Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts processing, and in particular to an automatic feeder for dual hoppers of automotive metal stamping parts. Background Technology
[0002] Automatic feeding refers to the process of automatically supplying and conveying materials by using automated devices or systems to replace manual intervention. This technology is widely used in industrial production, processing and manufacturing, warehousing and logistics and other fields. An automatic feeding mechanism with multiple hoppers is a device used for automatic material supply. It is usually used in industrial production lines or processing processes. This mechanism has multiple hoppers. The automatic feeding mechanism with multiple hoppers can improve the efficiency and stability of the production line and ensure the continuity and consistency of material supply. It is often used in industrial manufacturing, processing and assembly line production and other fields. However, the existing automatic feeding mechanisms with multiple hoppers are not stable enough when feeding, resulting in low work efficiency.
[0003] Traditionally, the feeding process for stamping parts on automated metal production lines involves manually placing sheet metal into the feeder's hopper. The feeder's transfer mechanism, in conjunction with suction cups, then moves the sheet metal to a secondary positioning platform. A robot then picks up the sheet metal, working in conjunction with the mold and punch press to complete the production process. However, traditional feeders only have one hopper, and after the hopper is empty, the sheet metal needs to be re-stacked. This has several drawbacks: when re-stacking, the feeder, robot, and punch press all stop and wait until the hopper is full before manual restarting is possible. Workers are often rushed to complete the feeding process quickly, and the high frequency of changing materials in a single hopper can easily lead to fatigue, distraction, and safety hazards during long hours. Utility Model Content
[0004] The purpose of this invention is to provide an automatic feeder with dual material bins for automotive metal stamping parts, which solves the problems of long runners, heavy weight, waste of raw materials, and long injection molding cycles in ordinary fine-gate three-plate molds.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0021] Example 1, as Figure 1-4As shown, an automatic feeder for dual hoppers of automotive metal stamping parts includes an operating platform structure, a workpiece placement station within the operating platform structure, and a transfer and gripping mechanism located on the upper part of the operating platform structure. The workpiece placement station includes an A discharge hopper area 1 and a B discharge hopper area 2 within the operating platform structure, as well as a secondary positioning and detection platform structure located between the A and B discharge hopper areas. The transfer and gripping mechanism includes a horizontal moving track 3 located on the upper part of the operating platform structure and a workpiece gripping structure located on the horizontal moving track. The secondary positioning and detection platform structure includes a detection and positioning platform 4 located on the operating platform structure between the A and B discharge hopper areas, a set of workpiece adjustment and limiting structures located on the upper part of the detection and positioning platform, and an operating control console 21 located outside the detection and positioning platform. A hydraulic drive station 5 is externally connected to the operating platform structure.
[0022] The operating platform structure includes an operating base 6, a track frame 7 located on the rear side of the operating base, and a protective net 8 located on the upper outer periphery of the operating base.
[0023] Multiple workpiece limiting rods 9 are set on the outer periphery of the A and B material feeding areas.
[0024] The workpiece adjustment and limiting structure includes a placement platform 10 mounted on the detection and positioning stage, and multiple positioning cylinder assemblies located outside the placement platform. Each positioning cylinder assembly includes an outer end cylinder 11 and a bottom end cylinder 12. A side end limiting block 13 is provided at the output end of the outer end cylinder, and a bottom limiting block 14 is provided at the output end of the bottom end cylinder. An upper end limiting block 15 is also provided on the detection and positioning stage at the upper end of each placement platform.

[0026] Multiple safety light curtain components 20 are also provided on the outer periphery of the operating platform.
[0027] The working principle of this invention is as follows: The material sheets are manually placed into bins A and B of the feeder. The transfer mechanism first grabs the material sheets from bin A and places them on the secondary positioning platform. This process is repeated until all the material sheets in bin A are grabbed by the transfer mechanism. Then, the control program issues a command, and the transfer mechanism automatically grabs the material sheets from bin B. Simultaneously, material sheets are manually placed into bin A. After the material sheets are placed, the start button is pressed, and bin A completes its loading process. Once all the material sheets in bin B are grabbed, the control program issues another command, and the transfer mechanism automatically grabs the material sheets from bin A, and this cycle repeats. During this process, the feeder, robot, and punch press do not need to stop waiting. There is ample time for manual loading, and the loading frequency is significantly reduced, making the process easier, more efficient, and safer.
[0028] This structure effectively improves the stability of the device during movement, thereby enhancing the stability of workpiece feeding, improving feeding accuracy, and increasing work efficiency. The average production capacity per person per shift has increased from 2000 pieces / shift to 3500 pieces / shift. It also effectively improves the position of the workpiece within the workpiece adjustment and limiting structure, facilitating suction cup feeding and further increasing work efficiency. It is also easier and safer to use.
