Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for optical lens surface precision testing, and in particular to an optical lens surface precision testing bracket device. Background Technology

[0002] Optical lenses require surface precision inspection, and during the inspection process, the optical lenses need to be kept stable above the inspection head. Current technologies generally require auxiliary structures to place the optical lenses and ensure their stability. For example, support brackets are used, with multiple support heads (which can be made of silicone to avoid scratching the optical lenses) providing support points, thus stabilizing the lenses. However, in practice, some optical lenses are large while others are small, requiring frequent replacement of the support brackets. Multiple support brackets are needed, and replacements also delay the overall process. Furthermore, care must be taken to prevent the optical lenses from falling and impacting the inspection head below, which could damage both the lenses and the inspection head. Therefore, the overall time consumption is significantly increased, ultimately failing to improve overall efficiency. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an optical lens surface precision testing bracket device, which solves the problem that the overall time consumption in existing technologies is too long, resulting in no improvement in efficiency.

[0004] According to an embodiment, an optical lens surface precision inspection bracket device is provided, comprising a fixed ring, a support net fixedly disposed within the fixed ring, a through frame located at the center of the fixed ring on the support net, at least three adjustment holes equidistantly arranged around the fixed ring, adjustment posts connected to the adjustment holes, and multiple crossbars corresponding to each adjustment post. Each crossbar has a perforation along its length, passes through the perforation, and an adjustment ring detachably connected to the adjustment post to press against the crossbar. One end of each crossbar extends toward the through frame and is fixedly attached to an upwardly extending support head. In this solution, the crossbars can be adjusted relative to the through frame, allowing the support head on the crossbar to accommodate optical lenses of multiple sizes. Simultaneously, the support net can hold the optical lenses, preventing them from accidentally falling and colliding with the inspection head below. Therefore, the overall process can be faster and less time-consuming, thus solving the problem of long overall time consumption and lack of efficiency improvement in the prior art.

[0005] Furthermore, the fixing ring includes an upper half ring and an opposite lower half ring, the upper half ring and the lower half ring are connected by multiple connecting posts and the outer periphery of the net is sandwiched between the upper half ring and the lower half ring.

[0006] Furthermore, the inner ring of the lower half of the circle is equipped with a receiving platform, and the outer perimeter of the supporting net is inserted into the receiving platform.

[0007] Furthermore, the adjusting hole includes a through hole section on the upper half of the circle and a blind hole section on the lower half of the circle. The adjusting pin is threadedly engaged with both the through hole section and the blind hole section, and the adjusting ring is threadedly engaged with the adjusting pin.

[0008] Furthermore, the connecting columns and adjusting columns are spaced apart.

[0009] Furthermore, a pressure ring that can press against the upper half of the ring is also threaded onto the connecting column.

[0010] Furthermore, multiple support feet are fixed on the bottom surface of the lower half of the ring.

[0011] Compared with the prior art, the present invention has the following beneficial effects: The support head is mounted on a crossbar, and the crossbar can be adjusted relative to the fixed ring to allow for positional adjustment between the support head and the frame. Therefore, the support head on the crossbar can accommodate optical lenses of multiple sizes. At the same time, the set net can hold the optical lenses to prevent them from accidentally falling and colliding with the detection head below. The whole process can be faster and the time consumption is relatively reduced, thus solving the problem that the efficiency cannot be improved due to the long overall time consumption in the existing technology.

[0013] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0014] like Figure 1-3As shown, this embodiment provides an optical lens surface precision testing bracket device, which includes a fixing ring 1. The fixing ring 1 includes an upper half-ring 2 and a lower half-ring 3 that are opposite each other. The upper half-ring 2 and the lower half-ring 3 are detachably connected by multiple connecting posts 4. A support net 5 is pressed between the upper half-ring 2 and the lower half-ring 3. A through frame 6 is provided at the center of the support net 5. Multiple support feet 7 (such as three support feet 7 arranged at equal intervals) are also fixed on the bottom surface of the lower half-ring 3. In use, the fixing ring 1 is placed around the outer periphery of the testing head, and the support feet 7 surround it. Around the outer periphery of the detection head, the through frame 6 is located directly above the detection head. Furthermore, at least three adjustment holes, each including a through-hole section 8 and a blind-hole section 9, are respectively provided on the upper half-circle 2 and the lower half-circle 3. That is, the through-hole section 8 is located on the upper half-circle 2, and the blind-hole section 9 is located on the lower half-circle 3. These are also threadedly connected to adjustment posts 10 (the connecting post 4 can also be threaded). A crossbar 11 is also provided, with slots 12 along its length. One adjustment post 10 corresponds to one crossbar 11, and the crossbar 11 passes through the slots 12. A crossbar 11 and an adjusting column 10 are locked in relative position by an adjusting ring 13 (the adjusting ring 13 and the adjusting column 10 are threaded together). One end of the crossbar 11 extends toward the through frame 6 and is also fixed with a support head 14. The relative position of the support head 14 can be adjusted by the relative position of the crossbar 11 and the adjusting column 10, so that the support head 14 can accommodate optical lenses of multiple sizes, making adjustment more convenient and requiring no additional equipment. At the same time, the net 5 can also hold the optical lens to prevent it from falling and colliding with the detection head below (the net 5 can also be made of plastic, which can reduce the impact compared to metal and avoid greater damage to the optical lens). Therefore, the overall operation can be carried out faster and the time consumption is relatively reduced, thus solving the problem that the overall time consumption in the prior art is long and the efficiency cannot be improved. Furthermore, the support head 14, similar to that in the prior art, can be made of silicone and can directly contact the optical lens to avoid scratching the optical lens.

[0015] like Figure 1-4 As shown, an inlet platform 15 is provided in the inner ring of the lower half ring 3. The outer periphery of the net 5 abuts against the inlet platform 15. The upper half ring 2 and the lower half ring 3 are locked by the connecting post 4, so that the net 5 can be fixed on the fixing ring 1. At the same time, the setting adjustment post 10 also serves to connect the upper half ring 2 and the lower half ring 3. Furthermore, the connecting post 4 and the adjustment post 10 are set at intervals, such as three of them. A pressure ring 16 that can press on the upper half ring 2 is also threaded on the connecting post 4, which makes the upper half ring 2 and the lower half ring 3 more stable. Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
