Next, the metal ring feeding apparatus will be specifically described by taking an example of feeding a metal ring to be polished.

Referring to fig. 1 and fig. 2, in the present embodiment, a metal ring 100 to be polished includes a first ring segment 101 and a second ring segment 102 having an outer diameter larger than that of the first ring segment 101, and an outer circumferential surface of the first ring segment 101 is a surface to be polished. In order to be suitable for directly grinding the metal ring 100 after the loading is completed, in the embodiment, the metal ring 100 may be directly loaded by the disc-shaped carrier plate 1 suitable for the flat grinder.

Specifically, the carrier tray 1 includes a circular carrier tray body 11, a plurality of bushes 12, and a plurality of pins 200. The outer edge of the carrier plate body 11 is provided with gear teeth 111 to make the carrier plate body 11 driven by the flat grinding machine to rotate, and the carrier plate body 11 is provided with a plurality of first counter bores 112. The plurality of bushings 12 are disposed in the plurality of first counter-sunk holes 112 in a one-to-one correspondence manner, each bushing 12 has a second counter-sunk hole 121, the second counter-sunk hole 121 includes a first hole section and a second hole section having a smaller diameter than the first hole section, and the diameter of the first hole section is between the outer diameter of the first ring section 101 and the outer diameter of the second ring section 102, so that the first ring section 101 of the metal ring 100 can be inserted into the first hole section, and the second ring section 102 of the metal ring 100 is located outside the bushing 12. A plurality of pins 200 can be inserted through the metal ring 100 and into the second hole segments of the respective bushings 12 one by one to press the metal ring 100 against the bushings 12.

By means of the structure, the bearing disc body 11 is provided with the bush 12 and the pin 200 to position the metal ring 100, so that the metal ring 100 can be kept in a stable posture abutting against the bush 12 under the gravity pressure of the pin 200, the metal ring 100 is ensured not to fall off, and the structure can also ensure that all the metal rings 100 on the bearing disc 1 can have the same and accurate placing posture and height position when being ground by a flat grinding machine, namely, the grinding process of each metal ring 100 is ensured to be uniform, and the integral grinding effect of all the metal rings 100 is ensured. Meanwhile, the movable pin 200 is pressed against the metal ring 100, so that the metal ring 100 can be conveniently placed and taken out, and the operation efficiency is high.

In this embodiment, the axial length of the first hole segment is preferably smaller than the axial length of the first ring segment 101, so that when the metal ring 100 is pressed against the liner 12, a gap is formed between the second ring segment 102 of the metal ring 100 and the liner 12, and thus, during the grinding operation, a portion of the second ring segment 102 close to a transition step surface between the second ring segment 102 and the first ring segment 101 can contact with a grinding component of the flat grinding machine, thereby avoiding grinding dead corners.

It will be appreciated that in this embodiment, the extent of the profile of the pin 200 for pressing against the head of the metal ring 100 is preferably within the profile of the outer edge of the second ring segment 102, thereby ensuring that all parts of the outer peripheral surface of the second ring segment 102 are able to come into contact with the grinding components of the flat grinding machine.

In this embodiment, the bushing 12 may be riveted to the carrier tray body 11. Compared with welding connection, the riveting connection mode can facilitate forming hard mechanical limit through the appearance structure of the bushing 12 and the first counter sink 112, ensure that the connection position of each bushing 12 is not influenced by factors such as welding position accuracy and heating deformation degree, and is more suitable for ejecting the bushing 12 out of the bearing disc body 11 in a non-destructive mode when the bushing 12 is worn and the bushing 12 which is adaptive to different metal rings 100 needs to be replaced. In contrast to a threaded connection, the riveted connection has an alternative, reliable connection, which prevents the bushing 12 from loosening during the grinding operation.

In this embodiment, the hardness of the bushing 12 and the pin 200 is less than that of the metal ring 100, so that the bushing 12 and the pin 200 will not scratch the metal ring 100 during the assembly of the three and the pressing contact process after the assembly.

Referring to fig. 1, in the embodiment, the first counter sink holes 112 are distributed in the carrier tray body 11 in an array, and each of the first counter sink holes 112 is preferably distributed symmetrically with respect to a center point of the carrier tray body 11, or with respect to a diameter of the carrier tray body 11, so that all the metal rings 100 on the carrier tray are stressed uniformly during the polishing operation, and the polishing effect is consistent.

In order to improve the efficiency of loading and unloading operations for loading and unloading the metal rings 100 and the pins 200 into or from the carrier tray body 11, a mechanical arm or other equipment may be used, and the number of the metal rings 100 or the pins 200 picked up by the mechanical equipment each time is a certain integer M, for this reason, in this embodiment, the number of the first countersunk holes 112 in any row or any column on the carrier tray body 11 is an integral multiple of the same integer M, so that in the loading and unloading operations of the mechanical equipment, the above structural arrangement of the carrier tray body 11 may be beneficial to simplifying the difficulty of programming operations, and is suitable for completing the loading and unloading operations for the metal rings 100 and the pins 200 in all hole sites in the carrier tray through certain carrying times.

Since the metal ring 100 is ground using a flat grinder, in order to avoid contact wear with the grinding parts of the flat grinder, the end surface of the liner 12 is preferably located inside the surface of the carrier disc body 11, i.e., the end surface of the liner 12 is flush with the surface of the carrier disc body 11 or below the surface of the carrier disc body 11. Preferably, in the present embodiment, the end surface of the bushing 12 is flush with the surface of the carrier plate body 11, so that no step surface is formed between the end surface of the bushing 12 and the surface of the carrier plate body 11, thereby avoiding accumulation of grinding media, residue, and the like.

Referring to fig. 2, the length of the pin 200 is set such that, after the pin is inserted into the bushing 12, one end of the pin inserted into the bushing 12 is located in the second hole section or the first counter sink 112, that is, does not extend out of the bottom of the carrier tray body 11, so that, during the transportation process of the carrier tray 1, even though an external transportation device or a load passes through the bottom of the carrier tray body 11 as a bearing surface, the pin 200 is not abutted, thereby ensuring that the fixed metal ring 100 of the carrier tray 1 is stably placed in the operation links such as transportation, storage, and the like.

Referring to fig. 2, in order to facilitate the insertion of the pin 200 into the bushing 12, a guiding portion 201 may be disposed at one end of the pin 200 inserted into the bushing 12, and the guiding portion 201 may be in the shape of a protruding ball or a frustum, so as to avoid the dimensional deviation of the pin 200 and the bushing 12, and the influence of the positioning deviation on the assembling accuracy and the assembling accuracy when an automatic device is used for automatic assembling.

Referring to fig. 1, the bearing tray body 11 is provided with a positioning hole 113, and the positioning hole 113 may be conveniently connected to and positioned on a flat grinder platform, or the positioning hole 113 may be matched with a first positioning pin disposed on an external structure such as a transfer device and a storage rack for transferring and storing the bearing tray 1, so as to maintain the bearing tray 1 in an accurate posture.

Further, for the convenience of mechanical or manual judgment whether the placing posture of the bearing disc 1 is accurate, the bearing disc body 11 can be further provided with a fool-proof structure, the fool-proof structure can be a fool-proof hole 114 which is different from the positioning hole 113 structure and is arranged on the bearing disc body 11 and is shown in fig. 1, and the bearing disc 1 can be prevented from being misplaced by inserting structures such as a fool-proof pin which can be matched and connected with the fool-proof hole 114 in an inserting mode through the arrangement of an external structure.

Referring to fig. 3 to 9, in order to supply the empty carrier tray 1, automatically insert the empty carrier plate 321 into the metal ring 100, and collect the full carrier plate 321 for use, the feeding apparatus for metal ring 100 further includes a pair of buffer devices 2, a transferring device 3 disposed between the pair of buffer devices 2, and a feeding device 4 besides the carrier tray 1, wherein the carrier tray 1 has a cavity (i.e., a first countersunk hole 112) for placing the metal ring 100. The transfer device 3 can be translated back and forth to be respectively butted against the pair of buffer devices 2. The pair of buffer devices 2 are respectively configured to supply the carrier tray 1 to the transfer device 3 and receive the carrier tray 1 supplied from the transfer device 3. The loading device 4 is configured to load the metal rings 100 into the pockets of the carrier tray 1 carried on the transfer device 3.

By the above structure, the two buffer devices 2 are respectively used for bearing an empty bearing plate 321 and a full bearing plate 1, during operation, the transferring device 3 is firstly translated to be in butt joint with one buffer device 2, the buffer device 2 places the empty bearing plate 321 and the transferring device 3, then the feeding device 4 can load the metal ring 100 into the bearing cavity of the bearing plate 1, after the bearing plate 1 is fully loaded, the transferring device 3 is translated to be in butt joint with the other buffer device 2, and the buffer device 2 receives the full bearing plate 1 for use.

It should be noted that, in the operation of the metal ring 100 loading device, the loading device 4 may be configured to only load the metal ring 100 into the carrier plate 1, and then manually put the pins 200 into the carrier plate 1 to press and hold the metal ring 100. In the present embodiment, the loading device 4 preferably places the metal ring 100 in each cavity of the carrier tray 1, and then places the pin 200 in each cavity to further improve the efficiency of the operation, and the details of the loading structure will be described later.

Referring to fig. 3 to fig. 5, in the present embodiment, a pair of buffer devices 2 may be symmetrically disposed on both sides of the upstream and downstream of the transfer device 3, and each buffer device 2 includes a frame 21 and a lifting mechanism 22. The frame body 21 comprises a pair of oppositely arranged wall plates 211, a plurality of carrying plates 212 are arranged on the opposite side walls of the pair of wall plates 211 along the vertical direction, the carrying plates 212 on the pair of wall plates 211 are arranged in a one-to-one correspondence and at the same height so as to form a carrying part for carrying cached carrier trays 1 in a matching manner, and the distance between any pair of vertically adjacent wall plates 211 is larger than the thickness of the carrier trays 1. The lifting mechanism 22 is configured to lift the frame 21.

The transfer device 3 moves in and out of the two frames 21 located on both sides thereof, and specifically, extends between the two mounting plates 212, so that when the frame 21 is lowered by the elevating mechanism 22 of the buffer device 2 located upstream of the transfer device 3, the carrier tray 1 is supplied to the mounting plate 212, and when the frame 21 is lifted by the elevating mechanism 22 of the buffer device 2 located downstream of the transfer device 3, the carrier tray 1 mounted on the mounting plate 212 is received.

Taking the output carrier tray 1 as an example, the conventional buffer device 2 is complicated to collect and output the carrier trays 1, and the conventional buffer device 2 is to stack the entire stack of carrier trays 1 for standby, and when one carrier tray 1 needs to be output, the entire stack of carrier trays 1 is placed together on an external receiving structure (such as a conveyor belt or a transplanting mechanism in this embodiment), and then all the carrier trays 1 except the lowermost carrier tray 1 are lifted. The buffer device 2 provided by this embodiment is configured with a plurality of placing plates 212, so that the carrying tray 1 carried by the buffer device is placed at intervals up and down, and the carrying tray 1 placed on one pair of placing plates 212 can be placed on the carrying device by the lifting action of the lifting mechanism 22, thereby completing the output operation of the carrying tray 1, and greatly reducing the cycle time of a single operation. The action process of the buffer device 2 collecting the carrier tray 1 output by the carrier device is generally opposite to the above-mentioned output operation process, and is not described herein again.

Referring to fig. 5, in the present embodiment, the set plate 212 is provided with a first positioning pin 213 extending along the vertical direction, and the carrier tray 1 is provided with a positioning hole 113 capable of being inserted into the first positioning pin 213 when the carrier tray is correctly mounted on the set plate 212. The first positioning pin 213 is inserted and matched with the positioning hole 113 for positioning, so that the bearing tray 1 output or collected by the buffer device 2 can have an accurate and determined posture, and is suitable for coordinate matching of subsequent automatic operation.

Alternatively, in other embodiments, the positioning hole 113 may be disposed on the placing plate 212, and the protruding first positioning pin 213 may be disposed on the carrier tray 1, which is not limited herein.

In order to facilitate quick loading of the carrier tray 1, the first positioning pins 213 provided on the pair of mounting plates 212 forming the loading portion are symmetrically positioned. The fool-proof pin 214 can be further arranged on one of the pair of placing plates 212 which form the placing part, the fool-proof hole 114 which can be inserted with the fool-proof pin 214 when the bearing plate 1 is correctly placed on the placing plate 212 is arranged on the bearing plate 1, the purpose is that when the bearing plate 1 needs to be placed in the buffer device 2 in a unique determined posture, and the bearing plate 1 is in a symmetrical mechanism, the fool-proof structure can avoid the situation of placing posture error caused by manual judgment error.

Because the positioning hole 113 has an accurate mechanical positioning effect, the aperture of the fool-proof hole 114 can be set to be larger than the outer diameter of the fool-proof pin 214, so as to reduce the difficulty in manually placing the carrier tray 1 into the buffer device 2.

In order to obtain the same fool-proof effect, in other alternative embodiments, the first positioning pins 213 provided on the pair of placing plates 212 that cooperate to form the placing portion are staggered in position so that the carrier tray 1 can be placed on the buffer device 2 only in a uniquely determined posture.

In this embodiment, two ends of the placing plate 212 are provided with the limiting blocks 215 for limiting the placing positions of the bearing disc 1, specifically, as shown in fig. 5, one side of the two limiting blocks 215 opposite to each other has an arc shape adapted to the shape of the bearing disc 1, so that the purpose of guiding the bearing disc 1 is achieved when the bearing disc 1 is placed manually, and the difficulty of manual operation is reduced.

In order to know information about whether the buffer device 2 is empty or full, the elevating mechanism 22 is provided with a detecting element 23 for detecting the housing 21. Specifically, the detecting member 23 is provided at least at the lowest elevation position, the highest elevation position, and an intermediate elevation position between the lowest elevation position and the highest elevation position of the frame body 21. Taking the buffer device 2 located at the upstream end of the transfer device 3 as an example, when the buffer device 2 is fully loaded, the frame 21 is located at the highest elevation position to place each carrier tray 1 on the transfer device 3 in a descending manner, and when the buffer device 2 is located at the lowest elevation position, that is, when the carrier tray 1 loaded thereon is completely discharged, the detection element 23 is provided at the intermediate elevation position between the lowest elevation position and the highest elevation position, so that the operator can be reminded to prepare for replenishing the carrier tray 1 before the buffer device 2 is empty.

As shown in fig. 5, the detecting element 23 may optionally include a slot-type photoelectric switch 231 disposed at the fixed end of the lifting mechanism 22, and a blocking piece 232 disposed at the movable end of the lifting mechanism 22, wherein the blocking piece 232 can move into and out of the detecting slot of the slot-type photoelectric switch 231 along the vertical direction.

As shown in fig. 5, in this embodiment, the lifting mechanism 22 may include a screw module driven by a servo motor, the screw module is vertically disposed, and the movable end of the screw module is fixedly connected to the frame 21. In order to reduce the load of the lifting mechanism 22, the wall plate 211 of the frame 21 may be provided with a hollow lightening hole.

Moreover, the carrier tray 1 positioned by the first positioning portion 322 can have an accurate spatial position, and is suitable for accurately transferring the carrier tray 1 to each station, thereby facilitating the accurate feeding operation of the metal ring 100.

In order to enable each station to operate uninterruptedly, the transfer device 3 provided in this embodiment further includes a jacking mechanism 33, where the jacking mechanism 33 is provided with N-1 (i.e., 2), each jacking mechanism 33 corresponds to N-1 (i.e., 2) processing stations one by one, and the jacking mechanism 33 is configured to jack up or lower the carrier tray 1 located at each processing station.

As shown in fig. 6, the jacking mechanism 33 can jack up the carrier tray mechanism 32 from the carrier tray 1 carried by the previous station, so that the carrier tray 1 is separated from the carrier tray mechanism 32 to perform the loading operation of the metal ring 100 or the pin 200, and in this process, the carrier tray mechanism 32 can be reset to the loading station to receive the empty carrier tray 1, thereby realizing the synchronous operation of the receiving, shifting and outputting operations of the carrier tray 1.
