Description

Technical Field

[0001] This utility model relates to the field of coating frame structure, specifically a lens processing coating frame structure. Background Technology

[0002] A lens coating frame structure is a precision device used to uniformly coat the surface of eyeglass lenses with coating materials. This structure is typically designed with clamps to fix the lens, a rotating mechanism to ensure coating uniformity, and components to connect the coating source, so that the coating material can be deposited onto the lens in a controlled manner in a vacuum or specific gas environment, thereby enhancing the lens performance, such as increasing hardness, scratch resistance, anti-reflection, or changing its optical properties.

[0003] However, current small-scale lens processing coating rack structures primarily rely on manual manipulation of two handles to place the coating rack into the coating machine after the lens is placed on it. During this process, since the lens is positioned within a lens holder, even slight operator error—such as an unstable grip, hand fatigue, or external interference—can easily cause the coating rack to tilt or slip, resulting in the lens falling out of the holder and causing damage or rendering the lens unusable. This instability of manual operation not only increases the risks during lens processing but also affects production efficiency and product quality. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a lens coating frame structure to solve the technical problem that unstable manual operation leads to the coating frame tilting or slipping, which in turn causes lens damage or scrap.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a lens processing coating frame structure, comprising a coating frame, the coating frame comprising an arc-shaped frame body and multiple lens placement slots, each of the multiple lens placement slots having a card slot on its upper part, and each of the multiple card slots having an adsorption mechanism, the adsorption mechanism comprising multiple air extraction holes, the multiple air extraction holes being disposed within the card slots;

[0006] The outer side of the arc-shaped frame is provided with an overlapping ring, and the top of the overlapping ring is provided with an air extraction pipe interface. The air extraction pipe interface is provided with an air passage, and the air passage is connected to multiple air extraction holes.

[0007] By adopting the above technical solution, the lens can be stably fixed in the lens slot by the adsorption mechanism, avoiding the damage that may be caused by traditional mechanical clamping, and improving the stability and precision of lens processing.

[0008] Furthermore, the outer surface of the air extraction pipe interface is provided with external threads, and the air extraction pipe interface is screwed to the external air extraction pipe through the external threads.

[0009] By adopting the above technical solution, the coating rack structure is easy to connect with the external air extraction system, which facilitates the operation and use of the adsorption mechanism, while also ensuring the sealing and stability of the air path.

[0010] Furthermore, a handle is provided at the top of the arc-shaped frame, and the handle includes a handle body.

[0011] By adopting the above technical solution, a handle is provided on the top of the arc-shaped frame, providing operators with a convenient way to carry and operate the equipment.

[0012] Furthermore, the grip is mirror-image arranged along the central axis of the arc-shaped frame, and a rubber sleeve is provided on the grip body.

[0013] By adopting the above technical solutions, the grip is made more stable and durable, and the rubber sleeve provides good anti-slip and shock absorption effects, further improving the safety and comfort of the operator.

[0014] Furthermore, the arc-shaped frame is provided with multiple mirror slots, which are arranged in a circular array at equal intervals.

[0015] By adopting the above technical solution, the coating frame structure can process multiple lenses simultaneously, improving processing efficiency. At the same time, the equidistantly arranged lens slots also ensure the uniformity and consistency of the lenses during the processing.

[0016] Furthermore, a card unloading groove is provided on one side of each of the card slots.

[0017] By adopting the above technical solution, the lens can be easily removed from the lens holder after processing, avoiding the damage and inconvenience that may be caused by traditional lens removal methods. The lens removal slot improves the ease of use and practicality of the coating holder structure.

[0018] In summary, the present invention has the following main advantages:

[0019] This invention features an adsorption mechanism where multiple air extraction holes create negative pressure within the card slot, tightly adsorbing the lens. This physical adsorption method is more stable than traditional mechanical clamping, effectively preventing the lens from moving or slipping during processing, especially when placing the coating rack inside the coating machine or performing other operations. Furthermore, the adsorption mechanism avoids direct contact with the lens surface, reducing scratches or damage caused by improper clamping. This is particularly important for high-precision and high-value lens processing. The stable adsorption effect also ensures the precise position of the lens during the coating process, improving the uniformity and consistency of the coating, thus contributing to improved lens processing accuracy and finished product quality. In addition, the adsorption mechanism simplifies and speeds up the lens loading and unloading process. Operators no longer need complex mechanical devices to clamp the lens; simply placing the lens in the lens holder completes the adsorption work. This not only simplifies the operation process but also improves work efficiency.

[0020] This invention features a handle, with the handle body serving as the main structural component, allowing the operator to maintain a comfortable hand posture and reduce hand fatigue. Simultaneously, the material and structural strength of the handle body ensure that the coating rack can withstand certain external forces and weight during handling or operation, guaranteeing the stability and reliability of the coating rack. Furthermore, the rubber sleeve covering the handle body provides good elasticity and anti-slip properties, increasing friction between the operator's hand and the handle, preventing the coating rack from slipping and falling or being damaged. In addition, the rubber sleeve can absorb and mitigate vibrations and impacts during operation to a certain extent, protecting the operator's hands from injury. Attached Figure Description

[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0027] A lens processing coating frame structure, such as Figures 1-4 As shown, the coating frame 1 includes an arc-shaped frame 101 and multiple mirror slots 103. Each of the multiple mirror slots 103 has a card slot 104 on its upper part, and each of the multiple card slots 104 is provided with an adsorption mechanism 2. The adsorption mechanism 2 includes multiple air extraction holes 202, which are located inside the card slots 104.

[0028] An overlapping ring 102 is provided on the outer side of the arc-shaped frame 101, and an air extraction pipe interface 201 is provided on the top of the overlapping ring 102. The air extraction pipe interface 201 is provided with an air passage, which is connected to multiple air extraction holes 202. This structure, through the design of the arc-shaped frame 101 and multiple lens mounting slots 103, enables the simultaneous processing of multiple lenses, improving production efficiency. The cooperation between the card slot 104 and the adsorption mechanism 2 ensures that the lens is firmly fixed in the lens mounting slot 103, avoiding shaking and displacement during processing and ensuring coating quality. The setting of the air extraction pipe interface 201 and the air passage facilitates the connection between the adsorption mechanism 2 and the external air extraction system, realizing rapid and stable adsorption of the lens.

[0029] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The outer surface of the suction pipe interface 201 is provided with an external thread 203. The suction pipe interface 201 is screwed to the external suction pipe through the external thread 203. The design of the external thread 203 on the outer surface of the suction pipe interface 201 allows the coating frame structure to be easily screwed to the external suction pipe, resulting in a more secure and stable connection. This connection method not only facilitates the use of the adsorption mechanism 2, but also ensures the airtightness of the gas path, avoiding the impact of gas leakage on the coating process.

[0030] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The top of the curved frame 101 is equipped with a handle 3, which includes a handle body 301. The handle 3 on the top of the curved frame 101 provides operators with a convenient way to carry and operate the equipment. The design of the handle body 301 makes the handle more ergonomic, improving the operator's grip comfort and stability, and reducing fatigue during operation.

[0031] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The handle 3 is mirror-shaped along the central axis of the arc-shaped frame 101, and a rubber sleeve 302 is provided on the handle body 301. This mirror-shaped design of the handle 3 along the central axis of the arc-shaped frame 101 makes the coating rack structure more balanced and stable, facilitating handling and operation. The rubber sleeve 302 on the handle body 301 provides good anti-slip and shock absorption effects, further improving operator safety and comfort, and reducing hand slippage and vibration during operation.

[0032] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The arc-shaped frame 101 has multiple lens mounting slots 103 arranged in a circular array at equal intervals. This circular array design allows the coating frame structure to process multiple lenses simultaneously, significantly improving production efficiency. The equally spaced lens mounting slots 103 also ensure the uniformity and consistency of the lenses during processing, improving coating quality.

[0033] See Figure 1 , Figure 2 , Figure 3 , Figure 4 The multiple card slots 104 have a lens removal slot 105 on one side. The lens removal slot 105 on one side of the card slots 104 allows the lens to be easily removed from the lens holder 103 after processing, avoiding the damage and inconvenience that may be caused by traditional lens removal methods. The lens removal slot 105 improves the usability and practicality of the coating holder structure, making the operation more convenient and efficient.

[0034] The implementation principle of this embodiment is as follows: First, the external air extraction pipe and the air extraction pipe interface 201 are tightly screwed together by the external thread 203 to ensure that the air path is unobstructed. The lens to be coated is gently placed into the lens placement slot 103 to ensure that the lens is in close contact with the bottom of the card slot 104. The adsorption mechanism 2 generates negative pressure through multiple air extraction holes 202 to automatically adsorb the lens without the need for additional clamping devices.

[0035] Confirm that the external air extraction pipe is correctly connected to the air extraction pipe interface 201, turn on the air extraction device, and start the adsorption mechanism 2 to further ensure that the lens is stably adsorbed in the lens placement groove 103.

[0036] The operator holds the handle 3 with both hands and uses the comfortable grip provided by the handle body 301 and the rubber sleeve 302 to stably transport the coating rack into the coating machine. During the transport process, the adsorption mechanism 2 continues to work to prevent the lens from falling off due to vibration or collision.

[0037] Place the coating rack in the designated position on the coating machine to ensure the coating process proceeds smoothly. At this point, the air extraction line can be disconnected to avoid affecting the normal processing of the coating machine. When removing the coating rack, reconnect the air extraction line to ensure the stability of the lens when removing it.
