Description

Technical Field

[0001] This invention relates to the technical field of feeding devices for automobile production lines, and more particularly to a double-layer automatic feeding device for automobile parts. Background Technology

[0002] Currently, with increasingly faster production cycles in the automotive industry, manual loading methods are no longer adequate for the high-paced production. Furthermore, most automotive parts are irregularly shaped welded components, making loading and unloading difficult and hindering efficient operation. While the trend towards automation and intelligence is becoming increasingly apparent, the unpredictable nature of automotive parts makes automated loading a critical challenge for current intelligent manufacturing processes.

[0003] A Chinese invention patent application with patent number 202211224322.5 and publication date of November 29, 2022, describes a system for loading materials onto two production lines. When automotive parts are small, it can handle multiple parts of the same or different specifications at once. When automotive parts are large and heavy, multiple clamping components work with specialized fixtures to clamp different parts of the part for loading. The specialized fixtures can be flexibly adjusted for different car models. However, this patent application uses robotic welding and manual loading, generally requiring workers to wait online for welding to complete before loading or unloading. This method has relatively low loading efficiency and high labor intensity for workers.

The first double-guide rod cylinder 502 retracts, and the second double-guide rod cylinder 506 opens.

[0037] The second component 200 is fed in as follows: The sliding bracket 604 moves downward, and the second double-guide rod cylinder 506 of the lower-level storage limiting component 500 retracts. Under the action of gravity, the second component 200 is conveyed to the sliding bracket 604 and awaits robot grabbing.

Two guide plates are installed on both the left and right frames. These guide plates guide the first component and the second component. A lower crossbeam is installed between the left and right frames to connect them. An upper storage guide rail is located on the lower crossbeam and on the basic frame. The upper crossbeam is installed above the left and right frames and is used to fix the left and right frames together. A storage limiting component is installed on the upper crossbeam. The lower sensor is located on the left and right sides of the basic frame via a lower sensor bracket, and the upper sensor is located on the left and right frames via an upper sensor bracket.

3. The double-layer automatic feeding device for automotive parts as described in claim 2, characterized in that: Three lower sensors are provided on both the left and right sides of the basic frame; three upper sensors are provided on both the left and right frames.

4. The double-layer automatic feeding device for automotive parts as described in claim 2, characterized in that: The material storage limiting assembly includes a first cylinder mounting plate, a first double-guide rod cylinder, a first connecting plate, a first limiting plate, a second cylinder mounting plate, a second double-guide rod cylinder, a second connecting plate, and a second limiting plate. The first double-guide rod cylinder is mounted on the upper crossbeam via the first cylinder mounting plate. The first connecting plate is mounted on the movable end of the first double-guide rod cylinder. The first limiting plate is mounted on the first connecting plate and is used to limit the position of the first component or the second component. The second double-guide rod cylinder is mounted on the upper crossbeam via the second cylinder mounting plate. The second connecting plate is mounted on the movable end of the second double-guide rod cylinder. The second limiting plate is mounted on the second connecting plate and is used to limit the position of the first component or the second component.

5. A double-layer automatic feeding device for automotive parts as described in claim 1, characterized in that: The double-layer limiting assembly includes a square tube base plate, a sliding cylinder, a slide rail, a sliding bracket, a guide limiting plate, a slide rail, a stop bar, a lower limiting block, an upper limiting block, a material receiving sensor, and a material receiving sensor bracket. The square tube base plate is disposed at the end of the basic frame. The sliding cylinder is mounted on the square tube base plate. The slide rails are disposed on the left and right sides of the square tube base plate. The sliding bracket is disposed on the sliding block of the slide rail. The lower limit block is disposed below the square tube base plate. The upper limit block is disposed above the square tube base plate. The lower limit block and the upper limit block are used to limit the position of the sliding bracket. The sliding cylinder is used to realize the up and down sliding of the sliding bracket. The guide limit plate is disposed above the sliding bracket. The slide rails are disposed on the left and right sides of the sliding bracket. The slide rails are used for the sliding of the first component and the second component. The stop bar is disposed at the end of the sliding bracket and is used to limit the downward sliding of the first component and the second component. The incoming material sensor is disposed on the incoming material sensor bracket. The incoming material sensor bracket is installed in the middle of the sliding bracket. The incoming material sensor is used to detect and determine whether the first component and the second component are in place.
