Description

Technical Field

[0001] This utility model belongs to the technical field of crystal expansion ring equipment, and more specifically, it relates to a mother-daughter crystal expansion ring separation device. Background Technology

[0002] An expansion ring, consisting of two concentric daughter rings and a mother ring, is a commonly used tool in the LED industry, primarily for sorting and processing LED chips or wafers. During LED production, the wafer film needs to be expanded to ensure uniform expansion of the arrayed chips attached to it. The expanded wafer film needs to be fixed using an expansion ring, and excess wafer film is removed. In this process, after the wafer film is fed onto the wafer expander, the daughter and mother rings of the expansion ring must first be separated before being fed separately into the expander. Currently, existing expansion... The separation of the mother ring and daughter ring of the crystal ring is usually done manually by disassembling the daughter ring and mother ring of the crystal expansion ring and then manually transporting the daughter ring and mother ring to the wafer expander. However, the above manual separation and transportation method is not only time-consuming and labor-intensive, but also difficult for operators to manually disassemble because the mother ring of the outer ring of the assembled crystal expansion ring is tightly held on the daughter ring of the inner ring of the crystal expansion ring, which affects the separation efficiency. Moreover, the long-term manual disassembly of the crystal expansion ring can easily lead to finger injuries or partial damage to the daughter ring and mother ring. Overall, there are problems of low separation efficiency, poor separation effect and low safety. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a mother-daughter crystal expansion ring separation device with a high degree of automation and the advantages of high separation efficiency, good separation effect and high safety.

[0004] To achieve the above objectives, the present invention provides the following technical solution:

[0005] A mother-daughter crystal expansion ring separation device includes a separation platform with a through groove. A fixed seat is rotatably connected within the through groove. The upper surface of the fixed seat has a groove at its bottom for placing only the mother ring. A feeding hole is coaxially formed at the bottom of the groove, located directly below the unseparated daughter ring. A limiting ring for pressing down and fixing the upper end of the mother ring and a pressing plate for pressing down and separating the daughter ring are coaxially arranged above the fixed seat. The pressing plate is located directly above the feeding hole. A first lifting mechanism for driving the limiting ring to rise and fall and a second lifting mechanism for driving the pressing plate to rise and fall toward the feeding hole are mounted on the separation platform. A first rotating component for driving the fixed seat to rotate 180° up and down is installed on one side of the separation platform. A separation box is installed at the bottom of the separation platform. The top of the separation box has a feed port communicating with the through groove. A guide plate is rotatably connected inside the separation box. A discharge port is formed on each opposite side of the separation box. A second rotating component for driving the guide plate to rotate and tilt toward the discharge port is installed in the separation box.

[0006] Further configuration: The first lifting mechanism includes a set of brackets, a set of mounting plates, and a set of upper electric push rods. The bottom of the brackets is mounted on the separation platform, and the upper electric push rods are mounted on the top of the brackets through the mounting plates. The set of brackets are located on opposite sides of the fixed seat, and the top rods of the set of upper electric push rods are detachably connected to both sides of the limiting ring.

[0007] Further configuration: A set of guide rods is connected to both sides of the upper end of the limiting ring, and the mounting plate has guide holes for the guide rods to pass through.

[0008] Further configuration: The lower pressure plate includes several connectors, a coaxially arranged intermediate plate, and several outer rings; the diameters of the outer rings increase sequentially, and they are nested together radially from the inside to the outside. The outer ring with the smallest diameter is nested on the outer side of the intermediate plate. Adjacent outer rings, the intermediate plate and the inner outer ring, and the outer outer ring and the fixed base are detachably connected by the connectors. The upper end face of each outer ring is provided with a limiting groove with a diameter smaller than the diameter of the groove for placing the mother ring; there are several limiting rings with progressively increasing diameters. One limiting ring is placed in each limiting groove. An adjustment component for adjusting the upper electric push rod to move radially along the limiting ring is provided between the top of the bracket and the mounting plate.

[0009] Further configuration: The adjustment assembly includes a set of adjustment plates and a set of adjustment bolts, each with a wing nut. The two adjustment plates are respectively installed on both sides of the top of the bracket. The sides of the adjustment plates have several sets of threaded holes along the radial direction of the limiting ring for the adjustment bolts to pass through. The mounting plate has mounting holes that communicate with the threaded holes and allow the adjustment screw to pass through. The upper electric push rod and the mounting plate are both located between the two adjustment plates. A slider is connected to the top of the mounting plate. The top of the bracket has a groove for the slider to move radially along the limiting ring.

[0010] Further configuration: The second lifting mechanism includes a support frame and a first lifting cylinder. The bottom of the support frame is fixedly connected to the separation platform, and the first lifting cylinder is fixedly installed on the top of the support frame. The top rod of the first lifting cylinder is detachably connected to the middle of the lower pressure plate.

[0011] Further configuration: A sub-ring conveyor and a mother ring conveyor are respectively provided on the two opposite outer sides of the separation box, and the sub-ring conveyor and the mother ring conveyor are respectively located below the two discharge ports.

[0012] Further configuration: The second rotating component is a stepper motor, and a rotating shaft is rotatably connected to each of the other opposite sides of the separation box. The two sides of the guide plate are respectively fixedly connected to the two rotating shafts. The stepper motor is installed on the outer side of the separation box, and the drive end of the stepper motor passes through the separation box and is fixedly connected to one of the rotating shafts.

[0013] Further configuration: The second rotating component includes a connecting rod, a support plate, and a set of lower electric push rods. The lower electric push rods are located on the other two sides of the guide plate. The two ends of the connecting rod are respectively hinged to the bottom of the guide plate and the top rod of one of the lower electric push rods. The support plate is fixedly connected to the top rod of the other lower electric push rod. A fixed plate is slidably connected to the upper and lower sides inside the separation box. A U-shaped rotating frame is fixedly installed in the middle of the fixed plate. The two vertical ends of the rotating frame are rotatably connected to the two sides of the guide plate. The lower electric push rods are all installed on the fixed plate. A second lifting cylinder that drives the fixed plate to rise and fall is installed at the bottom of the separation box.

[0014] In summary, this invention utilizes a separation platform, a fixing base, a groove, and a feeding hole to place the expansion ring within the groove. The bottom of the mother ring is supported by the bottom of the groove, and the daughter ring of the expansion ring is suspended directly above the feeding hole, thus initially limiting the position of the mother ring. A first lifting mechanism and a limiting ring are used to fix the mother ring of the expansion ring between the limiting ring and the bottom of the groove, achieving a secondary fixation of the mother ring. A second lifting mechanism and a pressure plate are used to press down the daughter ring and push the separated daughter ring into the feeding hole, achieving automatic separation of the daughter ring and mother ring of the expansion ring.

[0015] The system utilizes a separation box, a feed inlet, a guide plate, and a second rotating component. The guide plate receives the sub-rings falling from the discharge hole. The driving end of the second rotating component rotates forward, causing the guide plate to tilt and convey the sub-rings towards one of the discharge ports. The sub-rings fall through this discharge port onto the sub-ring conveying device, thus automatically removing and conveying the separated sub-rings. The first rotating component causes the fixed seat to flip, with the groove opening facing downwards. Under gravity, the mother ring falls onto the guide plate, automatically unloading the separated mother ring. The second rotating component rotates in the opposite direction, causing the guide plate to tilt and convey the mother ring towards the other discharge port. The mother ring falls through this other discharge port onto the mother ring conveying device, thus automatically removing and conveying the separated mother ring. This invention features a high degree of automation, high separation efficiency, good separation effect, and high safety. Attached Figure Description

[0027] To explain the technical content, objectives, and effects of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings. It should be noted that the terms "upper" and "lower" used in the following description refer to the attached drawings. Figure 2 The direction in the middle, the words "bottom" and "top" refer to the attached Figure 2The direction of the center of a specific component is the same as the direction in which the conveying device transports the chicken gizzards, as mentioned throughout the text, which is the same as the direction in which the conveying device transports the chicken gizzards.

[0028] Please refer to Figures 1 to 5 As shown, the first embodiment provided by this utility model is as follows:

[0029] A mother-daughter ring separation device includes a separation platform 1, a through groove 2 on the separation platform 1, a fixed base 3 rotatably connected in the through groove 2, a groove 4 on the upper end face of the fixed base 3 for placing only the mother ring a at the bottom, a feeding hole 5 coaxially opened at the bottom of the groove 4 directly below the unseparated daughter ring b, a limiting ring 6 for pressing down and fixing the upper end of the mother ring a and a pressing plate 7 for pressing down and separating the daughter ring b are coaxially arranged above the fixed base 3; the pressing plate 7 is located directly above the feeding hole 5, and a drive limit is mounted on the separation platform 1. The first lifting mechanism for lifting the positioning ring 6 and the second lifting mechanism for driving the lower pressure plate 7 to lift towards the discharge hole 5; a first rotating component 30 for driving the fixed seat 3 to rotate 180° up and down is installed on one side of the separation table 1; a separation box 8 is installed at the bottom of the separation table 1; the top of the separation box 8 is provided with a feed port communicating with the through groove 2; a guide plate 9 is rotatably connected inside the separation box 8; a discharge port 10 is opened on both opposite sides of the separation box 8; a second rotating component 38 for driving the guide plate 9 to rotate and tilt towards the discharge port 10 is installed in the separation box 8.

[0030] As described above, when it is necessary to separate the daughter ring b and the mother ring a of the expansion ring, firstly, the mother ring a of the expansion ring is placed in the groove 4, so that the daughter ring b of the expansion ring is suspended directly above the feeding hole 5, thus initially limiting the position of the mother ring a of the expansion ring; then, the first lifting mechanism is activated, and the driving end of the first lifting mechanism drives the limiting ring 6 to descend towards the groove 4 until the bottom of the limiting ring 6 presses against the upper end face of the mother ring a of the expansion ring, and the mother ring a of the expansion ring is fixedly limited between the limiting ring 6 and the bottom of the groove 4. In the middle, the mother ring a of the expansion ring is fixed and limited for a second time, so as to prevent the mother ring a from being tilted towards the feeding hole 5 by the child ring b when the lower pressure plate 7 presses down to separate the child ring b. Then, the second lifting mechanism is activated. The driving end of the second lifting mechanism drives the lower pressure plate 7 to descend towards the feeding hole 5. The lower pressure plate 7 first contacts the top surface of the child ring b in the groove 4. As the lower pressure plate 7 continues to descend, it pushes the child ring b downward into the feeding hole 5, thereby realizing the automatic separation of the child ring b and the mother ring a of the expansion ring.

[0031] Afterwards, the child ring b, separated from the mother ring a, falls onto the guide plate 9 inside the separation box 8 through the discharge hole 5 and the feed inlet under the action of gravity. The second rotating component 38 is then activated, its drive end rotating forward, causing the guide plate 9 to tilt towards one of the discharge ports 10. Under the action of gravity, the child ring b on the guide plate 9 slides down from the guide plate 9 to the discharge port 10, and then falls onto the existing child ring b collection box or child ring conveying device 28, thus automatically removing the separated child ring b. Then, the drive ends of the second rotating component 38 and the first lifting mechanism simultaneously reset, causing the guide plate 9 to rotate from the tilted state back to a horizontal position. The lowering mechanism drives the limiting ring 6 to rise and reset to its initial position, leaving room for the fixed seat 3 to rotate. Then, the first rotating component 30 is activated. The driving end of the first rotating component 30 drives the fixed seat 3 to rotate 180° radially downward along the discharge hole 5, so that the groove 4 of the fixed seat 3 faces downward. Under the action of gravity, the mother ring a falls onto the guide plate 9. Finally, the second rotating component 38 is activated. The second rotating component 38 rotates in the opposite direction, driving the guide plate 9 to tilt towards the other discharge port 10. Under the action of gravity, the mother ring a on the guide plate 9 tilts downward along the guide plate 9 and falls through the other discharge port 10 onto the existing mother ring a collection box or mother ring conveying device 29, thus realizing the automatic removal of the separated mother ring a. In this embodiment, the first rotating component 30 is a stepper motor, not limited to this rotary drive structure. Other rotary drive structures that can drive the fixed seat 3 to rotate 180° forward and backward are also acceptable.

[0032] Furthermore, the first lifting mechanism includes a set of brackets 11, a set of mounting plates 12, and a set of upper electric push rods 13. The bottom of the brackets 11 is mounted on the separation platform 1, and the upper electric push rods 13 are mounted on the top of the brackets 11 through the mounting plates 12. The set of brackets 11 are located on opposite sides of the fixed base 3, and the top rods of the set of upper electric push rods 13 are detachably connected to both sides of the limiting ring 6.

[0033] As described above, when the mother ring a of the expansion ring placed in the groove 4 needs to be pressed down between the bottom of the groove 4 and the limiting ring 6, the two electric push rods are activated. The external controller controls the top rods of the two upper electric push rods 13 to extend synchronously, driving the limiting ring 6 to move downward toward the groove 4. When the top rods of the two upper electric push rods 13 extend synchronously to the preset value, the limiting ring 6 descends to press against the upper end face of the mother ring a. When the lower pressure plate 7 presses the daughter ring b of the expansion ring into the feeding hole 5, that is, when the daughter ring b separates from the mother ring a, the top rod of the upper electric push rod 13 retracts and resets, driving the limiting ring 6 to move upward and reset to the initial position, thus automatically driving the limiting ring 6 to rise and fall. By setting the limiting ring 6 to be detachably connected to the top rod of the upper electric push rod 13, it is convenient for users to disassemble and replace the limiting ring 6 during maintenance or cleaning.

[0034] Furthermore, to ensure the stability of the two electric push rods driving the limit ring 6 to rise and fall synchronously, a set of guide rods 14 can be connected to both sides of the upper end of the limit ring 6, and the mounting plate 12 is provided with guide holes 15 for the guide rods 14 to pass through.

[0035] As can be seen from the above description, during the process of the upper electric push rod 13 driving the limit ring 6 to rise and fall, the guide rod 14 passes through the guide hole 15 and rises and falls in a directional manner with the limit ring 6, which plays the role of ensuring that the two upper electric push rods 13 drive the limit ring 6 to rise and fall in a directional manner synchronously.

[0036] The first lifting mechanism mentioned above is not limited to using two electric push rods. Other existing synchronous elements (not shown in the figure), such as two servo cylinders or two cylinders, plus a synchronous valve or proportional valve, can also be used to replace the two electric push rods, as long as they can achieve a synchronous lifting structure that synchronously drives the limit ring 6 to lift.

[0037] Furthermore, the second lifting mechanism includes a support frame 26 and a first lifting cylinder 27. The bottom of the support frame 26 is fixedly connected to the separation platform 1, and the first lifting cylinder 27 is fixedly installed on the top of the support frame 26. The top rod of the first lifting cylinder 27 is detachably connected to the middle of the lower pressure plate 7.

[0038] As described above, when it is necessary to separate the sub-ring b from the mother ring a by driving the lower pressure plate 7, it is only necessary to activate the first lifting cylinder 27. The push rod of the first lifting cylinder 27 extends downward, driving the lower pressure plate 7 to descend towards the material discharge hole 5. During the descent of the lower pressure plate 7, the lower pressure plate 7 will first contact the top surface of the sub-ring b in the groove 4. As the lower pressure plate 7 continues to descend, the lower pressure plate 7 pushes the sub-ring b downward until the sub-ring b separates from the mother ring a. Under the action of gravity, the sub-ring b first falls into the material discharge hole 5, and then falls from the material discharge hole 5 through the feed inlet into the separation box 8, realizing the automatic separation of the sub-ring b and the mother ring a of the expansion ring. By setting the lower pressure plate 7 to be detachably connected to the push rod of the first lifting cylinder 27, it is convenient for users to disassemble and replace the lower pressure plate 7 during maintenance or cleaning.

[0039] Furthermore, a sub-ring conveyor 28 and a mother ring conveyor 29 are respectively provided on the opposite outer sides of the separation box 8. The sub-ring conveyor 28 and the mother ring conveyor 29 are located below the two discharge ports 10. In this embodiment, the sub-ring conveyor 28 and the mother ring conveyor 29 are both belt conveyors, and are not limited to this conveying structure. Other conveying structures, such as plate conveyors, are also acceptable as long as they can automatically convey the sub-ring b or the mother ring a to the next process.

[0040] The sub-ring conveyor 28 and the mother ring conveyor 29 are used to automatically transport the sub-ring b and mother ring a, which are discharged from the two discharge ports 10, to the next process. According to the user's needs, if only the separated sub-ring b and mother ring a are collected, the sub-ring conveyor 28 can be replaced with a sub-ring b collection box to collect the sub-ring b discharged from one discharge port 10, and the mother ring conveyor 29 can be replaced with a mother ring a collection box to collect the mother ring a discharged from the other discharge port 10.

[0041] Furthermore, the second rotating component 38 is a stepper motor, and a rotating shaft 31 is rotatably connected to each of the other opposite sides of the separation box 8. The two sides of the guide plate 9 are fixedly connected to the two rotating shafts 31 respectively. The stepper motor is installed on the outer side of the separation box 8, and the drive end of the stepper motor passes through the separation box 8 and is fixedly connected to one of the rotating shafts 31.

[0042] As described above, when the separated sub-ring b falls onto the guide plate 9 through the discharge hole 5 and the feed inlet, the stepper motor is started. The drive end of the stepper motor rotates in the forward direction, causing the guide plate 9 to tilt and rotate towards the discharge port 10 near which the sub-ring b is discharged. The guide plate 9 rotates to the side closest to the discharge port 10, and under the action of gravity, the sub-ring b falls from the guide plate 9 downwards through the discharge port 10 onto the sub-ring conveying device 28. The stepper motor then drives the guide plate 9 to rotate and reset until it is parallel to the fixed seat 3 again, thus automatically picking up, placing, and conveying the separated sub-ring. The function of the sub-ring b; similarly, when the fixed seat 3 is flipped over, the mother ring a falls onto the guide plate 9 through the feed port under the action of gravity. Then, the stepper motor is started, and the drive end of the stepper motor rotates in the opposite direction, causing the dead plate to tilt toward the other discharge port 10 near the discharge port 10 of the mother ring a. Under the action of gravity, the mother ring a falls from the tilted guide plate 9 through the discharge port 10 onto the mother ring conveying device 29. By setting the limit ring 6 to be detachably connected to the top rod of the upper electric push rod 13, it is convenient for the user to disassemble and replace the limit ring 6 during maintenance or cleaning, so as to automatically pick up and place and convey the separated mother ring a.

[0043] In addition, to prevent the mother ring a from falling accurately into the separation box 8 through the through groove 2 during the flipping process of the fixed seat 3, an arc-shaped baffle structure (not shown in the figure) can be installed on the separation table 1.

[0044] Example 2 differs from Example 1 in that, as Figure 6 and Figure 7As shown, the lower pressure plate 7 includes several connectors 16, a coaxially arranged intermediate plate 17, and several outer rings 18; the diameters of the several outer rings 18 increase sequentially, and they are nested together from the inside to the outside along their radial direction. The outer ring 18 with the smallest diameter is nested on the outer side of the intermediate plate 17. Adjacent outer rings 18, the intermediate plate 17 and the inner outer ring 18, and the outer outer ring 18 and the fixed base 3 are all detachably connected by connectors 16. The upper end face of each outer ring 18 is provided with a limiting groove 19 with a diameter smaller than that of the groove 4 for the placement of the mother ring a; there are several limiting rings 6 with increasing diameters. One limiting ring 6 is placed in each limiting groove 19. An adjustment component is provided between the top of the bracket 11 and the mounting plate 12 for adjusting the upper electric push rod 13 to move radially along the limiting ring 6.

[0045] In this embodiment, the connector 16 is a connecting plate. The detachable connection of the connector 16 adopts bolts, screw holes and threaded grooves. Threaded grooves are opened in the fixing seat 3, outer ring 18 and intermediate plate 17. Screw holes are opened on the connector 16. It is not limited to this detachable connection structure. Other detachable structures such as snap-fit ​​and plug-in are also acceptable, as long as the connector 16 can be detachably connected between adjacent outer rings 18, between the intermediate plate 17 and the inner outer ring 18, and between the outer outer ring 18 and the fixing seat 3.

[0046] As described above, when separating the sub-ring b and the mother ring a from expansion rings of the same thickness but different diameters, firstly, simply remove the outer ring 18 corresponding to the diameter of the mother ring a and place them inside the groove 4, or remove the outer ring 18 of the corresponding diameter and place it in the groove 4 along with all outer rings 18 larger than that diameter. The bottom of the removed outer ring 18 is placed on top of the feed hole 5. Then, remove the limiting ring 6 from the top rod of the upper electric push rod 13 and place it inside the groove 4. Then, use the connector 16 to detachably connect the outer outer ring 18 to the fixed seat 3 and the adjacent outer rings 18 together. After that, use the adjusting component to adjust the diameter between the center of the upper electric push rod 13 and the feed hole 5. The distance is adjusted so that the top rod of the upper electric push rod 13 is directly above the limiting groove 19 corresponding to the diameter of the mother ring a to be separated. Then, the limiting ring 6 in the limiting groove 19 corresponding to the diameter of the mother ring a to be separated is taken out and detachably connected to the top rod of the upper electric push rod 13. Finally, the mother ring a to be separated is placed in the limiting groove 19 of the corresponding diameter. The top rod of the upper electric push rod 13 in Embodiment 1 drives the limiting ring 6 to press down and fix the upper end of the mother ring a of the expanding ring. The second lifting mechanism drives the intermediate disk 17 or the intermediate disk 17 and the remaining outer ring 18 to press down and push the daughter ring b of the expanding ring until the daughter ring b is separated from the mother ring a. This realizes the function of separating the daughter ring b and the mother ring a for expanding rings of the same thickness but different diameters.

[0047] Furthermore, the adjustment assembly includes a set of adjustment plates 20 and a set of adjustment bolts 21, each with a wing nut. The two adjustment plates 20 are respectively installed on both sides of the top of the bracket 11. The sides of the adjustment plates 20 are radially provided with several sets of threaded holes 22 for the adjustment bolts 21 to pass through. The mounting plate 12 is provided with mounting holes 23 that communicate with the threaded holes 22 and allow the adjustment screw to pass through. The upper electric push rod 13 and the mounting plate 12 are both located between the two adjustment plates 20. The top of the mounting plate 12 is connected to a slider 24. The top of the bracket 11 is provided with a groove 25 for the slider 24 to move radially along the limit ring 6.

[0048] As can be seen from the above description, when it is necessary to adjust the radial distance between the upper electric push rod 13 and the center of the discharge hole 5, simply loosen the wing nut, remove the adjusting bolt 21 from the adjusting plate 20 and the mounting plate 12, and then use the slider 24 in the groove 25 to slide the upper electric push rod 13 radially along the limiting ring 6 until the mounting hole 23 communicates with the threaded hole 22 at the corresponding distance. After passing the adjusting bolt 21 through the threaded hole 22 and the mounting hole 23, tighten the wing nut again. Use the adjusting bolt 21 and the wing nut to detachably connect the mounting plate 12 between a set of adjusting plates 20, so as to realize the radial adjustment function of the upper electric push rod 13 along the discharge hole 5.

[0049] The adjustment assembly is not limited to the above-mentioned adjustment plate 20 plus adjustment bolt 21 structure. Other automatic translation adjustment structures, such as linear guide rails with stepper motors (not shown in the figure), are also acceptable, as long as the adjustment structure can achieve the radial adjustment of the upper electric push rod 13 along the limiting ring 6 (which is also the feeding hole 5).

[0050] Example 3 differs from Examples 1 and 2 in that, as Figures 8 to 10 As shown, the second rotating component 38 includes a connecting rod 33, a support plate 37, and a set of lower electric push rods 32. The lower electric push rods 32 are located on the other two sides of the guide plate 9. One end of the connecting rod 33 is hinged to the top rod of one of the lower electric push rods 32, and the other end of the connecting rod 33 is hinged to the bottom of the guide plate 9. The support plate 37 is fixedly connected to the top rod of the other lower electric push rod 32. A fixed plate 34 is slidably connected to the separation box 8. A U-shaped rotating frame 35 is fixedly installed in the middle of the fixed plate 34. The two vertical ends of the rotating frame 35 are rotatably connected to the two sides of the guide plate 9. The lower electric push rods 32 are all installed on the fixed plate 34. A second lifting cylinder 36 is installed at the bottom of the separation box 8 to drive the fixed plate 34 to rise and fall. To facilitate the rising and falling of the lower electric push rods 32, a power supply (not shown in the figure) for supplying power to the lower electric push rods 32 is installed on the fixed plate 34.

[0051] As can be seen from the above description, when it is necessary to press down to separate the sub-ring b and the mother ring a of the expansion ring, the guide plate 9 is located at the feed inlet under the drive of the second lifting cylinder 36. The upper end face of the guide plate 9 contacts the bottom end face of the fixed seat 3 to support the fixed seat 3. After the sub-ring b separates from the mother ring a and falls onto the guide plate 9, the top rod of the second lifting cylinder 36 retracts and resets, driving the fixed plate 34, the lower electric push rod 32, the rotating frame 35 and the guide plate 9 to descend to the initial position.

[0052] Then, the top rod of the lower electric push rod connected to the support plate retracts, driving the support plate down to the preset position. Then, the top rod of the lower electric push rod 32, which is hinged to the connecting rod 33, extends, driving the connecting rod 33 to extend, thereby driving the guide plate 9 to tilt and rotate downwards towards the discharge port 10 of the feed ring b. This achieves the function of driving the guide plate to tilt and discharge material towards the corresponding discharge port. Until the guide plate 9 rotates downwards to the discharge port 10 of the feed ring b, the top rod of the lower electric push rod 32 stops retracting. After the feed ring b falls from the discharge port 10 to the outside of the separation box 8, the top rod of the lower electric push rod 32 retracts and resets to the point where the guide plate 9 is parallel to the fixed seat 3 again. The top rod of the other lower electric push rod 32 extends, driving the support plate to support the reset fixed seat 3.

[0053] Similarly, when the mother ring a falls onto the guide plate 9, the lower electric push rod 32, which is hinged to the connecting rod 33, retracts, causing the other side of the guide plate 9 to rotate downwards near the discharge port 10 for the mother ring a. After the mother ring a is discharged, the push rod of the lower electric push rod 32 extends, causing the connecting rod 33 to reset, thereby causing the upper end face of the guide plate 9 to be parallel to the upper end face of the fixed seat 3 again. Before the next wheel, the daughter ring b and the mother ring a separate, the push rod of the second lifting cylinder 36 drives the guide plate 9 to rise again to contact the bottom end face of the fixed seat 3, and repeats the above steps. When the push rod of the second lifting cylinder 36 drives the guide plate 9 to rise to the feed port, only before the daughter ring b is discharged, when the daughter ring b is discharged from the discharge port 10 to the mother ring a, the push rod of the second lifting cylinder 36 and the guide plate 9 both descend to a position away from the feed port.

[0054] In summary, compared with existing technologies, this utility model has a high degree of automation and advantages such as high separation efficiency, good separation effect, and high safety. The working process is as follows: When it is necessary to separate the sub-ring b and the mother ring a of the expansion ring, firstly, the expansion ring is placed in the groove 4, and the bottom of the groove 4 is used to support the mother ring a. The sub-ring b of the expansion ring is suspended directly above the feed hole 5, which initially limits the position of the mother ring a. Then, the first lifting mechanism is activated, which drives the limiting ring 6 to descend and press down on the upper end face of the mother ring a, fixing the mother ring a between the limiting ring 6 and the bottom of the groove 4, so as to prevent the mother ring a from being tilted towards the feed hole 5 by the sub-ring b when the lower pressure plate 7 presses down to separate the sub-ring b. Then, the second lifting mechanism is activated, which drives the lower pressure plate 7 to press down on the sub-ring b until the sub-ring b is separated from the mother ring a. Under the action of gravity, the sub-ring b The material falls onto the guide plate 9 through the feed inlet; then, the driving end of the second rotating member 38 drives the guide plate 9 to tilt and rotate towards one of the discharge ports 10, and the sub-ring b slides down from the guide plate 9 through the discharge port 10 and falls onto the sub-ring conveying device 28, thus realizing the function of automatically taking out and conveying the separated sub-ring b; after that, the driving end of the second rotating member 38 drives the guide plate 9 to rotate and reset to the horizontal position, and starts the first rotating member 30, which drives the fixed seat 3 to rotate 180° radially downward along the discharge hole 5, and the mother ring a falls onto the guide plate 9 under the action of gravity; finally, the driving end of the second rotating member 38 rotates in the opposite direction, driving the guide plate 9 to tilt towards the other discharge port 10, and the mother ring a slides down from the guide plate 9 through the other discharge port 10 and falls onto the mother ring conveying device 29, thus realizing the function of automatically taking out and conveying the separated mother ring a.
