Description

Technical Field

[0001] The utility model relates to the field of lens manufacturing, in particular to an auxiliary device for facilitating the taking of tiny lenses. Background Art

[0002] When processing the chamfers or edges of small-sized lenses, such as those with a size of several millimeters to several centimeters, fixing the lens is a key step to ensure processing accuracy and avoid damage. In the traditional method, the operator will apply a disposable protective film on the lens, which is used to prevent scratches or other damage to the lens surface during processing. Then, the operator will use a round rod with a similar diameter to dip in glue and then bond and fix the lens on the round rod.

[0003] However, in actual operation, it is very difficult to control the amount of glue applied due to the small surface area of ​​small-sized lenses. Too much glue will not only cause inaccurate positioning of the lens on the round rod, increasing the difficulty of processing, but also the excess glue will overflow and contaminate the area around the lens, increasing the workload and difficulty of subsequent cleaning. In addition, too much glue may also penetrate into the gap between the lens and the round rod, affecting the processing quality, and even in extreme cases, may cause the lens to be scrapped.

[0017] In order to make the purpose, technical solutions and advantages of the utility model clearer, the utility model will be further described in detail below with reference to the accompanying drawings.

[0018] The terms used in the following embodiments are only for the purpose of describing specific embodiments and are not intended to be used as limitations on the present invention. As used in the specification and appended claims of the present invention, the singular expressions "a", "an", "above", "the" and "this" are intended to also include expressions such as "one or more", unless there is a clear contrary indication in the context.

[0019] References to "one embodiment" or "some embodiments" etc. described in this specification mean that one or more embodiments of the utility model include specific features, structures or characteristics described in conjunction with the embodiment. Therefore, the statements "in one embodiment", "in some embodiments", "in some other embodiments", "in some other embodiments", etc. that appear in different places in this specification do not necessarily refer to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized in other ways. The terms "including", "comprising", "having" and their variations all mean "including but not limited to", unless otherwise specifically emphasized in other ways.

[0020] Example 1: Figure 1-4 As shown, an auxiliary device for facilitating the taking of a tiny lens comprises a connecting end 100 and a sleeve 200 connected to the connecting end 100, wherein the connecting end 100 has an end face 101 for bonding with the lens to be processed.

[0021] The pipe sleeve 200 is provided with a liquid storage chamber 201 near the connecting end 100, and the other end of the pipe sleeve 200 corresponding to the liquid storage chamber 201 is provided with a piston 202 and a push rod 203 connected to the piston 202. The center of the end surface 101 is provided with a channel 102 connected to the liquid storage chamber 201 toward the pipe sleeve 200; the liquid storage chamber 201 is used to store glue in advance and can be preset at the factory. The connecting end 100 and the pipe sleeve 200 can be detachably connected by threads. When the connecting end 100 is disassembled in later use, the pipe sleeve 200 can be used alone to absorb glue.

[0022] In a possible implementation, the pipe sleeve 200 is a hollow structure, the push rod 203 is inserted into the pipe sleeve 200 , and one end of the push rod 203 extends to the outside of the pipe sleeve 200 .

[0023] During operation, the connecting end 100 is placed against the surface of the lens to be processed, and the push rod 203 is extended to the outer end of the sleeve 200 by pressing, so as to push the piston 202, squeeze out the glue stored in the liquid storage chamber 201, and reach the end surface 101 through the channel 102 to bond and fix the lens.

[0024] In order to make the glue more evenly cover the surface of the end face 101 when it is squeezed out, a plurality of liquid guide grooves 103 are evenly distributed on the end face 101, one end of each liquid guide groove 103 is connected to the hole 102, and the other end of each liquid guide groove 103 extends to the edge of the end face 101. When the glue flows out of the hole 102, it will be evenly distributed on the entire end face 101 along these liquid guide grooves 103.

[0025] Furthermore, the end surface 101 is recessed inwardly and forms a retaining ring around the connecting end 100. The recessed end surface 101 can contain the squeezed glue and reduce overflow.

[0026] The outer edge of the liquid guiding groove 103 is provided with a chamfer to play a guiding transition role so as to facilitate the glue to flow out to the end surface 101 .

[0027] In this embodiment, the uniform distribution and effective control of glue are achieved by designing the liquid guide groove 103 and the concave end surface 101, thereby improving the bonding quality and efficiency. The precise extrusion of glue is achieved by the cooperation of the push rod 203 and the piston 202, thereby further improving the bonding accuracy.

[0028] Example 2: Figure 2 As shown, the sleeve 200 has a limit mechanism for limiting the axial displacement distance of the push rod 203. This limits the displacement distance when the push rod 203 pulls the piston 202, limits the amount of glue absorbed, and avoids excessive suction and squeezing out too much glue during squeezing.

[0029] In the specific structure, the limiting mechanism includes: a first limiting ring 231 arranged on the push rod 203, and a second limiting ring 232 and a third limiting ring 233 arranged in the sleeve 200, the push rod 203 passes through the second limiting ring 232 and the third limiting ring 233 respectively, the first limiting ring 231 is located between the second limiting ring 232 and the third limiting ring 233, and the outer diameter of the first limiting ring 231 is larger than the second limiting ring 232 and the inner hole diameter of the third limiting ring 233.

[0030] When the push rod 203 moves in the axial direction, the first limiting ring 231 moves between the second limiting ring 232 and the third limiting ring 233. When the first limiting ring 231 moves to contact the second limiting ring 232 or the third limiting ring 233, it will be blocked, thereby limiting the further movement of the push rod 203. In this way, the displacement distance of the push rod 203 can be accurately controlled, thereby controlling the amount of glue sucked and squeezed out.

[0031] One end of the push rod 203 extends out to the outer end of the sleeve 200 and is connected to a pressing head 234 . A spring 204 acts between the pressing head 234 and the sleeve 200 , and the spring 204 acts on the pressing head 234 .

[0032] The function of the spring 204 is to provide a restoring force for the pressing head 234 so that the push rod 203 can automatically return to the initial position after the operator releases the pressing head 234 .

[0033] In this embodiment, by providing a limiting mechanism, the displacement distance of the push rod 203 is accurately controlled, thereby achieving accurate control of the amount of glue sucked and squeezed out.

[0034] By designing the coordination between the spring 204 and the pressing head 234, the automatic resetting function of the push rod 203 is realized, thereby improving the working efficiency and convenience.

[0035] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
