Description

Technical Field

[0001] This utility model relates to the field of mirror surface polishing technology, and in particular to a mirror surface polishing device. Background Technology

[0002] Mirror surface polishing equipment is a precision machining tool primarily used to achieve an extremely smooth surface finish on materials. Through motion control, it can polish complex curved surfaces such as metals, optical lenses, semiconductor wafers, and precision molds. Equipped with a flexible polishing tool head and pressure adjustment technology, the equipment can compensate for workpiece deformation errors in real time, ensuring uniform pressure distribution. This meets the stringent requirements for mirror-level surface finish in high-end manufacturing fields such as optical components and chip packaging substrates, significantly improving product light transmittance, wear resistance, and service life. It is a key technological equipment in the field of precision machining.

[0003] In existing technologies, a polishing cloth is installed on the surface of a mirror surface polishing device. Then, the optical mirror is placed under a pressure workpiece, which applies downward vertical pressure to the mirror surface, causing the lower surface of the mirror to adhere tightly to the surface of the polishing cloth. The position of the retainer is then adjusted, and the polishing cloth rubs against the mirror surface during rotation. However, the retainer is generally fixed with bolts, so during mirror polishing, the polishing cloth can only rub within a certain range. This results in a large area of ​​the polishing cloth being wasted without being used, causing a great waste of resources. Utility Model Content

[0004] Therefore, it is necessary to provide a mirror surface polishing device, which addresses the issue that the cage structure is generally fixed with bolts, and during the mirror polishing process, the polishing cloth can only be rubbed within a certain range, resulting in a large area of ​​the polishing cloth being scrapped without being used, which greatly wastes resources.

[0005] A mirror surface polishing apparatus includes: a polishing assembly, the polishing assembly including a controller, a turntable and a support plate, the turntable being located inside the controller and rotating, and the support plate being mounted on the controller and extending upward toward the side close to the turntable;

[0006] A connecting frame is mounted on the support plate and located above the turntable. A guide frame is movably connected to one side of the connecting frame, and a pressure plate is attached to one side of the guide frame. The pressure plate slides on the upper surface of the connecting frame.

[0007] A drive assembly, which is disposed on the support plate, is used to push the guide frame.

[0008] In one embodiment, the support plate is inserted into the controller from below, and the extension direction of the support plate can be adjusted by bolts.

[0009] In one embodiment, the side of the connecting frame inserted into the support plate is immovable, and the middle part of the guide frame swings around the connecting frame.

[0010] In one embodiment, the drive assembly includes a motor fixed below the guide frame, the output end of the motor being driven to a wheel through the guide frame, a connecting rod being movably connected to the upper surface of the wheel, and one end of the connecting rod being interactively connected to the guide frame.

[0011] In one embodiment, one inner wall of the guide frame is arc-shaped, and the inner diameter of the arc of the guide frame is larger than the outer diameter of the pressure plate.

[0012] In one embodiment, guide rods are movably inserted into both sides of the guide frame, and guide discs are movably connected below the guide rods. The two guide discs are respectively located on both sides of the pressure plate and rotate.

[0013] In one embodiment, the surface of the guide rod is provided with a limiting disc and a threaded disc, with the threaded disc located above the limiting disc.

[0014] In one embodiment, a knob is fixedly connected to the upper end of the guide rod, and the knob rotates coaxially with the guide rod and the guide disc.

[0015] Beneficial effects

[0016] 1. When the turntable rotates, the circumference of the contact surface between the lower sides of the pressure plate and the turntable is not consistent. This causes the pressure plate to rotate during the rotation of the turntable, providing rotational friction to the mirror surface and making the mirror surface more evenly rubbed. The drive component pushes the guide frame to swing around the connecting frame as the axis. During the swinging process, the guide frame moves the pressure plate away from and closer to the turntable axis as the base point, which greatly increases the contact area between the polishing cloth and the pressure plate, increases the usable area of ​​the polishing cloth, and reduces the waste of resources.

[0017] 2. The guide rod has threads on its surface, located above the limiting plate and below the knob. Rotating the threaded plate that meshes with the guide rod moves it downwards. The threaded plate and the limiting plate clamp the guide frame, and the guide rod slides along the inside of the guide frame. The distance between the two guide rods can be adjusted, and pressure plates of different diameters can be limited, improving the flexibility of the guide frame. The guide plate and the guide rod are connected at their axis by a bearing, which reduces the friction between the guide plate and the guide rod. When the pressure plate rotates, the guide plate rotates on its own axis. Attached Figure Description

[0030] The following is combined Figures 1-4 This invention describes a mirror surface polishing device.

[0031] In one embodiment, a mirror surface polishing apparatus includes: a polishing assembly 100, a connecting frame 200, and a driving assembly 400. The polishing assembly 100 includes a controller 101, a turntable 102, and a support plate 103. The turntable 102 rotates inside the controller 101. The support plate 103 is mounted on the controller 101 and extends upward toward the side near the turntable 102. The connecting frame 200 is disposed on the support plate 103 and located above the turntable 102. A guide frame 300 is movably connected to one side of the connecting frame 200. A pressure plate 500 is attached to one side of the guide frame 300 and slides on the upper surface of the connecting frame 200. The driving assembly 400 is disposed on the support plate 103 for pushing the guide frame 300.

[0032] In this embodiment, the controller 101, the turntable 102 and the support plate 103 constitute the polishing assembly 100. The drive unit of the turntable 102 is installed inside the controller 101. The turntable 102 can rotate on its own. The surface of the turntable 102 is attached to the polishing cloth. The bottom of the polishing cloth is attached to the surface of the turntable 102 and rotates with the turntable 102, attaching the mirror surface to the bottom of the pressure plate 500. The pressure plate 500 is placed on the turntable 102, attaching the mirror surface to the polishing cloth.

[0033] When the turntable 102 rotates, one side of the pressure plate 500 will come into contact with the guide frame 300. The guide frame 300 restricts the pressure plate 500 above the turntable 102, causing the polishing cloth to rub against the pressure plate 500 continuously. The pressure plate 500 provides a relatively stable vertical downward force to the mirror surface, making the contact surface between the polishing cloth and the mirror surface more stable.

[0034] When the turntable 102 rotates, the circumference of the contact surface between the lower sides of the pressure plate 500 and the turntable 102 is not consistent, which causes the pressure plate 500 to rotate during the rotation of the turntable 102, providing rotational friction to the mirror surface and making the mirror surface more evenly rubbed.

[0035] The drive assembly 400 pushes the guide frame 300 to swing around the connecting frame 200. During the swing, the guide frame 300 moves the pressure plate 500 away from and closer to the axis of the turntable 102, which greatly increases the contact area between the polishing cloth and the pressure plate 500, increases the usable area of ​​the polishing cloth, and reduces the waste of resources.

[0036] like Figure 1 , Figure 2 and Figure 3 The support plate 103 is inserted into the controller 101 below. The extension direction of the support plate 103 can be adjusted by bolts. The side of the connecting frame 200 inserted into the support plate 103 is immovable. The middle part of the guide frame 300 swings with the connecting frame 200 as the core.

[0037] In this embodiment, the support plate 103 consists of a support column and an extension plate. The extension plate is installed above the support column, and the connection between the support column and the extension plate is fixed by bolts. The spacing between the multiple bolts is equal. By rotating the connection direction between the extension plate and the support column below, the angle of the extension plate can be adjusted to change the support angle of the connecting frame 200 and the guide frame 300.

[0038] The connection between the connecting frame 200 and the guide frame 300 is fixed by a pin. The pin is polygonal, which makes it difficult for the connecting frame 200 to rotate after it is fixed inside the guide frame 300. When the pin at the connection between the connecting frame 200 and the guide frame 300 is pulled out, the swing direction of the connecting frame 200 can be adjusted, thereby improving the flexibility of the connecting frame 200 and the guide frame 300.

[0039] like Figure 1 , Figure 2 and Figure 3 The drive assembly 400 includes a motor 401 fixed below the guide frame 300. The output end of the motor 401 passes through the guide frame 300 and is connected to a wheel 402. A connecting rod 403 is movably connected to the upper surface of the wheel 402. One end of the connecting rod 403 is interactively connected to the guide frame 300. One inner wall of the guide frame 300 is arc-shaped, and the arc-shaped inner diameter of the guide frame 300 is larger than the outer diameter of the pressure plate 500.

[0040] In this embodiment, the upper part of the wheel 402 and the guide frame 300 are movably connected by a connecting column and a connecting rod 403. The connecting column above the wheel 402 is located on one side of the axis. When the wheel 402 rotates, the connecting rod 403 will stretch the guide frame 300 in a directional manner, causing the guide frame 300 to swing around the connecting frame 200 as the axis. The guide frame 300 pushes the pressure plate 500 to move, and the guide frame 300 restricts the pressure plate 500 in the groove, limiting the friction range of the pressure plate 500.

[0041] like Figure 2 , Figure 3 and Figure 4 Guide rods 301 are movably inserted into both sides of the guide frame 300. Guide discs 302 are movably connected to the lower part of the guide rods 301. The two guide discs 302 are located on both sides of the pressure plate 500 and rotate. The surface of the guide rods 301 is provided with a limiting disc 303 and a threaded disc 304. The threaded disc 304 is located above the limiting disc 303. A knob 305 is fixedly connected to the upper end of the guide rods 301. The knob 305 rotates coaxially with the guide rods 301 and the guide discs 302.

[0042] In this embodiment, the surface of the guide rod 301 is threaded, with the thread located above the limiting disc 303 and below the knob 305. Rotating the threaded disc 304, which meshes with the guide rod 301, moves it downwards. The threaded disc 304 and the limiting disc 303 clamp the guide frame 300. The guide rod 301 slides along the inside of the guide frame 300, which can adjust the distance between the two guide rods 301 and limit the pressure plate 500 of different diameters, improving the guiding flexibility of the guide frame 300. The guide disc 302 is connected to the axis of the guide rod 301 by a bearing, which can reduce the friction between the guide disc 302 and the guide rod 301. When the pressure plate 500 rotates, the guide disc 302 rotates on its own axis.

[0043] Working principle:

[0044] The controller 101 drives the turntable 102 to rotate. The support plate 103 supports the connecting frame 200, the guide frame 300, and the drive assembly 400. The arc of the guide frame 300 faces the rotation direction of the turntable 102. The turntable 102 pushes the upper pressure plate 500 close to the guide frame 300. The guide frame 300 limits the pressure plate 500. The pressure plate 500 rotates on one side of the guide frame 302. The drive assembly 400 drives the guide frame 300 to swing around the connecting frame 200 as the axis. The guide frame 300 drives the pressure plate 500 to swing on the upper surface of the connecting frame 200. The pressure plate 500 causes the mirror surface to rub against the polishing cloth below in multiple directions, making the mirror surface friction more uniform, improving polishing efficiency, and increasing the contact area between the polishing cloth and the pressure plate 500, thereby increasing the utilization rate of the polishing cloth and reducing resource waste.

[0045] It should be noted that the controller 101 and motor 401 mentioned above are all devices with relatively mature existing technology. The specific models can be selected according to actual needs. At the same time, the controller 101 and motor 401 can be powered by the built-in power supply or by the mains power. The specific power supply method is selected according to the situation and will not be elaborated here.

[0046] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the appended claims.
