Abstract
Description
Technical Field
[0001] This invention relates to the field of orthokeratology lens production equipment technology, specifically to a waxing device that can control the wax thickness during the self-waxing of lenses in the process of orthokeratology lens production. Background Technology
[0002] As is well known, the production process of orthokeratology lenses involves numerous steps and is highly automated and precise, encompassing materials science, precision engineering, and quality control. Specifically, before cutting the back surface of the lens material and the front surface of the semi-finished lens, a waxing process is required for fixation and protection. This is followed by turning, polishing, and finally dewaxing and cleaning. Given current technology, the core technical challenge in the waxing process of orthokeratology lens production is achieving micron-level uniformity in the wax layer thickness. While controlling the wax application process, it is also necessary to avoid contamination or damage to the optical zone of the lens. Because the fluidity of the wax material is unstable after heating, it is prone to local accumulation or uneven thickness due to temperature fluctuations. Waxing is only allowed to cover the non-optical zone at the edge of the lens (for subsequent grinding and polishing positioning). If the wax material seeps into the optical zone, it will directly affect the light transmittance and refractive accuracy of the lens. It is necessary to accurately define the boundary between the wax layer and the optical zone, and also to prevent the wax liquid from overflowing due to surface tension. Therefore, a waxing device that can automatically apply wax conveniently, reliably, and stably, while also improving the uniformity of waxing on orthokeratology lenses and ensuring precise control of wax thickness, is needed, and has a high working efficiency.

[0020] It should be noted that when a component is considered to be "connected" to another component, it can be directly connected to and integrated with the other component, or there may be an intervening component present. The terms "mounted," "one end," "the other end," and similar expressions used in this document are for illustrative purposes only.
[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this applies. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.
[0022] like Figure 1-2 As shown, a preferred embodiment of the present invention provides a waxing device for controlling wax thickness, including a mounting base body 1 and an upper clamping mechanism and a lower clamping mechanism disposed on the mounting base body 1. The upper clamping mechanism includes an upper clamping body base 2, an upper clamping head assembly 3, and an adjusting assembly 4. The upper clamping head assembly 3 and the adjusting assembly 4 are both mounted on the upper clamping body base 2. The upper clamping head assembly 3 includes an upper clamping head body 31 and a movable connecting assembly 32. The upper clamping head body 31 is slidably connected to the upper clamping body base 2 through the movable connecting assembly 32. The lower clamping mechanism includes a lower clamping body base 5, a lower clamping head body 6, and a buffer connecting seat 7. One end of the adjusting assembly 4 is movably connected to the upper clamping body base 2, and the other end is connected to the lower clamping body base 5. The lower clamping head body 6 is connected to the lower clamping body base 5. The upper clamp 31 is connected to the buffer connecting seat 7, which is connected to the lower clamp base 5. The movable connecting component 32 is used to drive the upper clamp 31 to make a vertical downward movement towards the lower clamp 6. The adjusting component 4 is used to adjust the upper clamp base 2 to make a vertical downward movement towards the lower clamp 6. When waxing, relying on manual or semi-automatic equipment for alignment is prone to errors, resulting in uneven lens thickness and substandard optical performance. If the wax thickness cannot be adjusted, the required wax thickness cannot be obtained according to the customer's needs. The waxing device provided in this embodiment of the invention can achieve precise thickness control, ensuring that the wax thickness adjustment during material waxing can be accurate to within 0.01mm.
[0023] refer to Figure 1-2As shown, in a further preferred embodiment, the upper clamp body 31 includes a clamp connecting seat 33 and an upper clamp body 310. One end of the clamp connecting seat 33 is slidably connected to the upper clamp base 2 via a movable connecting component. The other end of the clamp connecting seat 33 is provided with a connection position for connecting the upper clamp body 310. The connection position is used to correspondingly install and connect the upper clamp body 310. The clamp body is provided with an arc-shaped convex surface. The arc-shaped convex surface is provided to correspond to pressing down the contact lens clip material so that the required curved surface can be formed after waxing. The connection position is provided to ensure that the upper clamp body 310 can be stably connected to the connection position. In the specific process of waxing, it is necessary to ensure the positioning and fixation of the upper clamp body and the lower clamp body to ensure that the waxing is carried out smoothly, improve the waxing accuracy, and obtain a uniform wax thickness.
[0024] refer to Figure 1-2 As shown, in a preferred embodiment, the movable connecting component 32 includes a connecting plate 34 and a power drive component, which is a drive cylinder. The upper clamping base 2 has sliding connecting rails 21 on both sides. The inner walls of both sides of the connecting plate 34 have corresponding inner wall connecting surfaces for the sliding connecting rails 21. The drive cylinder can be mounted on the upper clamping base 2. The power output acts on the connecting plate 34, pushing it to slide smoothly on the sliding connecting rails 21. The corresponding sliding connecting rails and inner wall connecting surfaces ensure that the movable connecting component can smoothly drive the upper clamping body to move, ensuring precise alignment between the upper and lower clamping bodies, and ensuring uniform wax thickness during waxing, reducing localized accumulation and uneven wax thickness.
[0025] refer to Figure 1-2 As shown, in a preferred embodiment, the upper chuck body 310 is provided with an upper chuck position 35 for accommodating the carrier. The upper chuck body 310 and the chuck connecting seat 33 are detachably connected. The detachable connection structure allows for the replacement of the upper chuck body model, facilitating repair. Of course, in another embodiment, it can also be set as an integrally formed connection structure.
[0026] refer to Figure 1-2As shown, in a further preferred embodiment, the adjustment component 4 includes an adjustment connecting seat 41 and an adjusting member. The upper end of the adjustment connecting seat 41 is slidably connected to the lower part of the upper clamping base 2. The upper end of the adjustment connecting seat 41 is equipped with a connecting adjusting member, which is a bolt adjusting member. The bolt adjusting member has a first bolt adjusting member 42 and a second bolt adjusting member 43. The adjusting member is connected to the lower part of the upper clamping base through an internal connecting rod. The adjusting member is also connected to a dial indicator 8. The bolt adjusting member is a manually adjustable member. When it is necessary to ensure the thickness of the pressed wax, the downward pressing distance of the upper clamping body can be slightly adjusted by hand-tightening the bolt adjusting member to ensure that the wax thickness adjustment range can be controlled within 0.01mm. The downward displacement of the upper clamping base can also be adjusted according to the wax thickness required by the customer to ensure the precise alignment of the upper and lower clamping bodies and ensure that the wax thickness is uniform during waxing.
[0027] refer to Figure 1-2 As shown, in the preferred embodiment, the bottom of the adjusting connecting seat 41 is slidably connected to the lower clamping base 5. A track connecting seat is provided on the connecting end face of the bottom of the adjusting connecting seat 41 and the lower clamping base 5. A power mechanism is provided on one side of the adjusting connecting seat 41. The power mechanism is a drive cylinder, which is a conventional cylinder. The adjusting connecting seat can move left and right on the lower clamping base, and the upper clamping head body can be adjusted to move left and right to ensure that the pressing position is accurately aligned. In order to accurately measure the movement distance, the adjusting connecting seat can also be connected to a dial indicator to calibrate the movement distance, improve the accuracy of the device, and also ensure that the wax thickness is uniform during waxing and reduce local errors.
[0028] refer to Figure 1-2 As shown, in a further preferred embodiment, the lower clamp body 6 is provided with a clamp body seat 61 and a lower clamp body 60. The lower clamp body 60 is provided with a lower chuck position. The surface of the lower chuck position is a slightly curved surface, which is to correspond to the design of the upper clamp body and facilitate the formation of the curved surface after waxing the contact lens clip material. The lower end of the clamp body seat 61 is connected to the buffer connecting seat 7. The buffer connecting seat 7 is provided with a buffer connector 71. The buffer connector 71 is an elastic element. Specifically, it can be a spring-type elastic element or a hydraulically structured elastic buffer element. The upper end of the buffer connector 71 is provided with a connecting support 72 for connecting the clamp body seat 61. The buffer connector 71 can extend and retract slightly up and down. When waxing the contact lens clip material, when the upper clamp body presses down on the lower clamp body, a uniform wax thickness can be obtained, ensuring that the wax thickness is uniform and that the wax layer is evenly distributed on the clip material surface, avoiding local accumulation.
[0029] refer to Figure 1-2As shown, in a further preferred embodiment, the buffer connector 71 is built into the buffer connector base 7 through the connecting kit 9. The bottom of the connecting kit 9 extends to the bottom position near the lower clamp base. The connecting kit can stabilize the connection structure of the buffer connector and also ensure the structural stability of the lower clamp body, improve the overall device accuracy, and ensure that it can be accurately aligned and docked with the upper clamp body, so that the waxing can be carried out smoothly. This is because the accuracy of the device directly determines the accuracy of waxing when fastening the material.
[0030] refer to Figure 1-2 As shown, in a further preferred embodiment, the upper end of the buffer connecting seat 7 is provided with a connecting groove 73, which is connected to the chuck body seat. Below the connecting groove 73, there is a kit space for interference fit connection of the connecting kit 9. The connecting groove is provided to facilitate the connection of the chuck body seat, so that the overall structure is stable, the waxing operation can be carried out smoothly, and the error is reduced.
[0031] refer to Figure 1-2 As shown, in a further preferred embodiment, the lower clamping base 5 is provided with a first-position lower clamping base 51 and a second-position lower clamping base 52. The first-position lower clamping base 51 and the second-position lower clamping base 52 are fixedly connected. The overall height of the first-position lower clamping base 51 is higher than the height of the second-position lower clamping base 52. The second-position lower clamping base is set on the first-position lower clamping base, which is equivalent to setting up clamping bases in the upper and lower positions, which facilitates the installation, connection and adjustment of the connecting body, and can strengthen the overall connection structure. The waxing device provided in this embodiment is also provided with a control mechanism. The control mechanism is a PLC whole machine control. The PLC whole machine control can be set on the mounting body 1 near the lower clamping mechanism. The PLC whole machine control is electrically connected and signal connected to the above-mentioned drive cylinders.
[0032] Specifically, the process flow of this invention is as follows:
[0033] 1. Turn on the power button on the PLC control interface. The power mechanism on the device will be in a ready-to-work state after the power is connected.
[0034] 2. Place the orthokeratology lens clipping material to be waxed onto the lower chuck body, turn on the wax dispensing device, and perform wax dripping operation on the waxing surface of the clipping material that has been cut into a concave shape on the lathe;
[0035] 3. Turn on the power mechanism start button on the PLC whole machine control operation interface to start the upper chuck body to move downward towards the lower chuck body. When the upper chuck body and the lower chuck body are close together, start the power mechanism down press button to press down the wax layer on the concave surface of the material clamping.
[0036] 4. After the upper chuck body has completed its downward pressing, use the testing equipment to check the wax thickness.
[0037] 5. After the waxed material has been processed, proceed to the next step of lens cutting. After cutting, perform mirror polishing and other processes.
