Description

Technical Field

[0001] This invention relates to the field of optical coating technology, specifically an easily detachable coating fixture. Background Technology

[0002] Coating refers to the process of depositing one or more layers of metal or dielectric thin films on the surface of optical components. The purpose is to change the reflection and transmission characteristics of the material surface to achieve requirements such as reducing or increasing light reflection, beam splitting, color separation, filtering, and polarization. Commonly used coating methods include vacuum coating and chemical coating. According to the performance of the thin film, common film layers include: reflective films, beam splitting films, filter films, and protective films. According to the structure of the thin film, it can be divided into single-layer films, double-layer films, and multi-layer films.

[0003] However, the existing technology has the following shortcomings: the current coating fixtures are generally divided into two types, one is an integrated structure and the other is a modular structure. The integrated structure is all the same size, while the modular structure allows the fixture body to be replaced, but the installation and disassembly are more complicated, which will cause delays before and after use. Therefore, an easily disassembled coating fixture is needed to change the current situation. Summary of the Invention

[0004] Other features and advantages of the invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and other accompanying drawings.

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide an easily detachable coating fixture, which can be placed in a storage box. When in use, it is assembled with the combination fixture and the replaceable fixture table. The fixture style on the replaceable fixture table can be changed accordingly, achieving the effect of one combination fixture for multiple units. At the same time, changing the replaceable fixture table is also simple to operate. After pulling out its plug rod, the limit clamp installation slide groove can be exited, effectively solving the cumbersome process of installation and disassembly.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an easily detachable coating fixture, comprising a coating fixture with an external placement box, a combined fixture body inside the coating fixture, a replaceable fixture platform mounted on the combined fixture body, and a plurality of combined blocks inside the combined fixture body. A plurality of limiting clips are mounted on the combined blocks, and each of the limiting clips has a plug inserted into it. A block body is provided inside the combined blocks, with an inner fixing block fixed to its inner outer wall. A side groove is formed on one side of the block body, and a protrusion is mounted on the other side. A sliding groove is formed on the surface of the block body, and an insertion hole is formed on the surface of the sliding groove. The blocks are mainly assembled by insertion, forming a combined block. By adapting the insertion of the plugs and limiting clips, the base of the coating fixture is completed, facilitating the installation and placement of the replaceable fixture platform for the corresponding coating process.

[0007] A further improvement to the present invention is that the block is composed of at least four pieces forming the combined block, which are connected by an interlocking method. The protruding block is adapted to the side groove, the sliding slot is an interconnected double sliding track, the insertion hole is nested with the insertion rod, the limiting clamp engages with the sliding slot, and the replaceable fixture table engages between a plurality of the limiting clamps. The blocks are joined together by their own side grooves and protruding blocks, thereby combining at least four blocks together. Simultaneously, under the action of the inner fixing block, a concave, hollowed-out square groove is formed, facilitating the limiting installation of the replaceable fixture table.

[0008] A further improvement to the invention is that the limiting clamp is provided with a connector strip, the connector strip having a plurality of through cross holes, and a plurality of inclined support columns fixed to the upper surface of the connector strip. A clamping block is connected to the top of each support column, one surface of the clamping block having a mating groove, and the other surface of the clamping block having a mating block fixed thereon. Two sliding block inserts are provided on the connector strip, and through cross holes are also provided on the surface of the sliding block inserts. By inserting the insert rod, the connector strip can be fixed to the surface of the block, and the connection between the blocks can be made more secure.

[0009] In a further improvement to the present invention, the insert strip engages with the sliding groove on the block on the same side, and is aligned with the insert hole by the through cross hole. The insert rod passes through the through cross hole, and the top of the insert rod is nested in the insert hole. The clamping blocks are placed opposite each other, and the mating grooves on the clamping blocks are inserted into the opposite direction of the inserting blocks. The clamping blocks adopt a relative connection method, and are combined with the inserting blocks by the mating grooves on their surfaces under reverse mating to form a limiting clamp on the replaceable fixture table, thereby ensuring the stability and centering of the replaceable fixture table.

[0010] A further improvement to the present invention includes a platform body within the replaceable fixture stage. A fixture cover is fixed to the top of the platform body, and a recessed clamping groove is formed on the platform body. A square locking block is fixed to the bottom of the platform body. A cover shell is provided inside the fixture stage, and a torsion shaft is installed at two opposite corners of the cover shell. An anti-detachment movable pad is fixed on the torsion shaft. A placement groove is formed inside the cover shell, and anti-detachment pads are installed on the inner walls at two opposite corners of the cover shell. The anti-detachment movable pad is generally elliptical in shape, nested on the torsion shaft, and positioned between the cover and the cover. Rotation of the torsion shaft allows it to be moved into the cover, thus restricting the edges and corners of the coated product.

[0011] A further improvement to the present invention is that the anti-detachment movable pad is disposed below the anti-detachment pad, the cover shell is engaged with the platform body, the recessed groove engages with the limiting clip, the anti-detachment movable pad is disposed between the cover shells, and the square locking block is engaged within the combined block. The square locking block mainly serves to restrict the platform body to ensure accurate insertion, allowing the platform carrier to be positioned and supported above the inner fixed block with the assistance of the square locking block.

[0012] A further improvement to the present invention includes a box base inside the placement box, a locking device mounted on the surface of the box base, a cover plate positioned opposite the locking device, a seat body inside the box base, and a recessed storage groove on the surface of the seat body. One side of the recessed storage groove has a circular hole groove, and the other side has a strip groove. Pins are inserted into both the circular hole groove and the strip groove. The circular hole groove and the strip groove are used for installing the locking device or the cover plate, respectively. The pins are inserted to fix both the locking device and the cover plate to the circular hole groove or the strip groove, ensuring both fixation and quick disassembly.

[0013] A further improvement to the present invention includes a sleeve within the locking device. The sleeve has a plurality of insertion holes on its surface. A directional pressure lock is mounted on the sleeve. The sleeve is connected to the circular slot via a pin, which is adapted to fit the insertion holes. The cover plate is installed within the strip groove. The directional pressure lock primarily functions by twisting the sleeve, thereby compressing and changing its orientation to restrict the cover plate, thus completing the cover closure.

[0014] A further improvement to the present invention is that the cover plate is provided with a hinge socket, a plate body is mounted on the hinge socket, an auxiliary slot is formed on the surface of the plate body, and a rotating shaft passes through the connection between the hinge socket and the plate body. The plate body is mainly used to cover the coating fixture, thereby protecting it from impacts or dust accumulation during storage when it is not in use.

[0015] In a further improvement to the present invention, the hinged socket engages within the strip groove and is secured by a through pin; the auxiliary slot on the plate cooperates with the steering lock; and the combination clamp is specifically placed within the recessed storage groove. The recessed storage groove is concave in overall shape, primarily designed to accommodate the placement of the combination clamp, ensuring that the combination clamp will not shift or fall off after placement. Beneficial effects

[0016] Compared with the prior art, the present invention has the following beneficial effects;

[0017] 1. This invention enables rapid assembly of the combination clamp with a replaceable clamping table. During assembly, simply connect the blocks together, then insert the rod through the sliding slot of the limiting clamp to secure the replaceable clamping table. This achieves the effect of one combination clamp with multiple units. Replacing the replaceable clamping table is also simple; simply pull out the rod and exit the limiting clamp through the sliding slot. This effectively solves the cumbersome process of installation and disassembly.

[0018] 2. This invention places the coating fixture inside the housing. When the product is no longer in use, it can be covered by a cover plate, allowing the top of the sleeve to support the auxiliary slot on the adapter plate. Then, the sleeve is turned and locked to store the coating fixture in the recessed storage slot in the housing. This prevents dust or collisions from occurring during placement and provides corresponding protection for the coating fixture. Attached Figure Description
