Description

Technical Field

[0001] The utility model relates to the field of testing equipment, in particular to a scratch resistance tester for a display glass cover plate. Background Technique

[0002] With the development of society, the display manufacturing industry is also developing rapidly. The glass cover plate is becoming more and more particular about wear resistance, scratch resistance, drop resistance and other data to ensure a longer service life of the glass cover plate. To ensure the normal factory sale of the display, the display glass cover plate must undergo a scratch resistance test, and only after meeting the standard can the next inspection be carried out, and the final quality is guaranteed before leaving the factory for sale.

[0003] The existing scratch resistance tester for display glass cover plates is mainly for flat glass cover plates. The flat glass cover plate is placed on a sliding plate, and the glass cover plate is pressed down with bolts to ensure that the glass cover plate is fixed on the sliding plate and not easy to loosen. Then, the scratching fingertip is adjusted to the position where it touches the glass cover plate. According to the experimental requirements, weights are added above the scratching fingertip. Finally, the machine is started, and the sliding plate drives the glass cover plate to slide under the scratching fingertip for the scratch resistance test.

[0004] However, it is not easy for the existing scratching fingertip to detect the experimental data of the arc glass cover plate at one time, which leads to the need for some arc glass cover plates to be detected at different angles multiple times, resulting in a long experimental time and too high experimental cost. Moreover, the single fixing method of the existing detection machine cannot meet the fixing requirements of the arc glass, which will cause the arc glass cover plate to move during the detection process, resulting in the forced interruption of the detection experiment. Content of the Utility Model

[0005] Based on this, the purpose of the utility model is to provide a scratch resistance tester for a display glass cover plate to solve the technical problem that it is not easy for the existing scratching fingertip to detect the scratch resistance data of the arc glass cover plate.

[0006] To achieve the above purpose, the utility model provides the following technical scheme: A scratch resistance tester for a display glass cover plate, including a base and a support frame. A support frame is installed on one side of the base. It is characterized in that: A sliding plate is movably installed on one side of the base, and a fixing component is installed on one side of the sliding plate. A connecting rod is installed through the upper part of the support frame, and a weight is sleeved on the outer wall of the connecting rod. One end of the connecting rod is installed with a connecting block, and a scratching fingertip is movably installed at the bottom of the connecting block. A rotating group frame is installed on one side of the support frame, and an arc glass cover plate is installed on the sliding plate.

[0007] By adopting the above technical solution, the problem that the scratch resistance data of the arc-shaped glass cover plate is not easily detected by the existing scratch fingertip is solved. When it is necessary to detect the arc-shaped glass cover plate, the arc-shaped glass cover plate is fixed to the sliding plate, the rotating block is rotated, the angle of the movable block is adjusted so that the scratch fingertip connected to the movable block contacts the arc-shaped glass cover plate, and then the rotating block is rotated in the reverse direction to make the rotating block squeeze the movable block to fit with the fixed block. The rubber block between the movable block, the fixed block and the rotating block plays a role in increasing the friction between them, so that the movable block is fixed at the adjusted position. At this time, the device is started again, and the scratch fingertip can slide at multiple places on the arc-shaped glass cover plate, and finally the comprehensive scratch resistance data of the arc-shaped glass cover plate can be obtained.

[0008] The utility model is further arranged such that a first chute is opened on one side of the base, a sliding rod is installed inside the first chute, and a motor is arranged inside the first chute.

[0009] By adopting the above technical solution, the motor can drive the sliding plate to move inside the first chute, and the sliding rod can also assist the movement of the sliding plate, so that the sliding plate will not deviate due to too fast movement speed.

[0010] The utility model is further arranged such that a support plate is installed on one side of the sliding plate, a rotating handle is installed above the support plate, and a second chute is opened on one side of the sliding plate.

[0011] By adopting the above technical solution, the second chute can limit the movement trajectories of the support plate and the fixing component, and the rotating handle can fix the support plate at the required position to ensure that the fixed support plate and the fixing component will not move.

[0012] The utility model is further arranged such that the fixing component includes a slider movably installed on one side of the sliding plate, the cross section of the slider is L-shaped, a rotating handle is installed through the top of the slider, and a movable plate is movably installed at one end of the slider.

[0013] By adopting the above technical solution, when the slider slides close to the arc-shaped glass cover plate, the movable plate will first contact one side of the arc-shaped glass cover plate. As the slider gets closer and closer to the arc-shaped glass cover plate, the movable plate will fit the radian until the slider can no longer get closer. At this time, the rotating handle is rotated to fix the slider here. The fixing component fixes the arc-shaped glass cover plate from two directions, above and side, to prevent the arc-shaped glass cover plate from moving during the experiment.

[0014] The utility model is further arranged such that the rotating group frame includes a fixed block installed at the bottom of the support frame, a hole is opened at the top of the fixed block, and the cross section of the fixed block is T-shaped.

[0015] By adopting the above technical solution, the hole can meet the installation of the connecting rod, and the T-shaped fixed block can be installed with the movable block by bearing. When the rotating block rotates, the movable block and the fixed block can be more closely fitted and not easily loosened.

[0016] The utility model is further arranged such that movable blocks are movably installed at both ends of the fixed block, a lead screw is movably installed inside the movable block, and a rotating block is sleeved on the outer wall of the lead screw.

[0017] By adopting the above technical solution, the inner wall of the rotating block is also provided with threads. When the rotating block is rotated clockwise, the rotating block will squeeze the movable block to fit with the fixed block until the movable block is fixed and cannot move. When the rotating block is rotated in the reverse direction, the movable block can rotate freely.

[0018] The utility model is further arranged such that a rubber block is arranged on one side of the rotating block, and the rubber block is in contact with one side of the movable block. A rubber block is arranged on one side of the fixed block, and the rubber block is in contact with the other side of the movable block.

[0019] By adopting the above technical solution, the rubber block plays a buffering role and increases the friction between them among the fixed block, the movable block and the rotating block, so that the movable block is not easy to move.

[0020] In summary, the utility model mainly has the following beneficial effects:

[0021] 1. By providing a connecting rod, a connecting block, a scratching fingertip, a fixed block, a hole, a movable block, a lead screw, a rotating block and a rubber block, the utility model solves the problem that the existing scratching fingertip is not easy to detect the scratch resistance data of the arc glass cover plate. When it is necessary to detect the arc glass cover plate, the arc glass cover plate is fixed on the sliding plate, the rotating block is rotated to adjust the angle of the movable block, so that the scratching fingertip connected to the movable block contacts the arc glass cover plate, and then the rotating block is rotated in the reverse direction to squeeze the movable block to fit with the fixed block. The rubber block among the movable block, the fixed block and the rotating block plays a role in increasing the friction between them, so that the movable block is fixed at the adjusted position. At this time, the device is started, and the scratching fingertip can slide at multiple places on the arc glass cover plate, and finally the comprehensive scratch resistance data of the arc glass cover plate can be obtained;

[0022] 2. By providing a sliding plate, a support plate, a second chute, a fixing assembly, a slider, a rotating handle and a movable plate, the utility model solves the problem that the arc glass cover plate cannot be fixed on the sliding plate. When the arc glass cover plate is placed on the sliding plate, the support plate is pushed to fix both ends of the arc glass cover plate. At this time, the rotating handle installed on the support plate is rotated to fix the support plate at this position. Then the sliders on both sides are pushed. When the movable plate is in close contact with the glass cover plate, the rotating handle on the slider is rotated to fix the slider at this position. Thus, all four sides of the arc cover plate are fixed, and the movable plate limits the upper part of the arc glass cover plate, restricting all moving directions of the arc glass cover plate, so that the arc glass cover plate is firmly fixed on the sliding plate, facilitating the subsequent scratch resistance experiment.

[0033] Next, the embodiments of the present utility model will be described according to the overall structure of the present utility model.

[0034] A scratch resistance tester for a display glass cover plate, as Figure 1 - Figure 7 shown, includes a base 1 and a support frame 2, and a support frame 2 is installed on one side of the base 1.

[0035] Specifically, a sliding plate 3 is movably installed on one side of the base 1, and a fixing component 4 is installed on one side of the sliding plate 3. A connecting rod 5 is installed through the upper part of the support frame 2, and a weight 6 is sleeved on the outer wall of the connecting rod 5. One end of the connecting rod 5 is installed with a connecting block 51, and a scraping fingertip 52 is movably installed at the bottom of the connecting block 51. A rotating group frame 7 is installed on one side of the support frame 2, and an arc-shaped glass cover plate 8 is installed on the sliding plate 3.

[0036] Please refer to Figure 1 and Figure 2 , a first sliding groove 101 is opened on one side of the base 1, and a sliding rod 102 is installed inside the first sliding groove 101. A motor is arranged inside the first sliding groove 101, and the motor can drive the sliding plate 3 to move inside the first sliding groove 101. The sliding rod 102 can also assist the movement of the sliding plate 3 to prevent the sliding plate 3 from shifting due to too fast movement speed.

[0037] Please refer to Figure 1 、 Figure 2 and Figure 6 , a support plate 31 is installed on one side of the sliding plate 3, and a turning handle 42 is installed above the support plate 31. A second sliding groove 32 is opened on one side of the sliding plate 3. The second sliding groove 32 can limit the movement track of the support plate 31 and the fixing component 4, and the turning handle 42 can fix the support plate 31 at the required position to ensure that the fixed support plate 31 and the fixing component 4 will not move.

[0038] Please refer to Figure 5 - Figure 7 , the fixing component 4 includes a slider 41 movably installed on one side of the sliding plate 3, and the cross-section of the slider 41 is L-shaped. A turning handle 42 is installed through the top of the slider 41, and a movable plate 43 is movably installed at one end of the slider 41. When the slider 41 slides close to the arc-shaped glass cover plate 8, the movable plate 43 will first contact one side of the arc-shaped glass cover plate 8. As the slider 41 gets closer and closer to the arc-shaped glass cover plate 8, the movable plate 43 will fit the arc until the slider 41 can no longer move closer. At this time, the turning handle 42 is rotated to fix the slider 41 in place. The fixing component 4 fixes the arc-shaped glass cover plate 8 from two directions, above and side, to prevent the arc-shaped glass cover plate 8 from moving during the experiment.

[0039] Please refer to Figure 3 and Figure 4 , the rotating group frame 7 includes a fixing block 71 installed at the bottom of the support frame 2, and a hole 72 is opened at the top of the fixing block 71. The cross-section of the fixing block 71 is T-shaped. The hole 72 can meet the installation of the connecting rod 5, and the T-shaped fixing block 71 can be installed with the movable block 73 through a bearing. When the rotating block 75 rotates, the movable block 73 and the fixing block 71 can be more closely fitted and not easily loosened.

[0040] Please refer to Figure 3 and Figure 4, movable blocks 73 are movably installed at both ends of the fixed block 71, and a lead screw 74 is movably installed inside the movable block 73. A rotating block 75 is sleeved on the outer wall of the lead screw 74, and threads are also provided on the inner wall of the rotating block 75. When the rotating block 75 is rotated clockwise, the rotating block 75 will squeeze the movable block 73 to fit with the fixed block 71 until the movable block 73 is fixed and cannot move. When the rotating block 75 is rotated in the opposite direction, the movable block 73 can rotate freely.

[0041] Please refer to Figure 3 , Figure 4 and Figure 8 , a rubber block 76 is provided on one side of the rotating block 75, and the rubber block 76 is in contact with one side of the movable block 73. A rubber block 76 is provided on one side of the fixed block 71, and the rubber block 76 is in contact with the other side of the movable block 73. The rubber block 76 plays a buffering role and increases the friction between them among the fixed block 71, the movable block 73 and the rotating block 75, making it difficult for the movable block 73 to move.

[0042] The working principle of the present utility model is as follows: when it is necessary to detect the scratch resistance data of the arc-shaped glass cover plate 8, the arc-shaped glass cover plate 8 is placed above the sliding plate 3, and the highest point of the arc is kept in a parallel position with the support frame 2. At this time, the support plate 31 is pushed to limit both ends of the arc-shaped glass cover plate 8 between the protrusions of the support plate 31 and the sliding plate 3, and the rotating handle 42 above the support plate 31 is rotated to fix the support plate 31 here.

[0043] Subsequently, the sliders 41 on both sides are pushed until the movable plate 43 at the end of the slider 41 rotates and fits with the arc-shaped glass cover plate 8. At this time, the rotating handle 42 is rotated to fix the slider 41 here. Thus, the four sides of the arc-shaped glass cover plate 8 are fixed, and the movable plate 43 pressing against the side of the arc-shaped glass cover plate 8 will exert a downward force, and the movable plate 43 will limit the arc-shaped glass cover plate 8 so that it will not move up and down.

[0044] After the arc-shaped glass cover plate 8 is fixed, a set of connecting rods 5 are inserted through the support frame 2 and the fixed block 71, another set of connecting rods 5 are installed through the movable block 73, a connecting block 51 is installed at the end of the connecting rod 5, and finally a scratching fingertip 52 is installed on the connecting block 51. The position of the scratching fingertip 52 on the fixed block 71 is adjusted until the scratching fingertip 52 contacts the arc-shaped glass cover plate 8.

[0045] Rotate a set of rotating blocks 75 of the rotating group frame 7 that are kept in the same horizontal position to make the movable block 73 rotatable until the scratching fingertip 52 installed on the movable block 73 contacts the arc-shaped glass cover plate 8. At this time, rotate the rotating block 75 in the reverse direction. The threads on the inner wall of the rotating block 75 are opposite to the threads of the lead screw 74 until the rotating block 75 is pressed against the movable block 73 and squeezes the movable block 73 to fit with the fixed block 71, so that the movable block 73 is fixed here and will not move, ensuring that the subsequent experimental process can proceed normally.

[0046] At this point, the arc-shaped glass cover plate 8 is firmly fixed on the sliding plate 3, and all three scraping fingertips 52 are in contact with the arc-shaped glass cover plate 8. At this time, weights 6 are added above the connecting rod 5, and then the device is started. The motor installed inside the first chute 101 drives the sliding plate 3 to slide within the first chute 101, and the sliding speed, number of times, and the weight of the weights 6 are set according to the monitoring requirements.

[0047] Although the embodiments of the present invention have been shown and described, the specific embodiments are only explanations of the present invention and not limitations thereof. The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can make modifications, substitutions, and variations that do not make creative contributions to the embodiments according to their needs, but as long as they are within the scope of the claims of the present invention, they are protected by the patent law.
