Description
Technical Field
[0001] The present invention relates to the technical field of louver grinding discs, and specifically to a preparation device and method for a sharp louver grinding disc. Background Art
[0002] A grinding disc is a key component used in industrial production for processing techniques such as grinding and polishing. In many fields, such as mechanical manufacturing, optical glass processing, and electronic component manufacturing, a grinding process is required to obtain a surface with high precision and quality.
[0003] In the preparation process of traditional sharp louver grinding discs, in the glue dispensing link, due to the lack of a precise control mechanism, it is difficult for the preparation device to adjust the position of the glue gun according to the size of the substrate. As a result, the glue is extremely likely to deviate from the ideal area during glue dispensing, resulting in a large amount of glue accumulation. On the contrary, if the glue supply is insufficient or the flow is uneven, the glue will be difficult to evenly cover the surface of the substrate, causing the abrasive to not fully adhere. Summary of the Invention

The clamping rod passes through the movable disk and extends to the upper end, and the outer diameter of the clamping rod matches the aperture of the through hole at the center of the grinding disk.
[0008] Preferably, one end of the connecting pipe A is connected to the air pump. An airbag is arranged inside the connecting pipe A. One end of the connecting pipe A passes through the connecting pipe A and extends to the inside to be connected to the airbag. The storage tank is embedded inside the operating table. A ejector rod is movably connected inside the air pressure pipe A. One end of the ejector rod located outside the air pressure pipe A is fixedly connected to a rack.
[0009] Preferably, one end of the gear close to the connecting pipe C is fixedly connected to a connecting rod. The connecting rod passes through the connecting pipe C and extends to the inside to be connected to the valve. The gear meshes with the rack.
[0010] Preferably, three groups of air inlet pipes B are arranged at the lower end of the movable disk.

The other end of the spring A is fixedly connected to the inner wall of the air inlet pipe B. One end of the air inlet pipe B is fixedly connected to a connecting pipe B. The other end of the connecting pipe B is connected to a guiding pipe.
[0011] Preferably, a limiting rod is movably connected inside the guiding pipe. The limiting rod passes through the operating table and extends to the upper end. The limiting rod is located inside the sliding groove.
[0012] Preferably, one end of the air pressure pipe B is connected to the connecting pipe C. The other end of the connecting pipe C is connected to a hot air blower.

One end of the push rod located inside the air pressure pipe B is fixedly connected to a spring. The other end of the spring is connected to the inner wall of the air pressure pipe B.
[0013] A preparation method of a sharpness louver grinding disk includes the following steps: Step 1: Before use, the staff connects the base body to the clamping rod and places it on the upper end of the movable disk. At this time, the glue gun is pushed downward by the electric push rod. When the glue gun moves downward, the grinding sheet will contact the base body, thereby squeezing the base body to descend. When the base body descends, the first detection rod and the second detection rod will be synchronously squeezed to descend. When the second detection rod descends, air pressure will enter the inside of the air inlet pipe B. When the second detection rod enters the inside of the air inlet pipe B, it will squeeze the air pressure inside the air inlet pipe B into the guiding pipe, causing the limiting rod to move upward, so that the support frame is limited by the limiting rod; Step 2: When the first detection rod descends, it will enter the air inlet pipe A, thereby squeezing the gas into the airbag, causing the airbag to expand. When the air pressure reaches a certain pressure inside the limiting rod, the ejector rod will be pushed out through the air pressure pipe A, thereby rotating the gear through the rack, and then closing the valve inside the connecting pipe C; Step 3: After preparation is completed, at this time, drive the clamping rod to rotate through the motor. When the clamping rod rotates, it will drive the base to rotate synchronously. At this time, the glue gun starts dispensing glue. When the base rotates, the grinding sheet will polish the surface of the base through friction. Compared with the prior art, the beneficial effects of the present invention are as follows: When the present invention dispenses glue, the motor will drive the clamping rod to rotate. Thus, when the clamping rod rotates, it will drive the base to rotate synchronously. When the base rotates, the grinding sheet will pre-polish the position where the glue is dispensed, and the grinding sheet will also evenly level the glue after dispensing. Therefore, pre-polishing can remove impurities, oil stains, oxide layers, etc. on the surface of the base, making the surface of the base cleaner and rougher, increasing the contact area between the glue and the base, improving the bonding force between the glue and the base, ensuring the firm bonding of the grinding layer and the base. At the same time, the uniform glue layer can make the abrasive better embedded in the glue and distributed more evenly.
[0014] After the connecting pipe C conveys hot air into the air gun, it will heat the glue, and control the heating time according to the size of the base, and can accurately adjust the curing state of the glue according to actual needs, ensuring that the grinding disc has good bonding performance and mechanical properties. At the same time, for grinding discs of the same specification, a fixed heating time can ensure that the performance of each grinding disc is relatively consistent, reducing the fluctuation of product quality.
[0015] When the pump is turned on, the hot air blower will be turned on synchronously. After the hot air blower is turned on, the hot air will enter the air pressure pipe B through the connecting pipe C. After the air pressure enters the air pressure pipe B, the air pressure pipe B will push out the push rod. Since the push rod is connected to the support frame and limited by the above-mentioned limiting rod, the position of the glue gun is controlled according to the size of the base, so that the glue dispensing position is always at the center of the base, thereby ensuring that the glue is evenly distributed at the center of the base, avoiding vibration and imbalance caused by the center of gravity deviation during subsequent use, thus improving the grinding accuracy and quality. At the same time, when the glue gun dispenses glue at the center of the base, the glue can be more evenly distributed on the surface of the base, preventing glue overflow.

Detailed implementation manners
[0018] 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 will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected 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.
[0019] The present invention provides a preparation device for a sharpness louver grinding disc, including an operating table 1, a support frame 2 is installed at the upper end of the operating table 1, a glue gun 4 is lifted on one side of the support frame 2, and a grinding disc 5 is installed on one side of the glue gun 4; A movable disc 6 is installed at the upper end of the operating table 1, a first detection rod 9 and a second detection rod 10 are installed inside the movable disc 6, the lower end of the first detection rod 9 is connected to an intake pipe A 11, one end of the intake pipe A 11 is connected to a connecting pipe A 12, one end of the connecting pipe A 12 is connected to a storage tank 19, one end of the storage tank 19 is installed with an air pressure pipe A 20, one end of the air pressure pipe A 20 is connected to a rack 22, two groups of air guns 25 are installed at the upper end of the operating table 1, a connecting pipe C 24 is connected to one side of the air gun 25, and a gear 23 is installed outside the connecting pipe C 24; The lower end of the second detection rod 10 is connected to an intake pipe B 14, one end of the intake pipe B 14 communicates with a guiding pipe 17, and an air pressure pipe B 26 is installed on one side of the operating table 1.
[0020] In an optional embodiment, a chute is opened at the upper end of the operating table 1, the support frame 2 is located inside the chute, an electric push rod 3 is installed at the upper end of the support frame 2, one end of the electric push rod 3 is connected to the glue gun 4, and the grinding disc 5 is fixedly connected to one end of the glue gun 4. During use, the glue gun 4 and the grinding disc 5 are lifted through the control of the electric push rod 3, and the initial position of the grinding disc 5 and the movable disc 6 are in the same vertical plane.
[0021] In an alternative embodiment, a motor 7 is fixedly connected to the center of the lower end of the movable disk 6. The output end of the motor 7 is rotatably connected to a clamping rod 8. The clamping rod 8 passes through the movable disk 6 and extends to the upper end. The outer diameter of the clamping rod 8 is consistent with the aperture of the through hole at the center of the grinding disk. Before use, the staff connects the clamping rod 8 to the through hole at the center of the base body. At this time, the base body descends due to the downward pressure of the grinding sheet 5. When the base body descends, it will synchronously squeeze the first detection rod 9 and the second detection rod 10 to descend. When the first detection rod 9 descends, it will squeeze the air pressure inside the air inlet pipe A11. When dispensing glue, the motor 7 will drive the clamping rod 8 to rotate. Thus, when the clamping rod 8 rotates, it will drive the base body to rotate synchronously. When the base body rotates, the grinding sheet 5 will pre-grind the position where the glue is dispensed, and the grinding sheet 5 also evenly levels the glue after dispensing. Thus, pre-grinding can remove impurities, oil stains, oxide layers, etc. on the surface of the base body, making the surface of the base body cleaner and rougher, increasing the contact area between the glue and the base body, improving the bonding force between the glue and the base body, ensuring the firm bonding of the grinding layer and the base body. At the same time, the uniform glue layer can make the abrasive better embedded in the glue and more evenly distributed.
[0022] In an alternative embodiment, one end of the connecting pipe A12 is connected to an air pump. An airbag 13 is arranged inside the connecting pipe A12. One end of the connecting pipe A12 passes through the connecting pipe A12 and extends to the inside to be connected to the airbag 13. The storage tank 19 is embedded in the operating table 1. A push rod 21 is movably connected inside the air pressure pipe A20. One end of the push rod 21 located outside the air pressure pipe A20 is fixedly connected to a rack 22. After the gas inside the air inlet pipe A11 is squeezed, it will enter the inside of the airbag 13. Thus, the airbag 13 will expand, and the size of the grinding disk determines the number of airbags 13 that expand. At this time, the air pump is turned on. After the airbag 13 expands, it will change the inner diameter of the connecting pipe A12, thereby changing the speed of the connecting pipe A12 for delivering air pressure, and then controlling the speed of air pressure entering the storage tank 19 according to the size of the base body. After the air pressure enters the storage tank 19 and reaches a certain amount, it will push the push rod 21 inside the air pressure pipe A20 upward. When the push rod 21 rises, it will synchronously drive the rack 22 to rise.
[0023] In an alternative embodiment, a connecting rod is fixedly connected to one end of the gear 23 close to the connecting pipe C24. The connecting rod passes through the connecting pipe C24 and extends to the inside to be connected to the valve. The gear 23 meshes with the rack 22. The connecting pipe C24 conveys hot air into the inside of the air gun 25 to heat the glue. Moreover, as described above, when controlling the air pressure entering the storage tank 19 by the size of the base, when the rack 22 rises, it will drive the gear 23 to rotate, thereby closing the valve at the connection between the connecting pipe C24 and the air gun 25, stopping the heating, and further controlling the heating time according to the size of the base. The curing state of the glue can be precisely adjusted according to actual needs to ensure that the grinding disc has good bonding performance and mechanical properties. At the same time, for grinding discs of the same specification, a fixed heating time can ensure that the performance of each grinding disc is relatively consistent, reducing the fluctuation of product quality.
[0024] In an alternative embodiment, three groups of intake pipes B14 are provided at the lower end of the movable disc 6. One end of the second detection rod 10 located inside the intake pipe B14 is fixedly connected to a spring A15, and the other end of the spring A15 is fixedly connected to the inner wall of the intake pipe B14. One end of the intake pipe B14 is fixedly connected to a connecting pipe B16, and the other end of the connecting pipe B16 is connected to the guide pipe 17. When the second detection rod 10 descends, it will enter the inside of the intake pipe B14. After the second detection rod 10 enters the inside of the intake pipe B14, it will squeeze the air pressure inside the intake pipe B14 to enter the inside of the guide pipe 17 through the connecting pipe B16. After removing the base, the second detection rod 10 will automatically reset by the force of the spring A15.
[0025] In an alternative embodiment, a limiting rod 18 is movably connected inside the guide pipe 17. The limiting rod 18 passes through the operating table 1 and extends to the upper end. The limiting rod 18 is located inside the sliding groove. After the air pressure enters the inside of the guide pipe 17, it will push the limiting rod 18 upward.
[0026] In an alternative embodiment, one end of the air pressure tube B26 is connected to the connecting tube C24, and the other end of the connecting tube C24 is connected to a hot air blower. A push rod 27 is movably connected inside the air pressure tube B26. One end of the push rod 27 located outside is connected to the support frame 2. One end of the push rod 27 located inside the air pressure tube B26 is fixedly connected to a spring 28, and the other end of the spring 28 is connected to the inner wall of the air pressure tube B26. When the pump is turned on, the hot air blower will be turned on synchronously. After the hot air blower is turned on, the hot air will enter the inside of the air pressure tube B26 through the connecting tube C24. After the air pressure enters the inside of the air pressure tube B26, the air pressure tube B26 will push out the push rod 27. Since the push rod 27 is connected to the support frame 2 and is limited by the above-mentioned limiting rod 18 at the same time, the position of the glue gun 4 is controlled according to the size of the substrate, so that the glue application point is always located at the center of the substrate, thereby ensuring that the glue is evenly distributed at the center of the substrate, avoiding vibration and imbalance caused by the center of gravity shift during subsequent use, thereby improving the grinding accuracy and quality. At the same time, when the glue gun is located at the center of the substrate for glue application, the glue can be more evenly distributed on the surface of the substrate, preventing glue overflow. After use, the grinding disc 5 will be reset by the electric push rod 3, and the pump and the hot air blower will stop supplying air. Then, the push rod 27 will automatically reset by the force of the spring 28, and its first detection rod 9 will be squeezed back into the intake pipe A11 by the tension of the airbag 13, thereby controlling the reset of the first detection rod 9.
[0027] This embodiment also discloses a preparation method of a sharpness louver grinding disc, including the following steps: Step 1: Before use, the staff connects the substrate to the clamping rod 8 and places it on the upper end of the movable disc 6. At this time, the glue gun 4 is pushed downward by the electric push rod 3. When the glue gun 4 moves downward, the grinding disc 5 will contact the substrate, thereby squeezing the substrate to descend. When the substrate descends, the first detection rod 9 and the second detection rod 10 will be synchronously squeezed to descend. When the second detection rod 10 descends, the air pressure will enter the intake pipe B14. When the second detection rod 10 enters the intake pipe B14, it will squeeze the air pressure inside the intake pipe B14 into the guide pipe 17, causing the limiting rod 18 to move upward, so that the support frame 2 is limited by the limiting rod 18; Step 2: When the first detection rod 9 descends, it will enter the intake pipe A11, thereby squeezing the gas into the airbag 13, causing the airbag 13 to expand. When the air pressure reaches a certain pressure inside the limiting rod 18, the ejector rod 21 will be pushed out through the air pressure tube A20, thereby rotating the gear 23 through the rack 22, and then closing the valve inside the connecting tube C24; Step 3: After preparation is completed, at this time, the clamping rod 8 is driven to rotate by the motor 7. When the clamping rod 8 rotates, it will drive the substrate to rotate synchronously. At this time, the glue gun 4 starts to apply glue. When the substrate rotates, the grinding disc 5 will polish the surface of the substrate through friction.
[0028] Working principle: Before use, the staff connects the clamping rod 8 to the through hole at the center of the base body. During use, the glue gun 4 and the grinding disc 5 are lifted and lowered under the control of the electric push rod 3. At this time, the base body descends as the grinding disc 5 presses down. When the base body descends, it will simultaneously squeeze the first detection rod 9 and the second detection rod 10 to descend. When the first detection rod 9 descends, it will squeeze the air pressure inside the air inlet pipe A11. When dispensing glue, the motor 7 will drive the clamping rod 8 to rotate, so that when the clamping rod 8 rotates, it will drive the base body to rotate synchronously. When the base body rotates, the grinding disc 5 will pre-grind the position where the glue is to be dispensed, and the grinding disc 5 also evenly levels the glue after dispensing; After the gas inside the air inlet pipe A11 is squeezed, it will enter the airbag 13, so that the airbag 13 will expand, and the size of the grinding disc determines the number of airbags 13 that expand. At this time, the air pump is turned on. After the airbag 13 expands, it will change the inner diameter of the connecting pipe A12, so that the speed of the connecting pipe A12 transporting air pressure changes, and then control the speed of the air pressure entering the storage tank 19 according to the size of the base body. After the air pressure enters the storage tank 19 and reaches a certain amount, it will push up the ejector rod 21 inside the air pressure pipe A20. When the ejector rod 21 rises, it will simultaneously drive the rack 22 to rise. The connecting pipe C24 transports hot air into the air gun 25 to heat the glue, and when the rack 22 rises, it will drive the gear 23 to rotate, so as to close the valve at the connection between the connecting pipe C24 and the air gun 25, thus stopping the heating, and then control the heating time according to the size of the base body; When the second detection rod 10 descends, it will enter the air inlet pipe B14. After the second detection rod 10 enters the air inlet pipe B14, it will squeeze the air pressure inside the air inlet pipe B14 to enter the guide pipe 17 through the connecting pipe B16. After the air pressure enters the guide pipe 17, it will push up the limit rod 18. When the pump is turned on, the hot air blower will be turned on simultaneously. After the hot air blower is turned on, the hot air will enter the air pressure pipe B26 through the connecting pipe C24. After the air pressure enters the air pressure pipe B26, the air pressure pipe B26 will push out the push rod 27. Since the push rod 27 is connected to the support frame 2 and is limited by the limit rod 18 at the same time, the position of the glue gun 4 is controlled according to the size of the base body, so that the glue dispensing position is always at the center of the base body; After use, the grinding disc 5 will be reset by the electric push rod 3, and the pump and the hot air blower will stop supplying air. Then the push rod 27 will automatically reset by the force of the spring 28. The first detection rod 9 will squeeze the air pressure back into the air inlet pipe A11 through the tension of the airbag 13 to control the reset of the first detection rod 9, and the second detection rod 10 will automatically reset by the force of the spring A15.

When the second detection rod (10) enters the inside of the air inlet pipe B (14), it will squeeze the air pressure inside the air inlet pipe B (14) into the inside of the guide pipe (17), causing the limiting rod (18) to move upward, so that the support frame (2) is limited by the limiting rod (18); Step 2: When the first detection rod (9) descends, it will enter the inside of the air inlet pipe A (11), thereby squeezing gas into the inside of the airbag (13) to make the airbag (13) expand. When the air pressure reaches a certain pressure inside the limiting rod (18), the ejector rod (21) will be pushed out through the air pressure tube A (20), thereby driving the gear (23) to rotate through the rack (22), and then closing the valve inside the connecting tube C (24); Step 3: After preparation is completed, at this time, the clamping rod (8) is driven to rotate by the motor (7). When the clamping rod (8) rotates, it will drive the base body to rotate synchronously. At this time, the glue gun (4) starts to apply glue. When the base body rotates, the grinding piece (5) will polish the surface of the base body through friction.
