Description

Technical Field

[0001] The present invention relates to a field, and in particular to an optical lens testing device. Background Art

[0002] In the field of camera manufacturing, the airtightness of the lens is a crucial indicator, which is directly related to the imaging quality and service life of the lens. Therefore, airtightness testing of camera lenses is an indispensable part of the production process.

[0003] In the prior art, the equipment for air tightness test of optical lenses includes an air tightness tester with inflation and deflation functions, a sealing fixture for accommodating optical lenses, and a tooling for controlling the opening and closing of the fixture. When conducting an air tightness test of an optical lens, the optical lenses need to be placed one by one in the fixture on the tooling, and the fixture is driven to close by the moving part of the tooling. After the steps of inflation, pressure maintenance, testing, deflation, etc., the test results are obtained, and then the fixtures are separated from each other, and the staff takes out the tested optical lenses one by one from the fixture, and then puts in other optical lenses to be tested, and repeats the above steps.

[0004] With respect to the above-mentioned related technologies, the steps of inflation, pressure maintenance, testing, and deflation of existing optical lens testing equipment generally take at least half a minute. The staff cannot effectively use this time to improve the testing efficiency. They need to wait for the completion of the test of one group of optical lenses, and then replace the optical lenses on the fixture one by one before they can carry out the next group of optical lens testing work. When the number of optical lenses to be tested is large or the number of test positions for the optical lenses on the fixture is large, the existing optical lens testing equipment is not easy to efficiently complete the testing work for the optical lenses. In summary, the existing optical lens testing equipment is not easy to efficiently carry out optical lens testing work. Summary of the invention

[0005] Based on this, the purpose of the present invention is to provide an optical lens testing device to solve the technical problem that the existing optical lens testing equipment is not easy to perform optical lens testing work efficiently.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: an optical lens testing device, comprising a base, on which a tooling for testing an optical lens is installed, and also comprising a lower fixture, which is fixedly connected to the base, and the base is respectively provided with a discharge component for placing an optical lens into the lower fixture and a material removal component for taking out the optical lens from the lower fixture on both sides of the lower fixture.

[0007] By adopting the above technical solution, after a test is completed, the driving structure is used to drive the air guide column to rotate, and at the same time, the optical lenses on each position in the lower fixture are replaced, so that the next optical lens test can be carried out directly. During the optical lens test, the staff has sufficient time to replace the optical lens on the carrier, and fully utilizes the time of the optical lens testing equipment to test the optical lens to replace the optical lens, which effectively improves the test efficiency of the optical lens.

[0008] The present invention is further configured such that the base is fixedly connected with a tilting frame tilted toward the lower jig on both sides of the lower jig, and fixed blocks are fixedly connected at both ends of the tilting frame. A hollow air guide column is rotatably connected between the fixed blocks, one end of the air guide column is provided with an air joint, and the other end is connected with a driving motor for driving the air guide column to rotate, and the air guide column is connected with at least one hollow air guide tube at intervals along the axial direction, and the end of the air guide tube is provided with a suction cup for holding the optical lens.

[0009] By adopting the above technical solution, the air guide column connected to the tilting frame is rotated, and after one optical lens test is completed, the optical lenses in the lower fixture are uniformly sucked and rotated out, and then the optical lenses to be tested that are in place in advance are rotated and placed into the lower fixture, and the optical lens test on the next side can be quickly carried out.

[0010] The present invention is further configured such that a second slide rail is provided on the surface of the tilting frame at a position corresponding to the driving motor, a slide plate is slidably connected to the second slide rail, the driving motor is fixedly mounted on the slide plate, a slide groove for sliding of an air guide column is provided on the fixed block along the sliding direction of the driving motor, the air guide column is fixedly connected to a coaxial gear on one side of the slide groove, a rack matching the gear is fixed on one side of the fixed block along the sliding direction of the driving motor, and when the suction cup holds the optical lens located in the lower fixture, the air guide column is located at the bottom end of the slide groove.

[0011] By adopting the above technical solution, the height of the air guide column will gradually decrease during the process of rotating toward the lower jig. When the optical lens is inserted into the lower jig and in place, the rotation state and the sliding state of the air guide column are in place at the same time, so that the air guide column can be closed when the optical lens is placed into the slot of the lower jig to prevent the optical lens from scratching the inner wall of the slot of the lower jig, thereby providing good protection for the optical lens.

[0012] The present invention is further configured such that the base is fixedly connected to a first slide rail on the side of the tilting frame away from the lower fixture, a sliding frame is slidably connected to the first slide rail, a bearing platform with the same number as the optical lenses in the lower fixture is provided at the top of the sliding frame, the bearing platform is used to carry the optical lenses, and a notch for staggering the air guide tube is provided on the side of the bearing platform facing the lower fixture.

[0013] By adopting the above technical solution, the optical lens is carried on the carrier table, and the replacement of the optical lens is completed during the process of testing the optical lens in the closed upper fixture and the lower fixture.

[0014] The present invention is further configured such that after the air guide column rotates, the suction cup at the end of the air guide tube can be located below the support platform, and the suction cup coincides with the axis of the support platform, and the suction cup and the air guide tube will not interfere with the sliding of the sliding frame.

[0015] By adopting the above technical solution, it is prevented that the optical lens on the supporting platform is blocked by the suction cup and knocked off during the sliding process of the sliding frame.

[0016] The present invention is further configured such that the direction of the optical lens located on the support platform is opposite to the direction of the optical lens located in the lower fixture.

[0017] By adopting the above technical solution, the direction of the optical lens can be changed by flipping the air guide tube, so that the lens facing downward on the supporting platform is flipped and kept in an upward state into the lower fixture.

[0018] The present invention is further configured such that one end of the two sliding frames facing the front side of the base is fixedly connected to the connecting frame, and a handle is fixedly connected to the middle of the connecting frame.

[0019] By adopting the above technical solution, after holding the handle, the two sets of sliding frames can be easily pulled out at the same time, so that the optical lens on the supporting platform can be replaced more conveniently.

[0020] The present invention is further configured such that a positioning block for limiting the sliding of the sliding frame is fixedly connected to one end of the first sliding rail facing the back side of the base, and when the sliding frame is limited by the positioning block, the air guide tube is aligned with the optical lens on the lower fixture.

[0021] By adopting the above technical solution, the positioning block is used to position the sliding of the sliding frame, ensuring that the sliding frame can be quickly positioned to the target position each time it is pushed in, making it easier for the suction cup to stably hold the optical lens, thereby further improving the testing efficiency of the optical lens.

[0022] In summary, the present invention mainly has the following beneficial effects:

[0023] 1. The present invention rotatably connects air guide columns on both sides of the lower fixture of the base, and connects the air guide columns to air guide tubes with the same number of optical lens positions on the fixture. After one test is completed, the driving structure is used to drive the air guide columns to rotate, and the optical lenses on each position in the lower fixture are replaced at the same time, so as to directly carry out the next optical lens test. During the optical lens test, the staff has sufficient time to replace the optical lens on the carrier, and fully utilizes the time of the optical lens testing equipment to test the optical lens to replace the optical lens, which effectively improves the test efficiency of the optical lens;

[0024] 2. The present invention arranges inclined tilting frames on both sides of the lower fixture of the base, and arranges a linkage structure that rotates and slides obliquely at the same time on the tilting frames. The height of the air guide column gradually decreases during the process of rotating toward the lower fixture. When the optical lens is inserted into the lower fixture, the rotation state and the sliding state of the air guide column are in place at the same time, so that the air guide column can be closed when the optical lens is placed in the lower fixture to prevent the optical lens from scratching the inner wall of the lower fixture, thereby effectively protecting the optical lens.

[0025] 3. The present invention fixes the support platform for placing the optical lens on the sliding frame. During the optical lens test after the fixture is closed, the staff can slide and pull the sliding frame out to keep the support platform away from the tooling on the base, thereby making it more convenient to replace the optical lens on the support platform, thereby avoiding the problem that the optical lens on the support platform close to the inside of the test equipment is difficult to replace, thereby further improving the testing efficiency of the optical lens.

DETAILED DESCRIPTION

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0037] The following describes an embodiment of the present invention based on its overall structure.

[0038] Embodiment 1

[0039] An optical lens testing device, such as Figure 1-9 As shown, it includes a base 1, on which a tool for testing an optical lens is installed. Specifically, the tool for testing the optical lens includes a lifting plate that can move in a vertical direction, and an upper fixture 3 is fixedly installed on the bottom surface of the lifting plate. It also includes a lower fixture 2. Specifically, a plurality of clamping positions for accommodating an optical lens 13 are arranged in the lower fixture 2. After the lower fixture 2 and the upper fixture 3 move relative to each other and are connected in cooperation, each optical lens 13 is separated from each other into a relatively independent chamber, and the chamber is pressurized and the pressure change state is tested to determine The method for air tightness of optical lens is a prior art, and the present application does not make any improvement to the technology, which will not be elaborated here. The lower jig 2 is fixedly connected to the base 1, and the base 1 is respectively provided with a discharge component for placing the optical lens into the lower jig 2 and a picking component for taking out the optical lens from the lower jig 2 on both sides of the lower jig 2. Specifically, the base 1 is provided with a discharge component for placing the optical lens into the lower jig 2 on one side of the lower jig 2, and a picking component for taking out the optical lens from the lower jig 2 is provided on the other side of the lower jig 2.

[0040] See also Figure 4-7The base 1 is fixedly connected with an inclined frame 8 inclined toward the lower fixture 2 on both sides of the lower fixture 2, and fixed blocks 9 are fixedly connected at both ends of the inclined frame 8. A hollow air guide column 12 is rotatably connected between the fixed blocks 9. An air connector 1204 is provided at one end of the air guide column 12, and a driving motor 11 for driving the air guide column 12 to rotate is connected at the other end. Specifically, the air connector 1204 of the air guide column 12 is connected to the vacuum air pump in the base 1, and is in an air suction state when the optical lens needs to be sucked, so that the suction cup 1203 can stably suck the optical lens, and the air guide column 12 is spaced along the axial direction. At least one hollow air guide tube 1201 is connected. Specifically, the spacing and number of the air guide tubes 1201 are adapted to the spacing and number of the optical lenses in the lower fixture 2. A suction cup 1203 for holding the optical lens is provided at the end of the air guide tube 1201. The air guide column 12 connected to the tilt frame 8 is rotated. After an optical lens test is completed, the optical lenses in the lower fixture 2 are uniformly held and rotated out, and then the optical lenses to be tested that are in place in advance are rotated and placed in the lower fixture 2, and the optical lens test on the next side can be quickly carried out.

[0041] See also Figure 2-9 The base 1 is fixedly connected with a first slide rail 4 on the side of the tilt frame 8 away from the lower fixture 2. Specifically, the two first slide rails 4 are parallel to each other, and a sliding frame 5 is slidably connected to the first slide rail 4. The top of the sliding frame 5 is provided with a bearing platform 501 with the same number as the optical lenses in the lower fixture 2. Specifically, the height of the bearing platform 501 is higher than the height of the suction cup 1203 at the end of the air guide tube 1201 in the vertically upward state. The bearing platform 501 is used to carry the optical lens. A notch for staggering the air guide tube 1201 is provided on the side of the bearing platform 501 facing the lower fixture 2 to prevent the air guide tube 1201 from interfering with the bearing platform 501 when it is rotating. The optical lens is carried by using the bearing platform 501, and the replacement of the optical lens is completed during the testing of the optical lens in the closed upper fixture 3 and the lower fixture 2.

[0042] See also Figure 2-9After the air guide column 12 is rotated, the suction cup 1203 at the end of the air guide tube 1201 can be located below the carrier 501, and the suction cup 1203 coincides with the axis of the carrier 501. After the air guide column 12 is turned over, when the suction cup 1203 at the front end of the air guide tube 1201 faces downward, the optical lens is stably placed in the clamping position of the lower fixture 2, and the suction cup 1203 and the air guide tube 1201 will not interfere with the sliding of the sliding frame 5, thereby preventing the optical lens on the carrier 501 from being affected by the suction cup 1203 during the sliding of the sliding frame 5. 3 is blocked and knocked off, the direction of the optical lens on the carrier 501 is opposite to the direction of the optical lens in the lower fixture 2. Specifically, when the air guide column 12 is not rotated, the suction cup 1203 is vertically upward and located directly below the carrier 501. When the optical lens is placed on the carrier 501, the optical lens contacts the suction cup 1203, and the direction of the optical lens can be changed by flipping the air guide tube 1201, so that the lens facing downward on the carrier 501 is flipped and kept in an upward state until it enters the lower fixture 2.

[0043] Embodiment 2

[0044] An optical lens testing device, such as Figure 1-9 As shown, on the basis of the first embodiment, the difference from the first embodiment is that the surface of the tilting frame 8 is provided with a second slide rail 801 at the position corresponding to the driving motor 11, the second slide rail 801 is slidably connected with the slide plate 10, the driving motor 11 is fixedly installed on the slide plate 10, and a slide groove 901 for sliding the air guide column 12 is provided on the fixed block 9 along the sliding direction of the driving motor 11, and the air guide column 12 is fixedly connected with a coaxial gear 1202 on one side of the slide groove 901, and a fixed gear 1202 is fixed on one side of the fixed block 9 along the sliding direction of the driving motor 11. When the rack 902 cooperates with the gear 1202 and the suction cup 1203 holds the optical lens located in the lower fixture 2, the air guide column 12 is located at the bottom end of the slide groove 901. The air guide column 12 will gradually lower its height during the process of rotating toward the lower fixture 2. When the optical lens is inserted into the lower fixture 2 and in place, the rotation state and the sliding state of the air guide column 12 are in place at the same time, so that the air guide column 12 can be closed when the optical lens is placed in the lower fixture 2 to prevent the optical lens from scratching the inner wall of the lower fixture 2, thereby providing good protection for the optical lens.

[0045] Embodiment 3

[0046] An optical lens testing device, such as Figure 1-9As shown, on the basis of Example 2, the difference from Example 2 is that the ends of the two sliding frames 5 facing the front of the base 1 are fixedly connected to the connecting frame 6. Specifically, the connecting frame 6 is in a horizontal state. When the connecting frame 6 is fixedly connected to the two sliding frames 5, in the process that the two sliding frames 5 slide into place, the connecting frame 6 will not interfere with the lower fixture 2. A handle 7 is fixedly connected to the middle of the connecting frame 6. The handle 7 is convenient for the staff to hold. After holding the handle 7, the two groups of sliding frames 5 can be easily pulled out at the same time, and the optical lens on the carrier 501 can be replaced more conveniently.

[0047] Embodiment 4

[0048] An optical lens testing device, such as Figure 1-9 As shown, on the basis of Example 2, the difference from Example 2 is that a positioning block 401 for limiting the sliding of the sliding frame 5 is fixedly connected to one end of the first slide rail 4 facing the back side of the base 1. Specifically, the positioning block 401 can be set at any position along the length direction of the first slide rail 4. The specific setting position of the positioning block 401 is determined according to the length of the lower fixture 2 in actual conditions, and then the position where the sliding frame 5 needs to be positioned is determined. When the sliding frame 5 is limited by the positioning block 401, the air guide tube 1201 is aligned with the optical lens on the lower fixture 2, and the positioning block 401 is used to position the sliding of the sliding frame 5, ensuring that the sliding frame 5 can be quickly positioned to the target position each time it is pushed in, so that the suction cup 1203 can stably hold the optical lens, further improving the testing efficiency of the optical lens.

[0049] The working principle of the present invention is as follows: after holding the handle 7 to pull out the two sliding racks 5, the lifting platform of the test tooling on the base 1 descends, so that the lower fixture 2 and the upper fixture 3 are closed, and the optical lens is tested. During the test, the staff takes out the optical lenses that have been tested on the bearing platform 501 of one of the sliding racks 5 one by one, and then places the optical lenses to be tested on the bearing platform 501 of the other sliding rack 5 one by one, and then pushes the two sliding racks 5 back to their original positions, effectively utilizing the time when the upper fixture 3 and the lower fixture 2 are closed, and the optical lenses to be tested are placed on the bearing platform 501 of the other sliding rack 5. After the upper jig 3 moves upward and leaves the lower jig 2, the air guide column 12 corresponding to the side of the support platform 501 without the optical lens flips over to hold the optical lens that has been tested in the lower jig 2, then flips over and resets and places it on the unloaded support platform 501. At the same time, the air guide column 12 on the other side holds the optical lens to be tested during the process of taking out the optical lens from the lower jig 2, flips it over and places it in the clamping position of the lower jig 2, and then resets it, so that the replacement of multiple optical lenses in the lower jig 2 can be completed quickly and conveniently, effectively improving the testing efficiency of the optical lenses.

[0050] Although an embodiment of the present invention has been shown and described, this specific embodiment is merely an explanation of the present invention and is not a limitation of the invention. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the present invention. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.
