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, each bushing 12 has a second counter-sunk hole 121, and the second counter-sunk holes 121 form a bearing cavity capable of placing the metal ring 100 and the pin 200, specifically, the second counter-sunk hole 121 includes a first hole section and a second hole section having a diameter smaller than that of 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.

It can be understood that, in order to remove the metal ring 100, the pin 200 pressing the metal ring 100 is removed from the carrier tray 1, and for this reason, the metal ring blanking apparatus provided in this embodiment can also replace the manual removal of the pin 200 inserted in the carrier tray 1.

Referring to fig. 3, the metal ring blanking apparatus includes a pair of buffer devices 2, a transfer device 3 disposed between the pair of buffer devices 2, a pin blanking device, and a metal ring blanking device 5. The transfer device 3 can be translated back and forth to be respectively butted with a pair of buffer devices 2 at two ends thereof. The pair of buffer devices 2 are configured to supply the transfer device 3 with the loaded carrier tray 1 loaded with the metal rings 100 and the pins 200, and to receive the empty carrier tray 1 supplied from the transfer device 3; the pin blanking device is configured to move out the pins 200 inserted in the carrier tray 1; a metal ring blanking device 5 is arranged downstream of the pin blanking device, which is configured to move out of the metal ring 100 placed in the carrier tray 1.

By means of the structure, when the metal ring blanking equipment works, the transferring device 3 firstly translates to be in butt joint with one cache device 2, the cache device 2 places the bearing plate 321 fully loaded with the metal rings 100 and the pins 200 on the transferring device 3, then the pins 200 and the metal rings 100 in the bearing plate 1 can be sequentially taken out by the pin blanking device and the metal ring blanking device 5, finally, the transferring device 3 translates to be in butt joint with the other cache device 2, and the cache device 2 receives the empty bearing plate 1 for use. The working process can replace manual removal of the metal ring 100 and the pin 200 in the bearing plate 1, and the working efficiency is improved.

Referring to fig. 3 and 4, in the present embodiment, a pair of buffer devices 2 may be respectively disposed at the upstream and downstream ends 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.

Referring to fig. d, 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 614 can be further arranged on one of the pair of placing plates 212 forming the placing part, the fool-proof hole 114 which can be inserted with the fool-proof pin 614 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.

Since the positioning holes 113 have an accurate mechanical positioning effect, the diameter of the fool-proof hole 114 can be set to be larger than the outer diameter of the fool-proof pin 614, 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, the 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 the figure, 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 when the bearing disc 1 is placed into the carrying plate is achieved manually, and the difficulty of manual operation is reduced.

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. 4, 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 light shielding plate 232 disposed at the movable end of the lifting mechanism 22, wherein the light shielding plate 232 can move into and out of the detecting slot of the slot-type photoelectric switch 231 along the vertical direction.

When the tray loading mechanism 32 is in the blanking operating position, one first positioning portion 322 located at the tail end of the tray loading mechanism 32 is located at a blanking station to output an empty tray 1, and the other two first positioning portions 322 correspond to the pin blanking device and the metal ring blanking device 5, that is, are located at the pin 200 ring blanking station and the metal ring 100 blanking station, so that two first positioning portions 322 of the three first positioning portions 322 always correspond to the pin blanking device and the metal ring blanking device 5, that is, the pin blanking device and the metal ring blanking device 5 always correspond to an operating state of moving out the pin 200 and the metal ring 100.

In order to further improve the working efficiency, the transfer device 3 provided in this embodiment further includes two jacking mechanisms 33, two jacking mechanisms 33 are provided, the two jacking mechanisms 33 correspond to the two first positioning portions 322 located at the pin blanking device and the metal ring blanking device 5 one by one, and the jacking mechanisms 33 are configured to jack up or lower the carrier tray 1 located at the first positioning portions 322.

As shown in fig. 5, the jacking mechanism 33 can jack up the carrier tray mechanism 32 from the carrier tray 1 carried by the upstream station, so that the carrier tray 1 is separated from the carrier tray mechanism 32 to perform the blanking operation of the metal ring 100 or the pin 200, and in this process, the carrier tray mechanism 32 can be reset to the feeding 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.

As shown in fig. 5, in the present embodiment, the tray loading mechanism 32 further includes a pair of supports 323, and the pair of carrier plates 321 are slidably connected to the pair of supports 323; the transfer mechanism 31 is configured to drive the pair of carrier plates 321 to slide along the supports 323.

In this embodiment, the detecting portion 34 may be disposed by referring to the detecting element 23 in the cache apparatus 2, which is not described herein again.

Referring to fig. 6 to 9, in the present embodiment, the pin blanking device 4 includes a positioning mechanism, a blanking bin 42, an ejection mechanism 43, and a pin sweeping mechanism 44.

The lower bin 42 comprises a bin body 421, the bin body 421 is located above the positioning mechanism, a bottom plate 4211 of the bin body 421 is provided with a plurality of through holes 4212, and the through holes 4212 are in one-to-one correspondence with the pins 200 in the positioned carrier tray 1 along the vertical direction. The ejection mechanism 43 is configured to eject the pins 200 upwards from the bottom of the pockets in a vertical direction, so that the pins 200 move out of the carrier tray 1 and into the lower magazine 42 via the perforations 4212. The sweep mechanism 44 is configured to remove the pins 200 within the lower magazine 42.

By the structure, the pin blanking device 4 can move the pins 200 inserted on the single carrier tray 1 out at one time, move the pins 200 into the blanking bin 42, and finally move the pins 200 out of the blanking bin 42 through the pin sweeping mechanism 44, thereby completing the operation of moving and collecting the pins 200.

It should be noted that the positioning mechanism of the pin blanking device 4 may refer to a second positioning portion provided on the lifting plate 332, that is, in this embodiment, the pin blanking device positions the carrier tray 1 by the transfer device 3. In other alternative embodiments, for example, in an operation scenario where the pin 200 is independently removed by the pin blanking device, the positioning mechanism may be a jig or the like capable of defining the spatial position of the carrier tray 1 by using structural features such as the outline of the carrier tray 1 or the positioning holes 113.

The ejector plate 431 is vertically movable, and when it is in the lowered position, the ejector pins 432 are located below the carrier tray 1, and when the ejector plate 431 is moved upward to the raised position, the respective ejector pins 432 push the pins 200 one-to-one, moving the pins 200 out of the carrier tray 1.

Specifically, in this embodiment, the lower bin 42 is driven by a lifting platform 45 to lift, when the lower bin 42 is at the sinking position, the bottom plate 4211 of the lower bin 42 just contacts or approaches to the bearing tray 1 to be moved out of the pin 200, so that each through hole 4212 corresponds to each pin 200 on the bearing plate 321, and the bearing tray 1 is restricted from moving upward, then, the ejecting plate 431 of the ejecting mechanism 43 is ejected to the lifting position by the ejecting plate 332 at the blanking station of the pin 200 to eject the pin 200, after the pin sweeping mechanism 44 is moved out of the pin 200 in the lower bin 42, the lifting platform 45 drives the lower bin 42 to lift, so as to avoid the transfer mechanism 31 and the bearing tray 1.

In this embodiment, the bottom plate 4211 is further provided with an anti-banding portion 4213, and the anti-banding portion 4213 is configured to hold the metal ring 100 on the carrier tray 1 when the pin 200 is moved out of the carrier tray 1. The anti-strip portion 4213 may comprise a blocking piece made of a flexible material such as silicone, and the blocking piece is preferably disposed on the bottom side of the bottom plate 4211, and partially blocks the through hole 4212, when the pin 200 is pushed by the lifting plate 332, the head of the pin 200 pushes the flexible blocking piece to move into the through hole 4212, and the blocking piece is inserted between the head of the pin 200 and the metal ring 100 after being deformed, so as to block the metal ring 100, and prevent the metal ring 100 from being lifted off the carrier tray 1 by being rubbed by the pin 200.

Further, the blocking pieces may be symmetrically disposed on two axial sides of the through hole 4212, that is, two sides of the bottom end of each through hole 4212 are partially blocked by the blocking pieces, so as to prevent the metal ring 100 from blocking the blocking piece disposed only on one side of the through hole 4212 in an inclined posture, and to ensure that the metal ring 100 does not move into the through hole 4212.

As shown in fig. 9, in the present embodiment, the blocking pieces are strip-shaped, and multiple rows of blocking pieces are matched to block multiple rows of through holes 4212, and each blocking piece is independent from another and can be replaced independently when a single blocking piece is damaged.
