Description

Technical Field

[0001] The present invention relates to the technical field of grinding workbench detection equipment, and particularly relates to a grinding workbench collision level detection mechanism. Background Art

[0002] A grinding workbench is a working platform for precision grinding and polishing, commonly found in fields such as machining, optical manufacturing, and laboratories; during the manufacturing process of liquid crystal glass substrates, the grinding workbench is used to ensure that its surface meets high-precision and flatness requirements;

[0003] When using the grinding workbench to polish the surface of a liquid crystal glass substrate, when the grinding disc on the grinding workbench descends and contacts the liquid crystal glass substrate, it will cause a collision to the liquid crystal glass substrate, which is likely to cause scratches, cracks, or unevenness on the surface of the liquid crystal glass substrate, thus affecting the product quality. Therefore, when the grinding workbench grinds and processes liquid crystal glass substrates of the same model batch, it is necessary to detect the collision level of the grinding workbench to avoid the collision of the liquid crystal glass substrate caused by the descent of the grinding disc position, resulting in scratches, cracks, or unevenness on the surface of the liquid crystal glass substrate. Currently, when detecting the collision level of the grinding workbench, it is mostly to place a test plate for detection on the grinding workbench, control the descent of the grinding disc position to contact the test plate for grinding, and then observe whether there are scratches, cracks, or unevenness on the surface of the test plate to achieve the detection effect of the collision level of the grinding workbench. Although this method can achieve the detection of the collision level of the grinding workbench, in actual use, there are still the following defects:

[0004] If the pressure generated by the collision of the grinding disc position descending and contacting the test plate is higher than the stress value of the test plate, resulting in the test plate breaking, the broken test plate remains on the surface of the grinding table, and thus it is necessary for the staff to clean the test plate waste on the surface of the grinding table, which is rather troublesome;

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

[0006] In view of the deficiencies of the prior art, the present invention provides a grinding workbench collision level detection mechanism, which solves the problems mentioned in the background art.

[0025] The present invention provides a collision level detection mechanism for a grinding workbench. Compared with the prior art, it has the following beneficial effects:

[0026] 1. When detecting the collision level of the grinding workbench, when the position of the grinding disc drops and contacts the stress plate, and the pressure generated by the collision against 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 seat. Thus, it is not necessary for the staff to clean the surface of the grinding table, which is convenient for use;

[0027] 2. Through the design of the limiting component, the effect of limiting the stress plate placed on the top of the supporting plate is realized, effectively avoiding the situation where the stress plate tilts and the detection accuracy is reduced when controlling the position of the grinding disc to drop and contact the stress plate;

[0028] 3. Through the design of the fixing component, the fixing effect between the limiting plate and the limiting seat is realized. When the stress plate needs to be installed, when the limiting plate rotates to the vertical state on the limiting seat, the end of the clamping rod is inserted into the clamping hole and is clamped with the limiting plate to position the limiting plate, which is convenient for installing the stress plate. After the stress plate is installed, the limiting plate rotates back to the horizontal state. When limiting the stress plate placed in the receiving groove, the end of the clamping rod is displaced above the limiting plate and fits with the top of the limiting plate to limit the limiting 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. Apparently, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0041] Embodiment 1

[0042] To solve the technical problems in the background art, the following grinding workbench collision level detection mechanism is provided:

[0043] Combined with Figures 1-9 As shown, a grinding workbench collision level detection mechanism provided by the present invention includes:

[0044] A bearing seat 1;

[0045] A positioning mechanism 2, which is installed on one side of the bearing seat 1. The positioning mechanism 2 is used to fix the bearing 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 should be noted that: the installation method between the grinding disc 31 and the grinding table 3 is an existing structure and belongs to the well-known technical scope of those skilled in the art, so it will not be elaborated here. The positioning mechanism 2 includes a mounting block 21 installed on one side of the bearing seat 1. One end of the mounting block 21 away from the bearing seat 1 is installed with a guide rail 22. A clamping plate 23 is slidably installed on the guide rail 22 along the direction of the mounting block 21. A driving assembly 24 for driving the clamping plate 23 to slide is installed on the guide rail 22;

[0046] A lifting mechanism 4, which is installed on the bearing seat 1. The top of the lifting mechanism 4 is installed with a rotation adjustment assembly 5. The top of the rotation adjustment assembly 5 is installed with a mounting seat 6. The lifting mechanism 4 is used to lift the height of the rotation adjustment assembly 5, and the rotation adjustment assembly 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] A stress plate 7. A receiving groove 61 is opened at the top of the mounting seat 6. Four vertically arranged spring telescopic rods 62 are fixedly arranged in a circular array on the inner bottom wall of the receiving groove 61. The tops of the four spring telescopic rods 62 are fixedly installed with a support plate 63 in the receiving groove 61. The cross section of the support plate 63 is cross-shaped. A pressure sensor 64 in contact with the support plate 63 is fixedly installed on the inner bottom wall of the receiving groove 61. It should be noted 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. A stress plate 7 is placed on the top of the support plate 63 in the receiving groove 61. It should be noted that: when the stress plate 7 is placed in the receiving groove 61, the top of the stress plate 7 is on the same horizontal plane as the top of the mounting seat 6;

[0048] A limiting component 8, which is installed on the mounting seat 6. The limiting component 8 is used to limit the stress plate 7 placed on the top of the support plate 63.

[0049] When detecting the collision level of the grinding workbench, move this detection mechanism to one side of the grinding table 3, so that the mounting block 21 and the clamping plate 23 are respectively located on both sides of the grinding table 3. Push this detection mechanism to make the guide rail 22 contact with the grinding table 3. By driving the assembly 24, the clamping plate 23 is made to approach the grinding table 3 along the guide rail 22, so as to realize clamping the grinding table 3 by the clamping plate 23 and the mounting block 21, and achieve the positioning effect of this detection mechanism. At this time, the mounting seat 6 is located outside the grinding table 3. Adjust the height of the rotation adjustment assembly 5 through the lifting mechanism 4, so that the height position of the mounting seat 6 is between the grinding table 3 and the grinding disc 31. At this time, the mounting seat 6 is displaced between the grinding table 3 and the grinding disc 31 through the rotation adjustment assembly 5. Place the stress plate 7 on the support plate 63 in the receiving groove 61. At this time, control the position of the grinding disc 31 to descend and contact the stress plate 7. When the grinding disc 31 collides with the stress plate 7, the support plate 63 is pushed to displace downward along the four spring telescopic rods 62. The force detection signal of the pressure sensor 64 changes and is then transmitted to the PLC control system, and is converted into a pressure value through the PLC control system and fed back to the external display screen. The staff can achieve the detection effect of the collision level of the grinding workbench by observing the measured pressure value. When the pressure generated by the contact between the grinding disc 31 and the stress plate 7 when the position of the grinding disc 31 descends is higher than the stress value of the stress plate 7 and causes the stress plate 7 to break, the broken stress plate 7 remains in the receiving groove 61 of the mounting seat 6, so that it is not necessary for the staff to clean the surface of the grinding table 3, which is convenient for use; through the design of the limiting component 8, the limiting effect on the stress plate 7 placed on the top of the support plate 63 is realized, effectively avoiding the situation that the stress plate 7 tilts and reduces the detection accuracy when controlling the position of the grinding disc 31 to descend and contact the stress plate 7.

[0050] In this embodiment, the driving assembly 24 includes a threaded rod 241 horizontally and rotatably installed 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 installed on the guide rail 22. When in use, control the motor 242 to start. When the motor 242 works, it can drive the threaded rod 241 to rotate on the guide rail 22, and thus can drive the clamping plate 23 to slide on the guide rail 22 to approach or move away from the mounting block 21, which is convenient for control.

[0051] In this embodiment, the lifting mechanism 4 includes a first telescopic rod 41, a lifting plate 42, a housing 43, a threaded column 44, and a driving member 45. A plurality of vertically arranged first telescopic rods 41 are fixedly installed on the top of the bearing seat 1. The tops of the four first telescopic rods 41 are fixedly connected to a lifting plate 42. A vertically arranged housing 43 is fixedly installed on the bottom of the lifting plate 42. A vertically arranged threaded column 44 is rotatably installed on the bearing seat 1. The top end of the threaded column 44 threadedly penetrates the bottom of the housing 43. The driving member 45 is installed on the bearing seat 1 and is connected to the threaded column 44. The driving member 45 is used to rotate or stop the rotation of the threaded column 44 on the bearing seat 1. During use, the driving member 45 is used to rotate the threaded column 44 on the bearing seat 1. The threaded column 44 is threadedly connected to the housing 43. Thus, the lifting plate 42 can be driven to approach or move away from the bearing seat 1 along the four first telescopic rods 41 through the housing 43, achieving the effect of adjusting the height position of the lifting plate 42, and thus achieving the lifting effect of the height position of the rotation adjustment assembly 5.

[0052] Embodiment Two

[0053] As Figures 1-9 shown, on the basis of the above embodiment, the following content is further given in this embodiment:

[0054] In this embodiment, the driving member 45 includes a rotating rod 451 rotatably installed on the bearing seat 1. The end of the rotating rod 451 is connected to the threaded column 44 through a bevel gear assembly 452. During 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, and the operation is simple.

[0055] In this embodiment, the rotation adjustment assembly 5 includes a first rotating shaft 51 that is vertically arranged and rotatably installed on the lifting plate 42. A connecting block 52 is installed at the top of the first rotating shaft 51. A first worm gear 53 is coaxially fixed on the first rotating shaft 51. A first worm 54 that meshes with the first worm gear 53 is rotatably installed on the lifting plate 42. A first connecting plate 55 is installed on one side of the connecting block 52. Horizontally arranged second telescopic rods 56 are symmetrically fixed on the side of the first connecting plate 55 away from the connecting block 52. The ends of the two second telescopic rods 56 are fixedly connected to a second connecting plate 57. A driving rod 58 connected to the second connecting plate 57 is fixedly installed on the first connecting plate 55. The mounting seat 6 is fixedly connected to the second connecting plate 57. During use, after the bearing seat 1 is fixed on one side of the grinding table 3 through the positioning mechanism 2, the mounting seat 6 is located on one side of the grinding table 3. After the height position of the lifting plate 42 is adjusted by rotating the rotating rod 451, when the height position of the mounting seat 6 is between the grinding table 3 and the grinding disc 31, at this time, by rotating the first worm 54, the first rotating shaft 51 can be driven to rotate on the lifting plate 42 through the first worm gear 53, driving the mounting seat 6 to rotate around the first rotating shaft 51 until the connecting block 52 is close to the side of the grinding disc 31. At this time, through the cooperation of the driving rod 58, the mounting seat 6 can be moved closer to or away from the connecting block 52 along the two second telescopic rods 56, driving the mounting seat 6 to move to between the grinding table 3 and the grinding disc 31. Conversely, by rotating the first worm 54 in the reverse direction, the first rotating shaft 51 can be driven to rotate in the reverse direction on the lifting plate 42 through the first worm gear 53, causing the mounting seat 6 to rotate around the first rotating shaft 51 to the outside of the grinding table 3, achieving the effect of adjusting the position of the mounting seat 6.

[0056] In this embodiment, the limiting component 8 includes a limiting seat 81, a limiting plate 82, and a resetting member 83. On the top of the mounting seat 6 and on both sides of the receiving groove 61, limiting seats 81 are fixedly installed. A limiting plate 82 is hinged on the limiting seat 81, and a resetting member 83 connected to the limiting plate 82 is installed on the limiting seat 81. It is used to rotate the limiting plate 82 back to its original position on the limiting seat 81 so that the limiting plate 82 is in a horizontal state. When the limiting plate 82 is in a horizontal state, the end of the limiting plate 82 extends above the receiving groove 61, and the bottom of the limiting plate 82 fits against the top of the mounting seat 6. Specifically, it should be noted that: 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 is hinged to the limiting seat 81. The coil spring is sleeved outside the fixed shaft, and both ends of the coil spring are fixedly connected to the limiting plate 82 and the fixed shaft respectively. During use, when the stress plate 7 is installed, forces are applied to the two limiting plates 82 respectively, so that the two limiting plates 82 rotate to a vertical state on the two limiting seats 81 respectively, so that the ends of the two limiting plates 82 are both located outside the receiving groove 61. At this time, both coil springs are deformed by the force. Place the stress plate 7 on the top of the support plate 63 in the receiving groove 61, and the installation effect of the stress plate 7 can be achieved. After the installation of the stress plate 7 is completed, the forces applied to the two limiting plates 82 are cancelled, and the two coil springs return to their natural states, so that the two limiting plates 82 rotate back to their original positions and are in a horizontal state on the two limiting seats 81 respectively. At this time, the end of the limiting plate 82 extends above the receiving groove 61, and the bottom of the limiting plate 82 fits against the top of the mounting seat 6, so that the stress plate 7 placed in the receiving groove 61 can be limited.

[0057] Embodiment Three

[0058] As Figures 1-9 shown, on the basis of the above embodiment, this embodiment further gives the following content:

[0059] In this embodiment, a fixing member 9 acting on the limiting plate 82 is installed on the limiting seat 81, which is used to fix or cancel the fixation 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 close to one side of the limiting seat 81. A clamping rod 93 is horizontally movably penetrated in the fixing frame 92. A clamping hole 821 is opened on one side of the limiting plate 82 close to the fixing frame 91. A second spring telescopic rod 94 fixedly connected to the fixing frame 91 is fixedly installed on the side of the clamping rod 93 away from the limiting plate 82. When the limiting plate 82 is in a vertical state, the end of the clamping rod 93 can be inserted into the clamping hole 821 and clamped with the limiting plate 82. When the limiting plate 82 is in a horizontal state, the end of the clamping rod 93 can extend above the limiting plate 82 and fit with 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 realized, so as to facilitate the fixation between the limiting plate 82 and the limiting seat 81. During use, when the stress plate 7 needs to be installed, when the limiting plate 82 is rotated to a vertical state on the limiting seat 81, the clamping rod 93 is pulled to displace its end into the fixing frame 92, so that the end of the clamping rod 93 is displaced outside the limiting plate 82. At this time, the second spring telescopic rod 94 deforms. After the end of the clamping rod 93 is displaced outside the limiting plate 82, the limiting plate 82 can be rotated to a vertical state on the limiting seat 81, and then the acting force on the clamping rod 93 is cancelled, and the second spring telescopic rod 94 returns to its natural state, so as to push the clamping rod 93 to displace in the fixing frame 92, so that the end of the clamping rod 93 is inserted into the clamping hole 821 and clamped with the limiting plate 82, and the limiting plate 82 can be positioned. Similarly, the other limiting plate 82 is positioned in a vertical state, so as to facilitate the installation of the stress plate 7. After the installation of the stress plate 7 is completed, the clamping rod 93 is pulled to displace its end outside the clamping hole 821, and the coil spring returns to its natural state, so that the limiting plate 82 can be rotated and reset to a horizontal state to limit the stress plate 7 placed in the receiving groove 61. At this time, the acting force on the clamping rod 93 is cancelled, and the second spring telescopic rod 94 returns to its natural state and pushes the clamping rod 93 to displace in the fixing frame 92, so that the end of the clamping rod 93 is displaced above the limiting plate 82 and fits with the top of the limiting plate 82, so as to limit the limiting plate 82 and improve the limiting effect of the limiting plate 82 on the stress plate 7.

[0060] In this embodiment, the mounting block 21 includes a first articulated frame 211 fixedly mounted on one side of the bearing seat 1. A first articulated block 212 is articulated to the side of the first articulated frame 211 away from the bearing seat 1 through a first articulated shaft. The guide rail 22 is fixedly connected to the first articulated block 212. The first articulated shaft is horizontal. A second motor 213 for driving the first articulated shaft to rotate is fixedly mounted on the first articulated frame 211. The connecting block 52 includes a second articulated frame 521 fixedly mounted on the top of the first rotating shaft 51. A second articulated block 522 is articulated to the top of the second articulated frame 521 through a second articulated shaft. The first connecting plate 55 is mounted on one side of the second articulated block 522. The second articulated shaft is horizontal. A third motor 523 for driving the second articulated shaft to rotate is fixedly mounted on the second articulated frame 521. When this detection mechanism is stored without use, first, the third motor 523 is used to rotate the second articulated shaft on the second articulated frame 521, driving the second articulated block 522 to rotate on the second articulated frame 521, so that the mounting seat 6 is located directly above the second articulated block 522. Then, the second motor 213 is used to rotate the first articulated shaft on the first articulated frame 211, driving the first articulated block 212 to rotate, so that the guide rail 22 is located directly above the first articulated block 212, thereby reducing the lateral cross-sectional width of this detection mechanism, which is beneficial to the storage of this detection mechanism.

[0061] In this embodiment, an installation cavity 5221 is formed at the top of the second articulated block 522. A second rotating shaft 551 in a horizontal shape 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 articulated block 522 through the second rotating shaft 551, and the end of the second rotating shaft 551 extends into the installation cavity 5221. An adjusting member 524 acting on the second rotating shaft 551 is mounted in the installation cavity 5221 of the second articulated block 522, and it is used to rotate or stop the rotation of the second rotating shaft 551 on the second articulated block 522. By setting that the first connecting plate 55 is rotatably mounted on the second articulated block 522 through the second rotating shaft 551, when a collision occurs between the stress plate 7 and the grinding disc 31, when the stress plate 7 is broken due to the collision of the grinding disc 31, the fragments of the stress plate 7 fall into the receiving groove 61 through the gaps on the support plate 63. When cleaning the fragments of the stress plate 7 in the receiving groove 61, the adjusting member 524 is used to rotate the second rotating shaft 551 on the second articulated block 522, so that the mounting seat 6 can be driven to flip by the second connecting plate 57, making the opening end of the receiving groove 61 located at the bottom of the mounting seat 6, and the fragments in the receiving groove 61 can be poured out downward, thereby facilitating the cleaning of the fragments of the stress plate 7 collected in the receiving groove 61.

[0062] In this embodiment, the adjusting member 524 includes a second worm gear 5241 fixedly connected coaxially with the second rotating shaft 551. A second worm 5242 meshing with the second worm gear 5241 is rotatably installed on the inner side wall of the installation cavity 5221. During use, rotating the second worm 5242 can drive the second rotating shaft 551 to rotate on the second hinge block 522 through the second worm gear 5241. The operation is simple. Since the second worm gear 5241 and the second worm 5242 are meshed and have self-locking property, when the second worm 5242 is not rotated, the second worm gear 5241 will not rotate, thus the second rotating shaft 551 and the second hinge block 522 can be fixed, which is convenient for use. A spirit level 571 is fixedly installed on the top of the second connecting plate 57. Specifically, it should be noted that the top of the second connecting plate 57 and the top of the installation base 6 are on the same horizontal plane. Through the design of the spirit level 571, the inclination state of the top of the second connecting plate 57 can be observed by observing the spirit level 571, so that it is convenient for the staff to adjust the installation base 6 to make its top horizontal, which is convenient for use.
