Description

Technical Field

[0001] The utility model relates to the technical field of mechanical equipment, in particular to a belt synchronous rotation mechanism. Background Art

[0002] Belt synchronous rotation mechanisms are mainly used in various mechanical equipment to ensure the precise synchronization of components within the transmission system.

[0003] Traditional belt drives use friction drive principles, and the transmission belt may slip during the transmission process, which reduces the transmission efficiency. The belt may stretch after long-term use, affecting the transmission accuracy. It needs to be inspected and replaced regularly to prevent failures caused by wear, which increases maintenance costs and downtime. Traditional belt drives are very sensitive to the alignment of the axles and the tension of the belts. Improper alignment or tensioning can lead to premature wear and reduced efficiency.

[0004] The prior art provides a method for realizing stable, precise and efficient transmission of multiple workstations through a synchronous belt mechanism. For example, the utility model patent with the announcement number CN219408231U and the patent name "A synchronous belt rotation mechanism for visual inspection" provides a method that can realize synchronous rotation of multiple workstations and has a high transmission efficiency. However, its overall structure is still not compact enough, and the spacing of the workpiece fixture arrangement still needs to be further optimized. Utility Model Content

Preferably, a secondary tensioning wheel is connected between adjacent driven pulleys on the rotating plate and between the driving pulley and the driven pulley through a synchronous belt.

[0011] In the utility model, maintaining the appropriate tension of the transmission belt is helpful to reduce or prevent the slipping of the belt on the pulley, thereby improving the transmission efficiency and reducing the wear.

[0012] Preferably, the synchronous belt and the driving pulley, the main tensioning pulley and the driven pulley are all meshing transmissions.

[0027] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. It should be understood that the embodiments are only used to explain the utility model but not to limit it.

[0028] Example 1

[0029] like Figure 1-6 As shown, this embodiment provides a multi-station synchronous belt rotation mechanism, including a flip mechanism 341 and a belt synchronous rotation mechanism 342; the flip mechanism 341 includes a flip frame 301 and a support frame 302, and the flip frame 301 includes a driving shaft mounting plate 303 and a driven shaft mounting plate 304; the belt synchronous rotation mechanism includes a rotating plate 246 whose two ends are respectively connected to the driving shaft mounting plate 303 and the driven shaft mounting plate 304, and a rotating drive mechanism, a plurality of product fixtures 247 and a transmission mechanism for driving the product fixture 247 are provided on the rotating plate 246, the rotating drive mechanism includes a rotating servo motor 241, and the transmission mechanism includes a driving pulley 242 and a plurality of driven pulleys 243 connected to the driving pulley 242 through a transmission belt 244 and corresponding to the product fixture 247; the rotation axes of the plurality of driven pulleys 243 are all on a first plane, and the first plane is perpendicular to the width direction and the length direction of the rotating plate 246; the rotation axis of the driving pulley 242 is on a second plane, and the second plane is arranged parallel to the first plane.

[0030] Through this embodiment, combined with the flipping mechanism 341 and the belt synchronous rotation mechanism 342, operations can be performed simultaneously on multiple work stations, greatly improving production efficiency and continuity of workflow. The rotating servo motor 241 provides precise control and synchronization to ensure that multiple product fixtures 247 can maintain synchronization during rotation. It is suitable for occasions that require precise positioning and processing. More work stations can be accommodated under the same length, which has greater advantages when inspecting small-sized workpieces. The axes of multiple driven pulleys 243 are all located on the first plane, while the axis of the driving pulley 242 is located on the second plane. This parallel layout helps to evenly distribute the load and reduce mechanical stress, thereby improving the stability of the overall structure.

[0031] Combination Figure 1-6 As shown, in this embodiment, the support frame 302 includes a support plate 309 and a swing arm mounting plate (308) and a vertical plate 305 installed at both ends of the support plate 309 and perpendicular to the support plate 309; the swing arm mounting plate (308) is provided with a bearing hole for mounting the driven shaft mounting plate 304, and the driven shaft mounting plate 304 and the swing arm mounting plate (308) are connected by a first bearing 316 arranged in the bearing hole; an arc groove 321 is provided around the upper part of the bearing hole on the swing arm mounting plate 308, and a position sensor 311 is provided at both ends and the middle of the arc groove 321, and a positioner 312 cooperating with the position sensor 311 is provided on the outer side of the driven shaft mounting plate 304.

[0032] The support frame 302 in this embodiment includes a support plate 309, and a swing arm mounting plate 308 and a vertical plate 305 mounted at both ends of the support plate and perpendicular to the support plate. This structural design provides a solid support foundation, ensuring the stability and reliability of the entire mechanism. The positioner 312 on the outside of the driven shaft mounting plate is used in conjunction with the position sensor 311 to provide a high-precision positioning system, which helps to accurately control and adjust the position of the driven shaft. The servo motor is connected through a reducer to make the product fixture swing between -90° to 0° to +90°. When the flip mechanism swings to 0°, the positioner cooperates with the positioner in the middle, and when the swing amplitude reaches ±90°, it cooperates with the positioners at the two ends to transmit signals. Through this design, the mechanism can achieve efficient and precise motion control, which is suitable for applications that require precise positioning and high repeatability.

[0033] In this embodiment, the multi-station synchronous belt rotation mechanism is characterized in that it includes a flipping drive mechanism 322, the flipping drive mechanism 322 includes a flipping servo motor 307, the output shaft of the flipping servo motor 307 is connected to the reducer 306, the output shaft of the reducer 306 is connected to the active shaft mounting plate 303 through a second bearing 317, and a photoelectric sensor 313 is provided between the active shaft mounting plate 303 and the reducer 306. The photoelectric sensor 313 includes a photoelectric gate fixed under the second bearing and a shading plate arranged on the side of the second bearing 317, and the shading plate can pass through the photoelectric gate under the rotation of the second bearing.

[0034] The use of the servo motor in this embodiment allows precise control of the speed and angle of the flipping action, which is very suitable for applications requiring high-precision control. The output shaft of the flip servo motor 307 is connected to a reducer. The reducer reduces the output speed of the motor and increases the output torque, making the flipping action smoother and more powerful. The shading plate and the photoelectric gate are used to monitor and confirm the rotational position and state of the active shaft mounting plate. When the shading plate passes through the photoelectric gate, it interrupts or changes the light passing through the photoelectric gate, thereby providing accurate feedback on the rotational position.

[0035] In this embodiment, the rotating mechanism 301 is provided with four reinforcing plates 248 which are perpendicular to the mounting plate 303 and the rotating plate 246, and the flipping drive mechanism 322 is provided with a reducer protection cover 314; the rotating drive mechanism is provided with a rotating servo motor 241 protection cover 331, and the rotating servo motor 241 protection cover 331 is respectively fixed on the driving shaft mounting plate 303 and the rotating plate 246.

[0036] Through this embodiment, the reducer protection cover 314 is configured to protect the reducer from external damage, extend its service life, and provide safety protection, which is a part of the rotating drive mechanism and provides the necessary rotational power. The rotating servo motor 241 protection cover 331 is fixed on the driving shaft mounting plate 303 and the rotating plate 246 to protect the motor from physical damage and external environmental factors, while reducing noise and providing a safety barrier.

[0037] In short, the above is only a preferred embodiment of the present utility model, and all equivalent changes and modifications made according to the scope of the patent application of the present utility model should fall within the scope of the present utility model patent.
