Description

Technical Field

[0001] This utility model relates to the field of optical glass performance testing technology, and in particular to an auxiliary testing device for the wear resistance of optical glass. Background Technology

[0002] Coating the surface of optical glass not only makes the glass cover more aesthetically pleasing but also endows the surface with corresponding functions. In actual use environments, products will continuously come into contact with and rub against various objects, thus requiring a certain degree of wear resistance. Existing wear resistance auxiliary testing devices consist of a friction rod suspended above a testing table at the front end of a reciprocating cantilever, with a friction head positioned at the contact surface between the friction rod and the testing table. The friction between the friction head and the optical glass on the testing table simulates the usage environment of the optical glass. In other words, the wear resistance of the optical glass is determined by measuring the number of friction cycles on its surface. However, existing wear resistance auxiliary testing devices simply fix the friction rod to the front end of the cantilever, which results in the inability to adjust the friction force between the friction head and the optical glass surface.

[0003] How to solve the above-mentioned technical problems has become an urgent technical challenge for the industry. Utility Model Content

[0051] When the drive unit 101 moves, it drives the friction rod 104 to reciprocate on the testing table 106.

[0052] Example 1

[0053] In one exemplary embodiment, the optical glass wear resistance auxiliary testing device of this application is used to test the wear resistance of the coating on the surface of optical glass, such as the wear resistance of the anti-fingerprint film layer.

[0054] In one exemplary embodiment, the auxiliary testing device for the wear resistance of optical glass according to this application includes: a testing stage 106, such as... Figure 1 As shown.

[0055] In one exemplary embodiment, the testing stage 106 is used to place the optical glass 108 to be tested, that is, when testing the wear resistance of the optical glass 108 to be tested, the optical glass 108 to be tested is placed on the testing stage 106.

[0056] In one exemplary embodiment, the testing table 106 is further provided with a clamping plate 107, such as... Figure 1 As shown.

[0057] In one exemplary embodiment, the clamp 107 is used to fix the optical glass 108 to be tested onto the upper surface of the testing stage 106, such as... Figure 1 As shown.

[0058] In one exemplary embodiment, the clamp 107 includes a plurality of clamps.

[0059] In one exemplary embodiment, the testing stage 106 is provided with a plurality of positioning holes 110, such as Figure 1 As shown.

[0060] In one exemplary embodiment, the clamp 107 is fixed to the upper surface of the testing stage 106 via the positioning hole 110.

[0061] In one exemplary embodiment, the optical glass wear resistance auxiliary testing device of this application further includes: a driving unit 101, such as... Figure 1 As shown.

[0062] In one exemplary embodiment, the drive unit 101 may be mounted on a rack as needed, i.e., the rack is used to support the drive unit 101, and the drive unit 101 is not suspended in the air.

[0063] In one exemplary embodiment, a cantilever 102 is connected to the front end of the drive unit 101. When the drive unit 101 moves, it drives the cantilever 102 to perform a telescopic movement, such as... Figure 1 As shown, the cantilever 102 extends and retracts in the direction indicated by the arrow on the optical glass 108 to be tested.

[0064] In one exemplary embodiment, a friction rod 104 is provided through the end of the cantilever 102 away from the drive unit 101, and the friction rod 104 can pass through the cantilever 102 as needed.

[0065] In one exemplary embodiment, the friction rod 104 is located on the testing table 106, for example, the friction rod 104 is vertically disposed above the testing table 106, such as... Figure 1 As shown.

[0066] In one exemplary implementation, such as Figure 1 and 2 As shown, the friction rod 104 is equipped with a friction head 1043 at the contact end with the test table 106. It can be understood that the wear resistance performance of the optical glass is detected by relying on the friction between the friction head 1043 and the surface of the optical glass.

[0067] In one exemplary embodiment, the friction rod 104 is provided with a weight-bearing portion 105, such as... Figure 1 and Figure 4 As shown.

[0068] In one exemplary embodiment, a weight 109 is provided on the weight carrier 105, that is, the friction force between the friction head 1043 and the optical glass is adjusted by adjusting the weight 109.

[0069] In one exemplary embodiment, the side of the weight-bearing part 105 facing the testing stage 106 is suspended on the cantilever 102.

[0070] In one exemplary embodiment, when the drive unit 101 moves, it drives the friction rod 104 to reciprocate on the detection stage 106.

[0071] In one exemplary embodiment, since the weight bearing part 105 bears the weight 109 and applies the weight directly to the friction head 1043 at the end of the friction rod 104, the weight 109 can be adjusted as needed to adjust the friction force.

[0072] In one exemplary implementation, such as Figure 1 As shown, a friction rod positioning part 103 is provided at the end of the cantilever 102 away from the drive unit 101.

[0074] In one exemplary embodiment, the friction rod 104 is disposed within the through hole.

[0075] In one exemplary embodiment, the friction rod 104 is matched with the through hole, which can be understood as meaning that when the friction rod 104 is disposed in the through hole, there will be no large gap that would cause the friction rod 104 to wobble in the through hole.

[0076] In one exemplary implementation, such as Figure 1 As shown, a weight bearing part 105 is provided on the friction rod positioning part 103.

[0077] In one exemplary implementation, such as Figure 1 As shown, the weight-bearing part 105 is mounted on the friction rod 104.

[0078] In one exemplary embodiment, a gap is provided between the side of the weight-bearing part 105 facing the detection stage 106 and the friction rod positioning part 103.

[0079] In one exemplary embodiment, the friction rod positioning part 103 is provided with a first limiting part 1031, which can be a protrusion, such as... Figure 1 As shown.

[0080] In one exemplary embodiment, the weight-bearing portion 105 is provided with a second limiting portion 1053, which may be a notch, such as... Figure 3 As shown.

[0081] In one exemplary embodiment, the first limiting portion 1031 matches the second limiting portion 1053, for example, the first limiting portion 1031 and the second limiting portion 1053 are attached together.

[0082] In one exemplary embodiment, the first limiting part 1031 matches the second limiting part 1053 to restrict the friction rod 104 from rotating within the through hole.

[0083] In one exemplary embodiment, the weight carrier 105 may be fixed to the friction rod 104 as needed, or the weight carrier 105 may be fixedly connected to the friction rod 104; because the first limiting part 1031 and the second limiting part 1053 cooperate with each other to restrict the rotation of the weight carrier 105, the rotation of the friction rod 104 is also restricted.

[0084] In one exemplary embodiment, a bearing is provided inside the friction rod positioning part 103.

[0085] In one exemplary embodiment, a bearing is fitted onto a friction rod 104, which is matched with the bearing.

[0086] In one exemplary embodiment, a bearing is provided to facilitate placing the friction rod 104 into the through hole of the friction rod positioning part 103.

[0087] In one exemplary embodiment, the friction rod 104 includes a first body 1041 and a second body 1042.

[0088] In one exemplary embodiment, one end of the first body 1041 is connected to the friction head 1043, and the other end of the first body 1041 is connected to the second body 1042, as shown below. Figure 2 and Figure 4 As shown.

[0089] In one exemplary embodiment, the diameter of the second body 1042 is not greater than the diameter of the first body 1041.

[0090] In one exemplary embodiment, the weight-bearing portion 105 is sleeved on the second body 1042, such as... Figure 4 As shown.

[0091] In one exemplary implementation, such as Figure 3 As shown, a first through hole 1051 is provided on the weight bearing part 105.

[0092] In one exemplary embodiment, the weight-bearing part 105 is sleeved on the friction rod 104 through the first through hole 1051.

[0093] In one exemplary embodiment, the diameter of the first through hole 1051 matches that of the friction rod 104. As needed, the diameter of the first through hole 1051 can be larger than the diameter of the second body 1042 but smaller than the diameter of the first body 1041.

[0094] In one exemplary embodiment, the weight-bearing part 105 is further provided with a second through hole 1052.

[0095] In one exemplary embodiment, a fixing screw is provided in the second through hole 1052, and the fixing screw fixes the friction rod 104 in the first through hole 1051 through the second through hole 1052.

[0096] In one exemplary embodiment, the second through hole 1052 is perpendicular to the first through hole 1051.

[0097] In one exemplary embodiment, there may be multiple second through holes 1052, and the multiple second through holes 1052 surround the side of the weight support portion 105.

[0098] In one exemplary embodiment, a control unit may be included as needed, which is used to control the driving speed and driving time of the drive unit 101.
