Description

Technical Field

[0001] The utility model relates to the technical field of positioning mechanisms, in particular to an optical glass coating positioning mechanism. Background Technique

[0002] Optical glass coating is a process of depositing one or more layers of metal or dielectric films on the surface of optical glass. This process aims to change the reflection and transmission characteristics of the material surface to meet specific optical requirements. Optical coating technology is widely used in various optical devices to improve their performance and efficiency.

[0003] During the optical glass coating process, the role of the positioning mechanism is to ensure the stability of the optical glass during the coating process, prevent it from moving or rotating, and thus ensure the quality and uniformity of the coating.

[0004] An optical glass surface coating positioning mechanism with the publication number of CN220745726U in the prior art includes a bottom plate. Fixed columns are installed at the four corners of the top end of the bottom plate. A top plate is installed at the top end of the fixed columns. Installation mechanisms are arranged at the four corners of the bottom end of the top plate. A positioning groove is penetrated through the inside of the top plate. Guide structures are arranged on both sides of the top end of the bottom plate. A lifting mechanism is arranged at the middle position of the top end of the bottom plate.

[0005] The size of the positioning groove on the top plate of this positioning mechanism is set, and it cannot position optical glass of different specifications. The overall versatility is poor, and it cannot simultaneously position and coat optical glass of different specifications. When coating a small number of optical glass of different specifications, batch operation is still required, which is rather troublesome. At the same time, after the optical glass is placed on the placement plate, the positioning operation is carried out. Since the top of the placement plate is flat and lacks corresponding limiting and positioning structures, etc., when placing the optical glass, the placement requirements for workers are relatively high. Once there is a mistake, it is easy to cause the optical glass to be crushed by the placement plate and the top plate. Therefore, improvements are proposed. Content of the Utility Model

[0006] The utility model is proposed to solve the disadvantages existing in the prior art, and provides an optical glass coating positioning mechanism.

[0007] To achieve the above purpose, the utility model adopts the following technical scheme: An optical glass coating positioning mechanism includes a placement plate. A plurality of fixed V-shaped clamping blocks are fixedly installed on the top of the placement plate. Matching movable V-shaped clamping blocks are arranged at the clamping ends of the plurality of fixed V-shaped clamping blocks. One ends of the plurality of movable V-shaped clamping blocks are fixedly connected with sliding rods. The outer surfaces of the plurality of sliding rods are hermetically and slidably sleeved with sliding sleeves, and the sliding sleeves are fixedly communicated with the placement plate.

[0008] One side of the outer surface of the placement plate is provided with a handwheel. One end of the handwheel is fixedly connected with a rotating shaft, and the rotating shaft penetrates through the placement plate. A plurality of mutual movement components are installed on the outer surface of the rotating shaft;

[0009] The movable ends of the plurality of mutual movement components are all installed with adjusting components, and the movable ends of the plurality of adjusting components are all fixedly installed with adjusting blocks;

[0010] The tops of the plurality of adjusting blocks are all fixedly connected with long plates, and the long plates are fixedly connected with the adjacent sliding rods.

[0011] Furthermore, the plurality of mutual movement components all include a bidirectional screw rod, and the bidirectional screw rod is fixedly sleeved on the outer surface of the rotating shaft. Two sliding seats are symmetrically threadedly sleeved on the outer surface of the bidirectional screw rod, and the two sliding seats can be synchronously driven to approach each other.

[0012] Furthermore, the plurality of adjusting components all include mounting seats, and the mounting seats are fixedly connected with the adjacent sliding seats. One side of the outer surface of the mounting seat is provided with a knob. One side of the outer surface of the knob is fixedly connected with a unidirectional screw rod, and the unidirectional screw rod penetrates through the mounting seat and is rotatably connected therewith. A slider is threadedly sleeved on the outer surface of the unidirectional screw rod, and the slider is fixedly connected with the adjacent adjusting block. The setting of the knob is beneficial to driving the unidirectional screw rod to rotate.

[0013] Furthermore, two guide rods are fixedly connected to the inner walls on both sides of the mounting seat, and the guide rods penetrate through the slider and are slidably connected therewith. The guide rods have a guiding effect on the slider and can ensure the stability of the slider movement.

[0014] Furthermore, the adjacent two adjusting blocks are arranged in a staggered manner to prevent the adjusting blocks from affecting the mutual approach of the adjacent two sliders.

[0015] Furthermore, anti-slip rubber pads are installed at the clamping ends of the fixed V-shaped clamping block and the movable V-shaped clamping block. The setting of the anti-slip rubber pads can prevent the V-shaped clamping block from making hard contact with the optical glass.

[0016] Furthermore, two bearing seats are symmetrically rotatably sleeved on the outer surface of the rotating shaft, and the bearing seats are fixedly connected with the placement plate. The bearing seats have a supporting effect on the rotating shaft and are beneficial to the installation of the rotating shaft.

[0017] The beneficial effects of the present utility model:

[0018] When the utility model is in use, for a kind of optical glass coating positioning mechanism, through the set fixed V-shaped clamp block, movable V-shaped clamp block, sliding rod, sliding sleeve, hand wheel, rotating shaft, mutual movement component, adjusting component, adjusting block and long plate, the whole can position and fix optical glasses of different specifications, improving the overall versatility. And when coating a small number of optical glasses of different specifications, it can also position optical glasses of different specifications at the same time, without the need for batch operation, increasing the overall practicality; at the same time, when placing, just place the optical glass between the fixed V-shaped clamp block and the movable V-shaped clamp block, reducing the placement difficulty.
