Description

Technical Field

[0002] With the rapid development of the new energy vehicle industry, the parts processing industry is facing the dual pressure of improving production efficiency and reducing costs. The application of automation technology has become the key to solving this problem. As an important part of the material conveying system, the automation level of the ring feeding buffer device directly affects the efficiency and stability of the entire production line.

[0003] In the process of processing new energy vehicle parts, in order to maintain the continuity and efficiency of the production line, it is necessary to cache materials, especially some ring-shaped rings. The ring loading cache can provide a stable material supply to the production line when the material supply is insufficient or the production line is temporarily shut down, thereby avoiding production interruptions. The processing of new energy vehicle parts has extremely high requirements for production efficiency on high-speed production lines. The stability of the ring loading cache device is crucial, and any minor faults or fluctuations may cause production line shutdowns or product quality problems.

[0004] Most of the equipment currently on the market uses a robotic arm to perform material loading and caching operations. Although this method can accurately perform material loading and caching operations, the time required for loading is greatly increased. At the same time, due to the use of a robotic arm, the equipment occupies a large area and has poor economy, and most of them require complex programming operations, which increases the company's production costs and brings inconvenience to the company's production.

[0005] Therefore, it is urgent to design one or several new ring feeding and buffering devices to ensure the continuous operation of the production line. Summary of the invention

[0012] One longitudinal end of the vibrating feeding guide rail is extended into the material buffer groove, and the vibrating feeding guide rail can convey the annular material transported inside the vibrating feeding guide rail into the material buffer groove;

[0013] The ring cache table is arranged in the vertical direction and is arranged as a cylinder. The ring cache table can be coaxially arranged directly below the ring leakage hole of the cache feeding table. The diameter of the ring cache table is smaller than the diameter of the ring material.

[0024] 2. The buffer table moving block of the device is detachably connected to the ring buffer table, which is convenient for maintenance and replacement of parts.

By adjusting the relevant parameters of the vibrating feeding guide rail, the buffer feeding table and the ring buffer table, the device can adapt to rings of different sizes and types, improving versatility and flexibility.

[0025] 3.

At the same time, the first pneumatic cylinder pneumatically drives the cache table moving block to move, so that the ring cache table on the cache table moving block stops when it is coaxially arranged with the ring leakage hole. At this time, the ring cache table is coaxially arranged directly below the ring leakage hole, so that the ring falling from the ring leakage hole can be accurately mounted on the ring cache table.

[0040] When in use, this device can be connected to a mechanical arm during the processing of new energy vehicle parts, and can provide the mechanical arm with the rings required for its work. The present invention drives the vibration feeding guide rail through a vibration generator to realize automatic feeding of the rings, reduce manual operation, and improve feeding efficiency. When the material supply is insufficient or the production line is temporarily shut down, the buffer feeding table and the ring buffer table can provide a stable material supply for the production line, avoid production interruptions, and ensure the continuity and efficiency of the production line. The overall structure of this device is compact, easy to operate and use, and easy to integrate into existing production lines, reducing the cost and difficulty of transformation, shortening the time required for loading, reducing the large floor area, reducing the production cost of the enterprise, and bringing convenience to the production of the enterprise.

[0042] In this embodiment, the buffer table moving block is detachably connected to the ring buffer table, and the output end of the second pneumatic cylinder is detachably fixedly connected to the buffer feeding table, which is convenient for maintenance and replacement of parts. At the same time, the design of the device also provides space for possible subsequent improvements and expansions.

The coaxial arrangement enables the material in the material leakage through hole to leak downward from the material leakage through hole and fall into the ring leakage hole, and then leak downward from the ring leakage hole and fall; the ring buffer block is connected to the output end of the second pneumatic cylinder, and the output end of the second pneumatic cylinder can drive the ring buffer block to move back and forth in the material buffer groove along the horizontal direction. When the material leakage through hole can be coaxially arranged with the ring leakage hole above and below, the material in the material leakage through hole can leak downward from the ring leakage hole and fall, so that the cache feeding table can reduce the blockage of the ring.
