Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a lens coating layer thickness detection device. Background Technology

[0002] Optical glass is made by mixing high-purity oxides of silicon, boron, sodium, potassium, zinc, lead, magnesium, calcium, barium, etc., according to a specific formula, melting them at high temperature in a platinum crucible, stirring them evenly with ultrasound to remove air bubbles, and then slowly cooling them for a long time to prevent internal stress from forming in the glass block. After cooling, the glass block must be measured by optical instruments to check whether its purity, transparency, uniformity, refractive index, and dispersion rate meet the specifications. The coating layer on the optical lens needs to be inspected using a thickness gauge to determine whether the lens meets the standards. However, when inspecting lenses with current thickness gauges, the operator must first place a lens on the support platform, then run the thickness gauge to inspect the lens, and then stop the machine. The operator then removes the lens and places another lens to be inspected. This repeated placement and removal of lenses requires a long downtime, making the operation cumbersome and reducing the efficiency of inspecting the thickness of the lens coating layer. Utility Model Content

[0003] This utility model discloses a lens coating thickness detection device, which solves the problem that the operation method of placing a lens on the carrier platform for detection, then removing the lens and placing another lens to be tested requires a long downtime, is cumbersome, and reduces the efficiency of lens coating thickness detection.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0005] A lens coating thickness measuring device includes a worktable with a rotatable turntable. A set of support plates is fixed on the outer ring surface of the turntable. A set of placement holes are opened on the support plates. A baffle for sealing the placement holes is provided at the bottom of the support plates. A connecting frame is provided above the worktable, and a thickness gauge that can pass through the set of placement holes on a support plate in sequence is provided in the connecting frame.

[0006] Compared with the prior art, the present invention has the following beneficial effects:

[0007] A set of lenses can be placed in a set of placement holes on a carrier plate. Then, the turntable is rotated so that the carrier plate is positioned below the thickness gauge. As the thickness gauge passes over the set of lenses and inspects them, other lenses to be inspected can be placed in placement holes on another carrier plate adjacent to the one where the lenses were previously placed. This allows for faster sequential inspection of lenses without stopping the machine during loading or unloading, thus improving inspection efficiency. Attached Figure Description

[0012] The specific content of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0013] like Figure 1 , Figure 2 and Figure 3As shown, this utility model provides a lens coating thickness detection device, including a worktable 1, a rotatable turntable 2 on the worktable 1, a set of support plates 3 fixed on the outer ring surface of the turntable 2, a set of placement holes 31 opened on the support plates 3, and a baffle 4 for sealing the placement holes 31 at the bottom of the support plates 3; a connecting frame 6 is provided above the worktable 1, and a thickness gauge 5 is provided in the connecting frame 6 that can pass through the set of placement holes 31 on a support plate 3 in sequence. The operator can place the lens in a set of placement holes 31 on a carrier plate 3, so that the baffle 4 at the bottom of the carrier plate 3 supports the lens. Then, the turntable 2 is rotated, so that the carrier plate 3 moves the lens directly under the thickness gauge 5 (the thickness gauge 5 can be an optical film thickness tester). When the thickness gauge 5 passes over a set of lenses and tests them, another lens to be tested can be placed in the placement hole 31 on a carrier plate 3 adjacent to the one on which the lens was previously placed. This way, after the lens on the previous carrier plate 3 has been tested, the turntable 2 rotates (the turntable 2 can rotate clockwise or counterclockwise), so that the lens on the other carrier plate 3 adjacent to the one on which the lens was previously placed can be quickly moved under the thickness gauge 5 for testing. The operator can then unload the tested lens and place the lens to be tested, thus improving the lens testing efficiency.

[0014] like Figure 1 , Figure 2 and Figure 3 As shown, two symmetrically distributed electric telescopic rods 32 are fixed on the support plate 3. Moving strips 33 are fixed to the telescopic ends of the electric telescopic rods 32. Abutment plates 34 located within placement holes 31 are fixed to the opposite faces of the two moving strips 33. Two grooves adapted to the abutment plates 34 are formed within the placement holes 31. The bottom of the abutment plate 34 contacts the top of the baffle plate 4. When the lens is placed in the placement hole 31 on the support plate 3, the two electric telescopic rods 32 on the support plate 3 are activated, causing the two moving strips 33 to move closer together and contact the lens, thus fixing the lens and preventing it from moving freely. The two abutment plates 34 within a single placement hole 31 can move closer or further apart to fix lenses of different sizes, improving the applicability of this device.

[0015] like Figure 1 and Figure 2As shown, the baffle 4 is slidably connected to the bottom of the support plate 3. The support plate 3 is provided with a first automatic telescopic rod 41 for driving the baffle 4 to move and open the bottom of the placement hole 31. There are two baffles 4 at the bottom of the support plate 3, and the contact surfaces of the two baffles 4 are opposite to the axis of the placement hole 31. There are also two first automatic telescopic rods 41 on the support plate 3. The telescopic ends of the two first automatic telescopic rods 41 are respectively connected to the opposite sides of the two baffles 4 through connecting rods. After the lens is inspected and the support plate 3 is moved away from under the thickness gauge 5, the first automatic telescopic rod 41 can be activated to move the two baffles 4 away from each other and open the bottom of the placement hole 31, so that the lens can fall downward into the external collection frame, improving the efficiency of lens unloading and eliminating the need for manual unloading one by one by the staff.

[0016] like Figure 1 As shown, a second automatic telescopic rod 8 is fixed on the workbench 1. A movable plate 81 is fixed to the telescopic end of the second automatic telescopic rod 8. A placement plate 82 for supporting an external collection frame is slidably connected to one side of the movable plate 81. A fixing block 9 is fixed on the movable plate 81. A screw 91 is threadedly connected to the fixing block 9. One end of the screw 91 is rotatably connected to the placement plate 82. An external collection frame can be placed on the placement plate 82. After the inspected lens moves above the placement plate 82 along with the carrier plate 3, the two baffles 4 at the bottom of the carrier plate 3 can be moved away from each other so that the lens in the placement hole 31 can fall directly into the external collection frame. The external collection frame is filled with sponge, which can effectively protect the lens falling downwards. When the lens in the placement hole 31 on one carrier plate 3 has been unloaded, and it is necessary to unload the lens in the placement hole 31 on another carrier plate 3 that has moved directly above the placement plate 82, the second automatic telescopic rod 8 can be activated to drive the moving plate 81 to move, so that the lens in the placement hole 31 on the carrier plate 3 does not correspond to the lens in the external collection frame, so that the lens falling downwards is staggered from the lens in the external collection frame, avoiding collision between the falling lens and the lens in the external collection frame. Alternatively, the placement plate 82 can be moved up or down by rotating the screw 91 to adjust the height of the external collection frame.

[0017] like Figure 1As shown, a motor 21 is fixed on the workbench 1. The shaft of the motor 21 is fixed to the turntable 2 via a rotating rod. A battery 22 is fixed on the turntable 2. The turntable 2 is located between the placement plate 82 and the connecting frame 6. After starting the motor 21, the rotating rod can drive the turntable 2 to rotate clockwise or counterclockwise. The battery 22 can supply power to the electric telescopic rod 32 and the first automatic telescopic rod 41. There are at least four support plates 3 in a set. The lens on the support plate 3 located on the back of the turntable 2 is directly below the thickness gauge 5. The thickness gauge 5 can detect the lens on the support plate 3. After the lens on the support plate 3 is detected, when the support plate 3 is directly above the placement plate 82, the lens on the support plate 3 can be unloaded.

[0018] like Figure 1 As shown, a support frame 7 is fixed on the workbench 1, and a connecting frame 6 is located inside the support frame 7. A hydraulic rod 71 with its telescopic end connected to the connecting frame 6 is fixed on the support frame 7. A lead screw 61 is rotatably connected inside the connecting frame 6, and a moving block 62 connected to the top of the thickness gauge 5 is threaded onto the lead screw 61. The moving block 62 is slidably connected to the connecting frame 6. The support frame 7 is L-shaped. Activating the hydraulic rod 71 can move the connecting frame 6 downwards to adjust the height of the thickness gauge 5. The connecting frame 6 is U-shaped. A servo motor (not shown in the figure) with a rotating shaft fixed to one end of the lead screw 61 is fixed on one side of the connecting frame 6. Activating the servo motor can drive the lead screw 61 to rotate, causing the moving block 62 to move the thickness gauge 5 forward or backward. Figure 1 (The orientation shown in the image).

[0019] like Figure 2 As shown, a rubber pad 35 is fixed to the side of the abutment 34 used to hold the lens against it. The rubber pad can protect the lens and prevent the lens from being scratched or damaged when the abutment 34 comes into contact with the lens.

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.
