Abstract

This invention provides a collision level detection mechanism for a grinding table, comprising: a support base; a positioning mechanism installed on one side of the support base, the positioning mechanism being used to fix the support base to one side of the grinding table, on which a grinding disc is movably mounted, the positioning mechanism including a mounting block installed on one side of the support base, a guide rail installed at the end of the mounting block away from the support base, a clamping plate slidably mounted on the guide rail along the direction of the mounting block, and a driving component installed on the guide rail for driving the clamping plate to slide; and a lifting mechanism installed on the support base. When detecting the collision level of the grinding table, if the grinding disc descends and contacts the stress plate, the pressure generated by the collision is higher than the stress value of the stress plate, causing the stress plate to break, the broken stress plate fragments remain in the receiving groove of the mounting base, thus eliminating the need for workers to clean the surface of the grinding table, facilitating use.

Description

Technical Field

[0001] This invention relates to the field of grinding workbench testing equipment, specifically to a grinding workbench collision level testing mechanism. Background Technology

[0002] A grinding table is a work platform used for precision grinding and polishing, commonly found in fields such as machining, optical manufacturing, and laboratories. In the manufacturing process of liquid crystal glass substrates, a grinding table is used to ensure that the surface of the substrate meets the requirements for high precision and flatness.

[0003] When polishing the surface of an LCD glass substrate using a polishing table, the polishing disc on the table can collide with the substrate upon lowering and contacting it, easily causing scratches, cracks, or unevenness on the substrate surface, thus affecting product quality. Therefore, when polishing LCD glass substrates of the same model and batch, it is necessary to perform collision level testing on the polishing table to avoid collisions caused by the polishing disc lowering and resulting in scratches, cracks, or unevenness. Currently, collision level testing of polishing tables often involves placing a test board on the polishing table, controlling the polishing disc to lower and contact the test board for polishing, and then observing whether there are scratches, cracks, or unevenness on the test board surface to achieve the effect of collision level testing. Although this method can achieve the collision level testing of the polishing table, it still has the following drawbacks in actual use:

[0004] If the grinding disc descends and comes into contact with the test board, the pressure generated by the collision with the test board is higher than the stress value of the test board. As a result, when the test board breaks, the broken test board remains on the surface of the grinding table, which requires the staff to clean the test board waste from the surface of the grinding table, which is quite troublesome.

[0005] Therefore, this application proposes a collision level detection mechanism for a grinding worktable. Summary of the Invention

[0006] To address the shortcomings of existing technologies, this invention provides a collision level detection mechanism for a grinding workbench, which solves the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A collision level testing mechanism for a grinding worktable, comprising:

[0009] Support;

[0010] A positioning mechanism is installed on one side of the support base. The positioning mechanism is used to fix the support base to one side of the grinding table. A grinding disc is movably installed on the grinding table and above it. The positioning mechanism includes a mounting block installed on one side of the support base. A guide rail is installed on the end of the mounting block away from the support base. A clamping plate is slidably installed on the guide rail along the direction of the mounting block. A driving component for driving the clamping plate to slide is installed on the guide rail.

[0011] A lifting mechanism is installed on a support base. A rotation adjustment component is installed on the top of the lifting mechanism, and a mounting base is installed on the top of the rotation adjustment component. The lifting mechanism is used to raise or lower the height of the rotation adjustment component, and the rotation adjustment component is used to adjust the position of the mounting base so that the mounting base is located outside the grinding table or between the grinding table and the grinding disc.

[0012] The stress plate has a receiving groove on the top of the mounting base. Four vertical spring telescopic rods are fixed in a circular array on the bottom wall of the receiving groove. A support plate is fixedly installed on the top of the four spring telescopic rods and inside the receiving groove. The cross-section of the support plate is cross-shaped. A pressure sensor in contact with the support plate is fixedly installed on the bottom wall of the receiving groove. The stress plate is placed on the top of the support plate and inside the receiving groove.

[0013] A limiting assembly, which is mounted on a mounting base, is used to limit the stress plate placed on top of the tray.

[0014] Furthermore: the driving assembly includes a threaded rod that is horizontally rotatably mounted on a guide rail, the threaded rod being threadedly connected to a clamping plate, and an electric motor for driving the threaded rod to rotate is fixedly mounted on the guide rail.

A horizontal telescopic rod 2 is symmetrically fixed on the side of the connecting plate 1 away from the connecting block. The ends of the two telescopic rods 2 are fixedly connected to the connecting plate 2. A drive rod that is connected to the connecting plate 2 is fixedly mounted on the connecting plate 1. The mounting base is fixedly connected to the connecting plate 2.

[0018] Furthermore: the limiting assembly includes a limiting seat, a limiting plate, and a resetting component. The limiting seat is fixedly installed on the top of the mounting base and on both sides of the receiving groove. The limiting plate is hinged to the limiting seat. The resetting component connected to the limiting plate is installed on the limiting seat. It is used to rotate and reset the limiting plate in the limiting seat so that the limiting plate is horizontal. When the limiting plate is horizontal, the end of the limiting plate extends above the receiving groove, and the bottom of the limiting plate is in contact with the top of the mounting base.

[0019] Furthermore: The limiting seat is equipped with a fixing component that acts on the limiting plate, which is used to fix or remove the fixing between the limiting plate and the limiting seat. The fixing component includes a fixing frame fixedly installed on one side of the limiting seat. A fixing frame is fixedly installed on the top of the fixing frame and on the side close to the limiting seat. A locking rod is horizontally movably inserted through the fixing frame. A locking hole is opened on the side of the limiting plate close to the fixing frame. A spring telescopic rod two, which is fixedly connected to the fixing frame, is fixedly installed on the side of the locking rod away from the limiting plate. When the limiting plate is vertical, the end of the locking rod can be inserted into the locking hole and locked with the limiting plate. When the limiting plate is horizontal, the end of the locking rod can extend to the top of the limiting plate and fit against the top of the limiting plate.

[0020] Furthermore: the mounting block includes a hinge frame one fixedly mounted on one side of the bearing seat, and a hinge block one hinged to the side of the hinge frame one away from the bearing seat via a hinge shaft one.

[0022] Furthermore: the top of the hinge block 2 is provided with an installation cavity, and the side of the connecting plate 1 away from the telescopic rod 2 is integrally formed with a horizontal rotating shaft 2. The connecting plate 1 is rotatably mounted on the hinge block 2 through the rotating shaft 2, and the end of the rotating shaft 2 extends into the installation cavity. An adjusting component acting on the rotating shaft 2 is installed on the hinge block 2 and located in the installation cavity, which is used to make the rotating shaft 2 rotate or stop rotating on the hinge block 2.

[0023] Furthermore: the adjusting component includes a worm gear two coaxially fixed to the rotating shaft two, and a worm gear two meshing with the worm gear two is rotatably mounted on the inner side wall of the mounting cavity;

[0024] A level is fixedly installed on the top of the second connecting plate.

[0025] This invention provides a collision level detection mechanism for a grinding worktable. Compared with the prior art, it has the following advantages:

[0026] 1. When testing the impact level of the grinding table, when the grinding disc descends and comes into contact with the stress plate, the pressure generated by the impact on the stress plate is higher than the stress value of the stress plate, causing the stress plate to break. The broken stress plate remains in the receiving groove of the mounting base, so that the operator does not need to clean the surface of the grinding table, which is convenient for use.

[0027] 2. By designing the limiting component, the stress plate placed on top of the tray is limited, effectively preventing the stress plate from tilting and reducing the detection accuracy when the control grinding disc descends and comes into contact with the stress plate;

[0028] 3. The design of the fasteners achieves a fixed effect between the limiting plate and the limiting seat. When the stress plate needs to be installed, when the limiting plate rotates to a vertical position on the limiting seat, the end of the locking rod is inserted into the locking hole and engages with the limiting plate to position the limiting plate, facilitating the installation of the stress plate. After the stress plate is installed, the limiting plate rotates back to a horizontal position. When limiting the stress plate placed in the receiving groove, the end of the locking rod moves above the limiting plate and fits against the top of the limiting plate to limit the stress plate, improving the limiting effect of the limiting plate on the stress plate.

[0040] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are described clearly and completely. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Example 1

[0042] To address the technical problems in the background section, the following collision level detection mechanism for a grinding worktable is provided:

[0043] Combination Figures 1-9 As shown, the present invention provides a collision level detection mechanism for a grinding workbench, comprising:

[0044] Support 1;

[0045] Positioning mechanism 2 is installed on one side of the support seat 1. Positioning mechanism 2 is used to fix the support seat 1 to one side of the grinding table 3. A grinding disc 31 is movably installed on the grinding table 3 and above it. It is worth noting that the installation method between the grinding disc 31 and the grinding table 3 is an existing structure and is known to those skilled in the art. It will not be described in detail here. The positioning mechanism 2 includes a mounting block 21 installed on one side of the support seat 1. A guide rail 22 is installed on the end of the mounting block 21 away from the support seat 1. A clamping plate 23 is slidably installed on the guide rail 22 along the direction of the mounting block 21. A driving component 24 for driving the clamping plate 23 to slide is installed on the guide rail 22.

[0046] The lifting mechanism 4 is installed on the support seat 1. A rotation adjustment component 5 is installed on the top of the lifting mechanism 4, and a mounting seat 6 is installed on the top of the rotation adjustment component 5. The lifting mechanism 4 is used to raise and lower the height of the rotation adjustment component 5, and the rotation adjustment component 5 is used to adjust the position of the mounting seat 6 so that the mounting seat 6 is located outside the grinding table 3 or between the grinding table 3 and the grinding disc 31.

[0047] The stress plate 7 is provided with a receiving groove 61 on the top of the mounting base 6. Four vertical spring telescopic rods 62 are fixed in a circular array on the bottom wall of the receiving groove 61. A support plate 63 is fixedly installed on the top of the four spring telescopic rods 62 and inside the receiving groove 61. The cross-section of the support plate 63 is cross-shaped. A pressure sensor 64 is fixedly installed on the bottom wall of the receiving groove 61 and is in contact with the support plate 63. It is worth noting that the pressure sensor 64 is communicatively connected to a PLC control system, and the PLC control system is communicatively connected to an external display screen. The stress plate 7 is placed on the top of the support plate 63 and inside the receiving groove 61. It is worth noting that when the stress plate 7 is placed inside the receiving groove 61, the top of the stress plate 7 and the top of the mounting base 6 are on the same horizontal plane.

[0048] The limiting component 8 is mounted on the mounting base 6 and is used to limit the stress plate 7 placed on top of the support plate 63.

[0049] When performing collision level testing on the grinding table, the testing mechanism is moved to one side of the grinding table 3, so that the mounting block 21 and the clamping plate 23 are located on both sides of the grinding table 3. The testing mechanism is pushed so that the guide rail 22 contacts the grinding table 3. The driving component 24 moves the clamping plate 23 closer to the grinding table 3 on the guide rail 22, thereby clamping the grinding table 3 with the clamping plate 23 and the mounting block 21, achieving the positioning effect of the testing mechanism. At this time, the mounting seat 6 is located outside the grinding table 3. The height of the rotating adjustment component 5 is adjusted by the lifting mechanism 4 so that the height of the mounting seat 6 is between the grinding table 3 and the grinding disc 31. At this time, the mounting seat 6 is moved between the grinding table 3 and the grinding disc 31 by rotating the adjustment component 5. The stress plate 7 is placed on the support plate 63 in the receiving groove 61. At this time, the position of the grinding disc 31 is controlled to descend and contact the stress plate 7. The grinding disc 31 impacts the stress plate 7. When impacted, the support plate 63 is pushed downward along the four spring telescopic rods 62. The pressure sensor 64 detects a change in the force and sends it to the PLC control system. The PLC control system converts this into a pressure value and feeds it back to the external display screen. By observing the measured pressure value, the operator can detect the impact level of the grinding table. When the grinding disc 31 descends and contacts the stress plate 7, the pressure generated by the collision with the stress plate 7 is higher than the stress value of the stress plate 7, causing the stress plate 7 to break. The broken stress plate 7 remains in the receiving groove 61 of the mounting base 6, so the operator does not need to clean the surface of the grinding table 3, which is convenient for use. Through the design of the limiting component 8, the stress plate 7 placed on top of the support plate 63 is limited, which effectively avoids the stress plate 7 tilting and reducing the detection accuracy when the grinding disc 31 descends and contacts the stress plate 7.

[0050] In this embodiment, the driving component 24 includes a threaded rod 241 that is horizontally rotatably mounted on the guide rail 22. The threaded rod 241 is threadedly connected to the clamping plate 23. A motor 242 for driving the threaded rod 241 to rotate is fixedly mounted on the guide rail 22. In use, the motor 242 is turned on, and the operation of the motor 242 can drive the threaded rod 241 to rotate on the guide rail 22, thereby driving the clamping plate 23 to slide on the guide rail 22 towards or away from the mounting block 21, which is convenient for control.

[0051] In this embodiment, the lifting mechanism 4 includes telescopic rods 41, a lifting plate 42, a housing 43, a threaded column 44, and a driving component 45. Multiple vertically oriented telescopic rods 41 are fixedly installed on the top of the bearing seat 1. The lifting plate 42 is fixedly connected to the top of four telescopic rods 41. A vertically oriented housing 43 is fixedly installed on the bottom of the lifting plate 42. A vertically oriented threaded column 44 is rotatably installed on the bearing seat 1. The top of the threaded column 44 is threaded through the bottom of the housing 43. The driving component 45... Installed on the support seat 1 and connected to the threaded post 44, the driving component 45 is used to make the threaded post 44 rotate or stop rotating on the support seat 1. In use, the threaded post 44 is rotated on the support seat 1 by the driving component 45. The threaded post 44 is threadedly connected to the housing 43, so the housing 43 can drive the lifting plate 42 to move closer or further away from the support seat 1 along the four telescopic rods 41, thereby achieving the effect of adjusting the height position of the lifting plate 42, and thus achieving the effect of raising and lowering the height position of the rotation adjustment component 5.

[0052] Example 2

[0053] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:

[0054] In this embodiment, the driving component 45 includes a rotating rod 451 rotatably mounted on the support seat 1. The end of the rotating rod 451 is connected to the threaded column 44 through a bevel gear assembly 452. In use, rotating the rotating rod 451 can drive the threaded column 44 to rotate on the lifting plate 42 through the bevel gear assembly 452, which is simple to operate.

[0055] In this embodiment, the rotation adjustment assembly 5 includes a vertically oriented rotating shaft 51 rotatably mounted on a lifting plate 42. A connecting block 52 is mounted on the top of the rotating shaft 51. A worm gear 53 is coaxially fixed to the rotating shaft 51. A worm gear 54 meshing with the worm gear 53 is rotatably mounted on the lifting plate 42. A connecting plate 55 is mounted on one side of the connecting block 52. Horizontally oriented telescopic rods 56 are symmetrically fixed on the side of the connecting plate 55 away from the connecting block 52. Connecting plates 57 are fixedly connected to the ends of the two telescopic rods 56. A drive rod 58 connected to the connecting plate 57 is fixedly mounted on the connecting plate 55. The mounting seat 6 is fixedly connected to the connecting plate 57. In use, after the bearing seat 1 is fixed to one side of the grinding table 3 by the positioning mechanism 2, the mounting seat 6 is positioned on the grinding table 3. On one side, after adjusting the height of the lifting plate 42 by rotating the rotating rod 451, so that the height of the mounting seat 6 is between the grinding table 3 and the grinding disc 31, rotating the worm gear 54 will drive the rotating shaft 51 to rotate on the lifting plate 42 through the worm wheel 53. This will cause the mounting seat 6 to rotate around the rotating shaft 51 to the side of the connecting block 52 closer to the grinding disc 31. At this time, with the cooperation of the drive rod 58, the mounting seat 6 can move closer to or further away from the connecting block 52 along the two telescopic rods 56, thus moving the mounting seat 6 to the area between the grinding table 3 and the grinding disc 31. Conversely, rotating the worm gear 54 in the opposite direction will drive the rotating shaft 51 to rotate in the opposite direction on the lifting plate 42 through the worm wheel 53, causing the mounting seat 6 to rotate around the rotating shaft 51 to the outside of the grinding table 3, thus achieving the effect of adjusting the position of the mounting seat 6.

[0056] In this embodiment, the limiting assembly 8 includes a limiting seat 81, a limiting plate 82, and a resetting member 83. The limiting seat 81 is fixedly installed on the top of the mounting base 6 and on both sides of the receiving groove 61. The limiting plate 82 is hinged to the limiting seat 81. A resetting member 83 connected to the limiting plate 82 is installed on the limiting seat 81, which is used to rotate and reset the limiting plate 82 on the limiting seat 81, so that the limiting plate 82 is horizontal. When the limiting plate 82 is horizontal, the end of the limiting plate 82 extends above the receiving groove 61, and the bottom of the limiting plate 82 is in contact with the top of the mounting base 6. Specifically, the resetting member 83 is a coil spring. A fixed shaft is fixed on the limiting seat 81. The limiting plate 82 is sleeved outside the fixed shaft and hinged to the limiting seat 81. The coil spring is sleeved outside the fixed shaft, and both ends of the coil spring are respectively connected to the limiting plate 82 and the fixed shaft. When the stress plate 7 is installed, a force is applied to the two limiting plates 82, causing them to rotate vertically on the two limiting seats 81. The ends of the two limiting plates 82 are located outside the receiving groove 61. At this time, both coil springs deform under stress, and the stress plate 7 is placed on top of the support plate 63 in the receiving groove 61, thus achieving the installation effect of the stress plate 7. After the stress plate 7 is installed, the force applied to the two limiting plates 82 is released, and the two coil springs return to their natural state, causing the two limiting plates 82 to rotate back to a horizontal position on the two limiting seats 81. At this time, the ends of the limiting plates 82 extend above the receiving groove 61, and the bottom of the limiting plates 82 is in contact with the top of the mounting base 6, thereby achieving the limiting effect of the stress plate 7 placed in the receiving groove 61.

[0057] Example 3

[0058] like Figures 1-9 As shown, based on the above embodiments, this embodiment further provides the following:

[0059] In this embodiment, a fixing member 9 acting on the limiting plate 82 is installed on the limiting seat 81. This fixing member 9 is used to fix or remove the fixing between the limiting plate 82 and the limiting seat 81. The fixing member 9 includes a fixing frame 91 fixedly installed on one side of the limiting seat 81. A fixing frame 92 is fixedly installed on the top of the fixing frame 91 and on the side near the limiting seat 81. A locking rod 93 extends horizontally through the fixing frame 92. A locking hole 821 is provided on the side of the limiting plate 82 near the fixing frame 91. A spring telescopic rod 94 fixedly connected to the fixing frame 91 is fixedly installed on the side of the locking rod 93 away from the limiting plate 82. When the limiting plate 82 is vertical, the end of the locking rod 93 can be inserted into the locking hole 821 and engaged with the limiting plate 82. When the limiting plate 82 is horizontal, the end of the locking rod 93 can extend above the limiting plate 82 and fit against the top of the limiting plate 82. Through the design of the fixing member 9, the fixing effect between the limiting plate 82 and the limiting seat 81 is achieved, thus facilitating the fixing between the limiting plate 82 and the limiting seat 81. In use, when the stress plate 7 needs to be installed, when the limiting plate 82 is rotated to a vertical position on the limiting seat 81, the locking rod 93 is pulled to move its end into the fixing frame 92. This causes the end of the locking rod 93 to move to the outside of the limiting plate 82. At this time, the second spring telescopic rod 94 deforms. After the end of the locking rod 93 moves to the outside of the limiting plate 82, the limiting plate 82 can rotate to a vertical position on the limiting seat 81. Then, the force on the locking rod 93 is released, and the second spring telescopic rod 94 returns to its natural state, thus pushing the locking rod 93 to move within the fixed frame 92, so that the end of the locking rod 93 is inserted into the locking hole 821 and locked with the limiting plate 82, thereby positioning the limiting plate 82. Similarly, the other limiting plate 82 is positioned vertically, which facilitates stress adjustment. After the stress plate 7 is installed, pull the lever 93 so that its end moves to the outside of the locking hole 821. The coil spring returns to its natural state, so that the limiting plate 82 can rotate and reset to a horizontal position, limiting the stress plate 7 placed in the receiving groove 61. At this time, the force on the lever 93 is released, and the spring telescopic rod 94 returns to its natural state, pushing the lever 93 to move within the fixed frame 92, so that the end of the lever 93 moves above the limiting plate 82 and fits against the top of the limiting plate 82, thereby limiting the limiting plate 82 and improving the limiting effect of the limiting plate 82 on the stress plate 7.

[0060] In this embodiment, the mounting block 21 includes a hinge frame 211 fixedly mounted on one side of the support seat 1. A hinge block 212 is hinged to the side of the hinge frame 211 away from the support seat 1 via a hinge shaft. The guide rail 22 is fixedly connected to the hinge block 212. The hinge shaft is horizontal. A second motor 213 for driving the hinge shaft to rotate is fixedly mounted on the hinge frame 211. The connecting block 52 includes a hinge frame 521 fixedly mounted on the top of the rotating shaft 51. A hinge block 522 is hinged to the top of the hinge frame 521 via a hinge shaft. A connecting plate 55 is mounted on one side of the hinge block 522. The hinge shaft is horizontal. A motor 523 for driving the hinge shaft 2 to rotate is fixedly installed on the hinge frame 2 521. When the testing mechanism is not in use and is stored, the motor 523 first rotates the hinge shaft 2 on the hinge frame 2 521, driving the hinge block 2 522 to rotate on the hinge frame 2 521, so that the mounting base 6 is located directly above the hinge block 2 522. Then, the motor 213 rotates the hinge shaft 1 on the hinge frame 1 211, driving the hinge block 1 212 to rotate, so that the guide rail 22 is located directly above the hinge block 1 212, thereby reducing the lateral cross-sectional width of the testing mechanism, which is beneficial for storing the testing mechanism.

[0061] In this embodiment, the top of the second hinge block 522 has a mounting cavity 5221. A horizontally shaped rotating shaft 551 is integrally formed on the side of the first connecting plate 55 away from the second telescopic rod 56. The first connecting plate 55 is rotatably mounted on the second hinge block 522 via the rotating shaft 551, and the end of the rotating shaft 551 extends into the mounting cavity 5221. An adjusting member 524 is installed on the second hinge block 522 and located within the mounting cavity 5221, acting on the rotating shaft 551. This adjusting member 524 is used to rotate or stop the rotating shaft 551 on the second hinge block 522. The first connecting plate 55 is rotatably mounted on the second hinge block 522 via the rotating shaft 551. When the stress plate 7 collides with the grinding disc 31 on the second connecting block 522, and the stress plate 7 breaks due to the impact of the grinding disc 31, the fragments of the stress plate 7 fall into the receiving groove 61 through the gap on the support plate 63. When cleaning the fragments of the stress plate 7 in the receiving groove 61, the second rotating shaft 551 is rotated on the second connecting block 522 by the adjusting component 524, so that the mounting base 6 can be flipped by the second connecting plate 57, so that the opening end of the receiving groove 61 is located at the bottom of the mounting base 6, and the fragments in the receiving groove 61 can be poured out downwards, thus facilitating the cleaning of the stress plate 7 fragments collected in the receiving groove 61.

[0062] In this embodiment, the adjusting member 524 includes a worm gear 5241 coaxially fixed to the rotating shaft 551. A worm 5242 meshing with the worm gear 5241 is rotatably mounted on the inner wall of the mounting cavity 5221. In use, rotating the worm 5242 drives the rotating shaft 551 to rotate on the hinge block 522 via the worm gear 5241. The operation is simple. Because the meshing of the worm gear 5241 and the worm 5242 has a self-locking property, the worm gear 5241 remains stationary when the worm 5242 is not rotated. 1. No rotation occurs, thus the pivot 551 and hinge block 522 can be fixed together for easy use; a level 571 is fixedly installed on the top of the connecting plate 57. Specifically, the top of the connecting plate 57 and the top of the mounting base 6 are on the same horizontal plane. Through the design of the level 571, the tilt state of the top of the connecting plate 57 can be observed by observing the level 571, which makes it easy for the staff to adjust the mounting base 6 so that its top is horizontal, making it easy to use.
