Description

Technical Field

[0001] The utility model belongs to the technical field of wear resistance testing, and particularly relates to a diaphragm wear resistance testing platform. Background Art

[0002] Liquid crystal displays have been widely used in life. A liquid crystal display includes a plurality of optical diaphragms such as a light guide plate, an upper diffusion sheet, and a lower diffusion sheet. During use, due to vibrations and other reasons, relative movement occurs between the optical diaphragms, resulting in friction. To ensure the quality of the liquid crystal display, each optical diaphragm needs to have a certain wear resistance. Therefore, during production, it is necessary to detect the wear resistance between the optical diaphragms.

[0003] The existing diaphragm wear resistance testing platforms generally can only test a single position of the diaphragm. When a complete test is required, the position of the diaphragm needs to be adjusted manually, which greatly limits the testing efficiency of the diaphragm and is inconvenient to use.

[0004] As can be seen from the above, the existing diaphragm wear resistance testing platforms cannot perform multi-position testing, have low testing efficiency, and are not suitable for popularization and use. Summary of the Utility Model

[0005] The purpose of the embodiments of the utility model is to provide a diaphragm wear resistance testing platform to solve the above technical problems. The diaphragm wear resistance testing platform includes:

[0006] A box body; and a testing component connected to the box body for performing wear resistance testing on the diaphragm;

[0007] The testing component includes:

[0008] A driving member connected to the box body through a motor bracket; and a rotating shaft fixedly connected to the output end of the driving member, and the end of the rotating shaft away from the driving member is rotatably connected to the inner side wall of the box body;

[0009] A first bevel gear fixedly connected to the rotating shaft; and a second bevel gear meshing with the first bevel gear;

[0010] A crank is fixedly connected to the second bevel gear, and the end of the crank away from the second bevel gear is connected to the box body through a fixing piece;

[0011] A connecting rod is provided on the crank, and the end of the connecting rod away from the crank is connected to a slider.

[0012] Further, a notch is opened at the top of the box body.

[0013] Further, the slider is connected to a test block through a fixing bolt, and the test block is attached to the top of the notch.

[0014] Further, the diaphragm wear resistance test bench further includes:

[0015] An auxiliary component, connected to the test component, for assisting in the diaphragm wear resistance test.

[0016] Further, the auxiliary component includes:

[0017] A third bevel gear, fixedly connected to the middle of the rotating shaft; and a fourth bevel gear meshing with the third bevel gear through a thread;

[0018] The fourth bevel gear is coaxially connected with a test head.

[0019] The diaphragm wear resistance test bench provided by the present utility model can test the diaphragm by setting the test component. At the same time, the test is convenient and the use is simple. By setting the auxiliary component, the auxiliary test of the diaphragm can be carried out, greatly broadening the test range of the diaphragm.

[0027] A box body 1; and a test assembly 2 connected to the box body 1 for performing a wear resistance test on the diaphragm;

[0028] The test assembly 2 comprises:

[0029] A driving member connected to the box body 1 through a motor bracket 201; and a rotating shaft 203 fixedly connected to the output end of the driving member, one end of the rotating shaft 203 away from the driving member is rotatably connected to the inner side wall of the box body 1;

[0030] A first bevel gear 204 is fixedly connected to the rotating shaft 203; and a second bevel gear 205 meshing with the first bevel gear 204;

[0031] A crank 206 is fixedly connected to the second bevel gear 205, and one end of the crank 206 away from the second bevel gear 205 is connected to the box body 1 through a fixing piece 207;

[0032] A connecting rod 208 is provided on the crank 206, and one end of the connecting rod 208 away from the crank 206 is connected to a slider 209.

[0033] In the embodiment of the present utility model, the size and shape of the box body 1 are not limited. The size of the box body 1 should be determined according to the size of the test assembly 2 on one side thereof. The shape of the box body 1 is also not limited. It may be cabinet-shaped, box-shaped, or other required shapes.

[0034] In this embodiment, a motor bracket 201 is fixedly connected to the side wall of the box body 1, and a driving member is installed on the motor bracket 201. The driving member is a servo motor 202, and may also be a stepping motor. In this embodiment, it is a servo motor 202. The output end of the servo motor 202 is fixedly connected to a rotating shaft 203. The right end of the rotating shaft 203 (as shown in the attached drawings of the specification Figure 1 is rotatably connected to the inner side wall of the box body 1. A first bevel gear 204 is fixedly connected to the rotating shaft 203. A second bevel gear 205 is meshed above the first bevel gear 204. A crank 206 is coaxially connected above the second bevel gear 205. The top of the crank 206 is rotatably connected to a fixing piece 207 on the side wall of the box body 1. A connecting rod 208 is sleeved on the crank 206, and the other end of the connecting rod 208 is sleeved with a slider 209.

[0035] In actual use, when the servo motor 202 is started, the rotating shaft 203 can be rotated, driving the first bevel gear 204 to rotate, thus causing the second bevel gear 205 to rotate and driving the crank 206 to rotate. Then, through the connecting rod 208, the slider 209 is driven to move.

[0036] In this embodiment, the number of the first bevel gear 204, the second bevel gear 205, the crank 206, the connecting rod 208 and the fixing piece 207 is two groups. The two groups of the first bevel gear 204, the second bevel gear 205, the crank 206, the connecting rod 208 and the fixing piece 207 are symmetrically distributed on both sides of the box body 1. When the two fixing pieces 207 approach each other, multi-position wear resistance tests can be performed on the diaphragm, thereby further improving the test efficiency of the diaphragm.

[0037] In an embodiment of the present utility model, please refer to Figure 1 , a notch 2010 is formed at the top of the box body 1.

[0038] In this embodiment, a notch 2010 is formed at the top of the box body 1. The notch 2010 is mainly used to place the diaphragm and can also prevent the diaphragm from moving significantly during the test.

[0039] In an embodiment of the present utility model, please refer to Figure 2 , the slider 209 is connected with a test block 2012 through a fixing bolt 2011, and the test block 2012 is attached to the top of the notch 2010.

[0040] In this embodiment, by using the fixing bolt 2011, the slider 209 and the test block 2012 can be combined. The advantage of this is that the distance between the slider 209 and the test block 2012 can be adjusted, so that the test block 2012 can fully contact the diaphragm to ensure the test efficiency. At the same time, the test block 2012 can also be removed from the slider 209 by using the fixing bolt 2011, so as to quickly replace the test block 2012.

[0041] In an embodiment of the present utility model, please refer to Figure 1 , the diaphragm wear resistance test bench further includes:

[0042] An auxiliary component 3, connected to the test component 2, for assisting in performing the diaphragm wear resistance test.

[0043] In this embodiment, through the setting of the auxiliary component 3, the diaphragm can be tested, further improving the test efficiency.

[0044] In an embodiment of the present utility model, please refer to Figure 3 , the auxiliary component 3 includes:

[0045] The third bevel gear 301 is fixedly connected to the middle part of the rotating shaft 203; and the fourth bevel gear 302 meshed with the third bevel gear 301 through threads;

[0046] A test head 303 is coaxially connected to the fourth bevel gear 302.

[0047] In this embodiment, the third bevel gear 301 is fixedly connected to the middle part of the rotating shaft 203. The fourth bevel gear 302 is meshed above the third bevel gear 301. A test head 303 is coaxially connected to one side above the fourth bevel gear 302. The test head 303 is in contact with the bottom of the diaphragm. When the rotating shaft 203 rotates, the third bevel gear 301 rotates simultaneously and drives the fourth bevel gear 302 to rotate through meshing, so that the test head 303 rotates to perform wear resistance test on the bottom of the diaphragm.

[0048] In actual use, the diaphragm is placed into the notch 2010, and the servo motor 202 is started, so that the rotating shaft 203 can rotate and drive the first bevel gear 204 to rotate, so that the second bevel gear 205 rotates and drives the crank 206 to rotate. Then, through the connecting rod 208, the slider 209 is driven to move to perform wear resistance test on the top surface of the diaphragm. When the rotating shaft 203 rotates, the third bevel gear 301 rotates simultaneously and drives the fourth bevel gear 302 to rotate through meshing, so that the test head 303 rotates to perform wear resistance test on the bottom of the diaphragm.

[0049] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
