Description

Technical Field

[0001] The utility model relates to the technical field of testing devices, in particular to a mobile phone glass cover scratch testing device. Background Art

[0002] The mobile phone glass cover scratch test device is an instrument specially used to evaluate the scratch resistance of the mobile phone glass surface. The device usually has an adjustable scratching needle, which simulates the scratching test of the mobile phone glass with substances of different hardness to detect the scratch resistance of the glass. During the test, the scratching needle is scratched on the glass surface with a certain pressure and speed, and the scratch resistance is evaluated by observing the length and width of the scratch and the degree of damage to the glass. Some advanced equipment may also contain precision pressure sensors and high-resolution imaging systems to record and analyze data more accurately.

[0003] According to the search, Chinese patent document, announcement number: CN213239764U, discloses that the utility model discloses a mobile phone glass cover scratch testing device, including a bracket, a base is arranged on one side of the bottom end of the bracket, a glass cover is arranged on the upper surface of the base, a fixed clamping plate is arranged on the side of the glass cover close to the bracket, a through groove is arranged inside the end of the base away from the bracket, a movable clamping plate is arranged through the through groove, an adjustment plate is arranged on the side of the lower end of the base close to the fixed clamping plate, a push plate is arranged on the side of the lower end of the base close to the movable clamping plate, and a roller is arranged at the bottom of the movable clamping plate. The mobile phone glass cover scratch testing device can effectively fix the glass cover by arranging the fixed clamping plate and the movable clamping plate, and can be applicable to glass cover plates of various sizes. By arranging a slider, multi-directional scratch detection of the glass cover can be achieved. By arranging an electric telescopic rod, the scratch nail can increase the scratch force, so that the scratch resistance detection result of the glass cover is more convincing.

[0004] In actual application, since the mobile phone glass cover scratch test device cannot perform scratch tests of multiple hardnesses on the mobile phone cover at the same time, the tester needs to repeatedly change scratch tools of different hardnesses to perform multiple tests, which increases the complexity and time cost of the operation. In addition, multiple tests may cause additional damage to the mobile phone cover, affecting the accuracy of the test results.

[0013] Compared with the prior art, this mobile phone glass cover scratch testing device has the following beneficial effects:

[0014] 1. In actual application of the utility model, the mobile phone is placed with the back plate facing upwards at the center of the top surface of the public plate, and the clamping motor is driven to drive the two-way adjustment shaft through the clamping motor. One end of the outer wall of the two-way adjustment shaft penetrates and rotates with the bottom end of the inner part of the positioning plate through a thread, and a group of sliders are fixedly connected on both sides of the top surface of the positioning plate, and the slider is placed at one end inside the guide groove.

The slider 104 is placed at one end inside the guide groove 102.

Since one end of the outer wall of the sliding shaft 203 penetrates and rotates with the bottom end of the lifting frame 202 through the thread, and one side of the bottom surface of the lifting frame 202 is in contact with one end of the top surface of the slide 2, and the sliding track is restricted by the slide 2, the sliding shaft 203 passes through the outer wall The thread drives the lifting frame 202, and simultaneously drives the mounting frame 204 and the Mohs scale knife 205 to slide along the surface of the mobile phone cover. The bottom of the Mohs scale knife 205 is equipped with a cutter arranged according to hardness, and scratch tests of multiple hardnesses can be performed at one time. Therefore, after the Mohs scale knife 205 is adjusted to a suitable position through the cooperation of the mounting frame 204 and the lifting frame 202, the bottom of the Mohs scale knife 205 is equipped with a cutter arranged according to hardness. In this way, when the sliding shaft 203 drives the Mohs scale knife 205 to slide across the mobile phone cover, scratch tests of multiple hardnesses can be performed at one time.

[0025] like Figure 1-2As shown, multiple sliders 104 are slidably connected at both ends of the guide groove 102, and the slider 104 is located on one side of the top surface of the positioning plate 101, the top outer wall of the slider 104 is fixedly connected to one side of the top surface of the positioning plate 101, and the positioning plate 101 is slidably connected to the top end of the guide groove 102 through the sliders 104 fixedly connected at the bottom two sides, and the positioning plate 101 is slidably connected to the top end of the guide groove 102, the inner center of the male plate 1 is rotatably connected with the two-way adjustment shaft 105, and the two-way adjustment shaft 105 is located at the bottom end of the positioning plate 101, one end of the outer wall of the two-way adjustment shaft 105 penetrates one end of the inner wall of the male plate 1 and is fixedly connected to the output end of the clamping motor 103, one end of the outer wall of the two-way adjustment shaft 105 penetrates and is connected to the center of the bottom end of the outer wall of the positioning plate 101, and one end of the outer wall of the two-way adjustment shaft 105 is rotatably connected to the bottom end of the positioning plate 101 through a thread, and the positioning plate 101 is located at both ends of the outer wall of the two-way adjustment shaft 105.

[0026] After the mobile phone back plate faces upwards and is placed at the center of the top surface of the public plate 1, the clamping motor 103 is driven, and the two-way adjustment shaft 105 is driven by the clamping motor 103. Since one end of the outer wall of the two-way adjustment shaft 105 penetrates and is rotatably connected to the inner bottom end of the positioning plate 101 through a thread, and a group of sliders 104 are fixedly connected on both sides of the top surface of the positioning plate 101, the slider 104 is placed at one end inside the guide groove 102, and the movement trajectory of the positioning plate 101 is limited by the guide groove 102 and the slider 104, so that the positioning plate 101 can only slide along the inner wall of the guide groove 102. After the two-way adjustment shaft 105 is rotated, the positioning plate 101 is effectively driven through the outer wall thread, so that a group of corresponding positioning plates 101 on both sides of the top surface of the public plate 1 slide along the inner wall of the guide groove 102 toward the edge of the mobile phone at the same time, the mobile phone can be limited, so that the two-way adjustment shaft 105 and the positioning plate 101 can be effectively cooperated with each other, so that the device can fix the mobile phone at the center of the top surface of the public plate 1, which is convenient for the subsequent scratch test of the mobile phone cover.

[0027] like Figure 1-4 As shown, the top of the lifting frame 202 is slidably connected to the mounting frame 204, and the bottom end of one side of the mounting frame 204 is fixedly connected to a Morse scale knife 205, and both sides of the lifting frame 202 are fixedly connected to multiple slide rails 206, and the slide rails 206 are located on both sides of the mounting frame 204, and one side of the lifting frame 202 is rotatably connected to a lifting shaft 207, and the lifting shaft 207 is located on one side of the bottom of the mounting frame 204, the top of the outer wall of the lifting shaft 207 is connected through one side of the bottom surface of the mounting frame 204, and the top outer wall of the lifting shaft 207 is rotatably connected to one side of the mounting frame 204 through a thread, and the top outer wall of the lifting shaft 207 is rotatably connected to one side of the mounting frame 204 through a thread, and the top of one side of the lifting frame 202 is fixedly connected to a lifting motor 208, and the output end of the lifting motor 208 and the top outer wall of the lifting shaft 207 are fixedly connected with meshing teeth 209, and the top outer wall of the lifting shaft 207 is rotationally intercepted with the output end of the lifting motor 208 through the meshing teeth 209.

[0028] The lifting motor 208 is driven, so that the output end of the lifting motor 208 drives the lifting shaft 207 to rotate on one side of the lifting frame 202 through the meshing teeth 209. Since the lifting shaft 207 penetrates and rotates with the top side of the mounting frame 204 through the outer wall thread, and is connected with a set of slide rails 206 on both sides of the mounting frame 204 for sliding connection, when the lifting shaft 207 rotates, the lifting shaft 207 drives the mounting frame 204 and the Mohs scale knife 205 to vertically descend along the outer wall of the slide rail 206 through the outer wall thread, until it contacts the mobile phone cover and cannot continue to descend, and then drives the sliding motor 201 to drive the sliding shaft 203 to rotate through the output end of the sliding motor 201. Since one end of the outer wall of the sliding shaft 203 penetrates and rotates with the bottom end of the lifting frame 202 through the thread, and a group of slide rails 206 are slidably connected on both sides of the mounting frame 204, when the lifting shaft 207 rotates, the lifting shaft 207 drives the mounting frame 204 and the Mohs scale knife 205 to vertically descend along the outer wall of the slide rail 206 through the outer wall thread, until it contacts the mobile phone cover and cannot continue to descend, and then drives the sliding motor 201 to drive the sliding shaft 203 to rotate through the output end of the sliding motor 201. The lifting frame 202 is rotatably connected, and one side of the bottom surface of the lifting frame 202 is in contact with one end of the top surface of the slide 2. After the sliding trajectory is limited by the slide 2, the sliding shaft 203 drives the lifting frame 202 through the outer wall thread, and simultaneously drives the mounting frame 204 and the Mohs scale knife 205 to slide along the surface of the mobile phone cover. The bottom of the Mohs scale knife 205 is equipped with a cutter arranged according to hardness, and scratch tests of multiple hardnesses can be performed at one time. Therefore, after the Mohs scale knife 205 can be adjusted to a suitable position through the cooperation of the mounting frame 204 and the lifting frame 202, the bottom of the Mohs scale knife 205 is equipped with a cutter arranged according to hardness. In this way, when the sliding shaft 203 drives the Mohs scale knife 205 to slide across the mobile phone cover, scratch tests of multiple hardnesses can be performed at one time.

[0029] Working principle: In actual application, the mobile phone back plate is placed upward on the center of the top surface of the male plate 1, and the clamping motor 103 is driven to drive the two-way adjustment shaft 105 through the clamping motor 103. One end of the outer wall of the two-way adjustment shaft 105 penetrates and rotates with the bottom end of the inner part of the positioning plate 101 through a thread, and a group of sliders 104 are fixedly connected on both sides of the top surface of the positioning plate 101. The slider 104 is placed at one end inside the guide groove 102, and the movement trajectory of the positioning plate 101 is limited by the guide groove 102 and the slider 104, so that the positioning plate 101 can only slide along the inner wall of the guide groove 102. After the two-way adjustment shaft 105 rotates, the positioning plate 101 is effectively driven through the outer wall thread, so that a group of corresponding positioning plates 101 on both sides of the top surface of the male plate 1 slide along the inner wall of the guide groove 102 toward the edge of the mobile phone at the same time, so that the mobile phone can be limited, and the lifting motor 208 is driven, so that the output end of the lifting motor 208 drives the lifting shaft 207 to rotate on one side of the lifting frame 202 through the meshing teeth 209. The lifting shaft 207 penetrates and is rotatably connected to one side of the top of the mounting frame 204 through the outer wall thread, and a set of slide rails 206 are slidably connected to both sides of the mounting frame 204. When the lifting shaft 207 rotates, the lifting shaft 207 drives the mounting frame 204 and the Mohs scale knife 205 to vertically descend along the outer wall of the slide rail 206 through the outer wall thread until they are in contact with the mobile phone cover and cannot continue to descend, and then drives the sliding motor 201 to drive the sliding shaft 203 to rotate through the output end of the sliding motor 201. Since one end of the outer wall of the sliding shaft 203 passes through the bottom end of the lifting frame 202 through a thread and is rotatably connected, and one side of the bottom surface of the lifting frame 202 is in contact with one end of the top surface of the slide 2, and after the sliding trajectory is restricted by the slide 2, the sliding shaft 203 drives the lifting frame 202 through the outer wall thread, and simultaneously drives the mounting frame 204 and the Mohs scale knife 205 to slide along the surface of the mobile phone cover. The bottom of the Mohs scale knife 205 is equipped with a carving knife arranged according to hardness, so that scratch tests of multiple hardnesses can be performed at one time.
