It consists of a stable base, a bracket and a measuring instrument. The base supports the entire device to ensure stable measurement; the bracket connects the base and the measuring instrument to ensure that the measuring instrument points stably and accurately to the lens; the measuring instrument is the core measuring component, and its measuring head is designed to penetrate the bracket and extend downward flexibly to directly measure the lens on the base. When measuring, the lens is first accurately inserted into the fixture groove to ensure stability and accuracy, and then the fixture is placed on the base, and the lens is aligned with the measuring head of the measuring instrument for measurement.

[0003] In the above structure, lenses of different sizes need to be matched with fixtures of different sizes. Then, during the measurement process, the fixture is placed directly under the measuring head. During this process, the position of the fixture needs to be accurate. Therefore, when the number of lenses to be measured is large, it is inconvenient to adjust the position of the fixture. Summary of the invention

[0004] In order to solve the above problems, the utility model discloses a multi-station lens measurement auxiliary device.

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.

[0017] 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.

[0018] Example 1: See Figure 1-3 A multi-station lens measurement auxiliary device comprises a base 100, a bracket 101 and a measuring instrument 102 arranged on the bracket 101, wherein a measuring head 121 of the measuring instrument 102 passes downward through the bracket 101 and is arranged toward the base 100, characterized in that: a turntable 200 is rotatably arranged on the base 100, a plurality of ferrules 201 are evenly distributed on the top circumference of the turntable 200, a ferrule 201 has a slot 300 matched with the lens, and the center of any ferrule 201 can be aligned with the center of the measuring head 121. The center of each ferrule 201 can be aligned with the center of the measuring head 121 of the measuring instrument 102 to ensure the accuracy of the measurement. The arrangement of multiple ferrules 201 can place multiple lenses at the same time. After the measurement of a certain lens is completed, the turntable 200 can be rotated to move the lens at the next position to the bottom of the measuring head 121.

[0019] In order to further enhance the positioning accuracy of the turntable 200, limiting grooves 202 are respectively provided on the outer circumference of the turntable 200 corresponding to each ferrule 201, and a limiting block 203 for aligning with the limiting groove 202 is provided on the side of the base 100 corresponding to the turntable 200. The limiting block 203 is set on the base 100 along the radial sliding direction of the turntable 200.

[0020] The limiting block 203 can be precisely aligned with the limiting groove 202 , so that each ferrule 201 can be accurately aligned with the measuring head 121 .

[0021] In addition, a spring 231 is provided at one end of the limit block 203, and the spring 231 acts on the limit block 203, so that the limit block 203 abuts against the limit slot 202. A spring 231 is installed at one end of the limit block 203, and the spring 231 applies force to the limit block 203, so that it always abuts tightly against the limit slot 202. This design increases the stability of the positioning of the turntable 200. When the turntable 200 needs to be rotated, the limit block 203 is pushed outward to disengage the limit block 203 from the limit slot 202.

[0022] The limiting groove 202 is in an arc shape, and the end of the limiting block 203 is a semicircular shape that matches the limiting groove 202. The arc-shaped limiting groove 202 and the semicircular limiting block 203 cooperate with each other to provide a more stable sliding contact surface during the rotation of the turntable 200. The friction resistance and jamming phenomenon during rotation are reduced, so that the turntable 200 can rotate to each station more smoothly.

[0023] Furthermore, the card slot 300 of the card sleeve 201 is in the shape of a circular hole, and the diameters of the card slots 300 of the card sleeves 201 are gradually increased to accommodate lenses of different sizes. The card sleeve 201 is integrated on a turntable 200, and the size of the card slot 300 is gradually increased, which can reduce manufacturing costs and material consumption compared to the solution of manufacturing a fixture for each size of lens separately.

[0024] Example 2: See Figure 3 When the lens is inserted into the card slot 300, it is sometimes difficult to remove due to the large friction force. For this reason, a plug hole 211 is provided at the bottom end of the card sleeve 201, and a push block 212 is provided on the turntable 200 corresponding to the plug hole 211 and slidingly arranged along the radial direction of the turntable 200. The push block 212 can be inserted into the plug hole 211, and the height of the push block 212 is gradually reduced toward one end of the plug hole 211, thereby forming a wedge-shaped surface. By pushing the push block 212 into the plug hole 211, the bottom end of the lens can be pried up to facilitate the removal of the lens.

[0025] The insertion hole 211 passes through the bottom of the ferrule 201, providing space for the subsequent operation of the push block 212. The end of the push block 212 extending into the insertion hole 211 is specially designed to be a wedge-shaped surface, that is, its height gradually decreases. It is convenient for the push block 212 to gradually penetrate into the insertion hole 211. By utilizing the slope of the wedge-shaped surface, when the push block 212 is pushed in, the bottom end of the lens can be gradually pried up.

[0026] In actual operation, when the lens needs to be taken out, the operator only needs to gently push the push block 212 to slide it along the radial direction of the turntable 200 toward the insertion hole 211. As the push block 212 goes deeper, its wedge-shaped surface will gradually contact the bottom end of the lens, and due to the effect of the inclined surface, the lens will be gradually pried up. When the lens is pried up to a certain extent, the operator can easily take the lens out of the card slot 300.

[0027] In addition, in order to ensure the stability and accuracy of the push block 212 during the sliding process, an appropriate guide rail or limit structure may be provided on the turntable 200 to guide the sliding path of the push block 212 .

[0028] 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.
