Description

Technical Field

[0001] This application belongs to the field of lens measurement technology, specifically relating to a measuring device for 3D watch lenses. Background Technology

[0002] In the watchmaking industry, the importance of lens contour measurement is becoming increasingly prominent. As a key component, the precision of the lens contour directly determines the fit of subsequent assembly processes. Even slight contour deviations can lead to assembly misalignment, compromising the overall structural stability of the watch. Simultaneously, contour is also a core factor affecting the watch's water resistance. If the contour fails to meet standards, the watch will struggle to pass water tightness tests, significantly reducing the product's durability and user experience. With intensifying industry competition and ever-increasing customer demands for product quality, strictly controlling the accuracy of lens contour measurement has become a crucial step in ensuring product quality and enhancing market competitiveness, and is an industry consensus that watch manufacturers must adhere to.

[0003] Currently, the mainstream method for detecting the contour of 3D watch lenses in the industry is the probe-based contact measurement method. This technology collects data from the lens surface point by point, and then fits the contour curve after coordinate system transformation. In actual operation, due to the complex three-dimensional curved surface structure of the lens, the measurement process needs to be divided into two independent stages: front contour data acquisition and back contour data acquisition. Furthermore, the lens must be flipped over. This method requires multiple clamping and positioning operations, making the process complex and significantly reducing detection efficiency. Utility Model Content

[0004] To address the shortcomings of the prior art, this application provides a measuring device for 3D watch lenses, which has the advantages of simplifying measurement operations and improving measurement efficiency.

[0005] The technical effects to be achieved in this application are realized through the following aspects:

[0006] This application provides a measuring device for 3D watch lenses, including a support component, which includes a plurality of evenly spaced support members, and the support members are provided with airflow adsorption grooves;

[0007] Several of the aforementioned support members are provided with an adsorption end and an air supply end opposite to each other. The adsorption end is used to support the 3D watch lens, and the air supply end is used to connect the air source and the airflow adsorption groove to create a negative pressure adsorption surface at the adsorption end.

[0008] The adjacent support members form a detection area, which is used for probes to extend into in order to detect the convex part of the 3D watch lens.

[0009] In some implementations, one end of the support member is inclined toward the central axis of the support component, and the plane formed by the adsorption end is adapted to the convex part of the 3D watch lens.

[0010] In some implementations, the support component further includes a limiting member surrounding the side of the support component near the gas supply end.

[0011] In some implementations, the support component further includes a venting element connected to the air supply end, the venting element having an air cavity inside, and the air cavity communicating with a plurality of the airflow adsorption grooves;

[0012] The vent is provided with an air inlet on one side, and the air inlet communicates with the air chamber.

[0013] In some implementations, an auxiliary positioning element is also included to help the 3D watch lens be centered on the adsorption end.

[0014] In some implementations, the auxiliary positioning member has a through hole, which is movably fitted onto the support member.

[0015] In some implementations, the auxiliary positioning component is provided with a placement groove located at the edge of the through hole for placing a 3D watch lens.

[0016] In some implementations, the bottom of the placement groove is inclined toward the central axis of the through hole, and the bottom of the placement groove is adapted to the convex part of the 3D watch lens.

[0017] In some implementations, the number of support members is 6-10.

[0018] In some implementations, the venting element includes a body and a sealing plate, the sealing plate being sealed to the end of the body away from the support.

[0019] In summary, this application has at least the following advantages:

[0020] The measuring device for 3D watch lenses provided in this application uses spaced support members to create a negative pressure adsorption surface to stably fix the lens, while forming a detection area between adjacent support members for probes to extend into. This solves the problem of having to flip the lens during traditional lens measurement. This solution allows the 3D watch lens to be fixed once and measured directly on both sides without having to flip it again, effectively simplifying the measurement process and improving detection efficiency.

[0028] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0029] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0030] Example 1:

[0031] Please see the appendix Figure 1-2 The measuring device of this application for 3D watch lens includes a support component 1, which includes a plurality of evenly spaced support members 11. Each support member 11 is provided with an airflow adsorption groove 111. The plurality of support members 11 are provided with an adsorption end 12 and an air supply end 13 opposite to each other. The adsorption end 12 is used to support the 3D watch lens 3, and the air supply end 13 is used to connect the air source and the airflow adsorption groove 111 to form a negative pressure adsorption surface at the adsorption end 12. A detection area 14 is formed between adjacent support members 11. The detection area 14 is used for probes to be inserted to detect the convex part of the 3D watch lens 3.

[0032] Specifically, several support components 11 can be arranged in a ring array to form a stable positioning reference through multi-point support. The adsorption end 12 refers to the part of the support component 11 that contacts the lens. The air supply end 13 refers to the part of the support component 11 that connects to the air source.

[0033] In this embodiment, the measuring device uses support members 11 arranged in an array to form a ring-shaped support structure. Each support member 11 has an internal airflow adsorption groove 111 that creates a negative pressure environment after being connected to an external air source at the air supply end 13. When the lens is placed at the adsorption end 12, the negative pressure airflow acts uniformly on the lens surface through the adsorption groove, forming a multi-point distributed adsorption fixation. The regular gaps between adjacent support members 11 form a probe movement channel, allowing the probe to pass through the gaps vertically to contact the front and back surfaces of the lens. During a single clamping process, the probe can successively enter different detection areas 14 to collect contour data of the convex and concave surfaces of the lens. The spaced arrangement of the support members 11 ensures both uniform distribution of adsorption force and avoids interference with the probe's movement path.

[0034] This solution combines a distributed support structure with negative pressure adsorption to maintain stable lens positioning while preserving the detection channel. This allows the probe to directly contact both sides of the lens to complete data acquisition, enabling double-sided detection in a single clamping operation. This avoids the flipping operation required in traditional measurements, eliminating the cumbersome procedures and positioning errors associated with it. The structural design allows front and back contour data to be acquired in the same coordinate system, improving measurement data consistency and reducing manual intervention, thus significantly increasing detection efficiency.

[0035] In some embodiments, one end of the support member 11 is inclined toward the central axis of the support member 1, and the plane formed by the adsorption end 12 is adapted to the convex part of the 3D watch lens 3.

[0036] Specifically, when the support members 11 converge toward the central axis at a preset tilt angle, the adsorption ends 12 of each support member 11 form a spherical distribution in space. During lens placement, when the convex part of the lens contacts the adsorption end 12, the curved surface of the adsorption end 12 makes multi-point contact with the curved surface of the lens. After the negative pressure adsorption is activated, the lenses are all adsorbed and fixed by the airflow in the airflow adsorption groove 111. This structure enables the lenses to achieve stable positioning through the dual effects of geometric constraints and airflow adsorption without the intervention of an additional positioning mechanism.

[0037] The spatial layout design of the inclined support 11 ensures that the convex surface of the lens and the adsorption end 12 form a surface contact, reducing local pressure and preventing indentations on the lens surface; the geometric adaptation eliminates the initial positional deviation when the lens is placed, so that the probe detection reference surface and the actual curved surface of the lens maintain spatial consistency; the mechanical properties of the inclined support 11 are used to effectively bear the weight of the lens, improving the reliability and stability of the lens placement.

[0038] In some embodiments, the number of supports 11 is 6-10. Preferably, 6 supports 11 can be used. This number range ensures adsorption stability while avoiding the situation where the spacing between adjacent supports 11 is too small, which would prevent the probe from being able to extend into the detection area 14.

[0039] Specifically, when the number of supports 11 is set to 6-10, the evenly distributed supports 11 form a ring array structure. The airflow adsorption groove 111 of each support 11 generates negative pressure adsorption force, which works together on the curved surface of the lens. The spacing between adjacent supports 11 is adjusted according to the total number, providing sufficient operating space for probe detection while ensuring the stability of the lens. This number range prevents insufficient adsorption force due to too few supports 11, and also avoids excessive occupation of the detection area 14 by the supports 11, enabling multi-directional detection to be completed in a single clamping. Through this setting, not only is the placement stability of the 3D watch lens 3 guaranteed, but also the continuous and smooth measurement of both sides of the lens is ensured.

[0040] Example 2:

[0041] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 3 The support component 1 in this embodiment also includes a limiting component 15, which surrounds the side of the support component 11 near the air supply end 13.

[0042] In this embodiment, when the gas source delivers airflow to the airflow adsorption tank 111 through the gas supply end 13, the annular structure of the limiting member 15 forms a radial constraint on the support member 11, preventing it from shifting laterally due to airflow pressure fluctuations. For example, when the pressure in the gas supply pipeline suddenly increases, the support member 11 may shift outward due to the gas pressure reaction force. At this time, the inner wall surface of the limiting member 15 contacts the outer surface of the support member 11, and the displacement tendency is counteracted by friction and structural reaction force. This maintains the sealed connection between the gas supply end 13 and the gas source interface, avoids airflow leakage due to misalignment of the support member 11, and ensures that the pressure value of the negative pressure adsorption surface remains stable within the set range.

[0043] This solution, by adding a ring-shaped limiting component 15, establishes a rigid constraint at the air supply end 13 of the support component 11, where displacement is most likely to occur. This effectively prevents displacement of the support component 11 during the air supply process, ensuring stable communication between the air source and the airflow adsorption tank 111, and ensuring that the negative pressure adsorption surface continuously generates uniform adsorption force. This avoids repeated positioning operations caused by displacement of the support component 11, allowing the probe to accurately extend into the detection area 14 to complete the surface measurement, significantly improving detection efficiency and data acquisition consistency.

[0044] In some embodiments, the support component 1 further includes a vent 16, which is connected to the air supply end 13. The vent 16 has an air chamber 161 inside, which is connected to a plurality of airflow adsorption grooves 111. An air inlet 162 is provided on one side of the vent 16, which is connected to the air chamber 161.

[0045] Specifically, an external air source injects gas into the air chamber 161 through the air inlet 162. The volumetric characteristics of the air chamber 161 allow the airflow pressure to reach a dynamic equilibrium within the chamber, and then the gas is evenly distributed to each support member 11 through the connected airflow adsorption groove 111. Due to the buffering effect of the air chamber 161, even if the external air source pressure fluctuates, the adsorption ends 12 of each support member 11 can still maintain a balanced negative pressure adsorption force. By achieving single-point air supply and multi-point balanced distribution through the integrated ventilation component 16, not only is the air circuit system structure simplified and equipment maintenance costs reduced, but the pressure stabilizing characteristics of the air chamber 161 also eliminate pressure differences between the adsorption ends 12, ensuring that the lens is always under uniform force during the detection process. This ensures that the lens does not shift or vibrate during the detection process, providing a stable reference positioning for probe detection.

[0046] In some embodiments, the vent 16 includes a body 163 and a sealing plate 164, the sealing plate 164 being sealed to the end of the body 163 away from the support member 11. Specifically, the separate structure of the body 163 and the sealing plate 164 allows the sealing plate 164 to be disassembled separately for cleaning of the air chamber 161 or repair of the sealing surface during maintenance, without having to replace the entire vent 16, thus achieving removable maintenance while ensuring the air chamber 161 is airtight.

[0047] Example 3:

[0048] The difference between this embodiment and Embodiment 1 is that, please refer to... Figure 4 The measuring device in this embodiment also includes an auxiliary positioning component 2, which is used to help the 3D watch lens 3 be centered on the adsorption end 12.

[0049] In this embodiment, the measuring device uses an auxiliary positioning member 2 that forms a surface contact with the convex surface of the lens through the curved constraint of the placement groove 22, providing guidance during lens placement. When the operator places the lens into the placement groove 22, the inclined bottom of the groove guides the lens to slide in a specific direction until the edge of the lens contacts the groove wall, at which point the central axis of the lens coincides with the central axis of the support member 1. This process eliminates the need for manual visual calibration, removing positioning errors caused by visual deviations, and allowing the lens to reach the required reference position for testing in one go.

[0050] In some embodiments, see Figure 5The auxiliary positioning component 2 has a through hole 21, which is movably fitted onto the support component 1. The auxiliary positioning component 2 also has a placement groove 22 located at the edge of the through hole 21 for placing the 3D watch lens 3. The through hole 21 is a circular channel penetrating the auxiliary positioning component 2, which can be implemented using a hole structure with an inner diameter slightly larger than the outer diameter of the support component 1, allowing the auxiliary positioning component 2 to slide axially along the support component 1. The depth of the placement groove 22 matches the thickness of the lens, and by adapting its geometric shape to the edge contour of the lens, it achieves horizontal constraint on the lens.

[0051] Specifically, the operation process of measuring the lens is as follows: First, the 3D watch lens 3 is placed in the placement slot 22. Then, the auxiliary positioning component 2 is moved to the support component 1. When the through hole 21 is aligned with the support component 1, the auxiliary positioning component 2 is driven to descend smoothly, and the support component 1 is inserted into the through hole 21. This achieves the alignment of the central axis of the auxiliary positioning component 2 and the central axis of the support component 1 until the 3D watch lens 3 contacts the adsorption end 12. At this point, the air source is activated, allowing the adsorption end 12 to stably adsorb the 3D watch lens 3, thus quickly completing the placement of the 3D watch lens 3. Finally, the measurement program is started. The device probe begins to work, sequentially measuring the concave surface points of the product, and then extending the probe from the side of the base to sequentially measure the convex surface points of the product.

[0052] With the above settings, positioning can be completed without manual adjustment of the lens angle. The lens only needs to be placed once during the inspection process to achieve axial and circumferential positioning, avoiding repeated calibration operations caused by lens offset during traditional clamping. The inspection preparation time is greatly shortened, the continuity of the inspection process is guaranteed, and the overall inspection efficiency is effectively improved.

[0053] In some embodiments, the bottom of the placement groove 22 is inclined toward the central axis of the through hole 21, and the bottom of the placement groove 22 is adapted to the convex part of the 3D watch lens 3.

[0054] Specifically, when the lens is placed in the placement slot 22, the inclined bottom guides the lens to slide along the inclined direction to the central axis area of ​​the through hole 21, completing the initial positioning; at the same time, the bottom curved surface fully fits the convex surface of the lens, allowing the lens to automatically complete precise positioning in a natural placement state. In this process, the lens only needs to be placed once to achieve both axial positioning and horizontal limiting, without the need for manual adjustment. This effectively reduces the time spent on repeated positioning operations and improves testing efficiency.
