Description

Technical Field

[0001] The invention relates to the technical field of gluing, and in particular to a sleeve gluing device. Background Art

[0002] In the field of automotive parts, rubber bushings play a vital role. They can effectively buffer vibrations, reduce noise, and improve driving comfort and stability. Among them, the structural design of a considerable number of rubber bushings requires the installation of bushing inner tubes to enhance the overall performance. In the actual production and assembly process, one of the key processes is to apply glue to the outer circumference of the bushing inner tube and then install the rubber bushing. Since a very stable adhesion effect must be formed between the rubber bushing and the bushing inner tube to ensure that there will be no loosening, displacement and other problems under the complex operating conditions of the car, the two-time gluing process is currently commonly used.

[0003] However, the traditional manual gluing method has exposed many drawbacks. On the one hand, workers hold the gluing tools and can only apply glue to a single bushing inner tube at a time. This one-to-one operation mode is extremely inefficient and far from meeting the needs of large-scale and mass production in the modern automobile industry. Summary of the invention

[0004] In view of the shortcomings of the above-mentioned prior art, the present invention provides a sleeve gluing device to solve a series of problems faced by traditional gluing, such as low efficiency and long secondary gluing time, meet the needs of modern industry for high-quality and large-scale production of sleeve gluing, improve the product gluing process level, and reduce production costs and maintenance difficulty.

[0007] Frame;

[0008] The conveyor chain assembly includes a conveyor chain, a toothed disc and a driving end. The conveyor chain is arranged on one side of the frame and forms a circulation path through the toothed disc. One toothed disc drives the conveyor chain to circulate through a drive installed on the frame.

[0009] The hanging assembly includes a hanging rod and a placing rod. One end of the hanging rod can be rotatably hung on the conveying chain and can move with the conveying chain. The placing rod is horizontally arranged at the other end of the hanging rod and is used to hang the sleeve to be coated with glue.

[0010] The glue coating assembly is provided in two groups, each group of the glue coating assembly includes a roller brush, a glue bucket and a driving device, the roller brush can be rotatably arranged on the glue bucket, and is driven to rotate by the driving device on one side of the glue bucket; the glue bucket contains glue, and the height of the glue ensures that it contacts the roller brush; the glue coating assemblies are arranged side by side on the circulation path of the conveyor chain at intervals, and are at the same distance from the conveyor chain, and are located below the toothed disc, and the height of the roller brush is higher than the lowest height when the placement rod passes through the glue coating assembly, so that the sleeve can contact the roller brush to complete the glue coating operation; the direction of rotation of the roller is opposite to the direction of movement of the conveyor chain;

[0011] The drying component is installed on the frame, and the conveying chain component is arranged between the drying component and the frame.

[0012] Furthermore, in the above scheme, the conveying chain is a double-row chain structure, and the toothed disc corresponds to the double-row chain structure.

[0013] Furthermore, in the above scheme, the conveyor chain passes through the gluing assembly and the moving direction of the conveyor chain is reversed by a toothed disc.

[0014] In the above scheme, the drying component is a hot air drying component or an electric heating wire drying component.

[0015] Furthermore, in the above scheme, both sets of glue coating components are connected to a driving device, and the driving device is connected to the roller brush of the glue coating component through a gear set to drive the roller brush to rotate.

[0019] Furthermore, in the above scheme, a plurality of supporting toothed discs are provided on the frame along the conveying chain, and the supporting toothed discs are arranged at intervals to support the conveying chain.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention improves production efficiency. Compared with traditional manual single gluing, it can realize cyclic gluing and complete two gluing requirements in one process, thereby increasing the amount of gluing per unit time and meeting the demand for rubber bushings in large-scale and batch production of the modern automobile industry.

[0028] The following is a further detailed description of the embodiments of the invention in conjunction with the accompanying drawings to make the objectives, technical solutions and technical effects of the invention more clearly presented.

[0029] like Figure 1-4 As shown, the present invention discloses a sleeve gluing device, including a frame, a conveyor chain assembly, a suspension assembly and a gluing assembly. In the following embodiments, the sleeve can also be a bushing inner tube, and other similar workpieces that require an outer circle need to be glued.

[0030] The frame is used as a mounting frame for the conveyor chain assembly and can be constructed using profiles.

[0031] The conveyor chain assembly includes a conveyor chain 1, a toothed disc 2 and a driving end. The conveyor chain 1 is arranged on one side of the frame and forms a circulation path through the toothed disc 2. One toothed disc 2 drives the conveyor chain 1 to circulate through a drive installed on the frame.

[0032] The hanging assembly includes a hanging rod 3 and a placing rod 4. The hanging rod 3 can be rotatably suspended on the conveying chain 1 at one end and can move with the conveying chain 1. The placing rod 4 is horizontally arranged at the other end of the hanging rod 3 for hanging the sleeve to be coated with glue. The hanging rod 3 can be provided with a plurality of screw holes 5 for installing the placing rod 4, so as to facilitate the adjustment and installation of the placing rod 4; the screw holes 5 are evenly arranged along the length direction of the hanging rod 3.

[0033] Two groups of gluing components are provided, each group of gluing components includes a roller brush 6, a glue bucket 7 and a driving device, the roller brush 6 can be rotatably arranged on the glue bucket 7, and is driven to rotate by the driving device on one side of the glue bucket 7; the glue bucket 7 contains glue, and the glue height ensures contact with the roller brush 6; the gluing components are arranged side by side on the circulation path of the conveyor chain 1 at intervals, and are at the same distance from the conveyor chain 1, and are located below the toothed disc 2, and the height of the roller brush 6 is higher than the lowest height when the placement rod 4 passes through the gluing component, so that the sleeve can contact with the roller brush 6 to complete the gluing operation; the rotation direction of the roller is opposite to the moving direction of the conveyor chain 1;

[0034] The drying component 9 is installed on the frame, and the conveyor chain component is arranged between the drying component 9 and the frame. The drying component 9 is used to dry the sleeve after glue coating. Specifically, the drying component 9 is a hot air drying component or an electric heating wire drying component, more specifically a drying frame.

[0035] Here, in order to enhance the carrying capacity of the conveyor chain 1 so that it can more stably convey the suspension assembly with the sleeve, the conveyor chain 1 is a double-row chain structure, and the toothed disc 2 corresponds to the double-row chain structure. In order to further enhance the stability of the conveyor chain 1 during operation, a plurality of supporting toothed discs 8 are provided along the conveyor chain 1 on the frame, and the supporting toothed discs 8 are arranged at intervals to support the conveyor chain 1.

[0036] In order to allow the sleeve to fully contact and separate from the roller brush 6 on multiple sides when passing through the gluing assembly, and to ensure that all parts of the sleeve can be evenly coated with glue; the conveyor chain 1 is reversed in its moving direction through the toothed disc 2 when passing through the gluing assembly. During operation, as the sleeve approaches the roller brush 6, the hanging rod 3 can rotate relative to the conveyor chain 1, that is, because of the gravity of the hanging rod 3 and the placement rod 4, as the conveyor chain 1 moves, the sleeve will fit the roller brush 6 and be driven by the roller brush 6 to evenly coat the glue; after the sleeve is at the highest position of the roller brush 6, if it continues to move horizontally, at a certain point in time, the sleeve separates from the roller brush 6, but at this time the sleeve is not at the lowest position, that is, under the action of the gravity of the hanging rod 3 and the placement rod 4, when it separates from the roller brush 6, the sleeve will swing left and right with the hanging rod 3, which may cause a second contact with the roller brush 6 or uneven glue distribution due to shaking. Therefore, after the sleeve is located at the highest position of the roller brush 6, the sleeve is further lifted. Specifically, the conveyor chain 1 passes through the gluing assembly and the toothed disc 2 is used to reverse the moving direction of the conveyor chain 1. Here, the toothed disc 2 is a large toothed disc, which needs to be able to avoid interference between the rollers.

[0037] Here, both sets of glue coating components are connected to the driving device, which drives the roller brush 6 of the glue coating component to rotate through a gear set. Firstly, it reduces the power components, and secondly, it allows the glue coating thickness and uniformity to be more finely controlled.

[0038] In order to optimize the spatial layout of the device, centrally manage the gluing process, and facilitate maintenance and debugging of the gluing components, the gluing components are arranged on the same bottom surface at one end of the frame.

[0039] In order to extend the residence time of the sleeve in the gluing area, the sleeve can be dried after gluing once, so as to facilitate the second gluing; the conveyor chain 1 is provided with a horizontal return section between the two gluing components. The conveyor chain is provided with a loading section, which is located outside the drying component 9; the loading section is used for manual loading and unloading operations.

[0040] When the above scheme is working: first, hang the sleeve to be coated with glue on the placement rod 4 of the hanging assembly, start the device, and the driving end of the conveyor chain assembly drives the toothed disc 2 to drive the double-row conveyor chain 1 to move in a circular motion, and send the sleeve to the gluing assembly area. When the sleeve reaches the gluing assembly, due to the reversal of the moving direction of the conveyor chain 1 and the horizontal return design, the sleeve contacts the high-speed rotating roller brush 6 on multiple sides to complete the gluing. After the first gluing, the sleeve returns with the conveyor chain 1, and the conveyor chain 1 is basically in the drying area throughout the whole process. The hot air drying or electric heating wire drying assembly can quickly remove moisture and solidify the glue; then enter the secondary gluing process. During the whole process, the operator can change the speed of the roller brush 6 through the gear set by adjusting the driving device according to product requirements, adjust the gluing parameters as needed, and can conveniently maintain the gluing assembly located on the bottom surface of one end of the frame.

[0041] The above description is only a preferred feasible embodiment of the present invention and is not intended to limit the scope of the patent application of the present invention. All equivalent changes, equivalent substitutions or modified changes performed within the technical spirit and principles suggested by the present invention should be included in the scope of patent protection covered by the present invention.
