And secondly, the whole surface of the part to be ground of the ceramic ferrule is always in contact grinding with the grinding head, so that the processing progress of the V-shaped groove of the ceramic ferrule is consistent, one end of the V-shaped groove is not deep, the other end of the V-shaped groove is shallow, and the processing precision of the ceramic ferrule is effectively improved.

The grinding mechanism comprises a tool rest, the grinding head is arranged on the tool rest, and the grinding head and the tool rest are detachable. After long-term use, the grinding head inevitably also has abrasion, so that the cost for replacing the whole grinding mechanism is obviously too high, the grinding head and the tool rest are arranged to be detachable, and only the grinding head can be replaced after the grinding head is abraded, so that the use cost of the grinding head is reduced.

In some embodiments of the present application, the present application further includes an abrasive fluid supply assembly having an abrasive fluid disposed therein for providing an abrasive fluid to the ferrule. The grinding fluid supply assembly is positioned between the two grinding mechanisms.

In some embodiments of the present application, the clamp assembly includes two spaced clamps, and the power mechanism drives the clamp assembly to move back and forth between the two grinding mechanisms. The distance between the two clamps is equal to the distance between the grinding head and the grinding fluid supply assembly.

Specifically, when the power mechanism drives one of the fixtures to move to a position below the polishing head of the polishing mechanism, the other fixture is located below the polishing liquid supply assembly.

More specifically, when one of the clamps moves to the lower part of the grinding head, the grinding head starts to grind under the action of the power mechanism; and the other fixture is positioned below the slurry supply assembly, which supplies slurry to the ferrule in the other fixture.

This application will provide the lapping liquid, grind the twice process and go on simultaneously, can accelerate substantially the process velocity, improve machining efficiency.

In some embodiments of the present application, the feeding mechanism includes a conveying seat, the conveying seat includes two fixed conveying blocks and two movable conveying blocks, the conveying seat is provided with an outlet hole communicated with the material frame, and the outlet hole is located between the two fixed conveying blocks.

In some embodiments of the present application, the feeding mechanism includes material way and vibration dish, the vibration dish be connected with the material way, the material way pass through the transport seat and be connected with the anchor clamps subassembly.

Specifically, a large number of ceramic ferrules are arranged in a vibration disc, and the vibration disc works to arrange and convey the ceramic ferrules to a material channel.

In some embodiments of the present application, the detection mechanism includes a detection head, and the detection head is disposed at one end of the material channel.

In some embodiments of the present application, the two movable conveying blocks are a first conveying block and a second conveying block, respectively, the first conveying block is located between the two fixed conveying blocks, and the power mechanism drives the first conveying block to move.

Specifically, the first conveying block moves or exposes the leading-out hole, or shields the leading-out hole and connects the two fixed conveying blocks.

More specifically, if the leading-out hole is exposed, the two fixed conveying blocks are not communicated, and the ceramic ferrule cannot pass through the conveying seat, but falls into the leading-out hole under the action of gravity to lead in the material frame.

More specifically, the detection mechanism is connected with a power mechanism, and the power mechanism drives the second conveying block to move according to the detection result of the detection mechanism.

In some embodiments of the present application, the fixed delivery block interfaces with a clamp located below the slurry supply assembly.

If the first conveying block shields the leading-out hole and is connected with the two fixing blocks, the ceramic ferrule can smoothly pass through the conveying seat and reach the accommodating channel of the clamp below the grinding fluid supply assembly.

In some embodiments of the present application, the power mechanism drives the second conveying block to move, and the moving second conveying block connects the material channel and the fixed conveying block.

In some embodiments of the present application, a pushing assembly is disposed on one side of the conveying seat, and the pushing assembly pushes the ferrule on the second conveying block to move to the fixed conveying block. And the ceramic inserting core originally positioned on the fixed conveying block can be pushed into the accommodating channel of the clamp. And by analogy, the qualified ceramic ferrule is gradually guided into the accommodating channel of the clamp. And the unqualified ceramic core inserts are led out from the leading-out holes on the conveying seat.

In the present application, acceptable ferrules are individually introduced into a fixture below the slurry supply assembly. The ceramic inserting core is gradually pushed forwards, and the grinding fluid supply assembly only needs to lead out the grinding fluid from the clamp below at a preset position.

In some embodiments of the present application, the surfaces of the first conveying block, the second conveying block and the fixed conveying block are all provided with accommodating grooves for accommodating the ceramic inner core. Specifically, only one ceramic inner core can be accommodated in the accommodating groove.

In some embodiments of the present application, the receiving channel is a straight channel, and a longitudinal section of the receiving channel is adapted to a longitudinal section structure of the ferrule; the plurality of ceramic ferrules can be arranged in the accommodating channel along the length direction of the accommodating channel. Be different from the tradition and adopt the centre gripping subassembly to install fixedly to ceramic lock pin, this application adopts the holding passageway. Because the structure of the accommodating channel is matched with the ceramic ferrule, the moving direction of the ceramic ferrule is limited after the ceramic ferrule enters the accommodating channel, the ceramic ferrule can only move along the length direction of the accommodating channel, and can not displace in other directions, and then the ceramic ferrule is fixed in the accommodating channel by limiting the two ends of the accommodating channel.

And the accommodation channel can accommodate a plurality of ceramic lock pins, namely, the plurality of ceramic lock pins can be limited simultaneously. Compare in the pottery lock pin grinder on the market, the simple structure of this application, and the cost is lower.

In some embodiments of the present application, a notch is formed in the surface of the clamp, the notch is arranged along the length direction of the accommodating channel, and the notch is communicated with the accommodating channel. In this application, the width of notch is less than the width of ceramic lock pin, and the setting of notch does not influence the spacing of ceramic lock pin in anchor clamps promptly, and the ceramic lock pin is located the holding passageway all the time.

In the present application, the slurry introduction accommodating passage needs to pass through the notch. The grinding bit also needs to pass through the slot to act on the ferrule.

In the present application, for placing and grinding a plurality of ferrules, the following problems are present: the unground ferrule itself can experience dimensional molding errors during the molding process. When the plurality of ceramic ferrules are positioned in the accommodating channel, a certain height difference exists among the plurality of ceramic ferrules, and the surface of the ceramic ferrule to be processed is the top surface of the ceramic ferrule. Then it is inevitable that the polishing head will contact the higher height ferrule and will have a gap with the lower height ferrule after being moved downward. Then, after the grinding head uniformly grinds the ceramic ferrules, the depths of the V-shaped grooves on the different ceramic ferrules are different, and the machining precision is not high.

In view of the above, in some embodiments of the present application, a plurality of elastic members are installed in the jig, the elastic members corresponding to the ferrules in the receiving passages one-to-one, and the elastic members provide an upward force to the ferrules.

Specifically, the accommodating channel comprises a limiting surface, the limiting surface is the top surface of the accommodating channel, and the ceramic inner core positioned in the accommodating channel is in contact with the limiting surface. Of course, the force with which the ceramic core remains in contact with the stop surface comes from the resilient member. Therefore, the limiting surface in the accommodating channel is a reference surface for mounting the ceramic ferrule, and the processing precision of the whole ceramic ferrule can be ensured only by ensuring that the limiting surface is parallel to the bottom surface of the grinding head.

In some embodiments of the present application, the sidewall of the clamp has an inlet, and the inlet is communicated with the accommodating channel. The receiving channel may extend along a length direction thereof and may penetrate through the sidewall of the clip. In the present application, the ferrule is then pushed into the receiving channel from the entrance of the fixture.

The outlet is formed in the side wall of the clamp and communicated with the accommodating channel, and the inlet and the outlet are respectively located at two ends of the accommodating channel. The ferrule positioned within the receiving channel is directed out of the outlet.

Two separating stop blocks are arranged below the grinding mechanism, and when the clamp moves to the position below the grinding mechanism, the inlet and the outlet of the clamp are separated and stopped by the two separating stop blocks. The length that this application set up grinding channel can hold an integer number of ceramic inner core just, consequently after entry, export are separated and are kept off, ceramic inner core is fixed in the holding passageway.

And when the ceramic ferrule in the first clamp is ground at the first grinding mechanism, and the ceramic ferrule in the second clamp is guided into the first grinding mechanism, the power mechanism drives the clamp assembly to move, so that the second clamp is moved to the second grinding mechanism for grinding. While at the same time the first polishing mechanism is moved to a position below the slurry supply assembly, i.e., in abutment with the carrier. At this moment, the conveying seat can continuously convey the ceramic ferrule to be processed into the accommodating channel of the first fixture, and the ceramic ferrule to be processed can eject the ceramic ferrule which is originally positioned in the accommodating channel of the first fixture and is ground out of the outlet.

Therefore, the finished product frame is arranged below the grinding fluid supply assembly and corresponds to the outlet of the accommodating channel below the grinding fluid supply assembly.

This application only sets up the propelling movement subassembly of material loading to need not set up the power structure and the promotion structure of unloading. This application goes to promote ceramic inner core to get into the holding passageway through the propelling movement subassembly, also is ejecting by the ceramic inner core of propelling movement subassembly in with the holding passageway. The structure of the application is very simple, and the equipment cost is lower.

At this time, the following problems exist: when the ceramic ferrule is not placed in the accommodating channel, the elastic piece in the clamp is not blocked by the ceramic ferrule, and the elastic piece can be ejected upwards. The distance between the elastic element and the limiting surface of the accommodating channel is not enough to accommodate the elastic element.

In view of the above, in some embodiments of the present application, the resilient member includes a post and a spring, the spring is mounted below the post, and the post acts on the ferrule disposed in the receiving channel. Preferably, the top pillar is made of a material with a small friction coefficient.

The top column is provided with a guide surface. Specifically, the ceramic ferrule applies a thrust force to the guide surface of the ejection column, and the ceramic ferrule is driven to move downwards, so that a space for the ceramic ferrule to enter is reserved.

Specifically, the top surface edge of the top column is provided with a chamfer, and the chamfer forms the guide surface. In the above structure, the columnar structure provided with the chamfer is a structure which is easy to process. And the second jacking column is movable in the clamp, so that the jacking column is not limited in movement stroke, and the jacking column is prevented from displacing in the circumferential direction in the whole movement process. In the application, the chamfer is arranged on the top column and used as a guide surface, so that high reliability of stress guide can be ensured.

In some embodiments of the present application, the abrading head has a V-shaped configuration in longitudinal cross-section.

Detailed Description

The present application will now be described in detail with reference to the accompanying drawings.

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

The automatic grinding device for the ceramic ferrule 9, as shown in fig. 1, is an embodiment of the present application: the detection mechanism 10 is used for detecting whether the ceramic ferrule 9 is right side up or not; the feeding mechanism is connected with the detection mechanism 10 and is used for conveying the ceramic ferrule 9 to be ground to the accommodating channel 2 or the material frame; set up detection mechanism 10 and feed mechanism and be connected the cooperation for the material realizes detecting in the transportation, specifically detects ceramic lock pin 9 and whether openly up. The clamp 1 assembly is provided with an accommodating channel 2; the ceramic ferrules 9 can be arranged in the accommodating channel 2; a qualified ferrule 9 (i.e., the ferrule 9 with the face up) is transported to the receiving channel 2 of the fixture 1 assembly. And the material frame is used for storing the ceramic inserting core 9 to be ground.

The length of the grinding head 13 is adapted to the length of the accommodating channel 2. So that the grinding head 13 can press down on the surface of the ceramic inserting core 9 in the accommodating channel 2 to realize synchronous grinding. Preferably, the grinding head 13 has a length greater than the length of the accommodating channel 2. So that when the grinding head 13 reciprocates, the whole surface of the part to be ground of all the ceramic ferrules 9 is always ground by the grinding head 13.

Firstly, the ceramic inserting core 9 in the accommodating channel 2 is always stressed, so that the stability in the grinding process is better. Secondly, the whole surface of the part to be ground of the ceramic ferrule 9 is always in contact with the grinding head 13 for grinding, so that the processing progress of the V-shaped groove of the ceramic ferrule 9 is consistent, one end of the V-shaped groove is not deep, the other end of the V-shaped groove is not shallow, and the processing precision of the ceramic ferrule 9 is effectively improved.

The grinding mechanism 12 comprises a tool rest 14, the grinding head 13 is arranged on the tool rest 14, and the grinding head 13 and the tool rest 14 are detachable. After long-term use, the grinding head 13 inevitably wears, so that the cost for replacing the whole grinding mechanism 12 is obviously too high, the grinding head 13 and the tool rest 14 are arranged to be detachable, and only the grinding head 13 can be replaced after the grinding head 13 wears, so that the use cost of the application is reduced.

Based on the foregoing embodiment, as shown in fig. 2 and 3, another embodiment is provided, in which the present application further includes an abrasive liquid supply assembly 15, and the abrasive liquid supply assembly 15 is provided with an abrasive liquid therein for supplying the abrasive liquid to the ferrule 9. The slurry supply assembly 15 is located between the two polishing mechanisms 12.

The clamp 1 assembly comprises two clamps 1 with a distance, and the power mechanism drives the clamp 1 assembly to move back and forth between the two grinding mechanisms 12. The distance between the two fixtures 1 is equal to the distance between the polishing head 13 and the polishing liquid supply assembly 15.

Specifically, when the power mechanism drives one of the fixtures 1 to move below the polishing head 13 of the polishing mechanism 12, the other fixture 1 is located below the polishing liquid supply assembly 15.

More specifically, when one of the clamps 1 moves below the polishing head 13, the polishing head 13 starts to polish under the action of the power mechanism; while the other fixture 1 is located below the slurry supply assembly 15, the slurry supply assembly 15 supplies slurry to the ferrule 9 in the other fixture 1.

Based on the foregoing embodiment, as shown in fig. 4 and 5, another embodiment is provided, in which the feeding mechanism includes a conveying seat 24, the conveying seat 24 includes two fixed conveying blocks 25 and two movable conveying blocks, an outlet 23 communicating with the material frame is provided on the conveying seat 24, and the outlet 23 is located between the two fixed conveying blocks 25.

The feeding mechanism comprises a material channel 21 and a vibrating disk 22, the vibrating disk 22 is connected with the material channel 21, and the material channel 21 is connected with the clamp 1 assembly through a conveying seat 24. Specifically, a plurality of ferrules 9 are positioned within vibratory tray 22, and vibratory tray 22 operates to align and deliver ferrules 9 to throat 21. The detection mechanism 10 comprises a detection head 11, and the detection head 11 is arranged at one end of the material channel 21.

The two movable conveying blocks are respectively a first conveying block 26 and a second conveying block 27, the first conveying block 26 is positioned between the two fixed conveying blocks 25, and the power mechanism drives the first conveying block 26 to move. Specifically, the first conveying block 26 moves to expose the lead-out hole 23 or to shield the lead-out hole 23 and connect the two fixed conveying blocks 25.

More specifically, if the lead-out hole 23 is exposed, the two fixed delivery blocks 25 are not connected, and the ferrule 9 cannot pass through the delivery seat 24, but drops into the lead-out hole 23 by gravity to introduce the material frame. More specifically, the detecting mechanism 10 is connected to a power mechanism, and the power mechanism drives the second conveying block 27 to move according to the detection result of the detecting mechanism 10.

The fixed delivery block 25 is abutted with the jig 1 located below the slurry supply unit 15. If the first delivery block 26 blocks the outlet hole 23 and connects the two fixed blocks, the ferrule 9 can smoothly pass through the delivery seat 24 and reach the receiving passage 2 of the fixture 1 below the slurry supply module 15.

The power mechanism drives the second conveying block 27 to move, and the moving second conveying block 27 is connected with the material channel 21 and the fixed conveying block 25.

The pushing assembly 28 is arranged on one side of the conveying seat 24, and the pushing assembly 28 pushes the ceramic core insert 9 on the second conveying block 27 to move to the fixed conveying block 25. And the ferrule 9 originally positioned on the fixed conveying block 25 is pushed into the accommodating channel 2 of the fixture 1. And so on, the qualified ceramic ferrule 9 is gradually guided into the accommodating channel 2 of the fixture 1. While the failed ferrule 9 is led out from the lead-out hole 23 of the carrier seat 24.

In the present application, acceptable ferrules 9 are individually introduced into the fixture 1 below the slurry supply assembly 15. The ferrule 9 is gradually pushed forward, and the slurry supply unit 15 only needs to discharge the slurry to the lower jig 1 at a predetermined position.

In some embodiments of the present application, the surfaces of the first conveying block 26, the second conveying block 27 and the fixed conveying block 25 are all provided with accommodating grooves for accommodating ceramic cores. Specifically, only one ceramic inner core can be accommodated in the accommodating groove.

Based on the previous embodiment, as shown in fig. 6 to 8, another embodiment is provided, in which the accommodating channel 2 is a straight channel, and the longitudinal section of the accommodating channel 2 is adapted to the longitudinal section structure of the ferrule 9; a plurality of ferrules 9 may be arranged within the receiving channel 2 along the length of the receiving channel 2. Be different from the tradition and adopt the centre gripping subassembly to install fixedly to ceramic lock pin 9, this application adopts holding passageway 2. Because the structure of the accommodating channel 2 is adapted to the ferrule 9, the moving direction of the ferrule 9 is limited after entering the accommodating channel 2, specifically, the ferrule 9 can only move along the length direction of the accommodating channel 2 and can not displace in other directions, and then the fixing of the ferrule 9 in the accommodating channel 2 is realized by limiting the two ends of the accommodating channel 2.

And the receiving channel 2 can receive a plurality of ferrules 9, i.e. can simultaneously limit a plurality of ferrules 9. Compare in 9 grinder of ceramic lock pin on the market, the simple structure of this application, and the cost is lower.

Notch 3 has been seted up on anchor clamps 1 surface, notch 3 set up along the length direction of holding passageway 2, notch 3 and holding passageway 2 intercommunication. In the present application, the width of the notch 3 is smaller than the width of the ferrule 9, i.e., the setting of the notch 3 does not affect the position limitation of the ferrule 9 in the fixture 1, and the ferrule 9 is always located in the accommodating channel 2.

In the present application, the slurry introduction accommodating passage 2 needs to pass through the notch 3. Grinding bit 13 also needs to pass through slot 3 to act on ferrule 9.

In the present application, there are again the following problems with placing and grinding a plurality of ferrules 9: the as yet unground ferrule 9 itself can experience dimensional molding errors during the molding process. Then there will be a certain height difference between the ferrules 9 when the ferrules 9 are positioned in the receiving channel 2, and the surface of the ferrule 9 to be machined is the top surface thereof. It is inevitable that the grinding head 13 will come into contact with the higher-height ferrule 9 and will have a gap with the lower-height ferrule 9 after moving down. Then, after the polishing head 13 uniformly polishes the wafers, the depths of the V-grooves of the ferrules 9 are different, and the machining accuracy is not high.

In view of the above, in some embodiments of the present application, a plurality of elastic members are installed in the jig 1 in one-to-one correspondence with the ferrules 9 in the receiving passage 2, and the elastic members provide an upward force to the ferrules 9.

Specifically, the accommodating channel 2 comprises a limiting surface 4, the limiting surface 4 is a top surface of the accommodating channel 2, and the ceramic inner core located in the accommodating channel 2 is in contact with the limiting surface 4. Of course, the force with which the ceramic core remains in contact with the stop face 4 comes from the resilient member. Thus, the limiting surface 4 in the accommodating channel 2 is a reference surface for mounting the ferrule 9, and the machining precision of the entire ferrule 9 can be ensured only by ensuring that the limiting surface 4 is parallel to the bottom surface of the grinding head 13.

The side wall of the clamp 1 is provided with an inlet 51, and the inlet 51 is communicated with the accommodating channel 2. The receiving channel 2 may also be said to extend along the length direction thereof and penetrate through the side wall of the clamp 1. Then, in the present application, ferrule 9 enters receiving channel 2 and is pushed into receiving channel 2 from inlet 51 of fixture 1.

The side wall of the fixture 1 is provided with an outlet 52, the outlet 52 is communicated with the accommodating channel 2, and the inlet 51 and the outlet 52 are respectively located at two ends of the accommodating channel 2. Ferrule 9, which is located within receiving channel 2, is directed out of outlet 52.

Two separating blocks are arranged below the grinding mechanism 12, and when the clamp 1 moves to the position below the grinding mechanism 12, the inlet 51 and the outlet 52 of the clamp 1 are separated by the two separating blocks. The length of the grinding channel is set to be capable of containing an integral number of ceramic cores, so that the ceramic cores are fixed in the containing channel 2 after the inlet 51 and the outlet 52 are blocked.

When the ferrule 9 in the first fixture 1 is completely ground by the first grinding mechanism 12 and the ferrule 9 in the second fixture 1 is completely introduced, the power mechanism drives the fixture 1 assembly to move, so that the second fixture 1 moves to the second grinding mechanism 12 for grinding. While at the same time the first polishing mechanism 12 is moved to a position below the slurry supply assembly 15, i.e., in abutment with the carrier block 24. At this time, the delivery seat 24 continues to deliver the ferrule 9 to be processed into the receiving channel 2 of the first fixture 1, and the ferrule 9 to be processed ejects the polished ferrule 9, which is originally located in the receiving channel 2 of the first fixture 1, out of the outlet 52.

Therefore, the present application provides a finished frame under the slurry supply assembly 15, and the finished frame corresponds to the outlet 52 of the receiving channel 2 under the slurry supply assembly 15.

The feeding pushing assembly 28 is only arranged, and a power structure and a pushing structure of feeding are not needed. The ceramic inner core is pushed to enter the accommodating channel 2 through the pushing assembly 28, and the ceramic inner core in the accommodating channel 2 is also ejected out through the pushing assembly 28. The structure of the application is very simple, and the equipment cost is lower.

At this time, the following problems exist: when the ferrule 9 is not placed in the receiving channel 2, the elastic member located in the jig 1 is not blocked by the ferrule 9, and the elastic member is pushed upward. The distance between the elastic element and the limiting surface 4 of the accommodating channel 2 is not enough to accommodate the elastic element.

In view of the above, in some embodiments of the present application, the resilient member includes a post 6 and a spring 7, the spring 7 is mounted below the post 6, and the post 6 acts on the ferrule 9 positioned in the receiving channel 2. Preferably, the top pillar 6 is made of a material having a small friction coefficient.

The top column 6 is provided with a guide surface 8. Specifically, the ferrule 9 applies a pushing force to the guiding surface 8 of the top post 6, which drives the ferrule 9 to move downward, leaving a space for the ferrule 9 to enter.

Specifically, the top surface edge of the top column 6 is provided with a chamfer, and the chamfer forms the guide surface 8. In the above structure, the columnar structure provided with the chamfer is a structure which is easy to process. The second support pillar 6 is movable in the fixture 1, so the support pillar 6 does not have the limitation of the movement stroke, and the support pillar 6 is inevitably displaced in the circumferential direction in the whole movement process. In the application, the top post 6 is chamfered and the chamfered guide surface 8 is used, so that high reliability of force-receiving guidance can be ensured.

In the present application, the grinding head 13 has a V-shaped longitudinal section.

The present application has been described in detail above, and specific examples thereof are used herein to explain the principles and implementations of the present application, which are presented solely to aid in understanding the present application and its core concepts. It should be noted that, for those skilled in the art, it is possible to make several improvements and modifications to the present application without departing from the principle of the present application, and such improvements and modifications also fall within the scope of the claims of the present application.
