Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so as to enable those skilled in the art to more easily understand the advantages and features of the present invention, and thereby define the scope of the invention more clearly and clearly.
Referring to the drawings, a coating tool for a cylindrical optical element 6 comprises: frame 1, centre gripping subassembly, elastic block 3 and mounting 4. The clamping component is arranged on the outer frame 1 and is supported by the outer frame 1. For better support of the clamping assembly, a positioning cavity 11 is provided in the casing 1. The positioning cavity 11 is a large through hole, the clamping assembly is arranged in the positioning cavity 11 of the outer frame 1, and therefore two end faces of the clamping assembly cannot be shielded, two end faces of the optical element 6 cannot be shielded, and two end faces of the optical element 6 can be coated successively by one-time clamping.
The clamping assembly comprises a plurality of clamping blocks 2 arranged in rows, a plurality of clamping assemblies can be arranged on one outer frame 1, namely a plurality of rows of clamping blocks 2 can be arranged on one outer frame 1, and therefore the outer frame 1 can be used for clamping a plurality of optical elements 6, and efficiency is improved.
Two parallel side surfaces of the clamping blocks 2 are provided with clamping grooves 21, and the adjacent clamping blocks 2 clamp and fix the optical element 6 through the clamping grooves 21. The clamping grooves 21 on the clamping block 2 are one or more of V-shaped grooves, arc-shaped grooves or trapezoidal grooves, the cross-sectional shapes of the V-shaped grooves, the arc-shaped grooves and the trapezoidal grooves are respectively V-shaped, arc-shaped and trapezoidal, and the clamping grooves 21 in different shapes can be selected according to the end surface area of the optical element 6.
The number of the clamping grooves 21 on the same side surface of the clamping block 2 is two, and the two clamping grooves 21 arranged on one clamping block 2 can improve the efficiency and ensure the clamping firmness. More than two clamping grooves 21 are formed in one clamping block 2, so that the balance is poor in the clamping process, the clamping is easy to loose, and the falling phenomenon occurs. For each additional clamping block 2, two cylindrical optical elements 6 can be added, and so on, 2N cylindrical optical elements 6 can be fixed by N +1 clamping pieces.
In order to further effectively ensure that both end faces of the optical element 6 can be coated, the height of the holding block 2 may be set smaller than the height of the optical element 6 so that both end faces of the optical element 6 are exposed outside the holding block 2.
The side of the clamping block 2 contacting the outer frame 1 is provided with a fixing groove 22, and the clamping block 2 is connected with the outer frame 1 through the fixing groove 22. That is, the whole clamping block 2 is in an i shape, the clamping block 2 is clamped in the positioning cavity 11 of the outer frame 1 through the fixing groove 22, and the fixing groove 22 plays roles of sliding and limiting.
The elastic block 3 includes a support 31 and an elastic body 32, the support 31 is connected to the elastic body 32, and the elastic body 32 and the support 31 can be integrally formed. The support body 31 is provided with a support groove 311, and the shape of the support groove 311 is matched with the shape of the clamping groove 21 on the clamping block 2. The supporting body 31 is in contact with the optical element 6 through the supporting groove 311, that is, the supporting body 31 functions as one surface of the clamping block 2, and the supporting body 31 and the adjacent clamping block 2 cooperate to clamp and fix the optical element 6.
The elastic body 32 is mainly used for adapting to certain deformation, the elastic body 32 is arranged in a hollow structure, at least one of two parallel surfaces of the elastic body 32 and the supporting body 31 is provided with a gap, namely at least one of the two parallel surfaces of the elastic body 32 and the supporting body 31 is disconnected, namely the elastic body 32 forms two elastic supporting arms. Therefore, deformation of the buffering tool can be buffered when the external force impacts or high-temperature thermal expansion is carried out in the clamping process, so that the deformation is not influenced by the external force impacts or the high-temperature thermal expansion, and the optical element 6 is prevented from falling off.
In order to avoid the damage of the clamping block 2, the film coating tool further comprises a pressing block 5, wherein the pressing block 5 is arranged between the clamping block 2 and the fixing piece 4, and the pressing block 5 bears the pressure of the fixing piece 4. The hardness of the material of the pressing block 5 is greater than that of the material of the clamping block 2, and if the clamping block 2 is also made of a material with a greater hardness, the optical element 6 is easily damaged in the clamping process. The side of the pressing block 5 contacting with the outer frame 1 is provided with a fixing groove, the structure of the fixing groove is similar to that of the clamping block 2, and the pressing block 5 is connected with the outer frame 1 through the fixing groove.
