[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] The following is combined Figures 1-6 This invention describes a card core comprising a base portion 1 and a plurality of clamping pieces 2 connected to the base portion 1. The clamping pieces 2 are evenly arranged circumferentially, and the enclosed area of ​​the clamping pieces 2 forms a clamping space 3 for clamping a tooling. The card core also includes an auxiliary force-applying member connected to the clamping pieces 2, which applies a uniform force to each clamping piece 2 to assist in clamping the tooling placed in the clamping space 3. The base portion 1 is a cylindrical annular shape, and the plurality of clamping pieces 2 are disposed at one end of the axial direction of the base portion 1 and are evenly arranged circumferentially. The base portion 1 can be integrally formed with the plurality of clamping pieces 2, or it can be formed in a later processing step.

[0026] In this invention, by setting an auxiliary force-applying component on the basis of the existing card core, the force applied by the auxiliary force-applying component to the clamping plate 2 is used to provide assistance when clamping the tooling, so that the tooling is no longer clamped solely by the tension of the clamping plate 2 itself, thereby effectively extending the service life while ensuring the product processing quality.

[0027] In related technologies, the lens core includes multiple clamping tabs 2 evenly arranged circumferentially. The area enclosed by the multiple clamping tabs 2 forms a clamping space 3, with a gap 4 between adjacent clamping tabs 2. During use, a fixture is inserted into the clamping space 3 between the clamping tabs 2, and the fixture is clamped by the tension of the clamping tabs 2 themselves. As production capacity increases, the lens core may loosen after processing a certain number of units, causing the clamping tabs 2 on one side of the lens core to fail to clamp the fixture tightly. This results in off-center or even edge defects in the finished lens after inspection, necessitating the scrapping of the lens core, which has a short service life. Currently, the lens core is made of iron. After the fixture is inserted into the clamping space 3 of the lens core, it is necessary to observe and confirm whether the gaps 4 are consistent. If the gaps 4 are neither too narrow nor too wide, it proves that the mechanical centers of the fixture, lens core, and product are on the same straight line, thus ensuring the accuracy of lens processing. If the gaps 4 are too wide or too narrow, it proves that the mechanical centers of the lens core, fixture, and product are not on the same straight line, resulting in off-center defects in the finished product after inspection. In severe cases, this can lead to defective product edges, affecting the product pass rate. The only solution is to replace the card core, resulting in a shorter lifespan for the card core.

[0028] In this invention, by adding an auxiliary force-applying component to the original card core, the auxiliary force-applying component applies a force to the clamping plate 2. This force can be used to assist in clamping the tooling, and the force applied to the clamping plate 2 is uniform. This means that when the card core clamps and fixes the tooling, it no longer relies solely on the tension of the clamping plate 2 itself, thereby reducing the possibility of structural deformation of the clamping plate 2. While ensuring the quality of product processing, this effectively extends the service life of the card core.

[0029] Specifically, the card core of this utility model is used to clamp and fix the tooling. The tooling is used to connect the lens. The lens has AB sides. The tooling connects to the A side of the lens. After applying wax, the B side of the lens is processed.

[0030] like Figure 1 and 2 As shown, in some embodiments, a gap 4 is formed between two adjacent clamping pieces 2, and the auxiliary force-applying member is an elastic member 5 disposed in the gap 4. The elastic member 5 applies an equal and opposite elastic force to the clamping pieces 2 on both sides.

[0031] In this invention, a gap 4 is formed between two adjacent clamping pieces 2, allowing the tension of the clamping pieces 2 to clamp and fix the tooling in the clamping space 3. An elastic element 5 is provided within the gap 4, and the elastic force exerted by the elastic element 5 on both clamping pieces 2 is equal in magnitude and opposite in direction, meaning the elastic force exerted by the elastic element 5 on both clamping pieces 2 is uniform. When the tooling is inserted into the clamping space 3, clamping is no longer solely dependent on the clamping pieces 2; the elastic force exerted by the elastic element 5 on the clamping pieces 2 also helps the clamping pieces 2 return to their original shape. This allows the elastic force exerted by the elastic element 5 on the clamping pieces 2 to be converted into a clamping force, ensuring concentricity of the clamping and fixing of the tooling and preventing eccentricity problems during product processing and inspection. Simultaneously, by reducing the deformation of the clamping pieces 2, the service life of the clamping core is extended.

[0032] In some embodiments, elastic members 5 are respectively provided in the multiple gaps 4 of the card core to keep the width of the multiple gaps 4 consistent.

[0033] In this invention, the card core has multiple cards evenly arranged circumferentially, with a gap 4 between each pair of adjacent cards. The gap 4 is arranged radially along the card core. After the tooling is inserted into the clamping space 3, the tooling applies a radially outward pushing force to the surrounding cards, while the cards exert a radially inward clamping force on the tooling, thereby achieving clamping and fixing of the tooling. By providing elastic elements 5 in each gap 4, and ensuring that the elastic force applied by the elastic elements 5 to the clamping pieces 2 is equal, the tension between each clamping piece 2 is ensured to be the same, thus guaranteeing the concentricity of the card core when clamping and fixing the tooling.

[0034] like Figure 3 As shown, further, the clamping piece 2 is provided with a receiving groove 21 on the side facing the gap 4, and the two ends of the elastic member 5 are respectively provided in the two receiving grooves 21 that are arranged opposite to each other.

[0035] In this utility model, since the gap 4 between two adjacent clamping pieces 2 is very small, a receiving groove 21 is provided on the side of the clamping piece 2 facing the gap 4 to specifically accommodate the elastic element 5. The two adjacent clamping pieces 2 are provided with receiving grooves 21 on the side facing the gap 4. The two ends of the elastic element 5 are respectively located in the two receiving grooves 21 and abut against the two clamping pieces 2 respectively. This ensures that after the elastic element 5 applies elastic force to the clamping pieces 2 on both sides, the tension of the two clamping pieces 2 is the same, thereby ensuring the consistency of the gap 4 after the tooling is installed.

[0036] Specifically, by setting the receiving groove 21, the elastic element 5 can be effectively fixed, preventing it from falling out of the gap 4. Furthermore, a larger volume and greater elastic force of the elastic element 5 can be selected, ensuring the accuracy of its position and thus guaranteeing the consistency of the elastic force applied to the clamping plates 2 on both sides. When inserting the elastic element 5 into the receiving groove 21, it can be compressed before insertion.

[0037] like Figure 3 As shown, in some embodiments, the clip 2 is provided with a pick-and-place opening 22 that communicates with the receiving groove 21 for picking up and placing the elastic member 5. The size of the pick-and-place opening 22 is smaller than the size of the elastic member 5.

[0038] In this invention, the placement port 22 facilitates the placement and removal of the elastic element 5. The size of the placement port 22 is smaller than the size of the elastic element 5 in its normal state, i.e., smaller than the size of the elastic element 5 when not subjected to external force, effectively preventing the elastic element 5 from falling out through the placement port 22. When inserting the elastic element 5 into the receiving groove 21, the elastic element 5 is first compressed to a size smaller than the placement port 22, and then inserted into the receiving groove 21 through the placement port 22. After being positioned correctly, the elastic element 5 returns to its original shape under its own elastic force, thus completing the insertion of the elastic element 5. When removing the elastic element 5 from the receiving groove 21, it can be compressed with the aid of a tool, and then removed through the placement port 22. The placement port 22 is not only used for placing and removing the elastic element 5, but also for inspecting the elastic element 5 to check whether its position in the receiving groove 21 is accurate.

[0039] In related technologies, after a certain number of uses, the tension of the clip 2 in existing card cores becomes inconsistent due to deformation caused by repeated pressure, requiring the replacement of the entire card core. However, in this invention, by providing an elastic element 5 within the gap 4 of the clip 2, when inconsistent tension occurs, the elastic element 5 can be replaced entirely or partially; generally, complete replacement is preferred, restoring the tension of the clip 2 to its original state and thus extending the service life of the card core.

[0040] Specifically, the loading and unloading port 22 can be located on the outer surface of the clip 2 or on the inner surface of the clip 2.

[0041] In some embodiments, the elastic element 5 is any one of a spring 51, a rubber element 52, and a hydraulic spring.

[0042] like Figure 3 As shown, in a specific embodiment, the elastic element 5 is a spring 51. After the spring 51 is compressed, it is placed into the receiving groove 21 through the take-out port 22. The two ends of the spring 51 abut against the clamps 2 on both sides, thereby applying a uniform elastic force to the clamps 2 on both sides.

[0043] like Figure 4 As shown, in another specific embodiment, the elastic element 5 is a rubber element 52, which is a solid rubber ball. After the rubber element 52 is compressed, it is placed into the receiving groove 21 through the take-out port 22. The two ends of the rubber element 52 abut against the clamping pieces 2 on both sides, thereby applying a uniform elastic force to the clamping pieces 2 on both sides.

[0044] In another specific embodiment, the elastic element 5 is a hydraulic spring 51. After the hydraulic spring 51 is compressed to a certain volume, it is inserted into the receiving groove 21 through the take-out port 22. The two ends of the hydraulic spring 51 abut against the clamping pieces 2 on both sides, thereby applying a uniform elastic force to the clamping pieces 2 on both sides.

[0045] It is clear that the elastic element 5 is not limited to spring 51, rubber element 52 and hydraulic spring 51, but can also be other elastic structures, such as spring sheet, hydraulic push rod, etc., which are not limited here.

[0046] In some embodiments, the auxiliary force application component includes: a power unit 6 disposed on the clamping plate 2, the power unit 6 having a movable end that can move radially along the core; and a chuck 7 disposed on the movable end of the power unit 6, the chuck 7 being located within the clamping space 3.

[0047] like Figures 5-6 As shown, in this utility model, the auxiliary force-applying component may further include a power unit 6 and a chuck 7. The power unit 6 drives the chuck 7 within the clamping space 3 to move radially along the clamping space 3, and the chuck 7 clamps the tooling in the clamping space 3. The clamping and fixing of the tooling is completed by multiple chucks 7. At this time, the clamping piece 2 indirectly applies clamping force to the tooling as a bearing part, without having to consider the reduction of the tension of the clamping piece 2 material, which can effectively improve the service life of the card core.

[0048] Specifically, multiple chucks 7 are evenly arranged circumferentially within the clamping space 3, and the chucks 7 can move radially along the clamping space 3. By moving the chucks 7 toward the center of the clamping space 3, the tooling is clamped and fixed. By moving the chucks 7 toward the clamping plate 2, the clamping and fixing of the tooling is released. An arc-shaped structure is provided on the side of the chucks 7 facing the tooling. The arc-shaped structure can better fit the outer circumferential surface of the tooling, ensuring the clamping effect of the tooling.

[0049] Furthermore, the power unit 6 drives the chuck 7 to move radially along the clamping space 3 to clamp the tooling, thereby achieving active control of the clamping force. The clamping force is adjustable to adapt to tooling of different specifications.

[0050] Because the tooling is clamped and fixed by the cooperation of the power unit 6 and the chuck 7, multiple clamping pieces 2 can be set into a single unit. That is, there is no need to set a gap 4 between two adjacent clamping pieces 2. Multiple clamping pieces 2 form a ring, which can further improve the structural strength of the clamping piece 2 and further extend the service life of the card core.

[0051] Furthermore, multiple auxiliary force-applying components are evenly arranged circumferentially, and each auxiliary force-applying component corresponds to a clamp 2.

[0052] In this invention, by setting multiple auxiliary force-applying components, which are evenly arranged along the circumference of the card core, the chucks 7 of the multiple auxiliary force-applying components can clamp and fix the tooling in the clamping space 3 from all sides, thereby ensuring the uniformity of the clamping force on the tooling, avoiding the tooling from being eccentric, ensuring the uniform distribution of clamping force, improving system stability, and enhancing control accuracy.

[0053] In some embodiments, the power unit 6 is a cylinder, and the air inlets of multiple cylinders are connected to the same external air source.

[0054] In this invention, multiple cylinders are connected to the same external air source to ensure that the pressure of the multiple cylinders is consistent, thereby ensuring that the clamping force applied by the multiple chucks 7 to the tooling is equal, simplifying the control system and reducing costs.

[0055] This card core incorporates an auxiliary force-applying component on top of the existing card core. The force applied by the auxiliary force-applying component to the clamping plate 2 is used to assist in clamping the tooling, instead of relying solely on the tension of the clamping plate 2 itself to clamp the tooling. This effectively extends the service life while ensuring product processing quality.

[0056] The following table compares the experimental data of the modified card core of this utility model with that of the existing card core:

[0064] Table 4

[0065]

[0066] Data comparison shows that:

[0067] Table 1 shows that the existing cartridge cores began to exhibit eccentricity when processing 801-1000 lenses. After processing 1400 lenses, 10 lenses were found to be eccentric and 5 lenses had incomplete edges. Upon inspection, it was discovered that the gap on one side was relatively wider than the other gaps, and the cartridge core was slightly loose when clamped to the fixture, resulting in some defective lenses. The cartridge cores need to be corrected before continued use.

[0068] Table 2 shows that eccentricity appeared when 1200 rubber core pieces were processed. After processing 1400 pieces, two pieces were eccentric and one piece had an incomplete edge. Upon inspection, it was found that a rubber ball had detached. The core can be reused by installing a new rubber ball.

[0069] Table 3 shows that when 1400 spring clips were processed, there was no eccentricity. Upon inspection, the springs were not missing, the gap width was relatively consistent, and the elastic force was relatively even, which was able to clamp the tooling without any signs of shaking.

[0070] Table 4 shows that after processing 1600 cylinder chucks, no eccentricity was observed, the chuck dimensions did not deform due to use, and no defects were found on the product edges. This design is a pneumatic three-clamp chuck, which eliminates the need to consider tension reduction in the clamping material, effectively improving the chuck's service life.

[0071] This utility model relates to a wax-adhesive machine, which includes the aforementioned card core.

[0072] In this utility model, the waxing machine uses the aforementioned card core. The base part 1 of the card core is installed into the card slot of the waxing machine, and then the tooling is clamped and fixed through the clamping space 3 of the card core. The tooling is used to connect the lens, ensuring that the mechanical center of the lens, tooling and card core are on the same straight line, improving the overall performance of the machine, expanding the application range and improving product quality.
