Description

Technical Field

[0001] This invention relates to the field of sealing ring assembly technology, and more specifically, to a dual-station sealing ring assembly production equipment. Background Technology

[0002] The assembly of sealing rings is the core link to ensure the sealing performance of equipment. The traditional process relies on the "pre-formed sealing rings + manual placement" mode, but it faces the dual challenges of efficiency and quality. With the increasing requirements for sealing reliability in industries such as new energy and semiconductors, automated assembly technology has become a key breakthrough direction.

[0003] The average time for manually placing a sealing ring is 3-5 seconds per piece, while automated equipment can reduce it to 0.5 seconds per piece. However, current automated equipment can only operate at a single station and can only adjust the sealing ring of one diameter at a time. Changing to different specifications of sealing rings and workpieces requires re-adjusting parameters, which is not flexible enough and will lead to an increase in overall production costs. Summary of the Invention

[0004] In view of the problems existing in the prior art, the purpose of this invention is to provide a dual-station sealing ring assembly production equipment to solve the problems in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution.

[0006] A dual-station sealing ring assembly production equipment includes a housing. Inside the housing are a controller, a peristaltic pump, two ring expanding mechanisms, two ring closing mechanisms, and two feeding vibrating screens. The peristaltic pump is connected to and drives the ring expanding mechanisms and the ring closing mechanisms via a hose. The two ring expanding mechanisms and the two ring closing mechanisms are symmetrically installed. The two feeding vibrating screens are located on both sides and feed materials to the two ring expanding mechanisms.

[0007] The expanding ring mechanism includes an electric clamp, a fixed frame, and a retaining ring clamp. The fixed frame has a material discharge trough communicating with the discharge channel of the feeding vibrating screen. The fixed frame also has a through hole communicating with the material discharge trough. A ring tube passes through the through hole. One end of the ring tube passes through the electric clamp and extends outward. The other end of the ring tube passes through the retaining ring clamp and the ring expanding mechanism facing upward through the through hole. The retaining ring clamp is installed on the side of the fixed frame facing the ring expanding mechanism. The retaining ring clamp is used to push the sealing ring to move when the ring tube slides.

[0008] The ring-ringing mechanism includes a linear hydraulic cylinder, a movable seat, a vertical cylinder, and a locking block. The linear hydraulic cylinder is connected to the output end of the peristaltic pump via a hose. The linear hydraulic cylinder is fixedly installed inside the machine housing and drives the movable seat to move linearly. The vertical cylinder is fixedly installed on the movable seat, and the movable end of the vertical cylinder drives the locking block to move vertically along the movable seat.

[0009] As a further description of the above technical solution: the electric clamp includes a fixed base and two semi-circular grippers. The fixed base is installed inside the housing, and the two semi-circular grippers are symmetrically installed on the fixed base and aligned with the through holes.

[0010] As a further description of the above technical solution: the end of the ferrule tube facing the fixed seat is a flared end, the inner diameter of the flared end of the ferrule tube matches the outer diameter of the workpiece, the other end of the ferrule tube facing the fixed seat is a narrow end, and a pulling block is fixedly connected to the narrow end of the ferrule tube.

[0011] As a further description of the above technical solution: the bottom of the card block is provided with a notch that matches the narrow end of the collar tube, and the inner diameter of the notch is smaller than the outer diameter of the pulling block.

[0012] As a further description of the above technical solution: the retaining ring clamp includes two side electric grippers, which are symmetrically arranged on both sides of the retaining ring tube. When the retaining ring tube is pushed to move towards the moving seat, the side electric grippers close and engage with the outside of the retaining ring tube to block the sealing ring, so that the sealing ring moves in the opposite direction to the running direction of the retaining ring tube.

[0013] As a further description of the above technical solution: the top of the machine casing is provided with two cover plates, which are located directly above the two feeding vibrating screens respectively, and the cover plates are provided with feeding ports.

[0014] As a further description of the above technical solution: an operation panel is provided on the outer side of the housing, and control buttons are provided on the operation panel.

[0015] As a further description of the above technical solution: the outer side of the housing is provided with two through holes for the sleeve tubes to pass through, the inner diameter of the through holes is larger than the outer diameter of the sleeve tubes, and the diameters of the two sleeve tubes are set to two specifications to adapt to rubber rings of different sizes.

[0016] Compared with the prior art, the advantages of this invention are:

[0017] (1) This solution significantly improves production efficiency through the dual-station parallel operation mode. Compared with traditional single-station equipment, it can complete twice the workload in the same time, meeting the large and high-quality demand for sealing parts in industries such as new energy and semiconductors. The controller can accurately coordinate the operation of each component, and the peristaltic pump provides stable power for the ring expansion mechanism and the ring fitting mechanism, ensuring the precise control of the ring expansion and ring fitting process, and further guaranteeing the quality and consistency of sealing ring assembly.

[0018] (2) This solution uses a dual-station design to enable two stations to operate independently at the same time. The two feeding vibrating screens feed different specifications of sealing rings to the expansion mechanisms on both sides. The two expansion mechanisms and the two ring-fitting mechanisms are symmetrically installed, which enables the equipment to assemble sealing rings for two different sizes of workpieces or workpieces of the same size at the same time. When it is necessary to replace sealing rings and workpieces of different specifications, there is no need to readjust the equipment parameters as a whole. Only local adjustments need to be made at the corresponding station, which greatly improves the flexibility of the equipment and effectively avoids production interruptions caused by frequent changes in specifications, thereby reducing the overall production cost.

[0027] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0028] To address the problem that current automated equipment can only operate at a single workstation and has low work efficiency, Implementation Example 1 is proposed:

[0029] Please see Figures 1-6In this invention, the dual-station sealing ring assembly production equipment includes a housing 1. Inside the housing 1 are installed a controller 2, a peristaltic pump 3, two ring expanding mechanisms 4, two ring attaching mechanisms 5, and two feeding vibrating screens 6. The peristaltic pump 3 is connected to and drives the ring expanding mechanisms 4 and the ring attaching mechanisms 5 through a hose. The two ring expanding mechanisms 4 and the two ring attaching mechanisms 5 are symmetrically installed. The two feeding vibrating screens 6 are located on both sides and feed materials to the two ring expanding mechanisms 4.

[0030] The ring expanding mechanism 4 includes an electric clamp 41, a fixed frame 42, and a retaining ring clamp 43. The fixed frame 42 has a material discharge trough 44 inside, which communicates with the discharge channel of the feeding vibrating screen 6. The fixed frame 42 also has a through hole 45 inside, which communicates with the material discharge trough 44. A ring tube 46 passes through the through hole 45. One end of the ring tube 46 passes through the electric clamp 41 and extends outward. The other end of the ring tube 46 passes through the retaining ring clamp 43 and the through hole 45 and faces upward toward the ring expanding mechanism 5. The retaining ring clamp 43 is installed on the side of the fixed frame 42 facing the ring expanding mechanism 5. The retaining ring clamp 43 is used to push the sealing ring to move when the ring tube 46 slides.

[0031] The ring-ringing mechanism 5 includes a linear hydraulic cylinder 51, a movable seat 52, a vertical cylinder 53, and a locking block 54. The linear hydraulic cylinder 51 is connected to the output end of the peristaltic pump 3 through a hose. The linear hydraulic cylinder 51 is fixedly installed inside the housing 1 and drives the movable seat 52 to move linearly. The vertical cylinder 53 is fixedly installed on the movable seat 52. The movable end of the vertical cylinder 53 drives the locking block 54 to move vertically along the movable seat 52.

[0032] As a further description of the above technical solution: the electric clamp 41 includes a fixed base 411 and two semi-circular grippers 412. The fixed base 411 is installed inside the housing 1, and the two semi-circular grippers 412 are symmetrically installed on the fixed base 411 and aligned with the through hole 45.

[0033] As a further description of the above technical solution: the end of the sleeve tube 46 facing the fixed seat 411 is a flared end, the inner diameter of the flared end of the sleeve tube 46 matches the outer diameter of the workpiece, the other end of the sleeve tube 46 facing the fixed seat 411 is a narrow end, and a pulling block 47 is fixedly connected to the narrow end of the sleeve tube 46.

[0034] As a further description of the above technical solution: the bottom of the locking block 54 is provided with a notch 541 that matches the narrow end of the collar tube 46, and the inner diameter of the notch 541 is smaller than the outer diameter of the pulling block 47.

[0035] As a further description of the above technical solution: the retaining ring clamp 43 includes two side electric grippers 431, which are symmetrically arranged on both sides of the retaining ring tube 46. When the retaining ring tube 46 is pushed to move towards the moving seat 52, the side electric grippers 431 close and engage with the outside of the retaining ring tube 46 to block the sealing ring, so that the sealing ring moves in the opposite direction to the running direction of the retaining ring tube 46.

[0036] As a further description of the above technical solution: the top of the casing 1 is provided with two cover 7, which are located directly above the two feeding vibrating screens 6 respectively, and the cover 7 is provided with a feeding port 8.

[0037] As a further description of the above technical solution: an operation panel 9 is provided on the outer side of the housing 1, and control buttons 10 are provided on the operation panel 9.

[0038] Furthermore, to address the issue that only one diameter of sealing ring can be adjusted at a time, and that changing to different specifications of sealing rings and workpieces requires re-adjusting parameters, resulting in insufficient flexibility, Example 2 is proposed:

[0039] In this invention, a peristaltic pump 3 is connected to and drives the expansion mechanism 4 and the ring-locking mechanism 5 through a hose. The two expansion mechanisms 4 and the two ring-locking mechanisms 5 are installed symmetrically. Two feeding vibrating screens 6 are located on both sides and feed materials to the two expansion mechanisms 4.

[0040] First, the peristaltic pump 3 is started to drive and control the linear hydraulic cylinder 51, which pushes the moving seat 52 to move linearly and contact the sleeve tube 46, causing it to slide inside the electric clamp 41 and extend its flared end out of the machine housing 1. At this time, the pulling block 47 at the narrow end of the sleeve tube 46 is misaligned with the vertical material drop chute 44. Then, the feeding vibrating screen 6 is started to feed the sealing rings. The sealing rings are neatly arranged, and one sealing ring falls into the material drop chute 44 at a time, causing the sealing ring to fall into the through hole 45. Then, the sleeve tube 46 is pushed to reset and slide, so that the narrow end of the sleeve tube 46 passes through the sealing ring. At this time, the sealing ring is fitted onto the sleeve tube 46. On the outside, as the sleeve tube 46 continues to be pushed, the retaining ring clamp 43 is activated, causing the two side electric grippers 431 to close on the outside of the sleeve tube 46. As the sleeve tube 46 moves, the side electric grippers 431 block the sealing ring, causing it to shift relative to the outside of the sleeve tube 46 until the sealing ring is successfully opened by the moving sleeve tube 46 and fitted onto the flared end. As the sealing ring is pushed, it passes through the through hole 45. At this time, the pulling block 47 at its narrow end contacts the moving seat 52. At this time, the vertical cylinder 53 is activated to push the locking block 54 down. The notch 541 is used in conjunction with the pulling block 47 to position the sleeve tube 46. At this time, the first sealing ring is loaded.

[0041] Then, the linear hydraulic cylinder 51 is activated again to push the moving seat 52 to move linearly and push the sleeve tube 46 to reset. At the same time, the semi-circular gripper 412 on the fixed seat 411 is opened, allowing the sealing ring on the outside to extend smoothly. Then, the semi-circular gripper 412 resets and closes, fitting against the outside of the sleeve tube 46. At this time, the operator holds the end of the workpiece and inserts it into the inside of the sleeve tube 46, pushing it back. The semi-circular gripper 412 blocks the exposed sealing ring, causing it to fall off and fit into the sealing groove of the workpiece, realizing semi-automatic sealing ring assembly. The two sleeve tubes 46 operate synchronously, thus realizing the advantages of the device having dual-station operation, which is more efficient, and manual assistance in assembly, which improves the assembly success rate.

[0042] Please see Figure 1 and Figure 2 The outer side of the housing 1 is provided with two through holes 11 for the sleeve tube 46 to pass through. The inner diameter of the through hole 11 is larger than the outer diameter of the sleeve tube 46. The diameters of the two sleeve tubes 46 are set to two specifications to adapt to rubber rings of different sizes.

[0043] In this invention, by using two sleeve tubes with a diameter of 46 to accommodate rubber rings of different sizes, it is possible to achieve simultaneous operation of workpieces of different sizes and to meet the one-time assembly of dual-size sealing rings for workpieces. This results in the device having better adaptability and flexibility, reducing debugging costs, and improving product applicability.

[0044] The above description is merely a preferred embodiment of the present invention; however, the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and its improved concepts, should be covered within the scope of protection of the present invention.
