Description

Technical Field

[0001] This utility model relates to the field of CNC machining of optical products, and specifically to a device for double-sided machining of optical products. Background Technology

[0002] In fields such as precision optics and electronic components, it is often necessary to process plastic sheets (such as PC, COC, and acrylic) into optical products with double-sided chamfers. The traditional method of CNC machining double-sided chamfered optical products has the following problems: ① It requires two laminations and two clampings, resulting in low processing efficiency and cumbersome procedures; ② After flipping, the second clamping is prone to product size deviation and positioning errors due to datum offset; ③ During the first-side machining, the tool cannot completely cut through the PE film, requiring the film to be peeled off and re-laminated, which is cumbersome and increases PE film consumption. Utility Model Content

[0003] The purpose of this invention is to provide a simple device for double-sided processing of optical products.

[0004] This utility model provides the following technical solution:

[0005] This utility model proposes a device for double-sided processing of optical products, including a limiting platform. The limiting platform has a plate positioning groove that is consistent with the shape of the initial optical product. The plate positioning groove has a first-sided processing avoidance groove and a second-sided processing positioning groove that is consistent with the shape of the finished optical product. The first-sided processing avoidance groove and the second-sided processing positioning groove are arranged in a cross shape.

[0006] Furthermore, the limiting platform is also provided with a negative pressure adsorption hole, which is located below the intersection center of the first surface machining clearance groove and the second surface machining positioning groove.

[0007] Furthermore, the depth of the plate positioning groove is 80%-90% of the thickness of the optical product.

[0008] Furthermore, the depth of the clearance groove on the first surface is 50%-70% of the thickness of the optical product.

[0009] Furthermore, the first-face machining clearance groove is rectangular, and its size is 1-2 mm larger than the outline of the optical product after the first face machining.

[0010] Furthermore, the depth of the secondary surface machining positioning groove is 50%-70% of the thickness of the optical product.

[0011] Compared with existing technologies, this utility model has a simple structure and is easy to operate. By utilizing the layered groove structure and negative pressure adsorption fixation, CNC double-sided processing can be completed in a single coating, reducing steps such as coating, tearing, and secondary clamping, improving the processing efficiency of double-sided chamfered optical products, and saving PE film usage and manual operation time. At the same time, the secondary processing positioning groove matches the shape of the finished product, reducing the positioning error during secondary processing of the product.

[0017] The present invention will be further described below with reference to the accompanying drawings.

[0018] See Figure 1 In one embodiment of this utility model, an apparatus for double-sided processing of optical products includes a limiting stage 1. The limiting stage 1 has a plate positioning groove 2 that matches the initial shape of the optical product. Below the plate positioning groove 2 are a first-sided processing clearance groove 3 and a second-sided processing positioning groove 4 that matches the shape of the finished optical product. The first-sided processing clearance groove 3 and the second-sided processing positioning groove 4 are arranged in a cross shape. In practical applications, refer to... Figure 2 The initial board 00 is placed in the board positioning groove 2 to initially fix the initial board 00 and limit its horizontal displacement. Next, the initial board 00 undergoes first-side machining. The first-side machining clearance groove 3 allows the cutting tool to penetrate the board and cut through the PE film during machining. See the image for the board after first-side machining. Figure 3 See also Figure 4 After the first surface is processed, the product is flipped over and embedded into the second surface processing positioning groove 4. The groove wall of the second surface processing positioning groove 4 is completely fitted with the first surface of the processed board to avoid datum offset.

[0019] See Figure 1In one embodiment of this utility model, the limiting platform 1 is further provided with a negative pressure adsorption hole 5, which is located below the intersection center of the first surface processing clearance groove 3 and the second surface processing positioning groove 4. In practical applications, the external negative pressure is connected to the lower port of the negative pressure adsorption hole 5 to achieve further adsorption and fixation of the plate 00 and prevent displacement.

[0020] See Figure 2 In one embodiment of this utility model, the depth of the plate positioning groove 2 is 80%-90% of the thickness of the optical product; for example, if the thickness of the plate 00 is 5mm, the thickness of the plate positioning groove 2 is designed to be 4mm, which is conducive to the handling of the plate 00.

[0021] See Figure 3 In one embodiment of this utility model, the depth of the first-side processing clearance groove 3 is 50%-70% of the thickness of the optical product; it accommodates the penetration of the cutting tool through the plate during the first-side processing, further ensuring that the PE film is completely cut through.

[0022] See Figure 3 In one embodiment of this utility model, the first-side processing clearance groove 3 is rectangular, and its size is 1-2mm larger than the outline of the optical product after the first-side processing; it accommodates the cutting allowance after the tool penetrates the plate during the first-side processing, further ensuring that the PE film is completely cut through.

[0023] See Figure 4 In one embodiment of this utility model, the depth of the secondary surface processing positioning groove 4 is 50%-70% of the thickness of the optical product; the depth of the secondary surface processing positioning groove 4 ensures that the plate 00 is firmly embedded and will not move, while the secondary surface (the side opposite to the primary surface) can be processed.

[0024] In practical applications, the external negative pressure is connected to the lower port of the negative pressure adsorption hole. The initial board covered with PE film is placed in the board positioning groove, the negative pressure adsorption is activated to fix it, the first side chamfer is machined by CNC, the tool penetrates the initial board and enters the first side machining clearance groove, cuts through the PE film, and completes the first side machining. The negative pressure is turned off, the product is taken out and flipped, embedded into the second side machining positioning groove, the negative pressure adsorption is activated to fix it, the second side chamfer is machined, and the double-sided machining is completed.

[0025] The embodiments of this utility model are given for the purpose of illustration and description. Although embodiments of this utility model have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting this utility model. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of this utility model.
