[0024] In order to make the purpose, technical solutions and advantages of the present application more clear, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, and are not used to limit the present application.

[0025] In the related art, the lens is generally etched by an automatic etching machine, automatic feeding and discharging are realized by the automatic etching machine, the lens is supported by rollers on a plurality of parallel guide rails, and the lens is conveniently moved, but when some small code discs are placed, they may fall into the solution tank below between the two guide rails, and the common support fixture is a whole plane support, the etching liquid is attached to the product surface, and it is difficult to return to the solution tank below in time, thereby affecting the consistency of the product.

[0026] The guide rail is a plurality of parallel shafts, a roller is sleeved on each shaft, and the code disc is supported by the roller, so that the code disc can be quickly moved, and the conventional support fixture is generally glass, so when the small code disc is placed on the glass, some etching liquid is difficult to return to the solution tank below in time through the edge of the glass, thereby affecting the consistency of the product.

[0027] Based on this, please refer to Figure 1 The present application provides a ring piece etching jig, which comprises a base 100 and a boss assembly 200, the base 100 is provided with a plurality of first through holes 100a, the boss assembly 200 is arranged on one side of the base 100, the boss assembly 200 has a bearing surface 200a facing away from the base 100 and a supporting portion 200b for supporting the inner side wall of the ring piece; wherein the bearing surface 200a is arranged in a spaced manner with the base 100, and when the ring piece is located on the bearing surface 200a, the supporting portion 200b is used for supporting the inner side wall of the ring piece.

[0028] It should be understood that the present application is directed to a ring piece (also referred to as a ring code disc 1000), which is stably supported and limited by the bearing surface 200a and the supporting portion 200b of the boss assembly 200, effectively preventing the code disc from being displaced or falling due to vibration or liquid flow during etching, and improving the stability and safety of the etching process.

[0029] The first through holes 100a provided on the base 100 and the spaced arrangement of the bearing surface 200a and the base 100 provide a smooth return channel for the etching liquid. After flowing through the surface of the ring code disc 1000, the etching liquid can quickly flow back into the solution tank below through these through holes, reducing the residence time of the liquid on the product surface, thereby improving the consistency and cleanliness of the product. Since the etching liquid can quickly return, the problem of uneven etching caused by the accumulation of liquid on the product surface is avoided.

[0030] In an embodiment of the present application, please refer to Figure 1The boss assembly 200 comprises a plurality of bosses which are sequentially arranged along the thickness direction of the base 100, wherein the plurality of bosses are coaxially arranged, and the cross-sectional area of the boss gradually increases from the direction away from the base 100 to the direction close to the base 100.

[0031] Along the thickness direction of the base 100, the first boss 210 is adjacent to the base 100, and then sequentially arranged are the second boss 220, the third boss, and the like. The side of the first boss 210 facing the second boss 220 is the bearing surface 200a. When the annular code disc 1000 is located on the first boss 210, the second boss 220 forms the abutting portion 200b. When the annular code disc 1000 is located on the second boss 220, the side of the second boss 220 facing the third boss is the bearing surface 200a, and at this time the third boss forms the abutting portion 200b. Each boss is in a cylindrical shape, and the size of each boss is designed according to the size of the annular code disc 1000, which is not limited herein. By arranging a plurality of bosses, a plurality of code discs within a certain range can be adapted, and the applicability is higher.

[0032] In some embodiments, the plurality of bosses are integrally formed. The integrally formed plurality of bosses ensure the overall structural stability of the boss assembly 200, so that the boss assembly 200 is more solid and durable when bearing the annular code disc 1000, and can withstand greater force and pressure. Of course, the boss assembly 200 can also be integrally formed with the base 100, so that the entire jig structure is more stable.

[0033] The integrally formed technology generally has high manufacturing precision, which can ensure that the size, shape and position of each boss meet the design requirements, and can facilitate the accurate support and limiting of the annular code disc 1000, thereby improving the stability and precision of the etching process. At the same time, integrally forming also reduces the problem of mismatching or interference between adjacent bosses caused by manufacturing errors.

[0034] It should be understood that the boss assembly 200 and the base 100 are made of corrosion-resistant materials, such as alloys, plastics and polymers, and glass and ceramics. When it is an alloy, it can be stainless steel and nickel-based alloy, etc. When it is a plastic and a polymer, it can be polytetrafluoroethylene and polypropylene.

[0035] In another embodiment of the present application, the boss adjacent to the base 100 is connected to the base 100 through a connecting piece (not shown in the figure), that is, the boss assembly 200 and the base 100 are connected in a split manner. In this way, when one of them is damaged, only the boss assembly 200 or the base 100 needs to be replaced.

[0036] The connecting member can be a bolt, a nut, a pin, or other fasteners. It should be understood that the boss (i.e., the first boss 210) adjacent to the base 100 needs to provide a bearing surface 200a for supporting the code disc, so the connecting hole formed in the first boss 210 is a counterbore, so that the bolt cannot protrude from the bearing surface 200a. Similarly, a corresponding counterbore is formed in the base 100, so that the nut matched with the bolt cannot protrude from the lower surface of the base 100, so as not to affect the sliding of the base 100. This connection method is a prior art, and therefore will not be described further in the embodiments of the present application.

[0037] In some other possible embodiments of the present application, the base 100 is provided with a limiting groove (not shown in the figure), and the boss assembly 200 is at least partially located in the limiting groove and abuts against the side wall of the limiting groove.

[0038] That is, the base 100 and the boss assembly 200 are also connected in a split manner, so that when one of them is damaged, only the boss assembly 200 or the base 100 needs to be replaced.

[0039] In addition, the abutment of the boss assembly 200 and the side wall of the limiting groove increases the contact area between the assembly and the base 100, thereby improving the overall stability and making the boss assembly 200 more stable when bearing the gravity of the annular code disc 1000 and the force during etching, and reducing the error caused by shaking or displacement.

[0040] The operator only needs to align the boss assembly 200 with the limiting groove and gently push it in, so as to realize accurate positioning and fixing. This assembly method does not require additional connecting members or complex assembly steps, thereby reducing the assembly difficulty and time.

[0041] Further, in some embodiments of the present application, referring to Figures 1-2 The boss assembly 200 is provided with a second through hole 200c, and the second through hole 200c can communicate with the first through hole 100a, that is, the communication between the second through hole 200c and the first through hole 100a provides a smooth transmission channel for the etching liquid, so that the etching liquid can pass through the boss assembly 200 more quickly and uniformly, thereby improving the fluid transmission efficiency of the entire system.

[0042] In addition, through the design of the second through hole 200c, part of the etching liquid flowing onto the boss assembly 200 can quickly flow into the solution tank below through the second through hole 200c and the first through hole 100a without passing through the annular code disc 1000, thereby further improving the consistency of the product.
