Description

TECHNICAL FIELD

[0001] The present application relates to the field of grinding technology, in particular to a multi-section adjustable grinding equipment for precision ceramic production. BACKGROUND

[0002] In the production and processing of precision ceramics, grinding is a key process that determines product precision and surface quality. The ceramic sheet needs to be finely polished to meet the stringent requirements of electronic components, precision instruments and other fields for ceramic size tolerance and surface finish. During the grinding process, stable fixation of the ceramic sheet is a core prerequisite. If the fixation is not stable, the ceramic sheet is prone to displacement during grinding, resulting in size deviation or surface scratches. If the fixation pressure is too high, it may cause brittle fracture of the ceramic sheet. At the same time, to improve production efficiency, multiple ceramic sheets need to be ground synchronously, and the fixation force and height need to be adjusted in multiple sections according to the thickness and specifications of the ceramic sheets to avoid the problem that a single fixation mode cannot meet different processing requirements.

[0003] Currently, the fixation methods for precision ceramic grinding mainly fall into two categories. The first category is mechanical clamping, which applies pressure to the ceramic sheet from both sides or the edge through a cylinder-driven clamp or a bolt-tightening structure to achieve rigid fixation. The other category is vacuum adsorption, which opens adsorption holes on the grinding platform and forms a negative pressure between the platform and the ceramic sheet through a vacuum pump to adsorb and fix the ceramic sheet using atmospheric pressure. For the demand of synchronous grinding of multiple pieces, some equipment uses multiple independent adsorption units to supply air through a unified vacuum pipeline, trying to achieve simultaneous fixation of multiple pieces.

[0004] However, the existing technology cannot meet the high requirements and multi-scene adaptation needs of precision ceramic grinding. The mechanical clamping method is prone to deformation or edge damage of the ceramic sheet due to uneven clamping force, and cannot adapt to irregular ceramic sheets. Although the traditional vacuum adsorption method can achieve non-destructive fixation, the maintenance of negative pressure in the adsorption passage relies on the continuous operation of the vacuum pump, which puts a large pressure on the vacuum pump. Moreover, there is a lack of multi-section adjustment capability, and the height of the adsorption platform of existing equipment is mostly fixed, which cannot be adjusted in multiple sections according to the grinding progress of the ceramic sheet. Also, it cannot independently adjust the negative pressure of multiple adsorption units, leading to unstable fixation of some ceramic sheets when multiple pieces are ground, resulting in leakage of the overall pipeline and displacement of the ceramic sheet during grinding, affecting product precision.

[0037] The present application will be further described below in connection with the embodiments.

[0038] Embodiment:

[0039] Please refer to Figure 1 - Figure 8 The present application provides a technical solution: a multi-section adjustable grinding equipment for precision ceramic production, comprising a grinding equipment shell 1, a fixed base 31 is installed inside, a plurality of modular connecting tables 2 are arranged above the fixed base 31, a ceramic piece to be polished 28 is attached above each modular connecting table 2, a vacuum suction head 7 is movably connected to the inner side of the modular connecting table 2 and used for suction of the ceramic piece to be polished 28, a time-delay vacuum breaker 8 is sealingly connected below the vacuum suction head 7, a vacuum breaking hole is arranged on the time-delay vacuum breaker 8, and the vacuum breaking hole is sealed by a vacuum breaking valve core inside the time-delay vacuum breaker 8.

[0040] A plurality of movable connection grooves 3 are formed in the inner side of the modular connection table 2, and each vacuum suction head 7 is movably arranged in the inner side of the corresponding movable connection groove 3. A plurality of lifting control grooves 4 are formed in the inner side of the grinding equipment shell 1, and each lifting control groove 4 is in communication with the corresponding movable connection groove 3. A multifunctional connection groove 5 is formed in the inner side of the grinding equipment shell 1, and the multifunctional connection groove 5 is in communication with the plurality of lifting control grooves 4. A sealing constraint shell 15 is arranged in the inner side of the lifting control groove 4. The sealing constraint shell 15 is provided with a constraint bottom plate 16 on the side close to the multifunctional connection groove 5. A vacuum sealing plate 11 is arranged in the inner side of the sealing constraint shell 15, and the vacuum sealing plate 11 is completely attached to the inner wall of the sealing constraint shell 15.

[0041] A multifunctional sensor 17 is embedded in the constraint bottom plate 16 and arranged below the vacuum sealing plate 11. An electromagnetic vacuum breaker 18 is arranged on the side of the constraint bottom plate 16 close to the multifunctional connection groove 5, and the electromagnetic vacuum breaker 18 is sealingly connected to the constraint bottom plate 16. A second one-way sealing valve 19 is arranged on the side of the electromagnetic vacuum breaker 18 close to the multifunctional connection groove 5, and the second one-way sealing valve 19 is sealingly connected to the electromagnetic vacuum breaker 18.

[0042] A fixed connection plate 20 is fixedly arranged on the side of the second one-way sealing valve 19 close to the multifunctional connection groove 5. A plurality of pressure balance holes 21 are formed in the fixed connection plate 20, and the fixed connection plate 20 is fixedly connected to the inner wall of the lifting control groove 4. The electromagnetic vacuum breaker 18 is in communication with the multifunctional connection groove 5 through the pressure balance holes 21. A plurality of sealing connection heads 22 are arranged in the inner side of the multifunctional connection groove 5, and one end of each sealing connection head 22 is connected to the corresponding fixed connection plate 20.

[0043] In specific implementation, the operator sends a start instruction to the vacuum connection pump set 26 through the grinding equipment console 30. After receiving the instruction, the vacuum connection pump set 26 starts the multiple groups of vacuum pumps inside to start pumping air in the system. At this time, under the negative pressure of the vacuum pump, the air flows along the preset air flow path, first enters from the adsorption end of the vacuum suction head 7, then passes through the delay vacuum breaker 8 sealingly connected below the vacuum suction head 7, the first one-way sealing valve 9 sealingly connected below the delay vacuum breaker 8, the lifting sleeve 10 sealingly connected below the first one-way sealing valve 9, then enters the inside of the sealing constraint shell 15 in the lifting control groove 4, and then passes through the electromagnetic vacuum breaker 18 sealingly connected to the constraint bottom plate 16, the second one-way sealing valve 19 on the side of the electromagnetic vacuum breaker 18, and is transported to the dispersion connection pipe 23. The dispersion connection pipe 23 divides the air into multiple air pumping connection pipes 24. The air passes through the sealing connection pipe 25 connected vertically by the air pumping connection pipe 24, and finally enters the vacuum connection pump set 26. Finally, the air is discharged outside the equipment through the multiple gas discharge ports 27 on the vacuum connection pump set 26.

[0044] Because the ceramic pieces 28 to be ground vary in size, and the vacuum adsorption heads 7 inside the modular connecting table 2 are arranged in an array, if the ceramic pieces 28 to be ground are placed directly on the modular connecting table 2, some vacuum adsorption heads 7 may not be completely covered. This could cause grinding fluid to enter the uncovered vacuum adsorption heads 7 during subsequent grinding, affecting the sealing performance of the vacuum system and the service life of the equipment. Therefore, before placing the ceramic pieces 28 to be ground, a suitable auxiliary barrier hollow plate 29 should be selected according to their actual size to assist in the process. The inner contour of the barrier hollow plate 29 matches the shape of the ceramic sheet 28 to be polished, while the outer dimensions can cover all the vacuum adsorption nozzles 7 that may participate in adsorption in the same group. The operator puts the auxiliary barrier hollow plate 29 on the outside of the ceramic sheet 28 to be polished, so that the lower surface of the auxiliary barrier hollow plate 29 fits against the vacuum adsorption nozzles 7 on the modular connecting table 2, thereby blocking the excess vacuum adsorption nozzles 7 in the same group, ensuring that only the vacuum adsorption nozzles 7 that participate in adsorption play a role in the subsequent vacuum adsorption process, while preventing the polishing liquid from entering the unused vacuum adsorption nozzles 7.

[0045] After installing the auxiliary barrier hollow plate 29, the operator places the ceramic piece 28 to be ground, covered with the auxiliary barrier hollow plate 29, on top of the modular connecting table 2, so that the ceramic piece 28 and the auxiliary barrier hollow plate 29 together cover the pre-set set of vacuum adsorption heads 7. At this time, the worker must ensure that the center of the ceramic piece 28 to be ground is aligned with the set of vacuum adsorption heads 7 to avoid uneven force on the ceramic piece during subsequent grinding due to initial positioning deviation, which would affect the grinding accuracy. The grinding equipment control console 30 will display a signal indicating that the placement of the ceramic piece 28 to be ground is complete. After the signal is received, a vacuuming command is sent to the vacuum connection pump unit 26 for the adsorption unit pipeline. The vacuum pump in the vacuum connection pump unit 26 corresponding to the pipeline increases the pumping force and begins to evacuate the inside of the vacuum adsorption head 7. As air is continuously extracted, the air pressure between the vacuum adsorption head 7 and the ceramic sheet 28 to be polished gradually decreases, forming a negative pressure. When the negative pressure reaches the preset adsorption pressure threshold, the ceramic sheet 28 to be polished and the auxiliary barrier hollow plate 29 are firmly adsorbed on the vacuum adsorption head 7 under the action of atmospheric pressure, completing the initial adsorption fixation.

[0046] Please see Figure 3 - Figure 8The application provides a technical scheme that comprises a first one-way sealing valve 9 which is sealingly connected below a time-delay vacuum breaker 8, the first one-way sealing valve 9 is used for blocking the gas flow to the inside of the vacuum adsorption suction head 7 and the time-delay vacuum breaker 8 in a vacuum state, a dispersion connecting pipe 23 is arranged in the inside of the multifunctional connecting groove 5, a plurality of sealing connecting heads 22 are fixedly connected to the other end of the dispersion connecting pipe 23, the dispersion connecting pipe 23 is in communication with the inner wall of the plurality of sealing connecting heads 22, a plurality of pipeline connecting grooves 6 are arranged on the back of the grinding equipment shell 1, and each pipeline connecting groove 6 is in communication with the multifunctional connecting groove 5.

[0047] The dispersion connecting pipe 23 is arranged in the inside of the multifunctional connecting groove 5, the other end of the plurality of sealing connecting heads 22 is fixedly connected to the dispersion connecting pipe 23, the dispersion connecting pipe 23 is in communication with the inner wall of the plurality of sealing connecting heads 22, the plurality of pipeline connecting grooves 6 are arranged on the back of the grinding equipment shell 1, and each pipeline connecting groove 6 is in communication with the multifunctional connecting groove 5, the inside of the pipeline connecting groove 6 is provided with a sealing connecting pipe 25, each sealing connecting pipe 25 is fixedly connected to the vertical center of the corresponding air extraction connecting pipe 24, and the sealing connecting pipe 25 is in communication with the inner wall of the air extraction connecting pipe 24.

[0048] In the specific implementation, in the process of vacuumizing, the air in the time-delay vacuum breaker 8 and the inside of the first one-way sealing valve 9 connected with the vacuum adsorption suction head 7 is also synchronously extracted, at the same time, the movable cavity is formed between the sealing constraint shell 15, the vacuum sealing plate 11 and the constraint bottom plate 16, the air in the movable cavity is gradually extracted to make the air pressure gradually decrease, the vacuum sealing plate 11 is completely attached to the inner wall of the sealing constraint shell 15, one side of the vacuum sealing plate 11 is connected with the lifting sleeve 10, under the action of the negative pressure in the movable cavity, the vacuum sealing plate 11 drives the lifting sleeve 10 connected therewith to overcome the elastic force of the reset spring 14 in the inside of the lifting sleeve 10 and slowly move to one side of the constraint bottom plate 16, the constraint bottom plate 16 is embedded with the multifunctional sensor 17, and the multifunctional sensor 17 is located directly below the vacuum sealing plate 11, when the vacuum sealing plate 11 continuously moves to the constraint bottom plate 16 under the action of the negative pressure, until the vacuum sealing plate 11 and the constraint bottom plate 16 coincide with each other and the lower surface of the vacuum sealing plate 11 is completely attached to the multifunctional sensor 17, the multifunctional sensor 17 senses the pressure signal and converts the signal into an electric signal and transmits the electric signal to the grinding equipment control console 30, after receiving the signal, the grinding equipment control console 30 judges that the movable cavity has reached a stable vacuum state at this moment and the position of the vacuum adsorption suction head 7 has been adjusted to the right position, then sends a command of stopping air extraction to the vacuum connection pump set 26, and the vacuum pump corresponding to the pipeline in the vacuum connection pump set 26 stops running.

[0049] Due to the existence of the first one-way sealing valve 9 and the second one-way sealing valve 19, external air cannot enter the inside of the movable cavity and the inside of the vacuum adsorption suction head 7, so that the movable cavity and the vacuum adsorption suction head 7 can always maintain a vacuum state, thereby maintaining the fit state of the vacuum sealing plate 11 and the constraint bottom plate 16, and the lifting sleeve 10 connected with the vacuum sealing plate 11 also remains in the current position, and the vacuum adsorption suction head 7 moves together with the lifting sleeve 10, so that the top end of the vacuum adsorption suction head 7 is parallel to the top end of the modular connection table 2, and the lower surface of the auxiliary blocking hollow plate 29 is also fitted with the top end of the modular connection table 2, completing the final adsorption and fixation of the ceramic piece 28 to be polished. According to the above process, the operator lays the remaining ceramic pieces 28 to be polished on the other group of vacuum adsorption suction heads on the modular connection table 2 in turn, and completes the adsorption and fixation of all ceramic pieces 28 to be polished.

[0050] Please refer to Figure 2 - Figure 8 The present application provides a technical solution: the lifting sleeve 10 connected and sealed below the first one-way sealing valve 9, the inside of the lifting sleeve 10 is provided with a reset spring 14, after breaking the vacuum state of the lifting sleeve 10, the lifting sleeve 10 is driven by the reset spring 14 to move to the side of the vacuum adsorption suction head 7, the side of the lifting sleeve 10 close to the multifunctional connection groove 5 is connected with the vacuum sealing plate 11, the inside of the lifting sleeve 10 is provided with a fixed support block 12, the center of the lifting sleeve 10 is provided with a fixed support rod 13, one end of the fixed support rod 13 is connected with the fixed support block 12, the inside of the lifting sleeve 10 is provided with a reset spring 14, and the reset spring 14 is sleeved on the corresponding fixed support rod 13.

[0051] The back of the grinding equipment shell 1 is provided with a vacuum connection pump set 26, the vacuum connection pump set 26 is sealed and connected with a plurality of sealing connection pipes 25 on the side close to the grinding equipment shell 1, a plurality of gas discharge ports 27 are arranged on the vacuum connection pump set 26, the side of part of the vacuum adsorption suction head 7 away from the delay vacuum breaker 8 is fitted with the auxiliary blocking hollow plate 29, each ceramic piece 28 to be polished is movably arranged on the inside of the corresponding auxiliary blocking hollow plate 29, a flow guide groove 32 is arranged between every two modular connection tables 2, the gap between every two auxiliary blocking hollow plates 29 is above the corresponding fixed base 31, and the front of the grinding equipment shell 1 is provided with a grinding equipment control console 30.

[0052] In the specific implementation, the grinding device is arranged in the grinding device housing. After all the ceramic pieces 28 to be ground are adsorbed and fixed, the operator sends a starting and moving instruction to the grinding device through the grinding device console 30. The grinding device is driven by the corresponding driving mechanism to move from the initial position to the top of the first group of ceramic pieces 28 to be ground. During the movement, the grinding device console 30 controls the grinding head of the grinding device to make an initial height adjustment according to the preset thickness parameter of the ceramic pieces 28 to be ground, so that the distance between the grinding head and the upper surface of the ceramic pieces 28 to be ground reaches the preset initial grinding gap. Then, the grinding liquid spraying device on the grinding device is started to spray the grinding liquid. The grinding liquid is uniformly sprayed on the upper surface of the ceramic pieces 28 to be ground by the spraying nozzle. After the grinding liquid is uniformly distributed on the surface of the ceramic pieces 28 to be ground, the grinding device console 30 sends a grinding start instruction to the grinding device. The grinding head of the grinding device starts to grind the ceramic pieces 28 to be ground according to the preset grinding track.

[0053] During the grinding process, as the surface material of the ceramic pieces 28 to be ground is gradually removed, the thickness of the ceramic pieces 28 to be ground is continuously reduced. The grinding device console 30 sends an opening instruction to the electromagnetic vacuum breaker 18 according to the preset grinding time interval. After receiving the instruction, the electromagnetic driving mechanism inside the electromagnetic vacuum breaker 18 drives the vacuum breaker spool to move, opening the path to the atmosphere. At this time, the air inside the multifunctional connecting groove 5 enters the inside of the electromagnetic vacuum breaker 18 through the pressure balance hole 21 on the fixed connecting plate 20, and then enters the movable cavity formed by the sealing and restraining shell 15, the vacuum sealing plate 11 and the restraining bottom plate 16, thereby destroying the vacuum environment inside the movable cavity. The air pressure in the movable cavity gradually returns to normal pressure. The return spring 14 inside the lifting sleeve 10 is no longer subjected to the pulling force of the negative pressure, and starts to release the elastic potential energy, thereby pushing the lifting sleeve 10 to move to the side of the vacuum adsorption suction head 7. The movement of the lifting sleeve 10 drives the vacuum sealing plate 11 connected thereto to move synchronously. The vacuum sealing plate 11 drives the vacuum adsorption suction head 7 to move through the one-way sealing valve 9 and the delay vacuum breaker 8, and finally makes the ceramic pieces 28 to be ground on the vacuum adsorption suction head 7 move to the side of the grinding head of the grinding device, until the upper surface of the ceramic pieces 28 to be ground abuts against the grinding head, and the ceramic pieces 28 to be ground stop moving.

[0054] During the movement of the vacuum sealing plate 11, the multifunctional sensor 17 on the constraint bottom plate 16 monitors the position change of the vacuum sealing plate 11 in real time, and transmits the movement distance data to the grinding equipment console 30, which records the movement distance of the vacuum sealing plate 11, and then sends a re-evacuation instruction to the vacuum connection pump set 26, and the vacuum pump corresponding to the pipeline in the vacuum connection pump set 26 is started again to extract the air in the movable cavity, so that the movable cavity is re-formed into a vacuum state. Under the action of negative pressure, the vacuum sealing plate 11 drives the lifting sleeve 10 to overcome the elastic force of the reset spring 14, and moves to one side of the constraint bottom plate 16 until it returns to the initial adhering position, and the vacuum adsorption suction head 7 and the ceramic piece 28 to be ground are also reset.

[0055] After the vacuum adsorption suction head 7 is reset, the grinding equipment console 30 sends a height adjustment instruction to the grinding equipment according to the movement distance of the vacuum sealing plate 11 captured by the multifunctional sensor 17, controls the movement of the grinding head of the grinding equipment by an equal distance, and ensures that the grinding head and the upper surface of the ceramic piece 28 to be ground always maintain a predetermined grinding gap, so as to realize precise multi-section adjustment of the grinding position. The operator can repeat the above adjustment process according to the grinding precision requirement until the ceramic piece 28 to be ground reaches the preset thickness and surface precision.

[0056] The grinding liquid recovery tank at the bottom of the grinding equipment shell 1. During the grinding process, the grinding liquid sprayed on the surface of the ceramic piece 28 to be ground will spread around with the rotation of the grinding head. Since a flow guide groove 32 is arranged between every two modular connecting tables 2, and the gap between every two auxiliary blocking hollow plates 29 is above the corresponding fixed base 31, the excess grinding liquid will flow into the flow guide groove 32 along the outer side wall of the auxiliary blocking hollow plate 29. The flow guide groove 32 is inclined, and the grinding liquid flows along the flow guide groove 32 under the action of gravity and is finally collected into the grinding liquid recovery tank at the bottom of the grinding equipment shell 1, realizing the recycling of the grinding liquid and reducing resource waste and environmental pollution.

[0057] Since the auxiliary blocking hollow plate 29 has blocked the excess vacuum adsorption suction head 7 in the same group, and the ceramic piece 28 to be ground is closely adhered to the vacuum adsorption suction head 7, the grinding liquid is effectively prevented from entering the inside of the vacuum adsorption suction head 7, avoiding the blockage of the vacuum adsorption suction head 7 or the damage of the sealing performance of the vacuum system, and ensuring the stable operation of the equipment. When the first group of ceramic pieces 28 to be ground is ground, the grinding equipment console 30 first sends a stop grinding and displacement instruction to the grinding equipment, the grinding equipment stops the grinding action, and is driven by the driving mechanism to move above the next group of ceramic pieces 28 to be ground, preparing for the grinding of the next group of ceramic pieces.

[0058] The grinding equipment console 30 sends an opening instruction to the electromagnetic vacuum breaker 18 below the ceramic piece that has been polished, the vacuum breaker spool of the electromagnetic vacuum breaker 18 moves, external air enters the movable cavity, the vacuum state of the movable cavity is destroyed, under the action of the reset spring 14, the vacuum sealing plate 11 drives the lifting sleeve 10, the vacuum suction head 7 and the polished ceramic piece to move away from the constraint bottom plate 16, until the vacuum suction head 7 moves to a distance above the modular connection table 2, at this time the grinding equipment console 30 controls the electromagnetic vacuum breaker 18 to close.

[0059] Subsequently, the grinding equipment console 30 sends an opening instruction to the delay vacuum breaker 8, the vacuum breaker spool inside the delay vacuum breaker 8 moves after a delay, opening the passage of the vacuum suction head 7 to the outside, external air enters the inside of the vacuum suction head 7, destroying the vacuum state of the vacuum suction head 7, when the air pressure inside the vacuum suction head 7 returns to normal pressure, the polished ceramic piece is no longer adsorbed, and the operator can easily take it off the vacuum suction head 7.

[0060] After the operator takes off the polished ceramic piece, the surface of the modular connection table 2, the vacuum suction head 7 and the auxiliary blocking hollow plate 29 need to be cleaned, after cleaning, the operator puts the new ceramic piece to be polished 28 on the appropriate auxiliary blocking hollow plate 29, according to the previous placement and positioning method, places it on the group of vacuum suction heads 7, then the grinding equipment console 30 repeats the above vacuum adsorption and fixation process to adsorb and fix the new ceramic piece to be polished 28, and prepares for the next polishing.
