Description

Technical Field

[0001] This invention relates to the field of sealing ring inspection technology, and in particular to a multi-station feeding sealing ring visual inspection device. Background Technology

[0002] Sealing rings (O-rings, sealing rings, etc.) are widely used in automobiles, machinery, hydraulic systems, and various precision equipment, playing a vital role in sealing, leak prevention, and vibration damping. With increasing production volume and quality requirements, visual inspection technology for sealing rings has gradually become a core method of industrial automation inspection. Visual inspection of sealing rings refers to the automated identification and analysis of sealing rings using industrial cameras and image processing algorithms to determine their size, shape, surface defects (such as cracks, bubbles, burrs, etc.), and the condition of their front and back sides.

[0003] Traditional sealing ring inspection equipment still relies on manual feeding or single-layer pallets, resulting in intermittent sealing ring supply and unstable handling, which affects the cycle time and stability of subsequent visual inspection. Existing pallets or sealing ring racks are usually fixed structures, which are difficult to adapt to sealing rings of different sizes and working conditions. They are prone to displacement or flipping, and frequent manual adjustments are required when changing models, resulting in low efficiency. Visual inspection is mostly a single-station operation, and the sorting and collection after inspection require manual assistance or semi-automatic machinery, making it difficult to form a true closed-loop process and hindering continuous production.

The limiting rods 022 are used to prevent the feeding pallet 1 from shaking. The limiting rods 022 on both sides are provided with discharge ports 0221 on the rods at the horizontal height of the worktable 01. The discharge ports 0221 facilitate the separation of the feeding pallet 1 from the feeding rack 03.

[0027] In addition, a slide rail connecting plate 032 is vertically installed on one side of the feeding rack 03. The slide rail connecting plate 032 is used to install on the sliding seat of the first electric slide rail 021. Multiple pallet support side plates 031 are evenly arranged on the feeding rack 03 along the vertical direction.

A pallet limiting block 033 is provided on the surface of the pallet support side plate 031 away from the workbench 01 to abut against the feeding pallet 1. The pallet limiting block 033 works with the limiting rod 022 to prevent the feeding pallet 1 from shaking on the feeding rack 03.

[0028] The feeding pallet 1 has multiple placement slots 12 evenly arranged on it for placing the sealing ring frame 2. Magnetic suction slots 121 are symmetrically arranged on the bottom wall of the placement slots 12. Handles 11 are vertically and symmetrically arranged on the side of the feeding pallet 1 away from the worktable 01.

[0029] Meanwhile, the top frame of the sealing ring frame 2 is symmetrically provided with second slots 23 for being clamped by the feeding unit 05. The slide rods on the slide rod frame 22 are all fitted with first springs 24 for resisting the limiting mechanism 4. The bottom of the sealing ring frame 2 is symmetrically provided with magnetic blocks 25. After the feeding tray 1 is sent to the guide roller frame 011, the feeding unit 05 clamps the second slots 23 to send each sealing ring frame 2 to one side of the sealing ring placement frame 8 to be clamped by the clamping mechanism 6.

[0030] The limiting mechanism 4 includes a slider 41 that slides on the slide bar frame 22. The two ends of the first spring 24 abut against the slider 41 and the slide bar frame 22 respectively.

[0031] During the process of the sealing ring frame 2 being clamped and sent to the detection unit 06 by the feeding unit 05, the side wall of the roller guide plate 71 set on the top of the roller limit frame 7 is used to squeeze the roller 45 to realize the displacement of the slider 41.

[0032] Furthermore, the adjustment mechanism 3 includes a guide rail 31 horizontally arranged on one side of the placement slot 12, a guide block 33 slidably fitted on the guide rail 31, and a plurality of push rods 35 for pushing the connecting push rod 42 evenly arranged along the longitudinal direction on the guide block 33.

The insert rod 36 is used to insert into the socket 32, thereby locking the position of the guide block 33, and the push rod 35 will not obstruct the removal of the sealing ring frame 2.

[0033] Meanwhile, the pallet transfer mechanism 5 includes a screw motor assembly 51 located in the middle of the workbench 01 and between the two guide roller frames 011. A slider seat 52 is slidably fitted on the screw motor assembly 51. A second double-headed cylinder 53 is provided on the top of the slider seat 52.

A first gripper 0541 for clamping the second slot 23 is provided at the bottom output end of the first double-headed cylinder 054.

[0034] Furthermore, the clamping mechanism 6 includes a fourth electric slide rail 61 horizontally arranged on one side of the sealing ring placement frame 8. A clamping assembly 62 is slidably fitted on the fourth electric slide rail 61. The clamping assembly 62 includes a slide rail seat 621 slidably fitted on the fourth electric slide rail 61. A second servo cylinder 622 is vertically arranged on the slide rail seat 621. The second servo cylinder 622 is equipped with a third servo cylinder 623 that can move vertically through a piston rod. The third servo cylinder 623 is arranged longitudinally. A rotary motor 624 that can move longitudinally is equipped on the piston rod of the third servo cylinder 623. A third double-headed cylinder 625 is rotatably arranged at the output end of the rotary motor 624. A third gripper 626 for clamping the sealing ring 07 is equipped at the output end of the third double-headed cylinder 625. The rotary motor 624 can realize the flipping of the sealing ring 07 and take pictures of both sides of the sealing ring 07.

[0035] Among them, the upper surface of the sealing ring placement rack 8 is provided with a sealing ring placement groove 81 for placing the sealing ring 07, and the sealing ring placement rack 8 is provided with an opening groove 82, which makes it easy to leave space for the third gripper 626.

[0036] In this embodiment, multiple feeding trays 1 are first placed on the tray support side plate 031 of the feeding rack 03, and the feeding trays 1 are fixed by the tray limiting block 033. The limiting grooves 14 on both sides of the feeding tray 1 cooperate with the limiting rod 022 to prevent displacement or shaking during the feeding process.

[0037] When feeding is required, the feeding rack 03 is moved to the corresponding height of the worktable 01 by the first electric slide rail 021, so that the target layer feeding tray 1 is aligned with the guide roller frame 011. Then, the slider seat 52 is moved by the screw motor group 51 in the tray transfer mechanism 5, and the second gripper 54 is driven by the second double-headed cylinder 53 to clamp the first slot 13 at the bottom of the feeding tray 1, thereby transferring the feeding tray 1 from the feeding rack 03 to the guide roller frame 011.

[0038] During the movement of the feeding pallet 1, a sealing ring frame 2 is installed in the placement groove 12 on the feeding pallet 1. The sealing ring frame 2 is magnetically attracted and fixed to the magnetic groove 121 by the bottom magnetic block 25, so that it remains stable during transportation. A placement rod 21 is installed on the front side of the sealing ring frame 2. Multiple sealing rings 07 are suspended on the placement rod 21 and are individually limited by the arc protrusion 211 to prevent the sealing rings 07 from tangling or overlapping.

[0039] Meanwhile, a limiting mechanism 4 is slidably installed on the slide bar frame 22 at the top of the sealing ring frame 2. The limiting mechanism 4 achieves elastic compression through the first spring 24, so that the limiting roller rod 43 always forms an upper limit on the sealing ring 07.

[0040] When the feeding pallet 1 reaches the guide roller frame 011, it is transferred to the second position by the feeding unit 05. The feeding unit 05 achieves three-dimensional positioning through the second electric slide rail 051, the third electric slide rail 052 and the first servo electric cylinder 053, and drives the first gripper 0541 to clamp the second slot 23 on the top of the sealing ring frame 2 through the first double-headed cylinder 054, so as to remove the sealing ring frame 2 from the feeding pallet 1 and transport it to the detection area.

[0041] Furthermore, during the process of the sealing ring frame 2 being sent to the clamping mechanism 6, the roller 45 will be squeezed by the roller guide plate 71, thereby causing the slider 41 to slide on the slide bar frame 22. The limiting roller rod 43 will no longer press against the sealing ring 07, and the sealing ring 07 can be freely removed. The roller limiting frame 7 is used to release the limiting state of the limiting mechanism 4.

[0042] When the sealing rings 07 are suspended in batches on the loading pallet 1, the operator does not need to remove the sealing ring holder 2. The guide block 33 is moved by the guide rail 31. The push rod 35 on the guide block 33 pushes the connecting push rod 42 in sequence, so that the slider 41 moves along the slide rod holder 22, thereby adjusting the pressing position of the limit mechanism 4 in batches. After the adjustment is completed, the insert rod 36 on the sliding frame 34 is inserted into the socket 32 ​​and locked by the action of the second spring 37, so that the limit mechanism 4 maintains a stable working state.

[0043] When the sealing ring holder 2 enters the inspection area, the clamping mechanism 6 starts to work. The clamping mechanism 6 drives the clamping assembly 62 to move to the target station through the fourth electric slide rail 61. Then, the second servo electric cylinder 622 and the third servo electric cylinder 623 cooperate to realize the vertical and longitudinal position adjustment. The rotary motor 624 drives the third double-headed cylinder 625 to rotate, thereby driving the third gripper 626 to clamp the sealing ring 07. At the same time, the sealing ring 07 can be flipped over by the rotary motor 624, so that both sides can be visually inspected.

[0044] During the inspection process, the visual inspection camera component 061 in the inspection unit 06 acquires images of the sealing ring 07 and transmits the images to the image display panel 062 for real-time display in order to make quality judgment. After the inspection is completed, qualified and unqualified sealing rings 07 are transferred to different areas on the worktable 01 by the clamping mechanism 6, and finally fall into the sealing ring collection box 08 whose position is defined by the collection box positioning block 012, so as to achieve classified collection.

[0045] Furthermore, the operator can remove the loading pallet 1 from the loading rack 03 using handle 11.

[0046] In this invention, through the coordinated design of the workbench 01, lifting platform 02, loading rack 03, and detection unit 06, a continuous and automated processing flow for the sealing ring 07 is achieved, from loading, transfer, limit adjustment, visual detection, to classification and collection. The lifting platform 02 works in conjunction with the multi-layer loading rack 03 to achieve layered storage and step-by-step feeding of the loading pallet 1, improving the continuity of feeding and reducing the frequency of manual replenishment. The loading pallet 1 works in conjunction with the magnetic sealing ring frame 2, and stable positioning is achieved through the magnetic groove 121 and the magnetic block 25, so that the sealing ring remains stable during handling and detection, improving transportation reliability.

[0047] The limiting mechanism 4 and the adjusting mechanism 3 work together to achieve batch adjustment and rapid adaptation of the upper limiting position of the sealing ring 07, ensuring a consistent positioning effect under different working conditions and improving changeover efficiency. The pallet transfer mechanism 5, the feeding unit 05 and the clamping mechanism 6 work together to achieve automatic transfer and precise gripping of the feeding pallet 1 and the sealing ring frame 2 between various workstations, reducing manual intervention and improving the consistency of the conveying cycle.
