[0001] This utility model relates to the field of polishing equipment, and more specifically, it relates to a polishing equipment for the inner surface of orthokeratology lenses. Background Technology

[0002] The processing of orthokeratology lenses usually requires the use of a polishing machine to polish the inner surface of the lens. However, the part of the existing polishing machine that holds the lens can usually only be kept in one position, resulting in an uneven polishing effect on the overall inner surface of the lens.

[0003] Therefore, a new solution is needed to address this problem. Utility Model Content

[0004] The purpose of this invention is to provide a device for polishing the inner surface of orthokeratology lenses in order to solve the above-mentioned problems.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a corneal reshaping lens inner surface polishing device, including a support base and a polishing table mounted on the support base; a polishing rod is rotatably connected inside the polishing table; a first connecting rod is rotatably connected to the support base, a second connecting rod is rotatably connected to one end of the first connecting rod, a first motor is fixedly connected to the second connecting rod, and the output end of the first motor is connected to a clamping mechanism, the clamping mechanism being used to clamp the corneal reshaping lens wax adhesive clamp;

[0006] The end of the first connecting rod away from the second connecting rod is rotatably connected to a transmission rod, and the side of the transmission rod away from the first connecting rod is rotatably connected to a rotating rod, which is rotatably engaged with the support base;

[0007] The support base is equipped with a drive mechanism to drive the polishing rod and the rotating rod to rotate.

[0008] The clamping mechanism includes a clamping seat fixedly connected to the output end of the first motor, and two clamping clips are fixedly connected to the clamping seat. A slot for clamping the corneal reshaping lens wax adhesive clamp is formed between the two clamping clips.

[0009] The present invention is further configured such that: the driving mechanism includes a second motor fixed in the support base, the polishing rod is fixedly connected to the output end of the second motor, and the second motor drives the rotating rod to rotate through a transmission mechanism.

[0010] The present invention is further configured such that: the transmission mechanism includes a first bevel gear fixed to the output end of the second motor, the first bevel gear meshing with a second bevel gear, the second bevel gear being coaxially provided with a driving gear, the driving gear meshing with a driven gear, the driven gear being fixedly connected to a support rod, and the end of the support rod away from the driven gear being fixedly connected to a rotating rod.

[0011] The present invention is further configured such that the support rod and the transmission rod are respectively disposed on both sides of the rotating rod.

[0012] The present invention is further configured such that the diameter and number of teeth of the driven gear are both greater than the diameter and number of teeth of the driving gear.

[0013] The present invention is further configured such that: the polishing rod is provided with a polishing cloth, and a guide tube is provided on one side of the polishing table.

[0014] In summary, this utility model has the following beneficial effects:

[0015] The clamping mechanism holds the orthokeratology lens. Rotating the second connecting rod causes the orthokeratology lens to come into contact with the polishing rod, activating the device. The polishing rod rotates to polish the inner surface of the orthokeratology lens, while the clamping mechanism rotates in the opposite direction to the polishing rod under the drive of the first motor, thus improving the polishing effect. The rotating rod rotates under the drive mechanism, which in turn drives the transmission rod that works in conjunction with the rotating rod to rotate. The rotation of the transmission rod causes the first connecting rod to sway left and right, making the orthokeratology lens sway left and right with the first connecting rod. This increases the polishing area of ​​the orthokeratology lens, polishing the inner surface of the lens from multiple directions, making the polishing more thorough and uniform.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, the orthokeratology lens inner surface polishing device includes a support base 1 and a polishing table 2 mounted on the support base 1. A polishing rod 3 is rotatably connected inside the polishing table 2, and the surface of the polishing rod 3 is covered with a polishing cloth 17, achieving precision polishing of the inner surface of the orthokeratology lens through flexible contact. A conduit 18 is provided on one side of the polishing table 2 for collecting and discharging waste liquid generated during the polishing process.

[0022] like Figure 1 , Figure 2 and Figure 3 As shown, a first connecting rod 4 is rotatably connected to the support base 1. One end of the first connecting rod 4 is rotatably connected to a second connecting rod 5 via a rotating shaft. A first motor 6 is fixedly mounted on the second connecting rod 5. The output end of the first motor 6 is fixedly connected to the clamping mechanism via a coupling. The clamping mechanism includes a clamping base 9 and two symmetrically arranged clamping clips 10. The clamping base 9 has a disc-shaped structure. The two clamping clips 10 are fixed to the front end of the clamping base 9 by bolts, forming a slot between them for accommodating the corneal reshaping lens wax adhesive clamp. The wax adhesive clamp is a commonly used optical component clamping tool in the prior art. The corneal reshaping lens is fixed to the surface of the clamp through a wax layer. The protrusions on both sides of the clamp can be embedded into the slots of the clamping clips 10, and clamping is achieved by the elastic deformation of the clamping clips 10.

[0023] like Figure 1 , Figure 2 and Figure 3 As shown, the end of the first connecting rod 4 furthest from the second connecting rod 5 is rotatably connected to the transmission rod 7. The other end of the transmission rod 7 is connected to the rotating rod 8 via a spherical bearing. The bottom of the rotating rod 8 is fixed inside the support base 1 via a bearing seat. The support base 1 houses a drive mechanism, including a second motor 12 and a transmission mechanism. The output end of the second motor 12 extends upward and is fixedly connected to the polishing rod 3, while simultaneously driving the rotating rod 8 to rotate via the transmission mechanism.

[0024] like Figure 1 , Figure 2 and Figure 3As shown, the transmission mechanism includes a first bevel gear 13, a second bevel gear 14, a driving gear 15, and a driven gear 16. The first bevel gear 13 is fixed to the middle of the output shaft of the second motor 12 and meshes with the vertically arranged second bevel gear 14 to achieve a 90° change in the power direction. The second bevel gear 14 is coaxially fixed to the driving gear 15, which meshes with the driven gear 16. The driven gear 16 is fixedly connected to the bottom of the rotating rod 8 via a support rod 19. The driven gear 16 has a larger diameter and a larger number of teeth than the driving gear 15, forming a speed reduction transmission, so that the rotational speed of the rotating rod 8 is lower than the rotational speed of the polishing rod 3. The support rod 19 and the transmission rod 7 are located on the left and right sides of the rotating rod 8, respectively. When the rotating rod 8 rotates, the transmission rod 7 drives the first connecting rod 4 to reciprocate, causing the clamping mechanism to swing left and right synchronously.

[0025] The workflow of this embodiment is as follows:

[0026] Mounting process: The orthokeratology lens is fixed to the surface of the wax adhesive clamp through the wax layer. The protrusions on both sides of the clamp are inserted into the slots of the clamping clip 10, and the clamp is clamped by the elastic force of the clamping clip 10.

[0027] Blade adjustment: Rotate the second link 5 to bring the inner surface of the orthokeratology lens into contact with the polishing cloth 17 on the surface of the polishing rod 3, and control the polishing pressure by finely adjusting the angle of the second link 5.

[0028] Polishing operation: The second motor 12 is started, and its output shaft drives the polishing rod 3 to rotate at high speed. At the same time, through the transmission of the first bevel gear 13, the second bevel gear 14, the driving gear 15, and the driven gear 16, the rotating rod 8 rotates at a lower speed. The rotating rod 8 drives the first connecting rod 4 to reciprocate through the transmission rod 7, causing the orthokeratology lens to sway left and right during the polishing process. Meanwhile, the first motor 6 can drive the clamping mechanism to rotate, realizing the polishing of the inner surface.

[0029] Waste liquid treatment: Polishing liquid is continuously flushed through conduit 18 to the polishing area, carrying grinding debris into the collection system to ensure a clean polishing environment.

[0030] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
