[0002] The coating process is widely used and is often used in metal processing, semiconductor industry, optoelectronic industry, etc. In recent years, due to the rapid development of semiconductor industry and optoelectronic industry, coating technology has made great progress. Optoelectronic industry coating refers to the process of coating a single layer or multiple layers of thin film on the surface of optical components by physical or chemical methods, and using the interference effect of incident, reflected and transmitted light on the thin film interface to achieve focusing, collimation, filtering, reflection and refraction effects.

[0003] When coating the lens, it is particularly important to fix the lens to be coated. If it cannot be fixed firmly, it will cause the material to scatter, which will not only cause cost loss, but also cause uneven coating of the lens, resulting in low production quality. The existing process of coating the lens usually places the lens on the coating jig first, then fixes the lens by gluing, and finally coats it, but this fixing method is cumbersome and unstable.

DETAILED DESCRIPTION

[0028] In order to make the purpose, features, and advantages of the present disclosure more obvious and easy to understand, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below in conjunction with the drawings in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0029] The embodiments of the present disclosure will be described in detail below with reference to the accompanying drawings.

[0030] Reference Figure 1As shown, a lens coating jig of an exemplary embodiment of the present disclosure includes a jig plate 1 and multiple sets of fixing components 2. The jig plate 1 is provided with multiple profiling holes 11 for accommodating lenses so that the lenses can be engaged in the profiling holes 11. Multiple sets of fixing components 2 are arranged on the jig plate 1, and multiple sets of fixing components 2 are correspondingly arranged beside each profiling hole 11. The fixing components 2 have a first position and a second position. When the fixing components 2 are in the first position, the fixing components 2 are separated from the lens; when the fixing components 2 are in the second position, the fixing components 2 are in contact with the lens to fix the lens.

[0031] In one embodiment, the fixture plate 1 includes a first surface and a second surface that are opposite to each other, the first surface is used for coating the lens, and the fixing component 2 is disposed on the second surface.

[0032] In this embodiment, the lens coating jig is suitable for the production process of eyeglass lenses. The profiling hole 11 on the jig plate 1 is profiling the lens to which it is adapted. In the actual production process, the design of the profiling hole 11 is not limited to a lens of a certain specific shape, and can be adaptively designed as needed. It can be understood that the shapes of the left and right lenses in a pair of glasses are symmetrical figures. Therefore, the profiling hole 11 on the same lens coating jig can be set in at least two shapes, and the two shapes correspond to the two symmetrical figures of the left and right lenses, respectively, and each two profiling holes 11 are set at a certain distance. The lens can be just snapped into the profiling hole 11, but it cannot be completely fixed. When it is subjected to external force, it will be displaced. Therefore, in the production process, coating the lens from the first side of the jig plate 1 will produce a force on the lens, which is easy to cause the lens to deviate. By setting a fixing component 2 on the second side of the jig plate 1, and manually adjusting the fixing component 2 to move from the first position to the second position and achieve fixation, the fixing component 2 extends into the profiling hole 11 and abuts against the lens, so that the lens coating will not deviate when subjected to external force, and can be firmly fixed.

[0033] Preferably, in one embodiment, two groups of fixing components 2 are arranged at the position of each contoured hole 11 .

[0034] In this embodiment, two groups of fixing components 2 are symmetrically arranged relative to the profiling hole 11, and can be arranged on the left and right sides of the profiling hole 11, or on the upper and lower sides of the profiling hole 11, so that the lens is evenly stressed and the two groups of fixing components 2 can fix the lens more firmly. It can be understood that only one group of fixing components 2 can be arranged at the position of each profiling hole 11, and the contact point between the fixing components 2 and the lens can be located at the center of the lens; or more than two groups of fixing components 2 can be arranged at the position of each profiling hole 11, which will not be described in detail here.

[0035] Reference Figure 2As shown, in one embodiment, the fixing assembly 2 includes a fastener 21 and a stopper 22, wherein the fastener 21 is disposed on the stopper 22 and is fastened to the fixture plate 1. The fastener 21 has a first state and a second state, wherein when the fastener 21 is in the first state, the stopper 22 is located at the first position; and when the fastener 21 is in the second state, the stopper 22 is located at the second position.

[0036] In this embodiment, the first position of the stopper 22 is any free position when the fastener 21 is in the first state, and the second position of the stopper 22 is the position where the stopper 22 is fixed against the lens when the fastener 21 is in the second state. The fastener 21 can be specifically a fastening screw, and a through hole is provided on the stopper 22. The fastener 21 passes through the through hole and is fastened to the fixture plate 1. Since the stopper 22 is sleeved on the fastener 21 and can move along the axial direction of the fastener 21, the distance between the stopper 22 and the fixture plate 1 can be adjusted by adjusting the locking depth of the fastening screw and the fixture plate 1. It can be understood that the thickness of the lens has various specifications, so the lens may protrude from the surface of the fixture plate 1. By adjusting the locking depth of the fastener 21 and the fixture plate 1, the farthest position of the stopper 22 relative to the fixture plate 1 in the axial direction of the fastener 21 is adjusted to adapt to the fixing of lenses of different thicknesses.

[0037] Further, refer to Figure 3 As shown, in one embodiment, the fixing assembly 2 further includes a first elastic member 23 , which is sleeved on the fastener 21 and abuts against the stopper 22 .

[0038] In this embodiment, the first elastic member 23 has a pressing function. By providing the first elastic member 23, the fixing assembly 2 can fix the lens more stably and firmly.

[0039] Reference Figure 4 As shown, in one embodiment, the fixing assembly 2 includes a knob structure 24, a second elastic member and a stopper 22, the second elastic member is located between the knob structure 24 and the fixture plate 1, and the stopper 22 is connected to the knob structure 24 and the second elastic member. The knob structure 24 can be rotated by an external force to compress or release the second elastic member, so as to drive the stopper 22 to be in the second position or the first position.

[0040] In this embodiment, the knob structure 24 includes a knob 241 and a connecting member 242 located in the middle of the knob 241, the connecting member 242 is fixedly connected to the knob 241 and is tightly connected to the fixture plate 1, the second elastic member is sleeved on the connecting member 242, and the two ends of the second elastic member are respectively in contact with the lower end of the knob 241 and the fixture plate 1, wherein the connecting member 242 can be specifically a screw, and the depth of the locking of the connecting member 242 and the fixture plate 1 can be changed by rotating the knob 241. One end of the stopper 22 is fixedly connected to a certain part of the second elastic member, thereby, when the operator controls the knob 241 to rotate, the depth of the connecting member 242 entering the fixture plate 1 changes, and the position of the knob 241 also changes. As the knob 241 compresses or releases the second elastic member, the position of the stopper 22 along the axis of the connecting member 242 changes, thereby achieving the fixing and release of the lens. Alternatively, one end of the stopper 22 is fixedly connected to the lower end of the knob 241, and the stopper 22 can rotate with the rotation of the knob 241. When the stopper 22 rotates to the second position, the other end of the stopper 22 can be fixedly abutted against the lens. The lens coating fixture in this embodiment has a simple structure, is easy to operate, is convenient for firmly fixing the lens, and has strong adaptability and can be used to fix lenses of different thicknesses.

[0041] Reference Figure 5 As shown, in one embodiment, the fixing assembly 2 includes a fixing member 25 and a sliding member 26 . The sliding member 26 is provided with a sliding groove 261 . The fixing member 25 is inserted into the sliding groove 261 and fixedly connected to the fixture plate 1 .

[0042] In this embodiment, the fixing member 25 can be a bolt, a screw or a rivet, etc. The fixing member 25 generally includes a column and a head. The diameter of the column of the fixing member 25 is adapted to the width of the slide groove 261, so that the sliding member 26 can move relative to the fixing member 25. The head of the fixing member 25 is pressed on the sliding member 26 to limit the sliding member 26 in the axial direction. When the sliding member 26 is in the first position, the sliding member 26 is in contact with the fixture plate 1 as a whole; when the sliding member 26 is in the second position, the sliding member 26 partially extends above the profiling hole 11 and abuts against the lens and is fixed. In this way, the lens coating fixture can fix a lens of a specific thickness.

[0043] Furthermore, in one embodiment, a receiving groove 12 is provided on the jig plate 1 , the receiving groove 12 is communicated with the contoured hole 11 , and the fixing assembly 2 is located in the receiving groove 12 .

[0044] In this embodiment, the fixing member 25 can be a bolt, a screw or a rivet, etc. The fixing member 25 generally includes a column and a head. The diameter of the column of the fixing member 25 is adapted to the width of the slide groove 261, so that the sliding member 26 can move relative to the fixing member 25. The head of the fixing member 25 is pressed on the sliding member 26 to limit the sliding member 26 in the axial direction. When the sliding member 26 is in the first position, the sliding member 26 is entirely located in the receiving groove 12; when the sliding member 26 is in the second position, the sliding member 26 partially extends into the profiling hole 11 and abuts against the lens and is fixed. In this way, the lens coating jig can fix a thinner lens.

[0045] In one embodiment, a protective portion is provided on the end of the stopper 22 that contacts the lens.

[0046] In this embodiment, the protective part protrudes from the main body of the stopper 22. The protective part can be made of elastic materials including but not limited to rubber, elastic plastic or spring steel to protect the lens and prevent the lens from being damaged under pressure.

[0047] In one embodiment, a slot is provided on the inner wall of the contoured hole 11 for clamping a lens.

[0048] In this embodiment, the lens can be initially positioned by providing a slot on the inner wall of the profiling hole 11. It is understandable that a stopper can also be provided on the inner wall of the profiling hole 11, or the profiling hole 11 can just hold the lens, so as to position and initially fix the lens to prevent the lens from falling off the jig.
