Description

Technical Field

[0001] This utility model relates to the field of decelerator production equipment, specifically to an automatic O-ring feeding and assembly device for decelerators. Background Technology

[0002] In the manufacturing of decelerators, O-rings are critical sealing elements, and their assembly quality directly affects the performance and safety of the decelerator. Traditionally, the assembly of decelerator O-rings relies heavily on manual operation. Workers must manually remove each O-ring from the material pile and then place it onto the rotating shaft. This method is not only extremely inefficient, but the repetitive nature of the operation over a long period easily leads to worker fatigue, resulting in decreased operational precision. It becomes difficult to ensure that each O-ring is accurately placed in the designated position on the rotating shaft, and misalignment or displacement frequently occurs. This affects the sealing performance of the decelerator, potentially causing liquid or gas leakage at critical moments, thus reducing the reliability of the decelerator.

[0003] To overcome the drawbacks of traditional manual assembly, the industry has developed some automated O-ring assembly equipment, which has improved assembly efficiency and quality to some extent. However, due to the influence of various factors such as raw materials and production processes during the production of O-rings, their size and shape may deviate. These deviated O-rings are prone to defects such as twisting and folding during assembly. Existing O-ring assembly equipment does not have corresponding operating and handling mechanisms designed to address this issue, which may lead to poor sealing of the sluice gate due to O-ring twisting or folding defects, posing a potential risk to the quality of the sluice gate.

[0004] With the continuous expansion of the decelerator market and increasingly fierce competition, the industry's demand for efficient and precise O-ring assembly technology is becoming more and more urgent. Therefore, it is necessary to develop an automatic O-ring feeding and assembly device for decelerators to solve the problems existing in the current technology. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] This utility model provides an automatic O-ring feeding and assembly device for a decelerator. At least the technical problem it can solve is: how to improve the assembly efficiency and quality of the O-rings of the decelerator, and reduce the occurrence of poor sealing of the decelerator due to defects such as twisting and folding of the O-rings.

[0007] (II) Technical Solution

[0008] To solve the above-mentioned technical problems, this utility model provides the following technical solution: an automatic O-ring feeding and assembly device for a decelerator, comprising:

[0009] frame;

[0010] The feeding mechanism is mounted on the frame and includes a feeding channel for continuously conveying O-rings one by one;

[0011] Both the material distribution mechanism and the spreading mechanism are located on the frame. The material distribution mechanism is used to transfer the O-ring at the end of the feeding channel to the spreading mechanism, and the spreading mechanism is used to spread the O-ring.

[0012] An assembly mechanism, located on the frame, is used to transfer the O-rings on the spreading mechanism and fit them onto the rotating shaft in the rotating shaft fixture.

[0013] Furthermore, the aforementioned opening mechanism includes:

[0014] A push rod and a push rod drive, wherein the push rod includes a first guide portion in the shape of a frustum or a cone, and the push rod drive is mounted on a frame and is connected to the push rod drive.

[0015] Mounting block, fixed on push rod drive component or frame;

[0016] At least two support arms are slidably mounted on the mounting block. The at least two support arms are distributed in a ring-shaped interval along the outer periphery of the first guide portion and are combined to form a sleeve portion for O-ring fitting.

[0017] The number of elastic elements is the same as that of the support arms and they are set one to one. One end of the elastic element is connected to the mounting block and the other end is connected to the corresponding support arm. The elastic element has a spring force that drives the support arm to slide toward the push rod so that the support arm abuts against the first guide part.

[0018] The push rod drive is used to drive the push rod to move up and down, thereby causing at least two support arms to overcome the elastic force of the elastic element and move away from each other, so as to open the O-ring fitted on the sleeve part.

[0019] Further configuration: the aforementioned support arm has at least three parts, the outer side of the support arm is arc-shaped, and the at least three support arms are combined to form a cylindrical sleeve.

[0020] In a further configuration, the aforementioned material distribution mechanism includes a sleeve rod and a sleeve rod drive assembly. The bottom of the sleeve rod is provided with a second guide portion in the shape of an inverted cone or an inverted frustum. The sleeve rod drive assembly is mounted on the frame and is connected to the sleeve rod in a transmission manner. The sleeve rod drive assembly is used to drive the sleeve rod to reciprocate between the feeding channel and the spreading mechanism, so as to transfer the O-ring at the very end of the feeding channel to the spreading mechanism.

[0021] Further, the aforementioned sleeve rod is composed of at least two annularly spaced sleeve claws. The discharge end of the feeding channel is provided with a receiving groove for accommodating a single O-ring. The bottom of the receiving groove is provided with a clearance hole for the sleeve claw to pass through. There is a support arm gap between adjacent support arms. The number of clearance holes, support arm gaps and sleeve claws are all the same and are set in a one-to-one correspondence.

[0022] When the sleeve rod drive assembly drives the sleeve rod to move to the receiving groove, the sleeve claws and the clearance holes are inserted one by one to fit the O-ring at the end of the feeding channel onto the sleeve rod; when the sleeve rod drive assembly drives the sleeve rod to move to the sleeve joint, the sleeve claws and the support arm gaps are inserted one by one to fit the O-ring coaxially on the outside of the sleeve joint.

[0023] Furthermore, the aforementioned automatic O-ring feeding and assembly device for the decelerator also includes a vision inspection mechanism. The vision inspection mechanism is located on the frame and above the receiving slot. The vision inspection mechanism is used to detect whether there are O-rings in the receiving slot.

[0024] Furthermore, the aforementioned feeding mechanism is provided in at least two parts, and the number of the material distribution mechanism, the spreading mechanism and the feeding mechanism are all the same, and they are set up one-to-one.

[0025] Further configuration: The aforementioned assembly mechanism includes gripping fingers, a robotic arm, a push plate, and a push plate drive. The number of gripping fingers is the same as the number of feeding channels and they are arranged in a one-to-one correspondence. The robotic arm is mounted on the frame. The push plate drive and several gripping fingers are mounted on the output end of the robotic arm. The output end of the push plate drive is connected to the push plate. The push plate has a through hole for the output end of the gripping fingers to pass through.

[0026] Among them, the grasping fingers are used to grasp or release the O-ring, the robot arm is used to drive several grasping fingers to reciprocate between the spreading mechanism and the rotating fixture, and the push plate drive is used to drive the push plate to move along the output end of the grasping fingers so as to push the O-ring out of the output end of the grasping fingers.

[0027] (III) Beneficial Effects

[0028] Compared with the prior art, the automatic O-ring feeding and assembly device for a decelerator provided by this utility model has the following advantages:

[0029] 1. When using the automatic O-ring feeding and assembly device for the decelerator provided by this utility model, firstly, the feeding mechanism continuously conveys O-rings one by one through the feeding channel, while the distributing mechanism moves the O-ring at the end of the feeding channel to the spreading mechanism; then, the spreading mechanism spreads the O-ring to a specific size and shape; finally, the assembly mechanism transfers the O-ring on the spreading mechanism to the top of the rotating shaft of the rotating shaft fixture, and precisely fits the O-ring onto the rotating shaft, completing the O-ring assembly. It can be seen that this utility model, through the coordinated operation of various mechanisms, achieves automated feeding and assembly of the decelerator's O-rings. The entire feeding and assembly process requires no manual intervention, significantly improving the assembly efficiency and quality of the O-rings.

[0030] 2. This utility model first uses a spreading mechanism to spread the O-ring to a specific size and shape, and then uses an assembly mechanism to assemble the O-ring. This not only makes it easier and more accurate for the O-ring to be placed on the designated position of the rotating shaft during the assembly process, but also effectively avoids possible offset or misalignment of the O-ring during assembly, thereby ensuring the positional accuracy of the O-ring assembly and further improving the assembly quality of the O-ring. It also greatly reduces the occurrence of poor sealing of the depressor due to defects such as twisting or folding of the O-ring, thereby ensuring the sealing effect of the depressor.

[0043] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0044] This utility model provides an automatic O-ring feeding and assembly device for a decelerator, which is used to solve the problem of how to improve the assembly efficiency and quality of the O-ring 6 of the decelerator, and reduce the problem of poor sealing of the decelerator caused by defects such as twisting and folding of the O-ring 6.

[0045] See Figure 1 As shown, Figure 1 The figure shows a perspective view of the automatic O-ring feeding and assembly device for the decelerator in the embodiment. The automatic O-ring feeding and assembly device for the decelerator includes a frame 1, a feeding mechanism 2, a distributing mechanism 3, a spreading mechanism 4, and an assembly mechanism 5.

[0046] The feeding mechanism 2 is mounted on the frame 1 and includes a feeding channel 21 for continuously feeding O-rings 6 one by one.

[0047] Both the material distribution mechanism 3 and the spreading mechanism 4 are mounted on the frame 1. The material distribution mechanism 3 is used to transfer the O-ring 6 at the very end of the feeding channel 21 to the spreading mechanism 4. The spreading mechanism 4 is used to spread the O-ring 6.

[0048] Assembly mechanism 5 is mounted on frame 1 and is used to transfer O-ring 6 on spreading mechanism 4 and fit it onto the rotating shaft in rotating shaft fixture 7.

[0049] When using the automatic O-ring feeding and assembly device for the decelerator described above, the feeding mechanism 2 first continuously feeds O-rings 6 one by one through the feeding channel 21, while the distributing mechanism 3 moves the O-ring 6 at the end of the feeding channel 21 to the spreading mechanism 4. Then, the spreading mechanism 4 spreads the O-ring 6 to a specific size and shape. Finally, the assembly mechanism 5 transfers the O-ring 6 from the spreading mechanism 4 to the top of the rotating shaft of the rotating shaft fixture 7, and precisely fits the O-ring 6 onto the rotating shaft, completing the assembly of the O-ring 6. It can be seen that this utility model, through the coordinated cooperation of various mechanisms, realizes the automated feeding and assembly of the decelerator O-ring 6. The entire feeding and assembly process requires no manual intervention, significantly improving the assembly efficiency and quality of the O-ring 6.

[0050] Furthermore, this invention first uses the spreading mechanism 4 to spread the O-ring 6 to a specific size and shape, and then uses the assembly mechanism 5 to assemble the O-ring 6. This not only makes it easier and more accurate for the O-ring 6 to be fitted onto the designated position on the rotating shaft during the assembly process, effectively avoiding possible offset or misalignment of the O-ring 6 during assembly, thus ensuring the positional accuracy of the O-ring 6 assembly and further improving the assembly quality of the O-ring 6, but also greatly reduces the occurrence of poor sealing of the depressor due to defects such as twisting or folding of the O-ring 6, thereby ensuring the sealing effect of the depressor.

[0051] The aforementioned feeding mechanism 2 can use an existing combination of mechanical vibratory feeder 22 and linear vibrator 23 for feeding.

[0052] See Figure 3 and Figure 4 As shown, Figure 3 This is a partial structural diagram of the frame, feeding mechanism, distributing mechanism, and spreading mechanism in the embodiment. Figure 4The diagram shows a cross-sectional view of the spreading mechanism in one embodiment. The spreading mechanism 4 includes a push rod 41, a push rod drive member 42, a mounting block 43, elastic members 44, and at least two support arms 45. The push rod 41 includes a frustum-shaped or conical first guide portion 411. The push rod drive member 42 is mounted on the frame 1 by screwing or welding and is drively connected to the push rod 41. The mounting block 43 is fixed to the push rod drive member 42 or the frame 1 by screwing or welding. The support arms 45 are slidably connected to the mounting block 43. At least two support arms 45 are distributed annularly at intervals along the outer periphery of the first guide portion 411 and combine to form a fitting portion 46 for fitting O-rings 6. The number of elastic members 44 is the same as the number of support arms 45, and they are arranged in a one-to-one correspondence. One end of the elastic member 44 is connected to the mounting block 43, and the other end is connected to the corresponding support arm 45. The elastic member 44 has a spring force that drives the support arm 45 to slide toward the push rod 41 so that the support arm 45 abuts against the first guide portion 411. The push rod drive member 42 is used to drive the push rod 41 to move up and down, thereby causing at least two support arms 45 to overcome the spring force of the elastic member 44 and move away from each other, so as to open the O-ring 6 fitted on the sleeve portion 46. Thus, when the spreading mechanism 4 is in use, firstly, the material distribution mechanism 3 transfers the O-ring 6 at the end of the feeding channel 21 and fits it onto the fitting part 46. Then, the push rod drive member 42 drives the push rod 41 to rise, and through the first guide part 411, it drives at least two support arms 45 to simultaneously overcome the elastic force of the elastic member 44 and move away from each other, so as to spread the O-ring 6 fitted onto the fitting part 46. Next, the material distribution mechanism 3 leaves the spreading mechanism 4 and moves to the feeding mechanism 2 to grab the next O-ring 6 from the feeding channel 21. At the same time, the assembly mechanism 5 grabs the O-ring 6 and leaves the fitting part 46. Finally, the push rod drive member 42 drives the push rod 41 to fall, and at least two support arms 45 move closer to each other under the elastic force of the corresponding elastic member 44 so that the next O-ring 6 can be smoothly fitted onto the fitting part 46. It can be seen that the opening mechanism 4 uses the lifting and lowering motion of the push rod 41 and the elastic force of the elastic element 44 to drive at least two support arms 45 to move away from or towards each other synchronously, thereby achieving stable opening of the O-ring 6, ensuring that the O-ring 6 is of uniform size after opening, which is convenient for subsequent accurate fitting onto the rotating shaft and improving the assembly quality.

[0053] The aforementioned push rod drive component 42 can use existing linear drive mechanisms such as telescopic cylinders or telescopic poles, and its output end is connected to the push rod 41 by means of integral connection or welding. The aforementioned elastic component 44 can use existing compression springs or tension springs.

[0054] See Figure 3 and Figure 4As shown, in one embodiment of the support arm 45, there are at least three support arms 45. The outer surface of the support arm 45 is arc-shaped, and at least three support arms 45 are combined to form a cylindrical sleeve portion 46. In this way, the cylindrical sleeve portion 46 can make the O-ring 6 more evenly stressed during the opening process, avoiding problems such as damage or breakage of the O-ring 6 due to excessive local stress, ensuring the stability of its shape and size, thereby further improving the opening quality and stability of the O-ring 6.

[0055] See Figure 3 and Figure 5 As shown, Figure 5 This is a perspective view of the material distribution mechanism in one embodiment. The material distribution mechanism 3 includes a sleeve rod 31 and a sleeve rod drive assembly 32. The bottom of the sleeve rod 31 has a second guide portion 311 in the shape of an inverted cone or frustum. The drive component of the sleeve rod 31 is mounted on the frame 1 by screwing or welding and is connected to the sleeve rod 31 in a transmission manner. The sleeve rod drive assembly 32 drives the sleeve rod 31 to reciprocate between the feeding channel 21 and the spreading mechanism 4, transferring the O-ring 6 at the very end of the feeding channel 21 to the spreading mechanism 4. Thus, driven by the sleeve rod drive assembly 32, the sleeve rod 31 can accurately transfer the O-ring 6 at the very end of the feeding channel 21 to the spreading mechanism 4, realizing the material distribution function of the O-ring 6, ensuring that one O-ring 6 is transferred each time, and improving the accuracy and efficiency of material distribution. The second guide portion 311 guides the O-ring 6 to smoothly be put on or removed from the sleeve rod 31.

[0056] See Figure 3 and Figure 5 As shown, in one embodiment of the sleeve drive assembly 32, the sleeve drive assembly 32 includes a translation drive member 321 and a lifting drive member 322 connected to each other. One of the translation drive member 321 and the lifting drive member 322 is mounted on the frame 1 by means of screwing or welding, and the output end of the other is connected to the sleeve 31 by means of screwing or welding. The translation drive member 321 is used to drive the sleeve 31 to move between the feeding channel 21 and the spreading mechanism 4, so that the sleeve 31 is positioned opposite the feeding channel 21 or the spreading mechanism 4. The lifting drive member 322 is used to drive the sleeve 31 to move up and down towards the feeding channel 21 or the spreading mechanism 4. In this way, the translation drive member 321 and the lifting drive member 322 combined drive the sleeve 31, which can realize the transfer of the O-ring 6 at the end of the feeding channel 21 to the spreading mechanism 4.

[0057] Both the translation drive 321 and the lifting drive 322 mentioned above can use existing linear drive mechanisms such as telescopic cylinders and telescopic poles.

[0058] See Figure 3 , Figure 4 and Figure 5As shown, in one embodiment of the sleeve 31, the sleeve 31 consists of at least two annularly spaced claws 312. The discharge end of the feeding channel 21 has a receiving groove 24 for accommodating a single O-ring 6. The bottom of the receiving groove 24 has a clearance hole 25 for the claws 312 to pass through. There is a support arm gap 47 between adjacent support arms 45. The number of clearance holes 25, support arm gaps 47, and claws 312 are all the same, and they are arranged in a one-to-one correspondence. When the sleeve rod drive assembly 32 drives the sleeve rod 31 to move to the receiving groove 24, the sleeve claw 312 and the clearance hole 25 are inserted one by one to fit the O-ring 6 at the end of the feeding channel 21 onto the sleeve rod 31. When the sleeve rod drive assembly 32 drives the sleeve rod 31 to move to the sleeve part 46, the sleeve claw 312 and the support arm gap 47 are inserted one by one to fit the O-ring 6 coaxially on the outside of the sleeve part 46. At this time, the outer diameter of the sleeve part 46 is increased so that the outer diameter of the sleeve part 46 is greater than the outer diameter of the sleeve rod 31. At the same time, the sleeve rod drive assembly 32 drives the sleeve rod 31 to rise and pull away from the sleeve part 46, so that the O-ring 6 can be fitted onto the sleeve part 46. Thus, the material distribution mechanism 3, through the corresponding insertion design of the sleeve claw 312 with the clearance hole 25 and the support arm 45, can realize the accurate transfer of the O-ring 6 between the feeding channel 21, the sleeve rod 31 and the spreading mechanism 4, ensuring that the O-ring 6 is accurately positioned during the transfer process and is not easy to fall off or deform, thereby improving the reliability and stability of the entire device.

[0059] See Figure 1 As shown, based on the above embodiment, the automatic O-ring feeding and assembly device for the decelerator also includes a vision inspection mechanism 8. The vision inspection mechanism 8 is mounted on the frame 1 by screwing or welding and is located above the receiving groove 24. The vision inspection mechanism 8 is used to detect whether there are O-rings 6 in the receiving groove 24. Thus, the vision inspection mechanism 8 can detect the presence of O-rings 6 in the receiving groove 24 in real time, ensuring that the O-rings 6 are supplied in place before proceeding with subsequent material distribution operations. This effectively avoids material leakage during subsequent assembly and can also promptly detect whether the feeding mechanism 2 is short of material, allowing for timely replenishment of O-rings 6 and preventing production interruptions due to material shortages. This effectively improves the continuity and automation of production.

[0060] The aforementioned visual inspection mechanism 8 can use an existing CCD camera, which can not only quickly detect whether there is an O-ring 6 in the receiving slot 24, but also detect whether the quality of the O-ring 6 meets the requirements, thereby ensuring the assembly quality of the O-ring 6.

[0061] See Figure 1As shown, based on any of the above embodiments, the number of feeding mechanisms 2 is at least two. The number of distributing mechanisms 3, spreading mechanisms 4, and feeding mechanisms 2 are all the same, and they are arranged in a one-to-one correspondence. Thus, this utility model provides multiple feeding mechanisms 2 and corresponding distributing mechanisms 3 and spreading mechanisms 4. Each feeding mechanism 2 can be used to supply O-rings 6 of the same specification. In this way, the automatic O-ring feeding and assembly device can feed multiple O-rings 6 simultaneously, greatly improving production efficiency and meeting the needs of large-scale production. Each feeding mechanism 2 can also be used to supply O-rings 6 of different specifications. In this way, when the automatic O-ring feeding and assembly device changes the specification of the O-rings 6 to be assembled, it is only necessary to switch the corresponding feeding mechanism 2, distributing mechanism 3, and spreading mechanism 4 to feed the O-rings. There is no need to make complex adjustments and modifications to the equipment, which effectively improves the flexibility and efficiency of production and meets diverse production needs.

[0062] See Figure 1 and Figure 2 As shown, Figure 2 for Figure 1 The enlarged schematic diagram at point A shows that, in one embodiment of the assembly mechanism 5, the assembly mechanism 5 includes gripping fingers 51, a robotic arm 52, a push plate 53, and a push plate drive 54. The number of gripping fingers 51 is the same as the number of feeding channels 21, and they are arranged in a one-to-one correspondence. The robotic arm 52 is mounted on the frame 1 by screwing or welding. The push plate drive 54 and several gripping fingers 51 are all mounted on the output end of the robotic arm 52 by screwing or welding. The output end of the push plate drive 54 is connected to the push plate 53 by screwing or welding. The push plate 53 has through holes 531 for the output ends of the gripping fingers 51 to pass through. The gripping fingers 51 are used to grip or release O-rings 6. The push plate drive 54 drives the push plate 53 to move along the output ends of the gripping fingers 51 to push the O-rings 6 out of the output ends of the gripping fingers 51. The robotic arm 52 drives several gripping fingers 51 to reciprocate between the spreading mechanism 4 and the rotating fixture 7. Thus, in use, the O-ring 6 is fitted onto the output end of the gripping finger 51. The gripping finger 51 grips and releases the O-ring 6 by expanding and contracting its output end. The robotic arm 52 and several gripping fingers 51 work together to simultaneously and accurately transfer several O-rings 6 onto the corresponding rotating shaft. When the gripping finger 51 releases the O-ring 6, the push plate drive 54 drives the push plate 53 to move outward along the output end of the gripping finger 51, simultaneously pushing several O-rings 6 off the output end of the corresponding gripping finger 51. This effectively prevents the O-ring 6 from remaining fitted onto the output end of the gripping finger 51 when it contracts and releases. In summary, the gripping finger 51, the robotic arm 52, and the push plate drive 54 work together to ensure that the O-ring 6 is accurately and stably fitted onto the rotating shaft, thereby improving assembly efficiency and quality.

[0063] The aforementioned finger gripper 51 can use an existing O-ring finger gripper cylinder, the robotic arm 52 can use an existing robotic arm, and the push plate drive 54 can use an existing telescopic cylinder, telescopic pole, or other linear drive mechanism.
