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.

[0022] The present application will be further described below in connection with the embodiments.

[0023] Embodiment: 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.

[0024] A plurality of movable connection grooves 3 are formed on the inner side of the modular connection table 2, and each vacuum suction head 7 is movably arranged in the corresponding movable connection groove 3. A plurality of lifting control grooves 4 are formed on 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 plurality of multifunctional connection grooves 5 are formed on the inner side of the grinding equipment shell 1, and the multifunctional connection grooves 5 are in communication with the plurality of lifting control grooves 4. A sealing constraint shell 15 is arranged on 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 on 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.

[0025] A multifunctional sensor 17 is embedded on 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.

[0026] 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 on 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 on the inner side of the multifunctional connection groove 5, and each sealing connection head 22 is connected to the corresponding fixed connection plate 20 at one end.

[0027] In a specific implementation, the operator sends a start command to the vacuum connection pump unit 26 through the grinding equipment console 30. After receiving the command, the vacuum connection pump unit 26 starts synchronously, and begins to extract air in the system. At this time, the air flows along the preset air flow path under the negative pressure of the vacuum pump, first enters the adsorption end of the vacuum adsorption suction head 7, then passes through the delay vacuum breaker 8 connected sealingly below the vacuum adsorption suction head 7, the first one-way sealing valve 9 connected sealingly below the delay vacuum breaker 8, the lifting sleeve 10 connected sealingly below the first one-way sealing valve 9, then enters the sealing constraint shell 15 inside the lifting control groove 4, and then passes through the electromagnetic vacuum breaker 18 connected sealingly on the constraint bottom plate 16, the second one-way sealing valve 19 on the side of the electromagnetic vacuum breaker 18, and then enters the multifunctional connection groove 5 through the pressure balance hole 21 on the fixed connection plate 20. After being collected by the sealing connection head 22 inside the multifunctional connection groove 5, the air is transported to the dispersion connection pipe 23, and the dispersion connection pipe 23 divides the air into multiple air extraction connection pipes 24. The air enters the vacuum connection pump unit 26 through the sealing connection pipe 25 connected vertically by the air extraction connection pipe 24, and finally is discharged outside the equipment through the multiple gas discharge ports 27 on the vacuum connection pump unit 26.

[0028] Due to the differences in size specifications of the ceramic pieces 28 to be polished, and the array distribution of the vacuum adsorption suction heads 7 inside the modular connection table 2, if the ceramic pieces 28 to be polished are directly placed on the modular connection table 2, it may not be possible to completely cover some of the vacuum adsorption suction heads 7, which may cause the grinding liquid to enter the interior of the vacuum adsorption suction heads 7 that are not covered during the subsequent grinding process, affecting the sealing performance of the vacuum system and the service life of the equipment. Therefore, before placing the ceramic pieces 28 to be polished, an auxiliary blocking hollow plate 29 is selected according to the actual size of the ceramic pieces 28 to be polished. The inner profile of the auxiliary blocking hollow plate 29 matches the outer shape of the ceramic pieces 28 to be polished, and the outer size can cover all the vacuum adsorption suction heads 7 that may be involved in adsorption in the same group. The operator puts the auxiliary blocking hollow plate 29 on the outside of the ceramic pieces 28 to be polished, so that the lower surface of the auxiliary blocking hollow plate 29 is in contact with the vacuum adsorption suction heads 7 on the modular connection table 2, thereby blocking the excess vacuum adsorption suction heads 7 in the same group, ensuring that only the vacuum adsorption suction heads 7 involved in adsorption play a role in the subsequent vacuum adsorption process, and preventing the grinding liquid from entering the unused vacuum adsorption suction heads 7.

[0029] After the installation of the auxiliary barrier hollow plate 29 is completed, the operator places the to-be-ground ceramic sheet 28 sleeved with the auxiliary barrier hollow plate 29 above the modular connection table 2, so that the to-be-ground ceramic sheet 28 covers the preset group of vacuum suction heads 7 together with the auxiliary barrier hollow plate 29, at this time, the worker needs to ensure that the center of the to-be-ground ceramic sheet 28 is aligned with the group of vacuum suction heads 7, so as to avoid uneven force on the ceramic sheet in the subsequent grinding process due to initial positioning deviation, affecting the grinding precision. After the worker sends a signal that the to-be-ground ceramic sheet 28 is placed, the grinding equipment console 30 sends a vacuum pumping instruction to the group of suction unit pipelines to the vacuum connection pump set 26, the vacuum pump corresponding to the pipeline in the vacuum connection pump set 26 increases the pumping intensity, and starts to pump the inside of the vacuum suction head 7. With the air being continuously pumped out, the air pressure between the vacuum suction head 7 and the to-be-ground ceramic sheet 28 gradually decreases, forming a negative pressure. When the negative pressure reaches the preset suction pressure threshold, the to-be-ground ceramic sheet 28 and the auxiliary barrier hollow plate 29 are firmly adsorbed on the group of vacuum suction heads 7 under the action of atmospheric pressure, and the preliminary adsorption and fixation is completed.

[0030] Please refer to Figure 3 Figure 8 The present application provides a technical solution: a one-way sealing valve 9 is sealingly connected below the delay vacuum breaker 8, the one-way sealing valve 9 is used to block the flow of gas to the inside of the vacuum suction head 7 and the delay vacuum breaker 8 in a vacuum state, a dispersion connecting pipe 23 is arranged in the multifunctional connecting groove 5, the other ends of a plurality of sealing connecting heads 22 are fixedly connected with the dispersion connecting pipe 23, the dispersion connecting pipe 23 is in communication with the inner walls of the plurality of sealing connecting heads 22, and a plurality of pipeline connecting grooves 6 are arranged at the back of the grinding equipment shell 1.

[0031] The multifunctional connecting groove 5 is provided with a dispersion connecting pipe 23, the other ends of a plurality of sealing connecting heads 22 are fixedly connected with the dispersion connecting pipe 23, the dispersion connecting pipe 23 is in communication with the inner walls of the plurality of sealing connecting heads 22, a plurality of pipeline connecting grooves 6 are arranged at 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, and each sealing connecting pipe 25 is fixedly connected with a corresponding air pumping connecting pipe 24 in a vertical center, and the sealing connecting pipe 25 is in communication with the inner wall of the air pumping connecting pipe 24.

[0032] ​In the specific implementation, during the vacuumizing process, the air inside the delay vacuum breaker 8 and the 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 inside the movable cavity is gradually extracted to make the air pressure gradually decrease, since the vacuum sealing plate 11 is completely attached to the inner wall of the sealing constraint shell 15, and the vacuum sealing plate 11 is connected with the lifting sleeve 10 on one side, under the action of the negative pressure in the movable cavity, the vacuum sealing plate 11 will drive the lifting sleeve 10 connected therewith to overcome the elastic force of the return spring 14 inside the lifting sleeve 10, and slowly move to the 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 it to the grinding equipment console 30, after receiving the signal, the grinding equipment console 30 judges that the stable vacuum state in the movable cavity has been reached, and the position of the vacuum adsorption suction head 7 has been adjusted to the right position, and then sends a command to stop the 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.

[0033] Due to the existence of the one-way sealing valve 9 and the two-way sealing valve 19, the 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 attachment state of the vacuum sealing plate 11 and the constraint bottom plate 16, at the same time, the lifting sleeve 10 connected with the vacuum sealing plate 11 also remains at the current position, at the same time, the vacuum adsorption suction head 7 will move together with the lifting sleeve 10, finally making the top end of the vacuum adsorption suction head 7 keep parallel with the top end of the modular connection table 2, and the lower surface of the auxiliary blocking hollow plate 29 also attaches to the top end of the modular connection table 2, completing the final adsorption and fixation of the ceramic sheet 28 to be polished, the operator will lay the remaining ceramic sheets 28 to be polished on the other groups of vacuum adsorption suction heads on the modular connection table 2 according to the above process, and complete the adsorption and fixation of all the ceramic sheets 28 to be polished.

[0034] Please refer to Figure 2 - Figure 8The application provides a technical scheme: a lifting sleeve 10 is sealingly connected below a one-way sealing valve 9, a reset spring 14 is arranged on the inner side of the lifting sleeve 10, and the lifting sleeve 10 is driven to move to the side of the vacuum adsorption suction head 7 by the reset spring 14 after the vacuum state of the lifting sleeve 10 is broken, one side of the lifting sleeve 10 close to the multifunctional connecting groove 5 is connected with a vacuum sealing plate 11, a fixed supporting block 12 is arranged on the inner side of the lifting sleeve 10, a fixed supporting rod 13 is arranged at the center of the lifting sleeve 10, one end of the fixed supporting rod 13 is connected with the fixed supporting block 12, and the reset spring 14 is sleeved on the corresponding fixed supporting rod 13.

[0035] The back of the grinding equipment shell 1 is provided with a vacuum connection pump unit 26, the vacuum connection pump unit 26 is sealingly connected with a plurality of sealing connection pipes 25 on one side close to the grinding equipment shell 1, a plurality of gas discharge ports 27 are arranged on the vacuum connection pump unit 26, one side of part of the vacuum adsorption suction heads 7 away from the time-delay vacuum breaker 8 is attached to an auxiliary blocking hollow plate 29, each to-be-ground ceramic sheet 28 is movably arranged on the inner side of the corresponding auxiliary blocking hollow plate 29, 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, and the front of the grinding equipment shell 1 is provided with a grinding equipment control console 30.

[0036] In the embodiment, the grinding equipment shell is provided with a grinding equipment, after all the to-be-ground ceramic sheets 28 are adsorbed and fixed, an operator sends a starting and moving instruction to the grinding equipment through the grinding equipment control console 30, the grinding equipment is driven by the corresponding driving mechanism and moves from an initial position to above the first group of to-be-ground ceramic sheets 28, in the moving process, the grinding equipment control console 30 controls the grinding head of the grinding equipment to make initial height adjustment according to the preset thickness parameter of the to-be-ground ceramic sheet 28, so that the distance between the grinding head and the upper surface of the to-be-ground ceramic sheet 28 reaches the preset initial grinding gap, then the grinding liquid spraying equipment on the grinding equipment is started to spray the grinding liquid, the grinding liquid is uniformly sprayed on the upper surface of the to-be-ground ceramic sheet 28 through the spraying nozzle, after the grinding liquid is uniformly distributed on the surface of the to-be-ground ceramic sheet 28, the grinding equipment control console 30 sends a grinding starting instruction to the grinding equipment, and the grinding head of the grinding equipment starts to grind the to-be-ground ceramic sheet 28 according to the preset grinding track.

[0037] In the grinding process, as the surface material of the ceramic sheet 28 to be ground is gradually removed, its thickness is continuously reduced. The grinding equipment 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 drive mechanism inside the electromagnetic vacuum breaker 18 drives the vacuum breaker valve core 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 vacuum sealing plate 11 and the constraint bottom plate 16 inside the sealed constraint shell 15, destroying the vacuum environment inside the movable cavity. The air pressure in the movable cavity gradually returns to normal pressure. The reset spring 14 inside the lifting sleeve 10 is no longer subjected to the pulling force of the negative pressure, and begins to release the elastic potential energy, pushing the lifting sleeve 10 to move to the side of the vacuum suction chuck 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 suction chuck 7 to move through the one-way sealing valve 9 and the delay vacuum breaker 8, and finally moves the ceramic sheet 28 to be ground on the vacuum suction chuck 7 to the side of the grinding head of the grinding equipment, until the upper surface of the ceramic sheet 28 to be ground abuts against the grinding head, and the ceramic sheet 28 to be ground stops moving.

[0038] 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. The grinding equipment console 30 records the movement distance of the vacuum sealing plate 11, and then sends a re-evacuation instruction to the vacuum connection pump set 26. 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 re-forms a vacuum state. Under the action of negative pressure, the vacuum sealing plate 11 drives the lifting sleeve 10 to move to the side of the constraint bottom plate 16 against the elastic force of the reset spring 14, until it returns to the initial abutting position. The vacuum suction chuck 7 and the ceramic sheet 28 to be ground also reset.

[0039] After the vacuum suction chuck 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 grinding head of the grinding equipment to move a distance equal to the distance, and ensures that the grinding head and the upper surface of the ceramic sheet 28 to be ground always maintain a preset 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 sheet 28 to be ground reaches the preset thickness and surface precision.

[0040] The grinding liquid recovery tank is arranged at the bottom of the grinding equipment shell 1. During the grinding process, the grinding liquid sprayed on the surface of the ceramic sheet 28 to be ground will spread around with the rotation of the grinding head. Since the 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 located directly above the corresponding fixed base 31, the excessive 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 arranged in an inclined manner, 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, so that the grinding liquid can be recycled, and resource waste and environmental pollution can be reduced.

[0041] Since the auxiliary blocking hollow plate 29 has blocked the excessive vacuum suction heads 7 in the same group, and the ceramic sheet 28 to be ground is closely attached to the vacuum suction head 7, the grinding liquid is effectively prevented from entering the inside of the vacuum suction head 7, so that the vacuum suction head 7 is prevented from being blocked or the sealing property of the vacuum system is prevented from being damaged, and the stable operation of the equipment is ensured. When the first group of ceramic sheets 28 to be ground are ground, the grinding equipment control console 30 first sends a stop grinding and displacement instruction to the grinding equipment, the grinding equipment stops the grinding action, and is moved to the upper side of the next group of ceramic sheets 28 to be ground under the driving of the driving mechanism, so as to prepare for the grinding of the next group of ceramic sheets.

[0042] The grinding equipment control console 30 sends an opening instruction to the electromagnetic vacuum breaker 18 below the ceramic sheet that has been ground. The vacuum breaker spool of the electromagnetic vacuum breaker 18 moves, external air enters the movable cavity, and 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 ground ceramic sheet to move away from the constraint bottom plate 16, until the vacuum suction head 7 moves to a distance above the modular connecting table 2. At this time, the grinding equipment control console 30 controls the electromagnetic vacuum breaker 18 to be closed.

[0043] Subsequently, the grinding equipment control 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, opens the path between the vacuum suction head 7 and the outside, external air enters the inside of the vacuum suction head 7, and the vacuum state of the vacuum suction head 7 is destroyed. When the air pressure in the vacuum suction head 7 returns to normal pressure, the ground ceramic sheet is no longer adsorbed, and the operator can easily take it off from the vacuum suction head 7.

[0044] After the ceramic piece is polished, the operator needs to clean the surface of the modular connecting table 2, the vacuum adsorption suction head 7 and the auxiliary barrier hollow plate 29. After cleaning, the operator puts the new ceramic piece to be polished 28 on the appropriate auxiliary barrier hollow plate 29, and places it on the vacuum adsorption suction head 7 according to the previous placement and positioning method.
