Description

Technical Field

[0001] This utility model relates to the field of contact lens testing technology, and in particular to a contact lens testing device. Background Technology

[0002] Contact lenses are typically made of soft polymer materials such as hydrogel or silicone hydrogel, and their tensile strength is a key indicator for evaluating the safety and durability of the lenses.

[0003] Currently, the existing technology generally uses a tensile tester to conduct lens tensile tests. Specifically, the lens tensile test is completed by two tensile testers. The tensile testers are equipped with clamps, the lens is picked up by tweezers and taken out of the contact lens solution, so that the two tensile testers can hold the two sides of the lens respectively and stretch the lens to complete the test.

[0004] However, because the lens is made of soft rubber, the edges of the lens will naturally droop when the lens is picked up with tweezers, making it difficult for the tension gauge to hold the lens and thus making it inconvenient to perform tensile tests on the lens. Utility Model Content

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0036] In the description of this embodiment, the terms "upper," "lower," "right," and "left," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0037] Please see Figure 1 and Figure 2 This embodiment provides a contact lens testing device, which includes a stage 1, a first clamping module 2, and a second clamping module 3. The stage 1 is configured to hold the lens to be tested, and the lens extends out of the stage 1 on both sides radially. The first clamping module 2 and the second clamping module 3 are arranged at intervals in the horizontal direction. The first clamping module 2 includes a first carrier block 21 and a first pressing block 22, and the second clamping module 3 includes a second carrier block 31 and a second pressing block 32. The first carrier block 21 and the second carrier block 31 are both flush with the stage 1 and can respectively support the lens extending radially out of the stage 1 on both sides.

[0038] That is, for a lens placed on the stage 1, the middle part of the lens is supported by the stage 1, and the two sides of the lens along its radial direction are supported by the first carrier block 21 and the second carrier block 31 respectively.

[0039] Furthermore, the first pressing block 22 can press one side of the lens along its radial direction against the first carrier block 21, and the second pressing block 32 can press the other side of the lens along its radial direction against the second carrier block 31. Thus, the first pressing block 22 and the first carrier block 21 jointly clamp one side of the lens along its radial direction, while the second pressing block 32 and the second carrier block 31 jointly clamp the other side of the lens along its radial direction. That is, in this embodiment, the lens is supported by the platform 1, the first carrier block 21 and the second carrier block 31, and the first pressing block 22 cooperates with the first carrier block 21 to clamp one side of the lens along its radial direction, while the second pressing block 32 cooperates with the second carrier block 31 to clamp the other side of the lens along its radial direction.

[0040] In addition, the first carrier block 21 is provided with a first pull head 211, and the second carrier block 31 is provided with a second pull head 311. The first pull head 211 is located on the side of the first carrier block 21 away from the second carrier block 31, and the second pull head 311 is located on the side of the second carrier block 31 away from the first carrier block 21. The first pull head 211 and the second pull head 311 respectively hook the first tension gauge (not shown in the figure) and the second tension gauge (not shown in the figure). The first tension gauge and the second tension gauge can pull the first clamping module 2 and the second clamping module 3 to move in opposite directions, thereby stretching the lens and performing a stretching test on the lens.

[0041] Specifically, the first and second force gauges can pull the first clamping module 2 and the second clamping module 3 to move in opposite directions, thereby applying a pulling force to both sides of the lens along its radial direction, and thus performing a tensile test on the lens.

[0042] In summary, in this embodiment, the lens is first placed flat on the stage 1, the first carrier block 21, and the second carrier block 31. Then, the first pressing block 22 presses against one side of the lens along its radial direction, thereby cooperating with the first carrier block 21 to jointly clamp the lens along its radial direction. The second pressing block 32 presses against the other side of the lens along its radial direction, thereby cooperating with the second carrier block 31 to jointly clamp the other side of the lens along its radial direction. This achieves clamping the lens on both sides along its radial direction. Furthermore, in this embodiment, the first tension gauge pulls the first carrier block 21 and the first pressing block 22 to move, and the second tension gauge pulls the second carrier block 31 and the second pressing block 32 to move, thereby performing a tensile test on the lens.

[0043] That is, in this embodiment, the edge of the lens is supported by the first carrier block 21 and the second carrier block 31, and the lens is pressed against the first carrier block 21 by the first pressing block 22 and against the second carrier block 31 by the second pressing block 32, thereby clamping the lens on both sides along its radial direction. Subsequently, the first tensile gauge pulls the first carrier block 21 and the first pressing block 22 to move, and the second tensile gauge pulls the second carrier block 31 and the first pressing block 22 to move, thereby performing a tensile test on the lens. Therefore, this embodiment can easily clamp the lens, thus facilitating the tensile test on the lens.

[0044] Based on the above, the first carrier block 21 is provided with a first support area, and the lens is placed on one side of its radial direction in the first support area, while the second carrier block 31 is provided with a second support area, and the lens is placed on the other side of its radial direction in the second support area. That is, for the lens placed on the stage 1, the middle part of the lens is supported by the stage 1, and the two sides of the lens along its radial direction are respectively located in the first support area and the second support area, and are thus supported by the first carrier block 21 and the second carrier block 31 respectively.

[0045] The first pressing block 22 has a first working position covering the first supporting area and a second working position away from the first supporting area. Correspondingly, the second pressing block 32 has a third working position covering the second supporting area and a fourth working position away from the second supporting area. When the first pressing block 22 is in the second working position and the second pressing block 32 is in the fourth working position, the lens can be placed on the stage 1, the first carrier block 21 and the second carrier block 31.

[0046] When the first pressure block 22 is switched to the first working position, the lens is positioned between the first pressure block 22 and the first carrier block 21 on one side of its radial direction. Moreover, the first clamping module 2 also includes a first locking member 23, which can lock the first pressure block 22 to the first working position and make the first pressure block 22 press against the lens, thereby clamping the lens on one side of its radial direction.

[0047] When the second pressure block 32 is switched to the third working position, the other side of the lens along its radial direction is placed between the second pressure block 32 and the second carrier block 31. Moreover, the second clamping module 3 also includes a second locking member 33, which can lock the second pressure block 32 to the third working position and make the second pressure block 32 press against the lens, thereby clamping the other side of the lens along its radial direction.

[0048] The first locking member 23 includes a first head 231 and a first rod 232. The first rod 232 extends vertically, and a first pressing block 22 is sleeved on the outer periphery of the first rod 232. The first rod 232 can pass through the first pressing block 22 and be screwed to the first carrier block 21, and the first head 231 abuts against the first pressing block 22. That is, in this embodiment, the side of the first rod 232 away from the first head 231 is formed as a first threaded segment 2321. The first locking member 23 can be screwed to the first carrier block 21 through the first threaded segment 2321. When the first rod 232 is screwed to the first carrier block 21, the first pressing block 22 is sleeved on the outer periphery of the portion of the first rod 232 located between the first head 231 and the first threaded segment 2321. The first head 231 abuts against the first pressing block 22. At this time, the first locking member 23 locks the first pressing block 22 to the first working position and makes the first pressing block 22 press against the lens.

[0049] Similarly, the second locking member 33 includes a second head 331 and a second rod portion 332. The second rod portion 332 extends vertically, and the second pressing block 32 is sleeved on the outer periphery of the second rod portion 332. The second rod portion 332 can pass through the second pressing block 32 and be screwed to the second carrier block 31, and the second head 331 abuts against the second pressing block 32. That is, in this embodiment, the side of the second rod portion 332 away from the second head 331 is formed as a second threaded segment 3321. The second locking member 33 can be screwed to the second carrier block 31 through the second threaded segment 3321. When the second rod portion 332 is screwed to the second carrier block 31, the second pressing block 32 is sleeved on the outer periphery of the portion of the second rod portion 332 located between the second head 331 and the second threaded segment 3321. The second head 331 abuts against the second pressing block 32. At this time, the second locking member 33 locks the second pressing block 32 to the third working position and makes the second pressing block 32 press against the lens.

[0050] Therefore, in this embodiment, the operator can lock the first pressure block 22 to the first working position and the second pressure block 32 to the third working position by tightening the first locking member 23 and the second locking member 33, thereby clamping the lens on both sides along its radial direction.

[0051] When it is necessary to place or remove the lens, the operator only needs to loosen the first locking member 23 and the second locking member 33, so that the first pressing block 22 can rotate from the first working position to the second working position around the axis of the first rod 232, and the second pressing block 32 can rotate from the third working position to the fourth working position around the axis of the second rod 332. After placing the lens, the operator only needs to rotate the first pressing block 22 from the second working position to the first working position around the axis of the first rod 232, and the second pressing block 32 from the fourth working position to the third working position around the axis of the second rod 332, and then retighten the first locking member 23 and the second locking member 33, so that the first clamping module 2 and the second clamping module 3 can clamp the lens on both sides along its radial direction.

[0052] It is worth noting that after the first locking member 23 locks the first pressing block 22, the first pressing block 22 and the first carrier block 21 have a gap in the vertical direction. For example, in this embodiment, after the first locking member 23 locks the first pressing block 22, the first pressing block 22 and the first carrier block 21 have a gap of 0.05mm in the vertical direction, thereby ensuring that the lens is pressed tightly while preventing damage to the lens.

[0053] Accordingly, after the second locking member 33 locks the second pressing block 32, the second pressing block 32 and the second carrier block 31 have a gap in the vertical direction. For example, in this embodiment, after the second locking member 33 locks the second pressing block 32, the second pressing block 32 and the second carrier block 31 have a gap of 0.05mm in the vertical direction, thereby ensuring that the lens is not damaged while pressing the lens.

[0054] In addition, in this embodiment, the first head 231 and the second head 331 are respectively provided with a first knob 233 and a second knob 333. The first knob 233 is coaxial with the first rod 232, and the second knob 333 is coaxial with the second rod 332. The first knob 233 can facilitate the operator to turn the first locking member 23, and the second knob 333 can facilitate the operator to turn the second locking member 33.

[0055] Furthermore, based on the above, in this embodiment, the first pressing block 22 can rotate around the axis of the first rod 232 between the first working position and the second working position, and the second pressing block 32 can rotate around the axis of the second rod 332 between the third working position and the fourth working position.

[0056] It is worth noting that the first carrier block 21 is provided with a first limiting block 212 and a second limiting block 213. The first limiting block 212 can stop the first pressing block 22 in the first working position, and the second limiting block 213 can stop the first pressing block 22 in the second working position. Specifically, when the first pressing block 22 rotates from the first working position to the second working position, the first pressing block 22 abuts against the second limiting block 213; when the first pressing block 22 rotates from the second working position to the first working position, the first pressing block 22 abuts against the first limiting block 212. The first limiting block 212 and the second limiting block 213 can limit the rotation range of the first pressing block 22, thereby providing an indication for the operator's operation.

[0057] Correspondingly, the second block 31 is provided with a third limiting block 312 and a fourth limiting block 313. The third limiting block 312 can stop the second pressing block 32 in the third working position, and the fourth limiting block 313 can stop the second pressing block 32 in the fourth working position. Specifically, when the second pressing block 32 rotates from the third working position to the fourth working position, the second pressing block 32 abuts against the fourth limiting block 313; when the second pressing block 32 rotates from the fourth working position to the third working position, the second pressing block 32 abuts against the third limiting block 312. The third limiting block 312 and the fourth limiting block 313 can limit the rotation range of the second pressing block 32, thereby providing an indication for the operator's operation.

[0058] When the first clamping module 2 clamps the lens along one side of its radial direction and the second clamping module 3 clamps the lens along the other side of its radial direction, the first tension gauge and the second tension gauge need to pull the first clamping module 2 and the second clamping module 3 to move in opposite directions, so as to perform a tensile test on the lens.

[0059] Therefore, in this embodiment, the platform 1 is provided with a first guide groove 11 and a second guide groove 12. Both the first guide groove 11 and the second guide groove 12 extend along the arrangement direction of the first clamping module 2 and the second clamping module 3. The platform 1 is sleeved on the outer periphery of the first carrier block 21 through the first guide groove 11 and on the outer periphery of the second carrier block 31 through the second guide groove 12. The first guide groove 11 can provide guidance for the movement of the first clamping module 2, and the second guide groove 12 can provide guidance for the movement of the second clamping module 3, thereby ensuring that the first tension gauge and the second tension gauge stretch the lens in the same direction, so as to achieve accurate stretching of the lens and thus ensure the accuracy of the test results.

[0060] Understandably, after the tensile test, the first clamping module 2 and the second clamping module 3 are reset, that is, the side of the first carrier block 21 facing the second carrier block 31 is reset to abut against the platform 1, and the side of the second carrier block 31 facing the first carrier block 21 is reset to abut against the platform 1.

[0061] Based on the above, in this embodiment, the first pull head 211 and the second pull head 311 are respectively provided with a first hook 2111 and a second hook 3111. The first hook 2111 and the second hook 3111 respectively hook the first tension gauge and the second tension gauge. The first tension gauge can pull the first clamping module 2 through the first hook 2111, and the second tension gauge can pull the second clamping module 3 through the second hook 3111, thereby causing the first clamping module 2 and the second clamping module 3 to move in opposite directions.

[0062] It is understood that since the specific structure and working principle of the first and second force gauges are existing technologies, this embodiment will not elaborate on them.

[0063] In addition, in this embodiment, both the first hook 2111 and the second hook 3111 are U-shaped, thereby ensuring that the first tension gauge can be securely hooked to the first pull head 211 and the second tension gauge can be securely hooked to the second pull head 311. That is, this embodiment can prevent the first hook 2111 from detaching from the first tension gauge and prevent the second hook 3111 from detaching from the second tension gauge, thereby ensuring that the first tension gauge and the second tension gauge can stretch the lens smoothly and accurately.

[0064] Furthermore, it should be noted that in this embodiment, the contact lens testing device also includes a base 4, and the stage 1, the first carrier block 21 and the second carrier block 31 are all mounted on the base 4. The base 4 can provide a horizontal mounting platform for the stage 1, the first carrier block 21 and the second carrier block 31, thereby ensuring that the first carrier block 21 and the second carrier block 31 are flush with the stage 1.

[0065] Furthermore, the base 4 can ensure that the first pull head 211 and the second pull head 311 are at the same height, thereby ensuring that the first tension gauge and the second tension gauge apply tension at the same height, and further ensuring the accuracy of the test results.

[0066] Furthermore, both the side of the first pressing block 22 facing the first carrier block 21 and the side of the first carrier block 21 facing the first pressing block 22 are frosted surfaces, thereby increasing the friction between the first pressing block 22 and the first carrier block 21 and the lens, so as to prevent the lens from coming loose from between the first pressing block 22 and the first carrier block 21 during the test.

[0067] Accordingly, the side of the second pressing block 32 facing the second carrier block 31 and the side of the second carrier block 31 facing the second pressing block 32 are both frosted surfaces, thereby increasing the friction between the second pressing block 32 and the second carrier block 31 and the lens, so as to prevent the lens from coming loose between the second pressing block 32 and the second carrier block 31 during the test.

[0068] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
