Description

Technical Field

[0001] This utility model belongs to the field of bicycle assembly technology, specifically relating to a bicycle assembly line. Background Technology

[0002] In the bicycle manufacturing industry, the assembly process faces multiple challenges. On the one hand, bicycle parts are diverse and vary significantly in shape. The installation requirements for components such as wheels, handlebars, and chains differ, involving a large number of diverse and specialized installation tools. The classification, retrieval, and circulation of these parts and tools are cumbersome and error-prone in terms of practical operation and spatial layout coordination, severely impacting assembly efficiency. On the other hand, bicycle frames (especially those of electric bicycles with motors, batteries, and other components already installed) are typically large and weigh 15-20 kg, making manual handling and assembly extremely labor-intensive. During frequent transfers, it is not only difficult to ensure the positioning accuracy of the frame and parts but also easy to cause scratches on the frame paint. This is time-consuming, labor-intensive, and prone to product quality problems, hindering the stability and economy of large-scale production. Utility Model Content

Detailed Implementation

[0023] The present invention is further illustrated by the following embodiments, which are intended to more clearly illustrate the technical solution of the present invention, and should not be construed as a limitation.

[0024] An embodiment discloses a bicycle assembly line, the structure of which is as follows: Figures 1 to 9 As shown, it is mainly used for continuous assembly operations where different bicycle parts are installed onto the bicycle frame assembly at different workstations.

[0025] The bicycle assembly line includes a long, narrow workbench 1 and a canopy 2 above the workbench 1. The workbench 1, serving as the main load-bearing structure for assembly operations, has a support frame 11 and a circulating conveyor chain 12. The support frame 11 provides stable support for the overall structure, and the circulating conveyor chain 12 is mounted on the support frame 11 and operates in a closed loop, meaning the circulating conveyor chain 12 can continuously circulate along the closed path formed by the support frame 11, thereby achieving the cyclical transport of materials.

[0026] To facilitate the transfer and positioning of bicycle frame assemblies, multiple supports 9 are spaced apart on the circulating conveyor chain 12. These supports 9 move synchronously with the operation of the circulating conveyor chain 12. The supports 9 are used to fix the bicycle frame assemblies, ensuring their stability during transport and assembly. Each support 9 includes a fixed rod 91, a groove block 92, a swing block 93, and a support rod 94. The fixed rod 91 serves as a basic connecting component, its bottom mounted on the circulating conveyor chain 12, and its top connected to the groove block 92. The groove block 92 has a groove, and the swing block 93 is pivotally mounted within this groove, allowing it to rotate relative to the groove block 92 around its pivot axis. The support rod 94 is fixed to the swing block 93 and directly engages with the bicycle frame assembly for fixation. Simultaneously, the bottom of the groove block 92 has a limiting support surface 921, which forms a limiting engagement with the surface of the swing block 93.

[0027] Multiple workstations are sequentially arranged along the running path of the circulating conveyor chain 12. When the circulating conveyor chain 12 drives the support 9 and the frame assembly, the frame assembly will pass through each workstation in sequence. The operator at each workstation can perform specific component assembly operations (such as installing wheels, handlebars, chains, etc.) on the frame assembly that has moved to that workstation. Through continuous and orderly division of labor and cooperation, efficient assembly is achieved, reducing assembly errors at each workstation.

[0028] As described above, in this bicycle assembly line, the long strip workbench 1 cooperates with the closed-loop circulating conveyor chain 12 to realize the continuous transfer of bicycle frame components. With multiple sequentially arranged workstations, a streamlined operation mode can be formed, which greatly improves assembly efficiency. The support 9, through the pivotal cooperation between the swing block 93 and the groove block 92 and the limiting function of the limiting support surface 921, can not only firmly fix the frame components, but also has adjustability. The canopy 2 is located above the workbench 1, which can reduce dust falling and provide a more stable environment for assembly operations.

[0029] In some preferred embodiments, the outer periphery of the swing block 93 is sequentially provided with a first limiting side surface 931, a first transition surface 932, a limiting bottom surface 933, a second transition surface 934, and a second limiting side surface 935; the first transition surface 932 connects the first limiting side surface 931 and the limiting bottom surface 933, and the second transition surface 934 connects the limiting bottom surface 933 and the second limiting side surface 935. When the swing block 93 rotates about its pivot axis, the limiting support surface 921 of the slot block 92 selectively engages with the first limiting side surface 931, the limiting bottom surface 933, or the second limiting side surface 935 to fix the support rod 94 at the corresponding angle. When the limiting support surface 921 is in contact with the limiting bottom surface 933, the support rod 94 is fixed in the most commonly used vertical state; when the limiting support surface 921 is in contact with the first limiting side surface 931, the support rod 94 is at the first preset angle; when the limiting support surface 921 is in contact with the second limiting side surface 935, the support rod 94 is at the second preset angle.

[0030] In some preferred embodiments, the angle between the first limiting side surface 931 and the limiting bottom surface 933 is 90±5°, and the angle between the limiting bottom surface 933 and the second limiting side surface 935 is 90±5°; the first transition surface 932 and the second transition surface 934 are both arc transition surfaces.

[0031] The specific structure of the circulating conveyor chain 12 includes sprockets 121, chain links 122, and chain plates 124. Sprockets 121 are rotatably mounted at both ends of the support 11. Multiple chain links 122 are connected end-to-end to form a closed chain, driven by the sprockets 121. Chain plates 124 are mounted on the chain links 122 and move synchronously with them. The bottom of the fixing rod 91 of the support 9 is mounted on the chain plate 124, thus moving together with the circulating conveyor chain 12. To drive the circulating conveyor chain 12, at least one sprocket 121 is powered by a drive motor. When the drive motor operates, it drives the sprocket 121 to rotate, thereby driving the entire circulating conveyor chain 12 to operate in a closed loop through the meshing of the sprockets 121 and the chain links 122.

[0032] In some preferred embodiments, tracks 111 are provided on both sides of the support 11 along the running path of the circulating conveyor chain 12. The tracks 111 have a bearing bottom surface 1111 and a limiting sidewall 1112 perpendicular to the bearing bottom surface 1111. The circulating conveyor chain 12 is constrained between the limiting sidewalls 1112 of the two tracks 111. The limiting sidewalls 1112 can prevent the circulating conveyor chain 12 from shifting laterally during operation, ensuring that it travels along a preset path. At the same time, support rollers 123 are installed on the pivot shafts of adjacent links 122 in the circulating conveyor chain 12. The bottom of the support rollers 123 contacts and supports the bearing bottom surface 1111 of the track 111, and rolls on the bearing bottom surface 1111 as the links 122 run. The limiting sidewall 1112 effectively restricts the lateral sway of the circulating conveyor chain 12, improving operational stability; the supporting roller 123 cooperates with the bearing bottom surface 1111 to share the weight of the circulating conveyor chain 12 and the upper support and frame assembly, reducing sway and making the operation of the circulating conveyor chain 12 smoother.

[0033] In some preferred embodiments, side cover plates 112 are also provided on both sides of the bracket 11. The side cover plates 112 extend along the length of the circulating conveyor chain 12 and are located below the edge of the chain plate 124. A vertical gap is left between the side cover plate 112 and the chain plate 124, preferably 2-10mm. This gap can prevent frictional interference between the side cover plate 112 and the chain plate 124 during operation. The side cover plate 112 can prevent external dust and debris from falling into the interior of the circulating conveyor chain 12 or the connection between the chain plate 124 and the chain link 122, reducing the impact of contaminants on the transmission structure. At the same time, its blocking of the edge gap of the chain plate 124 can reduce the risk of operators contacting the moving parts inside the circulating conveyor chain 12, improving the safety of the assembly line.

[0034] In some preferred embodiments, a plurality of lighting sources 21 are installed at the bottom of the canopy 2. These lighting sources 21 are evenly spaced along the running path of the circulating conveyor chain 12, and each workstation is provided with at least one lighting source 21 to ensure that the workstation area receives sufficient illumination.

[0035] In some preferred embodiments, the ceiling 2 is also provided with a power air pipe 22, which extends along the length of the ceiling 2 and is parallel to the running path of the circulating conveyor chain 12. The power air pipe 22 is provided with multiple air supply ports at intervals, each corresponding to a different workstation, for connecting to assembly tools (such as pneumatic wrenches) at the workstation and providing them with a continuous power air source.

[0036] The above embodiments are exemplary and are intended to illustrate the technical concept and features of this utility model, so that those skilled in the art can understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
