DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0031] A testing device for optical parts production is used to test the thickness of optical lenses by measuring. Figure 1-4 As shown, it includes a base 1 and a fixing part, and the fixing part includes:

[0032] Vertical plate 5: fixed to the top outer wall of the base 1 by bolts;

[0033] Electric cylinder 1 2: It is fixed to the outer wall of one side of the vertical plate 5 by bolts;

[0034] Connecting block 2 16: It is fixed to the output end of electric cylinder 1 2 through a pin;

[0035] Electric cylinder 2 4: It is fixed to the outer wall of one side of the connecting block 2 16 by bolts, and the output end of the electric cylinder 2 4 is fixed to the connecting block 1 13 by a pin, and a suction cup assembly is provided on the surface of the connecting block 13;

[0036] By providing a suction cup assembly, the optical lens can be fixed by adsorption, and by providing electric cylinder 1 2 and electric cylinder 2 4, the position of the vacuum suction cup 15 in four different directions of front, back, left and right can be adjusted, thereby facilitating subsequent thickness testing at different positions on the surface of the optical lens and reducing blind spots in testing.

[0037] Furthermore, the suction cup assembly includes a joint 14 and a vacuum suction cup 15, the vacuum suction cup 15 is embedded in the inner wall of the through hole opened on the surface of the connecting block 13, and the joint 14 is integrally formed on the outer wall of the vacuum suction cup 15;

[0038] By connecting the connector 14 and equipment such as an air pump, when the optical lens is placed on the vacuum suction cup 15, the vacuum suction cup 15 can fix the optical lens by vacuum adsorption, thereby ensuring the stability of the optical lens during movement.

[0039] Furthermore, a bracket 3 is fixed to the top outer wall of the base 1 by bolts, a slide rod 6 is slidably connected to the inner wall of the through hole opened at the top of the bracket 3, a hollow cylinder 11 is threadedly connected to the bottom outer wall of the slide rod 6, and a rolling ball 12 is rotatably connected to the inner wall of the hollow cylinder 11;

[0040] When the thickness of the optical lens needs to be detected, the slide bar 6 is moved upward along the bracket 3 so that the spherical outer wall of the rolling ball 12 fits with the upper surface of the optical lens. By measuring the upward distance of the slide bar 6 at this time, the thickness of the optical lens can be indirectly detected. By setting the rolling ball 12 to be able to roll along the inside of the hollow cylinder 11, the friction between the hollow cylinder 11 and the optical lens can be effectively reduced, thereby protecting the optical lens.

[0041] Furthermore, the top outer wall of the slide bar 6 is fixed with a limit plate 9 by a pin, the circumferential outer wall of the slide bar 6 is sleeved with a spring 10, and the two ends of the spring 10 are respectively fixed to the bottom outer wall of the limit plate 9 and the top outer wall of the bracket 3 by pins;

[0042] The elastic force of the spring 10 can ensure that the slide bar 6 can be automatically reset after the optical lens is removed from the vacuum suction cup 15 after the thickness detection is completed.

[0043] Furthermore, a pointer 8 is fixed to the top outer wall of the limit plate 9 by a pin, and a scale 7 is bonded to the top outer wall of the bracket 3;

[0044] The pointer 8 and the scale 7 can be provided to intuitively display the thickness of the optical lens, making it easy to read the thickness of the optical lens through the scale 7.

[0045] Working principle: When it is necessary to test the thickness of the optical lens, first pull the limit plate 9 upwards and place the optical lens on the top of the vacuum suction cup 15, then connect the joint 14 and the vacuum device to make the vacuum suction cup 15 vacuum absorb the optical lens, and then use the elastic force of the spring 10 to press the rolling ball 12 against the upper surface of the optical lens, read the scale on the scale 7 pointed by the pointer 8 at this time, subtract the reading of the pointer 8 in the initial stage from the reading, so that the thickness of the optical lens can be detected. In the initial stage, the bottom of the rolling ball 12 is flush with the top of the vacuum suction cup 15, and then use the electric cylinder 2 4 and the electric cylinder 1 2 to move the vacuum suction cup 15 and the optical lens in the range of front, back, left and right, so that the thickness of multiple positions on the surface of the optical lens can be detected. If the error between the detected thickness value of the optical lens and the thickness value set by the production standard is within the set range, the thickness of the optical lens meets the production requirements, otherwise the thickness of the optical lens does not meet the production requirements.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
