[0002] With the rapid development of the new energy vehicle industry, the parts processing industry faces the dual pressures of increasing production efficiency and reducing costs. The application of automation technology has become key to solving this problem. As a key component of the material conveying system, the automation level of the ring loading and buffering device directly affects the efficiency and stability of the entire production line.

[0003] During the processing of new energy vehicle parts, maintaining production line continuity and efficiency requires material buffering, particularly for ring-shaped parts. This ring loading buffer ensures a stable supply of material during periods of insufficient material or brief line downtime, thus preventing production interruptions. New energy vehicle parts processing demands extremely high production efficiency, especially on high-speed production lines. The stability of the ring loading buffer is crucial; any minor malfunction or fluctuation could cause production line downtime or product quality issues.

[0004] Currently, most of the equipment 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 economic efficiency. In addition, most of the equipment requires complex programming operations, which increases the production cost of the enterprise and brings inconvenience to the enterprise'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. Utility Model Content

[0033] A ring feeding and caching device, such as Figures 1 to 3 As shown, the cache device includes a vibration generator 1, a vibration feeding guide rail 2, a first pneumatic cylinder 3, a second pneumatic cylinder 4, a cache feeding table 5, a ring cache table 6, a cache table moving block 7, a support frame 8 and a moving block guide rail 9, the first pneumatic cylinder, the second pneumatic cylinder, the cache feeding table, the cache table moving block, the support frame and the moving block guide rail are all arranged in the horizontal direction, and the first pneumatic cylinder, the second pneumatic cylinder, the cache feeding table, the ring cache table, the cache table moving block and the moving block guide rail are all connected and arranged on the support frame;

[0034] The vibration generator and the vibration feeding guide rail are both arranged in the longitudinal direction. The vibration feeding guide rail is connected to the vibration generator. The vibration generator can drive the vibration feeding guide rail to vibrate and transport the annular material 10, so that the vibration generator can transmit vibration power to the vibration feeding guide rail, so that the vibration feeding guide rail can feed the material by vibration.

[0035] The movable block guide rail is fixedly mounted on the support frame, and the cache platform moving block is slidably mounted on the moving block guide rail, and the cache platform moving block can slide back and forth in the horizontal direction along the moving block guide rail; a ring cache platform is fixedly mounted above the cache platform moving block and connected thereto; the first pneumatic cylinder is fixedly mounted on the support frame, and the output end of the first pneumatic cylinder is detachably connected to the ring cache platform, and the ring cache platform can drive the cache platform moving block to move back and forth in the horizontal direction along the moving block guide rail under the drive of the first pneumatic cylinder, so that the first pneumatic cylinder can drive the ring cache platform to move to the ring leakage hole of the cache feeding platform, so that the ring material can be accurately set on the ring cache platform after falling off the cache feeding platform;

[0036] The cache feeding platform and the second pneumatic cylinder are both arranged on the support frame above the guide rail of the moving block. The cache feeding platform includes a cache feeding platform body 55, a material cache groove 54 and a ring leak hole 53. The cache feeding platform body is arranged in the horizontal direction.

A ring leakage hole is connected to the cache feeding platform body of the pneumatic cylinder, and the ring leakage hole is arranged opposite to the output end of the second pneumatic cylinder. The output end of the second pneumatic cylinder can push the ring material in the material cache groove toward the ring leakage hole until the ring material leaks downward from the ring leakage hole and falls. The ring leakage hole is arranged in a vertical direction and extends from the upper surface of the cache feeding platform body to the lower bottom surface thereof. The diameter of the ring leakage hole is larger than the diameter of the ring material, so that the ring material can leak downward from the ring leakage hole, which is convenient for the next operation;

[0037] 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 therein into the material buffer groove, so that the output end of the subsequent second pneumatic cylinder pushes the ring material in the material buffer groove toward the ring leakage hole until the ring material leaks downward from the ring leakage hole and falls, and then falls onto the ring buffer table directly below it, so as to facilitate subsequent operations on the material;

[0039] When the material is in a state of being moved, the first pneumatic cylinder drives the moving block of the buffer table to move, so that the ring buffer table on the moving block of the buffer table stops when the ring buffer table is coaxially arranged with the ring leak hole. At this time, the ring buffer table is coaxially arranged just below the ring leak hole, so that the ring falling from the ring leak hole can be accurately fitted on the ring buffer table. When the number of rings on the ring buffer table reaches the cache upper limit of the ring buffer table, the first pneumatic cylinder drives the moving block of the buffer table to make the ring buffer table leave the bottom of the cache feeding table and enter the work of the next process link, and the operation is used in this cycle.

[0040] When in use, this device can be connected to the robotic arm used in the processing of new energy vehicle parts, and can provide the robotic arm with the rings it needs for its work. The utility model drives the vibration feeding guide rail through the vibration generator to realize automatic feeding of the rings, reducing manual operation and improving feeding efficiency.

[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 feed table, facilitating maintenance and component replacement. The device's design also allows for potential future improvements and expansions. By adjusting the relevant parameters of the vibrating feed rail, buffer feed table, and ring buffer table, the device can accommodate rings of varying sizes and types, enhancing versatility and flexibility.

[0043] In this embodiment, the ring loading and caching device also includes an infrared limit detector 61, which is connected and arranged on the support frame.

The diameter of the material leakage through hole is larger than the diameter of the ring material, so that the annular material transported from the longitudinal output end of the vibrating feeding guide rail can be transported into the material leakage through hole; and the material leakage through hole can be arranged above and below the ring leakage hole. 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 horizontally in the material buffer groove. 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, so that the cache feeding platform can reduce the blockage of the ring.

[0046] Preferably, the ring buffer block is detachably connected to the output end of the second pneumatic cylinder to facilitate maintenance and replacement of components.

[0047] Preferably, the cache feeding platform also includes a laser detector 51, which is connected and arranged on the ring cache block.
