Description

Technical Field

[0001] This utility model relates to the field of material handling mechanism technology, and in particular to a hollow rotary material handling mechanism. Background Technology

[0002] In the field of automated manufacturing, especially in precision workpiece machining, rotary reversing conveying mechanisms, as core modules connecting different process stages, directly determine production efficiency and product quality through their positioning accuracy and motion continuity. However, existing rotary reversing conveying modules generally suffer from insufficient accuracy and poor stability, making it difficult to meet the demands of modern high-precision, high-cycle manufacturing. Specific technical deficiencies are as follows:

[0003] The workpiece rotation and reversing conveying module and the rotating indexing plate have minute gaps in their mechanical structure. Long-term high-frequency operation causes wear and leads to deviations in indexing accuracy. The mechanical gripper has a slow opening and closing control response and coarse gripping force adjustment. Different workpieces are prone to unstable gripping and slippage, interfering with the accuracy of conveying. Modern manufacturing has high requirements for workpiece processing accuracy and flow continuity. Because the existing rotation and reversing links cannot achieve high precision, workpiece transmission deviations and pauses occur, making it impossible to adapt to subsequent processes and hindering production. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a hollow rotary conveying mechanism.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Preferably, a feeding conveyor and a discharging conveyor are respectively provided on both sides of the support.

[0008] Preferably, both the feeding conveyor and the discharging conveyor are belt conveyors.

[0009] Preferably, the vacuum turntable includes a turntable connected to the drive end of the lifting drive device and several vacuum plates fixedly connected to the top periphery of the turntable. The vacuum suction cup is fixedly installed at the bottom of the vacuum plate and communicates with the inner cavity of the vacuum plate.

[0010] Preferably, a plurality of the vacuum plates are arranged in a ring array on the top periphery of the turntable.

[0011] Preferably, one side of the bracket is provided with a column fixedly installed on the base, the column is hollow, and the vacuum pump is installed inside the column.

[0012] Preferably, the lifting drive device is a cylinder.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] This invention replaces the traditional rotary indexing plate with a hollow rotary platform. A servo motor ensures power transmission and control of the hollow rotary platform, while a vacuum suction cup enables stable gripping of different workpieces. This solves the problems in the prior art, such as the workpiece rotation and reversing transport module and the rotary indexing plate having small gaps in their mechanical structure, wear caused by long-term high-frequency operation, resulting in deviations in indexing accuracy, slow response of mechanical gripper opening and closing control, coarse gripping force adjustment, and unstable gripping and slippage of different workpieces, which interfere with the accuracy of transport.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1 and Figure 2 A hollow rotary conveying mechanism includes a base 1, a bracket 2 mounted on the top of the base 1, a rotary drive device 3 mounted on the bracket 2, the rotary drive device 3 being a servo motor, the drive end of the rotary drive device 3 movably passing through a turntable mounted on the top of the bracket 2, a lifting drive device 5 mounted on the top of the turntable, a vacuum turntable mounted on the lifting drive device 5, and a plurality of vacuum suction cups 7 mounted on the outer end of the top of the vacuum turntable, the vacuum suction cups 7 being connected to a vacuum pump through pipelines.

[0023] The hollow rotary platform replaces the traditional rotary indexing plate. A servo motor ensures power transmission and control of the hollow rotary platform, while the vacuum suction cup 7 enables stable gripping of different workpieces. The connection with the feeding conveyor 14 and the discharging conveyor 15 is smoother, and the workpiece feeding, handling, and discharging are seamless and stable, improving production efficiency and stability. There are no problems of jamming, collision, or accumulation, creating a highly efficient and reliable production environment. This solves the problems in the existing technology, such as the workpiece rotation and reversing handling module and the mechanical structure of the rotary indexing plate having small gaps, wear caused by long-term high-frequency operation, resulting in indexing accuracy deviation, slow response of mechanical gripper opening and closing control, coarse gripping force adjustment, and easy instability and slippage of different workpieces, which interfere with the accuracy of handling.

[0024] In this embodiment, a feeding conveyor 14 and a discharging conveyor 15 are respectively provided on both sides of the support 2. Both the feeding conveyor 14 and the discharging conveyor 15 are belt conveyors. Adjustable feet 10 are installed at the four corners of the bottom of the feeding conveyor 14 and the discharging conveyor 15. The adjustable feet 10 are adjusted by threads to adjust the height according to the workpiece parameters. The height difference at the feeding end is controlled to achieve smooth handover. The height at the discharging end is adapted to prevent the workpiece from slipping. A buffer pad is provided at the bottom of the adjustable feet 10, and the buffer pad is made of rubber.

[0025] In this embodiment, the vacuum turntable includes a turntable 6 connected to the driving end of the lifting drive device 5 and several vacuum plates 9 fixedly connected to the top periphery of the turntable 6. The vacuum suction cup 7 is fixedly installed at the bottom of the vacuum plate 9 and communicates with the inner cavity of the vacuum plate 9. The vacuum pump creates a negative pressure on the vacuum plate 9 and the vacuum suction cup 7 through the pipeline to achieve adsorption of the workpiece. The way the vacuum suction cup 7 is installed on the vacuum plate 9 allows multiple vacuum suction cups 7 to be installed on one vacuum plate 9 at the same time.

[0026] In this embodiment, several vacuum plates 9 are arranged in a ring array on the top periphery of the turntable 6.

[0027] In this embodiment, a column 8 is fixedly installed on the base 1 on one side of the bracket 2. The column 8 is hollow, and the vacuum pump is installed inside the column 8 (the location of the vacuum pump is not shown in the figure), which facilitates the arrangement of the vacuum pump and pipeline.

[0028] In this embodiment, the lifting drive device 5 is a cylinder.

[0029] In this embodiment, a mounting base 11 is installed on the top side of the column 8, and a support column 12 is installed at the end of the mounting base 11 away from the column 8. A rotating ring 13 is rotatably installed at the bottom of the support column 12. The bottom of the rotating ring 13 is fixedly connected to the top of the turntable 6 through a connecting rod 4, which facilitates limiting the top of the turntable 6 and improves the accuracy of the rotation position.

[0030] Additionally, it should be noted that the servo motor in this device is not controlled to rotate in one direction continuously, but can rotate one revolution forward and one revolution backward to prevent damage to the wiring and pipes.

[0031] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
