Technical Field

[0001] The present invention belongs to the field of seal processing, and particularly relates to an intelligent feeding and processing device for rubber seals. Background Art

[0002] The rubber industry is one of the important basic industries. It not only provides daily-use and medical light industrial rubber products indispensable for people's daily life, but also provides various rubber production equipment or rubber components for heavy industries and emerging industries such as mining, transportation, construction, machinery, and electronics. Sealing rings are one of them, and among the sealing rings, O-ring seals are the most commonly used. O-ring seals are the most widely used rubber seals in various mechanical equipment. Its cross-sectional structure is extremely simple and has a self-sealing function. The sealing performance is reliable, and it is mainly used for static sealing and reciprocating motion sealing;

[0003] During the production process of O-ring seals, basic processes such as plasticating, mixing, calendering, forming, vulcanizing, and trimming are required. Each process has different requirements for the products. After the O-ring seals are vulcanized and processed, the plastic semi-finished products will be made into high-elastic final products and trimmed. However, in the prior art, when trimming the vulcanized O-ring seals, usually the processing personnel manually pick up the O-ring seals, which not only has a low degree of automation, but also requires picking and sorting the randomly stacked sealing rings, reducing the efficiency;

[0004] Therefore, this application proposes an intelligent feeding and processing device for rubber seals to improve the above-mentioned defects. Summary of the Invention

[0036] Example 1: Please refer to Figures 1 - 6 , the specific embodiments of the present invention are as follows:

[0037] An intelligent feeding and processing device for rubber seals, whose structure includes a first machine base 1, a second machine base 2, a manipulator 3 and a feeding device 4. A second machine base 2 is provided on one side of the first machine base 1. Feeding devices 4 are installed on the tops of both the first machine base 1 and the second machine base 2, and the feeding device 4 can be driven to rotate by the controller in the machine base. A manipulator 3 is installed between the first machine base 1 and the second machine base 2. The manipulator 3 can rotate to alternately load O-ring seals from both sides for the two groups of feeding devices 4.

[0038] Please refer to Figure 1 , the first machine base 1 and the second machine base 2 can form a two-station processing. After the first machine base 1 completes the feeding of the O-ring seal, it can supply materials for the next process, and the manipulator 3 can rotate to load materials for the second machine base 2, thus forming an alternating cycle to improve the efficiency of processing and feeding.

[0039] Please refer to Figure 2 , the feeding device 4 includes a feeding tray 41, placing grooves 42, a support frame member 43, an ejection mechanism 44 and a dust cover 45. A number of placing grooves 42 are annularly arranged on the feeding tray 41. The number of placing grooves 42 can form multi-station feeding, and support frame members 43 capable of stacking and feeding O-ring seals are installed on all of them. An ejection mechanism 44 capable of jacking up and discharging the O-ring seals on the support frame member 43 is installed inside the turntable 41. A dust cover 45 is movably clamped on the feeding tray 41, and the dust cover 45 can block the ejection mechanism 44 to prevent dust from falling in.

[0040] Please refer to Figures 3 - 4 , the support frame member 43 includes a main frame 221, a positive and negative driving member 222, a connecting frame 223, a turntable 224, a support plate 225 and a limiting plate 226. A positive and negative driving member 222 is installed at the center of the main frame 221. Connecting frames 223 are connected to both the upper and lower ends of the positive and negative driving member 222. The outer sides of the two connecting frames 223 are respectively connected to the turntable 224. The two turntables 224 are respectively located at the upper and lower ends of the main frame 221, and are respectively connected to a support plate 225 and a limiting plate 226. A number of support plates 225 and limiting plates 226 are annularly arranged around the turntable 224.

[0041] Please refer to Figure 4, the turntable 224 includes a fixed rod 31, a chute 32, a sliding column 33, a connecting rod 34, and a positioning column 35. A number of fixed rods 31 are arrayed on the turntable 224, and two sets of chutes 32 are provided on each of the number of fixed rods 31. A sliding column 33 is slidably engaged with each chute 32. The height of the sliding column 33 is greater than the thickness of the fixed rod 31, so that the sliding column 33 will not disengage from the chute 32 during sliding. The bottom of the sliding column 33 is connected to the connecting rod 34, and the other end of the connecting rod 34 is rotatably engaged with the positioning column 35. The positioning column 35 is fixed on the main frame 221.

[0042] Please refer to Figure 4 , the positive and negative driving member 222 drives the turntables 224 at the upper and lower ends to rotate. By means of the rotation of the turntable 224, the sliding column 33 will be driven to move in the chute 32, thereby driving the connecting rod 34 connected to the sliding column 33 to move together. As the connecting rod 34 moves, the supporting plate 225 connected thereto will be driven to expand outwards. With the aid of the supporting plate 225, O-ring seals with different diameters can be supported.

[0043] Please refer to Figures 3 - 5 , a limiting groove 227 is provided on the outer side of each of the number of supporting plates 225.

[0044] Please refer to Figures 3 - 5 , a number of limiting plates 226 and a number of supporting plates 225 are arranged alternately. When the limiting plate 226 expands outwards driven by the lower turntable 224, it will fit with the supporting plate 225, playing a limiting role on the number of supporting plates 225, so that the supporting plate 225 can only expand in a specific direction, increasing the stability of the supporting plate 225.

[0045] Please refer to Figure 6 , the positive and negative driving member 222 includes a lower driving wheel 51, an upper driving wheel 52, a linkage wheel 53 and a main shaft 54.

The two sets of linkage wheels 53 are in gear engagement with the upper driving wheel 52 and the lower driving wheel 51. The centers of the two sets of linkage wheels 53 are rotatably engaged through the main shaft 54. By the clockwise rotation of the lower driving wheel 51, the two sets of linkage wheels 53 engaged therewith will be driven to rotate synchronously. By means of the rotation of the two sets of linkage wheels 53, the upper driving wheel 52 at the top will be driven to rotate counterclockwise synchronously, so as to achieve the effect of positive and negative rotation, and drive the two turntables 224 at the upper and lower ends to rotate in the positive and negative directions together, driving the number of supporting plates 225 and limiting plates 226 thereon to expand outwards to support the O-ring seal.

[0046] Embodiment 2: Please refer to Figures 7 - 9 , the specific embodiments of the present invention are as follows:

[0047] Please refer to Figure 7 , the ejection mechanism 44 includes a cylinder 11, a hexagonal pyramid 12, a ejector pin 13, a sliding ring 14 and a clamping block 15. A cylinder 11 is provided at the bottom of the feeding tray 41. The piston rod of the cylinder 11 is on the same center line as the feeding tray 41 and is located inside the machine base. A hexagonal pyramid 12 is installed on the piston rod of the cylinder 11 and drives the hexagonal pyramid 12 to move up and down. A number of ejector pins 13 are slidably fitted on the six contact surfaces of the hexagonal pyramid 12. A number of ejector pins 13 are located inside the feeding tray 41 and are slidably fitted with the feeding tray 41. The other ends of a number of ejector pins 13 are installed with a sliding ring 14. A number of clamping blocks 15 are fixed on the inner wall of the sliding ring 14. The clamping blocks 15 are slidably fitted with the limiting grooves 227, which can limit the sliding of the sliding ring 14 on the support plate 225 and increase the stability, so that the sliding ring 14 can only slide up and down on the support plate 225 under the action of the ejector pins 13.

[0048] Please refer to Figure 7 , the sliding ring 14 is on the same center line as the support framework 43 and is located outside a number of support plates 225 and is slidably fitted with a number of support plates 225, which can support the bottom of the O-ring placed on the support plate 225, so that the O-rings will be stacked on the sliding ring 14, facilitating the discharging of the O-rings when the sliding ring 14 moves upward later. The sliding ring 14 is made of a telescopic rubber material, and the contact surface with the support plate 225 is a smooth surface, so that the sliding ring 14 can be adjusted by expanding together with the expansion of the support framework 43, and is applicable to O-rings of different diameters.

[0049] Please refer to Figure 8 , the ejector pin 13 includes a top ball 131, a push rod 132 and a spring 133. The top ball 131 is in contact with the hexagonal pyramid 12. A push rod 132 is fixed at the end of the top ball 131 away from the hexagonal pyramid 12. The push rod 132 is a bendable rubber rod. A spring 133 is installed on the push rod 132. The spring 133 can reset the top ball 131 by the extrusion when the top ball 131 moves.

[0050] Please refer to Figures 8 - 9 , the feeding tray 41 includes a through groove 411, a fixing plate 412 and a guiding tube 413. A number of through grooves 411 are annularly arranged inside the feeding tray 41. A number of through grooves 411 correspond to the positions of a number of groups of support frameworks 43 one by one. A fixing plate 412 is fixedly installed inside a number of through grooves 411. One side of the fixing plate 412 is connected to the other end of the spring 133, which can enable the spring 133 to be squeezed by force. The other side of the fixing plate 412 is fixed with a guiding tube 413. The end of the guiding tube 413 close to the sliding ring 14 is a curved conduit inclined upward, which can enable the ejector pin 13 to eject upward when moving outward, thereby driving the sliding ring 14 to move upward. The ejector pin 13 is located inside the guiding tube 413 and is slidably fitted with the guiding tube 413.

[0051] Please refer to Figures 7 - 9 Figures 7 - 9 , the hexagonal pyramid 12 is driven up and down by the air cylinder 11, which can drive a number of ejector pins 13 in contact with the hexagonal pyramid 12 to move in the through groove 411 of the feeding tray 41, and under the guiding action of the guiding tube 413, move upward and eject, driving the sliding ring 14 connected to the other end of the ejector pin 13 to slide on the support plate 225. With the upward movement of the sliding ring 14, the O-ring located on the support plate 225 can be pushed upward and discharged.

[0052] Based on the above embodiments, the specific working principle is as follows:

[0053] When the O-ring is vulcanized and processed during production, the gripper of the manipulator 3 sequentially places the vulcanized O-rings on several groups of support skeleton members 43 of the feeding tray 41. Driven by the drive motor in the main frame 221, the drive wheel 51 rotates clockwise, which will drive two sets of linkage wheels 53 engaged with it to rotate synchronously. With the help of the two sets of linkage wheels 53, the upper drive wheel 52 at the top can be driven to rotate counterclockwise synchronously, so as to achieve the effect of rotating in both forward and reverse directions, and drive the two turntables 224 at the upper and lower ends connected to it to rotate in both forward and reverse directions respectively;

[0054] As the two turntables 224 rotate, a number of sliding columns 33 arranged in an array will move in the sliding grooves 32, thereby driving the connecting rod 34 connected to the bottom of the sliding column 33 to move. As the connecting rod 34 moves, the support plate 225 and the limit plate 226 connected to it will expand outward. The limit plate 226 can guide and limit the support plate 225. With the help of the support plate 225, the O-rings grasped by the manipulator 3 can be supported and placed, so that the O-rings can be stacked on the support skeleton members 43;

[0055] When the support skeleton members 43 on the first base 1 are all loaded with O-rings, the manipulator 3 will rotate to the second base 2 and repeat the above steps to complete the loading of the O-rings on the second base 2. At the same time, the air cylinder 11 drives the hexagonal pyramid 12 to rise, which can drive a number of ejector pins 13 in contact with the hexagonal pyramid 12 to move in the through groove 411 of the feeding tray 41, and under the guiding action of the guiding tube 413, move upward and eject, driving the sliding ring 14 connected to the other end of the ejector pin 13 to slide on the support plate 225. With the upward movement of the sliding ring 14, the stacked O-rings on the support plate 225 can be pushed upward and fed as needed, which is convenient for the processing personnel to take and perform subsequent trimming processing on the O-rings, thus forming a reciprocating cycle.

[0056] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common general knowledge in the art. And the present invention is mainly used to protect mechanical devices. Therefore, the control method and circuit connection of the present invention will not be explained in detail.

[0058] The above is only the specific implementation manner of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present application can easily think of changes or substitutions, and all should be covered within the protection scope of the present application.
