Description

Technical Field

[0001] The utility model relates to the technical field of glue application, in particular to a glue application structure for the outer wall of a bearing. Background Art

[0002] In modern industrial production, bearings, as key components, are widely used in various mechanical devices. To ensure the performance and service life of bearings, it is usually necessary to apply special glue to the outer ring of the bearings to achieve purposes such as rust prevention, enhanced sealing performance, or improved running smoothness.

[0003] However, the existing double-station automatic equipment still has some significant defects:

[0004] The glue application efficiency is low. Usually, the structures for loading, glue application, and unloading are respectively set at each station, and the glue application process is relatively long, resulting in the idling of the loading and unloading mechanisms and affecting the glue application efficiency. If multiple stations are used to improve the glue application efficiency, problems such as increased costs and large floor areas will also occur.

[0005] Currently, many devices have insufficient accuracy in bearing glue application. If the bearing is not fixed firmly during glue application, vibration will occur, resulting in a large deviation in the coating position. This method is not only inefficient but also has an uncontrollable accuracy rate.

[0006] The glue application uniformity is poor. On the premise of the above-mentioned insufficient accuracy, due to the product not being fixed properly, the situation of uneven glue application will also occur. The uneven glue application layer may affect the performance and life of the bearing.

[0007] In summary, although the existing automatic glue application structure has improved the production efficiency of bearing glue application to a certain extent, there are still obvious deficiencies in terms of detection efficiency and accuracy, glue application uniformity, and material loss rate, etc., and further technological innovation and optimization are urgently needed.

The following embodiments are only used to illustrate the technical solution of the present application more clearly, so they are only examples and cannot be used to limit the protection scope of the present application.

[0070] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs; the terms used herein are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion.

[0071] In the description of the embodiments of this application, technical terms such as "first" and "second" are only used to distinguish different objects and cannot be understood as indicating or implying relative importance or implicitly indicating the quantity, specific order or primary-secondary relationship of the indicated technical features. In the description of the embodiments of this application, the meaning of "a plurality" is more than two, unless otherwise specifically defined.

[0072] Referring to "embodiment" herein means that a specific feature, structure or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

Similarly, "a plurality of groups" refers to more than two groups (including two groups), and "a plurality of pieces" refers to more than two pieces (including two pieces).

[0076] As described in the background art, usually, the structures for loading, gluing, and unloading are respectively set at each station. However, the gluing process is relatively long, resulting in the idling of the loading and unloading mechanisms, which affects the gluing efficiency. If multiple stations are used to improve the gluing efficiency, it will also cause problems such as increased costs and a large floor area. At the same time, when gluing, the bearing is often clamped and rotated by only one jaw. During rotation, the bearing will shake due to rotation, thus affecting the gluing accuracy and uniformity.

[0077] Based on the above considerations, in order to solve the problems of poor working efficiency, poor gluing accuracy, and poor gluing uniformity of the traditional gluing structure for the outer wall of the bearing.

[0078] Embodiment 1

[0079] As Figures 1 to 6 shown, this embodiment provides a gluing structure for the outer wall of a bearing, which mainly includes a loading mechanism 100 and a gluing station.

[0080] First of all, the loading mechanism 100 is designed to carry the material, that is, the bearing, and drive the material to move horizontally. Specifically, the loading mechanism 100 includes a first-level platform 102, which is slidably connected to the first slide rail 1021 and is driven by a first cylinder 101. Such a design enables the first-level platform 102 to move smoothly and precisely on the first slide rail 1021.

[0081] Furthermore, a secondary platform 1022 is provided on the primary platform 102, and the secondary platform 1022 can move in a horizontal direction perpendicular to the moving direction of the primary platform 102. This vertically intersecting movement mode provides greater flexibility and accuracy for the precise transplanting of materials.

[0082] To carry the materials, a rack 103 is connected to the secondary platform 1022. The rack 103 is designed in a U-shaped structure, and a feeding port 1032 is provided at its upper end for convenient placement of the materials. Below the feeding port 1032, a clamping port 1033 for a three-jaw cylinder to clamp is provided. In this embodiment, a packaging plate is connected to the upper end of the side wall of the rack 103, and the hollow part between the packaging plate and the U-shaped inner cavity is the clamping port 1033. Such a design enables the materials to be stably and accurately clamped on the rack 103. In another embodiment, the rack 103 is designed in a V-shaped structure, specifically V-shaped at the lower end of the clamping port 1033, which can better position the materials and facilitate the three-jaw cylinder to clamp and load the materials.

[0083] To detect the position of the materials, a first photoelectric sensor 1031 is also provided on the side wall of the rack 103. This sensor can irradiate into the clamping port 1033 to accurately sense the presence and position of the materials, further improving the accuracy.

[0084] As Figure 3 shown, to further improve the transplanting accuracy and stability of the materials, the width of the rack 103 is designed to be the same as the width of the materials. Such a design enables the materials to be placed more stably on the rack 103, reducing the possible shaking and offset during the transplanting process.

[0085] At the same time, vertical lifting limit blocks 105 are respectively provided on both sides of the rack 103. These limit blocks 105 are connected to the drive shaft of the second cylinder 104 and can lift along the side wall of the rack 103. When the three-jaw cylinder clamps the materials from the left side of the rack 103, the limit block 105 on the right side of the rack 103 is lifted to block the right side of the materials, so that the materials will not shift when being clamped. Such a design further limits the moving range of the materials on the rack 103 and improves the transplanting accuracy and stability.

[0086] As Figure 3 shown, a feeding vibrating disk 106 is also provided on the moving path of the feeding mechanism 100. The output end of the feeding vibrating disk 106 is docked with the feeding port 1032, and an arc-shaped baffle 1034 for buffering and limiting the materials is connected to the feeding port 1032, which can ensure the feeding quantity of the materials and buffer and limit the materials.

[0087] Meanwhile, in this embodiment, the output end of the feeding vibrating disk 106 is located at both ends of the moving path of the feeding mechanism 100, and the rack 103 can carry two materials each time. Therefore, it just returns to the original position after one cycle, improving work efficiency. Meanwhile, in another embodiment, the output end of the feeding vibrating disk 106 can be located at any position of the moving path of the feeding mechanism 100, such as the middle of the moving path. The feeding mechanism 100 takes materials from the middle and feeds them to both ends respectively.

[0088] In terms of the glue application station, the device is provided with two mirror-symmetrical glue application stations, which are located on one side of the feeding mechanism 100. This symmetrical design not only improves the work efficiency of the device, but also makes the glue application process more uniform and consistent.

[0089] In this embodiment, the two glue application stations are mirror-symmetrical about the perpendicular bisector of the moving path of the feeding mechanism 100. The advantage of this is that when the feeding mechanism 100 just moves to both ends of the stroke for feeding, the accuracy will be higher.

[0090] In another embodiment, as long as the two glue application stations are mirror-symmetrical, and the projections of the two glue application stations are on the moving path of the feeding mechanism 100.

[0091] Each glue application station includes a moving platform 400, a jaw assembly 500, and a glue application structure 600. The moving platform 400 can move horizontally in a direction perpendicular to the moving path of the feeding mechanism 100, providing the necessary flexibility for the glue application process.

[0092] As Figure 4 shown, the jaw assembly 500 includes at least two connecting arms 503 arranged in parallel and equidistantly. A first three-jaw cylinder 504 for clamping materials is connected to the side wall of each connecting arm 503. Such a design enables the materials to be stably clamped between the connecting arms 503, providing stable support for the subsequent glue application process.

[0093] As Figure 3 shown, in this embodiment, the jaw assembly 500 includes:

[0094] A sliding platform 501, which moves in a direction perpendicular to the movement of the moving platform 400, can facilitate the docking of the three-jaw cylinder and the rotary clamping mechanism 602. A flexible floating mechanism 502 is also provided between the sliding platform 501 and the moving platform 400 for horizontal floating in the same direction, improving the docking accuracy of the three-jaw cylinder and the rotary clamping mechanism 602;

[0095] Two connecting arms 503 are fixed to the side walls of the sliding platform 501.

[0096] As Figure 4 and Figure 5As shown, the glue - applying structure 600 is the core part of the glue - applying station. It includes a rotary clamping mechanism 602, a glue - injecting mechanism 601, and a squeegee assembly 604. The rotary clamping mechanism 602 faces and docks with the first three - jaw cylinder 504, and is used to fix the material and can drive the material to rotate.

[0097] As Figure 4 and Figure 5 shown, the rotary clamping mechanism 602 includes a fixture for clamping and fixing the material, and the center of the fixture is connected to the drive shaft of the rotating device. Such a design enables the material to rotate evenly during the glue - applying process, thereby improving the uniformity and quality of glue - applying.

[0098] Meanwhile, in this embodiment, the fixtures for fixing the bearings are all clamped from the inner side of the bearings, which is convenient for applying glue to the outer wall of the bearings. Except for the three - jaw cylinder, the clamping methods of other fixtures include negative pressure, magnetic attraction, tensioning, etc. In this embodiment, the magnetic - attraction method is adopted to improve the fixing effect.

[0099] As Figure 4 and Figure 5 shown, the glue - injecting mechanism 601 is located above the rotary clamping mechanism 602 and is used to inject glue in the direction of the material. In this embodiment, the extension line of the glue - injection port of the glue - injecting mechanism 601 is tangent to the outer wall of the material, and it can cooperate with the squeegee assembly 604 to be evenly applied to the material. If the extension line of the glue - injection port of the glue - injecting mechanism 601 is located on the material, it will cause uneven glue - applying on the material. This mechanism can accurately control the flow rate and injection position of the glue to ensure that the glue can be evenly smeared on the outer wall of the material.

[0100] The squeegee assembly 604 includes a squeegee that can be extended and close to the outer wall of the material, and is used to scrape off the excess glue layer on the surface of the material. Such a design not only ensures the uniformity of glue - applying but also avoids waste of glue.

[0101] It is worth mentioning that the projection distance between the feeding mechanism 100 and the glue - applying structure 600 on the same plane is equal to the horizontal linear distance between two adjacent connecting arms 503. Such a design ensures that when one of the three - jaw cylinders clamps the material at the feeding station (i.e., the station where the three - jaw cylinder can just clamp the material on the feeding mechanism 100), the other three - jaw cylinder is just located at the glue - applying station (i.e., the station where the material can be glue - applied) for glue - applying. The movement of the three - jaw cylinder is precisely controlled by the moving platform 400.

[0102] In addition, the frame 200 serves as the supporting structure of the entire device, and the upper end thereof is connected to the stand 300, and the mobile platform 400 is slidably connected to the stand 300 via the second slide rail 401. The frame 200 is also provided with a residual liquid recovery tank 603 for recovering glue directly below the glue injection mechanism 601. Such a design not only avoids the waste of glue, but also protects the working environment.

[0103] Embodiment 2

[0104] In order to further improve the efficiency and uniformity of gluing, each gluing station is equipped with a lifting and grabbing mechanism 700 and a flipping mechanism 800. The lifting and grabbing mechanism 700 includes a fourth cylinder 701 vertically connected to the bottom wall of the mobile platform 400 and a second three-claw cylinder 702 connected to the driving end of the fourth cylinder 701. The lifting and grabbing mechanism 700 and the clamping claw assembly 500 are connected to the lower end of the same mobile platform 400. This design enables the lifting and grabbing mechanism 700 to accurately grab and transplant materials.

[0105] The turning mechanism 800 is located below the moving path of the lifting and grabbing mechanism 700, and its structure includes a turning table 801 that can turn in parallel to the moving direction of the feeding mechanism 100. At least one first fixing fixture 802 that can clamp the material is provided on the turning table 801, and a second photoelectric sensor 803 for detecting the position of the material is also provided on the turning table 801. Such a design enables the necessary turning and positioning of the material during the gluing process, further improving the uniformity and quality of the gluing.

[0106] In this embodiment, Figure 2 As shown, in order to improve the working efficiency and automation of the equipment, a discharging mechanism 900 is also provided; the discharging mechanism 900 is located on the other side of the two gluing stations, and is used to transport the materials coated with glue to the designated position. There is only one discharging mechanism 900, and its moving path covers the two gluing stations, so that the discharging of two materials is completed by one discharging mechanism 900, which is adapted to the rhythm of the feeding mechanism 100, improving the working efficiency and reducing the cost. The discharging mechanism 900 includes a second fixed fixture 903 for docking the material with the lifting and grasping mechanism 700, and the fixture is provided with a sixth cylinder 902 that drives it to move along the moving direction of the lifting and grasping mechanism 700. At the same time, the second fixed fixture 903 is also provided with a fifth cylinder 901 that can drive it to move between the two gluing stations. Such a design enables the materials coated with glue to be automatically transported to the designated position for subsequent equipment to grab and discharge, thereby improving the working efficiency and automation of the equipment.

[0107] At the same time, a third photoelectric sensor is also provided on the side wall of the second clamp 903 for detecting the position of the material, so as to facilitate the subsequent grasping mechanism to carry out accurate material unloading.

[0108] Through precise control at various positions, the utility model realizes precise control of materials, thereby improving the precision of glue application.

[0109] To ensure the stability and precision of the equipment, the projection distance between the lifting and grasping mechanism 700 and the adjacent connecting arm 503 in the same plane is equal to the horizontal distance between two adjacent connecting arms 503. At the same time, the projection distance between the glue application structure 600 and the flipping mechanism 800 in the same plane is also equal to the horizontal distance between two adjacent connecting arms 503. This design ensures the full utilization of the two connecting arms 503. Combining with the projection distance between the feeding mechanism 100 and the glue application structure 600 in the same plane mentioned in Embodiment 1, which is equal to the horizontal linear distance between two adjacent connecting arms 503, when one three-jaw cylinder holds the material at the feeding station, the other three-jaw cylinder is just located at the glue application station for glue application. And when the material at the glue application station is finished with glue application, it is moved to the flipping mechanism 800 by the three-jaw cylinder. After being flipped by the flipping mechanism 800, it is also convenient for the lifting and grasping mechanism 700 to grasp. At the same time, after the lifting and grasping mechanism 700 holds the material, it will also move with the moving platform 400 and convey the material to the discharging mechanism 900. The sixth cylinder 902 provided on the discharging mechanism 900 can coordinate the distance between the second fixed fixture 903 and the lifting and grasping mechanism 700, so as to dock the material well. At the same time, the glued material is conveyed to the designated position by the fifth cylinder 901. Through the precise docking and collaborative work among various components, the overall performance and production efficiency of the equipment are improved.

[0110] Embodiment 3

[0111] On the basis of Embodiment 2, this embodiment further optimizes and improves the scraper assembly 604.

[0112] Specifically, the scraper assembly 604 includes an opening and closing cylinder 6041, a scraper, and a third cylinder 6042. The opening and closing cylinder 6041 is provided with two openable and closable clamping arms, and side plates are connected to both clamping arms. The scraper is fixedly connected to one of the side plates, and it includes a vertically arranged scraper plane 6045 and a scraper inclined plane 6046 arranged at the upper end of the scraper plane 6045.

[0113] According to what is mentioned in the above Embodiment 1, the extension line of the glue injection port of the glue injection mechanism 601 is tangent to the outer wall of the material. Therefore, such a design makes the scraper plane 6045 as close as possible to the outer wall of the material, and the thickness of the glue application can be precisely controlled. In addition, the scraper inclined plane 6046 can temporarily store glue, making the glue application more uniform. At the same time, with rotation, the glue on the material can be made more uniform.

[0114] At the same time, in order to further improve the use effect and life of the scraper, an inner edge block 6047 is connected to the side plate close to the first three-claw cylinder 504. The side wall of the inner edge block 6047 is arranged parallel to the scraper, and the gap between the inner edge block 6047 and the scraper is close to the wall thickness of the material. Such a design enables the scraper to always maintain parallelism with the outer wall of the material during the scraping process, thereby improving the scraping effect and quality.

[0115] First, the distance between the scraper and the material is determined by the third cylinder 6042 to control the thickness of the glue coating, and then the two side plates are brought close to each other through the opening and closing action of the opening and closing cylinder 6041, so that the inner edge block 6047 is stuck to the inner edge of the material. Because the gap between the inner edge block 6047 and the scraper is close to the wall thickness of the material, the amplitude generated when the material rotates will be greatly reduced (because when the material is actually coated with glue, only one side is connected, and jitter will occur when rotating. By clamping the outer edge of the material to improve the quality of the glue coating, it can also ensure that the scraper is always set parallel to the outer wall of the material), thereby improving the stability of the material rotation, and then the accuracy and uniformity of the glue coating can also be improved.

[0116] In addition, the side wall of the side plate between the inner edge block 6047 and the scraper is provided with a groove 6048 extending downward. Such a design can control the shape of the glue forming, so that the side wall of the material can also be coated with glue, overcoming the problem of the traditional glue coating structure and the small glue coating range, and further improving the glue coating range and uniformity.

[0117] Specifically, in this embodiment, Figure 6 As shown, the first side plate 6043 is provided with an inner edge block 6047 and a groove 6048, and the second side plate 6044 is fixedly connected with a scraper, and the side of the inner edge block 604 close to the inner wall of the material is arc-shaped, corresponding to the shape of the inner wall of the material.

[0118] In general, the gluing structure for the outer wall of a bearing provided by the utility model has the advantages of compact structure, simple operation, uniform gluing and high efficiency. Through the coordinated use of the feeding mechanism, the gluing station, the lifting and grabbing mechanism, the flipping mechanism and the discharging mechanism, the automatic gluing process of the outer wall of the bearing is realized, and the production efficiency and product quality are improved. At the same time, by optimizing and improving the scraper assembly, the uniformity and quality of the gluing are further improved.

[0119] At the same time, after being coordinated and controlled by the control system, the utility model can realize automatic loading, gluing, unloading and other processes to improve the overall work efficiency.

[0120] It should be noted that although the embodiments of the present utility model are described by taking bearings as an example, the principle of the present utility model is equally applicable to the outer wall gluing of other materials with similar shapes and sizes. In addition, the present utility model can be further improved and optimized according to actual needs to adapt to different production requirements and application scenarios.

[0121] Improve production efficiency: Through the combination of automation and intelligence, the equipment can continuously and stably perform gluing operations, greatly reducing the need for manual intervention, thereby improving the overall production efficiency.

[0122] Reduce the defective rate: Precise control systems and advanced sensors ensure the accuracy and uniformity of gluing, effectively reducing the defective rate and improving product quality.

[0123] Energy conservation and environmental protection: Through a precise glue control system, unnecessary waste is avoided. At the same time, the equipment fully considers energy consumption during design, adopts energy-saving motors and optimized pneumatic systems, further reducing energy consumption.

[0124] Improve the working environment: The automated gluing process reduces manual operations, thereby reducing the risk of workers being exposed to harmful chemicals and improving the working environment.

[0125] Enhance production flexibility: The modular design and scalability of the equipment enable enterprises to quickly adjust the production line configuration according to needs to cope with the rapid changes in market demand.

[0126] Improve management efficiency: By integrating with the enterprise management system, production data can be obtained in real time, providing decision-making support for management and improving the overall management efficiency.

[0127] In summary, this double-station automated equipment for gluing the outer wall of bearings not only improves production efficiency, reduces costs, but also improves the working environment and enhances product quality, creating great economic value and social value for enterprises. Through continuous technological innovation and optimization, the equipment is expected to bring more significant benefits to bearing production enterprises in the future.
