrated chamber 17 to move, so that the rubber pads 19 on the upper clamping group 14 and the lower clamping group 15 contact the window panel and clamp the window panel. Depending on the shape of the window panel to be cut, the clamping method of the rubber pads 19 and the unloading area is changed so that the clamping point is close to the stress point of the cutting edge, which is more conducive to maintaining stability during the cutting of the window panel.

[0035] The edge grinding mechanism is mounted on the lower synchronous rotating block 902. The mechanism includes a grinding rail 22 and a slider 23. The grinding rail 22 is located on the lower synchronous rotating block 902, and the slider 23 is slidably mounted within the grinding rail 22. An electromagnetic spring 29 is installed between the slider 23 and the lower synchronous rotating block 902. A spline shaft 25 is mounted on the slider 23. Baffles are provided at the upper and middle parts of the spline shaft 25. A small motor 24 is installed inside the slider 23 and connected to the spline shaft 25. Between the two baffles of the spline shaft 25, from top to bottom, are arranged an upper chamfering wheel 26, a contact wheel 28, and a lower chamfering wheel 27. The upper and lower chamfering wheels 26 and 27 are slidably mounted on the spline shaft 25. The contact wheel 28 is sleeved on the spline shaft 25. Between the upper and lower chamfering wheels 26 and 27 and the two baffles… Each component is equipped with a small spring. After the window is cut and the material is cut, the upper clamping group 14 and the lower clamping group 15 lower the window to the height of the edge grinding mechanism. Then, the first motor 5 continues to drive the upper synchronous rotating block 901 and the lower synchronous rotating block 902 to rotate. At the same time, the electromagnetic spring 29 is energized. Under the action of electromagnetic force, the electromagnetic spring 29 begins to tighten. The edge contact wheel 28 contacts the edge of the window. The small motor 24 drives the spline shaft 25 to rotate rapidly. The spline shaft 25 causes the upper chamfering wheel 26 and the lower chamfering wheel 27 to rotate. The grinding rail 22 rotates, causing the edge contact wheel 28 to roll along the contour of the window under the action of the component force. The upper chamfering wheel 26 and the lower chamfering wheel 27 chamfer and grind the edge of the window. After grinding, the hydraulic cylinder pushes the window onto the material conveyor, completing the cutting of one window.

[0036] Processing method for a processing apparatus for a plastic optical window with stable clamping:

[0037] S1: The viewing window is set on the base 1. The feeding roller 2 pushes the viewing window to extend out of the base 1. The auxiliary gripper clamps the part of the viewing window that extends out of the base 1 for stability.

[0038] S2: The moving module 3 drives the cutting frame 4 to move, and the upper clamping group 14 and the lower clamping group 15 adjust the state of the first clamping arm 181 and the second clamping arm 182 according to the size of the cutting shape in the window and clamp the cutting part.

[0039] S3: The cutting mechanism uses cutting wire 13 to cut the viewing window panel;

[0040] S4: After cutting is completed, the upper clamping group 14 and the lower clamping group 15 drive the unloading part to descend, and the hydraulic cylinder pushes the viewing window onto the material conveyor.

[0041] The working principle of this invention is as follows: The window panel to be cut is placed on the base 1. The control system drives the feeding roller 2 to rotate by controlling the motor. The feeding roller 2 pushes the window panel out of the base 1. The auxiliary gripper clamps and fixes the window panel that extends out of the base 1. The moving module 3 drives the cutting frame 4 to move and change position. The first motor 5 drives the rotating shaft 6 to rotate under the action of the control system. The two active sprockets 7 on the rotating shaft 6 rotate synchronously. The active sprockets 7 drive the two driven sprockets to rotate through the chain 8. The upper synchronous rotating block 901 and the lower synchronous rotating block 902 can rotate synchronously at the same time.

[0042] While the upper synchronous rotating block 901 and the lower synchronous rotating block 902 are rotating, the control system simultaneously powers on the two first servo motors. The first servo motors drive the lead screw 11 to rotate, and the lead screw 11 drives the two sets of drive motors 12 to slide along the slide rail 10 through threaded transmission. The rotation of the upper synchronous rotating block 901 and the lower synchronous rotating block 902 causes the area covered by the slide rail 10 to form a circular area. The first servo motors control the drive motors 12 to move, causing the cutting wire 13 to walk on any trajectory on the viewing window. Through the coordination of the rotation of the upper synchronous rotating block 901 and the lower synchronous rotating block 902 and the sliding motion of the drive motors 12, cutting of any shape within the circular area can be achieved.

[0043] Before cutting, if the window panel to be cut is rectangular, the second servo motor 20 drives the active bevel gear 21 to rotate. The active bevel gear 21 drives two driven bevel gears to rotate, and the two driven bevel gears drive the first clamping arm 181 and the second clamping arm 182 to move in opposite directions, so that the four rubber pads 19 on the first clamping arm 181 and the second clamping arm 182 are close to the four corners of the rectangle. If the window panel to be cut is circular, the second servo motor 20 drives the first clamping arm 181 and the second clamping arm 182 to rotate into a perpendicular state, and the four rubber pads 19 are close to the four quadrants of the circle. The electric push rod 16 pushes the integrated chamber 17 to move, so that the rubber pads 19 on the upper clamping group 14 and the lower clamping group 15 contact the window panel and clamp the window panel. Depending on the shape of the window panel to be cut, the clamping method of the rubber pads 19 and the unloading area is changed so that the clamping point is close to the stress point of the cutting edge, which is more conducive to maintaining stability during the cutting of the window panel.

[0044] After the window is cut and the material is cut, the upper clamping group 14 and the lower clamping group 15 lower the window to the height of the edge grinding mechanism. Then, the first motor 5 continues to drive the upper synchronous rotating block 901 and the lower synchronous rotating block 902 to rotate. At the same time, the electromagnetic spring 29 is energized. Under the action of electromagnetic force, the electromagnetic spring 29 begins to tighten. The edge contact wheel 28 contacts the edge of the window. The small motor 24 drives the spline shaft 25 to rotate quickly. The spline shaft 25 causes the upper chamfering wheel 26 and the lower chamfering wheel 27 to rotate. The grinding rail 22 rotates, causing the edge contact wheel 28 to roll along the contour of the window under the action of the component force. The upper chamfering wheel 26 and the lower chamfering wheel 27 chamfer and grind the edge of the window. After grinding, the hydraulic cylinder pushes the window onto the material conveyor, completing the cutting of one window.
