Description

Technical Field

[0001] This invention relates to the field of gasket conveying technology, specifically to a gasket conveying system and conveying method. Background Technology

[0002] A gasket is a sealing component typically used to fill the gap between two mating surfaces to prevent fluid leakage. Its function is to allow two workpieces to join together without leakage, even under compressive forces. Gaskets can fill in some irregular parts on the surface, thus allowing slight defects on the mating surfaces of the workpieces. Typically, gaskets are made of sheet materials such as gasket paper, rubber, silicone rubber, metal, cork, felt, etc. There are many types and materials of gaskets, including non-metallic gaskets, metallic gaskets, and metal-non-metallic composite gaskets.

[0003] A Chinese patent with patent number CN115504194B has been granted a glass gasket conveying device. This device includes a sieving device and a conveying device located at the outlet of the sieving device. The sieving device is supported above the glass machine and has a suction / blowing section at its outlet. Material from the sieving device's outlet is conveyed to the conveying device via the suction / blowing section. The conveying device's outlet is equipped with a distributing device that moves the material to a fixed position on the glass surface. Each conveying device corresponds to one distributing device. The glass gasket conveying device also includes a pushing device, located on the sieving device, to push the material within the sieving device to its outlet. This invention's glass gasket conveying device, by incorporating a sieving device and a suction / blowing section, conveys individually separated material to the conveying device and uses distributing devices to move the material to fixed positions on the glass. This allows for effective material separation and accurate positioning, improving the production efficiency of vacuum glass manufacturing.

[0004] In existing gasket conveying systems, when gaskets are stacked on pillars or other supporting structures for subsequent storage, management, or use, the diameter of the pillar or supporting structure is smaller than the diameter of the center hole of the gasket. When the gasket is placed on the pillar, it may get stuck on the supporting structure due to tilting. This is especially true for lighter gaskets, which are difficult to fall off under their own weight, thus affecting the stacking efficiency of the gaskets. Therefore, a gasket conveying system and conveying method are proposed. Summary of the Invention

[0005] The purpose of this invention is to provide a gasket conveying system and conveying method, which has the advantage of effectively preventing gaskets from getting stuck on the guide column due to deflection or tilting, and solves the problem of gaskets getting stuck on the support structure, thus affecting the gasket stacking efficiency.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gasket conveying system, comprising a substrate for placing circular gaskets and a worktable for supporting the substrate, wherein the circular gasket includes an integrally formed central hole in the middle, and the substrate is provided with a conveying structure for stacking and arranging circular gaskets.

[0007] The material conveying structure includes a material groove formed on the substrate for accommodating circular pads, and a material feeding assembly for supplying circular pads into the material groove is provided above the substrate.

[0008] A bottom support is fixedly connected to the bottom of the substrate, and a guide post is detachably connected to the upper surface of the bottom support.

[0012] Preferably, a U-shaped support is fixedly connected to the substrate at the position corresponding to the material chute, and the end of the open feed cylinder away from the ring frame is fixedly connected to the U-shaped support.

[0013] Preferably, the transverse component includes an I-shaped slide bar that reciprocates in the horizontal direction, and a transverse sliding groove is provided on the base plate for the I-shaped slide bar to slide horizontally. The I-shaped slide bar is positioned corresponding to a circular pad on the sliding groove.

[0014] The substrate is provided with a clearance component for receiving a circular pad at one end facing the guide post.

[0015] Preferably, the clearance component includes two sets of end swing blocks that rotate on a fixed axis at the end of the substrate, and a groove opened between the two sets of end swing blocks corresponding to the position of the sliding groove forms a material placement groove for receiving the circular pad.

[0016] Both sets of end swing blocks deflect in the vertical direction around the central axis of the material chute.

[0017] Preferably, one side of the directional disk is provided with a pendulum circle that rotates on the base plate with a fixed axis. A triangular cone plate and an oblique adjustment rod are fixedly connected to the outer circumference of the pendulum circle. A first adjustment pin and a second adjustment pin are fixedly connected to the directional disk corresponding to the position of the triangular cone plate.

[0018] A positioning pin is fixedly connected to the I-shaped slide rod, and a positioning groove is provided on the inclined adjustment rod for the positioning pin to slide. A stop rod is also fixedly connected to the side of the I-shaped slide rod facing the directional disc.

[0019] Preferably, the sleeve-moving assembly includes a connecting column that moves freely in the vertical direction. The connecting column has a receiving groove facing the material feeding groove. An inner top cavity is formed inside the connecting column. The connecting column also has a vertical column cavity for receiving the guide column. The two ends of the vertical column cavity are respectively connected to the receiving groove and the inner top cavity. The connecting column has multiple sets of air guide grooves that are distributed in a ring and are equidistant. The two ends of the air guide grooves are respectively connected to the receiving groove and the inner top cavity.

[0020] The sleeve displacement assembly also includes an air cylinder fixedly connected to the base plate. The air cylinder and the inner top cavity are connected in gas communication. A piston column that can move freely in the horizontal direction is provided inside the air cylinder. The piston column is fixedly connected to the I-shaped slide rod. A piston plate is fixedly connected to the end of the piston column away from the I-shaped slide rod. The outer peripheral surface of the piston plate is in sliding contact with the inner wall of the air cylinder.

[0021] Preferably, the vertical column cavity is provided with an upper ring seat and a lower ring seat, the outer peripheral surfaces of both the upper ring seat and the lower ring seat are in sliding contact with the side wall of the vertical column cavity, and the vertical column cavity is also provided with a vertical connecting column, the two ends of which are fixedly connected to the upper ring seat and the lower ring seat respectively.

[0022] The connecting column is fixedly connected to the vertical column cavity position with a limiting ring, and a return spring is sleeved on the outer circumferential surface of the vertical connecting column. The two ends of the return spring are fixedly connected to the limiting ring and the upper ring seat, respectively.

[0023] Preferably, the substrate is provided with a vertical link that moves freely in the vertical direction, and a horizontal link is fixedly connected to the top of the vertical link, and the end of the horizontal link away from the vertical link is fixedly connected to the connecting post.

[0024] The bottom of the vertical connecting rod is fixedly connected to an inclined rod, and a side rod is fixedly connected to the I-shaped sliding rod. A corresponding pin is fixedly connected to the side rod facing the inclined rod, and a corresponding groove is provided on the inclined rod for the corresponding pin to slide.

[0025] Preferably, a gasket conveying method, applied to a gasket conveying system, includes the following steps:

[0026] S1. Gasket guidance: First, the processed circular gasket is placed at the starting position of the conveying system. Once the circular gasket is placed in the ring frame, the feeding component drives the single set of circular gaskets in the ring frame to fall into the sliding chute.

[0027] S2, Gasket Lateral Movement: Driven by the lateral movement component, the circular gasket located at the material chute moves to the end swing block, thereby making the circular gasket and the guide column correspond to each other in the vertical direction.

[0028] S3, Adsorption and downward movement: The connecting column is driven by the sleeve displacement component to adsorb the circular pad at the end swing block under negative pressure, and the circular pad moves in the direction of the guide column, so that the circular pad is sleeved on the guide column.

[0029] S4, Reaction Force Falling: The connecting column moves upward, and by changing the air pressure difference, it applies a downward force to the circular gasket sleeved on the guide column to prevent the circular gasket from getting stuck on the guide column due to tilting;

[0030] S5. Repeated conveying: Repeat steps S1-S4 to complete the conveying process of multiple sets of circular pads in the ring frame, so that they can be set on the guide column one by one.

[0031] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0032] This invention achieves automated conveying of circular pads through the negative pressure adsorption function of the sleeve displacement component and the connecting column, thereby saving labor costs, improving conveying stability and efficiency. At the same time, it can apply a reaction force to the circular pads, effectively preventing the pads from getting stuck on the guide column due to deflection or tilting, thus ensuring that the pads can fall smoothly and continue to be conveyed.

[0033] This invention, through the cooperation of the feeding component and the transverse component, can ensure the accurate guidance and positioning of the circular gaskets during the conveying process. This helps to improve the accuracy and stability of gasket conveying and enables the continuous conveying of multiple sets of gaskets, thereby improving conveying efficiency.

Detailed Implementation

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0047] Please see Figures 1 to 11 The present invention provides a technical solution: a pad conveying system, including a base plate 1 for placing circular pads 22 and a worktable for supporting the base plate 1. The circular pads 22 include an integrally formed central hole 221 in the middle. The base plate 1 is provided with a conveying structure for stacking and placing the circular pads 22.

[0048] The material conveying structure includes a material groove 18 formed on the substrate 1 for accommodating a circular pad 22, and a material feeding assembly for supplying the circular pad 22 into the material groove 18 is provided above the substrate 1.

[0049] A bottom support 38 is fixedly connected to the bottom of the substrate 1. A guide post 39 is detachably connected to the upper surface of the bottom support 38. A transverse component is provided on the substrate 1 to push a single set of circular pads 22 placed on the sliding groove 18 to the top of the guide post 39.

[0050] Above the transverse component is a sleeve-moving component that adsorbs and fixes the circular pad 22 located above the guide post 39 and sleeves it on the guide post 39.

[0051] like Figure 1 and Figure 2 As shown, when the circular pads 22 are stacked on the guide post 39, the feeding assembly causes a single set of circular pads 22 to fall into the sliding groove 18. The substrate 1 is provided with a lateral moving assembly that pushes the circular pads 22 on the sliding groove 18. The circular pads 22 on the sliding groove 18 are moved horizontally by the lateral moving assembly to directly above the guide post 39, thereby completing the horizontal movement process of the circular pads 22.

[0052] At the same time, the circular pad 22 above the guide post 39 is driven downward by the sleeve displacement assembly. Even if the circular pad 22 moves towards the guide post 39 and is eventually sleeved on it, the sleeve displacement assembly can adsorb and fix the circular pad 22 when it moves downward to prevent the circular pad 22 from falling off or deflecting excessively during the movement, thereby ensuring that the position of the central hole 221 in the circular pad 22 corresponds to the guide post 39.

[0053] It should be noted that in actual use, the diameter of the guide post 39 needs to be compatible with the size of the center hole 221 of the circular pad 22 being conveyed. Specifically, the diameter of the guide post 39 needs to be smaller than the size of the center hole 221 to ensure that the circular pad 22 can be smoothly fitted onto the guide post 39. At the same time, the guide post 39 is fixed to the bottom support 38 with bolts to facilitate the replacement of the guide post 39.

[0054] In one preferred embodiment, the feeding assembly includes an orientation disk 3 that rotates freely in the horizontal direction and is fixedly rotated on a substrate 1. A ring frame 2 is fixedly connected to the substrate 1. A vertical shaft 13 is fixedly rotated at the center of the ring frame 2. The vertical shaft 13 is coaxially fixed with the orientation disk 3.

[0055] Multiple sets of equidistant side rods 14 are fixedly connected to the outer circumference of the vertical shaft 13. Each set of side rods 14 is fixedly connected to a hard brush 15 on one side facing the ring frame 2. An open feed cylinder 16 is fixedly connected through the ring frame 2 at the position corresponding to the material chute 18.

[0056] The substrate 1 is fixedly connected to the U-shaped support seat 17 at the position corresponding to the sliding groove 18, and the end of the open feed cylinder 16 away from the ring frame 2 is fixedly connected to the U-shaped support seat 17.

[0057] like Figure 2 , Figure 3 and Figure 9 As shown, a motor fixed on the substrate 1 drives the directional disk 3 to rotate freely in the horizontal direction, thereby driving the vertical shaft 13, which is coaxially fixed with the directional disk 3, to rotate synchronously. Multiple sets of hard brushes 15 are fixedly connected to the vertical shaft 13 via side rods 14. The horizontal rotation of the side rods 14 and the hard brushes 15 pushes the randomly placed circular pads 22 in the ring frame 2, so that the circular pads 22 can fall into the open feed cylinder 16 during the pushing process. The outlet end of the open feed cylinder 16 corresponds to the position of the sliding groove 18, thereby moving the circular pads 22 in the ring frame 2 into the sliding groove 18.

[0058] It should be noted that the multiple sets of side rods 14 and hard brushes 15 divide the internal space of the ring frame 2 into multiple fan-shaped areas with the same spatial size. In actual use, the number of circular pads 22 in the ring frame 2 may be inconsistent due to random placement. However, since the circular pads 22 are pushed by the hard brushes 15 on the side rods 14, when there are too many circular pads 22 in a certain area, some of the circular pads 22 in that area may be placed in adjacent fan-shaped areas as the side rods 14 rotate. Therefore, the number of circular pads 22 in multiple fan-shaped areas can be made relatively consistent.

[0059] Meanwhile, since the diameter of the connection between the open feed cylinder 16 and the ring frame 2 is larger than the diameter of the circular pad 22, the circular pad 22 may be slightly deflected when it falls into the open feed cylinder 16. However, as the hard brush 15 continues to rotate, it can sweep the circular pad 22 that initially enters the open feed cylinder 16, ensuring that the circular pad can fall smoothly onto the sliding trough 18. The open feed cylinder 16 has a certain height, which can store multiple circular pads 22 to ensure the continuous operation of the pad conveying system. At the same time, the distance between the U-shaped support 17 and the sliding trough 18 is greater than the thickness of a single circular pad 22 but less than the thickness of two circular pads 22, ensuring that only one circular pad 22 falls onto the sliding trough 18 each time.

[0060] Based on the feeding assembly embodiment, the transverse component includes an I-shaped slide bar 12 that reciprocates in the horizontal direction. A transverse sliding groove 19 is provided on the substrate 1 for the I-shaped slide bar 12 to slide horizontally. The I-shaped slide bar 12 corresponds to the circular pad 22 located on the material sliding groove 18. A relief component for receiving the circular pad 22 is provided at one end of the substrate 1 facing the guide column 39.

[0061] The clearance component includes two sets of end swing blocks 20 that rotate at the end of the substrate 1. The grooves between the two sets of end swing blocks 20, corresponding to the position of the sliding groove 18, form a material placement groove 21 for receiving the circular pad 22. Both sets of end swing blocks 20 deflect in the vertical direction with the central axis of the sliding groove 18 as the center.

[0062] like Figure 1 , Figure 3 and Figure 5 As shown, the I-shaped slide bar 12, which moves freely in the horizontal direction, drives the circular pad 22 on the sliding groove 18 to move toward the two sets of end swing blocks 20 until the circular pad 22 abuts against the two sets of end swing blocks 20. At this time, the circular pad 22 is on the material placement groove 21 and corresponds to the position of the guide column 39 below.

[0063] Meanwhile, when the sleeve-shifting assembly is running, it can adsorb the circular pad 22 located in the material trough 21 and drive the adsorbed circular pad 22 to move downward. At this time, as the sleeve-shifting assembly runs, the two sets of end swing blocks 20 will deflect in the vertical direction. The purpose is to provide room for the downward movement of the sleeve-shifting assembly through their own deflection, so as to avoid the existence of the end swing blocks 20 interfering with the operation of the sleeve-shifting assembly.

[0064] Among them, a torsion spring is provided between the end swing block 20 and the substrate 1 to drive the end swing block 20 to return to the initial position. The torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure. It should be noted that the end swing block 20 is initially in a horizontal state, which can support the circular pad 22 that has moved to this position, so as to ensure that the position of the circular pad 22 corresponds to the position of the guide column 39 in the vertical direction.

[0065] Based on the transverse component embodiment, the directional disk 3 is provided with a swing circle 4 that rotates on the base plate 1 on a fixed axis on one side. A triangular cone plate 7 and an oblique adjustment rod 8 are fixedly connected to the outer circumferential surface of the swing circle 4. A first adjustment pin 5 and a second adjustment pin 6 are fixedly connected to the directional disk 3 at the position corresponding to the position of the triangular cone plate 7.

[0066] A positioning pin 9 is fixedly connected to the I-shaped slide rod 12, and a positioning groove 10 is provided on the inclined adjustment rod 8 for the positioning pin 9 to slide. A stop rod 11 is also fixedly connected to the side of the I-shaped slide rod 12 facing the directional disc 3.

[0067] like Figure 2 , Figure 4 and Figure 8As shown, when the directional disc 3 rotates in the horizontal direction, it can drive the first adjusting pin 5 and the second adjusting pin 6 fixed on it to rotate synchronously in the horizontal direction. When the first adjusting pin 5 or the second adjusting pin 6 contacts the stop rod 11, it can drive the I-shaped slide rod 12 fixedly connected to the stop rod 11 to move towards the end swing block 20 through the stop rod 11.

[0068] Meanwhile, when the first adjusting pin 5 or the second adjusting pin 6 contacts the triangular cone plate 7, it can drive the pendulum circle 4 and the inclined adjusting rod 8 fixed thereon to swing by pushing the triangular cone plate 7. The positioning pin 9 fixed on the I-shaped slide rod 12 is slidably connected to the inclined adjusting rod 8 through the positioning groove 10. Therefore, when the inclined adjusting rod 8 swings, it can drive the positioning pin 9 and the I-shaped slide rod 12 to move away from the end pendulum block 20 in the horizontal direction. Then, through the reciprocating motion of the I-shaped slide rod 12 in the horizontal direction, it drives the circular pad 22 on the sliding groove 18 to move horizontally to the position of the material placement groove 21.

[0069] Furthermore, the sleeve displacement assembly includes a connecting column 23 that moves freely in the vertical direction. The connecting column 23 has a receiving groove 26 facing the material placement groove 21. An inner top cavity 24 is formed inside the connecting column 23. The connecting column 23 also has a vertical column cavity 25 for receiving the guide column 39. The two ends of the vertical column cavity 25 are respectively connected to the receiving groove 26 and the inner top cavity 24. The connecting column 23 has multiple sets of air guide grooves 27 arranged in a ring and at equal intervals. The two ends of the air guide grooves 27 are respectively connected to the receiving groove 26 and the inner top cavity 24.

[0070] The sleeve displacement assembly also includes an air cylinder 42 fixedly connected to the base plate 1. The air cylinder 42 and the inner top cavity 24 are in gas communication. The air cylinder 42 is provided with a piston column 40 that can move freely in the horizontal direction. The piston column 40 is fixedly connected to the I-shaped slide rod 12. A piston plate 41 is fixedly connected to the end of the piston column 40 away from the I-shaped slide rod 12. The outer peripheral surface of the piston plate 41 slides in contact with the inner wall of the air cylinder 42.

[0071] like Figure 1 , Figure 7 and Figure 10 As shown, when the connecting column 23 moves downward in the vertical direction, the distance between the circular gasket 22 at the material placement groove 21 and the receiving groove 26 decreases and eventually enters the receiving groove 26. It should be noted that during the downward movement of the connecting column 23, the piston plate 41 can move horizontally inside the air cylinder 42, and the air cylinder 42 is connected to the gas in the inner top cavity 24. Therefore, at this time, a negative pressure will be generated in the inner top cavity 24 as the piston plate 41 moves horizontally.

[0072] Meanwhile, when the circular pad 22 is in the receiving groove 26, the circular pad 22 can block the bottom of the air guide groove 27. At this time, as the connecting column 23 continues to move downward, the end swing block 20 is squeezed and deflected. However, when the end swing block 20 initially deflects, it can still support the circular pad 22 on it. At this time, as the piston plate 41 continues to move horizontally in the air cylinder 42, the inner top cavity 24 and the air guide groove 27 present a negative pressure phenomenon and attract the circular pad 22. Therefore, when the end swing block 20 continues to deflect and no longer contacts the circular pad 22, the circular pad 22 will not fall off under its own gravity, but will move downward synchronously with the connecting column 23.

[0073] It should be noted that the connecting column 23 is also provided with a micro-diameter hole that allows the inner top cavity 24 to communicate with the outside natural gas. When the piston plate 41 moves in the air cylinder 42, the inner top cavity 24 can alleviate the internal negative pressure phenomenon through the micro-diameter hole. However, negative pressure will still be generated at the air guide groove 27, which will adsorb and fix the circular gasket 22 of the column.

[0074] Based on the sleeve displacement assembly embodiment, the vertical column cavity 25 is provided with an upper ring seat 29 and a lower ring seat 30. The outer peripheral surfaces of both the upper ring seat 29 and the lower ring seat 30 are in sliding contact with the side wall of the vertical column cavity 25. The vertical column cavity 25 is also provided with a vertical connecting column 28, and the two ends of the vertical connecting column 28 are respectively fixedly connected to the upper ring seat 29 and the lower ring seat 30.

[0075] The connecting column 23 is fixedly connected to the vertical column cavity 25 with a limiting ring 31. The outer circumferential surface of the vertical connecting column 28 is fitted with a return spring 32, and the two ends of the return spring 32 are fixedly connected to the limiting ring 31 and the upper ring seat 29, respectively.

[0076] like Figure 1 , Figure 7 and Figure 10 As shown, as the connecting column 23 continues to move downward, the guide column 39 gradually enters the vertical column cavity 25. At this time, the circular gasket 22 is already fitted into the guide column 39. When the guide column 39 contacts and squeezes the lower ring seat 30, it will drive the upper ring seat 29 to move upward in the vertical column cavity 25 through the lower ring seat 30 and the vertical connecting column 28. During this process, the gas in the vertical column cavity 25 will be discharged into the inner top cavity 24, thereby alleviating the negative pressure phenomenon therein. After the circular gasket 22 is fitted onto the guide column 39, the air guide groove 27 will no longer generate negative pressure suction on the circular gasket 22 or reduce the negative pressure suction on the circular gasket 22.

[0077] At the same time, when the connecting column 23 moves upward, the piston plate 41 moves in the opposite direction inside the air cylinder 42. At this time, the gas inside the air cylinder 42 is blown towards the circular pad 22 through the inner top cavity 24 and the air guide groove 27 to prevent the circular pad 22 from getting stuck on the guide column 39 due to tilting. The gas blown out through the air guide groove 27 applies a downward force to the circular pad 22 to ensure that the circular pad 22 can fall naturally.

[0078] It should be noted that, in the initial state, the horizontal height of the connecting column 23 is higher than the horizontal height of the end swing block 20. When the material conveying structure is initially running, the I-shaped slide bar 12 pushes the circular pad 22 toward the end swing block 20. At this time, the connecting column 23 will move upward a certain distance until the I-shaped slide bar 12 moves away from the end swing block 20. Only then will the connecting column 23 move toward the end swing block 20 in the vertical direction. This can avoid the presence of the I-shaped slide bar 12 interfering with the vertical movement of the connecting column 23.

[0079] Furthermore, the substrate 1 is provided with a vertical connecting rod 36 that moves freely in the vertical direction, and a horizontal connecting rod 37 is fixedly connected to the top of the vertical connecting rod 36. The end of the horizontal connecting rod 37 away from the vertical connecting rod 36 is fixedly connected to the connecting post 23.

[0080] The bottom of the vertical connecting rod 36 is fixedly connected to an inclined rod 35, and a side rod 33 is fixedly connected to the I-shaped slide rod 12. A corresponding pin 34 is fixedly connected to the side rod 33 facing the inclined rod 35. A corresponding groove 351 for the corresponding pin 34 to slide is provided on the inclined rod 35.

[0081] like Figure 1 , Figure 2 and Figure 6 As shown, when the I-shaped slide bar 12 reciprocates in the horizontal direction, it can drive the corresponding pin 34 to move synchronously in the horizontal direction through the side rod 33. The connecting column 23 is fixedly connected to the inclined rod 35 through the horizontal connecting rod 37 and the vertical connecting rod 36, and the corresponding pin 34 is slidably connected to the inclined rod 35 through the corresponding groove 351. Therefore, when the I-shaped slide bar 12 moves horizontally, it can drive the connecting column 23 to move in the vertical direction, and the vertical movement direction of the connecting column 23 is related to the horizontal direction of the I-shaped slide bar 12. That is, when the connecting column 23 moves horizontally away from the end swing block 20, the connecting column 23 can move vertically towards the guide column 39.

[0082] A method for conveying a gasket in a gasket conveying system includes the following steps:

[0083] S1. Gasket guidance: First, the processed circular gasket 22 is placed at the starting position of the conveying system. Even if the circular gasket 22 is placed in the ring frame 2, the feeding component drives the single set of circular gaskets 22 in the ring frame 2 to fall into the sliding chute 18. This step ensures the accurate positioning and guidance of the circular gasket 22 in the conveying system.

[0084] S2. Lateral movement of the pad: Driven by the lateral movement component, the circular pad 22 located at the sliding groove 18 is moved to the end swing block 20, thereby making the circular pad 22 and the guide post 39 correspond in the vertical direction. Through this step, the circular pad 22 and the guide post 39 correspond in the vertical direction, which provides a foundation for the smooth progress of subsequent steps.

[0085] S3, Adsorption and downward movement: The connecting column 23 is driven by the sleeve displacement component to adsorb the circular pad 22 located at the end swing block 20 with negative pressure, and the circular pad 22 is driven to move in the direction of the guide column 39, so that the circular pad 22 is sleeved on the guide column 39. This step ensures that the circular pad 22 can be accurately sleeved on the guide column 39 to avoid deflection or falling off during the conveying process;

[0086] S4, Reaction Force Falling: The connecting column 23 moves upward, and by changing the air pressure difference, it applies a downward force to the circular pad 22 sleeved on the guide column 39, preventing the circular pad 22 from being stuck on the guide column 39 due to tilting;

[0087] S5. Repeated conveying: Repeat steps S1-S4 to complete the conveying process of multiple sets of circular pads 22 in the ring frame 2, so that they can be set on the guide column 39 one by one.

[0088] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
