Description

Technical Field

[0001] This utility model relates to the field of cyclic transmission technology, and in particular to a multi-station synchronous belt cyclic transmission device. Background Technology

[0002] In the field of multi-station circulating conveyor in automated production lines, multi-station conveyor devices are core equipment for realizing continuous workpiece processing and improving production efficiency. Their performance directly affects the stability, adaptability, and maintenance costs of the production line. However, existing multi-station circulating conveyor devices generally have the following problems that need to be solved: First, existing multi-station circulating conveyor devices generally adopt a separate assembly mode for the conveyor mechanism and the support frame, relying on multiple sets of fasteners for through-fixing. The installation process requires repeated calibration to ensure accuracy, and the disassembly and assembly process is cumbersome and prone to misalignment of the positioning reference due to fastener removal. The protective structure is mostly a monolithic fixed design, which cannot be disassembled according to workstation adjustments, changes in workpiece specifications, or local maintenance needs. This not only results in insufficient adaptability but also increases the space required during transportation and storage. Firstly, the traditional equipment suffers from several drawbacks. The enclosed structure and complex disassembly / assembly processes result in poor maintenance of internal transmission and guiding components, significantly impacting the overall operational efficiency of the production line. Secondly, the transmission system and guiding structure of traditional equipment are often independently designed, relying on a single meshing or friction transmission method for power transmission. This easily leads to problems such as power slippage and lag, resulting in poor synchronization of movement between workstations. The guiding structure often adopts a single-sided constraint design, posing a risk of lateral offset and making it difficult to guarantee stable positioning accuracy. Furthermore, the connection between the workstation and the transmission mechanism is fixed, often using an integrated or multi-fastener structure. When facing the flexible production needs of small-batch, multi-variety production, the entire workstation needs to be replaced or complex disassembly / assembly is required, resulting in insufficient flexibility and an inability to meet the dynamic adjustment needs of modern production lines.

[0009] As a further technical solution of this utility model, fixing buckles are fixedly connected to the arc-shaped inner walls of the left inner ring guard plate and the right inner ring guard plate, and mounting buckle grooves are opened on the middle guard plate corresponding to the positions of the fixing buckles.

At the same time, local protective plates can be disassembled for component inspection, effectively balancing the integrity of protection and the convenience of operation and maintenance. The device's flexibility solves the compatibility and maintenance efficiency problems caused by the rigid structure of traditional devices. Furthermore, it employs a collaborative mechanism of inner ring meshing transmission and outer ring clamping guidance. Precise meshing between the gear disc and the inner ring moving belt ensures stable power transmission, while the clamping guidance of the outer ring guide belt by double-sided rollers creates bidirectional constraints, significantly improving transmission synchronization and positioning accuracy. The workstation uses a snap-fit ​​design for the quick-change base and guide base, allowing for tool-free assembly and disassembly. Different workpiece specifications can be adapted by replacing the quick-change base or customized fixture plate, enabling rapid changeover and perfectly matching the flexible production needs of small-batch, multi-variety production, significantly improving the adaptability and production efficiency of the production line.

The outer ring annular guard plate 15 is fixed by engaging the annular retaining edge 16 with the annular side groove 17, achieving outer ring protection.

[0017] Working Principle: Using this invention, firstly, a support 1 is used as the overall supporting base, on which a workbench 2 is fixedly installed. The workbench 2 has a pre-set tabletop embedding cavity 3 for embedding the embedded transmission mechanism 4. During assembly, the base frame 401 of the embedded transmission mechanism 4 is aligned with the tabletop embedding cavity 3, so that the embedding block 5 on the workbench 2 is precisely engaged into the embedding slot 402 of the base frame 401, completing the initial positioning of the embedded transmission mechanism 4 and the workbench 2, ensuring the overall installation accuracy of the transmission mechanism to avoid subsequent transmission offset. Then, the protective structure is assembled. The embedding plate 8 at the bottom of the middle protective plate 7 is engaged into the groove 6 of the embedding block 5 to fix the middle protective plate 7. Then, the fixing buckles 11 on the arc-shaped inner walls of the left inner ring protective plate 9 and the right inner ring protective plate 10 are correspondingly engaged into the middle... The mounting slot 12 of the inner guard plate 7 is used to simultaneously engage the connecting buckle 14 and the connecting slot 13 at the connection ends of the two to complete the inner ring protection splicing. Finally, the annular side groove 17 on the outer bottom of the outer ring guard plate 15 is aligned with the annular edge 16 of the worktable 2 and secured, forming a double-layer protection to isolate external dust and debris from interfering with the transmission mechanism. According to the specifications of the workpiece to be transmitted, the adaptable quick-change base 416 is snapped onto the guide base 404, achieving quick assembly and disassembly through snap-fit, meeting the adaptation requirements of different workpieces. After the device is started, the output end of the rotating motor 410 transmits torque to the connecting column 409 through the coupling 411. The fixing bracket 412 on the outer side of the coupling 411 is fixed to the bottom outer surface of the base frame 401 to stabilize the coupling 411. To prevent radial offset during power transmission, the top of the connecting column 409 is connected to the gear disk 408, causing the gear disk 408 to rotate within the connecting grooves 407 at both ends of the base frame 401. The gear disk 408 meshes with the lower inner tooth groove 414 on the inner side of the annular inner ring moving belt 413. During rotation, the meshing of the tooth grooves drives the annular inner ring moving belt 413 to circulate. The upper mounting groove 415 on the annular inner ring moving belt 413 engages with the mounting seat 406 on one side of the guide base 404, so that the circulatory movement of the annular inner ring moving belt 413 can synchronously drive the guide base 404 to move. The bottom of the guide base 404 is provided with double-sided rollers 405 corresponding to the position of the annular outer ring guide belt 403. The double-sided rollers 405 clamp the annular outer ring guide belt 403. On both sides, as the guide base 404 moves under the drive of the inner annular moving belt 413, the double rollers 405 roll along the outer annular guide belt 403. This not only restricts the movement path of the guide base 404 through the annular trajectory of the outer annular guide belt 403 to achieve cyclic transmission, but also prevents the guide base 404 from lateral deviation during transmission through a clamping design, ensuring stable movement. As the guide base 404 moves cyclically, the adapter quick-change base 416 and the workpiece fixture it carries pass through each station in sequence, completing the multi-station workpiece transmission operation. During continuous operation of the device, the protective structure formed by the middle guard plate 7, the left inner annular guard plate 9, the right inner annular guard plate 10, and the outer annular guard plate 15 continuously protects the internal transmission components and guide components.To reduce wear and contamination, if the workpiece specification needs to be changed, the quick-change base 416 can be directly disassembled and the corresponding model replaced without disassembling the guide base 404. If internal components need maintenance, the outer annular guard plate 15, the left inner annular guard plate 9, the right inner annular guard plate 10, and the central guard plate 7 can be disassembled sequentially, or the embedded transmission mechanism 4 can be directly removed from the table's embedded cavity 3. This convenient operation does not damage the overall positioning reference, ensuring long-term stable operation of the device.
