[0002] Optical lenses need to be tested for thickness during production and processing in order to promptly screen out substandard products. When testing the thickness of optical lenses, a thickness detection device is required.

[0003] The patent with the patent authorization announcement number CN212133517U discloses an optical lens thickness detection device. When the thickness detection device detects, a weight is placed on the weight plate, so that the metal rod moves down, and the upper pressure plate drives the lower pressure plate to contact the top of the optical lens. By observing the laser pen and the scale, the optical lens thickness detection result can be obtained and recorded. The thickness detection device can only measure the thickness of one optical lens at a time. Therefore, when detecting a batch of optical lenses, it is necessary to frequently take and put the optical lenses on the thickness detection device, which makes the working efficiency of the optical lens thickness detection low.

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] It should be noted that the optical lens thickness measuring device described in the utility model is used for but not limited to optical lens thickness detection, etc. For the convenience of explanation, in the utility model, only the application of the optical lens thickness measuring device to optical lens thickness detection is used as an example for explanation, and the principle of applying the optical lens thickness measuring device to other types of equipment is essentially the same as the principle applied to optical lens thickness detection, which will not be described one by one here.

[0029] See also Figure 1 , Figure 1 The schematic diagram of the structure of the optical lens thickness measuring device in one embodiment of the utility model comprises a frame 100, a micrometer 200 and a support assembly 300, wherein the micrometer 200 is mounted on the frame 100. The support assembly 300 comprises a rotating seat 310 and a plurality of trays 320, wherein the rotating seat 310 is rotatably mounted on the frame 100, and the plurality of trays 320 are circumferentially mounted on the rotating seat 310, and the trays 320 are provided with storage slots 321 for placing optical lenses. Among them, the optical lenses in any storage slot 321 can rotate relative to the frame 100 following the rotating seat 310, and the moving track of the optical lenses has a detection position facing the micrometer 200.

[0030] In this embodiment, the optical lenses to be tested are first placed one by one in the storage slots 321 of each tray 320, and each optical lens can be driven to move by rotating the rotating seat 310, so that each optical lens is aligned with the micrometer 200 one by one, and then the thickness of the optical lens can be measured by the micrometer 200. Using the above optical lens thickness measuring device, multiple optical lenses can be placed in each tray 320 at one time, and the thickness of each optical lens can be quickly measured by rotating the rotating seat 310, avoiding frequent placement of optical lenses during the process of measuring the thickness of optical lenses, thereby improving the working efficiency of measuring the thickness of optical lenses.

[0031] In some embodiments, the rotating base 310 defines a plurality of slots 311 corresponding to the plurality of trays 320 , and the trays 320 are embedded in the slots 311 .

[0032] In this embodiment, the tray 320 is embedded in the slot 311 , and the slot 311 can be used to limit the position of the tray 320 , so that the tray 320 is more stably installed on the rotating base 310 .

[0033] Based on the above embodiments, in some of the embodiments, a first screw hole 322 is opened at the bottom end of the tray 320, and a matching hole 312 is opened at the rotating seat 310. A bolt passes through the matching hole 312 and is screwed into the first screw hole 322 to connect the tray 320 and the rotating seat 310 to each other.

[0034] In this embodiment, when the tray 320 is embedded in the slot 311, a bolt is passed through the matching hole 312 and screwed into the first screw hole 322 to connect the tray 320 and the rotating seat 310 to each other, thereby fixing the relative position of the tray 320 and the rotating seat 310 to prevent the tray 320 from moving relative to the rotating seat 310 during the movement of the rotating seat 310, thereby affecting the final detection accuracy.

[0035] In some embodiments, the frame 100 includes a base rod 110 and a slide 120. The slide 120 is provided with a guide hole 121. The guide hole 121 is sleeved on the base rod 110 so that the slide 120 is slidably disposed on the base rod 110, and the slide 120 can stay at any position on its sliding track.

[0036] In this embodiment, since the slide 120 is slidably disposed on the base rod 110 and the slide 120 can stay at any position on its sliding track, the vertical height of the slide 120 can be adjusted, and the micrometer 200 can be calibrated by adjusting the digital height of the slide 120 .

[0037] In some embodiments, the frame 100 further includes a limiting member 130 , which has a first state for limiting the sliding seat 120 from sliding relative to the base rod 110 , and a second state for allowing the sliding seat 120 to slide relative to the base rod 110 .

[0038] In this embodiment, when the vertical height of the slide 120 needs to be adjusted, the limit member 130 can be adjusted to the second state, and then the slide 120 can be slid along the base rod 110. When the slide 120 needs to be fixed, the limit member 130 can be adjusted to the first state.

[0039] On the basis of the above embodiments, in some of the embodiments, the slide seat 120 is provided with a second screw hole 122 connected to the guide hole 121, the limiting member 130 includes a screw button 131, the screw button 131 is screwed into the second screw hole 122, when the limiting member 130 is in the first state, the screw button 131 presses the base rod 110, and when the limiting member 130 is in the second state, the screw button 131 is separated from the base rod 110.

[0040] In this embodiment, when the limiting member 130 is in the first state, the screw button 131 presses against the base rod 110, and the friction between the screw button 131 and the base rod 110 can prevent the sliding seat 120 from moving relative to the base rod 110. When the limiting member 130 is in the second state, the screw button 131 is separated from the base rod 110. Due to the loss of the friction between the screw button 131 and the base rod 110, the sliding seat 120 can slide smoothly relative to the base rod 110.

[0041] In some embodiments, both ends of the base rod 110 have limiting portions 111 , the slide 120 is located between the two limiting portions 111 , and the limiting portions 111 prevent the slide 120 from passing through the limiting portions 111 .

[0042] In this embodiment, under the obstruction of the two limiting portions 111 , the sliding seat 120 can only slide between the two limiting portions 111 , thereby limiting the sliding area of ​​the limiting portions 111 .

[0043] In some of the embodiments, the rack 100 is a metal rack 100 .

[0044] In this embodiment, the frame 100 has sufficient structural strength.

[0045] In some embodiments, a guide wedge surface is formed at the top of the receiving groove 321 .

[0046] In this embodiment, the guide wedge surface can guide the optical lens so as to facilitate placement of the optical lens into the storage groove 321 .

[0047] In some embodiments, the tray 320 defines a notch 323 communicating with the receiving slot 321 .

[0048] In this embodiment, since the tray 320 is provided with a notch 323 connected to the storage slot 321 , an operator can access the optical lens in the storage slot 321 through the notch 323 , so as to facilitate the operation of taking and placing the optical lens.

[0049] In order to better understand the present invention, the following Figures 1 to 3 The technical solution of the utility model is described in detail:

[0050] First, the stopper 130 is switched to the second state, so that the slide 120 can slide along the base rod 110, thereby adjusting the vertical height of the slide 120. When the slide 120 is at a suitable vertical height, the stopper 130 can be adjusted to the first state when necessary, thereby fixing the slide 120. Then, the micrometer 200 is calibrated, and the optical lenses to be tested are placed one by one in the storage slots 321 of each tray 320. By rotating the rotating seat 310, each optical lens can be driven to move, so that each optical lens is aligned with the micrometer 200 one by one, and then the micrometer 200 can be used to measure the thickness of the optical lens. Using the above optical lens thickness measuring device, multiple optical lenses can be placed in each tray 320 at one time, and the thickness of each optical lens can be quickly measured by rotating the rotating seat 310, avoiding frequent placement of optical lenses during the process of measuring the thickness of the optical lenses, thereby improving the work efficiency of measuring the thickness of the optical lenses.
