DETAILED DESCRIPTION OF THE EMBODIMENTS

[0032] The following further describes the present application in detail Figure 1-2 with reference to the accompanying drawings.

[0033] As Figure 1-2 , a lens automatic film - sticking and material - saving device includes a frame plate 1 in the shape of an alloy plate member. Four optical axis support pillars 35 are provided at the bottom of the frame plate 1 to be fixedly connected with the mounting plate 34 to support the frame plate 1. On both sides of the frame plate 1, two pairs of ear plate 31 assemblies are respectively fixedly connected. Each pair of ear plate 31 assemblies has two relatively arranged ear plates 31. Each ear plate 31 has a fixed bottom plate, a bending member, and a positioning rod. The fixed bottom plate is a metal sheet metal part and has a mounting groove 311 penetrating along its thickness direction at one end. A bending member is fixedly connected to the other end of the fixed bottom plate. One end of the bending member has a positioning rod, and the positioning rod is fixedly connected to the upper surface of the frame plate 1 for fixedly installing the ear plate 31;

[0034] On the installation grooves 311 of the two pairs of ear plates 31 components, there are provided synchronous belt driven wheels 32. Both ends of each synchronous belt driven wheel 32 are respectively inserted into the interior of the installation groove 311. A synchronous belt 33 is sleeved on the synchronous belt driven wheel 32, and the synchronous belt 33 can move in the same direction along the circumferential direction of the synchronous belt driven wheel 32. Between the synchronous belt 33 and the frame plate 1, there is provided a cavity plate 2. The cavity plate 2 is fixedly connected to the frame plate 1, and at its geometric center, there is a cavity recessed along its thickness direction for placing the lens to be film-coated. It should be noted that the distance between the synchronous belts 33 is greater than the diameter of the lens.

[0035] Below the mounting plate 34, there are provided two reinforcing plates 36 fixedly connected to the lower surface of the mounting plate 34 and arranged in parallel. Inside the space formed by the reinforcing plates 36 and the mounting plate 34, a driving device 37 is installed. The driving device 37 includes a motor 371. At one end of the motor 371, there is a driving gear 372. On one side of the driving gear 372, there is a driven gear 373 engaged with it. At the end of the driven gear 373 away from the driving gear 372, there is also provided a synchronous belt driving wheel 374. A synchronous belt 33 wound down from the synchronous belt driven wheel 32 is sleeved on the synchronous belt driving wheel 374. Among them, both the driving gear 372 and the driven gear 373 are bevel gears engaged with each other. By driving the driven gear 373 to drive the synchronous belt driving wheel 374 to rotate, under the action of the synchronous belt 33, the reciprocating movement of the synchronous belt 33 is realized.

[0036] It should be noted that on the mounting plate 34, there are also provided two through grooves 341 penetrating along its thickness direction for sleeving the synchronous belt 33 on the synchronous belt driven wheel 32 and the synchronous belt driving wheel 374.

[0037] The principle of the present utility model is as follows: First, the protective film is flatly adhered to the two synchronous belts 33. The output end of the motor 371 rotates to drive the driving gear 372 to work. The driving gear 372 drives the synchronous belt driving shaft to rotate, thereby driving the synchronous belt 33 to move forward, so that the protective film also moves accordingly. When the protective film completely covers the cavity plate 2, the film coating can be completed as needed.

[0038] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
