Description

Technical Field

[0001] This utility model relates to the technical field of shock-absorbing washers, and in particular to a biomimetic washer and laser processing equipment. Background Technology

[0002] Laser processing equipment is a high-precision processing equipment that can be widely used in various processing processes such as marking, cutting, and welding.

[0003] Meanwhile, the factors affecting further improvement in processing accuracy and their proportions have also changed, among which vibration has a significant impact on precision laser processing.

[0004] Therefore, laser processing equipment is often equipped with rubber pads or rubber rings to achieve vibration reduction.

[0005] However, for ordinary rubber pads, after installation, there will be a large stress inside the rubber pad, which will accelerate the aging of the rubber pad and make it very easy to fail due to fatigue. Utility Model Content

[0006] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a biomimetic washer that can reduce internal stress during installation, delay aging, reduce the probability of fatigue failure, and improve the service life of the washer, thus meeting the needs of precision laser processing.

[0007] This invention also proposes a laser processing device having the aforementioned biomimetic gasket.

[0008] According to a first aspect of the present invention, the bionic washer includes a first washer body and a second washer body, wherein the first washer body and the second washer body are stacked one on top of the other.

[0009] One of the first pad and the second pad includes a recess, and the other of the first pad and the second pad includes an arch.

[0010] The middle portion of the recessed portion and the middle portion of the arched portion abut each other or are integrally formed, or the edge of the recessed portion and the edge of the arched portion abut each other or are integrally formed.

[0011] The biomimetic gasket according to the embodiments of this utility model has at least the following beneficial effects: By providing a first gasket and a second gasket, one of which includes a recessed portion and the other includes an arched portion, the middle portions of the recessed portion and the middle portions of the arched portion abut or are integrally formed, or the edges of the recessed portion and the edges of the arched portion abut or are integrally formed. This structure allows the stress to be distributed more evenly when the gasket is subjected to pressure, avoiding the problem of stress concentration inside ordinary rubber gaskets, thereby reducing the stress level inside the gasket and extending its service life. Due to the reduction of internal stress, the elastic properties of the gasket are better maintained, enabling it to more effectively absorb and buffer vibrations generated by laser processing equipment, reducing the impact of vibrations on the equipment, and improving the accuracy and quality of laser processing. Furthermore, the integrally formed structure enhances the overall strength and stability of the gasket, making it less prone to deformation and damage during long-term use, ensuring the durability of the shock absorption effect.

[0012] According to some embodiments of the present invention, the first pad includes the recessed portion, the second pad includes the arched portion, and the middle portion of the recessed portion and the middle portion of the arched portion are integrally formed.

[0013] According to some embodiments of the present invention, the middle portion of the recessed portion and the middle portion of the arched portion are connected through each other, and the inner edge of the recessed portion and the inner edge of the arched portion are integrally formed.

[0014] According to some embodiments of the present invention, the radial connection length L3 between the recess and the arch is 1 / 4 to 1 / 3 of the bending arc length L2 of the arch.

[0015] According to some embodiments of the present invention, the radial connection length L3 between the recessed portion and the arched portion is 1 / 4 of the bending arc length L2 of the arched portion.

[0016] According to some embodiments of the present invention, the bending arc length L1 of the recessed portion is less than or equal to the bending arc length L2 of the arched portion.

[0018] According to some embodiments of the present invention, one of the first pad and the second pad includes an outwardly protruding edge, the inner side of which is used to accommodate the other of the first pad and the second pad.

[0019] According to some embodiments of the present invention, the height h2 of the outer convex edge is 1 to 4 / 3 of the thickness of the cushion body to which it is accommodated;

[0020] And / or, the height h2 and width W1 of the convex edge are equal.

[0021] A laser processing device according to a second aspect of the present invention includes a support and a galvanometer connecting plate, wherein a bionic gasket as described in any of the above claims is provided between the support and the galvanometer connecting plate.

[0022] The laser processing equipment according to embodiments of this utility model has at least the following beneficial effects: By introducing the aforementioned biomimetic gasket, vibrations generated during the operation of the laser processing equipment can be more effectively absorbed and buffered. This significantly improves the stability of the laser beam, thereby increasing processing accuracy and ensuring the stability and consistency of product quality. Furthermore, the biomimetic gasket can reduce stress concentration within the equipment, lowering the risk of material fatigue failure. Compared to ordinary rubber gaskets, the service life of the biomimetic gasket is significantly extended, thereby reducing the maintenance frequency and cost of the equipment and improving its overall reliability and durability.

[0031] Laser processing equipment often incorporates rubber pads or rings for vibration damping. However, with ordinary rubber pads, significant internal stress can develop after installation. This is because the rubber pad's shape changes under the weight of the equipment and external vibrations, while the inherent elasticity of the rubber material causes internal stress. This high stress accelerates the aging of the rubber pad, as it promotes the breakage and recombination of rubber molecular chains, reducing its elasticity and mechanical properties. Furthermore, under prolonged vibration and stress, the rubber pad is highly susceptible to fatigue failure, losing its vibration damping function and consequently affecting the normal operation and processing accuracy of the laser processing equipment.

[0032] Therefore, referring to Figure 1This invention proposes a biomimetic washer, comprising a first washer 100 and a second washer 200 stacked on top of each other. One of the first washer 100 and the second washer 200 has a recessed portion 110, and the other has an arched portion 210. For example, the first washer 100 is the upper washer, and its lower surface has a recessed portion 110, which can be hemispherical, conical, or other suitable geometric shapes. The second washer 200 is the lower washer, and its upper surface has an arched portion 210 that matches the recessed portion 110 of the first washer 100. The shape of the arched portion 210 corresponds to the recessed portion 110 to achieve a good fit.

[0033] In a specific embodiment, when the laser processing equipment vibrates, the weight of the equipment and the force generated by the vibration act on the bionic washer. At this time, the first pad 100 and the second pad 200 begin to bear pressure. Under pressure, the arched portion 210 undergoes downward elastic deformation, while the recessed portion 110 undergoes upward elastic deformation due to the compression of the arched portion 210. This deformation is not a simple material compression, but a change in the overall shape of the pad. For example, when the arched portion 210 is hemispherical, during the process of being stressed, the hemispherical arched portion 210 will gradually be flattened, and its shape will gradually change from hemispherical to flat; while the recessed portion 110 will gradually become flat from its original recessed state. Due to the special shape design of the recessed portion 110 and the arched portion 210, the stress will be evenly distributed in all parts of the pad during the deformation process. Compared with ordinary rubber pads, when ordinary rubber pads are stressed, the stress is mainly concentrated in the pressure area, which can easily lead to excessive local stress, accelerating material aging and fatigue failure. The biomimetic washer of this invention, through the cooperation of the recessed portion 110 and the arched portion 210, allows stress to be evenly distributed along the structure of the washer, avoiding the problem of stress concentration. When the vibration disappears or the pressure decreases, the first washer 100 and the second washer 200 rely on the elastic restoring force of their own materials; the arched portion 210 gradually returns to its original shape, and the recessed portion 110 correspondingly returns to its concave shape. This elastic deformation is reversible, and the washer can withstand multiple vibrations without easily being damaged.

[0034] It should be noted that ordinary rubber pads mainly rely on material compression for shock absorption when subjected to force. During long-term compression and recovery, the molecular chains of the material continuously break and recombine, leading to a decline in material performance. In contrast, the biomimetic washer of this invention uses the elastic deformation of the arched portion 210 and the recessed portion 110 to replace material compression, reducing stress concentration and fatigue damage within the material, thereby extending the service life of the washer.

[0035] In a specific embodiment, the location of maximum stress in a conventional washer shifts from the upper and lower edges of the central through hole to the center of the through hole, i.e., along the height direction, resulting in a 62.65% decrease in maximum stress. In contrast, the maximum stress on the upper and lower surfaces of the biomimetic washer proposed in this invention is reduced by 84.18% compared to a conventional washer, and the stress is distributed more evenly.

[0036] In Embodiment 1, the first pad 100 and the second pad 200 are connected at the center. The first pad 100 is made of a rubber material with a certain degree of elasticity and is molded to form a structure with a recessed portion 110. The shape of the recessed portion 110 can be hemispherical or other suitable shapes. The second pad 200 is also made of rubber material and has an arched portion 210, the shape of which matches the recessed portion 110 of the first pad 100. The first pad 100 and the second pad 200 are stacked one on top of the other, so that the center of the recessed portion 110 of the first pad 100 abuts against the center of the arched portion 210 of the second pad 200. At the abutment, an appropriate amount of glue or other adhesive can be applied to make the two tightly bonded, forming an integrated structure. The fabricated bionic gasket is installed in the corresponding position of the laser processing equipment, such as between the equipment base and the ground or between components inside the equipment that require vibration damping. When the equipment is running, the vibration generated is transmitted to the washer through the equipment. The first washer body 100 and the second washer body 200, through the cooperation of the recessed part 110 and the arched part 210, evenly disperse and absorb the vibration energy, thereby playing a good role in shock absorption.

[0037] In Embodiment 2, the first pad 100 and the second pad 200 are integrated in the middle. Specifically, two-color injection molding or other one-piece molding processes are used to simultaneously manufacture the first pad 100 and the second pad 200. During the manufacturing process, one color of rubber material is first injected to form the portion of the first pad 100 with the recessed portion 110. Then, another color of rubber material is injected to form an arched portion 210 at the position of the recessed portion 110 of the first pad 100, making the middle portion of the recessed portion 110 and the middle portion of the arched portion 210 integrally set. The one-piece molded bionic washer is installed on a laser processing equipment. When the equipment is running, the vibration generated is transmitted to the washer through the equipment. The first pad 100 and the second pad 200 of the washer, through the interaction of the recessed portion 110 and the arched portion 210, evenly disperse and absorb the vibration energy, thereby achieving a good shock absorption effect.

[0038] In Embodiment 3, the first pad 100 and the second pad 200 have an edge-abutting structure. Specifically, the first pad 100 has a recessed portion 110, and the second pad 200 has an arched portion 210. The shape and size of the recessed portion 110 and the arched portion 210 are designed according to actual needs to ensure that they can fit together. The first pad 100 and the second pad 200 are stacked one on top of the other, so that the edge of the recessed portion 110 of the first pad 100 abuts against the edge of the arched portion 210 of the second pad 200. Mechanical fixing, such as using bolts or screws, can be used at the abutment point to secure them together, or adhesive bonding can be used to ensure a tight bond. The assembled bionic washer is installed on a laser processing device to achieve a shock absorption function.

[0039] In embodiment four, the first pad 100 and the second pad 200 are integrally formed at their edges. Specifically, the first pad 100 and the second pad 200 are integrally molded using a special mold design and injection molding process. During the molding process, the edges of the recessed portion 110 of the first pad 100 and the edges of the arched portion 210 of the second pad 200 are integrally formed, creating a single biomimetic washer. The integrally molded biomimetic washer is then mounted on a laser processing device to perform its shock-absorbing function.

[0040] By configuring a first gasket 100 and a second gasket 200, one including a recessed portion 110 and the other including an arched portion 210, the middle portions of the recessed portion 110 and the middle portions of the arched portion 210 abut or are integrally formed, or the edges of the recessed portion 110 and the edges of the arched portion 210 abut or are integrally formed. This structure allows for a more uniform distribution of stress when the gasket is under pressure, avoiding the problem of stress concentration inside ordinary rubber gaskets, thereby reducing the stress level inside the gasket and extending its service life. Due to the reduction in internal stress, the elastic properties of the gasket are better maintained, enabling it to more effectively absorb and buffer vibrations generated by laser processing equipment, reducing the impact of vibrations on the equipment, and improving the precision and quality of laser processing. Furthermore, the integrally formed structure enhances the overall strength and stability of the gasket, making it less prone to deformation and damage during long-term use, ensuring the durability of the shock absorption effect.

[0041] Reference Figure 1In some embodiments, the first gasket 100 has a recess 110, and the second gasket 200 has an arched portion 210. These two portions are connected at the middle by an integrated design to form a single structure. Furthermore, the middle portions of the recess 110 and the arched portion 210 are not only integrated but also continuous, meaning they are continuous from the inside out. Simultaneously, the inner edges of the recess 110 and the arched portion 210 are also connected by an integrated design to form a complete washer structure. This integrated design significantly enhances the structural stability and durability of the washer, reduces relative movement and wear between components, thereby improving the overall service life and reliability of the washer. At the same time, the continuous and integrated design further enhances the strength and stability of the washer while reducing material usage, making the washer lighter and with better performance. In addition, this design also helps improve the shock absorption performance of the washer, enabling it to better adapt to different working environments and conditions.

[0042] Reference Figure 1 Preferably, the radial connection length L3 between the recessed portion 110 and the arched portion 210 is designed to be 1 / 4 to 1 / 3 of the bending arc length L2 of the arched portion 210. This proportional relationship ensures the rationality and stability of the connection, being neither too long nor too short, and effectively balancing the strength and flexibility of the washer. This balance allows the washer to more effectively distribute stress under load, avoiding excessive local wear. Simultaneously, it also helps improve the washer's shock absorption performance and adaptability, enabling it to better adapt to different working environments and conditions.

[0043] Preferably, the radial connection length L3 of the recessed portion 110 and the arched portion 210 is precisely set to 1 / 4 of the bending arc length L2 of the arched portion 210, which ensures that the gasket can maintain the best mechanical properties when under stress, maximizes the uniformity of stress distribution of the gasket, further extends its service life, and also makes the manufacturing and installation of the gasket more convenient and reduces production costs.

[0044] Preferably, the bending arc length L1 of the recessed portion 110 is less than or equal to the bending arc length L2 of the arched portion 210, ensuring that the recessed portion 110 and the arched portion 210 can deform in a coordinated manner when subjected to force, avoiding excessive stress on a certain part, thereby improving the durability of the gasket, and also helping to improve the shock absorption performance and adaptability of the gasket.

[0045] Preferably, the bending arc length L1 of the recess 110 is set to be 0.9 to 1 times the bending arc length L2 of the arch 210. This near 1:1 ratio ensures that the recess 110 and the arch 210 remain synchronized during deformation, further optimizing stress distribution, improving the service life and reliability of the gasket, and also making the manufacturing and installation of the gasket more convenient and reducing production costs.

[0046] Reference Figure 1 In a specific embodiment, one of the first pad 100 and the second pad 200 has an outwardly protruding edge 300. The inner side of the outwardly protruding edge 300 is used to accommodate the other pad, making the gasket more stable during installation and use, less likely to fall off or shift, significantly enhancing the stability and reliability of the gasket, and preventing the gasket from falling off or shifting during use.

[0047] Furthermore, the height h2 of the convex edge 300 is designed to be 1 to 4 / 3 times the thickness of the gasket it accommodates. Simultaneously, the height h2 and width W1 of the convex edge 300 are equal to ensure the overall stability and aesthetics of the gasket.

[0048] This invention also proposes a laser processing device using the aforementioned bionic washer, comprising a support and a galvanometer connecting plate, wherein the aforementioned bionic washer is disposed between the support and the galvanometer connecting plate. Specifically, in processing steps such as marking, tab welding, and shell welding, the precision laser processing station is highly susceptible to vibration. To reduce the impact of vibration on laser processing, the aforementioned bionic washer is used between the support and the galvanometer connecting plate. This reduces the impact of vibration and lowers the internal stress of the washer after installation, thereby increasing its service life.

[0049] By introducing the aforementioned biomimetic washers, vibrations generated during laser processing equipment operation can be more effectively absorbed and buffered. This significantly improves the stability of the laser beam, thereby enhancing processing accuracy and ensuring the stability and consistency of product quality. Furthermore, the biomimetic washers reduce internal stress concentration, lowering the risk of material fatigue failure. Compared to ordinary rubber pads, the biomimetic washers have a significantly longer service life, reducing maintenance frequency and costs, and improving the overall reliability and durability of the equipment.

[0050] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
