Description

Technical Field

[0001] This invention relates to the field of smart glasses manufacturing equipment technology, specifically to an automatic O-ring support and assembly equipment for smart glasses buttons. Background Technology

[0002] Current smart glasses also mimic the appearance and structure of smartphones, incorporating control buttons for volume, power, and other functions. (See the instruction manual for details.) Figure 16 and Figure 17 Many smart glasses on the market feature a long, rectangular button on the temple, with two pressing ends inside. Each pressing end engages with a spring switch built into the temple, enabling mechanical control of the smart glasses. However, these smart glasses require sealing material around the mounting groove of the long, rectangular button to improve waterproofing. This necessitates fitting an O-ring onto the pressing end of the button. However, the cylindrical pressing end has upper and lower annular grooves on its outer circumference. The O-ring must pass through the upper groove and be installed into the lower groove. Current manufacturing processes often result in the O-ring being misfitted into the upper groove, leading to low installation efficiency, low quality control, and a high scrap rate after assembly, placing a heavy workload on the quality control department. Therefore, there is an urgent need for automated equipment to precisely fit the extremely small O-ring into the lower annular groove of the pressing end of the long, rectangular button, thereby improving the O-ring installation quality rate, efficiency, and overall assembly efficiency of the smart glasses temple and the long, rectangular button. Summary of the Invention

[0003] The problem this invention aims to solve is that the O-rings for the lower ring groove of the pressing end of the long strip button on the temple of existing smart glasses are often misfitted, with the O-rings being misfitted into the upper ring groove. Furthermore, the O-ring installation is inefficient, with a low pass rate, and poor assembly between the O-ring and the pressing end leading to a high scrap rate, placing a heavy workload on the quality inspection department. This invention proposes an automatic O-ring fitting and installation device.

[0004] The technical solution adopted to solve the above problems is:

[0005] An automatic O-ring support assembly device for smart glasses buttons is proposed, including...

[0006] O-ring feeding assembly

[0007] An automatic transfer assembly consisting of X-axis and Z-axis electric cylinder slides.

[0008] An automatic O-ring threading, supporting, and pressing assembly, driven by an automatic transfer component, includes an assembly frame, calibration guide pins, threading needles, supporting cylinders, O-ring peeling blocks, a needle-pulling cylinder for retracting the threading needles, a material-peeling cylinder for peeling off the O-rings, a linear guide rail, and a connecting arm.

[0009] A support platform used to mate with an O-ring on the top of a loop-threading needle and thread it onto a support cylinder.

[0010] A positioning platform for assembling O-rings on buttons.

[0011] And the push-pressing assembly of the auxiliary clamping button,

[0012] The O-ring feeding assembly includes a vibratory feeder containing several O-rings for stable feeding, a distribution plate, a spreading platform, and an auxiliary needle threading mechanism.

[0013] The discharge port of the vibratory feeder is connected to a distribution plate. The distribution plate has several evenly spaced feeding tracks. The ends of the feeding tracks terminate at the loading trough of the spreading platform. The O-rings being vibrated and fed are stably and evenly fed onto the spreading platform along the feeding tracks.

[0014] The material feeding platform has several O-ring feeding slots arranged in an array. The sides of the feeding slots are provided with bushings to facilitate the precise insertion of the calibration guide pins for positioning. Several feeding slots are also provided with auxiliary needle threading mechanisms on one side.

[0015] The auxiliary needle-threading mechanism includes an auxiliary needle-threading cylinder, a needle-threading plate, and a linear guide rail. The auxiliary needle-threading cylinder drives the needle-threading plate to move back and forth. The needle-threading plate has needle-threading slots on one side of the feeding slot, with the same number of slots as the feeding slots. The needle-threading slots have guide chamfers to facilitate precise positioning of the loop-threading needle. The loop-threading needle is guided into the O-ring in the feeding slot and pressed down to place the O-ring around the outer ring of the loop-threading needle.

[0016] The upper section of the threading needle is cylindrical, and the lower section is conical. The outer ring of the upper section has several keyways arranged in a circular array, which are in clearance fit with the keyway holes in the inner ring of the support cylinder. The threading needle is freely extended and retracted along the axial direction of the support cylinder by a needle-pulling cylinder through a connecting plate. The lower section of the threading needle is used to open the inner hole of the O-ring.

[0017] The outer ring of the support ring cylinder is positioned by a limiting plate set on the assembly frame to ensure its positioning accuracy. A stepped frustum is provided at the lower part of the support ring cylinder. The stepped frustum divides the outer ring of the support ring cylinder into an assembly ring for receiving the O-ring that has been opened. The inner ring of the assembly ring is also provided with a countersunk hole for fitting the pressing end.

[0018] The assembly frame is used to position the push plate, needle-pulling cylinder, stripping cylinder, linear guide rail, and calibration guide pin.

[0019] The peeling cylinder drives the connecting arm, which is defined by a linear guide rail, to extend and retract. The connecting arm is connected to the peeling block, which has a peeling hole that matches the assembly ring shaft hole of the support cylinder. Under the push of the peeling cylinder, the peeling block pushes the O-ring supported by the assembly ring downwards to peel it off, thus assembling the O-ring with the pressing end.

[0020] The support platform includes a clamping platform, a linear slide rail, several sets of opposing clamping blocks and clamping springs. The clamping blocks are fitted onto the linear slide rail and pushed linearly by the clamping springs. The clamping blocks are arranged symmetrically on the left and right sides, pushing in opposite directions, with a gap between the left and right clamping blocks larger than the diameter of the lower end of the threading needle. This allows the threading needle to be pressed downwards smoothly and lifted upwards along the threading needle by the clamping blocks, smoothly reaching the assembly ring.

[0021] The positioning platform includes a support platform, an assembly platform, a vertical pressing mechanism for positioning the button, and a horizontal clamping mechanism. The assembly platform is used to assemble the button with an O-ring. It has a built-in support block for positioning the O-ring to be assembled. The support block is designed according to the bottom contour of the button and is pushed upward by a support spring.

[0022] Furthermore, the vertical pressing mechanism includes a pressing cylinder, a cam block, a lifting frame controlled by a guide rod and guide sleeve assembly, a sliding seat, and several pressing arms connected to the lifting frame. The pressing cylinder drives the cam block to move horizontally. The upper surface of the cam block is provided with an involute pushing surface. The pushing surface cooperates with the rollers designed below the lifting frame to drive the lifting frame to move up and down. The lifting frame is symmetrically provided with guide rod and guide sleeve assemblies and return springs on both sides. The guide sleeves are provided on both sides of the sliding seat to limit the lifting frame to only move up and down. The pressing arms press and lock the button with the O-ring to be fitted. The sliding seat cooperates with the horizontal clamping mechanism to achieve horizontal movement.

[0023] Furthermore, the horizontal clamping mechanism includes a clamping cylinder, a clamping plate, and a slider rail assembly that limits the horizontal linear sliding of the sliding seat. The clamping cylinder drives the clamping plate to push linearly. The front end face of the clamping plate is provided with a positioning groove that fits the pressing end of the O-ring to be fitted, thereby positioning the pressing end face on this side.

[0024] Furthermore, the sliding seat is also connected to the clamping plate. The clamping cylinder drives the sliding seat, which in turn drives the lifting frame to move horizontally, thereby controlling the pressure arm to move horizontally to make room for the button.

[0025] Furthermore, the push-pressing assembly is positioned on the clamping plate and includes a push plate controlled by a linear guide rail, pressure bars, a booster spring for pushing the pressure bars, and a push cylinder. The push cylinder drives the push plate to slide towards the pressing end of the button with the O-ring to be inserted, and the push end face of several pressure bars embedded in the push plate faces the other end face of the pressing end, clamping the pressing end relative to the clamping plate.

[0026] Furthermore, the vibratory feeder is controlled by a drawer mechanism to achieve docking and separation with the material distribution plate, facilitating the filling of O-rings into the vibratory feeder. The drawer mechanism includes a drawer plate, a drawer slide assembly, a locking cylinder, and a locking pin. The locking cylinder drives the locking pin to engage with the limiting groove opened on the edge of the drawer plate, thereby locking the drawer plate.

[0027] Furthermore, a position sensor is installed at the feeding trough to detect whether the O-rings are being fed in place.

[0028] Furthermore, the lower outer ring of the threading needle is provided with a micro-ring groove, which is used to cooperate with the feeding groove to pre-fit the O-ring, so as to maintain the stability of the O-ring's position and posture before transferring it to the support platform.

[0029] Furthermore, the outer diameter of the assembly ring is smaller than the outer diameter of the upper section of the threading needle, so that the O-ring, which is stretched open by the ring support platform, can be fitted onto the assembly ring without obstruction.

[0030] Furthermore, the inner diameter of the countersunk hole is larger than the outer diameter of the cylindrical pressing end, and the countersunk hole covers the pressing end until it just blocks the upper annular groove and exposes the lower annular groove.

[0031] Furthermore, the front and rear side plates of the clamping platform are also provided with calibration holes that cooperate with the calibration guide pins to assist in the accurate positioning of the automatic ring threading, ring support, and ring pressing components with the ring support platform.

[0032] Furthermore, the assembly table is equipped with positioning sleeves on both the front and rear sides that cooperate with the calibration guide pins to accurately position the automatic O-ring threading, supporting, and pressing components, and to accurately complete the O-ring assembly.

[0033] The automatic O-ring threading, supporting, and pressing assembly threaded the O-rings supplied from the array on the material distribution table through the threading needle shaft hole. Then, the automatic transfer assembly transferred the O-rings to the supporting platform. The threading needle was pressed down, and the supporting platform pushed the O-rings up and down and gradually opened them up until the O-rings were transferred to the supporting cylinder. The supporting cylinder was then moved to the top of the pressing end of the button to which the O-rings were to be threaded. The supporting cylinder was then placed down to cover the pressing end until it blocked the upper annular groove and exposed the lower annular groove. Then, the peeling block peeled the O-rings down from the supporting cylinder until the O-rings were placed in the lower annular groove of the pressing end, completing the assembly of the O-rings.

[0034] The beneficial effects of the technical solution of this invention are:

[0035] 1. The automatic O-ring assembly equipment for the smart glasses button uses an automatic feeding, automatic placement, automatic picking, automatic transfer, automatic opening, automatic target positioning, and automatic O-ring pressing process to precisely fit the lower ring groove of the pressing end of the long strip button that fits the temple of the smart glasses onto the O-ring. This solves the problems of low O-ring installation efficiency, low O-ring installation process qualification rate, and high scrap rate caused by poor assembly of O-ring and pressing end, thus improving mass production efficiency and process qualification rate.

[0036] 2. Using the support ring platform, the O-ring pre-fitted below the threading needle is elastically compressed horizontally and relatively slid vertically. The O-ring is then pushed up along the threading needle until it crosses the assembly ring of the support ring cylinder, whose outer diameter is slightly smaller than that of the threading needle. The threading needle is then retracted axially along the support ring cylinder, releasing the O-ring onto the assembly ring. At this point, the O-ring has the positioning and assembly posture for fitting into the lower ring groove, providing a precise control basis for the fitting process.

[0037] 3. The inner depth of the countersunk hole of the support ring cylinder is made such that it can fit the pressing end and just block the upper ring groove while exposing the lower ring groove. This allows the O-ring to be directly installed without the interference of the upper ring groove, and directly reach the lower ring groove, thus greatly improving the assembly qualification rate.

[0038] 4. By setting bushings, calibration holes, and positioning sleeves on the material spreading table, clamping platform, and assembly table respectively, and ensuring that they are all precisely matched with the calibration rod sleeve, the positioning accuracy of the automatic ring threading, supporting, and pressing components and the O-rings, as well as the accuracy of the automatic ring threading, supporting, and pressing components and the pressing end of the button, are further improved.

[0039] 5. The button to be fitted with an O-ring is first positioned by the vertical pressing mechanism and the horizontal clamping mechanism, then pressed by the pressure arm, and then locked by the clamping plate on one side of the pressing end. Of course, the other side of the pressing end is pushed by the pressure bar of the push-pressing component. The button is locked on three sides, ensuring the accuracy, stability and reliability of the O-ring fitting process.

[0040] 6. The designed drawer mechanism facilitates material feeding to the vibratory feeder. The left and right clamping blocks have gaps larger than the size of the threading needle. The threading needle groove is equipped with a guide chamfer to facilitate precise positioning of the threading needle. The micro-ring groove is set on the outer ring of the lower end of the threading needle. These detailed designs all reflect the precise control of the O-ring opening and assembly process, which is highly practical and has a high degree of automation. Attached Figure Description

Detailed Implementation

[0060] The technical solution of the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. For ease of description, only the parts related to the present invention are shown in the drawings, not the entire structure.

[0061] In the description of this invention, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0062] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0063] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0064] Please see Figure 1 This embodiment proposes an automatic O-ring fitting device for smart glasses buttons, used to automatically, quickly and accurately fit O-rings 8 onto the elongated button 9 that is adapted to the temple of smart glasses. It includes an O-ring feeding component, an automatic transfer component 4 composed of X-axis and Z-axis electric cylinder slides, an automatic ring threading, supporting and pressing component 7 driven by the automatic transfer component 4, a supporting platform 3 for cooperating with the threading needle 703 to push the O-ring 8 onto the supporting cylinder 710, a positioning platform 6 for assembling the O-ring 8 onto the button 9, and a push and pressing component 5 for assisting in clamping the button 9.

[0065] Specifically, see Figure 2 , Figure 3 and Figure 4 The O-ring feeding assembly includes a vibratory plate 2 (which belongs to the prior art) equipped with a number of O-rings 8 and providing stable feeding, a material distribution plate 102, a material spreading table 103, and an auxiliary needle threading mechanism 1.

[0066] Further implementation plans are as follows, see [link / reference] Figure 2 The discharge port of the vibratory plate 2 is connected to the distribution plate 102, and a feeding cover 101 is provided at the upper end. There are four feeding slides evenly distributed in the distribution plate 102. The ends of all the feeding slides end at the four feeding slots of the spreading platform 103. The O-rings 8 that are vibrated and fed are stably and evenly fed to the spreading platform 103 along the feeding slides.

[0067] Specifically, see Figure 3The material feeding platform 103 has four O-rings 8 feeding slots arranged in an array. On both sides of the feeding slots are bushings 1031 to facilitate the precise insertion and positioning of the calibration guide pins 702. An auxiliary needle threading mechanism 1 is also provided on one side of the four feeding slots.

[0068] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 2 The auxiliary needle-threading mechanism 1 includes an auxiliary needle-threading cylinder 105, a needle-threading plate 104, and a linear guide rail. The auxiliary needle-threading cylinder 105 drives the needle-threading plate 104 to move back and forth. The needle-threading plate 104 has needle slots 1041, the same number as the number of the feeding slots, on one side edge facing the feeding slot. (See reference...) Figure 3 The needle groove 1041 is provided with a guide chamfer to facilitate the precise positioning of the threading needle 703. The threading needle 703 is guided into the O-ring 8 in the feeding groove and pressed down, so that the O-ring 8 can be placed on the outer ring of the threading needle 703.

[0069] Preferred options, please refer to Figure 3 A position sensor 109 is installed at the feeding trough to detect whether the O-ring 8 is in place.

[0070] The automatic transfer component 4 uses an electric cylinder slide table to control the automatic ring threading, ring support, and ring pressing component 7 to move between the O-ring feeding component, the ring support platform 3, and the positioning platform 6, driving the O-ring 8 to complete the four process steps of picking up, opening, positioning, and fitting in sequence.

[0071] Further implementation plans are as follows, see [link / reference] Figure 10 , Figure 11 and Figure 12 The automatic ring threading, ring support, and ring pressing assembly 7 includes an assembly frame 701, a calibration guide pin 702, a ring threading needle 703, a ring support cylinder 710, a ring peeling block 709, a needle-pulling cylinder 706 that retracts the ring threading needle 703, a stripping cylinder 707 that peels off the O-ring 8 from the ring peeling block 709, a linear guide rail, and a connecting arm 708.

[0072] Specifically, see Figure 13 ,and Figure 14 The upper section of the threading needle 703 is cylindrical, and the lower section is conical. Four keyways are arranged in a circular array on the outer ring of the upper section, and these keyways are clearance-fitted with the four keyway holes 7103 on the inner ring of the support ring cylinder 710. (See reference...) Figure 12 The needle-pulling cylinder 706 drives the threading needle 703 to freely extend and slide along the axial direction of the support cylinder 710 through the connecting plate 705. The lower section of the threading needle 703 is used to open the inner hole of the O-ring 8.

[0073] Preferably, the lower outer ring of the threading needle 703 is provided with a micro-ring groove. The micro-ring groove is used to cooperate with the feeding trough to pre-fit the O-ring 8, so as to maintain the stability of the position and posture of the O-ring 8 before transferring it to the support ring platform 3, and to accurately control the material flow.

[0074] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 14 and Figure 15 The outer ring of the support ring cylinder 710 is positioned by the limiting plate 704 set by the assembly frame 701 to ensure its positioning accuracy. The lower part of the support ring cylinder 710 is provided with a stepped frustum, which divides the outer ring of the support ring cylinder 710 into an assembly ring 7101 for receiving the opened O-ring 8. The inner ring of the assembly ring 7101 is also provided with a countersunk hole 7102 for fitting the pressing end 901.

[0075] A crucial implementation method is that the inner diameter of the countersunk hole 7102 is larger than the outer diameter of the cylindrical pressing end 901, and the countersunk hole 7102 fits over the pressing end 901 until it just blocks the upper annular groove 902 and exposes the lower annular groove 903. This allows the O-ring 8 to directly avoid the interference of the upper annular groove 902 and reach the lower annular groove 903 during the downward fitting process, greatly improving the assembly qualification rate.

[0076] Equally important, see Figure 13 and Figure 15 The outer diameter of the assembly ring 7101 is smaller than the outer diameter of the upper section of the threading needle 703, so that the O-ring 8, which is supported by the ring support platform 3, can be fitted onto the assembly ring 7101 without obstruction. After the threading needle 703 retracts upward, the O-ring 8 releases its deformation force, contracts and stays on the outer periphery of the assembly ring 7101.

[0077] See Figure 10 and Figure 11 The assembly frame 701 is used to position the push plate 502, the needle-pulling cylinder 706, the stripping cylinder 707, the linear guide rail, and the calibration guide pin 702.

[0078] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 11 The stripping cylinder 707 drives the connecting arm 708, which is defined by a linear guide rail, to extend and retract. The connecting arm 708 is connected to the stripping ring block 709. (See reference...) Figure 13 The stripping block 709 is provided with a stripping hole 7091 that is clearance-fitted with the shaft hole of the assembly ring 7101 of the support ring cylinder 710. Under the push of the stripping cylinder 707, the stripping block 709 pushes the O-ring 8 received by the assembly ring 7101 downward to peel it off, thereby realizing the assembly of the O-ring 8 and the pressing end 901.

[0079] See Figure 5 and Figure 6The support platform 3 includes a clamping platform 301, a linear slide rail, two sets of opposing clamping blocks and clamping springs. The clamping blocks are sleeved on the linear slide rail and pushed linearly by the clamping springs. The clamping blocks are arranged symmetrically to push each other, including a left clamping block 303 and a right clamping block 302. A gap 305 larger than the lower diameter of the threading needle 703 is left between the left and right clamping blocks to facilitate the smooth downward pressing of the threading needle 703 and the upward lifting of the O-ring 8 along the threading needle 703 by the clamping blocks, so that it can smoothly reach the assembly ring 7101.

[0080] Preferably, the front and rear side plates 304 of the clamping platform 301 are also provided with calibration holes 3041 that cooperate with the calibration guide pin 702 to assist the automatic ring threading, ring support, and ring pressing assembly 7 in accurately positioning the ring support platform 3.

[0081] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 7 and Figure 8 The positioning platform 6 includes a support platform 601, an assembly platform 606, a vertical pressing mechanism for positioning the button 9, and a horizontal clamping mechanism.

[0082] Specifically, the assembly table 606 is used to assemble the O-ring 8 on the button 9. It has a built-in support block for positioning the O-ring 8 to be assembled, and is positioned and limited by a stop block 607 on one side. The support block is designed to conform to the bottom contour of the button 9 and is pushed upward by a support spring.

[0083] A further embodiment is that the vertical pressing mechanism includes a pressing cylinder 609, a cam block 608, a lifting frame 613 controlled by a guide rod and guide sleeve assembly, a sliding seat 602, and four pressing arms 605 connected to the lifting frame 613. The pressing cylinder 609 drives the cam block 608 to move horizontally. The upper surface of the cam block 608 is provided with an involute pushing surface. The pushing surface cooperates with the rollers 612 designed below the lifting frame 613 to drive the lifting frame 613 to move up and down. Guide rods 614 and return springs 611 are symmetrically arranged on both sides of the lifting frame 613. Guide sleeves 610 are arranged on both sides of the sliding seat 602 to limit the lifting frame 613 to only move up and down. See reference. Figure 9 The pressure arm 605 presses and locks the button 9 of the O-ring 8 to be fitted, and the sliding seat 602 cooperates with the horizontal clamping mechanism to achieve horizontal movement.

[0084] Further implementation plans are as follows, see [link / reference] Figure 8 The horizontal clamping mechanism includes a clamping cylinder 603, a clamping plate 604, and a slider rail assembly that limits the horizontal linear sliding of the sliding seat 602. The clamping cylinder 603 drives the clamping plate 604 to push linearly. The front end face of the clamping plate 604 is provided with a positioning groove that fits the pressing end 901 of the O-ring 8 to be installed, thereby positioning the end face of the pressing end 901.

[0085] Further implementation plans are as follows, see [link / reference] Figure 7 The sliding seat 602 is also connected to the clamping plate 604. The clamping cylinder 603 drives the sliding seat 602, which in turn drives the lifting frame 613 to move horizontally, thereby controlling the pressure arm 605 to move horizontally to make room for the button 9.

[0086] Preferably, the assembly table 606 is also provided with positioning sleeves 6061 on the front and rear sides to cooperate with the calibration guide pins 702, so as to accurately position the automatic ring threading, ring supporting and ring pressing assembly 7 and accurately complete the assembly of O-rings 8.

[0087] As a further technical solution of this embodiment, see [link to relevant documentation]. Figure 6 The push-pressing assembly 5 is positioned in alignment with the clamping plate 604 and includes a push plate 502 controlled by a linear guide rail, a pressure bar 505, a booster spring 504 for pushing the pressure bar 505, a stop bar 503, and a push cylinder 501 for pushing and pulling the push plate 502. The push cylinder 501 drives the push plate 502 to slide towards the pressing end 901 of the button 9 that is to be fitted with an O-ring 8, and the push end faces 5051 of the four pressure bars 505 embedded in the push plate 502 are opposite to the other end face of the pressing end 901, clamping the pressing end 901 relative to the clamping plate 604. At this point, the button 9 to be fitted with the O-ring 8 is first positioned by the vertical pressing mechanism and the horizontal clamping mechanism, then pressed by the pressure arm 605, and then locked by the clamping plate 604 on one side of the pressing end 901. Of course, the other side of the pressing end 901 is pushed by the pressure bar 505 of the push-pressing component 5, thus locking the button 9 on three sides, ensuring the accuracy, stability and reliability of the ring fitting process.

[0088] The working principle of this embodiment is as follows: The O-rings 8 supplied in the array on the material spreading table 103 are threaded through the shaft hole of the threading needle 703 using the automatic threading, supporting and pressing component 7. Then, the O-rings 8 are transferred to the supporting platform 3 by the automatic transfer component 4. The threading needle 703 is pressed down, and the supporting platform 3 pushes the O-rings 8 up and down and gradually opens them up until the O-rings 8 are transferred to the supporting cylinder 710. The supporting cylinder 710 is then transferred to the pressing end 901 of the button 9 that is to be threaded with the O-rings 8. The supporting cylinder 710 is placed down to cover the pressing end 901 until it blocks the upper ring groove 902 and exposes the lower ring groove 903. Then, the peeling block 709 peels the O-rings 8 down from the supporting cylinder 710 until the O-rings 8 are placed in the lower ring groove 903 of the pressing end 901, thus completing the assembly of the O-rings 8.

[0089] As an extension of the technical solution of this embodiment, the vibratory feeder 2 is controlled by a drawer mechanism to realize docking and separation with the material distribution plate 102, which facilitates the filling of O-rings 8 into the vibratory feeder 2. The drawer mechanism includes a drawer plate 106, a drawer slide rail assembly 108, a locking cylinder 107 and a locking pin. The locking cylinder 107 drives the locking pin to engage with the limiting groove opened on the edge of the drawer plate 106, thereby locking the drawer plate 106.
