Description
Technical Field
[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to an auxiliary conveying device for a friction line conveying system. Background Technology
[0002] In automotive production lines, friction line conveyor systems are a crucial component of traditional conveying and assembly. Current technologies often employ suspended conveyor lines to assemble workpieces such as car doors. The conveying devices typically use a single chain-driven conveyor belt. Because brief pauses are required between workstations for assembly, this single chain-driven method leads to instability and swaying of the lifting components during transport between workstations. This lack of stable support and power drive causes the lifting components to sway during transport, resulting in insufficient stability, accelerated wear on the conveyor line, and higher maintenance costs.

However, those skilled in the art will understand that many technical details have been provided in the various embodiments of this utility model to facilitate a better understanding of this application. However, the technical solutions claimed in the claims of this application can be implemented even without these technical details and with various variations and modifications based on the following embodiments.
[0025] like Figure 1-2As shown, one embodiment of this utility model relates to an auxiliary conveying device for a friction wire conveying system. It is installed at the bottom of the friction wire conveying system, located between two adjacent workstations in the production line, and is used for auxiliary conveying of workpieces from one workstation to another to improve the stability of workpiece conveying. The auxiliary conveying device includes a frame 10, which includes two side plates 101 arranged parallel to each other along the axial direction. A driving device is fixedly installed on the side plates 101 of the frame 10. The driving device includes a motor 1 and a reducer 2 connected to the output shaft of the motor 1. The output end of the reducer 2 is connected to a transmission shaft 4. The transmission shaft 4 passes through the two side plates 101 and is rotatably connected to the two side plates 101 via bearings. Preferably, the motor 1 is a servo motor with a positioning accuracy ≤0.1mm. The active component includes an active conveying wheel 6 and an active pulley 5 rigidly connected coaxially to the transmission shaft 4. The active conveying wheel 6... The active pulley 5 is located between the two side plates 101; the driven assembly includes a support shaft 7 arranged parallel to the drive shaft 4, with both ends of the support shaft 7 fixed to the two side plates 101, and a driven conveyor wheel 9 and a driven pulley 8 rotatably arranged on the support shaft 7; the active pulley 5 and the driven pulley 8 are connected by a transmission belt 11 to form a belt drive, preferably, the transmission belt 11 is made of polyurethane, which has improved wear resistance and service life of more than 50,000 hours compared to the transmission chain in the prior art; wherein, the active conveyor wheel 6 and the driven conveyor wheel 9 are arranged axially along the frame 10 to form a conveying path. The workpiece is fixed to the lifting assembly. The drive unit drives the active assembly, and the belt drive of the active and driven assemblies enables the lifting assembly to be stably linearly transmitted along the conveying path of the active conveyor wheel 6 and the driven conveyor wheel 9 under the action of friction. The structure is simple and the operation is stable. The auxiliary conveying device supports and transmits the lifting assembly, which improves the stability of the lifting assembly between different work positions. It helps to reduce the wear of the friction line conveying system equipment caused by the swing of the lifting assembly during the conveying process, and can effectively reduce the maintenance cost of the equipment.
[0026] In use, the motor 1 provides driving force to drive the transmission shaft 4 to rotate. The transmission shaft 4 drives the drive pulley 5 and the drive conveyor 6 to rotate synchronously. The drive pulley 5 drives the driven pulley 8 and the driven conveyor 9 to rotate through belt drive. The lifting device assembly is abutted on the top surface of the drive conveyor 6 and the driven conveyor 9. Through friction, the lifting device assembly is driven to move linearly along the axial direction of the frame 10 and is smoothly conveyed to the next work station.
[0027] One embodiment relates to an auxiliary conveying device for a friction-line conveying system. Depending on the conveying distance, at least two sets of driven components are spaced apart along the axial direction of the frame 10. The driven components are located on the same side of the driving components, and the driven pulleys 8 of adjacent driven components are connected in series via a transmission belt 11. Preferably, the center distance between the drive shaft 4 and the adjacent support shaft 7 is 1.5 meters to 3 meters, and the center distance between the adjacent support shafts 7 is also 1.5 meters to 3 meters. By setting multiple sets of driven components, longer-distance transmission can be achieved, meeting the needs of different conveying distances between workstations.
[0028] One embodiment relates to an auxiliary conveying device for a friction wire conveying system, wherein the drive shaft 4 is fixed to the active conveying wheel 6 and the active pulley 5 via keyway fitting or welding; the driven pulley 8 is fixed to the driven conveying wheel 9 via integral molding or welding. The modular design of the active and driven components helps reduce the difficulty of maintenance and replacement, improves replacement efficiency, and allows for replacement of a single active or driven component in less than 10 minutes, effectively reducing equipment maintenance costs.
[0029] One embodiment relates to an auxiliary conveying device for a friction wire conveying system. The reducer 2 is rigidly connected to the side plate 101 of the frame 10 via a torque arm 3. One end of the torque arm 3 has an annular connecting part, which is coaxially arranged with the drive shaft 4 and fixed to the housing of the reducer 2 by bolts. The other end is fixedly connected to the side plate 101 by fasteners. By supporting and fixing the motor 1 and the reducer 2 through the torque arm 3, the torque borne by the reducer 2 is transmitted to the fixedly mounted frame 10, thereby balancing torque changes during operation and enhancing the stability and reliability of the drive device.
