Description

Technical Field

[0001] This utility model relates to the field of lens edging machine technology, specifically to a waterproof cover for an eyeglass lens edging machine with integrated lighting function. Background Technology

[0002] During the processing of eyeglass lens edging machines, a high-speed rotating grinding wheel grinds the edge of the lens while water is sprayed for cooling to reduce dust and heat. Traditional edging machine waterproof covers are mainly used to prevent water splashes and lens powder from flying during the grinding process, but their function is limited and has the following problems:

[0003] Difficulty in observation: The optical performance of the waterproof cover itself (such as light transmittance and anti-fog properties) is usually not optimized. In addition, the natural light in the grinding area is insufficient or the lighting conditions are poor, making it difficult for operators to clearly and in real time observe the grinding status, positioning and wear of the grinding wheel at the edge of the lens. This directly affects the control of processing accuracy and the timely detection of abnormalities.

[0004] Additional lighting requirements: To compensate for insufficient internal lighting, some equipment requires the installation of external lighting fixtures. This not only occupies valuable equipment space and increases wiring complexity and clutter, but also raises installation and maintenance costs. External lights often struggle to accurately and evenly cover the core grinding area, resulting in limited effectiveness.

[0005] Separation of waterproofing and lighting: Even when some equipment incorporates lighting functionality, its lighting components (such as lamps and wiring) are typically installed independently of the waterproof housing or are simply added as an attachment, failing to achieve an integrated, sealed design. This loose structure makes the lighting components highly susceptible to corrosion from the high humidity environment, moisture, and abrasive powder inside, leading to frequent problems such as lamp damage, short circuits, and contamination of light-transmitting windows, thus reducing the overall reliability and lifespan of the system. Utility Model Content

[0006] The purpose of this invention is to address the problem that the waterproof covers for lens edging machines in the prior art have limited functionality, and to provide a waterproof cover for eyeglass lens edging machines with integrated lighting.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: a waterproof cover for a spectacle lens edging machine with integrated lighting function, comprising:

[0008] The main body of the waterproof cover is placed above the grinding wheel and lens grinding station of the edging machine to block water and powder splashes generated during grinding;

[0009] A hollow rotating shaft is disposed on the main body of the waterproof cover;

[0010] A light source is disposed inside the hollow rotating shaft, and the light emission direction of the light source is towards the grinding contact area between the grinding wheel and the lens.

[0011] Furthermore, the light source is an LED light strip, which is embedded in the inner wall of the hollow rotating shaft.

[0012] Furthermore, the power line of the light source passes through the hollow rotating shaft and is connected to the control system of the edge grinding machine.

[0013] Furthermore, the waterproof cover body is detachably connected to the hollow rotating shaft.

[0014] Furthermore, the detachable connection is a snap-fit ​​connection structure.

[0015] Furthermore, the light source strip is disposed on the outer surface of the hollow rotating shaft.

[0016] Furthermore, the light source strip is placed inside the cavity of the hollow rotating shaft.

[0017] Furthermore, the main body of the waterproof cover is made of a transparent or translucent material.

[0018] After adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0019] The light source is directly integrated into the hollow rotating shaft of the waterproof cover, eliminating it from being a separate or simply added component. The light source is embedded within the shaft or closely fitted to its outer surface, requiring no additional space and avoiding the space constraints and messy wiring issues associated with external lighting fixtures. This eliminates the need for external lighting fixture mounting brackets and separate power cords, resulting in a cleaner overall appearance and higher internal space utilization.

[0020] The power cord is routed inside the hollow rotating shaft, facilitating a good seal at the shaft end (e.g., using waterproof connectors or sealing rings), effectively preventing water droplets, moisture, and grinding powder from corroding the wiring and light source. Compared to standalone luminaires and exposed wiring, the integrated design significantly reduces the number of easily contaminated exposed surfaces. The light source (especially recessed ones) and wiring are well protected, significantly reducing the risk of malfunctions such as luminaire damage, short circuits, and blurred light transmission windows caused by moisture condensation and dust adhesion.

[0023] Figure 2 yes Figure 1 A sectional view along line AA.

[0024] Explanation of reference numerals in the attached drawings: 1. Waterproof cover body; 2. Hollow rotating shaft; 3. Light source. Detailed Implementation

[0025] See Figures 1-2 As shown, the technical solution adopted in this specific embodiment is: a waterproof cover for a spectacle lens edging machine with integrated lighting function, comprising:

[0026] An arched or hemispherical waterproof cover body 1 made of transparent or semi-transparent material is placed above the grinding wheel and lens grinding station of the edging machine to block water splashes and powder splashes generated during grinding.

[0027] A hollow rotating shaft 2 is mounted on the waterproof cover body 1 and its two ends are installed on the edge grinding machine bracket through ball bearings to achieve rotation.

[0028] Light source 3 is a light strip, which is embedded in the inner wall of the hollow rotating shaft 2. The light emission direction of the light source 3 is towards the grinding contact area between the grinding wheel and the lens. The power line of the light source 3 passes through the hollow rotating shaft 2 and is connected to the control system of the edge grinding machine.

[0029] In another embodiment, the waterproof cover body 1 is detachably connected to the hollow rotating shaft 2 via a snap-fit ​​connection structure.

[0030] In another embodiment, the light source 3 is a light strip, which is placed on the outer surface of the hollow rotating shaft 2.

[0031] The working principle of this utility model:

[0032] 1. Start-up preparation:

[0033] The operator clamps the eyeglass lenses to be processed onto the fixture of the edging machine.

[0034] The edge grinding machine control system is activated. At this time, the light source 3 (usually a light strip) integrated in the hollow rotating shaft 2 of the waterproof cover is also synchronously powered on and lit.

[0035] The light emitted by the light source 3 shines directly and concentratedly onto the grinding area where the grinding wheel and the lens are about to come into contact / are in contact, through the transparent / semi-transparent waterproof cover body 1 (or a specially designed observation window).

[0036] 2. Grinding process:

[0037] The main motor of the edge grinding machine starts, driving the grinding wheel to rotate at high speed.

[0038] Under program control, the lens clamp precisely pushes the lens edge towards a high-speed rotating grinding wheel for grinding, following a preset lens shape and size path.

[0039] The cooling system is activated, continuously spraying water into the grinding contact area to cool the grinding wheel and lens, and reduce dust emissions.

[0040] The main body of the waterproof cover 1 (installed above the grinding wheel and lens grinding station) plays a core protective role:

[0041] Splash prevention: Effectively prevents water droplets, coolant mist, and fine glass / resin powder generated during high-speed grinding from splashing outwards, protecting other parts of the equipment and the operating environment.

[0042] Contains contaminants: Water and powder are contained within the waterproof enclosure, facilitating subsequent collection and treatment via the equipment's drainage / vacuum system.

[0043] 3. Core lighting operation:

[0044] Continuous illumination: The light source strip located inside the hollow rotating shaft 2 (or embedded in the inner wall or wrapped around the outer surface) emits light continuously.

[0045] Precise targeting: The installation position and light emission direction of the light source are designed to ensure that the light is focused directly and unobstructed on the grinding point where the grinding wheel and the lens actually come into contact.

[0046] Uniform coverage: LED strips (especially spiral or long embedded strips) can provide bright, uniform lighting that surrounds or covers a large area, effectively eliminating shadows in the grinding area.

[0047] Water mist penetration: The high-brightness light source can effectively penetrate the water mist and splashes generated in the grinding area, providing operators with a clear view.

[0048] 4. Real-time observation and monitoring:

[0049] Through the transparent / semi-transparent waterproof cover body 1, under bright and uniform integrated light source illumination, the operator can:

[0050] Clearly observe the real-time state of the lens edge being ground by the grinding wheel (grinding amount, whether the edge shape meets the standard, whether there are defects such as chipping).

[0051] Confirm that the lens is accurately positioned on the fixture and moves along the predetermined path.

[0052] Check the wear of the grinding wheel's working surface (such as whether it is dulled or chipped) to determine whether the grinding wheel needs to be replaced or overhauled.

[0053] Promptly detect any abnormalities that may occur during the grinding process (such as loose lens, abnormal vibration of the grinding wheel, insufficient cooling water, etc.).

[0054] 5. Process complete:

[0055] Once the lens edge grinding is complete, the edging machine program stops.

[0056] The grinding wheel stops rotating, and the lens clamp is removed.

[0057] Cooling water shut off.

[0058] The operator opens the waterproof cover and removes the processed lens.

[0059] 6. Maintenance (periodic or as needed):

[0060] Since the waterproof cover body 1 and the hollow rotating shaft 2 with light source 3 are usually connected in a detachable manner (such as by a buckle):

[0061] Operators can easily remove the entire waterproof cover assembly (or the rotating shaft section).

[0062] If light source 3 is damaged, the light strip module can be disassembled and replaced relatively easily.

[0063] After replacement, the components can be quickly and reliably reinstalled in their original positions using clips or other means.

[0064] The above description is only used to illustrate the technical solution of this utility model and is not intended to limit it. Any other modifications or equivalent substitutions made by those skilled in the art to the technical solution of this utility model, as long as they do not depart from the spirit and scope of the technical solution of this utility model, should be covered within the scope of the claims of this utility model.
