Abstract
Description
Technical Field
[0001] The invention belongs to the field of precision component transportation, and more specifically, relates to a transportation vibration reduction tooling and a use method thereof. Background Art
[0002] As a key equipment for manufacturing chips and producing large-scale integrated circuits, the packaging and transportation process of the lithography machine requires extremely high professionalism and precision. In particular, the lithography machine contains precision components such as optical components. If you do not pay attention to shock protection during transportation, it will cause damage to the optical components. The existing packaging and transportation methods are as follows: 1. Shockproof: Air cushions are added throughout the transportation of the lithography machine to prevent internal damage due to vibration. 2. Fixation: During transportation, the lithography machine is fixed to the vehicle with ropes, steel wire ropes, steel plates and other materials to avoid damage caused by collisions or bumps during driving. However, the air cushions added during transportation are only roughly isolated, and the level and effect of vibration isolation cannot be determined. Fixing with ropes can only avoid shaking, but cannot eliminate vibration.
[0003] Corresponding improvements have also been made to address the above problems, such as the Chinese patent application number CN201810592352.9, published on November 2, 2018. The patent discloses a storage box for storing and transporting micro-precision parts, including a box body, a punching plate and a shock-absorbing seat. The inner wall of the box body is provided with a plurality of slides perpendicular to the bottom surface of the box body, and the lowest and highest points of the slides are respectively located on the same horizontal plane. The buffer plate is slidably connected to the slides through the sliders provided on its edge. The shortcomings of this patent are: the structure is complex and the vibration reduction effect is not obvious when encountering impact force.
[0004] Another example is Chinese patent application number CN201210041165.4, published on September 11, 2013. The patent discloses a transport cart for carrying high-precision workpieces, including: a base; casters, mounted at the bottom of the base; fixed support feet, mounted on the base, including a locking mechanism for recording the height of the support feet; a lifting and locking mechanism, mounted on the top of the base; a pallet, connected and arranged above the lifting and locking mechanism, which adjusts the height of the pallet; an airbag support, fixedly connected to the side of the pallet; an air-floating support, fixedly connected to the transported workpiece; and a clamping tool, arranged on the base, so that the side of the pallet fits the side of the installation surface of the transported workpiece; a vertically mounted airbag is provided on the airbag support, which is installed on the side of the transported workpiece, one end of which is fixed on the airbag support, and the other end is equipped with a roller mechanism; an air-floating block is provided on the air-floating support. The disadvantage of this patent is that although it can realize the rapid loading and unloading of precision parts and accurately place them in the designated installation position, the structure is too complicated and the cost is high. Summary of the invention
[0005] 1. Problems to be solved In view of the problem that the existing precision parts have poor vibration reduction and complex structure during transportation, the present invention provides a transportation vibration reduction tool and a method for using the same. The present invention adjusts the impact force received by the second bottom plate through multiple layers of means, so that when the first bottom plate encounters an impact force, the impact force reaching the second bottom plate is negligible, which greatly improves the vibration reduction effect of the second bottom plate, so that the precision optical components placed on the second bottom plate during transportation can be protected from damage during transportation, thereby ensuring the quality of the precision optical components.
[0006] 2. Technical solution To solve the above problems, the present invention adopts the following technical solutions.
[0007] A transport vibration reduction tooling includes a first bottom plate, a second bottom plate and a connecting piece, a support column is arranged between the first bottom plate and the connecting piece, and the first bottom plate supports the second bottom plate and the connecting piece through the support column; a buffer column is arranged between the second bottom plate and the connecting piece, and the arrangement of the buffer column makes the second bottom plate hang above the first bottom plate, and an elastic member is arranged on the buffer column, and the elastic member is determined as follows: Determine a first preset value of the elastic member, simulate the transport vibration reduction tooling, obtain a vibration reduction result, and adjust the first preset value of the elastic member based on the vibration reduction result so that the vibration reduction result of the transport vibration reduction tooling meets the target requirement; the first preset value of the elastic member includes the stiffness of the elastic member and / or the setting position on the buffer column.
[0008] By adopting the above technical solution, the second bottom plate is firstly suspended above the first bottom plate, so that the second bottom plate itself has a certain degree of freedom to respond to external vibrations. When the first bottom plate is subjected to external impact force, the second bottom plate can generate displacement or shaking to a certain extent to absorb and disperse part of the vibration energy, thereby achieving a vibration reduction effect; Secondly, the setting of the connecting member lengthens the overall force transmission route. When the first bottom plate is subjected to external impact force, the force will first be transmitted to the connecting member through the support column, then transmitted to the buffer column through the connecting member, and finally reaches the second bottom plate, so that the second bottom plate does not directly bear the impact force of the first bottom plate, reducing the transmission efficiency of vibration, and then greatly reducing the impact force on the second bottom plate, achieving a vibration reduction effect; Finally, by arranging an elastic member on the buffer column, when the first bottom plate is subjected to external impact force, the energy generated by the impact or vibration is absorbed and dispersed by the elastic member, thereby reducing the impact force transmitted to the second bottom plate; and because the elastic member has a certain deformation ability, it can isolate the vibration transmission between the first bottom plate and the second bottom plate to a certain extent, thereby further reducing the vibration influence on the second bottom plate and achieving a vibration reduction effect; and the setting of the elastic member is also verified and determined through simulation calculations, avoiding the problem of unsatisfactory vibration reduction effect caused by blindly setting the elastic member, and further ensuring the stability and effect of the entire vibration reduction process.
[0009] The impact force received by the second bottom plate is adjusted through multi-layer means, so that when the first bottom plate encounters an impact force, the impact force reaching the second bottom plate is negligible, which greatly improves the vibration reduction effect of the second bottom plate, so that the precision optical components placed on the second bottom plate during transportation can not be damaged during transportation, thereby ensuring the quality of the precision optical components; and the whole tooling structure is simple, the number of components used is small, and the space is reasonably used, so that the volume of the whole tooling can be small, and the production cost is greatly reduced.
[0010] Furthermore, adjusting the preset value of the elastic member specifically includes: replacing the elastic member with a different stiffness, and / or replacing the elastic member with a different setting position on the buffer column along the length direction of the buffer column.
[0011] By adopting the above technical solution, there are two means of adjusting the preset value: directly replacing elastic parts with different stiffness, which is convenient to operate and efficient; directly replacing different setting positions of elastic parts on the buffer column. This method does not need to introduce multiple elastic parts, will not cause waste of resources, and saves costs.
[0012] Furthermore, the method further includes determining the stiffness of the transport vibration reduction tooling, which is determined in the following manner: obtaining second preset values of the support column and the buffer column, simulating the transport vibration reduction tooling, obtaining stiffness test results, and adjusting the second preset value of the support column based on the stiffness test results, so that the stiffness of the transport vibration reduction tooling meets the preset requirements; the second preset values of the support column and the buffer column are the stiffness of the support column and the buffer column respectively; When the second preset value of the support column satisfies the stiffness of the transport vibration reduction tooling and meets the preset requirements, the transport vibration reduction tooling is simulated to obtain the vibration reduction result, and the first preset value of the elastic member and the second preset value of the buffer column are adjusted based on the vibration reduction result so that the vibration reduction result of the transport vibration reduction tooling meets the target requirements; Determine the final first preset value of the elastic member and the final second preset values of the support column and the buffer column.
[0013] By adopting the above technical solution, when the entire transport vibration reduction tooling meets the vibration reduction requirements, in order to avoid the phenomenon that the support column and the buffer column have good vibration reduction performance but insufficient rigidity, and cannot provide rigid support for the entire transport vibration reduction tooling, resulting in insufficient strength and poor stability of the entire transport vibration reduction tooling, a rigidity test is performed on the transport vibration reduction tooling to ensure that it meets the vibration reduction performance while ensuring good strength and stability, and meet the safety requirements; And the stiffness of the support column is adjusted to meet the stiffness requirement. Since the support column plays a supporting role between the first bottom plate, the second bottom plate and the connecting member, and its stiffness as a supporting core component directly affects the stability of the overall structure, adjusting the stiffness of the support column can achieve the purpose of quickly adjusting the overall stiffness, and the adjustment effect is intuitive and good; After determining that the transport vibration reduction fixture meets the stiffness requirements, the transport vibration reduction fixture is tested for vibration reduction again. This is because when the transport vibration reduction fixture as a whole meets the stiffness requirements, the stiffness of the support column is changed, which will indirectly cause the vibration reduction effect of the entire transport vibration reduction fixture to change. The buffer column and the elastic part directly affect the vibration reduction effect of the overall structure. Therefore, the preset values of these two components are adjusted to achieve the overall vibration reduction effect. Finally, the transport vibration reduction fixture meets both the strength requirements and the vibration reduction requirements, has a good vibration reduction effect and has high stability.
[0014] Furthermore, the connecting member is a support frame arranged above the second bottom plate, and the support frame is provided with an insertion channel for placing items on the second bottom plate.
[0015] By adopting the above technical solution, a support frame is used as a connecting member, which has a simple structure and will not interfere with the first base plate and the second base plate, making it easy to assemble; at the same time, the setting of the insertion channel makes it easy to place optical components and other precision components that need to be transported on the second base plate.
[0016] Furthermore, the length and width of the support frame are the same as the length and width of the first base plate, and the support columns are arranged at the four corners of the first base plate; the length of the second base plate is smaller than the length of the first base plate, the width of the second base plate is smaller than the width of the first base plate, and the buffer columns are arranged at the midpoints of the four sides of the second base plate.
[0017] By adopting the above technical solution, the setting here sets the size of the support frame to be consistent with the size of the first base plate, so that the entire transport vibration reduction tooling occupies a smaller overall area and is easy to fix and transport; the size of the second base plate is designed to be smaller than that of the first base plate, so that the second base plate will not easily interfere with and collide with the outside world, and at the same time, it can be easier to achieve the degree of freedom required by the second base plate, thereby more effectively absorbing and dispersing vibration energy, thereby improving the vibration reduction effect.
[0018] Furthermore, the four corners of the second bottom plate are bent downward toward the second bottom plate to form an "L" shape, so that the second bottom plate is in a "cross" shape. By adopting the above technical solution, the cross-shaped design ensures that the second base plate will not interfere with the corner of the first base plate when being installed, further ensuring the convenience of installation and improving installation efficiency; at the same time, the L-shaped design at the corner of the second base plate increases the stability of the structure, making it less prone to deformation or damage, thereby ensuring the safety and stability of items placed on the second base plate.
[0019] Furthermore, the elastic member is a rubber block, and the rubber block is arranged along the length direction of the buffer column; and also includes a mounting groove opened on the buffer column along the length direction of the buffer column, and the rubber block is placed in the mounting groove.
[0020] By adopting the above technical scheme, a rubber block is used as an elastic member. The rubber block has high elasticity, can withstand repeated compression and stretching, absorbs vibration energy well and has low cost. At the same time, the rubber block is installed on the buffer column by opening an installation groove. The structure is stable, which makes it difficult for the rubber block to shake, thereby ensuring a good vibration reduction effect.
[0021] Furthermore, an elastic part is also provided on the surface of the second bottom plate, and the stiffness of the elastic part provided on the surface of the second bottom plate is smaller than the stiffness of the elastic part provided on the buffer column, and the deformation capacity of the elastic part provided on the surface of the second bottom plate is smaller than the deformation capacity of the elastic part provided on the buffer column.
[0022] By adopting the above technical solution, elastic parts are also provided on the surface of the second bottom plate to further consolidate the vibration reduction effect of the second bottom plate; and the parameters of the elastic parts on the surface of the second bottom plate are designed differently from the parameters of the elastic parts on the buffer column, so that vibration reduction with different effects is carried out according to different stress conditions, thereby avoiding waste of resources and increasing costs.
[0023] Furthermore, the elastic member on the second bottom plate covers the surface of the second bottom plate, and the elastic member on the buffer column is arranged at the middle and upper part of the buffer column, so as to further enhance the vibration reduction effect.
[0024] A method for using a transport vibration reduction tooling comprises the following steps: S1: Assembling the transport vibration reduction tooling as described in any of the above items; S2: Place the optical precision components to be transported on the second base plate, and then fix the first base plate on the transport vehicle to complete the transportation.
[0025] By adopting the above technical solution, the method of using the transport vibration reduction tooling is simple to operate and does not require complicated and tedious steps. In addition, by fixing the first base plate on the transport vehicle, when the first base plate is subjected to external impact or collision, the force transmitted to the optical components on the second base plate will be greatly reduced, thereby achieving the vibration reduction effect and ensuring that the optical precision components are not damaged. BRIEF DESCRIPTION OF THE DRAWINGS
[0026] Figure 1 It is a structural schematic diagram of the present invention; In the figure: 1, first bottom plate; 2, second bottom plate; 3, connecting member; 4, elastic member. DETAILED DESCRIPTION
[0027] The present invention is further described below in conjunction with specific embodiments and drawings.
[0028] like Figure 1 As shown, a transport vibration reduction tooling comprises a first bottom plate 1, a second bottom plate 2 and a connecting member 3, a support column is arranged between the first bottom plate 1 and the connecting member 3, and the first bottom plate 1 supports the second bottom plate 2 and the connecting member 3 through the support column; a buffer column is arranged between the second bottom plate 2 and the connecting member 3, and the arrangement of the buffer column makes the second bottom plate 2 hang above the first bottom plate 1, and an elastic member 4 is arranged on the buffer column, and the elastic member 4 is determined as follows: Determine the first preset value of the elastic member 4, simulate the transport vibration reduction tooling, obtain the vibration reduction result, adjust the first preset value of the elastic member 4 based on the vibration reduction result so that the vibration reduction result of the transport vibration reduction tooling meets the target requirements; the first preset value of the elastic member includes the stiffness of the elastic member 4 and / or the setting position on the buffer column. Specifically, simulating the transport vibration reduction tooling here means to establish a simulation model with the transport vibration reduction tooling as a model, and then use the impact vibration received during transportation as a disturbance force input into the simulation model for simulation calculation to obtain the vibration reduction result. It is explained here that: since the impact vibration received during transportation is an uncertain factor, it is greatly affected by road conditions and other environmental factors, and on-site detection of impact vibration will also waste a lot of manpower, material and financial resources; therefore, in order to improve the accuracy and convenience of the simulation results, the national military standard is selected as the impact vibration as input, and the vibration reduction result actually achieved by the simulation tooling is simulated, which theoretically verifies the vibration isolation performance of the tooling and quantitatively ensures the safety of precision components such as optical components during transportation; at the same time, the simulation calculation can use the existing simulation calculation, which will not be described in detail in this application.
[0029] In this embodiment, the first bottom plate 1 is used to contact with an external transport vehicle or external transport component to complete the fixation of the entire transport vibration reduction tooling; the second bottom plate 2 is used to place optical components or other precision components; so that when the entire optical component or other precision component is transported, the transportation can be completed by fixing the first bottom plate 1. The overall structure is simple, and the entire transport vibration reduction tooling frame is basically hollow, with few components and low cost; at the same time, the vibration reduction process of the transport vibration reduction tooling is as follows: First, the second bottom plate 2 is suspended above the first bottom plate 1, so that the second bottom plate 2 has a certain degree of freedom to respond to external vibrations. When the first bottom plate 1 is subjected to external impact force, the second bottom plate 2 can generate displacement or shaking to a certain extent to absorb and disperse part of the vibration energy, thereby achieving a vibration reduction effect; Secondly, the setting of the connecting member 3 extends the overall force transmission route. When the first bottom plate 1 is subjected to external impact force, the force will first be transmitted to the connecting member 3 through the support column, and then transmitted to the buffer column through the connecting member 3, and finally reach the second bottom plate 2, so that the second bottom plate 2 does not directly bear the impact force of the first bottom plate 1, reducing the transmission efficiency of vibration, and then greatly reducing the impact force on the second bottom plate 2, achieving a vibration reduction effect; Finally, by arranging an elastic member 4 on the buffer column, when the first bottom plate 1 is subjected to external impact force, the energy generated by the impact or vibration is absorbed and dispersed by the elastic member 4, thereby reducing the impact force transmitted to the second bottom plate 2; and because the elastic member 4 has a certain deformation ability, it can isolate the vibration transmission between the first bottom plate 1 and the second bottom plate 2 to a certain extent, thereby further reducing the vibration influence on the second bottom plate 2 and achieving a vibration reduction effect; and the setting of the elastic member 4 is also verified and determined through simulation calculations, because different elastic members 4 have different stiffnesses, which means that their deformation abilities are different, and the corresponding costs will also be different. The setting of the elastic member 4 is determined through simulation calculations, which can ensure a good vibration reduction effect while avoiding waste of costs.
[0030] Therefore, the transport vibration reduction tooling in the present application adjusts the impact force exerted on the second base plate 2 through multi-layer means, so that when the first base plate 1 encounters an impact force, the impact force reaching the second base plate 2 is negligible, thereby greatly improving the vibration reduction effect of the second base plate 2, so that the precision optical components placed on the second base plate 2 during transportation will not be damaged during transportation, thereby ensuring the quality of the precision optical components; and the entire tooling structure is simple, with few components used and reasonable use of space, so that the volume of the entire tooling can be small, while greatly reducing the production cost.
[0031] In a specific embodiment, adjusting the preset value of the elastic member 4 specifically includes: replacing the elastic member 4 with a different stiffness, and / or replacing the elastic member 4 at a different setting position on the buffer column along the length direction of the buffer column.
[0032] After continuous simulation calculations, the stiffness range of the elastic member 4 meets 800-1200N / mm, which can ensure a better vibration reduction effect; or the elastic member 4 is set at the upper position of the buffer column, which can ensure a better vibration reduction effect. Directly replacing the elastic member 4 is simple, fast and efficient; replacing the setting position of the elastic member 4 on the buffer column does not require the use of multiple elastic members 4, which will not cause waste of resources and reduce costs. Both methods take into account efficiency and cost and are highly flexible.
[0033] In a specific embodiment, the method further includes determining the stiffness of the transport vibration reduction tooling, which is determined in the following manner: obtaining second preset values of the support column and the buffer column, simulating the transport vibration reduction tooling, obtaining stiffness test results, and adjusting the second preset value of the support column based on the stiffness test results so that the stiffness of the transport vibration reduction tooling meets the preset requirements; the second preset values of the support column and the buffer column are the stiffness of the support column and the buffer column respectively; When the second preset value of the support column satisfies the stiffness of the transport vibration reduction tooling and meets the preset requirements, the transport vibration reduction tooling is simulated to obtain the vibration reduction result, and the first preset value of the elastic member 4 and the second preset value of the buffer column are adjusted based on the vibration reduction result so that the vibration reduction result of the transport vibration reduction tooling meets the target requirements; The final first preset value of the elastic member 4 and the final second preset values of the support column and the buffer column are determined.
[0034] Specifically, it should be noted in this embodiment that when the entire transport vibration reduction tooling meets the vibration reduction requirements, the second base plate 2 and the first base plate 1 are essentially a flexible connection. Although the flexible connection helps to reduce vibration, it will also reduce the overall rigidity of the structure, which will lead to poor stability of the entire transport vibration reduction tooling. Therefore: When the entire transport vibration reduction tooling meets the vibration reduction requirements, in order to avoid the problem that the support column and the buffer column have good vibration reduction performance but insufficient rigidity, and cannot provide rigid support for the entire transport vibration reduction tooling, resulting in insufficient strength and poor stability of the entire transport vibration reduction tooling, a stiffness test is performed on the transport vibration reduction tooling. The stiffness test is the same as the determination method of the previous elastic member 4, that is, a simulation model is established with the transport vibration reduction tooling, and then impact vibration is input to obtain the stiffness result; so that it can meet the vibration reduction performance while ensuring good strength and stability, and meet the safety requirements; And the stiffness of the support column is adjusted to meet the stiffness requirement, because the support column plays a supporting role between the first bottom plate 1, the second bottom plate 2 and the connecting member 3, and its stiffness as a supporting core component directly affects the stability of the overall structure, so adjusting the stiffness of the support column can achieve the purpose of quickly adjusting the overall stiffness, and the adjustment effect is intuitive and good; After determining that the transport vibration damping fixture meets the stiffness requirements, the transport vibration damping fixture is tested for vibration damping again. This is because when the transport vibration damping fixture as a whole meets the stiffness requirements, the stiffness of the support column is changed, which will indirectly cause the vibration damping effect of the entire transport vibration damping fixture to change. The buffer column and the elastic member 4 directly affect the vibration damping effect of the overall structure. Therefore, the preset values of these two components are adjusted to achieve the overall vibration damping effect. Finally, the transport vibration damping fixture meets both the strength requirements and the vibration damping requirements, and has a good vibration damping effect while having high stability.
[0035] In a specific embodiment, the connecting member 3 is a support frame arranged above the second bottom plate 2 , and the support frame is provided with an insertion channel for placing items on the second bottom plate 2 .
[0036] Specifically, in this embodiment, the support frame is rectangular in shape and has a simple structure, which is convenient for setting and connecting the support columns and the buffer columns, and will not interfere with the first base plate 1 and the second base plate 2, so it is easy to assemble; at the same time, the setting of the insertion channel facilitates the regular placement of optical components and other precision components that need to be transported on the second base plate 2.
[0037] In a specific embodiment, the length and width of the support frame are the same as the length and width of the first base plate 1, and the support columns are arranged at the four corners of the first base plate 1; the length of the second base plate 2 is smaller than the length of the first base plate 1, the width of the second base plate 2 is smaller than the width of the first base plate 1, and the buffer columns are arranged at the midpoints of the four sides of the second base plate 2.
[0038] Specifically, in this embodiment, restrictions are imposed on the support frame, the first base plate 1 and the second base plate 2. The support frame, the first base plate 1 and the second base plate 2 are all rectangular in shape, and the size of the support frame is set to the same size as the first base plate 1, so that the entire transport vibration reduction tooling occupies a smaller overall area and is easy to fix and transport; the size of the second base plate 2 is smaller than that of the first base plate 1, so that the second base plate 2 will not be subjected to external impact force before the first base plate 1, and the risk of interference or collision between the second base plate 2 and other external components is reduced, which helps to maintain the stability and reliability of the second base plate 2; and makes the installation process of the second base plate 2 simpler, reducing conflicts and coordination problems with surrounding components; at the same time, it is easier to achieve the degree of freedom required by the second base plate 2, thereby more effectively absorbing and dispersing vibration energy, thereby improving the vibration reduction effect.
[0039] In a specific embodiment, the four corners of the second base plate 2 are bent downward toward the second base plate 2 to form an "L" shape. The L-shaped bend at the corner not only increases the stability of the structure, but also improves the load-bearing capacity of the second base plate 2, so that it can withstand greater weight and pressure without being easily damaged or deformed; the second base plate 2 is made into a "cross" shape. The "cross" structure enables the second base plate 2 to utilize space more flexibly while maintaining sufficient strength, which can effectively reduce unnecessary material waste and meet specific space requirements; and more importantly, the second base plate 2 will not interfere with the corners of the first base plate 1 during installation, further ensuring the convenience of installation and improving installation efficiency.
[0040] In a specific embodiment, the elastic member 4 is a rubber block, which is arranged along the length direction of the buffer column; and also includes a mounting groove opened on the buffer column along the length direction of the buffer column, in which the rubber block is placed.
[0041] The rubber block is selected as the elastic member 4 because it has high elasticity, can withstand repeated compression and stretching, absorbs vibration energy well and has low cost; at the same time, the rubber block is installed on the buffer column by being placed in the installation groove, and the size of the installation groove matches that of the rubber block, so that the rubber block is limited and the shaking of the rubber block is avoided, thereby ensuring a good vibration reduction effect.
[0042] In a specific embodiment, an elastic member 4 is also provided on the surface of the second bottom plate 2, and the stiffness of the elastic member 4 provided on the surface of the second bottom plate 2 is smaller than the stiffness of the elastic member 4 provided on the buffer column, and the deformation capacity of the elastic member 4 provided on the surface of the second bottom plate 2 is smaller than the deformation capacity of the elastic member 4 provided on the buffer column.
[0043] In this embodiment, considering that the second base plate 2 is in direct contact with the optical precision components, in order to avoid friction damage between the second base plate 2 and the optical precision components, an elastic member 4 is also provided on the surface of the second base plate 2, thereby reducing the contact friction between the optical precision components and the second base plate 2, and further ensuring the quality of the optical precision components; at the same time, considering that the elastic member 4 on the second base plate 2 and the elastic member 4 on the buffer column have different vibration reduction functions, the elastic member 4 on the buffer column needs to absorb more energy, because the force is transmitted to the buffer column and then to the second base plate 2, and the force on the second base plate 2 itself is very weak. Therefore, the elastic member 4 on the second base plate 2 does not need to require high-performance vibration reduction effect, so the parameters of the elastic member 4 on the surface of the second base plate 2 are designed differently from the parameters of the elastic member 4 on the buffer column, and vibration reduction with different effects is performed for different force conditions to avoid waste of resources and increase in costs.
[0044] In a specific embodiment, the elastic member 4 on the second bottom plate 2 covers the surface of the second bottom plate 2, and the elastic member 4 on the buffer column is arranged in the middle and upper part of the buffer column, so as to further enhance the vibration reduction effect.
[0045] A method for using a transport vibration reduction tooling comprises the following steps: S1: Assembling the transport vibration reduction tooling as described in any of the above items; S2: placing the optical components to be transported on the second base plate 2, and then fixing the first base plate 1 on the transport vehicle to complete the transportation.
[0046] The method of using the transport vibration reduction tooling in the present application is simple to operate, does not require complicated and tedious steps, and by fixing the first base plate 1 on the transport vehicle, when the first base plate 1 is subjected to external impact or collision, the force transmitted to the optical components on the second base plate 2 will be greatly reduced, thereby achieving the effect of vibration reduction, and then ensuring that optical and other precision components are not damaged.
[0047] The examples described in the present invention are merely descriptions of the preferred implementation modes of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made to the technical solutions of the present invention by engineers and technicians in this field should all fall within the protection scope of the present invention.
