[0002] When gluing small-sized lenses, in order to ensure the concentricity of the two lenses, for example, when gluing a concave lens and a convex lens, the two lenses are usually placed on a special tooling, the upper end of the main body of the special tooling has a neck, and the top of the neck is provided with a groove for placing the lens, and the lens can rotate in the groove. During the gluing operation, the tooling with the lens is placed under the eccentricity meter, and then the lens on the top of the special tooling is rotated to observe the eccentricity of the lens, and adjustments are made during the continuous rotation process until it meets the requirements.

[0003] However, in order to facilitate the rotation of the lens, the groove on the special tooling is relatively shallow, and its ability to limit the lens is limited. Therefore, during manual operation, the lens often comes out of the groove due to excessive force, and the lens needs to be repositioned and adjusted. Summary of the invention

[0006] Further in the above technical solution, a threaded section is provided at the lower end of the limiting rod, an internal thread matching with the threaded section is provided in the insertion hole, and the limiting rod is connected and matched with the insertion hole through threads.

[0007] In addition, a floating limit ring is slidably sleeved on the lower end of the neck in the vertical direction, and the floating limit ring is used to contact and cooperate with the bottom end of the limit rod.

[0008] In a specific structure, the floating limit ring is threadedly connected with the lower end of the neck, and the height position of the floating limit ring can be adjusted by rotating the floating limit ring.

[0009] Furthermore, the bottom of the floating limit ring is further pressed against a spring sleeved on the lower end of the neck, and the other end of the spring is connected to the tooling body.

[0011] Wherein, the limiting groove is in a semi-arc shape matched with the limiting rod, and the insertion hole is a semicircular hole, and the insertion hole and the limiting groove form a full circle.

[0012] The tooling assembly for eccentricity measurement and positioning of the embodiment of the utility model effectively solves the problem that the lens is easy to disengage from the groove during the adjustment process by introducing the design of the limit rod; specifically, the setting of the limit rod can provide necessary support and limit when the lens is rotated, preventing the lens from slipping due to improper operation.

[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: See Figure 1-4 , a fixture assembly for measuring and positioning eccentricity. This fixture assembly is mainly used to place small-sized lenses, for example, lenses with a diameter range of 5-10mm, and measure the eccentricity of the two lenses during the gluing process. The gluing of the concave and convex lenses is an important process step in the lens assembly production. During the gluing process, glue is usually used to overlap the gluing surfaces of the concave lens and the convex lens. In order to ensure the accuracy and quality of the gluing, a series of optical detection instruments are required to detect the eccentricity of the lens before gluing.

[0021] The tool assembly of the present application includes a tool body 100 for placing a lens, the upper end of the tool body 100 has a neck 101, the top of the neck 101 is provided with a groove 102 for placing the lens, and the lens can rotate in the groove 102. Figure 1 The groove 102 is relatively shallow to ensure that the lens placed therein can rotate smoothly when measuring the eccentricity under an optical microscope.

[0022] In this embodiment, a circle of fixing ring 111 is arranged on the neck 101 along its circumference, and the fixing ring 111 is provided with a plurality of insertion holes 112 around the neck 101, and the insertion holes 112 are used to place the limiting rod 200. When the limiting rod 200 is located in the insertion hole 112, the top end of the limiting rod 200 can extend to the outside of the groove 102, and the outer periphery of the limiting rod 200 is flush with the outer edge of the groove 102; when measuring, the lens is placed in the groove 102, and the lens is usually cylindrical. The limiting rod 200 is located on the side of the lens, which can play a good limiting role in the process of rotating the measuring lens, and prevent the lens from being separated from the groove 102 due to excessive force when rotating; to ensure the limiting effect, at least two or more limiting rods 200 are placed. Exemplarily, three limiting rods 200 can be set, and the three limiting rods 200 can be arranged in the semicircle of the lens. In actual use, they are appropriately increased or decreased according to the limiting requirements.

[0023] Different types of lenses have different thicknesses. For example, when a lens with a larger thickness rotates the deflection measuring core, in order to ensure the limiting effect, the height of the limit rod 200 can be increased. In this embodiment, a threaded section is provided at the lower end of the limit rod 200, and the insertion hole 112 has an internal thread that matches the threaded section. The limit rod 200 is connected and matched with the insertion hole 112 through threads. Therefore, the limit rod 200 can be rotated to adjust its extended height.

[0024] Example 2: Figure 1-2 As shown, a floating limit ring 201 is slidably sleeved on the lower end of the neck 101 in the vertical direction, and the floating limit ring 201 is used to contact and cooperate with the bottom end of the limit rod 200 .

[0025] Specifically, the floating limit ring 201 is threadedly connected with the lower end of the neck 101 , and the height position of the floating limit ring 201 can be adjusted by rotating the floating limit ring 201 .

[0026] When installing and adjusting the limit ring 201 in the insertion hole 112, the bottom end of the limit ring 201 is uniformly adjusted until it contacts the floating limit ring 201 to ensure that the extension heights of the limit rods 200 are consistent, avoiding the phenomenon of inconsistent limit effects when placing the lens.

[0027] In addition, the bottom of the floating limit ring 201 is further pressed against the spring 202 mounted on the lower end of the neck 101, and the other end of the spring 202 is connected to the tooling body 100; the threaded connection method of the floating limit ring 201 may become loose, and by arranging a spring 202 at its bottom to tighten it to the thread on the neck 101, it is beneficial to improve its stability.

[0028] Example 3: Figure 1 , 2 As shown in Figure 4, in order to limit the axial direction of the limiting rod 200 and improve its stability, limiting grooves 113 are respectively opened in the vertical direction on the circumference of the neck 101 corresponding to the respective sockets 112 of the fixing ring 111, and the limiting grooves 113 are used to align with the limiting rod 200.

[0029] The limiting groove 113 can be closely matched with the limiting rod 200 to limit the movement of the limiting rod in directions other than rotation, thereby ensuring that the limiting rod can remain stable during use and will not become loose or shifted due to external factors.

[0030] At the same time, the semi-arc shape design of the limiting groove 113 enables the limiting rod 200 to be easily aligned and matched, which not only ensures the convenience of installation, but also ensures the tightness of the fit.

[0031] Specifically, the limiting groove 113 is in a semi-arc shape that matches the limiting rod 200, and the insertion hole 112 is a semicircular hole. The insertion hole 112 and the limiting groove 113 form a whole circle, so that when the limiting rod 200 is screwed into the insertion hole 112, the side wall of the limiting rod 200 can be simultaneously inserted into the limiting groove 113 to limit it.

[0032] 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.
