Description

Technical Field

[0001] This utility model belongs to the field of testing tooling technology, specifically relating to a precision testing tooling for large-diameter cylindrical doped glass surfaces. Background Technology

[0002] In fields such as optics, display technology, medical devices, and energy, doped glasses can be processed into lenses, prisms, and optical fibers for photography, microscopes, and laser equipment. They also have wide applications and high demand in optical glass used in liquid crystal displays (LCDs), organic light-emitting diodes (OLEDs), and other displays. In practical testing, laser interferometers are typically used to inspect the surface accuracy of large-diameter cylindrical doped glasses.

[0003] When the diameter of the doped glass to be tested is larger than that of the laser interferometer, the usual testing method is to divide the large-diameter doped glass into several regions. After testing one region, the doped glass is rotated to the next region, and the surface accuracy is tested separately. Finally, the test results of several regions are stitched together using analysis software to obtain the overall surface accuracy. Because large-diameter cylindrical doped glass has a large mass, when using the above method, the glass relies entirely on the operator to manually rotate it on the platform and then fix it with two reference blocks. Rotating the doped glass not only causes inconvenience, is time-consuming and labor-intensive for the laser interferometer operator, but also carries the risk of collision damage to the doped glass and the laser interferometer. Furthermore, the operator cannot maintain a consistently uniform force during rotation, and the laser interferometer will automatically adjust if the stage is uneven. This rotation operation also wears down the precision pneumatic worktable of the laser interferometer, reducing its lifespan over time. Utility Model Content

[0030] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, so as to better understand the purpose, features and advantages of the present invention. It should be understood that the embodiments shown in the drawings are not intended to limit the scope of the present invention, but are only for illustrating the essential spirit of the technical solution of the present invention.

[0031] In the following description, certain specific details are set forth for the purpose of illustrating various disclosed embodiments in order to provide a thorough understanding of the various disclosed embodiments. However, those skilled in the art will recognize that embodiments may be practiced without one or more of these specific details. In other instances, well-known apparatuses, structures, and techniques associated with this application may not have been shown or described in detail to avoid unnecessarily obscuring the description of the embodiments.

[0032] Throughout this specification, references to "an embodiment" or "an embodiment" indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least one embodiment. Therefore, the appearance of "in an embodiment" or "an embodiment" in various places throughout the specification does not necessarily refer to the same embodiment. Furthermore, a particular feature, structure, or characteristic may be combined in any manner in one or more embodiments.

[0033] In the following description, in order to clearly demonstrate the structure and working method of this utility model, a number of directional terms will be used. However, terms such as "front", "back", "left", "right", "outside", "inside", "outward", "inward", "up", and "down" should be understood as convenient terms and not as limiting terms.

[0034] Reference Figure 1 and Figure 2This utility model provides a large-diameter cylindrical doped glass surface precision testing fixture, which includes a testing frame, two baffles 1 and two rotating parts 2.

[0035] The baffle 1 has an inverted U-shaped structure. Two baffles 1 are arranged opposite each other on the testing frame at a preset distance along a first direction. The opposite surfaces of the two baffles 1 are open, thus forming a space to accommodate the large-diameter doped glass product 4 to be tested. The distance between the two baffles 1 can be determined according to the specifications of the large-diameter doped glass product 4 to be tested, so that the two baffles 1 can restrict the two sides of the large-diameter doped glass product 4 to be tested without affecting its rotation.

[0036] Two rotating parts 2 are arranged side by side on the testing frame along the first direction. The two rotating parts 2 are located between two baffles 1. The rotating parts 2 have a rotating shaft 21 that supports the large-diameter doped glass product 4 to be tested. The axis of the rotating shaft 21 is the second direction, which is a horizontal direction perpendicular to the first direction. The rotating shaft 21 can rotate around its axis.

[0037] Reference Figure 2 When the first direction is left and right, the second direction is front and back.

[0038] When using this utility model, refer to Figure 1 The large-diameter doped glass product 4 to be tested is placed on the rotating shaft 21, with its sides confined within baffles 1. Once one area of ​​the large-diameter doped glass product is tested, the rotating shaft 21 is driven to rotate, moving the large-diameter doped glass product 4 to the next testing area. The baffles 1 serve as a safety measure during product rotation, giving operators time to react in case of tipping, further reducing risk.

[0039] In one embodiment, the testing frame includes two support plates 31, the length direction of the support plates 31 is a first direction, the two support plates 31 are arranged side by side between two baffles 1 along a second direction, the rotating member 2 is disposed on the two support plates 31, and the rotating shaft 21 spans between the two support plates 31.

[0040] In one embodiment, the support plate 31 is provided with a relief groove 311, and the rotating shaft 21 passes through the relief groove 311.

[0041] Preferably, the top surface of the clearance groove 11 is an open structure.

[0042] In one embodiment, the rotating shaft 21 is connected to the support plate 31 by a support bearing to facilitate the stable rotation of the rotating shaft 21.

[0043] In one embodiment, the top surface of the support plate 31 is a downwardly concave arc-shaped surface 312. This reduces contact between the support plate 31 and the large-diameter doped glass product 4 being inspected when it rotates.

[0044] In one embodiment, the testing frame further includes a base 32, a bottom plate 33, and a reinforcing plate 34.

[0045] The base plate 33 is mounted on the base 32, and the baffle 1 is mounted on the base plate 33. The reinforcing plate 34 is mounted on the base plate 33, and the support plate 31 is mounted on the reinforcing plate 34.

[0046] In one embodiment, the base 32 is a rectangular frame structure, the bottom plate 33 and the reinforcing plate 34 are both horizontal planar plates, and the support plate 31 is a vertical planar plate.

[0047] In one embodiment, the rotating component 2 includes a motor 22, which is mounted on the testing frame. The motor shaft of the motor 22 is connected to one end of the rotating shaft 21, and the rotating shaft 21 is driven to rotate by the motor 22.

[0048] When the testing frame has a support plate 31, the motor 22 is mounted on the support plate 31.

[0049] This utility model device has a simple structure and is easy and flexible to operate. Compared with manual rotation by the operator, it can make the rotation of the large-diameter doped glass product 4 under test more stable, reducing the risk of damage to the glass and laser interferometer. The operator can control the rotation of the product through any motor 22, so that the product stops rotating at a designated position, making the testing of the large-diameter doped glass product 4 more efficient and convenient.

[0050] In one embodiment, reference is made to Figure 3 The rotating component 2 is a motor-driven roller component, which includes two rollers 23 and two roller bearings 24.

[0051] The roller 23 has a ring structure with a hole in the middle. A roller bearing 24 is installed in the hole. The two rollers 23 are respectively sleeved on both sides of the rotating shaft 21 through the roller bearing 24. The rotating shaft 21 between the two rollers 23 supports the large-diameter doped glass product 4 to be tested.

[0052] After the large-diameter doped glass product 4 to be tested is placed on the rotating shaft 21, there are two rollers 23 on both sides below the large-diameter doped glass product 4 to be tested. The rollers 23 do not rotate with the rotating shaft 21. Therefore, the rollers 23 can be used as a limiting structure to limit the rolling large-diameter doped glass product 4 to be tested, and further prevent the large-diameter doped glass product 4 to be tested from tipping over when rotating.

[0053] This invention makes the rotation of the large-diameter doped glass product 4 to be tested more stable by setting up a motor-driven roller component.

[0054] In one embodiment, the two ends of the rotating shaft 21 extend from two roller bearings 24. One end of the rotating shaft 21 is connected to the motor shaft of the motor 22, and the other end of the rotating shaft 21 is mounted on the testing frame through a support bearing.

[0055] When the testing frame has a support plate 31, the other end of the rotating shaft 21 is mounted on the support plate 31 via a support bearing.

[0056] In one embodiment, the large-diameter cylindrical doped glass surface precision inspection fixture also includes an operation button, which is connected to the control terminal of the motor 22 via a control circuit.

[0057] In use, place the large-diameter doped glass product 4 to be tested on the rotating shaft 21, press the operation button to make the motor 22 work, and after the large-diameter doped glass product 4 is rotated to the next testing area, release the operation button to start testing the testing area.

[0058] In this embodiment, the control circuit adopts a control circuit that can drive the motor 22 to rotate, which can be a logic control circuit, a PLC control circuit, or a microcontroller control circuit, etc.

[0059] The preferred embodiments of this utility model have been described in detail above. However, it should be understood that after reading the above teachings, those skilled in the art can make various alterations or modifications to this utility model. These equivalent forms also fall within the scope defined by the appended claims.
